Pattern of Right Ventricular Changes in Patients with Uncomplicated Systemic Hypertension at a Tertiary Centre in Southwest Nigeria

BACKGROUND AND AIMS

Hypertension is an independent risk factor for cardiovascular complications. The effect of systemic hypertension on the right ventricle (RV) has received less attention probably due to its complex structure and location. The aim of the study was to assess the effect of systemic hypertension on the structure and function of the right ventricle using transthoracic echocardiography.

METHOD

One hundred hypertensives and 100 healthy controls were recruited into the study. Transthoracic echocardiography was used to measure RV wall thickness (RVWT) in diastole, RV internal dimensions in diastole, tricuspid annular plane systolic excursion (TAPSE), right ventricular filling velocities (TE and TA), and RV systolic excursion velocity (RVSm). These measurements were repeated on the left ventricle.

RESULTS

There was significantly thicker RV wall (0.51 + 0.08cm vs 0.44+0.08cm; p=0.001) in the hypertensive group and higher frequency of RV hypertrophy (48.45% vs 18.75%; p<0.001). Tricuspid annular plane systolic excursion (TAPSE) and the tricuspid annular peak systolic excursion velocity (TSm) were significantly lower in the hypertensive group (2.34+0.45cm vs 2.50+0.36cm; p=0.008, and 11.70+3.03cm/s vs 12.60+2.93cm/s p=0.039, respectively), though no participant had abnormal TAPSE. Tricuspid E/A ratio was lower in the hypertensive group (1.13+ 0.33 vs 1.24+0.27; p=0.011). The tricuspid E/A ratio had positive correlation with mitral E/A ratio.

CONCLUSION

Right ventricular structural and functional changes are found in systemic hypertension, even in the absence of other systemic complications. These changes could have been mediated by ventricular interdependence and altered humoral factors.

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry

AIMS

The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation.

METHODS AND RESULTS

Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin.

CONCLUSION

The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Gender and the Digital Divide Across Urban Slums of New Delhi, India: Cross-Sectional Study

Background

Disparities in access to specific technologies within gender groups have not been investigated. Slum settings provide an ideal population to investigate the contributing factors to these disparities.

Objective

This study aimed to examine gender differences in mobile phone ownership, internet access, and knowledge of SMS text messaging among males and females living in urban slum settings.

Methods

A convenience sampling approach was used in sample selection from 675 unnotified slums. A total of 38 slum sites were then selected across four geographic zones. Of these, 10% of the households in each slum site was selected from each zone. One household member was interviewed based on their availability and fulfillment of the eligibility criteria. Eligible individuals included those aged 18 years and above, residing in these slums, and who provided voluntary consent to participate in the study. Individuals with mental or physical challenges were excluded from the study.

Results

Our results showed that females were half as likely to own mobile phones compared with males (odds ratio [OR] 0.53, 95% CI 0.37-0.76), less likely to have internet access (OR 0.79, 95% CI 0.56-1.11), or know how to send text messages (OR 0.93, 95% CI 0.66-1.31). The predictors of mobile phone ownership, internet access, and text messaging between males and females included age, individual education, housing type, and the number of earning members in a household in the adjusted analysis. Among males, the number of earning members was a predictor of both mobile phone ownership and text messaging, whereas household education was a predictor of both internet access and text messaging. Age and individual education only predicted internet access, whereas housing type only predicted text messaging. Among females, household education was a predictor of all the technology outcomes. Age and type of toilet facility only predicted mobile phone ownership; housing type only predicted internet access whereas television ownership with satellite service and smoking behavior only predicted text messaging.

Conclusions

Our study findings showing disparate access to technology within gender groups lend support for further research to examine the causal mechanisms promoting these differences to proffer significant solutions. Specifically, our study findings suggest that improving household education is crucial to address the disparate access and usage of mobile phones, the internet, and text messaging among women in slum settings. This suggestion is due to the consistency in household educational level as a predictor across all these technology indicators. In addition, the mechanisms by which the number of household earning members influences the disparate access to technology among men call for further exploration.

Comparison of Ideal Cardiovascular Health Attainment and Acculturation among Asian Americans and Latinos

Objective

To determine the association between language and ideal cardiovascular health among Asian Americans and Latinos.

Design/Study Participants

Cross-sectional study using 2011-2016 National Health and Nutrition Examination Survey of Asian Americans (n=2,009) and Latinos (n=3,906).

Interventions

Participants were classified according to language spoken at home (only/mostly English spoken, both English and native language spoken equally, or mostly/only native language spoken).

Outcomes

Ideal, intermediate and poor cardiovascular health status for smoking, blood pressure, glucose level, and total cholesterol.

Results

The majority of Asian Americans and Latinos had ideal smoking status, but those who only/mostly spoke English were more likely to smoke compared with those who spoke only/mostly spoke their native language. Approximately one third of Asian Americans and Latinos had intermediate (ie, borderline or treated to goal) levels of cardiovascular health for blood pressure, glucose level and total cholesterol. In adjusted models, those who spoke only/mostly their native language were significantly less likely to have poor smoking or hypertension status than those who spoke only/mostly English. Among Latinos, only/mostly Spanish speakers were more likely to have poor/ intermediate glucose levels (PR=1.35, 95% CI =1.21, 1.49) than those who spoke only/ mostly English, becoming statistically non-significant after adjusting for education and income.

Conclusion

We found significant variation in ideal cardiovascular health attainment by language spoken at home in two of the largest immigrant groups in the United States. Findings suggest the need for language and culturally tailored public health and clinical initiatives to reduce cardiovascular risk in diverse populations.

A human centered approach to design a diet app for patients with metabolic syndrome

BACKGROUND

The objective of this study was to utilize a human-centered approach in designing a diet app that would assist in management of patients with metabolic syndrome.

METHODS

A convenience sample of 10 dietetic interns (DIs) who were attending their informatics rotation at the City University of New York School of Public Health and Health Policy (CUNY GSPHHP) were recruited during October 2017. The study was conducted in two phases. In phase 1, the DIs received a tutorial on the use of human-centered approach in designing mobile health applications. In phase 2, the DIs were provided a case study for which they designed an app for patients to manage metabolic syndrome using a human centered approach. The goal of phase 2 was to identify the features that were believed to be most important when designing this metabolic syndrome app. An initial questionnaire was administered to the DIs to gather information on their socio-demographics, prior training in nutrition, smart phone usage, perceptions about food logs, and calorie intake calculations. Subsequent questionnaires gathered information from the DIs on their preferred diet app components, app features, rankings of the features, and mock representations of the diet app with the selected features.

RESULTS

The DIs were enrolled in the supervised practice component of their training to be Registered Dietitian Nutritionists (RDNs). Fifty percent of them had previously worked in a nutrition-related field. One-third of them were currently using a nutrition app. The top five features of the proposed diet app which the DIs identified as very important included (I) personalization of the app based on user preferences (80%, n=8); (II) disease specific education tips (90%, n=9); (III) ability to track progress (80%; n=8); (IV) reminders (70%, n=7) and (V) reinforcement based on user feedback (50%, n=5). In translating the identified features into functional requirements, majority of the DIs felt that the five key features identified should incorporate the following components: (I) personalization of the app should comprise information on medical factors, personal information, personal preferences, and recording weights; (II) disease specific educational tips should comprise information on food selections, low sodium options, and recipes for diabetes; (III) tracking progress should comprise features for storing audio files, viewing previous logs and uploading photos into a library; (IV) reminders should comprise daily messages to the users from the app; and (V) reinforcement should comprise provisions to enter motivational messages.

CONCLUSIONS

Our study lends support to the need for utilizing human-centered design (HCD) approaches in developing e-health dietary apps as well other non-diet related apps. App developers are encouraged to incorporate user characteristics, needs and preferences using a HCD framework that will allow for reproducibility, tailoring, user satisfaction, and effectiveness assessments.

Evaluating the Dietary and Nutritional Apps in the Google Play Store

Objectives

The objective of this study was to evaluate the features of diet and nutrition apps available in the Google Play Store.

Methods

A search was conducted in August 2017 using the Google Play Store database to identify apps related to diet and nutrition. Terms entered into the app search engine included 'diet apps' and 'nutrition apps'. The first 50 apps resulting from each search term was assessed. Duplicates were removed, and a comparative analysis was performed on the remaining diet and nutrition apps.

Results

A total of 86 diet and nutrition apps were identified. One hundred percent (n = 86) of the apps retrieved were freely available. More than half of the apps were applicable to a target user group of all ages (94%, n = 81). Stratified analysis across unique diet and nutrition apps (total, n = 72) showed a higher average rating for the diet apps (4.4) in comparison to that for the nutrition apps (4.3). Diet apps were more likely to be recently updated than the nutrition apps (72% vs. 66%), and diet apps were more likely to feature app purchase than nutrition apps (36% vs. 19%). The average rating was slightly higher for diet apps not featuring in-app purchases, but ratings were similar for the nutrition apps.

Conclusions

A centralized resource is needed that can provide information on health-related apps to allow for systematic evaluation of their effectiveness. Further research needs to examine improved methods of designing app-store platforms and presenting the available apps to properly guide users in app selection.

A Human-Centered Platform for HIV Infection Reduction in New York: Development and Usage Analysis of the Ending the Epidemic (ETE) Dashboard

BACKGROUND

Dashboards have been increasingly used in clinic-based interventions, such as clinical performance improvement and monitoring risk of hospital readmissions, and are now gaining traction in population-based interventions, especially in disease assessment.

OBJECTIVE

We describe the design, development, and usage analysis of a geovisualization dashboard, the Ending the Epidemic (ETE) Dashboard. The ETE dashboard is a tool developed to track New York's progress towards achieving the goal of its ETE Initiative, to reduce new HIV infections from 3000 per year to 750 per year by the end of 2020.

METHODS

The ETE dashboard was adapted from an existing human-centered geovisualization platform, SanaViz, an Internet-enabled, interactive app incorporating principles of human-centered design and cognitive fit theory to enhance visual exploration of population health data. Usage evaluation of the ETE geovisualization dashboard was conducted using Google Analytics over a 4-week period from March 19 to April 18, 2016. The aim was to monitor user activity and analyze traffic on the ETE dashboard using evidence-based metrics that can provide adequate feedback to enhance its utilization. Usage was characterized based on three metrics: (1) number of unique visits to each page, (2) average time on each page in seconds, and (3) page bounce rate (ie, percentage of visits where user left the site immediately after viewing just a single page). Further analysis was also conducted by cross-tabulating specific usage metrics.

RESULTS

Of 860 sessions, 324 sessions were initiated by unique users (37.7%). The most common acquisition channels included direct source (353/860, 41.0%); followed by referral traffic (340/860, 39.5%) and organic search (134/860, 15.5%). Usage statistics indicate that for the 860 sessions initiated by both new and returning users, the average viewing time was 8 minutes, 51 seconds, and the bounce rate was 46%. These statistics reflect positive results given that prior literature estimates an average session duration of 10-20 seconds and a bounce rate of 40-60% for most websites. Key findings from our study showed that the highest bounce rates were seen for the "About" page of the ETE website (65%), which describes the ETE initiative. The lowest bounce rates were seen for the ETE blog page (17%), consistent with prior research on website usage metrics that indicate that blog pages are often the most frequently viewed pages on Web portals.

CONCLUSIONS

Our findings reveal the potential of Google Analytics as a tool to enhance user traffic and performance of the ETE geovisualization platform by using feedback from regular monitoring of key parameters including page bounce rates and average time on page. It also identifies the need for a follow-up usability assessment of the system.

Blogs as Channels for Disseminating Health Technology Innovations

Objectives

The objective of this study was to describe the features of health informatics blogs on the Internet.

Methods

A search was conducted in August, 2016 using the search engine, Google, and key words: ‘mobile health blog,’ ‘telehealth/telemedicine blog,’ ‘Electronic Health Record blog,’ ‘personalized health record blog,’ ‘population health decision support system blog,’ and ‘public/population health dashboard blog.’ The first 24 blogs resulting from each key word search were recorded, generating 144 blogs. A total of 109 unique blogs resulted after removing duplicates and non-functional sites.

Results

Blogs with ‘.com’ extensions were most prevalent (72%, n = 79). More than half of the blogs (79%, n = 86) were created by industries. Mobile health (88%, n = 96), telehealth (82%, n = 89), and health IT (78%, n = 85) were the predominant topics covered. Health providers (44%, n = 48), industries (33%, n = 36), patients/consumers (25%, n = 27) and payers/insurance providers (19%, n = 21) constituted the most common target audience. Blogs catering to payers commonly used ‘.org’ extension (n = 10 out of 21), compared to ‘.com’ (n = 7) or ‘.gov’ (n = 2) (p < 0.0001). Significant differences were also observed by topics covered health IT (p = 0.007), subscription (p = 0.048) and LinkedIn social media (p = 0.019) across the website extensions.

Conclusions

Further research is needed to examine the use of blogs as channels of communication of best evidence in health informatics research among diverse stakeholders. The role of blogs as policy informatics tools need to be evaluated in order for stakeholders to collaborate, coordinate and share opportunities and challenges of various public health programs and policies.

Social and clinically-relevant cardiovascular risk factors in Asian Americans adults: NHANES 2011-2014

Little evidence exists examining cardiovascular risk factors among Asian Americans and how social determinants such as nativity status and education pattern risk in the United States (U.S.) context. We used the National Health and Nutrition Examination Survey, which purposely oversampled Asian Americans from 2011 to 2014, and examined prevalence of Type II diabetes, smoking and obesity for Asian Americans (n=1363) and non-Latino Whites (n=4121). We classified Asian Americans as U.S. or foreign-born and by years in the U.S. Obesity status was based on standard body mass index (BMI) cut points of ≥30kg/m² and Asian-specific cut points (BMI≥25kg/m²) that may be more clinically relevant for this population. We fit separate logistic regression models for each outcome using complex survey design methods and tested for the joint effect of race, nativity and education on each outcome. Diabetes and obesity prevalence (applying Asian-specific BMI cut points) were higher among Asian Americans when compared to non-Latino Whites but smoking prevalence was lower. These patterns remained in fully adjusted models and showed small increases with longer duration in the U.S. Joint effects models showed higher odds of prevalent Type II diabetes and obesity (Asian-specific) for foreign-born Asians, regardless of years in the U.S. and slightly higher risk for low education, when compared to non-Latino Whites with high education. Smoking models showed significant interaction effects between race and education for non-Latino Whites only. Our study supports the premise that social as well as clinical factors should be considered when developing health initiatives for Asian Americans.

Perception of receiving SMS based health messages among hypertensive individuals in urban slums

BACKGROUND

Hypertension rates are increasing in India, and prior research has not explored the perception of using mobile based SMS among urban hypertensive individuals living in slum settings in India.

OBJECTIVE

To explore the perception of receiving SMS based health messages among hypertensive individuals in urban slums.

METHODS

A cross sectional study was conducted during the period of December 2013 in an urban slum setting of South Delhi, New Delhi, India. Eligible study participants included: 45 individuals aged 30 years and above, with confirmed diagnosis of high blood pressure, owned a mobile phone/landline and were willing to participate.

RESULTS

Results of our study showed participants (n= 45) had an average age of 48 years (SD = 12), mostly female (64%, n= 29), and currently married (80%, n= 36). Their most common perceived hypertension risk factors included: worry/anxiety/stress (84%, n= 38), and high fat diet (68%, n= 30). Mobile calls were the most preferred mode of receiving lifestyle counseling among study participants (71%, n= 32). Majority preferred to receive counseling in Hindi language (67%, n= 30), and more than half were willing to pay for these services (60%, n= 27).

CONCLUSION

Our findings suggest the need for innovations that utilize basic phone platforms, mobile calling feature, and language tailored interventions.

Evaluation of a computer-based bilingual breastfeeding educational program on breastfeeding knowledge, self-efficacy and intent to breastfeed among rural Hispanic women

OBJECTIVE

To evaluate the impact of an interactive, computer based, bi-lingual breastfeeding educational program on breastfeeding knowledge, self-efficacy and intent to breastfeed among rural Hispanic women living in Scottsbluff, Nebraska.

METHODS

A two-group, repeated measures quasi-experimental study was conducted to evaluate the impact of a breastfeeding intervention. Forty six rural Hispanic women between ages 18 and 38 years were enrolled at the Regional West Medical Center in Scottsbluff, Nebraska. Study participants were randomized into intervention and control groups, with the intervention group (n=23) receiving bi-lingual (English and Spanish) breastfeeding education on a touch screen computer program, while the control group received printed educational material. Study participants were enrolled during their last six weeks of pregnancy, with follow up assessments conducted post-partum at days 3 and 7, weeks 2 and 6, and months 3 and 6. The study protocol was approved by the University of Nebraska Medical Center Institutional Review Board (IRB protocol #430-12-EP) and City University of New York Institutional Review Board (IRB protocol # 642980-1).

RESULTS

A significant improvement in the breastfeeding knowledge and intent to breastfeed scores was seen over a 6 month period among all the study participants (p<0.05). There was a gradual increase in the breastfeeding self-efficacy scores till week 6 followed by a decrease in self-efficacy scores at month 3 (p=0.46), and month 6 (P=0.54). Breastfeeding knowledge scores differed significantly between the study participants in the control and intervention groups at week 6 (p=0.03). There were no significant differences in the breastfeeding knowledge between the control and intervention groups at other time points. The control group showed gradual decline in their self-efficacy scores at month 3 and month 6 compared to the intervention group that showed a gradual increase in their self-efficacy scores at different time points during their follow up period. However, there were no significant differences in the self-efficacy scores between the intervention and control groups at different points. The control group showed significantly higher negative breastfeeding sentiment scores compared to the intervention group at days 3 (p=0.02) and 7 (p=0.03) indicating a lower intent to breastfeed.

CONCLUSION

Hispanic women living in rural settings showed improvement in breastfeeding knowledge, self-efficacy and intent to breastfeed using the computer based bi-lingual educational program. Results show week 6 and month 3 to be the critical time points of intervention so that women continue to breastfeed.

Assessing public health job portals over the internet

AIMS

The objective of our study was to search existing public health job websites over the internet and describe the challenges related to finding these job websites.

METHOD

An internet search was conducted using different search engines, including Google, Yahoo and Bing, with several keywords including: Public Health Jobs, Epidemiology Jobs, Biostatistics Jobs, Health Policy and Management Jobs, Community Health Jobs, Health Administration Jobs, Nutrition Jobs, Environmental and Occupational Health Science Jobs, GIS Jobs, and Public Health Informatics Jobs. We recorded the first 20 websites that appeared in the results of each keyword search, thus generating 600 URLs. Duplicate sites and non-functional sites were excluded from this search, allowing analysis of unique sites only.

RESULTS

The initial search resulted in 600 websites of which there were 470 duplicates. More than half of the website categories were ".com" (54%; n = 323) followed by ".gov" (19%; n = 111) and ".edu" 15% (n = 90). Results of our findings showed 194 unique websites resulting from a search of 600 website links. More than half of them had actual public health or its related jobs (56%; n = 108).

CONCLUSION

There is a need to establish standard occupational classification categories for the public health workforce.

The Nutrition and Dietetics Workforce Needs Skills and Expertise in the New York Metropolitan Area

Background:

There is an increased demand in the Nutrition and Dietetics field which has fostered credentialing to ensure competent graduates. The objective of this study is to conduct an exploratory analysis to identify nutrition/dietetics workforce needs, skills and expertise in the New York metropolitan area as exemplified in position announcements over a 4 year period.

Methods:

We recorded position announcements for jobs in nutrition and dietetics from the New York State Registered Dietitian Yahoo group, and the Hunter College Nutrition and Food Sciences student and alumni listserv (NFS-L) over a 4 year period. Keywords were identified using job categories defined by the Academy of Nutrition and Dietetics (AND) compensation and benefits survey. This served as a starting point to enumerate the types of positions that have been posted for the New York metropolitan area in recent years.

Results:

Four hundred and twelve (412) unique job postings were recorded. Various educational levels, credentials, and skills desired by these employers were identified, assessed, and compared with similar data from the “supply side” reports from AND.

Conclusions:

The credentials and skills most desired by employers are similar to some of the learning objectives set forth for DPD and DI programs by ACEND, but not entirely congruent. The need for both client/customer focus and computer literacy may be implicit in the standards, but a more overt inclusion of these skills would likely be of benefit to ensure these are inculcated into every program and student.

Evaluating the usability of an interactive, bi-lingual, touchscreen-enabled breastfeeding educational programme: application of Nielson's heuristics

The study purpose was to conduct heuristic evaluation of an interactive, bilingual touchscreen-enabled breastfeeding educational programme for Hispanic women living in rural settings in Nebraska. Three raters conducted the evaluation during May 2013 using principles of Nielson's heuristics. A total of 271 screens were evaluated and included: interface (n = 5), programme sections (n = 223) and educational content (n = 43). A total of 97 heuristic violations were identified and were mostly related to interface (8 violations/5 screens) and programme components (89 violations/266 screens). The most common heuristic violations reported were recognition rather than recall (62%, n = 60), consistency and standards (14%, n = 14) and match between the system and real world (9%, n = 9). Majority of the heuristic violations had minor usability issues (73%, n = 71). The only grade 4 heuristic violation reported was due to the visibility of system status in the assessment modules. The results demonstrated that the system was more consistent with Nielsen's usability heuristics. With Nielsen's usability heuristics, it is possible to identify problems in a timely manner, and help facilitate the identification and prioritisation of problems needing urgent attention at an earlier stage before the final deployment of the system.

Role of music in the management of chronic obstructive pulmonary disease (COPD): a literature review

INTRODUCTION

Chronic obstructive pulmonary disease (COPD) is a pulmonary disease characterized by airflow limitation that is not fully reversible. It is projected to be the third leading cause of death worldwide by 2020. The objective of the study was to examine the impact of music on psychological and physiological outcomes among individuals with COPD.

METHODS

The scientific databases PubMed, google scholar and EBSCO were used to search for relevant articles published during a period of 01/01/2005 to 12/31/2012. The search terms "Music and COPD", "Music and Emphysema", "Singing and COPD", "Singing and Emphysema" , "music improves COPD" and "singing therapy on COPD", were used either in single or in combination. The inclusion criteria included studies having an experimental study design, were written in English and were conducted among individuals age 18 years and above. Studies that focused on the healthy population or had a disease other than COPD were excluded. Studies where music therapy was not the primary intervention and were systematic reviews were also excluded from the final analysis. Variables analyzed included year of publication, study location, study setting, target audience, study design, sample size, study duration, intervention and its components and the outcomes including physiological and psychological were assessed.

RESULTS

A total of 7 papers that met the inclusion criteria were included in the final analysis. Studies included various music interventions such as singing, listening and playing music. Forty percent of the studies were performed in US. More than half of the studies (70%, n=5) had a randomized control study design and were performed in a hospital setting. The duration of the studies varied from 6 weeks to 21 months. The sample size in these studies varied from 7 to 72. Music showed improvement in the psychological outcomes such as quality of life, dyspnea and anxiety and mixed results in the improvement of physiological outcomes such as FEV, FVC, and breathing control among individuals living with COPD.

DISCUSSION

More research of a longer duration and with a larger sample size is needed to examine the impact of music interventions on clinical, functional, psychological and physiological outcomes among COPD individuals.

Perceptions of online lifestyle counseling among individuals living in rural India

The burden of lifestyle related chronic diseases have increased in recent times. The objective of this pilot study was to explore perceptions about using online lifestyle counseling services among individuals living in rural settings in India. A pilot convenient sample of 100 individuals living in rural settings of Chennai with age 18 years and above was enrolled for the study. Information was gathered about socio-demographic characteristics, health behavior, current disease status; familiarity with technology and perceptions about online lifestyle counseling. The average age of the individuals was 34 years (SD=15). More than half of the individuals had access to computers at home and workplace. Individuals indentified various barriers for unable to obtain lifestyle counseling. Nearly 47% of the individuals were interested in obtaining online lifestyle counseling. There is an urgent need for evaluating the role of an online lifestyle counseling intervention among individuals living in rural settings.

Evaluation of an interactive surveillance system for monitoring acute bacterial infections in Nigeria

OBJECTIVE

The objective of the study is to evaluate the usability of a stand-alone, Internet-enabled interactive surveillance system designed to monitor the burden of invasive bacterial infections among children in Nigeria.

METHOD

A convenience sample of 10 participants were enrolled in a training session on using the system at a hospital in Nigeria. The participants performed a series of tasks assessing their ability to use the system. System usability was assessed using a System Usability Scale (SUS) questionnaire.

RESULTS

The majority of participants found the system easy to use (90 percent; n = 9) and reported confidence in using the system. The average SUS score was 77.8. A total of 30 percent (n = 3) of the study participants had exceptional usability scores, 20 percent (n = 2) showed acceptable scores, and 10 percent (n = 1) had a good score.

CONCLUSION

Further evaluation of the system will help gauge additional challenges during its long-term utilization. If successful, the system could also be deployed in other resource poor-environments.

An interactive, bilingual touch screen program to promote breastfeeding among Hispanic rural women: usability study

Background

Computer technology can be effectively used to educate patients and improve knowledge and attitudes, leading to healthier behavior. Among rural women, breastfeeding outcomes seem to be worst compared to women living in urban areas. The implementation of a bilingual computer mediated health education program to disseminate information and improve outcomes among users with low literacy levels has proven to be successful.

Objective

The objective of this pilot study was to examine the usability of an interactive, bilingual touch screen computer-based educational program to promote breastfeeding practices among Hispanic women living in rural settings.

Methods

A convenience sample of 10 Hispanic rural women at the Regional West Medical Center (RWMC), Scottsbluff was enrolled during May 2013. Information about this cross-sectional study was made available through the flyers at the RWMC. A brief introduction of the prototype was given and study subjects were then asked to complete a predefined set of tasks by interacting with the prototype. Users were assigned 6 tasks and information was gathered about the time taken to complete the tasks, number of attempts, and if assistance was needed. Notes and test sessions were audiotaped. Usability assessment was performed using the System Usability Scale (SUS).

Results

The mean age of the study participants was 28 years (SD 3.6), the majority of them had 12 or more years of education (90%, 9/10), and 60% (6/10) had breastfed less than 6 months. There were 90% (9/10) of the study participants that had no prior history of taking prenatal classes and 80% (8/10) that did not intend to take any prenatal classes in the future. The average SUS scores were 90 and SD was 10.5. There were three participants that had average SUS scores of 100, followed by scores of 97.5 (1/10), 95 (1/10), 87.5 (1/10), 85 (2/10), 82.5 (1/10), and one participant had a score of 67.5 (1/10). No assistance was needed to complete any of the tasks.

Conclusions

The study participants were able to navigate through the multimedia program with ease and obtain relevant breastfeeding related health information. The interactive, touch screen computer-based breastfeeding program had high acceptance among 10 Hispanic women living in rural settings.

Evaluation of sperm nuclear morphology in specimens with abnormal sperm chromatin structural assays

Two recent tests have claimed to identify the subfertile male even when other semen parameters were normal: the sperm chromatin structure assay (SCSA) and abnormal sperm nuclear morphology using much higher magnification. The present study attempted to determine if having a high (> 30%) DNA fragmentation index (DFI), thus resulting in an abnormal SCSA test, is associated with a greater likelihood of sperm with abnormal nuclei. Four males with high DFI scores (57.6%, 65.4%, 31.0%, and 35.3%) had their nuclei evaluated by a complex microscope set-up that magnifies the sperm at least 6000x. The corresponding % of normal nuclei was 0%, 20.0%, 23.7% and 40.0%. The mean and median % of normal nuclei was 20.9+/-16.43 and 21.8, respectively. More studies of similarly matched refractory in vitro fertilization cases, where males have normal DFI scores, are needed to determine if having a high DFI index is associated with a lower percentage of normal nuclei.

The treatment of idiopathic edema, a cause of chronic pelvic pain in women: effectively controlled chronic refractory urticaria--case reports

PURPOSE

To corroborate or refute a previous case report from 20 years ago whether treatment with sympathomimetic amines is effective in controlling chronic urticaria.

METHODS

All cases of chronic urticaria in our reproductive endocrinology and infertility practice were identified. All four had been treated with dextroamphetamine sulfate. Quickness and duration of response were then determined.

RESULTS

Four women were identified. All showed improvement within the first month. The marked improvement did not dissipate including two patients whose duration of improvement was 8.5 and 13 years, respectively.

CONCLUSIONS

Gynecologists should consider idiopathic edema as an etiology when facing chronic pelvic pain and urticaria. Since allergists and dermatologists do not seem to be aware of this treatment option, the initiation of therapy may need to come from the gynecologist.
