Abstract
Background: Diabetes Mellitus (DM) is a metabolic disorder whose pathophysiology has been linked to various genetic and environmental factors. The main mechanism of the development of complications has been implicated as inflammation-mediated. Various blood cell parameters are being used as early indicators of inflammation-mediated endothelial dysfunction; thereby predicting the severity or prognosis of DM. In this study, we aimed to evaluate the role of platelet-to-lymphocyte ratio (PLR) in predicting glycemic control in patients with DM.
Methods: This is a retrospective, hospital-based study conducted from August 2023 to December 2023. A total of 134 patients were included in the study. The hematological and biochemical reports of the study population were retrieved, and the data obtained was analyzed using SPSS software version 16.0.
Results: In this study, it has been found that PLR is significantly increased in patients suffering from DM with poor glycemic control compared to those patients with good glycemic control (P<0.001). In concordance with other studies, a positive association was observed between PLR and disease severity.
Conclusion: Based on the findings of the study, PLR may be used as a predictive marker in assessing the severity and prognosis of DM; however, the exact cut-off value is yet to be determined.

Abstract
Background: The reference method for antifungal susceptibility testing is broth microdilution according to Clinical and Laboratory Standard Institute (CLSI) guidelines. However, the fully automated system, Vitek 2C system may reduce the workload and observer bias associated with manual broth microdilution. This study aimed to compare the results of YS08 card with the results of the broth microdilution (BMD) method.
Methods: A total of 50 clinical Candida isolates were included in the study. The susceptibility testing was done by Vitek 2C using the YS08 card. Broth microdilution was done according to CLSI guidelines M27M44S-Ed3.
Results: For C. albicans, the categorical agreement was 85.8%, 71.5%, 85.8%, and 100% for fluconazole, voriconazole, caspofungin, and micafungin, respectively. The minor errors (MiE) of 14.2% for fluconazole and caspofungin, 28.5% for voriconazole, were detected in C. albicans. In C. glabrata, the categorical agreement (CA) was 100% for micafungin, voriconazole, but 63.7% for caspofungin. An MiE of 36.3% was detected for caspofungin. C. parapsilosis showed a 100% CA for fluconazole, caspofungin, and micafungin, and 85.8% for voriconazole. There were 14.2% of MiEs for voriconazole. In C. tropicalis, 100 % CA was observed for fluconazole, micafungin, and caspofungin, and 88.9% for voriconazole. Moreover, 11.1% (1/9) of MiEs was observed for voriconazole. In C. auris, there was a 100% CA for caspofungin and micafungin, 77.8% for fluconazole, and 66.7% for amphotericin B. There was a major error of 22.2% for fluconazole and 33.3% for amphotericin B.
Conclusion: The majority of Vitek 2C showed comparable results with the broth microdilution (BMD) method. Only minor errors (MiEs) were observed in the tested Candida species.

Abstract
Background: Running and starvation can have a positive effect on the reticulophagy of the liver tissue. The purpose of this research was to investigate the effect of running and starvation interventions on the atherogenic index and Xbp1 gene change in the liver endoplasmic reticulum of non-alcoholic fatty liver rats (NAFLD).
Methods: Thirty obese male Wistar rats aged 18-20 weeks with an average body weight of 348 ± 25.53 grams, after one week of familiarization with the laboratory environment, were randomly divided into six groups (n=5 per group): 1) starvation, 2) three days of training, 3) five days of training, 4) three days of training plus starvation, 5) five days of training plus starvation, and 6) the control group. All fatty liver animal models had free access to water and standard food pellets (10 gr per 100 g of mouse body weight). The statistical test of one-way analysis of variance was used at a significance level of less than 0.05, and the LSD post-hoc test was used to compare research groups.
Results: According to the experimental results and statistical analyses (One-way analysis of variance), a significant decrease was noticed in the ratio of lipoproteins (VLDL/HDL and LDL/HDL) in all experimental groups compared to the control group. Also, a significant decrease was observed in the expression of XBP1 and CHOP genes in animals doing 3 and 5 days of exercise alone or along with starvation.
Conclusion: Regular exercise for 3 and 5 days per week with starvation can possibly reduce the activity of the genes involved in endoplasmic reticulum stress in NAFLD patients.

Abstract
Background and objectives: Urinary tract infection (UTI) caused by Uropathogenic Escherichia coli (UPEC) is a worldwide health problem. Virulence factors (VFs) expressed by UPEC strains promote the pathogenicity of bacteria in the urinary tract. Treatment of the infection is often difficult due to the high antimicrobial resistance of E. coli. This study aimed to determine VFs and the antibiotic susceptibility pattern of isolated UPEC strains in the north of Iran.
Methods: 105 urine samples were collected from females with UTIs, in north of Iran, Rasht. The samples were cultured on EMB agar and MacConkey agar. The plates were incubated at 37°C for 24 h and the pure isolates were identified using Gram-stains and standard biochemical tests. The presence of six VF genes including papC, sfa/foc, fimH, afa, ibeA and neuC were identified by polymerase chain reaction (PCR) in UPEC strains and verified by direct sequencing. Antibiotic susceptibility test (AST) was performed by disk diffusion method based on the Clinical and Laboratory Standards Institute (CLSI) guidelines.
Results: 65.71% isolates were identified as E. coli. The most frequent virulence gene was fimH (100%) and the least one was afa (1.44%). The highest and the lowest antibiotic resistance rates were observed against Cephazolin (66.66%), and Gentamicin (24.63%), respectively. Indeed, the prevalence of multiple drug resistance (MDR) was determined as 73.91%.
Conclusion: Our study highlighted the importance of local monitoring in UPEC isolates due to the high genetic mutation capacity of the pathogen, environmental and patient properties to recommend the best strategies against UTIs.

Abstract
Background and objectives: Enterobius vermicularis is the most important intestinal parasite in children worldwide. When this parasite migrates unexpectedly, the larvae move out of the intestine and enter organs such as the appendix and can cause health risks.
Case report: An 8-year-old boy was admitted to the oncology clinic of Tabriz Children’s Hospital complaining of fever of 39-40°C with abdominal pain, cramps, loss of appetite, weakness and fatigue associated with cervical lymphadenopathy, hepatomegaly, axillary mass, abdominal upper thigh, maculopapular rashes and tiny petechiae on the chest and abdomen.
Results: On CT examination of the chest, moderate mediastinal and mesenteric lymphadenopathy was noted. The patient was hospitalized with a definitive diagnosis of acute lymphoblastic leukemia (ALL). On the seventh day of hospitalization, the patient developed additive colic pain (contraction and cramping) around the umbilicus and concomitantly developed pain downward and rightward into the abdomen. Based on the clinical findings, the patient was thought to have acute appendicitis. Pathological examinations showed that E. vermicularis was the cause of the appendicitis.
Conclusion: The results of this study indicate that this parasite may be associated with inflammation of the appendix in patients with acute lymphoblastic leukemia. A screening program is still required in patients with immunodeficiency or those taking immunosuppressive drugs.
