Nondestructive Analysis of Litchi Fruit Quality Using FT-NIR Spectroscopy

A non-destructive optical method based on near-infrared spectroscopy has been used for the evaluation of litchi fruit quality. Diffuse reflectance measurements (12500–3600 cm-1), physical, and biochemical measurements were performed individually on 100 litchi fruits of cv.Shahi cultivar harvested at different ripening stages. Relationships between spectral wavelengths and quality attributes were evaluated by application of chemometric techniques based on partial least squares (PLS) regression. The fruit set was divided into two groups: 60 fruits for calibration and 39 for validation. Good prediction performance was obtained for pH, soluble solids, and titratable acidity with correlation coefficients of 0.96, 0.91 and 0.94 respectively and root mean square errors of prediction of 0.009, 0.291ºBrix and 0.011% malic acid respectively. For the other quality traits such as vitamin C and color the prediction models were not satisfactorily accurate due to the higherror of calibration and prediction.

The prevalence and characteristics of disability in Eastern Nepal.

BACKGROUND: Disability is related to poverty and development. Enough information and documentation is not available for developing countries like Nepal. AIMS AND OBJECTIVES: To assess the self-reported prevalence of disability in terms of age, sex, types, cause and age of onset. METHODOLOGY: A cross-sectional house to house census was carried out by means of structured questionnaires. RESULTS: A total of 31,160 individuals (4.87%) were found disabled out of a total of 640,259 individuals. The three most common types of disability are physical affecting limbs, hearing and vision. The most common perceived cause of disability is inborn syndrome followed by injury/accidents. DISCUSSION: Various publications for the prevalence of reported disability show a figure between three and ten percent, with physical disability affecting locomotion and manipulation as the leading type of disability. The prevalence rate can vary depending upon the disability indicators, methods and population surveyed and perceptions of the people. CONCLUSION: The self-reported prevalence of disability in Sunsari District is 4.87%, with inborn-syndrome as the leading perceived cause.

Alcohol use among physicians in a medical school in Nepal.

OBJECTIVE: The objective of the study was to know about the use of alcohol among physicians and factors that were related to it. METHODS: This was a cross sectional study conducted among the physicians in a medical school of eastern Nepal. A semi structured questionnaire was used to collect information. RESULTS: There were 55 subjects in the study. Half of them were between 35-45 years age group and one fourth among them were female. There were more than 88% physicians consuming alcohol for more than 10 years. One third used to preferred whisky as their favorites drink. Use of alcohol among them was due to peer pressure and to become a social human being. Most of them drink alcohol occasionally with an average amount 30-60 ml in a sitting and usually in the evening. Most of the time, they use alcohol either in parties or at home. CONCLUSION: Alcohol use in Nepal is very much prevalent. The use of alcohol is socially accepted in many communities. Uses of alcohol by physicians have direct effect on their health as well as the health of many people because they are role model for many people. They are also in direct contact with the patients. Steps to council the physicians may reduce the consumption of alcohol.

Prevalence and determinants of unmet need for family planning in a district of eastern region of Nepal.

OBJECTIVES: The unmet need for family planning is defined as the discrepancy between individual's contraceptive behaviors and their stated fertility preferences--The extent of which is very high in developing countries like Nepal. This study explores the unmet need and its determinants. METHODS: Among the teaching district of B.P. Koirala institute of Health Sciences, in the Eastern Region of Nepal, a district was selected randomly to conduct a cross-sectional study. A total of 1079 women were selected using systematic random sampling. We compared different demographic variables and sex-ration to unmet need by using means, percentage and applied chi-squared test where applicable. RESULT: The extent of unmet need is 25 percent with 9.5 percent for spacing and 15.5 percent for limiting. The mean age at marriage is 16(+/-3.2) years. A strong association of gender preferences towards male child and unmet need exist, which is highly significant. CONCLUSION: Unmet need is high despite extensive family planning program in Nepal. Mean age at marriage below legal age, low female education and gender discrimination are the factors responsible for unmet need.

Impact of family health exercise program on health knowledge and practice of a rural population of eastern Nepal.

BACKGROUND: It is important to know the impact of health education on community. This may lead to improve the programs, commitment to students and staffs by taking feedback. These activities are aimed at producing changes in the community. OBJECTIVE: To assess the impact of health education as intervention program during Family Health Exercise (FHE) about the knowledge and practice of people related to health in a village of eastern Nepal. METHODS: During FHE, health education was given by the 3rd year medical students to the head of the 30 families. The neighbour 30 families were taken as control, where no health education was given. These two groups were compared after 6 months. RESULTS: Sanitary practice (Hand washing) before meal was known to both groups. But the material used for washing hand (soap and ash) was 53% in intervention as compared to 30% in control group. People were aware about the importance of care of the mother during pregnancy and lactation, but more in intervention group. The knowledge and practice for starting semisolid food other than breast milk for infants during weaning were higher in intervention (89%) than control (31%) group. CONCLUSION: There was significant change in the knowledge and practice of woman (mainly host) who received health education. The community also benefited in terms of their health knowledge and practices. Such programs are useful for the community at large.

Occurrence of aflatoxin in some of the food and feed in Nepal.

BACKGROUND: There are many contaminants like aflatoxin present in food products. Aflatoxin in comparison to many other contaminants is very toxic and also carcinogenic. There are reports of outbreak of aflatoxin toxicity in many parts of the world. AIM: To find out the level of aflatoxin in common food and feed. SETTING: The study was conducted in 16 districts of the Eastern region of Nepal. METHODS AND MATERIALS: Samples were collected from retailers and whole sellers from 1995 to 2003. Common food items that had high chances of infestation were collected. Food sample were taken to the laboratory to estimate the level of aflatoxin. The thin layer chromatography method was used to detect aflatoxin in the samples and comparison of fluorescence of sample spot with fluorescence of standard for estimation. RESULT: There were 832 samples for aflatoxin detection and estimation. One-third samples were found to be contaminated with aflatoxin. The highest percentage of contamination was found in peanut butter/vegetable oil (42.5%) and the lowest in areca nut (25%). Highest proportion of cornflakes samples were found to be contaminated with aflatoxin by more than the recommended value (30 ppb) and contamination in peanut was the lowest. CONCLUSION: People consume many common food items that contain aflatoxin. It is of high importance for the concerned department to give attention to this important public health issue. Even in small doses, continuous consumption can lead to many health problems. So it is of paramount importance to detect and control these contaminants in food items.

Attitude of women towards family planning methods and its use--study from a slum of Delhi.

BACKGROUND: To predict the need of family planning methods, family planning managers often rely on unmet need derived from measure of contraceptive demand. However women's intention and her background knowledge of family planning methods not received as much attention as a measure of family planning methods demand. OBJECTIVE: To know the attitude of women regarding use of family planning methods and to find out the factors that restricts its use, and the change in pattern of use over a period of one year. METHODS: This was a prospective study. One (Block G) out of eight blocks was selected randomly. Using convenient sample method, families were selected starting from a point in the selected block (Block G). 40 women of childbearing age group (15- 49 years) were enrolled. All women were followed for a period of one year. RESULTS: Weakness was narrated as the commonest side effect from all family planning methods. More than 70% women told that irregular menstruation from Oral Contraceptive pills and ill health from tubectomy as the other side effects. Demands for more children and for son preferences were the leading reason for not using any methods followed by afraid of side effects and health problems. There was negligible change in the use of family planning methods during the period of the study. CONCLUSION: Effective family planning methods use should be advocated through adequate counseling about the correct use, side effects and their proper management and their benefit in the back ground of custom and belief.
