Speech, Language, Hearing, and Otopathology Results From the International Smith-Magenis Syndrome Patient Registry.

PURPOSE: Smith-Magenis syndrome (SMS), a rare, genetically linked complex developmental disorder caused by a deletion or mutation within chromosome 17p11.2, is associated with delays in speech-language development, otopathology, and hearing loss, yet previous studies lack comprehensive descriptions of hearing and communication profiles. Here, analyses of patient registry data expand what is known about speech, language, hearing, and otopathology in SMS. METHOD: International speech-language and hearing registry survey data for 82 individuals with SMS were analyzed using descriptive and inferential statistics. Hearing loss, history of otitis media and pressure equalization (PE) tubes, communication mode, expressive/receptive language, and vocal quality were analyzed for all subjects and subjects grouped by age. Statistical methods included descriptive statistics and Pearson's chi-square tests of independence to test for differences between age groups for each variable of interest. Association analyses included Pearson's correlations. RESULTS: Hearing and otological analyses revealed that 35% of subjects had hearing loss, 66% had a history of otitis media, and 62% had received PE tubes. Speech-language analyses revealed that 60% of subjects communicated using speech, 79% began speaking words at/after 24 months of age, 92% combined words at/after 36 months, and 41% used sign language before speech. There was a significant association between the age that first words were spoken and the age that PE tubes were first placed. Communication strengths noted in more than 40% of subjects included social interest, humor, and memory for people, past events, and/or facts. CONCLUSIONS: Significant delays and impairment in speech-language were common, but the majority of those with SMS communicated using speech by age 6 years. Age was a significant factor for some aspects of hearing loss and communication. Neither hearing loss nor otitis media exacerbated language impairment. These results confirm and extend previous findings about the nature of speech, language, hearing, and otopathology in those with SMS.

The Effect of Rating Method on Reliability of Judgments of Strain Across Populations.

PURPOSE: Variability in auditory-perceptual ratings of voice limits their utility, with the poorest reliability often noted for vocal strain. The purpose of this study was to determine whether an experimental method, called visual sort and rate (VSR), promoted stronger rater reliability than visual analog scale (VAS), for ratings of strain in two clinical populations: adductor laryngeal dystonia (ADLD) and vocal hyperfunction (VH). METHOD: Connected speech samples from speakers with ADLD and VH as well as age- and sex-matched controls were selected from a database. Fifteen inexperienced listeners rated strain for two speaker sets (25 ADLD speakers and five controls; 25 VH speakers and five controls) across four rating blocks: VAS-ADLD, VSR-ADLD, VAS-VH, and VSR-VH. For the VAS task, listeners rated each speaker for strain using a vertically oriented 100-mm VAS. For the VSR task, stimuli were distributed into sets of samples with a range of severities in each set. Listeners sorted and ranked samples for strain within each set, and final ratings were captured on a vertically oriented 100-mm VAS. Intrarater reliability (Pearson's r) and interrater variability (mean of the squared differences between a listener's ratings and group mean ratings) were compared across rating methods and populations using two repeated-measures analyses of variance. RESULTS: Intrarater reliability of strain was significantly stronger when listeners used VSR compared to VAS; listeners also showed significantly better intrarater reliability in ADLD than VH. Listeners demonstrated significantly less interrater variability (better reliability) when using VSR compared to VAS. No significant effect of population or interactions was found between listeners for measures of interrater variability. CONCLUSIONS: VSR increases intrarater reliability for ratings of vocal strain in speakers with VH and ADLD. VSR decreases variability of auditory-perceptual judgments of strain between inexperienced listeners in these clinical populations. Future research should determine whether benefits of VSR extend to voice clinicians and/or clinical settings.

Test-Retest Reliability of Behavioral Assays of Feedforward and Feedback Auditory-Motor Control of Voice and Articulation.

PURPOSE: Behavioral assays of feedforward and feedback auditory-motor control of voice and articulation frequently are used to make inferences about underlying neural mechanisms and to study speech development and disorders. However, no studies have examined the test-retest reliability of such measures, which is critical for rigorous study of auditory-motor control. Thus, the purpose of the present study was to assess the reliability of assays of feedforward and feedback control in voice versus articulation domains. METHOD: Twenty-eight participants (14 cisgender women, 12 cisgender men, one transgender man, one transmasculine/nonbinary) who denied any history of speech, hearing, or neurological impairment were measured for responses to predictable versus unexpected auditory feedback perturbations of vocal (fundamental frequency, fo) and articulatory (first formant, F1) acoustic parameters twice, with 3-6 weeks between sessions. Reliability was measured with intraclass correlations. RESULTS: Opposite patterns of reliability were observed for fo and F1; fo reflexive responses showed good reliability and fo adaptive responses showed poor reliability, whereas F1 reflexive responses showed poor reliability and F1 adaptive responses showed moderate reliability. However, a criterion-referenced categorical measurement of fo adaptive responses as typical versus atypical showed substantial test-retest agreement. CONCLUSIONS: Individual responses to some behavioral assays of auditory-motor control of speech should be interpreted with caution, which has implications for several fields of research. Additional research is needed to establish reliable criterion-referenced measures of F1 adaptive responses as well as fo and F1 reflexive responses. Furthermore, the opposite patterns of test-retest reliability observed for voice versus articulation add to growing evidence for differences in underlying neural control mechanisms.

Clinical Cutoff Scores for Acoustic Indices of Vocal Hyperfunction That Combine Relative Fundamental Frequency and Cepstral Peak Prominence.

PURPOSE: This study examined the discriminative ability of acoustic indices of vocal hyperfunction combining smoothed cepstral peak prominence (CPPS) and relative fundamental frequency (RFF). METHOD: Demographic, CPPS, and RFF parameters were entered into logistic regression models trained on two 1:1 case-control groups: individuals with and without nonphonotraumatic vocal hyperfunction (NPVH; n = 360) and phonotraumatic vocal hyperfunction (PVH; n = 240). Equations from the final models were used to predict group membership in two independent test sets (n = 100 each). RESULTS: Both CPPS and RFF parameters significantly improved model fits for NPVH and PVH after accounting for demographics. CPPS explained unique variance beyond RFF in both models. RFF explained unique variance beyond CPPS in the PVH model. Final models included CPPS and RFF offset parameters for both NPVH and PVH; RFF onset parameters were significant only in the PVH model. Area under the receiver operating characteristic curve analysis for the independent test sets revealed acceptable classification for NPVH (72%) and good classification for PVH (86%). CONCLUSIONS: A combination of CPPS and RFF parameters showed better discriminative ability than either measure alone for PVH. Clinical cutoff scores for acoustic indices of vocal hyperfunction are proposed for assessment and screening purposes.

Investigating biological rhythms disruptions across the menstrual cycle in women with comorbid bipolar disorder and premenstrual dysphoric disorder.

We investigated whether women diagnosed with comorbid bipolar disorder (BD) and premenstrual dysphoric disorder (PMDD) experience higher disruptions in biological rhythms in two independent study samples. The first study has a population-based sample of 727 women, including 104 women with PMDD only, 43 women with BD only, 24 women with comorbid PMDD and BD, and 556 women without BD or PMDD (controls). Biological rhythm disruptions were cross-sectionally evaluated using the Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN). The second study enrolled 77 outpatient women who completed prospective assessments at two timepoints: during the mid-follicular and the late-luteal phases of their menstrual cycles, using the BRIAN, and included 19 women with PMDD, 16 with BD, 17 with comorbid PMDD and BD, and 25 controls. In the population-based sample, all the diagnostic groups (BD, PMDD, BDPMDD) presented greater biological rhythm disruption than controls. In addition, women with BD presented greater overall biological rhythms disruption, and greater disruption in sleep, activity, and eating patterns, than women with PMDD. In the outpatient sample study, women with BDPMDD showed greater disruption in the social domain than women with PMDD. In the outpatient sample, women with BDPMDD reported significantly higher disruptions in biological rhythms across both the follicular and the luteal phases of the menstrual cycle. The comorbidity between BD and PMDD may affect biological rhythms beyond the luteal phase of the menstrual cycle. These results support previous literature on the increased illness burden of women diagnosed with comorbid BD and PMDD.

Sensitivity of the Communicative Participation Item Bank for Measuring Patient-Reported Outcomes After Treatment of Unilateral Vocal Fold Immobility.

Importance: The Communicative Participation Item Bank (CPIB) is a patient-reported outcome measure assessing the association between communication disorders and participation in daily communication. To our knowledge, no prior research has examined whether CPIB scores change after treatment of unilateral vocal fold immobility (UVFI). Objective: To compare CPIB scores before and after treatment of UVFI and with patient-defined target treatment outcomes and other common clinical outcomes after UVFI intervention. Design, Setting, and Participants: This single-group case series recruited a convenience sample of community-dwelling patients aged 18 years or older from an urban academic medical center who had a diagnosis of UVFI and planned to receive intervention for UVFI. The study was conducted from March 2014 to March 2019. Exposures: Intervention for UVFI according to clinicians' recommendations. The treatment type was not controlled for this study. Main Outcomes and Measures: Patients' self-reported communicative participation was assessed by obtaining CPIB scores before and after treatment of UVFI, with scores calibrated to the standardized T scale. Pearson correlations between the CPIB general short form and computerized adaptive format, the Voice Handicap Index-10 (VHI-10), and self-rated and clinician-rated voice severity were also evaluated. Results: The sample included 25 participants, of whom 17 (68%) were male, 8 (32%) were female, and the mean (SD) age was 54.9 (17.0) years. Significant changes after treatment were observed in all quantitative outcomes including the primary outcome of the CPIB; the mean T score before treatment was 40.95 (95% CI, 37.49-44.41) and after treatment was 53.23 (95% CI, 48.41-58.04) (mean difference, -13.04 [95% CI, -7.30 to -18.79]; Cohen d, 0.96). The Pearson correlation between the CPIB general short form and computerized adaptive testing scores at pretreatment was r = 0.93 and at posttreatment, r = 0.95. Computerized adaptive testing showed efficiency advantages, with typically 5 to 6 items required for administration compared with 10 items for the short form. The correlation between the CPIB and VHI-10 was moderate before treatment (r = -0.70) and strong after treatment (r = -0.91). Moderate correlations were observed between the CPIB and clinician-rated voice quality before (r = -0.52) and after (r = -0.46) treatment and between CPIB and self-rated voice quality before (r = -0.56) and after (r = -0.62) treatment. Conclusions and Relevance: The results of this case series suggest that the CPIB is relevant for clinical use to assess changes in communicative participation among patients with UVFI before and after they receive treatment.

Perceptions regarding communicative participation in individuals receiving botulinum toxin injections for laryngeal dystonia.

BACKGROUND: Laryngeal dystonia (LD), or spasmodic dysphonia (SD), is a neurological disorder characterized by focal dystonia or involuntary spasms of the laryngeal muscles and associated voice symptoms. It is typically treated with injection of botulinum toxin (BoNT) that weakens the affected muscles. AIMS: The primary purpose of this qualitative study was to explore participants' experience of living with LD and BoNT treatment. The secondary purpose was to examine those experiences as a function of participants' scores on the Communicative Participation Item Bank (CPIB). Results will enhance our understanding of restrictions in communicative participation, assist in planning intervention targeting these restrictions and aid in clinical interpretation of CPIB scores. METHODS & PROCEDURES: Semi-structured interviews using a phenomenological tradition and focusing on BoNT treatment and communicative participation were conducted with 26 people with LD who are on established BoNT treatment regimens. Interviews were recorded, transcribed, coded and analysed inductively. Participants were categorized by CPIB scores into groups ranging from none to extensive participation restrictions. Both self- and expert ratings of voice were obtained. OUTCOMES & RESULTS: Participants with different levels of CPIB scores had different experiences related to communicative participation in the context of BoNT treatment. These differences were organized into the following topics: BoNT and voice; attitudes toward participation; coping strategies; and advice. For all participants except those in the least restricted and most restricted groups, expert ratings of voice did not relate to CPIB scores. CONCLUSIONS & IMPLICATIONS: Although most participants report improved voice with BoNT treatment, many participants experienced lingering restrictions in communicative participation, some to a severe extent. Participants reported coping with these restrictions in many ways; some of these strategies were more successful than others. Those with restricted participation recommended more support for daily life and the emotional toll of LD, as well as support for family members. This support might be offered by speech-language pathologists. WHAT THIS PAPER ADDS: What is already known on the subject Participants with different levels of CPIB scores had different experiences related to communicative participation in the context of BoNT treatment. What this study adds to the existing knowledge Although most participants report improved voice with BoNT treatment, many participants experienced lingering restrictions in communicative participation, some to a severe extent. What are the potential or actual clinical implications of this work? SLP services that take a participation-focused approach to intervention and use multi-factorial approaches to help clients maximize their life participation in the context of LD are well within the SLP scope of practice. SLPs can help clients find and use their optimal voices within the constraints of the dystonia and BoNT effects.

Impaired auditory discrimination and auditory-motor integration in hyperfunctional voice disorders.

Hyperfunctional voice disorders (HVDs) are the most common class of voice disorders, consisting of diagnoses such as vocal fold nodules and muscle tension dysphonia. These speech production disorders result in effort, fatigue, pain, and even complete loss of voice. The mechanisms underlying HVDs are largely unknown. Here, the auditory-motor control of voice fundamental frequency (fo) was examined in 62 speakers with and 62 speakers without HVDs. Due to the high prevalence of HVDs in singers, and the known impacts of singing experience on auditory-motor function, groups were matched for singing experience. Speakers completed three tasks, yielding: (1) auditory discrimination of voice fo; (2) reflexive responses to sudden fo shifts; and (3) adaptive responses to sustained fo shifts. Compared to controls, and regardless of singing experience, individuals with HVDs showed: (1) worse auditory discrimination; (2) comparable reflexive responses; and (3) a greater frequency of atypical adaptive responses. Atypical adaptive responses were associated with poorer auditory discrimination, directly implicating auditory function in this motor disorder. These findings motivate a paradigm shift for understanding development and treatment of HVDs.

The Effect of Visual Sort and Rate Versus Visual Analog Scales on the Reliability of Judgments of Dysphonia.

Purpose The reliability of auditory-perceptual judgments between listeners is a long-standing problem in the assessment of voice disorders. The purpose of this study was to determine whether a relatively novel experimental scaling method, called visual sort and rate (VSR), yielded stronger reliability than the more frequently used method of visual analog scales (VAS) for ratings of overall severity (OS) and breathiness (BR) in speakers with voicedisorders. Method Fifty speech samples were selected from a database of speakers with voice disorders. Twenty-two inexperienced listeners provided ratings of OS or BR in four rating blocks: VSR-OS, VSR-BR, VAS-OS, and VSR-BR. For the VAS task, listeners rated each speaker for BR or OS using a vertically oriented 100-mm VAS. For the VSR task, stimuli were distributed into sets of samples with a range of speaker severities in each set. Listeners sorted and ranked samples for OS or BR within each set, and final ratings were captured on a vertically oriented 100-mm VAS. Interrater variability, defined as the mean of the squared differences between a listener's ratings and group mean ratings, and intrarater reliability (Pearson r) were compared across rating tasks for OS and BR using paired t tests. Results Results showed that listeners had significantly less interrater variability (better reliability) when using VSR methods compared to VAS for judgments of both OS and BR. Intrarater reliability was high across rating tasks and dimensions; however, ratings of BR were significantly more consistent within individual listeners when using VAS than when using VSR. Conclusions VSR is an experimental method that decreases variability of auditory-perceptual judgments between inexperienced listeners when rating speakers with a range of dysphonic severities and disorders. Future research should determine whether a clinically viable tool may be developed based on VSR principles and whether such benefits extend to experienced listeners.

Effect of Noise on Speech Intelligibility and Perceived Listening Effort in Head and Neck Cancer.

Purpose This study (a) examined the effect of different levels of background noise on speech intelligibility and perceived listening effort in speakers with impaired and intact speech following treatment for head and neck cancer (HNC) and (b) determined the relative contribution of speech intelligibility, speaker group, and background noise to a measure of perceived listening effort. Method Ten speakers diagnosed with nasal, oral, or oropharyngeal HNC provided audio recordings of six sentences from the Sentence Intelligibility Test. All speakers were 100% intelligible in quiet: Five speakers with HNC exhibited mild speech imprecisions (speech impairment group), and five speakers with HNC demonstrated intact speech (HNC control group). Speech recordings were presented to 30 inexperienced listeners, who transcribed the sentences and rated perceived listening effort in quiet and two levels (+7 and +5 dB SNR) of background noise. Results Significant Group × Noise interactions were found for speech intelligibility and perceived listening effort. While no differences in speech intelligibility were found between the speaker groups in quiet, the results showed that, as the signal-to-noise ratio decreased, speakers with intact speech (HNC control) performed significantly better (greater intelligibility, less perceived listening effort) than those with speech imprecisions in the two noise conditions. Perceived listening effort was also shown to be associated with decreased speech intelligibility, imprecise speech, and increased background noise. Conclusions Speakers with HNC who are 100% intelligible in quiet but who exhibit some degree of imprecise speech are particularly vulnerable to the effects of increased background noise in comparison to those with intact speech. Results have implications for speech evaluations, counseling, and rehabilitation.

Communicative Participation and Quality of Life in Pretreatment Oral and Oropharyngeal Head and Neck Cancer.

OBJECTIVE: To determine how communicative participation is affected in patients with oral and oropharyngeal head and neck cancers (HNCs) pretreatment and whether communication function predicts HNC-specific quality of life (QOL) before treatment, beyond known demographic, medical, psychosocial, and swallowing predictors. STUDY DESIGN: Cross-sectional study. SETTING: Tertiary care academic medical center. METHODS: Eighty-seven patients with primary oral (40.2%) or oropharyngeal (59.8%) HNC were recruited prior to treatment. T stage, tumor site, and p16 status were extracted from medical records. Demographic and patient-reported measures were obtained. Communicative participation was measured using the Communicative Participation Item Bank (CPIB) General short form. A hierarchical regression analysis included demographic, medical, psychosocial, and functional measures of swallowing and communication as predictors; the University of Washington Quality of Life (UW-QOL v4) composite score was the predicted variable. RESULTS: Median (SD) baseline CPIB scores were 71.0 (11.83); patients with oral cancers reported worse scores. A final sequential hierarchical regression model that included all variables explained 71% of variance in QOL scores. Tumor site, T stage, and p16 status accounted for 28% of variance (P < .001). Perceived depression predicted an additional 28% of the variance (P < .001). Swallowing and communicative participation together predicted an additional 12% of variance (P = .005). Tumor site, perceived depression, swallowing, and communication measures were unique predictors in the final model. Finally, communicative participation uniquely predicted QOL, above and beyond other predictors. CONCLUSION: Pretreatment communication predicted QOL and was negatively affected in some oral and oropharyngeal patients with HNC.

Does the accuracy of case history affect interpretation of videolaryngostroboscopic exams?

OBJECTIVE: To determine the effect of initial diagnostic hypotheses on clinicians' 1) detection and perceived severity of abnormalities, and 2) clinical impressions and treatment recommendations for individuals with and without voice disorders following interpretation of videolaryngostroboscopy (VLS). METHODS: Thirty-two experienced speech-language pathologists and otolaryngologists specializing in voice disorders read case histories prior to interpreting exams. Case histories suggested specific accurate or inaccurate laryngeal diagnoses, or a control scenario that suggested a normal larynx. The effects of the accuracy of case histories on perceived severity of associated visual-perceptual parameters, clinical impressions, and treatment recommendations were examined. RESULTS: Significant increases in perceived severity of posterior laryngeal appearance (P < 0.05) and mucosal wave (P < 0.02) were observed when these abnormalities were suggested by case histories. Overall agreement with clinical impressions improved from 49% to 72% when the case history was consistent with the examination. Case histories (accurate and inaccurate) indicating voice symptoms predicted recommendations for treatment above and beyond that of VLS presentation alone, P < 0.001. CONCLUSION: Case histories suggesting specific abnormalities significantly affected severity ratings for two of three associated visual-perceptual parameters selected as primary outcome measures. Accurate case histories suggesting specific abnormalities increased the probability of detection and perceived severity. Inaccurate case histories led to false-positive findings and failures to detect abnormalities or to interpret them as less severe. Case histories affected visual-perceptual judgments and contributed to decisions about clinical impressions and treatment. LEVEL OF EVIDENCE: 2b Laryngoscope, 130:718-725, 2020.

Resting-state functional connectivity in individuals with bipolar disorder during clinical remission: a systematic review.

BACKGROUND: Bipolar disorder is chronic and debilitating. Studies investigating resting-state functional connectivity in individuals with bipolar disorder may help to inform neurobiological models of illness. METHODS: We conducted a systematic review with the following goals: to summarize the literature on resting-state functional connectivity in bipolar disorder during clinical remission (euthymia) compared with healthy controls; to critically appraise the literature and research gaps; and to propose directions for future research. We searched PubMed/MEDLINE, Embase, PsycINFO, CINAHL and grey literature up to April 2017. RESULTS: Twenty-three studies were included. The most consistent finding was the absence of differences in resting-state functional connectivity of the default mode network (DMN), frontoparietal network (FPN) and salience network (SN) between people with bipolar disorder and controls, using independent component analysis. However, 2 studies in people with bipolar disorder who were positive for psychosis history reported DMN hypoconnectivity. Studies using seed-based analysis largely reported aberrant resting-state functional connectivity with the amygdala, ventrolateral prefrontal cortex, cingulate cortex and medial prefrontal cortex in people with bipolar disorder compared with controls. Few studies used regional homogeneity or amplitude of low-frequency fluctuations. LIMITATIONS: We found heterogeneity in the analysis methods used. CONCLUSION: Stability of the DMN, FPN and SN may reflect a state of remission. Further, DMN hypoconnectivity may reflect a positive history of psychosis in patients with bipolar disorder compared with controls, highlighting a potentially different neural phenotype of psychosis in people with bipolar disorder. Resting-state functional connectivity changes between the amygdala, prefrontal cortex and cingulate cortex may reflect a neural correlate of subthreshold symptoms experienced in bipolar disorder euthymia, the trait-based pathophysiology of bipolar disorder and/or a compensatory mechanism to maintain a state of euthymia.

Relationship between perceived social support and patient-reported communication outcomes across communication disorders: a systematic review.

BACKGROUND: Beyond the severity of voice, speech and language impairments, one potential predictor of communication success across adult populations with communication disorders may be perceived social support: the expectation that others will provide support if needed. Despite the preponderance of intervention approaches that assume a positive relationship between perceived social support and patient-reported communication success, the evidence base for these relationships is limited. AIMS: The aim of this systematic review is to explore relationships between measures of perceived social support and patient-reported communication outcomes in adult populations with communication disorders. METHODS & PROCEDURES: The PRISMA guidelines were followed in the conduct and reporting of this review. Electronic databases including PubMed, PsychINFO and CINAHL were systematically searched up to 19 May 2017. Additional data were obtained for two studies. All the included studies were appraised using the Critical Appraisal Skills Program (CASP) tools. Given the heterogeneous nature of the studies, data synthesis was narrative for the quantitative studies. A meta-ethnographic approach was used to synthesize qualitative data. OUTCOMES & RESULTS: Eight quantitative and four qualitative studies met eligibility criteria. All quantitative studies met eight of eight quality criteria. For the qualitative studies, one study met nine of nine quality criteria; the remaining three studies met three, seven and eight quality criteria. Of the eight included quantitative studies, six independent data sets were used. Results revealed no significant relationships between perceived social support and communication outcomes in three studies (two aphasia with one data set, one Parkinson's disease), while perceived social support was a weak, but significant predictor in two studies (one multiple sclerosis, one head and neck cancer). Three additional studies (two aphasia with one data set; one Parkinson's disease) found that relationships were initially weak, but strengthened over time to become moderate. Results from qualitative studies (one head and neck cancer, two aphasia, one multiple sclerosis) revealed that perceived social support acted as a facilitator, and absent or misguided support acted as a barrier to communication outcomes. Skilful, responsive family members were able to facilitate better quality of communicative interactions, whereas lack of social support, or negative attitudes and behaviours of other people, were barriers. CONCLUSIONS & IMPLICATIONS: While perceived social support may affect communication outcomes in adults with communication disorders, current measures may not adequately capture these constructs. Results have implications for future research and interventions for speech and language therapists.

Role of Psychosocial Factors on Communicative Participation among Survivors of Head and Neck Cancer.

Objective The purpose of this study was to examine the unique contribution of psychosocial factors, including perceived social support, depression, and resilience to communicative participation, among adult survivors of head and neck cancer (HNC). Study Design Cross-sectional. Setting University-based laboratory and speech clinic. Subjects and Methods Adult survivors of HNC who were at least 2 years posttreatment for HNC completed patient-reported outcome measures, including those related to communicative participation and psychosocial function. Multiple linear regression analysis was conducted to predict communicative participation. Self-rated speech severity, cognitive function, laryngectomy status, and time since diagnosis were entered first as a block of variables (block 1), and psychosocial factors were entered second (block 2). Results Eighty-eight adults who were on average 12.2 years post-HNC diagnosis participated. The final regression model predicted 58.2% of the variance in communicative participation (full model R2 = 0.58, P < .001). Self-rated speech severity, cognitive function, laryngectomy status, and time since diagnosis together significantly predicted 46.1% of the variance in block 1. Perceived social support, depression, resilience, and interactions significantly and uniquely predicted 12.1% of the additional variance in block 2. Conclusion For clinicians, psychosocial factors such as perceived depression warrant consideration when counseling patients with HNC about communication outcomes and when designing future studies related to rehabilitation.

Structural and functional changes in the somatosensory cortex in euthymic females with bipolar disorder.

OBJECTIVE: Current evidence from neuroimaging data suggests possible dysfunction of the fronto-striatal-limbic circuits in individuals with bipolar disorder. Somatosensory cortical function has been implicated in emotional recognition, risk-taking and affective responses through sensory modalities. This study investigates anatomy and function of the somatosensory cortex in euthymic bipolar women. METHODS: In total, 68 right-handed euthymic women (bipolar disorder = 32 and healthy controls = 36) between 16 and 45 years of age underwent high-resolution anatomical and functional magnetic resonance imaging during the mid-follicular menstrual phase. The somatosensory cortex was used as a seed region for resting-state functional connectivity analysis. Voxel-based morphometry was used to evaluate somatosensory cortical gray matter volume between groups. RESULTS: We found increased resting-state functional connectivity between the somatosensory cortex and insular cortex, inferior prefrontal gyrus and frontal orbital cortex in euthymic bipolar disorder subjects compared to healthy controls. Voxel-based morphometry analysis showed decreased gray matter in the left somatosensory cortex in the bipolar disorder group. Whole-brain voxel-based morphometry analysis controlled by age did not reveal any additional significant difference between groups. CONCLUSION: This study is the first to date to evaluate anatomy and function of the somatosensory cortex in a well-characterized sample of euthymic bipolar disorder females. Anatomical and functional changes in the somatosensory cortex in this population might contribute to the pathophysiology of bipolar disorder.

Geriatric gambling disorder: challenges in clinical assessment.

To the Editor: The gaming industry is growing rapidly, as is the proportion of older adults aged 65 years or older who participate in gambling (Tse et al., 2012). With casinos tailoring their venues and providing incentives to attract older adults, and with the increasing popularity of "pleasure trips" to casinos organized by retirement homes, plus active promotion of government-operated lotteries in many countries, this trend is likely to continue. Gambling disorder (GD) or "pathological" or "problem" gambling presents a public health concern in the geriatric population. However, ascertainment of its prevalence and diagnostic accuracy have proven challenging. This is largely due to the absence of diagnostic criteria specific to the geriatric age and rating scales validated for use in this population.

Influence of endogenous estradiol, progesterone, allopregnanolone, and dehydroepiandrosterone sulfate on brain resting state functional connectivity across the menstrual cycle.

OBJECTIVE: To [1] study brain resting state functional connectivity (Rs-FC) in a well-characterized sample of healthy women in the mid-follicular and late luteal phases of the menstrual cycle; and [2] examine the correlation between endogenous E2, P, allopregnanolone, and DHEAS and patterns of Rs-FC across the menstrual cycle. DESIGN: We studied the Rs-FC of the default mode network, salience network, meso-paralimbic network, fronto-parietal network, visual network, and sensorimotor network in the mid-follicular and late luteal phases. Serum levels of E2, P, allopregnanolone, and DHEAS were correlated to patterns of functional connectivity. SETTING: University medical center. PATIENT(S): Twenty-five healthy women with regular menstrual cycles. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Functional connectivity of key brain networks at rest and correlations of hormones to Rs-FC in the mid-follcuar and late luteal menstrual phases. RESULT(S): There were no differences in Rs-FC between the mid-follicular and late luteal menstrual phases using either independent component analysis or seed-based analysis. However, specific correlations between each hormone and patterns of functional connectivity were found in both menstrual cycle phases. CONCLUSION(S): It seems that the association between female sex hormones and brain Rs-FC is menstrual cycle phase-dependent. Future studies should examine the cognitive and behavioral correlates of this association in regularly cycling women.

Resting state functional connectivity in women with bipolar disorder during clinical remission.

OBJECTIVES: Periods of euthymia in bipolar disorder (BD) serve as a valuable time to study trait-based pathophysiology. The use of resting state functional connectivity (Rs-FC) can aid in the understanding of BD pathophysiology free of task or mood state biases. The present study investigated two unexplored areas of Rs-FC research in bipolar remission: (i) Rs-FC in women, controlling for the potential influence of premenstrual symptoms, and (ii) the use of both independent component analysis (ICA) and seed-based analysis (SBA) to investigate Rs-FC. METHODS: We investigated Rs-FC of the default mode network, meso-paralimbic network and fronto-parietal network in a sample of 32 euthymic women with BD and 36 age-matched controls during the mid-follicular phase of their menstrual cycle. Rs-FC was assessed with ICA and SBA using the posterior cingulate cortex (PCC), amygdala and dorsolateral prefrontal cortex (dlPFC) as seed points for their respective resting state networks. RESULTS: In BD, compared to controls, SBAs revealed increased coupling between the PCC and the angular gyrus (P=.002, false discovery rate [FDR]-corrected) and between the right dlPFC and the brainstem (P=.03, FDR-corrected). In BD only, PCC-angular gyrus coupling was correlated with anxiety symptoms. Group differences in Rs-FC using ICA did not survive multiple comparisons. CONCLUSIONS: Negative findings from whole-brain ICA Rs-FC may reflect a state of clinical remission in BD. Heightened activation between the PCC and the angular gyrus and between the dlPFC and the brainstem may reflect (i) an abnormal trait integration of affective information during clinical remission and/or (ii) an adaptive compensatory mechanism required for clinical stabilization.

Brain Structure and Function in Women with Comorbid Bipolar and Premenstrual Dysphoric Disorder.

INTRODUCTION: Hormonal fluctuations associated with female reproductive life events may precipitate or worsen affective episodes in women with bipolar disorder (BD). Previous studies have shown that women with BD report higher rates of premenstrual dysphoric disorder (PMDD) than controls. Further, bipolar women who report premenstrual worsening of mood display a worse course of their bipolar illness. Despite this, the neural correlates of comorbid BD and PMDD have not been investigated. METHODOLOGY: Eighty-five [CTRL, n = 25; PMDD, n = 20; BD, n = 21; BD with comorbid PMDD (BDPMDD), n = 19], regularly cycling women, not on hormonal contraception, underwent two MRI scans: during their mid-follicular and late luteal menstrual phases. We investigated resting-state functional connectivity (Rs-FC), cortical thickness, and subcortical volumes of brain regions associated with the pathophysiology of BD and PMDD between groups, in the mid-follicular and late luteal phases of the menstrual cycle. All BD subjects were euthymic for at least 2 months prior to study entry. RESULTS: Women in the BDPMDD group displayed greater disruption in biological rhythms and more subthreshold depressive and anxious symptoms through the menstrual cycle compared to other groups. Rs-FC was increased between the L-hippocampus and R-frontal cortex and decreased between the R-hippocampus and R-premotor cortex in BDPMDD vs. BD (FDR-corrected, p < 0.05). Cortical thickness analysis revealed decreased cortical thickness of the L-pericalcarine, L-superior parietal, R-middle temporal, R-rostral middle frontal, and L-superior frontal, as well as increased cortical thickness of the L-superior temporal gyri in BDPMDD compared to BD. We also found increased left-caudate volume in BDPMDD vs. BD (pCORR < 0.05). CONCLUSION: Women with BD and comorbid PMDD display a distinct clinical and neurobiological phenotype of BD, which suggests differential sensitivity to endogenous hormones.
