Empathy in Undergraduate Medical Students of Bangladesh: Psychometric Analysis and Differences by Gender, Academic Year, and Specialty Preferences

Empathy is considered to be associated with better patient compliance, satisfaction, and clinical outcomes. The aim of the study is to measure and examine empathy among a sample of undergraduate medical students of Bangladesh. It was a cross-sectional study and all the medical students of first through fifth year enrolled at Chattagram Maa-O-Shishu Hospital Medical College during the study period of 2014 were surveyed. Participants anonymously completed the Jefferson Scale of Empathy Medical Student version translated into Bengali language, a valid and reliable 20-item self-administered questionnaire. Principal component factor analysis with varimax rotation and Cronbach’s alpha coefficient were calculated to check validity and reliability of the scale. ANOVA was used to examine the differences in empathy between gender, academic years, and specialty preferences. The mean empathy score was 110.41 ± 13.59. Cronbach’s alpha coefficient was 0.88. There were significant associations between gender and empathy scores. The level of empathy in medical students gradually increases after clinical training in medical college. A nonsignificant difference was found between empathy scores and specialty preferences. It is suggested that the medical curriculum in Bangladesh should include more extensive program to promote empathy and other humanistic values among the medical students.

Ziprasidone as Adjunctive Therapy in Severe Bipolar Patients Treated with Clozapine

Aim. To confirm the efficacy and tolerability of ziprasidone as adjunctive therapy in bipolar patients partially responding to clozapine or with persisting negative symptoms, overweight, or with metabolic syndrome. Methods. Eight patients with psychotic bipolar disorder were tested with the BPRS, the HAM-D, and the CGI at T0 and retested after 2 weeks (T1). Plasma clozapine and norclozapine levels and BMI were tested at T0 and T1. Results. Ziprasidone was well tolerated by all the patients. BPRS and HAM-D scores were reduced in all patients. BMI was reduced in patients with a BMI at T0 higher than 25. Plasma levels of clozapine and norclozapine showed an irregular course.

Clinical Practice Guidelines in Psychiatry: More Confusion Than Clarity? A Critical Review and Recommendation of a Unified Guideline

The discipline of psychiatry has a plethora of guidelines, designed to serve the needs of the clinician. Yet, even a cursory glance is enough to discern the differences between the various guidelines. This paper reviews the current standard guidelines being followed across the world and proposes a unified guideline on the backbone of current evidence and practice being followed. The algorithm for pharmacological and psychosocial treatment for bipolar disorder, major depressive disorder, and schizophrenia is formulated after cross-comparison across four different guidelines and recent meta-analytical evidence. For every disorder, guidelines have different suggestions. Hence, based on the current status of evidence, algorithms have been combined to form a unified guideline for management. Clinical practice guidelines form the basis of standard clinical practice for all disciplines of medicine, including psychiatry. Yet, they are often not read or followed because of poor quality or because of barriers to implementation due to either lack of agreement or ambiguity. A unified guideline can go a long way in helping clear some of the confusion that has crept in due to the use of different guidelines across the world.

The Psychogeriatric Patient in the Emergency Room: Focus on Management and Disposition

Background. The growing geriatric population in the United States (US) has prompted better understanding of treatment of the elderly in the hospital and emergency room (ER) settings. This study examines factors influencing the disposition of psychogeriatric patients after their initial presentation in the ER. Methods. Data was collected on patients 65 years of age or older arriving at the ER of a large urban hospital in the USA (January 2009–December 2010). Results. Of the total subjects (n=95) included in the study, majority were females (66.3%) with an average age of 75.5 years. The chief complaint for psychogeriatric patients coming to the ER was delirium (61.6%). Caucasians were significantly more likely than African-American patients to get a psychiatric consult (33% versus 9%). Patients with delirium were less likely than patients with other psychiatric complaints to get a psychiatric consult in the ER (1.2% versus 47.2%) and less likely to be referred to a psychiatric inpatient unit compared to patients with other psychiatric complaints (2.4% versus 16.7%). Conclusion. Even though delirium is the most common reason for ER visits among psychogeriatric patients, very few delirium patients got a psychiatric consultation in the ER. A well-equipped geriatric psychiatry unit can manage delirium and associated causes.

Metabotropic Glutamate Receptor 5 Negative Modulation in Phase I Clinical Trial: Potential Impact of Circadian Rhythm on the Neuropsychiatric Adverse Reactions—Do Hallucinations Matter?

Metabotropic Glutamate Receptor 5 (mGluR5) negative allosteric modulators (NAMs) may play a role in some psychiatric disorders such as anxiety and depression. The pharmacokinetic profile and pharmacodynamics effects of mGluR5-NAMs have been previously reported. We performed a post hoc analysis of pharmacological and clinical data obtained from 18 young healthy female subjects who received a mGluR5-NAM in the context of a phase I drug-drug interaction study between a mGluR5 NAM and a monophasic oral contraceptive. mGluR5-NAM was administered in an escalating bidaily dose level design. There was no interaction between the OC and mGluR5-NAM. Higher morning mGluR5-NAM plasma concentrations were found compared to evening concentrations. Most of the observed clinically significant neuropsychiatric adverse reactions occurred nocturnally and included visual (pseudo) hallucinations, insomnia accompanied by secondary behavioural disorders, and cognitive dysfunction symptoms of sufficient severity to interfere with daily functioning. Circadian rhythm-related physiological variations in drug absorption and disposition may explain this pharmacokinetics-pharmacodynamics apparently disproportionate relationship. We suggest that clinical trials evaluating basic pharmacokinetic properties of psychiatric medications consider potential drug's chronopharmacokinetics. This may assist with dose optimization and minimize serious neuropsychiatric adverse reactions in the vulnerable psychiatric patient.

Different Neural Responses to a Moral Valence Decision Task in Unipolar and Bipolar Depression

Objectives. Patients affected by bipolar disorder (BP) and major depressive disorder (UP) share the susceptibility to experience depression and differ in their susceptibility to mania, but clinical studies suggest that the biological substrates of the two disorders could influence the apparently similar depressive phases. The few brain imaging studies available described different brain metabolic and neural correlates of UP and BP. Methods. We studied the BOLD neural response to a moral valence decision task targeting the depressive biases in information processing in 36 subjects (14 BP, 11 UP, and 11 controls). Results. Main differences between UP and controls and between UP and BP were detected in left ventrolateral prefrontal cortex (PFC, BA 47). Neural responses of BP patients differed from those of control subjects in multiple brain areas, including anterior cingulate cortex (ACC) and medial PFC, bilateral dorsolateral PFC, temporal cortex and insula, and parietal and occipital cortex. Conclusions. Our results are in agreement with hypotheses of dysfunctions in corticolimbic circuitries regulating affects and emotions in mood disorders and suggest that specific abnormalities, particularly in ventrolateral PFC, are not the same in UP and BP depression.

No Association between Depression and Risk of Hepatocellular Carcinoma in Older People in Taiwan

Objectives. The objective of this study was to determine whether there is a relationship between depression and risk of hepatocellular carcinoma (HCC) in older people in Taiwan. Methods. A case-control study was conducted to analyze the database from the Taiwan National Health Insurance program. We selected 1815 subjects aged 65 years or older with newly diagnosed HCC as the case group and 7260 subjects without HCC as the comparison group, from 2000 to 2010. Both groups were compared to measure the risk of HCC. Results. After controlling for confounders, the odds ratio of HCC was 0.81 in subjects with depression (95% confidence interval = 0.59, 1.11), as compared with nondepressed subjects. Conclusions. We conclude that no association is detected between depression and risk of hepatocellular carcinoma in older people in Taiwan.

Individuals Diagnosed with Schizophrenia Assign Emotional Importance to Neutral Stimuli: An fMRI Study

The majority of functional neuroimaging studies investigating neural correlates of emotion processing in schizophrenia report a significant deficit in limbic structures activation in patients relative to control participants. Recently it has been suggested that this apparent “deficit” could be due to an enhanced sensitivity of the neutral material in individuals diagnosed with schizophrenia, rather than due to their inefficiency in emotion processing. The purpose of the present study was to test this supposition and verify if the potential effect is present in both men and women diagnosed with schizophrenia. In order to do that we examined the pattern of cerebral activation associated with processing of neutral stimuli in schizophrenia. Thirty-seven schizophrenia patients and 37 healthy controls viewed neutral and emotional images while in a functional magnetic resonance imaging scanner. Schizophrenia patients rated the neutral images as more emotionally salient than controls. Additionally, patients showed significant activation during processing of neutral images in limbic and prefrontal regions; similar areas were underactivated in patients relative to controls during processing of emotional information. Investigation of sex differences revealed that the enhanced responsiveness to the emotionally neutral material was attributed primarily to men with schizophrenia.

Emotional and Cognitive Empathy in First-Year Medical Students

Objectives. Doctors’ empathy towards their patients is considered important for treatment outcome. However, during medical school there might be a decline in empathy called “hardening of the heart.” This study evaluated the cognitive and emotional empathy in medical students and investigated the influence of a preference for a specialty and students attachment styles. Methods. 126 first-year medical students were included and completed the Reading the Mind in the Eyes Test revised version (RME-R), the Balanced Emotional Empathy Scale (BEES), and the Experiences in Close Relationships-Revised Adult Attachment Questionnaire (ECR-R). Results. Students identified of 36 photographs in the RME-R test correctly (norm: 26). The female students’ mean BEES total score was and the male students’ ; . The female students’ mean BEES score was significantly () below the female norm of 60. Students who preferred a specialty with continuity of patient care scored significantly higher in the BEES (). A more avoidant attachment style was associated with a lower BEES score (). Conclusion. The students showed low emotional and cognitive empathy scores and an avoidant attachment style. This supports the inclusion of specific training in cognitive and emotional empathy in medical education.

A Novel Model of Schizophrenia Age-of-Onset Data Challenges the Conventional Interpretations of the Discordance in Monozygote Twin Studies

The relative importance of genetics and the environment in causing schizophrenia is still being debated. Although the high proportion of monozygote cotwins of schizophrenia patients who are discordant suggests that there may be a significant environmental contribution to the development of schizophrenia, this discordance is predicted by an accumulative multimutation model of schizophrenia onset constructed here implying a genetic origin of schizophrenia. In this model, schizophrenics are viewed as having been born with the genetic susceptibility to develop schizophrenia. As susceptible gene carriers age, they randomly accumulate the necessary mutations to cause schizophrenia, the last needed mutation coinciding with disease onset. The mutation model predicts that the concordance rate in monozygote twin studies will monotonically increase with age, theoretically approaching 100% given sufficient longevity. In dizygote cotwins of schizophrenia patients, the model predicts that at least 71% of cotwins are incapable of developing schizophrenia even though every cotwin and their schizophrenic twin shared a similar early environment. The multimutation model is shown to fit all of the monozygote and dizygote concordance rate data of the principle classical twin studies completed before 1970 considered in this paper. Thus, the genetic hypothesis of schizophrenia can be tested by bringing these studies up to date.
