Behavioral addictions (internet, gaming and gambling) were substantially inter-correlated, and all were associated with problematic use of social media in unadjusted analyses.

Social media use is associated with other addictive behaviors and mental distress. While factors of causality remain to be studied, these insights can motivate healthcare professionals to assess social media habits, for example in individuals suffering from issues concerning gambling, gaming or mental health.

Chronic obstructive pulmonary disease (COPD) is associated with multiple psychosocial and behavioral factors. Prior research suggests that mind-body interventions may support the development and maintenance of healthy behaviors and improve health-related quality-of-life in such patients. We sought to qualitatively explore cognitive, psychosocial, and behavioral changes in patients with COPD who participated in two different mind-body interventions compared to an education control.

We analyzed semi-structured qualitative exit interviews from a prospective, randomized pilot trial (N = 123) investigating 12-weeks of Tai Chi (TC) vs. mind-body breathing (MBB) vs. education (EDU) control in patients with moderate-severe COPD. TC involved traditional movements, that integrate meditative breathing, while MBB focused mainly on meditative breathing techniques alone. Interviews were audio-recorded and transcribed verbatim. Qualitative analysis of randomly selected transcripts was performed by two independent review), and psychological well-being (particularly relaxation, emotion regulation and decreased reactivity). Compared to MBB, those in TC shared more intention to continue with self-care behaviors, physical activity self-efficacy, and improved flexibility. All three groups, including EDU, noted increased social support and knowledge of disease. Those in EDU, however, had fewer mentions of processes related to behavior change, and less concrete changes in neurocognitive, psychological, and physical function domains.

Mind-body interventions including meditative breathing may impact behavior-related neurocognitive and emotional factors that improve self-care management and support positive behavioral changes in patients with COPD.

Timely knowledge of which influenza vaccine brands are procured and where is of interest to inform site-selection for brand-specific influenza vaccine effectiveness (VE) studies. Vaccine procurement is a key determinant of brand availability. We therefore sought to understand how the procurement for seasonal influenza vaccine in Europe is organized, how this drives brand availability and how procurement data could enable to determine brand availability pre-season.

Structured telephone interviews were conducted with 15 experts in 16 European countries between 2017 and 2019 to collect information on the influenza vaccine procurement systems. Sources of (brand-specific) procurement data were identified and assessed on public accessibility. Vaccine type and brand availability and timelines were determined for the 2019-20 season to understand how procurement systems drive brand availability and diversity.

Four main types of procurement systems for seasonal influenza vaccination campaigns were identified natiocurement data for prospective site-selection for brand-specific VE studies is limited.

At the country-level, brand diversity is generally lower for countries with national public tenders than for countries with regional public tenders or direct purchase. In only a few countries, procurement data at the brand level is both publicly available and timely. Therefore the usefulness of procurement data for prospective site-selection for brand-specific VE studies is limited.Many researchers have studied the relationship between the biological functions of proteins and the structures of both their overall backbones of amino acids and their binding sites. A large amount of the work has focused on summarizing structural features of binding sites as scalar quantities, which can result in a great deal of information loss since the structures are three-dimensional. Additionally, a common way of comparing binding sites is via aligning their atoms, which is a computationally intensive procedure that substantially limits the types of analysis and modeling that can be done. In this work, we develop a novel encoding of binding sites as covariance matrices of the distances of atoms to the principal axes of the structures. This representation is invariant to the chosen coordinate system for the atoms in the binding sites, which removes the need to align the sites to a common coordinate system, is computationally efficient, and permits the development of probability models. buy APR-246 These can then be used to both better understand groups of binding sites that bind to the same ligand and perform classification for these ligand groups. We demonstrate the utility of our method for discrimination of binding ligand through classification studies with two benchmark datasets using nearest mean and polytomous logistic regression classifiers.Human norovirus (NoV) is the leading cause of acute viral gastroenteritis and a major source of foodborne illness. Detection of NoV in food and environmental samples is typically performed using molecular techniques, including real-time reverse transcription polymerase chain reaction (RT-PCR) and less frequently, nested real-time PCR. In this study, we conducted a controlled comparison of two published NoV detection assays a broadly reactive one-step real-time RT-PCR and a two-step nested real-time PCR assay. A 20% human fecal suspension containing a genogroup II human NoV was serially diluted, genome extracted, and subjected to amplification using the two assays compared via PCR Units. Additional amplicon confirmation was performed by dot blot hybridization using digoxigenin (DIG)-labeled oligonucleotide probes. Both assays displayed similar amplification standard curves/amplification efficiencies; however, the nested assay consistently detected one log10 lower virus. Dot blot hybridization improved the detection limit of the nested real-time PCR by one log10 NoV genome copies but impaired the detection limit of the one-step real-time RT-PCR by one log10 NoV genome copies.
