Combined and intraoperative risk modelling for oesophagectomy: A systematic review.

Background: Oesophageal cancer is the eighth most common malignancy worldwide and is associated with a poor prognosis. Oesophagectomy remains the best prospect for a cure if diagnosed in the early disease stages. However, the procedure is associated with significant morbidity and mortality and is undertaken only after careful consideration.

Association of Successful Percutaneous Revascularization of Chronic Total Occlusions With Quality of Life: A Systematic Review and Meta-Analysis.

Importance: Chronic total occlusion percutaneous coronary intervention (CTO-PCI) is not usually offered because of skepticism about long-term clinical benefits.

Objective: To assess the association of successful CTO-PCI with quality of life by analyzing the relevant domains of the Seattle Angina Questionnaire (SAQ).

Data Sources: PubMed, EMBASE, Web of Science, Google Scholar, and Cochrane databases were searched to identify randomized trials and observational studies specifically addressing quality of life domains of SAQ from January 2010 to June 2022.

Hospital-Level Variability in Use of Intracoronary Imaging for Percutaneous Coronary Intervention in the United States.

Background: Intracoronary (IC) imaging for percutaneous coronary intervention (PCI) is associated with better patient outcomes and carries a class IIA guideline recommendation, but it remains rarely used. We sought to characterize hospital-level variability in IC imaging for PCI in the United States and to identify factors that may explain this variability.

Methods: Patients who underwent PCI, with or without IC imaging, in the Nationwide Readmissions Database (2016-2020) were included.

Preoperative risk modelling for oesophagectomy: A systematic review.

Background: Oesophageal cancer is a frequently observed and lethal malignancy worldwide. Surgical resection remains a realistic option for curative intent in the early stages of the disease. However, the decision to undertake oesophagectomy is significant as it exposes the patient to a substantial risk of morbidity and mortality.

Validation of the new PROGRESS-CTO complication risk scores in the OPEN-CTO registry.

Methods: OPEN-CTO is a prospective registry of 1000 consecutive CTO PCIs performed at 12 experienced US centers using the hybrid algorithm.

Routine Esophagograms After Hiatus Hernia Repair Minimizes Reoperative Morbidity: A Multicenter Comparative Cohort Study.

Objective: Determine the utility of routine esophagograms after hiatus hernia repair and its impact on patient outcomes.

Background: Hiatus hernia repairs are common. Early complications such asre-herniation, esophageal obstruction and perforation, although infrequent, incur significant morbidity.

Development and validation of a prediction model for angiographic perforation during chronic total occlusion percutaneous coronary intervention: OPEN-CLEAN perforation score.

Background: Perforation is the most frequent complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) and is associated with adverse events including mortality.

Methods: Among 1,000 consecutive patients enrolled in 12 center prospective CTO PCI study (OPEN CTO), all perforations were reviewed by the angiographic core-lab. Eighty-nine patients (8.

Impact of Pool Testing in Detection of Asymptomatic Patients with COVID-19.

Objective: During the current pandemic, COVID-19 has been detected in patients using real-time reverse transcriptase-polymerase chain reaction (RT-PCR) that confirms the presence of SARS-CoV-2 RNA. The demand for increased testing, particularly for asymptomatic individuals required alternative approaches to single-patient RT-PCR testing, such as pooling.

Methods: This study explored the impact of dilution on the detectability of SARS-CoV-2 in asymptomatic patients using RT-PCR and demonstrated that pooling can be effective in low prevalence populations.

SARS-CoV-2 viral load assessment in respiratory samples.

Real-time reverse transcriptase polymerase chain reaction (rRTPCR) has been the main method for diagnosis of SARS-CoV-2 infection in the early stages of the COVID-19 pandemic. De-identified results from upper and lower respiratory samples submitted to a reference laboratory demonstrated a positivity rate of 14.9 % (4428 of 29,713 samples tested).

Management of Percutaneous Coronary Intervention Complications: Algorithms From the 2018 and 2019 Seattle Percutaneous Coronary Intervention Complications Conference.

Complications of percutaneous coronary intervention (PCI) may have significant impact on patient survival and healthcare costs. PCI procedural complexity and patient risk are increasing, and operators must be prepared to recognize and treat complications, such as perforations, dissections, hemodynamic collapse, no-reflow, and entrapped equipment. Unfortunately, few resources exist to train operators in PCI complication management.

Neuro-hormonal Regulation Is a Better Indicator of Human Cognitive Abilities Than Brain Anatomy: The Need for a New Paradigm.

Human intelligence has been theorized since the ancient Greeks. Plato and Aristotle incorporated theories of human intelligence into their metaphysical and cosmological theories which informed the social and medical sciences for centuries. With the advent of the 20th century, human intelligence became increasingly standardized based on Intelligence Quotients (IQ).

Outcomes of Chronic Total Occlusion Percutaneous Coronary Intervention in Patients With Renal Dysfunction.

Although contemporary chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is performed with high success rates, 10% to 13% of patients presenting with CTOs have chronic kidney disease (CKD), and the comparative safety, efficacy, and health status benefit of CTO PCI in these patients, has not been well defined. We examined the association of baseline renal function with periprocedural major adverse cardiovascular and cerebral events and health status outcomes in 957 consecutive patients (mean age 65.3 ± 10.

Examining the Operator Learning Curve for Percutaneous Coronary Intervention of Chronic Total Occlusions.

Background: Advances in chronic total occlusion percutaneous coronary intervention (CTO PCI) techniques have led to increased procedural success rates among operators. While utilization of CTO PCI has disseminated widely, the learning curve for new operators has not been well-defined.

Methods: Between July 2009 and December 2015, 93 875 CTO PCI cases were extracted from the CathPCI Registry.

Anti-anginal medication titration among patients with residual angina 6-months after chronic total occlusion percutaneous coronary intervention: insights from OPEN CTO registry.

Aims: Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has been shown to reduce angina and improve quality of life, but the frequency of new or residual angina after CTO PCI and its relationship with titration of anti-anginal medications (AAMs) has not been described.

Methods And Results: Among consecutive CTO PCI patients treated at 12 US centres in the OPEN CTO registry, angina was assessed 6 months after the index PCI using the Seattle Angina Questionnaire (SAQ) Angina Frequency scale (a score <100 defined new or residual angina). We then compared the proportion of patients with AAM escalation (defined as an increase in the number or dosage of AAMs between discharge and follow-up) between those with and without 6-month angina.

A sex stratified outcome analysis from the OPEN-CTO registry.

Introduction: Women have been under-represented in trials. Due to the dearth of information about CTO-PCI in women and discordance of previous results, sex differences in outcomes in the OPEN-CTO Trial were investigated.

Methods: OPEN-CTO is an investigator-initiated, multicenter, prospective observational registry of consecutive CTO patients undergoing PCI at 12 U.

"Messing with the mind": evolutionary challenges to human brain augmentation.

The issue of brain augmentation has received considerable scientific attention over the last two decades. A key factor to brain augmentation that has been widely overlooked are the complex evolutionary processes which have taken place in evolving the human brain to its current state of functioning. Like other bodily organs, the human brain has been subject to the forces of biological adaptation.

Adiposity is associated with improved neuromuscular reaction time.

Many studies have focused on the detrimental effects of malnourishment to the performance of the brain and peripheral nerves. Undernourished children and adults have been studied extensively to establish these consequences. Little attention has been given to the body habitus that affects optimum neurological performance and the implications for individuals on the spectral extremes of the healthy weight range.
