ABSTRACT
Blood transfusion is a critical life-saving medical intervention, but it carries the risk of transfusion-transmitted infections (TTIs) that can lead to serious consequences. TTIs include viral, bacterial, parasitic, and prion infections, transmitted through asymptomatic donor blood, contamination of stored blood products, or transfusion-related immunosuppression. Recognized global agents posing challenges to blood safety include human immunodeficiency virus (HIV), hepatitis C virus (HCV), hepatitis B virus (HBV), Syphilis, etc. Emerging pathogens like SARS-CoV-2, hepatitis E, and others present additional risks. The residual risk of TTIs, representing the likelihood of infected donations passing screening tests, varies globally. High-income countries generally show lower prevalence rates than low-income countries. In Egypt, the estimated prevalence rates for HIV, HBV, HCV, and syphilis markers among the donors are 0.23 %, 0.76 %, 2.33 %, and 0.24 %, respectively. In Egypt, specific residual risk estimates are scarce, but prevalence rates for key infections highlight existing challenges. The World Health Organization promotes a global blood safety strategy, advocating for national blood systems, voluntary non-remunerated donors, and quality-assured testing. Despite these measures, the establishment of a haemovigilance system which is critical for monitoring and preventing adverse events, including TTIs, is reported as lacking in Egypt. This highlights the importance of comprehensive surveillance and safety measures in the blood donation process to ensure universal access to safe blood. Primary health care can play a pivotal role in preventing TTIs.

Objective: Owing to the rising incidence of multidrug-resistant organisms (MDRO) and the high mortality rates associated with such bacterial infections post-hematopoietic stem cell transplantation (HSCT), we investigated the MDRO colonization rate prior to transplantation using an active surveillance approach and determined its impact on subsequent infection during the pre-engraftment period. Methods: A single-center observational study was conducted, and surveillance cultures from multiple body sites, including the rectum, nasal cavity, and groin, were performed at admission to determine MDRO colonization. Serological tests were used to detect certain viruses and toxoplasmosis before HSCT. Results: In the pre-transplant setting, 59 MDRO were recovered from the 40 HSCT recipients. Of the 59 isolates recovered from one or more body sites, 29 were positive for methicillin-resistant Staphylococcus aureus (MRSA), 7 for carbapenem-resistant Enterobacterales (CRE), and 23 were positive for extended-spectrum ß-lactamase (ESBLs). Serological assessment before HSCT revealed active or reactivation of latent infection with cytomegalovirus (7.5%), Epstein-Barr virus (EBV; 5%), and Toxoplasma gondii (2.5%) among HSCT patients. In terms of factors associated with pre-engraftment infections, the type of transplant (p=0.04) was statistically significant, whereas other factors, such as age, sex, and underlying conditions, were not. In post-transplant settings, bloodstream infections (BSIs) were documented in 2 allogeneic HSCT patients (5%), and the isolated microorganisms were ESBL-producing E. coli and non-MDR Acinetobacter baumannii. Conclusion: Active screening cultures are a helpful tool for identifying patients colonized by MDRO or relevant viruses before HSCT, and for predicting those at risk of developing subsequent pre-engraftment infections. Additionally, active screening may aid in predicting those who are likely to develop subsequent pre-engraftment infections Our findings highlight the importance of pre-transplant screening for high-priority multidrug-resistant pathogens and the application of infection control interventions after HSCT.
ABSTRACT
BACKGROUND: Multidrug-resistant (MDR) P. aeruginosa is a rising public health concern, challenging the treatment of such a ubiquitous pathogen with monotherapeutic anti-pseudomonal agents. Worryingly, its genome plasticity contributes to the emergence of P. aeruginosa expressing different resistant phenotypes and is now responsible for notable epidemics within hospital settings. Considering this, we aimed to evaluate the synergistic combination of fortimicin with other traditional anti-pseudomonal agents and to analyze the resistome of pan-drug resistant (PDR) isolate. METHODS: Standard methods were used for analyzing the antimicrobial susceptibility tests. The checkerboard technique was used for the in vitro assessment of fortimicin antibiotic combinations against 51 MDR P. aeruginosa and whole genome sequencing was used to determine the resistome of PDR isolate. RESULTS: Out of 51 MDR P. aeruginosa, the highest synergistic effect was recorded for a combination of fortimicin with ß-lactam group as meropenem, ceftazidime, and aztreonam at 71%, 59% and 43%, respectively. Of note, 56.8%, 39.2%, and 37.2% of the tested MDR isolates that had synergistic effects were also resistant to meropenem, ceftazidime, and aztreonam, respectively. The highest additive effects were recorded for combining fortimicin with amikacin (69%) and cefepime (44%) against MDR P. aeruginosa. Resistome analysis of the PDR isolate reflected its association with the antibiotic resistance phenotype. It ensured the presence of a wide variety of antibiotic-resistant genes (ß-lactamases, aminoglycosides modifying enzymes, and efflux pump), rendering the isolate resistant to all clinically relevant anti-pseudomonal agents. CONCLUSION: Fortimicin in combination with classical anti-pseudomonal agents had shown promising synergistic activity against MDR P. aeruginosa. Resistome profiling of PDR P. aeruginosa enhanced the rapid identification of antibiotic resistance genes that are likely linked to the appearance of this resistant phenotype and may pave the way to tackle antimicrobial resistance issues shortly.

PURPOSE: Respiratory muscle function is compromised in children recovering from chest wall burns, which potentially leads to more impact on exercise capacity and quality of life. This study investigates the effects of an inspiratory muscle training intervention accompanied with a pulmonary rehabilitation program on respiratory muscle strength, lung function, functional capacity, and quality of life in chest burned children. METHODS: Forty children with burns, aged from 10 to 18 years old and total body surface area of 30% to 50%, were randomly allocated to the inspiratory muscle training group (IMT- G: n = 20) or control group (CG: n = 20). They received IMT plus pulmonary rehabilitation or pulmonary rehabilitation with sham IMT, respectively for eight weeks. The outcomes were the respiratory muscle strength measured by maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP); lung functions (FEV1, FVC and FEV1/FVC ratio); functional capacity as well as Pediatric Quality of Life to measure physical and psychosocial functioning. outcome measures were assessed at before and after intervention (after eight weeks). RESULTS: Based on the pre-intervention assessments, we found no significant difference between both groups (p > 0.05). Significant post-intervention differences were reported between both groups in MIP (P = .003), MEP (P = .017), FVC (P = .001), FEV1 (P = .007), FEV1/FVC ratio (P = .028), functional capacity (P = .003), physical domain of QoL (P = .006) and psychological domain of QoL (P = .002) in favor of the IMT group. CONCLUSIONS: Eight weeks of inspiratory muscle training combined with pulmonary rehabilitation program improved children with chest burns' respiratory muscles strength, lung functions, functional capacity, and quality of life. Inspiratory muscle training may be employed in burn rehabilitation programs. It is a safe and effective therapy in chest burned children.

BACKGROUND: Variation in host immune responses to SARS-CoV-2 is regulated by multiple genes involved in innate viral response and cytokine storm emergence like IL-10 and TNFa gene polymorphisms. We hypothesize that IL-10; -592 C > A and - 1082 A > G and TNFa-308 G > A are associated with the risk of SARS-COV2 infections and clinical outcome. METHODS: Genotyping, laboratory and radiological investigations were done to 110 COVID-19 patients and 110 healthy subjects, in Ismailia, Egypt. RESULTS: A significant association between the - 592 A allele, A containing genotypes under all models (p < 0.0001), and TNFa A allele with risk to infection was observed but not with the G allele of the - 1082. The - 592 /-1082 CG and the - 592 /-1082/ -308 CGG haplotypes showed higher odds in COVID-19 patients. Severe lung affection was negatively associated with - 592, while positive association was observed with - 1082. Higher D-dimer levels were strongly associated with the - 1082 GG genotype. Survival outcomes were strongly associated with the GA genotype of TNFa. -308 as well as AGG and AAA haplotypes. CONCLUSION: IL-10 and TNFa polymorphisms should be considered for clinical and epidemiological evaluation of COVID-19 patients.

PURPOSE: The main aim of the trial was to assess the combined impact of graded Thera-Band strengthening exercises and scapular stabilization exercises on shoulder pain, physical function, and quality of life (QoL) in post-mastectomy adhesive capsulitis (AC). METHODS: Seventy females with unilateral post-mastectomy AC partook in the trial. Participants were subdivided equally into two groups at random. Both groups obtained the traditional physical therapy program; in addition, the intervention group received graded Thera-Band exercises for shoulder muscles and scapular stabilization exercises 5 days a week for 8 weeks. Range of motion (ROM) and muscle power of shoulder were assessed by digital goniometer and handheld dynamometer, respectively. Disability of the Arm, Shoulder, and Hand questionnaire (DASH) was utilized for assessment of shoulder function and visual analogue scale (VAS) for pain measurement while short-form (SF-36) for QoL assessment. All evaluation data was recorded prior to the trial and at the eighth week of interventions for both groups. RESULTS: All participants achieved improvements in shoulder ROM, muscle power, pain, and all aspects of QoL; however, higher statistical improvements were reported in all measurements with respect to strengthening exercises group (p < 0.001). CONCLUSION: The addition of graded Thera-Band strengthening exercises and scapular stabilization exercises in post-mastectomy AC rehabilitation program has significant benefits in shoulder function and patients' QoL. TRIAL REGISTRATION: This study is retrospectively registered at ClinicalTrials.gov NCT05311839.

Purpose: The cow's milk-related-symptom-score (CoMiSS) tool was developed as an awareness tool for the assessment of cow's milk-related symptoms in infants or children. Fecal calprotectin (FC) is a noninvasive biomarker of gut inflammation that can be measured in serum and stool. This study aimed to investigate the relationship between FC levels and CoMiSS scores in infants with cow's milk protein allergy. Methods: Infants (aged 6-12 months) who were allergic to cow's milk protein were enrolled prospectively. Following completion of the CoMiSS scoring, the infants were divided into group 1 (positive CoMiSS scores ≥12) and group 2 (negative CoMiSS scores <12). FC was measured using immunoassay. Results: Of the 120 infants enrolled in this study, 60 (50.0%) had positive CoMiSS scores (group 1), while 60 (50.0%) had negative scores (group 2). The mean FC level was higher in the infants in group 1 than those in group 2 (2,934.57 µg/g vs. 955.13 µg/g; p<0.001). In addition, there was a positive correlation between FC and CoMiSS scores (R=0.168, p<0.0001). A FC level of 1,700 µg/g provided a sensitivity of 98.3%, specificity of 93.3%, and accuracy of 95.8% for the diagnosis of cow's milk protein allergy (CMPA). Conclusion: FC measurement may have a role in the assessing infants with CMPA.
ABSTRACT
Serological assays for SARS-CoV-2 are being utilized at an exponential rate for surveillance programs. This enterprise was designed to develop and validate a qualitative immunochromatographic test, via the Lateral Flow Assay (LFA), for detection of immunoglobulins M and G (IgM and IgG) against both nucleocapsid (N) and the receptor-binding domain (RBD) of the spike protein of SARS-CoV-2. Both targeted proteins were cloned and expressed in baculovirus expression system utilizing insect cells Sf9. The recombinant RBD and N proteins were purified and conjugated with gold nanoparticles (AuNPs) to set up the coating antigens pad. Both anti-human IgG and IgM were dispensed on nitrocellulose membrane to capture human antibodies in serum samples. A home-made dispensing system was developed to draw identical test and control lines. The validity of the developed LFA was verified by testing serum samples from 103 convalescent COVID-19 patients who were PCR positive for SARS-CoV-2 along with 28 control serum samples. The developed strips showed distinctive bands for IgM and IgG of both proteins (RBD and N) in positive samples. The sensitivity of RBD-based LFA was 70.9% and 39.8% for IgG and IgM, respectively, with a specificity of 100% for both. The N-based LFA exhibited a sensitivity of 73.8% and 35.9% for IgG and IgM, respectively, while its specificity was 75% and 100% for IgG and IgM, respectively. Our developed LFA could afford a tool for surveillance programs in low-resource countries. Moreover, it might be functional for rapid and inexpensive monitoring of the anti-SARS-CoV-2 antibodies in the sera of vaccinated individuals.

BACKGROUND: Carbapenemase-producing Gram-negative (CPGN) bacteria impose life-threatening infections with limited treatment options. Rigor and rapid detection of CPGN-associated infections is usually associated with proper treatment and better disease prognosis. Accordingly, this study aimed at evaluating the phenotypic methods versus genotypic methods used for the detection of such pathogens and determining their sensitivity/specificity values. METHODS: A total of 71 CPGN bacilli (30 Enterobacterales and 41 non-glucose-fermenting bacilli) were tested for the carbapenemase production by the major phenotypic approaches including, the modified Hodge test (MHT), modified carbapenem inactivation method (mCIM), combined disk test by EDTA (CDT) and blue-carba test (BCT). The obtained results were statistically analyzed and correlated to the obtained resistant genotypes that were determined by using polymerase chain reactions (PCR) for the detection of the major carbapenemase-encoding genes covering the three classes (Class A, B, and D) of carbapenemases. RESULTS: In comparison to PCR, the overall sensitivity/specificity values for detection of carbapenemase-producing organism were 65.62%/100% for MHT, 68.65%/100% for mCIM, 55.22%/100% for CDT and 89.55%/75% for BCT. The sensitivity/specificity values for carbapenemase-producing Enterobacterales were, 74%100% for MHT, 51.72%/ 100% for mCIM, 62.07%/100% for CDT and 82.75%/100% for BCT. The sensitivity/specificity values for carbapenemase-producing non-glucose fermenting bacilli were, 62.16%/100% for MHT, 81.57%/100% for mCIM, 50/100% for CDT and 94.74%/66.66% for BCT. Considering these findings, BCT possess a relatively high performance for the efficient and rapid detection of carbapenemase producing isolates. Statistical analysis showed significant association (p < 0.05) between blaNDM and/or blaVIM genotypes with MHT/CDT; blaKPC/blaGIM genotypes with CDT and blaGIM genotype with BCT. CONCLUSION: The current study provides an update on the performance of the phenotypic tests which are varied depending on the tested bacterial genera and the type of the carbapenemase. The overall sensitivity/specificity values for detection of CPO were 65.62%/100% for MHT, 68.65%/100% for mCIM, 55.22%/100% for CDT and 89.55%/75% for BCT. Based on its respective diagnostic efficiency and rapid turnaround time, BCT is more likely to be recommended in a resource-limited settings particularly, when molecular tests are not available.

Hospital-acquired pneumonia (HAP) is a substantial public health issue that is associated with high mortality rates and is complicated by an arsenal of microbial etiologies, expressing multidrug-resistant phenotypes, rendering relatively limited therapeutic options. BioFire FilmArray Pneumonia Panel plus (BFPP) is a simple multiplexed PCR system that integrates sample preparation, nucleic acid extraction, amplification, and analysis of microbial etiology, with a turnaround time of about one hour. In comparison to standard culture methods, BFPP is simpler, easier to perform, and can simultaneously detect the most common pathogens involved in lower respiratory tract infections (34 targets). Accordingly, we evaluated the diagnostic performance of the multiplexed BFPP for the rapid detection of 27 clinically relevant respiratory pathogens and 7 genetic markers among 50 HAP cases admitted to the intensive care unit (ICU), who submitted mini-bronchoalveolar (mBAL) specimens. In comparison to standard culture methods, BFPP showed an overall sensitivity of 100% [95% CI; 90-100] and overall specificity of 90% [95% CI; 87.4-92.5] among all the tested bacterial targets. BFPP identified 11 viral targets (22%) among the tested specimens. The BFPP semi-quantitative analysis showed a concordance rate of 47.4% among positive culture specimens. For the investigation of the antibiotic resistance genes, BFPP showed a positive percent agreement (PPA), a negative percent agreement (NPA), and an overall percent agreement (OPA), reaching 97% [95% CI; 90-100], 95% [95% CI; 91.5-97], and 95% [95% CI; 93-97], respectively, with standard antibiotic sensitivity testing. In conclusion, BFPP has the potential to enhance the rapid microbiological diagnosis of HAP cases, and could aid in tailoring appropriate antibiotic therapies.
ABSTRACT
PURPOSE: This study compared the motor and sensory recovery and the operative time of autologous fibrin glue application with conventional microsuturing technique in repairing peripheral nerves at the forearm and wrist levels METHODS: Eighty-five patients with injuries of the median, ulnar, or both nerves at the wrist and forearm levels underwent nerve repair between September 2014 and June 2018. Patients were randomly assigned at the time of diagnosis to a microsuture group (42 patients), in which standard epineurial microsurgical suturing was performed, or a fibrin glue group (43 patients), in which nerve repair was performed using autologous fibrin glue. The primary outcome measure was motor and sensory recovery. Operative time was the secondary outcome measure. Other outcome measures that were added post hoc, after trial initiation, included time to motor and sensory recovery; grip strength; pinch strength; Michigan hand outcome score; amplitude, latency, and duration of the compound motor unit action potential; and complications. All patients were followed up a minimum of 1 year. RESULTS: At the final follow-up, both groups had regained similar motor and sensory function. The mean operative time was shorter in the fibrin glue group. Both groups had similar amplitude, latency, and duration of the compound motor unit action potential. Michigan Hand Outcome scores and mean percent recovery of grip strength and pinch strength were also similar. Six of 43 patients in the fibrin glue group compared with 8 of 42 patients in the microsuture group developed postoperative complications. CONCLUSIONS: The use of fibrin glue to repair peripheral nerves is as effective as microsuturing in regaining motor and sensory functions and is associated with shorter operative time. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

BACKGROUND: hypospadias is one of the most widespread male congenital anomalies, occurring in 1:250 to 1:300 live births. Several repair techniques have been developing to improve the outcomes. PURPOSE: a randomized prospective controlled study was adopted to evaluate effectiveness of autologous platelet gel in healing promotion and improving the outcomes of hypospadias repair. METHODS: thirty children who aged between 6 months and 12 years were recruited and subdivided into two groups; group A had tubularized incised plate (TIP) repair with autologous platelet gel application and group B had TIP repair without autologous platelet gel. RESULTS: there was no significant difference in duration of operation between both groups. All patients in groups A and B had slit-like meatus shape in the distal glans. While all those of group A had one urine stream, yet only 11 of group B had one. There were complications that happened exclusively in group B such as spray stream (27%) and fistula (20%). Whereas other complications occurred insignificantly more in group B than in A including meatal stenosis (53 versus 27%), glans dehiscence, (20 versus 7%), bleeding (33 versus 13%), infection (33 versus 27%), edema (27% versus13), respectively. The incidence of skin necrosis was equal in both groups. CONCLUSION: autologous platelet gel usage in TIP hypospadias repair can be a reliable technique to promote wound healing, and to limit of postoperative surgical complications.

The aim of the study was to assess acute kidney injury (AKI) and its contributing risk factors among neonates to reduce morbidity and mortality. The study included 310 neonates who were admitted to the neonatal intensive care unit (NICU). Serum creatinine (SCr) was elevated at admission, after 48 h, and before discharge or death. AKI was defined by either an acute rise in SCr of at least 0.3 mg/dL within 48 h or an increasing or persistently high level of SCr >1.5 mg/dL after 48-72 h of life. The patients who developed AKI were studied regarding the most common risk factors and outcomes. The prevalence of AKI in these neonates was 11.9%. Nephrotoxic drugs were the highest risk factor among patients with AKI, but this was not statistically significant different from patients without AKI. Perinatal asphyxia (59.5%), respiratory distress syndrome (48.6%), shock (43.2%), prematurity (40.5%), and sepsis (37.8%) were the main risk factors of AKI following the nephrotoxic drugs (64.9%). The mortality rate for cases with AKI was 62.1%, with a statistically significant difference from non-AKI neonates. The death rate was higher among neonates born before 36 weeks' gestation. There was no statistical difference between oliguric and non-oliguric neonates with AKI regarding the outcome. The overall incidence of AKI in sick neonates admitted to the NICU was 11.9%. Nephrotoxic drugs, perinatal asphyxia, shock, and prematurity were the main risk factors for developing AKI.

Severe burns lead to decreased pulmonary function and impaired aerobic capacity for long periods postinjury. Low-level laser therapy is a modality used to improve aerobic capacity, enhance exercise performance, and increase the time until fatigue when used before aerobic exercises. This work aims to determine the impacts of pre-exercise low-level laser therapy on aerobic capacity in burn cases. Sixty adults burned cases of both sex, aged from 25 to 40 years, with second-degree healed thermal burns, and the total burned body surface area ranged from 20 to 40% participated in this study after complete wound healing. They were randomly categorized into two groups of equal numbers. The study group received low-level laser therapy before aerobic exercises, three sessions per week for 12 weeks, while the control group performed aerobic exercises three times weekly for 12 weeks. All cases received the routine physical treatment program. Aerobic capacity was assessed for both groups by measuring maximum oxygen consumption and time to exhaustion at baseline and 12 weeks following interventions. There was a statistically significant rise in the mean values of maximum oxygen usage and time to fatigue after 12 weeks of treatment in both groups. However, after comparison, the improvements in the study group were statistically significant than those in the control group with P < .01 and P < .05, respectively. Low-level laser therapy has a beneficial therapeutic impact on promoting aerobic capacity, improving maximum oxygen consumption, and increasing treadmill time in burned cases when preceding aerobic exercises.

Background: Sepsis development in patients with trauma is associated with bad prognosis. This study investigated the effect of immunomodulatory interventions in major trauma patients at high risk for sepsis. Methods: In a randomized, double-blinded, controlled design, severe trauma patients were stratified by leukocyte anti-sedimentation rate (LAR) test into high risk (HR) and low risk (LR) for sepsis. The HR patients were randomly allocated into intravenous vitamin C plus vitamin B1 (HR-CB), intramuscular vitamin D plus oral Lactobacillus probiotics (HR-DP), or control (HR-C) groups. The clinical trial was registered at clinicaltrials.gov (https://clinicaltrials.gov/show/NCT04216459). Outcomes: The primary outcome was Acute Physiologic Assessment and Chronic Health Evaluation score II (APACHE II) score. Secondary outcomes included sepsis incidence, changes in Sequential Organ Failure Assessment (SOFA) score, and serum monocyte chemoattractant protein-1 (MCP-1) on day 6 from baseline, 28-day mortality, intensive care unit (ICU), and hospital discharge. Results: The HR-DP, HR-CB, and LR groups showed a significantly lower incidence of sepsis development (20%, 20%, and 16%, respectively, versus 60% in the HR-C group, p-value = 0.004). The three groups also showed a significant improvement in APACHE II and SOFA scores. Besides, MCP-1 levels were significantly decreased in HR-DP and HR-CB groups compared to the HR-C group (p-value ≤ 0.05). Significantly decreased mortality (10% and 16% versus 60% in the HR-C group) and increased ICU discharge (95% and 84% versus 45% in the HR-C group) were observed in HR-CB and LR groups (p-value = 0.001). Conclusion: Both combinations of interventions improved APACHE II scores and reduced sepsis incidence in trauma patients. The LAR combined with injury severity score were good sepsis predictors.
ABSTRACT
The current rise of multidrug-resistant (MDR) Gram-negative Enterobacteriaceae including the extended-spectrum ß-lactamase (ESBL)-producing organisms and carbapenem-resistant Enterobacteriaceae (CRE) has been increasingly reported worldwide, posing new challenges to health care facilities. Accordingly, we evaluated the impact of multimodal infection control interventions at one of the major tertiary healthcare settings in Egypt for the aim of combating infections by the respective pathogens. During the 6-month pre-intervention period, the incidence rate of CRE and ESBL-producing clinical cultures were 1.3 and 0.8/1000 patient days, respectively. During the post-intervention period, the incidence of CRE and ESBL producers continued to decrease, reaching 0.5 and 0.28/1000 patient days, respectively. The susceptibility rate to carbapenems among ESBL producers ranged from 91.4% (ertapenem) to 98.3% (imipenem), amikacin (93%), gentamicin (56.9%), and tobramycin (46.6%). CRE showed the highest resistance pattern toward all of the tested ß-lactams and aminoglycosides, ranging from 87.3% to 94.5%. Both CRE and ESBL producers showed a high susceptibility rate (greater than 85.5%) to colistin and tigecycline. In conclusion, our findings revealed the effectiveness of implementing multidisciplinary approaches in controlling and treating infections elicited by CRE and ESBL producers.
ABSTRACT
Till today, the globe is still struggling with the newly emerging infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and known as coronavirus disease 2019 (COVID-19). It has resulted in multiple fatalities from SARSs all around the world. A year after the global pandemic, the World Health Organization (WHO) has reported more than 79 million confirmed cases of COVID-19 and over 1.7 million deaths, making it one of the worst and most difficult pandemics encompassed in the modern history. The ongoing triad of escalating infections, mortality, and economic loss has urgently called for recognizing SARS-CoV-2 cell entry mechanisms as a crucial step in the initial stages of infection and to which possible interventional strategies should be targeted. To mediate host cell infections, Coronaviruses utilize the immunogenic studded spikes glycoproteins on its surface as a key factor for attachment, fusion, and entrance to host cells. Herein, we shed the light on a potential strategy involving disruption of SARS-CoV-2 S protein interaction with host cell receptors through design of neutralizing antibodies targeting receptor binding domain in S1 subunit, small peptide inhibitors, peptide fusion inhibitors against S2, host cell angiotensin converting enzymes 2 (ACE2), and protease inhibitors, aiming to pave the way for controlling viral cell entrance. In this review, we also highlight the recent research advances in the antiviral drugs that target the highly exposed spike protein, aiming to stem the COVID-19 pandemic.

Human factors account for most reported errors in the serious hazards of blood transfusion report, thus staff training on safe blood transfusion is strongly recommended. This study aimed to assess knowledge of blood transfusion safety among pediatricians and determine the impact of an educational initiative. A quasi-experimental study was conducted on 190 pediatricians. A questionnaire was designed and validated through a pilot study after which all participants were invited to fill it pre- and posteducational intervention. The educational material has been prepared based on the WHO blood transfusion safety guidelines; prepared by the researcher and reviewed by experts in the field. Near miss was identified by 47% of the participants and around 78.3%, 63.2%, and 60% of them correctly identified the indication of red blood cells, fresh frozen plasma, and platelet transfusion. These percentages were significantly improved post education. Only 55% knew that it's not allowed to co-administer drugs or IV fluids with the transfused blood and that rose to almost 80% after intervention. Consent information and correct patient identification were well known among most of them. Only 18.4% knew the pre transfusion screening protocol, which was increased to 85.8 % posteducation. Almost 65.3% correctly responded to the transfusion reaction quiz with no significant change after intervention. Age and work experience were significant independent risk factors for poor knowledge of transfusion safety. Transfusion safety knowledge needs further enhancement with more tailored training programs focusing on the topics that did not show a significant change after our educational training.

INTRODUCTION: Breast cancer stands out as the second most common cancer in the world with incidence 35.1% of all malignancies among females in Egypt. Fluid build-up after breast surgery is still the most annoying complication which leads to worse outcome. We aimed to evaluate whether autologous fibrin glue might lessen the formation of seroma following modified radical mastectomy. METHODS: This was a randomized controlled trial designed to configure the effect of autologous fibrin glue given in the study group using the drain in comparison to a control group who received the drain only; seroma volume was calculated every 24 h. For all of the cases. The drains were removed when the daily drainage was less than 30 ml for 3 consecutive days. RESULTS: We recruited 30 patients to each of the two groups. Age, pathology, breast cancer stage, number of lymph nodes and tumour size did not differ significantly between groups. A comparison of the median days to drain removal showed 8 days reduction in median days to drain removal compared in the intervention group (7 days) than the control (15 days). The patients in the fibrin glue group had a significantly lower cumulative drain output volume (mean ± SD of 505,6 ± 209,3 ml) than those in the control group (1674.1 ± 1 373,8 ml). CONCLUSIONS: Autologous fibrin glue significantly decrease seroma formation post-modified radical mastectomy.
