Risk factors of type 2 diabetes among Korean adults: The 2001 Korean national health and nutrition examination survey

This study aimed to identify risk factors for type 2 diabetes (T2D) in Korea, a rapidly changing country. Data of 5,132 adults aged 20-85 were used from the 2001 Korean Health and Nutrition Examination Survey. Multiple logistic regression was carried out to identify risk factors for T2D. Three models were specified: (i) socioeconomic and demographic factors (model 1: age, gender, education, poverty income ratio, employment), (ii) behavioral risk factors and covariates (model 2: obesity, physical activity, smoking, alcohol drinking, dietary quality, family history of T2D, co-morbidity) and (iii) socioeconomic, demographic, and behavioral factors (model 3). The prevalence of T2D was 7.4%. Less education (OR 1.41, 95% CI 1.08-1.84), age (OR 2.19, 95% CI 1.56-3.08 in 40-59 yrs, OR 4.05, 95% CI 2.76-5.95 in 60 yrs + comparing to 20-39 yrs) and abdominal obesity (OR 2.24, 95% CI 1.79-2.82) were risk factors for T2D even after controlling for other factors simultaneously. There was a significant association of T2D with ever smoking (OR 1.34, 95% CI 1.06-1.67). The relationship of age with T2D was modified by gender in model 1 and the relationship of smoking with T2D was modified by obesity in model 2. Less educated, older, obese or ever smokers were more likely to have T2D. Gender mediated the relationship of age, and obesity mediated the relationship of smoking, with T2D. Intervention programs for T2D in Korea should take the interactions among risk factors into account.     

Long-term improvement of metabolic control without increased risk of hypoglycaemia by intensive insulin regimens in type 1 diabetes patients treated in a regular clinical setting.

AIM: To evaluate if intensive insulin regimen with multiple daily injections (MDI) is successful for treating type 1 diabetes patients over a long period of time in a regular clinical setting. METHOD: This is a prospective, observational seven-year study. Fifty-nine (35 male) type 1 diabetic patients with bad metabolic control (HbA1c> or =9%), aged 31.9 years, range 18-47 were included in the present study. All of them had had at least 5 years of diabetes duration after diagnosis and showed negative responses of serum C-peptide to a standard breakfast. The main control variables are: Metabolic control measured by serum HbA1c values (values < 6.2 % was the treatment objective) and the frequency of hypoglycaemic episodes (episodes/patient-month). RESULTS: Significant decreases in mean+/-SD HbA1c values in this group of patients were observed from the first year of follow-up, with the mean values being: 7.5+/-1.5%, 7.2+/-1.8%, 7.6+/-1.6%, 7.1+/-1.7%, 7+/-1.4, 6.6+/-1.6% and 6.8+/-1.4% for the first, second, third, fourth, fifth, sixth and seventh years of follow-up respectively. Sixteen %, 27.5%, 15.7%, 33.3%, 28.6%, 42% and 33% of the patients reached the treatment objective (HbA1c values<6.2%) for each year of follow-up. Throughout the study period the rate of severe hypoglycaemia (episodes/patient-year) was 0.32+/-0.2 which was not significantly different compared with the value of 0.28+/-0.1 observed the year before the study began. Similarly frequencies of mild/moderate hypoglycaemia episodes (episodes/patient-month) varies between 16.5+/-4 and 21.7+/-5, which are not significantly different from the value of 17.7+/-6 observed the year before the study began. CONCLUSION: Long-term improvement in metabolic control was observed in this group of type 1 diabetes patients with previous bad control, during treatment in a regular clinical setting. A considerable percentage of type 1 diabetic patients with MDI reached the treatment objective in every year of follow-up. Furthermore improvement in metabolic control is not associated with significantly increased frequency of hypoglycaemia episodes.     

Cystic fibrosis mortality trends in France.

BACKGROUND: In 1992 France set up a national cystic fibrosis observatory (Observatoire national de la mucoviscidose, ONM) to monitor the state of health of patients on an annual basis. Using the ONM data, this study estimates the main indicators for life expectancy and assesses the total number of cystic fibrosis patients. METHODS: The data for the years 1994 to 2003 are divided into 3-year periods. Life tables are drawn up for these periods, from which mean and median lengths of life are determined. Using the most recent life table, the number of births in 2003 and the incidence of the disease, the total population of patients can be estimated, assuming a stationary population. RESULTS: In 2001-2003, life expectancy at birth of patients registered with the ONM was 39.1 years and median length of life was 36.4 years. These results, substantially better than those of 1994-1996, are linked to improved conditions of patient inclusion in the ONM database, to improvements in their healthcare, but also to the limitations of the life tables. Based on the 2003 data, the total theoretical number of patients is 6490, and coverage by the ONM database is thus 63.2%. CONCLUSIONS: These provisional results demonstrate the need to convert the ONM observatory into a registry providing exhaustive coverage of all patients.     

Utility of the sural fasciocutaneous flap for the treatment of chronic osteomyelitis of the distal tibia

Treatment of chronic osteomyelitis of distal tibia is complex. It often requires the association of antibiotic therapy and a surgical procedure. This consists of exhaustive debridement of infected bone and soft tissue which must have adequate cutaneous coverage and vascular supply which enables creating a barrier to microorganisms and greater resistance to infection. Free or pedicled muscular flaps have been the techniques most often used for this type of lesions. Free flaps require a precise microsurgical technique and prolonged surgery. Pedicled muscular flaps do not provide sufficient coverage and vascularisation of the distal tibia for large size defects. The fasciocutaneous flap has been used for the treatment of coverage defects in the perimalleolar area and the heel. We report the utility of this flap as management of chronic osteomyelitis of the distal third of the tibia with complete healing of the infection and correct cutaneous coverage without complications.     

Characteristics of apathy in Parkinson's disease.

The objective of this study was to use the Lille Apathy Rating Scale to assess apathy in a large population of Parkinson's disease (PD) patients and identify several different apathy profiles. One hundred fifty-nine patients with probable PD and 58 healthy controls participated in the study. Apathy was assessed using the Lille Apathy Rating Scale. Motor, cognitive, and depressive symptoms were rated on standardized scales. Data were analyzed using linear regression and multivariate analyses of variance. Thirty-two percent of the PD patients were classified as apathetic. Apathy was more frequent in patients with dementia. The four apathy dimensions contributed differently to the overall severity of the apathetic condition. Action initiation and intellectual curiosity had a marked influence. Linear regression analysis revealed that the apathy level was mainly determined by cognitive impairment, not associated with the severity of motor symptoms, and only associated with the apathy subcomponent of the Montgomery and Asberg Depression Rating Scale. Apathy is highly prevalent in PD patients. Apathy profiles vary according to the clinical presentation of PD. The high prevalence of apathy in PD suggests the involvement of frontal-subcortical circuits. Although the neurochemical substrate of apathy remains poorly characterized, the strong link between apathy and cognitive impairment observed in several studies suggests the participation of nondopaminergic circuits.
