Knowledge and awareness levels of diabetes mellitus risk factors among nondiabetic visitors of primary health care centers: a multicenter study.

OBJECTIVE: People with a high risk of developing Type 2 Diabetes Mellitus are primarily due to lifestyle factors and can be reduced by implementing awareness programs. Therefore, this study evaluates the diabetic awareness level, risk factors, and lifestyle behaviors among nondiabetic participants. PATIENTS AND METHODS: This is a cross-sectional study conducted among 538 nondiabetic participants based on American Diabetic Association (ADA) parameters via face-to-face interview. The sample was collected from five different primary health care centers from November 2019 to February 2020. The target population was nondiabetic with age ≥18 years and participants with other serious chronic illnesses, pregnant women, or unable to communicate effectively were excluded. RESULTS: A total of 538 participants without diabetes data were analyzed, of which 363 (67.5%) were males. Good, moderate, and insufficient knowledge of Type 2 Diabetes Mellitus awareness was 34.6%, 52.4%, and 13.0%, respectively. The knowledge level in females' participants was significantly less than the males (OR=2.4; p=0.0005). About 44% had diabetic risk, and the prevalence of diabetes risk was significantly high in males (OR=1.7), obesity (OR=2.9), overweight (OR=2.3), and high blood pressure (OR= 2.2) (all p < 0.05). The risk of diabetes was increased in those participants who consumed more bakery items (p < 0.05). The diabetes risk score was negatively associated with diabetes awareness levels (r= -0.29, p= 0.063). CONCLUSIONS: The risk of diabetes in the general population can be prevented by proactive public health awareness campaigns, particularly among elderly age group, with lower educational level, physically inactive, and obese.

Vitamin D status and abdominal aortic calcification in postmenopausal women.

Vitamin D has an important role in bone metabolism and may be involved in the process of vascular calcification. The objective of this study was to evaluate the effect of vitamin D status on the presence of abdominal aortic calcification (AAC). We enrolled, in a cross-sectional study, 429 postmenopausal women [mean age, weight, and BMI of 59.5 ± 8.3 (50-83) years, 75.8 ± 13.3 (35-165) kg, and 29.9 ± 5.2 (14.6-50.8) kg/m2, respectively]. Lateral vertebral fracture assessment (VFA) images and scans of the lumbar spine and proximal femur were obtained using a Lunar Prodigy densitometer. Vertebral fractures (VFs) were defined using the Genant semiquantitative (SQ) approach. We used the Kauppila score to assess AAC extension. Clinical risk factors of osteoporosis were collected, and 25-hydroxy vitamin D was measured using electrochemiluminescence (Roche). Prevalence of osteoporosis and hypovitaminosis D (<20 ng/ml) was 21.0% and 78.1%, respectively. VFs grade 2/3 were identified in 76 patients (17.7%). Two thirds of the evaluable participants did not have any detectable AAC. The prevalence of significant atherosclerotic burden, defined as a radiographic 24-point AAC score of 5 or higher, was 7.9%. The group of women with extended AAC were older and had a statistically significant higher menopause duration and more prevalent grade 2/3 VFs. Compared to women with normal values of vitamin D, women with vitamin D insufficiency (<20 ng/ml) and deficiency (<10 ng/ml) had a lower BMD and more prevalent VFs. No difference was noted with regard to AAC among the three groups. Multiple stepwise conditional logistic regression analysis showed that the presence of AAC was associated significantly with age and the presence of VFs. Extended aortic calcifications are independently associated with prevalent VFA-identified VFs but not with serum vitamin D levels in postmenopausal women. VFA imaging using DXA may detect at the same time prevalent VFs and AAC, an important cardiovascular disease risk factor.

Influence of obesity on vertebral fracture prevalence and vitamin D status in postmenopausal women.

BACKGROUND: It is well established that weight is an important determinant of bone health. Whereas obesity is associated with increased mortality and morbidity from diabetes and cardiovascular diseases, high body weight is widely believed to be associated to hypovitaminosis D and protective against the development of osteoporosis and fracture risk. The objective of the study was to evaluate the effect of BMI on vitamin D status and on densitometric vertebral fractures (VFs) in a large series of asymptomatic women aged over 50 who had a VFA examination during their bone mineral density (BMD) testing. METHODS: We enrolled 429 postmenopausal women (mean age, weight and BMI of 59.5 ± 8.3 (50 to 83) years, 75.8 ± 13.3 (35 to 165) kgs and 29.9 ± 5.2 (14.6 to 50.8) kg/m(2), respectively. Lateral VFA images and scans of the lumbar spine and proximal femur were obtained using a Lunar Prodigy densitometer. VFs were defined using the Genant semiquantitative (SQ) approach. Clinical risk factors of osteoporosis were collected and 25-hydroxivitamin D was measured using electrochimiluminescence (Roche). RESULTS: Prevalence of osteoporosis and hypovitaminosis D (<20 ng/ml) was 21.0 % and 78.1 % respectively. VFs grade 2/3were identified in 76 (17.7 %). Comparison between women according to their BMI showed that obese women had a higher BMD and less proportion of women with osteoporosis and VFs grade 2/3 than lean and overweight women. The prevalence of VFs globally increased with age and as BMI and BMD declined. Stepwise regression analysis showed that the presence of osteoporosis was independently related to BMI and history of fractures while the presence of grade 2/3 VFs was independently related to age, hypovitaminosis D and years of menopause. CONCLUSION: Obese women had a higher BMD and lower prevalence of VFs. VFs were significantly related to age, hypovitaminosis D and years since menopause. However, among obese women, prevalence of VFs was increased in osteoporotic women.

Vertebral fractures and abdominal aortic calcification in postmenopausal women. A cohort study.

INTRODUCTION: Vertebral fracture assessment (VFA) imaging with a bone densitometer can simultaneously detect prevalent vertebral fractures (VFs) and abdominal aortic calcification (AAC). OBJECTIVE: To study the relation between the prevalence of VFs using VFA in asymptomatic women and the prevalence and severity of AAC. DESIGN: This is a cross-sectional study. SETTINGS: Subjects were recruited in a third care center from asymptomatic women selected from the general population. PARTICIPANTS: We enrolled 908 post-menopausal women with a mean age of 60.9 years ± 7.7 (50 to 91) with no prior known diagnosis of osteoporosis or taking medication interfering with bone metabolism. PRIMARY AND SECONDARY OUTCOME MEASURES: Lateral VFA images and scans of the lumbar spine and proximal femur were obtained using a GE Healthcare Lunar Prodigy densitometer. VFs were defined using a combination of Genant semiquantitative (SQ) approach and morphometry. VFA images were scored for AAC using a validated 24 point scale. RESULTS: VFA images showed that 179 of the participants (19.7%) had at least one grade 2/3 VF, 81% did not have any detectable AAC whereas the prevalence of significant atherosclerotic burden, defined as AAC score of 5 or higher, was 12%. The group of women with 2/3 VFs had a statistically significant higher AAC score and higher proportion of subjects with extended AAC, and lower weight, height, and lumbar spine and hip BMD and T-scores than those without VFA-identified VFs. Multiple regression analysis showed that the presence of grade 2/3 VFs was significantly associated with age, BMI, history of peripheral fracture, AAC score ≥ 5 and densitometric osteoporosis. CONCLUSION: In post-menopausal women, extended AAC is independently associated with prevalent VFs regardless of age, BMI, history of fractures, and BMD.

Age-adjusted incidence rates of hip fractures between 2006 and 2009 in Rabat, Morocco.

UNLABELLED: This study, characterizing the incidence of hip fracture in the province of Rabat, showed that age- and sex-specific rates remained stable between 2006 and 2009. The demographic projections estimated for Morocco indicate that between 2010 and 2030, the expected annual number of hip fractures would increase about twofold. INTRODUCTION: No data on hip fracture incidence trends exist from Africa. The aim of the study was to determine time trends in hip fracture rates for the province of Rabat and to forecast the number of hip fractures expected in Morocco up to 2030. METHODS: All hip fracture cases registered during the years 2006-2009 were collected at all the public hospitals and private clinics with a trauma unit and/or a permanent orthopedic surgeon across the province. RESULTS: Over the 4-year period, 723 (54.3%) hip fractures were recorded in women and 607 (45.6%) in men. The age- and gender-specific incidence of hip fracture rose steeply with advancing age. Hip fractures occurred later in women 75.0 (10.7) years than in men 73.3 (11.0) years (p=0.014), and its incidence was higher in women than in men [85.9 (95% CI 79.7-92.2) per 100,000 person-years vs. 72.7 (95% CI 66.9-78.5)]. The incidence remained globally stable over the period study, and the linear regression analysis showed no significant statistical difference. For the year 2010, there were 4,327 hip fractures estimated in Morocco (53.3% in women). Assuming no change in the age- and sex-specific incidence of hip fracture from 2010 to 2030, the number of hip fractures in men is expected to increase progressively from 2,019 to 3,961 and from 2,308 to 4,259 in women. CONCLUSION: The age-specific incidence of hip fracture between the years 2006 and 2009 remained stable in Morocco, and the number of expected hip fractures would double between 2010 and 2030.

Systematic vertebral fracture assessment in asymptomatic postmenopausal women.

INTRODUCTION: Recognition of vertebral fractures (VFs) changes the patient's diagnostic classification, estimation of fracture risk, and threshold for pharmacological intervention. Vertebral fracture assessment (VFA) enables the detection of VFs in the same session as bone mineral density (BMD) testing. OBJECTIVE: To study prevalence and risk factors of VFs using VFA in asymptomatic women and measure its effect on treatment recommendations. METHODS: We enrolled 908 postmenopausal women (mean age, weight and BMI of 60.9 ± 7.7 (50-91) years, 73.2 ± 13.2 (35-150) kg and 29.8 ± 5.3 (14.5-50.8) kg/m(2), respectively. Lateral VFA images and scans of the lumbar spine and proximal femur were obtained using a GE Healthcare Lunar Prodigy densitometer. VFs were defined using a combination of Genant semiquantitative (SQ) approach and morphometry. RESULTS: VFs were identified in 382 patients (42.0%): 203 (22.3%) had grade 1 and 179 (19.7%) had grade 2 or 3. The prevalence of VFA-detected fractures globally increased significantly with age and as BMI and BMD declined. A fracture was identified on VFA in 63 (28.3%) women with normal BMD (8.5% had grade 2/3 VFs) and in 145 (38.5%) with osteopenia (15.7% had grade 2/3 VFs). Stepwise regression analysis showed that presence of VFs was independently related to age, BMI, number of parity, history of peripheral fracture and lumbar spine BMD. CONCLUSION: A high proportion of women with asymptomatic VFs would not receive treatment if screening were based only on BMD evaluation. Our results support the recommendation to enlarge the indications of VFA in the presence of risk factors such as age over 60, multiparity, history of peripheral traumatic fractures and low BMI.

Vertebral fracture assessment in asymptomatic men and its impact on management.

INTRODUCTION: Recognition of vertebral fractures (VFs) change the patient's diagnostic classification, estimation of fracture risk, and threshold for pharmacological intervention. Vertebral fracture assessment (VFA) enables the detection of VFs in the same session as bone mineral density (BMD) testing. OBJECTIVE: To study prevalence and risk factors of VFs using VFA in asymptomatic men and measure its impact on patients' management. METHODS: We enrolled 791 men aged between 45 and 89 (mean age, weight and BMI of 62.4±8.6) (45 to 89) years, 74.9±12.7 (40 to 163) and 26.3±4.0 (16.6 to 43.8) kg/m(2), respectively. Lateral VFA images and scans of the lumbar spine and proximal femur were obtained using a GE Healthcare Lunar Prodigy densitometer. VFs were defined using a combination of Genant semiquantitative (SQ) approach and morphometry. RESULTS: VFs were identified in 318 (40.3%): 206 (26.0%) had grade 1 and 112 (14.2%) had grade 2 or 3. As would be expected, the prevalence of VFA-detected fractures globally increased significantly with age and as BMI and BMD declined. A fracture was identified on VFA in 85 (32.4%) of men with normal BMD (6.9% had grade 2/3 VFs) and in 144 (35.8%) with osteopenia (11.7% had grade 2/3 VFs). Stepwise regression analysis showed that presence of VFs was independently related to the osteoporotic status (OR=4.761, 95%CI [2.956-7.668]; p<0.0001) and current smoking (OR=1.717, 95%CI [1.268-2.323]; p=0.002). CONCLUSION: Our results support the recommendation to enlarge the indications of VFA to all the men referred for DXA measurement.

The role of torovirus in nosocomial viral gastroenteritis at a large tertiary pediatric centre.

OBJECTIVE: To describe the viral etiology and epidemiology of nosocomial viral gastroenteritis (NVG) at a tertiary care pediatric hospital and identify any changes over the past two decades. METHODS: Retrospective review of all patients with laboratory-confirmed NVG at The Hospital for Sick Children (Toronto, Ontario), from January 1, 2004, to December 31, 2005. RESULTS: One hundred forty-two episodes of NVG were found among 133 patients, occurring in 0.48 of 100 admissions. The median age was two years; 42% were <1 year of age and 41% were immunocompromised. The most commonly detected pathogen was torovirus (67% of episodes), followed by rotavirus (19%) and adenovirus (9%). Seventy-five cases (53%) were epidemiologically linked in 32 separate clusters (median cluster size two, range two to four). The NVG rate fell from 0.63 of 100 to 0.22 of 100 admissions after March 2005 (P<0.001) when enhanced infection control precautions were instituted in response to an outbreak of vancomycin-resistant Enterococcus. CONCLUSIONS: Torovirus remains the most commonly identified cause of NVG at The Hospital for Sick Children. Most NVG cases were epidemiologically linked, and a significant reduction in cases occurred after the institution of enhanced infection control practices following an outbreak of vancomycin-resistant Enterococcus. Improved education and surveillance for NVG should lead to further reduction in this problem.

HISTORIQUE: Les chercheurs ont effectué la présente étude pour décrire l'étiologie virale et l'épidémiologie de la gastroentérite virale nosocomiale (GVN) dans un hôpital de pédiatrie tertiaire et déterminer les changements constatés depuis vingt ans. MÉTHODOLOGIE: Analyse rétrospective de tous les patients ayant une GVN confirmée en laboratoire à The Hospital for Sick Children (HSC) de Toronto, en Ontario, entre le 1er janvier 2004 et le 31 décembre 2005. RÉSULTATS: Les chercheurs ont retracé 142 épisodes de GVN chez 133 patients, dans 0,48 pour 100 des admissions. Ils avaient un âge médian de deux ans, 42 % avaient moins d'un an et 41 % étaient immunocompromis. Le torovirus était le pathogène le plus décelé (67 % des épisodes), suivi du rotavirus (19 %) et de l'adénovirus (9 %). Soixante-quinze cas (53 %) étaient liés à 32 grappes distinctes (grappe médiane de deux, plage de deux à quatre) sur le plan épidémiologique. Le taux de GVN a fléchi de 0,63 à 0,22 pour 100 des admissions après le 5 mars 2005 (P<0,001), lorsqu'on a renforcé les précautions de contrôle des infections en réponse à une épidémie d'entérocoques résistant à la vancomycine (ERV). CONCLUSIONS: Le torovirus demeure la principale cause de GVN diagnostiquées à l'HSC. La plupart des cas de GVN étaient liés sur le plan épidémiologique, et on a constaté une importante diminution du nombre de cas après le renforcement des pratiques de contrôle des infections découlant d'une éclosion d'ERV. Une meilleure éducation et une plus grande surveillance à l'égard du GVN devraient favoriser l'atténuation plus marquée de ce problème.

Prevalence and risk factors of osteoporosis and vertebral fractures in patients with ankylosing spondylitis.

UNLABELLED: Ankylosing spondylitis (AS) is characterized by inflammation of the entheses and paravertebral structures, leading in time to bone formation at those sites. As well, vertebral bone loss is also a recognized feature of AS Objective: To calculate the prevalence and risk factors of osteoporosis and vertebral fractures in patients with AS. METHODS: Eighty patients with AS were enrolled in the study. Clinical, biological and radiological status was assessed by the Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), ESR and C-reactive protein (CRP), Bath AS Radiology Index (BASRI) and modified stoke AS spine score (mSASSS). BMD of the hip and spine was measured and vertebral fractures were defined using a combination of Genant semiquantitative (SQ) approach and morphometry by VFA (fracture vertebral assessment). RESULTS: The years+/-11.8. The mean BMI was 22.8 kg/m(2)+/-4.1 and the mean disease duration was 10.8 years+/-6.6. Prevalence of osteoporosis was 25%. 18.8% of patients had a vertebral fracture (grades 2 and 3). Factors associated with osteoporosis were low weight and BMI and longer disease duration, higher ESR, CRP, BASFI and BASDAI. Vertebral fractures were associated with advanced age, longer disease duration, higher BASFI, BASRI and mSASSS and reduced BMD and T-score at the hip site, presence of osteoporosis at any site. Multiple logistic regression analysis (Table 4) revealed that parameters significantly associated with osteoporosis were BASDAI (OR=1.05, 95% confidence interval [CI]: 1.03-1.09); disease duration (OR=1.13, 95%CI: 1.03-1.25); and BMI (OR=0.82, 95%CI: 0.69-0.93). The presence of VFs (grades 2 and 3) were independently associated with disease duration (OR=1.50, 95%CI: 1.07-2.10); and mSASSS (OR=1.17, 95%CI: 1.05-1.30). CONCLUSION: Osteoporosis is common in patients with AS and seems to be related to disease activity while vertebral fractures appear to be related to the duration and structural severity of the disease rather than BMD.
