Patients with pulmonary fibrosis (PF) often experience long waits before getting a correct diagnosis, and this delay in reaching specialized care is associated with increased mortality, regardless of the severity of the disease. Early diagnosis and timely treatment of PF can potentially extend life expectancy and maintain a better quality of life. Crackles present in the recorded lung sounds may be crucial for the early diagnosis of PF.

The unexplained association between infection and autoimmune disease is strongest for hepatitis C virus-induced cryoglobulinemic vasculitis (HCV-cryovas). To analyze its origins, we traced the evolution of pathogenic rheumatoid factor (RF) autoantibodies in four HCV-cryovas patients by deep single-cell multi-omic analysis, revealing three sources of B cell somatic mutation converged to drive the accumulation of a large disease-causing clone. A method for quantifying low-affinity binding revealed recurring antibody variable domain combinations created by V(D)J recombination that bound self-immunoglobulin G (IgG) but not viral E2 antigen.

Laparoscopic cholecystectomy is a widely performed procedure, with securing the cystic duct being a critical step to prevent bile leakage. Traditional metal clips are commonly used, but alternative methods, such as non-absorbable polymer clips, absorbable clips, sutures, and ultrasonic shears, are also utilized. This systematic review and meta-analysis evaluates the safety and efficacy of various cystic duct securing techniques.

Endogenous C-type natriuretic peptide offsets the pathogenesis of steatohepatitis, hepatic fibrosis, and portal hypertension.

PNAS Nexus

January 2025

Faculty of Medicine and Dentistry, William Harvey Research Institute, Barts and The London, Queen Mary University of London, Charterhouse Square, London EC1M 6BQ, United Kingdom.

Metabolic dysfunction-associated steatotic liver disease (MASLD), hepatic fibrosis, and portal hypertension constitute an increasing public health problem due to the growing prevalence of obesity and diabetes. C-type natriuretic peptide (CNP) is an endogenous regulator of cardiovascular homeostasis, immune cell reactivity, and fibrotic disease. Thus, we investigated a role for CNP in the pathogenesis of MASLD.

Dysregulation of renin-angiotensin-aldosterone system (RAAS) often leads to hypertension and severe cardiorenal complications. Although RAAS-targeted therapies have proven effective, it remains yet optimal in reducing cardiovascular events. The aim of this study was to evaluate the efficacy and safety of angiotensin receptor neprilysin inhibitor (ARNI) compared to control in patients with hypertension.

Refractive surgery, which includes techniques such as Laser-Assisted In Situ Keratomileusis (LASIK), Photorefractive Keratectomy (PRK) and Small Incision Lenticule Extraction (SMILE), has revolutionized ophthalmology by offering advanced solutions for vision correction. However, the choice of the technique to be used in the individual patient is highly dependent on a thorough preoperative evaluation. This retrospective study aims to investigate how preoperative parameters, including corneal thickness, topography, and refraction, affect long-term post-operative clinical outcomes.

Autologous haematopoietic stem cell transplantation (AHSCT) is a treatment option for relapsing forms of multiple sclerosis (MS) that are refractory to disease-modifying therapy (DMT). AHSCT after failure of high-efficacy DMT in aggressive forms of relapsing-remitting MS is a generally accepted indication, yet the optimal placement of this approach in the treatment sequence is not universally agreed upon. Uncertainties also remain with respect to other indications, such as in rapidly evolving, severe, treatment-naive MS, progressive MS, and neuromyelitis optica spectrum disorder (NMOSD).

Patient-reported health status is an important assessment of patients with heart failure, but current approaches have substantial methodological and analytical limitations. Changes in the Kansas City Cardiomyopathy Questionnaire (KCCQ) are commonly presented as a measure of the effect of drugs and devices, most often as the between-group difference in population means or as the odds of showing threshold changes of 5, 10, 15, and 20 points. However, the presentation of mean differences is based on statistical assumptions that are routinely violated in most trials.

Introduction: The choice between cemented and cementless fixation in primary elective total hip arthroplasty (THA) remains a subject of ongoing debate. However, comparisons between the two are subject to limited adjustments for patient characteristics, diagnoses, and surgical factors, as well as by limited outcome time endpoints. Our study aimed to compare the effect of femoral fixation on safety and implant survival outcomes in matched patients.

Kisspeptin and Neurokinin B: roles in reproductive health.

Physiol Rev

January 2025

Department of Investigative Medicine, Imperial College London, Hammersmith Hospital, London, United Kingdom.

Kisspeptin and neurokinin B (NKB) play a key role in several physiological processes including in puberty, adult reproductive function including the menstrual cycle, as well as mediating the symptoms of menopause. Infundibular kisspeptin neurons, which co-express NKB, regulate the activity of gonadotropin releasing hormone (GnRH) neurons, and thus the physiological pulsatile secretion of GnRH from the hypothalamus. Outside of their hypothalamic reproductive roles, these peptides are implicated in several physiological functions including sexual behavior and attraction, placental function, and bone health.

SMARCA4 regulates the NK-mediated killing of senescent cells.

Sci Adv

January 2025

MRC Laboratory of Medical Sciences (LMS), Du Cane Road, London W12 0NN, UK.

Induction of senescence by chemotherapeutic agents arrests cancer cells and activates immune surveillance responses to contribute to therapy outcomes. In this investigation, we searched for ways to enhance the NK-mediated elimination of senescent cells. We used a staggered screen approach, first identifying siRNAs potentiating the secretion of immunomodulatory cytokines to later test for their ability to enhance NK-mediated killing of senescent cells.
