Influence of the size of the cities of birth and residence in the sports career: an analysis through the bolsa-atleta program / Influência do tamanho das cidades de nascimento e residência na carreira desportiva: uma análise por meio do programa bolsa-atleta

ABSTRACT This study aimed to verify whether the size of municipalities in which Brazilian high-performance athletes are born or live influences the federal government subsidy, in addition to pointing out whether factors such as human development index, demographic density and municipal investment in sports also exert influence. The sample consisted of 2,033 Brazilian municipalities that had athletes, born or resident, receiving the Brazilian incentive Bolsa-Atleta program. The size of municipalities influences the amount and level of grant obtained, demonstrating that the smaller the population size, the lower the chance of obtaining a higher grant level. In addition, factors such as human development index, demographic density and investment in sport influence the acquisition of grants by athletes, mainly by resident athletes, which shows an internal sports migration in the country as a result.

RESUMO O presente estudo teve por objetivo verificar se o tamanho dos municípios em que os atletas brasileiros de rendimento nascem ou residem gera influência na obtenção de subsídio pelo governo federal, além de apontar se fatores como índices de desenvolvimento humano, densidade demográfica e investimento municipal no esporte também exercem influência. A amostra consistiu em 2033 municípios brasileiros que apresentaram atletas nascidos ou residentes contemplados pelo programa de incentivo brasileiro Bolsa-Atleta. Por meio da análise, pode-se verificar que o tamanho dos municípios influência na quantidade e no nível de bolsa obtido, demonstrando que quanto menor o tamanho da população, menor a chance de se obter um nível mais alto de bolsa. Além disto, pode-se notar que fatores como índices de desenvolvimento humano, densidade demográfica e investimento no esporte exercem influência na aquisição de bolsas pelos atletas, principalmente, por parte de atletas residentes, o que evidencia uma migração esportiva interna no país.

Identificación de las zonas con dificultades geográficas de acceso a los servicios públicos de salud en Costa Rica: una propuesta metodológica / Identification of areas with geographical access difficulties to public health services in Costa Rica: a methodological proposal

Objetivo: el propósito de este estudio es presentar y aplicar una herramienta metodológica para identificar las zonas en las cuales el acceso a los servicios de salud pudiera resultar difícil para la población debido a la barrera geográfica, tanto por su distancia al centro médico, como por su capacidad de desplazamiento, específicamente en los cantones de Curridabat, Escazú y Desamparados. Métodos: a partir de la división geográfica del país en unidades geoestadísticas mínimas realizada por el Instituto Nacional de Estadísticas y Censos, se calculó, por cada unidad, la distancia en minutos que se tardaría en recorrer caminando, por la ruta real más rápida, desde la unidad geoestadística mínima hasta la sede de su equipo básico de atención en salud asignado. Resultados: el 3,4% de la población estudiada vivía en una unidad geoestadística mínima clasificada como con dificultad importante de acceso a los servicios de salud, pues presentaba tanto la barrera física de la distancia, como poco desplazamiento en automotores y baja condición socioeconómica. Se identificaron 65 unidades geoestadísticas mínimas (sobre 2014 incluidas en el estudio) que se encontraban a más de 20 minutos caminando de la sede de su equipo básico de atención en salud y cuya población contaba con baja capacidad de desplazamiento y baja condición socioeconómica; la mayoría de ellas en el Área de Salud de Desamparados. Conclusión: este estudio presenta una herramienta metodológica para aplicar en la identificación de zonas a cuya población le pudiera resultar difícil el acceso geográfico a los servicios de salud, tanto por su distancia a un centro médico, como por su capacidad de desplazamiento, específicamente en los cantones de Curridabat, Escazú y Desamparados.

Aim: The objective of this study is to present and apply a methodological tool to identify the areas in which the inhabitants could have geographic access difficulties as a barrier to access to health services, both because of its distance from the health center and its mobility capacity, specifically in the cantons of Curridabat, Escazú and Desamparados. Methods: Based on the geographical division of the country into minimum geostatistical units carried out by the Instituto Nacional de Estadísticas y Censos, the distance in minutes that it would take to walk it was calculated for each unit, based on the actual fastest route between the minimum geostatistical unit and the headquarters of its assigned basic health care team. Results: An 3.4% of the studied population lived in a minimum geostatistical unit classified as having significant difficulty accessing health services since they accumulated both the physical barrier of distance and little mobility in automobiles. 65 minimum geostatistical units were identified (out of 2014 included in the study) as being at more than 20 minutes walking from the basic health care team, with a population with low mobility capacity, and consequently low socioeconomic status. Most of these were found in the Desamparados Health Area. Conclusion: This study presents and applies a methodological tool to identify the areas in which the inhabitants could have geographic access difficulties as a barrier to access to health services, both due to their distance from the health center and their mobility capacity, in Curridabat, Escazú and Desamparados.

Mortality inequalities measured by socioeconomic indicators in Brazil: a scoping review

ABSTRACT OBJECTIVE Summarize the literature on the relationship between composite socioeconomic indicators and mortality in different geographical areas of Brazil. METHODS This scoping review included articles published between January 1, 2000, and August 31, 2020, retrieved by means of a bibliographic search carried out in the Medline, Scopus, Web of Science, and Lilacs databases. Studies reporting on the association between composite socioeconomic indicators and all-cause, or specific cause of death in any age group in different geographical areas were selected. The review summarized the measures constructed, their associations with the outcomes, and potential study limitations. RESULTS Of the 77 full texts that met the inclusion criteria, the study reviewed 24. The area level of composite socioeconomic indicators analyzed comprised municipalities (n = 6), districts (n = 5), census tracts (n = 4), state (n = 2), country (n = 2), and other areas (n = 5). Six studies used composite socioeconomic indicators such as the Human Development Index, Gross Domestic Product, and the Gini Index; the remaining 18 papers created their own socioeconomic measures based on sociodemographic and health indicators. Socioeconomic status was inversely associated with higher rates of all-cause mortality, external cause mortality, suicide, homicide, fetal and infant mortality, respiratory and circulatory diseases, stroke, infectious and parasitic diseases, malnutrition, gastroenteritis, and oropharyngeal cancer. Higher mortality rates due to colorectal cancer, leukemia, a general group of neoplasms, traffic accident, and suicide, in turn, were observed in less deprived areas and/or those with more significant socioeconomic development. Underreporting of death and differences in mortality coverage in Brazilian areas were cited as the main limitation. CONCLUSIONS Studies analyzed mortality inequalities in different geographical areas by means of composite socioeconomic indicators, showing that the association directions vary according to the mortality outcome. But studies on all-cause mortality and at the census tract level remain scarce. The results may guide the development of new composite socioeconomic indicators for use in mortality inequality analysis.

Proteomics, toxicity and antivenom neutralization of Sri Lankan and Indian Russell's viper (Daboia russelii) venoms

The western Russell's viper (Daboia russelii) is widely distributed in South Asia, and geographical venom variation is anticipated among distant populations. Antivenoms used for Russell's viper envenomation are, however, raised typically against snakes from Southern India. The present study investigated and compared the venom proteomes of D. russelii from Sri Lanka (DrSL) and India (DrI), the immunorecognition of Indian VINS Polyvalent Antivenom (VPAV) and its efficacy in neutralizing the venom toxicity. Methods: The venoms of DrSL and DrI were decomplexed with C18 high-performance liquid chromatography and SDS-polyacrylamide gel electrophoresis under reducing conditions. The proteins fractionated were identified through nano-ESI-liquid chromatography-tandem mass spectrometry (LCMS/MS). The immunological studies were conducted with enzyme-linked immunosorbent assay. The neutralization of the venom procoagulant effect was evaluated in citrated human plasma. The neutralization of the venom lethality was assessed in vivo in mice adopting the WHO protocol. Results: DrSL and DrI venom proteomes showed comparable major protein families, with phospholipases A2 (PLA2) being the most abundant (> 60% of total venom proteins) and diverse (six protein forms identified). Both venoms were highly procoagulant and lethal (intravenous median lethal dose in mice, LD50 = 0.24 and 0.32 µg/g, for DrSL and DrI, respectively), while lacking hemorrhagic and anticoagulant activities. VPAV was immunoreactive toward DrSL and DrI venoms, indicating conserved protein antigenicity in the venoms. The high molecular weight venom proteins were, however, more effectively immunorecognized than small ones. VPAV was able to neutralize the coagulopathic and lethal effects of the venoms moderately. Conclusion: Considering that a large amount of venom can be injected by Russell's viper during envenomation, the potency of antivenom can be further improved for optimal neutralization and effective treatment. Region-specific venoms and key toxins may be incorporated into the immunization procedure during antivenom production.(AU)

Geographic variation of individual venom profile of Crotalus durissus snakes

South American rattlesnakes are represented in Brazil by a single species, Crotalus durissus, which has public health importance due to the severity of its envenomation and to its wide geographical distribution. The species is subdivided into several subspecies, but the current classification is controversial. In Brazil, the venoms of C. d. terrificus and C. d. collilineatus are used for hyperimmunization of horses for antivenom production, even though the distinction of these two subspecies are mostly by their geographical distribution. In this context, we described a comparative compositional and functional characterization of individual C. d. collilineatus and C. d. terrificus venoms from three Brazilian states. Methods: We compared the compositional patterns of C. d. terrificus and C. d. collilineatus individual venoms by 1-DE and RP-HPLC. For functional analyzes, the enzymatic activities of PLA2, LAAO, and coagulant activity were evaluated. Finally, the immunorecognition of venom toxins by the crotalic antivenom produced at Butantan Institute was evaluated using Western blotting. Results: The protein profile of individual venoms from C. d. collilineatus and C. d. terrificus showed a comparable overall composition, despite some intraspecific variation, especially regarding crotamine and LAAO. Interestingly, HPLC analysis showed a geographic pattern concerning PLA2. In addition, a remarkable intraspecific variation was also observed in PLA2, LAAO and coagulant activities. The immunorecognition pattern of individual venoms from C. d. collilineatus and C. d. terrificus by crotalic antivenom produced at Butantan Institute was similar. Conclusions: The results highlighted the individual variability among the venoms of C. durissus ssp. specimens. Importantly, our data point to a geographical variation of C. durissus ssp. venom profile, regardless of the subspecies, as evidenced by PLA2 isoforms complexity, which may explain the increase in venom neurotoxicity from Northeastern through Southern Brazil reported for the species.(AU)

Orthomene (Menispermaceae) in the Brazilian Amazon / Orthomene (Menispermaceae) na Amazônia brasileira

Orthomene comprises four species distributed from Central to South America, of which three occur in phytogeographic domains of Brazil. In Brazil, Amazonia is the main center of diversity for the genus. This work is a taxonomic treatment of Orthomene in Brazil and involved analyzing field collections (between January 2017 and July 2018), types and botanical specimens from 32 national and foreign herbaria. The three species in the study area are Orthomene hirsuta,Orthomene prancei and Orthomene schomburgkii. The latter is the most common and widely distributed species of the genus in the country. An identification key, descriptions, illustrations, distribution data, and additional comments for each species are provided. (AU)

Streptococcus agalactiae - Distribuição sorotípica e relação com fatores de virulência e resistência antimicrobiana / Streptococcus agalactiae - Serotype distriburion and correlation with virulence factors and antibiotic resistance

Streptococcus agalactiae, ou Estreptococo do Grupo B, é um microrganismo que encontrado na microbiota intestinal, vaginal e/ou geniturinária de 10-30% de mulheres saudáveis. A principal infecção causada por S. agalactiae é a sepse neonatal. O bebê pode adquirir o microrganismo durante o parto ao passar pelo canal vaginal, ou até mesmo durante a gestação, caso haja ascensão de S. agalactiae para o útero. Existem diversos fatores associados à infecção do feto por S. agalactiae quando a mãe é colonizada, tais como fator CAMP, cápsula de polissacarídeos, hialuronidase, ß-citolisina/hemolisina e pili. Não existe consenso ou recomendação técnica sobre o tema no Brasil. Segundo o Caderno de Atenção Básica ao Pré-Natal, não existem estudos que levem à recomendação da antibioticoterapia intraparto. É necessário elucidar as características genotípicas de cepas de S. agalactiae isoladas no Brasil para alinhar as práticas clínicas às características fenotípicas do microrganismo. Desta forma, os objetivos deste projeto são: i) classificar cepas de S. agalactiae isoladas de gestantes e não gestantes quanto ao sorotipo capsular, por PCR Multiplex, ii) avaliar a presença e distribuição de fatores de virulência, por PCR e iii) avaliar o perfil de resistência antimicrobiana, pelo método de disco difusão e teste D. Os achados de virulência e resistência a antimicrobianos foram comparados com os sorotipos, gestação, localização geográfica e sítio de isolamento. Foram analisadas 292 cepas isoladas de gestantes e não gestantes em São Paulo, São José dos Campos e Rio de Janeiro. O sorotipo Ia foi o mais prevalente entre as cepas. Na cidade de São José dos Campos não houve diferença significativa entre a prevalência dos sorotipos Ia e V, sendo que o sorotipo V foi mais abundante do que nas cidades de São Paulo e Rio de Janeiro. O sorotipo II foi mais abundante em mulheres não gestantes do que gestantes. Não foram encontradas cepas resistentes à Penicilina e vancomicina; contudo a resistência a Cefepima, Eritromicina e Clindamicina ficou em torno de 22%. Foram encontradas diferenças entre os sorotipos quanto à resistência, genes de virulência e sítio de isolamento das cepas. Portanto essas diferenças podem se refletir no perfil epidemiológico da infecção por S. agalactiae quanto à localização geográfica também quanto à gestação. A incidência de sepse causada por S. agalactiae diminuiu muito nas últimas décadas, contudo o monitoramento constante é necessário para alinhar as práticas clínicas às características fenotípicas do microrganismo

Streptococcus agalactiae, or Group B Streptococcus, is a microorganism found in intestinal, vaginal and/or genitourinary microbiota from about 10-30% of all healthy women. The main infection caused by S. agalactiae is neonatal sepsis. The baby can contract the infection during labor when passing through the vaginal canal, or even during pregnancy, if S. agalactiae ascends from the vaginal canal to the uterus. There are several factors associated to the infection of the fetus by S. agalactiae when the mother is colonized, such as the CAMP factor, polysaccharide capsule, hyaluronidase, ß-cytolysin/hemolysin and pili. There is no consensus or technical recommendation regarding this theme in Brazil. According to the Brazilian guidelines to prenatal care, there is no research that justifies the implementation of intrapartum antibiotic therapy. There is a need to clarify genotype characteristics of S. agalactiae strains isolated in Brazil in order to align clinical practices to phenotypical characteristics of this microorganism. This way, the goals of this project are: i) to classify S. agalactiae strains isolated from pregnant and nonpregnant women according to their capsular serotype, using PCR Multiplex, ii) to evaluate the presence and distribution of virulence factors, using PCR and iii) to evaluate their antibiotic resistance profile, using disk-diffusion and D-zone tests. The findings regarding virulence and resistance were compared to serotypes, pregnancy, geographic localization and the site where the sample was isolated. A total of 292 strains from pregnant and nonpregnant women from the cities of São Paulo, São José dos Campos and Rio de Janeiro were analyzed. Serotype Ia was the most prevalent among the strains. In São José dos Campos there was no significate difference in the prevalence of serotypes Ia and V. Serotype V was the most abundant in São Paulo and Rio de Janeiro. Serotype II was most prevalent in nonpregnant women when compared to pregnant women. No resistance to Penicillin nor Vancomycin was found. However, resistance to Cefepime, Erythromycin or Clindamycin was found in around 22% of strains. There were differences among serotypes regarding resistance, virulence genes and site where the strain was isolated. Therefore these differences can reflect into the epidemiologic profile of S. agalactiae infection in regards to geographic localization and pregnancy. The incidence of sepsis caused by S. agalactiae has decrease in the last few decades, however constant monitoring is necessary in order to align clinical practice to the microorganisms phenotypical characteristics

Diagnostic Test Accuracy Review of Cytology for Squamous Intraepithelial Lesion and Squamous Cell Carcinoma of Uterine Cervix

BACKGROUND: Even though cervico-vaginal smears have been used as a primary screening test for cervical carcinoma, the diagnostic accuracy has been controversial. The present study aimed to evaluate the diagnostic accuracy of cytology for squamous intraepithelial lesion (SIL) and squamous cell carcinoma (SqCC) of the uterine cervix through a diagnostic test accuracy (DTA) review. METHODS: A DTA review was performed using 38 eligible studies that showed concordance between cytology and histology. In the DTA review, sensitivity, specificity, diagnostic odds ratio (OR), and the area under the curve (AUC) on the summary receiver operating characteristic (SROC) curve were calculated. RESULTS: In the comparison between abnormal cytology and histology, the pooled sensitivity and specificity were 93.9% (95% confidence interval [CI], 93.7%–94.1%) and 77.6% (95% CI, 77.4–77.8%), respectively. The diagnostic OR and AUC on the SROC curve were 8.90 (95% CI, 5.57–14.23) and 0.8148, respectively. High-grade squamous intraepithelial lesion (HSIL) cytology had a higher sensitivity (97.6%; 95% CI, 94.7%–97.8%) for predicting HSIL or worse histology. In the comparison between SqCC identified on cytology and on histological analysis, the pooled sensitivity and specificity, diagnostic OR, and AUC were 92.7% (95% CI, 87.3%–96.3%), 87.5% (95% CI, 87.2%–87.8%), 865.81 (95% CI, 68.61–10,925.12), and 0.9855, respectively. Geographic locations with well-organized screening programs had higher sensitivity than areas with insufficient screening programs. CONCLUSION: These results indicate that cytology had a higher sensitivity and specificity for detecting SIL and SqCC of the uterine cervix during primary screening.

Trends of clinical trials from 2014 to 2016 in South Korea

Mandatory registration of clinical trials in public registry can ensure the transparency of clinical trials. Public clinical trial registry of can provide current chronological and geographical distribution of clinical trial throughout the country. We used public clinical trial registry provided by Ministry of Food and Drug Safety to analyze current status of clinical trial from 2014 to 2016 in South Korea. The number of clinical trials in antineoplastic and immunomodulating agents area was the greatest, followed by cardiovascular system and antiinfectives for systemic use as a whole. From 2014 to 2016, overall number of clinical trials decreased while the number of phase I clinical trials increased. Seoul accounted for more than half number of clinical trials in Korea. Supports for clinical trials in non-metropolitan area needs to be considered.

Geographical Variations and Trends in Major Cancer Incidences throughout Korea during 1999-2013 / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: We aimed to describe the temporal trends and district-level geographical variations in cancer incidences throughout Korea during 1999-2013. MATERIALS AND METHODS: Data were obtained from the Korean National Cancer Incidence Database. We calculated the age-standardized cumulative cancer incidences according to sex and geographical region (metropolitan cities, provinces, and districts) for three 5-year periods (1999-2003, 2004-2008, and 2009-2013). Each quintile interval contained the same number of regions. Disease maps were created to visualize regional differences in the cancer incidences. RESULTS: Substantial differences in cancer incidences were observed according to district and cancer type. The largest variations between geographical regions were found for thyroid cancer among both men and women. There was little variation in the incidences of stomach, colorectal, and lung cancer according to geographical region. Substantially elevated incidences of specific cancers were observed in Jeollanam-do (thyroid); Daejeon (colorectum); Jeollanam-do, Gyeongsangbuk-do, and Chungcheongbuk-do (lung); Seocho-gu, Gangnam-gu and Seongnam, Bundang-gu (breast and prostate); Chungcheong and Gyeongsang provinces (stomach); Ulleung-gun and the southern districts of Gyeongsangnam-do and Jeollanam-do (liver); and along the Nakdonggang River (gallbladder and biliary tract). CONCLUSION: Mapping regional cancer incidences in Korea allowed us to compare the results according to geographical region. Our results may facilitate the development of infrastructure for systematic cancer incidence monitoring, which could promote the planning and implementation of region-specific cancer management programs.

Altitud geográfica de residencia y dependencia alcohólica en pobladores peruanos / Geographic Altitude of Residence and Alcohol Dependence in a Peruvian Population

El objetivo de este estudio es determinar la relación entre la dependencia alcohólica y la altitud de residencia en once poblados de dos zonas altitudinales del Perú. Se realizó un estudio transversal analítico aplicando una encuesta por médicos que hasta 2013 realizaron atención primaria de salud en once poblados, que se clasificaron en zonas de baja altitud (≤ 2.500 msnm) y gran altitud (> 2.500 msnm). A los que respondieron afirmativamente a la pregunta de si consumían bebidas alcohólicas, se les aplicó el test CAGE para alcoholismo (punto de corte, ≥ 2). Con los modelos lineales generalizados, se obtuvieron los estadísticos de asociación. De los 737 participantes, el 51% eran mujeres y la mediana de edad, 36 [intervalo intercuartílico, 25-50] años 334 (45%) vivían en baja altitud y 113 (15%) tenían dependencia alcohólica. La mayor frecuencia de alcoholismo se asoció positivamente con ser de un poblado considerado como extremadamente pobre (razón de prevalencia ajustada [RPa] = 2,42; intervalo de confianza del 95%, [IC95%], 1,40-4,19); mientras que, ser mujer (RPa = 0,44; IC95%, 0,23-0,89) y residir a gran altitud (RPa = 0,15; IC95%, 0,07-0,31) se asociaron negativamente, ajustando por nueve variables sociolaborales y patológicas. Según estos datos, hay mayor frecuencia de dependencia al alcohol entre los varones, los extremadamente pobres y residentes a baja altitud. Los profesionales que realizan atención primaria y los implicados en el cuidado de la salud mental deben tomarlo en cuenta por sus implicaciones para la sociedad.

The aim of this study was to determine the association between alcohol dependence and altitude of residence in 11 villages in two high altitude areas of Peru. An analytical cross-sectional study was performed using a survey conducted by physicians in primary health care in 11 villages until 2013, that were divided into low altitude (≤2500 m asl (above sea level)), and high altitude (>2500 m asl) areas. The CAGE test for alcoholism (cut point, ≥2) was applied to those who responded positively when asked if they consumed alcohol. Statistical associations were obtained with generalised linear models Of the 737 participants, 51% were women and the median age was 36 years [interquartile range, 25-50], 334 (45%) lived at low altitude, and 113 (15%) had alcohol dependence. The highest frequency of alcoholism was positively associated with being a village considered extremely poor (Likelihood Ratio (LP) = 2.42; 95%CI, 1.40-4.19), while being female (LP = 0.44; 95%CI, 0.23-0.89) and residing at high altitude (LP = 0.15; 95%CI, 0.07-0.31) were negatively associated. These were adjusted for nine socio-occupational and pathological variables. According to these data, there is a higher frequency of alcohol dependence in being, male, extremely poor, and residing at low altitude. These results should be taken into account by professionals who work in primary care and those involved in mental health care, because of their implications in society.

Associations between Exposure to Unhealthy Food Outlets Within Residential District and Obesity: Using Data from 2013 Census on Establishments and 2013-2014 Korea National Health and Nutrition Examination Survey / 대한지역사회영양학회지

OBJECTIVES: Environmental, social and personal factors influence eating patterns. This study aimed to investigate the relationship between unhealthy food outlets within a residential area and obesity using nationally representative Korean survey data and data from the Census on Establishments. METHODS: Data on the food intakes and socioeconomic variables of a total of 9,978 adults aged ≥ 19 years were obtained from the 2013-2014 Korea National Health and Nutrition Examination Survey. Geographic locations of restaurants were obtained from the 2013 Census on Establishments in Korea. Administrative area was categorized into tertiles of count of unhealthy food outlets based on the distribution of number of unhealthy food outlets among all urban (Dong) and rural (Eup or Myun) administrative districts in Korea. Multilevel logistic regressions model were used to assess the association between the number of unhealthy food outlets and obesity. RESULTS: People living in the district with the highest count of unhealthy food outlets had higher intakes of fat (45.8 vs. 44.4 g/day), sodium (4,142.6 vs. 3,949.8 mg/day), and vitamin A (753.7 vs. 631.6 µgRE/day) compared to those living in the district with the lowest count of unhealthy food outlets. A higher count of unhealthy food outlets was positively associated with frequent consumption of instant noodles, pizza, hamburgers and sandwiches, sweets and sour pork or pork cutlets, fried chicken, snacks, and cookies. Higher exposure to unhealthy food outlets was associated with increased odds of obesity (1st vs. 3rd tertile; OR 1.689; 95% CI 1.098-2.599). CONCLUSIONS: A high count of unhealthy food outlets within a residential area is positively associated with the prevalence of obesity in Korea. The results suggest that food environmental factors affects the health outcomes and interventions aiming to restrict the availability of unhealthy food outlets in local neighborhoods may be a useful obesity prevention strategy.

Multilocus sequence typing analysis of Pseudomonas aeruginosa isolated from pet Chinese stripe-necked turtles (Ocadia sinensis) / 한국실험동물학회지

Our research sought to characterize the phylogeny of Pseudomonas aeruginosa isolated from pet Chinese stripe-necked turtles (Ocadia sinensis) to better understand its evolutionary relation to other isolates and increase understanding of a potential zoonotic pathogen transmitted through direct contact with pet turtles. Thirty-one Pseudomonas aeruginosa isolates were obtained from both immature and adult turtles sold in pet shops in Korea. To characterize the phylogenic position of Chinese stripe-necked turtle-borne P. aeruginosa relative to other strains, multilocus sequence typing (MLST) analysis was performed due to the accessibility and breadth of MLST databases. Seven housekeeping genes (acsA, aroE, guaA, mutL, nuoD, ppsA, and trpE) were sequenced and the results were compared with data from the MLST database. The genes were further used for phylogenetic analysis of P. aeruginosa using concatenated gene fragments. Both rooted and unrooted phylogenetic trees were generated. Eleven distinct sequence types were present within the isolates among which seven were new. Expanding an unrooted phylogenetic tree to include P. aeruginosa MLST sequences isolated from various other geographic locations and sources revealed a divergent cluster containing the majority of isolates obtained from turtles. This suggests that P. aeruginosa strains particularly well-adapted for inhabiting turtles occupy a distinct phylogenetic position.

Epidemiology of Oral Lichen Planus in a Cohort of South Indian Population: A Retrospective Study

BACKGROUND: Oral lichen planus (OLP) is an immune-mediated potentially malignant disorder of the oral cavity. Dysplastic OLP has an altered cytogenic profile and can progress into oral squamous cell carcinoma. The epidemiology of OLP is well-described in several relatively large series from various geographic locations, whereas such series from southern India is rare. The aim of the present study was to determine the epidemiology of OLP in a cohort of South Indian population. METHODS: All the case data records of 29,606 patients who visited Mar Baselios Dental College and Hospital, Kerala, India from 2014 to 2015 were retrospectively reviewed. For data review, 122 patients of OLP were selected Estimated were type, number, and location of lesions, clinical manifestation, age of the patient, gender, onset and duration of lesion, stressful life style, habits, skin involvement and associated systemic illness, and presence/absence of dysplasia. RESULTS: When the distribution of OLP among the gender was considered, we found more prevalence in females than males. Fifty-seven percent of patients were associated with stressful lifestyle. Reticular lichen planus was the most common clinical subtype found. Bilateral buccal mucosal was the common site, when the distribution of sites of OLP were compared (P < 0.05). Hypersensitivity reaction was frequently associated with systemic illness with OLP (P < 0.05). Anaplasia was found among 5% of lichen planus lesions. CONCLUSIONS: OLP patients had high incidence of hypersensitivity reactions and 5% of OLP lesions showed anaplasia. Long term follow-up is necessary to monitor the recurrence, prognosis, and malignant transformation of OLP.

Reassessing the Usefulness of Coronary Artery Calcium Score among Varying Racial and Ethnic Groups by Geographic Locations: Relevance of the Korea Initiatives on Coronary Artery Calcification Registry

There is some disparity in the morbidity and mortality rates of cardiovascular disease (CVD) according to race, ethnicity, and geographic regions. Although prediction algorithms that evaluate risk of cardiovascular events have been established using traditional risk factors, they have also demonstrated a number of differences along with race and ethnicity. Of various risk assessment modalities, coronary artery calcium (CAC) score is a sensitive marker of calcific atherosclerosis and correlates well with atherosclerotic plaque burden. Although CAC score is now utilized as a useful tool for early detection of coronary artery disease, prior studies have suggested some variability in the presence and severity of coronary calcification according to race, ethnicity, and/or geographic regions. Among Asian populations, it would appear necessary to reappraise the utility of CAC score and whether it remains superior over and above established clinical risk prediction algorithms. To this end, the Korea initiatives on coronary artery calcification (KOICA) registry has been designed to identify the effectiveness of CAC score for primary prevention of CVD in asymptomatic Korean adults. This review discusses the important role of CAC score for prognostication, while also describing the design and rationale of the KOICA registry.

Seasonal and regional variations in the causes of anaphylaxis in Korean adults

PURPOSE: To investigate whether causes of anaphylaxis vary according to regions and seasons in Korean adults. METHODS: Based on previous retrospective studies of anaphylaxis between 2007 and 2011 at the 15 university hospitals. Regions were classified into 4 groups: region I, Seoul; region II, Gyeonggi; region III, Chungcheong; and region IV, Chonnam and Busan. The cases induced by 5 major allergens including drugs, food, bee sting, radiocontrast media, and exercise, were analyzed in the present study. RESULTS: Among a total of 1,661 cases reported (53% male, 45.9+/-16.0 years), 367 (22.2%), 706 (42.5%), 319 (19.2%), and 269 cases (16.2%) were enrolled in regions I, II, III, and IV, respectively. Of the 5 major allergens, drugs (37.3%) were the most frequently reported, followed by food (25.7%), bee sting (17.9%), radiocontrast media (12.9%), and exercise (6.2%). There was no significant difference in the total occurrence of anaphylaxis in 4 seasons (374 in spring, 460 in summer, 460 in autumn, and 367 in winter). Multiple logistic regression analysis revealed that drug-induced anaphylaxis was significantly associated with the winter season (odds ratio [OR] 1.0 vs. OR 0.597, P<0.05 for spring; OR 1.0 vs. OR 0.481, P<0.01 for summer; OR 1.0 vs. OR 0.653, P<0.05 for autumn). Food-associated anaphylaxis was mainly reported in region I, whereas the frequency of insect sting was relatively higher in regions II, III, and IV than in region I. Older age and female gender were significantly associated with drug-induced anaphylaxis. CONCLUSION: Specific causative allergens of anaphylaxis in adults may vary according to age, gender, region, and season in Korea.

A evolução do Congresso Brasileiro de Atividade Física e Saúde. Copo meio cheio ou meio vazio? / The evolution of the Brazilian Congress on Physical Activity and Health. Glass half full or half empty?

O objetivo do presente estudo foi resgatar a memória do Congresso Brasileiro de Atividade Física e Saúde (CBAFS) e descrever a evolução da participação no evento segundo localização geográfica da afiliação dos participantes, eixos de pesquisa, e tipo de estudo dos resumos apresentados. A pesquisa foi realizada nos anais das nove edições do CBAFS. Buscou-se identificar o estado (convidados nacionais) e país (convidados internacionais) de origem dos palestrantes, estado de origem do primeiro autor, delineamento de estudo e eixos de pesquisa em atividade física e saúde (em que a atividade física e/ou o comportamento sedentário são exposição ou desfecho do estudo). Os dados foram apresentados em frequências absolutas, relativas e taxas brutas por milhão de habitantes. Em todos os anos foi observada uma predominância de palestrantes e de resumos da região Sul do país, seguido das regiões Sudeste e Nordeste. Quanto aos palestrantes internacionais houve participação da América do Norte (EUA, Canadá), Europa (Portugal, França, Finlândia e Dinamarca) e Colômbia. Para o conteúdo dos resumos há predominância de delineamentos transversais sobre as consequências da atividade física/comportamento sedentário na saúde, determinantes da prática de atividade física e estudos descritivos sobre nível/tendência de atividade física. O eixo de intervenções para aumento dos níveis de atividade física e diminuição do comportamento sedentário permanecem insipientes. Conclui-se que há grande disparidade geográfica em relação aos congressistas e dificuldades em traduzir as evidências em aumento nos níveis de atividade física. Entretanto, tem sido observada uma melhora em relação a representação geográfica e crescente número de participantes.

The aim of this study was to rescue the history of the Brazilian Congress of Physical Activity and Health (CBAFS) and describe the evolution of the event according to participants' geographical location of the affiliation, research axes, and type of study presented in abstracts. The survey was conducted in annals of all nine CBAFS editions. We sought to identify the state (national guests) and country (international guests) of speakers' origin, as well as first author state, study design and research lines in physical activity and health (where physical activity and/or sedentary behavior are exhibition or study endpoint). The data were presented as absolute, relative and crude rates per million population frequencies. In all years a predominance of speakers and abstracts of the Southern region, followed by the Southeast and Northeast regions was observed. Regarding international speakers there was participation from North America (USA, Canada), Europe (Portugal, France, Finland and Denmark) and Colombia. For the content of the abstracts there was a predomination of cross-sectional designs on the physical consequences of physical activity/sedentary behavior, determinants of physical activity and level of descriptive studies on levels/trends of physical activity. The axis of interventions to increase levels of physical activity and decrease sedentary behavior remained ignored. Concluded that there is still great geographical disparity in relation to congressmen and difficulties in translating evidence into increased levels of physical activity. However, an improvement has been observed in relation to geographical representation and growing number of participants'.

Isla del Coco, on Cocos Plate, converges with Isla de San Andrés, on the Caribbean Plate, at 78mm/yr / La Isla del Coco, en la Placa de Cocos, converge con la Isla de San Andrés, en la Placa del Caribe, a 78 mm/año

Isla del Coco is the only land mass of the Cocos Plate that emerges above sea level. This makes it the only place where Cocos Plate motion can be measured using Global Navigation Satellite System (GNSS) monitoring. Global Positioning System (GPS) observations have been carried out sporadically over more than two decades on Isla del Coco, allowing precise measurement of the motion of the Cocos Plate. Recently, in May 2011, a continuous GPS station was built and instrumented at Isla del Coco, in Wafer Bay, by OVSICORI-UNA and UNAVCO, as part of the COCONet regional GNSS network. Position time series from this CGPS station (ISCO: Isla del Coco) show a steady motion of Isla del Coco at a speed of 90.9±1.5mm/yr in the N35oE direction in ITRF2008 and convergence with the Caribbean Plate at 78±1mm/yr. This result is consistent with the findings of the earliest GPS studies, and agrees within uncertainty with the estimated convergence rate of 76.4±x mm/ yr of the MORVEL plate motion model. MORVEL is based on an average over the last 780,000 years, and our result suggests that Cocos-Caribbean plate motions have been constant over that time interval.

La Isla del Coco es la única porción emergida en la placa del Coco. Esta condición la hace el único lugar donde se puede medir, usando Sistemas de Navegación Global por Satélite (GNSS), la velocidad de dicha placa. Las mediciones con GPS en la Isla del Coco se han realizado por más de dos décadas, permitiendo obtener velocidades precisas. En mayo del 2001 se instaló una estación continua de GPS en la Isla del Coco como parte, tanto de la Red Regional de GNSS COCONet, como del Sistema de Monitoreo Geodinámico de Nicoya (SISMOGENICO). Resultados de esta estación continua muestran movimiento continuo de la Isla del Coco, con respecto a ITRF2008, a una velocidad de 90.9±1.5mm/año con dirección N35oE y convergencia con la placa del Caribe a 78±1mm/año. Estas velocidades son consistentes con las obtenidas por MORVEL, un modelo geológico de velocidades de placas representativo de los últimos 780,000 años, y sugieren que la convergencia de estas placas se ha mantenido constante durante ese lapso de tiempo.
