Unmasking the Underlying Causes: A Cross-Sectional Analysis of Mortality From Intentional and Unintentional Injuries in the United Arab Emirates

The United Arab Emirates (UAE) has experienced substantial development in infrastructure and transportation in the last few decades. Although available evidence suggests that the incidence of injuries has considerably increased in the previous few years, there is a scarcity of literature that comprehensively analyzed the mortality due to different types of injuries in the UAE. Therefore, the current study was designed to report mortality due to various intentional and unintentional injuries in the UAE. Secondary data was obtained from the World Health Organization (WHO) mortality database. We targeted injuries-specific mortality datasets. We applied a filter (UAE) to retrieve mortality data from unintentional and intentional injuries in the UAE. The latest data in the WHO mortality database was for 2020-21. A total of 10,357 death records from the UAE were present in the WHO mortality database. The percentage of injury-specific deaths out of total deaths was 8.69% (n=900). Injury-specific mortality rate per 100,000 population was 9.09. The percentage of injury-specific deaths was higher for males (87.3%, n=786) and the age group 25-34 years (n=323, 35.9%). Of the 900 injury-specific deaths, 449 (49.9%) were due to unintentional injuries, 216 (24.0%) were due to unintentional injuries, while the remaining (26.1%, n=235) deaths occurred due to Ill-defined injuries. More than half (53.7%, n=241) of unintentional injuries were because of road traffic injuries (RTIs) followed by fall (14.7%, n=66), exposure to mechanical forces (6.5%, n=29), drowning (6.0%, n=27) fire (1.1%, n=5), poisonings (1.1%, n=5), natural disasters (n=1, 0.2%) and other unintentional injuries (16.7%, n=75). More than three-quarters (83.3%, n=180) of intentional injuries were because of self-inflicted injuries while the remaining (16.7%, n=36) intentional injuries-specific deaths occurred due to violence. Many deaths in the UAE occur due to unintentional and intentional injuries. RTIs and falls are the leading causes of unintentional injury-specific deaths, while self-inflicted injuries and violence are the leading causes of intentional injury-specific deaths.

Low-Molecular-Weight Heparin Versus Warfarin in Adult Cancer Patients as a Precision Medicine for Thrombosis: A Systematic Review and Meta-Analysis

Venous thromboembolism (VTE) is a condition often seen in patients diagnosed with cancer and is recognized as a predictor of poor outcomes in these patients. The probability of VTE recurring is generally higher in people with cancer than in those without; hence, addressing this issue is essential when making healthcare decisions. Therefore, our systematic review was primarily designed to compare low-weight- molecular heparin (LMWH) to warfarin in reducing recurrent VTE among cancer patients. However, other outcomes were also evaluated, such as mortality and bleeding events observed more in cancer patients. The selection of relevant articles was carried out using a database search and a manual search, which involved reviewing reference lists of articles eligible for inclusion in the current review. The methodological quality of each included study was then assessed using Cochrane's risk of bias tool in the Review Manager software (RevMan 5.4.1). Additionally, pooled results were examined using the Review Manager software and presented as forest plots. Our search of electronic databases elicited a total of 2163 articles, of which only six were deemed eligible for inclusion and analysis. Data pooled from the six studies demonstrated the effectiveness of LMWH in minimizing the reoccurrence of VTE over warfarin [risk ratio (RR): 0.67; 95% CI: 0.47 - 0.95; p = 0.03]. However, LMWH had a similar effect statistically as warfarin on the major bleeding events (RR: 1.05; 95% CI: 0.62 - 1.77; p = 0.85), minor bleeding events (RR: 0.80; 95% CI: 0.54 - 1.20; p = 0.28), and all-cause mortality (RR: 1.00; 95% CI: 0.88 - 1.13; p = 0.99). While LMWH demonstrated its effectiveness in minimizing the incidence of VTE recurrence over warfarin in cancer patients, it had no statistical difference in terms of mortality or bleeding events when compared to warfarin. Based on our findings, we recommend that LMWH continues to be used as a first-line treatment regimen to mitigate recurrent VTE in cancer patients.

Plasma exchange (PE) versus intravenous immunoglobulin (IVIG) for the treatment of Guillain-Barré syndrome (GBS) in patients with severe symptoms: A systematic review and meta-analysis

Background and purpose

Guillain- Barré syndrome (GBS) is a neuropathic condition that leads to the rapid development of impairments and is characterized by weakness and numbness or tingling sensation in the legs and arms and sometimes loss of movement and feeling in the legs, arms, upper body, and face. Currently, the cure for the disease is yet to be developed. However, treatment options such as intravenous immunoglobulin (IVIG) and plasma exchange (PE) have been used to minimize the symptoms and duration of the disease. Therefore, this systematic review and meta-analysis compared the efficacy of IVIG and PE in treating GBS patients with severe symptoms.

Methodology

Six electronic databases, including PubMed, Embase, Scopus, ScienceDirect, Medline, and Google scholar, were scoured for articles related and relevant to our research. Additionally, more studies were obtained through the reference lists of the studies retrieved from these electronic databases. Quality assessment and statistical data analysis were conducted using Review Manager software (RevMan 5.4.1).

Results

The search for relevant articles resulted in 3253 articles, of which only 20 were included for review in the current study. A sub-group analysis indicated no significant difference in the curative effect (Hughes score reduces by at least one score 4 weeks after GBS treatment; OR: 1.00; 95% CI: 0.66-1.52; p = 1.00 and Achieving grade 0 or 1 on Hughes scale; OR: 1.03; 95% CI: 0.27-3.94; p = 0.97). Similarly, the statistical showed that the difference in length of hospitalization and duration of mechanical ventilation was insignificant between the IVIG and PE group (Standard Mean Difference (SMD): -0.45; 95% CI: -0.92, 0.02; I² = 91%; p = 0.06 and SMD: -0.54; 95% CI: -1.67, 0.59; I² = 93%; p = 0.35, respectively). Moreover, the meta-analysis did not find any significant difference in the risk of GBS relapse (RR: 0.47; 95% CI: 0.20-1.14; p = 0.10) and risk of complications related to the treatment regimens (RR: 1.03; 95% CI: 0.71-1.48; p = 0.89). However, the statistical analysis of outcomes from 3 studies showed that the risk of discontinuation was significantly lower in the IVIG group than in the PE group (RR: 0.22; 95% CI: 0.06-0.88; p = 0.03).

Conclusion

Our study suggests that IVIG and PE have similar curative effects. Similarly, IVIG seems easier to use and thus can be preferred for treating GBS.

A Systematic Review and Meta-Analysis of Randomized Controlled Trials Comparing the Effects of Biguanides (Metformin) and Thiazolidinediones on Glucose Tolerance and Insulin Sensitivity in Patients With Type II Diabetes Mellitus

Type II diabetes mellitus (T2DM) is a global epidemic affecting people of all ages in developed and developing countries. The disease is usually characterized by insulin resistance and glucose intolerance; therefore, oral antidiabetic drugs such as thiazolidinediones (TZDs) and biguanide metformin are used to counter these defects. Due to the varied action mechanisms of TZDs and Metformin, their effects on insulin sensitivity and glucose tolerance may differ. Therefore, the current study was carried out to compare the effects of Metformin and TZDs on insulin sensitivity and glucose tolerance among patients with T2DM. Two methods, including using a well-outlined search strategy in 5 electronic databases including ScienceDirect, Google Scholar, PubMed, Scopus, and Embase, and a manual search which involved going through the reference lists of studies from the electronic databases were used to retrieve studies published between 2000 and 2022. Additionally, data analysis of outcomes retrieved from the studies eligible for inclusion and the methodological quality was carried out using the Review Manager software (RevMan 5.4.1) and STATA. The meta-analysis has shown that TZDs have a significantly better overall effect on fasting plasma glucose (FPG) (SMD:0.61; 95% CI:0.06, 1.16: p = 0.03) and insulin sensitivity than Metformin (Mean QUICKI: 0.306 ± 0.019 vs. 0.316 ± 0.019, respectively; p=0.0003). However, the TZDs and Metformin offer the same effect on glycemic control as assessed using HBA1c levels (MD: 0.10; 95% CI: -0.20, 0.40; p = 0.52). TZDs offer better insulin sensitivity and glucose tolerance improvements compared to Metformin. This evidence contradicts the current guidelines by the American Diabetes Association/European Association for the Study of Diabetes (ADA/EASD) and the American Association of Clinical Endocrinologists/American College of Endocrinology (AACE/ACE), which recommend the use of Metformin as the first-line drug monotherapy for patients with T2DM.

Acute Calculous Cholecystitis With Sinus Bradycardia: Cope's Sign Encountered

Acute cholecystitis and cardiac ischemia can have a similar clinical presentation in some patients. Nonspecific electrocardiographic changes and arrhythmias can occur in acute cholecystitis and gallbladder disease that can confuse the treating physician leading to extensive cardiac workup. Emergency physicians and cardiologists should be aware of these changes so they can expedite the management of acute cholecystitis, which can lead to the resolution of these changes. We report a case of a 53-year-old male who presented with diffuse abdominal pain, nausea, and vomiting. His ECG showed sinus bradycardia. Imaging confirmed the diagnosis of acute calculous cholecystitis. His cardiac workup was unremarkable. His sinus bradycardia was resolved with the management of acute cholecystitis. This case highlights the possibility of a "cardio-biliary reflex" that is initiated by gallbladder pain via autonomic vagal innervation.
