A common liver disease affecting nearly 30% of adults worldwide is far more complex than previously understood. Researchers at Mayo Clinic have identified five biologically distinct forms of the condition, each associated with different risks of serious health complications, including heart disease, liver failure, cancer, and the need for a liver transplant. The findings, published in Nature Communications, come from a collaboration between Mayo Clinic and Virginia Tech. Scientists discovered that metabolic dysfunction-associated steatotic liver disease, or MASLD, can develop through several different biological pathways. Some are closely connected to obesity and diabetes, while others appear to be driven by inherited genetic differences.

IntroductionHypertension is a major global health concern and a leading cause of morbidity and mortality [1]. It is estimated that more than 19 million annual deaths are attributed to cardiovascular disease (CVD) worldwide [2]. In Japan, high blood pressure (BP) has been consistently identified as a strong risk factor for the national burden of CVD, in terms of notable incidence, mortality, direct/indirect healthcare costs, and quality-adjusted life years (QALYs) associated with this condition [3, 4]. Although age-specific mean BP declined in Japan over recent decades [5], hypertension remains a critical public health issue, particularly because of the rapid aging population. The proportion of individuals aged ≥65 years is projected to reach approximately 35% by 2040 in Japan [6], highlighting a potentially higher future burden of hypertension in this country. While the prevalence of hypertension increases with age, population aging may offset the benefits of declining BP levels in each age group. As a result, the future burden of hypertension in Japan remains uncertain.

Granulomatosis with polyangiitis (GPA) is a systemic necrotizing granulomatous vasculitis classically involving the upper and lower respiratory tracts and kidneys. Timely diagnosis requires a high index of suspicion for the presenting symptoms. Otolaryngologic manifestations are commonly reported but most often involve the nasal and paranasal sinuses. Sensorineural hearing loss (SNHL) as the sole initial manifestation of GPA is uncommon and may contribute to diagnostic delay. We report a case of a 67-year-old male who presented with rapidly progressive bilateral SNHL that preceded pulmonary and renal manifestations by several months, during which the patient was treated for otitis externa and Eustachian tube dysfunction without improvement. Development of pulmonary symptoms prompted additional workup, which demonstrated markedly elevated cytoplasmic anti-neutrophil cytoplasmic antibody (c-ANCA) and proteinase 3-anti-neutrophil cytoplasmic antibody (PR3-ANCA), raising concern for GPA. Histopathology then confirmed the diagnosis. The patient was treated with high-dose corticosteroids and rituximab with serologic remission; however, his hearing loss was largely irreversible. This case

What if the human brain works in ways that Sigmund Freud began describing more than 130 years ago? A new scientific analysis suggests that some of his ideas about the mind share surprising similarities with one of the most influential theories in modern neuroscience. Published in the scientific journal Entropy, the paper explores connections between Freud's original theories, later developments in psychoanalysis, and a modern approach to brain research known as the prediction paradigm.

At CHEST 2026, Pourshahid argued for matching patients to center-based, hybrid, or virtual pulmonary rehab based on a structured assessment. Arguing the pro side of a debate at the American College of Chest Physicians (CHEST) 2026 Annual Meeting in Phoenix, Omid Pourshahid, MD, MPH, FCCP, Medical Director, Pulmonary Rehabilitation, Temple University Hospital, said pulmonary rehabilitation should be tailored to each patient’s clinical status and barriers to care rather than delivered through a single center-based model.¹The position builds on a long-standing gap in pulmonary rehabilitation uptake. In a retrospective cohort of 197,376 Medicare beneficiaries hospitalized for COPD in 2014, only 2721 (1.5%) initiated pulmonary rehabilitation within 90 days of discharge.² Initiation within the 90-day window was associated with a lower risk of death at 1 year (hazard ratio [HR], 0.63; 95% CI, 0.57-0.69; P <.001).
