Working Experience and Librarians' Knowledge of Information and Communication Technologies (ICTs) in Nigerian University Libraries

This paper discuses the influence of librarians' years of working experience and sources of acquisition of ICTs' knowledge and skills. The study is based on 169 librarians working in thirteen university libraries in the universities of six states located in the South-South zone of Nigeria. The purpose of the paper is to find out if years of working experience has an effect on librarians' sources/means of acquisition of ICT knowledge and skills. The questionnaires used were answered by two categories of librarians. Those with longer years of experience – 16 years and above and those with fewer years of working experience. It was concluded that librarians with fewer years of working experience explore means of acquiring ICTs knowledge and skills more than librarians with more years of working experience. It was recommended that librarians with longer years of working experience develop more interest in sources through which they can acquire ICT knowledge and skills.

Women's knowledge of health effects of oral contraceptives in five Brazilian cities

Background: Although acceptability of combined oral contraceptives (COCs) is widespread, patients are often unaware of the noncontraceptive benefits. Study Design: An opinion survey through telephone interview was conducted to evaluate the knowledge of 500 Brazilian women 15-45 years of age who were current users or had recently used COCs. Data were obtained on their knowledge of adverse events, the effects of COCs on health- and menstrual-related symptoms, noncontraceptive benefits and aspects related to sexual response. Results: Most of the women interviewed learned about the pill from doctors or the Internet. Other than the pill, the best-known contraceptive methods were the condom and intrauterine device. The majority of women believe that COCs do not change the risk of gynecological cancers. Most believed that they had no significant effect on sexual response. Conclusions: COCs users in Brazil lack precise information on aspects related to general health, particularly menstrual-related symptoms and noncontraceptive health benefits. (C) 2012 Elsevier Inc.

Cardiac Magnetic Resonance Imaging: What Can It Add to Our Knowledge of the Right Ventricle in Pulmonary Arterial Hypertension?

Pulmonary arterial hypertension (PAH) is a disease of the pulmonary vasculature characterized by vasoconstriction and vascular remodeling leading to a progressive increase in pulmonary vascular resistance (PVR). It is becoming increasingly recognized that it is the response of the right ventricle (RV) to the increased afterload resulting from this increase in PVR that is the most important determinant of patient outcome. A range of hemodynamic, structural, and functional measures associated with the RV have been found to have prognostic importance in PAH and, therefore, have potential value as parameters for the evaluation and follow-up of patients. If such measures are to be used clinically, there is a need for simple, reproducible, accurate, easy-to-use, and noninvasive methods to assess them. Cardiac magnetic resonance imaging (CMRI) is regarded as the "gold standard" method for assessment of the RV, the complex structure of which makes accurate assessment by 2-dimensional methods, such as echocardiography, challenging. However, the majority of data concerning the use of CMRI in PAH have come from studies evaluating a variety of different measures and using different techniques and protocols, and there is a clear need for the development of standardized methodology if CMRI is to be established in the routine assessment of patients with PAH. Should such standards be developed, it seems likely that CMRI will become an important method for the noninvasive assessment and monitoring of patients with PAH. (C) 2012 Elsevier Inc.

Awareness and knowledge of HPV, cervical cancer, and vaccines in young women after first delivery in São Paulo, Brazil - a cross-sectional study

Abstract Background The success of HPV vaccination programs will require awareness regarding HPV associated diseases and the benefits of HPV vaccination for the general population. The aim of this study was to assess the level of awareness and knowledge of human papillomavirus (HPV) infection, cervical cancer prevention, vaccines, and factors associated with HPV awareness among young women after birth of the first child. Methods This analysis is part of a cross-sectional study carried out at Hospital Maternidade Leonor Mendes de Barros, a large public maternity hospital in Sao Paulo. Primiparous women (15-24 years) who gave birth in that maternity hospital were included. A questionnaire that included questions concerning knowledge of HPV, cervical cancer, and vaccines was applied. To estimate the association of HPV awareness with selected factors, prevalence ratios (PR) were estimated using a generalized linear model (GLM). Results Three hundred and one primiparous women were included; 37% of them reported that they "had ever heard about HPV", but only 19% and 7%, respectively, knew that HPV is a sexually transmitted infection (STI) and that it can cause cervical cancer. Seventy-four percent of interviewees mentioned the preventive character of vaccines and all participants affirmed that they would accept HPV vaccination after delivery. In the multivariate analysis, only increasing age (P for trend = 0.021) and previous STI (P < 0.001) were factors independently associated with HPV awareness ("had ever heard about HPV"). Conclusions This survey indicated that knowledge about the association between HPV and cervical cancer among primiparous young women is low. Therefore, these young low-income primiparous women could benefit greatly from educational interventions to encourage primary and secondary cervical cancer prevention programs.

Contribution towards the knowledge of Rhinotragini (Coleoptera, Cerambycidae). V. Reconsideration of Rhopalessa rubroscutellaris (Tippmann, 1960)

Corrections to the revision of Rhopalessa Bates, 1873 (Clarke et al. 2011), with the transfer of two species to a new genus, Rashelapso: R. durantoni (Peñaherrera-Leiva & Tavakilian, 2004) comb. nov., and R. schmidi sp. nov. (previously considered to be conspecific with Ommata (Rhopalessa) rubroscutellaris Tippmann, 1960 by the authors). Ommata (Rhopalessa) rubroscutellaris is now considered a junior synonym of Laedorcari fulvicollis (Lacordaire, 1868).

Students' knowledge of symptoms and risk factors of potential life-threatening medical conditions

In order to assess medical students' knowledge of Basic Life Support (BLS) principles, we defined a minimal knowledge (MK) of three life-threatening medical conditions that should be universally known: cardiac arrest, heart attack and stroke, and compared the results with those of laypersons.

Assessing Nursing Assistants' Knowledge of Behavioral Approaches to Mental Health Problems

Nurse's aides are the primary caregivers in nursing homes, a major receiving site for elders with behavioral and psychiatric problems. We describe the development, psychometric properties, and utility of a brief instrument designed to assess aides' knowledge of three specific mental health problems (depression, agitation, and disorientation) and behavioral approaches to them. The instrument was administered to 191 nurse's aides and 21 clinicians with training in behavioral management and experience with older residents. The nurse's aides averaged 11 of 17 correct answers, and the clinicians averaged 15 of 17 correct answers. Implications for staff training and consultation activities in nursing homes are discussed.

Decision-making in amnesia: do advantageous decisions require conscious knowledge of previous behavioural choices?

Previous work has reported that in the Iowa gambling task (IGT) advantageous decisions may be taken before the advantageous strategy is known [Bechara, A., Damasio, H., Tranel, D., ; Damasio, A. R. (1997). Deciding advantageously before knowing the advantageous strategy. Science, 275, 1293-1295]. In order to test whether explicit memory is essential for the acquisition of a behavioural preference for advantageous choices, we measured behavioural performance and skin conductance responses (SCRs) in five patients with dense amnesia following damage to the basal forebrain and orbitofrontal cortex, six amnesic patients with damage to the medial temporal lobe or the diencephalon, and eight control subjects performing the IGT. Across 100 trials healthy participants acquired a preference for advantageous choices and generated large SCRs to high levels of punishment. In addition, their anticipatory SCRs to disadvantageous choices were larger than to advantageous choices. However, this dissociation occurred much later than the behavioural preference for advantageous alternatives. In contrast, though exhibiting discriminatory autonomic SCRs to different levels of punishment, 9 of 11 amnesic patients performed at chance and did not show differential anticipatory SCRs to advantageous and disadvantageous choices. Further, the magnitude of anticipatory SCRs did not correlate with behavioural performance. These results suggest that the acquisition of a behavioural preference--be it for advantageous or disadvantageous choices--depends on the memory of previous reinforcements encountered in the task, a capacity requiring intact explicit memory.
