Intraoperative hypotension happens in everyday clinical practice. It was suggested to have a strong association with adverse postoperative outcomes. Hypotension prediction index (HPI) was developed to predict intraoperative hypotension (mean arterial pressure

• People experiencing homelessness (PEH) are a vulnerable population during the COVID-19 pandemic due to preexistingcomorbidities, transience, and distrust of the medical system.• Prior work has demonstrated that The Housing First (HF) model has led to more stable housing, increased outpatienttreatment and primary care physician (PCP) visits, and fewer emergency room visits and hospitalizations.• During the COVID-19 emergency response, hotel rooms across California were re-purposed to house PEH.• The Encampment Med Team, a group of volunteer medical students sworn in as Disaster Service Workers, employed agrassroots approach through routine site visits to encampment and street sites in Sacramento.

The growing demand for sodium-ion batteries (SIBs) in commercial applications has made it imperative to meet the commercial requirements. However, SIBs face significant challenges because of their poor cyclability and low reversible capacity compared with their rival lithium-ion batteries (LIBs). To address these challenges, various techniques, design strategies, surface engineering, and structural modifications have been developed to enhance the electrochemical performance of SIBs. This review focuses on recent developments in improving the electrochemical performance and cyclability of novel promising electrode materials for SIBs. We discuss several unique state-of-the-art research studies of the past five years that demonstrated excellent electrochemical performance through effective methodologies, surface modulations, and substitution of novel elements into the structure, and boosted the efficiency of the materials. Furthermore, we propose that it is important to adopt a nuanced approach when designing SIBs. Rather than copying the designs and methods used for LIBs, ideas should be absorbed from them and approaches should be tailored to meet the specific requirements of SIBs. This will enable the development of SIBs that are optimized for their intended applications and will avoid the challenges that have hindered the commercial success of earlier attempts at constructing SIBs. Thus, the key to creating high-performance SIBs is to draw inspiration from the best practices used in LIBs, while simultaneously innovating and developing new approaches tailored to the unique characteristics of SIBs.

Abstract Background Advocacy is a core component of medical professionalism. It is unclear how educators can best prepare trainees for this professional obligation. We sought to assess medical students’ attitudes toward advocacy, including activities and issues of interest, and to determine congruence with professional obligations. Methods A cross-sectional, web-based survey probed U.S. medical students’ attitudes around 7 medical issues (e.g. nutrition/obesity, addiction) and 11 determinants of health (e.g. housing, transportation). Descriptive statistics, Kruskal-Wallis tests, and regression analysis investigated associations with demographic characteristics. Results Of 240 students completing the survey, 53% were female; most were white (62%) or Asian (28%). Most agreed it is very important that physicians encourage medical organizations to advocate for public health (76%) and provide health-related expertise to the community (57%). More participants rated advocacy for medical issues as very important, compared to issues with indirect connections to health (p

Instagram is a popular social networking site for sharing visual content such as photos and videos. Users can "follow," "like," and "comment" on the posts of others. Instagram has become a place for users to constantly compare themselves to others and feel compelled to show oneself in a certain manner due to the platform's emphasis on visual content. The purpose of this research was to investigate whether Instagram users experience regret or social pressure based on their gender. The research examines whether Instagram users adhere to social norms and compare themselves to others on the network, drawing on the theories of social conformity and social comparison. Data was collected from 390 Instagram users through an online survey. Results showed that women use Instagram filters and editing tools more frequently than men, but the reasons for this gender gap require further investigation. Contrary to the hypothesis, the association between time spent on Instagram and social conformity pressure was not stronger for women than for men. Instead, Instagram use frequency played a vital role in shaping the relationship between time spent on the platform and social conformity pressure. According to the study's findings a large proportion of Instagram users, regardless of gender, reported having regret after posting. Our results imply that those who spend more time on Instagram may experience more pressure to adhere to the views and actions of others on the site, with regular use perhaps being a driving factor in this pressure.

Two years since the advent of the COVID-19 pandemic, it is time to discuss the long-term complications post virus infection. We are reporting three autopsy cases from patients who had COVID-19 one to six months before death. All three patients were SARS-CoV-2 negative at admission but expired shortly. At autopsy, the first patient showed subacute diffuse myocardial ischemic injury with microthrombi in pericardial small vessels, whereas the second patient showed catastrophic acute and subacute pulmonary infarctions with hemothorax leading to respiratory failure. The third patient showed subacute severe cerebral infarcts in the left middle cerebral artery region. Our findings suggest the hypercoagulopathy and subsequent vital organ damage may persist beyond the active phase of SARS-CoV-2 infection. It is essential to continue monitoring the COVID-19 patients after recovery, so as to identify those with vital organ injury in a timely manner and to take necessary steps to prevent severe consequences of COVID-19 complications.

Background Immune checkpoint inhibitors (CIs) have revolutionized treatment of advanced melanoma, leading to an emerging population of long-term survivors. Survivors’ quality of life (QOL) and symptom burden are poorly understood. We set out to evaluate symptom burden and QOL in patients with advanced melanoma alive more than 1 year after initiating CI therapy.Methods Cross-sectional surveys, accompanied by chart review of patients with advanced melanoma treated with CIs at Memorial Sloan Kettering Cancer Center, completed therapy, and were alive >1 year after treatment initiation. Surveys were administered between February and August 2018. Surveys included: European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, EuroQOL, items from Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events and Fatigue Severity Scale.Results We included 90 patients. The most common CI regimens were ipilimumab plus nivolumab (53%) and pembrolizumab (41%); most patients (71%) were not treated in clinical trials. Median time from CI therapy initiation was 40 months and from last dose was 28 months. Fatigue was reported by 28%, with higher fatigue scores in women than men; 12% reported difficulty sleeping. Aching joints (17%) and muscles (12%) were fairly common. Level of functioning was generally high. Overall QOL was excellent though 40% reported ‘some or moderate’ problems with anxiety/depression and 31% with pain/discomfort.Conclusions After CI therapy, long-surviving advanced melanoma patients commonly report fatigue but otherwise have moderate symptom burden and good QOL. Ensuring appropriate symptom management will optimize clinical outcomes for these patients.
