Background And Aims: Hyperhomocysteineamia (HHcy) has long been suggested as a risk factor for atherosclerosis. However, the association between HHcy and peripheral arterial disease (PAD) is still controversial. There is a lack of research on this topic in the Chinese population. This study aims to provide further results.
Methods: 240 PAD patients and 240 control subjects were evaluated for both serum total homocysteine levels and ankle brachial indexes (ABIs). Multivariable logistic regression models were used to estimate the association between HHcy and the risk of developing PAD. Interaction and stratified analyses were conducted according to age, sex, smoking status, drinking status, and histories of chronic disease.
Results: The multivariate logistic regression analyses revealed that the risk of PAD was significantly associated with serum homocysteine levels. The interaction analysis showed no interactive role in the association between HHcy and PAD, indicating that homocysteine was associated with PAD independently of classical vascular risk factors.
Conclusions: In conclusion, HHcy is an independent risk factor for PAD in the Chinese Han population. A prospective and randomized clinical trial of homocysteine lowering therapy in the Chinese population is needed to assess the causal nature of the relationship.

Objective: This study investigates the relationship between the albumin-to-creatinine ratio and diabetic retinopathy (DR) in US adults using NHANES data from 2009 to 2016. This study assesses the predictive efficacy of the urinary serum albumin-to-creatinine ratio (UACR/SACR Ratio) against traditional biomarkers such as the serum albumin-to-creatinine ratio (SACR) and urinary albumin-to-creatinine ratio (UACR) for evaluating DR risk. Additionally, the study explores the potential of these biomarkers, both individually and in combination with HbA1c, for early detection and risk stratification of DR.

Background And Aims: Inflammatory bowel disease (IBD) develops in genetically susceptible individuals exposed to certain environmental factors, of which only a few have been established. We aimed to assess whether bariatric surgery (BS) and severe obesity are associated with an increased risk of developing IBD.
Methods: Adults diagnosed with obesity or severe obesity between 2005 and 2020 were identified from the Catalan Health Surveillance System; those diagnosed with IBD prior to the diagnosis of obesity or severe obesity were excluded.

Methods: The study included 40 patients (42 eyes), categorized into non-RD (23 eyes) and RD (19 eyes) groups.
Pharmacologic Management of Heart Failure with Preserved Ejection Fraction (HFpEF) in Older Adults.

There are several pharmacologic agents that have been touted as guideline-directed medical therapy for heart failure with preserved ejection fraction (HFpEF). However, it is important to recognize that older adults with HFpEF also contend with an increased risk for adverse effects from medications due to age-related changes in pharmacokinetics and pharmacodynamics of medications, as well as the concurrence of geriatric conditions such as polypharmacy and frailty. With this review, we discuss the underlying evidence for the benefits of various treatments in HFpEF and incorporate key considerations for older adults, a subpopulation that may be at higher risk for adverse drug events.

Introduction: Therapeutic drug monitoring (TDM) in inflammatory rheumatic diseases (RMDs) is gaining interest. However, there are unresolved questions about the best practices for implementing TDM effectively in clinical settings.
Objective: The primary objective of this study was to evaluate whether early TDM of adalimumab predicts drug survival at 52 weeks in patients with RMDs.
