Resting-state language network neuroplasticity in post-stroke music listening: A randomized controlled trial

Recent evidence suggests that post-stroke vocal music listening can aid language recovery, but the network-level functional neuroplasticity mechanisms of this effect are unknown. Here, we sought to determine if improved language recovery observed after post-stroke listening to vocal music is driven by changes in longitudinal resting-state functional connectivity within the language network. Using data from a single-blind randomized controlled trial on stroke patients (N = 38), we compared the effects of daily listening to self-selected vocal music, instrumental music and audio books on changes of the resting-state functional connectivity within the language network and their correlation to improved language skills and verbal memory during the first 3 months post-stroke. From acute to 3-month stage, the vocal music and instrumental music groups increased functional connectivity between a cluster comprising the left inferior parietal areas and the language network more than the audio book group. However, the functional connectivity increase correlated with improved verbal memory only in the vocal music group cluster. This study shows that listening to vocal music post-stroke promotes recovery of verbal memory by inducing changes in longitudinal functional connectivity in the language network. Our results conform to the variable neurodisplacement theory underpinning aphasia recovery.Peer reviewe

Sex differences in faecal occult blood test screening for colorectal cancer

Background: This analysis of patients in a randomized population-based health services study was done to determine the effects of faecal occult blood test (FOBT) screening of colorectal cancer (CRC) in outcomes beyond mortality, and to obtain explanations for potential sex differences in screening effectiveness. Methods: In the Finnish FOBT screening programme (2004-2011), people aged 60-69 years were randomized into the screening and control arms. Differences in incidence, symptoms, tumour location, TNM categories, non-vital outcomes and survival in the screening and control arms were analysed. Results: From 321 311 individuals randomized, 743 patients with screening-detected tumours and 617 control patients with CRC were analysed. CRC was less common in women than in men (0.34 versus 0.50 per cent; risk ratio (RR) 0.82, 95 per cent c.i. 0.74 to 0.91) and women were less often asymptomatic (16.7 versus 22.0 per cent; RR 0.76, 0.61 to 0.93). Women more often had right-sided tumours (32.0 versus 21.3 per cent; RR 1.51, 1.26 to 1.80). Among men with left-sided tumours, those in the screening arm had lower N (RR 1.23, 1.02 to 1.48) and M (RR 1.57, 1.14 to 2.17) categories, as well as a higher overall survival rate than those in the control arm. Furthermore among men with left-sided tumours, non-radical resections (26.2 versus 15.7 per cent; RR 1.67, 1.22 to 2.30) and postoperative chemotherapy sessions (61.6 versus 48.2 per cent; RR 1.28, 1.10 to 1.48) were more frequent in the control arm. Similar benefits of screening were not detected in men with right-sided tumours or in women. Conclusion: Biennial FOBT screening seems to be effective in terms of improving several different outcomes in men, but not in women. Differences in incidence, symptoms and tumour location may explain the differences in screening efficacy between sexes.Peer reviewe

Survival and mortality of elderly men with localized prostate cancer managed with primary androgen deprivation therapy or by primary observation

Background Androgen deprivation therapy (ADT) remains a primary treatment for localized prostate cancer (PCa) even though there is no evidence that its use is beneficial in the absence of curative treatment. Methods Men aged >= 70 years (n = 16,534) diagnosed with localized PCa from 1985 to 2014 and managed either with primary observation or ADT in the absence of curative treatment were included. The cases were identified from the population-based Finnish Cancer Registry. We estimated the standardized mortality ratios (SMR) for overall mortality by treatment group. We determined the relative risk (RR) of PCa-specific mortality (PCSM) and other-cause mortality between the two treatment groups. Survival was determined using the life table method. Two age groups (70-79 years and >= 80 years) and three calendar time cohorts (1985-1994, 1995-2004, and 2005-2014) were compared following adjustment of propensity score matching between the treatment groups with four covariates (age, year of diagnosis, educational level, and hospital district). Follow-up continued until death or until December 31, 2015. Results Patients in the observation group had lower overall SMRs than those in the ADT group in both age cohorts over the entire study period. PCSM was higher in men aged 70-79 years undergoing primary ADT compared to those managed by observation only (RR: 1.70, 95% confidence interval [CI]: 1.29-2.23 [1985-1994]; RR 1.55, 95% CI: 1.35-1.84 [1995-2004]; and RR 2.71, 95% CI: 2.08-3.53 [2005-2014]); p = 0.005 for periodic trend. A similar trend over time was also observed in men aged > 80 years; (p for age-period interaction = 0.237). Overall survival was also higher among men in their 70's managed by observation compared to those undergoing ADT. Conclusions Primary ADT within four months period from diagnosis is not associated with improved long-term overall survival or decreased PCSM compared to primary conservative management for men with localized PCa. However, this observational study's conclusions should be weighted with confounding factors related to cancer aggressiveness and comorbidities.Peer reviewe

Cancer Incidence and Mortality in the Oldest Old: a Nationwide Study in Finland

The world's population is aging rapidly. This study reports the burden of cancer in the oldest old (≥85 years) in Finland in 1953-2017 and estimates age-specific cancer rates in the old population (65-99 years) in 1988-2017. The Finnish Cancer Registry provided data on all cancer diagnoses, cancer deaths and other deaths in cancer patients in Finland in 1953-2017. Between 1953-1957 and 2013-2017, the proportion of incident cancers in those aged ≥85 years increased from 1.5% to 9.6% (597 to 15,360 new cases), and in 2013-2017, more new cancers were diagnosed at age ≥85 years than age <50 years. Cancer incidence and excess mortality attributable to cancer peaked at age 85-94 years and declined subsequently, whereas cancer-specific mortality continued to increase or plateaued. Due to demographic changes, the number of new cancers in the oldest old has increased substantially in Finland, and currently, nearly one in 10 cancers are diagnosed in this age group. The increasing cancer burden in the oldest old poses a major challenge for healthcare and needs to be addressed in designing clinical research and reporting of cancer registries. In old populations with competing risks of death, we propose excess cancer mortality as a measure of cancer-related mortality.Peer reviewe

Sex-specific familial aggregation of cancers in Finland

Despite the fact that the effect of sex on the occurrence of cancers has been studied extensively, it remains unclear whether sex modifies familial aggregation of cancers. We explored sex-specific familial aggregation of cancers in a large population-based historical cohort study. We combined cancer and population registry data, inferring familial relationships from birth municipality-surname-sex (MNS) combinations. Our data consisted of 391,529 incident primary cancers in 377,210 individuals with 319,872 different MNS combinations. Cumulative sex-specific numbers of cancers were compared to expected cumulative incidence. Familial cancer risks were similar between the sexes in our population-wide analysis. Families with concordant cancer in both sexes exhibited similar sex-specific cancer risks. However, some families had exceptionally high sex-specific cumulative cancer incidence. We identified six families with exceptionally strong aggregation in males: three families with thyroid cancer (ratio between observed and expected incidence 184.6; 95% credible interval (95% CI) 33.1-1012.7, 173.4 (95% CI 65.4-374.3), and 161.4 (95% CI 29.6-785.7), one with stomach (ratio 14.4 (95% CI 6.9-37.2)), colon (ratio 15.5 (95% CI 5.7-56.3)) cancers and one with chronic lymphocytic leukaemia (ratio 33.5 (95% CI 17.2-207.6)). Our results imply that familial aggregation of cancers shows no sex-specific preference. However, the atypical sex-specific aggregation of stomach cancer, colon cancer, thyroid cancer and chronic lymphocytic leukaemia in certain families is difficult to fully explain with present knowledge of possible causes, and could yield useful knowledge if explored further.Peer reviewe

A genome-wide scan for type 1 diabetes susceptibility genes in nuclear families with multiple affected siblings in Finland

<p>Abstract</p> <p>Background</p> <p>A genome-wide search for genes that predispose to type 1 diabetes using linkage analysis was performed using 900 microsatellite markers in 70 nuclear families with affected siblings from Finland, a population expected to be more genetically homogeneous than others, and having the highest incidence of type 1 diabetes in the world and, yet, the highest proportion in Europe of cases (10%) carrying neither of the highest risk <it>HLA </it>haplotypes that include DR3 or DR4 alleles.</p> <p>Results</p> <p>In addition to the evidence of linkage to the <it>HLA </it>region on 6p21 (nominal p = 4.0 × 10^-6), significant evidence of linkage in other chromosome regions was not detected with a single-locus analysis. The two-locus analysis conditional on the <it>HLA </it>gave a maximum lod score (MLS) of 3.1 (nominal p = 2 × 10^-4) on chromosome 9p13 under an additive model; MLS of 2.1 (nominal p = 6.1 × 10^-3) on chromosome 17p12 and MLS of 2.5 (nominal p = 2.9 × 10^-3) on chromosome 18p11 under a general model.</p> <p>Conclusion</p> <p>Our genome scan data confirmed the primary contribution of the <it>HLA </it>genes also in the high-risk Finnish population, and suggest that non-<it>HLA </it>genes also contribute to the familial clustering of type 1 diabetes in Finland.</p
