Background: The circulation rate and the clinical severity of infections caused by members of the new human rhinovirus C (HRV-C) species remain to be defined.
Objectives: To investigate the epidemiologic and clinical impact of HRV-C strains in a fall outbreak interesting hospitalized patients.
Study Design: HRV species (A-C) were determined by phylogenetic analysis following amplification of two genome regions (5'NCR and VP4/VP2) by RT-PCR. HRV species were correlated with age, respiratory tract involvement, clinical symptoms, and HRV load in respiratory secretions.
Results: During the first week of the period October-November 2008, single HRV infections were associated with 95% of all respiratory syndromes affecting hospitalized patients. Then, HRV infections (single+coinfections) interested about 90% of positive samples until the end of October, when they declined in frequency until reaching about 30% at the end of November. Overall, 104 HRV strains were detected and, of these, 90 could be classified by phylogenetic analysis, as follows: 45 HRV-A, 12 HRV-B, 28 HRV-C, and 5 human enterovirus D strains. HRV-C identity was confirmed by detection of cis-acting replication elements (cre) in 23/23 strains. As for severity of respiratory syndromes, unlike HRV-A and HRV-B strains, HRV-C strains were responsible for a significantly higher rate (p<0.05) of lower respiratory tract infections in the pediatric as compared to adult patient population.
Conclusions: HRV-C strains have been shown to circulate at a rate intermediate between HRV-A and HRV-B strains, showing a greater degree of clinical severity in the pediatric population.

Background: Increasing physical activity levels is a significant unmet need in cancer survivors, and it can likely be enhanced through a better understanding of the interventions developed. Some studies on patient-centered physical activity interventions have shown promising results in increasing daily activity levels among lung cancer survivors. However, the programs present a high heterogeneity, and there is no consensus on the parameters and their effectiveness.

Background: Mental health problems in university students are associated with many negative outcomes, yet there is a gap between need and timely access to help. Single-session interventions (SSIs) are designed to be scalable and accessible, delivering core evidence-based intervention components within a one-off encounter.
Objective: COMET (Common Elements Toolbox) is an online self-help SSI that includes behavioral activation, cognitive restructuring, gratitude, and self-compassion.
Exploring the Users' Perspective of the Nationwide Self-Exclusion Service for Gambling Disorder, "Spelpaus": Qualitative Interview Study.

Department of Clinical Sciences Lund, Faculty of Medicine, Lund University, Lund, Sweden.
Background: Problem gambling and gambling disorder cause severe social, psychiatric, and financial consequences, and voluntary self-exclusion is a common harm reduction tool used by individuals with gambling problems.
Objective: The aim of this study was to explore users' experience of a novel nationwide, multioperator gambling self-exclusion service, "Spelpaus," in Sweden and to inform stakeholders and policy makers in order to improve harm reduction tools against gambling problems.
Methods: Semistructured interviews were conducted with 15 individuals who reported self-perceived gambling problems and who had experience of having used the self-exclusion service Spelpaus in Sweden.
The effect of Lewy body (co-)pathology on the clinical and imaging phenotype of amnestic patients.

Lewy body (LB) pathology is present as a co-pathology in approximately 50% of Alzheimer's disease (AD) dementia patients and may even represent the main neuropathologic substrate in a subset of patients with amnestic impairments. However, the degree to which LB pathology affects the neurodegenerative course and clinical phenotype in amnestic patients is not well understood. Recently developed α-synuclein seed amplification assays (αSyn-SAAs) provide a unique opportunity for further investigating the complex interplay between AD and LB pathology in shaping heterogeneous regional neurodegeneration patterns and clinical trajectories among amnestic patients.

Morbilliform eruptions, which are a clinical reaction pattern characterized by erythematous macules and papules coalescing into patches that cover most of the skin surface, are one of the most common cutaneous findings in the inpatient setting. In the hospital setting, most causes are benign and due to low-risk drug exanthems; however, morbilliform eruptions may also be a sign of high-risk diseases, including Stevens-Johnson syndrome/toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms/drug-induced hypersensitivity syndrome, acute generalized exanthematous pustulosis, and graft-versus-host disease. Proper identification of the etiology and risk stratification of a morbilliform eruption is critical to ensure proper management and optimize patient outcomes.
