We conducted a comprehensive literature search across multiple electronic databases, including PubMed, Embase, Cochrane Library, and Web of Science, from inception to November 2024.

Assessment of Contributing Risk Factors Leading to Heart Failure in Patients Who Are Methamphetamine Users.

Background: Methamphetamine abuse is a public health problem across the world, and the cardiovascular system experiences a significant effect on the myocardium over time. Methamphetamine is a common cause of heart failure with preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF). The prevalence and risk factors for HFpEF and HFrEF in this patient population remain unclear.

Characterization of Pancreatic Collagen-Expressing Fibroblasts in Mouse Acute Pancreatitis.

Background And Aims: Pancreatic stellate cells (PSCs) are critical mediators in chronic pancreatitis with an undefined role in acute pancreatitis (AP). PSCs consist of a heterogenous group of cells and are considered interchangeable with pancreatic fibroblasts. This study explored the heterogeneous nature of PSCs by characterizing pancreatic collagen-expressing fibroblasts (PCFs) via lineage tracing in mouse normal and AP pancreas and determining the effect of PCF depletion in AP.

A novel method for expressing and purifying large quantities of functional and stable human voltage-gated proton channel (hH1).

Purifying membrane proteins has been the limiting step for studying their structure and function. The challenges of the process include the low expression levels in heterologous systems and the requirement for their biochemical stabilization in solution. The human voltage-gated proton channel (hH1) is a good example of that: the published protocols to express and purify hH1 produce low protein quantities at high costs, which is an issue for systematically characterizing its structure and function.

In the field of neurosurgery, robotics assist surgeons in pedicle screw placement and vertebral fusion procedures. The purpose of this review is to look at currently used spinal robots available on the market and compare their overall accuracy, cost, radiation exposure, general adverse events, and hospital readmission rates.

Ethnic disparities in HbA1c and hypoglycemia among youth with type 1 diabetes: beyond access to technology, social deprivation and mean blood glucose.

Introduction: The UK national pediatric diabetes audit reports higher HbA1c for children and young people (CYP) with type 1 diabetes (T1D) of Black ethnicity compared with White counterparts. This is presumably related to higher mean blood glucose (MBG) due to lower socioeconomic status (SES) and less access to technology. We aimed to determine if HbA1c ethnic disparity persists after accounting for the above variables.

The Anatomy of Gossip: Dissecting Dynamics and Impacts in Surgical Residency.

Background: Gossip, defined by social scientists as "evaluative talk about an absent third party," is anecdotally pervasive yet poorly understood in surgical residency programs. Gossip is known to have both positive and negative impacts. This study sought to deconstruct the role of gossip in surgical residency and evaluate its impact through the lens of surgical residents.

Characterization of Vaccine-Enhanced Humoral Immune Responses Against Emergent SARS-CoV-2 Variants in a Convalescent Cohort.

Vaccination of COVID-19-convalescent individuals may generate 'hybrid' immunity of enhanced magnitude, durability, and cross-reactive breadth. Our primary goal was to characterize hybrid antibody (Ab) responses in a patient cohort infected with ancestral Wuhan-Hu-1 virus and vaccinated between 6 and 10 months later with the Wuhan-Hu-1-based BNT162b2 mRNA vaccine. We were particularly interested in determining the efficacy of neutralizing Ab responses against subsequently emergent SARS-CoV-2 variants.

Neoadjuvant Chemotherapy for T3 Tumors in the Era of Precision Medicine-Biology Is Still King.

Clinical T3 (cT3) breast cancer (BC) presents a challenge for achieving cosmetically acceptable breast conservation, and neoadjuvant chemotherapy (NAC) is commonly used for cytoreduction in these high-risk cancers. MammaPrint risk-of-recurrence and BluePrint molecular subtyping genomic signatures have demonstrated high accuracy in predicting chemotherapy benefits. Here, we examined the utility of MammaPrint/BluePrint for predicting pathological Complete Response (pCR) rates to NAC among 404 patients diagnosed with cT3 early-stage BC.

Insights into Cancer-Associated Thrombosis Leading Towards Ischemic Stroke.

Stroke leads to significant disability in most patients, whereas cancer elevates the occurrence of stroke. The incidence of cancer-associated stroke (CAS) is projected to rise as a result of improvements in cancer therapies. Various forms of cancer have been demonstrated to be linked to ischemic stroke.

Cellular plasticity and non-small cell lung cancer: role of T and NK cell immune evasion and acquisition of resistance to immunotherapies.

Lung cancer is a leading global cause of mortality, with non-small cell lung cancer (NSCLC) accounting for a significant portion of cases. Immune checkpoint inhibitors (ICIs) have transformed NSCLC treatment; however, many patients remain unresponsive. ICI resistance in NSCLC and its association with cellular plasticity, epithelial-mesenchymal transition (EMT), enhanced adaptability, invasiveness, and resistance is largely influenced by epigenetic changes, signaling pathways, tumor microenvironment, and associated immune cells, fibroblasts, and cytokines.
