Site-specific bone marrow biopsies may miss focal disease, while FDG PET/CT detects metabolically active lesions, and the two approaches offer complementary prognostic value. <b>Materials and Methods:</b> This prospective study included 44 newly diagnosed multiple myeloma patients. The primary aim was to assess the correlation between biochemical and PET/CT responses at six months post-induction. A secondary objective was to evaluate the impact of PET/CT response on 12-month event-free survival (EFS). <b>Results:</b> The median age was 55.5 years. At baseline, more than 3 focal lesions and extramedullary disease (EMD) were observed in 61.4% and 34.1% of patients, respectively. After six months of induction therapy, 86.3% achieved at least a very good partial response (≥VGPR) biochemically, but 52.3% remained PET/CT-positive. Baseline >3 focal lesions and EMD significantly predicted persistent PET/CT positivity (p = 0.004). Notably, 50% of patients with ≥VGPR still showed PET/CT-positive findings. At 12 months, 75% of patients who experienced clinical events had been PET/CT-positive at six months, compared with 47.2% of those without events (p = 0.245). The 12-month event-free survival was lower in the PET/CT-positive group (73.9% vs. 90.4%, p = 0.182), though this difference was not statistically significant. <b>Conclusion:</b> 18-FDG PET/CT can detect residual disease not captured by biochemical markers, highlighting the value of combined assessment in multiple myeloma.

Early detection through effective screening methods is crucial for reducing morbidity and mortality. Opportunistic cervical cytology testing in outpatient settings plays an important role in the early identification of precancerous lesions. <b>Materials and Methods:</b> This cross-sectional study aimed to evaluate the effectiveness of liquid-based cytology (LBC) in detecting precancerous lesions and cervical cancer in a defined population. One hundred women aged between 25 and 75 years were screened using LBC.

Although standard guidelines exist globally, their direct application in Iran is not always possible due to differences in the types of common fungi and limited diagnostic and therapeutic facilities. To address this challenge, a national committee of experts in the field was formed to carefully review internationally recognized protocols published up to 2024 and solicit opinions from selected experts across the country to develop the first national guideline specifically for prophylaxis. To ensure methodological rigor, the Appraisal of Guidelines for Research and Evaluation II (AGREE II) framework and Grading of Recommendations Assessment, Development and Evaluation (GRADE) system were utilized. The resulting consensus established a localized risk-stratification model identifying acute myeloid leukemia (AML), myelodysplastic syndromes (MDS), and active graft-versus-host disease (GVHD) patients as high-risk, recommending posaconazole as the primary standard. Notably, the guideline advises against routine azole use in acute lymphoblastic leukemia (ALL) to prevent neurotoxicity. Furthermore, a resource-tiered framework was developed for centers with varying diagnostic capabilities. The result of this effort was to present a tiered and local model that provides a practical solution for both well-equipped and limited facilities.

This systematic review and meta-analysis evaluates the diagnostic performance and clinical utility of 3D CNNs across 22 studies, of which 11 were eligible for quantitative synthesis. Pooled sensitivity, specificity, and AUC were 0.72, 0.73, and 0.77, respectively, with a diagnostic odds ratio of 10.38, indicating favorable discriminative ability. Subgroup analyses demonstrated superior accuracy in lung cancer and CT-based models, with DenseNet and ResNet architectures outperforming traditional CNNs. Technical innovations-including multi-modal fusion, spatial context integration, and explainable AI techniques-enhance model robustness and clinician trust. However, substantial heterogeneity (I² > 95%) across studies, attributable to differences in imaging protocols, dataset quality, and model design, underscores the need for standardized methodologies. Persistent challenges include computational demands, annotation variability, and generalization limitations. Future directions should prioritize the integration of explainable AI, PACS-compatible user interfaces, and federated learning frameworks to bridge institutional gaps.

The RhD-negative phenotype arises through various molecular mechanisms in different populations, most commonly complete deletion of the <i>RHD</i> gene caused by unequal recombination between upstream and downstream Rhesus box sequences. Although this mechanism has been well documented in some populations, limited data are available from Iran, particularly its eastern regions. This study aimed to determine the molecular basis of the RhD-negative phenotype among blood donors in eastern Iran. <b>Materials and Methods:</b> In this cross-sectional study, a total of 16,190 blood donors referred to blood transfusion centers in South Khorasan Province, eastern Iran, over a one-year period were screened serologically for RhD status. Among them, 2,198 individuals were identified as RhD-negative, and 100 serologically confirmed RhD-negative donors were randomly selected for molecular evaluation. RhD typing was performed using standard serologic methods and verified by indirect antiglobulin testing. Molecular investigations included PCR-sequence-specific priming (PCR-SSP) targeting <i>RHD</i> exons 5, 7, and 10, real-time PCR for confirmation, and PCR-restriction fragment length polymorphism (PCR-RFLP) to detect the hybrid Rhesus box and determine <i>RHD</i> zygosity. <b>Results:</b> Among 16,190 blood donors screened during the study period, 2,198 (13.57%) were identified as RhD-negative.

PCR-RFLP analysis further confirmed that all donors were homozygous for the hybrid Rhesus box, with full concordance observed between exon-specific assays and hybrid Rhesus box genotyping. <b>Conclusion:</b> These findings indicate that the RhD-negative phenotype in eastern Iran is primarily due to homozygous <i>RHD</i> gene deletion mediated by the hybrid Rhesus box.
