Integrated Approach of Life Cycle Assessment and Experimental Design in the Study of a Model Organic Reaction: New Perspectives in Renewable Vanillin-Derived Chemicals.

This work is focused on performing a quantitative assessment of the environmental impacts associated with an organic synthesis reaction, optimized using an experimental design approach. A nucleophilic substitution reaction was selected, employing vanillin as the substrate, a phenolic compound widely used in the food industry and of pharmaceutical interest, considering its antioxidant and antitumoral potential. To carry out the reaction, three different solvents have been chosen, namely acetonitrile (ACN), acetone (Ace), and dimethylformamide (DMF). The syntheses were planned with the aid of a multivariate experimental design to estimate the best reaction conditions, which simultaneously allow a high product yield and a reduced environmental impact as computed by Life Cycle Assessment (LCA) methodology. The experimental results highlighted that the reactions carried out in DMF resulted in higher yields with respect to ACN and Ace; these reactions were also the ones with lower environmental impacts. The multilinear regression models allowed us to identify the optimal experimental conditions able to guarantee the highest reaction yields and lowest environmental impacts for the studied reaction. The identified optimal experimental conditions were also validated by experimentally conducting the reaction in those conditions, which indeed led to the highest yield (i.e., 93%) and the lowest environmental impacts among the performed experiments. This work proposes, for the first time, an integrated approach of DoE and LCA applied to an organic reaction with the aim of considering both conventional metrics, such as reaction yield, and unconventional ones, such as environmental impacts, during its lab-scale optimization.

Adapted Physical Activity Can Increase Life Appreciation in Patients with Parkinson's Disease.

Objectives:This study aimed to measure the effect of a treatment of adapted physical activity (APA) on motor symptoms and on positive psychological resources in a group of patients with PD. Methods: 37 patients with PD (Mage= 71.5; 70.3% male) completed measures of disability level, motor performance, distress, well-being, and quality of life before and after participating in a program of APA (duration: 7 months). Analysis of variance - repeated measures was performed to evaluate the effect of APA on disability, distress, and well-being. Results: After intervention, patients reported significant improvements in their motor autonomy, disability level, psychological distress, and in life appreciation. Discussion: A brief physical activity program was beneficial not only to patients' motor functioning, but also to their mental health, by reducing distress and promoting life appreciation.

The well-being and burden of caregiving for patients with Parkinson's disease.

OBJECTIVES: Well-being and positive psychological functioning may protect caregivers from experiencing burden. Despite this, research has scarcely explored these variables among caregivers of patients with Parkinson's disease (PD). This research endeavoured (1) to measure differences in distress and well-being between caregivers of PD patients and caregivers assisting individuals suffering from non-neurodegenerative age-related health problems (controls); and (2) to evaluate the predictors of well-being, distress and caregiver burden in the total sample of caregivers. METHODS: The study has a cross-sectional design. 100 caregivers were recruited from centres for ageing individuals. 50 caregivers assisted patients with PD, while the other 50 were considered as controls. Participants completed self-report questionnaires concerning psychological well-being, life satisfaction, post-traumatic growth, distress and symptomatology. Multiple regression analysis was performed on the dataset of the total sample (N = 100), exploring the possible predictors and correlates of caregiver burden. RESULTS: Caregivers who assisted patients with PD significantly experienced more depression, more distress and less well-being when compared to controls. The main significant correlates of caregiver burden were older age, less psychological well-being and more depression. CONCLUSIONS: Parkinson's disease caregivers reported more impairment in psychological well-being and higher rates of distress. In the total sample of caregivers (of patients with PD and of healthy individuals), depression and specific areas of well-being (environmental mastery, personal growth) correlated to the burden of caregiving. Psychosocial interventions focused on these dimensions may help caregivers to better cope with the possible burden of the assistance.

Exploring Post-traumatic Growth in Parkinson's Disease: A Mixed Method Study.

Post-traumatic growth (PTG) may favor the psychological adaptation to chronic illnesses. However, few studies investigated PTG in Parkinson's Disease (PD). This study aims to investigate PTG in patients with PD, by exploring disease-specific features and assessing its impact on distress, well-being, and quality of life. A mixed methodology with a convergent parallel design was used. 54 patients were classified according to their level of PTG (low PTG, medium PTG, and high PTG). PD patients with high PTG showed a more positive psychological adaptation and less distress when compared to patients with less PTG. Forty-nine patients were interviewed and their transcripts were analyzed using Thematic Analysis. The emerged themes confirmed the traditional dimensions of PTG model, but a specific theme connected to a new body awareness was identified. Patients with high PTG were more likely to report positive statements following PD diagnosis, particularly concerning spirituality and maintaining a good physical functioning. PTG presents peculiar characteristics in PD and it may favor a better psychological adjustment following the diagnosis.

Optimal Well-being, Depression, and Caregiving: An Explorative Investigation.

OBJECTIVES: Recent studies documented the protective role of hedonic and psychological well-being for mental and physical health of aging individuals. However, the combination of these two dimensions of well-being (conceptualized as optimal well-being) has been rarely evaluated in association with providing caregiving. This exploratory investigation aimed to: (1) cluster a group of community dwellers according to levels of hedonic and psychological well-being (low well-being-LWB; moderate well-being-MWB; high well-being HWB); and (2) to identify their psychosocial correlates of their optimal well-being, including providing daily caregiving. METHODS: 217 community dwellers (60-90 years) completed questionnaires concerning psychological well-being, life satisfaction, and caregivers' distress. They were classified into three groups (LWB, MWB, HWB), following a k mean cluster analysis. Chi-square and GLM were used to compare the three clusters. Regression analyses were performed to evaluate the correlates of hedonic and psychological well-being. RESULTS: Fifty-two individuals belonged to the HWB cluster, 68 to the LWB cluster and 97 to the MWB cluster. Individuals in the LWB cluster showed higher levels of anxiety and depression, and 61 of them reported to provide caregiving. Members of the HWB cluster were the oldest. Psychological and hedonic well-being negatively correlated with depression and caregiving. CONCLUSIONS: These results indicate that only a small proportion of community dwellers reported optimal well-being. CLINICAL IMPLICATIONS: Addressing depression and alleviating caregiver distress may constitute ingredients for promoting optimal well-being among older community dwellers.

Well-being and distress of patients with Parkinson's disease: a comparative investigation.

ABSTRACTBackground:Psychological resources, such as psychological well-being (PWB) and life satisfaction (LS) can aid individuals suffering from chronic illnesses to cope with their illness. The aim of this study was to investigate PWB, LS, quality of life (QoL), and distress in patients with Parkinson's disease (PD) and to compare them with healthy controls. METHODS: One hundred and thirteen individuals were recruited. Fifty of the participants suffered from PD, while 53 individuals reported other non-neurological diseases. PD patients were assessed through medical routine examinations. All participants had to be devoid of severe cognitive impairment. They were administered self-report questionnaires to measure PWB, LS, QoL, and distress. A cross-sectional comparative design was applied. RESULTS: PD patients reported higher general PWB than controls with the exception of the autonomy subscale where the PD patients scored lower. However, they also reported higher distress (anxiety, depression, somatic symptoms, and hostility-irritability), lower LS, and poorer QoL compared to controls. In regressive models, general PWB and LS were significantly correlated to the presence of PD, to its functional impairments, and not to other socio-demographic variables. CONCLUSIONS: Findings confirmed previous literature on other neurological conditions, showing that PD may be associated with greater psychological distress, lower levels of LS and QoL. At the same time, PD patients may preserve their PWB, which is a protective factor for mental and physical health. The presence of these psychological resources is inversely related to functional impairments. Future studies should better investigate the pattern of PWB in PD.

Psychological and clinical correlates of posttraumatic growth in cancer: A systematic and critical review.

OBJECTIVE: The objective of this study is to describe major findings on posttraumatic growth (PTG) in cancer, by analyzing its various definitions, assessment tools, and examining its main psychological and clinical correlates. METHODS: A search in relevant databases (PsycINFO, Pubmed, ProQuest, Scopus, and Web of Science) was performed using descriptors related to the positive reactions in cancer. Articles were screened by title, abstract, and full text. RESULTS: Seventy-two met the inclusion criteria. Most articles (46%) focused on breast cancer, used the PTG inventory (76%), and had a cross-sectional design (68%). The PTG resulted inversely associated with depressive and anxious symptoms and directly related to hope, optimism, spirituality, and meaning. Illness-related variables have been poorly investigated compared to psychological ones. Articles found no relationship between cancer site, cancer surgery, cancer recurrence, and PTG. Some correlations emerged with the elapsed time since diagnosis, type of oncological treatment received, and cancer stage. Only few studies differentiated illness-related-life-threatening stressors from other forms of trauma, and the potentially different mechanisms connected with PTG outcome in cancer patients. CONCLUSIONS: The evaluation of PTG in cancer patients is worthy, because it may promote a better adaption to the illness. However, many investigations do not explicitly refer to the medical nature of the trauma, and they may have not completely captured the full spectrum of positive reactions in cancer patients. Future research should better investigate issues such as health attitudes; the risks of future recurrences; and the type, quality, and efficacy of medical treatments received and their influence on PTG in cancer patients.

Lighten UP! A community-based group intervention to promote psychological well-being in older adults.

OBJECTIVES: Aging is often characterized by declines in physical and mental health and increased risk for depression and social isolation. A protective factor that has been found to effectively moderate these phenomena is psychological well-being. The aim of his study was to pilot test a novel group intervention (Lighten UP! program) for the promotion of psychological well-being in older adults living in the community. METHODS: Lighten UP! is an eight-week program consisting of 90-minute group session designed to teach participants to identify and savor positive experiences across multiple domains of eudaimonic well-being. It was delivered to a sample of 103 men and women aged 60 or over, that were assessed pre- and post-intervention with Ryff's Psychological Well-being Scale (PWB), Life Satisfaction scale, Geriatric Depression Scale, Symptom Questionnaire, and items measuring sleep complaints and social well-being. RESULTS: At the end of the eight weeks, participants reported significantly increased PWB, life satisfaction, and social well-being along with lower levels of depression and fewer physical symptoms and sleep complaints. These gains were particularly robust for individuals with lower pre-program levels of PWB. CONCLUSIONS: This pilot investigation suggests the feasibility of a short group program for enhancing well-being in older adults. Future controlled investigations with long-term follow-up assessment are needed to confirm the effectiveness and sustained benefits of the Lighten UP!

Beyond Ryff's scale: Comprehensive measures of eudaimonic well-being in clinical populations. A systematic review.

Eudaimonic well-being that protects mental and physical health has received increasing attention. This investigation aimed to review which comprehensive instruments for measuring eudaimonic well-being were applied with clinical populations (reporting mental or physical illnesses), beyond Ryff's Psychological Well-Being Scale. Articles citing at least 1 of the measures of eudaimonic well-being identified by previous theoretical work were extracted from medical and psychological electronic databases and screened. Only investigations involving clinical populations were included and reviewed. An initial screening identified 5,065 articles using eudaimonic well-being measures, out of which only 28 articles encompassed clinical populations and could be included. Sixteen involved patients with mental disorders and 12 populations with medical conditions. In these articles, only 4 measures of eudaimonic well-being were used (Mental Health Continuum, Flourishing Scale, General Causality Orientations Scale, and Orientations to Happiness Subscales), out of the 12 currently available in literature. The Mental Health Continuum was the most used instrument, particularly in adults with depression, whose levels of eudaimonic well-being are impaired, but may be improved by specific interventions. Autonomy appeared to influence patients' motivation to treatment, both in mental and physical disorders. The need for a larger consensus regarding specific measures of eudaimonic well-being for clinical populations emerged. The importance of including assessment of positive functioning as an indicator of recovery in clinical domains is discussed.

Psychological well-being and depression from pregnancy to postpartum among primiparous and multiparous women.

BACKGROUND: The bulk of research on motherhood has focused on perinatal depression, largely overlooking indicators of women's positive mental health which can likewise have pervasive consequences on family functioning. OBJECTIVE: The aim of the present study was to address this issue by exploring the impact of parity and childbirth on both women's perinatal depression and psychological well-being. METHODS: A convenience sample of 81 women was followed during pregnancy (Time 1) and postpartum (Time 2). At both times, participants completed the Edinburgh Depression Scale and the Psychological Well-being Scales, measuring perceived autonomy, environmental mastery, personal growth, positive relations, purpose in life, and self-acceptance. RESULTS: Significant negative correlations were observed between depression and psychological well-being dimensions. ANCOVA and mixed ANOVA analyses showed that depression levels did not differ between primiparous and multiparous women, or between pre- and postpartum assessments. By contrast, after childbirth, primiparous women reported higher values of environmental mastery and self-acceptance than multiparous women. In addition, levels of self-acceptance and personal growth increased from pregnancy to postpartum among primiparous women, while no differences were detected over time in the scores of all the psychological well-being dimensions among multiparous women. CONCLUSIONS: This study highlighted some dimensions of positive psychological functioning that specifically contribute to women's well-being in the transition to motherhood, and their different relevance for primiparous and multiparous mothers. Future trials are needed to integrate this information in tailored intervention for the promotion of mothers' complete mental health.

The Promotion of Well-Being in Aging Individuals Living in Nursing Homes: A Controlled Pilot Intervention with Narrative Strategies.

OBJECTIVES: The study aimed: (1) to compare levels of well-being and distress in older adults living in nursing homes with those living in community; and (2) to test the feasibility of a positive narrative intervention for improving well-being versus a control art-and-craft intervention in a nursing home setting. METHODS: Sixty older adults participated in the study (M = 77.37; SD = 5.00), Male = 20 (33.3%). In Study 1, 30 adults living in nursing homes were compared with 30 community-dwellers using the following measures: Satisfaction with Life Scale, Psychological Well-being Scale, Social Well-being Scale, Geriatric Depression Scale, and sleep quality. In Study 2, the same 30 adults living in nursing homes were allocated to a positive narrative intervention group (N = 20) or to a control group (N = 10) and assessed at post-intervention. RESULTS: In Study 1, older adults in nursing homes presented more depression and impairments in well-being, compared to community-dwellers. In Study 2, at post-treatment, individuals assigned to the narrative intervention reported significantly increased well-being and sleep quality. CONCLUSIONS: Although preliminary, results showed that older adults living in nursing homes are more vulnerable than community-dwellers. These patients experienced improvement when given a short group positive narrative intervention applicable in nursing homes. CLINICAL IMPLICATIONS: A brief group intervention based on fairy tales yielded improvements in well-being and sleep quality in nursing home residents, who enjoyed and appreciated its content. These promising results need to be confirmed by future randomized controlled trials.

Positive mental health, depression and burnout in healthcare workers during the second wave of COVID-19 pandemic.

WHAT IS KNOWN ON THE SUBJECT?: In the past 2 years, the COVID-19 pandemic had a robust negative impact on the mental health of healthcare providers, with increasing rates of depression, anxiety, acute stress and burnout. Healthcare workers experiencing poor mental health are reluctant to seek help and treatment because they are afraid of being stigmatized and excluded by their colleagues and employers. During the pandemic positive emotions, resilience and psychological well-being buffered distress and burnout in healthcare workers. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: This paper describes positive mental health, depression, anxiety and burnout in healthcare workers during the second wave of the pandemic. Forty-eight per cent of healthcare workers were flourishing (high levels of positive emotions and well-being), 10% languishing (absence of well-being and positivity). Flourishing individuals reported lower levels of depression, anxiety and burnout. These findings documented a relevant number of resilient healthcare workers, who restored/maintained their well-being also under stressful conditions. Vulnerable healthcare workers were less than 20%, and they reported severe anxiety, depression and burnout. No differences emerged between languishing and moderate mental health groups in their levels of anxiety, depression and burnout. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: The condition of flourishing is the only one that provides protection from depression and anxiety and burnout, while moderate mental health does not differ substantially from the languishing state. The study confirms the importance of maintaining and/or promoting the well-being of healthcare workers. Interventions for promoting positive mental health of vulnerable workers are needed. Mental health nurses can have the skills and expertise for evaluating early symptoms of psychological distress and for implementing interventions for promoting and restoring well-being. These interventions may include informational campaign (i.e. preparing and distributing pamphlets and guidelines) and emotional support programmes (psychoeducation and training, mental health support team, peer support and counselling) that can be delivered also via digital platforms. ABSTRACT: INTRODUCTION: Few studies focused on healthcare workers' positive mental health (i.e. high levels of psychological well-being) and its association with anxiety, depression and burnout in the second wave of the pandemic. AIMS: To evaluate the protective role of well-being in buffering burnout and psychological distress. METHODS: We evaluated 173 Italian healthcare workers with indicators of psychological distress (Depression Anxiety Stress Scales [DASS]-21), burnout (Copenhagen Burnout Inventory [CBI]) and positive mental health (Mental Health Continuum) and we cross-classified them according to their levels of mental health (flourishing, languishing and moderate mental health) and their levels of anxiety, depression and burnout. RESULTS: Forty-eight per cent of health workers were classified as flourishing, 10% as languishing and 42% as moderate mental health. Flourishing individuals presented lower scores on DASS and CBI scales, whereas no differences emerged between languishing and moderate mental health groups. More than 80% of health workers with clinically significant symptoms of anxiety, depression and risk of burnout were classified as not flourishing. DISCUSSION: This investigation documented the presence of flourishing mental health in almost half of the sample of Italian healthcare workers. However, those with moderate or languishing mental health manifested higher levels of anxiety, depression and higher risks of burnout. IMPLICATION FOR PRACTICE: The study confirms the importance of maintaining and/or promoting the well-being of this population, with a crucial role of mental health nurses who can easily approach other healthcare workers and provide them informational (training, guidelines) and emotional support programmes (psychoeducation, mental health support team, peer support and counselling) when facing adverse working conditions.

A pharmacoeconomic analysis from Italian guidelines for the management of prolactinomas.

Background: Prolactinoma, the most common pituitary adenoma, is usually treated with dopamine agonist (DA) therapy like cabergoline. Surgery is second-line therapy, and radiotherapy is used if surgical treatment fails or in relapsing macroprolactinoma. Objective: This study aimed to provide economic evidence for the management of prolactinoma in Italy, using a cost-of-illness and cost-utility analysis that considered various treatment options, including cabergoline, bromocriptine, temozolomide, radiation therapy, and surgical strategies. Methods: The researchers conducted a systematic literature review for each research question on scientific databases and surveyed a panel of experts for each therapeutic procedure's specific drivers that contributed to its total cost. Results: The average cost of the first year of treatment was €2,558.91 and €3,287.40 for subjects with microprolactinoma and macroprolactinoma, respectively. Follow-up costs from the second to the fifth year after initial treatment were €798.13 and €1,084.59 per year in both groups. Cabergoline had an adequate cost-utility profile, with an incremental cost-effectiveness ratio (ICER) of €3,201.15 compared to bromocriptine, based on a willingness-to-pay of €40,000 per quality-adjusted life year (QALY) in the reference economy. Endoscopic surgery was more cost-effective than cabergoline, with an ICER of €44,846.64. Considering a willingness-to-pay of €40,000/QALY, the baseline findings show cabergoline to have high cost utility and endoscopic surgery just a tad above that. Conclusions: Due to the favorable cost-utility profile and safety of surgical treatment, pituitary surgery should be considered more frequently as the initial therapeutic approach. This management choice could lead to better outcomes and an appropriate allocation of healthcare resources.

Post-traumatic growth in breast cancer survivors: new insights into its relationships with well-being and distress.

Research investigating possible relations between Post-traumatic growth (PTG) and clinical indexes--such as psychosocial distress, physical and psychological well-being--is lacking in medical settings. The aim of this study was to look into such relationships in breast cancer survivors (Bcs) and in healthy control subjects who experienced other stressful events. Sixty Bcs and 60 healthy women reporting other stressful events were compared according to the following scales: Post-traumatic Growth Inventory, Psychological Well-being Scales (PWB), Symptom Questionnaire and Psychosocial Index. Bcs reported significantly higher levels of PTG and distress, and lower levels of PWB compared to healthy women. Bcs with high levels of PTG showed increased levels of physical well-being and decreased distress. Healthy women under stressful circumstances reporting high levels of PTG showed increased levels of PWB. PTG levels were higher in Bcs and associated with decreased psychological distress and somatisation. These results carry important implications for clinical assessment, as well as for planning interventions to improve well-being and resilience in oncology.

Improving Purpose in Life in School Settings.

Background and aim: The dimension of purpose in life (PiL) is one of the core features of eudaimonia and plays a crucial role in developmental settings. However, few studies have examined purpose in life in younger generations and verified if it is amenable to improvements following a wellbeing-promoting intervention. The aim of the present investigation is to explore correlates and predictors of purpose in life in school children and to test if it can be ameliorated after school-based wellbeing interventions. Methods: A total of 614 students were recruited in various schools in Northern Italy. Of these, 456 belonged to junior high and high schools and were randomly assigned to receive a protocol of School Well-Being Therapy (WBT) or a psychoeducational intervention (controls). A total of 158 students were enrolled in elementary schools and received a positive narrative intervention based on fairytales or were randomly assigned to controlled conditions. All students were assessed pre- and post- intervention with Ryff scales of eudaimonic wellbeing (short version) and with other self-report measures of anxiety, depression and somatization. Additionally, the Strengths and Difficulties Questionnaire (SDQ) was administered to their schoolteachers as observed-rated evaluation. Results: In both elementary and high schools, purpose in life after the intervention was predicted by initial depressive symptoms and by group assignment (positive interventions vs. controls). In older students, PiL was predicted by female gender and anxiety levels, while no specific strengths identified by teachers were associated with PiL. Conclusions: PiL plays an important and strategic role in developmental settings, where students can develop skills and capacities to set meaningful goals in life. Depressive symptoms and anxiety can be obstacles to developing PiL in students, while positive school-based interventions can promote this core dimension of eudaimonia.

The Use of Virtual Reality Interventions to Promote Positive Mental Health: Systematic Literature Review.

BACKGROUND: A large body of research has documented the efficacy of psychological interventions integrated with virtual reality (VR) therapies in treating psychiatric disorders. However, the concept of positive mental health calls for a 2-fold approach in which both symptoms and positive functioning should be addressed by modern interventions. OBJECTIVE: This review aimed to summarize studies that applied VR therapies by embracing the positive mental health perspective. METHODS: A literature search was conducted by entering the following keywords-"virtual reality" AND "intervention" OR "treatment" OR "therapy" AND "mental health" NOT "systematic review or meta-analysis"-and limiting it to "journal article" and the English language. To be included in this review, articles had to present at least one quantitative measure of positive functioning and one quantitative measure of symptoms or distress and had to investigate adult populations, including populations with psychiatric disorders. RESULTS: A total of 20 articles were included. They described various VR protocols that were applied for the treatment of anxiety disorders (5/20, 25%), depression (2/20, 10%), posttraumatic stress disorder (3/20, 15%), psychosis (3/20, 15%), and stress (7/20, 35%). Most of the studies (13/20, 65%) showed the beneficial effects of VR therapies in improving stress and negative symptoms. However, 35% (7/20) of the studies showed no or a small effect on the various dimensions of positivity, particularly in clinical samples. CONCLUSIONS: VR interventions might be cost-effective and largely scalable, but further research is needed to develop existing VR software and treatments according to the modern positive mental health approach.

Protocol for a Randomized Controlled Trial Testing the Efficacy of a Transdiagnostic Virtual Reality-Based Intervention for the Reduction of Unhealthy Lifestyles and Behaviors in the General Population.

Virtual reality (VR) is a valuable tool for the treatment and prevention of psychiatric disorders and dysfunctional behaviors. Although VR software is mainly developed following a disorder-specific approach, this randomized controlled trial (RCT) will test the efficacy of a new transdiagnostic VR application (H.O.M.E. VR-based psychological intervention) in improving dysfunctional behaviors, three transdiagnostic factors concurrently (emotion regulation, experiential avoidance, and psychological flexibility), and stress. Three groups screened as at-risk for nicotine dependence, alcohol abuse, and eating disorders will be assigned to the H.O.M.E. VR intervention and compared to a waiting-list (WL) condition. Participants will be assessed before and after the H.O.M.E. intervention/WL and at the 3- and 6-month follow-ups in the levels of the displayed dysfunctional behavior, the three transdiagnostic factors, and stress. Changes in dysfunctional behaviors, transdiagnostic factors, and stress in each population VR group and differences in such improvements between each population of the VR and WL groups will be evaluated using mixed-model repeated measure analyses of variance. It is expected that, after the H.O.M.E. intervention and at follow-ups, participants will display improvements in physical and psychological health compared to controls. The H.O.M.E. protocol is expected to result in a cost-effective option to tackle cognitive-behavioral factors shared among several psychopathologies and dysfunctional behaviors.

Life Cycle Impact Assessment of Solution Combustion Synthesis of Titanium Dioxide Nanoparticles and Its Comparison with More Conventional Strategies.

This paper represents the first attempt to quantitatively and reliably assess the environmental sustainability of solution combustion synthesis (SCS) with respect to other soft chemistry strategies, which are more conventionally employed in the preparation of engineered oxide nanomaterials, namely hydrolytic and non-hydrolytic sol-gel syntheses (i. e., HSGS and NHSGS). Indeed, although SCS is well known to rely on significant reduction in the energy as well as time required for the obtainment of the desired nanocrystals, its quantitative environmental assessment and a detailed comparison with other existing synthetic pathways represents an absolute novelty of high scientific desirability in order to pursue a more sustainable development in the inorganic chemistry as well as materials science research fields. TiO2 nanoparticles were selected as the material of choice, for the production of which three slightly modified literature procedures were experimentally reproduced and environmentally evaluated by the application of the comprehensive life cycle assessment (LCA) methodology. Particularly, SCS was compared from an environmental perspective with sol-gel approaches performed both in water and in benzyl alcohol. The results of the present study were also framed among those recently obtained in a systematic study assessing seven further chemical, physical, and biological routes for the synthesis of TiO2 nanoparticles, comprising also flame spray pyrolysis (typically used in industrial productions), highlighting and quantifying the excellent environmental performances of SCS.

Innovative Bioplasticizers from Residual Cynara cardunculus L. Biomass-Derived Levulinic Acid and Their Environmental Impact Assessment by LCA Methodology.

This work is focused on the application of Life Cycle Assessment (LCA) methodology for the quantification of the potential environmental impacts associated with the obtainment of levulinic acid from residual Cynara cardunculus L. biomass and its subsequent valorization in innovative bioplasticizers for tuning the properties as well as the processability of biopolymers. This potentially allows the production of fully biobased and biodegradable bioplastic formulations, thus addressing the issues related to the fossil origin and nonbiodegradability of conventional additives, such as phthalates. Steam explosion pretreatment was applied to the epigean residue of C. cardunculus L. followed by a microwave-assisted acid-catalyzed hydrolysis. After purification, the as-obtained levulinic acid was used to synthesize different ketal-diester derivatives through a three-step selective synthesis. The levulinic acid-base additives demonstrated remarkable plasticizing efficiency when added to biobased plastics. The LCA results were used in conjunction with those from the experimental activities to find the optimal compromise between environmental impacts and mechanical and thermal properties, induced by the bioadditives in poly(3-hydroxybutyrate), PHB biopolymer.

Healthy Eating as Potential Mediator of Inverse Association between Purpose in Life and Waist Circumference: Emerging Evidence from US and Chilean Cohorts.

High sense of purpose in life, a fundamental domain of eudaimonic well-being, has been consistently associated with lower risk for various obesity-related chronic diseases. Although this psychological feature correlates with some health behaviors as potential mediators, its association with healthy eating remains less explored. In addition, studies of these psycho-behavioral and health relationships in the South American population are lacking. This research sought to assess: (1) the cross-sectional association between self-reported purpose in life and overall healthy eating patterns, and (2) healthy food intake as a potential mediator of the inverse relationship between purpose in life and waist circumference. Data collected of 2060 US adults from the MIDUS study (5 ± 12 years, 55% women, mostly white people, and 42.5% obese) and 223 Chilean adults from the CHILEMED study (46.6 ± 9 years, 58.3% women, and 71.3% obese) were used. Anthropometric and sociodemographic variables were collected. Sense of purpose was assessed using the purpose in life subscale of the Ryff's psychological well-being questionnaire. Diet quality was evaluated using healthy eating or low-fat diet indexes, according to extant food intake data in each cohort. The relationship between these variables was estimated by bivariate and multivariate linear regressions with appropriate adjustments. To establish whether a better diet quality could mediate a link of purpose in life and improved nutritional status (assessed by waist circumference), the association between these three variables was tested by bootstrapping-based mediation analysis. Our results show significant associations of sense of purpose with healthy eating and low-fat dietary patterns in both US and Chilean cohorts, respectively, even after adjusting for sociodemographic variables. According to the mediation analysis, the relationship between sense of purpose and waist circumference, as an indicator of abdominal obesity, appears to be partially mediated by healthier food intake in both samples. In conclusion, our findings suggest a plausible mechanism underlying the favorable impact of this well-being dimension on physical health. Given its protective effects, interventions aimed at increasing purpose in life may facilitate adherence to better dietary patterns, which, in turn, will reduce the risk for obesity-related chronic diseases.
