A novel symmetrical split ring resonator (SSRR) based microwave sensor with spurline filters for detecting and characterizing the properties of solid materials has been developed. Due to the weak perturbation in the interaction of material under test (MUT) and planar microwave sensor, spurline filters were embedded to the SSRR microwave sensor which effectively enhanced Q-factor with suppressing the undesired harmonic frequency. The spurline filter structures force the presented sensor to resonate at a fundamental frequency of 2...

Purpose Limited data are available on the survival of patients with breast cancer with preexisting mental illness, and elderly women are of special interest because they experience the highest incidence of breast cancer. Therefore, we compared all-cause and breast cancer-specific mortality for elderly patients with breast cancer with and without mental illness. Methods A retrospective cohort study was conducted by using SEER-Medicare data, including 19,028 women ≥ 68 years of age who were diagnosed with stage I to IIIa breast cancer in the United States from 2005 to 2007...

Background: Severe mental illness occurring abroad is a difficult situation for patients, their families, and for the local medical community. Patients with mental problem are doublely stigmatized due to their mental illness and because they are foreigners in an unfamiliar country. The appropriate treatment is often delayed, while patients are often dealt with in a manner that violates their human rights. Moreover, repatriation - which is vital in this case - is often delayed due to the lack of international protocols for the transportation and treatment of mentally ill travelers...

BACKGROUND: The Zinc finger protein 804A (ZNF804A) is a promising candidate gene for schizophrenia and the broader psychosis phenotype that emerged from genome-wide association studies. It is related to neurodevelopment and associated to severe symptoms of schizophrenia and alterations in brain structure, as well as positive schizotypal personality traits in non-clinical samples. Moreover, a female-specific association has been observed between ZNF804A and schizophrenia. AIM: The present study examined the association of two ZNF804A polymorphisms (rs1344706 and rs7597593) with the positive dimension of schizotypy and psychotic-like experiences in a sample of 808 non-clinical subjects...

Psychotic experiences (PEs), including hallucination- and delusion-like experiences, are robustly associated with self-injurious thoughts and behaviours (SITB) in the general population. However, it remains unclear as to why there is an association. The purpose of this systematic review was to elucidate the role of other factors that influence the association between PEs and SITB and, in doing so, highlight potential mechanisms underlying the relationship. A search of electronic international databases was undertaken, including PubMed, PsycINFO and EMBASE, and eligible studies were grouped according to seven confounder categories: sociodemographics, mental disorders, alcohol and substance use, environmental, psychological, intervention and family history/genetic factors...

INTRODUCTION: Psychosis is one of the common non-motor symptoms of PD, which substantially worsens the quality of life. Hence, it is important to identify factors that are associated with early onset of psychosis in PD. In order to identify those factors, the current study aims to compare various demographic and clinical features of PD patients with early and late onset psychosis. METHODOLOGY: In this prospective case-control study, 51 consecutive patients with PD having psychosis (PDP) were recruited...

Almost 40% of postpartum psychiatric hospital admissions are brief, lasting 72h or less. We aimed to identify unique subgroups of women within this group to inform better intervention. All women in Ontario, Canada with a brief postpartum psychiatric admission (≤ 72h) (2007-2012)(N = 631) were studied using latent class analysis. We identified distinct subtypes of women and compared women within each subtype on post-discharge mental health indicators: physician visits, emergency department (ED) visits and readmissions...

Depressive episodes or symptoms occur frequently in patients with schizophrenia and may have far-reaching consequences. Despite the high prevalence rate and clinical relevance of this comorbidity, knowledge about treatment options is still limited. The aim of this review is to provide an overview of the literature concerning treatment options for depressive episodes or symptoms in schizophrenia. Based on the current evidence, we present a stepwise treatment approach. The first step is to evaluate the current antipsychotic treatment of psychotic symptoms and consider lowering the dosage, since increased blockade of the dopamine D2 receptors may be associated with a worse subjective sense of well-being and dysphoria...

BACKGROUND: Neuropsychiatric symptoms (NPS), such as depression, apathy, agitation, and psychotic symptoms are common in mild cognitive impairment (MCI) and dementia in Alzheimer's disease (AD). Subgroups of NPS have been reported. Yet the relationship of NPS and their subgroups to different stages of cognitive impairment is unclear. Most previous studies are based on small sample sizes and show conflicting results. We sought to examine the frequency of NPS and their subgroups in MCI and different stages of dementia in AD...

BACKGROUND: Generalized tonic-clonic seizures (GTCS) frequently lead to emergency inpatient referrals. Laboratory blood values are routinely performed on admission to detect underlying causes and metabolic or cardiac complications. Our goal was to assess the nature and frequency of complications occurring in association with GTCS. METHODS: We retrospectively extracted data from emergency protocols and discharge letters of adult patients admitted to the Department of Epileptology between 01/2010 and 06/2015...

Dopamine supersensitivity psychosis (DSP) is observed in patients with schizophrenia under antipsychotic treatment, and it is characterized by rebound psychosis, an uncontrollable psychotic episode following a stable state and tardive dyskinesia. DSP, first described in patients taking typical antipsychotics in the late 1970s, sometimes appears even in patients who are treated with current atypical antipsychotics. It was recently demonstrated that DSP can have a negative impact on the long-term prognosis of schizophrenia patients and that DSP could be involved in the etiology of some cases of treatment-resistant schizophrenia...

OBJECTIVE: To assess the main predictors for repetition of suicidal behaviour among women. METHODS: This cross-sectional study was conducted at Loghman Hakim Hospital, Tehran, Iran, in 2014, and comprised women patients. The patients were divided into two groups, i.e. women repeating suicide and women without repeating suicide. Data was collected through a checklist and then analysed with SPSS 20. RESULTS: Of the 300 women, 121(40.3%) repeated suicide and 179(59...

The timing of thoughts and perceptions plays an essential role in belief formation. Just as people can experience in-the-moment perceptual illusions, however, they can also be deceived about how events unfold in time. Here, we consider how a particular type of temporal distortion, in which the apparent future influences "earlier" events in conscious awareness, might affect people's most fundamental beliefs about themselves and the world. Making use of a task that has been shown to elicit such reversals in the temporal experience of prediction and observation, we find that people who are more prone to think that they predicted an event that they actually already observed are also more likely to report holding delusion-like beliefs...

BACKGROUND: Few studies have addressed the relationship between dementia and crime. We conducted a study of persons who got a primary or secondary diagnosis of dementia or cognitive disorder in a forensic psychiatric examination. METHODS: In Sweden, annually about 500 forensic psychiatric examinations are carried out. All cases from 2008 to 2010 with the diagnoses dementia or cognitive disorder were selected from the database of the Swedish National Board of Forensic Medicine...

Psychological and psychiatric dysfunction is a major problem in a substantial proportion of young adults with Down syndrome. Some patients develop psychiatric issues, such as depressive, obsessive-compulsive, or psychotic-like disorders, in their late adolescence or young adulthood. Furthermore, these individuals may experience moderate to severe emotional and psychological distress. Development of a psychosocial treatment to address these issues is needed in addition to psychotropic medication. The current study reports two cases of young adults with Down syndrome, who presented psychiatric symptoms and marked disruption in their daily lives...

BACKGROUND: Long-acting antipsychotic therapy may be best suited for patients in the early stage of schizophrenia, when the most can be done before disease progression associated with poor adherence occurs. We explored the patterns of use of once-monthly paliperidone palmitate (PP1M), concomitant medication use, hospitalization, and clinical outcomes of adult, newly diagnosed patients with schizophrenia receiving continuous treatment with PP1M for at least 12 months. METHODS: This was an international, multicenter, exploratory, retrospective chart review of medical records of adult patients who were newly diagnosed (not more than 1 year before initiation of PP1M treatment) with schizophrenia and who had received continuous treatment with PP1M for ≥12 months in naturalistic clinical settings...

Interpersonal sensitivity defines feelings of inner-fragility in the presence of others due to the expectation of criticism or rejection. Interpersonal sensitivity was found to be related to attenuated positive psychotic symptom during the prodromal phase of psychosis. The aims of this study were to examine if high level of interpersonal sensitivity at baseline are associated with the persistence of attenuated positive psychotic symptoms and general psychopathology at 18-month follow-up. A sample of 85 help-seeking individuals (mean age = 16...
