Vocational Rehabilitation after Acquired Brain Injury: A Swedish Study of Benefits and Costs  [PDF]
Kersti Samuelsson, Maria Tropp, Anna Lundqvist
Open Journal of Therapy and Rehabilitation (OJTR) , 2014, DOI: 10.4236/ojtr.2014.23019
Abstract:

Purpose: To examine the benefits from a vocational rehabilitation program for patients suffering from Acquired Brain Injury (ABI) in terms of quality of life, and overall health. In addition, to examine the direct societal costs of healthcare interventions related to vocational rehabilitation and indirect societal costs related to production loss. Method: Identified interventions in 45 patients with ABI who were discharged from a vocational rehabilitation program between 2010 and 2011 were documented, classified and translated into costs. Expenses associated with production loss were calculated by comparing sick leave production loss at first contact with the team, with sick leave production loss at discharge. Health related QoL and overall health, was measured at first contact and at discharge by using the EQ5D. Results: For vocational rehabilitation interventions, mean costs were €6303/individual/month. At first contact with the team, mean production loss was estimated to be €4409/individual/month compared; at discharge to be €2446. QoL ratings increased from first contact to discharge, although estimated health did not change. At discharge, significant correlations were found between QoL ratings and estimated health and the extent of production loss (p < 0.05). Conclusion: Healthcare interventions that help ABI patients resume work are cost effective for society as well as for patients.

Driving after Brain Injury: A Clinical Model Based on a Quality Improvement Project  [PDF]
Anna Lundqvist, Johan Alinder, Ingalill Modig-Arding, Kersti Samuelsson
Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.26094
Abstract: The question of whether a person can resume driving after acquired cognitive dysfunction is raised in primary care services and in hospital departments where patients suffering from brain injury are treated. These organizations rarely have a specialized program that evaluates driving fitness. This article describes a semi-structured and individualized model that serves as clinical guidelines for determining fitness to drive. The model is based on former research and clinical experience. It is exemplified by the procedure of forty-three individuals with congenital or acquired cognitive dysfunction due to head trauma or disease. A multidisciplinary team including medical, neuropsychological, occupational, and practical driving specialists optimised the clinical applicability of a driving assessment using quantitative and qualitative methods. The team discussions, including several professional evaluations and assessments, are considered very important for interpreting results, for understanding whether the cognitive impairments will have consequences on driving, and whether the individual can compensate for cognitive difficulties. The current way to determine a patient’s fitness to drive after cognitive dysfunction is an individually adapted combination of assessment methods that are often performed stepwise. This well-practiced evaluation process reveals that in many cases neither off-road tests nor on-road tests alone are sufficient to ensure sound decisions. To improve on these evaluations, this study concludes that a team-based consensus approach consisting of specialized national teams should be established to support primary care services in assessing fitness to drive in more complicated cases.
Computerized Training of Working Memory for Patients with Acquired Brain Injury  [PDF]
Lovisa Hellgren, Kersti Samuelsson, Anna Lundqvist, Bj?rn B?rsbo
Open Journal of Therapy and Rehabilitation (OJTR) , 2015, DOI: 10.4236/ojtr.2015.32007
Abstract: Background: Patients with acquired brain injury often experience impaired working memory (WM), a condition that can make everyday life activities and work difficult. Objectives: This study investigates the effects of computerized WM training on WM skills, cognitive tests, activity performance and estimated health and whether the effects of computerized WM training can be attributed to sex or time since injury. Methods: Forty-eight patients with acquired brain injury underwent computerized WM training. Patients were tested by a neuropsychologist and interviewed by an occupational therapist just prior and 20 weeks after completion of training. Results: Patients who participated in computerized WM training significantly improved their WM skills shown in WM index, their neuropsychological test scores, and their self-estimated health scores. They also significantly improved their performance of individually defined WM-related everyday activities and their satisfaction with the performance of these activities. There was a significant difference in terms of WM index, WM-related daily activity performance, and satisfaction with respect to time since injury. Conclusion: Computerized WM training can improve cognitive and everyday performance for patients with acquired brain injury. Patients can improve their cognitive functions a long time after suffering a brain injury or disease. This effect is greater if WM training is used early in the rehabilitation.
Mindfulness and Aerobic Exercise as an Intervention for Cognitive Dysfunction Following an Acquired Brain Injury: A Pilot Study  [PDF]
Lovisa Hellgren, Anna Lundqvist, Bj?rn B?rsbo, Richard Levi, Kersti Samuelsson
Open Journal of Therapy and Rehabilitation (OJTR) , 2019, DOI: 10.4236/ojtr.2019.71002
Abstract: Background: Cognitive impairments as sequelae of brain injury are common and can negatively affect activities of everyday life, participation and quality of life. Thus, finding ways to reduce cognitive impairments and ameliorate their negative impact on everyday life is an important focus of research. Aim: The aim of this pilot study was to analyse the effects of a combination of guided mindfulness and aerobic exercise on cognitive ability and mental fatigue in patients with acquired brain injury (ABI). Design: Pilot study, with a before-after design. Setting: Outpatient. Population: Twenty-one patients suffering from ABI, former patients of three rehabilitation medicine departments. Methods: The intervention comprised a structured combination of guided mindfulness program and outdoor walking, three times/week for 12 weeks. The outcome measures included assessment of information processing speed, working memory, oxygen uptake and self-reported mental fatigue. Results: The main results showed improvements in cognitive abilities related to information processing speed, perceived mental fatigue and physical capacity. Conclusions: A combination of mindfulness and physical activity can increase information processing speed and ameliorate mental fatigue. Further studies are needed to confirm our findings. Clinical Rehabilitation Impact: The combination of guided mindfulness and physical activity shows promise as a treatment modality in rehabilitation of impaired information processing speed and mental fatigue following ABI.
Parents' experiences of an abnormal ultrasound examination - vacillating between emotional confusion and sense of reality

Reproductive Health , 2010, DOI: 10.1186/1742-4755-7-10
Abstract: Sixteen parents, mothers and fathers, whose fetus had been diagnosed with an abnormality during an ultrasound scan in the second or third trimester, were interviewed. The study employed a grounded theory approach.The core category vacillating between the emotional confusion and sense of reality is related to the main concern assessment of the diagnosis impact on the well-being of the fetus. Two other categories Entering uncertainty and Involved in an ongoing change and adaptation have each five sub-categories.Parents are aware of that ultrasound examination is a tool for identifying abnormalities prenatally. The information about the abnormality initially results in broken expectations and anxiety. Parents become involved in ongoing change and adaptation. They need information about the ultrasound findings and the treatment without prolonged delay and in a suitable environment. The examiner who performs the ultrasound examination must be aware of how anxiety can be intensified by environmental factors. All parents should to be offered a professional person to give them support as a part of the routine management of this situation.Major fetal abnormalities are often detected by a prenatal ultrasound examination [1]. According to a Swedish population-based study from 2006, the prevalence of diagnosed malformations was 2.6% with one routine ultrasound screening [2]. Levi [3] showed in a review of available studies that in specialist centres the detection rate of fetal abnormalities ranges from 80% to 95%. When the ultrasound examination reveals abnormal findings, it is a shock for the parents-to-be as found in a systematic review from 2002 [4]. Women often experience emotional reactions such as anxiety, prostration, depression, and loneliness [5], as well as guilt, fear, sadness or hopelessness. Women also begin grieving at the time of the fetal ultrasound examination while men experience anger and anxiety [6] and both of the parents experience the emotions of anxiety,

Flash ionization of the partially ionized wind of the progenitor of SN 1987A
Peter Lundqvist
Physics , 1998, DOI: 10.1086/306654
Abstract: The H II region created by the progenitor of SN 1987A was further heated and ionized by the supernova flash. Prior to the flash, the temperature of the gas was 4000 - 5000 K, and helium was neutral, while the post-flash temperature was only slightly less than 10^5 K, with the gas being ionized to helium-like ionization stages of C, N and O. We have followed the slow post-flash cooling and recombination of the gas, as well as its line emission, and find that the strongest lines are N V 1240 and O VI 1034. Both these lines are good probes for the density of the gas, and suitable instruments to detect the lines are STIS on HST and FUSE, respectively. Other lines which may be detectable are N IV] 1486 and [O III] 5007, though they are expected to be substantially weaker. The relative strength of the oxygen lines is found to be a good tracer of the color temperature of the supernova flash. From previous observations, we put limits on the hydrogen density, n_H, of the H II region. The early N V 1240 flux measured by IUE gives an upper limit which is n_H ~ 180 \eta^{-0.40} cm^{-3}, where \eta is the filling factor of the gas. The recently reported emission in [O III] 5007 at 2500 days requires n_H = (160\pm12) \eta^{-0.19} cm^{-3}, for a supernova burst similar to that in the 500full1 model of Ensman & Burrows (1992). For the more energetic 500full2 burst the density is n_H = (215\pm15) \eta^{-0.19} cm^{-3}. These values are much higher than in models of the X-ray emission from the supernova (n_H ~ 75 cm^{-3}), and it seems plausible that the observed [O III] emission is produced primarily elsewhere than in the H II region. We also discuss the type of progenitor consistent with the H II region. In particular, it seems unlikely that its spectral type was much earlier than B2 Ia.

Boolean ideals and their varieties
Samuel Lundqvist
Mathematics , 2012,
Abstract: We consider ideals in the ring $\mathbb{Z}_2[x_1,\ldots, x_n]$ that contain the polynomials $x_i^2 - x_i$ for $i = 1, \ldots, n$ and give various results related to the one-to-one correspondence between these ideals and the subsets of $\mathbb{Z}_2^n$. We also study the standard monomials with respect to the lexicographical ordering for these ideals and derive a distribution result.
A local duality principle for ideals of pure dimension
Johannes Lundqvist
Mathematics , 2013,
Abstract: We prove that a certain cohomological residue associated to an ideal of pure dimension is annihilated exactly by the ideal. The cohomological residue is quite explicit and generalizes the classical local Grothendieck residue and the cohomological residue of Passare.
