Predictors of post-COVID-19 and the impact of persistent symptoms in non-hospitalized patients 12 months after COVID-19, with a focus on work ability.

Background: Better knowledge of long-term symptoms following coronavirus disease 2019 (COVID-19), the so-called post-COVID-19, in non-hospitalized patients is needed. The aim of this study was to study persisent symptoms up to 12 months after COVID-19 in non-hospitalized patients and their impact on work ability. We also investigated predictors of persistent symptoms.

Patterns and predictors of sick leave among Swedish non-hospitalized healthcare and residential care workers with Covid-19 during the early phase of the pandemic.

Healthcare and residential care workers represent two occupational groups that have, in particular, been at risk of Covid-19, its long-term consequences, and related sick leave. In this study, we investigated the predictors of prolonged sick leave among healthcare and residential workers due to non-hospitalized Covid-19 in the early period of the pandemic. This study is based on a patient register (n = 3209) and included non-hospitalized healthcare or residential care service workers with a positive RT- PCR for SARS-CoV-2 (n = 433) between March and August 2020.

A supportive climate and low strain promote well-being and sustainable working life in the operation theatre.

Background: Shortage of health-care workers e.g. in operating theatres is a global problem.

Sickness absence at a young age and later sickness absence, disability pension, death, unemployment and income in native Swedes and immigrants.

Background: Sickness absence with cash benefits from the sickness insurance gives an opportunity to be relieved from work without losing financial security. There are, however, downsides to taking sickness absence. Periods of sickness absence, even short ones, can increase the risk for future spells of sickness absence and unemployment.

Working conditions, serotonin transporter gene polymorphism (5-HTTLPR) and anxiety disorders: a prospective cohort study.

Background: The etiology and pathology of anxiety disorders involve both genetic and environmental influences. Adverse working conditions may contribute to the development of anxiety. The serotonin transporter-linked polymorphic region (5-HTTLPR) has been implicated in stress sensitivity.

Country of birth-specific and gender differences in prevalence of diabetes in Sweden.

Objective: The aim was to investigate country or region of birth-specific prevalence and gender differences of diabetes in residents in Sweden, using Swedish-born men and women as referent.

Methods: The Apolipoprotein MOrtality RISk (AMORIS) cohort was used (184,000 men and 151,453 women) aged between 20 and 80 years, with data from the CALAB laboratory, Stockholm, 1985-1996. Diabetes was defined as fasting glucose ≥ 7.

Unemployment at a young age and later sickness absence, disability pension and death in native Swedes and immigrants.

Background: Youth unemployment is an increasing problem for societies around the world. Research has revealed negative health effects of unemployment, and this longitudinal register-based cohort study examined the relationship between unemployment and later sickness absence, disability pension and death among youth in Sweden.

Method: The study group of 199,623 individuals comprised all immigrants born between 1968 and 1972 who immigrated before 1990 (25,607) and a random sample of native Swedes in the same age-range (174,016).

Dyslipidemia is a strong predictor of myocardial infarction in subjects with chronic kidney disease.

Aim: To evaluate dyslipidemia as predictor of myocardial infarction (MI) in subjects with or without chronic kidney disease (CKD).

Methods: In 142,394 middle-aged Swedes referred for laboratory evaluation, glomerular filtration rates (GFR) were estimated using the Modification of Diet in Renal Disease study equation. CKD was defined as GFR 15-60 mL/min/1.

Improved survival after coronary artery bypass grafting has not influenced the mortality disadvantage in patients with diabetes mellitus.

Objectives: We sought to compare mortality after coronary artery bypass grafting in patients with and without diabetes mellitus undergoing operations during different time periods.

Methods: We performed analyses of 12,415 primary isolated coronary artery bypass grafting operations performed during 1970-2003, with follow-up of 5-year mortality up to December 2006.

Results: The prevalence of diabetes mellitus continuously increased up to 25% among patients undergoing coronary artery bypass grafting in 2003.

Cervical, endometrial and ovarian cancers among immigrants in Sweden: importance of age at migration and duration of residence.

In order to compare the risk of gynaecologic cancer among foreign-born women to the risk among those born in Sweden and to elucidate risk of cancer in relation to age at migration and duration of residence, we followed a cohort of 5.3 million women between 1969 and 2004 in Sweden. Through linkage with the national cancer register, we estimated cancer risk as rate ratios (RRs) with 95% confidence intervals (CIs) using Poisson regression.

Grade of left main coronary artery stenosis does not influence long-term mortality after coronary artery bypass surgery.

Objective: To assess if grade of left main coronary artery (LMCA) stenosis influences early or long-term mortality after coronary artery bypass grafting (CABG).

Design: Among all 1 384 patients with LMCA stenosis at Karolinska Hospital, Stockholm, Sweden during 1990-1999, 131 deaths occurred within 5 years of surgery (cases). Matched controls (n=146) were randomly selected from all surviving LMCA patients taking gender, age and year of surgery into account.

Elevated glycosylated haemoglobin (HbA1c) is a risk marker in coronary artery bypass surgery.

Objective: To evaluate if glycosylated haemoglobin 1 (HbA1c) was associated with increased risk of infection and mortality after coronary artery bypass grafting (CABG).

Design: Prospective observational study. Preoperative HbA1c concentrations were correlated to outcome in patients followed for an average of 3.

Associations between parents' and 12-year-old children's sport and vigorous activity: the role of self-esteem and athletic competence.

Background: The aims of this study were to investigate parent-child physical activity (PA) associations and whether children's self-esteem or athletic competence mediates such associations.

Methods: The study population comprised 1124 12-year-old children and their parents. Parents' PA was assessed using the Baecke questionnaire and a question about sport participation.

Risk of thyroid cancer among Iranian immigrants in Sweden.

Objectives: Studies of immigrants are of value to elucidate the role of environmental factors in cancer causation, but large cohorts are needed in order to study rare cancers. We conducted a register-based study of a cohort of 59,274 (32,236 men and 27,038 women) Swedish residents born in Iran, with follow-up between 1969 and 2004. We identified 50 incident cases of thyroid cancer during more than 800 thousands person-years of observation.

Renal insufficiency and long-term mortality and incidence of myocardial infarction in patients undergoing coronary artery bypass grafting.

Aims: To evaluate the impact of renal insufficiency (RI) on long-term mortality and incident myocardial infarction (MI) in patients undergoing coronary artery bypass grafting (CABG).

Methods And Results: All patients (n = 6575) without dialysis-dependent RI undergoing a first isolated CABG during 1980-1995 at the Karolinska hospital who survived 30 days post-operatively were included. Estimated glomerular filtration rate (eGFR) was related to the incidence of MI and all-cause mortality within 5 years.

Risk of death or acute myocardial infarction 10 years after coronary artery bypass surgery in relation to type of diabetes.

Background: The aim of this study was to assess the long-term risk of death or acute myocardial infarction (AMI) in patients with diabetes mellitus (DM) compared with that in patients without DM after coronary artery bypass grafting (CABG).

Methods: National registers were used to record death or AMI occurring in 6727 patients who had CABG during 1980 to 1995. Diabetes mellitus in 856 patients (13%) was classified as type 1 (6%) or type 2 treated with insulin (29%), oral drugs (46%), or diet (19%).

High mortality after coronary bypass surgery in patients with high-grade left main coronary artery stenosis.

Objective: To determine mortality after coronary artery bypass grafting (CABG) in relation to degree of left main coronary artery (LMCA) obstruction.

Design: All patients without LMCA stenosis (n=3370), with low-grade stenosis (n = 261), high-grade stenosis (n = 224) or total occlusion of the LMCA (n = 15) were followed for ten years after CABG performed during 1970-1989.

Results: Early mortality was 1.

Changes in shape and location of BMI distributions of Swedish children.

Aims: One aim was to disentangle how the shape and location of the BMI distribution changed among Swedish children over a 12 y period. Another aim was to identify the age during childhood when changes occurred or became manifest.

Methods: Two population-based cohorts-2,591 children from Stockholm born 1985-1987 and 3,650 from Gothenburg born 1973-1975-were compared with respect to BMI distributions from 2 to 15 y of age.
