Superior mesenteric artery syndrome (SMAS) is an uncommon condition which is difficult to diagnose due to non-specificity of symptoms. The most common causes of SMAS are severe weight loss secondary to severe medical conditions, surgical history, and cancer. A 31-year-old male with a history of ulcerative colitis status-post proctocolectomy with ileal pouch-anal anastomosis 10 years prior, presented with progressively worsening weight loss and abdominal pain. Radiographic imaging was consistent with SMAS, which was subsequently confirmed intraoperatively during an emergency surgery in which a Roux-En-Y gastrojejunostomy was performed. Clinicians should be aware that SMAS is a rare but possible complication of ileal pouch-anal anastomosis. Although rare, there should be a low threshold for this diagnosis when obstructive symptoms present.

AIM: To compare one step macular hole and cataract surgery with two step surgery in patients with macular hole and cataract.
●METHODS: ln a clinical trial conducted on patients suffering from cataract with macular holes inTabriz, the effects of simultaneous surgery of macular hole and cataract performed on these patients were studied. ln this study, 22 patients ( Group A ) were, first, undergone phacoemulsification and intraocular lens embedment, and one month later, 23-gauge pars plana vitrectomy together with the retinal internal limiting membrane ( lLM ) removal. Twenty - one patients ( Group B ) were undergone simultaneous phacoemulsification, intraocular lens embedment, 23-gauge pars plana vitrectomy, and the retinal lLM removal.
●RESULTS: Group A was comprised of 7 males and 15 females, and Group B of 9 males and 12 females ( P=0. 545) . The mean age of patients in Group A and B were 66.63±4. 75 and 67. 71±4. 99y, respectively (P=0. 472). Three months after surgeries were performed, the macular holes of 2 patients from Group A and 5 patients from Group B were open ( P = 0. 240 ). Uveitis was observed in 1 patient from Group A and 4 from Group B (P=0. 185). The increase of intraocular pressure (lOP) was merely observed in 2 patients from Group B ( P=0. 233 ) . Posterior capsule opacification ( PCO ) was observed, three months after surgeries, in 2 patients from Group A and 4 from Group B (P=0. 412).
● CONCLUSION: The results suggested that, no significant difference existed between patients from the two groups in terms of outcome and postoperative complications, although,Group B patients, the recipients of simultaneous surgeries, experienced more complications compared to their Group A counterparts.

BACKGROUND: Cell-free DNA (cfDNA) has the potential to serve as a non-invasive prognostic biomarker in some types of neoplasia. The investigation of plasma concentration of cfDNA may reveal its use as a valuable biomarker for risk stratification of diffuse large B-cell lymphoma (DLBCL). The present prognostic value of plasma cfDNA has not been widely confirmed in DLBCL subjects. Here, we evaluated cfDNA plasma concentration and assessed its potential prognostic value as an early DLBCL diagnostic tool. METHODS: cfDNA concentrations in plasma samples from 40 patients with DLBCL during diagnosis and of 38 normal controls were determined with quantitative polymerase chain reaction (qPCR) for the multi-locus L1PA2 gene. RESULTS: Statistically significant elevation in plasma cfDNA concentrations was observed in patients with DLBCL as compared to that in normal controls (P<0.05). A cutoff point of 2.071 ng/mL provided 82.5% sensitivity and 62.8% specificity and allowed successful discrimination of patients with DLBCL from normal controls (area under the curve=0.777; P=0.00003). Furthermore, patients with DLBCL showing higher concentrations of cfDNA had shorter overall survival (median, 9 mo; P=0.022) than those with lower cfDNA levels. In addition, elevated cfDNA concentration was significantly associated with age, B-symptoms, International Prognostic Index (IPI) score, and different stages of disease (all P<0.05). CONCLUSION: Quantification of cfDNA with qPCR at the time of diagnosis may allow identification of patients with high cfDNA concentration, which correlates with aggressive clinical outcomes and adverse prognosis.

Acute myeloid leukemia (AML) is a heterogeneous hematologic malignancy with an unfavorable outcome. The present research aimed to identify novel biological targets for AML diagnosis and treatment. In this study, we per‑ formed an in-silico method to identify antisense RNAs (AS-RNAs) and their related co-expression genes. GSE68172 was selected from the AML database of the Gene Expression Omnibus and compared using the GEO2R tool to find DEGs. Antisense RNAs were selected from all the genes that had significant expression and a survival plot was drawn for them in the GEPIA database, FOXD2-AS1 was chosen for further investigation based on predetermined criteria (logFC ≥|1| and P < 0.05) and its noteworthy association between elevated expression level and a marked reduction in the overall survival (OS) in patients diagnosed with AML. The GEPIA database was utilized to investigate FOXD2-AS1-related co-expression and similar genes. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis and gene ontology (GO) function analysis of the mentioned gene lists were performed using the DAVID database. The protein–protein interaction (PPI) network was then constructed using the STRING database.Hub genes were screened using Cytoscape software. Pearson correlation analysis was conducted using the GEPIA database to explore the relationship between FOXD2-AS1 and the hub genes. The transcription of the selected cod‑ ing and non-coding genes, including FOXD2-AS1, CDC45, CDC20, CDK1, and CCNB1, was validated in 150 samples, including 100 primary AML non-M3 blood samples and 50 granulocyte colony stimulating factor (G-CSF)-mobilized healthy donors, using quantitative Real-Time PCR (qRT-PCR). qRT-PCR results displayed significant upregulation of lnc-FOXD2-AS1, CDC45, and CDK1 in primary AML non-M3 blood samples compared to healthy blood samples (P = 0.0032, P = 0.0078, and P = 0.0117, respectively). The expression levels of CDC20 and CCNB1 were not statistically different between the two sets of samples (P = 0.8315 and P = 0.2788, respectively). We identified that AML patients with upregulation of FOXD2-AS1, CDK1, and CDC45 had shorter overall survival (OS) and Relapse-free survival (RFS) compared those with low expression of FOXD2-AS1, CDK1, and CDC45. Furthermore, the receiver operating charac‑ teristic (ROC) curve showed the potential biomarkers of lnc -FOXD2-AS1, CDC45, and CDK1 in primary AML non-M3 blood samples. This research proposed that the dysregulation of lnc-FOXD2-AS1, CDC45, and CDK1 can contribute to both disease state and diagnosis as well as treatment. The present study proposes the future evolution of the func‑ tional role of lnc-FOXD2-AS1, CDC45, and CDK1 in AML development.

The aim of this study is to assess the effects of different glucocorticoid administration protocols on biomechanical properties of the first lumbar vertebral body in rats. We divided 40 male rats into the following groups: control, dexamethasone (7 mg/week), dexamethasone (0.7 mg/week), methylprednisolone (7 mg/kg/week), methylprednisolone (5 mg/kg twice weekly), dexamethasone (7 mg/kg three times per week), dexamethasone (0.7 mg/kg three times per week, and low-level laser treated rats. Lumbar vertebrae in rats were exposed to the pulsed laser. We conducted a biomechanical test to examine the mechanical properties of vertebral body in rats' lumbar bone. Supraphysiologic glucocorticoid administration protocols did not impair the biomechanical properties of rats' vertebral bodies compared to control and laser-treated rats. Supraphysiologic glucocorticoid administration caused an anabolic effect on the vertebral bodies.
