Accurate estimation of perinatal sleep is important for informing future research and multigenerational health interventions. We compared diary- and actigraphy-estimated sleep parameters during pregnancy and postpartum. We informed our interpretation of these analyses with participants' feedback about these sleep estimation methods.

Perinatal depression affects 5-15% of childbearing women. However, literature suggests that Latina women are twice as likely to experience depression during pregnancy. Group telehealth-based interventions are a promising approach to increasing access and reducing barriers to mental health.

Separate literatures have demonstrated that mothers' experiences with trauma during childhood or pregnancy are associated with maternal prenatal health risks, adverse childbirth outcomes, and offspring internalizing and externalizing disorders. These literatures largely align with the intergenerational transmission or fetal programming frameworks, respectively. However, few studies have tested the effects of maternal childhood and prenatal trauma simultaneously on mothers' and infants' health outcomes, and no studies have examined these effects on newborn neurobehavioral outcomes.

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.

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.

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.

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.

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.

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.

Background.  Endothelial nitric oxide (NO) bioavailability is impaired in severe falciparum malaria (SM). Asymmetric dimethylarginine (ADMA), an endogenous inhibitor of NO synthase (NOS), contributes to endothelial dysfunction and is associated with mortality in adults with falciparum malaria.

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.

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.

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.

Article Synopsis
  • The study focused on the effects of the H1N1 pandemic on Indigenous people in Northern Territory, analyzing community, hospital, and ICU levels from June to August 2009.
  • There were 918 reported cases, with Indigenous individuals significantly more likely to be hospitalized for H1N1 compared to non-Indigenous individuals (269 vs. 29 per 100,000).
  • The findings suggest that greater resources and better health conditions are needed for Indigenous populations during pandemics, highlighting the importance of vaccination and healthcare planning.
