Background: The COVID-19 pandemic has been an inciting factor for a wide variety of neuropsychiatric symptoms, including first-episode psychosis (FEP)., Objective: The aim of this systematic review was to summarize the current literature on COVID-19 associated postviral FEP., Methods: A systematic review was completed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and identified 81 articles that met inclusion criteria., Results: Articles included case reports, case series, and cohort studies with postviral FEP occurring outside the setting of delirium, demonstrating a broad range of symptoms., Conclusions: This systematic review shows that postviral FEP associated with COVID-19 follows a pattern similar to psychosis associated with other viral infections and is an important consideration when building a differential for FEP when delirium has been ruled out. Better understanding of postviral FEP associated with COVID-19 and other viral illnesses may help clarify aspects of underlying pathophysiology of psychotic symptoms broadly., (Copyright © 2023 Academy of Consultation-Liaison Psychiatry.

Background: Agitation is a common reason for psychiatric consultation in the general hospital. The consultation-liaison (CL) psychiatrist is often tasked with teaching the medical team how to manage agitation., Objective: The purpose of this scoping review is to explore what resources the CL psychiatrist has for educational tools on teaching about agitation management. Given the frequency with which CL psychiatrists help with on-the-ground management of agitation, we hypothesized that there would be a scarcity of educational resources to teach front-line providers how to manage agitation., Methods: Following current Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a scoping review was conducted. The literature search focused on the electronic databases MEDLINE (PubMed), Embase (Embase.com), The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Methodology Register), PsycInfo (EbscoHost), Cumulated Index to Nursing and Allied Health Literature (CINAHL) (EbscoHost), and Web of Science. Using Covidence software, after screening for titles and abstracts, full texts were screened independently and in duplicate according to our inclusion criteria. For data extraction, we created a predefined set of criteria according to which each article was analyzed. We then grouped the articles in the full-text review according to which patient population a curriculum was designed for., Results: The search yielded a total of 3250 articles. After removing duplicates and reviewing procedures, we included 51 articles. Data extraction captured article type and details; educational program information (staff training, web modules, instructor led seminar); learner population; patient population; and setting. The curricula were further divided based on their target patient population, specifically the acute psychiatric patient (n = 10), the general medical patient (n = 9), and the patient with a major neurocognitive disorder such as dementia or traumatic brain injury (n = 32). Learner outcomes included staff comfort, confidence, skills, and knowledge. Patient outcomes included measurements of agitation or violence using validated scales, PRN medication use, and restraint use., Conclusions: Despite there being numerous agitation curricula in existence, we found that a large majority of these educational programs were done for patients with major neurocognitive disorders in the long-term care setting. This review highlights the gap in education related to agitation management for both patients and providers in the general medical setting, as less than 20% of total studies are focused on this population. The CL psychiatrist plays a critical role in assisting in agitation management in this setting, which often requires collaboration between technicians, nurses, and nonpsychiatric providers. It calls into question whether the lack of educational programs makes the implementation of management interventions more difficult and less effective, even with the assistance of the CL psychiatrist., (Copyright © 2023 Academy of Consultation-Liaison Psychiatry.

Background: Although lithium is considered the gold-standard treatment for bipolar disorder (BD), it is associated with a variety of major endocrine and metabolic side effects, including parathyroid hormone (PTH) dependent hypercalcemia. Aside from surgery and medication discontinuation, there are limited treatments for hypercalcemia. This paper will assess data from a randomized controlled trial (RCT)., Methods: This is a secondary analysis of an RCT that explored the effects of atorvastatin (n = 27) versus placebo (n = 33) on lithium-induced nephrogenic diabetes insipidus (NDI) in patients with BD and major depressive disorder (MDD) using lithium (n = 60), over a 12-week period. This secondary analysis will explore serum calcium levels and thyroid stimulating hormone (TSH) measured at baseline, week 4, and week 12., Results: At 12-weeks follow-up while adjusting results for baseline, linear regression analyses found that corrected serum calcium levels were significantly lower in the treatment group (mean (M) = 2.30 mmol/L, standard deviation (SD) = 0.07) compared to the placebo group (M = 2.33 mmol/L, SD = 0.07) (β = - 0.03 (95% C.I.; - 0.0662, - 0.0035), p = 0.03) for lithium users. There were no significant changes in TSH., Conclusion: In lithium users with relatively normal calcium levels, receiving atorvastatin was associated with a decrease in serum calcium levels. Although exciting, this is a preliminary finding that needs further investigation with hypercalcemic patients. Future RCTs could examine whether atorvastatin can treat PTH dependent hypercalcemia due to lithium and other causes., (© 2022. The Author(s).)

Introduction: Social-distancing due to COVID-19 has led to social isolation, stress, and mental health issues in older adults, while overwhelming healthcare systems worldwide. Telehealth involving phone calls by trained volunteers is understudied and may be a low-cost, scalable, and valuable preventive tool for mental health. In this context, from patient participatory volunteer initiatives, we have adapted and developed an innovative volunteer-based telehealth intervention program for older adults (TIP-OA). Methods and analysis: To evaluate TIP-OA, we are conducting a mixed-methods longitudinal observational study. Participants: TIP-OA clients are older adults (age ≥ 60) recruited in Montreal, Quebec. Intervention: TIP-OA volunteers make weekly friendly phone calls to seniors to check in, form connections, provide information about COVID-19, and connect clients to community resources as needed. Measurements: Perceived stress, fear surrounding COVID-19, depression, and anxiety will be assessed at baseline, and at 4- and 8-weeks. Semi-structured interviews and focus groups will be conducted to assess the experiences of clients, volunteers, and stakeholders. Results: As of October 15th, 2020, 150 volunteers have been trained to provide TIP-OA to 305 older clients. We will consecutively select 200 clients receiving TIP-OA for quantitative data collection, plus 16 volunteers and 8 clinicians for focus groups, and 15 volunteers, 10 stakeholders, and 25 clients for semi-structured interviews. Discussion: During COVID-19, healthcare professionals' decreased availability and increased needs related to geriatric mental health are expected. If successful and scalable, volunteer-based TIP-OA may help prevent and improve mental health concerns, improve community participation, and decrease healthcare utilization.

The high comorbidity of medical and psychiatric diagnoses in the general hospital population requires collaboration between various medical fields to provide comprehensive health care. This study aims to find the rate of psychiatric consultations, their timing and overall diagnostic trend in comparison to previous studies. Tehran University of Medical Sciences has got an active psychiatric consultation-liaison service which includes services provided by four faculty psychiatrists (two full-time and two part-time). This study was done in two general hospitals by simple sampling in available cases. For each consultation, a board-certified faculty psychiatrist conducted a clinical evaluation based on DSM-IV-TR. Other than psychiatric diagnoses, socio-demographic variables, relative consultation rates, reasons for referral, medical diagnoses and the time stay after admission were assessed. Among 503 patients who were visited by the consultation-liaison service, there were 54.3% female with mean age of 39.8 years. In 90.1% of consultations, at least one DSM-IV-TR diagnosis was made. The most frequent diagnosis groups were mood disorder (43.5%), adjustment disorder (10.9%) and cognitive disorder (7.6%). In about 10.9% of the consultations, multiple psychiatric diagnoses were made. The mean length of hospital stay before the consultation was 12.56 days (range=1-90, SD=13). Based on our findings, the mood and cognitive disorders still remain major foci of consultation-liaison practice in general hospitals; however our findings showed high rate of adjustment disorders diagnosis and ambiguous request for psychiatric consultation which need more interdisciplinary interaction.

Background: There exists a high prevalence of psychiatric disorders in dermatological patients. Although, investigators have evaluated psychiatric aspects of the patients suffering from skin diseases; there are rare studies concerning mental health in pemphigus patients. The objective of this study was to evaluate mental health status and quality of life of newly diagnosed pemphigus patients., Materials and Methods: Between April 2007 and June 2008, all newly diagnosed pemphigus patients attending the outpatient clinic of a dermatological hospital were given a questionnaire comprising the GHQ-28 and DLQI to fill out., Results: Of 283 patients, 212 complete forms were returned. The bimodal score of GHQ ranged from 0 to 26 (Mean = 9.4) and the Likert score of GHQ ranged from 6 to 68 (Mean = 31.9). The DLQI score ranged between 0 and 30 (Mean of 13.8). A total of 157 patients (73.7%) were yielded to be possible cases of mental disorder considering GHQ-28 bimodal scores. Significant correlation was detected between the DLQI score and bimodal and Likert scoring of GHQ-28., Conclusion: Our study has depicted high prevalence of psychiatric comorbidity in pemphigus patients. It underlines the fact that physicians, who are in-charge of care for these patients, are in an exceptional position to distinguish the psychiatric comorbidity and to take appropriate measures.

Objectives: Graft stenosis is a major complication of coronary artery bypass grafting with autologous saphenous vein grafts. Nitric oxide (NO) is believed to prevent this phenomenon. We studied the effect of perivascular application of an NO donor on the degree of stenosis of such grafts in an ovine model., Methods: Twenty white Iranian ewes were randomized to coronary artery bypass grafting using autologous saphenous vein grafts with application of an elastomer gel containing diethylenetriamine NO adduct in 0.9% sodium chloride solution around the grafted vessel (intervention group) or with the gel containing the saline solution alone (controls). Graft vessels were studied after 1 year using spot angiography and histological examination., Results: The mean degree of stenosis was significantly lower in the intervention group than in the controls as found by histology (92.3 ± 5.5 vs. 80.9 ± 8.3%; p = 0.004). Although the difference in the angiographic score was not significant, the mean score was still lower in the intervention group (9.5 ± 11.3 vs. 12.0 ± 11.8)., Conclusions: Perivascular application of an NO donor was, at least histologically, effective in reducing graft stenosis in our ovine model. This can be a step toward the development of drug-eluting coronary artery bypass grafts., (Copyright © 2011 S. Karger AG, Basel.)

Purpose: Caesarean delivery in the absence of any medical indications has become a major issue of concern among the women's health professionals. The patients' choice of caesarean is influenced by several factors predominating by their physicians' suggestion. Our objective was to examine factors that may affect the physicians' responses to patients consulting the mode of delivery., Methods: Questionnaires were posted to 1,000 female obstetricians and gynaecologists practicing in Tehran in winter 2007. Questionnaires included demographic information of physicians and their history of pregnancy and delivery. Finally, they were asked their preferred mode of delivery and the mode they suggest when being consulted by parturient., Results: From 1,000 physicians, 785 cases (78.5%) responded to the survey. The rate of responses in favour of suggesting normal vaginal delivery, Caesarean Section and painless vaginal delivery was 60.8, 25.6 and 13.6%, respectively. There was a correlation between the suggested and the preferred mode of delivery, it means that the physicians mostly suggested their self-preferred mode of delivery to their patients., Conclusions: Physicians normally suggest to their patients as the safe mode of delivery what they prefer for themselves. This preference and subsequent suggestion is influenced by different factors including their age, marital status, and previous modes of delivery. As conclusion, it is inferred that informing a physician to choose the right mode of delivery for herself leads to better suggestions to the patients.

Nitric oxide (NO) has been shown to prevent neointimal hyperplasia and decrease atherosclerosis in several animal models. It is a major modulator of vascular homeostasis and has vasoprotective effects against atherosclerosis. However, NO-based therapies with such purposes have not been used in the clinical arena. Our objective was to combine a medical grade elastomer and an NO donor, diethylenetriamine NO adduct (DETA/NO), to determine whether its perivascular administration can attenuate atherosclerosis and vascular injury. Aortic intimal injury was produced using paediatric pulmonary valvoplasty catheter in 22 healthy male New Zealand White rabbits, which were fed a high-cholesterol diet for 4 weeks beforehand. A mixture of the elastomer Silastic and DETA/NO was applied locally to cover the aortas in the experiment group. After 6 additional weeks on the high-cholesterol diet, the aortas and blood samples were harvested for pathologic analysis and comparison with the control group. Mean atherosclerosis and vascular injury surface area was 6.68 x 10(5) microm2 in the experiment group, compared with 3.44 x 10(5) microm2 in the controls. However, there was no statistically significant difference in atherosclerotic surface area between the two groups. Perivascular application of the NO donor DETA/NO, in the concentration we used, did not prevent atherosclerosis in high cholesterol-fed rabbits. This finding prompts more careful assessment before possible clinical uses.
