Jose Bordon, MD, and colleagues aimed to define incidence and outcomes of COPD patients hospitalized with pneumonia in the city of Louisville, Ky., and to extrapolate the burden of disease in the U.S. population. They conducted a secondary analysis of data from the University of Louisville Pneumonia Study, a prospective population-based cohort study of all hospitalized adults with CAP who were residents in the city of Louisville, Ky., from June 1, 2014, to May 31, 2016.

COPD prevalence in the city of Louisville was derived via data from the 2014 Behavioral Risk Factor Surveillance System (BRFSS) as well as from the 2014 National Health Interview Survey (NHIS). In addition, the researchers analyzed clinical outcomes including time to clinical stability (TCS), length of hospital stay (LOS), and mortality, according to Dr. Bordon, an infectious disease specialist at Providence Health Center, Washington, and colleagues on behalf of the University of Louisville Pneumonia Study Group.

The researchers found an 18-fold greater incidence of community-acquired pneumonia in patients with COPD, compared with non-COPD patients.

A total of 18,246 individuals aged 40 and older with COPD were estimated to live in Louisville, Ky. The researchers found that 3,419 COPD patients were hospitalized due to CAP in Louisville during the 2-year study period. COPD patients, compared with non-COPD patients, were more likely to have a history of heart failure, more ICU admissions, and use of mechanical ventilation, compared with patients without COPD. The two groups had similar pneumonia severity index scores, and 17% received oral steroids prior to admission. COPD patients had more pneumococcal pneumonia, despite receiving pneumococcal vaccine significantly more often than non-COPD patients.

The annual incidence of hospitalized CAP was 9,369 cases per 100,000 COPD patients in the city of Louisville. In the same period, the incidence of CAP in patients without COPD was 509 per 100,000, a more than 18-fold difference.

Although the incidence of CAP in COPD patients was much higher than in those without, the difference didn’t appear to have an impact on clinical outcomes. There were no clinical differences among patients with vs. without COPD in regard to time to reach clinical improvement and time of hospital discharge, and in-hospital mortality was not statistically significantly different between the groups, the authors reported. The mortality of COPD patients during hospitalization, at 30 days, at 6 months, and at 1 year was 5.6% of patients, 11.9%, 24.3%, and 33.0%, respectively vs. 6.6%, 14.2%, 24.2%, and 30.1% in non-COPD patients. However, 1-year all-cause mortality was a significant 25% greater among COPD patients, as might be expected by the progression and effects of the underlying disease.

“[Our] observations mean that nearly 1 in 10 persons with COPD will be hospitalized annually due to CAP. This translates into approximately 500,000 COPD patients hospitalized with CAP every year in the U.S., resulting in a substantial burden of approximately 5 billion U.S. dollars in hospitalization costs,” the researchers stated.

“Modifiable factors associated with CAP such as tobacco smoking and immunizations should be health interventions to prevent the burden of CAP in COPD patients,” even though “pneumococcal vaccination was used more often in the COPD population than in other CAP patients, but pneumococcal pneumonia still occurred at a numerically higher rate,” they noted.

The study was supported by the University of Louisville, Ky., with partial support from Pfizer. The authors reported having no conflicts.

Among women with breast cancer, risk of death is more than twice as high for those who are childhood cancer survivors than for those in whom this cancer is their first, found a retrospective cohort study. However, the excess deaths are mainly from comorbidities related to previous therapies.

Breast cancer is among the leading subsequent malignancies in adult survivors of pediatric cancers, note the investigators, who were led by Chaya S. Moskowitz, PhD, of the department of epidemiology and biostatistics at Memorial Sloan Kettering Cancer Center in New York. But outcomes after this diagnosis are not well characterized.

The investigators used the Childhood Cancer Survivor Study to identify 274 female 5-year survivors of cancer diagnosed before age 21 years who received a subsequent breast cancer diagnosis at a median age of 38 years. They then used Surveillance, Epidemiology, and End Results data to identify a control group of 1,095 female patients with de novo breast cancer matched on age, race, stage, and year of breast cancer diagnosis.

The 10-year overall survival was 73% among the childhood cancer survivors, investigators reported in the Journal of Clinical Oncology.

Compared with the control women whose breast cancer was their first cancer, the women with breast cancer who were childhood cancer survivors had an elevated risk of death from any cause (hazard ratio, 2.2) that persisted after analyses were adjusted for receipt of chemotherapy and radiation therapy (HR, 2.4). In addition, findings were similar in analyses restricted to women with ductal carcinoma in situ and women with stage 1-3 breast cancer.

The childhood cancer survivors had a modestly elevated risk of dying from breast cancer (HR, 1.3) but a sharply elevated risk of dying from other health-related causes, including other subsequent malignancies and cardiovascular or pulmonary disease often related to previous therapies (HR, 5.5).

In addition, the childhood cancer survivors had a higher cumulative incidence of diagnosis of second asynchronous breast cancers a year or more later, relative to the women in whom breast cancer was their first cancer (P less than .001). The 5-year cumulative incidence was 8.0% among the childhood cancer survivors and just 2.7% among the control women.

“Although BC [breast cancer]-specific mortality was modestly higher in childhood cancer survivors, deaths attributable to health conditions other than BC seem to be the driving force in the elevated all-cause mortality,” Dr. Moskowitz and colleagues wrote.

“To change the dismal outcomes of these women, our results suggest that it is imperative that at the time of a secondary BC diagnosis, they have a comprehensive evaluation that extends beyond a singular focus of the BC,” they concluded. “This should include an assessment of existing cardiopulmonary disease and a plan for future cancer screening to optimize the management of comorbidities and cardiopulmonary disease and prolong the lifespan of these survivors.”

Dr. Moskowitz reported that she has a consulting or advisory role with Bioclinica. The study was supported by the National Cancer Institute, a Memorial Sloan Kettering Cancer Center Core grant, the Meg Berté Owen Foundation, and the American Lebanese Syrian Associated Charities.

The Diagnosis: Microvenular Hemangioma  

Microvenular hemangioma is an acquired benign vascular neoplasm that was described by Hunt et al¹ in 1991, though Bantel et al² reported a similar entity termed micropapillary angioma in 1989. Microvenular hemangioma typically presents as a solitary, slowly enlarging, red to violaceous, asymptomatic papule, plaque, or nodule measuring 5 to 20 mm in diameter. It usually is located on the trunk, arms, or legs of young adults without any gender predilection. Microvenular hemangioma is rare.³ The etiology has not been elucidated, though a relationship with hormonal factors such as pregnancy or hormonal contraceptives has been described.²  

Histopathologically, microvenular hemangioma has a characteristic morphology. It is comprised of a well-circumscribed collection of thin-walled blood vessels with narrow lumens (quiz image).⁴ The blood vessels tend to infiltrate the superficial and deep dermis and are surrounded by a collagenous or desmoplastic stroma. The endothelial cells are normal in size without atypia, mitotic figures, or pleomorphism. A mild lymphoplasmacytic inflammatory infiltrate sometimes is present. Microvenular hemangioma expresses many vascular markers confirming its endothelial origin, including CD34, CD31, WT1, factor VIII-related antigen, and von Willebrand factor.³ Moreover, WT1 staining suggests the lesion is a vascular proliferative growth, as it usually is negative in vascular malformations due to errors of endothelial development.⁵ In addition, it lacks expression of podoplanin (D2-40), which also supports a vascular as opposed to a lymphatic origin.⁴  

Cutaneous angiosarcoma is a rare and highly aggressive malignant neoplasm of the vascular endothelium with a predilection for the skin and superficial soft tissue. Clinical presentation is variable, as it can arise sporadically, commonly on the scalp and face of elderly patients, in areas of chronic radiation therapy, or in association with chronic lymphedema (Stewart-Treves syndrome).⁶ Sporadic neoplasms appear clinically as purpuric macules, plaques, or nodules and are more common in elderly men than women. They are aggressive tumors that tend to recur and metastasize despite aggressive therapy and therefore carry a poor prognosis.⁷ Histopathologically, well-differentiated tumors are characterized by irregular dissecting vessels lined with crowded inconspicuous endothelial cells (Figure 1). Cutaneous angiosarcoma is poorly circumscribed with marked cytologic atypia, and the vessels can take on a sinusoidal growth pattern.⁸ 

Kaposi sarcoma (KS) is a virally induced lymphoangioproliferative disease, with human herpesvirus 8 as the implicated agent. There are 4 principal clinical variants of KS: epidemic or AIDS-associated KS, endemic or African KS, KS due to iatrogenic immunosuppression, and Mediterranean or classic KS.⁹ Cutaneous lesions vary from pink patches to dark purple plaques or nodules that commonly occur on the lower legs¹⁰; however, the clinical appearance of KS varies depending on the clinical variant and stage. Histopathologically, early lesions of KS exhibit a superficial dermal proliferation of small angulated and jagged vessels that tend to separate into collagen bundles and are surrounded by a lymphoplasmacytic perivascular infiltrate. These native vascular structures often are surrounded by more ectatic neoplastic channels with plump endothelial cells, known as the promontory sign (Figure 2).¹¹ With more advanced lesions, the proliferation of slitlike vessels becomes more cellular and extends deeper into the dermis and subcutis. Although the histopathologic features vary with the stage of the lesion, they do not notably vary between clinical subtypes. 

Targetoid hemosiderotic hemangioma, also known as hobnail hemangioma, is a small, benign, vascular tumor that usually affects the trunk, arms, and legs in young to middle-aged adults without a gender predilection. Clinically, it appears as a small, solitary, red to purple papule or macule that typically is surrounded by a pale thin area and a peripheral ecchymotic ring, creating a targetoid appearance, thus the term targetoid hemosiderotic hemangioma.¹² Histopathologically, there is a prominent dermal vascular proliferation. In the papillary dermis, there are dilated superficial vessels lined with a single layer of endothelial cells characterized by a plump, hobnail-like appearance that protrude into the lumen (Figure 3). In the deeper dermis, the vascular spaces are angulated and slitlike and appear to dissect through collagen bundles. Hemosiderin, thrombi, extravasated erythrocytes, and a lymphocytic infiltrate also are often seen.¹³  

Tufted angioma is a rare benign vascular lesion that usually presents as an acquired lesion in children and young adults, though it may be congenital. It is commonly localized to the skin and subcutaneous tissues. Clinically, the lesions appear as red to purple patches and plaques that typically are located on the neck or trunk. More than 50% of cases present during the first year of life and slowly spread to involve large areas before stabilizing in size.¹⁴ Partial spontaneous regression may occur, but complete regression is rare.¹⁵ Lesions usually are asymptomatic but may be painful during periods of platelet trapping (Kasabach-Merritt phenomenon), which may develop in congenital cases. Tufted angioma is named for its characteristic histopathologic appearance, which consists of multiple discrete lobules or tufts of tightly packed capillaries in a cannonball-like appearance throughout the dermis and subcutis (Figure 4).^14,15

Although the histopathologic features vary with the stage of the lesion, they do not notably vary between clinical subtypes. 

Targetoid hemosiderotic hemangioma, also known as hobnail hemangioma, is a small, benign, vascular tumor that usually affects the trunk, arms, and legs in young to middle-aged adults without a gender predilection. Clinically, it appears as a small, solitary, red to purple papule or macule that typically is surrounded by a pale thin area and a peripheral ecchymotic ring, creating a targetoid appearance, thus the term targetoid hemosiderotic hemangioma.¹² Histopathologically, there is a prominent dermal vascular proliferation. In the papillary dermis, there are dilated superficial vessels lined with a single layer of endothelial cells characterized by a plump, hobnail-like appearance that protrude into the lumen (Figure 3). In the deeper dermis, the vascular spaces are angulated and slitlike and appear to dissect through collagen bundles. Hemosiderin, thrombi, extravasated erythrocytes, and a lymphocytic infiltrate also are often seen.¹³  

Tufted angioma is a rare benign vascular lesion that usually presents as an acquired lesion in children and young adults, though it may be congenital. It is commonly localized to the skin and subcutaneous tissues. Clinically, the lesions appear as red to purple patches and plaques that typically are located on the neck or trunk. More than 50% of cases present during the first year of life and slowly spread to involve large areas before stabilizing in size.¹⁴ Partial spontaneous regression may occur, but complete regression is rare.¹⁵ Lesions usually are asymptomatic but may be painful during periods of platelet trapping (Kasabach-Merritt phenomenon), which may develop in congenital cases. Tufted angioma is named for its characteristic histopathologic appearance, which consists of multiple discrete lobules or tufts of tightly packed capillaries in a cannonball-like appearance throughout the dermis and subcutis (Figure 4).^14,15  

CHICAGO – Subcutaneous (SC) daratumumab is noninferior to intravenous (IV) daratumumab for patients with relapsed or refractory multiple myeloma (MM), according findings from a phase 3 trial.

In the COLUMBA trial, SC daratumumab proved noninferior to IV daratumumab with regard to overall response rate and maximum trough concentration (Ctrough).

The safety profiles of the two formulations were similar, although patients who received SC daratumumab had a lower rate of infusion-related reactions. SC daratumumab also had a lower treatment burden.

“The COLUMBA study shows that [SC daratumumab] can be used in every myeloma patient [as a] single agent or, maybe in the future, in combination with the different backbones,” said Maria-Victoria Mateos, MD, PhD, of University Hospital of Salamanca (Spain).

Dr. Mateos presented results from the COLUMBA trial at the annual meeting of the American Society of Clinical Oncology.

Dr. Mateos cited a previous phase 1b study that had suggested that SC daratumumab might produce similar results as IV daratumumab (Blood. 2017;130:838) while providing a more convenient delivery method. She pointed out that infusions of IV daratumumab can last hours, while the SC formulation can be delivered in minutes.

The aim of the phase 3 COLUMBA study was to compare the IV and SC formulations head-to-head. The trial enrolled 522 patients with relapsed/refractory multiple myeloma. They were randomized to receive daratumumab SC (n = 263) or IV (n = 259).

The median patient age was 68 years (range, 33-92 years) in the IV arm and 65 years (range, 42-84 years) in the SC arm. Patients had received a median of four prior lines of therapy (range, 1-15 in the IV arm and 2-12 in the SC arm). Most patients were refractory to their last line of therapy – 85% in the IV arm and 80% in the SC arm – and most patients had standard-risk cytogenetics – 83% and 74%, respectively.

Treatment

Patients received SC daratumumab at 1,800 mg and IV daratumumab at 16 mg/kg. Both were given weekly for cycles 1-2, every 2 weeks for cycles 3-6, and every 4 weeks thereafter until disease progression.

The median duration of the first infusion was 421 minutes in the IV arm and 5 minutes in the SC arm. The median duration of the second infusion was 255 minutes and 5 minutes, respectively, and the median duration of subsequent infusions was 205 minutes and 5 minutes, respectively.

At a median follow-up of 7.46 months, 57% of patients in each arm had discontinued the study treatment. The most common reasons for discontinuation were progression – 44% of the IV arm and 43% of the SC arm – and adverse events (AEs) – 8% and 7%, respectively.

Safety

Dr. Mateos said the safety profiles of IV and SC daratumumab were comparable. However, infusion-related reactions were significantly less likely in the SC arm, occurring in 12.7% of those patients and 34.5% of patients in the IV arm (P less than .0001).

Grade 3 or higher treatment-emergent AEs occurred in 49% of patients in the IV arm and 46% of those in the SC arm. Rates of grade 5 AEs were 7% and 5%, respectively. The most common grade 3/4 AEs (in the IV and SC arms, respectively) were anemia (14% and 13%), thrombocytopenia (14% for both), neutropenia (8% and 13%), lymphopenia (6% and 5%), and hypertension (6% and 3%).

Efficacy

One of the study’s primary endpoints was overall response rate, which was 37.1% in the IV arm and 41.1% in the SC arm (relative risk, 1.11; 95% CI, 0.89-1.37; P less than .0001). This met the criteria for noninferiority, and overall response rates were comparable across all patient subgroups, Dr. Mateos noted.

The rates of complete response or stringent complete response were also comparable at 2.7% in the IV arm and 1.9% in the SC arm. Rates of very good partial response were 17.0% and 19.0%, respectively.

The study’s other primary endpoint was maximum Ctrough predose on day 1 of cycle 3. The ratio of maximum Ctrough for daratumumab SC over IV was 107.93% (90% CI, 95.74%-121.67%), which met the noninferiority criterion.

Survival outcomes were also similar between the IV and SC arms. The median progression-free survival was 6.1 months and 5.6 months, respectively (P = .9258). The rate of overall survival at 6 months was 83.0% and 87.5%, respectively (P = .6032).

Considering these results together, Dr. Mateos and colleagues concluded that SC daratumumab is noninferior to IV daratumumab.

“[SC daratumumab] has a reduced treatment burden due to a considerably shorter administration duration, and patients treated with [SC daratumumab] reported higher satisfaction with therapy,” Dr. Mateos said.

The results support the use of flat-dose 1,800-mg SC daratumumab, which is comparable with the IV formulation, she said.

The COLUMBA trial was sponsored by Janssen Research & Development. Dr. Mateos reported relationships with Amgen, Celgene, Janssen-Cilag, and Takeda.

Mary Alissa Willis, MD, is the Medical Director for the Mellen Center for Multiple Sclerosis at the Cleveland Clinic. We spoke with Dr. Willis about mental health issues in persons with MS and what health care facilities can do to better care for these patients.

What is the prevalence of depression in patients with MS?
Depression and anxiety are common in persons with multiple sclerosis (PwMS). In a systematic review, Ruth Ann Marrie, MD, PhD, and colleagues estimated the prevalence of depression in PwMS to be 23.7%. Approximately half of all PwMS experience depression at some point after their diagnosis.^1-3 This makes depression nearly twice as common in MS as in the general population.

What are some reasons patients with MS might begin to experience depression? What are some warning signs to look out for?

Many people assume that PwMS experience depression because of psychosocial stressors, unpredictability of disease progression, or poor coping strategies. Although these factors do contribute to depression, there is increasing evidence that immune dysregulation and structural changes in the brain caused by MS disease activity make some PwMS uniquely vulnerable to depression. Functional MRI studies have shown abnormalities in the prefrontal-subcortical network connectivity, which is involved in mood regulation. In addition, persistent somatic symptoms such as severe pain and fatigue limit daily activities and social participation—generally considered to be protective factors in depression.⁴ Warning signs for depression include loss of interest in activities, weight loss or weight gain, changes in sleep—too much or too little, an increase in fatigue, expressions of hopelessness or guilt, or increasing drug or alcohol use. 

What are some special considerations for patients with MS battling suicidal ideation?

Anthony Feinstein, MBBCh, MPhil, PhD, and colleagues reported that more than 28% of PwMS had suicidal ideation at some point.⁵ This is a huge number of people struggling with thoughts of suicide. Depression is a risk factor for suicide but other risks specific to PwMS include perceived loss of control, loss of job/income/social roles, loss of driving privileges, and marked physical or cognitive difficulties. While we are doing a better job screening for depression with quick screening tools such as the PHQ9, we could do better in suicide risk assessment.

What can health care providers do better to address depression and risk for suicide? What safety/preventative measures can they take?

 The first step in better addressing depression and risk for suicide is to directly ask patients. Pay attention to changes in appearance, behavior, requests for prescription refills, frequency of appointments, and who accompanies patients to appointments. Explore the reasons for these changes. It is important to respond proactively when comments or behavior suggest a patient at risk. Ask specific questions about plan, access to means, previous suicide attempts, and support network. Refer promptly for emergency or mental health services when appropriate. Familiarity with mental health colleagues, local crisis centers, and helplines can be helpful in engaging a team of people to provide assistance to a patient in need.

Among pregnant women with inherited bleeding disorders, having a contraindication to regional anesthesia appears not to impact labor outcomes, according to a retrospective analysis.

oceandigital/Thinkstock

“The purpose of this study was to determine the anesthetic use in labour in a cohort of women with inherited bleeding disorders,” wrote Sean C. Boyd, of Coombe Women & Infants University Hospital in Dublin, Ireland, and colleagues. The findings were reported in the European Journal of Obstetrics & Gynecology and Reproductive Biology.

The study comprised 97 pregnant women with an inherited bleeding disorder and outcomes related to 130 delivered newborns.

The researchers reviewed medical records of patients with a variety of inherited bleeding disorders: type 1 von Willebrand disease (VWD), deficiencies of factors VII, VIII, IX, X, and XI, combined deficiencies, and others.

Various clinical data, including both obstetric and anesthetic outcomes, were collected from January 2011 to December 2016.

When researchers compared pregnancies where regional anesthesia was contraindicated to those in which it was considered safe, women with a contraindication were more likely to receive general anesthesia for cesarean section (20% vs. 1%), more likely to use a remifentanil infusion (31% vs. 0), and more likely to require prophylactic hemostatic support for delivery (61% vs. 1%).

Vaginal (71% vs. 65%; P = .4) and caesarean section (29% vs. 32%; P = .28) delivery rates were similar between the two groups.

Rates of postpartum hemorrhage were greater in pregnancies where regional anesthesia was contraindicated (24% vs. 12%), but not significantly different (P = .07). No cases of vertebral canal hematoma or neonatal hemorrhage were reported among participants.

“Women are anxious about analgesia and anesthesia in labour and understandably, more so, when they are aware that they are unable to have an epidural or spinal,” the researchers wrote. “This study shows what alternative analgesia is used in labour and, reassuringly, that labour outcome is the same.”

Two key limitations of the study were the small sample size and the wide range of included bleeding disorders.

No funding sources were reported. The authors did not report conflicts of interest.

Boyd, of Coombe Women & Infants University Hospital in Dublin, Ireland, and colleagues. The findings were reported in the European Journal of Obstetrics & Gynecology and Reproductive Biology.

The study comprised 97 pregnant women with an inherited bleeding disorder and outcomes related to 130 delivered newborns.

The researchers reviewed medical records of patients with a variety of inherited bleeding disorders: type 1 von Willebrand disease (VWD), deficiencies of factors VII, VIII, IX, X, and XI, combined deficiencies, and others.

Various clinical data, including both obstetric and anesthetic outcomes, were collected from January 2011 to December 2016.

When researchers compared pregnancies where regional anesthesia was contraindicated to those in which it was considered safe, women with a contraindication were more likely to receive general anesthesia for cesarean section (20% vs. 1%), more likely to use a remifentanil infusion (31% vs. 0), and more likely to require prophylactic hemostatic support for delivery (61% vs. 1%).

Vaginal (71% vs. 65%; P = .4) and caesarean section (29% vs. 32%; P = .28) delivery rates were similar between the two groups.

Rates of postpartum hemorrhage were greater in pregnancies where regional anesthesia was contraindicated (24% vs. 12%), but not significantly different (P = .07). No cases of vertebral canal hematoma or neonatal hemorrhage were reported among participants.

“Women are anxious about analgesia and anesthesia in labour and understandably, more so, when they are aware that they are unable to have an epidural or spinal,” the researchers wrote. “This study shows what alternative analgesia is used in labour and, reassuringly, that labour outcome is the same.”

Two key limitations of the study were the small sample size and the wide range of included bleeding disorders.

No funding sources were reported. The authors did not report conflicts of interest.

Primary cutaneous melanomas more than 2 mm thick can be excised with 2-cm margins with outcomes similar to excision with 4-cm margins, based on data from a randomized, multicenter trial of 936 patients.

“Over time, and in light of the findings of several randomized studies, less extensive surgery for primary melanoma with tumor thickness greater than 2 mm has become more established,” and most recent guidelines recommend a 2-cm margin for these tumors, wrote Deborah Utjés, MD, of the Karolinska Institute in Stockholm and colleagues.

To reinforce the safety and effectiveness of the 2-cm margin, the researchers conducted an open-label, randomized trial of clinically staged melanoma patients aged 75 years and younger with localized cutaneous melanomas thicker than 2 mm, from January 1992 to May 2004. Patients were treated in Denmark, Estonia, Norway, and Sweden. The findings were published in the Lancet.

Patients were randomized to treatment with a 2-cm (471) or 4-cm excision margin (465). The melanomas were located on the trunk, upper extremities, or lower extremities.

The primary outcome of overall survival was similar between the groups. Over a median 20-year follow-up period, the death rate was approximately 50% in each group (49% in the 2-cm group and 51% in the 4-cm group). Disease-specific survival rates were similar as well. Of the 621 reported deaths, 397 were attributed to melanoma: 192 (48%) in the 2-cm group and 205 (52%) in the 4-cm group.

The study findings were limited by several factors, including a lower-than-expected number of patients, lack of nodal staging during the study period, and a focus only on the surgical margin without recording data on pathological excision margins.

However, the extended follow-up supports the safe use of the 2-cm margin for the treatment of melanomas thicker than 2 mm, the investigators wrote. In addition, results from an ongoing trial comparing 1-cm and 2-cm margins for melanomas at least 1 mm thick may yield more evidence to support still narrower surgical margins for some cutaneous melanomas.

The study notes that guidelines from organizations that include the American National Comprehensive Cancer Network and the American Academy of Dermatology recommend the 2-cm margin for tumors that are thicker than 2 mm.

The study was supported by the Swedish Cancer Society, Stockholm Cancer Society, Swedish Society for Medical Research, and the Stockholm County Council, and by funds from Radiumhemmet Research and Wallström. The authors reported no disclosures.

Cockatoo cha-cha-cha

GlobalP/iStock/Getty Images Plus

Humans love to dance. Whether it’s just a little bobbing back and forth or a full-on tango, spontaneous dancing is a universal expression of feeling and joy. However, feeling the rhythm is nearly unique to the human species. Not even our closest relatives in the animal kingdom, primates, have been observed busting a move to music.

So who are our ballroom brethren? Parrots, strangely enough. Parrots are nature’s great imitators, so how can we be sure they aren’t just mimicking (or mocking) their human owners’ movements?

Several studies have been conducted on a particularly funky cockatoo named Snowball. He’s a viral Internet sensation, and researchers have been watching him for the past decade as he stomps his feet and bangs his head to all kinds of music – he jams to everything from classic rock to modern pop. Snowball’s owner also assured scientists that her bird does not get his dance moves from her; Snowball is a unique choreographer.

A follow-up study about Snowball was recently published, in which the authors suggested the reason for spontaneous parrot dancing could be the strong auditory-motor connections that exist in parrot brains. They’re similar to humans, but not primates. They also detailed Snowball’s 14 distinct dance moves. Someone get that parrot on America’s Got Talent, ASAP.
 

It’s a bird, it’s a plane – oh no, it’s a spider

Arachnophobes, just skip this one. If you’re not unsettled by spiders yet, you’re about to be!

In case you didn’t know, spiders can fly. Or rather, they float (spiders with wings would just be straight-up horrifying).

Scientists (and fans of Charlotte’s Web) have known for centuries that spiders can turn into their own personal airships, but it wasn’t always clear how they do it. It was commonly believed that spider-flying, aka “ballooning,” was caused by the spider using its silk as a kind of kite, with the wind catching on the silk and bringing the spider along with it. That explanation, however, doesn’t account for the fact that spiders only balloon during light winds, which are rarely strong enough to carry a spider.

Two intrepid spider fans from the University of Bristol (England) think they have solved the mystery of the flying arachnids.

It turns out that spiders are able to sense the earth’s electric field and use that to soar around. They let loose some silk, which picks up a negative charge. This charge repels the negative charge of whatever they are standing on and can create enough force to launch them into the air. Spiders, those smart little buggers, can increase these charges by climbing onto twigs or grass. Plants rooted in the earth have a strong negative charge but stick up into the positively charged air.

All this fancy science-babble to say: Spiders can fly, and we know how! Stay indoors, folks.
 

Hospital lures fishermen to ED

There are some things you expect to see when you walk into a hospital: an admitting desk, waiting areas full of people, security guards, bad art work, maybe a friendly greeter at the door (sorry, that’s the Walmart).

The main lobby at Adirondack Medical Center in Saranac Lake, N.Y., however, has something you might not expect: a display of fishing lures.

Each of the more than 100 lures on display originally showed up at the hospital’s emergency department attached to an arm, leg, nose, or lip – pretty much every body part possible, Gary Nye, a physician assistant in the ED, told newyorkupstate.com. He’s even removed lures from several patients’ penises and scrotums. “Usually alcohol has something to do with it,” he noted.

One individual came in with hooks from a lure stuck on both thumbs. He got one set of hooks stuck on one thumb, and as he tried to get it out, he ended up getting the lure’s other set of hooks caught on his other thumb. A nurse who has worked in the ED for 20 years said that alcohol may been involved.

Dr. Michael Pond, the hospital’s former medical director and the one who started the display in 1990, explained why the lures are now kept in a locked case. A number of years ago, when the display was less secure, “someone cut out and stole four to five antique lures out of the case. I mean, these were absolutely gorgeous and expensive lures – Pikie Minnows and [other] things. [They] were made out of wood and painted.”

As with so many fish stories, you should have seen the one that got away.

On the surface, a study detailing a new, potentially practice-changing method of converting type A blood to type O doesn’t seem disgusting, silly, or odd enough to make it into Livin’ on the MDedge. But when you dig a little deeper, you’ll see that the method involves a bacteria in the human microbiome.

Now you might be getting a bit suspicious. This is going to be another story about poop, you might be thinking.

And you’d be right!

But the real star of the show isn’t human poop. No, in this case, we owe this groundbreaking discovery to the humble beaver.

In an earlier study published in the ISME Journal, the same group of researchers from the University of British Columbia in Vancouver (of course they’re Canadian) analyzed the microbiomes of beavers to see just how they broke down the complex carbohydrates and glycoproteins found in wood. That was the catalyst that got the researchers thinking about the human microbiome and the problem of stripping red blood cells of their antigens.

Basically, just as the beaver breaks down wood with bacteria in their microbiome, the modified bacteria the researchers conjured up can be used to break down the A and B antigens of red blood cells, leaving a simple type O cell that can be transfused into any patient.

Rumors that all future blood transfusions are required by law to be accompanied by a playing of O Canada remain unsubstantiated.

CoolTone also is indicated for the strengthening, toning, and firming of buttocks and thighs. Using magnetic muscle stimulation, CoolTone technology penetrates into the muscle layers and induces involuntary muscle contractions. The body responds to these contractions by strengthening its muscle fibers, resulting in a more defined and toned appearance. For more information, visit www.cooltonebycoolsculpting.com.

Duobrii Lotion for Plaque Psoriasis Now Available

Ortho Dermatologics announces the US launch of Duobrii (halobetasol propionate and tazarotene) Lotion 0.01%/0.045%. Duobrii was approved by the US Food and Drug Administration in April 2019 for the treatment of plaque psoriasis in adult patients, offering psoriasis patients a treatment with strong efficacy and an extended duration of use in a once-daily lotion that can be dosed to clearance. When used separately to treat plaque psoriasis, the duration of use of halobetasol propionate is limited to 2 to 4 weeks, and the use of tazarotene can be limited due to tolerability concerns. By combining halobetasol propionate and tazarotene in a patented once-daily moisturizing lotion, the Duobrii formulation ensures uniform distribution, allowing for simultaneous contact with the skin surface. Unlike other topical products that either contain steroids or are steroids on their own, Duobrii is not restricted to 8 weeks or less of use. The approved labeling for Duobrii does not include a duration limitation; it can be dosed to clearance as long as local skin reactions do not occur, and treatment should be discontinued once clearance is achieved. For more information, visit www.duobrii.com.

Zika Virus Diagnostic Test Receives Marketing Authorization

The US Food and Drug Administration authorizes marketing of the ZIKV Detect 2.0 IgM Capture ELISA (enzymelinked immunosorbent assay)(InBios International, Inc) for the qualitative detection of Zika virus IgM antibodies in human blood. The ZIKV Detect 2.0 IgM Capture ELISA is designed to identify proteins (antibodies) produced by the body’s immune system when it tests for Zika virus infection in the blood; IgM antibodies indicate an early immune response. The test is for use only in patients with clinical signs and symptoms consistent with Zika virus infection and/or those who meet the Centers for Disease Control and Prevention’s Zika virus epidemiologic criteria, such as history of residence in or travel to a geographic region with active Zika transmission at the time of travel.

AbbVie Inc and Allergan announce that the companies have entered into a definitive transaction agreement under which AbbVie will acquire Allergan in a cash and stock transaction. The combined company will consist of several franchises with leadership positions across immunology, hematologic oncology, medical aesthetics, neuroscience, women’s health, eye care, and virology. Furthermore, Allergan’s product portfolio will be enhanced by AbbVie’s commercial strength, expertise, and international infrastructure. For more information, visit www.abbvie.com and www.allergan.com.

Avène Launches Mineral Sunscreen Fluids

Pierre Fabre Dermo-Cosmetique introduces Avène Mineral Sunscreen Fluids SPF 50+ in both tinted and nontinted varieties. With active ingredients titanium dioxide (11.4%) and zinc oxide (14.6%), both products provide broad-spectrum UVA and UVB protection and are free from octinoxate and oxybenzone (reef friendly). These lightweight lotions are ideal for use on the face; they absorb quickly and can be layered invisibly under makeup. Additionally, the tinted fluid offers protection against blue light. For more information, visit www.aveneusa.com.

CoolTone Device Clearance Expanded

Allergan announces US Food and Drug Administration clearance of the nonsurgical CoolTone device for the improvement of abdominal tone, strengthening of the abdominal muscles, and development for firmer abdomen. CoolTone also is indicated for the strengthening, toning, and firming of buttocks and thighs. Using magnetic muscle stimulation, CoolTone technology penetrates into the muscle layers and induces involuntary muscle contractions. The body responds to these contractions by strengthening its muscle fibers, resulting in a more defined and toned appearance. For more information, visit www.cooltonebycoolsculpting.com.

Duobrii Lotion for Plaque Psoriasis Now Available

Ortho Dermatologics announces the US launch of Duobrii (halobetasol propionate and tazarotene) Lotion 0.01%/0.045%. Duobrii was approved by the US Food and Drug Administration in April 2019 for the treatment of plaque psoriasis in adult patients, offering psoriasis patients a treatment with strong efficacy and an extended duration of use in a once-daily lotion that can be dosed to clearance. When used separately to treat plaque psoriasis, the duration of use of halobetasol propionate is limited to 2 to 4 weeks, and the use of tazarotene can be limited due to tolerability concerns. By combining halobetasol propionate and tazarotene in a patented once-daily moisturizing lotion, the Duobrii formulation ensures uniform distribution, allowing for simultaneous contact with the skin surface. Unlike other topical products that either contain steroids or are steroids on their own, Duobrii is not restricted to 8 weeks or less of use. The approved labeling for Duobrii does not include a duration limitation; it can be dosed to clearance as long as local skin reactions do not occur, and treatment should be discontinued once clearance is achieved. For more information, visit www.duobrii.com.

Zika Virus Diagnostic Test Receives Marketing Authorization

The US Food and Drug Administration authorizes marketing of the ZIKV Detect 2.0 IgM Capture ELISA (enzymelinked immunosorbent assay)(InBios International, Inc) for the qualitative detection of Zika virus IgM antibodies in human blood. The ZIKV Detect 2.0 IgM Capture ELISA is designed to identify proteins (antibodies) produced by the body’s immune system when it tests for Zika virus infection in the blood; IgM antibodies indicate an early immune response. The test is for use only in patients with clinical signs and symptoms consistent with Zika virus infection and/or those who meet the Centers for Disease Control and Prevention’s Zika virus epidemiologic criteria, such as history of residence in or travel to a geographic region with active Zika transmission at the time of travel.

For clinicians seeking to provide a pathway to treatment or diagnosis that is individualized to the patient, a recent study found that the issues go beyond awareness or a patient’s degree of comfort – there remains the question of something as simple as: what should we call it?

Clinicians remain uncertain whether to name the new field precision or personalized medicine according the new CHEST Clinical Perspectives^TM white paper, “Precision Medicine: Adoption of Emerging Methods of Evaluation and Therapy.” A survey of leading community clinicians from among CHEST membership found that only 35 % called tailoring medical treatment to the individual characteristics of each patient “precision medicine,” with 24% preferring “personalized” medicine. Thirty-six percent of respondents used the terms interchangeably.

Beyond the communication issues, the study found that most clinicians surveyed did not know enough about precision medicine to adopt it into their practice. Those surveyed reported that they wanted to see more published studies on the effectiveness of the newly available tools before discussing these options with their patients.

The majority of the respondents were general pulmonologists with intensivists and interventional pulmonologists also responding. The study was led by Nichole T. Tanner, MD, MSCR, FCCP, of the Medical University of South Carolina. Dr Tanner will be hosting a webinar to review the conclusions of this paper at 10:00 AM CT on Tuesday, July 30.
