RESUMO
The identification of genes associated with resistance has the potential to facilitate the development of novel diagnostic tests and treatment methods. The objective of this study was to examine the antibiotic resistance and Fosfomycin resistance genes in uropathogenic Escherichia coli (UPEC) in patients in Baghdad, Iraq. After analyzing 250 urine samples using various identification methods, including the examination of morphological characteristics, biochemical tests, and genetic detection, it was determined that E. coli was the most common bacteria present, accounting for 63.6% of the samples. Antibiotic susceptibility testing showed a significant prevalence of resistance to various antibiotics, with 99.3% of E. coli isolates exhibiting multiple drug resistance (MDR). Fosfomycin showed antibacterial properties against UPEC. The minimum inhibitory concentration (MIC) ranged from 512 to 1024 µg/mL, while the minimum bactericidal concentration (MBC) was 2048 µg/mL. In the time-kill assay, fosfomycin was effective against fosfomycin-resistant isolates within 8-12 h. The genetic determinants associated with fosfomycin resistance were examined through the utilization of polymerase chain reaction (PCR). The findings indicated that the genes murA, glpT, and cyaA were detected in all the isolates when genomic DNA was used as a template. However, all the tests yielded negative results when plasmid was used as a template. The genes fosA3 and fosA4 were detected in 8.6% and 5% of the isolates when genomic DNA was used as a template. When plasmid was used as a template, the genes fosA3 and fosA4 were found in 5.7% and 2.9% of the isolates, respectively. In conclusion, there is an increasing problem with antibiotic resistance in UPEC, with elevated rates of resistance to several antibiotics. The study also offers novel insights into the genetic foundation of fosfomycin resistance in UPEC.

BACKGROUND AND AIM: The increasing incidence of Klebsiella pneumoniae infections, both in the community and in hospitals, is a huge health problem. This is due to the increasing resistance of the bacteria to antibiotics and biofilm formation, as well as the presence of a capsule. This study focuses on two main objectives: to survey the most common capsular types in local isolates for the first time in Anbar, Iraq, on molecular level and to distinguish between infectious pathogen strains using multilocus sequence typing (MLST) for more efficient epidemiological and surveillance analysis, in order to determine the source of these strains (invasive or purebred). METHODOLOGY: Multidrug-resistant (MDR) isolates adapted to genomic extraction and molecular screening of capsular type and MLST, and then to data processing by Pasteur Institut. RESULTS: For the first time, one isolate was registered as a new strain in the world with ST 6434; the other strains demonstrated as preregistered with ST16, ST218, and ST283. 33% of MDR isolates belonged to the capsular K2 type. CONCLUSION: The study's findings were not aligned with the global knowledge base about the distribution of capsular type in Asia. To prevent the spread of highly resistant strains, careful monitoring of virulence determinants is necessary in addition to the observation of antibiotic resistance.

On March 11, 2020, the World Health Organization (WHO) declared a new coronavirus infection caused by the SARS-CoV-2 virus as a pandemic, making it the 11th pandemic of the 20th and 21st centuries. This study investigated the clinical and laboratory results (D-dimer, conventional coagulation, and HbA1c biomarker concentrations) of 150 patients (75 male and 75 female) with confirmed COVID-19 pneumonia and 50 controls (25 male and 25 female). For disease diagnosis, all COVID-19 patients were given a Real-Time Reverse Transcription Polymerase Chain Reaction Assay (RT-PCR). The findings revealed that D-dimer and HbA1c levels in COVID-19 patients were significantly higher (P 0.001) at the time of admission; In COVID-19 patients, there was also a strong correlation between D-dimer levels and HbA1c levels (P 0.001). In conclusion, COVID-19 patients are more likely to have a poor prognosis if their D-dimer and HbA1c levels remain uncontrolled over a lengthy period. To lower the likelihood of a bad prognosis in COVID-19, patients with higher levels of D-dimer and HbA1c should be continuously monitored.
Em 11 de março de 2020, a Organização Mundial da Saúde (OMS) declarou uma nova infecção por coronavírus causada pelo vírus SARS-CoV-2 como uma pandemia, tornando-a a 11ª pandemia dos séculos XX e XXI. Este estudo investigou os resultados clínicos e laboratoriais (D-dímero, coagulação convencional e concentrações de biomarcadores HbA1c) de 150 pacientes (75 homens e 75 mulheres) com pneumonia por COVID-19 confirmada e 50 controles (25 homens e 25 mulheres). Para o diagnóstico da doença, todos os pacientes com COVID-19 receberam um Ensaio de Reação em Cadeia da Polimerase com Transcrição Reversa em Tempo Real (RT-PCR). Os achados revelaram que os níveis de D-dímero e HbA1c em pacientes com COVID-19 foram significativamente maiores (P 0,001) no momento da admissão. Em pacientes com COVID-19, também houve uma forte correlação entre os níveis de D-dímero e os níveis de HbA1c (P 0,001). Em conclusão, os pacientes com COVID-19 têm maior probabilidade de ter um prognóstico ruim se seus níveis de D-dímero e HbA1c permanecerem descontrolados por um longo período. Para diminuir a probabilidade de um mau prognóstico na COVID-19, os pacientes com níveis mais altos de D-dímero e HbA1c devem ser monitorados continuamente.

OBJECTIVE: The World Health Organization defines infertility as the inability to get pregnant after 12 months of unprotected sexual activity. This study was conducted to estimate the levels of gene expression for two mature miRNAs (i.e., miR-122 and miR-34c-5p) to evaluate susceptibility to male infertility. METHODS: This study included 50 male patients with idiopathic infertility who were admitted to hospital from the period November 2021 to May 2022 and another group consisting of 50 apparently healthy individuals used as controls. RESULTS: miR-122 level was significantly highest in azoospermia and followed by oligospermia, 39.22 (31.88) versus 37.34 (20.45), respectively. In addition, there was a very significant difference in miR-34c-5p levels between the study groups (p<0.05). CONCLUSION: Two miRNAs, namely, miR-34c-5p and miR-122, can be used as predictive and diagnostic biomarkers for infertility.

Purpose: To investigate the anesthetic effectiveness of buccal infiltration (BI) versus buccal plus lingual infiltration (BI+LI) of 4% articaine for intra-alveolar extraction of erupted mandibular molar teeth. Material and Methods: Eighty patients were included in this prospective clinical study. They were randomly divided into 1 of 2 equal groups: the 1st group received BI of 4% articaine 1.8 ml and LI of 0.5 ml, while the 2nd group received 4% articaine 1.8 ml BI plus 0.5 ml LI of normal saline. Another 1.8 ml articaine BI was given if initial anesthesia was inadequate. Outcome variables included pain, which was rated by patients at 3 intervals using visual analogue scale, and lingual anesthesia and patients' satisfaction which were measured using 5-score verbal rating scale. Data analyses used were descriptive statistics, t test, χ2 test, and Pearson's correlation coefficient. P-value value less than 0.05 was considered significant. Results: There were 46 females and 34 males and the mean age was 35.3 years. All outcome variables were comparable between the two study groups (pË0.05). Anesthesia was successful in 78% and 88% of cases in the (BI) and (BI+LI) groups respectively with no significant difference (p=0.2392). The mean articaine volume used was 2.5 ml and 2.87 ml respectively without significant difference (p=0.090). Conclusion: The anesthetic efficacy of (BI) alone and (BI+LI) of 4% articaine was comparable. When given in an adequate dose, articaine (BI) alone could be justified as an anesthetic option for the intra-alveolar extraction of mandibular molar teeth.
Objetivo: Investigar la efectividad anestésica de la infiltración bucal (BI) versus la infiltración bucal más lingual (BI+LI) de articaína al 4% para la extracción intraalveolar de molares mandibulares erupcionados. Material y Métodos: Ochenta pacientes fueron incluidos en este estudio clínico prospectivo. Se dividieron aleatoriamente en 1 de 2 grupos iguales: el primer grupo recibió BI de articaína al 4% 1,8 ml y LI de 0,5 ml, mientras que el segundo grupo recibió articaína al 4% 1,8 ml BI más 0,5 ml LI de solución salina normal. Se administró otro BI de articaína de 1,8 ml si la anestesia inicial era inadecuada. Las variables de resultado incluyeron el dolor, que los pacientes calificaron en 3 intervalos mediante una escala analógica visual, y la anestesia lingual y la satisfacción de los pacientes, que se midieron mediante una escala de calificación verbal de 5 puntos. Los análisis de datos utilizados fueron estadística descriptiva, prueba t, prueba χ2 y coeficiente de correlación de Pearson. Se consideró significativo el valor del valor de pinferior a 0,05. Resultados: Hubo 46 mujeres y 34 hombres y la edad media fue de 35,3 años. Todas las variables de resultado fueron comparables entre los dos grupos de estudio (p=0,05). La anestesia fue exitosa en el 78% y 88% de los casos en los grupos (BI) y (BI+LI) respectivamente sin diferencia significativa (p=0,2392). El volumen medio de articaína utilizado fue de 2,5 ml y 2,87 ml respectivamente sin diferencia significativa (p=0,090). Conclusión: La eficacia anestésica de (BI) solo y (BI+LI) de articaína al 4% fue comparable. Cuando se administra en una dosis adecuada, la articaína (BI) sola podría estar justificada para la extracción intraalveolar de molares mandibulares.

Despite vaccine development and vaccination programs underway around the globe, the coronavirus disease 2019 (COVID-19) pandemic has not been controlled as the SARS-CoV-2 virus is evolving and new variants are emerging. This study was conducted to sequence and molecularly characterize the representing samples from the early fourth SARS-CoV-2 wave in Iraq. Here, we have performed next-generation sequencing of whole-genome sequencing of two representing samples from the country's early beginning of the fourth pandemic wave. The samples were sequenced using Illumina Miseq system, and the reference sequences were retrieved from GISAID database. Phylogenetic analysis was performed through Mega software. This study provides an initial sequence analysis and molecular characterization of the first Omicron variant cases recorded in the country. Our analysis revealed many mutations on the spike glycoprotein, especially on the receptor binding domain, with potential impact on immune escape and infectivity. The study findings suggest considering the highly mutated immunogenic epitope of the Omicron variant as a reference for developing a new vaccine for combating the ongoing pandemic.
