Summary
The COVID-19 pandemic disrupted gastric cancer care, leading to delayed diagnoses and advanced-stage cancers. Innovations like telemedicine and vaccination helped services recover, emphasizing the need for resilient healthcare systems.
Area of Science:
- Oncology
- Public Health
- Healthcare Management
Background:
- COVID-19 pandemic significantly disrupted global gastric cancer care pathways.
- The pandemic exposed healthcare system weaknesses while spurring innovation.
Purpose of the Study:
- To review the impact of COVID-19 on gastric cancer epidemiology, diagnosis, treatment, and care recovery.
- To propose a model for oncologic resilience and future crisis preparedness.
Main Methods:
- Narrative review with structured literature search (PubMed/MEDLINE, Scopus, Web of Science).
- Synthesis of observational studies, registry analyses, and meta-analyses.
- PRISMA-style flow diagram for study selection.
Main Results:
- Significant reduction in endoscopy volumes (up to 80%) causing diagnostic backlogs and advanced-stage diagnoses.
- Disruptions in surgery, chemotherapy, radiotherapy, and molecular testing impacted outcomes.
- Telemedicine, vaccination, and adaptive triage facilitated partial service recovery with geographical variations.
Conclusions:
- COVID-19 redefined gastric cancer care, highlighting epidemiological, diagnostic, and therapeutic shifts.
- Regional disparities in care recovery were observed.
- Lessons learned include integrating digital health, flexible protocols, and international collaboration for future preparedness.

01:27Emerging Adulthood

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...

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...

01:16Gastric Motility
3.1K
Gastric motility is the coordinated contraction and relaxation of stomach muscles that convert ingested food into chyme, a semi-liquid substance ready for further digestion in the intestines. The process begins with the vagus nerve inducing the relaxation of the smooth muscles in the fundus and body of the stomach, allowing these regions to expand and accommodate up to approximately 1.5 liters of food and liquid.

01:16Gastric Emptying
3.6K
Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...

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)...

01:26Gastric Phase of Digestion
3.3K
The gastric phase of digestion begins as soon as food enters the stomach. The incoming food bolus triggers neural and hormonal mechanisms, which last approximately 3 to 4 hours. During this phase, the stomach undergoes significant changes to prepare the food for further digestion and absorption.
When food enters the stomach, it stretches the stomach walls and activates stretch receptors. This triggers local reflexes of the enteric nervous system, mediated through the myenteric plexus. These...
