- Almost all studies of sleepy driving are carried out in driving simulators and with monotonous road conditions (no interaction with other cars). The present study investigated indicators of sleepy driving in a more challenging scenario after a night awake. 17 participants drove a high fidelity moving base driving simulator experiment while sleepiness was monitored physiologically and behaviourally. Short periods of situations of free driving (no other vehicles) alternated with short periods of following another vehicle (car following) with and without the possibility to overtake. The result showed that a night of prior sleep loss increased sleepiness levels at the wheel (eye closure duration and lateral variability) compared to after a night of normal sleep. Blink duration while overtaking was significantly lower compared to the other situations, it was at the same level as after night sleep. Speed when passing a stopped school bus was not significantly affected by sleepiness. However the warning caused a more rapid reduction of speed. In conclusion, a moderately challenging driving contest did not affect sleepiness indicators, but a very challenging one did so (overtaking). This suggests that it is important to monitor the driving situation in field operational tests of sleepy driving.

- Most people with dementia remain living at home as long as possible after being diagnosed, and hence their lives also include activities in the public space. The aim of this study was to illuminate experiences of accessibility in public space in people with Alzheimer’s disease. A qualitative grounded theory approach with repeated in-depth interviews was used. The core category, accessibility as a constantly changing experience, was characterized by changes in the relationship between informants and public space. Changes in the relationship took place in activities and use of place and related to familiarity and comfort, individual motives and interests, and planning and protecting. Other changes occurred in places and problematic situations related to everyday technologies, crowded places with high tempo and noise, and change of landmarks. These changes reduced feelings of accessibility and increased difficulties in carrying out activities in public space. These findings may be helpful when providing support, and supporting community living.

- The introduction of advanced assisted reproduction technologies (ART) has created opportunities for the treatment of infertility among patients with myelomeningocele (MMC). The aim of this study was to assess the possibility of semen retrieval and to analyse the semen quality in men with MMC. Nine men, aged 22 to 39 with MMC participated in the study. Two participants were able to achieve unassisted ejaculation. Vibratory stimulation was unsuccessfully attempted in the remaining seven participants who then underwent electroejaculation under general anaesthesia. In total, enough spermatozoa for intracytoplasmic spermatozoa injection were retrieved from five participants. In four cases, no spermatozoa were observed in the ejaculates. Testicular biopsies, however, revealed spermatogenesis, and thus a reproductive potential, in one of these men. Therefore, in six of the nine men with MMC, fatherhood seemed possible with modern ART, despite the semen quality generally being very poor.

- STUDY QUESTION What characterizes the group of donor-conceived (DC) individuals who request information about their identity-release sperm donor in Sweden, and what are their experiences of disclosure, information receipt and donor contact? SUMMARY ANSWER Following three decades of identity-release donation in Sweden, few DC individuals have requested donor information with varying experiences of information receipt and donor contact. WHAT IS KNOWN ALREADY In 1985, Sweden was the first country worldwide to enact legislation that gave DC individuals the right to obtain identifying information about their donor. Since then, identity-release gamete donation has become available in many countries but there is limited knowledge about the individuals who request donor information. STUDY DESIGN, SIZE, DURATION A nation-wide cross-sectional survey study was performed at all seven University hospitals that provided donation treatment in Sweden during 1985-2002. During this period only donor insemination to heterosexual couples was permitted. Inclusion criteria were being 18 years of age or older, conceived with donor sperm and having requested information about the donor by December 2020. Recruitment was performed during 2016-2020. PARTICIPANTS/MATERIALS, SETTING, METHODS A total of 60 individuals had requested information about their donor. Of these, 53 were approached and 40 individuals, representing 34 families, accepted study participation (75% response rate). Participants completed a postal survey with the WHO-10 well-being index and study-specific questions about experiences of disclosure, motivations for requesting donor information, receipt of information, as well as intentions and experiences of donor contact. Independent t-test and chi-square tests were used to compare ratings of participants with early and late disclosure. MAIN RESULTS AND ROLE OF CHANCE Of similar to 900 DC individuals who had reached adult age, a total of 60 (approximate to 7%) had requested information about the donor. Most of the 40 study participants (78%) made their requests within 2 years after reaching 18 years of age, or following disclosure at later ages (up to 32 years). Several participants had adult DC siblings in the family who had not requested any donor information. All except five participants received identifying information about the donor from the clinic. However, some donors had died or lacked contact information. Among those participants who were able to contact their donor, 41% had done so at the time of the study, while a third of the participants were unsure about potential contact. Several had met the donor in person and a few were in regular contact. About half of the participants had been informed about their donor conception in adolescence or adulthood (age 12-32), and there were significant differences between participants based on age at disclosure. Compared to those with early disclosure, participants with late disclosure were significantly more likely to be dissatisfied with the timing of their disclosure (P = 0.021), to react with negative emotions (P < 0.001), and to subsequently contact the donor (P = 0.047). LIMITATIONS, REASONS FOR CAUTION The limited population available for inclusion resulted in a small sample size, despite a high response rate. In addition, men's lower participation rate must be taken into consideration when interpreting the results. WIDER IMPLICATIONS OF THE FINDINGS The small number of individuals requesting information about their identity-release sperm donor is surprising. While not all DC individuals appear to be interested in donor information, it is reasonable to assume that some are unaware of their donor conception and thus unable to make informed decisions regarding their genetic origins. During the coming years, young women and men in many countries will become eligible to access identifying information about their donor. In order to meet the needs of these individuals, and to support positive outcomes for all involved parties, it is essential that adequate protocols and resources are developed.

- AIM: Primary tumours in the central nervous system (CNS) are the second most common malignancy in childhood after leukaemia. Sweden has a high incidence and a high-survival rate in international comparative studies. This has raised the question about the type of tumours included in the Swedish Cancer registry. We therefore compared international data to the Swedish Childhood Cancer registry. METHODS: Central nervous system tumours registered in the Swedish Childhood Cancer Registry were reclassified according to ICCC-3. Incidence and survival analyses were performed in the study population. RESULTS: There were 1479 children (<15 years) in Sweden diagnosed with CNS tumours 1984-2005. The distribution of diagnoses was similar to that reported in other studies. The annual incidence was 4.2/100,000 children. The survival rates have not improved significantly between the two time periods before/after 1995 (70% vs. 74%; p = 0.10). CONCLUSIONS: The mean annual incidence of children with CNS tumours was 4.2/100,000 and has not increased during the study period. Survival rate for brain tumours at 10 years follow-up was 72%.

- Vincristine is a key drug in the treatment of childhood and adult acute lymphoblastic leukemia (ALL), and many other childhood malignancies. Despite decades of wide clinical use, no data on the correlation between vincristine pharmacokinetics and long-term clinical outcome have been published. We here report clinical data (median follow-up time 10.5 years, range 7.3-12 years) for 86 children with B-cell precursor ALL, in whom vincristine kinetics were studied on treatment day 1. The median total plasma clearance was 429 and 331 ml/min per m(2) and the area under the plasma concentration-time curve (AUC) was 4.49 and 5.40 mg/l x min in relapse and non-relapse patients, respectively (not significant). In standard risk patients, where treatment depends more heavily on vincristine than in other subgroups, the relative risk (RR) of relapse was significantly increased for patients with clearance values above median (RR 5.2; P = 0.036), or AUC values below median (RR 5.8; P = 0.025). Our data suggest a relationship between the antileukemic effect and the systemic exposure of the drug, which warrants further studies.

- AIM: To evaluate the efficacy of two different Swedish screening procedures for early detection of congenital cataracts in comparison with no screening. METHODS: Children born between January 1992 and December 1998 in Swedish regions with an established eye-screening routine procedure, diagnosed with congenital cataract, and operated on before 1 y of age, were included in a retrospective study. Age at referral and age at time of the operation were compared between regions using different screening procedures: screening in the maternity wards (Region 1), at the well-baby clinics (Region 2) and one region without any screening (Region 3). RESULTS: Seventy-two children were included in the study. Concerning early diagnosis and surgery, Region 1 differed significantly from Regions 2 and 3, which were more similar and were combined for further analysis. The difference in detected cases was greatest at 21 d of age (55% vs 18%; p < 0.001), but persisted even at 100 d of age (78% vs 64%; p < 0.02). Region 1 screening resulted in more and earlier cases detected than the other two regions (22 vs 15 per 100,000 births). In 72% of all cases, surgery was performed in response to referrals from either the maternity wards (36%), or the well-baby clinics (36%). However, half of the cases from the well-baby clinics were detected too late, i.e. at > 100 d. CONCLUSION: Eye screening in the maternity ward is preferable to well-baby clinic screening and to no screening at all, since it leads to early detection. Screening should also be performed routinely at well-baby clinics within the period when successful treatment is possible.

- Aim To explore Swedish healthcare professionals' (HCPs) clinical experiences of the informed consent process (ICP) and to compare experiences between the professions. Methods In this nationwide study six paediatric oncologists (POs) and eight research nurses (ReNs) from all Swedish paediatric oncology centres were interviewed. The material was analysed using Grounded theory, a qualitative constant comparative method. Results The participants' main concern was how to fulfil research obligations without putting too much strain on a family in acute crisis, which led to the core category of balancing values and obligations of both healthcare and research. To handle the challenges the participants' struggled to safeguard the families from psychological harm, tried to adjust to the families, and gradually introduced research while building trust. The conceptual model developed in the study highlights potential consequences of this balancing act with a risk of diminishing the family's autonomy through HCPs acting authoritatively (in particular POs) or with overprotection (in particular ReNs). Conclusion Paediatric oncology is a research integrated healthcare environment. The HCPs need personal, professional and institutional support regarding ICP-related ethical issues, decisions and implications in this intertwined context. Furthermore, HCPs need to be aware of the potential long-term risk of developing professional moral distress.

- Eighty-five volunteer drivers, 65-85 years old, without cognitive impairments impacting on their driving were examined, in order to investigate driving errors characteristic for older drivers. In addition, any relationships between cognitive off-road and on-road tests results, the latter being the gold standard, were identified. Performance measurements included Trail Making Test (TMT), Nordic Stroke Driver Screening Assessment (NorSDSA), Useful Field of View (UFOV), self-rating driving performance and the two on-road protocols P-Drive and ROA. Some of the older drivers displayed questionable driving behaviour. In total, 21% of the participants failed the on-road assessment. Some of the specific errors were more serious than others. The most common driving errors embraced speed: exceeding the speed limit or not controlling the speed. Correlations with the P-Drive protocol were established for NorSDSA total score (weak), UFOV subtest 2 (weak), and UFOV subtest 3 (moderate). Correlations with the ROA protocol were established for UFOV subtest 2 (weak) and UFOV subtest 3 (weak). P-Drive and self ratings correlated weakly, whereas no correlation between self ratings and the ROA protocol was found. The results suggest that specific problems or errors seen in an older persons driving can actually be "normal driving behaviours".
