Background: Long-term associations between type 2 diabetes, prediabetes, and muscle strength are obscure in older adults. The aim of this study was to examine type 2 diabetes as a predictor of handgrip strength decline during an 11-year follow-up among men and women aged 55 years. Methods: We used Finnish population-based Health 2000 Survey and its follow-up measurements in 2011. The study population consisted of 1,200 individuals, aged 55–86 years at baseline. Baseline fasting glucose level or use of diabetes medication was used to categorize the participants into diabetes (≥7.0 mmol/L), prediabetes (≥6.1 mmol/L but Results: Mean handgrip strength at baseline did not differ between diabetes groups in men or women. Among men during the 11-year follow-up, decline in muscle strength was significantly greater among diabetes group (−131.5 Newtons [N], 95% confidence interval (CI) −182.7 to −80.4) than nondiabetes group (−98.9 N, 95% CI −139.5 to −58.3) after adjusting for age, education, lifestyle factors, chronic conditions, and diabetes status at follow-up. Among women, muscle strength decline did not differ between diabetes, prediabetes, or nondiabetes groups after adjusting for all potential covariates, the results being −45.0 N (95% CI −73.2 to −16.7), −29.4 N (95% CI −59.7 to 0.9), and −42.3 N (95% CI −70.5 to −14.1), respectively. Conclusions: The presence of type 2 diabetes was associated with greater muscle strength decline among older men but not among older women.

The aim of this study was to evaluate the effects of deep brain stimulation of the anterior nucleus of the thalamus (ANT-DBS) on systemic inflammatory responses in patients with drug-resistant epilepsy (DRE). Twenty-two Finnish patients with ANT-DBS implantation were enrolled in this pilot study. Changes in plasma interleukin-6 (IL-6) and interleukin-10 (IL-10) levels were examined using generalized estimating equation models at seven time points (before DBS surgery and 1, 2, 3, 6, 9 and 12 months after implantation). In the whole group, the IL-6/IL-10 ratio decreased significantly over time following ANT-DBS, while the decrease in IL-6 levels and increase in IL-10 levels were not significant. In the responder and nonresponder groups, IL-6 levels remained unchanged during the follow-up. Responders had significantly lower pre-DBS IL-10 levels before the ANT-DBS treatment than nonresponders, but the levels significantly increased over time after the treatment. In addition, responders had a higher pre-DBS IL-6/IL-10 ratio than nonresponders, and the ratio decreased for both groups after treatment, but the decrease did not reach the level of statistical significance. The rate of decrease in the ratio per month tended to be higher in responders than in nonresponders. These results may highlight the anti-inflammatory properties of ANT-DBS treatment associated with its therapeutic effectiveness in patients with DRE. Additional studies are essential to evaluate the potential of the proinflammatory cytokine IL-6, the anti-inflammatory cytokine IL-10, and their ratio as biomarkers to evaluate the therapeutic response to DBS treatment, which could facilitate treatment optimization.

OBJECTIVES: To investigate the interaction among the efficacy, tolerability and overall effectiveness of the first antiseizure medication in patients 16 years or older with newly diagnosed epilepsy. MATERIALS AND METHODS: The study included 584 patients who were referred to the Tampere University Hospital between 1 January 1995 and 31 December 2005 and were diagnosed with epilepsy. All individuals were retrospectively followed up until 31 December 2006, until reaching at least one year of seizure freedom, or until death if before the cut-off date. RESULTS: Overall, after thorough validation of the epilepsy diagnosis 459 patients comprised the study cohort; among these patients, 73% of males and 60% of females became seizure-free for at least one year with the first antiseizure medication. The seizure freedom rate for focal epilepsy was 67%. There was no significant difference in focal epilepsy to achieve seizure freedom between oxcarbazepine, carbamazepine or valproic acid. The seizure freedom rate among patients above 60 years of age was 67%. For patients with structural and unknown aetiology, seizure freedom rates were 61.5% and 75.3%, respectively. Additionally, epileptiform activity on EEG in patients with focal epilepsy decreased odds of seizure freedom in adjusted logistic regression models (OR 0.55, p=0.036). CONCLUSIONS: This study provides a more positive prediction of seizure freedom compared with previous studies with the onset of epilepsy at 16 years or older with an overall estimation that two-thirds of patients with new-onset epilepsy obtain seizure freedom with the first antiseizure medication. acceptedVersion

Exercises on a music mat were developed to promote Finnish, 4-6-year-old children’s and their parents’ physical activity (PA) and decrease sedentary behavior (SB) in the home environment. Altogether, fifteen families performed eight-week exercise intervention using a music mat. SB and PA were assessed by a tri-axial hip-worn accelerometer, and further by exercise diaries and questionnaires. The statistical methods employed a linear mixed-effects model design. Regarding children (n=14) and mothers (n=14), any statistically significant differences in the primary outcomes over time were not found. Among fathers (n=8), in turn, the reduction of SB was statistically significant (p=0.031). Most of the children and all the parents used the music mat less than instructed. The association between the children and their parents was negligible in all device-measured outcomes. One-third of children who used the music mat regularly as instructed increased their moderate-to-vigorous PA and Total-PA and decreased their SB. In conclusion, the music mat exercises in the home environment may promote PA or reduce SB among those who are willing to use the music mat regularly. At least, exercises might be a good addition to weekly PA and to break long sedentary bouts.

BACKGROUND The European Randomized Study of Screening for Prostate Cancer has shown a 20% reduction in prostate cancer (PC) mortality by prostate-specific antigen-based screening. In addition, screening has been shown to reduce the risk of advanced PC. The objective of the current study was to analyze the impact of screening participation on the incidence of PC by risk group. METHODS The participants in the screening arm of the Finnish trial (31,867 men) were classified according to screening attendance in a time-dependent fashion. Initially, all men in the screening arm were regarded as nonattenders until the first screening attendance; they then remained in the once-screened group until the second screen and similarly for the possible third round. The control arm formed the reference group. Follow-up started at randomization and ended at the time of diagnosis of PC, emigration, or the end of 2015. PC cases were divided into risk groups according to European Association of Urology definitions. RESULTS The incidence of low-risk PC increased with the number of screens, whereas no clear relation with participation was noted in the intermediate-risk and high-risk cases. For patients with advanced PC, attending screening at least twice was associated with a lower risk. CONCLUSIONS Screening reduces the risk of advanced PC after only 2 screening cycles. A single screen demonstrated no benefit in terms of PC incidence. Repeated screening is necessary to achieve screening advantages.

Aims: This study aimed to find out how place of death varied between countries with different health and social service systems. This was done by investigating typical groups (concerning age, sex and end-of-life trajectory) of older people dying in different places in Finland and Norway. Methods: The data were derived from national registers. All those who died in Finland or Norway at the age of ⩾70 years in 2011 were included. Place of death was analysed by age, sex, end-of-life trajectory and degree of urbanisation of the municipality of residence. Two-proportion z-tests were performed to test the differences between the countries. Multinomial logistic regression analyses were performed separately for both countries to find the factors associated with place of death. Results: The data consisted of 68,433 individuals. Deaths occurred most commonly in health centres in Finland and in nursing homes in Norway. Deaths in hospital were more common in Norway than they were in Finland. In both countries, deaths in hospital were more common among younger people and men. Deaths in nursing homes were commonest among frail older people, while most of those who had a terminal illness died in health centres in Finland and in nursing homes in Norway. Conclusions: Both Finland and Norway have a relatively low share of hospital deaths among older people. Both countries have developed alternatives to end-of-life care in hospital, allowing for spending the last days or weeks of life closer to home. In Finland, health centres play a key role in end-of-life care, while in Norway nursing homes serve this role.

BackgroundIncreasing evidence supports the role of soluble inflammatory mediators in the pathogenesis of refractory temporal lobe epilepsy (TLE). Hippocampal sclerosis (HS) is a well-described pathohistological abnormality in TLE. The association of proinflammatory cytokines with epileptic disease profiles is well established; however, the potential significance of circulating interleukin 10 (IL-10), particularly in TLE-associated HS, is still poorly understood. Therefore, taking into consideration the neuroprotective and anticonvulsive effects of IL-10, we performed this study to examine the role of the plasma levels of IL-10 in patients with TLE with HS (TLE + HS), TLE without HS (TLE-HS) and with other types of epilepsy.MethodsThis study included 270 patients with refractory epilepsy who were classified into four groups: i) 34 patients with TLE + HS, ii) 105 patients with TLE-HS, iii) 95 patients with extra-TLE (XLE) and iv) 36 patients with idiopathic generalized epilepsy (IGE). The plasma IL-10 levels were quantified using a commercially available enzyme-linked immunosorbent assay (ELISA).ResultsIL-10 levels were significantly lower in TLE + HS than in TLE-HS (p = 0.013). In a subgroup of TLE-HS patients who had seizures 1 month before sampling, patients with seizures had significantly higher IL-10 levels than patients who were seizure-free (p = 0.039). Among a small group (n = 15) of non-refractory TLE-HS patients, IL-10 levels showed a moderate negative correlation with the duration of epilepsy (r = − 0.585,p = 0.023).ConclusionsThis study demonstrated that chronically reduced levels of plasma IL-10 were associated with HS in TLE patients, suggesting that there was an inadequate systemic anti-inflammatory immune response. These results could provide new biological insights into the pathophysiology of HS in TLE. We also found that the production of IL-10 could be affected by the seizure frequency and declined concomitantly with increased disease durations. Therefore, the measurement of plasma IL-10 may have diagnostic value as a biomarker for stratifying TLE + HS from other epilepsy types or as a marker of disease progression towards a progressive form of epilepsy.

Background In prostate cancer (PCa), lower education level is associated with less screening, more advanced stage at diagnosis and worse survival. The aim of this study was to estimate the association between education level and treatment modality and subsequently survival. Methods The 9255 men diagnosed with PCa in the Finnish Randomized Study of Screening for Prostate Cancer were included. Cancer stage, comorbidity, education level and primary treatment modality were extracted from the patient records, the Finnish Cancer Registry, Statistics Finland and the National Institute of Health and Welfare, and these covariates were used in logistic regression (treatment selection) and Cox regression (survival analysis). Results In high-risk cancers, men with tertiary education were more likely to be treated with radical prostatectomy (odds ratio [OR] = 1.76; 95% confidence interval [CI] = 1.27–2.44) than men with primary education. Men with secondary (OR = 0.57; 95% CI = 0.38–0.84) or tertiary (OR = 0.42; 95% CI = 0.29–0.60) education were managed less frequently with mere hormonal therapy. In locally advanced cases, tertiary education was associated with more curatively aimed therapies and less hormonal therapy (OR for radical prostatectomy = 2.34; 95% CI = 1.49–3.66; OR for radiotherapy = 1.42; 95% CI = 1.09–1.85; OR for hormonal therapy = 0.45; 95% CI = 0.33–0.60). The hazard ratio for PCa death was lower in men with secondary (0.81; 95% CI = 0.69–0.95) and tertiary (0.75; 95% CI = 0.65–0.87) education than in the patients with primary education. Conclusions When controlled for the cancer risk group, comorbidity and patient's age, low education level is independently associated with less curatively aimed treatment in men with high-risk or locally advanced PCa and subsequently worse prognosis.

Pihlainen, K, Kyröläinen, H, Santtila, M, Ojanen, T, Raitanen, J, and Häkkinen, K. Effects of combined strength and endurance training on body composition, physical fitness, and serum hormones during a 6-month crisis management operation. J Strength Cond Res XX(X): 000-000, 2020-Very few studies have examined the impact of training interventions on soldier readiness during an international military operation. Therefore, the present study investigated the effects of combined strength and endurance training on body composition, physical performance, and hormonal status during a 6-month international military deployment consisting of typical peacekeeping tasks, e.g., patrolling, observation, and on-base duties. Soldiers (n = 78) were randomly allocated to a control group (C) or one of 3 combined whole-body strength and endurance training groups with varying strength-to-endurance training emphasis (Es = 25/75%, SE = 50/50% or Se = 75/25% of strength/endurance training). Body composition, physical performance (3000-m run, standing long jump [SLJ], isometric maximal voluntary contraction of the lower [MVC lower] and upper extremities [MVC upper ], muscle endurance tests), and selected serum hormone concentrations were determined prior to training (PRE), and after 9 (MID) and 19 (POST) weeks of training. Within- and between-group changes were analyzed using linear regression models. The average combined strength and endurance training frequency of the total subject group was 3 ± 2 training sessions per week. No changes were observed in physical performance variables in the intervention groups, whereas SLJ decreased by 1.9% in C (p < 0.05). Maximal voluntary contraction lower increased by 12.8% in the combined intervention group (p < 0.05), and this was significantly different to C (p < 0.05). Testosterone-to-cortisol ratio increased in SE and Se (p < 0.05), whereas no change was observed in C. The intervention groups maintained or improved their physical performance during deployment, which is beneficial for operational readiness. However, the high interindividual variation observed in training adaptations highlights the importance of training individualization during prolonged military operations. publishedVersion

Importance: Prostate-specific antigen (PSA) screening for prostate cancer has resulted in a slight reduction in prostate cancer mortality but also a concomitant overdiagnosis of low-risk tumors. Prostate-specific antigen levels are affected by use of cholesterol-lowering statin drugs, but the association of statin use with PSA screening performance is unknown. Objective: To investigate whether statin use was associated with outcomes of a randomized PSA-based prostate cancer screening intervention. Design, setting, and participants: This post hoc subgroup analysis of a cohort from a population-based randomized clinical trial used data from the population-based Finnish Randomized Study of Prostate Cancer Screening, which randomized men to PSA screening or routine care from March 1, 1996, to December 31, 1999, with follow-up continuing until December 31, 2015. The population included all men aged 55 to 67 years at baseline and residing in the Tampere or Helsinki districts of Finland. Information on statin purchases from 1996 to 2009 was obtained from a national prescription registry. Eligible men were identified from the population registry of Finland. Prevalent prostate cancer cases at baseline were excluded. Data were analyzed from January 1, 2019 to March 31, 2021. Interventions: Three invitations for PSA screening at 4-year intervals from 1996 to 2007 vs routine care. Main outcomes and measures: Risk for prostate cancer overall, high-risk disease, and prostate cancer mortality in the screening group vs the control group as an intention-to-treat analysis. The analysis was stratified by statin use. Results: The study comprised 78 606 men (median age, 59 years [range, 55-67 years]) with statin purchase data available. Although PSA screening was associated with increased prostate cancer incidence among statin nonusers (screening vs control, 11.2 vs 8.6 per 1000 person-years); rate ratio [RR], 1.31; 95% CI, 1.24-1.38), no similar increase in incidence was observed among statin users (6.9 vs 5.9 per 1000 person-years; RR, 1.02; 95% CI, 0.95-1.10; P < .001 for interaction). Incidence of low-risk (Gleason score 6) and localized tumors was lower among statin users, whereas detection of tumors with a Gleason score of 8 to 10 was similar. Screening was associated with a lower incidence of metastatic tumors regardless of statin use. Conclusion and relevance: In this post hoc subgroup analysis of a cohort from a population-based randomized clinical trial, PSA screening among statin users was associated with a decreased incidence of advanced prostate cancer that was similar among statin nonusers, but with less increase in detection of low-grade localized tumors in statin users than in nonusers. These findings suggest that statin use does not materially compromise benefits of PSA-based screening. acceptedVersion

Background Comorbidities have major implications for the care of people with dementia. Aim To investigate the patterns of comorbidities in dementia in the last five years of life and how these patterns differed between three cohorts. Methods The study included people who died at age 70 and above in 2001 (n = 13,717), 2007 (n = 34,750) and 2013 (n = 38,087) in Finland. ICD-10 morbidity data for a five-year period prior to death were extracted from national registers. Principal component analysis was employed to identify patterns for several morbidities. The associations of principal component scores with dementia were analysed using binary logistic regression. Linear regression was used to examine changes in the number of morbidities in patterns over time. Results The morbidity patterns identified in the last years of life were (1) cardiometabolic disorders, (2) neurological, (3) cerebrovascular diseases and (4) musculoskeletal, thyroid and psychiatric disorders. Among the patterns, neurological and musculoskeletal, thyroid and psychiatric disorders were associated with dementia. The number of diagnoses in the cerebrovascular pattern increased and those in the musculoskeletal, thyroid and psychiatric pattern decreased over time. Discussion Comorbidity patterns identified in this nationwide register study are largely in line with previous evidence. Time difference in these patterns provide crucial information for service planning. Conclusions Comorbidities in dementia in the last years of life occur in patterns and change over time. More systematic monitoring and updated clinical guidelines are needed for the care of comorbidities with dementia.

OBJECTIVE: To evaluate digital rectal examination (DRE) as a predictor of prostate cancer (PC) at serum PSA level 3.0-3.9 ng/ml. We compared the PC incidence rates of men with different screening test results in this PSA range and analyzed DRE in comparison with free/total PSA ratio as an additional screening test. MATERIALS AND METHODS: Using data from the FinRSPC trial, PC incidence rate ratios (IRR) for groups defined by the secondary screening test results (DRE vs. free/total PSA) were calculated for 17-year follow-up, using adjustment for age, family history of PC and place of residence. Screening test performance was evaluated by calculating sensitivity, specificity, positive and negative predictive value, and likelihood ratio. RESULTS: The IRR for men with a positive DRE compared to those with a negative result was 1.40 (95% confidence interval (CI) 1.00-1.96), while the IRR for men with a positive free/total PSA result compared to those with a negative one was 1.62 (95% CI 1.08-2.43). The estimated sensitivity was 0.15 (95% CI 0.11-0.20, 40/270) for DRE and 0.32 (95% CI 0.23-0.41, 36/113) for free/total PSA, and the specificity 0.91 (95% CI 0.88-0.93, 419/461) for DRE and 0.85 (95% CI 0.78-0.90, 134/158) for free/total PSA. CONCLUSIONS: Our results do not support utility of DRE as a screening test for PC at serum PSA level 3.0-3.9 ng/ml, while the results regarding free/total PSA determination were more encouraging and reconfirm the decision to switch from DRE to free/total PSA. publishedVersion

While it is known that those who are living their last years are frequent users of social and health services, research about medicines at the end of life is scarce. We examined whether the proportions of purchasers and the types of prescription medicines purchased during a 2-year period differed between community-dwelling old people who died (decedents) in 2002, 2006 or 2011 and old people who lived at least 2 years longer (survivors) in Finland. We also examined how those differences changed over time. The study population was identified from nationwide registers and consisted of 174,097 community-dwelling people who were 70 years of age or older. Of these, 81,893 were decedents and 92,204 survivors. Data on purchases of medicines were gathered from the Finnish prescription database. Along with descriptive analyses, binary logistic regression analysis was used to find the association between decedent status and the purchase of medicines in general and different categories of medicines in particular. Almost all community-dwelling decedents and survivors purchased medicines at least once during the 2-year period. Over time, the proportion of purchasers increased in both groups but especially among survivors, thereby reducing the differences between the groups. However, the probability of purchasing medicines in general and different categories of medicine in particular remained significantly higher for decedents than for survivors after adjustments. This study shows that purchases of medication are concentrated at the end of life, as is the use of social and health services. However, the differences between decedents and survivors diminish over time.

Background/Aim: This is a report of the 5-year quality of life (QoL) findings of the BREX-study (n=444). Patients and Methods: A 12-month exercise intervention was arranged shortly after adjuvant treatments. Physical activity (PA) was assessed by PA diary, physical performance by a 2- km walking test, QoL by the EORTC QLQC30 and BR-23 questionnaires, fatigue by the FACIT-Fatigue scale and depression by the Beck’s 13-item depression scale (BDI). Results: Participants who improved their PA from baseline to 5-year follow-up were more likely to improve their global health score (RRR=1.02, p=0.016), physical (RRR=1.02, p=0.009), social (RRR=1.03, p=0.013), role functioning (RRR=1.03, p=0.005), and fatigue (RRR=1.02, p=0.002). An improved 2-km walking test was associated to improved global health, physical and role functioning, body image, future perspectives, and fatigue (p=0.011, p

Moving to music combines the ability of rhythm and coordination. In relation to the musical and motor development of children, sensorimotor synchronization requires the ability to perceive and perform a steady beat. The present pilot study aimed to investigate the test–retest repeatability of a rhythm coordination test procedure in order to pilot the procedure for children. Test–retest repeatability reflects the variation in measurements taken by the rhythm coordination test on the same participant under the same conditions. Ten children (mean age 5.5 years, standard deviation (SD) 0.6) participated in the tests. The test performance was evaluated in points from 0 to 8, separately at a slow and fast pace, resulting in 16 points altogether. Test sessions were performed twice for each child within a four-day interval. Children reached, on average, 7.8 (SD 3.5) points in the first and 8.1 (SD 3.6) points out of 16 in the second test session. The test–retest mean intra class correlation was 0.96, indicating a high repeatability of the rhythm coordination test for children. Further, the children older than 5.5 years achieved a higher number of points than the younger ones, and they seemed to reach almost the same level as adults. The rhythm coordination test procedure for children provides a promising means of assessing children’s sensorimotor synchronization in the context of movement and music. publishedVersion

Longitudinal studies examining changes in physical functioning with advancing age among very old people are plagued by high death rates, which can lead to biased estimates. This study was conducted to analyse changes in physical functioning among the oldest old with three distinct methods which differ in how they handle dropout due to death. The sample consisted of 3992 persons aged 90 or over in the Vitality 90+ Study who were followed up on average for 2.5 years (range 0–13 years). A generalized estimating equation (GEE) with independent ‘working’ correlation, a linear mixed-effects (LME) model and a joint model consisting of longitudinal and survival submodels were used to estimate the effect of age on physical functioning over 13 years of follow-up. We observed significant age-related decline in physical functioning, which furthermore accelerated significantly with age. The average rate of decline differed markedly between the models: the GEE-based estimate for linear decline among survivors was about one-third of the average individual decline in the joint model and half the decline indicated by the LME model. In conclusion, the three methods yield substantially different views on decline in physical functioning: the GEE model may be useful for considering the effect of intervention measures on the outcome among living people, whereas the LME model is biased regarding studying outcomes associated with death. The joint model may be valuable for predicting the future characteristics of the oldest old and planning elderly care as life expectancy continues gradually to rise.

Background Physical activity (PA) is known to be associated with lipid profiles and the risk of both cardiovascular diseases and cancer. The aim of this study was to evaluate the association of objectively measured PA, sedentary behaviour (SB), amount of breaks during SB and number of daily steps with serum lipids in a healthy, Finnish, middle-aged, female population. Methods The participants (571) were recruited at mammography screening, target group was women aged 50–60 years. A measurement of PA was done with accelerometer, blood lipid profile was assessed, and questionnaires of participants characteristics were sent to participants. Results The participants with the highest number of daily breaks during SB (≥ 41) had the highest mean concentration of HDL-cholesterol (high density lipoprotein cholesterol, HDL-c) (1.9 mmol/l, standard deviation (SD) 0.4) and the lowest mean concentration of triglycerides (1.0 mmol/l, SD 0.5). HDL-c level was 0.16 mmol/l higher (p p Those with the most daily steps (≥ 9100) had the highest mean HDL-c level (1.9 mmol/l). HDL-c level was 0.16 mmol/l higher (p p From wake-time, participants spent 60% in SB, 18% standing, 14% in light PA, and 9% in moderate-to-vigorous PA (MVPA). PA was associated with serum total cholesterol (TC), HDL-c and triglyceride levels. The mean HDL-c level was the highest in the lowest quartile of SB and in the highest quartile of MVPA. Conclusions To our knowledge, this is the first study showing a high number of objectively measured breaks during SB is associated with a favourable effect on the level of serum lipids, which may later translate into cardiovascular health among middle-aged women. Trial registration This study was registered and approved by the Regional Ethics Committee of Tampere University Hospital in Finland (approval code R15137).

The only well-established risk factors for childhood leukemia are high-dose ionizing radiation and Down syndrome. Computerized tomography is a common source of low-dose radiation. In this study, we examined the magnitude of the risk of childhood leukemia after pediatric computed tomography examinations. We evaluated the association of computed tomography scans with risk of childhood leukemia in a nationwide register-based case-control study. Cases (n=1,093) were identified from the population-based Finnish Cancer Registry and three controls, matched by gender and age, were randomly selected for each case from the Population Registry. Information was also obtained on birth weight, maternal smoking, parental socioeconomic status and background gamma radiation. Data on computed tomography scans were collected from the ten largest hospitals in Finland, covering approximately 87% of all pediatric computed tomography scans. Red bone marrow doses were estimated with NCICT dose calculation software. The data were analyzed using exact conditional logistic regression analysis. A total of 15 cases (1.4%) and ten controls (0.3%) had undergone one or more computed tomography scans, excluding a 2-year latency period. For one or more computed tomography scans, we observed an odds ratio of 2.82 (95% confidence interval: 1.05 - 7.56). Cumulative red bone marrow dose from computed tomography scans showed an excess odds ratio of 0.13 (95% confidence interval: 0.02 - 0.26) per mGy. Our results are consistent with the notion that even low doses of ionizing radiation observably increase the risk of childhood leukemia. However, the observed risk estimates are somewhat higher than those in earlier studies, probably due to random error, although unknown predisposing factors cannot be ruled out.

Background This study examined educational differences in decline in maximum gait speed over an 11-year follow-up in the general Finnish population aged 55 years and older and assessed the contribution of lifestyle factors, body mass index, physical workload, and chronic conditions on the association. Method Data from the nationally representative Health 2000 Survey and its 11-year follow-up were used. Participants aged 55 years and older with maximum gait speed measured at both time points were included (n = 1128). Information on education, age, sex, lifestyle factors, body mass index, physical workload, and chronic conditions was collected at baseline. General linear model was used to examine differences in decline in maximum gait speed between education groups. Mediation analyses using the product method was conducted to partition the total effect of education on decline in maximum gait speed into direct effect and indirect effect acting through mediators. Results Decline in maximum gait speed was greater in low and intermediate education groups in comparison to the high education group (0.24 m/s [95% confidence interval 0.21–0.26], 0.24 m/s [0.21–0.28], 0.10 m/s [0.07–0.14], respectively]. The most important mediators were higher body mass index and lifetime exposure to physical workload among the less educated, accounting for 10% and 11% of the total effect, respectively. Conclusions Education-based disparities in objectively measured mobility increase with age as lower education is associated with greater decline in gait speed. Higher body mass index and physical workload among less educated contributed most to the educational disparities in age-related decline in maximum gait speed.

Background It remains unclear whether increasing longevity is accompanied by a compression or expansion of poor health and disability. We examined trends of physical functioning and morbidity in a population aged 90 and older, and disease- and disability-free life expectancy (LE) at age 90 between 2001 and 2018 in Finland’s third most populated city. Methods We used survey data from the Vitality 90+ Study, which comprises a series of six repeated mailed surveys (7,590 observations). Information on mortality came from Statistics Finland. We examined trends of functioning (activities of daily living [ADL] and mobility) and cardiovascular and dementia morbidity using age-adjusted generalized estimating equation models stratified by sex. In addition, age-, sex-, and period-specific health expectancies were calculated using Sullivan’s method. Results Over time, functioning improved, especially, in women, and morbidity increased in men. From 2001 to 2018, LE at age 90 increased by 5.3 months for men and 6.4 months for women. LE without ADL disability increased by 5.0 months for men and 8.4 months for women, and LE without mobility disability by 6.0 months for men and 4.4 months for women. LE without cardiovascular and dementia morbidity decreased for men (2.6 months) and increased for women (1.9 months). Conclusions In relative terms, we found a compression of disability for both sexes and an expansion of morbidity for men. Although the trends overall are rather positive, the increase in absolute morbidity and, to some extent, in disability will inevitably mean increasing care needs with population aging.

Background The aim of this study was to examine associations between exposure to violence, quality of life, and psychological distress. Women aged 19–54 years who had been exposed to violence by someone in a close relationship were compared with women unexposed to violence in Finland. We also aimed to investigate associations between different forms of violence (physical, sexual, emotional, or any combination of these) with quality of life and psychological distress. Methods We selected a sample of 22,398 women who had returned self-completed questionnaires from a Finnish population-based health survey between 2013 and 2016. Exposure to violence during the past year was assessed through specific questions from the survey. The EUROHIS-QOL 8-item index was used to measure quality of life, and ordinary least square regressions were fitted. The mental health inventory (MHI-5) was used to measure psychological distress. We investigated associations with multivariate logistic regression analysis. Results Among women in Finland, the prevalence of exposure to violence in any type of close relationship during the past year was 7.6%. Women who had been exposed to violence had significantly worse scores of the EUROHIS-QOL 8-item index, and psychological distress was significantly worse (p p p Conclusions This study found that experience of close relationship violence had a negative influence on both quality of life and psychological distress among women in the general Finnish population. Comparison with victims of violence by strangers shows that some of the lower quality-of-life scores among victims are driven by the perpetrator and victim being in a close relationship. Preventive policies in primary care settings aimed at screening and educating young people should be considered as an early form of intervention to reduce the negative mental health consequences of violence.

When evaluating environmental exposures, residential exposures are often most relevant. In most countries, it is impossible to establish full residential histories. In recent publications, childhood leukaemia and background radiation have been studied with and without full residential histories. This paper investigates the consequences of lacking such full data. Data from a nationwide Finnish Case-Control study of Childhood Leukaemia and gamma rays were analysed. This included 1093 children diagnosed with leukaemia in Finland in 1990–2011. Each case was matched by gender and year of birth to three controls. Full residential histories were available. The dose estimates were based on outdoor background radiation measurements. The indoor dose rates were obtained with a dwelling type specific conversion coefficient and the individual time-weighted mean red bone marrow dose rates were calculated using age-specific indoor occupancy and the age and gender of the child. Radiation from Chernobyl fallout was included and a 2-year latency period assumed. The median separation between successive dwellings was 3.4 km and median difference in red bone marrow dose 2.9 nSv/h. The Pearson correlation between the indoor red bone marrow dose rates of successive dwellings was 0.62 (95% CI 0.60, 0.64). The odds ratio for a 10 nSv/h increase in dose rate with full residential histories was 1.01 (95% CI 0.97, 1.05). Similar odds ratios were calculated with dose rates based on only the first dwelling (1.02, 95% CI 0.99, 1.05) and only the last dwelling (1.00, 95% CI 0.98, 1.03) and for subjects who had lived only in a single dwelling (1.05, 95% CI 0.98, 1.10). Knowledge of full residential histories would always be the option of choice. However, due to the strong correlation between exposure estimates in successive dwellings and the uncertainty about the most relevant exposure period, estimation of overall exposure level from a single address is also informative. Error in dose estimation is likely to cause some degree of classical measurement error resulting in bias towards the null.

Experimental and clinical reports highlight the role of cytokines in pathophysiological processes in underpinning epilepsy, but the clinical data remains somewhat limited. The levels of Interleukin (IL)-6 were measured in serum from 49 patients with refractory epilepsy [temporal lobe epilepsy (TLE, n=23), extratemporal lobe epilepsy (XLE, n=22), and idiopathic generalized epilepsy (IGE, n=4)] before and after the first verified seizure (IS; index seizure) during inpatient video-electroencephalographic (VEEG) monitoring. The levels of IL-6 increased significantly at all time points between 3h and 24h after the IS compared to the baseline. IL-6 concentrations were significantly higher at the 3h and 6h time point after tonic-clonic seizures (TCS) compared to the situation with simple partial and complex partial seizures. An IS duration longer than 100s, low baseline IL-6 level and10 seizures/month in patients with TLE were associated with an increase in IL-6 concentrations during the 24h after the IS. In patients with TLE, the maximum change in IL-6 levels after IS was significantly higher than in XLE. If the baseline level of IL-6 was low (under 5pg/ml), seizures induced a significant elevation in both absolute and relative values in TLE patients but not in XLE. In patients with ≤10 seizures per month during the last year, the maximum change was higher than in patients with10 seizures. If the total seizure burden during registration was ≥100s, the IL-6 increase was significantly higher than if it were under 100s. The results of this study highlight the complexity of factors involved in the seizure induced production of the inflammatory cytokine, IL-6. The major factor is the epilepsy type i.e. increased production of IL-6 in TLE compared to XLE. The response to a single seizure in TLE is dependent on the previous seizure frequency and the baseline IL-6 concentration.

Objectives To identify the prognostic factors of prostate cancer death among patients enrolled in a Finnish prostate cancer screening trial. Methods Data on TNM stage, Gleason score, serum prostate-specific antigen at diagnosis, comorbidity and primary treatment were collected from medical records, as well as date and cause of death from Statistics Finland. Four prognostic risk groups were defined based on TNM stage, Gleason score and prostate-specific antigen at diagnosis. Hazard ratios and their 95% confidence intervals for prostate cancer death were calculated using Cox regression and competing-risk analysis with follow up from randomization. The differences in the effects of prognostic factors were assessed using interaction terms. Results The 15-year survival was significantly lower among cases in the control arm compared with the screening arm (0.90 vs 0.92). However, the survival advantage was limited to screen-detected cases (0.94 vs 0.91 in cases detected outside screening). The prognostic risk group was the strongest factor predicting survival in the control arm, but weaker in screen-detected cases. Advanced disease was associated with substantially poorer outcome in cases detected outside screening than in screen-detected disease. Primary treatment had a similar effect in all groups. Comorbidity had a small prognostic effect in the control arm only. Conclusions Prognostic factors had a different effect on the outcome of cases detected through screening as those diagnosed otherwise. A high diagnostic prostate-specific antigen and advanced disease carried a poor prognosis, especially among the cases detected outside screening, even when lead-time was eliminated. This shows that the screening resulted in earlier treatment among the cases in the screening arm.

Introduction The place of death is suggested as a quality indicator for end-of-life care. We investigated how the place of death changed between 1998 and 2013 among people with dementia. Methods Data from the Finnish national health and social care registers were extracted for all people with dementia, who had died at 70 years old during these years ( N = 140,034). Descriptive analysis and logistic regression analysis were conducted. Results In 2013, the most common place of death was the primary care hospital (39.8%), followed by nursing home and sheltered housing with 24-hour assistance (20.5%). Dying at home was rare (8.1%). During the study years, dying in the hospital decreased while dying in sheltered housing with 24-hour assistance increased. Discussion The place of death for people with dementia has changed from institutions to noninstitutional care facilities. Further research on noninstitutional care facilities' ability to provide high-quality care at the end of life is needed.

Long-term care (LTC) use increases with ageing due to an age-related increase in disability. Both the levels of disability and social resources vary among socioeconomic groups. The association of socioeconomic status with LTC use is largely unexplored for the oldest old. This study examined how occupational class is associated with LTC use among nonagenarians in the context of universal care coverage. A population-based prospective cohort study with 2862 participants who answered the Vitality 90 + Study surveys in 2001, 2003, 2007, or 2010 in Tampere, Finland, was combined with national register data on LTC use. LTC use in total and separately for publicly and privately provided LTC facilities was assessed in a cross-sectional setting and during the 34-month follow-up by using logistic regression and competing-risks regression methods. Functional status, multimorbidity, family relations, and help at home were controlled. In total or public LTC use, only a few differences between occupational classes were found at baseline. However, upper non-manuals used more private LTC than lower non-manuals (OR 0.54, 95% CI 0.35-0.85), skilled manuals (OR 0.40, 95% CI 0.26-0.62), or housewives (OR 0.40, 95% CI 0.22-0.74). There were no statistically significant differences in entering any kind of LTC after adjustments for all independent variables. During the study period, the share of privately provided care out of all LTC increased and the upper non-manuals no more used private care more than other groups. This study underlines the importance of following the structural changes in LTC provision to guarantee that the need for LTC is met equally for all socioeconomic groups.

Background The structure of long-term care (LTC) for old people has changed: care has been shifted from institutions to the community, and death is being postponed to increasingly old age. The aim of the study was to analyze how the use and costs of LTC in the last two years of life among old people changed between 2002 and 2013. Methods Data were derived from national registers. The study population contains all those who died at the age of 70 years or older in 2002–2013 in Finland (N = 427,078). The costs were calculated using national unit cost information. Binary logistic regression and Cox proportional hazard models were used to study the association of year of death with use and costs of LTC. Results The proportion of those who used LTC and the sum of days in LTC in the last two years of life increased between 2002 and 2013. The mean number of days in institutional LTC decreased, while that for sheltered housing increased. The costs of LTC per user decreased. Conclusions Use of LTC in the last two years of life increased, which was explained by the postponement of death to increasingly old age. Costs of LTC decreased as sheltered housing replaced institutional LTC. However, an accurate comparison of costs of different types of LTC is difficult, and the societal costs of sheltered housing are not well known.

Aim: The aim of the study was to investigate whether successful aging (SA) predicts entering long-term care (LTC) among nonagenarians. Methods: Data originated from the linkage of the Vitality 90+ Study surveys with register data from Finnish Population Register and Care Registers. Altogether 1,966 community-dwelling individuals were followed for 2 years and 1,354 individuals for 5 years. Four models of SA were constructed by varying combinations of physical, psychological, and social components. Competing risk regression analysis was used. Findings: The incidence rate for entering LTC was lower for successful agers. Three models of SA presented a significantly decreased risk for entering LTC in the whole group and in women. The impact of SA was attenuated when living alone, needing help, and the year of participation were adjusted for, but was still significant for Model 3. Conclusion: Nonagenarians who meet the multidimensional criteria of SA are less likely to enter LTC than those aging less successfully.

OBJECTIVES: Inhaled radon gas is a known alpha-emitting carcinogen linked especially to lung cancer. Studies on higher concentrations of indoor radon and childhood leukemia have conflicting but largely negative results. In this study, we aimed to create a sophisticated statistical model to predict indoor radon concentrations and apply it to a Finnish childhood leukemia case–control dataset. METHODS: Prediction was based on ~80 000 indoor radon measurements, which were linked to national registries for potential indoor radon predictors based on the literature. In modelling, we used classical methods, random forests and deep neural networks. We had 1093 cases and 3279 controls from a nationwide case–control study. We estimated odds ratio (OR) for childhood leukemia using conditional logistic regression adjusted for potential confounders. RESULTS: The r^2 of the final log-linear model was 0.21 for houses and 0.20 for apartments. Using random forest method, we were able to obtain slightly better fit for both houses (r^2 = 0.28) and apartments (r^2 = 0.23). In a risk analysis based on the case–control data with log-linear model, we observed a non-significant (P=0.54) increase with predicted radon concentrations [OR for the 2^nd quartile 1.08, 95% confidence interval (CI) 0.77–1.50, OR 1.10 with 95% CI 0.79–1.53 for the 3^rd, and 1.29 with 95% CI 0.93–1.77 for the highest quartile]. CONCLUSIONS: Our modelling and the previously published models performed similarly but involves major uncertainties, and the results should be interpreted with caution. We observed a slight non-significant increase in risk of childhood leukemia related to higher average indoor radon concentrations.

Background and Objectives: There is lack of knowledge on whether mothers&rsquo, gestational diabetes (GDM) risk is related to their physical activity (PA) or their children&rsquo, s PA and body composition. We aimed to examine the difference in (1) change in self-reported PA from pre-pregnancy to seven-year follow-up and (2) accelerometer-based PA at seven years after delivery between the mothers having GDM risk (GDMRyes-mothers) and not having GDM risk (GDMRno-mothers). Furthermore, we examined the difference in children&rsquo, s PA and/or body composition at six years of age according to their mothers&rsquo, GDM risk. Materials and Methods: The study included 199 Finnish women. GDM risk factors were screened at the beginning of pregnancy, and the women were classified as GDMRyes-mothers if they had at least one GDM risk factor (body mass index &ge, 25 kg/m2, age &ge, 40 years, family history of diabetes, GDM, signs of glucose intolerance, or newborn&rsquo, s macrosomia (&ge, 4500 g) in earlier pregnancy) or as GDMRno-mothers if they had no risk factors. Mothers&rsquo, PA was assessed by self-reporting at 8&ndash, 12 gestational weeks concerning pre-pregnancy PA and at a follow-up seven years after the delivery. Moreover, mothers&rsquo, and their children&rsquo, s PA was measured using a triaxial Hookie AM20-accelerometer at seven years after delivery. Children&rsquo, s body composition was assessed using a TANITA bioelectrical impedance device. Adjusted linear regression analyses were applied. Results: GDMRno-mothers increased their self-reported PA more than GDMRyes-mothers from pre-pregnancy to the seven-year follow-up. Concerning women&rsquo, s measured PA as well as children&rsquo, s PA and body composition at seven years after delivery, the differences were non-significant between GDMRyes-mothers and GDMRno-mothers. However, of the GDM risk factors, mothers&rsquo, pre-pregnancy body mass index was positively related to unhealthier body composition in boys at six years of age. Conclusion: Health promotion should be targeted at women with GDM risk factors, in particular overweight women, in enhancing women&rsquo, s PA in the long term and their children&rsquo, s healthy body composition.

Background: Several studies have reported increased incidence trends of malignant gliomas in the late 1900s with a plateau in the 2000s, but also some recent increases have been reported. The purpose of our study was to analyze incidence trends of malignant gliomas in Finland by morphology and tumor location. Material and methods: Data on 4730 malignant glioma patients were obtained from case notifications to the nationwide, population-based Finnish Cancer Registry (FCR), and less detailed data on 3590 patients up to 2016. Age-standardized incidence rates (ASR) and average annual percent changes (APCs) in the incidence rates were calculated by histological subtype and tumor location. Results: The incidence rate of gliomas was 7.7/100,000 in 1990-2006 and 7.3 in 2007-2016. The incidence of all gliomas combined was stable during both study periods, with no departure from linearity. In an analysis by age group, increasing incidence was found only for ages 80 years and older (1990-2006). During both study periods, incidence rates were increasing in glioblastoma and decreasing in unspecified brain tumors. In 1990-2006, rates were also increasing for anaplastic oligodendroglioma, oligoastrocytoma and unspecified malignant glioma, while decreasing for astrocytoma. As for tumor location, incidence in 1990-2006 was increasing for frontal lobe and brainstem tumors, as well as those with an unspecified location, but decreasing for the parietal lobes, cerebrum and ventricles. Conclusions: No increasing incidence trend was observed for malignant gliomas overall. An increasing incidence trend of malignant gliomas was found in the oldest age group during 1990-2006.

Background prevalence of many chronic conditions is rising in the aging population worldwide. However, the long-term impact of these conditions and multimorbidity on other health outcomes in very old age is rarely studied. Methods the data were based on four waves of the Vitality 90+ Study conducted in 2001, 2003, 2007 and 2010. Associations of chronic conditions and multimorbidity with mortality were analysed in a total sample of 2,862 people aged over 90, and associations with long-term care (LTC) admission in a subsample of 1,954 participants living at home in baseline. Risk of death and LTC admission were assessed with Cox and competing risks regression with time-dependent covariates. Population attributable fractions (PAF) for mortality and LTC admission were calculated for chronic conditions based on the regression models. Results heart disease, diabetes and dementia predicted mortality in men and women. In addition, depression was associated with increased mortality in women. Parkinson's disease, dementia and hip fracture predicted LTC admission in women. Multimorbidity increased the risk of death and LTC admission in women but not in men. For both genders, dementia had the highest PAF for mortality and LTC admission. Conclusion heart disease and diabetes are still important predictors of mortality in very old age. However, the role of dementia is pronounced in this age group. Of the studied conditions, dementia is the main contributor both to mortality and LTC admission. Multimorbidity has predictive value concerning both mortality and LTC admission, at least in oldest old women.

Increasing life expectancy has postponed the last years of life to older ages. Previous studies have demonstrated that disability is determined by age, age at death and closeness to death but only few have focused on oldest old population. We examined disability during the last years of life among people aged 90 years and older between 2001 and 2014 and assessed whether it varied by age at death, sex and study year. We used population-based survey data from the Vitality 90+ Study years 2001, 2003, 2007, 2010 and 2014 (N=5711, response rate 77-86%) linked with dates of death from Statistics Finland. Disability was defined as dependency in daily activities (dressing, getting in and out of bed) and mobility (moving indoors, walking 400m, using stairs). We analyzed disability stratified by closeness to death and age at death for men and women in each study year with logistic regression method. Disability in daily activities and mobility increased systematically with closeness to death (>4, 3-3.99, 2-2.99, 1-1.99 and 1> years to death) for both sexes in each study year. Also higher age at death (90-91 vs. 94+ years) was associated with disability. These associations remained consistent throughout the study period. This study shows that in the oldest old population both closeness to death and age at death determine the level of disability. We suggest that the complex and resource-draining care needs at the end of life will increase with growing number of people living their last years of life in very old age.

The aim of the study is (1) to describe and analyse health and social service use and medicine purchases in the last 2 years of life among older adults who died by suicide and (2) to compare use and purchases between three groups: those who died by suicide, died a natural death or who lived longer. Nation-wide Finnish register data were used. The data consist of 316,639 decedents who died at the age of 70 years or older in 1998-2008 and 222,967 people who lived longer. Use of hospital, long-term care and home care, and the purchase of prescribed psychotropic medications were studied for the 2-year period. Binary logistic regression analyses were applied. 1118 older adults died by suicide (0.4 % of all deaths). A majority of older adults who died by suicide had multiple somatic diseases and mental disorders, especially depression, and had contact with health and social services in the last 2 years of life. At the same level of morbidity, use of hospital and long-term care was less common among those who died by suicide than among those who died of natural causes, but more common than among those who lived longer. Those who died by suicide received less home care than those who lived longer. A high proportion of suicides occurred in the first month following hospital discharge. Health and social services should improve support for older adults with chronic diseases and depression.

Background The multicenter European Randomized Study of Screening for Prostate Cancer has shown a 21% reduction in prostate cancer (PC) mortality by prostate-specific antigen-based screening, with substantial overdiagnosis. In the present study, we analyzed the incidence of PC after screening in relation to the number of screening rounds attended in the Finnish section of the trial. Objective To evaluate the possible reduction in PC incidence following completed screening cycles in relation to the number of screening rounds attended. Design, setting, and participants The participants in the screening arm of the Finnish screening trial (29 298 men) were divided into subgroups of men who had participated at one, two, or three screening rounds. A reference group was formed of the 43 151 men in the control arm by selecting age-matched controls for each subgroup of the screening participants. PC cases diagnosed after screening were identified from the Finnish Cancer Registry until the end of 2011. Follow-up of the screened men started 12 mo (365 d) after the last screening attendance and a similar date was assigned to the men in the control arm. Results and limitations A total of 1514 new PCs cases (cumulative incidence 5.2%) were diagnosed among the screened men after the last screening attendance. In the reference group formed from the control arm, 2683 cases (6.2%) occurred. The hazard ratio (HR) for PC among nonparticipants in the screening arm was 0.89 (95% confidence interval [CI] 0.79–0.99) compared with their controls. Among participants, the HR in those who participated once was 1.39 (95% CI 1.22–1.57), among men who participated twice the HR was 0.97 (95% CI 0.86–1.10), and among men screened three times the HR was 0.57 (95% CI 0.49–0.68). A limitation of the study was that the comparison by attendance is not based on randomization. Conclusions The postscreening PC incidence is reduced after attending three screening rounds, but not after only one or two rounds. Thus, the increased cancer detection at screening is compensated by a subsequent risk reduction only after repeated screening cycles. Patient summary The results of the study indicate that at least three prostate-specific antigen-based screening cycles are needed to reduce subsequent prostate cancer incidence.

High doses of ionizing radiation are an established cause of childhood leukemia. However, substantial uncertainty remains about the effect of low doses of radiation, including background radiation and potential differences between genetic subgroups of leukemia have rarely been explored. We investigated the effect of the background gamma radiation on childhood leukemia using a nationwide register-based case-control study. For each of the 1,093 cases, three age- and gender matched controls were selected (N = 3,279). Conditional logistic regression analyses were adjusted for confounding by Down syndrome, birth weight (large for gestational age), and maternal smoking. Complete residential histories and previously collected survey data of the background gamma radiation in Finland were used to assess the exposure of the study subjects to indoor and outdoor gamma radiation. Overall, background gamma radiation showed a non-significant association with the OR of childhood leukemia (OR 1.01, 95% CI 0.97, 1.05 for 10 nSv/h increase in average equivalent dose rate to red bone marrow). In subgroup analyses, age group 2

The aim of this follow-up study was to explore the long-term effects of a 6-month trial of exercise training on hot flushes. The follow-up was 4 years after the exercise intervention ended.A cohort study after a randomised controlled trial. Ninety-five of the 159 randomised women (60%) participated in anthropometric measurements and performed a 2-km walk test. Participants completed a questionnaire and kept a one-week diary on physical activity, menopause symptoms and sleep quality. The frequency of 24-h hot flushes was multiplied by severity and the total sum for one week was defined as the Hot Flush Score (HFScore). Multilevel mixed regression models were analysed to compare the exercise and control groups.Hot Flush Score (HFScore) as assessed with the one-week symptom diary.The women in the exercise group had a higher probability of improved HFScore, i.e. a decrease in HFScore points, adjusted for hormone therapy (OR 0.95; 95% CI 0.90-1.00) than women in the control group at the 4-year follow-up. After additional adjustment for sleep quality, the result approached statistical significance at HFScore≥13 with women in the exercise group. Women who had the least amount of hot flushes, HFScore13, benefited most from exercise during the 4-year follow-up when compared with women in the control group.Women in the exercise group had positive effects on their HFScore 4 years after a 6-month exercise intervention.

Cell-free DNA (cf-DNA) is a marker of inflammation and cell death. The purpose of the present study was to analyze the role of cf-DNA as a putative biomarker in refractory epilepsy.Baseline concentration of cf-DNA was measured in the serum of 51 carefully evaluated refractory epilepsy patients undergoing video-EEG monitoring. Epilepsy was classified based on seizure semiology, patient history, and imaging findings. Majority of the patients (47) had focal epilepsy. The association of the concentration cf-DNA with different clinical determinants was analyzed. 250 healthy individuals served as control subjects.The mean baseline concentration of cf-DNA was lower in patients with extra temporal lobe epilepsy (XTLE) compared to control subjects (0.72 μg/ml vs. 0.80 μg/ml; p = 0.001). The difference in concentration of cf-DNA between patients with temporal lobe epilepsy (TLE) and control subjects was not significant. The maximum concentration of cf-DNA after baseline measurement was significantly lower in patients with duration of epilepsy ≥ 18 years compared to those with duration of epilepsy 18 years (0.022 μg/ml vs. 0.031 μg/ml; p = 0.044). The maximum concentration of cf-DNA was higher in patients with body mass index (BMI) ≥ 25 compared to those with BMI 25 (0.004 μg/ml vs. 0.041 μg/ml; p = 0.006).The difference in cf-DNA concentration between patients with XTLE and control subjects strengthens the previous observations of the importance of epilepsy type with regard of different biomarkers.

During acute exercise, the concentration of oxidized high-density lipoprotein (HDL) lipids (ox-HDL) is reported to increase suggesting that HDL may function in decreasing the concentration of oxidized low-density lipoprotein (LDL) lipids. However, the effect of exercise intervention on the lipid peroxide transport function of HDL is unknown. A randomized controlled trial with sedentary women (N = 161), aged 43-63, with no current use of hormone therapy, were randomized into a 6-month (mo) exercise group and a control group. During the 6-mo intervention, the concentration of ox-HDL increased in the exercise group by 5% and decreased in the control group by 2% (p = .003). Also, the ratio of ox-HDL to HDL-cholesterol increased by 5% in the exercise group and decreased by 1.5% in the control group (p = .036). The concentrations of cholesteryl ester transfer protein (CETP) and adiponectin did not change during the intervention. The concentration of serum triglycerides trended to decrease by 6% in the intervention group (p = .051). We found that the concentration of ox-HDL increased during the 6-mo aerobic exercise intervention, but the increase was not related to changes in the levels of CETP or adiponectin. These results, together with earlier studies, suggest that HDL has an active role in the reverse transport of lipid peroxides.

Purpose: The European Randomized Study of Screening for Prostate Cancer (ERSPC) has shown a 21% reduction in prostate cancer mortality by PSA-based screening. The aim of the study is to evaluate screening effect on prostate cancer incidence and mortality in relation to number of screening rounds attended. Experimental Design: The participants in the screening arm of the Finnish trial (31,867 men) were classified according to screening attendance in a time-dependent fashion. Initially, all men in the screening arm were regarded as nonattenders until the first screening attendance, then remained among the once-screened until the second screen and similarly for the possible third round. The control arm was the reference. Follow-up started at randomization and ended at death, emigration, or end of 2013. Prostate cancer incidence and mortality, as well lung cancer and overall mortality were evaluated. Results: Prostate cancer incidence was increased among screened men, but was not directly related to the number of screening rounds. Prostate cancer mortality was decreased in men screened twice or three times, but did not materially differ in those who did not attend the screening, and in men screened once compared with the control arm. The largest mortality reduction was in men screened three times [HR 0.17; 95% confidence interval (CI), 0.09–0.33]. However, a reduction was also seen in lung cancer (HR 0.59; 95% CI, 0.47–0.73) and overall mortality (HR 0.56; 95% CI, 0.52–0.60). Conclusions: Assuming a similar relative reduction being due to selection bias and screening in prostate cancer as other causes of death (40% reduction), approximately half of the observed prostate cancer mortality reduction by repeated screening is likely to be noncausal and a real screening effect may account for up to 40% reduction in men screened three times. Prostate cancer mortality reduction can only be achieved by repeated screening cycles.

Background Obesity in childhood appears often during the toddler years. The prenatal environment influences obesity risk. Maternal gestational diabetes, the child’s diet, and physical activity in the first few years have an important role in subsequent weight gain. A study was conducted to evaluate effectiveness of a primary health-care lifestyle counselling intervention in prevention of childhood obesity up to 6 years of age. Methods The study was a controlled pragmatic trial to prevent childhood obesity and was implemented at maternity and child health-care clinics. The participants (n = 185) were mothers at risk of gestational diabetes mellitus with their offspring born between 2008 and 2010. The prenatal intervention, started at the end of the first trimester of pregnancy, consisted of counselling on diet and physical activity by municipal health-care staff. The intervention continued at yearly appointments with a public health-nurse at child health-care clinics. The paper reports the offspring weight gain results for 2–6 years of age. Weight gain up to 6 years of age was assessed as BMI standard deviation scores (SDS) via a mixed-effect linear regression model. The proportion of children at 6 years with overweight/obesity was assessed as weight-for-height percentage and ISO-BMI. Priority was not given to power calculations, because of the study’s pragmatic nature. Results One hundred forty seven children’s (control n = 76/85% and intervention n = 71/56%) weight and height scores were available for analysis at 6 years of age. There was no significant difference in weight gain or overweight/obesity proportions between the groups at 6 years of age, but the proportion of children with obesity in both groups was high (assessed as ISO-BMI 9.9% and 11.8%) relative to prevalence in this age group in Finland. Conclusion As the authors previously reported, the intervention-group mothers had lower prevalence of gestational diabetes mellitus, but a decrease in obesity incidence before school age among their offspring was not found. The authors believe that an effective intervention should start before conception, continuing during pregnancy and the postpartum period through the developmentally unique child’s first years.
