Several lines of research support the hypothesis that migraine is a spectrum of illness, with clinical symptoms that vary along a continuum from episodic migraine to chronic migraine. Physiologic changes may result in episodic migraine evolving into chronic migraine over months to years in susceptible individuals. With chronification, headache frequency increases, becoming more disabling and less responsive to therapy. Neurophysiologic and functional imaging research has reported that chronic migraine may be associated with severity-specific metabolic, functional, and structural abnormalities in the brainstem...

Electronic pacemakers have been used in patients with heart rhythm disorders for device-supported pacing. While effective, there are such shortcomings as limited battery life, permanent implantation of catheters, the lack of autonomic neurohumoral responses, and risks of lead dislodging. Here we describe protocols for establishing porcine models of sick sinus syndrome and complete heart block, and the generation of bioartificial pacemaker by delivering a strategically engineered form of hyperpolarization-activated cyclic nucleotide-gated pacemaker channel protein via somatic gene transfer to convert atrial or ventricular muscle cardiomyocytes into nodal-like cells that rhythmically fire action potentials...

OBJECTIVE: Although somatic symptoms are common complaints of patients with major depressive disorder (MDD), their associations with suicide are still unclear. METHODS: A total of 811 MDD outpatients of aged between 18 to 64 years were enrolled nationwide in Korea with the suicidality module of the Mini-International Neuropsychiatric Interview (MINI) and the Depression and Somatic Symptom Scale (DSSS). RESULTS: On stepwise regression analysis, current suicidality scores were most strongly associated with chest pain in men, and neck or shoulder pain in women...

The myeloproliferative neoplasms are a heterogeneous group of clonal disorders characterised by overproduction of mature cells in the peripheral blood, together with an increased risk of thrombosis and progression to acute myeloid leukemia. The majority of patients with Philadelphia-chromosome negative myeloproliferative neoplasms harbour somatic mutations in Janus kinase 2, leading to constitutive activation. Acquired mutations in calreticulin or myeloproliferative leukemia virus oncogene are found in a significant number of patients with essential thrombocythaemia or myelofibrosis, and mutations in numerous epigenetic regulators and spliceosome components are also seen...

Exposure to war and ongoing political violence increases mental health risks among children, especially in terms of posttraumatic stress disorder (PTSD), and depressive or somatic symptoms. However, an exclusive focus on negative functioning can lead to underestimating the coping abilities and natural potential for adjusting to trauma of war-affected children at different developmental phases. Using structural equation modelling, we tested the extent to which data gathered in a predominantly nonclinical sample of Palestinian children (N=1276) living in refugee camps supported a conceptual model in which the relationship between subjective wellbeing and the effects of trauma is mainly top-down in direction...

Human pluripotent stem cells (PSCs) generated from affected blastocysts or from patient-derived somatic cells are an emerging platform for disease modeling and drug discovery. Fragile X syndrome (FXS), the leading cause of inherited intellectual disability, was one of the first disorders modeled in both embryonic stem cells and induced PCSs and can serve as an exemplary case for the utilization of human PSCs in the study of human diseases. Over the past decade, FXS-PSCs have been used to address the fundamental questions regarding the pathophysiology of FXS...

Beginning in 2009, the advent of exome sequencing has contributed significantly towards new discoveries of heritable germline mutations and de novo mutations for rare Mendelian disorders with hitherto unknown genetic aetiologies. Exome sequencing is an efficient tool to identify disease mutations without the need of a multi-generational pedigree. Sequencing a single proband or multiple affected individuals has been shown to be successful in identifying disease mutations, but parents would be required in the case of de novo mutations...

REVIEW
Cara Kraus-Perrotta, Sarita Lagalwar
Spinocerebellar ataxia type 1 (SCA1) is an autosomal dominant neurodegenerative disorder that primarily affects the cerebellum and brainstem. The genetic mutation is an expansion of CAG trinucleotide repeats within the coding region of the ataxin-1 gene, characterizing SCA1 as a polyglutamine expansion disease like Huntington's. As with most polyglutamine expansion diseases, SCA1 follows the rules of genetic anticipation: the larger the expansion, the earlier and more rapid the symptoms. Unlike the majority of polyglutamine expansion diseases, the presence of histidine interruptions within the polyglutamine tract of ataxin-1 protein can prevent or mitigate disease...

OBJECTIVE: A World Health Organization (WHO) field study conducted in five countries assessed proposals for Bodily Stress Syndrome (BSS) and Health Anxiety (HA) for the Primary Health Care Version of ICD-11. BSS requires multiple somatic symptoms not caused by known physical pathology and associated with distress or dysfunction. HA involves persistent, intrusive fears of having an illness or intense preoccupation with and misinterpretation of bodily sensations. This study examined how the proposed descriptions for BSS and HA corresponded to what was observed by working primary care physicians (PCPs) in participating countries, and the relationship of BSS and HA to depressive and anxiety disorders and to disability...

OBJECTIVE: DSM-5 somatic symptom disorder (SSD) could potentially be a highly relevant diagnosis for patients with vertigo and dizziness. The criteria of SSD, particularly the B-criterion with its three components (cognitive, affective, behavioral), have however not yet been investigated in this patient group. METHODS: We evaluated a large sample (n=399) of outpatients presenting in a neurological setting. Physical examinations and a psychometric assessment (SCID-I) were conducted; patients completed self-report questionnaires...

Liver cancer cells can be reprogrammed into induced cancer stem cells (iCSCs) by exogenous expression of the reprogramming transcription factors Oct4, Sox2, Klf4 and c-Myc (OSKM). The nucleosome remodeling and deacetylase (NuRD) complex is essential for reprogramming somatic cells. In this study, we investigated the function of NuRD in the induction of liver CSCs. We showed that suppression of methyl-CpG binding domain protein 3 (MBD3), a core subunit of the NuRD repressor complex, together with OSKM transduction, induces conversion of liver cancer cells into stem-like cells...

Somatic mutations in genes of the PI3K/PTEN/AKT/TSC/mTORC1 signaling pathway cause segmental overgrowth, hamartomas, and malignant tumors. Mosaicism for activating mutations in AKT1 or PIK3CA cause Proteus syndrome and PIK3CA-Related Overgrowth Spectrum, respectively. Postzygotic mutations in PTEN or TSC1/TSC2 cause mosaic forms of PTEN hamartoma tumor syndrome or tuberous sclerosis complex, respectively. Distinct features observed in these mosaic conditions in part reflect differences in embryological timing or tissue type harboring the mutant cells...

AIMS: The globalized economy has stimulated mobility in the labour market in many countries and Denmark has one of the highest rates of mobility between workplaces among the OECD countries. This raises the question of the potential health effects of mobility and the effect of disease on mobility. METHODS: This study was register-based with a longitudinal design using data on the entire Danish population in 1992-2006. The data included mobility between employers and workplaces and seven different diseases based on admissions to hospital and drug prescriptions...

BACKGROUND: Current daily general practice has become increasingly technical and somatically oriented (where attention to patients' feelings is decreased) due to an increase in protocol-based guidelines. Priorities in GP-patient communication have shifted from a focus on listening and empathy to task-oriented communication. AIM: To explore what barriers GPs experience when applying empathy in daily practice, and how these barriers are managed. DESIGN AND SETTING: Thirty Dutch GPs with sufficient heterogeneity in sex, age, type of practice, and rural or urban setting were interviewed...

BACKGROUND: Persistent low-grade immune-inflammatory processes, oxidative and nitrosative stress (O&NS), and hypothalamic-pituitary-adrenal axis activation are integral to the pathophysiology of major depressive disorder (MDD). The microbiome, intestinal compositional changes, and resultant bacterial translocation add a new element to the bidirectional interactions of the gut-brain axis; new evidence implicates these pathways in the patho-aetiology of MDD. In addition, abnormalities in the gut-brain axis are associated with several chronic non-communicable disorders, which frequently co-occur in individuals with MDD, including but not limited to irritable bowel syndrome (IBS), chronic fatigue syndrome (CFS), obesity, and type 2 diabetes mellitus (T2DM)...

Psychosomatic research has advanced over the past decades in dealing with complex biopsychosocial phenomena and may provide new effective modalities of patient care. Among psychosocial variables affecting individual vulnerability, course, and outcome of any medical disease, the role of chronic stress (allostatic load/overload) has emerged as a crucial factor. Assessment strategies include the Diagnostic Criteria for Psychosomatic Research. They are presented here in an updated version based on insights derived from studies carried out so far and encompass allostatic overload, type A behavior, alexithymia, the spectrum of maladaptive illness behavior, demoralization, irritable mood, and somatic symptoms secondary to a psychiatric disorder...

Somatization in children consists of the persistent experience and complaints of somatic distress that cannot be fully explained by a medical diagnosis. Working at the Psychophysiological Department at the University Clinic we are dealing with more than 100 children per year manifesting this kind of disorders. The aim of this article is to summarize some specific characteristics of the somatoform disorder in a group of 243 children, mean age 10.31 (± 2.75) years for both genders, selected randomly. The used psychometric instruments are: CBCL, EPQ for children, and MMPI-201 for mothers...

Somatic symptom disorder (SSD) is a challenging condition to treat with chronic pain, a common and disabling symptom. We present a patient who received electroconvulsive therapy (ECT) for SSD with significant improvement in pain and gastrointestinal symptoms. We also present a brief literature review of similar cases treated with ECT. Preliminary evidence suggests that ECT should be considered for treatment of SSD comorbid with major depressive disorder, when standard treatments fail. Further research is needed to clarify whether ECT can be used for SSD without associated depression...
