Introduction: Using the data taken from the National Health and Nutrition Examination Survey (NHANES) database, we explored the relationship between the dietary inflammatory index (DII) and low muscle mass (LMM) in adults.
Methods: We examined 20,424 adults ≥ 20 years old from the 1999-2006 and 2011-2018 NHANES. We hypothesized that the DII is positively associated with the risk of LMM in adults. Regression, subgroup, and restricted cubic spline (RCS) analyses were used to determine the association between the DII and the risk of LMM.
Results: Analyzing the DII as a continuous variable revealed that each unit increase in DII was associated with an 11% increase in the risk of LMM. When categorized by quartile grouping, the analysis indicated that individuals in the highest DII quartile exhibited a 1.78-fold higher risk of LMM compared to those in the lowest quartile (OR = 1.78, 95% CI: 1.45-2.18). The RCS analysis demonstrated that the risk of LMM remained stable for DII below 1.77, but increased sharply for DII of 1.77 or higher. Subgroup analysis further revealed that the impact of DII on LMM risk was more pronounced in individuals with a body mass index (BMI) of 25 kg/m or greater.
Conclusion: It is necessary to adjust the diet according to the DII to reduce the possibility of LMM and to prevent the occurrence of sarcopenia.

Alzheimer's disease (AD) represents a growing global health burden, underscoring the urgent need for reliable diagnostic and prognostic biomarkers. Although several disease-modifying treatments have recently become available, their effects remain limited, as they primarily delay rather than halt disease progression. Thus, the early and accurate identification of individuals at elevated risk for conversion to AD dementia is crucial to maximize the effectiveness of these therapies and to facilitate timely intervention strategies.

Background: Agitation is a common and distressing neuropsychiatric symptom in Alzheimer's disease (AD), affecting up to half of patients and contributing to faster cognitive decline and caregiver burden. Brexpiprazole, a serotonin-dopamine modulator, has been evaluated for this indication, but uncertainties remain regarding its efficacy, safety, and appropriate use in older adults.
Objective: We aimed to assess the efficacy and safety of brexpiprazole for the treatment of agitation in older adults with AD through a systematic review and meta-analysis of randomized controlled trials (RCTs).
Background: Therapeutic management of skin cancer (SC) in the "H-area" of the face is challenging due to the demands of function, cosmesis, and efficacy.
Objective: To evaluate the efficacy and safety of superficial radiotherapy (RT) for skin cancer in the "H-area" of the face and to identify predictors of recurrence.
Methods: Retrospective analysis of patients with SC in the "H-area" of the face treated with superficial RT at the University Hospital of Zurich, Switzerland, between 2010 and 2021.

Background And Purpose: Traumatic subarachnoid hemorrhage (tSAH) is common after head trauma, but its clinical course and optimal imaging follow-up remain unclear. The purpose of this study is to identify predictors of SAH enlargement and neurosurgical intervention in patients with traumatic SAH and to propose a risk-based imaging algorithm.
Materials And Methods: We conducted a retrospective study of 250 patients with traumatic subarachnoid hemorrhage (tSAH) evaluated over a 6-year period.

Background: The relationship between body roundness index (BRI) and low muscle mass (LMM) remains unclear. This study investigated their association in American adults under 60 years.
Methods: This secondary analysis utilized de-identified data from the National Health and Nutrition Examination Survey (NHANES, 2011-2018; n = 8,065 adults <60 years).
