Pharmaceutical enhancement and medical professionals

Emerging data indicates the prevalence and increased use of pharmaceutical enhancements by young medical professionals. As pharmaceutical enhancements advance and become more readily available, it is imperative to consider their impact on medical professionals. If pharmaceutical enhancements augment a person’s neurological capacities to higher functioning levels, and in some situations having higher functioning levels of focus and concentration could improve patient care, then might medical professionals have a responsibility to enhance? In this paper, I suggest medical professionals may have a responsibility to use pharmaceutical enhancements. In some situations, having higher functioning levels of focus and concentration is conducive to providing the best possible care to a patient. In these circumstances medical professionals should use pharmaceutical cognitive enhancements. I conclude by examining the limitations and implications of this responsibility in the practice of medicine and areas for future research.     

Epidemiology of Confirmed COVID-19 Deaths in Adults,England, March–December 2020

Of the 58,186 coronavirus deaths among adults in England during March–December 2020, 77% occurred in hospitals, 93% were in patients >60 years, and 91% occurred within 28 days of positive specimen. Cumulative mortality rates were highest among persons of Black, Asian, other, or mixed ethnicities and in socioeconomically deprived areas.     

A randomised control trial of physical activity in a perceived environment on self-esteem and mood in UK adolescents

This study assessed whether exercising whilst viewing natural or built scenes affected self-esteem (SE) and mood in adolescents. Twenty-five adolescents participated in three exercise tests on consecutive days. A graded exercise test established the work rate equivalent to 50% heart rate reserve for use in subsequent constant load tests (CLTs). Participants undertook two 15-min CLTs in random order viewing scenes of either natural or built environments. Participants completed Rosenberg’s SE scale and the adolescent profile of mood states questionnaire pre- and post-exercise. There was a significant main effect for SE (F(1) = 6.10; P < 0.05) and mood (F(6) = 5.29; P < 0.001) due to exercise, but no effect of viewing different environmental scenes (P > 0.05). Short bouts of moderate physical activity can have a positive impact on SE and mood in adolescents. Future research should incorporate field studies to examine the psychological effects of contact with real environments.     

The relationship between early maladaptive schemas and interpersonal problems: A meta‐analytic review

Early maladaptive schemas (EMSs) have been hypothesized to be associated with interpersonal problems. Furthermore, a stronger contention is that EMSs impact negatively on, or cause, interpersonal problems. The aims of this meta‐analysis were (a) to assess the strength of the association between EMSs and interpersonal problems, (b) clarify which EMSs are most strongly associated with interpersonal problems, (c) examine any possible moderators on the relationship between EMSs and interpersonal problems, and (d) examine whether any empirical evidence exists supporting a causal relationship between EMSs and interpersonal problems. A comprehensive systematic literature search and meta‐analysis were conducted using the PRISMA guidelines for systematic reviews. A total of 49 empirical studies were reviewed investigating EMSs and interpersonal problems. EMSs were found to have a moderate positive association with interpersonal problems with different EMSs having small to moderate effect sizes. To date, there has been limited evidence supporting a causal effect of EMSs on interpersonal problems. Possible limitations and avenues for future research were discussed.     

Smallpox Inoculation (Variolation) in East Africa with Special Reference to the Practice Among the Boran and Gabra of Northern Kenya

Smallpox inoculation (variolation) was widely reported in sub-Sahara Africa before, during, and after the colonial era. The infective smallpox materials and techniques used, as well as the anatomical sites for inoculation, varied widely among different ethnic groups. The practice among the Boran and Gabra pastoralists of northern Kenya resembled that which was prevalent in a number of areas of Ethiopia. This is not surprising as the Boran also live in southern Ethiopia, and Gabra herdsmen frequently cross the border into this region. The Boran and Gabra technique for smallpox inoculation consisted of taking infective material from the vesicles or pustules of those with active smallpox, and scraping it into the skin on the dorsum of the lower forearm. Although the intent was to cause a local reaction and at most a mild form of smallpox, severe cases of the disease not infrequently resulted. Also, variolated individuals were capable of infecting others with smallpox, thereby augmenting outbreaks and sustaining them. The limited known reports of smallpox inoculation among the Boran and Gabra are presented in this communication. The expansion of vaccination with effective heat stable vaccines, the development of medical and public health infrastructures, and educational programs all contributed to the eventual disappearance of the practice among the Boran and Gabra.     

The brain in acute on chronic liver failure

Acute-on-chronic liver failure (ACLF) is a newly defined clinical entity with significant morbidity and mortality (~40–90 % at 1 year dependent on need for organ support at presentation). It defines a presentation with acute severe liver injury, often with multiorgan dysfunction, on a background of previously known or unknown cirrhosis. In its severest form, it is almost indistinguishable from acute liver failure, as similarly in around 5 % may rapidly progress to intracranial hypertension and cerebral oedema culminating in coma and/or death. Our understanding of such cerebral sequelae is currently limited to clinical observation, though our knowledge base is rapidly expanding since recent consensus clinical definition and guidance. Moreover, there are now animal models of ACLF and imaging modalities to better characterize events in the brain that occur with ACLF. However, as yet there has been little in the way of interventional study of this condition which are much needed. In this review we dissect existing clinical and experimental data to better characterise the manifestations of ACLF on the brain and allow for the development of targeted therapy as currently the plethora of existing interventions were designed to treat either the effects of cirrhosis or acute liver injury independently.
