Background: The aetiology of Testicular Cancer (TC) is still unknown to researchers but many of the associated risk factors have been identified. These include family history, age, racial origin, cryptorchidism, urogenital malformations, testicular atrophy, and infertility. Given the lack of scientific data on the causes of the disease, it has been asserted in previous studies that the promotion of awareness and early detection are prerequisites to mitigating risks of metastasis as well as improving survival. This study is to assess the awareness, practice, and intention to practice testicular self-examination among professional working males in Accra. Methods: A quantitative cross-sectional design with a structured research instrument was used to collect data from respondants. The purposive and convenience sampling techniques were used to collect data from 300 men at Accra in Ghana. The study was conducted at two (2) Universities and a Senior High school at Accra in Ghana. The data was then analysed using descriptive statistics, logistic regression, multiple linear regression, and structural equation modeling. Results: From the study findings, 37% of male participants rated their knowledge of testicular self-examination and related symptoms as good, 28% of participants practised testicular self-examination monthly, while 65% of respondents expressed their intention to practice monthly testicular self-examination. The findings from logistic regression demonstrated that level of education, age, and marital status of participants had a significant influence on testicular self-examination. Additionally, the multiple linear regression results revealed knowledge and self-efficacy significantly predict testicular self-examination intention. The path coefficient results from the structural equation model are consistent with results from the regression models. Conclusion: This research is the first to investigate testicular self-examination among men in Ghana. The findings revealed awareness and practice of TSE are low among participants. Therefore, the research findings would improve the expertise of physicians and nurses in providing counsel, intervention, and support for patients at risk of testicular cancer. 展开更多

Reflection is a fundamental skill of health-care professionals and plays an important role in ensuring the quality of care in health-care practice. It is believed that undertaking reflection in practice can help nurses develop an awareness of a sense of personal power and agency, cultivate their critical thinking ability and help them promote their professional development. However, reflection has not been introduced widely as a nursing curriculum in China, and literature shows that some clinical nurses lack critical thinking skills and critical reflective practice skills by reason of not receiving systematic education on reflection when they were at nursing college.Therefore, we present a series of seven articles focused on prevalent and interesting practice-based events to reflect on in this special issue. The main aim is to disseminate reflective methodology and techniques and present examples of reflective writing for nurses.It is expected that these articles will help to lead Chinese nurses to adopt critical emancipatory reflective processes to bring about transformative actions. 展开更多

Objective: Reflection is viewed as the most significant skill and should be advocated for lifelong learning. In order to grasp the process of reflection and embrace the reflective skill, one of the authors of this paper reflects on a practice-based issue in relation to the communication between doctors and nurses, to gain new understanding and thus improve the authors' clinical practice.Methods: Smyth's framework with four stages is utilized as an ideal framework to guide the author's reflection on the practice-based issue to free the author from her entrenched assumptions and the oppressive forces that limit her practice.Results: The espoused and enacted theory, together with the critical reflection theory, are used to explore the values and beliefs that essentially govern the author's practice and how these are distinct from the author's worldviews. Following this, critical emancipatory reflection is undertaken to explore the dominant power structures within the author's workplace. Furthermore, given the hegemonic and chaotic working context of this issue, hegemony and symbolic interaction theory are applied to unearth the various hidden constraining and oppressive forces. Additionally, socialization theory is utilized to help the author achieve professional identity.Conclusions: Reconstructing the practice-based issue empowers the author to realize that in the future, she should act as a reflective practitioner, creating a daily habit, staying alert to practice, seeing things freshly, finding support systems, improving communication skills, conducting reflective research, and reifying reflective practice. Ultimately, the author will be sufficiently equipped to be able to transform her practice and change its outcomes. 展开更多

AIMThe survey ascertains perceptions and describes current practice of clinicians regarding medication non-adherence in patients with Inflammatory Bowel Disease. METHODSGastroenterologists, trainees and inflammatory bowel disease (IBD) specialist nurses from the United Kingdom were invited to a web based survey collecting data on clinician demographics, patient volume and level of interest in IBD. Respondents were asked to estimate non-adherence levels and report use of screening tools and interventions to improve adherence. RESULTSNon-adherence was seen as an infrequent problem by 57% of 98 respondents. Levels of non-adherence were estimated lower than evidence suggests by 29% for mesalazine (5ASA), 26% for immunomodulators (IMM) and 21% for biologics (BIOL). Respondents reporting non-adherence as a frequent problem were more likely to report adherence levels in line with evidence (5ASA P P = 0.012; BIOL P = 0.015). While 80% regarded screening as important only 25% screen regularly (40% of these with validated assessment tools). Respondents stated forgetfulness, beliefs about necessity of medication and not immediately apparent benefits as the main reasons for non-adherence. Patient counselling on benefits and risks of medication was a commonly used intervention. CONCLUSIONClinicians treating IBD patients frequently underestimate non-adherence and use of validated screening tools is infrequent. Most respondents identified the main factors associated with non-adherence in line with evidence and often counselled patients accordingly. Professional education should focus more on non-adherence practice to avoid adverse treatment outcomes associated with non-adherence. 展开更多

Objective: Reflection is considered to be one of the important ways to learn from one's experience, and one should be encouraged to apply the skill of reflection in lifelong learning. The author used the critical emancipatory reflection theory to reflect on a practice issue,which was related to the relationship between doctors and nurses, and tries to become a lifelong reflective practitioner in clinical work.Methods: Smyth's reflective framework, which includes the steps describe, inform, confront, and reconstruct, will be used in this article to help the author to understand the process of reflection and improve the skill of reflection. Utilizing Smyth's reflective framework to reflect on an issue in practice allows the author to break the routine way of thinking and learn from experience, as well as providing a higher quality of service for patients.Results: The theory of emancipatory reflection along with the critical reflection theory will be used to determine the beliefs and values that rule the author's action and derive how these are distinct from what the author is supposed to achieve. Besides, critical emancipatory reflection theory will be used to discover the dominant power structures in clinical practice; symbolic interaction and hegemony will be utilized to discover the factors that prevent the author from achieving the desired goals; socialization theory will be applied to facilitate the author in improving the professional identity.Conclusions: Using the critical emancipatory reflection on the issue in practice helps the author to find out the constraints in practice,bridge the espoused value and enacted value, and thereafter undertake transformative changes in practice. Eventually, the author can improve the skill of critical emancipatory reflection and become a lifelong reflective practitioner, and the quality of clinical practice can be improved as a result. 展开更多

Background: The aim of the study was to evaluate the knowledge, attitude and practices on child adoption among infertile women in Douala (Cameroon). Methods: It was a prospective descriptive study of six months duration at the General Hospital and the Dawn Medical Foundation Clinic. Patients of the gynecologic unit presenting with infertility were included. A questioner was administer to each patient with the following variables: Age, marital status, profession, level of education, past gynecologic history, number of children, type and the duration of infertility. Their knowledge, attitude and practice toward child adoption were investigated. Data collected was analyzed using the statistical software EPI-INFO 6.04 and R. p value < 0.05 was considered to be statistically significant. Results: Among the 300 women included, 269 (89.7%) had already heard about adoption, 62.1% through the media. Seventeen percent knew who to meet in order to adopt a child in Cameroon. Two hundred and thirty patients (76.7%) were in favor of adoption but 48.7% of them didn’t want to adopt a child. One percent of patient had adopted a child. The attitude towards adoption was significantly influenced by the duration of infertility of more than 10 years (p = 0.0014). Among women who have at least one child 9.4% wanted adoption against 21.4% who did not want adoption (p = 0.0305). Among women aged between 25 and 30 years, 28.2% wanted to adopt a child against 79.1% who did not want it (p = 0.000). Eighty five percent of women who had secondary infertility did not want to adopt against 44.7% who wanted it (p = 0.0003). Conclusion: The level of knowledge is high in educated patient. However, many women don’t know the right procedure and the structures in charge of adoption. Their attitude is favorable but the practice of adoption remains low. 展开更多

Background: Parkinson’s disease (PD) is a progressive neurodegenerative disease that occurs as a result of loss of dopaminergic neurons from the substantia nigra. Rotigotine is a non-ergolinic dopamine agonist available as a silicone-based transdermal patch for the treatment of PD. In the European Union, rotigotine transdermal patch is indicated for use as monotherapy in early idiopathic PD, or in combination with levodopa through the disease course to the late stages where motor complications with levodopa become an issue. Objective: To investigate the safety and tolerability of transdermal rotigotine, in patients with PD being treated during routine clinical practice for 2 years. Results: 114 patients were enrolled, and evaluated for adverse events over a 24-month period. Adverse events occurred in 39 patients (34.21%). 23 patients (20.17%) reported application site reactions (dermatitis, erythema, itching), and 16 (14.03%) had systemic adverse events. Sleep disorders were the most common problem;the others were hallucinations, depression, dizziness, and syncope. No patient experienced dyskinesia. Adverse events necessitated the discontinuation of rotigotine for application site reactions in fourteen patients (12.28%) and 11 patients (9.64%);reasons for discontinuation were systemic adverse events. Conclusion: Rotigotine is safe and well tolerated when used to treat PD in routine clinical practice. 展开更多

John Farrell Easmon practiced private medicine that in 1897 affected his work as the chief medical officer. The Secretary of State for the Colonies Joseph Chamberlain investigated the complaints of medical officers and fashioned the policy of the West African Medical Staff in 1902. During the Great Depression, the West African Medical Staff and Staff Pay shaped how African medical officers and European women medical doctors earned salaries as colonial government workers. Percy Selwyn-Clarke the deputy director of health service employed European women medical doctors in preventive health at infant and child welfare clinics. In 1935, health visitor Christian challenged the government for paying European woman medical doctor Nora Vane-Percy £10 to treat destitute African women and children at the Christiansborg infant welfare clinic. 展开更多

It is hoped that this will lead to lower rates of nerve injury. The objective of this study was to quantify the use of monitoring technology in current clinical practice. Method: An electronic survey was distributed to 376 registered fellows of the Australian Society of Head and Neck Surgery. Results: One-hundred and twenty-five responses were obtained. The majority of respondents report using monitoring at least some of the time during thyroid, parotid, and mastoid surgery (80%, 87%, and 73% respectively). Predictors of use include experience with intraoperative monitoring during training, and high caseloads in parotid surgery. Practice setting did not predict use. Conclusion: Despite equivocal evidence that intraoperative nerve monitoring is associated with a reduction in nerve injuries, this study demonstrates that the technology is widely used amongst otolaryngologists. 展开更多
