We analyzed the source apportionment and assessed the health risk of TMs in agricultural soils by using positive matrix factorization(PMF) model and health risk assessment(HRA) model based on Monte Carlo simulation. Meanwhile, we combined PMF and HRA models to explore the health risks of TMs in agricultural soils by different pollution sources to determine the priority control factors. Results showed that the average contents of cadmium(Cd), arsenic (As), lead(Pb), chromium(Cr), copper(Cu), nickel(Ni), and zinc(Zn) in the soil were found to be 0.26, 5.93, 27.14, 61.32, 23.81, 32.45, and 78.65 mg/kg, respectively. Spatial analysis and source apportionment analysis revealed that urban and industrial sources, agricultural sources, and natural sources accounted for 33.0%, 27.7%, and 39.3% of TM accumulation in the soil, respectively. In the HRA model based on Monte Carlo simulation, noncarcinogenic risks were deemed negligible(hazard index <1), the carcinogenic risks were at acceptable level(10^(-6)<total carcinogenic risk ≤ 10^(-4)), with higher risks observed for children compared to adults. The relationship between TMs, their sources, and health risks indicated that urban and industrial sources were primarily associated with As, contributing to 75.1% of carcinogenic risks and 55.7% of non-carcinogenic risks, making them the primary control factors. Meanwhile, agricultural sources were primarily linked to Cd and Pb, contributing to 13.1% of carcinogenic risks and 21.8% of non-carcinogenic risks, designating them as secondary control factors.展开更多

However, whether the parent-child activities and using digital devices were serial mediators of the relationship between children’s health and social development needs further verification. Purpose: This study explored how parent-child activities and children’s use of digital devices influence the relationship between children’s health and their social competence. Method: This study used data from Kids in Taiwan: National Longitudinal Study of Child Development and Care. A total sample of 2164 participants was used in this study. Serial mediation analyses were performed using model six of Hayes’ PROCESS (2012). Results: This study found that parent-child activities and the use of digital devices can serially mediate the relationship between children’s health and social competence. Children’s health could directly improve their social competence, but it could also serially mediate social competence by increasing parent-child activities and reducing the use of digital devices. Conclusion: Childcare policy planners and parenting educators should not only call on parents to reduce the use of electronic products for their children, but also encourage parents to spend more time interacting with their children, so that children can learn social skills by interacting with others in their daily lives.展开更多

This study aimed to assess the knowledge and practices, in terms of pig biosecurity measures, of individual stakeholders involved in pig production in rural and peri-urban households in Cambodia. A survey tool was developed and administered using Kobotoolbox, an online electronic survey tool. Surveys were conducted in the provinces of Kampong Thom, Siem Reap, and Battambang during December 2017 to September 2018. There were 225 pig farmers, 43 village animal health workers (VAHWs), 3-district veterinarians (DVs), and 81 feed store owners enrolled in the study. Results showed that several biosecurity guidelines are not followed or well understood by farmers. Specific concerning practices included using natural boars, sharing pig equipment (e.g. scales), feeding kitchen waste, managing other livestock, handling manure, and not restricting access by visitors (VAHWs or DVs, boar owners, pig buyers, neighbors, and meat sellers). Thus, education of pig smallholder farmers and VAHWs on pig biosecurity is needed for improving pig health and production, economic value, and livelihood of smallholder farmers in Cambodia.展开更多

This study aims to interpret how these environmental factors influence the age of onset, severity of symptoms such as hot flushes and night sweats, and other long-term effects of menopause. Understanding these relationships addresses a significant gap in current knowledge and could guide future public health strategies. Methods: Through a comprehensive analysis of three cross-continental studies involving 1500 postmenopausal women from Spain, South American countries (Ecuador, Panama, Chile), various climates in Türkiye (Black Sea, Mediterranean, Continental), and the United Arab Emirates (UAE), this review evaluates diverse environmental impacts. Studies were selected based on their methodological rigor, geographical diversity, and focus on the unique and personal experiences of menopause. Data was collected via questionnaires and routine medical checkups, analyzing demographic, lifestyle, mood, symptom severity, and onset age variables. Results: Preliminary analysis indicates that 52.5% of participants from Spanish-speaking countries and the UAE reported vasomotor symptoms, with those in higher temperatures and lower altitudes experiencing exacerbated symptoms. Notably, Mediterranean climates were associated with an earlier menopause onset. Seasonal changes had minimal impact across all regions, suggesting lifestyle and other environmental factors play a more significant role. Conclusions: The findings highlight a clear link between climate-related geographical factors and the menopausal experience. Women in warmer, lower-altitude regions suffer more severe symptoms, while those in Mediterranean climates face earlier onset. The absence of significant seasonal variations across the studies underscores the predominance of lifestyle and environmental factors over purely climatic conditions. These insights pave the way for targeted interventions and support the need for further public health research into the complex interactions between climate change and menopause.展开更多

Structured searches were performed in Pub Med,MEDLINE,EMBASE,Web of Science and Cochrane Library from January 1976 to June 2016 using the following keywords:(inflammatory bowel disease OR Crohn's disease OR ulcerative colitis) AND(health maintenance OR preventive health OR health promotion). Abstracts of the articles selected from each of these multiple searches were reviewed,and those meeting the inclusion criteria(that is,providing data regarding preventive health or health maintenance in IBD patients) were recorded. Reference lists from the selected articles were manually reviewed to identify further relevant studies. Patients with IBD are at increased risk of developing adverse events related to the disease course,therapeutic interventions,or non-adherence to medication. Recent studies have suggested that IBD patients do not receive preventive services with the same thoroughness as patients with other chronic diseases. Preventive health measures can avert morbidity and improve the quality of life of patients with IBD. Gastroenterologists and primary care physicians(PCPs) should have an up to date working knowledge of preventive health measures for IBD patients. A holistic approach and better communication between gastroenterologists and PCPs with explicit clarification of roles will prevent duplication of services and streamline care.展开更多

Menopausal women using HRT for the relief of vasomotor symptoms were advised to use the lowest possible dose of HRT over the shortest possible duration. Objective: This study sought to examine patterns of HRT use for the treatment of menopausal symptoms before and after the WHI among women at least 40 years of age. Methods: A retrospective analysis was performed on a total of 1367 women in the pre-WHI group and 6467 women in the post-WHI group using the U.S. General Electric (GE) Centricity electronic medical record database. Menopause diagnosis was assessed using ICD-9 codes. Clinical characteristics and medication use were assessed for women with at least 3 years of enrollment (1 year baseline, 2 years follow-up). Results: The proportion of women in the post-WHI group that initiated HRT was significantly less than that of women in the pre-WHI group (31.3% vs. 56.9%, respectively;p < 0.001). Combination HRT use declined significantly (21.9% pre-WHI cohort vs. 7.2% post- WHI cohort, p < 0.001) among increases in non-HRT use, namely SSRIs (15.2% pre-WHI cohort v. 22.3% post-WHI cohort, p < 0.001) and tranquilizers (9.5% pre-WHI cohort v. 15.8% post-WHI cohort, p < 0.001). Conclusion: The results of the WHI 2002 publication made an impression on the perception of HRT’s role in the relief of menopausal symptoms. Decision-making on the part of women seeking treatment for vasomotor symptoms and women’s health professionals demonstrates that despite HRT precautions, women continue to exhibit a need for HRT use. This study’s findings suggest that women seeking treatment for menopausal symptom relief and women’s health professionals continue to work together to find the appropriate balance between therapy use and adherence to therapy use guidelines.展开更多

文摘Objective: This systematic review investigates the impact of climate change on menopause, focusing on the correlation between geographical location—considering altitude, temperature, humidity, and annual temperature range—and women’s menopausal experiences. This study aims to interpret how these environmental factors influence the age of onset, severity of symptoms such as hot flushes and night sweats, and other long-term effects of menopause. Understanding these relationships addresses a significant gap in current knowledge and could guide future public health strategies. Methods: Through a comprehensive analysis of three cross-continental studies involving 1500 postmenopausal women from Spain, South American countries (Ecuador, Panama, Chile), various climates in Türkiye (Black Sea, Mediterranean, Continental), and the United Arab Emirates (UAE), this review evaluates diverse environmental impacts. Studies were selected based on their methodological rigor, geographical diversity, and focus on the unique and personal experiences of menopause. Data was collected via questionnaires and routine medical checkups, analyzing demographic, lifestyle, mood, symptom severity, and onset age variables. Results: Preliminary analysis indicates that 52.5% of participants from Spanish-speaking countries and the UAE reported vasomotor symptoms, with those in higher temperatures and lower altitudes experiencing exacerbated symptoms. Notably, Mediterranean climates were associated with an earlier menopause onset. Seasonal changes had minimal impact across all regions, suggesting lifestyle and other environmental factors play a more significant role. Conclusions: The findings highlight a clear link between climate-related geographical factors and the menopausal experience. Women in warmer, lower-altitude regions suffer more severe symptoms, while those in Mediterranean climates face earlier onset. The absence of significant seasonal variations across the studies underscores the predominance of lifestyle and environmental factors over purely climatic conditions. These insights pave the way for targeted interventions and support the need for further public health research into the complex interactions between climate change and menopause.

文摘Based on the account of the vital role which the national finance played in supporting agriculture,the thesis presents the current situation of financial support for agriculture in China,in terms of the limited scale and irrational structure of financial support expenditure in agriculture.On the basis of the brief introduction of the current level of Chinese farmers' income,the thesis discusses the effects of scale and irrational structure of financial support expenditure in agriculture on the farmers' income,according to the related data of financial support expenditure in agriculture and rural per capita net income.The results indicate that the calculating regression equation has a remarkable explanation power,reflecting the positive role of financial support expenditure in agriculture played by national finance in increasing the farmers' income.As regards the structure of financial support expenditure in agriculture at present,according to the proportion from high to low,the expenditure primarily consists of three parts from high to low in sequence as follows:productive expenditure and funds for public undertakings,capital construction expenditure,and rural relief expenditure plus science and technology funds.Such sequence deviates from the marginal production effects of financial support expenditure in agriculture and the correlation of farmers' income,which demonstrates the severe irrationality of the structure of financial support expenditure in agriculture.Corresponding countermeasures are put forward as follows:on one hand,we should continue intensifying the efforts to support agriculture financially in order to form a regular increase mechanism;on the other hand,we should adjust and optimize the structure of financial support expenditure in agriculture,and further crystallize the investment flows.

文摘Background:The relationship between diet and intestinal microbiota and mucin composition appears to be fundamental for poultry gut health.The effects of insect meal(whose role as alternative feed ingredient is now well recognized)on gut microbiota and mucin composition have recently been reported in Tenebrio molitor-fed free-range and broiler chickens,but no data are currently available for Hermetia illucens(HI)-fed broilers.The present study evaluated the effects of dietary HI meal inclusion on cecal microbiota and intestinal mucin composition of broiler chickens.Results:A total of 256 male broiler chickens were allotted to 4 dietary treatments(control diet[C]and 5%,10%and 15%HI meal inclusion,with 8 replicate pens/treatment and 8 birds/pen)and slaughtered at 35 d of age(2 animals/pen,16 birds/diet).The cecal microbiota assessment by 16S rRNA amplicon based sequencing showed lower alpha diversity in HI15 chickens(Shannon,P<0.05)and higher beta diversity(Adonis and ANOSIM,P<0.001)in birds fed HI diets than C.Furthermore,HI15 birds displayed significant increase of the relative abundance of Proteobacteria phylum(False Discovery Rate[FDR]<0.05)when compared to HI10.L-Ruminococcus(Ruminococcus from Lachnospiraceae family),Faecalibacterium,Blautia and Clostridium genera were found to be characteristic of HI5 cecal microbiota(FDR<0.05),while broiler chickens fed HI10 and HI15 diets were characterized(FDR<0.05)by Lactobacillus and Ruminococcus(HI10)and Bacteroides,Roseburia and Helicobacter genera(HI15).Periodic-acid Schiff,Alcian Blue pH 2.5 and high iron diamine staining on small and large intestine also demonstrated lower mucin staining intensity in the intestinal villi of HI10 and HI15 birds than C(P<0.05).Conclusions:Dietary HI meal utilization at low inclusion levels(i.e.,5%)positively influenced either the cecal microbiota or the gut mucin dynamics in terms of selection of potentially beneficial bacteria and increase in villi mucins.However,high inclusion levels(in particular the 15%)may have a negative influence in terms of partial reduction of microbial complexity,reduction of potentially beneficial bacteria,selection of bacteria with mucolytic activity and decrease in villi mucins.
文摘We aim to review the literature and provide guidance on preventive health measures in inflammatory bowel disease(IBD). Structured searches were performed in Pub Med,MEDLINE,EMBASE,Web of Science and Cochrane Library from January 1976 to June 2016 using the following keywords:(inflammatory bowel disease OR Crohn's disease OR ulcerative colitis) AND(health maintenance OR preventive health OR health promotion). Abstracts of the articles selected from each of these multiple searches were reviewed,and those meeting the inclusion criteria(that is,providing data regarding preventive health or health maintenance in IBD patients) were recorded. Reference lists from the selected articles were manually reviewed to identify further relevant studies. Patients with IBD are at increased risk of developing adverse events related to the disease course,therapeutic interventions,or non-adherence to medication. Recent studies have suggested that IBD patients do not receive preventive services with the same thoroughness as patients with other chronic diseases. Preventive health measures can avert morbidity and improve the quality of life of patients with IBD. Gastroenterologists and primary care physicians(PCPs) should have an up to date working knowledge of preventive health measures for IBD patients. A holistic approach and better communication between gastroenterologists and PCPs with explicit clarification of roles will prevent duplication of services and streamline care.
文摘Background: The Women’s Health Initiative (WHI) published findings in 2002 that changed the perception of the use of hormone replacement therapy (HRT) for the reduction of cardiovascular risks. Menopausal women using HRT for the relief of vasomotor symptoms were advised to use the lowest possible dose of HRT over the shortest possible duration. Objective: This study sought to examine patterns of HRT use for the treatment of menopausal symptoms before and after the WHI among women at least 40 years of age. Methods: A retrospective analysis was performed on a total of 1367 women in the pre-WHI group and 6467 women in the post-WHI group using the U.S. General Electric (GE) Centricity electronic medical record database. Menopause diagnosis was assessed using ICD-9 codes. Clinical characteristics and medication use were assessed for women with at least 3 years of enrollment (1 year baseline, 2 years follow-up). Results: The proportion of women in the post-WHI group that initiated HRT was significantly less than that of women in the pre-WHI group (31.3% vs. 56.9%, respectively;p < 0.001). Combination HRT use declined significantly (21.9% pre-WHI cohort vs. 7.2% post- WHI cohort, p < 0.001) among increases in non-HRT use, namely SSRIs (15.2% pre-WHI cohort v. 22.3% post-WHI cohort, p < 0.001) and tranquilizers (9.5% pre-WHI cohort v. 15.8% post-WHI cohort, p < 0.001). Conclusion: The results of the WHI 2002 publication made an impression on the perception of HRT’s role in the relief of menopausal symptoms. Decision-making on the part of women seeking treatment for vasomotor symptoms and women’s health professionals demonstrates that despite HRT precautions, women continue to exhibit a need for HRT use. This study’s findings suggest that women seeking treatment for menopausal symptom relief and women’s health professionals continue to work together to find the appropriate balance between therapy use and adherence to therapy use guidelines.
