Weighted Mean00:57

Weighted Mean

6.6K
While taking the arithmetic, geometric, or harmonic mean of a sample data set, equal importance is assigned to all the data points. However, all the values may not always be equally important in some data sets. An intrinsic bias might make it more important to give more weightage to specific values over others.
For example, consider the number of goals scored in the matches of a tournament. While computing the average number of goals scored in the tournament, it may be more important to...

Atomic Weight01:25

Atomic Weight

14.1K
Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams. Scientists arbitrarily define this amount of mass as one atomic mass unit (amu) or one Dalton. Electrons are much smaller in mass than protons, weighing only 9.11 × 10-28 grams, or about 1/1800 of an atomic mass unit. As a result, they do not contribute much to an element's overall atomic mass. This means that, when considering atomic mass, it is customary to ignore the mass of any electrons and...

Mass and Weight01:19

Mass and Weight

15.6K
Mass and weight are often used interchangeably in everyday conversation. For example,  medical records often show our weight in kilograms, but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of the Earth on an object. It depends on the distance from the center of the Earth. Weight dramatically varies if we leave the Earth's surface, unlike mass, which does not vary with location. On the Moon, for example, the...

Apparent Weight01:09

Apparent Weight

9.9K
True weight is the measure of the gravitational force acting on an object. However, if the object accelerates, its measured weight is different from its true weight. Similar observations can be made when the object is submerged in water. An object's weight in water is its apparent weight, which is equal to the difference between its true weight and the buoyant forces.
Consider a person standing on a bathroom scale inside an elevator. If the scale is accurate at rest, its reading equals the...

Global Climate Change

29.1K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Rates of Change01:20

Rates of Change

143
The rate of change is a central concept in mathematics that quantifies how one variable varies in response to another. It serves as a foundational tool in modeling dynamic systems across disciplines such as physics, biology, economics, and engineering. Understanding both average and instantaneous rates of change enables the analysis of behavior in functions that describe real-world phenomena.Average Rate of ChangeFor a function f(x) defined over an interval [x1,x2], the average rate of change...

Summary
This summary is machine-generated.

Total thyroidectomy does not lead to significant weight gain, even in patients with preoperative hyperthyroidism. This study found no evidence of post-surgical weight changes beyond normal fluctuations.

Area of Science:

  • Endocrinology
  • Surgical Oncology
  • General Surgery

Background:

  • A common belief suggests total thyroidectomy leads to weight gain, irrespective of thyroid hormone replacement therapy.
  • This study investigates the validity of this perception in patients undergoing total thyroidectomy for various thyroid conditions.

Purpose of the Study:

  • To determine if patients experience significant weight gain after total thyroidectomy.
  • To identify factors that might predict weight gain post-thyroidectomy.

Main Methods:

  • Retrospective analysis of 107 total thyroidectomy patients (Jan 2013 - June 2014).
  • Review of medical records for pathology, thyroid status, medications, and preoperative weight.
  • Follow-up data (≥10 months) collected from 79 patients for current weight and management details.

Main Results:

  • Mean weight change was a non-significant increase of 0.06 ± 6.9 kg (P = 0.094).
  • No significant weight change was observed, regardless of preoperative thyroid function.
  • Preoperative hyperthyroidism, female gender, and antithyroid drug use did not predict weight gain.

Conclusions:

  • Total thyroidectomy does not result in significant weight gain across a spectrum of thyroid pathologies.
  • Patient weight remains stable post-thyroidectomy when thyroid hormone levels are normalized.
