Streptococcus suis, a zoonotic bacterial pathogen, has negative economic impacts on both intensive swine production and human health worldwide. Whole-genome sequencing and comparative genomic analysis have been widely used for comprehensive classification and investigation of the genetic basis of several S. suis strains obtained from distinct hosts in different geographic areas, revealing great genetic diversity of this zoonotic pathogen. In this study, whole-genome sequences of antibiotic-resistant S. LGK-974 inhibitor suis strains isolated from human patients (2 strains), diseased pigs (4 strains), and asymptomatic pigs (3 strains) in Thailand were compared with known genomes of 1186 S. suis strains. Single-nucleotide polymorphism-based phylogenetic analysis indicated that the Thai-isolated S. suis strains have close genetic relatedness to S. suis strains isolated from Canada, China, Denmark, Netherlands, United Kingdom, and United States of America. The genome analysis revealed genes conferring antibiotic resistance (aad(6), ant(6)-Ia, ermB, tet(O), patB, and sat4) and gene clusters (aph(3')-IIIa and aac(6')-Ie-aph(2″)-Ia) associated with aminoglycoside, macrolide, and fluoroquinolone resistance in S. suis in Thailand. This work provides additional resources for future genomic epidemiology investigation of S. suis.
Additive risks of combining supra-aortic trunk surgical reconstruction (SAT) with carotid endarterectomy (CEA) for associated carotid bifurcation and great vessel disease management are not well defined. This study sought to define risk of combining SAT with CEA.

Isolated CEA (ICEA) and CEA+SAT (from 2005 to 2015) were identified from NSQIP, excluding nonocclusive indications. CEA+SAT were compared with ICEA as well as a propensity-matched ICEA cohort. Primary outcomes included 30-day stroke, death, and composite (SD). Outcomes were then weighted by symptomatic status. Univariate and logistic regression analyses were performed.

Patients included 79,477 ICEA and 270 CEA+SAT. SAT reconstructions included 19 (7%) aorto-carotid bypasses, 21 (8%) carotid-subclavian transpositions, 85 (31%) carotid-carotid bypasses, and 145 (54%) carotid-subclavian bypasses. There was no difference in 30-day mortality (vs CEA+SAT 1.5% vs ICEA 0.7% p= 0.12). CEA+SAT had higher rates of stroke (3.7% vs 1.6%, p= 0.005) and strok characteristics, patient longevity, and individual operative risk profile.
In sentinel lymph node (SLN)-positive melanoma, two randomized trials demonstrated equivalent melanoma-specific survival with nodal surveillance vs completion lymph node dissection (CLND). Patients with microsatellites, extranodal extension (ENE) in the SLN, or >3 positive SLNs constitute a high-risk group largely excluded from the randomized trials, for whom appropriate management remains unknown.

SLN-positive patients with any of the three high-risk features were identified from an international cohort. CLND patients were matched 11 with surveillance patients using propensity scores. Risk of any-site recurrence, SLN-basin-only recurrence, and melanoma-specific mortality were compared.

Among 1,154 SLN-positive patients, 166 had ENE, microsatellites, and/or >3 positive SLN. At 18.5 months median follow-up, 49% had recurrence (vs 26% in patients without high-risk features, p < 0.01). Among high-risk patients, 52 (31%) underwent CLND and 114 (69%) received surveillance. Fifty-one CLND patients were matched to 51 surveillance patients. The matched cohort was balanced on tumor, nodal, and adjuvant treatment factors. There were no significant differences in any-site recurrence (CLND 49%, surveillance 45%, p= 0.99), SLN-basin-only recurrence (CLND 6%, surveillance 14%, p= 0.20), or melanoma-specific mortality (CLND 14%, surveillance 12%, p= 0.86).

SLN-positive patients with microsatellites, ENE, or >3 positive SLN constitute a high-risk group with a 2-fold greater recurrence risk. For those managed with nodal surveillance, SLN-basin recurrences were more frequent, but all-site recurrence and melanoma-specific mortality were comparable to patients treated with CLND. Most recurrences were outside the SLN-basin, supporting use of nodal surveillance for SLN-positive patients with microsatellites, ENE, and/or >3 positive SLN.
3 positive SLN.
For patients with cutaneous melanoma, having >1 positive lymph node (LN) is associated with worse survival. We hypothesized that for stage IIIA patients, N2a disease (2 to 3 positive LN) would be associated with a worse prognosis compared to those with N1a disease (1 positive LN).

Stage IIIA melanoma patients in the NCDB Participant User File from 2010 to 2016 were analyzed. Overall survival (OS) between N1a and N2a patients was compared. Subgroup analyses were made between patients undergoing sentinel lymph node (SLN) biopsy alone and those undergoing subsequent completion lymph node dissection (CLND). A separate post hoc analysis of T2a patients undergoing SLN biopsy and CLND from a prospective multicenter randomized clinical trial was performed to validate the findings.

Records of 2,305 IIIA patients were evaluated. In an adjusted survival model, N2a disease was an independent risk factor for worse OS (hazard ratio [HR] 1.56, p= 0.0052). In the subgroup analysis, there was no difference in OS between N1a and N2a disease for patients who underwent SLN biopsy without CLND (p= 0.59), but there was a significant difference in OS for patients who underwent SLN biopsy plus CLND (p= 0.0009). The separate clinical trial database confirmed that for patients with SLN-only disease, there was no difference in OS between N1a and N2a disease.

For stage IIIA melanoma patients, the distribution of micrometastatic lymph node disease (SLN or non-SLN), rather than the absolute number of SLNs, should be considered when individualizing adjuvant therapy recommendations.

Combined hepatocellular-cholangiocarcinoma liver tumors (cHCC-CCA) with pathologic differentiation of both hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma within the same tumor are not traditionally considered for liver transplantation due to perceived poor outcomes. Published results are from small cohorts and single centers. Through a multicenter collaboration, we performed the largest analysis to date of the utility of liver transplantation for cHCC-CCA.

Liver transplant and resection outcomes for HCC (n= 2,998) and cHCC-CCA (n= 208) were compared in a 12-center retrospective review (2009 to 2017). Pathology defined tumor type. Tumor burden was based on radiologic Milan criteria at time of diagnosis and applied to cHCC-CCA for uniform analysis. Kaplan-Meier survival curves and log-rank test were used to determine overall survival and disease-free survival. Cox regression was used for multivariate survival analysis.

Liver transplantation for cHCC-CCA (n= 67) and HCC (n= 1,814) within Milan had no significant difference in overall survival (5-year cHCC-CCA 70.
