Views on dignity in providing health care for older people.

PubMed

Calnan, Michael; Woolhead, Gillian; Dieppe, Paul; Tadd, Win

The aim of this study was to explore the salience and meaning of dignity and dignified care for care providers and the implications for the proviosion of care. The project forms part of an international study being undertaken in different European countries comparing health and social care workers' views on dignity. Focus groups were chosen as the primary method of data collection. Twelve focus groups were carried out involving a total of 52 participants representing a range of occupational groups. All participants stated that dignity and respect were important for people of all age groups. The evidence that emerged from these focus groups showed that, in spite of the appropriate intentions of providers, older people were not consistently provided with dignified care. In order to ensure dignity in providing care for older people, tasks need to be organised around older people's needs and time frames. Without such changes there is a danger that 'institutional ageism' will persist in the health service.

Children with additional support needs (ASNs) often require physiotherapy intervention to help maximise their participation within the primary school setting. The aim of this research was to investigate paediatric physiotherapy practice in supporting primary school aged children with ASNs, in order to identify a language to describe this, which could be used to support communication with teachers, parents and others outside the profession. Using a qualitative research multiple methods design, 2 focus groups and 5 structured interviews were held to investigate physiotherapy practice for this group. Senior paediatric physiotherapists (n=13) from a range of specialities, with experience of supporting primary school aged children with ASNs. Focus groups and interviews were digitally recorded, transcribed verbatim and analysed to establish links and patterns: followed by a cyclical process of respondent validation, and expert review. Eight targets for physiotherapy intervention and twelve technique headings were synthesised from the data. The language used for labelling and description of these was aimed to be easily understood by colleagues outside the profession. The findings clearly identified the role of the paediatric physiotherapist as being to support primary school aged children with ASNs to acquire aspects of postural control, mobility and cardio-respiratory function. By grouping the data into eight areas of challenge as the focus of intervention, and twelve commonly used techniques, the researchers generated a language which can be used by paediatric physiotherapists to support communication with teachers, parents and others outside the profession, when describing their intent and interactions regarding these children.

2009-11-01

To use focus groups to inform a web-based educational intervention for increased fruit and vegetable (FV) consumption. Twelve groups (participants=137, aged 21-65) were recruited from four geographically diverse health systems. Four groups were stratified by gender and eight by race (white and African American) and gender. Questions included perceptions of healthy eating, factors that encourage or serve as barriers to FV consumption and features preferred for a web-based educational intervention. Though knowledgeable about healthy eating, participants did not know how to achieve or always care about healthy nutritional choices. Motivators for FV consumption included being role models and health concerns. Barriers included: lack of time, expense and FV availability. Website preferences included: visuals, links, tailored materials, menu suggestions, goal setting assistance, printable summaries and built in motivation. The developers incorporated nearly all suggestions. Focus groups provided needs-based tactical strategies for an online, education intervention targeting factors to improve FV consumption. Focus groups can provide valuable input to inform interventions. Further, web-based programs' abilities to offer information without time or geographic constraints, with capacity for tailoring and tracking progress makes them a valuable addition in the arsenal of efforts to promote healthy behaviors.

Evaluation of pain and function after two home exercise programs in a clinical trial on women with chronic neck pain - with special emphasises on completers and responders

PubMed Central

2014-01-01

Background Different types of exercises can help manage chronic neck pain. Supervised exercise interventions are widely used, but these protocols require substantial resources. The aim of this trial, which focused on adherence, was to evaluate two home exercise interventions. Methods This parallel group randomized controlled trial included 57 women randomly allocated into two groups – a strength training group (STRENGTH, 34 subjects) and a stretching group (STRETCH, 23 subjects). The interventions focused on the neck and shoulder muscles and lasted for 12 months. The STRENGTH group performed weight training and ended each session with stretching exercises. These stretching exercises constituted the entirety of the STRETCH group’s training session. Both groups were instructed to exercise three times per week. All the participants kept an exercise diary. In addition, all participants were offered support via phone and e-mail. The primary outcomes were pain intensity and function. The trial included a four- to six-month and a twelve-month follow-up. A completer in this study exercised at least 1,5 times per week during eight unbroken weeks. A responder in this study reported clinically significant improvements on pain and function. The statistical analyses used the Mann Whitney U-test, Wilcoxon signed-rank test, and X 2 test. Results At four- to six-months, the numbers of completers were 19 in the STRENGTH group and 17 in the STRETCH group. At twelve months, the corresponding numbers were 11 (STRENGTH) and 10 (STRETCH). At four- to six-months, the proportions of subjects reporting clinically important changes (STRENGTH and STRETCH) were for neck pain: 47% and 41%, shoulder pain: 47% and 47%, function: 37% and 29%. At twelve months, the corresponding numbers were for neck pain: 45% and 40%, shoulder pain: 55% and 50%, function: 55% and 20%. Conclusions No differences in the two primary outcomes between the two interventions were found, a finding that may be due to the insufficient statistical power of the study. Both interventions based on home exercises improved the two primary outcomes, but the adherences were relatively low. Future studies should investigate ways to improve adherence to home exercise treatments. Trial registration ClinicalTrials.gov Id: NCT01876680 PMID:24400934

Fungi are eukaryotic microorganisms including yeast and molds. Many studies have focused on modifying bacterial growth, but few on fungal growth. Microcurrent electricity may stimulate fungal growth. This study aims to investigate effects of microcurrent electric stimulation on Trichophyton rubrum growth. Standard-sized inoculums of T. rubrum derived from a spore suspension were applied to potato dextrose cornmeal agar (PDACC) plates, gently withdrawn with a sterile pipette, and were applied to twelve PDACC plates with a sterile spreader. Twelve Petri dishes were divided into four groups. The given amperage of electric current was 500 nA, 2 µA, and 4 µA in groups A, B, and C, respectively. No electric current was given in group D. In the first 48 hours, colonies only appeared in groups A and B (500 nA and 2 µA exposure). Colonies in group A (500 nA) were denser. Group C (4 µA) plates showed a barely visible film of fungus after 96 hours of incubation. Fungal growth became visible after 144 hours in the control group. Lower intensities of electric current caused faster fungal growth within the amperage range used in this study. Based on these results, further studies with a larger sample size, various fungal species, and various intensities of electric stimulation should be conducted.

The aim of this study was to determine the feasibility and safety of high intensity focused ultrasound's (HIFU) in pancreatic diseases. Twelve pigs were divided into three groups. The pancreases of pigs in Group A were ablated directly with HIFU, but those in Group B and C ablated by extracorporeal HIFU. The pigs in Group C were sacrificed at day 7 after HIFU. Serological parameters were determined pre-operation and post-operation. The entire pancreas was removed for histological examination. Each animal tolerate the HIFU ablation well. The complete necrosis was observed in targeted regions. The margins of the necrotic regions were clearly delineated from the surrounding normal tissues. Infiltration of inflammatory cells and phorocytosis on the boundary were found in group C. Blood and urine amylase levels were relatively steady after HIFU. No acute pancreatitis or severe complications occurred. In conclusion, HIFU ablation on the pancreas was safe and effective in experimental pigs.

Twelve Sangomas or traditional healers participated in a focus group exploring their understanding of cervical cancer and human papilloma virus (HPV), their role informing women about cervical cancer prevention and screening; and their interaction/cooperation with western medicine. Participants lacked knowledge of HPV and the HPV vaccine but had an understanding of cervical cancer prevention and pap smears. Participants expressed interest in greater collaboration with western doctors, requested more prevention information, and noted the vaccine could serve as strategy to prevent HPV in victims of sexual violence, and time of vaccination could serve as an opportunity for parents to talk to their children about sex.

Nadeau, Melanie; Blake, Norby; Poupart, John; Rhodes, Kristine; Forster, Jean L

2012-11-01

Circles of Tobacco Wisdom (CTW) was an elder-led, community-based project that aimed to enhance tobacco control in the American Indian community. Its goal was to provide elders with the knowledge, opportunities, and support to enable them to assume leadership of a tobacco control movement that was grounded in the ceremonial traditions of tobacco use. The purpose of this study was to test the effects of the pilot intervention on participants. The design of this pilot study intervention was a single group, pre-post comparison, with a pre-post survey, monthly check-ins, and a post-1-year focus group. Twelve elders were included in the pre- and post-analyses. All twelve elders were women who self-identified as American Indian (mean age = 64). The CTW elders participated in monthly talking circles, quarterly learning sessions, and a post-1-year focus group, and took part in other learning, support, and community action opportunities. Data were collected from December 2008 through November 2009 and analyzed throughout the process. American Indian Elders' tobacco-related knowledge, perceptions, beliefs, and behaviors were measured while participating in the CTW project. Knowledge, perceptions, beliefs, and behavior changes were seen with cigarette smoking, secondhand smoke, and ceremonial tobacco use and risk perception. After 6 months, the number of people the elders had talked with about tobacco increased, elders were more likely to have a discussion on tobacco at a community event, and their comfort level talking about commercial and traditional tobacco also increased. A number of themes also were identified in the focus group: feeling more comfortable talking about tobacco issues, learning a lot about traditional and commercial tobacco, and realizing the dangers of smoking. Elders increased their knowledge about commercial and traditional tobacco and changed related attitudes as a result of CTW. Further, American Indian Elders perceived that CTW was effective.

Focus on Exercise: Client and Clinician Perspectives on Exercise in Individuals with Serious Mental Illness.

PubMed

Browne, Julia; Mihas, Paul; Penn, David L

2016-05-01

The health benefits of exercise are well established, yet individuals with serious mental illness (SMI) have a shorter life expectancy due in large part to physical health complications associated with poor diet and lack of exercise. There is a paucity of research examining exercise in this population with the majority of studies having examined interventions with limited feasibility and sustainability. Before developing an intervention, a thorough exploration of client and clinician perspectives on exercise and its associated barriers is warranted. Twelve clients and fourteen clinicians participated in focus groups aimed at examining exercise, barriers, incentives, and attitudes about walking groups. Results indicated that clients and clinicians identified walking as the primary form of exercise, yet barriers impeded consistent participation. Distinct themes arose between groups; however, both clients and clinicians reported interest in a combination group/pedometer based walking program for individuals with SMI. Future research should consider examining walking programs for this population.

Introducing a checking technician allows pharmacists to spend more time on patient-focused activities.

PubMed

Napier, Patti; Norris, Pauline; Braund, Rhiannon

2018-04-01

Internationally there is an increasing focus on the clinical and cognitive services that pharmacists can provide. Lack of time has been identified as a barrier to pharmacists increasing their clinical activities. Within the pharmacy workplace there are many tasks that can only be performed by a pharmacist. The final accuracy check of a dispensed prescription is currently the sole responsibility of pharmacists in New Zealand. This takes up a significant amount of time during a pharmacist's work day. The introduction of a checking technician role has been suggested to allow pharmacists more time to do more patient focused work. To investigate the amount of time pharmacy staff spend on specific activities and to establish whether the introduction of a checking technician into twelve pilot sites increased the amount of time that the pharmacists could spend on patient focused activities. This study utilised a self-reported work sampling technique in twelve pilot sites, selected from both the hospital and community settings. Work sampling using an electronic device was conducted at two time-points (before the implementation of a Pharmacy Accuracy Checking Technician (PACT) role and when the PACT was in place). Data was collected at 10 min intervals for the period of five days, a working week. Tasks were grouped into patient focused, dispensing and personal activities. The introduction of the PACT into the pilot sites saw a mean increase of 19% in pharmacists' patient focused activities and a mean 20% decrease in dispensing activities. The introduction of a checking technician role into New Zealand pharmacies demonstrated the potential to provide pharmacists with more time to spend on patient focused activities.

Prematurity is a public health problem that calls to focus on its causes and consequences through a trans disciplinary approach. There are no studies analyzing premature birth from the perspective of individuals born preterm. To identify social representations associated with premature birth of individuals born preterm in the 1990s in Argentina. Twelve focus groups were conducted with individuals born preterm with a birth weight<1500 g assisted at tertiary care facilities between 1990 and 1995. Focus group contents were analyzed based on the social representation theory. Fifty-nine adolescents and youth participated; their median age was 18.5±2.3 years old. Based on the analysis of focus groups, six core themes were developed: life experience, parents' memories and experiences, overprotection body, education, relationship with the medical practice and knowledge. The methodology used allowed to create a space for mutual recognition and reflection for participants. Prematurity is a significant element, especially in those who suffered major sequelae. Adolescents and youth give a warning on the negative effects caused by overprotective parents and reveal the possibility of redefining the challenges associated with their history of premature birth.

Synthesis of hydrazone functionalized epoxy polymers for non-linear optical device applications

NASA Astrophysics Data System (ADS)

Singh, Rajendra K.

A series of twelve, thermally crosslinkable, epoxy polymers bearing covalently attached NLO-active hydrazone chromophores were synthesized. The primary focus was on the synthesis of two series of NLO-active hydroxy functionalized hydrazone chromophores. The first series, called the monohydroxy series (Hydrazones I--VI) comprised of six monohydroxy functionalized hydrazones and the second series consisted of six dihydroxy functionalized hydrazones (Hydrazones VII--XII). These hydrazone chromophores were then grafted, via the hydroxy functionality, on to a commercial epoxy polymer to obtain twelve NLO-active soluble prepolymers. The grafting reaction yields multiple secondary hydroxyl sites due to opening of the epoxide rings and these hydroxyl groups were used for further crosslinking by formulating the prepolymers with a blocked polyisocyanate commercial crosslinker. This formulation was spin coated on glass slides to form 2--2.5 m m thick uniform, defect free, transparent films. The films were corona poled, above their Tg, to align the chromophores in a noncentrosymmetric fashion and simultaneously complete the thermal cure that results in a highly crosslinked network. Finally the thermal characteristics of the second order nonlinearity of the twelve polymers are compared to illustrate the key structure-property relationships underlying the performance of the films.

2016-01-01

The Global Hydrology Resource Center (GHRC; ghrc.nsstc.nasa.gov) is one of NASA's twelve Distributed Active Archive Centers responsible for providing access to NASA's Earth science data to users worldwide. Each of NASA's twelve DAACs focuses on a specific science discipline within Earth science, provides data stewardship services and supports its research community's needs. Established in 1991 as the Marshall Space Flight Center DAAC and renamed GHRC in 1997, the data center's original mission focused on the global hydrologic cycle. However, over the years, data holdings, tools and expertise of GHRC have gradually shifted. In 2014, a User Working Group (UWG) was established to review GHRC capabilities and provide recommendations to make GHRC more responsive to the research community's evolving needs. The UWG recommended an update to the GHRC mission, as well as a strategic plan to move in the new direction. After a careful and detailed analysis of GHRC's capabilities, research community needs and the existing data landscape, a new mission statement for GHRC has been crafted: to provide a comprehensive active archive of both data and knowledge augmentation services with a focus on hazardous weather, its governing dynamical and physical processes, and associated applications. Within this broad mandate, GHRC will focus on lightning, tropical cyclones and storm-induced hazards through integrated collections of satellite, airborne, and in-situ data sets. The new mission was adopted at the recent 2015 UWG meeting. GHRC will retain its current name until such time as it has built substantial data holdings aligned with the new mission.

Russo Martin, Elaine

2006-01-01

Objectives: The objective of this study is to apply J. Richard Hackman's framework on team effectiveness to academic medical library settings. Methods: The study uses a qualitative, multiple case study design, employing interviews and focus groups to examine team effectiveness in three academic medical libraries. Another site was selected as a pilot to validate the research design, field procedures, and methods to be used with the cases. In all, three interviews and twelve focus groups, with approximately seventy-five participants, were conducted at the case study libraries. Findings: Hackman identified five conditions leading to team effectiveness and three outcomes dimensions that defined effectiveness. The participants in this study identified additional characteristics of effectiveness that focused on enhanced communication, leadership personality and behavior, and relationship building. The study also revealed an additional outcome dimension related to the evolution of teams. Conclusions: Introducing teams into an organization is not a trivial matter. Hackman's model of effectiveness has implications for designing successful library teams. PMID:16888659

Evaluating a nurse mentor preparation programme.

PubMed

Gray, Olivia; Brown, Donna

Following the introduction of a regional nurse mentor preparation programme, research was undertaken within a health and social care trust to explore both the trainee mentors' and their supervisors' perception of this new programme. A qualitative study involving focus groups was undertaken. The focus groups comprised a total of twelve participants including five trainee mentors and seven supervisors (experienced mentors) who had recently completed a mentor preparation programme. Data were analysed using Braun and Clarke's thematic analysis. Three themes were identified from the data: personal investment (including the emotional impact of mentoring) contextual perceptions (environmental factors such as time) and intellectual facets (related to personal and professional growth). Comprehensive preparation for mentors appears to be effective in developing mentors with the ability to support nursing students in practice. However, further study is required to explore how to support mentors to balance the demands of the mentoring role with the delivery of patient care.

2015-02-17

To determine whether national educational outcomes, course objectives, and classroom assessments for 2 therapeutics courses were aligned for curricular content and cognitive processes, and if they included higher-order thinking. Document analysis and student focus groups were used. Outcomes, objectives, and assessment tasks were matched for specific therapeutics content and cognitive processes. Anderson and Krathwohl's Taxonomy was used to define higher-order thinking. Students discussed whether assessments tested objectives and described their thinking when responding to assessments. There were 7 outcomes, 31 objectives, and 412 assessment tasks. The alignment for content and cognitive processes was not satisfactory. Twelve students participated in the focus groups. Students thought more short-answer questions than multiple choice questions matched the objectives for content and required higher-order thinking. The alignment analysis provided data that could be used to reveal and strengthen the enacted curriculum and improve student learning.

The aim of the study was to explore the patterns of dental health services access in children under twelve years of age in Peru. Data from 25,285 children under 12 years who participated in the Demographic and Family Health Survey of 2014 were reviewed. An exploratory spatial analysis was performed to project the proportions of children with access to dental health services, according to national regions, type of health service and urban or rural place of residence. The results show that of the total sample, 26.7% had access to dental health services in the last six months, 39.6% belonged to the age group 0-4 years, 40.6% lived in the Andean region and 58.3% lived in urban areas. The regions of Huancavelica, Apurimac, Ayacucho, Lima and Pasco had the highest percentages of access nationwide. In conclusion, there is low access to dental health services in the population under 12 years of age in Peru. The spatial distribution of access to dental health services allows regions to be identified and grouped according to similar access patterns, in order to better focus public health actions.

UK national guidance has prioritized developing specialist services for first episode psychosis. Such services are in the early stages of development and a definitive treatment model has yet to be established. The aim of this study was to explore service users' experiences of a first episode intervention designed along evidence-based 'best practice' guidelines and to establish specific elements seen as effective to help inform future service planning and provision. Twelve users of a specialist first episode service participated in focus groups. These were then analyzed using Interpretative Phenomenological Analysis, a specialized form of content analysis. Key elements identified by the service users included the 'human' approach as a key to the recovery process, being involved in treatment decisions, flexibility of appointments, high nurse to patient ratio, reduction in psychotic symptoms, increased confidence and independence and the provision of daily structure. To our knowledge, this is the first systematic qualitative evaluation of users' experience of a specialist first episode treatment intervention. Our findings indicate that adherence to best practice guidelines was appreciated. Regular focus groups provide a continuous audit cycle incorporating service improvements in line with government recommendations, centrally informed by the service users' and caregivers' perspective.

To explore how an opportunistically recruited group of service users with BD experience recovery and self-management to understand more about how a service users' recovery may be supported. Twelve service users with BD took part in a series of focus groups. Service users' responses to questions about their personal experiences of self-management and recovery were analysed. Focus groups were transcribed verbatim and thematic analysis ([ Braun, V., & Clarke, V. (2006). Using thematic analysis in psychology. Qualitative Research in Psychology, 3(2), 77-101]) was employed to identify common themes in the data. Four key themes were identified: (1) Recovery is not about being symptom free; (2) Recovery requires taking responsibility for your own wellness; (3) Self-management: building on existing techniques; (4) Overcoming barriers to recovery: negativity, stigma and taboo. Service users with BD have provided further support for the concept of recovery and have suggested a number of ways recovery can be supported. A self-management approach informed by the recovery literature has been proposed as a way to support service users' recovery.

Emergency communication and information issues in terrorist events involving radioactive materials.

With the threat posed by terrorism involving radioactive materials now high on the nation's agenda, local, state, and federal agencies are moving to enhance preparedness and response capabilities. Crucial to these efforts is the development of effective risk communication strategies. This article reports findings from an ongoing study of risk communication issues in nuclear/radiological terrorism situations. It is part of a larger CDC-funded effort that aims to better understand communication challenges associated with weapons of mass destruction terrorism incidents. Presented here are formative research findings from 16 focus groups (n = 163) in which a multi-part, hypothetical radioactive materials terrorism situation was discussed. Twelve of the focus groups were carried out with members of the general public (drawn from a variety of ethnic backgrounds and geographic locations), and four groups were composed of first responders, hospital emergency department personnel, and public health professionals. One aim of the focus groups was to elicit detailed information on people's knowledge, views, perceptions, reactions, and concerns related to a nuclear/radiological terrorism event, and to better understand people's specific information needs and preferred information sources. A second aim was to pretest draft informational materials prepared by CDC and NIOSH. Key findings for the public and professional groups are presented, and the implications of the research for developing messages in radiological/nuclear terrorism situations are explored.

Altering the Rate of Mitosis by Introducing Low-Gigahertz Radiation to Saccharomyces cerevisiae Cells

This experiment aims to assess the impact of low-frequency radiation (from common technological tools such as cell phones, scanners, and wifi) on the mitotic rates of cells. In particular, the focus of the study was on the growth and development of Saccharomyces cerevisiae cultures that were exposed to radio waves from a wifi router, which were then compared to a cohort of the same species without exposure. Though routers emit a low gigahertz frequency, they are categorized as Group 2B radiation (possibly carcinogenic) by the International Agency for Research on Cancer of the World Health Organization, signifying that constant exposure poses a potential risk to humans. Twelve agar dishes of active Saccharomyces cerevisiae solution were prepared, with six dishes acting as the control under no added radiation and six acting as the experimental group under 2.4 GHz of radiation due to their proximity to the router. Data on how many cultures proliferated in each dish was collected every three days, with the experiment running for a total of twelve days. All subjects experienced growth curves until day 9 when the experimental group's growth peaked with an average of 62 colonies/dish. Three of the six dishes in this group lost colonies in the following three days, leaving the experimental group with an average of 61 colonies/dish on day 12, while the control group was still increasing by day 12 with an average of 48 colonies/dish, with only one dish undergoing a loss of colonies. Exposing the Saccharomyces cerevisiae cells to low grade radiation resulted in accelerated mitosis, and though the experimental group faced colony death after nine days, the loss was likely due to overpopulation in the dish.

Objective Drug craving is defined as an urge to continue substance abuse. Drug dependents use different terms to express their subjective feeling of craving. This study was an attempt to generate an understanding of craving terminology among different groups of Persian speaking Iranian opiate dependents. Method Terms used for the meaning of drug craving were listed by 36 ex-opiate dependents in focus group discussion meetings in the first phase of the study. These terms were composed from Craving Terms Questionnaire. In the second phase, 120 subjects in 3 groups of opiate dependents and a group of Current Opiate Abusers rated usage frequency of each term in the questionnaire under a Twelve-Step Program, Methadone Maintenance, and Other Abstinence-based Programs. Results Eighty nine terms were categorized in stimulation and triggering, attention bias and obsession, decision making difficulty, information processing impairment, withdrawal induction, drug euphoric experience, mental urge, motor control problem, negative valancing and stigmatizing. Terms for the three categories of mental urge, attention bias and obsession and motor control problem were used more than others. Patients in Methadone Maintenance Treatment (MMT) group used different categories of craving terms in comparison to other groups. Abstinent cases reported higher total score for craving terms in comparison to other groups in Twelve-Step Program and other abstinence-based programs. Conclusion Each craving-related term is associated with some aspects of the multidimensional concept of craving. A drug-craving thesaurus could provide a better understanding of craving nature from a drug dependent point of view. There are differences among abstinence vs. maintenance based treated opiate dependents in using craving terms. Addiction therapists will benefit from accessing drug dependents’ lexicon to assess and create therapeutic alliance with their clients. PMID:24130609

To examine discomfort, anxiety, and preferences for decision making in patients undergoing surveillance cystoscopy for non-muscle-invasive bladder cancer (NMIBC). Veterans with a prior diagnosis of NMIBC completed validated survey instruments assessing procedural discomfort, worry, and satisfaction, and were invited to participate in semistructured focus groups about their experience and desire to be involved in surveillance decision making. Focus group transcripts were analyzed qualitatively, using (1) systematic iterative coding, (2) triangulation involving multiple perspectives from urologists and an implementation scientist, and (3) searching and accounting for disconfirming evidence. Twelve patients participated in 3 focus groups. Median number of lifetime cystoscopy procedures was 6.5 (interquartile range 4-10). Based on survey responses, two-thirds of participants (64%) experienced some degree of procedural discomfort or worry, and all participants reported improvement in at least 2 dimensions of overall well-being following cystoscopy. Qualitative analysis of the focus groups indicated that participants experience preprocedural anxiety and worry about their disease. Although many participants did not perceive themselves as having a defined role in decision making surrounding their surveillance care, their preferences to be involved in decision making varied widely, ranging from acceptance of the physician's recommendation, to uncertainty, to dissatisfaction with not being involved more in determining the intensity of surveillance care. Many patients with NMIBC experience discomfort, anxiety, and worry related to disease progression and not only cystoscopy. Although some patients are content to defer surveillance decisions to their physicians, others prefer to be more involved. Future work should focus on defining patient-centered approaches to surveillance decision making. Published by Elsevier Inc.

Objectives To explore women’s knowledge, attitudes, and beliefs about adverse outcomes associated with smoking during pregnancy and which outcomes might motivate cessation; to explore reactions to graphic warnings depicting 2 adverse outcomes. Methods Twelve focus groups were conducted with women of childbearing age who were current smokers. Results Participants had low to moderate awareness of many outcomes and believed it was acceptable to smoke in the first trimester before knowledge of pregnancy. Perceived susceptibility to outcomes was low. Motivators included risk-focused information, especially serious risks to the baby (eg, stillbirth, SIDS). Graphic warnings produced strong reactions, especially the warning with a real photo. Conclusions Despite barriers to reducing rates of smoking during pregnancy, educational information and photos depicting babies’ risks could motivate women to quit. PMID:24933145

The twelve-step recovery model of AA: a voluntary mutual help association.

PubMed

Borkman, Thomasina

2008-01-01

Alcoholism treatment has evolved to mean professionalized, scientifically based rehabilitation. Alcoholics Anonymous (AA) is not a treatment method; it is far better understood as a Twelve-Step Recovery Program within a voluntary self-help/mutual aid organization of self-defined alcoholics. The Twelve-Step Recovery Model is elaborated in three sections, patterned on the AA logo (a triangle within a circle): The triangle's legs represent recovery, service, and unity; the circle represents the reinforcing effect of the three legs upon each other as well as the "technology" of the sharing circle and the fellowship. The first leg of the triangle, recovery, refers to the journey of individuals to abstinence and a new "way of living." The second leg, service, refers to helping other alcoholics which also connects the participants into a fellowship. The third leg, unity, refers to the fellowship of recovering alcoholics, their groups, and organizations. The distinctive AA organizational structure of an inverted pyramid is one in which the members in autonomous local groups direct input to the national service bodies creating a democratic, egalitarian organization maximizing recovery. Analysts describe the AA recovery program as complex, implicitly grounded in sound psychological principles, and more sophisticated than is typically understood. AA provides a nonmedicalized and anonymous "way of living" in the community and should probably be referred to as the Twelve-Step/Twelve Tradition Recovery Model in order to clearly differentiate it from professionally based twelve-step treatments. There are additional self-help/mutual aid groups for alcoholics who prefer philosophies other than AA.

We conducted a qualitative study to explore parental beliefs about emotions in the family across three cultures (African American, European American, and Lumbee American Indian), using the underutilized yet powerful methodology of focus groups. The main goal of this monograph is to understand parents’ beliefs about the role of emotions in the family and how cultural or ethnic background may influence those beliefs. Based on philosophical traditions and previous research, three dimensions of parental beliefs were predicted: Value of Emotion, Socialization of Emotion, and Controllability of Emotion. We expected new themes to emerge during the focus groups.Twelve focus groups were conducted with 87 parents from the three cultural groups mentioned above. Groups met for two sessions scheduled 2 weeks apart. Focus group discussions were led by same-ethnicity moderators. Aninductive analysis was conducted; key themes and subthemes were identified.All three theoretically derived dimensions were well represented in each focus group. Cultural similarities in themes within these dimensions included children’s appropriate expression of negative emotions, role of emotion in the home, children’s capacity for controlling emotions, and parents’ role in socialization of emotion. Cultural variations included concern about parents’ expression of negative emotion, children’s modulation of positive emotion, the role emotions play in behavior, and choice in emotional experience. Two new dimensions also emerged: Relational Nature of Emotions and Changeability of Emotions. Cultural similarities in themes within these dimensions included emphasis on emotional connections with children, emotional contagion in families, developmental change in children’s emotions, and intergenerational change in emotion socialization. Cultural variation included discussion of emotions as guides for action and children’s emotional privacy. Dimensions and the themes and subthemes within them are presented with supporting evidence and sources. Implications of parental beliefs for emotion socialization theory and future research, as well as limitations, are discussed.

Physicians can play a significant role in helping to decrease the hepatitis B virus (HBV) burden among Asian Americans. Few studies have described knowledge and practice patterns in the medical community among different provider types regarding HBV and liver cancer. Our study explores the HBV beliefs, attitudes and practice patterns of medical providers serving Asian American communities. We conducted three focus groups with primary care providers, liver specialists, and other providers predominantly serving Asian American community. We asked about practices and barriers to appropriate medical care and outreach. We moderated three focus groups with 23 participants, 18 of whom completed and returned demographic surveys. Twelve were of Asian ethnicity and 13 spoke English as a second language. Only eight screened at least half of their patients, most (72%) using the hepatitis B surface antigen test. We used grounded theory methods to analyze focus group transcripts. Participants frequently discussed cultural and financial barriers to hepatitis care. They admitted reluctance to screen for HBV because patients might be unwilling or unable to afford treatment. Cultural differences were discussed most by primary care providers; best methods of outreach were discussed most by liver specialists; and alternative medicine was discussed most by acupuncturists and other providers. More resources are needed to lower financial barriers complicating HBV care and encourage providing guideline-recommended screenings. Other providers can help promote HBV screening and increase community and cultural awareness.

Transforming user needs into functional requirements for an antibiotic clinical decision support system: explicating content analysis for system design.

Many informatics studies use content analysis to generate functional requirements for system development. Explication of this translational process from qualitative data to functional requirements can strengthen the understanding and scientific rigor when applying content analysis in informatics studies. To describe a user-centered approach transforming emergent themes derived from focus group data into functional requirements for informatics solutions and to illustrate these methods to the development of an antibiotic clinical decision support system (CDS). THE APPROACH CONSISTED OF FIVE STEPS: 1) identify unmet therapeutic planning information needs via Focus Group Study-I, 2) develop a coding framework of therapeutic planning themes to refine the domain scope to antibiotic therapeutic planning, 3) identify functional requirements of an antibiotic CDS system via Focus Group Study-II, 4) discover informatics solutions and functional requirements from coded data, and 5) determine the types of information needed to support the antibiotic CDS system and link with the identified informatics solutions and functional requirements. The coding framework for Focus Group Study-I revealed unmet therapeutic planning needs. Twelve subthemes emerged and were clustered into four themes; analysis indicated a need for an antibiotic CDS intervention. Focus Group Study-II included five types of information needs. Comments from the Barrier/Challenge to information access and Function/Feature themes produced three informatics solutions and 13 functional requirements of an antibiotic CDS system. Comments from the Patient, Institution, and Domain themes generated required data elements for each informatics solution. This study presents one example explicating content analysis of focus group data and the analysis process to functional requirements from narrative data. Illustration of this 5-step method was used to develop an antibiotic CDS system, resolving unmet antibiotic prescribing needs. As a reusable approach, these techniques can be refined and applied to resolve unmet information needs with informatics interventions in additional domains.

Obesity prevention is an international public health priority. The prevalence of obesity and overweight is increasing in child populations throughout the world, impacting on short and long-term health. Obesity prevention strategies for children can change behaviour but efficacy in terms of preventing obesity remains poorly understood. To assess the effectiveness of interventions designed to prevent obesity in childhood through diet, physical activity and/or lifestyle and social support. MEDLINE, PsycINFO, EMBASE, CINAHL and CENTRAL were searched from 1990 to February 2005. Non-English language papers were included and experts contacted. Randomised controlled trials and controlled clinical trials with minimum duration twelve weeks. Two reviewers independently extracted data and assessed study quality. Twenty-two studies were included; ten long-term (at least 12 months) and twelve short-term (12 weeks to 12 months). Nineteen were school/preschool-based interventions, one was a community-based intervention targeting low-income families, and two were family-based interventions targeting non-obese children of obese or overweight parents. Six of the ten long-term studies combined dietary education and physical activity interventions; five resulted in no difference in overweight status between groups and one resulted in improvements for girls receiving the intervention, but not boys. Two studies focused on physical activity alone. Of these, a multi-media approach appeared to be effective in preventing obesity. Two studies focused on nutrition education alone, but neither were effective in preventing obesity. Four of the twelve short-term studies focused on interventions to increase physical activity levels, and two of these studies resulted in minor reductions in overweight status in favour of the intervention. The other eight studies combined advice on diet and physical activity, but none had a significant impact. The studies were heterogeneous in terms of study design, quality, target population, theoretical underpinning, and outcome measures, making it impossible to combine study findings using statistical methods. There was an absence of cost-effectiveness data. The majority of studies were short-term. Studies that focused on combining dietary and physical activity approaches did not significantly improve BMI, but some studies that focused on dietary or physical activity approaches showed a small but positive impact on BMI status. Nearly all studies included resulted in some improvement in diet or physical activity. Appropriateness of development, design, duration and intensity of interventions to prevent obesity in childhood needs to be reconsidered alongside comprehensive reporting of the intervention scope and process.

To explicate lay theories relating to social isolation and to identify instances of positive deviance to inform future efforts to encourage older people to participate in protective behaviors. Twelve focus groups and 20 individual interviews were conducted with Australians aged 40 years and older. Data were collected in metropolitan and regional areas. The age threshold was based on the need to generate formative research to inform interventions to encourage people to engage in preventive behaviors prior to reaching older age when they become more susceptible to social isolation. Two primary lay theories were identified in the data. These are related to the recognized importance of social connection and the belief that forming new social connections becomes more difficult with age due to a range of individual and external factors. Examples of positive deviance that were identified included viewing overcoming social isolation as an incremental process, being prepared to be the instigator of social interaction, and adopting an external focus. The findings suggest that the provision of a broad range of group activities may need to be combined with a focused approach to targeting and approaching those most at risk to reduce the burden of social isolation at a population level.

Daughter-initiated health advice to mothers: perceptions of African–American and Latina daughters

PubMed Central

Mosavel, M.; Thomas, T.

2009-01-01

The prevailing paradigm of health exchange within the family is for health advice to flow from parent to child. Consistent with this pattern of exchange, most research has focused on the one-directional influence of the parent on the child and there is thus an absence of literature that explores the ability of adolescents to influence their parents’ health behaviors. This qualitative study addressed this gap by exploring the feasibility of daughters providing health advice to their mothers. Twelve focus groups were conducted with 78 African–American and Latina daughters between the ages of 12 and 17 from low-income neighborhoods in a Mid-Western city in the United States. This study utilized a grounded theory approach to examine the focus group data. The findings indicate that many daughters report that they are already giving their mothers a wide spectrum of advice, including health advice. Differences were found in the reported willingness of African–American daughters when compared to Latina daughters to provide their mothers with specific cancer advice. These data suggest that some of these daughters have the potential to be valuable health education conveyers in the family. PMID:19339373

Synthetic schemes were developed and optimized for twelve new monomers possessing unique structural features and one aspartimide. Two synthetic pathways were compared for preparation of the triarylethane monomers with pendent ethynyl groups. The results show that one of these pathways can be generally applied. The alternative pathway was applicable to the preparation of only one of the twelve compounds, the problem being secondary reactions of the initially formed desired product.

Reducing HIV sexual risk among African American women who use drugs: hearing their voices.

A pilot study was conducted to understand women's realities, perspectives, and perceived needs regarding the interaction between substance use, types of sexual relationships, and the challenges and barriers they pose to practicing safer sex. An additional purpose was to examine this population's willingness to participate in the program and receptiveness to the components of proposed interventions. Data were collected in this descriptive, exploratory study by the use of one focus group. Twelve African American women between 20 and 55 years of age who had previous drug detoxification experience participated in a 3-hour focus group. All participants were sexually active as well as current users of illicit substances, and all but one had traded sex for money, drugs, or alcohol. The focus group interview was guided by a semistructured questionnaire. Participants were recruited by counselors in detoxification units. Each unit counselor was asked to randomly select a third of their residents, explain and read the purpose of the focus group, and get the residents' verbal consent to participate. The women discussed their sexual behaviors and drug use that increased their risk for acquiring HIV. They provided insight about the effects of different drugs on one's sexual behavior, motivation for sex, and reasons for unsafe sex and made recommendations for HIV prevention intervention. Participants agreed that safer sex and healthy living intervention would be most beneficial if placed within the context of a detoxification program. The juxtaposition of increased sexual risk behavior and the potential to acquire and transmit HIV infection suggests the urgency of intervening with African American women who are substance abusers.

Although there are numerous studies that show that emergency department (ED) violence is a prevalent and serious problem for healthcare workers, there is a lack of published evaluations of interventions aimed at reducing this alarming trend. Using an action research model, the authors partnered with six hospitals to plan, implement and evaluate a violence prevention and management intervention. Phase one of this project involved gathering information from employees, managers and patients using focus groups. Ninety-seven persons participated in one of twelve focus groups. The Haddon matrix was used to develop focus group questions aimed at gathering data about the pre-assault, during assault, and post-assault time frames and to compare these findings to planned strategies. Analysis consisted of identification of themes related to intervention strategies for patients/visitors, employees, managers, and the work environment. Thematic analysis results supported the relevance, feasibility, and saliency of the planned intervention strategies. With the exception of a few items, employees and managers from the different occupational groups agreed on the interventions needed to prevent and manage violence against ED workers. Patients focused on improved staff communication and comfort measures. Results support that violence in the emergency department is increasing, that violence is a major concern for those who work in and visit emergency departments, and that interventions are needed to reduce workplace violence. The Haddon matrix along with an action research method was useful to identify intervention strategies most likely to be successfully implemented and sustained by the emergency departments.

Objective To examine a prevailing conceptual model of health services use (Andersen 1995) and to suggest modifications that may enhance its explanatory power when applied to empirical studies of race/ethnicity and long-term care. Study Setting Twelve focus groups of African-American (five groups) and white (seven groups) individuals, aged 65 and older, residing in Connecticut during 2000. Study Design Using qualitative analysis, data were coded and analyzed in NUD-IST 4 software to facilitate the reporting of recurrent themes, supporting quotations, and links among the themes for developing the conceptual framework. Specific analysis was conducted to assess distinctions in common themes between African-American and white focus groups. Data Collection Data were collected using a standardized discussion guide, augmented by prompts for clarification. Audio taped sessions were transcribed and independently coded by investigators and crosschecked to enhance coding validity. An audit trail was maintained to document analytic decisions during data analysis and interpretation. Principal Findings Psychosocial factors (e.g., attitudes and knowledge, social norms, and perceived control) are identified as determinants of service use, thereby expanding the Andersen model (1995). African-American and white focus group members differed in their reported accessibility of information about long-term care, social norms concerning caregiving expectations and burden, and concerns of privacy and self-determination. Conclusions More comprehensive identification of psychosocial factors may enhance our understanding of the complex role of race/ethnicity in long-term care use as well as the effectiveness of policies and programs designed to address disparities in long-term care service use among minority and nonminority groups.

Qualitative findings from focus group discussions on hand hygiene compliance among health care workers in Vietnam.

PubMed

Salmon, Sharon; McLaws, Mary-Louise

2015-10-01

It is accepted by hospital clinical governance that every clinician's "duty of care" includes hand hygiene, yet globally, health care workers (HCWs) continue to struggle with compliance. Focus group discussions were conducted to explore HCWs' barriers to hand hygiene in Vietnam. Twelve focus group discussions were conducted with HCWs from 6 public hospitals across Hanoi, Vietnam. Discussions included participants' experiences with and perceptions concerning hand hygiene. Tape recordings were transcribed verbatim and then translated into English. Thematic analysis was conducted by 2 investigators. Expressed frustration with high workload, limited access to hand hygiene solutions, and complicated guidelines that are difficult to interpret in overcrowded settings were considered by participants to be bona fide reasons for noncompliance. No participant acknowledged hand hygiene as a duty of care practice for her or his patients. Justification for noncompliance was the observation that visitors did not perform hand hygiene. HCWs did acknowledge a personal duty of care when hand hygiene was perceived to benefit her or his own health, and then neither workload or environmental challenges influenced compliance. Limited resources in Vietnam are amplified by overcrowded conditions and dual bed occupancy. Yet without a systematic systemic duty of care to patient safety, changes to guidelines and resources might not immediately improve compliance. Thus, introducing routine hand hygiene must start with education programs focusing on duty of care. Copyright © 2015 Association for Professionals in Infection Control and Epidemiology, Inc.

Nineteen focus groups and nine interviews were conducted. Audio files were transcribed and organized into NVivo10. Recurring themes were examined by geographic location. Although similar barriers, motivators, and strategies were reported by urban and rural groups, perceptions regarding their importance varied. Recruitment barriers mentioned in both rural and urban groups included fear, side effects, limited understanding, limited time, and mistrust. Rural groups were more mindful of time commitment involved. Both rural and urban participants reported financial incentives as the top motivator to CT participation, followed by personal illness (urban groups) and benefits to family (rural groups). Recruitment strategies suggested by rural participants involved working with schools/churches and using word of mouth, whereas partnering with schools, word of mouth, and media were recommended most by urban groups. Perceived recruitment barriers, motivators, and strategies did not differ considerably between rural and urban groups. Major barriers identified by participants should be addressed in future CT recruitment and education efforts. Findings can inform recruitment and communication strategies for reaching both urban and rural communities.

Physical and cognitive training seem to counteract age-related decline in physical and mental function. Recently, the possibility of integrating cognitive demands into physical training has attracted attention. The purpose of this study was to evaluate the effects of twelve weeks of designed physical-cognitive training on executive cognitive function and gait performance in older adults. Thirty-six healthy, active individuals aged 72.30 ± 5.84 years were assigned to two types of physical training with major focus on physical single task (ST) training (n = 16) and physical-cognitive dual task (DT) training (n = 20), respectively. They were tested before and after the intervention for executive function (inhibition, working memory) through Random Number Generation and for gait (walking with/without negotiating hurdles) under both single and dual task (ST, DT) conditions. Gait performance improved in both groups, while inhibitory performance decreased after exercise training with ST focus but tended to increase after training with physical-cognitive DT focus. Changes in inhibition performance were correlated with changes in DT walking performance with group differences as a function of motor task complexity (with/without hurdling). The study supports the effectiveness of group exercise classes for older individuals to improve gait performance, with physical-cognitive DT training selectively counteracting the age-related decline in a core executive function essential for daily living.

This study is the 3rd piece of formative research utilizing the theory of planned behavior to inform the development of a behavior change intervention. Focus groups were used to identify reasons for and solutions to previously identified key beliefs in addition to potentially effective behavior change techniques. A purposive sample of 22 first-year undergraduate students (n = 8 men; M age  = 19.8 years, SD = 1.3 years) attending a university in the North of England was used. Focus groups were audio-recorded; recordings were transcribed verbatim, analyzed thematically, and coded for recurrent themes. The data revealed 14 reasons regarding enjoyment, 11 reasons for friends' approval, 11 reasons for friends' own participation, 14 reasons for the approval of family members, and 10 solutions to time constraints. Twelve distinct techniques were suggested to attend to these reasons and solutions. This qualitative research will be used to inform the development of a theory-based intervention to increase students' participation in university recreational sports.

The use of extracorporeal shock wave therapy for the treatment of lateral epicondylitis is controversial. The purpose of this study was to evaluate the use of extracorporeal shock wave therapy without local anesthesia to treat chronic lateral epicondylitis. One hundred and fourteen patients with a minimum six-month history of lateral epicondylitis that was unresponsive to conventional therapy were randomized into double-blind active treatment and placebo groups. The protocol consisted of three weekly treatments of either low-dose shock wave therapy without anesthetic or a sham treatment. Patients had a physical examination, including provocation testing and dynamometry, at one, four, eight, and twelve weeks and at six and twelve months after treatment. Radiographs, laboratory studies, and electrocardiograms were also evaluated prior to participation and at twelve weeks. A visual analog scale was used to evaluate pain, and an upper extremity functional scale was used to assess function. Crossover to active treatment was initiated for nonresponsive patients who had received the placebo and met the inclusion criteria after twelve weeks. A total of 108 of the 114 randomized patients completed all treatments and the twelve weeks of follow-up required by the protocol. Sixty-one patients completed one year of follow-up, whereas thirty-four patients crossed over to receive active treatment. A significant difference (p = 0.001) in pain reduction was observed at twelve weeks in the intent-to-treat cohort, with an improvement in the pain score of at least 50% seen in 61% (thirty-four) of the fifty-six patients in the active treatment group who were treated according to protocol compared with 29% (seventeen) of the fifty-eight subjects in the placebo group. This improvement persisted in those followed to one year. Functional activity scores, activity-specific evaluation, and the overall impression of the disease state all showed significant improvement as well (p < 0.05). Crossover patients also showed significant improvement after twelve weeks of active treatment, with 56% (nineteen of thirty-four) achieving an improvement in the pain score of at least 50% (p < 0.0001). These results demonstrate that low-dose shock wave therapy without anesthetic is a safe and effective treatment for chronic lateral epicondylitis.

Abstract The success of home telemedicine depends on end-user adoption, which has been slow despite rapid advances in technological development. This study focuses on an examination of significant factors that may predict the successful adoption of home telemedicine services (HTS) among older adults. Based on previous studies in the fields of remote patient monitoring, assisted living technologies, and consumer health information technology acceptance, eight factors were identified as a framework for qualitative testing. Twelve focus groups were conducted with an older population living in both urban and rural environments. The results reveal seven predictors that play an important role in perceptions of HTS: perceived usefulness, effort expectancy, social influence, perceived security, computer anxiety, facilitating conditions, and physicians' opinion. The results provide important insights in the field of older adults' acceptance of HTS, with guidelines for the strategic planning, developing, and marketing of HTS for the graying market.

The HIV epidemic presents challenges including orphans and a large mass of children rendered vulnerable by the epidemic and other societal forces. Focus on orphaned and vulnerable children (OVC) is important, but needs accurate definition. Twelve focus group interviews of service providers, leaders in these communities, OVC and their caretakers were conducted at six project sites across Botswana, South Africa and Zimbabwe to extend this definition. The loss of a parent through death or desertion is an important aspect of vulnerability. Additional factors leading to vulnerability included severe chronic illness of a parent or caregiver, poverty, hunger, lack of access to services, inadequate clothing or shelter, overcrowding, deficient caretakers, and factors specific to the child, including disability, direct experience of physical or sexual violence, or severe chronic illness. Important questions raised in this research include the long-term implications for the child and community, and the contribution of culture systems.

A large-scale examination of the effectiveness of anonymous marking in reducing group performance differences in higher education assessment.

Hinton, Daniel P; Higson, Helen

2017-01-01

The present research aims to more fully explore the issues of performance differences in higher education assessment, particularly in the context of a common measure taken to address them. The rationale for the study is that, while performance differences in written examinations are relatively well researched, few studies have examined the efficacy of anonymous marking in reducing these performance differences, particularly in modern student populations. By examining a large archive (N = 30674) of assessment data spanning a twelve-year period, the relationship between assessment marks and factors such as ethnic group, gender and socio-environmental background was investigated. In particular, analysis focused on the impact that the implementation of anonymous marking for assessment of written examinations and coursework has had on the magnitude of mean score differences between demographic groups of students. While group differences were found to be pervasive in higher education assessment, these differences were observed to be relatively small in practical terms. Further, it appears that the introduction of anonymous marking has had a negligible effect in reducing them. The implications of these results are discussed, focusing on two issues, firstly a defence of examinations as a fair and legitimate form of assessment in Higher Education, and, secondly, a call for the re-examination of the efficacy of anonymous marking in reducing group performance differences.

We aimed to evaluate the effectiveness of an 8-week meditation program (focused meditation) in patients with chronic low-back pain. A randomized clinical trial was conducted on 68 patients (55 years;75% female) with chronic low-back pain who scored >40mm on a 100mm Visual-Analogue-Scale. Subjects were allocated to an 8-week meditation program (focused meditation) with weekly 75min classes or to a self-care exercise program with a wait-list offer for meditation. Both groups were instructed to practice at home. Outcomes were assessed baseline and after 4 and 8 weeks. The primary outcome measure was the change in mean back pain at rest after 8 weeks. Secondary outcomes included function, pain-related bothersomeness, perceived stress, quality-of-life (QOL), and psychological outcomes. Twelve (meditation) and 4 (exercise) patients were lost to follow-up. The primary outcome, pain at rest after 8 weeks, was reduced from 59.3±13.9mm to 40.8±21.8mm with meditation vs. 52.9±11.8mm to 37.3±18.2mm with exercise (adjusted group difference: -1.4 (95%CI:11.6;8.8;p=n.s.) Perceived stress was significantly more reduced with meditation (p=0.011). No significant treatment effects were found for other secondary outcomes as pain-related bothersomeness, function, quality-of-life and psychological scores, although the meditation group consistently showed non-significant better improvements compared to the exercise group. Focused meditation and self-care exercise lead to comparable, symptomatic improvements in patients with chronic low back pain. Future studies should include longer-term follow-ups and develop guided meditation programs to support compliance. Copyright © 2016 Elsevier Ltd. All rights reserved.

Men who have sex with men (MSM) continue to be disproportionately affected by HIV and sexually transmitted diseases. This study was designed to explore sexual risk among MSM using community-based participatory research (CBPR). An academic-community partnership conducted nine focus groups with 88 MSM. Participants self-identified as African American/Black (n=28), Hispanic/Latino (n=33), White (n=21), and biracial/ethnic (n=6). The mean age was 27 years (range=18-60 years). Grounded theory was used. Twelve themes related to HIV risk emerged, including low knowledge of HIV and sexually transmitted diseases, particularly among Latino MSM and MSM who use the Internet for sexual networking; stereotyping of African American MSM as sexually "dominant" and Latino MSM as less likely to be HIV infected; and the eroticization of "barebacking." Twelve intervention approaches also were identified, including developing culturally congruent programming using community-identified assets, harnessing social media used by informal networks of MSM, and promoting protection within the context of intimate relationships. A community forum was held to develop recommendations and move these themes to action. © The Author(s) 2011

The objective of this study was to describe the oral phase of swallowing in individuals with dental malocclusion and to generate data that would contribute to the rehabilitation of those patients. The study was based on the evaluation of the swallowing system through videofluoroscopy on thirty-four children of both genders, aged eight to twelve years old who present with Angle Class II and III dental malocclusions. Thirteen children of similar age and gender presenting normal dental occlusion formed the control group. The results indicated that the oral phase of swallowing is different between individuals with normal occlusion and malocclusion. Dental occlusion types Angle Class II and III did not present a swallowing pattern, independently of the amount of liquid ingested. The swallowing appeared effective in the oral phase of individuals with dental malocclusion, even though adaptations were identified. The outcome, in the absence of a single pattern and the efficiency of the adapted swallowing demonstrates, first a need for additional research investigating orofacial myofunctional treatment for patients with malocclusion and second how such analyses should focus on contributing positively to the rehabilitation of these patients.

Findings of a study of the impact of professional learning on Malaysian registered nurses are reported. The offshore delivery post-registration nursing degree programme is a formal aspect of professional learning, which enables Malaysian registered nurses to upgrade their hospital-based training or diploma of nursing qualification to a degree. Using a qualitative case study approach, data were collected from twelve programme graduates, through individual and focus group interviews. The programme promoted their personal professional growth and enhanced their professional development. It increased self-confidence, knowledge, self-fulfillment, critical thinking ability, interpersonal skills, interest in research and research utilisation, and life-long learning. There was evidence of career mobility and a raised awareness of their professional role and responsibility.

There is a variety of treatment modalities for unicameral bone cysts, with variable outcomes reported in the literature. Although good initial outcomes have been reported, the success rate has often changed with longer-term follow-up. We introduce a novel, minimally invasive treatment method and compare its clinical outcomes with those of other methods of treatment of this lesion. From February 1994 to April 2008, forty patients with a unicameral bone cyst were treated with one of four techniques: serial percutaneous steroid and autogenous bone-marrow injection (Group 1, nine patients); open curettage and grafting with a calcium sulfate bone substitute either without instrumentation (Group 2, twelve patients) or with internal instrumentation (Group 3, seven patients); or minimally invasive curettage, ethanol cauterization, disruption of the cystic boundary, insertion of a synthetic calcium sulfate bone-graft substitute, and placement of a cannulated screw to provide drainage (Group 4, twelve patients). Success was defined as radiographic evidence of a healed cyst or of a healed cyst with some defect according to the modified Neer classification, and failure was defined as a persistent or recurrent cyst that needed additional treatment. Patients who sustained a fracture during treatment were also considered to have had a failure. The outcome parameters included the radiographically determined healing rate, the time to solid union, and the total number of procedures needed. The follow-up time ranged from eighteen to eighty-four months. Group-4 patients had the highest radiographically determined healing rate. Healing was seen in eleven of the twelve patients in that group compared with three of the nine in Group 1, eight of the twelve in Group 2, and six of the seven in Group 3. Group-4 patients also had the shortest mean time to union: 3.7 ± 2.3 months compared with 23.4 ± 14.9, 12.2 ± 8.5, and 6.6 ± 4.3 months in Groups 1, 2, and 3, respectively. This new minimally invasive method achieved a favorable outcome, with a higher radiographically determined healing rate and a shorter time to union. Thus, it can be considered an option for initial treatment of unicameral bone cysts.

Rates of participation in regular exercise are lower among individuals with arthritis than those without arthritis. This study examined perceived exercise barriers, benefits, and enablers in exercising and nonexercising adults with arthritis. Twelve focus groups were conducted with 68 adults with arthritis. Groups were segmented by exercise status, socioeconomic status, and race. Focus group discussions were transcribed verbatim and coded. NVivo software was used to extract themes for exercisers and nonexercisers. A wide range of physical, psychological, social, and environmental factors were perceived to influence exercise. Some of these factors were similar to those in general adult samples, whereas others were unique to individuals with chronic disease. Symptoms of arthritis were barriers to exercise, yet improvements in these outcomes were also seen as potential benefits of and motivations for exercise. Exercisers had experienced these benefits and were more likely to have adapted their exercise to accommodate the disease, whereas nonexercisers desired these benefits and were more likely to have stopped exercising since developing arthritis. Health care providers' advice to exercise and the availability of arthritis-specific programs were identified as needs. This study has implications for how to market exercise to individuals with arthritis and how communities and health care professionals can facilitate the uptake of exercise. These implications are discussed.

Risk sexual practice among students from public universities/colleges is common in Ethiopia. However, little has been known about risk sexual behavior of students in private colleges where more students are potentially enrolled. Therefore, this study aimed to assess the magnitude of risky sexual behaviors and predictors among students of Private Colleges in Mekelle City. A mixed design of both quantitative and qualitative methods was used among 627 randomly selected students of private colleges from February to march 2013. Self administered questionnaire and focus group discussion was used to collect data. A thematic content analysis was used for the qualitative part. For the quantitative study, Univariate, Bivariate and multivariable analysis was made using SPSS version 16 statistical package and p value less than 0.05 was used as cut off point for a statistical significance. Among the total 590 respondents, 151 (29.1%) have ever had sex. Among the sexually active students, 30.5% reported having had multiple sexual partners and consistent condom use was nearly 39%. In multivariable logistic regression analysis, variables such as sex, age group, sex last twelve months and condom use last twelve months was found significantly associated with risky sexual behavior. The findings of qualitative and quantitative study showed consistency in presence of risk factors. Finding of this study showed sexual risk behaviors is high among private colleges such as multiple sexual partners and substance use. So that colleges should emphasis on promoting healthy sexual and reproductive health programs.

Achieving participant comprehension has proven to be one of the most difficult, practical, and ethical challenges of HIV prevention clinical trials. It becomes even more challenging when local languages do not have equivalent scientific and technical vocabularies, rendering communication of scientific concepts in translated documents extremely difficult. Even when bilingual lexicons are developed, there is no guarantee that participants understand the terminology as translated. We conducted twelve focus groups with women of reproductive age in Mwanza, Tanzania to explore the effectiveness of four questioning techniques for: (1) assessing participants' familiarity with existing technical terms and concepts, (2) generating a list of acceptable technical and non-technical terms, (3) testing our definitions of technical terms, and (4) verifying participants' preferences for terms. Focus groups were transcribed, translated, and qualitatively analyzed. A translation process that uses all four questioning techniques in a step-wise approach is an effective way to establish a baseline understanding of participants' familiarity with research terms, to develop and test translatable definitions, and to identify participants' preferred terminology for international HIV clinical research. This may help to ensure that important concepts are not "lost in translation." The results emphasize the importance of using a variety of techniques depending on the level of participant familiarity with research concepts, the existence of colloquial or technical terms in the target language, and the inherent complexity of the terms.

This study examines whether horses can learn by observing humans, given that they identify individual humans and orientate on the focus of human attention. We tested 24 horses aged between 3 and 12. Twelve horses were tested on whether they would learn to open a feeding apparatus by observing a familiar person. The other 12 were controls and received exactly the same experimental procedure, but without a demonstration of how to operate the apparatus. More horses from the group with demonstration (8/12) reached the learning criterion of opening the feeder twenty times consecutively than horses from the control group (2/12), and younger horses seemed to reach the criterion more quickly. Horses not reaching the learning criteria approached the human experimenters more often than those that did. The results demonstrate that horses learn socially across species, in this case from humans.

Using guidance from the reach, efficacy, adoption, implementation, and maintenance evaluation framework, we aimed to qualitatively evaluate the participant experiences of a workplace high-intensity interval training (HIIT) intervention. Twelve previously insufficiently active individuals (four males and eight females) were interviewed once as part of three focus groups. Perceptions of program satisfaction, barriers to and facilitators of adherence, and persistence to exercise were explored. HIIT initiates interest because of its novelty, provides a sense of accomplishment, and overcomes the barriers of perceived lack of time. The feeling of relatedness between the participants can attenuate negative unpleasant responses during the HIIT sessions. HIIT, in this workplace setting, is an acceptable intervention for physically inactive adults. However, participants were reluctant to maintain the same mode of exercise, believing that HIIT sessions were for the very fit.

Mental states and activities in Danish narratives: children with autism and children with language impairment.

This study focuses on the relationship between content elements and mental-state language in narratives from twenty-seven children with autism (ASD), twelve children with language impairment (LI), and thirty typically developing children (TD). The groups did not differ on chronological age (10;6-14;0) and non-verbal cognitive skills, and the groups with ASD and TD did not differ on language measures. The children with ASD and LI had fewer content elements of the storyline than the TD children. Compared with the TD children, the children with ASD used fewer subordinate clauses about the characters' thoughts, and preferred talking about mental states as reported speech, especially in the form of direct speech. The children with LI did not differ from the TD children on these measures. The results are discussed in the context of difficulties with socio-cognition in children with ASD and of language difficulties in children with LI.

Biodegradable implants for internal fixation of ankle fractures may overcome some disadvantages of metallic implants, such as imaging interference and the potential need for additional surgery to remove the implants. The purpose of this study was to evaluate the outcomes after fixation of ankle fractures with biodegradable implants compared with metallic implants. In this prospectively randomized study, 109 subjects with an ankle fracture underwent surgery with metallic (Group I) or biodegradable implants (Group II). Radiographic results were assessed by the criteria of the Klossner classification system and time to bone union. Clinical results were assessed with use of the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scale, Short Musculoskeletal Function Assessment (SMFA) dysfunction index, and the SMFA bother index at three, six, and twelve months after surgery. One hundred and two subjects completed the study. At a mean of 19.7 months, there were no differences in reduction quality between the groups. The mean operative time was 30.2 minutes in Group I and 56.4 minutes in Group II (p < 0.001). The mean time to bone union was 15.8 weeks in Group I and 17.6 weeks in Group II (p = 0.002). The mean AOFAS score was 87.5 points in Group I and 84.3 points in Group II at twelve months after surgery (p = 0.004). The mean SMFA dysfunction index was 8.7 points in Group I and 10.5 points in Group II at twelve months after surgery (p = 0.060). The mean SMFA bother index averaged 3.3 points in Group I and 4.6 points in Group II at twelve months after surgery (p = 0.052). No difference existed between the groups with regard to clinical outcomes for the subjects with an isolated lateral malleolar fracture. The outcomes after fixation of bimalleolar ankle fractures with biodegradable implants were inferior to those after fixation with metallic implants in terms of the score on the AOFAS scale and time to bone union. However, the difference in the final AOFAS score between the groups may not be clinically important. The outcomes associated with the use of biodegradable implants for the fixation of isolated lateral malleolar fractures were comparable with those for metallic implants.

Most U.S. healthcare professionals encourage mutual-help group involvement as an adjunct to treatment or aftercare for individuals with substance use disorders, yet there are multiple challenges in engaging in these community groups. Dually diagnosed individuals (DDIs) may face additional challenges in affiliating with mutual-help groups. Twelve-step facilitation for DDIs (TSF-DD), a manualized treatment to facilitate mutual-help group involvement, was developed to help patients engage in Double Trouble in Recovery (DTR), a mutual-help group tailored to DDIs. Given the promising role that TSF-DD and DTR may have for increasing abstinence while managing psychiatric symptoms, the aim of the current study was to systematically examine reasons for TSF-DD and DTR attendance from the perspective of DDIs using focus group data. Participants were a subset (n = 15) of individuals diagnosed with an alcohol use disorder as well as a major depressive, bipolar, or psychotic disorder who participated in a parent study testing the efficacy of TSF-DD for increasing mutual-help group involvement and reducing alcohol use. Analyses of focus group data revealed that participants construed DTR and TSF-DD as helpful tools in the understanding and management of their disorders. Relative to other mutual-help groups in which participants reported feeling ostracized because of their dual diagnoses, participants reported that it was beneficial to learn about dual disorders in a safe and accepting environment. Participants also expressed aspects that they disliked. Results from this study yield helpful empirical recommendations to healthcare professionals seeking to increase DDIs' participation in DTR or other mutual-help groups.

School gardens have beneficial effects on children's dietary behaviors but information on its implementation is scarce. The current study aimed to gain insight in implementation practices of school gardens and in perceptions of key members and children towards a school garden. We conducted twelve interviews involving 14 key members and five focus groups with 38 children from fifth to sixth grade (10-13 years old) in four primary schools in Ghent (Flanders, Belgium). We analyzed the interviews and focus groups in NVivo, using thematic analysis. School gardens were mainly initiated to involve children in nature, not to improve vegetable consumption. Participants were positive about having a school garden, experienced facilitating factors (e.g., adaptability of the garden, having a person responsible for the garden), but also various barriers (e.g., difficulties with startup, maintenance during summer holidays and integration in the school curriculum) and suggested some solutions (e.g., involving external organizations and parents, expanding the garden) and motivating factors for children (e.g., colorful plants, use of gloves). In order to improve implementation and to contribute to children's health, future school gardening projects should take the recommendations of key members and children into account.

Concerns about dose and underutilization of twelve-step programs: models, scales, and theory that inform treatment planning.

PubMed

Cloud, Richard N; Kingree, J B

2008-01-01

Researchers have observed that a majority of addicted persons who are encouraged and facilitated by treatment providers to attend twelve-step (TS) programs either drop out or sporadically use twelve-step programs following treatment. This is troubling given considerable evidence of TS program benefits associated with regular weekly attendance and ubiquitous reliance by treatment professionals on these programs to provide important support services. This chapter reviews and advances theory of TS utilization and dose that is supported by prior research, multivariate models, and scales that predict risk of TS meeting underutilization. Advancing theory should organize and clarify the process of initial utilization, guide intervention development, and improve adherence of TS program referrals, all of which should lead to improved treatment planning and better outcomes. Three theories are integrated to explain processes that may influence TS program dose: the health belief model, self-determination theory (motivational theory), and a person-in-organization cultural fit theory. Four multidimensional scales developed specifically to predict participation are described. Implications for practice and future research are considered in a final discussion. Information contained in this chapter raises awareness of the need for TS-focused treatments to focus on achieving weekly attendance during and after treatment.

Communication skills play a key role in many aspects of both medical education and clinical patient care. The objectives of this study were to identify the key components of communication skills from the perspectives of both orthopaedic residents and their program directors and to understand how these skills are currently taught. This study utilized a mixed methods design. Quantitative data were collected with use of a thirty-item questionnaire distributed to all Canadian orthopaedic residents. Qualitative data were collected through focus groups with orthopaedic residents and semistructured interviews with orthopaedic program directors. One hundred and nineteen (37%) of 325 questionnaires were completed, twelve residents participated in two focus groups, and nine of sixteen program directors from across the country were interviewed. Both program directors and residents identified communication skills as being the accurate and appropriate use of language (i.e., content skills), not how the communication was presented (i.e., process skills). Perceived barriers to effective communication included time constraints and the need to adapt to the many personalities and types of people encountered daily in the hospital. Residents rarely have explicit training in communication skills. They rely on communication training implicitly taught through observation of their preceptors and clinical experience interacting with patients, peers, and other health-care professionals. Orthopaedic residents and program directors focus on content and flexibility within communication skills as well as on the importance of being concise. They value the development of communication skills in the clinical environment through experiential learning and role modeling. Education should focus on developing residents' process skills in communication. Care should be taken to avoid large-group didactic teaching sessions, which are perceived as ineffective.

Most rotator cuff surgery is performed on chronic tears. As there is no animal model in which to examine the physiology of muscle and tendon injury and repair in this setting, we developed a chronic rotator cuff injury model in sheep. The infraspinatus tendon was released in thirty-six female sheep. Biopsy specimens were obtained from the muscle and were analyzed for fat content. The force generated by the muscle with supramaximal stimulation was recorded intraoperatively. A control group (twelve sheep) underwent an immediate tendon repair. In the remaining twenty-four sheep, the tendon was wrapped in a dura substitute to prevent scarring and was repaired at six weeks (eight sheep) and eighteen weeks (sixteen sheep) after release. In the immediate repair group, four animals were killed at six weeks; four, at twelve weeks; and four, at twenty weeks. In the six-week delayed repair group, four animals were killed at twelve weeks and four were killed at twenty weeks after the repair. In the eighteen-week delayed repair group, eight animals were killed at twelve weeks; four, at twenty weeks; and four, at thirty weeks after the repair. Muscle biopsies and testing were repeated prior to killing of the animals. The average force of muscle contraction decreased 3.6 lb (1.6 kg) by six weeks after the injury and 3.9 lb (1.8 kg) by eighteen weeks after the injury. After the repair, the force of contraction in the six-week group improved by 0.8 lb (0.4 kg) at twelve weeks postoperatively and by 1.3 lb (0.6 kg) at twenty weeks postoperatively. In contrast, no improvement occurred in the eighteen-week group until thirty weeks after the repair, at which time a 0.9-lb (0.4-kg) improvement was noted. There was a twelvefold increase in intramuscular fat concentration; this lipid infiltration was partially reversed after the tendon repair. Isolated tendon samples demonstrated an increase in the modulus of elasticity after chronic detachment that partially corrected after the tendon repair in the earlier (six-week) repair group. We found that earlier repair of the tendon results in a more rapid recovery of both muscle function and tendon elasticity compared with a more delayed repair. We concluded that there may be a "point of no return" in rotator cuff injury after which the elasticity of the muscle-tendon unit does not return to normal.

Both general and subspecialty paediatric trainees undertake attachments in highly specialised tertiary hospitals. Trainee feedback suggests that mismatches in expectations between trainees and supervisors and a perceived lack of educational opportunities may lead to trainee dissatisfaction in such settings. With the 'Shape of Training' review (reshaping postgraduate training in the UK to focus on more general themes), this issue is likely to become more apparent. We wished to explore the factors that contribute to a positive educational environment and training experience and identify how this may be improved in highly specialised settings. General paediatric trainees working at all levels in subspecialty teams at a tertiary hospital were recruited (n=12). Semistructured interviews were undertaken to explore the strengths and weaknesses of training in such a setting and how this could be optimised. Appreciative inquiry methodology was used to identify areas of perceived best practice and consider how these could be promoted and disseminated. Twelve best practice themes were identified: (1) managing expectations by acknowledging the challenges; (2) educational contracting to identify learning needs and opportunities; (3) creative educational supervision; (4) centralised teaching events; (5) signposting learning opportunities; (6) curriculum-mapped pan-hospital teaching programmes; (7) local faculty groups with trainee representation; (8) interprofessional learning; (9) pastoral support systems; (10) crossover weeks to increase clinical exposure; (11) adequate clinical supervision; and (12) rota design to include teaching and clinic time. Tertiary settings have strengths, as well as challenges, for general paediatric training. Twelve trainee-generated tips have been identified to capitalise on the educational potential within these settings. Trainee feedback is essential to diagnose and improve educational environments and appreciative inquiry is a useful tool for this purpose.

Although recognized as a vulnerable population, there is no national population size estimate for sex workers in South Africa. A rapid sex worker enumeration exercise was undertaken in twelve locations across the country based on principles of participatory mapping and Wisdom of the Crowd. Sites with a range of characteristics were selected, focusing on level of urbanisation, trucking, mining and borders. At each site, sex worker focus groups mapped local hotspots. Interviews with sex workers at identified hotspots were used to estimate the numbers and genders of sex workers working in each. Estimates provided in the literature were combined with enumeration exercise results to define assumptions that could be applied to a national extrapolation. A working estimate was reached of between 131,000 and 182,000 sex worker in South Africa, or between 0.76 and 1 % of the adult female population. The success of the exercise depended on integral involvement of sex worker peer educators and strong ethical considerations.

The aim of this animal study was to compare the effects of narrow, concave-straight and wide anatomic healing abutments on changes to soft tissues and crestal bone levels around implants immediately placed into extraction sockets in foxhound dogs. Forty-eight titanium implants (Bredent Medical GMBH, Germany) of the same dimensions were placed in six foxhound dogs. They were divided into two groups (n = 24): test (implants with anatomic abutment) and control (implants with concave-straight abutment). The implants were inserted randomly in the post extraction sockets of P2 , P3 , P4, and M1 bilaterally in six dogs. After eight and twelve weeks, the animals were sacrificed and samples extracted containing the implants and the surrounding soft and hard tissues. Soft tissue and crestal bone loss (CBL) were evaluated by histology and histomorphometry. All implants were clinically and histologically osseointegrated. Healing patterns were examined microscopically at eight and twelve weeks. After eight and twelve weeks, for hard tissues, the distance from the implant shoulder to the first bone-to-implant contact (IS-C) was higher for control group in the lingual aspect with statistical significance (P < 0.05). For soft tissues (STL), the distance from the top of the peri-implant mucosa to the apical portion of the junction epithelium (PM-Je) was significantly less on the lingual aspect in the test group (with wider abutment) at eight and twelve weeks (P < 0.05). The distance from the top of the apical portion of the junction epithelium to the first bone-to-implant contact (Je-C) was significantly higher in the test group (wider abutment) in the lingual aspect at eight and twelve weeks (P < 0.05). There was no connective tissue contact with any abutment surface. Within the limitations of this animal study, anatomic healing abutments protect soft and hard tissues and reduce crestal bone resorption compared with concave-straight healing abutments. © 2014 John Wiley & Sons A/S.

The H1N1 pandemic: media frames, stigmatization and coping.

McCauley, Michael; Minsky, Sara; Viswanath, Kasisomayajula

Throughout history, people have soothed their fear of disease outbreaks by searching for someone to blame. Such was the case with the April 2009 H1N1 flu outbreak. Mexicans and other Latinos living in the US were quickly stigmatized by non-Latinos as carriers of the virus, partly because of news reports on the outbreak's alleged origin in Mexican pig farms. In this exploratory study we examined the psychological processes of cue convergence and associative priming, through which many people likely conflated news of the H1N1 outbreak with pre-existing cognitive scripts that blamed Latino immigrants for a variety of social problems. We also used a transactional model of stress and coping to analyze the transcripts from five focus groups, in order to examine the ways in which a diverse collection of New England residents appraised the threat of H1N1, processed information about stereotypes and stigmas, and devised personal strategies to cope with these stressors. Twelve themes emerged in the final wave of coding, with most of them appearing at distinctive points in the stress and coping trajectories of focus group participants. Primary and secondary appraisals were mostly stressful or negative, with participants born in the USA reporting more stressful responses than those who were not. Latino participants reported no stressful primary appraisals, but spoke much more often than Whites or Non-Hispanic Blacks about negative secondary appraisals. When interactions between participants dealt with stigmas regarding Latinos and H1N1, Latinos in our focus groups reported using far more negative coping strategies than Whites or Non-Hispanic Blacks. When discussions did not focus on stereotypes or stigmas, Latino participants spoke much more often about positive coping strategies compared to members of these same groups. Participants in all five focus groups went through a similar process of stress and coping in response to the threat of H1N1, though individual responses varied by race and ethnicity. Stigmatization has often been common during pandemics, and public health and emergency preparedness practitioners can help to mitigate its impacts by developing interventions to address the social stressors that occur during outbreaks in highly-localized geographic regions.

Thematic findings were identified. four key themes were: 'Guiding women over breast-feeding hurdles', 'Timing, and time to care'; 'Continuity of women's care' and 'Imparting professional knowledge'. Given the a pattern of hospital discharge of mother and infant on day one or day two after birth, participants thought the timing of immediate postnatal breast-feeding support was critical to enable women to initiate and continue breast feeding. Community-based MCH nurses reported time gaps in uptake of new mother referrals and time-pressured face-to-face consultations. Both groups perceived barriers to continuity of women's care. health services subscribe to the Baby Friendly Health Initiative and government policies which support breast feeding, however providers described time pressures and a lack of continuity of women's care, including during transition from hospital to community services. there is a need to examine administration of service delivery and how domiciliary and community nurses can collaborate to establish and maintain supportive relationships with breast feeding women.

Combining medically assisted treatment and Twelve-Step programming: a perspective and review.

Galanter, Marc

2018-01-01

People with severe substance use disorders require long-term rehabilitative care after the initial treatment. There is, however, a deficit in the availability of such care. This may be due both to inadequate medical coverage and insufficient use of community-based Twelve-Step programs in many treatment facilities. In order to address this deficit, rehabilitative care for severe substance use disorders could be promoted through collaboration between practitioners of medically assisted treatment, employing medications, and Twelve-Step-oriented practitioners. To describe the limitations and benefits in applying biomedical approaches and Twelve-Step resources in the rehabilitation of persons with severe substance use disorders; and to assess how the two approaches can be employed together to improve clinical outcome. Empirical literature focusing on clinical and manpower issues is reviewed with regard (a) to limitations in available treatment options in ambulatory and residential addiction treatment facilities for persons with severe substance use disorders, (b) problems of long-term rehabilitation particular to opioid-dependent persons, associated with the limitations of pharmacologic approaches, (c) the relative effectiveness of biomedical and Twelve-Step approaches in the clinical context, and (d) the potential for enhanced use of these approaches, singly and in combination, to address perceived deficits. The biomedical and Twelve-Step-oriented approaches are based on differing theoretical and empirically grounded models. Research-based opportunities are reviewed for improving addiction rehabilitation resources with enhanced collaboration between practitioners of these two potentially complementary practice models. This can involve medications for both acute and chronic treatment for substances for which such medications are available, and Twelve-Step-based support for abstinence and long-term rehabilitation. Clinical and Scientific Significance: Criteria for developing evidence-based approaches for combined treatment should be developed, and research for evidence-based treatment on this basis can be undertaken in order to develop improved clinical outcome.

Club head speed (CHS) is a major determinant of drive distance, a key component of golf performance. The purpose of this study was to determine the indirect effects of an eight-week strength and power program on CHS. Twelve (6 male, 6 female) NCAA Division II golfers (20.3±1.5 years) randomly assigned to an intervention or control group, underwent either a periodized strength and power program consisting of high-load barbell movements or a bodyweight and rotational movement focused resistance training program. Outcomes were CHS, countermovement jump (CMJ) height, and 1RM back squat (BS), power clean (PC), and deadlift (DL). Dependent t-tests were utilized to assess differences in outcome variables pre-to-post for each group, independent t-tests were utilized to assess differences between groups, and Pearson correlations were utilized to assess associations between CHS and outcome variables. On average, the intervention group experienced improvements in all outcome variables except peak CHS (p=0.60); the control group displayed no changes in any outcome variable except a decrease in average CHS (p=0.028). Compared to the control group, the intervention group experienced greater improvements in average CHS, BS, PC, and average and peak CMJ height (p<0.05). Additionally, CHS had large associations with PC (r=0.70, p=0.012), BS (r=0.64, p=0.025), DL (r=0.54, p=0.068) and CMJ (r=0.73, p=0.007). These results suggest improving muscular strength and power by increasing PC, BS, and CMJ is associated with increased CHS in collegiate golfers. Integrating a high-load, barbell-focused strength and power program may be beneficial for improving CHS and indirectly, golf performance.

Multispectral scanner data in twelve spectral channels, in the wavelength range 0.46 to 11.7 mm, acquired in July 1971 for three flightlines, were analyzed by applying automatic pattern recognition techniques. These twelve spectral channels were divided into four wavelength groups (W1, W2, W3 and W4), each consisting of three wavelength channels -- with respect to their estimated probability of correct classification (P sub c) in discriminating agricultural cover types. The same analysis was also done for the data acquired in August, to investigate the effect of time on these results. The effect of deletion of each of the wavelength groups on P sub C in the subsets of one to nine channels, is given. Values of P sub C for all possible combinations of wavelength groups, in the subsets of one to eleven channels are also given.

GLACE is a model intercomparison study focusing on a typically neglected yet critical element of numerical weather and climate modeling: land-atmosphere coupling strength, or the degree to which anomalies in land surface state (e.g., soil moisture) can affect rainfall generation and other atmospheric processes. The twelve AGCM groups participating in GLACE performed a series of simple numerical experiments that allow the objective quantification of this element. The derived coupling strengths vary widely. Some similarity, however, is found in the spatial patterns generated by the models, enough similarity to pinpoint multi-model "hot spots" of land-atmosphere coupling. For boreal summer, such hot spots for precipitation and temperature are found over large regions of Africa, central North America and India; a hot spot for temperature is also found over eastern China. The design of the GLACE simulations are described in full detail so that any interested modeling group can repeat them easily and thereby place their model s coupling strength within the broad range of those documented here.

A state-of-the-art review of the management and treatment of taste and smell alterations in adult oncology patients.

Thorne, Trina; Olson, Karin; Wismer, Wendy

2015-09-01

The purpose of this review was to examine studies of interventions for the prevention and management of taste and smell alterations (TSA) experienced by adult oncology patients. Articles published between 1993 and 2013 were identified by searching CINAHL, MEDLINE and Food Science & Technology Abstracts (FSTA) and were included if they were in English and focused on adult oncology patients. Only interventions within the scope of nursing practice were reviewed. Twelve articles were identified for inclusion. Four research groups examined zinc supplementation, with two claiming that zinc supplementation was an effective intervention and two claiming it had no effect on TSA. The remaining research groups examined eight other interventions, with varying results. Marinol, megestrol acetate and Synsepalum dulcificum interventions appear promising. Based on this review, there does not yet appear to be an effective approach for preventing or managing TSA in adult oncology patients. Although some interventions show promise, further research is necessary to determine their efficacy.

Patient-related outcome measures (PROMs) are commonly used to gauge treatment effects in patients with anterior cruciate ligament (ACL) deficiency. Valid measures of specific conditions depend on relevant item content. While item content can be derived either from clinicians (face validity) or from patients, item relevance and comprehensiveness can only be confirmed by the patient (content validity). Focus group and single interviews were conducted with patients' pre- and post-ACL reconstruction in order to construct a condition-specific PROM for the target patients. One hundred fifty-seven items from a previously conducted literature search were used as a basis for content genesis. Content saturation was achieved after three focus groups and seven single interviews. Thirty-eight items from the literature search were directly endorsed, and five modified items were endorsed. Twelve new item themes with verbatim content emerged. Thus, a 55-item pilot PROM consisting of six conceptual domains was assembled. We have constructed a condition-specific PROM for measurement of surgical and non-surgical treatment effects on ACL deficiency. The instrument possesses face and content validity. A pilot survey to assess the psychometric properties will be performed using Rasch measurement theory. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Traditional food products (TFP) are an important part of European culture, identity, and heritage. In order to maintain and expand the market share of TFP, further improvement in safety, health, or convenience is needed by means of different innovations. The aim of this study was to obtain a consumer-driven definition for the concept of TFP and innovation and to compare these across six European countries (Belgium, France, Italy, Norway, Poland and Spain) by means of semantic and textual statistical analyses. Twelve focus groups were performed, two per country, under similar conditions. The transcriptions obtained were submitted to an ordinary semantic analysis and to a textual statistical analysis using the software ALCESTE. Four main dimensions were identified for the concept of TFP: habit-natural, origin-locality, processing-elaboration and sensory properties. Five dimensions emerged around the concept of innovation: novelty-change, variety, processing-technology, origin-ethnicity and convenience. TFP were similarly perceived in the countries analysed, while some differences were detected for the concept of innovation. Semantic and statistical analyses of the focus groups led to similar results for both concepts. In some cases and according to the consumers' point of view the application of innovations may damage the traditional character of TFP.

Objectives Global health research into the relationship between health, economic inequalities, and globalization is necessary to address increasing health disparities in low income countries. Nicaragua has high levels of poverty and extreme poverty when compared with other Central and South American Countries. Design Photovoice and ethnographic research methods were used to explore health experiences of Creole women in Bluefields, Nicaragua and the intersections between culture, socioeconomic status, and gender. Sample Twelve Creole women participants, ages 18–45. Measurements After initial focus groups, participants used disposable cameras to document health experiences. Follow up interviews were conducted about the meaning of each photo. Participants then selected photos to be included in a city-wide photoshow. Results In initial focus groups, participants described great distress over changes they perceived in Creole culture and how these changes affect the health of the next generation. Participants related most of these changes to the economy and globalization. Photos taken were primarily of aspects of Creole culture, including household practices and traditional remedies from Creole culture. Conclusions Findings on the relationships between culture, disease and community-identified health risks in this minority population can help healthcare providers and public health policy makers develop and sustain culturally appropriate health interventions.

There is growing recognition that a more sophisticated information technology (IT) infrastructure is needed to improve the quality of nursing home care in the United States. The purpose of this study was to explore the concept of IT sophistication in nursing homes considering the level of technological diversity, maturity and level of integration in resident care, clinical support, and administration. Twelve IT stakeholders were interviewed from 4 nursing homes considered to have high IT sophistication using focus groups and key informant interviews. Common themes were derived using qualitative analytics and axial coding from field notes collected during interviews and focus groups. Respondents echoed the diversity of the innovative IT systems being implemented; these included resident alerting mechanisms for clinical decision support, enhanced reporting capabilities of patient-provider interactions, remote monitoring, and networking among affiliated providers. Nursing home IT is in its early stages of adoption; early adopters are beginning to realize benefits across clinical domains including resident care, clinical support, and administrative activities. The most important thread emerging from these discussions was the need for further interface development between IT systems to enhance integrity and connectivity. The study shows that some early adopters of sophisticated IT systems in nursing homes are beginning to achieve added benefit for resident care, clinical support, and administrative activities.

All health and social care professionals learn on the job through both formal and informal learning processes, which contributes to continuous professional development (CPD). This study explored workplace learning in General Practices, specifically looking at the role of informal learning and the workplace practices that appear to support or restrict that learning, as well as how technology was integrated into these learning processes. Three focus groups with general practitioners, practice nurses, managerial and administrative staff were conducted followed by twelve individual semi-structured interviews with participants drawn from the focus groups. Three observations of multi-disciplinary team meetings were used to establish potential team-based learning activities. Triggers for informal workplace learning included patients presenting challenging or unusual conditions; exposure to others' professional practice; and policy driven changes through revised guidance and protocols. By exploring how these triggers were acted upon, we identified mechanisms through which the primary care workplace supports or restricts informal learning through working practices, existing technologies and inter-professional structures. Informal workplace learning was identified as arising from both opportunistic encounters and more planned activities, which are both supported and restricted through a variety of mechanisms. Maximising informal learning opportunities and removing barriers to doing so should be a priority for primary care practitioners, managers and educators.

An in-depth understanding of the citizen's perception and behavior is needed for the development of targeted public policies and interventions that can successfully encourage people to shift their dietary patterns and contribute to the prevention of non-communicable diseases. The present work aimed to identify barriers and facilitators for the adoption of the new Uruguayan dietary guidelines from a citizen perspective. Twelve semistructured focus groups were conducted with a total of 91 people (81% female, age 18-64 years) from 3 Uruguayan cities. Findings identified several multifaceted barriers, including lack of value given to food, meals and cooking, taste preferences for unhealthy foods, the unsupportive social context in terms of household preferences, customs and social norms, and lack of control of the situation through insufficient food capabilities, time scarcity, and an adverse food market environment. The potential facilitators discussed in the focus groups were mainly related to policies and regulations to discourage consumption of unhealthful products and the provision of more education and information. In addition, respondents acknowledged the need for own actions in terms of seeking greater cooking skills and enjoyment, incorporating changes in their daily routines and promoting a more supportive social environment. Results suggest that supportive actions are needed to support citizen's adoption of the new Uruguayan dietary guidelines.

2016-09-01

To combat childhood obesity, researchers have focused on parental feeding practices that promote child health. The current study investigated how parenting style relates to twelve parental feeding practices. Data on parenting style and parental feeding practices were obtained for a correlational study from users of Amazon's Mechanical Turk, an online survey system. USA. Mothers of children aged 7-11 years (n 193). Parenting style related differentially to eleven out of the twelve measured practices. Authoritative mothers displayed more feeding practices that promote child health and fewer practices that impede child health. Authoritarian and permissive mothers displayed more unhealthy practices than authoritative mothers, but differed from each other on the practices they employed. Parenting style may relate to more aspects of feeding than previously realized. The inclusion of numerous healthy feeding practices along with unhealthy practices in the current study provides suggestions for the application of healthy feeding behaviours. Instruction on feeding behaviours and parenting style should be a focus of future educational programmes.

The aim of this work was to analyze muscle strength in Pilates novices who used the Reformer equipment during twelve training sessions. Twenty-four healthy young female volunteers, who were non-smokers and did not exercise regularly, were split into a control group (mean age 28 ± 4 years and BMI 24.55 ± 3.21 kg/m 2 ) and a training group (mean age 29 ± 4 years and BMI 22.69 ± 2.87 kgm 2 ). The data were checked for normality using the Kolmogorov-Smirnov test, and were then analyzed using the t-test (p < 0.05). After the training sessions, there were statistically significant differences between the groups for the scapular stabilizer muscles (p = 0.0263) and the lumbar muscles (p = 0.0001). For the scapular stabilizers, the initial/final values were 14.69 ± 2.80/14.79 ± 2.89 (control group) and 15.99 ± 3.54/17.44 ± 2.88 (Pilates group). The corresponding values for the lumbar muscles were 53.83 ± 11.66/53.28 ± 11.14 (control group) and 54.75 ± 10.27/64.80 ± 10.20 (Pilates group). After twelve sessions of Pilates with the Reformer equipment, there were improvements in lumbar extensor and scapular stabilizer strength. Several benefits are reported by practitioners of Pilates, but until now, there has been limited scientific evidence of the improvement of strength in the trunk and limbs after application of the technique.

[Purpose] This study evaluated the effects of topical oxygen therapy on the hind limb wounds of rats under ischemic conditions. [Subjects and Methods] Twelve injured rats were treated with topical oxygen on skin wounds located on the hind limb and compared with twelve injured control rats. Indexes including gross morphology of the wound, wound healing time, wound healing rate, and histological and immunohistochemical staining of sections of wound tissue were examined at different time points after intervention. [Results] The wound healing time was shorter in the topical oxygen therapy group than the control group. The wound healing rate and granulation tissue formation in the topical oxygen therapy group showed significant improvement on days 3, 7, and 14. Through van Gieson staining, the accumulation of collagen fiber in the topical oxygen therapy group was found to have improved when compared with the control group on day 7. Through semiquantitative immunohistochemical staining, many more new vessels were found in the topical oxygen therapy group compared with the model control group on day 7. [Conclusion] The results of the experiment showed that topical oxygen therapy improved ischemic wound healing.

In this paper, twelve dialkyltartrate-boric acid complexes and two polyols-boric acid complexes were in situ synthesized by the reaction of different dialkyltartrates or polyols with boric acid in methanol containing triethylamine. All of the twelve dialkyltartrate-boric acid complexes were found to have relatively good chiral separation performance in nonaqueous capillary electrophoresis (NACE). Their chiral recognition effects in terms of both enantioselectivity (α) and resolution (R(s)) were similar when the number of carbon atoms was below six in the alkyl group of alcohol moiety. The dialkyltartrates containing alkyl groups of different structures but the same number of carbon atoms, i.e. one of straight chain and one of branched chain, also provided similar chiral recognition effects. Furthermore, it was demonstrated for the first time that two methanol insoluble polyols, D-mannitol and D-sorbitol, could react with boric acid to prepare chiral ion-pair selectors using methanol as the solvent medium.

Cardiopulmonary capacities of twelve adults (aged between 14 to 44 years) with varying degrees of blindness engaged in regular recreational activities were compared with twelve age-matched normal sighted healthy males (control group) who were also involved in regular recreational activities. Maximum oxygen consumption (VO2max) was measured directly during exhaustive exercise test on a cycle ergometer. Forced vital capacity, leg strength and power were determined by spirometry, standing long jump and vertical jump respectively. No significant differences in VO2max, forced vital capacity and leg strength and power were observed between the blind and the control groups. No anthropometric differences were evident between the two groups. The results show therefore that the visually handicapped who are active can have a similar level of physical fitness, lung function and explosive leg strength as those of their active sighted counterparts.

To describe the process of integration and revision of a pediatric program curriculum which resulted in the creation of a competency-based framework recommended in the Brazilian National Curricular Guidelines. Quali-quantitative analysis of an intervention evaluating the students and professors' perception of the pediatric program curriculum (focus groups and semi-structured interviews). Results were discussed during teaching development workshops. A competency-based framework was suggested for the pediatric program from the 3rd to the 6th year. The new curriculum was approved, implemented, and reevaluated six months later. Twelve students (12%) from the 3rd to the 6th year participated in the focus groups, and 11 professors (78.5%) answered the questionnaire. Most participants reported lack of integration among the courses, lack of knowledge about the learning goals of the internships, few opportunities of practice, and predominance of theoretical evaluation. In the training workshops, a competency-based curriculum was created after pediatrics and collective health professors reached an agreement. The new curriculum was focused on general competency, learning goals, opportunities available to learn these goals, and evaluation system. After six months, 93% (104/112) of students and 79% (11/14) of professors reported greater integration of the program and highlighted the inclusion of the clinical performance evaluation. The collective creation of a competency-based curriculum promoted higher satisfaction of students and professors. After being implemented, the new curriculum was considered to integrate the teaching practices and contents, improving the quality of the clinical performance evaluation.

Objective A mixed methods study exploring the UK general public's willingness to donate human biosamples (HBSs) for biomedical research. Setting Cross-sectional focus groups followed by an online survey. Participants Twelve focus groups (81 participants) selectively sampled to reflect a range of demographic groups; 1110 survey responders recruited through a stratified sampling method with quotas set on sex, age, geographical location, socioeconomic group and ethnicity. Main outcome measures (1) Identify participants’ willingness to donate HBSs for biomedical research, (2) explore acceptability towards donating different types of HBSs in various settings and (3) explore preferences regarding use and access to HBSs. Results 87% of survey participants thought donation of HBSs was important and 75% wanted to be asked to donate in general. Responders who self-reported having some or good knowledge of the medical research process were significantly more likely to want to donate (p<0.001). Reasons why focus group participants saw donation as important included: it was a good way of reciprocating for the medical treatment received; it was an important way of developing drugs and treatments; residual tissue would otherwise go to waste and they or their family members might benefit. The most controversial types of HBSs to donate included: brain post mortem (29% would donate), eyes post mortem (35%), embryos (44%), spare eggs (48%) and sperm (58%). Regarding the use of samples, there were concerns over animal research (34%), research conducted outside the UK (35%), and research conducted by pharmaceutical companies (56%), although education and discussion were found to alleviate such concerns. Conclusions There is a high level of public support and willingness to donate HBSs for biomedical research. Underlying concerns exist regarding the use of certain types of HBSs and conditions under which they are used. Improved education and more controlled forms of consent for sensitive samples may mitigate such concerns. PMID:23929915

Ovaries are highly complex organs displaying morphological, molecular and functional differences between their cortical zona parenchymatosa and medullary zona vasculosa, and also between the different cyclic luteal stages. Objective of the present study was to validate expression stability of twelve putative reference genes (RGs) in bovine ovaries, considering the intrinsic heterogeneity of bovine ovarian tissue with regard to different luteal stages and intra-ovarian localizations. The focus was on identifying RGs, which are suitable to normalize RT-qPCR results of ovaries collected from clinical healthy cattle, irrespective of localization and the hormonal stage. Expression profiles of twelve potential reference genes (GAPDH, ACTB, YWHAZ, HPRT1, SDHA, UBA52, POLR2C, RPS9, ACTG2, H3F3B, RPS18 and RPL19) were analysed. Evaluation of gene expression differences was performed using genorm, normfinder, and bestkeeper software. The most stably expressed genes according to genorm, normfinder and bestkeeper approaches contained the candidates H3F3B, RPS9, YWHAZ, RPS18, POLR2C and UBA52. Of this group, the genes YWHAZ, H3F3B and RPS9 could be recommended as best-suited RGs for normalization purposes on healthy bovine ovaries irrespective of the luteal stage or intra-ovarian localization. © 2014 Blackwell Verlag GmbH.

The first year after severe burn is a psychologically challenging period for the patient. Patients may still struggle with burn-related physical and psychological problems such as posttraumatic stress disorder (PTSD) and body image dissatisfaction (BID). This study investigates the presence of PTSD, BID and coping, at three, six and twelve months after discharge for early identification of patients in need of focused support during rehabilitation. Fifty-two adult patients with different degrees of burns were followed at three, six and twelve months after discharge and 36 patients completed all assessment points. A standardized clinical protocol was used for systematic assessment of PTSD (IES-R), BID (SWAP-Swe) and Coping (CBQ). The follow-up included an intervention with a burn nurse as a complement to the existing program. Approximately half of the patients had a risk of developing PTSD three months after discharge from hospital, and body image dissatisfaction was found to potentially predict risk of PTSD during follow-up. The findings suggest that it is important to include patients with less extensive burns in follow-up as this group is at risk of development of PTSD. Using standardized questionnaires in early follow-up along with assessment of body image dissatisfaction may facilitate detection of psychological problems. Copyright © 2016 Elsevier Ltd and ISBI.

Very few large national epidemiologic surveys have examined the prevalence of psychiatric disorders among Asians and Native Americans due to small sample sizes. Very little is also known about the co-occurrences between substance use disorders and mood and anxiety disorders among these two minority groups and how their rates compare to Whites, Blacks, and Hispanics. Analyses were based on a large (n = 43093) nationally representative survey of the adult (18+ years), U.S. population supplemented by a group quarters sampling frame. Prevalences and associations of major DSM-IV mood, anxiety and substance use disorders were examined among all major race/ethnic subgroups of the population. Twelve-month rates of most mood, anxiety and substance use disorders were generally greatest among Native Americans and lowest among Asians. For most race/ethnic subgroups, alcohol and drug dependence, but not abuse, were significantly associated with mood disorders. With few exceptions, there were no significant associations between alcohol and drug abuse and anxiety disorders. In contrast, alcohol dependence was associated with most anxiety disorders among Whites, Blacks and Asians, but not among Native Americans. The 12-month prevalence of substance use, mood, and anxiety disorders varied greatly across the five major race/ethnic subgroups of the population. Twelve-month co-occurrence of substance use disorders and mood and anxiety disorders was pervasive among all race/ethnic subgroups. Future research is also needed to understand race/ethnic differentials in prevalence and co-occurrence of these disorders with a particular focus on factors that may give rise to them.

The present study examined the influence of attentional focus on performance during a long-distance throwing task. Twelve participants executed three maximum-effort, long-distance baseball throwing attempts in three focus conditions: internal focus on wrist flexion (wrist internal focus), internal focus on the separation between pelvis and upper torso orientations (torso internal focus), and external focus on the ball path (external focus). Compared with the external focus and torso internal focus conditions, performance was poorer in the wrist internal focus condition. Performances were not different in the torso internal and external focus conditions. In addition, attentional focus affected the release angle of the ball but not its initial velocity. Our results reveal that the body part targeted for internal focus of attention and the forcefulness of the motor activity can be as important to motor performance as whether the attention is internal or external.

Introduction An important yet understudied component of postpartum type 2 diabetes risk reduction among high risk women is experiences with the healthcare system. Our objective was to describe the healthcare experiences of a diverse, low-income sample of women with prior GDM, including their suggestions for improving care. Methods Focus groups were conducted among African American, Hispanic, and Appalachian women who were diagnosed with GDM within the past 10 years. Participants were recruited from community and medical resources. Twelve focus groups were conducted, four within each race-ethnic group. Results Three broad themes were identified around barriers to GDM care, management, and follow-up: (1) communication issues; (2) personal and environmental barriers; and (3) type and quality of healthcare. Many women felt communication with their provider could be improved, including more education on the severity of GDM, streamlining information to be less overwhelming, and providing additional support through referrals to community resources. Although women expressed interest in receiving more actionable advice for managing GDM during pregnancy and for preventing type 2 diabetes postpartum, few women reported changing behaviors. Barriers to behavior change were related to cost, transportation, and competing demands. Several opportunities for improved care were elucidated. Discussion Our findings suggest that across all racial and ethnic representations in our sample, low-income women with GDM experience similar communication, personal, and environmental barriers related to the healthcare they receive for their GDM. Considering the increased exposure to the health care system during a GDM-affected pregnancy, there are opportunities to address barriers among women with GDM across different race-ethnic groups.

Lost in translation: a focus group study of parents' and adolescents' interpretations of underage drinking and parental supply.

Reductions in underage drinking will only come about from changes in the social and cultural environment. Despite decades of messages discouraging parental supply, parents perceive social norms supportive of allowing children to consume alcohol in 'safe' environments. Twelve focus groups conducted in a regional community in NSW, Australia; four with parents of teenagers (n = 27; 70 % female) and eight with adolescents (n = 47; 55 % female). Participants were recruited using local media. Groups explored knowledge and attitudes and around alcohol consumption by, and parental supply of alcohol to, underage teenagers; and discussed materials from previous campaigns targeting adolescents and parents. Parents and adolescents perceived teen drinking to be a common behaviour within the community, but applied moral judgements to these behaviours. Younger adolescents expressed more negative views of teen drinkers and parents who supply alcohol than older adolescents. Adolescents and parents perceived those who 'provide alcohol' (other families) as bad parents, and those who 'teach responsible drinking' (themselves) as good people. Both groups expressed a preference for high-fear, victim-blaming messages that targeted 'those people' whose behaviours are problematic. In developing and testing interventions to address underage drinking, it is essential to ensure the target audience perceive themselves to be the target audience. If we do not have a shared understanding of underage 'drinking' and parental 'provision', such messages will continue to be perceived by parents who are trying to do the 'right' thing as targeting a different behaviour and tacitly supporting their decision to provide their children with alcohol.

2017-02-26

To compare the treatment outcomes of DSM-IV-TR schizophrenia patients in either a Community Treatment Program or an Individual Treatment Program (CTP vs. ITP). The assessment was made after the first hospitalization, and then after three and twelve years. Participants were randomly assigned to CTP (experimental) and ITP (traditional) group, with 40 people in each group. 67 people (84%) participated in all three assessments. The socio-demographic and clinical indicators were the same for both groups. In the first three years only the CTP group participated in day-care treatment, patient and family psychoeducation and community treatment. Later, both groups received this treatment. The following tools were used: Anamnestic and Catamnestic Questionnaire, the GAF scale, the BPRS LA and Lehman's Quality of Life Interview. It was only after twelve years that there was a significant beneficial improvement in the mean GAF score in the CTP group (p = 0.036), which was comparable with the results obtained by Watt and Shepherd for the course of the illness in favorable remission cases (p = 0.038). The difference in the number of relapses was also significantly in favor of the CTP group only after 12 years (p = 0.045), as was the difference in the number of rehospitalizations (p = 0.013). The general severity of symptoms was found to be significantly lower for the CPT group after 3 (p = 0.008) and 12 years (p = 0.030), whereas it was significantly lower in the case of positive syndrome only after 3 years (p = 0.044). 1. A greater number of favorable differences were identified for the CTP group at the twelve-year point than at the conclusion of the experiment. 2. The three-year delay in introducing psycho-social treatment was associated with a poorer long-term outcome for the clinical course of schizophrenia.

NeoCart, an autologous cartilage tissue implant, compared with microfracture for treatment of distal femoral cartilage lesions: an FDA phase-II prospective, randomized clinical trial after two years.

2012-06-06

Despite introduction of autologous chondrocyte therapy for repair of hyaline articular cartilage injury in 1994, microfracture remains a primary standard of care. NeoCart, an autologous cartilage tissue implant, was compared with microfracture in a multisite prospective, randomized trial of a tissue-engineered bioimplant for treating articular cartilage injuries in the knee. Thirty patients were randomized at a ratio of two to one (two were treated with an autologous cartilage tissue implant [NeoCart] for each patient treated with microfracture) at the time of arthroscopic confirmation of an International Cartilage Repair Society (ICRS) grade-III lesion(s). Microfracture or cartilage biopsy was performed. NeoCart, produced by seeding a type-I collagen matrix scaffold with autogenous chondrocytes and bioreactor treatment, was implanted six weeks following arthroscopic cartilage biopsy. Standard evaluations were performed with validated clinical outcomes measures. Three, six, twelve, and twenty-four-month data are reported. The mean duration of follow-up (and standard deviation) was 26 ± 2 months. There were twenty-one patients in the NeoCart group and nine in the microfracture group. The mean age (40 ± 9 years), body mass index (BMI) (28 ± 4 kg/m2), duration between the first symptoms and treatment (3 ± 5 years), and lesion size (287 ± 138 mm2 in the NeoCart group and 252 ± 135 mm2 in the microfracture group) were similar between the groups. Adverse event rates per procedure did not differ between the treatment arms. The scores on the Short Form-36 (SF-36), Knee Injury and Osteoarthritis Outcome Score (KOOS) activities of daily living (ADL) scale, and International Knee Documentation Committee (IKDC) form improved from baseline (p < 0.05) to two years postoperatively in both treatment groups. In the NeoCart group, improvement, compared with baseline, was significant (p < 0.05) for all measures at six, twelve, and twenty-four months. Improvement in the NeoCart group was significantly greater (p < 0.05) than that in the microfracture group for the KOOS pain score at six, twelve, and twenty-four months; the KOOS symptom score at six months; the IKDC, KOOS sports, and visual analog scale (VAS) pain scores at twelve and twenty-four months; and the KOOS quality of life (QOL) score at twenty-four months. Analysis of covariance (ANCOVA) at one year indicated that the change in the KOOS pain (p = 0.016) and IKDC (p = 0.028) scores from pretreatment levels favored the NeoCart group. Significantly more NeoCart-treated patients (p = 0.0125) had responded to therapy (were therapeutic responders) at six months (43% versus 25% in the microfracture group) and twelve months (76% versus 22% in the microfracture group). This trend continued, as the proportion of NeoCart-treated patients (fifteen of nineteen) who were therapeutic responders at twenty-four months was greater than the proportion of microfracture-treated participants (four of nine) who were therapeutic responders at that time. This randomized study suggests that the safety of autologous cartilage tissue implantation, with use of the NeoCart technique, is similar to that of microfracture surgery and is associated with greater clinical efficacy at two years after treatment.

The H1N1 pandemic: media frames, stigmatization and coping

PubMed Central

2013-01-01

Background Throughout history, people have soothed their fear of disease outbreaks by searching for someone to blame. Such was the case with the April 2009 H1N1 flu outbreak. Mexicans and other Latinos living in the US were quickly stigmatized by non-Latinos as carriers of the virus, partly because of news reports on the outbreak’s alleged origin in Mexican pig farms. Methods In this exploratory study we examined the psychological processes of cue convergence and associative priming, through which many people likely conflated news of the H1N1 outbreak with pre-existing cognitive scripts that blamed Latino immigrants for a variety of social problems. We also used a transactional model of stress and coping to analyze the transcripts from five focus groups, in order to examine the ways in which a diverse collection of New England residents appraised the threat of H1N1, processed information about stereotypes and stigmas, and devised personal strategies to cope with these stressors. Results Twelve themes emerged in the final wave of coding, with most of them appearing at distinctive points in the stress and coping trajectories of focus group participants. Primary and secondary appraisals were mostly stressful or negative, with participants born in the USA reporting more stressful responses than those who were not. Latino participants reported no stressful primary appraisals, but spoke much more often than Whites or Non-Hispanic Blacks about negative secondary appraisals. When interactions between participants dealt with stigmas regarding Latinos and H1N1, Latinos in our focus groups reported using far more negative coping strategies than Whites or Non-Hispanic Blacks. When discussions did not focus on stereotypes or stigmas, Latino participants spoke much more often about positive coping strategies compared to members of these same groups. Conclusions Participants in all five focus groups went through a similar process of stress and coping in response to the threat of H1N1, though individual responses varied by race and ethnicity. Stigmatization has often been common during pandemics, and public health and emergency preparedness practitioners can help to mitigate its impacts by developing interventions to address the social stressors that occur during outbreaks in highly-localized geographic regions.

2018-01-01

The present study investigated word-initial (WI) /r/-clusters in Central Swedish-speaking children with and without protracted phonological development (PPD). Data for WI singleton /r/ and singleton and cluster /l/ served as comparisons. Participants were twelve 4-year-olds with PPD and twelve age- and gender-matched typically developing (TD) controls. Native speakers audio-recorded and transcribed 109 target single words using a Swedish phonology test with 12 WI C+/r/-clusters and three WI CC+/r/-clusters. The results showed significantly higher match scores for the TD children, a lower match proportion for the /r/ targets and for singletons compared with clusters, and differences in mismatch patterns between the groups. There were no matches for /r/-cluster targets in the PPD group, with all children except two in that group showing deletions for both /r/-cluster types. The differences in mismatch proportions and types between the PPD group and controls suggests new directions for future clinical practice.

A qualitative descriptive study of the group prenatal care experience: perceptions of women with low-risk pregnancies and their midwives.

Group prenatal care (GPC) originated in 1994 as an innovative model of prenatal care delivery. In GPC, eight to twelve pregnant women of similar gestational age meet with a health care provider to receive their prenatal check-up and education in a group setting. GPC offers significant health benefits in comparison to traditional, one-on-one prenatal care. Women in GPC actively engage in their healthcare and experience a supportive network with one another. The purpose of this study was to better understand the GPC experience of women and care providers in a lower risk group of women than often has been previously studied. This qualitative descriptive study collected data through three focus group interviews--two with women who had completed GPC at a midwifery clinic in Ontario, Canada and one with the midwives at the clinic. Data was analyzed through open coding to identify themes. Nine women and five midwives participated in the focus groups, from which eight categories as well as further subcategories were identified: The women and midwives noted reasons for participating (connections, education, efficiency). Participants suggested both benefits (learning from the group, normalizing the pregnancy experience, preparedness for labour and delivery, and improved relationships as all contributing to positive health outcomes) and concerns with GPC (e.g. sufficient time with the midwife) which generally diminished with experience. Suggestions for change focused on content, environment, partners, and access to the midwives. Challenges to providing GPC included scheduling and systems-level issues such as funding and regulation. Flexibility and commitment to the model facilitated it. Comparison with other models of care identified less of a relationship with the midwife, but more information received. In promoting GPC, women would emphasize the philosophy of care to other women and the midwives would promote the reduction in workload and women's independence to colleagues. Overall, women and midwives expressed a high level of satisfaction with their GPC experience. This study gained insight into previously unexplored areas of the GPC experience, perceptions of processes that contribute to positive health outcomes, strategies to promote GPC and elements that enhance the feasibility of GPC.

This study examines health and health care attitudes, practices and utilization patterns among the Bedouin Arab minority in the south of Israel. Particular attention is given to the effects of the new National Insurance Law that provides universal coverage for the first time, and to the identification of critical issues for further research. Focus groups, adapted to Bedouin culture, were the primary method of data collection. Twelve groups (158 participants) from throughout the Negev met for 3-7 sessions each, using specially trained local moderators and observers. Issues discussed and analyzed included experience and satisfaction with the current health system (both modern and traditional), health service availability/barriers, health care needs, influences of social change, and the National Insurance Law. Participants voice dissatisfaction with modern health services in the Bedouin sector and the state of health of Negev Bedouin. They place great emphasis on the connection between health and the rapid social and economic changes, which this traditionally nomadic group is undergoing. Traditional health care is felt to still exist, but its importance is waning. The National Insurance law is having a major impact on the Bedouin, particularly because it provides universal health insurance coverage where only partial coverage had been in effect. This study, one of the first of its kind in the Bedouin sector, showed that the focus group method, if properly modified to cultural norms, can be a valuable research tool in traditional communities and in health service research. The findings from this research can be used to direct efforts to improve health policy and health services for this group, as well as preparing the way for further qualitative or quantitative studies.

Purpose The purpose of this pilot study was to determine the feasibility of offering our Diabetes Coaching Program (DCP), adapted for African Americans, in a sample of African American adults with type 2 diabetes. Methods The study utilized a one-group, pretest-posttest design to test the acceptance and potential effectiveness of the DCP. Subjects were a convenience sample of 16 African Americans (8 females; 8 males) with type 2 diabetes; twelve subjects (6 females; 6 males) completed the program. The DCP included four weekly class sessions devoted to resilience education and diabetes self-management, followed by eight biweekly support group meetings. Psychosocial process variables (resilience, coping strategies, diabetes empowerment), and proximal (perceived stress, depressive symptoms, diabetes self-management) and distal outcomes (BMI, fasting blood glucose, HbA1c, lipidemia, blood pressure) were assessed at baseline and six-months post study entry. Qualitative data were collected at eight-months via a focus group conducted to examine the acceptability of the DCP. Results Preliminary paired t-tests indicated statistically significant improvements in diabetes empowerment, diabetes self-management, BMI, HbA1c, total cholesterol, LDL-cholesterol, and systolic and diastolic blood pressure. Medium to large effect sizes were reported. Resilience, perceived stress, fasting blood glucose, and HDL-cholesterol improved, but changes were not statistically significant. Focus group data confirmed that participants held positive opinions regarding the DCP and follow-up support group sessions, although they suggested an increase in program length from 4 to 8 weeks. Conclusions The pilot study documented the feasibility and potential effectiveness of the DCP to enhance diabetes empowerment, diabetes self-management, and reductions in the progression of obesity, type 2 diabetes, and CVD in the African American community. Randomized experimental designs are needed to confirm these findings. PMID:19204102

Emergency medical practices are often team efforts. Training for various tasks and collaborations may be carried out in virtual environments. Although promising results exist from studies of serious games, little is known about the subjective reactions of learners when using multiplayer virtual world (MVW) training in medicine. The objective of this study was to reach a better understanding of the learners' reactions and experiences when using an MVW for team training of cardiopulmonary resuscitation (CPR). Twelve Swedish medical students participated in semistructured focus group discussions after CPR training in an MVW with partially preset options. The students' perceptions and feelings related to use of this educational tool were investigated. Using qualitative methodology, discussions were analyzed by a phenomenological data-driven approach. Quality measures included negotiations, back-and-forth reading, triangulation, and validation with the informants. Four categories characterizing the students' experiences could be defined: (1) Focused Mental Training, (2) Interface Diverting Focus From Training, (3) Benefits of Practicing in a Group, and (4) Easy Loss of Focus When Passive. We interpreted the results, compared them to findings of others, and propose advantages and risks of using virtual worlds for learning. Beneficial aspects of learning CPR in a virtual world were confirmed. To achieve high participant engagement and create good conditions for training, well-established procedures should be practiced. Furthermore, students should be kept in an active mode and frequent feedback should be utilized. It cannot be completely ruled out that the use of virtual training may contribute to erroneous self-beliefs that can affect later clinical performance. ©Johan Creutzfeldt, Leif Hedman, Li Felländer-Tsai.

Background Serological follow-up of acute Q-fever patients is important for detection of chronic infection but there is no consensus on its frequency and duration. The 2007–2009 Q-fever epidemic in the Netherlands allowed for long-term follow-up of a large cohort of acute Q-fever patients. The aim of this study was to validate the current follow-up strategy targeted to identify patients with chronic Q-fever. Methods A cohort of adult acute Q-fever patients, diagnosed between 2007 and 2009, for whom a twelve-month follow-up sample was available, was invited to complete a questionnaire and provide a blood sample, four years after the acute episode. Antibody profiles, determined by immunofluorescence assay in serum, were investigated with a special focus on high titres of IgG antibodies against phase I of Coxiella burnetii, as these are considered indicative for possible chronic Q-fever. Results Of the invited 1,907 patients fulfilling inclusion criteria, 1,289 (67.6%) were included in the analysis. At any time during the four-year follow-up period, 58 (4.5%) patients were classified as possible, probable, or proven chronic Q-fever according to the Dutch Q-fever Consensus Group criteria (which uses IgG phase I ≥1:1,024 to as serologic criterion for chronic Q-fever). Fifty-two (89.7%) of these were identified within the first year after the acute episode. Of the six patients that were detected for the first time at four-year follow-up, five had an IgG phase I titre of 1:512 at twelve months. Conclusions A twelve-month follow-up check after acute Q-fever is recommended as it adequately detects chronic Q-fever in patients without known risk factors. Additional serological and clinical follow-up is recommended for patients with IgG phase I ≥1:512, as they showed the highest risk to progress to chronic Q-fever. PMID:26161658

The aim of this study was to investigate the impact of consuming dairy yogurt containing Lactobacillus paracasei ssp. paracasei ( L. paracasei ), Bifidobacterium animalis ssp. lactis ( B. lactis ) and heat-treated Lactobacillus plantarum ( L. plantarum ) on immune function. A randomized, open-label, placebo-controlled study was conducted on 200 nondiabetic subjects. Over a twelve-week period, the test group consumed dairy yogurt containing probiotics each day, whereas the placebo group consumed milk. Natural killer (NK) cell activity, interleukin (IL)-12 and immunoglobulin (Ig) G1 levels were significantly increased in the test group at twelve weeks compared to baseline. Additionally, the test group had significantly greater increases in serum NK cell activity and interferon (IFN)-γ and IgG1 than placebo group. Daily consumption of dairy yogurt containing L. paracasei , B. lactis and heat-treated L. plantarum could be an effective option to improve immune function by enhancing NK cell function and IFN-γ concentration (ClinicalTrials.gov: NCT03051425).

When coexpressed with its cognate amber suppressing tRNACUAPyl, a pyrrolysyl-tRNA synthetase mutant N346A/C348A is able to genetically incorporate twelve meta-substituted phenylalanine derivatives into proteins site-specifically at amber mutation sites in Escherichia coli. These genetically encoded noncanonical amino acids resemble phenylalanine in size and contain diverse bioorthogonal functional groups such as halide, trifluoromethyl, nitrile, nitro, ketone, alkyne, and azide moieties. The genetic installation of these functional groups in proteins provides multiple ways to site-selectively label proteins with biophysical and biochemical probes for their functional investigations. We demonstrate that a genetically incorporated trifluoromethyl group can be used as a sensitive 19F NMR probe to study protein folding/unfolding, and that genetically incorporated reactive functional groups such as ketone, alkyne, and azide moieties can be applied to site-specifically label proteins with florescent probes. This critical discovery allows the synthesis of proteins with diverse bioorthogonal functional groups for a variety of basic studies and biotechnology development using a single recombinant expression system.

The impact of music on human cognition has a distinguished history as a research topic in psychology. The focus of the present study was on investigating the effects of music instruction on the cognitive development of preschool children. From a sample of 154 preschool children of Tehran kindergartens, 60 children aged between 5 and 6 were randomly assigned to two groups, one receiving music lessons and the other (matched for sex, age and mother's educational level) not taking part in any music classes. Children were tested before the start of the course of music lessons and at its end with 4 subtests of the Tehran-Stanford-Binet Intelligence Scale (TSB). The experimental group participated in twelve 75-min weekly music lessons. Statistical analysis showed significant IQ increase in participants receiving music lessons, specifically on the TSB verbal reasoning and short-term memory subtests. The numerical and visual/abstract reasoning abilities did not differ for the two groups after lessons. These data support studies that found similar skills enhancements in preschool children, despite vast differences in the setting in which the instruction occurred. These findings appear to be consistent with some neuroimaging and neurological observations which are discussed in the paper.

According to recent studies, Spanish adolescents show low perception of risk in alcohol consumption. The current study aims to analyze the factors that favor this low perception based on the opinion of a group of 32 professional experts on adolescence, family, school, mass media, and local policies. A qualitative methodology was used, based on Grounded Theory, using information from 5 focus groups guided by semi-structured interviews. Twelve factors or subcategories were identified, grouped in 4 general categories: short-term risk, immediacy, and perception of invulnerability ("adolescent thinking" category); benevolent view of alcohol, normalization of consumption, and alcohol-entertainment binomial ("social norms" category); parents' habitual consumption, verbal/non-verbal inconsistency in parental model, risk-free consumption depicted in the mass media, consumption with positive results in the media ("social models" category); and excessive health content, long-term risk ("preventive discourse" category). After discussing the results in the context of the current scientific literature, the article offers various proposals for increasing risk perception in adolescents: stronger impact of contents on short-term risks of alcohol; educational strategies targeted to adolescents to include agents of socialization, especially parents; and policies centered on the substance and reduction of supply.

The changing face of bipolar disorder: adolescence to adulthood.

2008-02-01

Over the past decade, there has been greater acceptance of the existence of bipolar disorder (BD) in adolescents. The onset of BD during this period severely affects the acquisition of key developmental skills. Debate around diagnosis, comorbidity and treatment is strong and little is known about the long-term impact BD has on an adolescents as they approach adulthood, from both illness and functional perspectives. A review of psychological and medical databases using the search terms ''adolescent onset'', ''pediatric onset'', ''juvenile onset'', ''bipolar disorder'', ''course'' and ''outcome'' was conducted. Emphasis was placed on the information available from studies, which have described the outcome of adolescent onset BD either prospectively, retrospectively, or both. Twelve studies were identified that focused on the long-term course of adolescent onset BD. Findings on the course and outcomes are conflicting. These studies are from few centres or research groups and have small sample sizes, varied methodologies and relatively brief follow-up durations. There are few studies available on the course and outcome of adolescent onset BD. Although there seems to be less controversy in this age group compared to the prepubertal age group, there remains a need for prospective studies of large systematically ascertained samples.

The purpose of the pilot study was to determine the effect of restoring lost occlusal vertical dimension (OVD) due to attrition on maximum bite force in humans. A total of 124 subjects in age range of 25-40 years, with moderate to severe attrition, having full complement of teeth were screened according to inclusion and exclusion criteria. After consent, occlusal vertical dimension was assessed by employing mechanical and physiological methods in the experimental group and a maxillary canine guided hard splint was fabricated for each subjects fulfilling inclusion criteria and with positive consent (78). Bite force in experimental group was measured before, immediately after delivery of splint and subsequently at an interval of four, eight, and twelve weeks. Due loss during follow up, only 50 subjects could be available for bite force recording till 12 weeks. Bite force of age, gender, height and weight matched controls with no signs of attrition was also measured for comparison. Bite force of the experimental group was found to be significantly less than the matched controls (P=0.000) initially. After delivery of splint, bite force values increased progressively till twelve weeks. However comparison of bite force values of experimental group with control group showed no significant difference at end of eight (P=0.008) and twelve weeks (P=0.162). It was concluded that maximum bite force increases with restoration of lost vertical using splint therapy. A time period of 8-12 weeks is required to restore the maximum bite force value approximately similar to matched controls. Copyright © 2012 Japan Prosthodontic Society. Published by Elsevier Ltd.

The discovery of miRNAs has brought the focus of physiologists to post-transcriptional regulation of the skeletal muscle. However, the field of how miRNAs are involved in regulating mitochondrial biogenesis and apoptosis of the skeletal muscle following endurance training is still in its infancy. Twelve male C57BL/6 mice were randomly assigned to either control group (Group C) or voluntary wheel running group (Group E). The Group C was housed in cages mounted with fixed wheels, while mice of Group E were allowed to run on wheels freely for 8weeks. It was found that miR-494 and miR-696 were significantly decreased in the gastrocnemius muscle after 8week voluntary wheel exercise, accompanied with an increase in the mRNA expression of NRF1, BIM and Bcl-XL, an increase in the protein content of PGC-1α, and a decrease in the protein content BIM. The lack of correlation between miR-494 and TFAM and BIM, as well as between miR-696 and PGC-1α suggests that even though miR-494 and miR-696 are sensitive miRNAs in response to exercise training, other factors or miRNAs might also be important during the regulation of mitochondrial biogenesis and apoptosis.

The purpose of this study was to evaluate the efficacy of non-invasive methods of treatment for active incipent occlusal caries. Anamnesis, professional prophylaxis, and visual inspection were used to classify 250 Brazilian pre-school-children. First permanent decayed molars (n=98) from thirty-one subjects (6 years+ 6 months) were selected and divided into three groups. Group 1: fissure sealants with resin-modified glass ionomer - Vitremer (n=29); Group 2: fluoride varnish -Duraphat (n=36) and control group: tooth brushing and 0.2 percent NaF weekly mouthwashes (n=33). Four clinical evaluations were carried out over three, six, nine, and twelve months. Caries activity and progression were observed through clinical and radiographic evaluation. The results were analyzed by Fisher=s Exact test. After twelve months, the results showed 100 percent of arrestment of caries activity for Group 1, 83.3 percent for group 2, and 72.7 percent for control group. At the same time, the results showed 0 percent of caries progression for group 1, 5.5 percent for Group 2, and 6.1 percent for control group. Group 1 showed a better inactivation property than the other groups (p<0.05). There were no statistically significant differences in caries progression among these groups (p>0.05). It was concluded that this non-invasive methods were able to arrest the progression of occlusal caries, but fissure sealant showed better results in controlling caries activity.

2016-12-01

Refugees and new immigrants arriving in the United States (U.S.) often encounter a multitude of stressors adjusting to a new country and potentially coping with past traumas. Community gardens have been celebrated for their role in improving physical and emotional health, and in the Twin Cities of Minnesota, have been offered as a resource to immigrants and refugees. The purpose of this study is to present a mixed method evaluation of a refugee gardening project hosted by area churches serving primarily Karen and Bhutanese populations. Quantitative data were obtained from early and late season surveys (44 and 45 % response rates, respectively), and seven focus groups conducted at the end of the season provided qualitative data. Although few gardeners (4 %) identified food insecurity as a problem, 86 % indicated that they received some food subsidy, and 78 % reported vegetable intake increased between the early and late season surveys. Twelve percent of gardeners indicated possible depression using the PHQ-2 scale; in focus groups numerous respondents identified the gardens as a healing space for their depression or anxiety. Refugee gardeners expressed receiving physical and emotional benefits from gardening, including a sense of identity with their former selves. Gardens may serve as a meaningful health promotion intervention for refugees and immigrants adjusting to the complexity of their new lives in the U.S. and coping with past traumas.

I report an action research study that aimed at improving Thai pre-service teachers' understanding of the relationship between science and religion and at assisting them to respond to this issue in a science classroom. The participants were twelve post-grad students pursuing Master of Art in Teaching Science at Kasetsart University. They took a course, Philosophy of Science, taught by the researcher in Semester A, academic year 2007. Process drama is the teaching strategy employed. The students were fully engaged in the process drama; doing research, producing, distributing, and criticizing the drama. Focus group, student journal, and observation were used to gather the data and the data was analyzed using qualitative analysis techniques. The focus groups revealed that the drama could help students reflect on the complexity and sensitivity of the issue. They found there was no inherent conflict between science and religion since they answered different questions and used different methods to achieve their results. However, the conflicts occurred when people were not aware of the basic differences between the two so they justified one on the basis of purpose and method of one another. The pre-service teachers also found consistency between science and Buddhism. They thought that the teachers of science should respond to the conflicts in a respectful, compromising, and neutral manner.[InlineMediaObject not available: see fulltext.

The twelve 1-n-pentyl-2-, 3-, 4-, 5-, 6- and 7-(1- and 2-naphthoyl)-indoles each have the same substituents attached to the indole ring, identical elemental composition (C24H23NO) yielding identical nominal and accurate masses. These twelve isomers cover all possible positions of carbonyl bridge substitution for both indole (positons 2-7) and naphthalene rings (positions 1 and 2). Regioisomeric compounds can represent significant challenges for mass based analytical methods however, infrared spectroscopy is a powerful tool for the identification of positional isomers in organic compounds. The vapor phase infrared spectra of these twelve uniquely similar compounds were evaluated in GC-IR experiments. These spectra show the bridge position on the indole ring is a dominating influence over the carbonyl absorption frequency observed for these compounds. Substitution on the pyrrole moiety of the indole ring yields the lowest Cdbnd O frequency values for position 2 and 3 giving a narrow range from 1656 to 1654 cm-1. Carbonyl absorption frequencies are higher when the naphthoyl group is attached to the benzene portion of the indole ring yielding absorption values from 1674 to 1671 cm-1. The aliphatic stretching bands in the 2900 cm-1 region yield a consistent triplet pattern because the N-alkyl substituent tail group remains unchanged for all twelve regioisomers. The asymmetric CH2 stretch is the most intense of these three bands. Changes in positional bonding for both the indole and naphthalene ring systems results in unique patterns within the 700 wavenumber out-of-plane region and these absorption bands are different for all 12 regioisomers.

This study aimed to assess whether teaching good cooking practices, food habits and sanitation to ultra-poor rural women in four rural communities of Rangpur district, Bangladesh, with a high density of extremely poor households, would improve the overall health of the community. The sample size was 200 respondents combined from the target and control areas. In the target area, twelve in-depth interviews and four focus group discussions were undertaken for knowledge dissemination. Descriptive and mixed-model analyses were performed. The results show that washing hands with soap was 1.35 times more likely in the target than the control group (p<0.01). Further, after intervention, there was a significant improvement in hand-washing behaviour: before cutting vegetables, preparing food, feeding a child and eating, and after defecating and cleaning a baby (p<0.05). Also, the target group was more likely to moderately and briefly boil their vegetables and were 19% less likely to use maximum heat when cooking vegetables than the control group (p<0.01). Improved knowledge and skills training of ultra-poor women reduces the loss of nutrients during food preparation and increases their hygiene through hand-washing in every-day life.

Following the detection of two cases of members of 6 Chinese families having tested positive for the hepatitis B virus, a study of those living in these families was begun for the purpose of knowing the spread of the infection within the family environment of the cases detected. Descriptive study. Population under study: 24 members of six Chinese families. Age, sex, serological diagnosis, risk factors, healthcare-related attitude. Clinical records, serological data, epidemiological survey and immunization cards. A family focus was employed and the genogram used. Distribution Binomial spread for calculating probability of occurrence of the process to be studied. A total of 14 males (58.3%) and 10 females (41.7%) ranking from 1 to 54 years of age were studied. The age group having the largest number of subjects studied was the age 21-30 group (37.5%). Twelve chronic hepatitis B infections were recorded (50%). No relationship was found to exist with the risk factors studied in the epidemiological survey conducted. The probability of this number of chronic hepatitis cases occurring was 0.066 x 10(-6). It was concluded that the prevalence of infection found was probable due to intra-family transmission. Given the low probability of occurrence of a process of this type, the case grouping found is considered to be high.

Skills of novices early trained or traditionaly trained versus experienced drivers confronted to simulated urban accidents' scenarios.

PubMed

Berthelon, Catherine; Damm, Loïc

2012-01-01

In order to prevent the over-representation of young drivers in car crashes, France instated an early driver training from the age of 16, but the positive effects of this opportunity have not yet been proven. Three groups of male drivers (12 subjects each) were confronted with some prototypical accident scenarios introduced in a simulated urban circuit. The first and second groups were composed of young drivers having less than one month of driving licence; twelve have had a traditional learning course, and twelve had followed, in addition to the initial course, an early driver training under the supervision of an adult. The third group was composed of experienced drivers. Strategies of the three groups were analyzed through their response time, speed and maneuvers. No difference appeared across groups regarding obstacle detection. But traditionally-trained drivers' position control was more conservative than the two others groups, which were more likely to involve efficient evasive action. The exposure gained during early training could thus increase the development of visuo-motor coordination and involve better skills in case of difficult situations. Others accidents' scenarios could be used to confront young drivers with difficult situations not commonly encountered in natural driving.

Omissions and Byproducts across Moral Domains

PubMed Central

DeScioli, Peter; Asao, Kelly; Kurzban, Robert

2012-01-01

Research indicates that moral violations are judged less wrong when the violation results from omission as opposed to commission, and when the violation is a byproduct as opposed to a means to an end. Previous work examined these effects mainly for violent offenses such as killing. Here we investigate the generality of these effects across a range of moral violations including sexuality, food, property, and group loyalty. In Experiment 1, we observed omission effects in wrongness ratings for all of the twelve offenses investigated. In Experiments 2 and 3, we observed byproduct effects in wrongness ratings for seven and eight offenses (out of twelve), respectively, and we observed byproduct effects in forced-choice responses for all twelve offenses. Our results address an ongoing debate about whether different cognitive systems compute moral wrongness for different types of behaviors (surrounding violence, sexuality, food, etc.), or, alternatively, a common cognitive architecture computes wrongness for a variety of behaviors.

College versus the real world: student perceptions and implications for understanding heavy drinking among college students.

PubMed

Colby, Suzanne M; Colby, John J; Raymond, George A

2009-01-01

College student heavy drinking is a persistent problem despite widespread initiatives. Using focus group methodology, this study examined student perceptions of factors that promote and limit drinking during and after college. The goal was to better understand factors that reduce drinking post-college to develop strategies to moderate college drinking. Twelve groups (N=75) were conducted with undergraduates at a northeastern Catholic college. Most participants drank; the majority exceeded a clinical indicator of problematic drinking. Transcript analysis identified themes that were coded with high reliability. Drinking in college was perceived to enhance socialization, bonding, and disinhibition. College, characterized by a high level of freedom and low level of responsibility, was seen as time-out from the "real world". In that context, heavy drinking was permissible. Students expected their future lifestyle to be burdensome and tedious; nostalgia for the good times associated with heavy drinking was anticipated. They imagined post-college drinking to be a threat to career and family and therefore irresponsible. Implications for intervention development and future research are described.

The risk factors and precautions of inpatient suicide were explored. Thirty suicide victims were drawn from the adverse event reports of suicidal act during hospitalization in a general hospital from 2008 to 2014. Data were gathered from the focus group interviews of twelve nurses who had experienced inpatient suicide. The data were analyzed by using analytical technique based on grounded theory, and software QSR NVIVO8 was used to aid the collation of data. Three main themes of risk factors about inpatient suicide emerged from the analysis: individual value, social factors and environmental factors. The individual value was categorized into different groups such as sense of guilt, hopelessness and low self-esteem. Social factors included two aspects of negative life events and social support. Three themes of precautions about inpatient suicide appeared in this study: evaluation, nursing and information exchange. Evaluation was elaborated from both physical and psychological assessments. This finding extends existing work of risk factors and precautions about inpatient suicide and brings new knowledge about the reasons why inpatients commit suicide.

Despite numerous advances in the recognition, assessment, and management of pain in neonates over the past two decades, there has been limited improvement in the knowledge base regarding parental responses to their infant's pain. This study examined parents' views of their experiences observing and coping with their infant's pain in the neonatal intensive care unit (NICU). Twelve participants were recruited using purposive sampling from two groups: (a) parents who had infants currently receiving care in the NICU (n=6); and (b) parents whose infants had been discharged from the NICU and were enrolled in the outpatient follow-up clinic at each hospital (n=6). An exploratory, semi-structured format was used to interview parents individually (n=5) or in focus groups (n=7) regarding their infant's clinical course, infant pain experiences, and the parenting experience during and after the NICU stay. Thematic content analysis was used to develop conceptual categories. Two broad themes were identified: (a) infant pain as a source of parental distress and (b) relief of parental distress due to infant's pain.

Participatory research with indigenous communities in the Philippines.

Oxfam encourages its partners to integrate gender issues into their work. Accordingly, the organization drew a team of six researchers from local partners to conduct a gender-needs assessment in Arakan Valley, North Cotabo, on the island of Mindanao, Philippines. There are five million indigenous people in the Philippines belonging to more than forty different tribal groups. They are oppressed and exploited by foreign and local elites, with many having lost their ancestral lands to agribusiness plantations, ranches, mining and logging concessions of multinational corporations, and government projects. Focus group discussions, participant observation, key informant feedback, and case studies conducted over a twelve-month period found the existence of physical violence between husbands and wives; men typically having two-three wives, with women pressuring men to take more wives so that there will be more labor for farming and housework; incest is taboo, but it is not unusual for sisters to be married to one man; and women's labor responsibilities relative to men's have increased. Study results are being shared with participants in the local language.

To determine the effects of a six-month physical activity stimulation programme on social participation, self-perception and quality of life in children with cerebral palsy. Multicentre randomized controlled trial with concealed allocation, blinded assessments and intention-to-treat analysis. Paediatric physiotherapy practices, special schools for children with a disability, and the child's own home. Forty-nine children with spastic cerebral palsy (28 male), aged 7-13 years, able to walk with and without walking aids. The intervention group followed a six-month physical activity stimulation programme involving counselling through motivational interviewing, home-based physiotherapy and four months of fitness training. The control group continued regular paediatric physiotherapy. Outcomes included social participation in domestic life, social participation in recreation and leisure (Life-Habits for Children questionnaire and Children's Assessment of Participation and Enjoyment questionnaire), self-perception (Harter's Self-Perception Profile for Children) and parent-reported quality of life (Cerebral Palsy Quality of Life Questionnaire). Assessments were performed at baseline, at six months (except quality of life) and at twelve months. Intervention resulted in a positive effect on social participation in domestic life at twelve months (mean between-group difference = 0.9, 95% confidence interval (CI) = 0.1 to 1.7 [1-10 scale], P = 0.03), but not at six months. No significant effects were found for social participation in recreation and leisure, self-perception at six months and twelve months or for quality of life at twelve months. The combination of counselling, home-based physiotherapy and fitness training was not effective in improving social participation in recreation and leisure, self-perception or quality of life, but did show a potential for improving social participation in domestic life over the longer term. © The Author(s) 2013.

Nonpharmacological interventions, including combinations of music, education, coping skills, and relaxation techniques, have been found to have a positive effect on patients' perceived anxiety in many settings. However, few research studies have assessed and compared the effectiveness of music and relaxation interventions in reducing the anxiety levels of orthopaedic and oncology patients. We conducted a prospective, randomized, controlled study to examine the effectiveness of music and relaxation interventions on perceived anxiety during initial hospitalization for patients receiving orthopaedic or cancer care treatment at a Midwestern teaching hospital. This was a pre-test/post-test study design utilizing the State-Trait Anxiety Inventory. One hundred twelve patients were randomized into 3 study groups. Thirty-eight subjects (34%) were randomized in the music-focused relaxation group, 35 subjects (31%) in the music and video group, and 39 (35%) subjects in the control group. Fifty-seven (51%) were orthopaedic patients and 55 (49%) were oncology patients. Comparison of the 3 study groups showed no statistically significant differences with regard to patients' demographics. Although reduced anxiety levels were reported for all 3 groups postintervention, the differences were not statistically significant (p > .05). Also, there was no significant difference found between the perceived anxiety levels of patients admitted to the orthopaedic and oncology care units (p > .05). Finally, the results of the intragroup comparisons (regardless of the group assignment) showed a significant decrease in anxiety levels reported by all patients postintervention (p < .001). Music and relaxation interventions could be an additional tool in assisting patients to become less anxious during their hospital stay. Music focused relaxation and music and video are both valuable and cost-effective strategies that can assist the orthopaedic and oncology patient population. Identifying opportunities to make these interventions easily accessible to healthcare professionals can assist in the management of patient anxiety during hospitalization.

Quantum Physics Principles and Communication in the Acute Healthcare Setting: A Pilot Study.

PubMed

Helgeson, Heidi L; Peyerl, Colleen Kraft; Solheim-Witt, Marit

This pilot study explores whether clinician awareness of quantum physics principles could facilitate open communication between patients and providers. In the spirit of action research, this study was conceptualized with a holistic view of human health, using a mixed method design of grounded theory as an emergent method. Instrumentation includes surveys and a focus group discussion with twelve registered nurses working in an acute care hospital setting. Findings document that the preliminary core phenomenon, energy as information, influences communication in the healthcare environment. Key emergent themes include awareness, language, validation, open communication, strategies, coherence, incoherence and power. Research participants indicate that quantum physics principles provide a language and conceptual framework for improving their awareness of communication and interactions in the healthcare environment. Implications of this pilot study support the feasibility of future research and education on awareness of quantum physics principles in other clinical settings. Copyright © 2016 Elsevier Inc.

Perfetto, Eleanor M; Harris, Jason; Mullins, C Daniel; dosReis, Susan

2018-04-01

Patient engagement is a transformative strategy for improving value assessment. US value framework developers have increased engagement activities, but more needs to be learned about how to best achieve meaningful patient engagement in value assessment. The objective was to glean good practices in patient engagement emerging from patient community experiences, to be used in value assessment. The National Health Council Value Workgroup conducted a survey and held a focus group with its member advocacy organizations to gather experiences with value framework developers and views on emerging good practices. Ten of 13 organizations completed the survey; reporting 13 interactions with four framework developers. Most rated experiences as "good" to "very good." Emerging good practices included (1) engage early; (2) engage a range of patients; (3) leverage patient-provided information, data resources, and outreach mechanisms; (4) be transparent; and (5) appreciate and accommodate resource constraints. Twelve of 13 organizations participated in the focus group, and this produced 30 emerging good practices in four areas: (1) timing; (2) methodology and data; (3) partnering; and (4) characterizing engagement. Patient engagement was limited in early development of value frameworks but has increased in the past few years. Patient groups report positive experiences that can serve as emerging good practices. These groups also reported experienced challenges in their interactions and recommended good practices to mitigate those challenges. The growing pool of patient engagement experiences can be translated into good practices to advance a patient-centered, value-driven health care ecosystem. Lessons learned from these early experiences can help establish recommend emerging good practices that can eventually result in best practices and standards in the field.

2010-04-01

Twelve years ago we reported an electrical impedance baseline study related to age, sex and body locations. The results showed significant differences between different anatomical locations and ages. In this study, the same participants were recalled to explore how the skin had evolved at the individual level over time. A total of 50 subjects, divided into an older and a younger group, were recalled for measurements of electrical impedance at eight anatomical locations. Readings were taken with an electrical impedance spectrometer. Information was extracted from the impedance spectra using indices based on magnitude and phase at two frequencies as in the earlier study. All included body sites had undergone alterations over time, and the size of the changes varied at different locations. The results also showed that changes in the younger group were different over time compared with the older group. In conclusion: Electrical impedance can be used to monitor skin evolution over time and baseline characteristics differ between various locations.

Twelve month follow-up to a randomised controlled trial, in which the control group also received treatment. Community. Fifteen of twenty one original participants with post-stroke anxiety participated in a one year follow-up study. A self-help autogenic relaxation CD listened to five times a week for one month, immediately in the intervention group and after three months in the control group. Hospital Anxiety and Depression Scale-Anxiety subscale and the Telephone Interview of Cognitive Status for inclusion. Hospital Anxiety and Depression Scale-Anxiety subscale for outcome. All measures were administered by phone. Anxiety ratings reduced significantly between pre and post-intervention, and between pre-intervention and one year follow-up ( χ 2 (2) = 22.29, p < 0.001). Reductions in anxiety in stroke survivors who received a self-help autogenic relaxation CD appear to be maintained after one year.

Unpacking smokers' beliefs about addiction and nicotine: A qualitative study.

Evidence suggests that consumers correctly identify nicotine as addictive; however, many may also harbor misconceptions about its harmfulness. The majority of this evidence is based on survey data, however, which may be prone to some limitations. In the current study, we employed qualitative methods to examine, in their own words, smokers' beliefs about nicotine and addiction. Twelve 1-hr focus groups were conducted in 3 cities in the United States (Columbus, OH; New Orleans, LA; and Washington, DC) from October to November, 2014. Adult cigarette smokers (N = 108), defined as those who reported smoking cigarettes on every day or some days, were segmented by age group (18-25 years and ≥26 years) and tobacco-use behavior. Thematic, in-depth analysis of focus-group discussion transcripts was conducted. Participant demographic information was recorded. Results showed that smokers identify nicotine as a cause of addiction to cigarettes; however, they also attribute their addiction to other factors. When asked about nicotine's effects on the body, immediate physiological effects of smoking (e.g., stimulation, relaxation) were top of mind. Opinions varied in terms of whether nicotine itself was harmful or harmless; many were unsure and/or had not considered this question. Discussions revealed heterogeneity in smokers' beliefs as well as recognition of their own uncertainty and lack of knowledge. The current findings provide insight that smokers may not be as misinformed regarding the relative harms of nicotine and tobacco, as has been suggested by quantitative evidence. Implications for future research are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

This study investigated undergraduates'awareness about stroke, the effects of an educational intervention and the difference of measuring tests between recognition and recall. We chose a convenient sample from two classes. One of the classes, the recognition group, was tested by a close-ended questionnaire with multiple choices. The other class, the recall group, was tested via an open-ended questionnaire. Participants completed their pretest and first posttest before and right after the education intervention. Twelve weeks after the intervention, participants were tested again to assess the knowledge retention over time. Fifty six participants in the recognition group and 53 participants in the recall group completed all three tests. Before the intervention, all respondents in the recognition group could recognize three or more risk factors and at least one warning sign, but in the recall group were only 32% and 72% respectively. After the intervention, the mean scores of first posttest and second posttest were all significant higher than that of pretest in both groups (P less 0.001). Comparisons of mean score of same items in both groups, the mean score of recognition group was significantly higher than that of recall group at each test (all P less 0.001). The intervention improved participants'knowledge towards stroke, even twelve weeks later. Participants obtained higher scores with a close-ended questionnaire than those with an open-ended questionnaire.

Purpose: To evaluate and compare peri-implant health, marginal bone loss and success of immediate and delayed implant placement for rehabilitation with full-arch fixed prostheses. Material and Methods: The present study was a prospective, randomized, single-blind, clinical preliminary trial. Patients were randomized into two treatment groups. In Group A implants were placed immediately post-extraction and in Group B six months after extraction. The following control time-points were established: one week, six months and twelve months after loading. Measurements were taken of peri-implant crevicular fluid volume, plaque index, gingival retraction, keratinized mucosa, probing depth, modified gingival index and presence of mucositis. Implant success rates were evaluated for the two groups. The study sample included fifteen patients (nine women and six men) with a mean average age of 63.7 years. One hundred and forty-four implants were placed: 76 placed in healed sites and 68 placed immediately. Results: At the moment of prosthetic loading, keratinized mucosa width and probing depth were higher in immediate implants than delayed implants, with statistically significant differences. However, after six and twelve months, differences between groups had disappeared. Bone loss was 0.54 ± 0.39 mm for immediate implants and 0.66 ± 0.25 mm for delayed implants (p=0.201). No implants failed in either group. Conclusions: The present study with a short follow-up and a small sample yielded no statistically significant differences in implant success and peri-implant marginal bone loss between immediate and delayed implants with fixed full-arch prostheses. Peri-implant health showed no statistically significant differences for any of the studied parameters (crevicular fluid volume, plaque index, gingival retraction, keratinized mucosa, probing depth, modified gingival index and presence of mucositis) at the twelve-month follow-up. Key words:Immediate implants, delayed implants, peri-implant health, success rate. PMID:24316712

Brosseau, Lisa M; Fredrickson, Ann L; Casey, Mary Anne

2007-04-01

Owners of small manufacturing businesses from twelve industrial sectors (n=40) participated in focus groups. They most frequently read trade and local business publications; few regularly read or receive health and safety materials. They select business-related materials that are specific to their business, give them new ideas, or have information that is easy to use. Insurance companies and business associations are the most frequently mentioned sources of health and safety information. The most important aspects of a prototype newsletter are sponsorship, color and graphics, length and relevance. Most are positive about a university logo, because it indicates a trusted source. The front page should have a table of contents with short descriptions of articles and catchy headlines. A newsletter should take no more than ten minutes to read. Owners did not like articles that were written in first person, used quotes, were too personal or gave no solutions. Owners think a newsletter will be successful if it is targeted to their industry, shows costs, includes case studies about local businesses, isn't too academic, focuses on a different topic with each issue, and gives readers an opportunity to provide feedback.

A research on the effects of practicing Baduanjin on the lower extremities by using sEMG

Jin, Li; Li, Ran; Chen, Jing; Tian, Ye

2015-03-01

The purpose of this study was to evaluate the effects of practicing Baduanjin exercises on the lower extremities of subjects, using electromyography analysis, and values of IEMG were calculated. [Subjects] Forty, healthy adults were randomly assigned as subjects to two groups: SG (Study Group, n=20) who received twelve weeks of Baduanjin training, and CG (Control Group, n=20), who received no training. [Methods] A sixteen-channel sEMG system (ME6000, Mega Electronics Ltd., Kuopio, Finland) was selected to record and measure activity changes in two muscles (vastus medialis and vastus lateralis). [Results] After twelve-week of Baduanjin training, the results of this study showed that the SG group had significant increases in values of IEMG in second, fifth and seventh section of the Baduanjin exercises. In second section, the values of IEMG had increased for 56.95% in vastus lateralis (p < 0.05) and for 40.04% in vastus medialis (p < 0.05). In fifth section, the values of IEMG had increased for 37.61% in vastus lateralis (p < 0.05) and for 33.83% in vastus medialis (p < 0.05). In seventh section, the increasement of IEMG values was 47.19% in vastus lateralis (p < 0.05) and 49.31% in vastus medialis (p < 0.05). [Conclusion] This study indicated that performing twelve-week of Baduanjin training can significantly increase the strength and the physical function of the lower extremities among healthy adults. With no adverse events from exercise were reported during the training procedure, the safety and low intensity of Baduanjin exercise was also proved, it could be widely taken as an appropriate no-risk treatment exercise for healthy adults.

Health-Related Quality of Life, Self-Efficacy and Enjoyment Keep the Socially Vulnerable Physically Active in Community-Based Physical Activity Programs: A Sequential Cohort Study

Physical inactivity is most commonly found in socially vulnerable groups. Dutch policies target these groups through community-based health-enhancing physical activity (CBHEPA) programs. As robust evidence on the effectiveness of this approach is limited, this study investigated whether CBHEPA programs contribute to an increase in and the maintenance of physical activity in socially vulnerable groups. In four successive cohorts, starting at a six-month interval, 268 participants from 19 groups were monitored for twelve months in seven CBHEPA programs. Data collection was based on repeated questionnaires. Socio-economic indicators, program participation and coping ability were measured at baseline. Physical activity, health-related quality of life and on-going program participation were measured three times. Self-efficacy and enjoyment were measured at baseline and at twelve months. Statistical analyses were based on a quasi-RCT design (independent t-tests), a comparison of participants and dropouts (Mann-Whitney test), and multilevel modelling to assess change in individual physical activity, including group level characteristics. Participants of CBHEPA programs are socially vulnerable in terms of low education (48.6%), low income (52.4%), non-Dutch origin (64.6%) and health-related quality of life outcomes. Physical activity levels were not below the Dutch average. No increase in physical activity levels over time was observed. The multilevel models showed significant positive associations between health-related quality of life, self-efficacy and enjoyment, and leisure-time physical activity over time. Short CBHEPA programs (10–13 weeks) with multiple trainers and gender-homogeneous groups were associated with lower physical activity levels over time. At twelve months, dropouts' leisure-time physical activity levels were significantly lower compared to continuing participants, as were health-related quality of life, self-efficacy and enjoyment outcomes. BMI and care consumption scored significantly higher among dropouts. In conclusion, Dutch CBHEPA programs reach socially vulnerable, but not necessarily inactive, groups in terms of socio-economic and health-related quality of life outcomes. Our findings suggest that CBHEPA programs particularly contribute to physical activity maintenance in socially vulnerable groups, rather than to an increase in physical activity behaviour over time.

This work analyses the short-term physiological and neurophysiological effects of a brisk walking programme in ageing, healthy, active men. Twenty-one men 63 to 72 years of age were recruited and separated into 2 groups. One group performed a walking programme (WP) (n = 11) and another served as control (C) group (n = 10). The walking programme lasted for twelve weeks and included five sessions per week. Several parameters were assessed before and after the programme for the WP group. The same tests were performed (separated by twelve weeks) in group C. During each assessment, the subjects were put through static and dynamic balance tests, spatio-temporal gait analysis, body composition measurements and determination of aerobic capacity and bone mineral density. The statistic analysis showed a significant improvement in dynamic balance performance, especially in lateral sway when the subjects kept their eyes open, an increase of VO(2) max and loss of fat mass in the WP group. However, no alterations appeared in spatiotemporal gait characteristics, static balance performance, lean mass or bone mineral density (total body and hip). According to these results, this walking programme may have positive effects on preventing ageing subjects from falling.

Compassionate presence: The meaning of hematopoietic stem cell transplant nursing.

PubMed

Sabo, Brenda M

2011-04-01

Within oncology, working with patients who are suffering or at end-of-life has been recognized repeatedly as stress-inducing, yet there is little agreement on what specifically nurses may experience as a result of their work. Further, research focused on caring work within the context of hematopoietic stem cell transplant (HSCT) nursing is almost non-existent. In light of the gap, this interpretative phenomenological study focused on enhancing the knowledge and understanding of the effect(s) of nursing work on the psychosocial health and well being of HSCT nurses. An interpretative phenomenological design grounded in the work of Heidegger and van Manen was used to explore nursing work among HSCT nurses. Twelve nurses from three Canadian tertiary healthcare facilities participated in multiple interviews and focus groups. Thematic analysis resulted in the emergence of four core themes and one overarching novel theme, compassionate presence. The discussion provides an overview of the novel finding, compassionate presence, which challenges the notion that working with individuals who are suffering or at end-of-life inevitably leads to adverse psychosocial effects. Implications for practice, education and research are also provided. Compassionate presence emerged to suggest a potential buffering effect against adverse consequences of HSCT nursing work. This finding underscored the value of the relationship as an integral component of nursing work. Copyright © 2010 Elsevier Ltd. All rights reserved.

INTRODUCTION: In obsessive-compulsive disorder, early treatment discontinuation can hamper the effectiveness of first-line treatments. OBJECTIVE: This study aimed to investigate the clinical correlates of early treatment discontinuation among obsessive-compulsive disorder patients. METHODS: A group of patients who stopped taking selective serotonin reuptake inhibitors (SSRIs) or stopped participating in cognitive behavioral therapy before completion of the first twelve weeks (total n = 41; n = 16 for cognitive behavioral therapy and n = 25 for SSRIs) were compared with a paired sample of compliant patients (n = 41). Demographic and clinical characteristics were obtained at baseline using structured clinical interviews. Chi-square and Mann-Whitney tests were used when indicated. Variables presenting a p value <0.15 for the difference between groups were selected for inclusion in a logistic regression analysis that used an interaction model with treatment dropout as the response variable. RESULTS: Agoraphobia was only present in one (2.4%) patient who completed the twelve-week therapy, whereas it was present in six (15.0%) patients who dropped out (p = 0.044). Social phobia was present in eight (19.5%) patients who completed the twelve-week therapy and eighteen (45%) patients who dropped out (p = 0.014). Generalized anxiety disorder was present in eight (19.5%) patients who completed the twelve-week therapy and twenty (50%) dropouts (p = 0.004), and somatization disorder was not present in any of the patients who completed the twelve-week therapy; however, it was present in six (15%) dropouts (p = 0.010). According to the logistic regression model, treatment modality (p = 0.05), agoraphobia, the Brown Assessment of Beliefs Scale scores (p = 0.03) and the Beck Anxiety Inventory (p = 0.02) scores were significantly associated with the probability of treatment discontinuation irrespective of interactions with other variables. DISCUSSION AND CONCLUSION: Early treatment discontinuation is a common phenomenon in obsessive-compulsive disorder patients from our therapeutic setting. Psychiatric comorbidities were associated with discontinuation rates of specific treatments. Future studies might use this information to improve management for increased compliance and treatment effectiveness. PMID:21552660

Background Multi-morbidity due to diabetes and chronic kidney disease (CKD) remains challenging for current health-systems, which focus on single diseases. As a first step toward health-care improvement, we explored the perspectives of patients and their carers on factors influencing the health-care of those with co-morbid diabetes and CKD. Methods In this qualitative study participants with co-morbid diabetes and CKD were purposively recruited using maximal variation sampling from 4 major tertiary health-services from 2 of Australia’s largest cities. Separate focus groups were conducted for patients with CKD stages 3, 4 and 5. Findings were triangulated with semi-structured interviews of carers of patients. Discussions were transcribed verbatim and thematically analysed. Results Twelve focus groups with 58 participants and 8 semi-structured interviews of carers were conducted. Factors influencing health-care of co-morbid diabetes and CKD grouped into patient and health service level factors. Key patient level factors identified were patient self-management, socio-economic situation, and adverse experiences related to co-morbid diabetes and CKD and its treatment. Key health service level factors were prevention and awareness of co-morbid diabetes and CKD, poor continuity and coordination of care, patient and carer empowerment, access and poor recognition of psychological co-morbidity. Health-service level factors varied according to CKD stage with poor continuity and coordination of care and patient and carer empowerment emphasized by participants with CKD stage 4 and 5, and access and poor recognition of psychological co-morbidity emphasised by participants with CKD stage 5 and carers. Conclusions According to patients and their carers the health-care of co-morbid diabetes and CKD may be improved via a preventive, patient-centred health-care model which promotes self-management and that has good access, continuity and coordination of care and identifies and manages psychological morbidity.

There is limited evidence to support the effectiveness of falls prevention interventions in the acute hospital setting. The 6-PACK falls prevention program includes a fall-risk tool; ‘falls alert’ signs; supervision of patients in the bathroom; ensuring patients’ walking aids are within reach; toileting regimes; low-low beds; and bed/chair alarms. This study explored the acceptability of the 6-PACK program from the perspective of nurses and senior staff prior to its implementation in a randomised controlled trial. A mixed-methods approach was applied involving 24 acute wards from six Australian hospitals. Participants were nurses working on participating wards and senior hospital staff including: Nurse Unit Managers; senior physicians; Directors of Nursing; and senior personnel involved in quality and safety or falls prevention. Information on program acceptability (suitability, practicality and benefits) was obtained by surveys, focus groups and interviews. Survey data were analysed descriptively, and focus group and interview data thematically. The survey response rate was 60%. Twelve focus groups (n = 96 nurses) and 24 interviews with senior staff were conducted. Falls were identified as a priority patient safety issue and nurses as key players in falls prevention. The 6-PACK program was perceived to offer practical benefits compared to current practice. Nurses agreed fall-risk tools, low-low beds and alert signs were useful for preventing falls (>70%). Views were mixed regarding positioning patients’ walking aid within reach. Practical issues raised included access to equipment; and risk of staff injury with low-low bed use. Bathroom supervision was seen to be beneficial, however not always practical. Views on the program appropriateness and benefits were consistent across nurses and senior staff. Staff perceived the 6-PACK program as suitable, practical and beneficial, and were open to adopting the program. Some practical concerns were raised highlighting issues to be addressed by the implementation plan. PMID:28199376

Background Health systems worldwide are facing shortages in health professional workforce. Several studies have demonstrated the direct correlation between the availability of health workers, coverage of health services, and population health outcomes. To address this shortage, online eLearning is increasingly being adopted in health professionals’ education. To inform policy–making, in online eLearning, we need to determine its effectiveness. Methods We performed a systematic review of the effectiveness of online eLearning through a comprehensive search of the major databases for randomised controlled trials that compared online eLearning to traditional learning or alternative learning methods. The search period was from January 2000 to August 2013. We included articles which primarily focused on students' knowledge, skills, satisfaction and attitudes toward eLearning and cost-effectiveness and adverse effects as secondary outcomes. Two reviewers independently extracted data from the included studies. Due to significant heterogeneity among the included studies, we presented our results as a narrative synthesis. Findings Fifty–nine studies, including 6750 students enrolled in medicine, dentistry, nursing, physical therapy and pharmacy studies, met the inclusion criteria. Twelve of the 50 studies testing knowledge gains found significantly higher gains in the online eLearning intervention groups compared to traditional learning, whereas 27 did not detect significant differences or found mixed results. Eleven studies did not test for differences. Six studies detected significantly higher skill gains in the online eLearning intervention groups, whilst 3 other studies testing skill gains did not detect differences between groups and 1 study showed mixed results. Twelve studies tested students' attitudes, of which 8 studies showed no differences in attitudes or preferences for online eLearning. Students' satisfaction was measured in 29 studies, 4 studies showed higher satisfaction for online eLearning and 20 studies showed no difference in satisfaction between online eLearning and traditional learning. Risk of bias was high for several of the included studies. Conclusion The current evidence base suggests that online eLearning is equivalent, possibly superior to traditional learning. These findings present a potential incentive for policy makers to cautiously encourage its adoption, while respecting the heterogeneity among the studies. PMID:24976965

Evidence shows that regular physical exercise reduces physiological reactivity to psychosocial stress. However, previous research mainly focused on the effect of endurance exercise, with only a few studies looking at the effect of resistance exercise. The current study tested whether individuals who regularly participate in either endurance or resistance training differ from untrained individuals in adrenal and cardiovascular reactivity to psychosocial stress. Twelve endurance-trained men, 10 resistance-trained men, and 12 healthy but untrained men were exposed to a standardized psychosocial stressor, the Trier Social Stress Test. Measurements of heart rate, free salivary cortisol levels, and mood were obtained throughout the test and compared among the three groups. Overall, both endurance- and resistance-trained men had lower heart rate levels than untrained men, indicating higher cardiac performance of the trained groups. Trained men also exhibited lower heart rate responses to psychosocial stress compared with untrained men. There were no significant group differences in either cortisol responses or mood responses to the stressor. The heart rate results are consistent with previous studies indicating reduced cardiovascular reactivity to psychosocial stress in trained individuals. These findings suggest that long-term endurance and resistance trainings may be related to the same cardiovascular benefits, without exhibiting strong effects on the cortisol reactivity to stress.

Background: Evidence supports the use of pricing interventions in achieving healthier behaviour at population level. The public acceptability of this strategy continues to be debated throughout Europe, Australasia and USA. We examined public attitudes towards, and beliefs about the acceptability of pricing policies to change health-related behaviours in the UK. The study explores what underlies ideas of acceptability, and in particular those values and beliefs that potentially compete with the evidence presented by policy-makers. Methods: Twelve focus group discussions were held in the London area using a common protocol with visual and textual stimuli. Over 300 000 words of verbatim transcript were inductively coded and analyzed, and themes extracted using a constant comparative method. Results: Attitudes towards pricing policies to change three behaviours (smoking, and excessive consumption of alcohol and food) to improve health outcomes, were unfavourable and acceptability was low. Three sets of beliefs appeared to underpin these attitudes: (i) pricing makes no difference to behaviour; (ii) government raises prices to generate income, not to achieve healthier behaviour and (iii) government is not trustworthy. These beliefs were evident in discussions of all types of health-related behaviour. Conclusions: The low acceptability of pricing interventions to achieve healthier behaviours in populations was linked among these responders to a set of beliefs indicating low trust in government. Acceptability might be increased if evidence regarding effectiveness came from trusted sources seen as independent of government and was supported by public involvement and hypothecated taxation.

To investigate the concept of clinical governance being advocated by primary care groups/trusts (PCG/Ts), approaches being used to implement clinical governance, and potential barriers to its successful implementation in primary care. Qualitative case studies using semi-structured interviews and documentation review. Twelve purposively sampled PCG/Ts in England. Fifty senior staff including chief executives, clinical governance leads, mental health leads, and lay board members. Participants' perceptions of the role of clinical governance in PCG/Ts. PCG/Ts recognise that the successful implementation of clinical governance in general practice will require cultural as well as organisational changes, and the support of practices. They are focusing their energies on supporting practices and getting them involved in quality improvement activities. These activities include, but move beyond, conventional approaches to quality assessment (audit, incentives) to incorporate approaches which emphasise corporate and shared learning. PCG/Ts are also engaged in setting up systems for monitoring quality and for dealing with poor performance. Barriers include structural barriers (weak contractual levers to influence general practices), resource barriers (perceived lack of staff or money), and cultural barriers (suspicion by practice staff or problems overcoming the perceived blame culture associated with quality assessment). PCG/Ts are focusing on setting up systems for implementing clinical governance which seek to emphasise developmental and supportive approaches which will engage health professionals. Progress is intentionally incremental but formidable challenges lie ahead, not least reconciling the dual role of supporting practices while monitoring (and dealing with poor) performance.

To investigate young people's attitudes to, and understanding of, physical activity on glycaemic control in Type 1 Diabetes Mellitus. Four focus groups with 11-14 and 15-16 year olds were conducted with twelve young people with Type 1 Diabetes, from within a larger study investigating physical activity and fitness. Qualitative analysis of the focus group data was performed using Interpretative Phenomenological Analysis. Four superordinate themes were identified: Benefits of Exercise, Knowledge and Understanding, Information and Training and "You can do anything". Young people felt that exercising helped them to manage their diabetes and had a beneficial psychological and physical impact on their bodies. They reported a lack of knowledge and understanding about diabetes among school staff and other young people. The overwhelming sense from young people was that although diabetes impacts upon their lives, with preparation, physical activity can take place as normal. Whilst young people had an awareness of the physical and psychological benefits of exercise in managing their diabetes, they experienced difficulties at school. Professional support and discussions with young people, giving tailored strategies for managing Type 1 Diabetes during exercise are needed. Healthcare teams should ensure that the support and educational needs of school staff are met. Providing more opportunities to empower young people to take on the responsibility for their Type 1 Diabetes care is merited. Young people felt diabetes did not stop them from participating in activities; it is simply a part of them that needs managing throughout life.

Objective The aim of the study was to examine the effectiveness of an intensive inpatient three-week multimodal therapy. We focused especially on the impact on the multimodal therapy outcome of the pre-admission number of treatment types patients had received and of medical specialist groups patients had consulted. Methods 155 patients with chronic low back pain and indication for multimodal therapy were evaluated with respect to pain intensity, depression, anxiety, well-being, and pre-admission health care utilization. In our controlled clinical trial we compared N = 66 patients on the waiting list with N = 89 patients who received immediate treatment. The waiting list patients likewise attended multimodal therapy after the waiting period. Longitudinal post-treatment data for both were collected at three- and twelve-month follow-ups. The impact of pre-admission health care utilization on multimodal therapy outcome (post) was analysed by structural equation model. Results Compared to the control group, multimodal therapy patients’ pain intensity and psychological variables were significantly reduced. Longitudinal effects with respect to pre-measures were significant at three-month follow-up for pain intensity (ES = -0.48), well-being (ES = 0.78), anxiety (ES = -0.33), and depression (ES = -0.30). Effect sizes at twelve-month follow-up were small for anxiety (ES = -0.22), and moderate for general well-being (ES = 0.61). Structural equation model revealed that a higher number of pre-admission treatment types was associated with poorer post-treatment outcomes in pain intensity, well-being, and depression. Conclusion Multimodal therapy proved to be effective with regard to improvements in pain intensity, depression, anxiety, and well-being. The association between treatment effect and number of pre-admission pain treatment types suggests that patients would benefit more from attending multimodal therapy in an earlier stage of health care.

After Piketty?

PubMed

Atkinson, A B

2014-12-01

In this paper, I take Capital in the Twenty-First Century by Thomas Piketty as the starting point for a set of twelve policy proposals that could bring about a genuine shift in the distribution of income towards less inequality. In designing the set of proposals, I draw on the experience of reducing inequality in postwar Europe and on an analysis as to how the economic circumstances are now different in the twenty-first century, highlighting the role of technical change and the rise in capital emphasized by Piketty. The proposed measures span many fields of policy, and are not confined to fiscal redistribution, encompassing science policy, competition policy, public employment, a guaranteed return on small savings, a capital endowment, as well as more progressive taxation of income and wealth transfers, and a participation income. Inequality is embedded in our social structure, and the search for a significant reduction requires us to examine all aspects of our society. I focus on inequality within countries, and what can be achieved by national governments, with the UK specifically in mind. The primary audience is those concerned with policy-making in national governments, but implementation should not be seen purely in these terms. There are different levels of government, and certain proposals, particularly those concerned with taxation, may only be feasible if pursued by a group of countries in collaboration. The last of the twelve proposals - for a basic income for children - is specifically directed at the European Union. Finally, actions by individuals as consumers, as workers, or as employers, can all contribute to reducing inequality. © London School of Economics and Political Science 2014.

Functional jejunal interposition (FJI) has been applied as a reconstruction procedure to maintain the jejunal continuity and duodenal food passage after total gastrectomy in patients with gastric cancer. The purpose of this study was to evaluate clinical efficacy of the FJI procedure by comparing the functional outcomes of FJI to Roux-en-Y after total gastrectomy in gastric cancer patients, and investigate physiologic mechanisms by which FJI exerts beneficial outcomes in beagles. Patients with stage I-IV gastric cancer without metastasis and recurrence one year after surgery were enrolled in this retrospective study. Seventy one patients received FJI and seventy nine patients received Roux-en-Y after total gastrectomy. We evaluated the nutritional status at three and twelve months and incidence of complications up to twelve months after surgery. Beagles receiving sham operation, FJI, or Roux-en-Y after total gastrectomy were sacrificed forty eight hours postoperatively. Beagles were gavaged with active carbon for evaluating the intestinal transit rate. Intestinal tissues from the duodenojejunal anastomosis were collected for examining interstitial cells of Cajal (ICC), inflammation, and apoptosis. Compared to the bodyweight before surgery, the bodyweight loss at three and twelve months after surgery in patients receiving FJI was significant less than that in patients with Roux-en-Y. Patients with the FJI procedure showed significant increase of blood hemoglobin and total protein, compared to those at one month after surgery, and the prognostic nutrition index scores at three and twelve months after surgery. The incidence rates of post-operative complications, including reflux esophagitis, dumping syndrome, and Roux-en-Y syndrome were decreased in patients with FJI. Compared to beagles receiving Roux-en-Y, more ICC in the intestinal submuocsa, less intestinal epithelial cell apoptosis, and decreased inflammation in serosal side of the intestine were found in the FJI group. The intestinal transit rate in FJI group was lower than that in Roux-en Y group, indicating that FJI benefits food storage. The FJI procedure promotes nutritional recovery and decreases post-operative complications in gastric cancer patients after total gastrectomy, which may be through ameliorating intestinal inflammation and damage and reducing ICC loss to preserve food reservoir function and intestinal motility.

A group of Populus trichocarpa DUF231 proteins exhibit differential O-acetyltransferase activities toward xylan.

Wood represents the most abundant biomass produced by plants and one of its major components is acetyl xylan. Acetylation in xylan can occur at O-2 or O-3 of a xylosyl residue, at both O-2 and O-3 of a xylosyl residue, and at O-3 of a xylosyl residue substituted at O-2 with glucuronic acid. Acetyltransferases responsible for the regiospecific acetylation of xylan in tree species have not yet been characterized. Here we report the biochemical characterization of twelve Populus trichocarpa DUF231-containing proteins, named PtrXOATs, for their roles in the regiospecific acetylation of xylan. The PtrXOAT genes were found to be differentially expressed in Populus organs and among them, PtrXOAT1, PtrXOAT2, PtrXOAT9 and PtrXOAT10 exhibited the highest level of expression in stems undergoing wood formation. Activity assays of recombinant proteins demonstrated that all twelve PtrXOAT proteins were able to transfer acetyl groups from acetyl CoA onto a xylohexaose acceptor with PtrXOAT1, PtrXOAT2, PtrXOAT3, PtrXOAT11 and PtrXOAT12 having the highest activity. Structural analysis of the PtrXOAT-catalyzed reaction products using 1H NMR spectroscopy revealed that PtrXOAT1, PtrXAOT2 and PtrXOAT3 mediated 2-O- and 3-O-monoacetylation and 2,3-di-O-acetylation of xylosyl residues and PtrXOAT11 and PtrXOAT12 only catalyzed 2-O- and 3-O-monoacetylation of xylosyl residues. Of the twelve PtrXOATs, only PtrXOAT9 and PtrXOAT10 were capable of transferring acetyl groups onto the O-3 position of 2-O-glucuronic acid-substituted xylosyl residues. Furthermore, when expressed in the Arabidopsis eskimo1 mutant, PtrXOAT1, PtrXAOT2 and PtrXOAT3 were able to rescue the defects in xylan acetylation. Together, these results demonstrate that the twelve PtrXOATs are acetyltransferases with different roles in xylan acetylation in P. trichocarpa.

Manipulation under anesthesia has been reported to improve range of motion when other rehabilitative efforts fail to obtain adequate motion after total knee arthroplasty. The purpose of this study was to evaluate the effects of the timing of the manipulation on knee range of motion and clinical outcomes. All 2128 total knee arthroplasties performed at our institution from 2005 to 2011 were reviewed to determine the number of patients who had undergone manipulation under anesthesia. A total of 144 manipulations in eighty-eight women and forty-five men were reviewed. Manipulations under anesthesia that were performed within the first twelve weeks after total knee arthroplasty were considered early and those after that period were considered late. Patients were further substratified according to the timing of the manipulation: Group I included those who had the manipulation within six weeks; Group II, at seven to twelve weeks; Group III, at thirteen to twenty-six weeks; and Group IV, after twenty-six weeks. Outcomes evaluated included gains in flexion and final range of motion, and Knee Society objective and function scores between early and late manipulation, using various adjusted multivariable regression models and at a mean follow-up of fifty-one months (range, twelve to eighty-one months). Mediation analysis was used to investigate whether gains in range of motion from the manipulations under anesthesia alone had mediated the effect between the timing of the manipulation and the clinical outcomes. Patients who underwent early manipulation had a significantly higher mean gain in flexion (36.5° versus 17°), higher final range of motion (119° versus 95°), and higher Knee Society objective (89 versus 84 points) and function scores (88 versus 83 points) than those who had late manipulation under anesthesia. There were no significant differences in the outcomes of Groups I and II. Manipulations after twenty-six weeks resulted in unsatisfactory clinical outcomes. Multivariable regression analyses confirmed significantly better clinical outcomes with early manipulation. Mediation analysis showed that the timing of manipulation independently had significantly contributed to the outcomes. Orthopaedic surgeons should have a low threshold for performing early manipulations with the patient under anesthesia within twelve weeks after an arthroplasty, to achieve higher knee range of motion and improved clinical outcomes.

The objective of this double-blind clinical study, conducted in harmony with Volpe-Manhold design for studies of dental calculus, was to compare the efficacy of a dentifrice containing 0.3% triclosan/2.0% polyvinylmethyl ether/maleic acid (PVM/MA) copolymer/0.243% sodium fluoride in a 17% dual silica base (Colgate Total Advanced Toothpaste) to that of a commercially available dentifrice containing 0.243% sodium fluoride in a silica base (Crest Cavity Protection Toothpaste) with respect to the reduction of supragingival calculus formation. Adult male and female subjects from the San Francisco area were entered into the eight-week pre-test phase of the study. Subjects received an evaluation of oral soft and hard tissues and were given a complete oral prophylaxis. They were provided with a non-tartar control placebo dentifrice and a soft-bristled adult toothbrush, and were instructed to brush their teeth twice daily (morning and evening) for one minute. After eight weeks of using the placebo dentifrice, subjects were examined for baseline supragingival calculus formation using the Volpe-Manhold Calculus Index. Qualifying subjects were randomized into two treatment groups which were balanced for gender and baseline calculus scores. All subjects entered into the twelve-week test phase were given a complete oral prophylaxis, and were provided with their assigned dentifrice and a soft-bristled adult toothbrush for home use. Subjects were instructed to brush their teeth for one minute twice daily (in the morning and evening). Prior to each study visit, subjects refrained from brushing their teeth and eating and drinking for four hours. Seventy-seven (77) subjects complied with the protocol and completed the study. At the twelve-week examination, the Test Dentifrice group presented a mean Volpe-Manhold Calculus Index score of 13.22 and the Control Dentifrice group presented a score of 20.29. After twelve weeks of product use, the Test Dentifrice group exhibited 34.8% less supragingival calculus formation than the Control Dentifrice group (statistically significant at p < 0.05). The overall results of this double-blind clinical study support the conclusion that after twelve weeks' use of a dentifrice containing 0.3% triclosan/2.0% PVM/MA copolymer/0.243% sodium fluoride in a 17% dual silica base provides significantly greater control of supragingival calculus formation relative to that of a commercially available dentifrice containing 0.243% sodium fluoride in a silica base.

Present study evaluated the efficacy of natural derivative irrigants, Morinda citrifolia juice (MCJ), Aloe Vera and Propolis in comparison to 1% sodium hypochlorite with passive ultrasonic irrigation for removal of the intraradicular E. faecalis biofilms in extracted single rooted human permanent teeth. Biofilms of E. faecalis were grown on the prepared root canal walls of 60 standardized root halves which were longitudinally sectioned. These root halves were re-approximated and the samples were divided into five groups of twelve each. The groups were, Group A (1% NaOCl), Group B (MCJ), Group C (Aloe vera), Group D (Propolis) and Group E (Saline). These groups were treated with passive ultrasonic irrigation (PUI) along with the respective irrigants. The root halves were processed for scanning electron microscopy. Three images (X2.5), coronal, middle and apical, were taken for the twelve root halves in each of the five groups. The images were randomized and biofilm coverage assessed independently by three calibrated examiners, using a four-point scoring system. 1% NaOCl with passive ultrasonic irrigation (PUI) was effective in completely removing E. faecalis biofilm and was superior to the natural irrigants like MCJ, Aloe vera and Propolis tested in this study. 1% NaOCl used along with passive ultrasonic irrigation was effective in completely removing E. faecalis biofilm when compared to natural irrigants (MCJ, Aloe Vera and Propolis).

Birth preparedness and complication readiness (BP/CR) strategies are aimed at reducing delays in seeking, reaching, and receiving care. Counselling on birth preparedness is provided during antenatal care visits. However, it is not clear why birth preparedness messages do not translate to utilisation of facility delivery. This study explores the perceptions, experiences, and challenges the community faces on BP/CR. A qualitative study design using Focused Group Discussions was conducted. Twelve focus group discussions were held with four separate groups: young men and women and older men and women in a rural community in Tanzania. Qualitative content analysis was used to analyse the data. The community members expressed a perceived need to prepare for childbirth. They were aware of the importance to attend the antenatal clinics, relied on family support for practical and financial preparations such as saving money for costs related to delivery, moving closer to the nearest hospital, and also to use traditional herbs, in favour of a positive outcome. Community recognised that pregnancy and childbirth complications are preferably treated at hospital. Facility delivery was preferred; however, certain factors including stigma on unmarried women and transportation were identified as hindering birth preparedness and hence utilisation of skilled care. Challenges were related to the consequences of poverty, though the maternal health care should be free, they perceived difficulties due to informal user fees. This study revealed community perceptions that were in favour of using skilled care in BP/CR. However, issues related to inability to prepare in advance hinder the realisation of the intention to use skilled care. It is important to innovate how the community reinforces BP/CR, such as using insurance schemes, using community health funds, and providing information on other birth preparedness messages via community health workers.

Paediatric chronic fatigue syndrome (CFS)/myalgic encephalomyelitis (ME) is relatively common and disabling. Research is hampered because current patient-reported outcome measures (PROMs) do not capture outcomes that are important to children with CFS/ME. The aim of this study was to explore the aspects of life and health outcomes that matter to children with CFS/ME. Twenty-five children with CFS/ME were interviewed (11 males, 14 females; mean age 12.9 years (SD 2.2), range 8-17). Twelve were trial participants interviewed during the trial and 13 were recruited as part of a follow-up qualitative study. Parents were present in 19 interviews with their children. Three mothers participated in a focus group. All the interviews and the focus group were audio-recorded and transcribed. Data were analysed thematically using techniques of constant comparison. NVivo was used to structure and categorise data in a systematic way. Children identified four key themes (health outcome domains): 'symptoms' that fluctuated, which caused an unpredictable reduction in both 'physical activity' and 'social participation' all of which impacted on 'emotional well-being'. These domains were influenced by both 'management' and 'contextual factors', which could be positive and negative. The relationship between healthcare and school was considered pivotal. Children's descriptions helped to inform a conceptual model that is necessary to develop a new paediatric CFS/ME PROM. Doctors need to be aware of how children conceptualise CFS/ME; the relationship between healthcare and school is fundamental to ameliorate the impact of CFS/ME. ISRCTN81456207.

To develop a descriptive system for a glaucoma-specific preference-based health-related quality of life (HRQoL) instrument: the Health Utility for Glaucoma (HUG-5). The descriptive system was developed in two stages: item identification and item selection. A systematic literature review of HRQoL assessment of glaucoma was conducted using a comprehensive search strategy. Purposeful sampling was used to recruit patients with different clinical characteristics. Relevant items were presented to glaucoma patients through face-to-face, semi-structured interviews. Framework methodology was applied to analyze interview content. The recurring themes identified through an iterative content analysis represented topics of most importance and relevance to patients. These themes formed the domains of the HUG-5 descriptive system. Three versions of the descriptive system, differing in explanatory detail, were pilot tested using a focus group. The literature review identified 19 articles which contained 266 items. These items were included for the full text review and were used to develop an interview guide. From twelve patient interviews, 22 themes were identified and grouped into five domains that informed the five questions of the descriptive system. The HUG-5 measures visual discomfort, mobility, daily life activities, emotional well-being, and social activities. Each question has five response levels that range from "no problem" to "severe problem". The focus group comprised of seven additional patients unanimously preferred the version that contained detailed, specific examples to support each question. A 5-domain descriptive system of a glaucoma-specific preference-based instrument, the HUG-5, was developed and remains to be evaluated for validity and reliability in the glaucoma patient population.

Fermionic spin liquid analysis of the paramagnetic state in volborthite

Recently, thermal Hall effect has been observed in the paramagnetic state of volborthite, which consists of distorted kagome layers with S =1 /2 local moments. Despite the appearance of magnetic order below 1 K , the response to external magnetic field and unusual properties of the paramagnetic state above 1 K suggest possible realization of exotic quantum phases. Motivated by these discoveries, we investigate possible spin liquid phases with fermionic spinon excitations in a nonsymmorphic version of the kagome lattice, which belongs to the two-dimensional crystallographic group p 2 g g . This nonsymmorphic structure is consistent with the spin model obtained in the density functional theory calculation. Using projective symmetry group analysis and fermionic parton mean field theory, we identify twelve distinct Z2 spin liquid states, four of which are found to have correspondence in the eight Schwinger boson spin liquid states we classified earlier. We focus on the four fermionic states with bosonic counterpart and find that the spectrum of their corresponding root U (1 ) states features spinon Fermi surface. The existence of spinon Fermi surface in candidate spin liquid states may offer a possible explanation of the finite thermal Hall conductivity observed in volborthite.

To culturally adapt and evaluate the psychometric properties of the Young Children's Participation and Environment Measure (YC-PEM) for use by caregivers of Swedish children with and without disabilities, aged 2-5 years. Thirteen cognitive interviews and two focus groups with caregivers of children with and without disabilities were conducted to evaluate the cultural relevance of YC-PEM content for use in Sweden. Per participant feedback, a revised version of the Swedish YC-PEM was created and pilot tested with caregivers of children with disabilities (n = 11) and children with typical development (n = 22). User feedback informed content revisions to 7% of items. Internal consistency estimates of the Swedish YC-PEM pilot version were acceptable and ranged from .70 to .92 for all but two of the YC-PEM scales. Mean percentage agreement between raters ranged from 47% to 93% across YC-PEM scales for inter-rater, and 44% to 86% for test-retest. One of twelve YC-PEM scales revealed significant group differences between young children with and without disabilities. This study contributes preliminary evidence for the use of some scales within a culturally adapted YC-PEM in Sweden. Further validation with larger samples will allow for parametric testing to evaluate its psychometric properties.

Cerebral hemovelocity reveals differential resource allocation strategies for extraverts and introverts during vigilance.

Extraversion--one of the Big 5 personality factors--correlates negatively with vigilance, but most studies focus on performance outcomes and not the performance process. Previous research has shown that transcranial Doppler sonography (TCD), which measures cerebral blood flow velocity (CBFV), can be used to examine resource allocation strategies during vigilance performance. Hence, this study was designed to assess the attentional resource allocation strategies of introverts and extraverts using the CBFV measure. Twelve extroverts and 13 introverts monitored a 60-min vigilance task for a critical signal--the absence of a line on a five-circle array. The results revealed an overall performance decrement that was not modulated by extraversion. We observed an interaction between extraversion and time; CBFV declined in the introversion group, but not in the extraversion group. Additionally, an interaction between cerebral hemisphere and personality revealed that extraverts were recruiting resources from both the left and right cerebral hemispheres, while introverts only recruited resources from the right hemisphere. The results suggest that extraverts can allocate compensatory effort to mask performance differences. We discuss the theoretical and practical implications of these findings and offer future research directions that may help us understand these effects.

To observe the combined effects of astragalus soup and persistent Taiji boxing on improving the immunity of women of advanced years. 120 elderly women lacking daily exercise were chosen as the study subjects. By using the table of random numbers, they were then divided into the control group and the experiment group, consisting of 60 each. The control group practiced Taiji boxing for 45 minutes twice a day. The experiment group did the same, and, in addition, took astragalus soup after each boxing. Indexes related to physical immunity of the two groups were observed and compared when they were first chosen, when the alternative treatment was applied three, six and twelve months later, respectively. The two groups demonstrated no significant differences in general data and research indexes when chosen (P > 0.05). Three months after the two groups were chosen and treated differently, the control group demonstrated no significant improvement while most indexes of the experiment group improved considerably (P > 0.05). After six months, the related indexes of both groups improved substantially (P < 0.05) and the improvement with the experiment was even clearer (P < 0.05). Twelve months later, the improvement with the experiment group was more noticeable (P < 0.01 or P < 0.05). In a relatively short period of three months, Taiji boxing produces no noticeable effect on the improvement of immunity in elderly women. However, when they resume the exercise for another three months and longer, Taiji boxing has a noticeable advantage and the effect is the most favorable when it is combined with astragalus soup.

Twelve-step programs have stressed the importance of spiritual practices for over four decades. The spiritual principles embodied in the twelve-step programs may be key in their success of recovering addicts/alcoholics with an overall recovery rate of 34%. A literature search revealed little available data on spiritual principles and practices and their effects on long-term recovery from substance abuse. This study compared two groups of recovering addicts, those with one year of recovery and those with less than one year and a history of relapse. Spiritual practices were measured using a five-point Likert scale questionnaire. The results of the study indicated a relationship between spiritual practices and long-term recovery from substance abuse.

Decreasing internal focus of attention improves postural control during quiet standing in young healthy adults.

PubMed

Nafati, Gilel; Vuillerme, Nicolas

2011-12-01

This experiment was designed to investigate whether and how decreasing the amount of attentional focus invested in postural control could affect bipedal postural control. Twelve participants were asked to stand upright as immobile as possible on a force platform in one control condition and one cognitive condition. In the latter condition, they performed a short-term digit-span memory task. Decreased center-of-gravity displacements and decreased center-of-foot-pressure displacements minus center-of-gravity displacements were observed in the cognitive condition relative to the control condition. These results suggest that shifting the attentional focus away from postural control by executing a concurrent attention-demanding task could increase postural performance and postural efficiency.

Objectives: To investigate the relation between occlusal loading and peri-implant clinical parameters (probing depth, bleeding on probing, gingival retraction, width of keratinized mucosa, and crevicular fluid volume) in patients with implant-supported complete fixed prostheses in both arches. Material and Methods: This clinical study took place at the University of Valencia (Spain) dental clinic. It included patients attending the clinic for regular check-ups during at least 12 months after rehabilitation of both arches with implant-supported complete fixed ceramo-metallic prostheses. One study implant and one control implant were established for each patient using the T-Scan®III computerized system (Tesco, South Boston, USA). The maxillary implant closest to the point of maximum occlusal loading was taken as the study implant and the farthest (with least loading) as the control. Occlusal forces were registered with the T-Scan® III and then occlusal adjustment was performed to distribute occlusal forces correctly. Peri-implant clinical parameters were analyzed in both implants before and two and twelve months after occlusal adjustment. Results: Before occlusal adjustment, study group implants presented a higher mean volume of crevicular fluid (51.3±7.4 UP) than the control group (25.8±5.5 UP), with statistically significant difference. Two months after occlusal adjustment, there were no significant differences between groups (24.6±3.8 UP and 26±4.5 UP respectively) (p=0.977). After twelve months, no significant differences were found between groups (24.4±11.1 UP and 22.5±8.9 UP respectively) (p=0.323). For the other clinical parameters, no significant differences were identified between study and control implants at any of the study times (p>0.05). Conclusions: Study group implants receiving higher occlusal loading presented significantly higher volumes of crevicular fluid than control implants. Crevicular fluid volumes were similar in both groups two and twelve months after occlusal adjustment. Key words:Occlusal loading, crevicular fluid, peri-implant clinical parameters, T-Scan®.

Three focus groups were conducted with residential construction workers from local New Jersey labor organizations to characterize barriers to fall protection use among residential construction contractors who work for companies with fewer than ten employees. Thirty-six residential construction workers volunteered to participate, the average age was thirty-nine years, and twenty-four (67%) were of Hispanic origin. Twelve (33%) of the participants reported having fallen from greater than 6 ft at work and twenty (56%) of the participants had known someone who has fallen from greater than 6 ft. Sixteen (44%) had not been provided with fall protection equipment by their employer and eighteen (50%) reported their current employer had not provided workplace safety training. Factors that created barriers to use of fall protection equipment such as equipment availability, employee/employer relationships, cultural differences, and company size were identified. Results from this study confirm that falls remain a concern among residential construction workers in small companies. © The Author(s) 2015.

Decision support tools for the assessment and management of breast cancer risk may improve uptake of prevention strategies. End-user input in the design of such tools is critical to increase clinical use. Before developing such a computerized tool, we examined clinicians' practice and future needs. Twelve breast surgeons, 12 primary care physicians and 5 practice nurses participated in 4 focus groups. These were recorded, coded, and analyzed to identify key themes. Participants identified difficulties assessing risk, including a lack of available tools to standardize practice. Most expressed confidence identifying women at potentially high risk, but not moderate risk. Participants felt a tool could especially reassure young women at average risk. Desirable features included: evidence-based, accessible (e.g. web-based), and displaying absolute (not relative) risks in multiple formats. The potential to create anxiety was a concern. Development of future tools should address these issues to optimize translation of knowledge into clinical practice. Copyright © 2014 Elsevier Ltd. All rights reserved.

Photovoice is a research method developed to help communities share images as a tool for discussion of key issues. Although this may be useful to promote healthy behavior, using Photovoice in adolescents has been logistically challenging. Given adolescents’ engagement in social media, our study explored the feasibility of using a photo-sharing mobile phone application, Instagram, to accomplish the principles of Photovoice. Twenty adolescents 14 to 18 years old with type 1 diabetes were asked to use Instagram to post any diabetes-related photo for 3 weeks. Individual interviews and a focus group were also offered, and recruitment and retention statistics were tracked. Of those approached (n = 47), 43% agreed to participate. Twelve were actively engaged. Shared photos were most likely to fall into the categories of diabetes care, humor, or food. Engaged participants universally reported the project to be a positive experience; however, there were technological and personal factors to consider for widespread implementation. PMID:25904674

Photovoice is a research method developed to help communities share images as a tool for discussion of key issues. Although this may be useful to promote healthy behavior, using Photovoice in adolescents has been logistically challenging. Given adolescents' engagement in social media, our study explored the feasibility of using a photo-sharing mobile phone application, Instagram, to accomplish the principles of Photovoice. Twenty adolescents 14 to 18 years old with type 1 diabetes were asked to use Instagram to post any diabetes-related photo for 3 weeks. Individual interviews and a focus group were also offered, and recruitment and retention statistics were tracked. Of those approached (n = 47), 43% agreed to participate. Twelve were actively engaged. Shared photos were most likely to fall into the categories of diabetes care, humor, or food.

"Stories Take Your Role Away From You": Understanding the Impact on Health Care Professionals of Viewing Digital Stories of Pediatric and Adolescent/Young Adult Oncology Patients.

PubMed

Laing, Catherine M; Moules, Nancy J; Estefan, Andrew; Lang, Mike

The purpose of this philosophical hermeneutic study was to understand the effects on health care providers (HCPs) of watching digital stories made by (past and present) pediatric and adolescent/young adult (AYA) oncology patients. Twelve HCPs participated in a focus group where they watched digital stories made by pediatric/AYA oncology patients and participated in a discussion related to the impact the stories had on them personally and professionally. Findings from this research revealed that HCPs found digital stories to be powerful, therapeutic, and educational tools. Health care providers described uses for digital stories ranging from education of newly diagnosed families to training of new staff. Digital stories, we conclude, can be an efficient and effective way through which to understand the patient experience, implications from which can range from more efficient patient care delivery to decision making. Recommendations for incorporating digital storytelling into healthcare delivery are offered.

Fluticasone furoate/Vilanterol 92/22 μg once-a-day vs Beclomethasone dipropionate/Formoterol 100/6 μg b.I.D.: a 12-month comparison of outcomes in mild-to-moderate asthma.

Bronchial asthma is an inflammatory disease of the airways. Beclomethasone dipropionate/Formoterol (BDP/F) and Fluticasone furoate/Vilanterol (FF/V) are two of the most effective LABA/ICS combinations for managing persistent bronchial asthma. Aim of the study was to compare the outcomes achieved in mild-to-moderate asthma patients assuming BDP/F 100/6 μg b.i.d. (Group A) or FF/V 92/22 μg once-daily (Group B) for 12-months. No head-to-head long-term comparison is available at present. Data were automatically and anonymously obtained from the institutional database: FEV 1 % predicted values; the exacerbation and hospitalization rates; days of hospitalization; GP and/or specialist visits; days of inactivity; courses of systemic steroids and/or antibiotics were recorded at baseline and after 3, 6 and 12 months of both treatments. The overall adherence to treatments was also calculated. The propensity score method was used for matching and comparing the two cohorts of patients; Anova and Wilcoxon tests were used for checking the trends and time-to-time comparisons over the period; statistical significance was accepted for p  < 0.05. The PS-matching process returned a cohort of 40 group A patients matched with 40 patients of group B, fully comparable for demographics, clinical characteristics, and comorbidities. The improvement in lung function was significant in both groups ( p  < 0.001), even if it was significantly higher and time-dependent in group B. The mean (±SE) exacerbation rate/patient changed from 0.63 (±0.13) at baseline to 0.53 (±0.12) after three; to 0.58 (±0.13) after six, and to 0.60 (±0.18) after twelve months in group A (p = ns), while from of 1.05 (±0.16) at baseline, to 0.28 (±0.07) after three; to 0.33 (±0.08) after six, and to 0.18 (±0.08) after twelve months in group B ( p  < 0.001), respectively. The mean hospitalization rate/patient changed from 0.25 ± 0.07 at baseline to 0.15 (±0.06) after three; to 0.08 (±0.04) after six, and to 0.13 (±0.05) after twelve months in group A (p = ns), while from 0.30 (±0.07) at baseline to 0.08 (±0.04) after three; to 0.10 (±0.05) after six, and to 0.03 (±0.03) after twelve months in group B ( p  < 0.001), respectively. Also mean duration of hospitalization and days of inactivity were in favour of FF/V treatment over time (in both cases p  < 0.001). GP's visits were reduced by both treatments ( p  < 0.007 in group A and p < 0.001 in group B, respectively, while Specialist's visits only dropped during FF/V ( p  < 0.001). Steroid and antibiotic courses were significantly reduced by both treatments, even if more systematically in group B (p < 0.001 vs p  < 0.007, and p < 0.001 vs p  < 0.044, respectively). Moreover, changes in all outcomes considered proved time-dependent during the FF/V treatment only, particularly over the second semester. Finally, the overtime adherence to treatment was higher by 22 days during FF/V . Both the ICS/LABA combinations proved effective, even if characterized by different patterns of effectiveness either in terms of lung function and of long-term clinical outcomes. Only the once-daily inhalation of combined FF/V 92/22 μg once-daily optimized systematically the exacerbation and hospitalization rates in mild-to-moderate asthma, together with all other outcomes over time. The effectiveness of FF/V 92/22 once-daily μg proved progressive and time-dependent over the twelve-month period of the study, and associated to a higher adherence to treatment.

To correlate cloned nuclear DNA sequences with previously characterized mutations in Chlamydomonas and, to gain insight into the organization of its nuclear genome, we have begun to map molecular markers using restriction fragment length polymorphisms (RFLPs). A Chlamydomonas reinhardtii strain (CC-29) containing phenotypic markers on nine of the 19 linkage groups was crossed to the interfertile species Chlamydomonas smithii. DNA from each member of 22 randomly selected tetrads was analyzed for the segregation of RFLPs associated with cloned genes detected by hybridization with radioactive DNA probes. The current set of markers allows the detection of linkage to new molecular markers over approximately 54% of the existing genetic map. This study focused on mapping cloned flagellar genes and genes whose transcripts accumulate after deflagellation. Twelve different molecular clones have been assigned to seven linkage groups. The α-1 tubulin gene maps to linkage group III and is linked to the genomic sequence homologous to pcf6-100, a cDNA clone whose corresponding transcript accumulates after deflagellation. The α-2 tubulin gene maps to linkage group IV. The two β-tubulin genes are linked, with the β-1 gene being approximately 12 cM more distal from the centromere than the β-2 gene. A clone corresponding to a 73-kD dynein protein maps to the opposite arm of the same linkage group. The gene corresponding to the cDNA clone pcf6-187, whose mRNA accumulates after deflagellation, maps very close to the tightly linked pf-26 and pf-1 mutations on linkage group V. PMID:2906025

To report on the long-term results of high-intensity focused ultrasound (HIFU) in the treatment of localized prostate cancer. Patients with clinical Stage T1c-T3N0M0, biopsy proven, localized prostate cancer, with a serum prostate specific antigen (PSA) level of <30 ng/ml, any Gleason score were included. All patients underwent HIFU using the Sonablate™ (S) device and were required to have a minimal follow-up of 2 years after the last HIFU session to be included in this analysis. Four different generation HIFU devices, S200, S500, S500 version 4 and S500 TCM, have been used for this study. Biochemical failure was defined according to the Phoenix definition (PSA nadir+2ng/ml). Seven hundred and fifty-three men with prostate cancer were included. The patients were divided into two groups: in the Former group, 421 patients were treated with S200 and 500 from 1990 to 2005; in the Latter group, 332 patients were treated with S500 ver. 4 and TCM from 2005 to 2009. The mean age, PSA, Gleason score, operation time, and follow-up period in the Former and Latter groups were 68 and 67 years, 11.3 and 9.7 ng/ml, 6.2 and 6.6, 167 and 101 min, and 49 and 38 months, respectively. The biochemical disease-free rate (BDFR) in the groups at 5 years was, respectively, 67% and 53%, and was 50% at 10 years in the Former group (p<0.0001). The BDFR in patients in the low-, intermediate-, and high-risk groups in the Former group at 5 and 10 years were 68% and 65%, 52% and 48%, and 43% and 40%, respectively (p<0.0001). The BDFR in patients in the low-, intermediate-, and high-risk groups in the Latter group at 5 years were 83%, 76%, and 42% (p<0.0001). The negative prostate biopsy rate in the Former and Latter groups was 81% and 93%, respectively. Postoperative erectile dysfunction was noted in 45%, 38%, and 24% of patients at 6 months, 12 months, and 2 years after HIFU. The results after long-term follow-up have indicated that HIFU is an efficient and safe treatment for patients with localized prostate cancer, especially low-and intermediate-risk patients.

Purpose To identify macro level trends that are changing the needs of epidemiologic research and practice and to develop and disseminate a set of competencies and recommendations for epidemiologic training that will be responsive to these changing needs. Methods There were three stages to the project: 1) assembly of a working group of senior epidemiologists from multiple sectors, 2) Identifying relevant literature, and 3) conducting key informant interviews with 15 experienced epidemiologists. Results Twelve macro trends were identified along with associated actions for the field and educational competencies. The macro trends include: 1) “Big Data”/ informatics, 2) the changing health communication environment, 3) the Affordable Care Act/health care system reform, 4) shifting demographics, 5) globalization, 6) emerging high throughput technologies (“omics”), 7) a greater focus on accountability, 8) privacy changes, 9) a greater focus on “upstream” causes of disease, 10) the emergence of translational sciences, 11) the growing centrality of team and trans-disciplinary science, and 12) the evolving funding environment. Conclusion Addressing these issues through curricular change is needed to allow the field of epidemiology to more fully reach and sustain its full potential to benefit population health and remain a scientific discipline that makes critical contributions to ensuring clinical, social, and population health.

Clinical reasoning is a crucial component of training in health professions. These cognitive skills are necessary to provide quality care and avoid diagnostic error. Much previous literature has focused on teaching clinical reasoning in nonclinical environments and does not include learner reflections. The authors sought to explore, through multiple perspectives including learners, techniques used by exemplary inpatient clinician-educators for explicitly cultivating clinical reasoning. The authors conducted (2014-2015) a multisite, exploratory qualitative study examining how excellent clinician-educators foster clinical reasoning during general medicine rounds. This was accomplished through interviews of educators, focus group discussions with learners, and direct observations of clinical teaching. The authors reviewed field notes and transcripts using techniques of thematic analysis. Twelve clinician-educators, 57 current learners, and 26 former learners participated in observations and interviews. The techniques and behaviors of educators were categorized into 4 themes, including 1) emphasizing organization and prioritization, 2) accessing prior knowledge, 3) thinking aloud, and 4) analyzing the literature. The findings of this comprehensive study both confirm strategies found in previous literature and provide novel approaches. This is the first study to incorporate the perspectives of learners. Educators' techniques and behaviors, identified through direct observation and supported by reflections from the entire team, can inform best practices for the teaching of clinical reasoning.

Physicians need good communication skills to communicate effectively with patients. The objective of this review was to identify effective training strategies for teaching communication skills to qualified physicians. PubMED, PsycINFO, CINAHL, and COCHRANE were searched in October 2008 and in March 2009. Two authors independently selected relevant reviews and assessed their methodological quality with AMSTAR. Summary tables were constructed for data-synthesis, and results were linked to outcome measures. As a result, conclusions about the effectiveness of communication skills training strategies for physicians could be drawn. Twelve systematic reviews on communication skills training programmes for physicians were identified. Some focused on specific training strategies, whereas others emphasized a more general approach with mixed strategies. Training programmes were effective if they lasted for at least one day, were learner-centred, and focused on practising skills. The best training strategies within the programmes included role-play, feedback, and small group discussions. Training programmes should include active, practice-oriented strategies. Oral presentations on communication skills, modelling, and written information should only be used as supportive strategies. To be able to compare the effectiveness of training programmes more easily in the future, general agreement on outcome measures has to be established. Copyright © 2010 Elsevier Ireland Ltd.

The Indian River Lagoon, is part of the longest barrier island complex in the United States, is a region of particular concern to the environmental scientist because of the rapid rate of human development throughout the region and the geographical position in between the colder temperate zone and warmer sub-tropical zone. Thus, the surface water quality analysis in this region always brings the newer information. In this present study, multivariate statistical procedures were applied to analyze the spatial and temporal water quality in the Indian River Lagoon over the period 1998-2013. Twelve parameters have been analyzed on twelve key water monitoring stations in and beside the lagoon on monthly datasets (total of 27,648 observations). The dataset was treated using cluster analysis (CA), principle component analysis (PCA) and non-parametric trend analysis. The CA was used to cluster twelve monitoring stations into four groups, with stations on the similar surrounding characteristics being in the same group. The PCA was then applied to the similar groups to find the important water quality parameters. The principal components (PCs), PC1 to PC5 was considered based on the explained cumulative variances 75% to 85% in each cluster groups. Nutrient species (phosphorus and nitrogen), salinity, specific conductivity and erosion factors (TSS, Turbidity) were major variables involved in the construction of the PCs. Statistical significant positive or negative trends and the abrupt trend shift were detected applying Mann-Kendall trend test and Sequential Mann-Kendall (SQMK), for each individual stations for the important water quality parameters. Land use land cover change pattern, local anthropogenic activities and extreme climate such as drought might be associated with these trends. This study presents the multivariate statistical assessment in order to get better information about the quality of surface water. Thus, effective pollution control/management of the surface waters can be undertaken.

The impact of long work hours and shift work on cognitive errors in nurses.

Pilot study to examine the impact of long work hours and shift work on cognitive errors in nurses. Twelve-hour shifts are more commonly used in hospital settings and there is growing concern over the impact that extended and irregular work hours have on nurses' well-being and performance. Twenty-eight nurses working different shifts (8-hr days and 12-hr rotation) participated in this study. Nurses were assessed at the beginning of four consecutive shifts using actigraphy, a sleep diary and an after work questionnaire. Nurses working 12-hr rotations had less total sleep time and less sleep efficiency than 8-hr day nurses. Twelve-hour rotation nurses also napped more than their counterparts. There were no differences between the two groups with respect to cognitive errors. Twelve-hour rotations have a negative effect on nurses' sleep patterns. There is no evidence indicating 12-hr rotations increased errors. Nurse managers can implement specific strategies, such as greater shift work flexibility and designated quiet time, to reduce the effects of disturbed sleep patterns in nurses. © 2017 John Wiley & Sons Ltd.

While psychological care, including supportive group therapy, is a mainstay of burn treatment in the developed world, few reports of support groups for burn survivors and their caregivers in the developing world exist. This study records the findings of a support group in Malawi and provides a qualitative analysis of thematic content discussed by burn survivors and caregivers. We established a support group for burn survivors and caregivers from February-May 2012 in the burn unit at Kamuzu Central Hospital in Lilongwe, Malawi. Sessions were held weekly for twelve weeks and led by a Malawian counselor. The group leader compiled transcripts of each session and these transcripts were qualitatively analyzed for thematic information. Thematic analysis demonstrated a variety of psychological issues discussed by both survivors and caregivers. Caregivers discussed themes of guilt and self-blame for their children's injuries, worries about emotional distance now created between caregiver and survivor, fears that hospital admission meant likely patient death and concerns about their child's future and burn associated stigma. Burn survivors discussed frustration with long hospitalization courses, hope created through interactions with hospital staff, the association between mental and physical health, rumination about their injuries and how this would affect their future, decreased self-value, increased focus on their own mortality and family interpersonal difficulties. The establishment of a support group in our burn unit provided a venue for burn survivors and their families to discuss subjective experiences, as well as the dissemination of various coping techniques. Burn survivors and their caregivers in Malawi would benefit from the establishment of similar groups in the future to help address the psychological sequelae of burns.

Walthew, Patricia J

2004-09-01

This study investigated nurse educators' conceptions of critical thinking used in making judgment related to nursing. Twelve nurse educators from a large nursing school in an urban environment in New Zealand participated in this qualitative study. A semistructured questionnaire was used to explore the nurse educators' conceptions of critical thinking. The study found that the participants viewed rational, logical thinking as a central focus of critical thinking. However, in addition to these traditional perspectives, the nurse educators also included in their conceptions views more commonly held by feminist writers. These aspects focused on attention to intuition, subjective knowing, attention to context, emotions, and caring.

Care staff perspective on use of texture modified food in care home residents with dysphagia and dementia.

Dysphagia and dementia are conditions, which combined, can lead to complications for the person and require good nutritional care. There is very little evidence-based literature regarding nutritional care for people with dysphagia and dementia. It is clear that care staff plays a vital role, and that communication and informed decision-making are critical to the process, yet little is known regarding the use of available interventions such as texture modified food (TMF), and their acceptability and feasibility for care staff and residents. Therefore the aim of this study was to investigate the experiences of care staff when providing nutritional care for people with dysphagia and dementia, and their impressions and experience of using TMF as a new intervention for nutrition. This was a qualitative study with an inductive approach, which aimed to explore the experience of care staff using TMF in a care home setting. Data were collected using focus group interviews, an approach which is validated as a means of supporting and developing the understanding of a phenomenon, through interactions and discussions in the group. Participants were care staff working in a care home setting in Norway. Twelve participants were recruited to this study across two focus groups. The cohort included four nurses, six practical nurses, one nurse assistants and one student nurse. Four main categories emerged from the focus group discussions regarding the use of TMF. These were: (I) emotional strain; (II) deficient nutritional care; (III) increased self-efficacy with use of TMF; (IV) better nutritional care with TMF. Use of TMF to improve nutritional care for people with dysphagia appears to have merit for both residents and care staff, and should be considered as a means of improving nutritional care for people with dementia in care homes. Minimizing feeding difficulties and increasing nutritional intake is an important goal when caring for this vulnerable group of people, and there is a need to provide better training and support for care staff to ensure they feel confident and empowered to provide high quality nutritional care. The existing Norwegian Directorate of Health checklist for nutritional care may provide a helpful basis for improvements to guidance that accounts for the needs of staff and institutions. Further research and evaluation of an intervention for tailored nutritional care is warranted to improve this critical aspect of dementia care.

In Tanzania, more than 90% of all pregnant women attend antenatal care at least once and approximately 62% four times or more, yet less than five in ten receive skilled delivery care at available health units. We conducted a qualitative study in Ngorongoro district, Northern Tanzania, in order to gain an understanding of the health systems and socio-cultural factors underlying this divergent pattern of high use of antenatal services and low use of skilled delivery care. Specifically, the study examined beliefs and behaviors related to antenatal, labor, delivery and postnatal care among the Maasai and Watemi ethnic groups. The perspectives of health care providers and traditional birth attendants on childbirth and the factors determining where women deliver were also investigated. Twelve key informant interviews and fifteen focus group discussions were held with Maasai and Watemi women, traditional birth attendants, health care providers, and community members. Principles of the grounded theory approach were used to elicit and assess the various perspectives of each group of participants interviewed. The Maasai and Watemi women's preferences for a home birth and lack of planning for delivery are reinforced by the failure of health care providers to consistently communicate the importance of skilled delivery and immediate post-partum care for all women during routine antenatal visits. Husbands typically serve as gatekeepers of women's reproductive health in the two groups - including decisions about where they will deliver- yet they are rarely encouraged to attend antenatal sessions. While husbands are encouraged to participate in programs to prevent maternal-to-child transmission of HIV, messages about the importance of skilled delivery care for all women are not given emphasis. Increasing coverage of skilled delivery care and achieving the full implementation of Tanzania's Focused Antenatal Care Package in Ngorongoro depends upon improved training and monitoring of health care providers, and greater family participation in antenatal care visits.

Foot health education for people with rheumatoid arthritis: the practitioner's perspective

PubMed Central

2012-01-01

Background Patient education is considered to be a key role for podiatrists in the management of patients with rheumatoid arthritis (RA). Patient education has undoubtedly led to improved clinical outcomes, however no attempts have been made to optimise its content or delivery to maximise benefits within the context of the foot affected by rheumatoid arthritis. The aim of this study was to identify the nature and content of podiatrists' foot health education for people with RA. Any potential barriers to its provision were also explored. Methods A focus group was conducted. The audio dialogue was recorded digitally, transcribed verbatim and analysed using a structured, thematic approach. The full transcription was verified by the focus group as an accurate account of what was said. The thematic analysis framework was verified by members of the research team to ensure validity of the data. Results Twelve members (all female) of the north west Podiatry Clinical Effectiveness Group for Rheumatology participated. Six overarching themes emerged: (i) the essence of patient education; (ii) the content; (iii) patient-centred approach to content and timing; (iv) barriers to provision; (v) the therapeutic relationship; and (vi) tools of the trade. Conclusion The study identified aspects of patient education that this group of podiatrists consider most important in relation to its: content, timing, delivery and barriers to its provision. General disease and foot health information in relation to RA together with a potential prognosis for foot health, the role of the podiatrist in management of foot health, and appropriate self-management strategies were considered to be key aspects of content, delivered according to the needs of the individual. Barriers to foot health education provision, including financial constraints and difficulties in establishing effective therapeutic relationships, were viewed as factors that strongly influenced foot health education provision. These data will contribute to the development of a patient-centred, negotiated approach to the provision of foot health education for people with RA. PMID:22233879

In general, Japanese and Caucasians differ in their response to alcohol. To investigate these differences the alcohol clamping method can be used. This strictly controlled infusion regimen provides a reliable tool to study contrasts in central nervous system (CNS) effects and/or alcohol disposition. In this study, twelve Japanese and twelve Caucasian healthy volunteers received two concentrations of intravenous alcohol or placebo using the alcohol clamp. Infusion rates during the steady state phase were used to compare alcohol clearance between the subgroups. Central nervous system (CNS) effects were frequently measured throughout the clamp. On average, significantly lower amounts of alcohol were needed to maintain similar stable concentrations in the Japanese group. However, these differences disappeared when values were corrected for lean body mass. The most pronounced pharmacodynamic differences between the groups were observed on body sway and on the visual analogue scale for subjective alcohol effects, mainly at the highest dose level. The alcohol clamp seems a useful method to compare differences in alcohol metabolism between groups. Some CNS effects of alcohol differed clearly between Japanese and Caucasians, but others did not, even though alcohol levels were stable and similar between the two groups.

In order to study Staphylococcus epidermis and Staphylococcus aureus in vitro viability after the exposure to ultraviolet (UV) light and riboflavin, twelve strains of Staphylococcus epidermis and twelve strains of Staphylococcus aureus were isolated from patients with bacterial keratitis. The growth situation of Staphylococcus epidermidis and Staphylococcus aureus under different experimental conditions was qualitatively observed. The number of colonies surviving bacteria was counted under different UV light power and different exposure time. The experiment showed that there was no inhibition effect on the growth of bacteria using riboflavin alone. In UV alone group and UV-riboflavin group, inhibition effect on the bacteria growth was found. The UV-riboflavin combination had better inhibition effect on bacteria than UV irradiation alone. The amount of bacteria in the UV-riboflavin group was decreased by 99.1%~99.5% and 54.8%~64.6% in the UV alone group, when the UV light power was 10.052 mW/cm 2 and the irradiation time was 30 min. Moreover, with the increase of the UV power or irradiation time, the survival rates of bacteria were rapidly reduced. Compared with Staphylococcus aureus , Staphylococcus epidermis was more easily to be killed under the action of UV light combined with riboflavin.

To compare the kinematics of lower limb joints between individuals with and without chronic ankle instability (CAI) during cross-turn and -cutting movements. Cross-sectional study. Motion analysis laboratory. Twelve subjects with CAI and twelve healthy controls. Hip flexion, adduction, and internal rotation, knee flexion, and ankle dorsiflexion and inversion angles were calculated in the 200 ms before initial ground contact and from initial ground contact to toe-off (stance phase) in a cross-turn movement during gait and a cross-cutting movement from a forward jump, and compared across the two groups. In the cross-cutting movement, the CAI group exhibited greater hip and knee flexion than the control group during the stance phase, and more hip abduction during the period before initial contact and the stance phase. In the cross-turn movement the joint kinematics were similar in the two groups. CAI subjects exhibited an altered pattern of the proximal joint kinematics during a cross-cutting movement. It is important for clinicians to assess the function of the hip and knee as well as the ankle, and to incorporate coordination training for the entire lower limb into rehabilitation after lateral ankle sprains.

To assess the level of melanoma awareness and risk perception among ethnic minorities and to identify ways to enhance the relevance of melanoma educational materials for ethnic minorities.   Twelve focus groups composed of participants from a single ethnicity [African-American (n=40), Hispanic (n=40), and Asian (n=40)], participated in a 2 h discussion on melanoma and skin cancer and commented on an educational brochure by the American Cancer Society and reacted to photographs of melanoma on ethnic skin. Participants also evaluated the ability to sunburn and tan and the skin cancer risk of images of celebrities before and after the discussion. Additionally, participants assessed the skin tone of celebrities as very fair, fair, olive, light brown, dark brown, and very dark. The audiotape recordings of the 12 focus groups were transcribed and analyzed with the Non-numerical Unstructured Data Indexing Searching and Theorizing software for common themes. The common themes were (1) lack of relevance of skin cancer to ethnic people, (2) understanding of skin cancer risk terminology is based on personal experience and what is acquired from the media, and (3) sources of health information for ethnic minorities are fragmented and physicians are not the primary source of information. Celebrity images representing the six skin tones were selected. Relevance of melanoma education to ethnic people may be improved by using 'melanoma skin cancer', photographs of early melanoma in people with dark skin, and providing guidance on how to inspect hands and feet for suspicious moles.

To investigate the differences in acculturation experiences between parent and adolescent refugees from the Horn of Africa in Melbourne, Australia and to explore food beliefs and perceived health risks from an intergenerational perspective. Qualitative cross-sectional study involving a combination of semi-structured one-on-one interviews and focus group discussions. North-West suburbs of Melbourne, Australia. Eritrean, Ethiopian, Somali and Sudanese refugees. Using a purposeful sampling technique, twelve semi-structured face-to-face interviews (nine adults and three adolescents) and four in-depth focus groups (two with adolescents each containing six participants and two with adults one containing six participants and the other ten participants) were carried out. Thus overall data were obtained on fifteen adolescents and twenty-five parents. Qualitative analysis identified differences between parents and adolescents in relation to lifestyle, diet and physical activity. Views regarding health consequences of their changed diets also differed. Parental feeding practices encompassed a variety of methods and were enforced in an attempt by parents to control their children's dietary behaviours and prevent their drift away from traditional eating habits. These findings call for more research to contextualise dietary acculturation among refugee youth and the impact of migration on parenting styles and feeding practices in communities from the Horn of Africa. Preventive health programmes with Horn of Africa refugees need to acknowledge the effect of acculturation on diet and physical activity levels and a socio-cultural framework needs to be developed with respect to the importance and influence of the family environment.

Evidence supports the use of pricing interventions in achieving healthier behaviour at population level. The public acceptability of this strategy continues to be debated throughout Europe, Australasia and USA. We examined public attitudes towards, and beliefs about the acceptability of pricing policies to change health-related behaviours in the UK. The study explores what underlies ideas of acceptability, and in particular those values and beliefs that potentially compete with the evidence presented by policy-makers. Twelve focus group discussions were held in the London area using a common protocol with visual and textual stimuli. Over 300,000 words of verbatim transcript were inductively coded and analyzed, and themes extracted using a constant comparative method. Attitudes towards pricing policies to change three behaviours (smoking, and excessive consumption of alcohol and food) to improve health outcomes, were unfavourable and acceptability was low. Three sets of beliefs appeared to underpin these attitudes: (i) pricing makes no difference to behaviour; (ii) government raises prices to generate income, not to achieve healthier behaviour and (iii) government is not trustworthy. These beliefs were evident in discussions of all types of health-related behaviour. The low acceptability of pricing interventions to achieve healthier behaviours in populations was linked among these responders to a set of beliefs indicating low trust in government. Acceptability might be increased if evidence regarding effectiveness came from trusted sources seen as independent of government and was supported by public involvement and hypothecated taxation. © The Author 2015.

Objectives: To investigate the concept of clinical governance being advocated by primary care groups/trusts (PCG/Ts), approaches being used to implement clinical governance, and potential barriers to its successful implementation in primary care. Design: Qualitative case studies using semi-structured interviews and documentation review. Setting: Twelve purposively sampled PCG/Ts in England. Participants: Fifty senior staff including chief executives, clinical governance leads, mental health leads, and lay board members. Main outcome measures: Participants' perceptions of the role of clinical governance in PCG/Ts. Results: PCG/Ts recognise that the successful implementation of clinical governance in general practice will require cultural as well as organisational changes, and the support of practices. They are focusing their energies on supporting practices and getting them involved in quality improvement activities. These activities include, but move beyond, conventional approaches to quality assessment (audit, incentives) to incorporate approaches which emphasise corporate and shared learning. PCG/Ts are also engaged in setting up systems for monitoring quality and for dealing with poor performance. Barriers include structural barriers (weak contractual levers to influence general practices), resource barriers (perceived lack of staff or money), and cultural barriers (suspicion by practice staff or problems overcoming the perceived blame culture associated with quality assessment). Conclusion: PCG/Ts are focusing on setting up systems for implementing clinical governance which seek to emphasise developmental and supportive approaches which will engage health professionals. Progress is intentionally incremental but formidable challenges lie ahead, not least reconciling the dual role of supporting practices while monitoring (and dealing with poor) performance.

Aims To investigate young people’s attitudes to, and understanding of, physical activity on glycaemic control in Type 1 Diabetes Mellitus. Methods Four focus groups with 11–14 and 15–16 year olds were conducted with twelve young people with Type 1 Diabetes, from within a larger study investigating physical activity and fitness. Qualitative analysis of the focus group data was performed using Interpretative Phenomenological Analysis. Results Four superordinate themes were identified: Benefits of Exercise, Knowledge and Understanding, Information and Training and “You can do anything”. Young people felt that exercising helped them to manage their diabetes and had a beneficial psychological and physical impact on their bodies. They reported a lack of knowledge and understanding about diabetes among school staff and other young people. The overwhelming sense from young people was that although diabetes impacts upon their lives, with preparation, physical activity can take place as normal. Conclusions Whilst young people had an awareness of the physical and psychological benefits of exercise in managing their diabetes, they experienced difficulties at school. Professional support and discussions with young people, giving tailored strategies for managing Type 1 Diabetes during exercise are needed. Healthcare teams should ensure that the support and educational needs of school staff are met. Providing more opportunities to empower young people to take on the responsibility for their Type 1 Diabetes care is merited. Young people felt diabetes did not stop them from participating in activities; it is simply a part of them that needs managing throughout life. PMID:26465770

Low patient adherence to treatment is associated with poorer health outcomes in bronchiectasis. We sought to use the Theoretical Domains Framework (TDF) (a framework derived from 33 psychological theories) and behavioural change techniques (BCTs) to define the content of an intervention to change patients' adherence in bronchiectasis (Stage 1 and 2) and stakeholder expert panels to define its delivery (Stage 3). We conducted semi-structured interviews with patients with bronchiectasis about barriers and motivators to adherence to treatment and focus groups or interviews with bronchiectasis healthcare professionals (HCPs) about their ability to change patients' adherence to treatment. We coded these data to the 12 domain TDF to identify relevant domains for patients and HCPs (Stage 1). Three researchers independently mapped relevant domains for patients and HCPs to a list of 35 BCTs to identify two lists (patient and HCP) of potential BCTs for inclusion (Stage 2). We presented these lists to three expert panels (two with patients and one with HCPs/academics from across the UK). We asked panels who the intervention should target, who should deliver it, at what intensity, in what format and setting, and using which outcome measures (Stage 3). Eight TDF domains were perceived to influence patients' and HCPs' behaviours: Knowledge, Skills, Beliefs about capability, Beliefs about consequences, Motivation, Social influences, Behavioural regulation and Nature of behaviours (Stage 1). Twelve BCTs common to patients and HCPs were included in the intervention: Monitoring, Self-monitoring, Feedback, Action planning, Problem solving, Persuasive communication, Goal/target specified:behaviour/outcome, Information regarding behaviour/outcome, Role play, Social support and Cognitive restructuring (Stage 2). Participants thought that an individualised combination of these BCTs should be delivered to all patients, by a member of staff, over several one-to-one and/or group visits in secondary care. Efficacy should be measured using pulmonary exacerbations, hospital admissions and quality of life (Stage 3). Twelve BCTs form the intervention content. An individualised selection from these 12 BCTs will be delivered to all patients over several face-to-face visits in secondary care. Future research should focus on developing physical materials to aid delivery of the intervention prior to feasibility and pilot testing. If effective, this intervention may improve adherence and health outcomes for those with bronchiectasis in the future.

To investigate whether Erigeron Breviscapus (Vant.) Hand-Mazz (EBHM) can improve the optic nerve axoplasmic transport in rats with experimentally elevated intraocular pressure (IOP). Thirty healthy SD rats were used for the study, acute elevated IOP model in the right eye was built, then they were divided into three groups randomly: Group A (0 day group) included six rats for retinal ganglion cell (RGC) counting via left superior colliculus retrograde horse radish perokidase labeling; Group B, twelve rats divided into EBHM treatment group and control group (6 rats in each subgroup) for RGC counting via left superior colliculus retrograde labeling after twenty days, and Group C included twelve rats submitted the same treatment and procedure as group B after 40 days. After 0 day of acute elevated IOP, no labeled RGCs were observed. After twenty days of acute elevated IOP, in the control and EBHM subgroups the density of labeled RGCs were (423 +/- 220)/mm(2) and (749 +/- 294)/mm(2) respectively, the difference between two subgroups showed statistical significance (P < 0.01). After 40 days of acute elevated IOP, the density of RGCs in the control and EBHM subgroups in group C were (610 +/- 315)/mm(2) and (1,048 +/- 393)/mm(2) respectively, the difference between the two subgroups being statistically significant (P < 0.01). After 20 days and 40 days of acute elevation of IOP, the density of RGCs is obviously higher in EBHM group than that in the control group. It is revealed that EBHM can improve the optic nerve axoplasmic transportation blocked by acute elevation of IOP in rats.

Medical students have limited confidence in performing procedural skills. A pilot study was conducted to evaluate the effect of a multifaceted Procedural Skills Lab (PSL) on the confidence of medical students to perform procedural skills. Twelve 2nd year medical students were randomly selected to participate in a pilot PSL. The PSL students met with an instructor for 2 h once a week for 4 weeks. Students participated in a flipped classroom and spaced education program before laboratory sessions that included a cadaver laboratory. Procedural skills included a focused assessment with sonography in trauma (FAST) scan, cardiac echocardiogram, lumbar puncture, arthrocentesis, and insertion of intraosseous and intravenous catheters. Students in the PSL were asked to rank their confidence in performing procedural skills before and after completion of the laboratory sessions (Wilcoxon ranked-sum test). A web-based questionnaire was also emailed to all 2nd year medical students to establish a baseline frequency for observing, performing, and confidence performing procedural skills (Mann-Whitney U-test). Fifty-nine percent (n = 106) of 180 2nd year medical students (n = 12 PSL students [treatment group], n = 94 [control group]) completed the survey. Frequency of observation, performance, and confidence in performing procedural skills was similar between the control and treatment groups at baseline. There was an increased confidence level (p < 0.001) for performing all procedural skills for the treatment group after completion of the PSL. An innovative PSL may increase students' confidence to perform procedural skills. Future studies will examine competency after a PSL.

In this study we assessed the behavioral presentation of social anxiety in Cornelia de Lange syndrome (CdLS) using a contrast group of Cri du Chat syndrome (CdCS). Behaviors indicative of social anxiety were recorded in twelve children with CdLS (mean age = 11.00; SD = 5.15) and twelve children with CdCS (8.20; SD = 2.86) during social interaction. Lag sequential analysis revealed that participants with CdLS were significantly more likely to evidence behavior indicative of anxiety in close temporal proximity to the point at which they maintained eye contact or spoke. Individuals with CdLS demonstrate a heightened probability of anxiety related behavior during social interaction but only at the point at which social demand is high.

This study was designed to explore the relationship in between the daily consumption of fish oil (360mg DHA+540mg EPA), and reduction of symptoms and violent behavior among patients with schizophrenia. Fifty inpatients meeting ICD-10 criteria for schizophrenia and scoring more than four of Modified Overt Aggression Scale (MOAS) with antipsychotics treatment were randomly assigned to receive either fish oil (N=28) or a placebo (N=22) in a twelve week, double-blind supplementation trial. Assessments were performed at baseline and at weeks 4, 8 and 12. The PANSS and CGI scores decreased at the week of 4, 8 and 12, but no differences were found between the two groups. MOAS scores declined significantly at weeks 4, 8 and 12. At week 12, MOAS scores of the fish oil group declined significantly than the placebo group (t=-2.40, P<0.05). violent schizophrenia patients treated with fish oil (360mg DHA+540mg EPA) demonstrated a decrease in violence, but improvement in positive and negative symptoms was no greater than patients treated with the placebo after twelve weeks.

Alkaptonuria (AKU) is an autosomal recessive disorder caused by mutations in homogentisate-1,2-dioxygenase (HGD) gene leading to the deficiency of HGD enzyme activity. The DevelopAKUre project is underway to test nitisinone as a specific treatment to counteract this derangement of the phenylalanine-tyrosine catabolic pathway. We analysed DNA of 40 AKU patients enrolled for SONIA1, the first study in DevelopAKUre, and of 59 other AKU patients sent to our laboratory for molecular diagnostics. We identified 12 novel DNA variants: one was identified in patients from Brazil (c.557T>A), Slovakia (c.500C>T) and France (c.440T>C), three in patients from India (c.469+6T>C, c.650-85A>G, c.158G>A), and six in patients from Italy (c.742A>G, c.614G>A, c.1057A>C, c.752G>A, c.119A>C, c.926G>T). Thus, the total number of potential AKU-causing variants found in 380 patients reported in the HGD mutation database is now 129. Using mCSM and DUET, computational approaches based on the protein 3D structure, the novel missense variants are predicted to affect the activity of the enzyme by three mechanisms: decrease of stability of individual protomers, disruption of protomer-protomer interactions or modification of residues in the region of the active site. We also present an overview of AKU in Italy, where so far about 60 AKU cases are known and DNA analysis has been reported for 34 of them. In this rather small group, 26 different HGD variants affecting function were described, indicating rather high heterogeneity. Twelve of these variants seem to be specific for Italy.

A phenomenological analysis of the essence of the science education experience as perceived by female high school physics and advanced chemistry students

NASA Astrophysics Data System (ADS)

Papadimitriou, Michael

The purpose of this phenomenological study was to describe the essential elements of the current science education experience as constructed by twelve female high school physics and advanced chemistry students. The expressed desired outcome was a description of the phenomenon from a participant point of view. Student recollections and interpretations of experiences were assessed for a twelve-week period. Data sources were student journals, autobiographies, interviews, focus group interviews and researcher observations. In addition, each participant completed the Test of Science Related Attitudes (Fraser, 1981) in order to create attitude profiles for triangulation with other data. While a wide range of aspects of the science education experience emerged, results showed that female students describe and interpret their science education experiences on the basis of actual interest in science, early science experiences, perception of ability, self-confidence, teacher attributes, parental and peer interaction, societal expectations, the nature of science, and gender. Of these factors, specifically, interest and curiosity, societal influence, the nature of science, lack of in-school experiences, the desire to help others, and general parent support were most impacting upon experience and the desire to continue science study. Moreover, the interaction of these factors is relevant. Very simply, early experiences are crucial to interest development. In general, parents can enhance this interest by providing science-related experiences. In the absence of early in-school experiences (i.e., which the participants reported), these out-of-school experiences become crucial. More importantly, quality instruction and parent and peer support are needed to foster science interest and to overcome the powerfully negative influence of society, the discriminatory nature of science, and the lack of experiences.

Hyperactivation of working memory related brain circuits in newly-diagnosed middle-aged type 2 diabetics

Type 2 diabetes mellitus (T2DM) is well known for its adverse impacts on brain and cognition, which lead to multidimensional cognitive deficits and wildly-spread cerebral structure abnormalities. However, existing literatures are mainly focused on patients with advanced age or extended T2DM duration. Therefore, it remains unclear whether and how brain function would be affected at the initial onset stage of T2DM in relatively younger population. In current study, twelve newly-diagnosed middle-aged T2DM patients with no previous diabetic treatment history and twelve matched controls were recruited. Brain activations during a working memory task, the digit n-back paradigm (0-, 1- and 2-back), were obtained with functional magnetic resonance imaging (fMRI) and tested by repeated measures ANOVA. Whereas patients performed the n-back task comparably well as controls, significant load-by-group interactions of brain activation were found in the right dorsolateral prefrontal cortex (DLPFC), left middle/inferior frontal gyrus, and left parietal cortex, where patients exhibited hyperactivation in the 2-back but not the 0-back or 1-back condition compared to controls. Furthermore, the severity of chronic hyperglycemia, estimated by glycosylated hemoglobin (HbA1c) level, was entered into partial correlational analyses with task-related brain activations, while controlling for the real-time influence of glucose, estimated by instant plasma glucose level measured before scanning. Significant positive correlations were found between HbA1c and brain activations in the anterior cingulate cortex and bilateral DLPFC only in patients. Taken together, these findings suggest there might be a compensatory mechanism due to brain inefficiency related to chronic hyperglycemia at the initial onset stage of T2DM. PMID:24993663

Ankaferd Blood Stopper (ABS) is a new promising local hemostatic agent, and its mechanism on hemostasis has been shown by many studies. However, the effects of ABS on skin superoxide dismutase (SOD) and catalase (CAT) activities have not been investigated before. The aim of this study was to evaluate the effects of this new generation local hemostatic agent on warfarin-treated rats focusing on its the antioxidant potential in short-term soft tissue healing. Twelve systemically warfarin treated (warfarin group) and 12 none treated Wistar Albino rats (control group) were selected for the trial. Rats in the warfarin group were treated intraperitonally with 0.1 mg/kg warfarin, and rats in the control group were given 1 mL/kg saline 3 days earlier to surgical procedure and continued until killing. All rats had incisions on dorsal dermal tissue, which was applied ABS or no hemostatic agent before suturing. Six of each group were killed on day 4, and the other 6 were killed on day 8. Blood and skin samples were taken. Prothrombin time (PT) in blood samples, CAT, and SOD activities in skin samples were determined. Warfarin treatment dose was found to be convenient and warfarin treatment increased the PT levels as expected. Warfarin treatment decreased CAT activity significantly compared to the control group. The ABS treatment significantly increased SOD activities in the warfarin group at the end of the eighth day. Ankaferd Blood Stopper acted positively in short-term tissue healing by increasing SOD activity in warfarin-treated rats. Therefore, ABS may be suggeted as a promoting factor in tissue healing.

Evidence concerning predictability of narrow-diameter implants (NDIs) (<3.3 mm) to restore partially edentulous posterior maxillary and mandibular areas is limited. The aim of this study is to compare the 5-year outcomes of NDIs (3.0 mm) and standard-diameter implants (SDIs) (4.0 to 4.5 mm) supporting fixed partial dentures (FPDs) in posterior mandibular and maxillary jaws. All patients treated with at least two adjacent NDIs or SDIs according to available bone thickness and with a minimum follow-up of 5 years after placement were invited to undergo a clinical and radiologic examination. Outcome measures were implant and FPD failures, biologic and prosthetic complications, and marginal bone loss. A total of 107 out of 127 patients attended the examination: 49 (113 implants) of the NDI group, and 58 (126 implants) of the SDI group. Two NDIs failed in one patient versus four SDIs in four patients (P = 0.37). One FPD failed in the NDI group versus two FPDs in the SDI group (P >0.99). Nine biologic complications occurred in the NDI group and twelve in the SDI group (P = 0.81). Twelve prosthetic complications occurred in the NDI group and only two in the SDI group (P = 0.001). Peri-implant marginal bone loss at 5 years was 0.95 ± 0.84 mm for the NDI group and 1.2 ± 0.86 mm for the SDI group (P = 0.06). Five-year data indicate that FPD treatment in posterior mandibular and maxillary jaws with NDIs was as reliable as with SDIs, although NDIs showed a higher risk of prosthetic complications.

Many patients with anxiety or depressive disorders achieve no remission of their symptoms after evidence-based treatment algorithms. They develop a chronic course of the disorder. Current care for these patients usually consists of long-term supportive contacts with a community psychiatric nurse and pharmacological management by a psychiatrist. Data on the effectiveness of these treatments is lacking. A psychosocial rehabilitation approach, where self-management is an increasingly important part, could be more suitable. It focuses on the restoration of functioning and enhancement of patients' autonomy and responsibility. Treatment with this focus, followed by referral to primary care, may be more (cost-)effective. A multicenter randomized controlled trial is designed for twelve participating specialized outpatient mental health services in the Netherlands. Patients with chronic and treatment resistant anxiety or depressive disorders, currently receiving supportive care in specialized outpatient mental health care, are asked to participate. After inclusion, patients receive the baseline questionnaire and are randomized to the intervention group or the usual care control group. The intervention focuses on rehabilitation and self-management and is provided by a trained community psychiatric nurse, followed by referral to primary care. Measurements take place at 6, 12, and 18 months after baseline. This study evaluates both the effectiveness (on quality of life, symptom severity, and empowerment), and cost-effectiveness of the intervention compared to usual care. In addition, a questionnaire is designed to get insight in which self-management strategies patients use to manage their disorder, and in the experiences of patients with the change of care setting. In this study we evaluate the effectiveness and cost-effectiveness of a self-management intervention for patients with chronic and treatment resistant anxiety or depressive disorders in specialized outpatient mental health care. The results of this study may provide a first 'proof-of-concept' in this under-researched but important field, and might be relevant for a large group of patients in the context of a transition of the Dutch health care system.

Objective: to identify the best low intensity laser photobiomodulation application site to increase the viability of the cutaneous flap in rats. Methods: 18 male rats (Rattus norvegicus: var. Albinus, Rodentia Mammalia) were randomly distributed into 3 groups (n = 6). Group I (GI) was submitted to simulated laser photobiomodulation, group II (GII) was submitted to the laser photobiomodulation at three points in the flap cranial base, and group III (GIII) was submitted to laser photobiomodulation at twelve points distributed along the flap. All groups were irradiated with an Indium, Galium, Aluminum and Phosphorus diode laser (InGaAlP), 660 nm, with power of 50 mW, total energy of 12 J in continuous emission mode. The treatment started immediately after performing the cranial base random skin flap (dimension of 10X4 cm2 ) and reapplied every 24 hours, with a total of 5 applications. The animals were euthanized after the evaluation of the percentage of necrosis area and the material was collected for histological analysis on the 7th postoperative day. Results: GII animals presented a statistically significant decrease for the necrosis area when compared to the other groups, and a statistically significant increase in the quantification of collagen when compared to the control. We did not observe a statistical difference between the TGFβ and FGF expression in the different groups evaluated. Conclusion: the application of laser photobiomodulation at three points of the flap cranial base was more effective than at twelve points regarding the reduction of necrosis area.

To investigate the mechanism of the action of glucocorticoid induced leucine zipper (GILZ) in inflammatory reaction. Human monocyte cell line THP-1 cells were divided into two groups and cultured in non-serum RPMI1640 medium.In one group the cells were treated with dexamethasone (DEX). Twelve hours later total RNA and total protein were abstracted in both two groups. The mRNA encoding for expression of GILZ was semiquantitatively detected by reserve transcriptase-polymerase chain reaction (RT-PCR). Protein expression of nuclear factor-KappaB (NF-KappaB) p65 and activator protein-1 (AP-1) were assessed by Western blotting. Peripheral blood of 10 trauma patients [injury severity score (ISS) >or=16 scores] were collected and the leukocytes were isolated within 24 hours after trauma. The leukocytes were divided into two groups and cultured in non-serum medium. In one group the cells were treated with DEX. Twelve hours later total RNA and total protein were abstracted in both two groups. The mRNA encoding for expression of GILZ was semiquantitatively detected by RT-PCR. Protein expression of NF-KappaB p65 and AP-1 were assessed by Western blotting. Stimulated by DEX, the expression of GILZ mRNA was increased both in THP-1 cells and the leukocytes of trauma patients compared with those of control groups (both P<0.01). Whereas, protein expressions of NF-KappaB p65 and AP-1 of THP-1 cells and leukocytes in peripheral blood of trauma patients were decreased in the stimulation groups compared with those of control groups (all P<0.01). The expression of GILZ gene is up-regulated by glucocorticoid. Overexpression of GILZ inhibits NF-KappaB and AP-1 activities, suggesting that GILZ possesses anti-inflammatory function.

Low back pain is a common health problem in human being and about 5 to 15% will develop chronic low back pain (CLBP). The clinical findings of CLBP suggest that lumbar mobility is decreased and recruitment order of core muscles is altered. In literature, there is no data about the effect of core muscles strengthening in the chronicity (short duration, long duration) of CLBP. This study evaluated the effect of core muscle strengthening intervention on chronicity of chronic low back pain. Thirty patients were recruited from the outpatient department of the National Institute for the Orthopaedically Handicapped. These 30 patients divided into two groups: A and B on the basis of duration of low back pain. Group-A patients complain about pain duration for more than twelve months and Group B complains about pain duration from three to twelve months. Both the groups were received same intervention for six weeks. Assessment was done pre intervention and post intervention after six weeks for both the groups. %For both the groups the assessment was done after six weeks for pre and post intervention. The result described both the groups showed improvement in all the outcome measures including pain as well as in function using Numerical pain rating scale, Oswestry Disability Index, Sorensen test, Gluteus Maximus Strength, Activation of transversus abdominis and Modified-Modified Schober's Test. The improvement was statistically non-significant with inter groups and significant within group. This study concludes that core muscle strengthening exercise along with lumbar flexibility and gluteus maximus strengthening is an effective rehabilitation technique for all chronic low back pain patients irrespective of duration (less than one year and more than one year) of their pain.

Ten endogamous population groups of West Bengal (India)--Rabhas, Garos, Mechs, Rajbanshis, Jalia Kaibartas, Bagdis, Lodhas, Mundas, Brahmins, Vaidyas--have been typed for twelve polymorphic systems: ABO, Gm, Km, Hp, Cp, Tf, Alb, Hb, aP, EsD, AK and PGM1. The results are compared with those obtained on other Indian populations. Serological and anthropometric data, which have been included into population comparisons, reveal a considerable genetic variability of the groups under study. This variability is obviously connected with the population history of West Bengal.

Radial resolution enhancement of the NSTX Thomson scattering diagnostic.

LeBlanc, B P; Diallo, A; Labik, G; Stevens, D R

2012-10-01

Current magnetic confinement plasma physics research has increased the demand for radial resolution in profile diagnostics, in particular in the edge and pedestal regions. On NSTX, an upgrade of the existing multi-point Thomson scattering diagnostic has been implemented in order to respond to the research program needs. Twelve new radial channels have been added bringing the total number of positions to 42. Four previously un-instrumented fiber bundles were put in service. Eight existing "active" fiber bundles were divided in two sub-bundles each in order to increase spatial resolution. Twelve radial channels now cover the pedestal region with a resolution near one centimeter. Fifteen radial channels cover the core and internal transport barrier regions. Two additional channels were added, one near the inner edge and one in the outer scrape-off layer. The intersection of the focused viewing optics field of view with a finite-width laser beam results in major-radius cross talk between adjacent fiber sub-bundles. A discussion and calculation of the cross talk will be presented.

Imitation is a complex process that includes higher-order cognitive and motor function. This process requires an observation-execution matching system that transforms an observed action into an identical movement. Although the low-gamma band is thought to reflect higher cognitive processes, no studies have focused on it. Here, we used magnetoencephalography (MEG) to examine the neural oscillatory changes including the low-gamma band during imitation. Twelve healthy, right-handed participants performed a finger task consisting of four conditions (imitation, execution, observation, and rest). During the imitation and execution conditions, significant event-related desynchronizations (ERDs) were observed at the left frontal, central, and parietal MEG sensors in the alpha, beta, and low-gamma bands. Functional connectivity analysis at the sensor level revealed an imitation-related connectivity between a group of frontal sensors and a group of parietal sensors in the low-gamma band. Furthermore, source reconstruction with synthetic aperture magnetometry showed significant ERDs in the low-gamma band in the left sensorimotor area and the middle frontal gyrus (MFG) during the imitation condition when compared with the other three conditions. Our results suggest that the oscillatory neural activities of the low-gamma band at the sensorimotor area and MFG play an important role in the observation-execution matching system related to imitation.

Social Café Meals Programs aim to reduce food insecurity and social exclusion by providing participants access to subsidised meals in mainstream local cafés. This study aimed to explore the program's ability to address social exclusion and food insecurity and the impact of the program on the community. A qualitative evaluation approach was utilised whereby in-depth interviews were conducted with café owners, café staff and current program members of two Social Café Meals Programs operating in the south-eastern suburbs of Melbourne. Twelve program members and six café staff completed an in-depth interview at the local cafés. Data were analysed using a thematic analysis approach focusing on the lived experience of the café owners, staff and program members. Four key themes were identified. The program (i) improved food access for vulnerable groups and (ii) created community cohesiveness. (iii) The café environment was important in facilitating program use by community members. (iv) Café owners felt rewarded for their community contribution via the program. Social Café Meals Programs may provide a solution to improving food security and reducing social exclusion and may be considered as a strategy for improving nutrition and social health for at-risk and vulnerable groups.

The aim of this study was to analyze the significance of an increase in total prostate-specific antigen (PSA) serum levels despite dutasteride treatment as a predictor of prostate cancer (PC) at biopsy. We focused our attention on the rate of the first PSA increase and on the influence of prostatic inflammation. From 2011 to 2016, 365 men with a previous negative prostate biopsy and persistent elevated PSA levels received dutasteride treatment. The population was followed for a range of 12-48 months. One hundred twelve cases with a confirmed PSA increase >0.5 ng/ml over the nadir value during the follow-up were included in Group A and underwent a new prostate biopsy. In Group A, the PSA increase was associated with PC at the re-biopsy in 66% of cases. The percentage of PSA reduction after 6 months of treatment was not a significant indicator of the risk for PC. The distribution of inflammatory infiltrates significantly (p<00.01) varied from positive to negative prostate biopsies. The relative risk for PC at biopsy significantly increased according to PSA level during dutasteride. Treatment with dutasteride can help to analyze PSA kinetic. A persistent prostatic inflammation is a factor able to reduce the performance of PSA kinetic during dutasteride treatment.

The current study focused on validating a protocol for training and auditing the resident's practice-based learning and improvement (PBLI) and quality improvement (QI) competencies for primary care. Twelve second-year (R2), 12 first-year (R1) and 12 postgraduate year-1 residents were enrolled into group A, B and C, respectively, as trainees. After three training protocols had been completed, a writing test, self-assessed questionnaire and mini-OSTE and end-of-rotation assessment were used in auditing the PBLI competency, performance and teaching ability of trainees. Baseline expert-assessed PBLI and QI knowledge application tool writing scores were low for the R1 and R2 residents. After three training protocols, PBLI and QI proficiencies, performance and teaching abilities were improved to similar levels cross the three training levels of residents based on the expert-assessed writing test-audited assessments and on the faculty and standardized clerk-assessed end-of-rotation-/mini-OSTE-audited assessments. The different four-level hierarchical protocols used to teach group A, B and C were equally beneficial and fitted their needs; namely the different levels of the trainees. Specifically, each level was able to augment their PBLI and QI proficiency. This educational intervention helps medical institutions to train residents as PBLI instructors.

What do parents think about parental participation in school-based interventions on energy balance-related behaviours? a qualitative study in 4 countries

PubMed Central

2011-01-01

Background Overweight and obesity in youth has increased dramatically. Therefore, overweight prevention initiatives should start early in life and target modifiable energy balance-related behaviours. Parental participation is often advocated as important for school-based interventions, however, getting parents involved in school-based interventions appears to be challenging based on earlier intervention experiences. The purpose of this study was to get insight into the determinants of and perspectives on parental participation in school-interventions on energy balance-related behaviours (physical activity, healthy eating, sedentary behaviours) in parents of ten- to twelve-year olds in order to develop an effective parental module for school-based interventions concerning energy balance-related behaviours. Methods Four countries (Belgium, Hungary, Norway and Spain) conducted the focus group research based on a standardised protocol and a semi-structured questioning route. A variation in parental socio-economic status (SES) and parental school involvement was taken into account when recruiting the parents. The audio taped interviews were transcribed, and a qualitative content analysis of the transcripts was conducted in each country. Results Seventeen focus group interviews were conducted with a total of 92 parents (12 men, 80 women). Physical activity was considered to be a joint responsibility of school and parents, nutrition as parent's responsibility but supported by the school, and prevention of sedentary behaviours as parent's sole responsibility. Parents proposed interactive and practical activities together with their child as the best way to involve them such as cooking, food tasting, nutrition workshops, walking or cycling tours, sport initiations together with their child. Activities should be cheap, on a convenient moment, focused on their children and not on themselves, not tutoring, not theoretical, and school-or home-based. Conclusions Parents want to be involved in activities related to energy balance-related behaviours if this implies 'doing things together' with their child at school or at home. PMID:22112159

This paper provides a comprehensive review of the recent literature on Native Hawaiian youth and substance use. Eight-hundred and twelve potential articles pertaining to Native Hawaiian youth and substance use published between 1995 to May 2009 were identified through an exhaustive literature search. The total number of articles was reduced to 32 articles, which were systematically coded and content analyzed. The findings indicated that the majority of studies focused on epidemiology, with relatively few of them focused on causal factors/etiology and systematic program development or evaluation. Gender differences in drug use were highlighted in several studies. Implications for culturally-tailored interventions and future research are discussed. PMID:20737343

2017-04-01

This review examines the efficacy and safety of repetitive transcranial magnetic stimulation (rTMS) as a treatment for treatment-resistant depression in adolescents. A systematic review of six databases was conducted. Ten multi-subject trials, all uncontrolled, and five case reports met inclusion criteria. Twelve studies focused on treatment efficacy, whereas three studies focused exclusively on adverse events. All efficacy studies focused on adolescents only; 10 of these studies indicated that rTMS may demonstrate some benefit. Improvement within 2-8 weeks was reported in most studies, with a few studies indicating potential long-term benefits. A variety of adverse events occurred including scalp pain, which was the most common, as well as seizures. Controlled studies of rTMS are warranted to further examine whether this treatment is a potential option for adolescents with treatment-resistant depression.

The Cerebral Palsy Computerized Adaptive Test (CP-CAT) is a parent-reported outcomes instrument for measuring lower and upper-extremity function, activity, and global health across impairment levels and a broad age range of children with cerebral palsy (CP). This study was performed to examine whether the Lower Extremity/Mobility (LE) CP-CAT detects change in mobility following orthopaedic surgery in children with CP. This multicenter, longitudinal study involved administration of the LE CP-CAT, the Pediatric Outcomes Data Collection Instrument (PODCI) Transfer/Mobility and Sports/Physical Functioning domains, and the Timed "Up & Go" test (TUG) before and after elective orthopaedic surgery in a convenience sample of 255 children, four to twenty years of age, who had CP and a Gross Motor Function Classification System (GMFCS) level of I, II, or III. Standardized response means (SRMs) and 95% confidence intervals (CIs) were calculated for all measures at six, twelve, and twenty-four months following surgery. SRM estimates for the LE CP-CAT were significantly greater than the SRM estimates for the PODCI Transfer/Mobility domain at twelve months, the PODCI Sports/Physical Functioning domain at twelve months, and the TUG at twelve and twenty-four months. When the results for the children at GMFCS levels I, II, and III were grouped together, the improvements in function detected by the LE CP-CAT at twelve and twenty-four months were found to be greater than the changes detected by the PODCI Transfer/Mobility and Sports/Physical Functioning scales. The LE CP-CAT outperformed the PODCI scales for GMFCS levels I and III at both of these follow-up intervals; none of the scales performed well for patients with GMFCS level II. The results of this study showed that the LE CP-CAT displayed superior sensitivity to change than the PODCI and TUG scales after musculoskeletal surgery in children with CP.

2012-10-01

The objective of this study was to assess the effect of physician practicing preferences (PPP) in primary care for homeopathy (Ho), CAM (Complementary and alternative medicines) with conventional medicine (Mx) or exclusively conventional medicine (CM) on patients with musculoskeletal disorders (MSDs), with reference to clinical progression, drug consumption, side effects and loss of therapeutic opportunity. The EPI3-MSD study was a nationwide observational cohort of a representative sample of general practitioners (GP) and their patients in France. Recruitment of GP was stratified by PPP, which was self-declared. Diagnoses and comorbidities were recorded by GP at inclusion. Patients completed a standardized telephone interview at inclusion, one, three and twelve months, including MSD-functional scales and medication consumption. 1153 MSD patients were included in the three PPP groups. Patients did not differ between groups except for chronicity of MSDs (>12 weeks), which was higher in the Ho group (62.1%) than in the CM (48.6%) and Mx groups (50.3%). The twelve-month development of specific functional scores was identical across the three groups after controlling for baseline score (p > 0.05). After adjusting for propensity scores, NSAID use over 12 months was almost half in the Ho group (OR, 0.54; 95%CI, 0.38-0.78) as compared to the CM group; no difference was found in the Mx group (OR, 0.81; 95% CI: 0.59-1.15). MSD patients seen by homeopathic physicians showed a similar clinical progression when less exposed to NSAID in comparison to patients seen in CM practice, with fewer NSAID-related adverse events and no loss of therapeutic opportunity.

2018-05-01

Navigated computer-assisted total knee arthroplasty (TKA) was introduced to expedite long-term survival based on improved postoperative implantation accuracy. However, long-term outcome data after 10 years or more are rare, even available meta-analyses show controversial study results. In a prospective randomized trial, 100 conventional TKAs (group CONV) were compared with 100 computer-assisted TKAs (group NAV) after a mean follow-up of 12 years postoperatively. A long-leg weight-bearing X-ray was performed for measuring mechanical axis of the limb, lateral distal femoral angle, and medial proximal tibial angle. Tibial slope, patella alpha angle, and radiolucent lines were also observed. Clinical investigation included evaluation of 4 different scores: Insall Knee Score, Western Ontario and MacMaster University Index score, Hospital for Special Surgery Knee Score, and visual analog scale. Based on a follow-up rate of at least 75%, no difference in TKA survival was found 12 years postoperatively: 91.5% in group CONV vs 98.2% in group NAV (P = .181). Since 5-year follow-up, no additional TKA revision had been performed in both groups. Group CONV showed a nonsignificant higher inaccuracy of neutral lower limb axis (1.8° ± 1.4°) compared to group NAV (1.6° ± 1.7°, P = .700). All X-ray assessments were not significant different within both study groups (P ≥ .068). Clinical examination showed no differences in evaluations (P ≥ .204). All collected outcome score results were similar (P ≥ .222). Twelve years postoperatively, no differences were found in terms of long-term survival, implantation accuracy, clinical outcome or score results. Copyright © 2017 Elsevier Inc. All rights reserved.

Some patients with refractory peritoneal dialysis-related peritonitis continue to develop intra-abdominal complications despite removal of the peritoneal catheter. Repeated percutaneous drainage or open laparotomy is often required, and mortality is not uncommon. The benefits of pelvic drainage placement during catheter removal in decreasing these complications and interventions remain unproven. Forty-six patients with refractory peritonitis who underwent removal of a Tenckhoff catheter between 1991 and 2013 were reviewed retrospectively. Twelve patients had pelvic drainage using closed active suction devices during catheter removal (drainage group). The remaining 34 patients underwent catheter removal without drainage (non-drainage group). The outcomes measured were the development of intra-abdominal complications and the requirement for repeated percutaneous drainage or open laparotomy within 90 days after the catheter removal. Baseline characteristics were similar with the exception of a higher median number of previous peritonitis episodes in the drainage group compared with the non-drainage group (2 vs 0, P = 0.02). During the follow-up period, intra-abdominal complications occurred in 15 (44%) of 34 patients in the non-drainage group, compared with one (8%) of 12 patients in the drainage group (P = 0.03). Twelve (35%) patients in the non-drainage group required repeated percutaneous drainage or open laparotomy for management, compared with zero (0%) patients in the drainage group (P = 0.02). Drain tubes were removed at a median of 6 days (inter-quartile range: 5-10) without complications. In the management of refractory peritonitis, pelvic drainage during removal of dialysis catheter decreases the risk of subsequent intra-abdominal complications and invasive interventions. © 2015 Asian Pacific Society of Nephrology.

Background Patient preference may influence intervention effects, but has not been extensively studied. Randomized controlled design (N=1075) assessed outcomes when women (60 years +) were given a choice of two formats of a program to enhance heart disease management. Methods Randomization to "no choice" or "choice" study arms. Further randomization of "no choice” to: 1) Group intervention program format, 2) Self-Directed program format, 3) Control Group. "Choice" arm selected their preferred program format. Baseline, four, twelve, and eighteen month follow-up data collected. Two analyses: health outcomes for choice compared to being randomized; and preference effect on treatment efficacy. Results Women who chose a format compared to being assigned a format had better psychosocial functioning at four months (p=0.02) and tended toward better physical functioning at twelve months (p=0.07). At eighteen months women who chose versus being assigned a format had more symptoms measured as: number (p=0.004), frequency (p=0.006) and bother (p=0.004). At four months women who preferred the Group format had better psychosocial functioning when assigned the Group format than when they were assigned the Self Directed format (p=0.03). At eighteen months women preferring a Group format had more symptoms: number (p=0.001), frequency (p=0.001), bother (p=0.001) when assigned the Group format than when assigned the Self Directed format. Conclusions Choice and preference for the Group format each enhanced psychosocial and physical functioning up to one year. Despite the preference for Group format, over the longer term (eighteen months) cardiac symptoms were fewer when assigned the Self-Directed format. PMID:18515187

Is pregnancy over 45 with very high parity related with adverse maternal and fetal outcomes?

To examine whether very high parity and age over 45 years are related with adverse maternal and fetal outcomes. This study was carried out at the Department of Obstetrics and Gynecology from January 1, 2007 to December 31, 2007. Sixty-one pregnant women were enrolled in this prospective study. Mothers were classified in two groups: the study group (n = 23) included women with very high parity over 45 years of age (age > 45 and > or = 10 previous live births), and a control group (n = 38) included women with high parity between 40-45 years of age (between 40-45 years and 5-9 previous live births). Hypertensive disorders complicating pregnancy, preterm labor, breech presentation, cesarean section ratio, mean APGAR scores, birthweight, fetal sex, fetal macrosomia, and early neonatal death were compared within groups. Six (26%) patients in the study group and 12 (31.5%) patients in the control group had hypertensive disorders of pregnancies (p > 0.05). Twelve (52.1%) patients in the study group and 22 (57.8%) patients in the control group had preterm labor (p > 0.05). One (4%) patient in the study group and two (5.2%) patients in the control group had breech presentation during delivery (p > 00.5). Twelve (52.1%) patients in the study group and 21 (55.2%) patients in the control group had cesarean operations (p > 0.05). Mean APGAR scores (at 1 min and 5 min), mean birthweight, fetal sex ratio, fetal macrosomia ratio, and early neonatal death ratio due to prematurity were not statistically significant in the study group as compared with the control group. It is generally assumed that women with advanced age have an increased risk for complications during pregnancy. However, prospective population-based studies do not exist and available publications give conflicting views. Based on our results, we hypothesized that cases aged 45 or over with very high parity are not always related with adverse maternal and fetal outcomes.

Skills training in simulation laboratories is becoming increasingly common. However, the educational benefit of these laboratories remains unclear. This study examined whether such training enables better performance on the simultaneous execution of technical skill and knowledge retention. Twenty-four novice trainees completed the elliptical excision on baseline testing. Following baseline testing twelve of the novices completed a technical practice (simulation training group) session, while the other twelve did not (control group). One week later, all participants returned for dual-task follow up testing in which they performed the excision while listening to a didactic lesson on the staging and treatment of cutaneous melanoma. The dual-tasking during the post test was standardized, whereby excision sutures 3 and 5 were performed alone (single), and sutures 4 and 6 were performed concurrently with the didactic lecture (dual). Seven additional trainees also participated as controls that were randomized to listen to the didactic lesson alone (knowledge retention alone group). Knowledge retention was assessed by a multiple choice questionnaire (MCQ). Technical performance was evaluated with computer and expert-based measures. Time to complete the performance improved among both groups completing the elliptical excision on follow-up testing (p<0.01). The simulation training group demonstrated superior hand motion performance on simultaneous didactic lesson testing (p<0.01). Novices from the no-training group performed statistically worse while suturing concurrently with the didactic lesson (p<0.01). The pretraining of novices in surgical skills laboratories leads to improved technical performance during periods of increased attention demands.

The transfer of learning process: From an elementary science methods course to classroom instruction

NASA Astrophysics Data System (ADS)

Carter, Nina Leann

The purpose of this qualitative multiple-case study was to explore the transfer of learning process in student teachers. This was carried out by focusing on information learned from an elementary science methods and how it was transferred into classroom instruction during student teaching. Participants were a purposeful sampling of twelve elementary education student teachers attending a public university in north Mississippi. Factors that impacted the transfer of learning during lesson planning and implementation were sought. The process of planning and implementing a ten-day science instructional unit during student teaching was examined through lesson plan documentation, in-depth individual interviews, and two focus group interviews. Narratives were created to describe the participants' experiences as well as how they plan for instruction and consider science pedagogical content knowledge (PCK). Categories and themes were then used to build explanations applying to the research questions. The themes identified were Understanding of Science PCK, Minimalism, Consistency in the Teacher Education Program, and Emphasis on Science Content. The data suggested that the participants lack in their understanding of science PCK, took a minimalistic approach to incorporating science into their ten-day instructional units, experienced inconsistencies in the teacher education program, and encountered a lack of emphasis on science content in their field experience placements. The themes assisted in recognizing areas in the elementary science methods courses, student teaching field placements, and university supervision in need of modification.

The Experiences of Tobacco Use among South-Western Taiwanese Adolescent Males

Most smokers start young. Initiation of cigarette smoking at an earlier age leads to more life-years for tobacco use, makes quitting harder, and increases the risk of serious health consequences. Despite these challenges, research focusing on smoking behavior among adolescent boys in Taiwan is rare. Although the Taiwanese government enacted the Tobacco Hazards Prevention Act in 2009, aimed at prevention and reducing the rate of smoking, the percentage of high school students who smoke has continued to increase. In 2006, 7.5% of adolescent boys engaged in smoking. By 2012 the rate had increased to 24.6%. This paper explores the experiences that contribute to adolescent Taiwanese boys making the decision to smoke. A phenomenological approach to inquiry was used as the philosophical foundations for this study with twelve adolescent boys who engaged in smoking behaviors. Data was gathered through two face-to-face semi-structured interviews and a focus group. Data analysis was performed using Colaizzi’s analysis method. Findings indicated that decisions to begin smoking were motivated by curiosity and as a means of establishing friendships while decisions to continue smoking were linked to the addictive nature of smoking and as a means of coping with stress and passing the time. The findings can be used to inform the prevention of tobacco use and to reduce the high smoking rates among adolescent boys. PMID:26343695

The present study was designed to fill a gap in the literature on attentional focus and sports performance. Specifically, in contrast to most previous studies in which an external focus was directed at an implement, we used a gymnastics skill that did not involve the use of an implement. Furthermore, while most studies used only outcome measures of performance, we also assessed movement quality. Twelve-year-old gymnasts performed a maximum vertical jump with a 180-degree turn while airborne, with their hands crossing in front of their chest during the turn under three different focus conditions. Under the external focus condition, participants were asked to focus on the direction in which a tape marker, which was attached to their chest, was pointing after the turn. Under the internal focus condition, they were asked to focus on the direction in which their hands were pointing after the turn. Under the control condition, no focus instructions were given. The external focus condition resulted in both superior movement form and greater jump height than did the other two conditions, which produced comparable results. The present findings show that, similar to other tasks, the performance of form-based skills can be enhanced relatively easily by appropriate external focus instructions.

To examine the relationship between the composite Functional Movement Screen (FMS) score and performers' spine and frontal plane knee motion. Examined the spine and frontal plane knee motion exhibited by performers who received high (>14) and low (<14) composite FMS scores. Participants' body motions were quantified while they performed the FMS. Biomechanics laboratory. Twelve men who received composite FMS scores greater than 14 were assigned to a high-scoring group. Twelve age-, height- and weight-matched men with FMS scores below 14 were assigned to a low-scoring group. Composite FMS scores and peak lumbar spine flexion/extension, lateral bend and axial twist, and left and right frontal plane knee motion. Significant differences (p < 0.05) and large effect sizes (>0.8) were noted between the high- and low-scoring groups when performing the FMS tasks; high-scorers employed less spine and frontal plane knee motion. Substantial variation was also observed amongst participants. Participants with high composite FMS scores exhibited less spine and frontal plane knee motion while performing the FMS in comparison to their low-scoring counterparts. However, because substantial variation was observed amongst performers, the FMS may not provide the specificity needed for individualized injury risk assessment and exercise prescription.

The unmet demand for kidney transplantation has generated intense controversy about introducing incentives for living kidney donors to increase donation rates. Such debates may affect public perception and acceptance of living kidney donation. This study aims to describe the range and depth of public opinion on financial reimbursement, compensation, and incentives for living kidney donors. Twelve focus groups were conducted with 113 participants recruited from the general public in three Australian states in February 2013. Thematic analysis was used to analyze the transcripts. Five themes were identified: creating ethical impasses (commodification of the body, quandary of kidney valuation, pushing moral boundaries), corrupting motivations (exposing the vulnerable, inevitable abuse, supplanting altruism), determining justifiable risk (compromising kidney quality, undue harm, accepting a confined risk, trusting protective mechanisms, right to autonomy), driving access (urgency of organ shortage, minimizing disadvantage, guaranteeing cost-efficiency, providing impetus, counteracting black markets), and honoring donor deservingness (fairness and reason, reassurance and rewards, merited recompense). Reimbursement and justifiable recompense are considered by the Australian public as a legitimate way of supporting donors and reducing disadvantage. Financial payment beyond reimbursement is regarded as morally reprehensible, with the potential for exploitative commercialism. Some contend that regulated compensation could be a defensible strategy to increased donation rates provided that mechanisms are in place to protect donors. The perceived threat to community values of human dignity, goodwill, and fairness suggests that there could be strong public resistance to any form of financial inducements for living kidney donors. Policy priorities addressing the removal of disincentives may be more acceptable to the public. Copyright © 2015 by the American Society of Nephrology.

Tuberculosis infection among health care workers is capable of worsening the existing health human resource problems of low--and middle-income countries. Tuberculosis infection control is often weakly implemented in these parts of the world therefore, understanding the reasons for poor implementation of tuberculosis infection control guidelines are important. This study was aimed at assessing tuberculosis infection control practices and barriers to its implementation in Ikeja, Nigeria. A cross-sectional study in 20 tuberculosis care facilities (16 public and 4 private) in Ikeja, Lagos was conducted. The study included a facility survey to assess the availability of tuberculosis infection control guidelines, the adequacy of facilities to prevent transmission of tuberculosis and observations of practices to assess the implementation of tuberculosis infection control guidelines. Four focus group discussions were carried out to highlight HCWs' perceptions on tuberculosis infection control guidelines and barriers to its implementation. The observational study showed that none of the clinics had a tuberculosis infection control plan. No clinic was consistently screening patients for cough. Twelve facilities (60%) consistently provided masks to patients who were coughing. Ventilation in the waiting areas was assessed to be adequate in 60% of the clinics while four clinics (20%) possessed N-95 respirators. Findings from the focus group discussions showed weak managerial support, poor funding, under-staffing, lack of space and not wanting to be seen as stigmatizing against tuberculosis patients as barriers that hindered the implementation of TB infection control measures. Tuberculosis infection control measures were not adequately implemented in health facilities in Ikeja, Nigeria. A multi-pronged approach is required to address the identified barriers to the implementation of tuberculosis infection control guidelines.

Preparing the nursing workforce to meet the challenges of an ageing population is a priority for many countries. The development of an Older Person's Nurse Fellowship (OPNF) programme for senior clinical nurses is an important innovation. This article describes the philosophical development, delivery and early evaluation of the OPNF. In 2014, Health Education England funded 24 senior clinical nurses to participate in the OPNF. The Fellowship was designed to build clinical leadership and innovation capability and develop a network of nurses to influence local and national strategy for older people's care. The Fellows selected were drawn from mental health (n=4), community/primary care (n=9) and acute care (n=11). The twelve month programme consisted of two Masters-level modules, delivered through study days and e-learning. The first cohort (n=12) commenced the course in November 2014 with a module designed to enhance clinical knowledge and skills. Evaluation data were collected from the first cohort using anonymous surveys (n=11) and focus group interviews (n=9). Descriptive statistics are presented for the quantitative data and common themes are described in the qualitative data. The overall satisfaction with the clinical module was high with a median score of 18/20 (range 17-20). Topics such as comprehensive geriatric assessment, frailty, pharmacology and cognitive assessment were regarded as highly relevant and most likely to result in a change to clinical practice. In the focus group interviews students discussed their learning experience in terms of: module specificity, peer-to-peer learning and using the OPNF as leverage for change. The OPNF is a timely innovation and a positive commitment to developing an academic pathway for senior nurses. It marks an important step in the future development of the older person's nursing workforce. Copyright © 2016 Elsevier Ltd. All rights reserved.

The kidney failure risk equation (KFRE) provides an estimate of risk of progression to kidney failure, and may guide clinical care. We aimed to describe patient, family, and health care provider's perspectives of the perceived benefits and challenges of using a risk-based approach to guide care delivery for patients with advanced chronic kidney disease (CKD), and refine implementation based on their input. We used qualitative methodology to explore perceived benefits and challenges of implementing a risk-based approach (using the KFRE) to determine eligibility for multidisciplinary CKD care in Southern Alberta. We obtained perspectives from patients and families through focus groups, as well as input from health care providers through interviews and open-ended responses from an online survey. Twelve patients/family members participated in 2 focus groups, 16 health care providers participated in an interview, and 40 health care providers responded to the survey. Overall, participants felt that a KFRE-based approach had the potential to improve efficiency of the clinics by targeting care to patients at highest risk of kidney failure; however, they also expressed concerns about the impact of loss of services for lower risk individuals. Participants also articulated concerns about a perceived lack of capacity for adequate CKD patient care in the community. Our implementation strategy was modified as a result of participants' feedback. We identified benefits and challenges to implementation of a risk-based approach to guide care of patients with advanced CKD. Based on these results, our implementation strategy has been modified by removing the category of referral back to primary care alone, and instead having that decision made jointly by nephrologists and patients among low-risk patients.

To identify practical examples of barriers and possible solutions to improve general practice integration with other health service providers. Twelve focus groups, including one conducted by teleconference, were held across Australia with GPs and non GP primary health service providers between May and September, 1996. Focus groups were embedded within concept mapping sessions, which were used to conceptually explore the meaning of integration in general practice. Data coding, organising and analysis were based on the techniques documented by Huberman and Miles. Barriers to integration were perceived to be principally due to the role and territory disputes between the different levels of government and their services, the manner in which the GP's role is currently defined, and the system of GP remuneration. Suggestions on ways to improve integration involved two types of strategies. The first involves initiatives implemented 'top down' through major government reform to service structures, including the expansion of the role of divisions of general practice, and structural changes to the GP remuneration systems. The second type of strategy suggested involves initiatives implemented from the 'bottom up' involving services such as hospitals (e.g. additional GP liaison positions) and the use of information technology to link services and share appropriate patient data. The findings support the need for further research and evaluation of initiatives aimed at achieving general practice integration at a systems level. There is little evidence to suggest which types of initiatives improve integration. However, general practice has been placed in the centre of the health care debate and is likely to remain central to the success of such initiatives. Clarification of the future role and authority of general practice will therefore be required if such integrative strategies are to be successful at a wider health system level.

Supersonic sled tests on the Sandia 1524-m (5000-ft) track generate sonic booms of sufficient intensity to allow some airblast measurements at distance scales not obtained from wind tunnel or flight tests. During acceleration, an emitted curved boom wave propagates to a caustic, or focus. Detailed measurements around these caustics may help to clarify the overpressure magnification which can occur from real aircraft operations. Six fixed pressure gages have been operated to document the general noise field, and a mobile array of twelve gages.

“I have to do what I believe”: Sudanese women’s beliefs and resistance to hegemonic practices at home and during experiences of maternity care in Canada

PubMed Central

2013-01-01

Background Evidence suggests that immigrant women having different ethnocultural backgrounds than those dominant in the host country have difficulty during their access to and reception of maternity care services, but little knowledge exists on how factors such as ethnic group and cultural beliefs intersect and influence health care access and outcomes. Amongst immigrant populations in Canada, refugee women are one of the most vulnerable groups and pregnant women with immediate needs for health care services may be at higher risk of health problems. This paper describes findings from the qualitative dimension of a mixed-methodological study. Methods A focused ethnographic approach was conducted in 2010 with Sudanese women living in an urban Canadian city. Focus group interviews were conducted to map out the experiences of these women in maternity care, particularly with respect to the challenges faced when attempting to use health care services. Results Twelve women (mean age 36.6 yrs) having experience using maternity services in Canada within the past two years participated. The findings revealed that there are many beliefs that impact upon behaviours and perceptions during the perinatal period. Traditionally, the women mostly avoid anything that they believe could harm themselves or their babies. Pregnancy and delivery were strongly believed to be natural events without need for special attention or intervention. Furthermore, the sub-Saharan culture supports the dominance of the family by males and the ideology of patriarchy. Pregnancy and birth are events reflecting a certain empowerment for women, and the women tend to exert control in ways that may or may not be respected by their husbands. Individual choices are often made to foster self and outward-perceptions of managing one’s affairs with strength. Conclusion In today’s multicultural society there is a strong need to avert misunderstandings, and perhaps harm, through facilitating cultural awareness and competency of care rather than misinterpretations of resistance to care.

Although end-of-life care preferences vary across racial/ethnic groups, little is known about how cultural values affect end-of-life care preferences among South Asian immigrants and their offspring in the US. To examine the perspectives of first- and second-generation South Asians living in the US regarding end-of-life care. Focus group study. Discussions explored participant preferences and experiences with family members facing the end of life. Twelve first-generation and 11 second-generation self-identified Asian Indians living in the mid-Atlantic region. Content analysis of focus group transcripts. First-generation participants ranged in age from 41 to 76 years and were evenly split by gender. Second-generation participants ranged in age from 23 to 36 years and included seven women and four men. All participants were highly educated, and two thirds were either studying or working in a health care field. All but two subjects were Hindu. Several themes emerged that highlighted cultural differences and challenges for this population in the context of end-of-life care: attitudes toward death and suffering; family duty; and preferences for information disclosure and decision making. Participants described cultural challenges due to the evolution of traditional roles, lack of explicit discussion between patients and family members about preferences and care expectations, and a tension between wanting to meet traditional expectations and the challenges in doing so given US social realities. Traditional cultural values, such as duty to family, greatly influenced end-of-life care preferences and retained importance across generations. Clinicians caring for Asian Indian patients at the end of life may be better able to assess care preferences after exploring the complex interplay between traditional expectations and specific social realities for each patient. Particular attention should be given to attitudes toward death and suffering, family duty, and preferences for information disclosure and decision making.

Configuring The REU Experience To Maximize Student Collaboration

The New Mexico Tech NSF-funded REU Program, Interdisciplinary Science for the Environment (ISE), hosted six cohorts of students between 2005 and 2010. The program ran for eight weeks during the first cycle and nine weeks during the second cycle, bringing in an average of twelve student participants per year. Students were provided with a stipend, food allowance, travel from home to New Mexico Tech, and free campus housing. The program sponsored weekend group field trips to scientific, environmental, and cultural sites of significance in New Mexico. For the second cycle, the ISE shared some programmatic elements with the New Mexico EPSCoR Undergraduate Research Opportunities Program (UROP). The majority of the research projects focused on the geosciences, with interdepartmental participation from researchers in earth science, hydrology, chemistry, environmental science, and biology. The ISE adopted a non-traditional approach to matching student participants with research projects and faculty mentors. Students were selected from different disciplines to work together in pairs on each project. This model provided the students with a peer collaborator in addition to the guidance of their faculty mentors and support from graduate students associated with the different projects. The focus on cohort, both within the individual research projects and each year's group, enabled and enhanced the students' critical thinking, problem-solving and teamwork skills. Students would routinely seek out the advice of their peers when they hit a roadblock in their research. This collaboration also occurred across the boundaries of the ISE and UROP cohorts. Long-term follow up has shown that a significant number of the student participants have continued on to graduate school. Students credit the program with developing their capacity to work on complex problems in an interdisciplinary group environment. Additionally, many students have continued contact with their research partners, faculty mentors and other members of their REU cohort.

Background Birth preparedness and complication readiness (BP/CR) strategies are aimed at reducing delays in seeking, reaching, and receiving care. Counselling on birth preparedness is provided during antenatal care visits. However, it is not clear why birth preparedness messages do not translate to utilisation of facility delivery. This study explores the perceptions, experiences, and challenges the community faces on BP/CR. Design A qualitative study design using Focused Group Discussions was conducted. Twelve focus group discussions were held with four separate groups: young men and women and older men and women in a rural community in Tanzania. Qualitative content analysis was used to analyse the data. Results The community members expressed a perceived need to prepare for childbirth. They were aware of the importance to attend the antenatal clinics, relied on family support for practical and financial preparations such as saving money for costs related to delivery, moving closer to the nearest hospital, and also to use traditional herbs, in favour of a positive outcome. Community recognised that pregnancy and childbirth complications are preferably treated at hospital. Facility delivery was preferred; however, certain factors including stigma on unmarried women and transportation were identified as hindering birth preparedness and hence utilisation of skilled care. Challenges were related to the consequences of poverty, though the maternal health care should be free, they perceived difficulties due to informal user fees. Conclusions This study revealed community perceptions that were in favour of using skilled care in BP/CR. However, issues related to inability to prepare in advance hinder the realisation of the intention to use skilled care. It is important to innovate how the community reinforces BP/CR, such as using insurance schemes, using community health funds, and providing information on other birth preparedness messages via community health workers.

Recent attempts to model the addiction process in rodents have focused on cocaine self-administration procedures that provide extended daily access. Such procedures produce a characteristic loading phase during which blood levels rapidly rise and then are maintained within an elevated range for the duration of the session. The present experiments tested the hypothesis that multiple fast-rising spikes in cocaine levels contribute to the addiction process more robustly than constant, maintained drug levels. Here, we compared the effects of various cocaine self-administration procedures that produced very different patterns of drug intake and drug dynamics on Pmax, a behavioral economic measure of the motivation to self-administer drug. Two groups received intermittent access (IntA) to cocaine during daily 6-h sessions. Access was limited to twelve 5-min trials that alternated with 25-min timeout periods, using either a hold-down procedure or a fixed ratio 1 (FR1). Cocaine levels could not be maintained with this procedure; instead the animals experienced 12 fast-rising spikes in cocaine levels each day. The IntA groups were compared with groups given 6-h FR1 long access and 2-h short access sessions and two other control groups. Here, we report that cocaine self-administration procedures resulting in repeatedly spiking drug levels produce more robust increases in Pmax than procedures resulting in maintained high levels of cocaine. These results suggest that rapid spiking of brain-cocaine levels is sufficient to increase the motivation to self-administer cocaine.

To study the attitudes, concerns, perceived impact, coping strategies, knowledge on avian influenza (AI) and personal protection measures, and institutional and personal preparedness for AI among all Indonesian primary healthcare workers (PHW). Questionnaire survey of PHW from four public primary healthcare clinics in South Jakarta (n = 333), with Singaporean PHW from 18 such clinics as controls (n = 1321). Twelve focus group discussions with 51 South Jakarta PHW were also conducted. Quantitative and qualitative data were analysed separately with statistical and thematic analysis, respectively, then combined. South Jakarta PHW had positive attitudes but major concerns about contracting AI, difficulties in diagnosing human AI and inadequacy of personal protection provided. South Jakarta PHW are less knowledgeable about AI and use of personal protection equipment, and reported poorer awareness, availability and participation in AI preparation activities. Only 3% of South Jakarta PHW received influenza vaccination in the preceding 6 months and few felt prepared for AI. South Jakarta primary healthcare workers are not well prepared for avian influenza. There is an urgent need to build their primary healthcare capacity to protect them and contain this global health threat.

2014-01-01

Objective As long-term results of conservative treatment for obesity are discouraging, bariatric surgery is becoming a treatment option for extremely obese adolescents. However, mental and behavioral problems need to be respected when treating this vulnerable target group. Methods A detailed systematic literature review on pre- and post-operative depressive, anxiety and eating disorder symptoms of adolescent patients was performed in PsychINFO, PubMed and Medline electronic databases. Results Twelve studies met the inclusion criteria. Although strength of evidence was limited, results suggested that pre-operatively a third of adolescents suffered from moderate to severe depressive disorder symptoms and a quarter from anxiety disorder symptoms, while a substantial number showed eating disorder symptoms. Post-operatively, levels of depressive disorder symptoms significantly improved. Original articles on outcomes of eating and anxiety disorder symptoms after weight loss surgery were not found. Conclusions Further attention is needed on consistent clinical assessment of mental health disturbances and their consecutive treatment in adolescents. Future research should also focus on psychological and psychosocial predictors of weight loss after bariatric surgery. PMID:25059420

To describe perceptions and beliefs about electronic cigarette (e-cigarette) use during pregnancy among pregnant and newly postpartum women. An exploratory, qualitative descriptive study. University-affiliated prenatal clinics. Twelve pregnant or recently postpartum women who reported use of tobacco and electronic cigarettes. Semistructured focus groups were audio recorded and professionally transcribed. The transcripts were coded to consensus and analyzed with MAXQDA software (version 11) using content analysis. Four overarching themes emerged: (a) Attraction to E-Cigarettes as a Harm Reduction Strategy, (b) Uncertainty Regarding the Health Effects of E-Cigarettes; (c) Ambivalence Regarding Novel Product Characteristics; and (d) Behaviors Reflected Dual Use and Often Complete Relapse to Traditional Cigarettes. Pregnant women are initially attracted to e-cigarettes as a harm reduction strategy, but they often return to traditional cigarettes in the postpartum period. Nurses should counsel pregnant women on the adverse effects of fetal exposure to nicotine. Evidence-based nursing interventions are needed to prevent relapse during the postpartum period.

Background The United States is one of the last countries to change from ICD-9-CM to ICD-10-CM/PCS. The compliance date for implementation of ICD-10-CM/PCS is expected to fall on October 1, 2015. Objectives Evaluate physicians’ perceptions on the change from ICD-9-CM to ICD-10-CM/PCS and its effect on their practice, determine how HIM professionals can assist in this transition, and assess what resources are needed to aid in the transition. Results Twenty physicians were asked to participate in one of three focus groups. Twelve physicians (60 percent) agreed to participate. Top concerns included electronic health record software readiness, increase in documentation specificity and time, ability of healthcare professionals to learn a new language, and inadequacy of current training methods and content. Conclusion Physicians expressed that advantages of ICD-10-CM/PCS were effective data analytics and complexity of patient cases with more specific codes. Health information management professionals were touted as needed during the transition to create simple, clear specialty guides and crosswalks as well as education and training tools specific for physicians.

To explore in what way emotional communication can enhance the memory of people with (different types of) dementia. Relevant studies published after 2000 were searched using the terms: dementia, positive, words, communication, recall, and memory. Papers were included that reported results of studies with people with dementia that investigated memory effects of communication with either an emotionally valent content or context. Twelve papers grouped under four prevailing themes (pictures, facial emotions, stories and words) are described. The studies provide mixed results: in some studies negative emotional information enhances memory in older people with dementia, in other studies positive emotional information is helpful or hardly any effect is found. Emotional communication seems to enhance memory in people with dementia. None of the studies described focused on the association between personally relevant, emotionally valent information and memory, so further research is needed. Caregivers in dementia care should realize that 1) the information they provide might carry an emotional valence, and 2) this valence might influence the extent to which people with dementia remember information.

Evaluating the cost effectiveness and cost utility of an integrated care intervention and participatory workplace intervention for workers with rheumatoid arthritis (RA) to improve their work productivity. Twelve month follow-up economic evaluation alongside a randomized controlled trial (RCT) within specialized rheumatology treatment centers. Adults diagnosed with RA between 18-64 years, in a paid job for at least eight hours per week, experiencing minor difficulties in work functioning were randomized to the intervention (n = 75) or the care-as-usual (CAU) group (n = 75). Effect outcomes were productivity and quality of life (QALYs). Costs associated with healthcare, patient and family, productivity, and intervention were calculated from a societal perspective. Cost effectiveness and cost utility were assessed to indicate the incremental costs and benefits per additional unit of effect. Subgroup and sensitivity analyses evaluated the robustness of the findings. At-work productivity loss was about 4.6 hours in the intervention group and 3.5 hours in the care as usual (CAU) group per two weeks. Differences in QALY were negligible; 0.77 for the CAU group and 0.74 for the intervention group. In total, average costs after twelve months follow-up were highest in the intervention group (€7,437.76) compared to the CAU group (€5,758.23). The cost-effectiveness and cost-utility analyses show that the intervention was less effective and (often) more expensive when compared to CAU. Sensitivity analyses supported these findings. The integrated care intervention and participatory workplace intervention for workers with RA provides gains neither in productivity at the workplace nor in quality of life. These results do not justify the additional costs.

Dendrimers are nano-materials with perfectly defined structure and size, and multivalency properties that confer substantial advantages for biomedical applications. Previous work has shown that phosphorus-based polyphosphorhydrazone (PPH) dendrimers capped with azabisphosphonate (ABP) end groups have immuno-modulatory and anti-inflammatory properties leading to efficient therapeutic control of inflammatory diseases in animal models. These properties are mainly prompted through activation of monocytes. Here, we disclose new insights into the molecular mechanisms underlying the anti-inflammatory activation of human monocytes by ABP-capped PPH dendrimers. Following an interdisciplinary approach, we have characterized the physicochemical and biological behavior of the lead ABP dendrimer with model and cell membranes, and compared this experimental set of data to predictive computational modelling studies. The behavior of the ABP dendrimer was compared to the one of an isosteric analog dendrimer capped with twelve azabiscarboxylate (ABC) end groups instead of twelve ABP end groups. The ABC dendrimer displayed no biological activity on human monocytes, therefore it was considered as a negative control. In detail, we show that the ABP dendrimer can bind both non-specifically and specifically to the membrane of human monocytes. The specific binding leads to the internalization of the ABP dendrimer by human monocytes. On the contrary, the ABC dendrimer only interacts non-specifically with human monocytes and is not internalized. These data indicate that the bioactive ABP dendrimer is recognized by specific receptor(s) at the surface of human monocytes.Dendrimers are nano-materials with perfectly defined structure and size, and multivalency properties that confer substantial advantages for biomedical applications.

Although autologous nerve grafting is the gold standard treatment of peripheral nerve injuries, several alternative methods have been developed, including nerve conduits that use supportive cells. However, the seeding efficacy and viability of supportive cells injected in nerve grafts remain unclear. Here, we focused on a novel completely biological, tissue-engineered, scaffold-free conduit. We developed six scaffold-free conduits from human normal dermal fibroblasts using a Bio 3D Printer. Twelve adult male rats with immune deficiency underwent mid-thigh-level transection of the right sciatic nerve. The resulting 5-mm nerve gap was bridged using 8-mm Bio 3D conduits (Bio 3D group, n = 6) and silicone tube (silicone group, n = 6). Several assessments were conducted to examine nerve regeneration eight weeks post-surgery. Kinematic analysis revealed that the toe angle to the metatarsal bone at the final segment of the swing phase was significantly higher in the Bio 3D group than the silicone group (-35.78 ± 10.68 versus -62.48 ± 6.15, respectively; p < 0.01). Electrophysiological studies revealed significantly higher compound muscle action potential in the Bio 3D group than the silicone group (53.60 ± 26.36% versus 2.93 ± 1.84%; p < 0.01). Histological and morphological studies revealed neural cell expression in all regions of the regenerated nerves and the presence of many well-myelinated axons in the Bio 3D group. The wet muscle weight of the tibialis anterior muscle was significantly higher in the Bio 3D group than the silicone group (0.544 ± 0.063 versus 0.396 ± 0.031, respectively; p < 0.01). We confirmed that scaffold-free Bio 3D conduits composed entirely of fibroblast cells promote nerve regeneration in a rat sciatic nerve model.

A soft X-ray glancing incidence telescope mirror and a group of twelve optical flat samples were used to study the scattering of X-rays. The mirror was made of Kanigen coated beryllium and the images produced were severely limited by scattering of X-rays. The best resolution attained was about fifteen arc seconds. The telescope efficiency was found to be 0.0006. The X-ray beam reflected from the twelve optical flat samples was analyzed by means of a long vacuum system of special design for these tests. The scattering then decreased with increasing angle of incidence until a critical angle was passed. At larger angles the scattering increased again. The samples all scattered more at 44 A than at 8 A. Metal samples were found to have about the same scattering at 44 A but greater scattering at 8 A than glass samples.

This study aimed to evaluate the effectiveness of the national food distribution program on the growth and nutritional status of malnourished or growth-retarded children in 2 provinces of Iran. A quasi-experimental design was used for the effectiveness evaluation. Qualitative data were gathered to explain the results. An intervention group consisted of 362 children aged 6-72 months who were under coverage of the program. These children received monthly food as foodstuff, food vouchers, or cash. A comparison group included 409 children aged 6-72 months who were selected from those covered by the Primary Health Care system. Children anthropometric indices were measured at the baseline and also 6 months later. Twelve focus group discussions were held with mothers who had at least 1 child under the coverage of the program. At the end of the study, the mean weight-for-age Z scores, height-for-age Z scores, and weight-for-height Z scores increased compared with the baselines in both groups (p < .001). The differences between 2 groups in weight-for-age Z scores, height-for-age Z scores, and weight-for-height Z scores were not significant at the end of the study (p = .62, p = .91, and p = .94, respectively). According to the mothers' reports, factors affected the program outcome, that is, children anthropometric indices were low income, intrahousehold food sharing, irregular distribution, quantity and quality of the distributed food, and insufficient training. Providing foods for the malnourished children living in low-income families helped to prevent a worsening of their nutritional status; however, it has not been effective in solving the problem, probably due to the weak implementation and lack of empowerment strategies. © 2018 John Wiley & Sons Ltd.

Smokers' and ex-smokers' understanding of electronic cigarettes: a qualitative study.

Rooke, Catriona; Cunningham-Burley, Sarah; Amos, Amanda

2016-04-01

To explore among a diverse range of smokers and recent ex-smokers, particularly those from disadvantaged groups, how nicotine-containing products, particularly electronic cigarettes (e-cigarettes), are understood and experienced. Qualitative study of 64 smokers and ex-smokers in Central Scotland. Twelve focus groups and 11 individual interviews were carried out with a range of purposively selected groups. Nicotine replacement therapies and e-cigarettes were regarded as being very different products. Nicotine replacement therapies were viewed as medical products for smokers who want to quit, while e-cigarettes emerged as an ambiguous product whose meanings are still being negotiated. Participants' attitudes and intentions about smoking and quitting were especially important in shaping their understanding of these products. Four main interpretations of e-cigarettes were identified: a more satisfying replacement for smoking, an ambiguous but potentially useful device, a less desirable cigarette and a threat to smoking cessation. The acceptability of continued nicotine addiction and the similarity of e-cigarettes to conventional cigarettes were central themes on which participants held conflicting views. There was considerable uncertainty among participants around the constituents and safety of e-cigarettes. Different groups of smokers bring diverse expectations, requirements and concerns to their evaluations and therefore to the potential use of nicotine-containing products. The ambiguity around e-cigarettes in public health debates and medical practice is reflected in the positions and concerns of smokers. There is a need for both clear, up-to-date trustworthy information about their benefits and risks, and stronger regulation. Published by the BMJ Publishing Group Limited.

To assess whether the volume of callosal hyperintensities in the genu and splenium of older adults with mobility impairment is differentially associated with the degree of gain in gait speed after 2 types of gait interventions. Single-blind randomized controlled trial of 2 types of gait exercises in older adults. Research center in an academic institution. Ambulatory adults (N=44) aged ≥65 years with a slow and variable gait. Twelve-week physical therapist-guided trial of a conventional walking, endurance, balance, and strength (WEBS) intervention (n=20) versus a timing and coordination of gait (TC) intervention (n=22). Gain in gait speed after the intervention and its relation to callosal hyperintensities in the genu and splenium of the corpus callosum. Gait speed improved in both the WEBS group (mean change, 0.16m/s) and the TC group (mean change, 0.21m/s; both P<.05). The volume of white matter hypertintensities (WMHs) in the genu was differentially associated with gait speed gain (group × genual WMH interaction, P=.05). Greater genual WMH volume was related to a smaller gait speed gain in the WEBS group (P=.01) but not in the TC (P=.10) group. Splenial WMH volume was not differentially associated with gait speed gain (interaction, P=.90). Callosal hyperintensities differentially influence gait speed gain by the type of gait rehabilitation. Mobility impaired older adults with genual hyperintensities may benefit from a rehabilitation program focused on motor skill learning rather than on strength and endurance training.

The reduction of pathogenic microorganisms in supragingival plaque is one of the principal factors in caries prevention and control. A large number of microorganisms have been reported to be inactivated in vitro by photodynamic therapy (PDT). The purpose of this study was to develop a rat model to investigate the effects of PDT on bacterial reduction in induced dental caries. Twenty four rats were orally inoculated with Streptococcus mutans cells (ATCC 25175) for three consecutive days. The animals were fed with a cariogenic diet and water with 10% of sucrose ad libitum, during all experimental period. Caries lesion formation was confirmed by Optical Coherence Tomography (OCT) 5 days after the beginning of the experiment. Then, the animals were randomly divided into two groups: Control Group: twelve animals were untreated by either light or photosensitizer; and PDT Group: twelve animals were treated with 100μM of methylene blue for 5min and irradiated by a Light Emitting Diode (LED) at λ = 640+/-30nm, fluence of 172J/cm2, output power of 240mW, and exposure time of 3min. Microbiological samples were collected before, immediately after, 3, 7 and 10 days after treatment and the number of total microaerophiles was counted. OCT images showed areas of enamel demineralization on rat molars. Microbiological analysis showed a significant bacterial reduction after PDT. Furthermore, the number of total microaerophiles in PDT group remained lower than control group until 10 days posttreatment. These findings suggest that PDT could be an alternative approach to reduce bacteria in dental caries.

To evaluate the clinical effectiveness of a self-managed single exercise programme versus usual physiotherapy treatment for rotator cuff tendinopathy. Multi-centre pragmatic unblinded parallel group randomised controlled trial. UK National Health Service. Patients with a clinical diagnosis of rotator cuff tendinopathy. The intervention was a programme of self-managed exercise prescribed by a physiotherapist in relation to the most symptomatic shoulder movement. The control group received usual physiotherapy treatment. The primary outcome measure was the Shoulder Pain & Disability Index (SPADI) at three months. Secondary outcomes included the SPADI at six and twelve months. A total of 86 patients (self-managed loaded exercise n=42; usual physiotherapy n=44) were randomised. Twenty-six patients were excluded from the analysis because of lack of primary outcome data at the 3 months follow-up, leaving 60 (n=27; n=33) patients for intention to treat analysis. For the primary outcome, the mean SPADI score at three months was 32.4 (SD 20.2) for the self-managed group, and 30.7 (SD 19.7) for the usual physiotherapy treatment group; mean difference adjusted for baseline score: 3.2 (95% Confidence interval -6.0 to +12.4 P = 0.49).By six and twelve months there remained no significant difference between the groups. This study does not provide sufficient evidence of superiority of one intervention over the other in the short-, mid- or long-term and hence a self-management programme based around a single exercise appears comparable to usual physiotherapy treatment. © The Author(s) 2015.

2008-06-01

Purpose: To determine whether hippocampal neurons are lost 12 months after middle-aged rats received a fractionated course of whole-brain irradiation (WBI) that is expected to be biologically equivalent to the regimens used clinically in the treatment of brain tumors. Methods and Materials: Twelve-month-old Fischer 344 X Brown Norway male rats were divided into WBI and control (CON) groups (n = 6 per group). Anesthetized WBI rats received 45 Gy of {sup 137}Cs {gamma} rays delivered as 9 5-Gy fractions twice per week for 4.5 weeks. Control rats were anesthetized but not irradiated. Twelve months after WBI completion, all rats weremore » anesthetized and perfused with paraformaldehyde, and hippocampal sections were immunostained with the neuron-specific antibody NeuN. Using unbiased stereology, total neuron number and the volume of the neuronal and neuropil layers were determined in the dentate gyrus, CA3, and CA1 subregions of hippocampus. Results: No differences in tissue integrity or neuron distribution were observed between the WBI and CON groups. Moreover, quantitative analysis demonstrated that neither total neuron number nor the volume of neuronal or neuropil layers differed between the two groups for any subregion. Conclusions: Impairment on a hippocampal-dependent learning and memory test occurs 1 year after fractionated WBI at middle age. The same WBI regimen, however, does not lead to a loss of neurons or a reduction in the volume of hippocampus.« less

Symptoms of hyperthyroidism manifest mainly as changes in the nervous and metabolic systems. Whether P2X receptors (ionotropic ATP purinergic receptors, including P2X3 receptor and P2X7 receptor) are involved in the alterations of these disorders still remains unclear. Thus, this study aimed to assess the association of hyperthyroidism with the expression of P2X3 and P2X7 receptors and the concentrations of ATP in blood leukocytes and catecholamine. Twelve healthy subjects and twelve patients diagnosed with hyperthyroidism were recruited. Serum free triiodothyronine (FT3), free thyroxine (FT4) and thyroid stimulating hormone (TSH) levels had been detected by chemiluminescence method. Meanwhile, the catecholamine levels (including adrenaline, noradrenaline, and dopamine) in plasma, ATP level and P2X receptors (including P2X3 receptor and P2X7 receptor) in peripheral blood had been detected by high performance liquid chromatography, bioluminescence method, and reverse transcription polymerase chain reaction, respectively. Levels of epinephrine and norepinephrine were significantly higher in the hyperthyroidism group compared with the control group. The concentration of ATP in the hyperthyroidism group was significantly higher than its in the control group. The expression of P2X3 mRNA and P2X7 mRNA in hyperthyroidism group were significantly increased compared with those in control group. In a conclusion, there is a relationship between the elevated expression of P2X3 receptor and P2X7 receptor in peripheral blood leukocytes and high serum epinephrine and norepinephrine levels in hyperthyroidism patients. © 2016 by the Association of Clinical Scientists, Inc.

Ethoxylated bisphenol A dimethacrylate (bisEMA) is a basis monomer in several dental resin composites. It was the aim of the present study to develop a method allowing detection of bisEMA and its different degrees of ethoxylation eluted from polymerized resin composites. High-temperature gas chromatography/mass spectrometry (HT-GC/MS) by direct on-column injection was used to identify ethoxylated bisEMA in ethanol/water (3:1) eluates from polymerized specimen of four bulk-fill resin composites - Venus(®) bulk fill, Surefil(®) SDR™ flow, Filtek™ Bulk Fill and Sonic Fill™. Additionally, the unpolymerised pastes were analysed. The developed method allowed identification of a homologous series of bisEMA up to twelve ethoxy groups in the unpolymerised materials. The molecular masses of the homologous bisEMA varied between 452 g/mol and 892 g/mol and were detected for retention times from 9.43 min to 13.36 min. Analysis of eluates from polymerised materials identified bisEMA monomers with less than 6 ethoxy groups. Chromatograms showed larger peak areas for the lower volatile bisEMA with 4-6 ethoxy groups compared with higher volatile bisEMA with 2 or 3 ethoxy groups, thus indicating that the amounts of these homologues in the pastes were higher. Ethoxylated bisEMA with up to twelve ethoxy groups can be identified by HT-GC/MS. In all eluates bisEMA was found. The higher the number of ethoxy groups the lower are the peak areas from bisEMA in the gas chromatogram. These findings may be significant for toxicological analysis of resin-composites incorporating bis-EMA. Copyright © 2015 Academy of Dental Materials. Published by Elsevier Ltd. All rights reserved.

How Justice Can Affect Jury Training Abstract Words Promotes Generalization to Concrete Words in Patients with Aphasia

Sandberg, Chaleece; Kiran, Swathi

2014-01-01

Developing language treatments that not only improve trained items but also promote generalization to untrained items is a major focus in aphasia research. This study is a replication and extension of previous work that found that training abstract words in a particular context-category promotes generalization to concrete words but not vice versa (Kiran, Sandberg, & Abbott, 2009). Twelve persons with aphasia (5 female) with varying types and degrees of severity participated in a generative naming treatment based on the complexity account of treatment efficacy (CATE; Thompson, Shapiro, Kiran, & Sobecks, 2003). All participants were trained to generate abstract words in a particular context-category by analyzing the semantic features of the target words. Two other context-categories were used as controls. Ten of the twelve participants improved on the trained abstract words in the trained context-category. Eight of the ten participants who responded to treatment also generalized to concrete words in the same context-category. These results suggest that this treatment is both efficacious and efficient. We discuss possible mechanisms of training and generalization effects. PMID:24805853

A randomized, double-blind, split-face study comparing the efficacy and tolerability of three retinol-based products vs. three tretinoin-based products in subjects with moderate to severe facial photodamage.

PubMed

Babcock, Michael; Mehta, Rahul C; Makino, Elizabeth T

2015-01-01

Retinol, has been shown to improve the appearance of photodamaged skin when applied topically, and is generally considered to be approximately ten times less potent than tretinoin. To assess this theory, three cosmetic formulations containing 0.25%, 0.5%, and 1.0% retinol were developed to correspond to the three commonly prescribed concentrations of tretinoin (0.025%, 0.05%, and 0.1%). A randomized, double-blind, split-face comparison study was conducted to compare the three concentrations retinol (Ret) including 0.25%, 0.5%, and 1.0%, against the respective three strengths of tretinoin (Tret) 0.025%, 0.05%, and 0.1% in subjects with moderate to severe facial photodamage. Subjects were randomized into three groups: Group 1 (Ret 0.25% vs. Tret 0.025%); Group 2 (Ret 0.5% vs. Tret 0.05%); and Group 3 (Ret 1.0% vs. Tret 0.1%). Within each group, subjects were randomized to apply Ret on one half of the face (left or right) and Tret on the other facial side, for a duration of twelve weeks. Clinical evaluations for efficacy and tolerability, as well as standardized digital photographs were conducted at baseline and at weeks 4, 8, and 12. Sixty-five subjects completed the twelve-week study (Group 1: n=24, Group 2: n=20, and Group 3: n=21). At week 12 in all treatment groups, both Ret and Tret produced statistically significant improvements from baseline in all efficacy parameters, including overall photodamage, fine lines/wrinkles, coarse lines/wrinkles, skin tone brightness, mottled pigmentation, and tactile roughness (all P<0.001). There were no significant differences in efficacy between Ret and Tret in these efficacy parameters. Results from this comparison study suggest that this sustained-release retinol complex containing multiple agents for optimal irritation control provides comparable improvements to tretinoin in the appearance of photodamage.

Phylogenetic incongruence in the Drosophila melanogaster species group

PubMed Central

Wong, Alex; Jensen, Jeffrey D.; Pool, John E.; Aquadro, Charles F.

2007-01-01

Drosophila melanogaster and its close relatives are used extensively in comparative biology. Despite the importance of phylogenetic information for such studies, relationships between some melanogaster species group members are unclear due to conflicting phylogenetic signals at different loci. In this study, we use twelve nuclear loci (eleven coding and one non-coding) to assess the degree of phylogenetic incongruence in this model system. We focus on two nodes: (1) The node joining the D. erecta-D. orena, D. melanogaster-D. simulans, and D. yakuba-D. teissieri lineages, and (2) The node joining the lineages leading to the melanogaster, takahashii, and eugracilis subgroups. We find limited evidence for incongruence at the first node; our data, as well as those of several previous studies, strongly support monophyly of a clade consisting of D. erecta-D. orena and D. yakuba-D. teissieri. By contrast, using likelihood based tests of congruence, we find robust evidence for topological incongruence at the second node. Different loci support different relationships among the melanogaster, takahashii and eugracilis subgroups, and the observed incongruence is not easily attributable to homoplasy, non-equilibrium base composition, or positive selection on a subset of loci. We argue that lineage sorting in the common ancestor of these three subgroups is the most plausible explanation for our observations. Such lineage sorting may lead to biased estimation of tree topology and evolutionary rates, and may confound inferences of positive selection. PMID:17071113

2018-04-12

The present follow-up study examines the associations between cognition and parent-rated internalizing problems among adolescents with early-onset schizophrenia (EOS) at baseline (T1) and self-rated internalizing problems 13 years later (T2). Twelve individuals (8 male/4 female) with EOS and 30 healthy controls (16 male/14 female) were included in the study. All were between 12 and 18 years of age at T1. Internalizing problems were measured with the Achenbach System of Empirically Based Assessment Internalizing Scale. Cognition was examined with a neuropsychological test battery measuring auditory attention/working memory, visuomotor processing, cognitive flexibility and verbal memory. Compared to healthy controls, the EOS group had significant cognitive deficits and more internalizing problems both at T1 and T2. There was no correlation between parent-rated internalizing problems at T1 and self-rated internalizing problems at T2 in the EOS group. However, deficits in auditory attention/working memory at T1 were significantly associated with internalizing problems at T2. A focus on improving the treatment of cognitive impairments may be important in preventing the development of internalizing problems in young patients with schizophrenia. The small sample size of the study is a limitation and further research is recommended. Copyright © 2018 Elsevier B.V. All rights reserved.

A prospective randomized control trial. To determine the degree to which a new behavior-based lift training program (LiftTrainer; Ascension Technology, Burlington, VT) could reduce the incidence of low back disorder in distribution center jobs that require repetitive lifting. Most studies show programs aimed at training lifting techniques to be ineffective in preventing low back disorders, which may be due to their conceptual rather than behavioral learning approach. A total of 2144 employees in 19 distribution centers were randomized into either the LiftTrainer program or a video control group. In the LiftTrainer program, participants were individually trained in up to 5, 30-minute sessions while instrumented with motion capture sensors to quantify the L5/S1 moments. Twelve months following the initial training, injury data were obtained from company records. Survival analyses (Kaplan-Meier) indicated that there was no difference in injury rates between the 2 training groups. Likewise, there was no difference in the turnover rates. However, those with a low (<30 Nm) average twisting moment at the end of the first session experienced a significantly (P < 0.005) lower rate of low back disorder than controls. While overall the LiftTrainer program was not effective, those with twisting moments below 30 Nm reported fewer injuries, suggesting a shift in focus for "safe" lifting programs.

It is well known that musicians are a group prone to suffer from playing-related musculoskeletal disorders. Professional orchestra musicians play for several hours a week and have to fight against pain caused by their profession. The aim of this study was to explore and describe self-reported complaints among professional orchestra musicians and to compare its intensity and the prevalence between string and wind instruments. Hundred and twelve professional orchestra musicians from the three main professional orchestras from the North of Portugal were individually interviewed about the prevalence and the intensity (measured by verbal numerical scale for pain) of their playing-related musculoskeletal disorders. About two third (62.5%) of the interviewed musicians presented playing-related musculoskeletal disorders during the time of the interview. Despite there are no significant statistic values between groups, results suggested that playing-related musculoskeletal disorders are more common in string players and more intense in wind players. Referring to the prevalence of playing-related musculoskeletal disorders, our data is in line with other studies from different countries. More than half of professional orchestra musicians in the North of Portugal are playing with a mild to moderate pain. Future studies focusing on working-related problems among professional orchestra musicians in Portugal would be useful to better describe the problem of occupational diseases among performing artist.

Whey protein has been widely applied to athletes and the fitness field for muscle growth and performance improvement. Limited studies focused on the beneficial effects of whey on aerobic exercise according to biochemical assessments. In the current study, 12 elite male track runners were randomly assigned to whey and maltodextrin groups for 5 weeks' supplementation. The aim of this study was to investigate the effect of whey protein on physiological adaptions and exercise performance. During this period, three time points (pre-, post-, and end-test) were used to evaluate related biochemical parameters, body composition, and performance. The post-test was set 1 day after a marathon for injury status evaluation and the end-test was also assessed after 1-week recovery from endurance test. The results showed that the whey group exhibited significantly lower aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, and creatine kinase indicators after the marathon (post-test), as well as at the end-test (p<0.016). The endurance performance in twelve-minute walk/run was also significantly elevated (p<0.012) possibly due to an increase in the muscle mass and amelioration of exercise injuries. In the current study, we demonstrated that whey protein can also be used for aerobic exercise for better physiological adaptation, in addition to resistance training. Whey protein could be also a potential nutrient supplement with a variety of benefits for amateur runners. PMID:28824296

The interaction of health care providers and hospital staff with patients and families at the end of life affects the parental grief experience. Both verbal and nonverbal communication are key components of this interaction. The study objective was to explore the communication between hospital staff members and patients and families at the time of patients' health decline near the end of life. Twelve bereaved parents participated in a focus group. Semantic content analysis was used to analyze the transcript. Parents' responses to the prompt about typical ways the medical team communicated yielded 109 codes, which were grouped into 12 themes. The most common themes were "patient inclusion" and "explanation of medical plan," both used in 17% of responses. Responses to the prompt about positive and negative aspects of communication generated 208 codes, yielding 15 different themes. The most common theme about positive communication was the "strong relationship between family and staff." The theme "variations in care with a negative impact" was used most frequently in describing negative communication. This study helps to identify techniques that should be used by clinicians as they work with children with cancer and their families, particularly including patients in treatment decisions, ongoing relationship building, communicating with caring and empathy, using an interdisciplinary team for additional support, and pairing bad news with a plan of action.

Approaches to priority-setting for scarce resources have shifted to public deliberation as trade-offs become more difficult. We report results of a qualitative analysis of public deliberation in Switzerland, a country with high health-care costs, an individual health insurance mandate and a strong tradition of direct democracy with frequent votes related to health care. We adapted the Choosing Healthplans All Together (CHAT) tool, an exercise developed to transform complex health-care allocation decisions into easily understandable choices, for use in Switzerland. We conducted focus groups in twelve Swiss cities, recruiting from a range of socio-economic backgrounds in the three language regions. Participants developed strategic arguments based on the importance of basic coverage for all, and of cost-benefit evaluation. They also expressed arguments relying on a principle of solidarity, in particular the importance of protection for vulnerable groups, and on the importance of medical care. They struggled with the place of personal responsibility in coverage decisions. In commenting on the exercise, participants found the degree of consensus despite differing opinions surprising and valuable. The Swiss population is particularly attentive to the costs of health care and means of reducing these costs. Swiss citizens are capable of making trade-offs and setting priorities for complex health issues. © 2018 The Authors Health Expectations published by John Wiley & Sons Ltd.

Twelve-step mutual-help groups (TMGs) are among the most available forms of support for homeless individuals with alcohol problems. Qualitative research, however, has suggested that this population often has negative perceptions of these groups, which has been shown to be associated with low TMG attendance. It is important to understand this population's perceptions of TMGs and their association with alcohol outcomes to provide more appropriate and better tailored programming for this multiply affected population. The aims of this cross-sectional study were to (a) qualitatively examine perception of TMGs in this population and (b) quantitatively evaluate its association with motivation, treatment attendance and alcohol outcomes. Participants (N=62) were chronically homeless individuals with alcohol problems who received single-site Housing First within a larger evaluation study. Perceptions of TMGs were captured using an open-ended item. Quantitative outcome variables were created from assessments of motivation, treatment attendance and alcohol outcomes. Findings indicated that perceptions of TMGs were primarily negative followed by positive and neutral perceptions, respectively. There were significant, positive associations between perceptions of TMGs and motivation and treatment attendance, whereas no association was found for alcohol outcomes. Although some individuals view TMGs positively, alternative forms of help are needed to engage the majority of chronically homeless individuals with alcohol problems. Copyright © 2014 Elsevier B.V.

2011-08-01

The idea that diet can affect mood and behavior in women with polycystic ovary syndrome (PCOS) by altering blood glucose levels has become popular in recent years. This paper describes an online survey (N=462) of 24 women with PCOS, 299 healthy control women, 47 women who possibly had undiagnosed PCOS, and 92 men. The groups were compared for symptoms of mood and behavioral symptoms typical of reactive (postprandial) hypoglycemia. The outcome measures were two questionnaires that measure states associated with hypoglycemia: the Hypoglycemia Symptom Checklist-7 (HSC-7), which measures behavioral symptoms and the Mood Adjective Checklist (MACL), which measures emotional states. Controlling for age and body mass index (BMI) using between-groups analysis of covariance (ANCOVA), the women with PCOS scored significantly higher than the other three groups (p<0.001) on the outcome measures. These differences remained statistically significant in a subset of twelve women with PCOS compared to twelve healthy control women closely matched for age, BMI, and eating behavior. The findings are suggestive of hypoglycemia-related mood and behavioral problems in PCOS. Future research should test whether blood glucose levels correlate with these symptoms in PCOS, and whether a low glycemic index ('low-GI') diet improves the symptoms. Copyright © 2011 Elsevier Ltd.

We report new results from high precision analysis of an important BSM gauge theory with twelve massless fermion flavors in the fundamental representation of the SU(3) color gauge group. The range of the renormalized gauge coupling is extended from our earlier work [1] to probe the existence of an infrared fixed point (IRFP) in the β-function reported at two different locations, originally in [2] and at a new location in [3]. We find no evidence for the IRFP of the β-function in the extended range of the renormalized gauge coupling, in disagreement with [2,3]. New arguments to guard the existence of the IRFP remain unconvincing [4], including recent claims of an IRFP with ten massless fermion flavors [5,6] which we also rule out. Predictions of the recently completed 5-loop QCD β-function for general flavor number are discussed in this context.

2003-01-01

To identify success factors for implementing computerized physician order entry (CPOE), our research team took both a top-down and bottom-up approach and reconciled the results to develop twelve overarching principles to guide implementation. A consensus panel of experts produced ten Considerations with nearly 150 sub-considerations, and a three year project using qualitative methods at multiple successful sites for a grounded theory approach yielded ten general themes with 24 sub-themes. After reconciliation using a meta-matrix approach, twelve Principles, which cluster into groups forming the mnemonic CPOE emerged. Computer technology principles include: temporal concerns; technology and meeting information needs; multidimensional integration; and costs. Personal principles are: value to users and tradeoffs; essential people; and training and support. Organizational principles include: foundational underpinnings; collaborative project management; terms, concepts and connotations; and improvement through evaluation and learning. Finally, Environmental issues include the motivation and context for implementing such systems. PMID:14728129

Evaluation of the humoral immune response of children with low level lead exposure

DOE Office of Scientific and Technical Information (OSTI.GOV)

Reigart, J.R.; Graber, C.D.

1976-07-01

Twelve lead-exposed children, with evidence of metabolic impairment, and seven non-lead exposed children were examined for evidence of impairment of their immunological response. There were no differences between the control group and the lead exposed group with reference to complement levels, immunoglobulins, or anamnestic response to the tetanus toxoid antigen. It remains to be demonstrated whether or not there is deficient response to primary immunization, whether other antigens are more affected by lead, or whether impairment of humoral immune response requires a more serious degree of lead intoxication.

Nine children with cerebral palsy and nine adults with stroke were trained using 5 different upper extremity simulations using the NJIT-RAVR system for approximately nine to twelve hours over a three week period. Both groups made improvements in clinical measurements of upper extremity function and reaching kinematics. Patterns and magnitudes of improvement differ between the two groups. Responses to training required adjustment of the robotic system to accommodate the rehabilitation needs of children with cerebral palsy. PMID:22275632

Focus Groups Reveal Differences in Career Experiences Between Male and Female Geoscientists

Oconnell, S.; Frey, C. D.; Holmes, M.

2003-12-01

We conducted twelve telephone focus groups of geoscientists to discover what motivates geoscientists to enter our field and stay in our field. There were separate male and female groups from six different professional categories: administrators, full and associate professors, non-tenure track personnel, assistant professors, post-docs and PhD candidates, Bachelor's and Master's candidates. A total of 96 geoscientists participated. Specifically, respondents were asked what initially brought them into the geosciences. Three dominant themes emerged: the subject matter itself, undergraduate experiences, and relationships. A total of 51 responses to this question related to the subject matter itself. Approximately 61 percent (31) of those responses were given by male focus group participants. Across all focus groups, participants brought up issues such as a general appreciation of the outdoors, weather, rocks, and dinosaurs. Following closely behind the general subject matter is undergraduate events. Fifty-one responses mentioned something about undergraduate experiences such as an introductory class, a laboratory experience, or field experiences. While both female and male participants discussed the role of interpersonal relationships in their decision to become a geoscientist, females were slightly more likely to bring up relevant relationships (26 times for females compared to 21 for males). These relationships varied in both groups from a parent or grandparents influence to camping trips with professors. When respondents were asked whether they had ever considered leaving the geosciences and under what circumstances, there was a striking difference between males and females: males were far less likely to have ever considered leaving. Younger males were more likely to consider leaving than older geoscientists. They feel challenged by the financial constraints of graduate school and the time constraints of academic vs. family life. Many females considered leaving at some point in their careers, from graduate school through the tenure process, and even post-tenure. The challenges they cited included difficult advisors, vague or inadequate advising/mentoring, the lack of support for family by their institutions and by their colleagues, and, like younger males, the balance of work and family life. Our results suggest that some strategies that can increase the numbers of women on our faculty include improving the climate for all under-represented groups and institutional support for families. Climate is a broad area that includes paying attention to: 1) our language, such as what personal comments we make to students and colleagues, 2) assuring that female students are encouraged to speak in class and are permitted to finish sentences without interruption, 3) allowing students to see themselves reflected in the curriculum by acknowledging a broad range of contributions to the field and by seeing more than senior men as professors, 5) adequate, clear-cut mentoring, and 6) open up new faculty searches to capture "less obvious" candidates, such as those that are less self-promoting. Support for families must come from institutions and includes: 1) child care, 2) adult care, 3) flexible schedules including part-time appointments and shared appointments, and 4) dual-career contracts.

Surface design methodology - challenge the steel

The way a product or material is experienced by its user could be different depending on the scenario. It is also well known that different materials and surfaces are used for different purposes. When optimizing materials and surface roughness for a certain something with the intention to improve a product, it is important to obtain not only the physical requirements, but also the user experience and expectations. Laws and requirements of the materials and the surface function, but also the conservative way of thinking about materials and colours characterize the design of medical equipment. The purpose of this paper is to link the technical- and customer requirements of current materials and surface textures in medical environments. By focusing on parts of the theory of Kansei Engineering, improvements of the companys' products are possible. The idea is to find correlations between desired experience or "feeling" for a product, -customer requirements, functional requirements, and product geometrical properties -design parameters, to be implemented on new improved products. To be able to find new materials with the same (or better) technical requirements but a higher level of user stimulation, the current material (stainless steel) and its surface (brushed textures) was used as a reference. The usage of focus groups of experts at the manufacturer lead to a selection of twelve possible new materials for investigation in the project. In collaboration with the topical company for this project, three new materials that fulfil the requirements -easy to clean and anti-bacterial came to be in focus for further investigation in regard to a new design of a washer-disinfector for medical equipment using the Kansei based Clean ability approach CAA.

Traumatic brain injury often negatively impacts episodic memory; however, studies of the neural substrates of this impairment have been limited. In this study, both encoding and recognition of visually presented stimuli were examined with functional magnetic resonance imaging. Twelve adults with chronic complicated mild, moderate, and severe injuries were compared with a matched group of 12 controls. Behavioral task performance did not differentiate the groups. During neuroimaging, however, the group of individuals with traumatic brain injury exhibited increased activation, as well as increased bilaterality and dispersion as compared to controls. Findings are discussed in terms of increased resource recruitment.

The Mahomet aquifer: A transboundary resource in east-central Illinois

Larson, D.R.; Mehnert, E.; Herzog, B.L.

2003-01-01

Emerging intrastate transboundary issues focus on use of the Mahomet aquifer, which underlies about fifteen counties and many other political entities in east-central Illinois. This sand and gravel aquifer in the lower part of the buried Mahomet Bedrock Valley ranges between four and fourteen miles wide and from about 50 to 200 feet thick. Much of the region's rural population, several large communities, and many small towns obtain water from the Mahomet aquifer, as do industrial, agricultural, and commercial users. Increased development of the Mahomet aquifer to meet growing demands for water has caused conflicts over real or perceived adverse effects. One result has been the creation of fifteen resource protection zones and twelve water authorities. For groundwater supplies, resource protection zones help municipalities protect water-supply wells from potential adverse impacts. Many resource protection zones overlap one another, however, so this situation could lead to disputes over use of the resource. The reason that several of the twelve water authorities were organized was to meet a challenge perceived from a demand to be placed on the aquifer, in other words, a potential for conflict of use. Complicating the situation is that some of the water authorities overlap the resource protection zones. This could lead to disputes not only about water use, but also over which jurisdiction has the authority to settle a dispute. The Mahomet Aquifer Consortium was recently organized by concerned people representing diverse groundwater interests at the local level, including the private sector, professional organizations, and various governmental units. The consortium brings together representatives of some groups that typically did not communicate with each other in the past. The consortium may provide a forum through which emerging transboundary issues pertaining to use of the Mahomet aquifer can be addressed. Because the consortium is a voluntary organization that relies on Consensus building, the success it may achieve in resolving future conflicts over groundwater use from the Mahomet aquifer remains to be seen.

Background Smoking cessation plays a crucial role in reducing preventable morbidity and mortality and is a recognized public-health-policy issue in many countries. Two of the most important factors that affect the efficacy of quitting smoking are motivation and the ability to cope with situations causing relapse. Aim The objective of the study reported here was to investigate former and current smokers’ motivations for smoking cessation, reasons for relapse, and modes of quitting. Methods We arranged four focus groups with 24 participants (twelve current and twelve former smokers) and eleven semi-structured interviews (five current and six former smokers) with a view to understanding and categorizing their opinions on motivations and the course and process of smoking cessation. The data were next analyzed using descriptive qualitative methods. Results Three main themes were identified: (1) motivations to quit smoking, (2) reasons why smokers sometimes relapse, and (3) modes of quitting smoking. Within the first theme, the following six subthemes surfaced: (1) a smoking ban at home and at work due to other people’s wishes and rules, (2) the high cost of cigarettes, (3) the unpleasant smell, (4) health concern, (5) pregnancy and breastfeeding, and (6) a variety of other factors. The second theme encompassed the following subthemes: (1) stress and the need to lessen it by smoking a cigarette, (2) the need to experience the pleasure connected with smoking, and (3) the smoking environment both at home and at work. Participants presented different smoking-cessation modes, but mainly they were unplanned attempts. Conclusion Two very important motivations for smoking cessation were a smoking ban at home and at work due to other people’s wishes and rules, and the high cost of cigarettes. The most common smoking-cessation mode was a spontaneous decision to quit, caused by a particular trigger factor. Relapse causes encompassed, most notably: stress, lack of the pleasure previously obtained from smoking, and the smoking environment. PMID:25336926

Vocal repertoire of free-ranging black howler monkeys' (Alouatta pigra): Call types, contexts, and sex-related contributions.

Alouatta species utter the most powerful primate vocalizations in the Neotropics and are well-known for their loud and long-lasting male howling bouts. However, the diversity of acoustic structures used in these howling bouts, as well as in non-howling contexts, and the relative contribution of the different group members to the entire vocal repertoire, needed to be explored further. This report provides the first detailed description of the vocal repertoire of black howler monkeys (Alouatta pigra), focusing on acoustic structures and contexts of emission of both loud and soft calls as well as on the contribution rate of males and females to the different call types. Three free-ranging social groups of black howler monkeys living in Palenque National Park, Mexico were monitored. We identified twelve acoustically discriminable call types, eight described previously and four described here for the first time. A few call types were systematically emitted either isolated or during howling bouts, but most of them could be heard in both calling contexts. Three call types were emitted only by females and two only by males. Adult males' call rates (for the seven shared call types) were higher than those of females but only when considering calls emitted within howling bouts. Our contextual analysis enabled us to divide call types into potential functional categories, according to their degree of contribution, to intra-group versus inter-group interactions and to neutral-positive versus negative situations. We then discussed how socio-ecological factors, notably sex differences in social behaviors, may explain the variability found in the vocal repertoire of this species and compared our findings with the literature on other primate species. © 2017 Wiley Periodicals, Inc.

Introducing the AAS Working Group on Astroinformatics and Astrostatistics

2014-01-01

In response to two White Papers submitted to the Astro2010 Decadal Survey (1,2), a new AAS Working Group on Astroinformatics and Astrostatistics (WGAA) has been approved by the AAS Council at the 220th Meeting, June 2012, in Anchorage. The motivation for this WG is the growing importance of the interface between astronomy and various branches of applied mathematics, computer science and the emerging field of data science. With the new data-intensive projects envisioned for the coming decade, the need for advice derived from the focused attention of a group of AAS members who work in these areas is bound to increase. The Working Group is charged with spreading awareness of rapidly advancing computational techniques, sophsticated statistical methods, and highly capble software to further the goals of astronomical and astrophysical research. The three main strategic goals adopted by the WGAA Steering Committee for the next few years are to: (i) develop, organize and maintain methodological resources (such as software tools, papers, books, and lectures); (ii) enhance human resources (such as foster the creation of career paths, establish a Speakers' Bureau, establish and maintain an archived discussion forum, enable periodic news distribution); and (iii) organize topical meetings. The WGAA Steering Committee at this time includes twelve members: Kirk Borne, George Djorgovski, Eric Feigelson, Eric Ford, Alyssa Goodman, Joe Hilbe, Zeljko Ivezic (chair), Ashish Mahabal, Aneta Siemiginowska, Alex Szalay, Rick White, and Padma Yanamandra-Fisher. I will summarize our accomplishments since July 2012.

Age differences in medial prefrontal activity for subsequent memory of truth value

PubMed Central

Cassidy, Brittany S.; Hedden, Trey; Yoon, Carolyn; Gutchess, Angela H.

2014-01-01

Much research has demonstrated that aging is marked by decreased source memory relative to young adults, yet a smaller body of work has demonstrated that increasing the socioemotional content of source information may be one way to reduce age-related performance differences. Although dorsomedial prefrontal cortex (dmPFC) activity may support source memory among young and older adults, the extent to which one activates dorsal vs. ventral mPFC may reflect one's personal connection with incoming information. Because truth value may be one salient marker that impacts one's connection with information and allocation of attention toward incoming material, we investigated whether the perceived truth value of information differently impacts differences in mPFC activity associated with encoding source information, particularly with age. Twelve young (18–23 years) and 12 older adults (63–80 years) encoded true and false statements. Behavioral results showed similar memory performance between the age groups. With respect to neural activity associated with subsequent memory, young adults, relative to older adults, exhibited greater activity in dmPFC while older adults displayed enhanced ventromedial prefrontal cortex (vmPFC) and insula engagement relative to young. These results may potentially indicate that young adults focus on a general knowledge acquisition goal, while older adults focus on emotionally relevant aspects of the material. The findings demonstrate that age-related differences in recruitment of mPFC associated with encoding source information may in some circumstances underlie age-equivalent behavioral performance.

Sensitivity of the activated partial thromboplastin time, the dilute Russell's viper venom time, and the kaolin clotting time for the detection of the lupus anticoagulant: a direct comparison using plasma dilutions.

PubMed

Martin, B A; Branch, D W; Rodgers, G M

1996-01-01

Increasing dilutions of lupus anticoagulant (LA) plasmas from twelve patients were used to directly compare the sensitivity of four tests for LA. The tests evaluated were the modified Bell and Alton activated partial thromboplastin time (APTT), an APTT using a commercially prepared partial thromboplastin (Platelin LS APTT), a modified dilute Russell's viper venom time (DRVVT), and a modified kaolin clotting time (KCT). LAs were detected in all twelve plasmas by each of three tests and eleven of twelve plasmas in a fourth test when undiluted patient plasma was used. Repeating the tests after diluting the LA plasmas with normal platelet-free plasma (PFP) showed that the KCT was the most sensitive test for LA, detecting eleven of twelve LAs at a dilution of 10% patient plasma and ten of twelve LAs at a dilution of 5% patient plasma. The modified Bell and Alton APTT and the modified DRVVT had similar sensitivities at a patient plasma concentration of 10%, detecting seven of twelve and eight of twelve LAs, respectively. The Platelin LS APTT detected only four of twelve LAs at a patient plasma concentration of 10%. Our results indicate that the modified KCT is a sensitive method for the detection of LAs. The modified Bell and Alton APTT and the DRVVT were less sensitive.

12-Month Results From the First-in-Human Randomized Study of the Ranger Paclitaxel-Coated Balloon for Femoropopliteal Treatment.

The authors sought to evaluate the performance of the Ranger paclitaxel-coated balloon versus uncoated balloon angioplasty for femoropopliteal lesions at 12 months. Drug-coated balloons (DCBs) are a promising endovascular treatment option for peripheral artery disease of the femoropopliteal segment, and each unique device requires dedicated clinical study. The prospective, randomized RANGER SFA (Comparison of the Ranger™ Paclitaxel-Coated PTA Balloon Catheter and Uncoated PTA Balloons in Femoropopliteal Arteries) study (NCT02013193) enrolled 105 patients with symptomatic lower limb ischemia (Rutherford category 2 to 4) and stenotic lesions in the nonstented femoropopliteal segment at 10 European centers. Seventy-one patients (mean age 68 ± 8 years, n = 53 men) were enrolled in the Ranger DCB arm, and 34 patients (mean age 67 ± 9 years, n = 23 men) were assigned to the control group. Twelve-month analysis included patency, safety, and clinical outcomes and quality-of-life assessments. The DCB group had a greater primary patency rate at 12 months (Kaplan-Meier estimate 86.4% vs. 56.5%), with a significantly longer time to patency failure (log-rank p < 0.001). The estimated freedom from target lesion revascularization rate was 91.2% in the DCB group and 69.9% in the control group at 12 months, with a significantly longer time to reintervention (p = 0.010). No target limb amputations or device-related deaths occurred in either group. Twelve-month results show that patency was maintained longer after Ranger DCB treatment than after conventional balloon angioplasty, and this result was associated with a low revascularization rate and good clinical outcomes.

Contingency management (CM) is one of the most common therapies in the domain of drug addiction. This study has been carried out with the purpose of evaluating the efficacy of contingency management intervention. In an experimental design, between December 15, 2014 and November 20, 2015, fifty men (between 18 and 31 with an average age of 24.6) with a history of cocaine use, were selected voluntarily and were randomly assigned into two groups of CM and control group. The CM group were awarded coupons for negative urine tests, over a period of twelve weeks. The urine tests were taken from the participants twice per week, with cutoff concentrations for positive set at 300 ng/ml and self-reporting index of cocaine craving (response rate = 96%) were evaluated in two phase, through pretest and posttest measures. The data were analyzed by parametric covariance test. Additionally, the qualitative data, resulted from demographic measures, were coded and were analyzed with the help of an analysis instrument of qualitative data i.e. ATLAS.ti-5.2. The primary outcome was the number of negative urine tests and the secondary outcome included the cocaine usage craving index over twelve weeks. The mean of (95% of confidence) number of negative cocaine urine tests was 15.4 (13.1-17.8) in the CM group and 19.7 (17.7-21.6) in the control group (P = 0.049). Also, results showed that CM has a significant effect on reducing craving (p<0.01). The findings of this study, while having practical aspects in this domain, can be valuable in planning remedial procedures.
