Why does youth unemployment lead to scarring of depressive symptoms in adulthood? The importance of early adulthood drinking.

AIM: The aim of the paper is to analyse if alcohol consumption could explain the scarring effect of youth unemployment on later depressive symptoms. METHODS: The analyses are based on the 24-year follow-up of school leavers in a municipality in Northern Sweden (the Northern Swedish Cohort). Four-way decomposition analyses were performed to analyse if alcohol use at age 30 years could mediate and/or moderate the effect of youth unemployment (ages 18/21 years) on depressive symptoms in later adulthood (age 43 years). RESULTS: Excessive alcohol use at early adulthood (age 30 years) mediates 18% of the scarring effect of youth unemployment on depressive symptoms in later adulthood. The scarring effect was seen among both those with and without excessive alcohol use. CONCLUSIONS: Youth unemployment leads to poor mental health later in life and part of these relations are explained by excessive alcohol consumption in early adulthood. Policy interventions should target the prevention of youth unemployment for reaching a lower alcohol consumption and better mental health.

Who makes it all the way? Participants vs. decliners, and completers vs. drop-outs, in a 6-month exercise trial during cancer treatment. Results from the Phys-Can RCT.

PURPOSE: To compare sociodemographic, health- and exercise-related characteristics of participants vs. decliners, and completers vs. drop-outs, in an exercise intervention trial during cancer treatment. METHODS: Patients with newly diagnosed breast, prostate, or colorectal cancer were invited to participate in a 6-month exercise intervention. Background data for all respondents (n = 2051) were collected at baseline by questionnaire and medical records. Additional data were collected using an extended questionnaire, physical activity monitors, and fitness testing for trial participants (n = 577). Moreover, a sub-group of decliners (n = 436) consented to additional data collection by an extended questionnaire . Data were analyzed for between-group differences using independent t-tests and chi2-tests. RESULTS: Trial participants were younger (59 ± 12yrs vs. 64 ± 11yrs, p < .001), more likely to be women (80% vs. 75%, p = .012), and scheduled for chemotherapy treatment (54% vs. 34%, p < .001), compared to decliners (n = 1391). A greater proportion had university education (60% vs 40%, p < .001), reported higher anxiety and fatigue, higher exercise self-efficacy and outcome expectations, and less kinesiophobia at baseline compared to decliners. A greater proportion of trial participants were classified as 'not physically active' at baseline; however, within the group who participated, being "physically active" at baseline was associated with trial completion. Completers (n = 410) also reported less kinesiophobia than drop-outs (n = 167). CONCLUSION: The recruitment procedures used in comprehensive oncology exercise trials should specifically address barriers for participation among men, patients without university education and older patients. Individualized efforts should be made to enroll patients with low exercise self-efficacy and low outcome expectations of exercise. To retain participants in an ongoing exercise intervention, extra support may be needed for patients with kinesiophobia and those lacking health-enhancing exercise habits at baseline.

How does social support shape the association between depressive symptoms and labour market participation: a four-way decomposition.

BACKGROUND: Little is known about factors that may explain the association between depressive symptoms and poor labour market participation (LMP). The aim of this study is to examine the mediation and interaction effects of social support on the association between depressive symptoms and LMP. METHODS: Data were used from 985 participants (91% of the initial cohort) of the Northern Swedish Cohort, a longitudinal study of Swedish participants followed from adolescence throughout adulthood. Depressive symptoms were measured at age 16, social support at age 21 and LMP from age 30 to 43. Poor LMP was defined as being unemployed for a total of 6 months or more between the ages of 30 and 43. A four-way decomposition approach was applied to identify direct, mediation and interaction effects, together and separately. RESULTS: Both depressive symptoms during adolescence and social support at young adulthood were associated with poor LMP [odds ratio (OR) = 1.70, 95% confidence interval (CI) 1.17-2.47 and OR = 2.56, 95% CI 1.78-3.68 respectively]. The association between depressive symptoms and poor LMP was partially mediated by a lack of social support. No interaction effect of a lack of social support was found. CONCLUSION: The results suggest that depressive symptoms influence not only later LMP but also the intermediary level of social support, and in turn influencing later LMP. Recommendations for public health are to detect and treat depressive symptoms at an early stage and to focus on the development of social skills, facilitating the increased availability of social support, thereby improving future LMP.

Risk factors in adolescence as predictors of trajectories of somatic symptoms over 27 years.

BACKGROUND: Somatic symptoms among adolescents are common, yet little is known about long-term trajectories of somatic symptoms and the factors in adolescence that shape them. We examined individual, family and school-based factors at age 16 as predictors of trajectories of somatic symptoms over 27 years. METHODS: Participants from the Northern Swedish Cohort (n = 1001) responded to questions about individual factors (e.g. health behaviours), family factors (e.g. contact with parents, social and material adversity) and school satisfaction at age 16; as well as 10 somatic symptoms at ages 16, 18, 21, 30 and 43. Teacher assessments at age 16 included overall ability at school and peer relations. Age 16 predictors of somatic symptom trajectory group membership were analysed using multinomial logistic regression. RESULTS: Poor contact with mother and poor school satisfaction were significant predictors of adverse symptom trajectories among both men and women. Low birth weight and low parental academic involvement were contributing factors for women, while smoking and social adversity were more relevant factors for men. CONCLUSIONS: Our findings emphasize the importance of a holistic approach that considers the unique contributions of individual, family and school-based factors in the development of trajectories of somatic symptoms from adolescence to middle age.

Genetic causes of haemophilia in women and girls.

Women and girls reported as "haemophilic females" may have complex genetic causes for their haemophilia phenotype. In addition, women and girls may have excessive bleeding requiring treatment simply because they are heterozygous for haemophilia alleles. While severe and moderate haemophilia are rare in females, 16% of patients with mild haemophilia A and almost one-quarter of those with mild haemophilia B seen in U.S. haemophilia treatment centres are women and girls. A phenotypic female with a low level of factor VIII or factor IX may be classified into one of the following categories of causality: homozygosity (two identical haemophilia alleles), compound heterozygosity (two different haemophilia alleles), hemizygosity (one haemophilia allele and no normal allele), heterozygosity (one haemophilia allele and one normal allele), genetic causes other than haemophilia and non-genetic causes. Studies required for classification may include coagulation parameters, F8 or F9 sequencing, F8 inversion testing, multiplex ligation-dependent probe amplification, karyotyping and X chromosome inactivation studies performed on the patient and parents. Women and girls who are homozygous, compound heterozygous or hemizygous clearly have haemophilia, as they do not have a normal allele. Heterozygous women and girls with factor levels below the haemostatic range also meet the definitions used for haemophilia treatment.

Women and girls with haemophilia receiving care at specialized haemophilia treatment centres in the United States.

INTRODUCTION: Females may have haemophilia with the same factor VIII (FVIII) or factor IX (FIX) levels as affected males. Characterization of females with haemophilia would be useful for health care planning to meet their unique needs. Federally-funded haemophilia treatment centres (HTCs) in the United States contribute data on all individuals with bleeding disorders receiving care to the Population Profile (HTC PP) component of the Community Counts Public Health Surveillance of Bleeding Disorders project. AIMS: To estimate the number of females with haemophilia receiving care at HTCs in the United States and compare their characteristics with those of males with haemophilia. METHODS: HTC PP data collected on people receiving care at an HTC from January 2012 through September 2020 with haemophilia A and B were evaluated by sex for demographic and clinical characteristics. RESULTS: A factor level < 40% was reported for 23,196 males (97.8%) and 1667 females (47.6%) attending HTCs; 51 (.48%) severe, 79 (1.4%) moderate, and 1537 (17.9%) mild haemophilia patients were female. Females were older, more often White, and less often non-Hispanic than males. Females were less likely to have history of HIV or HCV infection, even among those with severe disease, but twice as likely to have infection status unknown. Females with mild haemophilia were more often uninsured than males. CONCLUSIONS: Females with severe or moderate haemophilia are uncommon, even in specialized care centres; however, almost one in five patients with mild haemophilia was female, indicating needs for specialized care based on factor level and history for affected females.

Segmented lateral dyke growth in a rifting event at Bárðarbunga volcanic system, Iceland.

Crust at many divergent plate boundaries forms primarily by the injection of vertical sheet-like dykes, some tens of kilometres long. Previous models of rifting events indicate either lateral dyke growth away from a feeding source, with propagation rates decreasing as the dyke lengthens, or magma flowing vertically into dykes from an underlying source, with the role of topography on the evolution of lateral dykes not clear. Here we show how a recent segmented dyke intrusion in the Bárðarbunga volcanic system grew laterally for more than 45 kilometres at a variable rate, with topography influencing the direction of propagation. Barriers at the ends of each segment were overcome by the build-up of pressure in the dyke end; then a new segment formed and dyke lengthening temporarily peaked. The dyke evolution, which occurred primarily over 14 days, was revealed by propagating seismicity, ground deformation mapped by Global Positioning System (GPS), interferometric analysis of satellite radar images (InSAR), and graben formation. The strike of the dyke segments varies from an initially radial direction away from the Bárðarbunga caldera, towards alignment with that expected from regional stress at the distal end. A model minimizing the combined strain and gravitational potential energy explains the propagation path. Dyke opening and seismicity focused at the most distal segment at any given time, and were simultaneous with magma source deflation and slow collapse at the Bárðarbunga caldera, accompanied by a series of magnitude M > 5 earthquakes. Dyke growth was slowed down by an effusive fissure eruption near the end of the dyke. Lateral dyke growth with segment barrier breaking by pressure build-up in the dyke distal end explains how focused upwelling of magma under central volcanoes is effectively redistributed over long distances to create new upper crust at divergent plate boundaries.

Trends in Sickle Cell Disease-Related Mortality in the United States, 1979 to 2017.

STUDY OBJECTIVE: We provide an updated assessment of trends in sickle cell disease (SCD)-related mortality, a significant source of mortality in the United States among black persons, using 1979 to 2017 US mortality data. METHODS: SCD-related deaths were identified with International Classification of Diseases codes. Because SCD-related death is rare in other races, the analysis focused on black decedents. Age-specific and average annual SCD-related death rates were calculated. Causes of death codes were categorized into 20 groups relevant to SCD outcomes. SCD-related deaths were compared with non-SCD-related deaths after matching on race, sex, age group, and year of death. RESULTS: There were 25,665 SCD-related deaths reported among blacks in the United States from 1979 through 2017. During that period, the annual SCD-related death rate declined in children and increased in adults, and the median age at death increased from 28 to 43 years. Acute causes of death, such as infection and cerebrovascular complications, were more common in younger age groups. Chronic complications were more common in adults. SCD-related deaths were more likely to be related to acute cardiac, pulmonary, and cerebrovascular complications; acute infections; and chronic cardiac and pulmonary complications and renal disorders; and less likely to be related to drug overdose and chronic infections than non-SCD-related deaths. CONCLUSION: These data indicate SCD-related deaths are now more likely to be related to chronic complications of the disease than to acute complications. More research regarding prevention and treatment of chronic complications of SCD is necessary because persons with SCD are living longer.

Parvovirus B19 infection in sickle cell disease: An analysis from the Centers for Disease Control haemoglobinopathy blood surveillance project.

OBJECTIVE: In the multicentre Haemoglobinopathy Blood Surveillance Project, to evaluate the seroprevalence of parvovirus B19 and DNA viral load in sickle cell disease (SCD). BACKGROUND: Although the epidemiology of parvovirus B19 seropositivity in SCD has been well documented, there are few studies that have assessed possible persistent parvovirus DNAemia and associated risk factors including blood transfusion. METHODS: A qualitative analysis of parvovirus B19 serology using ELISA and quantitative parvovirus B19 DNA by RT-PCR was performed in patients with SCD. RESULTS: Of 322 patients, 113 (35%) were parvovirus IgG positive and 119 (37%) were IgM positive at enrolment. The prevalence of IgG positivity increased with age. 71/322 (22%) were parvovirus DNA positive at enrolment with a mean viral load of 15 227 ± 55 227 SD. (range 72-329 238 IU/mL). Patients who were positive for parvovirus B19 DNA received a significantly higher red blood cell transfusion volume in the prior year compared to patients who were negative (mean RBC volume = 8310 mL vs 5435 mL, respectively; P = .0073). Seventy-seven patients had follow-up testing approximately 1 year after enrolment and 11/28 (39%) patients had persistently positive IgM. CONCLUSION: Further studies are needed to better understand the natural history of parvovirus B19 infection in SCD especially in relation to RBC transfusion as a risk factor, as well as disease outcome and severity.

Group activity participation at age 21 and depressive symptoms during boom and recession in Sweden: a 20-year follow-up.

BACKGROUND: Organized group activities (e.g. sports or arts clubs) have long been noted as important developmental settings for youth, yet previous studies on the relationships between participation and mental health outcomes have focused on short-term effects among school-aged adolescents. The subsequent period of life, emerging adulthood, has been largely overlooked despite being another important life stage where individuals face new existential challenges and may benefit from group activity participation. The potential for macroeconomic conditions to modify these relationships has also not been considered. METHODS: Participants (n = 1654) comprise two cohorts, born in either 1965 (n = 968) or 1973 (n = 686), from the same middle-sized industrial town in Northern Sweden. Both cohorts completed detailed questionnaires at age 21 (macroeconomic boom for Cohort 65, recession for Cohort 73) and approximately 20 years follow-up (age 43 for Cohort 65, age 39 for Cohort 73). General linear models were used to assess concurrent and prospective associations between regular group activity participation and depressive symptoms, as well as the potential interaction with boom/recession. RESULTS: After controlling for sociodemographic factors, regular group activity participation at age 21 was associated with lower depressive symptoms, both concurrently and at follow-up. Those exposed to recession at age 21 reported higher depressive symptoms at the time but there was no interaction between cohort (boom/recession) and group activity participation. CONCLUSIONS: Regular group activity participation during emerging adulthood is associated with lower depressive symptoms uniformly in times of boom and recession. Beneficial effects of such participation may contribute to better mental health over 20 years.

Biceps tenotomy has earlier pain relief compared to biceps tenodesis: a randomized prospective study.

PURPOSE:  Surgical management for long head of the biceps (LHB) tendinopathy with either biceps tenotomy or tenodesis is a reliable, but debated treatment option. The aim of this prospective, randomized, single-blinded study is to evaluate differences in pain relief and subjective outcomes between biceps tenotomy versus tenodesis for LHB tendinopathy. METHODS:  Subjects were randomized and blinded to biceps tenotomy versus arthroscopic tenodesis intra-operatively. Outcomes evaluated included subjective patient outcome scores, pain, and cosmetic deformity. Subjective outcomes scores and pain were analyzed using a two-way ANOVA, controlling for concomitant rotator cuff repair. Binary outcomes were compared using Chi-square tests. RESULTS:  Thirty-four subjects (31 male, 3 female) with a median age of 56 (range 30-77) were enrolled. Twenty subjects were randomized to tenotomy and 14 to tenodesis. Fifty-six percent had concomitant rotator cuff repairs. The mean VAS pain score at 3 months was lower with tenotomy versus tenodesis. 2-year follow-up demonstrated no statistically significant differences for VAS, ASES, or SANE. 15/20 (75%) subjects with biceps tenotomy reported no pain medication use at the 2-week postoperative visit versus 5/14 (33%) for biceps tenodesis. Popeye deformity was found in 5/20 (25%) of tenotomy subjects versus 1/14 (7%) in tenodesis subjects. CONCLUSION: Outcomes appear similar between biceps tenotomy versus tenodesis; however, the tenotomy group demonstrated greater incidence of cosmetic deformity but an earlier improvement in postoperative pain. LEVEL OF EVIDENCE: Treatment Studies, Level II.

Social relationships in adolescence and heavy episodic drinking from youth to midlife in Finland and Sweden - examining the role of individual, contextual and temporal factors.

BACKGROUND: Applying the Process-Person-Context-Time (PPCT) model of the bioecological theory, this study considers whether proximal processes between the individual and the microsystem (social relationships within family, peer group and school) during adolescence are associated with heavy episodic drinking (HED), from youth to midlife, and whether the macro level context (country) plays a role in these associations. METHODS: Participants of two prospective cohort studies from Finland and Sweden, recruited in 1983/1981 at age 16 (n = 2194/1080), were followed-up until their forties using postal questionnaires. Logistic regression analysis was used to examine associations between social relationships at age 16 and HED (at least monthly intoxication or having six or more units of alcohol in one occasion) at ages 22/21, 32/30 and 42/43. Additive interactions between microsystem settings, as well as between settings and country, were also considered. RESULTS: Consistent with the PPCT model, we found individual, contextual and temporal aspects to be associated with drinking habits. Higher levels of poor family relationships were associated with an increased likelihood of HED (ages 22/21 and 32/30) in both Finnish women and men and Swedish men. Higher levels of peer contact were associated with an increased likelihood of HED in both Finnish women (ages 32 and 42) and men (ages 22 and 32), and Swedish men (age 21). In contrast with the other groups, poorer relationships with classmates were associated with an increased likelihood of HED (age 30) for Swedish women only. For women, the combined effect of having both daily peer contact and living in Finland for HED at age 42/43 was statistically distinguishable from a pure additive effect. CONCLUSIONS: Micro and to a lesser extent macro level contexts are associated with heavy episodic drinking well into adulthood. The most relevant processes in the adolescent microsystem occur in family and peer settings. However, long-lasting protective or risk-raising effects between different settings and later HED were not found. Promoting good relationships across different contexts during adolescence may reduce the incidence of HED in adulthood.

Prechemotherapy robotic-assisted laparoscopic radical nephrectomy for an adolescent with Wilms tumor.

Although Wilms tumor (WT) is the most common pediatric renal tumor, adolescent and adult WT is rare. Nevertheless, adolescent renal tumors as a group are sufficiently uncommon that WT must be included in the differential diagnosis for such patients, and in doing so affects the oncologic considerations of the surgery. Herein, we describe a 14-year-old female presenting with a 1-month history of right flank pain. Subsequent work-up revealed a localized, centrally located, enhancing right renal mass. The patient underwent robotic-assisted laparoscopic radical nephrectomy and pathology demonstrated stage II, favorable histology WT. Herein, we will discuss the pertinent details regarding adolescents with renal tumors and the risks and benefits of using a minimally invasive surgical approach.

Prothrombin G20210A mutation is associated with young-onset stroke: the genetics of early-onset stroke study and meta-analysis.

BACKGROUND AND PURPOSE: Although the prothrombin G20210A mutation has been implicated as a risk factor for venous thrombosis, its role in arterial ischemic stroke is unclear, particularly among young adults. To address this issue, we examined the association between prothrombin G20210A and ischemic stroke in a white case-control population and additionally performed a meta-analysis. METHODS: From the population-based Genetics of Early Onset Stroke (GEOS) study, we identified 397 individuals of European ancestry aged 15 to 49 years with first-ever ischemic stroke and 426 matched controls. Logistic regression was used to calculate odds ratios (ORs) in the entire population and for subgroups stratified by sex, age, oral contraceptive use, migraine, and smoking status. A meta-analysis of 17 case-control studies (n=2305 cases <55 years) was also performed with and without GEOS data. RESULTS: Within GEOS, the association of the prothrombin G20210A mutation with ischemic stroke did not achieve statistical significance (OR=2.5; 95% confidence interval [CI]=0.9-6.5; P=0.07). However, among adults aged 15 to 42 years (younger than median age), cases were significantly more likely than controls to have the mutation (OR=5.9; 95% CI=1.2-28.1; P=0.03), whereas adults aged 42 to 49 years were not (OR=1.4; 95% CI=0.4-5.1; P=0.94). In our meta-analysis, the mutation was associated with significantly increased stroke risk in adults ≤55 years (OR=1.4; 95% CI=1.1-1.9; P=0.02), with significance increasing with addition of the GEOS results (OR=1.5; 95% CI=1.1-2.0; P=0.005). CONCLUSIONS: The prothrombin G20210A mutation is associated with ischemic stroke in young adults and may have an even stronger association among those with earlier onset strokes. Our finding of a stronger association in the younger young adult population requires replication.

Heme oxygenase-1 gene promoter polymorphism is associated with reduced incidence of acute chest syndrome among children with sickle cell disease.

Sickle cell disease is a common hemolytic disorder with a broad range of complications, including vaso-occlusive episodes, acute chest syndrome (ACS), pain, and stroke. Heme oxygenase-1 (gene HMOX1; protein HO-1) is the inducible, rate-limiting enzyme in the catabolism of heme and might attenuate the severity of outcomes from vaso-occlusive and hemolytic crises. A (GT)(n) dinucleotide repeat located in the promoter region of the HMOX1 gene is highly polymorphic, with long repeat lengths linked to decreased activity and inducibility. We examined this polymorphism to test the hypothesis that short alleles are associated with a decreased risk of adverse outcomes (hospitalization for pain or ACS) among a cohort of 942 children with sickle cell disease. Allele lengths varied from 13 to 45 repeats and showed a trimodal distribution. Compared with children with longer allele lengths, children with 2 shorter alleles (4%; ≤ 25 repeats) had lower rates of hospitalization for ACS (incidence rate ratio 0.28, 95% confidence interval, 0.10-0.81), after adjusting for sex, age, asthma, percentage of fetal hemoglobin, and α-globin gene deletion. No relationship was identified between allele lengths and pain rate. We provide evidence that genetic variation in HMOX1 is associated with decreased rates of hospitalization for ACS, but not pain. This study is registered at www.clinicaltrials.gov as #NCT00072761.

Assessing the mental health and psychosocial wellbeing of Ukrainian pediatric trauma and burn patients and their caregivers amidst the war: insights from a surgical medical mission in Poland.

On a recent surgical medical mission caring for Ukrainian pediatric burn and trauma patients in Poland, an assessment of the mental health and well-being of children and their caregivers was completed. Children living in war zones frequently experience significant distress and mental health problems, but little is known about the impact of co-existing related or unrelated burn injuries or physical disabilities. 19 Ukrainian children and their caregivers were interviewed utilizing validated questionnaires Child Behavioral Checklist (CBCL) and Youth Self-Report (YSR) to assess their risk for developing or for the presence of clinically-significant mental health problems. We found a high percentage of children at risk for developing mental health disorders and an unexpectedly high number of children meeting criteria for mental health disorders. As a result of interviewing the caregivers, agreement was seen between the self-assessment in children and the perception of parents about their children's wellbeing. Further study is needed to better understand the complex interactions between pre-existing burn and traumatic injuries and their impact on the psychosocial wellbeing of children living in war-torn environments.
