De la caracterización de la población moradora al acompañamiento en la construcción de experiencias de resistencia al despojo, en la conflictividad urbana de la ciudad de Medellín

Se sistematizan algunas iniciativas y experiencias de organización comunitaria, en proceso de construcción de territorialidad como lo son las de los participantes de la "población moradora", inmersa en los escenarios del despojo, provocado por las alianzas público-privadas del urbanismo neoliberal en el Valle de Aburrá, que al lograr convertirse en sujetos organizativos consolidan apuestas por el trabajo colectivo de transformación social. La reflexión en modo IAP da cuenta de la forma como en medio de las adversas problemáticas de su mundo de la vida, por medio del trabajo con herramientas formativas, la "población moradora" se constituye como subjetividad erguida y de resistencia, en permanente construcción de un proyecto de incidencia política.

In the midst of the advance of the urban intervention of the alliances between the officialdom and the financial guilds for the benefit of the private sector, which took place in the first two decades of the 21st century in the city of Medellín, some considerations are made on the contextual conditions in which the phenomenon of resistance of the population named dweller in the city of Medellín and the metropolitan area emerges. Thus, some initiatives and experiences of community organization are systematized, whose social subjects overcome the bets of collective work, in the midst of the adversities of the problems of their world of life of the subjectivity that lives from the dispossession by urbanism.

Greater heterogeneity was observed in treatment approaches as the treatment algorithm progressed.

Perspectives on urban mobility in promoting physical activity in the context of commuting in Brazil / Perspectivas sobre mobilidade urbana na promoção da atividade física no contexto dos deslocamentos no Brasil

Despite Brazil's important advances in regulatory aspects related to city planning, the disorder-ly growth of Brazilian cities makes it difficult to implement changes that would result in greater opportunities for the active commuting of the population. This essay was designed to reflect on opportunities for improvement in the urban environment to promote physical activity in the context of commuting in Brazil. From this perspective, the study identified policies that promote orderly growth and support active commuting in cities. It also suggested the use of indicators to evaluate and monitor development, with a particular emphasis on active commuting. Furthermore, it is essential to adapt and improve the urban planning process to meet the needs of Brazilian municipalities and foster closer collaboration with civil society. Thus, it will be possible to verify the changes in the urban environment and their impact on the active commuting, promoting the development of healthy and sustainable cities

Apesar do Brasil apresentar importante avanço em aspectos regulatórios relacionados ao planejamento das cidades, o crescimento desordenado das cidades brasileiras dificulta a realização de mudanças que reflitam em maiores oportunidades no deslocamento ativo da população. Este ensaio foi elaborado com objetivo de refletir sobre as oportunidades para melhorias no ambiente urbano para a promoção da atividade física no contexto do deslocamento no Brasil. Nessa perspectiva, o estudo identificou políticas que permitem o crescimento ordenado e favoreça o deslocamento ativo nas cidades, além de sugerir o uso de indicadores para avaliação e monitoramento do desenvolvimento, com especial foco no deslocamento ativo. Ademais, é imprescindível que o processo de planejamento urbano seja adaptado e aprimorado considerando as necessidades dos municípios brasileiros e com aproximação da sociedade civil. Assim, será possível verificar as modificações no ambiente urbano e seu impacto no deslocamento ativo da população, estimulando a criação de cidades saudáveis e sustentáveis

Representações sociais de idosos sobre a mobilidade urbana na perspectiva do direito à cidade / Social representations of the elderly about urban mobility from the perspective of the right to the city

O envelhecimento populacional e a urbanização são dois fenômenos mundiais em crescimento e representam uma das transformações sociais mais significativas do século XXI. Esse cenário exige mudanças que envolvem a de modo particular. Objetivou-se analisar as representações sociais de idosos sobre a mobilidade urbana em Chapecó (SC), na perspectiva do direito à cidade. Trata-se de uma pesquisa qualitativa, em que foram realizados levantamento documental e entrevista semiestruturada. Participaram do estudo onze idosos integrantes do Projeto SUPERidade da Secretaria de Assistência Social de Chapecó. Para a análise das informações utilizou-se a técnica de análise temática de conteúdo, delimitando-se à categoria "Medo e Insegurança na relação com as barreiras". Os sentimentos de medo e insegurança constituem as representações sociais dos idosos sobre a mobilidade urbana quando estes se deparam com barreiras, como o tempo curto no semáforo, o degrau alto do transporte público coletivo e o desrespeito por parte dos condutores de veículos, cuja interação entre elas e as limitações funcionais oriundas do envelhecimento gera tais sentimentos. Tendo em vista que o envelhecimento é um processo progressivo, irreversível e previsível no curso de vida, é o espaço urbano que pode ser redimensionado e, assim, contribuir para a inclusão de idosos com diferentes graus de capacidade funcional no cotidiano da cidade. Eliminar as barreiras significa compensar as limitações funcionais e promover um espaço urbano mais justo, democrático e saudável.(AU)

Population aging and urbanization are two growing global phenomena and represent one of the most significant social transformations of the 21st century. This scenario requires changes that involve urban mobility, which is experienced by the elderly in a particular way. The objective was to analyze the social representations of the elderly about urban mobility in Chapecó-SC from the perspective of the right to the city. This is qualitative research, in which a documentary survey and semi-structured interview were carried out. Participated in the study, eleven elderly members of SUPERidade Project of the Secretaria de Assistência Social de Chapecó. For the analysis of information, the thematic content analysis technique was used, delimiting the category "Fear and Insecurity concerning barriers". Feelings of fear and insecurity constitute the social representations of the elderly about urban mobility, when they face barriers such as short time at traffic lights, the high step of public transportation, and disrespect on the part of vehicle drivers, whose interaction between barriers and functional limitations resulting from aging generate such feelings. Considering that aging is a progressive, irreversible, and predictable process in life, the urban space should be adapted to contribute to the inclusion of older adults with different degrees of functional capacity in the city's daily life. Eliminating the barriers means compensating for the functional limitations and promoting a fairer, more democratic, and healthier urban space.(AU)

@#Abstract: Objective　To analyze the epidemic characteristics of hand, foot and mouth disease (HFMD) in Nanping City, Fujian province and to provide the basis for formulating effective prevention and control measures as well as evaluating the efficacy of prevention and treatment. Methods　Descriptive epidemiological method was used to analyze the incidence data of HFMD in Nanping City from 2012 to 2021. Results　A total of 49 231 cases of HFMD were reported in Nanping City from 2012 to 2021. The incidence fluctuated greatly over the 10-year period, ranging from 76.10/100 000 to 308.93/100 000, with an average incidence of 184.99/100 000 per year. The overall incidence and the number of cases showed a fluctuating downward trend over time, but the incidence was high in the next year, and there were statistically significant differences in the incidence rates between different years(χ2=8 169.176, P<0.001). There were significant regional differences in the incidence, the top three average annual incidence rates were: Guanze County (370.76/100 000), Zhenghe County (295.31/100 000) and Wuyishan City (250.31/100 000). There were two peaks of HFMD incidence each year, with the first occurring in May and June and the second occurring in September and October. The incidence rate was higher among males (215.86/100 000) than females (152.93/100 000), and males were more susceptible than females (RR=1.412, 95%CI=1.387-1.438). The cases were mainly aged 0-4 years, accounting for 86.25% (42 461/49 231) of all cases, and the incidence rate gradually decreased with increasing age (χ2trend=570,105.801, P<0.001). The majority of cases (85.22%, 41 953/49 231) occurred in children living in scattered areas, followed by children in kindergartens (12.39%, 6 101/49 231). The etiological results showed a total of 3 476 laboratory-confirmed cases, and the proportion of three (classes) of enterovirus positivity varied each year, with different pathogen compositions showing statistical significance (χ2=584.613, P<0.001). In addition to the years 2015-2017, during which Cox A16 and EV71 were the dominant strains, other years were dominated by other enteroviruses, with EV71 being the main type in severe and fatal cases of HFMD in Nanping City. Conclusion　Nanping City should strengthen health education for children living in the diaspora and in day-care centers, enhance surveillance of epidemics and pathogenology, improve vaccination rates against EV71, focus on the detection and typing of other enteroviruses, and implement effective prevention and control measures for HFMD.

@#Abstract: Objective　To understand the situation of drug-resistant tuberculosis screening and epidemiological characteristics of multi-drug resistant tuberculosis (MDR-TB) and pre-extensively drug resistant tuberculosis (pre-XDR-TB) in Changsha, in order to provide a scientific basis for improving the quality of drug-resistant tuberculosis prevention and control in the city. Methods　Demographic information and drug susceptibility date of etiologically positive pulmonary tuberculosis patients in Changsha from 2018 to 2021 were collected, the successful rate of resistance screening, incidence and tendency in MDR-TB and pre-XDR-TB in patients included in this study were statistically analyzed accordingly. 　　Results From 2018 to 2021, the successful screening rates were 86.2%, 87.7%, 81.9% and 71.5% for MDR-TB and 82.2%, 84.8%, 76.9% and 68.2% for pre-XDR-TB, respectively. In each year, MDR-TB patients identified accounted for 7.6% (101/1 222), 6.5%(124/1 774), 6.6%(110/1 555) and 6.3%(99/1 478), and pre-XDR-TB patients identified accounted for 3.6%(46/1 219), 3.8%(69/1 766), 4.4%(69/1 495) and 4.6%(69/1 436), correspondingly. The incidence of MDR-TB showed a slowly downward trend, while the incidence of pre-MDR-TB showed a slowly upward trend, with neither decreasing nor increasing trends being statistically significant (（χ2=1.947，0.806，P>0.050). The incidence of MDR-TB in the retreatment failure population was 66.6% (2/3), and the others, failure initial treatment and recrudescence populations were 23.5% (19/81), 16.7% (2/12) and 15.2% (70/461), respectively. Similar to the incidence above, the incidence of pre-XDR-TB was 16.7% (2/12) among patients who failed in initial treatment, and 12.2% (9/74), 9.8% (43/439), and 4.5% (2/44) among the others, recrudescence and returned patients, respectively. The incidence rates of MDR-TB and pre-XDR-TB in different populations were significantly different (χ2=117.600，59.030，P<0.05). Conclusions There are still areas for improvement in tuberculosis drug resistance surveillance system in Changsha. On the premise of paying attention to patients in retreatment failure, other, initial treatment failure and relapse patients, high sensitivity molecular drug susceptibility testing, and scientifically efficient screening strategies must be explored.

@# or older during the outbreak epidemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant in Sanya City, Hainan Province, August-September 2022, and to provide scientific and effective basis for formulating strategies for the prevention and treatment of COVID-19 in the elderly in the future. Methods　The data of 1 785 COVID-19 cases aged ≥60 years reported from August 1 to September 8, 2022 in Sanya City, and 537 local COVID-19 inpatients aged ≥60 years treated in Sanya Central Hospital were collected and analyzed using WPS Office 2018 software for data cleaning, database assistance, and drawing, and SPSS 22.0 software was used to statistically describe and analyze the counting data. Results　A total of 1 785 local COVID-19 cases aged ≥60 years were reported in China's Disease Prevention and Control Information System, including 1 509 confirmed cases (84.54%) and 276 asymptomatic cases (15.46%). Of the confirmed cases, 1 448 were mild cases (95.96%), 40 were common cases (2.65%), 10 were severe cases (0.66%), and 11 were critical cases (0.73%), and no deaths were reported. The ratio of male to female was 0.88∶1. The youngest was 60 years old, the oldest age was 107 years old, with a median age of 67 years old. Most of them (1 559 cases, 87.34%) were non-social employed personnel. Among them, 952 (53.33%) were from Tianya District and 733 (41.06%) from Jiyang District. Among the 537 COVID-19 elderly infected patients hospitalized in Sanya Central Hospital, infected patients with underlying diseases accounted for 287 (53.45%) cases of hypertension, diabetes and other types of basic diseases (chronic kidney disease, hyperlipidemia, chronic gastritis, gastric ulcer, etc.), and there were serious infections. Conclusions　Most of the elderly infected with Omicron variants were mild cases with few symptoms, but the elderly infected with Omicron variants were difficult to recover or even worsen the condition due to old age and underlying diseases. Therefore, by analyzing the various aspects of elderly infected cases, scientific and effective basis can be provided to prevent and control the epidemic situation in the future, and reduce the occurrence of severe, critical and death cases of COVID-19 in the elderly.

Prevalence of parasitic infections in human stool samples from a hospital in Chenzhou City of Hunan Province / 中国血吸虫病防治杂志

Objective To investigate the prevalence of parasitic infections in human stool samples from a hospital in Chenzhou City, Hunan Province, so as to provide insights into the management of intestinal parasitic diseases. Methods Stool samples were collected from patients admitted to a hospital in Chenzhou City from September 2020 to March 2021, subjected to physiological saline smearing and microscopy for detection of intestinal parasites. The prevalence of parasitic infections and the species of parasites were descriptively analyzed. Results The overall prevalence of intestinal parasitic infections was 1.61% in the 10 728 stool samples, and there were 3 samples with mixed infections of two parasite species. A total of seven parasite species were identified, including Blastocystis hominis (162 cases, 1.55%), Giardia lamblia (5 cases, 0.05%), Dientamoeba fragilis (5 cases, 0.05%), Endolimax nana (one case, 0.01%), Iodamoeba bütschlii (one case, 0.01%), Strongyloides stercoralis (one case, 0.01%) and Trichomonas hominis (one case, 0.01%). The prevalence of intestinal parasitic infection was significantly higher among women than in men (2.14% vs. 1.25%; χ2 = 13.01, P < 0.01), and a high prevalence rate was seen among patients at ages of 20 to 30 years (2.99%) and 80 years and older (2.86%); however, no age-specific prevalence of intestinal parasitic infection was detected (χ2 = 12.45, P > 0.05). Conclusions The overall prevalence of intestinal parasitic infection was low among patients admitted to a hospital in Chenzhou City, and gender-specific prevalence was found. Food-borne and opportunistic parasites were predominant intestinal parasites, including B. hominis, G. lamblia and D. fragilis.

Objective To investigate the prevalence and influencing factors of soil-transmitted nematode infections in Ningbo City from 2016 to 2021, so as to provide insights into the development of targeted control measures against soil-transmitted nematodiasis. Methods Permanent residents at ages of 3 years and older were sampled in Ningbo City using a multi-stage sampling method each year during the period from 2016 to 2021. Soil-transmitted nematode eggs were detected in stool samples using a modified Kato-Katz thick smear method (two slides for each stool sample), and Enterobius vermicularis eggs were additionally identified among children at ages of 3 to 12 years using the adhesive cellophane-tape perianal swab method. The time- and regions-specific prevalence of soil-transmitted nematode infections was calculated, and the factors affecting hookworm infections were identified using a multivariate logistic regression model. Results A total of 11 573 person-times were detected for soil-transmitted nematode infections in Ningbo City from 2016 to 2021, and 296 egg-positives were detected, with a mean prevalence rate of 2.56% [95% confidential interval (CI): (2.28%, 2.87%)]. Hookworm was the predominant species of soil-transmitted nematode among egg-positives in Ningbo City (98.31%, 291/296), and there was a significant difference in the prevalence of hook-worm infections among years (χ2 = 190.27, P < 0.01). The highest prevalence of hook-worm infections was observed in Ninghai County (4.06%), and there was a region-specific prevalence rate of hookworm infection in Ningbo City (χ2 = 148.43, P < 0.01). Multivariate logistic regression analysis showed that elderly residents at ages of over 60 years [odds ratio (OR)= 1.94, 95% CI: (1.07, 3.54), P < 0.05], males [OR = 2.19, 95% CI: (1.72, 2.80), P < 0.01], farmers [OR = 6.94, 95% CI: (3.37, 14.29), P < 0.01] and residents with a low education level [illiteracy or semi-illiterate: OR = 3.82, 95% CI: (1.56, 9.35), P < 0.05; primary school: OR = 2.70, 95% CI: (1.11, 6.59), P < 0.05] were at a higher risk for hookworm infections. Conclusions The overall prevalence of soil-transmitted nematode infections was low among residents in Ningbo City from 2016 to 2021. The surveillance and health education for human hookworm disease remain to be reinforced among male farmers with a low education level at ages of over 60 years in Ninghai County.

Objective To investigate the prevalence of Angiostrongylus cantonensis infection in market-sold and field-captured snails in Fujian Province, so as to provide the scientific basis for the formulation of the angiostrongyliasis control measures. Methods In each month from May to October during the period from 2017 through 2021, Pomacea snails were collected from two field fixed surveillance sites and Bellamya aeruginosa collected from one agricultural product market in Fuzhou City, while Pomacea and B. aeruginosa snails were collected from two agricultural product markets and four restaurants in Xiamen City. At least 50 Pomacea snails and 500 g B. aeruginosa were sampled each time. A. cantonensis infection was detected in Pomacea snails using lung microscopy, and in B. aeruginosa using a tissue homogenate method. Results A total of 9 531 Pomacea snails were detected for A. cantonensis infection in two cities of Fuzhou and Xiamen, and the overall prevalence of A. cantonensis infection was 4.40%, with the highest prevalence in 2017 (6.82%, 116/1 701) and the lowest prevalence in 2019 (3.46%, 83/2 400). The prevalence of A. cantonensis infection was significantly higher in Pomacea snails sampled from Fuzhou City (11.23%, 326/2 903) than from Xiamen City (1.40%, 93/6 628) (χ2 = 461.48, P < 0.01). A. cantonensis larvae were detected in larval Pomacea snails in two cities of Fuzhou and Xiamen each month. The prevalence of A. cantonensis infection in Pomacea snails appeared an overall tendency towards a rise with month in Fuzhou City, with the highest prevalence in October (15.24%), and there was a significant difference among month (χ2 = 14.56, P < 0.05), while the prevalence of A. cantonensis infection in Pomacea snails was low in Pomacea snails sampled from Xiamen City each month, with the highest prevalence in June (2.64%), and there was a significant difference among month (χ2 = 23.17, P < 0.05). A total of 18 966 B. aeruginosa snails were detected for A. cantonensis infection in two cities of Fuzhou and Xiamen, and the overall prevalence of A. cantonensis infection was 0.01%. Conclusions A. cantonensis infection was identified in Pomacea and B. aeruginosa snails in Fujian Province from 2017 to 2021, and there is a potential risk of human A. cantonensis infection.

ObjectiveTo monitor the microbes in urban drinking water in Jiangxi from 2016 to 2020， to analyze the change in microbial qualification rate， and to provide a scientific basis for government decision-making. MethodsAccording to the Standard Examination Method for Drinking Water （GB/T 5750‒2006） and the Standards for Drinking Water Quality （GB 5749‒2006）， the water samples were collected， tested and evaluated for hygienic safety. The chi-square test was used to compare the qualification rates among different water periods， water source types， water supply modes， water samples， treatment processes， and disinfection methods. ResultsA total of 10 584 water samples were collected and examined from 2016 to 2020，with a qualification rate of 97.72%. The qualified rate of the microbiological index increased gradually over the years. There was no statistically significant difference in the microbiological qualification rate of water samples monitored in different water periods （χ2=0.718，P=0.398）， and the qualification rates were 97.85% and 97.60% in dry and abundant water periods respectively. There was a statistically significant difference in the qualification rates of water samples monitored in different water source types （χ2=79.560，P=0.398）， with groundwater having a higher qualification rate of 98.83% than surface water （97.70%）. The microbiological pass rate of water samples differed among different water supply methods （χ2=201.836，P<0.001）. The microbiological pass rates of municipal centralized water supply， self-built centralized water supply and secondary water supply were 97.51%， 88.94% and 96.56% respectively. The microbiological pass rates of water samples differed among different treatment processes. There were differences in the qualification rates of the water samples between different treatment processes（χ2=855.034，P<0.001）， with 98.22%， 67.19%， 95.60% and 53.13% of the conventionally treated， precipitated filtered， disinfected only and untreated water samples， respectively. The differences in the microbiological qualification rates of the monitored water samples between different disinfection methods were statistically significant （χ2=904.993，P<0.001）. Chlorination disinfection， chlorine dioxide disinfection， other disinfection methods and non-disinfected water samples had the pass rates of 98.35%， 98.19%， 84.38% and 60.16%， respectively. ConclusionThe qualified rate of the microbiological index of drinking water in Jiangxi increases year by year， but there are still some drinking water without appropriate disinfectants and water quality treatment processes. There is still a need to strengthen the purification， disinfection and monitoring of drinking water.

Objective@#To investigate the trends in mortality of malignant tumors in Ningbo City, Zhejiang Province from 2002 to 2022, so as to provide the evidence for formulating malignant tumor control strategies in Ningbo City. Methods The data regarding the mortality of malignant tumors in Ningbo City from 2002 to 2022 were collected through the Ningbo Municipal Death Cause Monitoring System, and the crude mortality and age-specific mortality of malignant tumors were calculated in Ningbo City. The mortality of malignant tumors was standardized by the population of the sixth National Population Census in China in 2010 (Chinese-standardized mortality) and the world standard population in 1960 (world-standardized mortality). The trends in mortality of malignant tumors were evaluated with annual percent change (APC) and average annual percent change (AAPC). @*Methods@#The data regarding the mortality of malignant tumors in Ningbo City from 2002 to 2022 were collected through the Ningbo Municipal Death Cause Monitoring System, and the crude mortality and age-specific mortality of malignant tumors were calculated in Ningbo City. The mortality of malignant tumors was standardized by the population of the sixth National Population Census in China in 2010 (Chinese-standardized mortality) and the world standard population in 1960 (world-standardized mortality). The trends in mortality of malignant tumors were evaluated with annual percent change (APC) and average annual percent change (AAPC). @*Results@#The crude mortality of malignant tumors was 186.43/105 to 221.24/105 in Ningbo City from 2002 to 2022, which showed a tendency towards a rise (AAPC=0.76%), and both the Chinese- (AAPC=-2.64%) and world-standardized mortality (AAPC=-2.74%) appeared a tendency towards a decline (all P<0.05). The world-standardized mortality of malignant tumors presented three changes in Ningbo City from 2002 to 2022, with a more remarkable decline from 2011 to 2018 (APC=-3.53%) than from 2002 to 2011 (APC=-2.10%) and from 2018 to 2022 (APC=-2.00%) (all P<0.05). The annual decline in mortality of malignant tumors was higher in men (Chinese-standardized mortality: AAPC=-2.68%; world-standardized mortality: AAPC=-2.75%) than in women (Chinese-standardized mortality: AAPC=-2.45%; world-standardized mortality: AAPC=-2.57%), and higher in urban areas (Chinese-standardized mortality: AAPC=-2.85%; world-standardized mortality: AAPC=-2.92%) than in rural areas (Chinese-standardized mortality: AAPC=-2.45%; world-standardized mortality: AAPC=-2.57%) (all P<0.05). The mortality of malignant tumors appeared a tendency towards a rise with age in Ningbo City, with the highest mortality in residents at ages of 85 years and older (1 447.13/105). Death from malignant tumors were responsible for 31.86% of all causes of death in Ningbo City, and the five most common causes of cancer death included lung cancer, liver cancer, gastric cancer, colorectal cancer and esophageal cancer. In addition, the world-standardized mortality of pancreatic cancer (AAPC=3.92%), prostate cancer (AAPC=4.71%), and cervical cancer (AAPC=1.60%) appeared a tendency towards a rise in Ningbo City (all P<0.05). @*Conclusions@#The crude mortality of malignant tumors appeared a tendency towards a rise in Ningbo City from 2002 to 2022, while the standardized mortality showed a tendency towards a decline. Management of malignant tumors should be given a high priority among men and rural residents, and lung cancer, liver cancer, gastric cancer, colorectal cancer and esophageal cancer should be emphasized.
