RESUMEN

BACKGROUND: Childhood abuse and neglect pose important risk factors for the development of psychopathology during pregnancy. However, only a few studies have assessed the effects of a specific type of abuse during the perinatal period, namely, psychological maltreatment, which includes emotional abuse and neglect. These studies have found that women who have experienced psychological maltreatment exhibit higher levels of antenatal depressive symptoms and greater difficulties forming attachment with their babies than women who have not experienced this kind of adversity. The aim of this study was to examine how emotional abuse and neglect experiences may favor the occurrence of psychological distress in pregnant women, and whether prenatal attachment might explain this association. METHODS: Participants comprised 128 Italian pregnant women ranging in age from 21 to 46 years (Mage = 33.4; SD = 6.10). Women responded to the following self-report instruments: CECA.Q and CTQ-SF, for the assessment of psychological maltreatment experiences; MAAS, for the evaluation of prenatal attachment; and PAMA, for the assessment of perinatal psychological distress. RESULTS: Pearson correlations revealed a positive association between childhood neglect and perinatal psychological distress and a negative association between childhood neglect and prenatal attachment scores. No significant correlations were found for emotional abuse. Perinatal psychological distress was negatively associated with prenatal attachment. Mediation analyses showed significant associations between childhood neglect and the dimensions of perinatal affectivity and prenatal maternal attachment. Prenatal maternal attachment mediated the relationship between neglect and perinatal psychological distress. CONCLUSIONS: The transition to motherhood is a sensitive period, particularly for women who have experienced abuse and neglect during childhood. These experiences may negatively impact a woman's disposition to emotionally and behaviorally engage in the formation of a bond with their unborn baby. These results may have important prevention and clinical implications and thus warrant further exploration.

RESUMEN

To evaluate if a preoperative medical treatment with the GnRH-antagonist relugolix in combination therapy in a series of patients with abnormal uterine bleeding associated with uterine myomas may correct the anemia before scheduled surgery for myoma-associated AUB. Thirty-one patients scheduled for surgery underwent a pre-operative three-month course with a daily oral tablet of 40 mg relugolix, 1 mg estradiol, and 0.5 mg norethindrone acetate. Hemoglobin levels, uterine volumes, largest myoma diameter, and VAS score for dysmenorrhea, pelvic pressure and bleeding discomfort, and indication to surgery were evaluated at study enrollment and at the end of therapy. Mean hemoglobin levels increased by 25%, from 9.3 ± 1.1 to 11.6 ± 1.7 g/dL after three months (p < 0.001). Uterine volume decreased from 380.7 ± 273.4 mL to 281.7 ± 198.7 mL (p < 0.001), whereas the diameter of the largest myoma decreased from 6.4 ± 2.8 cm to 5.5 ± 2.2 cm (p < 0.001). Four patients (13%), initially planned for a laparotomy procedure, were converted to a minimally-access procedure, whereas in eight patients (26%) surgery was avoided after medical therapy. Dysmenorrhea score improved from 4.7 ± 3.2 to 0.6 ± 1.1 (p < 0.0001). Pelvic pressure score decreased from 5.9 ± 2.1 to 3.1 ± 2.3 (p < 0.0001), whereas bleeding discomfort decreased from 7.4 ± 3.0 to 0.4 ± 1.6 (p < 0.0001). Preoperative GnRH-antagonist therapy may enhance hemoglobin levels, decrease uterine and myoma size, and alleviate symptoms, potentially enabling safe surgical procedures.

RESUMEN

Respiratory tract diseases caused by influenza virus and SARS-CoV-2 can represent a serious threat to the health of pregnant women. Immunological remodulation for fetus tolerance and physiological changes in the gestational chamber expose both mother and child to fearful complications and a high risk of hospitalization. Vaccines to protect pregnant women from influenza and COVID-19 are strongly recommended and vaccine co-administration could be advantageous to increase coverage of both vaccines. The attitude to accept both vaccines is affected by several factors: social, cultural, and cognitive-behavioral. In Palermo, Italy, during the 2021-2022 influenza season, a cross-sectional study was conducted to evaluate pregnant women's intention to adhere to co-administration of influenza and COVID-19 vaccines. The determinants of vaccination attitude were investigated through the administration of a questionnaire and the Health Action Process Approach theory was adopted to explore the cognitive behavioral aspects. Overall, 120 pregnant women were enrolled; mean age 32 years, 98.2% (n = 118) of Italian nationality and 25.2% (n = 30) with obstetric or pathological conditions of pregnancy at risk. Factors significantly associated with the attitude to co-administration of influenza and COVID-19 vaccines among pregnant women were: high level of education (OR = 13.96; p < 0.001), positive outcome expectations (OR = 2.84; p < 0.001), and self-efficacy (OR = 3.1; p < 0.001). Effective strategies to promote the co-administration of the influenza vaccine and the COVID-19 vaccine should be based on the communication of the benefits and positive outcomes of vaccine co-administration and on the adequate information of pregnant women.

RESUMEN

PURPOSE: To evaluate the efficacy and long-term safety (up to 108 months) of treatment with Dienogest in patients with endometriosis. METHODS: Patients with chronic pelvic pain endometriosis-related were enrolled in this observational study from June 2012 to July 2021. The patients enrolled took Dienogest 2 mg as a single daily administration. Group B of long-term therapy patients (over 15 months) were compared with group A of short-term therapy patients (0-15 months). The effects of the drug on pain variation were assessed using the VAS scale and endometriomas dimensions through ultrasonographic evaluation. Furthermore, has been valuated the appearance of side effects and the effect of the drug on bone metabolism by performing MOC every 24 months in group B. RESULTS: 157 patients were enrolled. The mean size of the major endometrioma progressively decreased from 33.2 mm (29.4-36.9) at T0 to 7 mm (0-15.8) after 108 months of treatment. We found a significant improvement in dysmenorrhea, dyspareunia, dyschezia and non-cyclic pelvic pain. As for the side effects, both groups complained menstrual alterations present in 22.9%. In 27.6% of group B, osteopenia was found. Group B had a higher percentage statistically significant of side effects such as headaches, weight gain and libido reduction compared to group A. 2 CONCLUSION: Long-term therapy with Dienogest has proven effective in controlling the symptoms of the disease and reducing the size of endometriomas, with an increase in the positive effects related to the duration of the intake and in the absence of serious adverse events. Study approved by the "Palermo 2" Ethics Committee on July 2, 2012 No. 16.

RESUMEN

Human papillomavirus (HPV)-related diseases are still a challenge for public health. Some studies have shown the effects of preventive strategies on them, but studies at the national level are few in number. Therefore, a descriptive study through hospital discharge records (HDRs) was conducted in Italy between 2008 and 2018. Overall, 670,367 hospitalizations due to HPV-related diseases occurred among Italian subjects. In addition, a significant decrease in hospitalization rates for cervical cancer (average annual percentage change (AAPC) = -3.8%, 95% CI = -4.2, -3.5); vulval and vaginal cancer (AAPC = -1.4%, 95% CI = -2.2, -0.6); oropharyngeal cancer; and genital warts (AAPC = -4.0%, 95% CI = -4.5, -3.5) was observed during the study period. Furthermore, strong inverse correlations were found between screening adherence and invasive cervical cancer (r = -0.9, p < 0.001), as well as between HPV vaccination coverage and in situ cervical cancer (r = -0.8, p = 0.005). These results indicate the positive impact of HPV vaccination coverage and cervical cancer screening on hospitalizations due to cervical cancer. Indeed, HPV vaccination also resulted in a positive impact on the decrease in hospitalization rates due to other HPV-related diseases.

RESUMEN

The evaluation of endometriosis in an adolescent girl is a challenging topic. The initial stage of the disease and the limited diagnostic instrument appropriate for the youth age and for its typical features can reduce the ability of the gynecologist. At the same time, missing a prompt diagnosis can delay the beginning of specific and punctual management of endometriosis, which could avoid a postponed diagnosis from 6 to 12 years, typical of adolescent girls complaining of dysmenorrhea. This article aimed to answer all the potential questions around the diagnosis and management of endometriosis in adolescents starting from a clinical case looking at the possible solution that is easily reproducible in the clinical practice.

RESUMEN

PURPOSE: The aims of this observational study were: to assess the relationship between psychological variables, pain, Duration Untreated Endometriosis (DUE) in a sample of women with Endometriosis; and to assess the effect of dienogest 2 mg/daily (DNG) and dienogest/ethinylestradiol 0.03 mg/daily (EE/DNG) on Symptoms, QoL, HRQoL, pain and sexual satisfaction, over time. METHODS: 64 women constituted the study group; (56%) took DNG and (44%) took EE/DNG. VAS, SF-36, EHP-30 and ISS were used to assess endometriosis-associated pelvic pain, QoL, HRQoL and sexual satisfaction, respectively. The study included one follow-up at 18 months. RESULTS: At T0, a longer period of DUE was related both to worst HRQoL and Physical QoL. At T1, a correlation was found between longer DUE and worst HRQoL. At T0, a negative correlation was found between VAS and PCS and between VAS and EHP-30. At T1, the same above correlation was found between VAS and PCS/MCS and VAS and EHP-30 scale. There was a correlation between ISS and VAS. ANOVA showed a reduction in dysmenorrhea, in general pain level and an improvement in emotional wellbeing, relationship with medical profession, and PCS over time, regardless to type of treatment. Moreover, a significant time × treatment group interaction for dysmenorrhea was found. CONCLUSION: DUE and pain are important variables related to psychological aspects of women with endometriosis. Treatment with both DNG and EE/DNG may have positive effects on the QoL, HRQoL and symptoms. Moreover, DNG seems to have a greater effect than EE/DNG on dyspareunia reduction over time.

RESUMEN

Pregnant women are at higher risk of severe Coronavirus disease 2019 (COVID-19) complications than non-pregnant women. The initial exclusion of pregnant women from anti-SARS-CoV-2 vaccines clinical trials has caused a lack of conclusive data about safety and efficacy for this vulnerable population. This cross-sectional study aims to define the factors related to vaccination adherence in a sample of women experiencing high-risk pregnancies. The recruited women completed a questionnaire based on the Health Belief Model. Data were analyzed to evaluate the associations between socio-demographic variables and vaccination acceptance through descriptive, univariate and multivariate logistic analyses. Among the 233 women enrolled, 65.2% (n = 152) declared that they would accept the anti-SARS-CoV-2 vaccine. Multivariate analysis showed that vaccination acceptance was associated with a high educational level (aOR = 4.52, p = 0.001), a low perception of barriers to vaccination (aOR = 1.58, p = 0.005) and the gynecologist's advice (aOR = 3.18, p = 0.01). About a third of pregnant women are still hesitant about the anti-SARS-CoV-2 vaccine, probably because of the conflicting information received from media, friends, acquaintances and health institutions. Determining factors linked to vaccine hesitancy among pregnant women is useful for creating vaccination strategies that increase vaccination uptake.

RESUMEN

PURPOSE: The aim of the study was to assess the length of diagnostic delay of symptomatic endometriosis in Italy and analyse the presence of correlations between the socio-demographic status of patients and the clinical characteristics/type of diagnosis. MATERIALS AND METHODS: This multicenter cross-sectional questionnaire-based study was conducted in 10 tertiary Italian referral centres for diagnosis and treatment endometriosis. A total of 689 respondents with histologically proven endometriosis and onset of the disease with pain symptoms completed an on-line self-reported questionnaire written in their own language (World Endometriosis Research Foundation-Endometriosis Phenome and Biobanking Harmonisation Project-Endometriosis Patient Questionnaire-Minimum) evaluating endometriosis related symptoms, family history of endometriosis and chronic pelvic pain, demographic data, as well as medical, reproductive, and obstetric history. RESULTS: The mean diagnostic delay found was of 11.4 years. The mean time (14.8 years) from symptoms onset to diagnosis was significantly longer among patients aged 9-19 vs patients aged 20-30 (mean 6.9 years, p < 0.001) and patients aged 31-45 (mean 2.9, p < 0.001). No significant association were found between a delayed diagnosis and any of the clinically relevant factors such as the number or severity of the reported symptoms, familiarity, hormonal therapy intake or methodology of diagnosis. CONCLUSIONS: The mean diagnostic delay of endometriosis in Italy is about 11 years. The delay can be up to 4 years longer in patients with pain symptoms onset under 20 years. Educating clinicians and patients on pathologic nature of endometriosis related pelvic pain is advisable to reduce waiting time to diagnosis, especially for young women.

RESUMEN

BACKGROUND: Acute pancreatitis (AP) caused by gallstones has an increased rate of incidence in young women in the 2 years postpartum. Middle-aged women with longer periods of breastfeeding have less hospitalization for gallbladder disease. AIM: To investigate whether breastfeeding or other variables may be associated with AP. METHODS: We conducted a population-based case-control study among all Sicilian women of childbearing age, and we identified all women who delivered (2013-2016) and had AP within 2 years postpartum. We reviewed their medical records, and for each case we matched four women of the same age (± 5 years), without AP. Univariate and multivariate logistic regression was used to estimate the odds ratios (OR) with their confidence intervals (CI) to assess associations between AP and clinical determinants. RESULTS: In the 74 women with AP and 298 controls at univariate analysis, > 6 months oral contraception history (p < 0.01; OR 3.30; 95% CI 1.33-8.16), previous biliary disease (p < 0.001; OR 5.90; 95% CI 1.98-17.57) and smoking (p = 0.035; OR 2.04; 95% CI 1.04-4.0) were predictors of AP; amenorrhea ≥ 3 months (p < 0.001; OR 0.34; 95% CI 0.19-0.59) and breastfeeding ≥ 3 months (p < 0.001; OR 0.07; 95% CI 0.03-0.14) were protective. At multivariate analysis, previous biliary disease (p = 0.011; OR 5.49; 95% CI 1.48-20.38) and breastfeeding ≥ 3 months (p < 0.001; OR 0.06; CI 95% 0.03-0.14) were associated with AP. CONCLUSIONS: Women who breastfeed for at least 3 months and do not have a history of biliary disorders have reduced risk of developing AP in the 2 years after delivery.

RESUMEN

Maternal immunization is considered the best intervention in order to prevent influenza infection of pregnant women and influenza and pertussis infection of newborns. Despite the existing recommendations, vaccination coverage rates in Italy remain very low. Starting from August 2018, maternal immunization against influenza and diphtheria-tetanus-pertussis were strongly recommended by the Italian Ministry of Health. We conducted a cross sectional study to estimate the effectiveness of an educational intervention, conducted during childbirth classes in three general hospitals in the Palermo metropolitan area, Italy, on vaccination adherence during pregnancy. To this end, a questionnaire on knowledge, attitudes, and immunization practices was structured and self-administered to a sample of pregnant women attending childbirth classes. Then, an educational intervention on maternal immunization, followed by a counseling, was conducted by a Public Health medical doctor. After 30 days following the interventions, the adherence to the recommended vaccinations (influenza and pertussis) was evaluated. At the end of the study 326 women were enrolled and 201 responded to the follow-up survey. After the intervention, among the responding pregnant women 47.8% received influenza vaccination (+44.8%), 57.7% diphtheria-tetanus-pertussis vaccination (+50.7%) and 64.2% both the recommended vaccinations (+54.8%). A significant association was found between pregnant women that received at least one vaccination during pregnancy and higher educational level (graduation degree/master's degree), employment status (employed part/full-time) and influenza vaccination adherence during past seasons (at least one during last five years). The implementation of vaccination educational interventions, including counseling by healthcare professionals (HCPs), on maternal immunization during childbirth courses improved considerably the vaccination adherence during pregnancy.

RESUMEN

Neuronal dendritic arborizations and dendritic spines are crucial for a normal synaptic transmission and may be critically involved in the pathophysiology of epilepsy. Alterations in dendritic morphology and spine loss mainly in hippocampal neurons have been reported both in epilepsy animal models and in human brain tissues from patients with epilepsy. However, it is still unclear whether these dendritic abnormalities relate to the cause of epilepsy or are generated by seizure recurrence. We investigated fine neuronal structures at the level of dendritic and spine organization using Golgi impregnation, and analysed synaptic networks with immunohistochemical markers of glutamatergic (vGLUT1) and GABAergic (vGAT) axon terminals in human cerebral cortices derived from epilepsy surgery. Specimens were obtained from 28 patients with different neuropathologically defined aetiologies: type Ia and type II focal cortical dysplasia, cryptogenic (no lesion) and temporal lobe epilepsy with hippocampal sclerosis. Autoptic tissues were used for comparison. Three-dimensional reconstructions of Golgi-impregnated neurons revealed severe dendritic reshaping and spine alteration in the core of the type II focal cortical dysplasia. Dysmorphic neurons showed increased dendritic complexity, reduction of dendritic spines and occasional filopodia-like protrusions emerging from the soma. Surprisingly, the intermingled normal-looking pyramidal neurons also showed severe spine loss and simplified dendritic arborization. No changes were observed outside the dysplasia (perilesional tissue) or in neocortical postsurgical tissue obtained in the other patient groups. Immunoreactivities of vGLUT1 and vGAT showed synaptic reorganization in the core of type II dysplasia characterized by the presence of abnormal perisomatic baskets around dysmorphic neurons, in particular those with filopodia-like protrusions, and changes in vGLUT1/vGAT expression. Ultrastructural data in type II dysplasia highlighted the presence of altered neuropil engulfed by glial processes. Our data indicate that the fine morphological aspect of neurons and dendritic spines are normal in epileptogenic neocortex, with the exception of type II dysplastic lesions. The findings suggest that the mechanisms leading to this severe form of cortical malformation interfere with the normal dendritic arborization and synaptic network organization. The data argue against the concept that long-lasting epilepsy and seizure recurrence per se unavoidably produce a dendritic pathology.

RESUMEN

Coronavirus disease 2019 (COVID-19) is a global public health emergency with many clinical facets, and new knowledge about its pathogenetic mechanisms is deemed necessary; among these, there are certainly coagulation disorders. In the history of medicine, autopsies and tissue sampling have played a fundamental role in order to understand the pathogenesis of emerging diseases, including infectious ones; compared to the past, histopathology can be now expanded by innovative techniques and modern technologies. For the first time in worldwide literature, we provide a detailed postmortem and biopsy report on the marked increase, up to 1 order of magnitude, of naked megakaryocyte nuclei in the bone marrow and lungs from serious COVID-19 patients. Most likely related to high interleukin-6 serum levels stimulating megakaryocytopoiesis, this phenomenon concurs to explain well the pulmonary abnormal immunothrombosis in these critically ill patients, all without molecular or electron microscopy signs of megakaryocyte infection.

RESUMEN

Coronavirus Disease 2019 (COVID-19) is an ongoing public health emergency and new knowledge about its immunopathogenic mechanisms is deemed necessary in the attempt to reduce the death burden, globally. For the first time in worldwide literature, we provide scientific evidence that in COVID-19 vasculitis a life-threatening escalation from type 2 T-helper immune response (humoral immunity) to type 3 hypersensitivity (immune complex disease) takes place. The subsequent deposition of immune complexes inside the vascular walls is supposed to induce a severe inflammatory state and a cytokine release syndrome, whose interleukin-6 is the key myokine, from the smooth muscle cells of blood vessels.

RESUMEN

In difference to other solid malignancies, the identification of biomarkers for the prediction of malignant melanoma (MM) response to immunotherapy is limited. The aim of the current study was to evaluate the immunohistochemical (IHC) expression of MMR proteins in a cohort of MM metastatic patients receiving anti PD-1 treatments. The therapeutic response of patients was also retrospectively assessed. The cohort of the current study included 14 patients with advanced MM that had received anti PD-1 from January 2014 to December 2016 (12 males, 2 females; average age, 71 years; age range, 47-88 years). IHC analysis of MLH1, PMS2, MSH2 and MSH6 proteins was performed on paraffin-embedded primary tumor samples from each patient and on the 23 available metastasis specimens obtained from the Division of Pathology (University of Modena and Reggio Emilia). The results revealed that 7% of the primary melanoma tissue obtained from the patient cohort exhibited the loss of expression of at least one MMR protein. Three samples from one patient, including one primary melanoma and two metastases, exhibited no MSH6 expression and had the most successful response to anti PD-1 treatment, with a progression-free survival and overall survival of 956 and 2,546 days, respectively. In conclusion, the assessment of MMR protein expression represents a potential predictive marker that may have critical importance for patients with primary and metastatic MM, primarily as criterion for the adoption of immunotherapy treatments.

RESUMEN

Rare earth metals (REM) are a group of 17 chemical elements in the periodic table, namely scandium (Sc), yttrium (Y) and the lanthanides. In relation to atomic volume and geological behavior, the lanthanides are further subdivided into light, medium and heavy REM. They find many applications in the technological field; however, their impact on the human health is still conflicting and, for many aspects, unknown. During a research program carried on 113 cases of female breast cancer, immunohistochemically categorized in Her2-positive (29 cases), Her2-negative (57 cases) and triple negative (27 cases), aimed to evaluate the role of environmental particulate in carcinogenesis by elemental microanalysis, for the first time in literature we have detected a REM uptake, in detail europium (Eu), dysprosium (Dy) and praseodymium (Pr), inside the neoplastic cells belonging to a single triple negative breast cancer. Curiously, the woman affected by this form of malignancy had worked in the ceramic industry, a well-known source of REM, during her life, and she was the one and only patient of our series to be dedicated to this activity. The medical repercussions of our findings are here discussed: in fact, a REM detection in only 1 of 113 examined cases seems to exclude active roles in breast carcinogenesis and discloses new possibilities for therapeutic developments in triple negative breast cancer.

RESUMEN

Here, referred for the first time in literature, we present the forensic case of death, with suicidal intent, following ingestion of a conspicuous amount of quaternary ammonium compounds contained in an unguarded bottle of household detergent. The deceased person was a young female patient at a psychiatric facility; the cause of death was acute heart failure due to spotty infiltration of neutrophils, lymphocytes and plasma cells in the myocardial tissue, observable in the course of toxic myocarditis. The dominant pathogenetic factors involved are direct damage of myocardial cells and a superimposed immune response extending to the epicardial perivascular spaces. This rare form of acute myocarditis has never been previously described. Moreover, this fatal event emphasizes the need for planned clinical risk-management measures and for guidelines to prevent future adverse events of this kind in psychiatric facilities.
