RESUMO
BACKGROUND: Health-related quality of life (QoL) is a measure that allows us to know the patient's perception of well-being and how it is affected by their disease and treatments. In cancer patients, sarcopenia has been associated with low scores on various instruments used to assess the QoL; however, little information is available on the effects of sarcopenia and sarcopenic obesity on the QoL of patients with head and neck cancer (H&NC). METHODS: In this cross-sectional study with 71 H&NC patients aged between 40 and 80 years, we describe the scores on the instruments EORTC QLQ C-30 and EORTC QLQ-H&N35 according to the sarcopenia phenotype (NSG, nonsarcopenic group; SG, sarcopenic group; and SOG, sarcopenic obesity group), hand-grip strength, gait speed, total lymphocyte count, albumin, cholesterol and C-reactive protein, and the relationships between these variables. RESULTS: The prevalence of sarcopenia and sarcopenic obesity was 48% and 28%, respectively. The QoL analysis showed that NSG had higher scores on the physical functioning scale [NSG 93 (83-100); SG 73 (52-88); SOG 83 (53-93), P = .009] and lower scores on the fatigue scale [NSG 11 (0-22); S 39 (30-67); SOG 44 (14-56); P = .004]. The NSG had a higher hand-grip strength (31.1 kg) than SG (24.1 kg, P = .007) and SOG (26.3 kg, P = .001), and a lower C-reactive protein. The SG and SOG showed no differences between them. CONCLUSIONS: Patients with sarcopenia or sarcopenic obesity have lower physical performance and a higher level of fatigue than nonsarcopenic patients. This loss of function can maintain or worsen sarcopenia due to the patient's self-restraint in physical exertion that encourages an increase in muscle tissue.
RESUMO
Infection plays a critical role in health care and impacts the cost of the treatment of diabetic foot ulcers (DFU). To examine the cost reduction associated with the multidisciplinary treatment of infected DFU (IDFU) by obtaining early (ie, within 48 hours of admission) microbiological culture results, a descriptive, longitudinal study was conducted. Data were collected prospectively from patient medical charts of a cohort of 67 patients (mean age, 56.14 ± 12.3 years; mean duration of diabetes, 14.95 ± 8 years) with IDFU treated at a Mexican public health facility from January 1 to April 30, 2010. Information included demographic data (age, gender, marital status, time elapsed since first diagnosis of diabetes mellitus type 2 [DM2]), and the following clinical records: Wagner classification, bacterium type, antimicrobial resistance, length of hospital stay, and the antibiotic schedule utilized, as well as number and type of laboratory tests, medications, intravenous therapy, surgical and supportive treatment, type and number of specialists, and clinical outcome. Microcosting was used to calculate the unit cost of each medical treatment element. Using the Monte Carlo and Markov predictive simulation economical models, cost reduction associated with early identification of the specific microorganism through bacterial culture in IDFU was estimated. Based on the statistical results, differences between real and estimated costs when including early microbiological culture were identified and the number and type of most common species of infectious bacteria were detected. The total cost observed in the patient cohort was $502 438.04 USD, mean cost per patient was $7177.69 ± $5043.51 USD, and 72.75% of the total cost was associated with the hospital stay length. The cost of the entire treatment including antibiotics was $359 196.16 USD; based on the simulation of early microbiological culture, the model results showed cost could be reduced by 10% to 25% (in this study, the cost could be as low as $304 624.63 USD). The use of early microbiological cultures on IDFU to determine the appropriate antibiotic can reduce treatment costs by >30% if hospital stay is part of the consideration.
