RESUMEN

Higher coronary artery calcium (CAC) scores and progression of CAC are associated with higher mortality. We previously reported that subjects with coronary artery disease randomly allocated to eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) supplementation or none had similar significant increases in CAC score over 30 months. Whether these findings are influenced by diabetes status is unknown. A total of 242 subjects with coronary artery disease who were on statin therapy were randomly allocated to to 1.86 g EPA and 1.5 g DHA daily or none (control). The CAC score was measured at baseline and 30-month follow-up using noncontrast, cardiac computed tomography. A significant interaction term between diabetes status and treatment arm was noted in the prediction of the CAC score (p <0.001). A total of 176 subjects (85.8% men) had no diabetes and 66 subjects (80.3% men) had diabetes. The mean age was 62.9 ± 7.9 versus 63.2 ± 7.1 years, respectively. The mean low-density lipoprotein cholesterol and median triglyceride levels were not significantly different between those without and with diabetes: 77.7 ± 25.9 versus 77.1 ± 30.2 mg/100 ml, respectively, and 117.0 (78.0 to 158.0) versus 119.0 (84.5 to 201.5) mg/100 ml, respectively. Subjects with diabetes on EPA+DHA had a greater increase in CAC score than subjects with diabetes on control (median 380.7 vs 183.5, respectively, p = 0.021). In contrast, no difference occurred between the EPA+DHA and control groups in subjects without diabetes (175.7 vs 201.1, respectively, p = 0.98). In conclusion, EPA+DHA supplementation was associated with greater CAC progression in subjects with diabetes than subjects with diabetes on control over a 30-month period; whether this indicates progression of the disease burden or plaque stabilization requires further study.

RESUMEN

Both cardiovascular disease (CVD) and cognitive decline are common features of aging. One in 5 deaths is cardiac for both men and women in the United States, and an estimated 50 million are currently living with dementia worldwide. In this review, we summarize sex and racial differences in the role of fish and its very long chain omega-3 polyunsaturated fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), in preventing CVD events and cognitive decline. In prospective studies, women with higher nonfried and fatty fish intake and women and Black individuals with higher plasma levels of EPA and DHA had a lower risk of CVD. In randomized controlled trials of EPA and DHA supplementation in primary CVD prevention, Black subjects benefited in a secondary outcome. In secondary CVD prevention, both men and women benefited, and Asians benefited as a prespecified subgroup. Fish and omega-3 polyunsaturated fatty acids are associated with prevention of cognitive decline in prospective studies. In randomized controlled trials of EPA and DHA supplementation, women have cognitive benefit. DHA seems more beneficial than EPA, and supplementation is more beneficial when started before cognitive decline. Although studies in women and racial groups are limited, life-long intake of nonfried and fatty fish lowers the risk of CVD and cognitive decline, and randomized controlled trials also show the benefit of EPA and DHA supplementation. These findings should be factored into recommendations for future research and clinical recommendations as dietary modalities could be cost-effective for disease prevention.

RESUMEN

BACKGROUND AND AIMS: We previously reported that an omega-3 fatty acid index ≥4% with high-dose eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) prevented progression of noncalcified plaque. Higher coronary artery calcium (CAC) scores and progression of CAC are associated with increased cardiovascular events and mortality. We examined the effect of EPA + DHA on CAC score. METHODS: A total of 242 patients with coronary artery disease (CAD) on statin therapy were randomized to 1.86 g EPA and 1.5 g DHA daily or none (control) for 30 months. The CAC score was measured at baseline and 30-months with non-contrast, cardiac computed tomography. RESULTS: Both EPA + DHA and control groups had significant progression in CAC scores over 30 months (median change:183.5 vs 221.0, respectively, p < 0.001) despite a 13.6% reduction in triglyceride level with EPA + DHA. No significant difference was observed between groups for the total group, by baseline CAC scores of <100, 100-399, 400-999 and ≥1000 or quartiles of achieved levels of EPA, DHA and the omega-3 fatty acid index. Similar rates of CAC progression were noted in those on high-intensity statin compared to low- and moderate-intensity statin. CONCLUSIONS: EPA and DHA added to statin resulted in similar CAC progression over 30 months regardless of baseline CAC categories, statin intensity and achieved levels of EPA, DHA and the omega-3 fatty acid index.

RESUMEN

Background Residual risk of cardiovascular events and plaque progression remains despite reduction in low-density lipoprotein cholesterol. Factors contributing to residual risk remain unclear. The authors examined the role of eicosapentaenoic acid and docosahexaenoic acid in coronary plaque regression and its predictors. Methods and Results A total of 240 patients with stable coronary artery disease were randomized to eicosapentaenoic acid plus docosahexaenoic acid (3.36 g/d) or none for 30 months. Patients were stratified by regression or progression of coronary fatty plaque measured by coronary computed tomographic angiography. Cardiac events were ascertained. The mean±SD age was 63.0±7.7 years, mean low-density lipoprotein cholesterol level was <2.07 mmol/L, and median triglyceride level was <1.38 mmol/L. Regressors had a 14.9% reduction in triglycerides that correlated with fatty plaque regression (r=0.135; P=0.036). Compared with regressors, progressors had higher cardiac events (5% vs 22.3%, respectively; P<0.001) and a 2.89-fold increased risk of cardiac events (95% CI, 1.1-8.0; P=0.034). Baseline non-high-density lipoprotein cholesterol level <2.59 mmol/L (100 mg/dL) and systolic blood pressure <125 mm Hg were significant independent predictors of fatty plaque regression. Normotensive patients taking eicosapentaenoic acid plus docosahexaenoic acid had regression of noncalcified coronary plaque that correlated with triglyceride reduction (r=0.35; P=0.034) and a significant decrease in neutrophil/lymphocyte ratio. In contrast, hypertensive patients had no change in noncalcified coronary plaque or neutrophil/lymphocyte ratio. Conclusions Triglyceride reduction, systolic blood pressure <125 mm Hg, and non-high-density lipoprotein cholesterol <2.59 mmol/L were associated with coronary plaque regression and reduced cardiac events. Normotensive patients had greater benefit than hypertensive patients potentially due to lower levels of inflammation. Future studies should examine the role of inflammation in plaque regression.

RESUMEN

BACKGROUND AND AIMS: Higher coronary artery calcium (CAC) scores are associated with increased cardiovascular (CVD) events and mortality. Exercise capacity is predictive of CVD events. Our aim was to examine the relationship between exercise capacity and CAC in women and men. METHODS: CAC was measured in 203 men and 38 women with clinical coronary artery disease using multidetector coronary tomography. They were randomized to 3.36 g eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) daily or none for 30 months. Maximal exercise treadmill testing was performed at baseline with calculation of metabolic equivalents of task (METs) achieved as a measure of exercise capacity. RESULTS: Despite similar ages at baseline (64.0 ± 6.7 vs 62.7 ± 7.8 years, respectively, p = 0.225), women had lower CAC scores compared to men: 106.7 Agatston units [AU] vs 535.3, respectively, p < 0.001, and at every age (p < 0.001). Female CAC scores did not equal those of men until women were 20 years older. Higher levels of METs were associated with lower CAC scores in both women and men. After multivariate adjustment, METs was the most important predictor of CAC score in women at baseline and 30 months (p = 0.001 and 0.029, respectively) whereas only age predicted in men (p = 0.019 and 0.004, respectively). Annual CAC progression was significantly greater in men compared to women (94.8 AU/year vs 38.0, respectively, p = 0.014). No difference was observed in CAC progression in the EPA + DHA group compared to control in either men or women. CONCLUSIONS: The association of higher METs with lower CAC scores in both women and men supports recommending exercise to maximize cardiorespiratory fitness as this may minimize CAC scores and thus, potentially decrease risk for CVD events. This may be especially important for women since METs independently predicted baseline and 30 month CAC in women.

RESUMEN

In this review, sex, racial, and ethnic differences in acute coronary syndromes on a global scale are summarized. The relationship between disparities in presentation and management of acute coronary syndromes and effect on worse clinical outcomes in acute coronary syndromes are discussed. The effect of demographic, geographic, racial, and ethnic factors on acute coronary syndrome care disparities are reviewed. Differences in risk factors including systemic inflammatory disorders and pregnancy-related factors and the pathophysiology underlying them are discussed. Finally, breast arterial calcification and coronary calcium scoring are discussed as methods to detect subclinical atherosclerosis and start early treatment in an attempt to prevent clinical disease.

RESUMEN

Diabetes numeracy skills are required in the interpretation of food labels, insulin pump dosage, the interpretation of blood glucose meter data, and the determination of carbohydrate intake. This study assessed the levels and correlates of numeracy skills in Lebanese adults with diabetes to identify those most at risk of uncontrolled diabetes. In total, 299 adults with diabetes, mean age 47.4 ± 19.8 years, took the questionnaire. It consisted of self-developed items on sociodemographic and health-related factors, in addition to the Diabetes Numeracy Test-15 (DNT-15) and the Single Item Literacy Screener. Many participants (62%) scored < 10 on the DNT-15 indicating insufficient numeracy skills. DNT-15 scores were positively associated with literacy, exercise, healthy diet, perceived diabetes control, frequency of glycaemia measurement, ability to afford treatment, and ease of understanding information related to diabetes. Age, BMI, and complications were negatively correlated with DNT-15 score. Numeracy skills were higher in males, single individuals, and in people with type 1 diabetes, fewer complications, controlled HbA1c, higher income, higher education, a prior visit to a dietician, and ability to maintain personal care despite COVID-19. Interventions to strengthen numeracy skills would empower individuals with diabetes, lead to appropriate self-management behaviors, and prevent health complications in at-risk individuals.

RESUMEN

The present study deals with the assessment of acrylamide levels, dietary intake and toxicity associated with food products which constitute the main components of a Lebanese breakfast including bread, crackers, toast and kaak. Quantification of acrylamide levels was performed on a UPLC-MS/MS spectrometer and upon correlation with the results of a community survey, the carcinogenic and neurotoxic risks associated with the dietary intake of acrylamide were calculated. The average exposure to acrylamide from the investigated dietary products was found to be 5 times higher than the intake of 0.08 µg/kg-bw/day, as estimated by the NFCA (Norwegian Food Control Authority) and 3 times higher than the intake of 0.14 µg/kg-bw/day as set by the WHO (World Health Organization). MOEN and MOEC (Margin of Exposure for neurotoxic and carcinogenic risks) values ranged between 290 and 556, and between 449 and 861 respectively. Kaak, Crackers, and Toast appear to pose no neurotoxic or carcinogenic risk of concern among the entire population as well as the individual age groups. French bread and Lebanese bread pose different levels of carcinogenic risk among the entire population as well as various age groups. The results also indicate that 24% of children, 4% of young adults and 8% of adults are at both neurotoxic and carcinogenic risks.

RESUMEN

The present study aims to determine the carcinogenic and neurotoxic risks associated with acrylamide intake from cereal products. Analysis on a UPLC-MS/MS spectrometer revealed that oat-based and mixed cereals contain the highest amount of acrylamide among cereal products with levels as high as 271 and 348 µg/kg, respectively. Children were shown to exhibit both carcinogenic and neurotoxic risks regardless of the type of cereal product consumed. For adults above 50 years of age, only consumers of oat-based cereal products seem to exhibit carcinogenic and neurotoxic risks. To avoid a carcinogenic and neurotoxic risk among the Lebanese population, we propose that food processors set the maximum tolerable concentration for acrylamide in cereal products at 94.8 µg/kg product, a value which is threefolds lower than the average acrylamide levels found in this study. Alternatively, and unreasonably, the average Lebanese population and children among the Lebanese population may choose to cut down on cereal consumption by 1.7- and 7.2-folds respectively, should they want to avoid a health hazard as a result of acrylamide intake. The industry should also respond by optimizing the production process in a way to reduce acrylamide levels in cereals.

RESUMEN

BACKGROUND AND OBJECTIVES: Acute kidney injury (AKI) is common in critically ill patients and is associated with a high mortality rate. Pre-renal azotemia, suggested by a high blood urea nitrogen to serum creatinine (BUN:Cr) ratio (BCR), has traditionally been associated with a better prognosis than other forms of AKI. Whether this pertains to critically ill patients is unknown. METHODS: We conducted a retrospective observational study of two cohorts of critically ill patients admitted to a single center: a derivation cohort, in which AKI was diagnosed, and a larger validation cohort. We analyzed associations between BCR and clinical outcomes: mortality and renal replacement therapy (RRT). RESULTS: Patients in the derivation cohort (N = 1010) with BCR >20 were older, predominantly female and white, and more severely ill. A BCR >20 was significantly associated with increased mortality and a lower likelihood of RRT in all patients, patients with AKI and patients at risk for AKI. Patients in the validation cohort (N = 10 228) with a BCR >20 were older, predominantly female and white, and more severely ill. A BCR >20 was associated with increased mortality and a lower likelihood of RRT in all patients and in those at risk for AKI, BUN correlated with age and severity of illness. CONCLUSIONS: A BCR >20 is associated with increased mortality in critically ill patients. It is also associated with a lower likelihood of RRT, perhaps because of misinterpretation of the BCR. Clinicians should not use a BCR >20 to classify AKI in critically ill patients.

RESUMEN

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a well-documented postoperative complication but infrequently seen after gynecologic procedures. Clinical presentation is often insidious, and neurologic sequelae may be severe, especially in women. We report the first published case of postoperative hyponatremia due to SIADH after vaginal reconstructive surgery. Our patient sustained a tonic-clonic seizure on postoperative day 2 in the setting of profound hyponatremia. Early detection and prompt treatment allowed her to achieve a complete recovery. Familiarity with uncommon complications of vaginal surgery is important. Prompt initiation of treatment can prevent potentially fatal consequences.

RESUMEN

BACKGROUND: The Personal Digital Assistant (PDA) has become nowadays a powerful and essential tool for many physicians. Its promising success in the near future and the lack of information in regard to its use in Lebanon led to this transverse study. METHODS: A questionnaire was submitted to the doctors, residents and interns of Hôtel-Dieu de France (HDF) Hospital (Beirut), during March-April 2004 in order to evaluate the use of PDAs, the preferences and the needs of the medical personnel and to propose solutions which can meet its needs. RESULTS: The answers' rate to the questionnaire is 70.3% (303 answers). The PDA possession rate is 3036%; it is significantly more important in physicians compared to surgeons. Among those having a PDA, the operating system Palm dominates with 60% with a current tendency towards the purchase of Pocket PC; the operating system Pocket PC dominates the Phone PDAs. Approximately one third use their PDA ineffectively and admit having difficulties which greatly reduce its use in the medical field. Lexi-Drugs is the most used pharmaceutical guide, Sanford Guide the most used microbiological guide, iSilo the most used medical textbooks reader. More than 85% do not use any program to follow up their patients or read medical journals. Two thirds recognize the beneficial role of the PDA on the quality and the speed of the medical practice, one third consider that it reduces medical errors. The availability of medical programs is significantly more important for Palm. Among the subjects not having a PDA, 47% hope to buy one in the year to come; the possession rate of PDAs is estimated to reach 69.3% in 2010. Computerization of the medical data, installation of a wireless network, courses on the use of PDAs in the medical field, etc., are needs considered to be useful by 60-80% of the responders. CONCLUSION: Many medical utilities are already computerized. They still have to be presented in a format compatible with PDAs to answer a great part of the needs. A guided hospital policy and an educational program are needed to increase the usefulness of PDAs in the medical field.
