Nursing Ethical Principles II01:27

Nursing Ethical Principles II

922
Ethical principles are essential in guiding nurses to fulfill their responsibilities, focusing on the quality of nursing care and decision-making. These principles, including autonomy, beneficence, non-maleficence, justice, and fidelity, shape the ethical framework within healthcare settings.
Consider the following scenario, which illustrates how these principles are applied in the care of Mr. John, a fifty-year-old teacher diagnosed with metastatic liver cancer.
Initially, Mr. John's...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

4.9K
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...

Gallbladder01:17

Gallbladder

400
The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins...

Acute Pancreatitis II: Clinical Manifestations and Management01:30

Acute Pancreatitis II: Clinical Manifestations and Management

93
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Diseases of the Liver and Gallbladder

476
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Area of Science:

  • Surgical Oncology
  • Gastrointestinal Oncology
  • Clinical Evidence

Background:

  • Gallbladder cancer is rare, with limited high-level evidence guiding patient care.
  • Optimal treatment strategies for resectable gallbladder adenocarcinoma remain under investigation.

Purpose of the Study:

  • To evaluate the survival benefits of different treatment modalities for gallbladder adenocarcinoma.
  • To identify prognostic factors and develop a predictive tool for patient outcomes.

Main Methods:

  • A National Cancer Database (NCDB) cohort study included 8484 patients with resected gallbladder adenocarcinoma (Stage IB-IVA) from 2004-2018.
  • Survival analysis was performed comparing outcomes for cholecystectomy alone versus surgery beyond cholecystectomy, and the impact of adjuvant therapies.

Main Results:

  • Median survival was 29.8 months. Surgery beyond cholecystectomy significantly improved survival across all studied stages (IB, II, III/IVA).
  • Chemoradiotherapy demonstrated a survival benefit for Stage II and III/IVA disease. Adjuvant chemotherapy improved survival in Stage III/IVA but showed no benefit and a trend toward harm in Stage IB.
  • A predictive nomogram was developed based on these findings.

Conclusions:

  • Surgical resection beyond simple cholecystectomy offers a survival advantage for all stages of gallbladder adenocarcinoma.
  • Adjuvant chemotherapy is beneficial for Stage III/IVA disease, and chemoradiotherapy benefits Stage II and higher, guiding treatment selection for advanced gallbladder cancer.
