[Epidemiology of patients with hepatocellular carcinoma in a University hospital].

Hepatocellular carcinoma is the most common primary liver tumor, with 905 677 diagnosed cases and 830 180 deaths, in 2020 worldwide. In Argentina, it accounts for the 9th cause of death for cancer in men and the 10th in women. Unlike other highly-prevalent tumors, scientific evidence for most therapeutic options is limited mainly to small cohorts and retrospective studies.

[Thromboprophylaxis in hospitalized patients: implementation of a multifacetical program].

Venous thromboembolic disease is the most common preventable cause of hospital death. Despite the existence of evidence of the usefulness of thromboprophylaxis and recommendations, adherence by physicians to them is highly variable, and frequently suboptimal. The objective was to evaluate the change in the adequacy of thromboprophylaxis before and after an intervention on thromboprophylaxis with multifaceted strategies for physicians.

In-Hospital Mortality and Glycemic Control in Patients with Hospital Hyperglycemia.

Stress-induced hyperglycemia is a phenomenon that occurs typically in patients hospitalized for acute disease and resolves spontaneously after regression of the acute illness. However, it can also occur in diabetes patients, a fact that is sometimes overlooked. It is thus important to make a proper diabetes diagnosis if hospitalized patients with episodes of hyperglycemia with and without diabetes are studied.

Morphologic Variations in the Circle of Willis as a Risk Factor for Aneurysm Rupture in the Anterior and Posterior Communicating Arteries.

Background: Intracranial aneurysms are acquired abnormal vascular dilations. The most dangerous complication of a cerebral aneurysm is its rupture, with a high rate of mortality. This study aimed to determine whether there is an association between anatomic variations in the circle of Willis and ruptured aneurysms in the anterior and posterior communicating arteries.

Impact of anticoagulants in elderly patients who suffer a hip fracture. Should we have a different approach?

Introduction: Hip fracture in the elderly is a frequent problem. Chronic treatment with anticoagulants is common in these patients, and may delay surgery.

Objectives: To compare time to surgery, hospital stay, in-hospital and 90 days complications between anticoagulated (A) and non-anticoagulated (NA) groups.

Baseline Functional Status and One-year Mortality After Hospital Admission in Elderly Patients: a prospective cohort study.

Introduction: Hospitalization represents a major factor that may precipitate the loss of functional status and the cascade into dependence. The main objective of our study was to determine the effect of functional status measured before hospital admission on survival at one year after hospitalization in elderly patients.

Methods: Prospective cohort study of adult patients (over 65 years of age) admitted to either the general ward or intensive Care units (ICU) of a tertiary teaching hospital in Buenos Aires, Argentina.

Association between non-attendance to outpatient clinics and emergency department consultations, hospitalizations and mortality in a Health Maintenance Organization.

Background: Non-attendance to scheduled medical appointments in outpatient clinics is a problem that affects patient health and health-care systems.

Objective: Evaluate association of non-attendance to scheduled appointments in outpatient clinics and Emergency Department (ED) visits, hospitalizations and mortality.

Methods: Retrospective cohort study of outpatients enrolled in 2015 to 2016 in the Hospital Italiano de Buenos Aires HMO with over five scheduled appointments.

Causes of appointment attendance, nonattendance, and cancellation in outpatient consultations at a university hospital.

Background: Nonattendance to scheduled appointments in outpatient clinics is a frequent problem in ambulatory medicine with an impact on health systems and patients' health. The characterization of nonattendance is fundamental for the design of appropriate strategies for its management.

Aims: To identify causes of nonattendance of scheduled ambulatory medical appointments by adult patients.

Analysis of Postoperative Complications in Spinal Surgery, Hospital Length of Stay, and Unplanned Readmission: Application of Dindo-Clavien Classification to Spine Surgery.

Study Design: Retrospective study. Level of evidence III.

Objective: Postoperative complications in spine surgery are associated with increased morbidity, hospital length of stay, and health care costs.

Risk factors and outcomes of pyogenic liver abscess in adult liver recipients: a matched case-control study.

Background: Adult liver recipients (ALR) differ from the general population with pyogenic liver abscess (PLA) as they exhibit: reconstructed biliary anatomy, recurrent hospitalizations, poor clinical condition and are subjected to immunosuppression. The aim of this study was to identify risk factors associated with PLA in ALR and to analyze the management experience of these patients.

Methods: Between 1996 and 2016, 879 adult patients underwent liver transplantation (LT), 26 of whom developed PLA.

[Analysis of Crowding in an Adult Emergency Department of a tertiary university hospital].

Background: Crowding in Emergency Departments (ED), results from the imbalance between the simultaneous demand for health care and the ability of the system to respond. The NEDOCS scale (National Emergency Department Crowding Scale) measures the degree of crowding in an ED.

Aim: To describe ED Crowding characteristics, using the NEDOCS scale, in an Argentinean hospital.

[Associated factors with the presence of secondary neoplastic cells in the cerebrospinal fluid of patients with suspected carcinomatous meningitis].

Background: Improvement in oncologic therapy has increased survival in oncologic patients. There has been a concomitant increase in the incidence of secondary meningeal involvement. Early diagnosis is mandatory.

Institutional Registry of Elderly Patients With Hip Fracture in a Community-Based Tertiary Care Hospital in Argentina (RIAFC).

Background: A clinical registry encompasses a selective set of rigorously collected and stored clinical data focused on a specific condition. Hip fracture is a common complication of osteoporosis in elderly patients. Hip fracture substantially increases the risk of death and major morbidity in the elderly patients.

[Cross-cultural validation and telephonic reliability of modified "VIDA" questionnaire].

Instrumental activities scales allow the assessment of the functional status of the elderly; however, those currently used have gender bias and insufficient cross-cultural validation. The main objectives of this study were to perform the cross-cultural validation of the modified "VIDA: Daily living of the elderly questionnaire", created in Spain, into the Spanish spoken language in the City of Buenos Aires, and to evaluate its telephonic reliability. The secondary objective was to assess the concurrent validity of the modified VIDA questionnaire with the Lawton and Brody scale.
