Early Arterial Intimal Thickening and Plaque Is Related with Treatment Regime and Cardiovascular Disease Risk Factors in Young Adults Following Childhood Hematopoietic Stem Cell Transplantation

The long-term vascular effects following childhood hematopoietic stem cell transplantation (HSCT) are not well characterized. We compared arterial wall morphology and function using very-high resolution ultrasound (25–55 MHz) in 62 patients following autologous (n = 19) or allogenic (n = 43) HSCT for childhood malignancies and hematological disease (median age 25.9 years, IQR 21.1–30.1; median follow-up time 17.5 years IQR 14.1–23.0) with an age matched healthy control group (n = 44). Intima-media thickness of carotid (CIMT 0.49 ± 0.11 vs. 0.42 ± 0.06 mm, p 0.06 mm) of femoral or radial arteries (n = 17) and subclinical carotid or femoral plaques (n = 18) were more common (p 30 kg/m2, hsCRP >2.5 mg/L, hypertension, HbA1c > 42 mmol/L, and cumulative anthracycline >150 mg/m2. Cumulative metabolic syndrome criteria and cardiovascular disease (CVD) risk factors were more common among HSCT and related with CIMT (p < 0.001), but CIMT was similar among controls and HSCT without CVD risk factors. Long-term childhood HSCT survivors show early arterial aging related with radiation, metabolic, and CVD risk factors. Prevention of risk factors could potentially decelerate early arterial wall thickening

A detailed protocol for a rapid analysis of testicular cell populations using flow cytometry

Accurate analysis and quantification of different testicular cell populations are of central importance in studies of male reproductive biology. The traditional histomorphometric and immunohistochemical methods remain the gold standard in studying the complex dynamics of the testicular tissue. Through past years advances have been made in the application of flow cytometry for the rapid analysis of testicular cell populations. Detection of DNA content and of surface antigens and fluorescent reporters have been widely used to analyze and sort cells. Detection of intracellular antigens can broaden the possibilities of applying flow cytometry in studies of male reproduction. Here, we report a detailed protocol for the preparation of rat testicular tissue for detection of intracellular antigens by flow cytometry, and a pipeline for subsequent data analysis and troubleshooting. Rat testicular ontogenesis was chosen as the experimental model to validate the performance of the assay using vimentin and gamma H2AX as intracellular markers for the somatic and spermatogenic cells, respectively. The results show that the assay is reproducible and recapitulates the rat testis ontogenesis.Peer reviewe

The Transition to Upper Secondary Level After Basic Education for Adolescents with Autism Spectrum Disorder in Finland

This chapter provides an exploration of the preparation of pupils with autism spectrum disorder (ASD) for transition to upper secondary level after Finnish basic education. It also examines the importance of supports required during the transition phase. Two examples of pupils with ASD (Kalle and Maija) are utilized to illustrate how to plan and support pupils with ASD during their initial post-school transition. Transitions are defined, after which education opportunities after basic education for pupils with ASD in Finland are examined. This is followed by a brief illustration of the Finnish comprehensive school system to provide context with a focus on support arrangements and the preparation of support for transition. Then, the individual transition-planning documents are examined, after which the two cases of Kalle and Maija are introduced. This is followed by an illustration of the use of the documents in practice for the two pupils. The summary includes a discussion of implications for future directions.Peer reviewe

Sexual dysfunction in young adult survivors of childhood cancer- A population-based study

Objective: To determine the prevalence of sexual dysfunction and to identify the factors associated with sexual dysfunction in young adult childhood cancer survivors. Methods: All survivors of childhood cancer (aged 19-40 years) in Sweden were invited to this population-based study, and 2546 men and women (59%) participated. Sexual function was examined with the PROMIS Sexual Function and Satisfaction Measure. Logistic regression was used to assess the differences between survivors and a general population sample (n = 819) and to identify the factors associated with sexual dysfunction in survivors. Results: Sexual dysfunction in at least one domain was reported by 57% of female and 35% of male survivors. Among females, dysfunction was most common for Sexual interest (36%), Orgasm -ability (32%) and Vulvar discomfort -labial (19%). Among males, dysfunction was most common for the domains satisfaction with sex life (20%), Sexual interest (14%) and Erectile function ( 9%). Compared with the general population, male survivors more frequently reported sexual dysfunction in >2 domains (OR = 1.67, 95% CI: 1.03-2.71), with an increased likelihood of dysfunction regarding Orgasm -ability (OR = 1.82; 95% CI: 1.01-3.28) and Erectile function (OR = 2.30; 95% CI: 1.18-4.49). Female survivors reported more dysfunction regarding Orgasm pleasure (9% versus 5%, OR Z 1.86; 95% CI: 1.11-3.13). A more intensive cancer treatment, emotional distress and body image disturbance were associated with sexual dysfunction in survivors. Conclusions: The findings underscore the need for routine assessment of sexual health in follow-up care of childhood cancer survivors and highlight that those treated with more intensive cancer treatment and who experience concurrent psychological concerns may benefit from targeted screening and interventions. 2021 The Author(s).

Specification of human germ cell fate with enhanced progression capability supported by hindgut organoids

Human primordial germ cells (hPGCs), the precursors of sperm and eggs, are specified during weeks 2-3 after fertilization. Few studies on ex vivo and in vitro cultured human embryos reported plausible hPGCs on embryonic day (E) 12-13 and in an E16-17 gastrulating embryo. In vitro, hPGC-like cells (hPGCLCs) can be specified from the intermediary pluripotent stage or peri-gastrulation precursors. Here, we explore the broad spectrum of hPGCLC precursors and how different precursors impact hPGCLC development. We show that resetting precursors can give rise to hPGCLCs (rhPGCLCs) in response to BMP. Strikingly, rhPGCLCs co-cultured with human hindgut organoids progress at a pace reminiscent of in vivo hPGC devel-opment, unlike those derived from peri-gastrulation precursors. Moreover, rhPGCLC specification depends on both EOMES and TBXT, not just on EOMES as for peri-gastrulation hPGCLCs. Importantly, our study pro-vides the foundation for developing efficient in vitro models of human gametogenesis.Peer reviewe

Physical Fitness and Frailty in Males after Allogeneic Hematopoietic Stem Cell Transplantation in Childhood: A Long-Term Follow-Up Study

Purpose and methods: To analyze physical fitness, physical activity and the prevalence of frailty in male long-term survivors of pediatric allogeneic hematopoietic stem cell transplantation (HSCT). We performed a Nordic two-center study of 98 male survivors (mean age 28.7 years, range 18.5–47.0) treated with pediatric allogeneic hematopoietic stem cell transplantation (HSCT) 1980–2010 in denmark or finland. physical fitness was evaluated by the dominant hand grip-strength, timed up-and-go, sit-to-stand, gait speed and two-minute walk tests. Results: Survivors presented significantly lower muscle strength and muscle endurance in the dominant hand-grip strength (median Z-score −0.7, range −4.3–3.9) and sit-to-stand tests (median Z-score −1.5, range −3.5–2.5) compared to age and sex matched normative values of the tests. However, mobility and gait speed were not affected on a group level. The prevalence of frailty (pre-frail 20% or frail 10%) was high among the survivors. In multiple regression analysis, chronic graft-versus-host disease, shorter stature, higher body fat mass and hazardous drinking predicted prefrail/frail status. Common cardiovascular risk factors, such as increased levels of serum triglycerides, higher resting heart rate and diastolic blood pressure, were associated with lower physical fitness. Conclusion: Low muscle strength and a high incidence of frailty were observed in survivors of pediatric HSCT. There is a predominant risk of cardiovascular and metabolic diseases in the long-term

Physical Fitness and Frailty in Males after Allogeneic Hematopoietic Stem Cell Transplantation in Childhood : A Long-Term Follow-Up Study

Simple Summary The prevalence of frailty is increased among young adult childhood cancer survivors and is associated with early morbidity and mortality. The aim of our study was to analyze physical fitness, physical activity and the prevalence of frailty in male long-term survivors of pediatric allogeneic hematopoietic stem cell transplantation. We observed significantly lower muscle strength and muscle endurance in the hand-grip and sit-to-stand tests compared to the age and sex matched normative reference values of the tests. Furthermore, 30% of the survivors were considered pre-frail or frail. Chronic graft-versus-host disease, shorter stature, higher body fat mass and hazardous drinking predicted prefrail/frail status. Common cardiovascular risk factors were associated with poor physical fitness and low physical activity level. These results indicate a need for cardiometabolic follow up as well as health education in the decades following HSCT. Purpose and methods: To analyze physical fitness, physical activity and the prevalence of frailty in male long-term survivors of pediatric allogeneic hematopoietic stem cell transplantation (HSCT).
