LBP rs2232618 polymorphism contributes to risk of sepsis after trauma

Background

Previous study revealed that rs2232618 polymorphism (Phe436Leu) within LBP gene is a functional variant and associated with susceptibility of sepsis in traumatic patients. Our aim was to confirm the reported association by enlarging the population sample size and perform a meta-analysis to find additional evidence.

Methods

Traumatic patients from Southwest (n?=?1296) and Southeast (n?=?445) of China were enrolled in our study. After genotyping, the relationship between rs2232618 and the risk of sepsis was analyzed. Furthermore, we proceeded with a comprehensive literature search and meta-analysis to determine whether the rs2232618 polymorphism conferred susceptibility to sepsis.

Results

Significance correlation was observed between rs2232618 and risk of sepsis in Southwest patients (P?=?0.002 for the dominant model, P?=?0.006 for the recessive model). The association was confirmed in Southeast cohort (P?=?0.005 for the dominant model) and overall combined cohorts (P =?4.5?×?10^?4, P?=?0.041 for the dominant and recessive model). Multiple logistical regression analyses suggested that rs2232618 polymorphism was related to higher risk of sepsis (OR?=?1.77, 95% CI?=?1.26–2.48, P?=?0.001 in Southwest patients; OR?=?2.11, 95% CI?=?1.24–3.58, P?=?0.006 in Southeast cohort; OR?=?1.54, 95% CI?=?1.34–2.08, P?=?0.006 in overall cohort). Furthermore, meta-analysis of four studies (including the present study) confirmed that rs2232618 within LBP increased the risk of sepsis (OR?=?1.75, P?<?0.001 for the dominant model; OR?=?6.08, P?=?0.003 for the recessive model; OR?=?2.72, P?<?0.001 for the allelic model).

Conclusions

The results from our replication study and meta-analysis provided firm evidence that rs2232618T allele significantly increased the risk of sepsis.

Solving Time Dependent Fokker-Planck Equations via Temporal Normalizing Flow

In this work, we propose an adaptive learning approach based on temporal normalizing flows for solving time-dependent Fokker-Planck (TFP) equations. It is well known that solutions of such equations are probability density functions, and thus our approach relies on modelling the target solutions with the temporal normalizing flows. The temporal normalizing flow is then trained based on the TFP loss function, without requiring any labeled data. Being a machine learning scheme, the proposed approach is mesh-free and can be easily applied to high dimensional problems. We present a variety of test problems to show the effectiveness of the learning approach.     

Long‐Term Clinical Outcomes and Survivorship of Total Hip Arthroplasty for Pyogenic Arthritis: A Retrospective Cohort Study of 168 Hips

ObjectiveThe aim of the present study was to evaluate the 10‐year outcomes of cementless total hip arthroplasty (THA) in adult patients with the late sequelae of septic arthritis of the hip.MethodsWe followed 166 consecutive patients (168 hips) who underwent cementless THA between March 2001 and December 2011. There were 79 men and 87 women, with a mean age of 50.4 years (range 21–76 years) at the time of index THA, all of whom had hip osteoarthritis secondary to hip pyogenic infection. The average duration of follow up was 10.6 years (range 6.9–17.2 years). Preoperative and postoperative clinical ratings were evaluated, including the hip dysfunction and osteoarthritis outcome score (HOOS), the Harris hip score (HHS), range of motion, a 100‐point visual analog scale for hip pain, and the severity of limp and limb length discrepancy (LLD). The anteroposterior and lateral radiographs of the hip and full‐length view of the lower extremities were obtained to assess the position of the components, radiolucent lines, osteolysis, loosening of components, and heterotopic ossification. The intraoperative and postoperative complications were also recorded.ResultsThe mean HSS and hip pain score were 44.2 points (range 29–66 points) and 42.5 points (range 32–64 points), respectively, before the index surgery and significantly improved to 88.1 points (range 78–96 points) and 15.1 points (range 10–26 points), respectively, at final follow‐up examination. The HOOS and range of motion also improved significantly. The mean limb length discrepancy was reduced from 2.6 to 0.8 cm. The limp at last follow‐up examination was moderate in 3 cases because of hip osteoarthritis in the other limb, slight in 26, and absent in 137. A radiolucent line was observed in 12 hips (7.1%) around the acetabular or femoral components. A progressive radiolucent line around the undersized femoral stem in all zones was seen in 1 hip, resulting in aseptic loosening and breakage of the femoral component. There were 8 cases of intraoperative fracture, 7 cases of dislocation, and 7 cases of transient nerve palsy. Recurrence of infection occurred in 2 hips. Revision surgery was conducted in 2 hips because of isolated loosening of the acetabular cup and the femoral stem, respectively. Kaplan–Meier survival was 97% at 10 years, with revision for any reason with any component as an end‐point.ConclusionImproved surgical techniques and development of components with various sizes provided favorable results for cementless THA conducted for late sequelae of sepsis in these young and active patients. Although the incidence of complications was relatively high, the complications were treated successfully.     

Epirubicin-loaded beads transarterial prostatic arterial chemoembolization is a promising treatment for advanced prostate cancer with lower urinary tract obstruction or hematuria—a case series report

BackgroundProstatic arterial embolization (PAE) is an effective minimally invasive treatment for lower urinary tract obstruction and hematuria in patients with benign prostatic hyperplasia (BPH). This study was aim to evaluate the safety and short-term efficacy of drug epirubicin-loaded beads transarterial prostatic arterial chemoembolization (DEB-PACE) for the treatment of advanced prostate cancer (PC) with lower urinary tract obstruction or hematuria.MethodsA total of 8 patients with advanced PC undergoing DEB-PACE from August 2020 to February 2022 were retrospectively enrolled. The patients were followed up at 1 week, 1, 3, 6 and 12 months after DEB-PACE. The origin of prostatic arteries, technical success, clinical success rate, duration of the indwelling urinary catheter, International Prostate Symptom Score (IPSS), QoL score (quality of life), prostate volume (PV), prostate-specific antigen (PSA) level and complications were recorded. The short-term efficacy (changes in IPSS, PV and QoL value from baseline to 3 months) were analysed.ResultsThere were 17 prostatic arteries in 8 patients, which mainly originated from internal pudendal artery (11/17, 64.7%), the technical success rate is 100%. After treatment, the symptoms of lower urethral obstruction in 8 patients were significantly improved that PSA, PV, IPSS and QoL level were significantly reduced. The catheter was successfully removed within 1 week on average, and 2 patients with hematuria disappeared within 5 days. The clinical success rate is 100%. At 1 month postoperatively, mean PV reduction was 30.28±6.963 cm³ (P=0.0457), mean IPSS reduction was 21.13±2.887 points (P=0.0042), mean QoL reduction was 3.75±0.366 points (P=0.006). At 3 months postoperatively, mean PV reduction was 46.14±8.906 cm³ (P=0.0112), mean IPSS reduction was 24.5±2.398 points (P=0.0003), mean QoL reduction was 4.25±0.25 points (P=0.0003). There were no serious complications occurred in all patients.ConclusionsDEB-PACE is a promising treatment for advanced PC with lower urinary tract obstruction or hematuria. However, the efficacy and safety of DEB-PACE for advanced PC is needed to validated by prospective large sample randomized controlled study.     

阑尾黏液性肿瘤病理学特征及预后分析

目的探讨基于2010版WHO分类的各类阑尾黏液性肿瘤的病理学特征及预后。方法收集并复习2003年1月至2012年6月间在南京大学医学院附属鼓楼医院接受手术切除的70例阑尾黏液性肿瘤术后病理切片,按照2010年消化系统肿瘤WHO新分类,将阑尾黏液性肿瘤分为5种类型：阑尾黏液性腺瘤／囊腺瘤（MA）、低级别黏液性肿瘤（LAMN）、起源于阑尾的低级别腹膜假黏液瘤（PMP．L）、浸润性黏液腺癌（MAC）以及起源于阑尾的高级别腹膜假黏液瘤（PMP．H）。结果11例MA肿瘤上皮和黏液仅局限于黏膜肌层以内;术后无复发或死亡病例。41例LAMN黏液均可出现于黏膜肌层外阑尾壁或阑尾表面,其中39黏液湖内没有或仅见少数黏液上皮,上皮具有轻度异型性;有3例复发或进展,元死亡病例。7例PMP—L上皮具有轻度异型性,其中有4例黏液湖内上皮数量稀少或缺乏,其余3例上皮数量中等至较多：术后复发和死亡各1例。7例MAC和4例PMP—H均为浸润性肿瘤,至少局部出现高级别细胞学特征;术后复发4例,死亡3例（含2例复发后死亡）。MA和LAMN在组织学上表现为非浸润性肿瘤。而PMP-L、MAC和PMP-H则在生物学行为上表现为腺癌特征。结论阑尾黏液性肿瘤是一系列肿瘤谱系,其生物学行为取决于肿瘤性质和类型,统一、规范而准确的病理诊断对于治疗至关重要。
