Synergistic beneficial effects of DHA + EVOO supplementation are associated with the activation/inactivation of key transcription factors involved in the above-mentioned processes. Data presented indicate that dietary supplementation with DHA + EVOO drastically reduces the development of nonalcoholic fatty liver disease.
Pharmacological therapy for nonalcoholic fatty liver disease (NAFLD) is not approved at the present time. For this purpose, the effect of combined eicosapentaenoic acid (EPA; 50 mg/kg/day) modulating hepatic lipid metabolism and hydroxytyrosol (HT; 5 mg/kg/day) exerting antioxidant actions was evaluated on hepatic steatosis and oxidative stress induced by a high-fat diet (HFD; 60% fat, 20% protein, and 20% carbohydrates) compared to a control diet (CD; 10% fat, 20% protein, and 70% carbohydrates) in mice fed for 12 weeks. HFD-induced liver steatosis (i) was reduced by 32% by EPA, without changes in oxidative stress-related parameters and mild recovery of Nrf2 functioning affording antioxidation and (ii) was decreased by 42% by HT, concomitantly with total regain of the glutathione status diminished by HFD, 42% to 59% recovery of lipid peroxidation and protein oxidation enhanced by HFD, and regain of Nrf2 functioning, whereas (iii) combined EPA + HT supplementation elicited 74% reduction in liver steatosis, with total recovery of the antioxidant potential in a similar manner than HT. It is concluded that combined HT + EPA drastically decreases NAFLD development, an effect that shows additivity in HT and EPA effects that mainly relies on HT, strengthening the impact of oxidative stress as a central mechanism underlying liver steatosis in obesity.
Most PE manoeuvres identify reasonably well subacromial impingement of the shoulder, although, in general, they have low specificity. The Yocum test has the best sensitivity and precision. Our data suggest that imaging techniques should be recommended to better define shoulder lesions.
Among the many causes of forefoot pain, Morton’s neuroma (MN) is often suspected, particularly in women, due to its high incidence. However, there remain controversies about its relationship with symptomatology and which diagnostic and treatment choices to choose. This article mainly focuses on the role of the various imaging methods and their abilities to support an accurate diagnosis of MN, ruling out other causes of forefoot pain, and as a way of providing targeted imaging-guided therapy for patients with MN.
• Ultrasound-guided steroid injections in Morton's neuroma provide short-term pain relief to over 60% of the patients. • Ultrasound-guided injections in Morton's neuroma lead to a higher percentage of short-term pain relief than blind injections. • Ultrasound-guided injections in Morton's neuroma lead to a lower percentage of skin side effects than blind injections.
Variceal and non-variceal upper gastrointestinal bleeding. Analysis of 249 hospitalized patients Background: Upper gastrointestinal bleeding (UGIB) is one of the main reasons of hospitalization due to gastrointestinal causes. Reported mortality rates range from 5 to 12%. Aim: To determine hospital mortality and associated risk factors in hospitalized patients with UGIB. To compare the clinical characteristics and outcomes of patients with variceal versus non-variceal UGIB. Material and Methods: Review of medical records of 249 patients (62% males) discharged with the diagnosis of UGIB at a clinical hospital between 2015 to 2017. Demographic and clinical characteristics and adverse clinical outcomes (surgery, length of hospital stay and in-hospital mortality) were recorded. A comparative analysis between patients with Variceal and Non-variceal UGIB was carried out. Results: Seventy two percent of UGIB were non-variceal (peptic ulcer in 44%). Two patients required surgery (both died). Median of length of hospital stay was seven days (interquartile range (IQR) 4-13). Overall hospital mortality was 13 and 4% in variceal and non-variceal UGIB, respectively (p = 0.024). The variables associated with mortality were: red blood cell transfusion (odds ratio (OR): 18.7, p < 0.01), elevated creatinine on admission (OR: 3.30, p = 0.03) and variceal bleeding (OR: 3.23, p = 0.02). Conclusions: Hospital mortality of UGIB remains high, especially in variceal UGIB. Elevated creatinine levels on admission, the need of transfusion of red blood cells and variceal etiology are risk factors for mortality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
