The Swedish National Inpatient Register (IPR), also called the Hospital Discharge Register, is a principal source of data for numerous research projects. IPR part Patient Register. was launched in 1964 (psychiatric diagnoses from 1973) but complete coverage did not begin until 1987. Currently, more than 99% all somatic (including surgery) and psychiatric hospital discharges are registered IPR. A previous validation by Board Health Welfare showed that 85-95% valid. current paper describes...

The risk for sight-threatening retinopathy of prematurity is predicted by using gestational age and/or weight at birth. All infants below a threshold undergo serial ophthalmologic examinations identification those who would benefit from treatment (approximately 10%). We hypothesized that factoring in postnatal gain could identify children more specifically and earlier.Weekly weights birth to postmenstrual week 36 were retrospectively entered into surveillance system gave an alarm when the...

Abstract Context: Craniopharyngiomas (CPs) in adults have been associated with excess mortality. Objective: The aim of the study was to investigate mortality and morbidity patients childhood-onset adult-onset CP.

Patients with hypopituitarism of various etiologies have excess mortality. The mortality in patients nonfunctioning pituitary adenoma (NFPA), regardless function, is less well studied.Our aim was to investigate NFPA and examine whether age at diagnosis, gender, tumor treatments, or hormonal deficiencies influence the outcome.NFPA were identified followed up nationwide health registries Sweden, 1987-2011. criteria for identification tested validated a subpopulation patients.This nationwide,...

We have constructed a reference model to facilitate comparison of serum IGF-I values among children, and thereby improve the value measurements for diagnosis. The data set consists measured in 969 samples from 468 healthy children adolescents (232 males, 236 females; ages, 1.1–18.3 yr). One sample per child was used model, each being selected so as provide sufficient observations stage puberty. not were validate data. log transformed, multiple regression analysis model-building process. best...

Methods cohort consisted of 2354 shiftworkers 3088 dayworkers in two pulp paper manufacturing plants. was monitored 1 January 1952 to 31 December 2001 by linkage national Cause Death Register. Groups workers defined different durations exposure were compared with calculating standardized relative rates (SRR). Results due...

BackgroundThere are few studies on predictors of smoking cessation in general populations. We studied the rate relation to several potential predictors, with special focus respiratory and cardiovascular disease.MethodsSmokers (n = 4636) from seven centres Northern Europe, born between 1945 1973, who answered a questionnaire 1999–2001 (the RHINE study) were followed up new 2010–2012. Altogether 2564 provided complete data smoking. Cox regression analyses performed calculate hazard ratios...

Perfluorinated substances (PFAS) are chemicals with endocrine disruptive properties that may interfere the female reproductive system. However, few studies have explored association between benign gynecological diseases and high PFAS exposure.The aim of this study was to investigate possible associations exposure subsequent diagnosis polycystic ovarian syndrome (PCOS), uterine leiomyoma (fibroids), endometriosis in a cohort exposed through drinking water.In 2013, levels (with sum above...

Objectives:In a large population-based study among adults in northern Europe the relation between occupational exposure and new-onset asthma was studied.

Objectives We aimed to update an asthmagen job exposure matrix (JEM) developed in the late 1990s. Main reasons were: number of suspected and recognised asthmagens has since tripled; understanding aetiological role irritants asthma methodological insights application JEMs have emerged period. Methods For each agent new occupational asthma-specific JEM (OAsJEM), a working group three experts out eight evaluated for International Standard Classification Occupations, 1988 (ISCO-88) code into...

Five thousand one hundred and forty questionnaires concerning leg ulcers were sent to a randomly selected population aged 65 years older in Gothenburg April 1989. The response rate was 89%. Ninety-seven individuals answered affirmatively, that they had ulcers, which corresponds prevalence of 2.15 +/- 0.42 per cent. These 97 the same number controls asked come for medical examination with tests peripheral circulation an interview. Seventy-five (of 97) examined. Thirty-five or foot caused by...

The aim of the present study was to investigate whether repeated peak exposure (gassings) sulphur dioxide (SO 2 ) and other irritant gases increases risk new-onset asthma. A questionnaire sent 4,112 sulphite workers, whom 1,919 completed 396 short-form questionnaire, which out as a last reminder. sample 130 nonrespondents telephone interview using questionnaire. incidence adult-onset, physician-diagnosed asthma during employment duration analysed in relation SO gassings giving rise...

Environmental noise is a growing and well recognized health problem. However, in many cases people are exposed not to single source—for example, road, railway, or aircraft noise—but combination of exposures there only limited knowledge the effects on exposure combined sources. A socio-acoustic survey among 1953 persons aged 18–75 years was conducted residential areas railway road traffic with sound levels ranging from LAeq,24h 45–72dB municipality east Gothenburg, Sweden. The objectives were...

Objective Hypopituitarism has been associated with increased mortality. The excess mortality may be due to untreated growth hormone (GH) deficiency but also various underlying disorders. We therefore analysed in patients only one disorder, non-functioning pituitary adenoma (NFPA), and without GH replacement therapy (GHRT). Design method Patients NFPA the western region of Sweden, 1997–2011, were identified through National Patient Registry cross-referenced several Health Registries. All...

Objectives The aims were to investigate whether occupational noise increased the risk for coronary heart disease (CHD) and stroke elucidate interactions with stressful working conditions in a cohort of Swedish men. Design This is prospective study on CHD men followed until death, hospital discharge or 75 years age, using national registers cause death discharges. Baseline data occupation from 1974 1977 used classification levels job demand-control. Cox regression was analyse HRs stroke....

Asthma is a prevalent chronic disease and occupation contributes to approximately 15 % of cases among adults. However, there are still few studies on risk factors for work-exacerbated asthma. The current study investigated the association between asthma exacerbations occupational exposures. comprised all currently working adults (n = 1356) who reported ever in prior population-based cohorts. All subjects completed questionnaire about exposures, occupations Exposure high low molecular weight...

To study respiratory effects of exposure to soft paper dust exposure, a relationship that is rarely studied. Soft tissue mill workers at Swedish were investigated using questionnaire and lung function atopy screening. Spirometry without bronchodilation was performed with dry wedge spirometer, forced vital capacity (FVC) expiratory volume in 1 s (FEV1) obtained expressed as percent predicted. Exposure assessed from historical stationary personal measurements total dust, addition information...
