Protective effects of combined therapy of gliclazide with curcumin in experimental diabetic neuropathy in rats

Diabetic neuropathy is the most common chronic complication of diabetes. The aim of the present study was to evaluate the protective effects of curcumin against neuropathy in gliclazide-treated diabetic rats. Diabetes was induced by an intraperitoneal injection of streptozotocin (45 mg/kg). Diabetic animals were given gliclazide (10 mg/kg, orally) alone or combined with curcumin (100 mg/kg, orally) or gabapentin (30 mg/kg, intraperitoneally as a positive control). Behavioral responses to thermal (hot plate and tail flick) and mechanical (tail pinch) pain, and some biochemical tests (serum glucose, C-peptide, peroxynitrite, lipid peroxides, and tumor necrosis factor-α) were assessed after 5 consecutive weeks of daily treatment. Combined treatment of curcumin with gliclazide significantly increased hot-plate and tail-flick latencies in comparison with that of the diabetic control group. The threshold of mechanical hyperalgesia was also significantly elevated. Serum glucose and C-peptide levels were significantly increased in the combined treatment compared with the diabetic control group, whereas serum levels of peroxynitrite, lipid peroxide, and tumor necrosis factor-α production were significantly decreased. The data suggest that the combination of curcumin with gliclazide may protect against the development of diabetic neuropathy, with favorable effects with respect to the gliclazide/gabapentin combination.

Burnout and imposter syndrome among Saudi young adults: The strings in the puppet show of psychological morbidity

Objectives:To determine the prevalence of imposter syndrome (IS) among Saudi adults and its association with burnout.Methods:Using non-probability convenience sampling, we carried out a cross-sectional analytical study among adults in Northern Saudi Arabia. Data collection toll was a self-administered questionnaire containing young imposter scale (YIS), Maslach burnout inventory (MBI) and depression, anxiety, and stress scale 21 (DASS 21). These 3 scales are valid and reliable measurement tools for measuring IS, burnout, and psychological morbidity.Results:In the study sample (n=384), imposterism was present among 222 adults (57.8%). Moderate and severe symptoms of depression were present in 217 (56.5%), symptoms of stress in 210 (54.7%), and symptoms of anxiety in 126 (32.8%). Burnout was measured in 3 domains of depersonalization, emotion exhaustion, and personal accomplishments. High degree of depersonalization was found in 221 (57.6%), higher emotional exhaustion in 246 (64.1%) while lower personal accomplishment was present in 126 (32.8%). We found statistical association between IS and gender (p<0.01), depression (p<0.001) stress (p<0.001) and all 3 domains of burnout (p<0.01). Imposter syndrome was not found associated with anxiety (p=0.97). Young imposter scale score was associated with all the 3 domains of burnout even after controlling for depression, anxiety, and stress.Conclusion:Imposter syndrome is frequent among Saudi adults and associated with all 3 burnout domains. Mental health domains like burnout, depression, stress, and anxiety were found associated with IS.     

Evaluating the frequency,consumers’ motivation and perception of online medicinal,herbal, and health products purchase safety in Saudi Arabia

ObjectivesPurchasing medicinal products from the internet has become more popular in the last three decades. Understanding consumers’ use and perception of the safety of medicinal products obtained online is essential. Therefore, this study aims to evaluate the extent of medicines purchased from the internet in Saudi Arabia, types of products, sources of information, the satisfaction, the motivational factors, and estimate consumers’ vigilance and tendency to report ADRs if occurred.DesignA prospective cross-sectional study using a custom-designed questionnaire was conducted among community adults in Saudi Arabia, age ≥ 18.SettingEvaluation of community subjects' perception towards buying medicinal products was done through the internet in Saudi Arabia from 1st July 2020 until the end of August 2020.Main outcome measure(s)The main outcome of the study was purchasing medicinal products from the internet (Yes, No).ResultsOverall, 36% of the study participants (n = 643) have ever bought medicinal products from the internet (Table 2). Of those, the most obtained was herbal medicine, supplements, or cosmetics (61.3%). Motivational factors towards purchasing medicinal products from the internet were mostly positive, with the most commonly reported agreed motivational factors were lower cost (55.7%), easy online access (54.1%), a wide variety of products (52.6%), and more privacy (43.6%). Around 60.4% of participants believed that buying medicinal products from the internet can be safe. The most perceived risk was the difficulty of distinguishing between registered online pharmacies and other unlicensed commercial websites, with only 32.7% of the participants distinguishing between registered and unlicensed commercial websites.ConclusionsThis study sheds light on the consumers’ use and perception of the safety and risks of medicinal products purchased from the internet. The study findings noticeably describe the great need to increase safety awareness about obtaining medicinal products from the internet among the Saudi community.

Effect of zinc supplementation on symptom reduction and length of hospital stay among pediatric patients with Coronavirus disease 2019 (COVID-19)

ObjectivesZinc is considered an essential multipurpose trace element because of its ability to act as a cofactor and signaling molecule. As reported in earlier studies of pediatric respiratory infection management, zinc exhibits potent immunoregulatory and antiviral properties, but its effects on pediatric patients with COVID-19 remain unknown. The aim of this study was to determine the extent to which zinc supplementation improves COVID-19 symptoms, length of hospitalization and, to determine how zinc supplementation impacts ICU admission, in-hospital mortality, need for ventilation, duration of ventilation, need for vasopressors, development of liver injury, or respiratory failure.MethodsPediatric patients younger than 18 years with confirmed COVID-19 infection during the study period (March 1, 2020, to December 31, 2021) were recruited for this retrospective cohort study. The study population was divided into two arms (zinc/no zinc supplementation as an adjunct to standard therapy).ResultsOf 169 hospitalized patients who were screened, 101 met the inclusion criteria. No statistically significant association was found between the administration of zinc as adjunctive therapy and symptom reduction, intensive care unit (ICU) admission, or mortality (p = 0.105; p = 0.941, and p = 0.073, respectively). However, zinc supplementation was associated with a statistically significant reduction in respiratory failure and length of hospitalization (p = 0.004 and p = 0.017, respectively), also, zinc administration was associated with elevated serum creatinine (p = 0.01*)ConclusionsAmong pediatric patients with COVID-19, zinc supplementation was associated with shorter hospital stay. However, there was no significant difference between the two groups in terms of symptom improvement, in-hospital mortality, or ICU admission. In addition, the study raises question about the possibility of kidney injury as indicated by high levels of serum creatinine.     

Hypoglycemia in Type 2 Diabetes Mellitus patients: A review article

Hypoglycemia is an essential issue for diabetic patients and considered a limiting factor in the glycemic management. Heterogeneity of the diseases in Type 2 Diabetes Mellitus can affect the frequency of hypoglycemia, especially when the patient has cardiovascular diseases. There are several factors that lead to hypoglycemia including sulfonylurea therapy, insulin therapy, delaying or missing a meal, physical exercise, or alcohol consumption. Long-term studies reported that repeated hypoglycemia could increase the risk of cardiovascular diseases. During Ramadan fasting, diabetic patients have high incidence of hypoglycemia. Therefore, focused education about hypoglycemia in routine life of diabetic patients and during fasting in Ramadan is important to reduce the complications.     

The Association between Changes in Coronary Artery Calcium Scores,Dietary Intake,Physical Activity,and Depression Symptoms among the Population of Gaza Strip,Palestine

BackgroundThis study aimed to identify the association between macronutrient intake, physical activity, and depressive symptoms and changes in coronary artery calcium score among the population of Gaza Strip.MethodThe study sample consisted of 269 individuals who underwent non-enhanced coronary computed tomography using 64-slice MDCT (Siemens, Germany) at Al-Shifa medical complex between September 2017 and January 2018. The study participants were divided into two groups; group one, consisting of coronary calcium calcification scoring (CAC) of greater than zero (CAC score > 0), and group two, CAC less than or equal to zero (CAC score ≤ 0). Data about macronutrient intake, physical activity, and depressive symptoms were collected using a validated self-administered questionnaire. Additionally, the participants'' anthropometric characteristics and blood biochemical markers were measured.ResultsOut of 269 participants, 45-recorded CAC score > 0; 72% of them were males with a mean age of 52.6 ± 5.4 years. Significant differences between the two groups in terms of total energy, lipid intake, and carbohydrate were found (P-value of 0.020, 0.012, and 0.034, respectively). No significant differences were recorded in protein intake, physical activity, and depression. Multivariate logistic regression analysis under adjustment for possible confounding factors revealed that macronutrient intake, physical activity, and depressive symptoms were not associated with the development of CAC in two models.ConclusionBased on our findings, macronutrient intake, physical activity, and depressive symptoms are not associated with the development of CAC among the population of Gaza.     

Oxidative stress and antioxidant status in Saudi asthmatic patients

ObjectivesAsthma is a chronic inflammatory airway disorder associated with recruitment of inflammatory cells. This study aims to clarify the role of oxidative stress and antioxidant status in the deterioration accompanied asthma.Design and methodsVitamin E, Vitamin C, superoxide dismutase (SOD), glutathione peroxidase (GPx), reduced glutathione (GSH), total antioxidant status together with the concentrations of lipid peroxides, total nitrates and oxidative DNA damage (8-oxodeoxyguanine) were determined in plasma or whole blood of 47 Saudi asthmatic patients and compared to age-matching control samples.ResultsThe present study showed that asthmatic patients have significantly decreased levels of GSH, α-tocopherol, GPx, total antioxidant status and higher levels of SOD, lipid peroxides, total nitrate and 8-oxo-dG. Vitamin C recorded more or less similar levels in both groups.ConclusionAlteration of the selected measured parameters confirms that oxidative stress and defective antioxidant status could represent the primary causative factor in the pathogenesis of asthma.     

Effects of cigarette smoke condensate on oral squamous cell carcinoma cells

Objective

Epidemiological studies have reported that tobacco use is a major etiological factor for oral cancer. Several matrix metalloproteinases (MMPs) have been shown to play important roles in the invasion and metastasis of oral squamous cell carcinomas, especially MMP-2 and MMP-9. This study examined the effects of cigarette smoke condensate (CSC) on oral cancer cells.

Design

Two oral squamous cell carcinoma cell lines, SCC-25 (metastatic) and CAL-27 (non-metastatic), were exposed to different concentrations of CSC and examined for their collagen degrading ability and MMP production using collagen degradation assays, zymograms and Western blots.

Results

Exposure to CSC increased the collagen degrading ability of the metastasizing cell line (SCC-25) by a mechanism involving increased MMP-2 and MMP-9 production.

Conclusion

CSC increased the collagen degrading ability of SCC-25 by increasing the MMP-2 and MMP-9 protein levels. Continued cigarette smoking in oral cancer patients may result in decreased survival rates due to enhanced metastatic potential of the cancer cells.
