Treatment of proximal interphalangeal joint flexion contracture: Combined static and dynamic orthotic intervention compared with other therapy intervention: randomized controlled trial

Purpose To test the effectiveness of static and dynamic orthoses using them as an exclusive treatment for proximal interphalangeal (PIP) joint flexion contracture compared with other hand therapy conservative treatments described in the literature. Methods 60 patients who used orthoses were compared with a control group that received other hand therapy treatments. Clinical assessments were measured before the experiment and 3 months after and included active PIP joint extension and function. Results A significant improvement in the extension active range of motion at the PIP joint in the second measurement was found in both groups, but it was significantly greater in the experimental group. Improvement in function (Disabilities of the Arm, Shoulder, and Hand score) between the first and second assessment was similar in the control and experimental groups. Conclusions Using night progressive static and daily dynamic orthoses as an exclusive treatment during the proliferative phase led to significant improvements in the PIP joint active extension, but the improvement did not correlate with increased function as perceived by the patient.

Nutrition intervention approaches to reduce malnutrition in oncology patients: A systematic review

Purpose Malnutrition is a very common problem in oncology patients and is associated with many negative consequences including poorer prognosis, quality of life and survival. However, malnutrition in oncology patients is often overlooked although there is growing evidence showing that it can be prevented or reduced through nutrition intervention. This paper aims to provide an updated review on the effectiveness of different nutrition intervention approaches on nutrition status outcomes in oncology patients. Methods Randomised controlled trials (RCTs) published between 1994 and 2014 which examined the effects of nutrition intervention approaches—in particular, nutrition counselling (NC), oral nutrition supplements (ONS) and tube feeding (TF)—on nutrition status outcomes of oncology patients were identified and reviewed. Results Thirteen papers from 11 RCTs with a total of 1077 participants were included. The intervention approaches included NC (four studies), NC + ONS (five studies), ONS (three studies) and TF (three studies). The various results suggest that NC with or without ONS was associated with consistent improvements in several nutrition status outcomes. On the other hand, ONS and TF were associated with inconsistent improvements in few aspects of nutrition status outcomes. Conclusions The referral of oncology patients for NC is recommended given the strong evidence of its beneficial effects on the prevention and reduction of malnutrition. Other forms of nutrition support including ONS and TF may then be included if deemed suitable and necessary for the individual.

A survey of process hygiene in the Sri Lankan prawn industry. 2. The hygiene status of personnel

Of 262 personnel tested, 137 (52%) were found to be positive for Staphylococcus aureus. Among individual companies the prevalence of S. aureus ranged from 92% (Company No. 1) to 22% (Company No. 2). Although five companies provided a sanitiser hand-dip, this was found to be ineffective for the control of S. aureus. Provision of hand-washing facilities, of protective clothing and of toilet facilities was found to be inadequate for an export food industry.

Automatic 2D Hand Tracking in Video Sequences

In gesture and sign language video sequences, hand motion tends to be rapid, and hands frequently appear in front of each other or in front of the face. Thus, hand location is often ambiguous, and naive color-based hand tracking is insufficient. To improve tracking accuracy, some methods employ a prediction-update framework, but such methods require careful initialization of model parameters, and tend to drift and lose track in extended sequences. In this paper, a temporal filtering framework for hand tracking is proposed that can initialize and reset itself without human intervention. In each frame, simple features like color and motion residue are exploited to identify multiple candidate hand locations. The temporal filter then uses the Viterbi algorithm to select among the candidates from frame to frame. The resulting tracking system can automatically identify video trajectories of unambiguous hand motion, and detect frames where tracking becomes ambiguous because of occlusions or overlaps. Experiments on video sequences of several hundred frames in duration demonstrate the system's ability to track hands robustly, to detect and handle tracking ambiguities, and to extract the trajectories of unambiguous hand motion.

Monitoring treatment fidelity in a randomised controlled trial of a complex intervention.

Aim. This paper is a report of a study to describe how treatment fidelity is being enhanced and monitored, using a model from the National Institutes of Health Behavior Change Consortium. Background. The objective of treatment fidelity is to minimize errors in interpreting research trial outcomes, and to ascribe those outcomes directly to the intervention at hand. Treatment fidelity procedures are included in trials of complex interventions to account for inferences made from study outcomes. Monitoring treatment fidelity can help improve study design, maximize reliability of results, increase statistical power, determine whether theory-based interventions are responsible for observed changes, and inform the research dissemination process. Methods. Treatment fidelity recommendations from the Behavior Change Consortium were applied to the SPHERE study (Secondary Prevention of Heart DiseasE in GeneRal PracticE), a randomized controlled trial of a complex intervention. Procedures to enhance and monitor intervention implementation included standardizing training sessions, observing intervention consultations, structuring patient recall systems, and using written practice and patient care plans. The research nurse plays an important role in monitoring intervention implementation. Findings. Several methods of applying treatment fidelity procedures to monitoring interventions are possible. The procedure used may be determined by availability of appropriate personnel, fiscal constraints, or time limits. Complex interventions are not straightforward and necessitate a monitoring process at trial stage. Conclusion. The Behavior Change Consortium’s model of treatment fidelity is useful for structuring a system to monitor the implementation of a complex intervention, and helps to increase the reliability and validity of evaluation findings.

Fumonisin B-1 as a Urinary Biomarker of Exposure in a Maize Intervention Study Among South African Subsistence Farmers

Background: The consumption of maize highly contaminated with carcinogenic fumonisins has been linked to high oesophageal cancer rates. The aim of this study was to validate a urinary fumonisin B-1 (UFB1) biomarker as a measure of fumonisin exposure and to investigate the reduction in exposure following a simple and culturally acceptable intervention.

Methods: At baseline home-grown maize, maize-based porridge, and first-void urine samples were collected from female participants (n = 22), following their traditional food practices in Centane, South Africa. During intervention the participants were trained to recognize and remove visibly infected kernels, and to wash the remaining kernels. Participants consumed the porridge prepared from the sorted and washed maize on each day of the two-day intervention. Porridge, maize, and urine samples were collected for FB1 analyses.

Results: The geometric mean (95% confidence interval) for FB1 exposure based on porridge (dry weight) consumption at baseline and following intervention was 4.84 (2.87-8.14) and 1.87 (1.40-2.51) mg FB1/kg body weight/day, respectively, (62% reduction, P < 0.05). UFB1C, UFB1 normalized for creatinine, was reduced from 470 (295-750) at baseline to 279 (202-386) pg/mg creatinine following intervention (41% reduction, P = 0.06). The UFB1C biomarker was positively correlated with FB1 intake at the individual level (r - 0.4972, P < 0.01). Urinary excretion of FB1 was estimated to be 0.075% (0.054%-0.104%) of the FB1 intake.

Conclusion: UFB1 reflects individual FB1 exposure and thus represents a valuable biomarker for future fumonisin risk assessment.

Impact: The simple intervention method, hand sorting and washing, could positively impact on food safety and health in communities exposed to fumonisins. Cancer Epidemiol Biomarkers Prev; 20(3); 483-9. (C)2011 AACR.

Simple intervention method to reduce fumonisin exposure in a subsistence maize-farming community in South Africa

In the Centane magisterial area of South Africa, high rates of oesophageal cancer have been associated with home-grown maize contaminated with fumonisins. The aim of this study was to implement a simple intervention method to reduce fumonisin exposure in a subsistence-farming community. The hand-sorting and washing procedures, based on traditional maize-based food preparation practices, were previously customised under laboratory-controlled conditions. Home-grown maize and maize-based porridge collected at baseline were analysed for fumonisin B1, B2 and B3. The geometric mean (95% confidence interval) of fumonisin contamination in the home-grown maize at baseline was 1.67 (1.21-2.32) mg kg-1 and 1.24 (0.75-2.04) mg kg -1 (dry weight) in the porridge. Fumonisin exposure was based on individual stiff porridge consumption and the specific fumonisin levels in the porridge (dry weight) consumed. Porridge (dry weight) consumption at baseline was 0.34 kg day-1 and fumonisin exposure was 6.73 (3.90-11.6) mu g kg-1 body weight day-1. Female participants (n = 22) were trained to recognise and remove visibly infected/damaged kernels and to wash the remaining maize kernels. The discarded kernels represented 3.9% by weight and the fumonisins varied from 17.1 to 76.9 mg kg-1. The customised hand-sorting and washing procedures reduced fumonisin contamination in the maize and porridge by 84 and 65%, respectively. The intervention reduced fumonisin exposure by 62% to 2.55 (1.94-3.35) mu g kg-1 body weight day-1. This simple intervention method has the potential to improve food safety and health in subsistence-farming communities consuming fumonisin-contaminated maize as their staple diet.

Minimal intervention dentistry and older patients Part 1: Risk assessment and caries prevention

Ten million people in the UK today are aged over 65. The latest projections estimate that there will be 5 1/2 million more people aged 65 and older in the next 20 years. This projected pattern of population ageing will have profound consequences for dentistry. Minimal intervention dentistry (MID) is a modern evidence-based approach to caries management in dentate patients that uses the 'medical model' whereby disease is controlled by the 'oral physician'. This approach offers considerable benefits over conventional dentistry for older patients. It encourages patients to be responsible for their oral health through the provision of both knowledge and motivation. MID encompasses risk assessment for dental disease, early detection and control of disease processes, and minimally invasive treatment. 

Clinical Relevance: Risk assessment tools can aid the general dental practitioner and the patient to develop a suitable caries prevention programme for that individual and reduce the need for future operative intervention.

Feasibility and acceptability of an exergame intervention for schizophrenia

Objectives To evaluate the feasibility and acceptability of an exergame intervention as a tool to promote physical activity in outpatients with schizophrenia. Design Feasibility/Acceptability Study and Quasi-Experimental Trial. Method Sixteen outpatients with schizophrenia received treatment as usual and they all completed an 8-week exergame intervention using Microsoft Kinect® (20 min sessions, biweekly). Participants completed pre and post treatment assessments regarding functional mobility (Timed Up and Go Test), functional fitness performance (Senior Fitness Test), motor neurological soft signs (Brief Motor Scale), hand grip strength (digital dynamometer), static balance (force plate), speed of processing (Trail Making Test), schizophrenia-related symptoms (Positive and Negative Syndrome Scale) and functioning (Personal and Social Performance Scale). The EG group completed an acceptability questionnaire after the intervention. Results Attrition rate was 18.75% and 69.23% of the participants completed the intervention within the proposed schedule. Baseline clinical traits were not related to game performance indicators. Over 90% of the participants rated the intervention as satisfactory and interactive. Most participants (76.9%) agreed that this intervention promotes healthier lifestyles and is an acceptable alternative to perform physical activity. Repeated-measures MANOVA analyses found no significant multivariate effects for combined outcomes. Conclusion This study established the feasibility and acceptability of an exergame intervention for outpatients with schizophrenia. The intervention proved to be an appealing alternative to physical activity. Future trials should include larger sample sizes, explore patients' adherence to home-based exergames and consider greater intervention dosage (length, session duration, and/or frequency) in order to achieve potential effects.

Intervention policière en milieu scolaire : expérience et point de vue des acteurs

Contexte et objectif. Afin de résorber le problème de la violence en milieu scolaire, de nombreux programmes et partenariats « police-école » ont vu le jour. Malgré la popularité de ces initiatives, les évaluations établissent toutefois que leurs effets sur la violence et la délinquance sont plutôt triviaux. Récemment, le programme de prévention « Unité sans violence » a été implanté dans plusieurs écoles de la région métropolitaine de Montréal et une évaluation préliminaire rapporte que son introduction fut suivie d’une baisse significative de la victimisation. À l’aide d’une approche mixte, l’objectif de ce mémoire est d’explorer la pertinence des concepts du rôle paradoxale et de l’intervention en contexte d’autorité afin de mieux comprendre les interactions entre les partenaires du programme et d’identifier de nouvelles pistes permettant de mieux comprendre les effets des programmes policiers en milieu scolaire. Méthodologie. La recherche repose sur des données qualitatives et quantitatives. D’une part, des entretiens semi-directifs ont été réalisés auprès des intervenants (policiers, enseignants et éducateurs spécialisés) afin de recueillir leur point de vue et expérience par rapport au programme. D’autre part, des questionnaires ont été administrés aux élèves de cinquième et sixième année de 20 écoles, ce qui a permis de documenter leur perception des policiers. Résultats. Les résultats aux entrevues suggèrent que les rôles d’aidant du policier et celui plus répressif s’inscrivent en continuité plutôt qu’en contradiction. Les rôles d’éducateur et de « grand frère » du policier seraient très bien reçus par les élèves. L’expérience des policiers, leur approche empathique et personnalisée ainsi que leur intérêt pour le travail communautaire apparaissent comme des éléments clés du bon déroulement du programme. Les résultats aux questionnaires montrent d’ailleurs que les élèves ont une perception très favorable des policiers. Conclusion. Les concepts de rôle et d’intervention en contexte d’autorité apparaissent comme des éléments clés qui devraient être intégrés à toute recherche évaluative visant à mieux comprendre l’effet des programmes policiers sur la délinquance. De plus, d’autres évaluations quantitatives du programme « Unité sans violence » sont nécessaires pour mieux comprendre l’influence de certaines de ses composantes, soit le renforcement positif, l’étalement du programme tout au long de l’année scolaire, le rôle des enseignants dans la transmission du message et l’exposition continue au programme entre la cinquième et sixième année.

Intervention dans le processus de réinsertion sociale au Québec : une étude du point de vue des agents de réinsertion sociale en collectivité

Ce mémoire a pour objectif de comprendre l’expérience de travail des agents œuvrant en réinsertion sociale auprès de condamnés provinciaux en collectivité au Québec. Plus précisément, cette recherche souhaite saisir le rôle exercé par ces agents, dans un contexte où ils exercent un double mandat de sécurité publique et de réinsertion sociale. L’étude tente aussi de mettre en lumière leurs pratiques de travail, inscrites dans une logique de gestion efficace des risques. Enfin, ce mémoire vise à comprendre la place qu’occupe la réinsertion sociale dans le cadre de leur travail. Pour ce faire, l’approche qualitative a permis de mener quinze (15) entretiens auprès d’agents de probation et d’intervenants issus du secteur communautaire responsables de la surveillance de justiciables provinciaux en collectivité. Deux (2) thèmes principaux émergent de ces entrevues. D’une part, Le travail est décrit par les participants en regard du double rôle exercé, des responsabilités légales et cliniques qui leur incombent, et de l’intervention centrée sur le risque et la réinsertion sociale auprès des contrevenants. D’autre part, Le contexte de travail réfère au partenariat établi entre les intervenants, au recours aux outils actuariels, ainsi qu’aux instances modulant leurs pratiques de travail : les médias, la Commission québécoise des libérations conditionnelles et les Services correctionnels du Québec. Il ressort de nos analyses que la sécurité publique par la gestion efficace des risques se manifeste par une forme de rationalisation des pratiques de travail et par l’intégration d’un rôle de contrôle. Il appert cependant que ces deux (2) aspects sont motivés avant tout par le désir de venir en aide à la population contrevenante. Il résulte finalement de l’étude que la réinsertion sociale ne constitue qu’un objectif de l’intervention parmi d’autres. Les participants doivent jongler avec ces diverses finalités afin de s’ajuster à l’acteur principal de leur travail : le contrevenant.

Psychological intervention in an only multifamily session at an Acute Care Unit of a psychiatric clinic

This article provides an overview of the psychological intervention in a Unit Care of Mental Health. The objectives and therapeutic actions to follow are defined through the participation of an interdisciplinary team and networking; it includes support groups and, especially, the families of patients that suffer a severe mental disorder. The materials and resources used were weekly sessions of one hour and forty minutes, for two years of monitoring (2005-2007). The study population consists of families of patients with different pathologies, which are in the Intensive Care Unit. In terms of design, it is made a qualitativeanalysis of 100 field day formats, and fills a matrix of content analysis. It is reviewed the objectives, the approach Multi-Focus, methodology, used techniques, the procedures developed and the feedback given at each session. The findings from this study show that mental disorders are related to the environment in which the patient is developed and complex social process. They also suggest a greater need for psychiatric patient care and its networks, timely and relevantly. By the other hand, it shows the importance of increasing efforts to make available in the field of mental health brief strategic interventions in interdisciplinary teams, it is appropriate a psycho educational and therapeutic approach in which the actions are coordinated at different levels.

Mão em garra: uma proposta de intervenção terapêutica ocupacional para hansenianos

A hanseníase é uma doença infecciosa crônica, granulomatosa, de curso lento, causada pelo Mycobacterium Leprae. O bacilo acomete principalmente os nervos periféricos, causando lesões na face, mãos e pés, que podem gerar incapacidades físicas severas que contribuem para a instalação de padrões deformantes e incapacidades. A lesão do tipo mão em garra é uma sequela que pode ser observada em pacientes com lesões ao nível dos membros superiores sendo muito incapacitante, dificultando a realização das atividades de vida diária destes indivíduos e consequentemente prejudicando sua qualidade de vida e satisfação pessoal. Estas lesões geram repercussões no contexto de vida do indivíduo contribuindo para a instalação de alterações nos aspectos psicoemocionais, além do estigma próprio da doença. A intervenção terapêutica ocupacional utilizando a tecnologia assistiva de baixo custo para auxílio nas atividades de vida diária de pacientes com mão em garra objetiva a minimização dos déficits funcionais apresentados durante a utilização de adaptações funcionais utilizadas na realização de suas atividades cotidianas como alimentação, higiene pessoal e vestuário. A intervenção realizou-se através da aplicação de um protocolo de avaliação em Terapia Ocupacional conhecido como Medida Canadense de Desempenho Ocupacional (COPM) que mede o grau de desempenho e Satisfação do paciente ao realizar suas atividades de vida diária. O protocolo foi aplicado inicialmente junto aos pacientes coletando dados sobre a realização das suas atividades de vida diária sem a utilização de recursos de tecnologia assistiva. A aplicação do protocolo baseou-se na definição de cinco problemas comuns a todos os participantes, revelando graus muito baixos de desempenho e satisfação obtidos durante a realização das atividades avaliadas. Posteriormente realizou-se o processo de prescrição, confecção e treinamento das adaptações desenvolvidas para cada paciente, somando-se um total de cento e vinte aparelhos (120) desenvolvidos. Aplicou-se novamente o mesmo protocolo com os mesmos pacientes abordando os mesmos problemas após a realização de um período de treinamento das adaptações funcionais desenvolvidas, comparando-se os dados coletados no primeiro e segundo COPM. Comparando-se aos dados iniciais apresentados, os dados coletados na segunda avaliação do COPM apontaram um aumento significativo do grau de desempenho e satisfação dos pacientes além de ganho funcional. Concluí-se com esta pesquisa que a proposta de intervenção terapêutica ocupacional utilizando equipamentos de tecnologia assistiva de baixo custo (adaptações) é viável, possui resultados satisfatórios e favorece um grande alcance social devido à redução de custos dos dispositivos desenvolvidos.

Pain and swelling after periapical surgery related to oral hygiene and smoking

OBJECTIVES: To evaluate pain and swelling during the first week after periapical surgery and its relation to patient age, gender, oral hygiene, and smoking. STUDY DESIGN: One hundred two patients (31 men and 71 women) with a mean age of 40.2 years underwent periapical surgery. Age, gender, and oral hygiene and cigarette smoking before and during the postoperative course were noted. Pain and swelling scores were recorded on a descriptive 4-point scale at 2, 6, and 12 hours after surgery, and each day thereafter for 1 week. The data were statistically evaluated for significant differences. RESULTS: The highest intensity of pain occurred during the first 48 hours, and swelling peaked on the second postoperative day. Patient age and gender had no significant effect on postoperative symptoms (P > .05). Patients with poor oral hygiene before surgery presented greater pain and swelling during the first postsurgical hours, and smokers before surgery also suffered more pain. The number of cigarettes smoked in the postoperative period and oral hygiene after surgery had no effect on pain or inflammation (P > .05). CONCLUSIONS: Periapical surgery caused little pain and moderate swelling during the first 2 days after the intervention; these findings were more distinct in patients with poor oral hygiene before surgery and in smokers.
