Ultrastructural telepathology--remote EM-diagnostic via Internet

New collaboratory opportunities in ultrastructural research and diagnostics are now available on the Internet through the combination of digital image acquisition, remote operation of modern digitally controlled and automated electron microscopes, and the development of software specifically tailored for collaboratory needs. Remote experts can examine samples directly, and unique instruments can be utilized from anywhere. In the case of diagnostic dilemmas, the second-opinion expert is no longer constrained by problems inherent in the interpretation of preselected images. The remote examiner can independently choose the area of interest on the sample as well as select the appropriate magnification for an accurate diagnosis. With these capabilities and together with teleconferencing tools and securely accessible databases on-line, telepathology can provide increased effectiveness and support for diagnostics, research, and teaching in many areas. The authors report their experience with remote electron microscope diagnoses of pathological samples using two different dynamic imaging systems and discuss the main technical issues encountered. It appears that only minor technical issues need to be resolved before ultrastructural telepathology can be promoted for routine use in areas with high-speed Internet access.     

青少年病理性互联网使用者网络信息的认知加工特点

目的:考察青少年病理性互联网使用者对网络相关图片的认知加工特点。方法:以接受住院治疗的网络成瘾者为被试,采用点探测任务范式进行研究。结果:网络成瘾组对网络图片的注意偏向显著高于控制组,有明显的注意维持偏向;在图片的呈现时间为500ms的条件下,网络成瘾组对网络图片的注意偏向得分显著高于控制组,随后注意偏向下降,表现出接近-回避的注意模式。结论:网络成瘾组的注意偏向得分显著高于控制组,随后注意偏向下降,表现出接近-回避的注意模式。     

Information from Searching Content with an Ontology-Utilizing Toolkit (iSCOUT)

Radiology reports are permanent legal documents that serve as official interpretation of imaging tests. Manual analysis of textual information contained in these reports requires significant time and effort. This study describes the development and initial evaluation of a toolkit that enables automated identification of relevant information from within these largely unstructured text reports. We developed and made publicly available a natural language processing toolkit, Information from Searching Content with an Ontology-Utilizing Toolkit (iSCOUT). Core functions are included in the following modules: the Data Loader, Header Extractor, Terminology Interface, Reviewer, and Analyzer. The toolkit enables search for specific terms and retrieval of (radiology) reports containing exact term matches as well as similar or synonymous term matches within the text of the report. The Terminology Interface is the main component of the toolkit. It allows query expansion based on synonyms from a controlled terminology (e.g., RadLex or National Cancer Institute Thesaurus [NCIT]). We evaluated iSCOUT document retrieval of radiology reports that contained liver cysts, and compared precision and recall with and without using NCIT synonyms for query expansion. iSCOUT retrieved radiology reports with documented liver cysts with a precision of 0.92 and recall of 0.96, utilizing NCIT. This recall (i.e., utilizing the Terminology Interface) is significantly better than using each of two search terms alone (0.72, p=0.03 for liver cyst and 0.52, p=0.0002 for hepatic cyst). iSCOUT reliably assembled relevant radiology reports for a cohort of patients with liver cysts with significant improvement in document retrieval when utilizing controlled lexicons.     

Patient interest in recording family histories of cancer via the Internet

PurposeThis study investigated the interest of mammogram patients in using electronic tools for recording their family histories of cancer (FHC).MethodsSemistructured interviews were conducted with 65 patients visiting a breast center at a referral hospital in Cleveland, Ohio.ResultsMost (n = 40; 62%) respondents expressed interest in using an electronic tool for recording FHC and associated its use with a range of benefits to themselves, their families, and their health care providers. Women who were not interested (n = 25; 38%) in using an electronic tool for recording FHC were concerned about privacy issues, computer proficiency, and giving up the opportunity to provide family history information directly to the health care provider. Interest in using an electronic tool for recording FHC was not significantly associated with age, race, level of education or income, personal or FHC, or Internet access and frequency of use.ConclusionElectronic documentation of FHC was seen as largely desirable. However, clinical services to facilitate systematic family history documentation are likely to require more than one avenue for collecting and communicating this information, as not everyone who wants to provide a FHC to a health care provider is comfortable using the Internet to do so.     

Parents Seeking Health-Related Information on the Internet: Cross-Sectional Study

Background

The Internet represents an increasingly common source of health-related information, and it has facilitated a wide range of interactions between people and the health care delivery system.

Objective

To establish the extent of Internet access and use to gather information about health topics and the potential implications to health care among the adult population in Calabria region, Italy.

Methods

This cross-sectional study was conducted from April to June 2012. The sample consisted of 1544 adults aged ≥18 years selected among parents of public school students in the geographic area of Catanzaro in southern Italy. A 2-stage sample design was planned. A letter summarizing the purpose of the study, an informed consent form, and a questionnaire were given to selected student to deliver to their parents. The final survey was formulated in 5 sections: (1) sociodemographic characteristics, (2) information about chronic diseases and main sources of health care information, (3) information about Internet use, (4) data about the effects of using the Internet to search for health information, and (5) knowledge and use of social networks.

Results

A total of 1039 parents completed the questionnaire, with a response rate equivalent to 67.29%. Regarding health-related information types, 84.7% of respondents used the Internet to search for their own medical conditions or those of family members or relatives, 40.7% of parents reported looking for diet, body weight, or physical activity information, 29.6% searched for vaccines, 28.5% for screening programs, and 16.5% for smoking cessation tools and products. The results of the multiple logistic regression analysis showed that parents who looked for health-related information on the Internet were more likely to be female (OR 1.53, 95% CI 1.05-2.25), with a high school diploma (OR 1.69, 95% CI 1.02-2.81) or college degree (OR 2.14, 95% CI 1.21-3.78), younger aged (OR 0.96, 95% CI 0.94-0.99), with chronic conditions (OR 1.94, 95% CI 1.17-3.19), not satisfied with their general practitioner’s health-related information (OR 0.6, 95% CI 0.38-0.97), but satisfied with information from scientific journals (OR 1.99, 95% CI 1.33-2.98).

Conclusions

Our analyses provide important insights into Internet use and health information–seeking behaviors of the Italian population and contribute to the evidence base for health communication planning. Health and public health professionals should educate the public about acquiring health information online and how to critically appraise it, and provide tools to navigate to the highest-quality information. The challenge to public health practice is to facilitate the health-promoting use of the Web among consumers in conjunction with their health care providers.
