No correlation among expressed emotion, anxiety, stress and weight loss in patients with overweight and obesity.

BACKGROUND: The onset of some types of obesity may correlate with specific familial relational patterns, and expressed emotion (EE), the family life's 'emotional temperature', may play a role in obesity treatment compliance and outcome. OBJECTIVE: The aim of this study is to address the current gap in the literature about EE and obesity, assessing EE in a sample of patients with overweight or obesity and their relatives. A further objective is to assess patients' weight loss, patients' and relatives' anxiety, perceived stress and their possible correlation with EE and diet compliance. DESIGN: A total of 220 patients with overweight or obesity and 126 relatives were recruited; their socio-demographic and clinical features were collected; and Level of Expressed Emotion Scale (LEE), State-Trait Anxiety Inventory 1 and 2 (STAI-Y1 and STAI-Y2) and Paykel Scale of Stressful Life Events were administered. RESULTS: Patients' baseline body mass index (BMI) was negatively correlated with educational level, but we failed to find any correlation between BMI and the other variables assessed. We found a positive correlation between EE median and stressful life events, as well as between median EE and state and trait anxiety. CONCLUSIONS: Our results seem to suggest that other factors than the psychological ones we investigated may play a role in treatment adherence and outcome in patients with overweight and obesity.

Effects of essential amino acid supplementation and rehabilitation on functioning in hip fracture patients: a pilot randomized controlled trial.

BACKGROUND: Physical exercise and nutrition seem to have a key role in the management of hip fracture patients. AIM: To evaluate the impact of a 2-month rehabilitative protocol combined with dietetic counseling, with or without essential amino acid supplementation, on functioning in hip fracture patients. METHODS: In this pilot randomized controlled study, we recruited patients aged more than 65 years, at 3 months after hip fracture. We randomly assigned the participants into two groups (A and B). Both groups performed a physical exercise rehabilitative programme (five sessions of 40 min/week for 2 weeks, followed by a home-based exercise protocol) and received a dietetic counseling; only group A was supplemented with two sachets of 4 g/day of essential amino acids (Aminotrofic®). We evaluated at baseline and after 2 months of intervention (T1): hand grip strength, Timed Up and Go, and Iowa Level of Assistance scale (ILOA). RESULTS: The 32 hip fracture patients (mean aged 79.03 ± 7.80 years) were allocated into two groups: group A (n = 16) and group B (n = 16). All the participants showed significant differences in all outcomes at T1 (p < 0.017). Sarcopenic patients in group A (n = 10) showed statistically significant differences in all the primary outcomes at T1 (p < 0.017), whereas sarcopenic patients in group B (n = 13) showed a significant reduction of ILOA only. In non-sarcopenic patients, we found no differences at T1 in all outcome measures. DISCUSSION: Hip fractures are a complex multifactorial condition of the elderly that determines devastating effects on functioning and independence. CONCLUSION: A multidisciplinary rehabilitative and nutritional intervention seems to be effective on functioning in hip fracture patients, in particular sarcopenic ones.

Cost-effectiveness of a disease-specific oral nutritional support for pressure ulcer healing.

BACKGROUND & AIMS: The Oligo Element Sore Trial has shown that supplementation with a disease-specific nutritional formula enriched with arginine, zinc, and antioxidants improves pressure ulcer (PU) healing in malnourished patients compared to an isocaloric-isonitrogenous support. However, the use of such a nutritional formula needs to be supported also by a cost-effectiveness evaluation. METHODS: This economic evaluation - from a local healthcare system perspective - was conducted alongside a multicenter, randomized, controlled trial following a piggy-back approach. The primary efficacy endpoint was the percentage of change in PU area at 8 weeks. The cost analysis focused on: the difference in direct medical costs of local PU care between groups and incremental cost-effectiveness ratio (ICER) of nutritional therapy related to significant study endpoints (percentage of change in PU area and ≥40% reduction in PU area at 8 weeks). RESULTS: Although the experimental formula was more expensive (mean difference: 39.4 Euros; P < 0.001), its use resulted in money saving with respect to both non-nutritional PU care activities (difference, -113.7 Euros; P = 0.001) and costs of local PU care (difference, -74.3 Euros; P = 0.013). Therefore, given its efficacy it proved to be a cost-effective intervention. The robustness of these results was confirmed by the sensitivity analyses. CONCLUSION: The use of a disease-specific oral nutritional formula not only results in better healing of PUs, but also reduces the costs of local PU care from a local healthcare system perspective.

A nutritional formula enriched with arginine, zinc, and antioxidants for the healing of pressure ulcers: a randomized trial.

BACKGROUND: Trials on specific nutritional supplements for the treatment of pressure ulcers (PUs) have been small, inconsistent in their formulations, or unsuccessful in controlling for total supplement calorie or protein content. OBJECTIVE: To evaluate whether supplementation with arginine, zinc, and antioxidants within a high-calorie, high-protein formula improves PU healing. DESIGN: Multicenter, randomized, controlled, blinded trial. (ClinicalTrials.gov: NCT01107197). SETTING: Long-term care and home care services. PATIENTS: 200 adult malnourished patients with stage II, III, and IV PUs. INTERVENTIONS: An energy-dense, protein-rich oral formula enriched with arginine, zinc, and antioxidants (400 mL/d) or an equal volume of an isocaloric, isonitrogenous formula for 8 weeks. MEASUREMENTS: The primary end point was the percentage of change in PU area at 8 weeks. Secondary end points included complete healing, reduction in the PU area of 40% or greater, incidence of wound infections, the total number of dressings at 8 weeks, and the percentage of change in area at 4 weeks. RESULTS: Supplementation with the enriched formula (n = 101) resulted in a greater reduction in PU area (mean reduction, 60.9% [95% CI, 54.3% to 67.5%]) than with the control formula (n = 99) (45.2% [CI, 38.4% to 52.0%]) (adjusted mean difference, 18.7% [CI, 5.7% to 31.8%]; P = 0.017). A more frequent reduction in area of 40% or greater at 8 weeks was also seen (odds ratio, 1.98 [CI, 1.12 to 3.48]; P = 0.018). No difference was found in terms of the other secondary end points. LIMITATION: Participation was restricted to patients who were malnourished, were able to drink oral supplements, and were living in long-term care institutions or receiving home care services. CONCLUSION: Among malnourished patients with PU, 8 weeks of supplementation with an oral nutritional formula enriched with arginine, zinc, and antioxidants improved PU healing.

Ketogenic diet: electrophysiological effects on the normal human cortex.

PURPOSE: To explore the cortical electrophysiology of the ketogenic diet (KD) in the normal human. KD is effective against refractory epilepsy, but its precise mechanism is obscure. At the transmitter level, an enhancement of GABA inhibition has often been proposed. METHODS: We studied eight healthy volunteers undergoing a "classic" KD for 2 weeks. We measured several biochemical variables at baseline (T0), after 1 week (T1) and 2 weeks (T2) of KD, then 3 months after the KD conclusion (T3). Ketosis was quantified as 24-h ketonuria. At the same time, we studied the motor cortical excitability by means of transcranial magnetic stimulation (TMS). We also quantitatively evaluated the EEG signal in search of frequency shifts over the rolandic areas. RESULTS: Significant (p < 0.05) neurophysiological changes appeared at T2. These consisted of a strengthening of short-latency cortical inhibition (SICI), a TMS index which is thought to reflect GABA-A inhibition in the cortex. Then, there was an enhancement of the beta EEG band over the perirolandic region, similar to that following administration of GABA-A agonists. All changes disappeared at T3. CONCLUSIONS: A standard, short-term KD affected the cortical physiology of the normal human. The main changes were an augmented SICI and an increased perirolandic beta EEG activity, which are compatible with a lower level of neural excitation within the cortex.
