Variations in linear energy transfer distributions within a European proton therapy planning comparison of paediatric posterior fossa tumours.

Background And Purpose: Radiotherapy for paediatric posterior fossa tumours may cause complications in the brainstem and upper spinal cord due to high doses. With proton therapy (PT) this risk may increase due to higher relative biological effectiveness (RBE) from elevated linear energy transfer (LET). This study assesses variations in LET in the brainstem and spinal cord in proton treatment plans from European centres.

Sick leave in the prodromal phase of multiple sclerosis and its association with diagnostic delay: A short report.

The prodromal features of multiple sclerosis (MS) are non-specific and are prevalent in the general population. Several studies indicate an increased use of healthcare resources by individuals with MS in the years preceding their diagnosis, suggesting a trend of deteriorating health prior to the clinical manifestation of MS. This study aimed to capture the possible associations of sick leave with the timing of the diagnosis of MS.

Sickness absence and disability pension trajectories among individuals on sickness absence due to stress-related disorders. Two prospective population-based cohorts with 13-month follow-up.

Background: Stress-related disorders are common diagnoses for sickness absence (SA) and disability pension (DP) in many Western countries. Knowledge on future SA/DP trajectories among those starting such a SA spell is limited. The aims were to identify future SA/DP days trajectories among individuals starting an SA spell due to stress-related disorder and investigate socio-demographic and morbidity characteristics associated with specific trajectories.

Sequences of sickness absence, disability pension and unemployment four years before and five years after musculoskeletal diagnosis among Swedish twins.

Aims: To investigate sustainable working life via identification of time-related sequences of sickness absence (SA), disability pension (DP) and unemployment four years before and five years after the first musculoskeletal diagnosis in a Swedish twin cohort. Other aims were to account for familial confounding and to examine the associations between sequences and sociodemographic characteristics.

Methods: Among 28,474 Swedish twins, the patterns of interruptions of working life four years before the first M00-M99 diagnosis (MSD) and five years after MSD diagnosis were investigated with a sequence analysis in a seven-element state space consisting of sustainable working life, unemployment >90 days, moderate SA/DP (30-179 days), almost full year of SA/DP (180-365 days), full year of SA/DP (⩾ 365 days), death, and old-age pension.

Trajectories of work disability among individuals with anxiety-, mood/affective-, or stress-related disorders in a primary healthcare setting.

Background: Anxiety-, mood/affective-, or stress-related disorders affect up to one-third of individuals during their lives and often impact their ability to work. This study aimed to delineate trajectories of work disability (WD) among individuals diagnosed with anxiety-, mood/affective-, or stress-related disorder in primary healthcare and to examine associations between trajectory group membership and sociodemographic, clinical, and clinical-related factors.

Methods: The study population included working-age individuals, aged 22-62 years, living in Stockholm County, Sweden, who experienced a new episode of any anxiety-, mood/affective, or stress-related disorder in primary healthcare in 2017 (N = 11,304).

Identifying actions taken by health care professionals during procedures involving children with autism spectrum disorders in a high technological environment: Using critical incident technique.

Purpose: To explore actions taken by health care professionals during a procedure with a child with autism spectrum disorder DESIGN AND METHOD: Critical incident technique was used, which is a technique with a qualitative descriptive retrospective design, to capture situations experienced by health care professionals during a procedure in an anaesthesia or radiology department. Health care professionals from anaesthesia and radiology departments (n = 20) were interviewed about situations affecting the procedure.

Results: The findings revealed a broad range of actions (n = 205) taken by the health care professionals during a procedure with a child with autism spectrum disorder.

Psychiatric Diagnoses in Parents and Psychiatric, Behavioral, and Psychosocial Outcomes in Their Offspring: A Swedish Population-Based Register Study.

Objective: Associations were examined between six psychiatric diagnoses in parents and a broad range of psychiatric and nonpsychiatric outcomes in their offspring.

Methods: All individuals born in Sweden between 1970 and 2000 were linked to their biological parents (N=3,286,293) through Swedish national registers. A matched cohort design, with stratified Cox regression and conditional logistic regression analyses, was used examine associations between six psychiatric diagnoses in the parents and 32 outcomes in their offspring.

Clinical practice in European centres treating paediatric posterior fossa tumours with pencil beam scanning proton therapy.

Background And Purpose: As no guidelines for pencil beam scanning (PBS) proton therapy (PT) of paediatric posterior fossa (PF) tumours exist to date, this study investigated planning techniques across European PT centres, with special considerations for brainstem and spinal cord sparing.

Materials And Methods: A survey and a treatment planning comparison were initiated across nineteen European PBS-PT centres treating paediatric patients. The survey assessed all aspects of the treatment chain, including but not limited to delineations, dose constraints and treatment planning.

Molecular pixelation: spatial proteomics of single cells by sequencing.

The spatial distribution of cell surface proteins governs vital processes of the immune system such as intercellular communication and mobility. However, fluorescence microscopy has limited scalability in the multiplexing and throughput needed to drive spatial proteomics discoveries at subcellular level. We present Molecular Pixelation (MPX), an optics-free, DNA sequence-based method for spatial proteomics of single cells using antibody-oligonucleotide conjugates (AOCs) and DNA-based, nanometer-sized molecular pixels.

Coronavirus disease 2019 infection among working-aged people with multiple sclerosis and the impact of disease-modifying therapies.

Background: The risk of coronavirus disease 2019 among people with multiple sclerosis with different disease-modifying therapies is not well established.

Objective: To investigate the occurrence of coronavirus disease 2019 and the remaining symptoms among people with multiple sclerosis and the associations with different disease-modifying therapies.

Methods: Individuals aged 20-50 listed in the Swedish Multiple Sclerosis Registry were invited to participate in a survey in 2021.

Exploring the genetic etiology across the continuum of the general psychopathology factor: a Swedish population-based family and twin study.

Psychiatric comorbidity can be accounted for by a latent general psychopathology factor (p factor), which quantifies the variance that is shared to varying degrees by every dimension of psychopathology. It is unclear whether the entire continuum of the p factor shares the same genetic origin. We investigated whether mild, moderate, and extreme elevations on the p factor shared the same genetic etiology by, first, examining the linearity of the association between p factors across siblings (N = 580,891 pairs).

Childhood and adolescence outcomes in offspring to parents with bipolar disorder: the impact of lifetime parental comorbidity, parental sex, and bipolar subtype.

Background: Offspring of parents with bipolar disorder have increased risks of their own psychopathology. However, a large-scale survey of psychiatric, somatic, and adverse social outcomes up to adulthood, which could aid in prioritizing and tailoring prevention, is lacking. It also remains to clarify how risks are modified by other parental factors.

Preliminary Validation of a General Factor Model of Chronic Overlapping Pain Conditions.

Chronic overlapping pain conditions (COPCs) by definition, frequently co-occur, perhaps reflecting their shared etiologies. Their overlapping nature presents a methodological challenge, possibly masking associations between COPCs and health outcomes attributable to either general or specific processes. To address this challenge, we used population-based cohort data to evaluate the predictive validity of a bifactor model of 9 self-reported COPCs by assessing its association with incident pain-related clinical diagnoses; pain-relevant pharmacotherapy; and other health outcomes.

Associations Between General and Specific Mental Health Conditions in Young Adulthood and Cardiometabolic Complications in Middle Adulthood: A 40-Year Longitudinal Familial Coaggregation Study of 672,823 Swedish Individuals.

Objective: Most mental disorders, when examined individually, are associated with an increased risk of cardiometabolic complications. However, these associations might be attributed to a general liability to psychopathology or confounded by unmeasured familial factors. The authors investigated the association between psychiatric conditions in young adulthood and the risk of cardiometabolic complications in middle adulthood, up to 40 years later.

Children with autism spectrum disorder in high technology medicine environments; a qualitative systematic review of parental perspectives.

Background: Children with autism spectrum disorders are frequent visitors to high technology environments, and their needs may differ from those of their typically developed peers. Procedures in high technology environments can constitute a challenge for these children and their parents since the environment presents many challenges relevant to the child's impairments. This systematic review aimed to explore the experiences of children with autism spectrum disorders and their parents during procedures in a high technology environment.

Prediction of proton stopping power ratios using dual-energy CT basis material decomposition.

Background: Proton radiotherapy treatment plans are currently restricted by the range uncertainties originating from the stopping power ratio (SPR) prediction based on single-energy computed tomography (SECT). Various studies have shown that multi-energy CT (MECT) can reduce the range uncertainties due to medical implant materials and age-related variations in tissue composition. None of these has directly applied the basis material density (MD) images produced by projection-based MECT systems for SPR prediction.

Intergenerational Transmission of Psychiatric Conditions and Psychiatric, Behavioral, and Psychosocial Outcomes in Offspring.

Importance: Psychiatric conditions in parents are associated with many psychiatric and nonpsychiatric outcomes in offspring. However, it remains unknown whether this intergenerational transmission is attributable to broader psychopathology comorbidity or to specific conditions.

Objective: To estimate associations between general and specific psychopathology factors in parents and a wide range of register-based outcomes in their offspring.

Risk of unemployment and work disability among refugee and non-refugee migrants with incident psychotic disorders in Sweden and Denmark.

Background: Unemployment and work disability are common among individuals with non-affective psychotic disorders (NAPDs) but it is unknown whether rates differ among migrants and native-born individuals. The present study aimed to compare the risk of these outcomes during the first 5 years of illness in non-refugee migrants, refugees and native-born individuals with NAPDs in Sweden and Denmark-two countries with different immigration policies and models of early psychosis care.

Methods: Using national registers, we identified all individuals aged 18-35 years in Sweden and Denmark who received an incident NAPD diagnosis between 2006 and 2013 (N = 6750 and 8320, respectively).

Cost-utility of a multicomponent intervention for fibromyalgia versus usual care: a pragmatic randomised controlled trial.

Objective: To perform an economic evaluation on a multicomponent intervention programme for patients with fibromyalgia syndrome compared with usual clinical practice in primary care.

Design: A cost-utility analysis was conducted alongside a pragmatic randomised controlled trial (ClinicalTrials.gov: https://clinicaltrials.

Opportunities of measuring hierarchical models of psychopathology.

All psychiatric phenomena are positively associated, and several different models can account for this observation. These include the correlated factors, network, general psychopathology as outcome, and hierarchical models. Advantages of hierarchical models, which consist of one general and several (general factor-residualized) specific factors, is that the general factor provides an opportunity to reliably measure global distress and impairment, while the specific factors might improve the ability to discriminate between individuals with different kinds of problems.

The risk and development of work disability among individuals with gambling disorder: a longitudinal case-cohort study in Sweden.

Background: This longitudinal register study aimed to investigate the association between gambling disorder (GD) and work disability and to map work disability in subgroups of individuals with GD, three years before and three years after diagnosis.

Methods: We included individuals aged 19-62 with GD between 2005 and 2018 ( = 2830; 71.1% men, mean age: 35.

The Swedish Kinship Universe: A Demographic Account of the Number of Children, Parents, Siblings, Grandchildren, Grandparents, Aunts/Uncles, Nieces/Nephews, and Cousins Using National Population Registers.

Given that surprisingly little is known about the demography of human kinship, we provide a demographic account of the kinship networks of individuals in Sweden in 2017 across sex and cohort between ages 0 and 102. We used administrative register data of the full population of Sweden to provide the first kinship enumeration for a complete population based on empirical data. We created ego-focused kinship networks of children, parents, siblings, grandchildren, grandparents, aunts and uncles, nieces and nephews, and cousins.

Gender differences in earnings among people with multiple sclerosis and associations with type of occupation and family composition: A population-based study with matched references.

Gender differences in earnings exist worldwide. Gender segregation or familial status have been previously stated as possible explanations for these differences as well as health differences between women and men. Women are diagnosed with multiple sclerosis (MS) as twice much as men.

The nature of psychopathology.

Readers of JCPP Advances known that the dominant classification system (Diagnostic and Statistical Manual of Mental Disorders) in psychiatry and psychology conceptualizes psychopathology as discrete diagnostic categories. This measurement model builds on a strong assumption of a clear discontinuity between individuals who meet criteria for a diagnosis and those who don't fulfill diagnostic criteria. During the past decades we have seen huge efforts to test this assumption and explore alternative models, such as research from the hierarchical taxonomy of psychopathology consortia.
