METHODS: The clinical data of 135 patients with mGGN-type lung adenocarcinoma who received surgical treatment in our hospital from January 2018 to December 2022 were selected from our hospital's medical record database for retrospective analysis...

Powerful, workflow-agnostic and interactive visualisation is essential for the ad hoc, human-in-the-loop workflows typical of cryo-electron tomography (cryo-ET). While several tools exist for visualisation and annotation of cryo-ET data, they are often integrated as part of monolithic processing pipelines, or focused on a specific task and offering limited reusability and extensibility. With each software suite presenting its own pros and cons and tools tailored to address specific challenges, seamless integration between available pipelines is often a difficult task...

BACKGROUND: Caring for a child with cerebral palsy (CP) could negatively affect the Health-Related Quality of Life (HRQOL) of the mothers who are usually the primary caregivers. To the best of our 'knowledge, there is a dearth of information on the HRQOL of primary caregivers of children with CP in Ethiopia. Therefore, this study aimed to investigate caregivers' HRQOL and factors associated with it in Gondar and Bahir Dar Cities, Northwest Ethiopia, 2022. METHODS: A community-based cross-sectional study was conducted among primary caregivers of Children with CP from April 20 to June 20, 2022, in Gondar and Bahir Dar cities...

PURPOSE: Myasthenia gravis (MG) is a chronic autoimmune disease caused by neuromuscular junction (NMJ) dysfunction. Our current understanding of MG's inflammatory component remains poor. The systemic inflammatory response index (SIRI) presents a promising yet unexplored biomarker for assessing MG severity. This study aimed to investigate the potential relationship between SIRI and MG disease severity. PATIENTS AND METHODS: We conducted a retrospective analysis of clinical data from 171 MG patients admitted between January 2016 and June 2021...

INTRODUCTION: Cognitive impairment (CI) is a common complication of end-stage renal disease (ESRD) that is associated with structural and functional changes in the brain. However, whether a joint structural and functional alteration pattern exists that is related to CI in ESRD is unclear. METHODS: In this study, instead of looking at brain structure and function separately, we aim to investigate the covariant characteristics of both functional and structural aspects...

AIMS: To explore the effectiveness of interventions to enhance patient participation in shared decision-making in wound care and tissue viability. BACKGROUND: Caring for people living with a wound is complex due to interaction between wound healing, symptoms, psychological wellbeing and treatment effectiveness. To respond to this complexity, there has been recent emphasis on the importance of delivering patient centred wound care and shared decision-making to personalise health care...

INTRODUCTION: Some studies in both children and adults have shown a mortality benefit for the use of low titer group O whole blood (LTOWB) compared to component therapy for traumatic resuscitation. Although LTOWB is not widely available at pediatric trauma centers, its use is increasing. We hypothesized that in children who received whole blood after injury, the proportion of whole blood in relation to the total blood product resuscitation volume would impact survival. METHODS: The trauma database from a single academic pediatric level 1 trauma center was queried for pediatric (age < 18 years) recipients of LTOWB after injury (years 2015-2022)...

INTRODUCTION: Whole blood (WB) resuscitation is increasingly used at trauma centers. Prior studies investigating outcomes in WB versus component-only (CO) resuscitation have been limited by small cohorts, low volumes of WB resuscitation, and unbalanced CO resuscitation. This study aimed to address these limitations using data from a high-volume Level I trauma center, which adopted a WB-first resuscitation paradigm in 2018. We hypothesized that the resuscitation method, WB or balanced CO, would have no impact on patient mortality...

Geographic disparities in teen birth rates in the U.S. persist, despite overall reductions over the last two decades. Research suggests these disparities might be driven by spatial variations in social determinants of health (SDOH). An alternative view is that "place" or "geographical context" affects teen birth rates so that they would remain uneven across the U.S. even if all SDOH were constant. We use multiscale geographically weighted regression (MGWR) to quantify the relative effects of geographical context, independent of SDOH, on county-level teen birth rates across the U...

BACKGROUND: While multiple studies have investigated the relationship between metabolic syndrome (MetS) and its related traits (fasting glucose, triglyceride, HDL cholesterol, blood pressure, waist circumference) and DNA methylation, our understanding of the epigenetic mechanisms in MetS remains limited. Therefore, we performed an epigenome-wide meta-analysis of blood DNA methylation to identify differentially methylated probes (DMPs) and differentially methylated regions (DMRs) associated with MetS and its components using two independent cohorts comprising a total of 2,334 participants...

PURPOSE: This study aims to explore the contribution of differentially expressed programmed cell death genes (DEPCDGs) to the heterogeneity of serous ovarian cancer (SOC) through single-cell RNA sequencing (scRNA-seq) and assess their potential as predictors for clinical prognosis. METHODS: SOC scRNA-seq data were extracted from the Gene Expression Omnibus database, and the principal component analysis was used for cell clustering. Bulk RNA-seq data were employed to analyze SOC-associated immune cell subsets key genes...

BACKGROUND: Cardiovascular disease is the major cause of morbidity and mortality, particularly in type 2 diabetes mellitus (T2DM). Novel markers of insulin resistance and progression of atherosclerosis include the triglycerides and glucose index (TyG index), the triglycerides and body mass index (Tyg-BMI) and the metabolic score for insulin resistance (METS-IR). Establishing independent risk factors for in-hospital death and major adverse cardiac and cerebrovascular events (MACCE) in patients with myocardial infarction (MI) remains critical...

Obesity increases the morbidity and mortality of traumatic brain injury (TBI). Detailed analyses of transcriptomic changes in the brain and adipose tissue were performed to elucidate the interactive effects between high-fat diet-induced obesity (DIO) and TBI. Adult male mice were fed a high-fat diet (HFD) for 12 weeks prior to experimental TBI and continuing after injury. High-throughput transcriptomic analysis using Nanostring panels of the total visceral adipose tissue (VAT) and cellular components in the brain, followed by unsupervised clustering, principal component analysis, and IPA pathway analysis were used to determine shifts in gene expression patterns and molecular pathway activity...

BACKGROUND: The population aging trend and the shortage of elderly care workers require the long-term care profession to become more attractive. However, the professional attractiveness among long-term care workers has yet to be extensively studied. This study aims to identify the factors that influence the attractiveness of the long-term care profession for nursing home (NH) care workers.. METHODS: A cross-sectional study was conducted in more than 50 NHs. Perception of professional attractiveness among long-term care workers and potential associated factors were measured using the Attractive Work Questionnaire (AWQ) and structural instruments including the Fraboni Scale of Ageism (FSA) and the Maslach Burnout Inventory (MBI)...

BACKGROUND AND PURPOSE: Ischemic stroke disrupts functional connectivity within the brain's resting-state networks (RSNs), impacting recovery. This study evaluates the effects of NEH (Norepinephrine and Hydralazine), a cerebral perfusion augmentation therapy, on RSN integrity in a hyper-acute canine stroke model. MATERIALS AND METHODS: Fifteen adult purpose-bred mongrel canines, divided into treatment and control (natural history) groups, underwent endovascular induction of acute middle cerebral artery occlusion (MCAO)...

Several microbial genomes lack textbook-defined essential genes. If an essential gene is absent from a genome, then an evolutionarily independent gene of unknown function complements its function. Here, we identified frequent nonhomologous replacement of an essential component of DNA replication initiation, a replicative helicase loader gene, in Vibrionaceae . Our analysis of Vibrionaceae genomes revealed two genes with unknown function, named vdhL1 and vdhL2 , that were substantially enriched in genomes without the known helicase-loader genes...

A person-centered approach to advance care planning is recognized as a fundamental need, yet its routine implementation remains a challenge across disparate settings, such as prisons. The purpose of this study was to gain the perspectives of people who are incarcerated about advance care planning. Four focus groups were conducted with people living in 1 men's and 1 women's state prison (n = 26). Handwritten field notes were taken, transcribed, deidentified, and verified before the completion of independent thematic analysis by 2 experienced qualitative researchers...

BACKGROUND: Patients undergoing macroscopically curative resection for distal cholangiocarcinoma (DCC) have high recurrence rates and poor prognoses. This study aimed to investigate the impact of surgical margin status on survival and recurrence after resection of DCC, specifically focusing on microscopic residual tumor (R1) and its relationship to local recurrence. PATIENTS AND METHODS: This was a retrospective analysis of patients who had undergone pancreaticoduodenectomy (PD) for DCC between 2005 and 2021...

Cardiac hypertrophy (CH) is an adaptive response to maintain cardiac function; however, persistent stress responses lead to contractile dysfunction and heart failure. Although inflammation is involved in these processes, the mechanisms that control cardiac inflammation and hypertrophy still need to be clarified. The NLRP3 inflammasome is a cytosolic multiprotein complex that mediates IL-1β production. The priming step of NLRP3 is essential for increasing the expression of its components and occurs following NF-κB activation...

AIM: Protein intake is an important component in retaining muscle mass, especially among older people. This study examined the relationship between total protein intake and/or the distribution of protein intake in each meal and appendicular muscle mass, using data from the National Health and Nutrition Survey (NHNS) in Japan. METHODS: Data from the NHNS were re-analyzed in this study. We used data from a one-day dietary record, physical examination, and lifestyle questionnaire completed by 1766 participants aged over 60 years...
