Personality characteristics, music-listening, and well-being: a systematic and scoping review.

When researchers and clinicians try to identify appropriate and effective ways to improve well-being among different populations, music is often included in interventions or research projects. The existing literature has consistently reported interactions between the effects of personality traits and music listening. However, the interrelations between individual traits and well-being after music listening are still partially unclear. This systematic review, registered on PROSPERO, investigates the relationship between everyday music listening, individual characteristics - operationalized as stable and transient personality traits - and well-being. Articles were searched on PubMed, Scopus, and Google Scholar, with a final result of 115 records. After eligibility screening, eight studies were included in the review. The results showed that both stable and transient personality traits influence music's effect on well-being. As a result of the scoping review, a theoretical perspective combining the emotional dimension, the principle of emotional congruence, and the dimension of music immersion and well-being was identified. Based on this knowledge, music listening could be systematically introduced into daily routines to improve everyday well-being and prevent or reduce stressful states.

The Effect of COVID-19 on Middle-Aged Adults' Mental Health: A Mixed-Method Case-Control Study on the Moderating Effect of Cognitive Reserve.

The COVID-19 pandemic has increased the vulnerability of adults to mental health effects, and the study of protective factors has become crucial. Cognitive reserve (CR) is a well-known protective factor against cognitive decline and several health factors; however, its protective effect on mental health during the pandemic has been rarely addressed. Thus, this study explored, through a mixed-method design, the effect of CR on perceived distress and PTSD-like symptoms in middle-aged participants who have survived severe COVID-19 and a matched control group. A total of 432 participants filled out self-report measures of CR, PTSD, depression, and anxiety, and were also asked to provide narration about their COVID-19-related experience. COVID-19 significantly affected the chances of reporting different mental health symptoms; levels of CR played a protective role in reducing their severity. Moreover, adults with higher CR seemed to be more realistic, focusing less on positive emotions, and elaborating more on the sense of anxiety when describing their experience: this might be an indication of a lower use of suppression to regulate emotions. Practical implications of these findings and future directions have been also discussed.

A simple and robust nanosystem for photoacoustic imaging of bladder cancer based on α5ß1-targeted gold nanorods.

BACKGROUND: Early detection and removal of bladder cancer in patients is crucial to prevent tumor recurrence and progression. Because current imaging techniques may fail to detect small lesions of in situ carcinomas, patients with bladder cancer often relapse after initial diagnosis, thereby requiring frequent follow-up and treatments. RESULTS: In an attempt to obtain a sensitive and high-resolution imaging modality for bladder cancer, we have developed a photoacoustic imaging approach based on the use of PEGylated gold nanorods (GNRs) as a contrast agent, functionalized with the peptide cyclic [CphgisoDGRG] (Iso4), a selective ligand of α5ß1 integrin expressed by bladder cancer cells. This product (called GNRs@PEG-Iso4) was produced by a simple two-step procedure based on GNRs activation with lipoic acid-polyethyleneglycol(PEG-5KDa)-maleimide and functionalization with peptide Iso4. Biochemical and biological studies showed that GNRs@PEG-Iso4 can efficiently recognize purified integrin α5ß1 and α5ß1-positive bladder cancer cells. GNRs@PEG-Iso4 was stable and did not aggregate in urine or in 5% sodium chloride, or after freeze/thaw cycles or prolonged exposure to 55 °C, and, even more importantly, do not settle after instillation into the bladder. Intravesical instillation of GNRs@PEG-Iso4 into mice bearing orthotopic MB49-Luc bladder tumors, followed by photoacoustic imaging, efficiently detected small cancer lesions. The binding to tumor lesions was competed by a neutralizing anti-α5ß1 integrin antibody; furthermore, no binding was observed to healthy bladders (α5ß1-negative), pointing to a specific targeting mechanism. CONCLUSION: GNRs@PEG-Iso4 represents a simple and robust contrast agent for photoacoustic imaging and diagnosis of small bladder cancer lesions.

Development of trans-Chalcone loaded pectin/casein biodegradable microcapsules: Efficacy improvement in the management of experimental colitis.

Improved therapies for inflammatory bowel diseases are sorely needed. Novel therapeutic agents and the development of controlled release systems for targeted tissue delivery are interesting approaches to overcome these barriers. We investigated the activity of trans-chalcone (T) in acetic acid-induced colitis in mice and developed, characterized, and determined the therapeutic effect of pectin/casein polymer microcapsules containing T (MT) in a colitis mouse model. In vitro, compound release was achieved in simulated intestinal fluid but not in the simulated gastric fluid. In vivo, since T at the dose of 3 mg/kg but not 0.3 mg/kg ameliorated colitis, we next tested the effects of MT at 0.3 mg/kg (non-effective dose). MT, but not free T at 0.3 mg/kg, significantly improved colitis outcomes such as neutrophil recruitment, antioxidant capacity, cytokine production, and NF-kB activation. This translated into reduced macro and microscopic damage in the colon. T release from the microcapsules is mediated by a pH-dependent and pectinase-regulated mechanism that provide controlled and prolonged release of T. Moreover, MT lowered the required dose for T therapeutic effect, indicating that could be a suitable pharmaceutical approach to colitis treatment. This is the first demonstration that T or MT is effective at reducing the signs of colitis.

The relationship between cognitive reserve and the spontaneous use of emotion regulation strategies in older adults: a cross-sectional study.

BACKGROUND: Several studies reported cognitive reserve (CR) as an important factor in promoting healthy aging within a non-clinical aging population. AIMS: The main goal of the present study is to investigate the link between higher levels of CR and more effective emotion regulation. In more detail, we examine the association between a number of CR proxies and the habitual use of two emotion regulation strategies, cognitive reappraisal and emotional suppression. METHODS: Three hundred and ten older adults aged between 60 and 75 (mean = 64.45, SD = 4.37; 69.4% female) joined this cross-sectional study by filling out self-report measures of CR and emotion regulation.² RESULTS: Reappraisal and suppression use were correlated. Practicing different leisure activities constantly over many years, being more original and having a higher education promoted more frequent use of cognitive reappraisal. These CR proxies were also significantly related to suppression use, even though the percentage of variance explained was lower. DISCUSSION AND CONCLUSIONS: Exploring the role played by the cognitive reserve on different emotion regulation techniques can be useful in understanding which variables predict the use of antecedent-focused (reappraisal) or response-focused (suppression) emotion regulation strategies in aging individuals.

Exploring Patients' Trust from a New Perspective. A Text-Analysis Study.

The concept of trust has been extensively studied within the field of medicine. Yet, a list of factors that clearly influence patients' trust is still under debate. Moreover, the methodological approaches found in literature have been reported to be lacking in their assessments and measurements of trust relationships in the medical field although trust between a patient and medical provider has been proven to increase adherence and improve health outcomes. Hence, adding data to this debate and exploring a reliable method to explore the construct of trust is relevant. This study collects new evidence of the most salient indicators of patient trust by using a narrative approach and highlighting the potential of this method in collecting indicators that could be used to build training that aims to increase patients' trust. We used the Linguistic Inquiry and Word Count software for text analysis to examine the spontaneous narrations of episodes of trust and distrust within the doctor-patient relationship with a sample of 82 adult patients. Results demonstrate the role of the emotional aspects of the doctor-patient relationship. Data highlights the importance of doctors' benevolence toward patients, and positive emotions seem to be deeply connected with any experience of trust, which leads patients to feel more secure. Methods are presented to use these insights to construct mechanisms that establish medical trust and allow providers to implement effective interventions.

Quantification of Chromogranin A and Its Fragments in Biological Fluids.

Human chromogranin A (CgA), a 439-residue long neurosecretory protein, can serve as a circulating biomarker for a wide range of neuroendocrine tumors. Increased levels of immunoreactive CgA are also present in the blood of patients with cardiovascular, gastrointestinal, or inflammatory diseases with, in certain cases, important diagnostic and prognostic implications. A growing body of evidence suggest that CgA and various CgA-derived fragments have complex roles in the regulation of cardiovascular system, metabolism, innate immunity, angiogenesis, and tissue repair, sometime with opposite biological effects. For example, while full-length CgA (CgA1-439) inhibits angiogenesis, the CgA1-373 fragment, at certain doses, is proangiogenic. Thus, the selective quantification of CgA and its fragments in the blood of patients (and in other biological fluids) is of great experimental and clinical interest. Here, we describe methods to produce CgA1-439 and CgA1-373 and to develop ELISAs capable of detecting these polypeptides in a very selective manner. The same approach can be used, in principle, also for developing assays for other fragments.

The Role of TNF-α in Alzheimer's Disease: A Narrative Review.

This review analyzes the role of TNF-α and its increase in biological fluids in mild cognitive impairment, and Alzheimer's disease (AD). The potential inhibition of TNF-α with pharmacological strategies paves the way for preventing AD and improving cognitive function in people at risk for dementia. We conducted a narrative review to characterize the evidence in relation to the involvement of TNF-α in AD and its possible therapeutic inhibition. Several studies report that patients with RA and systemic inflammatory diseases treated with TNF-α blocking agents reduce the probability of emerging dementia compared with the general population. Animal model studies also showed interesting results and are discussed. An increasing amount of basic scientific data and clinical studies underscore the importance of inflammatory processes and subsequent glial activation in the pathogenesis of AD. TNF-α targeted therapy is a biologically plausible approach for cognition preservation and further trials are necessary to investigate the potential benefits of therapy in populations at risk of developing AD.

Seizure occurring with retinal laser therapy: a report of the first case with frequency-doubled Nd-YAG / Convulsão durante laserterapia retiniana: relato do primeiro caso com o Nd-YAG de frequência dobrada

ABSTRACT Laser photocoagulation is a safe method for the treatment of retinal disorders. We present a case of a 21-year-old woman with high myopia, retinal detachment in the right eye, and bilateral lattice degeneration. She underwent surgical repair in the right eye followed by bilateral retinal laser therapy. During laser photocoagulation of the left eye, she experienced a generalized tonic-clonic seizure for the first time in her life. She had a positive family history of epilepsy. Neurological examination and brain magnetic resonance imaging findings were normal, but an electroencephalogram revealed epileptogenic discharges, more frequent during photostimulation. She avoided flickering lights during the 2-year follow-up, without seizure recurrence. Approximately 5% of patients with epilepsy have photosensitive epilepsy, of whom a considerable proportion will experience seizures only during exposition to flashing lights. Laser photocoagulation was already successfully employed in an animal model of photosensitive epilepsy. Personal or family history of photosensitivity warrants a neurological consultation before retinal treatment with laser therapy.

RESUMO Fotocoagulação a laser é método seguro para tratamento de retinopatias. Apresentamos o caso de uma mulher de 21 anos com alta miopia e degeneração lattice bilateral que sofreu descolamento de retina no olho direito e foi submetida a tratamento cirúrgico e ulterior laserterapia. Durante a fotocoagulação no olho esquerdo, ela teve uma convulsão tônico-clônica generalizada, a primeira em sua vida. Havia história familiar de epilepsia. O exame neurológico e a ressonância magnética de en céfalo foram normais, mas o electroencefalograma revelou descargas epileptogênicas, mais frequentes durante a fotoesti mulação. Ela evitou luzes piscantes durante os 2 anos subsequentes, sem recorrência de convulsões. Cerca de 5% dos pacientes com epilepsia têm fotossensibilidade. Proporção considerável deles terá convulsões somente durante exposição à luz piscante. Fotocoagulação a laser já foi empregada como modelo animal de sucesso para epilepsia fotossensível. Presença de fotossensibilidade na história pessoal ou familiar deve merecer avaliação neurológica antes do tratamento retiniano.

Aging and Psychological Well-Being: The Possible Role of Inhibition Skills.

(1) Background: Psychological well-being (PWB) is a multidimensional construct which is a key protective factor against chronic diseases in older adults. Numerous psychological and cognitive factors can influence older people's PWB. However, while most studies have explored the effect of general cognition, only a few investigated the role of specific cognitive functions such as the efficiency of executive functions. Thus, the present study aimed to directly explore the relationships between PWB, age, and the core executive functions (namely working memory, flexibility, and inhibition). (2) Methods: A sample of 51 healthy older adults (age range: 60-88) were enrolled and tested both for PWB (by Ryff's psychological well-being scale) and the core executive functions (by the Digit span backward, the Trail Making Test, and the Stroop test). (3) Results: Age and inhibitory skills are negatively correlated to the personal growth subscale of the PWB scale. Moreover, a hierarchical regression analysis showed that inhibition, but not working memory and flexibility, predicted the sense of continued growth and development (personal growth) of older adults, even after controlling for age and educational levels. Limitations and implications for future research and prevention interventions are discussed.

Challenge your Brain. Blogging during the COVID Lockdown as a Way to Enhance Well-Being and Cognitive Reserve in an Older Population.

BACKGROUND: The lockdown linked with COVID-19 restrictions has been reported to have severe consequences at an emotional and cognitive level, this was especially true for vulnerable populations, such as the older adults. This study aims at exploring the effect of a blog-based intervention implemented during COVID lockdown to increase the perceived well-being and cognitive reserve (CR) of a sample of American older adults. METHODS: Forty-one participants (63% female), age range from 64 to 83, participated in a blog-based 5-week intervention. Their level of well-being as well as cognitive reserve were assessed before and after the intervention with specific scales. Participants were matched by age, gender and education level to a quasi-equivalent control group living in the same area who was tested on the same variables. RESULTS: Results showed a significant increase in both perceived well-being and CR in the intervention group. A significant difference was also found when comparing the intervention group to the matched controls.

The Effects of a Dance and Music-Based Intervention on Parkinson's Patients' Well-Being: An Interview Study.

Previous research has shown the positive effects of music and dance-based interventions on the physical and psychosocial symptoms of Parkinson's disease (PD). The aims of this study were: (1) to investigate how PD patients subjectively perceive the emotional, cognitive, and social benefits of a music- and dance-based intervention; (2) to apply an innovative methodology for an interview analysis combining findings from a linguistic text with an analytic approach and conducted with the software LIWC and from the content analysis performed by human coders. Extensive, open-ended interviews were conducted with 13 patients with PD who had participated in a dance and music program. The interviews were analyzed using both human coders and the computer-based approach. The results show that emotional and social aspects are considered the most frequent perceived benefits of the dance program. The data confirm the positive impact of dance- and music-based programs on promoting participants' emotional and social well-being. A combined approach to text analysis appears to be a promising way to achieve more in-depth insights into patients' subjective perceptions.

Chromogranin A plasma levels predict mortality in COVID-19.

BACKGROUND: Chromogranin A (CgA) and its fragment vasostatin I (VS-I) are secreted in the blood by endocrine/neuroendocrine cells and regulate stress responses. Their involvement in Coronavirus 2019 disease (COVID-19) has not been investigated. METHODS: CgA and VS-I plasma concentrations were measured at hospital admission from March to May 2020 in 190 patients. 40 age- and sex-matched healthy volunteers served as controls. CgA and VS-I levels relationship with demographics, comorbidities and disease severity was assessed through Mann Whitney U test or Spearman correlation test. Cox regression analysis and Kaplan Meier survival curves were performed to investigate the impact of the CgA and VS-I levels on in-hospital mortality. RESULTS: Median CgA and VS-I levels were higher in patients than in healthy controls (CgA: 0.558 nM [interquartile range, IQR 0.358-1.046] vs 0.368 nM [IQR 0.288-0.490] respectively, p = 0.0017; VS-I: 0.357 nM [IQR 0.196-0.465] vs 0.144 nM [0.144-0.156] respectively, p<0.0001). Concentration of CgA, but not of VS-I, significantly increased in patients who died (n = 47) than in survivors (n = 143) (median 0.948 nM [IQR 0.514-1.754] vs 0.507 nM [IQR 0.343-0.785], p = 0.00026). Levels of CgA were independent predictors of in-hospital mortality (hazard ratio 1.28 [95% confidence interval 1.077-1.522], p = 0.005) when adjusted for age, number of comorbidities, respiratory insufficiency degree, C-reactive protein levels and time from symptom onset to sampling. Kaplan Meier curves revealed a significantly increased mortality rate in patients with CgA levels above 0.558 nM (median value, log rank test, p = 0.001). CONCLUSION: Plasma CgA levels increase in COVID-19 patients and represent an early independent predictor of mortality.

Vasostatin-1 as a potential novel circulating biomarker in patients with chronic systolic heart failure: A pilot study.

BACKGROUND AND AIMS: Previous studies have shown that circulating chromogranin A (CgA) increases in patients with chronic systolic heart failure (HF). Aim of the present study is to evaluate the potential role of circulating vasostatin-1 (VS-1), a cardioregulatory fragment of CgA, as prognostic marker in patients with chronic HF. MATERIALS AND METHODS: The plasma levels of CgA and VS-1 were determined in 80 patients with chronic systolic HF. Patients were followed-up to evaluate the occurrence of cardiovascular (CV) events. RESULTS: CgA and VS-1 plasma levels were significantly higher in patients with CV events at follow-up. VS-1, but not CgA, was associated to NT-proBNP. No significant association of CgA and VS-1 with left ventricular ejection fraction (LVEF) was observed. CgA, NT-proBNP and age, but not VS-1, were independent predictors of CV events. CONCLUSION: In patients with chronic systolic HF those who experienced CV events had higher levels of VS-1 and CgA. Given its established effect on cardiac cells, the association of VS-1 levels with NT-proBNP levels but not with LVEF, suggests that this fragment might provide complementary information to NT-proBNP and CgA in HF patients.

Cognitive reserve: a multidimensional protective factor in Parkinson's disease related cognitive impairment.

We explored the association between cognitive reserve (CR) and Parkinson' s disease (PD) related cognitive deterioration.Forty PD patients and 12 matched healthy controls (HC) were enrolled. The PD group was balanced for the presence/absence of cognitive impairment. All participants underwent MOCA. CR was measured by the Brief Intelligence Test, and a new comprehensive tool, named Cognitive Reserve Test (CoRe-T), including sections on leisure activities and creativity.Participants with higher CR obtained a better MOCA score irrespective of the group they belonged to. At the same time, irrespective of the CR level, the performance of the HC group was always better in comparison to the PD group. Within the PD group, a higher frequency of leisure activities was associated to be cognitively unimpaired, independently by the severity of motor symptoms and age.CR could help to cope with PD-related cognitive decline. Its multidimensional nature could have important applications in prevention and rehabilitation interventions.
