TL;DR: The majority of older primary schoolchildren in Sri Lanka are undernourished, and Anaemia, vitamin A deficiency, iodine deficiency and soil-transmitted nematode infections affect a much smaller proportion of them.
Abstract: Objective To assess health status of 9-10-year old school children in Sri Lanka. Design A cross-sectional, descriptive study. Schools were selected to obtain a sample representative at national and provincial levels and 20 children were randomly selected from Grade 5 classes in each school. Measurements Children were examined for Bitot's spots and goitre. Height, weight, and visual acuity were measured according to standard procedures. Haemoglobin level was measured using finger-prick blood and a HemoCue® meter. Geohelminth infections were quantified by faecal examination using the modified Kato-Katz technique. Height for age Z-scores (HAZ) and body mass index (BMI) were calculated as indicators of nutritional status. Results Two thousand five hundred and twenty eight children (1351 boys) from 144 schools (140 state schools and four private schools) were examined. Nationally, 15.5% of children were stunted (HAZ lower than - 2.0 SD); 52.6% were thin (BMI 85th centile); 12.1% were anaemic; 0.3% had Bitot's spots; 3% had a visible or palpable goitre; 4.6% were shortsighted; and 6.9% had one or more soil-transmitted nematode infection. Among children on whom anthropometry, haemoglobin and faecal examinations were all done, 64.6% (1332/2063) were thin, stunted, anaemic or infected with worms. A much higher proportion of children in the Northern and Eastern provinces had health problems when compared to the other provinces. Conclusions The majority of older primary schoolchildren in Sri Lanka are undernourished. Anaemia, vitamin A deficiency, iodine deficiency and soil-transmitted nematode infections affect a much smaller proportion of them.

TL;DR: In this article, the authors describe the sedimentary characteristics of the 2004 Indian Ocean tsunami deposits in and around Periya Kalapuwa Lagoon, Sri Lanka and show that the tsunami deposits are 9 cm thick on average (up to 35 cm in the lagoon and up to 66 cm on the shore) and are composed mainly of medium sand (mean grain size 1.06 φ) with low mud content (0.61 ¼ ).

TL;DR: Experiments suggest that the photooxidation of MaG is mainly caused by O2*-, which is generated by an electron transfer from the excited HPDHC to ground-state oxygen, and iron(II) at pH 3.0 showed a higher rate of photodegradation due to the formation of extremely reactive hydroxyl radicals (HO*) upon dismutation of O2- anion through H2O2 intermediate.
Abstract: Reactive oxygen species (ROS), namely superoxide anion (O2*-, singlet oxygen (1O2), are potentially important substances for the mineralization of toxic organic molecules. The utility of hematoporphyrindihydrochloride (HPDHC) as a photosensitizer to generate ROS and their subsequent role in the destruction of magenta (MaG) in aqueous media is the main concern. The light irradiation of oxygenated aqueous solution of HPDHC and 1.5 x 10(-5) mol dm(-3) MaG at pH 3 yielded micromolar levels of NO3(-) ions. A higher rate of photodegradation (1.02 mol dm(-3) min(-1)) at pH 3 was observed compared to that of at pH 6 (0.68 mol dm(-3) min(-1)). Experiments were carried out in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO) as singlet oxygen (1O2) quencher and bezoquinone (BQ) as superoxide anion (O2*-) quencher. Only BQ was able to stop photodegradation suggesting that the photooxidation of MaG is mainly caused by O2*-, which is generated by an electron transfer from the excited HPDHC to ground-state oxygen. The presence of iron(II) at pH 3.0, compared to that without iron(II), showed a higher rate of photodegradation due to the formation of extremely reactive hydroxyl radicals (HO*) upon dismutation of O2*- anion through H2O2 intermediate. The formation of O2*-, H2O2, and HO* is therefore evident, which may act as active sites for subsequent photodegradation of MaG.

TL;DR: Both the prevalence of malnutrition and risk of malnutrition were commonly observed among community-dwelling older persons in Sri Lanka and the associated factors identified in this study might help public health professionals to implement necessary interventions that improve the nutritional status of this population.
Abstract: Malnutrition in older persons is a public health concern. This study aimed to estimate the prevalence of malnutrition and its associated factors among community-dwelling older persons in Sri Lanka. A cross-sectional study was conducted in the Kandy district, Sri Lanka. The nutritional status of older persons was assessed using the Mini Nutritional Assessment –Short Form (MNASF). A standardised questionnaire was used to record factors associated with malnutrition: demographic characteristics, financial characteristics, food and appetite, lifestyle, psychological characteristics, physical characteristics, disease and care, oral health, and social factors. Complex sample multinomial logistic regression analysis was performed. Among the 999 participants included in the study, 748 (69.3%) were females and 251 (25.1%) were males. The mean age was 70.80 years (95% CI: 70.13, 71.47). The prevalence of malnutrition, risk of malnutrition and well-nutrition was 12.5%, 52.4% and 35.1% respectively. In the multivariate model, hypertension (adjusted OR = 1.71; 95% CI: 1.02, 2.89), alcohol consumption (aOR = 4.06; 95% CI: 1.17, 14.07), and increased age (aOR = 1.06; 95% CI: 1.01, 1.11) were positively associated with malnutrition. An increased number of people living with the older person (aOR: 0.91; 95% CI: 0.85, 0.97) was a protective factor among those at risk for malnutrition. Both the prevalence of malnutrition and risk of malnutrition were commonly observed among community-dwelling older persons in Sri Lanka. The associated factors identified in this study might help public health professionals to implement necessary interventions that improve the nutritional status of this population.
