Anorectal strictures are a notoriously difficult to treat phenotype of perianal Crohn's disease. Quality of life is diminished due to ongoing pain, incontinence, difficulty with stool evacuation, and recurrent medical and surgical treatments. Medical therapy is aimed at treating luminal disease and mucosal ulceration to prevent worsening of fibrosis. Clinical examination and endoscopic intervention can be used for serial dilations of strictures. Unfortunately, despite optimal medical therapy and endoscopic intervention with serial anal dilations, surgery with intestinal diversion or proctocolectomy may be required as part of the treatment algorithm in a significant proportion of patients.Despite significant improvements in the management of ulcerative colitis (UC) in parallel with the evolution of therapeutic targets and novel biologics and small molecules, a subset of medically refractory patients still requires colectomy. Recent population-based studies demonstrate a trend toward a decrease in the rates of surgery for UC patients in the biological era, although the potential of disease modification with these agents is still debated. As the concept of irreversible bowel damage is underexplored in UC, refractory patients can be exposed to multiple treatments losing optimal timing for surgery and further developing complications such as dysplasia/cancer, dysmotility, microcolon, and other functional abnormalities. This review aims to discuss the concept of disease progression in UC, explore the limitations of medical treatment in refractory UC patients, and propose the application of a three-step algorithm that allows timely indication for surgery in clinical practice.Perianal fistulizing Crohn's disease (PFCD) represents a challenging and complex disease phenotype. Patients typically suffer a more severe disease course than those without perianal complications and are often managing debilitating symptoms. Etiology is understood to be multifactorial, with genetic predisposition, microbiological insult, aberrant immunity, and mechanical factors all implicated. As a result, multimodal treatment strategies must be employed to achieve disease control and fistula closure. This requires the complimentary involvement of medical and surgical disciplines in order to ensure thorough assessment and treatment tailored to the individual scenario and patient goals. The aim of this article is to describe an overview of the various treatment strategies available for PFCD, focusing on how a synergistic approach is required to ensure maximal chances of success.Rectovaginal fistula (RVF) occurring during the course of Crohn's disease (CD) constitutes a therapeutic challenge and is characterized by a high rate of recurrence. To optimize the outcome of CD-related RVF repair, the best conditions for correct healing should be obtained. Remission of CD should be achieved with no active proctitis, the perianal CD activity should be minimized, and local septic complications should be controlled. The objective of surgical repair is to close the fistula tract with minimal recurrence and functional disturbance. Several therapeutic strategies exist and the approach should be tailored to the anatomy of the RVF and the quality of the local supporting tissues. Herein, we review the medical and surgical management of CD-related RVF.Complex perianal Crohn's disease (CD) remains a challenging problem. Fecal stream is thought to be a trigger of disease progression in patients with CD. In patients with refractory perianal CD, diversion of fecal stream is sometimes required to alleviate clinical symptoms when medical and local surgical management are unsuccessful. Several studies evaluated the outcomes of fecal diversion for complex perianal CD. After fecal diversion, the majority of patients achieved early clinical response, but the prospect of restoring bowel continuity was low (approximately 20%). Immunology inhibitor Nearly half of the patients eventually required proctectomy. A number of studies attempted to identify predictive factors for the outcomes of fecal diversion. Only rectal involvement was associated with unsuccessful restoration of bowel continuity. Biologic therapy did not seem to improve the efficacy of fecal diversion, although the evidence level was low because of insufficient data or methodological limitations. Based on these results, fecal diversion may be useful in alleviating clinical symptoms related to severe perianal CD and avoiding immediate proctectomy. The impact of biologic therapy on the outcomes of fecal diversion should be further investigated.Combined rectal prolapse and pelvic organ prolapse surgery provides significant quality-of-life benefits with improvements in bothersome symptoms of pain, bulge, constipation, urinary retention, as well as bowel and bladder incontinence. Robotic surgery is the ideal tool for a combined surgical repair. It allows enhanced suturing in the deep pelvis, three-dimensional (3D) visualization of the presacral space and easy mobilization of the rectum and dissection of the vagina. Combined procedures can be offered to patients with the advantages of a single operation and concurrent recovery period without increasing complications. In this article, we highlight our approach to combined prolapse repair.Subtotal colectomy (STC) or total proctocolectomy (TPC) and ileal pouch-anal anastomosis (IPAA) performed in two or three stages remain the procedure of choice for patients with ulcerative colitis (UC). Minimally invasive laparoscopic approaches for STC and IPAA have been established for over a decade, having been shown to reduce postoperative pain, length of stay, and improve fertility. However "straight-stick" laparoscopy has ergonomic and visual disadvantages in the pelvis, which may contribute to IPAA failure. The robotic platform was developed to overcome these limitations. Robotic STC is associated with lower conversion rates and earlier return of bowel function with acceptably longer operative time (mean, 28 minutes) than laparoscopic STC. The robotic approach has also been shown in case series to be safe in urgent settings. Robotic IPAA is associated with lower blood loss and length of stay than laparoscopic IPAA. Robotic TPC/IPAA has been shown in small case series to be safe and feasible despite longer operating times.A computational study rationalizes the different phosphorescence colors of two highly emitting crystal polymorphs of a dinuclear Re(I) complex, [Re2(μ-Cl)2(CO)6(μ-4,5-(Me3Si)2pyridazine)]. The electrostatic interactions between the charge distributions on neighboring molecules inside the crystal are responsible for the different stabilization of the emitting triplet state because of the different molecular packing. These self-consistent effects play a major role in the phosphorescence of crystals made of polar and polarizable molecular units, offering a powerful handle to tune the luminescence wavelength in the solid state through supramolecular engineering.

To explore the relationship between SES and language domain (vocabulary, syntax, process), the QUILS was administered to 212 kindergartners.

Children from very-high poverty schools performed significantly below children from high poverty and mid-low poverty schools.

SES impacts language-learning processes (i.e., fast mapping) in addition to language products (i.e., vocabulary, syntax).

Preoperative anemia is independently associated with worse postoperative outcomes following cardiac and noncardiac surgery. This article explores the current understanding of perioperative anemia and iron deficiency with reference to definition, diagnosis, and treatment.

Iron deficiency is the most common cause of anemia. It can arise from reduced iron intake, poor absorption, or excess iron loss. Inflammation throughout the preoperative period can drive iron sequestration, leading to a functional deficiency of iron and the development of what was referred to until recently as the "anemia of chronic disease." Current best practice guidance supports the routine administration of preoperative intravenous iron to treat anemia despite limited evidence. This "one size fits all" approach has been called into question following results from a recent large, randomized trial (the PREVENTT trial) that assessed the use of a single dose of intravenous iron compared to placebo 10-42days before major abdominal surgery. and between postoperative anemia, delayed outcomes (hospital readmission), and the efficacy of postoperative intravenous iron is required.

Despite the known associations between preoperative anemia (particularly iron deficiency anemia) and poor postoperative outcome, recent evidence suggests that administering intravenous iron relatively close to surgery does not yield a tangible short-term benefit. This is made more complex by the interplay between iron and innate immunity. Iron deficiency irrespective of hemoglobin concentration may also impact postoperative outcomes. Therefore, further research into associations between iron deficiency and postoperative outcomes, and between postoperative anemia, delayed outcomes (hospital readmission), and the efficacy of postoperative intravenous iron is required.

This review illustrates the current benefits, limitations, ongoing research, and future paths for Low Titer O Whole Blood compared to Component Therapy in massive transfusion for trauma patients.

Many studies show that compared to Component Therapy, Low Titer O Whole Blood transfusion is associated with better patient outcomes and simplified transfusion logistics among others. There are, however, issues with cost, supply/demand and handling of Whole Blood that limit its use, but experience in the military setting has shown that these limitations can be easily overcome.

The use of Whole Blood has increased in the civilian trauma population and there is a growing body of evidence to support its current use. More research looking at Whole Blood in females of child-bearing age, pediatric populations, and cold-stored platelets is underway.

Using the Spanish Labour Force Survey and conducting a socio-occupational analysis, we predict the probability that a migrant would be employed in one socio-occupational class over another in three periods before, during and after the crisis. Our main research questions are as follows (1) To what extent do migrants tend to be located in certain socio-occupational classes? (2) To what extent does the likelihood of belonging to a certain socio-occupational class differ according to immigrants' places of origin? (3) Can differences be found in the likelihood of belonging to a certain socio-occupational class according to the places of origin before, during and after the Great Recession? The results show a very unequal distribution of immigrants in the socio-occupational structure according to their origin. While immigrants from Schengen Europe and North America are better located in the occupational structure, those from Eastern Europe and Africa are over-represented in the lower socio-occupational classes.
