Body listening in the link between symptoms and self-care management in cardiovascular disease: A cross-sectional correlational descriptive study.

OBJECTIVE: The aim of this study was to quantify relationships among symptoms, interoceptive sensibility (i.e. the conscious level of sensing, interpreting and integrating signals from the body), and self-care management behaviors (i.e. the response to symptoms when they occur) among adults with cardiovascular disease. We hypothesized that better interoceptive sensibility would increase the positive behavior-driving effects of symptoms on self-care management. METHODS: Adult patients with cardiovascular disease who experienced recent symptoms were recruited to participate in this cross-sectional correlational descriptive study. Patient-Reported Outcomes Measurement Information System measures were used to capture dyspnea, pain interference, fatigue, sleep disturbances, nausea and vomiting, anxiety and depressive symptoms. Interoceptive sensibility was measured using the Multidimensional Assessment of Interoceptive Awareness Version 2. The Self-Care of Chronic Illness Inventory was used to measure self-care management. Network analysis was used to identify domains of interoceptive sensibility that were most central. Linear regression with interaction terms was used to test the moderating effect of interoceptive sensibility on the relationship between symptoms and self-care management. RESULTS: The age of participants in the sample (n = 387) ranged from 18 to 88 years, a slight majority (53.5 %) were female, and a majority were Caucasian (66.4 %) or African American (32.0 %). Hypertension was the most common disorder (n = 238 (61.5 %)), followed by rhythm disorders (n = 124 (32.0 %)), coronary artery disease (n = 94 (24.3 %)), heart failure (n = 89 (23.0 %)), valve disease (n = 69 (17.8 %)), stroke (n = 62 (16.0 %)) and peripheral vascular disease (n = 49 (12.7 %)). Based on network analysis, body listening (i.e. active listening to the body for insights) was the most central interoceptive domain, and distracting (i.e. tendency to ignore or distract oneself from sensations of discomfort) was the least central. Noticing (i.e. greater awareness of body sensations), distracting, and body listening were significant in moderating relationships between dyspnea, sleep disturbances and anxiety and the outcome of self-care management behaviors (all p < 0.001). Better noticing and body listening were associated with better self-care management across symptoms, whereas ignoring or distracting oneself from discomfort was associated with worse self-care management behaviors. CONCLUSION: Among adults with cardiovascular disease, interventions designed to augment the identified interoceptive sensibility domains like body listening, and mitigate the tendency to ignore or distract oneself from discomfort may support adults with cardiovascular disease through the development of future interventions that optimize patient behaviors in response to symptoms when they occur.

A Shifting Paradigm Toward Family-Centered Care in Neuro-Oncology: A Longitudinal Quasi-Experimental Mixed-Methods Feasibility Study.

Family-centered intervention can help families facing illness-related issues. We investigated the feasibility of Family and Network Conversations (FNCs) in high-grade glioma patients and their families. Quasi-experimental feasibility study with longitudinal mixed-methods design. Patients and families were invited to three FNCs over 1 year. They completed questionnaires at four time points and expressed their perspectives on the intervention through telephone interviews. Nurses' perspectives were collected in a focus group. Twenty-one patients and 47 family members were included. On average, patients were 66 years old, mainly male, married, living with caregivers, with unifocal cancer. On average, caregivers were 47 years old, mainly female, being spouses or children of the patient. Quantitative and qualitative data did not always match and expanded each other. Nurse-delivered FNCs holistically addressed families' needs while strengthening family's dialogue and union. Nurses felt empowered, underling that advanced competencies were required. Nurse-delivered FNCs are feasible to provide family-centered care, but they should be tailored to each family's needs.

The Effectiveness of a Motivational Interviewing Intervention on Mutuality Between Patients With Heart Failure and Their Caregivers: A Secondary Outcome Analysis of the MOTIVATE-HF Randomized Controlled Trial.

BACKGROUND: Mutuality, defined as "the positive quality of the relationship between a caregiver and a care receiver", was found to be associated with self-care and caregiver contribution to self-care in heart failure (HF). However, no studies were conducted to evaluate whether motivational interviewing (MI) can improve mutuality in patients with HF and caregivers. OBJECTIVES: The aim of this study was to evaluate the effectiveness of MI on mutuality in HF patient-caregiver dyads. METHODS: This is a secondary outcome analysis of the MOTIVATE-HF randomized controlled trial, the primary aim of which was to evaluate the effect of MI on improving self-care in patients with HF. Participants were randomized into 3 arms: (1) MI for patients only, (2) MI for both patients and caregivers, and (3) standard care. To assess the HF patients' and caregivers' mutuality, the Mutuality Scale was used in its patient and caregiver versions. RESULTS: Patients with HF had a median age of 74 years, and there were more men (58%). Most patients were retired (76.2%). Caregivers had a median age of 55 years and were mostly women (75.5%). Most patients were in New York Heart Association class II (61.9%) and had an ischemic HF etiology (33.6%). The motivational interviews did not show any impact on changes in the patient and caregiver mutuality during the follow-up time (3, 6, 9, and 12 months from baseline). The condition of living together between the patient and the caregiver was significantly associated with better mutuality between the patient and the caregiver. CONCLUSIONS: Motivational interviewing performed by nurses was not effective in improving mutuality in patients with HF and caregivers, but the target variable of the intervention was patient self-care. Stronger effects of MI on mutuality were observed in patients with HF and caregivers who live together. Future studies should target mutuality to see whether MI is really effective.

Cluster analysis of heart failure patients based on their psychological and physical symptoms and predictive analysis of cluster membership.

AIM: Patients with heart failure experience multiple co-occurring symptoms that lower their quality of life and increase hospitalization and mortality rates. So far, no heart failure symptom cluster study recruited patients from community settings or focused on symptoms predicting most clinical outcomes. Considering physical and psychological symptoms together allows understanding how they burden patients in different combinations. Moreover, studies predicting symptom cluster membership using variables other than symptoms are lacking. We aimed to (a) cluster heart failure patients based on physical and psychological symptoms and (b) predict symptom cluster membership using sociodemographic/clinical variables. DESIGN: Secondary analysis of MOTIVATE-HF trial, which recruited 510 heart failure patients from a hospital, an outpatient and a community setting in Italy. METHODS: Cluster analysis was performed based on the two scores of the Hospital Anxiety-Depression scale and two scores of the Heart-Failure Somatic Perception Scale predicting most clinical outcomes. ANOVA and chi-square test were used to compare patients' characteristics among clusters. For the predictive analysis, we split the data into a training set and a test set and trained three classification models on the former to predict patients' symptom cluster membership based on 11 clinical/sociodemographic variables. Permutation analysis investigated which variables best predicted cluster membership. RESULTS: Four clusters were identified based on the intensity and combination of psychological and physical symptoms: mixed distress (high psychological, low physical symptoms), high distress, low distress and moderate distress. Clinical and sociodemographic differences were found among clusters. NYHA-class (New York Heart Association) and sleep quality were the most important variables in predicting symptom cluster membership. CONCLUSIONS: These results can support the development of tailored symptom management intervention and the investigation of symptom clusters' effect on patient outcomes. The promising results of the predictive analysis suggest that such benefits may be obtained even when direct access to symptoms-related data is absent. IMPLICATIONS: These results may be particularly useful to clinicians, patients and researchers because they highlight the importance of addressing clusters of symptoms, instead of individual symptoms, to facilitate symptom detection and management. Knowing which variables best predict symptom cluster membership can allow to obtain such benefits even when direct access to symptoms-data is absent. IMPACT: Four clusters of heart failure patients characterized by different intensity and combination of psychological and physical symptoms were identified. NYHA class and sleep quality appeared important variables in predicting symptom cluster membership. REPORTING METHOD: The authors have adhered to the EQUATOR guidelines STROBE to report observational cross-sectional studies. PATIENT OR PUBLIC CONTRIBUTION: Patients were included only for collecting their data.

The Influence of Caregiver Contribution to Self-care on Symptom Burden in Patients With Heart Failure and the Mediating Role of Patient Self-care: A Longitudinal Mediation Analysis.

BACKGROUND: Patients with heart failure experience high symptom burden, which can be mitigated with adequate self-care. Caregiver contribution to self-care has been theorized to improve patient symptom burden. The mediating role of patient self-care in this relationship has not been tested yet. OBJECTIVES: The aim of this study was to test whether (a) caregiver contribution to self-care influences patient self-care, (b) patient self-care influences symptom burden, and (c) patient self-care mediates the relationship between caregiver contribution to self-care and symptom burden. METHODS: In this study, the authors conducted a secondary analysis of the baseline and 3-month data from the MOTIVATE-HF trial, which enrolled 510 dyads (patient with heart failure and caregiver) in Italy. Multigroup confirmatory factor analysis was used to test measurement invariance. Autoregressive longitudinal path analysis with contemporaneous mediation was used to test our hypotheses. RESULTS: On average, caregivers were 54 years old and mainly female, whereas patients were 72.4 years old and mainly male. Better caregiver contribution to self-care maintenance was associated with better patient self-care maintenance (ß = 0.280, P < .001), which, in turn, was associated with lower symptom burden (ß = -0.280, P < .001). Patient self-care maintenance mediated the effect of caregiver contribution to self-care maintenance on symptom burden (ß = -0.079; 95% bias-corrected bootstrapped confidence interval, -0.130 to -0.043). Better caregiver contribution to self-care management was associated with better patient self-care management (ß = 0.238, P = .006). The model significantly accounted for 37% of the total variance in symptom burden scores (P < .001). CONCLUSIONS: This study expands the situation-specific theory of caregiver contribution to heart failure self-care and provides new evidence on the role of caregiver contribution to self-care and patient self-care on symptom burden in heart failure.

Symptom Patterns in Young Adults with Cancer: An App-Based Study.

OBJECTIVES: To investigate symptom patterns in young adults with cancer using a smartphone-based app. The authors sought to explore symptom frequency and severity, cluster patients based on their symptom severity, investigate the co-occurrence of severe symptoms, and explore the relationship between symptoms and activities. DATA SOURCES: Data were collected, using a mobile app, from 161 young adults with cancer (mean age 25.5 years, 75% female, 59% with solid cancer). Symptom frequency/severity was investigated with descriptive statistics. K-means clustering technique was used to cluster patients based on the average symptom severity. Co-occurrence of severe symptoms was investigated with the association rule technique. The relationship between symptom severity and likelihood of performing a physical/social activity was explored with mixed-effects logistic regression. CONCLUSION: The most frequently reported symptom was mood disturbance, followed by fatigue, which was also the most severe one. Two clusters of patients were identified, experiencing higher and lower severity for all symptoms. Severe appetite disturbances were frequently reported together with severe lack of energy and nausea. Severe lack of energy, either alone or together with mood disturbance, was often reported together with severe fatigue. Higher mood disturbance was associated with lower probability of performing physical and social activities. This study provides new insights into the symptom experience of young adults with cancer. IMPLICATIONS FOR NURSING PRACTICE: Using a symptoms-tracking app may be a valid strategy for healthcare professionals, nurses, and researchers to support patients in symptom monitoring and, consequently, to identify and implement tailored symptom-management strategies.

The Impact of an Intervention to Improve Caregiver Contribution to Heart Failure Self-care on Caregiver Anxiety, Depression, Quality of Life, and Sleep.

BACKGROUND: Better caregiver contribution to self-care in heart failure is associated with better patient outcomes. However, caregiver contribution to self-care is also associated with high anxiety and depression, poor quality of life, and poor sleep in caregivers. It is still unclear whether interventions that encourage caregivers to contribute more to patient self-care might increase caregivers' anxiety and depression and decrease their quality of life and sleep. OBJECTIVE: The aim of this study was to assess the impact of a motivational interview intervention aimed at improving caregiver contribution to self-care in heart failure on caregivers' anxiety, depression, quality of life, and sleep. METHODS: This is a secondary outcome analysis of the MOTIVATE-HF trial. Patients with heart failure and their caregivers were randomized into arm 1 (motivational interview to patients), arm 2 (motivational interview to patients and caregivers), and arm 3 (standard care). Data were collected between June 2014 and October 2018. The article has been prepared following the Consolidated Standards of Reporting Trials checklist. RESULTS: A sample of 510 patient-caregiver dyads was enrolled. Over the year of the study, the levels of anxiety, depression, quality of life, and sleep in caregivers did not significantly change among the 3 arms. CONCLUSIONS: Motivational interview aimed at improving caregiver contribution to self-care does not seem to increase caregiver anxiety and depression, nor decrease their quality of life and sleep. Thus, such an intervention might be safely delivered to caregivers of patients with heart failure, although further studies are needed to confirm our findings.

What is the role of interoception in the symptom experience of people with a chronic condition? A systematic review.

BACKGROUND: Interoception, the ability of the organism to sense, interpret, and regulate signals originating from within the body, plays an important role in how individuals perceive and respond to symptoms. However, there is scarce evidence on the role of interoception in the symptom experience of people with chronic conditions. AIM: To synthesize the role of interoception in the symptom experience of adults with a chronic condition. METHODS: Systematic review. We searched PubMed, Psychinfo, Embase, CINAHL, and Science Citation Index-Expanded. We included primary research (all study designs) addressing our study aim, published between 2013 and 2021, and measuring at least one dimension of interoception. Any chronic condition and any symptom were included. No language limits were applied. Only the adult population was included. RESULTS: We included 18 quantitative studies investigating the relationship between three interoceptive dimensions (i.e., accuracy, sensibility, awareness) and condition-specific symptoms in 8 chronic conditions. People with chronic conditions had lower interoceptive accuracy than healthy controls. Higher interoceptive sensibility was associated with lower symptom severity/frequency. Higher interoceptive accuracy was associated with lower symptom severity/frequency in half of the studies, while the other half reported the opposite. Only one study explored interoceptive awareness. CONCLUSION: Interoceptive accuracy is lower in patients with chronic conditions. Higher interoceptive sensibility is associated with lower symptom severity/frequency, but this relationship is unclear when it comes to interoceptive accuracy and awareness.

Mind Your Heart-II: Protocol for a behavioral randomized controlled trial of mindfulness training to promote self-care in patients with comorbid heart failure and cognitive impairment.

BACKGROUND: Heart failure (HF) self-care is a robust predictor of prognosis in HF patients. Cognitive impairment is a common comorbidity in HF patients and constitutes a major challenge to HF self-care. Mindfulness training (MT) has been shown to improve cognitive function and interoception, two components essential to promoting effective HF self-care. OBJECTIVES: The aims of the Mind Your Heart-II (MYH-II) study are to investigate the effects of MT on HF self-care via changes in cognitive function and interoception in patients with comorbid HF and cognitive impairment, and to study the process by which MT can improve cognitive function via vagal control. We hypothesize that MT will improve cognitive function, interoception, and vagal control, resulting in enhanced HF self-care, compared to control participants. METHODS: MYH-II is a mechanistic parallel phase II behavioral randomized controlled trial. We will enroll 176 English or Spanish-speaking patients with comorbid chronic HF and mild cognitive impairment. Participants will be randomized to either: (1) 8-week phone-delivered MT + Enhanced Usual Care (EUC), or (2) EUC alone. Participants will complete baseline, end-of-treatment (3 months), and follow-up (9 months) assessments. The primary outcome is cognitive function (NIH Toolbox Fluid Cognition Composite Score). Additional key outcomes include: interoception (heartbeat tracking task, Multidimensional Assessment of Interoceptive Awareness), HF self-care (Self-Care of Heart Failure Index v7.2), and vagal control (high-frequency heart rate variability). IMPLICATIONS: If study hypotheses are confirmed, phone-based MT may be a key tool for improving HF self-care, and possibly clinical outcomes, in HF patients with comorbid cognitive impairment.

The cross-cultural adaptation and validation of the Nurse-Nurse Collaboration Scale in Italy.

BACKGROUND AND AIM: Collaboration between colleagues is an essential element of clinical nursing care because it helps to ensure patient safety. This study aimed to evaluate the psychometric properties of the XXX version of the Nurse-Nurse Collaboration Scale (NNCS). The secondary goal of this study was to assess the degree of collaboration between nurses in Italy. METHODS: First, the cultural adaptation of the NNCS tool was performed. The face and content validity of the tool were assessed through the involvement of nursing experts. To test construct validity, a descriptive cross-sectional study was conducted on a sample of 362 nurses. RESULTS: The Italian version of the NNCS was composed of 23 items distributed across five domains. The five-dimensional model showed an adequate model goodness of fit (RMSEA=0.075, CFI=0.883, SRMR=0.072). The NNCS dimension with the highest average score was Professionalism (M=3.10 ± 0.45), while Conflict Management (M=2.14 ± 0.47) exhibited the lowest score. CONCLUSIONS: The Italian version of the NNCS is a valid and reliable tool. More effort should be made to ensure the proper management of conflicts in healthcare environments.

Effectiveness of Motivational Interviewing on contribution to self-care, self-efficacy, and preparedness in caregivers of patients with heart failure: a secondary outcome analysis of the MOTIVATE-HF randomized controlled trial.

AIMS: Caregiver characteristics and behaviours are associated with patients' and caregivers' outcomes. However, there is scarce evidence on interventions aimed at improving caregiver contribution (CC) to patient self-care, caregiver self-efficacy, and caregiver preparedness in heart failure (HF). This study aims to evaluate the effect of Motivational Interviewing (MI) on CC to patient self-care, caregiver self-efficacy, and caregiver preparedness in HF. METHODS AND RESULTS: This is a secondary outcome analysis of MOTIVATE-HF randomized controlled trial. Caregivers of patients with HF were randomized into three arms: Arm 1 (MI for patients), Arm 2 (MI for patients and caregivers), and Arm 3 (standard care). The intervention consisted of one MI session plus three telephone contacts. Data were collected at baseline and after 3, 6, 9, and 12 months. A total of 510 patient and caregiver (median age 54 years, 76% females) dyads were enrolled, 235 caregivers and 238 patients completed the study until 12 months. Caregiver contribution to self-care maintenance and management and caregiver preparedness significantly improved over time, but without significant differences among the three arms. At 9 months, caregiver self-efficacy improved more in Arm 2 than Arm 3 [difference: 8.36, 95% confidence interval (CI) (3.13; 13.59), P = 0.001]. This improvement remained significant also at linear mixed model [ß^ = 1.39, 95% CI (0.02; 2.75), P = 0.046]. CONCLUSION: Motivational Interviewing did not improve CC to patient self-care and caregiver preparedness. However, it increased caregiver self-efficacy, which is known to be a powerful mediator of CC to self-care. REGISTRATION: Clinicaltrials.gov: NCT02894502.

A Motivational Interviewing Intervention Improves Physical Symptoms in Patients with Heart Failure: A Secondary Outcome Analysis of the Motivate-HF Randomized Controlled Trial.

CONTEXT: Heart failure (HF) patients experience high burden of physical symptoms during their disease trajectory. OBJECTIVE: To evaluate the effects of Motivational Interviewing (MI) on the burden of physical symptoms in HF patients. METHODS: We performed a secondary analysis of data from the MOTIVATE-HF randomized controlled trial. A sample of 510 patients (median 74 years, 58% male) and their caregivers (median 55 years, 75.5% female) was randomly allocated to Arm 1 (MI only for patients), Arm 2 (MI for patients and caregivers), and Arm 3 (standard of care). The MI intervention consisted of one face-to-face session plus three telephone calls conducted within two months from enrollment. Symptoms' burden was assessed with the Heart Failure Somatic Perception Scale (HFSPS) with the dimensions of Chest Discomfort, Dyspnea, Early and subtle and Edema. Data were collected at baseline and at 3, 6, 9, and 12 months after enrollment. RESULTS: At 12 months, Chest Discomfort improved in Arms 1 and 2 vs Arm 3 (Δ: -8.13, 95% CI: -14.61; -1.65). Dyspnea improved in Arms 1 and 2 vs Arm 3 both at 9 and 12 months (Δ: -7, 95% CI: -13.18; -0.82 and -6.78, 95% CI: -13.19; -0.38); HFSPS total score improved in Arm 1 and Arm 2 vs Arm 3 at 9 months (Δ: -4.55, 95% CI: -9.05; -0.05). Over 1 year, Chest Discomfort and HFSPS total score in Arm 2 improved compared to Arm 3 (ß= -2.61, 95% CI: -4.21; -1.00, P = 0.0015 and ß=-1.35, 95% CI: -2.50; -0.21, P = 0.02). CONCLUSION: MI reduces the burden of physical HF symptoms, particularly when caregivers are involved in the intervention.

Can hyperventilation test and duration of spontaneous nystagmus help differentiate between vascular and inflammatory aetiology of acute unilateral vestibular deficit?

Objective: To relate clinically the duration of spontaneous nystagmus and hyperventilation-induced nystagmus (HVIN) to vascular or inflammatory aetiology of acute unilateral vestibulopathy observed in a very early stage. Methods: This is a retrospective study on 198 patients with acute unilateral vestibulopathy. Results: In the short-lasting nystagmus group (spontaneous nystagmus < 48 h), mean age and cardiovascular risk were significantly higher; the rates of negative HVIN and paretic HVIN were 41.7% and 58.3%, respectively. In the long-lasting nystagmus group (spontaneous nystagmus > 48 h), mean age and vascular risk were lower; HVIN was absent in 12.6% of the cases, HVIN excitatory patterns were observed in 40.3% of cases and a paretic pattern in 47.1%. Conclusions: A vascular aetiology should be considered the most likely in patients with spontaneous nystagmus < 48 hours: all patients were > 60 years old, cardiovascular risk was higher and HVIN was always absent or paretic. In the group with nystagmus > 48 hours, similarly, data indicate a higher incidence of paretic HVIN in older patients and higher vascular risk, even if the data does not allow us to lean clearly towards one of the two aetiological hypotheses.

The multifaceted role of the Epilepsy Specialist Nurse: Literature review and survey study on patient and medical Staff Perceptions.

BACKGROUND: Epilepsy is frequently accompanied by learning, behavioural and psychological difficulties, therefore the management of this pathology extends far beyond the use of antiepileptic drugs. The specialist-nurse-service provides a multifaceted management. This study adds new points of view on how epilepsy-specialist-nurses work, the benefits they produce and their feedback. OBJECTIVES: The study was conducted to analyse the role of the epilepsy-specialist-nurse, its competencies, its impact on patients and healthcare system and its relevance in patient and medical-staff perceptions, to give new suggestions on how it can be useful in epilepsy teams. METHOD: Literature review to analyse epilepsy-specialist-nurse role; a quantitative research with descriptive approach to examine patients' (11) perceptions using a novel-questionnaire; applied qualitative analysis of medical staff (4) perceptions through semi-structured interviews. RESULTS: The epilepsy-specialist-nurse has the competences to manage the epilepsy-related issues that extend beyond medications. Patients value the ability of specialist-nurses to answer their multifaceted needs, to dedicate them enough time to discuss the impact of epilepsy on everyday-life and their feelings, giving suggestions. Doctors collaborating with specialist-nurses recognize their valuable contribute. Doctors give more information on epilepsy and medication-issues: patients prefer to consult a doctor for these issues. CONCLUSION: The holistic way adopted by specialist-nurses in addressing patients' needs is fundamental to improve patients' health and well-being. Medical and nursing ability to address epilepsy-related issues in a very similar way - in the items analysed - may reveal that specialist-nurses can provide high-quality assistance while achieving cost-savings. It is needed to develop a structured pathway that allows the progression of specialist-nursing, to define a clear job description, and to obtain government recognition.

Translabyrinthine vestibular neurectomy and simultaneous cochlear implant for Ménière's disease.

BACKGROUND: Surgical management of Ménière's disease (MD) is recommended in case of medical and intratympanic treatment failures. Translabyrinthine vestibular nerve section has been considered the gold standard for denervation procedures in order to control vertigo attacks, although at the cost of sacrificing residual hearing. To the best of our knowledge, no work has been published with regard to a group of patients submitted to translabyrinthine vestibular neurectomy and simultaneous cochlear implant for MD. The aim of the present study was to assess the effectiveness of translabyrinthine vestibular nerve section and simultaneous cochlear implant in a prospective study. METHODS: All adult patients (over 18 years of age) with a diagnosis of intractable unilateral definite MD and useless residual hearing function were enrolled after medical and intratympanic treatment failures. Pre- and postoperative otoneurological evaluation concerned: frequency of vertigo attacks, head impulse test and caloric testing, pure tone average and speech perception audiometry in quiet conditions, tinnitus handicap inventory test, functional level scale and rate of vertigo control, dizziness handicap inventory test, and MD patient-oriented severity index. At least 6 months of follow-up were needed to be enrolled in the study. RESULTS: Four patients were included in the study. Translabyrinthine vestibular nerve section and simultaneous cochlear implant seemed to considerably improve the disabling effects of MD, achieving a good control of vestibular symptoms (mean pre/postoperative vertigo attacks per month: 16.5/0), resolving hearing loss (mean pre/postoperative pure tone average in the affected ear: 86.2/32.5 dB), improving the tinnitus (mean pre/postoperative tinnitus handicap inventory test: 77.2/6), and finally increasing the overall quality-of-life parameters. CONCLUSIONS: In our preliminary report, translabyrinthine vestibular nerve section and simultaneous cochlear implant showed encouraging results in order to definitively control both vestibular and cochlear symptoms during the same therapeutic procedure.

Probing Metal Ion Complexation of Ligands with Multiple Metal Binding Sites: The Case of Spiropyrans.

Among known molecular switches, spiropyrans attract considerable interest because of their reversible responsiveness to external stimuli and the deep conformational and electronic changes that characterize the switching process between the two isomeric forms [spiropyran (SP) and merocyanine (MC)]. Metal coordination is one of the most interesting aspects of spiropyrans for its potential in sensing, catalysis, and medicinal chemistry, but little is known about the details surrounding spiropyran-metal ion binding. We investigated the interplay between an N-modified 8-methoxy-6-nitrospiropyran (SP-E), designed to provide appropriate molecular flexibility and a range of competing/collaborative metal binding sites, with Mg2+ , Cu2+ and Zn2+ , which were chosen for their similar coordination geometry preferences while differing in their hard/soft character. The formed molecular complexes were studied by means of UV/Vis, fluorescence, and NMR spectroscopies and mass spectrometry, and the crystal structure of the SP-E-Cu complex was also obtained. The results indicate that the Mg2+ , Zn2+ and Cu2+ complexes have identical coordination stoichiometry. Furthermore, the Mg2+ and Zn2+ complexes display fluorescence properties in solution and visible-light responsiveness. These results provide important spectroscopic and structural information that can serve as a foundation for rational design of spiropyran-based smart materials for metal sensing and scavenging applications.
