Obesity, atopic dermatitis, psychiatric disease, and arthritis are the most common comorbidities among infants, children, and adolescents with psoriasis, while predictors of moderate to severe disease include morphology, non-White race, and culture-confirmed infection.

Those are among the key findings from a retrospective analysis of pediatric psoriasis patients who were seen at the University of California, San Francisco, over a 24-year period.

“Overall, our data support prior findings of age- and sex-based differences in location and morphology and presents new information demonstrating associations with severity,” presenting study author Carmel Aghdasi said during the annual meeting of the Society for Pediatric Dermatology. “We provide evidence of the increased use of systemic and biologic therapies over time, an important step in ensuring pediatric patients are adequately treated.”

To characterize the demographics, clinical features, comorbidities, and treatments, and to determine predictors of severity and changes in treatment patterns over 2 decades in a large cohort of pediatric psoriasis patients, Ms. Aghdasi, a 4th-year medical student at the University of California, San Francisco, and colleagues retrospectively evaluated the records of 754 pediatric patients up to 18 years of age who were seen at UCSF for psoriasis from 1997 to 2021. They collected demographic, clinical, familial, comorbidity, and treatment data and divided the cohort into two groups by date of last visit.

Group 1 consisted of 332 patients whose last visit was between 2001 and 2011, while the second group included 422 patients whose last visit was between 2012 and 2021. The researchers also divided the cohort into three age groups: infants (0-2 years of age), children (3-12 years of age), and adolescents (13-18 years of age).

Slightly more than half of the patients (55%) were female and 67% presented between ages 3 and 12. (Seventy-four patients were in the youngest category, 0-2 years, when they presented.) The average age of disease onset was 7 years, the average age at presentation to pediatric dermatology was 8.8 years, and 37% of the total cohort were overweight or obese. The top four comorbidities were being overweight or obese (37%), followed by atopic dermatitis (19%), psychiatric disease (7%), and arthritis (4%).

Plaque was the most common morphology (56%), while the most common sites of involvement were the head and neck (69%), extremities (61%), and trunk (44%). About half of the cohort (51%) had mild disease, 15% had culture-confirmed infections (9% had Streptococcal infections), and 66% of patients reported itch as a symptom.

The researchers observed that inverse psoriasis was significantly more common in infants and decreased with age. Anogenital involvement was more common in males and in those aged 0-2, while head and neck involvement was more common in females. Nail involvement was more common in childhood.

Topical therapy was the most common treatment overall and by far the most common among those in the 0-2 age category. “Overall, phototherapy was used in childhood and adolescents but almost never in infancy,” Ms. Aghdasi said. “Looking at changes in systemic treatment over time, conventional systemic use increased in infants and children and decreased in adolescents. Biologic use increased in all ages, most notably in children aged 3-12 years old.”

Multivariate regression analyses revealed that the following independent variables predicted moderate to severe psoriasis: adolescent age (adjusted odds ratio, 1.9; P = .03), guttate morphology (aOR, 2.2; P = .006), plaque and guttate morphology (aOR, 7.6; P less than .001), pustular or erythrodermic morphology (aOR, 5; P = .003), culture-confirmed infection (aOR, 2; P = .007), Black race (aOR, 3.3; P = .007), Asian race (aOR, 1.8; P = .04, and Hispanic race (aOR, 1.9; P = .03).

“Further analysis is needed to elucidate the influence of race on severity and of the clinical utility of infection as a marker of severity,” Ms. Aghdasi said. “Interestingly, we did not find that obesity was a marker of severity in our cohort.”

In an interview, senior study author Kelly M. Cordoro, MD, professor of dermatology and pediatrics at UCSF, noted that this finding conflicts with prior studies showing an association between obesity and severe psoriasis in children.

To the Editor:

A 56-year-old man with a history of stage IV metastatic penile squamous cell carcinoma treated with penectomy and chemotherapy with 5-fluorouracil and cisplatin presented with several painful ulcerations in the groin, abdomen, and thighs. The lesions initially appeared in the groin and were treated as bacterial abscesses with antibiotics. Over the next few weeks, new lesions appeared on the abdomen and thighs. An additional cycle of chemotherapy led to a reduction in number; however, they again increased within a few weeks. Medications included enoxaparin followed by 3 weeks of warfarin use due to a right leg deep vein thrombosis.

Physical examination revealed multiple 1- to 4-cm, firm, ulcerated nodules on the bilateral inguinal folds, abdomen, and upper thighs, as well as areas of livedo racemosa and noninflammatory retiform purpura with central ulceration (Figures 1 and 2). This retiform purpura was both perilesional and in areas without ulcerations. Laboratory values included the following: sodium, 127 mmol/L (reference range, 136–145 mmol/L); prothrombin time, 16.1 seconds (reference range, 11–15 seconds); white blood cell count, 20.69×10⁹/L (reference range, 4.5–11.0×10⁹/L) with 87% neutrophils (reference range, 54%–62%); hemoglobin, 6.1 g/dL (reference range, 13.5–17.5 g/dL); hematocrit, 18.8% (reference range, 41%–53%); platelets, 474×10⁹/L (reference range, 150–400×10⁹/L); D-dimer, 0.77 mg/L (reference range, ≤0.50 mg/L); fibrinogen, 489 mg/dL (reference range, 150–400 mg/dL); prior urine culture positive for Pseudomonas aeruginosa. He was negative for hepatitis B and hepatitis C viruses as well as HIV, and the lesions were not clinically consistent with herpes simplex virus, as they were not scalloped or circinate. Punch biopsies were obtained from a nodule on the left leg and a purpuric patch on the right leg.

Ischemic cutaneous lesions less commonly occur in the setting of malignancy and can be the result of both direct and indirect systemic effects from the cancer. Malignancies are known to directly trigger vasculopathies in other organs, most commonly the lungs, through 2 primary mechanisms. First, in carcinomatous arteriopathy, metastatic cells promote fibrocellular intimal proliferation of small pulmonary arteries and arterioles leading to stenosis, thrombosis, and obliteration. This mechanism has been described in pulmonary thrombotic microangiopathy secondary to lung carcinoma.⁴ This pathophysiology likely is also what underlies paraneoplastic acral vascular syndromes, which culminate in digital ischemia. Hypothesized mechanisms for this ischemia also range from vasospasm to thromboembolism.⁵ Secondly, in vasculitis carcinomatosa, metastatic tumor cells damage or block vessel walls, resulting in end-organ ischemia. Vasculitis carcinomatosa is a well-known phenomenon in angiocentric and intravascular lymphoid malignancies (typically of B-T or natural killer/T-cell origin) but also has been reported in a case of gastric adenocarcinoma with arterial invasion.⁶ This process is different than carcinoma telangiectoides where malignant cells may be present in the vasculature on histopathology but not trigger thrombosis and ischemic skin necrosis.

Systemic coagulopathies such as disseminated intravascular coagulation (DIC), thrombotic thrombocytopenia purpura, and catastrophic antiphospholipid antibody syndrome can occur in the setting of malignancies.⁷ Clinically, all may present with livedo racemosa, noninflammatory retiform purpura, and widespread skin necrosis. In adult patients, purpura fulminans most often is seen in the setting of sepsis and DIC, with accompanying evidence of microangiopathy.⁸ Catastrophic antiphospholipid antibody syndrome can be triggered by malignancy and is characterized by central nervous system, renal, pulmonary, and gastrointestinal complications. Skin involvement such as ulcers, livedo reticularis, and gangrene have been reported.⁹ Other causes of thrombotic vasculopathy include warfarin necrosis, heparin-induced thrombotic thrombocytopenia, calciphylaxis, and angioinvasive infections.⁸ Warfarin necrosis and heparin-induced thrombotic thrombocytopenia typically present days after initiating therapy with the respective medication. Calciphylaxis typically occurs in patients on dialysis, though it may occur in nonuremic patients including those with malignancy.⁸ Patients with malignancies on chemotherapy can become neutropenic and are at risk for ecthyma gangrenosum due to P aeruginosa and other gram-negative rods, Staphylococcus aureus, and angioinvasive fungi.¹⁰

Based on clinical, histopathological, and laboratory data, we favored a diagnosis of cutaneous carcinomatous arteriopathy. Vasculitis carcinomatosa was a possibility despite the lack of vasculotropism on histopathology, which may have been due to biopsy site selection. Systemic coagulopathies such as DIC, thrombotic thrombocytopenia purpura, and catastrophic antiphospholipid antibody syndrome were unlikely, as the ischemic skin lesions and livedo racemosa were limited to areas adjacent to cutaneous metastases, and the patient lacked other common multiorgan manifestations or laboratory findings. Although our patient was on warfarin, he was on a stable dose for weeks and histopathologic features of subcutaneous thrombosis were not seen. The biopsy also was not consistent with calciphylaxis. Ecthyma gangrenosum was unlikely given the lack of organisms on histopathology and negative skin and blood cultures. Although additional laboratory testing in this patient may have included cryoglobulins and cryofibrinogens, both entities were unlikely due to a lack of ischemic acral lesions.

In conclusion, we present a case of localized thrombotic vasculopathy that likely was secondary to cutaneous carcinomatous arteriopathy in the setting of cutaneous metastatic penile squamous cell carcinoma. The differential diagnosis of retiform purpura, livedo racemosa, and other signs of cutaneous ischemia in patients with metastatic cancer is broad and can be the result of both direct and indirect systemic effects from the cancer. Appropriate workup in these cases should include skin biopsies for histopathology and culture, medication review, and laboratory evaluation for systemic coagulopathies.

Skin involvement such as ulcers, livedo reticularis, and gangrene have been reported.⁹ Other causes of thrombotic vasculopathy include warfarin necrosis, heparin-induced thrombotic thrombocytopenia, calciphylaxis, and angioinvasive infections.⁸ Warfarin necrosis and heparin-induced thrombotic thrombocytopenia typically present days after initiating therapy with the respective medication. Calciphylaxis typically occurs in patients on dialysis, though it may occur in nonuremic patients including those with malignancy.⁸ Patients with malignancies on chemotherapy can become neutropenic and are at risk for ecthyma gangrenosum due to P aeruginosa and other gram-negative rods, Staphylococcus aureus, and angioinvasive fungi.¹⁰

Based on clinical, histopathological, and laboratory data, we favored a diagnosis of cutaneous carcinomatous arteriopathy. Vasculitis carcinomatosa was a possibility despite the lack of vasculotropism on histopathology, which may have been due to biopsy site selection. Systemic coagulopathies such as DIC, thrombotic thrombocytopenia purpura, and catastrophic antiphospholipid antibody syndrome were unlikely, as the ischemic skin lesions and livedo racemosa were limited to areas adjacent to cutaneous metastases, and the patient lacked other common multiorgan manifestations or laboratory findings. Although our patient was on warfarin, he was on a stable dose for weeks and histopathologic features of subcutaneous thrombosis were not seen. The biopsy also was not consistent with calciphylaxis. Ecthyma gangrenosum was unlikely given the lack of organisms on histopathology and negative skin and blood cultures. Although additional laboratory testing in this patient may have included cryoglobulins and cryofibrinogens, both entities were unlikely due to a lack of ischemic acral lesions.

In conclusion, we present a case of localized thrombotic vasculopathy that likely was secondary to cutaneous carcinomatous arteriopathy in the setting of cutaneous metastatic penile squamous cell carcinoma. The differential diagnosis of retiform purpura, livedo racemosa, and other signs of cutaneous ischemia in patients with metastatic cancer is broad and can be the result of both direct and indirect systemic effects from the cancer. Appropriate workup in these cases should include skin biopsies for histopathology and culture, medication review, and laboratory evaluation for systemic coagulopathies.

To the Editor:

A 56-year-old man with a history of stage IV metastatic penile squamous cell carcinoma treated with penectomy and chemotherapy with 5-fluorouracil and cisplatin presented with several painful ulcerations in the groin, abdomen, and thighs. The lesions initially appeared in the groin and were treated as bacterial abscesses with antibiotics. Over the next few weeks, new lesions appeared on the abdomen and thighs. An additional cycle of chemotherapy led to a reduction in number; however, they again increased within a few weeks. Medications included enoxaparin followed by 3 weeks of warfarin use due to a right leg deep vein thrombosis.

Physical examination revealed multiple 1- to 4-cm, firm, ulcerated nodules on the bilateral inguinal folds, abdomen, and upper thighs, as well as areas of livedo racemosa and noninflammatory retiform purpura with central ulceration (Figures 1 and 2). This retiform purpura was both perilesional and in areas without ulcerations. Laboratory values included the following: sodium, 127 mmol/L (reference range, 136–145 mmol/L); prothrombin time, 16.1 seconds (reference range, 11–15 seconds); white blood cell count, 20.69×10⁹/L (reference range, 4.5–11.0×10⁹/L) with 87% neutrophils (reference range, 54%–62%); hemoglobin, 6.1 g/dL (reference range, 13.5–17.5 g/dL); hematocrit, 18.8% (reference range, 41%–53%); platelets, 474×10⁹/L (reference range, 150–400×10⁹/L); D-dimer, 0.77 mg/L (reference range, ≤0.50 mg/L); fibrinogen, 489 mg/dL (reference range, 150–400 mg/dL); prior urine culture positive for Pseudomonas aeruginosa. He was negative for hepatitis B and hepatitis C viruses as well as HIV, and the lesions were not clinically consistent with herpes simplex virus, as they were not scalloped or circinate. Punch biopsies were obtained from a nodule on the left leg and a purpuric patch on the right leg.

Ischemic cutaneous lesions less commonly occur in the setting of malignancy and can be the result of both direct and indirect systemic effects from the cancer. Malignancies are known to directly trigger vasculopathies in other organs, most commonly the lungs, through 2 primary mechanisms. First, in carcinomatous arteriopathy, metastatic cells promote fibrocellular intimal proliferation of small pulmonary arteries and arterioles leading to stenosis, thrombosis, and obliteration. This mechanism has been described in pulmonary thrombotic microangiopathy secondary to lung carcinoma.⁴ This pathophysiology likely is also what underlies paraneoplastic acral vascular syndromes, which culminate in digital ischemia. Hypothesized mechanisms for this ischemia also range from vasospasm to thromboembolism.⁵ Secondly, in vasculitis carcinomatosa, metastatic tumor cells damage or block vessel walls, resulting in end-organ ischemia. Vasculitis carcinomatosa is a well-known phenomenon in angiocentric and intravascular lymphoid malignancies (typically of B-T or natural killer/T-cell origin) but also has been reported in a case of gastric adenocarcinoma with arterial invasion.⁶ This process is different than carcinoma telangiectoides where malignant cells may be present in the vasculature on histopathology but not trigger thrombosis and ischemic skin necrosis.

Systemic coagulopathies such as disseminated intravascular coagulation (DIC), thrombotic thrombocytopenia purpura, and catastrophic antiphospholipid antibody syndrome can occur in the setting of malignancies.⁷ Clinically, all may present with livedo racemosa, noninflammatory retiform purpura, and widespread skin necrosis.

Intraosseous (IO) access can afford a lifesaving means of vascular access in emergency settings, as it allows for the administration of large volumes of fluids, blood products, and medications at high flow rates directly into the highly vascularized osseous medullary cavity.¹ Fortunately, the complication rate with this resuscitative effort is low, with many reports demonstrating complication rates of less than 1%.² The most commonly reported complications include fluid extravasation, osteomyelitis, traumatic bone fracture, and epiphyseal plate damage.^1-3 Although compartment syndrome and skin necrosis have been reported,^4,5 there is no comprehensive list of sequelae resulting from fluid extravasation in the literature, and there are no known studies examining the incidence and types of cutaneous complications. In this study, we sought to evaluate the dermatologic impacts of this procedure.

Methods

We performed a retrospective chart review approved by the institutional review board at a large metropolitan level I trauma center in the Midwestern United States spanning 18 consecutive months to identify all patients who underwent IO line placement, either en route to or upon arrival at the trauma center. The electronic medical records of 113 patients (age range, 10 days–94 years) were identified using either an automated natural language look-up program with keywords including intraosseous access and IO or a Current Procedural Terminology code 36680. Data including patient age, reason for IO insertion, anatomic location of the IO, and complications secondary to IO line placement were recorded.

Results

We identified an overall complication rate of 2.7% (3/113), with only 1 patient showing isolated cutaneous complications from IO line placement. The complications in the first 2 patients included compartment syndrome following IO line placement in the right tibia and needle breakage during IO line placement. The third patient, a 30-year-old heart transplant recipient, developed tense bullae on the left leg 5 days after a resuscitative effort required IO access through the bilateral tibiae. The patient had received vasopressors as well as 750 mL of normal saline through these access points. Two days after resuscitation, she developed an enlarging ecchymosis around the left IO access point. On day 5, cutaneous findings included 2 large firm bullae on a purpuric base overlying the left proximal tibia and patella (Figure 1). After an ultrasound revealed no connection to the underlying joint space, the bullae were incised and drained for patient comfort, as she reported pain and undue pressure at the knee joint on initial dermatologic consultation. These symptoms abated after the procedure. Cultures of bullous fluid were negative for infection. Histopathologic examination revealed a subepidermal split with underlying minimal mixed inflammation, favoring the diagnosis of traumatic bullae.

At a scheduled 7-month dermatology follow-up, the wound bed appeared to be healing well with surrounding scarring with no residual bleeding or drainage (Figure 2) despite the patient reporting a protracted course of wound healing requiring debridement due to eschar formation and multiple follow-up appointments with the wound care service.

Comment

The most commonly reported complications with IO line placement result from fluid infiltration of the subcutaneous tissue secondary to catheter misplacement.^1,3 Extravasated fluid may lead to tissue damage, compartment syndrome, and even tissue necrosis in some cases.^1,4,5 Localized cellulitis and the formation of subcutaneous abscesses also have been reported, albeit rarely.^3,5

In our retrospective cohort review, we identified an additional potential complication of IO line placement that has not been widely reported—development of large traumatic bullae. It is most likely that this patient’s IO catheter became dislodged, resulting in extravasation of fluids into the dermal and subcutaneous tissues.

Our findings support the previously noted complication rate of less than 1% following IO line placement, with an overall complication rate of 2.7% that included only 1 patient with a cutaneous complication.² Given this low incidence, providers may not be used to recognizing such complications, leading to delayed or incorrect diagnosis of these entities. While there are certain conditions in which IO insertion is contraindicated, including severe bone diseases (eg, osteogenesis imperfecta, osteomyelitis), overlying cellulitis, and bone fracture, these conditions are rare and can be avoided in most cases by use of an alternative site for needle insertion.² Due to the widespread utility of this tool and its few contraindications, its use in hospitalized patients is rapidly increasing, necessitating a need for quick recognition of potential complications.

From previous data on the incidence of traumatic blisters with underlying bone fractures, there are several identifiable risk factors that could be extended to patients at high risk for developing cutaneous IO complications secondary to the trauma associated with needle insertion,⁶ including wound-healing impairments in patients with fragile lymphatics, peripheral vascular disease, diabetes, or collagen vascular diseases (eg, lupus, rheumatoid arthritis, Sjögren syndrome). Patients with these conditions should be closely monitored for the development of bullae.⁶ While the patient we highlighted in our study did not have a history of such conditions, her history of cardiac disease, recent resuscitation attempts, and immunosuppression certainly could have contributed to suboptimal tissue agility and repair after IO line placement.

Conclusion

Intraosseous access is a safe, effective, and reliable option for vascular access in both pediatric and adult populations that is widely used in both prehospital (ie, paramedic administered) and hospital settings, including intensive care units, emergency departments, and any acute situation where rapid vascular access is necessary. This retrospective chart review examining the incidence and types of cutaneous complications associated with IO line placement at a level I trauma center revealed a total complication rate similar to those reported in previous studies and also highlighted a unique postprocedural cutaneous finding of traumatic bullae. Although no unified management recommendations currently exist, providers should consider this complication in the differential for hospitalized patients with large, atypical, asymmetric bullae in the absence of an alternative explanation for such skin findings.

Most of us are familiar with the good news: In recent weeks, rates of COVID-19 infection and death have plummeted in California, falling to levels not seen since the early days of the pandemic. The average number of new COVID infections reported each day dropped by an astounding 98% from December to June, according to figures from the California Department of Public Health.

And bolstering that trend, nearly 70% of Californians 12 and older are partially or fully vaccinated.

But state health officials are still reporting nearly 1,000 new COVID cases and more than 2 dozen COVID-related deaths per day. So, where does COVID continue to simmer in California? And why?

An analysis of state data shows some clear patterns at this stage of the pandemic: As vaccination rates rose across the state, the overall numbers of cases and deaths plunged. But within that broader trend are pronounced regional discrepancies. Counties with relatively low rates of vaccination reported much higher rates of COVID infections and deaths in May and June than counties with high vaccination rates.

There were about 182 new COVID infections per 100,000 residents from May 1 to June 18 in California counties where fewer than half of residents age 12 and older had received at least one vaccine dose, CDPH data show. By comparison, there were about 102 COVID infections per 100,000 residents in counties where more than two-thirds of residents 12 and up had gotten at least one dose.

“If you live in an area that has low vaccination rates and you have a few people who start to develop a disease, it’s going to spread quickly among those who aren’t vaccinated,” said Rita Burke, PhD, assistant professor of clinical preventive medicine at the University of Southern California, Los Angeles. Dr. Burke noted that the highly contagious Delta variant of the coronavirus now circulating in California amplifies the threat of serious outbreaks in areas with low vaccination rates.

The regional discrepancies in COVID-related deaths are also striking. There were about 3.2 COVID-related deaths per 100,000 residents from May 1 to June 18 in counties where first-dose vaccination rates were below 50%. That is almost twice as high as the death rate in counties where more than two-thirds of residents had at least one dose.

While the pattern is clear, there are exceptions. A couple of sparsely populated mountain counties with low vaccination rates – Trinity and Mariposa – also had relatively low rates of new infections in May and June. Likewise, a few suburban counties with high vaccination rates – among them Sonoma and Contra Costa – had relatively high rates of new infections.

“There are three things that are going on,” said George Rutherford, MD, a professor of epidemiology and biostatistics at the University of California, San Francisco. “One is the vaccine – very important, but not the whole story. One is naturally acquired immunity, which is huge in some places.” A third, he said, is people still managing to evade infection, whether by taking precautions or simply by living in areas with few infections.

As of June 18, about 67% of Californians age 12 and older had received at least one dose of COVID vaccine, according to the state health department. But that masks a wide variance among the state’s 58 counties. In 14 counties, for example, fewer than half of residents 12 and older had received a shot. In 19 counties, more than two-thirds had.

The counties with low vaccination rates are largely rugged and rural. Nearly all are politically conservative. In January, about 6% of the state’s COVID infections were in the 23 counties where a majority of voters cast ballots for President Donald Trump in November. By May and June, that figure had risen to 11%.

While surveys indicate politics plays a role in vaccine hesitancy in many communities, access also remains an issue in many of California’s rural outposts. It can be hard, or at least inconvenient, for people who live far from the nearest medical facility to get two shots a month apart.

“If you have to drive 30 minutes out to the nearest vaccination site, you may not be as inclined to do that versus if it’s 5 minutes from your house,” Dr. Burke said. “And so we, the public health community, recognize that and have really made a concerted effort in order to eliminate or alleviate that access issue.”

Many of the counties with low vaccination rates had relatively low infection rates in the early months of the pandemic, largely thanks to their remoteness. But, as COVID reaches those communities, that lack of prior exposure and acquired immunity magnifies their vulnerability, Dr. Rutherford said. “We’re going to see cases where people are unvaccinated or where there’s not been a big background level of immunity already.”

As it becomes clearer that new infections will be disproportionately concentrated in areas with low vaccination rates, state officials are working to persuade hesitant Californians to get a vaccine, even introducing a vaccine lottery.

But most persuasive are friends and family members who can help counter the disinformation rampant in some communities, said Lorena Garcia, DrPH, an associate professor of epidemiology at the University of California, Davis. Belittling people for their hesitancy or getting into a political argument likely won’t work.

When talking to her own skeptical relatives, Dr. Garcia avoided politics: “I just explained any questions that they had.”

“Vaccines are a good part of our life,” she said. “It’s something that we’ve done since we were babies. So, it’s just something we’re going to do again.”

Many of the counties with low vaccination rates had relatively low infection rates in the early months of the pandemic, largely thanks to their remoteness. But, as COVID reaches those communities, that lack of prior exposure and acquired immunity magnifies their vulnerability, Dr. Rutherford said. “We’re going to see cases where people are unvaccinated or where there’s not been a big background level of immunity already.”

As it becomes clearer that new infections will be disproportionately concentrated in areas with low vaccination rates, state officials are working to persuade hesitant Californians to get a vaccine, even introducing a vaccine lottery.

But most persuasive are friends and family members who can help counter the disinformation rampant in some communities, said Lorena Garcia, DrPH, an associate professor of epidemiology at the University of California, Davis. Belittling people for their hesitancy or getting into a political argument likely won’t work.

When talking to her own skeptical relatives, Dr. Garcia avoided politics: “I just explained any questions that they had.”

“Vaccines are a good part of our life,” she said. “It’s something that we’ve done since we were babies. So, it’s just something we’re going to do again.”

Most of us are familiar with the good news: In recent weeks, rates of COVID-19 infection and death have plummeted in California, falling to levels not seen since the early days of the pandemic. The average number of new COVID infections reported each day dropped by an astounding 98% from December to June, according to figures from the California Department of Public Health.

And bolstering that trend, nearly 70% of Californians 12 and older are partially or fully vaccinated.

But state health officials are still reporting nearly 1,000 new COVID cases and more than 2 dozen COVID-related deaths per day. So, where does COVID continue to simmer in California? And why?

An analysis of state data shows some clear patterns at this stage of the pandemic: As vaccination rates rose across the state, the overall numbers of cases and deaths plunged. But within that broader trend are pronounced regional discrepancies. Counties with relatively low rates of vaccination reported much higher rates of COVID infections and deaths in May and June than counties with high vaccination rates.

There were about 182 new COVID infections per 100,000 residents from May 1 to June 18 in California counties where fewer than half of residents age 12 and older had received at least one vaccine dose, CDPH data show. By comparison, there were about 102 COVID infections per 100,000 residents in counties where more than two-thirds of residents 12 and up had gotten at least one dose.

“If you live in an area that has low vaccination rates and you have a few people who start to develop a disease, it’s going to spread quickly among those who aren’t vaccinated,” said Rita Burke, PhD, assistant professor of clinical preventive medicine at the University of Southern California, Los Angeles. Dr. Burke noted that the highly contagious Delta variant of the coronavirus now circulating in California amplifies the threat of serious outbreaks in areas with low vaccination rates.

The regional discrepancies in COVID-related deaths are also striking. There were about 3.2 COVID-related deaths per 100,000 residents from May 1 to June 18 in counties where first-dose vaccination rates were below 50%. That is almost twice as high as the death rate in counties where more than two-thirds of residents had at least one dose.

While the pattern is clear, there are exceptions. A couple of sparsely populated mountain counties with low vaccination rates – Trinity and Mariposa – also had relatively low rates of new infections in May and June. Likewise, a few suburban counties with high vaccination rates – among them Sonoma and Contra Costa – had relatively high rates of new infections.

“There are three things that are going on,” said George Rutherford, MD, a professor of epidemiology and biostatistics at the University of California, San Francisco. “One is the vaccine – very important, but not the whole story. One is naturally acquired immunity, which is huge in some places.” A third, he said, is people still managing to evade infection, whether by taking precautions or simply by living in areas with few infections.

As of June 18, about 67% of Californians age 12 and older had received at least one dose of COVID vaccine, according to the state health department. But that masks a wide variance among the state’s 58 counties. In 14 counties, for example, fewer than half of residents 12 and older had received a shot. In 19 counties, more than two-thirds had.

The counties with low vaccination rates are largely rugged and rural. Nearly all are politically conservative. In January, about 6% of the state’s COVID infections were in the 23 counties where a majority of voters cast ballots for President Donald Trump in November. By May and June, that figure had risen to 11%.

Sleep-disordered breathing is common in patients with neuromuscular disease and is increasingly addressed with noninvasive ventilation, but its patterns go beyond obstructive sleep apnea (OSA) and include hypoventilation, hypoxemia, central sleep apnea, pseudocentrals, periodic breathing, and Cheyne-Stokes respiration, Gaurav Singh, MD, MPH said at the virtual annual meeting of the Associated Professional Sleep Societies.

The prevalence of sleep-related disordered breathing surpasses 40% in patients diagnosed with neuromuscular disease, but “sleep disordered breathing [in these patients] does not equal obstructive sleep apnea,” said Dr. Singh, staff physician at the Veteran Affairs Palo Alto (Calif.) Health Care System in the section of pulmonary, critical care and sleep medicine, and an affiliated clinical assistant professor at Stanford (Calif.) University.

“The most common sleep-related breathing disorder in neuromuscular disease is probably hypopnea and hypoventilation with the sawtooth pattern of dips in oxygen saturation that occur during REM sleep,” he said. As neuromuscular diseases progress, hypoventilation may occur during non-REM sleep as well.

Evaluation is usually performed with polysomnography and pulmonary function testing, he said, but supplementary testing including serum bicarbonate levels, arterial blood gases, and echocardiography to assess for left ventricular ejection fraction and cardiomyopathy may be useful as well.

While a sleep study is not required per Centers for Medicare & Medicaid coverage criteria for the use of respiratory assist devices in patients with neuromuscular disease, polysomnography is valuable for identifying early nocturnal respiratory impairment before the appearance of symptoms and daytime abnormalities in gas exchange, and is better than home testing for distinguishing different types of events (including pseudocentrals). It also is helpful for determining the appropriate pressures needed for ventilatory support and for assessing the need for a backup rate, Dr. Singh said.

Commonly used types of noninvasive ventilation include bilevel positive airway pressure on the spontaneous/timed or pressure control modes, with or without volume-assured pressure support, he said.

Expiratory positive airway pressure (EPAP) is usually set low initially to help decrease the work of breathing and improve triggering, then titrated up to ensure that upper airway obstructive events are treated. Pressure support (the difference between the inspiratory positive airway pressure and EPAP) is set to achieve target tidal volume and to rest the respiratory muscles. And inspiratory time is set “on the longer end” to achieve maximal target volume and ensure appropriate gas exchange, Dr. Singh said.

Data from randomized controlled trials evaluating the effectiveness of NIV are limited, he said. A study published 15 years ago showed a survival benefit and improvement in quality of life measures in patients with amyotrophic lateral sclerosis (ALS) with normal or moderately impaired bulbar function but not in those with severe bulbar weakness.

Regarding the timing of initiating NIV, a retrospective study published several years ago looked at almost 200 ALS patients and evaluated differences in survival amongst those started earlier with NIV (forced vital capacity ≥80%) and those started later (FVC <80%). At 36 months from diagnosis, mortality was 35% for the early group and 53% for the later group. “Improved survival was driven by benefit in patients with non–bulbar-onset ALS, compared with bulbar-onset disease,” Dr. Singh said.

“This study and several other similar studies seem to indicate that the earlier NIV [noninvasive ventilation] is started in patients with neuromuscular disease, the better in terms of improving survival and other relevant measures such as quality of life,” he said.

Asked about Dr. Singh’s presentation, Michelle Cao, DO, clinical associate professor at Stanford University, said that NIV is an “invaluable tool in the treatment of conditions leading to chronic respiratory failure,” such as neuromuscular disease, and that it’s important to incorporate NIV training for future pulmonary, critical care and sleep physicians. Dr. Cao directs the adult NIV program for the neuromuscular medical program at Stanford Health Care.

Saiprakash B. Venkateshiah, MD, of Emory University, Atlanta, also said in introducing Dr. Singh at the meeting that earlier diagnosis and appropriate NIV therapy “may improve quality of life and possibly even lower survival in certain disorders.”

In addition, he noted that sleep disturbances “may be the earliest sign of muscle weakness in [patients with neuromuscular disease], sometimes being detected before their underlying neuromuscular disease is diagnosed.”

Dr. Singh, Dr. Cao, and Dr. Venkateshiah each reported that they had no potential conflicts of interest.

Just when you start wondering what crazy and potentially dangerous thing people can do to themselves next, comes a crazy and potentially dangerous new trend. The good folks at TikTok have provided patients a new treatment for stuffed up sinuses.

Dangerous? Well, that’s what doctors say, anyway.

“We typically do not recommend putting anything into the nostril for the obvious fact that it could get dislodged or lodged up into the nasal cavity,” Anthony Del Signore, MD, of Mount Sinai Union Square, New York, told TODAY.

“Not only does it have the potential to rot or cause a nasal obstruction, it can induce an episode of sinusitis,” Omid Mehdizadeh, MD, of Providence Saint John’s Health Center, Santa Monica, Calif., explained to Shape.

But who doesn't want to breathe easier and keep blood-sucking vampires at bay?

Seeing faces in random places?

Ever look up at the clouds, at a fast-moving train, or into your morning bowl of cereal and see two eyes, a nose, and a mouth looking back at you? You may shake it off and think you’re imagining something, but it's actually your brain doing what it’s built to do and researchers know why.

The phenomenon is called face pareidolia, and it’s technically an error function of the human brain. Evolution has molded our brains to rapidly identify faces, according to David Alais, PhD, of the University of Sydney, Australia, lead author of the study.

“But the system plays ‘fast and loose’ by applying a crude template of two eyes over a nose and mouth. Lots of things can satisfy that template and thus trigger a face detection response,” he said in a separate statement. But not only are we seeing faces, our brains go one step further and seemingly give those faces feelings.

Corporate dream manipulation

Advertisements are quite literally everywhere. On billboards, in commercials, in videos, in movies; the list goes on and on. Still, at least you can shut your eyes and be mercifully free of corporate interference inside your own head, right? Right?

Early in 2021, Coors launched an ad campaign that seemed to be a b bit of a gimmick, if not a joke. Coors claimed that if people watched an ad before bed, and played an 8-hour soundscape while sleeping, their dreams would be filled with crisp mountains and cold, thirst-quenching beverages. While, the Coors campaign didn’t go viral, someone was paying attention. A group of 35 leading researchers published an open letter on the subject of corporate dream manipulation, in the journal Dream Engineering.

"Multiple marketing studies are openly testing new ways to alter and motivate purchasing behavior through dream and sleep hacking. The commercial, for-profit use of dream incubation is rapidly becoming a reality," wrote the investigators. "As sleep and dream researchers, we are deeply concerned about marketing plans aimed at generating profits at the cost of interfering with our natural nocturnal memory processing."

People have tried to manipulate their dreams for countless years, but only in recent years have scientists attempted to target or manipulate behavior through dreams. In a 2014 study, smokers exposed to tobacco smoke and rotten egg smell while sleeping reduced their cigarette consumption by 30%.

Got breast milk?

As we know, breast milk has endless benefits for newbords and babies, but many things can stand in the way of a mother’s ability to breastfeed. Baby formula has served as a good enough substitute. But now, there might be something that’s even better.

A start-up company called BIOMILQ created a product that could be groundbreaking. Using “breakthrough mammary biotechnology,” BIOMILQ created cell-cultured breast milk.

Catheter ablation appears better than drug therapy for treating atrial fibrillation (AFib) in racial and ethnic minorities, according to a new look at CABANA trial data.

CABANA, which was undertaken to compare catheter ablation and rate-control or rhythm-control drug therapy for AFib, concluded there was no significant difference between the two strategies in improving the trial’s composite primary outcome of death, disabling stroke, serious bleeding, or cardiac arrest.

But a closer look at a subgroup of participants reveals an important difference in outcome among racial and ethnic minorities.

In that group, which made up about 10% of the CABANA study population, catheter ablation was significantly better at treating AFib than was drug therapy, producing roughly a 70% relative reduction in the primary endpoint and all-cause mortality.

The benefit for catheter ablation, which was not seen in the nonminority participants, appeared to be due to worse outcomes with drug therapy, the investigators report in an article published July 5 in the Journal of the American College of Cardiology.

“The study really highlights the importance of trying to secure an inclusive and diverse population in clinical trials,” lead author Kevin L. Thomas, MD, Duke University, Durham, N.C., said in an interview.

“When we focused on the racial and ethnic minorities who were included in CABANA, the findings were different. This was a surprise,” Dr. Thomas said.

“The findings from the secondary analysis of CABANA suggest that racial and ethnic minorities that are treated with drugs compared with ablation do worse,” he said. “If we can validate this in a larger sample of patients and this does in fact turn out to be true, then we would change how we practice medicine. We would have discussions with these populations about the benefits of ablation over drugs, and this would be important information to help guide our practice.”

The investigators analyzed data from 1,280 participants enrolled in the North American arm of CABANA. Of these, 127 (9.9%) were of racial or ethnic minorities, as defined by the National Institutes of Health, and were randomly assigned to receive ablation (n = 62) or drug therapy (n = 65).

Compared with nonminorities, participants of racial and ethnic minorities were younger (median age, 65.5 years, vs. 68.5 years) and were more likely to have NYHA functional class greater than or equal to II symptoms (37.0% vs. 22.0%), hypertension (92.1% vs. 76.8%), and an ejection fraction less than 40% (20.8% vs. 7.1%).

The overall median follow-up was 54.9 months. Among ethnic and minority participants, the median follow-up was 48 months, compared with 55.5 months for the nonminority participants.

Although there was no significant difference in the primary composite endpoint in the main CABANA trial, among racial and ethnic minorities treated with ablation, there was a 68% relative reduction in the trial’s primary endpoint (adjusted hazard ratio, 0.32; 95% confidence interval, 0.13-0.78) and a 72% relative reduction in all-cause mortality (aHR, 0.28; 95% CI, 0.10-0.79).

The 4-year Kaplan-Meier primary event rates were similar in both racial/ethnic minority and nonminority groups that received catheter ablation (12.3% vs. 9.9%).

However, the 4-year event rate was much higher among nonminority participants than among racial and ethnic minorities who received drug therapy (27.4% vs. 9.4%).

The corresponding all-cause 4-year mortality rates were 8.1% and 6.7%, respectively, in the ablation arm and 20.2% and 4.5%, respectively, in the drug arm.

Dr. Thomas and colleagues point out that heart failure in racial and ethnic minorities, particularly Black patients, is typically due to hypertensive heart disease, whereas in non-Hispanic White patients, it is overwhelmingly associated with coronary artery disease. “Our results in CABANA, therefore, raise the possibility that the variations in the prevalence of the heart diseases associated with AFib might account for differences in the benefits observed with ablation therapy.”

Prior data suggest that AFib in the setting of heart failure with either reduced or preserved ejection fraction has substantially better clinical outcomes with ablation versus drug therapy, but most studies either do not report racial/ethnic demographics or enroll very low numbers of minorities, they note.

Andrea M. Russo, MD, a professor of medicine at Rowan University, Camden, New Jersey, asks why drug therapy might result in worse outcomes in racial and ethnic minorities in an accompanying editorial.

“Those who received ablation did better than those who received drugs, and the main reason for that is not that ablation works better in minorities than nonminorities, it’s because drugs are worse in minority patients than they are in nonminority patients. This means that either the way we are using the drugs or the ones that we are using in minority patients are resulting in worse overall outcomes,” Dr. Russo told this news organization.

“The minority patients were younger and yet had more hypertension at baseline. There could be all kinds of factors contributing to their health,” she said.

Dr. Russo agrees with Dr. Thomas on the need to enroll diverse populations in clinical trials.

“Dr. Thomas should be commended. He did a fabulous job of looking at this issue. It’s only 10% of the group, but it is better than what we have had so far, and this is a start,” Dr. Russo said. “It’s bringing recognition to how important it is to make sure that we include underrepresented populations in these trials and also that we offer all appropriate therapies to everyone.”

Catheter ablation appears better than drug therapy for treating atrial fibrillation (AFib) in racial and ethnic minorities, according to a new look at CABANA trial data.

CABANA, which was undertaken to compare catheter ablation and rate-control or rhythm-control drug therapy for AFib, concluded there was no significant difference between the two strategies in improving the trial’s composite primary outcome of death, disabling stroke, serious bleeding, or cardiac arrest.

But a closer look at a subgroup of participants reveals an important difference in outcome among racial and ethnic minorities.

In that group, which made up about 10% of the CABANA study population, catheter ablation was significantly better at treating AFib than was drug therapy, producing roughly a 70% relative reduction in the primary endpoint and all-cause mortality.

The benefit for catheter ablation, which was not seen in the nonminority participants, appeared to be due to worse outcomes with drug therapy, the investigators report in an article published July 5 in the Journal of the American College of Cardiology.

“The study really highlights the importance of trying to secure an inclusive and diverse population in clinical trials,” lead author Kevin L. Thomas, MD, Duke University, Durham, N.C., said in an interview.

“When we focused on the racial and ethnic minorities who were included in CABANA, the findings were different. This was a surprise,” Dr. Thomas said.

“The findings from the secondary analysis of CABANA suggest that racial and ethnic minorities that are treated with drugs compared with ablation do worse,” he said. “If we can validate this in a larger sample of patients and this does in fact turn out to be true, then we would change how we practice medicine. We would have discussions with these populations about the benefits of ablation over drugs, and this would be important information to help guide our practice.”

The investigators analyzed data from 1,280 participants enrolled in the North American arm of CABANA. Of these, 127 (9.9%) were of racial or ethnic minorities, as defined by the National Institutes of Health, and were randomly assigned to receive ablation (n = 62) or drug therapy (n = 65).

Compared with nonminorities, participants of racial and ethnic minorities were younger (median age, 65.5 years, vs. 68.5 years) and were more likely to have NYHA functional class greater than or equal to II symptoms (37.0% vs. 22.0%), hypertension (92.1% vs. 76.8%), and an ejection fraction less than 40% (20.8% vs. 7.1%).

The overall median follow-up was 54.9 months. Among ethnic and minority participants, the median follow-up was 48 months, compared with 55.5 months for the nonminority participants.

Although there was no significant difference in the primary composite endpoint in the main CABANA trial, among racial and ethnic minorities treated with ablation, there was a 68% relative reduction in the trial’s primary endpoint (adjusted hazard ratio, 0.32; 95% confidence interval, 0.13-0.78) and a 72% relative reduction in all-cause mortality (aHR, 0.28; 95% CI, 0.10-0.79).

The 4-year Kaplan-Meier primary event rates were similar in both racial/ethnic minority and nonminority groups that received catheter ablation (12.3% vs. 9.9%).

However, the 4-year event rate was much higher among nonminority participants than among racial and ethnic minorities who received drug therapy (27.4% vs. 9.4%).

The corresponding all-cause 4-year mortality rates were 8.1% and 6.7%, respectively, in the ablation arm and 20.2% and 4.5%, respectively, in the drug arm.

Advanced age by itself can be a reason physicians hold back on prescribing mainstay medications, or fail to uptitrate them per guidelines, to their older patients with heart failure (HF) and reduced ejection fraction (HFrEF), suggests a large cohort study.

About 80% of patients aged 80 years or older were prescribed renin-angiotensin-system inhibitors (RASi) in a multivariate-adjusted analysis of more than 27,000 patients in the Swedish Heart Failure Registry (SwedeHF). In contrast, such drugs – which included angiotensin receptor-neprilysin inhibitors (ARNi), angiotensin receptor blockers, and ACE inhibitors – were prescribed to 95% of patients younger than 70 years.

Similarly, fewer of the oldest patients were offered meds from the two other drug classes core to HF management at the time: Beta blockers and mineralocorticoid receptor antagonists (MRA).

And among those in the 80-and-older age group who were prescribed RASi or beta blockers, their uptitration more often fell short of even half the target dosage, compared with the youngest patients in the analysis.

Physicians may hold back on full guideline-directed medical therapy in their very elderly patients with HFrEF for many reasons, including a perceived likelihood of drug intolerance due to frailty or multiple comorbidities, including renal dysfunction, Davide Stolfo, MD, Karolinska Institutet, Stockholm, and University of Trieste, Italy, told this news organization.

But the current analysis was adjusted for about 80 variables “that in our interpretation may be main reasons for not introducing drugs and using them in the older patients,” he said. They included care setting (that is, inpatient or outpatient), HF severity by several measures, a range of comorbidities, renal dysfunction, and history of serious illness such as cancer.

Even then, age emerged as a significant, independent predictor of medical therapy underuse in the oldest patients. Some physicians apparently see advanced age, by itself, as an “intrinsic reason” not to abide by HFrEF medical therapy recommendations, said Dr. Stolfo, who presented the analysis at HFA 2021, the annual meeting of the Heart Failure Association of the European Society of Cardiology (ESC-HFA), conducted both virtually and live in Florence, Italy.

Most major HF-drug trials have excluded or admitted few patients aged 80 years or older, but “the guidelines recommend treatment regardless of age, and in the trials there has been no influence from age on the effectiveness of drugs,” Dr. Stolfo observed.

Moreover, in a prior SwedeHF analysis with propensity matching, patients with HFrEF aged 80 or older showed steeper reductions in risk for death or HF hospitalization from treatment with RASi than those in younger age groups.

One of the few randomized trials to focus on the very elderly, called SENIORS, enrolled patients aged 70 years and older – the average age was 76 – and saw a significantly reduced risk of death or cardiovascular hospitalization for those assigned to the beta blocker nebivolol. The benefits in the trial, which was conducted 15 years ago, were independent of left ventricular function.

So in the oldest patients, “we could question the need to achieve full dose of an evidence-based drug, but we shouldn’t question the use of these drugs.”

The findings are consistent with a need to individualize medical therapy in senior patients with HFrEF, especially those of more advanced age, some of whom may be robust enough to be managed similarly to younger patients while others who may be less suitable for full guideline-directed medical therapy, Dr. Stolfo said.

Even for those who are more frail or have major comorbidities, drug therapy of HFrEF continues to be important for symptom control even if competing causes of death make it harder to prolong survival, Dr. Stolfo said.

“We should provide to all patients the best strategy they can tolerate,” he said. “If we cannot greatly impact on the long-term survival for these patients, treatment can be aimed to improve the quality of life and keep the patient out of the hospital.”

The analysis was supported by Boehringer Ingelheim. Dr. Stolfo disclosed personal fees from Novartis, Merck, GlaxoSmithKline, and Acceleron.

Children conceived with assisted reproductive techniques (ART) do not appear to be more likely to have attention-deficit/hyperactivity disorder or poor school performance, compared with children conceived spontaneously, according to a study published in Pediatrics.

The findings, based on an analysis of data from more than 1.5 million children in Sweden, provide “additional reassurance concerning offspring neurodevelopment after use of ART,” study author Chen Wang, MPH, and colleagues said. The results show the importance of accounting for underlying infertility when studying ART safety, they added. Mr. Wang is a researcher in the department of medical epidemiology and biostatistics at Karolinska Institutet in Stockholm.

Prior research has not shown major differences during early childhood between children conceived with ART and those conceived spontaneously. To examine long-term neurodevelopmental outcomes, including ADHD and school performance, the investigators analyzed data in Swedish population registers from children born between 1986 and 2012.

Infertility and the use of ART became increasingly common during the study period, the researchers noted. Between 1986 and 2001, 7% of births were to couples with known infertility, and 13% of these births were achieved with ART. Between 1996 and 2012, 11% of births were to couples with infertility, and 26% of these births were achieved with ART.

“Couples with infertility were more likely older and married or cohabiting, compared with couples with no known infertility,” Mr. Wang and colleagues reported. “Among infertile couples, those that conceived with ART had, on average, higher age and education, and the women were less likely to smoke.”

The investigators estimated that the cumulative incidence of ADHD by age 15 years was 6.2% in children conceived with ART, 7.3% among children of couples with infertility who did not use ART, and 7.1% in children born to couples with no known infertility.

Overall, children conceived with ART were at lower risk of ADHD (hazard ratio, 0.83). But after adjusting for parental characteristics and health factors, the researchers found a “slightly elevated risk of ADHD with ART,” with adjusted HRs of 1.05-1.07.

When the researchers focused on children born to couples with infertility, ART was associated with a lower risk of ADHD (adjusted HR, 0.80), compared with spontaneous conception. Accounting for parental characteristics and health history, however, “attenuated the association toward the null,” the researchers reported.

The researchers also compared ART methods, including intracytoplasmic sperm injection versus standard in vitro fertilization (IVF), and fresh embryo transfer versus frozen embryo transfer. The various procedures were not associated with substantially different risks.

Patterns for school performance were generally similar to those for ADHD.

“In this large follow-up of nationwide birth cohorts, we observed lower risk of ADHD and slightly better overall school performance in children conceived with ART, compared with all other children. Differences in parental characteristics appeared to completely explain and even slightly reverse the associations,” the study authors said. “When the comparison was restricted to children of couples with known infertility, no differences were seen.”

The study was well designed and “spans more than 25 years of ART during which treatments have changed dramatically,” commented Barbara Luke, ScD, MPH, professor of obstetrics, gynecology, and reproductive biology at Michigan State University, East Lansing.

Dr. Luke and colleagues have studied academic achievement in children conceived with IVF in Texas. The results of the Swedish study “are in line with U.S. studies, and are generally reassuring,” Dr. Luke said.

The U.S. studies also showed that parental factors may play a role in understanding academic performance.

“In our studies of third-grade and sixth-grade academic outcomes, we found differences by racial/Hispanic origin groups, gender, and maternal age,” she said.

The study by Mr. Wang and coauthors was funded by grants from a Swedish government agency and the National Institutes of Health. The researchers and Dr. Luke had no relevant financial disclosures.

“Couples with infertility were more likely older and married or cohabiting, compared with couples with no known infertility,” Mr. Wang and colleagues reported. “Among infertile couples, those that conceived with ART had, on average, higher age and education, and the women were less likely to smoke.”

The investigators estimated that the cumulative incidence of ADHD by age 15 years was 6.2% in children conceived with ART, 7.3% among children of couples with infertility who did not use ART, and 7.1% in children born to couples with no known infertility.

Overall, children conceived with ART were at lower risk of ADHD (hazard ratio, 0.83). But after adjusting for parental characteristics and health factors, the researchers found a “slightly elevated risk of ADHD with ART,” with adjusted HRs of 1.05-1.07.

When the researchers focused on children born to couples with infertility, ART was associated with a lower risk of ADHD (adjusted HR, 0.80), compared with spontaneous conception. Accounting for parental characteristics and health history, however, “attenuated the association toward the null,” the researchers reported.

The researchers also compared ART methods, including intracytoplasmic sperm injection versus standard in vitro fertilization (IVF), and fresh embryo transfer versus frozen embryo transfer. The various procedures were not associated with substantially different risks.

Patterns for school performance were generally similar to those for ADHD.

“In this large follow-up of nationwide birth cohorts, we observed lower risk of ADHD and slightly better overall school performance in children conceived with ART, compared with all other children. Differences in parental characteristics appeared to completely explain and even slightly reverse the associations,” the study authors said. “When the comparison was restricted to children of couples with known infertility, no differences were seen.”

The study was well designed and “spans more than 25 years of ART during which treatments have changed dramatically,” commented Barbara Luke, ScD, MPH, professor of obstetrics, gynecology, and reproductive biology at Michigan State University, East Lansing.

Dr. Luke and colleagues have studied academic achievement in children conceived with IVF in Texas. The results of the Swedish study “are in line with U.S. studies, and are generally reassuring,” Dr. Luke said.

The U.S. studies also showed that parental factors may play a role in understanding academic performance.

“In our studies of third-grade and sixth-grade academic outcomes, we found differences by racial/Hispanic origin groups, gender, and maternal age,” she said.

The study by Mr. Wang and coauthors was funded by grants from a Swedish government agency and the National Institutes of Health. The researchers and Dr. Luke had no relevant financial disclosures.
