目的探讨原发性中枢神经系统淋巴瘤(PCNSL)患者的预后因素及不同治疗方法的临床效果。方法回顾性分析1975年1月至2016年12月美国SEER数据库中4812例PCNSL患者的临床资料。其中男性2831例,女性1981例,男女比例为1.4∶1.0;发病年龄<60岁者2236例(46.47%),60~<75岁者1718例(35.70%),≥75岁者858例(17.83%);幕上肿瘤2417例(50.23%),幕下肿瘤299例(6.21%),脑内多发肿瘤554例(11.51%),其他或未指明部位的脑部肿瘤1542例(32.04%);弥漫大B细胞淋巴瘤(DLBCL)3513例(73.00%),非DLBCL 234例(4.86%),其他或未指明类型的淋巴瘤1065例(22.13%);治疗方式为单独活检的2010例(41.77%),单独部分切除61例(1.27%),单独完全切除54例(1.12%),活检+化疗2384例(49.54%),部分切除+化疗159例(3.30%),完全切除+化疗144例(2.99%)。采用单因素及多因素Cox回归模型分析影响患者总体生存的预后因素;采用Fine-Gray检验与竞争风险模型研究影响患者肿瘤特异性生存的预后因素;生存分析采用Kaplan-Meier法,并通过Log-rank进行比较。结果单因素及多因素Cox风险回归模型分析结果显示,影响PCNSL患者总体生存的独立预后因素包括年龄、种族、婚姻状态、肿瘤部位、病理学亚型、手术、化疗、合并其他恶性肿瘤、合并HIV感染等。Fine-Gray检验与竞争风险模型分析结果显示,影响患者肿瘤特异生存的独立预后因素包括年龄、种族、婚姻状态、肿瘤部位、病理学亚型、手术方式、化疗、合并其他恶性肿瘤、合并HIV感染,而性别与放疗均与肿瘤特异生存无明显相关性。与活检相比,PCNSL患者可能从手术切除中获益(部分切除:HR=0.805,95%CI:0.656~0.989,P=0.04;完全切除:HR=0.521,95%CI:0.414~0.656,P<0.01)。Kaplan-Meier生存分析结果显示,活检+化疗组中位生存时间为28个月(95%CI:24.497~31.503),单独活检组为2个月(95%CI:1.756~2.244),单独部分切除组为2个月(95%CI:1.410~2.590),单独完全切除组为19个月(95%CI:0~39.311),部分切除+化疗组为67个月(95%CI:46.187~87.813),完全切除+化疗组为84个月(95%CI:57.448~110.552),使用不同治疗方法的患者的中位生存时间的差异有统计学意义(P<0.01)。结论手术切除可能改善部分PCNSL患者的预后。化疗可能使肿瘤完全切除或部分切除患者的肿瘤特异生存时间延长。     

Association between atherosclerotic cardiovascular diseases risk and renal outcome in patients with type 2 diabetes mellitus

AimsChronic kidney disease (CKD) and diabetes mellitus increase atherosclerotic cardiovascular diseases (ASCVD) risk. However, the association between renal outcome of diabetic kidney disease (DKD) and ASCVD risk is unclear.MethodsThis retrospective study enrolled 218 type 2 diabetic patients with biopsy-proven DKD, and without known cardiovascular diseases. Baseline characteristics were obtained and the 10-year ASCVD risk score was calculated using the Pooled Cohort Equation (PCE). Renal outcome was defined as progression to end-stage renal disease (ESRD). The association between ASCVD risk and renal function and outcome was analyzed with logistic regression and Cox analysis.ResultsAmong all patients, the median 10-year ASCVD risk score was 14.1%. The median of ASCVD risk score in CKD stage 1, 2, 3, and 4 was 10.9%, 12.3%, 16.5%, and 14.8%, respectively (p = 0.268). Compared with patients with lower ASCVD risk (＜14.1%), those with higher ASCVD risk had lower eGFR, higher systolic blood pressure, and more severe renal interstitial inflammation. High ASCVD risk (>14.1%) was an independent indicator of renal dysfunction in multivariable-adjusted logistic analysis (OR, 3.997; 95%CI, 1.385–11.530; p = 0.010), though failed to be an independent risk factor for ESRD in patients with DKD in univariate and multivariate Cox analysis.ConclusionsDKD patients even in CKD stage 1 had comparable ASCVD risk score to patients in CKD stage 2, 3, and 4. Higher ASCVD risk indicated severe renal insufficiency, while no prognostic value of ASVCD risk for renal outcome was observed, which implied macroangiopathy and microangiopathy in patients with DKD were related, but relatively independent.     

Self-reported snoring is associated with chronic kidney disease in obese but not in normal-weight Chinese adults

BackgroundThe relationship between sleeping disorders and chronic kidney disease (CKD) has already been reported. Snoring, a common clinical manifestation of obstructive sleep apnea–hypopnea syndrome, is of clinical value in assessing sleeping disorder severity. However, investigations of the connection between snoring and CKD are limited, especially in normal-weight populations. This study assessed the relationship between snoring frequency and CKD in obese and normal-weight people in China.MethodsA community-based retrospective cross-sectional study of 3250 participants was performed. Study participants were divided into three groups – the regularly snoring group, occasionally snoring group, and never snoring group – based on their self-reported snoring frequency. CKD was defined as an estimated glomerular filtration rate of less than 60 mL/min/1.73 m². Multiple logistic regression analysis was used to explore the relevance between snoring frequency and CKD prevalence.ResultsThe CKD prevalence in obese participants was higher than that in normal-weight participants. Frequent snorers had a higher prevalence of CKD than those who were not frequent snorers in the obese group. Snoring frequency was correlated with CKD prevalence in obese participants independent of age, sex, smoking and drinking status, systolic blood pressure, triglyceride level, high-density lipoprotein, and homeostasis model assessment of insulin resistance (odds ratio: 2.66; 95% CI: 1.36–5.19; p=.004), while the same relationships did not exist in normal-weight participants (odds ratio: 0.79; 95% CI: 0.32–1.98; p=.614).ConclusionsSnoring appears to be independently associated with CKD in obese but not in normal-weight Chinese adults.     

Tacrolimus versus cyclophosphamide for patients with idiopathic membranous nephropathy and treated with steroids: a systematic review and meta-analysis of randomized controlled trials

BackgroundThe therapeutic effects of tacrolimus (TAC) versus cyclophosphamide (CTX) were not fully illustrated for patients with idiopathic membranous nephropathy (IMN).MethodsThe PubMed, EmBase, Cochrane library, and CNKI were systematically searched throughout March 2020 for randomized controlled trials evaluating the therapeutic effects of TAC versus CTX for IMN patients treated with steroids. The pooled relative risks (RRs) and weighted mean differences (WMDs) with 95% confidence intervals (CIs) were calculated using the random-effects model.ResultsTwelve trials recruited a total of 868 IMN patients were identified and contained in final meta-analysis. Patients in TAC group was associated with an increased incidence of overall remission (12 trials: 868 patients; RR: 1.21; 95% CI: 1.11–1.31; p < 0.001) and complete remission (12 trials: 868 patients; RR: 1.50; 95% CI: 1.25–1.80; p < 0.001). Moreover, we noted TAC therapy significantly reduced urinary protein excretion (9 trials: 567 patients; WMD: −1.06; 95%CI: −1.41 to −0.71; p < 0.001), and increased serum albumin (9 trials: 567 patients; WMD: 5.37; 95%CI: 2.97 to 7.77; p < 0.001) than CTX therapy. Furthermore, no significant difference between TAC and CTX for serum creatinine was detected (6 trials: 378 patients; WMD: 0.15; 95%CI: −3.46 to 3.75; p = 0.936). Finally, the risk of alopecia (p = 0.008), infection (p = 0.045), leukocytosis (p = 0.002), and elevated ALT/AST (p = 0.011) in TAC group was significantly lower than CTX group, whereas TAC was associated with an increased risk of tremor than CTX (p = 0.010).ConclusionsThis study found IMN patients treated with TAC combined with steroids provides a better therapeutic effect and less adverse events than those treated with CTX combined with steroids, with moderate-certainty evidence.     

Hand grip strength as a predictor of recovery from low back pain in the pregnant women-a prospective study

BackgroundLow back pain (LBP) is a common musculoskeletal problem during pregnancy with an estimated prevalence ranging from 30% to 78%. The symptoms usually disappear gradually after delivery, but some women may have persistent problems even later in their lives. The definite mechanism behind LBP during pregnancy remains unknown. Therefore, the purpose of this study was to investigate whether hand grip strength (HGS), which is a straightforward and reliable indicator of overall muscle strength, is associated with unrecovered LBP after delivery.Methods257 pregnant women who registered at obstetrics units in two tertiary hospitals from January 2016 to June 2017 and meanwhile suffered the LBP during pregnancy were included. They were grouped based on whether they recovered from LBP after delivery (recovery was de?ned as a pain rating of ≤3). The variables such as age, HGS, and education level were recorded and examined for the risk analysis of unrecovered LBP. Also, the Pearson correlation between HGS levels and pain intensities was investigated.ResultsLBP without recovery at two years after delivery was reported among 22.7% of the subjects. Women with increasing age, low HGS (<25 kg), LBP in a previous pregnancy, back pain, sick leave, and a large amount of physical demand (all p < 0.05), were more likely to report LBP without recovery. Besides, there was a significant correlation between HGS values and the intensities of LBP (r = ?0.525; p = 0.003).ConclusionsLow HGS has the highest OR value (adjusted OR = 9.12, P < 0.001) among these factors. The present findings may be used to design and encourage a specific stabilization exercise regime to build well stability of the lumbar spinal column and thus alleviating the LBP.
