Impact of bariatric surgery on liver fibrosis indices among type 2 diabetes patients in a national cohort.

Obesity is related to liver fibrosis, a condition marked by the collection of scar tissue in the liver due to the development of a profibrotic environment, which includes increased hepatocellular death and elevated reactive oxygen species production. The aim of study is to evaluate the effect of bariatric surgery on the association between liver fibrosis indices and obesity. This is a retrospective cohort, evaluating 1205 individuals diagnosed with type 2 diabetes (T2D) and living with obesity, who experienced bariatric surgery.

The trend of atherogenic indices in patients with type 2 diabetes after bariatric surgery: a national cohort study.

Background: Bariatric surgery has profound effects on weight loss, metabolic regulation, and gut hormone modulation, which make it an efficient tool for managing obesity and improving diabetes outcomes.

Objectives: The objective of this study is to evaluate the atherogenic indices, including atherogenic index of plasma (AIP), atherogenic coefficient (AC), Castelli's risk index II (CRI-II), and lipoprotein combine index (LCI) in individuals with type 2 diabetes (T2D) living with excess weight, who have undergone bariatric surgery.

Setting: Three types of surgery including one-anastomosis gastric bypass/mini gastric bypass (OAGB/MGB), sleeve gastrectomy (SG), and Roux-en-Y gastric bypass (RYGB) were performed on patients with obesity and T2D in the period of August 2009 to February 2021 at the Surgical Department of Hazrat-e Rasool Hospital (University Hospital), Tehran, Iran.

The effect of nutrition education based on the Health Belief Model (HBM) on food intake in pregnant Afghan immigrant women: a semi-experimental study.

Background: According to the World Health Organization report, immigrants are at increased risk of malnutrition. Nutritional deficiencies in pregnancy are a public health concern and around 20 to 30 percent of pregnant women suffer from it worldwide. There has not been any investigation about the effect of any intervention on improving nutritional intake in pregnant Afghan immigrant women.

Malignant Hyperthermia.

Objectives: A narrative expert review aiming to summarize the clinical epidemiology and management of critically ill patients with malignant hyperthermia (MH).

Data Sources: Medline searches were conducted to identify relevant articles describing the epidemiology, pathophysiology, and management of MH. Guidelines from key MH organizations were also incorporated into this review.

Myopathic manifestations across the adult lifespan of patients with malignant hyperthermia susceptibility: a narrative review.

Malignant hyperthermia susceptibility (MHS) designates individuals at risk of developing a hypermetabolic reaction triggered by halogenated anaesthetics or the depolarising neuromuscular blocking agent suxamethonium. Over the past few decades, beyond the operating theatre, myopathic manifestations impacting daily life are increasingly recognised as a prevalent phenomenon in MHS patients. At the request of the European Malignant Hyperthermia Group, we reviewed the literature and gathered the opinion of experts to define MHS-related myopathy as a distinct phenotype expressed across the adult lifespan of MHS patients unrelated to anaesthetic exposure; this serves to raise awareness about non-anaesthetic manifestations, potential therapies, and management of MHS-related myopathy.

The mediating role of mentalization and integrative self-knowledge in the relationship between childhood trauma and fear of intimacy.

Introduction: Since intimacy is a fundamental human need within social relationships, and recognizing that a fear of intimacy correlates with various negative consequences, it becomes crucial to examine the origins and factors that contribute to addressing this issue. This research aimed to investigate the mediating roles of mentalization and integrative self-knowledge in the link between childhood trauma and the fear of intimacy.

Methods: Conducted as correlational descriptive research, our study incorporates a total sample of 303 adult women and men participants aged 20 to 50 in Tehran using the convenience sampling method.

Artificial intelligence approaches to the volumetric quantification of glycogen granules in EM images of human tissue.

Skeletal muscle, the major processor of dietary glucose, stores it in myriad glycogen granules. Their numbers vary with cellular location and physiological and pathophysiological states. AI models were developed to derive granular glycogen content from electron-microscopic images of human muscle.

Uncoupling cytosolic calcium from membrane voltage by transient receptor potential melastatin 4 channel (TRPM4) modulation: A novel strategy to treat ventricular arrhythmias.

The current antiarrhythmic paradigm is mainly centered around modulating membrane voltage. However, abnormal cytosolic calcium (Ca) signaling, which plays an important role in driving membrane voltage, has not been targeted for therapeutic purposes in arrhythmogenesis. There is clear evidence for bidirectional coupling between membrane voltage and intracellular Ca.

Non-invasive assessment of sacroiliac joint and lumbar spine positioning in different unilateral sitting postures.

Background: Sacroiliac joint (SIJ) motion has been documented using invasive and noninvasive kinematic techniques. No study has explored SIJ angular positions in functional postures using noninvasive techniques. The purpose of this study was to quantify SIJ positioning among different seated postures in a healthy population.

Presentation of portomesenteric thrombosis after one-anastomosis gastric bypass: Case report.

Introduction: Obesity is a serious situation that leads to non-communicable diseases like diabetes, hypertension, and others. The prevalence of obesity is growing very fast worldwide, so follow the results bariatric surgery, the most effective treatment of obesity, is increasing. Portomesentric vein thrombosis (PMVT) is one of the rare, fatal post-bariatric complications seen most commonly in sleeve gastrectomy and Roux-en-Y gastric bypass.

Video plethysmography for contactless measurement of respiratory rate in surgical patients.

The accurate recording of respiratory rate (RR) without contact is important for patient care. The current methods for RR measurement such as capnography, pneumography, and plethysmography require patient contact, are cumbersome, or not accurate for widespread clinical use. Video Plethysmography (VPPG) is a novel automated technology that measures RR using a facial video without contact.

Restoration of calcium release synchrony: A novel target for heart failure and ventricular arrhythmia.

Myocardial calcium (Ca) signaling plays a crucial role in contractile function and membrane electrophysiology. An abnormal myocardial Ca transient is linked to heart failure and ventricular arrhythmias. At the subcellular level, the synchronous release of Ca sparks from sarcoplasmic Ca release units determines the configuration and amplitude of the global Ca transient.

Muscle Ultrasound Abnormalities in Individuals with RYR1-Related Malignant Hyperthermia Susceptibility.

Background: Variants in RYR1, the gene encoding the ryanodine receptor-1, can give rise to a wide spectrum of neuromuscular conditions. Muscle imaging abnormalities have been demonstrated in isolated cases of patients with a history of RYR1-related malignant hyperthermia (MH) susceptibility.

Objective: To provide insights into the type and prevalence of muscle ultrasound abnormalities and muscle hypertrophy in patients carrying gain-of-function RYR1 variants associated with MH susceptibility and to contribute to delineating the wider phenotype, optimizing the diagnostic work-up and care for MH susceptible patients.

Distinct pathophysiological characteristics in developing muscle from patients susceptible to malignant hyperthermia.

Background: Most patients with malignant hyperthermia susceptibility diagnosed by the in vitro caffeine-halothane contracture test (CHCT) develop excessive force in response to halothane but not caffeine (halothane-hypersensitive). Hallmarks of halothane-hypersensitive patients include high incidence of musculoskeletal symptoms at rest and abnormal calcium events in muscle. By measuring sensitivity to halothane of myotubes and extending clinical observations and cell-level studies to a large group of patients, we reach new insights into the pathological mechanism of malignant hyperthermia susceptibility.

Neuromuscular symptoms in patients with -related malignant hyperthermia and rhabdomyolysis.

Malignant hyperthermia and exertional rhabdomyolysis have conventionally been considered episodic phenotypes that occur in otherwise healthy individuals in response to an external trigger. However, recent studies have demonstrated a clinical and histopathological continuum between patients with a history of malignant hyperthermia susceptibility and/or exertional rhabdomyolysis and -related congenital myopathies. We hypothesize that patients with a history of -related exertional rhabdomyolysis or malignant hyperthermia susceptibility do have permanent neuromuscular symptoms between malignant hyperthermia or exertional rhabdomyolysis episodes.

Muscle calcium stress cleaves junctophilin1, unleashing a gene regulatory program predicted to correct glucose dysregulation.

Calcium ion movements between cellular stores and the cytosol govern muscle contraction, the most energy-consuming function in mammals, which confers skeletal myofibers a pivotal role in glycemia regulation. Chronic myoplasmic calcium elevation ("calcium stress"), found in malignant hyperthermia-susceptible (MHS) patients and multiple myopathies, has been suggested to underlie the progression from hyperglycemia to insulin resistance. What drives such progression remains elusive.

Association Between the FRAIL Scale and Postoperative Complications in Older Surgical Patients: A Systematic Review and Meta-Analysis.

Background: Several frailty screening tools have been shown to predict mortality and complications after surgery. However, these tools were developed for in-person evaluation and cannot be used during virtual assessments before surgery. The FRAIL (fatigue, resistance, ambulation, illness, and loss of weight) scale is a brief assessment that can potentially be conducted virtually or self-administered, but its association with postoperative outcomes in older surgical patients is unknown.

Synchronizing systolic calcium release with azumolene in an experimental model.

Background: Post-defibrillation myocardial contractile dysfunction adversely affects the survival of patients after cardiac arrest. Attenuation of diastolic calcium (Ca) overload by stabilization of the cardiac ryanodine receptor (RyR2) is found to reduce refibrillation after long-duration ventricular fibrillation (LDVF).

Objective: In the present study, we explored the effects of RyR2 stabilization by azumolene on systolic Ca release synchrony and myocardial contractility.

Intravenous dantrolene in hypermetabolic syndromes: a survey of the U.S. Veterans Health Administration database.

Background: Intravenous dantrolene is often prescribed for hypermetabolic syndromes other than the approved indication of malignant hyperthermia (MH). To clarify the extent of and indications for dantrolene use in conditions other than MH, we sought to document current practices in the frequency, diagnoses, clinical characteristics and outcomes associated with dantrolene treatment in critical care settings.

Methods: Inpatients receiving intravenous dantrolene from October 1, 2004 to September 30, 2014 were identified retrospectively in the U.
