Changes in the running-related injury incidence rate ratio in a 1000-km explorative prospective cohort study involving two unspecific shoe changes

ABSTRACT Introduction: Basketball referees are the authorities responsible for ensuring that rules and regulations are followed and for making decisions. The ability of referees to respond to the physical and physiological demands imposed during the game is essential for good performance on the court. Objective: To understand the context in which health problems faced by basketball referees occur and to outline the epidemiological profile of musculoskeletal injuries. Methods: A prospective cohort study was conducted in which basketball referees were evaluated using a standardized form. The participants were monitored online weekly for 12 weeks using the Oslo Sports Trauma Research Center questionnaire to assess health problems, such as diseases (affecting the respiratory, cardiovascular, digestive or neurological systems) or musculoskeletal injuries (acute or from overuse). Results: The study sample consisted of 78 referees with a mean age of 36.5 (±9.8) years. Most referees (97.4%) found it important to implement a preventive program. In relation to the health problems reported during follow-up, there was an incidence rate of 23.7 injuries per 1000 hours of play (95% CI 19.5 - 27.9) and the mean weekly prevalence of diseases was 3.2 (95% CI 0.4 – 6.0) and of injuries was 17.4 (95% CI 16.5 – 18.3). Conclusion: Through this study, it was possible to conclude that there was an incidence rate of 23.7 injuries per 1000 hours of play (95% CI 19.5 - 27.9) and a mean prevalence of diseases of 3.2 (95% CI 0.4 - 6.0) and musculoskeletal injuries of 17.4 (95% CI 16.5 - 18.3). The most common health problems that affected basketball referees were musculoskeletal overuse injuries of the lower limbs. Level of evidence I; Prospective cohort study .

Second Wave

Objectives: To assess if healthcare workers during the second wave of the COVID-19 pandemic had increased SARS-CoV-2 infection rates following close contact with patients, co-workers and persons outside work with COVID-19. Design: Prospective cohort study. Setting: Public hospital employees in Denmark. Participants: 5985 healthcare workers (88.6% women) who daily on a smartphone reported COVID-19 contact. Main outcome measures: SARS-CoV-2 infection rates defined by the first positive polymerase chain reaction (PCR) test recorded in a register with complete test coverage. Results: 159 positive and 35 996 negative PCR tests for SARS-CoV-2 were recorded during 514 165 person-days of follow-up November 25, 2020 - April 30, 2021. The SARS-CoV-2 infection rate for healthcare workers who during the previous 3-7 days had close contact with COVID-19 patients was 153.7 per 100 000 person-days (0.15% per day) corresponding with an incidence rate ratio of 3.17 (40 cases, 95% CI 2.15 to 4.66) when compared with no close contact with COVID-19 patients. SARS-CoV-2 incidence rate ratios following close contact with co-workers and persons outside work with COVID-19 were 2.54 (10 cases, 95% CI 1.30 to 4.96) and 17.79 (35 cases, 95% CI 12.05 to 26.28). These estimates were mutually adjusted and further adjusted for age, sex, month and number of previous PCR tests. Conclusions: Despite strong focus on preventive actions during the second wave of the pandemic, healthcare workers were still at increased risk of SARS-CoV-2 infection when in close contact with patients with COVID-19. The numbers affected were comparable to the numbers affected following COVID-19 contact outside work. Close contact with co-workers was also a risk factor. This stresses the need for increased focus on preventive actions to secure healthcare workers' health during ongoing and future waves of SARS-CoV-2 and other infections.

ObjectivesTo estimate the incidence of gastroenteritis in individuals in care homes.DesignProspective cohort study.SettingFive participating care homes in North West England, UK.ParticipantsResidents and staff present at the five study care homes between 15 August 2017 and 30 May 2019 (n=268).Outcome measuresWe calculated incidence rates for all gastroenteritis cases per 1000 person-years at risk and per 1000 bed-days at risk. We also calculated the incidence rate of gastroenteritis outbreaks per 100 care homes per year.ResultsIn total 45 cases were reported during the surveillance period, equating to 133.7 cases per 1000 person-years at risk. In residents the incidence rate was 0.62 cases per 1000 bed-days. We observed seven outbreaks in all care homes included in surveillance, a rate of 76.4 outbreaks per 100 care homes per year. 15 stool samples were tested; three were positive for norovirus, no other pathogens were detected.ConclusionsWe found that surveillance of infectious gastroenteritis disease in care homes based on outbreaks, the current general approach, detected a majority of cases of gastroenteritis. However, if policymakers are to estimate the burden of infectious gastroenteritis in this setting using only routine outbreak surveillance data and not accounting for non-outbreak cases, this study implies that the total burden will be underestimated.
