What is Population Genetics?

64.7K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Emerging Adulthood01:27

Emerging Adulthood

681
Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...

Conservation of Small Populations02:04

Conservation of Small Populations

17.2K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Population Growth00:57

Population Growth

28.4K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Introduction Cardiac Emergencies

339
Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...

Summary
This summary is machine-generated.

Nearly one-fifth of patients undergoing emergency general surgery (EGS) experienced readmission within six months. One in nine readmitted patients required a second EGS procedure, highlighting the need to identify high-risk individuals for better outcomes.

Area of Science:

  • General Surgery
  • Health Services Research
  • Epidemiology

Background:

  • Limited data exist on long-term outcomes following emergency general surgeries (EGS) in the United States.
  • This study addresses this gap by examining readmissions and reoperations within six months of EGS.

Purpose of the Study:

  • To characterize the incidence of inpatient readmissions after EGS.
  • To determine the rate of additional operations within six months of an initial EGS procedure.
  • To identify risk factors associated with reoperation after EGS.

Main Methods:

  • Retrospective observational study using the 2010-2015 National Readmissions Database.
  • Included adults (≥18 years) undergoing one of seven common EGS procedures.
  • Analyzed all-cause inpatient readmissions and second EGS procedures within six months, using multivariable logistic regression to identify risk factors.

Main Results:

  • 18.6% of 706,678 patients had an inpatient readmission within six months.
  • 11.6% of readmitted patients (15,178) underwent a second EGS procedure.
  • Key predictors of reoperation included male sex, specific hospital types, discharge disposition, and index procedure type (e.g., GI ulcer/bleeding control, laparotomy, large bowel resection).

Conclusions:

  • One-fifth of patients undergoing EGS experienced readmission, with one in nine requiring a second EGS procedure.
  • Half of second EGS procedures occurred within six weeks of the index surgery.
  • Identifying patients at high risk for reoperation based on index procedure and discharge needs is crucial for improving care in non-emergency settings.
