Objectives Sexual minorities face significant psychosocial stressors (such as discrimination and violence) that impact their health. Several studies indicate that sexual minority women (SMW) and bisexual men may be at highest risk for cardiovascular disease (CVD), but limited research has examined physiological CVD risk or racial/ethnic differences. This study sought to examine racial/ethnic differences in physiological risk factors for CVD among sexual minority and heterosexual adults.Design We analyzed data from the National Health and Nutrition Examination Survey (2001-2016) using sex-stratified multiple linear regression models to estimate differences in physiological CVD risk. We compared sexual minorities (gay/lesbian, bisexual, 'not sure') to heterosexual participants first without regard to race/ethnicity. Then we compared sexual minorities by race/ethnicity to White heterosexual participants.Results The sample included 22,305 participants (ages 18-59). Lesbian women had higher body mass index (BMI) but lower total cholesterol than heterosexual women. Bisexual women had higher systolic blood pressure (SBP). Gay men had lower BMI and glycosylated hemoglobin (HbA1c) relative to heterosexual men. White and Black lesbian women and bisexual women of all races/ethnicities had higher BMI than White heterosexual women; Black bisexual women had higher SBP and HbA1c. Black sexual minority men had higher HbA1c relative to White heterosexual men. Latino 'not sure' men also had higher SBP, HbA1c, and total cholesterol than White heterosexual men.Conclusions Given evidence of higher CVD risk in sexual minority people of color relative to White heterosexuals, there is a need for health promotion initiatives to address these disparities. Additional research that incorporates longitudinal designs and examines the influence of psychosocial stressors on CVD risk in sexual minorities is recommended. Findings have implications for clinical and policy efforts to promote the cardiovascular health of sexual minorities.Oxygen binding proteins (O2BIP) have been actively investigated over the last five decades due to their rich redox chemistry and function as O2 carriers in blood cells, as well as their function as gasotransmitters and sensors that modulate cellular signaling. A series of meetings on the periodic advances in the knowledge gained in the field of globin structure and function are conducted typically on a biannual basis. In the fall of 2018, the XXth International Conference was conducted, and very important papers with breakthrough discoveries were presented and very enthusiastically discussed. This was yet another highly successful meeting in the series. Select papers from this meeting were recently reviewed, updated and published over several issues of Antioxidants and Redox Signaling (ARS), as forum papers communicating the latest advances in this important area of redox biology. This forum editorial introduces these articles, and highlights their scientific significance in advancing the field. Each of these articles grew out of lectures presented in the meeting, and appears either as an original contribution or a comprehensive review in the journal. Overall, the articles published in the forum provide in-depth details on the recent developments in the field as well as point the way to future directions. These forum papers thus serve as an important summary of progress and the ongoing direction of this field, and serve to highlight recent advances in our understanding of O2BIP.INTRODUCTION Limited literature exists on oncological chest wall reconstruction in the paediatric population, with the field still largely undecided on the best surgical reconstructive techniques to employ. The use of biological grafts/meshes is gaining popularity in certain adult surgical procedures but their use in paediatric procedures is rarely reported in the literature. We present the outcomes of our institution's multidisciplinary approach to managing paediatric chest wall tumours as well as our experience with the use of biological grafts for chest wall reconstruction following oncological resections. METHODS Data were analysed retrospectively from eight paediatric patients who were treated for primary chest wall tumours between 2010 and 2018. RESULTS The tumours comprised two lipoblastomas, three Ewing's sarcomas, an undifferentiated sarcoma with osteosarcomatous differentiation, a high grade undifferentiated sarcoma and a myofibroma. Seven of the eight patients underwent chest wall reconstruction with a biological graft. There were no postoperative mortalities and no evidence of recurrence in any of the patients in the series. No further chest wall operations were required and there were no postoperative infection related complications. CONCLUSIONS We support the use of biological grafts for chest wall reconstruction after oncological resections and maintain that a multidisciplinary approach is essential for the management of paediatric chest wall tumours.Anastomotic dehiscence following colonoscopy for routine surveillance after anterior resection for colorectal cancer is unreported in the English literature. It is a potentially fatal complication requiring awareness, quick recognition and management. We present the case of a 45-year-old woman who presented 12 hours after a routine follow-up colonoscopy with peritonitis due to anastomotic rupture diagnosed on computed tomography. https://www.selleckchem.com/products/actinomycin-d.html The patient was taken to theatre for emergency laparotomy and formation of an end colostomy. Her postoperative recovery and follow-up were optimal.Over 2,000 mutations have been reported in the cftr gene, many of which cause disease but are rare and have no effective treatment. Thus, there is an unmet need for new, mutation-agnostic, therapies for cystic fibrosis (CF). Phosphodiesterase (PDE) inhibitors are one such class of therapeutics that have been shown to elevate intracellular cAMP levels and stimulate CFTR-dependent anion secretion in human airway epithelia, however the number of people with CF that could be helped by PDE inhibitors remains to be determined. Here we used Fisher Rat Thyroid (FRT) cells stably transduced with rare human CFTR mutants and studied their responsiveness to the dual phosphodiesterase 3/4 inhibitor RPL554 (Verona Pharma). Through its inhibitory effect on PDE4D, we find that RPL554 can elevate intracellular cAMP leading to a potentiation of forskolin-stimulated current mediated by R334W, T338I, G551D and S549R mutants of CFTR when used alone or in combination with CFTR modulators. We also were able to reproduce these effects of RPL554 on G551D CFTR when it was expressed in primary human bronchial epithelial cells, indicating that RPL554 would have stimulatory effects on rare CFTR mutants in human airways and validating FRT cells as a model for PDE inhibitor studies.
