Reasoning Abilities

Arguments regarding the credibility of psychologists’ and psychiatrists’ expert testimony are commonly restricted to impressions about whether claims to special reasoning powers or capabilities are justified or not. The large, but often neglected body of research on human judgment provides a means for analyzing these claims scientifically. Systematic review shows that claims for the beneficial effects of experience and practice on judgment accuracy, the clinician's powers of data integration, the ability to utilize clinical impression, and the capacity to detect malingering have little evidence and extensive counterevidence. Caution is advised in using these claims to bolster one's credibility.

Abstract Physicians who use the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides) often serve as medical expert witnesses. In workers’ compensation cases, the expert may appear in front of a judge or hearing officer; in personal injury and other cases, the physician may testify by deposition or in court before a judge with or without a jury. This article discusses why medical expert witnesses are needed, what they do, and how they can help or hurt a case. Whether it is rendered by a judge or jury, the final opinions rely on laypersons’ understanding of medical issues. Medical expert testimony extracts from the intricacies of the medical literature those facts the trier of fact needs to understand; highlights the medical facts pertinent to decision making; and explains both these in terms that are understandable to a layperson, thereby enabling the judge or jury to render well-informed opinions. For expert witnesses, communication is everything, including nonverbal communication that critically determines if judges and, particularly, jurors believe a witness. To these ends, an expert medical witnesses should know the case; be objective; be a good teacher; state opinions clearly; testify with appropriate professional demeanor; communicate well, both verbally and nonverbally; in verbal communications, explain medical terms and procedures so listeners can understand the case; and avoid medical jargon, finding fault or blaming, becoming argumentative, or appearing arrogant.

AbstractSusceptibility to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the risk of mortality among people living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) (PLWHA) is largely unknown. PLWHA are unique due to their altered immune system from their history of chronic HIV infection and their use of antiretroviral therapy, some of which have been used experimentally to treat coronavirus disease 2019 (COVID-19). Therefore, we conducted a systematic review and meta-analysis to assess the epidemiology of SARS-COV-2/HIV coinfection and estimate associated mortality from COVID-19 (Prospero Registration ID: CRD42020187980). PubMed, SCOPUS, OVID and Cochrane Library databases, and medRxiv preprint repositories were searched from January 1, 2020, to December 12, 2020. Data were extracted from studies reporting COVID-19 attack and mortality rates in PLWHA compared to their HIV-negative counterparts. Pooled attack and mortality risks were quantified using random-effects models. We identified 22 studies that included 20,982,498 participants across North America, Africa, Europe, and Asia. The median age was 56 years, and 50% were male. HIV-positive persons had a significantly higher risk of SARS-CoV-2 infection [risk ratio (RR) 1.24, 95% CI 1.05–1.46)] and mortality from COVID-19 (RR 1.78, 95% CI 1.21–2.60) than HIV-negative individuals. The beneficial effects of tenofovir and protease-inhibitors in reducing the risk of SARS-CoV-2 infection and death from COVID-19 in PLWHA remain inconclusive. HIV remains a significant risk factor for acquiring SARS-CoV-2 infection and is associated with a higher risk of mortality from COVID-19. In support of the current Centers for Disease Control and Prevention (CDC) guidelines, persons with HIV need priority consideration for the SARS-CoV-2 vaccine.

ObjectivesPrevious studies have reported beneficial effects of perioperative music on patients’ anxiety and pain. We performed a systematic review and meta-analysis of randomised controlled trials investigating music interventions in cardiac surgery.MethodsFive electronic databases were systematically searched. Primary outcomes were patients’ postoperative anxiety and pain. Secondary outcomes were hospital length of stay, opioid use, vital parameters and time on mechanical ventilation. PRISMA guidelines were followed and PROSPERO database registration was completed (CRD42020149733). A meta-analysis was performed using random effects models and pooled standardised mean differences (SMD) with 95% confidence intervals were calculated.ResultsTwenty studies were included for qualitative analysis (1169 patients) and 16 (987 patients) for meta-analysis. The first postoperative music session was associated with significantly reduced postoperative anxiety (SMD = –0.50 (95% CI –0.67 to –0.32), p<0.01) and pain (SMD = –0.51 (95% CI –0.84 to –0.19), p<0.01). This is equal to a reduction of 4.00 points (95% CI 2.56 to 5.36) and 1.05 points (95% CI 0.67 to 1.41) on the State-Trait Anxiety Inventory and Visual Analogue Scale (VAS)/Numeric Rating Scale (NRS), respectively, for anxiety, and 1.26 points (95% CI 0.47 to 2.07) on the VAS/NRS for pain. Multiple days of music intervention reduced anxiety until 8 days postoperatively (SMD = –0.39 (95% CI –0.64 to –0.15), p<0.01).ConclusionsOffering recorded music is associated with a significant reduction in postoperative anxiety and pain in cardiac surgery. Unlike pharmacological interventions, music is without side effects so is promising in this population.

The Relationship

This article reports on empirical research conducted into the use of audiovisual links (videolinks) to take expert testimony in jury trials. Studies reveal ambivalent attitudes to court use of videolink, with most previous research focussed on its use for vulnerable witnesses and defendants. Our study finds there are issues unique to expert witnesses appearing by videolink, such as compromised ability to gesture and interact with exhibits and demonstrative tools, and reductions in availability of feedback to gauge juror understanding. Overall, the use of videolinks adds an additional cognitive load to the task of giving expert evidence. While many of these issues might be addressed through environmental or technological improvements, we argue this research has broader ramifications for expert witnesses and the courts. The use of videolinks for taking expert evidence exposes the contingent nature of expertise and the cultural scaffolding inherent in its construction. In reflecting on the implications of these findings, and on the way that reliability, credibility and expertise are defined and established in court, we suggest a more critical engagement with the relationship between content and mode of delivery by stakeholders.

According to Giles Scofield, ethicists can provide expert testimony in descriptive ethics and metaethics, but not normative ethics. Lawrence Schneiderman appears to disagree with this view, and presumably believes that it is appropriate for an expert witness in ethics to provide ethics testimony in all three areas. I draw this conclusion from several claims made in his commentary which aim to show that we would be contending experts if both invited to testify on a case involving claims about futile medical treatment. This disagreement aside, taken together both commentaries suggest that my testimony in the case of Andrew Sawatzky is wanting.In the response that follows I do not engage in a debate about the content of my testimony.

Background: Iron deficiency and developmental delay are common in African children. While experimental studies indicate an important role of iron in brain development, effects of iron on child development remain unclear. We aimed to evaluate the effects of iron supplementation or fortification on neurobehavioural outcomes in African children and further summarise these effects in children living in non-African countries for comparison. Methods: We searched PubMed, EMBASE, PsycINFO, Scopus and Cochrane Library for studies published up to 22nd October 2021. We included randomised controlled trials (RCTs) evaluating effects of iron supplementation or fortification on neurobehavioural outcomes in children. Due to heterogeneity in study methods, we analysed all studies qualitatively and in secondary analyses only seven RCTs with 11 arms were meta-analysed. Results: We identified 2231 studies and included 35 studies (n=9988) in the systematic review. Only five studies (n=1294) included African children while 30 (n=8694) included children living in non-African countries. Of the five African studies, two (n=647) reported beneficial effects of iron supplementation on neurobehavioural outcomes in anaemic children, while three (n=647) found no beneficial effects. Of 30 studies in children living in non-African countries, 10 (n=3105) reported beneficial effects of iron supplementation or fortification on neurobehavioural outcomes, seven (n=786) reported beneficial effects only in children who had iron deficiency, iron deficiency anaemia or anaemia while 13 (n=4803) reported no beneficial effects. Conclusions: There are few studies in African children despite the high burden of iron deficiency and developmental delay in this population. Evidence on the effects of iron supplementation on neurobehavioural outcomes remains unclear and there is need for further well-powered studies evaluating these effects in African populations.

Background and Objectives: This review aimed to provide an updated review of evidence regarding the effects of aromatherapy in relieving symptoms of burn injuries, focusing on pain and physiological distress. Materials and Methods: Fifteen databases (including five English databases, four Korean medical databases, and four Iranian databases) and trial registries were searched for studies published between their dates of inception and July 2021. Two review authors individually performed study selection, data extraction, and risk of bias assessment, and any discrepancies were solved by a third review author. Results: Eight RCTs met our inclusion criteria and were analyzed in this updated systematic review. Our meta-analyses revealed that inhaled aromatherapy plus routine care showed beneficial effects in relieving pain after dressing, as compared to placebo plus routine care (p < 0.00001) and routine care alone (p = 0.02). Additionally, inhaled aromatherapy plus routine care (p < 0.00001) and aromatherapy massage plus routine care (p < 0.0001) also showed superior effects in calming anxiety, as compared to routine care alone. None of the included studies reported on AEs. Overall, the risk of bias across the studies was concerning. Conclusions: This updated review and synthesis of the studies had brought a more detailed understanding of the potential application of aromatherapy for easing the pain and anxiety of burn patients.
