Sarcopenia is the loss of muscle mass and function related to aging, undereating, disease conditions, or inactivity. Pre-existing sarcopenia diminishes the functional reserve of patients with cancer which increases their risk for frailty, cancer cachexia, and worse outcomes from treatments. The pathogenesis of sarcopenia is multi-factorial opening opportunities for clinicians to work across disciplines to improve patient outcomes and quality of life. The purpose of this essay is to describe sarcopenia, discuss clinical screening and assessment for sarcopenia, and highlight potential interventions to manage sarcopenia in the urologic oncology population.One problem areas of animal models and tests for neuropsychiatric disorders is unclear reproducibility, including both internal and external validity. One way to examine external validity is with systematic reviews and meta-analyses, a standard practice in clinical research that is relatively neglected in preclinical research. Considering the need to evaluate the validity and reproducibility of frequently used animal models, this study presents a meta-analysis of the effects of prototypic benzodiazepines and specific serotonin reuptake inhibitors (SSRIs) in the mouse defensive marble burying test (MBT). These drug groups were selected because although they differ in their biological targets as well as in their clinical use, they are both commonly used for the treatment of anxiety disorders. A PubMed literature search was performed to identify studies that examined the effects of benzodiazepines (diazepam, alprazolam, chlordiazepoxide, clonazepam) or SSRIs (fluoxetine, citalopram, escitalopram, fluvoxamine, paroxetine) in the MBT in mice. For benzodiazepines, 73 experiments were included. Benzodiazepines effect size was 2.04 and Q statistics was 1959 with a significant correlation between dose and effect size (r = 0.31, p = 0.007). For SSRIs we identified 47 experiments. Effect size of SSRIs was 2.24 and Q statistics was 493.38. No correlation was found between dose and effect size (r = 0.23, p = 0.12). The current results support the external validity of the defensive marble burying test as a screening test for anxiolytic effects. However, these results indicate that significant attention should be given to the administration schedules of benzodiazepines and SSRIs.It has been reported that decision making is impaired in suicide attempters. Decision making is a complex process and little is known about its different components. Yet, this information would help to understand the functioning of suicidal minds. In this study, the Prospect Valence-Learning (PVL) computational model was applied to the Iowa Gambling Task (IGT) to investigate and compare decision-making components in patients with affective disorder and with/without history of suicide attempts and in healthy controls. To this aim, 116 inpatients with current major depressive episode (among whom 62 suicide attempters) and 38 healthy controls were recruited. Decision-making performance was measured using the IGT. The Bayesian computational PVL model was applied to compare the feedback sensitivity, loss aversion, learning/memory, and choice consistency components of decision making in the different groups. Depressive symptomatology was assessed using the Beck Depression Inventory short form (BDI-SF). The total IGT net score and the loss aversion and learning/memory scores were lower in suicide attempters than in healthy controls. The choice consistency score was low in all patients (with/without suicide history) compared with healthy controls. Moreover, patients with high BDI score showed a positive relationship between the choice consistency score and suicide attempt. These findings suggest that decision-making impairment in depressed patients with and without suicidal history might be the result of underlying problems in feedback processing and task learning, which influence the building of long-term strategies. All these impairments should be targeted in therapeutic strategies for suicidal patients.Background Obesity is well known to increase the risk of gastroesophageal reflux disease (GERD). The impact of sleeve gastrectomy (SG) on GERD is still discussed but seems to be associated with the development of de novo GERD or the exacerbation of preexisting GERD. Objective The objective of this study was to evaluate the impact of preoperative pH monitoring, using the DeMeester score (DMS), on the risk of conversion to Roux-en-Y gastric bypass (RYGB) after SG. Setting University Hospital in Nantes, France. Methods This monocentric study reported the results of a retrospective chart review of 523 obese individuals treated between 2011 and 2018. All patients underwent primary bariatric surgery; 95% had undergone an SG. GERD diagnosis was established with preoperative DMS based on 24-hour esophageal pH monitoring. Results Preoperative DMS was identified in 423 patients (86%). Sixty-seven patients (14%) underwent a second bariatric procedure; among them, 36 (54%) have been converted to RYGB because of GERD. There was no significant difference between preoperative DMS (16.1 ± 22 versus 13.7 ± 14, P = .37) in patients undergoing conversion for GERD and the nonconverted ones. PR-619 ic50 The sensitivity, specificity, positive predictive, and negative predictive values of the preoperative DMS for predicting conversion to RYGB were 25%, 66%, 7%, and 4%, respectively. In patients who underwent a conversion for GERD, DMS (P less then .002), rates of esophagitis (P = .035), and hiatal hernia (P = .039) significantly increased after SG. Conclusion Preoperative DMS alone is not predictive of the risk of conversion of SG to RYGB for GERD.Centrioles organize the microtubule network and mitotic spindle and, as basal bodies, nucleate cilia and flagella. They undergo a beguiling process in which one appears to give rise to another and at a baffling orthogonal geometry. Nucleic acid-based replication has been pondered during cycles of zeniths and nadirs of plausibility, the latter now the state. Centrioles can also arise de novo, and thus the longstanding focus on centriole 'replication' may have led us astray from ground truth. We are in an era in which the assembly pathways of most intracellular machines are becoming understood in considerable detail. But apart from knowing the structure and parts list, little in our extant knowledge conveys how centrioles arise. Here the matters at hand are summarized, and a siren call is sounded.Background The novel coronavirus SARS-CoV-2 has taken the world by storm. Alongside COVID-19, diabetes is a long-standing global epidemic. The diabetes population has been reported to suffer adverse outcomes if infected by COVID-19. The aim was to summarise information and resources available on diabetes and COVID-19, highlighting special measures that individuals with diabetes need to follow. Methods A search using keywords "COVID-19" and "Diabetes" was performed using different sources, including PubMed and World Health Organization. Results COVID-19 may enhance complications in individuals with diabetes through an imbalance in angiotension-converting enzyme 2 (ACE2) activation pathways leading to an inflammatory response. ACE2 imbalance in the pancreas causes acute β-cell dysfunction and a resultant hyperglycemic state. These individuals may be prone to worsened COVID-19 complications including vasculopathy, coagulopathy as well as psychological stress. Apart from general preventive measures, remaining hydrated, monitoring blood glucose regularly and monitoring ketone bodies in urine if on insulin is essential. All this while concurrently maintaining physical activity and a healthy diet. Different supporting entities are being set up to help this population. Conclusion COVID-19 is a top priority. It is important to remember that a substantial proportion of the world's population is affected by other co-morbidities such as diabetes. These require special attention during this pandemic to avoid adding on to the burden of countries' healthcare systems.Gut microbiota shape the metabolome which then directly impacts host physiology. Sinha et al. observe and suggest that decreases in the levels of Ruminococcaceae and secondary bile acids (SBAs) contribute to pouchitis in ulcerative colitis (UC) patients with ileal pouch anal anastomosis (IPAA), raising the possibility of using SBAs as a preventative measure.Mexico is a country that makes heavy use of the shark populations that inhabit the southern portion of the Northeast Pacific Ocean (NEP). Shark meat has become an essential food source in this country, while shark fins are used to supply traditional Asian markets. In addition to consumptive utilization, charismatic shark species support an ecotourism industry that has gained significance in several tourist resorts across the country. In this concluding chapter, we recap the contents of chapters included in volumes 83 and 85 in the Advances in Marine Biology series. The chapters in these volumes address biodiversity, conservation genetics, trophic ecology, migratory movements, fisheries, and shark ecotourism, allowing us to understand the state of knowledge relevant to human shark interactions in the Mexican Pacific. We discuss the challenges for the sustainable use and conservation of sharks in the southern NEP and highlight the need for a more holistic management approach that includes economic and social factors. To meet these challenges, we recommend updating the Mexican National Plan of Action for Sharks published in, 2004, such that it may continue serving as a roadmap for the conservation and management of sharks in the southern NEP during the years to come.Shark ecotourism has the potential to contribute significantly to local and national economies and conservation, though this depends on a concerted effort to implement evidence-based management. Sharks are key attractions at some of the most important marine ecotourism sites throughout Mexico, focusing particularly on whale sharks, white sharks, hammerhead sharks, and several other reef-associated and pelagic species. This generates important employment opportunities and millions of USD in revenue, but truly implementing ecotourism requires that education and conservation be a part of activities and that these benefit local communities, so that the industry can be socially, economically and ecologically sustainable. In Mexico, this includes addressing potential negative impacts from vessel overcrowding, provisioning, inequitable distribution of ecotourism and conservation benefits and costs, and a broader lack of governance capacity to ensure that coastal development is environmentally sustainable and socially equitable. In the context of a Blue Economy centred on sustainability and local benefits, ecotourism provides a key incentive and opportunity to improve ocean management.Sharks have been of great cultural and socioeconomic importance in Mexico since the late 19th century, when the first fisheries were prosecuted in the Gulf of California to export fins to China. Mexican shark and ray fisheries are classified mainly by the size of the fishing vessel and include small- (7.5-10m), medium- (10-27m), and large-sized (>27m) fisheries. All are multispecies fisheries that use longline or gillnet gear, with their relative productivity varying over time. Off the Pacific coast, early shark small size vessel fisheries in the Gulf of California were driven by the need for vitamin A from livers, especially during World War II. As this fishery declined, new shark fishing opportunities arose because of government support and the development of the medium-sized fishery, which was capable of farther offshore excursions. Shark meat became an important part of the diets of poor and impoverished citizens during the 1950s and 1960s. The establishment of a Mexican Exclusive Economic Zone in 1976 pushed foreign vessels from Asia out of Mexican waters and led to the development of the large-sized vessel fishery to exploit pelagic sharks in offshore waters.
