Assessment of depressive symptoms in deaf persons

Abnormal dynamic functional network connectivity in first-episode, drug-naïve patients with major depressive disorder

Dynamic functional network connectivity (dFNC) could capture temporal features of spontaneous brain activity during MRI scanning, and it might be a powerful tool to examine functional brain network alters in major depressive disorder (MDD). Therefore, this study investigated the changes in temporal properties of dFNC of first-episode, drug-naïve patients with MDD. A total of 48 first-episode, drug-naïve MDD patients and 46 age- and gender-matched healthy controls were recruited in this study. Sliding windows were implied to construct dFNC. We assessed the relationships between altered dFNC temporal properties and depressive symptoms. Receiver operating characteristic (ROC) curve analyses were used to examine the diagnostic performance of these altered temporal properties. The results showed that patients with MDD have more occurrences and spent more time in a weak connection state, but with fewer occurrences and shorter dwell time in a strong connection state. Importantly, the fractional time and mean dwell time of state 2 was negatively correlated with Hamilton Depression Rating Scale (HDRS) scores. ROC curve analysis demonstrated that these temporal properties have great identified power including the fractional time and mean dwell time in state 2, and the AUC is 0.872, 0.837, respectively. The AUC of the combination of fractional time and mean dwell time in state 2 with age, gender is 0.881. Our results indicated the temporal properties of dFNC are altered in first-episode, drug-naïve patients with MDD, and these changes' properties could serve as a potential biomarker in MDD.

Sensory Stimulation Via the Visual, Auditory, Olfactory and Gustatory Systems Can Modulate Mood and Depression

Depression is one of the most common mental disorders, predicted to be the leading cause of disease burden by the next decade. There is great deal of emphasis on the central origin and potential therapeutics of depression whereby the symptomatology of depression has been interpreted and treated as brain generated dysfunctions filtering down to the periphery. This top-down approach has found strong support from clinical work and basic neuroscientific research. Nevertheless, despite great advances in our knowledge of the etiology and therapeutics of depression, success in treatment is still by no means assured.. As a consequence, a wide net has been cast by both clinicians and researchers in search of more efficient therapies for mood disorders. As a complementary view, the present integrative review advocates approaching mood and depression from the opposite perspective: a bottom-up view that starts from the periphery. Specifically, evidence is provided to show that sensory stimulation via the visual, auditory, olfactory and gustatory systems can modulate depression. The review shows how -depending on several parameters- unisensory stimulation via these modalities can ameliorate or aggravate depressive symptoms. Moreover, the review emphasizes the bidirectional relationship between sensory stimulation and depression. Just as peripheral stimulation can modulate depression, depression in turn affects-and in most cases impairs-sensory reception. Furthermore, the review suggests that combined use of multisensory stimulation may have synergistic ameliorative effects on depressive symptoms over and above what has so far been documented for unisensory stimulation.

Altered effective connectivity in sensorimotor cortices is a signature of severity and clinical course in depression

Research into neurobiology of depression primarily focuses on its complex psychological aspects. Here we propose an alternative approach and target sensorimotor alterations—a prominent but often neglected feature of depression. We demonstrated using resting-state functional MRI data and computational modeling that top-down and bottom-up information flow in sensory and motor cortices is altered with increasing depression severity in a way that is consistent with depression symptoms. Depression-associated changes were found to be consistent across sessions, amenable to treatment and of effect size sufficiently large to predict whether somebody has mild or severe depression. These results pave the way for an avenue of research into the neural underpinnings of mental health conditions.

Functional neuroimaging research on depression has traditionally targeted neural networks associated with the psychological aspects of depression. In this study, instead, we focus on alterations of sensorimotor function in depression. We used resting-state functional MRI data and dynamic causal modeling (DCM) to assess the hypothesis that depression is associated with aberrant effective connectivity within and between key regions in the sensorimotor hierarchy. Using hierarchical modeling of between-subject effects in DCM with parametric empirical Bayes we first established the architecture of effective connectivity in sensorimotor cortices. We found that in (interoceptive and exteroceptive) sensory cortices across participants, the backward connections are predominantly inhibitory, whereas the forward connections are mainly excitatory in nature. In motor cortices these parities were reversed. With increasing depression severity, these patterns are depreciated in exteroceptive and motor cortices and augmented in the interoceptive cortex, an observation that speaks to depressive symptomatology. We established the robustness of these results in a leave-one-out cross-validation analysis and by reproducing the main results in a follow-up dataset. Interestingly, with (nonpharmacological) treatment, depression-associated changes in backward and forward effective connectivity partially reverted to group mean levels. Overall, altered effective connectivity in sensorimotor cortices emerges as a promising and quantifiable candidate marker of depression severity and treatment response.

Psychiatric morbidity in individuals with permanent orthopedic disability

BACKGROUND

Individuals with permanent orthopedic disability present with a number of physical and mental health issues. Psychiatric illnesses have been seen more frequently among people with disabilities as compared to normal population.

AIM

To study psychiatric morbidity among people with permanent orthopedic disability.

MATERIALS AND METHODS

This cross-sectional, observational, hospital-based study was conducted at the department of psychiatry of a tertiary care hospital attached to a medical college during January 01, 2018, to December 31, 2018. The study included subjects over the age of 18 years comprising two groups: Group A (n = 50) including consecutive subjects with orthopedic disability and Group B (n = 50) including normal age- and sex-matched controls. Permission was obtained from the institutional ethics committee before the start of the study. Prior informed consent was obtained from all subjects. Sociodemographic variables were recorded, and psychiatric morbidity was screened on Mini International Neuropsychiatric Interview.

RESULTS

62% (n = 31) of subjects in Group A had psychiatric morbidity as compared to Group B (22%, n = 11). Maximum psychiatric morbidity noted among subjects with disability was generalized anxiety disorder (22%, n = 11), followed by major depressive disorder (20%, n = 10) and alcohol dependence (18%, n = 9). Substance dependence was more in Group A (34%, n = 17) as compared to Group B (18%, n = 9). The most common substance dependence was for alcohol (18%, n = 9), followed by opioids (8%, n = 4) and tobacco (6%, n = 3).

CONCLUSION

Psychiatric morbidity including substance dependence is more common among people with orthopedic disability as compared to normal control subjects.

Self-esteem, self-efficacy, self-concept and intimate image diffusion among deaf adolescents: A structural equation model analysis

This study aimed to assess the role of self-esteem, self-efficacy and self-concept on intimate image diffusion among in-school deaf adolescents in Lagos, Nigeria. The theory of planned behaviour served as a framework for the study. Data was collected through structured questionnaire from 276 (male = 39.5%; female = 60.5%) in-school deaf adolescents from five senior secondary (3 integrated and 2 inclusive). Data generated were analysed with IBM SPSS 22 and IBM AMOS 26.0 packages. Mean age of participants was ±16.5, all participants use WhatsApp while 71.7% had Facebook profile. It was observed that all the fit measures of the SEM fell within the acceptable range (χ2 = 104.34, df = 39, χ2/df = 2.67, GFI = 0.92, CFI = 0.91, NFI = 0.93, IFI = 0.91 and RMSEA = 0.54). According to the findings, self-esteem and self-efficacy had a positive and direct relationship with intimate image diffusion while a negative but direct link exists between self-concept and intimate image diffusion among deaf adolescents. Based on the finding, an appropriate recommendation was made.

Analysis on Risk Factors of Depressive Symptoms in Occupational Noise-induced Hearing Loss Patients: A Cross-sectional Study

Objective

The aim of this study was to evaluate the risk factors of depressive symptoms in occupational noise-induced hearing loss (NIHL) patients.

Methods

A total of 106 patients were divided into depressive symptoms (ONHLPD) and without depressive symptoms (non-ONHLPD) according to the Self-rating Depression Scale. Questionnaires and laboratory data were collected and analyzed. Data were analyzed with independent t-test, Wilcoxon test, Pearson correlation analysis and multiple linear regression models.

Results

The prevalence of depressive symptoms was 53.8% in occupational NIHL patients. In ONHLPD, duration of the hearing loss, level of serum cortisol, scores of Pittsburgh Sleep Quality Index and Tinnitus Handicap Inventory were all significantly higher than those of non-ONHLPD.

Conclusion

The prevalence of depressive symptoms was relatively high in occupational NIHL patients. Duration of the hearing loss, sleep quality and tinnitus severity were the risk factors for occupational NHIL patients with depressive symptoms.

Anomalous intrinsic connectivity within and between visual and auditory networks in major depressive disorder

OBJECTIVE

Major depressive disorder (MDD) is a ubiquitous mental illness with heterogeneous symptoms, however, the pathophysiology mechanisms are still not fully understood. Clinical and preclinical studies suggested that depression could cause disturbances in sensory perception systems, disruptions in auditory and visual functions may serve as an essential clinical features underlying MDD.

METHODS

The current study investigated the abnormal intrinsic connectivity within and between visual and auditory networks in 95 MDD patients and 97 age-, gender-, education level-matched healthy controls (HCs) by using resting-state functional magnetic resonance imaging (fMRI). One auditory network (AN) and three visual components including visual component 1 (VC1), VC2, and VC3 were identified by using independent component analysis method based on the fMRI networks during the resting state with the largest spatial correlations, combining with brain regions and specific network templates.

RESULTS

We found that MDD could be characterized by the following disrupted network model relative to HCs: (i) reduced within-network connectivity in the AN, VC2, and VC3; (ii) reduced between-network connectivity between the AN and the VC3. Furthermore, aberrant functional connectivity (FC) within the visual network was linked to the clinical symptoms.

CONCLUSIONS

Overall, our results demonstrated that abnormalities of FC in perception systems including intrinsic visual and auditory networks may explain neurobiological mechanisms underlying MDD and could serve as a potential effective biomarker.

[Deaf patients in psychiatry]

Prelingual deafness has multiple and far reaching consequences for the development of language, cognition and the psychosocial dimension. Almost one of a thousand of the population is affected. Barriers in communication limit access to knowledge and participation in society. The use of sign language connects deaf people socio-culturally. This review shows discrepancies between high prevalence rates of mental health disorders with complex psychiatric challenges and barriers to mental health care. The UN convention on the rights of persons with disabilities obliges to counteract these discrepancies. Services with specialised signing professionals and the use of interpreters can improve access to mental health care.

Sensorimotor modulation of mood and depression: in search of an optimal mode of stimulation

Depression involves a dysfunction in an affective fronto-limbic circuitry including the prefrontal cortices, several limbic structures including the cingulate cortex, the amygdala, and the hippocampus as well as the basal ganglia. A major emphasis of research on the etiology and treatment of mood disorders has been to assess the impact of centrally generated (top-down) processes impacting the affective fronto-limbic circuitry. The present review shows that peripheral (bottom-up) unipolar stimulation via the visual and the auditory modalities as well as by physical exercise modulates mood and depressive symptoms in humans and animals and activates the same central affective neurocircuitry involved in depression. It is proposed that the amygdala serves as a gateway by articulating the mood regulatory sensorimotor stimulation with the central affective circuitry by emotionally labeling and mediating the storage of such emotional events in long-term memory. Since both amelioration and aggravation of mood is shown to be possible by unipolar stimulation, the review suggests that a psychophysical assessment of mood modulation by multimodal stimulation may uncover mood ameliorative synergisms and serve as adjunctive treatment for depression. Thus, the integrative review not only emphasizes the relevance of investigating the optimal levels of mood regulatory sensorimotor stimulation, but also provides a conceptual springboard for related future research.

Deaf persons' english reading levels and associations with epidemiological, educational, and cultural factors

One hundred six Michigan d/Deaf persons, part of a study evaluating how to improve d/Deaf persons' understanding of cancer prevention recommendations, had reading levels determined using the Test of Reading Comprehension, Syntactic Sentences. Respondents averaged 52 years old, 59% female, 84% Caucasian, 58% married, and 75% Deaf community members. The mean Test of Reading Comprehension, Syntactic Sentences score was 6.1 (women: 6.2, men: 6.0). Higher scores were associated with greater income (p = .02), employment (p = .01), education (high school p = .002, some college p < .001), English use (child at home, teacher in school, at home now: all p < .001), a hearing spouse (p = .003), hard of hearing/d/Deaf father (p = .02), losing hearing after age 20 years, believing smoking is bad (p < .001), speaking with and satisfaction with physicians and nurses (p < .001), good communication with (p = .01), and comfort discussing cancer with doctors (p < .001). Lower scores were associated with using American Sign Language with physicians and nurses (.019) and Deaf community membership (p = .02). In multivariate analysis, higher scores were associated with higher income, college degree, and teacher using English. Reading levels of a predominantly Deaf population were low. Higher income, college degree, and teacher using English were associated with higher reading levels.

Mental health of deaf people

Deafness is a heterogeneous condition with far-reaching effects on social, emotional, and cognitive development. Onset before language has been established happens in about seven per 10,000 people. Increased rates of mental health problems are reported in deaf people. Many regard themselves as members of a cultural minority who use sign language. In this Review, we describe discrepancies between a high burden of common mental health disorders and barriers to health care. About a quarter of deaf individuals have additional disabilities and a high probability of complex mental health needs. Research into factors affecting mental health of deaf children shows that early access to effective communication with family members and peers is desirable. Improved access to health and mental health care can be achieved by provision of specialist services with professionals trained to directly communicate with deaf people and with sign-language interpreters.

Interpreting for California’s Insured Deaf or Hard of Hearing Population

Deaf or hard of hearing (DHOH) people experience significant health disparities in the United States; signed language interpretation services may increase their access to health care via health insurance plans. The authors’ objective is to describe signed language interpretation (SLI) services provided by California’s health maintenance organizations (HMOs) to their DHOH members. They conducted a descriptive review of an annual state-administered survey of California HMOs from 2003 through 2008 via retrospective analysis of annual or biennial survey responses to questions regarding SLI services and DHOH members. From 2003 through 2008, California HMOs increased efforts to inform DHOH members of SLI services while using more formal methods to assess the quality of those services. DHOH members were increasingly discouraged from using family members for medical SLI. California’s HMOs have improved efforts to promote and evaluate SLI services for the DHOH community.
