Abstract Due to the loss of DNA repair mechanisms in colorectal cancer (CRC) with microsatellite instability (MSI), somatic mutations accumulate within DNA; making them more prone attack by tumor infiltrating lymphocytes (TIL) and macrophages. We hypothesize that MSI-High (MSI-H) patients have favorable survival due increased immunogenicity. The Cancer Genome Atlas (TCGA) was used evaluate gene expression from 283 CRC, comparing MSI-H stable (MSS) patients. CIBERSORT algorithm estimated...

Background: The corona virus disease of 2019 (COVID-19) imposed new public health constraints that deterred people from coming to the hospital. outcome patients who developed appendicitis during mandated COVID-19 quarantine has yet be examined. main objective was establish whether there an increased rate perforated seen quarantine. Secondary objectives included observing type procedure performed, length stay, and associated complications.

microRNA-143 (miR-143) is a well-known tumor suppressive microRNA that exhibits anti-tumoral function by targeting KRAS signaling pathways in various malignancies. We hypothesized miR-143 suppresses breast cancer progression and its effector molecules. further high expression of associated with favorable immune microenvironment estrogen receptor (ER)-positive patients which result improved survival. Two major publicly available cohorts; The Cancer Genome Atlas (TCGA) Molecular Taxonomy...

Background and Objectives Surgical management of colorectal cancer liver metastases continues to evolve optimize oncologic outcomes while maximizing parenchymal preservation. Long‐term data after intraoperative microwave ablation are limited. This study investigates patterns recurrence in patients who underwent ablation. Methods A retrospective analysis 33 from 2009 2013 at our institution was performed. Perioperative long‐term were reviewed determine recurrence. Results total 49 tumors...

The purpose of this study was to characterize disparities among centers performing major surgery for esophageal or gastric cancer stratified by case volume.The National Cancer Data Base (NCDB) queried cases esophagectomy total gastrectomy. Centers were compared based on number during 2004-2013: low volume [1-99], middle [100-200], and high [>200].For esophagectomy, 17,547 patients included; 73.5% treated in centers, 14.6% middle, 11.9% high. For gastrectomy, 20,059 included, with 87.5%,...

Laparoscopic and robotic hernia surgery offers advantages over open herniorrhaphy including faster recover lower wound infection but is associated with rare serious complications such as visceral injury intestinal obstruction. We describe two cases of small bowel obstruction strangulation that occurred shortly after routine surgery. define this type strangulating internal a peritoneal pocket call attention to its diagnosis management.

Background The purpose of this study was to determine whether neoadjuvant and/or perioperative chemotherapy (NAC) has an overall survival (OS) benefit for patients with T2N0 gastric adenocarcinoma. Study Design We performed retrospective analyses using the National Cancer Data Base, 2004‐2013. Patients adenocarcinoma were divided into two treatment groups: (1) NAC plus surgery (NA + S) and (2) alone (S). Results Of 1,704 included, 277 (16.3%) received NAC, 1,427 (83.7%) treated alone. in NA...

Molecular analysis has been performed on a Malaysian patient with severe bleeding disorder due to factor XIII A subunit deficiency. Total mRNA was isolated from the patient's leucocytes and four overlapping segments corresponding entire coding region of cDNA were amplified by RT‐PCR. The efficiently expected size. Direct sequencing complete reading frame revealed single homozygous base change (nt 1327G→T) in exon 10 missense mutation, Val414Phe, catalytic core domain monomer. mutation...

Pedestrian and cyclist safety are not considered by urban planners or road users in India. Data on crashes tend to underreport involving this group. In spite of adopting a Non-Motorised-Transport (NMT) friendly policy 2014, Chennai city Tamil Nadu continues prioritise motorised transport. Five years after the NMT Policy adoption, pedestrian infrastructure was assessed 11 locations. A perception survey 37 also conducted as calls for changing mindset motorists towards pedestrians.

473 Background: Neoadjuvant chemotherapy is increasingly being utilized for locally advanced (LAPC)/borderline resectable pancreatic cancer (BRPC); however, long term follow up data sparse. At our institution, we use FOLFIRINOX as the regimen of choice. Gemcitabine (Gem) and nab-Paclitaxel (Abraxane) in patients not suited or if they have poor radiographic response and/or develop significant toxicities to FOLFIRINOX. The aim this study was report institutional experience with neoadjuvant...

Background: Follicular neoplasm (Bethesda IV cytology) requires thyroid lobectomy for diagnosis. Approximately 15-30% of cases are ultimately malignant, requiring reoperative completion thyroidectomy. We sought to reassess whether intraoperative frozen section (FS) reduces the need thyroidectomy in these cases. Methods: A retrospective chart review fine needle aspiration (FNA) results showing follicular from 2003 2012 was performed. Our practice is offer with FS patients; suspicious FS,...
