We aimed to investigate whether the implementation of personal protective measures against coronavirus disease 2019 reduced the transmission of influenza-like illnesses.

We followed 758 international students from 95 countries located in five continents from October 2020 to March 2021. Their frequency of wearing masks, social distancing, washing hands, and avoiding crowded places as well as their reported cases of influenza-like illnesses were examined. We used Kaplan-Meier analysis to compare the occurrence of symptoms of influenza-like illnesses among participants who adhered with those who did not adhere to the personal protective measures.

From October 2020 to March 2021, 139 (18%) students reported symptoms of influenza-like illnesses. The survival analysis showed that students who frequently wore face masks, exercised physical distancing, and disinfected their hands had a reduced risk of influenza-like illnesses. We found a two-fold increased risk of influenza-like illnesses among participants who did not implement all the personal protective measures as compared with those who adhered to the measures (Hazard ratio=2.16, 95%CI=1.53-3.05, P<0.001).

Our findings suggest that personal protective measures with high feasibility and high acceptability could be implemented during influenza epidemics to reduce transmission.

Coronavirus Disease 2019 (COVID-19) has presented an unprecedented challenge for delivering clinical research. The use of technology-assisted data collection for clinical research is desirable for many practitioners, but the acceptability of use in the general population has not been assessed. The aim of the study was to assess attitudes towards using technology-assisted remote methods in the delivery of clinical research in the UK and to understand the barriers to taking part in research with respect to both remote assessments and traditional research methods across different age ranges.

The study was conducted as an online anonymous survey with a 4-part questionnaire, between August 2020 and December 2020. Participants living in the UK aged 18years and above were eligible to take part.

A total 351 completed the survey and are included in the data analysis. In all age groups, participants identified that use of online assignments, video calls and telephone calls would make them more likely to take part in clinical research. Overall, the largest barrier to taking part in research was time commitments and timing of the appointment. COVID-19 has had a small, positive influence on the confidence of using technology in the general population.

The study found that there is a large interest in taking part in research using online, telephone and video call appointments, which could facilitate research delivery in light of ongoing COVID-19-related restrictions and also improve the accessibility and inclusivity of research.

Online tools are increasingly utilized in clinical trial recruitment. A/B testing is an effective technology used in political campaigns and commercial marketing to improve contributions or sales. However, to our knowledge, A/B has not been described in the context of clinical trial recruitment.

Two A/B testing experiments were implemented on the recruitment website of the Study To Understand Fall Reduction and Vitamin D in You (STURDY), a response-adaptive, two-stage, randomized controlled trial. Commercial A/B platforms randomized web-users to different versions of the trial's website landing page; Experiment 1 included two infographic versions and Experiment 2 included three video versions. We compared web-user engagement metrics between each version and the original landing page. We determined the effect of each version compared to the original landing page on the likelihood of a web-user to (1) request more information about the trial, (2) complete a screening visit, or (3) enroll in the trial.

A tCT02166333 Trial Registration Number NCT02166333 Trial Register ClinicalTrials.gov.Sexual abuse of boys and men is a public health problem that has received relatively little attention from clinical scholars and researchers. Given unique pathways for development of and recovery from trauma-related emotional distress, sexual abuse survivors who identify as men may require distinct psychosocial interventions to engage in formal mental health care and assist in symptom reduction. This paper describes the rationale for and methodology of a randomized controlled trial comparing the effectiveness of Motivational Interviewing (MI) versus MI with affirmative care (MI-AC) for sexual and gender minority men who have been sexually traumatized. This study is designed to randomly assign 356 participants to either condition of six online group sessions delivered by two trained peers with lived experience of sexual trauma. Assessments will be conducted at baseline, post-treatment, 60- and 120-day follow-up. The primary hypotheses are that participants assigned to MI-AC, compared to those in MI only, will report reduced symptoms of depression and increased levels of engagement in formal mental health treatment. Additional hypotheses relate to secondary outcome variables, including post-traumatic stress disorder, suicidality, and substance use.
Pediatric disability prevalence has increased to 17.8% in recent years. This youth population faces a range of individual, social, and environmental level barriers to a healthy lifestyle. This is particularly concerning because this population is at a higher risk of obesity and lifestyle-related morbidity and mortality. Therefore, A-ONE An Accessible and Online Nutrition & Exercise Program was designed to provide a comprehensive and holistic online program for youth with physical disabilities.

A-ONE will offer two individualized fitness workouts and one accessible cooking session per week for 16-weeks. In addition, A-ONE will offer one social-mentoring session per week. All programming (4 sessions per week) will occur during after-school hours. The program will be offered 6 times during the 2-year grant period, enrolling 10 youth per cohort, for a total of 60 youth with physical disabilities. Outcomes to be examined include physical activity, fruit and vegetable consumption, independent meal preparatiing disabilities. This program represents a sustainable and scalable way to remove barriers and improve the trajectories of health among youth with a physical disability.
The COVID-19 pandemic has had a profound impact on the mental health of people around the world. Anxiety related to infection, stress and stigma caused by the forced changes in daily life have reportedly increased the incidence and symptoms of depression, anxiety disorder and obsessive-compulsive disorder. Under such circumstances, telepsychiatry is gaining importance and attracting a great deal of attention. However, few large pragmatic clinical trials on the use of telepsychiatry targeting multiple psychiatric disorders have been conducted to date.

The targeted study cohort will consist of adults (>18years) who meet the DSM-5 diagnostic criteria for either (1) depressive disorders, (2) anxiety disorders, or (3) obsessive-compulsive and related disorders. Patients will be assigned in a 11 ratio to either a "telepsychiatry group" (at least 50% of treatments to be conducted using telemedicine, with at least one face-to-face treatment [FTF] within six months) or an "FTF group" (all treatments to be conducted FTF, with no telemedicine). Both groups will receive the usual treatment covered by public medical insurance. buy Navitoclax The study will utilize a master protocol design in that there will be primary and secondary outcomes for the entire group regardless of diagnosis, as well as the outcomes for each individual disorder group.

This study will be a non-inferiority trial to test that the treatment effect of telepsychiatry is not inferior to that of FTF alone. This study will provide useful insights into the effect of the COVID-19 pandemic on the practice of psychiatry.

jRCT1030210037, Japan Registry of Clinical Trials (jRCT).The contact poison VX (O-ethyl S-(2-diisopropylaminoethyl) methylphosphonothioate) is a chemical warfare agent that is one of the most toxic organophosphorus compounds known. Its primary mechanism of toxic action is through the inhibition of acetylcholinesterase and resultant respiratory paralysis. The majority of work on VX has thus concentrated on its potent anticholinesterase activity and acute toxicity, with few studies investigating potential long-term effects. In this report we describe the effects of VX in aggregating rat brain cell cultures out to 28 days post-exposure. Cholinesterase activity was rapidly inhibited (60 min IC50 = 0.73 +/- 0.27 nM), but recovered towards baseline values over the next four weeks. Apoptotic cell death, as measured using caspase-3 activity was evident only at 100 μM concentrations. Cell type specific enzymatic markers (glutamine synthase, choline acetyltransferase and 2',3'-cyclic nucleotide 3'-phosphodiesterase) showed no significant changes. Total Akt levels were unchanged, while an increased phosphorylation of this protein was noted only at the highest VX concentration on the first day post-exposure. In contrast, significant and delayed (28 days post-exposure) decreases were noted in vascular endothelial growth factor (VEGF) levels, a protein whose reduced levels are known to contribute to neurodegenerative disorders. These observations may indicate that the long-term effects noted in some survivors of nerve agent intoxication may be due to VX-induced declines in brain VEGF levels.Air pollution has significant health effects worldwide, and airborne particles play a significant role in these effects. Ultrafine particles (UFPs) have an aerodynamic diameter of 0.1 μm or less, can penetrate deep into the respiratory tree, and are more toxic due to their large specific surface area, which should adsorb organic compounds. The aim of this study is to show the toxicological effects of UFPs with high organic content at low dose on BEAS-2B cells through at air-liquid interface (ALI) exposure using a Vitrocell® technology and a miniCAST (Combustion Aerosol Standard) generator. In conjunction with this approach, chemical analysis of particles and gas phase was performed to evaluate the presence of polycyclic aromatic hydrocarbons (PAHs). Chemical analyses confirmed the presence of PAHs in UFPs. With this experimental setup, exposure of the BEAS-2B cells induced neither cytotoxicity nor mitochondrial dysfunction. However, an increase of oxidative stress was observed, as assessed through Nrf2, NQO1, HO-1, CuZnSOD, MnSOD, and Catalase gene expression, together with significant induction of genes related to xenobiotic metabolism CYP1A1 and CYP1B1.
