Article Abstract

Background: Recent genome-wide association studies (GWAS) and a meta-analysis of GWAS for atopic dermatitis (AD) have identified some AD genetic loci in European and Japanese populations.

Objective: To investigate whether some novel susceptibility loci are associated with AD in the Chinese Han population.

Methods: We first selected eight novel susceptibility loci to replicate in 2,205 AD patients and 2,116 healthy controls using the Sequenom platform. Data were analyzed with PLINK 1.07 software.

Results: We found that rs12634229 (3q13.2), rs7927894 (11p13.5) and rs878860 (11p15.4) showed a slight association with AD (P = 0.012, P = 0.033, P = 0.020, respectively); rs6780220 (3p21.33) was preferentially related to AD with keratosis pilaris, but did not reach the threshold of significance after correction. The frequency of rs7927894 allele T was significantly different between AD patients with a positive and negative family history of atopy.

Conclusion: The loci rs7927894 (11p13.5) are related to AD with a positive family history of atopy in Chinese Han population, providing novel insight into the genetic pathogenesis of AD.

The origin and phylogenetic distribution of symbiotic associations between nodulating angiosperms and nitrogen-fixing bacteria have long intrigued biologists. Recent comparative evolutionary analyses have yielded alternative hypotheses: a multistep pathway of independent gains and losses of root nodule symbiosis vs. a single gain followed by numerous losses.

Evaluating the quality, feasibility and patient satisfaction of medication history taking by telephone for patients with scheduled admissions: a pilot study.

Int J Clin Pharm

September 2025

Heidelberg University, Medical Faculty Heidelberg / Heidelberg University Hospital, Internal Medicine IX - Department of Clinical Pharmacology and Pharmacoepidemiology, Cooperation Unit Clinical Pharmacy, Im Neuenheimer Feld 410, 69120, Heidelberg, Germany.

Introduction: Medication history taking at hospital admission is still prone to errors. Despite numerous quality improvement initiatives, new strategies to improve medication history taking are still sought and evaluated. Unfortunately, the gold standard research methodology for evaluation is resource-intensive, as it requires each patient to complete two medication history interviews.

To identify clinical and demographic predictors associated with the timing of transition from psoriasis (PsO) to psoriatic arthritis (PsA), and to compare the characteristics of patients with concurrent PsO-PsA onset versus those with prolonged transition. A multi-center, observational study was conducted using data from the Turkish League Against Rheumatism (TLAR) network including PsA patients fulfilling CASPAR criteria. Patients were categorized into two groups: Group 1 (concurrent PsO and PsA onset within ± 1 year) and Group 2 (prolonged transition to PsA, > 1 year after PsO).

Background The prognostic value of baseline visual emphysema scoring at low-dose CT (LDCT) in lung cancer screening cohorts is unknown. Purpose To determine whether a single visual emphysema score at LDCT is predictive of 25-year mortality from all causes, chronic obstructive pulmonary disease (COPD), and cardiovascular disease (CVD). Materials and Methods In this prospective cohort study, asymptomatic adults aged 40-85 years with a history of smoking underwent baseline LDCT screening for lung cancer between June 2000 and December 2008.

Purpose: We aimed to investigate allergic sensitization and associated factors in pediatric patients with selective immunoglobulin A deficiency (SIgAD) and to evaluate differences between allergic and nonallergic groups.

Methods: We analyzed 110 patients (aged 4-18 years) diagnosed with SIgAD at Çam and Sakura City Hospitals, Istanbul, between 2021 and 2024. Their demographic, clinical, and laboratory data were assessed.
