Thr399Ile Polymorphism of Toll-Like Receptor 4 Gene and COVID -19 Severity in Samples of Iraqi Patients: Baghdad Province
type: item
description: Background: Toll-like receptor 4 (TLR4) is a pattern recognition receptor involved in the innate immune response, capable of recognizing certain molecular patterns found in bacteria and viruses, including the severe acute respiratory syndrome coronavirus 2 (SARS–CoV2) virus responsible for Corona virus disease 2019 (COVID-19). Objective: To investigate the potential relationship between the severity of COVID-19 and a specific genetic variation in the TLR4 gene known as Thr399Ile. Methods: A cross-sectional study conducted on 90 patients with COVID-19 in Baghdad. The researchers genotyping of Thr399Ile polymorphism in DNA extracted from blood samples of patients was done using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) analyses. Results: Two genotypes were found CC and CT, and no patients exhibiting the TT genotype. The CC genotype was associated with a DNA fragment size of 407 base pairs, while the CT genotype showed a size of 378 + 29 base pairs. In the non-severe infection group, the CC genotype frequency was 95.55%, while the CT genotype frequency was 4.44%. In the severe infection group, the CC genotype frequency was 93.33%, and the CT genotype frequency was 6.66%. This indicates no significant association between Thr399Ile polymorphism and COVID-19 severity. Thr399Ile mutant allele frequency among the 90 COVID-19 patients was found to be 5.5% (5 out of 90). Conclusion: Functionally effective Thr399Ile polymorphism of TLR4 gene have apparently no inﬂuence on the individual susceptibility for COVID-19 severity infection.

Lumbar Spine MRI Signal Intensity Measurements in The Assessment of Abnormal Bone Mineral Density in Postmenopausal Women
type: item
description: Background: Osteoporosis is characterized by low bone mass and micro-architectural deterioration. Objective: To measure a quantitative magnetic resonance imaging (MRI)-based score (M-score) for the diagnosis of abnormal bone mineral density in postmenopausal female and compare the results with standard control taking dual-energy x-ray absorptiometry (DEXA) scan measurements as a reference. Methods: This case-control study was conducted with 50 postmenopausal females who underwent DEXA exam for back pain. Another 50 healthy young females aged 20-29 years were used as a control group, and an MRI of the lumbar spine was done to all participants. From sagittal T1-weighted spin-echo sequence, Signal to noise ratio of L1-L4 was measured to all patients and controls and used to obtain M-score. Results: DEXA revealed that 19 patients had a normal T-score, 14 patients had osteopenia, and 17 patients had osteoporosis (mean T score -1.737), M-score were significantly higher among cases than controls (P = 0.0001). The SNR L1–L4 and M-score are negatively correlated to T-score (r = -0.864; P = 0.0001) and bone mineral density (BMD) (r = -0.863; P = 0.0001). The receiver operator characteristic (ROC) analysis revealed an M-score threshold of 2.63434 with 88.2% sensitivity and 78.8% specificity (P = 0.0001) for the discrimination of osteoporotic from non-osteoporotic females. For distinguishing normal from low-BMD patients, the ROC curve estimated an M-score threshold of 1.34413 with 100% sensitivity and specificity (P = 0.0001). According to the calculated M-score, 19 patients were normal (M-score &lt;1.334), 9 patients found to have osteopenia (M-score 1.334 - 2.634), and 22 osteoporotic patients (M-score &gt;2.634). Conclusion: M-score obtained from T1WI sequence of lumbar spine study is a useful quantitative method for the diagnosis of osteoporosis and osteopenia in postmenopausal females as compared to DEXA scan. The best cut off value for osteoporosis is 2.634. The best cut …

Significance of Combined Use of Natriuretic Peptides and Neutrophil Gelatinase-associated Lipocalin for Diagnosis of Renal Failure and Type 2 Diabetes Mellitus
type: item
description: Background: Both natriuretic peptides, NPs (BNP and CNP), and neutrophil gelatinase-associated lipocalin (NGAL) were reported to rise in chronic kidney disease (CKD) and type2 diabetes mellitus (T2DM). Their role in detecting and follow up of these two diseases has been well elucidated. Objective: To evaluate the use of a combination of NPs and NGAL in detecting renal insufficiency (per se) or early diabetic nephropathy. Methods: The study included 40 patients with CKD (mean age 50.63±9.25 years), 41 patients with T2DM (mean age 53.66±8.32 years) and 38 apparently healthy normal subjects (mean age 52.42±8.81 years) as controls. Natriuretic peptides, and NGAL were measured by enzyme linked immunosorbent assay (ELISA), and glycated hemoglobin (HbA1c) by fully automated boronate affinity assay. Renal function tests, glucose, and electrolytes were estimated by routine laboratory methods. Results: There was an increase in NGAL, N-terminal pro-C-type natriuretic peptide (NT-proCNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) in both groups of patients. The HbA1c was high in the T2DM group only. Receiver operating characteristic (ROC) curve revealed good sensitivity and specificity when using NGAL and NT-proBNP to discriminate between CKD and T2DM or between CKD and controls, or T2DM and controls. Conclusion: Combined use of NGAL and NT-proBNP in T2DM may be a better diagnostic marker for an early deterioration in renal function of diabetes mellitus than the HbA1c level alone.

The Role of Tumor Necrosis Factor-Alpha and C-C Motif Chemokine Ligand 3 Serum Levels in Some Iraqi Colorectal Cancer Patients
type: item
description: Background: The second leading cause of cancer-related death globally, colorectal cancer (CRC) is the malignant neoplasm with the third highest diagnosis rate. It is the primary cause of cancer-related morbidity and mortality in Iraq and ranks second in terms of frequency of death after cardiovascular disorders. An inflammatory cytokine called tumor necrosis factor-alpha (TNF-α) plays a critical role in the immune response and may contribute to CRC development. Patients with CRC who had elevated serum levels of C-C motif chemokine ligand 3 (CCL3) had a worse prognosis than those who had low levels of this chemokine. Objective: To evaluate the role of TNF-α and CCL3 in CRC patients by assessing the serum level estimation of TNF-α and CCL3 in addition to the demographic data analysis. Methods: The study has been approved by the College of Medicine, Al-Iraqia University and included 100 samples from male and female patients from the Medical City, Al-Imamein Al-Kadhimein Medical City, Al-Amal Hospital, and also from Al-Bilad Private Hospital suffering from problems in the colon and rectum. The study lasted for five months (from November 2023 until March 2024). The participants were divided into 2 groups: the 1st one contained CRC patients, while the 2nd contained colorectal problems other than CRC. Five ml of blood was taken from each participant for estimation of TNF-α and CCL3 serum level by using enzyme-linked immunosorbent assay. Demographic data were collected from the study participants (such as age, gender, address, and medical history). Ten samples were discarded due to hemolysis. Results: The serum levels of TNF-α and CCL3 in CRC patients showed a higher significant difference (P &lt;0.05) compared with the 2nd group. Conclusion: TNF-α and CCL3 significantly appeared as indicators for the progression of CRC cancers. Keywords: TNF-α, CCL3, colorectal cancer Citation: Abdulhamid AQ, Abdullah AR.

Investigating Serum LDH in Iraqi Patients Undergoing Dialysis for Chronic Kidney Disease
type: item
description: Background: Chronic kidney disease (CKD) has emerged as a prominent cause of mortality, following cardiac disease and cancer, exhibiting a substantial surge over the past two decades. One biochemical indicator that reflects cellular damage is lactate dehydrogenase (LDH), a key intracellular enzyme involved in the interconversion of pyruvate and lactate during glycolysis. Under normal conditions, LDH remains confined within cells; however, tissue damage can lead to its release into the bloodstream, resulting in elevated serum levels. Objective: To assess the LDH in CKD patients compared with healthy control. Methods: A total forty (40) patient with CKD were studied among them twenty (20) female and twenty (20) male patients and forty (40) healthy as controls, of them were eighteen (18) females and twenty-two (22) males. Their ages (patients and controls) were ranged from (18-70). Blood samples were collected from patients and control to evaluate serum levels of serum LDH and evaluate the routine markers (urea, creatinine, alanine aminotransferase (ALT), aspartate aminotransferase (AST), and this was done by spectrophotometry. Results: This result showed the LDH levels in the patients were significantly higher (224.64±113.39 U/L) than in the control group (176.26±38.99 U/L) (P = 0.014). ALT and AST levels in the patients were lower than in the control group, but the difference was not statistically significant for ALT (P = 0.132) and was significant for AST (P = 0.03). The urea, and serum creatinine levels in the patients were all significantly higher than in the control group (P &lt;0.001). Conclusion: Serum LDH levels were significantly elevated in CKD patients undergoing hemodialysis compared to healthy controls, suggesting that LDH may serve as a useful biomarker for tissue damage and disease severity in patients with CKD.

type: item
description: Background: The Gamma Knife (GK) is a radio surgical method to treat malignant and benign brain tumours, atrioventricular malformations (AVM), and functional disorders. Objective: To investigate the tumor shrinkage after six months of GK with hypofractionation. Methods: A study at Dr. Saad Al-Witry Hospital for Neurosciences and Al-Altaj Hospital involved 50 patients with large brain tumors. Each patients underwent a magnetic resonance imaging and computed tomography images before and after treatment. Results: The mean dose distribution was higher in metastasis. After irradiation, gliosis around the tumor was observed, with 86% showing a positive response to radiation treatment. The results of tumor shrinkage were classified according to the number of treatment fractions, with highly significant shrinkage observed in those treated in three fractions and those treated after four fractions. Conclusion: The hypo fractionated GK appears to be a viable and effective method of treating various brain tumors that are benign or malignant. The method has a favorable outcome that involves both a decrease in tumor size and a minimum of side effects.

type: item
description: Background: Psoriasis is a protracting disorder of the skin that is immune mediated with a prolapsing characteristic making it difficult to fully treat. Objective: To investigate the effect of Myricetin in Imiquimod induced-psoriasis in mouse model and its possible therapeutic effect. Methods: Twnety-eight albino mice were randomly divided into 3 groups, 1st group involved healthy mice did not receive any medication, 2nd group (induction group) received only topical Imiquimod, and the 3rd group involved mice that received a topical Myricetin 10% ointment. All the mice received the test substances on the shaved back for 7 consecutive days and scoring for skin inflammation severity (scaling, erythema and thickness) was recorded on daily basis, and the animals were sacrificed on day 15. Skin samples were collected to evaluate the histopathological scores (Baker\&#039;s and Psoriasis area and severity index (PASI), in addition to measurement of tissue inflammatory biomarkers Interleukin (IL)-10, IL-17, tumor necrosis factor- alpha (TNF-α) and vascular endothelial growth factor (VEGF) by enzyme-linked immunosorbent assay (ELISA). Results: Psoriasis induction was successful by Imiquimod, and psoriasis like lesions developed on the skin and decreased the IL-10 and increased levels of other studied biomarkers. Topical Myricetin showed a significant increase in IL-10 levels (P &lt;0.001) and a significant reduction in TNF-α (P &lt;0.001), VEGF (P &lt;0.05) and IL-17 levels (P &lt;0.001). There was also a significant reduction in Baker\&#039;s score and PASI. Conclusion: Topical Myricetin possesses anti-psoriasis activity and could be used successfully for the alleviation of psoriatic symptoms and further studies of the skin inflammatory diseases.

Exploring the Correlation Between Tyrosinase Enzyme Levels and the Severity of Melasma in Women: A Case-Control Study in Baghdad
type: item
description: Background: Melasma is a skin condition that disrupts the skin on the face. Tyrosinase enzyme (TYR) increase and decrease the antioxidants naturally produced in the body, leading to melasma. TYR is a key enzyme in melanogenesis. Tyrosinase\&#039;s various mechanisms are enhanced by genetic, environmental, and endocrine factors. Objective: To investigate the relationship between serum TYR enzyme levels and the severity of melasma as a biomarker for diagnosis and treatment. Methods: A case-control study was executed during the term of March to October 2023. The study included 60 patients with melasma and 60 control participants, all female, ranging in age from 20 to 50 years. All participants were examined using Wood\&#039;s light. Blood samples were collected from each individual, and sera were used after separation to measure TYR by enzyme-linked immunosorbent assay (ELISA) method levels in different stages of melasma severity. Results: Increased concentration TYR with different stages of severity (7.36±0.19 U/ml) compared to the control (3.89±0.08 U/ml) utilizing an independent t-test. Additionally, the serum TYR levels significantly increased as the severity of melasma increased. Furthermore, the one-way ANOVA test indicated substantial serum TYR level and melasma area and severity index (MASI) scores for mild, moderate, and severe were 6.19±0.1 U/mL, 7.69±0.07 U/mL, and 9.38±0.31 U/mL, respectively. These results strongly suggest that TYR plays a crucial role in the formation and progression of melasma. Conclusion: The result of this study refers to a significant correlation between the level of TYR and the degree of melasma.

From Virome to Biomarker: Insights into the Role of Torque Teno Virus in Health and Ecosystems
type: item
description: In virology, the term ‘virome’ refers to commensal viruses that typically replicate and persist within healthy individuals, without causing harmful effects to the host; this concept is familiar to microbiologists. Torque Teno Virus (TTV) is one of common commensal viruses which is very ubiquitous in the environment and infects both humans and animals. Multiple modes of transmission of TTV enhance the spreading of these viruses within ecosystems and infect new hosts. Recently, TTV has emerged as a promising biomarker for medical and environmental applications. This review article examines the widespread presence of the TTV and discusses its potential as a biomarker for exciting future uses. Also, explore the extensive global distribution of TTV, highlighting the intriguing variations in its frequency observed across diverse populations. By inspecting the factors contributing to these disparities, including geographical location, and host demographics, this review sheds light on the enigmatic nature of TTV’s prevalence.

Phage Therapy for Treatment of UTI Caused by Multi-Drug-Resistant E. coli in Vitro and in Vivo Study
type: item
description: Background: Multidrug-resistant (MDR) bacteria cause a substantial health burden. Escherichia coli (E. coli) is one of the most common causative agents of bacterial infections in urinary tract infection (UTI) and emergence of multidrug resistant E. coli is a major public health threat worldwide. In this respect, recent studies have proposed bacteriophage (phage) therapy as a potential alternative therapy to antibiotics for treating MDR bacteria. Objective: To evaluate the potential of bacteriophage therapy to treat a drug-resistant UTI caused by E. coli in rabbits. Methods: This study was carried out during the period from September 2019 to February 2021 in Kirkuk Province. A total of 30 bacterial isolates of E. coli were collected from bacteriology isolated - clinical specimens. Full diagnostic procedures were conducted to confirm the diagnosis of E. coli; moreover, antibiogram was done to identify MDR E. coli isolates. Lytic phages were isolated using phage amplification assays. Phage cocktail was prepared accordingly. Rabbit animals with induced UTI were orally fed with E. coli specific phage cocktail. Phages and E. coli bacteria were isolated from urine of rabbits for evaluating the success rate of phage therapy. Results: It was shown that four bacteria isolates did establish specific lytic phages for E coli. Orally-fed phages to E. coli were isolated from the urine of rabbits and peaked at the second day with continuous decline in titer over the third and fourth days after phage administration. The average titer plaque-forming unit/ml (PFU/ml) for E. coli specific phages was 46, 15 and 1 at the second, third and fourth days. Regarding the in vivo activity of phage on bacterial growth, the bacterial count in urine was shown to decline remarkably after 24 hr till 4 days after the oral administration of lytic phages. The decline in bacterial count in urine was highly significant and reached up to 7-8 log. Conclusion: Phage cocktail therapy was shown to be effectiv…

Objective: To quantify the prevalence of yersinobactin irp2, salmonellochilin iroN, and aerobactin iucA siderophore genes in the virulent Iraqi strains of uropathogenic Escherichia coli (UPEC). Methods: Fourteen E. coli strains that were previously isolated and diagnosed from urinary tract infections and biologically active siderophore producers. These strains were analyzed for the presence of three siderophore genes (iucA, iroN, and irp2) using conventional polymerase chain reactions (PCR). Results: The frequencies of such iucA, iroN, and irp2 genes among the UPEC isolates were 3 (21.42%), 10 (71.4%), and 4 (28.6%), respectively. Conclusion: Research suggests that siderophores can successfully reduce the pathogenicity of UPEC bacteria. Moreover, their primary function in infection differs depending on the siderophore type and concentration. Yersinobactin irp2 represented the main siderophore gene, followed by salmochelin iroN and aerobactin iucA.

Ocular Hypotensive Effects of Nesiritide 0.005% Eye Drops on Ocular Normotensive and Betamethasone-Induced Ocular Hypertensive Rabbits
type: item
description: Background: The only method to stop the progression of glaucoma is to decrease intraocular pressure (IOP). Nesiritide is a natriuretic peptide that is effective in reducing blood pressure via his vasodilator action, which may be effective in reducing IOP. Objective: To evaluate the efficacy of nesiritide 0.005% eye drops on IOP of ocular normotensive and betamethasone-induced ocular hypertensive rabbits in comparison with that of latanoprost 0.005% eye drops; besides, to study the safety profile of nesiritide eye drops. Methods: This study included 36 male rabbits; 18 rabbits represented the ocular normotensive groups (control, latanoprost, and nesiritide) and the other 18 rabbits represented betamethasone-induced ocular hypertension groups (vehicle, latanoprost, and nesiritide). Tested drugs instilled as one drop twice daily for 7 days in normotensive and hypertensive left eye. The IOP was measured with the aid of Schiötz tonometer. Other examined parameters were pupil diameter, light pupillary reflex, corneal sensation reflex, and conjunctival redness which were recorded before starting the experiment and then daily before and after drug application for one week. Results: This study revealed that nesiritide eye drops significantly reduced IOP since the 3rd day in both normotensive and steroid-induced ocular hypertensive model; yet, this effect was less potent than that of latanoprost eye drops. Nesiritde eye drops did not induce significant changes in the other examined parameters. Conclusion: This study revealed the efficacy and apparent safety of nesiritide 0.005% eye drops in lowering IOP in both ocular normotensive and betamethasone-induced ocular hypertensive rabbits.

Comparative Diagnostic Efficacy of 3D vs 2D T2-Weighted MRI in Assessing Lumbar Spine Pathologies
type: item
description: Background: Magnetic resonance imaging (MRI) detects soft tissue pathologies and lumbar disc illnesses such as bulging, herniation, spinal stenosis, and vertebral abnormalities. Three-dimensional (3D) isotropic MRI provides several benefits over two-dimensional (2D) turbo spin-echo sequences for musculoskeletal imaging. Objective: To compare the image quality of 2D T2-weighted turbo spin-echo (2D T2W TSE) sequences to 3D T2-weighted turbo spin-echo (3D T2W TSE) sequences and estimate how physical parameters of patients, including age and sex, may impact the outcome of medical imaging. Methods: Seventy patients with lumbar spine problems (mean age below 50) were examined. MRI scans were obtained with 2D T2W TSE and 3D T2W TSE sequences. Parameters assessed included image contrast, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and signal intensity, calculated using a region-of-interest tool. Results: The findings demonstrated that 2D T2W TSE images exhibited significantly higher mean (230.59±64.4) signal intensity values, and greater signal intensity variability (2.92±0.61) than 3D T2W TSE images. Conversely, 3D T2W TSE images outperformed their 2D counterparts in signal-to-noise ratio (82.93±31.51) and contrast-to-noise ratio (40.55±14.95). A strong negative correlation was observed between age and both the mean signal intensity and SNR in 2D T2W TSE images. No significant association was found between age and any characteristics of 3D T2W TSE images. Furthermore, sex showed no significant correlation with any features of 2D or 3D T2W TSE images. Conclusion: The research found increased signal intensity in 2D T2W TSE images and higher SNR and CNR in 3D T2W TSE images. These data imply that age may affect signal intensity measures from 2D T2W images, lowering image quality in older individuals. The lack of a significant link between age and 3D T2W TSE parameters shows that age-related changes may not impact 3D T2W TSE images. Keywords: Magnetic resonance…

The Evaluation of Gamma Knife Indices for Treatment Planning (Single Session, Multi-Session, and Hypofractionation) for Gamma Knife Radiosurgery in Patients with Meningioma
type: item
description: Background: Meningiomas are the most common benign intracranial tumors, making up about one-third of all primary brain tumors, some can cause issues due to difficult removal in sensitive or hard-to-reach areas. Gamma knife radiosurgery (GKR) is an effective treatment for meningioma. Objective: To assess better planned treatments, such as multisession and hypofractionation, as well as single session stereotactic radiosurgery. Methods: Fifty-two patients with meningiomas, diagnosed by neurosurgeons or oncologists, participated in a cross-sectional study at Saad Alwitry Hospital’s Gamma Knife Center. Gamma Knife therapy was administered by a specialist, with computed tomography (CT) and magnetic resonance imaging (MRI) used to evaluate the tumor characteristics. The dosimetry parameters used in this study are coverage, selectivity, gradient index (GI), and time (minutes). These parameters are obtained for each plan session. Results: There were significant differences in the mean value of selectivity between the three groups, with the highest value among the patients who received multi-session doses of GKR (Gy) than those who received single and hypo sessions of GKR (Gy). The results also revealed non-significant and slight differences in the mean values of the GI between patients who received multi, single, and hypo sessions. Patients who received multiple sessions required fewer mean values of GKR shot numbers. This study also found that patients who received hypo-session GKR required less time (minutes) for gamma knife radiation therapy. Ultimately, the results showed the differences in tumor size (cm3) before and after GKR treatment according to doses given in the three sessions. Conclusion: Multisession GKR therapy offers a low-morbidity alternative that is secure, efficient, and well tolerated for these large lesions. The meningioma multisession GKR is successful in reducing the size of large tumors. Keywords: Gamma knife, stereotactic radiosurgery, coverage, sele…

The Frequency of Bk Polyomavirus Viruria in A Sample of Iraqi Children with Acute Lymphoblastic Leukemia
type: item
description: Background: BK Polyoma virus (BKPyV) is a ubiquitous virus and infect children at early age and becomes latent and it has been found as the main cause of hemorrhagic cystitis in hematopoietic stem cell transplantation patients, due to immunosuppression regimen that led to the activation of the virus from the latency status and lead to increased viral shedding in urine. Objective: To find the frequency of BKPyV-DNA in urine (viruria) among acute lymphoblastic leukemia (ALL) patients as compared to healthy controls and compare it with age, sex, relapse and leukocytes level. Methods: Urine samples were collected from 60 ALL patients, and 60 apparently healthy age and sex-matched children who were taken as a control group. The BKPyV-DNA in urine (viruria) was detected using real time polymerase chain reaction and Pap-stained urine cytology smears were checked to identify the presence of decoy cells (DCs). Results: The BKPyV-DNA was detected in the urine of all patients (100.0%) and in 55.0% of control group (P &lt;0.001) and all the patients were DCs negative. There was no significant effect of the positivity of viruria on neither leukocytes level nor on the occurrence of relapse in leukemia patients. Conclusion: The very high frequency of BKPyV-DNA in urine (viruria) indicates the importance of reactivation of this virus in ALL patients with and without chemotherapy.

Ultrasound-Assisted Synthesis of Iron Oxide Nanoparticles: Application in Cytotoxicity and Antibacterial Activity
type: item
description: Background: The rapid emergence of antibiotic resistance among various bacterial species has necessitated the development of alternative therapeutic options. Nanotechnology, particularly the production and surface modification of metal nanoparticles (MNPs), has gained significant attention as a promising approach in combating antibiotic resistance. Objective: To explore a safe and cost-effective method for synthesizing iron oxide nanoparticles (IONPs) with unique shapes through ultrasound-assisted co-precipitation and to use it as a potential solution to the problem of antimicrobial-resistant bacteria especially multidrug-resistant bacteria. Methods: IONPs were synthesized using an ultrasound-assisted method and characterized with techniques such ultraviolet-visible spectrophotometry (UV-Vis), energy dispersive of X-ray spectroscopy (EDX), X-ray diffraction (XRD), atomic force microscopy (AFM), zeta potential analysis, transmission electron microscopy (TEM), and scanning electron microscopy (SEM). Antimicrobial activity was assessed using minimum inhibitory concentration (MIC) tests at 16 μg/ml and a well diffusion assay against Gram-negative bacteria and Gram-positive bacteria. Results: IONPs had an average diameter size of 30 nm, displaying a spherical shape. At concentration of 16 μg/ml, the NPs was found to exhibit a MIC and displayed potent antimicrobial activity against wild-type multidrug-resistant strains of both Gram-positive and Gram-negative bacteria in vitro. Moreover, in vivo experiments showed that the IONPs led to a significant decrease in urothelial bladder cancer (UBC)-40 cell. Conclusion: The US-assisted method utilized in this research for the synthesis of IONPs has proven to be suitable for producing IONPs with precise particle size and high product homogeneity.

type: item
description: Background: In scoliosis surgery, intraoperative somatosensory evoked potential (SSEP) monitoring has reduced the incidence of postoperative neurologic deficits. Many intraoperative environmental and systemic factors affect the amplitude and latency of SSEP waves during surgery. Objective: To assess the role played by SSEP during spinal surgery in preventing postoperative neurologic deficits. Methods: Pre-, intra- and postoperative tibial SSEP recorded in 51 patients with scoliosis undergoing surgical correction were analyzed. Recorded parameters include the P37 and N45 latencies and amplitudes. Results: The intraoperative tibial SSEP latencies were significantly prolonged and intraoperative amplitudes were significantly reduced in comparison to baseline recordings. There was highly significant increase in the mean latency of alarm readings of tibial P37 and N45 waves from baseline. Likewise, there was statistically highly significant decrement in the mean amplitude of the alarm readings of tibial P37 and N45 wave from baseline. Pre- and postoperative latencies and amplitudes were compared; the differences were not significant. Conclusion: The intraoperative SSEP neuromonitoring is valuable in the prevention of neurological injury during surgical procedures.

SARS-COV-2 Prevention Strategy Receptor Binding Domain Loaded with Chitosan Nanoparticles Enhance Antibody Production
type: item
description: Background: Corona virus disease 2019(COVID-19), caused by the severe acute respiratory syndrome virus (SARS-CoV-2), heavily relies on the angiotensin-converting enzyme 2 (ACE2) receptor for cell entry. The receptor-binding domain (RBD) of the virus plays a critical role in this process and is considered a key target for neutralizing activity. The RBD can be produced efficiently and effectively to induce a neutralizing immune response. Chitosan (CS), a widely used vaccine adjuvant, shows promise as an adjuvant/carrier in vaccine delivery. Objective: To investigate the potential of CS nanoparticles (CS-NPs) as an alternative adjuvant to stimulate specific anti-RBD IgG antibody production efficiently and with reduced toxicity compared to alum. Methods: Antigens were prepared by loading RBD protein onto CS-NPs, followed by measuring the released RBD protein using high-performance liquid chromatography. Rabbits were vaccinated, and the resulting antibody response was detected using competitive enzyme linked immunosorbent assay. Results: The use of CS-NPs as an adjuvant loaded with the RBD antigen demonstrated the ability to induce a substantial titer of anti-RBD IgG antibodies when administered to rabbits over a course of three doses with two-week intervals. Comparatively, using alum as an adjuvant resulted in higher antibody titers with the same vaccination schedule. Conclusion: It was observed that CS-NPs as an adjuvant could efficiently stimulate specific anti-receptor-binding domain IgG antibodies while exhibiting less toxicity compared to alum Keywords: SARS-CoV-2, vaccine adjuvant, chitosan nanoparticles, RBD, specific IgG antibody.

Skin Diseases in A Sample of Under-Five Years Children and their Sociodemographic Characteristics at Al-Imamein Al-Kadhimein Medical City/Baghdad
type: item
description: Background: Skin diseases are a big health problem affecting a high percent of the population and causing distress and disability. Children\&#039;s skin is often regarded as smoother and softer than that of adults; as a result, it may be more susceptible to irritation and inflammation. Objective: To determine frequency and types of skin diseases in children less than 5 and to find some sociodemographic characteristics of those children. Methods: A cross-sectional study conducted in Al-Imamein Al-Kadhimein Medical City; the data were collected during March and April 2019. A convenient sample (262 under 5 years of age children) were selected from dermatological outpatient’s clinic by interviewing the parents of those children. Results: Out of this sample, 144 (55%) were males; atopic dermatitis in 79 (30.2%) constituted the highest percentage followed by diaper rash in 46 (17.5%) and warts were found in 28 (10.7%). Regarding their sociodemographic characteristics, 199 (76%) and 209 (80%) of the children starting solid food and bottle feeding less than 4 months age, respectively and 224 (85.5%) of the children were up-to-date vaccination. Conclusion: Atopic dermatitis was the most frequent skin diseases in children under 5 years. Most of them were males, starting solid food and bottle feeding before 4 months. More than two third were taking their vaccination up to date. Keywords: Skin diseases, under 5 years, Baghdad, atopic dermatitis and sociodemographic Citation: Hussain NA, Alogaili MH, Mohammed LK.

Banknotes as a Potential Source of Transmissible Diseases in the Al-Anbar Governorate, Iraq
type: item
description: Background: Banknotes are handled by individuals with varying health and hygiene practices and are stored under diverse environmental and personal conditions. Paper currency is widely exchanged for commercial transactions and services, making it a potential vector for the transmission of bacteria. Objective: To evaluate the bacterial contamination of banknotes in circulation in the Al-Anbar Governorate, Iraq. Methods: The study was done between February and April 2023 and analyzed at the Microbiology Laboratories of the College of Medicine, University of Fallujah. A total of 84 samples were collected from seven banknote denominations across four locations. The bacteria were isolated and then identified by VITEK-2 then the antibiotic susceptibility test was done. Results: Among the locations, the butcher shop had the highest number of positive samples 23 (32.1%), followed by the grocery store 21 (29.1%) and Rafidain Bank 18 (25%), while the pharmacy 10 (13.8%) had the fewest. Bacterial identification revealed a predominance of Gram-negative isolates over Gram-positive bacteria. The number of colony-forming units correlated with the locations of positive samples, with the grocery store being the most contaminated. Antibiotic susceptibility testing indicated that while antibiotics such as Imipenem and Ciprofloxacin may remain effective, significant resistance was observed for Ceftriaxone. Conclusion: The study found that currency used in daily life may be a source of bacterial infection. The exchange of banknotes among individuals with different hygiene practices and occupations may facilitate the spread of diseases through contaminated currency.

Fatal Methamphetamine Poisoning: Forensic Case Presentation
type: item
description: Background: The rising number of methamphetamine abusers and the consequent fatalities prompted this case presentation, aiming to highlight the risks associated with its use and to enhance awareness of its detrimental effects on the human body. Case presentation: The study examined a 30-year-old male who was discovered deceased at his home in the early morning. The autopsy showed no evidence of external or internal trauma and significant gross pathological alterations. A small torn nylon package was found in the stomach\&#039;s lumen, its contents released. Toxicological tests of the stomach contents, blood, and urine identified methamphetamine in the package. Laboratory results indicated a lethal concentration. The liver tissue exhibited sinusoidal cholestasis, and the kidneys displayed severe acute renal tubular necrosis. Conclusion: The study highlights the toxic and irreversible impact of methamphetamine on different human organs and the lethal consequences of smuggling the substance through oral ingestion.

The Potential Role of BK and JC Polyomaviruses in Urothelial Cancer
type: item
description: Background: BK and JC polyomaviruses are perceived as the two most common human polyomaviruses (HPyVs). These two viruses inhabit the epithelial surfaces of the bladder and kidney as the primary site of replication and latency. There have been multiple evidences on the association and implication of some of the HPyVs in human cancerous growth, indicating an etiological association with carcinogenesis. Objective: To explore the association and implication of some of the polyomaviruses in urothelial carcinomas. Methods: Tissue biopsies were collected from 103 patients with urothelial carcinoma. The biopsies were processed for polyomavirus DNA and large T antigen (TAg) through real-time polymerase chain reaction (PCR) and immunohistochemistry (IHC). Results: BK polyomavirus and JC polyomavirus were detected in 21 cases (29.6%) and 10 cases (14.1%) with malignant tumors, respectively. The percentage of cases with double positive BK polyomavirus DNA and TAg was found to be high (62.20%). The specificity was high for both BK and JC viruses (98.48%). Conclusion: The study suggests that JC and BK polyomaviruses may play an important role in the urothelial tumor development.
