Age related trends of the indices of hip structure help understanding how bone strength changes with age and the increased bone fragility in old age. Community-dwelling women aged 20-70years (n = 419) were selected by stratified random method and divided into age categories; 20-29years (n-69), 30-39years (n = 60), 40-49years (n = 69), 50-59years (n = 107) and 60-70years (n = 114). All subjects underwent dual energy x-ray absorptiometry (DXA) and hip structure analysis using Hologic Discovery scanner (Hologic Inc, Bedford, USA).

The determinants of body composition are likely to vary geographically due to the diversity of genetic and environmental factors between populations. Age-related trends in body composition in a population help understanding the health issues that are linked with different body compartments. In general, such studies are scarce in the South Asian region and this cross-sectional study examined the age-related trends in body composition in a selected group of healthy women aged 20-80 years in Sri Lanka.

Unlabelled: Refer ence values of bone turnover markers (BTMs) are determined by factors that are country-specific. In Sri Lanka, unavailability of BTM reference data has led to their non-use in management of osteoporosis. The results of this study can be used as reference data for women in Sri Lanka.

Introduction: Medicinal utility of lichens is ascribed to the presence of various secondary metabolites of low molecular weight and they have been used in traditional medicine including Ayurveda in the treatment of wounds and skin disorders. Despite the urgent need to effectively address the antibiotic resistance worldwide, the discovery of new antibacterial drugs has declined in the recent past. This emphasizes the increasing importance of investigating and developing new classes of antibiotics that can withstand antibiotic resistance.

Objectives: We evaluated the ability of fracture risk assessment tool (FRAX) Sri Lanka to discriminate between women with a recent fracture and without a fracture, when trabecular bone score (TBS) is added to the calculation.

Methods: We studied 394 women without previous fractures and 87 women who underwent dual energy X-ray absorptiometry within 3 months after the first fragility fracture. Fracture probabilities (FP) were estimated with and without TBS using Sri Lankan FRAX model and their ability to discriminate those with and without fracture was tested.

Article Synopsis
  • * The study involved preparing extracts from the whole plants and roots using hexane, ethanol, and water, and testing their effectiveness through disc diffusion and minimum inhibitory concentration (MIC) methods.
  • * Results showed that hexane extracts were particularly effective, with one plant inhibiting over 50% of MRSA strains at a low MIC of 0.012 mg/mL, highlighting the need for further research on the active compounds in these plants for potential therapeutic use.

Background: The quest for scientific endorsement of new drugs from plants continues due to the rising antibiotic resistance against pathogenic bacteria. is used in Sri Lanka in the treatment of infectious diseases. Therefore, antibacterial activity of plant extracts were evaluated against selected human pathogenic bacteria.

Purpose: Bone turnover markers (BTMs) are not widely used in clinical decision-making partly due to the wide variation of the reference values. This paper describes the geographical variation in BTMs reported from Asian countries.

Method: A systematic search was conducted using the PubMed, EMBASE, and Ovid.

Unlabelled: This paper describes age-specific BMD and TBS data of Sri Lankan women aged 20-70 years. No significant change of TBS and BMDs were seen between 20 and 50 years but a rapid decline was seen between 50 and 70 years. Prevalence of osteoporosis showed a marked difference when local reference data were used instead of manufacture provided data.

Article Synopsis
  • Antibiotic resistance is a major global issue, prompting scientists to explore plants used in traditional medicine for new drug development to combat resistant bacteria.
  • A study was conducted using extracts from five Sri Lankan medicinal plants to test their effectiveness against four pathogenic bacteria, employing methods like the agar disc diffusion test and minimum inhibitory concentration (MIC) analysis.
  • Results showed that certain ethanol, aqueous, and hexane extracts had significant antibacterial effects, with specific plants demonstrating the highest inhibition zones and promising MIC values, indicating their potential as sources for new antibacterial drugs.
