Sex Differences, Menses-Related Symptoms and Menopause in Disorders of Gut-Brain Interaction.

Background: Disorders of gut-brain interaction (DGBI) predominate in women, but little is known about sex differences in menses-related or menopause symptoms.

Methods: Using data from the Rome Foundation Global Epidemiology Survey, we assessed Rome IV DGBI symptoms in individuals in 26 countries who met criteria for ≥ 1 of 5 DGBI: irritable bowel syndrome (IBS), functional dyspepsia (FD), functional constipation (FC), functional diarrhea (FDr), or functional bloating (FB). Participants included pre- and post-menopausal women with DGBI and age-matched men.

Acute Intermittent Porphyria in an Adolescent Patient: Diagnostic and Treatment Challenges.

Acute intermittent porphyria (AIP) is a rare inherited metabolic disorder caused by decreased activity of the enzyme porphobilinogen deaminase in the heme synthesis pathway. This leads to the accumulation of toxic porphyrin precursors, such as porphobilinogen and δ-aminolevulinic acid. Clinical manifestations typically include episodic bouts of severe neurovisceral pain and autonomic dysfunction.

Recommendations for recognizing and diagnosing Acute Hepatic Porphyria in atypical patient populations.

Background: Acute Hepatic Porphyria is a group of four rare genetic but treatable diseases that often go undiagnosed due to its non-specific symptoms, under-recognition of the condition by clinicians, and the lack of access to specialists and appropriate testing. This case-control study investigates the phenotypic and demographic patterns in Acute Hepatic Porphyria (AHP) patients at a tertiary care center (University of California Los Angeles) to update recommendations for recognition and diagnosis of this disease in our community.

Method: A retrospective chart analysis was conducted on 45 patients who were evaluated for AHP, Electronic Medical Record (EMR) data was collected and analyzed to investigate clinical differences and correlations.

A Promising Pathway Toward Mitigation and Eradication of Coronary Artery Disease.

Cardiovascular disease remains the leading cause of death in the United States and globally. Significant advances have been made throughout the history of cardiology and the treatment of this disease; however, these efforts have not halted the alarming statistics. Emerging approaches, such as artificial intelligence applied to cardiac imaging, genetic testing, and genetic silencing, may offer essential additional steps in treating the disease.

Accurate Intramyocardial Hemorrhage Assessment with Fast, Free-running, Cardiac Quantitative Susceptibility Mapping.

Purpose To evaluate the performance of a high-dynamic-range quantitative susceptibility mapping (HDR-QSM) cardiac MRI technique to detect intramyocardial hemorrhage (IMH) and quantify iron content using phantom and canine models. Materials and Methods A free-running whole-heart HDR-QSM technique for IMH assessment was developed and evaluated in calibrated iron phantoms and 14 IMH female canine models. IMH detection and iron content quantification performance of this technique was compared with the conventional iron imaging approaches, R2*(1/T2*) maps, using measurements from ex vivo imaging as the reference standard.

Equity Landscape in Healthcare Quality: A Mixed-Methods Study of Efforts within Surgical Quality Programs.

Background: Addressing equity in healthcare is necessary to improve population health outcomes. In doing so, a requisite level of foundational resources, organization, and processes are needed. Although increasing attention is being devoted to addressing health inequities, the current landscape supporting these efforts remains unknown.

The Use of Next-Generation Sequencing to Assist in the Diagnosis of Atypical Vasculitis.

Vasculitis can be challenging to diagnose, especially when vessels of multiple sizes are affected and manifestations do not classically fit into defined rheumatic disease entities. We present the case of a 58-year-old Caucasian woman who presented with headache and altered mental status, with subsequent left-sided hemiparesis and hemispatial neglect eight days after a dental procedure. She was found to have extensive multi-focal ischemic infarctions secondary to vasculitis affecting multiple intracranial blood vessels.

Importance: Safe and effective long-term treatments for moderate to severe plaque psoriasis are needed.

Objective: To evaluate the long-term safety and efficacy of deucravacitinib through 3 years (week 148) in the randomized POETYK PSO-1, PSO-2, and nonrandomized long-term extension (LTE) trials.

Design, Setting, And Participants: PSO-1/PSO-2 were global, 52-week, randomized, double-blinded phase 3 trials in patients with moderate to severe plaque psoriasis.

Phenotypes and Trajectories of Tobacco-exposed Persons with Preserved Spirometry: Insights from Lung Volumes.

Among tobacco-exposed persons with preserved spirometry (TEPS), we previously demonstrated that different lung volume indices, specifically elevated total lung capacity (TLC) versus elevated ratio of functional residual capacity-to-TLC (FRC/TLC), identify different lung disease characteristics in the COPDGene cohort. Determine differential disease characteristics and trajectories associated with the lung volume indices among TEPS in the SPIROMICS cohort. We categorized TEPS (n=814) by tertiles (low, intermediate, high) of TLC or residual volume-to-TLC (RV/TLC) derived from baseline CT images, and then examined clinical and spirometric disease trajectories in mutually exclusive categories of participants with high TLC without high RV/TLC ([TLC]) versus high RV/TLC without high TLC ([RV/TLC]).

Spatial resolution enhancement using deep learning improves chest disease diagnosis based on thick slice CT.

CT is crucial for diagnosing chest diseases, with image quality affected by spatial resolution. Thick-slice CT remains prevalent in practice due to cost considerations, yet its coarse spatial resolution may hinder accurate diagnoses. Our multicenter study develops a deep learning synthetic model with Convolutional-Transformer hybrid encoder-decoder architecture for generating thin-slice CT from thick-slice CT on a single center (1576 participants) and access the synthetic CT on three cross-regional centers (1228 participants).

The C3-C3aR axis modulates trained immunity in alveolar macrophages.

Complement protein C3 is crucial for immune responses in mucosal sites such as the lung, where it aids in microbe elimination and enhances inflammation. While trained immunity - enhanced secondary responses of innate immune cells after prior exposure - is well-studied, the role of the complement system in trained immune responses remains unclear. We investigated the role of C3 in trained immunity and found that , trained wild-type mice showed significantly elevated pro-inflammatory cytokines and increased C3a levels upon a second stimulus, whereas C3-deficient mice exhibited a blunted cytokine response and heightened evidence of lung injury.

Blood-brain barrier disruption and increased free water are associated with worse cognitive performance in patients with chronic cerebrovascular disease.

Progression of cerebral small vessel disease (CSVD) is associated with cognitive decline. Blood-brain barrier disruption (BBBD) and fluid extravasation to the interstitial space may contribute to progression of white matter hyperintensities (WMH). We hypothesized that increased free water (FW) would colocalize with BBBD and relate to cognitive performance.

ICU nutrition research: did the evidence get better? Remaining sources of bias.

Purpose Of The Review: To assess the quality of recently published (18 months from date of article request) randomized trials/systematic reviews of such trials that addressed the use of nutritional support in critically ill patients.

Recent Findings: Eligible papers were published between October 1, 2022 and April 7, 2024, only enrolled adults, described a comparison of a nutritional intervention to something else, and reported a clinically relevant outcome. Thirteen randomized trials and four systematic reviews of randomized trials were identified.

Stakeholder Perspectives on a Heart Failure With Reduced Ejection Fraction Polypill: A Multi-Center Mixed Methods Study.

Background: A polypill containing all 4 classes of guideline-directed medical therapy for heart failure with reduced ejection fraction (HFrEF) has been proposed to change the heart failure treatment paradigm. The acceptability, appropriateness, and feasibility of a HFrEF polypill-based strategy are unknown. The purpose of this study was to elicit patients' and providers' priorities in the design of HFrEF polypills.

How Well Are Surgical Quality Improvement Projects Planned? Review of 242 Surgical Improvement Efforts Across 5 American College of Surgeons Quality Programs.

Background: Structured preparation is necessary to conduct quality improvement (QI) strategies that are relevant to the problem, feasible, appropriately resourced, and potentially effective. Recent work suggests that improvement efforts are suboptimally conducted. Our goal was to determine how well preparation for surgical QI is undertaken, including detailing the problem, setting project goals, and planning an intervention.

A retrospective analysis using comorbidity detecting algorithmic software to determine the incidence of International Classification of Diseases (ICD) code omissions and appropriateness of Diagnosis-Related Group (DRG) code modifiers.

Background: The mechanism for recording International Classification of Diseases (ICD) and diagnosis related groups (DRG) codes in a patient's chart is through a certified medical coder who manually reviews the medical record at the completion of an admission. High-acuity ICD codes justify DRG modifiers, indicating the need for escalated hospital resources. In this manuscript, we demonstrate that value of rules-based computer algorithms that audit for omission of administrative codes and quantifying the downstream effects with regard to financial impacts and demographic findings did not indicate significant disparities.

A review of intracranial aneurysm imaging modalities, from CT to state-of-the-art MR.

Traditional guidance for intracranial aneurysm (IA) management is dichotomized by rupture status. Fundamental to ruptured aneurysm management is the detection and treatment of subarachnoid hemorrhage, along with securing the aneurysm by the safest technique. On the other hand, unruptured aneurysms first require a careful assessment of natural history versus treatment risk, including an imaging assessment of aneurysm size, location, and morphology, along with additional evidence-based risk factors such as smoking, hypertension, and family history.

Caffeine Use in Huntington's Disease: A Single Center Survey.

Background: Anecdotal evidence suggests paradoxical caffeine overuse in individuals with Huntington's disease (HD). A small retrospective study associated caffeine intake over 190 grams daily to earlier onset of HD symptoms. However, specific data on consumption habits is limited.
