Filter by:Dysphagia in hospitalized elders is associated with less positive outcomes in rehabilitation, increased likelihood of readmission, increased comorbidity and mortality, and increased length of hospital stay. In light of an increase in the elderly population in Denmark, the consequences of dysphagia, and the importance of minimizing the risk of disability and frailty, it is vital to emphasize safe participation of the elderly dysphagic patient in eating, drinking and swallowing. Danish occupational therapists have an important role in the dysphagia management, but no Danish evidence-based occupational therapy assessments for dysphagia of elderly medical patients exist. In order to oblige this lack, the objective of the study is to provide an assessment tool with operational definitions of dysphagia which includes the complexity of performance in eating, drinking and swallowing, is evidence-based, and guides occupational therapists in the treatment planning in a client-centred and purposeful manner. The study involves a quantitative approach, and is initiated by a translation and cultural adaptation of the Canadian "The McGill Ingestive Skills Assessment" (MISA). Hereafter, the psychometric qualities are tested. On basis of the data collected for the psychometrics, the prevalence and characteristics of dysphagia in the study population are investigated. Provided that the psychometric testing of the MISA reveals satisfactory levels, the effect of using the MISA in the treatment planning is investigated. It is hypothesized that: The Danish translation of the MISA will demonstrates satisfactory content validity, reliabilities, convergent validity, known-groups validity, predictive validity, criterion validity, high levels of sensitivity/specificity and are responsive to change. Dysphagia is prevalent in elderly medical patients at the time of admission to acute medical care and there can be found a correlation between dysphagia severity and the presence of comorbidity, disability, frailty, the length of hospital stay, the place of discharge and the number of readmissions for elderly medical patients.
The purpose of this study is to improve antibiotic prescribing practices of Mexican primary care physicians for patients seeking care for acute respiratory tract infections (ARIs). The investigators will employ a combination of qualitative and quantitative methods to develop and evaluate a patient education and physician decision-support intervention. Hypothesis 1: The investigators will identify barriers and facilitators of appropriate antibiotic use for ARIs that can be addressed through patient education and physician decision-support. Hypothesis 2: The proportion of patients who report desire for antibiotics as a "very important" reason for seeking care will decrease from 50% to 30% following exposure to the educational intervention; and 90% (95% confidence interval: 80% to 100%) of patients will report that they trust the information provided by the computer. Hypothesis 3: Antibiotic prescribing for adults with uncomplicated acute bronchitis will decrease from 80 percent to 40 percent following the introduction of a real-time clinical decision support tool.
The aims of this study are to characterise the clinical efficacy and virological clearance dynamics of orally administered oseltamivir in patients with influenza caused by novel influenza A(H1N1). This research will also contribute to enhancing research capacity in affected countries. The objectives are to assess the: - viral replication levels over time in affected patients - antiviral efficacy of oral oseltamivir - patterns and compartments of viral shedding, tissue distribution - innate inflammatory response and relation to viral replication - kinetics of antibody response - antiviral sensitivity of influenza viruses at baseline and during oseltamivir treatment using in vitro and molecular methods - pharmacokinetic characteristics of oseltamivir and oseltamivir carboxylate - all cause in hospital mortality - clinical and radiological features, disease course and outcome - length of stay in hospital - risk factors associated with development of severe disease and death
The primary objective is to assess the safety and tolerability of two consecutive doses of plant-based H5 VLP, (H5N1) pandemic influenza vaccine combined with Alhydrogel®, given 21 days apart, at three dose levels: 5µg, 10µg and 20µg., compared to the placebo, and combined with Alhydrogel®.
Inappropriate use of antibiotics to treat patients with acute bronchitis is a significant factor contributing to the selection of antimicrobial drug resistant pathogens, which threaten the effectiveness of available therapies to treat common community-acquired bacterial infections. A key factor driving overuse of antibiotics is inaccurate estimation of pneumonia risk among patients with acute cough illnesses. This study will use a cluster randomized trial design within the Geisinger Health System's integrated clinic network to measure the efficacy of an algorithm driven clinical decision support tool to safely reduce the frequency of unnecessary antibiotic prescriptions for adult patients with lower respiratory tract infections.
The purpose of this study is to determine the degree of indirect benefits to family members and classmates resulting from administration of influenza vaccine to children.
The purpose of this study is to test the effectiveness of an enhanced oral hygiene protocol in preventing pneumonia among nursing home residents.
The primary safety objective of this study is to assess the safety of split- virion inactivated H1N1 vaccine with and without adjuvant when administered at the 7.5,15 or 30 mcg dose. The primary immunogenicity objective is to assess the antibody response following each dose of split- virion inactivated A(H1N1) vaccine with and without adjuvant. Participants will include up to 2200 healthy persons age 3 and older who have no history of novel influenza H1N1 2009 infection or novel influenza H1N1 2009 vaccination. This is a randomized, double-blinded, Phase II study in healthy males and non-pregnant females, aged 3 years and older. Subjects will be stratified by elders (equal to or more than 61 years), adults (18-60 years), adolescents (12-17 years) and children (3-11 years), elders and adolescents will be randomized into 5 dose groups (adjuvanted H1N1 vaccine of 7.5,15 or 30 mcg per dose or non-adjuvanted H1N1 vaccine of 15 or 30 mcg per dose), children will be randomized into 4 dose groups (adjuvanted H1N1 vaccine of 7.5 or 15 mcg per dose or non-adjuvanted H1N1 vaccine of 15 or 30 mcg per dose), adults will be randomized into 6 dose groups (adjuvanted H1N1 vaccine of 7.5,15 or 30 mcg per dose or non-adjuvanted H1N1 vaccine of 15 or 30 mcg per dose or placebo), 110 subjects per dose and age stratum will be to receive intramuscular influenza H1N1 vaccine. The H1N1 vaccine will be administered at Day 0 and Day 21. Following immunization, safety will be measured by assessment of adverse events through 21 days following the last vaccination (Day 42 for those receiving both doses), serious adverse events and new-onset chronic medical conditions through 6 months post the final vaccination (Day 180 after second vaccination), and reactogenicity to the vaccine for 8 days (Day 0-7) following each vaccination. Immunogenicity testing will be hemagglutination inhibiting (HAI) on serum obtained on the day 21 of each vaccination (prior to vaccination), on Day 21 after first vaccination, and 21 days following the second vaccination (Day 42).
The investigators earlier clinical study in 754 young Finnish men demonstrated a significant negative association of serum 25-OHD concentration with acute respiratory tract infections. The present study aimed to determine whether vitamin D supplementation may decrease the incidence of acute respiratory tract infections.
Diarrheal diseases are a major cause of morbidity and mortality globally in children less than 5 years of age. Prolonged diarrhea, recurrent infections and growth failure in developing countries are usually a consequence of micronutrient deficiencies including zinc. The primary aims of the proposed study are to evaluate the effect of the use of multiple micronutrient sprinkles including zinc on compliance of supplement use and the incidence of recurrent diarrheal and respiratory illnesses. The proposed study will be conducted at the Fima Lifshitz Metabolic Research Center, Department of Pediatrics, Universidade Federal Da Bahia, Salvador-Bahia, Brazil over a period of 18 months. This is a double-blind placebo-controlled trial involving the use of 2 types of micronutrient sprinkles in a group of 120 children who attend a day care center in Salvador, Bahia. They will be randomized into 2 groups of 60 children each. The intervention group will receive sprinkles containing zinc while the control group will receive micronutrient sprinkles without zinc. The primary outcome variables of interest are zinc status, stool zinc losses and diarrhea duration. Both groups of infants will be monitored at monthly intervals for an initial duration of 180 days for zinc status, diarrhea episodes, respiratory illness and growth. This study will allow for the establishment of a cohort of children who will be monitored in a micronutrient supplementation trial using sprinkles.
