    Abstract Previous studies have linked elevated plasma trimethylamine N-oxide (TMAO) levels to poor renal function. The relationship between TMAO and chronic kidney disease (CKD) in type 2 diabetes (T2D) is still unclear. We investigated the association between plasma TMAO levels and CKD in patients with T2D. A cross-sectional study of 133 patients with T2D with or without CKD has been conducted. Blood biomarkers of kidney function, diabetes, and inflammation were assessed in the study participants. Plasma TMAO levels were quantified using UPLC-MS/MS. People with T2D and CKD exhibited significantly higher plasma TMAO levels [10.16 (5.86-17.45) µmol/L] than those without CKD [4.69 (2.62-7.76) µmol/L] (

    Abstract Background: Middle East Respiratory Syndrome (MERS) is a respiratory disease caused by a novel coronavirus that was identified in 2012 in Saudi Arabia. It is associated with significant mortality and morbidity. We identified factors associated with the Middle East Respiratory Syndrome-Coronavirus (MERS-CoV) infection among suspected cases presented with sign and symptoms of upper respiratory infection or exposure to the virus. We also looked at the impact of medication history on virus transmission.
    Method: We included subjects with suspected MERS-CoV infection and confirmed cases of MERS infection. Subjects were excluded if there were any missing data that prevent the final analysis. Descriptive statistics were used to report demographic data. Percentages and frequencies were used to summarize the categorical variables, while means and standard deviations were calculated for continuous variables. Logistic regression was used to assess the risk of MERS-CoV infection among the suspected cases. A value of
    Results: A total of 16,189 suspected cases were identified, complete data were analyzed for 3154 to assess factors that are independently associated with MERS-CoV infection. MERS-CoV infection was associated with age (adjusted odds ratio [AOR] = 1.06; 95% CI [1.02-1.098], P-value = 0.004), male gender (AOR = 1.617; 95% CI [1.365-1.77], P-value < 0.001) and diabetes (AOR = 1.68; 95% CI [1.346-1.848], P-value = 0.002. There was no significant association with the other comorbidities. Medication history was not associated with an increase or decrease the likelihood of the infection.
    Conclusions: MERS-Cov infection is more common in male, advanced age and diabetes. No medications were associated with an increase or decrease the likelihood of the infection. This is important to focus on screening and detection to this patient population.

    Abstract Animal and human studies have reported conflicting results on the relationship between circulating trimethylamine N-oxide (TMAO) levels and risk of Type 2 diabetes (T2D). This study aimed to compare plasma TMAO levels in people with or without T2D and explore the association of TMAO and T2D. A prospective case-control study of 297 participants, 164 healthy controls and 133 patients with T2D, was conducted. TMAO levels were quantified by UPLC-MS/MS. Comorbidities, dietary patterns, physical activity, and blood biomarkers were assessed. Median (IQR) plasma TMAO levels were significantly higher in diabetes cases (4.95 (2.84−8.35) µmol/L) compared to healthy controls (3.07 (2.05−4.82) µmol/L) (p < 0.001). The association between TMAO and T2D was significant in the non-adjusted Model 1 (p < 0.001) and after adjusting for confounders of diabetes including age, BMI, and level of education in Model 2 (p = 0.04). When the association was further adjusted for physical activity and diet in Model 3, plasma TMAO levels at only the highest quartile (>6.40 µmol/L) were associated with the risk of diabetes (OR = 3.36, 95% CI [1.26, 9.04], p = 0.02). The results presented suggest an association between plasma TMAO levels and T2D. A significant correlation was found between red meat consumption and increased levels of TMAO in T2D patients. A longitudinal study is warranted to further evaluate the correlation between TMAO and T2D.

    Abstract Background: Cardiovascular diseases (CVDs) are the most common cause of disease-related death in Saudi Arabia. The incidence of CVDs continues to increase, presenting a major health care problem. Nonprescription medications are widely used by patients with CVD and may cause adverse drug events, either by worsening the disease or by harmfully interacting with prescribed medications. We investigated the patterns of nonprescription medication utilization and the factors associated with their use in patients with CVD.
    Methods: This was a cross-sectional study conducted at the Cardiology Clinics of an academic tertiary health care center. Participants were asked about their sociodemographic characteristics, medical history and frequency of using nonprescription medications including over-the-counter (OTC) products, dietary supplements, and herbal products. Moreover, we investigated the participants' sources of information about nonprescription medications. Multivariate logistic regression analysis was conducted to examine the predictors of nonprescription medication use.
    Results: A total of 209 participants were interviewed. The mean age of the participants was 56 ± 15 years, and 110 (52.6%) were female. Of the 209 participants, 116 (55%) reported routine use of nonprescription medications. Black seeds and garlic were the most frequently used herbal products. Acetaminophen, cold/cough remedies, and ibuprofen were the most commonly reported OTC drugs. Of the surveyed patients, 54 (46.5%) used nonprescription medications to manage cardiovascular conditions specifically. Compared with other comorbidities, diabetes mellitus was associated with a higher use of nonprescription medications.
    Conclusion: In patients with CVD, the routine use of nonprescription medications was common for a number of reasons. Health care providers should proactively discuss nonprescription use with their CVD patients to avoid potential harmful outcomes.

    Abstract Background: Metformin associated lactic acidosis (MALA) is a rare but lethal complication. There is no consensus regarding when to stop and resume metformin in patients who undergo coronary artery bypass grafting (CABG). This study aimed to determine if uninterrupted metformin administration in patients with diabetes undergoing CABG increases the risk of lactic acidosis.
    Methods: Over a span of 12 months (2015-2016), 127 patients with type 2 diabetes underwent isolated CABG. Of those, 41 patients (32%) continued taking metformin and 86 patients (68%) took other antidiabetic agents. Patients taking metformin took the drug until the day of surgery and resumed taking it 3 h after extubation.
    Results: There were no differences in clinical outcomes or complications between groups. Serial measurement of cardiac, liver, and kidney biomarkers were similar between groups. The mean peak lactic acid level was significantly higher in the non-metformin users (5.4 ± 2.6 vs. 7.4 ± 4.1 mmol/l; P = 0.001). Multivariable logistic regression analysis identified the need for vasopressor administration as an independent predictor of lactic acidosis (odds ratio: 7.3, 95% confidence interval: 2.5-20.6; P < 0.001).
    Conclusion: In the absence of risk factors associated with persistent lactic acidosis, such as shock or acute kidney or liver injury, continued peri-operative metformin administration was not associated with the occurrence of lactic acidosis in patients undergoing CABG. Elevated lactic acid levels seem to be directly related to tissue anoxia caused by escalating vasopressor support after surgery.

    Abstract Introduction: This study conducted to assess the health literacy level among patients who have poor understanding of the medications' labels in Saudi Arabia.
    Methods: This multi-center cross-sectional study was conducted on two phases. In the 1st phase, 511 patients waiting for their medications in the outpatient pharmacies of four major hospitals in Saudi Arabia were interviewed to assess their understanding ability of the labels of five of the commonly prescribed medications. Those participants who misunderstood the medications' labels were enrolled in the 2nd phase of the study to assess their health literacy level. The validate Arabic Single Item Literacy Screener (SILS) was used to assess the health literacy level.
    Analysis: The sample characteristics were described by mean and percentage. Both Chi-square test and logistic regression model were used to figure out the association between health literacy with the main affecting factors.
    Results: Almost 38.6% (n = 197) of the participants in phase-1 misunderstood the medications' labels. Nearly, 11.2% (n = 22) of them had low health literacy level. Participants who had low education level and low socioeconomic status were more likely to have low health literacy [adjusted odds ratio (AOR) = 2.94; 95% confidence interval (95%CI) (1.03-8.404); P-value = 0.044], [AOR = 5.28; 95%CI (1.118-24.943); P-value = 0.036], respectively.
    Conclusion: Low health literacy was associated with low education level and low socioeconomic status of the patients.

    Abstract Background: Metformin is an oral antidiabetic agent belonging to the biguanide class of antidiabetics. Possible novel applications for metformin in cardiovascular disease might exist. The aim of this study was to verify a possible association between pre-operative metformin administration and protection against ischemia-induced liver injury in diabetic patients undergoing coronary artery bypass grafting (CABG) surgery.
    Methods: A retrospective case-control series was conducted at a single center. Two hundred consecutive diabetic patients underwent isolated on-pump CABG during a 12-month span (July 2015 - July 2016). Metformin was uninterrupted in patients who took this drug prior to CABG; 68 patients were metformin users (34%) while 132 patients were taking other antidiabetic agents (66%). Liver enzymes and other organ markers were consecutively recorded daily for 7 days after surgery and expressed as medians with interquartile range (IQR).
    Results: Both the metformin and non-metformin group of patients had similar pre-operative demographic characteristics. The median (IQR) post-operative cardiac enzyme creatinine kinase (CK) MB fraction was significantly lower in the metformin group [46.4 U/L (35.8-66.5)
    Conclusions: In this limited retrospective study, the diabetic patients who took metformin before and after undergoing CABG appeared to have a reduced post-operative surge in the total bilirubin and transaminase liver enzymes. Metformin's role in mitigating oxidative stress in liver cells might explain this observation. Further experimental studies are warranted to verify this possible effect.

    Abstract Background: The use of tyrosinase has confirmed to be the best means of recognizing safe, effective, and potent tyrosinase inhibitors for whitening skin. Twenty-four 2-phenoxy(thiomethyl)pyridotriazolopyrimidines were synthesized and characterized in our previous studies.
    Objective: The present work aimed to evaluate their cytotoxicity against HepG2 (hepatocellular carcinoma), A549 (pulmonary adenocarcinoma), MCF-7 (breast adenocarcinoma) and WRL 68 (embryonic liver) cell lines.
    Methods: MTT assay was employed to investigate the cytotoxicity, and a tyrosinase inhibitor screening kit was used to evaluate the Tyrosinase (TYR) inhibitory activity of the targets.
    Results: The tested compounds exhibited no considerable cytotoxicity, and nine of them were selected for a tyrosinase inhibitory test. Compounds 2b, 2m, and 5a showed good inhibitory percentages against TYR compared to that of kojic acid (reference substance). Molecular docking was performed to rationalize the Structure-Activity Relationship (SAR) of the target pyridotriazolopyrimidines and analyze the binding between the docked-selected compounds and the amino acid residues in the active site of tyrosinase.
    Conclusion: The target pyridotriazolopyrimidines were identified as a new class of tyrosinase inhibitors.

    Abstract Background Surgical site infections can have a significant impact on cardiac surgical outcome. The liver plays an important role in infection prevention. This study aimed to retrospectively determine whether transient postoperative liver dysfunction after coronary bypass surgery increased surgical site infections. Methods A modified version of the Schindl scoring scale for liver dysfunction was adapted to objectively quantify transient liver dysfunction in the first 7 days after on-pump coronary artery bypass grafting. A retrospective analysis of clinical outcomes at 30 months postoperatively was performed on data of 575 patients who underwent coronary artery bypass between 2014 and 2016. The patients were categorized into a liver dysfunction group (Schindl score ≥ 4) and a non-liver dysfunction group (Schindl score < 4). Results The liver dysfunction group (47.3%) had significantly more patients who were obese, current smokers, and had diabetes, renal impairment, and peripheral vascular disease. Surgical site infections occurred predominantly in the liver dysfunction group (12.1% vs. 0.3%, p < 0.001). The independent predictors of surgical site infection were liver dysfunction, body mass index > 30 kg m
