Abstract
BACKGROUND Measurement of the circulating levels of long-non-coding RNAs (lncRNAs) in lupus nephritis (LN) patients could dramatically explore more insights about the disease pathogenesis. Hence, we aimed to quantify the level of expression of CTC-471J1.2 and NeST in LN patients and to correlate it with the disease activity. METHOD This case-control study was conducted on a group of children with juvenile LN attending to Mansoura University Children's Hospital (MUCH). Demographics, clinical, and laboratory findings were collected besides the measurement of lncRNAs by quantitative real-time PCR. RESULTS The expression level of lncRNAs-CTC-471J1.2 was significantly down-regulated in children with active LN versus inactive cases or controls. In contrast, the NeST was significantly up-regulated in active LN cases. A significant correlation was found between CTC-471J1.2 expression and LN activity parameters. Additionally, both lncRNAs showed a reasonable sensitivity and specificity in differentiation of active LN. A regression analysis model revealed that CTC-471J1.2 and NeST were independent predictors of active nephritis. CONCLUSION The expression level of circulatory lncRNAs-CTC-471J1.2 and NeST can be used as sensitive and specific biomarkers for active LN. Furthermore, both could serve as predictors for nephritis activity.

Abstract
A significant public health issue worldwide is metabolic syndrome, a cluster of metabolic illnesses that comprises insulin resistance, obesity, dyslipidemia, hyperglycemia, and hypertension. The creation of natural treatments and preventions for metabolic syndrome is crucial. Chitosan, along with its nanoformulations, is an oligomer of chitin, the second-most prevalent polymer in nature, which is created via deacetylation. Due to its plentiful biological actions in recent years, chitosan and its nanoformulations have drawn much interest. Recently, the chitosan nanoparticle-based delivery of CRISPR-Cas9 has been applied in treating metabolic syndromes. The benefits of chitosan and its nanoformulations on insulin resistance, obesity, diabetes mellitus, dyslipidemia, hyperglycemia, and hypertension will be outlined in the present review, highlighting potential mechanisms for the avoidance and medication of the metabolic syndromes by chitosan and its nanoformulations.

Abstract
BACKGROUND Bisphenol-A (BPA) has a well-proven deleterious effect on the hypothalamicpituitary- gonadal axis. OBJECTIVES The current study investigated the therapeutic potentials of mesenchymal stem cells (MSCs) in a murine model of BPA-induced ovarian damage. METHODS Fifty adult female rats were divided into: Group 1; control group, Group IIa, IIb: rats were given oral gavage of BPA (25 and 50 mg/Kg body weight respectively) on a daily basis for 15 days, and Group IIIa, IIIb; rats were intravenously treated with of MSCs (106 cells) after receiving the last dose of BPA as in group II. Plasma and ovarian tissue levels of Malondialdehyde (MDA) and gonadal axis hormones were assessed. Apoptosis was evaluated by TUNNEL assay and by apoptosis markers (FAS, FASL, Caspase 3, SLTM). A histological examination of ovarian tissue was also conducted. RESULTS BPA resulted in a significant elevation in plasma levels of LH, FSH, and ovarian tissue levels of MDA and a significant decrease in estradiol and progesterone. All genetic and protein markers of apoptosis were elevated in BPA treated group with decreased oestrogen receptor expression in the ovarian tissue. Increased apoptotic cells were confirmed by TUNEL assay. A high dose of BPA was able to increase the number of atretic follicles in the ovarian tissue whereas the numbers of primordial, primary, secondary and Graafian follicles were decreased. All the laboratory and histological abnormalities were ameliorated by treatment with MSCs. CONCLUSION The antioxidant and anti-apoptotic effects of MSCs could possibly explain the ability of this therapeutic modality to ameliorate BPA-induced-ovarian damage.

Abstract
INTRODUCTION The Ministry of Health in Saudi Arabia provides comprehensive antenatal care for all pregnant women with all required investigations. However, it does not include urine culture for diagnosis of asymptomatic bacteriuria (ASB). This is the first study to evaluate the prevalence of ASB among pregnant females, identify the causative organisms and determine their antibiotic susceptibility patterns in the Maternity and Children's Hospital, Arar, Saudi Arabia. METHODOLOGY This cross-sectional study included 400 pregnant women attending an antenatal clinic. Two midstream urine samples were aseptically collected and screened using standard microbiological techniques including microscopic examination, dipstick testing, and urine culture. In order to interpret the urine culture results, ≥ 105 CFUs/mL was considered significant bacteriuria. Identification of the isolates and their antibiotic sensitivity testing was performed using the Vitek 2 system (BioMérieux, Marcy l'Etoile, France) with the available test kits. RESULTS The prevalence of ASB was 8.25% (35/400). Significant positive correlations (p ˂ 0.05) were detected between positive urine culture results and random blood sugar, leucocytes, nitrites, pus cells, urine red blood cells, epithelial cells, and mucus. Escherichia coli was the most common causative organism (45.7%), followed by Staphylococcus aureus (22.9%). Klebsiella pneumoniae represented 11.4% of the isolates. Most of the isolated Gram-positive organisms were sensitive to many of the tested antibiotics; most of the detected Gram-negative isolates were resistant. CONCLUSIONS ASB caused by antibiotic resistant organisms is alarming. Screening for ASB during pregnancy using urine culture and sensitivity testing is of vital importance to improve the maternal and neonatal outcome.

Abstract
Although self-service facilities (SSFs) have been used on a large scale worldwide, they can be easily contaminated by microorganisms from the hands of their sequential users. This research aimed to study the prevalence and antimicrobial susceptibility/resistance of bacteria contaminating SSFs in Sakaka, Aljouf, Saudi Arabia. We randomly swabbed the surfaces of 200 SSFs, then used the suitable culture media, standard microbiological methods, and the MicroScan WalkAway Microbiology System, including the identification/antimicrobial susceptibility testing-combo panels. A high SSFs' bacterial contamination load was detected (78.00%). Ninety percent of the samples collected in the afternoon, during the maximum workload of the SSFs, yielded bacterial growth (p < 0.001 *). Most of the contaminated SSFs were supermarket payment machines, self-pumping equipment at gas stations (p = 0.004 *), online banking service machines (p = 0.026 *), and barcode scanners in supermarkets. In the antiseptic-deficient areas, 55.1% of the contaminated SSFs were detected (p = 0.008 *). Fifty percent of the contaminated SSFs were not decontaminated. The most common bacterial contaminants were Escherichia coli (70 isolates), Klebsiella pneumoniae (66 isolates), Staphylococcus epidermidis (34 isolates), methicillin-resistant Staphylococcus aureus (18 isolates), and methicillin-sensitive Staphylococcus aureus (14 isolates), representing 31.53%, 29.73%, 15.32%, 8.11%, and 6.31% of the isolates, respectively. Variable degrees of reduced sensitivity to some antimicrobials were detected among the bacterial isolates. The SSFs represent potential risks for the exchange of antimicrobial-resistant bacteria between the out-hospital environment and the hospitals through the hands of the public. As technology and science advance, there is an urgent need to deploy creative and automated techniques for decontaminating SSFs and make use of recent advancements in materials science for producing antibacterial surfaces.

Abstract
Short-term health insurance policies-made available with longer durations during the Trump Administration-offer substantially fewer consumer protections than do Affordable Care Act ("ACA")-compliant policies. Federal regulations require short-term policies' sellers to disclose possible ACA noncompliance to prospective buyers. This controlled experiment finds, however, that the federally required disclosure does not substantially improve consumer understanding of these policies' coverage limitations. The experiment also finds that an enhanced disclosure greatly improves this understanding. Importantly, consumers' preferences for ACA-compliant policies also increased with their comprehension of the coverage differences. Thus, the study demonstrates not only that easily implemented changes in the federally required disclosure would improve consumer understanding of the coverage differences but also that the improved understanding matters to consumers. However, even the enhanced disclosure left many respondents mistaken about some key limitations of short-term policies, suggesting that policymakers should consider other strategies to protect buyers of short-term health insurance.

Abstract
Cytokine storm is one of the leading causes of death in patients with COVID-19. Metformin has been shown to inhibit the action of a wide range of proinflammatory cytokines such as IL-6, and TNF-α which may ultimately affect cytokine storm due to Covid-19. The present study analyzed the anti-inflammatory effect of oral and intraperitoneal (IP) metformin administration routes in a mouse model of lipopolysaccharide (LPS)-induced cytokine storm. A total of 60 female BALB/c mice were randomly assigned to one of six groups: i) Control; ii) LPS model; iii) oral saline + LPS; iv) oral metformin + LPS; v) IP saline + LPS; and vi) IP metformin + LPS. Metformin or saline were administered to the mice for 30 days, after which an IP injection of 0.5 mg/kg LPS induced a cytokine storm in the five treatment groups. Mice were sacrificed and serum cytokine levels were measured. Pretreatment of mice with either oral or IP metformin significantly reduced the increase in IL-1, IL-6 and TNF-α following LPS injection. Both metformin administration routes significantly reduced IL-1 and TNF-α levels, although IP metformin appeared to be significantly more effective at reducing IL-6 levels compared with oral metformin. Neither the oral or IP route of administration of metformin demonstrated a significant effect on IL-17 levels. Based on its ability to suppress the proinflammatory LPS-induced cytokine storm, metformin may have future potential benefits in ameliorating human diseases caused by elevated cytokine levels.

Abstract
Reboxetine (REB) and sertraline (SER) are antidepressants. The antifungal potential of these drugs against planktonic Candida has been recently reported with limited data about their effects on Candidal biofilms. Biofilms are self-derived extracellular matrixes produced by the microbial population that is attached to biotic surfaces, such as vaginal and oral mucosa, or abiotic surfaces, such as biomedical devices, resulting in persistent fungal infections. The commonly prescribed antifungals, azoles, are usually less effective when biofilms are formed, and most of the prescribed antifungals are only fungistatic. Therefore, the current study investigates the antifungal potentials of REB and SER, alone and in combination with fluconazole (FLC) and itraconazole (ITR) against Candidal biofilms. Using proper controls, Candida species (Candida albicans, C. albicans; Candida krusei, C. krusei; and Candida glabrata, C. glabrata) were used to form biofilms in 96-well microplates. Serial dilutions corresponding to concentrations ranging from 2 to 4096 µg/mL of the target drugs (REB, SER, FLC, ITR) were prepared and added to the plates. Impairment of the biofilm biomass and biofilm metabolic viability was detected using the crystal violet (CV) assay and 3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, respectively. In the checkerboard assay, the sessile fractional inhibitory concentration index (SFICI) was calculated to evaluate the effects of drug combinations. SER was more effective in reducing the biomass than REB for C. albicans and C. glabrata, but both were equal for C. krusei. For the reduction in metabolic activity in C. albicans and C. glabrata, SER had a slight advantage over REB. In C. krusei, REB was slightly more potent. Overall, FLC and ITR were almost equal and produced more significant reductions in metabolic activity when compared to SER and REB, except for C. glabrata, where SER was almost equal to FLC. Synergism was detected between REB + FLC and REB + ITR against biofilm cells of C. albicans. Synergism was detected between REB + ITR against biofilm cells of C. krusei. Synergism was detected between REB + FLC and REB + ITR against biofilm cells of C. albicans, C. krusei, and C. glabrata. The results of the present study support the potential of SER and REB as anti-Candidal biofilm agents that are beneficial as a new antifungal to combat Candidal resistance.

Abstract
INTRODUCTION Enterobacteriaceae that produce extended-spectrum beta-lactamase (ESBL) are quickly spreading, posing a threat to world healthcare. METHODOLOGY 138 gram-negative bacteria were collected from different samples (stool, urine, wound, blood, tracheal aspirate, catheter tip, vaginal swab, sputum, and tracheal aspirate) from hospitalized patients. Samples were subcultured and identified in accordance with their biochemical reactions and culture characteristics. Against all the isolated Enterobacteriaceae, an antimicrobial susceptibility test was performed. VITEK®2 system, phenotypic confirmation, and Double-Disk Synergy Test (DDST) had been utilized to identify the ESBLs. RESULTS Of the 138 samples studied, the prevalence of ESBL-producing infections among the clinical samples of the present study was 26.8 % (n = 37). E. coli was the commonest ESΒL producer at 51.4% (n = 19) followed by K. pneumoniae at 27% (n = 10). The potential risk factors for the ESBL development that produces bacteria were as follows, patients with the presence of indwelling devices, previous history of hospital admission, and usage of antibiotics. ESBL is statistically (p ≤ 0.05) higher among the patients with indwelling devices, ICU admission, who had a previous hospital admission in the last 6 months as well as who was given antibiotics (quinolones and/or cephalosporins) in the last 6 months. One hundred thirty-two (95.7%) of ESBL isolates were resistant to amoxicillin, while the lowest resistance was for fosfomycin (15.2%). CONCLUSIONS ESBL-producing Enterobacteriaceae are highly prevalent in Turaif General Hospital setting with some potential risk factors. A strict policy to be made available on the usage of antimicrobials in hospitals and clinics should be established.

Abstract
Ethanol-producing dysbiotic gut microbiota could accelerate the progress of non-alcoholic fatty liver disease (NAFLD). Metformin demonstrated some benefits in NAFLD. In the present study, we tested the ability of metformin to modify ethanol-producing gut bacterial strains and, consequently, retard the progress of NAFLD. This 12-week study included forty mice divided into four groups (n = 10); normal diet, Western diet, Western diet with intraperitoneal metformin, and Western diet with oral metformin. Oral metformin has a slight advantage over intraperitoneal metformin in ameliorating the Western diet-induced changes in liver function tests and serum levels of different cytokines (IL-1β, IL-6, IL-17, and TNF-α). Changes in liver histology, fibrosis, lipid content, Ki67, and TNF-α were all corrected as well. Faecal ethanol contents were increased by the Western diet but did not improve after treatment with metformin although the numbers of ethanol-producing Klebsiella pneumoniae (K. pneumoniae) and Escherichia coli (E. coli) were decreased by oral metformin. Metformin did not affect bacterial ethanol production. It does not seem that modification of ethanol-producing K. pneumoniae and E. coli bacterial strains by metformin could have a significant impact on the therapeutic potentials of metformin in this experimental model of NAFLD.

Abstract
Recruiting and retaining sufficient participants is one of the biggest challenges researchers face while conducting clinical trials (CTs). This is due to the fact of misconceptions and insufficient knowledge concerning CTs among the public. The present cross-sectional study was conducted from April 2021 to May 2022. We evaluated knowledge and attitude among 480 participants using a pretested Arabic questionnaire. The correlation between knowledge and attitude score was tested through Spearman's correlation test, and the logistic regression test evaluated the associated factors for knowledge and attitude. Of the studied participants, 63.5% were male and belonged to the age group less than 30 years (39.6%). Nearly two-thirds (64.6%) of them had never heard of CT. More than half of the participants had poor knowledge (57.1%) and attitude (73.5%) towards CTs. Participants' knowledge scores were significantly associated with education level (p = 0.031) and previous participation in health-related research (p = 0.007). Attitude scores were significantly related to marital status (p = 0.035) and the presence of chronic diseases (p = 0.008). Furthermore, we found a significant positive correlation between knowledge and attitude scores (p < 0.001, Spearman's rho = 0.329). The present study revealed that most of the study population had poor knowledge and moderate attitudes towards CT. Targeted health education programs at different public places are recommended to improve the public's knowledge of the importance of CT participation. In addition, exploratory and mixed-methods surveys in other regions of KSA is required to recognize the region-specific health education needs.

Abstract
INTRODUCTION Acute transverse myelitis is an uncommon inflammatory, intramedullary, disorder of the spinal cord. Spastic paraplegia, impaired sphincter functions, and sensory loss, with sensory level, are the clinical manifestations of this devastating disorder. The utilization of magnetic resonant imaging (MRI) contributes to the surge in the diagnosis of more ATM cases. Although the causes of ATM are numerous, both Mycoplasma pneumoniae and Schistosoma mansoni are uncommon causes and their co-existence in the same patient has not been reported before in Saudi Arabia. CASE We report a 25-year-old ATM male patient presented with a history of sudden onset severe low back pain. Within four hours from the onset of the back pain, he became completely paraplegic with impaired functions of the bowel and urinary bladder sphincter. Furthermore, he lost all modalities of sensory functions in the lower limbs. His examination revealed spastic complete paraplegia with sensory level at T6. Clinical neurological examination revealed normal upper limbs and brain functions. The MRI of the cervico-dorsal spine showed extensive longitudinal hyperintense lesion extending from the upper cervical segments to the lower dorsal segments (extensive longitudinal transverse myelitis). A post-infectious immune-mediated predisposition was highly suspected due to the very high titers of anti-Mycoplasma pneumoniae IgM and IgG that were detected. The immunosuppressant therapy did not improve his paraplegia. A spinal cord biopsy revealed the presence of several Schistosoma mansoni ova surrounded by chronic inflammatory reactions and reactive gliosis. CONCLUSIONS Both Mycoplasma pneumoniae and Schistosoma mansoni should be investigated in cases with extensive longitudinal ATM.

Abstract
(1) Backgrounds and Objectives: The global battle to contain the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) is still ongoing. This cross-sectional study aimed to detect the seroprevalence of anti-SARS-CoV-2 IgM/IgG among previously symptomatic/asymptomatic and vaccinated/unvaccinated inhabitants of Sakaka City, Aljouf, Saudi Arabia. (2) Methods: Blood samples of 400 participants were tested for the presence of anti-SARS-CoV-2 IgM/IgG using colloidal gold immuno-chromatography lateral flow immunoassay cards. (3) Results: The prevalence of anti-SARS-CoV-2 IgM and IgG positivity was 45.8% and 42.3%, respectively. Statistically significant correlations (p < 0.05) were found between the previous RT-PCR testing for SARS-CoV-2-RNA and positivity for IgM and/or IgG. The highest seroprevalence of IgM and IgG were detected among smokers, participants aged ≥40 years, and patients with chronic diseases. Although most of the participants (58.5%) did not previously experience COVID-19 like symptoms, the anti-SARS-CoV-2 IgM and IgG seropositivity amongst them was 49.1% and 25.6%, respectively, with higher seroprevalence among males than females. At the time of the study, the SARS-CoV-2 vaccination rate at our locality in Saudi Arabia was 43.8% with statistically significant correlation (p < 0.001) between being vaccinated and anti-SARS-CoV-2 IgM and/or IgG positivity, with more positivity after receiving the second vaccine dose. (4) Conclusions: Public assessment reflects the real scale of the disease exposure among the community and helps in identifying the asymptomatic carriers that constitute a major problem for controlling the SARS-CoV-2. To limit the spread of the virus, rigorous implementation of large-scale SARS-CoV-2 vaccination and anti-SARS-CoV-2 serological testing strategies should be empowered.

Abstract
INTRODUCTION Severe acute respiratory syndrome - Coronavirus-2 (SARS-CoV-2) is mainly transmitted via respiratory secretions through coughing, sneezing, or contact with contaminated surfaces. This virus can be present in feces and many body fluids. The study aimed to screen the hospital environment as a potential source for SARS-CoV-2 transmission and identify the hospital zones with the highest contamination levels. METHODOLOGY Swabs were collected from different sites in the hospital before and after routine cleaning/disinfection, transported in vials containing 1-3 mL of viral transport medium, and stored at -80 ℃ as soon as possible until the time of testing. The real-time reverse-transcription PCR (rRT-PCR) system targeting RNA-dependent RNA polymerase and E genes was used to detect the SARS-CoV-2 RNA. RESULTS Moderate environmental contamination by SARS-CoV-2 RNA was detected by rRT-PCR before routine cleaning/disinfection (52% of the swabs were positive). The hospital surfaces with the highest contamination levels were elevators' buttons, sinks and faucets' handles at the waiting rooms, patient's room and bathroom, call buttons and telephones in the patient's room, toilet bowl surface, the doorknob and light switches at the X-ray room, and the computer keyboard at the staffroom. All the swabs collected after routine cleaning/disinfection were negative for SARS-CoV-2 RNA by rRT-PCR. CONCLUSIONS The hospital environment is a high-risk area that can be contaminated by SARS-CoV-2 through contact, respiratory, and maybe fecal shedding of the virus. To limit this fatal virus transmission, strict adherence to proper hand hygiene with frequent optimal decontamination of hospital environmental surfaces is essential.

Abstract
INTRODUCTION Saudi Arabia can be considered a hot spot for Methicillin-resistant Staphylococcus aureus (MRSA) infections with significant regional variations. As far as we know, this is the first study to evaluate the prevalence of MRSA in clinical samples obtained from Turaif general hospital (TGH), Northern Area-Saudi Arabia, and screening the resistance profile to the most regularly used antimicrobials as an indicator for evaluation of the implemented infection control measures. METHODOLOGY Totally, 410 Samples were collected from patients in TGH with clinically suspected nosocomial infections. MRSA isolates were identified by the classical bacteriological, biochemical, and cefoxitin-based methods as recommended by the Clinical Laboratory Standard Institute. Confirmation of isolates and testing of their antimicrobial susceptibilities were performed by the automated Vitek 2 compact system. RESULTS Totally, 130 nosocomial isolates were detected. Staphylococcus aureus (29.23%) was the most frequently isolated Gram-positive pathogen. MRSA represented 39.47% of Staphylococcus aureus and 11.54% of all isolates. MRSA-causing surgical site infections were the most predominant type of MRSA nosocomial infections representing (25.00%). Recent antibiotic therapy, prolonged hospital stays, and indwelling devices were significant risk factors for the development of MRSA infections. Although all MRSA isolates were sensitive to vancomycin, teicoplanin, linezolid, Fosfomycin, and tigecycline, many isolates were resistant to other tested antimicrobials. CONCLUSIONS Hospital administrators should strengthen the ideal use of antibiotics according to the local hospital policy to control the selective drug pressure on Staphylococcus aureus strains with minimizing exposure to the risk factors by implementing the proper infection control policies.

Abstract
AIMS The aim was to evaluate the role of HLA-DP/DQ single-nucleotide polymorphisms (SNPs) in Helicobacter pylori infection in Kafrelsheikh governorate, Egypt. METHODS AND RESULTS The study enrolled 120 persons; 48 naïve H. pylori-infected patients, 42 relapsers and 30 H. pylori-free controls. Gastroscopy, H. pylori stool antigen, anti-CagA and anti-VacA antibodies were determined. Genotyping of HLA-DPA1rs3077 (A/G) SNP and HLA-DQ-rs3920(A/G) SNP was done using real-time PCR. The antibody profile against H. pylori showed that 85.7% of patients with recurrent infection have IgG against CagA (p = 0.001*). There was a significant association between the occurrence of H. pylori infection and both HLA-DPA1rs3077AA and HLA-DQ-rs3920AG genotypes. Concerning H. pylori relapse, the HLA-DQ-rs3920AG genotype was detected in 78.6% of patients with recurrent infection (p = 0.002*). Patients carrying this genotype tend to be relapsers 9.8 times more than patients carrying other genotypes. CONCLUSIONS HLA-DPA1rs3077AA and/or HLA-DQ-rs3920AG genotypes could be risk factors for the occurrence of H. pylori infection. HLA-DQ-rs3920AG genotype is markedly linked to recurrent H. pylori infection. SIGNIFICANCE AND IMPACT OF THE STUDY Host factors as HLA gene polymorphism could be a predisposing factor for susceptibility, recurrence or chronicity of H. pylori and should be studied in different ethnic groups.

Abstract
(1) Backgrounds and Objectives: Since its discovery, information about the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) has spread rapidly. However, many issues remain unresolved. Coronaviruses are primarily transmitted through respiratory secretions. The possibility of transmission via donated blood transfusion deserves studying. This is the first study in Saudi Arabia to look at pre-vaccination donated blood anti-SARS-CoV-2 antibody content as a marker for virus transmission via viral RNA positive blood and/or the potential therapeutic value of convalescent plasma. (2) Methods: A total of 300 blood samples were sequentially collected from unvaccinated donors who donated blood to the blood bank of Prince Mutaib Bin Abdulaziz Hospital in Sakaka, Al-Jouf, Saudi Arabia. Specific ELISA was used to detect anti-SARS-CoV-2 IgG and IgM antibodies. SARS-CoV-2 was detected using specific real-time reverse-transcription PCR (rRT-PCR). (3) Results: The prevalence of anti-SARS-CoV-2 IgG was low (9%), whereas the prevalence of anti-SARS-CoV-2 IgM was high (65%). Relevant demographics, anthropometrics, and lifestyle factors revealed significant associations (p < 0.05) between IgM-positivity only vs. age (age group 21−30 years), postgraduate education, no history of international travel, IgG-negativity, and absence of experience with COVID-19-like symptoms. Furthermore, there are significant associations (p < 0.05) between IgG-positivity only vs. age (age group 21−30 years), postgraduate education, and being a non-healthcare worker. All donors in the anti-SARS-CoV-2 IgG-positive group (n = 27) had previously experienced symptoms similar to COVID-19 (p < 0.001) and most of them (n = 24) showed anti-SARS-CoV-2 IgM-positive test (p = 0.006). However, all the samples tested negative for SARS-CoV-2 RNA using rRT-PCR. (4) Conclusion: Our findings add to the growing body of evidence that donated blood is safe, with the added benefit of convalescent plasma rich in potentially neutralizing IgG and IgM against SARS-CoV-2.

Abstract
Purpose Obesity is associated with fat accumulation in ectopic sites such as the pancreas, the so-called pancreatic steatosis (PS). Bariatric surgery has been shown to be associated with reducing pancreatic fat. This study investigated the effect of laparoscopic sleeve gastrectomy (LSG) on pancreatic volume and its fat content and glucose homeostasis. Methods The study enrolled 54 patients subjected to LSG. Metabolic variables and pancreatic exocrine function were assessed immediately before surgery and 12 months after. MRI of the abdomen was performed to measure pancreatic fat content and its total volume and visceral adipose tissue (VAT). Results Surgery resulted in a significant reduction in body weight and BMI. HbA1c, fasting insulin, C-peptide levels, HOMA-IR, and Hs-CRP levels decreased significantly. Surgery resulted in significant improvement in lipid profile except for HDL-cholesterol and liver function tests. Total VAT volume decreased significantly. Total pancreas volume decreased by a mean of 9.0 cm3 (95% CI: 6.6–11.3). The median change of pancreatic fat was −26.1% (range: −55.6 to 58.3%). Pancreatic lipase decreased significantly (P < 0.001). There was a positive correlation between the percentage of total weight loss and decrease in pancreatic fat volume (r = 0.295, P = 0.030). Conclusion Weight loss after LSG is associated with a reduction of total VAT volume, total pancreatic volume, and pancreatic fat content. These changes are associated with improved glucose homeostasis, reduced systemic inflammation, and decreased pancreatic lipase secretion.

Abstract
PURPOSE A number of disinfectants and sanitisers are used in dentistry, and there are numerous commercial solutions available. Nonetheless, because each cleaning solution has its own set of indications and limits, there is no one-size-fits-all approach for processing all types of dental equipment. Functional water, such as electrolysed hypochlorite microbubbled water, efficiently eliminates and sterilises biofilms. The objective of the study was to evaluate whether ozonated water could be used to sterilise and disinfect dental-unit water pipelines (DUWP) that had been contaminated with micro-organisms, including Gram-positive and Gram-negative bacilli and cocci. MATERIALS AND METHODS Three different groups were formed: group A - ozonated water (Cantoosh); group B - 1% povidine iodine; and group C: conventional distilled water. Group A was the test group, group B the control group, and group C was the positive control group. The water sterilising system was replaced with the appropriate sterilising agent as per the allocated group classification, with 2 min of purging, so that the complete DUWP was filled with the water sterilising system. Samples were collected and analysed, along with a 2-min purge after 24 h, 7 days and 21 days, at the 3 outlet (OL) points: the 3-way syringe at the dental tray(OL1), the cup filler (OL2), and the 3-way syringe of the assistant zone (OL3). Repeated measures ANOVA was used to test for statistical significance between colony-forming units of control and experimental groups (p < 0.05). RESULTS The cup filler yielded higher counts than did the 3-way syringe at the dental tray (OL1) (6.40 and 8.05 on the log scale, respectively). A statistically significant difference in the CFUs was also observed between samples taken after 24 h vs 21 days between groups A, B and C. CONCLUSION The findings showed that exposing DUWP tube systems to ozonated water for an extended length of time drastically lowered the number of microorganisms adhering to their surfaces.

Abstract
Clostridium difficile present in feces of food animals may
contaminate their meats and act as a potential source of C.
difficile infection (CDI) to humans. C. difficile
resistance to antibiotics, its production of toxins and spores play major roles
in the pathogenesis of CDI. This is the first study to evaluate C.
difficile prevalence in retail raw animal meats, its antibiotics
susceptibilities and toxigenic activities in Al-Jouf, Saudi Arabia. Totally, 240
meat samples were tested. C. difficile was identified by
standard microbiological and biochemical methods. Vitek-2 compact system
confirmed C. difficile isolates were 15/240 (6.3%).
Toxins A/B were not detected by Xpect C. difficile toxin A/B
tests. Although all isolates were susceptible to vancomycin and metronidazole,
variable degrees of reduced susceptibilities to moxifloxacin, clindamycin or
tetracycline antibiotics were detected by Epsilon tests. C.
difficile strains with reduced susceptibility to antibiotics should
be investigated. Variability between the worldwide reported C.
difficile contamination levels could be due to absence of a gold
standard procedure for its isolation. Establishment of a unified testing
algorithm for C. difficile detection in food products is
definitely essential to evaluate the inter-regional variation in its prevalence
on national and international levels. Proper use of antimicrobials during animal
husbandry is crucial to control the selective drug pressure on C.
difficile strains associated with food animals. Investigating the
protective or pathogenic potential of non-toxigenic C.
difficile strains and the possibility of gene transfer from certain
toxigenic/ antibiotics-resistant to non-toxigenic/antibiotics-sensitive strains,
respectively, should be worthy of attention.

Abstract
Systemic lupus erythematosus (SLE) is a chronic autoimmune illness with a growing prevalence in many populations. Few studies have examined genetic predisposition to SLE, so we aimed to examine the clinical impact of the genetic polymorphisms MECP2 rs2734647and TIRAP rs8177374 on the outcomes and therapeutic precision of SLE with and without nephritis. This study included 110 SLE patients-divided into 63 with lupus nephritis (LN), and 47 without nephritis-and 100 controls. Laboratory measurements including CRP, ESR, ACR, CBC, anti-ds-DNA, vitamin A, C3, and C4 were carried out, along with genotyping of MECP2 rs2734647and TIRAP rs8177374 by real-time PCR and sequencing. Treg %, vitamin A, C3, and C4 were lower, whereas Th17 % was higher, in patients vs. controls (p < 0.001). The T allele of MECP2 rs2734647 was higher in LN than in non-nephritis and control subjects. Moreover, the T allele of TIRAP rs8177374 was higher in LN than in non-nephritis and control subjects. The MECP2 and TIRAP genes could play a role in predisposition to SLE, and can also predict disease progress to nephritis, helping to personalize medicine.

Abstract
OBJECTIVES Living donor liver transplant is the gold standard therapy for patients with terminal hepatic disorders for whom no alternative therapy is available. The primary aim was to assess different intraoperative factors that may predict early death after adult-to-adult living donor liver transplant. The secondary aim was to assess the effect of small-for-size syndrome on mortality. MATERIALS AND METHODS This retrospective multicenter cohort study was performed on records from 145 adults with cirrhosis who had received a right lobe living donor liver transplant. Patients were divided according to the occurrence of short-term mortality (death within the first month after transplant). The primary intraoperative parameters included graft weight, surgical duration, mean blood pressure, serum lactate and sodium bicarbonate, transfusions, durations of cold and warm ischemia and anhepatic phase, input and output during surgery, and portal venous pressures. RESULTS There were statistically significant variations between both cohorts for number of units of packed red blood cells, durations of cold and warm ischemia and anhepatic phase, preclamp and postreperfusion portal venous pressures, average urine output, mean serum lactate, mean blood pressure, and surgical duration (P ⟨ .001). Also, there were significant differences in the number of platelets, units of fresh frozen plasma, and mean sodium bicarbonate (P = .025, .003, and .035, respectively). Of the 25 patients who died within the early postoperative period, 20 had developed small-for-size syndrome (P ⟨ .001). CONCLUSIONS A variety of intraoperative risk factors may affect early posttransplant mortality, which suggests the high complexity of living donor liver transplants and the need for well-trained experienced teams to perform these surgeries.

Abstract
The world is currently facing the COVID-19 pandemic, caused by the novel Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). Due to a lack of specific treatment and prophylaxis, protective health measures that can reduce infection severity and COVID-19 mortality are urgently required. Clinical and epidemiological studies have shown that vitamin D deficiency can be linked to an increased risk of viral infection, including COVID-19. Therefore, in this review, we looked at various possible roles of vitamin D in reducing the risk of COVID-19 infection and severity. We describe in this article that individuals at high risk of vitamin D deficiency should consider taking vitamin D supplements to keep optimal concentrations. Moreover, we discuss different possible mechanisms by which vitamin D can efficiently reduce the risk of infections through modulation of innate and adaptive immunity against various types of infections. It is advisable to perform further studies addressing the observed influence of vitamin D levels to reduce the risk of COVID-19 infection and mortality.

Abstract
INTRODUCTION Efforts have been made to contain COVID-19. Human behavior, affected by knowledge and perceptions, may influence the course of disease. METHODOLOGY A structured questionnaire was used to collect data from 422 participants. It consisted of 28 questions in four sections; seven questions about sociodemographic characteristics of participants, 12 questions to estimate level of knowledge about COVID-19, six questions to evaluate attitudes toward disease, and three questions to assess practices to prevent disease transmission. RESULTS Their overall understanding of COVID-19 was satisfactory. 69% of the participants had satisfactory levels of knowledge, and the main sources of information were social media platforms (79.70%) and television (70.90%). There was a significant difference in knowledge as a function of gender (p = 0.50), occupation (p = 0.012), and smoking (p = 0.041). The participants held optimistic attitudes and adopted appropriate protective measures. Most participants agreed that COVID-19 can cause death (64.7%), poses greater risks to elderly (93.4%) and those with chronic diseases (96.7%), it is mandatory to quarantine infected individuals (98.1%), preventive health measures are important (97.6%), and health authorities will succeed in controlling the pandemic (67.5%). There was a statistically significant association between satisfactory levels of knowledge and the practice of wearing masks and the adoption of protective measures (avoiding crowded places, frequent hand washing). CONCLUSIONS Residents of Al-Jouf region in Saudi Arabia have satisfactory levels of knowledge, optimistic attitudes, and good practice during the rapid rise period of the pandemic. Awareness campaigns will improve any misbeliefs and risky behaviors.

Abstract
OBJECTIVE The effect of garlic powder (GP) and phenyl acetic (PA) acid throughout the fattening period of broiler chickens on performance, blood parameters, immune, and antioxidant parameters as well as carcass traits was evaluated. METHODS A total of 210 day-old Cobb broiler chicks were randomly distributed into seven dietary treatments having five replications with six chicks per replicate. The first group (control) fed a basal diet without supplements, whereas the 2nd, 3rd, and 4th group were fed basal diet plus 0.25, 0.50, and 0.75 g GP/kg diet, respectively and the group 5th, 6th, and 7th were fed on the basal diet plus 0.25, 0.50, and 0.75 g PA/kg diet. RESULTS Broiler body weight and gain at 21 and 42 days were increased (p<0.05) with diets supplemented with GP and PA. Red blood cells and hemoglobin were improved in chickens fed diets enriched with GP. Broiler chickens received diets containing either GP or PA recorded the higher values (p<0.05) of total protein, globulin, high-density lipoprotein, immunoglobulin M (IgM), and IgG, superoxide dismutase and total antioxidant capacity; while, blood total cholesterol, low-density lipoprotein, aspartate-aminotransferase, and malondialdehyde were lowered (p<0.05) compared to control-diet. Liver and immune-related organs weight were improved (p<0.05) in broilers fed diet supplemented with GP and PA. CONCLUSION Feeding of GP or PA in diet had positive effects on performance traits and immunological, antioxidant and physiological status of broilers. Thus, the use of tested feed additives as an eco-friendly alternative to antibiotics produced a positive effect on animal health.

Abstract
The present investigation aimed to explore the impact of dietary graded levels of 2 types of probiotic bacteria (Bacillus toyonensis [BT] and Bifidobacterium bifidum [BB]) on growth, carcass traits, meat quality, and bacteriology of growing Japanese quail reared under the cage system. One thousand three hundred sixty Japanese quail day-old chicks were randomly divided into 10 groups (8 replicates each). Birds were fed a basal diet (control, T1) and the basal diet plus 0.05, 0.075, 0.10, and 0.125% BT (T2, T3, T4, and T5, respectively), 0.10% BB (T6), and the same previous doses of BT plus 0.05% BB (T7, T8, T9, and T10, respectively). Results showed a significant (P < 0.001) increase in final BW and weight gain because of probiotic supplementation (except T2 for weight gain). Both feed intake and feed conversion ratio did not differ during the overall experimental period (1–42 D of age) except feed intake that was reduced in T2 and increased in T5 and T9 groups. All carcass traits studied were significantly (P < 0.01) affected by probiotics, and the combination between BT and BB in group T8 increased all studied parameters as compared with the other treatment groups. The quail meat color of redness a∗ and L∗ values, thiobarbituric content, cooking loss, proteolysis, and total coliform were decreased (P < 0.001) by probiotic treatment. In general, supplementing BT, BB, or their combination to the basal diet delayed the proliferation of pathogenic bacteria in the diet and intestine. Using BT and BB as feed supplements enhanced growth performance and meat quality of quails as well as diminished pathogenic bacteria proliferation in their diet and intestine. As per our results, we can recommend the application of T5 and T8 to T10 levels for the best performance, carcass traits, and meat quality of growing quails.

Abstract
The present study investigated the impact of dietary oil sources (soybean, corn, peanut, flaxseed, olive, and sunflower oils as sources of omega 3, 6, and 9 fatty acids) on productive and reproductive traits, egg quality, hematological and biochemical blood parameters of laying Japanese quail. A total of 360 eight-week mature Japanese quail were randomly divided into 6 groups fed for 8 wk on a basal diet included with 1.5% of different oil sources. Results showed that the highest egg weights and the best feed conversion ratio (P < 0.01) were recorded for quail fed diets supplemented with 1.5% soybean and peanut oil. The highest hatchability percentages (P < 0.05) were recorded for quail fed diets supplemented with corn oil as compared to the other oils. Furthermore, diets enriched with corn, olive, or sunflower oils had higher values of blood lymphocytes (%) compared to the other treated groups. Blood total cholesterol significantly decreased in quail fed on corn, peanut, flaxseed, or olive oil sources as compared to soybean or sunflower oil groups. Immunologically, the highest levels (P < 0.001) of immunoglobulins (G and M) were recorded for quail fed on corn or olive oil sources compared to other oil sources. Quail consuming olive oil–included diets showed a significant increase in superoxide dismutase and glutathione S-transferase activities and a significant decrease on malondialdehyde level compared with those consumed the other oil sources. It could be concluded that varying the oil source can affect productive, reproductive, and health aspects of Japanese quail. Soybean oil showed good results regarding production aspects; however, olive oil was the best regarding health aspects.

Abstract
This study aimed to investigate the effect of using breeder parents (434-days-old) and broiler chickens (37 D of age) from Ross 308 on meat quality parameters and carcass characteristics; sex and muscle type were also estimated. Carcass assessment involved hot carcass weight, carcass yield, and cuts (breast, legs, wings, back, and shoulder). A total of 120 birds were divided into 2 groups (60 birds from each stock), each stock contain equal number of sexes (30 males and 30 females), and further divided into 6 replicates, so that there were 5 birds in each replicate. The birds were fed ad libitum. A sample of 30 birds (male, n = 15 and female, n = 15) from each group was slaughtered for assessing carcass and physical characteristics. Sensory analysis was carried out on each group after boiling or roasting the bird. Live weight, carcass weight and yield, breast weight, legs, wings, and back weights and yield were higher (P < 0.001) for breeder parents when compared to broilers, with the exception of breast percentage. Moreover, better carcass characteristics were observed in males than in females. Parent stock had better water-holding capacity and myofibrillar fragmentation whereas broilers had more tender meat than breeders. Moreover, cooking loss and other sensory characters were not significant between the two groups; however, females had more tender pectoral muscles and more myofibrillar fragmentation than males. We concluded that parent breeders had better carcass characteristics than broiler chickens. The broiler chickens of Ross 308 and female birds had better meat quality than parent breeders.

Abstract
The effect of a low-ME diet with a multienzyme (Kemzyme Plus, Kemin, Des Moines, IA) blend on performance, meat quality, and carcass traits was evaluated in Hubbard broiler chicks. A total of 120 Hubbard broiler chicks were allocated to the following 4 experimental groups and every group was separated into 6 replicates, with 5 birds per replicate: control (3,180 kcal/kg of ME), control + 0.50 g/kg diet of enzyme (Cont-Enz), low-ME diet (3,080 kcal/kg), and low-ME + 0.50 g/kg diet of enzyme (low-ME-Enz). The trail lasted for 16 D (32 to 48 D of age). No significant differences in growth parameters or carcass traits were observed among treatments. However, liver weight increased with the low-ME-Enz diet (P = 0.038). The low-ME diet recorded the highest weight for the bursa (P = 0.043) and thymus (P = 0.019). Dietary treatments had significant impacts on the length of duodenum, ileum, and cecum, as well as the weight of duodenum. The length of duodenum, ileum, and cecum increased with enzyme supplementation. The myofibril fragmentation index was lower with the Cont-Enz, low-ME, and low-ME-Enz diets than with the control diet (P = 0.043). The shear force increased with the low-ME-Enz diet (P = 0.022) than the control diet. Dietary treatments influenced breast meat yellowness (P = 0.019), whereas the low-ME diet had the lowest yellowness at the slaughtering age. The dietary treatments affected the breast meat pH (P = 0.001), with the control diet having the highest pH value after 24 hours. Thus, there was no effect of low-ME or enzyme supplementation to the control or low-ME diet on growth performance or carcass yield. However, feeding a low-ME diet or Cont-Enz preparation influenced organ and small intestine weights and meat characteristics.

Abstract
The effect of storage period on hatching and post-hatching performance of two quail breeds (brown Japanese quail (BJQ) and French white quail (FWQ)) was investigated using 940 eggs from each breed. Eggs were divided into four equal groups (235 eggs each), in each group. A total number of 210 eggs were used for incubation (with three replicates, 70 eggs each) and additional 25 eggs served as samples for egg quality parameters, each group was kept for special storage period. The first group was incubated on the same day of collection (zero day storage). Whereas the second, third, and fourth groups were stored for 4, 7, and 10 d, respectively. Increasing the storage period more than 4 d significantly decreased the relative albumen weight, yolk index, total hatchability, and fertile eggs but significantly increased the relative yolk/albumen ratio, absolute and relative egg weight loss. Moreover, FWQ eggs exhibited higher (P < 0.05) hatchability compared to BJQ eggs after 10 d of storage and yielded heavier chicks (P < 0.05) after all storage periods. The economic analysis indicated that the storage costs for FWQ eggs were significantly greater than those of BJQ at a 0 d of storage (2.42 vs. 4.81 US cent (¢); P < 0.05). Furthermore, the total costs for BJQ eggs were significantly lower than the total costs for FWQ eggs (3.0 vs. 7.0 ¢; P < 0.05). With respect to profitability, the total return represented by selling the chicks was calculated at 5.43 ¢ for BJQ and 9.01 ¢ for FWQ. The net return estimated for FWQ was significantly greater than that of BJQ (3.0 vs. 2.0 ¢; P < 0.05). However, the hatchability loss for FWQ was significantly greater than that of BJQ over different storage periods.

Abstract
We report a case of hospital-acquired pneumonia that to our knowledge is the first description in Egypt of the emergence of vancomycin (VA)-resistant Staphylococcus aureus due to the concomitant use of β-lactams. The combination of β-lactam antibiotics and VA in the treatment of methicillin-resistant S. aureus must be avoided to refrain from inducing VA resistance; further, if there is coinfection with Gram-negative bacilli, β-lactams must be avoided. If β-lactam antibiotic–induced VA-resistant methicillin-resistant S. aureus is isolated, then β-lactams must be avoided until the organism's sensitivity to VA is restored if VA is the only therapeutic option available.
