- 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.

- Introduction Gallbladder cancer is a rare but aggressive malignancy. Surgical resection is recommended for gallbladder polyps >= 10 mm. For gallbladder wall thickening, resection is recommended if malignancy cannot be excluded. The incidence of gallbladder malignancy after cholecystectomy with indications of polyps or wall thickening in the Swedish population is not known. Material/methods A retrospective study was performed at Linkoping University Hospital and included patients who underwent cholecystectomy 2010 - 2018. All cholecystectomies performed due to gallbladder polyps or gallbladder wall thickening without other preoperative malignant signs were identified. Preoperative radiological examinations were re-analysed by a single radiologist. Medical records and histopathology reports were analysed. Results In all, 102 patients were included, of whom 65 were diagnosed with gallbladder polyps and 37 with gallbladder wall thickening. In each group, one patient (1.5% and 2.7% in each group) had gallbladder malignancy >= pT1b.Two (3.1%) and three (8.1%) patients with gallbladder malignancy < T1b were identified in each group. Discussion/conclusion This study indicates that the incidence of malignancy is low without other malignant signs beyond gallbladder polyps and/or gallbladder wall thickening. We propose that these patients should be discussed at a multidisciplinary tumour board. If the polyp is 10-15 mm or if the gallbladder wall is thickened but no other malignant signs are observed, cholecystectomy can be safely performed by an experienced general surgeon at a general surgery unit. If the histopathology indicates >= pT1b, the patient should be referred immediately to a hepatobiliary centre for liver and lymph node resection.

Tidskriftsartikel (refereegranskat)abstract
- Objective: Experiences of trauma, specifically sexual abuse, have been linked to both mental health and substance use disorders. This study used 14 years of Swedish health registry data to select a sample of adult men who reported frequent opioid use and assessed if those with a self-reported history of sexual abuse had a higher likelihood of hospitalization for a mental health disorder.Methods: A Swedish longitudinal (2003–2017) registry study linked Addiction Severity Index (ASI) assessments completed with individuals who sought treatment for substance use disorders with data on hospitalizations for mental health disorders, and assessed associations with self-reported histories of sexual abuse among men who reported sustained and frequent use of opioids (n¼1862). Cox regression methods tested associations and controlled for age, and the7 ASI composite scores: family and social relationships, employment, alcohol use, drug use, legal, physical health, and mental health.Results: The ASI composite score for mental health (hazard ratio[HR] 16.6, P<0.001) and a history of sexual abuse (HR 1.93,P<0.001) were associated with an elevated risk of future mental health hospitalization.Conclusion: Both the ASI composite scores for mental health andself-reported history of sexual abuse reflected complex needs amongmen who used opioids and increased risk for mental health hospitalization.Treatment providers should strive to provide integrated careand address the negative aspects of victimization.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- On 19 January 2014 Rolf (Roffe') Bernander passed away unexpectedly. Rolf was a dedicated scientist; his research aimed at unravelling the cell biology of the archaeal domain of life, especially cell cycle-related questions, but he also made important contributions in other areas of microbiology. Rolf had a professor position in the Molecular Evolution programme at Uppsala University, Sweden for about 8 years, and in January 2013 he became chair professor at the Department of Molecular Biosciences, The Wenner-Gren Institute at Stockholm University in Sweden. Rolf was an exceptional colleague and will be deeply missed by his family and friends, and the colleagues and co-workers that he leaves behind in the scientific community. He will be remembered for his endless enthusiasm for science, his analytical mind, and his quirky sense of humour.

Communicating Intent of Automated Vehicles to Pedestrians.
- 2018
-
Ingår i: Frontiers in Psychology. - Lausanne : Frontiers Media SA. - 1664-1078. ; 9
-
Tidskriftsartikel (refereegranskat)abstract
- While traffic signals, signs, and road markings provide explicit guidelines for those operating in and around the roadways, some decisions, such as determinations of "who will go first," are made by implicit negotiations between road users. In such situations, pedestrians are today often dependent on cues in drivers' behavior such as eye contact, postures, and gestures. With the introduction of more automated functions and the transfer of control from the driver to the vehicle, pedestrians cannot rely on such non-verbal cues anymore. To study how the interaction between pedestrians and automated vehicles (AVs) might look like in the future, and how this might be affected if AVs were to communicate their intent to pedestrians, we designed an external vehicle interface called automated vehicle interaction principle (AVIP) that communicates vehicles' mode and intent to pedestrians. The interaction was explored in two experiments using a Wizard of Oz approach to simulate automated driving. The first experiment was carried out at a zebra crossing and involved nine pedestrians. While it focused mainly on assessing the usability of the interface, it also revealed initial indications related to pedestrians' emotions and perceived safety when encountering an AV with/without the interface. The second experiment was carried out in a parking lot and involved 24 pedestrians, which enabled a more detailed assessment of pedestrians' perceived safety when encountering an AV, both with and without the interface. For comparison purposes, these pedestrians also encountered a conventional vehicle. After a short training course, the interface was deemed easy for the pedestrians to interpret. The pedestrians stated that they felt significantly less safe when they encountered the AV without the interface, compared to the conventional vehicle and the AV with the interface. This suggests that the interface could contribute to a positive experience and improved perceived safety in pedestrian encounters with AVs - something that might be important for general acceptance of AVs. As such, this topic should be further investigated in future studies involving a larger sample and more dynamic conditions.

A Database of Static Clothing Thermal Insulation and Vapor Permeability Values of Non-Western Ensembles for Use in ASHRAE Standard 55, ISO 7730 and ISO 9920
- 2015

Ingår i: ASHRAE Transactions. - 2378-2129. ; 121:Part 1, s. 197-215

Tidskriftsartikel (refereegranskat)abstract
- Four different thermal manikins (male and female shapes)in three different laboratories (UK, Sweden, and China) were used to determine the clothing thermal insulation values of 52 non-Western, mainly indoor clothing ensembles in order to expand the existing clothing database for use with ANSI/ASHRAE Standard 55-2013, Thermal Environmental Conditions for Human Occupancy (ASHRAE 2013a), ISO Standard 7730-2005, Ergonomics of the Thermal Environment -- Analytical Determination and Interpretation of Thermal Comfort Using Calculation of the PMV and PPD Indices and LocalThermal Comfort Criteria (ISO 2005), and ISO Standard 9920-2009, Ergonomics of the Thermal Environment -- Estimation of Thermal Insulation and Water Vapour Resistance of a Clothing Ensemble (ISO 2009). Insulation values varied over manikins, which is attributed to their different shapes and the different fit of the clothing. The mean value over three manikins is reported (with standard deviation) to include this potential real-life variation in the results. The relation of the clothing surface area factor to intrinsic clothing insulation was found to be different from that published for Western clothing. Prediction equations for the clothing surface area factor fcl based on the new data had only limited predictive power, which,however, was also the case for those obtained in the past for Western clothing. This issue seems to be commonly overlooked, as the use of these prediction equations is widespread. It has to be concluded that reliable fcl values can only be obtained when they are actually measured, as in the present work. However, we suggest that the concept of the fcl factor for the non-Western clothing may not be appropriate and may require further attention in research, as wide-falling-robes and gowns do not match the cylindrical clothing and air layer model on which the fcl concept is based. In summary, the results provide an extensive database of insulation values of non-Western clothing that is expected to be a valuable addition to ASHRAE Standard 55-2013 (ASHRAE 2013a), ISO Standard 7730-2005 (ISO 2005), and ISO Standard 9920-2009 (ISO 2009).

Hospital admission rate, cumulative hospitalized days, and time to admission among older persons with substance use and psychiatric conditions
- 2022
-
Ingår i: Frontiers in Psychiatry. - : Frontiers Media S.A.. - 1664-0640. ; 13
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Substance use among older persons occurs with medical and psychiatric comorbidities. This study examined the associations of substance use disorder (SUD), psychiatric, and dual diagnoses with 12-month cumulative hospitalized days, hospital admission rate and number of days to first hospitalization.Methods: The cohort of 3,624 individuals (28.2% women) aged 50 years or older was assessed for substance use severity in 65 Swedish municipalities during March 2003–May 2017. Addiction Severity Index data were linked to hospital discharge records and crime statistics. The outcomes were (a) 12-month cumulative hospitalized days; (b) Hospital admission rate, and (c) days to first hospitalization. Generalized linear regression techniques investigated associations between outcomes and SUD, psychiatric and dual diagnoses at admission.Results: During 2003–2017, 73.5% of the participants were hospitalized. Twelve-month hospitalized days were positively associated with SUD (Incidence rate ratio (IRR) = 1.41, 95%CI: 1.26–1.58), dual diagnosis (IRR = 2.03, 95%CI: 1.74–2.36), and psychiatric diagnoses (IRR = 2.51, 95%CI: 2.09–3.01). Hospital admission rate was positively associated with SUD (IRR = 4.67, 95%CI: 4.28–5.08), dual diagnosis (IRR = 1.83, 95%CI: 1.64–2.04), and psychiatric diagnoses (IRR = 1.73, 95%CI: 1.55–1.92). Days to first hospitalization were negatively associated with SUD (IRR = 0.52, 95%CI: 0.47–0.58), dual diagnosis (IRR = 0.57, 95%CI: 0.50–0.65), and psychiatric diagnoses (IRR = 0.83, 95%CI: 0.73–0.93). The marginal effects of SUD and/or mental disorders increased with age for all outcomes, except for days to first hospitalization.Conclusion: Three of four older persons assessed for substance use severity were later hospitalized. Substance use disorders, dual diagnoses and other mental disorders were the primary reasons for hospitalization and were associated with longer stays, earlier hospitalization, and repeated admissions. Sensitizing service providers to old age substance use and sharing data across the care continuum could provide multiple points of contact to reduce the risk of hospitalizations among older persons with problematic substance use.
