n of dynamic CA induced by hypercapnia. Further studies are needed to assess the relevance of CrCP contribution in physiological and clinical studies.Approximate analytic expressions are derived for the electrophoretic mobility of spheroidal particles (prolate and oblate) carrying low zeta potential in an electrolyte solution under an applied tangential or transverse electric field. The present approximation method, which is based on the observation that the electrophoretic mobility of a particle is determined mainly by the distortion of the applied electric field by the presence of the particle. The exact expression for the equilibrium electric potential distribution around the particle, which can be expressed as an infinite sum of spheroidal wave functions, is not needed in the present approximation. The electrophoretic mobility values calculated with these approximate expressions for spheroidal particles with constant surface potential or constant surface charge density are in excellent agreement with the exact numerical results of previous reports with the relative errors less than about 4%.
Inflammatory bowel disease (IBD) patients living in regional or remote Queensland are often disadvantaged by limited access to IBD specialist care. Telehealth clinics could potentially address this disparity and improve patient outcomes.
We report the impact of the Royal Brisbane and Women's Hospital (RBWH) IBD telehealth clinics from March 2011 to December 2017 including patient satisfaction and healthcare activity.
Patient satisfaction surveys were collected prospectively between March 2011 and March 2012. Healthcare activity was assessed through occasions of service (OOS), number of enrolled patients on biologics and IBD related admissions to RBWH.
Overall, 3764 OOS were completed including 576 new patient and 3188 follow up visits. Mean age at first telehealth visit was 44 years (range16-87). The IBD telehealth clinics were well accepted with 99% of the first 153 patients surveyed choosing to continue with telehealth and 94% rated the telehealth experience as very good or excellent. The net number of patients under active review increased from 125 patients in 2011 to 345 patients in 2017. Enrolled patients on biologics also increased from 9 patients in 2011 to 63 patients in 2017. There was an initial dip in annual IBD related admissions to RBWH in 2011 but these have progressively increased over time although the average length of inpatient stay annually has remained stable.

Few human protection policies directly address the protection of research bystanders, though some address it in passing. In what follows, I re-iterate reasons why bystanders are entitled to protections. I also argue that Institutional Review Boards (IRBs) are in the best position to signal to researchers and sponsors that bystanders should be protected in research. In some cases, IRB review would consist of evaluating bystander protection strategies directly; in other cases, this might entail merely certifying that another institutions, like a drug regulator, has taken adequate measures to protect the welfare of research bystanders.
We previously reported on a phase 2 study of everolimus plus bevacizumab across various nonclear cell renal cell carcinoma (nccRCC) histologies and observed encouraging activity among patients with papillary RCC (pRCC) and unclassified RCC (uRCC) with a major papillary component. We subsequently expanded the study to enroll additional patients with pRCC variants.
Everolimus plus bevacizumab was administered at standard doses until disease progression or intolerance to therapy. The primary endpoint was the 6-month progression-free survival (PFS) rate; secondary endpoints included objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and safety. Correlative analyses included next-generation sequencing (NGS) from tumor and germline across >341 genes of interest.
In addition to 19 patients with pRCC variants in the original cohort, 20 patients with similar features were enrolled on the expansion cohort (uRCC with papillary features [n=24], pRCC [n=14], and translocation-associated RCC with papillary features [n=1]). Among 37 evaluable patients, the 6-month PFS rate was 78%, the median PFS was 13.7 months (95% CI, 10.8-16.4 months), and the ORR was 35%. With a median follow-up of 17.6 months, the median OS was 33.9 months (95% CI, 23.3-71.9). Tolerance was consistent with prior reports for everolimus plus bevacizumab. NGS results (n=33) identified responses in patients with a wide spectrum of genomic alterations, including ARID1A, FH, and MET mutations.
The expansion cohort results confirm robust activity of everolimus plus bevacizumab in metastatic pRCC variants, supporting this regimen as a standard option for this patient population.

In this meta-analysis, we assessed the association of obesity and outcomes in COVID-19 hospitalized patients. Data from observational studies describing the obesity or body mass index and outcomes of COVID-19 hospitalized patients from December 1, 2019, to August 15, 2020, was extracted following PRISMA guidelines with a consensus of two independent reviewers. Adverse outcomes defined as intensive care units, oxygen saturation less than 90%, invasive mechanical ventilation, severe disease, and in-hospital mortality. The odds ratio (OR) and 95% confidence interval (95% CI) were obtained and forest plots were created using random-effects models. A total of 10 studies with 10,233 confirmed COVID-19 patients were included. The overall prevalence of obesity in our study was 33.9% (3473/10,233). In meta-analysis, COVID-19 patient with obesity had higher odds of poor outcomes compared with better outcomes with a pooled OR of 1.
