Purpose:
Type 4 gastric cancer (GC) has a very poor prognosis even after curative resection, and the survival benefit of splenectomy for splenic hilar lymph node (LN; #10) dissection in type 4 GC remains equivocal. This study aimed to clarify the clinical significance of splenectomy for #10 dissection in patients with type 4 GC.
Materials and Methods:
The data of a total of 56 patients with type 4 GC who underwent total gastrectomy with splenectomy were retrospectively analyzed. Postoperative morbidity, state of LN metastasis, survival outcomes, and therapeutic value index (TVI) of each LN station were evaluated. TVI was calculated by multiplying the incidence of LN metastasis at each nodal station and the 5-year overall survival (OS) of patients who had metastasis to each node.
Results:
Overall, the postoperative morbidity rate was 28.6%, and the incidence of #10 metastasis in the patients was 28.6%. The 5-year OS rate for all patients was 29.9%, and most patients developed peritoneal recurrence. Moreover, the 5-year OS rates with and without #10 metastasis were 6.7% and 39.1% (median survival time, 20.4 vs. 46.0 months; P=0.006). The TVI of #10 was as low as 1.92.
Conclusions
The clinical significance of splenectomy in the dissection of #10 for type 4 GC is limited and splenectomy for splenic hilar dissection alone should be omitted.

Background: Unstable sternal fixation following sternotomy is one of the risk factors that affects postoperative outcomes in cardio-thoracic surgery and is associated with increased risk of infection, bleeding and delayed rehabilitation due to pain associated with sternal movement. Sternal plate systems, which help stabilize fixation, has been limited in use due to patients' comorbidities, such as diabetes mellitus (DM) and obesity. The conventional wire sternal-fixation procedure, which depend on years of physician' experience, raise concerns such as unstable sternal fixation due to uncompleted wire twisting. Therefore, a novel sternal-fixation procedure using both titanium cable and a PLA mesh plate was investigated as a potential improvement for sternal closure. We compared the ability of this new sternum fixation procedure (group N) against the conventional sternal fixation procedure using only a wire (group O) to achieve more stable postoperative sternal fixation. Methods and Results: Among adult open-heart surgeries performed between August 2020 and April 2023, 155 patients who underwent postoperative CT were included, with group N being the combined group and group O being the group using conventional metal wires: group N (86 patients: M 65, F 21) and group O (69 patients: M 50, F 19). Preoperative factors included age at surgery (group N: group O)=68.4±10.6 : 69.6±11.5 years (p=0.25)), BMI (group N: group O=23.0±3.7 : 24.1±7.7 (p=0.16)) and HbA1c (group N: group O=6.3±1.1 : 8.0±10.3% (p=0.10), and no factors were significantly different between the two groups. The CT analysis at the point of hospital discharge after surgery measured postoperative sternal deviation in the third rib position. Transverse displacement was significantly reduced (group N: group O=0.22±0.73: 0.83±1.08 mm (p=0.005)), and longitudinal displacement also showed an improvement but the difference was not statistically significant (group N: group O=0.53±0.86: 0.72±1.14 mm (p=0.13). Conclusion: A novel sternum closing technique using a tension-anchored titanium cable and a PLA mesh plate demonstrated improved postoperative sternal fixation in a controlled study with 155 patients. This new procedure also enables standardized stable sternal closure with a constant force without relying on conventional empirical sensation and without suppressing sternal cutting, thus contributing to the improvement of postoperative quality of life and prevention of complications.

BACKGROUND:
Epidemiological evidence for the relationship between education and income and carotid intima-media thickness (CIMT) has been limited and inconsistent. The present cross-sectional study investigated this issue using baseline data from the Aidai Cohort Study.
METHODS:
Study subjects were 2012 Japanese men and women aged 34-88 years. Right and left CIMT were measured at the common carotid artery using an automated carotid ultrasonography device. Maximum CIMT was defined as the largest CIMT value in either the left or right common carotid artery. Carotid wall thickening was defined as a maximum CIMT value > 1.0 mm.
RESULTS:
The prevalence of carotid wall thickening was 13.0%. In participants under 60 years of age (n = 703) and in those aged 60 to 69 years (n = 837), neither education nor household income was associated with carotid wall thickening or with maximum CIMT. Among those aged 70 years or older (n = 472), however, higher educational level, but not household income, was independently related to a lower prevalence of carotid wall thickening: the multivariate-adjusted odds ratio for high vs. low educational level was 0.43 (95% confidence interval 0.21-0.83, p for trend = 0.01). A significant inverse association was observed between education, but not household income, and maximum CIMT (p for trend = 0.006).
CONCLUSIONS
Higher educational level may be associated with a lower prevalence of carotid wall thickening and a decrease in maximum CIMT only in participants aged 70 years or older.
