Background Many studies examined the spread of SARS-CoV-2 within populations using seroprevalence. Healthcare workers are a high-risk population due to patient contact, and studies are needed to examine seroprevalence of SARS-CoV-2 antibodies among healthcare workers. Our study investigates the seroprevalence of anti-SARS-CoV-2 antibodies among staff at primary healthcare institutions in Prishtina, and factors associated with seroprevalence. Methods We carried out a cross-sectional survey including SARS-CoV-2 serological testing and questionnaires with primary healthcare workers from primary healthcare facilities in the Prishtina, the capital city of Kosovo. We calculated prevalence of anti-SARS-CoV-2 antibodies, and of self-reported positive PCR test among primary healthcare workers, as well as crude and adjusted ORs for explanatory factors. Results Eighty-three of the healthcare workers (17.47%) tested positive for SARS-CoV-2 antibodies IgG or IgM, while 231 (48.63%) either had antibodies or a previous positive PCR test. Odds of seropositivity were affected by male gender (OR 2.08, 95% CI 1.20, 3.61), and infected family members (OR 3.61, 95% CI 2.25, 5.79) of healthcare workers. Higher education, being part of larger families and having infected family members gave higher odds of positive PCR test and seropositivity. Other healthcare workers had lower odds of positive PCR test and seropositivity than physicians. Conclusion Over 17% of healthcare workers were seropositive for SARS-CoV-2 antibodies and close to half of them were either seropositive or PCR self-reported positive test. Several factors are associated with decreased and increased odds for such outcomes. These findings should be explored further and addressed to Kosovo policy makers, and assist them to intensify vaccination efforts, and maintain control measures until we achieve herd immunity.

OBJECTIVE: To assess the association of the gender of the delivering physician and the odds of performing cesarean delivery. DATA SOURCES: CINAHL, ClinicalTrials.gov, Cochrane Library, PubMed, Scopus and Web of Science from the first year of records through May 2020. METHODS OF STUDY SELECTION: We included studies that reported odds ratios (OR), or data allowing the calculation of ORs, for cesarean delivery performed by female and male delivering physicians. We also included studies that reported the preference of physicians for performing cesarean deliveries. TABULATION, INTEGRATION, AND RESULTS: Independent data extraction was carried out by at least two researchers. Standard inverse-variance random effects meta-analysis was used to generate overall ORs. Finally, in two separate meta-analyses, we analyzed 15 studies containing clinical data for 1,269,625 births, and 11 studies containing data for the preference for delivery mode of 4,911 obstetricians. Both the crude and adjusted odds of a cesarean delivery were lower for those performed by female physicians (crude OR 0.75, 95% CI 0.68–0.84, τ2=0.029, adjusted OR 0.74, 95% CI 0.65–0.85, τ2=0.031). We also found that female physicians had a lower preference for cesarean delivery in both crude and adjusted analysis (crude OR 0.59, 95% CI 0.36–0.96, I2=77%, adjusted OR 0.58, 95% CI 0.40–0.84, I2=67%). CONCLUSION: Female physicians are less likely to perform cesarean delivery and less likely to prefer it. This was observed across different health systems and populations.

In the view of the first anniversary of COVID-19, this article focuses on the first COVID-19 case in Kosovo, a 22-year-old woman who came from abroad. COVID-19 has become a major threat to the health of the youngest population in Europe. We also considered the efficacy of restrictive measures, such as lockdowns, in Kosovo.

Mass vaccination initiatives are underway worldwide, and a considerable percentage of the world’s population is now vaccinated. This study examined the association of COVID-19 deaths per 1000 cases with a fully vaccinated population. The global median deaths per 1000 cases were 15.68 (IQR 9.84, 25.87) after 6 months of vaccinations and 11.96 (IQR 6.08, 20.63) after 12 months. Across 164 countries, we found significant variations in vaccination levels of populations, booster doses, and mortality, with higher vaccine coverage and lower mortality in high-income countries. Several regression models were performed to test the association between vaccination and COVID-19 mortality. Control variables were used to account for confounding variables. A 10-percentage-point increase in vaccination was associated with an 18.1% decrease in mortality after 6 months (95%CI, 7.4–28.8%) and a 16.8% decrease after 12 months (95%CI, 6.9–26.7%). A 10-percentage-point increase in booster vaccination rates was associated with a 33.1% decrease in COVID-19 mortality (95%CI, 16.0–50.2%). This relationship is present in most analyses by country income groups with variations in the effect size. Efforts are needed to reduce vaccine hesitancy while ensuring suitable infrastructure and supply to enable all countries to increase their vaccination rates.

ObjectiveThe aim of this study is to determine the odds of caesarean section in all births in teaching hospitals as compared with non-teaching hospitals.SettingOver 3600 teaching and non-teaching hospitals in 22 countries. We searched CINAHL, The Cochrane Library, PubMed, sciELO, Scopus and Web of Science from the beginning of records until May 2020.ParticipantsWomen at birth. Over 18.5 million births.InterventionCaesarean section.Primary and secondary outcome measuresThe primary outcome measures are the adjusted OR of caesarean section in a variety of teaching hospital comparisons. The secondary outcome is the crude OR of caesarean section in a variety of teaching hospital comparisons.ResultsIn adjusted analyses, we found that university hospitals have lower odds than non-teaching hospitals (OR=0.66, 95% CI 0.56 to 0.78) and other teaching hospitals (OR=0.46, 95% CI 0.24 to 0.89), and no significant difference with unspecified teaching status hospitals (OR=0.92, 95% CI 0.80 to 1.05, τ2=0.009). Other teaching hospitals had higher odds than non-teaching hospitals (OR=1.23, 95% CI 1.12 to 1.35). Comparison between unspecified teaching hospitals and non-teaching hospitals (OR=0.91, 95% CI 0.50 to 1.65, τ2=1.007) and unspecified hospitals (OR=0.95, 95% CI 0.76 to 1.20), τ2<0.001) showed no significant difference. While the main analysis in larger sized groups of analysed studies reveals no effect between hospitals, subgroup analyses show that teaching hospitals carry out fewer caesarean sections in several countries, for several study populations and population characteristics.ConclusionsWith smaller sample of participants and studies, in clearly defined hospitals categories under comparison, we see that university hospitals have lower odds for caesarean. With larger sample size and number of studies, as well as less clearly defined categories of hospitals, we see no significant difference in the likelihood of caesarean sections between teaching and non-teaching hospitals. Nevertheless, even in groups with no significant effect, teaching hospitals have a lower or higher likelihood of caesarean sections in several analysed subgroups. Therefore, we recommend a more precise examination of forces sustaining these trends.PROSPERO registration numberCRD42020158437.

Background Unnecessary caesarean births may be affected by physician factors, such as preferences, incentives and convenience. Delivery during office hours can be a valuable proxy for measuring such effects. Objective To determine the effect of office hours on the decision for caesarean delivery by assessing the odds of caesarean during office hours compared to out-of-office hours. Search strategy We searched CINAHL, ClinicalTrials.gov, The Cochrane Library, PubMed, Scopus and Web of Science from the beginning of records through August 2021. Data collection and analysis Search results were screened by three researchers. First, we selected studies that reported odds ratios of caesareans, or data allowing their calculation, for office and out-of-office hours. We extracted data on the study population, study design, data sources, setting, type of caesarean section, statistical analysis, and outcome measures. For groups reporting the same outcome, we performed a standard inverse-variance random-effects meta-analysis, which enabled us to calculate the overall odds ratios for each group. For groups reporting varying outcomes, we performed descriptive analysis. Main results Meta-analysis of weekday vs weekend for any caesarean section showed higher odds of caesarean during weekdays in adjusted analysis 1.40 (95%CI 1.13, 1.72 from 1,952,691 births). A similar effect was observed in the weekday vs Sunday comparison (1.39, 95%CI 1.10, 1.75, 150,932 births). A lower effect was observed for emergency CS, with a slight increase in adjusted analysis (1.06, 95%CI 0.90, 1.26, 2,622,772 births) and a slightly higher increase in unadjusted analysis (1.15, 95%CI 1.03, 1.29, 12,591,485 births). Similar trends were observed in subgroup analyses and descriptive synthesis of studies examining other office hours outcomes. Conclusions Delivery during office hours is associated with higher odds for overall caesarean sections and little to no effect for emergency caesarean. Non-clinical factors associated with office hours may influence the decision to deliver by caesarean section. Further detailed investigation of the “office hours effect” in delivery care is necessary and could lead to improvements in care systems.

Background: Some studies have assessed the seroprevalence of anti-SARS-CoV-2 antibodies in different populations. Very few studies have explored seroprevalence in municipal workers, an important and potentially high-risk population. This study aims to determine the prevalence of anti-SARS-CoV-2 antibodies in municipal workers, with the additional examination of the association of prevalence with various demographic, health-related, and epidemiological factors. Methods: We surveyed and tested for seroprevalence 418 public servants from the municipality of Prishtina, the capital of Kosovo. The primary prespecified outcome was the seroprevalence of anti-SARS-CoV-2 antibodies, IgG, and IgM. Additional outcomes were crude and adjusted odds ratios of seroprevalence by different factors. Results: 21.1% of municipal workers tested positive for either IgM or IgG. Of these, 9.6% were positive for IgM and 19.4% for IgG. Data showed high levels of adherence to protective measures, e.g., social distancing in the office, but calculation of ORs did not show a significant difference between those reporting adherence to such measures and those reporting nonadherence. Of other examined factors, significantly lower odds were observed for smokers (0.52, 95% CI 0.28, 0.97), while municipal workers with infected family members had elevated odds of seropositivity according to both crude (2.19, 95% CI 1.34, 3.59) and adjusted (2.00, 95% CI 1.17, 3.41) ORs. Conclusions: Most answers from public servants demonstrated compliance to social-distancing policies in the workplace, but analysis of crude and adjusted odds ratios did not suggest a significant effect between municipal workers who followed these guidelines and those who did not. Results from this study help Kosovo policy makers in understanding the level of prevalence of COVID-19 in municipal workers and the effect of different factors on such prevalence. Results from the study could inform future decisions on the design and application of protective measures for municipal workers. Our findings should encourage further research to assess the extent of the spread of COVID-19 to other essential workers in Kosovo, including retail workers.
