Behavioral Nutrition Interventions Using e- and m-Health Communication Technologies: A Narrative Review.

e- and m-Health communication technologies are now common approaches to improving population health. The efficacy of behavioral nutrition interventions using e-health technologies to decrease fat intake and increase fruit and vegetable intake was demonstrated in studies conducted from 2005 to 2009, with approximately 75% of trials showing positive effects. By 2010, an increasing number of behavioral nutrition interventions were focusing on body weight. The early emphasis on interventions that were highly computer tailored shifted to personalized electronic interventions that included weight and behavioral self-monitoring as key features. More diverse target audiences began to participate, and mobile components were added to interventions. Little progress has been made on using objective measures rather than self-reported measures of dietary behavior. A challenge for nutritionists is to link with the private sector in the design, use, and evaluation of the many electronic devices that are now available in the marketplace for nutrition monitoring and behavioral change.

Preconception care for diabetic women for improving maternal and infant health.

BACKGROUND: Infants born to mothers with pre-existing type 1 or type 2 diabetes mellitus are at greater risk of congenital anomalies, perinatal mortality and significant morbidity in the short and long term. Pregnant women with pre-existing diabetes are at greater risk of perinatal morbidity and diabetic complications. The relationship between glycaemic control and health outcomes for both mothers and infants indicates the potential for preconception care for these women to be of benefit. This is an update of the original review, which was first published in 2010. OBJECTIVES: To assess the effects of preconception care in women with diabetes on health outcomes for mothers and their infants. SEARCH METHODS: We searched Cochrane Pregnancy and Childbirth's Trials Register (31 January 2017) and reference lists of retrieved articles. SELECTION CRITERIA: Randomised controlled trials (RCTs) assessing the effects of preconception care for diabetic women. Cluster-RCTs and quasi-RCTs were eligible for inclusion but none were identified. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed study eligibility, extracted data and assessed the risk of bias of the included studies. We checked data for accuracy and assessed the quality of the evidence using the GRADE approach. MAIN RESULTS: We included three trials involving 254 adolescent girls with type 1 or type 2 diabetes, with an overall unclear to high risk of bias. The three trials were conducted at diabetes clinics in the USA, and assessed the READY-Girls (Reproductive-health Education and Awareness of Diabetes in Youth for Girls) programme versus standard care.Considering primary outcomes, one trial reported no pregnancies in the trial period (12 months) (very low-quality evidence, with downgrading based on study limitations (risk of bias) and imprecision); in the other two trials, pregnancy was an exclusion criterion, or was not clearly reported on. None of the trials reported on the other primary maternal outcomes, hypertensive disorders of pregnancy and caesarean section; or primary infant outcomes, large-for-gestational age, perinatal mortality, death or morbidity composite, or congenital malformations. Similarly, none of the trials reported on the secondary outcomes, for which we had planned to assess the quality of the evidence using the GRADE approach (maternal: induction of labour; perineal trauma; gestational weight gain; long-term cardiovascular health; infant: adiposity; type 1 or 2 diabetes; neurosensory disability).The majority of secondary maternal and infant outcomes, and outcomes relating to the use and costs of health services were not reported by the three included trials. Regarding behaviour changes associated with the intervention, in one trial, participants in the preconception care group had a slightly higher score for the actual initiation of discussion regarding preconception care with healthcare providers at follow-up (nine months), compared with those in the standard care group (mean difference 0.40, 95% confidence interval -0.02 to 0.82 (on a scale of 0 to 4 points); participants = 87) (a summation of four dichotomous items; possible range 0 to 4, with 0 being no discussion). AUTHORS' CONCLUSIONS: There are insufficient RCT data available to assess the effects of preconception care for diabetic women on health outcomes for mothers and their infants.More high-quality evidence is needed to determine the effects of different protocols of preconception care for diabetic women. Future trials should be powered to evaluate effects on short- and long-term maternal and infant outcomes, and outcomes relating to the use and costs of health services. We have identified three ongoing studies that we will consider in the next review update.

CDROM: Classification of Duplicate gene RetentiOn Mechanisms.

BACKGROUND: Gene duplication is a major source of new genes that is thought to play an important role in phenotypic innovation. Though several mechanisms have been hypothesized to drive the functional evolution and long-term retention of duplicate genes, there are currently no software tools for assessing their genome-wide contributions. Thus, the evolutionary mechanisms by which duplicate genes acquire novel functions remain unclear in a number of taxa. RESULTS: In a recent study, researchers developed a phylogenetic approach that uses gene expression data from two species to classify the mechanisms underlying the retention of duplicate genes (Proc Natl Acad Sci USA 110:1740917414, 2013). We have implemented their classification method, as well as a more generalized method, in the R package CDROM, enabling users to apply these methods to their data and gain insights into the origin of novel biological functions after gene duplication. The CDROM R package, source code, and user manual for the R package are available for download from CRAN at https://cran.rstudio.com/web/packages/CDROM/ . Additionally, the CDROM R source code, user manual for running CDROM from the source code, and sample dataset used in this manuscript can be accessed at www.personal.psu.edu/rua15/software.html . CONCLUSIONS: CDROM is the first software package that enables genome-wide classification of the mechanisms driving the long-term retention of duplicate genes. It is user-friendly and flexible, providing researchers with a tool for studying the functional evolution of duplicate genes in a variety of taxa.

Efficacy of e-technologies in improving breastfeeding outcomes among perinatal women: a meta-analysis.

A growing line of research has highlighted that e-technologies may play a promising role in improving breastfeeding outcomes. The objective of this review was to synthesise the best of available evidence by conducting a meta-analysis to evaluate whether e-technologies have had any effect in improving breastfeeding outcomes among perinatal women. The review was conducted using nine electronic databases to search for English-language research studies from 2007 to 2014. A 'risk of bias' table was used to assess methodological quality. Meta-analysis was performed with the RevMan software. The Q test and I(2) test was used to assess the heterogeneity. The test of overall effect was assessed using z-statistics at P < 0.05. Of 1842 studies identified through electronic searches and reference lists, 16 experimental studies were selected after applying the inclusion and exclusion criteria. Half of the selected studies had a low risk of bias, from which a total of 5505 women in six countries in these studies were included. Meta-analyses revealed that e-technologies significantly improved exclusive breastfeeding initiation (z = 6.90, P < 0.00001), exclusive breastfeeding at 4 weeks (z = 2.12, P = 0.03) and 6 months (z = 3.2, P = 0.001), breastfeeding attitude (z = 3.01, P = 0.003) and breastfeeding knowledge (z = 4.54, P = < 0.00001) in subgroup analyses. This review provides support for the development of web-based, texting messaging, compact disc read-only memory, electronic prompts and interactive computer agent interventions for promoting and supporting breastfeeding.

Effect of Digital Nutrition Education Intervention on the Nutritional Knowledge Levels of Information Technology Professionals.

The purpose of the study was to determine the changes in knowledge of information technology (IT) professionals after receiving a nutrition education intervention for a month. The sample comprised of 40 IT professionals (29 males and 11 females). The sample was drawn from four IT companies of Hyderabad city using random sampling techniques. The data on the general information of the subjects was collected. The data regarding the commonly accessed sources of nutrition and health information by the subjects was also obtained from the study. The intervention study group received nutrition education by distribution of the developed CD-ROMs to them followed by interactive sessions. To assess the impact of nutrition education intervention, the knowledge assessment questionnaire (KAQ) was developed and administered before and after the education programme. A significant improvement in the mean nutritional knowledge scores was observed among the total study subjects from 22.30 to 40.55 after the intervention (p < 0.05). The findings support the importance of providing professionals with nutrition knowledge to promote healthy dietary behaviors.Thus, the method of e-learning and development of CD-Rom is essential for teaching the educated groups on nutrition, physical activity and overall health education to improve their health, lifestyle and eating habits.

A decision aid regarding treatment options for patients with an asymptomatic abdominal aortic aneurysm: a randomised clinical trial.

OBJECTIVE: Abdominal aortic aneurysm patients tend to be informed inconsistently and incompletely about their disorder and the treatment options open to them. The objective of this trial was to evaluate whether these patients are better informed and experience less decisional conflict regarding their treatment options after viewing a decision aid. DESIGN: A six-centre, randomised clinical trial comparing a decision aid plus regular information versus regular information from the surgeon. METHODS: Included patients had recently been diagnosed with an asymptomatic abdominal aortic aneurysm at least 4 cm in diameter. The decision aid consisted of a one-time viewing of an interactive CD-ROM elaborating on elective surgery versus watchful waiting. Generally, the decision aid advised patients with aneurysms less than 5.5 cm to agree to watchful waiting, for larger aneurysms the decision aid provided insight into the balance of benefit and harm of surgical and conservative approaches, taking into account age, co-morbidity and size of the aneurysm. The primary outcome was patient decisional conflict measured at 1 month follow-up (Decisional Conflict Scale). Secondary outcomes were patient knowledge, anxiety and satisfaction. RESULTS: In 178 aneurysm patients, decisional conflict scores did not differ significantly between the decision aid and the regular information groups (22 vs. 24 on the 0-100 Decisional Conflict Scale; p = .33). Patients in the decision aid group had significantly better knowledge (10.0 vs. 9.4 out of 13 points; p = .04), whereas anxiety levels (4.4 and 5.0 on a 0-21 scale; p = .73) and satisfaction scores (74 and 73 on a 0-100 scale; p = .81) were similar in both groups. CONCLUSION: In addition to regular patient-surgeon communication, a decision aid helps to share treatment decisions with abdominal aortic aneurysm patients by increasing their knowledge about the disorder and available treatment options without raising anxiety levels; however, it does not reduce decisional conflict, nor does it improve satisfaction.

Evaluation of self-contained PACS viewers on CD-ROM.

Providing patients and clinicians with self-contained PACS viewer on CD format is a common and necessary tool to share vital imaging data. However, to be useful, this tool should be reliable, robust, and convenient. Numerous PACS viewer options are available, often without empirical data to guide in choosing one for routine use. To assist in making a standardized choice for our institution, we chose four common viewers, benchmarked on four different workstations reflecting the variety of environments used by non-radiologist clinicians who would receive a CD. Four CD-based DICOM viewers from eFilm, Philips, Pacsgear Gearview, and iSite were examed on two radiology PACS workstations, a standard desktop computer, and a laptop using a test case consisting of a multi-series CTA with 13 series and 3,035 total images. Multiple objective measures, subjective measures, and presence of key features were evaluated including program time to load, image time to load, cine/movie mode, ability to adequately window and level, pan and zoom functionality, basic measurement tools, and perceived lag when scrolling through a multi-image series. Substantial differences in speed of operation and behavior on multiple systems were documented, which could potentially add several minutes to the time required to open and view a patient's imaging data. The eFilm and iSite viewers operated consistently and reliably across all tested computer environments. The iSite viewer, having among the quickest load times in the group tested and consistently low subjective scroll lag during series viewing, and also beneficially allowing partial viewing while images load in the background, was found to generate the best overall user experience. Because of these significant differences, we have recommended that our institution standardize all patient imaging CD creation using the iSite viewer.

Qualitative evaluation of a colorectal cancer education CD-ROM for Community Health Aides/practitioners in Alaska.

Colorectal cancer (CRC) is an important contributor to the cancer burden among Alaska Native people. CRC is the leading incident cancer and the second leading cause of cancer mortality among Alaska Native people. Completing recommended CRC screening procedures has the potential to reduce both CRC incidence and mortality. "Taking Action Colorectal Health," a multidimensional audiovisual, interactive CD-ROM, incorporates adult education learning principles to provide Alaska's Community Health Aides/Practitioners with timely, medically accurate, and culturally relevant CRC place-based education. Providing this resource on CD-ROM empowers learning within communities and places where people live or choose to learn. The dynamic process of developing, implementing, and evaluating this CRC CD-ROM was informed by a sociocultural approach to share health messages. Within this approach, cultural values, beliefs, and behaviors are affirmed as a place of wisdom and resilience and built upon to provide context and meaning for health messaging. Alaska Native values that honor family, relationships, the land, storytelling, and humor were included in CD-ROM content. Between January and May 2012, 20 interviews were conducted with individuals who had used the CD-ROM. Four categorical themes emerged from analysis of interview transcripts: likeability, utilization, helpfulness, and behavior change. As a result of self-paced learning through stories, movies, and interactive games, respondents reported healthy behavior changes they were making for themselves, with their families and in their patient care practices. This CD-ROM is a culturally based practical course that increased knowledge and activities around colorectal cancer screening by Community Health Aides/Practitioners in Alaska.

Headstrong intervention for pediatric migraine headache: a randomized clinical trial.

BACKGROUND: The purpose of this study was to evaluate the efficacy of a self-guided CD-ROM program ("Headstrong") containing cognitive-behavioral self-management strategies versus an educational CD-ROM program for treating headaches, headache-related disability, and quality of life. METHODS: Participants were 35 children ages 7-12 years with migraine recruited from one university medical center and two children's hospital headache clinics. Participants were randomly assigned to complete the Headstrong or educational control CD-ROM program over a 4-week period. Data on headache frequency, duration, and severity, migraine-related disability, and quality of life (QOL) were obtained at baseline, post-intervention, and 3-months post-intervention. RESULTS: At post-intervention, Headstrong resulted in lower severity (on a 10-point scale) than the control group by child report (5.06 ± 1.50 SD vs. 6.25 ± 1.92 SD, p = 0.03, ES = 0.7). At 3-months post-intervention, parents reported less migraine-related disability (on the PedMIDAS) in the Headstrong group compared to the control group (1.36 ± 2.06 SD vs. 5.18 ± 6.40 SD; p = 0.04, ES = 0.8). There were no other group differences at post treatment or at 3-months post-intervention. CONCLUSIONS: When compared to an educational control, Headstrong resulted in lower pain severity at post-treatment and less migraine-related disability at 3-months post-intervention, by child and parent report respectively. Headache frequency and quality of life did not change more for Headstrong versus control. Additional research is needed on the Headstrong Program to increase its efficacy and to test it with a larger sample recruited from multiple centers simultaneously.

Community health worker training for infant hearing health: effectiveness of distance learning.

OBJECTIVE: The purpose of this study was to evaluate the effectiveness of a distance training program in infant hearing health to community health workers (CHWs). DESIGN: Pre- and post- tests were administered to two groups of subjects following the use of an interactive CD-ROM for tele-educational training. STUDY SAMPLE: Two groups of subjects were used: Group I (GI) consisted of 43 CHWs who had previously participated in at least one training activity involving hearing health, and Group II (GII) were 47 CHWs who had received no prior training in hearing health. RESULTS: CHWs retained a significant amount of training content. There was not significant correlation between the global post-training questionnaire score and performance on the simulation activity (GI: r = 0.11, p = 0.698 and GII: r = 0.29, p = 0.074), and the simulation activity performance was significantly better among GI CHWs (p = 0.05). CONCLUSION: The CHWs' training in infant hearing health using an interactive tele-educational tool was effective, as the CHW demonstrated significant short-term information retention and applied such data in hypothetical situations representative of their daily activities.

The development of a CD-ROM: an aid to fetal cardiac diagnosis and counseling.

OBJECTIVE: Obstetric ultrasound allows for the fetal diagnosis of complex congenital heart disease, which once diagnosed is especially stressful for the affected parents. This study aimed to develop and pilot an educational CD-ROM for parents who had a fetal diagnosis of a congenital heart defect (CHD). MATERIAL AND METHODS: A CD-ROM was developed which included a brief description of a normal heart in text and cartoons, followed by one of five congenital heart abnormalities (again described in text and illustrated by cartoons highlighting the anatomy), the likely interventions (surgical or by catheter), and the local outcomes. A pilot study was conducted whereby parents were provided with the CD-ROM and asked to complete a brief evaluation following the fetal diagnosis of a suspected CHD and subsequent to counseling by the pediatric cardiologist, but prior to the birth of the infant. The CD-ROM was to be viewed at the parents' convenience. The questionnaire was returned via postal mail. RESULTS: A CD-ROM covering five common congenital heart abnormalities was successfully developed and distributed to 20 parents. Fourteen responses were received. The feedback was favorable. The parents found the CD-ROM to be informative and easily understood and supplemented the information previously provided by the pediatric cardiologist. The diagrams were particularly helpful. CONCLUSION: An educational CD-ROM describing a cardiac abnormality of a fetus was successfully created and favorably received, complementing the earlier counseling given. Further development of the CD-ROM with modifications highlighting parental suggestions and to include other abnormalities will allow for a wider audience.

[Digital X-ray: interhospital data transfer by CD-ROM. Prospective data evaluation during the import process]. / Digitales Röntgen: interhospitaler Datentransfer auf CD-ROM. Prospektive Datenevaluation während des Arbeitsprozesses.

BACKGROUND: Increasing numbers of radiological imaging diagnostics are archived in digital form. In addition to the results of diagnostics performed in hospital a growing number of patients present with digital results of outpatient radiological investigations. These digitized images represent a challenge for the internal hospital work flow. The aim of the study was to determine the expenditure for the hospital when dealing with digital outpatient diagnostic results. METHOD: Several parameters were observed and analyzed within the import process of nearly 400 CD-ROMs over a time period of 5 months. Only a negligible number of data on CD-ROMs could not be transferred into the hospital archive (1.5%). The duration of the process depended on the amount of data and the time period. RESULTS: During regular hours the import process took on average 13 min per CD and 19 min per patient while the time increased significantly during on-call duties. This study demonstrates the significance of the import of digital outpatient radiological diagnostic results into the hospital archive which can in particular influence patient treatment.

Emerging trends in the volume and format of outside examinations submitted for secondary interpretation.

OBJECTIVE: The purpose of this article is to describe the trends of secondary interpretations, including the total volume and format of cases. MATERIALS AND METHODS: This retrospective study involved all outside neuroradiology examinations submitted for secondary interpretation from November 2006 through December 2010. This practice utilizes consistent criteria and includes all images that cover the brain, neck, and spine. For each month, the total number of outside examinations and their format (i.e., hard-copy film, DICOM CD-ROM, or non-DICOM CD-ROM) were recorded. RESULTS: There was no significant change in the volume of cases (1043 ± 131 cases/month; p = 0.46, two-sided Student t test). There was a significant decrease in the volume of hard-copy films submitted, with the mean number of examinations submitted per month on hard-copy film declining from 297 in 2007 to 57 in 2010 (p < 0.0001, Student t test). This decrease was mirrored by an increase in the mean number of cases submitted on CD-ROM (753 cases/month in 2007 and 1036 cases/month in 2010; p < 0.0001). Although most were submitted in DICOM format, there was almost a doubling of the volume of cases submitted on non-DICOM CD-ROM (mean number of non-DICOM CD-ROMs, nine cases/month in 2007 and 17 cases/month in 2010; p < 0.001). CONCLUSION: There has been a significant decrease in the number of hard-copy films submitted for secondary interpretation. There has been almost a doubling of the volume of cases submitted in non-DICOM formats, which is unfortunate, given the many advantages of the internationally derived DICOM standard, including ease of archiving, standardized display, efficient review, improved interpretation, and quality of patient care.

Paediatric resuscitation training: is e-learning the answer? A before and after pilot study.

AIM: To determine whether an e-learning resuscitation programme was able to improve the knowledge and competence of doctors and nurses in providing cardiopulmonary resuscitation to children in a simulated cardiac arrest. METHOD: A prospective before and after pilot study comprising of a simulated paediatric resuscitation before and after participants undertook an e-learning programme. Participants were emergency department doctors and new graduate nurses from The Children's Hospital at Westmead, Australia. Primary outcome measures were the ability to perform successful basic life support (BLS) and advanced life support (ALS) according to published guidelines. Secondary outcome measures were the individual steps in performing the overall resuscitation and subjective feedback from participants. RESULTS: Fifty-six clinicians were enrolled in the study (29 doctors and 27 nurses). Thirty-seven were re-tested (25 doctors and 12 nurses). The mean time between tests was 49 days (17 standard deviation). The e-learning module led to an improvement in participants' ability to perform BLS by 51% (P < 0.001) and ALS by 57% (P= 0.001) overall resulting in an overall competence of 89% (BLS) and 65% (ALS). There were also significant improvements in time to rhythm recognition (P= 0.006), time to first defibrillation (P= 0.009) and participants' self-reported knowledge and confidence in BLS and ALS (P < 0.001). CONCLUSIONS: E-learning does improve both the knowledge and competence of doctors and nurses in providing cardiopulmonary resuscitation to children in the simulation environment.

Acceptability and preliminary feasibility of an internet/CD-ROM-based education and decision program for early-stage prostate cancer patients: randomized pilot study.

BACKGROUND: Prostate cancer is the most common cancer affecting men in the United States. Management options for localized disease exist, yet an evidence-based criterion standard for treatment still has to emerge. Although 5-year survival rates approach 98%, all treatment options carry the possibility for significant side effects, such as erectile dysfunction and urinary incontinence. It is therefore recommended that patients be actively involved in the treatment decision process. We have developed an Internet/CD-ROM-based multimedia Prostate Interactive Educational System (PIES) to enhance patients' treatment decision making. PIES virtually mirrors a health center to provide patients with information about prostate cancer and its treatment through an intuitive interface, using videos, animations, graphics, and texts. OBJECTIVES: (1) To examine the acceptability and feasibility of the PIES intervention and to report preliminary outcomes of the program in a pilot trial among patients with a new prostate cancer diagnosis, and (2) to explore the potential impact of tailoring PIES treatment information to participants' information-seeking styles on study outcomes. METHODS: Participants (n = 72) were patients with newly diagnosed localized prostate cancer who had not made a treatment decision. Patients were randomly assigned to 3 experimental conditions: (1) control condition (providing information through standard National Cancer Institute brochures; 26%), and PIES (2) with tailoring (43%) and (3) without tailoring to a patient's information-seeking style (31%). Questionnaires were administrated before (t1) and immediately after the intervention (t2). Measurements include evaluation and acceptability of the PIES intervention, monitoring/blunting information-seeking style, psychological distress, and decision-related variables (eg, decisional confidence, feeling informed about prostate cancer and treatment, and treatment preference). RESULTS: The PIES program was well accepted by patients and did not interfere with the clinical routine. About 79% of eligible patients (72/91) completed the pre- and post-PIES intervention assessments. Patients in the PIES groups compared with those in the control condition were significantly more likely to report higher levels of confidence in their treatment choices, higher levels of helpfulness of the information they received in making a treatment decision, and that the information they received was emotionally reassuring. Patients in the PIES groups compared with those in the control condition were significantly less likely to need more information about treatment options, were less anxious about their treatment choices, and thought the information they received was clear (P < .05). Tailoring PIES information to information-seeking style was not related to decision-making variables. CONCLUSIONS: This pilot study confirms that the implementation of PIES within a clinical practice is feasible and acceptable to patients with a recent diagnosis of prostate cancer. PIES improved key decision-making process variables and reduced the emotional impact of a difficult medical decision.

Formal reporting of second-opinion CT interpretation: experience and reimbursement in the emergency department setting.

The purpose of this study is to describe a system for formally reporting second-opinion interpretations of CT imaging exams accompanying patients transferred emergently to a tertiary care center. Second-opinion interpretations of cross-sectional imaging exams rendered in the emergency department setting over 6 months spanning 22 September 2009 to 22 March 2010 were reviewed and tallied by two radiologists and a research assistant, with a focus on professional fee reimbursement rates. A more in depth review was performed of those exams for which a clinical referral request form was available, detailing such information as the clinical history, content and source of available initial interpretation, and congruity of the initial interpretation with clinical data. Discrepancies between outside and second-opinion interpretations were also assessed. This quality assurance exercise was reviewed by our institutional review board, which waived formal informed consent. Formal second-opinion interpretation was rendered for 370 exams on 198 patients (mean age, 53.5 years; 45.1% female), received from 50 referring facilities. Head CT was the most common imaging exam referred for second opinion. Forty-one of 370 exams (11%) were submitted for self-pay, and 43 (12%) were written off as free care. The remaining 286 exams (77%) were submitted for reimbursement of the professional fee only. Ultimately, of the 286 exams submitted, 260 (91%) were reimbursed for professional fees, 199 (70%) on the initial submission. Of 29 health plans contracted with our facility, 22 ultimately approved all claims made. Three plans denied all claims submitted. The largest payer was Medicare, which reimbursed 88 of 90 submitted claims. Clinical intake forms were available for 184 exams on 107 patients (mean age, 52.7 years, 43.0% female). Trauma was the most common indication, or history, provided (55% of 184 exams, 40% of 107 patients). An outside report of some form was available for 112 of the 184 exams (61%), although only 18 were formal, signed radiology reports from the referring facility. Discrepancies between available outside reports and second-opinion interpretations were noted for 17 out of 112 exams. Need for reimaging was substantially curtailed, with only ten exams repeated within 24 h. A formal process for issuing second-opinion interpretations of cross-sectional exams performed at outside institutions is feasible in the emergency department setting. In the majority of cases, reimbursement for full professional fees can be obtained.

The effects of a human patient simulator vs. a CD-ROM on performance.

OBJECTIVES: Military health care personnel need to have skills relative to caring for patients on the battlefield. No studies have compared the two teaching strategies of using the human patient simulator (HPS) and a CD-ROM in caring for combat injuries. The objective of this study was to determine if there were statistically significant differences in HPS and CD-ROM educational strategies relative to caring for patients who have trauma. METHODS: A pretest/post-test prospective experimental design was used. Anesthesia students were randomly assigned to one of three groups: HPS, CD-ROM, or a control group. A valid and reliable instrument, Combat Performance, was used to evaluate the participant's ability to give care to trauma patients. RESULTS: A repeated analysis of variance and a least significant difference post hoc test were used to analyze the data. The HPS group performed better than the CD-ROM and control groups relative to performance (p = 0.001). There was no difference between the CD-ROM and control group (p = 0.171). DISCUSSION: We speculate that the HPS group performed better than the CD-ROM group because of the realism. CONCLUSION: In this study, the HPS method of instruction was a more effective method of teaching than the CD-ROM approach.

Development and pilot test of a culturally sensitive CD-ROM for hypertensive, older Chinese immigrants.

Hypertension control remains an issue for older Chinese immigrants because of the unique cultural health practices they use to manage their hypertension. Limited health education information on how to manage hypertension is available in Chinese. Because San Francisco has a large population of older Chinese immigrants, development of culturally sensitive educational material is important to help this population to achieve better blood pressure control. The purpose of this study was to develop and pilot test an innovative, culturally based CD-ROM with a focus on hypertension education and management, directed to the older Chinese immigrant population. The results of this pilot study found that the content of CD-ROM was culturally acceptable for the target population. Given a lack of educational material in Chinese in the United States, this CD-ROM has a potential to be used for a large population of Chinese elders in the United States.

Effects of using simulation versus CD-ROM in the performance of ultrasound-guided regional anesthesia.

The purpose of this study was to determine which method of teaching, CD-ROM, simulation, or a combination of both, was more effective in increasing the performance of ultrasound-guided regional anesthesia. No studies have investigated these methods. The framework for this study was critical thinking. The study was a prospective, mixed (between and within) subjects, experimental design. The sample consisted of 29 student registered nurse anesthetists randomly assigned to 1 of 3 groups: CD-ROM (n = 11), simulation (n = 11), and combination (n = 7). All groups were evaluated by the use of cadavers before and 2 months after the intervention using a valid and reliable instrument of performance. A repeated-measures analysis of variance indicated that the combination was significantly better than the CD-ROM and simulation (P < .05). The means and standard deviations for pretest and posttest results, respectively, were: CD-ROM, 33 +/- 7%, 41 +/- 9%; simulation, 35 +/- 10%, 49 +/- 13%; and combination, 36 +/- 8%, 64 +/- 17%. The baseline for each group was 0. Use of a combination of CD-ROM and simulation should be considered in teaching ultrasound-guided regional anesthesia techniques.

Can the 8-coil Shakti alter subjective emotional experience? A randomized, placebo-controlled study.

At present, a commercially available device (the 8-coil Shakti) claims to produce weak and complex magnetic fields that alter neurobiological processes. The effects of the Shakti on emotional responses to photographs that varied on emotional valence were investigated. Participants (N = 37) were exposed to either 30 min, of magnetic fields or a sham condition and rated their emotional reactions to a set of 54 color photographs. Although participants indicated significantly different emotional responses to images with distinct emotional valences, exposure to magnetic fields did not affect these responses, nor significantly interact with image emotional valence. Although the device's "amygdala signal" had no effect on the emotive response to images in this study, additional investigations examining the effects of weak and complex magnetic fields on various aspects of perception and cognition are warranted.
