RESUMO
This study focuses on applying phytoremediation as a low-effective and simple process to treat wastewater laden with 1,4 dioxane (DIOX). A floating macrophyte (Eichhornia crassipes) was cultivated under hydroponic conditions (relative humidity 50-67%, photoperiod cycle 18:6 h light/dark, and 28-33 °C) and subjected to different DIOX loads between 0.0 (control) and 11.5 mg/g fresh mass (FM). The aquatic plant achieved DIOX and chemical oxygen demand (COD) removal efficiencies of 76-96% and 67-94%, respectively, within 15 days. E. crassipes could tolerate elevated DIOX-associated stresses until a dose of 8.2 mg DIOX/g, which highly influenced the oxidative defense system. Malondialdehyde (MDA) content, hydrogen peroxide (H2O2), and total phenolic compounds (TPC) increased by 7.3, 8.4, and 4.5-times, respectively, in response to operating the phytoremediation unit at a DIOX load of 11.5 mg/g. The associated succulent value, proteins, chlorophyll-a, chlorophyll-b, and pigments dropped by 39.6%, 45.8%, 51.5%, 80.8%, and 55.5%, respectively. The suggested removal mechanism of DIOX by E. crassipes could be uptake followed by phytovolatilization, whereas direct photodegradation from sunlight contributed to about 19.36% of the total DIOX removal efficiencies. Recycling the exhausted E. crassipes for biochar production was a cost-efficient strategy, making the payback period of the phytoremediation project equals to 6.96 yr.
Eichhornia crassipes could be used in phytoremediation of 1,4 dioxane (DIOX)-laden water at DIOX load< 8.2 mg/g FM. E. crassipes removed 7797% DIOX via uptake and phytovolatilization. Recycling exhausted-plant to produce biochar was cost-efficient with 7 yr-payback period.

In March 2020, the SARS-CoV-2 virus outbreak was declared as a world pandemic by the World Health Organization (WHO). The only measures for controlling the outbreak are testing and isolation of infected cases. Molecular real-time polymerase chain reaction (PCR) assays are very sensitive but require highly equipped laboratories and well-trained personnel. In this study, a rapid point-of-need detection method was developed to detect the RNA-dependent RNA polymerase (RdRP), envelope protein (E), and nucleocapsid protein (N) genes of SARS-CoV-2 based on the reverse transcription recombinase polymerase amplification (RT-RPA) assay. RdRP, E, and N RT-RPA assays required approximately 15 min to amplify 2, 15, and 15 RNA molecules of molecular standard/reaction, respectively. RdRP and E RT-RPA assays detected SARS-CoV-1 and 2 genomic RNA, whereas the N RT-RPA assay identified only SARS-CoV-2 RNA. All established assays did not cross-react with nucleic acids of other respiratory pathogens. The RT-RPA assay's clinical sensitivity and specificity in comparison to real-time RT-PCR (n = 36) were 94 and 100% for RdRP; 65 and 77% for E; and 83 and 94% for the N RT-RPA assay. The assays were deployed to the field, where the RdRP RT-RPA assays confirmed to produce the most accurate results in three different laboratories in Africa (n = 89). The RPA assays were run in a mobile suitcase laboratory to facilitate the deployment at point of need. The assays can contribute to speed up the control measures as well as assist in the detection of COVID-19 cases in low-resource settings.

BACKGROUND: Timely antenatal care (ANC) has been proven to save lives and maximizes health and potential. The study aimed to assess ANC utilization rates in Damietta district, Egypt and to identify the components of ANC provided and factors affecting utilization rates. METHODS: A cross-sectional study was conducted in four Family Health Centers (FHC) in Damietta district. The study included any mother, who gave birth within the last 6 months, after giving written consent to participate. Women were interviewed about their experience with ANC during the last pregnancy using a pre-designed questionnaire. RESULTS: The study found that ~85% of the mothers have ever attended ANC during the last pregnancy, two-thirds were regular attendants. Urban residence, being not working, having high education and high family income were positively associated with utilization of ANC (P < 0.001). Only 30% of the mothers received ANC in FHCs, while the majority received ANC at private clinics. Rates of receiving ANC components were variable with significantly higher rates in private clinics than governmental FHCs (P < 0.001 for most components). Health education was the least ANC component to be received by mothers at governmental and private sites. CONCLUSION: More work is needed to improve the utilization of ANC in FHCs. Providers of ANC should be trained and supervised to provide full package of ANC especially health education message, being the most neglected component of ANC.

RESUMO
BACKGROUND: The aim of this study is investigate the antimicrobial effect of plant oils against bacterial strains isolated from neonatal asymptomatic bacteriuria (ABU) and to evaluate the antiseptic effect of the most potent one. METHODS: The antimicrobial effect of 17 plant oils were tested against 15- gram-negative bacterial strains recovered from cases of neonatal ABU (11 Escherichia. coli, 3 Klebsiella pneumonia, and 1 Pseudomonas aeruginosa) using the agar well diffusion method. The micro-dilution method was performed to investigate the minimum inhibitory concentrations (MIC) and the minimum bactericidal concentrations (MBC) in concentrations ranging from 1.95 µg/ml to 500 µg/ml. The evaluation of the antiseptic activity of the Eruca sativa (arugula) seed oil was investigated using time-kill assay in concentrations ranging from 50 µg/ml to 0.195 µg/ml. RESULTS: All tested oils showed variable antimicrobial activities against the tested strains. Arugula, wheat germ, cinnamon, parsley, dill, and onion oils were the most active oils. Among them, arugula oil was the most active oil with MIC50 and MIC90 were 3.9 µg/ml and 31.3 µg/ml respectively. MBC50 and MBC90 of arugula oil were 15.6 µg/ml and 125µg/ml respectively. The time-kill assay of arugula oil indicated that a concentration of 100 µg/ml completely killed nine of the tested strains after 10 min and reduced the CFU/ml of the rest of the strains by 3 log10 at the same time interval. CONCLUSION: Arugula seed oil could be a potentially used as an antiseptic especially for neonates.

Background and Objectives: With the increase in immunosuppressed patients and antimicrobial misuse, Bacillus species have risen as opportunistic pathogens in hospitalized patients. The present study aimed at comparing chromogenic media, automated identification cards versus MALDI-TOF as the gold standard method for identification of different Bacillus species and determining minimal inhibitory concentration (MIC) of different antibiotics by broth microdilution method (BMD) to suggest recommendations for Bacillus treatment. Materials and Methods: The study included 30 Bacillus species isolates recovered from normally sterile sites of the human body and were subjected to identification by MALDI-TOF, Vitek-2c, and HiCrome Bacillus Agar. BMD test was performed to determine the MIC of vancomycin, gentamicin, and ciprofloxacin. Results: Our study showed B. cereus was the most commonly isolated species (76.66%) followed by B. subtilis (23.33%). Regarding the different methods of identification, the highest agreement with MALDI-TOF was exhibited by HiCrome agar without polymyxin B (93.3%) followed by Vitek-2C and HiCrome agar with polymyxin with an agreement of 83.3%. Concerning the antibiogram, the tested isolates showed a susceptibility of 93.3%, 86.6%, and 83.3% towards vancomycin, gentamicin, and ciprofloxacin respectively. Conclusion: In conclusion, we spotlight that Bacillus species should no longer be considered contaminant bacteria in cultures, particularly in immunosuppressed patients. HiCrome Bacillus Agar without polymyxin B displayed the highest agreement with MALDI-TOF. Hence, it represents a good option for identification for routine laboratories where expensive instruments are unavailable. The high susceptibility towards the tested antibiotics can suggest the possibility of empirical use of vancomycin, gentamicin, and ciprofloxacin.
RESUMO
BACKGROUND: Several SARS-CoV-2 variants with increased transmissibility and/or potential immune escape have emerged and rapidly spread worldwide. Ongoing surveillance analyses are performed worldwide to designate new variants of concern (VOC) of coronavirus. MAIN TEXT: This report identifies the first Egyptian patient with a confirmed SARS-CoV-2 omicron variant. The patient showed positivity on reverse transcriptase-polymerase chain reaction and full genome sequencing was performed to confirm the variant. The mutations found in the variant were compared with the GISAID reference strain hCoV-19/Wuhan/WIV04/2019. Genome BLAST showed the highest similarity to omicron variants isolated in South Africa. Phylogenetic analysis revealed that the variant belongs to the 21K clade. CONCLUSIONS: The study indicates the importance of information-sharing among global public health partners. Moreover the importance of implementation of full genome sequencing to rapidly identify and track the new SARS-CoV-2 variants.
RESUMO
AIMS: Vitamin D plays an important role in the regulation of ovulatory dysfunction. We aimed to study the effect of vitamin D on letrozole-induced PCOS in female rats. MATERIAL & METHODS: 40 non-pregnant Wistar rats were divided into four groups: group I control (received 1 ml of 1% aqueous solution of (CMC)/d orally), group II letrozole-induced PCOS group (received letrozole 200 µg/d orally), group III vitamin D-treated group (received vitamin D 1000 IU/kg/d), group IV letrozole and vitamin D treated group (received letrozole and vitamin D as group II and group III for 90 days. BMI, ovarian weight, serum vitamin D, biochemical metabolic and oxidative stress markers were evaluated, ovarian tissues glutathione, malondialdehyde levels and caspase-3 activity were measured. Histopathological examination of the ovary and coronary artery were done. KEY FINDINGS: Letrozole-induced typical PCOS with significant decrease in vitamin D and coronary vasculopathy. Group II shows insignificant change in all parameters but there is significant increase in vitamin D and decrease in triglyceride and glutathione. In group VI all parameters were significantly improved but coronary vasculopathy was partly improved. Vitamin D was significantly negatively correlated with all parameters but significantly positively correlated with estradiol, insulin sensitivity, and HDL and insignificantly correlated with glutathione. Both Insulin resistance and testosterone were significantly positively correlated with all parameters but significantly negatively correlated with estradiol, insulin sensitivity, HDL and glutathione. SIGNIFICANCE: These results holding the promise of beneficial impact of vitamin D administration to PCOS and its associated cardiovascular disorders.

Trans Fatty Acid (TFA) intake is a risk factor for coronary heart diseases and cancer. Egypt, considered among the highest TFA consumers in the world, lacks proper dietary analysis of TFAs. This cross-sectional study aimed to analyze TFAs in traditional and frequently consumed food products. A market survey was conducted to identify products and brands that are mostly consumed in major governorates in Egypt. Laboratory analysis allowed for the profiling of TFAs, and saturated and unsaturated fatty acids. Products having more than 2 g of TFA/100 g of fat were considered to have an elevated TFA content. Commonly consumed food items (n = 208) in the Egyptian market were identified. On average, 34% of the products exceeded the TFA limit. Sambosk meat, a traditional meat item, had the highest TFA content of 5.2%, followed by foods fried with used oils. Oriental sweets had a TFA content three times higher than that of doughnuts. The fast-food group had the largest proportion of TFA-rich products, followed by the canned and frozen item groups and confectionaries. This study revealed that around one third of products in the Egyptian market have a high TFA content. This calls for urgent legislative action to regulate composition.

BACKGROUND: : microRNAs are playing important roles in the diagnosis and prognosis of pediatric acute lymphoblastic leukemia (ALL). METHODS: Expression levels of miR-100 and miR-210 were assessed in bone marrow aspirate of 85 pediatric ALL patients compared to 12 healthy control using quantitative real-time polymerase chain reaction. Data were correlated with relevant clinico-pathological features of the patients, response to treatment, disease-free survival (DFS), and overall survival (OS). RESULTS: miR-100 was significantly downregulated in ALL patients [median: 1.21, range: 0-434.3] compared to the control group [median: 8.41, range; 0-840.3, P = 0.035]. miR-210 was significantly upregulated in ALL patients [median: 6.34, range: 1.16-1088.7] compared to the control group [median: 2.57, range: 0.11-709.2, P = 0.025]. The sensitivity, specificity, and area under curve of miR-100 were (64.7%, 62.5%, and 0.642; respectively, P = 0.035) at a cut-off 2.6 and that of miR-210 were (60%, 58.3% and 0.650; respectively, P = 0.025) at a cut-off 3.5. miR-100 overexpression associated with shorter DFS and OS (P = 0.033 and 0.046; respectively). Patients with miR-100 lowexpression showed a significant incidence of late death ( P = 0.024). There was no significant association between miR-210 expression and DFS, OS, incidence of early or late death. CONCLUSION: : miR-100 and miR-210 could be used as potential diagnostic markers for pediatric ALL. miR-100 is a useful prognostic and predictive biomarker for childhood ALL.

Evidence suggests that opioids can modulate gonadal function, with consequent decreased release of sex hormones. We attempted to investigate the sexual function of males using tramadol hydrochloride (HCL) and its relationship to levels of free testosterone, luteinizing hormone, and follicle stimulating hormone, and to compare them with heroin use disorder patients and healthy controls. Our sample consisted of 60 opiate use disorder patients (assessed by Structured Clinical Interview for DSM-IV Axis I) (30 heroin and 30 tramadol) and 30 healthy controls. Sexual dysfunction was assessed using the International Index of Erectile Function. Free testosterone, follicle stimulating hormone, and luteinizing hormone levels were measured in morning blood samples using enzyme-linked immunosorbent assay (ELISA). Results showed that there was a decrease of luteinizing hormone and free testosterone levels in opiate use disorder patients compared with healthy controls, with heroin-dependent patients having significantly lower levels than those using tramadol. Opiates' effect on follicle stimulating hormone had mixed results. Opioid-dependent patients (both tramadol HCL and heroin using patients) developed sexual dysfunction more than healthy controls, which was generalized, with erectile dysfunction being the most affected domain. These findings are of ultimate importance, considering the fact that people use opioids to enhance their sexual performance in many countries.

Objective: To describe the epidemiology of carbapenem-resistant Enterobacteriaceae (CRE) healthcare-associated infections (HAI) in Egyptian hospitals reporting to the national HAI surveillance system. Methods: Design: Descriptive analysis of CRE HAIs and retrospective observational cohort study using national HAI surveillance data. Setting: Egyptian hospitals participating in the HAI surveillance system. The patient population included patients admitted to the intensive care unit (ICU) in participating hospitals. Enterobacteriaceae HAI cases were Klebsiella, Escherichia coli, and Enterobacter isolates from blood, urine, wound or respiratory specimen collected on or after day 3 of ICU admission. CRE HAI cases were those resistant to at least one carbapenem. For CRE HAI cases reported during 2011-2017, a hospital-level and patient-level analysis were conducted using only the first CRE isolate by pathogen and specimen type for each patient. For facility, microbiology, and clinical characteristics, frequencies and means were calculated among CRE HAI cases and compared with carbapenem-susceptible Enterobacteriaceae HAI cases through univariate and multivariate logistic regression using STATA 13. Results: There were 1598 Enterobacteriaceae HAI cases, of which 871 (54.1%) were carbapenem resistant. The multivariate regression analysis demonstrated that carbapenem resistance was associated with specimen type, pathogen, location prior to admission, and length of ICU stay. Between 2011 and 2017, there was an increase in the proportion of Enterobacteriaceae HAI cases due to CRE (p-value = 0.003) and the incidence of CRE HAIs (p-value = 0.09). Conclusions: This analysis demonstrated a high and increasing burden of CRE in Egyptian hospitals, highlighting the importance of enhancing infection prevention and control (IPC) programs and antimicrobial stewardship activities and guiding the implementation of targeted IPC measures to contain CRE in Egyptian ICU's .

The changes in plant growth, transpiration rate, photosynthetic activity, plant pigments, electrolyte leakage, H2O2 content, lipid peroxidation, catalase activity and endogenous content of abscisic acid (ABA) were followed in the leaves of two wheat varieties (sakha 93 and 94) during drought stress and subsequent rehydration. Drought stress caused several inhibitory changes in the growth of both wheat varieties, particularly in sakha 94. Exogenous ABA treatment improved the growth of sakha 93 plants as indicated by a higher relative water content, transpiration rate and lower electrolyte leakage and also enhanced the growth during the recovery period. Such improvement may be the result of the induction of enzymatic (catalase) and non-enzymatic (carotenoid) systems. ABA treatment did not ameliorate the negative effect of drought on the growth of sakha 94.

INTRODUCTION: Tuberculosis (TB) remains a huge worldwide burden, despite extensive vaccination coverage with the Bacillus Calmette-Guérin (BCG), the only vaccine available against this disease, indicating that BCG-driven immunity is inadequate to protect the human population against TB. This underscore the critical necessitate to develop an improved TB vaccine, based on a better understanding of host-pathogen interactions and immune responses during mycobacterial infection. AIM OF THE WORK: To examine whether the exogenous addition of IFN-ß could improve dendritic cell (DC) response to Mycobacterium bovis (M. bovis) and to evaluate the effect induced by the infection of human DCs with M. bovis (with and without IFN-ß) and Mycobacterium tuberculosis (Mtb) on DC viability as well as to compare the ability of BCG and Mtb to provide DCs with a Th1-polarizing capacity through the assessment of the immunoregulatory cytokines interleukin (IL)-12, IL-10 and interferon-gamma (IFN-γ). METHODS: Immature DCs (iDCs) were generated in vitro using peripheral blood monocytes separated by anti-CD14-conjugated microbeads in the presence of granulocyte-macrophage-colony-stimulating factor (GM-CSF) and IL-4, cultured cells were analyzed using flow cytometry, then we tested DC viability after inoculation with M. bovis (with and without IFN-ß pretreatment) and Mtb using light microscopic examination and trypan blue exclusion method. Additionally, supernatants from infected-DCs cultures were analyzed for IFN-γ, IL-12 and IL-10 by ELISA. RESULTS: The viability of BCG-infected DCs was significantly higher than that of Mtb-infected DCs (61.55% vs 52.10%). BCG-infected DC produced significantly more IL-12 (pâ¯=â¯0.02) and less IL-10 (pâ¯=â¯0.01) compared with Mtb-infected cells. IFN-ß-pretreated BCG-infected DCs produced significantly larger amounts of IL-12 than did BCG-infected DCs (pâ¯=â¯0.03) and Mtb-infected cells (pâ¯<â¯0.001). CONCLUSION: IFN-ß improves DC functions following BCG infection, thus assuming that IFN-ß could be used as a vaccine adjuvant.

Background. Methicillin-resistant Staphylococcus aureus (MRSA) has created significant epidemiological, infection-control, and therapeutic management challenges during the past three decades. Aim. To analyze the pattern of resistance of healthcare- and community-associated MRSA in Egypt and the trend of resistance of HA-MRSA over time (2005-2013). Methods. MRSA isolates were recovered from healthcare-associated (HA) and community-associated (CA) Staphylococcus aureus (S. aureus) infections. They were tested against 11 antimicrobial discs and the minimal inhibitory concentration (MIC) of vancomycin was determined. Inducible clindamycin resistance (iMLSB) was also screened using D-test. Findings. Of 631 S. aureus, MRSA was identified in 343 (76.6%) and 21 (11.5%) of HA and CA S. aureus isolates, respectively. The proportion of HA-MRSA increased significantly from 48.6% in 2005 to 86.8% in 2013 (p value < 0.001). Multidrug resistance (MDR) was observed in 85.8% of HA-MRSA and 48.6% of CA-MRSA. Vancomycin intermediate resistant S. aureus (VISA) was detected in 1.2% of HA-MRSA and none was detected in CA-MRSA. Among HA-MRSA strains, 5.3% showed iMLSB compared to 9.5% among CA-MRSA. Conclusion. The upsurge of the prevalence rates of HA-MRSA over time is alarming and urges for an effective infection control strategy and continuous monitoring of antimicrobial use.
RESUMO
BACKGROUND: Health care-associated infections (HAIs) are a major global public health concern. The lack of surveillance systems in developing countries leads to an underestimation of the global burden of HAI. We describe the process of developing a national HAI surveillance program and the magnitude of HAI rates in Egypt. METHODS: The detailed process of implementation of a national HAI surveillance program is described. A 3-phase surveillance approach was implemented in intensive care units (ICUs). This article focuses on results from the phase 2 surveillance. Standard surveillance definitions were used, clinical samples were processed by the hospital laboratories, and results were confirmed by a reference laboratory. RESULTS: Ninety-one ICUs in 28 hospitals contributed to 474,544 patient days and 2,688 HAIs. Of these, 30% were bloodstream infections, 29% were surgical site infections, 26% were pneumonia, and 15% were urinary tract infections. Ventilator-associated pneumonia had the highest incidence of device-associated infections (4.3/1,000 ventilator days). The most common pathogens reported were Klebsiella spp (28.7%) and Acinetobacter spp (13.7%). Of the Acinetobacter spp, 92.8% (157/169) were multidrug resistant, whereas 42.5% (151/355) of the Klebsiella spp and 54% (47/87) of Escherichia coli were extended-spectrum ß-lactamase producers. CONCLUSIONS: Implementation of a sustainable surveillance system in a resource-limited country was possible following a stepwise approach with continuous evaluation. Enhancing infection prevention and control programs should be an infection control priority in Egypt.

Corynebacterium urealyticum is a Gram positive, slow-growing, lipophilic, multi-drug resistant, urease positive micro-organism with diphtheroid morphology. It has been reported as an opportunistic nosocomial pathogen and as the cause of a variety of diseases including but not limited to cystitis, pyelonephritis, and bacteremia among others. This review serves to describe C. urealyticum with respect to its history, identification, laboratory investigation, relationship to disease and treatment in order to allow increased familiarity with this organism in clinical disease.
RESUMO
OBJECTIVE: To measure the impact of an antimicrobial stewardship (AMS) program on the use of antibiotics for surgical prophylaxis at acute care hospitals in Egypt. METHODS: This was a before-and-after intervention study conducted in 5 tertiary, acute-care surgical hospitals. The baseline, intervention, and follow-up periods were 3, 6, and 3 months, respectively. The impact of the intervention was measured by preintervention and postintervention surveys for surgical patients with clean and clean-contaminated wounds. Information was collected on demographic characteristics and antibiotic use. The intervention focused mainly on educating surgical staff on the optimal timing and duration of antibiotics used for surgical prophylaxis. Only 3 hospitals identified a surgeon to audit antibiotic surgical prescriptions. The primary outcome measures were the percentages of surgical patients receiving optimal timing and duration of surgical prophylaxis. RESULTS: Data were collected for 745 patients before the intervention and for 558 patients after the intervention. The optimal timing of the first dose improved significantly in 3 hospitals, increasing from 6.7% to 38.7% (P < .01), from 2.6% to 15.2% (P < .01), and from 0% to 11% (P < .01). All hospitals showed a significant rise in the optimal duration of surgical prophylaxis, with an overall increase of 3%-28% (P < .01). Days of therapy per 1000 patient-days were decreased significantly in hospitals A, B, C, and D, with no change in hospital E. CONCLUSIONS: An AMS program focusing on education supported by auditing and feedback can have a significant impact on optimizing antibiotic use in surgical prophylaxis practices.

Inappropriate antibiotic use leads to increased risk of antibiotic resistance and other adverse outcomes. The objectives of the study were to determine the prevalence and characteristics of antibiotic use in Egyptian hospitals to identify opportunities for quality improvement. A point prevalence survey was conducted in 18 hospitals in March 2011. A total of 3408 patients were included and 59% received at least one antibiotic, with the most significant use among persons <12 years and intensive care unit patients (p < 0.05). Third generation cephalosporin were the most commonly prescribed antibiotics (28.7% of prescriptions). Reasons for antibiotic use included treatment of community-(27%) and healthcare-associated infections (11%) and surgical (39%) and medical (23%) prophylaxis. Among surgical prophylaxis recipients, only 28% of evaluable cases received the first dose within two hours before incision and only 25% of cases received surgical prophylaxis for <24 h. The prevalence of antibiotic use in Egyptian hospitals was high with obvious targets for antimicrobial stewardship activities including provision of antibiotic prescription guidelines and optimization of surgical and medical prophylaxis practices.
