Access to community-based reproductive health services and incidence of low birthweight delivery among refugee and displaced mothers: a retrospective study in the Thailand-Myanmar border region.

OBJECTIVES: Over 2.4 million people have been displaced within the Thailand-Myanmar border region since 1988. The efficacy of community-driven health models within displaced populations is largely unstudied. Here, we examined the relationship between maternal healthcare access and delivery outcomes to evaluate the impact of community-provided health services for marginalised populations. SETTING: Study setting was the Thailand-Myanmar border region's single largest provider of reproductive health services to displaced mothers. PARTICIPANTS: All women who had a delivery (n=34 240) between 2008 and 2019 at the study clinic were included in the performed retrospective analyses. PRIMARY AND SECONDARY OUTCOME MEASURES: Low birth weight was measured as the study outcome to understand the relationship between antenatal care access, family planning service utilisation, demographics and healthy deliveries. RESULTS: First trimester (OR=0.86; 95% CI=0.81 to 0.91) and second trimester (OR=0.86; 95% CI=0.83 to 0.90) antenatal care visits emerged as independent protective factors against low birthweight delivery, as did prior utilisation of family planning services (OR=0.82; 95% CI=0.73 to 0.92). Additionally, advanced maternal age (OR=1.36; 95% CI=1.21 to 1.52) and teenage pregnancy (OR=1.27, 95% CI=1.13 to 1.42) were notable risk factors, while maternal gravidity (OR=0.914; 95% CI=0.89 to 0.94) displayed a protective effect against low birth weight. CONCLUSION: Access to community-delivered maternal health services is strongly associated with positive delivery outcomes among displaced mothers. This study calls for further inquiry into how to best engage migrant and refugee populations in their own reproductive healthcare, in order to develop resilient models of care for a growing displaced population globally.

Malaria Case Detection Among Mobile Populations and Migrant Workers in Myanmar: Comparison of 3 Service Delivery Approaches.

BACKGROUND: Mobile populations and migrant workers are a key population to containing the spread of artemisinin-resistant malaria found in the border areas between Cambodia, Myanmar, and Thailand. Migrants often have limited knowledge of public health, including malaria, services in the area, and many seek care from unregulated, private vendors. METHODS: Between October 2012 and August 2016, we implemented malaria case finding and treatment in Tanintharyi Region, Kayin State, and Rakhine State of Myanmar through 3 entry points: village malaria workers (VMWs), mobile malaria clinics, and screening points. A total of 1,000 VMWs provided passive case detection and treatment services to residents in malaria-endemic villages. Active case finding through mobile malaria clinics was conducted by staff in 354 remote villages and work sites, where regular monitoring and supervision of VMWs would be difficult to maintain. Malaria screening points were a hybrid combination of active and passive case finding in which screening points were set up at fixed locations in Tanintharyi Region and Kayin State, such as bus stops, ferry docks, or informal border crossing points, and migrants entering into or departing from endemic areas could voluntarily receive malaria testing and treatment. Using routine monitoring data, we assessed and compared the malaria positive rate-the number of positive malaria cases out of those tested-across the 3 approaches as an indication of the programmatic effectiveness in identifying malaria cases in the population. Most testing was conducted with rapid diagnostic tests. RESULTS: Mobile teams (169,859) and VMWs (157,048) tested a higher number of community members than screening points (3,676) as they covered a wider geographical area. However, the malaria positive rate was higher among VMWs (7.29%) and screening points (7.10%) than mobile teams (2.64%). VMWs were located in hard-to-access areas that have higher malaria prevalence and are difficult to reach by vehicle while screening points specifically targeted mobile populations and migrant workers. Mobile teams also screened non-fever patients during their visits, which may explain their lower malaria positive rate. CONCLUSIONS: A combination of malaria testing approaches helps achieve both maximum reach and high case finding as it allows access to a range of migrant communities and provides an opportunity for continuity of service delivery as the migrants travel to their destinations.

Efficacy and effectiveness of dihydroartemisinin-piperaquine versus artesunate-mefloquine in falciparum malaria: an open-label randomised comparison.

BACKGROUND: Artemisinin-based combinations are judged the best treatments for multidrug-resistant Plasmodium falciparum malaria. Artesunate-mefloquine is widely recommended in southeast Asia, but its high cost and tolerability profile remain obstacles to widespread deployment. To assess whether dihydroartemisinin-piperaquine is a suitable alternative to artesunate-mefloquine, we compared the safety, tolerability, efficacy, and effectiveness of the two regimens for the treatment of uncomplicated falciparum in western Myanmar (Burma). METHODS: We did an open randomised comparison of 3-day regimens of artesunate-mefloquine (12/25 mg/kg) versus dihydroartemisinin-piperaquine (6.3/50 mg/kg) for the treatment of children aged 1 year or older and in adults with uncomplicated falciparum malaria in Rakhine State, western Myanmar. Within each group, patients were randomly assigned supervised or non-supervised treatment. The primary endpoint was the PCR-confirmed parasitological failure rate by day 42. Failure rates at day 42 were estimated by Kaplan-Meier survival analysis. This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN27914471. FINDINGS: Of 652 patients enrolled, 327 were assigned dihydroartemisinin-piperaquine (156 supervised and 171 not supervised), and 325 artesunate-mefloquine (162 and 163, respectively). 16 patients were lost to follow-up, and one patient died 22 days after receiving dihydroartemisinin-piperaquine. Recrudescent parasitaemias were confirmed in only two patients; the day 42 failure rate was 0.6% (95% CI 0.2-2.5) for dihydroartemisinin-piperaquine and 0 (0-1.2) for artesunate-mefloquine. Whole-blood piperaquine concentrations at day 7 were similar for patients with observed and non-observed dihydroartemisinin-piperaquine treatment. Gametocytaemia developed more frequently in patients who had received dihydroartemisinin-piperaquine than in those on artesunate-mefloquine: day 7, 18 (10%) of 188 versus five (2%) of 218; relative risk 4.2 (1.6-11.0) p=0.011. INTERPRETATION: Dihydroartemisinin-piperaquine is a highly efficacious and inexpensive treatment of multidrug-resistant falciparum malaria and is well tolerated by all age groups. The effectiveness of the unsupervised treatment, as in the usual context of use, equalled its supervised efficacy, indicating good adherence without supervision. Dihydroartemisinin-piperaquine is a good alternative to artesunate-mefloquine.

Follow-up of tibialis posterior transfer surgery (TPT) for drop-foot in leprosy.

Prevention of Disability (POD) service needs to be expanded for future reducing the leprosy burden. Tibialis Posterior Transfer Surgery (TPT) is an established procedure and relatively easy to do at district level general hospitals. It can protect further damages of affected foot and consequently reduce patient's social burden as well. Totally 70 TPT surgeries were done during a joint project of JICA on leprosy control and basic health service in Myanmar for training purpose (Jan/2002-Jan/2006). A follow-up assessment was done for exploring the effectiveness of foot drop surgery, in Nov/2006 at 9-selected townships in Mid-Myanmar. 33 cases (Male 22, Female 11) were reviewed and the mean of follow up period was 29.1 months (SD=7.1, 10-48 months). Total results were; good: 25 cases (76%), fair: 4 cases (12%) and poor: 4 cases (12%). In good and fair cases, patients were satisfied with the results and TPT improved the QOL of patients. In almost all cases (32/33, 97%) after TPT, patients are free from plantar ulcer. Most serious complication of operation (4 cases, 12%) identified was inversion deformity due to loosed tension of lateral tail of grafted TP tendon sutured to Extensor Digitorum Longus. From the results of TPT surgery follow-up, it can benefit much to the patients if resources permit to make it as a routine service in more places.

Optimising operational use of artesunate-mefloquine: a randomised comparison of four treatment regimens.

A randomised trial was conducted in adults and children (> 1 year old) with acute falciparum malaria in Western Myanmar to compare the operational effectiveness of 4 different artesunate-mefloquine combinations. All regimens were well tolerated. During 42 days follow-up polymerase chain reaction genotyping-confirmed recrudescence occurred in 11 of 187 (5.9%) patients who received observed single low-dose mefloquine (15 mg/kg) and artesunate (4 mg/kg), 7 of 192 (3.6%) patients following observed single high-dose mefloquine (25 mg/kg) and artesunate (4 mg/kg), 7 of 180 (3.9%) patients following observed artesunate 4 mg/kg on day 0 plus self-administered mefloquine 15 mg/kg on day 1 and 10 mg/kg on day 2 with artesunate 4 mg/kg/day on day 1 and 2, and none of 177 patients who received this 3 d regimen under direct observation (P = 0.01). Compared with 3 d treatment regimens, single dose treatments were followed by significantly more P vivax infections during the 42 d follow-up (P = 0.009). Post treatment anaemia (haemoglobin < 10 g/dL) was reduced by the 3 d regimens. Gametocyte appearance was low with all 4 regimens. Single dose observed mefloquine-artesunate regimens were very effective, but the 3 d artesunate-mefloquine regimen is the best treatment for acute falciparum malaria in Western Myanmar. Active measures to ensure absorption and improve adherence will be necessary to realise this advantage operationally.

Mekong malaria. II. Update of malaria, multi-drug resistance and economic development in the Mekong region of Southeast Asia.

In an expansion of the first Mekong Malaria monograph published in 1999, this second monograph updates the malaria database in the countries comprising the Mekong region of Southeast Asia. The update adds another 3 years' information to cover cumulative data from the 6 Mekong countries (Cambodia, China/Yunnan, Lao PDR, Myanmar, Thailand, Viet Nam) for the six-year period 1999-2001. The objective is to generate a more comprehensive regional perspective in what is a global epicenter of drug resistant falciparum malaria, in order to improve malaria control on a regional basis in the context of social and economic change. The further application of geographical information systems (GIS) to the analysis has underscored the overall asymmetry of disease patterns in the region, with increased emphasis on population mobility in disease spread. Of great importance is the continuing expansion of resistance of P. falciparum to antimalarial drugs in common use and the increasing employment of differing drug combinations as a result. The variation in drug policy among the 6 countries still represents a major obstacle to the institution of region-wide restrictions on drug misuse. An important step forward has been the establishment of 36 sentinel sites throughout the 6 countries, with the objective of standardizing the drug monitoring process; while not all sentinel sites are fully operational yet, the initial implementation has already given encouraging results in relation to disease monitoring. Some decreases in malaria mortality have been recorded. The disease patterns delineated by GIS are particularly instructive when focused on inter-country distribution, which is where more local collaborative effort can be made to rationalize resource utilization and policy development. Placing disease data in the context of socio-economic trends within and between countries serves to further identify the needs and the potential for placing emphasis on resource rationalization on a regional basis. Despite the difficulties, the 6-year time frame represented in this monograph gives confidence that the now well established collaboration is becoming a major factor in improving malaria control on a regional basis and hopefully redressing to a substantial degree the key problem of spread of drug resistance regionally and eventually globally.

Promoting antenatal care services for early detection of pre-eclampsia.

A prospective, quasi-experimental study was carried out in 2009 at urban health centres (UHCs) of five townships of Mandalay, Myanmar, to improve the skill of midwives (MWs) in diagnosis and referral of pre-eclampsia (PE) from UHC to the Central Women's Hospital (CWH) and to enhance the supervision of midwives by lady health visitors (LHVs). The intervention was training on quality antenatal care focusing on PE using an updated training manual. Altogether, 75 health care providers (MWs & LHVs) participated. In this study, data were extracted from patient registers and monthly reports of UHCs and CWH. Interviewers were trained regarding the conduct of semi-structured questionnaires to elicit knowledge and to use checklists in observation of skills in screening of PE, measuring blood pressure and urine protein (dipstick test). A guide for LHVs was also used to obtain data, and data was collected six months prior to and after the intervention. Significant improvements from baseline to endline survey occurred in the knowledge (p<0.001) and skill levels (p<0.001) including skills for screening, measuring blood pressure and urine protein. At CWH, there was an increase in referred cases of PE after the intervention, from 1.25% to 2.56% (p<0.001). In conclusion, this study highlights the early detection of pre-eclampsia by widespread use of quality antenatal care, education and training of health-care providers to improve their performance and increase human resources for health care, in order to enable women in our society to have healthy pregnancies and healthy babies.

An approach to health system strengthening in the Union of Myanmar.

OBJECTIVES: In 2007 and 2008, Myanmar developed a health system strengthening (HSS) strategy and proposal through funding support from the Global Alliance for Vaccines and Immunization (GAVI). The aim of this paper is to identify critical success factors in the development of the HSS strategy in Myanmar. METHODS: The main source of information for this review includes international and national literature, and participant observation by the authors in the health systems analysis and HSS strategy development in Myanmar between 2007 and 2009. RESULTS: Critical success factors in the development of the HSS strategy included evidence-based development of the strategy through a sector analysis, and a long-term approach to strategy development with wide stakeholder participation. This contributed to important strategy breakthroughs in the areas of health planning, health financing, human resource management and civil society partnerships. CONCLUSION: Implementation of the HSS strategy in Myanmar should position the MOH and partners well to implement challenging system reforms in the areas of health planning, financing and human resource management in the coming years, as well as support more coordinated efforts for relief and recovery effort following the Nargis natural disaster in 2008. These innovations in Myanmar, with evidence of similar breakthroughs in other countries of the Asian region including North Korea, Cambodia, Nepal and Sri Lanka, provides promising evidence of the potential of the HSS approach as an emerging health development paradigm, particularly in relation to responding to the issue of "within country" inequities in access to health care.

Comparison of chloroquine, sulfadoxine/pyrimethamine, mefloquine and mefloquine-artesunate for the treatment of falciparum malaria in Kachin State, North Myanmar.

Multi-drug resistant falciparum malaria is widespread in Asia. In Thailand, Cambodia and Vietnam the national protocols have changed largely to artesunate combined treatment regimens but elsewhere in East and South Asia chloroquine (CQ) and sulfadoxine-pyrimethamine (SP) are still widely recommended by national malaria control programmes. In Kachin State, northern Myanmar, an area of low seasonal malaria transmission, the efficacy of CQ (25 mg base/kg) and SP (1.25/25 mg/kg), the nationally recommended treatments at the time, were compared with mefloquine alone (M; 15 mg base/kg) and mefloquine combined with artesunate (MA; 15:4 mg/kg). An open randomized controlled trial enrolled 316 patients with uncomplicated Plasmodium falciparum malaria, stratified prospectively into three age-groups. Early treatment failures (ETF) occurred in 41% (32/78) of CQ treated patients and in 24% of patients treated with SP (18/75). In young children the ETF rates were 87% after CQ and 35% after SP. Four children (two CQ, two SP) developed symptoms of cerebral malaria within 3 days after treatment. By day 42, failure rates (uncorrected for reinfections) had increased to 79% for CQ and 81% for SP. ETF rates were 2.5% after treatment with M and 3.9% after treatment with MA (P > 0.2). Overall uncorrected treatment failure rates at day 42 following M and MA were 23% and 21%, respectively. Chloroquine and SP are completely ineffective for the treatment of falciparum malaria in northern Myanmar. Mefloquine treatment is much more effective, but three day combination regimens with artesunate will be needed for optimum efficacy and protection against resistance.
