- Abstract
Sexual violence is ubiquitous in the history of human relationships, with the victim being perceived as responsible for their own misfortune. This phenomenon is labelled secondary victimization and is manifested in blaming, minimizing the suffering, and avoiding the victim. This article presents evidence of the validity of a scale that measures individual differences in these three types of secondary victimization of rape victims. In Study 1, we developed the scale items and analyzed their content validity. In Study 2, we carried out an exploratory analysis of its factorial structure and verified the set-up of the items in three theoretically predicted factors (blaming, minimizing the suffering, and avoiding the victim), which had convergent validity with the Rape Myth Acceptance Scale, and discriminant validity with the Big Five Personality Traits, in addition to having concurrent validity with the Belief in a Just World Scale (BJWS). In Study 3, we confirmed this tri-factor structure using confirmatory analysis. In Study 4, we analyzed the predictive validity of the Secondary Victimization Scale (SVS), proposing the hypothesis that secondary victimization mediates the effect of BJWS on the participants' behavior towards a rape victim. The summary of the results shows consistent evidence of the SVS's validity.

- Abstract
Professional development is the vital process in the workplace that comprises the growth and maturation of knowledge, skills, and attitudes arising from formal and informal learning at work throughout one's life. The goal of this research was to present validity evidence and accuracy of the Professional Development Short Scale (PDSS) for different occupational categories. The research was conducted using four cross-sectional questionnaire surveys with convenience samples of different occupational categories ( N = 2,547) in 41 cities throughout Brazil and Angola. The first study aimed to explore the factorial structure and internal consistency of the PDSS. The second study aimed to evaluate the cross-cultural validity and measurement invariance of the scale. The third study was to assess concurrent validity and predictive validity. The fourth study was to assess the test-retest reliability. The results indicated a one-factor structure, with six items for both countries' datasets. This research pointed out the validity of the PDSS as regards its convergence-discriminant pattern with the General Self-Efficacy and Job Self-Efficacy Scales, and also, the relationship of the PDSS with relevant constructs (Bases of Power/leadership styles, In-role performance, Job Satisfaction, and Career Promotion). In this study, we provide psychometric validity of the Professional Development Short Scale to offer it as a resource to measure the construct and allow researchers to apply it in research models easily integrated to other constructs. We covered several different incremental approaches to ensure the scale validity. Besides showing temporal stability to ensure it can be applied from time to time, as one dynamic construct should, we also indicated that social desirability did not influence the measurement of the PDSS. Furthermore, the results indicate that the effects of the method do not generate undue confusion on the scale. Thus, the psychometric properties of the PDSS allow for recommending the use of the scale in extensive studies. This scale therefore contributes to contemporary professional development literature through the comparison of the perceptions of professional development in different professional categories and by providing organizational researchers with a tool to evaluate the effects and predictors of such construct., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Mourão, Tavares and Sandall.)

- Abstract
This study investigates why and where self-employment is related to higher levels of eudaimonic well-being. We focus on meaningfulness as an important eudaimonic process and subjective vitality as a eudaimonic well-being outcome that is central to entrepreneurs' proactivity. Building on self-determination theory, we posit that self-employment, relative to wage-employment, is a more self-determined and volitional career choice, which enhances the experience of meaningfulness at work and perceptions of work autonomy. In a multi-level study of 22,002 individuals and 16 European countries, meaningfulness at work mediates the relationship between self-employment and subjective vitality and explains this relationship better than work autonomy. We identify moderating effects of context: the societal legitimacy of entrepreneurship in a country affects the choice set of alternative career options that individuals can consider and thus shapes the experience of meaningfulness at work and work autonomy, and thereby indirectly subjective vitality. These findings expand our understanding of eudaimonic well-being, entrepreneurs' work, and the role of context in entrepreneurship and well-being research. They complement existing research on hedonic well-being of entrepreneurs and extend the scarce literature on their eudaimonic well-being., (© 2020 Elsevier Inc. All rights reserved.)

Tavares SM, Junior Wde L, and Lopes E Silva MR
- Abstract
Objective: The aim of this work was to evaluate the lymphocyte immunophenotype in an elderly population., Methods: This study enrolled 35 over 60-year-old volunteers and a control group composed of 35 young adults. The study included elderly without diseases that might affect the functioning of the immune system. These individuals were consulted by doctors and after a physical examination, laboratory tests were performed using a Beckman Coulter(®) flow cytometer. The GraphPad Prism computer program was employed for statistical analysis with the level of significance being set for p-values <0.05., Results: There is a statistically significant reduction in the number of lymphocytes (CD8(+), CD2(+) and CD3(+) cells) in the elderly compared to young adults. These low rates are explained by changes attributed to aging and may be partly responsible for the reduction in the cellular immune response, lower proliferative activity and the low cytotoxicity of lymphocytes., Conclusion: These parameters showed greater impairment of adaptive immunity in the elderly population and can therefore explain the greater fragility of the aged body to developing diseases., (Copyright © 2014 Associação Brasileira de Hematologia, Hemoterapia e Terapia Celular.

- Abstract
Objectives: The main goal of this study is to explore what is meant by "quality of care" (QoC) by both health professionals and patients. This research also intends to compare the perspectives of nurses, doctors and patients in order to understand whether these different actors share similar views on what represents QoC., Design and Methods: A qualitative study was conducted. The study consisted in 44 semi-structured individual interviews (11 doctors; 23 nurses; 10 patients) and in three focus groups (20 participants: doctors, nurses, patients). Participants were doctors, nurses and patients from several Hospitals in Portugal. Data were analysed using content analysis methodology with MaxQDA software., Results: The main content analysis' results revealed that all participants emphasize technical and interpersonal dimensions of QoC. Nevertheless, professionals stressed the availability of equipment and supplies and the conditions of health care indoor facilities. Patients focused more on their access to health services, namely the availability of health professionals, and on the health status outcome after care. In what the differences between doctors and nurses are concerned, the former tend to highlight the technical aspects of care more than the nurses, who tend to refer interpersonal aspects immediately., Conclusions: Although nowadays the importance of health care quality has become well-recognized, its definition is still complex. Given that specific aspects are more valued by certain groups than others, it is important to take in consideration all the stakeholder's perspectives when measuring QoC in order to continuously improve it in the 'real' settings., (© 2013 The British Psychological Society.)

- Abstract
Objective: To compare the efficacy of sublingual Zolpidem (5 and 10mg) to conventional oral Zolpidem (10mg)., Methods: This was an open, randomized, double-blind, double-dummy, controlled, and single center study. The study took place at the Laboratory of Clinical Neurophysiology and total number of participants was 58 volunteers completed the study whose demographics of age, gender, body mass index (BMI) were similar among everyone. Scores in Epworth, Pittsburgh, Beck and Hamilton Scales did not differ among groups. A model of transient insomnia was determined by the sleep anticipation in 120minute. Subjects were randomly divided in three groups for drug administration (5mSL; 10mgSL and 10mg oral), given in a single dose prior to polysomnography (PSG). Sleep parameters were assessed by PSG and post-sleep questionnaires., Results: A significant main treatment effect was evident considering the sleep onset latency (SOL) and persistent sleep latency (PSL). An earlier sleep onset was induced by SL Zolpidem 10mg (SOL=p<0.004; PSL=p<0.006) and SL Zolpidem 5mg (SOL=p<0.025; PSL=p<0.046) compared to oral Zolpidem 10mg. Subjects that received SL Zolpidem 10mg reported an earlier sleep onset (latency to sleep and latency until persistent sleep) when compared to subjects from other groups (p<0.005)., Conclusions: Sublingual Zolpidem, both 5 and 10mg, induced faster sleep initiation than 10mg oral Zolpidem. A subjective perception of earlier sleep onset was reported by subjects using SL 10mg., (Copyright © 2012 Elsevier B.V. All rights reserved.)

- Abstract
This manuscript contains the conclusion of the consensus meeting of the Brazilian Sleep Association with Brazilian sleep specialists on the treatment of narcolepsy based on the review of medical literature from 1980 to 2010. The manuscript objectives were to reinforce the use of agents evaluated in randomized placebo-controlled trials and to issue consensus opinions on the use of other available medications as well as to inform about safety and adverse effects of these medications. Management of narcolepsy relies on several classes of drugs, namely, stimulants for excessive sleepiness, antidepressants for cataplexy and hypnotics for disturbed nocturnal sleep. Behavioral measures are likewise valuable and universally recommended. All therapeutic trials were analyzed according to their class of evidence. Recommendations concerning the treatment of each single symptom of narcolepsy as well as general recommendations were made. Modafinil is the first-line pharmacological treatment of excessive sleepiness. Second-line choices for the treatment of excessive sleepiness are slow-release metylphenidate followed by mazindol. The first-line treatments of cataplexy are the antidepressants, reboxetine, clomipramine, venlafaxine, desvenlafaxine or high doses of selective serotonin reuptake inibitors antidepressants. As for disturbed nocturnal sleep the best option is still hypnotics. Antidepressants and hypnotics are used to treat hypnagogic hallucinations and sleep paralysis.

- Abstract
This manuscript contains the conclusion of the consensus meeting on the diagnosis of narcolepsy based on the review of Medline publications between 1980-2010. Narcolepsy is a chronic disorder with age at onset between the first and second decade of life. Essential narcolepsy symptoms are cataplexy and excessive sleepiness. Cataplexy is defined as sudden, recurrent and reversible attacks of muscle weakness triggered by emotions. Accessory narcolepsy symptoms are hypnagogic hallucinations, sleep paralysis and nocturnal fragmented sleep. The clinical diagnosis according to the International Classification of Sleep Disorders is the presence of excessive sleepiness and cataplexy. A full in-lab polysomnography followed by a multiple sleep latency test is recommended for the confirmation of the diagnosis and co-morbidities. The presence of two sleep-onset REM period naps in the multiple sleep latency test is diagnostic for cataplexy-free narcolepsy. A positive HLA-DQB1*0602 with lower than 110pg/mL level of hypocretin-1 in the cerebrospinal fluid is required for the final diagnosis of cataplexy- and sleep-onset REM period -free narcolepsy.

- Abstract
Objective: The aim of this study was to evaluate the efficacy of a cost-effective intra-oral appliance for obstructive sleep apnea syndrome built into a large teaching hospital., Materials and Methods: Out of 20 evaluated and treated patients, 14 concluded the study: eight men and six women, with a mean age of 42-46 (mean + SD) years and mean body mass index of 27.66. Inclusion criteria were mild or moderate apnea-hypopnea index (AHI) according to a polysomnographic study. All patients were treated with the monobloco intra-oral appliance. They were then submitted to a follow-up polysomnographic study after 60 days using the appliance. An orofacial clinical evaluation was carried out with the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) questionnaire and with clinical evaluation questionnaire devised by the Orofacial Pain Team before and 60 days after fitting the intra-oral appliance., Results: The AHI showed a statistically meaningful (p = 0.002) reduction from 15.53 to 7.82 events per hour, a non-statistically significant oxygen saturation increase from 83.36 to 84.86 (p = 0.09), and Epworth's sleepiness scale reduction from 9.14 to 6.36 (p = 0.001). Three patients did not show any improvement. The most common side effect during the use of the appliance/device was pain and facial discomfort (28.57%), without myofascial or temporomandibular joint pain as evaluated by the RDC/TMD questionnaire., Conclusions: The intra-oral device produced a significant reduction of the apnea-hypopnea index during the study period with the use of the monobloco intra-oral appliance. Patients did not show prior myofascial pain or 60 days after use of the intra-oral appliance.

- Abstract
The effects of haloperidol and olanzapine on polysomnographic measures made in bipolar patients during manic episodes were compared. Twelve DSM-IV mania patients were randomly assigned to receive either haloperidol (mean +/- SD final dosage: 5.8 +/- 3.8 mg) or olanzapine (mean +/- SD final dosage: 13.6 +/- 6.9 mg) in a 6-week, double-blind, randomized, controlled clinical trial. One-night polysomnographic evaluation was performed before and after the haloperidol or olanzapine treatment. Psychopathology and illness severity were rated respectively with the Young Mania Rating Scale (YMRS) and the Clinical Global Impressions - Bipolar version (CGI-BP). There was a significant improvement in the YMRS and CGI-BP scores at the end of the study for both groups. Mixed ANOVA used to compare the polysomnographic measures of both drugs demonstrated significant improvement in sleep measures with olanzapine. In the olanzapine group, statistically significant time-drug interaction effects on sleep continuity measures were observed: sleep efficiency (mean +/- SEM pre-treatment value: 6.7 +/- 20.3%; after-treatment: 85.7 +/- 10.9%), total wake time (pre-treatment: 140.0 +/- 92.5 min; after-treatment: 55.2 +/- 44.2 min), and wake time after sleep onset (pre-treatment: 109.7 +/- 70.8 min; after-treatment: 32.2 +/- 20.7 min). Conversely, improvement of polysomnographic measures was not observed for the haloperidol group (P > 0.05). These results suggest that olanzapine is more effective than haloperidol in terms of sleep-promoting effects, although olanzapine is comparatively as effective as haloperidol in treating mania. Polysomnography records should provide useful information on how manic states can be affected by psychopharmacological agents.

- Abstract
Rhythmic movement disorder, also known as jactatio capitis nocturna, is an infancy and childhood sleep-related disorder characterized by repetitive movements occurring immediately prior to sleep onset and sustained into light sleep. We report a 19-year-old man with a history of headbanging and repetitive bodyrocking since infancy, occurring on a daily basis at sleep onset. He was born a premature baby but psychomotor milestones were unremarkable. Physical and neurological diagnostic workups were unremarkable. A hospital-based sleep study showed: total sleep time: 178 min; sleep efficiency index 35.8; sleep latency 65 min; REM latency 189 min. There were no respiratory events and head movements occurred at 4/min during wakefulness, stages 1 and 2 NREM sleep. No tonic or phasic electromyographic abnormalities were recorded during REM sleep. A clinical diagnosis of rhythmic movement disorder was performed on the basis of the clinical and sleep studies data. Clonazepam (0.5 mg/day) and midazolam (15 mg/day) yielded no clinical improvement. Imipramine (10 mg/day) produced good clinical outcome. In summary, we report a RMD case with atypical clinical and therapeutical features.

- Abstract
The Epworth Sleepiness Scale (ESS) measures daytime sleepiness in adults. This paper reports the following data in 616 medical students: 1-ESS scores, 2-its correlation with the declared night sleep time, 3-comparison with ESS values obtained from Australia, 4-comparison of ESS values in a sub-population of 111 students tested early and late 1995. There were 387 males, 185 females and 4 not specified. Age = 20.16 +/- 2.23 (SD), ESS score = 10.00 +/- 3.69 (SD), declared sleep time = 7.04 +/- 1.03 (SD). ESS scores did not statistically correlate with sleep time. Average ESS score was statistically higher than in the Australian sample. Retesting of the medical students showed an increase in ESS values from March to November 1995. Sleep time difference was non-significant. Higher ESS scores in this sample seem to be related to shorter sleep time, but fatigue effects can not be ruled out.

- Abstract
1. Dose-equivalence studies of zopiclone and triazolam were carried out. 2. Zopiclone (6.25, 8.75 and 11.25 mg), triazolam (0.1875, 0.375 and 0.5 mg) and placebo were given in the morning to 14 healthy male volunteers aged 20-25 years under double-blind conditions according to an incomplete block design. Each patient received three of the seven possible treatments at intervals of at least 1 week. Subjects were evaluated using physiological measures, rating scales and memory tasks before and 1.5 and 4.5 h after drug administration. 3. The sedative and amnestic effects of zopiclone were qualitatively similar to those of triazolam, with the highest dose of each having the greatest effect. 4. On the basis of the digit symbol substitution test, 10 mg of zopiclone is equivalent to 0.5 mg of triazolam. Methodological problems of the experimental design of dose-equivalence studies are discussed.

- Abstract
Few data on chronic hepatitis B (CHB) have been published in our country, despite the fact that it is responsible for more than 50% of all types of chronic hepatitis. From 1968 to 1988, 164 patients were attended with the diagnosis of CHB, from whom 136 (82.9%) were male. Only 11 (8.1%) admitted homosexual behavior. Twenty six out of 39 (66.7%) health professionals were medical doctors; among them 12 (46.2%) were surgeons. The mode of transmission was unknown in 55% of the cases, but vertical and sexual transmissions were also frequent. Commercial gammaglobulin, used with prophylactic purpose, was probably responsible for eight cases between 1972 and 1975. The most frequent forms of CH were chronic active hepatitis (CAH) and liver cirrhosis (LC): 72 or 43.9% and 53 or 32.3%, respectively. The predominance of HBeAg (66.4%) was observed in all forms of CHB. Repeated biopsies showed that chronic lobular hepatitis (CLH) and chronic persistent hepatitis (CPH) may occasionally progress to CAH. This form may persist as such for some years or progress to cirrhosis. In a few cases the evolution to CPH was observed. In the long term follow-up of our patients, the appearance of hepatocellular carcinoma was observed in 8 (4.9%).
