Survival after dementia diagnosis in five racial/ethnic groups

Introduction

Information on anticipated survival time after dementia diagnosis among racially/ethnically diverse patients is needed to plan for care and evaluate disparities.

Racial and Ethnic Disparities in Idiopathic Pulmonary Fibrosis: A UNOS/OPTN Database Analysis

We previously reported poorer survival among non-Hispanic blacks and Hispanics with idiopathic pulmonary fibrosis (IPF) compared to non-Hispanic whites at our center. In the current study, we hypothesized that these disparities would exist in a nationwide cohort of wait-listed patients with IPF. We performed a retrospective cohort study of 2635 patients with IPF listed for lung transplantation between 1995 and 2003 at 94 transplant centers in the United States. The age-adjusted mortality rate was higher among non-Hispanic blacks [hazard ratio (HR) = 1.24, 95% confidence interval (CI) 1.06-1.45, p = 0.009] and Hispanics (HR = 1.29, 95% CI 1.06-1.56, p = 0.01) compared to non-Hispanic whites. These findings persisted after adjustment for transplantation, medical comorbidities and socioeconomic status. Worse lung function at the time of listing appeared to explain some of these differences (HR for non-Hispanic blacks after adjustment for forced vital capacity percent predicted = 1.16, 95% CI 0.98-1.36, p = 0.09; HR for Hispanics = 1.21, 95% CI 0.99-1.48, p = 0.056). In summary, black and Hispanic patients with IPF have worse survival than whites after listing for lung transplant.     

Obstructive sleep apnea remission following bariatric surgery: a national registry cohort study

BackgroundObstructive sleep apnea (OSA) is strongly associated with metabolic syndrome. Bariatric surgery is an effective available treatment for OSA; however, limited research predicts which patients undergoing bariatric surgery will undergo OSA resolution.ObjectivesTo determine perioperative predictors for OSA resolution following bariatric surgery using a national database.SettingUnited Kingdom national bariatric surgery database.MethodsThe UK National Bariatric Surgery Registry (NBSR) was interrogated to identify all patients with OSA that underwent primary bariatric surgery between January 2009 and June 2017. Those with at least 1 follow-up recording postoperative OSA status were selected for further analysis. Demographic, pre- and postoperative outcomes were collected and analyzed. Poisson multivariate regression was conducted to identify predictors of OSA remission.ResultsA total of 4015 bariatric cases were eligible for inclusion: 2482 (61.8%) patients underwent laparoscopic Roux-en-Y gastric bypass (LRYGB), 1196 (29.8%) sleeve gastrectomy (LSG), and 337 (8.4%) adjustable gastric banding (LAGB). Overall, the mean excess weight loss (EWL) % for the whole group was 61.2 (SD ± 27.2). OSA resolution was recorded in 2377 (59.2%) patients. Following Poisson regression, LRYGB (risk ratio [RR], 1.49 confidence interval [CI] 1.25–1.78) and LSG (RR, 1.46 [CI 1.22–1.75] were associated with approximately 50% increased likelihood of OSA remission compared with LAGB. Greater weight loss following intervention was associated with greater likelihood of OSA remission, while both greater age and greater preoperative body mass index (BMI) were associated with reduced likelihood of OSA remission (P < .001).ConclusionThis study demonstrated that metabolic surgery results in OSA remission in the majority of patients with obesity. Younger age, lower BMI preprocedure, greater %EWL and the use of LSG or LRYGB positively predicted OSA remission.     

Uveitis occurrence in early inflammatory back pain. Five years data from the prospective French nationwide DESIR cohort

ObjectiveUveitis is a frequent extra rheumatological manifestation in axial Spondyloarthritis (SpA). The aim of study was to evaluate the prevalence and incidence of uveitis over the first five years of a prospective nationwide cohort of patients with high suspicion of early axial SpA, and to evaluate its associated factors.MethodsDESIR is a prospective observational cohort of patients with recent onset inflammatory back pain (more than 3 months, less than 3 years), suggestive of axial SpA, All available factors in the database were compared between patients with and without uveitis at 5 years, by uni and then multivariate analysis. Baseline factors associated with new cases of uveitis occurrence over the 5 years were also analyzed. Significance: P less than 0.05.ResultsAfter 5 years, 91 patients (out of 480 with complete follow-up) had at least one uveitis episode, giving an estimated prevalence of 18.9% [95% CI: 15.4–22.4]. In multivariate analysis, uveitis was significantly associated with dactylitis, and elevated ESR. New incident uveitis occurred in 31 cases over 5 years, giving an estimated incidence rate of 1.29 [0.84–1.74]/100 patient-years. Incidence of new uveitis was associated in multivariate analysis with baseline factors: diagnosis of SpA, sacro iliac MRI inflammatory SPARCC score, dactylitis, syndesmophyte score. No significant association was found with HLA-B27, DMARDs, BASDAI, ASDAS, BASFI.ConclusionFive-years data of the DESIR cohort allowed an estimation of incidence rate of uveitis of 1.3/100p-y; over five years, uveitis was associated with dactylitis, biologic and sacro iliac MRI inflammation.     

Insulinemic and Inflammatory Dietary Patterns and Risk of Prostate Cancer

BackgroundHyperinsulinemia and inflammation are inter-related pathways that link diet with the risk of several chronic diseases. Evidence suggests that these pathways may also increase prostate cancer risk.ObjectiveTo determine whether hyperinsulinemic diet and inflammatory diet are associated with prostate cancer incidence and mortality.Design, setting, and participantsWe prospectively followed 41 209 men in the Health Professionals Follow-up Study (1986–2014). Scores for two validated dietary patterns were calculated from food frequency questionnaires at baseline and updated every 4 yr.Outcome measurements and statistical analysisTotal, advanced, and lethal prostate cancer outcomes were assessed. Multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were determined for associations between two empirical hypothesis-oriented dietary patterns—empirical dietary index for hyperinsulinemia and empirical dietary inflammatory pattern—and prostate cancer risk estimated using Cox proportional hazard regression.Results and limitationsDuring 28 yr of follow-up, 5929 incident cases of total prostate cancer, including 1019 advanced and 667 fatal, were documented. In multivariable-adjusted models, there was a 7% higher risk of advanced prostate cancer (HR: 1.07; 95% CI: 1.01–1.15) and a 9% higher risk of fatal prostate cancer (HR: 1.09; 95% CI: 1.00–1.18) per standard deviation (SD) increase in the hyperinsulinemic diet. When stratified by age, the hyperinsulinemic diet was associated with only earlier-onset aggressive prostate cancer (men under 65 yr), with per SD HRs of 1.20 (95% CI: 1.06–1.35) for advanced, 1.22 (1.04–1.42) for fatal, and 1.20 (1.04–1.38) for lethal. The inflammatory diet was not associated with prostate cancer risk in the overall study population, but was associated with earlier-onset lethal prostate cancer (per SD increase HR: 1.16; 95% CI: 1.00–1.35).ConclusionsHyperinsulinemia and inflammation may be potential mechanisms linking dietary patterns with the risk of aggressive prostate cancer, particularly earlier-onset disease.Patient summaryAvoiding inflammatory and hyperinsulinemic dietary patterns may be beneficial for the prevention of clinically relevant prostate cancer, especially among younger men.     

The comparative effects of metabolic surgery,SGLT2i,or GLP-1RA in patients with obesity and type 2 diabetes: a retrospective cohort study

BackgroundNew antidiabetic agents (sodium-glucose cotransporter-2 inhibitor [SGLT2i] and glucagon-like peptide-1 receptor agonist [GLP-1RA]) and metabolic surgery have protective effects on metabolic syndromes.ObjectivesTo compare the changes of metabolic parameters and costs among patients with obesity and type 2 diabetes undergoing metabolic surgery and initiating new antidiabetic agents over 12 months.SettingHong Kong Hospital Authority database from 2006–2017.MethodsThis is a population-wide retrospective cohort study consisting of 2616 patients (1810 SGLT2i, 528 GLP-1RA, 278 metabolic surgery). Inverse probability treatment weighting of propensity score was applied to balance baseline covariates of patients with obesity and type 2 diabetes who underwent metabolic surgery, or initiated SGLT2i or GLP-1RA. Metabolic parameters and direct medical costs were measured and compared from baseline to 12 months in metabolic surgery, SGLT2i, and GLP-1RA groups.ResultsPatients in all 3 groups had improved metabolic parameters over a 12-month period. Patients with metabolic surgery achieved significantly better outcomes in BMI (?5.39, ?.56, ?.40 kg/m², P < .001), % total weight loss (15.16%, 1.34%, 1.63%, P < .001), systolic (?2.21, ?.59, 1.28 mm Hg, P < .001) and diastolic (?1.16, .50, ?.13 mm Hg, P < .001) blood pressure, HbA1c (?1.80%, ?.77%, ?.80%, P < .001), triglycerides (?.64, ?.11, ?.09 mmol/L, P < .001), and estimated glomerular filtration rate (3.08, ?1.37, ?.41 mL/min/1.73m², P < .001) after 12 months compared with patients with SGLT2i and GLP1-RA. Although the metabolic surgery group incurred the greatest direct medical costs (US$33,551, US$10,945, US$10,627, P < .001), largely due to the surgery itself and related hospitalization, the total monthly direct medical expenditure of metabolic surgery group became lower than that of SGLT2i and GLP-1RA groups at 7 months.ConclusionBeneficial weight loss and metabolic outcomes at 12 months were observed in all 3 groups, among which the metabolic surgery group showed the most remarkable effects but incurred the greatest medical costs. However, studies with a longer follow-up period are warranted to show long-term outcomes.     

急诊和择期股疝临床特点及其修补后早期临床效果的回顾性队列研究

目的比较急诊和择期股疝的临床特点及修补术后早期临床效果。 方法回顾性分析2013年1月至2018年12月,赣州市人民医院手术治疗的股疝患者的临床资料,其中择期股疝组53例,急诊股疝组85例。 结果2组病例均以女性偏多,急诊组较择期组的病程偏长,年龄偏高;急诊组中有并存病的患者较多,以慢性阻塞性肺疾病、肝硬化多见。急诊组和择期组中肠梗阻患者分别为64例和4例,2组术中需肠切除、肠吻合的患者分别为14例和0例,但2组的修补方式差异无统计学意义。术后血清肿和浅表感染急诊组较择期组明显偏多,差异有统计学意义（P<0.05）。术后1个月内急诊组死亡7例,而择期组无死亡病例,K-M曲线分析Log-rank检验,差异有统计学意义（P<0.05）。 结论急诊股疝合并症较择期股疝多,病程长,术后并发症多,且术后1个月内死亡率高。所以股疝一旦确诊,应及时纠正患者的并存病,尽早手术,或许可以改善股疝患者的预后。     

脑梗死OCSP分型和预后

目的了解脑梗死患者OCSP临床分型的构成及不同亚型与预后及复发的关系。方法采用回顾性队列研究,登记2002年1月~2005年6月第四军医大学西京医院神经内科确诊的617例脑梗死患者,按照OCSP标准分型并进行随访,分析各亚型与预后及复发的关系。结果OCSP各亚型构成比分变为:TACI占7.3%,PACI23.3%,POCI6.0%,LACI63.4%,分型与预后明显相关,TACI的预后最差,POCI和LACI预后相对较好,PACI次之,卒中复发与分型无明显相关。结论OCSP分型作为一种脑梗死临床分型方法,可以为脑梗死的预后判断提供参考依据。
