Burnout among physicians has a prevalence rate exceeding 50%. The radiology department is not immune to the burnout epidemic. Understanding and addressing burnout among radiologists has been a subject of recent interest. Thus, our study aims to systematically review studies reporting the prevalence of burnout in physicians in the radiology department while providing an overview of the factors associated with burnout among radiologists. The search was conducted from inception until November 13th, 2022, in PubMed, Embase, Education Resources Information Center, PsycINFO, and psycArticles. Studies reporting the prevalence of burnout or any subdimensions among radiology physicians, including residents, fellows, consultants, and attendings, were included. Data on study characteristics and estimates of burnout syndrome or any of its subdimensions were collected and summarized. After screening 6379 studies, 23 studies from seven countries were eligible. The number of participants ranged from 26 to 460 (median, 162; interquartile range, 91–264). In all, 18 studies (78.3%) employed a form of the Maslach Burnout Inventory. In comparison, four studies (17.4%) used the Stanford Professional Fulfillment Index, and one study (4.3%) used a single-item measure derived from the Zero Burnout Program survey. Overall burnout prevalence estimates were reported by 14 studies (60.9%) and varied from 33% to 88%. High burnout prevalence estimates were reported by only five studies (21.7%) and ranged from 5% to 62%. Emotional exhaustion and depersonalization prevalence estimates were reported by 16 studies (69.6%) and ranged from 11%−100% and 4%−97%, respectively. Furthermore, 15 studies (65.2%) reported low personal accomplishment prevalence, ranging from 14.7% to 84%. There were at least seven definitions for overall burnout and high burnout among the included studies, and there was high heterogeneity among the cutoff scores used for the burnout subdimensions. Burnout in radiology is increasing globally, with prevalence estimates reaching 88% and 62% for overall and high burnout, respectively. A myriad of factors has been identified as contributing to the increased prevalence. Our data demonstrated significant variability in burnout prevalence estimates among radiologists and major disparities in burnout criteria, instrument tools, and study quality.

Depressive, anxiety, and stress symptoms are prevalent in patients with inflammatory bowel disease (IBD) and may negatively influence the disease course and quality of life. The study aimed to assess the relationship between psychological factors and patients’ quality of life (QoL). A cross-sectional study with the use of a structured questionnaire among 38 patients with Crohn’s disease and 30 with ulcerative colitis was conducted. The inflammatory bowel disease questionnaire (IBDQ-32) was used to evaluate the patients’ quality of life, and the Depression, Anxiety, Stress Scale (DASS21) was used to evaluate these psychological factors. Pearson descriptive statistics and multiple regression analyses were performed. According to the findings of the multiple regression analysis, depressive, anxiety, and stress symptoms were negatively associated with quality of life. Participants with higher scores of anxiety had inferior QoL in intestinal symptoms (p=0.013) and in systemic symptoms (p=0.013), with higher scores of depression had inferior QoL in emotional function (p<0.001), and higher scores of stress had inferior QoL in the domain of social support (p=0.002). Psychological symptoms of emotional disorders appear to be associated with lower quality of life in IBD patients. This study examined levels of depression, anxiety, and stress in Greek patients with IBD, which were associated with lower levels of their quality of life. Interventions to improve QoL in patients with IBD should consider the effect of psychological symptoms.

In the past three decades, a huge body of evidence through various research studies conducted on animal models, has demonstrated that the macrophages are centralized of all the leukocytes involved in diseases and, particularly, their role in non-infectious diseases has been studied extensively for which they have also been referred to as the "double-edged swords". The most versatile of all immunocytes, macrophages play a key role in health and diseases. Various experimental models have demonstrated the conventional paradigms such as the M1/M2 dichotomy, which is not as obvious and presents a complex characterization of the macrophages in the disease immunology. In human diseases, this M1-M2 continuum shows a complex web of mechanisms, which are majorly divided into the pro-inflammatory roles (derived mainly by the cytokines: IL-1, IL-6, IL-12, IL-23, and tumor necrosis factor) and anti-inflammatory roles (CCl-17, CCl-22, CCL-2, transforming growth factor (TGF), and interleukin-10), which are involved in the wound healing and pathogen-suppression. The conventional division of these macrophages as M1 and M2 is derived from the opposing functions of these macrophages; where M1 is involved in the tissue damage and pro-inflammatory roles and M2 promotes cell proliferation and the resolution of inflammation. Both these pathways down-regulate each other in diseases through a plethora of enzymatic and cytokine mediators.

Engraftment syndrome (ES) is a non-infectious complication seen both in autologous and allogeneic hematopoietic stem cell transplants and is characterized by the presence of non-infectious fever, diarrhea, skin rash, pulmonary infiltration, pulmonary edema, and deranged renal and liver function tests This review will be delineating the incidence of ES, important differential diagnoses to be considered and management options. The literature search was done through various databases like PubMed, Google scholar, Cochrane library, and EMBASE. The incidence of engraftment syndrome was ranging from 8 to 50% in patients undergoing Autologous stem cell transplantation while the incidence was 10–77% in patients undergoing Allogeneic stem cell transplantation. Fever was the most commonly observed symptom of ES in both Autologous and Allogeneic stem cell transplantation while the second most frequently reported symptom was non-infectious diarrhea in patients undergoing autologous stem cell transplantation and Skin rash in patients with Allogeneic stem cell transplantation. Pro-inflammatory cytokines and immune response dysregulation were highlighted as the mechanism behind ES development. The significant difference between ES and aGVHD was observed based on cytokines, with IL-12, IL-1β, IL-6, TNF-α, and IFN-γ levels in plasma being higher in patients with ES as compared to patients with aGVHD. Intravenous methylprednisolone was used as the treatment of choice in the majority of the studies. Overall the incidence of ES was high in patients undergoing allogeneic hematopoietic stem cells transplantation. The survival in patients developing ES was less compared to those who did not develop ES. Engraftment syndrome is one of the complications following hematopoietic stem cell transplantation that need early identification, differentiation from infectious complications, and aGVHD and timely initiation of corticosteroids therapy.

Factors responsible for the failure of most development projects are multifaceted. This study focused on unearthing the causes and effects of public project failure from the perspective of project stakeholders. Sixty stakeholders working on different public projects in the Greater Accra Region of Ghana completed a questionnaire. This study found that major causes of project failure were related to corruption, payment delays, procurement processes, planning, monitoring, bureaucracy, communication, and supervision. The perceived effects of project failure included revenue loss, discouraged investment, and unemployment. Project failure increased the initial cost of projects, impacted economic growth, led to the provision of substandard infrastructure and service relocation. Other effects of project failure were loss of capacity for public projects and emotional stress experienced by project stakeholders. The government of Ghana should adopt strategies to overcome corruption, bureaucracy, and unnecessary political influence. Finally, the government should cooperate with relevant stakeholders to implement measures geared towards improving the current system for procurement, supervision, monitoring, planning, and management practices.
