Influence of modified work on return to work for employees on sick leave due to musculoskeletal complaints

Objective: To determine which individual and work-related factors are associated with performing modified work and to evaluate the influence of modified work on the duration of sick leave and health-related outcomes among employees with musculoskeletal complaints. Study design: A prospective study with 12 months follow-up. Methods: In this prospective study a total of 164 employees on sick leave for 2-6 weeks due to musculoskeletal complaints completed 2 questionnaires. At baseline we gathered information about individual characteristics, physical and psychosocial workload, and disease specific and general health. The follow-up questionnaire, sent to respondents who returned to their original job on full duty, collected information about having performed modified work, and disease-specific and general health. Results: Employees were less likely to perform modified work when their regular work was characterized by frequent lifting and their relationship with colleagues was less than good. Employees were more likely to return to modified work when they had a better mental health, had prolonged periods of standing in their regular job and had less skill discretion. Duration of sick leave was influenced by chronicity of complaints and disability, but not by modified work. Conclusion: Modified work, as the only advice given by a occupational health physician, did not influence the total duration of sick lea

Influence of modified work on recurrence of sick leave due to musculoskeletal complaints

Objectives: Workers who carry out modified work during sick leave due to musculoskeletal complaints seem to return to full-capacity work earlier than colleagues not given modified work. This study evaluates whether modified work during sick leave also influences the recurrence of a new episode of sick leave. Methods: Questionnaires on physical and psychosocial workload, musculoskeletal complaints, general health and sick leave were sent to 137 workers on sick leave for 2–6 weeks due to musculoskeletal complaints, shortly after full return to work, and 12 months after the first day of sick leave. Results: Approximately 45% of the participants experienced a recurrence of musculoskeletal sick leave within 12 months after the start of the initial sick leave. Subjects who performed modified work during initial sick leave reported significantly less recurrence than those who had started immediately at full capacity. Musculoskeletal sick leave prior to the start of the study also predicted the recurrence of sick leave. Many workers reported residual health problems at the time of return to work, which in turn influenced recurrence of musculoskeletal sickness absence. Conclusion: This study suggests that, although full recovery of musculoskeletal complaints was not established at the time of return to work, workers who had performed modified work had a lower risk of recurrence of musculoskeletal sick leave than those who had returned directly to full duties

Long-term air pollution exposure, genome-wide DNA methylation and lung function in the lifelines cohort study

BACKGROUND: Long-term air pollution exposure is negatively associated with lung function, yet the mechanisms underlying this association are not fully clear. Differential DNA methylation may explain this association. OBJECTIVES: Our main aim was to study the association between long-term air pollution exposure and DNA methylation. METHODS: We performed a genome-wide methylation study using robust linear regression models in 1,017 subjects from the LifeLines cohort study to analyze the association between exposure to nitrogen dioxide (NO2) and particulate matter (PM2.5, fine particulate ma

A Triple P review of the feasibility of sustainable offshore seaweed production in the North Sea

This study focused on the potential of seaweed, cultivated in the North Sea, as a sustainable and profitable resource for feed and non-food applications. Seawood production can take place as part of multi-use platforms at sea (MUPS). A review of the state-of-the-art in seaweed production and its applications. Various economic, ecological and social challenges are identified, which need to be addressed to utilise this potential

Twenty-eight genetic loci associated with ST-T-wave amplitudes of the electrocardiogram

The ST-segment and adjacent T-wave (ST-T wave) amplitudes of the electrocardiogram are quantitative characteristics of cardiac repolarization. Repolarization abnormalities have been linked to ventricular arrhythmias and sudden cardiac death. We performed the first genome-wide association meta-analysis of ST-T-wave amplitudes in up to 37 977 individuals identifying 71 robust genotype-phenotype associations clustered within 28 independent loci. Fifty-four genes were prioritized as candidates underlying the phenotypes, including genes with established roles in the cardiac repolarization phase (SCN5A/SCN10A, KCND3, KCNB1, NOS1AP and HEY2) and others with as yet undefined cardiac function. These associations may provide insights in the spatiotemporal contribution of genetic variation influencing cardiac repolarization and provide novel leads for future functional follow-up

Susceptibility to chronic mucus hypersecretion, a genome wide association study

Background: Chronic mucus hypersecretion (CMH) is associated with an increased frequency of respiratory infections, excess lung function decline, and increased hospitalisation and mortality rates in the general population. It is associated with smoking, but it is unknown why only a minority of smokers develops CMH. A plausible explanation for this phenomenon is a predisposing genetic constitution. Therefore, we performed a genome wide association (GWA) study of CMH in Caucasian populations. Methods: GWA analysis was performed in the NELSON-study using the Illumina 610 array, followed by replication and meta-analysis in 11 additional cohorts. In total 2,704 subjects with, and 7,624 subjects without CMH were included, all current or former heavy smokers (≥20 pack-years). Additional studies were performed to test the functional relevance of the most significant single nucleotide polymorphism (SNP). Results: A strong association with CMH, consistent across all cohorts, was observed with rs6577641 (p = 4.25x10-6, OR = 1.17), located in intron 9 of the special AT-rich sequence-binding protein 1 locus (SATB1) on chromosome 3. The risk allele (G) was associated with higher mRNA expression of SATB1 (4.3x10 -9) in lung tissue. Presence of CMH was associated with increased SATB1 mRNA expression in bronchial biopsies from COPD patients. SATB1 expression was induced during differentiation of primary human bronchial epithelial cells in culture. Conclusions: Our findings, that SNP rs6577641 is associated with CMH in multiple cohorts and is a cis-eQTL for SATB1, together with our additional observation that SATB1 expression increases during epithelial differentiation provide suggestive evidence that SATB1 is a gene that affects CMH

Meta-analysis of 49 549 individuals imputed with the 1000 Genomes Project reveals an exonic damaging variant in ANGPTL4 determining fasting TG levels

Background So far, more than 170 loci have been associated with circulating lipid levels through genomewide association studies (GWAS). These associations are largely driven by common variants, their function is often not known, and many are likely to be markers for the causal variants. In this study we aimed to identify more new rare and low-frequency functional variants associated with circulating lipid levels. Methods We used the 1000 Genomes Project as a reference panel for the imputations of GWAS data from ~60 000 individuals in the discovery stage and ~90 000 samples in the replication stage. Results Our study resu

Parental origin of sequence variants associated with complex diseases

To access publisher full text version of this article. Please click on the hyperlink in Additional Links fieldEffects of susceptibility variants may depend on from which parent they are inherited. Although many associations between sequence variants and human traits have been discovered through genome-wide associations, the impact of parental origin has largely been ignored. Here we show that for 38,167 Icelanders genotyped using single nucleotide polymorphism (SNP) chips, the parental origin of most alleles can be determined. For this we used a combination of genealogy and long-range phasing. We then focused on SNPs that associate with diseases and are within 500 kilobases of known imprinted genes. Seven independent SNP associations were examined. Five-one with breast cancer, one with basal-cell carcinoma and three with type 2 diabetes-have parental-origin-specific associations. These variants are located in two genomic regions, 11p15 and 7q32, each harbouring a cluster of imprinted genes. Furthermore, we observed a novel association between the SNP rs2334499 at 11p15 and type 2 diabetes. Here the allele that confers risk when paternally inherited is protective when maternally transmitted. We identified a differentially methylated CTCF-binding site at 11p15 and demonstrated correlation of rs2334499 with decreased methylation of that site.info:eu-repo/grantAgreement/EC/FP7/21807

Associations of autozygosity with a broad range of human phenotypes

In many species, the offspring of related parents suffer reduced reproductive success, a phenomenon known as inbreeding depression. In humans, the importance of this effect has remained unclear, partly because reproduction between close relatives is both rare and frequently associated with confounding social factors. Here, using genomic inbreeding coefficients (F-ROH) for >1.4 million individuals, we show that F-ROH is significantly associated (p <0.0005) with apparently deleterious changes in 32 out of 100 traits analysed. These changes are associated with runs of homozygosity (ROH), but not with common variant homozygosity, suggesting that genetic variants associated with inbreeding depression are predominantly rare. The effect on fertility is striking: F-ROH equivalent to the offspring of first cousins is associated with a 55% decrease [95% CI 44-66%] in the odds of having children. Finally, the effects of F-ROH are confirmed within full-sibling pairs, where the variation in F-ROH is independent of all environmental confounding.Peer reviewe
