REVIEW
Wei Li, Denis Richard
Bariatric surgery represents the most efficient therapy for severe obesity. It reduces the size of fat stores or the amount of body fat gain. The bariatric surgery procedures currently used include Roux-en-Y gastric bypass and sleeve gastrectomy, which are the most commonly performed procedures. Other procedures are laparoscopic adjustable gastric banding and biliopancreatic diversion. The latter represents the most effective surgery for treatment of severe obesity as well as type 2 diabetes. Bariatric surgery reduces energy intake by restricting the size of the stomach reservoir and causing malabsorption, as in the case of biliopancreatic diversion...

REVIEW
Anobel Y Odisho, John L Gore
As care delivery shifts to further include patients in shared decision-making, patient-centered health information can balance the information asymmetry between patients and providers. Patient health literacy, numeracy, and graph literacy must match that of health information materials to create understandable health information that empowers patients to participate in shared decision-making. We consider an iterative approach focused on three key steps: assessment of the specific information needs of the selected patient community, assessment of that community's ability to receive and understand health information, and evaluation of the materials developed to assess effectiveness...

BACKGROUND: Venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis, is a serious complication after total joint arthroplasty (TJA). Risk assessment models are increasingly used to provide patient-specific risk stratification. A recently implemented protocol mandates calculation of a Caprini Score for all surgical patients at our institution. We investigated the accuracy of the Caprini Score in predicting VTE events following TJA. METHODS: A retrospective review of patients undergoing primary total hip (THA) and total knee arthroplasty (TKA) over a 1-year time period was performed...

The hematopoietic cell transplant (HCT) activity has grown significantly over the past two decades in both developing and developed countries. Many challenges arise in establishing new HCT programs in developing countries, due to scarcity of resources and manpower in expertise in HCT. While cost issues can potentially hinder establishment of new HCT programs in certain regions, the focus on quality and value should be included in the general vision of leadership before establishing an HCT program. The main challenge in most developing countries is the lack of trained/qualified personnel, enormous start-up costs for a tertiary care center, and quality maintenance...

Increased concentrations of kynurenic acid (KYNA) in the prefrontal cortex (PFC) are thought to contribute to the development of cognitive deficits observed in schizophrenia. Although this view is consistent with pre-clinical studies showing a negative impact of prefrontal KYNA elevation on executive function, the mechanism underlying such a disruption remains unclear. Here we measured changes in local field potential responses to ventral hippocampal stimulation in vivo, and conducted whole-cell patch-clamp recordings in brain slices to reveal how nanomolar concentrations of KYNA alter synaptic transmission in the PFC of male adult rats...

Atoh1 is a basic helix-loop-helix (bHLH) transcription factor that is essential for the genesis, survival, and maturation of a variety of neuronal and non-neuronal cell populations, including those involved in proprioception, interoception, balance, respiration, and hearing. Such diverse functions require fine regulation at the transcriptional and protein levels. Here we show that serine 193 (S193) is phosphorylated in Atoh1's bHLH domain in vivo Knock-in mice of both sexes bearing a GFP-tagged phospho-dead S193A allele on a null background (Atoh1(S193A/lacZ) ) exhibit mild cerebellar foliation defects, motor impairments, and also partial pontine nucleus migration defects, cochlear hair cell degeneration, and profound hearing loss...

The objective of this study was to evaluate the ability of a long-term antioxidant-supplemented diet to regulate the oxidative stress and general health status of dogs involved in animal-assisted intervention (AAI) programs. Oxidative stress is a consequence of the accumulation of reactive oxygen species (ROS). Exercise-induced oxidative stress can increase muscle fatigue and fiber damage and eventually leads to impairment of the immune system. A randomized, placebo-controlled, crossover clinical evaluation was conducted with 11 healthy therapy dogs: 6 females and 5 males of different breeds and with a mean age of 2...

Holstein-Friesian steer beef production is renowned globally as a secondary product of the milk industry. Grass feeding is a common practice in raising Holstein steers because of its low cost. Furthermore, grass feeding is an alternative way to produce beef with a balanced n-6 to n-3 fatty acids (FAs) ratio. However, the performance and meat quality of Holstein-Friesian cattle is more likely to depend on a high-quality diet. The aim of this study was to observe whether feeding two mixed diets; a corn-based total mixed ration (TMR) with winter ryegrass (Lolium perenne) or flaxseed oil-supplemented pellets with reed canary grass haylage (n-3 mix) provided benefits on carcass weight, meat quality and FA composition compared with cattle fed with reed canary grass (Phalaris arundinacea) haylage alone...

Near-equilibrium calcite dissolution in seawater contributes significantly to the regulation of atmospheric [Formula: see text] on 1,000-y timescales. Despite many studies on far-from-equilibrium dissolution, little is known about the detailed mechanisms responsible for calcite dissolution in seawater. In this paper, we dissolve (13)C-labeled calcites in natural seawater. We show that the time-evolving enrichment of [Formula: see text] in solution is a direct measure of both dissolution and precipitation reactions across a large range of saturation states...

The adjustment of the balance between strength and ductility is still a great challenge for ultrahigh temperature materials. Essentially, the strength depends on the valence electron density of transition metals and the bond strength of chemical bonding. However, the ductility of a solid is mainly determined by the symmetrical slips and crystal structure. Based on the above design principles, we apply first-principles calculations to investigate the structure, elastic properties and brittle-or-ductile behavior of TM3Sis with a cubic structure...
