OBJECTIVE: To test if knowledge of type 2 diabetes genetic variants improves disease prediction. RESEARCH DESIGN AND METHODS: We tested 40 single nucleotide polymorphisms (SNPs) associated with ...diabetes in 3,471 Framingham Offspring Study subjects followed over 34 years using pooled logistic regression models stratified by age (<50 years, diabetes cases = 144; or ≥50 years, diabetes cases = 302). Models included clinical risk factors and a 40-SNP weighted genetic risk score. RESULTS: In people <50 years of age, the clinical risk factors model C-statistic was 0.908; the 40-SNP score increased it to 0.911 (P = 0.3; net reclassification improvement (NRI): 10.2%, P = 0.001). In people ≥50 years of age, the C-statistics without and with the score were 0.883 and 0.884 (P = 0.2; NRI: 0.4%). The risk per risk allele was higher in people <50 than ≥50 years of age (24 vs. 11%; P value for age interaction = 0.02). CONCLUSIONS: Knowledge of common genetic variation appropriately reclassifies younger people for type 2 diabetes risk beyond clinical risk factors but not older people.
To describe trends from 2001 to 2015 in incidence and in-hospital outcomes of patients suffering or not suffering from COPD who had undergone lung transplantation (LTx) in Spain.
We used the Spanish ...National Hospital Discharge Database to select all admissions for LTx. Incidence was estimated overall and according to the presence of COPD. Outcomes included infections, complications, length of hospital stay and in-hospital mortality (IHM).
We identified 2,896 admissions for LTx. Admission rates rose in COPD sufferers and non-COPD sufferers over time, with higher rates among COPD patients. COPD and non-COPD patients were older, but mean age was higher in COPD patients. Although there was a male predominance among patients, the proportion of women significantly increased over time in the COPD population. COPD patients had lower Charlson Comorbidity Index values than non-COPD patients (score ≥1, 25.83% and 31.6%,
<0.05). We observed a significant increase in infections and complications of LTx or rejection for both groups over time. IHM decreased from 2001 to 2015 in both groups of patients. COPD was a predictor of lower IHM (OR 0.75, 95% CI 0.61-0.93) after LTx.
LTx-incidence rates were higher in COPD patients and increased over the study period in both groups. The proportion of women significantly increased over time among COPD sufferers. IHM decreased from 2001 to 2015 in both groups of patients. COPD was a predictor of lower mortality during admissions for LTx.
Abstract Aim To describe trends in the incidence and outcomes of community-acquired pneumonia (CAP) hospitalizations in Spain (2004–2013). Methods We used national hospital discharge data to select ...all hospital admissions for CAP as primary diagnosis. We analyzed incidence, Charlson comorbidity index (CCI), diagnostic and therapeutic procedures, pathogens, length of hospital stay (LOHS), in-hospital mortality (IHM) and readmission. Results We identified 959,465 admissions for CAP. Incidence rates of CAP increased significantly over time (from 142.4 in 2004 to 163.87 cases per 100,000 inhabitants in 2013). Time trend analyses showed significant increases in the number of comorbidities and the use of CAT of thorax, red cell transfusion, non-invasive mechanical ventilation and readmissions (all p values < 0.05). S. pneumoniae was the most frequent causative agent, but its isolation decreased over time. Overall median of LOHS was 7 days and it did not change significantly during the study period. Time trend analyses also showed significant decreases in mortality during admission for CAP. Factor associated with higher IHM included: older age, higher CCI, S. aureus isolated, use of red cell transfusion or mechanical ventilation and readmission. Conclusions The incidence and mortality of CAP have changed in Spain from 2004 to 2013. Although there was an increased incidence of hospitalization for this disease over time, we saw a significant reduction in IHM.
(1) Background: We aimed to assess the effect of COPD in the incidence of hospital admissions for COVID-19 and on the in-hospital mortality (IHM) according to sex. (2) Methods: We used national ...hospital discharge data to select persons aged ≥40 years admitted to a hospital with a diagnosis of COVID-19 in 2020 in Spain. (3) Results: The study population included 218,301 patients. Age-adjusted incidence rates of COVID-19 hospitalizations for men with and without COPD were 10.66 and 9.27 per 1000 persons, respectively (IRR 1.14; 95% CI 1.08−1.20; p < 0.001). The IHM was higher in men than in women regardless of the history of COPD. The COPD was associated with higher IHM among women (OR 1.09; 95% CI 1.01−1.22) but not among men. The COPD men had a 25% higher risk of dying in the hospital with COVID-19 than women with COPD (OR 1.25, 95% CI 1.1−1.42). (4) Conclusions: Sex differences seem to exist in the effect of COPD among patients suffering COVID-19. The history of COPD increased the risk of hospitalization among men but not among women, and COPD was only identified as a risk factor for IHM among women. In any case, we observed that COPD men had a higher mortality than COPD women. Understanding the mechanisms underlying these sex differences could help predict the patient outcomes and inform clinical decision making to facilitate early treatment and disposition decisions.
BACKGROUND: This study aimed to compare the rates of open and laparoscopic cholecystectomies and outcomes in patients with or without type 2 diabetes mellitus (T2DM) in Spain from 2003 to 2013. ...METHODS: We collected all cases of open and laparoscopic cholecystectomies using national hospital discharge data and evaluated the annual cholecystectomy rates stratiifed by T2DM status. We analyzed tendency for in-hospital mortality (IHM). We also analyzed the impact of T2DM on IHM in patients who underwent cholecystectomies. RESULTS: We identiifed 611 533 cholecystectomies (71.3%laparoscopic) in the patients, in whom 78 227 (12.8%) patients had T2DM. The rates of open cholecystectomies were 3-fold higher (130.0/105 vs 41.1/105) in patients with T2DM than in those without T2DM, and the rate of laparoscopic cholecys-tectomies was almost 2-fold higher (195.2/105 vs 111.8/105) in patients with T2DM. The annual rate of laparoscopic pro-cedures showed an 11-year relative increase of 88.3% (from 117.0/105 to 220.3/105) in T2DM and 49.2% (from 79.2/105 to 118.2/105) in patients without T2DM (P<0.001), whereas the rate of open procedures showed an 11-year relative decrease of 27.6% in patients with T2DM and 37.9% in those without T2DM (P<0.001). The rate of emergency laparoscopic cho-lecystectomy was increased in the 11 years, whereas the rate of emergency open cholecystectomies was decreased (both P<0.001). Multivariate analysis revealed that older age, higher comorbidity and emergency cholecystectomy were associated with a higher IHM. Compared with patients without T2DM, patients with T2DM demonstrated a lower IHM after open cholecystectomy OR=0.82 (0.78-0.87), but a higher IHM after laparoscopic cholecystectomy (OR=1.18 (1.03-1.35))Time-trend analyses showed a signiifcant reduction in IHM in patients with or without T2DM after the two procedures. CONCLUSION: The rate of cholecystectomy was higher in patients with T2DM, and laparoscopic cholecystectomy was popularized in the past 11 years both in selective and emer-gency cholecystectomies.
To describe trends in the rates of discharge due to thoracic aortic aneurysm and dissection (TAAD) among patients with and without type 2 diabetes in Spain (2001-2012).We used national hospital ...discharge data to select all of the patients who were discharged from the hospital after TAAD. We focused our analysis on patients with TAAD in the primary diagnosis field. Discharges were grouped by diabetes status (diabetic or nondiabetic). Incidence was calculated overall and stratified by diabetes status. We divided the study period into 4 periods of 3 years each. We analyzed diagnostic and surgical procedures, length of stay, and in-hospital mortality.We identified 48,746 patients who were discharged with TAAD. The rates of discharge due to TAAD increased significantly in both diabetic patients (12.65 cases per 100,000 in 2001/2003 to 23.92 cases per 100,000 in 2010/2012) and nondiabetic patients (17.39 to 21.75, respectively). The incidence was higher among nondiabetic patients than diabetic patients in 3 of the 4 time periods.The percentage of patients who underwent thoracic endovascular aortic repair increased in both groups, whereas the percentage of patients who underwent open repair decreased. The frequency of hospitalization increased at a higher rate among diabetic patients (incidence rate ratio 1.14, 95% confidence interval CI 1.07-1.20) than among nondiabetic patients (incidence rate ratio 1.08, 95% CI 1.07-1.11). The in-hospital mortality was lower in diabetic patients than in nondiabetic patients (odds ratio 0.83, 95% CI 0.69-0.99).The incidence rates were higher in nondiabetic patients. Hospitalizations seemed to increase at a higher rate among diabetic patients. Diabetic patients had a significantly lower mortality, possibly because of earlier diagnoses, and improved and more readily available treatments.
To examine trends in incidence and outcomes of heart failure (HF) hospitalizations among patients with or without chronic obstructive pulmonary disease (COPD) in Spain (2001–2015).
We used national ...hospital discharge data to select hospital admissions for HF as primary diagnosis. Incidence, comorbidities, diagnostic and therapeutic procedures, length of hospital stay (LOHS), readmissions rate, costs and in hospital mortality (IHM) was analyzed according to the presence or absence of COPD. Charlson comorbidity index (CCI) was used to assess comorbidity.
We identified 1,501,811 admissions for HF (19.55% with COPD). Incidence was significantly higher in COPD patients for all years analyzed. We found a significant increase in crude incidence over time in both groups of patients. Overall the incidence was 2.42-times higher among COPD patients (IRR 2.42; 95%CI 2.39–2.46). The joinpoint analysis showed that among men with COPD admissions for HF increased by 2.90% per year. Time trend analyses showed a significant decrease in IHM for both groups. Factors independently associated with higher IHM in both groups included: female gender, higher age, comorbidities according to CCI, longer LOHS and readmissions. The presence of COPD was not associated with a higher IHM in patients hospitalized with HF (OR0.98, 95%CI 0.96–1.01).
Among men suffering COPD the incidence of HF hospitalizations increased from 2001 to 2015. Incidence of hospitalizations was more than twice higher in the COPD population. IHM decreased over time in both groups. Female gender and readmission predict higher IHM. There were no differences in mortality between patients with and without COPD.

We examined fifteen years trends (2001-2015) in the use of non-invasive ventilation (NIV), invasive mechanical ventilation (IMV) or both (NIV+IMV) among patients hospitalized for community acquired ...pneumonia (CAP). We also analyzed trends overtime and the influence of patient factors in the in-hospital mortality (IHM) after receiving NIV, IMV or NIV+IMV.
Observational retrospective epidemiological study. Our data source was the Spanish National Hospital Discharge Database.
Over a total of 1,486,240 hospitalized patients with CAP, we identified 56,158 who had received ventilator support in Spain over the study period. Of them, 54.82% received NIV, 37.04% IMV and 8.14% both procedures. The use of NIV and NIV+IMV increased significantly (p<0.001) over time (from 0.91 to 12.84 per 100.000 inhabitant and from 0.23 to 1.19 per 100.000 inhabitants, respectively), while the IMV utilization decreased (from 3.55 to 2.79 per 100,000 inhabitants; p<0.001). Patients receiving NIV were the oldest and had the highest mean value in the Charlson comorbidity index (CCI) score and readmission rate. Patients who received only IMV had the highest IHM. Factors associated with IHM for all groups analyzed included age, comorbidities and readmission. IHM decreased significantly over time in patients with CAP who received NIV, IMV and NIV+IMV.
We found an increase in NIV use and a decline in IMV utilization in patients hospitalized for CAP over the study period. Patients receiving NIV were the oldest and had the highest CCI score and readmission rate. IHM decreased significantly over time in patients with CAP who received NIV, IMV and NIV+IMV.
