A genetic variant c.553G > T (rs2075291) in the apolipoprotein A5 gene is associated with altered triglycerides levels in coronary artery disease (CAD) patients with lipid lowering drug

Background: Elevated plasma triglycerides (TGs) are widely used as a major cardiovascular risk predictor and are thought to play an important role in the progression of coronary heart disease (CHD). It has been demonstrated that lipid lowering was associated with lower mortality in patients with CHD. The present study therefore aimed to investigate the consequences of the genetic variant c.553G>T (rs2075291) in apolipoprotein A5 gene to determination of triglycerides levels in CAD patients receiving, atorvastatin, lipid lowering drug. Methods: We here report that a recently identified genetic variant, c.553G>T in the APOA5 gene which causes a substitution of a cysteine for a glycine residue at amino acid residue 185(G185C) is also associated with increased TG levels. To investigate theses effects, a case-control study compressing 608 subjects from the same area was performed.ResultsTG levels in T allele patients were significantly lower than the control GT allele patient ((2)=2.382E2(a), P-value T variant (rs2075291); in APOA5 gene increases human plasma TG levels. Conclusion: Nevertheless, T allele is found to reduce TG levels in CAD patients who are on the cholesterol medication, atorvastatin. Thus, c.553G>T variant can be considered as a significant predicator of hypertriglyceridemia. In addition, it could be used as a hallmark for the diagnosis and prognosis of CAD

Erratum: Global, regional, and national comparative risk assessment of 84 behavioural, environmental and occupational, and metabolic risks or clusters of risks for 195 countries and territories, 1990–2017: a systematic analysis for the Global Burden of Disease Study 2017

Interpretation: By quantifying levels and trends in exposures to risk factors and the resulting disease burden, this assessment offers insight into where past policy and programme efforts might have been successful and highlights current priorities for public health action. Decreases in behavioural, environmental, and occupational risks have largely offset the effects of population growth and ageing, in relation to trends in absolute burden. Conversely, the combination of increasing metabolic risks and population ageing will probably continue to drive the increasing trends in non-communicable diseases at the global level, which presents both a public health challenge and opportunity. We see considerable spatiotemporal heterogeneity in levels of risk exposure and risk-attributable burden. Although levels of development underlie some of this heterogeneity, O/E ratios show risks for which countries are overperforming or underperforming relative to their level of development. As such, these ratios provide a benchmarking tool to help to focus local decision making. Our findings reinforce the importance of both risk exposure monitoring and epidemiological research to assess causal connections between risks and health outcomes, and they highlight the usefulness of the GBD study in synthesising data to draw comprehensive and robust conclusions that help to inform good policy and strategic health planning

Whole-genome sequencing reveals host factors underlying critical COVID-19

Critical COVID-19 is caused by immune-mediated inflammatory lung injury. Host genetic variation influences the development of illness requiring critical care1 or hospitalization2,3,4 after infection with SARS-CoV-2. The GenOMICC (Genetics of Mortality in Critical Care) study enables the comparison of genomes from individuals who are critically ill with those of population controls to find underlying disease mechanisms. Here we use whole-genome sequencing in 7,491 critically ill individuals compared with 48,400 controls to discover and replicate 23 independent variants that significantly predispose to critical COVID-19. We identify 16 new independent associations, including variants within genes that are involved in interferon signalling (IL10RB and PLSCR1), leucocyte differentiation (BCL11A) and blood-type antigen secretor status (FUT2). Using transcriptome-wide association and colocalization to infer the effect of gene expression on disease severity, we find evidence that implicates multiple genes—including reduced expression of a membrane flippase (ATP11A), and increased expression of a mucin (MUC1)—in critical disease. Mendelian randomization provides evidence in support of causal roles for myeloid cell adhesion molecules (SELE, ICAM5 and CD209) and the coagulation factor F8, all of which are potentially druggable targets. Our results are broadly consistent with a multi-component model of COVID-19 pathophysiology, in which at least two distinct mechanisms can predispose to life-threatening disease: failure to control viral replication; or an enhanced tendency towards pulmonary inflammation and intravascular coagulation. We show that comparison between cases of critical illness and population controls is highly efficient for the detection of therapeutically relevant mechanisms of disease

Chickpea (Cicer arietinum) steep liquor as a leavening agent: Effect on dough rheology and sensory properties of bread

Dough fermentation is one of the oldest process in food technologies. It has been recently intensively studied for its impact on the sensory, structural, nutritional and shelf life properties of leavened baked products. The goals of this work were to investigate chickpea steep liquor (CSL) as a dough-leavening agent and to study the effect of CSL on the dough rheology and sensory properties of leavened bread. CSL was prepared by submerging chickpea seeds in boiled distilled water (1:2, w/v) for 24 h at 37оC, and then obtained liquor was filtered and freeze-dried to obtain CSL. The addition of CSL to wheat flour (WF) brought changes in the dough mixing behavior as measured by the farinograph. An increase in the farinograph water absorption of WF dough was observed when 4.5% CSL and 1.5% yeast was added, while arrival time was not affected. Addition of CSL to the dough at a content of 4.5, 9.0 and 13.5 g CSL/300 g WF caused an increase in dough stability. The CSL addition also increased mechanical tolerance index, dough weakening and mixing time. Dough development time for all blends was higher than the control (1.2-1.5 min), while between the CSL samples no significant difference was observed. The loaf weight slightly increased from 146.2 g for control to 152.2 g for CSL fermented bread, whereas the loaf volume and specific volume of CSL-fermented bread were lower than the control. The combination of yeast and CSL increased the acceptability of bread with the increasing level of both leavening agents’. The results show that CSL could be used as an alternative to yeast for syngas fermentation. On the other hand, CLS is rich in nutrients and lower in cost compared to yeast

Prognostic

Background: Significant portions of central airway stenosis patients present with unresectable disease. Using bronchotherapeutic procedures to maintain a patent airway and improve clinical symptoms and quality of life is a well-known armamentarium technique. Aim: To assess the contribution of different physiological and pathological prognostic factors on the yield of endobronchial therapies (argon plasma coagulation (APC) and electrocautery) in patients with central airway obstruction whether derived from malignant or non-malignant etiology. Patients and methods: Twenty nine patients with central airway obstruction, 21 males and eight females, were recruited in the study. All the studied patients were categorized into malignant and non-malignant groups with different pathological varieties. Interventional bronchoscopic procedures were performed under general anesthesia. The flexible bronchoscope was either passed via an endotracheal tube or through the rigid bronchoscope. Collected data included patient demographics, evaluation of performance scale and quality of life status, evaluation of dyspnea, cough and hemoptysis scores before the interventional bronchoscopy and 1 day after the last session. Also the collected data included; length, size, localization and bronchoscopic appearance of the lesion. Duration of symptoms, duration of mechanical ventilation and the presence of collapse prior to the intervention were all recorded. Number of sessions and type of bronchoscopic modalities used were recorded. Spirometric pulmonary function tests were done before and 1 day after the last session. Results: Complete recanalization was achieved in (17/29) 58.6% of patients, while incomplete or partial recanalization was achieved in (12/29) 41.4% of patients. Using linear regression analysis of independent factors affecting patient outcome; it was found that the length of lesion followed by presence of collapse, duration of symptoms and lastly lesion localization whether localized or diffuse (P < 0.0005), (P < 0.011), (P < 0.02) and (P < 0.039) were the most independent factors affecting patient outcome. Conclusion: For favorable outcome, selection of patients with central airway obstructing lesions candidates for bronchoscopic argon plasma coagulation and/or electrocautery should rely on several factors including; age, duration of symptoms, performance scale, co-morbidities, pre-therapeutic FEV1%, presence of lung collapse, and length of the obstructing lesion, moreover its shape and localization
