Inbreeding and Gallbladder Cancer Risk: Homozygosity Associations Adjusted for Indigenous American Ancestry, BMI, and Genetic Risk of Gallstone Disease.

Latin Americans have a rich genetic make-up that translates into heterogeneous fractions of the autosomal genome in runs of homozygosity (F) and heterogeneous types and proportions of indigenous American ancestry. While autozygosity has been linked to several human diseases, very little is known about the relationship between inbreeding, genetic ancestry, and cancer risk in Latin Americans. Chile has one of the highest incidences of gallbladder cancer (GBC) in the world, and we investigated the association between inbreeding, GBC, gallstone disease (GSD), and body mass index (BMI) in 4029 genetically admixed Chileans.

Multicenter analysis of the surgical management and adjuvant therapy of patients with melanoma and a positive sentinel lymph node biopsy.

Introduction: Complete lymph node dissection (CLND) was the standard practice for patients with melanoma and a positive sentinel lymph node biopsy (SLNB) until the results of 2 clinical trials published in 2016 and 2017 demonstrated that it did not improve melanoma-specific survival (MSS). However, it continues to be performed in some scenarios. No studies have ever been published on lymph node management after a positive SLNB in the routine clinical practice in our setting.

Life Fatigue: A Critical Analysis.

Introduction: In recent years, euthanasia has been decriminalized or legalized in several countries. The debate on whether to legalize such a practice is open in many places and is a topic that arouses great controversy. Euthanasia has been presented as a response to situations of advanced, incurable, or irreversible disease, or situations that cause intolerable suffering to the person.

[Utilization of Upadacitinib in the treatment of Crohn's disease: a report on two clinical cases].

Crohn's disease (CD) is a chronic, progressive inflammatory disease with complications that impact the well-being of patients. The therapeutic advances achieved in recent decades, especially through the advent of biological therapy, have allowed for a transformation in the approach and management of CD, thereby modifying the course of this disease. However, a significant number of patients do not experience a satisfactory response to these drugs or lose it during the course of the disease.

Radical cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in the treatment of peritoneal sarcomatosis: Results from a reference center and considerations based on current evidence.

Introduction: Peritoneal sarcomatosis is a rare disease, with multiple histological origins and poor overall prognosis. The option of radical cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is controversial. The results of a surgical team experienced in these procedures are analyzed and discussed based on the available evidence.

Clustering COVID-19 ARDS patients through the first days of ICU admission. An analysis of the CIBERESUCICOVID Cohort.

Background: Acute respiratory distress syndrome (ARDS) can be classified into sub-phenotypes according to different inflammatory/clinical status. Prognostic enrichment was achieved by grouping patients into hypoinflammatory or hyperinflammatory sub-phenotypes, even though the time of analysis may change the classification according to treatment response or disease evolution. We aimed to evaluate when patients can be clustered in more than 1 group, and how they may change the clustering of patients using data of baseline or day 3, and the prognosis of patients according to their evolution by changing or not the cluster.

Oxidative stress involvement in the molecular pathogenesis and progression of multiple sclerosis: a literature review.

Multiple sclerosis (MS) is an autoimmune debilitating disease of the central nervous system caused by a mosaic of interactions between genetic predisposition and environmental factors. The pathological hallmarks of MS are chronic inflammation, demyelination, and neurodegeneration. Oxidative stress, a state of imbalance between the production of reactive species and antioxidant defense mechanisms, is considered one of the key contributors in the pathophysiology of MS.

Personalised therapy in inflammatory bowel disease.

Inflammatory bowel diseases (IBD), with ulcerative colitis and Crohn's disease being their most common presentations, comprise a spectrum of diverse disease phenotypes, exhibiting variable behaviors ranging from an indolent course to aggressive phenotypes that impact quality of life of these patients. The last two decades have been marked by the development of new medications (biological therapy and novel small molecules) with diverse mechanisms of action, which have revolutionized the management of IBD, thereby enhancing the quality of life for these patients. This landscape of multiple therapeutic options underscores the need to define which medication will benefit each patient the most and at what speed it should be started.
