Patients with trochanteric hip fractures and pre-existing osteoarthritis can be treated with nailing osteosynthesis without significant decrease in functional status.

Purpose: Functional outcome in patients after trochanteric fracture fixation with pre-existing radiographic osteoarthritis (OA) is unclear. Analyzing their function and independence, before and after fracture, could optimize their treatment and decrease the socioeconomic burden in this particular group.

Methods: The influence of pre-existing radiographic hip OA on functional outcome was retrospectively analyzed with a cohort of patients undergoing proximal femoral nailing for trochanteric fracture.

[Portraits of everyday activities at Manguinhos].

This text reconstructs everyday routines at the Oswaldo Cruz Institute in the early twentieth century based on statements from staff at that time. As Antonil wrote in 1711, "Slaves are the hands and feet of the sugar-mill owner." The researchers' assistants fulfilled a similar role in the laboratories; their work ranged from unskilled tasks to extremely delicate scientific research that today requires specialized training.

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.

[Effect of nutritional status on mortality and functional recovery in older adults with hip fracture].

Introduction: Malnutrition is a common problem in the elderly population but has not been fully studied in elderly people with hip fractures. The goal is to estimate annual mortality based on nutrition in the elderly with hip fracture and compare motor functionality.

Material And Methods: Retrospective cohort of patients over 65 years of age with hip fracture included in the Institutional Register of The Elderly with Hip Fracture of a University Hospital, between July 2014 and July 2018.

Leishmaniases of the New World from a historical and global perspective, from the 1930s to the 1960s.

The first autochthonous cases of cutaneous and mucocutaneous leishmaniasis in the Americas were described in 1909, but visceral leishmaniasis only erupted as a public health problem in the region in 1934. Today Brazil is the country with the most cases of American tegumentary leishmaniasis, and alongside India has the highest incidence of visceral leishmaniasis. Knowledge production and efforts to control these diseases have mobilized health professionals, government agencies and institutions, international agencies, and rural and urban populations.

Survival and functionality in the elderly over 85 years of age with hip fracture.

Background: There is a tendency for the aging population to fracture their hips. Our aim was to compare survival and functionality at one year, among elderly and very elderly patients with hip fracture.

Material And Methods: A prospective cohort of patients included in the Institutional Registry of Elderly Patients with Hip Fracture between 2014 and 2017.

Zika and Aedes aegypti: new and old challenges.

Infection with the zika virus had a great impact not only on pregnant women and newborns, but also on public health, on popular ideas about Aedes aegypti and with respect to women's social rights. The objective of this paper is to identify this impact and the historical, social and health changes of the disease and the legacy of the zika virus. Interventions by researchers from different specialties foster conditions for more comprehensive investigations into future epidemic threats in Brazil and Latin America.

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.

[The dissemination of scientific knowledge, social networks and historians creating new histories: an interview with Bruno Leal].

The interview with historian and journalist Bruno Leal deals with the creation of the Café História blog and the relationship between the internet, communications and the work of historians. His blog has become an important channel to promote historical material, with bibliographical references, helpful information about films, scientific events and videos related to this area. The interviewee stressed the importance of actions that combine communications with history, made criticisms of the current training given to historians and affirmed the need for curricular reform that enables new ways of producing and disseminating historical knowledge.

[Considerations on the Sistema Único de Saúde in the twenty-first century: an interview with Lígia Bahia].

This interview with Lígia Bahia explores evaluations of the first 25 years of Brazil's Sistema Único de Saúde (SUS) and analyzes the project's progress, impasses, and missteps. Bahia is critical of both tendencies currently found within SUS: the one that sees the system as aimed at equity and the other posing equality as its goal. She criticizes the ambivalence that various spheres of government have displayed in their decisions regarding large corporate groups and private health insurance plans, which conflict with the ideas of SUS.

Malaria and quinine resistance: a medical and scientific issue between Brazil and Germany (1907-19).

This article addresses the discussion about quinine-resistant malaria plasmodium in the early decades of the twentieth century. Observed by Arthur Neiva in Rio de Janeiro in 1907, the biological and social resistance of malaria sufferers to preventive and curative treatment with quinine was corroborated three years later by Oswaldo Cruz during the construction of the Madeira-Mamoré Railway in the Brazilian Amazon. Likewise in 1910, ailing German workers were transferred from Brazil to Hamburg's Institute for Maritime and Tropical Diseases, where quinine resistance was confirmed by Bernard Nocht and Heinrich Werner.

How Brazil joined the quest for a yellow fever vaccine. Interview by Claudia Jurberg and Julia D'Aloisio.

Brazil recently announced an agreement between its Bio-Manguinhos vaccine unit and two US companies to research and develop a new yellow fever vaccine. Claudia Jurberg and Julia D'Aloisio talk to Jaime Benchimol about the controversial history of the development of the vaccine that benefits millions of people today.
