Project description:Background: After the COVID-19 pandemic reached France in January 2020, a national lockdown including school closures was officially imposed from March 17, 2020, to May 10, 2020. Pediatric intensive care units (PICUs) admit critically ill infants, children and teenagers with severe acute conditions, in particular infectious and traumatic diseases. We hypothesized that PICU admissions would be considerably modified by the lockdown. Aims: The objectives of the study were to describe the type of admissions to French PICUs and to compare the occupation of PICU beds according to local epidemic conditions during the French national lockdown period, compared with the same period the previous year. Methods: We conducted a retrospective multicenter study in 14 French PICUs. All children aged from 7 days to 18 years admitted to one of the 14 participating PICUs over two 3-month period (March 1, 2020, to May 31, 2020 and March 1, 2019, to May 31, 2019) were included. Analysis was based on data extracted from the medicalized information systems program (a national database used in all French hospitals, into which all admissions and their diagnoses are coded for the purpose of calculating hospital funding). Each main diagnosis was reclassified in 13 categories, corresponding to normal PICU admissions. Results: We analyzed a total of 3,040 admissions, 1,323 during the 2020 study period and 1,717 during the same period in 2019. Total admissions decreased by 23% [incidence rate ratio (IRR) 0.77, 95% CI 0.71-0.83, p < 0.001], in particular for viral respiratory infections (-36%, IRR 0.64, 95% CI 0.44-0.94, p = 0.001). Admissions for almost all other diagnostic categories decreased, except intoxications and diabetes which increased, while admissions for cardiac and hemodynamic disorders were stable. Patient age and the sex ratio did not differ between the two periods. Median length of stay in the PICU was longer in 2020 [4 (IQR 2-9) vs. 3 (IQR 1-8) days, p = 0.002] in 2019. Mortality remained stable. Conclusions: In this large national study, we showed a decrease in the number of PICU admissions. The most severe patients were still admitted to intensive care and overall mortality remained stable.

Project description:ObjectivesTo observe the weight change in Chinese youth during a 4-month COVID-19 lockdown, and the association between weight change and mental health, physical activity and sedentary time changes, and dietary habits.DesignA retrospective observational study.SettingsTwo universities located in Zhejiang and Hunan provinces, China.ParticipantsThis study enrolled 12 889 college students whose body weight was measured before the lockdown (1 December 2019-20 January 2020) at the two universities, and reported their weight measured at home or community after the end of the lockdown (1-23 May 2020) via an online follow-up questionnaire.Primary and secondary outcome measuresThe primary outcome was the weight change in Chinese youth during a 4-month lockdown resulting from the COVID-19 pandemic. The secondary outcomes were the relationships of weight change to COVID-19-related stress, depression, anxiety, physical activity and sedentary time changes, and dietary habits.ResultsParticipants' ages ranged from 17 to 27 years (M=19, SD=1) with 80.2% identified as female. The average absolute and relative changes in body weight were 2.6 (95% CI 2.0 to 3.2)) kg and 4.2% (95% CI 4.0% to 4.3%) for men, and 2.1 (1.9 to 2.4) kg and 4.2% (95% CI 3.9% to 4.4%) for women. An increase in overweight and obese individuals according to Asian cut-off points as a demographic percentage by 4.5% and 2.7% and 4.8% and 3.4% in men and women, respectively (P<0.001), was observed. Weight gain was significantly associated with increased sedentary time and an increase in COVID-19-related stress and depression score.ConclusionThe present study's results suggest that the risk of weight gain in Chinese youth during the lockdown increased and that strategies to decrease sedentary time and improve mental health may be warranted to mitigate weight gain during and after the COVID-19 pandemic.

Project description:Background Management of ST-elevated myocardial infarction (STEMI) necessitates rapid reperfusion. Delays prolong myocardial ischemia and increase the risk of complications, including death. The COVID-19 pandemic may have impacted STEMI management. We evaluated the relative volume of hospitalizations and clinical time intervals within a regional STEMI system. Methods 494 patients with STEMI were grouped into pre-lockdown, lockdown and re-opening cohorts. Clinical, temporal and outcome data were collected and compared between groups for both urban and rural patients, receiving primary percutaneous coronary intervention (PCI) and pharmacoinvasive revascularization, respectively. Data was compared to a 10-year historical comparator. Results During pre-lockdown there was 238 cases versus 193 in lockdown; a 19.0% reduction in volume. When lockdown was compared to the median caseload from a 10-year historical cohort, a 19.8% reduction was observed. For patients treated with primary PCI during lockdown, median symptom-to-balloon time increased by 44-minutes [217 (IQR 157-387) vs. 261 (160-659) minutes; p=0.03]; driven by an increase in median symptom-to-door time of 41-minutes [136 (IQR 80-267) vs. 177 (IQR 90-569) minutes; p<0.01]. Only patients transferred from non-PCI facilities demonstrated an increase in door-to-reperfusion time [116 (IQR 93-150) vs. 139 (IQR 100-199) minutes; p<0.01]. More patients had left ventricular dysfunction during the lockdown [35% vs. 44%; p=0.04], but there was no difference in mortality. Conclusion During the COVID-19 lockdown, fewer patients presented with STEMI. Time-to-reperfusion was significantly prolonged and appeared driven predominantly by patient-level and transfer delays. Public education and systems-level changes will be integral to STEMI care during the second wave of COVID-19. Reports from Canadian cardiovascular centers have indicated that the COVID-19 lockdown may have had unintended affects on STEMI care. There is limited Canadian data providing granular details regarding the impact of the COVID-19 lockdown on STEMI care patterns. We present data from a large cardiac care institution that demonstrates patient and hospital transfer level delays in STEMI care during the COVID-19 lockdown. These challenges must be addressed in light of a second wave of COVID-19.

Project description:We investigated whether osteoporotic fractures declined during lockdown, among adults aged 50 years and older. We showed that fewer outpatients attended the Fracture Clinic, for non-hip fractures, during lockdown; in contrast, no change in admissions for hip fractures was observed. This could be due to fewer outdoors falls, during lockdown.PurposeMany countries implemented a lockdown to control the spread of the COVID-19 pandemic. We explored whether outpatient attendances to the Fracture Clinic for non-hip fragility fracture and inpatient admissions for hip fracture declined during lockdown, among adults aged 50 years and older, in a large secondary care hospital.MethodsIn our observational study, we analysed the records of 6681 outpatients attending the Fracture Clinic, for non-hip fragility fractures, and those of 1752 inpatients, admitted for hip fracture, during the time frames of interest. These were weeks 1st to 12th in 2020 ("prior to lockdown"), weeks 13th to 19th in 2020 ("lockdown") and corresponding periods over 2015 to 2019. We tested for differences in mean numbers (standard deviation (SD)) of outpatients and inpatients, respectively, per week, during the time frames of interest, across the years.ResultsPrior to lockdown, in 2020, 63.1 (SD 12.6) outpatients per week attended the Fracture Clinic, similar to previous years (p value 0.338). During lockdown, 26.0 (SD 7.3) outpatients per week attended the Fracture Clinic, fewer than previous years (p value < 0.001); similar findings were observed in both sexes and age groups (all p values < 0.001). During lockdown, 16.1 (SD 5.6) inpatients per week were admitted for hip fracture, similar to previous years (p value 0.776).ConclusionDuring lockdown, fewer outpatients attended the Fracture Clinic, for non-hip fragility fractures, while no change in inpatient admissions for hip fracture was observed. This could reflect fewer non-hip fractures and may inform allocation of resources during pandemic.

Project description:Dental clinics were suspected to be a hotspot for nosocomial transmission of coronavirus disease 19 (COVID-19), yet there has been no clear recommendation about emergency dental care and appropriate personal protective equipment during pandemics. In this paper, we aim to summarize recommendations for (i) patient risk assessment, (ii) patient triage, and (iii) measures to prevent infection of health professionals and nosocomial transmission in dental clinics. The available evidence was collected by performing searches on PubMed, Embase, and Cochrane databases. We reviewed papers on COVID-19, severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), influenza, and related respiratory viral diseases. Legal and ethical frameworks, as well as international (e.g., World Health Organization (WHO)) and national (e.g., public health institutes, dental associations) guidelines were screened to summarize recommendations related to dental emergency care. To assess the patient risk, a questionnaire was developed to classify patients at unknown, high, and very high risk. Patient triage recommendations were summarized in a flow chart that graded the emergency level of treatments (i.e., urgent, as soon as possible, and postpone). Measures to prevent disease transmission based on current evidence were grouped for dental health professionals, dental clinics, and patients. The present recommendations may support health professionals implement preventative measures during the pandemic.

Project description:BackgroundThe purpose of this study was to evaluate the multifaceted impact of the COVID-19 pandemic on dental practices and their readiness to resume dental practice during arduous circumstances.MethodsThe authors distributed an observational survey study approved by The University of Texas Health Science Center at San Antonio Institutional Review Board to dental care practitioners and their office staff members using Qualtrics XM software. The survey was completed anonymously. The authors analyzed the data using R statistical computing software, χ2 test, and Wilcoxon rank sum test.ResultsNearly all participants (98%) felt prepared to resume dental practice and were confident of the safety precautions (96%). Only 21% of dentists felt the COVID-19 pandemic changed their dental treatment protocols, with at least two-thirds agreeing that precautions would influence their efficiency adversely. Although most participants were satisfied with the resources their dental practice provided for support during the pandemic (95%), most were concerned about the impact on their general health and safety (77%) and to their dental practice (90%), found working during the pandemic difficult (≈ 60%), and agreed there are challenges and long-term impacts on the dental profession (> 75%).ConclusionsDental care professionals, although affected by the COVID-19 pandemic and at high risk of developing COVID-19, were prepared to resume dental practice during most challenging circumstances.Practical implicationsThe pandemic has affected dental care practitioners substantially; thus, there is need to formulate psychological interventions and safety precautions to mitigate its impact. Further research should evaluate the long-term effects on dentistry and oral health and interceptive measures for better communication and programming around future challenges.

Project description:BackgroundA reduction of admission for MI has been reported in most countries affected by COVID-19. No clear explanation has been provided.MethodsTo report the incidence of myocardial infarction (MI) admission during COVID-19 pandemic and in particular during national lockdown in two unequally affected French provinces (10-million inhabitants) with a different media strategy, and to describe the magnitude of MI incidence changes relative to the incidence of COVID-19-related deaths. A longitudinal study to collect all MIs from January 1 until May 17, 2020 (study period) and from the identical time period in 2019 (control period) was conducted in all centers with PCI-facilities in northern "Hauts-de-France" province and western "Pays-de-la-Loire" Province. The incidence of COVID-19 fatalities was also collected.FindingsIn "Hauts-de-France", during lockdown (March 18-May 10), 1500 COVID-19-related deaths were observed. A 23% decrease in MI-IR (IRR=0.77;95%CI:0.71-0.84, p<0.001) was observed for a loss of 272 MIs (95%CI:-363,-181), representing 18% of COVID-19-related deaths. In "Pays-de-la-Loire", 382 COVID-19-related deaths were observed. A 19% decrease in MI-IR (IRR=0.81; 95%CI=0.73-0.90, p<0.001) was observed for a loss of 138 MIs (95%CI:-210,-66), representing 36% of COVID-19-related deaths. While in "Hauts-de-France" the MI decline started before lockdown and recovered 3 weeks before its end, in "Pays-de-la-Loire", it started after lockdown and recovered only by its end. In-hospital mortality of MI patients was increased during lockdown in both provinces (5.0% vs 3.4%, p=0.02).InterpretationIt highlights one of the potential collateral damages of COVID-19 outbreak on cardiovascular health with a dramatic reduction of MI incidence. It advocates for a careful and weighted communication strategy in pandemic crises.FundingThe study was conducted without external funding.

Project description:Trying to manage the dramatic coronavirus disease 2019 (COVID-19) infection spread, many countries imposed national lockdown, radically changing the routinely life of humans worldwide. We hypothesized that both the pandemic per se and the consequent socio-psychological sequelae could constitute stressors for Italian population, potentially affecting the endocrine system. This study was designed to describe the effect of lockdown-related stress on the hypothalamic-pituitary-thyroid (HPT) axis in a cohort of young men. A prospective, observational clinical trial was carried out, including patients attending the male infertility outpatient clinic before and after the national lockdown for COVID-19 pandemic. The study provided a baseline visit performed before and a follow-up visit after the lockdown in 2020. During the follow-up visit, hormonal measurements, lifestyle habits and work management were recorded. Thirty-one male subjects were enrolled (mean age: 31.6 ± 6.0 years). TSH significantly decreased after lockdown (p = 0.015), whereas no significant changes were observed in the testosterone, luteinising hormone, follicle-stimulating hormone, estradiol and prolactin serum levels. No patient showed TSH serum levels above or below reference ranges, neither before nor after lockdown. Interestingly, TSH variation after lockdown was dependent on the working habit change during lockdown (p = 0.042). We described for the first time a TSH reduction after a stressful event in a prospective way, evaluating the HPT axis in the same population, before and after the national lockdown. This result reinforces the possible interconnection between psychological consequences of a stressful event and the endocrine regulation.

Project description:ObjectivesTo determine national medium-term trends in dental visits during three COVID-19 emergency declaration periods in Japan and to analyse how these trends varied according to prefectural emergency measures and COVID-19 incidence.Design and settingA retrospective observational study of Japan's dental claims from January 2017 to December 2021.Data sourcesData from a monthly report by the Health Insurance Claims Review and Reimbursement Services (HICRRS) in Japan. HICRRS handles the claims of employer-based health insurance.Data analysisWe determined the number of monthly dental claims nationwide from January 2017 to December 2021 and the percentage change in the number of monthly dental claims based on the difference in the COVID-19 alert level between the three emergency declaration periods in 2020-2021 and the corresponding periods in 2019. Results were analysed using descriptive statistics, multiple regression model, graphical figures, and narrative synthesis.Outcome measuresThe main outcome was the change in the number of dental visits between the emergency declaration periods in 2020-2021 and the corresponding periods in 2019. We also assessed the difference in the number of dental visits based on the COVID-19 alert level.ResultsThe data set included a total of 736 946 088 dental claims. Until the end of 2021, the greatest decrease in monthly dental claims was in April 2020, which was 22.3% lower than that in April 2019. As indicated by the coefficient in the regression model, the percentage change in monthly dental claims decreased by 5.01% (95% CI -8.27 to -1.74) depending on the difference between the prefectures designated as being under special precautions and other prefectures.ConclusionsThe decrease in dental visits was greater during the first state of emergency, ie, April-May 2020, and in prefectures designated as being under special precautions. Further efforts to promote appropriate dental visits at different alert levels are necessary.

Project description:ObjectivesThe current COVID-19 outbreak in conjunction with the need to provide safe dental treatments and the limited knowledge on the efficacy of protective measures has posed dentists into a challenging situation. Therefore, the present article aimed at collecting experiences and recommendations of frontline clinical experts on critical aspects of dental treatment provision during pandemic.Material & methodsFrom a total of 32 European countries, one leading academic expert in Oral and Maxillofacial Surgery or Oral Surgery per country was asked to participate in an anonymous online 10-item survey on COVID-19 covering the topics of safety of dental settings, personal protective equipment (PPE), and patient-related measures to reduce transmission risk. Data collection took place from April 12th to May 22nd, 2020.ResultsA total of 27 experts from different European countries completed the survey. The transmission risk of SARS-CoV-2 in dental settings for aerosol-generating procedures was considered high by all experts except two. For aerosol-free and aerosol-generating procedures, more than 80% of the experts recommended face protection and caps for every single treatment. For aerosol-generating procedures, additional measures (FFP2/FFP3 masks and gowns) were suggested by the vast majority of the experts. To reduce transmission risk, all experts recommended limiting aerosol-generating procedures and reducing the number of patients in waiting areas as well as hand hygiene for the patients.ConclusionThe limitation of aerosol-generating procedures along with the usage of adequate personal protection equipment was considered to be crucial to protect dental healthcare providers and patients, thus reducing the transmission risk of COVID-19.
