DNA nanotechnology for cell-free DNA marker for tumor detection: a comprehensive overview.

Advancements in DNA nanotechnology have led to new exciting ways to detect cell-free tumor biomarkers, revolutionizing cancer diagnostics. This article comprehensively reviews recent developments in this field, discussing the significance of liquid biopsies and DNA nanomachines in early cancer detection. The accuracy of cancer diagnosis at its early stages is expected to be significantly improved by identifying biomarkers.

Effects of Preoperative COVID-19 Status on Emergent or Urgent Colectomy Outcomes.

Objectives: Severe acute respiratory syndrome coronavirus 2 has been described as eliciting a powerful immune response. The association of coronavirus disease 2019 (COVID-19) infection with diseases requiring emergent or urgent colectomies may exacerbate the risk of surgical complications. We investigated the effect of preoperative COVID-19 infection on the clinical outcomes of patients who underwent a nonelective colectomy in 2021.

Racial Disparities in Clinical Outcomes of Emergency Colectomies for Diverticulitis.

Objectives: The literature suggests that there are ongoing racial disparities in healthcare outcomes between patients in White and non-White populations. As such, we examined the outcomes of patients who underwent an emergency colectomy for diverticulitis.

Methods: We identified 4841 White and 590 non-White patients, which include Black/African American and Asian patients, using the 2016-2019 American College of Surgeons National Surgical Quality Improvement Program databases.

New legislation in New Jersey reduced opioid use among trauma patients.

Purpose: In New Jersey, politicians have emphasized the need to attenuate the ongoing opioid epidemic as opioid use disorder can lead to addiction and, in many cases, mortality. New legislation (New Jersey Senate Bill 3) was enacted in 2017 to reduce opioid prescription from 30 days to 5 days for acute pain in both inpatient and outpatient healthcare settings. Therefore, we sought to evaluate if the enactment of the bill influenced the consumption of opioid pain medication at an American College of Surgeons-verified Level I Trauma Center.

Assessment of Risk Factors for Iatrogenic Genitourinary Injuries During a Proctectomy.

Background: It is critical to avoid iatrogenic injuries affecting genitourinary organs in order to prevent postoperative urinary or sexual dysfunction, which lead to lengthier recovery and possibly reoperation.

Methods: Using the 2016-2019 American College of Surgeons National Quality Improvement Program (ACS NSQIP) Targeted Proctectomy Database, we collated 2577 patients with non-metastatic rectal cancer who underwent a laparoscopic or open proctectomy. Univariate analysis was used to identify differences in perioperative factors and genitourinary injuries (GUIs) between operative approaches, and multivariate logistic regression was used to identify independent risk factors for sustaining an intraoperative GUI.

The Effects of the COVID-19 Pandemic on Mastectomy Outcomes for Breast Cancer.

Background: Single center studies have shown that during the Coronavirus Disease 2019 (COVID-19) pandemic, many patients had surgical procedures postponed or modified. We studied how the pandemic affected the clinical outcomes of breast cancer patients who underwent mastectomies in 2020.

Methods: Using the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database, we compared clinical variables of 31,123 and 28,680 breast cancer patients who underwent a mastectomy in 2019 and 2020, respectively.

Comparing carotid endarterectomies with or without shunting in symptomatic and asymptomatic patients.

Background: Recent research shows that placement of an intraluminal shunt during a carotid endarterectomy (CEA) can be associated with postoperative complications. Therefore, we compared CEA operations with or without shunting to further analyze their clinical outcomes.

Methods: From the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database, 13,736 cases between 2016 and 2019 were analyzed to compare adult symptomatic and asymptomatic carotid stenosis patients who underwent a CEA operation, with or without shunt placement.

A Single-Institution Comparison of Robot-Assisted and Conventional Laparoscopic Colorectal Surgeries.

There has been ongoing discussion regarding the superiority of robotic laparoscopic surgery (RLS) over conventional laparoscopic surgery (CLS) in many surgical subspecialties. We therefore sought to elucidate if RLS is associated with more favorable clinical outcomes than CLS among patients who underwent colorectal surgery. Using data from a high-volume single institution in New Jersey, we identified 145 patients who underwent an elective RLS or CLS sigmoid resection for colon cancer or diverticulitis in 2019 and 2020.

Vessel Sealant Devices in Thyroidectomies: An ACS-NSQIP Study.

Objectives: Thyroidectomies involve meticulous dissection of a highly vascularized organ and complications may develop, such as hematoma, hypocalcemia, and even hypoparathyroidism. Because some of these complications may be fatal, we sought to identify the differences in postthyroidectomy outcomes when the use of a vessel sealant device (VSD) such, as LigaSure or Harmonic scalpel, is compared with more traditional techniques, such as ligatures and clips.

Methods: Using the 2016 American College of Surgeons National Surgical Quality Improvement Program Targeted Thyroidectomy database, we compared patients who underwent a thyroidectomy using a VSD with patients without a VSD for differences in postoperative complications.

Association Between Body Mass Index and Morbidity and Mortality During Hospitalization After Trauma.

Background: Literature suggests that unhealthy body mass index is a risk factor for adverse clinical outcomes.

Objectives: To study the association between unhealthy body mass index and morbidity and mortality after trauma using the 2016 American College of Surgeons Trauma Quality Improvement Program database.

Methods: A retrospective review was conducted comparing the normal weight control group to the underweight, overweight, obese, severely obese, and morbidly obese groups for differences in demographic factors, injury severity score, comorbidities, length of stay, and complications.

Analysis of Perioperative Risk Factors for Clostridium difficile Infection After a Colectomy.

Introduction The removal of the terminal ileum may interfere with gut-associated lymphoid tissue function, reduce bile salt reabsorption, and change intraluminal pH, which may contribute to the development of infection (CDI) after ileocolic resections. Therefore, we compared CDI incidence among patients who underwent a colectomy with or without removal of the terminal ileum. Methods Using the 2016 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Targeted Colectomy database, we identified 17,962 patients who underwent a left-sided colectomy without removal of the terminal ileum and 5,929 patients who underwent an ileocolic resection involving the removal of the terminal ileum.

The impact of gender on clinical outcomes after sustaining a pelvic fracture.

Introduction: In trauma care, pelvic fractures contribute to morbidity and mortality. Since men and women have different pelvic structures and hormonal milieu, we studied if these gender differences affect clinical outcomes after pelvic fractures.

Methods: Using the 2016 American College of Surgeons Trauma Quality Improvement Program (ACS TQIP) database, we stratified 24,425 patients with pelvic fractures by gender.

The impact of BMI on morbidity and mortality after femoral fractures.

Purpose: Femur fractures are the result of high energy injury and are associated with life-threatening complications. Therefore, we studied how body mass index (BMI) contributes to complications after femoral fractures.

Methods: Using the 2016 American College of Surgeons Trauma Quality Improvement Program (ACS TQIP) database, we stratified 41,362 patients into groups based on their BMI: Normal Weight (NW), Overweight (OW), Obese (OB), Severely Obese (SO), and Morbidly Obese (MO).

Semantic Clustering of Search Engine Results.

This paper presents a novel approach for search engine results clustering that relies on the semantics of the retrieved documents rather than the terms in those documents. The proposed approach takes into consideration both lexical and semantics similarities among documents and applies activation spreading technique in order to generate semantically meaningful clusters. This approach allows documents that are semantically similar to be clustered together rather than clustering documents based on similar terms.
