Objective:
Neuroinflammation’s role is increasingly emphasized in the pathology of major depressive disorder (MDD), and its close association with the risk of suicide is being reported. The Forkhead Box O1 (FoxO1) gene is known to play a role in regulating mood and emotion and is associated with susceptibility to suicidality in relation to environmental stress. This research aims to explore the relationship between FoxO1 and the risk of suicide in individuals with MDD.
Methods:
We enrolled 127 healthy controls (HC) and 231 patients diagnosed with MDD, including 119 individuals with high suicide risk (HSR). All participants underwent the Hamilton Rating Scale for Depression Assessment and magnetic resonance imaging. Cortical thickness and white matter integrity were evaluated.
Results:
In the HSR group, cortical thinning was observed in the left triangular part of the inferior frontal gyrus and right transverse frontopolar gyrus compared to HC. Additionally, fractional anisotropy (FA) values were decreased in the left posterior thalamic radiation, sagittal stratum, and uncinate fasciculus. Although no differences were observed based on allele variations for the two FoxO1 single nucleotide polymorphisms (SNPs), those with the minor allele of FoxO1 rs34733279, especially in the HSR group, displayed increased cortical thinning and reduced FA values in the left cingulum.
Conclusion
Our study reveals close association between the minor allele of the FoxO1 gene rs34733279 and suicide risk in the left cingulum highlights the potential key role of the FoxO1 gene rs34733279 in the context of suicidal vulnerability. Further investigations are warranted to elucidate the underlying biological mechanisms.

Background/Aims:
The prognostic significance of 18F-fluorodeoxyglucose (FDG)-positron emission tomography-computed tomography (PET/CT) in peripheral T-cell lymphomas (PTCLs) are controversial. We explored the prognostic impact of sequential 18F-FDG PET/CT during frontline chemotherapy of patients with PTCLs.
Methods:
In total, 143 patients with newly diagnosed PTCLs were included. Sequential 18F-FDG PET/CTs were performed at the time of diagnosis, during chemotherapy, and at the end of chemotherapy. The baseline total metabolic tumor volume (TMTV) was calculated using the the standard uptake value with a threshold method of 2.5.
Results:
A baseline TMTV of 457.0 cm3 was used to categorize patients into high and low TMTV groups. Patients with a requirehigh TMTV had shorter progression-free survival (PFS) and overall survival (OS) than those with a low TMTV (PFS, 9.8 vs. 26.5 mo, p = 0.043; OS, 18.9 vs. 71.2 mo, p = 0.004). The interim 18F-FDG PET/CT response score was recorded as 1, 2–3, and 4–5 according to the Deauville criteria. The PFS and OS showed significant differences according to the interim 18F-FDG PET/CT response score (PFS, 120.7 vs. 34.1 vs. 5.1 mo, p < 0.001; OS, not reached vs. 61.1 mo vs. 12.1 mo, p < 0.001).
Conclusions
The interim PET/CT response based on visual assessment predicts disease progression and survival outcome in PTCLs. A high baseline TMTV is associated with a poor response to anthracycline-based chemotherapy in PTCLs. However, TMTV was not an independent predictor for PFS in the multivariate analysis.

Mucinous borderline tumors (MBT) of the ovary with mild to moderately atypical epithelial cells that produce mucin rarely recur and very rarely become malignant after surgery. Due to their low malignant potential and large tumor size, most cases are diagnosed in stage I and have a good prognosis. The authors reported a case of MBT, which had been left untreated after diagnosis, progressed to stage IV, and caused massive pleural effusion (>3,000 mL) resulting in death. Grossly, severe abdominal swelling, a huge multiloculated cystic mass in the left ovary, and a metastatic mucinous mass in the pleura and peritoneum were observed. Histological findings include gastrointestinal type epithelial cells with mucin secretion, degenerative and autolytic nuclei, and occasional infiltration of inflammatory cells. Because sufficient sections cannot be made according to the clinical pathology criteria in forensic autopsy, efficient decisions are required during autopsy for diagnosis.

Background and Objectives:
The standard surgical procedure for primary hyperparathyroidism is the bilateral exploration. However, the unilateral exploration and direct focused parathyroidectomy have been performed to reduce surgical morbidity. The purpose of this study was to report the surgical outcomes and efficacy of the bilateral exploration, unilateral exploration, and direct focused approaches for primary hyperparathyroidism.Subjects and Method We retrospectively analyzed the surgical outcomes of 87 patients with primary hyperparathyroidism from January 2007 to December 2017. We compared the operative time, complication and recurrence rate between the three operative methods.
Results:
The most common histopathology was parathyroid adenoma, which was found in 73 cases (83.9%), followed by hyperplasia. In terms of complications, there were two cases of transient vocal cord palsy, one case of hematoma, one case of hypocalcemia and one case of hungry bone syndrome. Recurrence occurred in two (2.3%) out of 87 cases. There was no significant difference in the recurrence rate between the three surgical approaches.
Conclusion
The success rate of surgery for primary hyperparathyroidism is high. Direct focused parathyroidectomy may be a good option for parathyroid adenoma if the localization tests localize the lesion. The bilateral exploration is effective for parathyroid hyperplasia.
10.Recent Progress in the Molecular Imaging of Tumor-Treating Bacteria

Bacterial cancer therapy (BCT) approaches have been extensively investigated because bacteria can show unique features of strong tropism for cancer, proliferation inside tumors, and antitumor immunity, while bacteria are also possible agents for drug delivery. Despite the rapidly increasing number of preclinical studies using BCT to overcome the limitations of conventional cancer treatments, very few BCT studies have advanced to clinical trials. In patients undergoing BCT, the precise localization and quantification of bacterial density in different body locations is important; however, most clinical trials have used subjective clinical signs and invasive sampling to confirm bacterial colonization. There is therefore a need to improve the visualization of bacterial densities using noninvasive and repetitive in vivo imaging techniques that can facilitate the clinical translation of BCT.In vivo optical imaging techniques using bioluminescence and fluorescence, which are extensively employed to image the therapeutic process of BCT in small animal research, are hard to apply to the human body because of their low penetrative power. Thus, new imaging techniques need to be developed for clinical trials. In this review, we provide an overview of the various in vivo bacteria-specific imaging techniques available for visualizing tumor-treating bacteria in BCT studies.
