The possible clinical utility of the alcohol biomarker phosphatidylethanol for managing suspected alcohol withdrawal in hospitalized patients: A case report

BACKGROUND AND OBJECTIVES

The decision to initiate pharmacotherapy for alcohol withdrawal is typically based on examining self-reported use of alcohol and symptoms of withdrawal. Phosphatidylethanol (PEth) is a biomarker that could aim in clinical decision-making in withdrawal management.

METHODS

This report describes three cases highlighting the potential clinical utility of PEth in caring for individuals at risk for alcohol withdrawal.

RESULTS

Two of the cases received phenobarbital when their PEth showed that the risk of withdrawal was low and one case where PEth could have shown this was needed. The results were only available in a delayed fashion, however, could have been useful in informing clinical care.

DISCUSSION AND CONCLUSION

PEth can be a useful tool if available without delay. PEth can be used to quickly rule out alcohol withdrawal and avoid misdiagnoses and prolonged hospital stays.

SCIENTIFIC SIGNIFICANCE

This is a clinical case study available looking at PEth and withdrawal in hospitalized patients. It proposes that PEth can be used as a way to quickly rule out alcohol withdrawal to avoid misdiagnoses and the possibility of a prolonged hospital stay.

New Synthetic Opioids: Clinical Considerations and Dangers

Since the early 2010s, synthetic opioids have significantly contributed to overall opioid-related overdose mortalities. For point of reference, of the 68,630 opioid-related deaths recorded in 2020, 56,516 involved synthetic opioids. During much of this period, fentanyl has been the most commonly used synthetic opioid. This time when fentanyl was the most popular opioid has been called the "third wave" of the opioid crisis, partly because it led to a sharp rise in deaths from overdoses. Other synthetic opioids, such as carfentanil, protonitazene, and isotonitazene, have also become more widely diverted for nonmedical used. Carfentanil is an even more potent fentanyl derivative that was initially used in the mid-1980s as a general anesthetic for large animals such as elephants. Related to its strong affinity for mu opioid receptors, carfentanil is still utilized in medicine and science today as a radiotracer for positron emission tomography imaging. Protonitazene and isotonitazene belong to a novel class of synthetic opioids called benzimidazoles that were manufactured in the 1950s as novel analgesics. These agents have come under recent scrutiny as designer synthetic opioids becoming more prevalent. However, to date, there is incomplete data regarding the prevalence of synthetic opioids, as traditional toxicology screenings may not be sensitive to detect these compounds at such low doses post-mortem, particularly when blood is drawn from the periphery instead of central tissues such as the brain, lung, or heart. This narrative review aims to highlight the clinical challenges presented by these new synthetic opioids.

Centering Culture in Mental Health: Differences in Diagnosis, Treatment, and Access to Care Among Older People of Color

Mental healthcare disparities are routinely documented, yet they remain wider than in most other areas of healthcare services and common mental disorders (depression and anxiety) continue to be one of the highest health burdens for older people of color. To address disparities in mental health services for older people of color, the narrative must move beyond simply documenting these inequities and attain a better understanding of the internalized, interpersonal, systemic, and medical racism that have harmed these communities and excluded them from its services in the first place. It is imperative that researchers, clinicians, and policymakers acknowledge the realities of racism and discrimination as leading causes of mental healthcare disparities. Therefore, this review is a call-to-action. Authors adopt an antiracist and health equity lens in evaluating the differing needs of Blacks/African-Americans, Asian Americans, and Latinos by exploring psychiatric comorbidity, experiences with seeking, accessing, and engaging in treatment, and the unique cultural and psychosocial factors that affect treatment outcomes for these diverse groups. Further, authors offer researchers and practitioners tangible tools for developing and implementing culturally-sensitive, mental health focused interventions for older people of color with special attention placed on cultural adaptations, models of care, prevention, and practical strategies that can be implemented to reduce disparities and increase equity in mental healthcare.

Older Latino Mental Health: A Complicated Picture

The aggregation of Latino subgroups in national studies creates an overly simplistic narrative that Latinos are at lower risk of mental illness and that foreign nativity seems protective against mental illness (i.e., immigrant paradox). This broad generalization does not hold up as the Latino population ages. Given that social inequalities for risk appear to widen with age, the social disadvantages of being Latino in the United States increase the risk for mental illness across the life span. This review focuses on the mental health of older Latinos, specifically the 3 subgroups with the longest residential history in the United States—Mexicans, Puerto Ricans, and Cubans. We examine relevant epidemiological and clinical psychopathology studies on aging in these Latino populations and present evidence of the heterogeneity of the older Latino population living in the United States, thus illustrating a limitation in this field—combining Latino subgroups despite their diversity because of small sample sizes. We address the migration experience—how intraethnic differences and age of migration affect mental health—and discuss social support and discrimination as key risk and protective factors. We conclude with a discussion on meeting the mental health needs of older Latinos with a focus on prevention, a promising approach to addressing mental illness in older Latinos, and future directions for mental health research in this population. Success in this endeavor would yield a substantial reduction in the burden of late-life depression and anxiety and a positive public health impact.

Neuroimaging Education in Psychiatry Residency Training: Needs Assessment

OBJECTIVE

The authors investigated the attitudes, self-perceived knowledge, and the need for a dedicated neuroimaging curriculum among psychiatrists-in-training.

METHODS

An anonymous voluntary 20-item Web-based survey was distributed to psychiatry residents at seven university-based USA programs between December 2017 and February 2019.

RESULTS

Of 302 psychiatry residents, 183 (response rate, 60.5%) completed the survey. Although a large majority of residents (83%) believed that neuroradiology education is important to psychiatric training, only 7% reported that they are receiving adequate training in this discipline. The majority (80%) believed that there should be a formal neuroimaging curriculum during their training. Self-perceived competence and comfort level was found to be low with several psychiatrically relevant neuroimaging modalities. In particular, regarding CT head/brain MRI, there was a marked difference in self-perceived competence at interpreting the actual brain images (8%) versus the radiological reports/impression summaries (48%). Comfort level with functional neuroimaging was especially low (7%). Clinically, only 26% reported confidence at being able to explain neuroimaging topics to patients. Compared to junior residents, senior residents rated higher confidence at interpreting the radiological reports/impression summaries of CT head/brain MRI (p = 0.008) and PET/SPECT (p = 0.014), but no difference was found with the actual brain images. Further, senior residents were less likely to identify with "neurophobia" (p = 0.028) and more likely to believe that a neuroimaging curriculum should be included in psychiatric residency training (p = 0.027) when compared to junior residents.

CONCLUSIONS

Psychiatrists-in-training have a very strong interest in neuroimaging education. Future educational interventions should address this need.

Physical Examination Skills Among Chief Residents in Psychiatry: Practices, Attitudes, and Self-Perceived Knowledge

OBJECTIVES

The authors investigated the attitudes, self-perceived competence, and the need for a dedicated curriculum on physical examination skills among chief residents in psychiatry.

METHODS

A voluntary 28-item web-based questionnaire was distributed to psychiatry chief residents in the USA between January 2019 and February 2019.

RESULTS

Of 181 chief residents, 79 (response rate, 44%) completed the online survey. The majority of chief residents want to improve their physical exam skills (64%) and believe that there should be a targeted curriculum aimed at incorporating these skills into everyday psychiatric practice (63%). However, most (57%) chief residents reported that they only conduct physical exams on a few selected patients (< 25% of the time) and almost half (48%) last used a stethoscope a year ago, if not longer. Self-perceived competence and comfort level with neurology-related exam findings was especially low: only 35% could identify discrepant neurological findings and 33% elicit Hoover's sign of leg paresis. A significant majority (86%) believed that performing a physical exam would not interfere with the therapeutic relationship.

CONCLUSIONS

Although chief residents in psychiatry believe that developing competence in physical examinations is important to their education, the current educational landscape does not support the development of these skills. Future educational strategies should focus on addressing this need.

Use of gen-probe probe competition assay as a supplement to probes for direct detection of Chlamydia trachomatis and Neisseria gonorrhoeae in urogenital specimens

The potential for development of a cost-effective protocol for selective use of the Gen-Probe probe competition assay (PCA) in conjunction with PACE 2 for direct detection of Chlamydia trachomatis and Neisseria gonorrhoeae in urogenital specimens that would not compromise patient care was investigated. To accomplish this, PCA data from testing performed over 12 months were retrospectively reviewed. Of 237 samples that were presumptively positive for C. trachomatis by initial probe assay and could be tested by PCA, positive PCA results were obtained for 100, 79, and 59%, respectively, of specimens that gave a signal of more than 1,500, 1,000 to 1,500, and less than 1,000 relative light units (RLU). For the 141 specimens that were presumptively positive for N. gonorrhoeae and could be tested by PCA, positive PCA results were obtained for 99, 80, and 42%, respectively, of samples with a signal of more than 1,500, 1,000 to 1,500, and less than 1,000 RLU. These data indicate that PCA should be a routine supplement to Gen-Probe PACE 2 for specimens with an initial signal by probe assay of less than 1,500 RLU and may not be necessary for samples yielding a signal of more than 1,500 RLU.
