Modulating the hAM/PCL Biocomposite for Expedited Wound Healing: A Chemical-Free Approach for Boosting Regenerative Potential.

There is an arising need for effective wound dressings that retain the bioactivity of a cellular treatment, but without the high costs and complexities associated with manufacturing, storing, and applying cell-based products. As skin wound recovery is a dynamic and complicated process, a significant obstacle to the healing of skin wounds is the lack of an appropriate wound dressing that can imitate the microenvironment of healthy skin and prevent bacterial infection. It requires the well-orchestrated integration of biological and molecular events. In this study, we have fabricated full-thickness skin graft biocomposite membranes to target full-thickness skin excision wounds. We reinforced human amniotic membrane (hAM) with electrospun polycaprolactone (PCL) to develop composite membranes, namely, PCL/hAM and PCL/hAM/PCL. Composite membranes were compared for physical, biological, and mechanical properties with the native counterpart. PCL/hAM and PCL/hAM/PCL displayed improved stability and delayed degradation, which further synergically improved the rapid wound healing property of hAM, driven primarily by wound closure analysis and histological assessment. Moreover, PCL/hAM displayed a comparable cellular interaction to hAM. On application as a wound dressing, histological analysis demonstrated that hAM and PCL/hAM promoted early epidermis and dermis formation. Studies on in vivo wound healing revealed that although hAM accelerates cell development, the overall wound healing process is similar in PCL/hAM. This finding is further supported by the immunohistochemical analysis of COL-1/COL-3, CD-31, and TGF-ß. Overall, this conjugated PCL and hAM-based membrane has considerable potential to be applied in skin wound healing. The facile fabrication of the PCL/hAM composite membrane provided the self-regenerating wound dressing with the desired mechanical strength as an ideal regenerative property for skin tissue regeneration.

Outcome of obstructed total anamalous pulmonary venous connection (TAPVC) repair patients with milrinone versus milrinone and inhaled nitric oxide (INO): A prospective randomized observational study.

Background: Obstructed total anomalous pulmonary venous connection (TAPVC) typically present with severe cardiovascular decompensation and requires urgent surgical management. Pulmonary arterial hypertension (PAH) is a major risk factor affecting mortality. Perioperative management focuses on providing inotropic support and managing potential pulmonary hypertensive episodes. Milrinone and inhaled nitric oxide (iNO) efficiently reduce pulmonary artery pressure (PAP) and help to improve the outcome. The aim was to determine the outcome of patients with high PAP with milrinone alone and a combination of iNO and milrinone. Material and Method: After ethical committee approval, the study was conducted over a period of 3 years in 80 patients with obstructed TAPVC repair. A total of 80 patients having severe PAH (supra systemic arterial pressure) randomly divided into two groups with 40 patients in each (M & MN). Group M (milrinone) patients received milrinone and Group MN (milrinone & iNO) patients received both milrinone (after opening aortic cross clamp) and iNO (post operative ICU). Ventilation time, hospital stay, ICU stay, complications, in hospital mortality were compared between both groups. Result: Ventilation time, Intensive Care Unit (ICU) stay, hospital stay for group M was 8.02 ± 5.74 days, 11.25 ± 7.33 day, 14.92 ± 8.55 days, respectively, and for group MN was 5.02 ± 1.78 days, 8.27 ± 3.24 days, 10.3 ± 3.18 days, respectively. In hospital mortality for group M and MN was 10% and 2.5%, respectively. P value for each variable was significant < 0.05 (except mortality). Conclusion: Most of the patients with obstructed TAPVC had severe PAH. Management of severe PAH with a combination of milrinone with iNO had a better outcome than milrinone alone.

SMARThealth PRegnancy And Mental Health study: protocol for a situational analysis of perinatal mental health in women living in rural India.

Introduction: The situation for women experiencing mental health problems during pregnancy and postpartum in rural India is critical: a high burden of disease, a high estimated number of women are undiagnosed and untreated with mental health problems, a substantial gap in research on women's perinatal health, and severe stigma and discrimination. The SMARThealth Pregnancy study is a cluster randomised trial using a digital intervention to identify and manage anaemia, hypertension, and diabetes in the first year after birth in rural India. Within this study, the SMARThealth Pregnancy and Mental Health (PRAMH) study is a situational analysis to understand mental health problems during pregnancy and in the first year following birth in this population. Methods/design: This situational analysis aims to analyse and to assess the context of perinatal mental health, health services, barriers, facilitators, and gaps in Siddipet district of Telangana state in India, to develop an implementation framework for a future intervention. A tested, standardised situational analysis tool will be adapted and applied to perinatal mental health in rural India. A desktop and policy review will be conducted to identify and analyse relevant mental health and pregnancy care policies at the national and state levels. We will conduct in-depth interviews with policymakers, planners, mental health professionals and other experts in perinatal mental health (n = 10-15). We will also conduct focus group discussions with key stakeholders, including women with perinatal mental health problems, their families and carers, and community health workers (n = 24-40). A theory of change workshop with key stakeholders will be conducted which will also serve as a priority setting exercise, and will clarify challenges and opportunities, priorities, and objectives for a pilot intervention study. The analysis of qualitive data will be done using thematic analysis. Based on the data analysis and synthesis of the findings, an implementation framework will be developed to guide development, testing and scale up of a contextually relevant intervention for perinatal mental health. Discussion: The situational analysis will help to establish relationships with all relevant stakeholders, clarify the context and hypotheses for the pilot intervention and implementation.

A community-based intervention to improve screening, referral and follow-up of non-communicable diseases and anaemia amongst pregnant and postpartum women in rural India: study protocol for a cluster randomised trial.

BACKGROUND: Medical complications during pregnancy, including anaemia, gestational diabetes mellitus and hypertensive disorders of pregnancy place women are at higher risk of long-term complications. Scalable and low-cost strategies to integrate non-communicable disease screening into pregnancy care are needed. We aim to determine the effectiveness and implementation components of a community-based, digitally enabled approach, "SMARThealth Pregnancy," to improve health during pregnancy and the first year after birth. METHODS: A pragmatic, parallel-group, cluster randomised, type 2 hybrid effectiveness-implementation trial of a community-based, complex intervention in rural India to decrease anaemia (primary outcome, defined as haemoglobin < 12g/dL) and increase testing for haemoglobin, glucose and blood pressure (secondary outcomes) in the first year after birth. Primary Health Centres (PHCs) are the unit of randomisation. PHCs are eligible with (1) > 1 medical officer and > 2 community health workers; and (2) capability to administer intravenous iron sucrose. Thirty PHCs in Telangana and Haryana will be randomised 1:1 using a matched-pair design accounting for cluster size and distance from the regional centre. The intervention comprises (i) an education programme for community health workers and PHC doctors; (ii) the SMARThealth Pregnancy app for health workers to support community-based screening, referral and follow-up of high-risk cases; (iii) a dashboard for PHC doctors to monitor high-risk women in the community; (iv) supply chain monitoring for consumables and medications and (v) stakeholder engagement to co-develop implementation and sustainability pathways. The comparator is usual care with additional health worker education. Secondary outcomes include implementation outcomes assessed by the RE-AIM framework (reach, effectiveness, adoption, implementation, maintenance), clinical endpoints (anaemia, diabetes, hypertension), clinical service delivery indicators (quality of care score), mental health and lactation practice (PHQ9, GAD7, EuroQoL-5D, WHO IYCF questionnaire). DISCUSSION: Engaging women with screening after a high-risk pregnancy is a challenge and has been highlighted as a missed opportunity for the prevention of non-communicable diseases. The SMARThealth Pregnancy trial is powered for the primary outcome and will address gaps in the evidence around how pregnancy can be used as an opportunity to improve women's lifelong health. If successful, this approach could improve the health of women living in resource-limited settings around the world. TRIAL REGISTRATION: ClinicalTrials.gov NCT05752955.

A Mobile Clinical Decision Support System for High-Risk Pregnant Women in Rural India (SMARThealth Pregnancy): Pilot Cluster Randomized Controlled Trial.

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of death in women in India. Early identification is crucial to reducing deaths. Hypertensive disorders of pregnancy (HDP) and gestational diabetes mellitus (GDM) carry independent risks for future CVD, and antenatal care is a window to screen and counsel high-risk women. In rural India, community health workers (CHWs) deliver antenatal and postnatal care. We developed a complex intervention (SMARThealth Pregnancy) involving mobile clinical decision support for CHWs and evaluated it in a pilot cluster randomized controlled trial (cRCT). OBJECTIVE: The aim of the study is to co-design a theory-informed intervention for CHWs to screen, refer, and counsel pregnant women at high risk of future CVD in rural India and evaluate its feasibility and acceptability. METHODS: In phase 1, we used qualitative methods to explore community priorities for high-risk pregnant women in rural areas of 2 diverse states in India. In phase 2, informed by behavior change theory and human-centered design, we used these qualitative data to develop the intervention components and implementation strategies for SMARThealth Pregnancy in an iterative process with end users. In phase 3, using mixed methods, we evaluated the intervention in a cRCT with an embedded qualitative substudy across 4 primary health centres: 2 in Jhajjar district, Haryana, and 2 in Guntur district, Andhra Pradesh. RESULTS: SMARThealth Pregnancy embedded a total of 15 behavior change techniques and included (1) community awareness programs; (2) targeted training, including point-of-care blood pressure and hemoglobin measurement; and (3) mobile clinical decision support for CHWs to screen women in their homes. The intervention focused on 3 priority conditions: anemia, HDP, and GDM. The evaluation involved a total of 200 pregnant women, equally randomized to intervention or enhanced standard care (control). Recruitment was completed within 5 months, with minimal loss to follow-up (4/200, 2%) at 6 weeks postpartum. A total of 4 primary care doctors and 54 CHWs in the intervention clusters took part in the study. Fidelity to intervention practices was 100% prepandemic. Over half the study population was affected by moderate to severe anemia at baseline. The prevalence of HDP (2.5%) and GDM (2%) was low in our study population. Results suggest a possible improvement in mean hemoglobin (anemia) in the intervention group, although an adequately powered trial is needed. The model of home-based care was feasible and acceptable for pregnant or postpartum women and CHWs, who perceived improvements in quality of care, self-efficacy, and professional recognition. CONCLUSIONS: SMARThealth Pregnancy is an innovative model of home-based care for high-risk pregnant women during the transitions between antenatal and postnatal care and adult health services. The use of theory and co-design during intervention development facilitated acceptability of the intervention and implementation strategies. Our experience has informed the decision to initiate a larger-scale cRCT. TRIAL REGISTRATION: ClinicalTrials.gov NCT03968952; https://clinicaltrials.gov/ct2/show/NCT03968952.

No going back: COVID-19 disease threat perception and male migrants' willingness to return to work in India.

This paper explores the causal link between the likelihood of re-migration to cities and the perceived threat of contracting COVID-19 using novel data on male reverse migrant workers in India. We find that reverse-migrants who believe there is a significant chance of contracting COVID-19 display a significantly lower likelihood of returning to their urban workplaces, regardless of their duration of migration. On the other hand, longer-duration migrants display a lower perceived chance of contracting COVID-19 than shorter-duration migrants. We also contribute to the migration literature by linking behavioural attributes to the decision to migrate. We find that more impatient individuals display a heightened belief regarding contracting COVID-19 and a higher projected likelihood of returning to work. Finally, we find that while both loss and risk-averse individuals have a lower projected likelihood of returning to urban workplaces, only loss-averse individuals perceive that their chance of contracting COVID-19 is lower.

Biocompatible dressing for pediatric hypospadias repair.

PURPOSE: The search for an ideal Hypospadias repair dressing continues. We aimed to develop a hypoallergenic optimized biocompatible dressing (BD). METHOD: BD with a multi-layered structure of hydrophilic treated Polypropylene with three-layered technologies; Absorbent-spunlaced hydroentangled polyester/viscose blend, outer Polypropylene, Polyester, Acrylic, and Spandex, with super Absorbent Polymer and Acrylic adhesive. Wistar rat abdominal wound model was divided into two groups: control (normal gauze dressing with adhesive) and Study (BD). The physical properties and wound characteristics were compared. RESULTS: Average mass: thickness of BD was 626.7 ± 5.6 g m-2: 2.6 ± 0.015 mm. Absorption was 1425.2 ± 127.6%. Percentage desorption of solution A from dressings at 24:40 h was 1249 ± 150%:1417 ± 230%. BD was hydrophilic with no particles/residue after immersion and pH neutral. The average air permeability was 11.6 ± 1.6 cm3/cm2/sec. The tensile force was 200N-220N with an extension on the breaking point at 24 mm. BD was superior for ease of removability on Day 6 (p = 0.012) and sticking quality (p = 0.036), absorption (p = 0.036), ease of removability(p = 0.036), and sustenance (p = 0.030) on Day 10. BD dressing demonstrated better wound healing (p = 0.015) and decreased redness (p = 0.002) on Day 10. Histopathological healing was better with BD on Day 14(p = 0.025) and Day 20 (p = 0.034). CONCLUSION: BD demonstrated better desirable physical and wound healing qualities with less inflammation compared with control normal dressing.

Double Jab: Survey Evidence on Vaccine Hesitancy, Beliefs, and Attitudes in India.

India witnessed a large surge in COVID-19 cases in April 2021, a second wave of nearly 350,000 daily new infections across the country. As of December 2021, cases have reduced drastically, in part due to greater vaccine coverage across the country. This study reports results on vaccine hesitancy, attitudes, and behaviors from an online survey conducted between February and March 2021 in nine Indian cities (N = 518). We find that vaccine hesitancy negatively predicts willingness to take the vaccine, and beliefs about vaccine effectiveness supersede hesitancy in explaining vaccine uptake. Furthermore, we find that mask-wearing and handwashing beliefs, information sources related to COVID-19, and past COVID-19 infection and testing status are all strongly associated with the hypothetical choice of vaccine. We discuss these findings in the context of behavioral theories as well as outline implications for vaccine-related health communication in India.

Analysis of Maternal and Infant Death Reporting System (MIDRS) in a North Indian State during 2013-2018.

Background: Haryana launched the Maternal and Infant Death Reporting System (MIDRS) in 2013 to report deaths and their causes. We evaluated the system in terms of its data quality, accuracy, and timing of reporting. Methods: Secondary data analysis of data about the maternal, infant, and child deaths from the state level MIDRS portal from 2013 to 2018. The portal combines infant and maternal deaths and stillbirths reported through passive and active surveillance. We used the descriptive measure of statistics (proportion) to describe the characteristics and causes of neonatal, post-neonatal, and maternal deaths. Results: Of 1,18, 028 neonatal deaths, 39% (46,140) neonates died at a government facility. Gender was not recorded in 7,093 (6.0%) deaths. "Others" was a predominant category (14,664, 53%) of death. Of 2,842 maternal deaths, the cause of death was unknown in 465 (16.4%) deaths and mentioned as "others" in 1,618 (56.9%) instances. Nearly 60% of maternal deaths occurred at a health facility. Stillbirth was published as a cause of death in 228 (7.8%) child deaths (1-5 years). Missing data were observed in critical variables such as the timing of maternal mortality (50, 1.8%) and sex of child (4884, 4.3%). Conclusion: Delay in reporting, inconsistencies in data, and missing information were some challenges. Ascertainment of the exact cause of death needs to be improved through better training.

SMARThealth Pregnancy: Feasibility and Acceptability of a Complex Intervention for High-Risk Pregnant Women in Rural India: Protocol for a Pilot Cluster Randomised Controlled Trial.

Introduction: India is in the process of a major epidemiological transition towards non-communicable diseases. Cardiovascular disease (CVD) is the leading cause of death in women in India. Predisposing independent risk factors include pregnancy-related conditions, e.g., hypertensive disorders of pregnancy (HDP) and gestational diabetes (GDM) - also associated with significant perinatal mortality and morbidity. Early identification, referral and management of pregnant women at increased risk of future CVD may offer opportunities for prevention. In rural India, Community Health Workers (CHWs) provide most antenatal and postnatal care. Innovative solutions are required to address integrated care for rural women during transitions between antenatal, postnatal and general health services. The George Institute's SMARThealth Programme has shown that CHWs in rural India screening non-pregnant adults for cardiovascular risk, using a decision support system, is feasible. Building on this, we developed a targeted training programme for CHWs and a complex system-level intervention that uses mobile clinical decision support for CHWs and primary care doctors to screen high-risk pregnant women. In addition to addressing HDP and GDM, the intervention also screens for anaemia in pregnancy. Methods/Design: A pilot study will be undertaken in two diverse rural districts of India: Jhajjar (Haryana) and Guntur (Andhra Pradesh). Two Primary Health Centre clusters will be randomised to intervention or control groups at each study site. The primary objective of this pilot study is to explore the feasibility and acceptability of the SMARThealth Pregnancy intervention. Secondary objectives are to estimate: (a) prevalence rates of moderate to severe anaemia, HDPs and GDM at the study sites; (b) referral and follow-up rates, and (c) mean haemoglobin and blood pressure values at the routine 6 week postnatal visit. A process evaluation will be conducted to explore the acceptability of the SMARThealth Pregnancy intervention for pregnant women and healthcare workers using qualitative methods. Discussion: It is anticipated that the findings of this pilot study will help determine the feasibility and acceptability of the SMARThealth Pregnancy intervention, and highlight how the intervention might be further developed for evaluation in a larger, cluster randomised controlled trial.

Endemic Syndromes associated with Diabetes - A call for Awareness, recognition and management in India and beyond.

Diabetes mellitus has reached pandemic proportions throughout the globe. Though hyperglycaemia is the hall mark feature of diabetes, there are several variations in its etiology, clinical presentation, and associated complications. Some of these variations have been distinctly described in specific regions and ethnicities across India and other regions in the world. In this commentary we describe these endemic syndromes associated with diabetes to improve their awareness, recognition and management. A focused attention on these relatively neglected clinical challenges would encourage future discussion and research to address these conditions.

Graphene nanofiber composites for enhanced neuronal differentiation of human mesenchymal stem cells.

Aim: To differentiate mesenchymal stem cells into functional dopaminergic neurons using an electrospun polycaprolactone (PCL) and graphene (G) nanocomposite. Methods: A one-step approach was used to electrospin the PCL nanocomposite, with varying G concentrations, followed by evaluating their biocompatibility and neuronal differentiation. Results: PCL with exiguous graphene demonstrated an ideal nanotopography with an unprecedented combination of guidance stimuli and substrate cues, aiding the enhanced differentiation of mesenchymal stem cells into dopaminergic neurons. These newly differentiated neurons were seen to exhibit unique neuronal arborization, enhanced intracellular Ca2+ influx and dopamine secretion. Conclusion: Having cost-effective fabrication and room-temperature storage, the PCL-G nanocomposites could pave the way for enhanced neuronal differentiation, thereby opening a new horizon for an array of applications in neural regenerative medicine.

Imaging application and radiosensitivity enhancement of pectin decorated multifunctional magnetic nanoparticles in cancer therapy.

In this contribution, we report the fabrication of multifunctional nanoparticles with gold shell over an iron oxide nanoparticles (INPs) core. The fabricated system combines the magnetic property of INPs and the surface plasmon resonance of gold. The developed nanoparticles are coated with thiolated pectin (TPGINs), which provides stability to the nanoparticles dispersion and allows the loading of hydrophobic anticancer drugs. Curcumin (Cur) is used as the model drug and an encapsulation efficiency of approximately 80% in TPGINs is observed. Cytotoxicity study with HeLa cells shows that Cur-loaded TPGINs have better viability percent (~30%) than Cur alone (~40%) at a dose of 30 µg of TPGINs. Further, annexin V-PI assay demonstrated the enhanced anticancer activity of Cur-loaded TPGINs via induction of apoptosis. The use of TPGINs leads to a significant enhancement in generating reactive oxygen species (ROS) in HeLa cells through improved radiosensitization by gamma irradiation (0.5 Gy). TPGINs are further evaluated for imparting contrast in magnetic resonance imaging (MRI) with the r2 relaxivity in the range of 11.06-13.94 s-1 µg-1 mL when measured at 7 Tesla. These experimental results indicate the potential of TPGINs for drug delivery and MR imaging.

Diabetic Foot Care Knowledge and Practices in Rural North India: Insights for Preventive Podiatry.

BACKGROUND: Diabetic foot ulcer (DFU) is one of the most dreaded complications of Type 2 Diabetes Mellitus (T2DM). Preventive podiatry is most efficient way of minimising DFU. The main aim of the study was to assess the knowledge and foot care practices among patients living with T2DM concerning the DFU. MATERIALS AND METHODS: We conducted a cross-sectional study in a rural-area of Haryana, India between January to March 2019 amongst 416 people living with T2DM after using multistage random sampling. A pre-tested, structured survey instrument prepared from the recommendation of the American College of Foot and Ankle Surgeons and the Diabetes UK was used after Hindi translation as per standard protocol. The knowledge and practices were classified as good, satisfactory and poor if the total score was between 8-11, 6-7 and <6. RESULTS: 14.2% had a previous history of DFU. The prevalence of good, satisfactory and poor knowledge was 63.5%, 12.5% and 24.0%. Further, 46.7%, 32.7% and 20.6% respondents depicted good, satisfactory and poor practices regarding foot care. On multivariate binary logistic regression analysis, younger age group, higher education, Per capita family income in INR, Blood glucose levels, HbA1c Levels, physical activity and previous history of DFU emerged as significant predictors of good foot-care knowledge and practices. CONCLUSION: There is an evident gap between foot-care knowledge and practices that should be addressed through comprehensive behaviour change strategies. Comprehensive risk-assessments for diabetes associated complications needs to be piloted at community level to assess the feasibility.

Glycaemic hygiene.

Hygiene is the foundation of health. This communication proposes the concept of glycaemic hygiene, defined as "conditions and practices that help to maintain health, and prevent the development of diabetes mellitus and its complications". Glycaemic hygiene is relevant at the level of the person, the physician and the community. Aspects such as personal hygiene, food hygiene, physical activity hygiene, mental/ emotional hygiene and dental hygiene must be optimized to ensure good health individuals. Skin hygiene, vaccine hygiene and environmental hygiene are equally important in diabetes care. Physicians should ensure pharmacological hygiene, language hygiene and information hygiene to foster good diabetes self-care and management.
