RESUMO

OBJECTIVES: The present pre-registered study examined the reciprocal day-to-day associations between global self-esteem and self-concept clarity and their incremental validity with respect to daily life satisfaction, positive affect, and negative affect. METHODS: We used intensive longitudinal data from 153 adult workers (45.1% women), over a period of 31 days. Data were analyzed using dynamic structural equation modeling. RESULTS: Results attested higher global self-esteem and self-concept clarity mean levels for older vs. younger participants, and lower global self-esteem and self-concept clarity variability for older vs. younger participants. Furthermore, global self-esteem and self-concept clarity were correlated at a cross-sectional daily level, yet only self-concept clarity states positively predicted subsequent global self-esteem states, while global self-esteem states did not predict subsequent self-concept clarity states. Daily global self-esteem and daily self-concept clarity further predicted subsequent daily higher life satisfaction and positive affect, respectively. CONCLUSION: Overall, our findings shed light on the short-term relationships linking global self-esteem and self-concept clarity, pointing to their discriminant validity in predicting individuals' subjective well-being.

RESUMO

The Spinal Muscular Atrophy (SMA) gene SMN was recently duplicated (SMN1 and SMN2) in higher primates. Furthermore, invasion of the locus by repetitive elements almost doubled its size with respect to mouse Smn, in spite of an almost identical protein-coding sequence. Herein, we found that SMN ranks among the human genes with highest density of Alus, which are evolutionary conserved in primates and often occur in inverted orientation. Inverted repeat Alus (IRAlus) negatively regulate splicing of long introns within SMN, while promoting widespread alternative circular RNA (circRNA) biogenesis. Bioinformatics analyses revealed the presence of ultra-conserved Sam68 binding sites in SMN IRAlus. Cross-link-immunoprecipitation (CLIP), mutagenesis and silencing experiments showed that Sam68 binds in proximity of intronic Alus in the SMN pre-mRNA, thus favouring circRNA biogenesis in vitro and in vivo. These findings highlight a novel layer of regulation in SMN expression, uncover the crucial impact exerted by IRAlus and reveal a role for Sam68 in SMN circRNA biogenesis.

RESUMO

OBJECTIVES: We examined the mental health of mothers after unaccompanied birth (unaccompanied group, UG) due to COVID-19-related visiting bans and compared the data with a control group with accompanied birth (AG). Additionally, a distinction was made between caesarean section (CS) and vaginal birth (VB), as existing research indicates a higher risk for mental distress after CS. METHODS: The cross-sectional study included 27 mothers in the UG and 27 matched controls (AG). Anxiety, depression, postpartum traumatic stress symptoms (PTSS), and psychological well-being were assessed. Additionally, emotions and attitudes related to the restrictions were measured by self-developed items. RESULTS: Psychological distress was high especially in the UG (anxiety: 23%, PTSS: 34.6%, low well-being: 42.3%, depression: 11.5%). Mothers in the AG had lower psychological distress than those in the UG, but still had enhanced rates of PTSS (11.1%) and diminished well-being (22.2%). In both groups, women with CS reported higher anxiety and trauma scores and lower well-being than women with VB. Unaccompanied mothers with CS perceived visitation restrictions as less appropriate and felt more helpless, angry, worried, and frustrated about the partner's absence than women with VB. CONCLUSIONS: The partner's absence during, but also after childbirth has a major impact on psychological outcomes. Particularly, higher rates of anxiety and PTSS can lead to negative consequences for mothers and their children. Therefore, it is strongly recommended to relax visitation bans and avoid unaccompanied births. Psychological treatment in obstetric units is more urgently needed than ever, especially for women with a caesarean section.

RESUMO

This study aimed to determine the effects of liposomal iron pyrophosphate/ascorbic acid on clinical and psychological outcomes in pregnant women. Women at the 11th-13th weeks of gestation with iron deficiency anaemia assuming Sideremil™ from April 2018 to May 2019 were recruited. Haematochemical, obstetric, neonatal and psychological outcomes were investigated at the enrolment, 21-23 weeks of gestation, 30-32 weeks of gestation and after 6 weeks from childbirth. Results showed significant positive effects on haemoglobin, ferritin, sideremia and transferrin levels, compared to baseline data. A significant improvement of anxiety and depression levels was also observed. Regarding the quality of life, all the domains significantly improved, especially the Physical Role domain. Our results indicate that Sideremil™ may be a valid treatment for iron deficiency anaemia in pregnant women, since it significantly improves haematological and mental health outcomes. However, further studies are needed to confirm these results.

RESUMO

This study aims to understand the factors that can hinder Italian midwifery students' educational process, what messages are given to students during their clinical practice, and how students interact with tutors and other professionals. Seven hundred and eighty Italian students of midwifery were asked to answer an Internet-based questionnaire regarding their own opinions concerning their theoretical-practical formative path. For male Italian students, satisfaction is lower than female students as well as for students from Southern than Northern Italy. Students are dissatisfied with the quality of their academic and practical training, particularly regarding recognising their professional role and their relationship with tutors. Based on these data, it is essential to design a formative path for midwives that considers students' opinions and the positive experiences of other countries.Impact StatementWhat is already known on this subject? Several studies underscore the poor preparation of students for learning in clinical settings. The current reality of the Italian academic path in most universities disregards midwifery students' expectations and formative needs.What do the results of this study add? For male Italian students, satisfaction is lower than for female students and students from Southern than Northern Italy. Students are dissatisfied with the quality of their academic and practical training, particularly regarding recognising their professional role and their relationship with tutors.What are the implications of these findings for clinical practice and/or further research? It is essential to design a formative path for midwives that considers students' opinions and other countries' positive experiences.

RESUMO

This cross-sectional study aimed to evaluate the prevalence of postpartum depression and the associated risk factors in a sample of Italian women at three months after delivery. Eighty women were screened by completing the Edinburgh Postnatal Depression Scale (EPDS). Women with a score ≥10 were evaluated as positive and other variables were detected through the administration of the Postpartum Depression Predictors Inventory.The prevalence of postpartum depression in the sample was 11.25% (EPDS score >10). A statistically significant relationship was found between the predisposition to postnatal depression and various risk factors such as prenatal depression, stressful life experiences marital problems. Furthermore, strong emotional and instrumental support from the partner and a good economic status can represent protective factors. It is essential to promote an integrated approach to postpartum affective disorders in which psychosocial risk factors are taken into account, and adequate screening programs are implemented.Impact StatementWhat is already known on this subject? Pregnancy can cause emotional stress for women with consequent development, in some cases, of mood disorders such as postpartum depression.What do the results of this study add? According to this study, women suffering from postpartum depression showed a significant tendency to anxiety and depression, low perceived support from the partner, and low socio-economic status.What are the implications of these findings for clinical practice and/or further research? It would be desirable to promote an integrated approach to postpartum affective disorders in which psychosocial risk factors are taken into account and adequate screening programs are implemented.

RESUMO

BACKGROUND: Cancer care can negatively impact children's subjective well-being. In this research, well-being refers to patients' self-perception and encompasses their hospital and care delivery assessment. Playful strategies can stimulate treatment compliance and have been used to provide psychosocial support and health education; they can involve gamification, virtual reality, robotics, and healthcare environments. This study aims to identify how playfulness, whenever applicable, can be used as a strategy to improve the subjective well-being of pediatric cancer patients in the Brazilian Unified Health System. METHODS: Sixteen volunteers with experience in pediatric oncology participated in the study. They were physicians, psychologists, child life specialists, and design thinking professionals. They engaged in design thinking workshops to propose playful strategies to improve the well-being of pediatric cancer patients in the Brazilian Unified Health System. Data collection consisted of participatory observations. All activities were video recorded and analyzed through Thematic Analysis. The content generated by the volunteers was classified into two categories: impact of cancer care on children's self-perception and children's perceptions of the hospital and the care delivery. RESULTS: Volunteers developed strategies to help children deal with time at the hospital, hospital structure, and care delivery. Such strategies are not limited to using playfulness as a way of "having fun"; they privilege ludic interfaces, such as toys, to support psychosocial care and health education. They aim to address cancer and develop communication across families and staff in a humanized manner, educate families about the disease, and design children-friendly environments. Volunteers also generated strategies to help children cope with perceptions of death, pain, and their bodies. Such strategies aim to support understanding the meaning of life and death, comprehend pain beyond physicality, help re-signify cancer and children's changing bodies, and give patients active voices during the treatment. CONCLUSIONS: The paper proposes strategies that can improve the well-being of pediatric cancer patients in the Brazilian Unified Health System. Such strategies connect children's experiences as inpatients and outpatients and may inform the implementation of similar projects in other developing countries.

RESUMO

Spinal muscular atrophy (SMA) is a motor neuron disease caused by loss of function mutations in the Survival Motor Neuron 1 (SMN1) gene and reduced expression of the SMN protein, leading to spinal motor neuron death, muscle weakness and atrophy. Although humans harbour the highly homologous SMN2 gene, its defective splicing regulation yields a truncated and unstable SMN protein. The first therapy for SMA was recently approved by the Food and Drug Administration and consists of an antisense oligonucleotide (Nusinersen) rendering SMN2 functional and thus improving patients' motor activity and quality of life. Nevertheless, not all patients equally respond to this therapy and the long-term tolerability and safety of Nusinersen are still unknown. Herein, in vivo splicing assays indicated that the HDAC inhibitor LBH589 is particularly efficient in rescuing the SMN2 splicing defect in SMA fibroblasts and SMA type-I mice-derived neural stem cells. Western blot analyses showed that LBH589 also causes a significant increase in SMN protein expression in SMA cells. Moreover chromatin immunoprecipitation analyses revealed that LBH589 treatment induces widespread H4 acetylation of the entire SMN2 locus and selectively favors the inclusion of the disease-linked exon 7 in SMN2 mature mRNA. The combined treatment of SMA cells with sub-optimal doses of LBH589 and of an antisense oligonucleotide that mimic Nusinersen (ASO_ISSN1) elicits additive effects on SMN2 splicing and SMN protein expression. These findings suggest that HDAC inhibitors can potentiate the activity of Nusinersen and support the notion that 'SMN-plus' combinatorial therapeutic approaches might represent an enhanced opportunity in the scenario of SMA therapy.

RESUMO

OBJECTIVES: The study aimed to determine the influence of religious and moral beliefs on contraceptive use, assisted reproduction and pregnancy termination in Polish women requesting a termination of pregnancy for medical reasons. METHODS: Between 1 June 2014 and 31 May 2016, women deemed eligible for a termination of pregnancy for medical reasons at a Polish tertiary care centre received an anonymous questionnaire comprising 65 items. A total of 150 completed questionnaires were collected. RESULTS: Of the respondents, 95% described themselves as Catholics, including 60% practising Catholics. The study revealed a discrepancy between respondents' beliefs and the teachings of the Catholic Church: an overwhelming majority of respondents used contraception, and 79% were in favour of in vitro fertilisation and believed the treatment should be refunded by the state. Interestingly, 66% of the respondents who attended confession did not perceive abortion as sinful. CONCLUSION: The study detected a considerable discrepancy between declared religiosity and individual interpretations of the commandments and teachings of the Catholic Church. Despite stating they were Catholics, most women did not perceive abortion as sinful and did not follow the teachings of the Catholic Church regarding the sacraments for deceased children.

RESUMO

Outpatient hysteroscopy has become the standard technique for gynaecological exploration of the uterine cavity. The most common reason for failure of the procedure is pain. During the last decade many studies were carried out to improve the equipment as well as the procedural technical aspects. Even so, hysteroscopy is still painful for many patients. Pharmacological pain control has been widely used for hysteroscopy, but these modalities can be invasive, have side effects and are contraindicated in many women. This review examines current literature on non-pharmacological interventions (pressure, stretching, heat, electricity, music and hypnosis) on the pain experienced during outpatient hysteroscopy.

RESUMO

PURPOSE: Gynaecological cancer management in older people represents a current challenge. Therefore, in the present paper, we aimed to gather all the evidence reported in the literature concerning gynecological cancers in the elderly, illustrating the state of art and the future perspectives. METHODS: We searched MEDLINE (PubMed), EMBASE, Cochrane Central Register of Controlled Trials, IBECS, BIOSIS, Web of Science, SCOPUS and Grey literature (Google Scholar; British Library) from January 1952 to May 2017, using the terms "ovarian cancer", "endometrial cancer", "cervical cancer", "gynecological cancers" combined with 'elderly', 'cancer', 'clinical trial' and 'geriatric assessment'. RESULTS: The search identified 81 citations, of which 65 were potentially relevant after initial evaluation and met the criteria for inclusion and were analyzed. We divided all included studies into three different issue: "Endometrial cancer", "Ovarian cancer" and "Cervical cancer". CONCLUSIONS: The present literature review shows that, in spite of the higher burden of comorbidities, elderly patients can also benefit from standard treatment to manage their gynecological cancers. It is important to overcome the common habit of undertreating the elderly patients because they are more fragile and with a lower life expectancy than their younger counterpart. Further trials with elderly women are warranted.

RESUMO

The climacteric is considered a natural phase in a woman's aging process and is defined as the period starting from the decline in ovarian activity until after the end of ovarian function. Genitourinary syndrome of menopause (GSM) is commonly observed in menopausal women and is characterised by a collection of symptoms resulting from changes to the internal and external genitalia as well as the lower urinary tract. Several studies have demonstrated the close association between sexual dysfunction and symptoms related to GSM. Many medications, at different doses, have been studied over the years for the treatment of the symptoms of GSM. More specifically, ultralow-dose intravaginal oestriol and intravaginal dehydroepiandrosterone (DHEA) are reported to improve symptoms, signs, and quality of life of women with GSM, and they are safe owing to their specific local effect. While the dosage and the administration of intravaginal DHEA are well defined, the literature on intravaginal oestriol is less uniform: different doses and times of administration are proposed with different possible combinations with other non-pharmacological therapies, although a more standardised treatment may be necessary. The aim of this review is to summarise the available data about the effects of ultralow-concentration oestriol and intravaginal DHEA on the menopause-related symptoms, quality of life, and sexual function of women affected by GSM.

RESUMO

Overactive bladder syndrome (OAB) is defined by the presence of urinary urgency, with or without urge incontinence, usually accompanied by an increase in urinary frequency and nocturia in the absence of urinary tract infections (UTI) or other diseases. The overall prevalence of OAB symptoms in the female population is reported to be 16.6% and increases with advancing age and menopause. The aetiology of OAB is not fully understood and is likely to affect a heterogeneous population of patients due to changes to their central and peripheral nervous systems. Although OAB is frequently associated with female sexual dysfunction (FSD), its real impact on sexual function in women has been evaluated only in a few studies. The first line of treatment for OAB includes behavioural modification and physical therapy, either as monotherapies or in combination. Many patients who have not had success in managing their symptoms with more conservative therapies may decide to resort to third-line treatments for refractory OAB. These treatments include neuromodulation therapies, particularly transvaginal electrical stimulation (TES) and sacral neuromodulation (SN). The aim of this short commentary is to provide an overview of the effectiveness of these treatments and of their impact on quality of life, body image, sexual function, and emotional well-being.

RESUMO

Although female sexual dysfunctions are common among women with urogynecological conditions, they have not been thoroughly studied and there are still many questions without an answer. The recent evidence on sexual disorders in women with urogynecological diseases shows a quite wide spectrum of therapeutic approaches, which require the physicians to take into account not only the primary symptoms, but also all the associated factors negatively affected. It has been widely underlined that gynecological diseases are often associated with high stress and have a negative impact on quality of life and psychological well-being of women affected. For this reason, a multidisciplinary approach for the management of these diseases is highly recommended. Also in the case of urogynecological disorders, it is important to take into account psychological outcomes throughout the diagnostic and therapeutic process. In the light of these considerations, the aim of this short review is to evaluate the impact of the main urogynecological diseases and the currently available therapeutic options in order to improve quality of life and sexuality of these patients and to stress the need for a multidisciplinary approach in order to minimize the negative consequences of these diseases for the sexual well-being of women and their partners.

RESUMO

BACKGROUND: The purpose of this study is to present the results of a systematic review of published research that focuses on psychological aspects of malignant mesothelioma patients and asbestos-exposed people. METHODS: Our research includes primary studies published between 1980 and 2016, using information from the Cochrane Library, the Psychology Behavioral Sciences Collection, PsychINFO, PubMed, PubGet, PubPsych, and Scopus, in compliance with PRISMA guidelines. RESULTS: We identified 12 papers that investigated the psychological distress and care needs of mesothelioma patients, and nine papers for asbestos-exposed subjects. CONCLUSIONS: This paper highlights the paucity of studies on the psychological distress and care needs of mesothelioma patients and asbestos-exposed subjects. It confirms that malignant mesothelioma is associated with the physical, emotional, and social functioning of patients, while also suggesting that the risk of developing asbestos-related diseases among asbestos-exposed subjects is associated with high levels of psychological distress, despair, and mental health difficulties.

RESUMO

PURPOSE: Despite the numerous studies on the factors involved in the genesis and growth of uterine leiomyomas, the pathogenesis of these tumors remains unknown. Intrinsic abnormalities of the myometrium, abnormal myometrial receptors for estrogen, and hormonal changes or altered responses to ischemic damage during the menstrual period may be responsible for the initiation of (epi)genetic changes found in these tumors. Considering these elements, we aimed to offer an overview about epigenetic and genetic landscape of uterine leiomyomas. METHODS: Narrative overview, synthesizing the findings of literature retrieved from searches of computerized databases. RESULTS: Several studies showed that leiomyomas have a monoclonal origin. Accumulating evidence converges on the risk factors and mechanisms of tumorigenesis: the translocation t (12;14) and deletion of 7q were found in the highest percentages of recurrence; dysregulation of the HMGA2 gene has been mapped within the critical 12q14-q15 locus. Estrogen and progesterone are recognized as promoters of tumor growth, and the potential role of environmental estrogens has been poorly explored. The growth factors with mitogenic activity, such as transforming growth factor-ß3, fibroblast growth factor, epidermal growth factor, and insulin-like growth factor-I are elevated in fibroids and may have a role as effectors of the tumor promotion. CONCLUSION: The new clues on genetics and epigenetics, as well as about the growth factors that control normal and pathological myometrial cellular biology may be of great help for the development of new effective and less invasive therapeutic strategies in the near future.

RESUMO

PURPOSE: Interstitial cystitis/painful bladder syndrome (IC/PBS) is a chronic pain syndrome and a chronic inflammatory condition prevalent in women that leads to urgency, sleep disruption, nocturia and pain in the pelvic area, to the detriment of the sufferer's quality of life. The aim of this review is to highlight the newest diagnostic strategies and potential therapeutic techniques. METHODS: A comprehensive literature review was performed on MEDLINE, PubMed, and Cochrane databases gathering all literature about "Interstitial cystitis" and "Painful Bladder Syndrome". Visual analogue scales, epidemiological strategies, pain questionnaires and similar techniques were not included in this literature survey. RESULTS: The etiology, exact diagnosis and epidemiology of IC/PBS are still not clearly understood. To date, its prevalence is estimated to be in the range of 45 per 100,000 women and 8 per 100,000 men, whereas joint prevalence in both sexes is 10.6 cases per 100,000. There are no "gold standards" in the diagnosis or detection of IC/PBS, therefore, several etiological theories were investigated, such as permeability, glycosaminoglycans, mast cell, infection and neuroendocrine theory to find new diagnostic strategies and potential biomarkers. CONCLUSION: Due to the fact that this disease is of an intricate nature, and that many of its symptoms overlap with other concomitant diseases, it could be suggested to classify the patients with emphasis on the phenotype, as well as their symptom clusters, to tailor the diagnostic and management choices according to the observed biomarkers.

RESUMO

Carcinosarcomas (CS) in gynecology are very infrequent and represent only 2-5% of uterine cancers. Despite surgical cytoreduction and subsequent chemotherapy being the primary treatment for uterine CS, the overall five-year survival rate is 30 ± 9% and recurrence is extremely common (50-80%). Due to the poor prognosis of CS, new strategies have been developed in the last few decades, targeting known dysfunctional molecular pathways for immunotherapy. In this paper, we aimed to gather the available evidence on the latest therapies for the treatment of CS. We performed a systematic review using the terms "uterine carcinosarcoma", "uterine Malignant Mixed Müllerian Tumors", "target therapies", "angiogenesis therapy", "cancer stem cell therapy", "prognostic biomarker", and "novel antibody-drug". Based on our results, the differential expression and accessibility of epithelial cell adhesion molecule-1 on metastatic/chemotherapy-resistant CS cells in comparison to normal tissues and Human Epidermal Growth Factor Receptor 2 (HER2) open up new possibilities in the field of target therapy. Nevertheless, future investigations are needed to clarify the impact of these new therapies on survival rate and medium-/long-term outcomes.

RESUMO

Spinal Muscular Atrophy (SMA) is a neuromuscular disease caused by mutations in the Survival Motor Neuron 1 gene, resulting in very low levels of functional Survival of Motor Neuron (SMN) protein. SMA human induced Pluripotent Stem Cells (hiPSCs) represent a useful and valid model for the study of the disorder, as they provide in vitro the target cells. MicroRNAs (miRNAs) are often reported as playing a key role in regulating neuronal differentiation and fate specification. In this study SMA hiPSCs have been differentiated towards early motor neurons and their molecular and immunocytochemical profile were compared to those of wild type cells. Cell cycle proliferation was also evaluated by fluorescence-activated cell sorting (FACS). SMA hiPSCs showed an increased proliferation rate and also higher levels of stem cell markers. Moreover; when differentiated towards early motor neurons they expressed lower levels of NCAM and MN specific markers. The expression of miR-335-5p; already identified to control self-renewal or differentiation of mouse embryonic stem cells (mESCs); resulted to be reduced during the early steps of differentiation of SMA hiPSCs compared to wild type cells. These results suggest that we should speculate a role of this miRNA both in stemness characteristic and in differentiation efficiency of these cells.

RESUMO

A new biaryl monophosphine ligand (AlPhos, L1) allows for the room-temperature Pd-catalyzed fluorination of a variety of activated (hetero)aryl triflates. Furthermore, aryl triflates and bromides that are prone to give mixtures of regioisomeric aryl fluorides with Pd-catalysis can now be converted to the desired aryl fluorides with high regioselectivity. Analysis of the solid-state structures of several Pd(II) complexes, as well as density functional theory (DFT) calculations, shed light on the origin of the enhanced reactivity observed with L1.
