Systemic Review and Clinical Management in Diagnosis and Treatment of the Iron Deficiency Anemia in Adults

This study aimed at exploring with a systematic review the clinical management in diagnosis and treatment of the iron deficiency anemia in adults, as the iron deficiency is the most frequent cause of anemia worldwide. And it impairs quality of life, increases asthenia and can lead to clinical worsening of patients. In addition, iron deficiency has a complex mechanism whose pathologic pathway is recently becoming better understood. This review summarizes the current knowledge regarding diagnostic algorithms for iron deficiency anemia. The majority of aetiologies occur in the digestive tract, and justify morphological examination of the gut. First line investigations are upper gastrointestinal endoscopy and colonoscopy, and when negative, the small bowel should be explored; newer tools such as video capsule endoscopy have also been developed. The treatment of iron deficiency is aetiological if possible and iron supplementation whether in oral or in parenteral form

Fracture Classification Associated with the Orthopaedic Trauma

This study aimed at exploring the fracture classification associated with the orthopaedic trauma as the provision of care associated with orthopedic trauma shares an important goal, which is to restore and preserve function. A focused assessment that embodies subjective and objective data will assist the healthcare professional to determine a patient’s needs and deliver the most appropriate level of care. Learning to collect data about factors associated with an orthopedic injury is an integral part of providing care for individuals who have sustained an orthopedic trauma. Fracture classification is the categorization of a fracture. It is used for documentation and research and gives surgeons and patients information about treatment options and prognosis. The process of obtaining this documentation is the process of diagnosis

Hand hygiene knowledge and attitude of medical students in western Saudi Arabia

Background The practice of hand hygiene (HH) has prime importance among Health Care Professionals (HCPs) and non-compliance could cause adverse consequences. By keeping the importance of HH in mind, this study aims at investigating the knowledge and attitudes towards HH among medical students and interns at King Abdulaziz University (KAU), Jeddah, Saudi Arabia (SA). Methods The study includes 453 medical students and interns (189 males & 264 females). This study was completed in three months; from September to November 2017. The World Health Organization (WHO) HH questionnaire was used and data were analyzed on SPSS-21. Results Two-third of the participants 292 (64.2%) had formal training in HH in the last three years. Almost half of the participants 254 (56.1%) had correct knowledge regarding the major course of transmission of potentially detrimental microbes among patients in the healthcare premises. Just 124 (27.4%) of the respondents had the correct knowledge about the most common basis of germs accountable for healthcare-related infections. Females had significantly better knowledge than males regarding the type of HH technique needed before palpation of the abdomen (177(54%) Vs. 151(46%); P < 0.002), before an injection (175(54.5%) Vs. 146(45.5%); P < 0.007), after emptying a bedpan (207(64.7%) Vs. 113(35.3%); P < 0.001), following discarding examination gloves (256(60.4% Vs. 168(39.6%); P < 0.001] and after exposure to blood (200(64.1%) Vs. 112(35.%); P < 0.001). Female participants had better knowledge than males regarding the type of HH actions. Females also had a significantly better attitude towards the importance of HH than males (240(62.5%) Vs. 144(37.5%); P < 0.001). Conclusion The majority of the participants’ knowledge regarding HH was not up to the mark; however, female students had better knowledge compared to male students. The medical students and interns’ knowledge and positive attitude towards HH can play a pivotal role in preventing HCPs associated infections and it would overall decrease the infection-related burden on the hospital and governmental budgets. It is suggested that multi-dimensional plans are required to change this low compliance to a higher rate

Mitochondrial Succinate Metabolism and Reactive Oxygen Species Are Important but Not Essential for Eliciting Carotid Body and Ventilatory Responses to Hypoxia in the Rat

From MDPI via Jisc Publications RouterHistory: accepted 2021-05-21, pub-electronic 2021-05-25Publication status: PublishedFunder: Wellcome Trust; Grant(s): Institutional Strategic Support Fund AwardFunder: Umm Al-Qura University (Makkah, Saudi Arabia); Grant(s): PhD Scholarship, PhD ScholarshipReflex increases in breathing in response to acute hypoxia are dependent on activation of the carotid body (CB)—A specialised peripheral chemoreceptor. Central to CB O2-sensing is their unique mitochondria but the link between mitochondrial inhibition and cellular stimulation is unresolved. The objective of this study was to evaluate if ex vivo intact CB nerve activity and in vivo whole body ventilatory responses to hypoxia were modified by alterations in succinate metabolism and mitochondrial ROS (mitoROS) generation in the rat. Application of diethyl succinate (DESucc) caused concentration-dependent increases in chemoafferent frequency measuring approximately 10–30% of that induced by severe hypoxia. Inhibition of mitochondrial succinate metabolism by dimethyl malonate (DMM) evoked basal excitation and attenuated the rise in chemoafferent activity in hypoxia. However, approximately 50% of the response to hypoxia was preserved. MitoTEMPO (MitoT) and 10-(6′-plastoquinonyl) decyltriphenylphosphonium (SKQ1) (mitochondrial antioxidants) decreased chemoafferent activity in hypoxia by approximately 20–50%. In awake animals, MitoT and SKQ1 attenuated the rise in respiratory frequency during hypoxia, and SKQ1 also significantly blunted the overall hypoxic ventilatory response (HVR) by approximately 20%. Thus, whilst the data support a role for succinate and mitoROS in CB and whole body O2-sensing in the rat, they are not the sole mediators. Treatment of the CB with mitochondrial selective antioxidants may offer a new approach for treating CB-related cardiovascular–respiratory disorders

Association Between Lipid Profile and Diabetic Foot Ulcer

Diabetic foot ulcer is a serious disabling consequence of Diabetes Mellitus. They are characterized by the breakdown of skin and underlying tissues in the feet, and are a major cause of lower limb amputations. Various risk factors have been identified for the development of diabetic foot ulcers, including poor glycemic control, peripheral neuropathy, peripheral arterial disease, and impaired wound healing. it is considered that the lipid profile is one of many factors that contribute to the formation and progression of diabetic foot ulcers. To stratify the incidence of diabetic foot ulcers (DFUs), biomarkers are required. The aim of this review is to assess the relationship between the risk of DFU and lipid profile in diabetic patients

The effect of mephedrone on human neuroblastoma and astrocytoma cells

Mephedrone is an illegal drug that is used recreationally. Few studies have been conducted to investigate the mechanisms by which mephedrone is harming cells. In this research, we investigated the effect of mephedrone using toxicology coupled with LC-MS/MS based metabolomics in the two CNS derived cell lines. Methods of assessment such as neutral red (NR) assay, dimethylthiazolyl diphenyltetrazolium bromide (MTT), lactose dehydrogenase (LDH) measurement, and morphology were performed to identify the effect on cell viability and to identify the best concentration to be used in a metabolomics study. A concentration of 100 μM of mephedrone was used in the metabolomic experiment because at this concentration mephedrone had induced several intracellular changes. Although there no clear indicators of cellular damage caused by mephedrone. In astrocytes there was a clear indication that cell membrane function might be impaired by depletion of ether lipids

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
