We present an analysis of short-term associations between ambient NO2 and mortality according to cause, age-group, and period (cold and warm) in 18 areas in metropolitan France for the 2010–2014 period. Associations were estimated in each area using a generalized additive Poisson regression model, and effects were summarized in a meta-analysis. The percentage increase in mortality rate was estimated for a 10 µg m−3 increase in the NO2 level in each area for each complete calendar year and for cold (November to April) and warm periods (May to October) in each year. We found that the NO2 increase (lag of 0–1 days) was associated with a 0.75% increase of non-accidental mortality for all age-groups (95% confidence interval (CI): (0.4; 1.10)). During the warm period, this NO2 increase was associated with a 3.07% increase in non-accidental mortality in the ≥75 years old group (95% CI: 1.97; 4.18). This study supports the short-term effects of NO2 as a proxy of urban traffic pollution on mortality, even for concentrations below the maximum guideline of 40 µg m−3 set down by the European Air Quality Standards and the World Health Organization (WHO).

Melancholy is major mental challenges that is characterize by sadness, sleep disorder, decrease energy, etc. It also have a great social and mental consequences, it is well know that depression will be the second largest cause of disability globally till 2020. The risk are even higher in developed countries. According to world health organization globally it effect more than 121 million people. Depression is a complex and multi-dimensional anarchy according to it has many faces and cannot be describing by one simple formula because it originate from numerous complex mechanism. Multi-faced nature of depression makes it difficult to find out its etiology. The purpose of this study is to find out the prevalence of melancholy in different age groups and genders in district Swat. Overall 300 samples were collected randomly across different age groups and genders in which we found the prevalence of melancholy were 48.3% in which male depressed individual were 27.6% while female depressed were 20.6%. The number of depressed individual were maximum in age group vary from 10-20 which is 15%. To conclude depression is easily manageable but it need understanding that how to control your feeling and thought and think new and positively.

Abstract Background According to the World Health Organization (WHO), the outbreak of coronavirus disease in 2019 (COVID-19) has been declared as a pandemic and public health emergency that infected more than 5 million people worldwide at the time of writing this protocol. Strong evidence for the outcome of COVID-19 among the geriatric age group has not been published in Africa. Therefore, this protocol will be served as a guideline to conduct a systematic review and meta-analysis of the outcome of COVID-19 among the geriatric age group in Africa. Methods Published and unpublished studies on the outcome of COVID-19 among the geriatric age group in Africa and written in any language will be included. Databases (PubMed / MEDLINE, Google Scholar, Google, EMBASE, Web of Science, Microsoft Academic, WHO COVID-19 database, Cochran Library, Africa Wide Knowledge, and Africa Index Medicus) from March to August 2020 will be searched. Two independent reviewers will select, screen, extract data, and assess the risk of bias. The proportion will be measured using a random-effects model. Subgroup analysis will be conducted to manage heterogeneity. The presence of publication bias will be assessed using Egger’s test and visual inspection of the funnel plots. This systematic and meta-analysis review protocol will be reported per the PRISMA-P guidelines. Conclusion This systematic review and meta-analysis protocol will be expected to quantify the outcome of COVID-19 among the geriatric age group in Africa. Systematic review registration This protocol was submitted for registration with the International Prospective Register of Systematic Reviews (PROSPERO) in April 2020 and accepted with the registration number: (https://www.crd.york.ac.uk/PROSPERO).

Objective. To analyze the dynamics of prevalence and severity of dental caries among 12- and 15-year-old schoolchildren in six regions of Lithuania. Material and methods. A total of 5910 schoolchildren aged 12 and 15 years were examined. Dental caries was diagnosed according to the criteria of World Health Organization. The prevalence of dental caries was calculated by dividing the number of children with caries by the number of all children examined and expressed as percentage. Severity of dental caries was described by DMF-T index. DMF-T indices of individual persons as well as each age group were determined. Oral hygiene was evaluated by a simplified oral hygiene index. Fluoride concentration in Kretinga was 1.6–2.2 ppm; in the other regions, it varied between 0.2 to 0.4 ppm. Results. The prevalence of dental caries among 12-year-olds was 88.4% in 1983 and 85.5% in 2005; among 15-year-olds, it was 95.5% and 92.9%, respectively. Mean DMF-T score decreased from 4.5 (in 1983) to 3.7 (in 2005) among 12-year-olds and from 6.4 (in 1983) to 5.6 (in 2005) among 15-year-olds. Oral hygiene index decreased from 1.69 in 1983 to 1.34 in 2005 among 12-year-olds and from 1.46 to 1.22 among 15-year-olds, respectively. Conclusions. A tendency towards decrease in the prevalence and severity of dental caries was observed, when caries prevention program was running. Correlation between oral hygiene and DMF-T was observed in both age groups. Decreased prevalence and intensity of dental caries among 12- and 15-year-olds were associated with improved oral hygiene, usage of fluoride toothpaste, and fluoride content in drinking water.

Background: Anemia is the most commonly observed hematological diseases in children. The World Health Organization (WHO) has estimated that globally, 1.62 billion people are anemic, with the highest prevalence of anemia (47.4%) among preschool-aged children. Of these 293 million children, 89 million live in India. Aim: This study aims to evaluate the factors causing anemia in children aged between 6 months and 5 years and its prevalence within this age group. Methods: This study is a prospective observational study conducted in KIMS Hospital, Bengaluru, Karnataka. A total of 200 children in the age group of 6 months–5 years with features of anemia or having hemoglobin <11 g/dl were included in the study for a duration of 18 months between January 2019 and June 2020. Detailed history was recorded and examination findings were noted. The data collected were tabulated and statistically analyzed accordingly. Results: About 57.5% of the children with anemia fell between the age group of 6 months and 2 years and 42.5% of children were in the age groups of 2–5 years. A male predominance was seen (61%) with male-to-female ratio of approximately 1.56:1. Most of the children were found to have mild (46%) and moderate anemia (46%) with only a minority (8%) presenting with severe anemia. About 56.5% of the children had a normal nutritional status while 41% were malnourished and 2.5% had both wasting and stunting. Exclusive breastfeeding (for 6 months) history was present in 59% of the children. These children belonged mostly to the upper lower (45%) and lower middle (41%) socioeconomic status. This study also showed anemia in children most commonly presented majorly with concurrent involvement of the respiratory system (31%) followed by infectious diseases (30%) and gastrointestinal disorders (23%). Conclusion: The current study concludes that iron deficiency anemia is a multifactorial hematological disease. Learning about the predisposing risk factors can help to adopt the necessary precautions to prevent anemia in these children. Improving the nutritional status of the children by involving parents and counseling them regarding important feeding practices can help to prevent anemia.

Introduction: Dental caries is one of the most common conditions affecting the general health of children. The present study was carried out among school children of Kathmandu valley to determine the prevalence of dental caries in two age groups. Methods: The study was conducted from December 2007 to May 2008. The age of the school children of the study was divided into two group: 5 - 6 years and 12 - 13 years. A stratifi ed cluster sampling with proportional allocation was used while grouping the subjects. The dental status examination was done with the help of trained dentists. Decayed, missed and fi lled teeth index and decayed, missed and fi lled surfaces index (dmft for primary dentition and DMFT for permanent dentition) were used as the standard tools for the determination of prevalence. Results: A total of 638 students (325 of age group 12 - 13 years and 313 of age group 5 - 6 years) from 30 different schools of the Kathmandu valley were included in the study. The caries status was found higher in the age group of 5 - 6 years than in the 12 - 13 years and it was found to be statistically signifi cant (p < 0.001). The dmfs and caries percentage of the age group 5 - 6 years and the DMFS and caries percent of the 12 - 13 years was found to be 3.79, 69 % and 1.6, 53.23 % respectively. The dmft/dmfs value was found to be signifi cant according to the districts in the 5 - 6 years age group whereas the DMFS was found statistically signifi cant among the sexes of the 12 - 13 years age group. Conclusions: The caries percentage was found to be above the recommended level of the World Health Organization. However, the DMFS and DMFT values were within the WHO level. Keywords: Children, dental caries, DMF index.

are important, and used to be well known, human and animal pathogens.A novel coronavirus was identified at the end of 2019, as the cause of a number of pneumonia cases in city in the Hubei Province of China, Wuhan. Appeared to be a highly contagious anthroponotic infection. It rapidly caused an epidemic throughout China, hereafter an increasing number of cases in other countries throughout the world. All age groups, including children, are susceptible to the virus, but this age group is more likely to be asymptomatic. However, children may play a great epidemiological role in the spread of the virus with the absence of clinical signs of respiratory disease. Elderly people are the most severe carriers of the virus, as well as people with concomitant diseases. In February 2020, the World Health Organization (WHO) designated the disease COVID-19, which stands for coronavirus disease 2019 [4]. The virus that causes COVID-19 is designated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2); before, it was referred to as 2019-nCoV. We conducted meta-analysis of currently available data to summarize knowledge about the current epidemic in Russia, the dynamic of spread of the infection and management of the disease. Quarantine measures, which were carried out rather quickly, avoided the rapid spread of infection and thus contributed to a gradual increase in the load on medical facilities. As a result, most hospitals had time to prepare for an increased number of patients with coronavirus infection.

ABSTRACT Objective: To evaluate the prevalence of breastfeeding (BF) and the association between occurrence/duration of BF and overweight/obesity in schoolchildren aged 7-14 years. Methods: This is a cross-sectional study, conducted in 2012-2013, on schoolchildren aged 7-14 years from Florianópolis, Santa Catarina, Southern Brazil. Weight and height were measured according to procedures of the World Health Organization. Breastfeeding and sociodemographic data were obtained from a questionnaire responded by parents/guardians. BF was categorized as a dichotomous variable (yes/no) and according to duration (months). Nutritional status was evaluated according to the Z score of the body mass index per age for sex and it was categorized into two groups: normal weight (<Z score+1) and overweight/obesity (≥Z score+1). The adjusted analysis was performed by logistic regression in two age strata (age groups of 7-10 and 11-14 years). Results: 6.6% of schoolchildren had never breastfed; 16.8% had been breastfed for ≤3 months; 16.7%, for 4-6 months; and 59.9%, for ≥7 months. No statistically significant differences were found in the occurrence and duration of BF between the age groups. The prevalence of overweight/obesity was 34.2%. For age groups (7-10 and 11-14 years), the prevalence of overweight/obesity was 36.7% and 29.8%, respectively. Chance of overweight/obesity for the age group of 7-10 years was lower among schoolchildren who were breastfed (OR=0.54; 95%CI 0.33-0.88), when compared with those who never breastfed. When categorized, the chance of overweight/obesity in the age group of 7-10 years was lower for duration of BF ≤3 months (OR=0.41; 95%CI 0.20-0.83), and 4-6 months (OR=0.48; 95%CI 0.28-0.82) when compared with children who never breastfed. Conclusions: BF for at least six months was associated with a lower chance of overweight/obesity for schoolchildren aged 7-10 years. No association was found for schoolchildren aged 11-14 years.

Introduction: Severe COVID-19 is infrequent in children, with a lethality rate of about 0.08%. This study aims to explore differences in the pediatric mortality rate between countries. Methods: Countries with populations over 5 million that report COVID-19 deaths disaggregated data by quinquennial or decennial age groups were analyzed. Data were extracted from COVID-19 Cases and Deaths by Age Database, national ministries of health, and the World Health Organization. Results: 23 countries were included in the analysis. Pediatric mortality varied from 0 to 12.1 deaths per million people of the corresponding age group, with the highest rate in Peru. In most countries, deaths were more frequent in the 0-4 years old age group, except for Brazil. The pediatric/ general COVID-19 mortality showed a great variation between countries and ranged from 0 (Republic of Korea) to 10.4% (India). Pediatric and Pediatric/general COVID mortality have a strong correlation with 2018 neonatal mortality (r=0.77, p<0.001 and r= 0.88, p<0.001 respectively), while it has a moderate or absent (r=0.47, p=0.02 and r=0.19, p=0.38, respectively) correlation with COVID-19 mortality in the general population. Conclusions: There is an important heterogenicity in pediatric COVI-19 mortality between countries that parallels historical neonatal mortality. Neonatal mortality is a known index of the quality of a country s Health System which points to the importance of social determinants of health in pediatric COVID-19 mortality disparities, an issue which should be further explored.

Background/Aim. World Health Organization (WHO) in its plan for health policy until the year 2010, has taken reduction of risk factors of suicide as its 12th aim. Because of the fact that the problem of suicide is also significant health problem in our society, the aim of this study was to examine the influence of life period as a risk factor for suicide in the area of the town of Kragujevac. Methods. In total 211 persons, both sexes, aged between 17 and 91 years, from the area of the town of Kragujevac, who had been committed a suicide during the period from 1996 to 2005, were included in a retrospective study. This study included the analysis of: conditions prior to suicide, locations of suicide, motives for suicide, the ways of committing suicide. For statistical analysis ?2 test and univariante regression model were used. Results. Average rate of suicide, in analyzed period, moved from 8.7 to 27 with a mean value of 14.6? 6.9. Suicide rates were the lowest in the age group from 15 to 24 years and the highest in the age group above 65 years (p < 0.05). Among the presuicidal conditions, within any age groups the presence of mental disease dominated as a factor for suicide, but within the oldest one in which organic diseases prevailed as a factor for suicide (p < 0.05). Statistically significant fact is that a house (flat) was the main location for committing suicide in any age groups. Motives for suicide were significantly different within the groups and they were mostly unknown. Committing suicide by hanging was the most frequent way of suicide among any age groups. Univariant regression analysis failed to show any impact of age on the analyzed factors. Conclusion. Because of the fact that an average rate of suicide in elderly increases it is obligatory to primarily determine risk factors for suicide among people more than 65 years of age. Physicians should play the most important role in that.

Abstract The World Health Organization currently recommends assessing elimination of onchocerciasis by testing whether Ov16 antibody prevalence in children aged 0–9 years is below 0.1%. However, the certainty of evidence for this recommendation is considered to be low. We used the established ONCHOSIM model to investigate the predictive value of different Ov16-antibody prevalence thresholds in various age groups for elimination of onchocerciasis in a variety of endemic settings and for various mass drug administration scenarios. According to our simulations, the predictive value of Ov16 antibody prevalence for elimination depends highly on the precontrol epidemiologic situation, history of mass drug administration, the age group that is sampled, and the chosen Ov16-antibody prevalence threshold. The Ov16 antibody prevalence in children aged 5–14 years performs best in predicting elimination. Appropriate threshold values for this age group start at 2.0% for very highly endemic areas; for lower-endemic areas, even higher threshold values are safe to use. Guidelines can be improved by sampling school-aged children, which also is operationally more feasible than targeting children under age 10 years. The use of higher threshold values allows sampling of substantially fewer children. Further improvement can be achieved by taking a differentiated sampling approach based on precontrol endemicity.
