Perceptions of a service redesign by adults living with type 2 diabetes
<b>Aim:</b> This article is a report of a study conducted to explore the perceptions of adults with type 2 diabetes towards the service redesign.
<b>Background:</b> Diabetes is reaching epidemic proportions and the management of this chronic illness is changing in response to this challenge. In the United Kingdom, there is ongoing restructuring of healthcare services for people with chronic illnesses to ensure that their general health and clinical needs are met predominantly in primary care.
<b>Method:</b> An explorative qualitative approach was used. Eight focus groups were conducted with 35 people with type 2 diabetes in one urban location between 2003 and 2004. Five focus groups were conducted with people who had recently experienced the restructured service and three groups with people who had up to 2 years' experience of the new service. Concurrent data collection and thematic analysis were conducted by three researchers and credibility and verification sought by feedback to participants.
<b>Findings:</b> Five main themes were identified: impact of living with diabetes; understanding diabetes; drivers for organizational change; care in context and individual concerns. Participants identified issues for ongoing development of the service.
<b>Conclusion:</b> People with type 2 diabetes appreciate their care management within the primary care setting where there has been investment in staff to deliver this care. Healthcare resources are required to support the development of staff and the necessary infrastructure to undertake management in primary care. Policy makers need to address the balance of resources between primary and secondary care

Weight-Loss Maintenance in Successful Weight Losers: Surgical vs. Non-Surgical Methods
Objective: As large weight losses are rarely achieved through any method except bariatric surgery, there have been no studies comparing individuals who initially lost large amounts of weight through bariatric surgery or non-surgical means. The National Weight Control Registry (NWCR) provides a resource for making such unique comparisons. This study compared the amount of weight regain, behaviors and psychological characteristics in NWCR participants who were equally successful in losing and maintaining large amounts of weight through either bariatric surgery or non-surgical methods. Design: Surgical participants (n=105) were matched with two non-surgical participants (n=210) on gender, entry weight, maximum weight loss and weight-maintenance duration, and compared prospectively over 1 year. Results: Participants in the surgical and non-surgical groups reported having lost approximately 56 kg and keeping ≥ 13.6 kg off for 5.5 ± 7.1 years. Both groups gained small but significant amounts of weight from registry entry to 1 year (P=0.034), but did not significantly differ in magnitude of weight regain (1.8 ± 7.5 and 1.7 ± 7.0 kg for surgical and non-surgical groups, respectively; P=0.369). Surgical participants reported less physical activity, more fast food and fat consumption, less dietary restraint, and higher depression and stress at entry and 1 year. Higher levels of disinhibition at entry and increased disinhibition over 1 year were related to weight regain in both groups. Conclusions: Despite marked behavioral differences between the groups, significant differences in weight regain were not observed. The findings suggest that weight-loss maintenance comparable with that after bariatric surgery can be accomplished through non-surgical methods with more intensive behavioral efforts. Increased susceptibility to cues that trigger overeating may increase risk of weight regain regardless of initial weight-loss method
Impacto da desidratação na geração de força de atletas de arco e flecha durante competição Indoor e Outdoor
INTRODUÇÃO: O arco e flecha é um esporte estático que requer força e resistência da parte superior do corpo, sendo que a habilidade do arqueiro é definida pela capacidade de atirar a flecha no alvo em um intervalo de tempo com precisão. A contração muscular gerada durante a execução do gesto esportivo propicia o aumento da temperatura corporal, da oxidação de glicose e da sudorese, podendo esta ser potencializada pelas condições climáticas à s quais o atleta é exposto. Todos estes fatores alteram a percepção de esforço e a própria geração de força, impondo um estresse negativo à performance. OBJETIVOS: Avaliar e relacionar o estado de hidratação de atletas de arco e flecha com alterações fisiológicas e de força intervenientes no rendimento competitivo. MÉTODOS: Participaram 11 arqueiros em duas competições distintas (indoor e outdoor). Foram mensurados parâmetros relacionados ao estado de hidratação, glicemia, percepção de esforço subjetivo e alteração na força de preensão palmar. RESULTADOS: Os atletas analisados apresentaram alterações significativas nos parâmetros relacionados ao estado hÃdrico em diferentes dias, provavelmente relacionadas à s condições climáticas adversas na competição outdoor (34ºC e 60% URA) em relação à competição indoor (22ºC e 90% URA). O mesmo não foi observado para a glicemia. CONCLUSÃO: Este trabalho é o primeiro a comprovar a relação direta entre fatores climáticos e de rendimento em arqueiros de alto nÃvel durante evento competitivo, assim como a evidenciar quais métodos não invasivos seriam os mais indicados para a avaliação do impacto destas alterações
Effects of a low carbohydrate weight loss diet on exercise capacity and tolerance in obese subjects
Dietary restriction and increased physical activity are recommended for obesity treatment. Very low carbohydrate diets are used to promote weight loss, but their effects on physical function and exercise tolerance in overweight and obese individuals are largely unknown. The aim of this study was to compare the effects of a very low carbohydrate, high fat (LC) diet with a conventional high carbohydrate, low fat (HC) diet on aerobic capacity, fuel utilization during submaximal exercise, perceived exercise effort (RPE) and muscle strength. Sixty subjects (age: 49.2+/-1.2 years; BMI: 33.6+/-0.5 kg/m2) were randomly assigned to an energy restricted (approximately 6-7 MJ, 30% deficit), planned isocaloric LC or HC for 8 weeks. At baseline and week 8, subjects performed incremental treadmill exercise to exhaustion and handgrip and isometric knee extensor strength were assessed. Weight loss was greater in LC compared with HC (8.4+/-0.4% and 6.7+/-0.5%, respectively; P=0.01 time x diet). Peak oxygen uptake and heart rate were unchanged in both groups (P>0.17). Fat oxidation increased during submaximal exercise in LC but not HC (P0.25). An LC weight loss diet shifted fuel utilization toward greater fat oxidation during exercise, but had no detrimental effect on maximal or submaximal markers of aerobic exercise performance or muscle strength compared with an HC diet. Further studies are required to determine the interaction of LC diets with regular exercise training and the long-term health effects.Grant D. Brinkworth, Manny Noakes, Peter M.
