Use of primary health care services and mortality in older patients with type 2 diabetes with or without comorbidities.

OBJECTIVE: This study aimed to examine primary health care (PHC) service utilization and mortality in older patients with type 2 diabetes (T2D) with or without comorbidities. DESIGN AND SETTING: A cohort study in PHC in the city of Vantaa, Finland. Follow-up period was set between the years 2011 and 2018. SUBJECTS: PHC patients aged 60 years or more with a T2D were included. MAIN OUTCOME MEASURES: Service utilization was defined as the number of face-to-face appointments and telephone contacts between a patient and general practitioner (GP) or nurse. The presence of comorbidities was defined using the Charlson Comorbidity Index (CCI). Mortality was assessed using hazard ratio (HR) and standardized mortality ratio (SMR). RESULTS: In total, 11,020 patients were included and followed for 71,596 person years. Mean age of the women and men in the beginning of follow-up were 71 and 69 years, respectively. The patients in the study cohort had a mean of eight appointments per person year to the GPs or nurses. Patients with T2D with comorbidities had more appointments than patients with T2D without comorbidities (incidence rate ratio (IRR) 1.44 [95% CI 1.39-1.49]). Increase in the number of all appointments reduced mortality in patients with T2D with and without comorbidities. Between patients with T2D with comorbidities and patients with T2D without comorbidities, the age and sex adjusted HR for death was 1.50 (95% CI 1.39-1.62). The SMR was higher in patients with T2D with comorbidities (1.83 [95% CI 1.74-1.92]) than in patients with T2D without comorbidities (0.91 [95% CI 0.86-0.96]). CONCLUSIONS: In older patients with T2D, the presence of comorbidities was associated with increased use of PHC services and increased mortality. Increase in the number of appointments was associated with reduced mortality in patients with T2D with or without comorbidities.Key PointsIn older patients with T2D, it has not been studied whether and to what extend multimorbidity affects use of PHC services and mortality.The presence of comorbidities according to the Charlson Comorbidity Index (CCI) was associated with increased use of PHC services.The number of appointments to GPs or nurses was associated with reduced mortality in patients with T2D with or without comorbidities according to the CCI.

Impact of maternal income on the risk of gestational diabetes mellitus in primiparous women.

AIMS: Findings concerning the impact of socio-economic status on the risk of gestational diabetes mellitus (GDM) are inconclusive and little is known about the simultaneous impact of income and educational attainment on the risk of GDM. This study aims to assess the impact of maternal prepregnancy income in combination with traditional GDM risk factors on the incidence of GDM in primiparous women. METHODS: This is an observational cohort study including 5962 Finnish women aged ≥ 20 years from the city of Vantaa, Finland, who delivered for the first time between 2009 and 2015, excluding women with pre-existing diabetes mellitus. The Finnish Medical Birth Register, Finnish Tax Administration, Statistics Finland, Social Insurance Institution of Finland and patient healthcare records provided data for the study. We divided the study population according to five maternal income levels and four educational attainment levels. RESULTS: Incidence of GDM decreased with increasing income level in primiparous women (P < 0.001 for linearity, adjusted for smoking, age, BMI and cohabiting status). In an adjusted two-way model, the relationship was significant for both income (P = 0.007) and education (P = 0.039), but there was no interaction between income and education (P = 0.52). CONCLUSIONS: There was an inverse relationship between both maternal prepregnancy taxable income and educational attainment, and the risk of GDM in primiparous Finnish women.

Short primiparous women are at an increased risk for gestational diabetes mellitus.

OBJECTIVES: Both short stature and adiposity are risk factors for gestational diabetes mellitus (GDM). The aim of this study was to simultaneously evaluate the importance of stature and degree of adiposity on development of GDM in primiparous women. STUDY DESIGN: Longitudinal cohort study. METHODS: In the city of Vantaa, Finland, between 2009 and 2015, all together 7750 primiparous women without previously diagnosed diabetes mellitus gave birth. Of these, 5223 women were ≥18 years of age with information on height, weight, and complete data from a 75 g 2-h oral glucose tolerance test composing the study participants of this study. RESULTS: A 155-cm tall woman with a body mass index (BMI) of 25.5 kg/m2 had a similar risk for GDM as a 175-cm tall woman with a BMI of 27.1 kg/m2. Women shorter than 159 cm had the highest prevalence of GDM, 28.7%, whereas women with height between 164 and 167 cm had the lowest prevalence of GDM, 19.9% (P < 0.001). Height was inversely and significantly associated with both 1- and 2-h glucose values (both P < 0.001). CONCLUSIONS: To avoid over diagnosis of GDM, an unbiased strategy is needed to determine and diagnose GDM in women with different stature and degree of adiposity.

Costs of diabetes medication among male former elite athletes in later life.

AIMS: Regular physical activity plays a major role, in both prevention and treatment of type 2 diabetes. Less is known whether vigorous physical activity during young adulthood is associated with costs of diabetes medication in later life. The aim of this study is to evaluate this question. METHODS: The study population consisted of 1314 former elite-class athletes and 860 matched controls. The former athletes were divided into three groups based on their active career sport: endurance, mixed and power sports. Information on purchases of diabetes medication between 1995 and 2009 was obtained from the drug purchase register of the Finnish Social Insurance Institution. RESULTS: The total cost of diabetes medication per person year was significantly lower among the former endurance (mean 81 € [95% CI 33-151 €]) and mixed group athletes (mean 272 € [95% CI 181-388 €]) compared with the controls (mean 376 € [95% CI 284-485 €]), (p < 0.001 and p = 0.045, respectively). Of the former endurance athletes, 0.4% used insulin, while 5.2% of the controls used insulin (p = 0.018). CONCLUSIONS: A career as former endurance, sprint, jumper or team game athlete seems to reduce the costs of diabetes medication in later life.

Mobility and muscle strength in male former elite endurance and power athletes aged 66-91 years.

The aim of this cross-sectional study was to compare mobility and muscle strength in male former elite endurance and power athletes aged 66-91 years (n = 150; 50 men in both former elite athlete groups and in their control group). Agility, dynamic balance, walking speed, chair stand, self-rated balance confidence (ABC-scale), jumping height, and handgrip strength were assessed. Former elite power athletes had better agility performance time than the controls (age- and body mass index, BMI-adjusted mean difference -3.6 s; 95% CI -6.3, -0.8). Adjustment for current leisure time physical activity (LTPA) and prevalence of diseases made this difference non-significant (P = 0.214). The subjects in the power sports group jumped higher than the men in the control group (age- and BMI-adjusted mean differences for vertical squat jump, VSJ 4.4 cm; 95% CI 2.0, 6.8; for countermovement jump, CMJ 4.0 cm; 95% CI 1.7, 6.4). Taking current LTPA and chronic diseases for adjusting process did not improve explorative power of the model. No significant differences between the groups were found in the performances evaluating dynamic balance, walking speed, chair stand, ABC-scale, or handgrip strength. In conclusion, power athletes among the aged former elite sportsmen had greater explosive force production in their lower extremities than the men in the control group.

Former male elite athletes have better metabolic health in late life than their controls.

Elite-class athletes have longer life expectancy and lower risk for chronic noncommunicable diseases possibly because of physically active and healthier lifestyle. In this study, we assessed former male Finnish elite-class athletes' (n = 392) and their matched controls' (n = 207) body composition, and risk for the metabolic syndrome (MS) and nonalcoholic fatty liver disease (NAFLD) in later life. Compared with the controls, the former athletes had lower body fat percentage (24.8% vs 26.0%, P = 0.021), lower risk for MS [odds ratio (OR) 0.57, 95% confidence interval (CI) 0.40-0.81], and NAFLD (OR 0.61, 95% CI 0.42-0.88). High volume of current leisure-time physical activity (LTPA) was associated with lower body fat percentage (P for trend < 0.001). When current volume of LTPA increased 1 MET h/week, the risk of MS and NAFLD decreased (OR 0.99, 95% CI 0.98-0.99 and OR 0.97, 95% CI 0.96-0.98, respectively). Although a career as an elite-class athlete during young adulthood may help to protect from developing metabolic syndrome, present exercise levels and volume of LTPA seem equally important as well.

Insulin therapy in the elderly with type 2 diabetes.

Type 2 diabetes (T2D) is a progressive disorder and therefore many elderly people with T2D will require insulin therapy in order to reach treatment targets and to optimize quality of life. It is commonly assumed that insulin is underutilized in elderly T2 diabetics because of fear that it is too complicated to use. With the use of long-acting insulin analogues it has become much easier to use insulin in elderly patients as once daily pen injections. When basal insulin treatment is initiated in T2D it is often added to the oral medication. The use of basal insulin analogues (e.g. detemir and glargine) with relatively little peaking effects has made insulin therapy in elderly subjects a relatively straightforward process. Newer insulin analogues are also discussed. The use of prandial insulin in addition to basal insulin and use of premixed insulin analogues is also discussed and illustrated with patient cases. Avoidance of hypoglycemia is an important factor to consider when choosing therapeutic agents for elderly T2D diabetics. This is certainly also true when establishing glycemic goals. Therefore insulin must be used with caution and wisely and the motto "start low and go slow" is a good principle. Basal insulin therapy in combination with oral drugs, most often metformin ­ is the most convenient initial regimen. However, all next steps, from one to two or even more daily injections in elderly T2D subjects should be considered carefully.

Detection of Streptococcus pneumoniae carriage by the Binax NOW test with nasal and nasopharyngeal swabs in young children.

The rapid detection of carriage of Streptococcus pneumoniae could assist in the management of pneumococcal infection, such as acute otitis media. We evaluated the reliability of the Binax NOW test in the exclusion and detection of pneumococcal carriage by nasal samples from 139 children and using nasopharyngeal samples from 250 children (aged 6-35 months) with respiratory infection with or without acute otitis media. The Binax NOW test results were compared with culture-based detection of carriage of S. pneumoniae. The Binax NOW test from the nasal samples had a sensitivity of 95%, a specificity of 78%, and the positive and negative predictive values were 83 and 93%, respectively; and for the nasopharyngeal samples the corresponding numbers were 88%, 95%, 96%, and 87%. When rapid knowledge of the carriage status of S. pneumoniae is needed, the Binax NOW test is a reliable method for the exclusion of carriage using nasal sampling, and in the detection of carriage using nasopharyngeal sampling.
