The Prevalence of Burnout and Its Associated Factors Among Surgical Specialists in Kuwait Ministry of Health Hospitals.

BACKGROUND: Workplace burnout is a state of emotional exhaustion (EE), depersonalization of others (DP), and low personal accomplishment (PA) owing to workplace stressors. This study aimed to assess the prevalence of burnout and its associated factors among surgical specialists in Kuwait. METHODS: This cross-sectional study assessed the prevalence of burnout among 489 surgeons in practice at Kuwait Ministry of Health (MOH). Data were collected using a self-administered questionnaire. Burnout was assessed using the Maslach Burnout Inventory, which defines burnout as having a high score of EE or DP, or a low score of PA; with severe burnout involving all. The associations between burnout or severe burnout with sociodemographic and occupational characteristics were assessed using multivariate binary logistic regression to adjust for potential confounders. RESULTS: Prevalence estimates for burnout and severe burnout were 76.9% (95% Confidence Interval = 72.9-80.7%) and 14.0% (11.0-17.5%), respectively. The prevalence estimates for high EE, high DP, and low PA scores were 44.7, 43.1, and 47.2%, respectively. The prevalence of burnout and severe burnout was highest among neurosurgeons. Burnout was lowest among otolaryngology surgeons and severe burnout was lowest among cardiothoracic surgeons. After adjustment, burnout was associated with younger age, lower income, and more on-calls per month. The four most common sources of stress included less family time, verbal assault, case overload, and highly complicated cases. CONCLUSION: The prevalence of burnout among surgeons in Kuwait MOH hospitals is high. Occupational health programs should use these findings to design and implement interventions that can treat and prevent burnout in this population.

Modeling the effect of lockdown timing as a COVID-19 control measure in countries with differing social contacts.

The application, timing, and duration of lockdown strategies during a pandemic remain poorly quantified with regards to expected public health outcomes. Previous projection models have reached conflicting conclusions about the effect of complete lockdowns on COVID-19 outcomes. We developed a stochastic continuous-time Markov chain (CTMC) model with eight states including the environment (SEAMHQRD-V), and derived a formula for the basic reproduction number, R0, for that model. Applying the [Formula: see text] formula as a function in previously-published social contact matrices from 152 countries, we produced the distribution and four categories of possible [Formula: see text] for the 152 countries and chose one country from each quarter as a representative for four social contact categories (Canada, China, Mexico, and Niger). The model was then used to predict the effects of lockdown timing in those four categories through the representative countries. The analysis for the effect of a lockdown was performed without the influence of the other control measures, like social distancing and mask wearing, to quantify its absolute effect. Hypothetical lockdown timing was shown to be the critical parameter in ameliorating pandemic peak incidence. More importantly, we found that well-timed lockdowns can split the peak of hospitalizations into two smaller distant peaks while extending the overall pandemic duration. The timing of lockdowns reveals that a "tunneling" effect on incidence can be achieved to bypass the peak and prevent pandemic caseloads from exceeding hospital capacity.

Prevalence of smoking in the Kuwaiti adult population in 2014: a cross-sectional study.

The study objective was to assess tobacco smoking prevalence in Kuwaiti adults in relation to sociodemographic characteristics. A cross-sectional study survey was conducted in 2014 on 3917 Kuwaiti citizens (18-69 years) following the World Health Organization (WHO) STEPwise Approach to Surveillance (STEPS) methodology. The study assessed prevalence of self-reported ever-smoking or currently smoking tobacco products and exposure to secondhand smoke in relation to demographic and smoking-related characteristics. The prevalence of "ever smoker" in men and women was 49.9% and 4.4%, respectively, whereas the prevalence of "current smoker" was 39.2% and 3.3%, respectively. Sex (adjusted OR [AOR], 19.2 [95% confidence interval (CI) 13.0-28.3], male versus female) was significantly associated with current smoking. Among daily smokers, 87.1% used manufactured cigarettes. The average daily number of manufactured cigarettes for men and women was 21.8 and 13.0, respectively. Mean age at smoking initiation was 17.5 years (95% CI 17.2-17.9). The prevalence of secondhand smoke at home and work was 38.6% and 29.9%, respectively. Half of Kuwaiti men have smoked at some point in their life with most of these being current smokers. Secondhand smoke is a common exposure at home and work, posing serious health risks to the population.

SARS-CoV-2 Serosurvey in Addis Ababa, Ethiopia.

In a serosurvey of asymptomatic people from the general population recruited from a clinical laboratory in May 2020 in Addis Ababa, Ethiopia, three of 99 persons tested positive for SARS-CoV-2 IgG (3.0%, 95% binomial exact confidence interval: 0.6-8.6%). Taking into account pretest probability and the sampling scheme, the range of plausible population prevalence values was approximately 1.0-8.4%. These results suggest that a larger number of people have been infected than the counts detected by surveillance to date; nevertheless, the results suggest the large majority of the general population in Addis Ababa currently is susceptible to COVID-19.

Glycemic control in Kuwaiti diabetes patients treated with glucose-lowering medication.

BACKGROUND: Diabetes is prevalent in Kuwait. We aimed to assess the level of glycemic control in Kuwaiti adults with diabetes. METHODS: The World Health Organization's STEPS non-communicable disease risk factor survey was conducted in Kuwait in 2014. Participants' demographics, medical history, physical measurements and blood biochemistry were assessed. A total of 2561 Kuwaiti men and women aged 18-69 years completed all three survey steps. Glycemic control in 278 individuals with diabetes who were on glucose-lowering medication was determined using the US National Institutes of Health guidelines of fasting plasma glucose (FPG) ≤7.2mmol/l and the American Diabetes Association guidelines of glycated hemoglobin (HbA1c) <7% (53mmol/mol). RESULTS: Adequate glycemic control in people with drug-treated diabetes was 34.5% when determined by HbA1c, 37.8% when determined by FPG level, and 24.5% when both criteria were met. Mean body-mass index and fasting serum triglycerides were significantly higher and serum high-density lipoprotein-cholesterol significantly lower in individuals with an inadequate glycemic control than in those with adequate control. Women with diabetes were almost twice as likely to have inadequate HbA1c levels as men with diabetes (OR, 1.9, [95% CI, 1.03, 3.5]). CONCLUSIONS: Glycemic control in Kuwaiti adults with treated diabetes is low. A systemic, multi-disciplinary public health approach is needed to improve diabetes education and adherence to treatment.

The Prevalence of Overweight and Obesity in an Adult Kuwaiti Population in 2014.

Background: According to World Health Organization (WHO) estimates, Kuwait is ranked amongst the top countries in the world in obesity prevalence. This study aims to describe the prevalence of overweight, obesity, and various types of adiposity in Kuwaiti adults. Methods: This cross-sectional study of 3,915 Kuwaiti adults aged 18-69 years used the STEP-wise approach to surveillance of non-communicable diseases, a WHO Instrument for Chronic Disease Risk Factor Surveillance. We assessed demographic information, lifestyle, personal and family history of diseases and physical measurements (height, weight, waist, and hip circumferences). All participants with valid height and weight measurements (n = 3,589) were included in the present analysis. Overweight was defined as BMI 25-29.9 kg/m2 and obesity as BMI ≥30 kg/m2. Results: Obesity prevalence was 40.3% [95% confidence interval, 38.6-42.0%] (men, 36.5%; women, 44.0%); and overweight prevalence was 37% [35.4-38.7%] (men, 42%; women, 32.1%). The median BMI was 28.4 kg/m2 among men and 29.1 kg/m2 among women. Obesity prevalence was directly associated with female sex, age, history of diabetes, and being married in both men and women; and was inversely associated with education level in women. The prevalence of elevated waist-to-hip ratio was 46.9% among men and 37.9% among women. Waist circumference, waist-hip and waist-height ratios were directly associated with diabetes in both men and women, and inversely associated with education level in women. Conclusion: Almost eight in ten Kuwaiti adults were overweight or obese. Urgent public health action is warranted to tackle the obesity epidemic in Kuwait.

The prevalence of pre-diabetes and diabetes in the Kuwaiti adult population in 2014.

BACKGROUND: Kuwait ranks among the top 20 countries worldwide in diabetes prevalence. This study's objectives were to assess the prevalence of pre-diabetes and diabetes in Kuwaiti adults. METHODS: Kuwaiti citizens aged 18-69 years (n = 3915) were studied using the WHO's STEPwise survey methodology, including its Instrument for Chronic Disease Risk Factor Surveillance. Participants' demographics, medical history, physical measurements and blood biochemistry were assessed. A subset of 2561 individuals completed all three survey steps, including fasting plasma glucose (FPG) and HbA1c assays. The study assessed the prevalence of pre-diabetes (FPG 6.1-6.9 mmol/L or HbA1c level 5.7-6.4%) and diabetes (self-reported history of diabetes with prescription of diabetes medications or FPG ≥ 7 mmol/L or HbA1c level ≥6.5%). RESULTS: The prevalence of pre-diabetes was 19.4% [95% CI: 17.9-21.0%] (By sex: Men, 19.3%; Women, 19.5%; p = 0.92; By age (years): 18-29 y, 13.9%; 30-44 y, 22.6%; 45-59 y, 25.8%; 60-69 y, 16.4%; p < 0.001). The prevalence of diabetes was 18.8% [17.3-20.4%] (By sex: Men, 20.4%; Women, 17.4%; p = 0.055; By age: 18-29 y, 6.6%; 30-44 y, 14.0%; 45-59 y, 36.7%; 60-69 y, 62.8%; p < 0.001), of whom 41.5% were previously undiagnosed. Diabetes prevalence was 27.4% among those with body mass index (BMI) ≥ 30 kg/m2, 29% among those with elevated waist-hip ratio and 36% among those with hypertension. Diabetes was positively associated with BMI, waist-hip ratio and blood pressure level. Pre-diabetes was positively associated with BMI and waist-hip ratio, but not blood pressure level. CONCLUSIONS: Almost 40% of Kuwaiti citizens had pre-diabetes or diabetes. Urgent public health action is needed to decrease diabetes prevalence and thus avoid associated morbidity and mortality.

Hyperuricemia after orthotopic liver transplantation: divergent associations with progression of renal disease, incident end-stage renal disease, and mortality.

BACKGROUND: Although hyperuricemia is common after orthotopic liver transplantation (OLT), its relationship to mortality, progressive kidney disease, or the development of end stage renal disease (ESRD) is not well-described. METHODS: Data from 304 patients undergoing OLT between 1996 and 2010 were used to assess the association of mean serum uric acid (UA) level in the 3-months post-OLT with mortality, doubling of creatinine, and ESRD incidence. Post-OLT survival to event outcomes according to UA level and eGFR was assessed using the Kaplan Meier method and multivariate Cox proportional hazards models. RESULTS: Mean UA level among the 204 patients with an eGFR level ≥60 ml/min/1.73 m2 was 6.4 mg/dl compared to 7.9 mg/dl among the 100 patients with eGFR <60 (p < 0.0001). During a median of 4.6 years of follow-up, mortality rate, doubling of creatinine, and ESRD incidence were 48.9, 278.2, and 20.7 per 1000 person-years, respectively. In the first 5 years of follow-up, elevated UA was associated with mortality (Hazard Ratio, HR = 1.7; p = 0.045). However, among those with eGFR ≥ 60, UA level did not predict mortality (HR = 1.0; p = 0.95), and among those with eGFR < 60, elevated UA was a strong predictor of mortality (HR = 3.7[1.1, 12.0]; p = 0.03). UA was not associated with ESRD, but was associated with doubling of creatinine among diabetics (HR = 2.2[1.1, 4.3]; p = 0.025). CONCLUSION: In this post-OLT cohort, hyperuricemia independently predicted mortality, particularly among patients with eGFR < 60, and predicted doubling of creatinine among diabetics.

Patterns of Kidney Function Before and After Orthotopic Liver Transplant: Associations With Length of Hospital Stay, Progression to End-Stage Renal Disease, and Mortality.

BACKGROUND: In the context of orthotopic liver transplantation (OLT), renal dysfunction is used as a criterion for simultaneous liver-kidney transplantation. Changes in glomerular filtration rate (GFR) the year before and after OLT have not been well defined. METHODS: In a cohort of 416 OLT patients from 1996 to 2009, estimated GFR (eGFR) was assessed during the 12 months before OLT (period A), at time of OLT (period B), and the 12 months after OLT (period C). Outcomes included progression to end stage renal disease (ESRD), length of stay, and mortality. RESULTS: The overall rate of progression to ESRD over 15 years of follow-up was 0.155/person-year and was strongly associated with eGFR <60 (hazard ratio [HR] = 2.7; P < 0.001), diabetes (HR = 2.6; P < 0.001), and with a combination of the 2 (HR = 5.5; P < 0.0001). Mean eGFR decreased from period A (86 mL/min per 1.73 m) to period B (77; P < 0.001) to period C (71; P < 0.001), with similar decreases in eGFR across subgroups of clinical variables. Patients with eGFR less than 60 mL/min per 1.73 m at OLT had acute and large decreases in eGFR from periods A to B, then increases to period C. Length of stay was associated with eGFR at OLT, hepatorenal syndrome, dialysis requirement, model for end-stage liver disease score, and alcoholic liver disease. Twelve-month mortality was strongly associated with time-dependent change in eGFR, hepatorenal syndrome, dialysis requirement, hepatitis C, and model for end-stage liver disease era transplantation but was not associated with eGFR at OLT. CONCLUSIONS: Among OLT patients, renal function worsened in all subgroups from before to after OLT, but the association of progression to ESRD was particularly high among patients with both diabetes and eGFR less than 60 at the time of OLT. This suggests that diabetes could be considered as a criterion when making decisions regarding simultaneous liver-kidney transplantation.

Demography and clinical course of ulcerative colitis in Arabs - a study based on the Montreal classification.

OBJECTIVE: Ulcerative colitis (UC) is generally considered a disease of the Caucasian populations in developed countries, but its incidence is increasing rapidly in many developing countries, including the Middle East. The objective of this study was to determine the clinical epidemiology of UC in Arabs. MATERIAL AND METHODS: This cross-sectional medical record-based descriptive study collected sociodemographic and clinical information on 182 Arab patients with UC in Kuwait. Age at diagnosis, extent and severity of disease were determined according to the Montreal classification. results: Among the 182 patients, 91 (50.0%) were males. The median age at diagnosis was 28.5 years. Family history of UC was reported by 26 (14.3%) patients. The extent of the disease was limited to the rectum in 34 (18.7%) patients, left sided in 67 (36.8%) and pan colitis in 81 (44.5%). At the time of inclusion in the study, 127 (69.8%) patients were in clinical remission, 53 (29.1%) had mild-to-moderate disease and 2 (1.1%) had severe colitis. Younger age at diagnosis and non-smoking were associated with more extensive colitis. The majority of patients were treated with mesalamine, steroids and immunomodulators, while biologic therapy and surgery were needed in 5% and 4% of the patients, respectively. CONCLUSIONS: UC presents more commonly at younger age among Arabs in Kuwait. Extensive disease at presentation is associated with younger age at diagnosis and absence of tobacco smoking. There also appears to be less need for surgery and biologic therapy for the disease in this population.

Adherence to ACC/AHA performance measures for myocardial infarction in six Middle-Eastern countries: association with in-hospital mortality and clinical characteristics.

BACKGROUND/OBJECTIVES: This study assesses adherence to performance measures for acute myocardial infarction (AMI) in six Middle-Eastern countries, and its association with in-hospital mortality. Few studies have previously assessed these performance measures in the Middle East. METHODS: This cohort study followed 5813 patients with suspected AMI upon admission to discharge. Proportions of eligible participants receiving the following performance measures were calculated: medications within 24 hours of admission (aspirin and beta-blocker) and on discharge (aspirin, beta-blockers, angiotensin converting enzyme inhibitors [ACEI], and lipid-lowering therapy), reperfusion therapy, and low-density lipoprotein (LDL) cholesterol measurement. A composite adherence score was calculated. Associations between performance measures and clinical characteristics were assessed using multivariate logistic regression. RESULTS: Adherence was above 90% for aspirin, reperfusion, and lipid-lowering therapies; between 60% and 82% for beta-blockers, ACEI, statin therapy, time-to-balloon within 90 minutes, and LDL-cholesterol measurement; and 33% for time-to-needle within 30 minutes. After adjustment, factors associated with high composite performance score (>85%) included Asian ethnicity (Odds Ratio, OR=1.3; p=0.01) and history of hyperlipidemia (OR=1.4; p=0.001). Factors associated with a lower score included atypical symptoms (OR=0.6; p=0.003) and high GRACE score (OR=0.6; p<0.001). Lower in-hospital mortality was associated with provision of reperfusion therapy (OR=0.54, p=0.047) and beta-blockers within 24 hours (OR=0.33, p=0.005). CONCLUSIONS: Overall adherence was lowest among the highest-risk patients. Lower in-hospital mortality was independently associated with adherence to early performance measures, comprising observational evidence for their effectiveness in a Middle East cohort. These data provide a focus for regional quality improvement initiatives and research.

Physical accessibility and utilization of health services in Yemen.

BACKGROUND: Assessment of physical access to health services is extremely important for planning. Complex methods that incorporate data inputs from road networks and transport systems are used to assess physical access to healthcare in industrialised countries. However, such data inputs hardly exist in many developing countries. Straight-line distances between the service provider and resident population are easily obtained but their relationship with driving distance and travel time is unclear. This study aimed to investigate the relationship between different measures of physical access, including straight-line distances, road distances and travel time and the impact of these measures on the vaccination of children in Yemen. METHODS: Coordinates of houses and health facilities were determined by GPS machine in Urban and rural areas in Taiz province, Yemen. Road distances were measured by an odometer of a vehicle driven from participants' houses to the nearest health centre. Driving time was measured using a stop-watch. Data on children's vaccination were collected by personal interview and verified by inspecting vaccination cards. RESULTS: There was a strong correlation between straight-line distances, driving distances and driving time (straight line distances vs. driving distance r = 0.92, p < 0.001, straight line distances vs. driving time r = 0.75; p < 0.001, driving distance vs. driving time r = 0.83, p < 0.001). Each measure of physical accessibility showed strong association with vaccination of children after adjusting for socio-economic status. CONCLUSION: Straight-line distances, driving distances and driving time are strongly linked and associated with vaccination uptake. Straight-line distances can be used to assess physical access to health services where data inputs on road networks and transport are lacking. Impact of physical access is clear in Yemen, highlighting the need for efforts to target vaccination and other preventive healthcare measures to children who live away from health facilities.

Disease activity and cytokine production in mitogen-stimulated peripheral blood mononuclear cells from patients with rheumatoid arthritis.

OBJECTIVE: To test whether there are differences in the levels and ratios of 6 pro- and 3 anti-inflammatory cytokines produced by mitogen-stimulated peripheral blood mononuclear cells (PBMCs) in rheumatoid arthritis (RA) subjects compared to controls. SUBJECTS AND METHODS: 79 participants (42 seropositive RA patients and 37 healthy controls) were enrolled in this study. The production levels in mitogen-stimulated PBMCs of the 6 proinflammatory cytokines (IFN-gamma, TNF-alpha, TNF-beta, IL-8, IL-17, IL-18) and 3 anti-inflammatory cytokines (IL-4, IL-10, IL-13) were assayed by ELISA using kits obtained from Immunotech SA. The ratios of pro- to anti-inflammatory cytokines were calculated for all participants. RESULTS: There were significantly elevated levels of IL-8 and IL-10, and reduced levels of IFN-gamma, IL-4, and IL-17 in mitogen-stimulated PBMC culture supernatants of RA subjects compared to controls. Of the 18 pro-/anti-inflammatory cytokine ratios, 3 ratios (TNF-alpha/IL13, IL-8/IL-4 and IL-8/IL-13) were significantly higher in RA patients compared to controls; and 6 were higher in controls (IFN-gamma/IL-4; IFN-gamma/IL-10; IFN-gamma/IL-13; TNF-beta/IL10; IL-17/IL-10; IL-18/IL-10). CONCLUSIONS: Activated PBMCs of RA patients, regardless of disease activity, showed higher-level production of IL-8 and IL-10 compared to controls; lower-level production of IFN-gamma, IL-4, and IL-17; and elevated ratios of TNF-alpha/IL-13, IL-8/IL-4 and IL-8/IL-13.

Association of kidney function with serum lipoprotein(a) level: the third National Health and Nutrition Examination Survey (1991-1994).

BACKGROUND: Elevated lipoprotein(a) (Lp[a]) levels have been observed in patients on dialysis therapy. However, few studies explored the relationship between kidney function and Lp(a) levels in patients with mild to moderate chronic kidney disease. METHODS: We examined the association of estimated glomerular filtration rate (GFR) with Lp(a) level in 7,675 participants in the second phase of the Third National Health and Nutrition Examination Survey. RESULTS: There was no association between Lp(a) level and estimated GFR in the overall sample (geometric mean, 10.4 mg/dL [95% confidence interval (CI), 9.2 to 11.8] in the group with a GFR of 90 to 149 mL/min/1.73 m2 versus 9.3 mg/dL [95% CI, 7.9 to 11.0] in the group with a GFR of 60 to 89 mL/min/1.73 m2 versus 12.1 mg/dL [95% CI, 9.0 to 15.9] in the group with a GFR of 15 to 59 mL/min/1.73 m2; P = 0.77 for linear trend) or non-Hispanic whites (geometric mean, 8.9 mg/dL [95% CI, 7.8 to 10.2] versus 8.5 mg/dL [95% CI, 7.1 to 10.2] versus 10.9 mg/dL [95% CI, 8.1 to 14.7]; P = 0.54 for linear trend). However, non-Hispanic blacks (geometric mean, 30.4 mg/dL [95% CI, 28.0 to 33.0] versus 35.2 mg/dL [95% CI, 31.4 to 39.4] versus 40.2 mg/dL [95% CI, 27.7 to 58.2]; P = 0.01 for linear trend) and Mexican Americans (geometric mean, 6.2 mg/dL [95% CI, 5.3 to 7.2] versus 7.4 mg/dL [95% CI, 6.4 to 8.5] versus 11.0 mg/dL [95% CI, 5.7 to 20.3]; P = 0.04 for linear trend) showed modestly, but significantly, greater Lp(a) levels with lower GFRs. In a weighed quantile regression model adjusted for age, sex, and race, a lower GFR was associated with greater 95th percentile serum Lp(a) values in the overall sample and non-Hispanic whites and with greater median Lp(a) levels in Mexican Americans. CONCLUSION: In a cross-section of the US population, a low GFR is associated with only moderately greater Lp(a) levels, and this association may differ by race-ethnicity.
