Background Very little is known regarding the readiness of senior U.S. Ob/Gyn residents to perform minimally invasive surgery. This study aims to evaluate the self-perceived readiness of senior Ob/Gyn residents to perform complex minimally invasive gynecologic surgery as well as their perceptions of the minimally invasive gynecologic surgery subspecialty. Methods We performed a national survey study of 3rd and 4th year Ob/Gyn residents. A novel 58-item survey was developed and sent to residency program directors and coordinators with the request to forward the survey link along to their senior residents. Results We received 158 survey responses with 84 (53.2%) responses coming from 4th year residents and 74 (46.8%) responses from 3rd year residents. Residents who train with graduates of a fellowship in minimally invasive gynecologic surgery felt significantly more prepared to perform minimally invasive surgery compared to residents without this exposure in their training. The majority of senior residents (71.5%) feel their residency training adequately prepared them to be a competent minimally invasive gynecologic surgeon. However, only 50% feel prepared to perform a laparoscopic hysterectomy on a uterus greater than 12 weeks size, 29% feel prepared to offer a vaginal hysterectomy on a uterus 12-week size or greater, 17% feel comfortable performing a laparoscopic myomectomy, and 12% feel prepared to offer a laparoscopic hysterectomy for a uterus above the umbilicus. Conclusions The majority of senior U.S. Ob/Gyn residents feel prepared to provide minimally invasive surgery for complex gynecologic cases. However, surgical confidence in specific procedures decreases when surgical complexity increases.Background CD8+ T cell trafficking to the tumor site is essential for effective colorectal cancer (CRC) immunotherapy. However, the mechanism underlying CD8+ T cell infiltration in colorectal tumor tissues is not fully understood. In the present study, we investigated CD8+ T cell infiltration in CRC tissues and the role of chemokine-chemokine receptor signaling in regulation of T cell recruitment. Methods We screened chemokines and cytokines in healthy donor and CRC tissues from early- and advanced-stage patients using multiplex assays and PCR screening. We also utilized transcription factor activation profiling arrays and established a xenograft mouse model. Results Compared with tumor tissues of early-stage CRC patients, CD8+ T cell density was lower in advanced-stage tumor tissues. PCR screening showed that CXCL10 levels were significantly increased in advanced-stage tumor tissues. CXCR3 (the receptor of CXCL10) expression on CD8+ T cells was lower in the peripheral blood of advanced-stage patients. The migratory ability of CD8+ T cells to CXCL10 depended on CXCR3 expression. Multiplex arrays showed that IL-17A was increased in advanced-stage patient sera, which markedly downregulated CXCR3 expression via activating STAT3 signaling and reduced CD8+ T cell migration. Similar results were found after CD8+ T cells were treated with Th17 cell supernatant. Adding anti-IL-17A or the STAT3 inhibitor, Stattic, rescued these effects in vitro and in vivo. Moreover, survival analysis showed that patients with low CD8 and CXCR3 expression and high IL-17A levels had significantly worse prognosis. Conclusions CD8+ T cell infiltration in advanced-stage tumor was systematically inhibited by Th17 cells via IL-17A/STAT3/CXCR3 axis. Our findings indicate that the T cell infiltration in the tumor microenvironment may be improved by inhibiting STAT3 signaling.Background Significant long-term reduction in health-related quality of life (HRQoL) is often observed in survivors of the acute respiratory distress syndrome (ARDS), and return to work (RtW) is limited. There is a paucity of data regarding the relationship between the quality of care (QoC) in the intensive care unit (ICU) and both HRQoL and RtW in ARDS survivors. Therefore, the aim of our study was to investigate associations between indicators of QoC and HRQoL and RtW in a cohort of survivors of ARDS. Methods To determine the influence of QoC on HRQoL and RtW 1 year after ICU-discharge, ARDS patients were recruited into a prospective multi-centre patient cohort study and followed up regularly after discharge. Patients were asked to complete self-report questionnaires on HRQoL (Short Form 12 physical component scale (PCS) and mental component scale (MCS)) and RtW. Indicators of QoC pertaining to volume, structural and process quality, and general characteristics were recorded on ICU level. Associations betwe during ICU stay and variables pertaining to the post intensive care period (e.g. rehabilitation) cannot be ruled out. Trial registration Clinicaltrials.govNCT02637011.

Our objective was to examine current clinical practices and their impact in this expanded population of CLL patients who often require adjustments in the standard prescribed dose and schedule of therapy. Materials and methods An extensive review of the medical literature was conducted to establish the consensus on ibrutinib dose modifications in patients with CLL. Twenty-nine studies were reviewed including fourteen clinical trials and fifteen "real-world practice" studies. Results The average discontinuation rate was similar between clinical trials and "real-world practice" studies though the reasons for discontinuation differed. CLL progression was a more common reason for discontinuation in clinical trial studies while toxicity was a more common reason for discontinuation in "real-world practice" studies. Some studies have suggested worse outcomes in patients requiring dose reductions in ibrutinib while others have shown no change in treatment efficacy in patients requiring dose reductions due to concomitant CYP medications or increased immunosuppression post-transplant. Conclusion The impact of ibrutinib dose modifications on clinical outcome remains unclear. Patients on concomitant CYP3A inhibitors should be prescribed a lower dose than the standard 420 mg daily, in order to maintain comparable pharmacologic properties. Further research is required to establish definitive clinical practice guidelines.
