Predictive equations in determining resting energy expenditure in patients with head and neck cancer receiving home enteral nutrition.

Objective: It is important to cover energy targets among patients with head and neck cancer (HNC) to minimize weight and skeletal muscles loss. This study aimed to assess the agreement between indirect calorimetry (IC) and predictive equations for determining resting energy expenditures (REE) in HNC patients receiving home enteral nutrition (HEN).

Research Methods And Procedures: Patients included in the study had to be diagnosed with HNC, be adults, have artificial access to the digestive tract, and participate in HEN.

Synergistic effects of calcium channel blockers and renin-angiotensin inhibitors with gemcitabine-based chemotherapy on the survival of patients with pancreatic cancer.

Purpose: Pancreatic cancer remains a significant public health challenge, with poor long-term outcomes due to the lack of effective treatment options. Repurposing commonly used clinical drugs, such as ACE inhibitors, ARBs, CCBs, and metformin, may enhance the efficacy of chemotherapy and offer a promising therapeutic strategy for improving patient outcomes.

Methods: A retrospective analysis of concomitant treatment with ACE-Is, ARBs, CCBs, and metformin alongside gemcitabine chemotherapy in patients with pancreatic cancer was conducted.

Current Approaches for the Curative-Intent Surgical Treatment of Pancreatic Ductal Adenocarcinoma.

Radical resection is the only curative treatment for pancreatic cancer. However, only up to 20% of patients are considered eligible for surgical resection at the time of diagnosis. Although upfront surgery followed by adjuvant chemotherapy has become the gold standard of treatment for resectable pancreatic cancer there are numerous ongoing trials aiming to compare the clinical outcomes of various surgical strategies (e.

Recommendations for modern perioperative care for elective surgery: consensus of panel of exerts.

Introduction: Correct surgical technique and perioperative care are two factors that can reduce the number of complications, improve treatment outcomes and shorten the length of hospital stay. The introduction of enhanced recovery protocols has changed the approach to patient care in some centers. However, there are significant differences among centers, and in some the standard of care has remained unchanged.

Simultaneous surgical treatment of hepatocellular carcinoma with tumor thrombus in the inferior vena cava and ischemic heart disease own research and literature review.

<b> Introduction:</b> Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related death worldwide. Tumor penetration into the inferior vena cava/right atrium is rare, as it occurs only in 34% of HCC patients. There are no clear guidelines for the management of this stage of disease.

The complication rate, but not the mortality rate, lower after percutaneous endoscopic gastrostomy than after open surgical gastrostomy: comparison of two methods in a high volume group of patients.

Introduction: Percutaneous endoscopic gastrostomy (PEG) has become the primary procedure for long-term enteral nutrition of most, but not all patients with dysphagia. Still in some patients gastrostomy may only be performed with open surgical technique (SG). Finally, in some patients due to relative contraindications to both methods, surgeons have to choose one of them.

The importance of proper use of oral nutritional supplements in oncological patients undergoing surgery.

<b>Introduction:</b> There are many natural approaches that may improve the nutritional status in malnourished patients. Increased consumption of natural food is a more physiological, attractive, and available form of nutritional therapy of patients than medical nutrition. However, in specific clinical situations, oral nutritional supplements (ONS) may constitute a good support of nutritional management in malnourished cancer patients.

The Relationship between Nutritional Status and Body Composition with Clinical Parameters, Tumor Stage, CA19-9, CEA Levels in Patients with Pancreatic and Periampullary Tumors.

Recent studies have obtained inadequate data on the association between nutritional status, body composition, clinical parameters and tumor stage in patients withpancreatic and periampullary tumors. The purpose of this study was to assess the relationship between nutritional status (NS), body composition (BC) and selected clinical parameters in patients with pancreatic and periampullary cancer, as well as describe the differences between resection and non-resection groups. This is a prospective study of 76 patients with pancreatic and periampullary tumors.

Clinical guidelines for the management of gastrointestinal fistula - developed by experts of the Polish Surgical Society.

Background: Gastrointestinal fistula is one of the most difficult problems in gastrointestinal surgery. It is associated with high morbidity and mortality, numerous complications, prolonged hospitalization, and high cost of treatment.

Aim: This project aimed to develop recommendations for the treatment of gastrointestinal fistulas, based on evidence-based medicine and best clinical practice to reduce treatment-related mortality and morbidity.

Brain derived neurotrophic factor declines after complete curative resection in gastrointestinal cancer.

Background: Brain derived neurotrophic factor (BDNF) is a neurotrophin involved in neural and metabolic diseases, but it is also one of the crucial factors in cancer development and metastases. In the current study, we investigated serum BDNF concentrations in patients that underwent surgical treatment for colorectal cancer or pancreatic cancer.

Methods: Serum BDNF concentrations were measured with standard enzyme-linked immunosorbent assays, before and on the third day after the operation, in 50 consecutive patients with colorectal cancer and 25 patients with pancreatic cancer (tumours in the head of pancreas).

Kidney stones are common in patients with short-bowel syndrome receiving long-term parenteral nutrition: A predictive model for urolithiasis.

Background: In short-bowel syndrome (SBS) treated with parenteral nutrition (PN), multiple complications can occur. The etiology of kidney stones may be linked to the underlying disease thrombosis, surgical complications, complications of therapy for cancer, Crohn's disease, metabolic abnormalities resulting from morphological and functional changes in the gastrointestinal tract, and to treatment used. We analyzed all these parameters in a large cohort of patients receiving home PN (HPN), to define the incidence of stones and groups of patients particularly at risk of stone formation.

Effects of Sexual Function, Social Media Use, and Self-Efficacy on Quality of Life Among Home Parenteral Nutrition Patients.

Background: Quality of life (QOL) of home parenteral nutrition (HPN) patients is a critical issue for functioning and survival. This study evaluates the roles of sexual function (SF), self-efficacy (SE), and the use of social media (USM) in the QOL of HPN patients.

Materials And Methods: The study model investigates the independent variables USM and SF and the dependent variable QOL, and SE is a mediator variable between SF and USM.

MATERIAL AND METHODS This was a retrospective study of 42 patients who underwent elective surgical repair of a persistent fistula of the small intestine.

Assessment of resting energy demand and body composition in oncological patients undergoing partial resections of the liver.

Introduction: The metabolism of the body is a complicated process. The most important organ of the organism that affects the intensity of changes is the liver. An effective treatment method of primary and metastatic tumours is a partial resection of the organ.

Surgical management of the grade C pancreatic fistula after pancreatoduodenectomy.

Background: Surgical management of severe pancreatic fistula after pancreatoduodenectomy remains challenging, and carries high mortality. The aim of this retrospective study was to compare different surgical techniques used at relaparotomy for pancreatic fistula after pancreatoduodenectomy, and to identify factors predictive of failure to rescue.

Methods: A total of 43 patients after pancreatoduodenectomy developed a pancreatic fistula requiring relaparotomy.

Assessment of changes in the body composition in patients qualified for the operational treatment of the primary and metastatic liver tumors with the use of bioelectric impedance.

Introduction: Resection is an optimal way of treatment of hepatic tumors and metastasis from another organ. The operational injury may influence on patients body composition examined by bioelectrical impedance (BIA). Analysis of parameters may be helpful in identifying early changes indicating of deterioration in nutritional status.
