Interstitial lung diseases comprise a family of progressive pulmonary disorders that are often idiopathic or associated with various systemic diseases and that is characterized by bilateral lung involvement with inflammation and tissue remodeling or fibrosis. The impact of sex, including the anatomic and physiologic traits that one is born with, on the development and progression of interstitial lung diseases is not entirely clear. ⋯ In this review, we summarize sex-related differences in the epidemiology and progression of certain interstitial lung diseases with a focus on the connective tissue related interstitial lung diseases, idiopathic pulmonary fibrosis, and sarcoidosis. We also discuss cellular and pre-clinical studies that might shed light on the potential mechanisms responsible for these differences in the hope of unveiling potential targets for intervention and stimulating research in this needed field of investigation.

The study assessed the effects of whole- or half-night shifts on leptin, melatonin, sex hormones, interleukin (IL)-1β, tumor necrosis factor-α (TNF-α), IL-6, hematological parameters, sleep quality and attentional performance in women working in the health sector. ⋯ Half-night shifts disturbed sleep parameters and the melatonin rhythm, perturbed blood cell turnover and increased leptin levels. Whole-night shifts caused additional problems including suppressed estradiol, activated inflammatory responses and decreased visual attention. All together, the data suggest that night shifts, especially whole-night shifts, should be refrained from or countermeasures should be taken.

Women are underrepresented in medicine despite increases in the percentage of female physicians. It is unknown if academic productivity contributes to these differences. We sought to determine whether gender disparity exists in peer-reviewed literature authorship in the United States from 2000 to 2017. ⋯ Women publish research at a rate proportional to the number of academic female physicians. Disparities in leadership roles are unlikely explained by differences in publications. While gender disparities in medicine have improved, substantial disparities in leadership persist.

Faculty training awards are an important means of advancing early career faculty in research. The National Institutes of Health (NIH) Building Interdisciplinary Research Careers in Women's Health (BIRCWH) is a long-running K12 career development program and has been integral in promoting the research success of faculty nationally. We surveyed BIRCWH program directors to understand factors likely to influence long-term research careers and funding success. ⋯ K12 BIRCWH directors identified persistence and resilience and developing community, networks, and other support opportunities as elements of scholar success. Programs and mentors can help early career faculty by teaching skills and providing tools they can use to maximize the value of these opportunities and expand their mentees' research relationships. Our study also highlights the importance of social factors, particularly isolation, on clinicians, women, and minoritized scholars on career success.

Gastroparesis is a disorder where the stomach empties contents too slowly into the small intestine with associated symptoms of nausea, vomiting, postprandial fullness, bloating, early satiety and/or abdominal pain. It is a well-established fact that the female gender is more susceptible to developing gastroparesis compared to males, although the significance and rationale behind this gender inequality remains an unresolved mystery. Several hypotheses have been proposed including an intrinsically slower stomach in females, elevated levels of sex steroid hormones, loss of neuronal nitric oxide (nNOS) expression, and possibly due to altered serotonergic signaling. ⋯ Targeting these gender-specific mechanisms may lead towards future therapeutic options that might alleviate and/or prevent gastroparesis. Furthermore, a better-understanding of the sex-related differences in gastroparesis can allow medical practitioners to better tailor treatment options for their patients. This article will attempt to explain why females are more vulnerable to developing gastroparesis by examining the pathogenesis and molecular basis of gender-related factors that have been identified to play a role in the gender disparity of this entity.
