Analysis of injuries in Judo athletes: A systematic review (Análisis de lesiones en deportistas de judo: revisión sistemática)

This article aimed to identify general characteristics, etiology, and location of injuries in Judo athletes. A systematic literature search was carried out up to July 2020 on the databases MEDLINE (via PubMed), LILACS (via BVS), and Science Direct to find studies that focused on the type, location, and causes of injuries in Judo athletes of both sexes and older than 18 years old. The following data were extracted from the studies: author/year, study country, sample size, competition level, injury type, location, and context of the injury. The methodological quality of the included studies was assessed by the Critical Appraisal Skills Programme (CASP) tool. A total of 727 studies were retrieved from the databases and 12 were selected. The selected studies involved athletes from national and international levels. The situation of training and competition was the most cited context of injury. Considering injury etiology, the location was generalized in most of the studies and the more frequent injury types were: sprains, strains, dislocations, and fractures. In relation to severity, head and neck injuries were described in 66% of the studies. Our results suggest higher awareness related to technical learning strategies to Judo practitioners that is independent of skill level. Since injury etiology is a multifaceted process, increased efforts must be invested to lower or avoid more severe injuries that are more prone to produce negative outcomes like death or disabilities. Resumen. El objeto de este estudio consiste en identificar las características generales, etiología y ubicación de las lesiones en los deportistas de Judo. Se llevó a cabo una búsqueda bibliográfica sistemática hasta julio de 2020 en las bases de datos MEDLINE (a través de PubMed), LILACS (a través de BVS) y Science Direct para encontrar estudios que se centraran en el tipo, la ubicación y las causas de las lesiones en los atletas de Judo de ambos sexos y sexos mayores de 18 años. Se extrajeron los siguientes datos de los estudios: autor/año, país del estudio, tamaño de la muestra, nivel de competencia, tipo de lesión, ubicación y contexto de la lesión. La calidad metodológica de los estudios incluidos se evaluó mediante la herramienta Critical Appraisal Skills Program (CASP). Se recuperaron un total de 727 estudios de las bases de datos y se seleccionaron 12. Los estudios seleccionados involucraron a deportistas de nivel nacional e internacional. La situación de entrenamiento y competición fue el contexto de lesión más citado. Teniendo en cuenta la etiología de la lesión, la ubicación fue generalizada en la mayoría de los estudios y los tipos de lesión más frecuentes fueron: esguinces, distensiones, luxaciones y fracturas. En relación con la gravedad, las lesiones de cabeza y cuello se describieron en el 66% de los estudios. Nuestros resultados sugieren una mayor conciencia relacionada con las estrategias de aprendizaje técnico para los practicantes de Judo que es independiente del nivel de habilidad. Dado que la etiología de las lesiones es un proceso multifacético, se deben invertir mayores esfuerzos para reducir o evitar lesiones más graves que son más propensas a producir resultados negativos como muerte o discapacidades.

The epidemiology of attacks on statues: New Zealand as a case study

Objectives We aimed to describe the epidemiology of statue attacks along with statue representativeness relative to modern day demographics in one case study country: New Zealand. Methods We performed Internet searches for the existence of outdoor statues of named individuals and historical attacks in New Zealand (NZ), combined a national survey with field visits to all identified statues to examine for injuries and repairs. Results Of the 123 statues identified, nearly a quarter (n = 28, 23%) had been attacked at least once (total of 45 separate attack events), with the number of attacks increasing from the 1990s. Attacks involved paint/graffiti (14% of all statues at least once), nose removal/damage (7%), decapitation (5%), and total destruction (2%). The risk of attack was relatively higher for statues of royalty (50%), military personnel (33%), explorers (29%), and politicians (25%), compared to other reasons for fame (eg, 0% for sports players). Statue subjects involved in colonialism or direct harm to Māori (Indigenous population), had 6.61 (95%CI: 2.30 to 19.9) greater odds (adjusted odds ratio) of being attacked than other subjects. Most of the statue subjects were of men (87%) and Europeans (93%). Other ethnicities were 6% Māori (comprising 15% of the population) and 1% each for Asian and Pacific peoples, who comprise 12% and 7% of the population respectively. Conclusions This national survey found an association between statue attacks and the role of statue subjects in colonialism or direct harm to the Indigenous population. Furthermore, the demography of the statue subjects may represent historical and current social power relationships—with under-representation of women and non-European ethnic groups.

The objective of the Workshop was to share international experiences of (i) how "post-disaster public agencies" in each case study country were established; (ii) how they prepared reconstruction master plans; (iii) how they effectively implemented their post-disaster reconstruction programs.

75 Geographic Location-Allocation Modeling to Optimize National Burn Care Delivery and Disaster Planning

Introduction The study country has a disproportionally high burn incidence rate compared to other low- and middle-income countries. Preventable death and disability are common due to poor population-level spatial access to organized burn care, including no organized system of ground or aeromedical transport. Currently, severe burns are referred to a single facility nationwide, often with suboptimal stabilization and/or significant care delay. Therefore, we aimed to identify existing candidate hospitals that would optimize population-level access to acute burn care if burn stabilization capabilities were strengthened in each hospital. Methods The 175 general hospitals that referred patients to the single national burn referral center between 2016–2020 were designated as candidate hospitals. Demand points for location-allocation modelling were derived from a 2020 estimated population density grid for the country (total population 30,184,338). Road network and national speed limit data were extracted from publicly available geodata to inform travel distance and time. Six models were developed (Models A-F) using cost-distance and network analyses to identify the 3 vs 5 candidate hospitals that would optimize population-level spatial access if their initial burn stabilization capabilities were strengthened. Three travel time thresholds (≤2, 6, and 12 hours) were used for both sets of models. Results Currently, 6,151,298 people (20.3% of the national population) have access to organized burn care within 2 hours of travel, 11,240,957 (37.2%) within 6 hours and 21,925,928 (72.6%) within 12 hours [Table 1]. If acute burn stabilization capabilities were strengthened, Models A-C of 3 chosen hospitals would increase population-level burn care access to 45.2%, 89.4%, and 99.8% of the national population at ≤2, 6, and 12 travel-hours, respectively. Models D-F demonstrated that 5 chosen hospitals would increase population-level burn care access to 53.4%, 95.0%, and 99.9% of national the population at ≤2, 6, and 12 travel-hours, respectively. Conclusions This exercise demonstrates two sets of models for increasing population-level access to acute burn stabilization in the study country. If acute burn stabilization capabilities were strengthened in the identified hospitals, approximately 90% of the national population would have access to burn care within 6 travel-hours in both the 3 and 5 hospital scenarios. Although the models with 5 strengthened hospitals reduce mean travel time, the percent of population with improved travel time access is only marginally higher. Strategic, organized efforts to increase burn stabilization capabilities might reduce the rates of preventable burn-related death and disability country-wide by reducing delays.

Heterogeneity in the prevalence of high-risk human papillomavirus infection in HIV-negative and HIV-positive men who have sex with men in West Africa

Background Men who have sex with men (MSM) are at high risk of human papillomavirus (HPV) infection. We assessed (i) the prevalence of high-risk HPV (HR-HPV) infection and associated factors, and (ii) the prevalence of vaccine-preventable HPV infections in MSM in Burkina Faso, Côte d’Ivoire, Mali, and Togo. Methods A cross-sectional study was conducted in 2017-2018 among MSM ≥18 years old followed in community-based clinics. HPV infection was investigated in oral and anal samples using the e-BRID system. Factors associated with HR-HPV infection were identified using multivariate logistic regressions. Results Among 631 participants, 425 were HIV-negative and 206 HIV-positive. HR-HPV prevalence ranged from 9.2 to 34.8% in the former, and 33.3 to 71.0% in the latter according to the study country. In multivariate analysis, HIV infection (adjusted odds ratio 3.61, 95% confidence interval 2.48–5.27) and study country (4.73, 2.66–8.43 for Mali; 3.12, 1.68–5.80 for Burkina Faso; 3.51, 1.92–6.42 for Togo) were associated with HR-HPV infection. Other associated factors were low educational level, self-defined homosexual identity and condomless anal sex. The prevalence of infections which can be prevented with bivalent, quadrivalent and nonavalent vaccines was 5.9, 27.1, and 34.6% in HIV-negative participants, and 18.9, 43.7, and 54.9% in HIV-positive participants, respectively. Conclusion HR-HPV prevalence was very heterogeneous between the study countries in both HIV-negative and HIV-positive MSM. Vaccine-preventable HPV infections predominated. Vaccination should be proposed to young MSM to reduce the burden of HPV infection in this vulnerable population and their female partners in West Africa.

Methodologycal problems and approaches to identifying and evaluating typical and rare landscapes of the Republic of Belarus

The analysis of the studying of the problem of identifying and evaluating of typical and rare landscapes was carried out, which showed that quite a lot of knowledge has been accumulated in this area of the identification of such landscapes and the criteria for their assessment. It is established that insufficient attention is paid to the classification and mapping of landscapes, the use of mathematical methods for their assessment. A scientific concept is proposed for the study of typical and rare landscapes, which contains four levels of their study (country, regional, subregional, local), the scale of work corresponding to the level, landscape classification units, criteria and indicators for their allocation are determined. So, at the country level, the criterion for assessing typical landscapes is the degree of representativeness, depending on bioclimatic factors and the large size of the landscape contour, at the regional (provincial) – the contour size of the dominant landscapes of the province and the index of landscape diversity, at the subregional – the intensity of anthropogenic transformation, at the local – characteristic value of attractiveness. The main criteria for assessing rare landscapes at the country level are the small size of the contour and the criteria of uniqueness, at the regional (provincial) indicator of occurrence, at the subregional – naturalness, at local – vulnerability. A geographic information database has been created, a methodology has been developed for identifying typical and rare landscapes and their typology. An assessment of landscape diversity was made and the map showing that typical landscapes are characterised by a high and medium level of diversity, and rare landscapes are characterised by medium and low was created. An assessment of the occurrence of rare landscapes was carried out, which made it possible to distinguish three groups – low, medium, and high occurrence; their list and a map of occurrence were created. It has been determined that unique landscapes, which are part of a group with low occurrence, require special protection. A direct correlation has been established between the level of landscape diversity and occurrence. The proposed criteria for identifying and assessing typical and rare landscapes can be used in organising or transforming nature protected areas, in the design of their passports and conservation obligations.

Grain displacement during backwash of drinking water filters

Backwashing rapid sand filters causes inadvertent displacement of filter media grains from their previous depths. This displacement can affect the hydraulic function of filters by mixing or segregating media grains, and the function of biofilters through displacement of active biomass and coatings from proper depths. This study quantifies grain displacement in a pilot-scale filter using tracer grains of colored sand, glass beads, anthracite and garnet to determine the effect of grain size, density and shape on grain displacement. Statistical moments are used to describe the depth distributions resulting from displacement during backwashing. Results show that significant grain displacement occurs during backwash consisting of air scour, air-and-water wash and sub-fluidization water-only wash. Here, displacement is largely independent of grain size, density and shape. When fluidization backwash is used, greater displacement and more dependence on grain characteristics is seen. A variety of grain movement phenomena can be observed during the backwashing steps, indicating that grain movement and therefore the resulting displacement is highly inhomogeneous in four dimensions. These results have direct practical implications for the design of rapid sand filters and the optimization of backwashing procedures, while suggesting that the current widespread backwashing practice used in the case study country (Denmark) should be abandoned.

Does the Use of Proton Pump Inhibitors Increase the Risk of Pancreatic Cancer? A Systematic Review and Meta-Analysis of Epidemiologic Studies

Background: One of the most frequently used medications for treating gastrointestinal disorders is proton pump inhibitor (PPI), which reportedly has potential adverse effects. Although the relationship between the use of PPIs and the risk of pancreatic cancer has been extensively investigated, the results remain inconsistent. Hence, this meta-analysis aimed to evaluate such relationship. Methods: We searched for literature and subsequently included 10 studies (seven case–control and three cohort studies; 948,782 individuals). The pooled odds ratio (OR) and 95% confidence intervals (CI) for pancreatic cancer were estimated using a random-effects model. We also conducted sensitivity analysis and subgroup analysis. Results: The pooled OR of the meta-analysis was 1.698 (95% CI: 1.200–2.402, p = 0.003), with a substantial heterogeneity (I2 = 98.75%, p < 0.001). Even when studies were excluded one by one, the pooled OR remained statistically significant. According to the stratified subgroup analyses, PPI use, and pancreatic cancer incidence were positively associated, regardless of the study design, quality of study, country, and PPI type. Conclusion: PPI use may be associated with the increased risk of pancreatic cancer. Hence, caution is needed when using PPIs among patients with a high risk of pancreatic cancer.

Where Are You From? An Investigation Into the Intersectionality of Accent Strength and Nationality Status on Perceptions of Nonnative Speakers in Britain

We explore how interpersonal and intergroup perceptions are affected by a nonnative speaker’s accent strength and the status of their home country. When nationality information was absent (Study 1), natives who heard a strong (vs. weak) accent rated the speaker as warmer but immigrants as a group as more threatening. This result was replicated when the speaker’s nationality was familiar (Study 2) but in this study, country status further shaped accent-based perceptions: the strong (vs. weak) accented speaker evoked more positive interpersonal perceptions when her country status was low, but more negative intergroup perceptions when her country status was high. When the status of the speaker’s nationality was manipulated (Study 3), we replicated the interpersonal perceptions found in Study 1 and the intergroup perceptions found in Study 2. Findings support a holistic approach to investigating perceptions of nonnative speakers: one that considers nationality as well as accent strength.

Attacks on statues associated with social injustice and militarism: New Zealand as a case study

We aimed to explore the potential relationship between social injustice and militarism and attacks on statues in one case study country: New Zealand. We performed Internet searches for the existence of the statues and historical attacks in New Zealand (NZ), combined with field visits to all identified statues to examine for injuries and repairs. Of the 123 statues identified, nearly a quarter (n=28, 23%) had been attacked at least once (total of 45 separate attack events), with the number of attacks increasing from the 1990s. Attacks involved paint/graffiti (14% of all statues at least once), nose removal/damage (7%), decapitation (5%), and total destruction (3%). The risk of attack was relatively higher for statues of royalty (50%), military personnel (33%), explorers (29%), and politicians (25%), compared to other reasons for fame (eg, 0% for sports players). Statue subjects involved in colonialism and harm to Māori, had 6.61 (95%CI: 2.30 to 19.9) greater odds (adjusted odds ratio, aOR) of being attacked than other subjects. Similar results were found for statue subjects having any involvement with the military (aOR= 4.17; 95%CI: 1.65 to 11.3). Most of the statue subjects were of men (87%) and Europeans (93%). Other ethnicities were 6% Māori (NZ’s Indigenous population comprising 15% of the population) and 1% each for Asian and Pacific peoples, who comprise 12% and 7% of the population respectively. In conclusion, there is evidence that attacks on these statues may reflect the role of statue subjects in past social injustices and militarism. Furthermore, the demography of the statue subjects in this country represent historical and current social power relationships – with under-representation of women and non-European ethnic groups.
