Maternal depression may derail children’s school readiness
based on data from a cohort study of more than 50,000 children.
Previous research supports a link between maternal depression and poor cognitive development in children, but the effect of children’s age when exposed to depression on their development has not been well studied, wrote Elizabeth Wall-Wieler, PhD, of Stanford (Calif.) University, and colleagues.
In a population-based cohort study published in Pediatrics, the researchers examined data from 52,103 children born in Manitoba, Canada who completed the Early Development Instrument (EDI) between 2005 and 2016. The EDI is a 103-item questionnaire given to kindergarteners in a classroom setting during the second half of the school year. The EDI is designed to assess five domains: physical health and well-being, social competence, emotional maturity, language and cognitive development, and communication skills and general knowledge. The researchers assessed maternal depression using a combination of physician visits, hospitalizations, and pharmaceutical data; 19% of the children had a mother diagnosed with depression during the study.
Difficulties emerged in social functioning, emotion regulation
Children whose mothers had a diagnosis of depression before they reached age 5 years had a 1.17 times increased risk of having a problem in one or more of the developmental domains at school entry, compared with those whose mothers had no such diagnosis. Overall, exposure to maternal depression was significantly associated with problems in the areas of social competence (adjusted risk ratio 1.28), physical health and well-being (aRR 1.28), and emotional maturity (aRR 1.27) in kindergarten. For these three domains, children exposed to maternal depression between the ages of 4 and 5 years showed the greatest risk of developmental vulnerability, the researchers said.
“It is noteworthy that these difficulties were reported by the children’s teachers, avoiding negative biases inherent in having mothers with depression serve as informants,” Dr. Wall-Wieler and associates wrote.
The study findings were limited by several factors related to the observational design, including incomplete data on maternal depression prevalence and severity, the researchers said. In addition, the study did not account for confounding variables related to parenting style and information on the presence and psychiatric profiles of fathers.
The results support previous studies by identifying the impact of exposure to maternal depression on particular developmental domains, the researchers concluded. However, more research is needed to extend their findings.
“In particular, investigators should work to elucidate the mechanisms that underlie this intergenerational transmission to young children of mothers with depression at risk for social and emotional difficulties, focusing on aspects of the caregiving environments and behaviors to which these children are exposed,” Dr. Wall-Wieler and associates concluded.
Approximately 70% of the children exposed to maternal depression did not test as vulnerable in any of the developmental domains. Factors that promoted resilience in the children exposed to maternal depression who did not experience developmental vulnerability should be identified, they noted.
Maternal depression is a public health crisis
“The widespread prevalence of maternal depression in the United States and worldwide, with estimates ranging from 3% to 60%, constitutes a public health crisis, particularly one affecting low-income women and their children,” Stephanie Klees Goeglein, MD, and Yvette E. Yatchmink, MD, PhD, of Brown University, Providence, R.I., wrote in an accompanying editorial (Pediatrics. 2020 Aug 17. doi: 10.1542/peds.2020-010413). The study adds to the research and understanding of the negative impact of maternal depression on child development, but also raises questions because some key confounders were not addressed, mainly “the presence of prenatal depression, severity and chronicity of maternal depression, comorbidities, and parenting practices including the involvement of fathers or partners,” they noted.
Don’t discount the impact of prenatal depression, the editorialists stressed. “Surprising to some, prenatal depression is more common than postpartum depression and may be a major, unexplored contributor to the developmental vulnerability of the children in the sample,” Dr. Goeglein and Dr. Yatchmink said.
However, the fact that approximately 70% of the children exposed to maternal depression did not have developmental vulnerability in any domain is encouraging, and speaks to the resiliency of children to overcome adverse conditions, they added.
Pediatricians can play a role in reducing maternal depression by screening mothers starting at a prenatal visit and continuing through post partum, infancy, and beyond. In addition, actions to improve access to mental health care for mothers and to develop culturally-sensitive positive parenting programs may help reduce the effects of depression on mothers and children, Dr. Goeglein and Dr. Yatchmink emphasized.
Empower depressed mothers to seek assistance
The results were not surprising, but a study that “validates that which we feel we know is clinically significant,” Lillian M. Beard, MD, of Children’s National in Washington, said in an interview.
“This study restates why it is so important for us to evaluate and recognize maternal depression,” she said. “As a busy pediatrician, once I recognize a problem, I struggle with how to provide viable professional and valuable community resources for these mothers.
“My take-home message from the study is that we must screen for maternal depression. When we suspect maternal depression, it is usually present,” Dr. Beard said. “While we cannot change all the factors that contribute to this condition, to help the children we serve to be physically and emotionally sound, we must help empower their mothers to seek assistance, when needed, to be emotionally healthy,” she emphasized.
“More research is needed to recognize the efficacy and value of community-based assistance for maternal and family depression,” said Dr. Beard, who was not involved with the study and was asked to comment on the findings.
The study was supported by the Canadian Institutes of Health Research, the National Institute of Mental Health, and the National Institutes of Health. The researchers and editorialists had no financial conflicts to disclose. Dr. Beard, a member of the Pediatric News editorial advisory board, had no relevant financial disclosures.

Compression therapy cuts cellulitis risk in chronic leg edema
The effect was so striking that the randomized controlled trial was stopped early and all patients in the study were given the therapy.
“In a climate of increasing antibiotic resistance, we are delighted to have discovered a nondrug management strategy that has such a dramatic impact on the risk of cellulitis,” senior author Bernie Bissett, PhD, from the Discipline of Physiotherapy, Faculty of Health, the University of Canberra, Australia, said in an interview.
“We hope this leads to a shift in preventative medical strategy for patients with chronic edema and cellulitis around the world,” she said.
Lead author Elizabeth Webb, MPH, from the Physiotherapy Department at Calvary Public Hospital Bruce, in Bruce, Australia, and colleagues report their findings in an article published online August 12 in The New England Journal of Medicine.
Dr. Bisset explained that Webb is a “leading lymphedema physiotherapist” and a PhD candidate at the University of Canberra. She added that this is the first study to show that “compression therapy dramatically reduces the risk of cellulitis for patients with chronic edema.”
Penicillin is often given preventively; some research suggests effectiveness wanes after the antibiotic is stopped.
For the current trial, Ms. Webb and colleagues enrolled 84 adults with chronic edema of the leg and recurrent cellulitis. They randomly assigned patients in a 1:1 ratio to receive leg compression therapy plus education about preventing cellulitis (compression group; n = 41) or education only (control group; n = 43).
Compression therapy consisted of wearing knee-high stockings that applied maximum compression at the ankles. The compression gradually decreased up the legs. In addition, 26 patients were treated with “therapist-applied compression bandaging” for 3 to 5 days before receiving the stockings.
Participants underwent follow-up assessments every 6 months for a maximum of 3 years or until 45 episodes of cellulitis, the primary outcome, occurred. Those in the control group crossed over to the compression group once they experienced cellulitis.
The trial was stopped early for reasons of efficacy. “The statistical analysis plan prespecified that after 23 episodes of cellulitis had occurred, an independent data monitoring committee would review the results of the interim analysis and recommend whether the trial should stop early,” the authors write.
At the time of the monitoring committee’s review, six patients (15%) who wore compression stockings and 17 (40%) in the control group had experienced a cellulitis episode (hazard ratio, 0.23; P = .002; relative risk [post hoc analysis], 0.37; P = .02). On the basis of those findings, the researchers stopped the study, and patients in the control group were started on compression therapy.
“Clinicians should definitely consider referring their patients to a skilled lymphedema therapist who can individually prescribe and fit compression garments,” Dr. Bissett said. “In our study, these were well tolerated and reduced the risk of another episode of cellulitis by a huge 77%,” she added.
Secondary outcomes included hospitalization related to cellulitis and quality-of-life assessments.
Three patients (7%) in the compression group and six (14%) in the control group were admitted to the hospital for cellulitis (hazard ratio, 0.38). There were no differences in quality of life outcomes between the treatment groups.
The authors say compression therapy has the potential to decrease cellulitis risk by reducing edema, boosting immune response and skin integrity, and protecting the skin.
“Patients with a history of leg swelling (chronic edema) and previous episodes of cellulitis are ideal candidates for this compression therapy,” Dr. Bissett said.
“Given the lack of side effects of the therapy in our study and the potential to reduce other skin problems in these patients, compression therapy is an ideal prophylactic strategy,” she said.
The authors note several study limitations, including a lack of blinding. In addition, patients in the study had to have access to lymphedema specialists, who might be unavailable to patients outside the study. This could have influenced adherence and limit generalizability. Difficulty putting on and taking off compression garments often leads patients to be less adherent to compression therapy, but 88% of patients in this study wore them at least 4 days per week.
Dr. Bissett said compression therapy would be useful for primary care physicians to consider for patients with chronic edema.
“Primary care physicians are highly likely to encounter patients with chronic edema in their day-to-day practice. We can now confidently say that referral to lymphedema therapists for compression therapy should be a first line of defense against future episodes of cellulitis in this vulnerable patient group,” she explained.
The authors have disclosed no relevant financial relationships.

Anxiety disorders begin earlier in life, differ by gender
Anxiety disorders start very early in life and may manifest themselves first as other conditions like social anxiety disorder, according to Jeffrey R. Strawn, MD.
An adolescent presenting to a mental health clinician with anxiety at 16 years old, for example has likely struggled with her anxiety for years before visiting a clinic. “That child may have been someone who had separation anxiety earlier in life and who as, even an infant, had behavioral inhibitions, that reluctance or timidness to explore new things, that tendency to retreat from novel stimuli,” Dr. Strawn, associate professor of psychiatry, pediatrics and clinical pharmacology at Cincinnati Children’s Hospital Medical Center, said at Focus on Neuropsychiatry presented by Current Psychiatry and the American Academy of Clinical Psychiatrists. “Anxiety disorders are enduring and persistent, and they begin very early in life.”
Social anxiety disorder is one of the first anxiety disorders that appear in childhood or adolescents, which rises during puberty and during a time in a child’s life when they are dealing with new social pressures and challenges, such as graduating from elementary to middle school, Dr. Strawn noted. Generalized anxiety disorder is usually the next to emerge, followed by panic disorder. On the other hand, agoraphobia, another anxiety disorder that begins in childhood, “often represents behavioral avoidance as opposed to agoraphobia as we classically think about it as adult psychiatrists.”
Onset of anxiety disorders also differ by gender. “In terms of the emergence of these anxiety disorders, another thing that’s important to know is that the onset seems to be a bit different with regard to girls and boys. We see that break there emerging really around the time of puberty or as people are moving into late puberty, at least for girls,” Dr. Strawn said at the meeting presented by Global Academy for Medical Education. .
A shift occurs in amygdala prefrontal circuitry as children age, Dr. Strawn explained. Younger children do not have the ability to modulate the amygdala with their prefrontal cortex, but this amygdala–medial prefrontal cortex functional connectivity will change as children grow. A study by Dylan G. Gee, PhD, and colleagues found positive amygdala–medial prefrontal cortex functional connectivity at younger than 10 years old, and a “steady decline in amygdala activity” from 10-13 years to adulthood at 22 years old (J Neurosci. 2013 Mar 6;33[10]:4584-93).
“In essence, what we’re seeing is that there’s improvement or more effectiveness in terms of that connection between the prefrontal cortex, the amygdala, and that ability to amplify the brake to the amygdala,” Dr. Strawn said.
SSRIs, SNRIs for pediatric patients
Selective serotonin reuptake inhibitors can be effective for pediatric patients with anxiety disorders. Results from the Child/Adolescent Anxiety Multimodal Study (CAMS) show that patients with generalized separation or social anxiety disorder treated with sertraline or cognitive-behavioral therapy (CBT) for 3 months responded better to treatment than placebo. A combination of sertraline and CBT performing best, compared with either intervention alone (N Engl J Med. 2008;359:2753-66).
When examining treatment response in 76 patients from CAMS, the researchers saw improvement at 4 weeks from baseline in patients with anxiety symptoms receiving CBT, but no significant change in improvement after 4 weeks up to 12 weeks (J Child Adolesc Psychopharm. 2017 Aug 1. doi: 10.1089/cap.2016.0198).
“What that actually means is that your improvement at week 4 is better than your improvement at baseline, and your improvement at week 8 is greater than your improvement at week 4. Similarly, in your improvement, week 12 is greater than your improvement at week 8,” Dr. Strawn said.
However, “that’s not the case for aggressively titrated sertraline,” which had no statistically significant difference in improvement at 8 weeks and 12 weeks, he explained. “What this actually means is that, if I have not had improvement by week 8, there is a three-to-one odds against improvement over those next 4 weeks. The take-home message here is really that an adequate trial for an SSRI in pediatric anxiety disorders is probably about 8 weeks – not 12, not longer.”
Serotonin norepinephrine reuptake inhibitors (SNRIs) are also effective in pediatric patients with anxiety disorders.
“Both SNRIs as well as SSRIs have certainly demonstrated efficacy in terms of treating pediatric patients with anxiety, but there is a very important difference here with regard to the trajectory of improvement and also the magnitude of improvement,” Dr. Strawn said. SNRIs like atomoxetine, duloxetine, or venlafaxine “do not improve as rapidly and do not improve to the same extent as kids who are treated with an SSRI.”
Dose is another factor that affects symptom improvement in patients with pediatric anxiety disorders. In a 2018 meta-analysis, Dr. Strawn and colleagues found that patients treated with a higher dose of SSRIs demonstrated more rapid improvement at 2 weeks, compared with patients who received SNRIs (P = .002), but there was no significant difference in overall response trajectory (J Am Acad Child Adolesc Psychiatry. 2018 Apr;57[4]:235-44.E2).
Response to SSRIs can depend a patient’s genotype, Dr. Strawn said. The serotonin transporter promotor polymorphism has received “considerable attention in adults with depressive disorders primarily” but also might play a role in anxiety disorder response in pediatric patients. One study presented by his group at the 2019 annual meeting of the American Academy of Child & Adolescent Psychiatry showed that patients with a short-short copy of the serotonin transporter promoter polymorphism instead of a long copy had “shallower and less improvement over the course of treatment” when taking escitalopram.
“This is something that doesn’t necessarily compel us to use an SNRI over an SSRI, but it’s something that does give us some important information in terms of the trajectory of improvement,” he said.
When it comes to side effects of SNRIs and SSRIs, the profile is “pretty consistent with what we know to be the side effect profile in adults with depressive and anxiety disorders,” Dr. Strawn noted. “SNRIs tend to be a little bit better tolerated, both in terms of adverse event–related discontinuation and also in terms of their likelihood of producing activation.”
Patient and caregiver expectations can further affect response to treatment. “I think this has implications in terms of how we actively manage expectations and discussions about the evidence for interventions with our patients in the clinic.”

Anxiety disorders start very early in life and may manifest themselves first as other conditions like social anxiety disorder, according to Jeffrey R. Strawn, MD.
An adolescent presenting to a mental health clinician with anxiety at 16 years old, for example has likely struggled with her anxiety for years before visiting a clinic. “That child may have been someone who had separation anxiety earlier in life and who as, even an infant, had behavioral inhibitions, that reluctance or timidness to explore new things, that tendency to retreat from novel stimuli,” Dr. Strawn, associate professor of psychiatry, pediatrics and clinical pharmacology at Cincinnati Children’s Hospital Medical Center, said at Focus on Neuropsychiatry presented by Current Psychiatry and the American Academy of Clinical Psychiatrists. “Anxiety disorders are enduring and persistent, and they begin very early in life.”
Social anxiety disorder is one of the first anxiety disorders that appear in childhood or adolescents, which rises during puberty and during a time in a child’s life when they are dealing with new social pressures and challenges, such as graduating from elementary to middle school, Dr. Strawn noted. Generalized anxiety disorder is usually the next to emerge, followed by panic disorder. On the other hand, agoraphobia, another anxiety disorder that begins in childhood, “often represents behavioral avoidance as opposed to agoraphobia as we classically think about it as adult psychiatrists.”
Onset of anxiety disorders also differ by gender. “In terms of the emergence of these anxiety disorders, another thing that’s important to know is that the onset seems to be a bit different with regard to girls and boys. We see that break there emerging really around the time of puberty or as people are moving into late puberty, at least for girls,” Dr. Strawn said at the meeting presented by Global Academy for Medical Education. .
A shift occurs in amygdala prefrontal circuitry as children age, Dr. Strawn explained. Younger children do not have the ability to modulate the amygdala with their prefrontal cortex, but this amygdala–medial prefrontal cortex functional connectivity will change as children grow. A study by Dylan G. Gee, PhD, and colleagues found positive amygdala–medial prefrontal cortex functional connectivity at younger than 10 years old, and a “steady decline in amygdala activity” from 10-13 years to adulthood at 22 years old (J Neurosci. 2013 Mar 6;33[10]:4584-93).
“In essence, what we’re seeing is that there’s improvement or more effectiveness in terms of that connection between the prefrontal cortex, the amygdala, and that ability to amplify the brake to the amygdala,” Dr. Strawn said.
SSRIs, SNRIs for pediatric patients
Selective serotonin reuptake inhibitors can be effective for pediatric patients with anxiety disorders. Results from the Child/Adolescent Anxiety Multimodal Study (CAMS) show that patients with generalized separation or social anxiety disorder treated with sertraline or cognitive-behavioral therapy (CBT) for 3 months responded better to treatment than placebo. A combination of sertraline and CBT performing best, compared with either intervention alone (N Engl J Med. 2008;359:2753-66).
When examining treatment response in 76 patients from CAMS, the researchers saw improvement at 4 weeks from baseline in patients with anxiety symptoms receiving CBT, but no significant change in improvement after 4 weeks up to 12 weeks (J Child Adolesc Psychopharm. 2017 Aug 1. doi: 10.1089/cap.2016.0198).
“What that actually means is that your improvement at week 4 is better than your improvement at baseline, and your improvement at week 8 is greater than your improvement at week 4. Similarly, in your improvement, week 12 is greater than your improvement at week 8,” Dr. Strawn said.
However, “that’s not the case for aggressively titrated sertraline,” which had no statistically significant difference in improvement at 8 weeks and 12 weeks, he explained. “What this actually means is that, if I have not had improvement by week 8, there is a three-to-one odds against improvement over those next 4 weeks. The take-home message here is really that an adequate trial for an SSRI in pediatric anxiety disorders is probably about 8 weeks – not 12, not longer.”
Serotonin norepinephrine reuptake inhibitors (SNRIs) are also effective in pediatric patients with anxiety disorders.

Pulmonary rehab reduces COPD readmissions
Pulmonary rehabilitation reduces the likelihood that patients with chronic obstructive pulmonary disease (COPD) will be readmitted to the hospital in the year after discharge by 33%, new research shows, but few patients participate in those programs.
In fact, in a retrospective cohort of 197,376 patients from 4446 hospitals, only 1.5% of patients initiated pulmonary rehabilitation in the 90 days after hospital discharge.
“This is a striking finding,” said Mihaela Stefan, PhD, from the University of Massachusetts Medical School–Baystate in Springfield. “Our study demonstrates that we need to increase access to rehabilitation to reduce the risk of readmissions.”
Not enough patients are initiating rehabilitation, but the onus is not only on them; the system is failing them. “We wanted to understand how much pulmonary rehabilitation lowers the readmission rate,” Stefan told Medscape Medical News.
So she and her colleagues examined the records of patients who were hospitalized for COPD in 2014 to see whether they had begun rehabilitation in the 90 days after discharge and whether they were readmitted to the hospital in the subsequent 12 months.
Patients who were unlikely to initiate pulmonary rehabilitation — such as those with dementia or metastatic cancer and those discharged to hospice care or a nursing home — were excluded from the analysis, Stefan said during her presentation at the study results at the virtual American Thoracic Society (ATS) 2020 International Conference.
The risk analysis was complex because many patients died before the year was out, and “a patient who dies has no risk of being readmitted,” she explained. Selection bias was also a factor because patients who do pulmonary rehab tend to be in better shape.
The researchers used propensity score matching and Anderson–Gill models of cumulative rehospitalizations or death at 1 year with time-varying exposure to pulmonary rehabilitation to account for clustering of individual events and adjust for covariates. “It was a complicated risk analysis,” she said.
In the year after discharge, 130,660 patients (66%) were readmitted to the hospital. The rate of rehospitalization was lower for those who initiated rehabilitation than for those who did not (59% vs 66%), as was the mean number of readmissions per patient (1.4 vs 1.8).
Rehabilitation was associated with a lower risk for readmission or death (hazard ratio, 0.67; 95% CI, 0.66 - 0.69).
“We know the referral rates are low and that pulmonary rehabilitation is effective in clinical trials,” said Stefan, and now “we see that pulmonary rehabilitation is effective when you look at patients in real life.”
From a provider perspective, “we need to make sure that hospitals get more money for pulmonary rehabilitation. Cardiac rehabilitation is paid for,” she explained. "But pulmonary rehab is not a lucrative business. I don›t know why the CMS pays more for cardiac."
A rehabilitation program generally consists of 36 sessions, held two or three times a week, and many patients can’t afford that on their own, she noted. Transportation is another huge issue.
A recent study in which semi-structured interviews were conducted with 15 COPD patients showed that the main barriers to enrollment in a pulmonary rehabilitation program are lack of awareness, family obligations, transportation, and lack of motivation, said Stefan, who was involved in that research.
Telehealth rehabilitation programs might become more available in the near future, given the COVID pandemic. But “currently, Medicare doesn’t pay for telerehab,” she said. Virtual sessions might attract more patients, but lack of computer access and training could present another barrier for some.
PAH rehab
Uptake for pulmonary rehabilitation is as low for patients with pulmonary arterial hypertension (PAH) as it is for those with COPD, according to another study presented at the virtual ATS meeting.
An examination of the electronic health records of 111,356 veterans who experienced incident PAH from 2010 to 2016 showed that only 1,737 (1.6%) followed through on pulmonary rehabilitation.
“Exercise therapy is safe and effective at improving outcomes,” lead author Thomas Cascino, MD, from the University of Michigan in Ann Arbor, said in an ATS press release. “Recognizing that it is being underutilized is a necessary first step in working toward increasing patient access to rehab.
His group is currently working on a trial for home-based rehabilitation “using wearable technology as a means to expand access for people unable to come to center-based rehab for a variety of reasons,” he explained.
“The goal of all our treatments is to help people feel better and live longer,” Cascino added.
Stefan and Cascino have disclosed no relevant financial relationships.

A 4-year-old with a lesion on her cheek, which grew and became firmer over two months
The patient was diagnosed with idiopathic facial aseptic granuloma (IFAG) based on the clinical findings, as well as the associated history of chalazia and erythematous papules seen in childhood rosacea.
She was treated with several months of azithromycin, sulfur wash, and metronidazole cream with improvement of some of the smaller lesions but no change on the larger nodules. Later she was treated with oral and topical ivermectin with no improvement. Some of the nodules slowly resolved except for the larger lesion on the right cheek. She was later treated with a 6-week course of clarithromycin with partial improvement of the nodule. The lesion resolved after 2 months of stopping clarithromycin.
IFAG is a rare condition seen in prepubescent children. The etiology of this condition is not well understood and is thought to be on the spectrum of childhood rosacea.1 From several recent reports, IFAG usually is seen in children with associated conditions including chalazia, conjunctivitis, blepharitis, and telangiectasias, which can be seen in patients with rosacea. These associated findings suggest the possibility of IFAG being a form of granulomatous rosacea in children.
This condition presents in childhood between the ages of 8 months and 13 years. Most of the cases occur in toddlers, and girls appear to be more affected than boys. The lesions appear as pink, rubbery, nontender, nonfluctuant nodules on the cheeks, which can be single or multiple. A large prospective study in 30 children demonstrated that more 70% of the lesions cultured were negative for bacteria. Histologic analysis of some of the lesions showed a chronic dermal lymphohistiocytic granulomatous perifollicular infiltrate with numerous foreign body–type giant cells.2
The differential diagnosis of these lesions should include infectious pyodermas such as mycobacterial infections, cutaneous leishmaniasis, and botryomycosis; deep fungal infections such as sporotrichosis, coccidioidomycosis, and cryptococcosis; childhood nodulocystic acne; pilomatrixoma; epidermoid cyst; vascular tumors or malformations; and leukemia cutis.3
The diagnosis is usually clinical but in atypical cases a skin biopsy with tissue cultures should be performed. The decision to biopsy these lesions will need to be done in a one by one basis, as a biopsy may leave scaring on the area affected.
It has been postulated that a color Doppler ultrasound of the lesion may be a helpful ancillary study. Echographic findings show a well demarcated solid-cystic, hypoechoic dermal lesion, the largest axis of which lies parallel to the skin surface. The lesion lacks calcium deposits. Other findings include increased echogenicity of the underlaying hypodermis. The findings may vary depending on the stage of the lesion.4
The course of the condition may last on average months to years. Some lesions resolve spontaneously and others may respond to courses of oral antibiotics such as clarithromycin, azithromycin, or ivermectin. In our patient, several lesions improved with oral antibiotics, but the larger lesions were more persistent and resolved after a year.
The lesions usually resolve without scarring. In those patients with associated rosacea, maintenance topical treatments may be warranted and also may need follow-up with ophthalmology because they tend to commonly have ocular rosacea as well.

IFAG is a rare condition seen in prepubescent children. The etiology of this condition is not well understood and is thought to be on the spectrum of childhood rosacea.1 From several recent reports, IFAG usually is seen in children with associated conditions including chalazia, conjunctivitis, blepharitis, and telangiectasias, which can be seen in patients with rosacea. These associated findings suggest the possibility of IFAG being a form of granulomatous rosacea in children.
This condition presents in childhood between the ages of 8 months and 13 years. Most of the cases occur in toddlers, and girls appear to be more affected than boys. The lesions appear as pink, rubbery, nontender, nonfluctuant nodules on the cheeks, which can be single or multiple. A large prospective study in 30 children demonstrated that more 70% of the lesions cultured were negative for bacteria. Histologic analysis of some of the lesions showed a chronic dermal lymphohistiocytic granulomatous perifollicular infiltrate with numerous foreign body–type giant cells.2
The differential diagnosis of these lesions should include infectious pyodermas such as mycobacterial infections, cutaneous leishmaniasis, and botryomycosis; deep fungal infections such as sporotrichosis, coccidioidomycosis, and cryptococcosis; childhood nodulocystic acne; pilomatrixoma; epidermoid cyst; vascular tumors or malformations; and leukemia cutis.3
The diagnosis is usually clinical but in atypical cases a skin biopsy with tissue cultures should be performed. The decision to biopsy these lesions will need to be done in a one by one basis, as a biopsy may leave scaring on the area affected.
It has been postulated that a color Doppler ultrasound of the lesion may be a helpful ancillary study. Echographic findings show a well demarcated solid-cystic, hypoechoic dermal lesion, the largest axis of which lies parallel to the skin surface. The lesion lacks calcium deposits. Other findings include increased echogenicity of the underlaying hypodermis. The findings may vary depending on the stage of the lesion.4
The course of the condition may last on average months to years. Some lesions resolve spontaneously and others may respond to courses of oral antibiotics such as clarithromycin, azithromycin, or ivermectin. In our patient, several lesions improved with oral antibiotics, but the larger lesions were more persistent and resolved after a year.
The lesions usually resolve without scarring. In those patients with associated rosacea, maintenance topical treatments may be warranted and also may need follow-up with ophthalmology because they tend to commonly have ocular rosacea as well.

The patient was diagnosed with idiopathic facial aseptic granuloma (IFAG) based on the clinical findings, as well as the associated history of chalazia and erythematous papules seen in childhood rosacea.
She was treated with several months of azithromycin, sulfur wash, and metronidazole cream with improvement of some of the smaller lesions but no change on the larger nodules. Later she was treated with oral and topical ivermectin with no improvement. Some of the nodules slowly resolved except for the larger lesion on the right cheek. She was later treated with a 6-week course of clarithromycin with partial improvement of the nodule. The lesion resolved after 2 months of stopping clarithromycin.

A 4-year-old female is brought to our pediatric dermatology clinic for evaluation of a persistent lesion on the cheek.
The mother of the child reports that the lesion started as a small "bug bite" and then started growing and getting firmer for the past 2 months. The girl has developed other smaller red, pimple-like lesions on the cheeks and one of them is starting to increase in size.
She denies any tenderness on the area or any purulent discharge. She has had no fevers, chills, weight loss, nose bleeds, fatigue, or any other symptoms. The mother has not noted any changes on the child's body odor, any rapid growth, or hair on her axillary or pubic area. She was treated with three different courses of oral antibiotics including cephalexin, trimethoprim/sulfamethoxazole, and clindamycin, as well as topical mupirocin, with no improvement.
Her past medical history is significant for several episodes of eyelid cysts that were treated with warm compresses and topical erythromycin ointment. The family history is significant for the father having severe acne as a teenager. She has two cats, she has not traveled, and she has an older sister who has no lesions.
On physical examination she is a lovely 4-year-old female in no acute distress. Her height is on the 70th percentile and weight on the 40th percentile for her age. Her blood pressure is 95/84 with a heart rate of 96. On skin examination she has several pink macules and papules on her bilateral cheeks. On the left cheek there are two pink nodules: One is 1 cm, and the other is 7 mm. The nodules are not tender. There is no warmth, fluctuance, or discharge from the lesions.
She has no cervical lymphadenopathy. She has no axillary or pubic hair. She is Tanner stage I.

Can’t Miss Heart Disease for Hospitalists
Presenter
Erich Maul, DO, MPH, FAAP, SFHM
Session summary
Dr. Erich Maul, professor of pediatrics, medical director for progressive care and acute care, and chief of hospital pediatrics at Kentucky Children’s Hospital, Lexington, presented an engaging, case-based approach to evaluate heart disease when “on call.” He iterated the importance of recognizing congenital heart disease, especially since 25% of these patients usually need surgical intervention within the first month of diagnosis and about 50% of congenital heart disease patients do not have a murmur.
Presenting cases seen during a busy hospitalist call night, Dr. Maul highlighted that patients can present with signs of heart failure, cyanosis, sepsis or hypoperfusion, failure to thrive, and respiratory distress or failure. He discussed the presentation, epidemiology, diagnosis, treatment, and prognosis. He also provided examples of common arrhythmias and provided refreshers on management using basic life support (BLS) and pediatric advanced life support.
Key takeaways
- Always start with the nine steps to resuscitation: ABC (airway, breathing, circulation), ABC, oxygen, access, monitoring.
- Early BLS is important.
- Congenital heart disease often presents with either cyanosis, hypoperfusion, failure to thrive, or respiratory distress.

SGLT2 inhibitors with metformin look safe for bone
The combination of sodium-glucose transporter-2 (SGLT-2) inhibitors and metformin is not associated with an increase in fracture risk among patients with type 2 diabetes (T2D), according to a new meta-analysis of 25 randomized, controlled trials.
Researchers at The Second Clinical College of Dalian Medical University in Jiangsu, China, compared fracture risk associated with the metformin/SLGT2 combination to metformin alone as well as other T2D therapeutics, and found no differences in risk. The study was published online Aug. 11 in Osteoporosis International.
T2D is associated with an increased risk of fracture, though causative mechanisms remain uncertain. Some lines of evidence suggest multiple factors may contribute to fractures, including hyperglycemia, oxidative stress, toxic effects of advanced glycosylation end-products, altered insulin levels, and treatment-induced hypoglycemia, as well as an association between T2D and increased risk of falls.
Antidiabetes drugs can have positive or negative effects on bone. thiazolidinediones, insulin, and sulfonylureas may increase risk of fractures, while dipeptidyl peptidase-4 (DPP-4) inhibitors and glucagon-like peptide-2 (GLP-2) receptor agonists may be protective. Metformin may also reduce fracture risk.
SGLT-2 inhibitors interrupt glucose reabsorption in the kidney, leading to improved glycemic control. Other benefits include improved renal and cardiovascular outcomes, weight loss, and reduced blood pressure, liver fat, and serum uric acid levels.
These properties have made SGLT-2 inhibitors combined with metformin an important therapy for patients at high risk of atherosclerotic disease, or who have heart failure or chronic kidney disease.
But SGLT-2 inhibition increases osmotic diuresis, and this could alter the mineral balance within bone. Some studies also showed that SGLT-2 inhibitors led to changes in bone turnover markers, bone mineral density, and bone microarchitecture. Observational studies of the SGLT-2 inhibitor canagliflozin found associations with a higher rate of fracture risk in patients taking the drug.
Such studies carry the risk of confounding factors, so the researchers took advantage of the fact that many recent clinical trials have examined the impact of SGLT-2 inhibitors on T2D. They pooled data from 25 clinical trials with a total of 19,500 participants, 9,662 of whom received SGLT-2 inhibitors plus metformin; 9,838 received other active comparators.
The fracture rate was 0.91% in the SGLT-2 inhibitors/metformin group, and 0.80% among controls (odds ratio, 0.97; 95% CI, 0.71-1.32), with no heterogeneity. Metformin alone was not associated with a change in fracture rate (OR, 0.95; 95% CI, 0.44-2.08), nor were other forms of diabetes control (OR, 0.95; 95% CI, 0.69-1.31).
There were some differences in fracture risk among SGLT-2 inhibitors when studied individually, though none differed significantly from controls. The highest risk was associated with the canagliflozin/metformin (OR, 2.19; 95% CI, 0.66-7.27), followed by dapagliflozin/metformin (OR, 0.91; 95% CI, 0.50-1.64), empagliflozin/metformin (OR, 0.94; 95% CI, 0.59-1.50), and ertugliflozin/metformin (OR, 0.76; 95% CI, 0.38-1.54).
There were no differences with respect to hip or lumbar spine fractures, or other fractures. The researchers found no differences in bone mineral density or bone turnover markers.
The meta-analysis is limited by the relatively short average follow-up in the included studies, which was 61 weeks. Bone damage may occur over longer time periods. Bone fractures were also not a prespecified adverse event in most included studies.
The studies also did not provide detailed information on the types of fractures experienced, such as whether they were result of a fall, or the location of the fracture, or bone health parameters. Although the results support a belief that SGLT-2 inhibitors do not adversely affect bone health, “given limited information on bone health outcomes, further work is needed to validate this conclusion,” the authors wrote.
The authors did not disclose any funding and had no relevant conflicts of interest.

COVID-19 child case count now over 400,000
according to a new report from the American Academy of Pediatrics and the Children’s Hospital Association.
The 406,000 children who have tested positive for COVID-19 represent 9.1% of all cases reported so far by 49 states (New York does not provide age distribution), New York City, the District of Columbia, Puerto Rico, and Guam. Since the proportion of child cases also was 9.1% on Aug. 6, the most recent week is the first without an increase since tracking began in mid-April, the report shows.
State-level data show that Wyoming has the highest percentage of child cases (16.6%) after Alabama changed its “definition of child case from 0-24 to 0-17 years, resulting in a downward revision of cumulative child cases,” the AAP and the CHA said. Alabama’s proportion of such cases dropped from 22.5% to 9.0%.
New Jersey had the lowest rate (3.1%) again this week, along with New York City, but both were up slightly from the week before, when New Jersey was at 2.9% and N.Y.C. was 3.0%. The only states, other than Alabama, that saw declines over the last week were Arkansas, Massachusetts, Mississippi, South Dakota, Texas, and West Virginia. Texas, however, has reported age for only 8% of its confirmed cases, the report noted.
The overall rate of child COVID-19 cases as of Aug. 13 was 538 per 100,000 children, up from 500.7 per 100,000 a week earlier. Arizona was again highest among the states with a rate of 1,254 per 100,000 (up from 1,206) and Vermont was lowest at 121, although Puerto Rico (114) and Guam (88) were lower still, the AAP/CHA data indicate.
For the nine states that report testing information for children, Arizona has the highest positivity rate at 18.3% and West Virginia has the lowest at 3.6%. Data on hospitalizations – available from 21 states and N.Y.C. – show that 3,849 children have been admitted, with rates varying from 0.2% of children in Hawaii to 8.8% in the Big Apple, according to the report.
More specific information on child cases, such as symptoms or underlying conditions, is not being provided by states at this time, the AAP and CHA pointed out.

For the nine states that report testing information for children, Arizona has the highest positivity rate at 18.3% and West Virginia has the lowest at 3.6%. Data on hospitalizations – available from 21 states and N.Y.C. – show that 3,849 children have been admitted, with rates varying from 0.2% of children in Hawaii to 8.8% in the Big Apple, according to the report.
More specific information on child cases, such as symptoms or underlying conditions, is not being provided by states at this time, the AAP and CHA pointed out.
Are aging physicians a burden?
The evaluation of physicians with alleged cognitive decline
As forensic evaluators, we are often asked to review and assess the cognition of aging colleagues. The premise often involves a minor mistake, a poor choice of words, or a lapse in judgment. A physician gets reported for having difficulty using a new electronic form, forgetting the dose of a brand new medication, or getting upset in a public setting. Those behaviors often lead to mandatory psychiatric evaluations. Those requirements are often perceived by the provider as an insult, and betrayal by peers despite many years of dedicated work.
Interestingly, we have noticed many independent evaluators and hospital administrators using this opportunity to send many of our colleagues to pasture. There seems to be an unspoken rule among some forensic evaluators that physicians should represent some form of apex of humanity, beyond reproach, and beyond any fault. Those evaluators will point to any mistake on cognitive scales as proof that the aging physician is no longer safe to practice.1 Forgetting that Jill is from Illinois in the Saint Louis University Mental Status Examination test or how to copy a three-dimensional cube on the Montreal Cognitive Assessment can cost someone their license.2 We are also aware of some evaluators even taking the step further and opining that physicians not only need to score adequately but also demonstrate cognition significantly above average to maintain their privileges.
There is certainly significant appeal in setting a high bar for physicians. In many ways, physicians are characterized in society by their astuteness, intelligence, and high ethical standards. Patients place their lives in the hands of physicians and should trust that those physicians have the cognitive tools to heal them. It could almost seem evident that physicians should have high IQs, score perfectly on screening tools for dementia, and complete a mandatory psychiatric evaluation without any reproach. Yet the reality is often more complex.
We have two main concerns about the idea that we should be intransigent with aging physicians. The first one is the vast differential diagnosis for minor mistakes. An aging physician refusing to comply with a new form or yelling at a clerk once when asked to learn a new electronic medical record are inappropriate though not specific assessments for dementia. Similarly, having significant difficulty learning a new electronic medical record system more often is a sign of ageism rather than cognitive impairment. Subsequently, when arriving for their evaluation, forgetting the date is a common sign of anxiety. A relatable analogy would be to compare the mistake with a medical student forgetting part of the anatomy while questioning by an attending during surgery. Imagine such medical students being referred to mandatory psychiatric evaluation when failing to answer a question during rounds.
In our practice, the most common reason for those minor mistakes during our clinical evaluation is anxiety. After all, patients who present for problems completely unrelated to cognitive decline make similar mistakes. Psychological stressors in physicians require no introduction. The concept is so prevalent and pervasive that it has its own name, “burnout.” Imagine having dedicated most of one’s life to a profession then being enumerated a list of complaints, having one’s privileges put on hold, then being told to complete an independent psychiatric evaluation. If burnout is in part caused by a lack of control, unclear job expectations, rapidly changing models of health care, and dysfunctional workplace dynamics, imagine the consequence of such a referral.
The militant evaluator will use jargon to vilify the reviewed physician. If the physician complains too voraciously, he will be described as having signs of frontotemporal dementia. If the physician comes with a written list of rebuttals, he will be described as having memory problems requiring aids. If the physician is demoralized and quiet, he will be described as being withdrawn and apathetic. If the physician refuses to use or has difficulty with new forms or electronic systems, he will be described as having “impaired executive function,” an ominous term that surely should not be associated with a practicing physician.
The second concern arises from problems with the validity and use of diagnoses like mild cognitive impairment (MCI). MCI is considered to be a transition stage when one maintains “normal activities of daily living, and normal general cognitive function.”3 The American Psychiatric Association Textbook of Psychiatry mentions that there are “however, many cases of nonprogressive MCI.” Should a disorder with generally normal cognition and unclear progression to a more severe disorder require one to be dispensed of their privileges? Should any disorder trump an assessment of functioning?
It is our experience that many if not most physicians’ practice of medicine is not a job but a profession that defines who they are. As such, their occupational habits are an overly repeated and ingrained series of maneuvers analogous to so-called muscle memory. This kind of ritualistic pattern is precisely the kind of cognition that may persist as one starts to have some deficits. This requires the evaluator to be particularly sensitive and cognizant that one may still be able to perform professionally despite some mild but notable deficits. While it is facile to diagnose someone with MCI and justify removing their license, a review of their actual clinical skills is, despite being more time consuming, more pertinent to the evaluation.
In practice, we find that many cases lie in a gray area, which is hard to define. Physicians may come to our office for an evaluation after having said something odd at work. Maybe they misdosed a medication on one occasion. Maybe they wrote the wrong year on a chart. However, if the physician was 30 years old, would we consider any one of those incidents significant? As a psychiatrist rather than a physician practicing the specialty in review, it is particularly hard and sometimes unwise to condone or sanction individual incidents.
Evaluators find solace in neuropsychological testing. However the relevance to the safety of patients is unclear. Many of those tests end up being a simple proxy for age. A physicians’ ability to sort words or cards at a certain speed might correlate to cognitive performance but has unclear significance to the ability to care for patients. Using such tests becomes a de facto age limit on the practice of medicine. It seems essential to expand and refine our repertoire of evaluation tools for the assessment of physicians. As when we perform capacity evaluation in the hospital, we enlist the assistance of the treating team in understanding the questions being asked for a patient, medical boards could consider creating independent multidisciplinary teams where psychiatry has a seat along with the relevant specialties of the evaluee. Likewise, the assessment would benefit from a broad review of the physicians’ general practice rather than the more typical review of one or two incidents.
We are promoting a more individualized approach by medical boards to the many issues of the aging physician. Retiring is no longer the dream of older physicians, but rather working in the suitable position where their contributions, clinical experience, and wisdom are positive contributions to patient care. Furthermore, we encourage medical boards to consider more nuanced decisions. A binary approach fits few cases that we see. Surgeons are a prime example of this. A surgeon in the early stages of Parkinsonism may be unfit to perform surgery but very capable of continuing to contribute to the well-being of patients in other forms of clinical work, including postsurgical care that doesn’t involve physical dexterity. Similarly, medical boards could consider other forms of partial restrictions, including a ban on procedures, a ban on hospital privileges, as well as required supervision or working in teams. Accumulated clinical wisdom allows older physicians to be excellent mentors and educators for younger doctors. There is no simple method to predict which physicians may have the early stages of a progressive dementia, and which may have a stable MCI. A yearly reevaluation if there are no further complaints, is the best approach to determine progression of cognitive problems.
Few crises like the current COVID-19 pandemic can better remind us of the importance of the place of medicine in society. Many states have encouraged retired physicians to contribute their knowledge and expertise, putting themselves in particular risk because of their age. It is a good time to be reminded that we owe them significant respect and care when deciding to remove their license. We are encouraged by the diligent efforts of medical boards in supervising our colleagues but warn against zealot evaluators who use this opportunity to force physicians into retirement. We also encourage medical boards to expand their tools and approaches when facing such cases, as mislabeled cognitive diagnoses can be an easy scapegoat of a poor understanding of the more important psychological and biological factors in the evaluation.

HFNC more comfortable for posthypercapnic patients with COPD
Following invasive ventilation for severe hypercapnic respiratory failure, patients with chronic obstructive pulmonary disease had similar levels of treatment failure if they received high-flow nasal cannula oxygen therapy or noninvasive ventilation, recent research in Critical Care has suggested.
However, for patients with COPD weaned off invasive ventilation, high-flow nasal cannula (HFNC) oxygen therapy was “more comfortable and better tolerated,” compared with noninvasive ventilation (NIV). In addition, “airway care interventions and the incidence of nasofacial skin breakdown associated with HFNC were significantly lower than in NIV,” according to Dingyu Tan of the Clinical Medical College of Yangzhou (China) University, Northern Jiangsu People’s Hospital, and colleagues. “HFNC appears to be an effective means of respiratory support for COPD patients extubated after severe hypercapnic respiratory failure,” they said.
The investigators screened patients with COPD and hypercapnic respiratory failure for enrollment, including those who met Global Initiative for Obstructive Lung Disease (GOLD) criteria, were 85 years old or younger and caring for themselves, had bronchopulmonary infection–induced respiratory failure, and had achieved pulmonary infection control criteria. Exclusion criteria were:
- Patients under age 18 years.
- Presence of oral or facial trauma.
- Poor sputum excretion ability.
- Hemodynamic instability that would contraindicate use of NIV.
- Poor cough during PIC window.
- Poor short-term prognosis.
- Failure of the heart, brain, liver or kidney.
- Patients who could not consent to treatment.
Patients were determined to have failed treatment if they returned to invasive mechanical ventilation or switched from one treatment to another (HFNC to NIV or NIV to HFNC). Investigators also performed an arterial blood gas analysis, recorded the number of duration of airway care interventions, and monitored vital signs at 1 hour, 24 hours, and 48 hours after extubation as secondary analyses.
Overall, 44 patients randomized to receive HFNC and 42 patients randomized for NIV were available for analysis. The investigators found 22.7% of patients in the HFNC group and 28.6% in the NIV group experienced treatment failure (risk difference, –5.8%; 95% confidence interval, −23.8 to 12.4%; P = .535), with patients in the HFNC group experiencing a significantly lower level of treatment intolerance, compared with patients in the NIV group (risk difference, –50.0%; 95% CI, −74.6 to −12.9%; P = .015). There were no significant differences between either group regarding intubation (−0.65%; 95% CI, −16.01 to 14.46%), while rate of switching treatments was lower in the HFNC group but not significant (−5.2%; 95% CI, −19.82 to 9.05%).
Patients in both the HFNC and NIV groups had faster mean respiratory rates 1 hour after extubation (P < .050). After 24 hours, the NIV group had higher-than-baseline respiratory rates, compared with the HFNC group, which had returned to normal (20 vs. 24.5 breaths per minute; P < .050). Both groups had returned to baseline by 48 hours after extubation. At 1 hour after extubation, patients in the HFNC group had lower PaO2/FiO2 (P < .050) and pH values (P < .050), and higher PaCO2 values (P less than .050), compared with baseline. There were no statistically significant differences in PaO2/FiO2, pH, and PaCO2 values in either group at 24 hours or 48 hours after extubation.
Daily airway care interventions were significantly higher on average in the NIV group, compared with the HFNC group (7 vs. 6; P = .0006), and the HFNC group also had significantly better comfort scores (7 vs. 5; P < .001) as measured by a modified visual analog scale, as well as incidence of nasal and facial skin breakdown (0 vs. 9.6%; P = .027), compared with the NIV group.
Results difficult to apply to North American patients
David L. Bowton, MD, FCCP, a professor specializing in critical care at Wake Forest University, Winston-Salem, N.C., said in an interview the results of this trial may not be applicable for patients with infection-related respiratory failure and COPD in North America “due to the differences in common weaning practices between North America and China.”
For example, the trial used the pulmonary infection control (PIC) window criteria for extubation, which requires a significant decrease in radiographic infiltrates, improvement in quality and quantity of sputum, normalizing of leukocyte count, a synchronized intermittent mandatory ventilation (SIMV) rate of 10-12 breaths per minute, and pressure support less than 10-12 cm/H2O (Int J Chron Obstruct Pulmon Dis. 2017;12:1255-67).
“The process used to achieve these measures is not standardized. In North America, daily awakening and screening for spontaneous breathing trials would be usual, but this was not reported in the current trial,” he explained.
Differences in patient population also make the application of the results difficult, Dr. Bowton said. “Only 60% of the patients had spirometrically confirmed COPD and fewer than half were on at least dual inhaled therapy prior to hospitalization with only one-third taking beta agonists or anticholinergic agents,” he noted. “The cause of respiratory failure was infectious, requiring an infiltrate on chest radiograph; thus, patients with hypercarbic respiratory failure without a new infiltrate were excluded from the study. On average, patients were hypercarbic, yet alkalemic at the time of extubation; the PaCO2 and pH at the time of intubation were not reported.
“This study suggests that in some patients with COPD and respiratory failure requiring invasive mechanical ventilation, HFO [high-flow oxygen] may be better tolerated and equally effective as NIPPV [noninvasive positive-pressure ventilation] at mitigating the need for reintubation following extubation. In this patient population where hypoxemia prior to extubation was not severe, the mechanisms by which HFO is beneficial remain speculative,” he said.
This study was funded by the Rui E special fund for emergency medicine research and the Yangzhou Science and Technology Development Plan. The authors report no relevant conflicts of interest. Dr. Bowton reports no relevant conflicts of interest.

Patients were determined to have failed treatment if they returned to invasive mechanical ventilation or switched from one treatment to another (HFNC to NIV or NIV to HFNC). Investigators also performed an arterial blood gas analysis, recorded the number of duration of airway care interventions, and monitored vital signs at 1 hour, 24 hours, and 48 hours after extubation as secondary analyses.
Overall, 44 patients randomized to receive HFNC and 42 patients randomized for NIV were available for analysis. The investigators found 22.7% of patients in the HFNC group and 28.6% in the NIV group experienced treatment failure (risk difference, –5.8%; 95% confidence interval, −23.8 to 12.4%; P = .535), with patients in the HFNC group experiencing a significantly lower level of treatment intolerance, compared with patients in the NIV group (risk difference, –50.0%; 95% CI, −74.6 to −12.9%; P = .015). There were no significant differences between either group regarding intubation (−0.65%; 95% CI, −16.01 to 14.46%), while rate of switching treatments was lower in the HFNC group but not significant (−5.2%; 95% CI, −19.82 to 9.05%).
Patients in both the HFNC and NIV groups had faster mean respiratory rates 1 hour after extubation (P < .050). After 24 hours, the NIV group had higher-than-baseline respiratory rates, compared with the HFNC group, which had returned to normal (20 vs. 24.5 breaths per minute; P < .050). Both groups had returned to baseline by 48 hours after extubation. At 1 hour after extubation, patients in the HFNC group had lower PaO2/FiO2 (P < .050) and pH values (P < .050), and higher PaCO2 values (P less than .050), compared with baseline. There were no statistically significant differences in PaO2/FiO2, pH, and PaCO2 values in either group at 24 hours or 48 hours after extubation.
Daily airway care interventions were significantly higher on average in the NIV group, compared with the HFNC group (7 vs. 6; P = .0006), and the HFNC group also had significantly better comfort scores (7 vs. 5; P < .001) as measured by a modified visual analog scale, as well as incidence of nasal and facial skin breakdown (0 vs. 9.6%; P = .027), compared with the NIV group.
Results difficult to apply to North American patients
David L. Bowton, MD, FCCP, a professor specializing in critical care at Wake Forest University, Winston-Salem, N.C., said in an interview the results of this trial may not be applicable for patients with infection-related respiratory failure and COPD in North America “due to the differences in common weaning practices between North America and China.”
For example, the trial used the pulmonary infection control (PIC) window criteria for extubation, which requires a significant decrease in radiographic infiltrates, improvement in quality and quantity of sputum, normalizing of leukocyte count, a synchronized intermittent mandatory ventilation (SIMV) rate of 10-12 breaths per minute, and pressure support less than 10-12 cm/H2O (Int J Chron Obstruct Pulmon Dis. 2017;12:1255-67).
“The process used to achieve these measures is not standardized. In North America, daily awakening and screening for spontaneous breathing trials would be usual, but this was not reported in the current trial,” he explained.
Differences in patient population also make the application of the results difficult, Dr. Bowton said. “Only 60% of the patients had spirometrically confirmed COPD and fewer than half were on at least dual inhaled therapy prior to hospitalization with only one-third taking beta agonists or anticholinergic agents,” he noted. “The cause of respiratory failure was infectious, requiring an infiltrate on chest radiograph; thus, patients with hypercarbic respiratory failure without a new infiltrate were excluded from the study. On average, patients were hypercarbic, yet alkalemic at the time of extubation; the PaCO2 and pH at the time of intubation were not reported.
“This study suggests that in some patients with COPD and respiratory failure requiring invasive mechanical ventilation, HFO [high-flow oxygen] may be better tolerated and equally effective as NIPPV [noninvasive positive-pressure ventilation] at mitigating the need for reintubation following extubation. In this patient population where hypoxemia prior to extubation was not severe, the mechanisms by which HFO is beneficial remain speculative,” he said.
This study was funded by the Rui E special fund for emergency medicine research and the Yangzhou Science and Technology Development Plan. The authors report no relevant conflicts of interest. Dr. Bowton reports no relevant conflicts of interest.

Following invasive ventilation for severe hypercapnic respiratory failure, patients with chronic obstructive pulmonary disease had similar levels of treatment failure if they received high-flow nasal cannula oxygen therapy or noninvasive ventilation, recent research in Critical Care has suggested.
However, for patients with COPD weaned off invasive ventilation, high-flow nasal cannula (HFNC) oxygen therapy was “more comfortable and better tolerated,” compared with noninvasive ventilation (NIV). In addition, “airway care interventions and the incidence of nasofacial skin breakdown associated with HFNC were significantly lower than in NIV,” according to Dingyu Tan of the Clinical Medical College of Yangzhou (China) University, Northern Jiangsu People’s Hospital, and colleagues. “HFNC appears to be an effective means of respiratory support for COPD patients extubated after severe hypercapnic respiratory failure,” they said.
The investigators screened patients with COPD and hypercapnic respiratory failure for enrollment, including those who met Global Initiative for Obstructive Lung Disease (GOLD) criteria, were 85 years old or younger and caring for themselves, had bronchopulmonary infection–induced respiratory failure, and had achieved pulmonary infection control criteria. Exclusion criteria were:
- Patients under age 18 years.
- Presence of oral or facial trauma.
- Poor sputum excretion ability.
- Hemodynamic instability that would contraindicate use of NIV.
- Poor cough during PIC window.
- Poor short-term prognosis.
- Failure of the heart, brain, liver or kidney.
- Patients who could not consent to treatment.
