The reciprocal relationship between suicidality and stigma

Introduction: Although suicidality is frequently the cause of stigma, it is conversely true that stigma may be the cause of suicidality. The present paper focuses on the complex relationships that exist between suicidal behavior and stigmatizing attitudes. Methods: A narrative review of the topic will be presented on the basis of the relevant literature collected from an electronic search of PubMed, ISI Web of Knowledge, and Scopus databases, using stigma, public stigma, structural stigma, perceived stigma, self-stigma, suicide, attempted suicide, and suicidality as key words. Results: A negative perception is frequently held of suicidal people, labeling them as weak and unable to cope with their problems, or selfish. Individuals who have attempted suicide are subject to similar processes of stigmatization and "social distancing"; insurance policies include an exclusion clause against death by suicide. Subjects with a direct personal experience of depression or suicide strongly endorse a feeling of self-stigma; those who have attempted suicide are often ashamed and embarrassed by their behavior and tend to hide the occurrence as much as possible. Similar processes are observed among family members of subjects who have committed suicide or made a suicide attempt, with a higher perceived stigma present in those bereaved by suicide. Perceived or internalized stigma produced by mental or physical disorders, or through belonging to a minority group, may represent a significant risk factor for suicide, being severely distressing, reducing self-esteem and acting as a barrier in help-seeking behaviors. Conclusion: With the aim of preventing suicide, greater efforts should be made to combat the persisting stigmatizing attitudes displayed toward mental disorders and suicide itself. Indeed, the role of stigma as a risk factor for suicide should further motivate and spur more concerted efforts to combat public stigma and support those suffering from perceived or internalized stigma. Experts and scientific societies should form an alliance with the media in an effort to promote a marked change in the societal perception of mental health issues and suicide. As stigma may result in severe consequences, specialist care and psychological interventions should be provided to populations submitted to stigma

Delusional Infestation in a Patient with Renal Failure, Metabolic Syndrome, and Chronic Cerebrovascular Disease Treated with Aripiprazole: A Case Report

Delusional infestation is an aspecific psychiatric condition manifested either as a primary psychotic disorder or a secondary disorder induced by a wide range of very different medical conditions. Both primary and secondary delusional infestations seem to respond to typical and atypical antipsychotics. The latter are considered the first-line treatment although the use of second-generation antipsychotics featuring a higher metabolic, cardiovascular, and renal tolerability is preferable in secondary cases, which often occur in patients with multiple, severe medical conditions. We report a case of a 72-year-old patient affected by delusional infestation associated with severe renal failure, metabolic syndrome, hypertensive cardiopathy, and chronic cerebrovascular disease

Alexithymia in eating disorders: therapeutic implications

A high percentage of individuals affected by eating disorders (ED) achieve incomplete recovery following treatment. In an attempt to improve treatment outcome, it is crucial that predictors of outcome are identified, and personalized care approaches established in line with new treatment targets, thus facilitating patient access to evidence-based treatments. Among the psychological factors proposed as predictors of outcome in ED, alexithymia is of outstanding interest. The objective of this paper is to undertake a systematic review of the literature relating to alexithymia, specifically in terms of the implications for treatment of ED. In particular, issues concerning the role of alexithymia as a predictor of outcome and as a factor to be taken into account in the choice of treatment will be addressed. The effect of treatments on alexithymia will also be considered. A search of all relevant literature published in English using PubMed, PsycINFO, and Scopus databases was carried out on the basis of the following keywords: alexithymia, anorexia nervosa, bulimia nervosa, eating disorders, and treatment; no time limits were imposed. Despite the clinical relevance of alexithymia, the number of studies published on the above cited aspects is somewhat limited, and these studies are largely heterogeneous and feature significant methodological weaknesses. Overall, data currently available mostly correlate higher levels of alexithymia with a less favorable outcome in ED. Accordingly, alexithymia is seen as a relevant treatment target with the aim of achieving recovery of these patients. Treatments focusing on improving alexithymic traits, and specifically those targeting emotions, seem to show greater efficacy, although alexithymia levels often remain high even after specific treatment. Further investigations are needed to overcome the methodological limitations of previous studies, to understand the actual impact of alexithymia on ED outcome, and to allow more precise implications for treatment to be drawn. Additional research should also be undertaken to specify which of the alexithymic dimensions are specifically relevant to the course and outcome of ED, and to identify treatment protocols producing a significantly greater efficacy in ED patients with relevant alexithymic traits

The Impact of Alexithymia on Treatment Response in Psychiatric Disorders: A Systematic Review

Treatment of psychiatric disorders relies heavily on a trial and error approach, often prolonging the time required to obtain symptomatic improvements. The identification of reliable predictors of treatment response is instrumental to enact an individualized approach. Alexithymia represents a personality trait reflecting an intrinsic difficulty in recognizing the emotional components of subjective experiences. Thus, its modulating role on treatment outcome has gathered substantial attention during the past years. In the present paper, we aimed at exploring the available evidence for Alexithymia role in influencing the treatment outcome on a wide range of psychiatric conditions by means of a systematic review

Delirium in COVID patients: recommendations for assessment and treatment

COVID-19 patients, particularly those admitted to an Intensive Care Unit, are at high risk of Delirium due to the frequently observed concomitant presence of a series of factors which, taken together, constitute an increased risk factor. Factors thought to play a key role include: a direct action of the virus and state of inflammation on the Central Nervous System; secondary effects of organ failure; effect of sedative treatment; prolonged exposure to mechanical ventilation; prolonged immobilisation; environmental factors including social isolation and restricted interaction with relatives and healthcare operators. Bearing in mind the potential impact of delirium on clinical outcome, with an increased risk of death, appropriate prevention and management of this condition, particularly complex in COVID patients due to the frequently observed concomitant presence of numerous predisposing and precipitating factors, is fundamental

Pharmacokinetic Markers of Clinical Outcomes in Severe Mental Illness: A Systematic Review

The term severe mental illness (SMI) encompasses those psychiatric disorders exerting the highest clinical burden and socio-economic impact on the affected individuals and their communities. Pharmacogenomic (PGx) approaches hold great promise in personalizing treatment selection and clinical outcomes, possibly reducing the burden of SMI. Here, we sought to review the literature in the field, focusing on PGx testing and particularly on pharmacokinetic markers. We performed a systematic review on PUBMED/Medline, Web of Science, and Scopus. The last search was performed on the 17 September 2022, and further augmented with a comprehensive pearl-growing strategy. In total, 1979 records were screened, and after duplicate removal, 587 unique records were screened by at least 2 independent reviewers. Ultimately, forty-two articles were included in the qualitative analysis, eleven randomized controlled trials and thirty-one nonrandomized studies. The observed lack of standardization in PGx tests, population selection, and tested outcomes limit the overall interpretation of the available evidence. A growing body of evidence suggests that PGx testing might be cost-effective in specific settings and may modestly improve clinical outcomes. More efforts need to be directed toward improving PGx standardization, knowledge for all stakeholders, and clinical practice guidelines for screening recommendations

Pharmacological Treatment of Bipolar Depression: A Review of Observational Studies

The persistence of depressive morbidity is frequent in bipolar disorder, and the pharmacological management of this symptomatology often lacks effectiveness. This systematic review aimed to summarize the results of the naturalistic observational studies on the pharmacological treatment of bipolar depression published through April 2022. The certainty of evidence was evaluated according to the GRADE approach. In sum, 16 studies on anticonvulsants, 20 on atypical antipsychotics, 2 on lithium, 28 on antidepressants, and 9 on other compounds were found. Lamotrigine, quetiapine, aripiprazole, and ketamine were the most investigated compounds. Overall, the results support the recommendations regarding the effectiveness of lamotrigine and quetiapine. In contrast to the current recommendations, aripiprazole was shown to be effective and generally well tolerated. Additionally, SSRIs were shown to be effective, but, since they were associated with a possibly higher switch risk, they should be used as an adjunctive therapy to mood stabilizers. Lithium was only studied in two trials but was shown to be effective, although the serum concentrations levels were not associated with clinical response. Finally, ketamine showed divergent response rates with a low certainty of evidence and, so far, unclear long-term effects. Heterogeneity in diagnosis, sample sizes, study designs, reporting of bias, and side effects limited the possibility of a head-to-head comparison

Assessment of the Effects of Edible Microalgae in a Canine Gut Model

Microalgae are a source of bioactive compounds having recently been studied for their possible application as health-promoting ingredients. The aim of the study was to evaluate in an in vitro canine gut model the effects of four microalgae, Arthrospira platensis (AP), Haematococcus pluvialis (HP), Phaeodactylum tricornutum (PT) and Chlorella vulgaris (CV), on some fecal microbial populations and metabolites. The four microalgae were subjected to an in vitro digestion procedure, and subsequently, the digested biomass underwent colonic in vitro fermentation. After 6 h of incubation, PT increased propionate (+36%) and butyrate (+24%), and decreased total BCFA (-47%), isobutyrate (-52%) and isovalerate (-43%) and C. hiranonis (-0.46 log10 copies/75 ng DNA). After 24 h, PT increased propionate (+21%) and isovalerate (+10%), and decreased the abundance of Turicibacter spp. (7.18 vs. 6.69 and 6.56 log10 copies/75 ng DNA for CTRL vs. PT, respectively); moreover, after 24 h, CV decreased C. coccoides (-1.12 log10 copies/75 ng DNA) and Enterococcus spp. (-0.37 log10 copies/75 ng DNA). In conclusion, the microbial saccharolytic activities and the shift in fecal bacterial composition were less pronounced than expected, based on current literature. This study should be considered as a preliminary assessment, and future investigations are required to better understand the role of microalgae in canine nutrition

Long-term motor deficit in brain tumour surgery with preserved intra-operative motor-evoked potentials

Muscle motor-evoked potentials are commonly monitored during brain tumour surgery in motor areas, as these are assumed to reflect the integrity of descending motor pathways, including the corticospinal tract. However, while the loss of muscle motor-evoked potentials at the end of surgery is associated with long-term motor deficits (muscle motor-evoked potential-related deficits), there is increasing evidence that motor deficit can occur despite no change in muscle motor-evoked potentials (muscle motor-evoked potential-unrelated deficits), particularly after surgery of non-primary regions involved in motor control. In this study, we aimed to investigate the incidence of muscle motor-evoked potential-unrelated deficits and to identify the associated brain regions. We retrospectively reviewed 125 consecutive patients who underwent surgery for peri-Rolandic lesions using intra-operative neurophysiological monitoring. Intraoperative changes in muscle motor-evoked potentials were correlated with motor outcome, assessed by the Medical Research Council scale. We performed voxel-lesion-symptom mapping to identify which resected regions were associated with short- and long-term muscle motor-evoked potential-associated motor deficits. Muscle motor-evoked potentials reductions significantly predicted long-term motor deficits. However, in more than half of the patients who experienced long-term deficits (12/22 patients), no muscle motor-evoked potential reduction was reported during surgery. Lesion analysis showed that muscle motor-evoked potential-related long-term motor deficits were associated with direct or ischaemic damage to the corticospinal tract, whereas muscle motor-evoked potential-unrelated deficits occurred when supplementary motor areas were resected in conjunction with dorsal premotor regions and the anterior cingulate. Our results indicate that long-term motor deficits unrelated to the corticospinal tract can occur more often than currently reported. As these deficits cannot be predicted by muscle motor-evoked potentials, a combination of awake and/or novel asleep techniques other than muscle motor-evoked potentials monitoring should be implemented
