Khat use: History and heart failure

Recent reports suggest that 20 million people worldwide are regularly using khat as a stimulant, even though the habit of chewing khat is known to cause serious health issues. Historical evidence suggests khat use has existed since the 13th century in Ethiopia and the southwestern Arabian regions even before the cultivation and use of coffee. In the past three decades, its availability and use spread all over the world including the United States and Europe. Most of the consumers in the Western world are immigrant groups from Eastern Africa or the Middle East. The global transport and availability of khat has been enhanced by the development of synthetic forms of its active component. The World Health Organization considers khat a drug of abuse since it causes a range of health problems. However, it remains lawful in some countries. Khat use has long been a part of Yemeni culture and is used in virtually every social occasion. The main component of khat is cathinone, which is structurally and functionally similar to amphetamine and cocaine. Several studies have demonstrated that khat chewing has unfavorable cardiovascular effects. The effect on the myocardium could be explained by its effect on the heart rate, blood pressure, its vasomotor effect on the coronary vessels, and its amphetamine-like effects. However, its direct effect on the myocardium needs further elaboration. To date, there are few articles that contribute death among khat chewers to khat-induced heart failure. Further studies are needed to address the risk factors in khat chewers that may explain khat-induced cardiotoxicity, cardiomyopathy, and heart failure.

Epidemiology of occupational injuries by nationality in Qatar: Evidence for focused occupational safety programmes

INTRODUCTION Occupational injuries are the second leading cause of trauma admission in Qatar. Given the wide diversity of the countrys migrant worker populations at risk, this study aimed to analyse and describe the epidemiology of these injuries based on the workers nationality residing in Qatar. METHODS A retrospective analysis of trauma registry data on occupational-related injuries was conducted. The analysis included all patients [aged ≥18 years] admitted to the Level I Hamad Trauma Center, from January 1, 2010 to December 31, 2013. RESULTS Out of 6555 trauma admissions, 2015 (30.7%) patients had occupational injury. The admitted Case Fatality Rate (CFR) was 4.3 per 100 occupational injury related trauma admissions. Overall non-fatal occupational injury rate was 37.34 per 100,000 workers, whereas fatal injury rate was 1.58 per 100,000 workers. Most of the workers experiencing occupational injuries were from Nepal (28%), India (20%) and Bangladesh (9%). Fatal occupational injuries were predominately among Indians (20%), Nepalese (19%), and Filipinos/Bangladeshis (both 8%). Filipinos had the highest admitted CFR at 8.2 deaths per 100 trauma admissions with the next highest being Indians and Indonesians (4.2 per 100 trauma admissions). During the study period, the incidence of severe occupational injuries decreased despite a simultaneous increase in the worker population within Qatar. Almost one in four occupational injuries was a major trauma (ISS≥16). Nepalese and Indian workers represented 29% and 18% of all major trauma cases. CONCLUSIONS Non-fatal occupational injuries appear to follow a pattern distinct from fatal ones. High-risk worker populations as defined by those with high admitted CFRs, experiencing the most severe or fatal injuries, must be the focus of targeted risk factor analysis and occupational safety interventions.

Incidence, Demographics, and Outcome of Traumatic Brain Injury in The Middle East: A Systematic Review

BACKGROUND Traumatic brain injury (TBI) is a serious global public health challenge. We aimed to assess the pattern of TBI in the Middle East, as reported in the last decade. METHODS Literature searches were conducted on PubMed, MEDLINE, and Google scholar electronic databases. The search terms used in different combinations were epidemiology, incidence, case fatality, mortality, intracranial injury, brain injury, head injury, and the country names. Additional searches were conducted using reference lists of studies and review articles for selection of relevant articles. The search yielded 1082 articles; of which 701 duplicates and 346 articles were excluded. Thirty-five original studies met the inclusion criteria. Data were extracted using standardized Excel form and pilot tested. Median with interquartile range (IQR) was used to estimate the incidence rate and mortality of TBI. RESULTS In the Middle East region, the median TBI incidence rate per capita was 45 (IQR, 38.5-367) per 100,000. The overall median emergency department-based TBI mortality, which included all age groups and all injury severities, was 10% (IQR, 7.75-15.75). We estimated the overall median mortality for head trauma studies based on emergency department admissions as 6% (IQR, 3-18) among all age groups and all injury severities. The overall TBI-related median mortality in the intensive care unit-based studies was 25% (IQR, 15.5-47). CONCLUSIONS The epidemiology of TBI in the Middle East remains understudied. The use of a globally recognized definition of TBI will contribute greatly to improve its reporting, analysis, and interpretation and to establish appropriate injury prevention programs.

Occupational injuries in workers from different ethnicities.

Objectives: Occupational injuries remain an important unresolved issue in many of the developing and developed countries. We aimed to outline the causes, characteristics, measures and impact of occupational injuries among different ethnicities. Materials and Methods: We reviewed the literatures using PUBMED, MEDLINE, Google Scholar and EMBASE search engine using words: “Occupational injuries” and “workplace” between 1984 and 2014. Results: Incidence of fatal occupational injuries decreased over time in many countries. However, it increased in the migrant, foreign born and ethnic minority workers in certain high risk industries. Disproportionate representations of those groups in different industries resulted in wide range of fatality rates. Conclusions: Overrepresentation of migrant workers, foreign born and ethnic minorities in high risk and unskilled occupations warrants effective safety training programs and enforcement of laws to assure safe workplaces. The burden of occupational injuries at the individual and community levels urges the development and implementation of effective preventive programs.

Risk Stratification of Necrotizing Fasciitis Based on the Initial Procalcitonin Concentration: A Single Center Observational Study

BACKGROUND Necrotizing fasciitis (NF) is a potentially fatal subcutaneous tissue and fascia infection. We studied the role of serum procalcitonin in the identification and assessment of severity of sepsis in patients with NF. METHODS A retrospective analysis was conducted from January 2000 to December 2013 for all patients who admitted to surgical intensive care with provisional diagnosis of NF. Patients were categorized into four groups based on the initial procalcitonin concentrations (Group I: <0.5 low risk, Group II: ≥0.5-<2 moderate risk, Group III: ≥2-<10 high risk, and Group IV: ≥10 ng/mL high likelihood of severe sepsis). RESULTS During the study period, 331 cases were identified to have NF with a mean age of 51 ± 14 years. Serum procalcitonin was tested in 62 cases (only between 2011 and December 2013) and all were positive (Group I: 22%, Group II: 18%, Group III: 21%, and Group IV: 39%). The most common affected regions were thigh and chest in Group II (46% and 9%, respectively), lower limbs in Group III (46%), and perineum and abdomen in Group IV (25% and 21%, respectively). In the four groups, 21 patients developed septic shock (Group I: 0%, Group II: 14%, Group III: 24%, and Group IV: 62%). The cut off procalcitonin value for septic shock was 5.6 ng/mL. Using receiver-operating characteristic curve, this cut off with the Area under the Curve (AUC) of 0.77 was found to have sensitivity 81% and specificity 67%. Sequential Organ Failure Assessment (SOFA) score was substantially greater in Group III and Group IV in comparison to Group I and Group II, p = 0.006. Procalcitonin levels were correlated well with SOFA score (r = 0.34, p = 0.007). There were 17 deaths in the four groups (Group I: 6%, Group II: 23%, Group III: 12%, and Group IV: 59%). CONCLUSION Initial procalcitonin concentration in NF carries an important prognostic value and it correlates well with SOFA score and can predict the development of septic shock early in patients with NF.

Traumatic injuries in patients with diabetes mellitus

Diabetes mellitus (DM) is associated with increased in-hospital morbidity and mortality in patients sustained traumatic injuries. Identification of risk factors of traumatic injuries that lead to hospital admissions and death in DM patients is crucial to set effective preventive strategies. We aimed to conduct a traditional narrative literature review to describe the role of hypoglycemia as a risk factor of driving and fall-related traumatic injuries. DM poses significant burden as a risk factor and predictor of worse outcomes in traumatic injuries. Although there is no consensus on the impact and clear hazards of hyperglycemia in comparison to the hypoglycemia, both extremes of DM need to be carefully addressed and taken into consideration for proper management. Moreover, physicians, patients, and concerned authorities should be aware of all these potential hazards to share and establish the right management plans.

Alcohol Screening in a National Referral Hospital: An Observational Study from Qatar

Background Alcohol consumption is a high-risk factor for several medical disorders and traffic accidents and poses a burden on outpatient clinics and emergency units. We aimed to assess the pattern of alcohol screening among patients in a multicultural setting in a national referral hospital in an Arab Middle-Eastern country. Material/Methods A retrospective analysis was conducted for patients who were screened with blood alcohol concentration (BAC) in the Emergency Department (ED) in the period from January 2009 to December 2012. BAC positive and negative patients were compared, and BAC positive patients were classified into mmol/L (Group 1: BAC 0.1–10.8 (less intoxicated); Group 2: BAC 10.9–21.7 (intoxicated), and Group 3: >21.7 mmol/L (intoxicated at CNS depression level). Results A total of 9417 patient visits were screened for BAC during the study period (an average of 4.87 per 1000 ED visits); 38% of these tested positive. Most screened persons were males (97%) with a mean age of 37.5±11.6 years. There was a steady increase in BAC screening initially (3.18 per 1000 ED visits in 2009 and 7.47 in 2012). However, the proportion of BAC-positives per total screened decreased steadily over the years, from 50% in 2008 to 33% in 2012. There were more BAC positives (92% vs. 81%, p<0.05) in patients seeking medical vs. non-medical assessment. Among BAC positives, Group 3 patients had higher HLOS (p=0.001), but the ICU-LOS was comparable. Conclusions Despite the absence of a clinical protocol for alcohol screening, this study shows that alcohol consumption has a serious impact in ED visits and hospitalizations, even in a country that partially prohibits alcohol drinking. Implementing a protocol for the screening of alcohol misuse among select hospitalized patients should be considered in the ED.
