RESUMEN

Introduction: Obesity and eating disorders are considered to be part of a broad spectrum of disorders associated with weight issues and maladaptive eating styles. Several studies show that psychopathological and personality characteristics contribute to the development and maintenance of obesity and dysfunctional eating behaviors, showing a bidirectional relationship. The purpose of this study was to understand the role of psychopathological factors and personality dimensions on dysfunctional eating behaviors in a sample of individuals with obesity. Methods: The study was conducted with 96 individuals with obesity (31 males and 65 females) who underwent psychological assessment. The instruments administered included the Cognitive Behavioral Assessment 2.0 - Primary Scales, the Minnesota Multiphasic Personality Inventory-2, and the Eating Disorder Inventory. Relationships between dysfunctional eating behaviors and personality and psychopathological factors were explored through mediation analysis. Results and discussion: Our results showed that difficulties related to impulse control and behavior, along with negative and dysphoric emotions, may be associated with difficulties in eating behavior. Mediation analysis showed that the combination of depressive and obsessive-compulsive symptomatology may exacerbate or contribute to the occurrence of eating disorders. These psychopathological aspects should be taken into account during the assessment of patients who decide to undergo bariatric surgery and should be targets of specific psychological interventions.

RESUMEN

PURPOSE: Literature supports the use of technological tools such as augmented reality, 3 D avatars and mobile devices to improve individuals with autism spectrum disorder skills. Possibilities of including these technological tools in intervention and the critical issues related to intervention design are essential research questions. The aim of the current work is to present an interdisciplinary research study on the design of an autism intervention considering these technologies. MATERIALS AND METHODS: This study used qualitative evidence and thematic analysis to identify the main design guidelines. A semi-structured interview was administered to a total of twenty participants representing four stakeholder categories: ASD, clinicians, therapists and caregivers. Interviews focussed on three dimensions related to user, technology and environment since they represent a complex system within which the individual using technology is situated. RESULTS: Thematic analysis of the interviews identified a total of 10 themes considered central to the design of the technological intervention. CONCLUSIONS: Since the application of technology in autism intervention is a relatively new area, the guidelines related to the potential incentives and barriers of the proposed technology are helpful to inform future treatment studies.Implications for RehabilitationThis study highlights the strengths and barriers associated with the use of smartphones and augmented reality in autism spectrum disorder interventions considering the dimensions within which the user using assistive technology is located.Strengths and major concerns that emerged are key points to consider during the development of the technological intervention.Considering these points can foster the use of technology within the intervention and promote its effectiveness.

RESUMEN

Early diagnosis is crucial for Autism spectrum disorder (ASD) and is achieved through a screening of developmental indicators to recognise children who are at risk of autism. One of the most widely used instruments in clinical practice for assessing child development is the Griffiths Mental Development Scale (GMDS). We sought (a) to assess longitudinally whether children diagnosed with ASD, with a mean age of 33.50 months (SD 7.69 months), show a developmental delay of abilities measured by the GMDS over time and (b) to analyse which skills of the GMDS could be associate to the symptomatologic severity of ASD. Our results showed lower scores of General Quotient and all sub-quotients of GMDS from first (T0) to second assessment (T1), except for the Performance sub-quotient. Three sub-quotients (Personal-Social, Hearing and Language and Practical Reasoning) also associate symptom severity at the time when the diagnosis of ASD is made.

RESUMEN

On March 9, 2020, Italy has gone into "lockdown" because of COVID-19 pandemic, with a national quarantine. All non-essential working activities and schools of all levels have been temporarily closed: consequently, the entire population have been forced to dramatically change their daily habits. The pandemic raised important psychological, moral, social, and economic issues. Our research focused on the moral decision-making of people during an emergency. This paper reports two studies. The aim of Study 1 was to evaluate moral decision-making, level of perceived stress, ability of mentalizing and empathy in university students and Italian workers. 224 front-line workers (FLW), 413 second-line workers (SLW), and 663 university students (US), during Italian Phase 1 of lockdown, completed an online questionnaire. The results of Study 1 showed that participants in the FLW group are more likely to choose utilitarian solutions and judge as morally acceptable actions finalized to saving lives of more people if this requires sacrificing a low number of individuals. At the same time, decision-making was experienced as less unpleasant and less arousing with respect to the other two groups, demonstrating a greater ability to keep emotional control under pressure. In Study 2, we compared the same variables used in Study 1, selecting two professional categories from the FLW group engaged in emergency during COVID-19, namely healthcare providers (n = 82) and public safety personnel (n = 117). Our results showed that healthcare providers were more stressed and emotionally involved than public safety personnel, with higher empathic concern and arousal in moral decision-making. We suggest it is essential providing immediate psychological support and monitoring physical and emotional well-being for workers in the front-line during emergencies like the COVID-19 pandemic, in order to prevent experiences of moral distress or mental health problems.

RESUMEN

Children with autism spectrum disorder (ASD) are characterized by difficulties in social cognition (SC) domains. The aim of this study is to build an SC network to explore associations among interacting elements within this cognitive construct. We used a graph analysis to explain how individual SC domains relate to each other and how these relations may differ between ASD and typically developing (TD) groups. Seventy-six children with ASD and 81 TD children, matched for verbal mental age, were subjected to three SC measures. Our results showed that TD children exhibited an SC network characterized by a single domain (i.e., social cognition), while children with ASD demonstrated communicating node communities where social information processing measured by the Social Information Processing Interview (SIPI) represents a key point in understanding network differences between groups.

RESUMEN

BACKGROUND: An understudied area of interest in post-disaster public health is individuals' use of social networks as a potential determinant of quality of life (QOL) and mental health outcomes. A population-based cross-sectional study was carried out to examine whether continual use of online social networking (Facebook) in an adult population following a massive earthquake was correlated with prevalence of depression and post-traumatic stress disorders (PTSD) and QOL outcomes. METHODS: Participants were a sample of 890 adults aged 25-54 who had been exposed to the L'Aquila earthquake of 2009. Definition of "user" required a daily connection to the Facebook online social network for more than 1 h per day from at least 2 years. Depression and PTSD were assessed using the Screening Questionnaire for Disaster Mental Health. QOL outcomes were measured using the World Health Organisation Quality of Life BREF (WHOQOL-BREF) instrument. Logistic regression was carried out to calculate the prevalence odds ratios (POR) for social network use and other covariates. RESULTS: Two hundred and twenty one of 423 (52.2%) men, and 195 of 383 (50.9%) women, had been using Facebook as social network for at least 2 years prior to our assessment. Social network use correlated with both depression and PTSD, after adjusting for gender. A halved risk of depression was found in users vs. non-users (POR 0.50 ± 0.16). Similarly, a halved risk of PTSD in users vs. non-users (POR 0.47 ± 0.14) was found. Both men and women using online social networks had significantly higher QOL scores in the psychological and social domains of the WHOQOL-BREF. CONCLUSION: Social network use among adults 25-54 years old has a positive impact on mental health and QOL outcomes in the years following a disaster. The use of social networks may be an important tool for coping with the mental health outcomes of disruptive natural disasters, helping to maintain, if not improve, QOL in terms of social relationships and psychological distress.

RESUMEN

BACKGROUND: People's well-being after loss resulting from an earthquake is a concern in countries prone to natural disasters. Most studies on post-earthquake subjective quality of life (QOL) have focused on the effects of psychological impairment and post-traumatic stress disorder (PTSD) on the psychological dimension of QOL. However, there is a need for studies focusing on QOL in populations not affected by PTSD or psychological impairment. The aim of this study was to estimate QOL changes over an 18-month period in an adult population sample after the L'Aquila 2009 earthquake. METHODS: The study was designed as a longitudinal survey with four repeated measurements performed at six monthly intervals. The setting was the general population of an urban environment after a disruptive earthquake. Participants included 397 healthy adult subjects. Exclusion criteria were comorbidities such as physical, psychological, psychiatric or neurodegenerative diseases at the beginning of the study. The primary outcome measure was QOL, as assessed by the WHOQOL-BREF instrument. A generalised estimating equation model was run for each WHOQOL-BREF domain. RESULTS: Overall, QOL scores were observed to be significantly higher 18 months after the earthquake in all WHOQOL-BREF domains. The model detected an average increase in the physical QOL scores (from 66.6 ± 5.2 to 69.3 ± 4.7), indicating a better overall physical QOL for men. Psychological domain scores (from 64.9 ± 5.1 to 71.5 ± 6.5) were observed to be worse in men than in women. Levels at the WHOQOL domain for psychological health increased from the second assessment onwards in women, indicating higher resiliency. Men averaged higher scores than women in terms of social relationships and the environmental domain. Regarding the physical, psychological and social domains of QOL, scores in the elderly group (age > 60) were observed to be similar to each other regardless of the significant covariates used. CONCLUSIONS: WHOQOL-BREF scores of the psychological domain displayed trends conditioned by age and education: older subjects experienced less satisfaction with psychological health on average. Less-educated subjects always demonstrated the worst QOL scores. Gender, age and education impacted the variability of QOL in the environmental dimension in the elderly.

RESUMEN

INTRODUCTION: Aim of this study was to implement and validate the Italian version of the Screening Questionnaire for Disaster Mental Health (SQD), a tool for the screening of post-traumatic stress disorder (PTSD) and depression in the long-term aftermaths of a natural disaster. METHODS: A convenience sample of 116 subjects living in L'Aquila after the 2009 earthquake were administered the SQD and two gold-standard instruments for PTSD and depression. Reliability, concurrent validity and convergent validity of SQD were estimated. RESULTS: Cronbach's alpha was 0.86. Concurrent validity as measured by the Spearman correlation coefficient resulted statistically significant both for PTSD and depression SQD subscales, as well as convergent validity as measured by ROC-AUC method. CONCLUSIONS: SQD is a valid, efficient and easy-to-use screening instrument for PTSD and depression after natural disasters.

RESUMEN

OBJECTIVE: To assess and estimate the personality changes that occurred before and after the 2009 earthquake in L'Aquila and to model the ways that the earthquake affected adolescents according to gender and sport practice. The consequences of earthquakes on psychological health are long lasting for portions of the population, depending on age, gender, social conditions and individual experiences. Sports activities are considered a factor with which to test the overall earthquake impact on individual and social psychological changes in adolescents. DESIGN: Before and after design. SETTING: Population-based study conducted in L'Aquila, Italy, before and after the 2009 earthquake. PARTICIPANTS: Before the earthquake, a random sample of 179 adolescent subjects who either practised or did not practise sports (71 vs 108, respectively). After the earthquake, of the original 179 subjects, 149 were assessed a second time. PRIMARY OUTCOME MEASURE: Minnesota Multiphasic Personality Inventory-Adolescents (MMPI-A) questionnaire scores, in a supervised environment. RESULTS: An unbalanced split plot design, at a 0.05 significance level, was carried out using a linear mixed model with quake, sex and sports practice as predictive factors. Although the overall scores indicated no deviant behaviours in the adolescents tested, changes were detected in many individual content scale scores, including depression (A-dep score mean ± SEM: before quake =47.54±0.73; after quake =52.67±0.86) and social discomfort (A-sod score mean ± SEM: before quake =49.91±0.65; after quake =51.72±0.81). The MMPI-A profiles show different impacts of the earthquake on adolescents according to gender and sport practice. CONCLUSIONS: The differences detected in MMPI-A scores raise issues about social policies required to address the psychological changes in adolescents. The current study supports the idea that sport should be considered part of a coping strategy to assist adolescents in dealing with the psychological effects of the earthquakes on their personalities.

RESUMEN

Damage to health associated with emissions from coal power stations can vary greatly from one location to another depending on the size of the plant, location and the characteristics of the population. Population-based studies conducted by independent groups in different locations around the world show effects on health in populations at higher risk, but failed to definitely demonstrate direct effects on morbidity and mortality, to be exclusively attributed to the presence of active power stations. However, evidence on the role of micropollutants from power station activities suggests that a complete and thorough analysis should be made on the environmental cycle. Therefore danger should in any case be assessed as carefully as possible while assuming, at most, that all micropollutants may come into direct contact with man through the various potential pathways throughout their entire lifetime, regardless of the factors that reduce their presence.

RESUMEN

Tumor necrosis factor (TNF)-α is a pro-inflammatory cytokine associated with psoriasis pathogenesis. Anti-TNF-α therapies are effective in psoriasis. A significant weight gain has been reported in patients treated with anti-TNF-α agents. The aim of the present study was to evaluate the body composition changes in psoriatic patients receiving anti-TNF-α therapies according with disease phenotype. Forty patients affected with psoriasis were followed up for 24 weeks and divided into two groups: psoriasis vulgaris (PsO) and psoriatic arthritis (PsA). Anthropometric, blood biochemical, body composition parameters, resting metabolic rate, and disease activity indexes were measured at baseline and at week 24. After 24 weeks of anti-TNF-α administration, the disease activity indexes and concentration of inflammatory markers were significantly decreased. Seventy-five percent of PsO and 60% of PsA patients had an increase in body weight. Weight changes correlated with fat mass gain in the PsO group, and with fat and lean mass gain in the PsA group. In the present study, we demonstrated that a blockage of TNF-α bioactivity is related with fat and lean mass gain in both PsO and PsA subjects. The anti-TNF-α therapies could play a key role in the cross talk between adipose tissue and skeletal muscle, mediated by the reduction of TNF-α and interleukin-6 production.

RESUMEN

INTRODUCTION: Prurigo nodularis is a distressing condition characterized by the presence of multiple nodules associated with intense pruritus. OBJECTIVE: To assess the clinical efficacy and safety of betamethasone valerate 0.1% tape and a moisturizing itch-relief cream in prurigo nodularis. METHODS: Twelve patients were enrolled in this pilot comparison of betamethasone valerate 0.1% tape versus a moisturizing itch-relief cream containing feverfew. The study period was 4 weeks. Clinical evaluation was performed weekly. RESULTS: Eleven subjects completed the 4 weeks of therapy. The mean visual analogue scale (VAS) for pruritus at baseline was 8.75 for both sides of the body. The side treated with betamethasone valerate 0.1% tape showed a higher clinical response (VAS score at week 4: 3.9; p < 0.005) compared with the side treated with moisturizing itch-relief cream (VAS score at week 4: 5.6; p < 0.005). CONCLUSION: Both treatments were effective. However, the occlusive dressing enhanced the efficacy of the treatment, preventing scratching.

RESUMEN

Smoking is a significant independent risk factor for cardiovascular disease and is a leading cause of structural and functional alterations of the cardiovascular system. Increasing evidence supports the hypothesis that oxidative stress and endothelial dysfunction are the fundamental pathophysiological mechanisms linking cigarette smoking to cardiovascular disease. The cardiovascular system is a rich source of NADPH oxidase-derived reactive oxygen species, which under pathological conditions play a fundamental role in vascular damage. Endothelium-derived nitric oxide (NO) plays a major role in the regulation of vascular tone, structure, and function, and endothelial dysfunction could be considered the first step in the pathogenesis of atherosclerosis and cardiovascular disease. Indeed, the bioavailability of NO is modulated by reactive oxygen species that degrade NO, uncouple NO synthase, and inhibit synthesis. Reduced bioavailability of NO and consequent endothelial dysfunction are involved in the initiation, progression and complications of atherosclerosis and also are predictive of future cardiovascular events. Thus, although data from clinical trials exploring the role of antioxidants on cardiovascular risk and disease are equivocal as yet, the role of oxidative stress in cardiovascular disease is an important area of research, which is likely to continue to be fruitful. This review focuses on possible interactions between oxidative stress, endothelial dysfunction and cigarette smoking--favouring the atherosclerotic process and cardiovascular disease--also focusing on the potential role for antioxidants in the prevention of adverse cardiovascular outcomes.

RESUMEN

A large body of evidence supports that the dietary intake of polyphenols - particularly of flavonoids and the specific class of flavonoids named flavanols - might be able to exert some beneficial vascular effects and reduce the risk for cardiovascular morbidity and mortality. The review of epidemiological and mechanistic studies supports the role of flavonoids, particularly cocoa and tea flavanols, in protecting the cardiovascular system against cardiovascular disease. Nevertheless, flavonoids are an heterogeneous group of natural molecules differently represented in fruit and vegetables and definitive data on cardiovascular benefits are lacking. The weakness of the available data include few and very small studies, no crossover designed studies and a wide range of dose and type of flavonoids tested. Thus, although flavonoid-rich foods and beverages are likely to protect cardiovascular system, further research is needed to characterize the mechanism of action on flavanol-rich foods. Long-term clinical trials are also needed to definitively clarify the benefits deriving from long-term consumption of flavanol-rich foods, particularly focussing on the lowest effective levels as well as synergism or antagonistic actions between different classes of flavonoids commonly found in foods.

RESUMEN

We evaluated risk factors such as socio-demographic characteristics, smoking habits and alcohol consumption, associated with hypertension, diabetes and obesity in psoriasis patients, in order to plan health education programs that could prevent the onset or progression of co-morbidities. The study population consisted of 1376 patients with psoriasis who were consecutively recruited at 21 Italian Departments of Dermatology. Information concerning socio-demographic variables, smoking and alcohol consumption, and the presence of chronic disorders such as hypertension, type 2 diabetes and obesity was collected. The risk of co-morbidities according to the various exposure variables was calculated using logistic regression models. Psoriasis patients living in extremely urban areas showed the highest risk of diabetes (OR = 1.99, 95% CI 1.06-5.23) and obesity (OR = 2.60, 95% CI 1.10-16.12), as compared to patients living in rural areas. The OR for hypertension was higher for smokers (> 15 cigarettes per day, OR = 1.37, 95% CI 1.01-2.03) and drinkers (> 2 glasses/day of wine, OR = 2.11, 95% CI 1.31-3.40). The OR for diabetes or obesity was higher for drinkers: 1 drink/day (OR = 1.93, 95% CI 1.01-3.67) and > 1 drink/day of spirits (OR = 2.90, 95% CI 1.43-5.82), respectively. The results of our survey highlight the need to detect psoriasis patients with different susceptibilities to co-morbidities in order to plan specific health campaigns aimed at changing people's lifestyles with respect to smoking, drinking and diet.

RESUMEN

Angiotensin converting enzyme inhibitors (ACE-I) are able to reduce the formation of the potent vasoconstrictor endothelin-1 and increase nitric oxide bioavailability in human vascular endothelial cells (HUVECs). We tested the effects of two sulfhydryl-containing ACE-I, zofenoprilat, and captopril, and two nonsulfhydryl containing ACE-I, enalaprilat and lisinopril, on endothelin-1/nitric oxide balance and oxidative stress in HUVECs. All the four tested ACE-I reduced endothelin-1 secretion and increased nitric oxide metabolite production by HUVECs. However, zofenoprilat (-42% after 8 hours of incubation) was more effective (P < .05) than enalaprilat (-25%), lisinopril (-21%), and captopril (-30%) in reducing endothelin-1 secretion. Similarly, zofenoprilat (+110% after 8 hours of incubation) was more effective (P < .05) than enalaprilat (+64%), lisinopril (+63%), and captopril (+65%) in increasing nitric oxide metabolite production. The effect of ACE-I on endothelin-1 and nitric oxide metabolite production is mediated by the activation of bradykinin B(2) receptor being counteracted, at least in part, by a specific antagonist. Zofenoprilat and, to a lesser extent, captopril also reduced oxidative stress in HUVECs. In conclusion, among the four tested ACE-I, zofenoprilat was more effective in improving endothelin-1/nitric oxide balance in HUVECs likely because of its greater antioxidant properties.

RESUMEN

Thiazolidinediones (TZDs) are widely used in the type 2 diabetes mellitus (DMT2) treatment but have also been tested in cardiovascular prevention. DMT2 is associated with a marked increment in cardiovascular risk, and its prevention represents a main target in cardiometabolic protection. Both Troglitazone (Troglitazone in Prevention of Diabetes study) and Rosiglitazone (Diabetes Reduction Assessment with Ramipril and Rosiglitazone Medication study) significantly reduced new-onset diabetes. A similar topic will be investigated with pioglitazone (Actos Now for Prevention of Diabetes). In the Prospective Pioglitazone Clinical Trial in Macrovascular events the primary end point (all-cause mortality, nonfatal myocardial infarction, stroke, acute coronary syndromes, endovascular or surgical intervention in the coronary/leg arteries and amputation above ankles) was unaffected, whereas the secondary one (all-cause mortality, nonfatal myocardial infarction and stroke) was reduced by pioglitazone (-16%, p=0.027) compared to placebo in 5,238 patients with DMT2 and macrovascular disease. In contrast, a meta-analysis (Nissen and Wolski, N Engl J Med. 2007;356:2457-2471) reported that rosiglitazone treatment is associated with a significant increase in myocardial infarction risk (p=0.03) and a borderline significant increase in the risk of death from cardiovascular causes (p=0.06). Nevertheless, the possibility that rosiglitazone might affect cardiovascular events should be evaluated by the ongoing trial Rosiglitazone Evaluated for Cardiac Outcomes and Regulation of Glycemia in Diabetes (RECORD). Interim findings early from RECORD did not show significant differences between the rosiglitazone and the control group regarding myocardial infarction and death from cardiovascular and any cause. Additional large-scale trials are awaited to clarify the of role TZDs in cardiovascular outcomes.

RESUMEN

Left ventricular hypertrophy (LVH) detected by ECG has been shown to be associated with a higher prevalence of ventricular arrhythmias in members of the general population, in a case-control series of hypertensive patients and in never-treated hypertensive patients. In-keeping with this, it has been observed that hypertension-induced LVH increases the risk of sudden cardiac death. Furthermore, a consistent bulk of data suggests antihypertensive therapy targeted at regression or prevention of electrocardiographic LVH may reduce the incidence of arrhythmias. In this regard, recent clinical trials showed that antihypertensive therapy may delay or prevent the occurrence of cardiac arrhythmias and sudden cardiac death in patients with hypertension. Porthan et al. hypothesized that an antihypertensive therapy might also rapidly affect ventricular repolarization and sought to investigate the short-term electrophysiological effects of four common antihypertensive drugs, represented by an angiotensin II receptor blocker (losartan), a beta-blocker (bisoprolol), a calcium channel blocker (amlodipine) and a thiazide diuretic (hydrochlorothiazide) in hypertensive men. Porthan et al. showed that losartan and bisoprolol favorably affected ventricular repolarization, with beneficial effects on ECG parameters of ventricular repolarization duration and heterogeneity. On the contrary, hydrochlorothiazide significantly increased repolarization heterogeneity, while amlodipine administration did not affect ECG repolarization measures. Thus, the observed findings suggest an intriguing hypothesis on the possible role of antihypertensive therapy in favouring or preventing cardiac arrhythmias.

RESUMEN

Atherosclerotic plaque plays a crucial role for the development of ischaemic diseases and, therefore, its early diagnosis and feature can help to reduce the incidence of cardiovascular events. Detection of early atherogenesis and characterization of plaque feature are the major end-points of research in cardiovascular imaging. Different techniques have been proposed as instrument for morphological and functional study of vascular walls. The purpose of this review is to underline the possibility of in vivo detecting the different stages of atherogenesis by using imaging techniques as well as their relationship with other risk factors in an attempt to assess the meaning of vascular lesions. Very promising results seem to emerge by the analysis of the literature on the subject, although different patterns are yet to be clarified.

RESUMEN

Epidemiological evidence supports the concept that diets rich in fruits and vegetables promote health and attenuate or delay the onset of cardiovascular disease (CVD). Although a variety of factors contribute to the beneficial effects of plant foods, much attention has been addressed to plant polyphenols. In this regard, in the daily Western diet, both black and green teas contribute to a relevant proportion of total phenol intake. The more abundant class of flavonoids that is present in teas is represented by flavanols, i.e., catechin, epicatechin, epigallocatechin, epicatechin gallate, and epigallocatechin gallate. Studies using animal models of atherosclerosis indicate that dietary flavonoid consumption delays atherosclerotic plaque development. Accordingly, an inverse association between tea intake and CVD has been demonstrated. Further, flavonoids can reduce endothelial dysfunction, i.e., the key step in the development of atherosclerosis. Concordantly, human data suggest that tea may reduce blood pressure levels. Despite this, although they often show that tea may have cardiovascular protective effects, results from epidemiological studies exploring the association between tea and health are controversial. Conflicting results may be caused by disparate study designs and flavonoid contents in different kinds of tea. Thus, because tea is a popular beverage worldwide, and several studies have shown that it is protective against CVD, further studies are needed to determine the role of tea in primary and secondary cardiovascular prevention.
