Objective

To analyze the features of preventable adverse events (AEs) in hospitals inpatient in the state of Rio de Janeiro, in Brazil, in order to identify elements to serve as a substrate for priority actions aimed at improving patient safety.

Methods

Analysis of data from a baseline retrospective cohort study to assess the incidence of AEs in a sample of records in three teaching hospitals in the State of Rio de Janeiro to describe the features of preventable AEs.

Results

In a sample of 1,103 patients, were identified 65 preventable AEs of 56 patients who suffered preventable AEs. The healthcare associated infections (HAI) accounted for 24.6% of preventable AEs; surgical complications and/or anesthetic, 20.0%; damages arising from delay or failure in diagnosis and/or treatment, 18.4%; pressure ulcers, 18.4%; damage from complications of venipuncture, 7.7%; damage due to falls, 6.2%; damage as a result of the use of drugs, 4.6%. The preventable AEs were responsible for additional 373 days of hospital stay.

Conclusion

The HAI is the major preventable AE, as observed in other developing countries. Despite the limitations of the study, the characterization of preventable AEs indicates that known and effective actions available to reduce HAI, such as hand hygiene, to prevent pressure ulcers, to encourage adherence to protocol and clinical guidelines and to create continuing education programs for health professionals, should compose the list of priorities of hospital managers and health professionals involved in the care of hospitalized patients.

C-reactive protein (CRP) is an acute-phase protein whose requests have been growing exponentially in several countries, including Brazil. In this study, the use of CRP in several clinical situations was reviewed by a group of physicians comprised by specialists in internal medicine, medical emergencies, intensive care, screening, and laboratory medicine, aiming to analyze the applicable literature and to propose guidelines for a more rational use of this laboratory test. The result was the creation of flowcharts guiding CRP request, adjusted to four different healthcare environments, namely, intensive care units, emergency room, wards, and outpatient clinics. These flowcharts, as well as a more detailed discussion on several clinical recommendations for the test, are presented in this study.

This study aimed to establish the safety of chemotherapy use in pregnant women with breast cancer, and to find possible effects in the fetus. A search of MEDLINE/PubMed, LILACS, SciELO, Cochrane, UpToDate, and Google Scholar databases was performed to identify publications., 86 articles published from 2001 to 2012 were retrieved and evaluated by two readers in accordance predetermined exclusion and inclusion criteria; 39 articles were selected. All the chemotherapy drugs used to treat breast cancer during pregnancy belonged to class D, and consisted of 5-fluorouracil (F), doxorubicin (A) or epirubicin (E) and cyclophosphamide (C), or the combination doxorubicin and cyclophosphamide (AC), a safe regimen when used after the first trimester of pregnancy. Few studies evaluated the use of taxanes (T), such as docetaxel (D) and paclitaxel (P), with no increase in the occurrence of fetal defects and other maternal complications when used in the second and third trimesters of pregnancy. The use of trastuzumab in pregnant women is associated with oligohydramnios and anhydramnios; thus, it is not recommended during pregnancy. As almost all studies were observational and retrospective, new prospective studies on the subject are needed.

Objective

To characterize the participatory and democratic creation of the Brazilian guidelines for biorepositories and biobanks of human biological material with the purpose of research based on the ethical principles of human dignity, autonomy, beneficence, justice, and precaution.

Methods

An interdisciplinary work group was constituted to prepare the document, considering the following criteria: experience in biobank operation, regional representation, type of stored biological material, and bioethics specialists. Members of the National Health Surveillance Agency (Agência Nacional de Vigilância Sanitária – Anvisa), also participated due to their regulatory competence. Members from the National Commission on Ethics in Research (Comissão Nacional de Ética em Pesquisa – Conep) participated as the social control organization.

Results

The document, based on ethical, legal, and technical guidelines, presents the concepts, activities, purposes, and differences between biorepositories and biobanks; forms of consent on the part of the subject; in addition to other aspects permeated by concerns regarding the appropriate use of information. The Brazilian guidelines for biorepository and biobank of human biological material with the purpose of research contains 39 articles, which are distributed in five chapters.

Conclusion

The importance of legislation arises from the ethical concern, considering morals and taking into account the legal aspects, which translate into a document that does not end in itself. The dynamics of science always leads to changes in paradigms, which can go beyond the existing laws.

Objective

The occurrence of psychiatric comorbidity among individuals with crack or inhalant dependence is frequently observed. The objective of this study was to investigate anxiety symptoms among crack cocaine and inhalant users in southern Brazil.

Methods

The study investigated two groups of volunteers of equal size (n = 50): one group consisted of crack cocaine users, and the othergroup consisted of inhalant users. Research volunteers completed the Portuguese versions of the State-Trait Anxiety Inventory (STAI), Hamilton Anxiety Rating Scale (HAM-A), and Self-Report Questionnaire (SRQ).

Results

Both crack and inhalant users experience significant symptoms of anxiety. Inhalant users presented significantly more anxiety symptoms than crack users according to the HAM-A questionnaire only. In contrast to the results of the HAM-A, the STAI failed to demonstrate a significant difference between the two groups of substance users. SRQscores revealed that crack and inhalants users had significant degrees of morbidity.

Conclusion

A significant difference regarding anxiety symptomatology, especially state anxiety, was observed among inhalant and crack users. Anxiety and overall mental psychopathology were significantly correlated in this sample. The results indicate that screening initiatives to detect anxiety and additional psychiatric comorbidities among crack and inhalant users are feasible and relevant.
