The objective of this observational study was to identify multidimensional smoker profiles to aid the development of future tailored treatments for different smoker subtypes. Based on findings in the literature, it was hypothesized that smokers reporting higher levels of novelty seeking/hyperactivity, depressivity, and nicotine dependence would evince greater odds of postintervention smoking than smokers reporting lower symptom levels across these dimensions. Adult regular smokers (N=165) in southwest Germany completed self-report questionnaires assessing psychological and smoking variables and received a pharmacobehavioral intervention. A k-means cluster analysis involving indicators of depressivity, novelty seeking/hyperactivity, and nicotine dependence confirmed the hypothesized smoker profiles. These clusters evinced robustness on cross-validation and predicted smoking on follow-up. Specifically, smokers with depressive, novelty-seeking/hyperactive, and higher dependence profiles evinced significantly greater odds of smoking on follow-up than smokers with low-scoring profiles.

Background/objectives: Both aging and chronic obstructive pulmonary disease (COPD) are strongly associated with changes in the metabolome; however, it is unknown whether there are common aging/COPD metabolomic signatures and if accelerated aging is associated with COPD.
Methods: Plasma from 5704 subjects from the Genetic Epidemiology of COPD study (COPDGene) and 2449 subjects from Subpopulations and intermediate outcome measures in COPD study (SPIROMICS) were profiled using the Metabolon global metabolomics platform (1013 annotated metabolites). Post-bronchodilator spirometry measures of airflow obstruction (forced expiratory volume at one second (FEV)/forced vital capacity (FVC) < 0.

Smoking is a well known risk factor for coronary artery disease (CAD). However, the effects of smoking on gene expression in the blood of CAD subjects in Hungary have not been extensively studied. This study aimed to identify differentially expressed genes (DEGs) associated with smoking in CAD subjects.

Background: The use of heated tobacco products (HTPs) among Korean adults has been steadily increasing since they were first introduced in 2017. It is known that smoking combustible cigarettes (CCs) adversely affects the serum lipid profile and increases the risk of cardiovascular disease. However, the health impacts of HTPs remain under- researched.

Background: To compare the performance of a new-generation cobalt-chromium balloon-expandable bare metal stent with a stainless steel platform for the treatment of iliac occlusive disease.
Methods: Consecutive patients treated for symptomatic iliac occlusive disease between 2014 and 2021 with the cobalt-chromium Dynetic-35 or the stainless steel Dynamic platform were retrospectively evaluated. Outcome measures included technical success, device- or procedure-related death, clinically-driven target lesion revascularization (CD-TLR), primary patency, and major index limb amputation up to 12 months.

Objective: This expert opinion presents provisional guidelines for addressing complications associated with Additively Manufactured Subperiosteal Jaw Implants (AMSJI®) in patients with severe maxillary atrophy. AMSJI®'s custom design, supported by finite element analysis (FEA), allows precise placement that avoids critical anatomical structures and minimizes complications relative to alternative solutions.
Materials And Methods: Data were gathered through firsthand experiences, direct communications, and insights from international workgroup meetings.
