Co-creation of a digital platform for peer support in a community of adolescent and young adult patients during and after cancer.

PURPOSE: Adolescents and young adults (AYAs) diagnosed with cancer report psychological challenges and social isolation. Peer support has been shown to be a valuable resource for coping with these experiences. The aim of this study was through co-creation map the needs for peer support among AYA cancer patients in Sweden; and building on these results to develop and test a prototype of a digital tool for peer support. METHOD: The study was conducted in co-creation in a team consisting of AYA cancer patients, researchers, and a health tech company in Sweden. Through interviews the needs for emotional support were investigated. Based on this information, a prototype of a digital platform for peer support was co-created by the team. The platform was tested and evaluated through an online survey and follow-up interviews as part of the development process. RESULTS: AYAs expressed feelings of loneliness and a desire to process their cancer experiences with peers. A prerequisite for a digital platform for peer support was the assurance of a high degree of security. Piloting the prototype, 87% reported feeling secure, all participants found it valuable to interact with peers on the platform. In the follow-up interviews, AYAs emphasizing the need to simplify this process while maintaining stringent security measures. CONCLUSION: Co-creating tools for support together with AYAs ensures relevance and usability. A secure digital platform for peer support represents a complement to other existing forms of support. The presence of moderators was found to enhance security. Further development of the platform's log-in procedure is necessary.

Adult survivors' perceptions of their childhood and the influences of being treated for acute lymphoblastic leukaemia with allogeneic hematopoietic stem cell transplantation as a child: A phenomenographic study.

PURPOSE: Adults who had acute lymphoblastic leukaemia (ALL) as children and were treated with allogeneic hematopoietic stem cell transplantation (aHSCT) may have been affected in their lives due to several long-term complications. From a clinical point of view, it is of interest to study how survivors describe their perceptions of their childhood today. The aim was therefore to describe how adults perceived their childhood and the influences of being treated for ALL with aHSCT as a child. METHOD: Semi-structured telephone interviews were undertaken with 18 adults who had been treated for childhood ALL with aHSCT and were included in a national cohort of childhood ALL survivors, diagnosed between 1985 and 2007 at an age between 0 and 17 years. A phenomenographic analysis was used. RESULTS: Three categories emerged: Feeling different, Feeling security and Feeling guilty. The informants felt that they had been different from other children but had felt security with the healthcare professionals and in care. They felt guilty because both their siblings' and parents' lives had been affected, but at the same time many perceived that they and their family members had become closer to one another. CONCLUSIONS: The results emphasised that adults who had been treated for childhood ALL with aHSCT were affected both in negative and positive ways during their childhood. This indicates the importance for early psychosocial care interventions directed to children during their treatment, but also the need for person-centred psychological care in long-term outpatient clinics.

Novel ultrasensitive immunoassay for the selective quantification of tau oligomers and related soluble aggregates.

INTRODUCTION: Tau aggregation into paired helical filaments and neurofibrillary tangles is characteristic of Alzheimer's disease (AD) and related disorders. However, biochemical assays for the quantification of soluble, earlier-stage tau aggregates are lacking. We describe an immunoassay that is selective for tau oligomers and related soluble aggregates over monomers. METHODS: A homogeneous (single-antibody) immunoassay was developed using a novel anti-tau monoclonal antibody and validated with recombinant and brain tissue-derived tau. RESULTS: The assay signals were concentration dependent for recombinant tau aggregates in solution but not monomers, and recognized peptides within, but not outside, the aggregation-prone microtubule binding region. The signals in inferior and middle frontal cortical tissue homogenates increased with neuropathologically determined Braak staging, and were higher in insoluble than soluble homogenized brain fractions. Autopsy-verified AD gave stronger signals than other neurodegenerative diseases. DISCUSSION: The quantitative oligomer/soluble aggregate-specific assay can identify soluble tau aggregates, including oligomers, from monomers in human and in vitro biospecimens. HIGHLIGHTS: The aggregation of tau to form fibrils and neurofibrillary tangles is a key feature of Alzheimer's disease. However, biochemical assays for the quantification of oligomers/soluble aggregated forms of tau are lacking. We developed a new assay that preferentially binds to soluble tau aggregates, including oligomers and fibrils, versus monomers. The assay signal increased corresponding to the total protein content, Braak staging, and insolubility of the sequentially homogenized brain tissue fractions in an autopsy-verified cohort. The assay recognized tau peptides containing the microtubule binding region but not those covering the N- or C-terminal regions only.

A thematic analysis of how men and women post 56 years, unwind from work during their free time.

BACKGROUND: Recent research indicates that as men age, their tendency to ruminate about work decreases, while ruminating remains high in women, which poses an increased risk for impaired health among older women. OBJECTIVE: This study explored gender differences/similarities in the process of unwinding from work in men and women aged between 56-65 years. METHODS: Semi-structured qualitative interviews were conducted online with eight men and eight women, recruited from a UK leading organization that provides health care solutions between May and June 2022. Participants were asked about their job role and responsibilities, their leisure time activities, how they unwind post work, and their experiences of thinking about work related thoughts outside of work. Transcripts were analyzed using an inductive analysis. RESULTS: Three superordinate themes were identified that underpinned their ability to unwind: 'Work style', 'Creating work-life balance' and 'Switching off from one's responsibilities'. Women reported a more perfectionist approach, they set high standards for themselves, were worried about making mistakes, and demonstrated, if in a supervisory role, a more nurturing and holistic approach to their colleagues/subordinates, while men, were more focused on task completion. Most women, but not men, also described difficulties in psychologically switching off from work, and stated they could only truly relax outside the home, when they are away from household activities. CONCLUSION: The study provides nuanced insights into the experiences of unwinding from work, and the findings suggest the need for person-centric approaches in developing interventions to help workers over 56 years to psychologically disengage from work.

Did Descriptive and Prescriptive Norms About Gender Equality at Home Change During the COVID-19 Pandemic? A Cross-National Investigation.

Using data from 15 countries, this article investigates whether descriptive and prescriptive gender norms concerning housework and child care (domestic work) changed after the onset of the COVID-19 pandemic. Results of a total of 8,343 participants (M = 19.95, SD = 1.68) from two comparable student samples suggest that descriptive norms about unpaid domestic work have been affected by the pandemic, with individuals seeing mothers' relative to fathers' share of housework and child care as even larger. Moderation analyses revealed that the effect of the pandemic on descriptive norms about child care decreased with countries' increasing levels of gender equality; countries with stronger gender inequality showed a larger difference between pre- and post-pandemic. This study documents a shift in descriptive norms and discusses implications for gender equality-emphasizing the importance of addressing the additional challenges that mothers face during health-related crises.

Temporal trends in hospitalizations and 30-day mortality in older patients during the COVID pandemic from March 2020 to July 2021.

BACKGROUND: A reduction in mortality risk of COVID-19 throughout the first wave of the pandemic has been reported, but less is known about later waves. This study aimed to describe changes in hospitalizations and mortality of patients receiving inpatient geriatric care for COVID-19 or other causes during the pandemic. METHODS: Patients 70 years and older hospitalized in geriatric hospitals in Stockholm for COVID-19 or other causes between March 2020-July 2021 were included. Data on the incidence of COVID-positive cases and 30-day mortality of the total ≥ 70-year-old population, in relation to weekly hospitalizations and mortality after hospital admissions were analyzed. Findings The total number of hospitalizations was 5,320 for COVID-19 and 32,243 for non-COVID-cases. In COVID-patients, the 30-day mortality rate was highest at the beginning of the first wave (29% in March-April 2020), reached 17% at the second wave peak (November-December) followed by 11-13% in the third wave (March-July 2021). The mortality in non-COVID geriatric patients showed a similar trend, but of lower magnitude (5-10%). During the incidence peaks, COVID-19 hospitalizations displaced non-COVID geriatric patients. INTERPRETATION: Hospital admissions and 30-day mortality after hospitalizations for COVID-19 increased in periods of high community transmission, albeit with decreasing mortality rates from wave 1 to 3, with a probable vaccination effect in wave 3. Thus, the healthcare system could not compensate for the high community spread of COVID-19 during the pandemic peaks, which also led to displacing care for non-COVID geriatric patients.

Tau in cerebrospinal fluid induces neuronal hyperexcitability and alters hippocampal theta oscillations.

Alzheimer's disease (AD) and other tauopathies are characterized by the aggregation of tau into soluble and insoluble forms (including tangles and neuropil threads). In humans, a fraction of both phosphorylated and non-phosphorylated N-terminal to mid-domain tau species, are secreted into cerebrospinal fluid (CSF). Some of these CSF tau species can be measured as diagnostic and prognostic biomarkers, starting from early stages of disease. While in animal models of AD pathology, soluble tau aggregates have been shown to disrupt neuronal function, it is unclear whether the tau species present in CSF will modulate neural activity. Here, we have developed and applied a novel approach to examine the electrophysiological effects of CSF from patients with a tau-positive biomarker profile. The method involves incubation of acutely-isolated wild-type mouse hippocampal brain slices with small volumes of diluted human CSF, followed by a suite of electrophysiological recording methods to evaluate their effects on neuronal function, from single cells through to the network level. Comparison of the toxicity profiles of the same CSF samples, with and without immuno-depletion for tau, has enabled a pioneering demonstration that CSF-tau potently modulates neuronal function. We demonstrate that CSF-tau mediates an increase in neuronal excitability in single cells. We then observed, at the network level, increased input-output responses and enhanced paired-pulse facilitation as well as an increase in long-term potentiation. Finally, we show that CSF-tau modifies the generation and maintenance of hippocampal theta oscillations, which have important roles in learning and memory and are known to be altered in AD patients. Together, we describe a novel method for screening human CSF-tau to understand functional effects on neuron and network activity, which could have far-reaching benefits in understanding tau pathology, thus allowing for the development of better targeted treatments for tauopathies in the future.

Nurses' Perceptions of the Impact of a National Educational Program in Pediatric Oncology Nursing: A Cross-Sectional Evaluation.

Background: Specific knowledge is required in pediatric oncology, and specialization of nurses has been identified as a priority. In Sweden, a national program in pediatric oncology nursing has been offered since 2003. The aim of this study was to gain knowledge of nurses' perceptions of the impact of this educational program. Methods: Eighty nurses who had completed the educational program in three cohorts (2012-2019) were invited to participate in this cross-sectional survey. An electronic study-specific questionnaire containing multiple-choice questions was used. Data were analyzed using descriptive statistics and correlation tests. Results: Fifty-nine (74%) nurses completed the survey, of whom 98% responded that they would recommend the program to a large/fairly large extent. At the time of the survey, 15 (25%) participants had left pediatric oncology care. Among the remaining 44, 31 (71%) of the nurses were working bedside, and 13 (42%) of these combined this with a special position (e.g., consultant nurse). The education resulted in career advancement, as the number of nurses with special positions increased following completion of the program, from 20% to 59%. The vast majority stated that the knowledge gained from the education contributed to increased confidence in interactions with the children/families. Discussion: Continuing education of nurses in pediatric oncology has an impact on career opportunities in clinical practice and contributes to nurses' confidence and professional work. However, education is not enough to retain competent nurses. Employers need to be aware of the role of the work environment, aspects of work-life balance and career paths.

Two Years with COVID-19: The Electronic Frailty Index Identifies High-Risk Patients in the Stockholm GeroCovid Study.

INTRODUCTION: Frailty, a measure of biological aging, has been linked to worse COVID-19 outcomes. However, as the mortality differs across the COVID-19 waves, it is less clear whether a medical record-based electronic frailty index (eFI) that we have previously developed for older adults could be used for risk stratification in hospitalized COVID-19 patients. OBJECTIVES: The aim of the study was to examine the association of frailty with mortality, readmission, and length of stay in older COVID-19 patients and to compare the predictive accuracy of the eFI to other frailty and comorbidity measures. METHODS: This was a retrospective cohort study using electronic health records (EHRs) from nine geriatric clinics in Stockholm, Sweden, comprising 3,980 COVID-19 patients (mean age 81.6 years) admitted between March 2020 and March 2022. Frailty was assessed using a 48-item eFI developed for Swedish geriatric patients, the Clinical Frailty Scale, and the Hospital Frailty Risk Score. Comorbidity was measured using the Charlson Comorbidity Index. We analyzed in-hospital mortality and 30-day readmission using logistic regression, 30-day and 6-month mortality using Cox regression, and the length of stay using linear regression. Predictive accuracy of the logistic regression and Cox models was evaluated by area under the receiver operating characteristic curve (AUC) and Harrell's C-statistic, respectively. RESULTS: Across the study period, the in-hospital mortality rate decreased from 13.9% in the first wave to 3.6% in the latest (Omicron) wave. Controlling for age and sex, a 10% increment in the eFI was significantly associated with higher risks of in-hospital mortality (odds ratio = 2.95; 95% confidence interval = 2.42-3.62), 30-day mortality (hazard ratio [HR] = 2.39; 2.08-2.74), 6-month mortality (HR = 2.29; 2.04-2.56), and a longer length of stay (ß-coefficient = 2.00; 1.65-2.34) but not with 30-day readmission. The association between the eFI and in-hospital mortality remained robust across the waves, even after the vaccination rollout. Among all measures, the eFI had the best discrimination for in-hospital (AUC = 0.780), 30-day (Harrell's C = 0.733), and 6-month mortality (Harrell's C = 0.719). CONCLUSION: An eFI based on routinely collected EHRs can be applied in identifying high-risk older COVID-19 patients during the continuing pandemic.

Development of an Electronic Frailty Index for Hospitalized Older Adults in Sweden.

BACKGROUND: Frailty assessment in the Swedish health system relies on the Clinical Frailty Scale (CFS), but it requires training, in-person evaluation, and is often missing in medical records. We aimed to develop an electronic frailty index (eFI) from routinely collected electronic health records (EHRs) and assess its association with adverse outcomes in hospitalized older adults. METHODS: EHRs were extracted for 18 225 patients with unplanned admissions between 1 March 2020 and 17 June 2021 from 9 geriatric clinics in Stockholm, Sweden. A 48-item eFI was constructed using diagnostic codes, functioning and other health indicators, and laboratory data. The CFS, Hospital Frailty Risk Score, and Charlson Comorbidity Index were used for comparative assessment of the eFI. We modeled in-hospital mortality and 30-day readmission using logistic regression; 30-day and 6-month mortality using Cox regression; and length of stay using linear regression. RESULTS: Thirteen thousand one hundred and eighty-eight patients were included in analyses (mean age 83.1 years). A 0.03 increment in the eFI was associated with higher risks of in-hospital (odds ratio: 1.65; 95% confidence interval: 1.54-1.78), 30-day (hazard ratio [HR]: 1.43; 1.38-1.48), and 6-month mortality (HR: 1.34; 1.31-1.37) adjusted for age and sex. Of the frailty and comorbidity measures, the eFI had the highest area under receiver operating characteristic curve for in-hospital mortality of 0.813. Higher eFI was associated with longer length of stay, but had a rather poor discrimination for 30-day readmission. CONCLUSIONS: An EHR-based eFI has robust associations with adverse outcomes, suggesting that it can be used in risk stratification in hospitalized older adults.

Visualizing the Invisible-The Needs and Wishes of Childhood Cancer Survivors for Digitally Mediated Emotional Peer Support.

This study aims to identify the needs and wishes of childhood cancer long-term survivors for digitally mediated emotional peer support. Survivors of childhood cancer (six men, seven women) aged 19-33, participated in semi-structured interviews (November-December 2020). Age of diagnosis ranged from 1 to 13 years. The interviews lasted between 45 and 85 min. A thematic analysis was used to identify three themes for needs: processing long-term complications of cancer treatment, processing psychosocial health and meeting others who share similar experiences; and another three themes reflecting wishes: digital tools for connecting with people who had had similar experiences, different modes of communication and a safe place with varying degrees of anonymity. The findings emphasized the needs and wishes of childhood cancer survivors to meet others who had had similar experiences using a digital tool that offered a secure place, with options for a variety of communication methods and levels of anonymity. Peer support can serve as an important complement to professional psychosocial support.

Health-related quality of life in adults treated for paediatric acute lymphoblastic leukaemia: a cross-sectional and longitudinal cohort study.

INTRODUCTION: Acute lymphoblastic leukaemia (ALL) is the most common form of cancer in children. Although treatment methods have improved and resulted in significant improvement of survival and reduction in late effects and late mortality risk, the health-related quality of life (HRQOL) of survivors might be affected. To introduce new interventions in clinical practice with the potential to support positive HRQOL outcomes, more knowledge is needed on how HRQOL in this group is constructed and stimulated. The purpose of this study is to investigate how HRQOL is affected in adults treated for paediatric ALL, in a long-term perspective and possible factors influencing this relationship. METHODS AND ANALYSIS: This cohort of young adult ALL survivors allows for investigations of factors influencing HRQOL outcomes on a national level. Eligible participants are obtained from the Swedish Childhood Cancer quality registry. Data collection includes both a follow-up of data collected in 2012 (n=224) and recruitment of new eligible participants to the cohort (n=601). The cohort will cover survivors of paediatric ALL, diagnosed between 1985 and 2007, at an age between 0 and 15 years. Data will be collected using validated, multidimensional, self-administered instruments, designed to measure HRQOL (SF-36), social support, sense of coherence and resilience. ETHICS AND DISSEMINATION: The study will be carried out in accordance with the ethics permit obtained from the Swedish ethics review authority (Dnr 2019-05181). Dissemination of study results will take place through research articles and reports to the national patient organisation and the national network for consultancy nurses for this target group and to the working group for the Swedish national long-term care programme for childhood cancer. Results will also reach practical application within the follow-up clinic for adult childhood cancer survivors at Sahlgrenska Hospital in Gothenburg.

The hers and his of prosociality across 10 countries.

Is there a 'more helpful' gender? The present research assessed gender differences in prosocial self-perceptions, prosocial behavioural intentions, and prosocial (transfer) behaviour in same- and other-gender interactions in 10 countries (N = 1,915). The present results showed negligible differences in the degree to which women and men saw themselves as prosocial. However, larger gender differences emerged in regard to prosocial behavioural intentions and prosocial (transfer) behaviours across different help contexts (i.e., same- vs. other-gender interactions). In a hypothetical work scenario, women reported greater prosocial behavioural intentions than men when the recipient of the help was of the same gender. In contrast, when the recipient of the help was of the other gender, men reported greater prosocial behavioural intentions than women. In addition, men transferred more than women to both same- and other-gender interaction partners in a prisoner's dilemma game. Taken together, the present findings suggest that there is no 'more helpful' gender. Instead, gender differences in prosociality are dynamic and contextual. Different theoretical perspectives are taken into consideration in discussing gender differences in the present research.

Does the Stereotypicality of Mothers' Occupation Influence Children's Communal Occupational Aspirations and Communal Orientation?

Career development is a lifelong process that starts in infancy and is shaped by a number of different factors during childhood, adolescence, and adulthood. Even though career development is shaped through life, relatively little is known about the predictors of occupational aspirations in childhood. Therefore, in the present work we investigate how the stereotypicality of a mother's occupation (female-dominated/communal vs. non-female-dominated/agentic) influences her young child's communal occupational aspirations and communal orientation. We conducted two studies with young children. Study 1 included 72 mother-child dyads recruited from childcare centers in Northern Norway (children's age range: 4½-6 years). Study 2 included 106 mother-child dyads recruited from Norwegian elementary schools (children's age range: 6 to 13 years). Results from Study 1 showed that the stereotypicality of mothers' occupation was related to their children's communal occupational aspirations and children's communal orientation. In contrast to our predictions and results from Study 1, the stereotypicality of mothers' occupation was not significantly related to children's communal occupational aspirations nor their communal orientation in Study 2. In both studies, we found no relationship between mothers' gender attitudes or share of child care and children's communal occupational aspirations. The results are discussed in terms of parents' influence on children's development of occupational aspirations.

Worrying About Death: An Initial Analysis of Young Adult Cancer Patients' Needs.

Young adults (YAs) with cancer may have a need to develop strategies to cope with their worries about death. This brief report presents findings from a pilot study on YAs' needs with regard to such issues. An anonymous, web-based questionnaire was posted with a total of 83 cancer patients taking the questionnaire (71 females and 12 males). Almost half of the participants thought about death every day. Since most of the participants had ended their treatment, this would appear to show that matters related to death remain an important issue after the YAs' cancer treatment has ended. The results show a need for YAs to talk about death, either with professionals or with peers.

Adolescent and young adult cancer survivors' perceptions of participating in a survey - Ethical and methodological considerations.

PURPOSE: The aim of this study was to understand patient-reported perception of participation in a population-based web-survey focusing on sensitive issues for adolescent and young adult cancer survivors. METHOD: A population-based web survey for adolescent and young adult cancer survivors including a matched control group. Adolescent and young adult cancer survivors from the population-based Swedish National Cancer Registry from four of the six register holders at Regional Cancer Centers in Sweden. Controls were randomly identified from the Swedish National Population registry, from the same register holders. RESULT: Of 729 eligible participants, 540 completed the survey i.e. 74% participation rate. The study population included 285 adolescent and young adult cancer survivors and 255 matched controls. None of the participants answered that the survey had a very negative impact on them and a minority of 43 (7.9%) of the 540 responded that they were mildly negatively affected by their participation in the study. There was a no significant difference between patients and controls regarding the negative effect of the participation (p = 0.29). Positive experiences of participating in the study were widely expressed and most participants (95%) found the study valuable. CONCLUSIONS: These findings suggest that the benefits clearly outweigh the risks when adolescent and young adult cancer survivors participate in surveys including sensitive and trauma-related aspects, given that the study design is ethically sound and participants are approached carefully. We also present a modified ethical protocol for epidemiological surveys on adolescents and young adult cancer survivors.

Does Exposure to Counterstereotypical Role Models Influence Girls' and Women's Gender Stereotypes and Career Choices? A Review of Social Psychological Research.

Gender roles are formed in early childhood and continue to influence behavior through adolescence and adulthood, including the choice of academic majors and careers. In many countries, men are underrepresented in communal roles in health care, elementary education, and domestic functions (HEED fields, Croft et al., 2015), whereas women are underrepresented in the science, technology, engineering, and mathematical (STEM) fields (Beede et al., 2011) and top leadership positions (Leopold et al., 2016). Theories focusing on the development of gender roles suggest that across the lifespan people perceive certain roles to be more or less appropriate for their gender (e.g., Gender Schema Theory, Martin and Halverson, 1981; Social Role Theory, Eagly and Wood, 2011). Specifically, researchers have postulated that observing same-sex role models triggers learning processes whereby observers internalize gender-stereotypical knowledge of roles and act accordingly, which results in gender-congruent aspirations and behavior. It seems reasonable that if observing men and women in gender congruent roles fosters gender-congruent aspirations and behavior, then frequently observing gender-incongruent role models (e.g., male kindergarten teachers or female scientists and leaders) should reduce gender stereotyping and promote gender-counterstereotypical aspirations and behavior. In many countries, governments and societal decision-makers have formed initiatives based on the idea that exposure to gender-counterstereotypical role models influences aspirations and career choices among children, adolescents, and young adults. The present review gives an overview of research-based interventions involving observing or interacting with counterstereotypical role models, particularly focusing on outcomes for girls and women. Extending earlier reviews, we summarize laboratory-based and field-based studies and then critically discuss and integrate the findings in order to provide an overall picture of how counterstereotypical role models shape observers' occupational aspirations and academic choices in childhood, adolescence, and young adulthood. We conclude by outlining suggestions for future research and briefly discussing implications for future interventions.

Alzheimer-associated cerebrospinal fluid fragments of neurogranin are generated by Calpain-1 and prolyl endopeptidase.

BACKGROUND: Neurogranin (Ng) is a small 7.6 kDa postsynaptic protein that has been detected at elevated concentrations in cerebrospinal fluid (CSF) of patients with Alzheimer's disease (AD), both as a full-length molecule and as fragments from its C-terminal half. Ng is involved in postsynaptic calcium (Ca) signal transduction and memory formation via binding to calmodulin in a Ca-dependent manner. The mechanism of Ng secretion from neurons to CSF is currently unknown, but enzymatic cleavage of Ng may be of relevance. Therefore, the aim of the study was to identify the enzymes responsible for the cleavage of Ng, yielding the Ng fragment pattern of C-terminal fragments detectable and increased in CSF of AD patients. METHODS: Fluorigenic quenched FRET probes containing sequences of Ng were utilized to identify Ng cleaving activities among enzymes known to have increased activity in AD and in chromatographically fractionated mouse brain extracts. RESULTS: Human Calpain-1 and prolyl endopeptidase were identified as the candidate enzymes involved in the formation of endogenous Ng peptides present in CSF, cleaving mainly in the central region of Ng, and between amino acids 75_76 in the Ng sequence, respectively. The cleavage by Calpain-1 affects the IQ domain of Ng, which may deactivate or change the function of Ng in Ca2+/calmodulin -dependent signaling for synaptic plasticity. While shorter Ng fragments were readily cleaved in vitro by prolyl endopeptidase, the efficiency of cleavage on larger Ng fragments was much lower. CONCLUSIONS: Calpain-1 and prolyl endopeptidase cleave Ng in the IQ domain and near the C-terminus, respectively, yielding specific fragments of Ng in CSF. These fragments may give clues to the roles of increased activities of these enzymes in the pathophysiology of AD, and provide possible targets for pharmacologic intervention.

Sexual function in adolescent and young adult cancer survivors-a population-based study.

PURPOSE: Previous research has established that treatments for cancer can result in short- and long-term effects on sexual function in adult cancer patients. The purpose was to investigate patient-reported physical and psychosexual complications in adolescents and young adults after they have undergone treatment for cancer. METHODS: In this population-based study, a study-specific questionnaire was developed by a method used in several previous investigations carried out by our research group, Clinical Cancer Epidemiology. The questionnaire was developed in collaboration with adolescent and young adult cancer survivors (15-29 years) and validated by professionals from oncology units, midwives, epidemiologists, and statisticians. The topics covered in the questionnaire were psychosocial health, body image, sexuality, fertility, education, work, and leisure. The web-based questionnaire was sent to adolescent and young adult cancer survivors and matched controls in Sweden. RESULTS: In this study, adolescent and young adult cancer survivors (15-29 years) showed low satisfaction regarding sexual function compared to controls (P < 0.01). Female adolescent and young adult cancer survivors had a statistically significant lower frequency of orgasm during sexual activity than the controls (P < 0.01). Male adolescent and young adult cancer survivors had statistically significant lower sexual desire than the controls (P = 0.04). CONCLUSIONS: We found that adolescent and young adult cancer survivors perceived themselves as being less satisfied with their sexual function than matched population-based controls. IMPLICATIONS FOR CANCER SURVIVORS: Adolescent and young adult cancer survivors need psychological rehabilitation support from the health care profession during and after cancer treatment to help them to reduce their reported poor sexual function to enhance a good sexual quality of life.

Self-Perceived Physical Attractiveness in Relation to Scars Among Adolescent and Young Adult Cancer Survivors: A Population-Based Study.

OBJECTIVE: Cancer treatment may result in various effects that last long after treatment has been concluded. The purpose of this study was to explore to what extent scars affect adolescents and young adults postcancer treatment. METHODS: In this population-based study, a study-specific questionnaire was developed by a method used in several previous investigations carried out by our research group, Clinical Cancer Epidemiology. Question development involved expert validation by professionals from oncology units, midwives, epidemiologists, and statisticians. The questionnaire was developed in collaboration with adolescent and young adult cancer survivors. The topics covered in the questionnaire were as follows: psychosocial health, body image and sexuality, fertility, education, work, and leisure. The web-based questionnaire was sent to teenage and young adult cancer survivors and matched controls in Sweden. RESULTS: In this study, the relative risk of feeling less attractive due to scars was higher both for female cancer survivors RR 1.48, CI 1.05-2.08 and male cancer survivors RR 1.90, CI 1.15-3.13 compared to controls. The feeling of attractiveness was negatively related to the size of scars in both cancer and control groups. In a logistic regression analysis, significant associations were found between age, education, exercise, depression, and the feeling of low attractiveness due to scars. CONCLUSIONS: The results of this study provide a basis for care interventions for teenage and young adult cancer patients during and after cancer treatment. Further research is needed on care interventions to reduce, if possible, the impact of scars.
