Development and validation of a short tool to assess the awareness of hypertensive disorders of pregnancy: a cross-sectional study among pregnant women in Lebanon.

BACKGROUND: Hypertensive disorders of pregnancy (HDPs) are responsible for most perinatal and fetal mortality. Few programs are patient-centered during pregnancy, thereby increasing the risks of misinformation and misconceptions among pregnant women and, as a result, malpractices. OBJECTIVE: This study aims to develop and validate a form to assess the knowledge and attitudes of pregnant women about HDPs. STUDY DESIGN: A cross-sectional pilot study was conducted over 4 months, targeting 135 pregnant women from 5 obstetrics and gynecology clinics. A self-reported survey was developed and validated, and an awareness score was generated. RESULTS: The mean maternal age of the participants was 27.3 (5.3) years. About 80% of the participants reported that they monitored their weight during pregnancy, and 70.4% monitored their blood pressure, out of which 73.8% performed it at the doctor's clinic only. Overall, participants had a total score of 16.9 (3.1) over 25 with higher attitude scores than knowledge scores. Less than half of the patients (45.2%) knew the cut-off for hypertension. With respect to knowledge statements, higher scores were noted for statements related to the symptoms of HDPs, and lower scores were reported for statements related to some HDP complications. Older women and those who monitored their blood pressure during pregnancy had significantly higher awareness scores. Those working had higher awareness of HDPs (67.4%), whereas about half of nonworkers (53.9%) showed lower awareness scores (P=.019). CONCLUSION: Pregnant women had moderate awareness of HDPs. The short 25-item tool developed in the present study can be used in obstetric clinics to explore the awareness of women of HDPs.

Impact of the COVID-19 pandemic on the consumption patterns of psychotropic drugs and predictors of limited access to medication.

Background: Despite the efforts of the health system to improve access to medications during the coronavirus disease of 2019 (COVID-19) pandemic, such as online consultations, encouraging generic prescriptions, and other measures to limit the storage of medication, psychotropic patients faced significant challenges in accessing their medications. Objectives: This study aimed (1) to compare the consumption of psychotropics before and during the pandemic, (2) to assess the association between having difficulties finding the medications and the general characteristics of the patients, and (3) to assess the predictors of these difficulties. Design: A case-control study was performed in which 128 patients (cases) were recruited during the pandemic (July-October 2021), and 256 patients (controls) using psychotropics before the pandemic were matched for age and sex. Methods: Data were collected using a uniform survey given to patients using psychotropics and filled out at their time and place preferences. Results: More patients used antipsychotics and anti-anxiety medications before the pandemic, while antidepressants were used more during the pandemic. Almost half of the patients reported facing difficulties finding their medications in both time frames. Before the pandemic, these difficulties were noted per increase in age and being employed and were less faced if patients had medical assistance or lived in the north of Lebanon. However, more patients reported having difficulties accessing their medication during the pandemic, with no significant differences. Conclusion: The consumption of psychotropic drugs was higher among cases. All patients faced challenges in accessing their medication throughout the pandemic, while older and employed patients had more limitations before the pandemic. Further investigations exploring viable solutions are recommended in order to maintain sustainable access to treatment.

Medication prescribing errors: data from seven Lebanese hospitals.

INTRODUCTION: Medication prescribing errors are made all over the world. However, exact data about them are lacking in Lebanon. Our objective was to describe medication errors, including drug-drug interactions in medication orders given to patients admitted to Lebanese hospitals. METHODS: A prospective study was carried out on 313 patients taken from seven Lebanese hospitals; 1826 medication orders were assessed for errors and 456 drug-drug interactions were found. Data was entered and analyzed on SPSS. RESULTS: Around 40% of medication orders were judged to comprise at least one prescribing error, mainly no ordering of parameters monitoring (20%), unnecessary medication (9%), and no indication (7%). Errors occurred mainly in the pediatrics (50%) and internal medicine wards (40%). Having an infectious or gastrointestinal problem almost doubled the risk of medication prescribing error. Antiulcer agents, NSAIDs, antibiotics and steroidal agents were the medications mainly involved. Meanwhile, 12 adverse medication events were reported, with an odds ratio of association to a medication error of 7.4 (p = 0.004). As for drug-drug interaction (DDI), prescriptions comprised zero to 29 interactions, involving medications with low margin of safety such as acenocoumarol, amiodarone and valproate. Pharmacodynamic interactions were mainly found (60%). The majority of DDI were of high clinical significance and well documented (80%), with moderate (59%) to major (17%) severity. CONCLUSION: These results highlight the urgency of an intervention to improve patients' outcomes and avoid deleterious impact of inadequate medication use in Lebanon. The presence of a clinical pharmacist, the inclusion of computerized systems and the application of drug management policies are suggested to decrease medication prescribing errors and enhance the physician attention to DDI.

Evaluation of risk factors and drug adherence in the occurrence of stroke in patients with atrial fibrillation.

BACKGROUND: Atrial fibrillation (AF) patients are at high risk of developing a stroke and anticoagulant medications are generally prescribed to prevent stroke in AF population. OBJECTIVE: This study aims to evaluate stroke risk factors among hospitalized patients with AF and to assess the level of adherence to medications in AF patients and their relation with stroke. METHODS: This is a case-control study conducted between June 1st, 2018 and December 31th, 2018 among AF patients admitted to seven tertiary Lebanese hospitals. Data were collected using a standardized questionnaire. Adherence to medications was assessed using the Lebanese Medication Adherence Scale-14. Odds ratios (OR) expressed the strength of association between the independent variables and the dependent variable and were estimated using unconditional logistic regression adjusted for confounding factors. P<0.05 determined statistical significance. RESULTS: In total, 174 cases of AF patients were included with 87 cases and 87 controls. The risk of stroke among AF significantly increased with the presence of a history of hypertension, aOR 16.04 (95%CI, 2.27-113.37; p=0.005), history of coronary heart disease/myocardial infarction, and history of obesity. Anticoagulant medication significantly decreased the risk of stroke among AF patients, aOR 0.27 (95%CI, 0.07-0.98; P=0.047). High adherence to medications was significantly associated with a reduced risk of stroke, aOR 0.04 (95%CI, 0.01-0.23; p<0.001). CONCLUSIONS: Having a history of hypertension is one of the strongest risk factors for stroke among AF patients in Lebanon. While anticoagulant medication use was associated with a reduced risk for stroke, high adherence to medications is critical for stroke prevention. Public health interventions are needed to tackle low-adherence to medication and prevent stroke among AF patients.

Rheumatoid Arthritis in the Lebanese Adults: Impact on Health-Related Quality of Life.

Rheumatoid Arthritis (RA) is a chronic inflammatory disabling disease with significant impact on the Quality of Life (QOL) of patients. Information on the effects of RA on Health-related Quality of Life (HRQoL) is lacking in the Lebanese population. The objective of this study was to evaluate QOL of RA patients compared with non-RA subjects and to suggest possible predictors of their QOL in Lebanon. We conducted a case-control observational study among individuals visiting the external clinics at three hospitals and different private clinics; the QOL was measured using the SF-36 questionnaire administered face to face to the study population, applied to RA (N = 90) and non-RA (N = 180) groups. RA presented lower Physical Component Scores (PCS) and Mental Component Scores (MCS) as well as overall QOL scores. Among RA patients, MCS and QOL were significantly decreased with morning stiffness duration (ß = -9.211, p = 0.013 and ß = -9.190, p = 0.009, respectively). The frequency of practicing sport per week increases PCS and QOL (ß = 6.692, p = 0.002 and ß = 6.148, p = 0.003, respectively). Workability has a positive effect on PCS (ß = 5.546, p = 0.022) and time between blood transfusion and the onset of the disease has a positive impact on MCS (ß = 8.415, p = 0.007). To improve QOL of patients with RA, health professionals have to take these results into consideration while treating their patients.

Validation of diabetes medication adherence scale in the Lebanese population.

AIM: To validate the Diabetes Medication Adherence Scale (DMAS-7), determine its concordance with another validated scales and to assess factors affecting medication adherence. METHODS: A cross-sectional study was conducted on a sample of Lebanese patients with diabetes using a questionnaire. The level of adherence was measured using the DMAS-7 and the Lebanese Medication Adherence Scale (LMAS-14). Bivariate and multivariate analyses were conducted, and the scale was validated in terms of reliability, predictive ability, and construct validity using SPSS version 19. RESULTS: Out of 300 eligible patients, the rate of adherence was 33.7%. Measures of validity showed good reliability (Cronbach alpha = 0.627), and good construct validity with LMAS-14 (Spearman's rho = 0.846; Cohen's kappa = 0.711). DMAS-7 was found to be both correlated with LMAS-14 (ICC average measure = 0.675; p-value <0.001) in addition to possessing a better predictive value. Thus, DMAS-7 showed to have good concordance and increased validity compared to LMAS-14. Having an optimal glycated hemoglobin (HbA1C) (OR = 0.779; p = 0.001) and performing regular physical activity (OR 2.328; p = 0.002) increased medication adherence. CONCLUSION: The DMAS-7 showed to be reliable and valid instrument superior to LMAS-14 in predicting adherence levels to oral anti-diabetic medications, and thus can be used to achieve better glycemic outcomes.

Adherence to levothyroxine among patients with hypothyroidism in Lebanon.

BACKGROUND: Non-adherence to medication schedules by patients with chronic illnesses can have serious consequences, including poor clinical outcomes, higher hospitalization rates, and increased healthcare costs. Hypothyroidism is a chronic illness with simple treatment, yet non-compliance is common. AIMS: This study aimed to evaluate treatment adherence to levothyroxine therapy in Lebanese population by estimating the proportion of adherent hypothyroidism patients and assess factors affecting the adherence to treatment. METHODS: A cross-sectional survey between May and July 2015 included 337 patients. Patients were approached by a community pharmacist during their visit to buy their levothyroxine drug and were asked to fill the questionnaire. RESULTS: Among these patients, 14.5% showed high adherence, 30.6% medium adherence, and 54.9% low adherence to medication. The mean adherence score was 5.53 ± 1.86 points. The results of a logistic regression showed that age (ORa=1.036), visiting the endocrinologist once every month (ORa=27.77), and the fact that the physician gave the patient information about the disease (ORa=2.898) would significantly increase the adherence to the medication. In addition, having one (ORa=0.365) or two comorbidities (ORa=0.232) in addition to hypothyroidism, postponing/cancelling medical appointments at the last minute (ORa=0.358), the number of waterpipe smoked per week (ORa=0.621) and the number of alcohol glasses drunk per week (ORa=0.631) would significantly decrease the adherence score. CONCLUSION: Educational programmes should be implemented, doctor-patient and pharmacist-patient relationship could be improved and new treatment regimens be considered in order to enhance patient adherence.

Evaluation of antidiabetic medication adherence in the Lebanese population: development of the Lebanese Diabetes Medication Adherence Scale.

OBJECTIVE: To evaluate factors affecting adherence to oral antidiabetic treatment in the Lebanese population and to develop the Diabetes Medication Adherence Scale (DMAS) based on these factors. METHODS: A cross-sectional study was conducted on a sample of Lebanese diabetic patients. Data were collected using a structured questionnaire. The level of adherence was measured using the Lebanese Medication Adherence Scale (LMAS-14). Bivariate analyses and multivariable analysis was done using SPSS. Psychometric evaluation of DMAS included an assessment of internal consistency, factor analysis, evaluation of sensitivity and specificity. Criterion-related validity was assessed by comparison with LMAS-14 measure of adherence. KEY FINDINGS: A total of 500 patients were recruited. 39.2% were adherent to treatment. Long working hours, increased number of oral antidiabetic medication per day, drug discontinuation when travelling, longer duration of diabetes and treatment burden were among factors that decreased adherence. While understanding the treatment regimen, following up physician recommendations and following up the recommended diet contributed to good medication adherence. The final 7-item scale (DMAS) had a good internal consistency (Cronbach's α = 0.612) and a good correlation and agreement with LMAS-14 (Spearman's rho = 0.699, Cohen's kappa = 0.566). Patients with high DMAS scores were significantly more likely to have controlled glycaemia (P < 0.05). Sensitivity and specificity reached 70.39% and 51.47%, respectively. CONCLUSION: Adherence to oral antidiabetic treatment is suboptimal in Lebanon. The DMAS is a reliable instrument for assessing adherence and predicting poor glycaemic control in clinical practice, but requires further validation in other populations.

Evaluation of medication adherence among Lebanese diabetic patients.

BACKGROUND: Diabetes type 2 is considered one of the main public health concerns. Lack of adherence to treatment leads to poor therapeutic outcome, poor glycemic control, and high risk for developing diabetes complications. OBJECTIVES: The aim of this study is to evaluate adherence to oral antidiabetic medication in Diabetes type 2 Lebanese patients, and to evaluate factors leading to low adherence. METHODS: A cross-sectional study was conducted in outpatients endocrinology clinics of two hospitals and four private clinics located in Beirut-Lebanon. Data was collected using a well-structured questionnaire by trained pharmacists. Adherence level was measured by the Lebanese Medication Adherence Scale (LMAS-14). Bivariate and multivariate analyses were conducted using SPSS version 20. RESULTS: Overall, 245 patients were included in the study with the majority being females (54.3%) and obese (47.8%). Only 29% of the participants had controlled glycemia (HbA1c <7%) with 31.8% of subjects had high adherence to their medication compared to 68.2% with low adherence. Increased working hours/day was associated with a decrease in adherence to oral antidiabetic medication (OR=0.31; 95% CI 0.11:0.88; p=0.029). Other factors significantly associated with decreased adherence to treatment were forgetfulness, high drug costs, complex treatment regimens, experiencing side effects, and perception of treatment inefficacy. Postponing physician office visits also decreased the probability of being adherent to oral antidiabetic medication (OR=0.36; 95% CI 0.15:0.86; p=0.022). Skipping or doubling the dose in case of hypo/hyperglycemia and the sensation of treatment burden also decreased medication adherence (OR=0.09; 95% CI 0.02:0.34; p=0.001, and OR=0.04; 95% CI 0.01:0.13; p<0.001 respectively). CONCLUSIONS: Adherence to oral antidiabetic medication is low for Lebanese patients, which leads to a poor glycemic control and increases the diabetes complications. Intervention programs including patient education strategies are essential to improve medication adherence.

Middle Iron-Enriched Fructose Diet on Gestational Diabetes Risk and on Oxidative Stress in Offspring Rats.

Gestational diabetes mellitus (GDM) is associated with increased insulin resistance and a heightened level of oxidative stress (OS). Additionally, high iron consumption could also increase insulin resistance and OS, which could aggravate GDM risk. The aim of this study is to evaluate a high fructose diet (F) as an alternative experimental model of GDM on rats. We also have evaluated the worst effect of a fructose iron-enriched diet (FI) on glucose tolerance and OS status during pregnancy. Anthropometric parameters, plasma glucose levels, insulin, and lipid profile were assessed after delivery in rats fed an F diet. The effects observed in mothers (hyperglycemia, and hyperlipidemia) and on pups (macrosomia and hypoglycemia) are similar to those observed in women with GDM. Therefore, the fructose diet could be proposed as an experimental model of GDM. In this way, we can compare the effect of an iron-enriched diet on the metabolic and redox status of mother rats and their pups. The mothers' glycemic was similar in the F and FI groups, whereas the glycemic was significantly different in the newborn. In rat pups born to mothers fed on an FI diet, the activities of the antioxidant enzyme glutathione peroxidase (GPx) and glutathione-S-transferase in livers and GPx in brains were altered and the gender analysis showed significant differences. Thus, alterations in the glycemic and redox status in newborns suggest that fetuses are more sensitive than their mothers to the effect of an iron-enriched diet in the case of GDM pregnancy. This study proposed a novel experimental model for GDM and provided insights on the effect of a moderate iron intake in adding to the risk of glucose disorder and oxidative damage on newborns.

Association between iron level, glucose impairment and increased DNA damage during pregnancy.

Elevated circulating ferritin has been reported to increase the risk of gestational diabetes mellitus (GDM). When high ferritin translates into high iron stores, iron excess is also a condition leading to free radical damage. We aimed to evaluate the relationship between oxidative stress (OS) induced by iron status and GDM risk in non iron-supplemented pregnant women. METHODS: This was a pilot observational study conducted on 93 non-anemic pregnant women. Iron status was assessed at the first trimester of gestation. Blood sampling was done at 24-28 weeks' gestation for oral glucose tolerance test (OGTT), insulin and biological markers of oxidative damage tests. RESULTS: A significant increase in DNA damage was found in patients who developed GDM. Women with elevated DNA damage had a six-fold increased risk of developing GDM (Exp (B)=6.851, P=0.038; 95% CI [1.108-42.375]). The serum ferritin levels at first trimester were significantly correlated to lipid peroxidation (rho=0.24, p=0.012). The stratified analysis suggests that ferritin is a modifying factor for the correlation of oxidative stress (OS) and glucose intolerance. CONCLUSION: Moderate ferritin levels due to iron intake without iron-supplement, at early pregnancy is a modifying factor for the correlation of oxidative damage and glucose intolerance in pregnant women. Larger studies to evaluate the risk of food iron intake induced increased oxidative damage in offspring are warranted to propose nutrition advice regarding iron intake in women with a high risk of GDM.

Risk factors and quality of life of dyslipidemic patients in Lebanon: A cross-sectional study.

The main objective of this study was to identify the risk factors of dyslipidemia and measure its impact on patients' quality of life (QOL). Secondary objectives were to determine the percentage of dyslipidemia and assess the predictive factors affecting patients' QOL. A cross-sectional study was conducted in a sample of Lebanese population. A standardized questionnaire was developed to assess the QOL using the Short form-36 (SF-36) score. A total of 452 individuals were interviewed, of which 59.5% were females. The mean age was 43.3±15.6years, and 24.8% had dyslipidemia. The results show a lower overall QOL score among dyslipidemic patients compared with controls (57.9% and 76.5%, respectively; p<0.001). Waterpipe smoking [adjusted odds ratio (ORa)=4.113, 95% confidence interval (CI): 1.696-9.971, p=0.002], hypertension (ORa=3.597, 95% CI: 1.818-7.116, p<0.001), diabetes (ORa=3.441, 95% CI: 1.587-7.462, p=0.002), cigarette smoking (ORa=2.966, 95% CI: 1.516-5.804, p=0.001), and passive smoking (ORa=2.716, 95% CI: 1.376-5.358, p=0.004) were significantly associated with dyslipidemia in individuals older than 30years. A higher overall QOL score (p=0.013) was observed in patients treated with statins in comparison with other lipid-lowering medications. In addition to clinical and economical consequences, dyslipidemia may have a significant impact on patients' QOL. Further research is needed to confirm the impact of treatment on dyslipidemic patients' QOL in order to maximize the overall benefits of therapy.

Evaluation of medication adherence in Lebanese hypertensive patients.

Controlling hypertension is essential in cardiovascular diseases. Poor medication adherence is associated with poor disease outcomes, waste of healthcare resources, and contributes to reduced blood pressure control. This study evaluates treatment adherence to antihypertensive therapy in Lebanese hypertensive patients by estimating the proportion of adherent hypertensive patients using a validated tool and investigates what factors predict this behavior. A questionnaire-based cross-sectional study was conducted on a random sample of 210 hypertensive outpatients selected from clinics located in tertiary-care hospitals and from private cardiology clinics located in Beirut. Adherence level was measured using a validated 8-item Modified Morisky Medication Adherence Scale (MMMAS). Among 210 patients, 50.5% showed high adherence, 27.1% medium adherence, and 22.4% low adherence to medication. Mean MMMAS score was 6.59±2.0. In bivariate analyses, having controlled blood pressure (p=0.003) and taking a combination drug (p=0.023) were predictors of high adherence. Forgetfulness (p<0.01), complicated drug regimen (p=0.001), and side effects (p=0.006) were predictors of low adherence after multiple liner regression. Logistic regression results showed that calcium channel blockers (p=0.030) were associated with increased adherence levels. In conclusion, developing multidisciplinary intervention programs to address the factors identified, in addition to educational strategies targeting healthcare providers, are necessary to enhance patient adherence.

Evaluation of risk factors and drug adherence in the occurrence of stroke in patients with atrial fibrillation

BACKGROUND: Atrial fibrillation (AF) patients are at high risk of developing a stroke and anticoagulant medications are generally prescribed to prevent stroke in AF population. OBJECTIVE: This study aims to evaluate stroke risk factors among hospitalized patients with AF and to assess the level of adherence to medications in AF patients and their relation with stroke. METHODS: This is a case-control study conducted between June 1st, 2018 and December 31th, 2018 among AF patients admitted to seven tertiary Lebanese hospitals. Data were collected using a standardized questionnaire. Adherence to medications was assessed using the Lebanese Medication Adherence Scale-14. Odds ratios (OR) expressed the strength of association between the independent variables and the dependent variable and were estimated using unconditional logistic regression adjusted for confounding factors. P<0.05 determined statistical significance. RESULTS: In total, 174 cases of AF patients were included with 87 cases and 87 controls. The risk of stroke among AF significantly increased with the presence of a history of hypertension, aOR 16.04 (95%CI, 2.27-113.37; p = 0.005), history of coronary heart disease/myocardial infarction, and history of obesity. Anticoagulant medication significantly decreased the risk of stroke among AF patients, aOR 0.27 (95%CI, 0.07-0.98; P=0.047). High adherence to medications was significantly associated with a reduced risk of stroke, aOR 0.04 (95%CI, 0.01-0.23; p < 0.001). CONCLUSIONS: Having a history of hypertension is one of the strongest risk factors for stroke among AF patients in Lebanon. While anticoagulant medication use was associated with a reduced risk for stroke, high adherence to medications is critical for stroke prevention. Public health interventions are needed to tackle low-adherence to medication and prevent stroke among AF patients

Factors affecting medication adherence in Lebanese patients with chronic diseases.

BACKGROUND: Non-adherence to prescribed medications represents an obstacle toward achieving treatment goals. This problem is more pronounced in patients with chronic illness. OBJECTIVE: To identify the extent of adherence in Lebanese outpatients with chronic diseases, and to suggest possible predictors of non-adherence in this population. The secondary objective was to assess if medication adherence affects patients' quality of life. METHODS: A questionnaire was administered face-to-face to a sample of Lebanese adults visiting the external clinics at two Tertiary Care Hospitals in Beirut. The level of adherence was assessed using the 8-item Morisky Medication Adherence Scale which was first validated. The health-related quality of life (HRQoL) of patients was measured using the EQ-5D. Linear regression and logistic regression analyses examined possible predictors of adherence. RESULTS: Out of the 148 patients included in this study, 42.6% were classified as adherent. In the univariate analyses, statistically significant predictors of high adherence included good physician-patient relationship (p=0.029) and counseling (p=0.037), a high level of HRQoL (p<0.001), and a high level of perceived health (p<0.001). Predictors of low adherence included a declining memory (p<0.001), anxiety/depression (p=0.002), little drug knowledge (p<0.001), and postponing physician appointments (p<0.001). The multivariate analyses revealed similar results. In the linear regression, the most powerful predictor of non-adherence was the disbelief that the drug is ameliorating the disease (beta=0.279), however, in logistic regression, patient who were willing to skip or double doses in case of amelioration/deterioration were found to be 7.35 times more likely to be non-adherent than those who were not (aOR=0.136, 95% CI: 0.037-0.503). CONCLUSION: The findings of this study reassure the view that patients should be regarded as active decision makers. Patient education should be regarded as a cornerstone for treatment success. Additional studies as well are needed to test the practicability and effectiveness of interventions suggested to enhance adherence.

High iron level in early pregnancy increased glucose intolerance.

High iron stores in pregnancy are essential in preventing negative outcomes for both infants and mothers; however the risk of gestational diabetes mellitus (GDM) might also be increased. We intend to study the relationship between increased iron stores in early pregnancy and the risk of glucose intolerance and GDM. This prospective, observational, single-hospital study involved 104 non-anemic pregnant women, divided into 4 groups based on the quartile values for ferritin at the first trimester of pregnancy. All participants were screened for GDM with 75-g oral glucose tolerance test (OGTT) at 24-28 weeks' gestation. We observed that ferritin levels at early pregnancy were significantly correlated to glucose level after OGTT at 1-h and 2-h (rho=0.21, p<0.05; rho=0.43, p<0.001 respectively). Furthermore, in the higher quartile for ferritin (>38.8µg/L) glycemia at 2-h OGTT was significantly higher than in the others quartiles (p=0.002). In multivariate regression analysis, serum ferritin was a significant determinant of glycemia at 2-h OGTT. Although we did not find a significant association in the incidence of GDM in women with higher serum ferritin levels, probably in reason to the limit power of our study, our data demonstrated that the role of iron excess is tightly involved in the pathogenesis of glucose intolerance. We report for the first time that high ferritin values in early pregnancy are predictors of impaired glucose tolerance in non-anemic women. Individual iron supplementation should be evaluated in order to minimize glucose impairment risk in women with high risk of diabetes.

Is oxidative stress induced by iron status associated with gestational diabetes mellitus?

Gestational diabetes mellitus (GDM) is a common pregnancy complication in high risk populations, and is associated with increased perinatal and long term outcomes for both mothers and newborns. Both its prevention and early management can be reinforced by identifying risks factors, particularly those factors influencing glucose metabolism. On the other hand, several epidemiological studies have shown an increased oxidative stress (OS) in pregnant women with GDM. Elevated OS was also reported in pregnant women supplemented with iron, which can generate OS and may also influence insulin resistance. This review summarizes the current state of knowledge, highlighting the potential relationship between OS induced by iron status and the development of GDM.

Risky substance exposure during pregnancy: a pilot study from Lebanese mothers.

BACKGROUND: The harmful effects of medication and licit substance use during pregnancy may potentially constitute a major public health concern. Our study aims to assess risky exposure of Lebanese pregnant women to drugs, tobacco, caffeine, and alcohol, and to determine their effect on postnatal outcomes. METHODS: Women at term were addressed after delivery in five university hospitals of Beirut and Mount Lebanon between February and June 2012. A standardized questionnaire was administered to them. Moreover, medical files of both mothers and their respective newborns were checked to confirm information given by mothers, and to assess the health outcome of the babies. RESULTS: Among the interviewed 350 women, active and passive smoking of tobacco (cigarette or water pipe), and consumption of category C, D, and X drugs were common during pregnancy in Lebanon; they were shown to negatively affect the neonatal outcome in multivariate analyses: they significantly decreased Apgar scores and increased the risk of underweight and medical complications of babies (P < 0.05). CONCLUSION: Our study demonstrated that Lebanese women were exposed during pregnancy to multiple medications and licit substances that affected the neonates' health. Our findings have implications for clinical obstetric practice and prevention programs in Lebanon. Efforts should be made to decrease exposure to harmful substances during pregnancy.

Adverse drug events associated with vitamin K antagonists: factors of therapeutic imbalance.

BACKGROUND: Adverse drug events (ADE) occur frequently during treatment with vitamin K antagonists (AVK) and contribute to increase hemorrhagic risks. METHODS: A retrospective study was conducted over a period of 2 years. Patients treated with AVK and admitted to the emergency room of a tertiary care hospital in Beirut were included. The aim of the study was to identify ADE characterized by a high international normalized ratio (INR) and to determine the predictive factors responsible for these events. Statistical analysis was performed with the SPSS statistical package. RESULTS: We included 148 patients. Sixty-seven patients (47.3%) with an INR above the therapeutic range were identified as cases. The control group consisted of 81 patients (54.7%) with an INR within the therapeutic range. Hemorrhagic complications were observed in 53.7% of cases versus 6.2% of controls (P < 0.0001). No significant difference was noticed between cases and controls regarding the indication and the dose of AVK. Patients aged over 75 years were more likely to present an INR above the therapeutic range (58.2%, P = 0.049). Recent infection was present in 40.3% of cases versus 6.2% of controls (P < 0.0001) and hypoalbuminemia in 37.3% of cases versus 6.1% of controls (P < 0.0001). Treatment with antibiotics, amiodarone, and anti-inflammatory drugs were also factors of imbalance (P < 0.0001). CONCLUSION: Many factors may be associated with ADE related to AVK. Monitoring of INR and its stabilization in the therapeutic range are important for preventing these events.

Statins decrease mortality in Lebanese patients with sepsis: A multicenter study.

BACKGROUND: Sepsis is a significant public health concern. The clinical response to statins is variable among sepsis patients. OBJECTIVE: The aim of the study was to determinate the effect of statin-treatment on mortality in Lebanese patients with sepsis. METHODS: A retrospective multicenter study on Lebanese patients with sepsis between January 2008 and March 2012 was conducted. Patients with a primary diagnosis of sepsis admitted to the intensive care unit of two tertiary care hospitals in Beirut were included. Patients who continued to receive statin therapy for dyslipidemia during the hospital course were included in the statin treatment group. The control group consisted of patients not taking statin. Demographic characteristics, clinical signs, standard laboratory test and treatment received were compared between these two groups using univariate analysis. Logistic regression and survival analysis were performed by SPSS. RESULTS: THREE HUNDRED FIFTY ONE LEBANESE PATIENTS WERE INCLUDED (AGE: 71.33 SD=14.97 years; Male: 56%). Among them, 30% took a statin at the doses recommended for dyslipidemia. The comparison of the two groups showed that in the statin treatment group: The mean serum level of C-reactive protein at the time of sepsis was significantly decreased (P=0.050), the length-stay at ICU significantly increased (P=0.047) and mortality significantly reduced (P<0.001). Results were confirmed by logistic regression, particularly for mortality. In the Cox regression analysis, hypothermia and shock were significantly associated with high mortality while statin treatment decreased mortality (hazard ratio = 0.540; 95% CI: 0.302-0.964; P=0.037). CONCLUSIONS: At usual doses for dyslipidemia, statin treatment decreased incidence of mortality related to sepsis and improved the survival in this Lebanese septic population. Large randomized controlled clinical trials must be realized to give conclusive results about the potential beneficial effect of statins in sepsis.
