The Role of Psychological Adjustment in the Decision-Making Process for Voluntary Termination of Pregnancy

BACKGROUND: This study's objective was to evaluate the role of psychological adjustment in the decision-making process to have an abortion and explore individual variables that might influence this decision. METHODS: In this cross-sectional study, we sequentially enrolled 150 women who made the decision to voluntarily terminate a pregnancy in Maternity Dr. Alfredo da Costa, in Lisbon, Portugal, between September 2008 and June 2009. The instruments were the Depression, Anxiety and Stress Scale (DASS), Satisfaction with Social Support Scale (SSSS), Emotional Assessment Scale (EAS), Decision Conflict Scale (DCS), and Beliefs and Values Questionnaire (BVQ). We analyzed the data using Student's T-tests, MANOVA, ANOVA, Tukey's post-hoc tests and CATPCA. Statistically significant effects were accepted for p<0.05. RESULTS: The participants found the decision difficult and emotionally demanding, although they also identified it as a low conflict decision. The prevailing emotions were sadness, fear and stress; but despite these feelings, the participants remained psychologically adjusted in the moment they decided to have an abortion. The resolution to terminate the pregnancy was essentially shared with supportive people and it was mostly motivated by socio-economic issues. The different beliefs and values found in this sample, and their possible associations are discussed. CONCLUSION: Despite high levels of stress, the women were psychologically adjusted at the time of making the decision to terminate the pregnancy. However, opposing what has been previously reported, the women presented high levels of sadness and fear, showing that this decision was hard to make, triggering disruptive emotions.

Tilt Training Increases Vasoconstrictor Reserve in Patients with Neurocardiogenic Syncope

Neurocardiogenic syncope (NCS) is a common clinical entity resulting from an excessive reflex autonomic response, particularly during orthostatism. Treatment options are controversial and of limited effectiveness. Tilt training (TT) is a promising option to treat these patients. However, its mechanism of action and clinical impact remain unclear. OBJECTIVE: To characterize hemodynamic and autonomic responses during a TT program in patients with NCS refractory to conventional measures. METHODS: We studied 28 patients (50% male, mean age 41±14 years) without structural heart disease, with NCS documented by tilt testing. The TT program included 9 tilt sessions (3 times a week, 30 min) (60° - 6 sessions, 70° - 3 sessions), under ECG and blood pressure monitoring combined with home orthostatic self-training and 10° head-up during sleep. Systolic volume, cardiac output, total peripheral resistance, baroreflex sensitivity and heart-rate variability were computed. Patients were reassessed at 1 month and every 6 months for a maximum of 36 months (24±12 months). RESULTS: Over the course of the TT program there was a significant increase in total peripheral resistance (1485±225 vs. 1591±187 dyn·s·cm(-5), p<0.05), with a decrease in standard deviation (206±60 vs. 150±42, p<0.05). During follow-up, syncope recurred in five patients (19%), with a significant reduction in the number of episodes (4.0±3.2/patient in the 12 months before TT vs. 1.4±0.8/patient post-TT, p<0.05). CONCLUSION: In refractory NCS, TT may be an effective therapeutic option, with long-term benefits. These results appear to be due to an increase in vasoconstrictor reserve combined with a reduction in its variance.

Five-Year Review of an International Clinical Research-Training Program

The exponential increase in clinical research has profoundly changed medical sciences. Evidence that has accumulated in the past three decades from clinical trials has led to the proposal that clinical care should not be based solely on clinical expertise and patient values, and should integrate robust data from systematic research. As a consequence, clinical research has become more complex and methods have become more rigorous, and evidence is usually not easily translated into clinical practice. Therefore, the instruction of clinical research methods for scientists and clinicians must adapt to this new reality. To address this challenge, a global distance-learning clinical research-training program was developed, based on collaborative learning, the pedagogical goal of which was to develop critical thinking skills in clinical research. We describe and analyze the challenges and possible solutions of this course after 5 years of experience (2008-2012) with this program. Through evaluation by students and faculty, we identified and reviewed the following challenges of our program: 1) student engagement and motivation, 2) impact of heterogeneous audience on learning, 3) learning in large groups, 4) enhancing group learning, 5) enhancing social presence, 6) dropouts, 7) quality control, and 8) course management. We discuss these issues and potential alternatives with regard to our research and background.

Tuberculose e infecção VIH/SIDA : uma análise comparativa em Portugal continental no biénio 2008-2009

RESUMO - Introdução: Actualmente 11,3 milhões de indivíduos estão co-infectados pela Tuberculose/Vírus Imunodeficiência Humana (TB/VIH), uma das principais causas de incapacidade e morte no mundo. É determinada pela exposição dos indivíduos aos factores de risco e condições/determinantes sociais de saúde. Várias são as medidas criadas a nível nacional e internacional na luta contra TB e a infecção VIH. Objectivo: Caracterizar e comparar os casos de TB entre os indivíduos não infectados com VIH e os infectados com VIH, considerando as características sócio-demográficas, o tratamento, patologias associadas e factores de risco. Método: Estudo descritivo, quantitativo e observacional. A informação foi obtida a partir da base de dados do Sistema Nacional de Vigilância Epidemiológica da Tuberculose dos casos de TB notificados entre 1 de Janeiro de 2008 a 31 de Dezembro de 2009. Para tratamento e análise estatística (descritiva e inferencial) o programa usado foi o SPSS versão 18,0. Resultados: 12,8% dos indivíduos estavam co-infectados com TB/VIH e 87,2% não estavam co-infectados. A presença de VIH nos casos de tuberculose apresenta evidência de relação com quase todas variáveis em estudo (p<0,00) excepto a presença de insuficiência renal (p<0,307). Apresentam maior probalidade de risco da co-infecção TB/VIH os homens, a faixa etária [35;44[, os estrangeiros, os desempregados, estar em retratamento e fumar. Os indivíduos com Doença Hepática (OR= 5,238; IC95%: 3,706;7,403; ORA = 3,104; IC95%: 2,164;4,454), patologias associadas (OR=13,199; IC95%: 11,246; 15,491; ORA=21,348; IC95%:17,569; 25,940) e factores de risco (OR=3,237; IC95%: 2,968; 3,531; ORA=2,644; IC95%: 2,414; 2,985) tem maior probalidade da co-infecção TB/VIH. O ajustamento para o sexo e a idade interferiu em todas variáveis em estudo. Conclusão: Os homens, da faixa etária [35;44 [, desempregados, estrangeiros, em retratamento, fumadores apresentam maior probalidade de risco de estar co-infectado com TB/VIH.
