Introduction: Respiratory therapists (RTs) faced morally distressing situations throughout the COVID-19 pandemic, including working with limited resources and facilitating video calls for families of dying patients. Moral distress is associated with a host of adverse psychological and functional outcomes (e.g. depression, anxiety, symptoms of posttraumatic stress disorder [PTSD] and functional impairment) and consideration of position departure. The purpose of this study was to understand the impact of moral distress and its associated psychological and functional outcomes on consideration to leave a clinical position among Canadian RTs during the COVID-19 pandemic., Methods: Canadian RTs (N = 213) completed an online survey between February and June 2021. Basic demographic information (e.g. age, sex, gender) and psychometrically validated measures of moral distress, depression, anxiety, stress, PTSD, dissociation, functional impairment, resilience and adverse childhood experiences were collected., Results: One in four RTs reported considering leaving their position. RTs considering leaving reported elevated levels of moral distress and adverse psychological and functional outcomes compared to RTs not considering leaving. Over half (54.5%) of those considering leaving scored above the cut-off for potential diagnosis of PTSD. Previous consideration to leave a position and having left a position in the past each significantly increased the odds of currently considering leaving, along with system-related moral distress and symptoms of PTSD, but the contribution of these latter factors was small., Conclusions: Canadian RTs considering leaving their position reported elevated levels of distress and adverse psychological and functional outcomes, yet these individual-level factors appear unlikely to be the primary factors underlying RTs' consideration to leave, because their effects were small. Further research is required to identify broader, organizational factors that may contribute to consideration of position departure among Canadian RTs., Competing Interests: MM is a Director at Cambridge Memorial Hospital, the Research Institute of St. Joseph’s Healthcare Hamilton and St. Joseph’s Healthcare Hamilton Foundation.

Introduction: Paramedics, firefighters, police officers and other public safety personnel (PSP) as well as Canadian Armed Forces (CAF) members are frequently exposed to stressors and demanding work environments. Although their specific work-related tasks may vary, a commonality between these occupations is the significant likelihood of repeated exposure to potentially psychologically traumatic events (PPTE) over the course of their careers. Due in part to these repeated exposures, CAF members and PSP are at an elevated risk of mental health concerns including posttraumatic stress disorder. The purpose of this study was to obtain a more in-depth understanding of the trauma- and non-trauma-related experiences of active or retired PSP and CAF members that may be implicated in mental health issues and resultant treatment and recovery., Methods: Study participants were recruited during inpatient treatment at a private mental health and addictions inpatient hospital in Canada. We conducted and audiotaped semistructured focus groups and transcribed the discussions. Interpretive phenomenological analysis and thematic coding generated a coding scheme from which to identify concepts and linkages in the data., Results: Analysis generated four primary themes: interpersonal relationships, personal identity, mental health toll and potential moral injury. A variety of subthemes were identified, including family dynamics, inability to trust, feelings of professional/personal betrayal, stigma within the CAF/PSP culture, increased negative emotions about self/others, and a reliance on comradery within the service., Conclusion: The information gathered is critical to understanding the perspectives of PSP and military members as the career stressors and related exposure to PPTE of these occupations are unique., Competing Interests: The authors have no conflicts of interest to disclose.

The pharmacological management of heart failure has evolved during the last decade from therapies focused on improving haemodynamics to others that modulate neurohormonal systems which are activated in the setting of left ventricular dysfunction. Despite optimal inhibition of these systems with drugs such as ACE inhibitors, beta-blockers, digoxin and, most recently, spironolactone, the mortality rate remains unacceptably high. Calcium antagonists have long been investigated for use in a variety of cardiovascular diseases, including ischaemic heart disease, hypertension, and heart failure. However, concern has arisen with regard to the use of calcium antagonists in the treatment of left ventricular dysfunction--particularly those agents with negative inotropic activity. In addition, first generation dihydropyridines have also generated concern because of their profound vasodilatory effects and the fact that they have been shown to increase noradrenaline (norepinephrine) levels and neurohormonal activity. The third generation dihydropyridine calcium antagonists appear to be more promising therapies for heart failure, given their pharmacological properties of higher vascular selectivity and their minimal effects on neurohormonal activation. Several trials have been conducted with third generation dihydropyridines and additional trials are ongoing. A new class of calcium antagonists, which blocks the T-type calcium channel, was introduced in 1998. The prototype drug, mibefradil, was rigorously tested for use in heart failure in the Mortality Assessment in Congestive Heart Failure (MACH-1) trial. It was expected that calcium antagonists blocking the T-type calcium channel would be of benefit, because of their lack of negative inotropic effects and their ability to induce regression of hypertrophy. The results of the MACH-1 trial were disappointing, and the trial was prematurely discontinued as a result of excess mortality in the mibefradil arm. The purpose of this review is to examine the evidence-based pharmacotherapeutic strategies in the management of heart failure, and to discuss current and potential roles for calcium antagonists in the therapeutic regimen.

Between January 1, 1991 and June 30, 1996, physicians performed 800 cases of tubal ligation via minilaparotomy under local anaesthesia in the Obstetrics and Gynecology clinic of the Dakar University Teaching Hospital (Senegal). There were complications in 7 (0.87%) cases (bladder and bowel injuries: 6 cases, and post operative infection: 1 case). The most frequent risk factors were: surgeon skill (lack of experience of surgeon in minilaparotomy), type of patients (obesity, previous abdominal surgery). It was concluded, proper training and experience of the surgical team is needed to minimize sterilization related complications.
