Background: COVID-19 pandemic, which started in late 2019, has brought various ups and downs worldwide. Planned policies were highly useful in the first wave of the COVID-19 pandemic in Iran. However, due to several reasons, the country faced the second wave. Objectives: The current study aimed to compare patients’ features in the first two waves of the COVID-19 pandemic in the city of Tehran, Iran. Methods: Following a retrospective, cross-sectional design, the current study was carried out on 5000 suspected/confirmed COVID-19 cases who were randomly selected from all cases transferred by ambulance to hospitals located in the city of Tehran. The first wave of the COVID-19 epidemic was from February 20 to May 04, 2020, and the second wave was from May 05 to August 05, 2020. Data for both waves, were collected using a researcher-made checklist. Results: In this study, data of 5000 suspected/confirmed COVID-19 cases were analyzed (2773 cases belonged to the first wave and 2227 to the second one). The mean age of patients (P < 0.001), the frequency of cigarette smoking (P < 0.001), opium abuse (P = 0.004), and the presence of underlying diseases (P < 0.05) were more frequent in the second wave than in the first one. The notable finding in this study was the significant increase of non-respiratory symptoms of patients in the second wave. The number of cases who reported close contact with COVID-19 patients was higher in the second wave. Also, hypoxia, intubation during the hospital stay, length of hospitalization, and mortality rates were significantly lower in the second wave. During the second wave, the odd ratio of positive findings in lung CT-scan was 3.4 (95% confidence interval: 2.51 to 4.55) compared to the first wave (P < 0.001). Conclusions: This study demonstrated considerable differences between the first and second waves of the COVID-19 pandemic concerning the patients’ features.

Background and objective: nowadays, one of the most important risks threatening the community health promotion and development is increasing the number of accidents. The aim of this study was to evaluate the demographic characteristics of people injured by driving accidents and admitted to Imam Khomeini Hospital of Urmia in 2016. Methods: This cross-sectional and retrospective study was conducted using the census method. It was conducted on all road accident patients hospitalized in Imam Khomeini Hospital of Urmia in 2016. A total of 2050 records were reviewed and 2015 of them were included in the study. Data were collected using a checklist in which demographic and accidental data of the injured people were recorded. Data were analyzed using descriptive statistics (frequency distribution tables, central indicators, and dispersion). Results: The mean age of the subjects was 33.63± 18.53 years. Most of the injured people were male (73.2%) and self-employed (46.8%). The majority of females were housewives (70.8%). In two gender groups, most accidents occurred on the streets and within the city. Moreover, 48.1% of injured people were male and 48.1% of females were transferred to the hospital by emergency department and 56 (0.20%) of injured people died before discharge from the hospital. Conclusion: Most accidents occurred on the streets and within the city and among males, low education, and self-employed people. Hence, this group of people should be in priority in designing and implementing a variety of educational interventions.

Introduction: The aim of this study was to estimate the seroprevalence of the SARS-CoV-2 infection in health workers of the Sanitary Region VIII, at province of Buenos Aires during June 2020. Methods: a cross-sectional design was used. A probabilistic sampling by two-stage conglomerates was carried out. Data were collected from a self-administered questionnaire and a blood sample for antibody identification. The COVIDAR IgG and IgM test were used. RESULTS: 738 health workers were included; the overall response rate was 73.80%. 71.83% of that were women; age showed a normal distribution. Nurses and doctors accounted for more than half of the staff. 75.86% of people claimed to always use Personal Protective Equipment. 5.61% of people had close contact with a confirmed case of COVID-19. 4.60% of people had previously had a nasopharyngeal swab with a negative result. Five workers had positive IgG for SARS-CoV-2 (four women and one man) with negative IgM. The mean age of the cases was 35 years old; two of them were asymptomatic; neither of them had a swab sample taken. The overall seroprevalence was 0.75%, with no significant differences between strata. Discussion: the seroprevalence found was low; indicating a large proportion of workers was susceptible to infection. We stress the need to complement passive epidemiological surveillance strategies with serological monitoring in health workers.

OBJECTIVES: The objective of this study was to compare working length calculated with conventional radiographs and an electronic apex locator (IPEX II) during the root canal treatment of mandibular anterior teeth. METHODOLOGY: A cross-sectional study was done in the Department of Operative Dentistry, Sardar Begum Dental Hospital, Peshawar during February and March 2018. A consecutive sampling technique was used for sampling. Only 30 patients fulfilled the inclusion criteria of our study. Detailed medical and dental history was taken. Only patient fulfilling inclusion criteria were enrolled in the study. Data were analyzed using SPSS version 20. RESULTS: The mean age for patients was 45.33±5.16. 33% out of 30 patients (10) were male and 20 were females. The mean working length calculated from radiographs was 22.25±1.29 (min 20.09-max 24.10). The mean working length calculated by the electronic apex locator (IPEX II) was 22.17±1.28 (min 20.00-max 24.07). The mean difference between working length calculated by radiograph and electronic apex locator was -0.084mm, which means the working length determined by radiographs and by electronic apex locator has no difference in mandibular anterior teeth with single canals. CONCLUSION: Both the methods can be used effectively in endodontics for single-rooted mandibular teeth, but if both are used in combinations can lead to an improvement in the working length accuracy, which may significantly reduce the number of radiographs exposure, and increase the success and comfort for endodontic patients.

Objective: To assess factors associated with the average number of dental caries in pregnant women. Method: Basic research design: This cross-sectional study was performed between January 2017 and December 2018 in Santa Maria, Brazil. Clinical setting and participants: Multistage random sampling resulted in the recruitment of 256 pregnant women from public health centers across the city. Clinical exams and semi-structured questionnaires including demographic, socioeconomic and behavioral questions were performed by trained interviewers. Main outcome measure: The experience of dental caries was evaluated through the mean value of the Decay, Missing, and Filled Surface Index (DMFS) by 4 trained and calibrated examiners. Multilevel Poisson regression models were used to evaluate the influence of different variables on the average number of dental caries. Rate ratio (RR) and respective 95% confidence intervals were calculated (CI 95%). Results: The prevalence of untreated dental caries was 62.7% in the sample, while the mean DMFS index was 10.27 (± 10.92). Women who smoked during pregnancy had a higher mean DMFS (RR 1.41; 95% CI 1.25-1.57). Furthermore, pregnant women who had poor self-ratings of oral health had a higher average DMFS (RR 1.21; 95% CI 1.10-1.32). Conclusions: The results showed that older age, ethnicity, fewer years in education and the presence of dental plaque resulted in higher means of DMFS.

AbstractObjective:To assess the Na content and price of bread available in bakeries in the city of Maputo in 2018 and describe trends since 2012.Design:Cross-sectional evaluation of bread sold in twenty bakeries in the city of Maputo. Three loaves of white and three loaves of brown bread were collected from each bakery when available, and Na contents were quantified by flame photometry. To assess trends, samples of white bread collected in 2012 and analysed using the same methodology were compared with samples of white bread collected in 2018 from the same bakeries.Setting:City of Maputo, capital of Mozambique.Results:In 2018, the mean (range) Na content in mg/100 g of white and brown breads were 419·1 (325·4–538·8) and 389·8 (248·0–609·0), respectively. Non-compliance with Na targets in bread according to the South African regulation (<380 mg/100 g) was observed in 70 % of white and 43 % of brown bread samples. A total of twelve bakeries had samples evaluated in both 2012 and 2018; among these, the mean Na content in white bread decreased by just over 10 % – the mean difference (95 % CI) was 46·6 mg/100 g (1·7, 91·5); and there was a significant increase of 3·7–5·4 meticais in the mean price per 100 g of white bread.Conclusions:The Na content of bread available in bakeries in the city of Maputo decreased in recent years despite the absence of a specific regulation in Mozambique.

Risk Of Preeclampsia

Background: Angiogenic and antiangiogenic imbalances play a major role in the pathogenesis of preeclampsia. Increased production of sFlt-1 by the placenta causes free circulating PIGF and VEGF concentrations to lower because it is bound by sFlt-1. Measuring levels of angiogenic and antiangiogenic proteins as biomarkers indicates placental dysfunction and distinguishes preeclampsia from other disorders. This study aims to analyze the levels of angiogenic and antiangiogenic molecules in pregnant women at risk for preeclampsia.Methods: The study with a cross-sectional design was carried out in 11-15 weeks gestational age whom had a risk of preeclampsia with 30 samples in primary health care starting April-August 2018. Blood serum was measured by molecular levels of VEGF, PlGF, sFlt-1, and sFlt-1/PlGF ratio using the ELISA method. Data analysis used Pearson product moment test.Results: The mean of VEGF levels are 15.5±21.6, PlGF 89.7±55.5, sFlt-1 11519.4±5126.0 and the ratio sFlt-1/PlGF 166.7±102.1. Correlation value of risk factors for preeclampsia with molecular levels of VEGF r= -0.05; p = 0.76, PlGF r= -0.21; p = 0.26, sFlt r= 0.01; p =0.99 and ratio sFlt-1/PlGF r = 0.10; p = 0.58.Conclusions: The higher the total score of preeclampsia risk factor, the lower the molecular level of VEGF and PlGF is. Moreover, the higher the total score of preeclampsia risk factor, the higher the molecular level sFlt-1 and the sFlt-1/PlGF ratio is. There are no significant correlation between total score of preeclampsia risk factor and levels of molecule VEGF, PlGF, sFlt-1 and sFlt-1/PlGF ratio.

Abstract: The objective of this study was to identify the food vendor distribution profile of the city of Florianópolis, Santa Catarina State, Brazil, and investigate its association with the socioeconomic and demographic characteristics of different municipal regions. This descriptive, cross-sectional study obtained the location of food vendors from secondary data from different institutional sources. The density of different types of food vendors per 1,000 inhabitants in each municipal weighted area was calculated. The Kruskal-Wallis test compared the mean density of food vendors and the weighted income areas. The lowest-income regions had the lowest density of butchers, snack bars, supermarkets, bakeries/pastry shops, natural product stores, juice bars, and convenience stores. The identification of these areas may encourage the creation of public policies that facilitate healthy food startups and/or maintenance of healthy food vendors, especially in the lowest-income regions.
