Effects of Preoperative Glucocorticoid Use on Patients Undergoing Single-Level Lumbar Fusions: A Retrospective Propensity Score-Matched Registry Study.

Objective Spinal fusions are gaining popularity as a means of treating spinal deformity and instability from a range of pathologies. The prevalence of glucocorticoid use has also increased in recent decades, and their systemic effects are well-documented. Although commonly used in the preoperative period, the effects of steroids on outcomes among patients undergoing spinal fusions are inadequately described.

Obese patients with new onset atrial fibrillation/flutter have higher risk of hospitalization, cardioversions, and ablations.

Obesity significantly increases the risk of developing atrial fibrillation (AF) and atrial flutter (AFL) and evidence from randomized trials indicates that weight loss may reduce the burden of AF/AFL in obese patients; however, the relationship between obesity and healthcare resource utilization in AF/AFL patients is lacking. We sought to assess this relationship in patients with newly diagnosed AF/AFL in a nationally representative cohort of the United States by using the MarketScan® claims database. International Classification of Diseases, Tenth Revision [ICD 10] diagnosis codes were used to select individuals with a new diagnosis of AF/AFL in 2017 and 2018, adjudicate baseline variables and to classify them according to obesity status.

Methoxsalen Inhibits the Acquisition of Nicotine Self-Administration: Attenuation by Cotinine Replacement in Male Rats.

Introduction: Cigarette smoking remains the leading preventable cause of disease and death. Nicotine is the primary reinforcing ingredient in cigarettes sustaining addiction. Cotinine is the major metabolite of nicotine that produces a myriad of neurobehavioral effects.

The underappreciated diversity of bile acid modifications.

The repertoire of modifications to bile acids and related steroidal lipids by host and microbial metabolism remains incompletely characterized. To address this knowledge gap, we created a reusable resource of tandem mass spectrometry (MS/MS) spectra by filtering 1.2 billion publicly available MS/MS spectra for bile-acid-selective ion patterns.

Introduction to Tobacco Cessation and Motivational Interviewing: Evaluation of a Lecture and Case-Based Learning Activity for Medical Students.

Introduction Despite the fact that tobacco use continues to have significant public health impacts, most healthcare providers are not adequately trained to counsel patients on their tobacco use or to provide cessation resources. Although all healthcare providers have a role in providing tobacco cessation assistance, physicians and advanced practice providers are generally the only practitioners able to furnish tobacco cessation medications and bill insurance for their cessation services. Therefore, ensuring these practitioners are properly trained to offer tobacco cessation to their patients is critical to addressing this public health threat.

Olfactory deficit: a potential functional marker across the Alzheimer's disease continuum.

Alzheimer's disease (AD) is a prevalent form of dementia that affects an estimated 32 million individuals globally. Identifying early indicators is vital for screening at-risk populations and implementing timely interventions. At present, there is an urgent need for early and sensitive biomarkers to screen individuals at risk of AD.

Understanding Type 3 Innate Lymphoid Cells and Crosstalk with the Microbiota: A Skin Connection.

Innate lymphoid cells (ILCs) are a diverse population of lymphocytes classified into natural killer (NK) cells, ILC1s, ILC2s, ILC3s, and ILCregs, broadly following the cytokine secretion and transcription factor profiles of classical T cell subsets. Nonetheless, the ILC lineage does not have rearranged antigen-specific receptors and possesses distinct characteristics. ILCs are found in barrier tissues such as the skin, lungs, and intestines, where they play a role between acquired immune cells and myeloid cells.

Mitochondrial deoxyguanosine kinase is required for female fertility in mice.

Mitochondrial homeostasis plays a pivotal role in oocyte maturation and embryonic development. Deoxyguanosine kinase (DGUOK) is a nucleoside kinase that salvages purine nucleosides in mitochondria and is critical for mitochondrial DNA replication and homeostasis in non-proliferating cells. loss-of-function mutations and deletions lead to hepatocerebral mitochondrial DNA deletion syndrome.

Bile salt hydrolase catalyses formation of amine-conjugated bile acids.

Bacteria in the gastrointestinal tract produce amino acid bile acid amidates that can affect host-mediated metabolic processes; however, the bacterial gene(s) responsible for their production remain unknown. Herein, we report that bile salt hydrolase (BSH) possesses dual functions in bile acid metabolism. Specifically, we identified a previously unknown role for BSH as an amine N-acyltransferase that conjugates amines to bile acids, thus forming bacterial bile acid amidates (BBAAs).

Race-Based Variation in the Utilization of Epidural Analgesia in Addition to General Anesthesia for Open Abdominal Aortic Aneurysm Repair in the United States.

Background: Epidural analgesia (EA) is recommended along with general anesthesia (GA) for patients undergoing open abdominal aortic aneurysm repair (AAA) and is known to be associated with improved postoperative outcomes. This study evaluates inequities in using this superior analgesic approach and further assesses the disparities at patient and hospital levels.

Methods: A retrospective analysis was performed using the Vascular Quality Initiative database of adult patients undergoing elective open AAA repair between 2003 and 2022.

Case Report: Successful avoidance of etoposide for primary hemophagocytic lymphohistiocytosis-induced multiple organ dysfunction syndrome using emapalumab.

We describe the case of an infant who presented with simple rhinovirus/enterovirus bronchiolitis whose condition worsened with rapid progression to multiple organ dysfunction syndrome (MODS). The patient was presumed to have either primary or secondary hemophagocytic lymphohistiocytosis (HLH), and treatment was initiated using dexamethasone, anakinra, and intravenous immunoglobulin to modulate the immune system. Due to the organ dysfunction, the use of etoposide was avoided and instead, emapalumab, an interferon gamma antagonist, was administered at a dose of 6 mg/kg.

The Impact of Living Situation on Healthcare Encounters for Individuals With Intellectual Disability.

Introduction The living situation of individuals with intellectual disabilities (ID) has evolved throughout the years and ranges from living at home with family caregivers to group homes to independent living arrangements. Living situations can affect access to care and thus healthcare utilization seen by healthcare encounters for individuals with ID. Methods The researchers conducted a chart review of 112 patients to assess demographics, living situations, and healthcare encounters between 2019 and 2021.

Self-management of chronic, non-communicable diseases in South Asian settings: A systematic mixed-studies review.

Self-management is crucial in mitigating the impacts of a growing non-communicable disease (NCD) burden, particularly in Low and Middle-Income countries. What influences self-management in these settings, however, is poorly understood. We aimed to identify the determinants of self-management in the high NCD region of South Asia and explore how they influence self-management.

Coexpressed -, -, and -Opioid Receptors Modulate Voltage-Gated Ca Channels in Gastric-Projecting Vagal Afferent Neurons.

Opioid analgesics are frequently associated with gastrointestinal side effects, including constipation, nausea, dysphagia, and reduced gastric motility. Though it has been shown that stimulation of opioid receptors expressed in enteric motor neurons contributes to opioid-induced constipation, it remains unclear whether activation of opioid receptors in gastric-projecting nodose ganglia neurons contributes to the reduction in gastric motility and emptying associated with opioid use. In the present study, whole-cell patch-clamp recordings were performed to determine the mechanism underlying opioid receptor-mediated modulation of Ca currents in acutely isolated gastric vagal afferent neurons.

Impact of Didactic Instruction on the Utilization of Point-of-Care Ultrasound in Family Medicine Residents.

Background and Objectives In 2014, the Council of Academic Family Medicine released recommendations for the education of family medicine residents in point-of-care ultrasound (POCUS) curricula for Family Medicine Residency programs. One barrier to resident education in POCUS is the lack of access to equipment. This pilot study evaluates whether introducing didactic education on POCUS within a Family Medicine Residency program, with limited access to equipment, correlated with increased utilization of ultrasound by residents.

Preoperative Chronic Steroid Use is Associated with Increased Incidence of Postoperative Mortality and Limb Loss following Peripheral Arterial Bypass Surgery for Chronic Limb Threatening Ischemia.

Background: Steroids are a commonly prescribed medication in the United States and have been associated with poor surgical and treatment outcomes. The objective of this study is to assess the relationship between chronic steroid use and surgical outcomes of femoropopliteal and femoral-distal bypasses in patients suffering from chronic limb threatening ischemia (CLTI).

Methods: All adult patients undergoing femoropopliteal and femoral-distal bypasses with single segment autologous vein with an indication of CLTI in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) between 2012 and 2021 were stratified between chronic preoperative steroid use (Group I) and no preoperative use (Group II).

Judicial bypass for minors post-.

State laws that require minors seeking abortion care to notify or obtain consent from a parent or other legal guardian are broadly referred to as parental involvement laws. Judicial bypass allows a minor to petition the court to bypass parental involvement. Even before the decision overturned on 24 June 2022, 36 states had at least one parental involvement law, making minor access to abortion care even more complex than adult access.

Octogenarians fare better under local anesthesia for elective endovascular aortic aneurysm repair.

Objective: With an aging patient population, an increasing number of octogenarians are undergoing elective endovascular abdominal aortic aneurysm repair (EVAR) in the United States. Multiple studies have shown that, for the general population, use of local anesthetic (LA) for EVAR is associated with improved short-term and long-term outcomes as compared with performing these operations under general anesthesia (GA). Therefore, this study aimed to study the association of LA for elective EVARs with perioperative outcomes, among octogenarians.
