Background & AimsAnti–tumor necrosis factor (anti-TNF) therapies are the most widely used biologic drugs for treating immune-mediated diseases, but repeated administration can induce formation of anti-drug antibodies. The ability to identify patients at increased risk development antibodies would facilitate selection therapy and use preventative strategies.MethodsWe performed a genome-wide association study variants associated with time in discovery cohort 1240 biologic-naïve Crohn's disease...

SUMMARY An efficient method is presented for obtaining, in under 4h, an unbiased estimate of the total number neurons human neocortex, with a coefficient error on ∼ 5%. The novel sampling scheme used this study and was designed so that only small amount neocortical grey matter had to be removed. Hence, majority cerebral all internal left intact further resampling analysis. Each hemisphere subdivided into four major regions, sliced coronally at 7‐mm intervals volume neocortex determined using...

Ultrafine and fine particles are potent adjuvants in antigen-mediated immune responses, cause inflammation susceptible individuals. Following recent findings that microparticles accumulate the phagocytes of intestinal lymphoid aggregates, this study is first investigation whether their reduction diet improves symptoms Crohn's disease.In a double blind study, 20 patients with active corticosteroid-treated ileal or ileo-colonic disease randomly received either low microparticle (trial group; n...

Abstract Background Specific image defined risk factors (IDRF) immediately prior to surgery may be more relevant paediatric oncology surgeons than pre‐neoadjuvant IDRFs at diagnosis. The aim of this study was determine IDRF subtypes that independently predict postoperative complications. Methods We searched the New Zealand Children's Cancer Registry for all cases neuroblastoma treated a single centre between January 2007 and February 2021 determined status on pre‐operative imaging diagnosis...

Previously, abobotulinumtoxinA (aboBoNT-A) injected intraoperatively resulted in effective, but delayed post-surgical analgesia pigs. Here, we explore the efficacy of preemptively administered aboBoNT-A intact animals on pain and associated behaviors following a full-skin-muscle incision retraction surgery lower back. AboBoNT-A (200 U/animal) or saline, distributed across ten points, were around anticipated 15, 5, 1 day before via ID route (part A) 15 days ID, intramuscular (IM) subcutaneous...

<b>Introduction</b> Postoperative antibiotics complement surgery in managing childhood-complicated appendicitis. However, there is limited evidence to guide clinicians on appropriate duration of therapy. A comparison cohort study was performed determine whether tailoring inpatient intravenous (IV) antibiotic therapy patient response, assessed using a set clinical criteria, leads shortened hospital length stay (LOS) without compromising outcomes. <b>Patients and Methods</b> Over 6-month...

Abstract Background It has been consistently observed that a significant proportion of hospital inpatients are malnourished and many actually develop malnutrition in hospital. The NHS provides over 300 million meals each year at cost £500 million, yet there is relatively little research evaluating how well different catering systems provide for the needs inpatients. Aim aim study was to: (i) evaluate whether new steam meal system (Steamplicity) enables patients theory to meet their energy...
