BackgroundEpidemiology and surveillance of neonatal sepsis helps in implementation of rational empirical antibiotic strategy.ObjectiveTo study the frequency of bacterial isolates of early onset neonatal sepsis (EONS) and their sensitivity pattern.MethodsIn this retrospective study, a case of EONS was defined as an infant who had clinical signs or born to mothers with potential risk factors for infection, in whom blood culture obtained within 72 hours of life, grew a bacterial pathogen. Blood culture sample included a single sample from peripheral vein or artery. Relevant data was obtained from the unit register or neonatal case records.ResultsOf 2182 neonates screened, there were 389 (17.8%) positive blood cultures. After excluding coagulase-negative Staphylococci (160), we identified 229 EONS cases. Preterm neonates were 40.6% and small for gestational age, 18.3%. Mean birth weight and male to female ratio were 2344.5 (696.9) g and 1.16:1 respectively. Gram negative species represented 90.8% of culture isolates. Pseudomonas (33.2%) and Klebsiella (31.4%) were common among them. Other pathogens included Acinetobacter (14.4%), Staphylococcus aureus (9.2%), E.coli (4.4%), Enterobacter (2.2%), Citrobacter (3.1%) and Enterococci (2.2%). In Gram negative group, best susceptibility was to Amikacin (74.5%), followed by other aminoglycosides, ciprofloxacin and cefotaxime. The susceptibility was remarkably low to ampicillin (8.4%). Gram positive group had susceptibility of 42.9% to erythromycin, 47.6% to ciprofloxacin and above 50% to aminoglycosides. Of all isolates, 83.8% were susceptible to either cefotaxime or amikacinConclusionGram-negative species especially Pseudomonas and Klebsiella were the predominant causative organisms. Initial empirical choice of cefotaxime in combination with amikacin appeared to be rational choice for a given cohort.

Multisensory stimulation appears to have a beneficial effect on the tonal maturation in preterm infants. However, further studies are warranted to investigate the long-term effects of multisensory stimulation on neurodevelopmental outcome in preterm infants.

Mind project: a school-based environmental approach for preventing weight gain in children. Obesity. 2007;15: 906 -917. Objective: The Wise Mind pilot study compared the efficacy of an environmental approach for prevention of inappropriate weight gain in children with an active control condition that used an environmental approach for modifying expectancies related to the use of alcohol, tobacco, and drugs. Research Methods and Procedures:A total of 670 second to sixth grade students from four schools were enrolled in the study. The study spanned 2 academic years, and 586 students were available for evaluation at the end of the study. Two schools were randomly assigned to each treatment arm. The environmental approach for weight gain prevention focused on modification of eating habits and physical activity, and the active control group focused on modification of expectancies related to substance use. Results: Using an intention to treat design, the study found no differences in weight gain prevention between the two interventions. The weight gain prevention program was associated with reduction of total caloric intake, reduction of dietary fat intake, reduction of protein intake, and increased physical activity in comparison with the active control group and relative to baseline. These changes in food intake were attributed to changes in food selections that resulted from modification of school cafeteria menus and food preparation. Discussion: The Wise Mind school-based weight gain prevention program induced behavioral changes in healthy eating and physical activity but did not induce significant changes in body weight in comparison with the control arm. Recommendations for future research are provided.

We describe a novel method to monitor pulse rate (PR) on a continuous basis of patients in a neonatal intensive care unit (NICU) using videos taken from a high definition (HD) webcam. We describe algorithms that determine PR from videoplethysmographic (VPG) signals extracted from multiple regions of interest (ROI) simultaneously available within the field of view of the camera where cardiac signal is registered. We detect motion from video images and compensate for motion artifacts from each ROI. Preliminary clinical results are presented on 8 neonates each with 30 minutes of uninterrupted video. Comparisons to hospital equipment indicate that the proposed technology can meet medical industry standards and give improved patient comfort and ease of use for practitioners when instrumented with proper hardware.

This review is a novel attempt to explore the LTF among NHS studies, reasons for LTF and strategies to reduce LTF. This review can act as a basis for planning and execution of effective NHS programs.

LighterLife Total is a very low calorie diet total dietary replacement weight reduction programme that provides Foodpacks, behavioural change therapy and group support appropriate for people with a body mass index of 30 kg m(-2) or above. A model was built to assess the cost-effectiveness of LighterLife Total, compared with (i) no treatment, Counterweight, Weight Watchers and Slimming World, as a treatment for obesity in those with a body mass index of 30 kg m(-2) or above, and (ii) no treatment, gastric banding and gastric bypass in those with a body mass index of 40 kg m(-2) or above. Change in body mass index over time was modelled, and prevalence of comorbidities (diabetes, coronary heart disease and colorectal cancer) was calculated. Costs (of intervention and treatment for comorbidities) and quality-adjusted life years were calculated. LighterLife Total was cost-effective against no treatment, Counterweight, Weight Watchers and Slimming World in the 30+ kg m(-2) group (incremental cost-effectiveness ratios: £11 895, £12 453, £12 585 and £12 233, respectively). In the 40+ kg m(-2) group, LighterLife Total was cost-effective against no treatment (incremental cost-effectiveness ratio: £4356), but less effective than gastric banding and bypass.
