Prostatic Artery Embolization Using 100–300-μm Trisacryl Gelatin Microspheres to Treat Lower Urinary Tract Symptoms Attributable to Benign Prostatic Hyperplasia: A Single-Center Outcomes Analysis with Medium-Term Follow-up

PurposeTo report medium-term outcomes of prostatic artery embolization (PAE) using 100–300-μm trisacryl gelatin microspheres to treat lower urinary tract symptoms (LUTS) from benign prostatic hyperplasia (BPH) and to evaluate how cone-beam computed tomography-measured prostate gland volume (PGV), median lobe enlargement (MLE), age, and Charlson Comorbidity Index (CCI) affect these results.Materials and MethodsSeventy-four consecutive patients who underwent PAE from April 2014 through August 2018 were retrospectively reviewed. Patients had International Prostate Symptom Score (IPSS) >12, Quality of Life (QoL) score >2, prostate gland volume (PGV) >40 mL, age older than 45 years, and medical therapy failure. Twelve patients were excluded for bladder pathology or prostate cancer. Patients (n = 62, age = 71.8 ± 9.3 years, CCI = 3.5 ± 1.7, PGV = 174 ± 110 mL) had pre-procedure IPSS = 22.4 ± 5.6, QoL score = 4.4 ± 0.9, and post-void residual (PVR) = 172 ± 144 mL. Post-procedure values were compared to baseline at 1, 3, 6, 12, and 24 months. Associations between outcomes and PGV, MLE, age, and CCI were evaluated. Adverse event recording used Clavien-Dindo classification.ResultsOne month after PAE (n = 37), IPSS improved to 7.6 ± 5.2 (P < .0001) and QoL score improved to 1.7 ± 1.4 (P < .0001). At 3 months (n = 32), improvements continued, with IPSS = 6.4 ± 5.1 (P < .0001), QoL score = 1.2 ± 1.2 (P < .0001), PVR = 53 ± 41 mL (P < .001), and PGV = 73 ± 38 mL (P < .0001). Results were sustained at 6 months (n = 35): IPSS = 6.4 ± 4.1 (P < .0001), QoL score = 1.2 ± 1.2 (P < .0001), PVR = 68 ± 80 mL (P < .0001), PGV = 60 ± 19 mL (P < .001). At 12 months, patients (n = 26) had IPSS = 7.3 ± 5.5 (P < .0001), QoL score = 1.2 ± 0.8 (P <.0001), PVR = 89 ± 117 mL (P < .0001), PGV = 60 ± 48 mL (P < .01). At 24 months, patients (n = 8) had IPSS = 8.0 ± 5.4 (P < .0001), QoL score = 0.7 ± 0.5 (P < .0001), PVR = 91 ± 99mL (P = 0.17), and PGV = 30 ± 5mL (P = .11). Improvements were independent of PGV, MLE, age, and CCI. Two grade II urinary infections occurred.ConclusionsPAE with 100–300-μm microspheres produced sustained substantial improvements in LUTS, PGV, and PVR, which were independent of baseline PGV, MLE, age, or CCI.     

Cognitive and psychiatric symptoms in genetically determined Parkinson’s disease: a systematic review

The aim was to review the existing reports on cognitive and behavioural symptoms in monogenic forms of Parkinson’s disease (PD) and to identify recurring patterns of clinical manifestations in those with specific mutations. A systematic literature search was conducted to retrieve observational studies of monogenic PD. Data pertaining to cognitive and psychiatric manifestations were extracted using standardized templates. The PRISMA guidelines were followed. Of the 1889 citations retrieved, 95 studies on PD‐related gene mutations were included: 35 in SNCA, 35 in LRRK2, four in VPS35, 10 in Parkin, three in DJ1 and eight in PINK1. Nineteen studies (20%) provided adequate data from comprehensive cognitive assessment and 31 studies (32.6%) outlined psychiatric manifestations through the use of neuropsychiatric scales. Cognitive impairment was reported in all monogenic PD forms with variable rates (58.8% PINK1, 53.9% SNCA, 50% DJ1, 29.2% VPS35, 15.7% LRRK2 and 7.4% Parkin). In this regard, executive functions and attention were the domains most affected. With respect to psychiatric symptoms, depression was the most frequent symptom, occurring in 37.5% of PINK1 cases and 41.7% of VPS35 and LRRK2 cases. Co‐occurrence of cognitive decline with visual hallucinations was evidenced. Widespread accumulation of Lewy bodies, distinctive of SNCA, PINK1 and DJ1 mutations, results in higher rates of cognitive impairment. Similarly, a higher degree of visual hallucinations is observed in SNCA mutations, probably owing to the more widespread accumulation. The lower rates of α‐synuclein pathology in LRRK2 and Parkin may underpin the more benign disease course in these patients.     

妊娠早期症状与经前期症状之间的相关性分析

目的通过对妊娠早期症状与经前期症状之间的相关性分析,评估经前期症状对妊娠早期症状的预测价值。方法对2014年9~12月在郑州大学第一附属医院产科就诊的305例妊娠期妇女进行问卷调查,采用配对t检验对经前期症状和妊娠早期症状进行差异性分析,分别采用简单线性回归模型、多重线性回归模型对经前期症状与妊娠早期症状进行相关性分析。结果妊娠早期症状出现的频数及严重程度与经前期症状比较,差异均有统计学意义(t=6.9、t=6.7,P0.001);妊娠早期与经前期各症状平均严重程度之间存在大量的相关性;妊娠早期症状的总体严重程度与经前期症状的总体严重程度呈显著性相关(b=0.4,95%CI=0.3~0.5,P0.001)。结论妊娠早期与经前期具有相似的症状模式,妊娠早期出现的某一精神心理症状可通过经前期症状预测,经前期易怒症状的严重程度是预测妊娠早期症状总体严重程度的最佳指标。
