Perceptions of everyday life during lenient COVID-19 restrictions in Sweden- an interview study.

Background: Both COVID-19 and its associated societal restrictions have affected individuals' health and everyday life. In Sweden, more lenient public health restrictions were implemented, with individuals asked to act responsibly in terms of reducing spread of disease. The majority of studies reporting on experiences of Covid-19 restrictions have been in the context of more substantial mandatory rules aimed at reducing social contact, therefore it is important to describe how more lenient restrictions have impacted individuals' well-being.

Study protocol for a feasibility study of an online educational programme for people working and living with persistent low back pain.

Background: Low back pain (LBP) is the main cause of activity limitation and work absence across the world, leading to a high social and economic burden for individuals, families, the labour market and society. The overall aim of this multicentre study is to test the usability, acceptability and feasibility of an evidence-based, digital education programme for people living and working with persistent LBP who are in sedentary or physically demanding jobs and need advice on ergonomics, self-management of pain and healthy behavioural strategies.

Methods: This is the protocol of a multinational, multicentre, prospective uncontrolled feasibility study targeting people with persistent LBP in Lithuania, Northern Ireland, Italy, Sweden and Portugal.

Self-Perceived Changes in Physical Activity and the Relation to Life Satisfaction and Rated Physical Capacity in Swedish Adults during the COVID-19 Pandemic-A Cross Sectional Study.

COVID-19 restrictions may prevent people from reaching recommended levels of physical activity (PA). This study examines self-perceived changes in the extent and intensity of PA during the COVID-19 pandemic, and the relation between perceived changes in PA and general life satisfaction and perceived physical capacity. A total of 1318 participants (mean age 47.

Kinesiophobia and its relation to pain characteristics and cognitive affective variables in older adults with chronic pain.

Background: The contribution of kinesiophobia (fear of movement) to the pain experience among older adults has been poorly evaluated. The aim of this study was to study prevalence at baseline, development over a 12-month period and cognitive-affective variables of kinesiophobia in a population-based sample of older adults with chronic pain.

Methods: The study included 433 older adults (+65 years) with chronic pain (mean age 74.

Impact of pain characteristics and fear-avoidance beliefs on physical activity levels among older adults with chronic pain: a population-based, longitudinal study.

Background: To explore the level of physical activity in a population based sample of older adults; to analyze the influence of pain characteristics and fear-avoidance beliefs as predictors of physical activity among older adults reporting chronic pain.

Methods: Demographics, pain characteristics (duration, intensity), physical activity, kinesiophobia (excessive fear of movement/(re) injury), self-efficacy and self-rated health were measured with questionnaires at baseline and 12-months later. Logistic regression analyses were done to identify associations at baseline and predictors of physical activity 12-months later during follow-up.

The ¹³C bicarbonate method: an inverse end product method for measuring CO₂ production and energy expenditure.

We reconsider the principle of the (13)C bicarbonate (NaH(13)CO3) method ((13)C-BM) for the determination of the CO2 production to obtain an estimate of energy expenditure (EE). Its mathematical concept based on a three-compartmental model is related to the [(15)N]glycine end product method. The CO2 production calculated by the (13)C-BM, RaCO2((13)C) is compared to the result from the indirect calorimetry, RCO2(IC).

The oral [(13)C]bicarbonate technique for measurement of short-term energy expenditure of sled dogs and their physiological response to diets with different fat:carbohydrate ratios.

The oral [(13)C]bicarbonate technique (o(13)CBT) was assessed for the determination of short-term energy expenditure (EE) under field conditions. A total of eight Alaskan huskies were fed two experimental diets in a cross-over experiment including two periods of 3 weeks. Effects of diets on EE, apparent total tract digestibility (ATTD) and on plasma hormones, blood lactate and glucose were furthermore investigated.

Evaluation of the oral (13)C-bicarbonate technique for measurements of energy expenditure in dogs before and after body weight reduction.

Background: Overweight and obesity are the most common nutritional disorders in dogs and may lead to various secondary diseases and decreased lifespan. In obesity research, measurement of energy expenditure (EE) and determination of the energy requirements are essential. The objective with this study was to validate and evaluate the suitability of the oral (13)C-bicarbonate technique (o(13)CBT) for measuring EE in dog obesity studies.

The oral (13)C-bicarbonate technique for estimation of energy expenditure in dogs: validation against indirect calorimetry.

To get more knowledge about the energy requirements of dogs and to formulate appropriate feeding guidelines, it is essential to determine their energy expenditure (EE) in a reliable and feasible way. In this study, the non-invasive oral stable isotope (13)C-bicarbonate technique (o(13)CBT) was validated against indirect calorimetry (IC) for the determination of CO2-production and EE in dogs. Eleven privately owned dogs were simultaneously measured with IC and the o(13)CBT after being fasted overnight.

Psychometric properties of the Tampa Scale of Kinesiophobia (TSK-11) among older people with chronic pain.

Objectives: The study aimed to test the construct validity, factor structure and reliability of the 11-item version of the Tampa Scale for Kinesiophobia (TSK-11, Swedish version) among older people (65+) with chronic pain.

Design: Methodological study.

Subjects: 433 participants with chronic pain (mean age 74.

Student learning about biomolecular self-assembly using two different external representations.

Self-assembly is the fundamental but counterintuitive principle that explains how ordered biomolecular complexes form spontaneously in the cell. This study investigated the impact of using two external representations of virus self-assembly, an interactive tangible three-dimensional model and a static two-dimensional image, on student learning about the process of self-assembly in a group exercise. A conceptual analysis of self-assembly into a set of facets was performed to support study design and analysis.

Smoking and chronic pain among people aged 65 years and older.

Objective: To study the relationship between smoking and chronic pain among people aged 65+ years.

Design: A cross-sectional study.

Sample: The study was carried out in 2011 and included a randomly selected (N = 2000, response rate 57%) sample of people aged 65 years and older, living in Sweden.

Metabolic and growth response of mink (Neovison vison) kits until 10 weeks of age when exposed to different dietary protein provision.

Growth performance and metabolism were investigated in mink kits (n = 210) exposed to the same dietary treatment as their dams (n = 30), i.e. high (HP; 61% of metabolisable energy, ME), medium (MP; 48% of ME) or low (LP; 30% of ME) protein supply, from birth until 10 weeks of age.

Evaluation of the oral ¹³C-bicarbonate tracer technique for the estimation of CO₂ production and energy expenditure in dogs during rest and physical activity.

For feeding of working dogs during their daily life, illness, routine jobs or sporting activities, an accurate determination of their nutritional requirements is essential to ensure their optimal health and performance. To predict the appropriate guidelines about how to feed dogs, it appears essential to determine the energy expenditure (EE) in a reliable and feasible way. In the present experiment, the non-invasive oral ¹³C-bicarbonate tracer technique (o¹³CT), i.

Obstetricians' attitudes and opinions on sickness absence and benefits during pregnancy.

Background: In Sweden, sick leave is taken more frequently by pregnant women than by nonpregnant women. This led us to ask if the taking of sick leave during pregnancy could possibly be explained by attitudes to sickness absence held among obstetricians working in antenatal care.

Methods: All obstetricians (n = 45) engaged in public antenatal care and at work in May 2001 in seven hospitals in South Eastern Sweden were asked to anonymously respond to questions/statements concerning their work; 87% participated.

Health, sociodemographic data, and pregnancy outcome in women with antepartum depressive symptoms.

Objective: To study whether women with antepartum depression have an increased risk for adverse perinatal outcome.

Methods: From a sample of 1,489 women, an index group (n = 259) of all women with depressive symptoms on the Edinburgh Postnatal Depression Scale in gestational week 35-36 was selected. Two hundred fifty-nine women with no depressive symptoms on the Edinburgh Postnatal Depression Scale antepartum or postpartum were randomly chosen as the reference group.
