Assessing Nutritional Status in Gastric Cancer Patients after Total versus Subtotal Gastrectomy: Cross-Sectional Study.

Gastric cancer (GC) remains a significant global health concern, ranking as the third leading cause of cancer-related deaths. Malnutrition is common in GC patients and can negatively impact prognosis and quality of life. Understanding nutritional issues and their management is crucial for improving patient outcomes. This cross-sectional study included 51 GC patients who underwent curative surgery, either total or subtotal gastrectomy. Various nutritional assessments were conducted, including anthropometric measurements, laboratory tests, and scoring systems such as Eastern Cooperative Oncology Group/World Health Organization Performance Status (ECOG/WHO PS), Observer-Reported Dysphagia (ORD), Nutritional Risk Screening-2002 (NRS-2002), Patient-Generated Subjective Global Assessment (PG-SGA), and Simplified Nutritional Appetite Questionnaire (SNAQ). Serum carcinoembryonic antigen (CEA) levels were significantly higher in the subtotal gastrectomy group. Nutritional assessments indicated a higher risk of malnutrition in patients who underwent total gastrectomy, as evidenced by higher scores on ORD, NRS-2002, and PG-SGA. While total gastrectomy was associated with a higher risk of malnutrition, no single nutritional parameter emerged as a strong predictor of surgical approach. PG-SGA predominantly identified malnutrition, with its occurrence linked to demographic factors such as female gender and age exceeding 65 years.

Histological findings for the absorption of small and large liposomes - the basis of future drug delivery and contrast media systems.

BACKGROUND AND OBJECTIVES: The purpose of our study was to obtain and characterize carrier systems in different sizes that can affect oral absorption, since the mechanisms of liposome absorption are not yet fully understood. From stomach to the small intestine, liposomes can be gradually destroyed. Understanding the factors that affect oral absorption leads to developing safe and effective nanosystems to improve the oral delivery of therapeutics. MATERIALS AND METHODS: We determined the efficiency of the absorption of small and large liposomes at the level of gingival mucosa, heart, liver, testicles, kidneys, and lungs, using frozen-section fluorescence microscopy, on rat tissues after liposomes administration. A number of 36 male rats were divided in four groups: control groups, A and C, consisted of six rats each and did not receive liposomes; two other groups, B and D, were the experimental ones, and consisted of 12 male rats each. The animals received small liposomes (75-76 nm) and large liposomes (80-87 nm), respectively, administered either by endogastric tube or intraperitoneal injection. After 24 hours, the animals were sacrificed, and we harvested the organs. We performed frozen sections and analyzed them with fluorescence microscopy. RESULTS: The frozen sections obtained from all organs revealed a higher absorption level of small liposomes in the testicles, liver, and gum, while the large liposomes had a greater affinity for the liver, with variations dependent on the route of administration. CONCLUSIONS: Frozen-section fluorescence microscopy is a reliable technique for visualization of liposome absorption. Based on the size of these nanosystems, we revealed significant absorption for small liposomes in testicles, liver, heart, and gum, and for large liposomes mainly in the liver, compared with the control groups. The study advocates for the usage of liposomes for medical purposes, based on their absorption proprieties.

Hepatic injuries resulting from chronic alcohol abuse identified by forensics.

Alcohol intake is largely spread all over the world, although it is well-known that it causes important changes of the liver, from liver steatosis, hepatitis to liver cirrhosis. The study we performed on 93 patients deceased in suspicious circumstances and brought to the Institute of Forensic Medicine, Iasi, Romania, confirmed through the determination of Ethyl glucuronide, that these were alcohol consumers. The macroscopic analysis during necropsy highlighted the presence of alcoholic liver disease (ALD), while microscopy studies confirmed the macroscopic observations. The immunohistochemical studies showed the existence of a chronic liver inflammation, the transdifferentiation of stellate hepatic cells, the activation of Kupffer cells, important changes of the hepatic vascular network, hepatocyte necrosis, lipid loadings and the progression of liver fibrosis process.

Death-causing cardiac injuries after chronic alcohol intake identified by forensic medicine.

Ethyl alcohol is the most consumed drug, worldwide, with frequent consequences on the individual's health and lifestyle. Chronic alcoholism is a pathological state occurring after an excessive alcohol intake and may be observed in teenagers or very old individuals. The study performed by us investigated the changes caused by alcohol intake in the left ventricle myocardium in 77 bodies deceased at home under suspect circumstances and sent to the Institute of Forensic Medicine for establishing the cause of death. In all the individuals, there was determined high levels of blood Ethyl glucuronide, thus showing the alcohol intake up to 96 hours before death. The lesions present in the heart were represented by dilated cardiomyopathy, myocardial fibrosis, and myocardial infarction.
