The World Health Organization ...Introduction: Refractive error is recognized as one of the most important causes of correctable visual impairment and affects people of all ages, socioeconomic levels, and ethnic groups. The World Health Organization (WHO) estimated 285 million people globally were visually impaired, with 39 million blinds. The aim of this study is to access the knowledge, attitudes, and practices of health sciences students about the refractive error in Nampula, Mozambique. Material and Methods: Descriptive cross-sectional study including health sciences students of Lúrio University in Nampula, applying a questionnaire to access their knowledge, attitudes, and practices concerning the refractive error. The collected data were entered into SPSS version 22.0 for analysis. Frequency distribution and central tendency measures (mean, median) were used to summarize the descriptive part of the study. Results were described using tables and running text. Sample students were included after obtaining informed consent. Results: A total of 298 students participated in the study, 50.3% female, with average age of 24 ± 5.4 years. 69.8% had an eye exam and 54.7% believe they have good vision, 58.1% say that wearing glasses is the main method of correcting refractive errors. 92.3% refer to the Central Hospital as the best place to provide eye health services. The main reason for not purchasing the glasses was their cost (47.3%) and the alternative method for spectacle users was contact lenses (81.0%). The students’ attitudes were positive towards the use of glasses. Conclusion: Visual health education about the knowledge, attitudes and practices regarding refractive errors among students must be intensified to ensure good dissemination of information in the surrounding communities enrolled in the health promotion program “One Student, One Family” implemented by Lúrio University in Nampula.展开更多

In contrast, serum creatine levels were unaffected by exercise(p = 0.80), while creatinine levels exhibited a strong tendency to decrease post-exercise(from [81.8 ±17.5] μmol·L^(-1) to [73.1 ± 11.6] μmol·L^(-1);p = 0.06). A comparison of the slopes of the two regression lines(saliva vs. serum) revealed significant differences for both creatine(p = 0.01) and creatinine(p = 0.03).Conclusions: The above findings suggest a potential difference in the dynamics of creatine metabolites in these two bodily fluids, both pre and post-exercise.展开更多

The objective of this work is to contribute to the management of OF cases in CAR. Patients and Methods: This was a retrospective, descriptive and analytical study, including data from several OF care services. The study included 245 cases of OF, operated on from 2009 to 2018. The parameters studied were maternal and obstetrical data, sociodemographic data, the specific characteristics of the fistulas as well as the modalities and outcome of surgical treatment. The data collected came from six (6) OF surgical repair campaigns organized by the Ministry of Health and Population with the support of UNFPA. Results: We recorded 245 patients, representing a prevalence of 0.77% of OF per year. Among these patients, almost half (45.3%) were treated at the Sino-Central African Friendship University Hospital Center (CHUASC). The average age of the patients was 30 years (range 14 to 78 years). They were unschooled (53.9%) and primigravidas (35%). The fistulas had an average duration of evolution of 7.58 years. They were vesicovaginal in 25.3%. Types V and I dominated in 17.4% and 9.2%, respectively. In 85.9% of cases, fistulorrhaphy was performed, half of which (50.2%) via the upper route. The cure rate was 83.3%. Note that our study reveals statistically significant links between the evolution after surgery with age (p = 0.04 Conclusion: OF mainly affected women of childbearing age, uneducated, primiparous. Vesicovaginal fistula was the frequently encountered type and was manifested by urine loss clinically with a positive methylene blue test.展开更多

At this age, the diagnosis of rheumatic flare-ups can be difficult due to the frequency of other types of joint diseases and the existence of degenerative and dystrophic valve disease. In adults, the initial rheumatic attack is marked by the predominance of joint damage over cardiac damage. However, it is often at this age that rheumatic valve disease is discovered. The revised Jones criteria also find their place in the diagnosis of AAR in adults. Objective: To study the demographic, clinical, and biological characteristics of acute rheumatic fever (ARF) in the General Medicine Department of the Siguiri Prefectural Hospital. Materials and Methods: This descriptive observational study examined the demographic, clinical and biological characteristics of acute rheumatic fever (ARF) at the Siguiri Prefectural Hospital, Guinea, between April 1 and September 31, 2021 according to Jones criteria. The data were collected on a form containing sociodemographic variables (age, sex, profession), rheumatological, cardiac, pulmonary and neurological clinical signs, biological variables and treatment. Results: Figure 1 shows the flow of the hospital frequency of the RAA in the General Medicine Department of the Prefectural Hospital of Siguiri. During the study period, 420 patients were hospitalized, of whom 161 patients had AAR, a frequency of 38.33%. Table 1 shows the distribution of patients diagnosed with ARB, by sociodemographic characteristics. The average age was 44.7 ± 19.78 years and the extremes of 14 and 90 years, the female sex dominated with a ratio of 0.75. The informal sector was in the majority in 45.34% of cases and most were illiterate, i.e. 53.42%. In our study, the incidence was lower during the dry season than during the rainy season, a hot season with high rainfall and humidity, the rainy period was a provider with a peak in August and September. The lifestyle was characterized by overcrowding in 87.58% of patients. The main complaint was fever, i.e. 88.82%. Rheumatological manifestations such as arthritis were 98.14%, chest pain was 37.89% (61 cases). The diagnosis was confirmed by ASLO titration in 85.71% of patients and 98.55% (136 cases) had a titration greater than 400 U/ml. Conclusion: The results obtained from our study show a high prevalence of acute rheumatic fever, which makes it a worrying health problem in the Siguiri health district. Young female adult patients, married with an informal profession and not in school residing in Siguiri were the most encountered in our study. The main functional signs mentioned by the patients were fever, cough and abdominal pain;osteoarticular pain and chest pain dominated the clinical picture. Almost all of our patients had an ASLO titer greater than 400 U/ml and a positive C-reactive protein. Our results show a high risk of spread of acute rheumatic fever within the population of Siguiri. Due to the serious complications caused by acute rheumatic fever, particular attention must be paid to it by carrying out other, much larger studies in order to identify the problem of RAA.展开更多

The overuse of antibiotics is a key driver of antimicrobial resistance (AMR). This study surveyed antibiotic use and adherence to the World Health Organization (WHO) prescribing indicators at the Request Muntanga Hospital in the Kalomo District of Southern Province, Zambia. Materials and Methods: This cross-sectional study was conducted from July 2023 to September 2023 at Request Muntanga Hospital in Zambia and reviewed 600 medical record prescriptions which were issued from July 1, 2022 to June 30, 2023 using the WHO prescribing indicators. The collected data were analyzed using Statistical Package for Social Sciences version 23.0. Results: From the 600 prescriptions sampled, 1246 medicines were prescribed, with antibiotics making up 86.7% of the encounters. Additionally, the average number of drugs prescribed per encounter was 2.1 and the prevalence of polypharmacy was 61.3%. Further, 17.8% of medicines were prescribed as injectables. Furthermore, 76.7% of the drugs were prescribed from the Zambia Essential Medicines List and 38.9% by generic names. Conclusions: This study found a high use of antibiotics and deviations from the WHO/International Network of Rational Use of Drugs (INRUD) core prescribing indicators at the Request Muntanga Hospital indicating non-adherence to the prescribing indicators. There is a need to promote adherence to the WHO/INRUD core prescribing indicators to promote the rational use of antibiotics and prevent the emergence and spread of AMR.展开更多

The evolutionary aspects of the incidence of antibiotic resistance in Salmonella strains no longer seem to attract much interest in the Central African Republic (CAR), although salmonellosis remains a health problem requiring national and international surveillance. Methodology: The study conducted at the National Laboratory of Clinical Biology and Public Health, Bangui, Central African Republic (LNBCSP) was a retrospective descriptive study. The study duration was five years (January 2019 to December 2023). The study sample consisted of patients who underwent bacteriological testing of stool, blood and urine samples for Salmonella at the LNBCSP in Bangui during this period. Study variables were age, sex, year and bacteriological test results. Statistical tests were used to compare incidences. Relative risks (RR) were calculated to measure the degree of association. Results: From 2019 to 2023, we recorded 353 Salmonella strains, of which 5% were found in blood, 37% in urine and 58% in stool. Patient age ranged from 1 to 86 years, with a mean of 27 ± 22.05 years and a mode of 5 years. Children aged 0 to 14 years (34%) and females (55.81%) predominated. The highest rate of contamination by Salmonella strains was 1.69% in 2022. The overall incidence of salmonellosis was 6.72 in 2019, 7.05 in 2020, 6.91 in 2021, 16.9 in 2022 and 6.26 in 2023 per 1000 samples. Resistance was 30.47% to β_lactam antibiotics, 24.22% to fluroquinolones and 37.97% to Salmonella spp. For Salmonella arizonae strains, resistance was 20.25% to aminoglycosides, 43.67% to chloramphenicol and 7.59% to imipenem. Conclusion: Laboratory-based surveillance of antibiotic resistance in Salmonella strains is needed in both human and veterinary medicine. Another study based on molecular characterization will identify new antibiotic-resistant variants circulating in CAR.展开更多

Young athletes received either a 20 min TECAR(n = 24) or TENS(n = 26) session within 5 days following a hamstring injury, while the control(CON, n = 25)group was instructed to rest. Visual analogue scale(VAS), functional Assessment Scale for Acute Hamstring Injuries(FASH), straight leg raise test(SLR), and sit-and-reach scores(STR) were obtained prior to, immediately,24, and 48 h after therapy. Group differences were detected after therapy in VAS and FASH scores(p < 0.05).Compared to pre-therapy measurements, VAS scores showed a greater decrease in the TECAR group(-38.75% to-63.33%) than in the TENS group(-16.67% to-25.00%) and both were greater than in the CON group(-2.81%to-9.81%)(p < 0.05). The TECAR group improved FASH scores(28.57%–48.21%) more than the TENS group(15.89%–27.79%) and both groups more than the CON group(0%–8.33%)(p < 0.05). The increase in SLR and STR was greater in the TECAR group(6.26%–13.96%) than in the TENS(1.72%–9.53%) and CON groups(0%–3.03%). These results suggest that in the acute phase of hamstring injury, the use of TECAR and, to a lesser extent, TENS may relieve pain symptoms and bring some improvements in flexibility more than instructing patients to rest.展开更多

文摘Objective:The study aimed to determine the faculty of the health sciences students’knowledge and attitudes regarding the coronavirus disease 2019(COVID-19)pandemic.Materials and Methods:This cross-sectional survey was completed with 317 undergraduate students of one health sciences faculty in Turkey.The data were collected between March 1,2020,and March 15,2020,by face-to-face interviews using a questionnaire created by the researchers.Number,percentage,mean,standard deviation,and Pearson Chi-square test were used to evaluate the data.Results:In this study,a high proportion of students answered questions about COVID-19 correctly.About 55.8%of the students took partial precautions against COVID-19 to protect themselves against COVID-19 and“frequent washing of hands”was the most common precaution.We determined that the main reasons for not taking any precautions against COVID-19 were“low number of cases in Turkey”and“getting irritated by the mask.”About 98.4%of the participants were entirely/partially following the news on COVID-19,with social media being the most commonly used medium.Female students took more protective measures than male students.The 1st-year students had more positive thoughts about vaccination compared to those in the other classes.Conclusions:Although the knowledge of the students about COVID-19 was good in the first wave of the pandemic,more than half of the students stated that they partially complied with the protective measures.
文摘Introduction: Refractive error is recognized as one of the most important causes of correctable visual impairment and affects people of all ages, socioeconomic levels, and ethnic groups. The World Health Organization (WHO) estimated 285 million people globally were visually impaired, with 39 million blinds. The aim of this study is to access the knowledge, attitudes, and practices of health sciences students about the refractive error in Nampula, Mozambique. Material and Methods: Descriptive cross-sectional study including health sciences students of Lúrio University in Nampula, applying a questionnaire to access their knowledge, attitudes, and practices concerning the refractive error. The collected data were entered into SPSS version 22.0 for analysis. Frequency distribution and central tendency measures (mean, median) were used to summarize the descriptive part of the study. Results were described using tables and running text. Sample students were included after obtaining informed consent. Results: A total of 298 students participated in the study, 50.3% female, with average age of 24 ± 5.4 years. 69.8% had an eye exam and 54.7% believe they have good vision, 58.1% say that wearing glasses is the main method of correcting refractive errors. 92.3% refer to the Central Hospital as the best place to provide eye health services. The main reason for not purchasing the glasses was their cost (47.3%) and the alternative method for spectacle users was contact lenses (81.0%). The students’ attitudes were positive towards the use of glasses. Conclusion: Visual health education about the knowledge, attitudes and practices regarding refractive errors among students must be intensified to ensure good dissemination of information in the surrounding communities enrolled in the health promotion program “One Student, One Family” implemented by Lúrio University in Nampula.
文摘Background: We monitored changes in salivary creatine pre-and post-high-intensity exercise in young adults while also investigating the potential correlation between salivary and serum creatine levels.Method: Saliva and serum samples were collected before and immediately after an incremental running-toexhaustion treadmill test in fifteen young adults(mean age [23.9 ± 2.9] years, eight females), with samples analyzed for guanidinoacetic acid, creatine, and creatinine using a liquid chromatography–tandem mass spectrometry method.Results: Following exercise, there was a substantial elevation in salivary creatine levels from(17.5 ± 14.2)μmol·L^(-1) to(43.6 ± 30.4) μmol·L^(-1)(p < 0.001), coupled with a significant increase in salivary creatinine from(11.3 ± 5.8) μmol·L^(-1) to(17.0 ± 9.3) μmol·L^(-1)(p = 0.04). In contrast, serum creatine levels were unaffected by exercise(p = 0.80), while creatinine levels exhibited a strong tendency to decrease post-exercise(from [81.8 ±17.5] μmol·L^(-1) to [73.1 ± 11.6] μmol·L^(-1);p = 0.06). A comparison of the slopes of the two regression lines(saliva vs. serum) revealed significant differences for both creatine(p = 0.01) and creatinine(p = 0.03).Conclusions: The above findings suggest a potential difference in the dynamics of creatine metabolites in these two bodily fluids, both pre and post-exercise.

文摘Objectives:To evaluate the occurrence of depression and its related factors among public health nurses(PHNs)engaged in child neglect-related abuse cases.Methods:A cross-sectional study of PHNs involved in maternal and child health or child and family welfare,and engaged in cases of child neglect-related abuse was conducted from January to March 2023 in all municipalities of 13 prefectures selected from Japan's seven regions,considering geographic diversity and major urban areas.The Patient Health Questionnaire-2 was used to screen for depression.Statistical analyses included the Chi-square test,Mann-Whitney U test,and logistic regression analysis.Results:A total of 359 provided valid responses.Among them,11.4%screened positive for depression.Significant individual factors related depression were management-stage nurses(OR=6.27,95%CI:1.63-24.18),no disability welfare experience(OR=3.49,95%CI:1.05-11.55),being assignment of highrisk cases within the past year(OR=8.28,95%CI:2.07-33.08),and lower work control(OR=0.53,95%CI:0.32-0.86).Workplace environment factors were lower perceptions and relationships within the workplace(OR=0.43,95%CI:0.29-0.65)and perceiving manpower as not secured(OR=9.07,95%CI:1.17-70.40),Conclusions:Mental health measures for PHNs should include workload management and reduced burdens through workforce enhancement,attention to burdens on managerial PHNs,promoting communication and mutual support,and opportunities to engage in disability welfare work.
文摘BACKGROUND Given their responsibility for the well-being of individuals,nurses with advanced mental health literacy,along with strong holistic nursing competencies and professional self-efficacy,are better equipped to assess both the mental and physical health of their patients,leading to the provision of holistic nursing care.AIM To investigate the relationship between nurses’mental health literacy levels and their holistic nursing competencies,as well as their nursing professional selfefficacy.METHODS This study is cross-sectional,correlational research.The study sample consisted of a total of 261 volunteer nurses working in a training and research hospital and a state hospital between March 11,2024 and April 8,2024.Data were collected face to face with the“Descriptive Data Form”,“Mental Health Literacy Scale(MHLS)”,“Holistic Nursing Competence Scale(HNCS)”,and the“Nursing Profession Self-Efficacy Scale(NPSES)”.RESULTS The mean scale scores for the nurses were as follows:MHLS:95.88±11.67;HNCS:179.46±33.82;NPSES:64.79±11.24.A low-level positive correlation was found between the total scores of the MHLS,HNCS,and NPSES,and a moderate-level positive correlation was observed between the total scores of the HNCS and NPSES.These correlations were statistically significant(P<0.05).CONCLUSION It is recommended that initiatives be undertaken to enhance the mental health literacy and holistic nursing competencies of nurses and that similar studies be conducted with nurses in different institutions and with a larger number of nurses.
文摘Background:This study examined the development of Tai Chi in Ottawa,Canada,focusing on:(1)traditions and modernization of Tai Chi in China's mainland;(2)the evolution of Ottawa’s Chinese community;and(3)the role of Ottawa Tai Chi Chuan Association(OTCA)and Taoist Tai Chi Society(TTCS)-in promoting Tai Chi and traditional health practices rooted in Traditional Chinese Medicine(TCM)in Ottawa.Methods:Archive research was used to investigate origins,organizational structures,and programs of the associations.Documents were obtained from the personal collections,websites,and Ottawa Archives.Secondary literature on Tai Chi’s history in China and Chinese immigration to Ottawa provided contextual insights.Results:In the twentieth century,Tai Chi in China's mainland underwent significant transformations,aligning with nation-building,social reform,public health promotion,and cultural influence.Since the 1970s,the demographic composition of Canada’s Chinese community has become diversified.Some community members played a critical role in transmitting Tai Chi to Canada by establishing OTCA and TTCS.Through a variety of Tai Chi programs,workshops,and community engagement,OTCA and TTCS promoted Tai Chi as a holistic health practice rooted in TCM and traditional cultural principles in different approaches.OTCA primarily served the Chinese community,focusing on diverse forms,techniques,and theories.In contrast,Ottawa’s TTCS,as a satellite association,emphasized Taoist-inspired Tai Chi and cultivation passed down by the founder,Moy Linshin,to accommodate members from diverse cultural backgrounds.OTCA and TTCS created inclusive mind-body communities for individuals to engage in Tai Chi as a culturally meaningful practice and a means of fostering social connection and holistic wellness.Conclusion:OTCA and TTCS significantly revitalized while adapted Tai Chi and TCM practices to Western contexts,integrating its historical roots with western health ideas to establish it as a widely recognized mind-body discipline and alternative therapy.

文摘Objective:Sick building syndrome(SBS)is a significant health concern among healthcare workers,exacerbated by prolonged exposure to indoor air pollutants and inadequate environmental conditions.Our study aims to explore the prevalence of SBS and its association with indoor air quality and workplace environments among healthcare workers in five hospital departments in Nakhon Si Thammarat,Thailand.Methods:Indoor air quality was assessed over eight days,measuring microbial concentrations(bacteria,fungi),temperature,humidity,and carbon dioxide levels.Demographic data and SBS symptoms were also collected from healthcare workers.Results:The findings revealed that fungal concentrations were highest in the pharmacy(51.95±37.59)colony forming units(CFU)per m^(3),while bacterial concentrations peaked in the outpatient department(265.06±49.46)CFU/m3.The study identified Staphylococcus hominis and Micrococcus luteus as the dominant microbial species in the air environment.A moderate positive correlation was found between bacterial concentrations and humidity(r=0.43,P=0.046).SBS symptoms were prevalent among healthcare workers,with 75.58%reporting issues like dry eyes and fatigue.The total complaint score for SBS correlated positively with indoor pollutant levels,especially fungi(r=0.38,P<0.001).Frequent cleaning reduced SBS complaints significantly(P<0.001).Conclusion:Hospital departments with more frequent cleaning practices exhibited lower SBS complaints,highlighting the importance of cleaning frequency in reducing SBS-related issues.These findings provide actionable insights for improving workplace safety and indoor air quality in healthcare settings.
文摘Introduction: Obstetric Fistulas (OF) constitute a major public health problem in developing countries in general and in Central African Republic (CAR) in particular because of its numerous consequences. The objective of this work is to contribute to the management of OF cases in CAR. Patients and Methods: This was a retrospective, descriptive and analytical study, including data from several OF care services. The study included 245 cases of OF, operated on from 2009 to 2018. The parameters studied were maternal and obstetrical data, sociodemographic data, the specific characteristics of the fistulas as well as the modalities and outcome of surgical treatment. The data collected came from six (6) OF surgical repair campaigns organized by the Ministry of Health and Population with the support of UNFPA. Results: We recorded 245 patients, representing a prevalence of 0.77% of OF per year. Among these patients, almost half (45.3%) were treated at the Sino-Central African Friendship University Hospital Center (CHUASC). The average age of the patients was 30 years (range 14 to 78 years). They were unschooled (53.9%) and primigravidas (35%). The fistulas had an average duration of evolution of 7.58 years. They were vesicovaginal in 25.3%. Types V and I dominated in 17.4% and 9.2%, respectively. In 85.9% of cases, fistulorrhaphy was performed, half of which (50.2%) via the upper route. The cure rate was 83.3%. Note that our study reveals statistically significant links between the evolution after surgery with age (p = 0.04 Conclusion: OF mainly affected women of childbearing age, uneducated, primiparous. Vesicovaginal fistula was the frequently encountered type and was manifested by urine loss clinically with a positive methylene blue test.
文摘Still common in developing countries, acute rheumatic fever (ARF) is not only a disease of children and adolescents, but can also occur in adults. At this age, the diagnosis of rheumatic flare-ups can be difficult due to the frequency of other types of joint diseases and the existence of degenerative and dystrophic valve disease. In adults, the initial rheumatic attack is marked by the predominance of joint damage over cardiac damage. However, it is often at this age that rheumatic valve disease is discovered. The revised Jones criteria also find their place in the diagnosis of AAR in adults. Objective: To study the demographic, clinical, and biological characteristics of acute rheumatic fever (ARF) in the General Medicine Department of the Siguiri Prefectural Hospital. Materials and Methods: This descriptive observational study examined the demographic, clinical and biological characteristics of acute rheumatic fever (ARF) at the Siguiri Prefectural Hospital, Guinea, between April 1 and September 31, 2021 according to Jones criteria. The data were collected on a form containing sociodemographic variables (age, sex, profession), rheumatological, cardiac, pulmonary and neurological clinical signs, biological variables and treatment. Results: Figure 1 shows the flow of the hospital frequency of the RAA in the General Medicine Department of the Prefectural Hospital of Siguiri. During the study period, 420 patients were hospitalized, of whom 161 patients had AAR, a frequency of 38.33%. Table 1 shows the distribution of patients diagnosed with ARB, by sociodemographic characteristics. The average age was 44.7 ± 19.78 years and the extremes of 14 and 90 years, the female sex dominated with a ratio of 0.75. The informal sector was in the majority in 45.34% of cases and most were illiterate, i.e. 53.42%. In our study, the incidence was lower during the dry season than during the rainy season, a hot season with high rainfall and humidity, the rainy period was a provider with a peak in August and September. The lifestyle was characterized by overcrowding in 87.58% of patients. The main complaint was fever, i.e. 88.82%. Rheumatological manifestations such as arthritis were 98.14%, chest pain was 37.89% (61 cases). The diagnosis was confirmed by ASLO titration in 85.71% of patients and 98.55% (136 cases) had a titration greater than 400 U/ml. Conclusion: The results obtained from our study show a high prevalence of acute rheumatic fever, which makes it a worrying health problem in the Siguiri health district. Young female adult patients, married with an informal profession and not in school residing in Siguiri were the most encountered in our study. The main functional signs mentioned by the patients were fever, cough and abdominal pain;osteoarticular pain and chest pain dominated the clinical picture. Almost all of our patients had an ASLO titer greater than 400 U/ml and a positive C-reactive protein. Our results show a high risk of spread of acute rheumatic fever within the population of Siguiri. Due to the serious complications caused by acute rheumatic fever, particular attention must be paid to it by carrying out other, much larger studies in order to identify the problem of RAA.
文摘BACKGROUND The rising global burden of liver diseases,such as non-alcoholic fatty liver disease and liver fibrosis,has necessitated innovative therapeutic approaches.Plant-based therapies,recognized for their anti-inflammatory and antioxidant properties,have shown promising effects.However,poor bioavailability limits their clinical application.AIM To map global research trends,key contributors,and emerging themes in plant-based therapies combined with advanced drug delivery systems for liver health.METHODS Using the Scopus database,645 documents were retrieved and analyzed using bibliometric tools Biblioshiny and VOSviewer.Analysis focused on publication trends,geographical contributions,and advancements in drug delivery technologies,including nanoparticles,liposomes,and polymeric micelles.Metrics such as publication growth rate,authorship collaboration,and thematic clustering were assessed.RESULTS The dataset spans 43 years(1981-2024),with an annual growth rate of 11.09%in the number of publications.Research output is dominated by China(33%),followed by the United States(24%)and India(18%).Collaborative studies accounted for 24.34%of publications,with an average of 5.81 co-authors per document.Key innovations include nanoparticle encapsulation of curcumin and silymarin,improving bioavailability by up to 85%.Highly cited studies demonstrated the antioxidant,anti-inflammatory,and anti-fibrotic properties of these compounds.For instance,curcumin nanoparticles showed a 70%improvement in solubility,and silymarin liposomal formulations enhanced therapeutic efficiency by 62%.Thematic analysis revealed a transition from basic clinical observations to molecular and pharmacokinetic research,with a focus on oxidative stress mitigation and hepatoprotection.CONCLUSION This study highlights the growing synergy between plant-based therapies and advanced drug delivery systems,with significant contributions from Asian and Western countries.Future efforts should prioritize clinical trials,standardization of plant extract formulations,and interdisciplinary approaches to maximize therapeutic outcomes.The findings provide a foundation for integrating plant-derived compounds into evidence-based hepatological therapies,addressing critical challenges in bioavailability and safety.

文摘Background Relative energy deficiency in sport(REDs)results from exposure to problematic low energy availability.It is a serious condition affecting the health and athletic performance of up to 80%of elite female athletes.REDs is established to have negative short-term effects on reproductive function,but the long-term impact of this condition is unknown.Therefore,we examined the impact of secondary amenorrhea with or without a concurrent diagnosis of REDs on perinatal health outcomes.Methods Postpartum individuals(≥18 years of age)completed an online questionnaire that covered demographics,reproductive history(including a diagnosis of REDs or secondary amenorrhea),and maternal/fetal health outcomes.Logistic regression was used to determine the relationship between previously diagnosed REDs or secondary amenorrhea with perinatal health outcomes.Results A total of 1025 previously pregnant participants completed the survey(33.1±3.4 years,mean±SD).Prior to pregnancy,6.1%had been previously diagnosed with REDs and 20.5%had a history with secondary amenorrhea.Individuals diagnosed with REDs had 3.5-times higher odds of having premature labor(odds ratio,(OR)=3.52,95%confidence interval(95%CI):1.26–9.81)and 2.6-times higher odds of preterm delivery(OR=2.62,95%CI:1.05–6.58)compared to those who had not experienced REDs or secondary amenorrhea.However,in individuals who did not have a history of REDs,secondary amenorrhea did not increase the odds of adverse pregnancy or delivery outcomes.Conclusion A history of REDs,but not secondary amenorrhea,may increase the odds of premature labor and preterm delivery.
文摘Background: The irrational use of medicines remains a key health problem in many developing countries. The overuse of antibiotics is a key driver of antimicrobial resistance (AMR). This study surveyed antibiotic use and adherence to the World Health Organization (WHO) prescribing indicators at the Request Muntanga Hospital in the Kalomo District of Southern Province, Zambia. Materials and Methods: This cross-sectional study was conducted from July 2023 to September 2023 at Request Muntanga Hospital in Zambia and reviewed 600 medical record prescriptions which were issued from July 1, 2022 to June 30, 2023 using the WHO prescribing indicators. The collected data were analyzed using Statistical Package for Social Sciences version 23.0. Results: From the 600 prescriptions sampled, 1246 medicines were prescribed, with antibiotics making up 86.7% of the encounters. Additionally, the average number of drugs prescribed per encounter was 2.1 and the prevalence of polypharmacy was 61.3%. Further, 17.8% of medicines were prescribed as injectables. Furthermore, 76.7% of the drugs were prescribed from the Zambia Essential Medicines List and 38.9% by generic names. Conclusions: This study found a high use of antibiotics and deviations from the WHO/International Network of Rational Use of Drugs (INRUD) core prescribing indicators at the Request Muntanga Hospital indicating non-adherence to the prescribing indicators. There is a need to promote adherence to the WHO/INRUD core prescribing indicators to promote the rational use of antibiotics and prevent the emergence and spread of AMR.
文摘In sub-Saharan Africa, foodborne Salmonella infections cause around 680,000 deaths per year. The evolutionary aspects of the incidence of antibiotic resistance in Salmonella strains no longer seem to attract much interest in the Central African Republic (CAR), although salmonellosis remains a health problem requiring national and international surveillance. Methodology: The study conducted at the National Laboratory of Clinical Biology and Public Health, Bangui, Central African Republic (LNBCSP) was a retrospective descriptive study. The study duration was five years (January 2019 to December 2023). The study sample consisted of patients who underwent bacteriological testing of stool, blood and urine samples for Salmonella at the LNBCSP in Bangui during this period. Study variables were age, sex, year and bacteriological test results. Statistical tests were used to compare incidences. Relative risks (RR) were calculated to measure the degree of association. Results: From 2019 to 2023, we recorded 353 Salmonella strains, of which 5% were found in blood, 37% in urine and 58% in stool. Patient age ranged from 1 to 86 years, with a mean of 27 ± 22.05 years and a mode of 5 years. Children aged 0 to 14 years (34%) and females (55.81%) predominated. The highest rate of contamination by Salmonella strains was 1.69% in 2022. The overall incidence of salmonellosis was 6.72 in 2019, 7.05 in 2020, 6.91 in 2021, 16.9 in 2022 and 6.26 in 2023 per 1000 samples. Resistance was 30.47% to β_lactam antibiotics, 24.22% to fluroquinolones and 37.97% to Salmonella spp. For Salmonella arizonae strains, resistance was 20.25% to aminoglycosides, 43.67% to chloramphenicol and 7.59% to imipenem. Conclusion: Laboratory-based surveillance of antibiotic resistance in Salmonella strains is needed in both human and veterinary medicine. Another study based on molecular characterization will identify new antibiotic-resistant variants circulating in CAR.
文摘This study compared the acute effects of electrical energy transfer(TECAR) and transcutaneous electrical stimulation(TENS) on pain and flexibility after a hamstring injury. Young athletes received either a 20 min TECAR(n = 24) or TENS(n = 26) session within 5 days following a hamstring injury, while the control(CON, n = 25)group was instructed to rest. Visual analogue scale(VAS), functional Assessment Scale for Acute Hamstring Injuries(FASH), straight leg raise test(SLR), and sit-and-reach scores(STR) were obtained prior to, immediately,24, and 48 h after therapy. Group differences were detected after therapy in VAS and FASH scores(p < 0.05).Compared to pre-therapy measurements, VAS scores showed a greater decrease in the TECAR group(-38.75% to-63.33%) than in the TENS group(-16.67% to-25.00%) and both were greater than in the CON group(-2.81%to-9.81%)(p < 0.05). The TECAR group improved FASH scores(28.57%–48.21%) more than the TENS group(15.89%–27.79%) and both groups more than the CON group(0%–8.33%)(p < 0.05). The increase in SLR and STR was greater in the TECAR group(6.26%–13.96%) than in the TENS(1.72%–9.53%) and CON groups(0%–3.03%). These results suggest that in the acute phase of hamstring injury, the use of TECAR and, to a lesser extent, TENS may relieve pain symptoms and bring some improvements in flexibility more than instructing patients to rest.

文摘Drug development for Alzheimer’s disease is extremely challenging,as demonstrated by the repeated failures of amyloid-β-targeted therapeutics and the controversies surrounding the amyloid-βcascade hypothesis.More recently,advances in the development of Lecanemab,an anti-amyloid-βmonoclonal antibody,have shown positive results in reducing brain A burden and slowing cognitive decline in patients with early-stage Alzheimer’s disease in the Phase Ⅲ clinical trial(Clarity Alzheimer’s disease).Despite these promising results,side effects such as amyloid-related imaging abnormalities(ARIA)may limit its usage.ARIA can manifest as ARIA-E(cerebral edema or effusions)and ARIA-H(microhemorrhages or superficial siderosis)and is thought to be caused by increased vascular permeability due to inflammatory responses,leading to leakages of blood products and protein-rich fluid into brain parenchyma.Endothelial dysfunction is an early pathological feature of Alzheimer’s disease,and the blood-brain barrier becomes increasingly leaky as the disease progresses.In addition,APOE4,the strongest genetic risk factor for Alzheimer’s disease,is associated with higher vascular amyloid burden,increased ARIA incidence,and accelerated blood-brain barrier disruptions.These interconnected vascular abnormalities highlight the importance of vascular contributions to the pathophysiology of Alzheimer’s disease.Here,we will closely examine recent research evaluating the heterogeneity of brain endothelial cells in the microvasculature of different brain regions and their relationships with Alzheimer’s disease progression.

文摘Background:The mechanisms underlying the beneficial effects of exercise on the human placenta are poorly understood.The objective of the current study was to ascertain the influence of a supervised concurrent exercise intervention from gestational Week 17 until birth on key cytokines involved in placental development and function.Secondary aims were to explore:(a)the moderating effects of fetal sex and maternal weight status;and(b)whether gestational weight gain,lifestyle behaviors(diet,sleep patterns,and physical activity),and physical fitness(strength and cardiorespiratory fitness)mediated the effects of exercise on placental cytokines.Methods:Seventy-six pregnant women(33±4 years,mean±SD),divided into exercise(n=40)and control(n=36)groups,participated in this study.The exercise group followed a 60-min,3 days/week(aerobic+resistance)training program of moderate-to-vigorous intensity.Placental cytokines—including granulocyte-macrophage colony-stimulating factor(GM-CSF),granulocyte colony-stimulating factor(G-CSF),plateletderived growth factor AA(PDGF-AA),epidermal growth factor(EGF),monocyte chemoattractant protein-1(MCP-1),fractalkine,interleukin(IL)-8,IL-6,IL-1β,interleukin 1-receptor antagonist(IL-1ra),IL-10,tumor necrosis factor alpha(TNF-a),and interferon gamma(IFN-γ)were analyzed using Luminex multi-analyte profiling(x MAP)technology.Results:The exercise group presented higher placental levels of G-CSF and lower concentrations of EGF and IL-1ra than the control group(p<0.05).Significant effects of exercise on placental G-CSF and TNF-a(p<0.05)and a trend toward lower IL-6(p=0.08)were observed only in female placentas.Additionally,a reduction in weight gain partially mediated the effects of exercise on G-CSF(p<0.05).Conclusion:Maternal exercise during pregnancy is related to increased placental levels of G-CSF and lower EGF and IL-1ra levels.Some exercise-induced effects are observed exclusively in female placentas,including increased G-CSF and lower TNF-a and IL-6 concentrations.Notably,the increased levels of G-CSF observed with exercise might be due to a more adequate gestational weight gain.
文摘Background:Insufficient physical activity and prolonged sedentary behavior have emerged as major global public health challenges.Short bouts(≤10 min)of accumulated exercise(SBAE)throughout the day may be a promising strategy to mitigate the adverse effects of prolonged sitting and promote physical activity,ultimately promoting overall health.However,previous ambiguity in defining this concept has resulted in a fragmented and inconsistent evidence base,impeding practical applications,the development of guidelines,and policymaking.The purpose of this study is to establish an operational definition of SBAE by synthesizing systematic reviews and research trials alongside an expert consensus.Additionally,it seeks to evaluate acute and long-term efficacy and feasibility,providing evidence-based recommendations for practice and future research directions.Methods:A literature search was performed across PubMed and Web of Science,followed by systematic screening and summarization of eligible studies based on predefined inclusion criteria.Inclusion criteria encompassed various modes/types of SBAE(bouts lasting≤10 min,performed multiple times daily with≥30 min intervals);both aerobic and resistance exercise were considered.Relevant systematic reviews and research trials were included.Methodological quality,risk of bias,and evidence certainty were assessed.Expert consensus was obtained through a survey to evaluate recommendations and agreement levels on findings.Results:After analyzing 27 systematic reviews,135 research studies,and an expert consensus involving 48 researchers from 11 countries,SBAE is defined as any exercise mode of activity,regardless of intensity,that is accumulated in either continuous or intermittent bouts lasting≤10 min per session(including multiple intermittent sets)that are performed multiple times(≥2 sessions/day)per day,with intervals of≥30 min between bouts or otherwise sufficient time for recovery.When used to interrupt prolonged periods of sedentary time,SBAE mitigates the acute adverse effects of sedentary behavior on more than 10 clinical biomarkers of endocrine,cardiovascular,and brain health/function among adults of diverse ages and conditions.Moreover,SBAE was superior for improving acute glycemic control compared to a single continuous exercise session.As a long-term intervention(average of 11 weeks),SBAE can improve over 20 health outcomes,including peak oxygen uptake,resting blood pressure,and metabolic health.Additionally,SBAE might be more effective than continuous exercise for improving longer-term glycemic control and body composition.Long-term completion rates for SBAE interventions are generally high(95%),with low dropout rates(12%)and high adherence rates even without supervision(85%),and its safety has been preliminarily validated.Conclusion:An operational definition of SBAE is provided along with its classification and acute and long-term efficacy.Practical exercise prescription recommendations and evidence-based strategies for various populations and contexts are provided.Future research should focus on generating high-quality evidence for SBAE in 5 key areas:quantification and monitoring,population-specific responses,optimization of exercise prescriptions,intervention efficacy,and practical implementation.Additionally,addressing policy,environmental,and promotional barriers is crucial for transitioning from expert consensus to public consensus,and for facilitating the application of this strategy in real-world environments.

文摘Background:Investigators from low-,middle-,and high-income countries representing 6 continents contributed to the development of the Global Adolescent and Child Physical Activity Questionnaire(GAC-PAQ).The GAC-PAQ is designed to assess physical activity(PA)across all key domains(i.e.,school,chores,work/volunteering,transport,free time,outdoor time).It aimed to address multiple gaps in global PA surveillance(e.g.,omission of important PA domains,insufficient cultural adaptation,underrepresentation of rural areas in questionnaire validation studies).The purpose of this study was to assess the content validity of the GAC-PAQ among PA experts,8-to 17-year-olds,and one of their parents/guardians,and to discuss changes made to the questionnaire based on participants'feedback.Methods:Sixty-two experts in PA measurement and/or surveillance from 24 countries completed an online survey that included both closed-and open-ended questions about the content validity of the GAC-PAQ.The proportion of experts who agreed or strongly agreed with the items was calculated.Child-parent/guardian dyads from 15 countries(n=250;10-40 per country)participated in a structured cognitive interview to assess the clarity of the questions and response options,and they were encouraged to provide suggestions to improve clarity and facilitate completion of the questionnaire.Participating countries are:Aotearoa New Zealand,Brazil,Canada,China,Colombia,Czech Republic,India,Malawi,Mexico,Nepal,Nigeria,Spain,Sweden,Thailand,and the United Arab Emirates.Interviews were conducted in 13 different languages and structured by PA domain.Generic images were included to help participants in answering questions about PA intensity.Results:Expert agreement with the items for each domain exceeded 75%,and their qualitative feedback was used to revise the questionnaire before cognitive interviews.In general,participants found the questionnaire to be comprehensive.Adolescents(12-17 years)found it easier than children(8-11 years)to answer the questions.Several children struggled to answer questions about the duration and intensity of activities and/or concepts related to travel modes,active trips,and organized activities.Many parents/guardians were unsure about the frequency,duration,and intensity of their children's or adolescents'PA at school and/or recommended using more culturally relevant and appropriate images.Some participants misunderstood the concept of activities that“make you stronger”(intended to assess resistance activities)and/or struggled to differentiate between work,volunteering,and chores.Conclusion:Participants'feedback was used to develop a revised,simplified,and culturally adapted GAC-PAQ,which will be pilot-tested in all15 countries in an App that will include country-specific images and narration in local languages.Further research is needed to assess the reliability and validity of the revised GAC-PAQ.
