Background and Purpose: Because of several methodological limitations, previous studies focusing on the prevalence of large vessel occlusion in ischemic stroke (IS) patients provided conflicting results. We evaluated the incidence of IS with a visible arterial occlusion using a comprehensive population-based registry. Methods: Patients with acute IS were prospectively identified among residents of Dijon, France, using a population-based registry (2013–2017). All arterial imaging exams were reviewed to assess arterial occlusion. Annual incidence rates of IS (first-ever and recurrent events) and IS with a visible occlusion were calculated. Results: One thousand sixty cases of IS were recorded (mean age: 76.0±15.8 years, 53.9% women). Information about arterial imaging was available in 971 (91.6%) of them, and only preexisting dementia was independently associated with having missing information (odds ratio=0.34 [95% CI, 0.18–0.65], P =0.001). Among these patients, 284 (29.2%) had a visible arterial occlusion. Occlusion site was the anterior circulation in 226 patients (23.3% of overall patients with available data) and the posterior circulation in 58 patients (6.0%). A proximal occlusion of the anterior circulation was observed in 167 patients (17.2%). The crude annual incidence rate of total IS per 100 000 was 138 (95% CI, 129–146). Corresponding standardized rates were 66 (95% CI, 50–82) to the World Health Organization and 141 (95% CI, 118–164) to the 2013 European populations. The crude annual incidence rate of IS with a visible arterial occlusion per 100 000 was 37 (95% CI, 33–41) and that of IS with a proximal occlusion of the anterior circulation was 22 (95% CI, 18–25). Corresponding standardized rates were 18 (95% CI, 10–26) and 10 (95% CI, 8–13) to the World Health Organization population, and 38 (95% CI, 26–50) and 23 (95% CI, 19–26) to the 2013 European population, respectively. Conclusions: These results will be helpful to plan the need for thrombectomy-capable stroke center resources.

We investigated the prevalence of clinical trachoma in 154,265 children aged 6 to 16 years in 206 Shanghai migrant schools. Clean water availability in school, each child’s facial cleanliness, eyelids, corneas, and the presenting distance visual acuities were examined. Trachoma was clinically diagnosed in accordance with the World Health Organization simplified classification. Eyes diagnosed with trachoma were swabbed to test for ocularChlamydia trachomatisinfections (OCTI) with a rapid latex immunochromatographic test. Among 153,977 students, no blindness was found related to trachoma. Trachoma was diagnosed in 8029 children (5.2%). In 87 schools clinical trachoma prevalence was higher than 5%. OCTI was confirmed in 2073 of 6823 trachoma diagnosed children (30.4%). Clinical trachoma prevalence was higher among females than males (p<0.001), but gender comparison showed no statistical difference in the prevalence of OCTI (p=0.077). Age and clinical trachoma (r=-0.014;p<0.001) or OCTI (r=-0.026;p=0.031) prevalence were negatively correlated. Clinical trachoma was different in different districts and counties (p<0.001). Trachoma warrants close attention in Shanghai migrant children because the condition remains endemic in some schools.

Governments all over the world are currently grappling with the COVID-19 pandemic. While some countries were very hard hit, others were only mildly hit but all are still taking measures to mitigate the consequences. The virus emerged in December 2019 in Wuhan, China and spread to most continents by the beginning of March 2020, which led to the World Health Organization declaring it as a pandemic on the 11th of March 2020. Since it was a novel disease, there was limited information on the virus, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) belongs to the same family as the Severe Acute Respiratory Syndrome Coronavirus 1 (SARS-CoV-1) and the Middle East Respiratory Syndrome Coronavirus (MERS-CoV). Researchers all over the world started working simultaneously to understand the virus to provide the necessary treatment regime or vaccine in order to reduce the impact of the virus on its victims. Africa and other developing countries with limited resources and poor planning and management are expected to be among the worst hit in the long run. The implications of the COVID-19 on food, water, hygiene, sanitation, and the environment in Africa have been reviewed in this paper, as well as possible implications they may pose to the population, based on the existing common practices and their immediate impacts. This information can assist policymakers in Africa to adequately plan the management of the COVID-19 in order to lessen its impact on the population.

Semen analysis is of paramount importance to study potential male fertility, couple's infertility, the effects of gonadotoxic agents on spermatogenesis and as follow-up test during treatment of male infertility. Since 1987, the World Health Organization proposes the standardization of this test and its reference values based on population-based data. The latest version of the World Health Organization guidelines was published in 2010. It introduced a new methodology that produced new references values, which triggered a discussion that lies inconclusive. We revised the original World Health Organization paper focusing on methodological changes and its results, the new references values and their impact on clinical practice.

Overweight and obesity affect a large proportion of the population and are important causes of death in both developed and low- and middle-income countries. In Guinea-Bissau, there are no previous population-based studies assessing this phenomenon. Therefore, we aimed to quantify the prevalence of underweight, overweight, and obesity among adults in Bissau. A stratified and cluster sample of 935 adults was assembled in 2021 and was evaluated using standardized questionnaires and anthropometric measurements, following the World Health Organization Stepwise Approach to Chronic Disease Risk Factor Surveillance. Underweight, obesity, and overweight were defined by body mass index based on the World Health Organization definitions. The prevalence of overweight and obesity was 48.7% among women and 25.0% among men. The proportion of women with abdominal obesity was 14 times higher than it was in men (35.3% vs. 2.5%). The prevalence of overweight and obesity increased with age and income. Underweight was more prevalent in the age group of 18 to 24 years (18.4% in women and 28.9% in men) and was less frequent among individuals with higher socioeconomic status. In conclusion, the prevalence of overweight and obesity is similar to the trends that are observed in many other urbanized populations in Africa and is already a major public health issue in urban Guinea-Bissau.

Abstract BackgroundVisual impairment impacts negatively on quality of life. Kenya has a total fertility rate of 3.5 an indication of more younger generation. However, little is known on the prevalence and causes of visual impairment in the children population of Kenya.MethodsThis cross-sectional population-based study included 3400 (1800, 52.9% female) randomly selected children with a mean age of 12 ± 2 years (range 5–16 years) in Kenya. Visual acuity was taken using snellens chart at 6 meters. Anterior and posterior segments were assessed using slit lamp and indirect ophthalmoscope. The World Health Organization formed the baseline for calculating prevalence of visual impairment.ResultsVisual acuity measurements were available for 3240 (95.3%) participants. The prevalence of visual impairment, based on pin-hole value, using World Health Organization, was 1.7 ± 0.3%. The prevalence of visual impairment, based on presenting visual acuity value, was 2.4 ± 0.7%, using the World Health Organization definition. Multivariate analysis demonstrated that the presence of visual impairment on pin-hole, according to World Health Organization definition increased significantly with increasing age (odds ratio 1.230, P = .021) and increased astigmatism (odds ratio 0.834, P = .032), but not significantly associated with socioeconomic, ocular conditions after adjusting for age and astigmatism. Lack of refractive error correction was the most common reason for presenting visual impairment. Causes of visual impairment due to presenting visual acuity were amblyopia (24%), nystagmus (14%), myopia (49%) and hyperopia (13%).ConclusionThe prevalence of visual impairment in Kenya increased significantly with socio-economic activities. Uncorrected refractive error remains the major causes of visual impairment.

Switzerland adheres to the objective of eliminating measles within the European region of the World Health Organization (WHO) by 2010. After several years with a relatively low annual incidence rate (0.3 to 1 case per 100,000 inhabitants), there has been a large epidemic of measles from November 2006 to August 2009. By mid September 2009, 4,415 cases were notified by physicians and laboratories, corresponding to an incidence rate of 15 per 100,000 in 2007 and 29 per 100,000 in 2008; by far the highest rates in Europe. This exceptionally long nationwide epidemic comprised three successive waves, with peaks in August 2007 (171 cases), March 2008 (569 cases) and March 2009 (417 cases). It mainly affected children aged from five to 14 years (48% of cases). Most cases were not vaccinated (93%) or were incompletely vaccinated (5%). In total 656 patients (15%) suffered complications or were hospitalised. Insufficient, spatially heterogeneous immunisation coverage (87% for at least one dose at the age of two years at the national level) has allowed a sequence of numerous outbreaks to occur, despite the gradual strengthening of measures to control the disease. Several exportations to Europe (81 in 2007 and 2008) and to the rest of the world (10 for the whole of the epidemic) have in some instances caused large outbreaks. The epidemic was a threat to the goal of eliminating measles in Switzerland and in Europe. The Federal Office of Public Health (FOPH) and its partners are currently working on a national strategy to eliminate measles.
