Whether in the form of visible garbage or microparticles, as it slowly degrades, plastic pollution poses significant threats to terrestrial and aquatic habitats and the wildlife that call them home, whether through ingestion, entanglement or exposure to the chemicals contained in the material. Unfortunately, there is a lack of documentation on the impact of plastic waste on human health in low- and middle-income countries (LMICs). Methods: We searched five electronic databases (PubMed, Embase, Global Health, CINAHL and Web of Science) and gray literature, following the preferred reporting elements for systematic reviews and meta-analyses (PRISMA), for the impact of plastic waste on human health in developing countries. We included quantitative and qualitative studies written in English and French. We assessed the quality of the included articles using the Mixed Methods Appraisal tool (MMAT). Results: A total of 3779 articles were initially identified by searching electronic databases. After eliminating duplicates, 3167 articles were reviewed based on title and abstract, and 26 were selected for full-text review. Only three articles were retained. The three articles dealt with practices likely to lead to oral exposure to plastic chemicals in human health, as well as the level of awareness of participants concerning the possible impact of plastic on human health, namely, the use of plastic baby bottles, the use of microwaves to cook food and reheat precooked food, the use of plastic bottles to store water in the refrigerator, water purifier containers with plastic bodies and plastic lunch boxes, the reuse of plastic bags and the inadequacy of treatment facilities. Conclusion: Plastic waste poses different risks to human health at every stage of its life cycle. Hence, strategies must be adopted to raise public awareness of the dangers of plastic waste to their health. Trial registration: The review protocol is registered in the PROSPERO international prospective register of systematic reviews (ID = CRD42023409087).展开更多

Based on the resident population statistics data of Henan province from 2006 to 2021, with county as the basic study unit, the paper studies the spatial morphology characteristics and its evolution patterns of resident population distribution, by using spatial analysis methods such as population distribution center, standard deviation ellipse, and spatial auto correlation analysis. The results show that: the resident population spatial distribution shows unbalanced state, the population agglomeration areas mainly distribute in the northeast part and north part, where the resident population growth rate is significantly higher than other regions, over time, this trend is gradually becoming significant. The resident population distribution has a trend of centripetal concentration, with the degree and trend of centripetal gradually strengthening. The resident population distribution has obvious directional characteristics, but the significance is not high, the weighted resident population average center is approximately located at (4.13740˚N, 113.8935˚E), and the azimuth of the distribution axis is approximately 11.19˚. The population distribution has obvious agglomeration characteristics, with the built-up areas of Zhengzhou and Luoyang as their centers, where have a significant siphon effect on the surrounding population. The southern and southwestern regions in the province form a relatively stable belt area of Low-Low agglomeration areas.展开更多

However, the COVID-19 pandemic has influenced population health worldwide. This study aimed to examine disparities in population health and health-related factors between rural and urban communities during the COVID-19 pandemic. A literature search was conducted using PubMed, Medline, and CINAHL for articles published up to September 2022 with the following search terms: community health, rural, urban, and COVID-19. A total of 105 articles were identified, of which three articles with a cross-sectional quantitative research design met the inclusion criteria. Two articles focused on mental health, and among them, one recognized a significant disparity between rural and urban areas. Four health-related factors in view of the COVID-19 pandemic in rural and urban areas were perceived, including knowledge, behavior, lifestyle, and social support. And, two factors: health-related knowledge and health-related behavior, were perceived as the significant disparities between rural and urban during the COVID-19 pandemic. The further efforts will be needed to pursue effective integrated community-based care system during and post-COVID-19, taking into account community environment at both community and individual levels.展开更多

Solid dust particles and SO2, which are the main polluting substances in coal mining and burning, are the main causes of diseases in areas with intensive coal mining. This contribution deals with areas in the Czech Republic which have the greatest problems in this regard, being North Bohemia (Chomutov, Most, Teplice and ústí nad Labem districts). It is an area with considerable anthropogenic activity, mainly due to the intensive mining of brown coal, which has a direct effect on the health of the inhabitants of the entire ústí nad Labem region. Along with the growing number of inhabitants, energy consumption demands are constantly increasing. Nevertheless, it’s important to focus primarily on renewable energy sources, which will ensure the sustainable development of the environment and society. At the same time, the question arises, which energy sources can potentially be utilized here after mining ends (2052). In terms of geography, wind energy has the greatest potential in this area. This and associated issues are dealt with by the project “Sustainable Forms of Management in an Anthropogenically Burdened Region” at the Faculty of Environment at the University of Jan E. Purkyně in ústí nad Labem.展开更多

The results showed that the serum lysozyme (S-LZM) activities in Group 3 (adult inhabitants exposed to 0.20 mg/m3 VC for at least 8 years), Group 2 (workers exposed to 4.1 mg/m3for at least 7 years occupationally), Group 1 (workers exposed to 25.7 mg/m3 for at least 2 years) were significantly higher than control. G-banding CA analysis showed that the total chromosome breakage rates in both Groups 1 and 2 were higher, but no difference existed between Group 3 and control. Only Group 1 was observed having higher SCEs, CA level and lower TcTR than control. AKP levels in Groups 1 and 2 were higher than control,but noγ-GT and GPT differences were found among groups. The study also suggests that G-banding CA analysis is more sensitive than CA and SCEs展开更多

However, opposite trends are seen among key populations (KP). The HIV prevalence among sex workers is as high as 51% and continues to rise. While the HIV prevalence among KP remains high, their adherence to treatment is low. Healthcare providers play a vital role in KP’s access and adherence to HIV treatment. This study aimed to explore the perspectives of healthcare providers on providing HIV services to key populations in Rwanda. Methods: An exploratory qualitative study was conducted with nurses, doctors, social workers, and psychologists who provide HIV services to KP in public health facilities in Rwanda. In-depth interviews were conducted using a semi-structured interview guide. All data were analyzed thematically using Dedoose. Results: Interviews were conducted with 18 healthcare providers. Three overarching themes emerged from the interviews: healthcare providers’ intrinsic feelings affect the ways they provide HIV services to key populations, key populations face a multitude of challenges related to accessing treatment and preventing the spread of HIV, and a more comprehensive and sensitive approach should be used to improve HIV services for key populations. Conclusion: Healthcare providers expressed difficulties in providing services to key populations and identified a lack of adherence to treatment and prevention guidelines, structural barriers, KP’s lack of trust in the healthcare system, and the discrimination and abuse KP face as challenges to effective HIV prevention and treatment. More comprehensive services including clinical, financial, and psychosocial support from trusted sources are needed. Some important policy changes are essential to facilitate access to HIV services for KP.展开更多

A total of 400 counties were randomly sampled. ANOVA and Logistic regression modeling were employed to estimate differ- ences in health outcomes and determinants. Significant differences were found between the western, central and eastern rural regions in community infrastructure and health outcomes. From 2000 to 2010, health indicators in rural China were improved significantly, and the infant mortality rate (IMR), mater- nal mortality rate (MMR) and under 5 mortality rate (U5MR) had fallen by 62.79%, 71.74% and 61.92%, respectively. Central rural China had the greatest decrease in IMR (65.05%); whereas, western rural China had the greatest reduction in MMR (72.99%) but smallest reduction in U5MR (57.36%). Despite these improvements, Logistic regression analysis showed regional differences in key health outcome indicators (odds ratios): IMR (central: 2.13; western: 5.31), U5MR (central: 2.25; western: 5.69), MMR (central: 1.94; western: 3.31), and prevalence of infectious diseases (central: 1.62; western: 3.58). The community infrastructure and health outcomes of the western and central rural regions of China have been improved markedly during the first decade of the 21st century. However, health dis- parities still exist across the three regions. National efforts to increase per capita income, community empowerment and mobilization, community infrastructure, capacity of rural health facilities, and health literacy would be effective policy options to attain health equity.展开更多

This is due to (1) The rapid and widespread adoption of powerful contemporary Smartphone’s;(2) The increasing availability and use of health and fitness sensors, wearable sensor patches, smart watches, wireless-enabled digital tattoos and ambient sensors;and (3) The nature of public health to implicitly involve connectivity with and the acquisition of data in relation to large numbers of individuals up to population scale. Of particular relevance in relation to the Internet of Things (IoT) and public health is the need for privacy and anonymity of users. It should be noted that IoT capabilities are not inconsistent with maintaining privacy, due to the focus of public health on aggregate data not individual data and broad public health interventions. In addition, public health information systems utilizing IoT capabilities can be constructed to specifically ensure privacy, security and anonymity, as has been developed and evaluated in this work. In this paper we describe the particular characteristics of the IoT that can play a role in enabling emerging public health capabilities;we describe a privacy-preserving IoT-based public health information system architecture;and provide a privacy evaluation.展开更多

In addition to identifying potential access to safe drinking water during climate change and potential health hurdles brought on by water-related diseases, it is important to learn how to reduce the spread of water-borne diseases. Methods: A mixed method design was adopted to evaluate this research, and probability sampling, more specifically simple random sampling, was used to select to sample from the target population. The study was conducted in Taltali upazila of the Barguna district, and data was collected from 384 respondents;among them, 5 respondents were selected for the key informant interview. The research project began in June 2022 and was completed in December 2022. Results: 41.4% of respondents said they suffer from dysentery, 22.4% said the expense of treating water-borne diseases has increased as a result of climate change, and 37.8% said they must travel great distances to obtain clean drinking water. Currently, 41.7% of individuals utilize tube-well water, compared to 19.3% five to ten years ago, and 27.4% have been taught that water filtration helps reduce the spread of water-borne diseases. Conclusions: People’s vulnerability to climate change in the study area is a result of factors such as rapid population increase, unequal access to resources, food insecurity, a long distance to collect water, inadequate medical facilities, a lack of poverty, and a weak health system.展开更多

文摘Background: Plastic pollution is the accumulation of waste composed of plastic and its derivatives all over the environment. Whether in the form of visible garbage or microparticles, as it slowly degrades, plastic pollution poses significant threats to terrestrial and aquatic habitats and the wildlife that call them home, whether through ingestion, entanglement or exposure to the chemicals contained in the material. Unfortunately, there is a lack of documentation on the impact of plastic waste on human health in low- and middle-income countries (LMICs). Methods: We searched five electronic databases (PubMed, Embase, Global Health, CINAHL and Web of Science) and gray literature, following the preferred reporting elements for systematic reviews and meta-analyses (PRISMA), for the impact of plastic waste on human health in developing countries. We included quantitative and qualitative studies written in English and French. We assessed the quality of the included articles using the Mixed Methods Appraisal tool (MMAT). Results: A total of 3779 articles were initially identified by searching electronic databases. After eliminating duplicates, 3167 articles were reviewed based on title and abstract, and 26 were selected for full-text review. Only three articles were retained. The three articles dealt with practices likely to lead to oral exposure to plastic chemicals in human health, as well as the level of awareness of participants concerning the possible impact of plastic on human health, namely, the use of plastic baby bottles, the use of microwaves to cook food and reheat precooked food, the use of plastic bottles to store water in the refrigerator, water purifier containers with plastic bodies and plastic lunch boxes, the reuse of plastic bags and the inadequacy of treatment facilities. Conclusion: Plastic waste poses different risks to human health at every stage of its life cycle. Hence, strategies must be adopted to raise public awareness of the dangers of plastic waste to their health.

文摘Coal mining has proven negative impacts on the landscape and health of inhabitants. Solid dust particles and SO2, which are the main polluting substances in coal mining and burning, are the main causes of diseases in areas with intensive coal mining. This contribution deals with areas in the Czech Republic which have the greatest problems in this regard, being North Bohemia (Chomutov, Most, Teplice and ústí nad Labem districts). It is an area with considerable anthropogenic activity, mainly due to the intensive mining of brown coal, which has a direct effect on the health of the inhabitants of the entire ústí nad Labem region. Along with the growing number of inhabitants, energy consumption demands are constantly increasing. Nevertheless, it’s important to focus primarily on renewable energy sources, which will ensure the sustainable development of the environment and society. At the same time, the question arises, which energy sources can potentially be utilized here after mining ends (2052). In terms of geography, wind energy has the greatest potential in this area. This and associated issues are dealt with by the project “Sustainable Forms of Management in an Anthropogenically Burdened Region” at the Faculty of Environment at the University of Jan E. Purkyně in ústí nad Labem.
文摘A series of indicators, including serum lysozyme activity, G-banding chromosome aberration (G-banding CA) analysis, sister chromatid exchanges (SCEs), chromosome aberration (CA), T-lymphocyte transformation rate (TcTR),-GT, GPT and AKP, were employed in the present survey among occupationally vinyl chloride (VC) exposed workers and inhabitants living in VC polluted area in a polyvinyl chloride (PVC) factory. The results showed that the serum lysozyme (S-LZM) activities in Group 3 (adult inhabitants exposed to 0.20 mg/m3 VC for at least 8 years), Group 2 (workers exposed to 4.1 mg/m3for at least 7 years occupationally), Group 1 (workers exposed to 25.7 mg/m3 for at least 2 years) were significantly higher than control. G-banding CA analysis showed that the total chromosome breakage rates in both Groups 1 and 2 were higher, but no difference existed between Group 3 and control. Only Group 1 was observed having higher SCEs, CA level and lower TcTR than control. AKP levels in Groups 1 and 2 were higher than control,but noγ-GT and GPT differences were found among groups. The study also suggests that G-banding CA analysis is more sensitive than CA and SCEs
文摘Background: The overall HIV prevalence and incidence in Rwanda have decreased significantly in the past decade. However, opposite trends are seen among key populations (KP). The HIV prevalence among sex workers is as high as 51% and continues to rise. While the HIV prevalence among KP remains high, their adherence to treatment is low. Healthcare providers play a vital role in KP’s access and adherence to HIV treatment. This study aimed to explore the perspectives of healthcare providers on providing HIV services to key populations in Rwanda. Methods: An exploratory qualitative study was conducted with nurses, doctors, social workers, and psychologists who provide HIV services to KP in public health facilities in Rwanda. In-depth interviews were conducted using a semi-structured interview guide. All data were analyzed thematically using Dedoose. Results: Interviews were conducted with 18 healthcare providers. Three overarching themes emerged from the interviews: healthcare providers’ intrinsic feelings affect the ways they provide HIV services to key populations, key populations face a multitude of challenges related to accessing treatment and preventing the spread of HIV, and a more comprehensive and sensitive approach should be used to improve HIV services for key populations. Conclusion: Healthcare providers expressed difficulties in providing services to key populations and identified a lack of adherence to treatment and prevention guidelines, structural barriers, KP’s lack of trust in the healthcare system, and the discrimination and abuse KP face as challenges to effective HIV prevention and treatment. More comprehensive services including clinical, financial, and psychosocial support from trusted sources are needed. Some important policy changes are essential to facilitate access to HIV services for KP.

文摘Summary: Health disparities between the western, central and eastern regions of rural China, and the impact of national health improvement policies and programming were assessed. A total of 400 counties were randomly sampled. ANOVA and Logistic regression modeling were employed to estimate differ- ences in health outcomes and determinants. Significant differences were found between the western, central and eastern rural regions in community infrastructure and health outcomes. From 2000 to 2010, health indicators in rural China were improved significantly, and the infant mortality rate (IMR), mater- nal mortality rate (MMR) and under 5 mortality rate (U5MR) had fallen by 62.79%, 71.74% and 61.92%, respectively. Central rural China had the greatest decrease in IMR (65.05%); whereas, western rural China had the greatest reduction in MMR (72.99%) but smallest reduction in U5MR (57.36%). Despite these improvements, Logistic regression analysis showed regional differences in key health outcome indicators (odds ratios): IMR (central: 2.13; western: 5.31), U5MR (central: 2.25; western: 5.69), MMR (central: 1.94; western: 3.31), and prevalence of infectious diseases (central: 1.62; western: 3.58). The community infrastructure and health outcomes of the western and central rural regions of China have been improved markedly during the first decade of the 21st century. However, health dis- parities still exist across the three regions. National efforts to increase per capita income, community empowerment and mobilization, community infrastructure, capacity of rural health facilities, and health literacy would be effective policy options to attain health equity.

文摘To achieve awareness of the initiative practice for health concept in the Chinese population,traditional Chinese medicine(TCM)doctors should popularize TCM culture and knowledge among young people,people with a low level of education,in low-income populations,and in rural populations.
文摘The Internet of things has particularly novel implications in the area of public health. This is due to (1) The rapid and widespread adoption of powerful contemporary Smartphone’s;(2) The increasing availability and use of health and fitness sensors, wearable sensor patches, smart watches, wireless-enabled digital tattoos and ambient sensors;and (3) The nature of public health to implicitly involve connectivity with and the acquisition of data in relation to large numbers of individuals up to population scale. Of particular relevance in relation to the Internet of Things (IoT) and public health is the need for privacy and anonymity of users. It should be noted that IoT capabilities are not inconsistent with maintaining privacy, due to the focus of public health on aggregate data not individual data and broad public health interventions. In addition, public health information systems utilizing IoT capabilities can be constructed to specifically ensure privacy, security and anonymity, as has been developed and evaluated in this work. In this paper we describe the particular characteristics of the IoT that can play a role in enabling emerging public health capabilities;we describe a privacy-preserving IoT-based public health information system architecture;and provide a privacy evaluation.

文摘Falling is among the most harmful events older adults may encounter.With the continuous growth of the aging population in many societies,developing effective fall detection mechanisms empowered by machine learning technologies and easily integrable with existing healthcare systems becomes essential.This paper presents a new healthcare Internet of Health Things(IoHT)architecture built around an ensemble machine learning-based fall detection system(FDS)for older people.Compared to deep neural networks,the ensemble multi-stage random forest model allows the extraction of an optimal subset of fall detection features with minimal hyperparameters.The number of cascaded random forest stages is automatically optimized.This study uses a public dataset of fall detection samples called SmartFall to validate the developed fall detection system.The SmartFall dataset is collected based on the acquired measurements of the three-axis accelerometer in a smartwatch.Each scenario in this dataset is classified and labeled as a fall or a non-fall.In comparison to the three machine learning models—K-nearest neighbors(KNN),decision tree(DT),and standard random forest(SRF),the proposed ensemble classifier outperformed the other models and achieved 98.4%accuracy.The developed healthcare IoHT framework can be realized for detecting fall accidents of older people by taking security and privacy concerns into account in future work.
文摘Objectives: To determine the economic challenges brought on by water-borne illnesses as a result of climate change. In addition to identifying potential access to safe drinking water during climate change and potential health hurdles brought on by water-related diseases, it is important to learn how to reduce the spread of water-borne diseases. Methods: A mixed method design was adopted to evaluate this research, and probability sampling, more specifically simple random sampling, was used to select to sample from the target population. The study was conducted in Taltali upazila of the Barguna district, and data was collected from 384 respondents;among them, 5 respondents were selected for the key informant interview. The research project began in June 2022 and was completed in December 2022. Results: 41.4% of respondents said they suffer from dysentery, 22.4% said the expense of treating water-borne diseases has increased as a result of climate change, and 37.8% said they must travel great distances to obtain clean drinking water. Currently, 41.7% of individuals utilize tube-well water, compared to 19.3% five to ten years ago, and 27.4% have been taught that water filtration helps reduce the spread of water-borne diseases. Conclusions: People’s vulnerability to climate change in the study area is a result of factors such as rapid population increase, unequal access to resources, food insecurity, a long distance to collect water, inadequate medical facilities, a lack of poverty, and a weak health system.
