- Background: The purpose of this study is to investigate the impact of oxygen therapy on cardiovascular outcomes in relation to sex in patients with confirmed myocardial infarction (MI).Methods: The DETermination of the role of Oxygen in suspected Acute Myocardial Infarction trial randomized 6,629 patients to oxygen at 6 L/min for 6-12 hours or ambient air. In the present subgroup analysis including 5,010 patients (1,388 women and 3,622 men) with confirmed MI, we report the effect of supplemental oxygen on the composite of all-cause death, rehospitalization with MI, or heart failure at long-term follow-up, stratified according to sex.Results: Event rate for the composite endpoint was 18.1% in women allocated to oxygen, compared to 21.4% in women allocated to ambient air (hazard ratio [HR] 0.83, 95% confidence interval [CI] 0.65-1.05). In men, the incidence was 13.6% in patients allocated to oxygen compared to 13.3% in patients allocated to ambient air (HR 1.03, 95% CI 0.86-1.23). No significant interaction in relation to sex was found (P=.16). Irrespective of allocated treatment, the composite endpoint occurred more often in women compared to men (19.7 vs 13.4%, HR 1.51; 95% CI, 1.30-1.75). After adjustment for age alone, there was no difference between the sexes (HR 1.06, 95% CI 0.91-1.24), which remained consistent after multivariate adjustment.Conclusion: Oxygen therapy in normoxemic MI patients did not significantly affect all-cause mortality or rehospitalization for MI or heart failure in women or men. The observed worse outcome in women was explained by differences in baseline characteristics, especially age

- We study information flows in China's stock markets. By using panel data methods we test for a unit root in the price premium of domestic investors’ A shares over foreign investors’ B shares, as well as cointegration between the A- and B-share prices on the Shanghai and Shenzhen stock exchanges. We find that the A-share premia are nonstationary, and that the A- and B-share prices are not cointegrated up till January 2001. After February 2001, when domestic investors were allowed to trade B shares, the A-share premia become stationary and the A- and B-share prices cointegrated. One interesting result from the panel data analysis is that most firms’ A and B shares are cointegrated, but not all firms. Cointegration is more likely for firms with a small A-share premium, low ratio of nontradeable shares, high growth rate and large B-share market capitalization relative to the A-share market capitalization. Our findings suggest that the relaxation of the investment restrictions decreased the segmentation between the A- and B-share markets in China.

Tidskriftsartikel (refereegranskat)abstract
- This study compared the caring situation, health, self-efficacy, and stress of young (16-25) informal carers (YICs) supporting a family member with mental illness with that of YICs supporting a friend. A sample of 225 carers, assigned to a family group (n = 97) or a friend group (n = 128) completed the questionnaire. It was found that the family group experiences a lower level of support and friends experienced a lower positive value of caring. No other differences in health, general self-efficacy and stress were found. YICs endure different social situations, which is why further study of the needs of YICs, especially those supporting friends, is urgently needed.

- Accessible summary The burden of caring for a person with mental illness has been transferred to families and close friends. Daily life for young informal carers is unpredictable and they need to stay alert and prepared for events beyond their control. Young informal carers are concerned young adults who support a family member or friend unconditionally. Supporting a friend is related to as a great a sense of individual responsibility as supporting a family member. Abstract This study describes the daily life and management strategies of young informal carers of family members or friends with mental illness. Twelve young adults (three men and nine women; 1625 years old) in Sweden were voluntarily recruited between February and May 2008. Data collected through eight individual semi-structured interviews and one focus group interview were analysed using qualitative content analysis. The findings revealed nine subthemes that were further grouped into three main themes: showing concern, providing support and using management strategies. Participants lived in constant readiness for something unexpected to happen to the person they cared for, and their role in the relationship could change quickly from family member or friend to guardian or supervisor. Supporting a friend was considered as large a personal responsibility as supporting a family member. Their management strategies were based on individual capacities and their ability to step aside should the situation become too demanding. These young informal carers need support in caring for the mentally ill. As the internet becomes increasingly fundamental to daily life, support could be provided most effectively through person-centred web sites.

- Objective: Compare the impact of two interventions, a web-based support and a folder support, for young persons who care for people who suffer from mental illness. Methods: This study was a randomized control trial, following the CONSORT statements, which compared the impact of two interventions. Primary outcome variable was stress, and secondary outcome variables were caring situation, general self-efficacy, well-being, health, and quality of life of young informal carers (N= 241). Data were collected in June 2010 to April 2011, with self-assessment questionnaires, comparing the two interventions and also to detect changes. Results: The stress levels were high in both groups at baseline, but decreased in the folder group. The folder group had improvement in their caring situation (also different from the web group), general self-efficacy, well-being, and quality of life. The web group showed increase in well-being. Conclusion: Young informal carers who take on the responsibility for people close to them; suffer consequences on their own health. They live in a life-situation characterized by high stress and low well-being. This signals a need for support. Practice implications: The non-significant differences show that each intervention can be effective, and that it depends upon the individual's preferences. This highlights the importance of adopting person-centered approach, in which young persons can themselves choose support strategy. © 2013 Elsevier Ireland Ltd.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to explore how young (16-25 year old) informal carers of a person with a mental illness experience and use support. In a mixed method approach, we interviewed 12 young carers, and 241 completed a self-administered questionnaire. While the young carers strive to maintain control, their main support seems to be others in their lives, who often define the situation differently. The carers said web-support, counseling, and group counseling might be helpful, yet very few had any professional support. Young carers are greatly in need of support and it should be provided.

- Background: Little is known about whether individuals with autism spectrum disorder (ASD) or attention deficit hyperactive disorder (ADHD) experience any specific facilitators or barriers to driving education.Objective: To explore the facilitators or barriers to driving education experienced by individuals with ASD or ADHD who obtained a learner’s permit, from the perspective of the learner drivers and their driving instructors.Methods: Data were collected from 33 participants with ASD or ADHD, and nine of their driving instructors.Results: Participants with ASD required twice as many driving lessons and more on-road tests than those with ADHD. Participants with ADHD repeated the written tests more than those with ASD. Driving license theory was more challenging for individuals with ADHD, whilst individuals with ASD found translating theory into practice and adjusting to “unfamiliar” driving situations to be the greatest challenges.Conclusion: Obtaining a driving license was associated with stressful training experience.

- Hepatitis B is a well known problem in dialysis units. We therefore examined the historical frequency of hepatitis B carriers in our unit, our vaccination program to hepatitis B virus (HBV), the response to hepatitis B vaccine, the IgG subclass response of anti-HBs and the response and IgG subclass response to pneumococcal vaccination (another vaccine) in dialysis patients. From 1970 and onwards 23 HBV carriers were found, but no new cases of hepatitis B occurred during the study period, i.e. from 1980 and onwards. Only one of the carriers was alive by the end of 2001. In four patients liver disease (in one of them liver cirrhosis) may have been a concomitant cause of death. The antibody response to hepatitis B vaccine was significantly lower in patients than in staff. In four patients a fourth injection was cancelled due to transplantation and bad health, while such data were lacking in 8 cases. In anti-HBs positive patients and controls a significant difference in the response of healthy adults was observed in anti-HBs IgG1 (p < 0.001) vs all other IgG subclasses. Dialysis patients had low levels, or negative findings, in all cases, with IgG1 as the highest proportion found (3/11 patients). An antibody response to pneumococcal vaccination was registered in 25 out of 29 dialysis patients (in all 86%). The IgG-subclass vaccination response to pneumococci in 28 dialysis patients was mainly IgG2 and IgG1 but also occurred in IgG3 and IgG4. Prevaccination antibody levels of the controls were higher in IgG1 and IgG2 (p < 0.01) (n = 21) than in dialysis patients (n = 28). Hepatitis B is nowadays a rare, but still dangerous disease in nephrology units. Dialysis patients have a reduced response to hepatitis B vaccine and vaccination schedules should be started early as some patients otherwise may not receive a fourth injection. The adequate antibody response to pneumococcal vaccination mainly due to IgG2 and IgG1 antibodies indicates that the antigen involved is important in vaccination responses in dialysis patients.

An explorative study on respiratory health among operators working in polymer additive manufacturing
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Additive manufacturing (AM), or 3D printing, is a growing industry involving a wide range of different techniques and materials. The potential toxicological effects of emissions produced in the process, involving both ultrafine particles and volatile organic compounds (VOCs), are unclear, and there are concerns regarding possible health implications among AM operators.The objective of this study was to screen the presence of respiratory health effects among people working with liquid, powdered, or filament plastic materials in AM. MethodsIn total, 18 subjects working with different additive manufacturing techniques and production of filament with polymer feedstock and 20 controls participated in the study. Study subjects filled out a questionnaire and underwent blood and urine sampling, spirometry, impulse oscillometry (IOS), exhaled NO test (FeNO), and collection of particles in exhaled air (PEx), and the exposure was assessed. Analysis of exhaled particles included lung surfactant components such as surfactant protein A (SP-A) and phosphatidylcholines. SP-A and albumin were determined using ELISA. Using reversed-phase liquid chromatography and targeted mass spectrometry, the relative abundance of 15 species of phosphatidylcholine (PC) was determined in exhaled particles. The results were evaluated by univariate and multivariate statistical analyses (principal component analysis). ResultsExposure and emission measurements in AM settings revealed a large variation in particle and VOC concentrations as well as the composition of VOCs, depending on the AM technique and feedstock. Levels of FeNO, IOS, and spirometry parameters were within clinical reference values for all AM operators. There was a difference in the relative abundance of saturated, notably dipalmitoylphosphatidylcholine (PC16:0_16:0), and unsaturated lung surfactant lipids in exhaled particles between controls and AM operators. ConclusionThere were no statistically significant differences between AM operators and controls for the different health examinations, which may be due to the low number of participants. However, the observed difference in the PC lipid profile in exhaled particles indicates a possible impact of the exposure and could be used as possible early biomarkers of adverse effects in the airways.

Dynamics of specific ammonia-oxidizing bacterial populations and nitrification in response to controlled shifts of ammonium concentrations in wastewater
- 2013

Tidskriftsartikel (refereegranskat)abstract
- Ammonia-oxidizing bacteria (AOB) are essential for the nitrification process in wastewater treatment. To retain these slow-growing bacteria in wastewater treatment plants (WWTPs), they are often grown as biofilms, e.g., on nitrifying trickling filters (NTFs) or on carriers in moving bed biofilm reactors (MBBRs). On NTFs, a decreasing ammonium gradient is formed because of the AOB activity, resulting in low ammonium concentrations at the bottom and reduced biomass with depth. To optimize the NTF process, different ammonium feed strategies may be designed. This, however, requires knowledge about AOB population dynamics. Using fluorescence in situ hybridization (FISH) and confocal laser scanning microscopy, we followed biomass changes during 6 months, of three AOB populations on biofilm carriers. These were immersed in aerated MBBR tanks in a pilot plant receiving full-scale wastewater. Tanks were arranged in series, forming a wastewater ammonium gradient mimicking an NTF ammonium gradient. The biomass of one of the dominating Nitrosomonas oligotropha-like populations increased after an ammonium upshift, reaching levels comparable to the high ammonium control in 28 days, whereas a Nitrosomonas europaea-like population increased relatively slowly. The MBBR results, together with competition studies in NTF systems fed with wastewater under controlled ammonium regimes, suggest a differentiation between the two N. oligotropha populations, which may be important for WWTP nitrification.
