Contamination and human health risk assessment of heavy metal(loid)s in topsoil and groundwater around mining and dressing factories in Chifeng,North China

Chifeng is a concentrated mining area for non-ferrous metal minerals,as well as a key prevention and control area for heavyduty enterprises.This situation necessitates an efective ecological and human health risk assessment of heavy metal(loid)s driven by the wide distribution of metal ore processing,mining,and smelting factories in Hexigten Banner and Bairin Left Banner.We conducted surveys to assess the levels of heavy metal(loid)s(Cr,As,Pb,Cd,and Hg)in the topsoil and groundwater of the areas.The results indicated that the concentrations of As,Cd,and Pb in partial soil samples exceeded the environmental quality standards of Grade II.Based on contamination assessments,such as geoaccumulation indices and pollution indices,we inferred that Cd,Pb,and As were primary pollutants in topsoil.Potential ecological risks when considered as part of the average risk indices(RI)are up to 1626.40 and 2818.76,respectively,in the two areas.Comparative analysis revealed that Cd posed a very high potential ecological risk,followed by As.Moreover,the evaluation showed that the three exposure pathways of carcinogenic and non-carcinogenic risk followed a descending order:inhalation>ingestion>dermal contact,except for Pb.Arsenic in topsoil posed a potential non-carcinogenic risk to human health,while there were no adverse efects of As in groundwater.In addition,the average total carcinogenic risk for As in the two areas,as well as the risk of Pb in the topsoil of Bairin Left Banner and all the fve heavy metal(loid)s in groundwater,exceeded human tolerance.Pb–Zn mines caused higher human health risks.In addition,the tandem contamination of heavy metal(loid)s in soil and groundwater was not obvious.This research study provides a basis for pollution remediation to control heavy industry-induced ecological and health risks of heavy metal(loid)s.

Path Breakthrough of Medical Humanities Education From the Perspective of“All-Staff,Whole-Process,and All-Round Education”

Medical education is an important cornerstone for the development of healthcare,and medical humanities education,as an integral part of medical education,plays an irreplaceable role in cultivating people’s health guardians with high medical ethics.We adopted the method of stratified random sampling to select 309 students and 107 faculty members from three independent medical colleges in Sichuan province as the research subjects and distributed questionnaire surveys investigating in three dimensions:overall cognition of medical humanities,evaluation of medical humanistic qualities,and the current situation of medical humanities education,supplemented by an in-depth literature review and interviews with subject matter experts.We found that“tech-centrism”still has a great influence,the self-evaluation of medical students’humanistic quality is generally not high,the educational concept of“emphasizing professional skills over morality”of faculty and staff is still quite prevalent,and there is still the“last mile”phenomenon in medical humanities education.In order to promote the integrated development of“new medicine”and“new liberal arts”and break the barriers of“tech-centrism”and“instrumental rationality,”it is necessary to change the educational concept and strengthen the education of all employees,break through the bottleneck of internships and strengthen the whole process of education,integrate educational resources and strengthen all-round education,improve the incentive mechanisms,strengthen the assessment methods,and provide Chinese wisdom and Chinese solutions for the development of medical humanities education.

The two-way feedback and passing-way of human body

Two-way feedback of human body was published in 1992. The sensation of two-way feedback of body is a special system of human reaction, which maintains and regulates symmetry and balance of human body. The human two-way feedback reacts to human health. For human overall health and delay decrepitude, it is necessary to pay attention to the stimulations (passive acceptance and initiative interventions) and relevant influences in human body and the stimulative effect. In this paper, the experimental research of stimulation and an example of two-way feedback in human body are given. And lay a foundation of prevention, medical treatment and hygiene of human overall health.

For People's Right to Safety Of Lives and Health——On development of health-related human rights in China

Medical and health work constitutes the prerequisite to protection of the people's right to safety of lives and health. Over the past decades, the Chinese Government has spared no effort in this regard and, as a result, the Chinese people's health has significantly improved. In the nationwide fight against the SARS (severe acute respiratory syndrome) epidemic in the first half of 2003, the Government placed the health of the Chinese people and the safety of their lives above everything else. With a huge input of human, financial and material resources, the country won a decisive victory over the epidemic. Following is the full text of an interview by Human Rights with Gao Qiang, executive vice-minister of the Ministry of Health, on China's medical and health work and how it is related to protection of human rights.

Communicating Different and Higher across the Praxis of Bloom’s Taxonomy While Shifting toward Health at Every Size (HAES)

The majority of recent studies on prevention and control of childhood obesity focus on methods for achieving weight loss. In contrast, the Health at Every Size (HAES) paradigm fosters improved health behaviors for people of all sizes by emphasizing natural diversity of body type and attention to social, emotional, and spiritual factors in addition to physical ones. This study examined introduction of the HAES paradigm to student teachers using different communication models while moving across the learning domains of Bloom’s Taxonomy. The qualitative research tested a face-to-face verbal communication model and a Computer-Mediated Communication (CMC) module and its blog. It was also based upon reflection diaries recorded by participants using both models. Participants included Druze, Jewish, and Bedouin students at a teacher training program in northern Israel. The student teachers succeeded in developing the HAES concepts further while demonstrating the higher domain levels across Bloom’s Taxonomy. These higher levels emerged when engaging with theoretical concepts and practical dilemmas relating to the HAES concepts of health promotion, body image, well-being, and self-worth. Challenging the appreciation of HAES using different communication models can be translated into diverse contexts of Health Education Practices.

The Way Food, Diet, and Exercise Are Communicated in Women’s Health Magazine: From a Critical Perspective

Women’s Health Magazine creates a fantasy world for many women,in which they can attach themselves to the ideal beauty standards,and work towards reaching those ideals by engaging in diet and exercise.The advertisements in this magazine mostly give value to the Western ideal of white beauty,which is about the slenderness of the feminine physical body.However,the white beauty ideal makes women in different cultures such as the Turkish and Latin women to resemble this ideal by changing their darker hair colors to blonde,changing their darker eye colors to blue,and changing their curvy body types to slim;even though,their curviness represents sexual desire in their specific culture,and thus it leads these women to lose their cultural characteristics that make them more feminine(Mendible,2007,pp.3-8).In other words,the white ideal beauty causes many women in other cultures to have some kind of cultural assimilation in terms of their own beauty standards,and instead cause them to embrace an international standard of beauty that is Western,and many women such as the Turkish and Hispanic,as well as,the Korean,Chinese,and Japanese,undergo some kind of a process of cultural assimilation related to their cultural body characteristics,as a result(Yan&Bissell,2014,p.197).In other words,these women lose their indigenous body characteristics and they instead try to resemble the slender ideal body of the West with the spread of globalization,which has a major influence on that(Hoskins,2014,p.110).The aim of this paper is to show how the Women’s Health Magazine,a popular contemporary magazine,crates a discourse on food,diet,and exercise,which have a major influence in shaping and assimilating the body type of Turkish women from a critical perspective.

Transition to adulthood: A critical role for exercise in building overall well-being

A growing number of multidisciplinary studies have reported the beneficial effects of physical activities towards the development of overall well-being and the reduction of chronic illnesses. Physical inactivity is a serious worldwide problem and is considered the key lifestyle factor that negatively influences health and function of individuals. Here we propose that growth kinetics of body and mind and associated disproportionate physical activity may have considerable effects on the increased physical and mental illnesses and premature death rates currently observed in mid to late adulthood people. Children and young adults, being in exponential growth phase and self-motivated to engage in physical activity, possess more cognition, resilience, and mind-body-emotion-spirit integration. In contrast, as our body transitions into adulthood, there is a decline in the growth of body and mind. Furthermore, in this period, adults experience the increased stressors of career and financial demands, time pressure, and family responsibilities. The decline in growth combined with prolonged stress appears to result in reduced cognition, resilience, and mind-body-emotion-spirit integration, leading to sedentary and other faulty lifestyles, which could further lead to a predisposition to maladaptive behaviours and various chronic diseases at a later stage. In agreement with this, currently more than two thirds of the adult population across the world are physically inactive and are failing to perform the daily recommended guidelines of moderate to vigorous exercise. As negative changes and faulty lifestyles begin to occur during and after adulthood transition, creating awareness in people between 29 to 35 years of age about mindful exercise should be considered a national priority. This would allow adults to achieve overall well-being, and increased productivity and life expectancy, reducing health care-associated economic burden placed on the nation.

Female genital schistosomiasis,human papilloma virus infection,and cervical cancer in rural Madagascar:a cross sectional study

Background Women’s health in resource-limited settings can benefit from the integrated management of high-burden diseases,such as female genital schistosomiasis(FGS)and human papilloma virus(HPV)-related cervical cancer.In schistosomiasis-endemic countries such as Madagascar,data on FGS and HPV prevalence are lacking as well as preventive measures for both conditions.This study aims to estimate the prevalence of FGS and HPV in rural Madagascar,and to examine associated risk factors to identify opportunities for improving women’s health.Methods After initial community outreach activities,interested women aged 18-49 years were recruited consecutively in 2021 at three primary health care centers in the district of Marovoay.FGS was detected by colposcopy.Colposcopy images were double-blind reviewed by two independent specialists.A Luminex bead-based assay was performed on cervical vaginal lavage specimens for HPV typing.Crude(CPR)and adjusted prevalence ratios(APR)of associations between selected factors and FGS and HPV positivity were estimated using univariable and multivariable binary Poisson regression with 95%confidence intervals(CIs).Results Among 500 women enrolled,302 had complete information on FGS and HPV diagnosis,and were thus eligible for analysis.Within the sample,189(62.6%,95%CI:56.9-68.1)cases of FGS were detected.A total of 129 women(42.7%,95%CI:37.1-48.5)tested positive for HPV.In total,80 women(26.5%,95%CI:21.6-31.8)tested positive for both conditions.No association was observed between FGS and HPV positivity,while previous pregnancy(APR=0.65,95%CI:0.43-0.78)and older age(APR=0.59,95%CI:0.42-0.81)are showing a negative association with HPV infection compared to no previous pregnancy and younger age groups.Conclusions The results of the study show that FGS and HPV are highly prevalent in rural Madagascar.The concurrent prevalence of these two conditions requires urgent adaptations of public health strategies to improve women’s health,such as integrated services at primary level of care.
