Among patients with mood disorders, suicidal thinking, planning, and acts are common, particularly during major depressive episodes or mixed episodes. In this chapter, the epidemiology and aetiology of suicidal behaviour in major depressive disorder and bipolar disorder are outlined, followed by the relevant risk factors, and risk assessment of suicide. Finally, the latest evidence on treatments is discussed from a pharmacological, psychological and physical perspective.

There is no consensus for the concept of treatment-resistant depression (TRD). Although some authors argue considering TRD a depression subtype is not supported by evidence, its impact on the individual and society is clear. This chapter discusses the concept of TRD, presents evidence about its neurobiology, pharmacological interventions, and describes drugs currently under investigation. Among the pharmacological strategies to manage TRD, guidelines include increasing the antidepressant dose, switching to another new antidepressant, combining two or more antidepressants, and augmentation of the current medication. Several new components have been investigated for TRD targeting, for instance, the glutamatergic system, inflammatory system, the opioid system, the cholinergic system, dopaminergic system, and neurotrophin signaling. Finally, machine-learning techniques using clinical and neurobiological data provide promising information about treatment outcomes prediction that could change the current approach to a more personalized one.
Colloid fluids are crystalloid electrolyte solutions with a macromolecule added that binds water by its colloid osmotic pressure. As macromolecules escape the plasma only with difficulty, the resulting plasma volume expansion is strong and lasts many hours. The clinically used colloid fluids include albumin, hydroxyethyl starch, gelatin, and dextran.
The plasma volume expansion shows one-compartment kinetics. Marketed iso-oncotic fluids are usually composed so that the infused volume expands the plasma volume by the infused amount. Exceptions include hyperoncotic variants such as 20% albumin.
The main indication for colloid fluid is as second-line treatment of hemorrhage. Because of inherent allergic properties, crystalloid electrolyte fluids should be used when the hemorrhage is small. A changeover to a colloid should be performed only when the crystalloid volume is so large that adverse effects may ensue. The only other clinical indication is that dextran can be prescribed to improve microcirculatory flow.

Almost all patients admitted to psychiatric intensive care units receive pharmacological interventions and medications are often the major treatment intervention. PICU professional staff need to ensure that medication is used safely. This chapter discusses the common medication used in PCUs, their history, evidence base and adverse effects.
Drugs are a part of everyday life and may be defined as any pharmacologically active substance intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease (1). Whether a drug is a conventional medicine, a herbal remedy, or the caffeine in your coffee, drugs are an integral part of human existence and have been since ancient times. Drugs may be synthetic in origin or naturally derived from plants, animals, or biotechnology. A ‘medicine’ is a drug product containing one or more drugs in a formulation administered for a therapeutic purpose.
The dichotomies of ‘typical/atypical’ or ‘first/second generation’ have been employed for several decades to classify antipsychotics, but justification for their use is not clear. In the current analysis we argue that this classification is flawed from both clinical and pharmacological perspectives. We then consider what approach should ideally be employed in both clinical and research settings.
This chapter introduces the contents of this volume and provides a critical overview of medieval pharmacology with a focus on the Mediterranean from the ninth/tenth century to the fifteenth. It emphasises the importance of drawing evidence from various cultures (Byzantine, Islamicate, Jewish, Latin) and disciplines (history, art history, manuscript studies, and archaeology) in order to discuss topics of broader significance for the global Middle Ages, such as the transfer of medical and pharmacological knowledge. It also shows how our understanding of medieval pharmacology can be significantly expanded by the study of evidence from other areas, such as alchemy, cooking, diplomacy, magic, religion, and philosophy.
The anonymous early medieval compilers of recipe collections in Latin manuscripts are not often thought of as curious about new medical information. While the stereotype of medieval Latin stagnation in medicine has been countered, recipe compilers remain as recyclers of the ancient past. Close analysis of early medieval medical recipes, however, suggests that we should reconsider this view. This chapter focuses on a series of dental recipes found in related medieval adaptations of the medical portions of Pliny’s Natural History which suggests several changes over time, including a growing attention to precision and quantification, the deployment of a diverse range of new ingredients, and a link between claims of efficacy and ingredients identified as coming from Africa, Arabia, and India. These recipes reveal shifting uses for materia medica described in classical sources and provide insight into new ways that medieval medical writers were interpreting and adapting their source materials.
This chapter will discuss a Latin translation of an Arabic text on the pharmacological uses of the individual body parts of animals. De sexaginta animalibus is placed in the context of its original Arabic genre of works on the useful or occult virtues of animals, minerals, and plants. This is the first detailed scholarly treatment of this text, which has been mentioned in passing by other scholars. It argues that it is a translation of a work on the properties of the body parts of animals by the eleventh-century physician ʿUbaydallāh ibn Bukhtīshūʿ, by comparing the text with the manāfiʿ (usefulness) section from an Arabic Ibn Bukhtīshūʿ bestiary. Other issues covered include the copious use of transliterated Arabic terminology, particularly in regard to the names of the numerous animals themselves and confusion in their identification, the order of the animals (which aids identification of partial copies of the manuscript), cited authorities, and ascribed authorship. The chapter also argues for the existence of two recensions of the text in the manuscript tradition, with a comparison of an entry found in both recensions with the Ibn Bukhtīshūʿ text and ʿĪsā ibn ʿAlī’s Book on the Useful Properties of Animal Parts.
This chapter focuses on a selection of recipes included in Byzantine alchemical and pharmacological compendia that are preserved in manuscripts dating between the fourteenth and the fifteenth centuries: MSS Parisinus gr. 2314, Bononiensis 1808, and Vaticanus gr. 1174. These manuscripts represent important case studies that are compared with similar collections, from late antique medical encyclopaedias to Byzantine alchemical writings and Nicholas Myrepsos’ pharmaceutical handbook. Through an in-depth analysis of the contents and the terminology of these works, I track the transformation of their technical vocabulary, focusing on cross-cultural exchanges between the Byzantine, Arabic, and Latin traditions. Byzantine authors and copyists reshaped and ‘updated’ a long-lasting technical tradition deeply rooted in late antique and early Byzantine writings, which continued to be read and commented on during the Palaiolοgan period, when scholars compiled large selections of formulas and prescriptions belonging to different, yet overlapping fields, such as metallurgy, pharmacology, and cuisine.
Building on our understanding of how suicide emerges and for whom in the United States this occurs, we move into discussions of identification of and intervention for those at risk. The chapter begins with a brief overview of screening to identify those at risk of suicide, and the challenges in the research literature. Comprehensive risk assessments that incorporate multiple sources of information remain essential, and there is a potential role for machine learning in this process. We then summarize biologic (e.g., lithium, electroconvulsive therapy) and psychosocial (e.g., safety planning, cognitive behavioral therapy) promising practices in suicide prevention, as well as the potential role of technology (e.g., telehealth, apps) in suicide interventions. We then highlight community-based interventions (e.g., gatekeeper training, lethal means safety) and the evidence supporting them. At the societal level, state and federal efforts have focused on creating safe environments (e.g., legislation to reduce access to means) and providing economic supports that are promising. Given the complexity of suicide, we highlight the potential benefits of multimodal, multilevel intervention programs.

In this chapter, ComB treatment is introduced within the context of various BFRB treatment approaches that have been reported over past decades. Brief descriptions of psychodynamic, pharmacological, and so-called “alternative treatments” are briefly reviewed, but the emphasis is on behavioral treatments like habit reversal training (HRT) and its variants, that have dominated research and clinical reports for a half century. ComB treatment is introduced, with attention to its derivation from the ComB conceptual model, and its focus on sensory, cognitive, affective, motor, and place (environmental) variables as critical for assessment and for the design of individualized treatment. Technical aspects of ComB treatment, such as the identification of BFRB functions, its presumed mechanisms of action, its flexibility in individualizing the application to each client, and potential advantages over other treatment approaches are described.
This chapter argues that women doctors participated in a philosophical tradition of thought in classical antiquity. The widely recognised overlap between medicine and philosophy in ancient Greece means that women with medical expertise were very likely involved in the philosophical aspects of the domain. While no extant writings from women doctors survive, the chapter provides evidence of ancient Greek women’s claims to knowledge as found in the writings of male philosophers and doctors. A picture is reconstructed of expertise not only about the female body and its functions and cycles but also a broader understanding of health, disease, fertility, and their relationship to the natural world. The areas of women’s knowledge covered are: experience of the body, theories of the body, pharmacology and theories of reproduction. It is explained how these count as philosophical and why we must consider these women’s ideas to be a significant part of our intellectual heritage.
Post-traumatic stress disorder is a disabling condition resulting from a range of traumas and affecting many people worldwide. This month's Cochrane Corner review systematically searched and reported findings from 66 randomised controlled trials of pharmacotherapy for PTSD, 54 of which were included in a meta-analysis. Evidence was shown for the benefit of selective serotonin reuptake inhibitors, mirtazapine and amitriptyline in treatment response. This Round the Corner commentary critically appraises the review's findings, concluding that the summative evidence was of poor quality owing to the low number of studies, the high risk of bias and significant heterogeneity.
Ayahuasca (AYA) is a psychotropic plant from South America used for religious purposes by indigenous people of the Amazon. Increasing evidence indicates that AYA may have therapeutic potential in the treatment of mental health disorders like depression – a common life-disrupting, highly recurrent disorder – that is among the leading causes of disability worldwide.
Objectives
The aim of this exploratory study is to gather and assess scientific evidence about clinical effects of AYA in the treatment and symptomatological expression of patients with depression.
Methods
A literature research was conducted on PubMed, starting from the MeSH terms: “Banisteriopsis” and “Depression”. Results corresponding to investigations using AYA, and based on an adult population with depressive disorders, were selected for our analysis.
Results
The research provided 8 results, of which 6 met the defined criteria. Different types of studies with variable samples were considered, including retrospective and prospective observational studies, meta-analysis and a narrative review. Overall, evidence about the use of AYA in depressive disorders is associated to reductions in depression scales, to significant antidepressant effects and in mediating improvement of grief symptoms. AYA administration increased introspection and positive mood, self-acceptance, empathy, openness and potentiated improvements in emotional processing. The underlying potential mechanisms, adverse effects and the current limitations related to its study and use are analysed and discussed.
Conclusions
The use of AYA in depression shows promising results that should be further explored in controlled trials with larger sample sizes, in order to better evaluate its clinical effects, safety profile and related short and long-term effects.
Depression is one of the leading causes of psychiatric disability across the globe because of its high prevalence and chronic, treatment resistant and recurrent nature. Erythropoietin (EPO), well known for its effects on blood cells, has also a key role in neuroprotection and cognitive function.
Objectives
The authors aim to explore the potential of EPO to treat depressive disorders (DD) and related cognitive dysfunction.
Methods
A literature research was conducted on PubMed starting from the MeSH terms: “Erythropoietin” and “Depressive Disorders”. The results selected for our analysis corresponded to investigations using EPO based on an adult population with DD.
Results
The research provided 14 results, of which 9 met the defined criteria. Different types of studies with variable samples were considered, including randomized clinical trials (RCTs) and a systematic review. Overall, despite records of reduction in depression symptomatology and increased quality of life, evidence does not demonstrate statistically significant reductions in depression severity through the use of EPO in the treatment of DD. However, several RCTs examined its effect on cognitive performance, founding effective improvements in memory, verbal recall and recognition. The underlying potential mechanisms and the current limitations in the use of EPO, and of the available studies are analysed and discussed.
Conclusions
Although EPO does not appear to be effective treating depression, it may play a role in improvement of deficits in memory and executive function. Larger RCTs evaluating its potential use are needed, in order to move towards better clinical practice, quality of life and functional reintegration of these patients.
Melatonin is often prescribed to patients experiencing sleep disturbances, which has been linked to elevated risks of suicide. However, it remains to be assessed whether melatonin is associated with suicide and suicide attempts.
Objectives
We aimed to investigate whether individuals in treatment with melatonin had higher rates of suicide and suicide attempt when compared to individuals not in treatment.
Methods
Using longitudinal data on all persons aged 10+ years living in Denmark between 2007-2016 were obtained. Data from the National Prescription Register was used to identify periods of being in treatment with melatonin based on number of tablets and daily defined dose. Suicide and suicide attempt were identified in hospital and cause of death registries.
Results
Among 5,798,923 included individuals, 10,577 (0.18%) were in treatment with melatonin (mean treatment length 50 days). Out of 5,952 individuals who died by suicide, 22 (0.37%) were in melatonin treatment, while 134 (0.53%) out of 25,136 had a first suicide attempt. After adjustment for sex and age-group, people in treatment with melatonin were found to have a higher rate of suicide (IRR: 4.2; 95% CI, 2.7-6.4) and suicide attempt (IRR: 6.7-fold (95% CI, 5.7-7.9) when compared to those not in treatment.
Conclusions
Treatment with melatonin was associated with higher rates of suicide and suicide attempt. The association might be explained through mediators, such as psychiatric comorbidity and sleep disorders. Our findings indicate that attention towards these issues might be warranted.
Benzodiazepines and non-benzodiazepines have been linked to a variety of adverse effects including addiction. Long term use of these drugs has been associated with an increased risk of suicide.
Objectives
We assessed if individuals in treatment with non-benzodiazepine (n-BZD) and benzodiazepine (BZD) had higher rates of suicide when compared to individuals not in treatment with these drugs.
Methods
We utilized a cohort design and national longitudinal data on all individuals aged 10 or above who lived in Denmark between 1995 and 2018. Treatment with either n-BZD or BZD was identified via the Danish National Prescription Registry and suicide deaths were identified in the national cause of death registries.
Results
In a total of 6,494,206 individuals, 10,862 males and 4,214 females died by suicide. Of these, 1,220 (11.2%) males and 792 (18.8%) females had been in treatment with n-BZD, resulting in adjusted IRR for suicide of 4.2 (95% CI, 4.0 – 4.5) and 3.4 (95% CI, 3.1 – 3.7) for males and females, respectively, when compared to those not in treatment. In all, 529 (4.8%) males and 395 (9.3%) females who died by suicide had been in treatment with BZD. The IRRs for suicide were 2.4 (95% CI, 2.2 – 2.6) and 2.5 (95% CI, 2.3 – 2.8) for males and females, respectively, and compared to those not in treatment.
Conclusions
In this study we find that those in treatment experienced higher suicide rates than those not in treatment, this persisted when also adjusting for a large variety of covariates.
Drug discovery and development is a long and arduous process and is particularly challenging for Alzheimer’s disease given the incomplete understanding of molecular mechanisms, variability in clinical presentation, relatively slow disease progression, and heterogeneous patient population. The lack of predictive preclinical models combined with the long and expensive clinical trials raise additional barriers to therapeutic development. Tens of thousands of academic publications identify potential biomarkers, molecular mechanisms, preclinical models, and interventions, yet very few have led to industry-sponsored drug development programs. In this chapter, we will describe one academic program’s approach to bridging the “valley of death.” The Stanford University SPARK Program helps academics advance their projects through the applied science stage of development, reducing the risk to potential industry partners. SPARK uses simple and easily replicated principles to ensure that more academic discoveries find their way to impact patients and to benefit society. Approximately 60% of SPARK projects advance to industry partnerships or directly into university-sponsored clinical trials.
