- The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since 2014 July. This paper describes the second data release from this phase, and the 14th from SDSS overall (making this Data Release Fourteen or DR14). This release makes the data taken by SDSS-IV in its first two years of operation (2014-2016 July) public. Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey; the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data-driven machine-learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from the SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS web site (www.sdss.org) has been updated for this release and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020 and will be followed by SDSS-V.

- Osteoarthritis (OA) is one of the major diseases. Physical activity has shown to have positive effects on joint cartilage and on function as well as to reduce pain among patients with OA. Patient education is one way to increase knowledge about the disease and how to cope with it. Patient education, distributed to OA-patients by a multidisciplinary team in primary health care has been used successfully in Malmö for 14 years. About 100 patients per year participate. Evaluation with Arthritis self-efficacy scale after the education-programme has shown positive effects on function and on coping with pain and other symptoms. In this article we describe the programme and our experience of patient education for OA patients in primary health care. The patient education programme is currently being evaluated with a randomized, controlled trial.

Tidskriftsartikel (refereegranskat)abstract
- Background: Osteoarthritis (OA) is a degenerative disease, considered to be one of the major public health problems. Research suggests that patient education is feasible and valuable for achieving improvements in quality of life, in function, well-being and improved coping. Since 1994, Primary Health Care in Malmo has used a patient education programme directed towards OA. The aim of this study was to evaluate the effects of this education programme for patients with OA in primary health care in terms of self-efficacy, function and self-perceived health. Method: The study was a single-blind, randomized controlled trial (RCT) in which the EuroQol-5D and Arthritis self-efficacy scale were used to measure self-perceived health and self-efficacy and function was measured with Grip Ability Test for the upper extremity and five different functional tests for the lower extremity. Results: We found differences between the intervention group and the control group, comparing the results at baseline and after 6 months in EuroQol-5D (p < 0.001) and in standing one leg eyes closed (p = 0.02) in favour of the intervention group. No other differences between the groups were found. Conclusion: This study has shown that patient education for patients with osteoarthritis is feasible in a primary health care setting and can improve self-perceived health as well as function in some degree, but not self-efficacy. Further research to investigate the effect of exercise performance on function, as well as self-efficacy is warranted.

Tidskriftsartikel (refereegranskat)abstract
- Objective Prematurity is a major risk factor for retinopathy of prematurity (ROP). We aimed to elucidate ROP prevalence, treatment and retreatment in infants born before 24 gestational age (GA) weeks in a Swedish cohort. Methods and analysis Infants with completed ROP screening, born at <24 GA weeks, 2007-2018 in Sweden were included. Data of GA, birth weight (BW), sex, neonatal morbidities, maximal ROP stage, aggressive posterior ROP (APROP), ROP treatments, treatment modality and treatment centre were retrieved. Results In total, 399 infants, with a mean GA of 23.2 weeks (range 21.9-23.9) and a mean BW of 567 g (range 340-874), were included. ROP was detected in 365 (91.5%) infants, 173 (43.4%) were treated for ROP and 68 of 173 (39.3%) were treated more than once. As the first treatment, 142 (82.0%) received laser and 29 (16.1%) received intravitreal injection of antivascular endothelial growth factor (anti-VEGF). Retreatment was performed after first laser in 46 of 142 (32.4%) and in 20 of 29 (69.0%) after first anti-VEGF treatment. Retreatment rate was not associated with GA, BW or sex but with APROP, treatment method (anti-VEGF) and treatment centre where the laser was performed (p<0.001). Twenty eyes progressed to retinal detachment, and two infants developed unilateral endophthalmitis after anti-VEGF treatment. Conclusion Infants, born at <24 weeks GA, had high rates of treatment-warranting ROP and retreatments. Treatment centre highly influenced the retreatment rate after laser indicating that laser treatment could be improved in some settings.

- This 15-year-old girl was operated due to an ectopic recurrence of a craniopharyngioma along the previous surgical route. She presented with a sellar craniopharyngioma at the age of 4 years and underwent a right subfrontal craniotomy. Two and a half years later she had a local recurrence in the sella that was resected along the same surgical route. Postoperative cranial radiotherapy was administered with 50 Gy divided into 28 fractions. Nine years later, magnetic resonance imaging (MRI) revealed a local recurrence within the sella together with a supraorbital cystic mass. Both tumors were surgically removed. Microscopic examination revealed recurrence of an adamantinous craniopharyngioma at both localisations. Histopathological preparations showed a higher MIB-1 index at the simultaneous recurrences in the sella and in the frontal lobe and also an elevated focal p53 expression, compared to previous operations, suggesting a transformation to a more aggressive tumor. This is the first case report of ectopic recurrence in a child that had received conventional radiotherapy of 50 Gy to the sella. Careful intra-operative procedure is probably crucial for preventing ectopic recurrences. The future will reveal if the transsphenoidal surgical route will put an end to ectopic tumor recurrence in patients with a craniopharyngioma.

- Objective: To explore the frequency of women seeking care during the latent phase of labour at two delivery wards. Also, to investigate interventions during labour and birth outcomes in relation to parity and remaining in hospital or not during the latent phase. Methods: A retrospective, population-based cohort study in two delivery wards in Sweden. The sample was based on electronic childbirth records of all births with spontaneous onset. Results: Of 5797 women, 17.6% (n = 1023) sought care during the latent phase. Of these, 57.8% (n = 591) remained at the hospital, and 50.5% (n = 517) had a prolonged latent phase. Nulliparae remaining in hospital had a lower rate of spontaneous vaginal births (p = 0.007), more emergency Caesarean sections (CSs) (p < 0.001) and more babies with Apgar <7 at 5 min (p = 0.045) compared with those returning home. Nulliparae having a prolonged latent phase and remaining in hospital had fewer spontaneous vaginal births (p = 0.045), more emergency CSs (p = 0.002) and more babies with Apgar <7 at 5 min (p = 0.023) compared with those returning home. For multiparous women with a previous vaginal birth, with or without prolonged latent phase, mode of delivery was not influenced by remaining in hospital or not. Conclusion: These findings indicate a need for different guidelines for nulliparous and multiparous women seeking hospital care during the latent phase, and for special attention to be given to nulliparous with a prolonged latent phase remaining in hospital during the latent phase.

Development and validation of a new clinical decision support tool to optimize screening for retinopathy of prematurity
- 2022
-
Ingår i: British Journal of Ophthalmology. - : BMJ Publishing Group Ltd. - 0007-1161 .- 1468-2079. ; 106:11, s. 1573-1580

- BACKGROUND/AIMS: Prematurely born infants undergo costly, stressful eye examinations to uncover the small fraction with retinopathy of prematurity (ROP) that needs treatment to prevent blindness. The aim was to develop a prediction tool (DIGIROP-Screen) with 100% sensitivity and high specificity to safely reduce screening of those infants not needing treatment. DIGIROP-Screen was compared with four other ROP models based on longitudinal weights.METHODS: Data, including infants born at 24-30 weeks of gestational age (GA), for DIGIROP-Screen development (DevGroup, N=6991) originate from the Swedish National Registry for ROP. Three international cohorts comprised the external validation groups (ValGroups, N=1241). Multivariable logistic regressions, over postnatal ages (PNAs) 6-14 weeks, were validated. Predictors were birth characteristics, status and age at first diagnosed ROP and essential interactions.RESULTS: ROP treatment was required in 287 (4.1%)/6991 infants in DevGroup and 49 (3.9%)/1241 in ValGroups. To allow 100% sensitivity in DevGroup, specificity at birth was 53.1% and cumulatively 60.5% at PNA 8 weeks. Applying the same cut-offs in ValGroups, specificities were similar (46.3% and 53.5%). One infant with severe malformations in ValGroups was incorrectly classified as not needing screening. For all other infants, at PNA 6-14 weeks, sensitivity was 100%. In other published models, sensitivity ranged from 88.5% to 100% and specificity ranged from 9.6% to 45.2%.CONCLUSIONS: DIGIROP-Screen, a clinical decision support tool using readily available birth and ROP screening data for infants born GA 24-30 weeks, in the European and North American populations tested can safely identify infants not needing ROP screening. DIGIROP-Screen had equal or higher sensitivity and specificity compared with other models. DIGIROP-Screen should be tested in any new cohort for validation and if not validated it can be modified using the same statistical approaches applied to a specific clinical setting.
