The evaluation of global epidemic of HIV/AIDS with a novel approach using country-specific counts of HIV infections and three rates controlled for population and geographic area / 《全球健康杂志（英文）》

Background:The human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) epidemic is a typical global health concern.The impact of HIV/AIDS is global,and we cannot effectively solve the problem without a global effort.In this study,we report our research on global HIV/AIDS control with an innovative fourdimensional approach.Methods:Countries (n=148) with data available on area size,total population,and the total number of persons living with HIV (PLWH) were included.The HIV epidemic across the globe was described using 4 indicators,including the total count,population-based P rate,geographic area-based G rate,and population and geographic area-based PG rate.Results:A total of 35,426,911 PLWH were included,with a global prevalence rate of 0.51 per 1,000 population.The total PLWH count provided data on resource allocation in individual countries to improve HIV/AIDS care;and the top five countries with the highest PLWH counts were South Africa (7,000),Nigeria (3,500),India (2,100),Kenya (1,500),and Mozambique (1,500).The other three indicators provide a measure to assess the global risk profile of HIV transmission and to provide information on HIV/AIDS prevention strategies.The top five countries with the highest P rates (per 1,000 persons) were Swaziland (170.9),Botswana (154.7),Lesotho (145.2),South Africa (127.4),and Zimbabwe (89.7);the top five countries with the highest G rates (per 100 km2) were Swaziland (1,279.1),Malawi (1,039.5),Lesotho (1,021.1),Rwanda (810.7),and Uganda (748.1);and the top five countries with highest PG rates (per 1,000,000 persons per 100 km2) were Barbados (2,127.9),Swaziland (993.8),Lesotho (478.3),Malta (375.0),and Mauritius (319.7).With PG rate,we detected countries in two hotspots (south and middle Africa and the Caribbean region) and one belt across the Euro-Asian region with high risks of HIV transmission.Conclusions:This study expanded the conventional measures by adding two new indicators,thus forming a new four-dimensional framework to quantify the global HIV epidemic.In addition to gaining a better insight into the epidemic than before,study findings provide new data on country-level and global efforts to end the AIDS epidemic by 2030.

Decreasing prevllence of the acute/subacute cliical form of paracoccidioidomyccosis in mato grosso do sul state, Braiil / Reducao na prevalencia da forma aguda/subaguda da paracoccidioidomicose em Mato Grosso do Sul, Brasil

With the objective to evaluate the behavior of paracoccidioidomycosis in the last three decades, clinical and epidemiological data of 595 patients admitted to clinical services of the Federal University of Mato Grosso do Sul from 1980 to 2009 were investigated. Gender, age distribution, clinical form, comorbidity with tuberculosis or AIDS, and mortality were compared by decades of clinical admission. It was shown that during the three decades there was a decrease in women percentage, and the same manner occurred a reduction in participants in the age group of 20 to 39 years. Moreover, the acute/subacute forms have been diminished in the period. These fluctuations are closely related and can be simultaneously analyzed. Increased AIDS co-infection prevalence from the first to the second decade was also revealed, coinciding with the appearance of the retroviral epidemic and stabilizing during the third decade. No change in the tuberculosis co-infection rate was observed (overall = 6.9%). It reinforces the importance of this co-morbidity. The overall mortality rate remained steady at 6.7%, not varying significantly from one decade to another. The persistent mortality rate calls attention to the importance of this neglected disease.

Com o objetivo de avaliar o comportamento da paracoccidioidomicose nas últimas três décadas, dados clínicos e epidemiológicos de 595 pacientes atendidos dentre 1980 a 2009 no Hospital da Universidade Federal de Mato Grosso do Sul foram estudados. Sexo, faixa etária, forma clínica, associação com tuberculose ou AIDS e mortalidade foram comparados por década em que a doença foi diagnosticada. Observou-se, nas três décadas do estudo, uma redução do percentual de mulheres, de pacientes do grupo de 20 a 39 anos, assim como de casos com a forma aguda/subaguda. Estas alterações estão intimamente relacionadas e podem ser analisadas simultaneamente. Houve aumento de casos de coinfecção com AIDS da primeira para segunda década, coincidindo com o surgimento da epidemia, e manteve-se estável durante a década seguinte. Não houve alteração da taxa de coinfecção com tuberculose, que no geral foi de 6,9% o que reforça a importância desta comorbidade. A taxa geral de mortalidade foi de 6,7% e também não variou entre as décadas estudadas. A manutenção da taxa de óbitos chama a atenção para a relevância dessa doença negligenciada.

Comparisons of Health Inequalities in Small Areas with Using the Standardized Mortality Ratios in Korea / 예방의학회지

OBJECTIVES: This study was performed to compare the standardized mortality ratios among different small areas and to explore the usefulness of standardized mortality ratios in South Korea. METHODS: To calculate the standardized mortality ratio (SMR), we obtained the national deaths certificate data (2004-2006) and national registration population data (2003-2006), and these were provided by the National Statistical Office. The small areas (Eup.Myoun.Dong) were based on the subdivisions of counties. Among the 3,580 small areas classified by the National Statistical Office, 3,571 areas were included in this study. The basic statistics and decile distributions of the SMRs for all the regional levels were calculated, and the small area maps were also produced for some selected regions. To evaluate the precision of SMR, we calculated the 95% confidence intervals of the SMR in selected small areas. RESULTS: The mean and the standard deviation of the SMRs among all small areas were 100.8 and 17.0, respectively. The range was 30.6-211.7 and the inter-quartile range was 20.7. Seoul metropolitan city displayed the lowest mean SMR among 16 regions in South Korea, and 34.6 percent of the small area SMRs belonged to the first decile(the lowest group). On the contrary, the mean SMR of Gyeongsangnam province was highest, and 26.1 percent of the small area SMRs belonged to the tenth decile(the highest group). In some areas, the precision of the SMR, which was calculated by the 95% confidence intervals, remained questionable, yet it was quite stable for almost areas. CONCLUSIONS: The standardized mortality ratios can be useful for allocating health resources at the small area level in Korea.
