Pooled odds ratio, mean difference or standardized mean difference, and its corresponding 95% confidence interval were calculated with the Cochrane Review Manager 5.3.Results: A significantly lower vitamin D level was found in TB patients vs controls; vitamin D deficiency (VDD) was associated with an increased risk of TB, although such an association was lacking in the African population and in the human immunodeficiency virus-infected African population. A significantly lower vitamin D level was found in human immunodeficiency virus-TB-coinfected African patients receiving antiretroviral treatment who developed TB-associated immune reconstitution inflammatory syndrome vs those who did not develop TB-associated immune reconstitution inflammatory syndrome. VDD was associated with an increased risk of developing active TB in those subjects with latent TB infection and with an increased risk of tuberculin skin test conversion/TB infection conversion, and the trend toward a lower vitamin D level in active TB patients vs latent TB infection subjects did not reach statistical significance, indicating that VDD was more likely a risk factor than a consequence of TB. This concept was further strengthened by our result that anti-TB treatment did not affect vitamin D level in TB patients receiving the treatment.Conclusion: Our analyses revealed an association between vitamin D and TB. VDD is more likely a risk factor for TB than its consequence. More studies are needed to determine whether vitamin D supplementation is beneficial to TB prevention and treatment.

Fibroblast growth factor 23 (FGF23) was identified at the turn of the century as the long-sought circulating phosphatonin in human pathology. Since then, several clinical and experimental studies have investigated the metabolism of FGF23 and revealed its relevant pathogenic role in various diseases. Most of these studies have been performed in adult individuals. However, the mineral metabolism of the child is, to a large extent, different from that of the adult because, in addition to bone remodeling, the child undergoes a specific process of endochondral ossification responsible for adequate mineralization of long bones’ metaphysis and growth in height. Vitamin D metabolism is known to be deeply involved in these processes. FGF23 might have an influence on bones’ growth as well as on the high and age-dependent serum phosphate concentrations found in infancy and childhood. However, the interaction between FGF23 and vitamin D in children is largely unknown. Thus, this review focuses on the following aspects of FGF23 metabolism in the pediatric age: circulating concentrations’ reference values, as well as those of other major variables involved in mineral homeostasis, and the relationship with vitamin D metabolism in the neonatal period, in vitamin D deficiency, in chronic kidney disease (CKD) and in hypophosphatemic disorders.

Existing literature on school counseling site supervision has implications for its continuous improvement. Most local studies have focused on the perspectives of supervisees and with participants coming from Metro Manila only. In order to provide a clearer understanding of what happens in school counseling site supervision, the present study employed a descriptive phenomenological approach to explore the lived experiences of Filipino guidance counselors as school counseling site supervisors. Twelve (12) Filipino guidance counselors from Luzon, Visayas, and Mindanao, recruited through purposive sampling, were virtually interviewed using an interview guide that was content validated by experts prior to utilization. Results revealed six (6) emerging themes: Assignment as Site Supervisor, Affirming Experiences, Challenges Encountered, Different Supervision Practices, Supervisor Preparation and Development, and Supervision Advocacies. Results may serve as a resource for site supervisors and counselor educators to improve practice.

BACKGROUND AND OBJECTIVE: Systemic lupus disorder is a heterogeneous autoimmune disease that can affect any organ of the body. Leptin affects the activation, differentiation and proliferation of immune cells. This study aimed to evaluate the serum level of leptin and its relationship with disease activity and some inflammatory factors in women with systemic lupus erythematosus (SLE). METHODS: In this cross-sectional study, 40 women with SLE who were admitted to the rheumatology ward of Urmia Imam Khomeini Hospital during the second semester of 2017 and 40 healthy controls were enrolled. Serum leptin concentration was measured by sandwich ELISA method in two groups. In SLE patients the disease activity was calculated using Systematic lupus erythematous activity index (SLEDAI). Inflammatory factors including CRP (C-reactive protein) and ESR (Erythrocyte Sedimentation Rate) were extracted from the patient's records at the time of admission. FINDINGS: Serum leptin level was significantly different in patients (44.51±25.6) and controls (22.37±12.58) (p

(1) Background: The COVID-19 pandemic and the implementation of restrictions and nonpharmaceutical interventions (NPIs) changed the trends in respiratory viral circulation and the pattern in pediatric healthcare utilization; (2) Methods: A retrospective, multicenter observational study designed to analyze the impact of the pandemic on pediatric healthcare utilization and the viral circulation pattern in children in a region in Northern Spain was carried out. Viral diagnostics data from all nasal or pharyngeal swabs collected in children in Asturias during the periods of March 2018–September 2019 and March 2020–September 2021 were analyzed, as well as the number of pediatric hospitalizations and emergency visits; (3) Results: A total of 14,640 samples were collected during the pandemic period. Of these, at least one respiratory virus was detected in 2940 (20.1%) while 5568/10,298 samples were positive in the pre-pandemic period (54.1%); p < 0.001. The detection of both enveloped and non-enveloped viruses decreased among periods (p < 0.001). After week 14, 2020, enveloped viruses were no longer detected until one year later, while non-enveloped viruses continued to be detected in children. Overall, a mean of 4946.8 (95% CI 4519.1–5374.4) pediatric emergency visits per month during the period 2018–2019 as compared to 2496.5 (95% CI 2086.4–2906.5) for 2020–2021 occurred (p < 0.001). The mean of pediatric hospitalizations also significantly decreased between periods, as follows: 346.6 (95% CI 313–380.2) in 2018–2019 vs. 161.1 (95% CI 138.4–183.8); p < 0.001; (4) Conclusions: Our study showed a remarkably reduction in pediatric hospitalizations and emergency visits and a change in the pattern of viral circulation during the COVID-19 pandemic in Asturias. The usual seasonal respiratory viruses, namely influenza or RSV were nearly absent in the pediatric population during the pandemic.

Background: Anemia is a major nutrition related problem in China. In addition to iron deficiency this may be due to deficiencies of other micronutrients. Objective: To describe the micronutrient status of anemic and non-anemic pregnant women in China. Subjects and Methods: 734 clinically normal pregnant women in the third trimester aged 20-35, were randomly recruited from the population of pregnant women regularly receiving pregnant examination in community medical centers. Serum concentrations of vitamins A, B12 and C, iron and zinc status parameters, and vitamin B2 in urine were determined. Subjects were categorized according to the presence or absence of anemia and compared according to micronutrient status. Results: Serum concentrations of iron and micronutrients were significantly lower in anemic women than non-anemic women: serum iron 909 mug/L versus 1109 mug/L, ferritin 13.8 mug/L versus 19.6 mug/L, vitamin C 308.9 mug/L versus 388.1 mug/dL, and retinol 50.0 mug/dL versus 59.3 mug/dL. Zinc concentrations were also lower in anemic women. Subnormal serum iron (<700 mug/L) and iron depletion (ferritin <12 mug/L) were 39.7% and 52.6%, significantly more frequent in anemic than 23.9% and 35.0% in non-anemic subjects, as were subnormal vitamin A and ascorbic acid. Subnormal vitamin B2 and B12 were frequent in both anemic and non-anemic groups. Conclusion: Subnormal concentrations of iron and micronutrients in combination may contribute to this situation. Further studies on food-based or supplement-based approaches trying to increase intake of iron and certain vitamins are warranted to decrease anemia in pregnant Chinese women in the third trimester.

Objectives: This study, developed within the Innovative Medicines Initiative Joint Undertaking project PRECISESADS framework, aimed at functionally characterize the monocyte subsets in RA patients, and analyze their involvement in the increased CV risk associated with RA.Methods: The frequencies of monocyte subpopulations in the peripheral blood of 140 RA patients and 145 healthy donors (HDs) included in the PRECISESADS study were determined by flow cytometry. A second cohort of 50 RA patients and 30 HDs was included, of which CD14+ and CD16+ monocyte subpopulations were isolated using immuno-magnetic selection. Their transcriptomic profiles (mRNA and microRNA), proinflammatory patterns and activated pathways were evaluated and related to clinical features and CV risk. Mechanistic in vitro analyses were further performed.Results: CD14++CD16+ intermediate monocytes were extended in both cohorts of RA patients. Their increased frequency was associated with the positivity for autoantibodies, disease duration, inflammation, endothelial dysfunction and the presence of atheroma plaques, as well as with the CV risk score. CD14+ and CD16+ monocyte subsets showed distinctive and specific mRNA and microRNA profiles, along with specific intracellular signaling activation, indicating different functionalities. Moreover, that specific molecular profiles were interrelated and associated to atherosclerosis development and increased CV risk in RA patients. In vitro, RA serum promoted differentiation of CD14+CD16− to CD14++CD16+ monocytes. Co-culture with RA-isolated monocyte subsets induced differential activation of endothelial cells.Conclusions: Our overall data suggest that the generation of inflammatory monocytes is associated to the autoimmune/inflammatory response that mediates RA. These monocyte subsets, -which display specific and distinctive molecular signatures- might promote endothelial dysfunction and in turn, the progression of atherosclerosis through a finely regulated process driving CVD development in RA.

OBJECTIVE:To assess if serum free 25-hydroxyvitamin D (25OHD) is a better indicator of vitamin D status than total 25OHD in healthy children. METHODS:Cross-sectional prospective clinical study was designed. We measured serum free 25OHD concentrations and its correlation with calculated free 25OHD, total 25OHD, intact parathyroid hormone (PTH), and vitamin D binding protein (DBP) in children. The influence of age, sex, ethnicity, body mass index (BMI), season of the year, diet intake, vitamin supplements, time spent outdoors and albumin concentrations on free 25OHD was also analyzed. 241 children aged from 0 days to 14 years, and living in the northern Spain (latitude 43° N), were included. RESULTS:Mean (SD) free 25OHD concentrations were 2.48 (1.39), 5.46 (3.12), 4.12 (1,72), 3.82 (1.43) pg/ml in children aged 0 days, 1 month-2 years, 2-6 years and >6 years, respectively. Correlation between directly measured and calculated free 25OHD was high and significant (r = 0.66) as well as the correlation between serum free and total 25OHD concentrations (r = 0.61). No significant correlation was found between PTH and free 25OHD (r = -0.08). The total 25OHD and PTH concentrations' correlation was inverse (r = -0.25) and significant. Neither free nor total 25OHD concentrations correlated with DBP concentrations. Among the analyzed variables, free 25OHD values were higher in spring/summer than in autumn/winter in children older than 6 years. CONCLUSIONS:: These findings do not support that free 25OHD is a better marker of vitamin D deficiency than total 25OHD in healthy pediatric population.

Accurate measurement of physical performance in individuals with musculoskeletal pain is essential. Accelerometry is a powerful tool for this purpose, yet the current methods designed to evaluate energy expenditure are not optimized for this population. The goal of this study is to empirically derive a method of accelerometry analysis specifically for musculoskeletal pain populations.We extracted data from 6,796 participants in the 2003-4 National Health and Nutrition Examination Survey (NHANES) including: 7-day accelerometry, health and pain questionnaires, and anthropomorphics. Custom macros were used for data processing, complex survey regression analyses, model selection, and statistical adjustment. After controlling for a multitude of variables that influence physical activity, we investigated whether distinct accelerometry profiles accompany pain in different locations of the body; and we identified the intensity intervals that best characterized these profiles.Unique accelerometry profiles were observed for pain in different body regions, logically clustering together based on proximity. Based on this, the following novel intervals (counts/minute) were identified and defined: Performance Sedentary (PSE) = 1-100, Performance Light 1 (PL1) = 101-350, Performance Light 2 (PL2) = 351-800, Performance Light 3 (PL3) = 801-2500, and Performance Moderate/Vigorous (PMV) = 2501-30000. The refinement of accelerometry signals into these new intervals, including 3 distinct ranges that fit inside the established light activity range, best captures alterations in real-life physical performance as a result of regional pain.These new accelerometry intervals provide a model for objective measurement of real-life physical performance in people with pain and musculoskeletal disorders, with many potential uses. They may be used to better evaluate the relationship between pain and daily physical function, monitor musculoskeletal disease progression, gauge disease severity, inform exercise prescription, and quantify the functional impact of treatments. Based on these findings, we recommend that future studies of pain and musculoskeletal disorders analyze accelerometry output based on these new "physical performance" intervals.

Abstract Introduction:More than 8-12% of healthy people suffered from sleep disorders worldwide. This problem evaluated among guards in a little past studies. We aimed to assess this defect among hospital guards of Iran university of Medical Sciences. Materials: 74 guards filled out two different questionnaires aboutsleep quality, ESS and PSQI. Demographic data were obtained based on another self-designed questionnaire. Results:All data were analyzedand scores of the questionnaires were compared among guards of different wards. The urgencyguards of Rasul e Akram hospital reflected more disorders than the other groups. Marriage state wasaffected on final results, despite cigarette smoking and obesity had shown no significantly effects. Conclusion: Sleep hygiene may have a trouble situation among guards and modification of the sleep habit could improve the majority of the disorder. -

Introduction: The rational use of medicines is essential for preventing adverse medicine reactions, achieving therapeutic outcomes, and optimizing treatment costs. While the irrational use of medicines is frequently reported in sub-Saharan Africa, to the best of our knowledge no formal studies have taken place in Mauritania thus far. The main objective of this study was therefore to analyze the rational use of medicines in public and private not-for-profit health facilities, in five health districts in Mauritania., Methods: We conducted a cross-sectional study to assess the rational use of medicines. We used the standard indicators derived from the methodologies of the World Health Organization (WHO) and International Network for Rational Use of Drugs (INRUD). Data were prospectively collected from 1050 prescriptions/patients, in thirty-one public and private not-for-profit health posts/centers in 5 health districts. The data were analyzed using the Statistical Package for the Social Sciences. P value less than 0.05 at 95% confidence interval considered for significance of relationships for associations in statistical test., Results: The average number of medicines per prescription was 2.21; 83.1% (1931/2325) of medicines were prescribed by generic name, but only 54% (1253/2325) were on the National Essential Medicine List (NEML). Antibiotics were prescribed in 62.4% (655/1050) of the consultations, and injectable medicines were prescribed in 15.6% (164/1050) of the consultations. The average consultation time was 16.32 minutes, and the average dispensing time was 97 seconds. Dispensed medicines were correctly labeled, and 83% (871/1050) of patients met the correct administration schedule. The NEML, and the "restricted NEML" for 76 commonly-used medicines, were available in all surveyed health facilities, but the National Therapeutic Guidelines were available in only 60.26% of them., Conclusion: Our findings indicate a possible excess of antibiotics prescriptions, and a likely lack of knowledge of the National Therapeutic Guidelines. There is a need to investigate in more detail the prescription patterns versus disease-specific therapeutic guidelines, and to qualitatively investigate the factors that contribute to the observed irrational prescribing. Moreover, training local staff in the rational use of medicines seems important., Competing Interests: Dr Mohamed Ali Ag Ahmed reports personal fees, non-financial support from Institute of Tropical Medicine Antwerp, outside the submitted work.

Background: Digital health technologies (DHTs) are promoted as means to reduce the environmental impact of healthcare systems. However, a growing literature is shedding light on the highly polluting nature of the digital industry and how it exacerbates health inequalities. Thus, the environmental footprint of DHTs should be considered when assessing their overall value to healthcare systems. The objectives of this article are to: (1) explore stakeholders' perspectives on integrating the environmental impacts of DHTs in assessment and procurement practices; (2) identify the factors enabling or constraining the operationalisation of such a change; and (3) encourage a constructive dialogue on how environmental issues fit within healthcare systems' push for more DHTs., Methods: Semi-structured interviews were conducted with 29 stakeholders involved in DHTs in a large Canadian academic healthcare centre. Data were collected and analysed through a mixed deductive-inductive process using a framework derived from diffusion of innovations theories., Results: The integration of the environmental impact of DHTs in assessment and procurement is contingent upon key micro-meso-macrosystemic factors that either enable or constrain changes in practices and processes. Innovation (micro) factors include stakeholders' recognition of the environmental issue and the extent to which it is feasible for them to address the environmental impact of DHTs. Organisational (meso) factors include the organisation's culture, leadership, policies, and practices, as well as the expertise and professional skillsets available. Finally, external (macro) factors include political and regulatory (e.g., national strategy, laws, standards, norms), economic (e.g., business models, public procurement), and professional and scientific factors (e.g., evidence, methodologies, clinical guidelines)., Conclusion: Considering the environmental impact of DHTs depends on micro-meso-macrosystemic factors involving a variety of stakeholders and levels of governance, sometimes with divergent or even antagonistic objectives and expectations. It highlights the importance of better understanding the complexity inherent in the environmental shift in healthcare., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

Introduction: A country's ability to manage a crisis depends on its level of resilience. Efforts are made to clarify the concept of health system resilience, but its operationalisation remains little studied. In the present research, we described the capacity of the local healthcare system in the Islamic Republic of Mauritania, in West Africa, to cope with the COVID-19 pandemic., Methods: We used a single case study with two health districts as units of analysis. A context analysis, a literature review and 33 semi-structured interviews were conducted. The data were analysed using a resilience conceptual framework., Results: The analysis indicates a certain capacity to manage the crisis, but significant gaps and challenges remain. The management of many uncertainties is largely dependent on the quality of the alignment of decision-makers at district level with the national level. Local management of COVID-19 in the context of Mauritania's fragile healthcare system has been skewed to awareness-raising and a surveillance system. Three other elements appear to be particularly important in building a resilient healthcare system: leadership capacity, community dynamics and the existence of a learning culture., Conclusion: The COVID-19 pandemic has put a great deal of pressure on healthcare systems. Our study has shown the relevance of an in-depth contextual analysis to better identify the enabling environment and the capacities required to develop a certain level of resilience. The translation into practice of the skills required to build a resilient healthcare system remains to be further developed., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Introduction: The COVID-19 pandemic has exacerbated an already existing security crisis leading to massive population displacements that have been taking place since 2012., Purpose of Research: This study aims to explore the representations of internally displaced persons (IDPs) about the existence of COVID-19 and their knowledge about its signs, symptoms, modes of transmission and prevention measures., Methods: The study was qualitative and exploratory. Individual and group interviews were used to collect data from 52 IDPs in six sites in Bamako and Segou. All interviews were recorded and transcribed. Thematic content analysis and N-Vivo software were used., Results: The majority of IDPs believed in the existence of COVID-19 and had good knowledge of the signs, symptoms, modes of transmission and prevention measures against the disease. However, this was not sufficient for the adoption of public health measures. Among those who believed in its existence, some thought that it was a disease of the white and rich. Finally, a group of participants believed in conspiracy theories and claimed that the government and humanitarian organizations were only trying to make money through these campaigns., Conclusion: To our knowledge, this is the first study in Mali to explore IDPs’ beliefs and knowledge about COVID-19. These results could inform policies, strategies, and interventions to combat COVID-19 in IDP sites and in the general population.

Background: Underlying inflammation is associated with an increased risk of depression in older adults. In this study, we examined the role of inflammatory biomarkers in antidepressant response in depressed older adults undergoing adjunct Tai Chi Chih (TCC) or Health education interventions., Methods: Older adults aged 60 years and above with a diagnosis of major depression were randomized to 12 weeks of TCC versus Health and Wellness Education (HEW) as an adjunct therapy to their stable antidepressant treatment regimen. A panel of 19 cytokine/chemokines was measured at baseline and 12 weeks. Five factors were derived using factor analysis. General linear models were estimated to examine the change in factor scores and the association of these changes on depression remission rates, controlling for age, sex, and body mass index., Results: Of the 170 randomized participants (TCC: n = 85 and HEW: n = 85), 55 TCC and 58 HEW completed the 3-month assessment. The groups did not differ at baseline in any measure. At follow-up, neither the changes in cytokine/chemokines scores nor the depression remission rate differed significantly between TCC and HEW. However, remitters and non-remitters differed significantly in changes in a factor composed of growth-regulated oncogene protein-alpha (GRO-alpha), epidermal growth factor (EGF), and soluble CD40 ligand (sCD40L). GRO-alpha and EGF levels (in both groups) were significantly increased in remitters compared to non-remitters., Conclusion: Changes in certain cytokines/chemokines may accompany improvement in depressive symptoms in older adults. Future studies will need to explore the role of these molecules in remission of late-life depression., (Copyright © 2022 American Association for Geriatric Psychiatry. Published by Elsevier Inc.

Toxoplasmosis is defined as a cosmopolitan protozoan disease caused by an obligate intracellular coccidia, Toxoplasma gondii . The advent of HIV infection has made cerebral toxoplasmosis one of the most widespread neurological opportunistic infections., Method: We conducted a descriptive cross-sectional study with retrospective review of files of cerebral toxoplasmosis on HIV infected patients who had been hospitalized in the infectious diseases department of Point G University Hospital between January 1 st , 2014 and September 30 th , 2019., Results: During the study period, the frequency of cerebral toxoplasmosis was 10.1% and in 46.4% of the patients, the diagnosis led to the discovery of HIV co-infection. The clinical features were characterized by fever, headaches, and motor deficit at 86.6%, 84.5% and 69.1% respectively. Roundel image on computed tomography was most represented and was found in 24.4% of patients. Anti-toxoplasma treatment based on trimethoprim /sulfamethoxazole (TMP/SMX) associated with folinic acid was initiated in 78 patients out of 90, but 19 patients had a contraindication or adverse effects to this combination and were treated with clindamycin. HAART was initiated in 31 patients out of 45 (68.9%) newly diagnosed. The overall prognosis was limited with a mortality rate of 42%., Conclusion: The prevalence of cerebral toxoplasmosis was high in our study, 10.1%. To reduce this prevalence, chemoprophylaxis should be initiated in all HIV-infected patients with a CD4 count below 200 cells/mm3., (Le comité de rédaction se réserve le droit de renvoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.

Background: For almost a decade now, Mali has been facing a security crisis that led to the displacement of thousands of people within the country. Since March 2020, a health crisis linked to the COVID-19 pandemic also surfaced. To overcome this health crisis, the government implemented some physical distancing measures but their adoption proved difficult, particularly among internally displaced people (IDPs). The objective of this study is to identify the challenges relating to the implementation and adoption of physical distancing measures and to determine the main mitigation measures taken by IDPs to adjust to these new policies., Methods: An exploratory qualitative research was conducted in Bamako and Ségou, two of the ten regions of Mali. The study counted 68 participants including 50 IDPs, seven administrative and health authorities, and 11 humanitarian actors. Sampling was guided by the principle of saturation and diversification, and data was collected through semi-structured individual interviews (n = 36) and focus groups (n = eight). Analysis was based on thematic content analysis through NVivo software., Results: The main challenges identified concerning the implementation and adoption of physical distancing measures include the proximity in which IDPs live, their beliefs and values, the lack of toilets and safe water on sites, IDPs habits and economic situation, humanitarian actors' lack of financial resources and authority, and social pressure from religious leaders. Implemented mitigation measures include the building of new shelters or their compartmentalization, the creation of income-generating activities and food banks, psychosocial support, promoting awareness of IDPs, and nightly police patrols and surveillance to discourage IDPs from going out. Finally, a call for action is suggested for the actors involved in IDPs support and management., Conclusions: The study demonstrates the difficulty for IDPs to follow most of the physical distancing measures and informs about the risk of disease spreading among IDPs with its potential consequences. It also shows the inability of mitigation measures to control the outbreak and suggests actions to be considered., (© 2021. The Author(s).)

Objective: To determine whether B vitamin treatment was sufficient to reduce cognitive impairment associated with high-fat diets in rats and to modulate transketolase (TK) expression and activity., Methods: To test this, we separated 50 rats into five groups that were either fed a standard chow diet (controls) or a high-fat diet (experimental groups H0, H1, H2, and H3). H0 group animals received no additional dietary supplementation, while H1 group animals were administered 100 mg/kg body weight (BW) thiamine, 100 mg/kg BW riboflavin, and 250 mg/kg BW niacin each day, and group H2 animals received daily doses of 100 mg/kg BW pyridoxine, 100 mg/kg BW cobalamin, and 5 mg/kg BW folate. Animals in the H3 group received the B vitamin regimens administered to both H1 and H2 each day., Results: Over time, group H0 exhibited greater increases in BW and fat mass relative to other groups. When spatial and memory capabilities in these animals were evaluated via conditioned taste aversion (CTA) and Morris Water Maze (MWM), we found B vitamin treatment was associated with significant improvements relative to untreated H0 controls. Similarly, B vitamin supplementation was associated with elevated TK expression in erythrocytes and hypothalamus of treated animals relative to those in H0 (P<0.05)., Conclusion: Together, these findings suggest B vitamin can modulate hypothalamic TK activity to reduce the severity of cognitive deficits in a rat model of obesity. As such, B vitamin supplementation may be a beneficial method for reducing cognitive dysfunction in clinical settings associated with high-fat diets., (© 2021.

Objective: A patient-centred care interdisciplinary pragmatic intervention to support self-management for patients with multimorbidity was implemented in one region of Quebec, Canada. This embedded study aimed to evaluate the process of implementation., Design: A descriptive qualitative study was conducted in 2016-2017 using semistructured individual interviews. The Consolidated Framework for Implementation Research (CFIR) was used to guide the data coding, analysis and reporting of the findings., Setting: The study took place in seven Family Medicine Groups in one region (Saguenay-Lac-Saint-Jean) of Quebec, Canada., Participants: Ten managers (including two family physicians) and 19 healthcare professionals (HCPs), nurses, kinesiologists, nutritionists and a respiratory therapist, were interviewed., Results: Many key elements within the five CFIR domains were identified as impacting the implementation of the intervention : (1) intervention characteristics-evidence strength and quality, design quality and packaging, relative advantage and complexity; (2) outer setting-patients' needs and resources, external policies and incentives; (3) inner setting-structural characteristics, networks and communication, culture, compatibility, readiness for implementation and leadership engagement; (4) characteristics of the managers and HCPs-knowledge and belief about the intervention; (5) process-planning, opinion leaders, formally appointed internal implementation leaders, reflecting and evaluating., Conclusion: This study revealed the organisational and contextual aspects of the implementation based on different and complementary perspectives. With the growing demand for interdisciplinary teams in primary care, we believe that our insights will be helpful for practices, researchers, and policymakers interested in the implementation of disease prevention and management programmes for people with multiple chronic conditions in primary care., Trial Registration Number: NCT02789800., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

The magnitude of the COVID-19 pandemic challenged societies around our globalized world. To contain the spread of the virus, unprecedented and drastic measures and policies were put in place by governments to manage an exceptional health care situation while maintaining other essential services. The responses of many governments showed a lack of preparedness to face this systemic and global health crisis. Drawing on field observations and available data on the first wave of the pandemic (mid-March to mid-May 2020) in Quebec (Canada), this article reviewed and discussed the successes and failures that characterized the management of COVID-19 in this province. Using the framework of Palagyi et al. on system preparedness toward emerging infectious diseases, we described and analyzed in a chronologically and narratively way: (1) how surveillance was structured; (2) how workforce issues were managed; (3) what infrastructures and medical supplies were made available; (4) what communication mechanisms were put in place; (5) what form of governance emerged; and (6) whether trust was established and maintained throughout the crisis. Our findings and observations stress that resilience and ability to adequately respond to a systemic and global crisis depend upon preexisting system-level characteristics and capacities at both the provincial and federal governance levels. By providing recommendations for policy and practice from a learning health system perspective, this paper contributes to the groundwork required for interdisciplinary research and genuine policy discussions to help health systems better prepare for future pandemics., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Alami, Lehoux, Fleet, Fortin, Liu, Attieh, Cadeddu, Abdoulaye Samri, Savoldelli and Ag Ahmed.)

Telehealth is seen as a key lever in health policy choices. However, many challenges remain in terms of its successful integration into clinical practices. To date, many telehealth initiatives are struggling to move beyond the pilot project stage. This is partly due to a culture of innovation that is mainly focused on the expected benefits of the technology and less on the changes and transformations it can generate. Telehealth is used in health care organizations with complex social dynamics, to say the least. Its introduction has unintended consequences that can affect patients, communities, professionals, organizations, health systems and society as a whole. The aim of this article is to discuss some of the unintended consequences of using telehealth in health care organizations and systems., (© 2020 Elsevier Masson SAS. All rights reserved.)

Introduction: Prior research has documented disparities in asthma outcomes between Latino children and non-Hispanic whites, but little research directly examines the care provided to Latino children over time in clinical settings., Methods: We utilized an electronic health record-based dataset to study basic asthma care utilization (timely diagnosis documentation and medication prescription) between Latino (Spanish preferring and English preferring) and Non-Hispanic white children over a 13-year study period., Results: In our study population (n = 37,614), Latino children were more likely to have Medicaid, be low income, and be obese than non-Hispanic white children. Latinos (Spanish preferring and English preferring) had lower odds than non-Hispanic whites of having their asthma recorded on their problem list on the first day the diagnosis was noted (odds ratio [OR] = 0.83; 95% CI, 0.77 to 0.89 Spanish preferring; OR = 0.93; 95% CI, 0.87 to 0.99 English preferring). Spanish-preferring Latinos had higher odds of ever receiving a prescription for albuterol (OR = 1.96; 95% CI, 1.52 to 2.52), inhaled corticosteroids (OR = 1.45; 95% CI, 1.01 to 2.09), or oral steroids (OR = 1.48; 95% CI, 1.07 to 2.04) than non-Hispanic whites. Among those with any prescription, Spanish-preferring Latinos had higher rates of albuterol prescriptions compared with non-Hispanic whites (adjusted rate ratio [aRR] = 1.0; 95% CI, 1.01 to 1.13)., Conclusions: In a multi-state network of clinics, Latino children were less likely to have their asthma entered on their problem list the first day it was noted than non-Hispanic white children, but otherwise did not receive inferior care to non-Hispanic white children in other measures. Further research can examine other parts of the asthma care continuum to better understand asthma disparities., Competing Interests: Conflicts of interest: None., (© Copyright 2020 by the American Board of Family Medicine.)

While the transition toward digitalized health care and service delivery challenges many publicly and privately funded health systems, patients are already producing a phenomenal amount of data on their health and lifestyle through their personal use of mobile technologies. To extract value from such user-generated data, a new insurance model is emerging called Pay-As-You-Live (PAYL). This model differs from other insurance models by offering to support clients in the management of their health in a more interactive yet directive manner. Despite significant promises for clients, there are critical issues that remain unaddressed, especially as PAYL models can significantly disrupt current collective insurance models and question the social contract in so-called universal and public health systems. In this paper, we discuss the following issues of concern: the quantification of health-related behavior, the burden of proof of compliance, client data privacy, and the potential threat to health insurance models based on risk mutualization. We explore how more responsible health insurance models in the digital health era could be developed, particularly by drawing from the Responsible Innovation in Health framework., (©Hassane Alami, Lysanne Rivard, Robson Rocha de Oliveira, Pascale Lehoux, Stéphanie Bernadette Mafalda Cadeddu, Mathilde Savoldelli, Mohamed Ali Ag Ahmed, Jean-Paul Fortin.

Artificial intelligence (AI) is seen as a strategic lever to improve access, quality, and efficiency of care and services and to build learning and value-based health systems. Many studies have examined the technical performance of AI within an experimental context. These studies provide limited insights into the issues that its use in a real-world context of care and services raises. To help decision makers address these issues in a systemic and holistic manner, this viewpoint paper relies on the health technology assessment core model to contrast the expectations of the health sector toward the use of AI with the risks that should be mitigated for its responsible deployment. The analysis adopts the perspective of payers (ie, health system organizations and agencies) because of their central role in regulating, financing, and reimbursing novel technologies. This paper suggests that AI-based systems should be seen as a health system transformation lever, rather than a discrete set of technological devices. Their use could bring significant changes and impacts at several levels: technological, clinical, human and cognitive (patient and clinician), professional and organizational, economic, legal, and ethical. The assessment of AI's value proposition should thus go beyond technical performance and cost logic by performing a holistic analysis of its value in a real-world context of care and services. To guide AI development, generate knowledge, and draw lessons that can be translated into action, the right political, regulatory, organizational, clinical, and technological conditions for innovation should be created as a first step., (©Hassane Alami, Pascale Lehoux, Yannick Auclair, Michèle de Guise, Marie-Pierre Gagnon, James Shaw, Denis Roy, Richard Fleet, Mohamed Ali Ag Ahmed, Jean-Paul Fortin.

It is very exceptional that a new disease becomes a true pandemic. Since its emergence in Wuhan, China, in late 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19, has spread to nearly all countries of the world in only a few months. However, in different countries, the COVID-19 epidemic takes variable shapes and forms in how it affects communities. Until now, the insights gained on COVID-19 have been largely dominated by the COVID-19 epidemics and the lockdowns in China, Europe and the USA. But this variety of global trajectories is little described, analysed or understood. In only a few months, an enormous amount of scientific evidence on SARS-CoV-2 and COVID-19 has been uncovered (knowns). But important knowledge gaps remain (unknowns). Learning from the variety of ways the COVID-19 epidemic is unfolding across the globe can potentially contribute to solving the COVID-19 puzzle. This paper tries to make sense of this variability-by exploring the important role that context plays in these different COVID-19 epidemics; by comparing COVID-19 epidemics with other respiratory diseases, including other coronaviruses that circulate continuously; and by highlighting the critical unknowns and uncertainties that remain. These unknowns and uncertainties require a deeper understanding of the variable trajectories of COVID-19. Unravelling them will be important for discerning potential future scenarios, such as the first wave in virgin territories still untouched by COVID-19 and for future waves elsewhere., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Introduction: Shortage of health workers is a worldwide problem but is particularly critical in sub-Saharan Africa. In Mali, the number of health workers is insufficient and their retention is low, particularly in rural and remote areas. Rural postings are unattractive to health workers. Very few studies have examined the factors contributing to the shortage and poor retention of health workers in Mali. The objective of this study is to identify and understand these factors with regards to skilled health workers in two rural health districts (Y&eacute;liman&eacute; and Bafoulab&eacute;) in the region of Kayes, Mali., Methods: This qualitative study is based on the conceptual framework of Lehman, Dieleman and Martineau. Data were collected through 46 in-depth interviews with health workers and decision-makers. A thematic content analysis was conducted with the support of QDA Miner software., Results: The study identified factors contributing to the insufficient allocation and poor retention of rural health workers in these districts. They are individual-level factors (gender, family situation, age), unattractive living and working conditions, community recognition and participation, quality of leadership, an unfavourable recruitment/assignment process and insufficient financial incentives. It shows that female staff have specific constraints that prevent them from deploying to or staying in rural areas for long periods. In addition, the number of staff recruited at the national level is unpredictable and insufficient, while their recruitment and assignment process is perceived to be inequitable and not very transparent, disadvantaging rural health structures. Some strategies were identified to improve the availability and retention of health workers in these areas. They take into account certain social norms, notably gender roles, and include the improvement of living and working conditions, as well as the strengthening of health workforce management., Conclusion: This study's findings highlight the multifaceted nature of factors contributing to the availability and retention of health workers in rural and remote areas of sub-Saharan Africa and the challenges associated with them. This study identifies some strategies that can be combined to facilitate the retention and availability of health workers in these areas. Some strategies involve actors outside the health sector, requiring joint efforts for their implementation. This research provides decision-makers with evidence to support informed decision making with regards to the retention of health workers in rural areas.

The World Health Organization and other institutions are considering Artificial Intelligence (AI) as a technology that can potentially address some health system gaps, especially the reduction of global health inequalities in low- and middle-income countries (LMICs). However, because most AI-based health applications are developed and implemented in high-income countries, their use in LMICs contexts is recent and there is a lack of robust local evaluations to guide decision-making in low-resource settings. After discussing the potential benefits as well as the risks and challenges raised by AI-based health care, we propose five building blocks to guide the development and implementation of more responsible, sustainable, and inclusive AI health care technologies in LMICs.

Aims: The effect of algae and its extract supplementation on glycolipid metabolism has not been finalized. Therefore, the purpose of the meta-analyses was to assess the effects of its supplementation on glycolipid metabolism concentration., Methods: We have systematically searched PubMed, Web of Science, the Cochrane Library and Embase to identify randomized controlled trials (RCTs) that investigated the impact of algae and its extracts supplementation on glycolipid metabolism. Effect size analysis was performed using weighted mean difference (WMD) and 95% CI between the methods of the experiment group and the control group. Subgroup analyses were performed to explore the possible influences of study characteristics. Publication bias and sensitivity analysis were also performed., Results: A total of 27 RCTs (31 trials) with 1221 participants were finally selected for the meta-analysis. The algae and its extract intervention significantly decreased glycosylated hemoglobin (HbA1c, WMD = -0.18%; 95% CI: -0.27 to -0.10; p < 0.001), high-density lipoprotein cholesterol (HDL-C, WMD = -0.22 mmol/L; 95% CI: -0.38 to -0.06; p = 0.008), and triglycerides (TC, WMD = -0.31 mmol/L; 95% CI: -0.37 to -0.25; p < 0.001) levels and increased insulin (WMD = 6.05 pmol/mL; 95% CI: 4.01 to 8.09; p < 0.001) levels. It did not significantly change the blood glucose, homeostasis model assessment-insulin resistance index (HOMA-IR), 2-h post-meal blood glucose (2hPBG) and other lipid profiles. Subgroup analyses based on the duration of intervention and subjects demonstrated that the intervention of algae and its extracts for 10 weeks or fewer and more than 40 subjects decreased TC levels ( p < 0.05). Moreover, the intervention reduced TC and 2hPBG concentrations for East Asians ( p < 0.05)., Conclusions: Our findings provided evidence that algae and its extract interventions were beneficial for the regulation of human glycolipid metabolism. More precise RCTs on subjects are recommended to further clarify the effect of algae, seaweed polysaccharide, seaweed polypeptide, algae polyphenol and its products intervention on glycolipid metabolism.

Digital technologies play a central role in strategies to improve access, quality and efficiency of health care and services. However, many digital health projects have failed to become sustainable and spread across health organizations and systems. This situation is partly due to the fact that these projects are often developed and evaluated by reducing the issues linked mainly to the technological dimension. Such tradition has paid little attention to the fact that technology is introduced into pluralistic and complex sociotechnical systems such as health organizations and systems. The aim of this article is to propose practical and theorical, non-prescriptive, elements of reflection that can serve as a basis for evaluating complex and innovative digital health projects. This reflection builds on the lessons learned from the application of a strategic framework for evaluating three major complex and innovative digital health projects in Quebec over the last 15 years.

Electronic health records (EHRs) are considered as a powerful lever for enabling value-based health systems. However, many challenges to their use persist and some of their unintended negative impacts are increasingly well documented, including the deterioration of work conditions and quality, and increased dissatisfaction of health care providers. The "quadruple aim" consists of improving population health as well as patient and provider experience while reducing costs. Based on this approach, improving the quality of work and well-being of health care providers could help rethinking the implementation of EHRs and also other information technology-based tools and systems, while creating more value for patients, organizations and health systems.

Aim: More than half of all maternal deaths worldwide occur in sub-Saharan Africa (SSA). For nomadic pastoralists (30 to 60 million) in SSA, the risk of maternal death is very high because of the low proportion of assisted deliveries in the areas where they live. The objective of this research was to understand the determinants of using skilled birth attendants in relation to the perceptions of quality, geographic accessibility, and financial affordability of health services by nomadic women., Methods: We used a qualitative research design, inspired by ethnography. Research was conducted in the commune of Gossi (Mali), where 90% of the population is nomadic. The study population consisted of 26 nomadic women living in their camps. Saturation and diversification guided sampling. Semi-structured individual interviews and non-participant observation enabled concomitant data collection. Thematic content analysis was performed using QDA Miner software., Results: Our results show that only 10 women used assisted childbirth for their last delivery. These women thought that health workers were competent and well trained, and they liked the fact that these workers were recruited locally. Similarly, these 10 women deemed the health workers' attitude acceptable and appreciated their availability. In contrast, the majority of participants (16 women) were prevented or discouraged from using skill birth attendants. Some of them did not use them because they were afraid of being undressed, of giving birth on a table, and especially of male staff. They also said that they did not have access to information about health services. In addition, respondents considered health services very difficult to access due to distances, unavailable means of transportation, and costs perceived as being expensive., Conclusion: Our results identify several determinants of the use or non-use of skilled birth attendants by nomadic women in relation to the context and way of life. In addition, our findings call for future research to better understand these determinants and to deepen, refine, and test emerging strategies that seem potentially hopeful with respect to facilitating the use of skilled birth attendance in SSA., (Copyright © 2019 Elsevier Ltd.

Proteasome 26S subunit non-ATPase 4 (PSMD4) is an important proteasome ubiquitin receptor and plays a key role in endoplasmic reticulum stress (ERS). However, the study of PSMD4 in esophageal cancer (EC) is relatively rare. Here, we found that the expression of PSMD4 was markedly enhanced in EC tissues and cell lines. The cell counting kit-8 (CCK-8) assay showed that overexpression of PSMD4 significantly enhanced Eca109 cell viability, while inhibition of PSMD4 reduced Eca109 cell viability. Knockdown of PSMD4 induced Eca109 cell apoptosis and cell cycle arrest. More importantly, knockdown of PSMD4 significantly enhanced the expression of glucose regulated protein 78, activating transcription factor 6, and p-protein kinase R-like ER kinase, indicating an enhanced ERS response in esophageal cancer cells. Compared with the control cells, brefeldin A significantly inhibited the expression of PSMD4 and increased the expression of p53-upregulated modulator of apoptosis. However, such effects were largely reversed after overexpressing PSMD4 in Eca109 cells, suggesting that silencing PSMD4 could enhance ERS-induced cell apoptosis. In summary, upregulation of PSMD4 promoted the progression of esophageal cancer mainly by reducing ERS-induced cell apoptosis., (© 2019 The Authors.

Background: In sub-Saharan Africa (SSA), nomads account for 30 to 60 million people. Their mobility, due to a constant search for pastures and water points, makes health services less accessible to them. Few nomadic women use assisted delivery, which increases the risk of maternal mortality. The reasons behind this limited use have been poorly documented. The objective of this study was to understand the sociocultural determinants of assisted childbirth by nomadic women., Methods: We conducted a qualitative research in the health area of Gossi (Mali), mainly populated by nomads. Data were collected through a literature review, 26 semi-structured interviews, a non-participant observation, and a logbook. Nomadic women who gave birth in the past three months were included in the study, whether they used assisted delivery or not. A thematic content analysis was performed with QDA Miner software., Results: The study identified a complex combination of determinants resulting in the use or non-use of assisted childbirth by the nomads of Gossi. Several participants recognized the value of assisted delivery but gave birth at home. They identified sociocultural determinants related to their representations and bodily experiences; the risks and emotions (fear, stress, anxiety) associated with pregnancy; the onset of labor and delivery; and their weak autonomy in terms of movement, decision-making, and economic agency. Nomadic women are not free in their movements, and in order to seek care, they require the permission and support of a man (husband, brother, or father). Furthermore, the participants are housewives, and men control family resources and make decisions regarding all financial matters. Assisted delivery is often only considered when there are complications., Conclusion: This research has made it possible to understand the sociocultural determinants of the use of assisted childbirth among nomadic women, which should be taken into account when organizing health services for these populations.

B vitamins are enzyme cofactors that play an important role in energy metabolism. The aim of this study was to elucidate whether B vitamin administration can reduce body weight (BW) gain by improving energy metabolism-related enzyme activities in rats fed on a highfat diet. Fifty rats were randomly assigned to one of the following five groups: control group (C), including rats fed on standard rat chow; four treatment groups (HO, HI, H2, and H3), in which rats were fed on a high-fat diet. Rats in the HI group were treated daily with 100 mg/kg BW thiamine (VB1), 100 mg/kg BW riboflavin (VB2), and 250 mg/kg BW niacin (VPP); rats in the H2 group were treated daily with 100 mg/kg BW pyridoxine (VB6), 100 mg/kg BW cobalamin (VB12), and 5 mg/kg BW folate (FA); and rats in the H3 group were treated daily with all of the B vitamins administered to the HI and H2 groups. After 12 weeks, the BW gains from the initial value were 154.5±58.4 g and 159.1±53.0 g in the HI and C groups, respectively, which were significantly less than the changes in the HO group (285.2±14.8 g, P<0.05). In the HO group, the plasma total cholesterol (CHO) and triglyceride (TG) levels were 1.59±0.30 mmol/L and 1,55±0.40 mmol/L, respectively, which were significantly greater than those in the HI group (1.19±0.18 mmol/L and 0.76±0.34 mmol/L, respectively, P<0.05). The activities of transketolase (TK), glutathione reductase, and Na + /K + adenosine triphosphatase were significantly increased in the B vitamin-treated groups and were significantly greater than those in the HO group (P<0.05). Furthermore, the glucose-6-phosphate dehydrogenase, pyruvic acid kinase, and succinate dehydrogenase activities also were increased after treatment with B vitamins. Supplementation with B vitamins could effectively reduce BW gain and plasma levels of lipids by improving energy metabolism-related enzyme activities in rats, thus possibly providing potential benefits to humans.

Objective: To investigate the genotypic diversity of Methicillin-resistant Staphylococcus aureus (MRSA) isolated from pigs and retail foods from different geographical areas in China and further to study the routes and rates of transmission of this pathogen from animals to food., Methods: Seventy-one MRSA isolates were obtained from pigs and retail foods and then characterized by multi-locus sequencing typing (MLST), spa typing, multiple-locus variable number of tandem repeat analysis (MLVA), pulsed-field gel electrophoresis (PFGE), and antimicrobial susceptibility testing., Results: All isolated MRSA exhibited multi-drug resistance (MDR). Greater diversity was found in food-associated MRSA (7 STs, 8 spa types, and 10 MLVA patterns) compared to pig-associated MRSA (3 STs, 1 spa type, and 6 MLVA patterns). PFGE patterns were more diverse for pig-associated MRSA than those of food-associated isolates (40 vs. 11 pulse types). Among the pig-associated isolates, CC9-ST9-t899-MC2236 was the most prevalent clone (96.4%), and CC9-ST9-t437-MC621 (20.0%) was the predominant clone among the food-associated isolates. The CC9-ST9 isolates showed significantly higher antimicrobial resistance than other clones. Interestingly, CC398-ST398-t034 clone was identified from both pig- and food-associated isolates. Of note, some community- and hospital-associated MRSA strains (t030, t172, t1244, and t4549) were also identified as food-associated isolates., Conclusion: CC9-ST9-t899-MC2236-MDR was the most predominant clone in pigs, but significant genetic diversity was observed in food-associated MRSA. Our results demonstrate the great need for improved surveillance of MRSA in livestock and food and effective prevention strategies to limit MDR-MRSA infections in China., (Copyright © 2017 The Editorial Board of Biomedical and Environmental Sciences.

Objective: To investigate the association between single-nucleotide polymorphisms (SNPs) in the Toll-like receptor 4 (TLR4) gene (TLR4) and the relationship between SNPs and type-2 diabetes mellitus (T2DM) complicated by tuberculosis (TB) (T2DMTB) susceptibility., Methods: The relationship between SNPs and T2DMTB was assessed using SNPstats (http://bioinfo.iconcologia.net/SNPstats). Generalised multifactor dimensionality reduction (GMDR) was used to select the best interaction combination of the four SNPs. Stratified analysis was performed using logistic regression., Results: Logistic analysis showed that both rs11536889 and rs7873784 in TLR4 were associated with risk of T2DMTB in additive and dominant models. Carriers with homozygous and heterozygous mutants of rs11536889 and rs7873784 were associated with higher T2DMTB risk than those with wild-type homozygotes (OR 1.68, 95%CI 1.22-2.17 and OR 1.61, 1.18-2.09, respectively). GMDR analysis indicated a significant two-locus model (P = 0.0107) involving rs7873784 and rs11536889; the cross-validation consistency of this model was 9/10, and testing accuracy was 60.11%. Participants with rs7873784-GC/CC and rs11536889-GC/CC genotypes had the highest risk of T2DMTB compared with participants with rs7873784-GG and rs11536889-GG genotypes (OR 3.32, 95%CI 2.12-4.63)., Conclusions: We found that> rs11536889 and rs7873784 in the TLR4 gene, and their interactions, were associated with increased T2DMTB risk.

Background: Circulating long-chain (LC) n-3 polyunsaturated fatty acid (PUFA) can provide objective measures that reflect both dietary consumption and relevant biological processes. Nevertheless, prospective cohort studies on circulating LC n-3 PUFA in relation to incidence of stroke have yielded inconsistent results. We therefore conducted a meta-analysis to quantitatively evaluate the association., Results: A total of 2,836 stroke events occurred among 20,460 individuals aged 35-79 yr from 10 prospective cohort studies. Circulating LC n-3 PUFA was significantly associated with reduced risk of stroke (RR: 0.86; 95% CI: 0.76, 0.98; I 2 = 0.00%), especially 22:5n-3 (RR: 0.74; 95% CI: 0.60, 0.92) and 22:6n-3 (RR: 0.78; 95% CI: 0.65, 0.94). The associations were more pronounced with ischemic stroke (RR: 0.81; 95% CI: 0.68, 0.96), but not with hemorrhagic stroke (RR: 0.95; 95% CI: 0.60, 1.49). A 1% increment of 22:5n-3 and 22:6n-3 proportions in circulating blood was associated with 25% (RR: 0.75; 95% CI: 0.64, 0.87) and 11% (RR: 0.89; 95% CI: 0.83, 0.95) reduced risk of stroke, respectively., Materials and Methods: Pertinent studies were identified from Cochrane Library, PubMed and EMBASE database through June 2017. Multivariate-adjusted risk ratios (RRs) with 95% confidence interval (CI) for incident stroke when comparing the top with the bottom tertiles of baseline LC n-3 PUFA proportions in blood were pooled using a random-effect model., Conclusions: Circulating LC n-3 PUFAs were linearly associated with reduced risk of stroke, especially 22:5n-3 and 22:6n-3. Such findings highlight the importance of circulating LC n-3 PUFA in the development of ischemic stroke., Competing Interests: CONFLICTS OF INTEREST The authors declare that they have no any conflicts of interests.

Aims: To investigate the association of several single nucleotide polymorphisms (SNPs) within Protein tyrosine phosphatase nonreceptor type 22 ( PTPN22 ) gene and additional gene- gene and gene- type 2 diabetes mellitus (T2DM) interaction with pulmonary tuberculosis (PTB) risk in Chinese Uygur population., Methods: A total of 722 participants (186 males, 536 females) were selected, including 360 PTB patients and 362 control participants. Generalized multifactor dimensionality reduction (GMDR) was used to screen the best interaction combination among SNPs and T2DM. Logistic regression was performed to investigate association between 3 SNPs within PTPN22 gene, additional gene- gene and gene- T2DM interaction on PTB risk., Results: Logistic regression analysis showed that PTB risk was significantly lower in carriers with rs2476601- CT genotype than those with CC genotype (CT versus CC), adjusted OR (95%CI) =0.42 (0.17-0.83), and higher in carriers with the rs33996649- GA genotype than those with GG genotype (GA versus GG), adjusted OR (95%CI) = 5.66 (2.24-9.47). We found a significant two-locus model (p=0.0010) involving rs33996649 and T2DM. Overall, the cross-validation consistency of this two- locus model was 10/ 10, and the testing accuracy was 60.11%. We also conducted stratified analysis for rs33996649 and T2DM using logistic regression. We found that T2DM patients with rs33996649 - GA genotype have the highest PTB risk, compared to non- T2DM patients with rs33996649- GG genotype, OR (95%CI) = 4.52 (2.71 -6.43), after covariates adjustment., Conclusions: We found that the T allele of rs2476601 and the A allele of rs33996649within PTPN22 gene, interaction between rs2476601 and T2DM were all associated with increased PTB risk., Competing Interests: CONFLICTS OF INTEREST None.

Access to health care is still limited for many women in sub-Saharan Africa (SSA), while it remains an important determinant of maternal mortality and morbidity. Information and communication technologies (ICTs), such as mhealth and telehealth, can help to facilitate this access by acting on the various obstacles encountered by women, be they socio-cultural, economic, geographical or organizational. However, various factors contribute to the success of mhealth and telehealth implementation and use, and must be considered for these technologies to go beyond the pilot project stage. The objective of this systematic literature review is to synthesize the empirical knowledge on the success factors of the implementation and use of telehealth and mhealth to facilitate access to maternal care in SSA. The methodology used is based on that of the Cochrane Collaboration, including a documentary search using standardized language in six databases, selection of studies corresponding to the inclusion criteria, data extraction, evaluation of study quality, and synthesis of the results. A total of 93 articles were identified, which allowed the inclusion of seven studies, six of which were on mhealth. Based on the framework proposed by Broens et al ., we synthesized success factors into five categories: (I) technology, such as technical support to maintain, troubleshoot and train users, good network coverage, existence of a source of energy and user friendliness; (II) user acceptance, which is facilitated by factors such as unrestricted use of the device, perceived usefulness to the worker, adequate literacy, or previous experience of use ; (III) short- and long-term funding; (IV) organizational factors, such as the existence of a well-organized health system and effective coordination of interventions; and (V) political or legislative aspects, in this case strong government support to deploy technology on a large scale. Telehealth and mhealth are promising solutions to reduce maternal morbidity and mortality in SSA, but knowledge on how these interventions can succeed and move to scale is limited. Success factors identified in this review can provide guidance on elements that should be considered in the design and implementation of telehealth and mhealth for maternal health in SSA., Competing Interests: Conflicts of Interest: The authors have no conflicts of interest to declare.

Background and Objectives: Peroral supplementation with trivalent-chromium (Cr) or magnesium (Mg) has been shown to improve insulin resistance (IR). The objective of this study was to determine whether combined peroral supplementation with Cr and Mg improves IR more effectively than Cr or Mg alone., Methods and Study Design: Subjects (n=120, age range 45-59 years old) and diagnosed with IR were randomly divided into four groups and monitored for a period of 3 months: group 1 (the placebo control group), group 2 (160 μg/d Cr), group 3 (200 mg/d Mg), and group 4 (160 μg/d Cr plus 200 mg/d Mg). Fasting blood glucose (FBG), fasting insulin (FIns), erythrocyte Cr and Mg content, and glucose-transporter-4 (GLUT4) and glycogen-synthase-kinase-3β (GSK3β) mRNA levels in activated T-lymphocytes were measured, and insulin resistant index (IRI) was calculated., Results: Significant decreases between the baseline and study conclusion values of FBG (0.37 mmol/L, p<0.01), FIns (2.91 μIU/mL, p<0.01) and IRI (0.60, p<0.01) were observed in group 4, but not groups 1-3. Similarly, compared with baseline, significant changes in GLUT4 (2.9-fold increase, p<0.05) and GSK3β (2.2-fold decrease, p<0.05) mRNA levels in activated T-lymphocyte were observed at the study's conclusion in group 4, but not in groups 1-3., Conclusions: Our results indicate that combining peroral supplementation with Cr and Mg improves IR more effectively than Cr or Mg alone, and this may be attributable to increased induction and repression, respectively, of GLUT4 and GSK3β expression.

Au Mali, les nomades (des Maures, Touaregs et Peulhs) représentent environ 1,25 million de personnes. Les services de santé leur sont peu accessibles en raison de leur mobilité, liée à leur activité d'élevage. La question que se posent plusieurs intervenants en santé publique des pays où vivent ces nomades est de savoir comment améliorer leur santé. Dans ce commentaire, après un bref exposé des problèmes liés à l'accès aux services de santé, nous proposons une approche innovante et holistique de la santé, qui soutient que des agents de santé communautaires (ASC) pourraient contribuer à améliorer la santé des nomades en offrant conjointement des services de santé aux nomades et à leurs animaux (le concept « One Health » [d'Une Seule Santé]). Des pistes de réflexion sont dégagées, quant aux principaux défis pour leur efficacité et durabilité, qui sont la conception et gestion du programme, leur soutien par les communautés et leur intégration aux services de santé publique et vétérinaire., (© The Author(s) 2015.)

This study aimed to develop a Chinese Mental Resilience Scale. A total of 2500 healthy participants, in two representative samples of the Chinese population, were administered the scale. Exploratory factor analysis, confirmatory factor analysis, and correlation analysis were used to obtain the relevant coefficients and verify the reliability and validity of the scale. Five factors were extracted: willpower, family support, optimism and self-confidence, problem solving, and interpersonal interaction, plus a lying subscale, which together accounted for 54 percent of the total variance. The Chinese Mental Resilience Scale demonstrated good psychometric properties. It can be used to evaluate the mental resilience level of general Chinese population., (© The Author(s) 2014.)

The authors report a case of soft palate perforation during endemic syphilis. The diagnosis of endemic syphilis was based on the absence of factor in favor of venereal syphilis, highly positive results suggesting VDRL/TPHA association, histology of velar perforation banks and the satisfactory response with closure of the perforation velar after 4 weeks of treatment with Benzathine benzylpenicillin., (Le comitée de rédaction se réserve le droit de revoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.

Background: The prevalence of drug-resistant tuberculosis (TB) in Xinjiang is higher than in other regions of China, and Beijing/W lineage Mycobacterium tuberculosis (MTB) is the dominant strain of MTB in Xinjiang. However, information on multidrug-resistant (MDR) and extensively drug-resistant (XDR) TB, particularly the correlation between MDR and the Beijing/W lineage and the correlation between drug resistance and the Beijing/W sublineage strains, is limited., Material/methods: We conducted a prospective study to describe the prevalence of MDR/XDR TB, Beijing/W lineage and sublineage strains in Xinjiang in China from 2009 to 2013. All MTB underwent drug susceptibility testing to the first- and second-line anti-tuberculosis drugs. The Beijing/W lineages and sublineages were detected by large-sequence polymorphisms with polymerase chain reaction., Results: A total of 410 clinical isolates were identified. The overall percentage of MDR and XDR cases in Xinjiang was 13.2% (54/410) and 13.0% (7/54), respectively. Overall, 9.8% (14/143) of the Beijing lineage MTB were MDR patients, and 15.6% (40/257) of the Non-Beijing lineage MTB were MDR patients. In the 143 Beijing MTB lineages, 11.2% isolates were in sublineage 105, 15.4% isolates were in sublineage 207, 69.2% isolates were in sublineage 181, and 4.2% isolates were in sublineage 150. None of the isolates were detected in sublineage 142. Significant differences between the Beijing/W and non-Beijing/W strains were observed regarding INH and EMB resistance, respectively., Conclusions: The prevalence of the MDR TB in Xinjiang remains high and imposes challenges for TB control. Four Beijing/W sublineage isolates were observed in Xinjiang. There was no correlation between MDR and the Beijing/W lineage and no correlation between drug resistance and the Beijing/W sublineage strains. Surveillance of the clinical isolates of MTB is recommended to strengthen the identification of MDR/XDR TB and sublineages of the Beijing/W strains.

Objective: The tuberculosis (TB) program was carried out in the Changji zone in northwest of China. Directly Observed Treatment, Short-Course (DOTS) is a modern control strategy against tuberculosis recommended by World Health Organization. The purpose of this work is to describe the survival of post-treatment TB (PTB) patients and to identify the risk factors associated with mortality and treatment outcomes, so that effective measures and interventions could be used to decrease the mortality rate., Patients and Methods: Registry of 4501 TB patients at Center for Disease Control and Prevention (CDC) treated from 2007 to 2014 were collected. Mortality was used as an outcome measure and calculated per 100 person years of observation (PYO) from the date of completion of the treatment to the date of interview if the patients were alive or to the date of death. Kaplan-Meier and Cox regression methods were used to determine the survival and hazard ratios. An indirect method of standardization was used to calculate the standard mortality ratio (SMR)., Results: The average PYO was 5.0 and the total was 21851. Mortality per 100 PYO was 1.9/100 PYO [223/11871] for smear-positive, 3.4/100 PYO [305/9048] for smear-negative and 2.4/100 PYO [22/932] for EPTB cases. Univariate and Cox regression analysis showed that age (p < 0.01), education (p < 0.01), occupation (p < 0.01) and economic status (p < 0.01) were associated with increased mortality., Discussion: Since the mortality rate was higher in Post-treatment TB patients than the general population these patients need special health care. An integrated survival and associated mortality risk factors and information system is necessary for TB surveillance, personal health status and treatment management. Further studies are required to identify the causes of death in these patients.

Objective: To investigate whether there is an association between diameter of bacille Calmette-Guérin (BCG) scars and effect of purified protein derivative (PPD) reaction and to determine whether vitamin A (VA) combined vitamin D (VD) supplementation influences the immune response to BCG revaccinated in Chinese infants., Methods: A cross-section and 3-month community-randomised trial was conducted. A total of 5 629 infants at 3, 6 and 12 months of age in Junan County of China were examined for BCG scar formation. Then, 597 revaccinated infants were randomly assigned to supplementation (n=307) and control (n=290) groups. The supplementation group were daily assigned to 1 500 IU VA and 500 IU VD for 3 months. Then all infants were subjected to skin test with PPD., Results: The diameter of BCG scars was positively correlated with diameter of skin indurations of PPD (r=0.17, P<0.05) in the 5 629 infants. The rate of positive response to PPD was higher in the supplementation group than in the control group (96.1% versus 89.7%, P<0.05, prevalence ratio 1.07, 95% CI 1.02-1.12). The prevalence ratio of PPD response for the supplementation group compared with that for the control group was 1.07 (95% CI 1.01-1.13) for the males and 1.08 (95% CI 1.00-1.17) for the females. For the supplementation group, the males got larger tuberculin induration than the females [(0.73±0.21) cm versus (0.67±0.20) cm, P<0.05) after intervention., Conclusions: The diameter of BCG scars was effectively correlated with PPD response, which indicates BCG scar formation may be an useful tool to evaluate the effect of tuberculosis prevention. VA combined VD supplementation may play an immuno-regulatory role in BCG revaccination. This may contribute to the prevention of childhood tuberculosis., (Copyright © 2014 Hainan Medical College.
