Surgical quality improvement efforts are challenging due to the multidisciplinary nature of care, difficulties obtaining reliable data, and variability in quality metrics. The objective of this analysis was to assess whether participation in a regional collaborative quality initiative was associated with decreased in-hospital surgical complication in South Carolina.

In-hospital surgical complication rates were determined using a statewide all-payer claims data set. Retrospective, univariate, and longitudinal multivariable analyses were performed and adjustments were made to account for aggregated hospital-level patient characteristics.

The analysis included 275,387 general surgery cases performed in South Carolina hospitals between January 2016 and December 2018. Eight hospitals involved in the South Carolina Surgical Quality Collaborative (SCSQC) performed 56,179 cases and 51 non-SCSQC hospitals performed 219,208 cases. Univariate analysis revealed SCSQC hospitals performed operations in older patientsction support, timely data review, and active member participation resulted in outcomes improvements for participating hospitals compared with hospitals that did not participate in a regional collaborative quality initiative.

Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF) is a validated tool for capturing a patient's perception of their physical capacity. LDN-212854 TGF-beta inhibitor The goal of this study was to determine whether preoperative PF correlates with a risk of postoperative complications.

Patients from a single-institution American College of Surgeons NSQIP database undergoing elective colorectal abdominal operations from January 2018 to June 2019 with a preoperative PROMIS-PF T-score were eligible for this retrospective study. Patients were divided into moderate to severe (score <40) and minimal to mild (score ≥40) physical disability cohorts. Primary outcomes were any complication and any Clavien-Dindo grade III or higher complication. Multivariate logistic regression was performed.

In total, 249 patients were included 78 (31%) with self-scored moderate to severe disability and 171 (69%) with minimal to mild disability. Patients who scored as moderate to severe disability had a higher frequency erative complications among patients undergoing colorectal operations. PROMIS-PF T-score can be a useful tool to identify patients who would benefit from targeted preoperative interventions, such as patient education, nutritional optimization, and prehabilitation.

The prognostic impact of colorectal liver metastasis (CRLM) morphologic characteristics relative to KRAS mutational status after hepatic resection remains ill defined.

Patients undergoing hepatectomy for CRLM between 2001 and 2018 were identified using an international multi-institutional database. Tumor burden score (TBS) was defined as distance from origin on a Cartesian plane that incorporated maximum tumor size (x-axis) and number of lesions (y-axis). Impact of TBS on overall survival (OS) relative to KRAS status (wild type [wtKRAS] vs mutated [mutKRAS]) was assessed.

Among 1,361 patients, the median number of metastatic lesions was 2 (interquartile range [IQR] 1-3), and median size of the largest metastatic lesion was 3.0 cm (IQR 2.0-5.0 cm), resulting in a median TBS of 4.1 (IQR 2.8-6.1); KRAS status was wtKRAS (n= 420, 30.9%), mutKRAS (n= 251, 18.4%), and unknown (n= 690, 50.7%). Overall median and 5-year OS were 49.5 months (95%CI 45.2-53.8) and 43.2%, respectively. In examining the entire cohorterm outcomes among patients with mutKRAS CRLM.

While TBS was associated with survival among patients with wtKRAS tumors, CRLM morphology was not predictive of long-term outcomes among patients with mutKRAS CRLM.Smart nanocarriers obtained from bacteria and viruses offer excellent biomimetic properties which has led to significant research into the creation of advanced biomimetic materials. Their versatile biomimicry has application as biosensors, biomedical scaffolds, immobilization, diagnostics, and targeted or personalized treatments. The inherent natural traits of biomimetic and bioinspired bacteria- and virus-derived nanovesicles show potential for their use in clinical vaccines and novel therapeutic drug delivery systems. The past few decades have seen significant progress in the bioengineering of bacteria and viruses to manipulate and enhance their therapeutic benefits. From a pharmaceutical perspective, biomimetics enable the safe integration of naturally occurring bacteria and virus particles to achieve high, stable rates of cellular transfection/infection and prolonged circulation times. In addition, biomimetic technologies can overcome safety concerns associated with live-attenuated and inactivated whole bacteria or viruses. In this review, we provide an update on the utilization of bacterial and viral particles as drug delivery systems, theranostic carriers, and vaccine/immunomodulation modalities.Interest is increasing in the use of nanotheranostics as diagnosis, imaging and therapeutic tools for stroke management, but movement to the clinic remains challenging.Patients in whom mismatch repair (MMR)-deficient cancer develops in the absence of pathogenic variants of germline MMR genes or somatic hypermethylation of the MLH1 gene promoter are classified as having suspected Lynch syndrome (SLS). Germline whole-genome sequencing (WGS) and targeted and genome-wide tumor sequencing were applied to identify the underlying cause of tumor MMR deficiency in SLS. Germline WGS was performed on samples from 14 cancer-affected patients with SLS, including two sets of first-degree relatives. MMR genes were assessed for germline pathogenic variants, including complex structural rearrangements and noncoding variants. Tumor tissue was assessed for somatic MMR gene mutations using targeted, whole-exome sequencing or WGS. Germline WGS identified pathogenic MMR variants in 3 of the 14 cases (21.4%), including a 9.5-megabase inversion disrupting MSH2 in a mother and daughter. Excluding these 3 MMR carriers, tumor sequencing identified at least two somatic MMR gene mutations in 8 of 11 tumors tested (72.
