Arsenic, lead and cadmium concentration in food and estimated daily intake in the Cuban population and the health risks using a Total Diet Study.

This study estimates the intake of arsenic, lead and cadmium by the adult population (aged 18-91) of Cuba. The food consumption indices were obtained through 24-h dietary recall surveys applied to 450 people between October 2020 and March 2021. The Estimated Dietary Intake (EDI) of t-As (54.6 µg/day), Pb (118.5 µg/day) and Cd (35.1 µg/day) complied with Cuban legislation but was higher than the EDI for Cd established by the CONTAM Panel. The Target Hazard Quotients for the three contaminants were: iAs (0.220), Pb (0.409) and Cd (0.424), making the value of the Total Target Hazard Quotient 1.05, which indicates potential health risks for the population. Additionally, associated carcinogenic risks were: iAs (1.0·10-4), Pb (7.2·10-4) and Cd (25.9·10-4). Therefore, 10, 72 and 259 persons per 100,000 inhabitants are likely prone to developing cancer due to the ingestion of iAs, Pb and Cd, respectively.

Consensus on the detection and management of patients with depression and pain as an associated somatic symptom.

INTRODUCTION: Globally, depression is the most common psychiatric disorder and is frequently associated with somatic symptom disorders, including pain as a physical symptom. There is a current need to improve the detection and management of the individuals in which depression and pain coexist. Hence, the aim of this document is to provide recommendations in the diagnosis and management of patients with major depressive disorder (MDD) who have pain as a physical symptom (PPS), in order to reduce the variability of clinical practice. MATERIAL AND METHODS: The methodology used is based on the internationally recognized RAND/UCLA consensus method. The scientific committee, consisted of a group of eight multidisciplinary experts, defined 12 clinically relevant questions. After the systematic review of the literature, the scientific committee assessed the evidence and developed recommendations. The panel group with 15 participants validated these recommendations using a single Delphi round. To conclude, there was a final consensus meeting held to redefine with minor modifications the final recommendations. RESULTS: The scientific committee developed a total of 19 recommendations on the diagnosis and detection, impact of PPS in MDD, treatment of MDD with associated PPS, use of healthcare resources, additional recommendations, and care coordination of these patients. Globally, a substantial level of agreement (≥80%) was reached on all items during the Delphi round. All the 19 achieved consensus, seven of them (37%) were agreed with unanimity during the Delphi round. The recommendations with higher consensus were in relation to diagnosis, impact of PPS in MDD, treatment and use of healthcare resources. CONCLUSIONS: Currently, the evidence base for patients with MDD and PPS is still being developed and this consensus statement aims to bridge that gap by providing practical recommendations.

Murine macrophage-based iNos reporter reveals polarization and reprogramming in the context of breast cancer.

As part of the first line of defense against pathogens, macrophages possess the ability to differentiate into divergent phenotypes with varying functions. The process by which these cells change their characteristics, commonly referred to as macrophage polarization, allows them to change into broadly pro-inflammatory (M1) or anti-inflammatory (M2) subtypes, and depends on the polarizing stimuli. Deregulation of macrophage phenotypes can result in different pathologies or affect the nature of some diseases, such as cancer and atherosclerosis. Therefore, a better understanding of macrophage phenotype conversion in relevant models is needed to elucidate its potential roles in disease. However, there are few existing probes to track macrophage changes in multicellular environments. In this study, we generated an eGFP reporter cell line based on inducible nitric oxide synthase (iNos) promoter activity in RAW264.7 cells (RAW:iNos-eGFP). iNos is associated with macrophage activation to pro-inflammatory states and decreases in immune-suppressing ones. We validated the fidelity of the reporter for iNos following cytokine-mediated polarization and confirmed that reporter and parental cells behaved similarly. RAW:iNos-eGFP cells were then used to track macrophage responses in different in vitro breast cancer models, and their re-education from anti- to pro-inflammatory phenotypes via a previously reported pyrimido(5,4-b)indole small molecule, PBI1. Using two mouse mammary carcinoma cell lines, 4T1 and EMT6, effects on macrophages were assessed via conditioned media, two-dimensional/monolayer co-culture, and three-dimensional spheroid models. While conditioned media derived from 4T1 or EMT6 cells and monolayer co-cultures of each cancer cell line with RAW:iNos-eGFP cells all resulted in decreased fluorescence, the trends and extents of effects differed. We also observed decreases in iNos-eGFP signal in the macrophages in co-culture assays with 4T1- or EMT6-based spheroids. We then showed that iNos production is enhanced in these cancer models using PBI1, tracking increased fluorescence. Collectively, this work demonstrates that this reporter-based approach provides a facile means to study macrophage responses in complex, multicomponent environments. Beyond the initial studies presented here, this platform can be used with a variety of in vitro models and extended to in vivo applications with intravital imaging.

Sequential Biorefining of Bioactive Compounds of High Functional Value from Calafate Pomace (Berberis microphylla) Using Supercritical CO2 and Pressurized Liquids.

A biorefinery process was developed for a freeze-dried pomace of calafate berries (Berberis microphylla). The process consisted of extraction of lipophilic components with supercritical CO2 (scCO2) and subsequent extraction of the residue with a pressurized mixture of ethanol/water (1:1 v/v). scCO2 extracted oil from the pomace, while pressurized liquid extraction generated a crude extract rich in phenols and a residue rich in fiber, proteins and minerals. Response surface analysis of scCO2 extraction suggested optimal conditions of 60 °C, 358.5 bar and 144.6 min to obtain a lipid extract yield of 11.15% (d.w.). The dark yellow oil extract contained a good ratio of ω6/ω3 fatty acids (1:1.2), provitamin E tocopherols (406.6 mg/kg), and a peroxide index of 8.6 meq O2/kg. Pressurized liquid extraction generated a polar extract with good phenolic content (33 mg gallic acid equivalents /g d.w.), anthocyanins (8 mg/g) and antioxidant capacity (2,2-diphenyl-1-picrylhydrazyl test = 25 µg/mL and antioxidant activity = 63 µM Te/g). The extraction kinetics of oil by scCO2 and phenolic compounds were optimally adjusted to the spline model (R2 = 0.989 and R2 = 0.999, respectively). The solid extracted residue presented a fiber content close to cereals (56.4% d.w.) and acceptable values of proteins (29.6% d.w.) and minerals (14.1% d.w.). These eco-friendly processes valorize calafate pomace as a source of ingredients for formulation of healthy foods, nutraceuticals and nutritional supplements.

Humor interventions in psychotherapy and their effect on levels of depression and anxiety in adult clients, a systematic review.

Introduction: Humor as a valuable construct in psychology has been the subject of much discussion for many years and has received increased attention more recently in the field of positive psychology. However, empirical research on the application of humor in a clinical setting with depressed or anxious clients has been difficult to discover. Because of the potential benefits and the low costs of providing humorous interventions, our goal was to give an overview of the studies conducted in psychotherapy and to show the effect of humor on the levels of depression and anxiety symptoms. Furthermore, we wanted to assess the empiric support of humor as a clinical intervention in psychotherapy according to the SIGN system. Methods: We used the PRISMA guidelines. Because of the differences in the design of the 10 included studies, it was not possible to perform a meta-analysis. Results: Results from studies performed in seven different countries show that humorous interventions can have significant positive effects on symptoms of depression and anxiety. The results also confirm the prior observation that empirical research in the field is based on different designs with different populations and different methods of translating the abstract concept of humor into measurable observations. The results need to be considered with caution because of the methodological limitations of the research to date. Discussion: Some authors advocate for an integrative approach to continue research on humor in psychotherapy. It is our recommendation to first focus on the separate aspects of humor and to conduct research based on sound methodology. To initiate wider research to the application of humor in psychotherapy, we propose an approach to humorous interventions based on surprise and confusion which can help clients to search for an alternative framework to resolve the confusion and therefore promote taking on new perspectives and distancing themselves from the actual problem.

Inner Harmony as an Essential Facet of Well-Being: A Multinational Study During the COVID-19 Pandemic.

This study aimed to explore the role of two models of well-being in the prediction of psychological distress during the COVID-19 pandemic, namely PERMA and mature happiness. According to PERMA, well-being is mainly composed of five elements: positive emotions, engagement, relationships, meaning in life, and achievement. Instead, mature happiness is understood as a positive mental state characterized by inner harmony, calmness, acceptance, contentment, and satisfaction with life. Rooted in existential positive psychology, this harmony-based happiness represents the result of living in balance between positive and negative aspects of one's life. We hypothesized that mature happiness would be a more prominent protective factor during the present pandemic than the PERMA composite. A total of 12,203 participants from 30 countries responded to an online survey including the Depression Anxiety Stress Scale (DASS-21), the PERMA-Profiler, and the Mature Happiness Scale-Revised (MHS-R). Confirmatory factor analyses indicated that PERMA and mature happiness were highly correlated, but nonetheless, they represented two separate factors. After controlling for demographic factors and country-level variables, both PERMA Well-being and MHS-R were negative predictors of psychological distress. Mature happiness was a better predictor of stress, anxiety, and general distress, while PERMA showed a higher prediction of depression. Mature happiness moderated the relation between the perceived noxious effects of the pandemic and all markers of distress (depression, anxiety, stress, and total DASS-21). Instead, PERMA acted as a moderator in the case of depression and stress. These findings indicate that inner harmony, according to the mature happiness theory, is an essential facet of well-being to be taken into consideration. The results of this study can also orient policies aimed to alleviate the negative effects of the pandemic on mental health through the promotion of well-being.

[Evidence-Based Psychological Treatments for Adults: A Selective Review]

Evidence-Based Psychological Treatments for Adults: A Selective Review. BACKGROUND: Psychological treatments have shown their efficacy, effectiveness, and efficiency in dealing with mental disorders. However, considering the scientific knowledge generated in recent years, in the Spanish context, there are no updating studies about empirically supported psychological treatments. The main goal was to carry out a selective review of the main empirically supported psychological treatments for mental disorders in adults. METHOD: Levels of evidence and degrees of recommendation were collected based on the criteria proposed by the Spanish National Health System (Clinical Practice Guidelines) for different psychological disorders. RESULTS: The results indicate that psychological treatments have empirical support for the approach to a wide range of psychological disorders. These levels of empirical evidence gathered range from low to high depending on the psychological disorder analysed. The review indicates the existence of certain fields of intervention that need further investigation. CONCLUSIONS: Based on this selective review, psychology professionals will be able to have rigorous, up-to-date information that allows them to make informed decisions when implementing empirically based psychotherapeutic procedures based on the characteristics of the people who require help.

Cariprazine in Three Acute Patients with Schizophrenia: A Real-World Experience.

There are still some unmet needs in the treatment of schizophrenia like the persistence of negative symptoms. Cariprazine is a new-generation antipsychotic with partial agonism of the dopamine receptors, distinct from other antipsychotics by its 10 times greater affinity for D3 receptors. This mechanism of action could be especially favorable on patients with predominant negative symptoms. This report is showing three clinical cases of acute schizophrenia exacerbation that required hospitalization and were successfully treated with cariprazine. All of them had predominant positive symptoms and two of them had substance use. Efficacy of cariprazine was also crucial on negative and cognitive symptoms with excellent tolerability.

Psychological Impact of COVID-19 Confinement and Its Relationship with Meditation.

The objective of this study was to evaluate the psychological impact of confinement due to the COVID-19 pandemic, considering any protective factors, such as the practice of meditation or self-compassion, and their relationship with different lifestyles and circumstances of adults residing in Spain. A cross-sectional study was done using an anonymous online survey in which 412 participants filled out the Depression, Anxiety and Stress Scale-2; the Impact of Events Scale; and the Self-Compassion Scale-Short Form, reporting severe symptomatology of posttraumatic stress and mild anxiety and depression. Quality of cohabitation and age were found to be key variables in the psychological impact of confinement. The impact of confinement was more negative for those who reported very poor cohabitation as opposed to very good (F (3, 405) = 30.75, p ≤ 0.001, d = 2.44, r = 0.054) or for those under 35 years of age compared to those over 46 (F (2, 409) = 5.14, p = 0.006, d = 0.36). Practicing meditation was not revealed as a protective factor, but self-compassion was related to better cohabitation during confinement (F (3, 403) = 11.83, p ≤ 0.001, d = 1.05). These results could be relevant in designing psychological interventions to improve coping and mental health in other situations similar to confinement.

Spanish adaptation of the Personal Meaning Profile-Brief: Meaning in life, psychological well-being, and distress / Adaptación española del Personal Meaning Profile-Brief: sentido en la vida, bienestar y malestar psicológico

BACKGROUND/OBJECTIVE: This study aimed to adapt the Personal Meaning Profile-Brief (PMP-B) to the Spanish-speaking population and investigate its psychometric properties. The PMP-B is a 21-item instrument that assesses meaning in life through seven sources: relationship, intimacy, achievement, self-acceptance, self-transcendence, fair treatment, and religion. METHOD: Participants were 546 Spanish adults comprised of a community sample (n = 171) and university students (n = 375). The PMP-B, the Ryff's Scales of Psychological Well-Being, and the Depression Anxiety Stress Scale were administrated. RESULTS: The PMP-B showed a bifactor structure with one general factor and seven subfactors. Measurement invariance was found across age, gender, and samples. Internal consistency and test-retest reliability were generally good. Older people showed higher PMP-B scores than younger people. The PMP-B scores, especially relational sources of meaning, were positively associated with psychological well-being and negatively related to psychological distress, mainly to depression. CONCLUSIONS: The validity evidence gathered in this study supports the reliable use of the PMP-B to measure meaning in life. The PMP-B can be a noteworthy contribution to the meaning-centered research

The Uruguayan semen donor population: A twenty-eight-year retrospective study.

Several studies have reported a global decline in seminal quality over the years. The objective of this study was to describe the semen donor population of Uruguay through comparing data of successive samples banked by the same donors and the analysis of their semen and physical characteristics, ancestry origin and educational level. A total of 3,449 ejaculated samples collected from 71 donors, cryobanked between 1989 and March 2017 at Fertilab, were analysed. Results revealed a mean age of 23.90 ± 3.98 years, an average weight of 74.95 ± 1.09 kg and a mean height of 1.78 ± 0.06 m. The majority of the donors trace their origin to Europe (74.65%, 53/71) and 66.19% (47/71) have a level of education higher than secondary school. We observed longitudinal differences in two parameters, that is sperm concentration and semen volume. Sperm concentration declined, while semen volume increased significantly over the 28-year period. The results of the present study are in accordance with that of previous articles that also reported a decline in sperm concentration over time. However, no differences were observed in total sperm number per ejaculate due to the increase in semen volume values, thus reflecting no real changes in sperm production over time.

Diminished emotional expression in schizophrenia: an interdisciplinary approach based on behavioral interventions.

BACKGROUND: Negative symptoms represent the main cause of disability in schizophrenia, having recently been grouped into two general dimensions: avolition and diminished emotional expression, which includes affective flattening and alogia. The aim of this study was to explore the response of these two symptoms to a set of behavioral interventions based on contingency management, performed in an interdisciplinary context. METHOD: Behaviors of interest were monitored and evaluations before and after the treatment were performed on 9 schizophrenic inpatients with persistent negative symptoms. The program included 12 group double sessions aimed at developing facial expression and verbal communication, and a nursing care plan to generalize and strengthen these behaviors synergistically. RESULTS: there were appreciable differences in facial expression, which were less clear for alogia. The clinical evaluation using PANSS-N did not find notable differences at group level, but the nursing assessment using NOC indicators did. CONCLUSIONS: although difficult to modify, negative symptoms are not insensitive to the influence of behavioral interventions. Specific psychological interventions that address negative symptoms as a priority focus of attention and care need to be promoted and developed, particularly when considering the crucial role of context in their progression.

Rethinking Schizophrenia in the Context of the Person and Their Circumstances: Seven Reasons.

We know a great deal about schizophrenia, but the current state of the art is one of uncertainty. Researchers are confused, and patients feel misunderstood. This situation has been identified as due largely to the fact that the dominant neurobiological perspective leaves out the person. The aim of the present article is to review and integrate a series of clinical, phenomenological, historical, cultural, epidemiological, developmental, epigenetic, and therapeutic phenomena in support of a suggestion that schizophrenia is above all a disorder of the person rather than of the brain. Specifically, we review seven phenomena, beginning with the conception of schizophrenia as a particular disorder of the self. We continue by looking at its recent origin, as a modern phenomenon, its juvenile onset, related to the formation of the self, the better prognosis in developing countries compared to developed countries, and the high incidence of the disorder among migrants. In the context of these phenomena of a marked socio-cultural nature, we consider the so-called "genetic myth," according to which schizophrenia would have a genetic origin. On reviewing the current genetic emphasis in the light of epigenetics, it emerges that the environment and behavior recover their prominent role in the vicissitudes of development. The seventh reason, which closes the circle of the argument, concerns the role of interpersonal "chemistry" in recovery of the sense of self.

The relationship of depersonalization and absorption to hallucinations in psychotic and non-clinical participants.

The purpose of this study was to examine the relationship between dissociative variables and hallucinations, or predisposition to hallucinations, respectively, in patients with psychoses and non-clinical participants, controlling for any possible effect of emotional variables and age. Three groups were formed for this purpose: patients diagnosed with schizophrenia with auditory hallucinations at the time of study, healthy participants prone to hallucinations, and healthy participants not prone to hallucinations. The final sample was 318 participants with a mean age of 21.41 years (SD: 5.78) and a male-to-female ratio of 67:251. All participants were given the Tellegen Absorption Scale, the Cambridge Depersonalization Scale and the Metacognitions Questionnaire. The results showed that patients with psychosis had higher levels of depersonalization than participants prone and not prone to hallucinations. Prone participants showed higher levels of absorption than patients with psychosis and healthy participants with no proneness to hallucinations. Finally, a multinomial logistic regression analysis showed that depersonalization increased the probability of belonging to the group of patients with psychosis and auditory hallucinations, and absorption in the group prone to hallucinations. The conclusions discuss the importance of dissociative variables in understanding the etiology of hallucinations and consider the possibility that different psychological processes may occur in healthy participants prone to hallucinations and in hallucinations in persons with psychoses.

Relationship between self-focused attention and mindfulness in people with and without hallucination proneness

The purpose of this work was to study the relationship between self-focused attention and mindfulness in participants prone to hallucinations and others who were not. A sample of 318 healthy participants, students at the universities of Sevilla and Almería, was given the Launay-Slade Hallucinations Scale-revised (LSHS-R, Bentall & Slade, 1985). Based on this sample, two groups were formed: participants with high (n = 55) and low proneness (n = 28) to hallucinations. Participants with a score higher than a standard deviation from the mean in the LSHS-R were included in the high proneness group, participants with a score lower than a standard deviation from the mean in the LSHR-R were included in the second one. All participants were also given the Self-Absorption Scale (SAS, McKenzie & Hoyle, 2008) and the Southampton Mindfulness Questionnaire (SMQ, Chadwick et al., 2008). The results showed that participants with high hallucination proneness had significantly higher levels of public (t(80) = 6.81, p < .001) and private (t(77) = 7.39, p < .001) self-focused attention and lower levels of mindfulness (t(81) = -4.56, p < .001) than participants in the group with low hallucination proneness. A correlational analysis showed a negative association between self-focused attention (private and public) and mindfulness (r = -0.23, p < .001; r = -0.38, p < .001 respectively). Finally, mindfulness was found to partly mediate between self-focused attention and hallucination proneness. The importance of self-focused attention and mindfulness in understanding the etiology of hallucinations discussed and suggest some approaches to their treatment (AU)
