Outcomes and Cost-Analysis of Open Versus Endovascular Abdominal Aortic Aneurysm Repair in a Developing Country: A 15-year Experience at a Tertiary Medical Center.

BACKGROUND: Endovascular aortic aneurysm repair (EVAR) has become the most common procedure for treating abdominal aortic aneurysms based on multiple studies conducted in the western world. The implication of such findings in developing countries is not well demonstrated. The objective of this study was to compare medical outcomes and costs of EVAR and open surgical repair (OSR) in a developing country. METHODS: This is a retrospective study of all patients undergoing elective abdominal aortic aneurysm repair between 2005 and 2020 at a tertiary medical center in a developing country. Medical records were used to retrieve demographics, comorbidities, and perioperative complications. Medical records were also used to provide data on the need of reintervention, date of last follow-up, and mortality. RESULTS: The study included a total of 164 patients. Median follow-up time was 41 months. The mean age was 69.9 +/- 7.84 years and 90.24% (n = 148) of patients were males. Regarding long-term mortality outcomes, no significant difference was detected between both groups; OSR patients had a survival rate of 91.38% and 74.86% at 5 and 10 years, compared to 77.29% and 56.52% in the EVAR group (P value = 0.10). Both groups had comparable long-term reintervention rates (P value = 0.334). The OSR group was charged significantly less than the EVAR group ($27,666.35 vs. $44,528.04, P value = 0.008). CONCLUSIONS: OSR and EVAR have comparable survival and reintervention outcomes. Unlike what was reported in developed countries, patients undergoing OSR in countries with low hospital stay costs incur lower treatment costs.

General Versus Locoregional Anesthesia in TEVAR: An NSQIP Analysis.

BACKGROUND: Thoracic Endovascular Aortic Repair (TEVAR) is a minimally invasive surgery for repairing thoracic aneurysms and dissections. This study aims to compare postoperative outcomes of TEVAR performed under general versus locoregional anesthesia. METHODS: Utilizing the 2008-2019 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database, patients older than the age of 18 years who received TEVAR, were identified using the following current procedural terminology codes: 33,880, 33,881, 33,883, 33,884, or 33,886. Patients who underwent concomitant procedures, those with both thoracoabdominal and abdominal aortic pathologies, and trauma cases were excluded. Standard descriptive statistics, in addition to χ2, Fisher's exact test, and Mann-Whitney U-tests were used to compare patient baseline characteristics and postoperative outcomes between general and locoregional anesthesia groups as appropriate. Univariable and multivariable logistic regression analyses were performed to assess independent predictors of hospital length of stay (LOS) greater than 7 days. RESULTS: Of the 1,028 patients included in the study, 86.5% received general anesthesia, and 13.5% received locoregional anesthesia, such as local anesthesia with monitored anesthesia care or regional anesthesia. No significant differences were found between patients receiving locoregional versus general anesthesia in mortality (3.6% vs. 7.9%, respectively, P = 0.071) and morbidity (18.7% and 24.8%, respectively, P = 0.121) within 30 days post-TEVAR, including any wound, pulmonary, thromboembolic, renal, septic, and cardiac arrest complications. Patients who received general anesthesia had significantly higher median LOS compared to those who received locoregional anesthesia [5 days (interquartile range (IQR): 3-10) versus 4 days (IQR: 2-7), P = 0.002], with 34.3% of the general anesthesia group having an LOS greater than 7 days compared to 21.6% of locoregional anesthesia group, P = 0.003. On multivariable logistic regression analysis, general anesthesia was found to be an independent predictor of prolonged LOS greater than 7 days (odds ratio (OR): 1.72, 95% confidence interval (CI): 1.05-2.81, P = 0.031). CONCLUSIONS: Locoregional anesthesia results in significantly lower postoperative hospital LOS with similar postoperative mortality and morbidity compared to general anesthesia in patients undergoing TEVAR.

Thromboembolectomy for acute lower limb ischemia: Contemporary outcomes of two surgical methods from a single tertiary center.

OBJECTIVES: The current treatment of acute lower limb ischemia (ALLI) includes open surgical and percutaneous pharmaco-mechanical thromboembolectomy (TE). We hereby report our results with open surgical TE over a 10-year period and compare our outcomes using routine fluoroscopic assisted TE (FATE) with blind and selective on demand fluoroscopic-assisted TE (BSTE). METHODS: This is a retrospective analysis of all patients who underwent open surgical TE for acute lower limb ischemia at a single tertiary center between 2008 and 2018. Patients were divided into a group who underwent BSTE and another who underwent routine FATE. Data on presentation, medical history, surgery performed, and short-term outcomes were retrieved from medical record. Comparison between baseline characteristics and outcomes of both groups were made using t-test and chi-square analysis. RESULTS: Over 10 years, 108 patients underwent surgical TE. Thirty-day mortality rate and 30-day major lower extremity amputation rate in the cohort were 12.0% and 6.5%, respectively. On subgroup analysis, 53 patients were treated by BSTE and 55 patients by FATE. There was no significant difference in 30-day mortality rate (11.3% vs 12.7%, p-value = .82) and 30-day major amputation rate (9.4% vs 3.6%, p-value = .454) between the two groups. Local anesthesia was more frequently performed in patients undergoing FATE (58.2% vs 24.5%, p-value < .001). More than one arteriotomy was more frequently required in patients undergoing BSTE (2.6% vs 45.5%, p-value < .001). Patients with infrapopliteal involvement undergoing FATE required less further interventions such as patch angioplasty (2.6% vs 36.4%, p-value < .001) and bypass (2.6% vs 22.7%, p-value = .01). CONCLUSION: ALLI remains a disease of high morbidity and mortality. Open surgical TE offers an effective approach to treat ALLI. The addition of fluoroscopy to the conduction of TE could be associated with valuable benefits, especially in patients with infra-popliteal involvement. Randomized controlled trials are needed to objectively assess the therapeutic potential of FATE.

Incidence and Predictors of Surgical Site Infection Complications in Diabetic Patients Undergoing Lower Limb Amputation.

BACKGROUND: Surgical site infections (SSIs) following lower extremity amputations (LEAs) are a major cause of patient morbidity and mortality. The objectives of this study are to investigate the annual incidence of SSI and risk factors associated with SSI after LEA in diabetic patients. METHODS: LEAs performed on diabetic patients between 2005 and 2017 were retrospectively analyzed from the American College of Surgeons National Surgical Quality Improvement Program database. Incidence rates were calculated and analyzed for temporal change. Multivariable logistic regression was conducted to identify the independent predictors of SSIs in LEA. RESULTS: In 21,449 diabetic patients, the incidence of SSIs was 6.8% after LEA, with an overall decreasing annual trend (P = 0.013). Amputation location (below-knee in reference to above-knee) [OR (95% CI): 1.35 (1.20 - 1.53), P <0.001], smoking [OR (95% CI): 1.25 (1.11 - 1.41), P <0.001)], female sex [OR (95% CI): 1.16 (1.03 - 1.30)], preoperative sepsis [OR (95% CI): 1.24 (1.10 - 1.40), P <0.001], P = 0.013], emergency status [OR (95% CI): 1.38 (1.17 - 1.63), P <0.001], and obesity [OR (95% CI): 1.59 (1.12 - 2.27), P = 0.009] emerged as independent predictors of SSIs, while moderate/severe anemia emerged as a risk-adjusted protective factor [OR (95% CI): 0.75 (0.62 - 0.91), P = 0.003]. Sensitivity analysis found that moderate/severe anemia, not body mass index (BMI) class, remained a significant risk factor in the development of SSIs in below-the-knee amputations; in contrast, higher BMI, not preoperative hematocrit, was significantly associated with an increased risk for SSI in above-the-knee amputations. CONCLUSIONS: The incidence of SSIs after LEA in diabetic patients is decreasing. Overall, below-knee amputation, smoking, emergency status, and preoperative sepsis appeared to be associated with SSIs. Obesity increased SSIs in above-the-knee amputations, while moderate/severe preoperative anemia appears to protect against below-the-knee SSIs. Surgeons should take predictors of SSI into consideration while optimizing care for their patients, and future studies should investigate the role of preoperative hematocrit correction and how it may influence outcomes positively or negatively.

A Quality Assessment of the Information Accessible to Patients on the Internet About the Whipple Procedure.

BACKGROUND: The Internet has become a central source of information on health-related issues. The aim of this study is to assess the quality and readability of online information present on the Whipple surgical procedure by applying recognized scoring tools. METHODS: A search using the top three online search engines (Google, Bing and Yahoo) was conducted in July 2020. Websites were classified as academic, physician, commercial or unspecified. The quality of information was assessed using the JAMA and DISCERN assessment instruments and presence of a HONcode seal. Readability was assessed using the Flesch Reading Ease Score (FRES). RESULTS: A total of 34 unique sources were included in our study. The average JAMA and DISCERN scores of all websites were 2.22 ± 0.48 and 47.28 ± 1.17, respectively, with a median of 1.9 (range 0-4) and 47 (range 18-71), respectively. Website classification distribution was 38% academic, 18% commercial, 9% unspecified, and 1% from physician-based websites. Physician websites had the highest JAMA score with a mean of 3 ± 0.46. Unspecified websites had the highest DISCERN score with a mean of 54.60 ± 1.09. Only 3 websites had the HONcode seal. Physician websites had a significantly higher JAMA mean score than academic websites (p-value = 0.004). Readability was difficult and is on the level of university students. CONCLUSION: The results of this study show a poor quality of online information present on the Whipple surgery. Academic and physician websites need to improve the quality of their websites on the procedure. More HONcode-certified websites are needed as they are the best source for information on this operation.

Treatment and Prognosis of Hepatic Epithelioid Hemangioendothelioma: A SEER Database Analysis.

BACKGROUND: Hepatic epithelioid hemangioendothelioma (HEH) is a rare tumor that can affect multiple organs. Little is known about the pathophysiology, clinical course and management of this disease. The aim of this study is to determine survival rates and elucidate the role of various prognostic factors and therapeutic modalities as compared to surgery on patients with HEH. METHODS: A retrospective analysis on patients diagnosed with HEH between 2004 and 2016 was performed utilizing the SEER database. Kaplan-Meier curves were constructed to determine overall and cancer-specific survival, and the log-rank test was used to compare between groups. To explore prognostic factors and treatment outcomes, univariable and multivariable Cox proportional hazard models were developed. RESULTS: A total of 353 patients with HEH (median age: 50.4 years) were identified. The most common surgery performed was liver resection (90.8%). One-year OS in the surgical group and non-surgical group was 86.6% and 61.0%, respectively, while 5-year OS was 75.2% and 37.4%, respectively. On multivariable analysis, surgery emerged as a favorable prognostic factor [HR (95%CI): 0.404 (0.215-0.758) p value = 0.005]. Age > 65 years [HR (95%CI): 2.548 (1.442-4.506) p value = 0.001] and tumor size > 10 cm [HR (95%CI): 2.401 (1.319-4.37) p value = 0.004] were shown to be poor survival prognostic factors. CONCLUSION: HEH is a rare disease that is poorly understood. Surgical intervention is associated with improved survival rates. Multicenter prospective collaborations are needed to improve our limited knowledge about this neoplasm and determine the optimal treatment strategy.

Hypoalbuminemia is Associated with Mortality in Patients Undergoing Lower Extremity Amputation.

BACKGROUND: Poor nutritional status is common among patients undergoing lower extremity amputation (LEA). In this study, the association between preoperative hypoalbuminemia, a marker for malnutrition, and postoperative mortality in patients undergoing LEA was explored. METHODS: Data on patients undergoing LEA between 2005 and 2017 were retrospectively analyzed from the prospectively collected American College of Surgeons National Surgical Quality Improvement Program database. Patients were divided into clinically relevant categories based on their serum albumin level (<2.5, 2.5-3.39, ≥3.4 g/dl) and were further stratified according to amputation level. Operative death was compared across groups and multivariable logistic regression was performed to estimate risk-adjusted odds ratio (AOR). RESULTS: In 35,383 patients, the rate of 30-day postoperative mortality was 7.6% (n = 2693). Mortality rate was highest in patients with very low albumin levels (11%) as compared to low (6.8%) and normal levels (3.9%). On multivariable analysis, lower albumin levels emerged as a risk-adjusted independent predictor of mortality. After risk-adjustment, patients with very low albumin levels (AOR [95% CI]: 2.25 [1.969-2.56], P < 0.001) and low albumin levels (AOR [95% CI]: 1.42 [1.239-1.616], P < 0.001) had higher odds of mortality when compared to patients with normal albumin levels. On sensitivity analysis, a similar trend was seen in patients undergoing above knee amputation but not in patients undergoing minor amputations. CONCLUSIONS: In patients undergoing major LEA, hypoalbuminemia is associated with an increased risk of postoperative mortality in a dose response manner, specifically in above knee amputations. Monitoring and optimizing patients' nutritional status before surgery, when possible, may be warranted and should be further explored.

Major lower extremity amputations in a developing country: 10-Year experience at a tertiary medical center.

BACKGROUND: Lower extremity amputation (LEA) is a major surgical procedure with a high risk of significant morbidity and mortality. The objective of this study was to describe mortality and functionality outcomes following this procedure in a developing country. METHODS: This is a retrospective study of all patients undergoing LEA for non-traumatic etiology between 2007 and 2017. Medical records were used to retrieve demographics, comorbidities, and perioperative complications of identified patients. Patients were contacted to follow-up on their medical, postoperative care, and ambulatory status. Mortality and postoperative functionality rates were analyzed. RESULTS: The study included 78 patients. Median follow-up duration was 24 months. Hypertension (81%) and diabetes (79%) were the most common comorbidities. Mortality rates at 30 days, 1, and 5 years were 10.3, 29.2, and 65.5%, respectively. Mortality was significantly associated with age > 70 at amputation (p = 0.042), hypertension (p = 0.003), chronic kidney disease (p = 0.031), and perioperative sepsis (p = 0.01). Only 1.6% of patients were discharged into a specialized care center, and only 27% of patients were ambulatory postoperatively, although 90.5% were fitted with a prosthesis. CONCLUSIONS: Survival following major amputation in a developing country is currently comparable to more developed regions of the world. Major discrepancy seems to exist in ambulatory status following the procedure. Discharge placement policies should be properly set, and rehabilitation centers funding should be increased. Awareness may also be warranted to educate patients and families about the value and positive impact of rehabilitation centers.

Physical injuries and burns among refugees in Lebanon: implications for programs and policies.

BACKGROUND: Refugees are prone to higher risks of injury due to often austere living conditions, social and economic disadvantages, and limited access to health care services in host countries. This study aims to systematically quantify the prevalence of physical injuries and burns among the refugee community in Western Lebanon and to examine injury characteristics, risk factors, and outcomes. METHODS: We conducted a cluster-based population survey across 21 camps in the Beqaa region of Lebanon from February to April 2019. A modified version of the 'Surgeons Overseas Assessment of Surgical Need (SOSAS)' tool (Version 3.0) was administered to the head of the refugee households and documented all injuries sustained by family members over the last 12 months. Descriptive and univariate regression analyses were performed to understand the association between variables. RESULTS: 750 heads of households were surveyed. 112 (14.9%) households sustained injuries in the past 12 months, 39 of which (34.9%) reported disabling injuries that affected their work and daily living. Injuries primarily occurred inside the tent (29.9%). Burns were sustained by at least one household member in 136 (18.1%) households in total. The majority (63.7%) of burns affected children under 5 years and were mainly due to boiling liquid (50%). Significantly more burns were reported in households where caregivers cannot lock children outside the kitchen while cooking (25.6% vs 14.9%, p-value = 0.001). Similarly, households with unemployed heads had significantly more reported burns (19.7% vs. 13.3%, p value = 0.05). Nearly 16.1% of the injured refugees were unable to seek health care due to the lack of health insurance coverage and financial liability. CONCLUSIONS: Refugees severely suffer from injuries and burns, causing substantial human and economic repercussions on the affected individuals, their families, and the host healthcare system. Resources should be allocated toward designing safe camps as well as implementing educational awareness campaigns specifically focusing on teaching about heating and cooking safety practices.

National trends in cholecystectomies in the US: a 15-year comparison of two surgical approaches.

BACKGROUND: The two approaches for performing cholecystectomy are open and laparoscopic ones. This study aims to characterize national trends of cholecystectomies in the United States (US) and determine differences by approach, age group, primary payer, teaching status and location of healthcare center. METHODS: Retrospective analysis of patients undergoing cholecystectomy was done using the US National Inpatient Sample from 1997 to 2011. Trends in open and laparoscopic cholecystectomy were analyzed, as well as comparison between age groups, primary payer, location and teaching status of hospitals operations were performed at. RESULTS: Around 6 million cholecystectomies performed from 1997 to 2011. The laparoscopic approach was significantly more common than the open (P<0.001). A significant decrease in open cholecystectomies is seen since 1997. Age group of 65-84 had significantly the most cases in the open approach (P<0.001), while in laparoscopic the 18-44 age group had the significantly highest amount (P<0.001). Medicare covered the most cases for open, while private insurance covered the most in the laparoscopic approach. Most cases were performed in urban, private non-profit, non-teaching hospitals in both groups. In the laparoscopic group the South had a significantly higher (P<0.001) number of cases compared to all other US regions. CONCLUSIONS: Cholecystectomies remained constant from 1997 to 2011. The number of open cholecystectomies decreased over time in favor of laparoscopic ones. More funding should be given to private non-teaching hospitals as they perform the majority of cholecystectomies nationwide. Better management of cholecystectomy risk factors is needed in the South.

Clinical Trials in Hepatopancreatobiliary Surgery: Assessing Trial Characteristics, Early Discontinuation, Result Reporting, and Publication.

BACKGROUND: Hepatopancreaticobiliary (HPB) diseases carry high morbidity despite efforts aimed at their reduction. An assessment of their trial characteristics is paramount to determine trial design adequacy and highlight areas for improvement. As such, the aim of this study is to assess HPB surgery trial characteristics, summarize logistic, financial, and practical reasons behind early discontinuation, and propose potential interventions to prevent this in the future. METHODS: All clinical trials investigating HPB surgery registered on ClinicalTrials.gov from October 1st, 2007 (inclusive), to April 20th, 2021 (inclusive), were examined. Trial characteristics were collected including, but not limited to, study phase, duration, patient enrollment size, location, and study design. Peer-reviewed publications associated with the selected trials were also assessed to determine outcome reporting. RESULTS: A total of 1776 clinical trials conducted in 43 countries were identified, the majority of which were conducted in the USA. Of these trials, 32% were reported as "completed" whereas 12% were "discontinued." The most common cause of trial discontinuation was low accrual, which was reported in 37% of terminated studies. These resulted in 413 published studies. Most trials had multiple assignment, randomized, or open-label designs. Treatment was the most common study objective (73%) with pharmacological therapy being the most commonly studied intervention. CONCLUSIONS: The main reasons for early discontinuation of clinical trials in HPB surgery are poor patient recruitment and inadequate funding. Improved trial design, recruitment strategies and increased funding are needed to prevent trial discontinuation and increase publication rates of HPB surgery clinical trials.

Is breast conservation superior to mastectomy in early stage triple negative breast cancer?

PURPOSE: Compare overall survival (OS) and breast cancer-specific survival (BCSS) outcomes of breast conservative therapy (BCT) and mastectomy in a large cohort of patients with early-stage triple negative breast cancer (TNBC), using a propensity score-based matching approach. METHODS: Surveillance, Epidemiology, and End Results (SEER) database was used to study the role of RT in early stage TNBC. Primary end points were OS and BCSS. Cox proportional hazard regression models and Kaplan-Meier plots were used to generate the desired outcomes. Propensity score matching was done to minimize bias. RESULTS: 12,761 patients with T1-2N0M0 TNBC as their first malignancy were retrieved. Of these 7237 had lumpectomy with RT, and 5524 had mastectomy only. Age, race, marital status, tumor laterality, grade and stage, and receipt of chemotherapy were prognostic variables for OS and BCSS. Among 4848 matched subjects, the 5-year OS was significantly higher in patients with lumpectomy and RT (89%) compared to mastectomy alone (84.5%) (p-value <0.001). Similarly, BCSS was significantly higher in patients with lumpectomy and RT (93%) compared to mastectomy alone (91%) (p-value <0.001). On subgroup analysis, patients who are younger than 40 had similar survival outcomes after either mastectomy alone or lumpectomy with RT. However, those who are older than 60, have any grade or T stage had better survival outcomes with lumpectomy and RT. CONCLUSIONS: Overall, lumpectomy followed by RT is associated with better OS and BCSS compared to mastectomy in T1-2N0M0 TNBC patients. Further research is needed to determine the optimal treatment strategy for specific patient subgroups.

American college of surgeons NSQIP pancreatic surgery publications: A critical appraisal of the quality of methodological reporting.

BACKGROUND: The use of ACS-NSQIP has increased in pancreatic surgery (PS) research. The aim of this study is to critically appraise the methodological reporting of PS publications utilizing the ACS-NSQIP database. STUDY DESIGN: PubMed was queried for all PS studies employing the ACS-NSQIP database published between 2004 and 2021. Critical appraisal was performed using the JAMA-Surgery Checklist, STROBE Statement, and RECORD Statement. RESULTS: A total of 86 studies were included. Median scores for number of fulfilled criteria for the JAMA-Surgery Checklist, STROBE Statement, and RECORD Statement were 6, 20, and 6 respectively. The most commonly unfulfilled criteria were those relating to discussion of missed data, compliance with IRB, unadjusted and adjusted outcomes, providing supplementary/raw information, and performing subgroup analyses. CONCLUSION: An overall satisfactory reporting of methodology is present among PS studies utilizing the ACS-NSQIP database. Areas for improved adherence include discussing missed data, providing supplementary information, and performing subgroup analysis. Due to the increasing role of large-scale databases, enhanced adherence to reporting guidelines may advance PS research.

Citrobacter koseri Surgical Site Infection after Femoropopliteal Vein Bypass for Popliteal Artery Aneurysm Treated with a Graft Preserving Strategy.

Background: A 69-year-old man underwent ligation and evacuation of a popliteal artery aneurysm with a femoral-to-popliteal vein bypass. He had a history of Citrobacter koseri prostatitis two months prior to the surgery. One month postoperatively, he presented with extremity swelling, redness, and fluid collections around the graft. Methods: A graft preserving strategy was adopted. The patient underwent operative drainage, washing, and received long-term antibiotic therapy. Fluid culture grew Citrobacter koseri, previously not reported as cause of surgical site infection with infrainguinal graft involvement. Results: The infection was treated successfully, and the patient is remains symptom free 18 months post-operatively. Conclusions: This case highlights the importance of considering culturing the aneurysm content in the presence of infectious history.

Landscape of interventional clinical trials involving gastrectomy for gastric cancer.

BACKGROUND: Gastric cancer (GC) is the third most common cause of malignancy associated mortality globally. The cornerstone of curative treatment involves surgical gastrectomy. In this study, we explore clinical trials involving gastrectomy for GC, highlighting inadequacies and underlining promising surgical interventions and strategies. MATERIALS AND METHODS: On 1 May 2020, ClinicalTrials.gov was explored for interventional trials related to gastrectomy for GC, without adding limitations for location or date. All data pertaining to the trials were collected. Characteristics such as phase, duration, enrolment size, location, treatment allocation, masking and primary endpoint were analysed. RESULTS: One hundred thirty-eight clinical trials met the search criteria. Clinical trials were performed in only 14 countries; most of them occurring in China. Most trials (33%) were still in the recruiting phase. On average, the length of trials was 3.9 years. Most trials had parallel assignment, were randomised and masked. The primary endpoint which was mostly commonly studied was overall survival (33%). The most common intervention studied is laparoscopic gastrectomy in 43 (31%) trials. CONCLUSIONS: Our study exposed a small number of trials, publication rate, absence of geographic variety in clinical trials involving gastrectomy for GC. Adequate management of trial design can help decrease duration and increase validity of results. More trials comparing different surgical techniques are needed to update the surgical practice of gastrectomy for GC.

Physical trauma and injury: A multi-center study comparing local residents and refugees in Lebanon.

BACKGROUND: Refugees are susceptible to various types of injury mechanisms associated with their dire living conditions and settlements. This study aims to compare and characterize the emergency department admissions due to physical trauma and injuries among local residents and refugees in greater Beirut. METHODS: This epidemiological study analyzes injury incidence and characteristics of patients presenting to Emergency Departments of 5 sentinel hospitals between 2017 and 2019. Using the WHO Injury Surveillance Guidelines and Pan-Asia Trauma Outcomes Study form, an injury data surveillance form was designed and used in hospital settings to collect data on injuries. Chi-square test analysis was performed to compare differences in injury characteristics between local residents and refugees. Regression models were constructed to assess the effect of being a refugee on the characteristics of injuries and outcomes of interest. RESULTS: A total of 4847 injuries (3933 local residents and 914 refugees) were reported. 87.4% of the total injuries among refugees were sustained by the younger age groups 0-45 years compared to 68.8% among local residents. The most prevalent injury mechanism was fall (39.4%) for locals and road traffic injury (31.5%) for refugees. The most injured body part was extremities for both populations (78.2% and 80.1%). Injuries mostly occurred at home or its vicinity (garden or inside the camp) for both populations (29.3% and 23.1%). Refugees sustained a higher proportion of injuries at work (6%) compared to locals (1.3%). On multivariate analysis, refugee status was associated with higher odds of having an injury due to a stab/gunshot (odds ratio (OR) = 3.392, 95% confidence interval (CI) = 2.605-4.416), having a concussion injury (OR = 1.718, 95% CI = 1.151-2.565), and being injured at work (OR = 4.147, 95% CI = 2.74-6.278). Refugee status was associated with increased odds of leaving the hospital with injury-related disability (OR = 2.271, 95% CI = 1.891-2.728)]. CONCLUSIONS: Injury remains a major public health problem among resident and refugee communities in Beirut, Lebanon. Refugees face several injury-related vulnerabilities, which adversely affect their treatment outcomes and long-term disabilities. The high prevalence of occupational and violence-related injuries among refugees necessitates the introduction of targeted occupational safety and financial security interventions, aiming at reducing injuries while enhancing social justice among residents.

A large number of COVID-19 interventional clinical trials were registered soon after the pandemic onset: a descriptive analysis.

BACKGROUND AND OBJECTIVE: There is a pressing need for evidence-based interventions to address the devastating clinical and public health effects of the coronavirus disease 2019 (COVID-19) pandemic. The number of registered trials related to COVID-19 is increasing by the day. The objective of this study was to describe the characteristics of the currently registered interventional clinical trials related to COVID-19. METHODS: We searched the World Health Organization's International Clinical Trials Registry Platform on May 15th, 2020. We included any entry that is related to COVID-19. We abstracted and then descriptively analyzed the following characteristics of the registered trials: study design, status, phase, primary endpoints, experimental interventions, and geographic location among other qualifiers. RESULTS: We identified 1,308 eligible registered trials. Most trials were registered with ClinicalTrials.gov (n = 703; 53.7%) and the Chinese Clinical Trial Registry (n = 291; 22.2%). The number of participants to be enrolled across these trials was 734,657, with a median of 110 participants per trial. The most commonly studied intervention category was pharmacologic (n = 763; 58.3%), with antiparasitic medications being the most common subcategory. Although over half of the trials were already recruiting, we identified published peer-reviewed results for only 8 of those trials. CONCLUSION: There is a relatively large number of registered trials but with very few results published so far. Although our findings suggest an appropriate initial response by the research community, the real challenge will be to get these trials completed, published, and translated into practice and policy.
