RESUMO
An estimated 350 million cases of STIs occur globally each year. In Sweden, Chlamydia is the most common STI with approximately 30 000 cases annually, disproportionally affecting youth. National surveys report low condom use among youth. Smartphone coverage is high among this tech-savvy group. In collaboration with youth, we developed an interactive smartphone application comprising games, peer experiences and information snippets to promote condom use. OBJECTIVES: To evaluate in a randomised controlled trial, the effectiveness of this smartphone application to improve condom use among youth in Stockholm, Sweden. METHODS: This two-arm, individually randomised controlled trial was implemented through the Youth Health Clinics (YHC) in Stockholm, Sweden. Youth aged 18-23 years, who owned a smartphone and had ≥2 sexual partners during the past 6 months were eligible. The intervention delivered the interactive elements described above over 180 days. The control group received a 'dummy' application. Both groups received standard of care at the YHC. The primary outcome was proportion of consistent (100%) self-reported condom use at 6 months. Secondary outcomes included self-reported number of partners, occurrence of STIs/pregnancy and STI tests during the study period. An intention-to-treat approach was used. RESULTS: 214 and 219 youth were randomised to the intervention and control groups, respectively. Consistent condom use was reported for 32/214 (15.0%) in the intervention group and for 35/219 (16.0%) in the control group (OR 0.9, 95% CI 0.5 to 1.6). No significant differences in secondary outcomes were seen. CONCLUSION: We were unable to detect an effect of the intervention. Future research should focus on targeting different subgroups within the overall risk group, with tailored mHealth interventions. The potential for such interventions in settings where sexual health services are unavailable should be evaluated. TRIAL REGISTRATION NUMBER: ISRCTN13212899.

Male circumcision is considered by some to be an acceptable global approach to reduce HIV infections. Consequently, many governments in sub-Saharan Africa run voluntary male circumcision programmes. South Africa also provides male circumcision for free at state clinics and hospitals. Very little is known about the men who use this service. This study uses data from Cape Town, a sample of 1194 in 2016, and from Mangaung, a sample of 277 in 2017 and 2018, to fill this gap. The study finds that age targeting is inadequate, risk targeting is absent, and religious and cultural factors have a negative effect on the cost-efficiency of the service in the long run.

BACKGROUND: Falls are one of the most common safety concerns in long-term care facilities (LTCFs). OBJECTIVE: To evaluate the associations between the environmental hazards and the fall risk in LTCF residents. DESIGN: Prospective study with 12-month follow-up. SETTING: Twenty-five LTCFs in a central district of Shanghai. SUBJECTS: A total of 739 older people participated and 605 were followed up for 1 year. METHODS: Environmental hazards were measured using a 75-item Environment Assessment Checklist, and the associations between environmental hazards and falls were analysed using univariate and multilevel logistic regressions. RESULTS: The incidence of falls was 0.291 per person with 11 items/LTCF of hazards on average. The most common hazard items were inadequate/inappropriate handrails (96% LTCFs; odds ratio (OR) for falls: 1.88 [95% confidence interval: 1.13-3.13]), unsafe floors (92% LTCFs; 2.50 [1.11-5.61]) and poor lighting (84% LTCFs; 2.01 [1.10-3.66]). Environmental hazards were most frequently distributed in bedrooms (96% LTCFs), shared toilets/showers (80% LTCFs) and individual toilets/showers (68%LTCFs) and accounted for 20% of the differences in falls occurrence among the LTCFs. After adjusting for individual intrinsic and fall-related behavioural factors, it is found that having more than eight environmental hazard items increased the fall risk among older residents (adjusted OR = 4.01 [1.37-11.73]). Environmental hazards and toilet visits at night showed significant associations with falls (adjusted OR = 5.97 [1.10-32.29]). CONCLUSIONS: The high prevalence of environmental hazards associated with falls highlights the urgency of improving environmental safety in LTCFs and the need of environmental safety policies, resource allocation and interventions in falls prevention.

INTRODUCTION: Falls are currently the top safety problem in long-term care facilities (LTCFs) in China. Due to the increasing number of residents living in LTCFs, more evidence is needed to give a foundation for fall prevention. OBJECTIVE: This study aimed to explore the epidemiological characteristics of falls in LTCFs in central Shanghai. METHODS: The study was conducted in 21 LTCFs in a central district in Shanghai, with a capacity of 3,065 residents. A two-stage sampling method was applied in participant recruitment. Falls were recorded by LTCF staff over a 12-month period. Details of falls were obtained by face-to-face interviews. The χ2 test was used in data analyses. RESULTS: The incidence of falls was 13.5%; 64.0% falls resulted in injuries, with 32.0% involving fractures. Women had a significantly higher incidence of injurious falls than men (χ2 = 4.066, p = 0.044). Residents aged 80-89 years or in level 1 care had the highest incidence of falls with severe consequences. The incidence of falls was significantly higher at small- or medium-sized LTCFs, public LTCFs, and LTCFs with higher environmental risk levels compared to their counterparts. Most falls occurred when walking on a flat floor (28.9%) and rising up or sitting down (24.0%); 40.9% occurred during the night. Of those injured, 54.8% were treated in hospitals, and only 53.7% completely recovered. CONCLUSIONS: Though the average incidence of falls in LTCFs in Shanghai was relatively low, great variation was observed between LTCFs, and severe consequences occurred frequently. Fall prevention programmes should be evidence-based with applicable devices and individualized care services and supports. The roles of personal and institutional factors on falls warrant further study.

BACKGROUND: Genital Chlamydia trachomatis infection is a major public health problem worldwide affecting mostly youth. Sweden introduced an opportunistic screening approach in 1982 accompanied by treatment, partner notification and case reporting. After an initial decline in infection rate till the mid-90s, the number of reported cases has increased over the last two decades and has now stabilized at a high level of 37,000 reported cases in Sweden per year (85% of cases in youth). Sexual risk-taking among youth is also reported to have significantly increased over the last 20 years. Mobile health (mHealth) interventions could be particularly suitable for youth and sexual health promotion as the intervention is delivered in a familiar and discrete way to a tech savvy at-risk population. This paper presents a protocol for a randomized trial to study the effect of an interactive mHealth application (app) on condom use among the youth of Stockholm. METHODS: 446 youth resident in Stockholm, will be recruited in this two arm parallel group individually randomized trial. Recruitment will be from Youth Health Clinics or via the trial website. Participants will be randomized to receive either the intervention (which comprises an interactive app on safe sexual health that will be installed on their smart phones) or a control group (standard of care). Youth will be followed up for 6 months, with questionnaire responses submitted periodically via the app. Self-reported condom use over 6 months will be the primary outcome. Secondary outcomes will include presence of an infection, Chlamydia tests during the study period and proxy markers of safe sex. Analysis is by intention to treat. DISCUSSION: This trial exploits the high mobile phone usage among youth to provide a phone app intervention in the area of sexual health. If successful, the results will have implications for health service delivery and health promotion among the youth. From a methodological perspective, this trial is expected to provide information on the strength and challenges of implementing a partially app (internet) based trial in this context. TRIAL REGISTRATION: ISRCTN 13212899, date of registration June 22, 2017.

BACKGROUND: Tuberculosis (TB) patients with multiple episodes of anti-TB treatment represent an important source of TB transmission, as well as a serious threat to the control of drug resistant TB, due to the high risk of multidrug and extensively drug resistance (MDR/XDR) and elongating infectiousness of this patient group. In this study we analyzed the possible risk of development and transmission of MDR and XDR in TB patients with multiple episodes of previous treatment history. METHODS: The study subjects were pulmonary TB patients who had at least two episodes of previous anti-TB treatment. A total of 166 eligible patients were identified from 10 counties/districts distributed in east, west, north, south and central China. Drug susceptibility test (DST) was performed by proportion method on LJ-media for the 1st line anti-TB drugs and a line probe assay was used to detect mutations related to resistance of the key 2nd-line drugs. Genotyping of M. tuberculosis (Mtb) was performed with MIRU-VNTR and Spoligotyping. RESULTS: Resistances to 1st-line drugs was observed in 122 (73.5%) of the 166 Mtb isolates with 97 (58.4%) being MDR-TB. Mutations relevant to 2nd-line drug resistance was seen in 63 isolates, including 35 MDR-TB isolates (30 pre-XDR, 5 XDR-TB). The Spoligotyping revealed 83.1% Mtb isolates belonged to the Beijing family. The MIRU-VNTR based genotyping revealed 32 (19.3%) of patients were infected with more than one strain. The number of previous TB treatment episode was found being significantly associated with the risk of MDR-TB and XDR-TB. Among the remaining 134 patients infected with a single Mtb strain, MIRU-VNTR revealed a high homogeneity of strain especially within Beijing family despite the polymorphic variations along with geographic locations. CONCLUSIONS: The high genetic relatedness and risk of MDR-TB and subsequent pre-XDR and XDR-TB among repeatedly treated patients suggest the establishment of M/XDR Mtb in this specific patient population. It highlights the urgent needs of providing DST of both 1st- and 2nd-line drugs before and during the medication in China's MDR-TB control program. Furthermore, the possibility of infection with multiple strains should also be considered to be associated with the drug resistance, which calls for the modification of treatment regimen.

BACKGROUND: The effect of peer support on virologic and immunologic treatment outcomes among HIVinfected patients receiving antiretroviral therapy (ART) was assessed in a cluster randomized controlled trial in Vietnam. METHODS: Seventy-one clusters (communes) were randomized in intervention or control, and a total of 640 patients initiating ART were enrolled. The intervention group received peer support with weekly home-visits. Both groups received first-line ART regimens according to the National Treatment Guidelines. Viral load (VL) (ExaVir™ Load) and CD4 counts were analyzed every 6 months. The primary endpoint was virologic failure (VL >1000 copies/ml). Patients were followed up for 24 months. Intention-to-treat analysis was used. Cluster longitudinal and survival analyses were used to study time to virologic failure and CD4 trends. RESULTS: Of 640 patients, 71% were males, mean age 32 years, 83% started with stavudine/lamivudine/nevirapine regimen. After a mean of 20.8 months, 78% completed the study, and the median CD4 increase was 286 cells/µl. Cumulative virologic failure risk was 7.2%. There was no significant difference between intervention and control groups in risk for and time to virologic failure and in CD4 trends. Risk factors for virologic failure were ART-non-naïve status [aHR 6.9;(95% CI 3.2-14.6); p < 0.01]; baseline VL ≥100,000 copies/ml [aHR 2.3;(95% CI 1.2-4.3); p < 0.05] and incomplete adherence (self-reported missing more than one dose during 24 months) [aHR 3.1;(95% CI 1.1-8.9); p < 0.05]. Risk factors associated with slower increase of CD4 counts were: baseline VL ≥100,000 copies/ml [adj.sq.Coeff (95% CI): -0.9 (-1.5;-0.3); p < 0.01] and baseline CD4 count <100 cells/µl [adj.sq.Coeff (95% CI): -5.7 (-6.3;-5.4); p < 0.01]. Having an HIV-infected family member was also significantly associated with gain in CD4 counts [adj.sq.Coeff (95% CI): 1.3 (0.8;1.9); p < 0.01]. CONCLUSION: There was a low virologic failure risk during the first 2 years of ART follow-up in a rural low-income setting in Vietnam. Peer support did not show any impact on virologic and immunologic outcomes after 2 years of follow up. TRIAL REGISTRATION: NCT01433601 .

BACKGROUND: In many countries in Asia, the HIV epidemic is in a concentrated phase, with high prevalence in certain risk groups, such as men who inject drugs. There is also a rapid increase of HIV among women. The latter might be due to high levels of sero-discordant couples and increasing transmission from male to female partners over time. METHODS: All adult married patients initiating antiretroviral treatment at four out-patient clinics in Quang Ninh province in north-eastern Vietnam between 2007 and 2009 were asked to participate in the study. Clinical information was extracted from patients' records, and a structured questionnaire was used to collect social, demographic and economic data. RESULTS: Two hundred eighty-eight married patients for whom information on the HIV status of their spouse was available were included in the study. Overall, the sero-discordance rate was 58%. The sero-discordance rate was significantly higher among married males, 71% had spouses not infected, than married females, of whom 18% had spouses not infected. Other factors associated with a high rate of sero-discordance were injection drug use (IDU) history, tuberculosis (TB) history and the availability of voluntary counselling and testing (VCT) in residential locations. High sero-concordance was associated with college/university education. CONCLUSION: The sero-discordance was significantly higher among married males than married females. Other factors also related to high sero-discordance were history of IDU, history of TB and the availability of VCT in residential locations. In contrast, college/university education and female sex were significantly related to low sero-discordance. To contain the increasing HIV prevalence among women, measures should be taken to prevent transmission among sero-discordant couples. Trial registration NCT01433601.

BACKGROUND: Syndromic surveillance systems (SSSs) collect non-specific syndromes in early stages of disease outbreaks. This makes an SSS a promising tool for the early detection of epidemics. An Integrated Surveillance System in rural China (ISSC project), which added an SSS to the existing Chinese surveillance system for the early warning of epidemics, was implemented from April 2012 to March 2014 in Jiangxi and Hubei Provinces. This study aims to measure the costs and effectiveness of the three components of the SSS in the ISSC project. METHODS: The central measures of the cost-effectiveness analysis of the three components of the syndromic surveillance system were: 1) the costs per reported event, respectively, at the health facilities, the primary schools and the pharmacies; and 2) the operating costs per surveillance unit per year, respectively, at the health facilities, the primary schools and the pharmacies. Effectiveness was expressed by reporting outputs which were numbers of reported events, numbers of raw signals, and numbers of verified signals. The reported events were tracked through an internal data base. Signal verification forms and epidemiological investigation reports were collected from local country centers for disease control and prevention. We adopted project managers' perspective for the cost analysis. Total costs included set-up costs (system development and training) and operating costs (data collection, quality control and signal verification). We used self-designed questionnaires to collect cost data and received, respectively, 369 and 477 facility and staff questionnaires through a cross-sectional survey with a purposive sampling following the ISSC project. All data were entered into Epidata 3.02 and exported to Stata for descriptive analysis. RESULTS: The number of daily reported events per unit was the highest at pharmacies, followed by health facilities and finally primary schools. Variances existed within the three groups and also between Jiangxi and Hubei. During a 15-month surveillance period, the number of raw signals for early warning in Jiangxi province (n = 36) was nine times of that in Hubei. Health facilities and primary schools had equal numbers of raw signals (n = 19), which was 9.5 times of that from pharmacies. Five signals were confirmed as outbreaks, of which two were influenza, two were chicken pox and one was mumps. The cost per reported event was the highest at primary schools, followed by health facilities and then pharmacies. The annual operating cost per surveillance unit was the highest at pharmacies, followed by health facilities and finally primary schools. Both the cost per reported event and the annual operating cost per surveillance unit in Jiangxi in each of the three groups were higher than their counterparts in Hubei. CONCLUSIONS: Health facilities and primary schools are better sources of syndromic surveillance data in the early warning of outbreaks. The annual operating costs of all the three components of the syndromic surveillance system in the ISSC Project were low compared to general government expenditures on health and average individual income in rural China.

BACKGROUND: Studies into the costs of syndromic surveillance systems are rare, especially for estimating the direct costs involved in implementing and maintaining these systems. An Integrated Surveillance System in rural China (ISSC project), with the aim of providing an early warning system for outbreaks, was implemented; village clinics were the main surveillance units. Village doctors expressed their willingness to join in the surveillance if a proper subsidy was provided. This study aims to measure the costs of data collection by village clinics to provide a reference regarding the subsidy level required for village clinics to participate in data collection. METHODS: We conducted a cross-sectional survey with a village clinic questionnaire and a staff questionnaire using a purposive sampling strategy. We tracked reported events using the ISSC internal database. Cost data included staff time, and the annual depreciation and opportunity costs of computers. We measured the village doctors' time costs for data collection by multiplying the number of full time employment equivalents devoted to the surveillance by the village doctors' annual salaries and benefits, which equaled their net incomes. We estimated the depreciation and opportunity costs of computers by calculating the equivalent annual computer cost and then allocating this to the surveillance based on the percentage usage. RESULTS: The estimated total annual cost of collecting data was 1,423 Chinese Renminbi (RMB) in 2012 (P25 = 857, P75 = 3284), including 1,250 RMB (P25 = 656, P75 = 3000) staff time costs and 134 RMB (P25 = 101, P75 = 335) depreciation and opportunity costs of computers. CONCLUSIONS: The total costs of collecting data from the village clinics for the syndromic surveillance system was calculated to be low compared with the individual net income in County A.

BACKGROUND: Infections caused by soil-transmitted helminths (STHs) are the most prevalent neglected tropical diseases and result in a major disease burden in low- and middle-income countries, especially in school-aged children. Improved diagnostic methods, especially for light intensity infections, are needed for efficient, control and elimination of STHs as a public health problem, as well as STH management. Image-based artificial intelligence (AI) has shown promise for STH detection in digitized stool samples. However, the diagnostic accuracy of AI-based analysis of entire microscope slides, so called whole-slide images (WSI), has previously not been evaluated on a sample-level in primary healthcare settings in STH endemic countries. METHODOLOGY/PRINCIPAL FINDINGS: Stool samples (n = 1,335) were collected during 2020 from children attending primary schools in Kwale County, Kenya, prepared according to the Kato-Katz method at a local primary healthcare laboratory and digitized with a portable whole-slide microscopy scanner and uploaded via mobile networks to a cloud environment. The digital samples of adequate quality (n = 1,180) were split into a training (n = 388) and test set (n = 792) and a deep-learning system (DLS) developed for detection of STHs. The DLS findings were compared with expert manual microscopy and additional visual assessment of the digital samples in slides with discordant results between the methods. Manual microscopy detected 15 (1.9%) Ascaris lumbricoides, 172 (21.7%) Tricuris trichiura and 140 (17.7%) hookworm (Ancylostoma duodenale or Necator americanus) infections in the test set. Importantly, more than 90% of all STH positive cases represented light intensity infections. With manual microscopy as the reference standard, the sensitivity of the DLS as the index test for detection of A. lumbricoides, T. trichiura and hookworm was 80%, 92% and 76%, respectively. The corresponding specificity was 98%, 90% and 95%. Notably, in 79 samples (10%) classified as negative by manual microscopy for a specific species, STH eggs were detected by the DLS and confirmed correct by visual inspection of the digital samples. CONCLUSIONS/SIGNIFICANCE: Analysis of digitally scanned stool samples with the DLS provided high diagnostic accuracy for detection of STHs. Importantly, a substantial number of light intensity infections were missed by manual microscopy but detected by the DLS. Thus, analysis of WSIs with image-based AI may provide a future tool for improved detection of STHs in a primary healthcare setting, which in turn could facilitate monitoring and evaluation of control programs.

PROBLEM: The Chinese central government launched the Health System Reform Plan in 2009 to strengthen disease control and health promotion and provide a package of basic public health services. Village doctors receive a modest subsidy for providing public health services associated with the package. Their beliefs about this subsidy and providing public health services could influence the quality and effectiveness of preventive health services and disease surveillance. APPROACH: To understand village doctors' perspectives on the subsidy and their experiences of delivering public health services, we performed 10 focus group discussions with village doctors, 12 in-depth interviews with directors of township health centres and 4 in-depth interviews with directors of county-level Centers for Disease Control and Prevention. LOCAL SETTING: The study was conducted in four counties in central China, two in Hubei province and two in Jiangxi province. RELEVANT CHANGES: Village doctors prioritize medical services but they do their best to manage their time to include public health services. The willingness of township health centre directors and village doctors to provide public health services has improved since the introduction of the package and a minimum subsidy, but village doctors do not find the subsidy to be sufficient remuneration for their efforts. LESSONS LEARNT: Improving the delivery of public health services by village doctors is likely to require an increase in the subsidy, improvement in the supervisory relationship between village clinics and township health centres and the creation of a government pension for village doctors.
Résumé PROBLÈME: Le gouvernement central chinois a lancé le plan de réforme du système de santé en 2009 pour renforcer la lutte contre les maladies et l'amélioration de la santé, et pour fournir un paquet de services de base en termes de santé publique. Les médecins de village reçoivent une subvention modeste pour offrir des services de santé publique liés à ce paquet. Leurs opinions sur cette subvention et la fourniture de services de santé publique pourraient avoir une influence sur la qualité et l'efficacité des services de santé préventive et sur la surveillance des maladies. APPROCHE: Pour comprendre les perspectives des médecins de village sur la subvention et leur expérience dans le domaine de la fourniture de services de santé publique, nous avons organisé 10 discussions de groupe cible avec des médecins de village, 12 entrevues approfondies avec des directeurs de centres de santé cantonaux et 4 entrevues approfondies avec des directeurs départementaux de centres pour la lutte et la prévention des maladies. ENVIRONNEMENT LOCAL: L'étude a été effectuée dans quatre comtés du centre de la Chine, deux dans la province de Hubei et deux dans la province du Jiangxi. CHANGEMENTS SIGNIFICATIFS: Les médecins de village donnent la priorité aux services médicaux, mais ils font de leur mieux pour gérer leur temps de manière à inclure les services de santé publique. La volonté des directeurs de centres de santé cantonaux et des médecins de village d'offrir des services de santé publique s'est accrue depuis l'introduction du paquet et d'une subvention minimale, mais les médecins de village ne considèrent pas que cette subvention constitue une rémunération suffisante pour leurs efforts. LEÇONS TIRÉES: Il est possible que l'amélioration de la fourniture de services de santé publique par les médecins de village nécessite une augmentation de la subvention, l'amélioration de la relation de supervision entre cliniques de village et centres de santé cantonaux et la création d'une pension gouvernementale pour les médecins de village.
Resumen SITUACIÓN: En el año 2009, el gobierno central chino puso en marcha el plan de reforma del sistema sanitario con el objetivo de reforzar el control de las enfermedades y fomentar la salud, así como proporcionar un paquete de servicios básicos de salud pública. Los médicos rurales perciben una modesta subvención por la prestación de los servicios de salud pública relacionados con dicho paquete. Sus opiniones acerca de dicha subvención y la prestación de los servicios de salud pública podrían influir en la calidad y la eficacia de los servicios sanitarios preventivos y de la vigilancia de las enfermedades. ENFOQUE: Con objeto de comprender los puntos de vista de los médicos rurales acerca de la subvención y sus experiencias en la prestación de servicios sanitarios, hemos llevado a cabo 10 debates con grupos focales de médicos rurales, 12 entrevistas en detalle con directores de centros de salud municipales y 4 entrevistas en detalle con directores de Centros para el Control y Prevención de las Enfermedades provinciales. MARCO REGIONAL: El estudio se llevó a cabo en cuatro condados del centro de China, dos de ellos en la provincia de Hubei y otros dos en la de Jiangxi. CAMBIOS IMPORTANTES: Los médicos rurales dan prioridad a los servicios médicos, pero hacen todo lo posible por gestionar su tiempo a fin de incluir los servicios de salud pública. La disposición de los directores de los centros sanitarios municipales y de los médicos rurales para prestar los servicios de salud pública ha aumentado desde la introducción del paquete y de la subvención mínima, si bien los médicos rurales no consideran que sea una retribución suficiente por sus esfuerzos. LECCIONES APRENDIDAS: Es probable que, para mejorar la prestación de servicios de salud pública por parte de los médicos rurales, sea necesario un aumento de la subvención, una mejora en la relación de supervisión entre las clínicas rurales y los centros de salud municipales, así como la creación de una pensión gubernamental para los médicos rurales.

Purpose: To compare the effects on verbal fluency of a supported yoga-based exercise intervention to an aerobic exercise intervention and a wait-list control group. Participants and Methods: Eighty-two physically-inactive but otherwise healthy adults (mean age 72.5 years, range 65-85, 77% female) were recruited into a 12-week, three-group, parallel randomized controlled trial. Participants were supported to complete ≥3 Hatha yoga classes per/week or ≥3 structured aerobic exercise sessions/week. A wait-list control group continued usual daily activities only. Verbal fluency, including total-FAS, animals, and verbs, was assessed before and after interventions. Group effects were assessed using analysis of covariance (ANCOVA). Results: Twenty-seven participants were randomized to yoga, 29 to aerobic exercise and 26 to a waitlist. At 12-week follow-up, compared to baseline, there were increases in mean total-FAS in the yoga (+5.0 words, p=0.002) and aerobic exercise groups (+6.6 words, p=0.004). Mean total-FAS in the wait-list control group remained stable (-0.5 words, p=0.838). There were medium-magnitude estimated treatment effects on total-FAS for yoga versus wait-list control and aerobic exercise versus wait-list control: Hedges' g=0.51 (p=0.213) and 0.57 (p=0.098) respectively. In addition, small-to-medium magnitude estimated treatment effects were seen on animals and verbs for yoga versus wait-list control and aerobic exercise versus wait-list control: g=0.28 (p=0.155), 0.19 (p=0.766) and 0.50 (p=0.085), 0.59 (p=0.233) respectively. Conclusion: Participation in yoga or aerobic exercise was associated with estimated improvements in verbal fluency compared to a non-active control group. Yoga and aerobic exercise may be promising approaches by which to promote cognitive function among older adults. Trial Registration: DRKS00015093, U1111-1217-4248.

BACKGROUND: A crucial goal of infectious disease surveillance is the early detection of epidemics, which is essential for disease control. In China, the current surveillance system is based on confirmed case reports. In rural China, it is not practical for health units to perform laboratory tests to confirm disease and people are more likely to get 'old' and emerging infectious diseases due to poor living conditions and closer contacts with wild animals and poultry. Syndromic surveillance, which collects non-specific syndromes before diagnosis, has great advantages in promoting the early detection of epidemics and reducing the necessities of disease confirmation. It will be especially effective for surveillance in resource poor settings. METHODS/DESIGN: This is a field experimental study. The experimental tool is an innovative electronic surveillance system, combining syndromic surveillance with the existing case report surveillance in four selected counties in China. In the added syndromic surveillance, three types of data are collected including patients' major symptoms from health clinics, pharmaceutical sales from pharmacies and absenteeism information from primary school. In order to evaluate the early warning capability of the new added syndromic surveillance, the timelines and validity of the alert signals will be analyzed in comparison with the traditional case reporting system. The acceptability, feasibility and economic evaluation of the whole integrated surveillance system will be conducted in a before and after study design. DISCUSSIONS: Although syndromic surveillance system has mostly been established in developed areas, there are opportunities and advantages of developing it in rural China. The project will contribute to knowledge, experience and evidence on the establishment of an integrated surveillance system, which aims to provide early warning of disease epidemics in developing countries.

OBJECTIVE: To compare the effects of yoga and aerobic exercise (AE) on wellbeing in physically inactive, but otherwise healthy older adults. A secondary objective was to assess and compare the frequency of adverse events associated with yoga and AE. DESIGN: Twelve-week, three-group, parallel randomized controlled trial with blinded follow-up assessment. INTERVENTIONS: Participants were supported to complete ≥ 3 Hatha yoga classes/week or ≥ 3 AE sessions/week. A wait-list control (WLC) group continued usual daily activities. MAIN OUTCOME MEASURE: Change in wellbeing, assessed using the Satisfaction with Life Scale (SWLS) and Life Satisfaction Index-Z (LSI),at baseline and at 12-week follow up. RESULTS: In total, 82 adults (mean age 72.5 years, range 65-85, 77% female) were recruited. Of these, 27 were randomized to yoga, 29 to aerobic exercise and 26 to wait-list control. Medium-magnitude treatment effects (Hedges' g) were seen for yoga versus WLC and AE versus WLC(SWLS, g = 0.65 and 0.56; LSI, g = 0.54 and 0.54, respectively). In per-protocol analyses, larger effect sizes were found (SWLS, g = 0.72 and 0.66; LSI, g = 0.76 and 0.76, respectively). Adverse events were less frequent in the yoga group (6/27; 22%) compared to AE (10/27; 37%). CONCLUSIONS: Among physically inactive older adults, participation in yoga or AE was associated with beneficial effects on subjective wellbeing when compared to a non-active control group. Yoga was associated with fewer injuries and may be especially suitable for older adults (DRKS 00015093).

BACKGROUND: In India, private pharmacies are ubiquitous yet critical establishments that facilitate community access to medicines. These are often the first points of treatment seeking in parts of India and other low income settings around the world. The characteristics of these pharmacies including their location, drug availability, human resources and infrastructure have not been studied before. Given the ubiquity and popularity of private pharmacies in India, such information would be useful to harness the potential of these pharmacies to deliver desirable public health outcomes, to facilitate regulation and to involve in initiatives pertaining to rational drug use. This study was a cross sectional survey that mapped private pharmacies in one district on a geographic information system and described relevant characteristics of these units. METHODS: This study of pharmacies was a part of larger cross sectional survey carried out to map all the health care providers in Ujjain district (population 1.9 million), Central India, on a geographic information system. Their location vis-à-vis formal providers of health services were studied. Other characteristics like human resources, infrastructure, clients and availability of tracer drugs were also surveyed. RESULTS: A total 475 private pharmacies were identified in the district. Three-quarter were in urban areas, where they were concentrated around physician practices. In rural areas, pharmacies were located along the main roads. A majority of pharmacies simultaneously retailed medicines from multiple systems of medicine. Tracer parenteral antibiotics and injectable steroids were available in 83.7% and 88.7% pharmacies respectively. The proportion of clients without prescription was 39.04%. Only 11.58% of staff had formal pharmacist qualifications. Power outages were a significant challenge. CONCLUSION: This is the first mapping of pharmacies & their characteristics in India. It provides evidence of the urban dominance and close relationship between healthcare provider location and pharmacy location. The implications of this relationship are discussed. The study reports a lack of qualified staff in the presence of a high proportion of clients attending without a prescription. The study highlights the need for the better implementation of regulation. Besides facilitating regulation & partnerships, the data also provides a sampling frame for future interventional studies on these pharmacies.

Importance: Cervical cancer is highly preventable but remains a common and deadly cancer in areas without screening programs. The creation of a diagnostic system to digitize Papanicolaou test samples and analyze them using a cloud-based deep learning system (DLS) may provide needed cervical cancer screening to resource-limited areas. Objective: To determine whether artificial intelligence-supported digital microscopy diagnostics can be implemented in a resource-limited setting and used for analysis of Papanicolaou tests. Design, Setting, and Participants: In this diagnostic study, cervical smears from 740 HIV-positive women aged between 18 and 64 years were collected between September 1, 2018, and September 30, 2019. The smears were digitized with a portable slide scanner, uploaded to a cloud server using mobile networks, and used to train and validate a DLS for the detection of atypical cervical cells. This single-center study was conducted at a local health care center in rural Kenya. Exposures: Detection of squamous cell atypia in the digital samples by analysis with the DLS. Main Outcomes and Measures: The accuracy of the DLS in the detection of low- and high-grade squamous intraepithelial lesions in Papanicolaou test whole-slide images. Results: Papanicolaou test results from 740 HIV-positive women (mean [SD] age, 41.8 [10.3] years) were collected. The DLS was trained using 350 whole-slide images and validated on 361 whole-slide images (average size, 100â¯387 × 47â¯560 pixels). For detection of cervical cellular atypia, sensitivities were 95.7% (95% CI, 85.5%-99.5%) and 100% (95% CI, 82.4%-100%), and specificities were 84.7% (95% CI, 80.2%-88.5%) and 78.4% (95% CI, 73.6%-82.4%), compared with the pathologist assessment of digital and physical slides, respectively. Areas under the receiver operating characteristic curve were 0.94 and 0.96, respectively. Negative predictive values were high (99%-100%), and accuracy was high, particularly for the detection of high-grade lesions. Interrater agreement was substantial compared with the pathologist assessment of digital slides (κ = 0.72) and fair compared with the assessment of glass slides (κ = 0.36). No samples that were classified as high grade by manual sample analysis had false-negative assessments by the DLS. Conclusions and Relevance: In this study, digital microscopy with artificial intelligence was implemented at a rural clinic and used to detect atypical cervical smears with a high sensitivity compared with visual sample analysis.

BACKGROUND: Poor adherence to antiretroviral treatment has been a public health challenge associated with the treatment of HIV. Although different adherence-supporting interventions have been reported, their long term feasibility in low income settings remains uncertain. Thus, there is a need to explore sustainable contextual adherence aids in such settings, and to test these using rigorous scientific designs. The current ubiquity of mobile phones in many resource-constrained settings, make it a contextually appropriate and relatively low cost means of supporting adherence. In India, mobile phones have wide usage and acceptability and are potentially feasible tools for enhancing adherence to medications. This paper presents the study protocol for a trial, to evaluate the influence of mobile phone reminders on adherence to first-line antiretroviral treatment in South India. METHODS/DESIGN: 600 treatment naïve patients eligible for first-line treatment as per the national antiretroviral treatment guidelines will be recruited into the trial at two clinics in South India. Patients will be randomized into control and intervention arms. The control arm will receive the standard of care; the intervention arm will receive the standard of care plus mobile phone reminders. Each reminder will take the form of an automated call and a picture message. Reminders will be delivered once a week, at a time chosen by the patient. Patients will be followed up for 24 months or till the primary outcome i.e. virological failure, is reached, whichever is earlier. Self-reported adherence is a secondary outcome. Analysis is by intention-to-treat. A cost-effectiveness study of the intervention will also be carried out. DISCUSSION: Stepping up telecommunications technology in resource-limited healthcare settings is a priority of the World Health Organization. The trial will evaluate if the use of mobile phone reminders can influence adherence to first-line antiretrovirals in an Indian context.

BACKGROUND: China incurs an extremely low treatment coverage of multidrug-resistant tuberculosis (MDR-TB). This study aimed to understand the experience of MDR-TB patients on quality of health care, and the clinical impact through an up to six-year follow-up. METHODS: Cohorts of MDR-TB patients were built in TB/MDR-TB designated hospitals in four regions of China from 2014 to 2015. Patients were followed up during treatment course, and yearly confirmation afterward until 2019. Delay in MDR-TB diagnosis and treatment was calculated upon bacteriological confirmation and treatment initiation. Risk factors for unfavourable outcomes were identified by multivariate logistic regression. RESULTS: Among 1168 bacteriological-positive TB patients identified from a 12-million population, 58 (5.0%) MDR-TB cases were detected. The median delay for MDR-TB diagnosis was 90.0 days, with 13.8% having a delay above 180.0 days. MDR-TB treatment was only recommended to 19 (32.8%) participants, while the rest continued with regimen for drug-susceptible TB. In MDR-TB treatment group, 36.8% achieved treatment success, while the others had incomplete treatment (21.1%), loss to follow-up (36.8%) and TB relapse (5.3%). For non-MDR-TB treatment group, 33.3% succeeded, 25.6% relapsed, 2.6% failed, 23.1% died, and 15.4% were lost to follow-up. Overall, only 35.7% (20/56) of detected MDR-TB patients had favourable outcomes and higher education level was positively associated with it (adjusted odds ratio [aOR]: 3.60, 95% confidence interval [CI]: 1.04-12.5). CONCLUSIONS: A large proportion of patients did not receive MDR-TB treatment and had unfavourable outcomes. Delayed MDR-TB diagnosis resulted in poor quality of MDR-TB care. Rapid diagnosis, regulated patient management and high-quality MDR-TB treatment should be enhanced in China.

This study is set on the background of a randomized control trial (RCT) in which intervention was carried to observe the effects of yoga/light exercise on the improvement in health and well-being among the elderly population. A longitudinal qualitative study was conducted as part of RCT interventions to explore the experience of the elderly practicing yoga/light exercise in relation to sedentary behavior in the Ujjain district of Madhya Pradesh, India. Participants of the RCT were selected for this study. Eighteen focus group discussions were conducted-six during each phase of RCT interventions (before, during, and after). The findings regarding motivating and demotivating factors in various phases of intervention were presented in three categories: experience and perception of the effects of yoga/light exercise on sedentary behavior (1) before, (2) during, and (3) after intervention. This study explores the positive effect of yoga/light exercise on sedentary behavior and subjective well-being on the elderly population. They were recognized to have undergone changes in their physical and emotional well-being by consistently practicing yoga/light exercise. The main driving factors were periodic health check-ups and the encouragement of qualified trainers without any cost. This study concludes with the notion that these interventions should be encouraged in the community to use physical exercise as a method to better control the physical and social effects of aging.
