    Get PDF
    BACKGROUND: A few and partial data are available on psychosocial morbidity among cancer patients in Mediterranean countries. As a part of a more general investigation (Southern European Psycho-Oncology Study-SEPOS), the rate of psychosocial morbidity and its correlation with clinical and cultural variables were examined in cancer patients in Italy, Portugal and Spain. METHODS: A convenience sample of cancer outpatients with good performance status and no cognitive impairment were approached. The Hospital Anxiety-Depression scale (HAD-S), the Mini-Mental Adjustment to Cancer scale (Mini-MAC), and the Cancer Worries Inventory (CWI) were used to measure psychological morbidity, coping strategies and concerns about illness. RESULTS: Of 277 patients, 34% had pathological scores ("borderline cases" plus "true cases") on HAD-S Anxiety and 24.9% on HAD-S Depression. Total psychiatric "caseness" was 28.5% and 16.6%, according to different HAD cut-offs (14 and 19, respectively). Significant relationships of HAD-S Anxiety, HAD-S Depression, HAD-S Total score, with Mini-MAC Hopeless and Anxious Preoccupation, and CWI score were found. No differences emerged between countries on psychosocial morbidity, while some differences emerged between the countries on coping mechanisms. Furthermore, Fatalism, Avoidance and marginally Hopeless were higher compared to studies carried out in English-speaking countries. LIMITATIONS: The relatively small sample size and the good performance status prevent us to generalize data on patients with different cancer sites and advanced phase of illness. CONCLUSIONS: One-third of the patients presented anxiety and depressive morbidity, with significant differences in characteristics of coping in Mediterranean countries in comparison with English-speaking countries

    Gabapentin and pregabalin for the acute post-operative pain management. A systematic-narrative review of the recent clinical evidences

    Get PDF
    Background: Gabapentin and pregabalin inhibit Ca2+ currents via high-voltage-activated channels containing the α2δ-1 subunit, reducing neurotransmitter release and attenuating the postsynaptic excitability. They are antiepileptic drugs successfully used also for the chronic pain treatment. A large number of clinical trials indicate that gabapentin and pregabalin could be effective as postoperative analgesics. This systematic-narrative review aims to analyse the most recent evidences regarding the effect of gabapentinoids on postoperative pain treatment. Methods: Medline, The Cochrane Library, EMBASE and CINHAL were searched for recent (2006-2009) randomized clinical trials (RCTs) of gabapentin-pregabalin for postoperative pain relief in adults. Quality of RCTs was evaluated according to Jadad method. Visual analogue scale (VAS), opioid consumption and side-effects (nausea, vomiting, dizziness and sedation) were considered the most important outcomes. Results: An overall of 22 gabapentin (1640 patients), 8 pregabalin (707 patients) RCTs and seven meta-analysis were involved in this review. Gabapentin provided better post-operative analgesia and rescue analgesics sparing than placebo in 6 of the 10 RCTs that administered only pre-emptive analgesia. Fourteen RCTs suggested that gabapentin did not reduce PONV when compared with placebo, clonidine or lornoxicam. Pregabalin provided better post-operative analgesia and rescue analgesics sparing than placebo in two of the three RCTs that evaluated the effects of pregabalin alone vs placebo. Four studies reported no pregabalin effects on preventing the PONV. Conclusion: Gabapentin and pregabalin reduce pain and opioid consumption after surgery in confront with placebo, but comparisons with other standard post-operative regimens are not sufficient. Gabapentin and pregabalin seem not to have any influence on the prevention of PONV

    Post-herpetic neuralgia is the most challenging and debilitating complication of herpes zoster in the immunocompetent host. Because the effect of treatment is disappointing once the syndrome has developed, it is important to know which factors predict post-herpetic neuralgia occurrence to facilitate selection of herpes zoster patients with a higher risk of developing neuralgia and undertake preventative strategies. The present study aimed at identifying demographic, clinical and psychosocial correlates of post-herpetic neuralgia in a sample of 219 immunocompetent patients, who were examined by dermatologists in private practice in Italy and who completed a questionnaire designed to evaluate their clinical and psychosocial profile at the time of clinical diagnosis of herpes zoster and at a follow-up visit 6 months later. In a univariate analysis, post-herpetic neuralgia was associated significantly with older age, longer duration of prodromal pain, greater acute pain intensity, greater extent of rash, presence of abnormal sensations and use of systemic antiviral therapy. Compared to the values at herpes zoster onset, at the follow-up visit patients with post-herpetic neuralgia presented with similar high mean scores of pain intensity, anxiety and depression and greatly reduced quality of life, whereas patients without neuralgia presented with improved scores. In a multivariate model, older age, greater acute pain intensity, greater extent of rash and longer duration of prodromal pain were independently associated with post-herpetic neuralgia. The results of this study may help physicians to identify patients with a higher risk of developing post-herpetic neuralgia and undertaking preventative strategies

    Tissue and circulating microRNAs as biomarkers of response to obesity treatment strategies

    Get PDF
    Background: Obesity, characterized by an increased amount of adipose tissue, is a metabolic chronic alteration which has reached pandemic proportion. Lifestyle changes are the first line therapy for obesity and a large variety of dietary approaches have demonstrated efficacy in promoting weight loss and improving obesity-related metabolic alterations. Besides diet and physical activity, bariatric surgery might be an effective therapeutic strategy for morbid obese patients. Response to weight-loss interventions is characterised by high inter-individual variability, which might involve epigenetic factors. microRNAs have critical roles in metabolic processes and their dysregulated expression has been reported in obesity. Aim: The aim of this review is to provide a comprehensive overview of current studies evaluating changes in microRNA expression in obese patients undergoing lifestyle interventions or bariatric surgery. Results: A considerable number of studies have reported a differential expression of circulating microRNAs before and after various dietary and bariatric surgery approaches, identifying several candidate biomarkers of response to weight loss. Significant changes in microRNA expression have been observed at a tissue level as well, with entirely different patterns between visceral and subcutaneous adipose tissue. Interestingly, relevant differences in microRNA expression have emerged between responders and non-responders to dietary or surgical interventions. A wide variety of dysregulated microRNA target pathways have also been identified, helping to understand the pathophysiological mechanisms underlying obesity and obesity-related metabolic diseases. Conclusions: Although further research is needed to draw firm conclusions, there is increasing evidence about microRNAs as potential biomarkers for weight loss and response to intervention strategies in obesity

    Temporal trends in the cardiorespiratory fitness of 2,525,827 adults between 1967 and 2016

    Objective To estimate international and national temporal trends in the cardiorespiratory ftness (CRF) of adults, and to examine relationships between trends in CRF and trends in health-related, socioeconomic, and environmental indicators. Methods Data were obtained from a systematic search of studies that explicitly reported temporal trends in the CRF of apparently healthy adults aged 18–59 years. Sample-weighted temporal trends were estimated using best-ftting regression models relating the year of testing to mean CRF. Post-stratifed population-weighted mean changes in percent and standardized CRF were estimated. Pearson’s correlations were used to describe associations between linear trends in CRF and linear trends in health-related, socioeconomic, and environmental indicators. Results 2,525,827 adults representing eight high- and upper-middle-income countries between 1967 and 2016 collectively showed a moderate decline of 7.7% (95% CI −8.4 to −7.0) or 1.6% per decade (95% CI −1.7 to −1.5). Internationally, CRF improved in the 1960s and 1970s, and progressively declined at an increasing rate thereafter. Declines were larger for men than for women, and for young adults (\u3c40 \u3eyears) than for middle-aged adults (≥40 years). All countries experienced declines in CRF with a very strong negative correlation between CRF trends and obesity trends. Conclusions There has been a meaningful decline in the CRF of adults since 1980, which has progressively increased in magnitude over time, suggestive of a corresponding decline in population health. Continuous national and international surveillance systems are needed in order to monitor health and ftness trends, especially among low- and middle-income countries for which data do not currently exist.

    Get PDF
    The application of ceramic protective coatings to the metallic interconnects in solid oxide cells (SOCs) is a viable and effective method to limit interconnect degradation issues. This featured letter provides a critical overview of the main outcomes of current research on the use of the electrophoretic deposition (EPD) technique to produce protective coatings for SOC metallic interconnects, specifically focusing on different approaches to stabilise spinel-based suspensions, as well as the possible sintering procedures. The protective properties of EPD coatings are reviewed and discussed in terms of oxidation kinetics and area specific resistance evaluation

    MicroRNA modulation by dietary supplements in obesity

    Get PDF
    The prevalence of obesity has dramatically increased over the last decades. Weight loss obtained through diet and exercise leads to a significant decrease in morbidity and mortality. Recently, there has been growing interest in the possible beneficial effects of dietary supplements (DSs), including polyphenols, fatty acids, and other plant-derived substances, as adjuvants in the management of obesity and metabolic diseases. Specifically, polyphenols, widely spread in vegetables and fruits, significantly modulate adipose tissue activities, contrasting inflammation and improving insulin sensitivity in preclinical and clinical studies. Remarkably, polyphenols are involved in complex microRNA networks, which play crucial roles in metabolic processes. The administration of different polyphenols and other plant-derived compounds led to significant changes in the microRNA expression profile in peripheral tissues in a growing number of preclinical studies. In particular, these compounds were able to revert obesity-induced microRNA dysregulation, leading to the inhibition of adipogenesis and the induction of weight loss. Furthermore, through microRNA modulation, they attenuated key metabolic alterations, including insulin resistance and lipid anomalies, in animal models of obesity. Some of them were also able to reduce proinflammatory cytokines in adipose tissue. The aim of this review is to summarize current evidence about the effect of plant-derived DSs on microRNA expression in obesity
