The novel coronavirus (SARS-CoV-2) has rapidly developed into a global epidemic. To control its spread, countries have implemented non-pharmaceutical interventions (NPIs), such as school closures, bans of small gatherings, or even stay-at-home orders. Here we study the effectiveness seven NPIs in reducing number new infections, which was inferred from reported cases COVID-19 using semi-mechanistic Bayesian hierarchical model. Based on data first epidemic wave n = 20 (i.e., United States,...
Abstract Background The novel coronavirus (SARS-CoV-2) has rapidly evolved into a global epidemic. To control its spread, countries have implemented non-pharmaceutical interventions (NPIs), such as school or border closures, while others even enforced complete lockdowns. Here we study the impact of NPIs in reducing documented cases COVID-19. Documented case numbers are selected because they essential for decision-makers area health-policy when monitoring and evaluating current mechanisms....
The risk of Mycobacterium tuberculosis (Mtb) transmission can be high in crowded clinics. We developed a spatiotemporal model airborne Mtb based on the Wells-Riley equation. collected environmental, clinical and person-tracking data South African clinic during COVID-19, when community or surgical masks were compulsory ventilation was increased. matched person movements with records to identify location infectious TB patients. modeled concentration doses (quanta) estimated individual...
Background Growing evidence suggests an important contribution of airborne transmission to the overall spread Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), in particular via smaller particles called aerosols. However, school children SARS-CoV-2 remains uncertain. The aim this study was assess respiratory infections and association with infection control measures schools using a multiple-measurement approach. Methods findings We collected epidemiological (cases Disease 2019...

The COVID-19 pandemic renewed interest in airborne transmission of respiratory infections, particularly congregate indoor settings, such as schools. We modeled risks tuberculosis (caused by Mycobacterium , Mtb ) and SARS-CoV-2) South African, Swiss Tanzanian secondary estimated the infection with Wells-Riley equation, expressed median 2.5% 97.5% quantiles (credible interval [CrI]), based on ventilation rate duration exposure to infectious doses (so-called quanta). computed air change...
Abstract Background Using a multiple-measurement approach, we examined the real-world effectiveness of portable HEPA air filtration devices (air cleaners) in school setting. Methods We collected data over 7 weeks during winter 2022/2023 2 Swiss secondary classes: environmental (CO2, particle concentrations), epidemiologic (absences related to respiratory infections), audio (coughing), and molecular (bioaerosol saliva samples). crossover design, compared concentrations, coughing, risk...
To control the COVID-19 pandemic, countries around world have implemented non-pharmaceutical interventions (NPIs), such as school closures or stay-at-home orders. Previous work has estimated effectiveness of NPIs, yet without examining variation in NPI across countries. Based on data from first epidemic wave [Formula: see text] countries, we estimate country-specific differences NPIs via a semi-mechanistic Bayesian hierarchical model. Our estimates reveal substantial between indicating that...
ObjectivesTo compare the prevalence of SARS-CoV-2 and other respiratory viruses in saliva bioaerosols between two winters model probability virus detection classroom air for different viruses.MethodsWe analyze saliva, air, cleaner filter samples from studies conducted Swiss secondary schools (age 14-17 years) over seven weeks during 2021/22 2022/23. Two bioaerosol sampling devices HEPA filters cleaners were used to collect airborne particles five classrooms. Daily pooled each device before...
IntroductionHuman mobility was considerably reduced during the COVID-19 pandemic. To support disease surveillance, it is important to understand effect of on transmission.AimWe compared role first and second wave in Switzerland by studying link between daily travel distances effective reproduction number (
Background The COVID-19 pandemic challenged healthcare systems, particularly in settings with high infectious disease burden. We examined the postpandemic long-term impacts of on tuberculosis (TB) services at anti-retroviral therapy (ART) clinics lower-income countries. Methods Using standardised online questionnaires, we conducted a cross-sectional site survey among ART providing TB Africa and Asia from July to September 2023 (site-level information number diagnoses tests). Results Of 45...
Background Work stress affects individual health and well-being. These negative effects could be mitigated through regular monitoring of employees’ stress. Such becomes even more important as the digital transformation economy implies profound changes in working conditions. Objective The goal this study was to investigate association between computer mouse movements work field. Methods We hypothesized that is associated with a speed-accuracy trade-off movements. To test hypothesis, we...
Abstract Aims To analyse glycaemic patterns of professional athletes with type 1 diabetes during a competitive season. Materials and Methods We analysed continuous glucose monitoring data 12 male cyclists exercise, recovery sleep on days exercise ( CE ) non‐competitive NCE ). assessed whether differences exist between associations dysglycaemia. Results The mean glycated haemoglobin was 50 ± 5 mmol/mol (6.7 0.5%). cycled 280.8 28.1 (entire season 332.6 18.8 days). Overall, time in range...
In a recent working paper, Herby et al. conduct systematic review and meta-analysis of the effects lockdowns on COVID-19 mortality. Based their results, they conclude that "lockdowns have had little to no public health effects" should be rejected out hand as pandemic policy instrument" (p. 2). These strong conclusions quickly been taken up by media. Here, we would like comment paper al., thereby raising concerns regarding subject meta-analysis. these concerns, argue lacks methodological...
Introduction HIV replication leads to a change in lymphocyte phenotypes that impairs immune protection against opportunistic infections. We examined current as an independent risk factor for tuberculosis (TB). Methods included people living with from 25 European cohorts 1983–2015. Individuals <16 years or previous TB were excluded. Person-time was calculated enrolment (baseline) the date of diagnosis last follow-up information. used adjusted Poisson regression and general additive models....
Tuberculosis (TB) is the leading cause of death among people with HIV and a major global health challenge. Subclinical cardiovascular manifestations TB are poorly documented in high burden countries.
Abstract The information contained in investor sentiment has up to now hardly been used for portfolio optimization, although theoretical works demonstrate that it should not be neglected and already shown contain exploitable on future returns volatility. Employing the approach of Copula Opinion Pooling, we explore how regarding international stock markets can directly incorporated into optimization procedure. We subsequently show exploited by a trading strategy takes account medium-term...
Abstract Background Using a multiple-measurement approach, we examined the real-world effectiveness of portable HEPA-air filtration devices (air cleaners) in school setting. Methods We collected environmental (CO 2 , particle concentrations), epidemiological (absences related to respiratory infections), audio (coughing), and molecular data (bioaerosol saliva samples) over seven weeks during winter 2022/2023 two Swiss secondary classes. cross-over study design, compared concentrations,...
Postbariatric hypoglycaemia (PBH) is an increasingly recognized complication of bariatric surgery, but its effect on daily functioning remains unclear. In this randomized, single-blind, crossover trial we assessed driving performance in patients with PBH. Ten active drivers PBH (eight females, age 38.2 ± 14.7 years, body mass index 27.2 4.6 kg/m2 ) received 75 g glucose to induce the late postprandial period and aspartame leave glycaemia unchanged, two different occasions. A simulator was...
