Activity

To document clinical, radiologic, and cellular data of a prospective patient series treated by a tri-layer collagen-hydroxyapatite biomimetic osteochondral scaffold (CHAS) intra-operatively seeded with cultivated autologous chondrocytes (AC) or with filtered bone marrow stem/stromal cells (fBMSC) to address chronic osteochondral knee lesions.

Thirty-six consecutive patients (15 to 59years) with chronic osteochondral lesions (1.8-10cm

) in the condylar or patellofemoral knee surfaces were enrolled. Lesions were covered with CHAS fixed with a fibrin glue. The superficial layer of CHAS was intra-operatively injected with active cells in initial fivepatients, ACs were put directly onto dry CHAS (dry-AC); next, eightAC patients had CHAS moistened with cell culture media (media-AC), while the tourniquet was released allowing blood soaking of CHAS in the rest (14 blood-AC, 9 blood-fBMSC). Seventeen (50%) patients required different concomitant procedures. All patients were followed for serious adverse events (Sollows cells in suspension 9.2 × 10

, viability 95%. In blood-fBMSC group, a cell suspension with 87% viability was injected, which contained 1156 CFU-Fs.

CHAS with intra-operative seeding of active cells, either AC or fBMSC, led to an overall successful outcome for the treatment of chronic osteochondral lesions in the knee. Blood soaking of CHAS in situ before cell seeding significantly decreased early post-operative adverse events, such as synovitis and arthrofibrosis.

Bariatric surgery is the only effective treatment of severe obesity. The number of adolescents undergoing bariatric surgery is increasing. However, bariatric surgery in adolescents is controversial.

The purpose of this study is to evaluate the outcomes of bariatric surgery in adolescents based on the MBSAQIP database (Metabolic and Bariatric Surgery Accreditation and Quality Improvement Project).

We analyzed the 2015-2017 MBSAQIP database; patients ≤ 19years of age were included in our analysis. Primary outcomes were 30-day serious adverse events (SAEs), organ space infection (OSI), re-intervention, and re-operation rates. Secondary outcomes included operation length, hospital stay, and re-admission rates. We conducted separate Mann-Whitney rank sums tests, chi-square, or Fisher’s exact tests as appropriate, with p < .05 denoting statistical significance.

A total of 1983 adolescent patients were included in our analysis. The average age and BMI were 18.1 and 47.5, respectively. Of adolescent patients, 21.7% underwent laparoscopic Roux-en-Y gastric bypass (LRYGB) and 78.3% underwent laparoscopic sleeve gastrectomy (LSG). The 30-day SAE and readmission rates were significantly lower for LSG compared with LRYGB (2.9% and 2.6% vs 6.5% and 5.6%, respectively; p < 0.05). The 30-day reoperation rate was also lower for LSG compared with LRYGB albeit not significant (1.1% and vs 2.3%; p = 0.05). The 30-day intervention rate for LSG was significantly lower, however, compared with LRYGB (1.2% vs 3%; p < 0.05). Compared with adult patients, > 19years old (n = 353,726), we found no difference in our outcomes. However, adolescents had significantly shorter operation length.

In adolescents, LSG had fewer SAE, re-intervention, and readmission rates compared with LRYGB. There was no difference in outcomes between adolescents and adults.

The American College of Surgeons tracks 30-day outcomes using the Metabolic and Bariatric Surgery Accreditation Quality Initiative Program (MBSAQIP) database. We examined the short-term outcomes of patients that undergo bariatric surgery concomitantly with other operations such as hernia repairs and cholecystectomy to determine the safety of this practice.

The MBSAQIP Participant Use Data File for 2015-2017 was examined for differences in primary bariatric operations vs concomitant procedures (CP). We looked for concurrent CPT codes for laparoscopic cholecystectomy (LC) and hernia repairs (ventral, epigastric, incisional, and inguinal). Epigenetic inhibitor order p was significant at < 0.05.

There were 464,674 cases, of which 15,614 had CP. For both LRYGB+LC and SG+LC, there were increased operative times and length of stay. There were statistically significant higher rates of readmission, reintervention, and reoperation for SG+LC vs SG alone, as well as for LRYGB+hernia and SG+hernia. There was a higher risk of death (p < time of bariatric surgery should be deferred if possible.

The importance of long noncoding RNAs (lncRNAs) has been identified in human cancers, such as emerged as tumor facilitator or tumor suppressor. Small nucleolar RNA host gene 10 (SNHG10) has been reported as an oncogenic lncRNA in hepatocellular carcinoma. However, its functional role and underlying mechanism in gastric cancer (GC) need to be further explored.

Our study was conducted to investigate the function and molecular mechanism of SNHG10 in GC.

SNHG10 expression was detected by qRT-PCR. The effect of SNHG10 on GC cell growth was assessed by colony formation, EdU, JC-1, flow cytometry, and wound-healing assays. The interaction between SNHG10 and PBX3 was confirmed through ChIP and luciferase reporter assay. RIP and RNA pull down assays was used to define the binding of DEAD-box helicase 54 (DDX54) to SNHG10 or PBX homeobox 3 (PBX3).

SNHG10 was expressed at a high level in GC cells. SNHG10 knockdown resulted in the inhibition on GC cell proliferation, migration but induced cell apoptosis. PBX3 could interact with SNHG10 promoter and thereby activate the expression of SNHG10. Subsequently, it was confirmed that SNHG10 positively modulated the expression of PBX3. Based on this, we found that DDX54 could bind to SNHG10 and PBX3, suggesting that SNHG10 maintained PBX3 mRNA stability through recruiting DDX54. Restoration assays indicated that PBX3 overexpression recovered SNHG10 silencing-induced inhibition on GC cell growth.

SNHG10 facilitates cell growth by affecting DDX54-mediated PBX3 mRNA stability in GC.
