Prophylactic nipple‐sparing mastectomy in young previvors: Examining decision‐making,reconstructive outcomes,and patient satisfaction in BRCA+ patients under 30

Bilateral prophylactic mastectomies (BPM) in young previvors with high‐risk mutations are rising; however, little data on management, therapy timing, and outcomes exist. BRCA+ patients under 30 undergoing BPM from 2006 to 2018 were reviewed. Twenty‐two patients aged 23‐29 underwent mastectomy 4.2 years after genetic diagnosis. Twelve patients completed surveys, most often citing personal decisions (50%) for undergoing mastectomy and plastic surgeons’ recommendations (83.3%) for reconstruction. About 73% of patients completely understood risks/benefits of mastectomy and 63.6% of reconstruction. Patients reported high BREAST‐Q Satisfaction and Well‐Being scores. Continued educational resource development will optimize shared decision‐making in the reconstructive process.     

The Integration of Studio Cycling into a Worksite Stress Management Programme

High stress is a prevalent problem in the worksite. To reduce stress, improve productivity, reduce absenteeism, and lower healthcare costs, many companies offer exercise classes or stress management programmes. Although physical activity is an important component of stress management, few worksites have integrated physical activity into their comprehensive stress reduction programmes. The purpose of this single‐arm pilot project was to examine the potential effectiveness of an integrated exercise (studio cycling) and cognitive–behavioural stress management programme. Eighty‐four adults, 75% female, mostly aged 40+ years, participated in an integrated 12‐week cycling studio and cognitive–behavioural stress management programme. Participants experienced a significant and clinically meaningful reduction on the Perceived Stress Scale (p < 0.01), rating of current stress level and confidence to manage stress at the programme's end and at a 1‐month follow‐up. Participants also reported having significantly improved overall health, improved nutritional habits, higher physical activity level, greater confidence in their ability to follow a healthy diet, higher spiritual well‐being, improved sleep, receiving more support for maintaining healthy living and improved quality of life at the completion of the 12‐week programme and 1‐month follow‐up. These findings provide further support for an integrated exercise and stress management programme. Copyright © 2013 John Wiley & Sons, Ltd.     

Part-time and Job-Share Careers Among Pharmacy Practice Faculty Members

Part-time and job-share policies may allow pharmacy practice faculty members to achieve work/life balance while pursuing their professional goals. Precedent for alternative work schedules within the health professions community can be found throughout the literature; however, little is known about part-time roles in academic pharmacy. The design and implementation of 3 different alternative faculty appointments are described and department chair and faculty perspectives are shared. Teaching, service, and scholarship responsibilities, as well as outcomes before and after changes in appointment, are described. Advantages and disadvantages, including advice for other colleges of pharmacy, are presented. Alternate appointments may be a key factor in retaining highly qualified faculty members who continue to bring their expertise to teaching, precepting, and scholarship within a college or school of pharmacy.     

Small genome of the fungus Escovopsis weberi,a specialized disease agent of ant agriculture

Many microorganisms with specialized lifestyles have reduced genomes. This is best understood in beneficial bacterial symbioses, where partner fidelity facilitates loss of genes necessary for living independently. Specialized microbial pathogens may also exhibit gene loss relative to generalists. Here, we demonstrate that Escovopsis weberi, a fungal parasite of the crops of fungus-growing ants, has a reduced genome in terms of both size and gene content relative to closely related but less specialized fungi. Although primary metabolism genes have been retained, the E. weberi genome is depleted in carbohydrate active enzymes, which is consistent with reliance on a host with these functions. E. weberi has also lost genes considered necessary for sexual reproduction. Contrasting these losses, the genome encodes unique secondary metabolite biosynthesis clusters, some of which include genes that exhibit up-regulated expression during host attack. Thus, the specialized nature of the interaction between Escovopsis and ant agriculture is reflected in the parasite’s genome.The highly evolved agricultural lifestyle of leaf-cutting ants has attracted particular attention because these ants cultivate a symbiotic fungus that serves as their major food source. These ants cut leaves, preprocess them into small pieces, and feed them to the cultivated fungus (1). The capacity of the cultivated fungus to break down plant material gives ant agriculturalists access to the vast nutrient stores locked within neotropical plants (Fig. 1A) (2–5). The symbiosis between fungus-growing ants and their cultivated fungi has persisted for at least 50 million years (6).Open in a separate windowFig. 1.Escovopsis weberi, a specialized mycoparasite of the fungus-growing ant symbiosis, has a small genome compared with other Pezizomycotina fungi. (A) Both fungus-growing ants and the mycoparasite E. weberi use the ants’ cultivated fungi as their primary food source. The ability of the cultivated fungi to efficiently break down plant material gives both consumers access to the biomass of neotropical plants. (B) Size and protein-coding gene content of genomes of diverse fungi in the Pezizomycotina. Bayesian phylogeny estimated using partial amino acid alignments of three genes (Rpb1, Rpb2, ef1-α). All posterior probabilities are greater than 0.95. Phylogeny is rooted with Sacchormyces cervesiae (not shown). (C) Relationship between genome size and gene content. A list of genomes included in this panel is in SI Appendix, Table S1.Like human agriculture, ant agriculture is hampered by disease. The ants’ fungal crops are attacked and consumed by fungal parasites of the genus Escovopsis (Ascomycota, Pezizomycotina: anamorphic Hypocreales) (Fig. 1A) (7), which have evolved in association with the ants and their cultivated fungi (8). Escovopsis infection can have detrimental impacts on garden health and, consequently, on the survival of ant colonies (9, 10). Such mycoparasitism, the phenomenon whereby one fungus is parasitic on another fungus, is rare. It is most well-known for species from the genus Trichoderma, some of which are used as biocontrol agents for fungal diseases and others of which attack human-cultivated fungi (11–13). In contrast to Trichoderma species, however, Escovopsis species grow poorly in their hosts’ absence (SI Appendix, Figs. S1 and S2).Escovopsis species have never been isolated outside of fungus-growing ant colonies, and different strains of Escovopsis are capable of attacking the fungi grown by different fungus-growing ant species (8, 14, 15). The long-term, specialized evolutionary history of the association between Escovopsis and their hosts provides a unique venue to explore the consequences of host specialization on pathogen genome evolution. Here, we assemble and annotate the genome of a strain of Escovopsis weberi. Consistent with expectations under an evolutionary transition toward using a narrow host range, and similar to many other specialized, host-associated microbes (16, 17), E. weberi exhibits gene loss. Contrasting other fungal pathogens, the large genomes of which are expanded with genetic elements that influence host adaptation (18), the genome size of Escovopsis is small compared with those of its closest sequenced relatives.     

Psychological responses to serological testing for HIV

To determine the emotional impact of serological testing for HIV, 218 physically asymptomatic adults were evaluated in a confidential clinical setting 2 weeks before HIV test notification, immediately before and after notification, and 2 and 10 weeks later. All received extensive pre- and post-test counseling. The 179 seronegatives reported one or more HIV risk behaviors: homosexual intercourse (n = 111), heterosexual intercourse with possibly infected partners (n = 62), intravenous drug use (n = 20). Immediately after notification, seronegatives had significant decreases in visual analogue scale (VAS) measures of anxiety, depression, fear of getting AIDS, and fear of having infected others. Reductions were sustained at both follow-up assessments and were complemented by significant reductions on standardized self-reported measures of anxiety (Spielberger State Anxiety Inventory, SAI), depression (Beck Depression Inventory, BDI), and psychiatric symptoms (Brief Symptom Inventory, BSI) as well as by clinical ratings of depression (Hamilton Depression Rating Scale, HDRS). Of 39 seropositives, 35 had homosexual risk behaviors, seven had been intravenous drug users (IVDUs; four of whom were homosexual men), and one was a female partner of an IVDU. Immediately after notification, VAS measures of their anxiety were not significantly increased, and at 10 weeks after notification, their VAS measures of distress and mean scores on BDI, SAI and BSI were significantly lower than at entry. Their HDRS ratings were not significantly increased.

Potential Role of Direct Oral Anticoagulants in the Management of Heparin-induced Thrombocytopenia

Heparin-induced thrombocytopenia (HIT) is a rare, potentially life-threatening condition secondary to unfractionated heparin or low molecular weight heparin exposure. This immune-mediated drug reaction manifests as thrombocytopenia with a paradoxical hypercoagulable state that can result in life-threatening thrombosis. It is imperative to ensure cessation of heparin-based products as soon as HIT is identified. Traditional treatment options include argatroban, bivalirudin, fondaparinux, and danaparoid with a transition to warfarin upon platelet recovery. These anticoagulants are notwithstanding limitations including parenteral administration and routine laboratory monitoring leading to prolonged hospitalizations, emphasizing the need for new therapies. Direct oral anticoagulants (DOACs) have been increasingly investigated for the management of HIT and may overcome the aforementioned challenges of current therapies. The objective of this narrative review is to summarize the current HIT guidelines, discuss limitations to contemporary treatment options, provide insight into the emerging evidence for the DOACs rivaroxaban, apixaban, and dabigatran, and conclude with a clinical summary for their use in this setting. The PubMed, Google Scholar, and MEDLINE databases were searched for peer-reviewed literature from January 1, 2012, to June 31, 2018. Twenty-seven articles met inclusion criteria for review: 1 prospective trial, 5 retrospective cohort studies, and 21 case reports totaling 104 patients treated with a DOAC for HIT. The DOACs prevented new and recurrent thrombosis in 98% (n=102) of cases, and bleeding complications occurred in 3% (n=3). While current literature remains limited, it is suggestive of a potential role of DOACs for HIT, which has led to their integration into the 2018 American Society Hematology Guidelines with a conditional recommendation.     

Survey of County-Level Heat Preparedness and Response to the 2011 Summer Heat in 30 U.S. States

Background: Adapting to extreme heat is becoming more critical as our climate changes. Previous research reveals that very few communities in the United States have programs to sufficiently prevent health problems during hot weather.Objective: Our goal was to examine county-level local heat preparedness and response in 30 U.S. states following the unusually hot summer of 2011.Methods: Using a multimodal survey approach, we invited local health and emergency response departments from 586 counties to participate in the largest survey to date of heat preparedness and response in the United States. County-level responses were pooled into national and regional-level summaries. Logistic regressions modeled associations between heat planning/response and county characteristics, including population, poverty rates, typical summer weather, and 2011 summer weather.Results: Of 586 counties, 190 (32%) responded to the survey. Only 40% of these counties had existing heat plans. The most common heat responses were communication about heat, outreach, and collaborations with other organizations. Both heat preparedness and heat response were, on average, more extensive in counties with higher populations, lower poverty rates, and lower percentages of older people. Heat response was generally more extensive in counties with heat plans.Conclusions: Most responding counties were underprepared for extreme heat in 2011 and lacked a formal response plan. Because counties with heat plans were more likely to act to prevent adverse heat impacts to residents, local health departments should consider adopting such plans, especially because increased extreme heat is anticipated with further climate change.Citation: White-Newsome JL, Ekwurzel B, Baer-Schultz M, Ebi KL, O’Neill MS, Anderson GB. 2014.
