- Background Low income and short education have been found to be independently associated with inferior survival after coronary artery bypass grafting (CABG), whereas the use of secondary prevention medications is associated with improved survival. We investigated whether underusage of secondary prevention medications contributes to the inferior long-term survival in CABG patients with a low income and short education. Methods and Results Patients who underwent CABG in Sweden between 2006 to 2015 and survived at least 6months after discharge (n=28448) were included in a population-based cohort study. Individual patient data from 5 national registries, including the SWEDEHEART (Swedish Web System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies) registry, covering dispensing of secondary prevention medications (statins, platelet inhibitors, β-blockers, and RAAS inhibitors), socioeconomic factors, patient characteristics, comorbidity, and long-term mortaity were merged. All-cause mortality risk was estimated using multivariable Cox regression models adjusted for patient characteristics, baseline comorbidities, time-updated secondary prevention medications, and socioeconomic status. Long-term mortality was higher in patients with a low income and short education. Statins and platelet inhibitors were dispensed less often to patients with a low income, both at baseline and after 8years. The decline in dispensing over time was steeper for low-income patients. Short education was not associated with reduced dispensing of any secondary prevention medication. Use of statins (adjusted hazard ratio=0.57 [95% CI, 0.53-0.61]), RAAS inhibitors (adjusted hazard ratio=0.78 [0.73-0.84]), and platelet inhibitors (adjusted hazard ratio=0.74 [0.68-0.80]) were associated with reduced long-term mortality irrespective of socioeconomic status. Conclusions Secondary prevention medications are dispensed less often after CABG to patients with low income. Underusage of secondary prevention medications after CABG is associated with increased mortality risk independently of income and extent of education.

- Background To examine the incidence of atrial fibrillation in individuals with type 2 diabetes compared with age- and sex-matched controls from the general population and its variation in relation to glycaemic control and renal function. Methods A total of 421,855 patients with type 2 diabetes from the Swedish National Diabetes Registry and 2,131,223 controls from the Swedish Population Registry, matched for age, sex and county, were included and followed from January 1, 2001 to December 31, 2013. Results Overall, 8.9% of individuals with type 2 diabetes and 7.0% of controls were diagnosed with atrial fibrillation during follow-up, unadjusted incidence risk ratio (IRR) 1.35 (95% 1.33-1.36). Women < 55 years old with type 2 diabetes had an IRR of 2.36 (95% CI 2.10-2.66), in relation to controls, whereas the corresponding value for men < 55 years old with type 2 diabetes was IRR 1.78 (95% CI 1.67-1.90). In the fully adjusted Cox regression, the risk of type 2 diabetes on incident atrial fibrillation was 28% greater vs controls, hazard ratio (HR) 1.28 (95% CI 1.26-1.30), p < 0.0001. The excess risk of atrial fibrillation in individuals with type 2 diabetes increased with worsening glycaemic control and renal complications. For individuals with HbA1c <= 6.9% (<= 52 mmol/mol) and normoalbuminuria the excess risk vs controls was still increased, adjusted HR 1.16 (95% CI 1.14-1.19); p < 0.0001. Conclusions Individuals with type 2 diabetes had an overall 35% higher risk of atrial fibrillation compared to age- and sex-matched controls from the general population. The excess risk for atrial fibrillation increased with renal complications or with poor glycaemic control. Individuals with type 2 diabetes with good glycaemic control and normoalbuminuria had slightly increased risk.

- Background: It remains unclear whether readmissions of patients with heart failure (HF) have decreased over time in an era of improved therapy and management of HF. This study aimed to determine the temporal short- and long-term trends of cause-specific rehospitalization and their risk factors in a Swedish context. Methods: HF patients in the Swedish Heart Failure Registry (SwedeHF) were investigated. Maximum follow-up time was 1 year. Outcomes included the first occurrence of all-cause, cardiovascular (CV) and HF rehospitalizations. Cox proportional hazards models were performed to determine the impact of increasing years on risk for rehospitalization and its known risk factors. Results: Totally, 25,644 index-hospitalized HF patients in SwedeHF from 2004 to 2011 were enrolled in the study. For 8 years, the incidence risk of 1-year all-cause rehospitalization remained unchanged, whereas the incidence risk of CV (P = 0.038) or HF (P = 0.0038) rehospitalization decreased. After adjustment for age and sex, a 3% decrease per every second year was observed for 1-year CV and HF rehospitalizations (P < 0.05). However, time to the first occurring all-cause, CV and HF rehospitalization did not change significantly from 2004 to 2011 (P-values 0.13-0.87). When two study periods (2004-2005 vs. 2010-2011) were compared, the risk factor profile for rehospitalization was found to change. Conclusions: Throughout the 8-year study period, CV- and HF-related rehospitalizations decreased, whereas all-cause rehospitalization remained unchanged, indicating a parallel increase in non-CV rehospitalization in the HF patients.

- Aim Extrauterine growth restriction is common among extremely preterm infants. We explored whether intake of unpasteurised maternal milk (MM) and pasteurised donor milk (DM) was associated with longitudinal growth outcomes and neonatal morbidities in extremely preterm infants. Methods Observational study of 90 preterm infants born between 2013 and 2015 in Gothenburg, Sweden. Data were prospectively collected on nutritional and breast milk intakes during the first 28 days. Results Ninety infants (39 girls and 51 boys) with a median gestational age of 25.3 (22.7-27.9) weeks were evaluated. MM intake (mL/kg/d) correlated positively with almost all z-scores for weight, length and head circumference at 28 postnatal days and at postmenstrual age (PMA) 32 and 36 weeks. After multivariable adjustment, MM intake and weight z-score at 28 postnatal days and at PMA 32 and 36 weeks remained significantly associated. Infants consuming >= 80% MM had more favourable weight z-scores at PMA 32 and 36 weeks. Intake of DM did not correlate with any growth outcomes. Infants without retinopathy of prematurity had a significantly higher intake of MM (mL/kg/d). Conclusion Unpasteurised MM was positively associated with longitudinal growth outcomes. Motivating mothers to provide their infants with their own milk after preterm birth should be emphasised.

- Importance: To prevent blindness, repeated infant eye examinations are performed to detect severe retinopathy of prematurity (ROP), yet only a small fraction of those screened need treatment. Early individual risk stratification would improve screening timing and efficiency and potentially reduce the risk of blindness. Objectives: To create and validate an easy-to-use prediction model using only birth characteristics and to describe a continuous hazard function for ROP treatment. Design, Setting, and Participants: In this retrospective cohort study, Swedish National Patient Registry data from infants screened for ROP (born between January 1, 2007, and August 7, 2018) were analyzed with Poisson regression for time-varying data (postnatal age, gestational age [GA], sex, birth weight, and important interactions) to develop an individualized predictive model for ROP treatment (called DIGIROP-Birth [Digital ROP]). The model was validated internally and externally (in US and European cohorts) and compared with 4 published prediction models. Main Outcomes and Measures: The study outcome was ROP treatment. The measures were estimated momentary and cumulative risks, hazard ratios with 95% CIs, area under the receiver operating characteristic curve (hereinafter referred to as AUC), sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). Results: Among 7609 infants (54.6% boys; mean [SD] GA, 28.1 [2.1] weeks; mean [SD] birth weight, 1119 [353] g), 442 (5.8%) were treated for ROP, including 142 (40.1%) treated of 354 born at less than 24 gestational weeks. Irrespective of GA, the risk for receiving ROP treatment increased during postnatal weeks 8 through 12 and decreased thereafter. Validations of DIGIROP-Birth for 24 to 30 weeks' GA showed high predictive ability for the model overall (AUC, 0.90 [95% CI, 0.89-0.92] for internal validation, 0.94 [95% CI, 0.90-0.98] for temporal validation, 0.87 [95% CI, 0.84-0.89] for US external validation, and 0.90 [95% CI, 0.85-0.95] for European external validation) by calendar periods and by race/ethnicity. The sensitivity, specificity, PPV, and NPV were numerically at least as high as those obtained from CHOP-ROP (Children's Hospital of Philadelphia-ROP), OMA-ROP (Omaha-ROP), WINROP (weight, insulinlike growth factor 1, neonatal, ROP), and CO-ROP (Colorado-ROP), models requiring more complex postnatal data. Conclusions and Relevance: This study validated an individualized prediction model for infants born at 24 to 30 weeks' GA, enabling early risk prediction of ROP treatment based on birth characteristics data. Postnatal age rather than postmenstrual age was a better predictive variable for the temporal risk of ROP treatment. The model is an accessible online application that appears to be generalizable and to have at least as good test statistics as other models requiring longitudinal neonatal data not always readily available to ophthalmologists.

- Background: Computed tomography (CT) is used to monitor progression of structural lung disease (SLD) in children with cystic fibrosis (CF). Our goals were to identify the risk factors for the annual progression of SLD and the impacts of airway pathogens on SLD. Method: Seventy-five school-aged children diagnosed with CF underwent 200 CT scans at Gothenburg CF Centre in the period 2003–2015. SLD was evaluated with a quantitative scoring system. Mixed models were used to calculate the yearly progression rates of SLD and FEV1 and to analyse the effects of common airway pathogens in CF. Results: The yearly mean progression (95% CI) rates for total disease (%Dis), bronchiectasis (%Be), and FEV1 were 0.62 (0.38–0.86), 0.43 (0.28–0.58) and −0.16 (−0.18–0.13), respectively. Adjusting for airway pathogens, the yearly mean progression rates for %Dis, %Be and FEV1 were 0.23 (−0.04–0.51), 0.12 (0.00–0.25), and −0.12 (−0.16–0.08), respectively. A single infection with P aeruginosa was associated with significant increase in lung damage, assessed as %Dis (p = 0.044) and%Be (p = 0.0047), but not in FEV1 (p = 0.96). At age of 7 years, there was a good correlation between the extent of SLD and subsequent progression of %Dis (r = 0.63, p = 0.0042) and %Be (r = 0.74, p = 0.0057) while there was no significant correlation between the FEV1 and the rate of decline of FEV1 (r = −0.22, p = 0.12). Conclusion: Intermittent respiratory infections with P aeruginosa were associated with significant SLD but no change in FEV1. More SLD at the age of 7 years signals a higher progression rate of SLD subsequently.
