Background: The COVID-19 pandemic has led to a significant increase in the workload of healthcare workers that, together with the risks associated with exposure to this new virus, has a􀀀ected their mental health. Objectives: The objective of the current study was to determine the prevalence of psychopathology and burnout syndrome in healthcare workers and the predictive role of purpose in life andmoral courage in this relationship. Methods: A cross-sectional study was carried out in 115 Spanish healthcare workers. Results: Participants with burnout had higher anxiety (p = 0.001), depression (p < 0.001), post-traumatic stress (p = 0.01) and alcohol consumption (p = 0.03) levels. The di􀀀erent components of burnout (emotional fatigue and despersonalization) were associated with the occurrence of anxiety (OR = 0.31) and depression (OR = 0.26), respectively. A strong purpose in life decreased emotional fatigue (OR = −0.39) depersonalization (OR = −0.23) scores, increased personal accomplishment (OR = 0.52), subsequently reducing burnout levels (OR = −0.45). Conclusions: Purpose in life was most strongly related to decreased levels of burnout. Furthermore, an association between anxiety, depression and the components of burnout was found.

Although multiple studies have shown the role genetics plays in personality disorders and in addictions, few have studied the genetic aspects of their comorbidity. Here, we carried out a cross-sectional study in a sample comprising 303 Caucasian polydrug-consuming patients. The presence of personality disorders was evaluated using the International Personality Disorder Examination, and genes related to dopamine, serotonin and monoamine oxidase (MAO) were genotyped. A significant relationship was observed between the bp 279 DRD5 variable number of tandem repeat (VNTR) polymorphism and paranoid personality disorder ðORð95%CIÞ¼2:186 ð1:074;4:449Þ;p¼0:006Þ. The bp 182 ðORð95%CIÞ¼0:407 ð0:178;0:931Þ;p¼0:033Þ and bp 184 ðORð95%CIÞ¼0:391 ð0:188;0:813Þ;p¼0:012Þ alleles of the MAOB VNTR were also associated with antisocial personality disorder. Among patients with addictions, paranoid personality disorder should also be considered in addition to the importance of antisocial and borderline personality disorders. The higher frequency of the bp 279 DRD5 VNTR allele found in patients with paranoid personality disorder, as well as the associations between alleles of the MAOB VNTR and antisocial personality disorder, support the monoaminergic bases of these personality disorders, especially when dealing with patients with addictions.
