The notion of ‘mental health literacy’ has been proposed as a way of improving mental health problem recognition, service utilisation and reducing stigma. Yet the idea embodies a number of medical-model assumptions which are often at odds with diverse communities’ spiritual traditions and local belief systems. Twenty participants were recruited to this study consisting of mental health service users (N = 7), family carers (N = 8) and community members (N = 5) in a temple town in Kerala, South India participated in semi structured interviews exploring the variety of beliefs and practices relating to mental health. Our findings indicate that the issue may be better understood in terms of multiple mental health literacies which people deploy in different circumstances. Even those sceptical of traditional and spiritual approaches are knowledgeable about them, and the traditional practices themselves often involve detailed regimes of activities aimed at effecting an improvement in the person’s mood or condition. Therefore, we argue it is appropriate to consider mental health literacy not as a unitary universal phenomenon but instead as a mosaic of different literacies which may be deployed in different settings and in line with different experiences and which may operate in synergy with each other to enable treatment but also facilitate a sense of meaning and purpose in life.

Background Perinatal depression (PD) affects 10-20% of childbearing women. Telehealth is increasingly utilized for mental health services to increase access to care and overcome COVID-19 pandemic barriers. Women’s perspectives on telehealth services for PD is unknown, however. This study's primary objective was to obtain the perspectives of women who participated in an 8-week group videoconference intervention for PD symptoms, including how technology impacted their experience. Methods We utilized theoretical sampling and included perinatal women who had completed the 8-week mindfulness-based cognitive-behavioral intervention group. Semi-structured focus groups with four to six women were conducted on a videoconference platform. Primary analysis used grounded theory and a secondary analysis used qualitative description and was conducted by two coding teams. The teams collaborated on the final themes across the analyses. Results Three groups, with a total of 17 participants were conducted. Composition consisted of seven postpartum and ten pregnant women from the 47 total participants. Identified core themes regarding their experiences of the videoconference intervention were: positive experiences, negative experiences, suggestions and ideas, and screening and communication. Conclusion This study provides growing evidence informed by perinatal women of positive experiences with engagement in a videoconference intervention for PD. Telehealth may be a reasonable and acceptable platform to increase access and retention for mental health services in childbearing women. Further, this pilot work showcases videoconferencing delivery for a wide range of effective and affordable mental health services in low-resource communities.

Background: The concept of stigma has been widely used to understand patterns of discrimination and negative ideas surrounding people with mental health problems, yet we know little of the specific nuances of how this might operate beyond the ‘Global North’. Aim: This paper aims to explore the notion of stigma in an Indian context by considering the lived experience of patients, carers and community members. Methods: A sample of 204 participants, representing mental health patients, informal carers and community members was recruited from urban and rural areas in Kerala, India. Participants took part in interviews where they were encouraged to talk about their experiences of mental ill health, attitudes towards these problems, barriers encountered and sources of support. Results: Experiences akin to the experience of stigma in Europe and the United States were elicited but there were important local dimensions specific to the Indian context. The difficulties faced by people with diagnoses of mental disorders in finding marriage partners was seen as an important problem, leading to marriage proposals being refused in some cases, and secrecy on the part of those with mental health problems. Rather than the ‘self-stigma’ identified in the US, participants were more likely to see this as a collective problem in that it could reflect badly on the family group as a whole rather than just the sufferer. Conclusions: In the Indian context, the idioms of stigma emphasised impairments in marriage eligibility and the implications for the family group rather than just the self.

Background: Palliative care has an important role to play in the global coronavirus disease 2019 (COVID-19) pandemic. It is integrated and is a key component in the governmental and community structures and services in Kerala, in India. Palliative care in the state has grown to be a viable model recognized in global palliative care and public health scene. The community network of palliative care, especially the volunteers linking with clinical teams, is a strong force for advocacy, relief support including provision of emergency medications, and clinical care. Objective: To develop a palliative care resource tool kit for holistic care of patients affected with COVID-19 and to support the health-care workers looking after them to enable palliative care integration with COVID-I9 management. Methods: The Kerala State government included senior palliative care advisors in the COVID-19 task force and 22 palliative care professionals formed a virtual task force named Palli COVID Kerala as an immediate response to develop recommendations. Results: Developed a palliative care in COVID-19 resource toolkit which includes an e-book with palliative care recommendations, online training opportunities, short webinars and voice over power point presentations. Conclusion: Integrated Palliative care should be an essential part of any response to a humanitarian crisis. The e resource tool kit can be adapted for use in other low- and middle-income countries.

Gender is related not only to biological differences but also to how we are perceived and expected to think and act as women and men because of the way society is organized. Gender is one of the most important biological and social determinant that influences mental health in all its domains, epidemiology, understanding the nature and course of illness, experiences of illness and suffering, access to care treatment resources and living with and after illness in the community. The implication of understanding the link between gender and mental health paves way for improving, improvising and bringing out innovative options in all aspects of mental health care. The provision of care in the community cannot be exclusive of such factors, limiting only to the medical and traditional care-cure model. Mehac Foundation not for profit organization working in and with the community in Kerala, India, outlines its experiences with mental health and illness, indicating some important developments and components of the model, with a special focus on gender.

In a resource-poor country like India, where the health-care systems are difficult to access, overburdened, and unaffordable to many, the impact of the coronavirus disease 2019 (COVID-19) pandemic can be devastating. The increased burden of serious health-related suffering can impact the well-being of health-care workers, patients, and their families alike. The elderly, the frail, the vulnerable, and those with multiple comorbidities are disproportionately affected. Palliative care, with its comprehensive and inclusive approach, has much to offer in terms of alleviating the suffering, particularly those caused by the distressing physical and psycho-socio-spiritual symptoms, the complex medical decision-making, end-of-life care issues, and grief and bereavement, and needs to be integrated into the pathway of care provision in COVID-19. Psychosocial issues contribute to and amplify suffering and are often underestimated and undertreated and not accessible to many. Empowering frontline professionals in the core concepts of psychosocial support and palliative care thus becomes an absolute necessity. This quick review was done by a group of palliative care physicians and mental health experts from India to develop recommendations for physical and psychosocial care in the context of COVID-19. This review was done as part of that process and highlights the role and challenges of the psychosocial domain of palliative care in the context of COVID-19 situation in India.

Background: Vitamin D deficiency (low plasma 25-hydroxyvitamin D [25D] concentration) is often reported in tuberculosis. Adjunctive vitamin D has been tested for its potential to improve treatment outcomes, but has proven largely ineffective. To better understand vitamin D in tuberculosis, we investigated determinants of 25D and its immunologically active form, 1,25-dihydroxyvitamin D (1,25D), their inter-relationship in tuberculosis, longitudinal changes and association with outcome. Methods: In a prospective observational study of adults with smear-positive pulmonary tuberculosis in Sabah, Malaysia, we measured serial 25D, 1,25D, vitamin D-binding protein (VDBP), albumin, calcium, parathyroid hormone, chest x-ray, week 8 sputum smear/culture and end-of-treatment outcome. Healthy control subjects were enrolled for comparison. Results: 1,25D was elevated in 172 adults with tuberculosis (mean 229.0 pmol/L, 95% confidence interval: 215.4 - 242.6) compared with 95 controls (153.9, 138.4-169.4, p < 0.001), directly proportional to radiological severity (p < 0.001), and fell rapidly within one week of treatment commencement. Tuberculosis patients with higher baseline 1,25D achieved significantly higher percentage weight gain over time, including when controlling for baseline weight, however persistently elevated 1,25D was associated with worse residual x-ray changes and lower end-oftreatment BMI. 1,25D was inversely associated with PTH (p < 0.001), consistent with the extra-renal origin of the 1,25D. 25D did not differ between tuberculosis patients (mean 63.9 nmol/L, 95% CI: 60.6 - 67.3) and controls (61.3, 57.2- 65.3, p = 0.24), and was unassociated with outcomes. Among tuberculosis patients in multivariable analyses, sex, age and VDBP were associated with 25D, and age and albumin with 1,25D. 1,25-dihydroxyvitamin was not significantly asscociated with 25D.

BACKGROUND: Transfusion-transmitted malaria (TTM) is a well-recognized risk of receiving blood transfusions, and has occurred with Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, and Plasmodium malariae. The simian parasite Plasmodium knowlesi is also known to be transmissible through inoculation of infected blood, and this species is now the most common cause of malaria in Malaysia with a high rate of severity and fatal cases reported. No confirmed case of accidental transfusion-transmitted P. knowlesi has yet been reported. CASE PRESENTATION: A 23-year old splenectomized patient with beta thalassaemia major presented with fever 11 days after receiving a blood transfusion from a pre-symptomatic donor who presented with knowlesi malaria 12 days following blood donation. The infection resulted in severe disease in the recipient, with a parasite count of 84,000/µL and associated metabolic acidosis and multi-organ failure. She was treated with intravenous artesunate and made a good recovery. Sequencing of a highly diverse 649-base pair fragment of the P. knowlesi bifunctional dihydrofolate reductase-thymidylate synthase gene (pkdhfr) revealed that the recipient and donor shared the same haplotype. CONCLUSIONS: This case demonstrates that acquisition of P. knowlesi from blood transfusion can occur, and that clinical consequences can be severe. Furthermore, this case raises the possibility that thalassaemic patients, particularly those who are splenectomized, may represent a high-risk group for TTM and severe malaria. With rising P. knowlesi incidence, further studies in Sabah are required to determine the risk of TTM in order to guide screening strategies for blood transfusion services. Published version

Objective: To describe the impact of pandemic (H1N1) 2009 influenza (nH1N1) on Indigenous people in the Top End of the Northern Territory at community, hospital and intensive care unit (ICU) levels. Design, setting and participants: We analysed influenza notifications for the Top End from 1 June to 31 August 2009, as well as data on patients admitted through Top End emergency departments with an influenza-like illness. In addition, data on patients with nH1N1 who were admitted to Royal Darwin Hospital (RDH) and the RDH ICU were prospectively collected and analysed. Main outcome measures: Age-adjusted notification rates for nH1N1 cases, Top End hospital admission rates for patients with nH1N1 and RDH ICU admission rates for patients with nH1N1, stratified by Indigenous status. Results: There were 918 nH1N1 notifications during the study period. The age-adjusted hospital admission rate for nH1N1 was 82 per 100 000 (95% CI, 68–95) estimated resident population (ERP) overall, with a markedly higher rate in the Indigenous population compared with the non-Indigenous population (269 per 100 000 versus 29 per 100 000 ERP; adjusted incidence rate ratio, 12 [95% CI, 7.8–18]). Independent predictors of ICU admission compared with hospitalisation were hypoxia (adjusted odds ratio [aOR], 4.5; CI, 1.5–13.1) and chest x-ray infiltrates (aOR, 4.3; CI, 1.5–12.6) on hospital admission. Conclusions: Pandemic (H1N1) 2009 influenza had a disproportionate impact on Indigenous Australians in the Top End, with hospitalisation rates higher than those reported elsewhere in Australia and overseas. These findings have implications for planning hospital and ICU capacity during an influenza pandemic in regions with large Indigenous populations. They also confirm the need to improve health and living

Introduction. The burden of tuberculosis is high in eastern Malaysia, and rates of Mycobacterium tuberculosis drug resistance are poorly defined. Our objectives were to determine M. tuberculosis susceptibility and document management after receipt of susceptibility results. Methods. Prospective study of adult outpatients with smear-positive pulmonary tuberculosis (PTB) in Sabah, Malaysia. Additionally, hospital clinicians accessed the reference laboratory for clinical purposes during the study. Results. 176 outpatients were enrolled; 173 provided sputum samples. Mycobacterial culture yielded M. tuberculosis in 159 (91.9%) and nontuberculous Mycobacterium (NTM) in three (1.7%). Among outpatients there were no instances of multidrug resistant M. tuberculosis (MDR-TB). Seven people (4.5%) had isoniazid resistance (INH-R); all were switched to an appropriate second-line regimen for varying durations (4.5–9 months). Median delay to commencement of the second-line regimen was 13 weeks. Among 15 inpatients with suspected TB, 2 had multidrug resistant TB (one extensively drug resistant), 2 had INH-R, and 4 had NTM. Conclusions. Current community rates of MDR-TB in Sabah are low. However, INH-resistance poses challenges, and NTM is an important differential diagnosis in this setting, where smear microscopy is the usual diagnostic modality. To address INH-R management issues in our setting, we propose an algorithm for the treatment of isoniazid-resistant PTB.

Plasmodium vivax can cause severe malaria, however its pathogenesis is poorly understood. In contrast to P. falciparum, circulating vivax parasitemia is low, with minimal apparent sequestration in endothelium-lined microvasculature, and pathogenesis thought unrelated to parasite biomass. However, the relationships between vivax disease-severity and total parasite biomass, endothelial autocrine activation and microvascular dysfunction are unknown. We measured circulating parasitemia and markers of total parasite biomass (plasma parasite lactate dehydrogenase [pLDH] and PvLDH) in adults with severe (n = 9) and non-severe (n = 53) vivax malaria, and examined relationships with disease-severity, endothelial activation, and microvascular function. Healthy controls and adults with non-severe and severe falciparum malaria were enrolled for comparison. Median peripheral parasitemia, PvLDH and pLDH were 2.4-fold, 3.7-fold and 6.9-fold higher in severe compared to non-severe vivax malaria (p = 0.02, p = 0.02 and p = 0.015, respectively), suggesting that, as in falciparum malaria, peripheral P. vivax parasitemia underestimates total parasite biomass, particularly in severe disease. P. vivax schizonts were under-represented in peripheral blood. Severe vivax malaria was associated with increased angiopoietin-2 and impaired microvascular reactivity. Peripheral vivax parasitemia correlated with endothelial activation (angiopoietin-2, von-Willebrand-Factor [VWF], E-selectin), whereas markers of total vivax biomass correlated only with systemic inflammation (IL-6, IL-10). Activity of the VWF-cleaving-protease, ADAMTS13, was deficient in proportion to endothelial activation, IL-6, thrombocytopenia and vivax disease-severity, and associated with impaired microvascular reactivity in severe disease. Impaired microvascular reactivity correlated with lactate in severe vivax malaria. Findings suggest that tissue accumulation of P. vivax may occur, with the hidden biomass greatest in severe disease and capable of mediating systemic inflammatory pathology. The lack of association between total parasite biomass and endothelial activation is consistent with accumulation in parts of the circulation devoid of endothelium. Endothelial activation, associated with circulating parasites, and systemic inflammation may contribute to pathology in vivax malaria, with microvascular dysfunction likely contributing to impaired tissue perfusion.

Background Tuberculosis (TB) is generally well controlled in Malaysia, but remains an important problem in the nation’s eastern states. In order to better understand factors contributing to high TB rates in the eastern state of Sabah, our aims were to describe characteristics of patients with TB at a large outpatient clinic, and determine the prevalence of HIV co-infection. Additionally, we sought to test sensitivity and specificity of the locally-available point-of-care HIV test kits. Methods We enrolled consenting adults with smear-positive pulmonary TB for a 2-year period at Luyang Clinic, Kota Kinabalu, Malaysia. Participants were questioned about ethnicity, smoking, prior TB, disease duration, symptoms and comorbidities. Chest radiographs were scored using a previously devised tool. HIV was tested after counselling using 2 point-of-care tests for each patient: the test routinely in use at the TB clinic (either Advanced Quality™ Rapid Anti-HIV 1&2, FACTS anti-HIV 1/2 RAPID or HIV (1 + 2) Antibody Colloidal Gold), and a comparator test (Abbott Determine™ HIV-1/2, Inverness Medical). Positive tests were confirmed by enzyme immunoassay (EIA), particle agglutination and line immunoassay. Results 176 participants were enrolled; 59 (33.5%) were non-Malaysians and 104 (59.1%) were male. Smoking rates were high (81/104 males, 77.9%), most had cavitary disease (51/145, 64.8%), and 81/176 (46.0%) had haemoptysis. The median period of symptoms prior to treatment onset was 8 weeks. Diabetes was present in 12. People with diabetes or other comorbidities had less severe TB, suggesting different healthcare seeking behaviours in this group. All participants consented to HIV testing: three (1.7%) were positive according to Determine™ and EIA, but one of these tested negative on the point-of-care test available at the clinic (Advanced Quality™ Rapid Anti-HIV 1&2). The low number of positive tests and changes in locally-available test type meant that accurate estimates of sensitivity and specificity were not possible. Conclusion Patients had advanced disease at diagnosis, long diagnostic delays, low HIV co-infection rates, high smoking rates among males, and migrants may be over-represented. These findings provide important insights to guide local TB control efforts. Caution is required in using some point-of-care HIV tests, and ongoing quality control measures are of major importance.

Plasmodium knowlesi causes severe and fatal malaria in Malaysia. Microscopic misdiagnosis is common and may delay appropriate treatment. P. knowlesi can cross-react with “species-specific” parasite lactate dehydrogenase (pLDH) monoclonal antibodies used in rapid diagnostic tests (RDTs) to detect P. falciparum and P. vivax . At one tertiary-care hospital and two district hospitals in Sabah, we prospectively evaluated two combination RDTs for malaria diagnosis by using both a pan- Plasmodium -pLDH (pan-pLDH)/ P. falciparum -specific-pLDH ( Pf -pLDH) RDT (OptiMAL-IT) and a non- P. falciparum VOM-pLDH/ Pf -HRP2 RDT (CareStart). Differential cross-reactivity among these combinations was hypothesized to differentiate P. knowlesi from other Plasmodium monoinfections. Among 323 patients with PCR-confirmed P. knowlesi ( n = 193), P. falciparum ( n = 93), and P. vivax ( n = 37) monoinfections, the VOM-pLDH individual component had the highest sensitivity for nonsevere (35%; 95% confidence interval [CI], 27 to 43%) and severe (92%; CI, 81 to 100%) P. knowlesi malaria. CareStart demonstrated a P. knowlesi sensitivity of 42% (CI, 34 to 49%) and specificity of 74% (CI, 65 to 82%), a P. vivax sensitivity of 83% (CI, 66 to 93%) and specificity of 71% (CI, 65 to 76%), and a P. falciparum sensitivity of 97% (CI, 90 to 99%) and specificity of 99% (CI, 97 to 100%). OptiMAL-IT demonstrated a P. knowlesi sensitivity of 32% (CI, 25 to 39%) and specificity of 21% (CI, 15 to 29%), a P. vivax sensitivity of 60% (CI, 42 to 75%) and specificity of 97% (CI, 94 to 99%), and a P. falciparum sensitivity of 82% (CI, 72 to 89%) and specificity of 39% (CI, 33 to 46%). The combination of CareStart plus OptiMAL-IT for P. knowlesi using predefined criteria gave a sensitivity of 25% (CI, 19 to 32%) and specificity of 97% (CI, 92 to 99%). Combining two RDT combinations was highly specific for P. knowlesi malaria diagnosis; however, sensitivity was poor. The specificity of pLDH RDTs was decreased for P. vivax and P. falciparum because of P. knowlesi cross-reactivity and cautions against their use alone in areas where P. knowlesi malaria is endemic. Sensitive P. knowlesi -specific RDTs and/or alternative molecular diagnostic tools are needed in areas where P. knowlesi malaria is endemic.

Objective: To compare the unprecedented 91 cases of melioidosis in the Top End of the Northern Territory of Australia from 1 October 2009 to 30 September 2010 with the 540 cases in the preceding 20 years and postulate reasons for this year of very high melioidosis incidence. Design, setting and participants: Review of prospectively collected data on all patients with culture-confirmed melioidosis at Royal Darwin Hospital, the Top End’s tertiary referral centre, since 1 October 1989. Main outcome measures: Population-based annual incidence of melioidosis; differences in epidemiology, clinical presentations and outcomes for 2009–2010 compared with the preceding 20 years. Results: In 2009–2010, the estimated population-based incidence of melioidosis was 50.2 cases per 100 000 in the Top End population overall, and 102.4 cases per 100 000 in the Top End Indigenous population. The proportion of patients acquiring melioidosis in the Darwin urban area increased from 49% in 1989–2009 to 65% in 2009–2010 (OR, 1.96; 95% CI, 1.20–3.19). Among the 49 Indigenous Australian patients with melioidosis in 2009–2010, 63% acquired the infection in Darwin, compared with 35% of Indigenous patients in the previous 20 years (OR, 3.17; 95% CI, 1.62–6.24). Conclusions: In 2009–2010, the Top End had the highest annual incidence of melioidosis documented from anywhere to date. The prominent increase in cases in Darwin was associated with above average rainfall in Darwin during December 2009 to February 2010. The increase in the proportion of Indigenous Australians who acquired melioidosis in Darwin may reflect movement of some Indigenous people into Darwin from remote communities.

The commercially available catalytic processes for NOx abatement involve the use of transition metal ions such as V 4+/5+ , W 6+ , Cu 2+ etc. on a titania (anatase) or zeolite support. The metal ions catalyse the reaction between nitric oxide, ammonia and oxygen to give nitrogen and water. Using Indian ilmenite, high surface area titania (anatase) has been obtained which when doped with optimum amounts of transition metal ions, yields a catalyst capable of converting NOx with more than 90% efficiency within a temperature window of 250–450°C. Moreover this catalyst has minimal SO 2 oxidation activity even at high temperatures (450 °C). This catalyst therefore has the potential of commercial use in coal fired thermal power plants where the NOx has a high level of SO 2 impurity. Accelerated ageing tests have also been carried out on this catalyst and these studies indicate that the expected lifetime would be greater than or equal to five years. Spectroscopic and other physico-chemical data on the fresh and used catalysts are also presented.
