    Abstract Abstract: A 17-year-old man presented with dull pain in the left upper abdomen for 1 month. Initial CT and gastroscopy revealed a mass in the gastric fundas, protruding into the lumen. Based on findings of a fine-needle biopsy, an inflammatory myofibroblastic tumor was suspected. Subsequent PET/CT showed increased FDG uptake in the gastric fundas as well as hepatogastric ligament, para-aortic region. Eventually, he underwent surgical resection, and histopathologic findings confirmed the diagnosis of splenosis.

    Abstract Abstract: A 60-year-old man with colonic diffuse large B-cell lymphoma was referred for FDG PET/CT for initial staging. He was suspected of enterovesical fistula. After oral administration, large amounts of contrast agents accumulated in the bowel lumen and leaked into the bladder through a well-marked fistulous tract. Corresponding to the fistula, a linear pattern of FDG uptake extended from the bladder into the colonic lumen, and the measured SUV max inside the lesion was as high as that of the urinary bladder. Cystography confirmed the presence of the enterovesical fistula.

    Abstract Gestational diabetes mellitus (GDM) is a common disease in pregnant women that threatens maternal and fetal health. Circular RNAs (circRNAs) have been considered potential diagnostic markers for GDM and affect trophoblast cell phenotypes. This study aimed to explore the effect of circSESN2 on high glucose (HG)-treated trophoblast cells. Peripheral blood and placental tissues were taken from patients with GDM, in which circSESN2 and IGF2BP2 levels were detected by quantitative reverse transcription polymerase chain reaction and/or western blot. HTR-8/SVneo cells were treated with 25 mM glucose and transduced with circSESN2 or IGF2BP2 knockdown vectors. HTR-8/SVneo cell viability was evaluated by MTT assay, cell migration by scratch test, and cell invasion by transwell assay, IL-1β, IL-6, TNF-α, malondialdehyde, and superoxide dismutase levels by ELISA or kits, and reactive oxygen species levels by DCFH-DA probes. The binding between circSESN2 and IGF2BP2 was verified by RNA pulldown and RIP assays. CircSESN2 and IGF2BP2 were overexpressed in GDM patients. Suppressing circSESN2 or IGF2BP2 increased HTR-8/SVneo cell invasion and migration, decreased cell apoptosis, and reduced pro-inflammatory cytokine release and oxidative stress injury. CircSESN2 bound IGF2BP2 and IGF2BP2 overexpression accelerated HG-induced HTR-8/SVneo cell damage despite circSESN2 knockdown. Collectively, circSESN2 exacerbated HG-induced trophoblast cell damage by binding IGF2BP2 and upregulating its protein expression.

    Abstract Purpose: To systematically determine the role of FDG PET/CT for the diagnosis of bone marrow involvement in mature T- and natural killer (NK)-cell lymphomas.
    Methods: The PubMed, Embase and Cochrane Library databases were searched to identify eligible studies. Data extraction and quality assessment were independently conducted. Then, pooled diagnostic performance with the 95 % confidence interval (CI) was calculated and further analyzed based on different interpretation criteria, tumor type and stage.
    Results: Fifteen studies were eventually included for quantitative analysis. Overall, the methodological quality of included studies was acceptable. For detecting bone marrow involvement, FDG PET/CT achieved a poor sensitivity of 0.62 (95 % CI, 0.48-0.71) and a reasonable specificity of 0.92 (95 % CI, 0.87-0.96). Similar performance was observed for the specific type of extranodal NK/T-cell lymphoma (ENKTCL). In early-stage patients revealed by PET/CT, extremely small proportion (2/777) showed positive bone marrow biopsy, especially for the specific type of ENKTCL, whereas in advanced-stage patients, the specificity of FDG PET/CT dropped to 0.77 (95 % CI, 0.72-0.82). Regarding the interpretation, both diffuse and focal increased uptake patterns as positivity may result in increased sensitivity but decreased specificity compared with focal pattern alone as positivity.
    Conclusions: FDG PET/CT demonstrated excellent negative predictive value for detecting marrow involvement in early-stage patients with mature T- and NK-cell lymphomas, especially the ENKTCL. Conversely, FDG PET/CT showed poor performance for the diagnosis of bone marrow involvement in advanced-stage patients.

    Abstract Large-scale association analyses using whole-genome sequence data have become feasible, but understanding the functional impacts of these associations remains challenging. Although many tools are available to predict the functional impacts of genetic variants, it is unclear which tool should be used in practice. This work provides a practical guide to assist in selecting appropriate tools for variant annotation. We conducted a MEDLINE search up to November 10, 2023, and included tools that are applicable to a broad range of phenotypes, can be used locally, and have been recently updated. Tools were categorized based on the types of variants they accept and the functional impacts they predict. Sequence Ontology terms were used for standardization. We identified 118 databases and software packages, encompassing 36 variant types and 161 functional impacts. Combining only three tools, namely SnpEff, FAVOR, and SparkINFERNO, allows predicting 99 (61%) distinct functional impacts. Thirty-seven tools predict 89 functional impacts that are not supported by any other tool, while 75 tools predict pathogenicity and can be used within the ACMG/AMP guidelines in a clinical context. We launched a website allowing researchers to select tools based on desired variants and impacts. In summary, more than 100 tools are already available to predict approximately 160 functional impacts. About 60% of the functional impacts can be predicted by the combination of three tools. Unexpectedly, recent tools do not predict more impacts than older ones. Future research should allow predicting the functionality of so far unsupported variant types, such as gene fusions.URL: https://cardio-care.shinyapps.io/VEP_Finder/ .Registration: OSF Registries on November 10, 2023, https://osf.io/s2gct .

    Abstract BACKGROUND Large cancer lesions are often challenging to treat with surgical intervention alone. Neoadjuvant chemotherapy is frequently used for FIGO stage IB3 and IIA2 cervical cancers to optimize the outcomes of radical surgeries. This study aimed to compare the effectiveness of neoadjuvant chemotherapy, followed by adjuvant chemotherapy and radiotherapy, if necessary, with the traditional approach of adjuvant chemotherapy and radiotherapy after radical hysterectomy in treatment-naïve patients with cervical cancer of specified stages. MATERIAL AND METHODS A total of 245 female patients were administered either 70 to 85 mg/m² cisplatin and 165 to 175 mg/m² paclitaxel every 21 days (2 cycles) prior to radical hysterectomy, followed by adjuvant chemotherapy and radiotherapy if needed (neoadjuvant therapy, NT cohort, n=105), or received adjuvant chemotherapy and radiotherapy after radical hysterectomy adjuvant therapy, AT cohort, n=140). RESULTS In the NT cohort, 76% of patients responded to neoadjuvant chemotherapy, while 24% did not. Adverse operative, intraoperative, and postoperative outcomes were significantly more common among the non-responders (P<0.05). After 5 years, 91% of responders and 72% of non-responders survived without recurrence (P=0.0372), and 3% of responders and 28% of non-responders had died (P=0.0005). CONCLUSIONS The resistance to neoadjuvant chemotherapy is a poor prognostic factor. Neoadjuvant chemotherapy followed by radical hysterectomy and adjuvant chemotherapy/radiotherapy appears to be advantageous for cervical cancer patients who respond well to neoadjuvant chemotherapy.

    Abstract The inhibition of checkpoint receptors (PD-1, PD-L1, and CTLA-4) with monoclonal antibodies has shown great benefit in clinical trials for treating cancer patients and has become a mainstay approach in modern cancer immunotherapy. However, only a subset of patients respond to checkpoint monoclonal antibody immunotherapy. Therefore, it is urgent to develop new therapeutic strategies against cancer. A novel B-cell peptide epitope PDL1 (programmed death ligand 1) cancer vaccine has been developed, with amino acids 130-147 linked to the MVF peptide ("promiscuous" T-cell measles virus fusion protein) via a GPSL linker. Preclinical testing has indicated that this PDL1 vaccine (PDL1-Vaxx) effectively stimulates highly immunogenic antibodies in animals. Animals immunized with PDL1-Vaxx show reduced tumor burden and extended survival rates in various animal cancer models. The mechanisms of action indicate that vaccine-elicited antibodies inhibit tumor cell proliferation, induce apoptosis, and block the PD-1/PD-L1 interaction. This manuscript introduces a magnetic bead-based assay that uses a dual-reporter flow analysis system to evaluate the PD-1/PD-L1 interaction and its blockade by the anti-PDL1 antibodies raised against the PDL1-Vaxx.
