This article synthesizes the current data regarding the implication of voriconazole in the development of skin cancer in organ transplant recipients (OTRs) and offers suggestions for additional research. According to Organ Procurement and Transplantation Network data, 28 051 solid organ transplants were performed in 2012. Due to advancements in immunosuppression and management of infectious diseases, survival of OTRs has substantially increased. Voriconazole is a widely prescribed antifungal medication used for prophylaxis and for treatment of invasive fungal infections in OTRs. Case reports describing skin cancer associated with voriconazole exposure emerged shortly after US Food and Drug Administration approval of the drug, and it is now established that voriconazole is an independent risk factor for the development of cutaneous malignancy in lung transplant recipients. The mechanism of voriconazole-induced skin cancer is still unknown and may involve its primary metabolite, voriconazole N-oxide. Here we discuss the current data and potential mechanisms of voriconazole-associated photosensitivity and carcinogenesis and identify areas that require further research.

Despite a growing awareness that prostate cancer is a "couple's disease," the coping strategies, subjective distress, and emotional needs of partners are not adequately addressed. To better understand wives' experiences and processes they enact, we recruited 28 low-income Latinas caring for husbands recovering from prostatectomies to participate in interviews at three time points. Their narratives destabilize a common focus on physical side effects and an implicit bias toward men's reactions. We critically examine an overarching process of normalization, with underlying themes working both toward and against normality. We identified dissonance between detailed accounts of major lifestyle changes and professed normalization. We detail the women's purposeful methods to counteract negative impacts on their lives while seeking support externally. A better understanding of women's strategies and coping is critical to design interventions and education to both capitalize on partners' role in recovery while also addressing hidden causes of increased subjective distress.

Background: Genetic and environmental factors influence stratum corneum (SC) barrier properties and function. Researchers increasingly focus on biophysical studies that may help clinicians provide their patients with an informed choice on tailormade skincare. This literature review on skin barrier properties comparing different ethnic populations aims to offer insights into the information's clinical relevance. Methods: A literature review followed by panel discussions and an online review process aimed to answer the questions: Are there racial/ethnic differences in the SC barrier structure and healthy skin barrier function? Is there a need for specific cleansers and moisturizers? Results: Ethnic categories based on race and ethnicity are often not well defined and inconsistent across different studies. Studies comparing ethnic groups' physical and biochemical skin barrier properties have reported differences in transepidermal water loss (TEWL), skin lipid levels, pH, and mast cell granule size. However, these studies frequently had methodological flaws, mainly were small, and demonstrated conflicting results. The literature suggests racial/ethnic variations in ceramide content, SC structure, and filaggrin mutations. Furthermore, studies have shown a greater burden of pruritus and atopic dermatitis among Black populations. Data on barrier properties in Hispanic/LatinX and South Asian populations are lacking. Conclusion:Robust comparative studies are needed to understand these basic concepts to help tailor skincare and skin of color patients' education.

Advanced HIV infection is frequently complicated by diarrhea, disruption of bowel structure and function, and malnutrition. Resulting malabsorption of or pharmacokinetic changes in antiretroviral agents might lead to subtherapeutic drug dosing and treatment failure in individual patients, and could require dose adjustment and/or dietary supplements during periods of diarrheal illness. We determined the plasma levels of antiretroviral medications in patients that had already been started on medication by their physicians, in an urban infectious diseases hospital in northeast Brazil. We also obtained blood samples from patients hospitalized for diarrhea or AIDS-associated wasting, and we found reduced stavudine and didanosine levels in comparison with outpatients without diarrhea or wasting who had been treated at the same hospital clinic. There was a predominance of the protozoal pathogens Cryptosporidium and Isospora belli, typical opportunistic pathogens of AIDS-infected humans, in the stool samples of inpatients with diarrhea. We conclude that severe diarrhea and wasting in this population is associated with both protozoal pathogens and subtherapeutic levels of antiretroviral medications.

Voriconazole is a triazole antifungal used to prevent and treat invasive fungal infections after lung transplantation, but has been associated with an increased risk for developing cutaneous squamous cell carcinoma (SCC). Despite widespread use, there are no clear guidelines for optimal prophylactic regimens that balance its competing risks and benefits. We conducted a retrospective cohort study of all lung transplant recipients at the University of California, San Francisco transplanted between October 1991 and December 2012 (n=455) to investigate whether voriconazole exposure impacted development of SCC, Aspergillus colonization, invasive aspergillosis, and all-cause mortality. Voriconazole exposure was associated with a 73% increased risk for developing SCC (HR=1.73; 95% CI: 1.04–2.88; p=0.03), with each additional 30-day exposure at the standard dose increasing the risk by 3.0% (HR=1.03; 95% CI: 1.02–1.04; p<0.001). Voriconazole exposure reduced risk of Aspergillus colonization by 50% (HR=0.50; 95% CI: 0.34–0.72; p<0.001), but we were underpowered to detect risk reduction for invasive aspergillosis. Voriconazole exposure significantly reduced all-cause mortality among subjects who developed Aspergillus colonization (HR=0.34; 95% CI: 0.13–0.91; p=0.03), but had no significant impact on those without colonization. Physicians should consider patient-specific factors that modify the potential risks and benefits of voriconazole in the care of lung transplant recipients.

Childhood parentification has been associated with both positive and negative psychosocial outcomes. While divergent effects of parentification have been documented, few studies have attempted to identify variables that may impact the relationship between parentification and later adjustment. In the present study, internal locus of control, a variable associated with positive adjustment, was hypothesized as a potential moderating variable in the relationship between parentification and outcome. Using an undergraduate sample, internal locus of control was found to significantly moderate the relationship between childhood parentification and current ratings of depression and happiness. Theoretical rationales for the findings are discussed.
