Article Abstract
Background: Several studies have investigated single nucleotide polymorphisms (SNP) in candidate genes associated with susceptibility, severity or outcome in patients with community-acquired pneumonia (CAP) with conflicting results.
Methods: Multi-centre, prospective observational study. We studied 1162 white Spanish patients with CAP and 1413 controls. Severe forms of sepsis were recorded in 325 patients. Subjects were genotyped for the following polymorphisms: TNF -238 and -308, LTA +252, IL6 -174, IL1RN 86bp variable number of tandem repeats and TNFRSF1B+676 (TNFR2 M196R).
Results: No significant differences in genotype or allele frequencies were seen among patients and controls. We did not find any association between TNF, LTA, IL6 and IL1RN polymorphisms with disease severity or outcome. Analysis of 28-day mortality showed a significant difference in the distribution of TNFRSF1B+676 G/T genotypes (p=0.0129). Sequential Kaplan-Meier survival analysis of TNFRSF1B+676 G/T polymorphism showed a protective role of the GT genotype. Cox regression analysis adjusted for age, gender, hospital of origin and comorbidities showed that patients with GT genotypes had lower mortality rates compared to patients with GG or TT genotypes (p=0.02; HR 0.53; 95% CI 0.31-0.90 for 90-day survival; p=0.01; HR 0.41; 95% CI 0.21-0.81 for 28-day survival and p=0.049; HR 0.48; 95% CI 0.23-0.997 for 15-day survival).
Conclusions: Our study does not support a role for the controversial studied polymorphisms of the TNF, LTA, IL6 and IL1RN genes in the susceptibility or outcome of CAP. A protective role of heterozygosity for the functionally relevant TNFRSF1B+676 polymorphism in the outcome of CAP was observed.

Analysis of the hemodynamic impact of coronary plaque morphology in mild coronary artery stenosis.

Objectives: As is well known, plaque morphology plays an important role in the hemodynamics of stenotic coronary arteries, thus their clinic outcomes. However, so far, there has been no research on how the cross-sectional shape of a stenotic lumen affects its hemodynamics. Therefore, this study aims to explore the impact of plaque cross-sectional shape on coronary hemodynamics under mild or moderate stenosis conditions (diameter stenosis degree ≤50 %).

Introduction: It is unclear if intracranial pressure monitoring (ICPM) after open cranial procedures (craniotomy or craniectomy) (OC) for traumatic brain injury is associated with mortality. We hypothesized that ICPM placed early after OC was associated with lower mortality compared to no ICPM or delayed ICPM placement.
Methods: Using 2020-2021 data from the American College of Surgeons Trauma Quality Improvement Program, patients ≥16 y from level 1 and 2 trauma centers who underwent OC were divided into two groups: ICPM placed within 72 h of OC (early) and no ICPM or ICPM placed after 72 h (none/delayed).
Disparities in Rehabilitation Services for Victims of Violence.

Department of Surgery, Boston Medical Center, Boston, Massachusetts; Boston University Chobanian & Avedisian School of Medicine, Boston, Massachusetts.
Introduction: Access to rehabilitation services after a traumatic injury improves functional outcomes. No study has examined the association between injury intent, violent versus nonviolent, and receipt of rehabilitation services after injury.
Materials And Methods: We conducted a retrospective cohort study of injured adult patients admitted to our level I trauma center from January 1, 2014 to December 31, 2021.
Integrating Videoconferencing Therapist Guidance Into Stepped Care Internet-Delivered Cognitive Behavioral Therapy for Child and Adolescent Anxiety: Noninferiority Randomized Controlled Trial.
JMIR Ment Health
January 2025
School of Applied Psychology & Centre for Mental Health, Griffith University, Mt Gravatt, Australia.
Background: Self-guided internet-delivered cognitive behavioral therapy (ICBT) achieves greater reach than ICBT delivered with therapist guidance, but demonstrates poorer engagement and fewer clinical benefits. Alternative models of care are required that promote engagement and are effective, accessible, and scalable.
Objective: This randomized trial evaluated whether a stepped care approach to ICBT using therapist guidance via videoconferencing for the step-up component (ICBT-SC[VC]) is noninferior to ICBT with full therapist delivery by videoconferencing (ICBT-TG[VC]) for child and adolescent anxiety.
Drusen volume as clincial outcome measure in subjects with malattia leventinese.

Department of Ophthalmology, Institute of Clinical Neurosciences of Southern Switzerland (INS), Ospedale Regionale di Lugano, Ente Ospedaliero Cantonale (EOC), Lugano, Switzerland.
Purpose: To assess if drusen volume can serve as structural clinical outcome marker in Malattia Leventinese (ML), and to evaluate whether cones or rods are more affected by its progression, using multimodal imaging and mesopic and two-color scotopic microperimetry.
Methods: This was a prospective monocentric cross-sectional cohort study of participants with genetically confirmed ML. Participants were classified according to morphology.
