Top Ten Tips Palliative Care Clinicians Should Know About the Physical Manifestations of Psychiatric Illness and Treatment.

Addressing the psychiatric aspects of serious illness in palliative care (PC) is crucial to both care delivery and outcomes. Psychiatric comorbidities are common among patients with PC needs and can significantly impact their total burden of symptomatic distress, overall quality of life, functional independence, and healthcare utilization. Yet, these aspects of care are often deferred to mental health consultant teams in the context of busy PC services and often limited human resources. To provide comprehensive and person-centered care, PC clinicians must understand the interplay between medical conditions and psychiatric presentations within a biopsychosocial framework to respond empathically, efficiently, and effectively. This article is the first of a two-part series developed in collaboration with a group of psychiatric-palliative care specialists. This article explores ten common physical manifestations of psychiatric illness and treatment among patients facing serious illnesses. The second article will provide pragmatic tips PC clinicians should know about the psychiatric manifestations of nonpsychiatric serious illness and treatment. Combined, these two articles support a holistic approach that PC clinicians can use to prioritize and integrate both mental and emotional well-being throughout the continuum of serious illness.

Top Ten Tips Palliative Care Clinicians Should Know About the Psychiatric Manifestations of Nonpsychiatric Serious Illness and Treatments.

Mental health issues are widespread and significant among individuals with serious illness. Among patients receiving palliative care (PC), psychiatric comorbidities are common and impact patient quality of life. Despite their prevalence, PC clinicians face challenges in effectively addressing the intricate relationship between medical and psychiatric disorders due to their complex, intertwined and bidirectionally influential nature. This article, created collaboratively with a team of psychiatric-palliative care experts, is the second in a two-part series examining the bidirectional relationship between medical and psychiatric illness in PC. This article explores 10 prevalent psychiatric manifestations associated with severe illness and its treatment. Building upon the first article, which focused on 10 common physical manifestations of psychiatric illness among patients receiving PC, these two articles advocate for an integrated approach to PC that prioritizes mental and emotional wellbeing across the continuum of serious illness.

Prognostic Implications of Delirium After Left Ventricular Assist Device Implantation: A Retrospective Study.

BACKGROUND: In critically ill patients, delirium is a prognostic indicator of morbidity and mortality. OBJECTIVE: This study investigates the impact of a delirium diagnosis on outcomes after left ventricular assist device (LVAD) implantation. METHODS: This retrospective study included all adult patients who received LVADs at our institution between January 2016 and December 2020. We compared preimplantation characteristics between the two groups, with and without a diagnosis of delirium, and compared their outcomes, including 1-month, 6-month, and in-hospital mortality, as well as reintubation rate, length of stay, discharge disposition, and readmission rates. RESULTS: In total, 361 patients (26.7% women and 75.8% African American) received durable LVADs. Ninety-four patients (26.1%) were diagnosed with delirium during the index admission. Preimplantation demographic characteristics, past medical and psychiatric conditions, Interagency Registry for Mechanically Assisted Circulatory Support Profile, and laboratory values did not differ between the two groups with and without a diagnosis of delirium; older age (59 vs 56; P = 0.03) was associated with delirium. Delirium diagnosis was associated with higher 1-month (P = 0.007), 6-month (P = 0.004), and in-hospital mortality (P < 0.001), unplanned reintubations (P < 0.001), and a lower likelihood of discharge home (P = 0.03). Total hospital and intensive care unit length of stay were higher in patients with a diagnosis of delirium, though these results were not statistically significant. Readmission to the hospital after index admission was quicker in patients with a diagnosis of delirium, but this result was not statistically significant. CONCLUSIONS: In this study, a diagnosis of delirium during the LVAD implantation admission was associated with higher mortality, adverse postsurgical outcomes, and unfavorable discharge dispositions. Future prospective research is needed to validate the prognostic implications of delirium in both the short and long term. Additionally, there is a need to identify modifiable risk factors associated with delirium to promote early diagnosis and implement evidence-based management strategies to enhance outcomes within this population.

Palliative Care Psychiatry: Building Synergy Across the Spectrum.

PURPOSE OF REVIEW: Palliative care (PC) psychiatry is a growing subspecialty focusing on improving the mental health of those with serious medical conditions and their caregivers. This review elucidates the current practice and ongoing evolution of PC psychiatry. RECENT FINDINGS: PC psychiatry leverages training and clinical practices from both PC and psychiatry, addressing a wide range of needs, including enhanced psychiatric care for patients with serious medical illness, PC access for patients with medical needs in psychiatric settings, and PC-informed psychiatric approaches for individuals with treatment-refractory serious mental illness. PC psychiatry is practiced by a diverse workforce comprising hospice and palliative medicine-trained psychiatrists, psycho-oncologists, geriatric psychiatrists, other mental health professionals, and non-psychiatrist PC clinicians. As a result, PC psychiatry faces challenges in defining its operational scope. The manuscript outlines the growth, current state, and prospects of PC psychiatry. It examines its roles across various healthcare settings, including medical, integrated care, and psychiatric environments, highlighting the unique challenges and opportunities in each. PC psychiatry is a vibrant and growing subspecialty of psychiatry that must be operationalized to continue its developmental trajectory. There is a need for a distinct professional identity for PC psychiatry, strategies to navigate administrative and regulatory hurdles, and greater support for novel clinical, educational, and research initiatives.

Regional versus general anesthesia in knee arthroplasty in patients with different classes of BMI: A matched analysis of the NSQIP database.

BACKGROUND: Knee arthroplasty for knee arthritis is a commonly performed surgery yielding excellent functional results and good pain relief. It is associated with post-surgical complications according to the type of anesthesia and BMI class. METHODS: The National Surgical Quality Improvement Project database for the years 2005-2012 for patients >18 years of age who underwent knee arthroplasty, condyle and plateau, medial and/or lateral compartment. The surgical site complications, bleeding occurrences necessitating transfusion, unplanned readmissions, and mortality stratified according to anesthesia type and BMI class over a period of 30-days were examined. RESULTS: A total of 78,275 patients were included for analysis; regional anesthesia showed a consistent protective effect from surgical site complications more prominent with increasing obesity class with respective ORs and their corresponding 95% CI for pre-obesity, class I, II, and III obesity being 0.95 [0.89-1.09], 0.75 [0.68-0.83], 0.64 [0.57-0.72], and 0.61 [0.54-0.7]. CONCLUSIONS: Higher BMI values are a protective factor for the risk of bleeding requiring transfusion in patients undergoing total knee arthroplasty. Moreover, regional anesthesia is the preferred choice of anesthesia as well if postoperative complications are considered. A significant decrease in the rate of post-operative blood transfusions was seen in patients with high BMI and regional anesthesia.

The association of antidepressant monotherapy and weight change in a Middle Eastern psychiatric population.

Genetic and lifestyle factors influence weight changes secondary to antidepressants. However, the association between antidepressants and weight changes is seldom studied in Middle Eastern populations who have a unique genetic, lifestyle and dietary profile. This is a chart-based retrospective longitudinal study that describes the 6-month evolution of weight in outpatient Lebanese adults initiated on serotonin reuptake inhibitor (SRI) antidepressant monotherapy, with the exclusion of confounders with metabolic implications. A linear mixed model was used to estimate the association of weight with time. Demographic factors were tested for interaction with the model. The sample consisted of 200 antidepressant trials. After adjusting for baseline weight, age, and sex, weight did not change significantly from week 1 to week 4 (P = 0.530) but significantly increased by 0.15 kg/week from week 4 to week 24 (P < 0.05). Sex, baseline weight, alcohol use, tobacco use, and presence of metabolic condition(s) did not affect weight change (P > 0.05). The same changes were observed across all SRIs and diagnoses. Our results show that SRI monotherapy is associated with weight gain throughout the treatment course in a Middle Eastern population. We recommend judicious prescription of SRIs and clinical vigilance over weight throughout the course of treatment in these populations.

The Role of Epigenetics in Addiction: Clinical Overview and Recent Updates.

Addiction is an international public health problem. It is a polygenic disorder best understood by accounting for the interplay between genetic and environmental factors. A recent way of perceiving this interaction is through epigenetics, which help grasp the neurobiological changes that occur in addiction and explain its relapsing-remitting nature. It is now known that every cell has a different way of expressing its phenotype, despite a universal DNA sequence. This is particularly true in the central nervous system where environmental factors influence this expression. Three major epigenetic processes have been found to participate in the perpetuation of addiction by changing the state of the chromatin and the degree of gene transcription: histone acetylation and methylation, DNA methylation, and noncoding RNAs. In the animal model literature, substantial evidence exists about the role of these epigenetic changes in the different phases of substance use disorders. This book chapter is a non-systematic literature review of the recent publications tackling the topic of epigenetics in addiction. Even though this evidence remains scarce and relatively poorly systematized, it is a promising foundation for future research of molecules that target specific brain regions and their functions to address core behavioral changes seen in addiction.

Use of Cholinesterase Inhibitors in Non-Alzheimer's Dementias.

Non-Alzheimer's dementias constitute 30% of all dementias and present with major cognitive and behavioral disturbances. Cholinesterase inhibitors improve memory by increasing brain acetylcholine levels and are approved symptomatic therapies for Alzheimer's disease (AD). They have also been investigated in other types of dementias with potential cholinergic dysfunction. There is compelling evidence for a profound cholinergic deficit in Lewy Body dementia (LBD) and Parkinson's disease dementia (PDD), even to a greater extent than AD. However, this deficit is difficult to objectivize in vascular dementia (VaD) given the increased comorbidity with AD. Furthermore, there is minimal to no evidence for cholinergic loss in frontotemporal dementia (FTD). Although cholinesterase inhibitors showed significant improvement in cognitive, behavioral, and functional measures in both LBD and PDD clinical trials, only rivastigmine is approved for PDD, due to the heterogeneity of the scales used, the duration of trials, and the limited sample sizes impacting data interpretation. Similarly, the interpretation of findings in VaD trials are limited by the lack of pre-defined inclusion criteria for 'pure VaD' and the wide heterogeneity of patients enrolled with respect to location and extent of cerebrovascular disease. In FTD patients, cholinesterase inhibitors were mostly associated with worsening of cognitive and behavioral symptoms. In non-AD dementias, cholinesterase inhibitors were well tolerated, with increased reports of mild to moderate cholinergic side effects and a non-significant trend for increased cardio and cerebrovascular events with rivastigmine in VaD, justifying their cautious use on a case-by-case basis, especially when there is evidence for cholinergic deficit.

Attitudes, beliefs, and knowledge of substance use amongst youth in the Eastern Mediterranean region: A systematic review.

BACKGROUND: Substance use has a tremendous impact on the burden of disease. This is particularly true in the Eastern Mediterranean region (EMR), where many countries serve as suppliers of drugs. As risk perception and frequency of use are inversely correlated, targeting perception during adolescence becomes essential for prevention. In this study, we systematically reviewed the literature on attitudes, beliefs, and knowledge of substance use amongst youth in the EMR. METHODS: We reviewed quantitative articles addressing attitudes, beliefs, and knowledge of youth aged between 13 and 25 years towards substance use in the EMR. We searched MEDLINE, PubMed, Cochrane, PsycInfo, and PsycArticles then applied a duplicate independent method for study selection and screening. Two reviewers completed data abstraction and a narrative summary of findings. RESULTS: Our search generated 12,810 articles. Five cross-sectional studies were eligible (two analytic and three descriptive). The analytic studies described a significant correlation between intention to use and both attitudes and subjective norms. The descriptive studies portrayed a negative attitude towards use with a low threshold for considering it as serious. Beliefs pertaining to reasons for use included stress and sleeping, whereas thoughts on treatment were restricted to traditional methods based on personal resilience and religious support. Knowledge about substance use symptoms, withdrawal, and treatment was low. CONCLUSION: Our review ascertains the role of sociocultural moral prohibition and awareness of mental health as major influencers in shaping the perception of substance use. Further research is needed to elaborate culturally-tailored survey tools.
