Cross-sectional Study Involving (cross-sectional + study_involving)
Selected AbstractsEthnicity and glycaemic control are major determinants of diabetic dyslipidaemia in MalaysiaDIABETIC MEDICINE, Issue 6 2001I. S. Ismail Abstract Aims To define the prevalence of dyslipidaemia in young diabetic patients in Peninsular Malaysia and the contributory factors of dyslipidaemia in these subjects. Methods This is a cross-sectional study involving 848 young diabetic patients from seven different centres, with representation from the three main ethnic groups. Clinical history and physical examination was done and blood taken for HbA1c, fasting glucose, total cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol and triglycerides. Results The overall lipids were suboptimal, worse in Type 2 diabetes mellitus (DM) patients compared with Type 1 DM patients. Of the Type 2 patients, 73.2% had total cholesterol >,5.20 mmol/l, 90.9% had LDL-cholesterol >,2.60 mmol/l, 52.6% had HDL-cholesterol <,1.15 mmol/l and 27.3% had serum triglycerides >,2.30 mmol/l. There were ethnic differences in the lipid levels with the Malays having the highest total cholesterol (mean 6.19 mmol/l), and the highest LDL-cholesterol (mean 4.16 mmol/l), while the Chinese had the highest HDL-cholesterol (geometric mean 1.24 mmol/l). Ethnicity was an important determinant of total, LDL- and HDL-cholesterol in Type 2 DM, and LDL- and HDL-cholesterol and triglycerides in Type 1 DM. Glycaemic control was an important determinant of total, LDL-cholesterol and triglycerides in both Type 1 and Type 2 DM. Waist,hip ratio (WHR) was an important determinant of HDL-cholesterol and triglycerides in both types of DM. Gender was an important determinant of HDL-cholesterol in Type 2 DM, but not in Type 1 DM. Socioeconomic factors and diabetes care facilities did not have any effect on the dyslipidaemia. Conclusions The prevalence of dyslipidaemia was high especially in Type 2 DM patients. Ethnicity, glycaemic control, WHR, and gender were important determinants of dyslipidaemia in young diabetic patients. Diabet. Med. 18, 501,508 (2001) [source] Risk factors for injuries to maxillary permanent incisors and upper lip among schoolchildren in Dar es Salaam, TanzaniaINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 2 2009FEBRONIA KOKULENGYA KAHABUKA Background.,, Dental trauma is common among children, and the maxillary permanent central incisors are the most often affected teeth. Aim.,, This study aimed to investigate the risk factors for injury to maxillary permanent incisors and the upper lip among Tanzanian schoolchildren aged 8,14 years. Design.,, A cross-sectional study involving 1119 children. The risk variables investigated included age, gender, lip competence, and overjet. The corresponding proportions of injuries and the relative risk (with 95% confidence interval) were calculated and tested by Fisher's exact test. Logistic regression was applied to ascertain the strength and direction of the association of the risk variables to injuries, and backward selection was used to test significant risk factors. Results.,, About 24% of the children had trauma to maxillary incisors, 45% had incompetent lip whereas 31% had increased overjet. Age, gender, overjet, and lip competence showed significant association with injuries to upper lip and maxillary incisors. Boys had sustained more injuries than girls, with a higher relative risk for luxation injuries. Enamel fracture was associated with overjet combined with lip competence, whereas enamel dentine fracture without pulp involvement was related to gender. Luxation injuries were associated with gender, tooth avulsion with overjet, and lip competence. Injury to the upper lip was associated with age. Conclusion.,, Male gender, increased overjet, and lip incompetence were the main risk factors of getting trauma to maxillary incisors, whereas age was the risk factor for injury to the upper lip. [source] Assessment of acid-base status of cats with naturally occurring chronic renal failureJOURNAL OF SMALL ANIMAL PRACTICE, Issue 2 2003J. Elliott Metabolic acidosis is reported to be a common complication of feline chronic renal failure (CRF) but acid-base status of feline patients with this disease is rarely assessed by general practitioners. A cross-sectional study involving 59 cases of naturally occurring feline CRF was conducted to determine the prevalence of acid-base disturbances. Cases were categorised on the basis of their plasma creatinine concentrations as mild, moderate or severe. A group of 27 clinically healthy, age-matched cats was assessed for comparison. A low venous blood pH (<7·270) was found in 10 of the 19 severe cases (52·6 per cent), three of the 20 moderate cases (15 per cent) and none of the 20 mild cases. Acidaemia was associated with an increased anion gap contributed to by both low plasma bicarbonate and low chloride ion concentrations. Biochemical analysis of urine samples showed urine pH to decrease with increasing severity of renal failure. Urinary loss of bicarbonate was not associated with the occurrence of acidaemia and there was a tendency for urinary ammonium ion excretion to decrease as the severity of renal failure increased. Cats with naturally occurring CRF do not show plasma biochemical evidence of acid-base disturbances until the disease is advanced. [source] Clinical teaching and clinical outcomes: teaching capability and its association with patient outcomesMEDICAL EDUCATION, Issue 7 2006Ophyr Mourad Background, There is little research on the impact of medical education on patient outcome. We studied whether teaching capability is associated with altered short-term patient outcomes. Methods, We performed a multicentre retrospective cross-sectional study involving 40 clinician teachers who had attended on the general internal medicine services in hospitals affiliated with the University of Toronto along with the clinical outcomes of consecutive patients treated for community-acquired pneumonia, congestive heart failure, chronic obstructive pulmonary disease and gastrointestinal bleeding (n = 4377) between 1999 and 2001. Doctors were characterised by teaching effectiveness scores (n = 677) as high-rated or low-rated according to house staff ratings. Results, There was no correlation between the teaching effectiveness scores and the mean length of stay for those patients treated for community-acquired pneumonia (high-rated = 10.3 versus low-rated = 8.1 days, P = 0.058), congestive heart failure (high-rated = 10.1 versus low-rated = 9.9 days, P = 0.978), chronic obstructive pulmonary disease (high-rated = 9.4 versus low-rated = 9.9 days, P = 0.419) and gastrointestinal bleeding (high-rated = 6.3 versus low-rated = 6.8 days, P = 0.741). In addition, we observed no significant correlation between teaching effectiveness scores and 7-day, 28-day and 1-year readmission rates for all pre-specified diagnoses. Conclusion, There is no large correlation between teaching effectiveness scores and short-term patient outcomes, suggesting that doctor teaching capabilities, as perceived by house staff, does not generally impact clinical care. [source] Dental caries experience in young Australian Army recruits 2008AUSTRALIAN DENTAL JOURNAL, Issue 4 2009MS Hopcraft Abstract Background:, Recent studies have shown a substantial decline in caries experience in Australian Army recruits between 1996 and 2002,2003, and in Australian adults between 1987,1988 and 2004,2006. However, studies in children have reported an increasing trend in caries experience between 1998 and 2002. The aim of this study was to investigate caries experience in Australian Army recruits in 2008. Methods:, A cross-sectional study involving 1084 Australian Army recruits was conducted from January to May 2008. Data were obtained from a clinical dental examination with bitewing radiographs, and a questionnaire elicited socio-demographic data and history on lifetime exposure to fluoridated drinking water. Results:, Mean DMFT scores were 3.16, 4.08, 5.16 and 7.11 for recruits aged 17,20, 21,25, 26,30 and 31,35 years, respectively. Recruits with a lifetime exposure to fluoridated drinking water had a mean DMFT of 3.02, while recruits with no exposure had a mean DMFT of 3.87. Conclusions:, Caries experience in Australian Army recruits aged 17,25 years increased between 2002,2003 and 2008. Recruits with lifetime exposure to fluoridated drinking water had 25 per cent less caries experience compared with recruits who had no exposure to fluoridated drinking water after adjusting for the effects of age, gender, education and socio-economic status.
