腹腔镜前列腺癌根治术后自动结扎夹移位的原因分析及防治对策

目的分析腹腔镜前列腺癌根治术（LRP）术后自动结扎夹（Hem-o-lok）移位导致膀胱结石的原因，探讨预防LRP术后膀胱结石发生及其治疗的方法。 方法回顾性分析2014年1月至2019年12月中山大学附属第三医院收治的12例LRP术后发生Hem-o-lok移位致膀胱结石病例资料，包括手术方案、术中情况、Hem-o-lok放置部位及数量、吻合口张力、膀胱碎石术中所见等，分析Hem-o-lok移位致膀胱结石的可能因素。 结果12例患者病理分期T1a-T2cN0M0，均行经腹腔/腹膜外LRP，术中在吻合口附近使用Hem-o-lok 1～2枚，在前列腺侧韧带附近使用Hem-o-lok 4～8枚，术后6～15个月出现膀胱结石1～2颗，结石核心为Hem-o-lok，其中2例合并吻合口狭窄，1例合并吻合口Hem-o-lok嵌顿。采用经尿道狭窄环冷刀切开及瘢痕电切术处理膀胱颈狭窄，气压弹道碎石及取出Hem-o-lok，术后痊愈出院。 结论在LRP术中，合理使用Hem-o-lok以及熟练的吻合技术，是预防术后吻合口狭窄及减少其移位形成膀胱结石的关键。     

Residential mobility and chronic disease among World Trade Center Health Registry enrollees, 2004–2016

Residential mobility is hypothesized to impact health through changes to the built environment and disruptions in social networks, and may vary by neighborhood deprivation exposure. However, there are few longitudinal investigations of residential mobility in relation to health outcomes. This study examined enrollees from the World Trade Center Health Registry, a longitudinal cohort of first responders and community members in lower Manhattan on September 11, 2001. Enrollees who completed ≥2 health surveys between 2004 and 2016 and did not have diabetes (N = 44,089) or hypertension (N = 35,065) at baseline (i.e., 2004) were included. Using geocoded annual home addresses, residential mobility was examined using two indicators: moving frequency and displacement. Moving frequency was defined as the number of times someone was recorded as living in a different neighborhood; displacement as any moving to a more disadvantaged neighborhood. We fit adjusted Cox proportional hazards models with time-dependent exposures (moving frequency and displacement) and covariates to evaluate associations with incident diabetes and hypertension. From 2004 to 2016, the majority of enrollees never moved (54.5%); 6.5% moved ≥3 times. Those who moved ≥3 times had a similar hazard of diabetes (hazard ratio (HR) = 0.78; 95% Confidence Interval (CI): 0.40, 1.53) and hypertension (HR = 0.99; 95% CI: 0.68, 1.43) compared with those who never moved. Similarly, displacement was not associated with diabetes or hypertension. Residential mobility was not associated with diabetes or hypertension among a cohort of primarily urban-dwelling adults.     

The influence of luminance on displacement thresholds for continuous oscillatory movement

Displacement thresholds were determined for a sinusoidally-modulated contrast grating, having a spatial frequency of 2 c/deg, whose mean luminance could be varied. The grating underwent continuous oscillatory simple harmonic motion. Displacement thresholds were determined for frequencies of 1, 3, 5, 7 and 10 Hz using the method of limits for each mean grating luminance of 3.8, 8.9, 26, 62 and 134 cd/m2. With low oscillation frequencies a marked reduction in sensitivity is produced by reducing the mean luminance of the grating. This is not the case with higher oscillation frequencies when mean luminance has little effect upon sensitivity.

Measurement of fetal movements using multichannel ultrasound pulsed Doppler: Autorecognition of fetal movements by maximum entropy method

Changes in fetal movements indicate biophysical conditions and functional development. The precise evaluation of fetal movements in clinical medicine requires the development of a continuous automated monitoring technique. A basic study of the measurement of fetal movements was carried out by modifying the Doppler ultrasound module of a cardiotocograph to produce low-frequency Doppler signals and five simultaneous outputs at various depths. These outputs represent displacement inside tissue at the various depths. Signal processing was executed on a 32-bit computer with a high-accuracy displacement estimation technique using the arctangent method. Results showed successful tracking of minute movements, such as fetal breathing movements (FBM), while rejecting other movements derived from maternal breathing etc. Using spectral analysis by the maximum entropy method (MEM), fetal movements were classified in three groups (FBM, fetal gross movements (FGM) and fetal heart movements (FHM)), based on the character of their special peak frequencies. The order of movement recognition was first FGM, then FBM and lastly FHM. FBM were more successfully recognised by MEM than by conventional B-mode observation methods. Small body movements were difficult to recognise as FGM by MEM in some cases. Although further studies are required for clinical application, it appears that automated assessments of fetal movements should be possible with this technique.
