BACKGROUND: The American Joint Replacement Registry (AJRR) Total Joint Risk Calculator uses demographic and clinical parameters to provide risk estimates for 90-day mortality and 2-year periprosthetic joint infection (PJI). The tool is intended to help surgeons counsel their Medicare-eligible patients about their risk of death and PJI after total joint arthroplasty (TJA). However, for a predictive risk model to be useful, it must be accurate when applied to new patients; this has yet to be established for this calculator...

Short-term mechanical support by veno-arterial extracorporeal membrane oxygenation (VA ECMO) is more and more applied in patients with severe cardiogenic shock. A major shortcoming of VA ECMO is its variable, but inherent increase of left ventricular (LV) mechanical load, which may aggravate pulmonary edema and hamper cardiac recovery. In order to mitigate these negative sequelae of VA ECMO, different adjunct LV unloading interventions have gained a broad interest in recent years. Here, we review the whole spectrum of percutaneous and surgical techniques combined with VA ECMO reported to date...

Auxetic materials, which possess a negative Poisson's ratio (NPR), have been a hot topic in materials science research. Through atomistic simulations, we theoretically rediscover a few novel two-dimensional (2D) VA-nitride (VA-N) binary compounds with δ-phosphorene-like structures. The structures in the δ-phase (except for δ-PN) exhibit better stability in terms of energy, thermodynamics, and mechanics with respect to their counterparts in the α- and β-phases. The structures in the δ-phase show semiconducting behaviors with direct band gaps falling in the visible light region...

National trends suggest that less than one in four patients experiencing in-hospital cardiac arrest (IHCA) in the United States survive to discharge. This is especially relevant as the rates of IHCA are expected to rise in the years to come. Only a modest upward trend in survival to discharge among patients with IHCA over the past decade warrants evaluation of novel ideas to improve outcomes postcardiopulmonary resuscitation. One such idea is that the use of veno-arterial-extracorporeal membrane oxygenation (VA-ECMO) to augment standard advanced cardiac life support algorithm in patients with an identifiable and reversible cause of cardiac arrest would improve survival to discharge...

We evaluated the prevalence of visual impairment (VI) and blindness among Chinese adults in the Singapore Chinese Eye Study (SCES, 2009-2011), and compared the trends with the Tanjong Pagar Survey, Singapore (TPS), conducted a decade earlier. The SCES comprised of 3,353 Chinese adults aged ≥40 years (response rate, 72.8%). Participants underwent standardized examinations, including measurements of presenting, and best-corrected visual acuity (VA). Bilateral VI (VA < 20/40 to ≥20/200) and blindness (VA < 20/200) were defined based on the United States definition (better-seeing eye)...

Moral injury in veterans with posttraumatic stress disorder includes symptoms of guilt and shame, and these symptoms are often not responsive to evidence-based mental health treatments. Clergy provide a pathway for relieving the guilt and shame. However, there is a long history of mistrust between clergy and mental health clinicians and not enough Veterans Health Administration chaplains to meet this need. The goal of this study was to gather qualitative interview data from relevant stakeholders regarding whether and how Veterans Affairs (VA) mental health clinicians and community clergy could collaborate to address moral injury issues such as guilt and shame in veterans being treated for posttraumatic stress disorder...

The visual performance of a reference group (RG) using diffuser filters was compared to a cataract-diagnosed group (CatG). Measurements of straylight (SL) parameter, photopic contrast sensitivity (CS), and visual acuity (VA) were carried out in both groups. Before the analysis, the performance of the instruments used for this purpose was tested. The RG was comprised of three healthy, young eyes (25-30 years old) while 59 subjects (aged 50-80 years old) with lens opacities were recruited for the CatG. Six diffuser conditions were tested in the RG...

BACKGROUND: Efforts to reduce mortality from esophageal adenocarcinoma (EA) have focused on screening and surveillance of Barrett's esophagus (BE). AIMS: We sought to determine the frequency of prior diagnosis of BE in patients with EA and to evaluate the impact of a prior BE diagnosis on mortality in EA patients. METHODS: This was a retrospective cohort study of patients diagnosed with EA in the VA during 2002-2016. We compared the distributions of EA stage and receipt of treatment between EA patients with and without a prior BE diagnosis and used Cox proportional hazards models to compare mortality risk (all-cause and cancer specific) unadjusted and adjusted for stage and treatment to assess their impact on any survival differences...

Despite widespread use of cognitive behavioral therapy (CBT) in clinical practice, its mechanisms with respect to brain networks remain sparsely described. In this study, we applied tools from graph theory and network science to better understand the transdiagnostic neural mechanisms of this treatment for depression. A sample of 64 subjects was included in a study of network dynamics: 33 patients (15 MDD, 18 PTSD) received longitudinal fMRI resting state scans before and after 12 weeks of CBT. Depression severity was rated on the Montgomery-Asberg Depression Rating Scale (MADRS)...
