Purpose: The association between the healing of an injured anterolateral ligament (ALL) and residual pivot-shift following anterior cruciate ligament (ACL) reconstructions is rarely reported. This study analyzed the relationship between unhealed ALL and residual pivot-shift after an ACL reconstruction. Materials and Methods: The inclusion criteria were patients who underwent autologous hamstring ACL reconstructions within 6 weeks after injury from January 2008 to March 2021. Preoperative ALL injuries and postoperative ALL healing were graded according to the magnetic resonance imaging classification, with postoperative magnetic resonance imaging performed 7.8 months after surgery on average. The patients were categorized based on postoperative ALL healing, and the clinical scores (Lysholm score and Tegner activity scale) and knee stability (Lachman test and pivot-shift test) were assessed at the 1-year postoperative follow-up. Results: One hundred and forty-five patients were enrolled in this study. One hundred and twenty-eight (88.3%) patients had a concomitant ALL injury. Among 86 patients with preoperative grade B, 16 (18.6%) patients showed grade 1 (good), and 70 (81.4%) showed grade 2 (partial) ALL postoperatively. Among the 42 patients with preoperative grade C (complete tear), 1 (2.4%) patient showed grade 1 (good), 21 (50.0%) showed grade 2 (partial), and 20 (47.6%) showed grade 3 (non-visualized) ALL. Preoperative grade C was significantly associated with a higher incidence of grade 3 (non-visualized) postoperatively than the other groups (p<0.001). Postoperatively, the Lachman test, KT-1000 (MEDmetric Corp.) arthrometer (side-to-side difference), Lysholm score, and Tegner activity scales did not show a significant difference among the intact, grade 1, grade 2, and grade 3 ALL groups. The pivot-shift test showed a significant difference between the ALL grades (p=0.001). Grade 3 ALL group showed a higher incidence of pivot-shift than the intact, grade 1, and grade 2 ALL groups. Conclusion Patients with preoperative grade C had a higher rate of grade 3 postoperatively compared to the other groups. In addition, the grade 3 group had a significantly higher incidence of a pivot-shift. Therefore, in cases of ACL injuries with concomitant complete ALL tears, ALL reconstruction should be considered during ACL reconstruction.

Conversion therapy is a treatment strategy that shifts from palliative systemic therapy to curative surgical treatment for primary and/or metastatic stage IV gastric cancer (GC).To address its clinical statements, the Korean Gastric Cancer Association aims to present a consensus on conversion therapy among experts attending KINGCA WEEK 2024. The KINGCA Scientific Committee and Development Working Group for Korean Practice Guidelines prepared preformulated topics and 9 clinical statements for conversion therapy.The Delphi method was applied to a panel of 17 experts for consensus and opinions. The final comments were announced after the statement presentation and discussed during the consensus meeting session of KINGCA WEEK 2024. Most experts agreed that conversion herapy provides a survival benefit for selected patients who respond to systemic therapy and undergo R0 resection (88.3%). Patients with limited metastases were considered good candidates (94.2%). The optimal timing was based on the response to systemic therapy (70.6%). The regimen was recommended to be individualized (100%) and the duration to be at least 6 months (88.3%). A minimally invasive approach (82.3%) and D2 lymph node dissection (82.4%) were considered for surgery. However, resection for metastases with a complete clinical response after systemic therapy was not advocated (41.2%). All experts agreed on the need for large-scale randomized-controlled trials for further evidence (100%).Recent advancements in treatment may facilitate radical surgery for patients with stage IV GC. Further evidence is warranted to establish the safety and efficacy of conversion therapy.

This study examined the colostrum nutritive composition, immunoglobulin (Ig), and microbial community in Holstein and Jersey dairy cows according to the time after calving. The experiment used seven Holstein and three Jersey dairy cows. Colostrum was collected immediately after calf calving, 12, and 24 hours, and stored at −80°C until analysis. An analysis of the nutritive composition in colostrum was performed using LactoScop. The immune indicators were analyzed using an ELISA Kit, and the microbial community was assessed using a Macrogen Inc. The protein level was high in all colostrum samples from Holstein dairy cows compared with Jersey dairy cows, but there was no significant difference according to the time after calving. Immune index analysis revealed high IgG and IgA concentrations in the colostrum of Holstein cows immediately after calving and 12 and 24 hours after calving, but the differences were not significant. The microbial community at the genus level revealed Staphylococcus to be predominant at a high rate in the colostrum of Holstein dairy cows and Enterococcus in Jersey dairy cows 12 hours after calving. Pseudomonas was predominant at a high rate in the colostrum of Jersey lactating cows immediately and 12 hours after calving. Chryseobacterium was predominant at a high rate in Holstein dairy cows 12 and 24 hours after calving. In conclusion, these results are expected to be used as research data on the correlation between quality, immunity, and microbial community in the colostrum. In the future, beneficial microorganisms in the colostrum of domestic dairy cows can be used to improve the growth and immunity of Holstein and Jersey calves and assist in research related to postbiotics industrialization.
