Expert consensus: Profiling and management of advanced or metastatic epithelial ovarian cancer.

Introduction and objective: The approach to patients with advanced or metastatic high-grade epithelial ovarian cancer (EOC) has evolved over time with the advent of new therapies and multimodal strategies. The objective of this consensus of experts is to generate national recommendations for the profiling and management of advanced or metastatic high-grade OEC, defined as stages III and IV of the “The International Federation of Gynecology and Obstetrics (FIGO) classification at the time of diagnosis to base on the literature review that included international evidence-based clinical practice guidelines (CPG). Material and methods: Eleven panelists (oncologists and gynecological oncologists) answered 8 questions about the profiling and management of advanced or metastatic ovarian epithelial carcinoma.

Inflammatory blood cells and ratios at remission for psychosis relapse prediction: A three-year follow-up of a cohort of first episodes of schizophrenia.

Background: The clinical course following a first episode of schizophrenia (FES) is often characterized by recurrent relapses, resulting in unfavorable clinical and functional outcomes. Inflammatory dysregulation has been implicated in relapse risk; however, the predictive value of inflammatory blood cells in clinically remitted patients after a FES has not been previously explored.

Methods: In this study, we closely monitored 111 patients in remission after a FES until relapse or a three-year follow-up endpoint.

Impact of vaccination against COVID-19 on patients with cancer in ACHOC-C19 study: Real world evidence from one Latin American country.

To define the impact of vaccination against COVID-19 in preventing the risk of complications associated with the infection in a cohort of patients with cancer in Colombia. An analytical observational cohort study, based on national registry of patients with cancer and COVID 19 infection ACHOC-C19, was done.

Clinical Outcomes and Prognostic Factors of Patients With Early Malignant Melanoma in One Latin American Country: Results of the Epidemiological Registry of Malignant Melanoma in Colombia Study.

To describe the population with early malignant melanoma, we performed a cohort study on the basis of the Epidemiological Registry of Malignant Melanoma in Colombia-Asociacion Colombiana de Hematologia y Oncologia. From January 2011 until December 2021, 759 patients were included; the average age was 66 years, 57% were women, acral lentiginous histology was found in 27.8% of patients, and the median follow-up was 36.

Relapse, cognitive reserve, and their relationship with cognition in first episode schizophrenia: a 3-year follow-up study.

Schizophrenia is frequently characterized by the presence of multiple relapses. Cognitive impairments are core features of schizophrenia. Cognitive reserve (CR) is the ability of the brain to compensate for damage caused by pathologies such as psychotic illness.

Structural covariance predictors of clinical improvement at 2-year follow-up in first-episode psychosis.

The relationship between structural brain alterations and prediction of clinical improvement in first-episode psychosis (FEP) has been scarcely studied. We investigated whether structural covariance, a well-established approach to identify abnormal patterns of volumetric correlation across distant brain regions, which allows incorporating network-level information to structural assessments, is associated with longitudinal clinical course. We assessed a sample of 74 individuals from a multicenter study.

Nisin and Nisin Probiotic Disrupt Oral Pathogenic Biofilms and Restore Their Microbiome Composition towards Healthy Control Levels in a Peri-Implantitis Setting.

Peri-implantitis is characterized by chronic inflammation of the peri-implant supporting tissues that progressively and irreversibly leads to bone loss and, consequently, implant loss. Similar to periodontal disease, oral dysbiosis is thought to be a driver of peri-implantitis. However, managing peri-implantitis with traditional treatment methods, such as nonsurgical debridement or surgery, is not always successful.

Peripheral Neural Sheath Breast Sarcoma: Case Report and Literature Review.

Primary sarcomas of the breast are heterogeneous neoplasms derived from the non-epithelial elements of the mammary gland. Malignant peripheral nerve sheath tumors comprise 5-10% of all malignant soft tissue sarcomas. Its heterogeneity and low incidence (1 in 100,000) limit the performance of prospective studies.

Liver injury after SARS-CoV-2 vaccination: Features of immune-mediated hepatitis, role of corticosteroid therapy and outcome.

Background And Aims: A few case reports of autoimmune hepatitis-like liver injury have been reported after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination. We evaluated clinical features, treatment response and outcomes of liver injury following SARS-CoV-2 vaccination in a large case series.

Approach And Results: We collected data from cases in 18 countries.

Clinical and treatment predictors of relapse during a three-year follow-up of a cohort of first episodes of schizophrenia.

Relapses are frequent in the first years following a first episode of schizophrenia (FES), being associated with a higher risk of developing a chronic psychotic disorder, and poor clinical and functional outcomes. The identification and intervention over factors associated with relapses in these early phases are timely and relevant. In this study, 119 patients in remission after a FES were closely followed over three years.

The prevention of relapses in first episodes of schizophrenia: The 2EPs Project, background, rationale and study design.

Up to 80% of first-episode psychosis patients suffer a relapse within five years of the remission. Relapse should be an important focus of prevention given the potential harm to the patient and family. It threatens to disrupt their psychosocial recovery, increases the risk of resistance to treatment and has been associated with greater direct and indirect costs for society.

Impact of COVID-19 Infection on Patients with Cancer: Experience in a Latin American Country: The ACHOCC-19 Study.

Introduction: The ACHOCC-19 study was performed to characterize COVID-19 infection in a Colombian oncological population.

Methodology: Analytical cohort study of patients with cancer and COVID-19 infection in Colombia. From April 1 to October 31, 2020.

Comparison of different prognostic scores for patients with cirrhosis hospitalized with SARS-CoV-2 infection.

Introduction And Objectives: Viral infections have been described to increase the risk of decompensation in patients with cirrhosis. We aimed to determine the effect of SARS-CoV-2 infection on outcome of hospitalized patients with cirrhosis and to compare the performance of different prognostic models for predicting mortality.

Patients: We performed a prospective cohort study including 2211 hospitalized patients with confirmed SARS-CoV-2 infection from April 15, 2020 through October 1, 2020 in 38 Hospitals from 11 Latin American countries.

Drug-induced liver injury: A management position paper from the Latin American Association for Study of the liver.

Idiosyncratic drug-induced liver injury (DILI) caused by xenobiotics (drugs, herbals and dietary supplements) is an uncommon cause of liver disease presenting with a wide range of phenotypes and disease severity, acute hepatitis mimicking viral hepatitis to autoimmune hepatitis, steatosis, fibrosis or rare chronic vascular syndromes. Disease severity ranges from asymptomatic liver test abnormalities to acute liver failure. DILI has been traditionally classified in predictable or intrinsic (dose-related) or unpredictable (not dose-related) mechanisms.

Prospective Latin American cohort evaluating outcomes of patients with COVID-19 and abnormal liver tests on admission.

Materials & Methods: We performed a prospective cohort study including 1611 hospitalized patients with confirmed SARS-CoV-2 infection from April 15, 2020 through July 31, 2020 in 38 different Hospitals from 11 Latin American countries.

Infrared analysis of hair dyeing and bleaching history.

Forensic examination of hair is commonly performed to trace its origin and make a connection between a suspect and a crime scene. Such examination is based on subjective microscopic analysis of hair. During the last decade, several spectroscopic approaches have been proposed to make forensic analysis of hair more robust and reliable.

A Latin American survey on demographic aspects of hospitalized, decompensated cirrhotic patients and the resources for their management.

Introduction & Objectives: Liver cirrhosis is a major cause of mortality worldwide. Adequate diagnosis and treatment of decompensating events requires of both medical skills and updated technical resources. The objectives of this study were to search the demographic profile of hospitalized cirrhotic patients in a group of Latin American hospitals and the availability of expertise/facilities for the diagnosis and therapy of decompensation episodes.

Liver injury after methylprednisolone pulses: A disputable cause of hepatotoxicity. A case series and literature review.

Background And Objectives: Corticosteroids are often empirically used to treat idiosyncratic hepatotoxicity with severe features. Interestingly, intravenous methylprednisolone (MP) is increasingly being recognized as being responsible for liver injury. We aimed to characterize MP-induced liver injury by analyzing demographical, clinical, laboratory and outcome data of three MP-induced hepatotoxicity cases and compared this information with that of previously published cases.

Alcohol-related liver disease: Clinical practice guidelines by the Latin American Association for the Study of the Liver (ALEH).

Alcohol-related liver disease (ALD) is a major cause of advanced chronic liver disease in Latin-America, although data on prevalence is limited. Public health policies aimed at reducing the alarming prevalence of alcohol use disorder in Latin-America should be implemented. ALD comprises a clinical-pathological spectrum that ranges from steatosis, steatohepatitis to advanced forms such as alcoholic hepatitis (AH), cirrhosis and hepatocellular carcinoma.

Cognitive Reserve Assessment Scale in Health (CRASH): Its Validity and Reliability.

(1) Background: The cognitive reserve (CR) concept has not been precisely defined in severe mental disorders and has been estimated using heterogeneous methods. This study aims to investigate and develop the psychometric properties of the Cognitive Reserve Assessment Scale in Health (CRASH), an instrument designed to measure CR in people with severe mental illness; (2) Methods: 100 patients with severe mental illness (non-affective psychoses and affective disorders) and 66 healthy controls were included. The internal consistency and convergent validity of CRASH were assessed.

Is cognitive impairment associated with antipsychotic dose and anticholinergic equivalent loads in first-episode psychosis?

Background: Cognitive deficits are a core feature of early stages in schizophrenia. However, the extent to which antipsychotic (AP) have a deleterious effect on cognitive performance remains under debate. We aim to investigate whether anticholinergic loadings and dose of AP drugs in first episode of psychosis (FEP) in advanced phase of remission are associated with cognitive impairment and the differences between premorbid intellectual quotient (IQ) subgroups.
