The chloroplast (cp) genome is a widely used tool for exploring plant evolutionary relationships, yet its effectiveness in fully resolving these relationships remains uncertain. Integrating cp genome data with nuclear DNA information offers a more comprehensive view but often requires separate datasets. In response, we employed the same raw read sequencing data to construct cp genome-based trees and nuclear DNA phylogenetic trees using Read2Tree, a cost-efficient method for extracting conserved nuclear gene sequences from raw read data, focusing on the Aurantioideae subfamily, which includes Citrus and its relatives.

The microbial pollution status of river surface water is important to ensure a river-based quality drinking water supply for the public. The present study aimed to investigate bacterial contamination status in the upper Mahaweli River, the main drinking water supplier to the hill country of Sri Lanka. Both the raw surface water and treated water, taken at 14 drinking water treatment plants (DWTPs) along the river segment of 60 km between Kotmale and Victoria reservoirs, were tested for total bacterial counts (TBC), total coliform counts (TCC) and faecal coliform counts (FCC).

Cancer is a major health challenge globally and in Sri Lanka. Providing comprehensive information to patients is crucial for improving treatment outcomes and patient satisfaction, supported by evidence of its effectiveness in managing cancer pain. EORTC QLQ-INFO25, an information module developed by the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Group, is aimed at assessing cancer patients' perception of information received during different phases of care.

Background: The global burden of metabolic diseases is increasing, but estimates of their impact on primary liver cancer are uncertain. We aimed to assess the global burden of primary liver cancer attributable to metabolic risk factors, including high body mass index (BMI) and high fasting plasma glucose (FPG) levels, between 1990 and 2021.

Methods: The total number and age-standardized rates of deaths and disability-adjusted life years (DALYs) from primary liver cancer attributable to each metabolic risk factor were extracted from the Global Burden of Disease Study 1990-2021.

Background: Despite the availability of antivenom, not all snakebite victims choose to seek allopathic care. This choice of care is likely to be determined by unexplored personal and external factors. We studied the factors influencing the choice of treatment and first aid measures among snakebite victims.

Background: Snakebite envenoming is a medical emergency that requires rapid access to essential medicines and well-trained personnel. In resource-poor countries, mapping snakebite incidence can help policymakers to make evidence-based decisions for resource prioritisation. This study aimed to characterise the spatial variation in snakebite risk, and in particular to identify areas of relatively high and low risk, in Eastern Province, Rwanda.

Haemotoxicity is the most common complication of systemic envenoming following snakebite, leading to diverse clinical syndromes ranging from haemorrhagic to prothrombotic manifestations. Key haematological abnormalities include platelet dysfunction, venom-induced consumption coagulopathy, anticoagulant coagulopathy and organ-threatening thrombotic microangiopathy. Diagnostic methods include the bedside whole blood clotting test, laboratory coagulation screening and other advanced methods such as thromboelastogram and clot strength analysis.

Snakebite-associated acute kidney injury (AKI) poses a significant health burden in the South Asia region, resulting in considerable morbidity and mortality. Multiple factors contribute to the pathogenesis of AKI following snakebites, including hypotension, intravascular haemolysis, disseminated intravascular coagulation, rhabdomyolysis, thrombotic microangiopathy (TMA) and direct nephrotoxicity. Clinical features manifest as anuria, oliguria, haematuria, abdominal pain and hypertension.

Article Synopsis
  • The rise of multidrug-resistant bacteria highlights the urgent need for new antimicrobial medicines, leading to the investigation of antimicrobial peptoids as potential alternatives.
  • Thirteen peptoid analogues were synthesized with varying alkyl side chains to analyze their antibacterial properties, and only one, called Tosyl-Octyl-Peptoid (TOP), showed significant broad-spectrum bactericidal activity.
  • TOP effectively kills bacteria in both dividing and non-dividing states, demonstrating promising minimum inhibitory concentrations and a high selectivity ratio, suggesting its potential as a future therapeutic option against resistant infections.

Triple-negative breast cancer (TNBC) is a highly aggressive and clinically challenging subtype of breast cancer, lacking the expression of estrogen receptor (ER), progesterone receptor (PR), and HER2/neu. The absence of these receptors limits therapeutic options necessitating the exploration of novel treatment strategies. Epigenetic modifications, which include DNA methylation, histone modifications, and microRNA (miRNA) regulation, play a pivotal role in TNBC pathogenesis and represent promising therapeutic targets.

  • The study examined the causes and outcomes of acute kidney injury (AKI) in 464 patients at a tertiary care center in Sri Lanka, highlighting the influence of age, comorbidities, and severity on patient prognosis.
  • Of the patients, 56.5% were male, with a mean age of 57.04 years; by 90 days, most patients showed improvement in renal function, though mortality rates were highest in those over 60 and with more severe AKI.
  • The research identified major challenges in AKI management, including inadequate resources and infrastructure, underscoring the importance of early identification and intervention for at-risk populations.

  • Relapsing polychondritis (RP) is a rare autoimmune disorder that causes recurring inflammation in cartilaginous tissues, affecting areas like the ears, nose, and joints.
  • A 68-year-old woman without prior health issues showed symptoms like hoarseness, polyarthritis, and nasal/ear involvement, leading to her RP diagnosis using the Modified McAdam criteria.
  • She was treated with intravenous cyclophosphamide and oral prednisolone, which improved her condition, while osteoporosis was treated with zoledronic acid, highlighting RP's role in patient assessments involving similar symptoms.

Introduction: Male infertility, defined as the inability to impregnate a fertile female, arises from various factors, among which sperm motility plays a pivotal role in determining reproductive potential. Seminal plasma, a complex fluid comprising diverse proteins, serves to nourish and support sperm, thereby facilitating their function within the female reproductive tract for successful conception. Normozoospermia denotes normal sperm motility in males, whereas asthenozoospermia indicates reduced sperm motility.

Introduction The Sri Lankan economic crisis that began in 2019 led to the suspension of cataract services in many districts. Although humanitarian missions were quick to supply materials, there was a lack of scientific evidence to predict the required intraocular lens power for patients with cataracts. This study aimed to assess the average lens power among patients from Trincomalee district, Sri Lanka, based on sex and age groups.

Aim: To determine the feasibility of combining the Hammersmith Infant Neurological Examination (HINE) and General Movements Assessment (GMA) within a standard follow-up schedule to predict developmental outcomes in infants at risk in low- and middle-income countries (LMICs).

Method: A total of 201 Sri Lankan infants (128 male, 73 female) were prospectively assessed with the GMA before 44 weeks (writhing movements) and at 3 to 4 months (fidgeting movements), followed by the HINE at 5 to 6 months. Developmental outcomes were assessed using the Bayley Scales of Infant and Toddler Development, Fourth Edition and clinical assessment after 24 months.
