Summary
This bibliometric review maps global research on palliative care (PC) and nutrition. The number of publications has steadily increased, with the USA and European countries leading in research output and citations.
Area of Science:
- Palliative Care and Nutrition Research
Background:
- Palliative care (PC) and nutrition are critical components of supportive medical care.
- Understanding research trends in this interdisciplinary field is essential for advancing patient outcomes.
Purpose of the Study:
- To systematically map and analyze international research trends in palliative care and nutrition.
- To identify key countries, institutions, and emerging topics in the field.
Main Methods:
- Bibliometric analysis of articles published between 1970 and 2023.
- Data sourced from the Web of Science (WoS) database using specific keywords.
- Analysis of publication counts, citations, author participation, and keyword frequency.
Main Results:
- A total of 918 articles were identified, with a significant increase in publications from 1991 to 2023.
- The United States of America (USA) led in publications, followed by Germany and France.
- Key research terms included 'palliative care,' 'end,' 'nutrition,' 'quality of life,' 'hydration,' 'cancer,' 'symptoms,' and 'management.'
Conclusions:
- Research in palliative care and nutrition has shown consistent growth.
- The USA and European nations are dominant in publishing and receiving citations in this field.
- Current research hotspots highlight the multifaceted nature of PC and nutrition, encompassing symptom management and quality of life.

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...

02:59Cancer Prevention
6.0K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:21Cancer Survival Analysis
318
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...

02:50Combination Therapies and Personalized Medicine
4.8K
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...

54
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
