This chapter explores the notion of ‘family’ from a philosophical perspective. EU family law recognises that there is such a thing as the family and that it merits special legal protection. Yet, different societies define what counts as a family, and its members, in different ways. The changes in family forms over the last hundred years have also led some to argue that ‘the family’ no longer exists, and, moreover, that it is not special. These arguments are criticised. It is argued that there can be a single concept of ‘the family’ under which different instances fall. The chapter also argues that giving a special legal status to the family requires being able satisfactorily to define what it is and offers a defence of a ‘functional’ definition. It then considers ways in which the family - as defined - might be thought uniquely valuable, critically reviewing appeals to the goods it provides and emphasising the key public good of families in rearing children. The probable impossibility of unifying EU family law does not mean that it is inconsistent to argue that a single concept of family encompasses many different national forms and that the family, in its diversity, continues to merit a special legal status.
The functional roles of ventricular dominance and additional ventricular chamber after Fontan operation are still uncertain. We aim to assess and correlate such anatomical features to late clinical outcomes.
Methods:
Fontan patients undergoing cardiac MRI and cardiopulmonary exercise test between January 2020 and December 2022 were retrospectively reviewed. Clinical, cardiac MRI, and cardiopulmonary exercise test data from the last follow-up were analysed.
Results:
Fifty patients were analysed: left dominance was present in 29 patients (58%, median age 20 years, interquartile range:16–26). At a median follow-up after the Fontan operation was 16 years (interquartile range: 4–42), NYHA classes III and IV was present in 3 patients (6%), 4 (8%) underwent Fontan conversion, 2 (4%) were listed for heart transplantation, and 2 (4%) died. Statistical analysis showed that the additional ventricular chamber was larger (>20 mL/m2) in patients with a right dominant ventricle (p = 0.01), and right dominance was associated with a higher incidence of post-operative low-cardiac output syndrome (p = 0.043). Left ventricular dominance was associated with a better ejection fraction (p = 0.04), less extent of late gadolinium enhancement (p = 0.022), higher metabolic equivalents (p = 0.01), and higher peak oxygen consumption (p = 0.033). A larger additional ventricular chamber was associated with a higher need for post-operative extracorporeal membrane oxygenation support (p = 0.007), but it did not influence functional parameters on cardiac MRI or cardiopulmonary exercise test.
Conclusions:
In Fontan patients, left ventricular dominance correlated to better functional outcomes. Conversely, a larger additional ventricular chamber is more frequent in right ventricular dominance and can negatively affect the early post-Fontan course.
This chapter considers neuroanatomy in terms of the way in which cognitive processes and emotions are organised. Rather than using a strict localisationist approach, with specific cognitive functions being concentrated in particular anatomical areas, emphasis is placed on a more contemporary view of the brain as organised as a series of circuits. The main areas of cognition are considered, namely perception, language, memory, executive function, and attention. Differences between common terms are explained, such as grey and white matter, cortical and subcortical. This chapter also makes use of illustrations.
This chapter uses a case-based approach to describe a few common seizure mimics that may be mistaken for epileptic seizures in critically ill patients. These include tremors, myoclonus, syncope, and functional seizures (psychogenic non-epileptic seizures). Tremors appear as rhythmic or periodic activity but may be differentiated from seizures by the lack of a definite field and stereotyped pattern without evolution. Myoclonus refers to body or limb jerking movements that may be confused with seizures. Myoclonus may be of cortical or subcortical origin. Cortical myoclonus is associated with time-locked epileptic discharges, whereas subcortical myoclonus lacks an epileptic correlate though myogenic artifact may be seen. Convulsive syncope and non-epileptic psychogenic seizures are also described along with their electrographic patterns.

In the absence of defined disease, but also on top of it, functional somatic symptoms indicate subjective distress. They have multidimensional, individual origins and their course is heterogeneous. We do not understand their exact psychophysiological pathways yet, but we know that stressors, attention/expectation and the way we handle them matter a lot. This applies especially to consultation-liaison psychiatry, where patients rarely have one single and simple problem, and there are frequent mismatches between the subjective symptom burden and objective findings.
Management of functional somatic symptoms should be interdisciplinary, mixing diagnostic and therapeutic, physical and psychological techniques. Treatment is based on empathy, psychoeducation, activation and the development of a bio-psycho-social explanatory model. Symptom relief and co-morbid illness can require medication, but passive interventions should only be temporary, with weighted risks and benefits. More severe cases need a multimodal approach or psychotherapy, carefully addressing the embodied self with all its experiences, attitudes and resources.
Increasing interest from stakeholders has brought new focus on risk governance and risk regulation, such as the regulator’s execution of duty and tangible results on safety and environmental protection in oil and gas industry. One recent example, from 2019, is the Office of the Auditor General Norway’s (OAG) investigation of the Petroleum Safety Authority’s (PSA) follow-up on health, safety and the environment in the petroleum industry, where the regulatory regime in Norway resting on functional requirements was questioned. Simplistically speaking, there are two current traditions or main schools in regulatory regimes: use of functional requirements associated with co-regulation and use of normative requirements associated with prescriptive regulation. In this paper, we introduce a generic model from an attribute perspective on contrasting, gauging or evaluating the two different regulatory regimes. Furthermore, this approach may explain the controversy regarding the favouring of functional or prescriptive regulatory regimes by the different players in the industry. Our case is based on regulations relating to offshore oil and gas operations, in particular focusing on the Norwegian sector. We use the OAG’s investigation of the PSA and the public reaction as our material because this material is proposed to provide a thorough and valid description of how the effects of the Norwegian regulatory regime are perceived from the outside. We believe that the generic concept presented here is applicable when performing investigations in other industries involved in hazardous activities.
One of the most vexing issues in a busy emergency department is patients with neurologic psychogenic conversion disorders, also known as functional neurologic symptoms or hysteria. To understand and treat these patients requires patience, understanding, composure, knowledge of neuroanatomy and physiology, and a comprehension of human nature. Long experience evaluating patients with neurologic disorders may be the most important factor, and younger emergency physicians may not have this ability fully developed.
Despite understanding its impact on organizational effectiveness, practical guidance on how to train translational team (TT) leaders is lacking. Previously, we developed an evolutionary learning model of TT maturation consisting of three goal-directed phases: (1). team assembly (Formation); (2). conducting research (Knowledge Generation); and (3). dissemination and implementation (Translation). At each phase, the team acquires group-level knowledge, skills, and attitudes (KSAs) that enhance its performance. Noting that the majority of team-emergent KSAs are promoted by leadership behaviors, we examine the SciTS literature to identify the relevant behaviors for each phase. We propose that effective team leadership evolves from a hierarchical, transformational model early in team Formation to a shared, functional leadership model during Translation. We synthesized an integrated model of TT leadership, mapping a generic “functional leadership” taxonomy to relevant leadership behaviors linked to TT performance, creating an evidence-informed Leadership and Skills Enhancement for Research (LASER) training program. Empirical studies indicate that leadership behaviors are stable across time; to enhance leadership skills, ongoing reflection, evaluation, and practice are needed. We provide a comprehensive multi-level evaluation framework for tracking the growth of TT leadership skills. This work provides a framework for assessing and training relevant leadership behaviors for high-performance TTs.
Quasi-neurological problems can be spurious, the product of the mind or emotions. Distinguishing such conditions from coarse brain disease is accomplished by systematic neurologic analysis. Many of these patients are depressed or malingering. Intense emotions may account for other cases. In a given patient more than one of these terms may be applicable.
The aim of the present study is to investigate the brain circuits or networks that underpin diagnostically specific tasks by means of group independent component analysis for FMRI toolbox (GIFT). We hypothesised that there will be neural network patterns of activation and deactivation, which correspond to real-time performance on clinical self-evaluation scales.
Methods
In total, 20 healthy controls (HC) and 22 patients with major depressive episode have been included. All subjects were scanned with functional magnetic resonance imaging (fMRI) with paradigm composed of diagnostic clinical self-assessment depression scale contrasted to neutral scale. The data were processed with group independent component analysis for functional MRI toolbox and statistical parametric mapping.
Results
The results have demonstrated that there exist positively or negatively modulated brain networks during processing of diagnostic specific task questions for depressive disorder. There have also been confirmed differences in the networks processing diagnostic versus off blocks between patients and controls in anterior cingulate cortex and middle frontal gyrus. Diagnostic conditions (depression scale) when contrasted to neutral conditions demonstrate differential activity of right superior frontal gyrus and right middle cingulate cortex in the comparison of patients with HC.
Conclusion
Potential neuroimaging of state-dependent biomarkers has been directly linked with clinical assessment self-evaluation scale, administered as stimuli simultaneously with the fMRI acquisition. It may be regarded as further evidence in support of the convergent capacity of both methods to distinguish groups by means of incremental translational cross-validation.
The chapter lays a roadmap for the Handbook on Shareholder Engagement and Voting. It defines shareholder engagement as shareholders’ involvement with their investee companies, using their shareholder rights and powers, both formal and informal (such as voting rights), to influence corporate affairs inside and outside general meetings of shareholders. The chapter further discusses the Handbook’s overall methodological considerations, that is, a sophisticated functionalist approach, with a combined use of doctrinal and empirical methods. The chapter proceeds to elaborate on the framework of research questions that guide the Handbook’s chapter contributions on 19 jurisdictions around the globe. The framework comprises three groups of questions: general jurisdictional features, legal means of shareholder voting and engagement, as well as shareholder voting and engagement in practice. The chapter concludes with a brief outline of the Handbook’s structure.
Irritable bowel syndrome (IBS) is the most common functional gastrointestinal disorder, affecting about 20% of people worldwide. This complex and multifaceted disorder has been proposed as a system disease involving not only individual systems including the nervous, endocrine, imune, digestive, microbiota and the environment but also the interactions of these systems. The aetiology of IBS is complex and incompletely understood and this disease are frequently associated with a comorbid psychiatric disease. Current treatment is symptom-directed, rather than based on underlying pathophysiological mechanisms.
Objectives
The authors elaborate a narrative literature review to identify the pathophysiology and therapeutic approach of IBS.
Methods
Pubmed databased searched using the therms “psychiatry”, “irritable bowel syndrome” and “treatment”.
Results
The IBS is the most common and best described of the functional bowel disorders, which represents a considerable therapeutic challenge. Studies looked at the efficacy of fibre, antispasmodics and peppermint oil in the treatment of IBS found moderately effectiveness in the treatment of global symptoms. Elimination diets are helpful in improving IBS. There is evidence that a low-FODMAP diet can have a favorable impact on IBS symptoms, especially abdominal pain, bloating and diarrhea with improved irritable bowel syndrome symptoms and quality of life. Among the currently available classes of drugs for the treatment of IBS, antidepressants such as selective serotonin releasing inhibitors and tricyclic antidepressants are useful because of their analgesic properties, independent of their mood-improving effects.
Conclusions
Evidence suggest that antidepressants might be useful for treatment symptom of IBS however further investigation is required.
Frailty is an important geriatric syndrome that is common and commonly missed, and affects more than a third of people over age 85. Frailty is characterized by diminished physiologic reserves and function, leading to decreased capacity to withstand stressors. Frail adults are at a higher risk of dependency, institutionalization, and death. Multiple interventions have been attempted, including physical activity, improving nutrition, and hormonal therapy, but there are no curative interventions for frailty and it is not clear if frailty can be reversed. Several issues have limited the advancement of frailty research and translation into practice, including the lack of consensus regarding the definition of frailty, the proliferation of assessment tools, and the gaps in validated best practice guidance for frail patients. The recognition of frailty, especially in its early stages, offers the possibility of preventing or mitigating adverse clinical outcomes. Older adults who are frail may benefit most from a comprehensive geriatric evaluation to help elucidate a plan of care that is consistent with patient's goals, values, and preferences.
As perhaps the most comprehensive review of non-finiteness so far, Chapter 2 starts by reviewing the mentions of non-finiteness in the early history of English grammar writing (from 1785), then it digs into the studies of non-finiteness in the following theories: morphology-based traditional grammar, typological perspective, form-based generative grammar, meaning-based cognitive grammar, meaning- and form-based systemic functional grammar, semiotic grammar, role and reference grammar, functional discourse grammar, construction grammar and other approaches. A summary of the enlightening views is provided at the end of the chapter.
We investigated the utility of traditional neuropsychological tests in older uneducated/illiterate individuals without dementia to determine the possibility that they are likely not appropriate for this group.
Methods:
We assessed the neuropsychological performance of 1122 older adults [≥65 years old; mean age: 74.03 (SD = 5.46); mean education: 4.76 (SD = 2.5) years; women: n = 714], in the context of the Hellenic Longitudinal Investigation of Aging and Diet (HELIAD), a population-based study conducted in Greece.
Results:
We based our analyses on three groups: high-functioning/cognitively healthy (i.e., without dementia) uneducated/illiterate individuals (n = 80), high-functioning/cognitively healthy educated/literate individuals (n = 932), and low-functioning/cognitively impaired educated/literate individuals (presumably with dementia; n = 110). We used binary regression analyses with Bonferroni correction to investigate whether test performance differentiated uneducated/illiterate from educated/literate individuals. Models were adjusted for age and sex; raw test scores were the predictor variables. The uneducated/illiterate cohort was at a disadvantage relative to the healthy educated/literate group on all variables but verbal memory recognition and consolidation, congruent motor responses, and phonological fluency clustering (p > .002). Moreover, only word list learning immediate and delayed free recall and delayed cued recall differentiated the high-functioning/cognitively healthy uneducated/illiterate from the low-functioning/cognitively impaired educated/literate group, favoring the former (p’s < .002).
Conclusions:
Our findings suggest that only particular verbal memory test variables are fair in determining whether older uneducated/illiterate individuals have functional/cognitive impairment suggestive of a neurodegenerative process. On all other neuropsychological variables, this cohort was at a disadvantage. Therefore, we highlight the need for identifying appropriate methods of assessment for older uneducated/illiterate individuals.
Some patients present with significant subjective cognitive symptoms, sometimes interfering with day-to-day live, that are not compatible with any recognizable psychiatric, neurodegenerative or systemic condition. Recent studies have proposed that these patients can be diagnosed with Conversion Disorder (Subtype Cognitive), also known as Functional Cognitive Disorder (FCD). This is a relatively recent concept, that still lacks consensus.
Objectives
Review the current state of knowledge regarding prevalence, diagnosis criteria, core clinical features and proposed treatment of Functional Cognitive Disorder.
Methods
Bibliographic review of the literature published in English in the last 5 years, in the databases Pubmed, PsycINFO and Cochrane. The keywords used were: Functional Cognitive Disorder; Cognition; Conversion Disorder. A review of the titles and abstracts of the resulting articles was made, and selected according to their relevance to the study.
Results
Ten articles related to prevalence, diagnosis, clinical associations and treatment of Functional Cognitive Disorder were selected, of which two were systematic reviews, three descriptive studies, three cross sectional clinical studies of memory clinics attendants, one cohort prospective study and one article was a case series report.
Conclusions
The prevalence of FCD is estimated between 11.6% and 56% of patients presenting to memory clinics. However, the prevalence of FCD is hindered by the lack of consensus regarding its definition. Recently, Ball et al proposed a definition in line with the DSM-5 definition of Conversion Disorder with emphasis on positive criteria with the identification of positive evidence of internal inconsistency. Treatment discussion is still limited, and the approach is similar to other conversion disorders.
The EEG is poorly sensitive and specific to detect lesions compared to neuroimaging; its practical use is to determine the functional consequence of the lesion. Focal dysfunction (physiologic) may occur without an associated neuroimaging abnormality. Postictal states and hypoperfusion are examples of physiologic dysfunction; these are often reversible (disappear on repeat testing). Focal dysfunction causes disruption of the background architecture (wakefulness and sleep), asymmetric responses on activation procedures, and focal slowing. Severity of the focal dysfunction may be estimated based on the abundance of slowing, attenuation of amplitude, loss of reactivity, and increase of slower frequencies. Sporadic, intermittent, or fluctuating focal slowing that is reactive to external stimulation or endogenous state changes (such as arousal) may indicate physiological dysfunction. Focal intermittent rhythmic (monomorphic) delta activity such as Lateralized rhythmic delta activity (LRDA) specifically indicates epileptogenicity. It should be treated like an epileptic discharge despite the lack of a sharpness. Look for epileptic discharges that may accompany focal slowing. Focal slowing may occur in isolation, bilaterally, or in the setting of diffuse cerebral dysfunction.
The Montreal Cognitive Assessment (MoCA) is routinely used during the early assessment of people after stroke to indicate cognitive effects and inform clinical decision-making.
Aim:
The purpose of this study was to examine the relationship between cognition in the first week post-stroke and personal and instrumental activities of daily skills at 1 month and 3 months post-stroke.
Method:
A prospective cohort study consecutively recruited people admitted to the acute stroke ward. Acute cognitive status was measured using the MoCA within 1 week post-stroke onset. Functional outcomes were measured using the Functional Independence Measure (FIM) and the Australian Modified Lawton’s Instrumental Activities of Daily Living Scale (Lawton’s) at 1 month and 3 months post-stroke.
Results:
Fifty participants with predominantly mild stroke (n = 47) and mean age of 69.8 achieved a mean MoCA score of 23.1. Controlling for age, the MoCA was associated with the overall FIM score at 1 month (P = 0.02). It was nearing significance for the Lawton’s at 1 month (P = 0.06) but was not associated with either outcome at 3 months. A score of less than 23 on the MoCA was indicative of lower scores on both outcomes.
Conclusions:
A low MoCA score within 1 week of stroke may indicate need for support or rehabilitation due to early impacts on personal activities of daily living, but is not associated with poor functional outcomes at 3 months.
Functional movement disorders (FMDs) pose significant diagnostic and management challenges. We aimed to study the socioeconomic and cultural factors, underlying psychopathology and the phenomenology of FMDs in children.
Methods:
The study is a retrospective chart review of 39 children (16 girls and 23 boys) who attended our neurology OPD and the movement disorders clinic at the National Institute of Mental Health and Neurosciences (NIMHANS) between January 2011 and May 2020. The diagnosis of FMD was based on Fahn and Williams criteria and the patients were either diagnosed as “documented” or “clinically established”. All the relevant demographic data including the ethnicity, socioeconomic and cultural background, examination findings, electrophysiological, and other investigations were retrieved from the medical records.
Results:
The mean age at onset was 12.69 ± 3.13 years. Majority of the children were from urban regions (56.41%) and belonging to low socioeconomic status (46.15%). Thirty (76.92%) were found to have a precipitating factor. Myoclonus was the most common phenomenology observed in these patients (30.76%), followed by tremor (20.51%), dystonia (17.94%), and gait abnormality (7.69%). Chorea (5.12%) and tics (2.56%) were uncommon. Tremor (37.5%) and dystonia (18.75%) were more common in girls, whereas myoclonus (39.13%) was more common in boys.
Conclusions:
The symptoms of FMD have great impact on the mental health, social, and academic functioning of children. It is important to identify the precipitating factors and associated psychiatric comorbidities in these children as prompt alleviation of these factors by engaging parents and the child psychiatrist will yield better outcomes.
Piezoelectric Ba0.85Ca0.15Zr0.1Ti0.9O3 (BCZT) has been found to be a competitive lead-free piezoceramic candidate and was prepared by a sol–gel technique due to its small particle size and homogeneous particle size distribution, but the sintering temperature is still quite high in the previous reports. In the present paper, lithium carbonate (Li2CO3) was used as a sintering aid and dopant for the sol–gel-derived piezoceramic powder, to facilitate the sintering process and adjust the densification, the microstructures and functional properties. With the addition of 0.5 wt% Li2CO3 sintered at 1300 °C, a high relative density 96% with piezoelectric coefficient d33 ~447 pC/N, planar coupling coefficient kp ~0.51, and Curie point TC ~98.7 °C was obtained. The way to properly define the critical changing points on temperature-dependent dielectric curves were further discussed. By altering sintering temperature and the amount of dopant, the mutual influence between the microstructures and the functional properties was explained, to further guide shaping BCZT in more complexed connectivities.
