Summary
The COVID-19 pandemic spurred a rise in palliative care (PC) publications, particularly those focused on cancer. This trend, however, was only partially driven by pandemic-related research, indicating broader shifts in PC scholarship.
Area of Science:
- Palliative Care Research
- Bibliometrics
- Epidemiology
Background:
- Palliative care (PC) research trends and international collaborations are crucial for understanding global health priorities.
- The COVID-19 pandemic has potentially impacted research output across various medical fields.
Purpose of the Study:
- To analyze the publication trends in palliative care (PC) over the past decade.
- To evaluate the influence of COVID-19 on PC publications and identify key research topics and international collaborations.
Main Methods:
- A bibliometric analysis of palliative care (PC) publications from 2012-2021 using Scopus.
- VOSviewer was employed to analyze keywords for main topics and map country collaborations.
Main Results:
- A notable increase in PC publications occurred during the COVID-19 pandemic (2020-2021), with only a partial contribution from COVID-19 specific research.
- Cancer-related PC publications showed the most significant increase.
- Key research themes included bioethics, cancer, nursing homes, telemedicine, public health, and care aligned with WHO definitions.
- The United States and England were the most prolific collaborating countries.
Conclusions:
- The observed rise in PC publications in the last two years is not solely attributable to COVID-19.
- Cancer-related PC research experienced a marked increase during the pandemic, while publications on heart failure, lung disease, and dementia remained stable.
- International collaboration in PC research is evident, with specific countries leading in publication output.

01:25Continuing Care
1.5K
Continuing care describes the variety of health, personal, and social services provided over a prolonged period. The need for continuing care is increasing because people are living longer. Many people do not have families or others to care for them. Continuing care is mainly for patients who are disabled, functionally dependent, or suffering from a terminal disease. It is available within institutional settings or in homes. Examples include nursing centers or facilities, assisted living,...

01:21Cancer Survival Analysis
410
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

02:49Cancer Therapies
7.9K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

38.6K
The chi-square test is a statistical hypothesis test. It is used to check whether there is a significant difference between an expected value and an observed value. In the context of genetics, it enables us to either accept or reject a hypothesis, based on how much the observed values deviate from the expected values.
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...

5.0K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

00:52Pareto Chart
6.9K
A Pareto chart is a bar graph or a combination of both line and bar graphs. The bar lengths represent the individual values or the frequency, while the lines represent the cumulative total values. In this chart, the longest bars are arranged on the left and the shortest bars on the right, which makes it easier to read and interpret the data. It can also be called a Pareto diagram or Pareto analysis.
The Pareto chart is named after the Italian economist Vilfredo Pareto, who described the Pareto...
