The copper-based oxide catalysts have garnered significant attention due to their remarkable capacity for selectively producing multicarbon (C2+) compounds in CO2 reduction by renewable-electricity-driven. However, the Cu+ species in catalysts...
Abstract Recurrent pregnancy loss (RPL) is a serious pregnancy disease caused by a variety of factors. Obstetric antiphospholipid syndrome (OAPS) is the most prevalent treatable cause of RPL. Although some RPL patients do not meet the diagnosis of OAPS, they may benefit from the standard treatment of OAPS. However, the diagnosis and treatment of these patients are controversial. To evaluate the value of “non-criteria” antiphospholipid antibodies (aPLs) in RPL patients, and to assess whether RPL patients with “criteria”/ “non-criteria” aPL positivity could benefit from treatment with low-molecular-weight heparin (LMWH) and low-dose aspirin (LDA), we profiled five “criteria” and ten “non-criteria” aPLs, namely LA, aCL IgG/M, aβ2GPI IgG/M, aPS/PT IgG/M, aANXA5, aANXA2, aVIM, aβ2GPI-D1, aPE, aPI IgG/M, aPS IgG, in 11 OAPS, 65 “non-criteria” OAPS (NOAPS), 31 OAPS carrier, 90 connective tissue disease-RPL (CTD-RPL), 75 unexplained RPL (URPL), 45 thrombotic APS (TAPS) patients, and 81 healthy controls (HCs). Our results showed that aPS/PT IgG/M, aANXA5, aANXA2, aVIM, aβ2GPI-D1, aPE, aPI IgG/M, and aPS IgG were associated with RPL. We found that aPS/PT IgG was positively correlated with the number of “criteria” aPL positivity in APS patients. Importantly, “non-criteria” aPL-positive RPL patients could benefit from the treatment with LMWH and LDA. Combined aPE, aANXA2, aVIM, and aβ2GPI-D1 could distinguish OAPS, NOAPS, OAPS carrier, CTD-RPL, and URPL group from HCs. Our study demonstrates the utility of “non-criteria” aPLs in identifying RPL women with clinical features of OAPS, which is expected to provide tailored treatment management for RPL patients and ultimately improve obstetric outcomes.
Abstract Heart transplantation in children with intellectual disability is a controversial issue. We sought to describe the prevalence and outcomes of heart transplantation in children with intellectual disability and hypothesized that recipients with intellectual disability have comparable short‐term outcomes compared to recipients without intellectual disability. We performed a retrospective cohort analysis of children receiving a first heart‐alone transplant in the UNOS STAR database from 2008 to 2013. Recipients with intellectual disability were compared to those without using chi‐square tests. Kaplan‐Meier curves were constructed for patient and graft survival. Cox proportional hazard models were used to estimate the association between intellectual disability and graft failure and patient survival. Over the study period, 107 children with intellectual disability underwent initial heart transplantation, accounting for 8.9% of first pediatric heart transplants (total=1204). There was no difference in the incidence of acute rejection between groups in the first year after transplant. Mean functional status scores at follow‐up improved in both groups after transplantation, but tended to be lower among children with intellectual disability than children without. Log‐rank tests did not suggest significant differences in graft survival between those with and without intellectual disability during the first 4 years following transplantation. Children with intellectual disability constitute a significant portion of total heart transplants with short‐term outcomes comparable to children without intellectual disability.
Breast cancer survivors often use clues to convey their concerns to their oncologists. The authors conducted a randomized trial of a communication coaching intervention in which 22 female breast cancer survivors were randomized to the coaching and 22 to treatment as usual. They hypothesized that the intervention would increase breast cancer self-efficacy, improve mood, and reduce fears of recurrence. Through a series of ANCOVAs they found that the intervention led to increases in self-efficacy. Changes in self-efficacy predicted changes in anxiety, depression, and womanhood fears. This coaching intervention shows promise but requires additional studies to establish is efficacy and effectiveness.
Introduction In an effort to improve access to and utilization of health care, the Veterans Health Administration (VHA) continues to investigate the effectiveness of video-teleconferencing (VTC) technologies for service delivery. While previous research focused on the efficacy of VTC treatment for post-traumatic stress disorder (PTSD) in Vietnam era veterans, few studies have evaluated the efficacy of this modality and treatment for the Iraq/Afghanistan era veterans. The aim of this randomized clinical trial was to evaluate equivalence between in person and VTC psychotherapy for PTSD in this newer cohort. Methods Veterans of the Iraq/Afghanistan conflict from two VHA hospitals in the United States were recruited and randomized to receive cognitive processing therapy (CPT) for PTSD either in person (IP) or over VTC. Clinician-administered and self-report measures were collected before, during, and after treatment. Results A trend was observed which suggested that CPT over VTC may be equivalent to the treatment delivered in person, as suggested by previous studies. Regardless of treatment, veterans who received the intervention in both conditions reported significant decreases on post-treatment measures. Discussion This study highlighted research and clinical challenges in providing services to the newest veteran generation in general as well as unique challenges with VTC. One complicating factor to the statistical power of this study was a treatment dropout rate twice the original estimate. Factors that could have influenced this high dropout rate are explored.
