O método Kumon para remediação cognitiva de portadores de esquizofrenia: um ensaio clínico randomizado, controlado com placebo / The Kumon Method for cognitive remediation of individuals with schizophrenia: a randomized, placebo-controlled trial

Romão, Marisa Martin Crivelaro 17 June 2013 (has links)
Introdução: Déficits cognitivos são parte integrante do quadro clinico da esquizofrenia. Vários estudos procuram métodos de treinamento cognitivo (remediação cognitiva) para melhora destes déficits, pouco responsivos ao tratamento medicamentoso. Ensaios clínicos de treinamento de remediação cognitiva utilizam diversas técnicas, com estimulação de vários domínios cognitivos simultaneamente. Muitos deles utilizam a técnica de errorless learning (aprendizagem sem erros). Pesquisas recentes indicam que alguns domínios cognitivos subjacentes à aprendizagem matemática (atenção, função executiva e memória de trabalho) estão também comprometidos na esquizofrenia. Entretanto não foram encontrados estudos de remediação cognitiva focados no treinamento aritmético em portadores de esquizofrenia. O método de cálculos aritméticos proposto pelo método Kumon utiliza técnica de aprendizagem sem erros e é amplamente utilizado como reforço pedagógico. Dois ensaios randomizados de remediação cognitiva através do método de cálculo aritmético Kumon em idosos sadios e em idosos com Alzheimer mostraram melhora de funções cognitivas com esta intervenção. Este estudo avaliou a eficácia do método de cálculos aritméticos Kumon como remediação cognitiva da memória de trabalho, função executiva e atenção na população com esquizofrenia. Método: 51 sujeitos com o diagnóstico de esquizofrenia (DSM-IV), de ambos os gêneros, idade entre 18 e 55 anos, alfabetizados foram incluídos e randomizados para treinamento de cálculos aritméticos pelo método Kumon (grupo experimental) ou atividades de recreação (grupo controle). Os sujeitos fizeram 48 sessões de intervenção ao longo de 6 meses. Os sujeitos foram avaliados através de uma bateria neuropsicológica, o desfecho clínico através da escala Escala de Síndromes Positiva e Negativa (PANSS) e funcionamento pessoal e social através da PSP no inicio da intervenção, após 6 meses (término da intervenção) e após 6 meses sem a intervenção. Resultados: O grupo experimental apresentou tendência de melhora em atenção sustentada (p=0.075), mas sem manutenção dos ganhos após 6 meses sem intervenção. Ambos os grupos apresentaram melhora em atenção seletiva e função executiva após 6 meses sem manutenção dos ganhos após 1 ano, sem diferenças entre os grupos. Não foram encontradas diferenças no funcionamento social entre os dois grupos e ao longo dos 12 meses de acompanhamento. Através da análise fatorial da PANSS utilizando 5 fatores (proposto por Van der Gaag 2006) não houve mudança significativa nos fatores ,,positivo\", ,,negativo\", ,,desorganização\" e ,,estresse emocional\" ao longo do tempo e entre os grupos. Apenas o grupo placebo demonstrou melhora significativa no fator \"excitação\" após 6 meses em comparação com o grupo experimental, que não persistiu após 6 meses sem intervenção. Conclusão: O treino cognitivo aritmético pelo método Kumon tende a melhorar a atenção sustentada após 6 meses, sem impacto na função executiva e na memória de trabalho. Esta tendência não se manteve após 6 meses sem intervenção / Introduction: Cognitive deficits are an integral part of the clinical picture of schizophrenia. Various studies seek cognitive training (cognitive remediation) methods in order to improve those deficits, which are poorly responsive to pharmacological treatment. Clinical trials of cognitive remediation training use a variety of techniques, with the stimulation of several cognitive domains simultaneously. Many of them employ the \"errorless learning\" technique. Recent research indicates that some cognitive domains underlying mathematical learning (attention, executive function and working memory) are also impaired in schizophrenia. However, no cognitive remediation studies were found focusing on arithmetic training in individuals with schizophrenia. The arithmetic calculation method proposed by Kumon employs the errorless learning technique and is widely used for supplemental education. Two randomized trials of cognitive remediation using the arithmetic calculation method Kumon with healthy elderly subjects as well as elderly subjects who had Alzheimer\'s disease showed cognitive function improvement with this intervention. The present study evaluated the effectiveness of the arithmetic calculation of the Kumon method as cognitive remediation for working memory, executive function and attention in a sample with schizophrenia. Method: 51 subjects with a diagnosis of schizophrenia (DSM-IV), male and female, literate, aged between 18-55 years, were included in the trial and randomized to arithmetic calculation training by the Kumon method (experimental group) or recreational activities (control group). The subjects received 48 intervention sessions over the course of 6 months. The subjects were evaluated through a neuropsychological battery; the clinical outcome was assessed by the Positive and Negative Syndrome Scale (PANSS), and personal and social functioning was evaluated using the Personal and Social Performance (PSP) scale at baseline, at 6 months (discontinuation of interventions) and after 6 months without interventions. Results: The experimental group tended to an improvement in sustained attention (p=0.075), yet this was not maintained after 6 months without interventions. Both groups showed improvements in selective attention and executive function at 6 months, which were not maintained after one year, with no differences between groups. No differences were found in social functioning between the groups and throughout the 12 follow-up months. The factor analysis of the 5-factor PANSS (as proposed by Van der Gaag, 2006) showed no significant change in the factors \"positive\", \"negative\", \"disorganization\" and \"emotional distress\" over time and between groups. Only the placebo group exhibited a significant improvement in the factor \"excitement\" after 6 months compared with the experimental group, which was not maintained after 6 months without interventions. Conclusion: The cognitive arithmetic training by the Kumon method tends to improve sustained attention after 6 months, with no impact on either executive function or working memory. This trend was not sustained after 6 months without interventions

Efeito adicional da fisioterapia ao tratamento medicamentoso na redução da frequência e intensidade da migrânea: ensaio controlado randomizado / Additional effect of physical therapy to medication treatment in reducing the frequency and intensity of migraine: a randomized controlled trial

Gonçalves, Maria Claudia 28 March 2014 (has links)
A migrânea está relacionada às disfunções das estruturas da coluna cervical, impulsos aferentes desse local podem ser facilitadores ou mesmo gatilhos da dor. Tratamentos com manipulação cervical isolada e combinada a medicação já foram testados, porém os resultados são conflitantes. O objetivo desse trabalho foi avaliar o efeito adicional da fisioterapia ao tratamento medicamentoso da migrânea na frequência, intensidade e duração da dor de cabeça. Foram inclusas mulheres com migrânea, na faixa etária de 18 e 55 anos, com mínimo de 06 dias de dor por mês, e que apresentasse dor na região craniocervical através do relato. Cinquenta mulheres foram igualmente randomizadas para um dos dois grupos de tratamento, Grupo Fisioterapia (terapia manual + medicação) e Grupo Controle (medicação). O diagnóstico de migrânea foi realizado por uma única neurologista, segundo a Classificação Internacional de Cefaleias. Foram realizadas 12 sessões de terapia manual, duas vezes por semana, durante 50 minutos, por uma única fisioterapeuta. A avaliação, a reavaliação e follow-up foram cegos. Os desfechos primários de frequência, intensidade e duração da dor de cabeça, foram avaliados por meio do diário de dor; e secundários, Limiar de dor por pressão (Algômetro), incapacidade relacionada à cefaleia (Migraine disability assessment program) e a coluna cervical (Neck disability índex), Patient Health Questionnaire eight-item depression scale (PHQ-8), alodinia com Allodynia Sympton Checklist (ASC- /12) e satisfação com Patients Global Impression of Change Scale (PGIC). A análise foi realizada por intenção de tratamento e foi utilizado o Modelo Linear de efeitos mistos e para atribuir relevância clínica o Effect size (ES) e Mínima mudança importante (MID). Não foram observadas diferenças entre os grupos na avaliação inicial. O GF apresentou redução de 37% na frequência de dias de dor de cabeça comparado ao GC que apresentou 22% (p<0.05 e ES 0,4) e (p<0.05 e ES 0,3) respectivamente. Não foram observadas diferenças clínicas significativas entre os grupos na duração e na intensidade da dor de cabeça. Também foi observado aumento significativo (p<0,05) do limiar de dor por pressão, bem como maior satisfação e percepção de mudança da doença ao paciente (p<0,05) no GF em comparação ao GC. Não foram observadas diferenças significativas nos demais parâmetros avaliados. A redução do limiar de dor dos músculos cervicais com o tratamento fisioterapêutico promoveu um efeito benéfico adicional ao medicamentoso, com maior redução da frequência de dias de dor de cabeça e maior satisfação e percepção de melhora dos pacientes. REBEC nº RBR-6kvx74 / Migraine is related to disorders of the cervical spine structures, afferent impulses that location can be facilitators or even triggers pain. Treatments with cervical manipulation alone and combined medication have been tested, but results are conflicting. The aim of this study was to evaluate the additional effect of physical therapy to drug treatment of migraine in frequency, intensity and duration of headache. Women with migraine were included, aged 18 to 55 years, with a minimum of 06 days of pain per month and report of pain in the craniocervical region. Fifty women were equally randomized to one of the two treatment groups, Physiotherapy Group (manual therapy and medication) and control group (medication). The diagnosis of migraine was performed according to the International Classification of headache by a single neurologist. All subjects received similar medications. 12 sessions of manual therapy, twice per week, during for 50 minutes, were done by same physical therapist. The assessment, revaluation and follow-up were blind. The primary endpoints of frequency, intensity and duration of headache were evaluated through diary pain, and secondary endpoints like pain threshold pressure (algometer), headache related disability (Migraine disability assessment program) and cervical spine (Neck disability index), patient Health Questionnaire eight- item depression scale (PHQ-8), with the severity of Allodynia Sympton Checklist (ASC-12) and patients Global Impression of Change Scale to assess satisfaction and perception of patient changes as its disease condition. The analysis was by intention to treat and we used the linear mixed effects model. To assign the clinical relevance Effect size (ES) and Minimum important change (MID) were used. No differences between groups were observed at baseline. The PG showed a 37% reduction in the frequency of headache days compared to GC showed that 22 % (p<0.05 to ES0.4) and (p<0.05 to ES0.3) respectively. No clinically significant differences were observed between groups regarding the duration and intensity of the headache. Significant increase (p<0.05) pain threshold pressure was also observed, as well as greater satisfaction and changing perception of the disease to the patient (p<0.05) in the PG compared with the CG. No significant differences were observed in the other parameters. The reduction of the pain threshold of cervical muscles with physical therapy promoted a beneficial additional effect to medication, with greater reduction in frequency of headache days and greater satisfaction and perceived improvement of patients.

Resposta de molares e não molares a dois distintos protocolos de manutenção periódica preventiva : análise longitudinal / Response of molar and non-molar teeth to two different periodic preventive maintenance : protocols :longitudinal analysis

Jaskulski, Ana Paula January 2016 (has links)
Objetivos: o objetivo do presente estudo é avaliar a resposta molares e não molares a dois protocolos de atenção periodontal na fase de manutenção periódica preventiva (MPP). Métodos: Sessenta e dois pacientes com periodontite moderada ou avançada (idade média 50.97 ± 9.26 anos, 40 mulheres, 24 fumantes) foram tratados de acordo com um protocolo não-cirúrgico. Finalizada a fase terapêutica, os pacientes iniciaram a fase de MPP e foram randomicamente alocados para receber controle supragengival isolado (SPG) ou combinado ao subgengival (SPG+SBG). Exames periodontais, instruções de higiene bucal e as respectivas intervenções experimentais foram realizados em consultas trimestrais. Resultados: não foram observadas diferenças significativas nas variáveis demográficas, número médio de dentes e distribuição média de dentes não-molares/molares e de sítios livres/proximais entre os dois grupos experimentais. Quando do baseline, os dentes molares apresentaram um maior número de sítios positivos para IPV, ISG, SS e maiores valores médios de PS e PI quando comparados aos não-molares (p<0.001). Ao longo da fase de MPP, foi demonstrado que independente da terapia aplicada, tanto para molares e não molares, a resposta para ambos os grupos dentários não foi diferente. Da mesma forma, a perda dentária entre molares e não molares não diferiu ao longo de 24 meses. Conclusões: Molares apresentam semelhante resposta durante a fase de MPP quando comparados a dentes não molares, independente do protocolo de intervenção clínica aportado. / Aim: The objective of the present study was to evaluate the response of molar teeth and non-molar teeth to two periodontal care protocols in the periodic preventive maintenance phase (PMP). METHODS: Sixty-two patients with moderate or advanced periodontitis (mean age 50.97 ± 9.26 years, 40 women, 24 smokers) were treated according to a non-surgical protocol. After the therapeutic phase, the patients started the PMP and were randomly assigned to receive supragingival (SPG) or combined subgengival (SPG + SBG) control. Periodontal examinations, oral hygiene instructions and the respective experimental interventions were performed in quarterly consultations. Results: There were no significant differences in demographic variables, mean number of teeth and mean distribution of non-molar / molar teeth and free / proximal sites between the two experimental groups. At the baseline, molar teeth had a higher number of positive sites for VPI, GBI, BOP and higher mean values of PPD and CAL when compared to non-molars (p <0.001). Throughout the MPP phase, it was demonstrated that regardless of the applied therapy, for both molars and non-molars, the response for both dental groups was not different. Likewise, tooth loss between molars and non-molars did not differ over 24 months. Conclusions: Molars presented a similar response during the PMP when compared to non-molar teeth, independent of the protocol of clinical intervention provided.

A clinical practice model of music therapy to address psychosocial functioning for persons with dementia: model development and randomized clinical crossover trial

Reschke-Hernández, Alaine Elizabeth 01 May 2019 (has links)
Background: By 2050, it is estimated that 14 million older Americans will live with Alzheimer’s disease (AD), a progressive form of dementia with unknown cause or cure. Persons with AD and related dementias (ADRD) become increasingly dependent on others as they experience cognitive decline, which concomitantly undermines individuals’ functional skills, social initiative, and quality of life. The Alzheimer’s Association advocates for interventions that address cognition, mood, behavior, social engagement, and by extension, quality of life – goals music therapists often address. Although a small but growing body of literature suggests that clinical music therapy may be effective, the evidentiary support for the use and appropriate application of music as a form of treatment with this population is currently limited. Objectives: This thesis consisted of the development of a Clinical Practice Model of music therapy for persons with ADRD. It also examined the effectiveness of a specific, protocol-based music therapy intervention, grounded in this model, relative to a verbal discussion activity. Methods: The Clinical Practice Model is theoretically grounded in the biopsychosocial model of healthcare (Engel, 1980) and Kitwood’s (1997) personhood framework, and I developed it through extensive literature review and expert input. It includes an organizational schema for applying intervention strategies, per six themes: cognition, attention, familiarity, audibility, structure, and autonomy. The initial model predicts that an intervention built upon this schema will influence social-affective responses, quality of life, and in turn, psychosocial symptoms of ADRD. I tested a singing-based music therapy intervention, grounded in this model, through a randomized clinical crossover trial. I compared participants’ responses to music therapy to a non-music verbal discussion activity, and both conditions followed a protocol. Dependent variables included: (1) affective responses (self-reported feelings, observed emotions, and observed mood), (2) social engagement, and (3) observed quality of life. Thirty-two individuals with ADRD (n = 6 men, n = 26 women) ages 65-97 years old (μ̂ = 84.13) participated in this study. I randomly assigned treatment order; each treatment occurred in small-group format, three times per week in the afternoon (25 minutes each session), for two consecutive weeks. A two-week “wash-out” period occurred between conditions. Credentialed music therapists led both study conditions. This study followed recommendations from the National Institutes of Health Behavior Change Consortium (Bellg et al., 2004) to enhance quality assurance in protocol administration and data collection. Results and Significance: I used a linear mixed model approach to analysis. Music therapy exacted a significant, positive effect on self-reported feelings, observed emotions, and constructive engagement, particularly for individuals with moderate dementia. Results also suggested that men’s feelings improved in response to music therapy only, whereas women responded positively to both conditions. Weekly observations failed to indicate a significant change in mood or quality of life across the eight-week study. Based on these findings, I revised the Clinical Practice Model to include wellbeing (an outcome more concordant with psychosocial change in response to music intervention) rather than global quality of life (affected by numerous aspects of the care milieu). In addition to the Clinical Practice Model to the music therapy profession, contributions of this thesis include a rigorous clinical study and practical implications for music therapy practice, including the importance of considering patient characteristics and careful selection and implementation of music in a music therapy intervention.

An Eating Frequency Prescription for a Behavioral Weight Loss Intervention

Bachman, Jessica Lynne 01 August 2011 (has links)
Improved weight loss interventions are needed to help reduce obesity. One dietary factor that has been effective in increasing weight loss is increased dietary structure. One method for increasing dietary structure is prescribing the frequency in which eating bouts (meals and snacks) occur. Eating frequency (EF) has been inversely related to body mass index (BMI) but the impact of EF on weight loss is unclear. This randomized controlled trial examined the effect of EF on hunger, the relative-reinforcing value of food, energy intake (EI), and weight loss during a 6 month behavioral weight loss intervention. Participants (age: 51.0 ± 9.9 yrs, BMI: 35.5 ± 4.8 kg/m2, 57.8% female, 94.1% white) were randomized to one of two EF prescriptions: 1) Three Meal (n=25): three eating bouts/day; or 2) Grazing (n=26): eat at least 100 kcals every 2-3 hrs. Both groups attended 20 sessions and had identical dietary (1200–1500 kcals/day, < 30% kcals from fat) and physical activity (200 minutes/wk) goals. Hunger, relative-reinforcing value of food, diet, and anthropometric data were collected at 0 and 6 months. Using intent-to-treat analyses, Grazing reported a greater EF (eating bouts in which > 25 kcals were eaten/day) than Three Meal at 6 months (5.8 ± 1.1 eating bouts vs. 3.2 ± 0.6 eating bouts, p<0.001). On a 100-mm visual analogue scale Grazing reported significantly less hunger at 6 months as compared to 0 months (47.9 ± 18.5 mm vs. 56.3 ± 15.7 mm, p<0.05), while Three Meal did not report any changes. There were no significant differences in the relative-reinforcing value of food between groups or over time. EI and BMI were significantly (p<0.001) reduced from 0 to 6 months (EI: 0 months = 2198 ± 692 kcals/day vs. 6 months = 1266 ± 353 kcals/day; BMI: 0 months = 35.5 ± 4.8 kg/m2 vs. 6 months = 30.6 ± 4.9 kg/m2). There were no significant differences in EI or BMI between the groups. An EF of approximately six eating bouts/day may decrease hunger more so than an EF of three meals/day while consuming a low-kcal diet during a behavioral weight loss intervention.

A Randomized Controlled Trial of the Effects of Guided Imagery on Blood Pressure in Hypertensive Pregnant Women

Wight Moffatt, C. Faith 26 February 2009 (has links)
Hypertension occurs in nearly 10% of pregnancies, and is associated with infant and maternal morbidity and mortality. Prior studies of non-pregnant adults have demonstrated the effectiveness of a variety of relaxation therapies in reducing blood pressure. A pilot randomized controlled trial was conducted, the purposes of which were 1) to provide preliminary evidence regarding the usefulness of guided imagery (GI) in reducing blood pressure in hypertensive pregnant women, and 2) to answer feasibility questions for a larger trial. Pregnant women with hypertension prior to 37 weeks gestation (n = 69) were randomized to either 15-minute periods of guided imagery (n = 34), or of quiet rest (QR) (n = 35), twice daily for four weeks or until delivery, whichever came first. Daytime ambulatory mean arterial pressure (MAP), systolic and diastolic blood pressures, anxiety, rest and GI use were measured weekly, to a maximum of four weeks. Sixty women completed at least one week in the study; 46.4% completed four weeks. Compliance was excellent. Intention to treat analysis was used. In the unadjusted analysis, women allocated to GI had significantly lower average daytime ambulatory mean MAP elevations from baseline to their last week of study participation than women allocated to quiet rest (GI: M = 1.58 mmHg, SD = 7.63; QR: M = 5.93 mmHg, SD = 6.55; t = 2.36, p = .02). However, the effect was no longer statistically significant (p = 0.14) when adjusted for baseline mean arterial pressure and gestation. There was no statistically significant difference in the numbers of women who were prescribed antihypertensive medication after randomization (GI: n = 16, QR: n = 13, X2 = 0.74, p = .46). There was also no evidence of an effect of guided imagery on anxiety. Nearly 90% (n = 26) of the guided imagery group indicated they would use it again, either in a subsequent pregnancy or during stressful life events. Given the ease of use, low cost, acceptability to women, and lack of risk of guided imagery, an adequately-powered randomized controlled trial is warranted.

Physical exercise for older people : focusing on people living in residential care facilities and people with dementia

Littbrand, Håkan January 2011 (has links)
The main purposes of this thesis were to evaluate a high-intensity functional weight-bearing exercise pro­gramme, regarding its applicability (attendance, achieved intensity, adverse events) as well as its effect on physical functions and activities of daily living (ADL) among older people living in residential care facilities, with a special focus on people with dementia. Furthermore, a main purpose was to systematically review the applicability and effects of physical exercise on physical functions, cognitive functions, and ADL among people with dementia. A high-intensity functional weight-bearing exercise programme that includes lower-limb strength and balance exercises in standing and walking, was evaluated in a randomised controlled trial among 191 older people, dependent in ADL, living in residential care facilities, and with a Mini-Mental State Examination (MMSE) score of ten or more. One hundred (52.4%) of the participants had dementia. Participants were randomised to an exercise programme or a control activity, consisting of 29 supervised sessions over 3 months, as well as to an intake of a protein-enriched energy supplement or a placebo drink immediately after each session. The effect on physical functions was evaluated using the Berg Balance Scale, usual and maximum gait speed, and one-repetition maximum in a leg press machine measuring lower-limb strength. The effect on ADL was evaluated using the Barthel Index. These outcome measures were followed up at 3 and 6 months by blinded assessors and analysed using the intention-to-treat principle. The evaluation of the applicability of the high-intensity functional weight-bearing exercise programme showed that there was a high rate of attendance, a relatively high achieved intensity in the exercises, and all except two adverse events were assessed as minor or temporary and none led to manifest injury or disease. No statistically significant differences were observed in applicability when comparing participants with dementia and participants without dementia. In addition, the applicability of the programme was not associated with the participants’ cognitive function. Significant long-term effects of the exercise programme were seen regarding functional balance, gait ability and lower-limb strength in comparison with the control activity. The intake of the protein-enriched energy supplement did not increase the effect of the training. Age, sex, depression, dementia disorder, nutritional status, and level of functional balance capacity did not influence the effect on functional balance of the high-intensity functional weight-bearing exercise programme. There were no significant differences between the groups regarding overall ADL performance. Analyses for each item revealed that a significantly smaller proportion of participants in the exercise group had deteriorated regarding indoor mobility at 3 and 6 months. For people with dementia, there was a significant difference in overall ADL performance in favour of the exercise group at 3 months, but not at 6 months. In a systematic review, randomised controlled trials, evaluating the effects of physical exercise among people with dementia, were identified according to pre-defined inclusion criteria. Two reviewers independently extracted predetermined data and assessed methodological quality. Ten studies were included in the review and the majority of the participants were older people with Alzheimer’s disease living in residential care facilities. Four studies reached “moderate” methodological quality and six “low”. The results showed that among older people with Alzheimer’s disease in residential care facilities, combined functional weight-bearing exercise over 12 months at an intended moderate intensity seems applicable for use regarding attendance and adverse events and there is some evidence that the exercise improves walking performance and reduces ADL decline. Furthermore, there is some evidence that walking exercise over 16 weeks performed individually, where the participant walks as far as possible during the session, reduces decline in walking performance, but adverse events need to be evaluated. In conclusion, among older people who are dependent in ADL, living in residential care facilities, and have an MMSE score of 10 or more, a high-intensity functional weight-bearing exercise programme is applicable for use and has positive long-term effects on functional balance, gait ability, and lower-limb strength and seems to reduce ADL decline related to indoor mobility. An intake of a protein-enriched energy supplement immediately after the exercise does not appear to increase the effect of the training. In people with dementia, the exercise programme may prevent decline in overall ADL performance, but continuous training may be needed to maintain that effect. The positive results regarding applicability and effects of combined functional weight-bearing exercise among people with dementia is confirmed when the scientific literature is systematically reviewed. It seems to be important that exercise interventions among people with dementia last for at least a few months and that the exercises are task-specific and intended to challenge the individual’s physical capacity. Whether physical exercise can improve cognitive functions among people with dementia remains unclear. There is a need for more exercise studies of high methodological quality among people with dementia disorders.

Motivational Interviewing to Promote Physical Activity in Breast Cancer Survivors

Asvat Patel, Yasmin 01 January 2013 (has links)
Abstract Despite documented health benefits, most breast cancer survivors (BCS) do not meet physical activity (PA) guidelines. Hence, evaluating diverse intervention approaches to promote PA in BCS is imperative. Motivational Interviewing (MI) offers a non-prescriptive, client-centered approach to PA promotion that has not been adequately evaluated in BCS. In this randomized-controlled trial, 66 Stage 0-IIIa BCS within three years post-treatment, insufficiently active and contemplating increasing PA were randomly assigned to a MI intervention or an active control condition. The MI intervention implemented motivational and behavior change strategies consistent with MI principles. The active control condition provided education and prescriptive recommendations on diet, PA, and stress management. Participants completed two in-person and one phone-based sessions over 4 weeks. Outcomes were assessed at baseline, 6-week, and 12-week follow-up. The primary outcome was efficacy of the MI intervention to promote PA. Contrary to the hypothesis that the MI intervention would be superior, PA improvements were evident for both groups, with 60% of all participants meeting PA guidelines at 12-week follow-up. Secondary outcomes involved intervention effects on depressive symptoms, fatigue, vigor, and aerobic fitness. Contrary to hypotheses, improvements in secondary outcomes were evident for both groups. Exploratory moderation analyses yielded no group differences in PA outcomes based on baseline activity level, perceived stress, age, or body mass index. Exploratory mediation analyses indicated that the relationships between group assignment and change in secondary outcomes were not mediated by change in PA. In analyses of the combined sample, higher baseline aerobic fitness predicted greater improvement in PA over time. Overall, results suggest that diverse intervention approaches can help promote PA in BCS. Future research should evaluate long-term maintenance of gains and theoretical mechanisms of the intervention effect.

Design and Validation of a Comprehensive Simulation-enhanced Training Curriculum for a Complex Minimally Invasive Operation

Zevin, Boris 02 April 2014 (has links)
Laparoscopic bariatric procedures are complex minimally invasive operations with a potential for substantial morbidity and mortality along the early part of a surgeon’s learning curve. Simulation-enhanced training can improve a surgeon's technical and non-technical performance and lessen the learning curves in the operating room. Unfortunately, despite the convincing evidence supporting the use of simulation in surgical education, there is still a gap in translation of knowledge and technical skills from the research environment into clinically relevant training curricula. The objective of this thesis was to design and validate a comprehensive simulationenhanced training curriculum that addressed cognitive knowledge, technical and non-technical skill in laparoscopic bariatric surgery. This objective was achieved using three experimental studies. The first study employed a modified Delphi methodology and an international panel of experts in surgical and medical education to develop a consensus-based framework for design, validation and implementation of simulation-enahnced training curricula in surgery. The second study used a modified Delphi methodology and an international panel of experienced bariatric surgeons to develop an objective scale for assessment of operative skill in laparoscopic gastric bypass procedure. This scale was feasible to use and had high inter-rater and test-retest reliability, as well as evidence of construct and concurrent validity. The third study used the previously developed consensus-based framework to design a comprehensive simulation-enhanced training curriculum for laparoscopic bariatric surgery. A prospective, single-blinded randomized controlled trial was used to compare the effectiveness of this curriculum in comparison to conventional surgery training. Surgery residents who were trained in this curriculum demonstrated superior technical skills, superior non-technical skills and enhanced safety in the operating room.
