RESUMO

Background: Monkeypox (Mpox) is a re-emerging infectious disease representing a new global challenge. It poses a substantial threat to countries, particularly those with a low number of cases. Due to its popularity as a tourist destination and its proximity to many African refugees, Egypt is potentially at risk of Mpox importation. Therefore, effective disease management necessitates healthcare workers (HCWs) to possess adept knowledge, along with a positive attitude and behavior. The study aimed to assess the knowledge, attitude, and perception of Egyptian HCWs and medical students towards human Mpox. Methods: The present cross-sectional study data was collected from participants between October and December 2022 via a questionnaire. The questionnaire comprised 31 questions in the knowledge section, 11 questions in the attitude section, and 14 in the perception section. Results: The present study involved a total of 1,034 HCWs and medical students. It was found that 55.3% of the participants demonstrated adequate knowledge about Mpox, whereas 44.5% and 39.8% of the respondents exhibited favorable attitudes and perceptions towards the disease, respectively. Binary logistic regression analysis revealed that adequate knowledge was significantly observed in ages older than 40 years (p < 0.001), married participants (p < 0.001), and doctors (p < 0.001). The positive attitude was significantly observed among the male sex (p = 0.045), urban residents (p = 0.002), and nurses (p = 0.002). Conversely, married participants (p = 0.013), doctors (p < 0.001), and individuals employed in pharmacy and laboratory departments (p < 0.001) experienced an increase in positive perception. Conclusion: Knowledge, attitude, and perception towards Mpox among Egyptian HCWs and medical students exhibit suboptimal levels. Addressing these gaps is crucial to controlling and effectively preventing disease transmission.

RESUMO

Different strategies have been approved for controlling extended-spectrum ßeta lactamase (ESBL) producing uropathogenic bacteria. The antibacterial activity of Lactic acid bacteria (LAB) is an effective strategy due to its probiotic characteristics and beneficial effects on human health. The antibiotic susceptibility test, disk diffusion method, and double disc synergy test indicated that five enteric uropathogenic isolates were ESBL producers during the present study. They recorded diameters of inhibition zones as ≤ 18, ≤ 8, ≤ 19, and ≤ 8 mm against cefotaxime (CTX), ceftazidime (CAZ), aztreonam (ATM), and ceftriaxone (CRO). Genotypically, blaTEM genes are the most common, with (100 %) occurrence in all the five enteric tested uropathogens, followed by blaSHV and blaCTX genes (60 %). In addition, out of 10 LAB isolates from dairy products, the CFS of isolate no. K3 had high antibacterial activity against the tested ESBLs, especially no. U60, with a MIC of 600 µl. Additionally, the MIC and sub-MIC of K3 CFS inhibited the production of antibiotic-resistant bla TEM genes of U60. Analyzing the 16S rRNA sequence confirmed that the most potent ESBL-producing bacteria (U60) and LAB (K3) isolates were identified as Escherichia coli U60.1 and Weissella confuse K3 with accession numbers MW173246 and MW173299.1, respectively, in GenBank.

RESUMO

In cystic fibrosis individuals, chronic lung infections and hospital-acquired pneumonia are caused by Pseudomonas aeruginosa. P. aeruginosa generates siderophores such as pyoverdine (PVD) as iron uptake systems to cover its needs of iron ions for growth and infection. lasR quorum sensing (QS) gene has a crucial function in PVD production and biofilm generation in P. aeruginosa. Fifty isolates of P. aeruginosa were obtained from clinical specimens of sputum (collected from individuals suffering from pulmonary infections). Antibiotic sensitivity test was performed for 50P. aeruginosa isolates by using 10 different types of antibiotics. All isolates of P. aeruginosa showed resistance for all 10 using antibiotics in this study. Ten multidrug resistant isoloates of P. aeruginosa were selected for next tests. Virulence factors of ten multidrug resistant isolates of P. aeruginosa, such as biofilm generation, PVD production, and lasR gene were detected. From results, all 10P. aeruginosa isolates can produce biofilm, PVD, and contain lasR gene. The produced amplicon for the lasR gene was 725 bp. After mice injection by fresh and heated PVD produced by P. aeruginosa PS10 LC619328.2, the fresh PVD caused 100 % mortality within five days using 0.3 ml of its concentration (37.4 µM), while (15.3 µM) of heated PVD (toxoid) caused 50 % mortality.

RESUMO

Regulatory T (Treg) cells are the chief player in induction of autotolerance and the transcription factor, Forkhead Box P3 (Foxp3), is the master regulator of their development and function. Polymorphisms in Foxp3 locus affect Foxp3 expression and can influence Treg cell function. This study aimed to determine the frequency of -3279C/A and -924A/G polymorphisms in the promoter region of the Foxp3 gene in Egyptian rheumatoid arthritis (RA) patients in comparison to apparently healthy controls, to test their association with Foxp3 serum levels as well as with patients' clinical and laboratory features. Also, to evaluate Foxp3 serum level as a putative measure of Foxp3+ Treg cells-mediated immune regulation and disease activity. A total of 136 subjects (68 RA patients and 68 controls) were studied for determining the frequency of both -3279 C/A and -924 A/G polymorphisms in the Foxp3 promoter region by PCR-RFLP and measuring their Foxp3 protein serum levels by ELISA. Our results indicated that; -3279 Foxp3 CA and AA genotypes were significantly higher in patients than controls (OR (95% CI) = 2.86 (1.31-6.26) and 2.79 (1.11-7.07), P= 0.008 and p = 0.03, respectively). Similarly, -924 AG genotype was significantly higher in patients than controls (OR (95% CI) = 2.92 (1.35-6.34); P=0.006). A significantly higher risk of RA was associated with the Foxp3 polymorphic variants -3279 A and -924 G. There was a statistically significant elevation in Foxp3 serum levels among patients, which was positively correlated to disease activity score and disease grade. In conclusion, Foxp3 polymorphisms influenced the risk of developing RA, but did not influence disease severity or activity. Serum level of Foxp3 is not a reliable indicator of Treg-mediated immune regulation in RA patients.

RESUMO

Neutrophil gelatinase-associated lipocalin (NGAL) is emerging as a potential biomarker in many medical conditions including asthma. The aim of this study was to assess the role of serum NGAL in Egyptian childhood bronchial asthma. The study included 156 patients and 39 apparently healthy control children. Full clinical examination, pulmonary function tests; CBC, CRP, IgE, liver function tests, and renal function tests, and serum NGAL level were performed. The difference between the studied groups was statistically significant regarding IgE, eosinophils and NGAL (P= 0.001 for each). In addition, the difference between the subgroup with severe persistent asthma and the subgroup with mild intermittent asthma was significant (P=0.001). ROC curve analysis showed that at a cut-off value of 0.884 the sensitivity and specificity of differentiating severe bronchial asthma patients from controls was 82 % and 76 %, respectively. In conclusion, NGAL may represent a potential marker of bronchial asthma in children with severe disease.

RESUMO

PURPOSE: Quality of end-of-life (EOL) care is a key component of excellence in cancer care, and monitoring indicators for quality of EOL cancer care is crucial to providing excellent care. The aim of the current study is to describe the relative aggressiveness of EOL cancer care in the state of Qatar and to compare it with international figures. METHODS: We analyzed all deaths from cancer in Qatar between January 1, 2009 and December 31, 2013. A total of 784 eligible patients were studied to assess aggressiveness of cancer care at EOL. RESULTS: The average number of intensive care unit admissions per person decreased from 0.44 to 0.22 (P < .001) over the period of study. In addition, patients spent fewer days in the intensive care unit (2.79 to 1.82 days; P = .006) and made fewer visits to the emergency department (1.00 to 0.52 visits; P < .001) in the last 30 days of life. Fewer patients had at least one aggressive treatment measure at EOL during the 5-year period (82.3% to 71.0%; P = .038). The mean composite score for aggressiveness of EOL care decreased from 2.24 to 1.92 (P < .01). CONCLUSION: The aggressiveness of EOL cancer care has significantly decreased over time in Qatar; however, despite this decrease, the rate is still higher than that reported internationally. The integration of community palliative care services in Qatar may further decrease the aggressiveness of cancer care at EOL.

RESUMO

Integrons are genetic units characterized by the ability to capture and incorporate gene cassettes, thus can contribute to the emergence and transfer of antibiotic resistance. The objectives of this study were: (1) to investigate the presence and distribution of class I and class II integrons and the characteristics of the gene cassettes they carry in Enterobacteriaceae isolated from nosocomial infections at Zagzig University Hospital in Egypt, (2) to determine their impact on resistance, and (3) to identify risk factors for the existence of integrons. Relevant samples and full clinical history were collected from 118 inpatients. Samples were processed; isolated microbes were identified and tested for antibiotic susceptibilities. Integrons were detected by polymerase chain reaction (PCR) and were characterized into class I or II by restriction fragment length polymorphism (RFLP). Integron-positive isolates were subjected to another PCR to detect gene cassette, followed by gene cassette sequencing. Risk factors were analyzed by logistic regression analysis. Seventy-six Enterobacteriaceae isolates were recognized, 41 of them (53.9%) were integron-positive; 39 strains carried class I and 2 strains carried class II integrons. Integrons had gene cassettes encoding different combinations and types of resistance determinants. Interestingly, blaOXA129 gene was found and ereA gene was carried on class I integrons. The same determinants were carried within isolates of the same species as well as isolates of different species. The presence of integrons was significantly associated with multidrug resistance (MDR). No risk factors were associated for integron carriage. We conclude that integrons carrying gene cassettes encoding antibiotic resistance are significantly present among Enterobacteriaceae causing nosocomial infection in our hospital. Risk factors for acquisition remain to be identified.
