Background: Malnutrition and sarcopenia are highly prevalent in patients with head neck cancer (HNC). An accurate early diagnosis is necessary for starting nutritional support, as both are clearly associated with clinical outcomes and mortality. We aimed to evaluate the applicability and accuracy of body composition analysis using electrical bioimpedance vectorial analysis (BIVA) for diagnosing malnutrition and sarcopenia in patients with HNC cancer undergoing systemic treatment with chemotherapy or radiotherapy.

Article Synopsis
  • * A scoping review examined the existing literature regarding psychedelics and seizures, analyzing 16 human and 11 animal studies from various databases, which generally suggest that psychedelics do not increase seizure risk in healthy individuals without other drug interactions.
  • * However, the findings have limitations in external validity and caution is advised, with future research needed to explore neurobiological factors that may explain the relationship between psychedelics and seizures.

Pancreatoduodenectomy, the primary surgical strategy for managing cholangiocarcinoma, is executed via two distinct methodologies, namely minimally invasive pancreatoduodenectomy (MIPD) and open pancreatoduodenectomy (OPD). The selection between these surgical options is critical, as it directly influences patient outcomes, encompassing both short-term recovery metrics and long-term survival rates. Despite the clinical significance of these procedures, there exists a notable void in the literature regarding a comprehensive comparison of MIPD and OPD, particularly in assessing their respective efficacies and complications.

Nutritional deficiencies represent a prevalent concern among individuals with obesity, stemming from suboptimal dietary habits, chronic inflammation, and preoperative weight reduction efforts. Bariatric surgical interventions, employing either restrictive, malabsorptive or a combination of the two methods, further compound these deficiencies. Commonly observed nutritional deficits following bariatric surgeries include vitamin B, vitamin D, thiamine, folate, iron, and protein deficiencies.

Inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, is a chronic condition characterized by inflammation of the gastrointestinal tract. Its exact cause is unknown, but it's thought to result from a dysregulated immune response influenced by various factors, including changes in the intestinal microbiota, diet, lifestyle, and genetics. The gut microbiome, consisting of diverse microorganisms, plays a crucial role in maintaining physiological balance, with its disruption leading to inflammatory responses typical of IBD.

Introduction: Bioelectrical impedance analysis (BIA) serves as a method to estimate body composition. Parameters such as phase angle (PA), standardized phase angle (SPA), body mass cell (BCM), BCM index (BCMI), and fat-free mass (FFM) might significantly impact the prognosis of head and neck cancer (HNC) patients. The present study aimed to investigate whether bioelectrical parameters can be used to predict survival in the HNC population and establish the optimal cutoff points for predictive accuracy.

Lipodystrophy syndromes are rare diseases that could be of genetic or acquired origin. The main complication of lipodystrophy is the dysfunction of adipose tissue, which leads to an ectopic accumulation of triglycerides in tissues such as the liver, pancreas and skeletal muscle. This abnormal fat distribution is associated with hypertriglyceridemia, insulin resistance, liver steatosis, cardiomyopathies and chronic inflammation.

Myelofibrosis (MF) is a BCR-ABL1-negative myeloproliferative neoplasm characterized by clonal myeloproliferation, dysregulated kinase signaling, and release of abnormal cytokines. In recent years, important progress has been made in the knowledge of the molecular biology and the prognostic assessment of MF. Conventional treatment has limited impact on the patients' survival; it includes a wait-and-see approach for asymptomatic patients, erythropoiesis-stimulating agents, androgens, or immunomodulatory agents for anemia, cytoreductive drugs such as hydroxyurea for the splenomegaly and constitutional symptoms, and splenectomy or radiotherapy in selected patients.
