    Oral health care during pregnancy to prevent preterm birth and low birth weight: study protocol for a randomized controlled trial

    by Junko Yasuoka, Yohei Takeshita, Shunsuke Okada, Prodhan Md Rubayet Alam, Akira Shibanuma, Keiko Nanishi, Yoko Sato, Zahid Hossain, Musfiqa Aman, Fahmida Karim, et al.

    Background: Periodontal disease during pregnancy has been associated with an increased risk of preterm birth (PTB) and low birth weight (LBW). However, most previous interventional studies have reported that scaling and root planing (SRP), a form of basic periodontal treatment, is insufficient to effectively prevent PTB and LBW. Recent systematic reviews and meta-analyses suggest that combining SRP with routine use of chlorhexidine gluconate (CHG) mouthwash may reduce the risk of these adverse birth outcomes by approximately half. This study will be among the first randomized controlled trials (RCTs) to evaluate the potential synergistic effects of this combined approach on improving birth outcomes. Methods: This multi-center, three-arm RCT will be conducted at two hospitals in Dhaka and Bogura, Bangladesh, between April 2025 and September 2026. A total of 480 pregnant women less than 20 weeks’ gestation attending antenatal checkups will be recruited. Participants diagnosed with periodontal disease will be randomly assigned to either an intervention group or a positive control group. Participants without periodontal disease will be assigned to a negative control group. The intervention consists of SRP combined with continued use of CHG mouthwash throughout pregnancy. The primary outcome will be the rate of PTB. Secondary outcomes include the birth weight of the newborn baby, maternal periodontal status, and oral health-related quality of life (OHRQoL). Effectiveness will be assessed by comparing outcomes across the study groups. Discussion: The oral health intervention is expected to improve both birth outcomes and maternal oral health. Demonstrating its effectiveness in a real-world setting may support the integration of oral health care into broader maternal, neonatal, and child health strategies, particularly in resource-limited settings.

    Status and Challenges of Medical History Taking in Bangladesh and an Affordable Digital Solution to Tackle Them

    by Forhad Hossain, Mohamed Mehfoud Bouh, Moshiur Rahman, Faiz Shah, Tsunenori Mine, Rafiqul Islam, Naoki Nakashima, Ashir Ahmed

    Capturing patients’ medical histories significantly influences clinical decisions. Errors in this process lead to clinical errors, which increase costs and dissatisfaction among physicians and patients. Physicians in developing countries are overloaded with patients and cannot always follow the proper history-taking procedure. The challenges have been acknowledged; however, a comprehensive understanding of the status and the remedies has remained unexplored. This paper aims to investigate the workload, history-taking challenges, and the willingness of the physicians to accept digital solutions. A cross-sectional online survey was conducted on 104 physicians across Bangladesh, featuring 22 questions regarding their professional environment, workload, digitization status of health records, challenges in history taking, and attitudes toward adopting digital solutions for managing patient histories; 92.67% of the physicians face high workloads, 88.46% struggle in medical history taking, and only 4.81% use digital medical records. About 70% struggle to complete the necessary history-taking steps, emphasizing the urgent need for solutions. A novel visualization system, the Smart Health Gantt Chart (SHGC), has been introduced for their instant feedback. A total of 93.27% of physicians expressed their willingness to use such a system. The proposed SHGC has the potential to enhance healthcare efficiency in developing nations, benefit physicians, and improve patient-centered care.

    Concept of Micro Healthcare Entrepreneurship (MHE) to Facilitate Universal Health Coverage (UHC): Prospects and Challenges

    by Forhad Hossain, Rafiqul Islam, Takuzo Osugi, Faiz Shah, Tsunenori Mine, Naoki Nakashima, Ashir Ahmed

    In the pursuit of Universal Health Coverage (UHC), developing countries with limited resources face significant hurdles. Traditional top-down approaches, spearheaded by governments, often entail lengthy planning periods and substantial costs to reach underserved communities. This paper proposes a bottom-up, cost-effective, and preventive approach aimed at empowering local human resources and using advanced technology. We call it the Micro Healthcare Entrepreneurship (MHE) model. The MHE model comprises four primary components: (1) utilization of local human resources, (2) disruptive healthcare technology, (3) continuous training, and (4) available funds. Extensive testing of the digital health and social business elements across diverse contexts underscores their efficacy. Furthermore, the viability of social business funds has been established. To solicit feedback and refine the MHE concept, three workshops, conducted in phases, engaged 60 community healthcare service providers. This paper elucidates both the potential advantages and the challenges inherent in implementing the MHE model. By shifting the paradigm toward grassroots empowerment and leveraging existing community assets, this approach offers promise in advancing healthcare accessibility and sustainability in resource-constrained settings to achieve UHC.

    Performance Evaluation of the Commonly-Used Portable Cholesterol Sensors for Telehealth Services in the Unreached Communities

    by Rafiqul Islam, Saori To, Rieko Izukura, Yoko Sato, Mariko Nishikitani, Kimiyo Kikuchi, Fumihiko Yokota, Subaru Ikeda, Rakibul Islam, Ashir Ahmed, et al.

    Portable medical sensors play an important role in healthcare services, especially in rural communities. Many telehealth systems use these devices for providing patients' vital information from a distance to remote doctors. Erroneous data will not only mislead the remote doctor for correct diagnosis but it will cause health threats to these unreached community people. Therefore, it is very important to identify good sensors with an acceptable level of accuracy but within the affordable price of the available sensors in the market. This study aims to identify quality portable cholesterol sensors with high accuracy with the reference of the Japanese clinical pathology laboratory as a gold standard. We have considered cholesterol sensors that measure total cholesterol for this study that are commonly used in the developing countries of Asia. We found that out of four, three of them were very much erroneous and cannot be recommended even for primary healthcare.

    Potential Improvement in a Portable Health Clinic for Community Health Service to Control Non-Communicable Diseases in Indonesia

    by Hanifah Wulandari, Lutfan Lazuardi, Nurholis Majid, Fumihiko Yokota, Guardian Yoki Sanjaya, Tika Sari Dewi, Andreasta Meliala, Rafiqul Islam, Naoki Nakashima

    The COVID-19 pandemic has limited routine community health services, including screening for non-communicable diseases (NCDs). An adaptive and innovative digital approach is needed in the health technology ecosystem. A portable health clinic (PHC) is a community-based mobile health service equipped with telemonitoring and teleconsultation using portable medical devices and an Android application. The aim of this study was to assess the challenges and potential improvement in PHC implementation in Indonesia. This study was conducted in February–April 2021 in three primary health centers, Mlati II in Sleman District, Samigaluh II in Kulon Progo, and Kalikotes in Klaten. In-depth interviews were conducted with 11 health workers and community health workers. At the baseline, 268 patients were examined, and 214 patients were successfully followed-up until the third month. A proportion of 32% of the patients required teleconsultations based on automatic triage. Implementation challenges included technical constraints such as complexity of applications; unstable networks; and non-technical constraints, such as the effectivity of training, the availability of doctors, and the workload at the primary health center. PHCs were perceived as an added value in addition to existing community-based health services. The successful implementation of PHCs should not only be considered with respect to technology but also in terms of human impact, organization, and legality.

    by Kimiyo Kikuchi, Rafiqul Islam, Yoko Sato, Mariko Nishikitani, Rieko Izukura, Nusrat Jahan, Fumihiko Yokota, Subaru Ikeda, Nazneen Sultana, Meherun Nessa, et al.

    Background: Ensuring an appropriate continuum of care in maternal, newborn, and child health, as well as providing nutrition care, is challenging in remote areas. To make care accessible for mothers and infants, we developed a telehealth care system called Portable Health Clinic for Maternal, Newborn, and Child Health. Objective: Our study will examine the telehealth care system’s effectiveness in improving women’s and infants’ care uptake and detecting their health problems. Methods: A quasi-experimental study will be conducted in rural Bangladesh. Villages will be allocated to the intervention and control areas. Pregnant women (≥16 gestational weeks) will participate together with their infants and will be followed up 1 year after delivery or birth. The intervention will include regular health checkups via the Portable Health Clinic telehealth care system, which is equipped with a series of sensors and an information system that can triage participants’ health levels based on the results of their checkups. Women and infants will receive care 4 times during the antenatal period, thrice during the postnatal period, and twice during the motherhood and childhood periods. The outcomes will be participants’ health checkup coverage, gestational and neonatal complication rates, complementary feeding rates, and health-seeking behaviors. We will use a multilevel logistic regression and a generalized estimating equation to evaluate the intervention’s effectiveness. Results: Recruitment began in June 2020. As of June 2022, we have consented 295 mothers in the study. Data collection is expected to conclude in June 2024. Conclusions: Our new trial will show the effectiveness and extent of using a telehealth care system to ensure an appropriate continuum of care in maternal, newborn, and child health (from the antenatal period to the motherhood and childhood periods) and improve women’s and infants’ health status.
