COVID-19 vaccination in Laos has been affected by challenges in reaching the whole population and preexisting mistrust in the health system. Vaccination rates are low among the Hmong, whose healing epistemologies are rooted in animism and Christianity, while most healthcare staff are from the lowland Buddhist majority. However, local notions of immunity and religious practices are not the main factors influencing confidence in vaccines, as these are flexible and pragmatic in incorporating different approaches to curing illness. Instead, the root causes are patterns of mistrust and inequity enacted through Hmong peoples' experiences with health services. An innovative government-led initiative focusing on trust-building and local ownership through relational community engagement, utilizing existing village, family, ethnic, and religious structures and promoting effective communication and cultural sensitivity led to a rapid increase in vaccine uptake. Trust in vaccines is therefore not an abstract concept but highly relational, and so can be intentionally developed. [ABSTRACT FROM AUTHOR]

The mammalian skeleton stores calcium and phosphate ions in bone matrix. Osteocytes in osteocyte lacunae extend numerous dendrites into canaliculi less than a micron in diameter and which are distributed throughout bone matrix. Although osteoclasts are the primary bone-resorbing cells, osteocytes also reportedly dissolve hydroxyapatite at peri-lacunar bone matrix. However, robust three-dimensional evidence for peri-canalicular bone mineral dissolution has been lacking. Here we applied a previously reported Talbot-defocus multiscan tomography method for synchrotron X-ray microscopy and analyzed the degree of bone mineralization in mouse cortical bone around the lacuno–canalicular network, which is connected both to blood vessels and the peri- and endosteum. We detected cylindrical low mineral density regions spreading around canaliculi derived from a subset of osteocytes. Transmission electron microscopy revealed both intact and demineralized bone matrix around the canaliculus. Peri-canalicular low mineral density regions were also observed in osteopetrotic mice lacking osteoclasts, indicating that osteoclasts are dispensable for peri-canalicular demineralization. These data suggest demineralization can occur from within bone through the canalicular system, and that peri-canalicular demineralization occurs not uniformly but directed by individual osteocytes. Blockade of peri-canalicular demineralization may be a therapeutic strategy to increase bone mass and quality. [ABSTRACT FROM AUTHOR]

Analytical technologies of ultrasmall volume liquid, in particular femtoliter to attoliter liquid, is essential for single-cell and single-molecule analysis, which is becoming highly important in biology and medical diagnosis. Nanofluidic chips will be a powerful tool to realize chemical processes for such a small volume sample. However, a technical challenge exists in fluidic control, which is femtoliter to attoliter liquid generation in air and handling for further chemical analysis. Integrating mechanical valves fabricated by MEMS (microelectric mechanical systems) technology into nanofluidic channels is difficult. Here, we propose a nonmechanical valve, which is a Laplace nanovalve. For this purpose, a nanopillar array was embedded in a nanochannel using a two-step electron beam lithography and dry-etching process. The nanostructure allowed precise wettability patterning with a resolution below 100 nm, which was difficult by photochemical wettability patterning due to the optical diffraction. The basic principle of the Laplace nanovalve was verified, and a 1.7 fL droplet (water in air) was successfully generated and handled for the first time. [ABSTRACT FROM AUTHOR]

Background: Disruptions in essential health services during the COVID-19 pandemic have been reported in several countries. Yet, patterns in health service disruption according to country responses remain unclear. In this paper, we investigate associations between the stringency of COVID-19 containment policies and disruptions in 31 health services in 10 low- middle- and high-income countries in 2020. Methods: Using routine health information systems and administrative data from 10 countries (Chile, Ethiopia, Ghana, Haiti, Lao People's Democratic Republic, Mexico, Nepal, South Africa, South Korea, and Thailand) we estimated health service disruptions for the period of April to December 2020 by dividing monthly service provision at national levels by the average service provision in the 15 months pre-COVID (January 2019-March 2020). We used the Oxford COVID-19 Government Response Tracker (OxCGRT) index and multi-level linear regression analyses to assess associations between the stringency of restrictions and health service disruptions over nine months. We extended the analysis by examining associations between 11 individual containment or closure policies and health service disruptions. Models were adjusted for COVID caseload, health service category and country GDP and included robust standard errors. Findings: Chronic disease care was among the most affected services. Regression analyses revealed that a 10% increase in the mean stringency index was associated with a 3.3 percentage-point (95% CI -3.9, -2.7) reduction in relative service volumes. Among individual policies, curfews, and the presence of a state of emergency, had the largest coefficients and were associated with 14.1 (95% CI -19.6, 8.7) and 10.7 (95% CI -12.7, -8.7) percentage-point lower relative service volumes, respectively. In contrast, number of COVID-19 cases in 2020 was not associated with health service disruptions in any model. Conclusions: Although containment policies were crucial in reducing COVID-19 mortality in many contexts, it is important to consider the indirect effects of these restrictions. Strategies to improve the resilience of health systems should be designed to ensure that populations can continue accessing essential health care despite the presence of containment policies during future infectious disease outbreaks.

Since the 2008 publication of the reports of the Commission on Social Determinants of Health and its nine knowledge networks, substantial research has been undertaken to document and describe health inequities. The COVID-19 pandemic has underscored the need for a deeper understanding of, and broader action on, the social determinants of health. Building on this unique and critical opportunity, the World Health Organization is steering a multi-country Initiative to reduce health inequities through an action-learning process in 'Pathfinder' countries. The Initiative aims to develop replicable and reliable models and practices that can be adopted by WHO offices and UN staff to address the social determinants of health to advance health equity. This paper provides an overview of the Initiative by describing its broad theory of change and work undertaken in three regions and six Pathfinder countries in its first year-and-a-half. Participants engaged in the Initiative describe results of early country dialogues and promising entry points for implementation that involve model, network and capacity building. The insights communicated through this note from the field will be of interest for others aiming to advance health equity through taking action on the social determinants of health, in particular as regards structural determinants.

Trust remains a critical concept in healthcare provision, but little is known about the ability of health policy and interventions to stimulate more trusting relationships between communities and the health system. The CONNECT (Community Network Engagement for Essential Healthcare and COVID-19 Responses Through Trust) Initiative in Lao PDR provided an opportunity to assess the community-level impact of a trust-building community engagement approach. A mixed-method process evaluation was implemented from 10/2022–12/2023 among 14 diverse case study communities in four provinces across Lao PDR. Data collection involved two rounds of census surveys (3161 observations incl. panel data from 618 individuals) including an 8-item trust scale, 50 semi-structured interviews with villagers, and 50 contextualizing key informant interviews. The two data collection rounds were implemented before and three months after village-based CONNECT activities and helped discern impacts among activity participants, indirectly exposed villagers, and unexposed villagers in a difference-in-difference analysis. Stakeholders attested strong support for the CONNECT Initiative although community-level retention of trust-related themes from the activities was limited. Quantitative data nevertheless showed that, at endline, the 8-item trust index (from [–8 to +8]) increased by 0.95 points from 4.44 to 5.39 and all trust indicators were universally higher. Difference-in-difference analysis showed that villagers exposed to the CONNECT activities had a 1.02-index-point higher trust index compared to unexposed villagers. Trust impacts improved gradually over time and were relatively more pronounced among men and ethnic minority groups. The CONNECT Initiative had considerable direct and systemic effects on community members' trust in their local health centers in the short term, which arose from strong stakeholder mobilization and gradual institutional learning. Relational community engagement approaches have the potential to create important synergies in health policy and broader cross-sectorial strategies, but also require contextual grounding to identify locally relevant dimensions of trust. • Community engagement holds promise for building trust in healthcare • Study provides short-term mixed-method evaluation evidence from rural Lao PDR • Trust improved strongly and consistently across all dimensions • Systemic and direct impacts underline success of relational community engagement • Trust-building approaches require strong stakeholder support and local grounding [ABSTRACT FROM AUTHOR]

Background: Thousands of neonatal deaths are expected to be averted by introducing the Early Essential Newborn Care (EENC) in the Western Pacific Region. In Lao People's Democratic Republic (Lao PDR), the government adopted the EENC programme and expanded it to district hospitals. With the expansion, maintaining the quality of EENC has become difficult for the government. Methods: A cluster randomised controlled trial with four strata based on province and history of EENC coaching was implemented to evaluate the effectiveness of self-managed continuous monitoring compared with supervisory visit in Lao PDR between 20 July 2017 and 2 April 2019. Health workers who were routinely involved in maternity care were recruited from 15 district hospitals in Huaphanh (HP) and Xiangkhouang (XK) provinces. The primary endpoint was the score on the determinants of EENC performance measured by the Theory of Planned Behaviour (TPB). Secondary endpoints were set as the knowledge and skill scores. A linear mixed-effects model was applied to test the effects of intervention over time on the endpoints. Results: Among 198 recruited health workers, 46 (23.2%) did not complete the final evaluation. TPB scores were 180.9 [Standard Deviation: SD 38.6] and 182.5 [SD 37.7] at baseline and 192.3 [SD 30.1] and 192.3 [SD 28.4] at the final evaluation in the intervention and control groups, respectively. There was no significant difference in changes between the groups in the adjusted model (2.4, p = 0.650). Interviews with participants revealed that district hospitals in HP regularly conducted peer reviews and feedback meetings, while few hospitals did in XK. Accordingly, in stratified analyses, the TPB score in the intervention group significantly increased in HP (15.5, p = 0.017) but largely declined in XK (− 17.7, p = 0.047) compared to the control group after adjusting for covariates. Skill scores declined sharper in the intervention group in XK (− 8.78, p = 0.026), particularly in the practice of managing nonbreathing babies. Conclusions: The study indicates that self-managed continuous monitoring is effective in improving behaviour among district health workers; however, additional measures are necessary to support its proper implementation. To maintain resuscitation skills, repeated practice is necessary. Trial registration: This trial was registered at UMIN Clinical Trials Registry on 15/6/2017. Registration number is UMIN000027794.

Background: The provision of quality health services has been a global priority to reduce neonatal and maternal deaths. In Lao People's Democratic Republic (Lao PDR), the coverage of institutional childbirth stayed at a low level regardless of a sharp increase in the coverage of antenatal care (ANC) and fee exemption. The aim of the present study was to preliminary explore factors associated with increased institutional childbirth and the association between ANC attendance and maternal knowledge among women in rural villages of Lao PDR.Methods: A secondary data analysis was conducted using data collected through a pilot survey in Sekong province in Lao PDR. The study participants were women with children under 5 years of age in villages within 10 km (km) from health centers staffed with skilled birth attendants. Data were collected via a face-to-face interview using a semi-structured questionnaire and were analysed using logistic regression models to estimate odds ratios (ORs) and their 95% confidence intervals (CIs) for having institutional childbirth in relation to potential factors.Results: A total of 302 women, 203 (67.2%) of whom gave birth at a health facility. 277 (91.7%) attended ANC at least once. Sixty-nine women (22.9%) had received no formal education, 272 (90.1%) were of an ethnic minority, 174 (57.6%) were unwaged and 99 (32.8%) lived more than 6 km from the nearest health facility. 51 (16.6%) did not know about birth complications at interview. Institutional childbirth was negatively associated with a lack of maternal knowledge about birth complications (OR, 0.27; 95% Cl, 0.14-0.54) after adjusting for covariates. Although there were few women who did not received ANC, the results suggested ANC might not be associated with maternal knowledge about birth complications (OR, 1.87; 95% Cl, 0.43-8.12).Conclusions: The present study suggests that maternal knowledge about birth complications is an important factor in increasing the institutional childbirth in rural villages of Lao PDR where majority of residents were ethnic minority. Improving quality of ANC and attitude among health care providers may be key to increasing health-seeking behavior. However, further research is needed to understand factors influencing choice of place of childbirth. [ABSTRACT FROM AUTHOR]

Abstract: Trabecular bone microfracture pathogenesis and associated healing processes are not well understood. We analyzed the microcalluses that form subsequent to microfractures in patients with osteoporosis (OP) using synchrotron radiation micro CT (SRCT). Subchondral bone columns were extracted from the femoral heads of 11 female patients with a femoral neck fracture. SRCT scanning was performed with 5.9×5.9×5.9μm3 voxel size and the microcallus number was measured in a 5-mm cubic subchondral bone region. The trabecular bone microstructure was measured and its relationship to the microcallus number was analyzed. In addition, the degree of mineralization of the microcallus region and that of the rest of the trabecular bone were measured and compared. Microcallus formations were detected in all cases, with a mean microcallus number of 4.9 (range, 2–11). The microcallus number had a significantly negative correlation with bone volume fraction (BV/TV), trabecular thickness (Tb.Th), and degree of mineralization, and had a positive correlation with specific bone surface (BS/BV). The degree of mineralization of the microcallus region was lower than that of the rest of the trabecular bone and had a wider range of values. Microcallus formations were frequently detected in patients with OP, and more prevalent in the bone with thinner trabeculae, suggesting microfractures might occur due to activities of daily living as the OP progresses. The degree of mineralization of microcallus might represent the process of bone healing from immature woven bone to mature trabecular bone. [Copyright &y& Elsevier]

Background: Reduction in neonatal deaths has been a major challenge globally. To prevent neonatal deaths, improvements in newborn care have been promoted worldwide. The World Health Organization Western Pacific Regional Office has been promoting the Early Essential Newborn Care (EENC), a package of specific simple and cost-effective interventions, in their region. However, mere introduction of EENC cannot reduce neonatal deaths unless quality of care is ensured. In Lao PDR, the government introduced self-managed continuous monitoring as a sustainable way to improve the quality of care described in the EENC.Methods: A clustered randomized controlled trial was designed to compare the effectiveness of self-managed continuous monitoring with external supervisory visits to monitor health workers' satisfactory EENC performance and their knowledge and skills related to the EENC in Lao PDR. Determinants of EENC performance will be measured with a structured questionnaire developed based on the Theory of Planned Behaviour, which predicts future behaviour. During self-managed continuous monitoring activities, health workers in each district hospital will conduct periodical peer reviews and feedback sessions. Fifteen district hospitals will be randomly allocated into the self-managed continuous monitoring (intervention) and the supervision (control) groups. Fifteen health workers routinely involved in maternity and newborn care including physicians, midwives and other health staff will be recruited from each hospital (effect size 0.6, intra-cluster correlation coefficient 0.06, 5% alpha error and 80% power). We will compare the change in the mean score of the determinants before and one year after randomisation between the two groups. We will also compare the retention of knowledge and skills related to the EENC between the two groups. The expected enrolment period is July 20th, 2017 to July 20th, 2018.Discussion: This is the first cluster randomized trial to evaluate a self-managed continuous monitoring system for quality maintenance of newborn care in a resource-limited country. This research is conducted in collaboration with the Ministry of Health and international organizations; therefore, if effective, this intervention would be applied in larger areas of the country and the region.Trial Registration: This trial was registered at UMIN-CTR on 15th of June, 2017. Registration number is UMIN000027794 . [ABSTRACT FROM AUTHOR]
