Adenomyosis is a challenging clinical condition that is commonly being diagnosed in women of reproductive age. To date, many aspects of the disease have not been fully understood, making management increasingly difficult. Over time, minimally invasive diagnostic and treatment methods have developed as more women desire uterine preservation for future fertility or to avoid major surgery. Several uterine-sparing treatment options are now available, including medication, hysteroscopic resection or ablation, conservative surgical methods, and high-intensity focused ultrasound each with its own risks and benefits. Uterine artery embolization is an established treatment option for uterine fibroids and has recently gained ground as a safe and cost-effective method for treatment of uterine adenomyosis with promising results. In this review, we discuss current trends in the management of uterine adenomyosis with a special focus on uterine artery embolization as an alternative to hysterectomy.

Background
Posterior reversible encephalopathy syndrome (PRES) is a neurotoxic condition associated with a distinctive brain imaging pattern which typically occur in some complex clinical conditions. However, the leading offender to this condition remains not clear.
Case presentation
We report a 6-year-old female with
β
-thalassemia major presenting with generalized tonic–clonic convulsions, repeated attacks of projectile vomiting, blurred vision, and altered conscious level after blood transfusion. The brain magnetic resonance imaging (MRI) FLAIR sequence revealed bilateral and symmetrical subcortical edema displaying high signal intensity. Follow-up MRI 1 month later showed complete resolution of the previously identified findings. The clinical presentation along with neuroimaging pattern as well as the reversible course indicated PRES as the most suitable diagnosis. Although PRES has been previously described in different clinical settings, this is a rare case of PRES recognized after blood transfusion in a child with
β
-thalassemia major.
Conclusion
Acute neurological symptoms in children with thalassemia should raise high suspicion for PRES, especially after blood transfusion.

Gynecology Imaging Reporting and Data System (GI-RADS): diagnostic performance and inter-reviewer agreement
2019
ObjectiveTo evaluate diagnostic performance and inter-reviewer agreement (IRA) of the Gynecologic Imaging Reporting and Data System (GI-RADS) for diagnosis of adnexal masses (AMs) by pelvic ultrasound (US).Patients and methodsA prospective multicenter study included 308 women (mean age, 41 ± 12.5 years; range, 15–73 years) with 325 AMs detected by US. All US examinations were analyzed, and AMs were categorized into five categories according to the GI-RADS classification. We used histopathology and US follow-up as the reference standards for calculating diagnostic performance of GI-RADS for detecting malignant AMs. The Fleiss kappa (κ) tests were applied to evaluate the IRA of GI-RADS scoring results for predicting malignant AMs.ResultsA total of 325 AMs were evaluated: 127 (39.1%) were malignant and 198 (60.9%) were benign. Of 95 AMs categorized as GI-RADS 2 (GR2), none was malignant; of 94 AMs categorized as GR3, three were malignant; of 13 AMs categorized as GR4, six were malignant; and of 123 AMs categorized as GR5, 118 were malignant. On a lesion-based analysis, the GI-RADS had a sensitivity, a specificity, and an accuracy of 92.9%, 97.5%, and 95.7%, respectively, when regarding only those AMs classified as GR5 for predicting malignancy. Considering combined GR4 and GR5 as a predictor for malignancy, the sensitivity, specificity, and accuracy of GI-RADS were 97.6%, 93.9%, and 95.4%, respectively. The IRA of the GI-RADS category was very good (κ = 0.896). The best cutoff value for predicting malignant AMs was >GR3.ConclusionsThe GI-RADS is very valuable for improving US structural reports.Key Points• There is still a lack of a standard in the assessment of AMs.• GI-RADS is very valuable for improving US structural reports of AMs.• GI-RADS criteria are easy and work at least as well as IOTA.

Purpose The aim of our study is to provide insights derived from experience at multiple centers regarding the outcomes of mechanical thrombectomy (MT) for large vessel occlusion (LVO) in COVID-19 patients and compare them with those in non-COVID-19 patients during the coronavirus disease (COVID-19) pandemic. Results COVID-19 positive patients were younger than COVID-19 negative patients (62.1 ± 2.69 versus 69.5 ± 2.2, P < 0.001). There was a significant difference between COVID-19 and non-COVID-19 groups in the median D-dimer levels (6 vs. 4.5; P < 0.001), median ESR levels (63 vs. 38; P < 0.001) and median CRP levels (110 vs. 48.5; P < 0.001), respectively. Median time from stroke symptoms onset to hospital admission was significantly higher among COVID-19 positive patients (366 vs. 155 min; P < 0.001). COVID-19 positive patients with LVO presented with a higher median NIH Stroke Scale score at presentation (16 versus 8, P < 0.001) and lower median Alberta Stroke Program Early CT Score (ASPECTS) on admission (6 versus 8, P 0.05). Conclusion Mechanical thrombectomy has effectively managed patients with LVO stroke. LVO stroke in COVID-19 patients occur at a young age, and have multi-territory vascular involvement. Poor functional outcomes post thrombectomy in COVID-19 patients, irrespective of timely, successful angiographic recanalization.

Validating Brain Tumor Reporting and Data System (BT-RADS) as a Diagnostic Tool for Glioma Follow-Up after Surgery
2024
Gliomas are a type of brain tumor that requires accurate monitoring for progression following surgery. The Brain Tumor Reporting and Data System (BT-RADS) has emerged as a potential tool for improving diagnostic accuracy and reducing the need for repeated operations. This prospective multicenter study aimed to evaluate the diagnostic accuracy and reliability of BT-RADS in predicting tumor progression (TP) in postoperative glioma patients and evaluate its acceptance in clinical practice. The study enrolled patients with a history of partial or complete resection of high-grade glioma. All patients underwent two consecutive follow-up brain MRI examinations. Five neuroradiologists independently evaluated the MRI examinations using the BT-RADS. The diagnostic accuracy of the BT-RADS for predicting TP was calculated using histopathology after reoperation and clinical and imaging follow-up as reference standards. Reliability based on inter-reader agreement (IRA) was assessed using kappa statistics. Reader acceptance was evaluated using a short survey. The final analysis included 73 patients (male, 67.1%; female, 32.9%; mean age, 43.2 ± 12.9 years; age range, 31–67 years); 47.9% showed TP, and 52.1% showed no TP. According to readers, TP was observed in 25–41.7% of BT-3a, 61.5–88.9% of BT-3b, 75–90.9% of BT-3c, and 91.7–100% of BT-RADS-4. Considering >BT-RADS-3a as a cutoff value for TP, the sensitivity, specificity, and accuracy of the BT-RADS were 68.6–85.7%, 84.2–92.1%, and 78.1–86.3%, respectively, according to the reader. The overall IRA was good (κ = 0.75) for the final BT-RADS classification and very good for detecting new lesions (κ = 0.89). The readers completely agreed with the statement “the application of the BT-RADS should be encouraged” (score = 25). The BT-RADS has good diagnostic accuracy and reliability for predicting TP in postoperative glioma patients. However, BT-RADS 3 needs further improvements to increase its diagnostic accuracy.

Objective
To determine prognostic value of bone marrow retention index (RI-bm) and bone marrow-to-liver ratio (BLR) measured on baseline dual-phase
18
F-FDG PET/CT in a series of newly diagnosed patients with diffuse large B-cell lymphoma (DLBCL) treated homogeneously with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy.
Patients and methods
This prospective study enrolled 135 patients with newly diagnosed DLBCL. All patients underwent dual-phase
18
F-FDG PET/CT. The following PET parameters were calculated for both tumor and bone marrow: maximum standardized uptake value (SUVmax) at both time points (SUVmax early and SUVmax delayed), SUVmax increment (SUVinc), RI, and BLR. Patients were treated with R-CHOP regimen and response at end of treatment was assessed.
Results
The final analysis included 98 patients with complete remission. At a median follow-up of 22 months, 57 patients showed no relapse, 74 survived, and 24 died. The 2-year relapse-free survival (RFS) values for patients with higher and lower RI-bm were 20% and 65.1%, respectively (p < 0.001), and for patients with higher and lower BLR were 30.2% and 69.6%, respectively (
p
< 0.001). The 2-year overall survival (OS) values for patients with higher and lower RI-bm were 60% and 76.3%, respectively (
p
= 0.023), and for patients with higher and lower BLR were 57.3% and 78.6%, respectively (p = 0.035). Univariate analysis revealed that RI-bm and BLR were independent significant prognostic factors for both RFS and OS (hazard ratio [HR] = 4.02,
p
< 0.001, and HR = 3.23,
p
< 0.001, respectively) and (HR = 2.83,
p
= 0.030 and HR = 2.38,
p
= 0.041, respectively).
Conclusion
Baseline RI-bm and BLR were strong independent prognostic factors in DLBCL patients.
Clinical relevance statement
Bone marrow retention index (RI-bm) and bone marrow-to-liver ratio (BLR) could represent suitable and noninvasive positron emission tomography/computed tomography (PET/CT) parameters for predicting pretreatment risk in patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL) who were treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy.
Key Points
•
Bone marrow retention index (RI-bm) and bone marrow-to-liver ratio (BLR) are powerful prognostic variables in diffuse large B-cell lymphoma (DLBCL) patients
.
•
High BLR and RI-bm are significantly associated with poor overall survival (OS) and relapse-free survival (RFS)
.
•
RI-bm and BLR represent suitable and noninvasive risk indicators in DLBCL patients

The spread of breast cancer has become one of the health challenges in human societies. Breast cancer is the most common type of malignancy in women, and one of the three most common cancers worldwide, along with lung and colon cancer. Nowadays, breast cancer is the second cause of death after cardiovascular diseases. In general, about one out of eight women (about 12%) suffer from this disease during their life in the USA and European countries. If breast cancer is detected at an early stage, its survival rate will be very high. Several methods have been introduced to diagnose breast cancer with their clinical advantages and disadvantagesRecently, other new modalities like positron emission tomography, 99mTc-sestamibi scintimammography, and electrical impedance tomography (EIT) are also being offered. However, there is still controversy over the most appropriate use of these new modalities. Based on the literature, this review evaluates the role of various modalities used in the screening and diagnosis of breast cancer.

Inclusion of microbial fermented soybean meal in broiler feed has induced advantageous outcomes for their performance and gastrointestinal health via exhibiting probiotic effects. In this study, soybean meal (SBM) was subjected to double-stage microbial fermentation utilizing functional metabolites of fungi and bacteria. In broiler diet, DFSBM replaced SBM by 0, 25, 50 and 100%. DFSBM was reported to have higher protein content and total essential, nonessential and free amino acids (increased by 3.67%, 12.81%, 10.10% and 5.88-fold, respectively, compared to SBM). Notably, phytase activity and lactic acid bacteria increased, while fiber, lipid and trypsin inhibitor contents were decreased by 14.05%, 38.24% and 72.80%, respectively, in a diet containing 100% DFSBM, compared to SBM. Improved growth performance and apparent nutrient digestibility, including phosphorus and calcium, and pancreatic digestive enzyme activities were observed in groups fed higher DFSBM levels. In addition, higher inclusion levels of DFSBM increased blood immune response (IgG, IgM, nitric oxide and lysozyme levels) and liver antioxidant status. Jejunal amino acids- and peptide transporter-encoding genes (LAT1, CAT-1, CAT-2, PepT-1 and PepT-2) were upregulated with increasing levels of DFSBM in the ration. Breast muscle crude protein, calcium and phosphorus retention were increased, especially at higher inclusion levels of DFSBM. Coliform bacteria load was significantly reduced, while lactic acid bacteria count in broiler intestines was increased with higher dietary levels of DFSBM. In conclusion, replacement of SBM with DFSBM positively impacted broiler chicken feed utilization and boosted chickens’ amino acid transportation, in addition to improving the nutritional value of their breast meat.

Background
As the global prevalence of diabetes mellitus increases, the incidence of non-healing wounds in diabetic patients is expected to rise significantly, according to the International Diabetes Federation (IDF), around 537 million adults currently suffer from diabetes mellitus worldwide and 20% to 30% of individuals with diabetes are hospitalized due to diabetic foot ulcers. Conventional treatments such as traditional dressings often fall short in ensuring satisfactory wound healing, this Meta-analysis investigates the therapeutic potential of Adipose-derived Stem Cells (ADSCs) as a promising strategy for addressing this challenge.
Aims
To Assess the Therapeutic Potential of Adipose-Derived Stem Cells for Managing Diabetic Foot Ulcers compared to conventional lines of treatments.
Methods
The PubMed, SCOPUS, Web of Science Core Collection, Cochrane Library, and ClinicalTrials.gov. databases were searched from January 2000 and December 2023, articles were primarily evaluated regarding their titles and abstracts, then full-text screening was assessed against the inclusion and exclusion criteria by utilizing Rayyan software. The Cochrane risk of bias (RoB 2) assessment tool was used to identify the risk of bias in our included studies. A statistical analysis was performed using Review Manager (RevMan) Version 5 software. Dichotomous data was subjected to risk ratio analysis, while continuous data underwent Mean Difference (MD) evaluation, all was reported with 95% confidence intervals, P value is considered statistically significant if less than 0.05.
Results
Regarding the total healing state, five studies reported that more participants healed completely at the end of the follow-up period in the ADSCs group (Risk ratio = 1.56, 95% CI [1.32, 1.86], P < 0.00001), for the healing rate the overall effect estimate favors the ADSCs group (pooled effect estimate = 1.84, 95% CI [1.51, 2.89], P < 0.00001), and regarding the healing time the pooled mean difference of the studies demonstrated that the ADSCs group required fewer days to heal than the standard care group. (pooled mean difference = −19.33, 95% CI [−37.36, −1.29], P = 0.04).
Conclusion
ADSCs provide favorable healing results and safety compared to standard care for diabetic foot ulcers.
