Intervention model is constructed for time series data and its comparison is done with ARIMA model. In our study we established superiority of intervention model over the ARIMA model. Using the share index data, we have shown that due to existence of external events, intervention model has lower residual variance and fits the data better.

Methods: This descriptive cross sectional study was carried out in a tertiary care, University Teaching Hospital (Shaikh Zayed Hospital, Lahore) from October 2010 to August 2011. Nasal swabs were taken from patients suffering from MRSA bacteraemia and were plated on mannitol salt agar plates to isolate Staphylococcus aureus (S. aureus) which were then tested for oxacillin susceptibility. Results: Nasal colonization was present in 52.5% of patients suffering from MRSA bacteraemia. Conclusion: Nasal colonization rates with MRSA were high among patients suffering from MRSA bacteraemia especially in those undergoing dialysis or surgical procedures. Therefore, screening and nasal decolonization should be practiced in hospitals.

Another objective of the study was to set a target for sediment quality that will sustain the health of the aquatic ecosystem for the long term. Sediments in the harbor were collected from different stations over two periods: a screening phase and a monitoring phase. Sediments were analyzed for a spectrum of parameters. Results showed that sediments in the harbor are characterized by a fine texture containing clay and silt different from what is found at a reference location in the Arabian Gulf. It appeared that sulfide, phosphorus, and total petroleum hydrocarbons (TPHs) levels are higher in sediments located in the inner and outer basins of the harbor compared with sediments in the main channel. Many metals are at higher levels in harbor sediments than those found in sediments from the reference location and are at hig...

The sensitivityand specificityof the 5 oligonucleotide probes were assessed using cell culture adapted rotavirus (RV) strains by carrying out hybridization at a fixed temperatureof 50. The results obtainedindicatethat a single hybridizationtemperature may be used for all the probes with virtuallyno decreasein specificityand sensitivity.

Heavy schoolbags may result in musculoskeletal and psychological problems among primary school children. This study was conducted to assess the weight of school bags in relation to primary school children weight, and to look for the prevalence of back pain among them in Al-Ahsa, Saudi Arabia. Methods-A total of 2567 school children were included in this study both from rural and urban areas of Al-Ahsa, Saudi Arabia. A cross sectional survey was conducted in which a pre-tested questionnaire was used to ask about demographic profile, and symptoms of back pain. The weight of the school bags and the school children was measured. Results-1860 school children (72.46%) out of 2567 were carrying bags of weight more than 15% of their body weight. The prevalence of heavy school bags was higher among the female children as compared with the male children. Back pain was reported by 42% of the school children. Conclusions-The weight of schoolbags of Al-Ahsa primary school children were higher than the internationally acceptable standards and as a result back pain was reported by 42% of school children. The school authorities and ministry of health should further evaluate and take the necessary steps to rectify the situation.

The study investigated the biological variables in height growth of Japanese twins and compared them with those of Japanese singletons. Samples of 92 boys and 99 girls from monozygotic twins, and 41 boys and 38 girls from dizygotic twins born in 1960-1973, from the Twin Class in the Junior and Senior High Schools affiliated to the University of Tokyo, Japan, were considered. The Bayes modal estimation method was applied to the triphasic generalized logistic growth model (BTT model). From the fitted model, the biological variables were extracted. The monozygotic twins, on average, matured earlier than dizygotic twins, but later than singletons. Until pre-adolescence, the height velocity of twin children is lower than that of singleton children. This results in the final stature of twin youths being smaller than that of singleton youths. The twins are, on average, about 2.6 cm smaller than singletons in final height only due to the lower velocity during birth to pre-adolescence. Comparing with the average final stature of dizygotic children, the boys were 3.9 cm and the girls were 2.8 cm shorter than Japanese late-maturing boys and girls, respectively. For monozygotic children, the boys were 3.8 cm and the girls were 3.0 cm shorter than the respective Japanese late-matured singleton boys and girls. The biological variables of twins differ significantly from those of singletons. It is important to recognize that singleton reference values do not correctly reflect the growth of twins.

A triphasic generalized logistic (BTT) model (Bock et al. [1994] Chicago: SSI) was used through the AUXAL software program. Growth parameters were derived from the estimated distance and velocity curves for each individual. A set of estimated growth parameters, including adult stature, was selected to develop equations, through the forward stepwise regression method, for the prediction of adult stature for Japanese boys and girls.
