Cytogenetic Estimation of Broccoli Extract on Dexamethasone Treated Mice

The current study was intended to evaluate the active compounds found in hydro-alcoholic extract of Brassica oleracea var. italica(broccoli), also to estimates the percentage of chromosomal aberrations (CAs) ,mitotic index (MI) and micronuclei (MN) formation in mouse bone marrow cells .The mice were divided into, negative group received (0.2 ml of  Distilled Water)intraperitoneally ,positive group I was given single dose of dexamethasone (0.4 mg/kg for 24 h) and positive group II (acute toxicity assay) administrated with (0.2 ml) of  high level dose (800 mg/kg) of extract for 5 days. Interaction groups treated with  different doses of extract (50,100,200,400 and 600 mg/kg) for 5 days in addition to a single ( 0.4 mg/kg) of dexamethasone per each dose of extract. High level dose (800mg/kg) of broccoli extract had show null genotoxicity for bone marrow cells of mouse. Dexamethasone showed significant effects (P< 0.05)  in reducing mitotic index and increased chromosomal aberrations and micronuclei  in mouse bone marrow cells (in vivo). Broccoli extract significantly increased MI and reduced (CA ,MN) (P< 0.05) especially at does (400 mg/kg). Keywords- mitotic index, Micronuclei formation ,Chromosomal aberrations , Dexamethasone, Brassica oleracea var. italica (broccoli), hydro-alcoholic extract

Serum Hepcidin Hormone Level and Its Genes Polymorphism

This chapter sheds light on hepcidin, historical view of hepcidin, and the time of its discovery in the first section. Then this chapter gives information about the genetic aspect and the importance of gene knowledge of hepcidin in explaining many disorders in human beings, supported by illustration figures. The regulation of iron in the human body as an essential function of hepcidin is discussed in this chapter. Examples of the genes of hepcidin (HAMP and HFE) are highlighted in detail as they are essential in regulating iron as well as discussing the genetic mutations that occur in these genes and their medical and clinical impacts for many diseases such as thalassemia. Finally, the inherited disorders related to hepcidin that lead to genetic diseases are discussed

Point prevalence survey of antimicrobial use and resistance during the COVID-19 era among hospitals in Saudi Arabia and the implications

The inappropriate prescribing of antimicrobials increases antimicrobial resistance (AMR), which poses an appreciable threat to public health, increasing morbidity and mortality. Inappropriate antimicrobial prescribing includes their prescribing in patients hospitalized with COVID-19, despite limited evidence of bacterial infections or coinfections. Knowledge of current antimicrobial utilization in Saudi Arabia is currently limited. Consequently, the objective of this study was to document current antimicrobial prescribing patterns among Saudi hospitals during the COVID-19 pandemic. This study included patients with or without COVID-19 who were admitted to five hospitals in Makkah, Saudi Arabia. Data were gathered using the Global PPS methodology and analyzed using descriptive statistics. Out of 897 hospitalized patients, 518 were treated with antibiotics (57.7%), with an average of 1.9 antibiotics per patient. There were 174 culture reports collected, representing 36.5% of all cases. The most common indication for antibiotics use was community-acquired infections, accounting for 61.4% of all cases. ‘Watch’ antibiotics were the most commonly prescribed antibiotics, with the cephalosporins and carbapenems representing 38.7% of all antibiotics prescribed, followed by the penicillins (23.2%). Notably, Piperacillin/Tazobactam and Azithromycin were prescribed at relatively higher rates for COVID-19 patients. These findings highlight the need for continuous efforts to optimize the rational use of antibiotics through instigating appropriate antimicrobial stewardship programs in hospitals and, as a result, reduce AMR in the country

Hepcidin

The hepcidin is antimicrobial peptide has antimicrobial effects discover before more than a thousand years; it has a great role in iron metabolism and innate immunity. Hepcidin is a regulator of iron homeostasis. Its production is increased by iron excess and inflammation and decreased by hypoxia and anemia. Iron-loading anemias are diseases in which hepcidin is controlled by ineffective erythropoiesis and concurrent iron overload impacts. Hepcidin reacts with ferroportin. The ferroportin is found in spleen, duodenum, placenta, if the ferroportin decrease, it results in the reduced iron intake and macrophage release of iron, and using the iron which stores in the liver. Gene of human hepcidin is carried out by chromosome 19q13.1. It consists of (2637) nucleated base. HAMP gene was founded in the liver cells, in brain, trachea, heart, tonsils, and lung. Changing in the HAMP gene will produce a change in hepcidin function. The hepcidin is made many stimulators are included opposing effects exerted by pathological and physiological conditions. Hepcidin is essential for iron metabolism, understanding stricter and genetic base of hepcidin is crucial step to know iron behavior and reactions to many health statuses

The role of neopterin as macrophage activation and C-Reative protein in disease prognosis of coronavirus disease-2019 patients

Coronavirus disease 2019 (COVID 19) has the potential to affect several organs owing to viral-induced hyper inflammation. Hyper inflammation is linked to the severity of coronavirus disease 2019. In severe COVID-19 patients, high levels of circulating cytokines have been recorded. High levels of circulating cytokines were reported in severe COVID-19 patients. Based on current knowledge, the “cytokine storm” appears as one of the most dangerous and potentially life-threatening events related to COVID-19 sustaining its major clinical consequences. Macrophage activation syndrome and its possible contribution to COVID-19, and cytokine targeted attempts in determine severity COVID-19 cases. Serum levels of the immune activation marker neopterin has shown to be of prognostic value in patients with SARS. Release of this cytokines is followed by rapid development of lung tissue damage resulting in acute respiratory distress syndrome, sepsis, and organ failure. In this study, it was aimed the role of macrophage activation in immune response of covid 19 & progressive of disease to determine the prognostic Neopterin levels as prediction of severe disease in patients with COVID‐19. Severe, moderate and mild cases of COVID-19 were compared in terms of clinical and laboratory findings at hospital admission.&nbsp

Human Development Index and its association with staff spiritual care provision: a Middle Eastern oncology study

BackgroundAlthough staff spiritual care provision plays a key role in patient-centered care, there is insufficient information on international variance in attitudes toward spiritual care and its actual provision.MethodsA cross-sectional survey of the attitudes of Middle Eastern oncology physicians and nurses toward eight examples of staff provision of spiritual care: two questionnaire items concerned prayer, while six items related to applied information gathering, such as spiritual history taking, referrals, and encouraging patients in their spirituality. In addition, respondents reported on spiritual care provision for their last three advanced cancer patients.ResultsSeven hundred seventy responses were received from 14 countries (25% from countries with very high Human Development Index (HDI), 41% high, 29% medium, 5% low). Over 63% of respondents positively viewed the six applied information gathering items, while significantly more, over 76%, did so among respondents from very high HDI countries (p value range, p<0.001 to p=0.01). Even though only 42-45% overall were positively inclined toward praying with patients, respondents in lower HDI countries expressed more positive views (p<0.001). In interaction analysis, HDI proved to be the single strongest factor associated with five of eight spiritual care examples (p<0.001 for all). Significantly, the Middle Eastern respondents in our study actually provided actual spiritual care to 47% of their most recent advanced cancer patients, compared to only 27% in a parallel American study, with the key difference identified being HDI.ConclusionsA country's development level is a key factor influencing attitudes toward spiritual care and its actual provision. Respondents from lower ranking HDI countries proved relatively more likely to provide spiritual care and to have positive attitudes toward praying with patients. In contrast, respondents from countries with higher HDI levels had relatively more positive attitudes toward spiritual care interventions that involved gathering information applicable to patient care
