Introduction: Global evidence suggests that high out-of-pocket (OOP) expenditure negatively affects health service utilization and creates an economic burden on households during pregnancy. This study aimed to estimate the magnitude and associated factors of OOP expenditure for antenatal care (ANC) in a rural Sri Lankan setting by following up with a large pregnancy cohort (The Rajarata Pregnancy Cohort [RaPCo]) in Anuradhapura District, Sri Lanka.

Methods: Data were collected from July 2019 to May 2020.

Early identification of mental health problems in pregnancy in low-income and middle-income countries is scarcely reported. We present the experience of a programme assimilating screening and management of antenatal anxiety and depression in conjunction with the Rajarata Pregnancy Cohort, in Sri Lanka. We adopted a two-stage screening approach to identify the symptoms and the reasons for anxiety and depression.

Article Synopsis
  • Lip, oral, and pharyngeal cancers pose significant global health challenges, making it essential to analyze their burden for effective health policies.
  • The study utilized data from the 2019 Global Burden of Diseases, Injuries, and Risk Factors Study to assess cancer incidence, mortality, and life years lost across 204 countries, linking these to socio-demographic factors.
  • Findings revealed approximately 370,000 cases and 199,000 deaths for lip and oral cavity cancer, and 167,000 cases and 114,000 deaths for other pharyngeal cancers in 2019, with smoking being the leading risk factor for these cancers, especially in low and middle SDI regions.

  • Estimating health loss trends in Peru from 1990 to 2019 is crucial for improving healthcare resource allocation and system performance, using data from the Global Burden of Disease study.
  • The Peruvian population rose to 33.9 million by 2019, with life expectancy at birth increasing from 69.2 to 80.3 years, largely due to a decrease in under-5 mortality and infectious diseases, while disability-adjusted life-years (DALYs) showed a decline in overall health burden.
  • There was a notable shift towards non-communicable diseases as the leading cause of health loss, with major contributors to DALYs in 2019 including neonatal disorders, lower respiratory infections, and lifestyle

Background: Knowledge of early clinical manifestations, people's perceptions and behaviours is crucial in preventing and controlling neglected tropical diseases (NTDs). Cutaneous leishmaniasis is an NTD that causes skin lesions and affects millions worldwide. Delayed healthcare-seeking behaviour leading to prolonged treatment periods and complications is rife among people with cutaneous leishmaniasis.

Renal functions in pregnancy undergo rapid changes, and the thresholds for normal values are a major research gap and are still debatable. The lack of prospective population-based studies with early pregnancy recruitment hampered the decision-making process on the best thresholds to be used in clinical practice. We present the serum creatinine (sCr) and sCr-based estimated glomerular filtration rates (eGFR) in early pregnancy with changes over the gestational period in a large prospective, community-based cohort, the Rajarata Pregnancy Cohort (RaPCo).

Introduction: The occurrence of concurrent hypertrophied posterior longitudinal ligament (HPLL) and hypertrophied ligamentum flavum (HLF) in the thoracic spine is a very rare presentation. This case report describes a young female who developed thoracic myelopathy secondary to a combination of both thoracic HPLL and HLF.

Case Presentation: A 30-year-old previously well female was referred for an MRI scan of the thoraco-lumbar spine.

  • HIV/AIDS remains a significant public health issue in sub-Saharan Africa, with current efforts falling short of global targets for eradication set by UNAIDS and the SDGs.
  • The study utilized extensive data from various HIV prevalence surveys to estimate localized HIV infection rates across 43 African countries, focusing on specific age and sex groups from 2000 to 2018.
  • Findings revealed wide disparities in HIV prevalence within countries and districts, indicating that age and sex stratification provides more nuanced insights into the epidemic, which can help tailor prevention and treatment efforts more effectively.

Article Synopsis
  • Human intestinal nematode infections are a significant global health problem, particularly in developing countries, where they often go undiagnosed due to a lack of resources and infrastructure.
  • Diagnostic methods range from traditional microscopic techniques, which are less sensitive and more labor-intensive, to advanced molecular approaches like nucleic acid amplification tests (NAAT), which offer rapid and accurate detection.
  • The review aims to evaluate the accuracy of NAATs against established tests for detecting these infections, using specific reference methods for various types of nematodes, while ensuring thorough literature screening and quality assessment of the studies involved.

Background: Ending preventable maternal deaths remains a challenge in low- and middle-income countries (LMICs). Society perceived causes and real-life observations can reveal the intangible causes of maternal deaths irrespective of formal maternal death investigations. This study reports complex patterns in which social determinants act towards paving the path to maternal deaths in a rural Sri Lankan setting.

Background: Owing to the lack of compiled global evidence on out-of-pocket expenditure (OOPE) for antenatal care (ANC), this systematic review and meta-analysis estimated the magnitude of OOPE for ANC in low and middle-income countries (LMICs).

Methods: An electronic search was conducted using 10 databases and a hand search of the eligible studies' reference lists. Studies on OOPE for ANC in LMICs, published in English without time restriction, were included.

Purpose: Against the backdrop of the ever-increasing aging population in Sri Lanka and the scarcity of local evidence on quality of life (QoL) among rural elderly, this study was conducted to assess the QoL of the community-dwelling older adults in rural Sri Lanka.

Methods: This cross-sectional study was conducted among community-dwelling older adults (60-74 years) in a selected rural setting in Sri Lanka. K-means cluster analysis was used to stratify participants into 'low' and 'high' levels of QoL and then significant associations between these clusters and underlying socio-demographic and self-reported health related factors were estimated using bivariate and subsequent multivariable binary logistic regression models.

Investigating the out-of-pocket expenditure (OOPE) associated with maternal health is important since OOPE directly affects the affordability of health services. Global evidence suggests the importance of capturing the productivity cost during pregnancy in terms of absenteeism and presenteeism. Furthermore, the impact of the ongoing COVID-19 pandemic on the household economy needs to be further evaluated as pregnant women are one of the most vulnerable groups.

Background: Cross-sectional imaging findings of portal vein calcification were found to be an indicator of portal vein thrombosis. Calcification of the portal vein and its tributaries in portal hypertension is an uncommon finding and the mechanical stress due to long-standing portal hypertension on the vessel wall is considered leading to sclerosis and calcification in the intima and media of the vessel wall. Intra-splenic vascular calcification is a rare occurrence and has been seen in patients with portal hypertension.
