神经症的性压抑与心理因素的相关性研究

研究神经症患者潜在人格与性压抑和情绪的相关性.方法:对124例神经症患者进行了婚姻质量问卷(性生活、婚姻质量部份)、抑郁自评量表(以下简称SDS)、焦虑自评量表(以下简称SAS)及自编的性生活调查问卷、主题统觉测验(以下简称TAT)测评.结果:1、神经症伴性障碍组TAT潜在人格与对照组相比,在支配、性、援助、躯体社会攻击、财产破坏欲求、自我攻击、情绪变化欲求和情绪言语攻击性、躯体社会攻击、引诱、缺乏、丧失、灾害、丧失支持、躯体伤害压力上均较对照组显著增高,而成就欲求下降(P<005-001);与神经症无性障碍组相比,神经症伴性障碍组的成就、支配、教养、性欲求得分显著增高,情绪言语攻击欲求得分下降(P<001～005);2、神经症伴性障碍组的性生活质量低,性频度、性后快感均低.3、SDS、SAS与TAT中的负性欲求呈明显的相关性,性行为调查与婚姻质量量表中的性行为呈正相关.结论:神经症的性压抑与其潜在人格有密切的相关性.     

How to Optimize Radiological Images Captured from Digital Cameras, Using the Adobe Photoshop 6.0 Program

Over the past decade, the technology that permits images to be digitized and the reduction in the cost of digital equipment allows quick digital transfer of any conventional radiological film. Images then can be transferred to a personal computer, and several software programs are available that can manipulate their digital appearance. In this article, the fundamentals of digital imaging are discussed, as well as the wide variety of optional adjustments that the Adobe Photoshop 6.0 (Adobe Systems, San Jose, CA) program can offer to present radiological images with satisfactory digital imaging quality.     

Methodology used for "software for automated linkage in Italy" (SALI)

Linkage of epidemiological registries can provide cost-effective information on the associations between different diseases or exposures in the population under study and on completeness of surveillance system databases. We describe the program SALI (software for automated linkage in Italy) aimed at matching individual records from medium-sized registries (in the order of 100,000 records), where the desired outcome is to miss as few links as possible and, because of low link-likelihood (< 1%), a manual revision of matched pairs is feasible. SALI, developed in CA-Clipper language, uses registry files in dBase format. It requires only name, surname, and date of birth as key fields, and it allows for spelling errors in Italian or other Latin languages through a specific algorithm. Furthermore, a double-blind procedure ensures data confidentiality. The main linkage procedure is based on four stages, two automatic ones, and two where the operator can decide through specific windows whether to accept stage-selected matches. SALI takes into account possible errors in key fields thus reducing false negatives. It was used to solve the problem of linkage between AIDS and cancer registries in Italy. It can be used with every IBM-compatible computer system, assuring uniquely high portability.     

基于PACS的MRI影像多媒体教学与报告系统的研究

目的：开发基于医院影像归档和通讯系统（picture archiving and communication system，PACS）环境的MRI（磁共振显像）影像多媒体教学与报告系统。方法：医院PACS系统符合DICOM3.0标准，采用1000M光纤主干网，100M交换到桌面；在临床医生浏览工作站安装多媒体教学系统，在诊断工作站安装教学系统与报告系统；科学内容按部位分类，以树枝模式管理。教学字资料来源于具有一定权威的教科书、专及期刊。图像资料来源于各部位经病理及临床证实的病例，直接从PACS系统提取，经标注说明后，以件形式存放于PACS图像服务器硬盘。结果：MRI辅助影响教学系统能够实时调阅最合适病种的MRI征象、临床特点、病理、鉴别诊断、典型图像及注释、正常断面解剖等，供教学、诊断和报告参考。结论：PACS环境下MRI辅助影像学系统，能满足临床医生和低年资影像诊断医生对MRI影像知识进一步继续医学教育的需求，能为影像诊断医生提供教学及科研工具，提高MR室工作质量和工作效率。

A Web-Based Interactive Patient-Provider Software Platform Does Not Increase Patient Satisfaction or Decrease Hospital Resource Utilization in Total Knee and Hip Arthroplasty Patients in a Single Large Hospital System

BackgroundWeb-based platforms used to enhance patient-provider communication are being explored to improve patient satisfaction and care delivery, and decrease cost. This study tested a web-based interactive patient-provider software platform (IPSP), JointCOACH, which enabled patient communication with their care team and preparatory/recovery guidance. The aims of this study are to compare (1) patient satisfaction and (2) healthcare resource utilization by patients who underwent total knee and hip replacements and added IPSP to standard of care (SOC).MethodsThis study is a prospective, randomized clinical trial at a single large academic healthcare system. Between May 2018 and March 2020, 399 patients undergoing elective total hip or knee arthroplasty were randomized to SOC arm (n = 204) or SOC + IPSP arm (n = 195). Patient demographics, surgical details, and comorbidities were collected. Patient satisfaction was assessed using Visual Analog Scale and the Picker Patient Experience-15. Healthcare utilization was measured using length of stay, emergency department and office visits, office calls, readmissions, and reoperations at 30 and 90 days after surgery.ResultsNo difference was found in length of stay between SOC and SOC + IPSP. No differences were found in 30-day or 90-day satisfaction or in healthcare resource utilization (P > .05) including number of office and emergency department visits, phone calls, and readmissions.ConclusionStatistical differences were not found in satisfaction and healthcare utilization with the addition of IPSP to SOC. IPSP can be used to reinforce patient education and communication between the patient and provider, and should be evaluated as an element of virtual care rather than supplementing traditional in-office follow-up.Clinicaltrials.govMore information on this study can be found at clinicaltrials.gov NCT03499028.
