Análise da internação e mortalidade por HIV no Brasil, 2016-2020 / Analysis of hospitalization and HIV mortality in Brazil, 2016-2020 / Análisis de la hospitalización y la mortalidad por VIH en Brasil, 2016-2020

Apesar dos avanços programáticos conquistados na atenção às pessoas que vivem com HIV no Brasil, os índices de morbimortalidade atribuídos à infecção ainda são altos e heterogêneos no território nacional. Destarte, entende-se que os aspectos epidemiológicos do HIV devam ser analisados em consonância com as características e delimitações geográficas. Este estudo objetivou analisar os coeficientes de internação hospitalar e de mortalidade por HIV, segundo regiões do Brasil, de 2016 a 2020. Tratou-se de um estudo ecológico das regiões brasileiras, com dados extraídos das plataformas públicas de informação, referentes ao período de 2016 a 2020. Procedeu-se a análise por meio de estatística descritiva e, baseado nos coeficientes regionais de internação hospitalar e mortalidade calculados, foram derivadas ilustrações geográficas por meio do software QGIS, a partir do mapa do Brasil, divisado por regiões. Os resultados apontaram que as internações por HIV apresentaram queda em todas as regiões ao longo do período, contudo, o Sudeste se manteve abaixo da média nacional. Com relação aos óbitos, a queda foi observada em todas as regiões, com menor variação no Nordeste e Norte. Ademais, as regiões Sul e Norte seguiram com os maiores coeficientes de mortalidade do país durante todo o período analisado, enquanto as demais ficaram abaixo da média nacional. Pontua-se a necessidade de novas investigações quanto às especificidades regionais de conformação e organização da rede de atenção no que se refere à oferta de ações e serviços de saúde, bem como das condições socioeconômicas e comportamentais que influem no curso da infecção pelo HIV.

A pesar de los avances programáticos alcanzados en la atención de las personas que viven con el VIH en Brasil, las tasas de morbilidad y mortalidad atribuidas a la infección aún son elevadas y heterogéneas en el territorio nacional. Así, se entiende que los aspectos epidemiológicos del VIH deben ser analizados de acuerdo con las características y límites geográficos. Este estudio tuvo como objetivo analizar los coeficientes de hospitalización y mortalidad por VIH, según regiones de Brasil, de 2016 a 2020. Se trata de un estudio ecológico de regiones brasileñas, con datos extraídos de plataformas de información pública, referentes al período de 2016 a 2020. El análisis se realizó mediante estadística descriptiva y, a partir de los coeficientes de ingreso hospitalario regional y mortalidad calculados, se derivaron ilustraciones geográficas utilizando el software QGIS, a partir del mapa de Brasil, dividido por regiones. Los resultados mostraron que las hospitalizaciones por VIH disminuyeron en todas las regiones en el período, sin embargo, el Sudeste se mantuvo por debajo del promedio nacional. En cuanto a las muertes, la caída se observó en todas las regiones, con menor variación en el Nordeste y Norte. Además, las regiones Sur y Norte continuaron presentando las tasas de mortalidad más altas del país durante todo el período analizado, mientras que las demás se ubicaron por debajo del promedio nacional. Existe la necesidad de mayores investigaciones sobre las especificidades regionales de conformación y organización de la red de atención en lo que se refiere a la provisión de acciones y servicios de salud, así como las condiciones socioeconómicas y conductuales que influyen en el curso de la infección por el VIH.

Despite the programmatic advances achieved in the care of people living with HIV in Brazil, the morbidity and mortality rates attributed to the infection are still high and heterogeneous in the national territory. Thus, it is understood that the epidemiological aspects of HIV should be analyzed in accordance with the characteristics and geographical boundaries. This study aimed to analyze the coefficients of hospitalization and mortality from HIV, according to regions of Brazil, from 2016 to 2020. This was an ecological study of Brazilian regions, with data extracted from public information platforms, referring to the period 2016 to 2020. The analysis was performed using descriptive statistics and, based on the calculated regional hospital admission and mortality coefficients, geographic illustrations were derived using the QGIS software, from the map of Brazil, divided by regions. The results showed that hospitalizations for HIV decreased in all regions over the period; however, the Southeast remained below the national average. Regarding deaths, the drop was observed in all regions, with less variation in the Northeast and North. Furthermore, the South and North regions continued to have the highest mortality rates in the country throughout the analyzed period, while the others were below the national average. There is a need for further investigations regarding the regional specificities of conformation and organization of the care network with regard to the provision of health actions and services, as well as the socioeconomic and behavioral conditions that influence the course of HIV infection.

Snow's case revisited: new tool in geographic profiling of epidemiology

Abstract Geographic Profiling technique is used to find the origin of a series of crimes. The method was recently extended to other fields. One of the best renowned data in epidemiology is that by John Snow during an outburst of cholera in London. We wrote Python scripts to perform the analyses to apply the Geographic Profiling for individuating the starting origin of an infection by using the old Snow's data set. We modified the method by applying a weight to each point of the map where cases of cholera were reported. The weight was proportional to the number of cases in a given location.This modification of the Geographic Profiling method allowed to individuate in the map an area of maximum probability of the infection source, which was a few meters wide and including the historically known source of cholera, that is the "classical" water pump at Broad Street.The method appears to be a useful complement in order to individuate the source of epidemics when available data about the cases of the infections can be summarized on a map.

Cartography of neoplasms in dogs from different regions of the city of São Paulo, SP, Brazil: a survey (2002-2003) of data from the Veterinary Hospital of the School of Veterinary Medicine and Animal Science of the University of São Paulo, Brazil / Cartografia das neoplasias em cães das diferentes regiões da cidade de São Paulo, SP, Brasil: um levantamento (2002-2003) dos dados do Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da Universidade de São Paulo, Brasil

Improvements in veterinary medicine have resulted in a significant benefit in the life of pets in the last 20 years, and increased pet life expectancy led to an increased prevalence of canine neoplasia. Cancer epidemiology and spatial analysis tools, although well developed for human oncology research, is just beginning to be explored in veterinary oncology. São Paulo city, capital of the state of São Paulo, Brazil, is divided into five regions: North, South, East, West and downtown. The Veterinary Hospital of the School of Veterinary Medicine and Animal Science, University of São Paulo (HOVET-SVMAS-USP), is located in the West region of São Paulo, Brazil, and admits cases of small and large animals. Canine mammary tumors are so numerous that they are not routinely treated at the HOVET. The aim of this work was to perform a cartographic study to describe the spatial distribution of prevalent cases of neoplasms in dogs from the HOVET. Of the 3,620 cases seen in 2002 and 2003, 380 cases (10.5%) were of dogs affected with benign and malignant neoplasms. No statistical difference was found for the 380 addresses distributed among the five regions of the city. These results showed that the HOVET receives canine patients from all regions of São Paulo and there is a homogeneous spatial distribution of neoplasms. Authors encourage additional broader studies, involving several veterinary hospitals, clinics or laboratories in order to obtain more accurate data on distribution of canine neoplasms in São Paulo, SP, Brazil.

Avanços na medicina veterinária resultaram em benefícios significativos na vida de animais de estimação nos últimos 20 anos, e o aumento da expectativa de vida para animais levou a uma maior prevalência de neoplasias em cães. A Epidemiologia do Câncer e as ferramentas de análise espacial, embora bem desenvolvidas na pesquisa oncológica humana, estão começando a serem exploradas na Oncologia Veterinária. A cidade de São Paulo, capital do estado de São Paulo, Brasil, é dividida em cinco regiões: Norte, Sul, Leste, Oeste e centro. O Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da Universidade de São Paulo (HOVET-SVMAS-USP) está localizado na região Oeste de São Paulo, Brasil, e admite casos de pequenos e grandes animais. Tumores mamários caninos são tão numerosos que não são tratados na rotina do HOVET. O objetivo deste trabalho foi realizar um estudo cartográfico para descrever a distribuição espacial dos casos prevalentes de neoplasias em cães a partir do HOVET. Dos 3.620 casos atendidos em 2002 e 2003, 380 (10,5%) casos eram de cães acometidos por tumores benignos e malignos. Não foi encontrada diferença estatística entre a distribuição dos 380 endereços entre as cinco regiões da cidade. Os resultados mostraram que o HOVET atende pacientes caninos de todas as regiões de São Paulo e que há uma distribuição espacial homogênea das neoplasias. Os autores incentivam estudos mais amplos, envolvendo vários hospitais veterinários, clínicas e laboratórios, a fim de obter dados mais precisos sobre a distribuição das neoplasias caninas em São Paulo, SP, Brasil.

High Malaria Prevalence among Schoolchildren on Kome Island, Tanzania

In order to determine the status of malaria among schoolchildren on Kome Island (Lake Victoria), near Mwanza, Tanzania, a total of 244 schoolchildren in 10 primary schools were subjected to a blood survey using the fingerprick method. The subjected schoolchildren were 123 boys and 121 girls who were 6-8 years of age. Only 1 blood smear was prepared for each child. The overall prevalence of malaria was 38.1% (93 positives), and sex difference was not remarkable. However, the positive rate was the highest in Izindabo Primary School (51.4%) followed by Isenyi Primary School (48.3%) and Bugoro Primary School (46.7%). The lowest prevalence was found in Muungano Primary School (16.7%) and Nyamiswi Primary School (16.7%). These differences were highly correlated with the location of the school on the Island; those located in the peripheral area revealed higher prevalences while those located in the central area showed lower prevalences. Plasmodium falciparum was the predominant species (38.1%; 93/244), with a small proportion of them mixed-infected with Plasmodium vivax (1.6%; 4/244). The results revealed that malaria is highly prevalent among primary schoolchildren on Kome Island, Tanzania, and there is an urgent need to control malaria in this area.

The changing distribution of malaria in the Brazilian Amazon, 2003-2004 and 2008-2009

Introduction More than half of the malaria cases reported in the Americas are from the Brazilian Amazon region. While malaria is considered endemic in this region, its geographical distribution is extremely heterogeneous. Therefore, it is important to investigate the distribution of malaria and to determine regions whereby action might be necessary. Methods Changes in malaria indicators in all municipalities of the Brazilian Amazon between 2003-2004 and 2008-2009 were studied. The malaria indicators included the absolute number of malaria cases and deaths, the bi-annual parasite incidence (BPI), BPI ratios and differences, a Lorenz curve and Gini coefficients. Results During the study period, mortality from malaria remained low (0.02% deaths/case), the percent of municipalities that became malaria-free increased from 15.6% to 31.7%, and the Gini coefficient increased from 82% to 87%. In 2003, 10% of the municipalities with the highest BPI accumulated 67% of all malaria cases, compared with 2009, when 10% of the municipalities (with the highest BPI) had 80% of the malaria cases. Conclusions This study described an overall decrease in malaria transmission in the Brazilian Amazon region. As expected, an increased heterogeneity of malaria indicators was found, which reinforces the notion that a single ...

Paracoccidioidomycosis in a western Brazilian Amazon State: Clinical-epidemiologic profile and spatial distribution of the disease

Introduction: Paracoccidioidomycosis (PCM) is a systemic infection caused by the fungus Paracoccidioides brasiliensis. PCM is considered one of the most important systemic mycoses in Latin America. Methods: This is a clinical, epidemiological, retrospective, quantitative study of PCM cases in patients attending the National Health Service in the State of Rondônia in 1997-2012. The examined variables included sex, age group, year of diagnosis, education level, profession, place of residence, diagnostic test, prior treatment, medication used, comorbidities and case progress. Results: During the study period, 2,163 PCM cases were registered in Rondônia, and the mean annual incidence was 9.4/100,000 people. The municipalities with the highest rates were located in the southeastern region of Rondônia, and the towns of Pimenteiras do Oeste and Espigão do Oeste had the highest rates in the state, which were 39.1/100,000 and 37.4/100,000 people, respectively. Among all cases, 90.2% and 9.8% were observed in men and women, respectively, and most cases (58.2%) were observed in patients aged between 40 and 59 years. Itraconazole was used to treat 91.6% (1,771) of cases, followed by sulfamethoxazole in combination with trimethoprim (4.4% [85] of cases). One hundred thirty-one (6%) patients died. Conclusions: The State of Rondônia has a high incidence of PCM, and the municipalities in the southeastern region of the state were found to have the highest incidence rates of this disease. Our findings suggest that Rondônia is the state in the northern region with the highest mortality rate for PCM. .

Origem e territorio de distribuição da artéria cerebral média em javali (Sus scrofa scrofa Linnaeus, 1758) / Origin and distribution of territory in middle cerebral artery wild boar (Sus scrofa scrofa Linnaeus, 1758)

Foram estudados 20 encéfalos de javali (Sus scrofa scrofa), adultos, 14 fêmeas e oito machos, com o sistema arterial corado com látex e fixados por solução aquosa de formaldeído a 10%. A artéria cerebral média em ambos os antímeros, originou-se no ramo rostral da artéria carótida do encéfalo (100%), sendo representado geralmente por dois a cinco vasos arteriais que dirigiram-se laterodorsalmente atingindo a região do trígono olfatório assim como o sulco rinal lateral, preenchendo, no entanto, a fissura transversa do cérebro e distribuindo-se nas porções lateral, dorsolateral, caudolateral e rostrolateral do hemisfério cerebral. O número de vasos arteriais relativos a artéria cerebral média, no antímero direito foi em dois modelos (10% ) a presença de duas artérias, em 13 modelos (65%) a presença de três artérias, em quatro modelos (20%) a presença de quatro artérias e em um modelo (5% ) a presença de cinco artérias. Já no antímero esquerdo encontraram-se em quatro modelos (20% ) a presença de duas artérias, em nove modelos (45%) a existência de três artérias, em seis modelos (30%) a presença de quatro artérias e em um modelo (5%) a presença de cinco artérias.

We studied 20 brains of wild boar (Sus scrofa scrofa), adults, 14 females and 08 males, colored latex and fixed in aqueous 10% formaldehyde. The middle cerebral artery on both the sides, has its origin in the rostral branch of the carotid artery of the brain (100%), and generally represented by two to five arteries who went laterodorsalmente reaching the region of the olfactory trigone and the rhinal sulcus lateral filling but the transverse fissure and distributing the lateral portions, dorsolateral, rostrolateral and caudolateral hemisphere. The number of blood vessels on the middle cerebral artery, was in the right antimere two models (10%) the presence of two arteries, 13 models (65%) the presence of three arteries in models (20%) the presence of four arteries and a model (5%) the presence of five arteries. In the left antimere met fourth models (20%) the presence of two arteries, 9 models (45%) the existence of three arteries, in the sixth models (30%) the presence of four arteries and a model (5 %) the presence of five arteries.

Prevalence of Intestinal Helminths among Inhabitants of Cambodia (2006-2011)

In order to investigate the status of intestinal helminthic infections in Cambodia, epidemiological surveys were carried out on a national scale, including 19 provinces. A total of 32,201 fecal samples were collected from schoolchildren and adults between 2006 and 2011 and examined once by the Kato-Katz thick smear technique. The overall egg positive rate of intestinal helminths was 26.2%. The prevalence of hookworms was the highest (9.6%), followed by that of Opisthorchis viverrini/minute intestinal flukes (Ov/MIF) (5.7%), Ascaris lumbricoides (4.6%), and Trichuris trichiura (4.1%). Other types of parasites detected were Enterobius vermicularis (1.1%), Taenia spp. (0.4%), and Hymenolepis spp. (0.2%). The northwestern regions such as the Siem Reap, Oddar Meanchey, and Banteay Meanchey Provinces showed higher prevalences (17.4-22.3%) of hookworms than the other localities. The southwestern areas, including Koh Kong and Preah Sihanouk Provinces showed higher prevalences of A. lumbricoides (17.5-19.2%) and T. trichiura (6.1-21.0%). Meanwhile, the central and southern areas, in particular, Takeo and Kampong Cham Provinces, showed high prevalences of Ov/MIF (23.8-24.0%). The results indicate that a considerably high prevalence of intestinal helminths has been revealed in Cambodia, and thus sustained national parasite control projects are necessary to reduce morbidity due to parasitic infections in Cambodia.

Breast cancer incidence and mortality in women under 50 years of age in Brazil / Incidência e mortalidade por câncer de mama em mulheres menores de 50 anos no Brasil / Incidencia y mortalidad por cáncer de mama en mujeres menores de 50 años en Brasil

Many countries have reported an increase in breast cancer incidence in young women. The current study's objective was to explore breast cancer distribution in women less than 50 years of age in Brazil. A descriptive study on breast cancer incidence (selected cities) and mortality (Brazil and selected cities) in 2002-2004 was carried out, and the results were compared with those from other countries. The study also analyzed the trend in hospital morbidity and incidence rates for breast cancer. Porto Alegre (Rio Grande do Sul State) showed the highest incidence rates (17.9 and 165.5/100,000 in the 15-39 and 40-49-year age strata, respectively). Regarding mortality, Belo Horizonte (Minas Gerais State) showed the highest rate in the 15-39-year group and Porto Alegre in the 40-49-year group (2.8 and 25.5/100,000). Hospital admissions and incidence rates for breast cancer suggest a change in epidemiological distribution. The results reveal an epidemiological pattern of breast cancer in young Brazilian women with regional distribution characteristics.

ntroducción. El dengue es una enfermedad de transmisión vectorial de gran impacto en la salud pública. La transmisión del dengue es afectada por factores entomológicos, socioculturales y económicos. Además, la variabilidad climática juega un importante papel en la dinámica de transmisión. Un amplio consenso científico ha indicado que la fuerte asociación entre la enfermedad y las variables climáticas podría ser empleada para desarrollar modelos que expliquen la incidencia de la enfermedad. Objetivo. Desarrollar un modelo que permita comprender la dinámica de transmisión del dengue en Medellín y predecir incrementos en la incidencia de la enfermedad. Materiales y métodos. Se empleó la incidencia de dengue como variable dependiente y como variables independientes, los factores climáticos (temperatura máxima, media y mínima, humedad relativa y precipitación) registrados a escala semanal. Se utilizó el programa Expert Modeler para desarrollar un modelo que explique mejor el comportamiento de la enfermedad. Mediante modelos ARIMA, se seleccionaron las variables climáticas que tuvieron una relación significativa con la variable dependiente. Resultados. El 34 % de la variabilidad observada se explicó por el modelo. La precipitación fue la variable climática que mostró una asociación estadísticamente significativa con la incidencia del dengue, pero con un rezago de 20 semanas. Conclusiones. La transmisión del dengue en Medellín se vio afectada por la variabilidad climática, en particular, por la precipitación. La fuerte asociación entre el dengue y la precipitación permitió construir un modelo que ayuda a comprender la dinámica de transmisión, información que será de gran utilidad para el desarrollo de adecuadas y oportunas estrategias de control.

Introduction: Dengue fever is a major impact on public health vector-borne disease, and its transmission is influenced by entomological, sociocultural and economic factors. Additionally, climate variability plays an important role in the transmission dynamics. A large scientific consensus has indicated that the strong association between climatic variables and disease could be used to develop models to explain the incidence of the disease. Objective: To develop a model that provides a better understanding of dengue transmission dynamics in Medellin and predicts increases in the incidence of the disease. Materials and methods: The incidence of dengue fever was used as dependent variable, and weekly climatic factors (maximum, mean and minimum temperature, relative humidity and precipitation) as independent variables. Expert Modeler was used to develop a model to better explain the behavior of the disease. Climatic variables with significant association to the dependent variable were selected through ARIMA models. Results: The model explains 34% of observed variability. Precipitation was the climatic variable showing statistically significant association with the incidence of dengue fever, but with a 20 weeks delay. Conclusions: In Medellin, the transmission of dengue fever was influenced by climate variability, especially precipitation. The strong association dengue fever/precipitation allowed the construction of a model to help understand dengue transmission dynamics. This information will be useful to develop appropriate and timely strategies for dengue control.

Results Twenty-nine pregnant lepers were studied during the study period. The detection rates (DRs) for the studied association were 4.7 in 2007, 9.4 in 2008, and 4.3 in 2009. Conclusions The Carajás region presented a medium pattern of endemicity during most of the study period, with a high DR found in 2008. .

Topografia do cone medular da irara (Eira barbara) e sua relevância em anestesias epidurais / Topography of the conus medullari in tayra (Eira barbara) and their relevance in epidural anesthesia

Encontrada principalmente na América do Sul, a irara é um carnívoro pertencente à família Mustelidae, a qual pouco se tem informações sobre sua morfologia de forma geral. Diante disso, objetivou-se conhecer melhor parte do sistema nervoso desta espécie, mais precisamente a topografia do cone medular, a fim de subsidiar intervenções anestésicas peridurais nesta, uma vez que a clínica de animais selvagens vem crescendo a cada dia. Foram estudados três exemplares machos, adultos, provenientes da área de Mina Bauxita, Paragominas, doados ao Laboratório de Pesquisa Morfológica Animal (LaPMA), Universidade Federal Rural da Amazônia (UFRA), Belém, os quais foram radiografados e dissecados ao nível lombossacral, seguido de exposição do cone medular. Este, por sua vez, situou-se entre L4-L6 possuindo comprimento médio de 4,31cm, o que nos levou a sugerir a região sacrococcígea como ponde ideal para prática de anestesias epidurais nesta espécie.

Mainly found in South America, tayra is a carnivore belonging to the Mustelidae family, of which is little information regarding its morphology in general. The study aimed to characterize the topography of the medullar cone in order to subsidize epidural anesthetic interventions, since the clinics of wild animals is growing each day. We studied three adult male tayras from the Bauxite Mine area of Paragominas, donated to the Research Laboratory of Animal Morphology, Federal Rural University of Amazonia, Belém. They were x-rayed and dissected at the lumbosacral level to expose the medullar cone, which was found between L4-L6 with an average length of 4.31cm. This led us to suggest the sacrococcygeal region as ideal site for practice of epidural anesthesia in this species.

An interesting finding was the percentage of expatriates affected was increasing over the last 10 years compared to that of the Saudis.@*CONCLUSIONS@#A definite declining trend in the incidence of CL was observed in Al Hassa. Further studies are warranted to assess whether special public health measures are needed for better control of CL in expatriate populations in Saudi Arabia.

Evaluation of reliability and reproducibility of linear measurements of cone-beam-computed tomography.

Objective: it was to evaluate intra- and interexaminer reliability and reproducibility of linear measurements in cone-beam tomography (CBCT) images. Materials and Methods: CBCT scans were obtained from 50 patients of a private clinic. Two examiners located the landmarks twice in two-dimensional and three-dimensional images on different days, with images performed 1 week apart. Intra- and interexaminer reproducibility and reliability were analyzed. Results: the measurement error (ME) did not show significant differences between intra- and interexaminers. The intraclass correlations (ICC) between the intra- and interexaminer readings obtained with the different methods showed almost perfect matches. The results demonstrated high examiner reproducibility for linear and volumetric parameters with high intraclass correlation coefficient (ICC) and coefficient of variation (CV). The ICC showed that the methodology was highly reliable and reproducible (ICC- >0.99 and CV <1.5%). Conclusion: the measurements demonstrated strong agreement between examiners and significant reliability and reproducibility. Therefore, this methodology can serve as a standard for linear measurement analysis of the topography of mandibular canal and osseous adjacent structures.

Development of Anatomy in the Edo Period: On the Publication of the Zoshi / 의사학

Chinese medicine that saw rapid development since the writing of Yellow Emperor's Canon of Internal Medicine (Hunagti Neiching) greatly influenced Korea and then Japan, firmly establishing its dominant position in the East Asian world. However, as sciences of the west were gradually imparted to East Asia, medical topography was changing little by little as well. It was Japan that actively accommodated Western medicine. During Edo Japan, many interpretation officers played an active part for exchanges with influential merchants from the Netherlands and the resultant compilation of Kaitai Shinsho in 1774 made anatomy of the West introduced to the nation in earnest. Thereafter, starting with anatomy, westernization of Japanese medicine rapidly unfolded in the nation. Accommodation of Western anatomy was enabled by the development of empirical medicine and resulting practice of dissection. Two decades before the compilation of Kaitai Shinsho, the first dissection was made in Japan and five years later, Zoshi was published by Yamawaki Toyo, triggering great controversy over dissection in the nation's medical world. It was very meaningful in that it raised a question about positivity of traditional medicine, namely, the Theory of Visceras and Bowels, and made a verification of it. Dissection of the human body that started with Yamawaki Toyo's book was faced with criticisms from Sano Yassada and through his publication of Hi Zoshi and others on one hand but it led to practice of dissection itself on the other hand. Sixteen years later a second dissection was performed by Kawaguchi Shinnin and Kaishihen was complied by him. Thereafter, western medicine was rapidly accommodated by the nation through successive dissections, publications of anatomy books, and translations of western anatomy books, and through the Meiji Restoration the medical world was reorganized into one centered on western medicine. Modern anatomy of the West was widely introduced to East Asia and at the same time Japan led a cultural attitude to massively accept Western sciences through translations. Such academic climate, which was literally called Dutch learning(Ran Gaku), made Japan reflect itself from Western perspectives and transformed East Asia's medieval world view, knowledge system, and medical thoughts.

Study on the iodine status of pregnant women and thyroid function of neonate in high iodine area / 中华预防医学杂志

<p><b>OBJECTIVE</b>To reveal the iodine status of pregnant women and its impact on thyroid function of neonates in high iodine area.</p><p><b>METHODS</b>A total of 210 pregnant women were chosen from a hospital in Haixing county, Hebei province. Pregnant women's random urinary and neonates' cord blood were collected. The urinary iodine concentration (UIC) was examined by arsenic-cerium catalytic spectrophotometry. The levels of free triiodothyronine (FT3), free thyroxine (FT4) and sensitive thyroid-stimulating hormone (sTSH) in serum were measured by chemiluminescence.</p><p><b>RESULTS</b>The age of 210 pregnant women was (27.69 +/- 4.73) years old, whose urinary iodine median (inter-quartile range ) was 1240.70 (1292.68) microg/L. 84.3% (177/210) of the pregnant women had excessive iodine intake (UIC > or = 500 microg/L), 13.8% (29/210) had more than adequate iodine intake( UIC within 250 - 499 microg/L), 0.5% (1/210) had adequate iodine intake (UIC within 150 - 249 microg/L) and 1.4% (3/210) had insufficient iodine intake (UIC < 150 microg/L). The average serum level of FT3, FT4 in neonates were (2.93 +/- 0.59), (15.03 +/- 1.92) pmol/L, respectively. The median (inter-quartile range) of serum sTSH in neonates were 7.33 (5.59) mU/L 78.1% (164/210) of the neonates' serum TSH were beyond 5 mU/L. There were no correlation between pregnant women's urinary iodine level and neonates' serum FT3 and sTSH level (P > 0.05), but there was a positive correlation between pregnant women's urinary iodine level and neonates' serum FT4 level (P < 0.01). Serum FT4 level of the neonates with whose mothers had insufficient iodine intake ((12.99 +/- 1.10) pmol/L) were statistically lower than those with their mothers had excessive iodine intake (15.16 +/- 1.83) pmol/L) (P < 0.05).</p><p><b>CONCLUSION</b>Most of the pregnant women in high iodine area were excessive for iodine nutrition, but still a few pregnant women had insufficient iodine nutrition. The level of neonates' serum sTSH were relatively high and monitoring of risk of hypothyroidism and subclinical hypothyroidism should be strengthened.</p>
