RESUMEN
Currently, it has been stated that psychiatric and psychological problems are equally paramount aspects of the clinical modulation and manifestation of both the central nervous and digestive systems, which could be used to restore balance. The present narrative review aims to provide an elaborate description of the bio-psycho-social facets of refractory functional gastrointestinal disorders, psychiatrists' role, specific psychiatric approach, and the latest psychiatric and psychological perspectives on practical therapeutic management. In this respect, "psyche," "psychiatry," "psychology," "psychiatrist," "psychotropic," and "refractory functional gastrointestinal disorders" (as the keywords) were searched in relevant English publications from January 1, 1950, to March 1, 2024, in the PubMed, Web of Science, Scopus, EMBASE, Cochrane Library, and Google Scholar databases. Eventually, the narrative technique was adopted to reach a compelling story with a high level of cohesion through material synthesis. The current literature recognizes the brain-gut axis modulation as a therapeutic target for refractory functional gastrointestinal disorders and the bio-psycho-social model as an integrated framework to explain disease pathogenesis. The results also reveal some evidence to affirm the benefits of psychotropic medications and psychological therapies in refractory functional gastrointestinal disorders, even when psychiatric symptoms were absent. It seems that psychiatrists are required to pay higher levels of attention to both the assessment and treatment of patients with refractory functional gastrointestinal disorders, accompanied by educating and training practitioners who take care of these patients.
RESUMEN
BACKGROUND: A previously published conditional probability model optimizes prehospital emergency transport protocols for patients with suspected large-vessel occlusion by recommending the transport strategy, drip-and-ship or mothership, that results in a higher probability of an excellent outcome. In this study, we create generalized models to quantify the change in annual hospital patient volume, the expected annual increase in the number of patients with an excellent outcome, and the annual cost savings to a single-payer healthcare system resulting from these optimized transport protocols. METHODS: We calculated the expected number of patients with suspected large-vessel occlusion transported by ambulance over a 1-year period in a region of interest, using the annual stroke incidence rate and a large-vessel occlusion screening tool. Assuming transport to the closest hospital is the baseline transport policy across the region (drip-and-ship), we determined the change in annual hospital patient volume from implementing optimized transport protocols. We also calculated the resulting annual increase in the number of patients with an excellent outcome (modified Rankin Score of 0-1 at 90 days) and associated cost savings to a single-payer healthcare system. We then performed a case study applying these generalized models to the stroke system serving the Greater Vancouver and Fraser Valley Area, BC, Canada. RESULTS: In the Greater Vancouver and Fraser Valley Area, there was an annual increase of 36 patients with an excellent outcome, translating to an annual cost savings of CA$2 182 824 to the British Columbia healthcare system. We also studied how these results change depending on our assumptions of treatment times at the regional stroke centers. CONCLUSIONS: Our framework quantifies the impact of optimized emergency stroke transport protocols on hospital volume, outcomes, and cost savings to a single-payer healthcare system. When applied to a specific region of interest, these models can help inform health policies concerning emergency transport of patients with suspected large-vessel occlusion.

BACKGROUND: Pneumatosis intestinalis is an abnormal presence of free air outside the lumen of the intestines in many shapes. It is classified based on its etiology to primary or secondary, it affects adults as well as infants and can involve any part of the GI tract. CASE PRESENTATION: We report a case of a 55-year-old man with a past medical history of a surgically repaired perforated duodenal ulcer who presented with an acute abdominal pain, Flatulence and constipation. On examination of the abdomen; severe distension, tenderness and tympanicity on percussion were noted. An erect CXR was performed and showed bilateral sub-diaphragmatic air levels. We performed an abdominal Paracentesis under the right subcostal margin which led to evacuation of large amounts of air. Next, an investigational laparotomy showed that the reason was a gastric volvulus associated with an anterior and posterior gastric wall lacerations. The suitable surgical repair approach was taken, but another lesion was detected incidentally. A pneumatosis cystoides intestinalis (PCI) was extended along large length of the intestines in many shapes and without any symptoms or signs. CONCLUSIONS: Pneumatosis cystoides intestinalis has been reported continuously in relation to peptic ulcer disease (PUD). We aim to report a new association of a gastric volvulus and PCI secondary to pyloric stenosis caused by a duodenal ulcer; which we believe can aid in the diagnosing of dangerous complications, of a rare disease.

In recent decades, allergic diseases subsequent from an IgE-mediated response to specific allergens have become a progressively public chronic disease worldwide. They have shaped an important medical and socio-economic burden. A significant proportion of allergic disorders are branded via a form 2 immune response relating Th2 cells, type 2 natural lymphoid cells, mast cells and eosinophils. Interleukin-21 (IL-21) is a participant of the type-I cytokine family manufactured through numerous subsets of stimulated CD4+ T cells and uses controlling properties on a diversity of immune cells. Increasingly, experimental sign suggests a character for IL-21 in the pathogenesis of numerous allergic disorders. The purpose of this review is to discuss the biological properties of IL-21 and to summaries current developments in its role in the regulation of allergic disorders.

Objective: Surveying public awareness of antibiotic use and antibiotics can identify factors relevant to the design of effective educational campaigns. The aim of this study was to evaluate the knowledge, attitudes, and practices related to antibiotic use and multidrug-resistant pathogens in the general population in Pakistan. Research Design and Methods: Cross-sectional survey was conducted, using a 60 itemed structured questionnaire and recruited individuals by convenient sampling from the general population in the four provinces of the country. Descriptive statistics were used to evaluate the responses and the chi squared statistic was used to assess differences between groups. Results: The response rate was 87.6% (6,684 out of 7,631 individuals). Half of the respondents had received at least one prescription of antibiotics in the 6 months preceding the survey. Knowledge about antibiotic use, (39.8%) individuals scored above the mean (≥3) showed good knowledge about antibiotic use. Urban residents and male showed significant higher knowledge (p < 0.001) about antibiotic use. Approximately 50% of the respondents correctly answered the question about antibiotic resistance. Of the 3,611 received antibiotics, 855 (23.7%) were indicated for cough, 497 (13.8%) for a sore throat, 335 (9.3%) for ear ache, 665 (18.4%) for a burning sensation during urination, 667 (18.4%) for wounds or soft tissue inflammation. MDR pathogen was perceived as an important topic by (4,010) 60.1% of respondents. Conclusion: Participants were aware of the problem of multidrug-resistant pathogens and understood the responsibility of each individual to avoid the spread of these infectious agents.
RESUMEN
OBJECTIVE: To evaluate the health-related quality of life (HRQoL) for adolescents with type 1 diabetes mellitus (T1DM). METHODS: A cross-sectional study was conducted among 214 adolescents (13-18 years) with T1DM at the Diabetes Treatment Center, Prince Sultan Military Medical City, Riyadh, Saudi Arabia from June to September 2013. Respondents were selected by their availability during routine visits to outpatient clinics, and interviewed using the Arabic translated version of the Pediatric Quality of Life Inventory 3.0 Diabetes Module (PedsQL 3.0 DM) independently. RESULTS: Female gender, multiple daily injection (MDI), longer duration of T1DM (>7 years), diabetic ketoacidosis (DKA) and adolescents with >7 HbA1c level had at least one poor HRQoL outcome. Multivariate linear regression analysis showed that age, treatment type (MDI), DKA, and >7 HbA1c were independent influencing factors for subscale diabetes symptoms, whereas >7 HbA1c was the independent influencing factor for treatment barriers and overall HRQoL. The DKA was the independent influencing factor for the subscale of worry, and female gender was the independent influencing factor for the subscale of communication. CONCLUSION: Female gender, age, treatment type, >7 HbA1c, and DKA are the strongest determinants for lower HRQoL for at least one subscale of the PedsQL 3.0 DM.
