PURPOSE OF REVIEW: In modern society, cocoa is being eaten as a confectionery, contrary to its medicinal use in the past. However, since the last decade, there has been a revival of talks about cocoa's health beneficial effects. Development has been made at the molecular level recently. This review discusses the recent progresses on potential health benefits of cocoa and/or its derivatives, with a focus on the areas that have been paid little attention so far, such as the role of cocoa in immune regulation, inflammation, neuroprotection, oxidative stress, obesity, and diabetes control. RECENT FINDINGS: Thanks to the advancement in analytical technologies, the cocoa's metabolic pathways have now been properly mapped providing essential information on its roles. Cocoa helps in weight loss by improving mitochondrial biogenesis. It increases muscle glucose uptake by inserting glucose transporter 4 in skeletal muscles membrane. Because of its antioxidant properties, cocoa offers neuron protection and enhances cognition and positive mood. It lowers immunoglobulin E release in allergic responses. It can affect the immune response and bacterial growth at intestinal levels. It reduces inflammation by inhibiting nuclear factor-κB. SUMMARY: Keeping in view the pleiotropic health benefits of cocoa, it may have the potential to be used for the prevention/treatment of allergies, cancers, oxidative injuries, inflammatory conditions, anxiety, hyperglycemia, and insulin resistance. © 2013 Wolters Kluwer Health / Lippincott Williams & Wilkins.

Background: Hypoxaemia and high peak airway pressure (Ppeak) are common anesthetic problems during laparoscopic bariatric surgery. Several publications have reported the successful improvement in arterial oxygenation using positive end expiratory pressure and alveolar recruitment maneuver, however, high peak airway pressure during laparoscopic bariatric surgery may limit the use of both techniques. This study was designed to determine whether equal I:E (inspiratory-to-expiratory) ratio ventilation (1:1) improves arterial oxygenation with parallel decrease in the Ppeak values. Methods: Thirty patients with a body mass index ≥40 kg/m 2 scheduled for laparoscopic bariatric surgery were randomized, after creation of pneumoperitoneum, to receive I:E ratio either 1:1 (group 1, 15 patients) or 1:2 (group 2, 15 patients). After a stabilization period of 30 min, patients were crossed over to the other studied I:E ratio. Ppeak, mean airway pressure (Pmean), dynamic compliance (Cdyn), arterial blood gases and hemodynamic data were collected at the end of each stabilization period. Results: Ventilation with I: E ratio of 1:1 significantly increased partial pressure of O 2 in the arterial blood (PaO 2 ), Pmean and Cdyn with concomitant significant decrease in Ppeak compared to ventilation with I: E ratio of 1:2. There were no statistical differences between the two groups regarding the mean arterial pressure, heart rate, respiratory rate, end tidal CO 2 or partial pressure of CO 2 in the arterial blood. Conclusion: Equal ratio ventilation (1:1) is an effective technique in increase PaO 2 during laparoscopic bariatric surgery. It increases Pmean and Cdyn while decreasing Ppeak without adverse respiratory or hemodynamic effects. Source

Chocolate/cocoa has been known for its good taste and proposed health effects for centuries. Earlier, chocolate used to be criticised for its fat content and its consumption was a sin rather than a remedy, associated with acne, caries, obesity, high blood pressure, coronary artery disease and diabetes. Therefore, many physicians tended to warn patients about the potential health hazards of consuming large amounts of chocolate. However, the recent discovery of biologically active phenolic compounds in cocoa has changed this perception and stimulated research on its effects in ageing, oxidative stress, blood pressure regulation, and atherosclerosis. Today, chocolate is lauded for its tremendous antioxidant potential. However, in many studies, contradictory results and concerns about methodological issues have made it hard for health professionals and the public to understand the available evidence on chocolate's effects on health. The purpose of this review is to interpret research done in the last decade on the benefits and risks of chocolate consumption. © Van Zuiden Communications B.V. All rights reserved. Source

A new semi-empirical relation was presented to correlate the measured ultrasonic attenuation coefficient at room temperature with the packing density, dissociation energy per unit volume and first-order stretching force constant of the glass. A comprehensive study was carried out to examine the validity of this relation as well as Makishima and Mackenzie theory for TiO 2-doped 30CaO-30Al 2O 3-40B 2O 3 and x 1 Ag 2O-x 2 V 2O 5-(1-x 1-x 2) TeO 2 glass systems. It has been found that the correlation between ultrasonic attenuation coefficient and both packing density and dissociation energy per unit volume was achieved through first-order stretching force constant of the glass. Also, the theoretically calculated values of bulk modulus are in a good agreement with the corresponding experimentally measured values. Moreover, fractal bond connectivity and number of network bonds per unit volume play an important role in determining the changes in the structural and acoustical properties of the investigated glasses. © 2012 Elsevier B.V.

Background: Insertion of the peritoneal dialysis (PD) catheter by a nephrologist has been encouraged by several studies. The ultimate goal is to provide safe, timely, and effective catheter insertion without an unduly long wait time or delay. The success of PD depends partly on the ease of catheter insertion. We developed a new technique for percutaneous PD catheter insertion by nephrologists. Our new technique, in addition to being easy, proved to be safe and to eliminate the need for the peel-away sheath. Methods: Data were collected prospectively on all patients having a PD catheter inserted by a nephrologist using our new technique (40 catheters in 38 patients). All catheters were evaluated for infectious and mechanical complications. Results: The mean duration of the procedure from skin sterilization to the end of insertion was 24 ± 3 minutes. No bowel perforation or serious hemorrhage was recorded. Poor initial drainage was recorded in 12.5% of the catheters (n = 5) during the 4 weeks after insertion. The incidence of early exit-site leakage was 2.5% (1 catheter). Episodes of exit-site infection occurred in 5.0% and 12.5% of catheters (within 1 month and by the end of study period respectively). Two episodes of peritonitis were reported by the end of the 12-month period. Catheter survival was 95.0% and 87.5% at 6 months and 12 months respectively. Conclusions: Percutaneous bedside placement of PD catheters using our new technique is safe and carries less morbidity in terms of bowel perforation, catheter-related infection, and exit-site leak. In addition, our new technique appears to have a high success rate and to offer considerable savings in terms of operating time. © 2014 International Society for Peritoneal Dialysis. Source
