Epidemiology of nausea and vomiting of pregnancy: prevalence, severity, determinants, and the importance of race/ethnicity
<p>Abstract</p> <p>Background</p> <p>Studies that contributed to the epidemiology of nausea and vomiting of pregnancy have reported conflicting findings, and often failed to account for all possible co-variables necessary to evaluate the multidimensional associations. The objectives of this study were to: 1) Estimate the prevalence and the severity of nausea and vomiting of pregnancy during the 1<sup>st </sup>and the 2<sup>nd </sup>trimester of pregnancy, and 2) Identify determinants of presence and severity of nausea and vomiting of pregnancy during the 1<sup>st </sup>and 2<sup>nd </sup>trimesters separately, with a special emphasis on the impact of race/ethnicity.</p> <p>Methods</p> <p>A prospective study including pregnant women attending the Centre Hospitalier Universitaire (CHU) Sainte-Justine or RenΓ©-Laennec clinics for their prenatal care was conducted from 2004 to 2006. Women were eligible if they were β₯ 18 years of age, and β€ 16 weeks of gestation. Women were asked to fill out a 1<sup>st </sup>trimester self-administered questionnaire and were interviewed over the telephone during their 2<sup>nd </sup>trimester of pregnancy. Presence of nausea and vomiting of pregnancy was based on the reporting of pregnant women (yes/no); severity of symptoms was measured by the validated modified-PUQE index.</p> <p>Results</p> <p>Of the 367 women included in the study, 81.2% were Caucasians, 10.1% Blacks, 4.6% Hispanics, and 4.1% Asians. Multivariate analyses showed that race/ethnicity was significantly associated with a decreased likelihood of reporting nausea and vomiting of pregnancy (Asians vs. Caucasians OR: 0.13; 95%CI 0.02β0.73; and Blacks vs. Caucasians OR: 0.29; 95%CI 0.09β0.99).</p> <p>Conclusion</p> <p>Our study showed that race/ethnicity was associated with the reporting of nausea and vomiting of pregnancy in the 1<sup>st </sup>trimester of pregnancy.</p
The CD3-Zeta Chimeric Antigen Receptor Overcomes TCR Hypo-Responsiveness of Human Terminal Late-Stage T Cells
Adoptive therapy of malignant diseases with tumor-specific cytotoxic T cells showed remarkable efficacy in recent trials. Repetitive T cell receptor (TCR) engagement of target antigen, however, inevitably ends up in hypo-responsive cells with terminally differentiated KLRG-1+ CD57+ CD7β phenotype limiting their therapeutic efficacy. We here revealed that hypo-responsiveness of CMV-specific late-stage CD8+ T cells is due to reduced TCR synapse formation compared to younger cells. Membrane anchoring of TCR components contributes to T cell hypo-responsiveness since dislocation of galectin-3 from the synapse by swainsonine restored both TCR synapse formation and T cell response. Transgenic expression of a CD3-zeta signaling chimeric antigen receptor (CAR) recovered hypo-responsive T cells to full effector functions indicating that the defect is restricted to TCR membrane components while synapse formation of the transgenic CAR was not blocked. CAR engineered late-stage T cells released cytokines and mediated redirected cytotoxicity as efficiently as younger effector T cells. Our data provide a rationale for TCR independent, CAR mediated activation in the adoptive cell therapy to avoid hypo-responsiveness of late-stage T cells upon repetitive antigen encounter

Decline In Medication Affordability Despite Closure Of The Medicare Part D Coverage Gap
The original Medicare Part D benefit included a gap in coverage, commonly known as the βdoughnut hole,β where beneficiaries were responsible for 100% of drug costs. The Affordable Care Act included provisions to gradually close this gap, beginning in 2011, in order to reduce the financial burden of drug spending for Part D enrollees. Using a nationally representative survey of Medicare beneficiaries, we examined the effect of this policy on out-of-pocket drug spending and medication affordability. We found that the policy was associated with a decrease in out-of-pocket spending. However, this trend was limited to relatively healthy enrollees in stand-alone Part D plans. Surprisingly, measures of medication affordability worsened after closure of the coverage gap. These results highlight persistent problems of medication affordability in the Part D program and underscore the need for policy makers to further address the financial burden posed by medication costs
Malignant Transformation of Endometriosis in the Ischioanal Fossa
We present the case of a 28-year-old nulliparous female with malignant transformation of an ectopic focus of endometriosis in the right ischioanal fossa. A 28-year-old nulliparous patient with a past medical history of polycystic ovarian syndrome (PCOS) was diagnosed with endometrioid adenocarcinoma in her right ischioanal fossa. Initially, patient presented to an emergency department and underwent a CT scan of the appendix to rule out appendicitis. A multiloculated cystic lesion adjacent to the right obturator internus muscle was found. She underwent surgical resection of the mass, which confirmed FIGO grade 2 endometrioid adenocarcinoma, followed by localized radiation therapy. Malignancy arising in endometriosis is rare, and the influence of PCOS on the rate of malignant transformation is not well established

Robotic surgery during the COVID pandemic: why now and why for the future.
Health care has changed in unprecedented ways since the first reported cases of COVID-19. With global case rates continuing to rise and government restrictions beginning to loosen, many worry that a second wave in our future. In many hospitals around the world, non-emergent surgeries were put on hold as hospitals were transformed into COVID centers. As surgeons and administrators do their best to reinstate non-emergent procedures, guidance is sought from any and all reliable sources. Robotic surgery has many known and demonstrated benefits over open surgery and often over conventional laparoscopy. In this commentary, we aim to highlight some of the advantages robotic surgery may offer during this uniquely challenging time in health care
