The use of solid fuel for cooking and heating is the main source of IAP in developing countries, accounting for an estimated 3.5 million deaths and 4.5% of Disability-Adjusted Life Years in 2010. Other sources of IAP include indoor smoking, infiltration of pollutants from outdoor sources and substances emitted from an array of human utilities and biological materials. Children are among the most vulnerable groups for adverse effects of IAP. The respiratory system is a primary target of air pollutants resulting in a wide range of acute and chronic effects. The spectrum of respiratory adverse effects ranges from mild subclinical changes and mild symptoms to life threatening conditions and even death. However, IAP is a modifiable risk factor having potential mitigating interventions. Possible interventions range from simple be-havior change to structural changes and from shifting of unclean cooking fuel to clean cooking fuel. Shifting from use of solid fuel to clean fuel invariably reduces the household air pollution in developing countries, but such a change is challenging. This review aims to summarize the available information on IAP exposure during childhood and its effects on respiratory health in developing countries. It specifically discusses the common sources of IAP, susceptibility of children to air pollution, mechanisms of action, common respiratory conditions, preventive and mitigating strategies.展开更多

Materials and Methods: The study is cross-sectional and descriptive in a quantitative research design. The “Attitude Scale for Physicians toward Occupational Health and Occupational Diseases” developed by Kolcu et al. was used in the study (Cronbach’s α 0.94). Our study aimed to sample the entire country using the stratified sample selection based on geographical region. 349 family physicians were included in the study according to sample size (n: 349). Results: The mean age of the participants in the study was 37.77 ± 8.96 (min: 27, max: 65 years). Of the participants, 65.2% were male. Of the physicians, 33.8% were family medicine specialists, and 38.8% had occupational physician certificates. It was determined that the level of attitude of family physicians toward occupational diseases was insufficient. It was also found that awareness increased as age increased, and awareness and attitude levels did not change according to gender. No significant difference was found in the scale total scores and subdimensions of family physicians’ occupational health and occupational disease attitudes according to the regions they worked in Türkiye. Conclusion: It has been concluded that there is no difference in awareness among family physicians in regions where it is much more important to diagnose an occupational disease, especially in industrial regions. The number of family physicians with occupational physician certificates was very insufficient, and a significant number of those who had occupational physician certificates did not practice occupational medicine.展开更多

Methods: One hundred and two rural elderly hypertensive patients aged 65-80 years were selected and randomly divided into an experimental and control group of 51 each. The control group implemented conventional health education, and the experimental group implemented FCEM health education through WeChat platform for 4 consecutive weeks. The Therapeutic Adherence Scale for Hypertensive Patients (TASHP) scores and blood pressure measurements were compared between and within the two groups. Results: After the intervention, there were significant differences in medication compliance and blood pressure between the two groups (P < 0.001). In the control group, before and after the intervention, there was a significant difference in medication compliance (P < 0.001), but no significant difference in blood pressure (P > 0.05). In the experimental group, there were significant differences in medication compliance and blood pressure before and after the intervention (P < 0.001). Conclusion: The FCEM health education through an online social platform significantly improved medication compliance and led to effective blood pressure control in rural elderly hypertensive patients. Therefore, as an effective, safe, and economical model, it is also necessary to explore its effectiveness in improving health problems in other chronic diseases and other age groups.展开更多

文摘OBJECTIVE:To elucidate the anti-inflammatory mechanisms of modified Shoutai pills(改良寿胎丸,MSTP)in miscarriages,we performed transcriptome sequencing on the decidua and placental tissues of pregnancy mice.METHODS:The therapeutic effects and antiinflammatory mechanisms of MSTP were studied in mice with lipopolysaccharide(LPS)-induced miscarriage.First,the effects of MSTP on pregnancy outcomes and the maternal-fetal interface,in LPS-induced miscarriage mice were examined.RNA sequencing was used to further investigate gene expression changes in LPS-induced miscarriage mice and to assess the effects of MSTP intervention.Finally,the expression levels of inflammation-related genes in the decidua and placental tissues were determined using quantitative real-time polymerase chain reaction(q RT-PCR).RESULTS:A high dose of MSTP significantly decreased the resorption rate(P<0.05)and reduced apoptosis of the decidua and placental tissues in mice.Gene ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses showed that inflammatory and immune-related signals were enriched.q RT-PCR results confirmed that in decidual and placental tissues,MSTP reduced the gene expression levels of toll-like receptor 4(TLR4),nuclear factor kappa-B(NF-κB),c-Jun N-terminal kinase 1,p38,and tumor necrosis factor-α.CONCLUSIONS:In this study,we demonstrated that MSTP effectively prevented embryo loss with an antiinflammatory mechanism through downregulation of the TLR4-NF-κB/MAPK signaling pathway,in LPS-induced miscarriage mice model.To our knowledge,this is the first study to reveal the therapeutic mechanism of MSTP in LPS-induced miscarriage in mice.

文摘Scientific integrity is a learned skill.When researchers and students learn integrity in laboratories or in the classroom,they are empowered to use similar principles in other aspects of their lives.This commentary reviews the concepts related to scientific integrity at a time when science faces important challenges related to the increase number of articles produced regarding research on coronavirus disease 2019(COVID-19).Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has ignited another parallel viral pandemic,with science ranging from robust studies to dishonest studies being conducted,posted,and shared at an unprecedented rate.A balance is needed between the benefits of the rapid access to new scientific data and the threat of causing panic or erroneous clinical decisions based on mistakes or misconduct.The truth is that the“scientific research has changed the world”but now,and more than ever,“it needs to change itself”.A pandemic with a“paperdemic”will be even more complicated to manage if it progresses in an uncontrolled manner and is not properly scrutinized.
文摘Implementing national to community-based 'One Health' strategy for human,animal and environmental challenges and migrating-led consequences offer great opportunities,and its value of sustained development and wellbeing is an imperative.'One Health' strategy in policy commitment,partnership and financial investment are much needed in advocacy,contextual health human-animal and environmental development.Therefore,appropriate and evidence-based handling and management strategies in moving forward universal health coverage and sustainable development goals (SDGs) are essential components to the China-Africa health development initiatives.It is necessary to understand how to strengthen robust and sustainable 'One Health' approach implementation in national and regional public health and disaster risk reduction programs.Understanding the foundation of'One Health' strategy in China-Africa public health cooperation is crucial in fostering health systems preparedness and smart response against emerging and re-emerging threats and epidemics.Building the value of China-Africa 'One Health' strategy partnerships,frameworks and capacity development and implementation through leveraging on current and innovative China-Africa health initiatives,but also,mobilizing efforts on climatic changes and disasters mitigation and lifestyle adaptations strategies against emerging and current infectious diseases threats are essential to establish epidemic surveillance-response system under the concept of global collaborative coordination and lasting financing mechanisms.Further strengthen local infrastructure and workforce capacity,participatory accountability and transparency on 'One Health' approach will benefit to set up infectious diseases of poverty projects,and effective monitoring and evaluation systems in achieving African Union 2063 Agenda and SDGs targets both in Africa and China.
文摘Indoor air pollution(IAP) is a key contributor to the global burden of disease mainly in developing countries. The use of solid fuel for cooking and heating is the main source of IAP in developing countries, accounting for an estimated 3.5 million deaths and 4.5% of Disability-Adjusted Life Years in 2010. Other sources of IAP include indoor smoking, infiltration of pollutants from outdoor sources and substances emitted from an array of human utilities and biological materials. Children are among the most vulnerable groups for adverse effects of IAP. The respiratory system is a primary target of air pollutants resulting in a wide range of acute and chronic effects. The spectrum of respiratory adverse effects ranges from mild subclinical changes and mild symptoms to life threatening conditions and even death. However, IAP is a modifiable risk factor having potential mitigating interventions. Possible interventions range from simple be-havior change to structural changes and from shifting of unclean cooking fuel to clean cooking fuel. Shifting from use of solid fuel to clean fuel invariably reduces the household air pollution in developing countries, but such a change is challenging. This review aims to summarize the available information on IAP exposure during childhood and its effects on respiratory health in developing countries. It specifically discusses the common sources of IAP, susceptibility of children to air pollution, mechanisms of action, common respiratory conditions, preventive and mitigating strategies.
文摘Objective To evaluate the association between serum uric acid(SUA)and kidney function decline.Methods Data was obtained from the China Health and Retirement Longitudinal Study on the Chinese middle-aged and older population for analysis.The kidney function decline was defined as an annual estimated glomerular filtration rate(e GFR)decrease by>3 mL/min per 1.73 m^(2).Multivariable logistic regression was applied to determine the association between SUA and kidney function decline.The shape of the association was investigated by restricted cubic splines.Results A total of 7,346 participants were included,of which 1,004 individuals(13.67%)developed kidney function decline during the follow-up of 4 years.A significant dose-response relation was recorded between SUA and the kidney function decline(OR 1.14,95%CI 1.03-1.27),as the risk of kidney function decline increased by 14%per 1 mg/d L increase in SUA.In the subgroup analyses,such a relation was only recorded among women(OR 1.22,95%CI 1.03-1.45),those aged<60 years(OR 1.22,95%CI 1.05-1.42),and those without hypertension and without diabetes(OR 1.22,95%CI 1.06-1.41).Although the dose-response relation was not observed in men,the high level of SUA was related to kidney function decline(OR 1.83,95%CI 1.05-3.17).The restricted cubic spline analysis indicated that SUA>5 mg/dL was associated with a significantly higher risk of kidney function decline.Conclusion The SUA level was associated with kidney function decline.An elevation of SUA should therefore be addressed to prevent possible kidney impairment and dysfunction.
文摘An increasing variety of research practices are converging into information science mainstream—potentially.They are accompanied by astounding new uses of knowledge and even more astounding social transformations that revolve around information technologies.Whether a robust information science will finally emerge may not only-depend on successful discussions about the philosophy of information and the social impact of the new technologies.The most important adjustment to make is about framing a"new way of thinking"within information science itself:an inner philosophy interconnecting research practices in fundamental areas of the new science.Like in the historical birth of other major sciences,the empirical,comparative understanding of informational phenomena and informational entities should take place first.In the end,crafting a great scientific domain around information science should be a common ambition for all the scholars and researchers involved in these new studies.
文摘Chemical hazards have been an object of public concern all over the world. The greatest problems are classified into two categories. One is environmental pollution. During the rapid industrialization of Japan, environmental pollution from industrial wastes produced many victims. Reflecting on past conduct, most problems are now being solved by setting strict standards for emission. However, there have been some cases that health hazards are revealed with the aging of the exposed people.
文摘Background/Aim: This study evaluated family physicians’ attitudes toward occupational health and disease in Türkiye. Materials and Methods: The study is cross-sectional and descriptive in a quantitative research design. The “Attitude Scale for Physicians toward Occupational Health and Occupational Diseases” developed by Kolcu et al. was used in the study (Cronbach’s α 0.94). Our study aimed to sample the entire country using the stratified sample selection based on geographical region. 349 family physicians were included in the study according to sample size (n: 349). Results: The mean age of the participants in the study was 37.77 ± 8.96 (min: 27, max: 65 years). Of the participants, 65.2% were male. Of the physicians, 33.8% were family medicine specialists, and 38.8% had occupational physician certificates. It was determined that the level of attitude of family physicians toward occupational diseases was insufficient. It was also found that awareness increased as age increased, and awareness and attitude levels did not change according to gender. No significant difference was found in the scale total scores and subdimensions of family physicians’ occupational health and occupational disease attitudes according to the regions they worked in Türkiye. Conclusion: It has been concluded that there is no difference in awareness among family physicians in regions where it is much more important to diagnose an occupational disease, especially in industrial regions. The number of family physicians with occupational physician certificates was very insufficient, and a significant number of those who had occupational physician certificates did not practice occupational medicine.
文摘Appropriate oral hygiene significantly reduces the possibility of oral infections.However,dental caries and periodontal diseases are major oral health issues causing chronic diseases due to poor oral health.Recently,herbal compounds have gained interest in maintaining oral health.Extracts of burdock root(Arctium),noni fruit(Morinda citrifolia),and neem leaf(Azadirachta indica)are now used as intracanal medicaments in endodontics and periodontics.Plectranthus amboinicus species and other plants produces essential oil likeβ-caryophyllene,p-cymene,andγ-terpinene can exhibit antibacterial activity;highlighting phytoconstituents plays a vital role in oral health.The COVID-19 pandemic highlighted the importance of hygiene and sanitization,to curb SARS-CoV-2.Oral cavity is among the gateways for virus entry into saliva.Saliva is a potential reservoir of SARS-CoV-2,and there is an increased risk of infection if there is any fissure in the mouth.This enables entry of virus into the vascular system through gingival or periodontal pocket,possibly reaching lung periphery then to lung vessels by interacting with endothelial surface receptors triggering pulmonary vasoconstriction and lung damage due to endothelial dysfunction.This review aims to draw attention to the possible route of SARS-CoV-2 infection via the oral cavity and the importance of oral hygiene against COVID-19.

文摘Anterior cruciate ligament(ACL)injuries are frequently caused by sports injuries and trauma.In cases involving complete tears,ACL reconstruction(ACLR)surgery is the only way to restore the ligament’s integrity.When selecting a graft,both the potential complications and the mechanical properties and healing efficacies should be considered.Artificial ligaments have been widely applied in clinical ACLR,and most have exhibited satisfactory biocompatibility and short-term follow-up results.Compared with autografts and allografts,however,the lack of bioactivity of currently available artificial ligaments is a major disadvantage.In addition,some long-term follow-up results have revealed other drawbacks of artificial ligaments,such as graft failure and other complications.Here,we summarize attempts to enhance the bioactive performance of artificial ligaments,as such modifications may have good potential for clinical translation and could improve the long-term outcomes of existing products.
文摘Objective: To validate the effectiveness of a Family-Centered Empowerment Model (FCEM) health education through WeChat on medication compliance and blood pressure among elderly hypertensive patients in rural areas. Methods: One hundred and two rural elderly hypertensive patients aged 65-80 years were selected and randomly divided into an experimental and control group of 51 each. The control group implemented conventional health education, and the experimental group implemented FCEM health education through WeChat platform for 4 consecutive weeks. The Therapeutic Adherence Scale for Hypertensive Patients (TASHP) scores and blood pressure measurements were compared between and within the two groups. Results: After the intervention, there were significant differences in medication compliance and blood pressure between the two groups (P < 0.001). In the control group, before and after the intervention, there was a significant difference in medication compliance (P < 0.001), but no significant difference in blood pressure (P > 0.05). In the experimental group, there were significant differences in medication compliance and blood pressure before and after the intervention (P < 0.001). Conclusion: The FCEM health education through an online social platform significantly improved medication compliance and led to effective blood pressure control in rural elderly hypertensive patients. Therefore, as an effective, safe, and economical model, it is also necessary to explore its effectiveness in improving health problems in other chronic diseases and other age groups.

文摘Background:Immune checkpoint inhibitors(ICIs)are effective in a subset of patients with metastatic solid tumors.However,the patients who would benefit most from ICIs in biliary tract cancer(BTC)are still controversial.Materials and methods:We molecularly characterized tissues and blood from 32 patients with metastatic BTC treated with the ICI pembrolizumab as second-line therapy.Results:All patients had microsatellite stable(MSS)type tumors.Three of the 32 patients achieved partial response(PR),with an objective response rate(ORR)of 9.4%(95%confidence interval[CI],2.0–25.2)and nine showed stable disease(SD),exhibiting a disease control rate(DCR)of 37.5%(95%CI,21.1–56.3).For the 31 patients who had access to PD-1 ligand 1(PD-L1)combined positive score(CPS)testing(cut-off value≥1%),the ORR was not different between those who had PD-L1-positive(PD-L1+;1/11,9.1%)and PDL1-(2/20,10.0%)tumors(p=1.000).The tumor mutational burden(TMB)of PD-L1+BTC was comparable to that of PD-L1-BTC(p=0.630).TMB and any exonic somatic mutations were also not predictive of pembrolizumab response.Molecular analysis of blood and tumor samples demonstrated a relatively high natural killer(NK)cell proportion in the peripheral blood before pembrolizumab treatment in patients who achieved tumor response.Moreover,the tumors of these patients presented high enrichment scores for NK cells,antitumor cytokines,and Th1 signatures,and a low enrichment score for cancer-associated fibroblasts.Conclusions:This study shows the molecular characteristics associated with the efficacy of pembrolizumab in BTC of the MSS type.
