Background And Aims: The prevalence of metabolic dysfunction associated steatotic liver disease (MASLD), formerly known as nonalcoholic fatty liver disease (NAFLD), has become a significant public health concern with an increased atherosclerotic cardiovascular disease risk. This study investigates the impact of NAFLD-related single nucleotide polymorphisms (SNPs) on carotid atherosclerosis development in a Japanese population without diabetes, dyslipidemia, and hypertension.

Methods: The prospective observational study, part of the Kyushu and Okinawa Population Study (KOPS), included 945 participants (median age 55 [47, 63]) without carotid atherosclerosis, increased alcohol intake, diabetes, dyslipidemia, hypertension, or chronic hepatitis at baseline.

Background: Aarskog-Scott syndrome (AAS) is a rare condition with multiple congenital anomalies, caused by hemizygote variants in the gene. Its description was based mostly on old case reports, in whom a molecular diagnosis was not always available, or on small series. The aim of this study was to better delineate the phenotype and the natural history of AAS and to provide clues for the diagnosis and the management of the patients.

Background: This study aimed to describe and compare therapeutic approaches for horses with acute diarrhea in different geographic regions worldwide.

Methods: Clinical information was retrospectively collected from diarrheic horses presented to participating institutions between 2016 and 2020, including fluid therapy on admission, antimicrobial drugs, probiotics, anti-endotoxic medications, anti-inflammatory drugs, gastroprotectants, digital cryotherapy, and toxin-binding agents. Seasonal and geographic differences were investigated.

Introduction: This study evaluated patient-reported outcome measures and reinjury rates in higher-risk adolescents and young adults aged 14-25 years old following Anterior Cruciate Ligament reconstruction using autograft with suture tape augmentation (SA ACLR).

Materials And Methods: We performed a retrospective case series of patients aged 14-25 who underwent SA ACLR by a single surgeon between 2016 and 2020. After a minimum of 2 years of follow-up, data was collected on reinjury and patient reported outcome measures, including Knee Injury and Osteoarthritis Outcome Score (KOOS), Marx Activity Rating Scale (MARS), Single Assessment Numeric Evaluation (SANE), and Visual Analog Pain Scale (VAPS).

Transthyretin amyloidosis (ATTR) is a severe and rare disease characterized by the progressive deposition of misfolded transthyretin proteins, causing irreversible organ damage. Transthyretin amyloidosis can present as a hereditary ATTR or acquired wild-type ATTR form. Genetic testing is critical for determining a hereditary predisposition and subsequently initiating appropriate family screening.

Article Synopsis
  • A multicenter phase 1b study explored the effectiveness and tolerability of combining spartalizumab with various platinum-doublet chemotherapy regimens in treatment-naïve patients with non-small cell lung cancer (NSCLC) that were not selected based on PD-L1 expression.
  • The study found that the maximum tolerated dose for spartalizumab was 300 mg every 3 weeks, and overall response rates to the treatment generally ranged from 51.5% to 57.6%, indicating a good level of efficacy across different chemotherapy combinations.
  • Notably, patients receiving pemetrexed/cisplatin showed the longest median progression-free survival and overall survival compared to other treatment groups, highlighting the potential of this regimen in

Objectives: We conducted a systematic review and meta-analysis to assess the effects of carotenoid supplementation on glycemic indices, and the certainty of evidence.

Methods: A systematic literature search in PubMed, SCOPUS, ISI-Web of Science, and Cochrane Library was conducted from inception up to Jun 17, 2024. Randomized controlled trials (RCTs) investigating the effect of carotenoid supplementation on circulating glycemic parameters were included.

Article Synopsis
  • Osteoporosis is a skeletal disorder leading to increased fracture risk, and when it affects young individuals, it often indicates genetic causes related to early-onset osteoporosis (EOOP).
  • Over 577 patients with primary osteoporosis were studied using next-generation sequencing of 21 bone fragility-related genes, revealing that around 18% had a genetic basis, primarily linked to the LRP5 gene.
  • A rare finding included 17 patients with a variant in the PLS3 gene, suggesting the involvement of dominant X-linked osteoporosis, predominantly affecting males, but also identified severe cases in females, pointing toward possible genetic interactions.

Purpose: Seizure-related homolog protein 6 (SEZ6) is a novel target expressed in small cell lung cancer (SCLC). ABBV-011, a SEZ6-targeted antibody conjugated to calicheamicin, was evaluated in a phase I study (NCT03639194) in patients with relapsed/refractory SCLC. We report initial outcomes of ABBV-011 monotherapy.

Objective: Standing desks present a novel approach to reduce sedentary time in the classroom and address cardiovascular risk factors at an early age. In the context of designing a standing desk study, parents and children were surveyed regarding their perceptions and current use of standing desks and other flexible seating.

Methods: Survey administered from January 31st to February 26th, 2024 to a convenience cohort of 50 parent-child pairs presenting for well or acute care at a pediatrics clinic affiliated with an academic institution (Hershey, Pennsylvania, United States).

Article Synopsis
  • SCN5A gene variants are linked to various cardiac electrical disorders, but they can also result in complex phenotypes like overlap syndromes, which haven't been thoroughly studied.
  • The study analyzed DNA from over 13,500 patients with a focus on those carrying pathogenic SCN5A variants, finding that most were tied to well-defined conditions like Brugada syndrome and long QT syndrome.
  • About 19% of the variants were associated with complex phenotypes, and only a small number (8 out of 9,960 patients) showed a potential link to dilated cardiomyopathies (DCM), suggesting it's a rare association.

Background: Genetic epilepsy diagnosis is increasing due to technological advancements. Although the use of molecular diagnosis is increasing, chromosomal microarray analysis (CMA) remains an important diagnostic tool for many patients. We aim to explore the role and indications of CMA in epilepsy, given the current genomic advances.

Aim: To investigate the associations of the Dietary Approaches to Stop Hypertension (DASH) score with subcutaneous (SAT) and visceral (VAT) adipose tissue volume and hepatic lipid content (HLC) in people with diabetes and to examine whether changes in the DASH diet were associated with changes in these outcomes.

Methods: In total, 335 participants with recent-onset type 1 diabetes (T1D) and type 2 diabetes (T2D) from the German Diabetes Study were included in the cross-sectional analysis, and 111 participants in the analysis of changes during the 5-year follow-up. Associations between the DASH score and VAT, SAT and HLC and their changes were investigated using multivariable linear regression models by diabetes type.

Although intensive induction chemotherapy (IC) remains the standard of care for younger patients with acute myeloid leukemia (AML), hypomethylating agents + venetoclax (HMA/VEN) can lead to durable remission among older patients with nucleophosmin 1 (NPM1) mutations. Whether IC or HMA/VEN is superior in patients aged ≥60 years with NPM1-mutant AML is unknown. We performed an international, multicenter retrospective cohort study of 221 patients (147 IC and 74 HMA/VEN) with previously untreated NPM1-mutant AML.

Osteogenesis Imperfecta (OI) is a clinically and genetically heterogeneous group of diseases characterized by brittle bones. Though genetic mutations in COL1A1 and COL1A2 account for approximately 85-90% of OI cases, there are now more than twenty genes described, responsible for rare forms of OI. Treatment is based on the use of bisphosphonates and though it is well established that they increase lumbar spine (LS) bone mineral density (BMD), the clinical impact on fracture reduction is still debated.
