A Quantum Cascade Laser (QCL) was invented in the late 90s as a promising mid-infrared light source and it has contributed to the fields of industry, military, medicine, and biology. The room temperature operation, watt-level output power, compact size, and wide tuning capability of this laser advanced the field of noninvasive blood glucose detection with the use of transmission, absorption, and photoacoustic spectroscopy. This review provides a complete overview of the recent progress and technical details of these spectroscopy techniques, using QCL as an infrared light source for detecting blood glucose concentrations in diabetic patients.Using density functional theory (DFT), we studied the formation of Stone-Wales defects in pyrene, as a prototype PAH molecule. In addition, we studied the reactivity of the defective and pristine pyrenes toward hydrogenation, a process that can occur in some regions of the interstellar medium. We found that the formation of the defect requires overcoming energies of the order of 8.4 eV, but the defective structure is stable due to the high reverse reaction barrier (approx. 6 eV). We also found that the presence of the defect decreases the sticking barrier for the first hydrogenation and promotes more stable singly and doubly hydrogenated intermediates with respect to that of the pristine pyrene. Finally, our results show that both Stone-Wales pyrene and pristine pyrenes can lead to the formation of H2 through an extraction mechanism involving H atoms attached on distal carbon atoms with energy barriers below 2 eV.Fiona Martin is a psychiatry trainee who spent 6 months volunteering in a mental health service in Uganda between her core and higher psychiatry training. In this article, she reflects upon this experience, including the challenges and rewards, and in particular the benefits to training of such an experience. © The Author 2019.Sri Lanka ranks highest in the region for human development. Despite producing the first female head of state in the world, the country has failed to achieve substantial gains in the gender inequality indices in the past decade. learn more In recent years, the proportion of females in secondary education has equalled that of males, and young women have become the majority among the university entrants. These educated young women are likely to face psychosocial distress in a patriarchal society where they would be expected to fulfil traditional gender roles. This article describes gender disparities that could affect the mental well-being of young Sri Lankan women and the need for awareness among mental health professionals in the country. © The Authors 2018.The history of psychiatry and homosexuality illuminates how stigma develops in the professions, how it is linked to cultural values and religious attitudes and how it affects patients. Homosexuality was medicalised as a disorder in the late 19th century and this led to treatments to change it. Same-gender contacts between men were decriminalised in many countries in the 1960s and 1970s, but - as recently as the 1980s - 30% of doctors in the USA did not think that gay students should be admitted to medical school and 40% would not allow gay doctors to specialise in paediatrics or psychiatry. Lesbians and gay men were effectively debarred from training in the main psychoanalytical schools in the USA and the UK. Although mainstream psychological treatments to make gay and bisexual people heterosexual fell into disrepute in the 1980s, so-called conversion or reparative treatments took their place and are still practised today. Transgender people have been the target of similar disapproval and attitudes towards them have been even slower to change than those towards lesbians and gay men. This stigma had consequences on the health, well-being and social inclusion of those who were lesbian, gay, bisexual and transgender (LGBT). This history suggests we need to examine where psychiatry and psychology are making similar mistakes today. © The Author 2019.Global mental health (GMH) work reminds us about our professional ideals and mission. GMH specialists conduct research and provide psychosocial and mental health support to populations affected by humanitarian crises around the world. This work exposes these specialists to situations with a high degree of moral ambiguity and no good solutions, where humanitarian accountability takes priority over conflicting values. Self-awareness helps to address the countertransference that confounds complex decision-making and can compromise the health and safety of all involved. The evolving role of GMH as a humanitarian actor underscores the importance of professional competencies in assuring the integrity and standards of practice. © The Author 2019.The purpose of national HIV surveillance is to track and summarize trends in newly diagnosed cases as an indicator of HIV transmission within Canada, and supports the development and evaluation of programs and policies for prevention, testing and delivery of care. Accurately capturing and interpreting trends in HIV diagnoses within national surveillance becomes complicated when there is movement of people within a country or when individuals are diagnosed with HIV prior to migrating to a new country. This has been identified as an issue in other countries, including Australia, New Zealand and Switzerland. The Public Health Agency of Canada (PHAC) recently assessed this in Canada after noting a rise in new HIV cases in Canada between 2014 to 2017. An environmental scan was conducted to better understand how new and previously diagnosed cases of HIV were recorded by and reported to PHAC from provincial and territorial (PT) public health authorities. It was discovered there was variation with respect to the repoat had been documented in Canada over the last four years. link2 In the future, national surveillance data will be calculated adopting this new common definition of a previous positive test result, in order to more accurately describe the trends in HIV transmission occurring in Canada.Background Human immunodeficiency virus (HIV) is a global public health issue, with an estimated 36.9 million people living with HIV in 2017. HIV has been reportable in Canada since 1985 and the Public Health Agency of Canada (PHAC) continues to monitor trends in new HIV diagnoses. Objective The objective of this surveillance report is to provide an overview of the epidemiology of all reported diagnoses of HIV in Canada since 1985 with a focus on 2018 overall, and by geographic location, age group, sex, and exposure category. Methods PHAC monitors HIV through the national HIV/AIDS Surveillance System, a passive, case-based system that collates nonnominal data that is voluntarily submitted by all Canadian provinces and territories. Descriptive epidemiological analyses were conducted on national data and those relating to specific populations provided by Immigration, Refugees and Citizenship Canada and the Canadian Perinatal HIV Surveillance Program. Results In 2018, a total of 2,561 HIV diagnoses were reportedgbMSM continued to account for the largest exposure category and the number and rate of reported HIV cases among women increased. PHAC will continue to work with its national partners to refine the collection, analysis and publication of national data to better understand the burden of HIV in Canada.Vaccine hesitancy (the reluctance to accept recommended vaccines) is a complex issue that poses risk communication challenges for public health authorities and clinicians. Studies have shown that providing too much evidence on vaccine safety and efficacy to those who are vaccine-hesitant has done little to stem the growth of hesitancy-related beliefs and fears. The objective of this paper is to describe good practices in developing communication materials to address vaccine hesitancy. link3 An inventory of vaccination communication materials in Canada was assessed according to the Council of Canadian Academies Expert Panel on Health Product Risk Communication Evaluation (2015). Many of the current communication products could be improved to better align with evidence-based risk communication best practices. Five best practices were identified. First, identify target audience and establish trust. Second, provide both the risks and benefits of vaccination, as most people are looking for balanced information. Third, give the facts before addressing the myths. Fourth, use visual aids. Fifth, test communication material prior to launch. Applying these best practices to current or future communication products will help vaccine providers (including physicians, nurse practitioners, pharmacists, public health professionals) to develop communication materials that are sensitive to the complex ways that people process and value information and thus more likely to optimize vaccine uptake in their communities.Background Although it is well documented that bloodborne viruses (BBVs), including human immunodeficiency virus (HIV), hepatitis C virus (HCV) and hepatitis B virus (HBV) have been transmitted from patients to healthcare workers (HCWs), there has also been reported transmission from HCWs to patients during the provision of health care. With remarkable progress in infection prevention, diagnosis tools, treatment regimens and major improvements in guideline development methodology, there was a need to develop an evidence-based guideline to replace the 1998 Canadian consensus document for managing HCWs infected with BBVs. Purpose This article summarizes the Canadian Guideline on the Prevention of Transmission of Bloodborne Viruses from Infected Healthcare Workers in Healthcare Settings. Methods A Guideline Development Task Group was established and key questions developed to inform the guideline content. Systematic reviews were conducted to evaluate the risk of HCW-to-patient transmission of HIV, HCV and HBV. Enaging HCWs infected with a BBV, with recommendations related to preventing HCW-to-patient transmission of BBVs during the provision of care.Background In April 2018, Ottawa Public Health identified a large-scale infection prevention and control (IPAC) lapse spanning 15 years related to inadequate reprocessing of reusable critical medical equipment used in a family medicine clinic. Objectives To describe the public health response to, and estimate the risk of hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) transmission from, this IPAC lapse. Methods Patients who underwent a procedure of concern (during which reusable equipment may have been used) at this clinic were identified using Ontario Health Insurance Plan data and individually notified. Testing for HBV, HCV and HIV at the Public Health Ontario Laboratory was recommended, and the odds of infection were estimated. Results Of 4,495 patients possibly exposed to improperly reprocessed equipment, 1,496 (33.3%) underwent testing within six months of notification. The prevalence of HBV, HCV and HIV infection in this group was lower than in the general Canadian population. Among patients first diagnosed with HBV after a procedure of concern, the odds of HBV transmission were not increased when the procedure occurred within seven or 28 days of another patient with a positive HBV test result (OR7 days, age-adjusted=0.59, 95% CI 0.14-2.51; OR28 days, age-adjusted=1.35, 95% CI 0.62-2.93). The odds of HCV and HIV transmission could not be estimated because no patient was diagnosed with HCV or HIV after having a procedure of concern within 28 days of another patient with a positive HCV or HIV test result. Conclusion We found no evidence of HBV, HCV or HIV transmission associated with this IPAC lapse. However, transmission cannot be ruled out conclusively because only a third of possibly exposed patients underwent testing.
