RESUMEN
More than 2 billion people worldwide lack access to safe drinking water. Household water treatment (HWT) is an interim option for reducing the risk of water born disease. Understanding the factors that influence HWT behaviour is crucial for delivering successful interventions aimed at scaling relevant technologies, but the literature tends to emphasise psychological determinants with little consideration of socioeconomic and contextual factors. This article responds to this literature by using the COM-B model to examine the determinants of HWT practices through a comprehensive and context-sensitive behaviour definition. We informed this model through a cross-sectional survey design in which we collected data from 913 households in two periurban neighbourhoods of Kabul, Afghanistan. Our findings from descriptive statistical and regression analysis highlight the importance of not only psychological but also socio-economic and contextual determinants of HWT behaviour: Especially the COM-B dimensions of reflective and automatic motivation, and physical opportunity - which are heavily influenced by local context and economic circumstances - had statistically significant associations with performing HWT. The practical significance of these dimensions was similarly pronounced. For example, an increase in the physical opportunity index by 0.1 units from an average value of 0.7 to 0.8 would be associated with a 7.7 percentage-point higher likelihood of HWT performance. These results suggest that the COM-B model can be utilised to systematically design interventions aimed at promoting HWT practices, while highlighting the need to broaden behavioural analyses of HWT and consider contextual factors to develop interventions that are tailored to the specific needs and obstacles of different communities.

Aim: This study aimed to investigate the frequency of unnecessary tests requested in Be'sat Hospital in Hamadan. Materials and Methods: This descriptive research was conducted in order to investigate the frequency of unnecessary requests for CT scan and radiography of patients referring to the imaging department of Be'sat Hospital in Hamadan in a 4- to 6-month period. Patient information, including gender, age, type of CT scan test, the reason for requesting the test, the expertise of the requesting physician, and the result of the radiologist's report on each test, was extracted and collected. Results: A total of 1000 CT scans were evaluated. The mean age of these patients was about 36 years and most of them were men. The highest and lowest percentages of unnecessary cases were related to CT scans of the brain (42.3%) and facial bones (2.3%), respectively. The most and the least unnecessary CT scans based on the reason given for the request were related to multiple physical trauma (30.7%) and chronic kidney disease (1.5%), respectively. Conclusion: In all tests, over 74% of the reports were unnecessary and less than 26% were necessary. Therefore, it is necessary to reduce unnecessary requests to reduce the radiation dose of patients. Also, the knowledge of doctors should be increased in the field of appropriate evaluation of CT scan tests based on clinical guidelines.
RESUMEN
INTRODUCTION: Emergent surgery for colorectal cancer (CRC) is associated with higher rates of morbidity and mortality and outcomes differ by surgical approach. METHODS: Our study compares short-term surgical outcomes of patients undergoing emergent colectomy for CRC using the open vs minimally invasive (MIS) approach. We performed a four-year review (2012-2015) of the ACS-NSQIP Colectomy dataset and included all adult patients with CRC who underwent emergent surgical intervention. Patients were stratified into groups based on surgical approach: Open and MIS (including laparoscopic and robotic). RESULTS: A total of 1855 (MIS: 279, Open: 1576) patients were included. Outcome measures were operative time, 30-day complications, 30-day readmission, and 30-day mortality. Multivariate Regression analysis was performed. Patients in the open group were more likely to be older (70y vs. 61y, p < 0.01), have higher ASA class, and were less likely to have received mechanical bowel preparation. On univariate analysis, patients in the MIS group had longer operative time (189 ± 41 min vs. 161 ± 69 min, p < 0.01). Patients in the open group had higher rates of mortality (6.7% vs. 3.8%, p < 0.01) and 30-day complications (28.1% vs. 16.7%, p < 0.01). On regression analysis, the open approach was independently associated with higher odds of 30-day mortality and 30-day complications. CONCLUSION: Given the lower overall mortality and complications, MIS colectomy may be a safer approach in the emergent treatment of patients with colorectal cancer.

Background: Road traffic crashes (RTCs) and its associated injuries are one of the most important public health problems in the world. In Iran, RTCs rank second in terms of mortality. To address this issue, there is a need for research-based interventions. Prioritizing researches using a variety of approaches and frameworks to determine the most effective interventions is a key nodal point in the RTCs' research policy planning cycle. Thus, this study aims to generate and prioritize research questions in the field of RTCs in Iran. Methods: By adapting the Child Health and Nutrition Research Initiative (CHNRI) method, this study engaged 25 prominent Iranian academic leaders having role in setting Iran's long-term road safety goals, a group of research funders, and policymakers. The experts' proposed research questions were independently scored on a set of criteria: feasibility, impact on health, impact on the economy, capacity building, and equity. Following the prioritization of Research Questions (RQs), they were all classified using the 5 Pillar frameworks. Results: In total, 145 Research Questions were systematically scored by experts against five criteria. Iran's top 20 road traffic safety priorities were established. The RQs related to "road safety management" and "road and infrastructure" achieved a high frequency. Conclusions: The top 20 research questions in the area of RTCs in Iran were determined by experts. The majority of these RQs were related to "road safety management". The results of this study may contribute to the optimal use of resources in achieving long-term goals in the prevention and control of road traffic crashes and its related injuries. Considering these RQs as research investment options will improve the current status of Road Traffic Injuries (RTIs) at a national level and further advance toward compliance with international goals. If these research priorities are addressed, and their findings are implemented, we can anticipate a significant reduction in the number of crashes, injuries, and deaths.

INTRODUCTION: Preoperative anemia is relatively common in colon cancer patients; however, its impact on short-term surgical outcomes is not well established. The aim of our study was to evaluate short-term surgical outcomes in colon cancer patients with preoperative anemia undergoing colectomy. METHODS: We performed a 4-year analysis of the ACS-NSQIP and included all adult patients who underwent colectomy for colon cancer. Patients were stratified into two groups based on preoperative anemia (Preop Anemia, No Preop Anemia). Our outcome measures were 30-day complications, 30-day unplanned readmissions, and 30-day mortality. RESULTS: A total of 35,243 colon cancer patients who underwent colectomy were included in the analysis, of whom 50.4% had preoperative anemia. The mean age was 65 ± 13 years and the mean hemoglobin level was 12 ± 2 g/dL. Patients in the anemia group were more likely to be African American, have higher ASA class ≥3, and were more likely to receive at least 1 unit of packed red blood cells preoperatively (7.1% versus 0.3%, P < 0.01). Patients in the anemia group had higher rates of 30-day complications (34.5% versus 16.6%, P < 0.01), 30-day readmission related to the principal procedure (11.7% versus 8.7%, P < 0.01), and 30-day mortality (3.1% versus 1%, P < 0.01). On regression analysis, preoperative anemia was independently associated with higher odds of 30-day complications (P < 0.01), but not 30-day readmission, or 30-day mortality (P = 0.464 and P = 0.362 respectively). CONCLUSIONS: Preoperative anemia appears to be associated with postoperative complications. Preoperatively optimizing hemoglobin levels may lead to improved outcomes.

Objective: The purpose of this study is to assess whether the 5-m walk test is associated with 1-year mortality after transcatheter aortic valve replacement. Methods: Included in the analysis were 304 patients who received the 5-m walk test and underwent transcatheter aortic valve replacement from September 2012 to March 2019. They were classified into 3 groups based on their test score: ≤7, >7, and unable to walk. Preprocedure characteristics, postprocedure outcomes, and follow-up outcomes were compared between the groups. Results: For the 5-m walk test, 145 had a score ≤7 (Group N), 111 had a score >7 (Group S), and 48 were unable to walk (Group I). Average age in years was 80.2 ± 8.7 years in Group N, 81.2 ± 9.4 years in Group S, and 79.4 ± 9.2 in Group I (P = .23). The aortic valve mean gradient at discharge was 9.5 ± 4.1 mm Hg in Group N, 10.4 ± 5.5 mm Hg in Group S, and 8.2 ± 4.2 mm Hg in Group I (P = .05). The discharge survival was 97.2% in Group N, 96.4% in Group S, and 95.8% in Group I (P = .76). One-year survival was 92.8% in Group N, 84.1% in Group S, and 75% in Group I (P < .01) after adjusting for preprocedure characteristics. Noncardiac death was 5.1% in Group N, 13.1% in Group S, and 22.7% in Group I (P = .03). This indicates that the 5-m walk test was a risk factor for 1-year mortality. More specifically, a poor 5-m walk test score was associated with 1-year noncardiac mortality. Conclusions: The 5-m walk test score before transcatheter aortic valve replacement was associated with 1-year mortality, especially noncardiac mortality. It may help identify patients at high risk for 1-year mortality.
RESUMEN
INTRODUCTION: Preoperative eGFR has been found to be a reliable predictor of post-operative outcomes in patients with normal creatinine levels who undergo surgery. The aim of our study was to evaluate the impact of preoperative eGFR levels on short-term post-operative outcomes in patients undergoing pancreatectomy. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) pancreatectomy file (2014-2017) was queried for all adult patients (age ≥ 18) who underwent pancreatic resection. Patients were stratified into two groups based on their preoperative eGFR (eGFR < 60 mL/min/1.73m2 and eGFR ≥ 60 mL/min/1.73m2). Outcome measures included post-operative pancreatic fistula, discharge disposition, hospital length of stay, 30-day readmission rate, and 30-day morbidity and mortality. Multivariate logistic regression analysis was performed. RESULTS: A total of 21,148 were included in the study of which 12% (n = 2256) had preoperative eGFR < 60 mL/min/1.73m2. Patients in the eGFR < 60 group had prolonged length of stay, were less likely to be discharged home, had higher minor and major complication rates, and higher rates of mortality. On logistic regression analysis, lower preoperative eGFR (< 60 mL/min/1.73m2) was associated with higher odds of prolonged length of stay [aOR: 1.294 (1.166-1.436)], adverse discharge disposition [aOR: 1.860 (1.644-2.103)], minor [aOR: 1.460 (1.321-1.613)] and major complications [aOR: 1.214 (1.086-1.358)], bleeding requiring transfusion [aOR: 1.861 (1.656-2.091)], and mortality [aOR: 2.064 (1.523-2.797)]. CONCLUSION: Preoperative decreased renal function measured by eGFR is associated with adverse outcomes in patients undergoing pancreatic resection. The results of this study may be valuable in improving preoperative risk stratification and post-operative expectations.

This study is aimed at evaluating the effects of stocking densities and dietary protein levels in the biofloc system on the performance of common carp. Fish (12.09 ± 0.99 g) were transferred to 15 tanks: fish reared at 10 kg/m3 as medium density and fed 35% (MD35) or 25% (MD25) protein and fish reared at 20 kg/m3 as high density and fed 35% (HD35) or 25% (HD25) protein in the biofloc system and control fish reared at MD and fed 35% protein in clear water. After 60 days, fish were subjected to crowding stress (80 kg/m3) for 24 h. The growth of fish was highest in MD35. The feed conversion ratio was lower in MD35 compared to the control and HD groups. The amylase, lipase, protease, and superoxide dismutase and glutathione peroxidase activities in the biofloc groups were significantly higher than in the control. After crowding stress, cortisol and glucose levels in biofloc treatments were significantly decreased compared to the control. After 12 and 24 h stress, lysozyme activity in MD35 was significantly lower than in the HD treatments. Overall, the biofloc system with MD could improve growth and robustness against acute stress in fish. Also, biofloc could compensate 10% reduction of protein in common carp juvenile diet when reared in MD.
RESUMEN
BACKGROUND: The aim of this study is to assess the impact of frailty on short-term outcomes after hepatectomy for colorectal liver metastasis (CRLM). METHODS: Patients were identified using the National Surgical Quality Improvement Program (NSQIP). Patients were divided into 3 categories using the 5-item Modified Frailty Index (mFI). RESULTS: There were 5230 patients included. 52%, 35%, and 13% had mFI scores of 0, 1, and ≥ 2 respectively. Patients with a ≥ 2 mFI score were more likely to experience minor complication (OR 1.34, 95% CI 1.06-1.69), major complication (OR 1.56, 95% CI 1.15-2.12), readmission (OR 1.55, 95% CI 1.12-2.14), unfavorable discharge (OR 2.48, 95% CI 1.62-3.80), 30-day mortality (OR 3.02, 95% CI 1.02-8.95), prolonged length of stay (OR 1.47, 95% CI 1.18-1.83), and bile leak (OR 1.51, 95% CI 1.02-2.24). CONCLUSION: Frailty is associated with increased post-operative complications. The 5-item mFI can guide risk stratification, optimization, and counseling.

It has been recognized that wall shear stress plays an important role in the development of Bicuspid Aortopathy (BA), but the intrinsic mechanism is not well elucidated. This study aims to explore the underlying relationship between hemodynamical forces and pathological phenomenon. Total RNA was prepared from aortic wall tissues collected from 20 BA patients. RNA sequencing, bioinformatic analysis and quantitative reverse-transcription PCR validation identified nine miRNAs that were up-regulated in the aortic part exposed to high wall shear stress compared to the low wall shear stress control, and six miRNAs that were down-regulated. Among these candidates, miR-34a and miR-125a, both down-regulated in the high wall shear stress parts, were shown to be potential inhibitors of the metalloproteinase 2 gene. Luciferase reporter assays confirmed that both miRNAs could inhibit the expression of metalloproteinase 2 mRNA in CRL1999 by complementing with its 3' untranslated region. Conversely, immunofluorescence assays showed that inhibition of miR-34a or miR-125a could lead to increased metalloproteinase 2 protein level. On the other hand, both miR-34a and miR-125a were shown to alleviate stretch-induced stimulation of metalloproteinase 2 expression in CRL1999 cells. The results suggested that miR-34a and miR-125a might be implicated in wall shear stress induced aortic pathogenesis due to their apparent regulatory roles in metalloproteinase 2 expression and extracellular matrix remodeling, which are key events in the weakening of aortic walls among BA patients.

BACKGROUND: Intracranial arachnoid cysts are common, cerebrospinal fluid-filled, innocent lesions that are usually detected incidentally on brain imaging. They may rupture and complicate due to subdural hematoma or hygroma after minor trauma. Authors present two cases of ruptured middle cranial fossa arachnoid cysts in adolescent (12-year-old and 15-year-old) Afghan boys presenting with subdural hygroma after minor trauma. CONCLUSION: Imaging work-up is necessary for symptomatic patients following minor head trauma as incidentally detected ruptured intracranial arachnoid cysts can be responsible for the symptoms.

PURPOSE: Surgery especially in the emergent setting carries higher rates of morbidity and mortality. The aim of our study was to evaluate the impact of preoperative anemia on outcomes for patients undergoing colectomy for acute diverticulitis in both elective and emergent settings. METHODS: We performed a 4-year analysis of the ACS-NSQIP and included adult patients with acute diverticulitis who underwent colectomy. Patients were stratified into two groups based on preoperative hemoglobin levels, preop anemia and no-preop Anemia. Outcome measures were 30-day complications, anastomotic leaks, readmissions, mortality, and intra-/postoperative blood transfusion. We also performed a sub-analysis for patients who underwent emergent colectomy. RESULTS: Six thousand nine hundred sixty-three patients were included in the analysis, of which 37% (n = 2571) had preoperative anemia. Patients in the anemia group were more likely to have higher ASA class and receive blood 72-h preoperatively (5.4% vs. 0.2%, p < 0.01). Patients in the anemia group had higher rates of complications (35.4% vs. 24.7%, p < 0.01), unplanned readmission (9.2% vs 7.2%, p < 0.01), mortality (4.5% vs. 1.8%, p < 0.01), and intra/postoperative transfusion requirement (21% vs. 3.8%, p < 0.01) with no difference in rate of anastomotic leaks. On sub-analysis, 39% of the cases were completed in an emergent setting, 85% of which were due to perforation. Patients with preoperative anemia that underwent colectomy in an emergent setting had higher odds of intra/postoperative blood transfusion (OR 51.6, CI 3.87-6.87, p < 0.01) with no statistical significance in 30-day complications (p = 0.51). CONCLUSION: Preoperative anemia in patients undergoing colectomy for acute diverticular disease is associated with higher odds complications, readmissions, and intra/postoperative blood transfusions.

BACKGROUND: Preoperative neoadjuvant chemotherapy (NAC) for colon cancer in advanced stages is associated with improved outcomes and tumor regression. The aim of our study was to identify outcomes in patients with colon cancer who received preoperative NAC. METHODS: A 4-year analysis of the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) was performed. We included patients with locally advanced colon cancer (non-metastatic T3, T4 with or without nodal involvement) who underwent colon cancer resection. Patients were stratified into two groups (NAC and No-NAC). Our outcome measures were anastomotic leaks, hospital length of stay (LOS), 30-day complications, 30-day mortality, and 30-day readmissions. We performed a multi-variable logistic regression analysis. RESULTS: We analyzed 90,055 patients of which 7694 (NAC: 7.8 % (n = 599) and No-NAC: 92.2% (n = 7095)) met the inclusion criteria and included in the analysis. Mean age was 67 ± 13 years, 51% were males, and 72% were whites. Patients in the NAC group were more likely to be younger (60 ± 12 years vs. 68 ± 13 years, p < 0.01) and males (62% vs. 50%, p < 0.01) compared to No-NAC. On regression analysis, preoperative NAC was independently associated with higher odds of anastomotic leak (OR 1.35 [1.05-1.97], p = 0.03) and 30-day readmission (OR 1.54 [1.24-2.05], p < 0.01) in reference to No-NAC. However, no association was found between NAC and 30-day complications and 30-day mortality. CONCLUSIONS: Preoperative NAC might be associated with adverse outcomes of anastomotic leaks and 30-day readmissions, however does not appear to impact 30-day complications nor 30-day mortality.

Sustainable aquaculture arises as key to increase food production in the coming years. However, the sector still faces many challenges such as the exposure of the cultured animals to pesticide-contaminated water. Pesticides used in agriculture can reach aquaculture systems either directly (integrated-agriculture aquaculture practices) or indirectly (soil leakage) and cause a broad range of ecotoxicological effects on cultured fish and shellfish. Here, we studied how glyphosate affects several haematological, biochemical, and immune parameters in common carp (Cyprinus carpio) fingerlings, the fourth most important cultured fish species worldwide. We also evaluated the potential of dietary supplementation with black seed (Nigella sativa, 0.25, 0.5 and 1%) to lower glyphosate-associated toxicity. Our results showed that 14-day sub-lethal exposure of common carp fingerlings to glyphosate increases oxidative stress, decreases antioxidant defences, affects several metabolic pathways, and induced immune depression. Furthermore, we showed that fish fed with N. sativa-enriched diets at 0.25, 0.5 and 1% for 60 days coped better with glyphosate exposure than control fish and displayed more stable levels of biochemical serum parameters (total protein, albumin, triglycerides, low-density lipoprotein LDL), cholesterol and high-density lipoprotein HDL), higher levels of immune defences (lysozyme and immunoglobulin) and higher antioxidant enzymes (superoxide dismutase SOD, glutathione peroxidase GPx) than control fish. Fish fed with all enriched diets also displayed lower lipid peroxidation (malondialdehyde MDA), lower metabolic enzymes (alanine aminotransferase ALT, aspartate aminotransferase AST and alkaline phosphatase ALP) levels in blood serum and lower cortisol levels than control fish. Altogether, our results show that dietary inclusion of black seed can be used as a sustainable bio-remediation strategy, mitigating many of the negative effects of glyphosate exposure in fish.

BACKGROUND: Previous studies have documented increased complications following pancreaticoduodenectomy in patients who undergo preoperative biliary stenting (PBS). However, in the modern era, the vast majority of patients with jaundice are stented. We hypothesized that there is no difference in short-term postoperative outcomes between PBS and no PBS in patient with obstructive jaundice undergoing pancreaticoduodenectomy. METHODS: We performed an analysis using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) participant use file (2014-2017). Patients who received neoadjuvant chemotherapy and required stenting were excluded from the analysis. A propensity-matched analysis was performed to select obstructive jaundice patients who underwent PBS and those who did not with similar characteristics prior to pancreaticoduodenectomy. Short-term postoperative outcome measures included superficial surgical site infection (S-SSI), deep surgical site infection (D-SSI), hospital length of stay (LOS), postoperative pancreatic fistula (POF), hospital readmission, minor morbidity (Clavien-Dindo I-II), major morbidity (Clavien-Dindo III, IV, V), and 30-day mortality. RESULTS: A total of 5851 patients with obstructive jaundice underwent pancreaticoduodenectomy without neoadjuvant chemotherapy. 81.6% underwent PBS. Based on the propensity-matched analysis, 927 patients who received PBS and 927 patients who did not were selected for comparing the outcomes between the two groups. There was no significant difference in outcome measures between the two groups with respect to S-SSI (OR 1.30 , 95% CI = 0.94-1.80, p = 0.12), D-SSI (OR 1.07, 95% CI = 0.81-1.41, p = 0.62), POF (OR 1.11, 95% CI = 0.87-1.42, p = 0.40), hospital readmission (OR 0.99, 95% CI = 0.77-1.27, p = 0.94), minor morbidity (OR 0.91, 95% CI = 0.76-1.11, p = 0.36), major morbidity (OR 0.84, 95% CI = 0.67-1.06, p = 0.14), and 30-day mortality (OR 1.05, 95% CI = 0.57-1.95, p = 0.87). Patients who underwent PBS were more likely to have shorter LOS (RR 0.87, 95% CI = 0.81-0.93, p < 0.0001). CONCLUSION: Contrary to previously reported studies, there was no increased risk of short-term postoperative outcomes after pancreaticoduodenectomy between PBS and N-PBS in a propensity-matched analysis. Preoperative biliary stenting is safe and does not need to be avoided before surgical intervention in patients who present with obstructive jaundice.

BACKGROUND: Gallbladder cancer has a poor prognosis, and surgery is the only curative treatment. However, lymphadenectomy has been underperformed. We evaluate the trend of lymphadenectomy in the United States and its impact on survival. METHODS: This is a cohort study of patients who underwent gallbladder cancer surgery between 2004 and 2016. Trend analysis of the rate of lymphadenectomy and the number of lymph nodes (LNs) removed were examined. The impact of lymph node status and different LN staging systems on survival was examined. RESULTS: Of the 4577 patients identified, 69.9% were female, the mean age was 71.0 (±12.4), 87.2% had ≥ T2, and only 50.3% (n = 2302) received lymphadenectomy. Although the rate of lymphadenectomy and the number of LNs removed increased during the study period, both with P < 0.0001, the rate of patients who received examination of ≥6 LNs remained low, 13.6% in 2016. Adjusted regression analysis showed that patients without LN examination had worse overall survival than patients with LN positive disease, HR: 1.11 (95% CI: 1.01, 1.22). Concordance index analysis revealed that LN ratio (LNR) and Log odds of positive LN (LODDS) did not improve the ability of the American Joint Commission on Cancer (AJCC) staging in predicting 5-y survival rate. CONCLUSIONS: Lack of LN examination is associated with worse survival than LN positive disease. Although the rate of LN examination and number of LNs retrieved have increased from 2004 to 2016, they remained low. LNR and LODDS staging systems added no benefit to AJCC staging ability in predicting a 5-y survival rate.

BACKGROUND: Thromboprophylaxis in patients with spinal trauma is often delayed due to the risk of bleeding and expansion of the intraspinal hematoma (ISH). Our study aimed to assess the safety of early initiation of thromboprophylaxis in patients with operative spinal trauma (OST). METHODS: We performed a 2014-2017 retrospective analysis of our level I trauma registry and included all adult patients with isolated OST who received low-molecular-weight heparin (LMWH). Patients were stratified into early (≤48 h) and late (>48 h) initiation of LMWH groups. Outcomes were a decline in hemoglobin level, packed red blood cell transfusion, and progression of ISH. We performed multivariable logistic regression. RESULTS: We identified a total of 526 patients (early: 332, late: 194). Mean age was 46 ± 22y, and the median spine abbreviated injury scale was 3 [2-4]. After thromboprophylaxis, 1.5% (8) of the patients had progression of ISH and 1% (5) underwent surgical decompression of the spinal canal. There was no difference between the two groups regarding the rate of postprophylaxis ISH progression (1.5% versus 1.6%, P = 0.11) or surgical decompression (0.9% versus 1.1%, P = 0.19). Patients who received LMWH within 48 hrs had a lower incidence of clinically significant deep vein thrombosis (2.4% versus 6.8%, P = 0.02), but no difference in pulmonary embolism (0.6% versus 1.6%, P = 0.33) or mortality (1.2% versus 1.5%, P = 0.41). On regression analysis, there was no difference regarding decline in hemoglobin levels (ß = 0.079, [-0.253 to 1.025]; P = 0.23) or number of packed red blood cell units transfused (ß = -0.011, [-0.298 to 0.471]; P = 0.35). CONCLUSIONS: Thromboprophylaxis with LMWH within the first 48 h in patients with OST is safe and efficacious. Prospective studies are needed to further validate their risk-benefit ratio. LEVEL OF EVIDENCE: Level III therapeutic.

OBJECTIVE: The International Patterns of Opioid Prescribing study compares postoperative opioid prescribing patterns in the United States (US) versus the rest of the world. SUMMARY OF BACKGROUND DATA: The US is in the middle of an unprecedented opioid epidemic. Diversion of unused opioids contributes to the opioid epidemic. METHODS: Patients ≥16 years old undergoing appendectomy, cholecystectomy, or inguinal hernia repair in 14 hospitals from 8 countries during a 6-month period were included. Medical records were systematically reviewed to identify: (1) preoperative, intraoperative, and postoperative characteristics, (2) opioid intake within 3 months preoperatively, (3) opioid prescription upon discharge, and (4) opioid refills within 3 months postoperatively. The median/range and mean/standard deviation of number of pills and OME were compared between the US and non-US patients. RESULTS: A total of 4690 patients were included. The mean age was 49 years, 47% were female, and 4% had opioid use history. Ninety-one percent of US patients were prescribed opioids, compared to 5% of non-US patients (P < 0.001). The median number of opioid pills and OME prescribed were 20 (0-135) and 150 (0-1680) mg for US versus 0 (0-50) and 0 (0-600) mg for non-US patients, respectively (both P < 0.001). The mean number of opioid pills and OME prescribed were 23.1â±â13.9 in US and 183.5â±â133.7âmg versus 0.8â±â3.9 and 4.6â±â27.7âmg in non-US patients, respectively (both P < 0.001). Opioid refill rates were 4.7% for US and 1.0% non-US patients (P < 0.001). CONCLUSIONS: US physicians prescribe alarmingly high amounts of opioid medications postoperatively. Further efforts should focus on limiting opioid prescribing and emphasize non-opioid alternatives in the US.

BACKGROUND: Cognitive impairment (CI) is common in geriatric patients. We aimed to evaluate the prevalence and impact of CI on outcomes in geriatric patients undergoing emergency general surgery (EGS). METHODS: We performed a (2017-2018) prospective analysis of patients (age ≥65y) who underwent EGS. Cognition was assessed using the Montreal Cognitive Assessment (MoCA). Patients were stratified into: CI (MoCA score<26) and no-CI (MoCA≥26). Outcomes were the prevalence of CI, in-hospital complications, discharged to rehab/skilled nursing facility (SNF), and mortality. RESULTS: A total of 142 patients were enrolled. Overall prevalence of CI was 20%. Patients with CI had higher rates of complications (OR 1.6 [1.4-1.9]; p = 0.01), and discharge to rehab/SNF (OR 2.2 [2.0-2.5]; p = 0.03). There was no difference in mortality (OR 1.1 [0.6-1.8]; p = 0.24) between the 2 groups. CONCLUSION: One in five geriatric EGS patients has CI. It is associated with higher complications and adverse discharge. Cognitive assessment should be included in preoperative risk stratification.

BACKGROUND: Nonneurological organ dysfunction (NNOD) occurs after traumatic brain injury (TBI) and is associated with mortality. The aim of our study was to evaluate the prevalence of NNOD and its association with outcomes in pediatric patients with TBI. We hypothesized that NNOD is associated with worse outcomes in pediatric patients with severe TBI. METHODS: We performed a 4-year (2013-16) analysis of our prospectively maintained TBI database. All patients (ageâ¯<â¯18) with an isolated-severe TBI (head-abbreviated injury scale: AISâ¯≥â¯3 & extracranial-AISâ¯<â¯3) were included. NNOD was measured using the pediatric multiple organ dysfunction (P-MOD) score. Outcomes were in-hospital mortality, Glasgow Outcome Scale-Extended (GOS-E), and adverse discharge disposition: rehabilitation or skilled nursing facility (SNF). Regression analysis was performed. RESULTS: We analyzed 292 patients. Mean age was 11⯱â¯6 years, 57% were male and the mortality rate was 18.1%. The incidence of NNOD was 35%. The most common dysfunctional organ system was the respiratory (25%) followed by the cardiovascular (12%). On regression analysis, the presence of at least one NNOD was independently associated with in-hospital mortality (OR 2.1 [1.7-2.9]; pâ¯<â¯0.01), low GOS-E (OR 1.8 [1.5-2.3]; pâ¯<â¯0.01), and SNF disposition (OR 1.7 [1.2-2.1]; pâ¯<â¯0.01). CONCLUSION: NNOD develops in one of every three severe TBI pediatric patients and is independently associated with adverse outcomes. Identification of NNOD in pediatric TBI and focusing on management of NNOD could improve outcomes. LEVEL OF EVIDENCE: III Prognostic.
