Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Surgery
  • Cardiology

His primary areas of study are Internal medicine, Cardiology, Surgery, Angioplasty and Prospective cohort study. His Cohort, Heart disease, Ejection fraction, Heart failure and Risk factor investigations are all subjects of Internal medicine research. His Cardiology study frequently draws connections between adjacent fields such as Disease.

The concepts of his Angioplasty study are interwoven with issues in Bypass surgery, Balloon, Lung and Revascularization. His Prospective cohort study research is multidisciplinary, incorporating elements of Cohort study, Pediatrics and Intensive care. His Coronary artery disease study integrates concerns from other disciplines, such as Angiography, Stenosis, Ischemia, Chest pain and Angina.

His most cited work include:

  • Identification of children at very low risk of clinically-important brain injuries after head trauma: a prospective cohort study (973 citations)
  • Percutaneous Transluminal Coronary Angioplasty in 1985–1986 and 1977–1981 (787 citations)
  • Controlled trial of intravenous immune globulin in recent-onset dilated cardiomyopathy (409 citations)

What are the main themes of his work throughout his whole career to date?

Richard Holubkov mostly deals with Internal medicine, Cardiology, Surgery, Prospective cohort study and Pediatrics. His study in Endocrinology extends to Internal medicine with its themes. Richard Holubkov regularly links together related areas like Blood pressure in his Cardiology studies.

Richard Holubkov has researched Surgery in several fields, including Angioplasty and Cohort. The various areas that Richard Holubkov examines in his Prospective cohort study study include Cohort study, Intensive care, Intensive care medicine, Emergency medicine and Severity of illness. Richard Holubkov usually deals with Pediatrics and limits it to topics linked to Clinical trial and Hypothermia.

He most often published in these fields:

  • Internal medicine (41.56%)
  • Cardiology (28.75%)
  • Surgery (27.81%)

What were the highlights of his more recent work (between 2017-2021)?

  • Internal medicine (41.56%)
  • Pediatrics (13.44%)
  • Randomized controlled trial (12.50%)

In recent papers he was focusing on the following fields of study:

Richard Holubkov mainly investigates Internal medicine, Pediatrics, Randomized controlled trial, Cohort and Hypothermia. His work on Internal medicine is being expanded to include thematically relevant topics such as Cardiology. His Cardiology research integrates issues from Cardiopulmonary resuscitation and Blood pressure.

His Randomized controlled trial research focuses on subjects like Vineland Adaptive Behavior Scale, which are linked to Survival analysis and Mechanical ventilation. In his research on the topic of Cohort, Etiology, Prospective cohort study and Antibiotics is strongly related with Hydrocephalus. His Surgery research includes themes of Cohort study and Heart failure.

Between 2017 and 2021, his most popular works were:

  • A Plant-Based Dietary Intervention Improves Beta-Cell Function and Insulin Resistance in Overweight Adults: A 16-Week Randomized Clinical Trial. (31 citations)
  • Chest compression rates and pediatric in-hospital cardiac arrest survival outcomes. (28 citations)
  • A plant-based diet in overweight individuals in a 16-week randomized clinical trial: metabolic benefits of plant protein. (25 citations)

In his most recent research, the most cited papers focused on:

  • Internal medicine
  • Surgery
  • Disease

His primary areas of investigation include Internal medicine, Hypothermia, Pediatrics, Randomized controlled trial and Blood pressure. His Internal medicine study incorporates themes from Endocrinology and Cardiology. His Hypothermia research is multidisciplinary, incorporating perspectives in Resuscitation, Targeted temperature management and Extracorporeal membrane oxygenation.

His Pediatrics research includes elements of Logistic regression, Mechanical ventilation, Mood, Cohort and Traumatic brain injury. Richard Holubkov interconnects Overweight, Vineland Adaptive Behavior Scale and Insulin resistance in the investigation of issues within Randomized controlled trial. His Blood pressure research is multidisciplinary, relying on both Anesthesia, Intensive care, Cardiopulmonary resuscitation and Intensive care unit.
