Filter by:Research Problem: Upper respiratory infections (URIs) are a common reason for absence from schools as it is estimated that children get six to eight episodes every year. In Jazan (2013-2014), 34% of primary health care centre attendees who were complaining of URIs were under 15 years old and 42% of them were positive when tested for viruses by nasopharyngeal swabs. An intervention for URIs prevention is hand hygiene, as it has been shown to have an impact on reducing the risk of respiratory infections by 50% among children in Karachi, Pakistan by encouraging hand washing with soap. Another randomised controlled trial study conducted in Spain among primary school students showed a statistically significant 38% reduction in the absenteeism rate due to URIs in the intervention group who received education about hand hygiene and used hand sanitisers which were distributed among schools. Also, the Chinese conducted a cluster randomised control trial evaluating the effect of a hand washing programme and revealed a 38% reduction in absence due to URIs among primary schoolchildren. This preventive measure is questionable, as a randomised controlled trial done among primary school students in New Zealand revealed that encouraging the use of hand sanitisers in schools did not have an impact on reducing acute respiratory infections or absenteeism. The questionable effect was also documented in a systematic review and meta-analysis for randomised controlled trials about the effectiveness of hand hygiene in decreasing absences through illness in educational settings. Research Significance: Appropriate hand hygiene is recommended as a non-pharmacological preventive measure against respiratory infections. But this preventive measure is questionable as the results of randomised controlled trials about the effectiveness of different hand hygiene interventions in reducing absence due to upper respiratory tract infection in different educational settings are controversial. Furthermore, previous studies of hand hygiene interventions were low in quality and it is recommended to improve future studies relating to it. Also, there is no research on the effectiveness of these measures in Saudi Arabia. So, this piece will add new knowledge to local and international literature. In addition, this study may help the school health administration to develop a hand hygiene programme. Objectives: - To determine if hand hygiene education is associated with school absence rates due to URIs reduction among primary schoolgirls in Riyadh city, 2017-2018 - To measure post-intervention total primary schoolgirl's absence rate (both groups) in Riyadh city, 2017-2018. - To measure post-intervention primary schoolgirls' absence rate due to upper respiratory infections (both groups) in Riyadh city, 2017-2018. Methodology: Cluster RCT will be conducted among primary schoolgirls attending public schools in Riyadh city in the first education semester. Sampling will be multistage to end up with four schools. 616 schoolgirls who are attending the selected classes will be invited to the study. Two schools will be randomly assigned to the intervention, which includes one-hour hand washing workshop at the beginning of the study, in addition to posters. Parents will self-administer the questionnaire at baseline, in addition to a follow-up phone interview questionnaire.
Retrospective study in the 3 intensive care units of the Brest Teaching Hospital (France) during a 18-months period (June 2014 -December 2015) to study the independent association between hypophosphatemia and 90-day mortality.
Helicobacter pylori (H. pylori) is the most common chronic bacterial infection in humans. The prevalence of H. pylori is about 30~50% in the Western adult population. It is estimated that about 50% of people are infected with this bacterium in Taiwan. Many studies have shown that H. pylori is an important causal factor of chronic gastritis, peptic ulcer disease, gastric cancer and gastric lymphoma. The World Health Organization classified H. pylori as a Group 1 carcinogen in 1994. Endoscopic examination is indicated to confirm the above diagnosis for patient with H. pylori infection. Eradication of H. pylori infection reduces the risk of gastric cancer and recurrence of peptic ulcer disease. However, the eradication rate of clarithromycin-based triple therapy has been declining in recent years, probably related to the increasing resistant rate to clarithromycin. Several strategies have been proposed to overcome the declining eradication rate, including (1) extending the treatment duration of triple therapy to 14 days; (2) the use of bismuth quadruple therapy which contains bismuth, a proton pump inhibitor, and two antibiotics (usually metronidazole and tetracycline); (3) non-bismuth quadruple therapy (concomitant therapy) which contains a proton pump inhibitor and three antibiotics (usually amoxicillin, metronidazole, and clarithromycin); (4) sequential therapy which contains a proton pump inhibitor (PPI) plus amoxicillin for five days, followed by a PPI plus clarithromycin and tinidazole for another five days. The investigators aim to evaluate the efficacy of Metronidazole powder in the Intraluminal therapy for Helicobacter pylori infection while an endoscopic examination is performed.
The aim is to explore the human urine composition and its relation to urine tract infections

The purpose of this project is to beta-test a brief waiting room video intervention that promotes early initiation of antiretroviral treatment among treatment-naïve HIV-positive patients, adherence to antiretroviral treatment and retention in care among HIV-positive patients currently on therapy, sexual risk reduction tailored to HIV-positive persons, and patient-initiated discussion of these topics with their health providers. The video is currently being created, and will be ready for beta-testing by June 1, 2016. Results of the beta-testing will be used to refine and improve the video before dissemination to HIV/AIDS treatment facilities nationally. This video project is being funded by the Centers for Disease Control and Prevention, Division of HIV/AIDS Prevention (DHAP).
Assessment of meropenem plasma concentration in critically ill patients who require CRRT (continuous renal replacement therapy). A standard dose of meropenem is administered, i.e. 1 gram every 8 hours.
Childhood fever is a prevalent problem. Most febrile children who visit hospital improve without treatment, but a minority require treatment, and a few will have severe disease. The investigators want to improve the diagnosis and management of febrile children by developing tests to distinguish between bacterial and viral disease so that antibiotic treatment can be initiated promptly and only when required. Judicious and prudent use of antibiotics will reduce the likelihood of developing resistant organisms and save treatment costs. The investigators will prospectively recruit acutely febrile children presenting to hospital, collecting research samples for validation of biomarkers, in combination with clinical phenotypic markers and host genetic markers (BIVA-studies). Any febrile child newborn to under 18 presenting to hospital will be eligible for recruitment. The study will last 5 years.
