Research that investigates standalone effects of a mobile phone-based cognitive behavioral therapy without any human contact for reducing both psychological distress and risky drinking has been advancing; however, the number of studies is still limited. A mobile phone app called Self Record that facilitates cognitive restructuring through self-monitoring of daily thoughts and activities was developed in Japan. This study conducted a nonrandomized controlled pilot trial of the Self Record app to investigate standalone effects of the intervention on psychological distress and alcohol consumption among Japanese workers. Additionally, we examined moderating effects of negative mood regulation expectancies, which are beliefs about one's ability to control one's negative mood. A quasi-experimental design with a 1-month follow-up was conducted online in Japan from February 2016 to March 2016. A research marketing company recruited participants. The selection criteria were being a Japanese full-time worker (age 20-59 years), experiencing mild to moderate psychological distress, and having some interest in self-record apps. Assignment to group was based on participants' willingness to use the app in the study. All participants completed outcome measures of negative mood regulation expectancies, positive well-being, general distress, depression, anxiety, and typical/most weekly alcohol consumption. From the recruitment, 15.65% (1083/6921) of participants met the inclusion criteria. Of these, 51.43% (557/1083) enrolled in the study: 54.9% (306/557) in the intervention group and 45.1% (251/557) in the control group. At the 1-month follow-up, 15.3% (85/557) of participants had dropped out. Intention-to-treat analyses revealed that participants in the intervention group reported increased typical drinking (η2=.009) and heavy drinking (η2=.001). Adherence to using the app was low; 64.8% (199/306) of participants in the intervention group discontinued using the app on the first day. Additionally, 65.7% (366/557) of the total sample did not correctly answer the validity checks in the outcome measures (eg, "Please select 'mildly agree' for this item"). Therefore, per-protocol analyses were conducted after removing these participants. Results showed that continuing app users (42/127) in the intervention group reported increases in anxiety (η2=.006), typical drinking (η2=.005), and heavy drinking (η2=.007) compared to those in the control group (85/127). Negative mood regulation expectancies moderated the effects of the intervention for general distress (beta=.39). Results were contrary to our hypotheses. Self-recording methods of standalone mobile phone interventions may heighten individuals' awareness of their pathological thought and drinking behavior, but may be insufficient to decrease them unless combined with a more intense or face-to-face intervention. Limitations include high attrition in this study; measures to improve the response rate are discussed. ©Toshitaka Hamamura, Shinichiro Suganuma, Mami Ueda, Jack Mearns, Haruhiko Shimoyama.

Although increasing attention is paid to HIV/AIDS, patients with HIV still experience several barriers to self-care. These barriers have been previously identified in small quantitative studies on women with HIV, but qualitative studies are required to clarify barriers to self-care. We conducted our study using the grounded theory methodological approach. A total of 28 women with HIV and their family members, were interviewed. The data were analyzed with the Corbin and Strauss method (1998). The key barriers to self-care in women with HIV/AIDS included social stigma, addiction, psychological problems, medication side-effects and financial problems. Women with HIV/AIDS face several barriers to self-care. Therefore, when designing self-care models for these women, social and financial barriers should be identified. Mental health treatment should also be incorporated into such models and patients' access to health care services should be facilitated.

The lived experience of self-transcendence in women with AIDS.

To describe the lived experience of self-transcendence in women with AIDS, associated with increased sense of meaning and purpose, well-being, self-esteem, and connectedness with self and/or others. Exploratory-descriptive, using phenomenological research methods for the study approach, data collection, and data analysis. One written description and nine audiotaped interviews of self-transcendence experiences were provided by women with class IV HIV infection (AIDS). Ten women recruited by nurses at an AIDS family clinic and through a flyer at the AIDS Support Group House in Seattle. Participant descriptions indicated that women with AIDS continue to find meaning and purpose in their lives through experiences of receiving from others, giving to others, and maintaining hope. The findings support the theory that self-transcendence views and behaviors are a source of mental health at the end of life. The findings suggest several ways nurses may help women with AIDS discover or make meaning and purpose in their lives.

This study explored responsibility attribution (RA) of HIV/AIDS infection (i.e., how an individual perceives the cause of their HIV/AIDS infection) and its relationship to coping styles among injection drug users (IDUs) with HIV/AIDS. In addition, this study investigated whether self-esteem, social support, and religiosity mediate the relationship between RA and coping styles of IDUs with HIV/AIDS. Participants were 201 adult IDUs with HIV/AIDS participating in the National Drug Rehabilitation Center in Malaysia. Five measures were used to assess the above constructs. Cluster analysis, analysis of variance, and mediation analyses were conducted. Results of this study indicated that IDUs with HIV/AIDS in Malaysia can be classified into four homogenous attribution groups: external, fatalistic, internal, and indeterminate. Mediator analyses revealed that combination of self-esteem, social support, and religiosity mediate the relationship between RA and coping behaviors. Clinicians working with IDUs with HIV/AIDS need to address the role of RA, self-esteem, religiosity, and social support as these psychosocial constructs are linked to coping with HIV/AIDS. Future researchers should investigate whether enhancing self-esteem, social support, and religiosity can promote active problem-solving coping and reduce the use of avoidance coping behaviors.

Recursive feedback is defined and discussed as a framework for development of specific algorithms and procedures that propagate the time-domain solution for a dynamical system simulation consisting of multiple numerically coupled self-contained stand-alone subsystem simulations. A satellite motion example containing three subsystems (other dynamics, attitude dynamics, and aerodynamics) has been defined and constructed using this approach. Conventional solution methods are used in the subsystem simulations. Centralized and distributed versions of coupling structure have been addressed. Numerical results are evaluated by direct comparison with a standard total-system simultaneous-solution approach.

This study examines the effectiveness of a HIV/AIDS peer education program, Teens for AIDS Prevention (TAP) in two cultures. A convenience sample of 287 (American and Nepalese) 9th grade students participated in the study. It was found that HIV/AIDS knowledge scores were significantly higher among American adolescents than their Nepalese counterparts only at pre-intervention. American adolescents had significantly higher self-efficacy scores than Nepalese adolescents both at pre-intervention and post-intervention. Adolescent peer education programs could be used to improve adolescent HIV/AIDS knowledge and self-efficacy for limiting sexual risk behavior; however for the educational programs to be effective, it is pertinent that the program is culturally appropriate to the target population.

Self-transcendence and depression among AIDS Memorial Quilt panel makers.

Kausch, Kurt D; Amer, Kim

2007-06-01

Self-transcendence is a process that can help individuals reestablish well-being after experiencing a significant, life-altering event. In this study, we sought to identify the relationship between self-transcendence and depression in individuals who lost loved ones to HIV/AIDS and to describe and compare self-transcendence, self-transcendence variables of acceptance and spirituality, and depression among bereaved individuals who created AIDS Memorial Quilt panels with those who did not. The findings support Reed's self-transcendence theory, with inverse correlations between self-transcendence and depression obtained from both the total group and the panel makers. Significant differences were also found between certain self-transcendence variables and depression among the study participants related to gender and ethnicity. In addition, thematic analysis of panel maker interviews revealed five themes: Quilt panel making provides validation, Quilt panel making creates a living memory, liberating acceptance of loss, community of survivors, and connection to a higher power. These findings assist in understanding the complexities of the grief process and support the usefulness of Quilt panel making as an intervention for coping with grief related to HIV/AIDS.

African American women are the most rapidly growing group of people in the United States diagnosed with HIV/AIDS. The purpose of this study was to explore experiences of self-care and mothering among African American women with HIV/AIDS. It is important to recognize how culture affects illness management, childrearing, and daily living to design culturally appropriate nursing interventions for African American women. Critical ethnography was used to study 10 African American mothers from the rural Southeast who were HIV positive and mothered children who were HIV positive. Domains derived from the research were disabling relationships, strong mothering, and redefining self-care. The cultural theme was creating a life of meaning. African American mothers with HIV/AIDS in the rural Southeast used culturally specific self-care and mothering strategies reflective of cultural traditions. This study acknowledges strengths of African American women and generates theory that will enhance nursing care to this population.

By 2015, one-half of all HIV-positive persons in the U.S. will be 50-plus years of age, and as many as 30 % of older adults living with HIV/AIDS continue to engage in unprotected sexual intercourse. Contemporary positive prevention models often include mental health treatment as a key component of HIV prevention interventions. This secondary data analysis characterized longitudinal patterns of sexual behavior in HIV-positive older adults enrolled in a randomized controlled trial of group mental health interventions and assessed the efficacy of psychosocial treatments that targeted depression to reduce sexual risk behavior. Participants were 295 HIV-positive adults ≥50 years of age experiencing mild to severe depressive symptoms, randomized to one of three study conditions: a 12-session coping improvement group intervention, a 12-session interpersonal support group intervention, or individual therapy upon request. Approximately one-fifth of participants reported one or more occasions of unprotected anal or vaginal intercourse with HIV-negative sexual partners or persons of unknown HIV serostatus over the study period. Changes in sexual behavior did not vary by intervention condition, indicating that standalone treatments that target and reduce depression may be insufficient to reduce sexual risk behavior in depressed HIV-positive older adults.

McMullan, Alexandra; Kelly-Campbell, Rebecca J; Wise, Kim

2018-03-08

This pilot study aimed to investigate whether revising a hearing aid user guide (HAUG) is associated with improved hearing aid self-efficacy and utility performance. In Part 1, an HAUG was evaluated using the Suitability Assessment of Material (SAM) and readability formulas (Flesch Reading Ease [Flesch, 1943], Flesch-Kincaid Readability Formula [Kincaid, Fishburne, Rogers, & Chissom, 1957], and Simple Measure of Gobbledygook [McLaughlin, 1969]). The HAUG was revised using results from the SAM and best practice guidelines. The revision included generating a video. In Part 2, 30 adults with hearing impairment were randomly assigned to use either the original guide (N = 15) or the revised guide and video (N = 15) to perform a utility task. Participants' self-efficacy was measured using the Basic and Advanced Handling subscales of the Measure of Audiologic Rehabilitation Self-Efficacy for Hearing Aids questionnaire. SAM and readability were compared between the original and revised guides (Doak, Doak, & Root, 1996). SAM and readability were improved following the revision. Participants in the revised guide group performed significantly better on the utility task and on the Measure of Audiologic Rehabilitation Self-Efficacy for Hearing Aids subscales than participants in the original guide group. These results are encouraging as they indicate that there is scope to influence self-efficacy and utility performance through the use of appropriate HAUGs.

In India in 2009, it was estimated that 2.4 million people were living with HIV, which equates to a prevalence of 0.3 percent. While this seems low, because India's population is so large, this rate is third in the world in terms of the absolute number of people living with HIV/AIDS. This study evaluated the self-esteem and quality of life of people living with HIV/AIDS in the Indian population using a correlational design. A significant positive correlation between self esteem and the different dimensions of quality of life was established. Interventions designed for people with HIV/AIDS could well include self esteem as a moderator of quality of life. © The Author(s) 2013.

This study used self-reports and physiological measures-heart rate (HR) and skin conductance level (SCL)-to examine the effects of novelty appeals, sexual appeals, narrative versus statistical evidence, and viewer's sex on cognitive and emotional processing of HIV/AIDS public service announcements (PSAs) among heterosexually active single college students. Novelty or sexual appeals differently affected self-reported attention and cognitive effort as measured by HR. High- rather than low-novelty HIV/AIDS PSAs, perceived as more attention-eliciting, did not lead to more cognitive effort. High- rather than low-sex HIV/AIDS PSAs, not perceived as more attention-eliciting, led to more cognitive effort as reflected by greater HR deceleration. Novelty or sexual appeals also affected self-reported emotional arousal and SCL differently. HIV/AIDS PSAs with high rather than low levels of novelty or sexual appeals led to greater self-reported arousal, but not greater SCL. Message evidence interacted with message appeals to affect cognitive effort. Participants exerted greater cognitive effort during high- rather than low-novelty narrative HIV/AIDS PSAs, and during low- rather than high-novelty statistical ones. The advantage of high over low sexual appeals was more obvious in statistical than in narrative HIV/AIDS PSAs. Males reported greater emotional arousal than females during high- rather than low-sex HIV/AIDS PSAs.

Investigating previous studies show that personality traits have an important role in controlling risky behaviours related to AIDS; therefore, the aim of this study is to investigate the relationship between AIDS health literacy, personality traits and mental health and controlling risky behaviours related to AIDS through self-efficacy. The statistical population includes all the young people in western provinces of Iran, 2015. Data analysis was carried out for a sample of 756 participants (59% female). The results show that except for the socializing trait, all the other variables are related to controlling risky behaviours. In addition, variables of health literacy related to AIDS, mental health, activity, impulsive sensation seeking and hostility have a direct relation to controlling risky behaviours. Also, the predicting behaviours can predict 62% of the variance in controlling risky behaviours related to AIDS. The analysis results show that health literacy has an indirect impact on controlling risky behaviours through self-efficacy. In other words, health literacy related to AIDS leads to controlling risky behaviours when self-efficacy is high for controlling risky behaviours. Based on the results, it is recommended that the role of self-efficacy in controlling risky behaviours be considered as a strategy for preventing AIDS. Copyright © 2016 John Wiley & Sons, Ltd.

In children, otitis media with effusion is treated using grommets or hearing aids. Parents considering treatment options express concerns regarding the psychosocial impact of hearing aids in terms of self-esteem and bullying. This study assessed the psychosocial impact of hearing aid use. A cross-sectional study was undertaken comparing hearing aid users to non hearing aid users with regard to their attitudes towards hearing aids. All subjects, who had been diagnosed with otitis media with effusion, were aged less than 16 years, were without disability and attended mainstream schools. A questionnaire was designed and utilised. The study comprised 47 children with hearing aids and 50 with grommets. Significant between-group differences (p < 0.05) were noted with regard to perceptions related to bullying, feelings of inadequacy and embarrassment. The overall negative perceptions of non hearing aid users were not reported by hearing aid users. Children with hearing aids do not suffer from bullying or low self-esteem to the extent perceived by parents. This information is useful for informed decisions regarding treatment of otitis media with effusion.

Physiotherapist prescribed self-management strategies are an important adjunct to 'hands on' treatment. However, treatment outcomes are likely to be related to whether patients adhere to the prescribed strategy. Therefore, physiotherapists should be aware of adherence aiding interventions designed to maximise patient outcomes underpinned by quality research studies. To conduct a systematic review of the interventions used to aid patient adherence to all physiotherapist prescribed self-management strategies. The search included the databases CINAHL, EMBASE, MEDLINE, PUBMED, PSYCINFO, SPORTSDiscus, the Cochrane Central Register of Controlled Trials, PEDro and Mednar for randomised controlled trials (RCTs) published in a peer reviewed journal from inception to November 2014. Data were extracted using a standardised form from twelve included RCTs for patient adherence rates to self-management strategies for interventions used to aid patient adherence and usual care. Two independent reviewers conducted methodological quality assessment. Twelve different interventions to aid patient adherence to exercise were recorded from twelve fair to high quality RCTs. Potential adherence aiding interventions include an activity monitor and feedback system, written exercise instructions, behavioural exercise programme with booster sessions and goal setting. Despite a number of studies demonstrating interventions to positively influence patient adherence to exercise, there is insufficient data to endorse their use in clinical practice. No RCTs examining adherence aiding interventions to self-management strategies other than exercise were identified, indicating a significant gap in the literature. PROSPERO CRD42015014516.

2015-01-01

Multi-agent systems (MAS) can be used for decentralized and self-organizing data processing in a distributed system, like a resource-constrained sensor network, enabling distributed information extraction, for example, based on pattern recognition and self-organization, by decomposing complex tasks in simpler cooperative agents. Reliable MAS-based data processing approaches can aid the material-integration of structural-monitoring applications, with agent processing platforms scaled to the microchip level. The agent behavior, based on a dynamic activity-transition graph (ATG) model, is implemented with program code storing the control and the data state of an agent, which is novel. The program code can be modified by the agent itself using code morphing techniques and is capable of migrating in the network between nodes. The program code is a self-contained unit (a container) and embeds the agent data, the initialization instructions and the ATG behavior implementation. The microchip agent processing platform used for the execution of the agent code is a standalone multi-core stack machine with a zero-operand instruction format, leading to a small-sized agent program code, low system complexity and high system performance. The agent processing is token-queue-based, similar to Petri-nets. The agent platform can be implemented in software, too, offering compatibility at the operational and code level, supporting agent processing in strong heterogeneous networks. In this work, the agent platform embedded in a large-scale distributed sensor network is simulated at the architectural level by using agent-based simulation techniques. PMID:25690550

2018-02-01

Self-monitoring (SM) of diet and tailored feedback (TF) have been suggested as tools for changing dietary behavior. New technologies allow users to monitor behavior remotely, potentially improving reach, adherence, and outcomes. We conducted a systematic literature review and meta-analysis to address the following question: are remotely delivered standalone (i.e., no human contact) interventions that use SM or TF effective in changing eating behaviors? Five databases were searched in October 2016 (updated in September 2017). Only randomized controlled trials published after 1990 were included. Trials could include any adult population with no history of disordered eating which delivered an SM or TF intervention without direct contact and recorded actual dietary consumption as an outcome. Three assessors independently screened the search results. Two reviewers extracted the study characteristics, intervention details, and outcomes, and assessed risk of bias using the Cochrane tool. Results were converted to standardized mean differences and incorporated into a 3-level (individuals and outcomes nested in studies) random effects meta-analysis. Twenty-six studies containing 21,262 participants were identified. The majority of the studies were judged to be unclear or at high risk of bias. The meta-analysis showed dietary improvement in the intervention group compared to the control group with a standardized mean difference of 0.17 (95% CI: 0.10, 0.24; P < 0.0001). The I2 statistic for the meta-analysis was 0.77, indicating substantial heterogeneity in results. A "one study removed" sensitivity analysis showed that no single study excessively influenced the results. Standalone interventions containing self-regulatory methods have a small but significant effect on dietary behavior, and integrating these elements could be important in future interventions. However, there was substantial variation in study results that could not be explained by the characteristics we explored, and there were risk-of-bias concerns with the majority of studies.

ABSTRACT Background Self-monitoring (SM) of diet and tailored feedback (TF) have been suggested as tools for changing dietary behavior. New technologies allow users to monitor behavior remotely, potentially improving reach, adherence, and outcomes. Objective We conducted a systematic literature review and meta-analysis to address the following question: are remotely delivered standalone (i.e., no human contact) interventions that use SM or TF effective in changing eating behaviors? Design Five databases were searched in October 2016 (updated in September 2017). Only randomized controlled trials published after 1990 were included. Trials could include any adult population with no history of disordered eating which delivered an SM or TF intervention without direct contact and recorded actual dietary consumption as an outcome. Three assessors independently screened the search results. Two reviewers extracted the study characteristics, intervention details, and outcomes, and assessed risk of bias using the Cochrane tool. Results were converted to standardized mean differences and incorporated into a 3-level (individuals and outcomes nested in studies) random effects meta-analysis. Results Twenty-six studies containing 21,262 participants were identified. The majority of the studies were judged to be unclear or at high risk of bias. The meta-analysis showed dietary improvement in the intervention group compared to the control group with a standardized mean difference of 0.17 (95% CI: 0.10, 0.24; P < 0.0001). The I2 statistic for the meta-analysis was 0.77, indicating substantial heterogeneity in results. A “one study removed” sensitivity analysis showed that no single study excessively influenced the results. Conclusions Standalone interventions containing self-regulatory methods have a small but significant effect on dietary behavior, and integrating these elements could be important in future interventions. However, there was substantial variation in study results that could not be explained by the characteristics we explored, and there were risk-of-bias concerns with the majority of studies.

Study Design: Retrospective cohort study. Objective: To compare perioperative characteristics of stand-alone cages and anterior cervical plates used for anterior cervical discectomy and fusion (ACDF). Methods: We reviewed 40 adult patients who received a stand-alone cage for elective ACDF and matched them with 40 patients who received an anterior cervical plate. We statistically compared operative time, length of stay, proportion of ambulatory cases, overall complications necessitating a trip to the ED, readmission, or reoperation related to index procedure. Results: There were 21 women and 19 men in the plate cohort with average ages of 53 years ± 12 and 20 women and 20 men in the stand-alone group with an average age of 52 years ± 11. With no statistical difference in total number, the plate group experienced 4 short-term (within 90 days of discharge) complications, including 3 patients who visited the emergency department for dysphagia and 1 who visited the emergency department for severe back pain, while the stand-alone group experienced 0 complications. There was no significant difference in operative time between the stand-alone group (75.35 min) and the plate group (81.35 min; P = .37). There was a significant difference between the proportion of ambulatory cases in the stand-alone group (25) and the plate group (6; P < .0001). Conclusion: Our results demonstrate that stand-alone cages have fewer complications compared to anterior plating, with a lower trend of incidence of postoperative dysphagia. Stand-alone cages may offer the advantage of sending patients home ambulatory after ACDF surgery. PMID:28811982

Timely detection of Acute Intra-cranial Hemorrhage (AIH) in an emergency environment is essential for the triage of patients suffering from Traumatic Brain Injury. Moreover, the small size of lesions and lack of experience on the reader's part could lead to difficulties in the detection of AIH. A CT based CAD algorithm for the detection of AIH has been developed in order to improve upon the current standard of identification and treatment of AIH. A retrospective analysis of the algorithm has already been carried out with 135 AIH CT studies with 135 matched normal head CT studies from the Los Angeles County General Hospital/ University of Southern California Hospital System (LAC/USC). In the next step, AIH studies have been collected from Walter Reed Army Medical Center, and are currently being processed using the AIH CAD system as part of implementing a multi-site assessment and evaluation of the performance of the algorithm. The sensitivity and specificity numbers from the Walter Reed study will be compared with the numbers from the LAC/USC study to determine if there are differences in the presentation and detection due to the difference in the nature of trauma between the two sites. Simultaneously, a stand-alone system with a user friendly GUI has been developed to facilitate implementation in a clinical setting.

Life cycle cost analysis of a stand-alone PV system in rural Kenya

NASA Astrophysics Data System (ADS)

Daly, Emma

The purpose of this quantitative research study was to determine the economic feasibility of a stand-alone PV system to electrify a rural area in Kenya. The research conducted involved a comprehensive review of all the relevant literature associated with the study. Methodologies were extrapolated from this extensive literature to develop a model for the complete design and economic analysis of a stand-alone PV system. A women's center in rural Kenya was used as a worked example to demonstrate the workings of the model. The results suggest that electrifying the center using a stand-alone PV system is an economically viable option which is encouraging for the surrounding area. This model can be used as a business model to determine the economic feasibility of a stand-alone PV system in alternative sites in Kenya.

From a social ecological perspective, this study examined the effects of stigma (societal level), trusting relationships with current caregivers (familial level), and self-esteem (individual level) on future orientation of children affected by HIV infection and AIDS. Comparing self-report data from 1221 children affected by parental HIV infection and AIDS and 404 unaffected children, affected children reported greater stigma and lower future orientation, trusting relationships, and self-esteem. Based on structural equation modeling, stigma experiences, trusting relationships, and self-esteem had direct effects on future orientation, with self-esteem and trusting relationships partially mediating the effect of stigma experiences on children's future orientation. Implications are discussed. © The Author(s) 2014.

The value of support for aid workers in complex emergencies: a phenomenological study.

PubMed

Hearns, Annette; Deeny, Pat

2007-01-01

More disasters worldwide are now classified as complex emergencies, thereby increasing the threat to life and limb and potentially increasing the psychosocial impact of the experience for aid workers. This study examines the concept of support as perceived by aid workers who had recent experience in complex emergencies. Using a phenomenological approach, 6 professional aid workers were interviewed about their experience. Aid workers who work in complex emergencies do not feel supported at the pre-deployment, during deployment, and after deployment phases. Failure to provide this support may cause disappointment, reduced self-worth, anger with the organization, and feeling of lack of achievement regarding self and the mission. While the study may be limited by the volunteer sample and potential bias in data collection, the findings reiterate a proverbial but important issue in relation to aid relief staff in complex emergencies.

To provide culturally appropriate HIV/AIDS patient care, it is important to develop symptom management patient education materials for patients with different cultural backgrounds. The purpose of this study was to develop a Spanish version of the Symptom Management Guidebook: Strategies for People Living with HIV/AIDS guidelines and verify its content, perceived feasibility, and usefulness with HIV/AIDS care providers and people living with HIV/AIDS in Puerto Rico. The Symptom Management Guidebook includes self-care strategies to manage 14 common HIV-related symptoms. The Spanish version was developed by adopting and translating through forward and backward translation methods. Seven HIV/AID Shealth care providers from San Juan, Puerto Rico, were invited to review and revise the contents. Ten people living with HIV/AIDS from a community AIDS clinic in San Juan participated in a focus group to review the guidebook and discussed its usefulness and feasibility for managing their symptoms. Participants expressed positive responses and considered an educational guidebook as a helpful tool for self-managing their symptoms. Results suggested that this guidebook may be useful as an intervention strategy for symptom management in HIV/AIDS patients. Future research can include testing self-managing intervention and its outcomes in culturally diverse HIV/AIDS patients.

Background and Objectives: Addicts account for approximately 68.15% of AIDS cases in Iran and injection drug users are considered as a major factor in the spread of AIDS in Iran. The purpose of this study was to determine the effect of an educational intervention on the perceived self-efficacy, benefits, and barriers concerning AIDS preventive behaviors among drug addicts in Khorramabad, Iran. Methods: This is a quasi-experimental study carried out in 2013 on 88 addicts kept in rehabilitations center in Khorramabad. The data collection instruments included a questionnaire on self-efficacy, perceived benefits, perceived barriers, knowledge and preventive behaviors regarding HIV. Data were analyzed by paired t-test, independent t-test, Chi-square and analysis of covariance. Results: Paired t-test showed that the mean scores for perceived benefits and barriers, knowledge and preventive behaviors significantly increased in the intervention group after the intervention than before the intervention. But the increase in self-efficacy score was not statistically significant. Conclusions: The results of this study showed that training and education based on the health belief model led to an increase in knowledge, self-efficacy, perceived benefits, performance and reduction in perceived barriers in addicts. It is recommended that future studies should include strategies for enhancing self-efficacy and perceived benefits as well as strategies for reducing barriers to the adoption of preventive behaviors.

2010-01-01

This study evaluated an economic empowerment intervention designed to promote life options, health and mental health functioning among AIDS-orphaned adolescents in rural Uganda. The study used an experimental design in which adolescents (N=267) were randomly assigned to receive an economic empowerment intervention or usual care for orphaned children. The study measured mental health functioning using 20 items of the Tennessee Self-Concept Scale (TSCS: 2)—a standardized measure for self-esteem—and measured overall health using a self-rated health measure. Data obtained at 10-month follow-up revealed significant positive effects of the economic empowerment intervention on adolescents’ self-rated health and mental health functioning. Additionally, health and mental health functioning were found to be positively associated with each other. The findings have implications for public policy and health programming for AIDS-orphaned adolescents. PMID:19520472

2015-01-01

Introduction Presbycusis is a consequence of aging. Prescription of hearing aids is part of the treatment, although the prevalence of use by elderly people is still small. Objective To verify whether or not self-assessment of hearing is a predictor for purchase of hearing aids. Methods Quantitative, cross-sectional, descriptive, and observational study. Participants were subjects who sought a private hearing center for selection of hearing aids. During the diagnostic interview, subjects answered the following question: “On a scale of 1 to 10, with 1 being the worst and 10 the best, how would you rate your overall hearing ability?” After that, subjects underwent audiometry, selected a hearing aid, performed a home trial, and decided whether or not to purchase the hearing aid. The variables were associated and analyzed statistically. Results The sample was comprised of 32 subjects, both men and women, with a higher number of women. Mean age was 71.41 ± 12.14 years. Self-assessment of hearing ranged from 2 to 9 points. Overall, 71.9% of the subjects purchased hearing aids. There was no association between scores in the self-assessment and the purchase of hearing aids (p = 0.263). Among those who scored between 2 and 5 points, 64.7% purchased the device; between 6 and 7 points, 76.09% purchased the device; and between 8 and 9 points, 50% purchased the device, respectively. Conclusion There is evidence that low self-assessment scores lead to the purchase of hearing aids, although no significant association was observed in the sample. PMID:26722346

WE-E-217A-02: Methodologies for Evaluation of Standalone CAD System Performance.

PubMed

Sahiner, B

2012-06-01

Standalone performance evaluation of a CAD system provides information about the abnormality detection or classification performance of the computerized system alone. Although the performance of the reader with CAD is the final step in CAD system assessment, standalone performance evaluation is an important component for several reasons: First, standalone evaluation informs the reader about the performance level of the CAD system and may have an impact on how the reader uses the system. Second, it provides essential information to the system designer for algorithm optimization during system development. Third, standalone evaluation can provide a detailed description of algorithm performance (e.g., on subgroups of the population) because a larger data set with more samples from different subgroups can be included in standalone studies compared to reader studies. Proper standalone evaluation of a CAD system involves a number of key components, some of which are shared with the assessment of reader performance with CAD. These include (1) selection of a test data set that allows performance assessment with little or no bias and acceptable uncertainty; (2) a reference standard that indicates disease status as well as the location and extent of disease; (3) a clearly defined method for labeling each CAD mark as a true-positive or false-positive; and (4) a properly selected set of metrics to summarize the accuracy of the computer marks and their corresponding scores. In this lecture, we will discuss various approaches for the key components of standalone CAD performance evaluation listed above, and present some of the recommendations and opinions from the AAPM CAD subcommittee on these issues. Learning Objectives 1. Identify basic components and metrics in the assessment of standalone CAD systems 2. Understand how each component may affect the assessed performance 3. Learn about AAPM CAD subcommittee's opinions and recommendations on factors and metrics related to the evaluation of standalone CAD system performance. © 2012 American Association of Physicists in Medicine.

2013-01-01

Hearing loss is a major handicap in developing countries with paucity of trained audiologists and limited resources. In this pilot study trained community health workers were used to provide comprehensive hearing aid services in the community. One hundred and eleven patients were fitted with semi-digital hearing aid and were evaluated over a period of six months. They were assessed using self-report outcome measure APHAB. Results show that trained CHWs are effective in detecting disabling hearing loss and in providing HAs. APHAB can identify and pick up significant improvements in communication in daily activities and provides a realistic expectation of the benefits of a hearing aid. The model of using trained CHWs to provide rehabilitative services in audiology along with self-report outcome measures can be replicated in other developing countries. PMID:23724277

Background: In spite of developed countries there are progressive trend about HIV/AIDS and its’ aspects of transmission in the low socio-economic societies. The aim of this was to explain the youth's behavior in adopting HIV/AIDS related preventive behaviors in a sample of Iranian university students by emphasizing on fear appeals approaches alongside examining the role of self-control trait for explaining adoption on danger or fear control processes based on Extended Parallel Process Model (EPPM). Methods: A sample of 156 randomly selected university students in Jolfa, Iran was recruited in a predictive cross-sectional study by application of a researcher-designed questionnaire through self-report data collection manner. Sexual high risk behaviors, the EPPM variables, self-control trait, and general self-efficacy were measured as theoretical framework. Results: Findings indicated that 31.3% of participants were in the fear control process versus 68.7% in danger control about HIV/AIDS and also the presence of multi-sex partners and amphetamine consumption amongst the participants. Low self-control trait and low perceived susceptibility significantly were related to having a history of multi-sex partners while high level of self-efficacy significantly increased the probability of condom use. Conclusion: Findings of the study were indicative of the protective role of high level of self-control, perceived susceptibility and self-efficacy factors on youth's high-risk behaviors and their preventative skills as well.

2015-01-01

How to identify whether students are satisfied with clickers-aided EFL class might be largely a mystery for most researchers since satisfaction is deeply hidden in human psychology which is subtle and intangible. This study, by using bivariate correlation analysis and structural equation modeling, survey scales claimed both valid and internally consistent, and data collected from randomly selected 227 participants, explored the indicators of satisfaction in clickers-aided EFL class, together with gender differences in the indicators. It was concluded that satisfaction was positively correlated with interaction, self-efficacy and self-regulation in clickers-aided EFL class without statistically significant gender differences. Furthermore, interaction, self-efficacy and self-regulation were mutually and significantly correlated. Although indicators of satisfaction might not be limited to these three factors, the findings should be helpful to future researchers who desire to determine whether users are satisfied with the polling technology. Then teachers could decide what teaching style and contents should be adopted. In order to satisfy users of clickers, future lecturing might be designed to promote peer interaction, self-efficacy and self-regulation.

Ramer, Lois; Johnson, Debra; Chan, Linda; Barrett, Mary Theresa

2006-07-01

This study examined the relationship of sociodemographic and clinical factors with spirituality and self-transcendence in people with HIV/AIDS. It involved 420 HIV/AIDS patients from an HIV clinic who were predominantly Hispanic (79%) and male (82%), with a mean age of 39 years. Subjects completed spirituality, self-transcendence, health status, and depression scales. Medical charts were reviewed to obtain demographics, current therapies, depression diagnosis, CD4 cells (sometimes called T-cells), and viral load levels. Self-transcendence was related to levels of energy (p < .05) and acculturation (p < .05). Spirituality was related to levels of energy (p < .001) and pain (p < .02). Neither disease progression nor severity was related to self-transcendence or spirituality. The findings suggest the concept of self-transcendence may not be culturally meaningful to Hispanic patients. The development of valid and reliable tools specific for this population is important for future research.

Vedel, Ellen; Emmelkamp, Paul M G; Schippers, Gerard M

2008-01-01

Alcohol abuse serves as a chronic stressor between partners and has a deleterious effect on relationship functioning. Behavioral Couples Therapy (BCT) for alcohol dependence, studied as an adjunct to individual outpatient counseling, has shown to be effective in decreasing alcohol consumption and enhancing marital functioning, but no study has directly tested the comparative effectiveness of stand-alone BCT versus an individually focused cognitive-behavioral therapy (CBT) in a clinical community sample. The present study is a randomized clinical trial evaluating the effectiveness of stand-alone BCT (n = 30) compared to individual CBT (n = 34) in the treatment of alcohol use disorders in community treatment centers in Dutch male and female alcoholics and their partners. Results show both BCT and CBT to be effective in changing drinking behavior after treatment. BCT was not found to be superior to CBT. Marital satisfaction of the spouse increased significantly in the BCT condition but not in the CBT condition, the differences being significant at the post-test. Patients' self-efficacy to withstand alcohol-related high-risk situations increased significantly in both treatment conditions, but more so in CBT than in BCT after treatment. Treatment involvement of the spouse did not increase retention. Regular practitioners in community treatment centers can effectively deliver both treatments. Stand-alone BCT is as effective as CBT in terms of reduced drinking and to some extent more effective in terms of enhancing relationship satisfaction. However, BCT is a more costly intervention, given that treatment sessions lasted almost twice as long as individual CBT sessions. Copyright 2008 S. Karger AG, Basel.

To examine the impact of self-efficacy and expectations for hearing aids, and readiness to improve hearing, on hearing aid outcome measures in first-time adult hearing aid users Design: A prospective, single centre design. Predictor variables measured at the hearing assessment included measures of self-efficacy, expectations and readiness to improve hearing. Outcome measures obtained at six-week follow-up were the Glasgow Hearing Aid Benefit Profile and Satisfaction with Amplification in Daily Life. A sample of 30 first-time adult hearing aid users were recruited through a public-sector funded audiology clinic. When measured prior to hearing aid fitting, self-efficacy for hearing aids predicted satisfaction with hearing aids but was not related to other hearing aid outcomes. Expectations of hearing aids, in particular positive expectations, and readiness to improve hearing predicted outcomes for hearing aid satisfaction and benefit, although not hearing aid use. Hearing sensitivity was not correlated with hearing aid outcomes. These results suggest that assessment of expectations of hearing aids, and readiness to improve hearing, may be useful to help identify individuals attending audiology clinics who would most likely benefit from hearing aid provision.

A RLS-SVM Aided Fusion Methodology for INS during GPS Outages

PubMed Central

Yao, Yiqing; Xu, Xiaosu

2017-01-01

In order to maintain a relatively high accuracy of navigation performance during global positioning system (GPS) outages, a novel robust least squares support vector machine (LS-SVM)-aided fusion methodology is explored to provide the pseudo-GPS position information for the inertial navigation system (INS). The relationship between the yaw, specific force, velocity, and the position increment is modeled. Rather than share the same weight in the traditional LS-SVM, the proposed algorithm allocates various weights for different data, which makes the system immune to the outliers. Field test data was collected to evaluate the proposed algorithm. The comparison results indicate that the proposed algorithm can effectively provide position corrections for standalone INS during the 300 s GPS outage, which outperforms the traditional LS-SVM method. Historical information is also involved to better represent the vehicle dynamics. PMID:28245549

Bogale, Gebeyehu W; Boer, Henk; Seydel, Erwin R

2011-02-01

In Ethiopia the level of illiteracy in rural areas is very high. In this study, we investigated the effects of an audio HIV/AIDS prevention intervention targeted at rural illiterate females. In the intervention we used social-oriented presentation formats, such as discussion between similar females and role-play. In a pretest and posttest experimental study with an intervention group (n = 210) and control group (n = 210), we investigated the effects on HIV/AIDS knowledge and social cognitions. The intervention led to significant and relevant increases in HIV/AIDS knowledge, self-efficacy, perceived vulnerability to HIV/AIDS infection, response efficacy of condoms and condom use intention. In the intervention group, self-efficacy at posttest was the main determinant of condom use intention, with also a significant contribution of vulnerability. We conclude that audio HIV/AIDS prevention interventions can play an important role in empowering rural illiterate females in the prevention of HIV/AIDS.

2014-01-01

Human-in-the-loop testing was completed to assess the subjective preferences, usage, and operational benefits of Integrated and Separated Controller Information Tools (CITs) in support of Generic Airspace Research. Participants controlled traffic in in a busy, high altitude sector with the aid of the CITs. When the participants were asked which CIT that they preferred to use, they overwhelmingly chose the integrated version of the CIT. The primary reason for this seemed to be that it allowed participants to remain focused on the traffic situation, whereas the Standalone CIT required them to focus their attention for short periods away from the radar presentation. In contrast to their preference, there were little or no differences in the CIT usage and the operational differences. There were similar numbers of losses of separation and participants accessed each CIT equally. Although the information accessed was the similar for the two conditions, participants actively turned off the data on the Integrated CIT, presumably to reduce the clutter on the radar scope. Further work is needed to isolate which information can and should be available to controllers in the Integrated vs. Standalone format.

2016-05-01

The aim of this study was to define the extent to which leadership and leadership skills are taught in dental hygiene degree completion programs by comparing stand-alone leadership courses/hybrid programs with programs that infuse leadership skills throughout the curricula. The study involved a mixed-methods approach using qualitative and quantitative data. Semi-structured interviews were conducted with program directors and faculty members who teach a stand-alone leadership course, a hybrid program, or leadership-infused courses in these programs. A quantitative comparison of course syllabi determined differences in the extent of leadership content and experiences between stand-alone leadership courses and leadership-infused curricula. Of the 53 U.S. dental hygiene programs that offer degree completion programs, 49 met the inclusion criteria, and 19 programs provided course syllabi. Of the program directors and faculty members who teach a stand-alone leadership course or leadership-infused curriculum, 16 participated in the interview portion of the study. The results suggested that competencies related to leadership were not clearly defined or measurable in current teaching. Reported barriers to incorporating a stand-alone leadership course included overcrowded curricula, limited qualified faculty, and lack of resources. The findings of this study provide a synopsis of leadership content and gaps in leadership education for degree completion programs. Suggested changes included defining a need for leadership competencies and providing additional resources to educators such as courses provided by the American Dental Education Association and the American Dental Hygienists' Association.

Paradoxes and Prospects: Moving beyond the Study of Foreign Aid

Mundy, Karen

2010-01-01

In his article, "Aid, Development, and Education," Steve Klees tells two stories about foreign aid. The first is that foreign aid does not "work" to alleviate world poverty, no matter whether one takes a neo-Marxist or liberal approach to understanding it. Aid is more about self-interest and geopolitics than anything else--at best it is a form of…

For 20 years, China has participated in 267 international cooperation projects against the HIV/AIDS epidemic and received ∼526 million USD from over 40 international organizations. These projects have played an important role by complementing national efforts in the fight against HIV/AIDS in China. The diverse characteristics of these projects followed three phases over 20 years. Initially, stand-alone projects provided technical support in surveillance, training or advocacy for public awareness. As the epidemic spread across China, projects became a part of the comprehensive and integrated national response. Currently, international best practices encourage the inclusion of civil society and non-governmental organizations in an expanded response to the epidemic. Funding from international projects has accounted for one-third of the resources provided for the HIV/AIDS response in China. Beyond this strong financial support, these programmes have introduced best practices, accelerated the introduction of AIDS policies, strengthened capacity, improved the development of grassroots social organizations and established a platform for communication and experience sharing with the international community. However, there are still challenges ahead, including integrating existing resources and exploring new programme models. The National Centre for AIDS/STD Control and Prevention (NCAIDS) in China is consolidating all international projects into national HIV prevention, treatment and care activities. International cooperation projects have been an invaluable component of China's response to HIV/AIDS, and China has now been able to take this information and share its experiences with other countries with the help of these same international programmes.

iDrug: a web-accessible and interactive drug discovery and design platform

PubMed Central

2014-01-01

Background The progress in computer-aided drug design (CADD) approaches over the past decades accelerated the early-stage pharmaceutical research. Many powerful standalone tools for CADD have been developed in academia. As programs are developed by various research groups, a consistent user-friendly online graphical working environment, combining computational techniques such as pharmacophore mapping, similarity calculation, scoring, and target identification is needed. Results We presented a versatile, user-friendly, and efficient online tool for computer-aided drug design based on pharmacophore and 3D molecular similarity searching. The web interface enables binding sites detection, virtual screening hits identification, and drug targets prediction in an interactive manner through a seamless interface to all adapted packages (e.g., Cavity, PocketV.2, PharmMapper, SHAFTS). Several commercially available compound databases for hit identification and a well-annotated pharmacophore database for drug targets prediction were integrated in iDrug as well. The web interface provides tools for real-time molecular building/editing, converting, displaying, and analyzing. All the customized configurations of the functional modules can be accessed through featured session files provided, which can be saved to the local disk and uploaded to resume or update the history work. Conclusions iDrug is easy to use, and provides a novel, fast and reliable tool for conducting drug design experiments. By using iDrug, various molecular design processing tasks can be submitted and visualized simply in one browser without installing locally any standalone modeling softwares. iDrug is accessible free of charge at http://lilab.ecust.edu.cn/idrug.

The lived experience of self-transcendence in gay men with AIDS.

PubMed

Coward, D D; Lewis, F M

1993-10-01

This phenomenologic study described the structure of self-transcendence in eight gay men with AIDS. The men provided oral or written descriptions of experiences associated with feelings of increased interconnectedness with others, sense of well-being, and meaning and purpose in life. The data were analyzed using Colaizzi's phenomenologic technique. The men experienced self-transcendence in the three ways described by Frankl. Reaching out for help and helping others alleviated the men's sense of aloneness and isolation. Their acceptance of the closeness of death led to a sense of urgency to create a legacy and to participate only in activities that had meaning for them. Knowledge of these views and behaviors may help nurses to create a therapeutic exchange in which self-transcendent views are fostered in other gay men with AIDS.

Prevalence and factors associated with HIV/AIDS-related stigma and discriminatory attitudes: a cross-sectional nationwide study.

PubMed

Wong, Li Ping

2013-01-01

The prime purpose of this study is to assess HIV/AIDS-related self-stigma and discrimination (S&D) attitudes and associated factors using multivariate analysis of data from the 2010-11 National Survey of Understanding the Root of HIV/AIDS Related Stigma and Discrimination. A national telephone survey was carried out with 2271 of the Malaysian public aged 18-60 years. The sample was contacted by random digit dialing covering the whole of Peninsular Malaysia from December 2010 to May 2011. The HIV-transmission knowledge, HIV-related self-stigma, and public stigma were investigated. Despite high level of HIV-transmission knowledge [mean (SD)=10.56 (2.42), mean score at 70th percentile] the respondents in this study had moderate levels (mean scores near midpoints) of self-stigma and public stigma attitudes. HIV-transmission knowledge score was not significantly correlated with self-stigma score, but showed a significantly small positive effect (r<0.2) for public stigma scores. Ethnicity is the strongest correlate of HIV-transmission knowledge, self-stigma, and public stigma attitudes in the multivariate analyses. Other significant correlates were age, socioeconomic group, and urban-rural setting. The root causes of HIV stigma and discriminatory attitudes were not associated with knowledge deficiency. Interventions should be oriented towards promoting de-stigmatization of HIV/AIDS, and tailored socio-culturally. Copyright © 2013 Elsevier Inc. All rights reserved.

How to Implement Therapeutic Evaluative Conditioning in a Clinical Setting.

PubMed

Franklin, Joseph C; Fox, Kathryn R; Ribeiro, Jessica D

2017-05-01

Self-injurious behaviors (SIBs), including both suicidal and nonsuicidal self-injury, are major public health problems that have been on the rise in recent decades. There are few effective SIB interventions, and those that are effective cannot reach most people who are in need of help-that is, these interventions are not scalable. To address this need, we recently developed a scalable, app-based treatment called Therapeutic Evaluative Conditioning (TEC) that preliminary studies have shown causes reductions in SIBs (Franklin et al., 2016). Although TEC was developed and evaluated as a standalone, self-administered intervention, it may also be a valuable therapeutic tool within traditional clinical settings. Here we provide a case illustration of a young adult female who presented at an outpatient clinic with a long history of self-injurious behaviors and multiple failed treatment attempts. In discussing this case, we describe how to implement TEC within such a setting and what might be expected as a result. © 2017 Wiley Periodicals, Inc.

The influence of highly automated driving on the self-perception of drivers in the context of Conduct-by-Wire.

PubMed

Kauer, Michaela; Franz, Benjamin; Maier, Alexander; Bruder, Ralph

2015-01-01

Today, new driving paradigms are being introduced that aim to reduce the number of standalone driver assistance systems by combining these into one overarching system. This is done to reduce the demands on drivers but often leads to a higher degree of automation. Feasibility and driver behaviour are often the subject of studies, but this is contrasted by a lack of research into the influence of highly automated driving on the self-perception of drivers. This article begins to close this gap by investigating the influences of one highly automated driving concept--Conduct-by-Wire--on the self-perception of drivers via a combined driving simulator and interview study. The aim of this work is to identify changes in the role concept of drivers indicated by highly automated driving, to evaluate these changes from the drivers' point of view and to give suggestions of possible improvements to the design of highly automated vehicles.

A Self-Excited Induction Generation (SEIG) for a variable speed wind turbine generation(VS-WG) is normally considered to be a good candidate for implementation in stand-alone applications such as battery charging, hydrogenation, water pumping, water purification, water desalination, and etc. In this study, we have examined a study on active power and flux control strategies for a SEIG for a variable speed wind turbine generation. The control analysis for the proposed system is carried out by using PSCAD software. In the process, we can optimize the control design of the system, thereby enhancing and expediting the control design procedure for this application.more » With this study, this control design for a SEIG for VS-WG can become the industry standard for analysis and development in terms of SEIG.« less

Meaning and purpose in the lives of persons with AIDS.

PubMed

Coward, D D

1994-10-01

Little research has been reported that explores meaning-discovery and meaning-making in persons with AIDS. Self-transcendence experiences, as proposed by Reed (1991), may lead to maintenance or restoration of mental health in persons facing end-of-life issues. Nurses who work with persons with life-threatening illness, such as men and women with AIDS, have opportunities to facilitate choices that lead to experiences from which meaning and emotional well-being may be obtained. This study used a phenomenological approach to describe experiences of 10 men and 10 women with AIDS that led to feelings of increased self-worth, purpose, and meaning in their lives. Participants provided oral or written descriptions of experiences associated with feelings of increased connectedness with others, sense of well-being, and hope for longer life. Data were analyzed using Colaizzi's phenomenological technique (1978). Although men and women with AIDS faced some of the same issues, their responses were different. By incorporating gender and individual differences, nurses may be better able to create therapeutic exchanges in which self-transcendence views and behaviors are fostered in both men and women with AIDS.

A program of symptom management for improving self-care for patients with HIV/AIDS.

2004-09-01

The purpose of this study was to investigate the effect of a symptom management program on self-care of medication side effects among AIDS/HIV-positive patients. Sixty-seven patients from a sexually transmitted disease control center, a medical center, and a Catholic AIDS support group in Taipei were randomly assigned to three groups: one-on-one teaching, group teaching, and a control group. All subjects in each teaching group attended a 60- or 90-minute program on highly active antiretroviral therapy (HAART) side effect self-care education and skill training once per week for 3 weeks; subjects also underwent counseling by telephone. A medication side effect self-care knowledge questionnaire, Rosenberg's Self-Esteem Scale (RSES), and unscheduled hospital visits were used to evaluate the effectiveness of the symptom management program. The results revealed there were significant differences in mean difference of knowledge and unscheduled hospital visits between baseline and post-testing at 3 months for symptom management in the two groups. The mean difference of the self-esteem scale was not significant between the two groups. In summary, the symptom management program effectively increased the ability of AIDS/HIV-positive patients to self-care for medication side effects. We recommend that this program be applied in the clinical nursing practice.

Parental illness and death due to human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) impose challenges to children's psychological adjustment. Positive psychology emphasizes individual's resilience in the face of adversity, trauma, and tragedy. Limited data are available regarding the factors that can cultivate resilience of children affected by HIV/AIDS. This study aims to examine the role of extracurricular interest in strengthening resilience among children affected by HIV/AIDS. Participants included 755 children orphaned by parental HIV/AIDS, 466 vulnerable children living with HIV-positive parent(s), and 404 comparison children from HIV-free families in the same community in rural China. The measures include extracurricular interest (i.e., reading, sports, music, painting, science, and playing chess) and indicators of psychological adjustment (i.e., depression, loneliness, and self-esteem). Having extracurricular interest was positively associated with self-esteem and negatively associated with depression and loneliness. Having extracurricular interest attenuated the negative effect of parental HIV/AIDS on children's self-esteem and loneliness, after controlling for children's age, gender, and family socioeconomic status. The findings underscore the importance of nurturing extracurricular interest and make available of such activities to promote resilience for children affected by HIV/AIDS in resource-limited settings.

Que(e)rying the clinic before AIDS: practicing self-help and transversality in the 1970s.

PubMed

Diedrich, Lisa

2013-06-01

In this paper, I offer a treatment of "the clinic" in which the clinic-as concept and space-is que(e)ried, that is, both questioned and made queer. I present two historical case studies that queer clinical thought and practices in the period before AIDS and before the full-blown arrival of queer theory on the western theoretical landscape. These two cases-the practice of self-help developed in the women's health movement in the United States and the practice of tranversality developed out of and beyond the Institutional Psychiatry movement in France-challenge the practice of medicine in the prehistory of both AIDS and queer theory, yet, they are not generally seen as precursors, or related in any way, to AIDS activism. In a sense, then, I also want to question and make queer the history of AIDS as we conventionally know it today by extending that history backwards and outwards to earlier queer critical and clinical practices like self-help and transversality.

Assistive hearing technologies among students with hearing impairment: factors that promote satisfaction.

PubMed

Rekkedal, Ann Mette

2012-01-01

Hearing technology can play an essential part in the education of deaf and hard-of-hearing children in inclusive schools. Few studies have examined these children's experiences with this technology. This article explores factors pertaining to children's use of and attitudes toward hearing technologies, such as hearing aids, cochlear implants, teacher-worn microphones, and student-worn microphones. The study included 153 deaf and hard-of-hearing students. All students communicated orally and were in inclusive schools from grades 5-10. The results suggest that males view hearing technology more positively than do females. Having severe hearing loss also promoted positive attitudes toward hearing aids and cochlear implants, but not toward microphones. The students with positive self-descriptions tended to be more satisfied with hearing aids or cochlear implants than the students with negative self-descriptions. The main factors promoting the use of hearing aids were severe hearing loss, positive attitudes toward hearing aids, and the sound quality of hearing aids.

Ridgway, Jason; Hickson, Louise; Lind, Christopher

2016-07-01

To explore the explanatory power of a self-determination theory (SDT) model of health behaviour change for hearing aid adoption decisions and fitting outcomes. A quantitative approach was taken for this longitudinal cohort study. Participants completed questionnaires adapted from SDT that measured autonomous motivation, autonomy support, and perceived competence for hearing aids. Hearing aid fitting outcomes were obtained with the international outcomes inventory for hearing aids (IOI-HA). Sociodemographic and audiometric information was collected. Participants were 216 adult first-time hearing help-seekers (125 hearing aid adopters, 91 non-adopters). Regression models assessed the impact of autonomous motivation and autonomy support on hearing aid adoption and hearing aid fitting outcomes. Sociodemographic and audiometric factors were also taken into account. Autonomous motivation, but not autonomy support, was associated with increased hearing aid adoption. Autonomy support was associated with increased perceived competence for hearing aids, reduced activity limitation and increased hearing aid satisfaction. Autonomous motivation was positively associated with hearing aid satisfaction. The SDT model is potentially useful in understanding how hearing aid adoption decisions are made, and how hearing health behaviour is internalized and maintained over time. Autonomy supportive practitioners may improve outcomes by helping hearing aid adopters maintain internalized change.

This pilot study tests the feasibility of using a Talking Circle approach and measures cultural values and beliefs within a HIV/AIDS and hepatitis C virus (HCV) prevention program conducted among a Native American (Cherokee) youth population. A descriptive correlation design was used to examine the relationship between Cherokee self-reliance and HIV/AIDS and HCV knowledge, attitudes, and behaviors. The study used three questionnaires that were administered before and after the prevention program to collect data from a convenience sample of 41 students at a public high school within the boundaries of the Cherokee Nation in Oklahoma. Statistical analysis revealed immediate differences between pretests and posttests related to knowledge, attitudes, and behavioral intentions concerning HIV/AIDS and HCV and the cultural dynamic of Cherokee self-reliance.

Aid is a key regulator of myeloid/erythroid differentiation and DNA methylation in hematopoietic stem/progenitor cells

Recent studies have reported that activation-induced cytidine deaminase (AID) and ten-eleven-translocation (TET) family members regulate active DNA demethylation. Genetic alterations of TET2 occur in myeloid malignancies, and hematopoietic-specific loss of Tet2 induces aberrant hematopoietic stem cell (HSC) self-renewal/differentiation, implicating TET2 as a master regulator of normal and malignant hematopoiesis. Despite the functional link between AID and TET in epigenetic gene regulation, the role of AID loss in hematopoiesis and myeloid transformation remains to be investigated. Here, we show that Aid loss in mice leads to expansion of myeloid cells and reduced erythroid progenitors resulting in anemia, with dysregulated expression of Cebpa and Gata1, myeloid/erythroid lineage-specific transcription factors. Consistent with data in the murine context, silencing of AID in human bone marrow cells skews differentiation toward myelomonocytic lineage. However, in contrast to Tet2 loss, Aid loss does not contribute to enhanced HSC self-renewal or cooperate with Flt3-ITD to induce myeloid transformation. Genome-wide transcription and differential methylation analysis uncover the critical role of Aid as a key epigenetic regulator. These results indicate that AID and TET2 share common effects on myeloid and erythroid lineage differentiation, however, their role is nonredundant in regulating HSC self-renewal and in myeloid transformation.

2011-10-01

To investigate word recognition in noise in subjects treated in childhood with chemotherapy, study benefits of open-fitting hearing-aids for word recognition, and investigate whether self-reported hearing-handicap corresponded to subjects' word recognition ability. Subjects diagnosed with cancer and treated with platinum-based chemotherapy in childhood underwent audiometric evaluations. Fifteen subjects (eight females and seven males) fulfilled the criteria set for the study, and four of those received customized open-fitting hearing-aids. Subjects with cisplatin-induced ototoxicity had severe difficulties recognizing words in noise, and scored as low as 54% below reference scores standardized for age and degree of hearing loss. Hearing-impaired subjects' self-reported hearing-handicap correlated significantly with word recognition in a quiet environment but not in noise. Word recognition in noise improved markedly (up to 46%) with hearing-aids, and the self-reported hearing-handicap and disability score were reduced by more than 50%. This study demonstrates the importance of testing word recognition in noise in subjects treated with platinum-based chemotherapy in childhood, and to use specific custom-made questionnaires to evaluate the experienced hearing-handicap. Open-fitting hearing-aids are a good alternative for subjects suffering from poor word recognition in noise.

Cranial electrotherapy stimulation for treatment of anxiety, depression, and insomnia.

Cranial electrotherapy stimulation is a prescriptive medical device that delivers a mild form of electrical stimulation to the brain for the treatment of anxiety, depression, and insomnia. It is supported by more than 40 years of research demonstrating its effectiveness in several mechanistic studies and greater than 100 clinical studies. Adverse effects are rare (<1%), mild, and self-limiting, consisting mainly of skin irritation under the electrodes and headaches. Often used as a stand-alone therapy, because results are usually seen from the first treatment, cranial electrotherapy stimulation may also be used as an adjunctive therapy.

2006-01-01

This research aimed at systematizing nursing care to HIV/aids patients in view of Orem's Self-care Deficit Nursing Theory, using the convergent-care method and the Self-Care Nursing Process. Subjects were thirteen HIV/AIDS patients attended at a non-governmental organization in Fortaleza/CE, Brazil. We used interview techniques, physical examination, observation and information records, with a structured instrument, addressing requisites related to universal self-care, development and health alterations. Self-care deficits corresponded to nineteen nursing diagnoses, named according to NANDA's Taxonomy II, ten of which were based on the requisites for universal self-care, five on the requisites for self-care related to development and four on the requisites for self-care related to health deviations. In care planning, goals were established and the system and health methods were selected, prioritizing support-education actions in order to engage HIV/aids patients in self-care.

Preliminary support for a brief psychological intervention to improve first-time hearing aid use among adults.

Armitage, Christopher J; Lees, Deborah; Lewis, Kathryn; Munro, Kevin J

2017-11-01

Suboptimal hearing aid use extorts significant social, health, and economic costs. The aims of this study were to (1) test the novel hypothesis that the threat associated with being diagnosed with hearing loss could be ameliorated with a self-affirmation manipulation and (2) gauge the feasibility of deploying the manipulation in routine clinical practice. Parallel groups randomized controlled trial with 10-week follow-up. Fifty people, newly prescribed with a hearing aid, completed either a questionnaire that included a brief self-affirming exercise or an identical questionnaire with no self-affirming exercise. The main outcome measure was derived from data logging automatically stored by the hearing aid. Perceived threat ('anxiety about ageing'), behavioural intention, and self-efficacy were measured as potential mediators. Objectively measured hours of daily hearing aid use were marginally higher in the intervention group compared with the control group (between-group difference = 1.94 hr, 95%CI = -1.24, 5.12, d = 0.43). At follow-up, participants in the intervention group were significantly less anxious about ageing and more accepting of older people than were participants in the control group (between-group difference = 0.75, 95%CI = 0.26, 1.22, d = 0.87). There was no statistically significant effect of the intervention on behavioural intention or self-efficacy. Although not statistically significant, the magnitude of the effect of the intervention on hearing aid use (d = 0.43) suggests that it would be worthwhile working towards a fully powered randomized controlled trial. The ability to reduce anxieties about ageing with this brief intervention could have far-reaching benefits for multiple patient and general population groups. Statement of contribution What is already known on this subject? Hearing impairment is more disabling than diabetes, yet hearing aid use is suboptimal. Anxieties about ageing may undermine hearing aid use. What does this study add? The study tests a brief theory-based psychological intervention to reduce anxiety about ageing and promote hearing aid use. Results show that the brief psychological intervention reduced anxiety and marginally increased objective hearing aid use. Further work is required to identify other situations in which anxieties about ageing undermine behaviour change efforts. The very brief, flexible nature of the intervention means it could be adapted and deployed in numerous other health care settings. © 2017 The Authors.

Introduction Integrating HIV with primary health services has the potential to reduce HIV-related stigma through delivering care in settings disassociated with HIV. This study investigated the relationship between integrated care and felt stigma. The study design was a comparative case study of four models of HIV care in Swaziland, ranging from fully integrated to fully stand-alone HIV care. Methods An exit survey (N=602) measured differences in felt stigma across model of care; the primary outcome “perception of HIV status exposure through clinic attendance” was analyzed using multivariable logistic regression. In-depth interviews (N=22) explored whether and how measured differences in stigma experiences were related to service integration. Results There were significant differences in perceived status exposure across models of care. After adjustment for potential confounding between sites, those at a partially integrated site and a partially stand-alone site had greater odds of perceived status exposure than those at the fully stand-alone site (aOR 3.33, 95% CI 1.98–5.60; and aOR 11.84, 95% CI 6.89–20.36, respectively). There was no difference between the fully stand-alone and the fully integrated clinic. Qualitative data suggested that many clients at HIV-only sites felt greater confidentiality knowing that those around them were positive, and support was gained from other HIV care clients. Confidentiality was maintained in various ways, even in stand-alone sites, through separate waiting areas for HIV testing and HIV treatment, and careful clinic and room labelling. Conclusions The relationship between model of care and stigma was complex, and the hypothesis that stigma is higher at stand-alone sites did not hold true in this high prevalence setting. Policy-makers should ensure that service integration does not increase stigma, in particular within partially integrated models of care. PMID:23336726

This study aims to compare the marginal accuracy of single crowns fabricated using self-curing resin, Luxatemp, and computer aided design/computer aided manufacturing (CAD/CAM) methods in clinical application. A total of 30 working dies, which were obtained from 30 clinical teeth prepared with full crown as standard, were created and made into 30 self-curing resin, Luxatemp, and CAD/CAM single crowns. The restorations were seated on the working dies, and stereomicroscope was used to observe and measure the thickness of reference points. One-way analysis of variance, which was performed using SPSS 19.0 software package, compared the marginal gap widths of self-curing resin, Luxatemp, and CAD/CAM provisional crowns. The mean marginal gap widths of the fabricated self-curing resin, Luxatemp, and CAD/CAM were (179.06±33.24), (88.83±9.56), and (43.61±7.27) μm, respectively. A significant difference was observed among the three provisional crowns (P<0.05). The marginal gap width of CAD/CAM provisional crown was lower than that of the self-curing resin and Luxatemp. Thus, the CAD/CAM provisional crown offers a better remediation effect in clinical application.

Background For 20 years, China has participated in 267 international cooperation projects against the HIV/AIDS epidemic and received ∼526 million USD from over 40 international organizations. These projects have played an important role by complementing national efforts in the fight against HIV/AIDS in China. Methods The diverse characteristics of these projects followed three phases over 20 years. Initially, stand-alone projects provided technical support in surveillance, training or advocacy for public awareness. As the epidemic spread across China, projects became a part of the comprehensive and integrated national response. Currently, international best practices encourage the inclusion of civil society and non-governmental organizations in an expanded response to the epidemic. Results Funding from international projects has accounted for one-third of the resources provided for the HIV/AIDS response in China. Beyond this strong financial support, these programmes have introduced best practices, accelerated the introduction of AIDS policies, strengthened capacity, improved the development of grassroots social organizations and established a platform for communication and experience sharing with the international community. However, there are still challenges ahead, including integrating existing resources and exploring new programme models. The National Centre for AIDS/STD Control and Prevention (NCAIDS) in China is consolidating all international projects into national HIV prevention, treatment and care activities. Conclusion International cooperation projects have been an invaluable component of China’s response to HIV/AIDS, and China has now been able to take this information and share its experiences with other countries with the help of these same international programmes.

Culture in the Courtroom: Ethnocentrism and Juror Decision-Making

PubMed Central

Maeder, Evelyn M.; Yamamoto, Susan

2015-01-01

The purpose of this study was to investigate whether a culturally-based argument in a non-insane automatism defense would be detrimental or beneficial to the defendant. We also examined how juror ethnocentrism might affect perceptions of such a defense. Participants read a fictional filicide homicide case in which the defendant claimed to have blacked out during the crime; we manipulated whether culture was used as an explanation for what precipitated the defendant’s blackout. We conducted path analyses to assess the role of ethnocentrism in predicting lower defendant credibility, and harsher verdict decisions. Results revealed an interaction between ethnocentrism and defense type, such that ethnocentrism related to lower perceived defendant credibility in the cultural condition, but not in the standard automatism condition. This study marks a starting point for empirically investigating the role of culture in the courtroom, which may aid scholars in discussing the merits of a standalone cultural defense. PMID:26353122

System Simulation by Recursive Feedback: Coupling a Set of Stand-Alone Subsystem Simulations

NASA Technical Reports Server (NTRS)

Nixon, D. D.

2001-01-01

Conventional construction of digital dynamic system simulations often involves collecting differential equations that model each subsystem, arran g them to a standard form, and obtaining their numerical gin solution as a single coupled, total-system simultaneous set. Simulation by numerical coupling of independent stand-alone subsimulations is a fundamentally different approach that is attractive because, among other things, the architecture naturally facilitates high fidelity, broad scope, and discipline independence. Recursive feedback is defined and discussed as a candidate approach to multidiscipline dynamic system simulation by numerical coupling of self-contained, single-discipline subsystem simulations. A satellite motion example containing three subsystems (orbit dynamics, attitude dynamics, and aerodynamics) has been defined and constructed using this approach. Conventional solution methods are used in the subsystem simulations. Distributed and centralized implementations of coupling have been considered. Numerical results are evaluated by direct comparison with a standard total-system, simultaneous-solution approach.

Self-efficacy for AIDS preventive behaviors among tenth grade students.

PubMed

Kasen, S; Vaughan, R D; Walter, H J

1992-01-01

To guide acquired immunodeficiency syndrome (AIDS) prevention program planning, 181 tenth grade students residing in or near an AIDS epicenter completed a survey measuring past year involvement in sexual intercourse and condom use, beliefs about self-efficacy for AIDS preventive behaviors, and beliefs about susceptibility to and severity of AIDS, and outcome efficacy of AIDS preventive actions. A degree of uncertainty existed for all areas of self-efficacy surveyed: refusing sexual intercourse under a variety of circumstances, questioning sex partners about past risky behaviors, and correct and consistent condom use. Students were most uncertain of their ability to refuse sex with a desirable partner, under pressure, or after drinking alcohol or using marijuana; to purchase condoms, or use them consistently after drinking alcohol or using marijuana; and to question partners about past homosexual history. Those students with lower self-efficacy for refusing sex were twice as likely to have had sexual intercourse. Similarly, those students with lower self-efficacy for correct, consistent condom use were five times less likely to have used condoms consistently. These associations remained even after adjusting for the influence of other AIDS-related beliefs. Implications of these findings focus on exploiting the link between self-efficacy and behavior by building a prevention program that emphasizes skills-building rather than the traditional knowledge-only approach.

An Overview of a Trajectory-Based Solution for En Route and Terminal Area Self-Spacing: Fourth Revision

NASA Technical Reports Server (NTRS)

Abbott, Terence S.

2013-01-01

This paper presents an overview of the fourth major revision to an algorithm specifically designed to support NASA's Airborne Precision Spacing concept. This airborne self-spacing concept is trajectory-based, allowing for spacing operations prior to the aircraft being on a common path. Because this algorithm is trajectory-based, it also has the inherent ability to support required-time-of-arrival (RTA) operations. This algorithm was also designed specifically to support a standalone, non-integrated implementation in the spacing aircraft. Revisions to this algorithm were based on a change to the expected operational environment.

We present a new, very efficient semi-numerical approach for the computation of state-specific nuclear gradients of a generic state-averaged multi-configuration self consistent field wavefunction. Our approach eliminates the costly coupled-perturbed multi-configuration Hartree-Fock step as well as the associated integral transformation stage. The details of the implementation within the Firefly quantum chemistry package are discussed and several sample applications are given. The new approach is routinely applicable to geometry optimization of molecular systems with 1000+ basis functions using a standalone multi-core workstation.

In workplace health promotion, all potential resources needs to be taken into consideration, not only factors relating to the absence of injury and the physical health of the workers, but also psychological aspects. A dynamic balance between the resources of the individual employees and the demands of work is an important prerequisite. In the home care services, there is a noticeable trend towards increased psychosocial strain on employees at work. There are a high frequency of work-related musculoskeletal disorders and injuries, and a low prevalence of sustainable work ability. The aim of this research was to identify factors promoting work ability and self-efficacy in care aides and assistant nurses within home care services. This study is based on cross-sectional data collected in a municipality in northern Sweden. Care aides (n = 58) and assistant nurses (n = 79) replied to a self-administered questionnaire (response rate 46%). Hierarchical multiple regression analyses were performed to assess the influence of several independent variables on self-efficacy (model 1) and work ability (model 2) for care aides and assistant nurses separately. Perceptions of personal safety, self-efficacy and musculoskeletal wellbeing contributed to work ability for assistant nurses (R2adj of 0.36, p < 0.001), while for care aides, the safety climate, seniority and age contributed to work ability (R2adj of 0.29, p = 0.001). Self-efficacy was associated with the safety climate and the physical demands of the job in both professions (R2adj of 0.24, p = 0.003 for care aides), and also by sex and age for the assistant nurses (R2adj of 0.31, p < 0.001). The intermediate factors contributed differently to work ability in the two professions. Self-efficacy, personal safety and musculoskeletal wellbeing were important for the assistant nurses, while the work ability of the care aides was associated with the safety climate, but also with the non-changeable factors age and seniority. All these factors are important to acknowledge in practice and in further research. Proactive workplace interventions need to focus on potentially modifiable factors such as self-efficacy, safety climate, physical job demands and musculoskeletal wellbeing.

Modern scientific advances have enabled remarkable efficacy for photovoltaic systems with regard to the exploitation of solar energy, boosting them into having a rapidly growing position among the systems developed for the production of renewable energy. However, in many cases the design, analysis, and control of photovoltaic systems are tasks which are quite complex and thus difficult to be carried out. In order to cope with this kind of problems, appropriate software tools have been developed either as standalone products or parts of general purpose software platforms used to model and simulate the generation, transmission, and distribution of solar energy. The utilization of this kind of software tools may be extremely helpful to the successful performance evaluation of energy systems with maximum accuracy and minimum cost in time and effort. The work presented in this paper aims on a first level at the performance analysis of various configurations of photovoltaic systems through computer-aided modelling. On a second level, it provides a comparative evaluation of the credibility of two of the most advanced graphical programming environments, namely, Simulink and LabVIEW, with regard to their application in photovoltaic systems.

2018-06-11

The objective was to determine self-adjusted output response and speech intelligibility index (SII) in individuals with mild to moderate hearing loss and to measure the effects of prior hearing aid experience. Thirteen hearing aid users and 13 nonusers, with similar group-mean pure-tone thresholds, listened to prerecorded and preprocessed sentences spoken by a man. Starting with a generic level and spectrum, participants adjusted (1) overall level, (2) high-frequency boost, and (3) low-frequency cut. Participants took a speech perception test after an initial adjustment before making a final adjustment. The three self-selected parameters, along with individual thresholds and real-ear-to-coupler differences, were used to compute output levels and SIIs for the starting and two self-adjusted conditions. The values were compared with an NAL second nonlinear threshold-based prescription (NAL-NL2) and, for the hearing aid users, performance of their existing hearing aids. All participants were able to complete the self-adjustment process. The generic starting condition provided outputs (between 2 and 8 kHz) and SIIs that were significantly below those prescribed by NAL-NL2. Both groups increased SII to values that were not significantly different from prescription. The hearing aid users, but not the nonusers, increased high-frequency output and SII significantly after taking the speech perception test. Seventeen of the 26 participants (65%) met an SII criterion of 60% under the generic starting condition. The proportion increased to 23 out of 26 (88%) after the final self-adjustment. Of the 13 hearing aid users, 8 (62%) met the 60% criterion with their existing hearing aids. With the final self-adjustment, 12 out of 13 (92%) met this criterion. The findings support the conclusion that user self-adjustment of basic amplification characteristics can be both feasible and effective with or without prior hearing aid experience.

Community-based HIV/AIDS interventions to promote psychosocial well-being among people living with HIV/AIDS: a literature review

PubMed Central

Wu, Liyun; Li, Xiaoming

2013-01-01

Background: This review explores the current community-based psychosocial interventions among people living with HIV/AIDS (PLWHA) across the globe. Methods: Evaluation studies were retrieved and reviewed regarding study location, characteristics of participants, study design, intervention strategies, outcome indicators, and intervention findings. Results: The 28 studies spanned a broad range of intervention strategies, including coping skills, treatment and cure, cultural activities, community involvement, knowledge education, voluntary counseling and testing, peer-group support, three-layered service provision, child-directed group intervention, adult mentoring, and support group interventions. Regardless of study designs, all studies reported positive intervention effects, ranging from a reduction in HIV/AIDS stigma, loneliness, marginalization, distress, depression, anger, and anxiety to an increase in self-esteem, self-efficacy, coping skills, and quality of life. Conclusion: Although the existing studies have limitation with regard to program coverage, intensity, scope, and methodological challenges, they underscore the importance of developing community-based interventions to promote psychosocial well-being among PLWHA. Future studies need to employ more rigorous methodology and integrate contextual and institutional factors when implementing effective interventions. PMID:25264499

A 29.5% efficient perovskite/SiC passivated interdigitated back contact silicon heterojunction (IBC-SiHJ) mechanically stacked tandem solar cell device has been designed and simulated. This is a substantial improvement of 40% and 15%, respectively, compared to the transparent perovskite solar cell (21.1%) and Si solar cell (25.6%) operated individually. The perovskite solar cell has been used as a top subcell, whereas 250- and 25-μm-thick IBC-SiHJ solar cells have been used as bottom subcells. The realistic technology computer aided design analysis has been performed to understand the physical processes in the device and to make reliable predictions of the behavior. The performance of the top subcell has been obtained for different acceptor densities and hole mobility in Spiro-MeOTAD along with the impact of counter electrode work function. To incorporate the effect of material quality, the influence of carrier lifetimes has also been studied for perovskite top and IBC-SiHJ bottom subcells. The optical and electrical behavior of the devices has been obtained for both standalone as well as tandem configuration. Results reported in this study reveal that the proposed four-terminal tandem device may open a new door for cost-effective and energy-efficient applications.

Coaching patients in the use of decision and communication aids: RE-AIM evaluation of a patient support program.

Decision aids educate patients about treatment options and outcomes. Communication aids include question lists, consultation summaries, and audio-recordings. In efficacy studies, decision aids increased patient knowledge, while communication aids increased patient question-asking and information recall. Starting in 2004, we trained successive cohorts of post-baccalaureate, pre-medical interns to coach patients in the use of decision and communication aids at our university-based breast cancer clinic. From July 2005 through June 2012, we used the RE-AIM framework to measure Reach, Effectiveness, Adoption, Implementation and Maintenance of our interventions. 1. Reach: Over the study period, our program sent a total of 5,153 decision aids and directly administered 2,004 communication aids. In the most recent program year (2012), out of 1,524 eligible patient appointments, we successfully contacted 1,212 (80%); coached 1,110 (73%) in the self-administered use of decision and communication aids; sent 958 (63%) decision aids; and directly administered communication aids for 419 (27%) patients. In a 2010 survey, coached patients reported self-administering one or more communication aids in 81% of visits 2. Effectiveness: In our pre-post comparisons, decision aids were associated with increased patient knowledge and decreased decisional conflict. Communication aids were associated with increased self-efficacy and number of questions; and with high ratings of patient preparedness and satisfaction 3. Adoption: Among visitors sent decision aids, 82% of survey respondents reviewed some or all; among those administered communication aids, 86% reviewed one or more after the visit 4. Through continuous quality adaptations, we increased the proportion of available staff time used for patient support (i.e. exploitation of workforce capacity) from 29% in 2005 to 84% in 2012 5. Maintenance: The main barrier to sustainability was the cost of paid intern labor. We addressed this by testing a service learning model in which student interns work as program coaches in exchange for academic credit rather than salary. The feasibility test succeeded, and we are now expanding the use of unpaid interns. We have sustained a clinic-wide implementation of decision and communication aids through a novel staffing model that uses paid and unpaid student interns as coaches.

Clostridium difficile infection (CDI) is the most common cause of infectious diarrhea in health care settings, and for patients presumed to have CDI, their isolation while awaiting laboratory results is costly. Newer rapid tests for CDI may reduce this burden, but the economic consequences of different testing algorithms remain unexplored. We used decision analysis from the hospital perspective to compare multiple CDI testing algorithms for adult inpatients with suspected CDI, assuming patient management according to laboratory results. CDI testing strategies included combinations of on-demand PCR (odPCR), batch PCR, lateral-flow diagnostics, plate-reader enzyme immunoassay, and direct tissue culture cytotoxicity. In the reference scenario, algorithms incorporating rapid testing were cost-effective relative to nonrapid algorithms. For every 10,000 symptomatic adults, relative to a strategy of treating nobody, lateral-flow glutamate dehydrogenase (GDH)/odPCR generated 831 true-positive results and cost $1,600 per additional true-positive case treated. Stand-alone odPCR was more effective and more expensive, identifying 174 additional true-positive cases at $6,900 per additional case treated. All other testing strategies were dominated by (i.e., more costly and less effective than) stand-alone odPCR or odPCR preceded by lateral-flow screening. A cost-benefit analysis (including estimated costs of missed cases) favored stand-alone odPCR in most settings but favored odPCR preceded by lateral-flow testing if a missed CDI case resulted in less than $5,000 of extended hospital stay costs and <2 transmissions, if lateral-flow GDH diagnostic sensitivity was >93%, or if the symptomatic carrier proportion among the toxigenic culture-positive cases was >80%. These results can aid guideline developers and laboratory directors who are considering rapid testing algorithms for diagnosing CDI.

2017-04-01

Borderline personality disorder (BPD) is a debilitating condition, but several psychotherapies are considered effective. To conduct an updated systematic review and meta-analysis of randomized clinical trials to assess the efficacy of psychotherapies for BPD populations. Search terms were combined for borderline personality and randomized trials in PubMed, PsycINFO, EMBASE, and the Cochrane Central Register of Controlled Trials (from database inception to November 2015), as well as the reference lists of earlier meta-analyses. Included were randomized clinical trials of adults with diagnosed BPD randomized to psychotherapy exclusively or to a control intervention. Study selection differentiated stand-alone designs (in which an independent psychotherapy was compared with control interventions) from add-on designs (in which an experimental intervention added to usual treatment was compared with usual treatment alone). Data extraction coded characteristics of trials, participants, and interventions and assessed risk of bias using 4 domains of the Cochrane Collaboration Risk of Bias tool (independent extraction by 2 assessors). Outcomes were pooled using a random-effects model. Subgroup and meta-regression analyses were conducted. Standardized mean differences (Hedges g) were calculated using all outcomes reported in the trials for borderline symptoms, self-harm, suicide, health service use, and general psychopathology at posttest and follow-up. Differential treatment retention at posttest was analyzed, reporting odds ratios. Thirty-three trials (2256 participants) were included. For borderline-relevant outcomes combined (symptoms, self-harm, and suicide) at posttest, the investigated psychotherapies were moderately more effective than control interventions in stand-alone designs (g = 0.32; 95% CI, 0.14-0.51) and add-on designs (g = 0.40; 95% CI, 0.15-0.65). Results were similar for other outcomes, including stand-alone designs: self-harm (g = 0.32; 95% CI, 0.09-0.54), suicide (g = 0.44; 95% CI, 0.15-0.74), health service use (g = 0.40; 95% CI, 0.22-0.58), and general psychopathology (g = 0.32; 95% CI, 0.09-0.55), with no differences between design types. There were no significant differences in the odds ratios for treatment retention (1.32; 95% CI, 0.87-2.00 for stand-alone designs and 1.01; 95% CI, 0.55-1.87 for add-on designs). Thirteen trials reported borderline-relevant outcomes at follow-up (g = 0.45; 95% CI, 0.15-0.75). Dialectical behavior therapy (g = 0.34; 95% CI, 0.15-0.53) and psychodynamic approaches (g = 0.41; 95% CI, 0.12-0.69) were the only types of psychotherapies more effective than control interventions. Risk of bias was a significant moderator in subgroup and meta-regression analyses (slope β = -0.16; 95% CI, -0.29 to -0.03; P = .02). Publication bias was persistent, particularly for follow-up. Psychotherapies, most notably dialectical behavior therapy and psychodynamic approaches, are effective for borderline symptoms and related problems. Nonetheless, effects are small, inflated by risk of bias and publication bias, and particularly unstable at follow-up.

Comparison of two stand-alone CADe systems at multiple operating points

Sahiner, Berkman; Chen, Weijie; Pezeshk, Aria; Petrick, Nicholas

2015-03-01

Computer-aided detection (CADe) systems are typically designed to work at a given operating point: The device displays a mark if and only if the level of suspiciousness of a region of interest is above a fixed threshold. To compare the standalone performances of two systems, one approach is to select the parameters of the systems to yield a target false-positive rate that defines the operating point, and to compare the sensitivities at that operating point. Increasingly, CADe developers offer multiple operating points, which necessitates the comparison of two CADe systems involving multiple comparisons. To control the Type I error, multiple-comparison correction is needed for keeping the family-wise error rate (FWER) less than a given alpha-level. The sensitivities of a single modality at different operating points are correlated. In addition, the sensitivities of the two modalities at the same or different operating points are also likely to be correlated. It has been shown in the literature that when test statistics are correlated, well-known methods for controlling the FWER are conservative. In this study, we compared the FWER and power of three methods, namely the Bonferroni, step-up, and adjusted step-up methods in comparing the sensitivities of two CADe systems at multiple operating points, where the adjusted step-up method uses the estimated correlations. Our results indicate that the adjusted step-up method has a substantial advantage over other the two methods both in terms of the FWER and power.

To use the self-determination theory of motivation to investigate whether different forms of motivation were associated with adults' decisions whether or not to adopt hearing aids. A quantitative approach was used in this cohort study. Participants completed the treatment self-regulation questionnaire (TSRQ), which measured autonomous and controlled motivation for hearing aid adoption. Sociodemographic data and audiometric information were also obtained. Participants were 253 adults who had sought information about their hearing but had not consulted with a hearing professional. Participants were categorized as hearing aid adopters if they had been fitted with hearing aids 4-6 months after completing the TSRQ, and as non-adopters if they had not. Multivariate logistic regression was used to examine associations between autonomous and controlled motivation, sociodemographic and audiometric variables, and hearing aid adoption (n = 160). Three factors were significantly associated with increased hearing aid adoption when the influence of other variables was accounted for: autonomous motivation, perceived hearing difficulty, and poorer hearing. Controlled motivation was not found to influence hearing aid adoption. These empirical findings that link autonomous motivation to decisions of hearing help-seekers have implications for the ways practitioners may evaluate motivation and could inform discussions with clients about hearing aid adoption.

Cross-sectional data were gathered from 1,625 children (M age = 12.85, SD = 2.21) which included 755 AIDS orphans, 466 vulnerable children, and 404 comparison children. Participants completed self-report measures of exposure to traumatic events, and psychosocial adjustment including behavior problems, depression, self-esteem, and future orientation. AIDS orphans and vulnerable children reported experiencing a higher total occurrence, density, duration, initial impact and lasting impact of traumatic events compared to comparison children. Scores reflecting adjustment were lower among orphans and vulnerable children than among comparison children. Both orphan status and traumatic events contributed unique variance in the expected direction to the prediction of psychosocial adjustment. The data in the current study suggested that children affected by HIV/AIDS in China are exposed to more trauma and suffer more adjustment problems than children who do not experience HIV/AIDS in their families.

The purpose of this study was to compare two different methods to teach educators about HIV/AIDS. Sixty educators were selected from eight schools in KwaZulu-Natal Province, South Africa, to undergo HIV/AIDS training using an interactive CD-ROM intervention. Another sixty educators from other schools were selected to undergo a two-day Care & Support Training Programme provided by the Department of Education. The outcomes both before and after the interventions were measured by surveying the educators’ knowledge and attitudes related to HIV/AIDS, as well as their self-efficacy with respect to dealing with HIV/AIDS in the classroom setting. Both interventions resulted in significant changes in knowledge and attitudes as well as in the self-efficacy with respect to ability to teach about HIV/AIDS and to deal with classroom situations involving HIV and blood. The Care & Support Training Programme proved superior in enhancing basic knowledge about HIV, and the CD-ROM was superior in teaching about HIV transmission risks. PMID:20852677

To study the strategy and process of out-hospital emergency care of acute cardiovascular events. One hundred and eighty-three patients in the Second Affiliated Hospital of Baotou Medical College were prospectively studied. The patients were divided into two groups according to the different ways of out-hospital care, one group consisted of patients who received first-aid care after calling "120" (94 cases), another was self-aid group consisting of patients sent to hospital by relatives (89 cases). The proportion of persons with higher than high school education and better knowledge for emergency care of patients with heart disease in first-aid group was higher than self-aid group (50.0% vs. 29.2%, 83.0% vs. 60.7%, both P<0.05). When the patients were brought to the emergency room, they were all treated according to our standard procedure and then registered. All patients were followed up at the end of first and third month after illness. Cardiovascular events were mainly myocardial infarction (61.7%) among 183 patients. There were statistically significant differences between two groups in self-aid response time, first disposal time and out-hospital rescuing time [(32.3+/-5.6) minutes vs. (89.6+/- 8.4) minutes, (47.3+/-7.3) minutes vs. (149.8+/-13.5) minutes, (61.7+/-8.3) minutes vs. [(149.8+/- 13.5) minutes, all P<0.01], but no difference was found in in-hospital rescuing time [(29.9+/-5.3) minutes vs. (31.1+/-4.5) minutes, P>0.05]. Morbidity rate was lower in first-aid group than self-aid group in 1st and 3rd month, respectively (2.1% vs. 9.0%, 4.2% vs. 12.4%, both P<0.05). Excellent emergency system and procedure can shorten initial disposal time and out-hospital rescuing time, thus improve patients' prognosis. The education level and health knowledge of patients and their relatives directly affect their mode of arriving hospital and prognosis.

This paper presents the study and simulation of the self-excited induction generator in the wind power production in isolated sites. With this intention, a model of the wind turbine was established. Extremum-seeking control algorithm method by using Maximum Power Point Tracking (MPPT) is proposed control solution aims at driving the average position of the operating point near to optimality. The reference of turbine rotor speed is adjusted such that the turbine operates around maximum power for the current wind speed value. After a brief review of the concepts of converting wind energy into electrical energy. The proposed modeling tools were developed to study the performance of standalone induction generators connected to capacitor bank. The purpose of this technique is to maintain a constant voltage at the output of the rectifier whatever the loads and speeds. The system studied in this work is developed and tested in MATLAB/Simulink environment. Simulation results validate the performance and effectiveness of the proposed control methods.

Homeless drug users and prostitutes constitute a population at risk for contracting and propagating AIDS. This study aims at understanding the paradox related to drug injection and prostitution among 21 homeless from Montreal. These behaviors are studied following the picoeconomic paradox of an apprehended desire. The results show that these homeless see drug injection as a self-reward motivated by imaginary emotional object, in spite of the known and dreaded consequences. Prostitution is described as a self-investment accessory to drug injection. This study concludes with reflections on AIDS prevention programs in relation with the needs of the homeless.

An online decision aid to support persons having a genetic predisposition to cancer and their partners during reproductive decision-making was developed. A two-phase usability test was conducted among 12 couples (N = 22; 2 persons participated without their partner) at risk for hereditary cancer and 15 health care providers. Couples and health care providers expressed similar suggestions for improvements, and evaluated the modified decision aid as acceptable, easy to use, and comprehensible. The final decision aid was pilot tested (N = 16) with paired sample t tests comparing main outcomes (decisional conflict, knowledge, realistic expectations regarding the reproductive options and decision self-efficacy) before (T0), immediately (T1) and 2 weeks after (T2) use of the decision aid. Pilot testing indicated decreased decisional conflict scores, increased knowledge, and improved realistic expectations regarding the reproductive options, at T1 and T2. No effect was found for couples' decision self-efficacy. The positive findings during usability testing were thus reflected in the pilot study. The decision aid will be further evaluated in a nationwide pretest-posttest study to facilitate implementation in the onco-genetic counselling setting. Ultimately, it is expected that the decision aid will enable end-users to make an informed decision.

Cognitive anchoring on self-generated decisions reduces operator reliance on automated diagnostic aids.

Automation users often disagree with diagnostic aids that are imperfectly reliable. The extent to which users' agreements with an aid are anchored to their personal, self-generated diagnoses was explored. Participants (N = 75) performed 200 trials in which they diagnosed pump failures using an imperfectly reliable automated aid. One group (nonforced anchor, n = 50) provided diagnoses only after consulting the aid. Another group (forced anchor, n = 25) provided diagnoses both before and after receiving feedback from the aid. Within the nonforced anchor group, participants' self-reported tendency to prediagnose system failures significantly predicted their tendency to disagree with the aid, revealing a cognitive anchoring effect. Agreement rates of participants in the forced anchor group indicated that public commitment to a diagnosis did not strengthen this effect. Potential applications include the development of methods for reducing cognitive anchoring effects and improving automation utilization in high-risk domains.

An increasing number of older adults drive automobiles. Given that the prevalence of dementia is rising, it is necessary to address the issue of driving retirement. The purpose of this study is to evaluate how a self-administered decision aid contributed to decision making about driving retirement by individuals living with dementia. The primary outcome measure in this study was decisional conflict. Knowledge, decision, satisfaction with decision, booklet use and booklet acceptability were the secondary outcome measures. A mixed methods approach was adopted. Drivers with dementia were recruited from an Aged Care clinic and a Primary Care center in NSW, Australia. Telephone surveys were conducted before and after participants read the decision aid. Twelve participants were recruited (mean age 75, SD 6.7). The primary outcome measure, decisional conflict, improved following use of the decision aid. Most participants felt that the decision aid: (i) was balanced; (ii) presented information well; and (iii) helped them decide about driving. In addition, mean knowledge scores improved after booklet use. This decision aid shows promise as an acceptable, useful and low-cost tool for drivers with dementia. A self-administered decision aid can be used to assist individuals with dementia decide about driving retirement. A randomized controlled trial is underway to evaluate the effectiveness of the tool.

Abstract Summary: Foldit Standalone is an interactive graphical interface to the Rosetta molecular modeling package. In contrast to most command-line or batch interactions with Rosetta, Foldit Standalone is designed to allow easy, real-time, direct manipulation of protein structures, while also giving access to the extensive power of Rosetta computations. Derived from the user interface of the scientific discovery game Foldit (itself based on Rosetta), Foldit Standalone has added more advanced features and removed the competitive game elements. Foldit Standalone was built from the ground up with a custom rendering and event engine, configurable visualizations and interactions driven by Rosetta. Foldit Standalone contains, among other features: electron density and contact map visualizations, multiple sequence alignment tools for template-based modeling, rigid body transformation controls, RosettaScripts support and an embedded Lua interpreter. Availability and Implementation: Foldit Standalone is available for download at https://fold.it/standalone, under the Rosetta license, which is free for academic and non-profit users. It is implemented in cross-platform C ++ and binary executables are available for Windows, macOS and Linux. Contact: scooper@ccs.neu.edu PMID:28481970

The lipodystrophy syndrome is characterized by selective loss of subcutaneous fat on the face and extremities (lipoatrophy) and/or accumulation of fat around the neck, abdomen, and thorax (lipohypertrophy). The aim of this study has been to assess the impact of polymethylmethacrylate facial treatment on quality of life, self-perceived facial image, and the severity of depressive symptoms in patients living with HIV/AIDS. A non-randomized before and after interventional study was developed. Fifty-one patients underwent facial filling. The self-perceived quality of life, facial image, and degree of depressive symptoms were measured by the Short-Form 36 and HIV/AIDS--Targeted quality of life questionnaires, by a visual analogue scale and by the Beck depression inventory, respectively, before and three months after treatment. Six of the eight domains of Short-Form 36 and eight of the nine dimensions of the HIV/AIDS--Targeted quality of life questionnaires, together with the visual analogue scale and by the Beck depression inventory scores, revealed a statistically significant improvement. The only adverse effects registered were edema and ecchymosis. The treatment of facial lipoatrophy improved the self-perceived quality of life and facial image as well as any depressive symptoms among patients with HIV/AIDS. © 2014 The International Society of Dermatology.

A wearable multipoint ultrasonic travel aids for visually impaired

Ercoli, Ilaria; Marchionni, Paolo; Scalise, Lorenzo

2013-09-01

In 2010, the World Health Organization estimates that there were about 285 million people in the world with disabling eyesight loss (246 millions are visually impaired (VI) and 39 millions are totally blind). For such users, hits during mobility tasks are the reason of major concerns and can reduce the quality of their life. The white cane is the primary device used by the majority of blind or VI users to explore and possibly avoid obstacles; it can monitor only the ground (< 1m) and it does not provide protection for the legs, the trunk and the head. In this paper, authors propose a novel stand-alone Electronic Travel Aid (ETA) device for obstacle detection based on multi- sensing (by 4 ultrasonic transducers) and a microcontroller. Portability, simplicity, reduced dimensions and cost are among the major pros of the reported system, which can detect and localize (angular position and distance from the user) obstacles eventually present in the volume in front of him and on the ground in front of him.

A simple, relatively inexpensive robotic system that can aid severely disabled persons by providing pick-and-place manipulative abilities to augment the functions of human or trained animal assistants is under development at Rice University and the Baylor College of Medicine. A stand-alone software application program runs on a Macintosh personal computer and provides the user with a selection of interactive windows for commanding the mobile robot via cursor action. A HERO 2000 robot has been modified such that its workspace extends from the floor to tabletop heights, and the robot is interfaced to a Macintosh SE via a wireless communications link for untethered operation. Integrated into the system are hardware and software which allow the user to control household appliances in addition to the robot. A separate Machine Control Interface device converts breath action and head or other three-dimensional motion inputs into cursor signals. Preliminary in-home and laboratory testing has demonstrated the utility of the system to perform useful navigational and manipulative tasks.

An Overview of a Trajectory-Based Solution for En Route and Terminal Area Self-Spacing: Third Revision

NASA Technical Reports Server (NTRS)

Abbott, Terence S.

2012-01-01

This paper presents an overview of the third major revision to an algorithm specifically designed to support NASA's Airborne Precision Spacing concept. This algorithm is referred to as the Airborne Spacing for Terminal Arrival Routes version 11 (ASTAR11). This airborne self-spacing concept is trajectory-based, allowing for spacing operations prior to the aircraft being on a common path. Because this algorithm is trajectory-based, it also has the inherent ability to support required time-of-arrival (RTA) operations. This algorithm was also designed specifically to support a standalone, non-integrated implementation in the spacing aircraft.

Research in the developed world suggests that parental alcohol use negatively impacts child mental health. However, little research has examined these relations among children in the developing world and no studies to date have done so in the context of AIDS-orphanhood. Therefore, the present study tested the interactive effect of AIDS-orphan status with caregiver alcohol use on child mental health. The sample included 742 children (51.2% female; M age   = 9.18; age range: 7-11 years; 29.8 AIDS-orphans; 36.8% orphaned by causes other than AIDS; 33.4% non-orphaned) recruited from Mangaung in the Free State Province of South Africa. Child mental health was assessed via child self-report, caregiver, and teacher reports; and caregiver alcohol use via self-report. Path analyses, via structural equation modeling, revealed significant direct effects for AIDS-orphan status on caregiver-reported child mental health; and for caregiver alcohol-use problems on teacher-reported child mental health. However, the interaction effect of AIDS-orphan status with caregiver alcohol use did not reach significance on all three reports of child mental health problems. These results suggest that orphan status and caregiver alcohol use may independently relate to mental health problems in children and that the effects of both should be considered in the context of the mental health needs of children in AIDS-affected countries.

Case studies of memory-impaired individuals consistently show that reminiscing with SenseCam images enhances event recall. This exploratory study examined whether a similar benefit would occur for the consolidation of memories in memory-unimpaired people. We tested delayed recall for atypical actions observed on a lengthy walk. Participants used SenseCam, a diary, or no external memory aid while walking, followed by reminiscence with SenseCam images, diary entries, or no aid, either alone (self-reminiscence) or with the experimenter (social reminiscence). One week later, when tested without SenseCam images or diary entries, prior social reminiscence produced greater recall than self-reminiscence, but there were no differences between memory aid conditions for action free recall or action order recall. When methodological variables were controlled, there was no recall advantage for SenseCam reminiscence with memory-unimpaired participants. The case studies and present study differ in multiple ways, making direct comparisons problematic. SenseCam is a valuable aid to the memory impaired, but its mnemonic value for non-clinical populations remains to be determined.

To describe patterns of experimentation with electronic cigarettes as a smoking cessation aid, their self-reported impact on smoking cessation and to identify factors associated with self-reported successful quit attempts within the European Union (EU). A cross-sectional study. 28 European Union member states. We analysed data from wave 82.4 of the Special Eurobarometer survey, collected in December 2014 from all 28 EU member states. The total sample size was n=27 801 individuals aged ≥15 years; however, our analyses were conducted in different subgroups with sample sizes ranging from n=470 to n=9363. Data on e-cigarette experimentation and its self-reported impact on smoking cessation were collected. Logistic regression models were used to assess factors associated with experimentation of e-cigarettes as cessation aids and with successful quitting. Logistic regression was also used to assess changes in the use of e-cigarettes as cessation aids between 2012 (using data from wave 77.1 of the Eurobarometer) and 2014 in each member state. E-cigarettes were often experimented with as a cessation aid, especially among younger smokers (OR=5.29) and those who reported financial difficulties (OR=1.33). In total, 10.6% of those who had ever attempted to quit smoking and 27.4% of those who did so using a cessation aid had experimented with e-cigarettes as a cessation aid. Among those who had used e-cigarettes as a cessation aid, those with higher education were more likely to have been successful in quitting (OR=2.23). There was great variation in trends of use of e-cigarette as a cessation aid between member states. Experimentation with e-cigarettes as a potential cessation aid at a population level has increased throughout the EU in recent years, and certain population groups are more likely to experiment with them as cessation aids. Research on the potential population impact of these trends is imperatively needed. Published by the BMJ Publishing Group Limited.

Identifying work ability promoting factors for home care aides and assistant nurses

PubMed Central

2012-01-01

Background In workplace health promotion, all potential resources needs to be taken into consideration, not only factors relating to the absence of injury and the physical health of the workers, but also psychological aspects. A dynamic balance between the resources of the individual employees and the demands of work is an important prerequisite. In the home care services, there is a noticeable trend towards increased psychosocial strain on employees at work. There are a high frequency of work-related musculoskeletal disorders and injuries, and a low prevalence of sustainable work ability. The aim of this research was to identify factors promoting work ability and self-efficacy in care aides and assistant nurses within home care services. Methods This study is based on cross-sectional data collected in a municipality in northern Sweden. Care aides (n = 58) and assistant nurses (n = 79) replied to a self-administered questionnaire (response rate 46%). Hierarchical multiple regression analyses were performed to assess the influence of several independent variables on self-efficacy (model 1) and work ability (model 2) for care aides and assistant nurses separately. Results Perceptions of personal safety, self-efficacy and musculoskeletal wellbeing contributed to work ability for assistant nurses (R2adj of 0.36, p < 0.001), while for care aides, the safety climate, seniority and age contributed to work ability (R2adj of 0.29, p = 0.001). Self-efficacy was associated with the safety climate and the physical demands of the job in both professions (R2adj of 0.24, p = 0.003 for care aides), and also by sex and age for the assistant nurses (R2adj of 0.31, p < 0.001). Conclusions The intermediate factors contributed differently to work ability in the two professions. Self-efficacy, personal safety and musculoskeletal wellbeing were important for the assistant nurses, while the work ability of the care aides was associated with the safety climate, but also with the non-changeable factors age and seniority. All these factors are important to acknowledge in practice and in further research. Proactive workplace interventions need to focus on potentially modifiable factors such as self-efficacy, safety climate, physical job demands and musculoskeletal wellbeing. PMID:22236253

2007-08-01

Various studies indicate that school- or university-based HIV prevention curricula can reduce the prevalence of sexual risk behaviour among adolescent youth in Sub-Saharan Africa. However, effective HIV/AIDS prevention education may be problematic, if the needs of youth are not served adequately. To date, little attention has been given to the motivation of youth to learn about HIV/AIDS and about their preferences for HIV/AIDS curriculum design options. The aim of this study was to get insight into the determinants of the motivation of youth to learn about HIV/AIDS prevention and to assess their curriculum design preferences. Students from a university in Tigray, Ethiopia, filled out a structured questionnaire, which assessed demographics, variables that according to the Theory of Planned Behaviour are related to the motivation to learn, and their preferences for independent, carrier and integrated HIV/AIDS curriculum designs. On average, participants were highly motivated to learn about HIV/AIDS. Motivation to learn was primarily related to social norms and was not related to self-efficacy to discuss HIV/AIDS in class. The often discussed reluctance to discuss sexuality and condom use in curricula in Sub-Saharan Africa, seems to be more related to existing negative social norms, than to lack of self-efficacy. Participants revealed a high preference for the independent, carrier and integrated curriculum design options. However, students with a higher motivation to learn about HIV/AIDS were more attracted to the independent course design.

Objective We estimate the prevalence of hearing-aid use in Iceland and identify sex-specific factors associated with use. Design Population-based cohort study. Study sample A total of 5172 age, gene/environment susceptibility - Reykjavik study (AGES-RS) participants, aged 67 to 96 years (mean age 76.5 years), who completed air-conduction and pure-tone audiometry. Results Hearing-aid use was reported by 23.0% of men and 15.9% of women in the cohort, although among participants with at least moderate hearing loss in the better ear (pure-tone average [PTA] of thresholds at 0.5, 1, 2, and 4 kHz ≥ 35 dB hearing level [HL]) it was 49.9% and did not differ by sex. Self-reported hearing loss was the strongest predictor of hearing-aid use in men [OR: 2.68 (95% CI: 1.77, 4.08)] and women [OR: 3.07 (95% CI: 1.94, 4.86)], followed by hearing loss severity based on audiometry. Having diabetes or osteoarthritis were significant positive predictors of use in men, whereas greater physical activity and unimpaired cognitive status were important in women. Conclusions Hearing-aid use was comparable in Icelandic men and women with moderate or greater hearing loss. Self-recognition of hearing loss was the factor most predictive of hearing-aid use; other influential factors differed for men and women. PMID:25816699

One-third of adults living with HIV/AIDS are over the age of 50. This study evaluated the structure of coping among 307 older adults living with HIV/AIDS. Participants completed 61 coping items and measures of anxiety, depression, loneliness, and coping self-efficacy. Exploratory factor analyses retained 40 coping items loading on five specific first order factors (Distancing Avoidance, Social Support Seeking, Self-Destructive Avoidance, Spiritual Coping, and Solution-Focused Coping) and two general second order factors (Active and Avoidant Coping). Factors demonstrated good reliability and validity. Results suggest that general coping factors should be considered with specific factors when measuring coping among older adults. PMID:22453164

2017-07-01

This scoping review aims to determine the size and scope of the published literature on shared decision-making (SDM) using personal health record (PHR) technology and to map the literature in terms of system design and outcomes. Literature from Medline, Google Scholar, Cumulative Index to Nursing and Allied Health Literature, Engineering Village, and Web of Science (2005-2015) using the search terms "personal health records," "shared decision making," "patient-provider communication," "decision aid," and "decision support" was included. Articles ( n  = 38) addressed the efficacy or effectiveness of PHRs for SDM in engaging patients in self-care and decision-making or ways patients can be supported in SDM via PHR. Analysis resulted in an integrated SDM-PHR conceptual framework. An increased interest in SDM via PHR is apparent, with 55% of articles published within last 3 years. Sixty percent of the literature originates from the United States. Twenty-six articles address a particular clinical condition, with 10 focused on diabetes, and one-third offer empirical evidence of patient outcomes. The tethered and standalone PHR architectural types were most studied, while the interconnected PHR type was the focus of more recently published methodological approaches and discussion articles. The study reveals a scarcity of rigorous research on SDM via PHR. Research has focused on one or a few of the SDM elements and not on the intended complete process. Just as PHR technology designed on an interconnected architecture has the potential to facilitate SDM, integrating the SDM process into PHR technology has the potential to drive PHR value. © The Author 2017.

Ethanol production from lignocellulosic materials is often conceived considering independent, stand-alone production plants; in the Brazilian scenario, where part of the potential feedstock (sugarcane bagasse) for second generation ethanol production is already available at conventional first generation production plants, an integrated first and second generation production process seems to be the most obvious option. In this study stand-alone second generation ethanol production from surplus sugarcane bagasse and trash is compared with conventional first generation ethanol production from sugarcane and with integrated first and second generation; simulations were developed to represent the different technological scenarios, which provided data for economic and environmental analysis. Results show that the integrated first and second generation ethanol production process from sugarcane leads to better economic results when compared with the stand-alone plant, especially when advanced hydrolysis technologies and pentoses fermentation are included.

2011-01-01

A self-fitting hearing aid, designed to be assembled and programmed without audiological or computer support, could bring amplification to millions of people in developing countries, who remain unaided due to the lack of a local, professional, audiological infrastructure. The ability to assemble and insert a hearing aid is fundamental to the successful use of a self-fitting device. In this study, the management of such tasks was investigated. Eighty older, urban-dwelling, hearing-impaired adults in a developed country were asked to follow a set of written, illustrated instructions to assemble two slim-fit behind-the-ear hearing aids. Participants were allowed to access assistance with the task from an accompanying partner. A range of personal and audiometric variables was measured through the use of structured questionnaires and standardized tests of health literacy, cognitive function, and manual dexterity. The results showed that 99% of participants were able to complete the hearing aid assembly task, either on their own or with assistance. Health literacy, or the ability to read and understand health-related text, and gender most strongly influenced participants’ ability to complete the assembly task independently and accurately. Higher levels of health literacy were associated with an increased likelihood of independent and successful task completion. Male participants were more likely to complete the task on their own, while female participants were more likely to assemble the device without errors. The results of this study will inform future work regarding development of educational material for the self-fitting hearing aid as well as candidacy for such a device. PMID:22200734

Mindfulness meditation training is garnering increasing empirical interest as an intervention for ADHD in adulthood, although no studies of mindfulness as a standalone treatment have included a sample composed entirely of adults with ADHD or a comparison group. The aim of this study was to assess the feasibility, acceptability, and preliminary efficacy of mindfulness meditation for ADHD, executive functioning (EF), and emotion dysregulation symptoms in an adult ADHD sample. Adults with ADHD were stratified by ADHD medication status and otherwise randomized into an 8-week group-based mindfulness treatment ( n = 11) or waitlist group ( n = 9). Treatment feasibility and acceptability were positive. In addition, self-reported ADHD and EF symptoms (assessed in the laboratory and ecological momentary assessment), clinician ratings of ADHD and EF symptoms, and self-reported emotion dysregulation improved for the treatment group relative to the waitlist group over time with large effect sizes. Improvement was not observed for EF tasks. Findings support preliminary treatment efficacy, though require larger trials.

An Overview of a Trajectory-Based Solution for En Route and Terminal Area Self-Spacing: Sixth Revision

NASA Technical Reports Server (NTRS)

Abbott, Terence S.

2015-01-01

This paper presents an overview of the sixth revision to an algorithm specifically designed to support NASA's Airborne Precision Spacing concept. This algorithm is referred to as the Airborne Spacing for Terminal Arrival Routes version 13 (ASTAR13). This airborne self-spacing concept contains both trajectory-based and state-based mechanisms for calculating the speeds required to achieve or maintain a precise spacing interval. The trajectory-based capability allows for spacing operations prior to the aircraft being on a common path. This algorithm was also designed specifically to support a standalone, non-integrated implementation in the spacing aircraft. This current revision to the algorithm adds the state-based capability in support of evolving industry standards relating to airborne self-spacing.

Background: The purpose of this study was to evaluate the influence of three different luting protocols on shear bond strength of computer aided design/computer aided manufacturing (CAD/CAM) resin nanoceramic (RNC) material to dentin. Materials and Methods: In this in vitro study, 30 disks were milled from RNC blocks (Lava Ultimate/3M ESPE) with CAD/CAM technology. The disks were subsequently cemented to the exposed dentin of 30 recently extracted bovine permanent mandibular incisors. The specimens were randomly assigned into 3 groups of 10 teeth each. In Group 1, disks were cemented using a total-etch protocol (Scotchbond™ Universal Etchant phosphoric acid + Scotchbond Universal Adhesive + RelyX™ Ultimate conventional resin cement); in Group 2, disks were cemented using a self-etch protocol (Scotchbond Universal Adhesive + RelyX™ Ultimate conventional resin cement); in Group 3, disks were cemented using a self-adhesive protocol (RelyX™ Unicem 2 Automix self-adhesive resin cement). All cemented specimens were placed in a universal testing machine (Instron Universal Testing Machine 3343) and submitted to a shear bond strength test to check the strength of adhesion between the two substrates, dentin, and RNC disks. Specimens were stressed at a crosshead speed of 1 mm/min. Data were analyzed with analysis of variance and post-hoc Tukey's test at a level of significance of 0.05. Results: Post-hoc Tukey testing showed that the highest shear strength values (P < 0.001) were reported in Group 2. The lowest data (P < 0.001) were recorded in Group 3. Conclusion: Within the limitations of this in vitro study, conventional resin cements (coupled with etch and rinse or self-etch adhesives) showed better shear strength values compared to self-adhesive resin cements. Furthermore, conventional resin cements used together with a self-etch adhesive reported the highest values of adhesion. PMID:27076822

Secker, Lisanne J; Bergman, Wilma; Kukutsch, Nicole A

2016-02-01

Skin self-examination can help patients who are at high risk for developing melanoma to become more involved in their own surveillance and treatment. This study examined the use of total body photography as an aid to skin self-examination from the patients' perspective. A total of 179 individuals at high risk for developing melanoma who had undergone total body photography (60.5% response rate) completed a self-reported questionnaire assessing the frequency of skin self-examination, perceived usefulness of total body photography, and a variety of potential demographic, clinical and psychological factors. Only approximately half of the participants indicated skin self-examination as useful and 78.9% preferred clinical skin examination by a specialist. Finding total body photography useful was associated with having received instructions on how to perform skin self-examination, the use of a (hand)mirror, and confidence to detect changing moles. These findings allow us to develop strategies to further improve patients' self-screening behaviours.

Individuals who engage in nonsuicidal self-injury (NSSI) may prefer the Internet as a medium to communicate about NSSI experiences and obtain NSSI information. Recent research suggests that NSSI first aid information is shared. Yet, no research has examined the context in which this information occurs. This study examined the nature and scope of NSSI first aid tips on YouTube using a content analysis to examine 40 NSSI first aid videos. Findings indicated that videos were viewed 157,571 total times; they were typically favorably viewed. Most had a neutral purpose and neither encouraged nor discouraged NSSI. Messages encouraging NSSI help seeking were scant. Similarly, medical help seeking was not commonly encouraged, with several videos providing "safe" NSSI instructions. Overall, videos with NSSI first aid information may contribute to NSSI reinforcement and the belief that professional and medical help may not be needed for NSSI. Findings have implications for research, clinical work, and e-outreach, which are discussed.

Doku, P N; Minnis, H

2016-08-01

There is little knowledge about the psychosocial distress of children affected by human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) in Ghana, to aid the planning of services. This study investigated mental health problems among children affected by HIV/AIDS, compared with control groups of children orphaned by other causes, and non-orphans. The study employed a cross-sectional survey that interviewed 291 children and their caregivers. Both children and caregivers completed the Strengths and Difficulties Questionnaire that measured children's psychosocial wellbeing. Verbal autopsy was used to identify whether children lost one or both parents from AIDS. The results indicated that controlling for relevant sociodemographic factors, both children's self-reports and caregivers' reports indicate that both children living with HIV/AIDS-infected caregivers and children orphaned by AIDS were at heightened risk for mental health problems than both children orphaned by other causes and non-orphans. The findings further indicated that a significant proportion of orphaned and vulnerable children exhibited symptoms for depression and other psychiatric disorders (approximately 63%) compared with 7% among the non-orphaned group. Caregivers gave higher ratings for children on externalizing problems and lower on internalizing problems, and vice versa when the children's self-reports were analysed. The findings suggest that both children and their informants have diverse yet complementary perspectives on psychological outcomes. The study discusses the theoretical and practical implications of these findings and urgently calls for necessary intervention programmes that target all children affected by HIV/AIDS to effectively alleviate psychological distress and enhance the mental health of these children.

Computer-aided detection and diagnosis (CAD) systems are increasingly being used as an aid by clinicians for detection and interpretation of diseases. Computer-aided detection systems mark regions of an image that may reveal specific abnormalities and are used to alert clinicians to these regions during image interpretation. Computer-aided diagnosis systems provide an assessment of a disease using image-based information alone or in combination with other relevant diagnostic data and are used by clinicians as a decision support in developing their diagnoses. While CAD systems are commercially available, standardized approaches for evaluating and reporting their performance have not yet been fully formalized in the literature or in a standardization effort. This deficiency has led to difficulty in the comparison of CAD devices and in understanding how the reported performance might translate into clinical practice. To address these important issues, the American Association of Physicists in Medicine (AAPM) formed the Computer Aided Detection in Diagnostic Imaging Subcommittee (CADSC), in part, to develop recommendations on approaches for assessing CAD system performance. The purpose of this paper is to convey the opinions of the AAPM CADSC members and to stimulate the development of consensus approaches and "best practices" for evaluating CAD systems. Both the assessment of a standalone CAD system and the evaluation of the impact of CAD on end-users are discussed. It is hoped that awareness of these important evaluation elements and the CADSC recommendations will lead to further development of structured guidelines for CAD performance assessment. Proper assessment of CAD system performance is expected to increase the understanding of a CAD system's effectiveness and limitations, which is expected to stimulate further research and development efforts on CAD technologies, reduce problems due to improper use, and eventually improve the utility and efficacy of CAD in clinical practice.

Although links between HIV-related stigma and self-disclosure of HIV status among people living with HIV have been well established, it is unclear whether levels of perceived discrimination are differentially associated with self-disclosure. The present study using a multi-factorial survey design investigated the role of stigma and other self-related factors (e.g., anticipated discrimination, self-esteem, HIV-related factors [e.g., drug use combination; knowledge of duration of HIV diagnosis] and socio-demographic factors [e.g., multiple spouse; age, gender, educational level] and psychological distress [depression]) in self-disclosure among People living with HIV/AIDs has been added (PLWHA) on follow-up management in State Specialist Hospital Akure, Nigeria. One hundred and thirty nine HIV/AIDS patients (49 males and 90 females) participated in the study. Mean age and mean time in months since diagnosis were 39.56 ± 10.26 and 37.78 ± 48.34, respectively. Four variables: multiple spouse, anticipated discrimination, HIV-related stigma and self-esteem were related to self-disclosure at (p < .05). Product-term regression analyses demonstrated that perceived discrimination mediated the relationship between self-esteem (Sobel test: z = 2.09, Aroian = 2.06, p < .001), perceived stigma (Sobel test: z = 2.78, Aroaian = 2.75 p < .01) and self-disclosure. Interaction term analysis between HIV-related stigma t (5, 137) = 1.69, p > .05, self-esteem t (5, 137) = .59, p > .05 and anticipated discrimination were non-significant, suggesting a non-moderation effect of discrimination and disclosure. The results indicate that anticipated discrimination may impact HIV-related stigma to reduce self-disclosure among the PLWHAs in Akure, Nigeria. Interventions should incorporate anticipated discrimination in educational programs of HIV stigma in encouraging self-disclosure among PLWHAs.

This study evaluates the environmental impacts of biorefinery products using consequential (CLCA) and attributional (ALCA) life cycle assessment (LCA) approaches. Within ALCA, economic allocation method was used to distribute impacts among the main products and the coproducts, whereas within the CLCA system expansion was adopted to avoid allocation. The study seeks to answer the questions (i) what is the environmental impacts of process integration?, and (ii) do CLCA and ALCA lead to different conclusions when applied to biorefinery?. Three biorefinery systems were evaluated and compared: a standalone system producing bioethanol from winter wheat-straw (system A), a standalone system producing biobased lactic acid from alfalfa (system B), and an integrated biorefinery system (system C) combining the two standalone systems and producing both bioethanol and lactic acid. The synergy of the integration was the exchange of useful energy necessary for biomass processing in the two standalone systems. The systems were compared against a common reference flow: "1MJ EtOH +1kg LA ", which was set on the basis of products delivered by the system C. Function of the reference flow was to provide service of both fuel (bioethanol) at 99.9% concentration (wt. basis) and biochemical (biobased lactic acid) in food industries at 90% purity; both products delivered at biorefinery gate. The environmental impacts of interest were global warming potential (GWP 100 ), eutrophication potential (EP), non-renewable energy (NRE) use and the agricultural land occupation (ALO). Regardless of the LCA approach adopted, system C performed better in most of the impact categories than both standalone systems. The process wise contribution to the obtained environmental impacts also showed similar impact pattern in both approaches. The study also highlighted that the recirculation of intermediate materials, e.g. C 5 sugar to boost bioethanol yield and that the use of residual streams in the energy conversion were beneficial for optimizing the system performance.

Autzen, Henriette Elisabeth; Musgaard, Maria

2016-01-01

Molecular dynamics (MD) simulation is a computational method which provides insight on protein dynamics with high resolution in both space and time, in contrast to many experimental techniques. MD simulations can be used as a stand-alone method to study P-type ATPases as well as a complementary method aiding experimental studies. In particular, MD simulations have proved valuable in generating and confirming hypotheses relating to the structure and function of P-type ATPases. In the following, we describe a detailed practical procedure on how to set up and run a MD simulation of a P-type ATPase embedded in a lipid bilayer using software free of use for academics. We emphasize general considerations and problems typically encountered when setting up simulations. While full coverage of all possible procedures is beyond the scope of this chapter, we have chosen to illustrate the MD procedure with the Nanoscale Molecular Dynamics (NAMD) and the Visual Molecular Dynamics (VMD) software suites.

Impact of a cell phone intervention on mediating mechanisms of smoking cessation in individuals living with HIV/AIDS.

Vidrine, Damon J; Arduino, Roberto C; Gritz, Ellen R

2006-12-01

Mounting evidence suggests that smokers living with HIV/AIDS have a significantly increased risk of numerous adverse health outcomes (both AIDS- and non-AIDS-related) compared with HIV-positive nonsmokers. Therefore, efforts to design and implement effective cessation programs for this ever-growing special population are warranted. The present study assessed the effects of a cell phone intervention (CPI) on hypothesized mediators (i.e., changes in depression, anxiety, social support, and self-efficacy) demonstrated to influence cessation outcomes in other populations. Ninety-five participants from an inner-city AIDS clinic were randomized to receive either the CPI or recommended standard of care (RSOC) smoking cessation treatment. Participants randomized to the RSOC group (n=47) received brief advice to quit, a 10-week supply of nicotine patches, and self-help materials. Participants randomized to the CPI group (n=48) received RSOC components plus a series of eight proactive counseling sessions delivered via cell phones. A series of regression analyses (linear and logistic) was used to assess the relationships between treatment group, the hypothesized mediators, and biochemically confirmed smoking cessation outcomes. Results indicated that the CPI group experienced greater reductions in anxiety and depression, and increases in self-efficacy compared with the RSOC group. Further, changes in depression, anxiety, and self-efficacy weakened the association between treatment group and cessation outcome. The mediator hypothesis, however, for social support was rejected, as the difference score was not significantly associated with treatment group. These results suggest that the efficacy of the CPI is at least partially mediated by its ability to decrease symptoms of distress while increasing self-efficacy.

Testing a Spanish-language colorectal cancer screening decision aid in Latinos with limited English proficiency: results from a pre-post trial and four month follow-up survey.

Compared with non-Latinos, Latinos in the US have low rates of colorectal cancer (CRC) screening and low rates of knowledge regarding CRC screening tests and guidelines. Spanish speaking Latinos have particularly low CRC screening rates and screening knowledge. Our purpose was twofold: (1) to evaluate the effect of a computer-based, Spanish-language CRC screening decision aid on screening knowledge, intent to obtain screening, and screening self-efficacy in a community sample of Latinos with limited English proficiency (LEP); and (2) to survey these decision aid viewers at four months to determine their rates of CRC discussions with a health care provider as well as their rates of screening test completion. We recruited 50-75 year old Latinos with LEP who were not current with CRC. Participants screening viewed a 14 minute multimedia decision aid that addresses CRC screening rationale, recommendations, and options. We conducted an uncontrolled (pre-post) study in which we assessed screening knowledge, self-efficacy, and intent at baseline and immediately after decision aid viewing. We also conducted a follow-up telephone survey of participants at four months to examine rates of patient-provider screening discussions and test completion. Among n = 80 participants, knowledge scores increased from 20% (before) to 72% (after) decision aid viewing (absolute difference [95%CI]: 52% [46, 59]). The proportion with high screening self-efficacy increased from 67% to 92% (25% [13, 37]); the proportion with high screening intent increased from 63% to 95% (32% [21, 44]). We reached 68 (85%) of 80 participants eligible for the follow-up survey. Of these 36 (53%) reported discussing screening with a provider and 13 (19%) completed a test. Viewing a Spanish-language decision aid increased CRC screening knowledge, self-efficacy, and intent among Latinos with LEP. Decision aid viewing appeared to promote both CRC screening discussions with health care providers and test completion. The decision aid may be an effective tool for promoting CRC screening and reducing screening disparities in this population.

Community health workers (CHWs) may be an important mechanism to provide diabetes self-management to disadvantaged populations. We describe the design and baseline results of a trial evaluating a home-based CHW intervention. Peer Support for Achieving Independence in Diabetes (Peer-AID) is a randomized, controlled trial evaluating a home-based CHW-delivered diabetes self-management intervention versus usual care. The study recruited participants from 3 health systems. Change in A1c measured at 12 months is the primary outcome. Changes in blood pressure, lipids, health care utilization, health-related quality of life, self-efficacy and diabetes self-management behaviors at 12 months are secondary outcomes. A total of 1438 patients were identified by a medical record review as potentially eligible, 445 patients were screened by telephone for eligibility and 287 were randomized. Groups were comparable at baseline on socio-demographic and clinical characteristics. All participants were low-income and were from diverse racial and ethnic backgrounds. The mean A1c was 8.9%, mean BMI was above the obese range, and non-adherence to diabetes medications was high. The cohort had high rates of co-morbid disease and low self-reported health status. Although one-third reported no health insurance, the mean number of visits to a physician in the past year was 5.7. Trial results are pending. Peer-AID recruited and enrolled a diverse group of low income participants with poorly controlled type 2 diabetes and delivered a home-based diabetes self-management program. If effective, replication of the Peer-AID intervention in community based settings could contribute to improved control of diabetes in vulnerable populations. Published by Elsevier Inc.

The study recruited participants from 3 health systems. Change in A1c measured at 12 months is the primary outcome. Change in blood pressure, lipids, health care utilization, health-related quality of life, self-efficacy and diabetes self-management behaviors at 12 months are secondary outcomes. Results A total of 1,438 patients were identified by medical record review as potentially eligible, 445 patients were screened by telephone for eligibility and 287 were randomized. Groups were comparable at baseline on socio-demographic and clinical characteristics. All participants were low-income and were from diverse racial and ethnic backgrounds. The mean A1c was 8.9%, mean BMI was above the obese range, and non-adherence to diabetes medications was high. The cohort had high rates of co-morbid disease and low self-reported health status. Although one-third reported no health insurance, the mean number of visits to a physician in the past year was 5.7. Trial results are pending. Conclusions Peer-AID recruited and enrolled a diverse group of low income participants with poorly controlled type 2 diabetes and delivered a home-based diabetes self-management program. If effective, replication of the Peer-AID intervention in community based settings could contribute to improved control of diabetes in vulnerable populations. PMID:24956324

Hearing aid patients in private practice and public health (Veterans Affairs) clinics: are they different?

In hearing aid research, it is commonplace to combine data across subjects whose hearing aids were provided in different service delivery models. There is reason to question whether these types of patients are always similar enough to justify this practice. To explore this matter, this investigation evaluated similarities and differences in self-report data obtained from hearing aid patients derived from public health (Veterans Affairs, VA) and private practice (PP) settings. The study was a multisite, cross-sectional survey in which 230 hearing aid patients from VA and PP audiology clinic settings provided self-report data on a collection of questionnaires both before and after the hearing aid fitting. Subjects were all older adults with mild to moderately severe hearing loss. About half of them had previous experience wearing hearing aids. All subjects were fitted with wide-dynamic-range-compression instruments and received similar treatment protocols. Numerous statistically significant differences were observed between the VA and PP subject groups. Before the fitting, VA patients reported higher expectations from the hearing aids and more severe unaided problems compared with PP patients with similar audiograms. Three wks after the fitting, VA patients reported more satisfaction with their hearing aids. On some measures VA patients reported more benefit, but different measures of benefit did not give completely consistent results. Both groups reported using the hearing aids an average of approximately 8 hrs per day. VA patients reported age-normal physical and mental health, but PP patients tended to report better than typical health for their age group. These data indicate that hearing aid patients seen in the VA public health hearing services are systematically different in self-report domains from those seen in private practice services. It is therefore risky to casually combine data from these two types of subjects or to generalize research results from one group to the other. Further, compared with PP patients, VA patients consistently reported more favorable hearing aid fitting outcomes. Additional study is indicated to explore the determinants of this result and its generalizability to other public health service delivery systems such as those in other countries. Moreover, efforts should be made to assess the potential for transferring positive elements from the VA system to the PP service delivery system, if possible.

Handicap versus impairment: an important distinction.

PubMed

Weinstein, B E; Richards, A M; Montano, J

In this era of spiraling health care costs, audiologists are being held accountable for the rehabilitative interventions that they are uniquely qualified to deliver. Accountability data in the rehabilitative arena should address the efficacy of short- and long-term treatment. If a treatment such as a hearing aid is dispensed for the purpose of reducing the communicative and psychosocial handicap associated with hearing loss, efficacy data should demonstrate whether such a goal has been attained. Increased attention has been focused on the value of self-assessment questionnaires as instruments that are predictive of candidacy for hearing aids, intent to purchase hearing aids, and outcomes with a given hearing aid treatment. Case studies demonstrate the advantage of engaging the client in the rehabilitative process through the use of responses to self-assessment questionnaires. It is evident that the client's appraisal of the handicapping effect of a given impairment is associated with treatment efficacy.

This study presents a simple and sustainable Microbial Fuel Cell as a standalone, self-powered reactor for in situ wastewater electrolysis, recovering nitrogen from wastewater. A process is proposed whereby the MFC electrical performance drives the electrolysis of wastewater towards the self-generation of catholyte within the same reactor. The MFCs were designed to harvest the generated catholyte in the internal chamber, which showed that liquid production rates are largely proportional to electrical current generation. The catholyte demonstrated bactericidal properties, compared to the control (open-circuit) diffusate, and reduced observable biofilm formation on the cathode electrode. Killing effects were confirmed using bacterial kill curves constructed by exposing a bioluminescent Escherichia coli target, as a surrogate coliform, to catholyte where a rapid kill rate was observed. Therefore, MFCs could serve as a water recovery system, a disinfectant/cleaner generator that limits undesired biofilm formation and as a washing agent in waterless urinals to improve sanitation. This simple and ready to implement MFC system can convert organic waste directly into electricity and self-driven nitrogen along with water recovery. This could lead to the development of energy positive bioprocesses for sustainable wastewater treatment.

Knowledge regarding compliance patterns and service utilization in e-health is important for the development of effective services. To develop proper e-health, the characteristics of compliance patterns and utilization of e-health should be studied. We studied these for glucose monitoring of diabetic patients from primary clinics. Data were collected from 160 outpatients who participated in e-health for glucose monitoring funded by the Korean government. Specifically, this study focused on two device types: a standalone Internet gateway and a tablet device. The SPSS 18.0 software was used for statistical analyses of demographic characteristics, survival data, and Cox proportional hazards regression model. Standalone Internet gateway users demonstrated a more stable compliance pattern than did tablet device users. The compliance rate differed according to the device type. Typically, compliance decreases considerably around 8 months. In these results, standalone Internet gateway users utilized the service for longer periods than tablet device users. Gateway type and location also influenced utilization (p < 0.05). The service should be designed according to the device type to develop appropriate service models. Thus, service designers should understand the different characteristics of service devices. This study provides insight into compliance patterns and utilization to develop appropriate service models and service interventions depending on the device.

The prevalence of symptoms in HIV disease can be associated with HIV disease itself, comorbid illness, and/or antiretroviral therapy. Unhealthy substance use behaviors, particularly substance-use behaviors including heavy alcohol intake, marijuana use, other illicit drug use, and cigarette smoking, are engaged in by many HIV-positive individuals, often as a way to manage disease-related symptoms. This study is a secondary data analysis of baseline data from a larger randomized-controlled trial of an HIV/AIDS Symptom Management Manual. In the present study, the prevalence and characteristics of unhealthy substance use behaviors in relation to HIV/AIDS symptoms are examined. Subjects were recruited from a variety of settings which provide HIV/AIDS care and treatment. The mean age of the sample (n=775) was 42.8 years (SD=9.6) and nearly thirty-nine percent (38.5%) of the sample was female. The racial demographics of the sample were: 28% African American, 28% Hispanic, 21% White/Caucasian, 16% African from Kenya or South Africa, 1% Asian, and 5% self-described as “Other.” The mean number of years living with HIV was reported to be 9.1 years (SD=6.6).Specific self-reported unhealthy substance-use behaviors were use of marijuana (n= 111; 14.3%), cigarette smoking (n=355; 45.8%), heavy alcohol use (n= 66; 8.5%), and illicit drugs (n= 98; 12.6%). A subset of individuals who identified high levels of specific symptoms also reported significantly higher substance use behaviors including amphetamine and injection drug use in addition to heavy alcohol use, cigarette smoking, and marijuana use. Implications for clinical practice include assessment of self-care behaviors, screening for substance abuse, and education of persons related to self-management across the trajectory of HIV disease.

Web-based self-management support systems SMSS, can successfully assist a wide range of patients with information and self-management support. O or as a stand-alone service, are e-messages. This study describes how one component of a multi component SMSS, an e-message service, in which patients with breast cancer could direct questions to nurses, physicians or social workers at the hospital where they were being treated, had an influence on safety and continuity of care. Ninety-one dialogues consisting of 284 messages were analysed. The communications between patients and the healthcare team revealed that the e-messages service served as a means for quality assurance of information, for double-checking and for coordination of care. We give examples of how an e-mail service may improve patients' knowledge in a process of taking control over their own care - increasingly important in a time of growing complexity and specialization in healthcare. It remains to be tested whether an e-message service can improve continuity of care and prevent or mitigate medical mishaps.

Colorectal cancer screening rates for African American patients remain suboptimal. Patient decision aids designed with an entertainment-education approach have been shown to improve saliency and foster informed decision making. The purpose of this study was to assess whether an entertainment-education decision aid tailored for African American patients improved patients' decision making, attitudes, intentions, or colorectal cancer screening behavior. Eighty-nine participants were randomized to view 1) a patient decision aid video containing culturally tailored information about colorectal cancer screening options and theory-based support in decision making presented in an entertainment-education format or 2) an attention control video about hypertension that contained similarly detailed information. Participants met with their clinician and then completed follow-up questionnaires assessing their knowledge, decisional conflict, self-advocacy, attitudes, perceived social norms, and intentions. At 3 months, completion of screening was assessed by chart review. Viewing the culturally tailored decision aid significantly increased African American patients' knowledge of colorectal cancer screening recommendations and options. It also significantly reduced their decisional conflict and improved their self-advocacy. No significant differences were observed in participants' attitudes, norms, or intentions. At three months, 23% of all patients had completed a colonoscopy. Designing targeted, engaging patient decision aids for groups that receive suboptimal screening holds promise for improving patient decision making and self-advocacy. Additional research is warranted to investigate the effectiveness of such aids in clinical practices with suboptimal screening rates and on downstream behaviors (such as repeat testing).

Abstract Depressive symptoms are highly prevalent, underdiagnosed, and undertreated in people living with HIV/AIDS (PLWH), and are associated with poorer health outcomes. This randomized controlled trial examined the effects of the HIV/AIDS Symptom Management Manual self-care symptom management strategies compared with a nutrition manual on depressive symptoms in an international sample of PLWH. The sample consisted of a sub-group (N=222) of participants in a larger study symptom management study who reported depressive symptoms. Depressive symptoms of the intervention (n=124) and control (n=98) groups were compared over three months: baseline, one-month, and two-months. Use and effectiveness of specific strategies were examined. Depressive symptom frequency at baseline varied significantly by country (χ (2) 12.9; p=0.04). Within the intervention group there were significant differences across time in depressive symptom frequency [F(2, 207) = 3.27, p=0.05], intensity [F(2, 91) = 4.6, p=0.01], and impact [F(2, 252) = 2.92, p= 0.05), and these were significantly lower at one month but not at two months, suggesting that self-care strategies are effective in reducing depressive symptoms, however effects may be short term. Most used and most effective self-care strategies were distraction techniques and prayer. This study suggests that people living with HIV can be taught and will employ self-care strategies for management of depressive symptoms and that these strategies are effective in reducing these symptoms. Self-care strategies are noninvasive, have no side-effects, and can be readily taught as an adjunct to other forms of treatment. Studies are needed to identify the most effective self-care strategies and quantify optimum dose and frequency of use as a basis for evidence-based practice.

Advances in mobile technology provide an opportunity to deliver in-the-moment interventions to individuals with alcohol use disorders, yet availability of effective “apps” that deliver evidence-based interventions is scarce. We developed an immediately available, portable, smartphone-based intervention system whose purpose is to provide stand-alone, self-administered assessment and intervention. In this paper, we describe how theory and empirical evidence, combined with smartphone functionality contributed to the construction of a user-friendly, engaging alcohol intervention. With translation in mind, we discuss how we selected appropriate intervention components including assessments, feedback and tools, that work together to produce the hypothesized outcomes.

Predictors of Hearing-Aid Outcomes

2017-01-01

Over 360 million people worldwide suffer from disabling hearing loss. Most of them can be treated with hearing aids. Unfortunately, performance with hearing aids and the benefit obtained from using them vary widely across users. Here, we investigate the reasons for such variability. Sixty-eight hearing-aid users or candidates were fitted bilaterally with nonlinear hearing aids using standard procedures. Treatment outcome was assessed by measuring aided speech intelligibility in a time-reversed two-talker background and self-reported improvement in hearing ability. Statistical predictive models of these outcomes were obtained using linear combinations of 19 predictors, including demographic and audiological data, indicators of cochlear mechanical dysfunction and auditory temporal processing skills, hearing-aid settings, working memory capacity, and pretreatment self-perceived hearing ability. Aided intelligibility tended to be better for younger hearing-aid users with good unaided intelligibility in quiet and with good temporal processing abilities. Intelligibility tended to improve by increasing amplification for low-intensity sounds and by using more linear amplification for high-intensity sounds. Self-reported improvement in hearing ability was hard to predict but tended to be smaller for users with better working memory capacity. Indicators of cochlear mechanical dysfunction, alone or in combination with hearing settings, did not affect outcome predictions. The results may be useful for improving hearing aids and setting patients’ expectations. PMID:28929903

The factors associated with a self-perceived hearing handicap in elderly people with hearing impairment--results from a community-based study.

Elderly persons with a physiologic hearing deficit (hearing impairment) are not necessarily socially or emotionally disturbed by the deficit in everyday life (hearing handicap). The self-perception of a hearing handicap in elderly people is a key element in seeking consultation for a hearing impairment or using hearing aids. Thus, it is important to determine the factors associated with the self-perception of a hearing handicap. The aims of the present study were to report the relation between a hearing impairment and the self-perception of a hearing handicap, and the factors associated with a self-perceived hearing handicap among a group of randomly recruited, community-dwelling elderly persons, aged 65 yr and older, in Taipei, Taiwan. A cross-sectional survey of community-dwelling elderly persons aged 65 yr and older (N = 1220) participating in an annual general purpose geriatric health examination in 2005 in Taipei. Pure-tone audiometry and a questionnaire including the Hearing Handicap Inventory for the Elderly-Screening Version (HHIE-S) were administered, after obtaining the subject's consent to participate in the study. Demographic information, lifestyle, self-report health status, and biochemical data were also collected. There was a moderate association (gamma(s) = 0.52) between hearing impairment and self-perceived handicap. Only 21.4% of the study subjects with moderate to profound hearing impairment (M4 >or=41 dB HL, N = 555) perceived themselves as hearing-handicapped (HHIE-S total score >or=10). Besides hearing level, marital status (widowed) and self-perceived general health (bad or neutral) were factors that are significantly associated with a self-perceived hearing handicap among elderly subjects with moderate to profound hearing impairment. For study subjects with moderate to profound hearing impairment (M4 >or=41 dB HL), 5.0% of those with HHIE-S <10 and 45.4% of those with HHIE-S >or=10 used or felt that they required hearing aids (chi2 test, p < 0.001). These data suggested that a self-perceived hearing handicap (HHIE-S >or=10) is an important indicator for referral of elderly persons for hearing-aid fitting. Our study findings, consistent with those of previous studies, demonstrated that not all elderly persons with impaired hearing function (hearing impairment) perceived a hearing deficit socially or emotionally in everyday life (hearing handicap). Marital status (widowed) and bad/neutral general health were nonaudiologically associated factors with a hearing handicap in the present study. Further, those with a self-perceived hearing handicap reported a higher rate of the use of, or requirement for, hearing aids. Because hearing deterioration is a common biologic process of aging, the results of this study can be used to identify the groups among elderly people with a greater need for hearing screening and hearing rehabilitation services.

The study was aimed to measure incidence density rate and identify perceived behavioural believes of late initiation to HIV/AIDS care in Gurage zone public health facilities from September 2015 to November 2016. The incidence density rates of late initiation to HIV/AIDS care were 2.21 per 100 person-months of observation. HIV positive individuals who did not perceived susceptibility were 8.46 times more likely delay to start HIV/AIDS care than their counter parts [OR = 8.46 (95% CI 3.92, 18.26)]. HIV infected individuals who did not perceived severity of delayed ART initiation were 6.13 time more likely to delay than HIV infected individuals who perceived its severity [OR = 6.13 (95% CI 2.95, 12.73)]. HIV positive individuals who didn't have self-efficacy were 2.35 times more likely delay to start HIV/AIDS care than HIV positive individuals who have self-efficacy [OR = 2.35 (95% CI 1.09, 5.05)]. The study revealed that high incidence density rates of delayed initiation for HIV care and variations were explained by poor wealth, and perceived threat and benefit. Therefore, interventions should be designed to initiate care at their diagnosis time.

To identify the effectiveness of rational-emotive-behavior-based therapy (REBT-based therapy) on improved mental health and antiretroviral (ART) therapeutic adherence in women infected with HIV/AIDS (female subjects with HIV/AIDS). A randomized and single-blinded clinical trial in women infected with HIV/AIDS who had their treatment at the outpatient clinic of Pokdiksus AIDS RSCM and at the AIDS Comprehensive Diagnostic Unit of Dharmais Hospital was conducted between October 2011 and March 2012. A block randomization of 160 female subjects with AIDS was performed that resulted in a REBT-based treatment group (n=80) and a control group (n=80). The treatment group received REBT-based intervention of 8 sessions weekly including 6 individual-therapeutic sessions/week and 2 group-therapeutic sessions/week. Instruments used in the study were questionnaires on demography, ART adherence (measured by self report and pill count), and mental health (SRQ-20). Data were analyzed using Chi-Square test, Generalized Linear Model, and Generalized Estimating Equations. There were 148 respondents analyzed including in the REBT-based group (n=72) and in the control group (n=76) with mean age of 33-34 years. After 8 weeks of REBT-based intervention, there was improved (increased) mean value of the self-reported adherence score (self-report) compared to control group (100%; CI 95%,83.3-96.7 vs. 84%; CI 95%,77.5-87.8) and improved (decreased) SRQ-20 mean score in REBT-based treatment group compared to control group (2.9; CI 95%, 2.7-13.0 vs. 5.4; CI 95%: 5.0-13.6). ART adherence based on viral load titer was not analyzed in both group since most of VL titer were undetected (<400 copies/mL). GLM analysis showed decreased SRQ-20 mean score and increased mean value of self-reported ART adherence (self-report) in the REBT-based treatment group, which were more significant (p<0.000) than control group on the 8th week. GEE analysis showed that 1 point decrement of SRQ-20 would increase self-reported ART adherence as much as 0.722 point and the correlation was statistically significant (p<0.00). After 8 weeks of REBT-based intervention to female subjects with HIV/AIDS, there is a decrease of SRQ-20 mean score which may result in increased ART adherence mean score in the treatment group compared to the control.

Medical device regulations which aim to ensure safety standards do not only apply to hardware devices but also to standalone medical software, e.g. mobile apps. To explore the effects of these regulations on the development and distribution of medical standalone software. We invited a convenience sample of 130 domain experts to participate in an online survey about the impact of current regulations on the development and distribution of medical standalone software. 21 respondents completed the questionnaire. Participants reported slight positive effects on usability, reliability, and data security of their products, whereas the ability to modify already deployed software and customization by end users were negatively impacted. The additional time and costs needed to go through the regulatory process were perceived as the greatest obstacles in developing and distributing medical software. Further research is needed to compare positive effects on software quality with negative impacts on market access and innovation. Strategies for avoiding over-regulation while still ensuring safety standards need to be devised.

An Overview of a Trajectory-Based Solution for En Route and Terminal Area Self-Spacing: Seventh Revision

2015-01-01

This paper presents an overview of the seventh revision to an algorithm specifically designed to support NASA's Airborne Precision Spacing concept. This paper supersedes the previous documentation and presents a modification to the algorithm referred to as the Airborne Spacing for Terminal Arrival Routes version 13 (ASTAR13). This airborne self-spacing concept contains both trajectory-based and state-based mechanisms for calculating the speeds required to achieve or maintain a precise spacing interval. The trajectory-based capability allows for spacing operations prior to the aircraft being on a common path. This algorithm was also designed specifically to support a standalone, non-integrated implementation in the spacing aircraft. This current revision to the algorithm adds the state-based capability in support of evolving industry standards relating to airborne self-spacing.

This paper presents an overview of the eighth revision to an algorithm specifically designed to support NASA's Airborne Precision Spacing concept. This paper supersedes the previous documentation and presents a modification to the algorithm referred to as the Airborne Spacing for Terminal Arrival Routes version 13 (ASTAR13). This airborne self-spacing concept contains both trajectory-based and state-based mechanisms for calculating the speeds required to achieve or maintain a precise spacing interval with another aircraft. The trajectory-based capability allows for spacing operations prior to the aircraft being on a common path. This algorithm was also designed specifically to support a standalone, non-integrated implementation in the spacing aircraft. This current revision to the algorithm supports the evolving industry standards relating to airborne self-spacing.

Physical activity (PA) can reduce cigarette cravings and aid quitting but little is known about its promotion by smoking cessation advisors. This study aimed to: (1) determine the extent to which smoking cessation advisors promote PA; and (2) examine the relationship between PA promotion as a cessation aid and advisor characteristics and cognitions, within the Transtheoretical Model (TM) framework. Self-report surveys assessing PA promotion, TM variables, advisors' own PA levels and demographics were completed by 170 advisors in England and Scotland. Advisors reported spending 29min promoting PA over a 6/7-week clinic. Those in later stages of readiness for promoting PA as a cessation aid and those spending more time promoting PA held more positive beliefs regarding pros and cons, self-efficacy, outcome efficacy and importance of PA within smoking cessation. Time spent promoting PA and stage of readiness were strongly associated. There was a trend for the more physically active advisors to promote PA more often. About half the advisors promoted PA and TM variables predicted this variability. PA promotion among smoking cessation advisors may be facilitated by enhancing self-efficacy, outcome efficacy and pro- and con-beliefs related to PA promotion.

Self-monitoring Lifestyle Behavior in Overweight and Obese Pregnant Women: Qualitative Findings.

PubMed

Shieh, Carol; Draucker, Claire Burke

Excessive maternal gestational weight gain increases pregnancy and infant complications. Self-monitoring has been shown to be an effective strategy in weight management. Literature, however, is limited in describing pregnant women's engagement in self-monitoring. This qualitative study explored the experiences of overweight and obese pregnant women who self-monitored their eating, walking, and weight as participants in an intervention for excessive gestational weight gain prevention. Thirteen overweight and obese pregnant women participated in semistructured interviews. Reflexive iteration data analysis was conducted. Five themes were identified: making self-monitoring a habit, strategies for self-monitoring, barriers to self-monitoring, benefits of self-monitoring, and drawbacks of self-monitoring. The women viewed self-monitoring as a "habit" that could foster a sense of self-control and mindfulness. Visual or tracing aids were used to maintain the self-monitoring habit. Forgetting, defective tracking aids, complexities of food monitoring, and life events could impede self-monitoring. Being unable to keep up with self-monitoring or to achieve goals created stress. Self-monitoring is a promising approach to weight management for overweight and obese pregnant women. However, healthcare providers should be aware that, although women may identify several benefits to self-monitoring, for some women, consistently trying to track their behaviors is stressful.

Parental deaths due to AIDS seriously affect the psychological well-being of children. Social support may provide an effective resource in the care of vulnerable children in resource-limited settings. However, few studies have examined the relationships between social support and psychological well-being among AIDS orphans. This cross-sectional study was conducted to explore associations between perceived social support (PSS) and the psychological well-being of AIDS orphans, and to identify socio-demographic factors that are associated with PSS. Data were collected from 398 pairs of AIDS orphans (aged 10-18 years) and their caregivers in Nairobi, Kenya. The participants provided information on their socio-demographic characteristics, the children's PSS, and the children's psychological status (based on measures of depressive symptoms and self-esteem). Of the 398 pairs, 327 were included in the analysis. PSS scores of AIDS orphans showed significant correlations with depressive symptoms (ρ =-0.31, p<0.001) and self-esteem (ρ=0.32, p<0.001). Socio-demographic factors, such as HIV-positive status of children (β=3.714, p=0.014) and cohabitation with siblings (β=3.044, p=0.016), were also associated with higher PSS scores. In particular, HIV-infected children (n=37) had higher scores of PSS from a special person (β=2.208, p=0.004), and children living with biological siblings (n=269) also had higher scores of PSS from both a special person (β=1.411, p=0.029) and friends (β=1.276, p=0.039). In conclusion, this study showed that PSS is positively associated with the psychological well-being of AIDS orphans. Siblings and special persons can be effective sources of social support for AIDS orphans, which help to promote their psychological well-being.

The purpose of this study was to determine the effects of sequential versus simultaneous bilateral hearing aids fitting on patient compliance. Thirty-six older adults with hearing impairment participated in this study. Twelve were fitted with bilateral hearing aids simultaneously. The remaining participants were fitted sequentially: One hearing aid (to the left or to the right ear) was used initially; 1 month later, the other ear was also fitted with a hearing aid for bilateral use. Self-reports on usefulness and compliance were elicited after the first and second months of hearing aid use. In addition, the number of hours the hearing aids were used was extracted from the data loggings of each device. Simultaneous fitting resulted in high levels of compliance and consistent usage throughout the study period. Sequential fitting resulted in abrupt reduction in compliance and hours of use once the second hearing aid was added, both in the clinical scoring and in the data loggings. Simultaneous fitting of bilateral hearing aids results in better compliance compared with sequential fitting. The addition of a second hearing aid after a relatively short period of monaural use may lead to inconsistent use of both hearing aids.

HIV/AIDS is an important public health issue in China. The number of people living with HIV/AIDS (PLWHA) has been increasing since the introduction of highly active antiretroviral therapy. PLWHA's life quality is becoming an important issue, with lack of research in China. In this study, a group of PLWHA (n = 663) was identified using HIV/AIDS relevant usernames on a Chinese social networking site (Weibo) to study their daily living situations. We found that more than 99.10% of PLWHA were male, among whom 90.80% turned out to be homosexual. They had significantly more fans and followees, but fewer postings compared to the general population. The mean age of the PLWHA was 28.96 (SD = 5.05) years old, and southwest and northwest China had a high prevalence of HIV/AIDS. In addition, PLWHA's postings were coded and we found that more than half of the postings (n = 769, 51.03%) contained strong emotions. Less than one-fifth of the postings were directly related to HIV/AIDS topics (n = 269, 17.85%), while seeking emotional support, such as looking for stable partnership, was ranked as the first priority of support seeking. In summary, we found that the majority of the self-labeled PLWHA were likely to be men who have sex with men. They used Weibo to share their daily life events and seek emotional support. Implications for promoting HIV/AIDS education and prevention through Chinese social networking sites were also discussed.

Objective: To investigate the features and influencing factors of self-discrimination among patients with HIV/AIDS according to sex. Methods: A total of 2 432 HIV/AIDS patients were recruited in Yunnan, Henan, Hubei, Jiangsu, Shanxi, Jilin, and Inner Mongolia provinces by a multistage stratified cluster sampling method, based on HIV epidemic and transmission modes, from May 2013 to October 2013. All participants were ≥18 years old, and we excluded those with mental disorders, hearing loss or other factors that prevented them from properly answering questions, and those who were unwilling to participate. A self-designed questionnaire was conducted to collect information about self-discrimination features and social behavior changes among HIV/AIDS patients. Differences in performance and self-discrimination features between participants of different sexes were compared using the chi-squared test. Factors influencing self-discrimination were analyzed by sex, using unconditional logistic regression. Results: Of the 2 432 cases, 78.9%(1 918 cases)were male and 21.1%(514 cases)female. The proportion of self-discrimination overall was 76.1%(1 850 cases); this proportion among female HIV/AIDS patients was 80.5%(414 cases), which was higher than that among men(74.9%, 1 436 cases)(χ 2 =7.17, P= 0.007). Of the 11 forms of self-discrimination performance, proportions of feeling guilt, shame, and self-abasement among participants were greater than 50%. Proportions of feeling shame, inferiority, and blaming others among females were 61.3%, 59.5%, and 45.3%, respectively, which were higher than these among males(49.8%, 50.0%, 28.4%, respectively)( P< 0.01). Multivariate unconditional logistic regression analysis showed that the risk of self-discrimination among those with HIV confirmatory testing time ≥1 year was higher than those with HIV confirmatory testing time <1 year(females: OR= 35.67, 95 %CI :17.28-73.64; males: OR= 8.74, 95 % CI :6.79-11.25). Compared with other occupations, the risk of self-discrimination among male farm workers was higher( OR= 1.62, 95 % CI :1.03-2.54). The risks of self-discrimination in males who had been infected with HIV by transmission routes of blood transfusion or blood collection( OR= 2.38, 95 % CI :1.31-4.30), injection drug use( OR= 1.78, 95 % CI :1.09-2.91), and male-to-male sexual behavior( OR= 1.48, 95 %CI :1.08-2.03)were higher than in males infected via heterosexual behavior. Conclusion: Female HIV/AIDS patients are more likely to engage in self-discrimination than male patients. Self-discrimination mainly takes the form of feeling remorse, shame, and inferiority. Confirmatory testing time ≥1 year, occupation as a farm work, and routes of transmission via blood transfusion or collection, injection drug use, and male-to-male sexual behavior are influencing factors of self-discrimination among male HIV/AIDS patients. Confirmatory testing time ≥1 year is the influencing factor of self-discrimination among female HIV/AIDS patients.

This study examined the relative efficacy of social support seeking (SSS) and self-efficacy building (SEB) in the management of emotional well-being of caregivers of people suffering from HIV/AIDS. It was based at the United States President's Emergency Plan for AIDS Relief (PEPFAR) center in the University College Hospital, Ibadan, Oyo state, being the first and the largest teaching hospital in Nigeria. A 3 × 2 factorial design consisting of treatment and a control group was used. The columns have two levels of gender being male and female caregivers. One-hundred and sixty-five (165) caregivers who were taking care of people that are suffering from HIV/AIDS were purposively selected and randomly assigned to the treatment groups and control. The treatment was carried out for a period of eight weeks. Two null hypotheses were tested, both at .05 levels of significance. Data were collected with the use of standardized intruments rating scale; social support scale, general self-efficacy scale and emotional well-being scale. ANCOVA was used to establish significant treatment effects with the pretest as covariate. Even though SSS and SEB were both found to be effective in enhancing the emotional well-being of informal caregivers in this study when compared to the controls, SSS was significantly more effective than SEB in achieving this goal. Since the HIV/AIDS patients cannot be adequately cared for in the hospital settings due to severe shortages of material, personnel and time, serious efforts should be made by the three levels of the health care system viz: the primary, secondary and tertiary health care systems, to encourage the employment of the psychological management of caregivers of people suffering from HIV/AIDS. Also, the psychologists, clinical psychologists and the significant others should be encouraged to employ this psychological management in the care of HIV/AIDS informal caregivers.

Aims To describe the relationships among home-based physical activity, fatigue, sleep, gender and quality of life in people living with HIV/AIDS Background Fatigue is a common and distressing symptom among people living with HIV/AIDS. Few interventions exist that effectively reduce fatigue in this population. Physical activity has shown promise to reduce fatigue in other populations, but its impact on fatigue in HIV/AIDS has not yet been explored. Design This study was conducted using a prospective, descriptive cohort design. Methods Overall, 90 adults living with HIV/AIDS completed cross-sectional measures. Home-based physical activity was measured using a seven-day self-report diary. Fatigue was measured using the self-reported HIV-Related Fatigue Scale. Sleep was assessed using wrist actigraphy and quality of life was assessed using the HIV-Associated Quality of Life Scale. Data were collected from December 2012 – April 2013 and analyzed using correlations and multiple linear regression. Results The number of minutes of home-based physical activity was significantly associated with reduced fatigue among people living with HIV/AIDS. Additionally, increased fatigue was associated with decreased quality of life. No associations were found among fatigue, sleep or gender. Conclusions Our study demonstrates that physical activity in the home setting is an effective strategy to reduce fatigue among people living with HIV/AIDS. Future work developing and testing interventions to improve home-based physical activity in this population is needed. PMID:27485463

The prevalence of lipodystrophy ranges from 31 to 65%, depending on the criteria adopted for diagnosis. The usual methods applied in the diagnosis vary from self-perception, medical examination, skinfolds measurements, or even imaging assessment for confirmation of fat distribution changes. Although several methods have been developed, there is no gold standard for characterization of LA and LH, or mixed forms. This study aimed to compare self-reported signs of lipodystrophy with objective measures by skinfolds and circumferences, and to evaluate the prevalence of lipoatrophy (LA) and lipohypertrophy (LH) among subjects living with HIV/AIDS on ART. A cross-sectional study enrolled participants living with HIV/AIDS receiving ART, aged 18 years or older from an outpatient health care center, in Southern Brazil. Self-reported body fat enlargement in the abdomen, chest or breasts, and dorsocervical fat pad were used to determine LH, while LA was identified by self-reported fat wasting of the face, neck, legs, arms or buttocks. Measurements were obtained with a scientific caliper for infraorbital, buccal, and submandibular skinfolds, and using an inelastic tape to measure circumferences of waist, hip, neck, and arm. LH and LA were established by the presence of at least one self-reported sign. Comparisons of self-reported signs with objective measurements for men and women were carried out in 815 participants on ART, out of 1240 participants with HIV infection. Self-report of decreased facial fat and sunken cheeks was associated with lower infraorbital, buccal, and submandibular skinfolds. Participants who reported buffalo hump had, on average, greater neck circumference, as well as those who have increased waist circumference also reported abdominal enlargement, but no buttock wasting. Men were most commonly affected by lipoatrophy (73 vs. 53%; P < 0.001), and women by lipohypertrophy (79 vs. 56%; P < 0.001). In conclusion, self-reported signs of lipodystrophy and lipoatrophy are prevalent, differ by gender, and are associated with objective measurements in people living with HIV/AIDS.

2017-09-01

In this research, an indoor map aided INS/Wi-Fi integrated location based services (LBS) applications is proposed and implemented on smartphone platforms. Indoor map information together with measurements from an inertial measurement unit (IMU) and Received Signal Strength Indicator (RSSI) value from Wi-Fi are collected to obtain an accurate, continuous, and low-cost position solution. The main challenge of this research is to make effective use of various measurements that complement each other without increasing the computational burden of the system. The integrated system in this paper includes three modules: INS, Wi-Fi (if signal available) and indoor maps. A cascade structure Particle/Kalman filter framework is applied to combine the different modules. Firstly, INS position and Wi-Fi fingerprint position integrated through Kalman filter for estimating positioning information. Then, indoor map information is applied to correct the error of INS/Wi-Fi estimated position through particle filter. Indoor tests show that the proposed method can effectively reduce the accumulation positioning errors of stand-alone INS systems, and provide stable, continuous and reliable indoor location service.

Microfluidic systems enable rapid diagnosis, screening and monitoring of diseases and health conditions using small amounts of biological samples and reagents. Despite these remarkable features, conventional microfluidic systems rely on bulky expensive external equipment, which hinders their utility as powerful analysis tools outside of research laboratories. 'Self-contained' microfluidic systems, which contain all necessary components to facilitate a complete assay, have been developed to address this limitation. In this review, we provide an in-depth overview of self-contained microfluidic systems. We categorise these systems based on their operating mechanisms into three major groups: passive, hand-powered and active. Several examples are provided to discuss the structure, capabilities and shortcomings of each group. In particular, we discuss the self-contained microfluidic systems enabled by active mechanisms, due to their unique capability for running multi-step and highly controllable diagnostic assays. Integration of self-contained microfluidic systems with the image acquisition and processing capabilities of smartphones, especially those equipped with accessory optical components, enables highly sensitive and quantitative assays, which are discussed. Finally, the future trends and possible solutions to expand the versatility of self-contained, stand-alone microfluidic platforms are outlined.

Alghazo, Jaafar M

2017-02-01

The goal of this paper is to implement the secretion mechanism of the Thyroid Hormone (TH) based on bio-mathematical differential eqs. (DE) on an FPGA chip. Hardware Descriptive Language (HDL) is used to develop a behavioral model of the mechanism derived from the DE. The Thyroid Hormone secretion mechanism is simulated with the interaction of the related stimulating and inhibiting hormones. Synthesis of the simulation is done with the aid of CAD tools and downloaded on a Field Programmable Gate Arrays (FPGAs) Chip. The chip output shows identical behavior to that of the designed algorithm through simulation. It is concluded that the chip mimics the Thyroid Hormone secretion mechanism. The chip, operating in real-time, is computer-independent stand-alone system.

A 1-kW preprototype redox storage system that has undergone characterization tests and been operated as the storage device for a 5-kW (peak) photovoltaic array is described and performance data are presented. Loss mechanisms are discussed, and simple design changes leading to appreciable increases in efficiency are suggested. The effects on system performance of nonequilibrium between the predominant species of complexed chromic ion in the negative electrode reactant solution are summarized. It is noted that with the aid of the prototype system, control concepts have been shown to be valid and trouble free and some insight has been gained into interactions at the mutual interfaces of the redox system, the photovoltaic array, the load, and the control devices.

Outcomes With a Self-Fitting Hearing Aid.

Keidser, Gitte; Convery, Elizabeth

2018-01-01

Self-fitting hearing aids (SFHAs)-devices that enable self-directed threshold measurements leading to a prescribed hearing aid (HA) setting, and fine-tuning, without the need for professional support-are now commercially available. This study examined outcomes obtained with one commercial SFHA, the Companion (SoundWorld Solutions), when support was available from a clinical assistant during self-fitting. Participants consisted of 27 experienced and 25 new HA users who completed the self-fitting process, resulting in 38 user-driven and 14 clinician-driven fittings. Following 12 weeks' experience with the SFHAs in the field, outcomes measured included the following: coupler gain and output, HA handling and management skills, speech recognition in noise, and self-reported benefit and satisfaction. In addition, the conventionally fitted HAs of 22 of the experienced participants who had user-driven fittings were evaluated. Irrespective of HA experience, the type of fitting (user- or clinician-driven) had no significant effect on coupler gain, speech recognition scores, or self-reported benefit and satisfaction. Users selected significantly higher low-frequency gain in the SFHAs when compared with the conventionally fitted HAs. The conventionally fitted HAs were rated significantly higher for benefit and satisfaction on some subscales due to negative issues with the physical design and implementation of the SFHAs, rather than who drove the fitting process. Poorer cognitive function was associated with poorer handling and management of the SFHAs. Findings suggest that with the right design and support, SFHAs may be a viable option to improve the accessibility of hearing health care.

This study aimed to assess toothbrushing behavior and descriptively analyze the effect of age and gender. Two thousand and six people from the city of Sebha, Libya, aged 1 to 64 years (mean age 26.9 ± 11.6 years, 1,463 females and 543 males) constituted the study sample. Data was collected using a self-administered questionnaire. Overall, 85.3% were using a toothbrush and toothpaste as a cleaning aid, whereas 6.3% never brushed their teeth. Only 36.1% brushed twice daily. Age and gender were significantly associated with use of a toothbrush and frequency of toothbrushing. This data serves as a baseline to implement a "preventive self-care instruction program."

MEDIATORS OF THE RELATIONSHIP BETWEEN NICOTINE REPLACEMENT THERAPY AND SMOKING ABSTINENCE AMONG PEOPLE LIVING WITH HIV/AIDS

Cigarette smoking is highly prevalent among people living with HIV/AIDS and poses unique health risks. Smoking cessation programs tailored to this population have documented improved smoking outcomes with nicotine replacement therapy (NRT). The current study examined 6-month abstinence rates from a randomized clinical trial targeting 412 HIV-positive adult current smokers (51% European American, 19% African American, and 17% Hispanic American) and tested whether psychosocial variables, such as self-efficacy and decisional balance, mediated the relationship between NRT and long-term abstinence. Meeting criteria for complete mediation, 6-month smoking abstinence rates improved significantly with increases in these mediators, and the association of NRT and smoking abstinence was no longer significant once changes in self-efficacy and decisional balance were taken into account. Failure to translate gains in self-efficacy among African Americans into improved abstinence rates accounted for racial/ ethnic differences among participants. Specific psychosocial factors, such as self-efficacy, may be particularly amenable to change in cessation interventions and should be addressed with greater awareness of how cultural and social contextual factors impact treatment response among people living with HIV/AIDS.

In Mozambique, women are the most affected by HIV/AIDS. Self-efficacy is one of the main predictors of effective use of a condom. Therefore, it is essential to identify the factors that influence condom-use negotiation self-efficacy in vulnerable women. The aim of this paper is to identify socio-demographic, marital, and psychosocial factors associated with condom-use negotiation self-efficacy among Mozambican women at risk for HIV infection. Participants were women (173) who were patients at the Gynecology Department of the Central Hospital of Beira, Mozambique, and at risk for HIV infection. Women completed measures of condom-use negotiation self-efficacy, HIV prevention knowledge, and perceived barriers against safer sex. The results showed that demographic and marital variables are associated with condom-use negotiation self-efficacy, namely, those having more than 9 years of education, who are younger and not living with a partner, and who talk about AIDS with partners report higher condom-use negotiation self-efficacy. Regarding psychosocial factors, higher HIV prevention knowledge and fewer perceived barriers to safer sex predict higher condom-use negotiation self-efficacy. These results can contribute to sexual health promotion and HIV/AIDS prevention in Mozambican women because they identify at-risk groups and marital and psychosocial malleable factors that can be targeted in AIDS prevention among at-risk Mozambican women.

Assessment of HIV/AIDS knowledge, attitudes and behaviours among students in higher education in Tanzania.

PubMed

Mkumbo, Kitila

2013-01-01

There is a paucity of studies that have systematically and comprehensively investigated the knowledge level, attitudes and the pattern of sexual behaviours related to HIV and AIDS in higher education settings in sub-Saharan Africa in general and Tanzania in particular. This study attempted to fill a void in knowledge. A cross-sectional descriptive design was used, employing a self-administered questionnaire as the main data collection tool. More than 400 higher education students completed a questionnaire assessing their knowledge, attitudes and behaviours related to HIV and AIDS. About three quarters of respondents demonstrated comprehensive knowledge about HIV and AIDS, and the majority of respondents expressed positive attitudes towards people living with HIV and AIDS. Despite demonstrating high knowledge level about HIV and AIDS, the results show that sexual behaviours among students in higher education are characteristically risky, and do not significantly differ from youth in the general population.

Postnatal Unit Bassinet Types When Rooming-In After Cesarean Birth: Implications for Breastfeeding and Infant Safety

PubMed Central

Tully, Kristin P.; Ball, Helen L.

2013-01-01

Background Postnatal unit rooming-in promotes breastfeeding. Previous research indicates that side-cars (three-sided bassinets that lock onto the maternal bed-frame) faciliate breastfeeding after vaginal birth more than stand-alone bassinets (standard rooming-in). No study has previously investigated side-car bassinet use after cesarean, despite the constraints on maternal-infant interactions that are inherent in recovery from this birth mode. Objective To test the effect of the side-car bassinet on postnatal unit breastfeeding frequency and other maternal-infant behaviors compared to a stand-alone bassinet following cesarean birth. Methods Participants were recruited and prenatally randomized to receive the side-car or stand-alone bassinet for their postnatal unit stay between January 2007 and March 2009 in Northeast England. Mother-infant interactions were filmed over the second postpartum night. Participants completed face-to-face interviews before and after filming. The main outcome measures were infant location, bassinet acceptability, and breastfeeding frequency. Other outcomes assessed were breastfeeding effort, maternal-infant contact, sleep states, midwife presence, and infant risk. Results Differences in breastfeeding frequency, maternal-infant sleep overlap, and midwife presence were not statistically significant. The 20 dyads allocated to side-car bassinets breastfed a median of 0.6 bouts/ hour compared to 0.4 bouts/hour for the 15 stand-alone bassinet dyads. Participants expressed overwhelming preference for the side-car bassinets. Bedsharing was equivalent between the groups, although the motivation for this practice may have differed. Infant handling was compromised with stand-alone bassinet use, including infants positioned on pillows while bedsharing with their sleeping mothers. Conclusions Women preferred the side-car but differences in breastfeeding frequency were not significant. More infant risks were observed with stand-alone bassinet use. PMID:22914755

Fear appeals threatening the individual have been shown to be powerful persuasive devices in the cultures where they have been studied. However, most fear appeal research has been conducted with members of individualist cultures. Individualist cultures place self-needs above group concerns, while collectivist cultures place group needs above self-concerns. Little is known about the effectiveness of fear appeals (or other persuasive strategies) in collectivist cultures. Two studies assessed the effectiveness of AIDS-prevention fear appeals threatening the self versus fear appeals threatening the group (i.e., family) on members of individualist and collectivist cultures. The first study focuses on African American and Mexican immigrant junior high school youth. The second study focuses on U.S. and Taiwanese college undergraduates. The results indicated that fear appeals should address cultural orientation (i.e., individualist versus collectivist orientation) to achieve maximum effectiveness. The results also indicate that one cannot assume cultural orientation based on ethnicity.

Pain in amaXhosa women living with HIV/AIDS: a cross-sectional study of ambulant outpatients.

Parker, Romy; Jelsma, Jennifer; Stein, Dan J

2017-04-13

Pain is one of the most commonly reported symptoms in people living with HIV/AIDS, whether or not they are receiving anti-retroviral therapy. A recent systematic review identified a paucity of studies exploring pain in women in low and middle income countries. The prevalence and characteristics of pain in women living with HIV/AIDS may differ from that of men as many chronic pain conditions are more prevalent in women. The aims of this study were to establish pain prevalence, characteristics and management in amaXhosa women living with HIV/AIDS. In addition, we aimed to identify whether there were associations between pain in this population and the psychosocial factors of employment, education, self-efficacy, depression, post-traumatic stress disorder, health related quality of life and childhood trauma. A cross-sectional study of 229 women who had undergone HIV testing and were registered patients at a community health centre was conducted. Data were collected by interview with a demographic questionnaire, the Brief Pain Inventory-Xhosa, Childhood Trauma Questionnaire-Xhosa, Harvard Trauma Questionnaire-Xhosa for PTSD, Self-Efficacy for Managing Chronic Disease 6-Item Scale-Xhosa; the EQ-5D health related quality of life instrument, and the Beck Depression Inventory. 170 of the women had pain, a prevalence rate of 74.24% (95%CI 68.2 - 79.47%). The women reported significant pain with pain severity of 5.06 ± 1.57 and pain interference of 6.39 ± 1.96 out of 10. Only two women were receiving adequate pain management according to the pain management index. Participants reported a mean of 2.42 ± 1.21 different anatomical sites of pain. There were more unemployed participants in the group with pain and they had significantly fewer years of schooling. Those with pain had lower self-efficacy; health related quality of life and increased depression and PTSD symptom severity. This study highlights that pain is a common problem for amaXhosa women living with HIV/AIDS. These data emphasise the need to prioritise pain assessment and management in amaXhosa women living with HIV/AIDS. Routinely assessing for the presence of pain in women with HIV/AIDS has the potential to improve pain management and minimise the impact of pain on function.

Visual aided pacing in respiratory maneuvers

A visual aid to pace self-controlled respiratory cycles in humans is presented. Respiratory manoeuvres need to be accomplished in several clinic and research procedures, among others, the studies on Heart Rate Variability. Free running respiration turns to be difficult to correlate with other physiologic variables. Because of this fact, voluntary self-control is asked from the individuals under study. Currently, an acoustic metronome is used to pace respiratory frequency, its main limitation being the impossibility to induce predetermined timing in the stages within the respiratory cycle. In the present work, visual driven self-control was provided, with separate timing for the four stages of a normal respiratory cycle. This visual metronome (ViMet) was based on a microcontroller which power-ON and -OFF an eight-LED bar, in a four-stage respiratory cycle time series handset by the operator. The precise timing is also exhibited on an alphanumeric display.

Computer-aided vs. tutor-delivered teaching of exposure therapy for phobia/panic: randomized controlled trial with pre-registration nursing students.

PubMed

Gega, L; Norman, I J; Marks, I M

2007-03-01

Exposure therapy is effective for phobic anxiety disorders (specific phobias, agoraphobia, social phobia) and panic disorder. Despite their high prevalence in the community, sufferers often get no treatment or if they do, it is usually after a long delay. This is largely due to the scarcity of healthcare professionals trained in exposure therapy, which is due, in part, to the high cost of training. Traditional teaching methods employed are labour intensive, being based mainly on role-play in small groups with feedback and coaching from experienced trainers. In an attempt to increase knowledge and skills in exposure therapy, there is now some interest in providing relevant teaching as part of pre-registration nurse education. Computers have been developed to teach terminology and simulate clinical scenarios for health professionals, and offer a potentially cost effective alternative to traditional teaching methods. To test whether student nurses would learn about exposure therapy for phobia/panic as well by computer-aided self-instruction as by face-to-face teaching, and to compare the individual and combined effects of two educational methods, traditional face-to-face teaching comprising a presentation with discussion and questions/answers by a specialist cognitive behaviour nurse therapist, and a computer-aided self-instructional programme based on a self-help programme for patients with phobia/panic called FearFighter, on students' knowledge, skills and satisfaction. Randomised controlled trial, with a crossover, completed in 2 consecutive days over a period of 4h per day. Ninety-two mental health pre-registration nursing students, of mixed gender, age and ethnic origin, with no previous training in cognitive behaviour therapy studying at one UK university. The two teaching methods led to similar improvements in knowledge and skills, and to similar satisfaction, when used alone. Using them in tandem conferred no added benefit. Computer-aided self-instruction was more efficient as it saved teacher preparation and delivery time, and needed no specialist tutor. Computer-aided self-instruction saved almost all preparation time and delivery effort for the expert teacher. When added to past results in medical students, the present results in nurses justify the use of computer-aided self-instruction for learning about exposure therapy and phobia/panic and of research into its value for other areas of health education.

Stigma is commonly experienced by people living with HIV/AIDS and by those providing care to HIV/AIDS patients. Few intervention studies have explored the impact of workplace policies and/or quality improvement on stigma. We examine the contribution of health care workplace policies, procedures and quality assurance initiatives, and self- and peer-assessed individual nurse practices, to nurse-reported HIV/AIDS-stigma practices toward patients living with HIV/AIDS and nurses in health care settings. Our sample of survey respondents (n = 1157) included managers (n = 392) and registered/enrolled nurses (n = 765) from 29 facilities in 4 countries (South Africa, Uganda, Jamaica, Kenya). This is one of the first studies in LMIC countries to use hierarchical linear modeling to examine the contributions of organizational and individual factors to HIV/AIDS stigma. Based on our results, we argue that organizational interventions explicitly targeting HIV/AIDS stigma are required to reduce the incidence, prevalence and morbidity of HIV/AIDS.

1998-10-01

Self-transcendence has been shown to be related to well-being in older adults, women with breast cancer, women with AIDS, gay men with AIDS, and a healthy population. The purpose of this descriptive pilot study was to examine self-transcendence in another high-priority population: older men with prostate cancer. A convenience sample of 23 men, age 60 and older (M = 69), from three prostate cancer support groups completed Reed's Self-Transcendence Scale (STS) and a demographic data form. The men were predominantly white (82.6%), of the Catholic faith (56.5%), married (78.3%), and not working (87.0%). Over half (65.2%) had a college degree or higher; most viewed their health as good (69.6%) or excellent (21.7%); and the majority (56.5%) viewed their prostate cancer as affecting some of their daily activities. These men scored high on the STS (M = 50.07), which was consistent with previous findings in other populations. Findings of this study contribute to Reed's middle-range theory of self-transcendence. The discovery that self-transcendence is relevant to this group of older men with prostate cancer provides a basis for nurses to investigate the phenomenon in this population and help their clients explore the benefits of the self-transcendence resource.

Usher syndrome is the leading cause of hereditary deaf-blindness. Most patients with Usher syndrome type IIa start using hearing aids from a young age. A serious complaint refers to interference between sound localisation abilities and adaptive sound processing (compression), as present in today's hearing aids. The aim of this study was to investigate the effect of advanced signal processing on binaural hearing, including sound localisation. In this prospective study, patients were fitted with hearing aids with a nonlinear (compression) and linear amplification programs. Data logging was used to objectively evaluate the use of either program. Performance was evaluated with a speech-in-noise test, a sound localisation test and two questionnaires focussing on self-reported benefit. Data logging confirmed that the reported use of hearing aids was high. The linear program was used significantly more often (average use: 77%) than the nonlinear program (average use: 17%). The results for speech intelligibility in noise and sound localisation did not show a significant difference between type of amplification. However, the self-reported outcomes showed higher scores on 'ease of communication' and overall benefit, and significant lower scores on disability for the new hearing aids when compared to their previous hearing aids with compression amplification. Patients with Usher syndrome type IIa prefer a linear amplification over nonlinear amplification when fitted with novel hearing aids. Apart from a significantly higher logged use, no difference in speech in noise and sound localisation was observed between linear and nonlinear amplification with the currently used tests. Further research is needed to evaluate the reasons behind the preference for the linear settings. © 2016 The Authors. Clinical Otolaryngology Published by John Wiley & Sons Ltd.

“We, the AIDS people. . .”: How Antiretroviral Therapy Enables Zimbabweans Living With HIV/AIDS to Cope With Stigma

2011-01-01

We studied the impact of antiretroviral treatment availability on HIV/AIDS stigma through interviews with 118 antiretroviral treatment users, HIV/AIDS caregivers, and nurses in Zimbabwe. Treatment enables positive social and economic participation through which users can begin to reconstruct their shattered sense of social value. However, stigma remains strong, and antiretroviral treatment users remain mired in conflictual symbolic relationships between the HIV/AIDS people and the untested. To date, the restoration of users' own sense of self-worth through treatment has not reduced fear and sexual embarrassment in framing community responses to people living with HIV/AIDS. Much remains to be learned about the complex interaction of economic and psychosocial dimensions of poverty, treatment availability, and conservative sexual moralities in driving HIV/AIDS stigma in specific settings.

Eichen, Dawn M; Matheson, Brittany E; Appleton-Knapp, Sara L; Boutelle, Kerri N

2017-09-01

Recent research has highlighted executive function and neurocognitive deficits among individuals with eating and weight disorders, identifying a potential target for treatment. Treatments targeting executive function for eating and weight disorders are emerging. This review aims to summarize the recent literature evaluating neurocognitive/executive function-oriented treatments for eating and weight disorders and highlights additional work needed in this area. Cognitive remediation therapy (CRT) for anorexia nervosa has been the most extensively studied neurocognitive treatment for eating disorders. Results demonstrate that CRT improves executive function and may aid in the reduction of eating disorder symptomatology. Computer training programs targeting modifying attention and increasing inhibition are targeting reduction of binge eating and weight loss with modest success. Neurocognitive treatments are emerging and show initial promise for eating and weight disorders. Further research is necessary to determine whether these treatments can be used as stand-alone treatments or whether they need to be used as an adjunct to or in conjunction with other evidence-based treatments to improve outcomes.

Cabral, Claudia Valeria Tavora; Filho, Delly Oliveira; Martins, Jose Helvecio

Photovoltaic systems utilize solar energy to generate electrical energy to meet load demands. Optimal sizing of these systems includes the characterization of solar radiation. Solar radiation at the Earth's surface has random characteristics and has been the focus of various academic studies. The objective of this study was to stochastically analyze parameters involved in the sizing of photovoltaic generators and develop a methodology for sizing of stand-alone photovoltaic systems. Energy storage for isolated systems and solar radiation were analyzed stochastically due to their random behavior. For the development of the methodology proposed stochastic analysis were studied including the Markov chainmore » and beta probability density function. The obtained results were compared with those for sizing of stand-alone using from the Sandia method (deterministic), in which the stochastic model presented more reliable values. Both models present advantages and disadvantages; however, the stochastic one is more complex and provides more reliable and realistic results. (author)« less

The primary goal of this grant has been the design and implementation of software to be used in the conceptual design of aerospace vehicles particularly focused on the elements of geometric design, graphical user interfaces, and the interaction of the multitude of software typically used in this engineering environment. This has resulted in the development of several analysis packages and design studies. These include two major software systems currently used in the conceptual level design of aerospace vehicles. These tools are SMART, the Solid Modeling Aerospace Research Tool, and EASIE, the Environment for Software Integration and Execution. Additional software tools were designed and implemented to address the needs of the engineer working in the conceptual design environment. SMART provides conceptual designers with a rapid prototyping capability and several engineering analysis capabilities. In addition, SMART has a carefully engineered user interface that makes it easy to learn and use. Finally, a number of specialty characteristics have been built into SMART which allow it to be used efficiently as a front end geometry processor for other analysis packages. EASIE provides a set of interactive utilities that simplify the task of building and executing computer aided design systems consisting of diverse, stand-alone, analysis codes. Resulting in a streamlining of the exchange of data between programs reducing errors and improving the efficiency. EASIE provides both a methodology and a collection of software tools to ease the task of coordinating engineering design and analysis codes.

to characterize the seropositive elderly for the Human Immunodeficiency Virus and Acquired Immunodeficiency Syndrome (HIV/AIDS) in their socio-demographic aspects; to understand how the elderly take care of themselves from the diagnosis of HIV/AIDS. Qualitative, descriptive, exploratory research conducted at a Voluntary Counseling and Testing Center with 10 elderly people receiving treatment for HIV/AIDS. The data were analyzed according to the content analysis. Data show the elderly people's lack of knowledge about HIV/AIDS transmission, the experience of being elderly and having HIV/AIDS, caring for oneself and life after diagnosis of HIV/AIDS in their daily lives. Final considerations: The diagnosis of HIV/AIDS seropositivity in the elderly generates a blend of feelings and fears that lead to food changes, adherence to treatment and the renunciation of daily and social habits, manifested as ways of self-care.

2014-07-01

To delineate the trajectories of loneliness and self-esteem over time among children affected by parental HIV and AIDS, and to examine how their perceived social support (PSS) influenced initial scores and change rates of these two psychological outcomes. We collected longitudinal data from children affected by parental HIV/AIDS in rural central China. Children 6-18 years of age at baseline were eligible to participate in the study and were assessed annually for 3 years. Multilevel regression models for change were used to assess the effect of baseline PSS on the trajectories of loneliness and self-esteem over time. We employed maximum likelihood estimates to fit multilevel models and specified the between-individual covariance matrix as 'unstructured' to allow correlation among the different sources of variance. Statistics including -2 Log Likelihood, Akaike Information Criterion and Bayesian Information Criterion were used in evaluating the model fit. The results of multilevel analyses indicated that loneliness scores significantly declined over time. Controlling for demographic characteristics, children with higher PSS reported significantly lower baseline loneliness score and experienced a slower rate of decline in loneliness over time. Children with higher PSS were more likely to report higher self-esteem scores at baseline. However, the self-esteem scores remained stable over time controlling for baseline PSS and all the other variables. The positive effect of PSS on psychological adjustment may imply a promising approach for future intervention among children affected by HIV/AIDS, in which efforts to promote psychosocial well being could focus on children and families with lower social support. We also call for a greater understanding of children's psychological adjustment process in various contexts of social support and appropriate adaptations of evidence-based interventions to meet their diverse needs.

This study aimed to examine the psychosocial health status of adult cochlear implant (CI) users, compared to that of hearing aid (HA) users, hearing-impaired adults without hearing aids and normally hearing adults. Cross-sectional observational study, using both self-reported survey data and a speech-in-noise test. Data as collected within the Netherlands Longitudinal Study on Hearing (NL-SH) between September 2011 and June 2016 were used. Data from 1254 Dutch adults (aged 23-74), selected in a convenience sample design, were included for analyses. Psychosocial health measures included emotional and social loneliness, anxiety, depression, distress and somatisation. Psychosocial health, hearing status, use of hearing technology and covariates were measured by self-report; hearing ability was assessed through an online digit triplet speech-in-noise test. After adjusting for the degree of hearing impairment, HA users (N = 418) and hearing-impaired adults (N = 247) had significantly worse scores on emotional loneliness than CI users (N = 37). HA users had significantly higher anxiety scores than CI users in some analyses. Non-significant differences were found between normally hearing (N = 552) and CI users for all psychosocial outcomes. Psychosocial health of CI users is not worse than that of hearing-impaired adults with or without hearing aids. CI users' level of emotional loneliness is even lower than that of their hearing-impaired peers using hearing aids. A possible explanation is that CI patients receive more professional and family support, and guidance along their patient journey than adults who are fitted with hearing aids. © 2017 The Authors.

Access to Aid-in-Dying in the United States: Shifting the Debate From Rights to Justice.

PubMed

Buchbinder, Mara

2018-06-01

Much of the literature on aid-in-dying (AID) has drawn heavily on rights-based ethical and legal frameworks that emphasize patients' rights of self-determination in end-of-life decision-making. Less attention has focused on how terminally ill people actually experience such putative rights once they are legally authorized. This analytic essay draws on findings from the Vermont Study on Aid-in-Dying, an ethnographic study of the implementation of AID in Vermont (2015-2017). First, I show that terminally ill people can face a range of barriers to accessing AID in permissive jurisdictions, and that access to AID is mediated by various inequalities endemic to US health care, as well as some that are unique to AID. I then build on these findings to examine the utility of the concept of justice for public health scholarship on AID. By integrating empirical, ethical, and policy analysis, I reframe rights-based frameworks that emphasize the role of individual choice and decision-making at the end of life. In doing so, I draw attention to health care justice as a neglected issue in public health perspectives on AID.

Caring for people with AIDS: nurses' attitudes and feelings.

PubMed

Breault, A J; Polifroni, E C

1992-01-01

A qualitative, non-experimental study was conducted to identify the feelings and attitudes that nurses associate with caring for people with AIDS. Data collection and analysis were guided by the phenomenological method. Cognitive dissonance theory served as the theoretical framework to view the experience of caring for someone with AIDS. Data analysis of audiotaped, semi-structured interviews resulted in the identification of six mutually inclusive as well as exclusive themes which represent the attitudes and feelings of nurses: fear, anger, sympathy, self-enhancement, fatigue and helplessness. Particularly evident were differences in the way respondents perceived and treated AIDS patients who are intravenous drug users and those who are homosexuals.

Only Behavioral But Not Self-Report Measures of Speech Perception Correlate with Cognitive Abilities.

Good speech perception and communication skills in everyday life are crucial for participation and well-being, and are therefore an overarching aim of auditory rehabilitation. Both behavioral and self-report measures can be used to assess these skills. However, correlations between behavioral and self-report speech perception measures are often low. One possible explanation is that there is a mismatch between the specific situations used in the assessment of these skills in each method, and a more careful matching across situations might improve consistency of results. The role that cognition plays in specific speech situations may also be important for understanding communication, as speech perception tests vary in their cognitive demands. In this study, the role of executive function, working memory (WM) and attention in behavioral and self-report measures of speech perception was investigated. Thirty existing hearing aid users with mild-to-moderate hearing loss aged between 50 and 74 years completed a behavioral test battery with speech perception tests ranging from phoneme discrimination in modulated noise (easy) to words in multi-talker babble (medium) and keyword perception in a carrier sentence against a distractor voice (difficult). In addition, a self-report measure of aided communication, residual disability from the Glasgow Hearing Aid Benefit Profile, was obtained. Correlations between speech perception tests and self-report measures were higher when specific speech situations across both were matched. Cognition correlated with behavioral speech perception test results but not with self-report. Only the most difficult speech perception test, keyword perception in a carrier sentence with a competing distractor voice, engaged executive functions in addition to WM. In conclusion, any relationship between behavioral and self-report speech perception is not mediated by a shared correlation with cognition.

Bolton, Susan; Walson, Judd L.

2013-01-01

Although the social, economic, and political dimensions of the HIV/AIDS epidemic have been studied in considerable depth, the relationship between HIV/AIDS and its environmental causes and consequences remains largely unexplored. We reviewed the evidence of interactions between ecosystem health and the HIV/AIDS pandemic. We hypothesized a syndemic between environmental degradation and HIV/AIDS; they exhibit bidirectional, self-reinforcing interactions. We have presented a syndemic framework detailing multiple synergistic relationships. This framework hinges on the vulnerability of populations as the linchpin between the pandemic and environmental health. A coherent research and practice agenda for addressing the syndemic that focuses on the 2 issues as not only concurrent but also intertwined phenomena is urgently needed. PMID:23237167

Assembly and insertion of a self-fitting hearing aid: design of effective instruction materials.

PubMed

Caposecco, Andrea; Hickson, Louise; Meyer, Carly

A self-fitting hearing aid has been proposed as a viable option to meet the need for rehabilitation in areas where audiology services are unreliable. A successful outcome with a self-fitting hearing aid pivots in part on the clarity of the instructions accompanying the device. The aims of this article are (a) to review the literature to determine features that should be incorporated into written health-care materials and factors to consider in the design process when developing written instructions for a target audience of older adults and (b) to apply this information to the development of a set of written instructions as the first step in self-fitting of a hearing aid, assembling four parts and inserting the aid into the ear. The method involved a literature review of published peer reviewed research. The literature revealed four steps in the development of written health-care materials: planning, design, assessment of suitability, and pilot testing. Best practice design principles for each step were applied in the development of instructions for how to assemble and insert a hearing aid. Separate booklets were developed for the left and right aids and the content of each consisted of simple line drawings accompanied by captions. The reading level was Grade 3.5 equivalent and the Flesch Reading Ease Score was 91.1 indicating that the materials were "very easy" to read. It is essential to follow best practice design principles when developing written health-care materials to motivate the reader, maximize comprehension, and increase the likelihood of successful application of the content.

Development and Validity Testing of an Arthritis Self-Management Assessment Tool.

PubMed

Oh, HyunSoo; Han, SunYoung; Kim, SooHyun; Seo, WhaSook

Because of the chronic, progressive nature of arthritis and the substantial effects it has on quality of life, patients may benefit from self-management. However, no valid, reliable self-management assessment tool has been devised for patients with arthritis. This study was conducted to develop a comprehensive self-management assessment tool for patients with arthritis, that is, the Arthritis Self-Management Assessment Tool (ASMAT). To develop a list of qualified items corresponding to the conceptual definitions and attributes of arthritis self-management, a measurement model was established on the basis of theoretical and empirical foundations. Content validity testing was conducted to evaluate whether listed items were suitable for assessing arthritis self-management. Construct validity and reliability of the ASMAT were tested. Construct validity was examined using confirmatory factor analysis and nomological validity. The 32-item ASMAT was developed with a sample composed of patients in a clinic in South Korea. Content validity testing validated the 32 items, which comprised medical (10 items), behavioral (13 items), and psychoemotional (9 items) management subscales. Construct validity testing of the ASMAT showed that the 32 items properly corresponded with conceptual constructs of arthritis self-management, and were suitable for assessing self-management ability in patients with arthritis. Reliability was also well supported. The ASMAT devised in the present study may aid the evaluation of patient self-management ability and the effectiveness of self-management interventions. The authors believe the developed tool may also aid the identification of problems associated with the adoption of self-management practice, and thus improve symptom management, independence, and quality of life of patients with arthritis.

Major improvements have been completed in the approach to analyses and simulation of spacecraft radiation shielding and exposure. A computer-aided design (CAD)-based system has been developed for determining the amount of shielding provided by a spacecraft and simulating transmission of an incident radiation environment to any point within or external to the vehicle. Shielding analysis is performed using a customized ray-tracing subroutine contained within a standard engineering modeling software package. This improved shielding analysis technique has been used in several vehicle design programs such as a Mars transfer habitat, pressurized lunar rover, and the redesigned international Space Station. Results of analysis performed for the Space Station astronaut exposure assessment are provided to demonastrate the applicability and versatility of the system.

Experience with dc photovoltaic systems (without backup power) and ranging in output from 23 to 3,500 peak watts, in a wide range of environmental conditions and with a wide range of insolation, is described. Cooperation of NASA with other government agencies resulted in the installation of an air pollution monitor in New Jersey, a seismic sensor in Hawaii, power for lookout towers in national forests in California, an electric power system for a Papago Indian village in Arizona, and a power system for a grain mill and water pump in Tangaye, Upper Volta. Significant operational results are discussed and system reliability is assessed for the 20 experimental systems installed since 1976. Additional systems to be installed overseas are highlighted, and economic factors are considered.

To examine the effectiveness of the Listening and Communication Enhancement (LACE) program as a supplement to standard-of-care hearing aid intervention in a Veteran population. A multisite randomized controlled trial was conducted to compare outcomes following standard-of-care hearing aid intervention supplemented with (1) LACE training using the 10-session DVD format, (2) LACE training using the 20-session computer-based format, (3) placebo auditory training (AT) consisting of actively listening to 10 hr of digitized books on a computer, and (4) educational counseling-the control group. The study involved 3 VA sites and enrolled 279 veterans. Both new and experienced hearing aid users participated to determine if outcomes differed as a function of hearing aid user status. Data for five behavioral and two self-report measures were collected during three research visits: baseline, immediately following the intervention period, and at 6 months postintervention. The five behavioral measures were selected to determine whether the perceptual and cognitive skills targeted in LACE training generalized to untrained tasks that required similar underlying skills. The two self-report measures were completed to determine whether the training resulted in a lessening of activity limitations and participation restrictions. Outcomes were obtained from 263 participants immediately following the intervention period and from 243 participants 6 months postintervention. Analyses of covariance comparing performance on each outcome measure separately were conducted using intervention and hearing aid user status as between-subject factors, visit as a within-subject factor, and baseline performance as a covariate. No statistically significant main effects or interactions were found for the use of LACE on any outcome measure. Findings from this randomized controlled trial show that LACE training does not result in improved outcomes over standard-of-care hearing aid intervention alone. Potential benefits of AT may be different than those assessed by the performance and self-report measures utilized here. Individual differences not assessed in this study should be examined to evaluate whether AT with LACE has any benefits for particular individuals. Clinically, these findings suggest that audiologists may want to temper the expectations of their patients who embark on LACE training.

Waweru, Sylvia M; Reynolds, Annette; Buckner, Ellen B

2008-01-01

Perceptions of children's self-concept and associated emotional indicators were assessed in two populations, United States and Kenya, in children living with HIV/AIDS. Assessment of the self-concept mode of the Roy Adaptation Model used both verbal and nonverbal strategies. The sample of children (N = 48), ages 7 to 12 years who were HIV-positive, was recruited from a family clinic that cares for children with chronic illness in the United States (n = 6) and an orphanage that provides for HIV-positive children in Kenya (n = 42). Self-concept was measured using a modification of Piers-Harris Self-Concept Scale. Emotional indicators were measured from Human Figure Drawings (HFD) described by Koppitz (1968). All U.S. children were found to have an average self-concept and one-third demonstrated significant emotional indicators. In Kenya, 93% of the participants had an average self-concept and half were found to have significant emotional indicators. HFD can be used with other screening tools to perform a psychosocial assessment and screening for referral. This study contributes to nursing science by introducing a model-based assessment with cross-cultural applicability.

Self-care practices and experiences of people living with HIV not receiving antiretroviral therapy in an urban community of Lusaka, Zambia: implications for HIV treatment programmes

PubMed Central

2013-01-01

Background Despite the increasingly wider availability of antiretroviral therapy (ART), some people living with HIV (PLHIV) and eligible for treatment have opted to adopt self-care practices thereby risking early AIDS-related mortality. Methods A qualitative study was conducted in urban Zambia to gain insights into PLHIV self-care practices and experiences and explore the implications for successful delivery of ART care. Between March 2010 and September 2011, in-depth interviews were conducted with PLHIV who had dropped out of treatment (n=25) and those that had opted not to initiate medication (n=37). Data was entered into and managed using Atlas ti, and analysed inductively using latent content analysis. Results PHIV used therapeutic and physical health maintenance, psychological well-being and healthy lifestyle self-care practices to maintain physical health and mitigate HIV-related symptoms. Herbal remedies, faith healing and self-prescription of antibiotics and other conventional medicines to treat HIV-related ailments were used for therapeutic and physical health maintenance purposes. Psychological well-being self-care practices used were religiosity/spirituality and positive attitudes towards HIV infection. These practices were modulated by close social network relationships with other PLHIV, family members and peers, who acted as sources of emotional, material and financial support. Cessations of sexual relationships, adoption of safe sex to avoid re-infections and uptake of nutritional supplements were the commonly used risk reduction and healthy lifestyle practices respectively. Conclusions While these self-care practices may promote physical and psychosocial well-being and mitigate AIDS-related symptoms, at least in the short term, they however undermine PLHIV access to ART care thereby putting PLHIV at risk of early AIDS-related mortality. The use of scientifically unproven herbal remedies raises health and safety concerns; faith healing may create fatalism and resignation with death while the reported self-prescription of antibiotics to treat HIV-related infections raises concerns about future development of microbial drug resistance amongst PLHIV. Collectively, these self-care practices undermine efforts to effectively abate the spread and burden of HIV and reduce AIDS-related mortality. Therefore, there is need for sensitization campaigns on the benefits of ART and the risks associated with widespread self-prescription of antibiotics and use of scientifically unproven herbal remedies.

2005-01-01

To assess how people living with HIV and AIDS reacted to the knowledge of the infection and how they are coping with stigma and discrimination. The study was conducted in the two high density urban suburbs of Mabvuku and Tafara in Harare, Zimbabwe. The study was a descriptive cross sectional survey. A total of 600 participants (160 men and 440 women) who had received their HIV results after Voluntary Counselling and Testing for HIV at the Zimbabwe AIDS Prevention and Support Organization (ZAPSO) Mabvuku/Tafara Voluntary Counselling and Testing Centre were interviewed. Reactions to the diagnosis of HIV, disclosure of sero-status, experiences of self, family and community induced stigma and discrimination, coping mechanisms and desired interventions to reduce stigma. The majority, 61.7%, had been diagnosed HIV positive less than two years at the time of the study. While 33.3% felt hurt, 41% were immediately depressed when they discovered they were HIV positive. Eighty five percent had not disclosed their sero-status to anyone. While 55% experience self induced stigma, 56.7% experienced family induced and 38.3% experienced community induced stigma. People living with HIV and AIDS were coping with stigma through withdrawal (60%); joining support groups (83.3%); seeking counselling (95%) and praying (86.7%). Encouraging community counselling and HIV testing with disclosure of status was perceived by 98.3% of the respondents as an effective method to reduce HIV and AIDS related stigma and discrimination. While non disclosure of sero status is still high, self, family and community induced stigma pose a big challenge. Withdrawal (used mostly by men), seeking counselling and joining support groups (used mostly by older women) are the common coping behaviours being used by HIV positive clients. There is need to improve counselling capacities so as to meet the demands from a stigma reduction perspective as well as from a coping perspective.

2006-10-01

The purpose of this cross-sectional study is to examine how personality traits such as sensation- seeking and impulsive decision-making affect Taiwanese college students' intentions to seek online information about sexually transmitted diseases (STDs) and human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS). Five hundred thirty-five (n = 535) junior and senior college students in Taiwan were recruited and completed self-report questionnaires. This study found high sensation-seekers were more likely to seek information about STDs and HIV/AIDS on the Internet than low sensation-seekers. Impulsive decision-makers were less likely than rational decision-makers to seek information about STDs and HIV/AIDS on the Internet. These findings suggest that personality needs to be considered as an exploratory factor which potentially influences intentions to seek STD and HIV/AIDS information on the Internet among Taiwanese college students.

Nurse aide decision making in nursing homes: factors affecting empowerment.

Chaudhuri, Tanni; Yeatts, Dale E; Cready, Cynthia M

2013-09-01

To evaluate factors affecting structural empowerment among nurse aides in nursing homes. Structural empowerment can be defined as the actual rather than perceived ability to make autonomous decisions within an organisation. Given the paucity of research on the subject, this study helps to close the gap by identifying factors that affect nurse aide empowerment, that is, decision-making among nurse aides. The data for the study come from self-administered questionnaires distributed to direct-care workers (nurse aides) in 11 nursing homes in a southern state in the USA. Ordinary least square regression models were estimated to analyse the effects of demographic predictors, personal factors (competency, emotional exhaustion and positive attitude) and structural characteristics (coworker and supervisor support, information availability and shared governance) on nurse aide decision-making. Findings suggest race among demographic predictors, emotional exhaustion among personal characteristics, and supervisor support, and shared governance among structural factors, significantly affect nurse aide decision-making. It is important to explore race as one of the central determinants of structural empowerment among nurse aides. In addition, the nature and type of emotional exhaustion that propels decision-making needs to be further examined. The study shows the importance of shared governance and supervisor support for fostering nurse aide empowerment. © 2013 Blackwell Publishing Ltd.

Performance comparison investigation on solar photovoltaic-thermoelectric generation and solar photovoltaic-thermoelectric cooling hybrid systems under different conditions

Wu, Shuang-Ying; Zhang, Yi-Chen; Xiao, Lan; Shen, Zu-Guo

2018-07-01

The performance of solar photovoltaic-thermoelectric generation hybrid system (PV-TGS) and solar photovoltaic-thermoelectric cooling hybrid system (PV-TCS) under different conditions were theoretically analysed and compared. To test the practicality of these two hybrid systems, the performance of stand-alone PV system was also studied. The results show that PV-TGS and PV-TCS in most cases will result in the system with a better performance than stand-alone PV system. The advantage of PV-TGS is emphasised in total output power and conversion efficiency which is even poorer in PV-TCS than that in stand-alone PV system at the ambient wind speed uw being below 3 m/s. However, PV-TCS has obvious advantage on lowering the temperature of PV cell. There is an obvious increase in tendency on the performance of PV-TGS and PV-TCS when the cooling capacity of two hybrid systems varies from around 0.06 to 0.3 W/K. And it is also proved that not just a-Si in PV-TGS can produce a better performance than the stand-alone PV system alone at most cases.

HIV has become a chronic disease. Therefore, the mental health and sleep quality of people living with HIV/AIDS (PLWHA) have become increasingly important issues of concern. To explore the sleep quality, depression, anxiety, and self-esteem of PLWHA and the correlation between sleep quality and various related mental-health factors. A cross-sectional, descriptive, correlational study was conducted at a medical center in southern Taiwan in 2013-2014. Data on the sleep quality, depression, anxiety, and self-esteem of 146 PLWHA cases were collected using a structural questionnaire (the Pittsburgh Sleep Quality Index, the Center for Epidemiologic Studies Depression Scale, Zung's Self-Administered Anxiety Scale, and Rosenberg Self-Esteem Scale). Three-fifths (60.3%) of the cases had poor sleep quality, 50% were inclined toward depression, and 36.3% were inclined toward anxiety, indicating that sleep quality, depression, and anxiety levels in these cases were worse than the general population. Moreover, significant correlations were identified between poor sleep quality and the variables of depression (r = .40, p < .001) and anxiety (r = .53, p < .001). Multiple variate analysis revealed that older age, subjective feelings that HIV significantly influenced personal life, anxiety, and depression were all significant predictors of sleep quality. No significant correlations were found between CD4 (cluster of differentiation 4) lymphocyte count, HIV viral load, or receiving antiretroviral therapy and the variables of sleep quality, depression, anxiety, or self-esteem. About half of the PLWHA cases in the present study exhibited poor sleep quality and tendencies toward depression and anxiety. Moreover, sleep quality and mental health factors were found to be not correlated with CD4 lymphocyte count, HIV viral load, or receiving antiretroviral therapy. Therefore, early evaluation of the sleep quality and mental health of people living with HIV/AIDS is recommended in order to provide holistic care.

The study compares the audiological profile of a group of first-time applicants for hearing aids, a group of re-applicants and a group of non-complainers, aged 70-75 years (n = 71). In spite of overlap in range, a significant difference in thresholds and discrimination was found. The lip-reading capacity was well preserved in the elderly, but showed a significant correlation to the general health condition. The audiological benefit of hearing-aids did not increase with early fitting. General satisfaction with life was independent of satisfaction with hearing; two thirds of the patients were satisfied with their aids and used them regularly. The rest were dissatisfied and used them less than once a week. The aids were most systematically used to watch TV. Pure-tone average and handicap scaling were compared as guidelines for hearing-aid fitting. The most powerful tool to identify those in need of hearing-aids was handicap scaling based on interviews concerning self-assessed hearing difficulties.

Predicting clinical image delivery time by monitoring PACS queue behavior.

PubMed

King, Nelson E; Documet, Jorge; Liu, Brent

2006-01-01

The expectation of rapid image retrieval from PACS users contributes to increased information technology (IT) infrastructure investments to increase performance as well as continuing demands upon PACS administrators to respond to "slow" system performance. The ability to provide predicted delivery times to a PACS user may curb user expectations for "fastest" response especially during peak hours. This, in turn, could result in a PACS infrastructure tailored to more realistic performance demands. A PACS with a stand-alone architecture under peak load typically holds study requests in a queue until the DICOM C-Move command can take place. We investigate the contents of a stand-alone architecture PACS RetrieveSend queue and identified parameters and behaviors that enable a more accurate prediction of delivery time. A prediction algorithm for studies delayed in a stand-alone PACS queue can be extendible to other potential bottlenecks such as long-term storage archives. Implications of a queue monitor in other PACS architectures are also discussed.

A self-contained, self-fitting hearing aid (SFHA) is a device that enables the user to perform both threshold measurements leading to a prescribed hearing aid setting and fine-tuning, without the need for audiological support or access to other equipment. The SFHA has been proposed as a potential solution to address unmet hearing health care in developing countries and remote locations in the developed world and is considered a means to lower cost and increase uptake of hearing aids in developed countries. This article reviews the status of the SFHA and the evidence for its feasibility and challenges and predicts where it is heading. Devices that can be considered partly or fully self-fitting without audiological support were identified in the direct-to-consumer market. None of these devices are considered self-contained as they require access to other hardware such as a proprietary interface, computer, smartphone, or tablet for manipulation. While there is evidence that self-administered fitting processes can provide valid and reliable results, their success relies on user-friendly device designs and interfaces and easy-to-interpret instructions. Until these issues have been sufficiently addressed, optional assistance with the self-fitting process and on-going use of SFHAs is recommended. Affordability and a sustainable delivery system remain additional challenges for the SFHA in developing countries. Future predictions include a growth in self-fitting products, with most future SFHAs consisting of earpieces that connect wirelessly with a smartphone and providers offering assistance through a telehealth infrastructure, and the integration of SFHAs into the traditional hearing health-care model.

Relatively little is known about the influence of patients' personality features on the responses they make to self-assessment items used to measure the outcome of a hearing aid fitting. If the personality of the hearing aid wearer has a significant influence on self-report outcome data, it would be important to explore the relevant personality variables and to be cognizant of their effects when using subjective outcome data to justify decisions about clinical services or other matters. This investigation explored the relationship between several personality attributes and responses to the Abbreviated Profile of Hearing Aid Benefit (APHAB). It found that more extroverted patients tend to report more hearing aid benefit in all speech communication situations. In addition, patients with a more external locus of control tend to have more negative reactions to loud environmental sounds, both with and without amplification. Anxiety also played a small additional role in determining APHAB responses. Although personality variables were found to explain a relatively small amount of the variance in APHAB responses (usually around 10%), these outcomes should alert practitioners and researchers to the potential effects of personality variables in all self-report data.

To understand the related knowledge, discrimination attitudes toward HIV/AIDS among medical college students, and to provide scientific evidence for further HIV/AIDS anti-discrimination intervention. By means of stratified cluster sampling to classes, 2844 undergraduate students were randomly selected from medical colleges. A self-designed and self-administered questionnaire survey was conducted, and SPSS 13.0 software was used for data analysis. 2501 valid questionnaires had been collected. The overall HIV/AIDS knowledge coverage rate of the respondents was 73.1% (1828/2501); The HIV/AIDS discrimination rates in different questions were varying, the discrimination rate of infected with AIDS by bad sex and sharing needles was 83.1% (2078/2501) and 77.7% (1943/2501) respectively, the discrimination rates in term of contacting with HIV patients and their daily necessities, sharing desks, personal social were all exceeding 40%. The medical students held serious discrimination attitudes to HIV infected persons and patients; it is necessary to strengthen anti-discrimination education about HIV/AIDS among medical students.

This study was conducted to develop an android based patient decision aid (PDA) as a self-care instrument for patients after kidney transplant and its usability evaluation. In this study, the systematic development process of Android-based self-care application for patients after kidney transplant based on Ottawa standard was included: scoping, assemble steering group, analysis of requirements, designing, develop of a prototype and system evaluation. The PDA is a self-triage system that will help early identification of risk symptoms in patients, and help manage them. System recommendations for risk signs are: Refer to the nearest hospital or healthcare center without delay, refer to the doctor and tell your doctor in the next visit. To identify patient care needs, a semi-structured interview with members of steering group, including patients and clinical experts, was conducted by the researchers. A prototype of the decision aid was made according to identified needs in the previous step. Finally, in order to evaluate its usability rate by using the System Usability Scale (SUS) questionnaire, it was used by exerts and patients. This study identified information needs, risk signs and steps that patients need to make appropriate decisions about them. The main capabilities of the decision aid are features such as reminders for appointment/test, time of taking medication, registration of symptoms, weight, blood pressure, body temperature, advising to patient in case of signs of risk, weight, blood pressure, body temperature and test results which were reported in the diagram. The mean score of system's usability evaluated by medical informatics specialists, clinicians, and patients were 88.33, 95, and 91. PDAs was usable and desirable from the point of view of medical informatics specialists, clinicians and patients.

The current study was designed to explore the effect of future orientation in mediating the relationship between traumatic events and mental health in children affected by HIV/AIDS in rural China. Cross-sectional data were collected from 1221 children affected by HIV/AIDS (755 AIDS orphans and 466 vulnerable children). Future orientation among children was measured using three indicators (future expectation, hopefulness toward the future, and perceived control over the future). Measures of mental health consisted of depression, loneliness, and self-esteem. Children's experience of any traumatic events was measured using a modified version of the Life Incidence of Traumatic Events-Student Form. Mediation analysis was conducted using structural equation modeling (SEM) methods. Among the children surveyed, most of the traumatic indicators were negatively associated with future expectation, hopefulness, perceived control, and self-esteem, and positively associated with depression and loneliness. The SEM of mediation analysis demonstrated an adequate fit. Future orientation fully mediated the relationship between traumatic events and mental health and accounted for 67.9% of the total effect of traumatic events on mental health. Results of this study support the positive effect of future expectation in mediating the relationship between traumatic events and mental health among children affected by HIV/AIDS in China. Future mental health promotion and intervention efforts targeting children affected by HIV/AIDS should include components that can mitigate the negative impact of traumatic events on their lives. These components may aim to develop children's positive future expectations, increase their hopefulness toward the future, and improve their perceived control over the future.

An online survey, Care of the Older Adult with Cardiovascular Disease (COA-CVD), was used to describe self-rated competency in the care of the aging adult with cardiovascular disease and subsequently determine the future education and programming needs of the Council of Cardiovascular Nursing. Respondents indicated that developing relationships, patient teaching, and assessment were areas where they felt most competent. The areas of highest priority for future programming included assessment of the older adult, diagnosis of health status, deriving a plan of care, implementing a treatment plan, patient teaching, and ensuring quality care. Most stated that content relative to the care of the older adult should be available at the annual meeting, Scientific Sessions of the American Heart Association, followed by self-study modules (65%), local and regional conferences (64%), and stand-alone national conferences (53%). The conclusions are that the Council of Cardiovascular Nursing and its membership need to address the importance of care of aging adults with cardiovascular disease and stroke in future programming. Although the Scientific Sessions of the American Heart Association is an appropriate venue, efforts can be directed toward developing self-study modules and local and regional conferences. As always, there is a need to work collaboratively with the other councils of the American Heart Association and other nursing organizations who view the care of the older adult as a high priority.

My secret: the social meaning of HIV/AIDS stigma.

This study uses Goffman's [1963. Stigma: Notes on the Management of Spoiled Identity, New Jersey, Prentice-Hall] theory of stigma as an intellectual scaffold to help understand the social meaning of HIV/AIDS stigma from People Living with HIV/AIDS. The study adopts a qualitative approach because of its appropriateness for unravelling subjective phenomena such as the experiences of HIV/AIDS stigma. In-depth interviews were conducted with 10 HIV-positive employees of a retailing company located in the Western Cape province of South Africa who volunteered to participate in the study. The participants with the discreditable stigma internalised society's prejudice towards those living with the virus. As a result, the participants relied on self-isolation and social withdrawal to cope with enacted stigma. Managing information about one's status and deciding whether, who, when, etc., to tell are crucial questions. The participants feared being devalued by family, friends, co-workers and the community. In concurrence with Goffman [1963], the HIV/AIDS stigma is seen as about relationships.

Ontology-based enrichment analysis aids in the interpretation and understanding of large-scale biological data. Ontologies are hierarchies of biologically relevant groupings. Using ontology annotations, which link ontology classes to biological entities, enrichment analysis methods assess whether there is a significant over or under representation of entities for ontology classes. While many tools exist that run enrichment analysis for protein sets annotated with the Gene Ontology, there are only a few that can be used for small molecules enrichment analysis. We describe BiNChE, an enrichment analysis tool for small molecules based on the ChEBI Ontology. BiNChE displays an interactive graph that can be exported as a high-resolution image or in network formats. The tool provides plain, weighted and fragment analysis based on either the ChEBI Role Ontology or the ChEBI Structural Ontology. BiNChE aids in the exploration of large sets of small molecules produced within Metabolomics or other Systems Biology research contexts. The open-source tool provides easy and highly interactive web access to enrichment analysis with the ChEBI ontology tool and is additionally available as a standalone library.

The RF Probe: providing space situational awareness through broad-spectrum detection and characterization

Zenick, Raymond; Kohlhepp, Kimberly; Partch, Russell

2004-09-01

AeroAstro's patented RF Probe is a system designed to address the needs of spacecraft developers and operators interested in measuring and analyzing near-field RF emissions emanating from a nearby spacecraft of interest. The RF Probe consists of an intelligent spectrum analyzer with digital signal processing capabilities combined with a calibrated, wide-bandwidth antenna and RF front end that covers the 50 kHz to 18 GHz spectrum. It is capable of acquiring signal level and signal vector information, classifying signals, assessing the quality of a satellite"s transponders, and characterizing near-field electromagnetic emissions. The RF Probe is intended for either incorporation as part of a suite of spacecraft sensors, or as a stand-alone sensor on spacecraft or other platforms such as Unmanned Aerial Vehicles (UAVs). The RF Probe was initially conceived as a tool to detect and aid in diagnosis of malfunctions in a spacecraft of interest. However, the utility of the RF Probe goes far beyond this initial concept, spanning a wide range of military applications. Most importantly, the RF Probe can provide space situational awareness for critical on-orbit assets by detecting externally induced RF fields, aiding in protection against potentially devastating attacks.

Relationship Power, Sexual Decision Making, and HIV Risk Among Midlife and Older Women.

Altschuler, Joanne; Rhee, Siyon

2015-01-01

The number of midlife and older women with HIV/AIDS is high and increasing, especially among women of color. This article addresses these demographic realities by reporting on findings about self-esteem, relationship power, and HIV risk from a pilot study of midlife and older women. A purposive sample (N = 110) of ethnically, economically, and educationally diverse women 40 years and older from the Greater Los Angeles Area was surveyed to determine their levels of self-esteem, general relationship power, sexual decision-making power, safer sex behaviors, and HIV knowledge. Women with higher levels of self-esteem exercised greater power in their relationships with their partner. Women with higher levels of general relationship power and self-esteem tend to exercise greater power in sexual decision making, such as having sex and choosing sexual acts. Income and sexual decision-making power were statistically significant in predicting the use of condoms. Implications and recommendations for future HIV/AIDS research and intervention targeting midlife and older women are presented.

Literature suggests that communication is a protective factor against high-risk sexual behavior. This study assessed the impact of a fourth-grade communication-centered life skills program on attitudes, norms, self-efficacy, behaviors, and intentions toward communication about difficult subjects. Participants included 1,581 low-income Mexican elementary-school children, divided into experimental and control groups. Teachers were trained to replicate the program as part of the school curriculum over 15 to 20 weeks. Students completed self-report questionnaires before and after the program. Multilevel analyses demonstrated the program's statistically significant positive impact on communication about attitudes, self-efficacy, intentions, and behavior; perception of sociocultural norms regarding communication transformed as a result of the program. Gender significantly predicted differences in communication: with respect to attitudes, self-efficacy, and intentions. The results show that early intervention programs targeting communication about difficult subjects can prevent risky sexual behavior and its consequences (e.g., HIV/AIDS) and influence perception of norms and gender roles.

The relationship between social roles and self-management behavior in women living with HIV/AIDS.

The social roles that women perform can be complicated and may affect their health. While there is some evidence describing traditional social roles of women, there is little evidence exploring the impact of those roles on how a woman manages a chronic condition. The purpose of this paper is to identify and examine the main social roles of 48 HIV infected women, and to explore how these roles relate to their self-management of HIV/AIDS. Forty-eight HIV infected, adult women were recruited from HIV clinics and AIDS service organizations in Northeast Ohio. All participants participated in one of 12 digitially recorded focus groups. All data were analyzed using qualitative description methodology. The participants were predominantly middle-aged (mean = 42 years), African American (69%), and single (58%). Analysis revealed six social roles that these women experience and which affect their self-management. These social roles are: Mother/Grandmother, Believer, Advocate, Stigmatized Patient, Pet Owner, and Employee. These roles had both a positive and negative effect on a woman's self-management of her HIV disease and varied by age and time living with HIV. Women living with HIV/AIDS struggle to manage the many daily tasks required to live well with this disease. The social context in which this self-management happens is important, and the various social roles that women perform can facilitate or hinder them from completing these tasks. Healthcare and social service providers should learn about these roles in their individual patients, particularly how these roles can be developed to increase HIV/AIDS self-management.

2009-05-27

The proportion of older people is increasing worldwide. Globally, it is estimated that older people (those 60 years or older) constitute more than 11% of the population. As the HIV/AIDS pandemic rages in sub-Saharan Africa (SSA), its impact on older people needs closer attention given the increased economic and social roles older people have taken on as a result of increased mortality among adults in the productive age groups. Few studies have looked at older people and their health in SSA or indeed the impact of HIV/AIDS on their health. This study aims to assess the effect of being directly or indirectly affected by HIV/AIDS on the health of older people in two Nairobi slums. Data were collected from residents of the Nairobi Urban Health and Demographic Surveillance area aged 50 years and above on 1st October 2006. Health status was assessed using the short SAGE (Study on Global AGEing and Adult Health) form and two outcome measures--self-rated health and a composite health score--were generated. To assess HIV/AIDS affected status, respondents were asked: Have you personally been affected by HIV/AIDS? If yes, a follow up question: "How have you been personally affected by HIV/AIDS?" was asked. Ordinallogistic regression was used in models with self-rated health and linear regression in models with the health score. About 18% of respondents reported being affected by HIV/AIDS in at least one way, although less than 1% reported being infected with HIV. Nearly 60% of respondents reported being in good health, 27% in fair health and 14% in poor health. The overall mean health score was 70.6 (SD: 13.9) with females reporting worse health outcomes than males. Respondents directly or indirectly affected by HIV/AIDS reported worse health outcomes than those not affected: mean health score: 68.5 and 71.1 respectively (t = 3.21, p = 0.0007), and an adjusted odds ratio of reporting poor health of 1.42 (95%CI: 1.12-1.80). Poor health outcomes among older people affected by HIV/AIDS highlight the need for policies that target them in the fight against HIV/AIDS if they are to play their envisaged care giving and other traditional roles.

2015-01-01

A cross-sectional, experimental, and randomized repeated-measures design study was used to examine the objective and subjective value of telecoil and hearing loop systems. Word recognition and speech perception were tested in 12 older adult hearing aid users using the telecoil and microphone inputs in quiet and noise conditions. Participants were asked to subjectively rate cognitive listening effort and self-confidence for each condition. Significant improvement in speech perception with the telecoil over microphone input in both quiet and noise was found along with significantly less reported cognitive listening effort and high self-confidence. The use of telecoils with hearing aids should be recommended for older adults with hearing loss. PMID:28138458

Using HIV&AIDS statistics in pre-service Mathematics Education to integrate HIV&AIDS education.

PubMed

van Laren, Linda

2012-12-01

In South Africa, the HIV&AIDS education policy documents indicate opportunities for integration across disciplines/subjects. There are different interpretations of integration/inclusion and mainstreaming HIV&AIDS education, and numerous levels of integration. Integration ensures that learners experience the disciplines/subjects as being linked and related, and integration is required to support and expand the learners' opportunities to attain skills, acquire knowledge and develop attitudes and values across the curriculum. This study makes use of self-study methodology where I, a teacher educator, aim to improve my practice through including HIV&AIDS statistics in Mathematics Education. This article focuses on how I used HIV&AIDS statistics to facilitate pre-service teacher reflection and introduce them to integration of HIV&AIDS education across the curriculum. After pre-service teachers were provided with HIV statistics, they drew a pie chart which graphically illustrated the situation and reflected on issues relating to HIV&AIDS. Three themes emerged from the analysis of their reflections. The themes relate to the need for further HIV&AIDS education, the changing pastoral role of teachers and the changing context of teaching. This information indicates that the use of statistics is an appropriate means of initiating the integration of HIV&AIDS education into the academic curriculum.

Role of community health workers in type 2 diabetes mellitus self-management: A scoping review.

2018-01-01

Globally the number of people with Type 2 diabetes mellitus (T2DM) has risen significantly over the last few decades. Aligned to this is a growing use of community health workers (CHWs) to deliver T2DM self-management support with good clinical outcomes especially in High Income Countries (HIC). Evidence and lessons from these interventions can be useful for Low- and Middle-Income countries (LMICs) such as South Africa that are experiencing a marked increase in T2DM prevalence. This study aimed to examine how CHW have been utilized to support T2DM self-management globally, their preparation for and supervision to perform their functions. The review was guided by a stepwise approach outlined in the framework for scoping reviews developed by Arksey and O'Malley. Peer reviewed scientific and grey literature was searched using a string of keywords, selecting English full-text articles published between 2000 and 2015. Articles were selected using inclusion criteria, charted and content analyzed. 1008 studies were identified of which 54 full text articles were selected. Most (53) of the selected studies were in HIC and targeted mostly minority populations in low resource settings. CHWs were mostly deployed to provide education, support, and advocacy. Structured curriculum based education was the most frequently reported service provided by CHWs to support T2DM self-management. Support services included informational, emotional, appraisal and instrumental support. Models of CHW care included facility linked nurse-led CHW coordination, facility-linked CHW led coordination and standalone CHW interventions without facility interaction. CHWs play several roles in T2DM self-management, including structured education, ongoing support and health system advocacy. Preparing and coordinating CHWs for these roles is crucial and needs further research and strengthening.

The EORTC Quality of Life Group has just completed the final phase (field-testing and validation) of an international project to develop a stand-alone measure of spiritual well-being (SWB) for palliative cancer patients. Participants (n = 451)-from 14 countries on four continents; 54% female; 188 Christian; 50 Muslim; 156 with no religion-completed a provisional 36-item measure of SWB plus the EORTC QLQ-C15-PAL (PAL), then took part in a structured debriefing interview. All items showed good score distribution across response categories. We assessed scale structure using principal component analysis and Rasch analysis, and explored construct validity, and convergent/divergent validity with the PAL. Twenty-two items in four scoring scales (Relationship with Self, Relationships with Others, Relationship with Someone or Something Greater, and Existential) explained 53% of the variance. The measure also includes a global SWB item and nine other items. Scores on the PAL global quality-of-life item and Emotional Functioning scale weakly-moderately correlated with scores on the global SWB item and two of the four SWB scales. This new validated 32-item SWB measure addresses a distinct aspect of quality-of-life, and is now available for use in research and clinical practice, with a role as both a measurement and an intervention tool. © 2017 John Wiley & Sons Ltd.

Mobile technologies have wide-scale reach and disseminability, but no known studies have examined mobile technologies as a stand-alone tool to improve obesity-related behaviors of at-risk youth. To test a 12-week mobile technology intervention for use and estimate effect sizes for a fully powered trial. Fifty-one low-income, racial/ethnic-minority girls aged 9-14 years were randomized to a mobile technology (n=26) or control (n=25) condition. Both conditions lasted 12 weeks and targeted fruits/vegetables (FVs; Weeks 1-4); sugar-sweetened beverages (SSBs; Weeks 5-8), and screen time (Weeks 9-12). The mobile intervention prompted real-time goal setting and self-monitoring and provided tips, feedback, and positive reinforcement related to the target behaviors. Controls received the same content in a written manual but no prompting. Outcomes included device utilization and effect size estimates of FVs, SSBs, screen time, and BMI. Data were collected and analyzed in 2011-2012. Mobile technology girls used the program on 63% of days and exhibited trends toward increased FVs (+0.88, p=0.08) and decreased SSBs (-0.33, p=0.09). The adjusted difference between groups of 1.0 servings of FVs (p=0.13) and 0.35 servings of SSBs (p=0.25) indicated small to moderate effects of the intervention (Cohen's d=0.44 and -0.34, respectively). No differences were observed for screen time or BMI. A stand-alone mobile app may produce small to moderate effects for FVs and SSBs. Given the extensive reach of mobile devices, this pilot study demonstrates the need for larger-scale testing of similar programs to address obesity-related behaviors in high-risk youth.

The purpose of this study was to investigate whether the core members' social capital was associated with individually perceived and externally evaluated prestige and cooperation among the HIV/AIDS-related civil society organizations (CSOs). To accomplish this, a cross-sectional study using multistage sampling was carried out in eight provinces of China. Data were collected from the 327 core members via questionnaires and self-evaluated performance of the respondents were evaluated and measured. The interviews were conducted with all core members and the supervisory staff of the local Centers for Disease Control and Prevention. Multivariate logistic regression analysis indicated that social support (adjusted odds ratio [a OR] = 1.87) and organizational commitment (a OR = 1.57) were significantly associated with a higher odds of prestige performance in self-evaluation. Furthermore, social support (a OR = 1.65), trust (a OR = 1.33), and organizational commitment (a OR = 1.52) were significantly correlated with cooperation performance. Trust was positively associated with the cooperation performance on external evaluation. These findings may provide a new perspective on challenges that the CSOs face in response to a growing HIV/AIDS epidemic in China. Social capital may increase performance and accelerate organizational growth, ultimately improving HIV/AIDS prevention and care.

The digital archiving system at Madigan Army Medical Center (MAMC) uses a 10:1 lossy data compression algorithm for most forms of computed radiography. A systematic study on the potential effect of lossy image compression on patient care has been initiated with a series of studies focused on specific diagnostic tasks. The studies are based upon the receiver operating characteristic (ROC) method of analysis for diagnostic systems. The null hypothesis is that observer performance with approximately 10:1 compressed and decompressed images is not different from using original, uncompressed images for detecting subtle pathologic findings seen on computed radiographs of bone, chest, or abdomen, when viewed on a high-resolution monitor. Our design involves collecting cases from eight pathologic categories. Truth is determined by committee using confirmatory studies performed during routine clinical practice whenever possible. Software has been developed to aid in case collection and to allow reading of the cases for the study using stand-alone Siemens Litebox workstations. Data analysis uses two methods, ROC analysis and free-response ROC (FROC) methods. This study will be one of the largest ROC/FROC studies of its kind and could benefit clinical radiology practice using PACS technology. The study design and results from a pilot FROC study are presented.

2017-08-01

In this paper we present a simple, empirical model of stand-alone photovoltaic power system availability. The model is a final result of five-year long studies and ground measurements of solar irradiation carried out in Central Europe. The obtained results facilitate sizing of PV modules that have to be installed with taking into account system's availability level in each month of a year. The model can be extended to different geographical locations, with help of local meteorological data or solar irradiation datasets derived from satellite measurements.

The Safety Pharmacology (SP) Society (SPS) conducted an industry survey in 2012 in an attempt to define current industry practices as they relate to inclusion of safety pharmacology (SP) endpoints into Toxicology studies. A total of 361 participants from Asia (9.1%), Europe (19.4%) and North America (71.4%) responded to the survey. The preponderance of respondents were toxicologists (53.2%) followed by safety pharmacologists (27.2%) and scientists involved in the conduct of both disciplines (19.6%). Most participants (58.6%) were from pharmaceutical companies employing more than 500 employees. A majority (68.2%) reported having experience in designing, performing or interpreting the SP component of a study when performed as part of a toxicology study. Some participants (42.0%) had submitted data to a regulatory agency where ICHS7 studies were performed as part of a toxicology study rather than as a standalone study. When comparing species that were used in studies in which SP was added to toxicology studies, canines were the most frequently reported animals used for new chemical entities (NCE) whereas non-human (NH) primates were the most frequent for the assessment of biological agents. The most frequent primary motivator for adding ICHS7 SP endpoints to regulatory toxicology studies was to generate additional data to allow for determination of an integrated risk assessment thereby testing Confidence in Safety (CIS) to better manage and/or mitigate risk. The current ability to add safety pharmacology endpoints into regulatory toxicology studies was used to address a specific concern (by 42.1% of respondents) to allow management of risk more effectively (36.8%) or to generate data that contributes to cessation of the progression of a compound (21.1%). For an NCE, SP measurements in toxicology studies were conducted in addition to standalone SP studies (by 40.6% of respondents) or in addition/instead of standalone safety pharmacology studies (by 39.8% of respondents). For biological agents, a majority (74.3%) indicated SP measurements in toxicology were conducted instead of standalone studies as outlined in the ICHS6 guideline while inclusion of SP endpoints in toxicology studies for biological agents in addition to standalone studies was reported by only 25.7% of the respondents. The survey highlights that obtaining regulatory agreement for the proposed combined SP/Tox study designs may be useful before study conduct in some cases. Respondents suggest that such discussion could occur at the pre-IND meeting before the IND/CTA enabling program. Copyright © 2013 Elsevier Inc. All rights reserved.

This study compared the solar energy utilization of a closed microalgae-based bio-loop for energy efficient production of biogas with fertilizer recovery against that of a stand-alone photovoltaic (PV) system. The comparison was made from the perspective of broad life cycle assessment, simultaneously taking exergy to be the functional unit. The results indicated that the bio-loop was more environmentally competitive than an equivalent stand-alone PV system, but had higher economic cost due to high energy consumption during the operational phase. To fix the problem, a patented, interior pressurization scheduling method was used to operate the bio-loop, with microalgae and aerobic bacterial placed together in the same reactor. As a result, the overall environmental impact and total investment were respectively reduced by more than 75% and 84%, a vast improvement on the bio-loop. Copyright © 2014 Elsevier Ltd.

The concept of capacitive coupling between sensors and readout chips is under study for the vertex detector at the proposed high-energy CLIC electron positron collider. The CLICpix Capacitively Coupled Pixel Detector (C3PD) is an active High-Voltage CMOS sensor, designed to be capacitively coupled to the CLICpix2 readout chip. The chip is implemented in a commercial 180 nm HV-CMOS process and contains a matrix of 128×128 square pixels with 25μm pitch. First prototypes have been produced with a standard resistivity of ~20 Ωcm for the substrate and tested in standalone mode. The results show a rise time of ~20 ns, charge gain of 190 mV/ke- and ~40 e- RMS noise for a power consumption of 4.8μW/pixel. The main design aspects, as well as standalone measurement results, are presented.

Background Between 2009–2013 the Bill and Melinda Gates Foundation transitioned its HIV/AIDS prevention initiative in India from being a stand-alone program outside of government, to being fully government funded and implemented. We present an independent prospective evaluation of the transition. Methods The evaluation drew upon (1) a structured survey of transition readiness in a sample of 80 targeted HIV prevention programs prior to transition; (2) a structured survey assessing institutionalization of program features in a sample of 70 targeted intervention (TI) programs, one year post-transition; and (3) case studies of 15 TI programs. Findings Transition was conducted in 3 rounds. While the 2009 transition round was problematic, subsequent rounds were implemented more smoothly. In the 2011 and 2012 transition rounds, Avahan programs were well prepared for transition with the large majority of TI program staff trained for transition, high alignment with government clinical, financial and managerial norms, and strong government commitment to the program. One year post transition there were significant program changes, but these were largely perceived positively. Notable negative changes were: limited flexibility in program management, delays in funding, commodity stock outs, and community member perceptions of a narrowing in program focus. Service coverage outcomes were sustained at least six months post-transition. Interpretation The study suggests that significant investments in transition preparation contributed to a smooth transition and sustained service coverage. Notwithstanding, there were substantive program changes post-transition. Five key lessons for transition design and implementation are identified. PMID:26327591

Aims and Objectives: The aim of the present study was to evaluate the knowledge of dentists regarding human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS). Materials and Methods: A structured questionnaire to evaluate the knowledge, fears, and attitudes was self administered to 102 dentists. The data was then evaluated using Chi-square test and a P < 0.05 was considered statistically significant. Results and Conclusion: The findings of the present study suggest that dentists in private practice and affiliated with teaching institutions, had better knowledge than their counterparts who were into private practice alone. It was concluded that despite good knowledge many of the dentists expressed some hesitation in treating patients with HIV/AIDS. PMID:25097403

Factors that influence utilisation of HIV/AIDS prevention methods among university students residing at a selected university campus.

PubMed

2014-01-01

Various studies have reported that university students, who are mostly young people, rarely use existing HIV/AIDS preventive methods. Although studies have shown that young university students have a high degree of knowledge about HIV/AIDS and HIV modes of transmission, they are still not utilising the existing HIV prevention methods and still engage in risky sexual practices favourable to HIV. Some variables, such as awareness of existing HIV/AIDS prevention methods, have been associated with utilisation of such methods. The study aimed to explore factors that influence use of existing HIV/AIDS prevention methods among university students residing in a selected campus, using the Health Belief Model (HBM) as a theoretical framework. A quantitative research approach and an exploratory-descriptive design were used to describe perceived factors that influence utilisation by university students of HIV/AIDS prevention methods. A total of 335 students completed online and manual questionnaires. Study findings showed that the factors which influenced utilisation of HIV/AIDS prevention methods were mainly determined by awareness of the existing university-based HIV/AIDS prevention strategies. Most utilised prevention methods were voluntary counselling and testing services and free condoms. Perceived susceptibility and perceived threat of HIV/AIDS score was also found to correlate with HIV risk index score. Perceived susceptibility and perceived threat of HIV/AIDS showed correlation with self-efficacy on condoms and their utilisation. Most HBM variables were not predictors of utilisation of HIV/AIDS prevention methods among students. Intervention aiming to improve the utilisation of HIV/AIDS prevention methods among students at the selected university should focus on removing identified barriers, promoting HIV/AIDS prevention services and providing appropriate resources to implement such programmes.

What Factors Are Associated with Autonomous and Controlled Motivation for Hearing Help-Seekers?

PubMed

Ridgway, Jason; Hickson, Louise; Lind, Christopher

Hearing impairment is prevalent in older adults. Motivation is important in people's choice to seek help for their hearing and whether to adopt or not adopt hearing aids. To investigate associations between sociodemographic and audiometric characteristics and autonomous and controlled motivation among a sample of hearing help-seekers. A quantitative approach was taken for this cross-sectional cohort study. A total of 253 adult first-time hearing help-seekers were recruited to the study. Participants provided sociodemographic information and completed questionnaires adapted from self-determination theory that measured autonomous motivation (motivation that originates from within the self and is aligned with personal values and beliefs) and controlled motivation (motivation that stems from external pressures such as rewards or punishment, or conflicted inner feelings such as guilt or shame). Participants with higher autonomous motivation scores were younger, wanted hearing aids more, and reported greater hearing difficulty in everyday life than those with lower scores. Participants with higher controlled motivation scores were more often referred to the service by others and wanted hearing aids more than those with lower controlled motivation scores. Controlled motivation scores were not associated with perceptions of hearing difficulty in everyday life. Relationships among motivation and sociodemographic factors highlight the importance of characterizing autonomous and controlled motivation in first-time hearing help-seekers. Attention to personal characteristics in order to understand motivational processes involved in rehabilitation decisions such as hearing aid adoption may aid in consultations.

The self as capital in the narrative economy: how biographical testimonies move activism in the Global South.

Burchardt, Marian

2016-05-01

This article analyses and theorises the practice of biographical storytelling of HIV-positive AIDS activists in South Africa. Combining research in illness narratives, studies of emotions in social activism and analysis of global health institutions in Africa, I explore how biographical self-narrations are deployed to facilitate access to resources and knowledge and thus acquire material and symbolic value. I illustrate my argument through the analysis of the case of an AIDS activist who became a professional biographical storyteller. Based on the analysis which I claim to represent wider dynamics in human-rights-based health activism in the Global South, I propose the concept of narrative economies by which I mean the set of exchange relationships within which biographical self-narrations circulate and produce social value for individuals and organisations. © 2015 Foundation for the Sociology of Health & Illness.

Detecting components of hearing aid fitting using a self-assessment-inventory.

Meister, Hartmut; Lausberg, Isabel; Kiessling, Juergen; von Wedel, Hasso; Walger, Martin

2005-07-01

The evaluation of hearing-aid fitting includes numerous assessments such as electro- and psychoacoustic tests. The subjective estimation of the hearing aid user can be elicited with self-assessment inventories encompassing various parameters, e.g., benefit, satisfaction and usage. A questionnaire comprising 11 domains (disability, handicap, frequency and significance of the listening situation, importance of the hearing aid, expectation, demand, aided performance, benefit, satisfaction and usage) within three different conditions (speech in quiet and in noise and listening to sounds) was used to detect components underlying hearing aid fitting. The data show a three-factor structure (situation-, restriction- and aid-related variables) independent from the conditions. Usage depends on all of the three factors. Disability and handicap reveal the highest values for speech in noise, whereas the aid-related factor shows the lowest values for this condition. Global satisfaction with the hearing aid is significantly correlated with the aid-related factor, but independent from the restriction of hearing. The aid-related factor is positively influenced by the amount of social activity because more active persons report higher benefit and satisfaction for all listening conditions. Age does not exhibit a significant relationship to one of the components. Basically, all correlation coefficients are only intermediate, revealing that inter-individual differences of the patients are rather high. The data indicate that extra-audiological factors might also play an important role in the success of hearing aid fitting.

Internet Competency Predicts Practical Hearing Aid Knowledge and Skills in First-Time Hearing Aid Users.

The purpose of the study was to assess whether Internet competency predicted practical hearing aid knowledge and handling skills in first-time hearing aid users. The design was a prospective, randomized controlled trial of a multimedia educational intervention consisting of interactive video tutorials (or reusable learning objects [RLOs]). RLOs were delivered through DVD for TV or PC, and online. Internet competency was measured at the hearing aid fitting appointment, whereas hearing aid knowledge and practical handling skills were assessed 6 weeks postfitting. Internet competency predicted practical hearing aid knowledge and handling skills, controlling for age, hearing sensitivity, educational status, and gender for the group that received the RLOs. Internet competency was inversely related to the number of times the RLOs were watched. Associations between Internet competency and practical hearing aid knowledge, handling skills, and watching the RLOs fewer times may have arisen because of improved self-efficacy. Therefore, first-time hearing aid users who are more competent Internet users may be better equipped to apply newly learned information to effectively manage their hearing loss.

This study consisted of a survey given to college students (N = 560) at a rural university in the Pacific Northwest. The sample was randomly assigned into four groups, following the Solomon four-group study design. The two levels of treatment included interventions consisting of a visit to the AIDS Memorial Quilt for the experimental groups and attendance at an unrelated event for the control groups. Pretests were completed 4 weeks prior to interventions; posttests were completed by the entire sample 4 weeks after the interventions. Results confirmed expected differences among the four groups in terms of social distance, perceptions of people with AIDS, self-efficacy, and discussion of risky behavior. The results suggest that the AIDS Memorial Quilt addresses issues centrally related to behavior change and indicates support for the message interpretation process and stages of change models.

The After Hours Primary Medical Trials were initiated by the Australian government to redress difficulties in after hours (AH) GP care in areas of high need. The study's objective is to study the impact of two standalone call centres and one GP cooperative offering comprehensive services, in improving consumer access to services for residents of a defined geographic area. A pre-post design was used to evaluate their impact after adjusting for secular trend at a national level. Access was considered in terms of availability, accessibility, affordability, acceptability and responsiveness of care. Unmet need and ease of obtaining AH telephone professional medical advice were also considered. Pre-trial and post-trial telephone surveys of two separate random samples of approximately 350 households using AH services in each trial area as well as in a national sample outside the trial areas. Consumer acceptability and affordability increased in residents in the area served by the GP cooperative. Access, however measured, did not improve in either of the standalone call centre areas. Reduction in unmet need approached but did not achieve statistical significance in most but not all trial areas. Improvements in access in the GP cooperative conformed to expectations based on current and pre-existing AH care arrangements put in place. Absence of improvements in access in the standalone call centres did not conform to expectations but may be partly explained by the reductions in consumer acceptability, following introduction of telephone triage systems reported elsewhere.

The paper deals with a single-phase induction machine operating as a stand-alone self-excited single-phase induction generator for generation of electrical energy from renewable energy sources. By changing number of turns and size of wires in the auxiliary stator winding, an improvement of performance characteristics of the generator were obtained as regards no-load and load voltage of the stator windings as well as stator winding currents of the generator. Field-circuit simulation models of the generator were developed using Flux2D software package for the generator with shunt capacitor in the main stator winding. The obtained results have been validated experimentally at the laboratory setup using the single-phase capacitor induction motor of 1.1 kW rated power and 230 V voltage as a base model of the generator.

Understanding barriers and facilitators of physical activity participation in persons living with HIV/AIDS is an essential first step in order to devise effective interventions. The present review provides a systematic quantitative review of the physical activity correlates in people with HIV/AIDS. Major electronic databases were searched till August 2016. Keywords included "physical activity" or "exercise" or "sports" and "AIDS" or "HIV". Out of 55 correlates from 45 studies (N = 13,167; mean age range = 30.5-58.3 years; 63.2% male) five consistent (i.e., reported in four or more studies) correlates were identified. Lower levels of physical activity were consistently associated with older age (6/10 studies), a lower educational level (6/7), a lower number of CD4 cells/μl (7/11), exposure to antiviral therapy (4/6), and the presence of lipodystrophy (4/4). Other important barriers were the presence of bodily pain (2/2), depression (3/3), and opportunistic infections (3/4). Facilitators were a higher cardiorespiratory fitness level (3/3), a higher self-efficacy (2/2), more perceived benefits (2/2), and a better health motivation (3/3). The current review has elucidated that participation in physical activity by people with HIV/AIDS is associated with a range of complex factors which should be considered in rehabilitation programs. Implications for Rehabilitation Health care professionals should consider HIV-related bodily pain and feelings of depression when assisting people living with HIV in inititiating and maintaining an active lifestyle. Interventions to improve self-efficacy and motivation, and to help people living with HIV in understanding the benefits of exercise, may encourage greater participation.

To analyze satisfaction with health care among African American women living with HIV/AIDS. Secondary analysis of baseline data of African American women who participated in Protect and Respect, a sexual risk reduction program for women living with HIV/AIDS SETTING: HIV Care Clinic in an urban city in the northeast United States. One hundred fifty-seven (157) African American women living with HIV/AIDS. Regression analyses were used to examine the relationships between demographic variables, self-reported health characteristics, communication with health care providers, and satisfaction with health care provider. A majority of women reported satisfaction with medical services (88%, n = 140). Communication with health care providers, detectable viral load, education, income, self-reported health status, and sexual orientation were significantly bivariately associated with satisfaction with healthcare (all ps < .05). In the multivariate models, no variables significantly predicted satisfaction with healthcare. Because satisfaction with health care can influence the quality of care received, health outcomes, and adherence to provider recommendations among patients living with HIV/AIDS, health care providers' ability to elicit satisfaction from their patients is just as important as the services they provide. This project is one of the first studies to find high rates of satisfaction with health care among African American women living with HIV/AIDS. Further examination of satisfaction with health care among African American women living HIV/AIDS may help in narrowing health care disparities and negative treatment outcomes. © 2014 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

Empirical estimation of a distribution function with truncated and doubly interval-censored data and its application to AIDS studies.

Sun, J

In this paper we discuss the non-parametric estimation of a distribution function based on incomplete data for which the measurement origin of a survival time or the date of enrollment in a study is known only to belong to an interval. Also the survival time of interest itself is observed from a truncated distribution and is known only to lie in an interval. To estimate the distribution function, a simple self-consistency algorithm, a generalization of Turnbull's (1976, Journal of the Royal Statistical Association, Series B 38, 290-295) self-consistency algorithm, is proposed. This method is then used to analyze two AIDS cohort studies, for which direct use of the EM algorithm (Dempster, Laird and Rubin, 1976, Journal of the Royal Statistical Association, Series B 39, 1-38), which is computationally complicated, has previously been the usual method of the analysis.

Studies have found a higher risk of burnout among employees in the healthcare sector. As such, this study focused on Certified Nursing Aides (CNAs) who have shown a high prevalence of burnout and are therefore considered an especially vulnerable group. The objective of this study was to identify the relationships between some organizational, personal, and sociodemographic factors and burnout. The final study sample included 278 working CNAs with a mean age of 40.88 (SD = 9.41). To compile the data, an ad hoc questionnaire was used to collect sociodemographic information. To collect professional and employment information, we used the Brief Emotional Intelligence Inventory for Adults, the Brief Questionnaire on Perceived Social Support, and the General Self-Efficacy Scale. The results showed that Burnout Syndrome is significantly and negatively related to all the emotional intelligence factors, self-efficacy, and perceived social support. The risk of burnout is higher in younger persons and in permanently employed professionals. General self-efficacy and stress management act as protective factors against the likelihood of burnout. This study suggests that organizations should urge coaching and transformational leadership training programs to promote the wellbeing and organizational commitment of workers.

Adults and elderly users of hearing aids suffer psychosocial reactions as a result of hearing loss. Auditory rehabilitation is typically carried out with support from a speech therapist, usually in a clinical center. For these cases, there is a lack of computer-based self-training tools for minimizing the psychosocial impact of hearing deficiency. To develop and evaluate a web-based auditory self-training system for adult and elderly users of hearing aids. Two modules were developed for the web system: an information module based on guidelines for using hearing aids; and an auditory training module presenting a sequence of training exercises for auditory abilities along the lines of the auditory skill steps within auditory processing. We built aweb system using PHP programming language and a MySQL database .from requirements surveyed through focus groups that were conducted by healthcare information technology experts. The web system was evaluated by speech therapists and hearing aid users. An initial sample of 150 patients at DSA/HRAC/USP was defined to apply the system with the inclusion criteria that: the individuals should be over the age of 25 years, presently have hearing impairment, be a hearing aid user, have a computer and have internet experience. They were divided into two groups: a control group (G1) and an experimental group (G2). These patients were evaluated clinically using the HHIE for adults and HHIA for elderly people, before and after system implementation. A third web group was formed with users who were invited through social networks for their opinions on using the system. A questionnaire evaluating hearing complaints was given to all three groups. The study hypothesis considered that G2 would present greater auditory perception, higher satisfaction and fewer complaints than G1 after the auditory training. It was expected that G3 would have fewer complaints regarding use and acceptance of the system. The web system, which was named SisTHA portal, was finalized, rated by experts and hearing aid users and approved for use. The system comprised auditory skills training along five lines: discrimination; recognition; comprehension and temporal sequencing; auditory closure; and cognitive-linguistic and communication strategies. Users needed to undergo auditory training over a minimum period of 1 month: 5 times a week for 30 minutes a day. Comparisons were made between G1 and G2 and web system use by G3. The web system developed was approved for release to hearing aid users. It is expected that the self-training will help improve effective use of hearing aids, thereby decreasing their rejection.

Performance on large-scale science tests: Item attributes that may impact achievement scores

NASA Astrophysics Data System (ADS)

Gordon, Janet Victoria

Significant differences in achievement among ethnic groups persist on the eighth-grade science Washington Assessment of Student Learning (WASL). The WASL measures academic performance in science using both scenario and stand-alone question types. Previous research suggests that presenting target items connected to an authentic context, like scenario question types, can increase science achievement scores especially in underrepresented groups and thus help to close the achievement gap. The purpose of this study was to identify significant differences in performance between gender and ethnic subgroups by question type on the 2005 eighth-grade science WASL. MANOVA and ANOVA were used to examine relationships between gender and ethnic subgroups as independent variables with achievement scores on scenario and stand-alone question types as dependent variables. MANOVA revealed no significant effects for gender, suggesting that the 2005 eighth-grade science WASL was gender neutral. However, there were significant effects for ethnicity. ANOVA revealed significant effects for ethnicity and ethnicity by gender interaction in both question types. Effect sizes were negligible for the ethnicity by gender interaction. Large effect sizes between ethnicities on scenario question types became moderate to small effect sizes on stand-alone question types. This indicates the score advantage the higher performing subgroups had over the lower performing subgroups was not as large on stand-alone question types compared to scenario question types. A further comparison examined performance on multiple-choice items only within both question types. Similar achievement patterns between ethnicities emerged; however, achievement patterns between genders changed in boys' favor. Scenario question types appeared to register differences between ethnic groups to a greater degree than stand-alone question types. These differences may be attributable to individual differences in cognition, characteristics of test items themselves and/or opportunities to learn. Suggestions for future research are made.

Annually, more than 127,000 people are killed and at least 2.4 million people injured in road accidents in Europe. Consequently, in half of all countries in the European Union a first aid and basic life support course has become mandatory for learner drivers. The aim of this study was to evaluate the effect of this course on participants' knowledge and self-assessed first aid and basic life support skills. Participants were given a questionnaire before and after course. In total, 115 participants (response rate 98%) were included in the study. Mean age was 20 years (46% female and 54% male). Out of 12 questions, the average number of correct answers increased from 5.6 before the course to 8.7 after the course (p < 0.001). Upon completion of the course, 95% or more of the participants knew how to prioritise treatment of several casualties, knew how to relieve a foreign body airway obstruction, and knew the recommended compression-ventilation ratio during CPR (p < 0.001 for all). Despite significant improvements after the course only 64% knew how to diagnose cardiac arrest, 44% knew when to activate an automatic external defibrillator and 23% were aware of when to activate the emergency medical services. Participants significantly increased their self-confidence in own skills after the course (p < 0.001). A mandatory course for learner drivers significantly improves participants' knowledge and their self-assessed skills in first aid and basic life support. However, improvements of the course should be considered on a number of key topics. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Probing the rapid dynamics of plasma evolution in laser-driven plasma interactions provides deeper understanding of experiments in the context of laser-driven ion acceleration and facilitates the interplay with complementing numerical investigations. Besides the microscopic scales involved, strong plasma (self-)emission, predominantly around the harmonics of the driver laser, often complicates the data analysis. We present the concept and the implementation of a stand-alone probe laser system that is temporally synchronized to the driver laser, providing probing wavelengths beyond the harmonics of the driver laser. The capability of this system is shown during a full-scale laser proton acceleration experiment using renewable cryogenic hydrogen jet targets. For further improvements, we studied the influence of probe color, observation angle of the probe and temporal contrast of the driver laser on the probe image quality.

Children with hearing loss are at risk for lower self-esteem due to differences from hearing peers relative to communication skills, physical appearance, and social maturity. This study examines the influence of generic factors unrelated to hearing loss (e.g., age, gender, temperament) and specific factors associated with hearing loss (e.g., age at identification, communication skills) on how children with hearing loss wearing cochlear implants or hearing aids appraise self-esteem. Fifty children with hearing loss wearing cochlear implants or hearing aids participated (Mean age: 12.88 years; mean duration of device use: 3.43 years). Participants independently completed online questionnaires to assess communication skills, social engagement, self-esteem, and temperament. Children with hearing loss rated global self-esteem significantly more positively than hearing peers, t = 2.38, p = .02. Self-esteem ratings attained significant positive correlations with affiliation (r = .42, p = .002) and attention (r = .45, p = .001) temperaments and a significant negative association with depressive mood (r = − .60, p < .0001). No significant correlations emerged between self-esteem and demographic factors, communication skills, or social engagement. Because successful communication abilities do not always co-occur with excellent quality of life, clinicians and professionals working with children with hearing loss need to understand components contributing to self-esteem to improve identification, counseling, and external referrals for children in this population.

The current study aimed to identify the sources of HIV prevention information for female sex workers in Beijing and assess the associations between levels of mass media exposure of HIV/AIDS prevention information and HIV/AIDS knowledge as well as condom use-related attitudes, beliefs, and behaviors. Cross-sectional data were collected from 359 female sex workers in Beijing, China. Chi-square tests and one-way ANOVA tests were employed. Female sex workers sampled in Beijing were more likely to obtain HIV/AIDS prevention information from television and street posters than radio and the Internet. However, a higher level of exposure to and a lasting impression on online information were significantly associated with a higher level of condom use self-efficacy and more consistent condom use among the participants. Exposure to HIV/AIDS prevention information delivered by radio, street posters, and the Internet was found to be associated with sexual communication about HIV or condom use with sexual partners. Overall, this study provides preliminary evidence of the utility of various mass media outlets in delivering HIV/AIDS prevention information among female sex workers in China. Future studies are needed to systematically examine the effectiveness of mass media-based prevention education on HIV/AIDS related attitudes and behaviors among female sex workers and other populations in China.

An Up-to-date Approach to a Patient with a Suspected Autoinflammatory Disease

Autoinflammatory diseases (AID) are characterized by seemingly unprovoked self-limited attacks of fever and systemic inflammation potentially leading to amyloidosis. Familial Mediterranean fever (FMF) is the most common AID and therefore the most studied. Besides FMF, the other main hereditary AID are tumor necrosis factor-associated periodic fever syndrome (TRAPS), mevalonate kinase deficiency (MKD), and cryopyrin-associated periodic fever syndrome (CAPS). These hereditary diseases result from a mutant gene that is involved in the regulation of inflammation, resulting in a characteristic clinical phenotype. The differential diagnosis of AID can be challenging due to a wide overlap in clinical manifestations. Moreover, a considerable proportion of patients present with autoinflammatory symptoms but without a pathogenetic variant on genetic analysis. Furthermore, non-hereditary AID, such as the periodic fever, aphthous stomatitis, pharyngitis, adenitis (PFAPA) syndrome, which is the most common AID in children worldwide, must be excluded in certain circumstances. Herein we shall review the main AID and describe a practical approach to diagnosis in a patient with a clinical suspicion of AID. PMID:28178435

The adequate knowledge required for handling an emergency without hospital setting at the site of the accident or emergency may not be sufficient as most medical schools do not have formal first aid training in the teaching curriculum. The aim of this study is to assess the level of knowledge of medical students in providing first aid care. This cross-sectional study was conducted during May 2011 among 152 medical students. Data was collected using a self-administered questionnaire. Based on the scores obtained in each condition requiring first aid, the overall knowledge was graded as good, moderate and poor. Only 11.2% (17/152) of the total student participants had previous exposure to first aid training. Good knowledge about first aid was observed in 13.8% (21/152), moderate knowledge in 68.4% (104/152) and poor knowledge in 17.8% (27/152) participants. Analysis of knowledge about first aid management in select conditions found that 21% (32/152) had poor knowledge regarding first aid management for shock and for gastro esophageal reflux disease and 20.4% (31/152) for epistaxis and foreign body in eyes. All students felt that first aid skills need to be taught from the school level onwards and all of them were willing to enroll in any formal first aid training sessions. The level of knowledge about first aid was not good among majority of the students. The study also identified the key areas in which first aid knowledge was lacking. There is thus a need for formal first aid training to be introduced in the medical curriculum.

The transmission and prevalence of Human Immunodeficiency Virus (HIV) among those employed as sex trade workers (STW) is a major public health concern. The present study describes the self-reported responses of 340 STW, at-risk for contracting HIV. The participants were recruited by selective targeting between 2009 and 2010 from within the Saskatoon Health Region (SHR), Saskatchewan, Canada. As of 2012, the SHR has the highest incidence rate of positive test reports for HIV in Canada, at more than three times the national average (17.0 vs. 5.9 per 100,000 people). Additionally, the epidemiology of HIV/AIDS in the SHR is different from that seen elsewhere in Canada (still mostly men having sex with men and Caucasians), with its new HIV cases predominantly associated with injection drug use and Aboriginal cultural status. The purpose of this study was to (a) describe the demographic and socio-economic characteristics of the STW in the SHR, (b) identify their significant life events, self-reported problems, knowledge, attitudes, behaviors, self-efficacy, and barriers regarding HIV, and (c) determine the significant independent risk indicators for STW self-reporting a chance of greater than 50% of becoming infected with HIV/AIDS. The majority of the study participants were females, who were never married, of Aboriginal descent, without a high school diploma, and had an annual income of less than $10,000. Using multivariate regression analysis, four significant independent risk indicators were associated with STW reporting a greater that 50% chance of acquiring HIV/AIDS, including experiencing sexual assault as a child, injecting drugs in the past four weeks, being homeless, and a previous Chlamydia diagnosis. These findings provide important evidence of the essential sexual and drug-related vulnerabilities associated with the risk of HIV infection among STW and offer insight into the design and implementation of effective and culturally sensitive public health intervention and prevention efforts. To be most effective, it is recommended that such intervention and prevention initiatives: (1) use specifically tailored community-based outreach to high risk STW who are drug users and link them with appropriate drug treatment and HIV/AIDS prevention and treatment services, (2) provide free and confidential, routine HIV counseling and testing in substance abuse programs, and (3) build capacity among the local, Aboriginal NGOs so as to address with cultural sensitivity both the drug and HIV-related risk factors prevalent among this vulnerable population.

Self-esteem and coping strategies among deaf students.

Research studies on the determinants of self-esteem of deaf individuals often yield inconsistent findings. The current study assessed the effects on self-esteem of factors related to deafness, such as the means of communication at home and severity of hearing loss with hearing aid, as well as the coping styles that deaf people adopt to cope with everyday life in a hearing world. Data were collected among the deaf students of California State University, Northridge. Hierarchical regression modeling showed that identification with the Deaf community significantly contributed to positive self-esteem. Results also revealed that deaf students with greater degree of hearing loss and with bicultural skills that help them function in both the hearing and the Deaf community generally have higher self-esteem. Implications for further study are discussed.

To compare acquired immune deficiency syndrome (AIDS) related knowledge, attitudes, behaviors and their influencing factors among college students in different years in Beijing, and to provide evidence for targeted health education among college students in future. College students were selected by the stratified cluster sampling method, and a questionnaire survey was conducted among college students in year 2006 and 2016 in Beijing. The sample sizes were 1 800 and 3 001 college students, respectively. The contents of the questionnaire included: socio-demographic characteristics, AIDS related knowledge, AIDS related attitude, sex intercourse and its related risk behaviors, condom use intension, and AIDS related health education. Compared with the year 2006, the average AIDS knowledge scores of college students in year 2016 dropped from 12.78±1.95 to 11.90±2.56 (t=12.91, P<0.05), and the correct answer rates of questions in the knowledge part were decreased, too. Except for belief on condom use, the college students were more negative on AIDS related attitude and self-efficacy in year 2016 than in year 2006. Among the students who had sex experience, the rates of commercial sex [17.65% (33/187) vs. 6.53% (16/245), χ 2 =13.003, P<0.001] and the rates of homo-sexual intercourse [15.43% (29/188) vs. 4.13% (10/242), χ 2 =16.356, P<0.001] were higher in year 2016 than in year 2006. The main way for the students seeking pornographic information was changed from books to internet (41.15%) in 2016 compared with the year 2016. In 2016, the influencing factors of intention on condom use were male (OR=0.713), self-efficacy of condom purchase (OR=0.876), never received sex education before college (OR=0.752), self-efficacy of condom use (OR=1.135), belief of condom use (OR=1.775), and attitude towards AIDS patients (OR=1.136). AIDS related knowledge, attitudes and behaviors among college students have been changed, AIDS related health education should be designed and improved based on new characteristics of college students. AIDS health education in colleges should pay more attention to sex attitude and sex responsibility and self-protection awareness among college students as well.

2005-03-01

An evaluation study of an undergraduate HIV/AIDS interprofessional education program for medical, nursing and pharmacy students was undertaken to assess changes in role perception, attitudes towards collaboration, self-reported teamwork skills and satisfaction with a shared learning experience. A combined one group pretest-posttest and time-series study design was used. Several survey instruments and observation checklists were completed by students and tutors before, during and after the educational program. Students reported greater awareness of roles and the continuous exposure to interprofessional learning led to improved attitudes towards teamwork. Standardized patients were effective in fostering an experience of realism and motivating collaboration between students. A problem-based learning approach combined with standardized patients was effective in enhancing HIV/AIDS interprofessional role perception, enhancing attitudes towards collaboration and interprofessional approaches to HIV/AIDS care and fostering confidence in teamwork skills among pre-licensure health sciences students.

Imagery rescripting as a stand-alone treatment for patients with social phobia: a case series.

PubMed

Frets, Petra G; Kevenaar, Ciska; van der Heiden, Colin

2014-03-01

The majority of patients with social phobia reports experiencing negative images, usually linked to memories of earlier aversive social experiences. Several studies have indicated that such negative self-imagery appears to have a causal role in maintaining social phobia, which suggests that interventions aimed at dealing with these images could be beneficial in the treatment of social phobia. One potentially powerful approach is imagery rescripting (IR), a clinical intervention that focuses on changing the meaning and impact of unpleasant memories. In the treatment of social phobia IR was only used as part of a broader cognitive-behavioral treatment package. However, we propose that IR alone might also be an effective treatment for this anxiety disorder. The present study reports an initial evaluation of the application of IR as a stand-alone treatment for six adult outpatients presenting with social phobia. A single case series using an A-B replication across patients design was employed. Following a no-treatment baseline period, IR was delivered weekly and patients were followed up for 3 and 6 months. For all patients, substantial reductions were obtained on all outcome measures at post-treatment, and gains were largely maintained at 6-months follow-up. The generalizability of the effects of IR for social phobia is limited by the small number of patients treated by only one therapist. The results of this preliminary case series suggest that IR as a stand alone treatment is an apparently effective intervention in the treatment of patients with social phobia, and indicate that controlled evaluation of its efficacy might be worthwhile.

A prospective single-surgeon nonrandomized clinical study. To evaluate the radiographic and clinical outcomes, by fixation type, in extreme lateral interbody fusion (XLIF) patients and provide an algorithm for determining patients suitable for stand-alone XLIF. XLIF may be supplemented with pedicle screw fixation, however, since stabilizing structures remain intact, it is suggested that stand-alone XLIF can be used for certain indications. This eliminates the associated morbidity, though subsidence rates may be elevated, potentially minimizing the clinical benefits. A fixation algorithm was developed after evaluation of patient outcomes from the surgeon's first 30 cases. This algorithm was used prospectively for 40 subsequent patients to determine the requirement for supplemental fixation. Preoperative, postoperative, and 12-month follow-up computed tomography scans were measured for segmental and global lumbar lordosis and posterior disk height. Clinical outcome measures included back and leg pain (visual analogue scale), Oswestry Disability Index (ODI), and SF-36 physical and mental component scores (PCS and MCS). Preoperatively to 12-month follow-up there were increases in segmental lordosis (7.9-9.4 degrees, P=0.0497), lumbar lordosis (48.8-55.2 degrees, P=0.0328), and disk height (3.7-5.5 mm, P=0.0018); there were also improvements in back (58.6%) and leg pain (60.0%), ODI (44.4%), PCS (56.7%), and MCS (16.1%) for stand-alone XLIF. For instrumented XLIF, segmental lordosis (7.6-10.5 degrees, P=0.0120) and disk height (3.5-5.6 mm, P<0.001) increased, while lumbar lordosis decreased (51.1-45.8 degrees, P=0.2560). Back (49.8%) and leg pain (30.8%), ODI (32.3%), PCS (37.4%), and MCS (2.0%) were all improved. Subsidence occurred in 3 (7.5%) stand-alone patients. The XLIF treatment fixation algorithm provided a clinical pathway to select suitable patients for stand-alone XLIF. These patients achieved positive clinical outcomes, satisfactory fusion rates, with sustained correction of lordosis and restoration of disk height.

Hearing and vision problems are common in older adults. We investigated the association of self-reported sensory impairment with lifestyle factors, chronic conditions, physical functioning, quality of life and social interaction. A population-based cross-sectional study of participants of the British Regional Heart Study aged 63-85 years. A total of 3981 men (82% response rate) provided data. Twenty-seven per cent (n = 1074) reported hearing impairment including being able to hear with aid (n = 482), being unable to hear (no aid) (n = 424) and being unable to hear despite aid (n = 168). Three per cent (n = 124) reported vision impairment. Not being able to hear, irrespective of use of hearing aid, was associated with poor quality of life, poor social interaction and poor physical functioning. Men who could not hear despite hearing aid were more likely to report coronary heart disease (CHD) [age-adjusted odds ratios (ORs) 1.89 (95% confidence interval 1.36-2.63)]. Vision impairment was associated with symptoms of CHD including breathlessness [OR 2.06 (1.38-3.06)] and chest pain [OR 1.58 (1.07-2.35)]. Vision impairment was also associated with poor quality of life, poor social interaction and poor physical functioning. Sensory impairment is associated with poor physical functioning, poor health and poor social interaction in older men. Further research is warranted on pathways underlying these associations. © The Author 2015. Published by Oxford University Press on behalf of Faculty of Public Health. All rights reserved.

2017-01-01

This study aimed to determine the predictors of entering a hearing aid evaluation period (HAEP) using a prospective design drawing on the health belief model and the transtheoretical model. In total, 377 older persons who presented with hearing problems to an Ear, Nose, and Throat specialist (n = 110) or a hearing aid dispenser (n = 267) filled in a baseline questionnaire. After 4 months, it was determined via a telephone interview whether or not participants had decided to enter a HAEP. Multivariable logistic regression analyses were applied to determine which baseline variables predicted HAEP status. A priori, candidate predictors were divided into ‘likely’ and ‘novel’ predictors based on the literature. The following variables turned out to be significant predictors: more expected hearing aid benefits, greater social pressure, and greater self-reported hearing disability. In addition, greater hearing loss severity and stigma were predictors in women but not in men. Of note, the predictive effect of self-reported hearing disability was modified by readiness such that with higher readiness, the positive predictive effect became stronger. None of the ‘novel’ predictors added significant predictive value. The results support the notion that predictors of hearing aid uptake are also predictive of entering a HAEP. This study shows that some of these predictors appear to be gender specific or are dependent on a person’s readiness for change. After assuring the external validity of the predictors, an important next step would be to develop prediction rules for use in clinical practice, so that older persons’ hearing help-seeking journey can be facilitated.

To evaluate the effects of health education on HIV/AIDS high-risk behaviors, knowledge, and attitude among floating population in China. A computerized literature searching was carried out in Chinese Biomedical Database, Chinese National Knowledge Infrastructure, Wan Fang and VIP databases to collect articles published in China between 2005 and 2010. Words as "AIDS", "Floating Population", "Intervention", "Health Education", "High-risk Behavior" were used. Type of studies would include "self-control intervention studies or studies containing sections of self-control intervention". Meta-analyses were performed to assess 8 outcomes which targeting on high-risk behavior, knowledge and attitudes of AIDS. RevMan 4.2 software was used to analyze the intervention effects for these indexes. After the interventions, the rate on awareness of "Whether condoms can reduce the HIV/AIDS infection risk" increased by 23% [rate difference (RD) 95%CI: 0.19, 0.27] and "Whether keeping monogamous sexual relationship can reduce the risk of infection" increased by 18% (RD 95%CI: 0.14, 0.23). The proportion of "Willing to use condoms in sexual life" increased by 16% (RD 95%CI: 0.11, 0.22); and "The incidence of commercial sex behaviors" reduced by 6% (RD 95%CI: -0.11, -0.02). "The Ratio of condom use during commercial sex behaviors" increased by 17% (RD 95%CI: 0.10, 0.23). and "Recent use of condoms during sex" increased by 25% (RD 95%CI: 0.15, 0.35). All the data showed significant differences (P < 0.01), respectively. After health education, great improvements were found for HIV-related sexual knowledge, attitudes, and behaviors among the floating population.

The purpose of this study was to examine the retention of wilderness first aid (WFA) knowledge, self-efficacy beliefs, and skills over time in a sample of WFA course participants. Seventy-two open enrollment (volunteer) WFA course participants were assessed at 4 months, 8 months, or 12 months after training. Changes in WFA knowledge and self-efficacy were assessed by written instruments after the course and at the follow-up interval (4, 8, or 12 months). The WFA skills were assessed by a scored medical scenario at the follow-up interval. As the time interval increased, WFA knowledge, self-efficacy, and skill proficiency decreased. The WFA knowledge and self-efficacy beliefs were not highly correlated with skill performance. Without additional training, regular use of the course content, or efforts to refresh thinking on key topics, the ability of WFA students to effectively apply their learning will likely decrease as time from training increases. With respect to these WFA courses, student scores on written tests did not accurately reflect competence in performing practical skills related to a medical scenario. In addition, student self-confidence in the ability to perform such skills did not strongly correlate with actual skills and ability. Copyright © 2012 Wilderness Medical Society.

Clinical guidelines recommend a personalized approach to mammography screening for women in their forties; however, methods to do so are lacking. An evidence-based mammography screening decision aid was developed as an electronic mobile application and evaluated in a before-after study. The decision aid (Mammopad) included modules on breast cancer, mammography, risk assessment, and priority setting about screening. Women aged 40-49 years who were patients of rural primary care clinics, had no major risk factors for breast cancer, and no mammography during the previous year were invited to use the decision aid. Twenty women participated in pretesting of the decision aid and 75 additional women completed the before-after study. The primary outcome was decisional conflict measured before and after using Mammopad. Secondary outcomes included decision self-efficacy and intention to begin or continue mammography screening. Differences comparing measures before versus after use were determined using Wilcoxon signed rank tests. After using Mammopad, women reported reduced decisional conflict based on mean Decisional Conflict Scale scores overall (46.33 versus 8.33; Z = -7.225; p < 0.001) and on all subscales (p < 0.001). Women also reported increased mean Decision Self-Efficacy Scale scores (79.67 versus 95.73; Z = 6.816, p < 0.001). Although 19% of women changed their screening intentions, this was not statistically significant. Women reported less conflict about their decisions for mammography screening, and felt more confident to make decisions after using Mammopad. This approach may help guide women through the decision making process to determine personalized screening choices that are appropriate for them.

To avoid complications associated with plating in anterior cervical discectomy and fusion (ACDF), stand-alone anchored PEEK cage was developed and favourable outcomes with a low rate of dysphasia have been described. The objective of this study was to compare the clinical and radiological outcomes of ACDF using a standalone anchored PEEK cage (PREVAIL; Medtronic Sofamor Danek, Memphis, TN) with those of a PEEK cage with plating in a prospective randomized manner. Fifty patients with single-level cervical radiculopathy were randomly assigned to a PREVAIL or a PEEK cage with plating. Following 3, 6, 12, and 24 months, clinical and radiological outcomes were assessed. The mean surgical time for the patients with a PREVAIL was significantly shorter than that for those with a PEEK cage with plating. The clinical outcomes evaluated by visual analogue scale for pain and the Odom's criteria were comparable between both the groups. Both the groups demonstrated the high fusion rate (92% in PREVAIL; 96% in PEEK cage with plating). The subsidence rate and the improvement of cervical alignment were comparable between both the groups. The incidence of adjacent-level ossification was significantly lower for patients with a PREVAIL than that for those with a PEEK cage with plating. The rate of dysphasia graded by the method of Bazaz and measurement of prevertebral soft tissue swelling indicated no significant differences between both the groups. Our prospective randomized study confirmed that stand-alone anchored PEEK cage is a valid alternative to plating in ACDF with a low rate of adjacent-level ossification. However, the potential to reduce the incidence of dysphasia was not confirmed.

Objectives: This descriptive summary of the literature provides an overview of the available studies (published between January 1980 and January 2009) on correlates of help-seeking behavior for hearing loss, hearing-aid uptake, hearing-aid use, and satisfaction with the device. Methods: Publications were identified by structured searches in Pubmed and Cinahl and by inspecting the reference lists of relevant articles. The articles covered different stages that a person with hearing impairment may go through: prior to hearing aid fitting, the period covering the fitting and the period post hearing aid fitting. Inclusion of articles occurred according to strict inclusion and exclusion criteria. Data were extracted by two independent researchers. Thirty-nine papers were included that identified 31 factors examined in relation to the four outcome measures. These covered personal factors (e.g., source of motivation, expectation, attitude), demographic factors (e.g., age, gender) and external factors (e.g., cost, counseling). Only two studies covered the actual fitting process. There was only one factor positively affecting all four outcome variables. This was self-reported hearing disability. The vast majority of studies showed no relationship of age and gender with any of the outcome domains. Discussion and conclusion: Whereas research of the last 28 years yielded valuable information regarding relevant and irrelevant factors in hearing aid health care, there are still many relevant issues that have never been investigated in controlled studies. These are discussed. PMID:21109549

School-based HIV/AIDS education is a common and well-proven intervention strategy for providing information on HIV/AIDS to young people. However, lack of skills among teachers for imparting sensitive information to students can lead to programme failure in terms of achieving goals. A cross-sectional study was conducted among teachers to identify the factors that support or hinder their role in HIV/AIDS education. A self-administered questionnaire was used for interviewing teachers from randomly-selected schools in two adjacent districts in Bangladesh. Based on exposure to teachers' training, the districts were divided into control and intervention areas and the teachers' ability, skill, and their participation in HIV/AIDS education were compared between the districts. Trained teachers in the intervention schools were more likely to participate, less likely to face difficulties, and more likely to use interactive teaching methods in HIV/ AIDS classes compared to the controls who did not receive any training. Inadequate allocation of time for conducting the HIV/AIDS class was found to be barriers to HIV/AIDS education that suggest the need to provide teachers with more support in terms of training and logistics.

Objectives This study assessed the knowledge of recommended urinary catheter care practices among nursing home (NH) healthcare workers (HCWs) in Southeast Michigan. Design A self-administered survey. Setting Seven nursing homes in Southeast Michigan. Participants Three hundred and fifty-six healthcare workers. Methods An anonymous, self-administered survey of HCWs (nurses & nurse aides) in seven NHs in 2006. The survey included questions about respondent characteristics and knowledge about indications, care, and personal hygiene pertaining to urinary catheters. The association of knowledge measures with occupation (nurses vs. aides) was assessed using generalized estimating equations. Results A total of 356 of 440 HCWs (81%) responded. Over 90% of HCWs were aware of measures such as cleaning around the catheter daily, glove use, and hand hygiene with catheter manipulation. They were less aware of research-proven recommendations of not disconnecting the catheter from its bag (59% nurses vs. 30% aides, P < .001), not routinely irrigating the catheter (48% nurses vs. 8% aides, P < .001), and hand hygiene even after casual contact (60% nurses vs. 69% aides, P = .07). HCWs were also unaware of recommendations regarding alcohol-based handrub (27% nurses & 32% aides with correct responses, P = .38). HCWs reported sources, both informal (such as nurse supervisors) and formal (in-services), of knowledge about catheter care. Conclusion Wide discrepancies remain between research-proven recommendations pertaining to urinary catheter care and HCWs' knowledge. Nurses and aides differ in their knowledge of recommendations against harmful practices, such as disconnecting the catheter from the bag and routinely irrigating catheters. Further research should focus on strategies to enhance dissemination of proven infection control practices in NHs. PMID:20662957

The aim of this study was to determine the prevalence of use of hearing aids by older adults in Chile and the influence of some variables such as education level, income level and geographic area of residence on the prevalence of hearing aids. A national cross-sectional survey which was carried out in 2009. A representative sample of 4766 Chilean older adults aged 60 years and above. The percentage of older adults in Chile who self-reported hearing problems and used hearing aids was 8.9%. Such prevalence increased for adults living in urban areas and for those who knew about the new Chilean programme of universal access to health services (AUGE). For older adults who did not know about this programme, significant associations between the use of hearing aids and the variables of age, geographic area of residence, and income level were found. People's knowledge about AUGE programme may positively influence the use of hearing aids, although a direct effect cannot be attributed.

Development of a low cost test rig for standalone WECS subject to electrical faults.

PubMed

Himani; Dahiya, Ratna

2016-11-01

In this paper, a contribution to the development of low-cost wind turbine (WT) test rig for stator fault diagnosis of wind turbine generator is proposed. The test rig is developed using a 2.5kW, 1750 RPM DC motor coupled to a 1.5kW, 1500 RPM self-excited induction generator interfaced with a WT mathematical model in LabVIEW. The performance of the test rig is benchmarked with already proven wind turbine test rigs. In order to detect the stator faults using non-stationary signals in self-excited induction generator, an online fault diagnostic technique of DWT-based multi-resolution analysis is proposed. It has been experimentally proven that for varying wind conditions wavelet decomposition allows good differentiation between faulty and healthy conditions leading to an effective diagnostic procedure for wind turbine condition monitoring.

An Overview of a Trajectory-Based Solution for En Route and Terminal Area Self-Spacing: Fifth Edition

NASA Technical Reports Server (NTRS)

Abbott, Terence S.

2015-01-01

This paper presents an overview of the fifth revision to an algorithm specifically designed to support NASA's Airborne Precision Spacing concept. This algorithm is referred to as the Airborne Spacing for Terminal Arrival Routes version 12 (ASTAR12). This airborne self-spacing concept is trajectory-based, allowing for spacing operations prior to the aircraft being on a common path. Because this algorithm is trajectory-based, it also has the inherent ability to support required-time-of- arrival (RTA) operations. This algorithm was also designed specifically to support a standalone, non-integrated implementation in the spacing aircraft. This current revision to the algorithm includes a ground speed feedback term to compensate for slower than expected traffic aircraft speeds based on the accepted air traffic control tendency to slow aircraft below the nominal arrival speeds when they are farther from the airport.

The present study aims at developing and assessing an assistive tool for operating electronic devices at home by means of a P300-based brain-computer interface (BCI). Fifteen severely impaired subjects participated in the study. The developed tool allows users to interact with their usual environment fulfilling their main needs. It allows for navigation through ten menus and to manage up to 113 control commands from eight electronic devices. Ten out of the fifteen subjects were able to operate the proposed tool with accuracy above 77 %. Eight out of them reached accuracies higher than 95 %. Moreover, bitrates up to 20.1 bit/min were achieved. The novelty of this study lies in the use of an environment control application in a real scenario: real devices managed by potential BCI end-users. Although impaired users might not be able to set up this system without aid of others, this study takes a significant step to evaluate the degree to which such populations could eventually operate a stand-alone system. Our results suggest that neither the type nor the degree of disability is a relevant issue to suitably operate a P300-based BCI. Hence, it could be useful to assist disabled people at home improving their personal autonomy.

A computer-aided detection (CAD) system with a 3D algorithm for small acute intracranial hemorrhage

2012-02-01

Acute Intracranial hemorrhage (AIH) requires urgent diagnosis in the emergency setting to mitigate eventual sequelae. However, experienced radiologists may not always be available to make a timely diagnosis. This is especially true for small AIH, defined as lesion smaller than 10 mm in size. A computer-aided detection (CAD) system for the detection of small AIH would facilitate timely diagnosis. A previously developed 2D algorithm shows high false positive rates in the evaluation based on LAC/USC cases, due to the limitation of setting up correct coordinate system for the knowledge-based classification system. To achieve a higher sensitivity and specificity, a new 3D algorithm is developed. The algorithm utilizes a top-hat transformation and dynamic threshold map to detect small AIH lesions. Several key structures of brain are detected and are used to set up a 3D anatomical coordinate system. A rule-based classification of the lesion detected is applied based on the anatomical coordinate system. For convenient evaluation in clinical environment, the CAD module is integrated with a stand-alone system. The CAD is evaluated by small AIH cases and matched normal collected in LAC/USC. The result of 3D CAD and the previous 2D CAD has been compared.

A computer-operated binocular vision testing device was developed as one part of a system designed for NASA to evaluate the visual function of astronauts during spaceflight. This particular device, called the Mark 3 Haploscope, employs semi-automated psychophysical test procedures to measure visual acuity, stereopsis, phoria, fixation disparity, refractive state and accommodation/convergence relationships. Test procedures are self-administered and can be used repeatedly without subject memorization. The Haploscope was designed as one module of the complete NASA Vision Testing System. However, it is capable of stand-alone operation. Moreover, the compactness and portability of the Haploscope make possible its use in a broad variety of testing environments.

Injuries are very common and can occur at any point of time in a day. Unintended injuries in kindergarten children are the most common and need immediate life saving care which is known as first aid. This study aimed to investigate knowledge, attitude, practice, and associated factors of first aid among kindergarten teachers of Lideta sub-city Addis Ababa, Ethiopia. A cross-sectional study was conducted among kindergarten teachers. Data was collected using pretested, structured and self-administered questionnaire S1 File. The collected data was entered in to Epi Data version 3.1 software and analyzed using SPSS version 20. Logistic regression analysis was used to identify association between kindergarten teachers' knowledge and attitudes towards first aid and different variables. Odds ratios with 95% CI and p<0.05 were computed to determine the presence of the association. One hundred and ninety-four teachers participated in the study with a response rate of 95%. Only 40% of the teachers were knowledgeable and 75% of them had positive attitude for first aid. Eighty percent of teachers encountered with children in need of first aid. Kindergarten teachers older than 35 years [AOR = 4.2, 95%CI: (1.02, 16.9)], five years' experience [AOR = 3.1, 95%CI: (1.2, 7.6)], having previous first aid training [AOR = 3.1, 95%CI: (1.2, 7.7)], source of first aid information and teachers serving in private kindergarten are associated with having knowledge of first aid. Long time experience, type of kindergarten, previous training, and exposure to children in need of first aid were positive association with attitude towards first aid. Low first aid knowledge and high positive attitude among kindergarten teachers. Having long time experience, being older age, previous first aid training, and serving in private kindergarten were positively associated with first aid knowledge and positive attitude. Creating awareness and including first aid courses in the kindergarten teachers' curriculum need to be considered.

Teaching wilderness first aid in a remote First Nations community: the story of the Sachigo Lake Wilderness Emergency Response Education Initiative.

To understand how community members of a remote First Nations community respond to an emergency first aid education programme. A qualitative study involving focus groups and participant observation as part of a community-based participatory research project, which involved the development and implementation of a wilderness first aid course in collaboration with the community. Twenty community members participated in the course and agreed to be part of the research focus groups. Three community research partners validated and reviewed the data collected from this process. These data were coded and analysed using open coding. Community members responded to the course in ways related to their past experiences with injury and first aid, both as individuals and as members of the community. Feelings of confidence and self-efficacy related access to care and treatment of injury surfaced during the course. Findings also highlighted how the context of the remote First Nations community influenced the delivery and development of course materials. Developing and delivering a first aid course in a remote community requires sensitivity towards the response of participants to the course, as well as the context in which it is being delivered. Employing collaborative approaches to teaching first aid can aim to address these unique needs. Though delivery of a first response training programme in a small remote community will probably not impact the morbidity and mortality associated with injury, it has the potential to impact community self-efficacy and confidence when responding to an emergency situation.

Navigating the AIDS industry: being poor and positive in Tanzania.

PubMed

Boesten, Jelke

2011-01-01

This article shows how poor people living with HIV/AIDS in Tanzania navigate a myriad of actors, agencies and organizations to obtain the aid they need to survive. It focuses on community-based organizations which establish networks of care through which people obtain care, treatment and financial support. A case study of a roadside town in Tanzania illustrates that these community-based networks of care — essential to the survival of many — are partly the product of the AIDS industry, which encourages the establishment of community-based organizations and voluntary service delivery rather than more formalized systems of care. Community-based organizations, however, are so poorly supported that they often deploy self-destructive strategies. The need to strategically navigate the AIDS industry creates tension and even conflict among HIV-positive activists, the people they represent and the wider community, which undermines rather than strengthens community-based interventions. Whilst the AIDS industry promises inclusion of HIV-positive people in the response to HIV/AIDS, it succeeds only partially, with the result that it may potentially do more harm than good.

Up to a quarter of the adults who own hearing aids never use them. To provide these 'non-users' with the best help, hearing care professionals need to have an in-depth understanding of the non-users' beliefs and feelings with regard to the non-use. This qualitative study explored these beliefs and feelings in order to increase our understanding of hearing aid non-users. Individual face-to-face semi-structured interviews were completed. Eleven hearing aid owners (aged 54-80 years) who reported that they never or hardly ever used their hearing aids. The participants expressed a variety of feelings towards their non-use, including indifference, self-annoyance, frustration, powerlessness, shame, and guilt. Their feelings were related to beliefs about: (1) the severity of their hearing handicap with and without hearing aids, (2) whom or what was responsible for the non-use, and (3) the attitudes of significant others towards the non-use. Hearing-aid non-users differ in their beliefs and feelings towards the non-use. A patient-centred approach is needed.

'Ted' (Trace editor) is a graphical editor for sequence and trace data from automated fluorescence sequencing machines. It provides facilities for viewing sequence and trace data (in top or bottom strand orientation), for editing the base sequence, for automated or manual trimming of the head (vector) and tail (uncertain data) from the sequence, for vertical and horizontal trace scaling, for keeping a history of sequence editing, and for output of the edited sequence. Ted has been used extensively in the C.elegans genome sequencing project, both as a stand-alone program and integrated into the Staden sequence assembly package, and has greatly aided in the efficiency and accuracy of sequence editing. It runs in the X windows environment on Sun workstations and is available from the authors. Ted currently supports sequence and trace data from the ABI 373A and Pharmacia A.L.F. sequencers.

To examine the relation of patient beliefs about medication usage and adherence to zidovudine (ZDV) therapy in persons with AIDS. Face-to-face interviews were used to determine attitudes of persons with AIDS toward ZDV and other prescribed medications, history of ZDV usage, and sociodemographics. A public hospital infectious disease clinic, an AIDS day care program, and an inpatient unit in a voluntary hospital where care was provided cooperatively by staff and an informal-care partner. One hundred forty-one people with the acquired immunodeficiency syndrome agreed to be reinterviewed as part of a longitudinal, New York City-based study examining outcomes related to quality of life. Initial recruitment procedures were to approach all active AIDS patients at each of the three sites between January and July of 1992: reinterviews, which were conducted an average of 6 months later, occurred from mid-1992 through May of 1993. The Zidovudine Drug Attitude Inventory was used to assess subjective feelings and attitudes concerning ZDV and prescribed medications in general. Respondents were grouped into five categories on the basis of their ZDV usage history: (1) "short-term" users (i.e., those who had been taking ZDV for 25 months or less); (2) "long-term" users (i.e., those who had been taking ZDV for more than 25 months); (3) self-terminated users; (4) doctor-terminated users; and (5) never users. Long-term users were likely to view ZDV as an illness prophylactic. In contrast, self-terminated users and never users were most likely to believe that ZDV caused adverse side effects and that medicine need not be taken as prescribed. Patients' beliefs about ZDV were significantly associated with adherence-related behavior. In particular, those who had self-terminated ZDV treatment believed that taking the drug was harmful, were skeptical of its ability to prevent illness, and felt that physician's directives about medication usage in general could be disregarded. These findings highlight the importance of educating patients about ZDV and of establishing regular patient-clinician exchanges concerning patient's experience with and beliefs concerning ZDV.

Objective We examined the association between methamphetamine (meth) use and dental problems in a large sample of HIV-positive adults. Methods We gathered data from 2,178 interviews across 14 sites of the U.S. Health Resources and Services Administration HIV/AIDS Bureau's Special Projects of National Significance Innovations in Oral Health Care Initiative from May 2007 to August 2010. We used multivariate generalized estimating equations to test the association between meth use and dental problems, adjusting for potential confounders. Results Past and current meth use was significantly associated with more dental problems. The study also found that poor self-reported mental health status, fewer years since testing positive for HIV, a history of forgoing dental care, less frequent teeth brushing, poor self-reported oral health status, oral pain, grinding or clenching teeth, some alcohol use, more years of education, and self-reported men-who-have-sex-with-men HIV risk exposure (compared with other exposure routes) were significantly associated with dental problems. Conclusion Individuals who are HIV-positive with a history of meth use experience access barriers to oral health care and more dental problems. Our study demonstrated that it is possible to recruit this population into dental care. Findings suggest that predisposing, enabling, and need factors can serve as demographic, clinical, and behavioral markers for recruiting people living with HIV/AIDS into oral health programs that can mitigate dental problems.

Rescripting Memory, Redefining the Self: A Meta-Emotional Perspective on the Hypothesized Mechanism(s) of Imagery Rescripting.

PubMed

Mancini, Alessandra; Mancini, Francesco

2018-01-01

Imagery Rescripting (ImRs) is a therapeutic technique that aims to reduce the distress associated with negative memories of early aversive experiences. It consists of prompting patients to rescript the autobiographical memory in line with their unmet needs. In recent years, ImRs was found effective in reducing symptoms of disorders such as depression, social phobia, obsessive-compulsive disorder, post-traumatic stress disorder, and personality disorders. However, the cognitive mechanisms underlying such broad effectiveness are currently an object of debate. Empirical evidence has shown that ImRs reduces the negative self-belief derived from aversive memories in different types of mental disorders. However, existing accounts are not very accurate in explaining how this change in self-belief occurs and therefore why ImRs is effective across psychopathologies. We propose that ImRs changes the semantic self-representation encapsulated in the aversive memory by reducing the meta-emotional problem (i.e., perceiving a negative emotion as problematic and unacceptable). Empirical evidence implicates the meta-emotional problem or "secondary problem" in the maintenance of different disorders and has shown that treating it leads to symptoms reduction. Here we hypothesize that: (i) ImRs as a stand-alone treatment may lead to a reduction of symptoms; negative self-belief and the meta-emotional problem; and (ii) the reduction of the meta-emotional problem might mediate the relation between symptoms and negative self-belief reduction. To test our hypothesis, we present an experimental procedure that could be used in future studies. We conclude discussing the existing theoretical frameworks that attempt to unravel the mechanisms that play a role in ImRs.

The stand-alone treatment of degenerative cervical spine pathologies is a proven method in clinical practice. However, its impact on subsidence, the resulting changes to the profile of the cervical spine and the possible influence of clinical results compared to treatment with additive plate osteosynthesis remain under discussion until present. This study was designed as a retrospective observational cohort study to test the hypothesis that radiographic subsidence of cervical cages is not associated with adverse clinical outcomes. 33 cervical segments were treated surgically by ACDF with stand-alone cage in 17 patients (11 female, 6 male), mean age 56 years (33-82 years), and re-examined after eight and twenty-six months (mean) by means of radiology and score assessment (Medical Outcomes Study Short Form (MOS-SF 36), Oswestry Neck Disability Index (ONDI), painDETECT questionnaire and the visual analogue scale (VAS)). Subsidence was observed in 50.5% of segments (18/33) and 70.6% of patients (12/17). 36.3% of cases of subsidence (12/33) were observed after eight months during mean time of follow-up 1. After 26 months during mean time of follow-up 2, full radiographic fusion was seen in 100%. MOS-SF 36, ONDI and VAS did not show any significant difference between cases with and without subsidence in the two-sample t-test. Only in one type of scoring (painDETECT questionnaire) did a statistically significant difference in t-Test emerge between the two groups (p = 0.03; α = 0.05). However, preoperative painDETECT score differ significantly between patients with subsidence (13.3 falling to 12.6) and patients without subsidence (7.8 dropped to 6.3). The radiological findings indicated 100% healing after stand-alone treatment with ACDF. Subsidence occurred in 50% of the segments treated. No impact on the clinical results was detected in the medium-term study period.

The purpose of this preliminary study was to assess the HIV/AIDS prevention needs, services, and resources in Liberia, including the readiness of local providers to conduct HIV/AIDS-related prevention programs based on a set of six key dimensions (prevention needs, knowledge, leadership, environment, risky behaviors, and resources). A valid self-administered qualitative-based health survey, based on a community readiness model, was utilized as the primary data collection source. A cross-sectional design that utilized a convenient sample of key informants such as health coordinators, program directors, and health administrator from both public and private HIV/AIDS-based organizations was used. Furthermore, an extensive review of the National Library of Medicine database of published articles from mid-1980 to 2002 was simultaneously conducted to gauge the extent of scientific publications on HIV/AIDS-related prevention services in Liberia. The findings from this study strongly suggest that Liberia is in a stage of vague awareness, as defined by the Tri-Ethnic Center community readiness framework, regarding HIV/AIDS-related activities, including a significant lack of HIV/AIDS-related resources and scientific publications. Accordingly, there is a critical need to acquire adequate resources and build capacity to implement effective HIV/AIDS-related prevention programming services in order to avert the negative public health consequences associated with HIV/AIDS, including the implementation of relevant evaluation and dissemination strategies. Most importantly, this model has the potential to be utilized in other resource-constraint settings, especially in the developing world, to assess prevention-related resources and programmatic readiness. This is the first published study to evaluate Liberia's HIV/AIDS prevention resources and to systematically document the extent and magnitude of the HIV/AIDS crises in the country.

Human immunodeficiency virus infection is a global crisis that represents a serious health threat, particularly among younger people. Various studies show that both orphan and non-orphan adolescents and youths experience vulnerability to HIV. Nevertheless, the findings hitherto are mixed and inconclusive. The aim of this study, therefore, was to assess the prevalence of parental death and its association with multiple sexual partners among secondary school students for evidence based interventions. A cross-sectional study was conducted among secondary school youth in Addis Ababa, Ethiopia. A multistage sampling technique was used to select a representative sample of 2,169 school youths. Sexual health behavior related data were collected using self-administered questionnaire. Binary logistic regression was employed to examine the relation between parental death and multiple sexual partners. Among the 2,169 eligible study participants 1948 (90%) completed the self-administered questionnaires. Of those 1,182(60.7%) were females. The overall prevalence of parental death was 347(17.8%.) with 95% CI (16.2%, 19.6%). The HIV/AIDS proportionate mortality ratio was 28% (97/347).A multivariate logistic regression analysis showed that high HIV/AIDS related knowledge (AOR = 0.39; 95% CI, 0.18-0.84), positive attitude towards HIV prevention methods (AOR = 0.48; 95% CI, 0.23-0.97), being tested for HIV (AOR = 0.52; 95% CI, 0.31-0.87) and chewing Khat (AOR = 2.59; 95% CI,1.28-5.26)] were significantly associated with having multiple sexual partners among secondary school youths. Significant proportion of secondary school youths had lost at least one parent due to various causes. High knowledge of HIV/AIDS, positive attitude towards 'ABC' rules for HIV prevention, being tested for HIV and chewing khat are more likely to be factors associated with multiple sexual partnership among secondary school students in Addis Ababa.Therefore, the school based interventions against the HIV/AIDS epidemic should be strengthened with particular emphasis on the effects of HIV/AIDS related knowledge, attitude towards preventive measures, mechanisms for improving HIV Counseling and Testing coverage and the associated prevailing risk factors.

The Relationship of Gender and Self-Efficacy on Social Physique Anxiety among College Students.

PubMed

Rothberger, Sara M; Harris, Brandonn S; Czech, Daniel R; Melton, Bridget

The anxiety or fear associated with physique evaluation is defined as Social Physique Anxiety (SPA). Numerous studies have examined this construct, yet a gap exists exploring this phenomenon among current college students with SPA, self-efficacy, and gender concurrently. Therefore, the purposes of this study included quantitatively analyzing the association between SPA, gender, and self-efficacy. Participants included 237 students at a Southeastern university participating in jogging, body conditioning, or weight training courses. Analysis of Variance yielded a significant main effect for self-efficacy as well, as those with lower self-efficacy displayed higher levels of SPA ( p < 0.001). Stepwise regression analysis indicated self-efficacy and gender were both significant predictors of SPA. This information could aid in creating interventions designed to decrease the prevalence of SPA and increase levels of self-efficacy among the current college student population.

It has been shown that DNA demethylation plays a pivotal role in the generation of induced pluripotent stem (iPS) cells. However, the underlying mechanism of this action is still unclear. Previous reports indicated that activation-induced cytidine deaminase (Aid, also known as Aicda) is involved in DNA demethylation in several developmental processes, as well as cell fusion-mediated reprogramming. Based on these reports, we hypothesized that Aid may be involved in the DNA demethylation that occurs during the generation of iPS cells. In this study, we examined the function of Aid in iPS cell generation using Aid knockout (Aid −/−) mice expressing a GFP reporter under the control of a pluripotent stem cell marker, Nanog. By introducing Oct3/4, Sox2, Klf4 and c-Myc, Nanog-GFP-positive iPS cells could be generated from the fibroblasts and primary B cells of Aid −/− mice. Their induction efficiency was similar to that of wild-type (Aid +/+) iPS cells. The Aid −/− iPS cells showed normal proliferation and gave rise to chimeras, indicating their capacity for self-renewal and pluripotency. A comprehensive DNA methylation analysis showed only a few differences between Aid +/+ and Aid −/− iPS cells. These data suggest that Aid does not have crucial functions in DNA demethylation during iPS cell generation. PMID:24718089

Research has consistently shown the benefits of regular physical activity (PA) for women living with HIV and AIDS (WLWHA). This study is a pilot, randomised controlled crossover trial, reporting the effects of a contextualised PA intervention amongst a sample of 21 HIV positive Xhosa-speaking women of low socioeconomic status (SES). The study determined total moderate-to-vigorous PA (TMVPA) as measured subjectively by the Global Physical Activity Questionnaire (GPAQ), total weekly steps (TWS) as measured by a pedometer, and self-efficacy for PA as measured by the Physical Exercise Self-efficacy scale (PESES). Multivariate analysis of covariance (MANCOVA) was used to compute the impact of the intervention on TMVPA, TWS, and self-efficacy for PA from baseline to six weeks, and baseline to 12 weeks post-intervention controlling for pre-test differences in TMVPA. Results showed that participants exposed to the intervention had significant increases in PA as measured by TMVPA (p = .027), TWS (p = .032), as well as exercise self-efficacy (p = .000) from pre-test to 6 weeks. Insignificant findings were reported for all three variables when measured from baseline to 12 weeks. In conclusion, the findings of the pilot study suggest that the intervention was effective in producing significant increases in PA in a sample of PLWHA of low SES over six weeks. Careful consideration of behavioural constructs, such as self-efficacy, can help WLWHA of low SES to adopt regular PA as a complementary therapy for managing their health.

The assessment of diurnal preference, or the preferred timing of sleep and activity, is generally based on comprehensive questionnaires such as the Horne-Östberg (HÖ). The aim of the present study was to assess the reliability of a subject's self-classification as extremely morning (Self-MM), more morning than evening (Self-M), more evening than morning (Self-E) or extremely evening (Self-EE) type, based on the last question of the HÖ (Self-ME). A convenience sample of 461 subjects [23.8 ± 4.7 years; 322 females] completed a full sleep-wake assessment, including diurnal preference (HÖ), night sleep quality (Pittsburgh Sleep Quality Index, PSQI), daytime sleepiness (Karolinska Sleepiness Scale, KSS), and habitual sleep-wake timing (12 d sleep diaries; n = 296). Significant differences in HÖ total score were observed between Self-ME classes, with each class being significantly different from neighboring classes (p < 0.0001). Significant differences in sleep-wake timing (bed time, try to sleep and sleep onset, wake up, and get up time) were observed between Self-ME classes. Such differences were maintained when sleep-wake habits were analysed separately on work and free days, and also in a smaller group of 67 subjects who completed the Self-ME as a stand-alone rather than as part of the original questionnaire. Significant differences were observed in the time-course of subjective sleepiness by Self-ME class in both the large and the small group, with Self-MM and Self-M subjects being significantly more alert in the morning and sleepier in the evening hours compared with their Self-E and Self-EE counterparts. Finally, significant differences were observed in night sleep quality between Self-ME classes, with Self-EE/Self-E subjects sleeping worse than their Self-MM/Self-M counterparts, and averaging just over the abnormality PSQI threshold of 5. In conclusion, young, healthy adults can define their diurnal preference based on a single question (Self-ME) in a way that reflects their sleep-wake timing, their sleepiness levels over the daytime hours, and their night sleep quality. Validation of the Self-ME across the decades and in diseased populations seems worthy.

To assess whether short-term feedback helps readers to increase their performance using computer-aided detection (CAD) for nodule detection in chest radiography. The 140 CXRs (56 with a solitary CT-proven nodules and 84 negative controls) were divided into four subsets of 35; each were read in a different order by six readers. Lesion presence, location and diagnostic confidence were scored without and with CAD (IQQA-Chest, EDDA Technology) as second reader. Readers received individual feedback after each subset. Sensitivity, specificity and area under the receiver-operating characteristics curve (AUC) were calculated for readings with and without CAD with respect to change over time and impact of CAD. CAD stand-alone sensitivity was 59 % with 1.9 false-positives per image. Mean AUC slightly increased over time with and without CAD (0.78 vs. 0.84 with and 0.76 vs. 0.82 without CAD) but differences did not reach significance. The sensitivity increased (65 % vs. 70 % and 66 % vs. 70 %) and specificity decreased over time (79 % vs. 74 % and 80 % vs. 77 %) but no significant impact of CAD was found. Short-term feedback does not increase the ability of readers to differentiate true- from false-positive candidate lesions and to use CAD more effectively. • Computer-aided detection (CAD) is increasingly used as an adjunct for many radiological techniques. • Short-term feedback does not improve reader performance with CAD in chest radiography. • Differentiation between true- and false-positive CAD for low conspicious possible lesions proves difficult. • CAD can potentially increase reader performance for nodule detection in chest radiography.

Religion and HIV/AIDS stigma: Implications for health professionals in Puerto Rico

HIV/AIDS stigma continues to be a barrier for prevention efforts. Its detrimental effects have been documented among people living with HIV/AIDS and encompass loss of social support and depression. When it is manifested by health professionals, it can lead to suboptimal services. Although strides have been made to document the effects of HIV/AIDS stigma, much needs to be done in order to understand the structural factors that can foster it. Such is the case of religion’s role on HIV/AIDS stigma in Puerto Rico. The Caribbean Island has a Judeo-Christian based culture due to years of Spanish colonisation. This religious influence continued under Protestantism as part of the Island’s integration as a non-incorporated territory of the USA. The main objective of this study was to explore the role of religion in HIV/AIDS stigma manifested by Puerto Rican health professionals in practice and in training. Through a mixed method approach, 501 health professionals completed qualitative interviews (n=80) and self-administered questionnaires (n=421). Results show that religion plays some role in conceptualisations of health and illness among participants in the study. Furthermore, the importance placed on religion and participation in such activities was related to higher levels of HIV/AIDS stigma. PMID:20087809

Integrating and decentralizing services are essential to increase the accessibility and provide comprehensive care for methadone patients. Moreover, they assure the sustainability of a HIV/AIDS prevention program by reducing the implementation cost. This study aimed to measure the preference of patients enrolling in a MMT program for integrated and decentralized MMT clinics and then further examine related factors. A cross-sectional study was conducted among 510 patients receiving methadone at 3 clinics in Hanoi. Structured questionnaires were used to collect data about the preference for integrated and decentralized MMT services. Covariates including socio-economic status; health-related quality of life (using EQ-5D-5 L instrument) and HIV status; history of drug use along with MMT treatment; and exposure to the discrimination within family and community were also investigated. Multivariate logistic regression with polynomial fractions was used to identify the determinants of preference for integrative and decentralized models. Of 510 patients enrolled, 66.7 and 60.8 % preferred integrated and decentralized models, respectively. The main reason for preferring the integrative model was the convenience of use of various services (53.2 %), while more privacy (43.5 %) was the primary reason to select stand-alone model. People preferred the decentralized model primarily because of travel cost reduction (95.0 %), while the main reason for not selecting the model was increased privacy (7.7 %). After adjusting for covariates, factors influencing the preference for integrative model were poor socioeconomic status, anxiety/depression, history of drug rehabilitation, and ever disclosed health status; while exposure to community discrimination inversely associated with this preference. In addition, people who were self-employed, had a longer duration of MMT, and use current MMT with comprehensive HIV services were less likely to select decentralized model. In conclusion, the study confirmed the high preference of MMT patients for the integrative and decentralized MMT service delivery models. The convenience of healthcare services utilization and reduction of geographical barriers were the main reasons to use those models within drug use populations in Vietnam. Countering community stigma and encouraging communication between patients and their societies needed to be considered when implementing those models.

I am pleased to have had the opportunity to revise the first version of this set of course notes for the stream temperature models. In some ways, there have been many changes and in some ways the notes have stayed much the same. Generally, I was satisfied that the notes were both comprehensive and fairly easy to read. The exercises using SSTEMP have been upgraded to reflect advances in the software. Some additional material was added to better cover contemporary thremistors, and some, but not all, weak transitions and incomplete sentences have been corrected. A comprehensive index was added in an attempt to make these notes as useful as possible, and a few telling quotes have been added for spice. The goal has been to make this set of notes as stand-alone as possible and keep the file size down to something that is easily downloadable over the Internet today (March 2000).

There is a growing recognition of the need to provide HIV/AIDS prevention and care to migrant workers. Social involvement, a type of social capital, is considered a 'critical enabler' of effective HIV/AIDS prevention. Designated participation in formal community groups by the government (e.g., political parties) and informal, voluntary local networks by NGOs (e.g., alumni association, cultural & sports club) play different roles in HIV prevention. The objective of this study is to assess the impact of different types of social organizations on HIV/AIDS prevention knowledge among migrant workers. A cross-sectional study of 758 migrants was conducted in Hefei, Anhui Province, China. Data were collected through a self-reported questionnaire. Logistic regression was used to assess associations between different social organizations and HIV/AIDS prevention. Migrants who participated in social organizations had a higher awareness of HIV/AIDS knowledge than migrants who do not participate in social organizations. Higher levels of HIV/AIDS knowledge is associated with positive HIV/AIDS behaviors for people who attended political parties (odds ratio [OR] = 3.49, 95% CI: 1.22-9.99). This effect is not significant for alumni association. For both political parties and alumni association members (OR = 0.19, 95% CI: 0.06-0.66, OR = 0.20, 95% CI: 0.08-0.61, respectively), people who exhibited higher levels of HIV/AIDS knowledge had more negative attitudes than those with less knowledge. Social organizations play an important role in improving HIV/AIDS knowledge and behavior in migrants, providing a great opportunity for HIV/AIDS prevention.

Introduction The current study aims to explore the knowledge, attitude, and perception of hospital pharmacists towards HIV/AIDS and patients living with HIV/AIDS (PLWHA) in the state of Kedah, Malaysia. Material and methods This was a cross-sectional study conducted among the hospital pharmacists in three government hospitals in Kedah, using a self-administered 43-item questionnaire. Data analysis was done using non-parametric and multinomial regression. Results A total of 75 respondents participated in this study, resulting in a response rate of 60.8%. The majority were found to be well aware of the causes of HIV/AIDS. However, about 34 (45.3%) believed erroneously that HIV/AIDS cannot be transmitted through tattooing or body piercing. Nearly 25 (33.3%) of the respondents believed that preventing the use of intravenous drugs may not be effective to prevent HIV/AIDS and endorsed social isolation as a measure to prevent HIV/AIDS. The majority (66.6%) had negative attitudes and about 20% held extremely negative attitudes. Findings from regression modelling revealed that hospital (–2 log likelihood = 215.182, χ2 = 18.060, Df = 8, p = 0.021) and gender (–2 log likelihood = 213.643, χ2 = 16.521, Df = 8, p = 0.035) were more likely to affect the attitudes of respondents. Conclusions Overall, more than one third of the respondents were found to have negative attitudes towards PLWHA. Gender, job experience, and hospitals with more HIV/AIDS patient visits were the main factors affecting attitudes. PMID:24482660

Operator function modeling: Cognitive task analysis, modeling and intelligent aiding in supervisory control systems

1990-01-01

The design, implementation, and empirical evaluation of task-analytic models and intelligent aids for operators in the control of complex dynamic systems, specifically aerospace systems, are studied. Three related activities are included: (1) the models of operator decision making in complex and predominantly automated space systems were used and developed; (2) the Operator Function Model (OFM) was used to represent operator activities; and (3) Operator Function Model Expert System (OFMspert), a stand-alone knowledge-based system was developed, that interacts with a human operator in a manner similar to a human assistant in the control of aerospace systems. OFMspert is an architecture for an operator's assistant that uses the OFM as its system and operator knowledge base and a blackboard paradigm of problem solving to dynamically generate expectations about upcoming operator activities and interpreting actual operator actions. An experiment validated the OFMspert's intent inferencing capability and showed that it inferred the intentions of operators in ways comparable to both a human expert and operators themselves. OFMspert was also augmented with control capabilities. An interface allowed the operator to interact with OFMspert, delegating as much or as little control responsibility as the operator chose. With its design based on the OFM, OFMspert's control capabilities were available at multiple levels of abstraction and allowed the operator a great deal of discretion over the amount and level of delegated control. An experiment showed that overall system performance was comparable for teams consisting of two human operators versus a human operator and OFMspert team.

This Phase I trial reports the results of a clinician-free Internet speech restructuring treatment for adults who stutter. The program consists of nine phases with concepts loosely based on the Camperdown Program. Twenty adults who stutter were recruited. They were given unlimited access to the program for 6 months. Primary outcome measures were the percentage of syllables stuttered and self-reported severity ratings. Five participants accessed all phases of the program, while another five accessed more than half the phases. The remaining 10 accessed between one and four phases. Four of five participants who accessed all phases reduced their stuttering frequency by more than 50% and an additional two participants who accessed more than half the phases also achieved similar reductions. These results were confirmed by self-reports of stuttering severity. Stuttering reductions were largely commensurate with the amount of the program accessed. As with other clinician-free programs in related health areas, maintaining adherence to the program's procedures was a significant issue. Nonetheless, this novel approach to treating stuttering has the potential to be a viable alternative for some clients and may help to address the significant access and relapse issues that affect treatment provision for adults who stutter.

Application of a tourniquet in a tactical environment is implemented in two ways: the so-called self-aid, which is the application of a tourniquet by the injured, and the so-called buddy aid, which is the application of a tourniquet by the person provide aid. This study aimed to test the quality of tourniquet use in a simulated situation, close quarter battle. The study involved 24 injured operators and 72 operators in the whole simulation, implying 12 sections of six individuals. To validate the application of tourniquets, the recommendations of the Committee of Tactical Combat Care of the Injured were used, and ultrasound with Doppler function was employed to assess the hemodynamic effect of applying tourniquets. Native flow was observed in 15 operators; in three people, a trace flow was noticed, whereas in six people, a full flow was observed. No significant difference was found between the qualities of tourniquet application by the operators themselves compared with those of tourniquet application by another person. The median distance of tourniquet application from the armpit was 9.5 cm for self-aid and buddy aid. In 16 participants the outer arrangement of tourniquets was observed, and in only eight participants tourniquets were correctly located on the internal part of the arm. In 18 participants, tourniquets were not correctly prepared for use in the tactical environment, whereas in only six participants, they were correctly prepared. Most operators with a negative ultrasound flow revealed negative distal observed pulse (DOP). Positive DOP occurred in the majority of operators with full ultrasound flow. The application of tourniquets poses a challenge even in case of specialized units; therefore, there is a need to provide regular training for implementing that procedure.

Comprehensive correct HIV/AIDS knowledge (CCAK) is defined as correctly identify the two major ways of preventing the sexual transmission of HIV, and reject the most common misconceptions about HIV transmission. There are limited studies on this topic in Sudan. In this study we investigated the Comprehensive correct HIV/AIDS knowledge among Universities students. A cross-sectional analytic study was conducted among 556 students from two universities in 2014. Data were collected by using the self-administered pre-tested structured questionnaire. Chi-square was used for testing the significance and P. Value of ≥ 0.05 is considered as statistically significant. The majority (97.1%) of study subjects have heard about a disease called HIV/AIDS, while only 28.6% of them knew anyone who is infected with AIDS in the local community. Minority (13.8%) of students had CCAK however, males showed a better level of CCAK than females (OR = 2.77) with high significant statistical differences (P. Value = 0.001). Poor rate of CCAK among university students is noticed, especially among females. Almost half of students did not know preventive measures of HIV, nearly two thirds had misconception, about one third did not know the mode of transmission of HIV.

This study was designed to examine the efficacy of video instruction relative to that of verbal and self-guided instruction. Before training, 30 golfers were assigned at random to one of three groups: video, verbal or self-guided instruction. Video instruction was defined as a practice session in which the teacher was aided by the use of video. Verbal instruction was defined as practising with the teacher providing verbal feedback. Self-guided practice was defined as practising without the aid of a teacher. The participants had a pre-test, four 90 min practice sessions, an immediate post-test and a 2 week delayed post-test. During the pre-test and post-tests, all participants were required to strike 15 golf balls, with a 7-iron, from an artificial turf mat for distance and accuracy. The results showed that all groups were equal on the pre-test. On the first post-test, the two instruction groups performed worse than the self-guided group. However, on the second post-test, the two instruction groups performed better than the self-guided group, with the video group performing best. We interpret these results to mean that video analysis is an effective means of practice, but that the positive effects may take some time to develop.

The objectives of this study were to determine efficacy of hearing aids in older adults using audiology best practices, to evaluate the efficacy of an alternative over-the-counter (OTC) intervention, and to examine the influence of purchase price on outcomes for both service-delivery models. The design of this study was a single-site, prospective, double-blind placebo-controlled randomized trial with three parallel branches: (a) audiology best practices (AB), (b) consumer decides OTC model (CD), and (c) placebo devices (P). Outcome measures were obtained after a typical 6-week trial period with follow-up 4-week AB-based trial for those initially assigned to CD and P groups. Older adults from the general community were recruited via newspaper and community flyers to participate at a university research clinic. Participants were adults, ages 55-79 years, with mild-to-moderate hearing loss. There were 188 eligible participants: 163 enrolled as a volunteer sample, and 154 completed the intervention. All participants received the same high-end digital mini-behind-the-ear hearing aids fitted bilaterally. AB and P groups received best-practice services from audiologists; differing mainly in use of appropriate (AB) or placebo (P) hearing aid settings. CD participants self-selected their own pre-programmed hearing aids via an OTC model. Primary outcome measure was a 66-item self-report, Profile of Hearing Aid Benefit (Cox & Gilmore, 1990). Secondary outcome measure was the Connected Speech Test (Cox, Alexander, & Gilmore, 1987) benefit. Additional measures of hearing-aid benefit, satisfaction, and usage were also obtained. Per-protocol analyses were performed. AB service-delivery model was found to be efficacious for most of the outcome measures, with moderate or large effect sizes (Cohen's d). CD service-delivery model was efficacious, with similar effect sizes. However, CD group had a significantly (p < .05) lower satisfaction and percentage (CD: 55%; AB: 81%; P: 36%) likely to purchase hearing aids after the trial. Hearing aids are efficacious in older adults for both AB and CD service-delivery models. CD model of OTC service delivery yielded only slightly poorer outcomes than the AB model. Efficacious OTC models may increase accessibility and affordability of hearing aids for millions of older adults. Purchase price had no effect on outcomes, but a high percentage of those who rejected hearing aids paid the typical price (85%).

In South Africa, the financing and sustainability of HIV services is a priority. Community-based HIV testing services (CB-HTS) play a vital role in diagnosis and linkage to HIV care for those least likely to utilise government health services. With insufficient estimates of the costs associated with CB-HTS provided by NGOs in South Africa, this cost analysis explored the cost to implement and provide services at two NGO-led CB-HTS modalities and calculated the costs associated with realizing key HIV outputs for each CB-HTS modality. The study took place in a peri-urban area where CB-HTS were provided from a stand-alone centre and mobile service. Using a service provider (NGO) perspective, all inputs were allocated by HTS modality with shared costs apportioned according to client volume or personnel time. We calculated the total cost of each HTS modality and the cost categories (personnel, capital and recurring goods/services) across each HTS modality. Costs were divided into seven pre-determined project components, used to examine cost drivers. HIV outputs were analysed for each HTS modality and the mean cost for each HIV output was calculated per HTS modality. The annual cost of the stand-alone and mobile modalities was $96,616 and $77,764 respectively, with personnel costs accounting for 54% of the total costs at the stand-alone. For project components, overheads and service provision made up the majority of the costs. The mean cost per person tested at stand-alone ($51) was higher than at the mobile ($25). Linkage to care cost at the stand-alone ($1039) was lower than the mobile ($2102). This study provides insight into the cost of an NGO led CB-HTS project providing HIV testing and linkage to care through two CB-HIV testing modalities. The study highlights; (1) the importance of including all applicable costs (including overheads) to ensure an accurate cost estimate that is representative of the full service implementation cost, (2) the direct link between test uptake and mean cost per person tested, and (3) the need for effective linkage to care strategies to increase linkage and thereby reduce the mean cost per person linked to HIV care.

Psychological pathway to suicidal ideation among people living with HIV/AIDS in China: A structural equation model.

People living with HIV/AIDS (PLWHA) have higher rates of suicide than does the general population. It is critical to interpret the intricate relationships among various psychological variables that increase the risk of suicidal ideation among PLWHA in China. An institutional based cross-sectional study was conducted from Jul to Aug 2016 in Nanjing, China, using a self-reporting questionnaire. A total of 465 PLWHA participated. Sociodemographic, psychological variables and suicide information about the participants were collected. Structural equation modeling (SEM)-path analysis was used to analyze the cross-sectional data. The final structural equation model had a highly satisfactory fit. Among PLWHA, perceived stigma had the greatest accumulated total effect on suicidal ideation, with both a direct effect and indirect effect through self-esteem and depression. Additionally, self-esteem had the second greatest total effect on suicidal ideation and was influenced by social support. Depression contributed directly to suicidal ideation and partly mediated the association of perceived stigma and self-esteem with suicidal ideation. These findings suggest that self-esteem and depression, particularly perceived stigma, play important roles in suicidal ideation among PLWHA. Enhancing personal self-esteem or social support might also reduce perceived stigma and may be an important target for intervention to decrease suicidal ideation among PLWHA.

To compare radiologic and clinical outcomes, including rates of dysphagia and dysphonia, using a no-profile stand-alone intervertebral spacer with integrated screw fixation versus an anterior cervical plate and spacer construct for single-level anterior cervical discectomy and fusion (ACDF) procedures. This multicenter, randomized, prospective study included 54 patients with degenerative disc disease requiring ACDF at a single level at C3-C7. Twenty-six patients underwent single-level ACDF with stand-alone spacers, and 28 with plate fixation and spacers. Analyses were based on comparison of perioperative outcomes, radiologic and clinical metrics, and incidence of dysphagia and/or dysphonia. Mean patient age was 48.8 ± 10.1years (53.7% female). No significant differences were observed between groups in operative time (101.8 ± 34.4 minutes, 114.4 ± 31.5 minutes), estimated blood loss (44.8 ± 76.5 mL, 82.5 ± 195.1 mL), or length of hospital stay (1.2 ± 0.6 days, 1.3 ± 0.6 days). Mean visual analog scale pain scores and Neck Disability Index scores improved significantly from preoperative to last follow-up (10.8 ± 2.6 months) in both groups (P < 0.05). Mean Voice Handicap Index and Eating Assessment Tool scores improved significantly from discharge to last follow-up in both groups (P < 0.05). From discharge to 6 months, the stand-alone spacers group consistently demonstrated greater improvement in Voice Handicap Index. Preoperative intervertebral disc and neuroforaminal heights increased significantly across treatment groups (P < 0.01), and no cases required surgical revision at index or adjacent levels. Anterior cervical discectomy and fusion with stand-alone spacers resulted in similar clinical and radiologic outcomes as compared with plate and spacers and may help minimize postoperative dysphonia.

The objective of this study was to summarize and critically assess the effects of interventions to prevent HIV/AIDS among adolescents in less developed countries. Reports of studies that evaluated interventions for preventing HIV/AIDS/STDs among persons aged 11-25 years were obtained from online computer databases, by searching conference proceedings and relevant journals, and by following up references cited in published reports. Studies were included if they investigated any educational, behavioral, psychosocial or other intervention that aimed to prevent or reduce HIV/AIDS/STD among persons aged 11-25 years in a less developed country. Only studies that included a control group, and which involved pre- and post-intervention assessments were included. Outcome measures included: (i) changes in safe sex practices (abstinence, condom use, limitation of sexual partners, avoidance of casual sex), (ii) knowledge about HIV/AIDS transmission and prevention methods, (iii) perception of HIV/AIDS/STD risks, (iv) self-efficacy with regard to condom negotiation and refusal of sex, (v) uptake of voluntary counseling and testing (VCT), and (vi) reduction in incidence of HIV/AIDS/STDs. Studies were assessed in terms of intervention format (e.g., education, role-play, video), duration, and setting (school or community). Reported improvements in outcome measures in intervention versus control groups were assessed. Sixteen studies met the inclusion criteria. Thirteen of these were conducted in Africa and three in Latin America. Twelve of the sixteen studies were school-based, and four were community-based. The interventions reviewed were not resoundingly successful in achieving their goals of increasing knowledge of HIV/AIDS, altering attitudes, improving negotiation and communication skills, or in influencing positive behavior evidenced through consistent condom use, abstinence, or reducing the number of partners. Considering the importance of HIV/AIDS prevention among adolescents, design of evaluation studies of programs in less developed countries need to be improved. The use of randomized controlled trials or other rigorous approaches for evaluating population-based behavioral interventions (e.g., Solomon Four design) is recommended.

Objective Cross-national studies provide inconclusive results as to the effectiveness of foreign health aid. We highlight a novel application of using subnational data to evaluate aid impacts, using Malawi as a case study. Design We employ two rounds of nationally representative household surveys (2004/2005 and 2010/2011) and geo-referenced foreign aid data. We examine the determinants of Malawi's traditional authorities receiving aid according to health, environmental risk, socioeconomic and political factors. We use two approaches to estimate the impact of aid on reducing malaria prevalence and increasing healthcare quality: difference-in-difference models, which include traditional authority and month-of-interview fixed effects and control for individual and household level time-varying factors, and entropy balancing, where models balance on health-related and socioeconomic baseline characteristics. General health aid and four specific health aid sectors are examined. Results Traditional authorities with greater proportions of individuals living in urban areas, more health facilities and greater proportions of those in major ethnic groups were more likely to receive aid. Difference-in-difference models show health infrastructure and parasitic disease control aid reduced malaria prevalence by 1.20 (95% CI −0.36 to 2.76) and 2.20 (95% CI 0.43 to 3.96) percentage points, respectively, and increased the likelihood of individuals reporting healthcare as more than adequate by 12.1 (95% CI 1.51 to 22.68) and 14.0 (95% CI 0.11 to 28.11) percentage points. Entropy balancing shows similar results. Conclusions Aid was targeted to areas with greater existing health infrastructure rather than areas most in need, but still effectively reduced malaria prevalence and enhanced self-reported healthcare quality.

The impact of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) on the participation of women in paid/unpaid work is a little understood phenomenon. A research study exploring the lived experiences of Canadian women's engagement in paid/unpaid work and the barriers and facilitators mediating this phenomenon. Study design employed a phenomenological approach using data subanalysis of transcripts, double coded for agreement and to ensure saturation of themes. Analysis of the data revealed an overarching theme of engagement mediated by interacting forces with eight subthemes: active management, agency constrained by structure, the nature of supports, HIV/AIDS sequelae, work as a galvanizing force, the presence of children, the element of fear, and negotiation of self. Insights gained indicate a need for further education, resources, supports, and policy changes at the systems level. Occupational therapy is positioned to broaden the role of rehabilitation in the context of HIV/AIDS, episodic disability, and work participation.

Many adolescents with developmental disabilities do not learn the safety skills needed to maintain physical well-being in domestic and community environments. Literacy-based behavioral interventions (LBBIs) that combine print, pictures, and behavioral rehearsal are effective for promoting acquisition and maintenance of self-care skills, but have not been investigated as safety skill intervention. Also, LBBIs have primarily been implemented by teachers and other professionals. In this study, a peer partner was taught to deliver an LBBI story to students so they would learn to perform a basic first aid routine: cleaning and dressing a wound. Results showed that students' accuracy with the first aid routine increased after a peer delivered the LBBI instructional package, and maintained after the peer stopped delivering it. This study demonstrates the effectiveness of the LBBI instructional package for teaching first aid safety skills, and extends previous research showing the efficacy of peers in delivering this intervention.

Previous research has shown that hearing aid wearers can successfully self-train their instruments' gain-frequency response and compression parameters in everyday situations. Combining hearing aids with a smartphone introduces additional computing power, memory, and a graphical user interface that may enable greater setting personalization. To explore the benefits of self-training with a smartphone-based hearing system, a parameter space was chosen with four possible combinations of microphone mode (omnidirectional and directional) and noise reduction state (active and off). The baseline for comparison was the "untrained system," that is, the manufacturer's algorithm for automatically selecting microphone mode and noise reduction state based on acoustic environment. The "trained system" first learned each individual's preferences, self-entered via a smartphone in real-world situations, to build a trained model. The system then predicted the optimal setting (among available choices) using an inference engine, which considered the trained model and current context (e.g., sound environment, location, and time). To develop a smartphone-based prototype hearing system that can be trained to learn preferred user settings. Determine whether user study participants showed a preference for trained over untrained system settings. An experimental within-participants study. Participants used a prototype hearing system-comprising two hearing aids, Android smartphone, and body-worn gateway device-for ∼6 weeks. Sixteen adults with mild-to-moderate sensorineural hearing loss (HL) (ten males, six females; mean age = 55.5 yr). Fifteen had ≥6 mo of experience wearing hearing aids, and 14 had previous experience using smartphones. Participants were fitted and instructed to perform daily comparisons of settings ("listening evaluations") through a smartphone-based software application called Hearing Aid Learning and Inference Controller (HALIC). In the four-week-long training phase, HALIC recorded individual listening preferences along with sensor data from the smartphone-including environmental sound classification, sound level, and location-to build trained models. In the subsequent two-week-long validation phase, participants performed blinded listening evaluations comparing settings predicted by the trained system ("trained settings") to those suggested by the hearing aids' untrained system ("untrained settings"). We analyzed data collected on the smartphone and hearing aids during the study. We also obtained audiometric and demographic information. Overall, the 15 participants with valid data significantly preferred trained settings to untrained settings (paired-samples t test). Seven participants had a significant preference for trained settings, while one had a significant preference for untrained settings (binomial test). The remaining seven participants had nonsignificant preferences. Pooling data across participants, the proportion of times that each setting was chosen in a given environmental sound class was on average very similar. However, breaking down the data by participant revealed strong and idiosyncratic individual preferences. Fourteen participants reported positive feelings of clarity, competence, and mastery when training via HALIC. The obtained data, as well as subjective participant feedback, indicate that smartphones could become viable tools to train hearing aids. Individuals who are tech savvy and have milder HL seem well suited to take advantages of the benefits offered by training with a smartphone. American Academy of Audiology

Bystander first aid can improve survival following out-of-hospital cardiac arrest or trauma. Thus, providing first aid education to laypersons may lead to better outcomes. In this study, we aimed to establish the prevalence and distribution of first aid training in the populace, how often first aid skills are needed, and self-reported helping behaviour. We conducted a telephone survey of 1000 respondents who were representative of the Norwegian population. Respondents were asked where and when they had first aid training, if they had ever encountered situations where first aid was necessary, and stratified by occupation. First aid included cardio-pulmonary resuscitation (CPR) and basic life support (BLS). To test theoretical first aid knowledge, respondents were subjected to two hypothetical first aid scenarios. Among the respondents, 90% had received first aid training, and 54% had undergone first aid training within the last 5 years. The workplace was the most common source of first aid training. Of the 43% who had been in a situation requiring first aid, 89% had provided first aid in that situation. There were considerable variations among different occupations in first aid training, and exposure to situations requiring first aid. Theoretical first aid knowledge was not as good as expected in light of the high share who had first aid training. In the presented scenarios 42% of respondent would initiate CPR in an unconscious patient not breathing normally, and 46% would provide an open airway to an unconscious road traffic victim. First aid training was correlated with better theoretical knowledge, but time since first aid training was not. A high proportion of the Norwegian population had first aid training, and interviewees reported high willingness to provide first aid. Theoretical first aid knowledge was worse than expected. While first aid is part of national school curriculum, few have listed school as the source for their first aid training.

Objective. To evaluate the impact of a standalone, patient-centered communication (PCC) course series on student achievement of and perceived preparedness for PCC skills and to assess student attitudes regarding learning methods used. Design. During curriculum renewal, a standalone PCC course series that integrated horizontally and vertically within the curriculum was developed. Student achievement of outcomes was evaluated by aggregate performance on simulated evaluations. Students who completed the PCC series were surveyed to assess preparedness and attitudes. Students in the prior curriculum were also surveyed. Assessment. The majority of students who completed the PCC series met or exceeded expectations for the simulated evaluations. Preparedness responses were more positive from students who completed the PCC series than from those who completed the prior curriculum. Student attitudes about the learning methods use in the courses also were more positive. Conclusion. The standalone PCC course series effectively achieved PCC outcomes and improved student preparedness for communication-based activities.

Since 2006, Medicare beneficiaries have been able to obtain prescription drug coverage through standalone prescription drug plans or their Medicare Advantage (MA) health plan, options exercised in 2015 by 72 percent of beneficiaries. Using data from community-dwelling Medicare beneficiaries older than age sixty-four in 700 plans surveyed from 2007 to 2014, we compared beneficiaries' assessments of Medicare prescription drug coverage when provided by standalone plans or integrated into an MA plan. Beneficiaries in standalone plans consistently reported less positive experiences with prescription drug plans (ease of getting medications, getting coverage information, and getting cost information) than their MA counterparts. Because MA plans are responsible for overall health care costs, they might have more integrated systems and greater incentives than standalone prescription drug plans to provide enrollees medications and information effectively, including, since 2010, quality bonus payments to these MA plans under provisions of the Affordable Care Act.

1981-11-01

The final result of an international assessment of the market for stand-alone photovoltaic systems in cottage industry applications is reported. Nonindustrialized countries without centrally planned economies were considered. Cottage industries were defined as small rural manufacturers, employing less than 50 people, producing consumer and simple products. The data to support this analysis were obtained from secondary and expert sources in the U.S. and in-country field investigations of the Philippines and Mexico. The near-term market for photovoltaics for rural cottage industry applications appears to be limited to demonstration projects and pilot programs, based on an in-depth study of the nature of cottage industry, its role in the rural economy, the electric energy requirements of cottage industry, and a financial analysis of stand-alone photovoltaic systems as compared to their most viable competitor, diesel driven generators. Photovoltaics are shown to be a better long-term option only for very low power requirements. Some of these uses would include clay mixers, grinders, centrifuges, lathes, power saws and lighting of a workshop.

Transforming breast cancer control campaigns in low and middle-income settings: Tanzanian experience with 'Check It, Beat It'.

Kassam, Dilshad; Berry, Nicole S; Dharsee, Jaffer

Breast cancer incidence and mortality rates are similar in low resource settings like Tanzania. Structural and sociocultural barriers make late presentation typical in such settings where treatment options for advanced stage disease are limited. In the absence of national programmes, stand-alone screening campaigns tend to employ clinical models of delivery focused on individual behaviour and through a disease specific lens. This paper describes a case study of a 2010 stand-alone campaign in Tanzania to argue that exclusively clinical approaches can undermine screening efforts by premising that women will act outside their social and cultural domain when responding to screening services. A focus on sociocultural barriers dictated the approach and execution of the intervention. Our experience concurs with that in similar settings elsewhere, underscoring the importance of barriers situated within the sociocultural milieu of societies when considering prevention interventions. Culturally competent delivery could contribute to long-term reductions in late stage presentation and increases in treatment acceptance. We propose a paradigm shift in the approach to stand-alone prevention programmes.

An estimation of a stand-alone solar PV and wind hybrid system for distributed power generation has been made based on the resources available at Sagar island, a remote area distant to grid operation. Optimization and sensitivity analysis has been made to evaluate the feasibility and size of the power generation unit. A comparison of the different modes of hybrid system has been studied. It has been estimated that Solar PV-Wind-DG hybrid system provides lesser per unit electricity cost. Capital investment is observed to be lesser when the system run with Wind-DG compared to Solar PV-DG.

Extremely low-frequency (ELF) magnetic field (MF) measurements around and above three stand-alone 22/0.4-kV transformer stations have been performed. The low-voltage (LV) cables between the transformer and the LV switchgear were found to be the major source of strong ELF MFs of limited spatial extent. The strong fields measured above the transformer stations support the assessment method, to be used in future epidemiological studies, of classifying apartments located right above the transformer stations as highly exposed to MFs. The results of the MF measurements above the ground around the transformer stations provide a basis for the assessment of the option of implementing precautionary procedures.

2014-06-01

413 (119 men, 294 women) undergraduate university students in Qatar completed an Arabic version of the Learning and Study Strategies Inventory (LASSI) measuring Anxiety, Attitude, Concentration, Information Processing, Motivation, Self-testing, Selecting Main Ideas, Study Aids, Time Management, and Test Strategies. The students' learning and study strategies scores were similar to those reported in the literature. Factor analysis indicated the same general factors as in the original study. Internal consistency estimates ranged from .62 to .88. Nine of the 10 scales (i.e., all with the exception of the Study Aids) significantly correlated with students' GPAs. Scores obtained from these scales provide valid assessments of Qatar University students' use of learning and study strategies related to skill, will, and self-regulation components of strategic learning and also academic achievement. There also were statistically significant differences between higher and lower achieving students in their learning and study strategies. This study also explored the use of the LASSI as a predictive measure of academic achievement. Anxiety and test strategies were significant predictors of academic achievement as measured by students' GPA.

Chronic pain can contribute to disability, depression, anxiety, sleep disturbances, poor quality of life and increased health care costs, with close to 20 % of the adult population in Europe reporting chronic pain. To empower the person to self-manage, it is advocated that education and training about the nature of pain and its effects and how to live with pain is provided. The objective of this review is to determine the level of evidence for education to facilitate knowledge about chronic pain, delivered as a stand-alone intervention for adults, to reduce pain and disability. We identified randomised controlled trials of educational intervention for chronic pain by searching CENTRAL, MEDLINE, EMBASE and ongoing trials registries (inception to December 2013). Main inclusion criteria were (1) pain >3 months; (2) study design that allowed isolation of effects of education and (3) measures of pain or disability. Two reviewers independently screened and appraised each study. Nine studies were analysed. Pooled data from five studies, where the comparator group was usual care, showed no improvement in pain or disability. In the other four studies, comparing different types of education, there was no evidence for an improvement in pain; although, there was evidence (from one study) of a decrease in disability with a particular form of education-pain neurophysiology education (PNE). Post-hoc analysis of psychosocial outcomes reported in the studies showed evidence of a reduction in catastrophising and an increase of knowledge about pain following PNE. The evidence base is limited by the small numbers of studies, their relatively small sample sizes, and the diversity in types of education studied. From that limited evidence, the only support for this type of education is for PNE, though it is insufficiently strong to recommend conclusively that PNE should be delivered as a stand-alone intervention. It therefore remains sensible to recommend that education be delivered in conjunction with other pain management approaches as we cannot confidently conclude that education alone is effective in reducing pain intensity or related disability in chronic pain in adults.

The use of patient-reported outcome (PRO) measures to assess self-reported difficulty in visual activities is common in patients with impaired vision. This study determines the visual and psychosocial factors influencing patients' responses to self-report measures, to aid in understanding what is being measured. One hundred visually impaired participants completed the Activity Inventory (AI), which assesses self-reported, vision-related activity limitation (VRAL) in the task domains of reading, mobility, visual information, and visual motor tasks. Participants also completed clinical tests of visual function (distance visual acuity and near reading performance both with and without low vision aids [LVAs], contrast sensitivity, visual fields, and depth discrimination), and questionnaires assessing depressive symptoms, social support, adjustment to visual loss, and personality. Multiple regression analyses identified that an acuity measure (distance or near), and, to a lesser extent, near reading performance without LVAs, visual fields, and contrast sensitivity best explained self-reported VRAL (28%-50% variance explained). Significant psychosocial correlates were depression and adjustment, explaining an additional 6% to 19% unique variance. Dependent on task domain, the parameters assessed explained 59% to 71% of the variance in self-reported VRAL. Visual function, most notably acuity without LVAs, is the best predictor of self-reported VRAL assessed by the AI. Depression and adjustment to visual loss also significantly influence self-reported VRAL, largely independent of the severity of visual loss and most notably in the less vision-specific tasks. The results suggest that rehabilitation strategies addressing depression and adjustment could improve perceived visual disability.

This document describes the results and analysis of the formal evaluation plan for the Honeywell software tool developed under the NASA AWIN (Aviation Weather Information) 'Weather Avoidance using Route Optimization as a Decision Aid' project. The software tool aims to provide airline dispatchers with a decision aid for selecting optimal routes that avoid weather and other hazards. This evaluation compares and contrasts route selection performance with the AWIN tool to that of subjects using a more traditional dispatcher environment. The evaluation assesses gains in safety, in fuel efficiency of planned routes, and in time efficiency in the pre-flight dispatch process through the use of the AWIN decision aid. In addition, we are interested in how this AWIN tool affects constructs that can be related to performance. The construct of Situation Awareness (SA), workload, trust in an information system, and operator acceptance are assessed using established scales, where these exist, as well as through the evaluation of questionnaire responses and subject comments. The intention of the experiment is to set up a simulated operations area for the dispatchers to work in. They will be given scenarios in which they are presented with stored company routes for a particular city-pair and aircraft type. A diverse set of external weather information sources is represented by a stand-alone display (MOCK), containing the actual historical weather data typically used by dispatchers. There is also the possibility of presenting selected weather data on the route visualization tool. The company routes have not been modified to avoid the weather except in the case of one additional route generated by the Honeywell prototype flight planning system. The dispatcher will be required to choose the most appropriate and efficient flight plan route in the displayed weather conditions. The route may be modified manually or may be chosen from those automatically displayed.

Background Decisions about prenatal screening for Down syndrome are difficult for women, as they entail risk, potential loss, and regret. Shared decision making increases women’s knowledge of their choices and better aligns decisions with their values. Patient decision aids foster shared decision making but are rarely used in this context. Objective One of the most promising strategies for implementing shared decision making is distribution of decision aids by health professionals. We aimed to identify factors influencing their intention to use a DA during prenatal visit for decisions about Down syndrome screening. Methods We conducted a cross-sectional quantitative study. Using a Web panel, we conducted a theory-based survey of health professionals in Quebec province (Canada). Eligibility criteria were as follows: (1) family physicians, midwives, obstetrician-gynecologists, or trainees in these professions; (2) involved in prenatal care; and (3) working in Quebec province. Participants watched a video depicting a health professional using a decision aid during a prenatal consultation with a woman and her partner, and then answered a questionnaire based on an extended version of the theory of planned behavior, including some of the constructs of the theoretical domains framework. The questionnaire assessed 8 psychosocial constructs (attitude, anticipated regret, subjective norm, self-identity, moral norm, descriptive norm, self-efficacy, and perceived control), 7 related sets of behavioral beliefs (advantages, disadvantages, emotions, sources of encouragement or discouragement, incentives, facilitators, and barriers), and sociodemographic data. We performed descriptive, bivariate, and multiple linear regression analyses to identify factors influencing health professionals’ intention to use a decision aid. Results Among 330 health professionals who completed the survey, 310 met the inclusion criteria: family physicians, 55.2% (171/310); obstetrician-gynecologists, 33.8% (105/310); and midwives, 11.0% (34/310). Of these, 80.9% were female (251/310). Mean age was 39.6 (SD 11.5) years. Less than half were aware of any decision aids at all. In decreasing order of importance, factors influencing their intention to use a decision aid for Down syndrome prenatal screening were as follows: self-identity (beta=.325, P<.001), attitude (beta=.297, P<.001), moral norm (beta=.288, P<.001), descriptive norm (beta=.166, P<.001), and anticipated regret (beta=.099, P=.003). Underlying behavioral beliefs significantly related to intention were that the use of a decision aid would promote decision making (beta=.117, 95% CI 0.043-0.190), would reassure health professionals (beta=.100, 95% CI 0.024-0.175), and might require more time than planned for the consultation (beta=−.077, 95% CI −0.124 to −0.031). Conclusions We identified psychosocial factors that could influence health professionals’ intention to use a decision aid about Down syndrome screening. Strategies should remind them of the following: (1) using a decision aid for this purpose should be a common practice, (2) it would be expected of someone in their societal role, (3) the experience of using it will be satisfying and reassuring, and (4) it is likely to be compatible with their moral values.

2001-08-01

This study evaluated an intervention designed to improve behavioral and mental health outcomes among adolescents and their parents with AIDS. Parents with AIDS (n = 307) and their adolescent children (n = 412) were randomly assigned to an intensive intervention or a standard care control condition. Ninety-five percent of subjects were reassessed at least once annually over 2 years. Adolescents in the intensive intervention condition reported significantly lower levels of emotional distress, of multiple problem behaviors, of conduct problems, and of family-related stressors and higher levels of self-esteem than adolescents in the standard care condition. Parents with AIDS in the intervention condition also reported significantly lower levels of emotional distress and multiple problem behaviors. Coping style, levels of disclosure regarding serostatus, and formation of legal custody plans were similar across intervention conditions. Interventions can reduce the long-term impact of parents' HIV status on themselves and their children.

We examined the meaning of living with HIV/AIDS among women in Lebanon. Ten women living with HIV/AIDS (WLWHA) described their experiences via semistructured in-depth interviews. They navigated a process of HIV diagnosis acceptance that incorporated six overlapping elements: receiving the news, accessing care, starting treatment, navigating disclosure decisions, negotiating stigma, and maintaining stability. Through these elements, we provide a framework for understanding three major themes that were constructed during data analysis: Stand by my side: Decisions of disclosure; Being "sick" and feeling "normal": Interacting with self, others, and society; and Living day by day: focusing on the present. We contribute to the existing literature by providing a theoretical framework for understanding the process of diagnosis and sero-status acceptance among WLWHA. This was the first study of its kind to examine the meaning of living with HIV/AIDS among women in a Middle Eastern country.

Individual in-depth interviews were conducted with 47 children (ages 8-17 years) experiencing the loss of one or both parents due to HIV/AIDS in two rural counties of central China. Findings in this study reveal that the families of the children orphaned by AIDS had experienced financial burdens because of treatment costs for sick parents and loss of labor in the household. The majority of the participants reported some level of stigmatization because of their parents' HIV status. The participants described feelings of sadness, fear, anxiety, anger, loneliness, low self-esteem, social withdrawal, and sleep problems. Implications for intervention programs include the need for psychological support and special counseling services, more public education with accurate knowledge about HIV/AIDS to decrease stigma and discrimination, and financial programs to decrease economic and caregiving burdens for these children.

Each industrial 6-DOF arm is able to be used as a stand-alone industrial 6-DOF robot manipulator and as a part of dual arm manipulator at the same time. These structures help the robot maker which is willing to succeed in the emerging dual arm robot market in order to have high competition for the current industrial robot market at same time. Self-collision detection algorithm for multi-arm robot and kinematics algorithms for the developed dual arm robot manipulator which are implemented in our controller are introduced.

Sad mood promotes self-initiated mental contrasting of future and reality.

Kappes, Heather Barry; Oettingen, Gabriele; Mayer, Doris; Maglio, Sam

2011-10-01

Self-regulation by mentally contrasting a positive future with negative reality leads people to differentiate in their goal commitments: They commit to goals when expectations of success are high and let go when expectations of success are low. On the contrary, when indulging in the positive future or dwelling on negative reality, people fail to consider expectations of success and do not form selective goal commitments (Oettingen, Pak, & Schnetter, 2001). Whereas prior research has examined the effects of experimentally induced mental contrasting, we address sad mood as a contextual influence promoting self-initiated mental contrasting. Across various mood inductions, sad moods--which are associated with problem solving strategies--facilitated self-initiated mental contrasting more than neutral moods (Studies 1, 5) or happy moods (Studies 2, 3, 4, 6). Importantly, mood did not affect the relation between mental contrasting and selective formation of goal commitment (Studies 5, 6). The results suggest that sad moods aid in self-regulation by making people self-initiate goal commitments that are sensitive to their expectations of success.

This study carried out to survey the relationship between personality traits and Acquired Immunodeficiency Syndrome (AIDS) in patients with human immunodeficiency virus. This case-control study was conducted on 79 AIDS patients of Triangle Clinic in Arak (case group) and 80 healthy people of Valiasr Hospital in Arak (control group). Demographic information checklist and Cloninger' Temperament and Character inventory (TCI) were two instruments applied in the study. SPSS software V.19 and tests independent t-tests, Chi squared and Spearman correlation coefficient were used for data analysis with significant level of <0.05. The average of innovativeness variables (M:74.12), harm avoidance (M: 65.17), reward dependence (M:50.030), and self-directedness (M:35.02) in case group in comparison with control group was significantly higher, and there was a significant difference between two groups variables (P-0.000). The novelty seeking had the highest average in the AIDS patients with a history of addiction (M:74.00), and there was statistically significant difference between perseverance variable (P-0.021) and cooperativeness variable (P-0.041) in the two groups of AIDS patients. There was a significant relationship between novelty seeking and age at the onset of AIDS (P-0.038), harm avoidance and age at the onset of addiction (P-0.046), persistence and age at the onset of AIDS (P-0.035) and the time infected with HIV (P-0.033). It is found that two groups are different due to the personalities, so it is essential to consider the personality traits in order to prevent AIDS and also successfully treat patients suffering from AIDS.

Background Injuries are very common and can occur at any point of time in a day. Unintended injuries in kindergarten children are the most common and need immediate life saving care which is known as first aid. This study aimed to investigate knowledge, attitude, practice, and associated factors of first aid among kindergarten teachers of Lideta sub-city Addis Ababa, Ethiopia. Method A cross-sectional study was conducted among kindergarten teachers. Data was collected using pretested, structured and self-administered questionnaire S1 File. The collected data was entered in to Epi Data version 3.1 software and analyzed using SPSS version 20. Logistic regression analysis was used to identify association between kindergarten teachers’ knowledge and attitudes towards first aid and different variables. Odds ratios with 95% CI and p<0.05 were computed to determine the presence of the association. Result One hundred and ninety-four teachers participated in the study with a response rate of 95%. Only 40% of the teachers were knowledgeable and 75% of them had positive attitude for first aid. Eighty percent of teachers encountered with children in need of first aid. Kindergarten teachers older than 35 years [AOR = 4.2, 95%CI: (1.02, 16.9)], five years’ experience [AOR = 3.1, 95%CI: (1.2, 7.6)], having previous first aid training [AOR = 3.1, 95%CI: (1.2, 7.7)], source of first aid information and teachers serving in private kindergarten are associated with having knowledge of first aid. Long time experience, type of kindergarten, previous training, and exposure to children in need of first aid were positive association with attitude towards first aid. Conclusion Low first aid knowledge and high positive attitude among kindergarten teachers. Having long time experience, being older age, previous first aid training, and serving in private kindergarten were positively associated with first aid knowledge and positive attitude. Creating awareness and including first aid courses in the kindergarten teachers’ curriculum need to be considered. PMID:29534091

The incidence of infection with HIV/AIDS among the heterosexual population has been increasing in young adults. The goal of this research was to deepen knowledge of preventive sexual behavior in Portuguese adolescents, including knowledge and attitudes about HIV/AIDS, and assessing whether they changed from 2002 to 2006. Data were collected through a self-administered questionnaire from the Portuguese sample of the Health Behavior in School-aged Children (HBSC), a collaborative WHO study. The study provides national representative data of 7093 Portuguese adolescents, randomly chosen from those attending 8th and 10th grade of high school. Results showed there was an increase in the age of first sexual intercourse and a decrease in the number of teenagers who reported having had sexual intercourse, also in the level of information regarding HIV/AIDS transmission/prevention and in positive attitudes towards people with HIV/AIDS. In general, adolescents have good knowledge about how to protect themselves from becoming infected. However, comparing to 2002, there was a reduction of knowledge and consequent increase in the doubts regarding HIV/AIDS. Given the incipient state of sex education in 2006, the results cannot be attributed to sex education, but they will be relevant for comparison with the 2010 HBSC results.

Using theatrical presentations as a means of disseminating knowledge of HIV/AIDS risk factors to migrant farmworkers: an evaluation of the effectiveness of the Infórmate program.

PubMed

Hovey, Joseph D; Booker, Victoria; Seligman, Laura D

2007-04-01

Previous research has suggested that Mexican migrant farmworkers are at elevated risk for contracting HIV/AIDS and that they are in need of receiving HIV/AIDS-related education. The present study evaluated the impact of the Infórmate adolescent theater program on HIV/AIDS knowledge and attitudes among farmworker audience members of various ages. Audience members from 7 migrant farmworker camps completed a self-administered questionnaire before and after they observed the Infórmate performance. Paired-samples t-tests and McNemar tests indicated an increase in knowlege in "modes of HIV transmission," "body fluids that can transmit HIV," and items assessing HIV/AIDS "myths." In addition, a greater percentage of farmworkers at posttest reported that they believed that condoms should always be used during sex. The overall findings from this study suggest that theater can be an effective medium for increasing HIV/AIDS-related knowledge among migrant farmworkers. However, it is suggested that, because some farmworkers held false beliefs regarding modes of HIV transmission after viewing the theater program, theater used in combination with other prevention activities may provide for a more comprehensive educational experience.

Motivational engagement in first-time hearing aid users: A feasibility study.

To assess (1) the feasibility of incorporating the Ida Institute's Motivation Tools into a UK audiology service, (2) the potential benefits of motivational engagement in first-time hearing aid users, and (3) predictors of hearing aid and general health outcome measures. A feasibility study using a single-centre, prospective, quasi-randomized controlled design with two arms. The Ida Institute's Motivation Tools formed the basis for motivational engagement. First-time hearing aid users were recruited at the initial hearing assessment appointment. The intervention arm underwent motivational engagement (M+, n = 32), and a control arm (M-, n = 36) received standard care only. The M+ group showed greater self-efficacy, reduced anxiety, and greater engagement with the audiologist at assessment and fitting appointments. However, there were no significant between-group differences 10-weeks post-fitting. Hearing-related communication scores predicted anxiety, and social isolation scores predicted depression for the M+ group. Readiness to address hearing difficulties predicted hearing aid outcomes for the M- group. Hearing sensitivity was not a predictor of outcomes. There were some positive results from motivational engagement early in the patient journey. Future research should consider using qualitative methods to explore whether there are longer-term benefits of motivational engagement in hearing aid users.

Germline genomic testing is increasingly used in research to identify genetic causes of disease, including cancer. However, there is evidence that individuals who are notified of clinically actionable research findings have difficulty making informed decisions regarding uptake of genetic counseling for these findings. This study aimed to produce and pilot test a decision aid to assist participants in genomic research studies who are notified of clinically actionable research findings to make informed choices regarding uptake of genetic counseling. Development was guided by published literature, the International Patient Decision Aid Standards, and the expertise of a steering committee of clinicians, researchers, and consumers. Decision aid acceptability was assessed by self-report questionnaire. All 19 participants stated that the decision aid was easy to read, clearly presented, increased their understanding of the implications of taking up research findings, and would be helpful in decision-making. While low to moderate levels of distress/worry were reported after reading the booklet, a majority of participants also reported feeling reassured. All participants would recommend the booklet to others considering uptake of clinically actionable research findings. Results indicate the decision aid is acceptable to the target audience, with potential as a useful decision support tool for genomic research participants.

Existing research suggests that the rate of depressive illness and depressive symptoms are high in people living with HIV/AIDS, but investigations on the causes of depression provide conflicting results. Social, psychological and biological factors have all been suggested as possible causes of depression in people living with HIV/AIDS. The suggestion that depression may be the result of the neurotropic effects of the virus on the central nervous system leading to an 'organic' or secondary depression has major implications in the treatment of HIV/AIDS. The aim of the current study was to further investigate the nature and underlying aetiology of depression in people living with HIV/AIDS. One hundred and twenty-nine people living with HIV/AIDS recruited for the study from outpatients clinics and primary care settings completed a range of self-report symptom measures including the Beck Depression Inventory (BDI), SF-36, SPHERE and a personality measure, the NEO Personality Inventory (NEO-PI). They also completed a battery of neuropsychological tests (CANTAB) and a structured clinical interview (SCID-DSM-IV). Medical and sociodemographic data were also recorded. Approximately one-third scored > or = 14 on the BDI and 27% met criteria for a current 'mood disorder' on the SCID. Depressive symptoms were strongly related to personality style, having a past psychiatric history and current stressful psychosocial situation. There was no association between depression and HIV disease status. There was no evidence in this study cohort of a distinct subtype of 'organic' or secondary depression. These results suggest that at least for 'well' people living with HIV/AIDS, there is no distinct subtype of depression and early treatment approaches can be modelled on those used for other non-HIV groups. Further longitudinal studies will be required to dissect out the multiple factors underlying depression in HIV/AIDS.

Comparing the effect of a decision aid plus patient navigation with usual care on colorectal cancer screening completion in vulnerable populations: study protocol for a randomized controlled trial

PubMed Central

2014-01-01

Background Screening can reduce colorectal cancer (CRC) incidence and mortality. However, screening is underutilized in vulnerable patient populations, particularly among Latinos. Patient-directed decision aids can increase CRC screening knowledge, self-efficacy, and intent; however, their effect on actual screening test completion tends to be modest. This is probably because decision aids do not address some of the patient-specific barriers that prevent successful completion of CRC screening in these populations. These individual barriers might be addressed though patient navigation interventions. This study will test a combined decision aid and patient navigator intervention on screening completion in diverse populations of vulnerable primary care patients. Methods/Design We will conduct a multisite, randomized controlled trial with patient-level randomization. Planned enrollment is 300 patients aged 50 to 75 years at average CRC risk presenting for appointments at two primary clinics in North Carolina and New Mexico. Intervention participants will view a video decision aid immediately before the clinic visit. The 14 to 16 minute video presents information about fecal occult blood tests and colonoscopy and will be viewed on a portable computer tablet in English or Spanish. Clinic-based patient navigators are bilingual and bicultural and will provide both face-to-face and telephone-based navigation. Control participants will view an unrelated food safety video and receive usual care. The primary outcome is completion of a CRC screening test at six months. Planned subgroup analyses include examining intervention effectiveness in Latinos, who will be oversampled. Secondarily, the trial will evaluate the intervention effects on knowledge of CRC screening, self-efficacy, intent, and patient-provider communication. The study will also examine whether patient ethnicity, acculturation, language preference, or health insurance status moderate the intervention effect on CRC screening. Discussion This pragmatic randomized controlled trial will test a combined decision aid and patient navigator intervention targeting CRC screening completion. Findings from this trial may inform future interventions and implementation policies designed to promote CRC screening in vulnerable patient populations and to reduce screening disparities.

The ASTRAL compendium provides several databases and tools to aid in the analysis of protein structures, particularly through the use of their sequences. Partially derived from the SCOP database of protein structure domains, it includes sequences for each domain and other resources useful for studying these sequences and domain structures. The current release of ASTRAL contains 54,745 domains, more than three times as many as the initial release four years ago. ASTRAL has undergone major transformations in the past two years. In addition to several complete updates each year, ASTRAL is now updated on a weekly basis with preliminary classifications of domains from newly released PDB structures. These classifications are available as a stand-alone database, as well as available integrated into other ASTRAL databases such as representative subsets. To enhance the utility of ASTRAL to structural biologists, all SCOP domains are now made available as PDB-style coordinate files as well as sequences. In addition to sequences and representative subsets based on SCOP domains, sequences and subsets based on PDB chains are newly included in ASTRAL. Several search tools have been added to ASTRAL to facilitate retrieval of data by individual users and automated methods.

The objective of this study was to develop comprehensive guidelines for medical care during mass gatherings based on the experience of providing medical support during rave parties. Study design was a prospective, observational study of self-referred patients who reported to First Aid Stations (FASs) during Dutch rave parties. All users of medical care were registered on an existing standard questionnaire. Health problems were categorized as medical, trauma, psychological, or miscellaneous. Severity was assessed based on the Emergency Severity Index. Qualified nurses, paramedics, and doctors conducted the study after training in the use of the study questionnaire. Total number of visitors was reported by type of event. During the 2006-2010 study period, 7,089 persons presented to FASs for medical aid during rave parties. Most of the problems (91.1%) were categorized as medical or trauma, and classified as mild. The most common medical complaints were general unwell-being, nausea, dizziness, and vomiting. Contusions, strains and sprains, wounds, lacerations, and blisters were the most common traumas. A small portion (2.4%) of the emergency aid was classified as moderate (professional medical care required), including two cases (0.03%) that were considered life-threatening. Hospital admission occurred in 2.2% of the patients. Fewer than half of all patients presenting for aid were transported by ambulance. More than a quarter of all cases (27.4%) were related to recreational drugs. During a five-year field research period at rave dance parties, most presentations on-site for medical evaluation were for mild conditions. A medical team of six healthcare workers for every 10,000 rave party visitors is recommended. On-site medical staff should consist primarily of first aid providers, along with nurses who have event-specific training on advanced life support, event-specific injuries and incidents, health education related to self-care deficits, interventions for psychological distress, infection control, and disaster medicine. Protocols should be available for treating common injuries and other minor medical problems, and for registration, triage, environmental surveillance and catastrophe management and response.

It is generally recognized that the AIDS epidemic will have a negative effect on the orphans’ school education. However, few studies have been carried out to examine the school performance and school behavior of AIDS orphans and vulnerable children (children living with HIV-infected parents). Using both self-report and teacher evaluation data of 1625 children from rural central China, we examined the impact of parental HIV/AIDS on children's school performances (academic marks, educational expectation, and student leadership) and school behaviors (e.g., aggression, shy/anxious and assertive social skills). Results indicate that AIDS orphans and vulnerable children had disadvantages in school performances in comparison to their peers from the same community who did not experience AIDS-related death and illness in their family (comparison children). AIDS orphans had the lowest academic marks based on the reports of both children and teachers. Educational expectation was significantly lower among AIDS orphans and vulnerable children than comparison children from teacher's perspective. AIDS orphans were significantly more likely to demonstrate aggressive, impulsive and anxious behaviors than non-orphans. Moreover, orphans have more learning difficulties. Vulnerable children were also at a disadvantage on most measures. The data suggest that a greater attention is needed to the school performance and behavior of children affected by AIDS. The findings also indicate that AIDS relief and assistance program for children should go beyond the school attendance and make efforts to improve their school performance and education aspiration.

2018-06-01

The aim of this study was to investigate if teaching patients about positioning before radiotherapy treatment would (a) reduce the residual rotational set-up errors, (b) reduce the number of repositionings and (c) improve patients' sense of control by increasing self-efficacy and reducing distress. Patients were randomized to either standard care (control group) or standard care and a teaching session combining visual aids and practical exercises (intervention group). Daily images from the treatment sessions were evaluated off-line. Both groups filled in a questionnaire before and at the end of the treatment course on various aspects of cooperation with the staff regarding positioning. Comparisons of residual rotational set-up errors showed an improvement in the intervention group compared to the control group. No significant differences were found in number of repositionings, self-efficacy or distress. Results show that it is possible to teach patients about positioning and thereby improve precision in positioning. Teaching patients about positioning did not seem to affect self-efficacy or distress scores at baseline and at the end of the treatment course.

Technical Study of a Standalone Photovoltaic–Wind Energy Based Hybrid Power Supply Systems for Island Electrification in Malaysia

2015-01-01

Energy is one of the most important factors in the socioeconomic development of a country. In a developing country like Malaysia, the development of islands is mostly related to the availability of electric power. Power generated by renewable energy sources has recently become one of the most promising solutions for the electrification of islands and remote rural areas. But high dependency on weather conditions and the unpredictable nature of these renewable energy sources are the main drawbacks. To overcome this weakness, different green energy sources and power electronic converters need to be integrated with each other. This study presents a battery storage hybrid standalone photovoltaic-wind energy power supply system. In the proposed standalone hybrid system, a DC-DC buck-boost bidirectional converter controller is used to accumulates the surplus hybrid power in the battery bank and supplies this power to the load during the hybrid power shortage by maintaining the constant dc-link voltage. A three-phase voltage source inverter complex vector control scheme is used to control the load side voltage in terms of the voltage amplitude and frequency. Based on the simulation results obtained from MATLAB/Simulink, it has been found that the overall hybrid framework is capable of working under variable weather and load conditions. PMID:26121032

To assess, with finite element analysis and an in vitro biomechanical study in cadaver, whether the implementation of an anterior interbody cage made of hedrocel with nitinol shape memory staples in compression increases the stiffness of the stand-alone interbody cage and to compare these constructs' stiffness to other constructs common in clinical practice. A biomechanical study with a finite element analysis and cadaveric testing assessed the stiffness of different fixation modes for the L4-L5 functional spinal unit: intact spine, destabilized spine with discectomy, posterior pedicle-screw fixation, anterior stand-alone interbody cage, anterior interbody cage with bilateral pedicle screws and anterior interbody cage with two shape memory staples in compression. These modalities of vertebral fixation were compared in four loading modes (flexion, extension, lateral bending, and axial rotation). The L4-L5 spinal unit with an anterior interbody cage and two staples was stiffer than the stand-alone cage. The construct stiffness was similar to that of a model of posterior pedicular stabilization. The stiffness was lower than that of the anterior cage plus bilateral pedicle-screw fixation. The use of an anterior interbody implant with shape memory staples in compression may be an alternative to isolated posterior fixation and to anterior isolated implants, with increased stiffness.

Energy is one of the most important factors in the socioeconomic development of a country. In a developing country like Malaysia, the development of islands is mostly related to the availability of electric power. Power generated by renewable energy sources has recently become one of the most promising solutions for the electrification of islands and remote rural areas. But high dependency on weather conditions and the unpredictable nature of these renewable energy sources are the main drawbacks. To overcome this weakness, different green energy sources and power electronic converters need to be integrated with each other. This study presents a battery storage hybrid standalone photovoltaic-wind energy power supply system. In the proposed standalone hybrid system, a DC-DC buck-boost bidirectional converter controller is used to accumulates the surplus hybrid power in the battery bank and supplies this power to the load during the hybrid power shortage by maintaining the constant dc-link voltage. A three-phase voltage source inverter complex vector control scheme is used to control the load side voltage in terms of the voltage amplitude and frequency. Based on the simulation results obtained from MATLAB/Simulink, it has been found that the overall hybrid framework is capable of working under variable weather and load conditions.

To assess the influence of orphanhood due to AIDS on children's nutritional status, psychological well-being and life quality, and to explore appropriate intervention strategies in China. In 2005, 186 children aged 8-15 years (93 AIDS orphans and 93 non-orphans) from a rural area of Henan Province were surveyed in a cross-sectional and matched pairs study on nutritional status, psychological health and life quality. We found no compelling evidence for poorer nutritional status in orphans. The nutritional status of both orphans and non-orphans was extremely poor according to the prevalence of stunting, underweight, wasting and anaemia. Depression, low self-esteem and lower quality of life were more frequent in orphans. These differences mainly existed in boys' groups. No significant differences were found between paternal, maternal and double orphans, or orphans in orphanages or extended families. Regression analysis revealed that orphanhood leads to low self-esteem and more depression which contributes to lower quality of life and mediates the association between orphanhood and quality of life. The high prevalence of poor nutritional status indicates that basic material needs of children, including AIDS orphans, are not met in rural China. Psychological problems were prominent among orphans and had become the most important contributor of lower life quality. Boys were at least as vulnerable as girls. The living conditions of all children in rural China must be improved; school-based care and support are crucial and would be a cost-effective way to improve the overall life quality of AIDS orphans.

Drama advertisements: moderating effects of self-relevance on the relations among empathy, information processing, and attitudes.

The effects of drama versus lecture format in public service advertisements are studied in a 2 (format) x 2 (malaria vs AIDS) factorial design. Two structural equation models are built (one for each level of self-relevance), showing two distinct patterns. In both low and high self-relevant situations, empathy plays a key role. Under low self-relevance conditions, drama enhances information processing through empathy. Under high self-relevant conditions, the advertisement format has neither significant cognitive or empathetic effects. The information processing generated by the highly relevant topic affects viewers' empathy, which in turn affects the attitude the advertisement and the behavioral intent. As predicted by the Elaboration Likelihood Model, the advertisement format enhances the attitudes and information processing mostly under low self-relevant conditions. Under low self-relevant conditions, empathy enhances information processing while under high self-relevance, the converse relation holds.

The main purpose of this study was to discuss the nationality differences of foreign nurse aides and the effect of work stressors influencing work adjustment. And of helping them adapt to Taiwanese society, we summarized the difficulties that foreign nurse aides face in Taiwan. The subjects included 80 foreign nurse aides from the Philippines, Indonesia, and Vietnam who worked in long-term care facilities in Tao Yuan County. We recruited volunteers at the participating facilities to complete the anonymous questionnaires. The return rate of the questionnaire was 88.75%. The validated instruments of Hershenson's (1981) and Schaefer and Moos (1993) were adopted to measure work stressors and work adjustment, respectively. A forward-backward translation process was used in this study. Indonesian foreign nurse aides respect their work, and are better workers than Vietnamese and Filipino nurse aids in many respects, which shows how the nationality of the foreign nurse aides might affect work adjustment. The stress created from patient care tasks influenced the foreign nurse aides' personal relationships at work and also affected their attitude when they performed their tasks. In addition, pressure from their supervisors might have affected their work skills, work habits, personal relationships, self-concepts or work attitudes. Moreover, a heavy workload and improper scheduling might have affected the personal relationships and work attitudes of the foreign nurse aides. It was found that work stressors had a significant correlation with work adjustment. The results of the present study indicate that training programs are important factors for work adjustment among foreign nurse aides. Furthermore, celebration and leisure activities could be provided to release them from work stressors. More effort should be put into improving the working environment, namely providing a more supportive and enriching atmosphere. Based on these findings, we have a better understanding of how to assist foreign nurse aides in the future.

In Ethiopia, more adolescents are in school today than ever before; however, there are no studies that have assessed their comprehensive knowledge of HIV/AIDS. Thus, this study tried to assess the level of this knowledge and the factors associated with it among in-school adolescents in eastern Ethiopia. A cross-sectional school-based study was conducted using a facilitator-guided self-administered questionnaire. The respondents were students attending regular school in 14 high schools located in 14 different districts in eastern Ethiopia. The proportion of in-school adolescents with comprehensive HIV/AIDS knowledge was computed and compared by sex. The factors that were associated with the comprehensive HIV/AIDS knowledge were assessed using bivariate and multivariable logistic regression. Only about one in four, 677 (24.5%), in-school adolescents have comprehensive HIV/AIDS knowledge. The knowledge was better among in-school adolescents from families with a relatively middle or high wealth index (adjusted OR [95% CI]=1.39 [1.03-1.87] and 1.75 [1.24-2.48], respectively), who got HIV/AIDS information mainly from friends or mass media (adjusted OR [95% CI]=1.63 [1.17-2.27] and 1.55 [1.14-2.11], respectively) and who received education on HIV/AIDS and sexual matters at school (adjusted OR [95% CI]=1.59 [1.22-2.08]). The females were less likely to have comprehensive HIV/AIDS knowledge compared to males (adjusted OR and [95% CI]=0.60 [0.49-0.75]). In general, only about a quarter of in-school adolescents had comprehensive HIV/AIDS knowledge. Although the female adolescents are highly vulnerable to HIV infection and its effects, they were by far less likely to have comprehensive HIV/AIDS knowledge. HIV/AIDS information, education and communication activities need to be intensified in high schools.

Adolescents report high asthma-related morbidity that can be prevented by adequate self-management of the disease. Therefore, there is a need for a developmentally appropriate strategy to promote effective asthma self-management. Mobile phone-based technology is portable, commonly accessible, and well received by adolescents. The purpose of this study was to develop and evaluate the feasibility and acceptability of a comprehensive mobile phone-based asthma self-management aid for adolescents (mASMAA) that was designed to facilitate symptom monitoring, treatment adherence, and adolescent-parent partnership. The system used state-of-the-art natural language-understanding technology that allowed teens to use unconstrained English in their texts, and to self-initiate interactions with the system. mASMAA was developed based on an existing natural dialogue system that supports broad coverage of everyday natural conversation in English. Fifteen adolescent-parent dyads participated in a 2-week trial that involved adolescents' daily scheduled and unscheduled interactions with mASMAA and parents responding to daily reports on adolescents' asthma condition automatically generated by mASMAA. Subsequently, four focus groups were conducted to systematically obtain user feedback on the system. Frequency data on the daily usage of mASMAA over the 2-week period were tabulated, and content analysis was conducted for focus group interview data. Response rates for daily text messages were 81%-97% in adolescents. The average number of self-initiated messages to mASMAA was 19 per adolescent. Symptoms were the most common topic of teen-initiated messages. Participants concurred that use of mASMAA improved awareness of symptoms and triggers, promoted treatment adherence and sense of control, and facilitated adolescent-parent partnerships. This study demonstrates the utility and user acceptability of mASMAA as a potential asthma self-management tool in a selective group of adolescents. Further research is needed to replicate the findings in a large group of adolescents from sociodemographically diverse backgrounds to validate the findings.

This qualitative study explored the impact on oral health-care knowledge, attitudes, and practices among 39 people living with HIV/AIDS (PLWHA) participating in a national initiative aimed at increasing access to oral health care. Personal values and childhood dental experiences, beliefs about the importance of oral health in relation to HIV health, and concerns for appearance and self-esteem were found to be determinants of oral health knowledge and practice. Program participation resulted in better hygiene practices, improved self-esteem and appearance, relief of pain, and better physical and emotional health. In-depth exploration of the causes for these changes revealed a desire to continue with dental care due to the dental staff and environmental setting, and a desire to maintain overall HIV health, including oral health. Our findings emphasize the importance of addressing both personal values and contextual factors in providing oral health-care services to PLWHA. PMID:22547879

This study investigates whether using an HIV/AIDS symptom management manual with self-care strategies for 21 common symptoms, compared to a basic nutrition manual, had an effect on reducing symptom frequency and intensity. A 775-person, repeated measures, randomized controlled trial was conducted over three months in 12 sites from the United States, Puerto Rico, and Africa to assess the relationship between symptom intensity with predictors for differences in initial symptom status and change over time. A mixed model growth analysis showed a significantly greater decline in symptom frequency and intensity for the group using the symptom management manual (intervention) compared to those using the nutrition manual (control) (t=2.36, P=0.018). The models identified three significant predictors for increased initial symptom intensities and in intensity change over time: (1) protease inhibitor-based therapy (increased mean intensity by 28%); (2) having comorbid illness (nearly twice the mean intensity); and (3) being Hispanic receiving care in the United States (increased the mean intensity by 2.5 times). In addition, the symptom manual showed a significantly higher helpfulness rating and was used more often compared to the nutrition manual. The reduction in symptom intensity scores provides evidence of the need for palliation of symptoms in individuals with HIV/AIDS, as well as symptoms and treatment side effects associated with other illnesses. The information from this study may help health care providers become more aware of self-management strategies that are useful to persons with HIV/AIDS and help them to assist patients in making informed choices.

Priming by a novel universal influenza vaccine (Multimeric-001)-a gateway for improving immune response in the elderly population.

A new vaccine, "Multimeric-001" (M-001) has been recently developed, containing conserved, common linear influenza epitopes that activate both cellular and humoral arms of the immune system against a wide variety of influenza A and B strains. Apart from its direct action, M-001 is an attractive candidate for priming immune responses to seasonal influenza vaccine for the elderly population. The current clinical study was designed to assess M-001's standalone and priming action in participants over 65 years old. Evaluation of standalone action is based on induction of cell mediated immunity (CMI), since M-001 alone does not induce hemagglutinin inhibition (HAI) antibodies. This was a two-center, randomized, placebo-controlled study. 120 participants were randomized 1:1:1:1 into four groups to receive either two sequential non-adjuvanted or a single non-adjuvanted or a single adjuvanted intramuscular injection of 500 mcg M-001 (treatment), or one placebo (saline) injection, before receiving the trivalent inactivated influenza vaccine (TIV). Due to visual differences between placebo and treatment the study was partially blinded. HAI was evaluated at baseline and 3 weeks after standard TIV vaccination as a measure of M-001's efficacy. CMI responses were evaluated in a subset (10/group) of the participants. Participants were monitored for safety throughout the study. Overall the treatment was well-tolerated and safe, though sample sizes allowed only limited statistical analysis. M-001 priming resulted in enhanced seroconversion towards all three TIV strains, compared to priming with placebo. Significant elevation of influenza-specific CMI was observed following immunization with M-001 alone. The standalone and priming actions of M-001 were demonstrated in elderly participants despite the limitations of small population size and pre-existing HAI antibody titers in some participants. As a standalone vaccine, M-001 induced significant CMI to multiple strains and as a primer, M-001 enhanced HAI responses. Larger scale studies are warranted. NCT01419925.

[Information, attitudes, perceptions, and symbolic representations of AIDS risk and prevention among poor adolescents in Rio de Janeiro, Brazil].

PubMed

Merchán-Hamann, E

1995-01-01

Four hundred and sixteen poor adolescents of both sexes in Rio de Janeiro were interviewed to study both their level of information and symbolic representations concerning AIDS risk and prevention. The most common source of information on HIV/AIDS was the mass media, particularly television broadcasts. There were doubts and lack of trust regarding official government information on HIV/AIDS. Nearly 70% of the adolescents interviewed believe in HIV transmission through mosquito bites and some 40% through casual contact with wounds or scars or sharing of bathroom utensils. Men seemed to show a greater awareness and autonomy vis- -vis taking initiatives in sex encounters. Attitudes of segregation and exclusion of people with AIDS persist. Lack of prevention was attributed to the impossibility of predicting sexual encounters. The study of symbolic aspects concerning causes of HIV/AIDS displayed broad variability: 80% of the interviewees associated AIDS with excesses in sexual behavior and 40% with homosexual practices. Causal images vary from the predominant view of AIDS as unfair punishment to the less frequent stance considering AIDS as fair punishment (due to sinful behavior). An ambiguous attitude towards transgression (taking as its sterotype the figure of Rio's "malandro", or "streetwise dude") may influence perception of risk and prevention. The paper calls attention to the need for implementing clearer and more direct educational programs. This could be useful for the implementation of culturally sensitive control measures through a reshaping of AIDS symbols. The author recommends a better understanding of the social and economic determinants of disease and reinforcement of the kinds of discourse which empower and raise the self-esteem of poor adolescents by endorsing their civil rights.

Quantification of Hepatorenal Index for Computer-Aided Fatty Liver Classification with Self-Organizing Map and Fuzzy Stretching from Ultrasonography.

2015-01-01

Accurate measures of liver fat content are essential for investigating hepatic steatosis. For a noninvasive inexpensive ultrasonographic analysis, it is necessary to validate the quantitative assessment of liver fat content so that fully automated reliable computer-aided software can assist medical practitioners without any operator subjectivity. In this study, we attempt to quantify the hepatorenal index difference between the liver and the kidney with respect to the multiple severity status of hepatic steatosis. In order to do this, a series of carefully designed image processing techniques, including fuzzy stretching and edge tracking, are applied to extract regions of interest. Then, an unsupervised neural learning algorithm, the self-organizing map, is designed to establish characteristic clusters from the image, and the distribution of the hepatorenal index values with respect to the different levels of the fatty liver status is experimentally verified to estimate the differences in the distribution of the hepatorenal index. Such findings will be useful in building reliable computer-aided diagnostic software if combined with a good set of other characteristic feature sets and powerful machine learning classifiers in the future.

Population-based routine service screening has gained popularity following an era of randomized controlled trials. The evaluation of these service screening programs is subject to study design, data availability, and the precise data analysis for adjusting bias. We developed a computer-aided system that allows the evaluation of population-based service screening to unify these aspects and facilitate and guide the program assessor to efficiently perform an evaluation. This system underpins two experimental designs: the posttest-only non-equivalent design and the one-group pretest-posttest design and demonstrates the type of data required at both the population and individual levels. Three major analyses were developed that included a cumulative mortality analysis, survival analysis with lead-time adjustment, and self-selection bias adjustment. We used SAS AF software to develop a graphic interface system with a pull-down menu style. We demonstrate the application of this system with data obtained from a Swedish population-based service screen and a population-based randomized controlled trial for the screening of breast, colorectal, and prostate cancer, and one service screening program for cervical cancer with Pap smears. The system provided automated descriptive results based on the various sources of available data and cumulative mortality curves corresponding to the study designs. The comparison of cumulative survival between clinically and screen-detected cases without a lead-time adjustment are also demonstrated. The intention-to-treat and noncompliance analysis with self-selection bias adjustments are also shown to assess the effectiveness of the population-based service screening program. Model validation was composed of a comparison between our adjusted self-selection bias estimates and the empirical results on effectiveness reported in the literature. We demonstrate a computer-aided system allowing the evaluation of population-based service screening programs with an adjustment for self-selection and lead-time bias. This is achieved by providing a tutorial guide from the study design to the data analysis, with bias adjustment. Copyright © 2010 Elsevier Inc. All rights reserved.

In China, migrants with acquired immunodeficiency syndrome (AIDS) have become a serious problem in the field of AIDS prevention. This study aimed to evaluate the efficacy of interventions for human immunodeficiency virus (HIV) infection prevention for migrants in China and to identify factors associated with intervention efficacy. A computerized literature search of the Chinese National Knowledge Infrastructure, Wan Fang, and PubMed databases was conducted to collect related articles published in China. Only self-control intervention studies or studies containing sections regarding self-control interventions wherein the method of intervention was health education were included. Rev Manager 5.3 software was used to analyze the intervention effects in terms of knowledge, attitude, and behavior indexes. Relative to pre-intervention, the HIV interventions showed statistically significant efficacy in terms of sexual transmission of HIV, condom use for HIV prevention, change in attitude towards HIV/AIDS patients, incidence of commercial sex behavior, and recent condoms use during sex (P < .01). Moreover, the baseline rate of migrants, intervention time, peer education, region, and education background were factors influencing the efficacy of the intervention. Significant improvement in terms of knowledge of sexual transmission of HIV and attitudes and behaviors among migrants was observed; however, based on the findings of previous studies, the interventions should be customized for different people from different districts in China. Further research is needed to evaluate subgroups of migrants in China according to their baseline characteristics.

Objectives: There is preliminary evidence for the efficacy of positive psychology interventions for pain management. The current study examined the effects of an internet-based positive psychology self-help program for patients with chronic musculoskeletal pain and compared it with an internet-based cognitive-behavioral program. Materials and Methods: A randomized controlled trial was carried out with 3 conditions: an internet-delivered positive psychology program, an internet-delivered cognitive-behavioral program and waitlist control. A total of 276 patients were randomized to 1 of the 3 conditions and posttreatment data were obtained from 206 patients. Primary outcomes were happiness, depression, and physical impairments at posttreatment and at 6-month follow-up. Intention-to-treat analyses were carried out using mixed regression analyses. Results: Both treatments led to significant increases in happiness and decreases in depression. Physical impairments did not significantly decrease compared with waitlist. Improvements in happiness and depression were maintained until 6-month follow-up. There were no overall differences in the efficacy of the 2 active interventions but effects seemed to be moderated by education. Patients with a higher level of education profited slightly more from the positive psychology intervention than from the cognitive-behavioral program. Discussion: The results suggest that an internet-based positive psychology and cognitive-behavioral self-help interventions for the management of chronic pain are clinically useful. Because the self-help exercises as used in the current program do not require therapist involvement, dissemination potential is large. Further studies should examine whether it can best be used as stand-alone or add-on treatment combined with established pain treatment programs. PMID:28379873

Ten to thirty percent of lung cancer is thought to be of occupational origin. Lung cancer is under-declared as an occupational disease in Europe, and most declarations of occupational disease concern asbestos. The purpose of this study was to design and validate a short, sensitive self-administered questionnaire, as an aid for physicians in detecting occupational exposure to asbestos and other lung carcinogens in order to remedy occupational lung cancer under-declaration. Cross-sectional study. A short (30-question) self-administered questionnaire was drawn up by oncologist-pneumologists and occupational physicians, covering situations of exposure to proven and probable lung carcinogens. Understanding and acceptability were assessed on 15 lung cancer patients. Validity and reliability were assessed on 70 lung cancer patients by comparison against a semi-directive questionnaire considered as gold standard. Sensitivity and specificity were assessed by comparing responses to items on the two questionnaires. Reliability was assessed by analysing the kappa concordance coefficient for items on the two questionnaires. Sensitivity was 0.85 and specificity 0.875. Concordance between responses on the two questionnaires was 85.7%, with a kappa coefficient of 0.695 [0.52-0.87]. Mean self-administration time was 3.1 min (versus 8.12 min to administer the gold-standard questionnaire). In 16 patients, the self-administered questionnaire detected lung carcinogen exposure meeting the criteria for occupational disease. The present short, easy-to-use self-administered questionnaire should facilitate detection of occupational exposure to lung carcinogens. It could be used in occupational lung cancer screening and increase the presently low rate of application for recognition of lung cancer as an occupational disease.

African-Americans and Hispanics are disproportionately affected by HIV/AIDS in the United States. HIV infection is often acquired during adolescence, a time when risky sexual behaviors are at their peak. This study explored relationships among selected risk factors, protective factors, and risky sexual behaviors among African-American, Hispanic, and White adolescents, from a sample of adolescents from the National Longitudinal Study of Adolescent Health. African-Americans and Hispanics were more likely to have sexual intercourse without the use of birth control than were Whites. African-Americans were more likely to have sexual behavior with multiple sexual partners than either Hispanics or Whites were, and African-Americans had higher self-esteem than did Hispanics and Whites. In order to develop culturally sensitive, effective interventions to prevent HIV/AIDS in adolescents, racial differences in risk and protective factors must be examined.

Hopelessly mortal: The role of mortality salience, immortality and trait self-esteem in personal hope.

PubMed

Wisman, Arnaud; Heflick, Nathan A

2016-08-01

Do people lose hope when thinking about death? Based on Terror Management Theory, we predicted that thoughts of death (i.e., mortality salience) would reduce personal hope for people low, but not high, in self-esteem, and that this reduction in hope would be ameliorated by promises of immortality. In Studies 1 and 2, mortality salience reduced personal hope for people low in self-esteem, but not for people high in self-esteem. In Study 3, mortality salience reduced hope for people low in self-esteem when they read an argument that there is no afterlife, but not when they read "evidence" supporting life after death. In Study 4, this effect was replicated with an essay affirming scientific medical advances that promise immortality. Together, these findings uniquely demonstrate that thoughts of mortality interact with trait self-esteem to cause changes in personal hope, and that literal immortality beliefs can aid psychological adjustment when thinking about death. Implications for understanding personal hope, trait self-esteem, afterlife beliefs and terror management are discussed.

Through group identification, mutual support, and modeling, behavior is directed toward learning a new coping life style. The self-help group model is considered here as a viable and necessary part of a total rehabilitation service system. (Author)

Multiple randomized controlled trials (RCTs) show that behavioral lifestyle interventions are effective in improving diabetes management and that comprehensive risk factor management improves cardiovascular disease (CVD) outcomes. The role of technology has been gaining strong support as evidence builds of its potential to improve diabetes management; however, evaluation of its impact in minority populations is limited. This study intends to provide early evidence of a theory-driven intervention, Tablet-Aided BehavioraL intervention EffecT on Self-management skills (TABLETS), using real-time videoconferencing for education and skills training. We examine the potential for TABLETS to improve health risk behaviors and reduce CVD risk outcomes among a low-income African American (AA) population with poorly controlled type 2 diabetes. The study is a two-arm, pilot controlled trial that randomizes 30 participants to the TABLETS intervention and 30 participants to a usual care group. Blinded outcome assessments will be completed at baseline, 2.5 months (immediate post-intervention), and 6.5 months (follow-up). The TABLETS intervention consists of culturally tailored telephone-delivered diabetes education and skills training delivered via videoconferencing on tablet devices, with two booster sessions delivered via tablet-based videoconferencing at 3 months and 5 months to stimulate ongoing use of the tablet device with access to intervention materials via videoconferencing slides and a manual of supplementary materials. The primary outcomes are physical activity, diet, medication adherence, and self-monitoring behavior, whereas the secondary outcomes are HbA1c, low-density lipoprotein cholesterol (LDL-C), BP, CVD risk, and quality of life. This study provides a unique opportunity to assess the feasibility and efficacy of a theory-driven, tablet-aided behavioral intervention that utilizes real-time videoconferencing technology for education and skills training on self-management behaviors and quality of life among a high-risk, low-income AA population with an uncontrolled dyad or triad of CVD risk factors (diabetes with or without hypertension or hyperlipidemia). The intervention leverages the use of novel technology for education and skill-building to foster improved diabetes self-management. The findings of this study will inform the process of disseminating the intervention to a broader and larger sample of people and can potentially be refined to align with clinical workflows that target a subsample of patients with poor diabetes self-management. The trial was registered in April 2014 with the United States National Institutes of Health Clinical Trials Registry (ClinicalTrials.gov identifier NCT02128854), available online at: http://clinicaltrials.gov/ct2/show/NCT02128854 .
