RESUMO

Trust in governmental organizations is a crucial factor in terms of encouraging people to conform to public health regulations, such as those recommended to slow down the spread of SARS-CoV-2. However, trust in governmental organizations tends to decline over time, reducing the compliance with public health regulations. This study aimed at exploring, first, the role of future anxiety and fatigue as serial mediators of the relationship between trust in governmental organizations and protective behaviors, and, secondly, the role of Covid-19 risk perception as a moderator between fatigue and protective behaviors. A total of 948 Italian participants (302 males and 646 females), ranged from 18 to 80 years (M = 27.20, SD = 11.01), answered an online survey during the second wave of the Covid-19 outbreak. A moderated serial mediation model was performed using a structural equation modeling. The results indicate that: (1) a higher trust in Italian governmental organizations was associated with a greater compliance in terms of adopting protective behaviors; (2) a lower trust in Italian governmental organizations increased anxiety about the future which, in turn, raised levels of fatigue, leading, finally, to a reduction in the levels of protective behaviors; and (3) as the perceived risk related to Covid-19 increased, the effect of fatigue on protective behaviors decreased. The findings of the current study may provide indications for public health policy on how to increase compliance with the recommended behaviors to be adopted in order to decrease the spread of the SARS-CoV-2.

RESUMO

Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) represents the most frequent form of CAH and of 46, XX disorder of sex development in female newborns. In the majority of cases, particularly in developed countries, female patients suffering from the classic forms of CAH reach the diagnosis at birth or in the early childhood, allowing a prompt treatment with a correct gender assignment. The current manuscript describes an unusual case of an Italian 46-year-old woman, homeborn in the 60s, receiving an extraordinarily late diagnosis of simple virilising classic form of CAH due to 21-OHD, determining a relevant impairment of both physical and psychosexual development. The patient presented primary amenorrhea, height under target, overweight with visceral adiposity, hypercholesterolemia and insulin resistance, hirsutism with a typical male-pattern hair growth, external genital ambiguity, and a severe impairment in the entire series of psychological dimensions, particularly severe depressive symptoms, together with gender dysphoria relative to the female gender assigned at birth, cross-gender behaviours, and body image discomfort, which were associated with homosexual orientation, and sexual dysfunction. Following diagnosis and glucocorticoid (GC) replacement therapy, the hyperandrogenism control and familial and socio-cultural factors changes, particularly, living alone and the interruption of social isolation, were accompanied by menarche appearance, improvement in hirsutism and metabolic profile, and a resolution in all psychological dimensions, depressive symptoms, and gender dysphoria. The patient began to perceive homosexual orientation without discomfort, and ameliorating sexual function. Few cases of female patients with CAH due to 21-OHD receiving an extremely delayed diagnosis have been published. However, to the best of our knowledge, this is the first case including a complete psychosexual assessment at diagnosis with a detailed re-evaluation after 5 years of disease treatment.

RESUMO

Venepuncture and peripheral intravenous cannulation are two of the most commonly paediatric performed medical procedures in many healthcare settings. These procedures can cause significant pain and distress at any age, during childhood, so appropriate management is strongly recommended. This review examines the evidence related to pain and distress management during venepuncture and peripheral intravenous cannulation, including preparing the environment, assessing and preparing patients, parental involvement and psychological and pharmacological interventions. It specifically refers to neonates, children with cognitive impairment and children with difficult intravenous access. We provide a brief management strategy, with easily implemented techniques to improve daily practice.

RESUMO

Background: Non-binary and genderqueer (NBGQ) people are those who do not identify within the gender binary system (male vs. female), not falling exclusively in man/male or woman/female normative categories. A higher proportion of NBGQ people is usually found within young persons. This population is marginalized and, as such, is at risk of stigmatization and of developing negative health outcomes. As literature on the health of NBGQ people is sparse, this study aims at systematically review the limited studies on this field. Methods: The research questions which guided the systematic review were: (1) What are the differences in the health levels between NBGQ and binary transgender (BT) individuals? (2) What are the differences in the health levels between NBGQ and cisgender individuals? (3) Which medical and psychological interventions are most suitable for improving NBGQ health? According to PRISMA guidelines, a systematic search was conducted in PubMed, PsycInfo, Web of Science, and Google Scholar. Results: Eleven studies met the inclusion criteria for the current systematic review. Among them, 9 were focused on the health differences between NBGQ and BT individuals, 4 of the latter and 1 individually were focused on the health differences between NBGQ and cisgender individuals, and 1 was focused on the evaluation of health outcomes related to medical procedures. No studies assessed psychological interventions aimed at improving health in NBGQ individuals. All studies were cross-sectional, did not generally recruit a large sample of NBGQ individuals, and used non-probability sample design. Results related to the difference in health between NBGQ and BT were mixed; indeed, some found a better health status while others a worse one. Results related to the differences in health between NBGQ and cisgender highlighted higher health needs in NBGQ than in BT individuals. The only study analyzing the effects of medical interventions on health found that NBGQ female-assigned at birth individuals improved their quality of life after chest surgery. Conclusions: Although scholars are starting to pay attention to the NBGQ health, research needs to be expanded both in terms of methodology and research contents. Clinical, health-related social policies, and research recommendations in this field are reported.

RESUMO

Despite the rapid increase in lesbian and gay (LG) people who desire and decide to become parents, LG childless individuals may encounter serious obstacles in the parenthood process, such as minority stress. Notwithstanding, the psychological processes by which prejudice events might affect the desire to become parents are still understudied. As an extension of the minority stress theory, the psychological mediation framework sheds light on these psychological processes, as it encompasses a more clinical view of stress. Within this framework, the current study aimed at assessing the role of prejudice events in affecting parenting desire in 290 childless Italian LG individuals (120 lesbians and 170 gay men), as well as the role of internalized heterosexism and sexual orientation concealment in mediating the relationship between prejudice events and parenting desire. The results suggest that only in lesbians prejudice events were negatively associated with parenting desire, and that sexual orientation concealment and internalized heterosexism were also negatively associated with parenting desire. Furthermore, sexual orientation concealment, and not internalized heterosexism, mediated the relationship between prejudice events and parenting desire in lesbians, but not gay men. The findings have important implications for clinical practice.

RESUMO

Metacognitive skills and agency are among the main psychological abilities a clinical psychologist should have. This study aimed to assess the efficacy of group psychodynamic counselling as a clinical training device able to enhance metacognitive skills and agency in final-year undergraduates in clinical psychology within an educational context. Thirty-three final-year students of clinical psychology participated in an experiential laboratory lasting two months. Participants completed measures regarding metacognitive skills and agency at pre-, post-treatment, and 3-month follow-up assessment. The results suggested that group psychodynamic counselling made students feel more capable of recognizing emotional states, understanding causal relationships, inferring mental states of others in terms of beliefs, desires, intentions, and expectations, and thinking critically. Furthermore, the group psychodynamic counselling helped students to feel more able to derive pathways to desired goals and to motivate themselves via agency thinking to use those pathways. Thus, the study confirmed the efficacy of group psychodynamic counselling as a clinical training device able to enhance metacognitive skills and agency in future clinical psychologists.

RESUMO

BACKGROUND: Hereditary angioedema with C1-inhibitor deficiency (C1-INH-HAE) is characterized by recurrent edema of unpredictable frequency and severity. Stress, anxiety, and low mood are among the triggering factors most frequently reported. Impaired regulation and processing of emotions, also known as alexithymia, may influence outcomes. The aim of this study was to confirm the presence of alexithymia and stress in children with C1-INH-HAE, to determine whether they are also present in children affected by other chronic diseases, and to investigate their relationship with C1-INH-HAE severity. Data from children with C1-INH-HAE (n = 28) from four reference centers in Italy were compared with data from children with type 1 diabetes (T1D; n = 23) and rheumatoid arthritis (RA; n = 25). Alexithymia was assessed using the Alexithymia Questionnaire for Children scale; perceived stress was assessed using the Coddington Life Event Scale for Children (CLES-C). RESULTS: Mean age (standard deviation [SD]) in the C1-INH-HAE, T1D, and RA groups was 11.8 (3.3), 11.7 (2.9), and 11.1 (2.6) years, respectively. Mean C1-INH-HAE severity score was 5.9 (2.1), indicating moderate disease. Alexithymia scores were similar among disease groups and suggestive of difficulties in identifying and describing emotions; CLES-C scores tended to be worse in C1-INH-HAE children. C1-INH-HAE severity was found to correlate significantly and positively with alexithymia (p = 0.046), but not with perceived stress. Alexithymia correlated positively with perceived stress. CONCLUSIONS: Alexithymia is common in children with chronic diseases. In C1-INH-HAE, it may result in increased perceived stress and act as a trigger of edema attacks. Comprehensive management of C1-INH-HAE children should consider psychological factors.

RESUMO

Transgender and gender nonconforming (TGNC) people are a highly-stigmatized population. For this reason, they might internalize society's normative gender attitudes and develop negative mental health outcomes. As an extension of the minority stress model, the psychological mediation framework sheds light on psychological processes through which anti-transgender discrimination might affect mental health. Within this framework, the current study aimed at assessing in 149 TGNC Italian individuals the role of internalized transphobia as a mediator between anti-transgender discrimination and mental health, considering resilience as the individual-level coping mechanism buffering this relationship. The results suggest that both indicators of internalized transphobia (i.e., shame and alienation) mediate the relationship between anti-transgender discrimination and depression, while only alienation mediates the relationship between anti-transgender discrimination and anxiety. Furthermore, the results suggest that the indirect relation between anti-transgender discrimination and anxiety through alienation is conditional on low and moderate levels of resilience. Findings have important implications for clinical practice and psycho-social interventions to reduce stigma and stress caused by interpersonal and individual stigma.

RESUMO

PURPOSE: To investigate the moderating role of resilience in the relationship between affective disorders and Health-Related Quality of Life (HRQoL) for adolescents and young adults with multiple sclerosis (MS). METHODS: A quantitative methodology was adopted. Fifty-three adolescents and young adults were interviewed to assess resilience as a personality trait (Ego-Resiliency Scale) and resilience as an interactive competence (CYRM-28), Health-Related Quality of Life (PedsQL 4.0), depression and anxiety (BDI-II and STAI-Y). RESULTS: Affective disorders, both depression (ß = -.38, p < .001) and anxiety (State ß = -.35, p < .001; Trait ß = -.41, p < .001), were negatively associated with HRQoL. Data also showed that the resilience competencies using Individual (ß = .22, p < .001) and relational resources (ß = .12, p < .05) are significantly associated HRQoL. According to the regression analyses, we tested the moderating role of resilience competence using individual resources on the relationship between the Depression Cognitive Factor and Emotional Functioning. Data show that in step 2 of the regression analysis, we obtained a variation of ß = -.45 (p < .001) to ß = -.30 (p < .001) in the dimension for the Depression Cognitive Factor. The Sobel test showed that the moderating effect of resilience was significant regarding the increase in R2 (p < .01). CONCLUSIONS: Resilience competence using individual resources moderates the relationship between the Depression Cognitive Factor and Emotional Functioning in adolescents with MS. Our study suggests that to improve well-being for adolescents with MS resilience could play a key role.

RESUMO

Purpose: Understanding how transgender people, who committed criminal offenses and are detained in prison, produce a narrative representation of self within different prison contexts. More specifically, this study has been based on two sub-aims: On a paradigmatic level, it has been aimed at critically investigating how the discursive positioning among the Self and the Other might promote the internalization of positive and/or negative attitudes toward the self. On a pragmatic level, it intends to offer some suggestions for goals and strategies of psychological counseling with these inmates inside such highly institutionalized contexts. Method and Materials: In total, 23 in-depth interviews were conducted with transgender women detained in either female or male prison contexts in Italy and Brazil. The lexical, semantic, and semiotic structure of the transcribed interviews has been investigated by adopting the quali-quantitative software Iramuteq for performing statistical text-mining analysis. Frequency, correspondences, and distribution of the most representative utterances across the corpus of data have been accessed and critically analyzed. Results: The findings showed that transgender inmates in Brazil made repeated use of the adverb "not," while the verb "exist" became the most representative word for the Italian sample. In Brazil, indeed, transgender women assumed masculine-driven behavior due to a common imprisonment with cis-gender men. On the contrary, transgender women in Italy are detained in protected sections, where they are allowed to wear female clothing and continue hormonal treatments. Surprisingly, transgender inmates in Italy suffered more violence in a female sector when compared to exclusively male jails. Conclusions: Transgender people represent a challenge for prison administration because it is not clear in which penitentiary context they should be detained. They should receive special attentions in order to face their special needs, which are radically different when compared to other typologies of inmates. Within penitentiary contexts, psychological counseling with transgender women should pay a special attention to the several psycho-social dimensions of this existential condition. In particular, psychological counselors should consider its inner complex articulation within different social, cultural and normative contexts.

RESUMO

INTRODUCTION: Although attachment theory has been recognized as one of the main reference for the study of the general wellbeing, little research has been focused on the attachment styles of transgender people. Attachment styles are deeply influenced by the earliest relationships with caregivers, which, for gender nonconforming children, are often characterized by parental rejection. Consequently, transgender children and adults likely internalize societal stigma, developing internalized transphobia. The current research was aimed to explore the link between adult attachment and internalized transphobia. METHOD: 25 male-to-female (MtF) and 23 female-to-male (FtM) transgender people participated in the survey filling in two self-report questionnaires: the Attachment Style Questionnaire and the Transgender Identity Survey. A cluster analysis, T-Test and multiple regression analysis were conducted to explore the link between attachment styles and internalized transphobia. RESULTS: A greater prevalence of secure attachment styles was detected. Participants with secure attachment styles reported higher levels of positive transgender identity than those with insecure attachment styles. Secure attachment styles significantly affect positive transgender identity, while insecure attachment styles influence internalized transphobia. CONCLUSIONS: A clinical focus on the redefinition of the Internal Working Models of transgender people can inform psychologically-focused interventions, which transgender people can benefit from.

RESUMO

OBJECTIVE: To identify historical and clinical findings at emergency department presentation associated with severe H1N1 outcome in children presenting with influenza-like illness. DESIGN: Multicentre retrospective case-control study. SETTING: 79 emergency departments of hospitals associated with the Pediatric Emergency Research Networks in 12 countries. PARTICIPANTS: 265 children (<16 years), presenting between 16 April and 31 December 2009, who fulfilled Centers for Disease Control and Prevention criteria for influenza-like illness and developed severe outcomes from laboratory confirmed H1N1 infection. For each case, two controls presenting with influenza-like illness but without severe outcomes were included: one random control and one age matched control. MAIN OUTCOME MEASURES: Severe outcomes included death or admission to intensive care for assisted ventilation, inotropic support, or both. Multivariable conditional logistic regression was used to compare cases and controls, with effect sizes measured as adjusted odds ratios. RESULTS: 151 (57%) of the 265 cases were male, the median age was 6 (interquartile range 2.3-10.0) years, and 27 (10%) died. Six factors were associated with severe outcomes in children presenting with influenza-like illness: history of chronic lung disease (odds ratio 10.3, 95% confidence interval 1.5 to 69.8), history of cerebral palsy/developmental delay (10.2, 2.0 to 51.4), signs of chest retractions (9.6, 3.2 to 29.0), signs of dehydration (8.8, 1.6 to 49.3), requirement for oxygen (5.8, 2.0 to 16.2), and tachycardia relative to age). CONCLUSION: These independent risk factors may alert clinicians to children at risk of severe outcomes when presenting with influenza-like illness during future pandemics.

RESUMO

OBJECTIVES: Objectives of the Pediatric Emergency Research Network's (PERN's) meeting included (1) learn about each of the participating network's missions, goals, and infrastructure; (2) share important contributions each network has made to the creation of new knowledge; (3) discuss "best practices" to improve each network's effectiveness; and (4) explore the potential for a collaborative research project as proof of concept that would help us promote quality of care of the acutely ill and injured child/youth globally. METHODS: In October 2009, a multiday meeting was attended by 18 delegates representing the following pediatric emergency medicine research networks: Pediatric Emergency Medicine Collaborative Research Committee (United States), Pediatric Emergency Care Applied Research Network (United States), Pediatric Emergency Research of Canada (Canada), Paediatric Research in Emergency Departments International Collaborative (Australia and New Zealand), and Research in European Pediatric Emergency Medicine (15 countries in Europe and the Middle East). RESULTS: The inaugural meeting of PERN demonstrated that there is a common desire for high-quality research and the dissemination of this research to improve health and outcomes of acutely ill and injured children and youths throughout the world. Presently, the PERN group is in the final stages of developing a protocol to assess H1N1 risk factors with the collection of retrospective data. CONCLUSIONS: Several members of PERN will be gathering at the International Conference on Emergency Medicine in Singapore, where the group will be presenting information about the H1N1 initiative. The PERN group is planning to bring together all 5 networks later in 2010 to discuss future global collaborations.

RESUMO

OBJECTIVES: The aim of this paper is to enlight the role of endorectal ultrasonography in the preoperative staging of rectal cancer. METHODS: 83 patients having rectal cancer and candidates to surgery were studied with endorectal ultrasonography with a probe at a frequency up to 7.5 MHz probe. Eighteen patients were diagnosed with a cancer at A stage, 38 with a neoplasia at B stage and 37 at C stage. RESULTS: In all patients the examination revealed an involvement of the rectal muscular tunica. Sixtyseven patients presented mesorectal invasion, 17 patients showed the involvement of adjoining structures, and 27 patients presented pathological lymph nodes. CONCLUSIONS: Endorectal ultrasonography allows to distinguish patients having rectal cancer limited to the mucosa or invading sub-mucosa regions from those having a more indepth invasion. Apart from this, endorectal ultrasonography is not able of discriminate reactive lymph nodes from metastatic ones.

RESUMO

OBJECTIVES: Endorectal ultrasound was compared with magnetic resonance imaging (MRI) in the preoperative staging for patients with Rectal Cancer. Diagnostic accuracy was assessed with regards to the factors that might influence the risk of local relapse such as T, N and CRM (circumferential resection margin). METHODS: From January 2006 to April 2010, 64 patients with rectal cancer were studied preoperatively either by means of MRI scan of the pelvis or endorectal ultrasound scan in order to assess the intramural extension. For 30 out of 64 patients both methods were used (comparing instrumental with histopathological data) while for 34 patients over 64 only ultrasound scan was used. RESULTS: Endorectal ultrasound resulted to be more reliable in defining the T (parietal infiltration of the tumor) whereas MRI better defined CRM. CONCLUSIONS: Both methods are reliable and complementary enabling an accurate staging of patients with rectal cancer.

RESUMO

Experimental and clinical data indicate that tumor progression and malignancy are associated with increased angiogenesis and higher Ki-67 proliferation rate. Furthermore, increased angiogenesis and higher Ki-67 proliferation rate are associated with a poor prognosis, in both solid and hematological malignancies. However, no data have been published concerning the relationship between angiogenesis and Ki-67 proliferation rate in canine non-Hodgkin's lymphoma (NHL), a neoplasm that shares several biological and clinical characteristics with human NHL. This study has evaluated the relationship between angiogenesis and Ki-67 proliferation rate in a series of 58 canine NHL. Results showed that microvascular density (MVD), endothelial area (EA) and Ki-67 (MIB-1) are significantly correlated and that all the above indexes paralleled with the malignancy degree of NHL. These data suggest a biological link between angiogenesis and Ki-67 proliferation rate in canine NHL, which represents an interesting model to study the role of angiogenesis and proliferative activity as inter-species pathways of tumoral malignancy and biological aggressiveness.

RESUMO

Angiogenesis is important in the growth and progression of solid tumours. The main pro-angiogenic factor, namely vascular endothelial growth factor (VEGF), also known as vascular permeability factor, is a potent angiogenic cytokine that induces mitosis and also regulates the permeability of endothelial cells. The soluble isoform of VEGF is a dimeric glycoprotein of 36-46 kDa, induced by hypoxia and oncogenic mutation and it binds to two specific tyrosine-kinase receptors: VEGF-1 (flt-1) and VEGF-2 (KDR/flk1). An increase in VEGF expression in tumour tissue or some blood compartments (i.e. serum or plasma) has been found in solid and haematological malignancies of various origins and is associated with metastasis formation and poor prognosis. Bevacizumab, a recombinant humanised monoclonal antibody developed against VEGF, binds to soluble VEGF, preventing receptor binding and inhibiting endothelial cell proliferation and vessel formation. Pre-clinical and clinical studies have shown that bevacizumab alone or in combination with a cytotoxic agent decreases tumour growth and increases median survival time and time to tumour progression. Bevacizumab is the first anti-angiogenetic treatment approved by the American Food and Drug Administration in the first-line treatment of metastatic colorectal cancer. It has shown preliminary evidence of efficacy for breast, non-small-cell lung, pancreatic, prostate, head and neck and renal cancer as well as haematological malignancies. Common toxicities associated with bevacizumab include hypertension, proteinuria, bleeding episodes and thrombotic events. This review summarises the critical role of VEGF and discusses the data available on bevacizumab, from the humanisation of its parent murine monoclonal antibody (mAb) A.4.6.1 to its use in cancer clinical trials.

In adulthood, choledochal cysts are often surprisingly discovered during cholecystectomy. We report here on a case of an unsuspected congenital type-IA biliary cyst, according to Todani's classification encountered during laparoscopic cholecystectomy in a 30-year-old woman complaining of acute abdominal pain with an unremarkable preoperative workup. The well-known risk of developing cystic cancer, mainly in the adult, means that an excisional operation is indicated to prevent such complications. Cyst excision and Roux-en-Y hepaticojejunostomy is the definitive treatment of choice, performed at a later stage after radiological and endoscopic confirmation, and after obtaining the patient's consent. Cholangio-MR, and ERCP have proved to be extremely useful for adequate identification of this kind of lesion.

RESUMO

Vascular endothelial growth factor (VEGF) is known to play a key role in tumour angiogenesis. Our preliminary published data suggest that plasma-activated platelets rich (P-APR) rather than other plasma compartments (i.e. plasma, plasma-platelets poor) or serum is the more suitable blood fraction for measuring VEGF in a miscellaneous series of gastrointestinal cancer patients. The aim of this confirmatory study was to assess VEGF in P-APR blood compartments of 30 healthy control subjects (HCS) and a homogeneous series of 62 colorectal cancer patients (CRCP), prospectively collected, to evaluate its possible clinical-biological significance. Samples of plasma (P) in both sodium citrate (SC) and sodium citrate-theophylline-adenosine-dipyridamole (CTAD) were collected from venous blood. After the centrifugation and separation methods VEGF levels were detected by ELISA in P-APR. The best differentiation between HCS and CRCP in VEGF level was seen for P-APRCTAD (median value: 255 pg/ml versus 142 pg/ml; p=0.000 by Mann-Whitney U test). No significant correlation among the P-APR VEGF concentrations and the main clinical pathological features was found. We suggest that P-APRCTAD fraction, obtained according to well standardised conditions, could represent the suitable blood compartment for the assessment of VEGF as marker of malignant intestinal transformation.
