Using face masks appropriately is important for preventing the community spread of respiratory infections. A cross-sectional study was conducted to evaluate the knowledge level and experience of using face masks between healthcare teams to protect them and limit the spread of COVID-19 infection. A structured questionnaire was distributed to 228 healthcare members in July–December 2021. It was divided into two sections and consisted of 29 questions for a total possible score of 0 to 29. The first section was related to perceptions and knowledge about face masks (13 items); the second was related to the experience of using face masks (16 items). The average score of this questionnaire was 23.21/29 with respect to the knowledge about face masks and their proper use techniques. The healthcare team studied had satisfactory knowledge about face mask use techniques, and the study shed light on their unsatisfactory practices. Following instructions is very vital to protecting the person wearing the mask and preventing the spread of infection during health care by blocking droplets produced by speaking or coughing. Providing the healthcare teams with knowledge and experience about how to use face masks during the pandemic is critical to increase their awareness and practice in using face masks and prevent the infection from spreading.

Natural products such as domestic herbal drugs which are easily accessible and cost-effective can be used as a complementary treatment in mild and moderate COVID-19 cases. This study aimed to detect and describe the efficiency of phenolics detected in the galangal–cinnamon mixture in the inhibition of SARS-CoV-2’s different protein targets. The potential antiviral effect of galangal–cinnamon aqueous extract (GCAE) against Low Pathogenic HCoV-229E was assessed using cytopathic effect inhibition assay and the crystal violet method. Low Pathogenic HCoV-229E was used as it is safer for in vitro laboratory experimentation and due to the conformation and the binding pockets similarity between HCoV-229E and SARS-CoV-2 M^Pro. The GCAE showed a significant antiviral effect against HCoV-229E (IC₅₀ 15.083 µg/mL). Twelve phenolic compounds were detected in the extract with ellagic, cinnamic, and gallic acids being the major identified phenolic acids, while rutin was the major identified flavonoid glycoside. Quantum-chemical calculations were made to find molecular properties using the DFT/B3LYP method with 6-311++G(2d,2p) basis set. Quantum-chemical values such as EHOMO, ELUMO, energy gap, ionization potential, chemical hardness, softness, and electronegativity values were calculated and discussed. Phenolic compounds detected by HPLC-DAD-UV in the GCAE were docked into the active site of 3 HCoV-229E targets (PDB IDs. 2ZU2, 6U7G, 7VN9, and 6WTT) to find the potential inhibitors that block the Coronavirus infection pathways from quantum and docking data for these compounds. There are good adaptations between the theoretical and experimental results showing that rutin has the highest activity against Low Pathogenic HCoV-229E in the GCAE extract.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) has emerged as a global health challenge due to its complex pathophysiological processes. Systemic inflammation may profoundly affect disease progression, but the correlation between inflammatory markers and disease severity remains inadequately explored. This cross-sectional analysis within a prospective cohort evaluated associations of inflammatory markers (IL-6, TNF-α, hsCRP) with MASLD severity (five non-invasive scores) and metabolic indices, primarily with early-stage disease (66.7% mild fibrosis by TE). Methods: We recruited 120 patients diagnosed with MASLD. Assessment included anthropometric measurements, laboratory analyses, and non-invasive fibrosis evaluation using five validated scoring systems (APRI, FIB-4, NAFLD fibrosis score, FAST score, and transient elastography). Inflammatory markers were quantified using high-sensitivity ELISA techniques. Medication/comorbidities were recorded (statins 23.3%, diabetes drugs 26.7%), and multivariate regressions and FDR correction were applied. Results: Patients showed remarkably elevated inflammatory markers compared to reference ranges: IL-6 (15.1 ± 9.3 pg/mL), TNF-α (38.8 ± 29.1 pg/mL), and hsCRP (12.3 ± 11.1 mg/L). No correlations were found between inflammatory markers and disease severity across any non-invasive scoring system. However, TNF-α correlated significantly with waist circumference (r = 0.28, p = 0.002) and ALT (r = 0.19, p = 0.03), while showing inverse correlations with total cholesterol (r = −0.27, p = 0.03) and LDL (r = −0.22, p = 0.02). In contrast, hsCRP correlated positively with LDL (r = 0.20, p = 0.02) and WBC count (r = 0.24, p = 0.008). Conclusion: This study reveals a dissociation between systemic inflammatory markers and hepatic fibrosis severity in MASLD. Inflammatory Markers showed stronger metabolic associations than fibrosis, limiting their utility as fibrosis surrogates in early MASLD. These findings support a dual-pathway approach to MASLD management, targeting metabolic and hepatic components independently. The divergent associations of TNF-α and hsCRP with lipid profiles suggest distinct inflammatory mechanisms in MASLD.

Background and Objectives: Primary liver cancer is a major cause of mortality, ranking third among the most fatal cancers. In Egypt, liver cancer constitutes 11.75% of gastrointestinal malignancies, with HCC representing 70.5% of cases. The landscape of HCC management was revolutionized by locoregional modalities, which offer a comparable alternative to conventional techniques, with low complications and minimal invasiveness. RFA is a technique that is suitable for early-stage lesions in the liver, with a high overall survival and low complication rates. However, the associated complications cause potential mortality and morbidity. The proper selection of patients may avoid such complications. This study presents a five-year experience of radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) in Egypt, analyzing the predictors of complications and the computed tomography (CT) features associated with complications post-ablation. Materials and Methods: The study included 1000 cases (84% males with a mean age of 60), with 90% having HCC. Exclusion criteria included prior chemoembolization and non-HCC primary hepatic tumors. Patients underwent RFA at Cairo University Hospital and two private centers from January 2014 to January 2019. The workup involved clinical assessments, lab tests, and CT scans. Complications were classified as major or minor. Statistical analysis was conducted via SPSS software Version 22.0, with associations evaluated using a chi-square test. A decision tree was employed to determine the predictive values for different variables associated with the complications. Results: Overall, the rate of complications was 4%, and mortality stood low at 0.1%. Subcapsular lesions were associated with complications, as well as the lesion size, site, Child–Pugh classification, and the number of RFA sessions. Decision tree analysis determined the size of a lesion to be the most predictive factor of major complications, whereas the site of the lesion predicted the occurrence of minor complications. Conclusions: RFA offers low complication rates; however, precise patient selection is critical. The approach and imaging modality choice influence the outcomes. Clinician experience enhances early complication detection, thereby allowing for effective treatments.

Background: Multiple myeloma (MM) is a cancer of bone marrow (BM) that is caused by the clonal plasma cells which produce monoclonal immunoglobulin that cause manifestation such as hypercalcemia, pathological bone fracture, renal impairment, BM deficiency, and hyper viscosity. Interleukin 10 (IL-10) has anti-inflammatory effects by binding to IL-10R dependent signals on cell surface; if IL‐10 mutation affects cancer immunity so may be cause of many cancers including hematologic malignancies. Objective: To investigate role of IL-10 gene promoter (rs1800872) and its receptor beta (rs2834167) genotypes in (MM) patients on clinical presentation, laboratory findings, treatment response and outcome in a group of MM patients in Egyptian patients. Patients and Methods: The present study included 50 MM patients compared to 50 matched healthy individuals in age and sex with normal laboratory findings as a control group for analysis of single nucleotide polymorphisms (SNP) of IL-10 gene promoter (rs1800872), and IL‐10Rβ (rs2834167) genotypes using Real time- Polymerase Chain reaction (RT-PCR) technique. Results: The genotypes frequency distribution of IL-10 SNP (rs1800872), there was statistically significant difference between MM patient and the control groups (P- value 0.003) but not found as regard IL-10 RB (P –value 0.142).

Background: This study examines the clinical efficacy of daratumumab when combined with other therapeutic agents in patients with multiple myeloma, with a focus on key outcomes including overall response, progression-free survival (PFS), and stringent complete response (sCR). Methods: A systematic literature search was conducted using PubMed, Web of Science, Scopus, and the Cochrane Library. Statistical analyses were performed with R software (version 4.2.2). Between-study heterogeneity was assessed using the Cochrane Q test and the I² statistic, while potential publication bias was evaluated through Egger’s regression test and visual inspection of funnel plots. Results: The meta-analysis revealed that daratumumab-containing regimens were associated with a 54.4% reduction in the risk of disease progression or death (hazard ratio[HR] 0.4558; 95% confidence-interval [CI]: 0.4031–0.5154). Similar results were observed using a random-effects model (HR 0.4667; 95% CI: 0.3771–0.5776), despite moderate heterogeneity (I² = 66.7%). Moreover, patients treated with daratumumab were approximately 2.4 times more likely to achieve a stringent complete response (odds-ratio[OR] 2.38; 95% CI: 1.80–3.15), with moderate heterogeneity across studies (I² = 58.2%). Conclusions: Incorporating daratumumab into standard therapy for multiple myeloma significantly enhances progression-free survival and the rate of stringent complete response. Despite some heterogeneity, the consistent positive outcomes support its use as an effective treatment option in clinical practice.
