Colouration in amphibians as a reflection of nutritional status : the case of tree frogs in Costa Rica
Colouration has been considered a cue for mating success in many species; ornaments in males often are related to carotenoid mobilization towards feathers and/or skin and can signal general health and nutrition status. However, there are several factors that can also link with status, such as physiological blood parameters and body condition, but there is not substantial evidence which supports the existence of these relationships and interactions in anurans. This study evaluated how body score and blood values interact with colouration in free-range Agalychnis callidryas and Agalychnis annae males. We found significant associations between body condition and plasmatic proteins and haematocrit, as well as between body condition and colour values from the chromaticity diagram. We also demonstrated that there is a significant relation between the glucose and plasmatic protein values that were reflected in the ventral colours of the animals, and haematocrit inversely affected most of those colour values. Significant differences were found between species as well as between populations of A. callidryas, suggesting that despite colour variation, there are also biochemical differences within animals from the same species located in different regions. These data provide information on underlying factors for colouration of male tree frogs in nature, provide insights about the dynamics of several nutrients in the amphibian model and how this could affect the reproductive output of the animals
The prevalence of anxiety and depression in people with age-related macular degeneration: a systematic review of observational study data
Background Comorbid mental health problems have been shown to have an adverse effect on the quality of life of people with common eye disorders. This study aims to assess whether symptoms of anxiety and/or depression are more prevalent in people with age-related macular degeneration (AMD) than in people without this condition. Methods A systematic search of electronic databases (Medline, CINAHL, EMBASE, PsycINFO) from inception to February 2012 was conducted to identify studies of AMD populations which measured symptoms of anxiety and/or depression. Reference checking of relevant articles was also performed. Data on the study setting, prevalence and how anxiety and depression were measured were extracted from the papers. Critical appraisal was performed using the Critical Appraisal Skills Programme (CASP) tools. Results A total of 16 papers were included in the review, from an original search result of 597. The prevalence estimates, taken from nine cross-sectional and cohort studies, ranged from 15.7%-44% for depressive symptoms and 9.6%-30.1% for anxiety symptoms in people with AMD. The seven case–control studies found that people with AMD were more likely to experience symptoms of depression compared with those without AMD, but not more likely to experience symptoms of anxiety. Conclusions Overall, the evidence suggests that symptoms of depression are more prevalent amongst AMD populations than anxiety symptoms. The heterogeneity of the studies included in this review means that it is difficult to draw strong conclusions as to the true estimates of depression and anxiety symptoms in AMD populations and prevented formal meta-analysis. Further research which specifies clinical anxiety and gives clear definitions as to the type of AMD being investigated is required

Video assisted thoracoscopic resection of a posterior mediastinal Castleman's tumor
Abstract Castleman's disease (CD) or angiofollicular lymph node hyperplasia is a rare spectrum of lymphoproliferative disorders. CD tumors are commonly localized in the mediastinum and are usually asymptomatic. The mainstay of treatment is surgical resection and has typically been performed using open thoracotomy. Few reports in the literature describe video assisted thoracoscopic resection of these tumors. The differential diagnosis for mediastinal masses is extensive, and CD tumors, although uncommon, should be considered. We describe a case report of a posterior mediastinal Castleman's tumor adherent to the esophagus, which was resected thoracoscopically and review the literature.</p
Blind loop: rare but important surgical complication
BACKGROUND: Surgical complications worldwide are dreaded by both patients and physicians alike. They represent significant and serious morbidity and mortality, and contribute substantially to increased costs of healthcare. CASE PRESENTATION: Our Case Report describes a 65yo Caucasian man with an extensive operative history for Crohn’s disease, including 4 laparotomies with small bowel resections to ameliorate small bowel obstructions. He presented with signs and symptoms of a chronic draining sinus, but was found to have a Blind Loop of bowel. This finding is believed to be the result of a surgical complication. CONCLUSION: While the Case Reports discusses this particular patient presentation, the paper defines, describes and offers treatment strategies for Enterocutaneous Fistulas (ECF). We offer aim to add Blind Loop to the differential diagnosis when presented with a patient with signs and symptoms of ECF
