The vascular impact of dapagliflozin, liraglutide, and atorvastatin alone or in combinations in type 2 diabetic rat model.

Diabetic dyslipidemia is a significant contributor in the pathogenesis of type 2 diabetes (T2D). The study aimed at comparing the effect of dapagliflozin, liraglutide, and atorvastatin alone or their combinations on lipids and inflammatory markers and their vascular impact in T2D rats. There were 56 male albino rats included in the study and divided into two main groups. Group A (8 rats) served as normal control. Group B (48 rats) were streptozotocin-nicotinamide-induced diabetic rats. Subgroups (B-1, B-2, B-3, B-4, B-5, and B-6) received (no medications, dapagliflozin, liraglutide, atorvastatin, dapagliflozin + atorvastatin, and liraglutide + atorvastatin), respectively. Urine albumin/creatinine ratio (UACR), glycosylated hemoglobin (HBA1c), fasting serum glucose (FSG), serum low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), TGs, lipoprotein(a) Lp (a), serum thyrotropin (TSH), highly sensitive C-reactive protein (hs-CRP) and advanced glycation end products (AGEs), were assessed. Qualitative and quantitative histological examination of kidneys focused on renal corpuscles. Dapagliflozin improved the studied parameters but with statistically insignificant increase in LDL-C, Lp (a) and significant increase in UACR. Atorvastatin improved the studied parameters but with statistically insignificant increase in FSG and HbA1C. Liraglutide and the combination groups significantly improved all studied parameters. Histologically, liraglutide and atorvastatin produced therapeutic effect, while dapagliflozin depicted nephrotoxic effect. Combination groups resulted in better effects with normalization of most of renal corpuscles. There were positive correlations between LDL-C and hs-CRP, AGEs, TSH and mesangial expansion. Combination of atorvastatin with liraglutide can improve its vasculoprotective effect. Moreover, combination of atorvastatin with dapagliflozin can ameliorate its possible nephrotoxic effect.

Smoking behaviour and patterns among university students during the Syrian crisis.

BACKGROUND: The ongoing Syrian war has resulted in many changes in the social and economic life of Syrians. To date, no study has documented the relationship between smoking behaviour and the war. AIM: To determine the prevalence of cigarette smoking among university students during the crisis in Damascus, Syrian Arab Republic, and the impact of the war on smoking behaviour. METHODS: We conducted an anonymous online cross-sectional survey of 1027 undergraduate students from all years and colleges at Damascus University. RESULTS: The overall prevalence of tobacco smoking was 24.73% for cigarettes and 30.4% for waterpipe. Prevalence of cigarette smoking was significantly higher in men, non-health profession students, and in students living away from their families. There was no significant difference in prevalence of smoking cigarettes when comparing students according to their origin (urban vs rural), year of study, and change of residence due to war. War was associated with a significant increase in mean number of cigarettes smoked daily, and 53.1% of smokers reported that the number of cigarettes consumed per day had increased since the beginning of the war. CONCLUSIONS: Increased smoking is an additional health concern in areas of conflict and may require special consideration and efforts by public health authorities.

Contexte : La guerre qui sévit en République arabe syrienne a conduit à de nombreuses modifications dans la vie sociale et économique des Syriens. À ce jour, aucune étude ne documente la relation entre les comportements tabagiques et la guerre. Objectif : Déterminer la prévalence de la consommation de cigarettes parmi les étudiants à l'université pendant la crise à Damas, en République arabe syrienne, et l'impact de la guerre sur les comportements tabagiques. Méthodes : Nous avons organisé une enquête en ligne transversale et anonyme sur 1027 étudiants de premier cycle de toutes les années et dans toutes les facultés de l'Université de Damas. Résultats : La prévalence globale du tabagisme était de 24,73 % pour la cigarette, et de 30,4 % pour la pipe à eau. La prévalence de la consommation de cigarettes était significativement plus élevée chez les hommes, les étudiants d'autres filières que celle de la santé, et chez les étudiants ne vivant plus dans leurs familles. Aucune différence significative n'a été observée pour la prévalence de la consommation de cigarettes en fonction de l'origine des étudiants [urbaine ou rurale], de leur année d'étude, ou de leur changement de résidence du fait de la guerre. La guerre était associée à une augmentation significative du nombre moyen de cigarettes consommées quotidiennement, et 53,1 % des fumeurs rapportaient que le nombre de cigarettes qu'ils consommaient par jour avait augmenté depuis le début de la guerre. Conclusions : L'augmentation du tabagisme est une préoccupation sanitaire supplémentaire dans les zones de conflit, et requiert une attention spéciale ainsi que des actions de la part des autorités de santé publique

Standard triple therapy versus sequential therapy for eradication of Helicobacter pylori in treatment naïve and retreat patients.

BACKGROUND AND STUDY AIMS: Untreated Helicobacter pylori infection causes increased risk of gastric cancer, GI morbidity and mortality. Standard treatment for eradication of Helicobacter pylori infection, is the triple therapy which consists of a proton pump inhibitor; together with two antibiotics (amoxicillin 1000mg with clarithromycin 500mg or metronidazole 400mg) given twice daily for 7-14days. Recent evidence revealed, that cure rates of Helicobacter pylori infection with triple therapy had fallen below satisfactory targets. Sequential therapy consisting of a twice daily dose of a PPI for ten days with Amoxicillin given at 1000mg twice daily in the first 5days followed by clarithromycin 500mg and Metronidazole 400mg given twice daily in the subsequent 5days, was recommended to improve eradication rates. We performed a randomised open label study to compare the efficacy of sequential against triple therapy in Helicobacter pylori naive and retreat patients. PATIENTS AND METHODS: In a randomised open label observational study 485 patients fulfilling inclusion and exclusion criteria were randomly assigned to be treated with triple therapy (n=231) or sequential therapy (n=254). Eradication of Helicobacter pylori was documented with 14C Urea breath test (UBT) performed 6weeks after the treatment. RESULTS: The intention-to-treat eradication rate was better in sequential therapy group 84.6% than triple therapy 68% (p<0.001). Eradication rates were significantly higher for treatment naive than retreat patients in triple therapy group (70.5% and 58.3%, respectively, p<0.01). A trend of a better response was observed in eradication rate for treatment naive 88.55% versus retreat 74.6% in sequential therapy group but was not statistically significant (p=0.76). Compliance was similar in the two groups, however side effects were less and the clinical response was better in the sequential therapy group.

Essential phospholipids as a supportive adjunct in the management of patients with NAFLD.

BACKGROUND AND STUDY AIMS: Treatment of nonalcoholic fatty liver (NAFLD) is important because NAFLD patients have a 1.7-fold increase in standardised age and gender matched mortality. Currently treatment is based on life style modification and managing comorbid associating disease. Other medications remain experimental. Essential phospholipid (EPL) is a nutrient for the liver, helping to maintain vitality of cell membranes where the vast majority of liver activities are regulated. We performed a randomised open label study to evaluate EPL as an adjuvant nutrient to the treatment of primary NAFLD or NAFLD with comorbid disease. PATIENTS AND METHOD: Three groups of NAFLD patients were recruited: lone (n=113), diabetes mellitus type 2 (n=107) and mixed hyperlipidaemia (n=104). Diagnosis was established by excluding other chronic liver diseases. A standard diet and physical activity plan were advised to all patients. 1800mg of EPL a day was given for 24weeks, followed by 900mg for 48weeks. RESULTS: Essential phospholipid EPL led to a significant improvement of symptoms and a mean reduction of ALT of 50.8IU and AST of 46.1IU per patient (p<0.01). Abdominal ultrasonography indicated normalisation in 4.6% and a shift from grade II to grade I in 24% of patients. Liver stiffness measurement indicated an improvement in 21.1%, with a mean reduction in the LSM of 3.1K Pascal/patient. Reducing the dosage after six months led to a limited relapse in 43.8-63.2% of patients, for lone and NAFLD with co-morbid conditions. CONCLUSION: Essential phospholipid (EPL) as a nutritional supplement resulted in a significant improvement in clinical parameters and transaminases for all NAFLD patients. Ultrasound and LSM revealed modest improvement. There is a need for uninterrupted maintenance to avoid relapse.

Morphometric analysis of osteonal architecture in bones from healthy young human male subjects using scanning electron microscopy.

The shape and structure of bones is a topic that has been studied for a long time by morphologists and biologists with the goal of explaining the laws governing their development, aging and pathology. The osteonal architecture of tibial and femoral mid-diaphyses was examined morphometrically with scanning electron microscopy in four healthy young male subjects. In transverse sections of the mid-diaphysis, the total area of the anterior, posterior, lateral and medial cortex sectors was measured and analysed for osteonal parameters including osteon number and density, osteon total and bone area and vascular space area. Osteons were grouped into four classes including cutting heads (A), transversely cut osteons (B), longitudinally cut osteons (C) and sealed osteons (D). The morphometric parameters were compared between the inner (endosteal) and outer (periosteal) half of the cortex. Of 5927 examined osteons, 24.4% cutting heads, 71.1% transversely cut osteons, 2.3% longitudinally cut osteons and 2.2% sealed osteons were found. The interosteonic bone (measured as the area in a lamellar system that has lost contact with its own central canal) corresponded to 51.2% of the endosteal and 52.4% of the periosteal half-cortex. The mean number of class A cutting heads and class B osteons was significantly higher in the periosteal than in the endosteal half-cortex (P < 0.001 and P < 0.05, respectively), whereas there was no significant difference in density. The mean osteon total area, osteon bone area and vascular space area of both classes A and B were significantly higher (P < 0.001 for all three parameters) in the endosteal than in the periosteal half-cortex. The significant differences between the two layers of the cortex suggest that the osteoclast activity is distributed throughout the whole cortical thickness, with more numerous excavations in the external layer, but larger resorption lacunae closer to the marrow canal. A randomly selected population of 109 intact class B osteons was examined at higher magnification (350×) to count osteocyte lacuna and to analyse their relationship with osteon size parameters. The distribution frequency of the mean number of osteocyte lacunae increased with the increment in the sub-classes of osteon bone area, whereas the density did not show significant differences. The number of osteocyte lacunae had a direct correlation with the osteon bone area and the mean osteon wall thickness, as well as the mean number of lamellae. The osteocyte lacunae density showed an inverse relationship. These data suggest a biological regulation of osteoblast activity with a limit to the volume of matrix produced by each cell and proportionality with the number of available cells in the space of the cutting cone (total osteon area). The collected data can be useful as a set of control parameters in healthy human bone for studies on bone aging and metabolic bone diseases.

Do probiotics improve eradication response to Helicobacter pylori on standard triple or sequential therapy?

BACKGROUND: The standard triple therapy for the eradication of Helicobacter pylori consists of a combination of a proton pump inhibitor at a standard dose together with two antibiotics (amoxicillin 1000 mg plus either clarithromycin 500 mg or metronidazole 400 mg) all given twice daily for a period of 7-14 days. Recent reports have shown a dramatic decline in the rate of H. pylori eradication utilizing standard triple therapy from 95% down to 70-80%. AIMS: Our study was designed to evaluate the effect of adding a probiotic as an adjuvant to common regimens used for H. pylori eradication. MATERIALS AND METHODS: An open label randomized observational clinical study was designed to test three different regimens of H. pylori eradication treatment: Standard triple therapy with a concomitant probiotic added at the same time (n = 100), starting the probiotic for 2 weeks before initiating standard triple therapy along with the probiotic (n = 95), and the third regimen consists of the probiotic given concomitantly to sequential treatment (n = 76). The three arms were compared to a control group of patients treated with the traditional standard triple therapy (n = 106). RESULTS: The eradication rate for the traditional standard therapy was 68.9%, and adding the probiotic "Bifidus infantis" to triple therapy, led to a successful rate of eradication of 83% (P < 0.001). Pre-treatment with 2 weeks of B. infantis before adding it to standard triple therapy increased the success rate of eradication to 90.5%. Similar improvement in eradication rate was noted when B. infantis was added as an adjuvant to the sequential therapy leading to an eradication rate of 90.8%. CONCLUSION: Adding B. infantis as an adjuvant to several therapeutic regimens commonly used for the eradication of H. pylori infection significantly improves the cure rates.
