Mental health first aid training for Australian medical and nursing students: an evaluation study

BACKGROUND: The role and demands of studying nursing and medicine involve specific stressors that may contribute to an increased risk for mental health problems. Stigma is a barrier to help-seeking for mental health problems in nursing and medical students, making these students vulnerable to negative outcomes including higher failure rates and discontinuation of study. Mental Health First Aid (MHFA) is a potential intervention to increase the likelihood that medical and nursing students will support their peers to seek help for mental health problems. This study aimed to evaluate the effectiveness of a tailored MHFA course for nursing and medical students.

METHODS: Nursing and medical students self-selected into either a face-to-face or online tailored MHFA course. Four hundred and thirty-four nursing and medical students completed pre- and post-course surveys measuring mental health first aid intentions, mental health literacy, confidence in providing help, stigmatising attitudes and satisfaction with the course.

RESULTS: The results of the study showed that both the online and face-to-face courses improved the quality of first aid intentions towards a person experiencing depression, and increased mental health literacy and confidence in providing help. The training also decreased stigmatizing attitudes and desire for social distance from a person with depression.

CONCLUSION: Both online and face-to-face tailored MHFA courses have the potential to improve outcomes for students with mental health problems, and may benefit the students in their future professional careers.

Nocebo effects in the treatment of major depression: results from an individual study participant-level meta-analysis of the placebo arm of duloxetine clinical trials

BACKGROUND: The nocebo effect, when a harmless substance creates harmful effects in a person who takes it, is a clinically salient yet seldom studied phenomenon that may be associated with poorer treatment outcomes, perceived adverse events, and treatment discontinuation. The covert presence of nocebo responders in clinical trials may contribute to outcome variance in both placebo and active treatment arms for important primary and secondary endpoints. Nocebo effects are thought to be driven by expectancy and conditioning. METHOD: This study analyzed pooled clinical trial data in the placebo arms of controlled trials of antidepressant medications to investigate variables associated with the emergence of adverse outcomes in placebo-treated participants (N = 2,457). Specifically, we examined treatment-emergent adverse events (TEAEs) and discontinuation in placebo-treated individuals. Trials were commenced between 1993 and 2010 as studies of duloxetine versus active comparator and/or placebo. RESULTS: TEAEs were reported by 1,569 placebo-treated participants (63.9%), with 115 (4.7%) discontinuing from the studies due to TEAEs and 274 (11.2%) showing worsening of Hamilton Depression Rating Scale total score during placebo treatment. There was specifically no evidence to support the expectancy hypothesis, that reported TEAEs were influenced by adverse effects described in the clinical trials participant information and consent forms, or the conditioning hypothesis, that reported TEAEs would be influenced by adverse effect profiles of previous antidepressant medications used by these study participants. There was some evidence to suggest that people who had previously used complementary medications were more likely to report TEAEs. Variables specific to individual studies were the strongest predictors of TEAEs. DISCUSSION: In this study, TEAEs were very common among placebo-treated clinical trial participants. Unexpectedly, there was no evidence to associate TEAEs with adverse clinical outcomes, nor were the conditioning or expectancy hypotheses supported by these data. CONCLUSIONS: The nocebo effect is a common, covert, and poorly understood driver of clinical outcomes that requires further investigation.

Avaliação das pressões respiratórias máximas em crianças e adolescentes da grande Natal: elaboração de uma equação preditiva

The human respiratory system was so designed that would allow efficient ventilation, regardless of variations in the external environment that may hinder the act of breathing, such an act involves dozens of variables, among them we find the respiratory depression, which is nothing more than respiratory muscle strength. The pressures are widely used in several cases: Neuro-muscular; evolution of pulmonary dysfunction and a predictor for discontinuation of mechanical ventilation. Therefore it was proposed to carry out evaluations of these respiratory pressures for children and adolescents aged 10 to 16 years and propose a predictive equation that involves the anthropometric variables age (A, years), body mass (BM, kilograms) and height (H, meters) with maximal respiratory pressures (maximum inspiratory and expiratory pressure). Evaluations were performed in this age group of students in public and private schools of the Grande Natal , measurements were performed using the analogue manometer, were children and adolescents and their parents gave informed consent. 517 samples were taken, and 250 for males (M), 255 for females (F) and 12 were excluded according to our exclusion criteria. The sample was subdivided into three age groups (10-11, 12-13 and 14 to 16 years old). It was found through the student s t test (p ≤ 0.05) for all variables studied, children and male adolescents had higher means than females, except for the MC. For the correlation between the variables found significant correlation (p <0.05) among all the variables when analyzed as pairs except between MIP and height for females. The development of predictive equations (for p ≤ 0.05) based on three types of strategies adopted were restricted to two association between anthropometric variables isolated, resulting in: for males: MIP = -32.29 + (-2.11*A) + (-0.52*BM), MIP = 9.99 + (-0.36*BM) + (-49.40*H); MEP = 18.54 + 3.53*A + 0, 42*BM, MEP = -33.37 + 2.78*A + 52.18* H, MEP = -17.39 + 0.33*BM + 55.04*H; and, for females we find: MEP = 24.32 + 2.59 * A + 0.24*BM

Microbiota intestinal de indivíduos que sofreram acidente ocupacional com materiais biológicos e que realizaram profilaxia anti-retroviral

Avaliar a microbiota intestinal de indivíduos que sofreram acidente ocupacional com materiais biológicos e receberam anti-retrovirais foi o objetivo deste estudo. O grupo de estudo constou de 23 indivíduos com idade entre 18-45 anos, sendo 13 doadores de sangue e 10 que sofreram acidente ocupacional. Foram avaliados a microbiota intestinal, antropometria e exames laboratoriais pré, pós e 30 dias após o término da medicação. Zidovudina mais lamivudina foi utilizada em 70% dos indivíduos associado ao nelfinavir, 20% ao efavirenz e 10% ao ritonavir. As alterações nutricionais e dietéticas-laboratoriais e de microbiota intestinal foram analisadas em três momentos. M1: até dois dias do início da profilaxia; M2: no último dia da profilaxia e M3: 30 dias após o término da profilaxia. Náuseas, vômitos e diarréia estiveram presentes em 50% no segundo momento do estudo. Sobrepeso em 70%, desnutrição e eutrofia em 10%, dos indivíduos, não se modificaram durante o estudo. Transaminases, triglicérides, LDL-colesterol se elevaram no segundo momento e normalizaram 30 dias após término da medicação. Houve redução significativa dos Lactobacillus, Bifidobacterium e Bacteróides nos três momentos. Uso de anti-retrovirais provocou impacto significativo na microbiota intestinal dos indivíduos, sem recuperação em 30 dias.

Motivos do abandono do seguimento médico no cuidado a portadores de hipertensão arterial: a perspectiva do sujeito

A hipertensão arterial é um expressivo problema de saúde pública enquanto fator de risco para as doenças cardiovasculares e principal grupo de causas de mortalidade no Brasil. A baixa adesão e o abandono do tratamento estão entre os principais obstáculos às estratégias individuais de controle. Estudam-se os motivos do abandono do seguimento médico em uma coorte de pacientes em tratamento de hipertensão arterial, em serviço de atenção primária à saúde, acompanhados por um período de quatro anos. Foram realizadas entrevistas semiestruturadas com cinquenta pessoas com hipertensão que abandonaram o seguimento médico. As respostas foram analisadas mediante a técnica de análise temática de conteúdo. Os motivos relatados para o abandono do seguimento mostraram predomínio de razões ligadas ao próprio serviço de saúde - sua organização, estrutura e a relação médico-paciente - e, ainda, tratamento em outro serviço de saúde. Razões de natureza psicossocial, como a ausência de sintomas, a melhora e/ou a normalização da pressão arterial e o consumo de álcool também contribuíram para o abandono do cuidado. Estudar os motivos do abandono na perspectiva do próprio sujeito permitiu verificar a riqueza e diversidade de problemas envolvidos no cuidado requerido.

Intoxicação por metronidazol em cão - relato de caso

Metronidazole is a nitronidazolic antibiotic used in veterinary medicine to the treatment of a variety of diseases. The cause of metronidazole neurotoxicity has not been determined. We report the case of a dog, female, Teckel, five-year-old, with a history of dorsiflexion of the tail, ataxia, muscle stiffness, recumbency, vertical nystagmus, apathy and anorexia, which was being medicated for seven days with metronidazole in a dose higher than the maximum recommended, and the neurological signs began after this period. Neurological signs were consistent with central vestibular dysfunction caused by metronidazole, such as ataxia and vertical nystagmus. In addition to the neurological changes, the clinical signs of anorexia and apathy are consistent with the administration of excessive doses of the medicine. The diagnosis of metronidazole-induced toxicosis is based on the history of normal to increased doses, clinical signs and resolution after discontinuation of the drug. In general, the prognosis is good after drug withdrawal and early diagnosis. Some dogs may die and others may recover completely. The neurotoxicosis has disappeared after the suspension of the medicine and supportive treatment. Veterinarians must be aware of potential complications associated with the use of this medicine, as well as limit their chronic use or high doses for the most severe cases, and diagnose the problem as quickly as possible to institute an early treatment.

Oral bisphosphonate-related osteonecrosis of the jaws in rheumatoid arthritis patients: a critical discussion and two case reports

Background: Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a clinical condition characterized by the presence of exposed bone in the maxillofacial region. Its pathogenesis is still undetermined, but may be associated with risk factors such as rheumatoid arthritis (RA). The aim of this paper is to report two unpublished cases of BRONJ in patients with RA and to conduct a literature review of similar clinical cases with a view to describe the main issues concerning these patients, including demographic characteristics and therapeutic approaches applied.Methods: Two case reports of BRONJ involving RA patients were discussedResults: Both patients were aging female taking alendronate for more than 3 years. Lesions were detected in stage II in posterior mandible with no clear trigger agent. The treatment applied consisted of antibiotics, oral rinses with chlorhexidine, drug discontinuation and surgical procedures. Complete healing of the lesions was achieved.Conclusions: This paper brings to light the necessity for rheumatologists to be aware of the potential risk to their patients of developing BRONJ and to work together with dentists for the prevention and early detection of the lesions. Although some features seem to link RA with oral BRONJ and act as synergistic effects, more studies should be developed to support the scientific bases for this hypothesis.

Epidemiological aspects of rheumatoid arthritis patients affected by oral bisphosphonate-related osteonecrosis of the jaws

This literature review aims to evaluate the epidemiologic profile of patients with rheumatoid arthritis (RA) that developed a bisphosphonate-related osteonecrosis that affect the jaws (BRONJ), including demographic aspects, as well as clinical and therapeutic issues. A search of PUBMED/MEDLINE, Scopus, and Cochrane databases from January 2003 to September 2011 was conducted with the objective of identifying publications that contained case reports regarding oral BRONJ in RA patients. Patients with RA who develop oral BRONJ are usually women above 60 years taking steroids and long-term alendronate. Most of them have osteoporosis, and lesions, triggered by dental procedures, are usually detected at stage II in the mandible. Although there is no accepted treatment protocol, these patients seem to have better outcomes with conservative approaches that include antibiotic therapy, chlorhexidine, and drug discontinuation.

Accurate Approach in the Treatment of Oral Bisphosphonate-Related Jaw Osteonecrosis

Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is not completely understood and difficult to treat. Even though the occurrence of BRONJ is mainly related to the therapy with intravenous bisphosphonates (BPs), this article reports a case of long-term oral BP use and BRONJ occurrence. In addition, a literature review provides some additional information about BPs, BRONJ, and also a guideline for the prevention and treatment of BRONJ stages. A 79-year-old patient presented intense and persistent pain, purulent secretion, and exposed bone at the right side of the lower jaw. Thus, she was submitted to anamnesis, radiologic and tomographic examinations, and bacterial culture and sensitivity tests. These procedures were followed by surgical debridement of the bone and surrounding tissues/cyst and antibiotic prescription and histopathologic analysis of the fragments. Together, the examinations performed showed the occurrence of stage 2 BRONJ. Moreover, the antibiotic prescription, discontinuation of oral BP, and surgical procedures ensure that the patient had no more symptoms. Therefore, considering the presented case, we believe that an accurate approach is promising to diagnose and treat stage 2 BRONJ and other associated pathologic findings.

EFFECTS OF FENCAMFAMINE WITHDRAWAL IN RATS

1. The effects produced by discontinuation of long-term treatment with fencamfamine (FCF) were evaluated recording behavioral and body weight changes.2. 48 hr after withdrawal of FCF rats shelved a significant decrease in exploratory behavior when compared to saline-treated ones.3. Discontinuation of treatment with FCF resulted in a significant increase in body weight on days of drug withdrawal.4. These results suggest that FCF caused signs of withdrawal similar to other psychostimulant drugs.

Complete denture wearing and fractures among edentulous patients treated in university clinics

Objective: The prevalence of wearing and fracture of complete dentures was evaluated among edentulous patients treated in two dental schools in Brazil. Background: Acceptance and wearing of complete dentures are related to adaptive behaviour of edentulous patients. However, one reason that could interfere with the wearing dentures is their potential to fracture, which is still a common complication in denture rehabilitation practice. Material and methods: Two hundred and twenty-four edentulous patients rehabilitated with complete dentures from 2000 to 2005 in Araçatuba and Araraquara Dental School, University of State of São Paulo, were assessed in 2006 and 2007 to answer a questionnaire about wearing and fracture of their dentures. Statistical analysis were performed using Epi Info software and chi-squared test to compare maxillary and mandibular data (α = 0.05). Results: Almost 26% of the patients did not wear their dentures, and among the remainder, the majority wore the maxillary denture. About 30% of the dentures were fractured, with higher prevalence in the maxillary arch (p = 0.003). Conclusions: Discontinuation of wearing dentures was quite high, especially considering the treatment which was carried out in university clinics. Prevalence of fractures was also high, greater for the maxillary denture, and was one of the main reasons for non-wearing of complete dentures. © 2011 The Gerodontology Society and John Wiley & Sons A/S.
