Relações interpessoais no ambiente de trabalho da equipe de enfermagem: uma ação comunicativa

The current study strives to address the interpersonal relationships of the nursing team from the perspective of the communicative action, by contributing to the health work process. It aims to analyze the interpersonal relationships of the nursing team in its work environment. This is a descriptive study with a qualitative approach. Data collection wal held from interviews, guided by a script with open questions. The study was conducted at a state hospital in the city of Natal/RN/Brazil. The research subjects were the workers of the nursing team, including nurses, nursing technicians and nursing assistants, totaling 16 subjects. The capture of information was performed in April 2012. The project was approved by the Ethics Research Committee, under CEP/UFRN protocol n. º 262/11 and Certificate of Presentation for Ethical Consideration n. º 0289.0.051.000-11. The analysis was performed from the categories that emerged from the research through a dialogue with the authors studied in the theoretical framework of the Theory of communicative action , by Jürgen Habermas, as well as The changing in the world of work, by Ricardo Antunes, and Characterization of the team , by Marina Peduzzi. The outocomes point out that the interpersonal relationship of the nursing team is very troubled, with no interaction among the individuals involved in this process, among themselves and with other health professionals. We have developed a particular concept about team, which is comprised of three essential elements: multiplicity of individuals, common objective and heterogeneity. In the studied environment, it was realized the existence of grouping teams. The interpersonal relationship of the nursing can be a facilitator or an obstacle in the workplace in such a way that causes positive or negative consequences, both to the health workers, and to the sicks. In this context, the interviewees have intensified their viewpoints with regard to the weaknesses that permeate the nursing relationship, by pointing them more frequently than the strengths. The work conditions have signaled a failing situation, which is evidenced by the constant improvisation process before the lack of human and material resources, low wages, deficit in recognizing the nursing worker, and physical and emotional wear, by creating a professional exhaustion. The devaluation of the worker also became a strong factor for this study, because it was characterized a reason of job dissatisfaction, due to the lack of valuation policies, which should be prepared by the institution or, even, they are unknown by the worker itself. The worker participation in the design of these policies has emerged as a relevant factor. The poor work conditions lead the worker to a process of professional demotivation and dissatisfaction, by causing the feeling of devaluation within its work environment. Hence, it was found in this research that the lack of communication leads to situations of inadequate interpersonal relationships, which are creators of an unsuitable environment for the performance of the nursing team

Impacto do trabalho em profissionais de Saúde Mental de serviços de saúde do município de Mossoró-RN, 2012

The Psychiatric Reform has brought profound changes in assistance to people affected by mental disorders and behavior. In this context, mental health workers have played decisive roles of great impact, acting driving the process. Objective: To evaluate the impact felt by working professionals, because of the daily work with people who have psychiatric disorders. Methodology: This is a search field, a quantitative approach, sectional, descriptive and applied. Data collection occurred through the Assessment Scale Impact of Working in Mental Health Services (IMPACT-BR) applied to mental health researchers city Mossoró - RN. Results: Participants in this study 87 professionals, mostly female married, which took charge of higher education, working on a single service, working in the area for more than six years, aged between 25 and 64 years. There were a low effect of overloading the professionals surveyed. Discussion: Our results corroborate findings in other surveys conducted previously, not identifying large impact load at work among professionals of mental health teams studied. Subscales studied the highest score was observed in measuring the impact of work on team functioning. It was observed that the greater age and duration of action, reduced the emotional impact at work, suggesting that the experience enhances safety in decisions made and the possibility of greater control over the demands of work. Final Thoughts: The work presented showed that the interactive relationships between professionals and users are not the causes of greatest impact in the workplace, although it revealed overload in relation to specific aspects such as: fear of being assaulted by a patient and the feeling of physical exhaustion the end of the workday. Further investigations should be conducted on this topic in order to contribute to the implementation of psychiatric reform proposed by advances both in terms of assistance to individuals and the quality of life in the work of the professionals involved

H1 but not H2 histamine antagonist receptors mediate anxiety-related behaviors and emotional memory deficit in mice subjected to elevated plus-maze testing

This study investigated the role of H1 and H2 receptors in anxiety and the retrieval of emotional memory using a Trial 1/Trial 2 (T1/T2) protocol in an elevated plus-maze (EPM). Tests were performed on 2 consecutive days, designated T1 and T2. Before T1, the mice received intraperitoneal injections of saline (SAL), 20 mg/kg zolantidine (ZOL, an H2 receptor antagonist), or 8.0 or 16 mg/kg chlorpheniramine (CPA, an H1 receptor antagonist). After 40 min, they were subjected to the EPM test. In T2 (24 h later), each group was subdivided into two additional groups, and the animals from each group were re-injected with SAL or one of the drugs. In T1, the Student t-test showed no difference between the SAL and ZOL or 8 mg/kg CPA groups with respect to the percentages of open arm entries (%OAE) and open arm time (%OAT). However, administration of CPA at the highest dose of 16 mg/kg decreased %OAE and %OAT, but not locomotor activity, indicating anxiogenic-like behavior. Emotional memory, as revealed by a reduction in open arm exploration between the two trials, was observed in all experimental groups, indicating that ZOL and 8 mg/kg CPA did not affect emotional memory, whereas CPA at the highest dose affected acquisition and consolidation, but not retrieval of memory. Taken together, these results suggest that H1 receptor, but not H2, is implicated in anxiety-like behavior and in emotional memory acquisition and consolidation deficits in mice subjected to EPM testing.

EMOTIONAL BURDEN IN CAREGIEVERS of PATIENTS WITH OBSESSIVE-COMPULSIEVE DISORDER

The objective of this study was to evaluate the emotional burden, psychological morbidity, and level of family accommodation in caregivers of obsessive-compulsive disorder (OCD) patients, according to sociodemographic and clinical factors. Methods: Fifty Brazilian DSM-IV OCD patients and their caregivers were evaluated using the Family Accommodation Scale, the Zarit Burden Interview (ZBI), the Self-Report Questionnaire (caregivers), the Yale-Brown Obsessive-Compulsive Scale, and the Beck Depression Inventory (patients). Most caregivers (80%) were aged between 30 and 59 years and lived with the patient (88%). Results: Forty-two percent presented a common mental disorder and their mean ZBI score was 28.9. Family accommodation was moderate in 26% and severe or very severe in 24%. Caregivers' levels of psychological morbidity, accommodation, and emotional burden were associated with each other and with the severity of patient obsessive-compulsive and depressive symptoms. Conclusions: The results suggest that caregivers of OCD patients have important levels of burden and psychological morbidity and should receive orientation and support to minimize this emotional impact.

New meaning for the emotional state of the elderly, from a leisure standpoint

Continuing developments in science and technology that affect many dimensions of human life, especially those related to longevity, require responses from social policies and programmes to enable quality-of-life improvements in every sector, including leisure. To contribute to research in this area, this qualitative study sought to identify the perceptions of and meanings attached to participation in (active outdoor) leisure by a group of elderly citizens of Araras, São Paulo State, Brazil. Data were collected via questionnaires administered to a mixed-gender sample of 100 persons, aged between 60 and 80 years, after they had participated in an outdoor adventure/leisure programme. The data were subjected to thematic content analysis. The study revealed that the participants identified positive emotional effects as a result of their participation, relating to their sense of belonging to a group, to their increased quality of life and to their ability to remain physically active.

Effects of caffeine on time to exhaustion in exercise performed below and above the anaerobic threshold

Controversy still exists concerning the potential ergogenic benefit of caffeine (CAF) for exercise performance. The purpose of this study was to compare the effects of CAF ingestion on endurance performance during exercise on a bicycle ergometer at two different intensities, i.e., approximately 10% below and 10% above the anaerobic threshold (AT). Eight untrained males, non-regular consumers of CAF, participated in this study. AT, defined as the intensity (watts) corresponding to a lactate concentration of 4 mM, was determined during an incremental exercise test from rest to exhaustion on an electrically braked cycle ergometer. on the basis of these measurements, the subjects were asked to cycle until exhaustion at two different intensities, i.e., approximately 10% below and 10% above AT. Each intensity was performed twice in a double-blind randomized order by ingesting either CAF (5 mg/kg) or a placebo (PLA) 60 min prior to the test. Venous blood was analyzed for free fatty acid, glucose, and lactate, before, during, and immediately after exercise. Rating of perceived exertion and time to exhaustion were also measured during each trial. There were no differences in free fatty acids or lactate levels between CAF and PLA during and immediately after exercise for either intensity. Immediately after exercise glucose increased in the CAF trial at both intensities. Rating of perceived exertion was significantly lower (CAF = 14.1 ± 2.5 vs PLA = 16.6 ± 2.4) and time to exhaustion was significantly higher (CAF = 46.54 ± 8.05 min vs PLA = 32.42 ± 14.81 min) during exercise below AT with CAF. However, there was no effect of CAF treatment on rating of perceived exertion (CAF = 18.0 ± 2.7 vs PLA = 17.6 ± 2.3) and time to exhaustion (CAF = 18.45 ± 7.28 min vs PLA = 19.17 ± 4.37 min) during exercise above AT. We conclude that in untrained subjects caffeine can improve endurance performance during prolonged exercise performed below AT and that the decrease of perceived exertion can be involved in this process

Effect of the chronological age and sexual maturation on the time to exhaustion at maximal aerobic speed

The purposes of this study were: a) to verify the effect of chronological age and sexual maturation on the time to exhaustion at VO(2)max (t(lim)) and; b) to examine the reproducibility of t(lim) in boys aged 10-15 years. Forty boys, divided into 4 groups, in accordance to the chronological age (G10-12 and G13-15) and sexual maturation (P1-P3 and P4-P5 levels for pubic hair), performed the following tests: 1) incremental test for determination of VO(2)max and; 2) all-out exercise bout performed at VO(2)max to determine the t(lim). There was no difference of t(lim) (sec) between G10-12 and G13-15 (181.5 +/- 96.3 vs. 199 105.5). While the two measures of t(lim) were moderately related (r = 0.78), t(lim) from the second test (226.6 +/- 96.1 s) was higher than that of the first (191.3 +/- 79.2 s). We can conclude that the t(lim) is not influenced by chronological age and sexual maturation. Besides, t(lim) presents a lower reproducibility in children and adolescents.

Oxygen uptake kinetics and time to exhaustion in cycling and running: A comparison between trained and untrained subjects

The objective of the present study was to compare pulmonary gas exchange kinetics (VO 2 kinetics) and time to exhaustion (Tlim) between trained and untrained individuals during severe exercise performed on a cycle ergometer and treadmill. Eleven untrained males in running (UR) and cycling (UC), nine endurance cyclists (EC), and seven endurance runners (ER) were submitted to the following tests on separate days: (i) incremental test for determination of maximal oxygen uptake (VO 2max) and the intensity associated with the achievement of VO 2max (IVO 2max) on a mechanical braked cycle ergometer (EC and UC) and on a treadmill (ER and UR); (ii) all-out exercise bout performed at IVO 2max to determine the time to exhaustion at IVO 2max (Tlim) and the time constant of oxygen uptake kinetics (τ). The τ was significantly faster in trained group, both in cycling (EC = 28.2 ± 4.7 s; UC = 63.8 ± 25.0 s) and in running (ER = 28.5 ± 8.5 s; UR = 59.3 ± 12.0 s). Tlim of untrained was significantly lower in cycling (EC = 384.4 ± 66.6 s vs. UC; 311.1 ± 105.7 s) and higher in running (ER = 309.2 ± 176.6 s vs. UR = 439.8 ± 104.2 s). We conclude that the VO 2 kinetic response at the onset of severe exercise, carried out at the same relative intensity is sensitive to endurance training, irrespective of the exercise type. The endurance training seems to differently influence Tlim during exercise at IVO 2max in running and cycling. © 2003 Taylor & Francis Ltd.

Subjective, cardiovascular and EMG spectral recovery after lumbar extension exhaustion test

The purpose of this randomized study was to evaluate EMG spectral, subjective and cardiovascular recovery parameters after isometric lumbar extension contractions. Ten healthy women performed isometric lumbar extensions until exhaustion with 5%, 10%, 15% and 20% of maximal voluntary isometric contraction on 4 different days (random order). One baseline five second contraction was performed before the fatiguing task which was followed by eight submaximal five second extension contractions (until 20 minutes after the end of the fatiguing task) at the same intensity as the trial to evaluate muscle recovery. EMG (Median Frequency, Peak Power, Peak Power Frequency, Total Power and Zero-crossing Rate) and cardiovascular variables did not demonstrate any statistical difference between the 5-second contractions (p > 0.05) performed before and after the fatiguing task, showing a quick EMG recovery. However, the data analysis showed that the perceived effort variable had not recovered even 10 minutes after the fatigue contraction (p < 0.05). Our results represent a data basis for future comparisons and since subjective felling can affect performance, this study shows the importance of its analysis, since the subjective effort rate was not fully recovered after 10 minutes the end of the exhaustion contraction. © 2008 IOS Press.
