Does the duration of diabetes increase the risk of cancer? A nationwide population-based cohort of patients with new-onset diabetes and a matched reference cohort.

Diabetes mellitus and cancer are both common health issues, but the correlation between these two diseases remains unclear. We investigated the association of cumulative exposure of diabetes mellitus as an indication of hyperglycemia in terms of disease duration on multiple cancer types. We hypothesized that the risk of cancer would increase over time after the onset of diabetes. The study population consisted of a population-based cohort of 398,708 people and it was constructed from the Finnish CARING project. The Diabetes group consisted of 185,258 individuals, and the non-diabetic reference group comprised 187,921 individuals. Over 4.1 million person-years were accumulated, and the median follow-up time was 10.55 years. In the diabetes group, 25,899 cancer cases were observed compared with 23,900 cancers in the non-diabetic group. We did not find a clear relationship between the duration of diabetes mellitus and most cancer types examined. However, for cancers of the pancreas, prostate gland, bronchus, and lungs, a temporal relationship was found. Furthermore, even within the cancer types where the relationship was detected, it did not change over time. These findings indicate that diabetes does not independently increase the risk of cancer. Instead, the development of diabetes may be attributed to shared risk factors with cancer, such as obesity and/or insulin resistance accompanied by hyperinsulinemia. Thus, it is likely that the clock for increased cancer risk starts ticking already before onset of diabetes and hyperglycemia.

Renal Hyperfiltration as a New Mechanism of Smoking-Related Mortality.

INTRODUCTION: Renal hyperfiltration (RHF), an established risk factor for mortality, is prevalent among tobacco smokers. The aim of this study was to assess the mediating role of RHF in the association between smoking and mortality. AIMS AND METHODS: Data of this study were retrieved from the cohort of the Kuopio Ischemic Heart Disease Risk Factor Study (KIHD), including 2064 males from Finland. Study participants were followed over a 35-year period. Using classic and counterfactual mediation analysis approaches, we estimated the mediative effect of RHF in the association between smoking and each of the following outcomes: All-cause mortality, cardiovascular disease (CVD) mortality, and non-CVD mortality. RESULTS: The risk of all-cause mortality in smokers was twice that in nonsmokers (hazard ratio [HR], 2.06; 95% confidence interval [CI]: 1.84 to 2.31). Under the counterfactual framework the direct effect of smoking on all-cause mortality, controlled for RHF, corresponded to an HR of 2.00 (95% CI: 1.78 to 2.30). Of the effect of smoking on mortality, 5% (p-value = .016) was mediated by RHF. This finding concerned particularly non-CVD mortality. CONCLUSIONS: RHF mediated the effect of smoking on non-CVD and all-cause mortality, but not on CVD mortality. The generalizability of our study results is however limited by its focus on a Finnish male cohort, underscoring the need for further investigation into RHF's broader implications across diverse populations. IMPLICATIONS: This study elucidates the complex interplay between smoking, renal hyperfiltration (RHF), and mortality, offering novel insights into the mediating role of RHF. Our findings demonstrate that RHF significantly mediates the relationship between smoking and non-cardiovascular disease (non-CVD), but not CVD mortality. This distinction underscores the multifaceted role of RHF beyond its established association with cardiovascular events. By highlighting the specific pathways through which RHF mediates some of the smoking-attributed mortality, this research contributes to our understanding of the mechanisms linking smoking to mortality.

Empagliflozin is associated with lower cardiovascular risk compared with dipeptidyl peptidase-4 inhibitors in adults with and without cardiovascular disease: EMPagliflozin compaRative effectIveness and SafEty (EMPRISE) study results from Europe and Asia.

BACKGROUND: Studies that have reported lower risk for cardiovascular outcomes in users of Sodium-Glucose Cotransporter-2 Inhibitors (SGLT-2i) are limited by residual cofounding and lack of information on prior cardiovascular disease (CVD). This study compared risk of cardiovascular events in patients within routine care settings in Europe and Asia with type 2 diabetes (T2D) initiating empagliflozin compared to dipeptidyl peptidase-4 inhibitors (DPP-4i) stratified by pre-existing CVD and history of heart failure (HF). METHODS AND RESULTS: Adults initiating empagliflozin and DPP-4i in 2014-2018/19 from 11 countries in Europe and Asia were compared using propensity score matching and Cox proportional hazards regression to assess differences in rates of primary outcomes: hospitalisation for heart failure (HHF), myocardial infarction (MI), stroke; and secondary outcomes: cardiovascular mortality (CVM), coronary revascularisation procedure, composite outcome including HHF or CVM, and 3-point major adverse cardiovascular events (MACE: MI, stroke and CVM). Country-specific results were meta-analysed and pooled hazard ratios (HR) with 95% confidence intervals (CI) from random-effects models are presented. In total, 85,244 empagliflozin/DPP4i PS-matched patient pairs were included with overall mean follow-up of 0.7 years. Among those with pre-existing CVD, lower risk was observed for HHF (HR 0.74; 95% CI 0.64-0.86), CVM (HR 0.55; 95% CI 0.38-0.80), HHF or CVM (HR 0.57; 95% CI 0.48-0.67) and stroke (HR 0.79; 95% CI 0.67-0.94) in patients initiating empagliflozin vs DPP-4i. Similar patterns were observed among patients without pre-existing CVD and those with and without pre-existing HF. CONCLUSION: These results from diverse patient populations in routine care settings across Europe and Asia demonstrate that initiation of empagliflozin compared to DPP-4i results in favourable cardioprotective effects regardless of pre-existing CVD or HF status.

Synergic Interaction of Vitamin D Deficiency and Renal Hyperfiltration on Mortality in Middle-Aged Men.

OBJECTIVE: Vitamin D deficiency and renal hyperfiltration (RHF) are prevalent conditions both recently linked with mortality. The two conditions are interrelated, but their combined effect and interaction on mortality have not been studied. The objective of this study was to assess the combined effect and interaction of vitamin D deficiency and RHF on all-cause, cardiovascular (CV), and non-CV mortality in nondiabetic middle-aged men. METHODS: Middle-aged nondiabetic men (n = 1,959) were followed up for a median of 28 years. With adjustment for age, body mass index (BMI), smoking, BMI-smoking interaction, healthy Nordic diet (HND), alcohol consumption, and hypertension, we fitted Cox proportional hazard models to estimate the hazard ratios (HRs) of all-cause-, CV-, and non-CV mortality with respect to vitamin D deficiency and RHF. We evaluated the effect of interaction between RHF and vitamin D on the outcomes on the additive and multiplicative scales. RESULTS: Vitamin D deficiency and RHF, both individually and combined, are associated with a high hazard of mortality. The HRs for all-cause- and non-CV mortality were highest among men with coexisting vitamin D deficiency and RHF (HR, 3.02; 95% CI, 1.90 to 4.79; and HR, 3.63; 95% CI, 2.07 to 6.36; respectively). We found a synergic interaction between vitamin D deficiency and RHF in respect to all-cause (RERI, 1.47; 95% CI, 0.03 to 2.9) and non-CV mortality (RERI, 2.09; 95% CI, 0.02 to 4.16) of type positive multiplicative, positive additive. CONCLUSION: The synergic interaction of vitamin D deficiency and RHF on mortality might have importance in the global burden of the two conditions. Further studies investigating cause-specific mortality are needed to highlight underlying mechanisms by which vitamin D deficiency and RHF interact.

Negative interaction of fatty liver and hypertension on cardiovascular mortality in non-diabetic men: 34 years of follow-up.

BACKGROUND AND OBJECTIVES: Fatty liver disease (FLD) and hypertension are separately associated with cardiovascular (CV) mortality. The two conditions are related in multiple ways. This work aimed to study the joint effect and interaction of FLD and hypertension in respect to overall and CV mortality. METHODS: The population-based cohort, Kuopio Ischaemic Disease Risk Factor Study, followed 1569 middle-aged non-diabetic Finnish men for 34 years. Considering adjustment for age, body mass index, smoking and alcohol consumption, separate and combined effects of FLD and hypertension and their interaction at the multiplicative and additive scales regarding all-cause and CV death were assessed using Cox proportional hazards models. RESULTS: FLD and hypertension coexisted in 8.54% of the men (n = 134). FLD and hypertension associated, independently and combined, with an increased hazard of all-cause and CV deaths. Non-CV mortality associated with FLD, but not with hypertension. We found a negative interaction between FLD and hypertension regarding the hazard of all-cause (relative excess risk due to interaction (RERI), -0.97; 95% confidence interval (CI), -1.65 to -0.28) and CV mortality (RERI, -1.74; 95% CI, -2.98 to -0.5). The interaction was also found on a multiplicative scale. CONCLUSIONS: We found evidence of a negative interaction between FLD and hypertension in respect to CV mortality. We thus recommend adjusting for FLD or hypertension when studying the effect of the other condition on mortality or CV diseases in middle-aged men.

Follicle-Stimulating Hormone Levels and Subclinical Atherosclerosis in Older Postmenopausal Women.

Recent studies of perimenopausal women suggest that follicle-stimulating hormone (FSH) levels may be associated with atherosclerosis, independent of estradiol. Whether FSH is related to atherosclerosis in older postmenopausal women, who have completed the menopausal transition, remains unknown. We assessed the relationship of serum FSH and estradiol levels with carotid artery intima-media thickness (IMT) among 587 postmenopausal participants in the Kuopio Ischemic Heart Disease Risk Factor Study (Kuopio, Finland). Participants were aged 53-73 years and not using hormone therapy at baseline (1998-2001). Mean IMT was measured via high-resolution ultrasonography. We observed a significant inverse association between FSH levels and IMT. Mean IMTs among women in quartiles 1-4 of FSH were 0.94 mm, 0.91 mm, 0.87 mm, and 0.85 mm, respectively (P-trend < 0.001). After adjustment for age, estradiol, testosterone, body mass index (weight (kg)/height (m)2), lipids, and other factors, FSH levels remained significantly associated with IMT (regression coefficients for quartiles 2-4 vs. quartile 1 were -0.038, -0.045, and -0.062, respectively; P-trend = 0.01). Findings were strongest in women aged 64-73 years (P-trend = 0.006) and did not vary by body mass index. In contrast, estradiol levels were not related to IMT. In summary, high postmenopausal FSH levels were associated with a lower atherosclerotic burden, independent of estradiol, adiposity, and other factors. Our findings warrant replication and the further exploration of potential underlying mechanisms.

Risk of Cause-Specific Death in Individuals with Cancer-Modifying Role Diabetes, Statins and Metformin.

Both diabetes mellitus (DM) and cancer are common diseases and they frequently occur in the same patients. We investigated the all-cause and cause-specific mortality dynamics in relation to baseline DM, statin use and metformin use. The study population consisted of 39,900 incident cancer cases from Finland, 19,822 patients were free of DM at the start of follow-up and 20,078 had DM. Mortality from all causes, and cancer, cardiovascular (CVD) and other causes was analysed using Poisson regression model with the following variables: sex, age, DM, statin and metformin usage in baseline, cancer type and stage and calendar period. Statin usage was associated with a reduced cancer-specific mortality with incidence rate ratio (IRR) 0.72 (95% confidence interval 0.69-0.74), IRR for CVD mortality was 0.95 (0.88-1.02) and for other causes 0.64 (0.56-0.74). In a sub-population of DM patients, IRR for metformin in all-cause mortality was 0.74 (0.71-0.78), in cancer mortality 0.75 (0.72-0.79), in CVD mortality 0.75 (0.68-0.83) and other causes 0.68 (0.60-0.78). In conclusion, our register-based study of survival after cancer diagnosis showed that patients with diabetes had substantially poorer outcome in all measures. An association between baseline statin usage and lower all-cause, cancer and cardiovascular mortality was modified by cancer type. The effect of statin use was largest for breast and colorectal cancer. Metformin usage in a subpopulation of oral antidiabetic users was in general associated with lower mortality, but this association was modified by cancer type. The association was strongest for liver, colorectal and breast cancer.

A nationwide study on parathyroid carcinoma.

BACKGROUND: Parathyroid carcinoma (PC) is rare and diagnostically challenging. Reported outcomes are rather poor and the incidence might be increasing. MATERIAL AND METHODS: We performed a nationwide study on all cases (n= 32) diagnosed in 2000-2011 in Finland, and compared clinical and histopathological characteristics and outcome to atypical parathyroid (APA; n= 28) and parathyroid adenomas (PA; n= 72). The incidence in years 1955-1999 was compared to that in 2000-2013. RESULTS: Preoperatively, calcium and parathyroid hormone concentrations were higher in PC compared to APA and PA (1.76, 1.56 and 1.44 mmol/l, p < .001; and 989, 355 and 160 µmol/l, p < .001, respectively). Calcium was ≤1.77 mmol/l for all PAs. Hospitalization (44% vs. 22% and 3%, respectively, p = .01), renal (50% vs. 48% vs. 22%, respectively, p = .01) and bone (47% vs. 15% vs. 38%, respectively p = .002) manifestations were more common. PC and APA tumors were larger than PA (p < .001). Histopathological characteristics of PC compared to PA are increased mitotic activity (p= .001), chief cells (p = .003), diffuse growth pattern (p < .001), higher Ki67 (p< .001) and negative parafibromin (p < .001). One PC (1/18) and one APA (1/16) patient had a CDC73 mutation. After 6.7 (2-13.9) years of follow-up, 9.4% of PC had residual, 21% recurrent disease and 12.5% died of disease. Overall mortality did not differ between subgroups (p = .094). Recurrent PC was characterized by vascular invasion, lymph node metastases, high mitotic activity, necrosis and negative parafibromin. Incidence increased from 1.42 (range 0.52-2.14) to 7.14 (range 3.42-10.38)/10.000.000/years; (p < .001). CONCLUSIONS: PC associates with severe primary hyperparathyroidism and must be suspected if calcium ≥1.77 mmol/l. The prevalence of CDC73 germline mutations in PC and APA in Finland is 6%. PC has distinct histopathological characteristics and its incidence has increased over the past decades.

The Association Between Musculoskeletal Pain and Circulating Ornithine: A Population-Based Study.

Objective: Based on several previous clinical studies, we hypothesized that ornithine levels are different among subjects with persistent musculoskeletal pain compared with other subjects in the population. Design: The study sample consisted of 221 adults with nonpersistent pain, 76 with persistent pain, and 61 with no pain. Concentrations of glutamic acid, ornithine, citrulline, arginine, proline, and spermidine were analyzed using a mass spectrometer. Setting: Lapinlahti municipality in Finland. Results: For the subjects with no pain, nonpersistent pain, and persistent pain, the ornithine concentrations for men were 85.3 µmol/L (SD = 28.9 µmol/L), 98.9 µmol/L (SD = 37.8 µmol/L), and 102.1 µmol/L (SD = 37.1 µmol/L; P = 0.033), respectively. The corresponding concentrations for women were 82.8 µmol/L (SD = 25.2 µmol/L), 83.7 µmol/L (SD = 27.8 µmol/L), and 103.2 µmol/L (SD = 34.9 µmol/L; P = 0.0031). There were no significant differences between the pain groups for any of the other investigated amino acids. Relative sex-specific ornithine concentration adjusted for age, glomerular filtration rate, smoking, body mass index, physical activity, and depressive symptoms was associated with pain ( P = 0.025), the ornithine level being higher in the persistent pain group than in the no pain ( P = 0.006) and nonpersistent pain ( P = 0.032) groups. Conclusion: Ornithine levels are elevated in general population subjects with persistent pain.

Improved control of blood pressure and albuminuria among patients with type-2 diabetes in Finnish open care.

Risk of cardiovascular events within the diabetic population has decreased and survival increased with patients living longer and thus facing the development of end-stage renal disease (ESRD). This calls for good care of patient with diabetes with a focus on hypertension. Patient data were collected from 42 Finnish primary care centres. Each was asked to enrol 10-12 consecutive patients with type-2 diabetes between March 2011 and August 2012. Along with the office blood pressure measurements and laboratory tests, the presence of albuminuria was measured and glomerular filtration rate estimated (eGFR). The 2013 ESH criteria for diabetic hypertensive patients (<140/85 mmHg) was reached by 39% of all 625 study patients and 38% of the pharmacologically treated 520 patients. The absence of detectable albumin in urine was significantly associated with the control of systolic blood pressure and achievement of treatment goals. Beta blockers were the most common antihypertensive agents and patients treated with them had lower eGFR compared to those not treated with these agents. The blood pressure of patients was not in full concordance with the present guideline recommendations. However, satisfactory improvement in blood pressure control, reduction of albuminuria and hence ESRD prevention was achieved.

[Treatment of primary hypothyroidism in adult patients]. / Aikuisen primaarisen hypotyreoosin hoito.

The diagnosis of hypothyroidism is based on the findings of an increased serum TSH (above the reference range) and decreased serum free T4 (below the reference range) concentration. Treatment of subclinical hypothyroidism is indicated if serum THS is above 10 mU/l. For less severe forms of subclinical hypothyroidism, the treatment should be individually tailored. The treatment of choice is synthetic human levothyroxine. The goals for treatment are amelioration of symptoms and normalization of TSH and free T4 concentrations.

Cross-linking of sodium caseinate-structured emulsion with transglutaminase alters postprandial metabolic and appetite responses in healthy young individuals.

The physico-chemical and interfacial properties of fat emulsions influence lipid digestion and may affect postprandial responses. The aim of the present study was to determine the effects of the modification of the interfacial layer of a fat emulsion by cross-linking on postprandial metabolic and appetite responses. A total of fifteen healthy individuals (26.5 (sem 6.9) years and BMI 21.9 (sem 2.0) kg/m2) participated in a cross-over design experiment in which they consumed two isoenergetic (1924 kJ (460 kcal)) and isovolumic (250 g) emulsions stabilised with either sodium caseinate (Cas) or transglutaminase-cross-linked sodium caseinate (Cas-TG) in a randomised order. Blood samples were collected from the individuals at baseline and for 6 h postprandially for the determination of serum TAG and plasma NEFA, cholecystokinin (CCK), glucagon-like peptide 1 (GLP-1), glucose and insulin responses. Appetite was assessed using visual analogue scales. Postprandial TAG and NEFA responses and gastric emptying (GE) rates were comparable between the emulsions. CCK increased more after the ingestion of Cas-TG than after the ingestion of Cas (P< 0.05), while GLP-1 responses did not differ between the two test emulsions. Glucose and insulin profiles were lower after consuming Cas-TG than after consuming Cas (P< 0.05). The overall insulin, glucose and CCK responses, expressed as areas above/under the curve, did not differ significantly between the Cas and Cas-TG meal conditions. Satiety ratings were reduced and hunger, desire to eat and thirst ratings increased more after the ingestion of Cas-TG than after the ingestion of Cas (P< 0.05). The present results suggest that even a subtle structural modification of the interfacial layer of a fat emulsion can alter the early postprandial profiles of glucose, insulin, CCK, appetite and satiety through decreased protein digestion without affecting significantly on GE or overall lipid digestion.

Decreasing cholesterol levels in the community--lifestyle change with statin?

BACKGROUND: The Lapinlahti 2005-2010 study was carried out to explore cardiovascular disease risk factors and changes in lifestyle in Lapinlahti residents in eastern Finland. Our aim was to analyse factors influencing the level of cholesterol in the community. METHODS: In 2005, 480 subjects aged 30-65 years underwent a complete health survey (baseline study) that consisted of a structured questionnaire and a health examination. The follow-up was carried out five years later in 2010. The present study population included 326 individuals who did not use lipid-lowering medication at the baseline. A trained research nurse measured weight, height, waist circumference and blood pressure at the baseline and follow-up. Respectively, lifestyle factors (nutrition, exercise, smoking and alcohol use) were examined with a structured questionnaire. Each lifestyle item was valued as -1, 0 or 1, depending on how closely it fitted to the recommendations. Cholesterol level analyses at the baseline and follow-up were performed according to the protocol of the Kuopio University Hospital's medical laboratory. Based on their baseline cholesterol levels, the participants were divided into tertiles. The age- and sex-adjusted linear trend between the tertiles was tested. RESULTS: The change in cholesterol level was associated with lipid-lowering medication (P < 0.001). Lifestyle improvement was associated with the cholesterol level change but did not reach statistical significance (P = 0.061), although the interaction of lipid-lowering medication and lifestyle change was associated with the change in cholesterol level (P = 0.018). In multivariate analysis, a favourable change in fat consumption (P = 0.007) and lipid-lowering medication (P < 0.001) were associated with decreasing cholesterol levels. CONCLUSIONS: At the population level, dyslipidaemia is one of the most easily modifiable risk factors of CHD. Lipid-lowering medication may have the most significant impact on cholesterol level in communities with primary health care with good coverage. On the other hand, the potential of health-promoting and population-based prevention strategies may be underused.

Efficacy and safety of canagliflozin versus glimepiride in patients with type 2 diabetes inadequately controlled with metformin (CANTATA-SU): 52 week results from a randomised, double-blind, phase 3 non-inferiority trial.

BACKGROUND: Sodium-glucose cotransporter 2 (SGLT2) inhibitors improve glycaemia in patients with type 2 diabetes by enhancing urinary glucose excretion. We compared the efficacy and safety of canagliflozin, an SGLT2 inhibitor, with glimepiride in patients with type 2 diabetes inadequately controlled with metformin. METHODS: We undertook this 52 week, randomised, double-blind, active-controlled, phase 3 non-inferiority trial at 157 centres in 19 countries between Aug 28, 2009, and Dec 21, 2011. Patients aged 18-80 years with type 2 diabetes and glycated haemoglobin A1c (HbA1c) of 7·0-9·5% on stable metformin were randomly assigned (1:1:1) by computer-generated random sequence via an interactive voice or web response system to receive canagliflozin 100 mg or 300 mg, or glimepiride (up-titrated to 6 mg or 8 mg per day) orally once daily. Patients, study investigators, and local sponsor personnel were masked to treatment. The primary endpoint was change in HbA1c from baseline to week 52, with a non-inferiority margin of 0·3% for the comparison of each canagliflozin dose with glimepiride. If non-inferiority was shown, we assessed superiority on the basis of an upper bound of the 95% CI for the difference of each canagliflozin dose versus glimepiride of less than 0·0%. Analysis was done in a modified intention-to-treat population, including all randomised patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, number NCT00968812. FINDINGS: 1450 of 1452 randomised patients received at least one dose of glimepiride (n=482), canagliflozin 100 mg (n=483), or canagliflozin 300 mg (n=485). For lowering of HbA1c at 52 weeks, canagliflozin 100 mg was non-inferior to glimepiride (least-squares mean difference -0·01% [95% CI -0·11 to 0·09]), and canagliflozin 300 mg was superior to glimepiride (-0·12% [-0·22 to -0·02]). 39 (8%) patients had serious adverse events in the glimepiride group versus 24 (5%) in the canagliflozin 100 mg group and 26 (5%) in the 300 mg group. In the canagliflozin 100 mg and 300 mg groups versus the glimepiride group, we recorded a greater number of genital mycotic infections (women: 26 [11%] and 34 [14%] vs five [2%]; men: 17 [7%] and 20 [8%] vs three [1%]), urinary tract infections (31 [6%] for both canagliflozin doses vs 22 [5%]), and osmotic diuresis-related events (pollakiuria: 12 [3%] for both doses vs one [<1%]; polyuria: four [<1%] for both doses vs two [<1%]). INTERPRETATION: Canagliflozin provides greater HbA1c reduction than does glimepiride, and is well tolerated in patients with type 2 diabetes receiving metformin. These findings support the use of canagliflozin as a viable treatment option for patients who do not achieve sufficient glycaemic control with metformin therapy.

Reduced serum adiponectin levels in alexithymia.

OBJECTIVES: Clinical studies have demonstrated that circulating cytokine profiles may differ between alexithymic and non-alexithymic subjects. We examined whether the levels of adiponectin (µg/ml) and resistin (ng/ml) are independently related to alexithymic features in a population-based sample. METHODS: In 2005, clinical data including laboratory assessments were obtained from a sub-sample (n = 308) of the Kuopio Depression Study general population study including subjects aged 25-64 years. Based on the Toronto Alexithymia Scale score in 1998, 1999, 2001 and 2005, a group of subjects with high alexithymic features (n = 85) was formed and compared with non-alexithymic controls (n = 206). RESULTS: Serum adiponectin levels were significantly lower in subjects with alexithymic features than in non-alexithymic control subjects. No difference was found in resistin levels. Similarly, in a logistic regression model adjusted for age, gender and body mass index (BMI), lowered levels of adiponectin, but not resistin, were associated with an increased likelihood of belonging to the group with alexithymic features. Further adjustments for cardiovascular risk factors (i.e. smoking, BMI, metabolic syndrome, alcohol use, and coronary heart disease), depressive symptoms (Hamilton Depression Rating Scale with 17 items) and the use of antidepressants in addition to age and gender did not change these patterns. CONCLUSIONS: Our findings suggest that a disturbed anti-inflammatory balance may characterize alexithymia. In addition, our results widen the concept of alexithymia and highlight the role of immune system alterations and stress in alexithymic individuals.

Cross-sectional and longitudinal associations of circulating omega-3 and omega-6 fatty acids with lipoprotein particle concentrations and sizes: population-based cohort study with 6-year follow-up.

BACKGROUND: Cross-sectional studies have suggested that serum omega-3 (n-3) and omega-6 (n-6) polyunsaturated fatty acids (PUFAs) are related to favorable lipoprotein particle concentrations. We explored the associations of serum n-3 and n-6 PUFAs with lipoprotein particle concentrations and sizes in a general population cohort at baseline and after 6 years. FINDINGS: The cohort included 665 adults (274 men) with a 6-year follow-up. Nutritional counseling was given at baseline. Serum n-3 and n-6 PUFAs and lipoprotein particle concentrations and the mean particle sizes of VLDL, LDL, and HDL were quantified by nuclear magnetic resonance (NMR) spectroscopy for all baseline and follow-up samples at the same time. Concentrations of n-3 and n-6 PUFAs were expressed relative to total fatty acids. At baseline, n-3 PUFAs were not associated with lipoprotein particle concentrations. A weak negative association was observed for VLDL (P = 0.021) and positive for HDL (P = 0.011) particle size. n-6 PUFA was negatively associated with VLDL particle concentration and positively with LDL (P < 0.001) and HDL particle size (P < 0.001). The 6-year change in n-3 PUFA correlated positively with the change in particle size for HDL and LDL lipoproteins but negatively with VLDL particle size. An increase in 6-year levels of n-6 PUFAs was negatively correlated with the change in VLDL particle concentration and size, and positively with LDL particle size. CONCLUSION: Change in circulating levels of both n-3 and n-6 PUFAs, relative to total fatty acids, during 6 years of follow-up are associated with changes in lipoprotein particle size and concentrations at the population level.

Low quality of life and depressive symptoms are connected with an unhealthy lifestyle.

BACKGROUND: The Lapinlahti 2005 study was carried out to explore cardiovascular disease risk factors, lifestyle and quality of life in Lapinlahti residents in eastern Finland. Our aim was to study the association between lifestyle and health-related quality of life (HRQoL) in the community. SUBJECTS AND METHODS: The present study is based on the baseline data of the followed up (2005-2010) population-based cohort (N = 376, n of males = 184). A trained research nurse measured weight, height, waist circumference and blood pressure. Self-reported HRQoL was measured using a 15D questionnaire. A BDI-21 inventory was used to assess the presence of self-reported depressive symptoms. Lifestyle factors (nutrition, exercise, smoking and alcohol use) were examined with a structured questionnaire. Each lifestyle item was valued as -1, 0 or 1, depending on how well it corresponded to the recommendations. Based on the index the participants were divided into three lifestyle sum tertiles: I = unhealthy, II = neutral and III = healthy. The age- and sex-adjusted linear trend between the tertiles was tested. RESULTS: The 15D score had a positive linear relationship with the lifestyle tertiles (P = .0048 for linearity, age- and sex-adjusted). Respectively, self-reported depressive symptoms were less frequent among subjects with a healthier lifestyle (P = .038). CONCLUSIONS: People who are expected to strive most to change their lifestyle have the lowest quality of life and psychological welfare, which should be taken into account in both clinical work and health promotion.

Perceived sufficiency of physical activity levels among adults at high risk of type 2 diabetes: the FIN-D2D study.

BACKGROUND: Any increase from a low level of physical activity reduces the risk of type 2 diabetes. However, lack of awareness of one's physical activity level insufficiency may act as an obstacle to increased physical activity. PURPOSE: This study assessed the determinants of perceived physical activity levels (PALs) among adults at high risk of diabetes and the associations with self-reported physical activity. METHODS: In total, 10,149 adults participated in the FIN-D2D lifestyle intervention at baseline. Opportunistic screening was used in identifying high-risk individuals. Physical activity and perceived PAL sufficiency were assessed and compared. Key risk factors for diabetes and psychosocial and demographic characteristics were analyzed as determinants using logistic regression. RESULTS: PAL sufficiency was rated realistically by 73 % of men and 75 % of women. Perception of sufficient PAL was more likely among individuals with a smaller waist circumference, a higher level of perceived fitness, and no exercise intention. In men, a higher age, and in women, a lower education, and a lower occupational status, also increased the likelihood of perceiving PAL as sufficient. Out of all the participants, 65 % of men and 66 % of women were inactive. Among the inactive participants, 20 (men) and 16 % (women) overestimated their PAL sufficiency. In both genders, such overestimation was predicted by dyslipidemia, a lower waist circumference, a higher level of perceived fitness, and no exercise intention; also (among men) by a higher age and a family history of diabetes, and (among women) by a lower occupational status, and a lower BMI. CONCLUSIONS: In diabetes prevention, it is important to recognize the groups that perceive their PAL as sufficient since they may not see increased PAL as a tool for decreasing their risk of diabetes.

A pharmacoepidemiological nested case-control study of risk factors for venous thromboembolism with the focus on diabetes, cancer, socioeconomic group, medications, and comorbidities.

OBJECTIVES: A pharmacoepidemiological study to assess VTE risk factors in a diabetes-rich population. METHODS: The study comprised 299,590 individuals. We observed 3450 VTEs and matched them with 15,875 controls using a nested case-control approach and collected data on comorbidities and prescriptions. By multivariable conditional logistic regression, we calculated ORs with 95%CIs for comorbidities and medications to evaluate their associations with VTE. RESULTS: Diabetes (aOR 2.16; 95%CI 1.99-2.34), inflammatory bowel disease (1.84; 1.27-2.66), and severe psychiatric disorders (1.72; 1.43-2.05) had the strongest associations among the non-cancer comorbidities. Pancreatic (12.32; 7.11-21.36), stomach (8.57; 4.07-18.03), lung and bronchus (6.26; 4.16-9.43), and ovarian (6.72; 2.95-15.10) cancers were ranked as high-risk for VTE. Corticosteroids, gabapentinoids, psychotropic drugs, risedronic acid, and pramipexole were most strongly associated (aOR exceeding 1.5) with VTE. Insulin (3.86; 3.33-4.47) and sulphonylureas (2.62; 2.18-3.16) had stronger associations than metformin (1.65; 1.49-1.83). Statins and lercanidipine (0.78; 0.62-0.98) were associated with a lowered risk of VTE. CONCLUSIONS: In this cohort, with 50% diabetes prevalence, pancreatic, stomach, lung and bronchus, and ovarian cancers were strongly associated with VTE. Corticosteroids, gabapentinoids, and psychotropic medications had the strongest associations with VTE among medications. This may be valuable for generating hypotheses for the further research. Lercanidipine may be a novel protective medication against VTE.
