Neuropeptide substance P alters stem cell fate to aid wound healing and promote epidermal stratification through asymmetric stem cell divisions.

Loss of sensory innervation delays wound healing and administration of the neuropeptide substance P improves re-epithelialization. Keratinocyte hyperproliferation post-wounding may result from symmetric stem cell (SC) self-renewal, asymmetric SC self-renewal, committed progenitor divisions, or a combination of these. However, the effects of sensory denervation and of neuropeptides on SC proliferation are not known. Here we show that early after wounding both asymmetric and symmetric SC self-renewal increase, without significant committed progenitor (CP) activation. Decreased sensory innervation is associated with a decrease in both SC and CP proliferation. Based on previous work showing that substance P is decreased in capsaicin-treated mice and improves wound healing in normal skin, we examined the effects of substance P on SC and CP proliferation during wound healing. Substance P restored asymmetric SC proliferation in skin with decreased sensory innervation, both at baseline and following wounding. Epidermis with decreased sensory innervation was severely thinned. Consistent with this, substance P-induced asymmetric SC proliferation resulted in increased stratification in skin with both normal and decreased innervation. Lapatinib prevented the substance P-induced increase in asymmetric SC divisions in murine epidermis, as well as the increase in epidermal stratification, suggesting that asymmetric SC divisions are required for epidermal stratification.

Development of an intraoperative 3D C-arm technique for torsion control of femur fractures: a cadaver study.

AIM: This study aims to test the accuracy and feasibility of a measurement of femoral torsion of a 3D C-arm system (Linea aspera method) in a cadaver setting. MATERIALS AND METHODS: A total of 11 intact femora were used. Schanz screws were inserted in the femoral bone in a parallel manner with the help of a fixed drill sleeve. Femur bones were then fractured in a controlled manner and three different internal and external torsion angles were fixed with the help of a Goniometer. After that, a 3D scan was performed. The 3D data set was analyzed using a radiologic software (Visage 7, Visage Imaging Inc, USA). Measurements were then compared in the two methods with a dependent t test. RESULTS: Specific measurements for different angles did not show any differences between those two utilities. CONCLUSION: Intraoperative estimation of femoral antetorsion using a 3D C-Arm system and the Linea aspera method seems to be an accurate and feasible method. Nevertheless, more studies with higher patient numbers, comparison to CT seems to be the next step and can be recommended.

[Acute on chronic renal failure in a 62-year-old man with ANCA-associated vasculitis]. / Neue Nierenfunktionsverschlechterung bei einem 62-jährigen Patienten mit ANCA-assoziierter Vaskulitis.

We describe a patient with ANCA (antineutrophil cytoplasmic antibodies) associated vasculitis and acute-on-chronic renal failure. He had initially presented with severe pulmonary hemorrhage and anuric renal failure and improved rapidly with immunosuppressive therapy. Repeat renal biopsy revealed candida interstitial nephritis. Candida was also detected in bronchoalveolar lavage. Kidney function improved with long-term antifungal therapy. This report adds induction therapy for ANCA vasculitis to the conditions where invasive candidal infections including nephritis need to be considered.

The burden and epidemiology of community-acquired central nervous system infections: a multinational study.

Risk assessment of central nervous system (CNS) infection patients is of key importance in predicting likely pathogens. However, data are lacking on the epidemiology globally. We performed a multicenter study to understand the burden of community-acquired CNS (CA-CNS) infections between 2012 and 2014. A total of 2583 patients with CA-CNS infections were included from 37 referral centers in 20 countries. Of these, 477 (18.5%) patients survived with sequelae and 227 (8.8%) died, and 1879 (72.7%) patients were discharged with complete cure. The most frequent infecting pathogens in this study were Streptococcus pneumoniae (n = 206, 8%) and Mycobacterium tuberculosis (n = 152, 5.9%). Varicella zoster virus and Listeria were other common pathogens in the elderly. Although staphylococci and Listeria resulted in frequent infections in immunocompromised patients, cryptococci were leading pathogens in human immunodeficiency virus (HIV)-positive individuals. Among the patients with any proven etiology, 96 (8.9%) patients presented with clinical features of a chronic CNS disease. Neurosyphilis, neurobrucellosis, neuroborreliosis, and CNS tuberculosis had a predilection to present chronic courses. Listeria monocytogenes, Staphylococcus aureus, M. tuberculosis, and S. pneumoniae were the most fatal forms, while sequelae were significantly higher for herpes simplex virus type 1 (p < 0.05 for all). Tackling the high burden of CNS infections globally can only be achieved with effective pneumococcal immunization and strategies to eliminate tuberculosis, and more must be done to improve diagnostic capacity.

Lithography-free wide-angle antireflective self-cleaning silicon nanocones.

Low-cost, wideband, and wide-angle antireflective layers are of prime importance to photovoltaic and other optoelectronic applications. We report a novel fabrication methodology of random textured silicon nanocones (SiNCs) array through metal-assisted chemical etching combined with oxidation. The optical properties of the fabricated structure are studied theoretically and experimentally. The random textured SiNCs array showed very promising broadband antireflective properties through the entire visible wavelength range at different incident angles up to ±60°. In addition, the nanostructures inherently could become self-cleaning due to the high contact angle. This random cheap textured SiNCs array increases the absorption efficiency of photodetectors and reduces its cost.

Laparoscopic common bile duct exploration.

BACKGROUND: Laparoscopic common bile duct exploration (LCBDE) is a safe and effective single-stage treatment for choledocholithiasis in the elective setting. The outcomes after LCBDE in the emergency setting are unknown. The aim of this study was to compare the outcomes following elective and emergency LCBDE for choledocholithiasis. METHODS: Details of all patients who underwent LCBDE for choledocholithiasis between August 2003 and August 2013 were analysed retrospectively. The primary outcome measure was common bile duct (CBD) stone clearance rate. Secondary outcome measures were conversion rate, morbidity, mortality and length of hospital stay. RESULTS: Some 215 consecutive patients (57 male; median age 65 (range 14-92) years) underwent LCBDE. Some 121 procedures were performed electively and 94 as an emergency. Forty-five patients (48 per cent) presented with obstructive jaundice or cholangitis in the emergency LCBDE group compared with 15 (12·4 per cent) in the elective group (P < 0·001). The CBD stone clearance rate was similarly high in both groups (96 versus 96·7 per cent respectively; P = 0·557). There were no significant differences in conversion rate (6 versus 4·1 per cent), morbidity (5 versus 6·6 per cent), mortality (2 versus 0 per cent) or median length of stay (3 days) between groups. Two patients died, both following emergency LCBDE. CONCLUSION: LCBDE can be performed safely and effectively in both elective and emergency settings.

Lessons learned from Jordan's response to the Syria refugee crisis.

The number of refugees across the world has jumped from 15.7 million to 34.6 million in the past 10 years, and their forced displacement situation remain for an average period of 20 years. To ensure sustainable benefits, health system strengthening through development cooperation should be a priority in parallel to humanitarian aid early on in refugee crises.

Predictors of quality of life among multiple sclerosis patients: a comprehensive analysis.

BACKGROUND AND PURPOSE: Multiple sclerosis (MS) is a debilitating neurological disease of young people with substantial consequences on patients' quality of life (QOL). A variety of QOL instruments have been used to evaluate the efficacy of treatments. However, no study assessed the role of the different demographic, clinical, physical, social, economic and psychological parameters in the perception of patients with MS of their QOL. METHODS: Two-hundred and one consecutive patients attending outpatient clinics were prospectively studied and objectively assessed using Expanded Disability Status Scale (EDSS), 8-m walk test, and Symbol Digit Modality Test. Patients completed the following questionnaires: MS QOL-54, Hamilton Depression Rating Scale, Fatigue Severity Scale, Brief Pain Inventory Average Pain Score, Drug Side-Effects Severity Scale, Social Support, Religiosity, Physiotherapy and Exercise, and Socioeconomic Profile. Overall, QOL, physical (PHCS) and mental (MHCS) health composite scores were computed as outcome measures from MSQOL-54. RESULTS: Depression, social support, religiosity, education years and living area predicted overall QOL by linear regression (R(2) = 0.43). Unemployment and absence of fatigue correlated with poor and good QOL, respectively. Fatigue, pain, depression, EDSS, social support, MS type and anti-cholinergic treatment predicted PHCS (R(2) = 0.81). Fatigue, pain, depression, education years and social support predicted MHCS (R(2) = 0.70). CONCLUSION: The QOL in patients with MS is not solely determined by physical disability, but rather by the level of social support, living area, depression, level of education, employment, fatigue and religiosity. Accordingly, we suggest that these should be evaluated in every patient with MS as they may be modified by targeted interventions.

Genicular nerve block in juvenile idiopathic arthritis: a randomized clinical trial.

OBJECTIVES: This study aimed at evaluating the effect of genicular nerve block (GNB) in juvenile idiopathic arthritis (JIA) patients with persistent unilateral knee arthritis on pain, inflammatory parameters, function, and range of motion. METHODS: A total of 104 JIA patients were diagnosed according to the International League Against Rheumatism (ILAR) criteria with persistent unilateral knee arthritis. They were allocated randomly into 2 groups: group 1 treated with GNB, while group 2 was treated with intra-articular triamcinolone (TA) only. Visual analogue scale (VAS) on pain, sonography of large joints in rheumatology (SOLAR) scoring system, and Lysholm scores were assessed at 0-, 2-, and 12-week intervals. Swelling and tenderness were clinically evaluated semi-quantitatively (0-3) at the same time intervals. RESULTS: VAS pain, tenderness, swelling, and SOLAR grey scale (GS) and power Doppler (PD) scores were significantly reduced after 2 weeks in both groups (p < 0.05). This was greater in the GNB group regarding VAS and tenderness, while SOLAR and swelling were stronger reduced in TA group. After 12 weeks, all outcome measures showed lower values in the GNB group compared to TA, and this was significant regarding VAS pain. Moreover, Lysholm functional score was significantly increased in both groups at both intervals; and higher values were seen in the TA group compared to GNB after 2 weeks. CONCLUSION: GNB was able to control pain and improve function and inflammation of the knee joint in JIA patients. Though steroid attained better results after 2 weeks, GNB achieved an equivalent longer-term improvement after 12 weeks. TRIAL REGISTRATION IDENTIFYING NUMBER: NCT04687930. Key Points • Persistent knee arthritis treatment in JIA is always challenging. • GNB was approved for treatment of pain in knee osteoarthritis. • GNB in the present study succeeded to control active knee arthritis and this effect was comparable to intra-articular steroid injection.

Control and treatment of type 2 diabetes in private patients in the Egyptian "DIACONTROL study".

OBJECTIVE: This study aims to identify the characteristics of Egyptian patients suffering from type 2 diabetes mellitus (T2DM), determine disease control rates, and gain insights into clinical treatments. PATIENTS AND METHODS: A total of 2,516 patients with T2DM were recruited from 244 private clinics across Egypt in a one-month period from May to June 2017. Data collected from patients included glycemic control parameters of glycosylated hemoglobin, fasting plasma glucose, and postprandial glucose. Additional information gathered included patients' weight, age, level of physical activity, smoking habits, presence of comorbidities, type of treatment received for type 2 diabetes, number and severity of hypoglycemic events, as well as treatment modification by the physician in the last visit. The type of statistics used for the analysis is descriptive statistics and regression model. RESULTS: Only 18.4% of participating patients achieved the target level of glycosylated hemoglobin of 7% or below. The mean age of these patients was 54±11.2 years, and the mean duration since the first diagnosis was 6.6±6.4 years. A total of 33.4% of all patients had no known comorbidity, while the rest had one or more known and treated comorbidities. A total of 76% of patients received sulfonylurea either as monotherapy or in combination with other treatments. In addition, no treatment modifications or adjustments were provided for 32% of the study participants who did not reach their glycemic control target. CONCLUSIONS: In Egypt, there is a low rate of glycemic control among private patients and a high prevalence of comorbid conditions. This is likely to cause a significant health burden to people with T2DM, the healthcare system, and the economy due to a loss in productivity. This study presented an argument for better-managed measures to improve glycemic control in the population, such as patient education to increase patient awareness and adherence to treatment protocols as well as improved adherence to guidelines by clinicians.

Glioblastoma with Primitive Neuroectodermal Tumor like Component: Rare and Enigmatic.

Glioblastoma (GBM) with Primitive Neuroectodermal tumor (PNET) like features is an extremely rare tumor showing dual features of malignant glioma and primitive neuroectodermal tumour occurring mostly in adults. It poses diagnostics dilemma to the neuropathologist and treating oncologist team because of its rarity, tendency to spread to cerebrospinal fluid and dismal prognosis. We have described this tumor in a 11 years old male child in this case report. Keywords: glioma,glioblastoma,primitive neuroectodermal tumor, variant, pediatric.

[Epidemiological study of Klebsiella spp. uropathogenic strains producing extended-spectrum ß-lactamase in a Tunisian university hospital, 2009]. / Epidémiologie des souches de Klebsiella spp. uropathogènes productrices de ß-lactamases à spectre élargi dans un hôpital universitaire Tunisien, 2009.

OBJECTIVE: An update on the prevalence of antibiotic resistance in extended-spectrum ß-lactamase among urinary strains of Klebsiella spp. isolated from in-come and out-come patients at University Hospital, Mahdia (Tunisia). PATIENTS AND METHODS: A retrospective survey was made over a period of twelve months (year 2009). It focused on 3564 patients with urinary tract infection confirmed by the Laboratory of Microbiology in the University Hospital, Mahdia. RESULTS: Klebsiella spp. was involved in 5.5% (198/3564) of all cases of urinary tract infections identified. Klebsiella pneumoniae accounted for 94.9% of all Klebsiella (5.1% for Klebsiella oxytoca). The frequency of Klebsiella spp. resistance to fluoroquinolones was 19.2% and to third generation cephalosporins was 22.7%. Forty strains of Klebsiella spp. producing extended-spectrum ß-lactamase witch corresponds to 20.2% of all the Klebsiella. The extended-spectrum ß-lactamase strains with resistance to fluoroquinolones were 67.5% (27/40) or 13.6% of all klebsiella (27/198). No strain was resistant to imipenem. The 27 strains multiresistant (ESBL+FQ resistance) are likely to be carriers of plasmids encoding the ESBL and resistance to fluoroquinolones. CONCLUSION: the resistance of Enterobacteriaceae, including Klebsiella spp, to fluoroquinolones has become a concern both in hospital in community medicine. The advent of this resistance mechanism involves a more rational use of fluoroquinolones, especially as first-line treatment of urinary tract infections.

Plant growth promoting bacteria drive food security.

The essence of food security centers on ensuring availability and accessibility of foods in adequate amounts and quality for all populations at all times for an active and healthy life. Microorganisms are tiny bioreactors, which represent sustainable resources and promising approaches to bridging the gap between food production and consumption globally via various biotechnological applications. This review focuses on plant-growth promoting bacteria (PGPB) which exert their potential impacts on increasing soil fertility, plant growth, and productivity through a variety of processes, including direct, indirect, and synergistic mechanisms. PGPB plays a substantial role in accelerating nutrients' availability such as (N, P), producing phytohormones such as gibberellins, IAA, and bioactive compounds against biotic and abiotic stressors. Recent advances in PGPB will be addressed as a sustainable approach to satisfy global food demand.

Isolation and characterization of Klebsiella oxytoca from the rhizosphere of Lotus corniculatus and its biostimulating features.

Significant food resource shortages are occurring worldwide. Plant growth-promoting rhizobacteria (PGPR) represent an ecofriendly and efficient approach for increasing soil fertility and plant productivity. The current study explored biostimulating traits of PGPR from the rhizosphere of Lotus corniculatus growing in the Al-Ahsa region. A bacterial isolate (LCK121) was obtained, characterized for phenotypic, and identified by 16S rRNA gene sequencing. In addition, its growth-stimulating effects on barley were investigated. The strain identity was confirmed via comparative analysis of the 16S rDNA sequences with Klebsiella oxytoca (99.3% similarity level). LCK121 exhibited multiple plant growth-promoting features, including indole-3-acetic acid (IAA) production (16.34 µg mL-1), 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase activity (1.35±0.02 µmol α-ketobutyrate mg-1 h-1), phosphate solubilization, and nitrogen fixation. Furthermore, in vitro inoculation of barley with LCK121 significantly increased the root and shoot dry weights. The results highlight the potential of LCK121 for developing green fertilizers for sustainable agriculture.

Spirulina therapeutic potentiality in polycystic ovarian syndrome management using DHEA-induced rat model.

OBJECTIVE: The most prevalent endocrinopathy in women is polycystic ovarian syndrome (PCOS). Multiple gene abnormalities like Ar, Cyp19a1, Hsd3b1, Srd5a1, Bcl-2, and Bax genes are associated with PCOS. Herein, the PCOS model was induced by oral administration of dehydroepiandrosterone (DHEA). Metformin (Met) is one of the most common drugs affecting the most relevant genes involved in PCOS development but with unwanted side effects. Natural treatments have been known for their safer effects. Spirulina (SP) is a type of blue-green algae that contains nutrients and compounds that would treat PCOS and lower the possible side effects of Met in combination therapy. We aim to evaluate the clinical effectiveness and safety of SP on PCOS by multi confirmatory tests and to demonstrate its effects on regulating the expression of multiple genes that are responsible for the occurrence of PCOS in comparison to Met. MATERIALS AND METHODS: Herein, sixty adult female Wistar albino rats were subdivided into equal six groups with 10 rats in each group. All drugs were given orally once daily for one month. The expression of Ar, Cyp19a1, Hsd3b1, Srd5a1, Bcl-2, and Bax genes, were examined by quantitative real-time PCR (qRT-PCR). RESULTS: The present study showed that SP has a remarkable effect on the reduction of the development of PCOS by regulating the expression of the examined genes. As a result, it may be a useful therapy alternative for PCOS complications, symptoms, and infertility as well. CONCLUSIONS: Collectively, SP is considered a promising therapeutic drug in the treatment of PCOS-like symptoms induced by DHEA.

Factors affecting university image among graduate alumni: A case study of Qatar university.

Various factors influence the students' perception of universities and university image. This study explores five factors affecting university image among Graduate Alumni. Surveys, administered to 597 graduate alumni were assessed to determine Graduate Alumni perspectives toward their university. Findings revealed that the key factors that impacted graduate alumni affecting the university's image and reputation were gender, nationality, level of study, and the ability of the institution to equip graduates with certain specific skills. Based on these findings, the university should consider further examining these areas to provide a more in-depth understanding of how these factors work to shape graduate students' perspectives of the university and develop ways to address areas that need to be developed and improved.

Mathematical modeling of aeration efficiency and dissolved oxygen provided by stepped cascade aeration.

Mathematical modeling has been a vital tool in the field of environmental engineering. Various models have been developed to simulate the level of aeration efficiency (AE) provided by different aerating structures to raise levels of dissolved oxygen (DO) in streams; one of which is the stepped cascade structure. Three models developed by Gameson et al. WRL, and Nakasone, in addition to Qual2k, a computer program for stream modeling, have been used in this research; values of AEs obtained have been compared to those computed using DO measured from a built model at a WWTP. A stepped cascade structure was installed with different heights to aerate five flowrates with different levels of COD. An adjustment has been made to the Nakasone model to test the effect of pollutant load on the amount of aeration that could be reached. Values of AEs computed using the Gameson model were 30%, 39.5%, and 40% for cascade heights (H(d)) 45, 60, and 75 cm respectively for the five flowrates (q) that ranged from 21-66 m³/hr. Values of AEs from WRL model were 32.8%, 42%, and 43% consequently. Values of AEs from Nakasone model ranged from 4.6-7.5%, 6-10%, and 7.6-12% respectively. For the adjusted Nakasone model, values of AEs ranged from 3.2-4.9%, 3.3-5.3%, and 4.1-6.7% respectively. Finally, the AEs computed using the values of downstream DO generated by Qual2k ranged from 4-18%, 2-15%, and 2.5-5.1% correspondingly. Around 80% of the downstream DO values computed using the Nakasone and adjusted Nakasone model were closer to those measured in the field, thus more reliable in cascade design.

[Acquired bacterial meningitis in Monastir region, Tunisia (1999-2006): bacteriological aspects and susceptibility patterns]. / Lesméningites purulentes dans la région deMonastir, Tunisie (1999-2006): aspects bactériologiques et état de résistance aux antibiotiques.

The aim of this study was to analyze the distribution of bacteria responsible for purulent meningitis and the pattern of resistance of common species in the University Hospital of Monastir (Tunisia). All bacteriologically confirmed cases of bacterial meningitis were recorded between 1999 and 2006, and have been analyzed by classic bacterial methods advocate for meningitis. Two hundred fifty three strains have been isolated. The most frequent species were Streptococcus pneumoniae, Haemophilus influenzae, and Klebsiella pneumoniae, followed by Escherichia coli and Neisseria meningitides with 19.4, 13.8, 13.8, 7.1, and 6.3% of cases, respectively. Their distribution with regard to age was in accordance with literature data. The yearly distribution of these bacteria did not show any epidemic peak. Enterobacteriaceae and group B Streptococcus were the most frequently identified pathogens in neonatal meningitis. H. Influenzae was the predominant microorganism in children between three month and five years of age (36.3%), followed by S. Pneumoniae (28.8%). S. Pneumoniae was the predominant bacteria responsible for 47% of the cases over five years of age. 38.8% of S. Pneumoniae strains were less susceptible to penicillin. Resistance rates for amoxicillin and cefotaxime were 4.1%, respectively. Only one strain of N. meningitidis (6.2%) presented a decreased susceptibility to penicillin. 22.9% of H. Influenzae strains produced ß-lactamase. The resistance rates of Enterobacteriaceae to third generation cephalosporins were 25%. In our study, nosocomial meningitis have shown a rate of 24.4%. The most affected service was neurosurgery, pediatrics, and intensive care units. The increasing prevalence of pneumococci meningitis with reduced sensitivity to penicillin G strains isolated from meningitis makes adequate therapeutic management difficult.

In vitro antibacterial activities of silver nanoparticles synthesised using the seed extracts of three varieties of Phoenix dactylifera.

Green synthesis of silver nanoparticles (AgNPs) is an ecofriendly, cost-effective and promising approach for discovery of novel therapeutics. The aim of the current work was to biogenic synthesize, characterize AgNPs using seed extracts of three economically important varieties of date palm (Iklas, Irziz and Shishi), and assess their anti-pathogenic bacterial activities. AgNPs were synthesised then characterised using electron microscopy and Fourier transform infrared analyses. The bactericidal activities of AgNPs against five different bacterial pathogens, Bacillus subtilis, Escherichia coli, Staphylococcus aureus, methicillin-resistant Staphylococcus aureus and Streptococcus pneumoniae, were determined in vitro. In particular, changes in membrane integrity of virulent bacterial strains in response to AgNPs were investigated. Results of lactate dehydrogenase, alkaline phosphatase activity assays, and measurement of membrane potential revealed that the cytotoxic effects of the AgNPs were mainly centred on the plasma membrane of bacterial cells, leading to loss of its integrity and eventually cell death. In conclusion, green synthesis of AgNPs is an efficient, cost-effective and promising strategy to combat virulent antibiotic-resistant strains.

Risk factors, predictions, and progression of acute kidney injury in hospitalized COVID-19 patients: An observational retrospective cohort study.

OBJECTIVES: Studies have shown that acute kidney injury (AKI) occurrence post SARS-CoV-2 infection is complex and has a poor prognosis. Therefore, more studies are needed to understand the rate and the predications of AKI involvement among hospitalized COVID-19 patients and AKI's impact on prognosis while under different types of medications. PATIENTS AND METHODS: This study is a retrospective observational cohort study conducted at Bahrain Defence Force (BDF) Royal Medical Services. Medical records of COVID-19 patients admitted to BDF hospital, treated, and followed up from April 2020 to October 2020 were retrieved. Data were analyzed using univariate and multivariate logistic regression with covariate adjustment, and the odds ratio (OR) and 95% confidence (95% CI) interval were reported. RESULTS: Among 353 patients admitted with COVID-19, 47.6% developed AKI. Overall, 51.8% of patients with AKI died compared to 2.2% of patients who did not develop AKI (p< 0.001 with OR 48.6 and 95% CI 17.2-136.9). Besides, deaths in patients classified with AKI staging were positively correlated and multivariate regression analysis revealed that moderate to severe hypoalbuminemia (<32 g/L) was independently correlated to death in AKI patients with an OR of 10.99 (CI 95% 4.1-29.3, p<0.001). In addition, 78.2% of the dead patients were on mechanical ventilation. Besides age as a predictor of AKI development, diabetes and hypertension were the major risk factors of AKI development (OR 2.04, p<0.01, and 0.05 for diabetes and hypertension, respectively). Also, two or more comorbidities substantially increased the risk of AKI development in COVID-19 patients. Furthermore, high levels upon hospital admission of D-Dimer, Troponin I, and ProBNP and low serum albumin were associated with AKI development. Lastly, patients taking ACEI/ARBs had less chance to develop AKI stage II/III with OR of 0.19-0.27 (p<0.05-0.01). CONCLUSIONS: The incidence of AKI in hospitalized COVID-19 patients and the mortality rate among AKI patients were high and correlated with AKI staging. Furthermore, laboratory testing for serum albumin, hypercoagulability and cardiac injury markers maybe indicative for AKI development. Therefore, clinicians should be mandated to perform such tests on admission and follow-up in hospitalized patients.
