ObjectiveTo determine the impact of socioeconomic status using median household income within the patient's community on rate of readmission among patients with heart failure (HF).Patients and MethodsWe derived a study cohort of patients who were admitted from January 1, 2013, through December 31, 2014, with congestive HF from the Healthcare Cost and Utilization Project National Readmission Database. Patients were stratified into quartiles according to the estimated median household income of residents in the patient's ZIP Code (quartile 1, lowest; quartile 4, highest). The primary outcome was 30-day readmission. We used univariate and multivariate models to compare patients with respect to baseline characteristics, income quartiles, and 30-day readmission.ResultsAbout 20% (110,152 of 546,841) of patients with an index HF admission were readmitted within the first 30 days. Patients in the lowest income quartile had a higher readmission rate compared with those in the highest income quartile (21.1% [35,422 of 167,625] vs 19.5% [20,771 of 106,353]; P<.001). Patients within the lowest income group had higher odds of readmission for cardiovascular causes compared with the highest income group (50.6% [17,923 of 35,422] vs 48.8% [10,136 of 20,771; P<.001). Readmissions within the lowest income group accounted for 30% of all rehospitalization-related costs at $715 million. Multivariate analysis confirmed a higher rate of 30-day readmission among patients in the lowest income group compared with those in the highest group (adjusted odds ratio, 1.11; 95% CI, 1.08-1.13).ConclusionOur study shows that patients in communities with the lowest quartile of income have a higher rate of readmission following the index HF admission with high associated costs. Readmission reporting and reimbursement adjustments should account for these socioeconomic inequalities. 相似文献

Eosinophils play a homeostatic role in the body’s immune responses. These cells are involved in combating some parasitic, bacterial, and viral infections and certain cancers and have pathologic roles in diseases including asthma, chronic rhinosinusitis with nasal polyps, eosinophilic gastrointestinal disorders, and hypereosinophilic syndromes. Treatment of eosinophilic diseases has traditionally been through nonspecific eosinophil attenuation by use of glucocorticoids. However, several novel biologic therapies targeting eosinophil maturation factors, such as interleukin (IL)-5 and the IL-5 receptor or IL-4/IL-13, have recently been approved for clinical use. Despite the success of biologic therapies, some patients with eosinophilic inflammatory disease may not achieve adequate symptom control, underlining the need to further investigate the contribution of patient characteristics, such as comorbidities and other processes, in driving ongoing disease activity. New research has shown that eosinophils are also involved in several homeostatic processes, including metabolism, tissue remodeling and development, neuronal regulation, epithelial and microbiome regulation, and immunoregulation, indicating that these cells may play a crucial role in metabolic regulation and organ function in healthy humans. Consequently, further investigation is needed into the homeostatic roles of eosinophils and eosinophil-mediated processes across different tissues and their varied microenvironments. Such work may provide important insights into the role of eosinophils not only under disease conditions but also in health. This narrative review synthesizes relevant publications retrieved from PubMed informed by author expertise to provide new insights into the diverse roles of eosinophils in health and disease, with particular emphasis on the implications for current and future development of eosinophil-targeted therapies. 相似文献

ObjectiveTo examine the risk of any and specific potentially preventable hospitalizations (PPHs) for adults with cerebral palsy (CP) or spina bifida (SB). We hypothesize that PPH risk is greater among adults with CP/SB compared with the general population.Patients and MethodsUsing January 1, 2007, to December 31, 2017, national private administrative claims data (OptumInsight) in the United States, we identified adults with CP/SB (n=10,617). Adults without CP/SB were included as controls (n=1,443,716). To ensure a similar proportion in basic demographics, we propensity-matched our controls with cases in age and sex (n=10,617). Generalized estimating equation models were applied to examine the risk of CP/SB on PPHs. All models were adjusted for age, sex, race/ethnicity, health indicators, US Census Division data, and socioeconomic variables. Adjusted odds ratios were compared within a 4-year follow-up.ResultsAdults with CP/SB had higher risk for any PPH (odds ratio [OR], 4.10; 95% CI, 2.31 to 7.31), and PPHs due to chronic obstructive pulmonary disease/asthma (OR, 1.85; CI, 1.23 to 2.76), pneumonia (OR, 3.01; 95% CI, 2.06 to 4.39), and urinary tract infection (OR, 6.48; 95% CI, 3.91 to 10.75). Cases and controls who had an annual wellness visit had lower PPH risk (OR, 0.52; 95% CI, 0.41 to 0.67); similarly, adults with CP/SB who had an annual wellness visit compared with adults with CP/SB who did not had lower odds of PPH (OR, 0.75; 95% CI, 0.60 to 0.94).ConclusionAdults with pediatric-onset disabilities are at a greater risk for PPHs. Providing better access to preventive care and health-promoting services, especially for respiratory and urinary outcomes, may reduce PPH risk among this patient population. 相似文献

The objective of this study is to describe the clinical features and outcomes of patients with the newly defined vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic (VEXAS) syndrome. Nine men with somatic mutations in the UBA1 gene were identified; the most frequent variant was p.Met41Thr (7 of 9, 78%). The median age at VEXAS diagnosis was 74 (67, 76.5) years, and patients had a median duration of symptoms for 4 years before diagnosis. Refractory constitutional symptoms (88%), ear and nose chondritis (55%), and inflammatory arthritis (55%) were common clinical features. Vasculitis was noted in 44%. All patients had significantly elevated inflammatory markers and macrocytic anemia. Thrombocytopenia was present in 66% at diagnosis of VEXAS. Eight patients had bone marrow biopsies performed. All bone marrows were hypercellular, and there was vacuolization of the erythroid (100%) or myeloid precursors (75%). Glucocorticoids attenuated symptoms at prednisone doses ≥20 mg per day, but no other immunosuppressive agent showed consistent long-term control of disease. One patient with coexisting plasma-cell myeloma received plasma-cell–directed therapy with improvement of the inflammatory response, which is a novel finding. In conclusion, VEXAS syndrome is a clinically heterogeneous, treatment-refractory inflammatory condition caused by somatic mutation of the UBA1 gene. Patients often present with overlapping rheumatologic manifestations and persistent hematologic abnormalities. As such, internists and subspecialists, including pathologists, should be aware of this condition to avert diagnostic delay, now that the etiology of this syndrome is known. 相似文献

ObjectiveTo examine the sex differences in management and outcomes among patients with high-risk acute pulmonary embolism (PE).Patients and MethodsThe Nationwide Readmissions Database was used to identify hospitalizations with high-risk PE from January 1, 2016, to December 31, 2018. Differences in use of advanced therapies, in-hospital mortality, and bleeding events were compared between men and women.ResultsA total of 125,901 weighted hospitalizations with high-risk PE were identified during the study period; 46.3% were women (n=58,253). Women were older and had a higher prevalence of several comorbidities and risk factors of PE such as morbid obesity, diabetes mellitus, chronic pulmonary disease, heart failure, and metastatic cancer. Systemic thrombolysis and catheter-directed interventions were more commonly used among women; however, mechanical circulatory support was less frequently used. In-hospital mortality was higher among women in the unadjusted analysis (30.7% vs 27.8%, P<.001) and after propensity score matching (odds ratio [OR], 1.16; 95% confidence interval [CI], 1.08 to 1.25; P<.001), whereas the rates of intracranial hemorrhage and non–intracranial hemorrhage were not different. On multivariate regression analysis, female sex (OR, 1.18; 95% CI, 1.15 to 1.21; P<.001) was independently associated with increased odds of in-hospital mortality.ConclusionIn this contemporary observational cohort of patients admitted with high-risk PE, women had higher rates of in-hospital mortality despite receiving advanced therapies more frequently, whereas the rate of major bleeding events was not different from men. Efforts are needed to minimize the excess mortality observed among women. 相似文献

ObjectiveTo determine the impact of antibiotic therapy (ATBT) on outcomes of renal cyst infection (CyI) in patients with polycystic kidney disease.Patients and MethodsWe undertook a single-center retrospective study of CyI in autosomal dominant polycystic kidney disease (January 1, 2000, through December 31, 2018). Cyst infections were classified as definite (microbiologically proven), probable (radiologic signs), or possible (clinical or biologic signs only). We studied the determinants of ATBT failure (persistence of infection beyond 72 hours of microbiologically adequate initial ATBT, with requirement for ATBT change, cyst drainage, or nephrectomy) and recurrences (>14 days after the end of ATBT).ResultsAmong 90 patients, 139 CyIs (11 definite, 74 probable, 54 possible) were compiled. Cultures were positive in 106 of 139 (76%) episodes, with Escherichia coli found in 89 of 106 (84%). Treatment failures and recurrences within 1 year of follow-up were more frequent in definite/probable CyI (20/85 [34%] and 16/85 [19%]) than in possible CyI (2/54 [4%] and 4/54 [7%]; P<.01 and P=.08, respectively). Male sex (odds ratio [OR], 7.79; 95% CI, 1.72 to 46.68; P<.01), peak C-reactive protein level above 250 mg/L (OR, 7.29; 95% CI, 1.78 to 35.74; P<.01; to convert C-reactive protein values to nmol/L, multiply by 9.524), and cyst wall thickening (OR, 7.70; 95% CI, 1.77 to 43.47; P=.01) but not the modalities of initial ATBT were independently associated with higher risk of failure. In a Cox proportional hazards model, kidney transplant recipients exhibited higher risk of recurrence (hazard ratio, 3.76; 95% CI, 1.06 to 13.37; P=.04), whereas a total duration of ATBT of 28 days or longer was protective (hazard ratio, 0.02; 95% CI, 0.00 to 0.16; P<.001), with an inverse correlation between duration and recurrence (81% for treatment <21 days, 47% for 21 to 27 days, 2% for ≥28 days; P<.0001).ConclusionInitial first-line ATBT had no significant effect on renal CyI treatment failure. Treatment duration of 28 days and longer reduced recurrences. 相似文献

ObjectiveTo investigate the extent to which 2 measures of physical fitness—walking pace and handgrip strength—are associated with life expectancy across different levels of adiposity, as the relative importance of physical fitness and adiposity on health outcomes is still debated.Patients and MethodsUsual walking pace (self-defined as slow, steady/average, brisk), dynamometer-assessed handgrip strength, body mass index (BMI), waist circumference, and body-fat percentage determined at baseline in the UK Biobank prospective cohort study (March 13, 2006, to January 31, 2016). Life expectancy was estimated at 45 years of age.ResultsThe median age and BMI of the 474,919 participants included in this analysis were 58.2 years and 26.7 kg/m2, respectively; over a median follow-up of 6.97 years, 12,823 deaths occurred. Participants reporting brisk walking pace had longer life expectancies across all levels of BMIs, ranging from 86.7 to 87.8 years in women and 85.2 to 86.8 years in men. Conversely, subjects reporting slow walking pace had shorter life expectancies, being the lowest observed in slow walkers with a BMI less than 20 kg/m2 (women: 72.4 years; men: 64.8 years). Smaller, less consistent differences in life expectancy were observed between participants with high and low handgrip strength, particularly in women. The same pattern of results was observed for waist circumference or body-fat percentage.ConclusionBrisk walkers were found to have longer life expectancies, which was constant across different levels and indices of adiposity. These findings could help clarify the relative importance of physical fitness and adiposity on mortality. 相似文献

ObjectiveTo examine the effect of high-intensity interval training (HIIT) on body fat mass and distribution in patients with myocardial infarction (MI) who underwent cardiac rehabilitation (CR).Patients and MethodsWe retrospectively screened 391 consecutive patients with MI enrolled in CR between September 1, 2015, and February 28, 2018. We included 120 patients who completed 36 CR sessions and underwent pretest-posttest dual-energy x-ray absorptiometry; 90 engaged in HIIT, and 30 engaged in moderate-intensity continuous training (MICT). High-intensity interval training included 4 to 8 alternating intervals of high- (30-60 seconds at a rating of perceived exertion [RPE] of 15-17 [Borg scale range, 6-20]) and low-intensity (1-5 minutes at RPE <14), and MICT performed for 20 to 45 minutes of exercise at an RPE of 12 to 14. Body weight, fat mass, and lean mass were measured via dual-energy x-ray absorptiometry with lipid profile measured via clinical procedures.ResultsThe HIIT and MICT groups were similar in age (67 vs 67 years), sex (26.7% [24 of 90 patients in the HIIT group] vs 26.7% [8 of 30 in the MICT group), and body mass index (30.3 vs 29.5 kg/m2) at baseline. The HIIT group had greater reductions in body fat percentage (P<.001), fat mass (P<.001), abdominal fat percentage (P<.001), waist circumference (P=.01), total cholesterol (P=.002), low-density lipoprotein cholesterol (P<.001), and triglycerides (P=.006). Improvements in total body mass and body mass index were not different across groups. After matching exercise duration, exercise intensity, and energy expenditure, HIIT-induced improvements in total fat mass (P=.02), body fat percentage (P=.01), and abdominal fat percentage (P=.02) persisted.ConclusionOur data suggest that supervised HIIT results in significant reductions in total fat mass (P<.001) and abdominal fat percentage (P<.001) and improved lipid profile in patients with MI who undergo CR. 相似文献

Constipation is a common symptom that may be primary (idiopathic or functional) or associated with a number of disorders or medications. Although most constipation is self-managed by patients, 22% seek health care, mostly to primary care physicians (>50%) and gastroenterologists (14%), resulting in large expenditures for diagnostic testing and treatments. There is strong evidence that stimulant and osmotic laxatives, intestinal secretagogues, and peripherally restricted μ-opiate antagonists are effective and safe; the lattermost drugs are a major advance for managing opioid-induced constipation. Constipation that is refractory to available laxatives should be evaluated for defecatory disorders and slow-transit constipation using studies of anorectal function and colonic transit. Defecatory disorders are often responsive to biofeedback therapies, whereas slow-transit constipation may require surgical intervention in selected patients. Both efficacy and cost should guide the choice of treatment for functional constipation and opiate-induced constipation. Currently, no studies have compared inexpensive laxatives with newer drugs that work by other mechanisms. 相似文献

Physical inactivity and psychosocial stress are prevalent in residents of the United States. The purpose of this article is to review the interaction between these 2 conditions and examine the effects of exercise on stress and cardiovascular (CV) health. A query of scientific references between 1974 to 2018 was performed using the PubMed search engine accessing the MEDLINE database using the search terms psychosocial stress, CV disease (CVD), physical activity, exercise, cardiac rehabilitation, and team sports. Psychosocial stress is a strong independent risk factor for adverse CV events. Conversely, people who experience CV events subsequently have drastically elevated rates of new-onset mental health disorders, including depression and anxiety. Psychosocial stress and CVD often trigger self-reinforcing feedback loops that can worsen mental health and cardiac prognosis. Exercise predictably improves CV health and prognosis and also is effective at lowering levels of psychosocial stress. Group exercise in particular seems to provide social support while at the same time boosting fitness levels and, thus, may be the single most important intervention for patients with concomitant CVD and emotional stress. Collaborative physical activity, such as group exercise, team sports, interactive physical play, and cardiac rehabilitation programs, have the potential to improve mental health and CV prognosis. 相似文献

ObjectiveTo assess the prevalence of coagulation abnormalities in patients with systemic light chain (AL) amyloidosis and their association with disease-related characteristics, disease progression, and survival.Patients and MethodsThis is a retrospective study of patients with AL amyloidosis seen at Mayo Clinic, Rochester, Minnesota, from January 1, 2006, to December 31, 2015. We studied the association between abnormal coagulation parameters and baseline characteristics and their association with survival outcomes.ResultsThe study included 411 patients. Abnormalities at diagnosis included prolonged clotting times and coagulation factor deficiencies; prolonged prothrombin time (PT) and factor X (FX) deficiency were found in 19% (73 of 390) and 43% (177 of 411) of patients, respectively. The FX deficiency was associated with higher Mayo stage, involvement of more than 1 organ, liver and cardiac involvement, and greater than 10% bone marrow plasma cells. On univariate analysis, the risk for disease progression or death was higher in patients with abnormal values for PT and factor V, factor VII (FVII), FX, and factor XII compared with those with normal values. Prolonged PT and FVII and FX deficiencies were independent predictors of death after adjusting for Mayo stage and more than 1 organ involvement. Only 106 patients had repeat testing after treatment; no clear relationship was found between treatment response and changes in coagulation parameters.ConclusionCoagulation abnormalities occur in a significant proportion of patients with AL amyloidosis and are associated with advanced disease and inferior outcomes. Larger studies are needed to establish whether a relationship exists between treatment response and improvement in individual parameters. 相似文献

ObjectiveTo evaluate the association of baseline and postinfusion patient characteristics with acute kidney injury (AKI) in the month after chimeric antigen receptor T-cell (CAR-T) therapy.MethodsWe retrospectively reviewed records of 83 patients with non-Hodgkin lymphoma undergoing CAR-T therapy (axicabtagene ciloleucel) between June 2016 and November 2020. Patients were followed up to 1 month after treatment. Post–CAR-T AKI was defined as a more than 1.5-fold increase in serum creatinine concentration from baseline (on the day of CAR-T infusion) at any time up to 1 month after CAR-T therapy.ResultsOf 83 patients, 14 (17%) developed AKI during follow-up. At 1 month after CAR-T infusion, 10 of 14 (71%) AKI events had resolved. Lower baseline estimated glomerular filtration rate, use of intravenous contrast material, tumor lysis prophylaxis, higher peak uric acid and creatine kinase levels during follow-up, and change in lactate dehydrogenase from baseline to peak level within 1 month after initiation of CAR-T therapy were significantly associated with AKI incidence during follow-up. Incidence of AKI was also higher in patients who received higher doses of corticosteroids and tocilizumab.ConclusionAcute kidney injury occurred in approximately 1 in 6 patients who received axicabtagene ciloleucel for non-Hodgkin lymphoma. Patients with high tumor burden receiving higher total doses of corticosteroids or tocilizumab should be closely monitored for development of AKI. Lower baseline kidney function at CAR-T initiation, exposure to contrast material, and progressive increase in levels of tumor lysis markers (uric acid, lactate dehydrogenase, creatine kinase) after CAR-T infusion may predict risk of AKI during the 1 month after infusion. 相似文献

ObjectiveTo describe the risks, outcomes, and trends in patients older than 80 years undergoing coronary artery bypass grafting (CABG).MethodsWe retrospectively studied 1283 consecutive patients who were older than 80 years and underwent primary isolated CABG from January 1, 1993, to October 31, 2019, in our clinic. Kaplan-Meier survival probability and quartile estimates were used to analyze patients’ survival. Logistic regression models were used for analyzing temporal trends in CABG cases and outcomes. A multivariable Cox proportional hazards regression model was developed to study risk factors for mortality.ResultsOperative mortality was overall 4% (n=51) but showed a significant decrease during the study period (P=.015). Median follow-up was 16.7 (interquartile range, 10.3-21.1) years, and Kaplan-Meier estimated survival rates at 1 year, 5 years, 10 years, and 15 years were 90.2%, 67.9%, 31.1%, and 8.2%, respectively. Median survival time was 7.6 years compared with 6.0 years for age- and sex-matched octogenarians in the general US population (P<.001). Multivariable Cox regression analysis identified older age (P<.001), recent atrial fibrillation or flutter (P<.001), diabetes mellitus (P<.001), smoking history (P=.006), cerebrovascular disease (P=.04), immunosuppressive status (P=.01), extreme levels of creatinine (P<.001), chronic lung disease (P=.02), peripheral vascular disease (P=.02), decreased ejection fraction (P=.03) and increased Society of Thoracic Surgeons predicted risk score (P=.01) as significant risk factors of mortality.ConclusionAlthough CABG in octogenarians carries a higher surgical risk, it may be associated with favorable outcomes and increase in long-term survival. Further studies are warranted to define subgroups benefiting more from surgical revascularization. 相似文献

ObjectiveTo determine the incidence of influenza and noninfluenza respiratory viruses (NIRVs) pre-/post-implementation of public health measures aimed to decrease coronavirus disease 2019 (COVID-19) transmission using population-based surveillance data. We hypothesized that such measures could reduce the burden of respiratory viruses (RVs) transmitting via the same routes.Patients and MethodsAn interrupted time-series analysis of RV surveillance data in Alberta, Canada, from May 2017 to July 2020 was conducted. The burden of influenza and NIRVs before and after intervention initiation at week 11 was compared. The analysis was adjusted for seasonality, overdispersion, and autocorrelation.ResultsDuring the study period, an average of 708 and 4056 weekly respiratory multiplex molecular panels were conducted pre-/post-intervention, respectively. We found significant reductions in test positivity rates in the postintervention period for influenza (-94.3%; 95% CI, -93.8 to 97.4%; P<.001) and all NIRVs (-76.5%; 95% CI, -77.3 to -75.8%; P<.001) in the crude model, and -86.2% (95% CI, -91.5 to -77.4%: P<.001) and -75% (95% CI, -79.7 to -69.3%; P<.001), respectively, in the adjusted models. Subanalyses for individual viruses showed significant decreases in respiratory syncytial virus, human metapneumovirus, enterovirus/rhinovirus, and parainfluenza. For non–severe acute respiratory coronavirus 2 human coronaviruses, the decline was not statistically significant after adjustment (-22.3%; 95% CI, -49.3 to +19%, P=.246).ConclusionThe implementation of COVID-19 public health measures likely resulted in reduced transmission of common RVs. Although drastic lockdowns are unlikely to be required given widespread COVID-19 vaccination, targeted implementation of such measures can lower RV disease burden. Studies to evaluate relative contributions of individual interventions are warranted. 相似文献
