Evolução do estado nutricional de pacientes desnutridos ou com excesso de peso candidatos a transplante pulmonar Evolution of nutritional status in lung transplant candidates who are initially malnourished or overweight

Estudo retrospectivo, que avaliou a evolução do estado nutricional, por meio de antropometria, de candidatos a transplante pulmonar desnutridos ou com excesso de peso. Foram incluídos pacientes com índice de massa corpórea (IMC) < 17 kg/m² (desnutrido, n = 10) ou IMC > 27 kg/m² (sobrepeso, n = 20) no momento da avaliação inicial. Estes pacientes foram submetidos por três consultas com um nutricionista (intervenções nutricionais). Não houve diferenças significantes nas variáveis antropométricas após as intervenções no grupo desnutrido. Porém, os resultados do grupo sobrepeso mostraram o impacto positivo da intervenção nutricional no peso, IMC e circunferência da cintura dos pacientes.<br>A retrospective study using anthropometric data to assess the evolution of nutritional status in lung transplant candidates who are initially malnourished or overweight. We included patients with an initial body mass index (BMI) < 17 kg/m² (malnourished, n = 10) or > 27 kg/m² (overweight, n = 20). Each patient subsequently had three appointments with a nutritionist (nutritional interventions). In the malnourished group, there were no significant post-intervention changes in the anthropometric variables. In the overweight group, however, nutritional intervention had a positive impact on weight, BMI and waist circumference

Remove, rotate, and reimplant: a novel technique for the management of exposed porous anophthalmic implants in eviscerated patients

PURPOSE: To describe and to evaluate a new and relatively easy technique for porous implant exposure repair. METHODS: Eleven patients with exposed porous orbital implants after evisceration were included in this study. Five patients with large exposures (diameter>7 mm) and six patients with small exposures of orbital implants (diameter<7 mm) that persisted despite posterior vaulting of the prosthesis and usage of antibiotics and steroids for more than 6 weeks, underwent revision surgery with the remove-rotate-reimplant technique (3R technique). Negative microbiological culture taken from the exposed socket surface before surgery was the major inclusion criterion. Five patients with insufficient conjunctival tissue also underwent additional mucosa or hard palate grafting of the defect in addition to the remove-rotate-reimplant procedure. RESULTS: Patients have been followed up for more than 18 months (ranging from 18–30 months). None of them received motility peg insertion after repair. Implant reexposure was detected in one patient during the follow-up period, which was managed by dermis fat grafting with implant removal. CONCLUSION: The remove-rotate-reimplant technique is an effective surgical method for repairing exposed porous anophthalmic implants after evisceration with a 90% success in this study. It avoids the removal of the implant from the sclera, which is a traumatic procedure that may lead to the tearing and loss of scleral tissue covering the implant. Saving the porous implant and scleral cover reduces the surgical time and cost

Social exchange in collaborative innovation: maker or breaker

Collaborations in innovation work between competitors have become a common practice in the information and communication technology sector (ICT), and substantial investments are made in such collaborations. Significant rationales for these collaborations include the high expectations placed on rapid and front-edge technology development and business exploitation. However, there is often a failure to reach the expected outcomes of such collaborations. This may be explained not only by the challenges and obstacles in technology development but also by the social relations within the collaborations. The purpose of this study is to explore the role of social exchange in the outcomes of early-stage innovation collaborations. More specifically, we explore the social facilitators of exchange and how such facilitators may influence collaboration outcomes. Social exchange theory is used for this purpose. This longitudinal study is based on a 3-year collaboration project for innovation using qualitative methods (29 interviews, observations of 7 project meetings). Three phases of social exchange in the collaboration are empirically identified: the dating phase, brainstorming phase, and decision phase. Three social facilitators of social exchange within these phases are conceptualized: trust, commitment, and congruence. Further, direct contacts are conceptualized as a social accelerator fueling these social facilitators. This study advances understanding of social facilitators in social exchange and their significance with regard to success/failure outcomes. Risks of lock-in situations in collaborations for innovation are outlined in a knowledge exchange paradox
