RESUMO

It was proposed that a reorganization of the relationships between cognitive functions occurs in dementia, a vision that surpasses the idea of a mere decline of specific domains. The complexity of cognitive structure, as assessed by neuropsychological tests, can be captured by exploratory graph analysis (EGA). EGA was applied to the neuropsychological assessment of people (humans) with subjective cognitive decline (SCD), mild cognitive impairment (MCI), and Alzheimer's disease (AD; total N = 638). Both sexes were included. In AD, memory scores detach from the other cognitive functions, and memory subdomains reduce their reciprocal relation. SCD showed a pattern of segregated neuropsychological domains, and MCI showed a noisy and less stable pattern. Results suggest that AD drives a reorganization of cognitive functions toward a less-fractionated architecture compared with preclinical conditions. Cognitive functions show a reorganization that goes beyond the performance decline. Results also have clinical implications in test interpretations and usage.

RESUMO

The experience of empathy for pain is underpinned by sensorimotor and affective dimensions which, although interconnected, are at least in part behaviorally and neurally distinct. Spinal cord injuries (SCI) induce a massive, below-lesion level, sensorimotor body-brain disconnection. This condition may make it possible to test whether sensorimotor deprivation alters specific dimensions of empathic reactivity to observed pain. To explore this issue, we asked SCI people with paraplegia and healthy controls to observe videos of painful or neutral stimuli administered to a hand (intact) or a foot (deafferented). The stimuli were displayed by means of a virtual reality set-up and seen from a first person (1PP) or third person (3PP) visual perspective. A number of measures were recorded ranging from explicit behaviors like explicit verbal reports on the videos, to implicit measures of muscular activity (like EMG from the corrugator and zygomatic muscles that may represent a proxy of sensorimotor empathy) and of autonomic reactivity (like the electrodermal response and Respiratory Sinus Arrhythmia that may represent a general proxy of affective empathy). While no across group differences in explicit verbal reports about the pain stimuli were found, SCI people exhibited reduced facial muscle reactivity to the stimuli applied to the foot (but not the hand) seen from the 1PP. Tellingly, the corrugator activity correlated with SCI participants' neuropathic pain. There were no across group differences in autonomic reactivity suggesting that SCI lesions may affect sensorimotor dimensions connected to empathy for pain.

RESUMO

INTRODUCTION: Hepatocellular carcinoma (HCC) is the most frequent primary malignant liver tumor and typically develops in the context of chronic liver disease, such as liver cirrhosis or chronic hepatitis B virus infection. Ultrasound evaluation, CT scan, and MRI are used to detect HCC. α-fetoprotein (AFP) is a common marker used to detect HCC in the non-pregnant population, which notoriously increases in pregnant women in relation to gestational age. Treatment is driven by the extent of the disease and the severity of underlying liver disease. Pregnancy may represent an obstacle to diagnosis and appropriate treatment of HCC. The aim of this descriptive systematic review was to describe the clinical features and maternal and neonatal outcomes of HCC in pregnancy. MATERIAL AND METHODS: We performed a systematic review of the literature about HCC diagnosed in pregnancy and the postpartum period, with signs or symptoms arising in pregnancy. We included case reports and case series describing the clinical features of women diagnosed with HCC, fibrolamellar variant of HCC, and mixed HCC and cholangiocarcinoma during pregnancy or the postpartum period (with onset of symptoms during pregnancy), from inception to March 2023. The study protocol was registered with the PROSPERO database (Registration number: ID CRD42021275584). RESULTS: We identified 180 records. The articles included in this systematic review were 47 case reports and 5 case series, for a total of 63 pregnancies. The two most frequent predisposing conditions were hepatitis B virus infection (30/63; 47%) and liver cirrhosis (14/63; 22%). Ultrasound evaluation was the most used technique to detect HCC. AFP was higher than normal in 28/46 patients tested (61%). Surgical treatment was the most used therapy, both during pregnancy and after delivery. Twenty-six patients (26/63; 42%) died within 6 months of diagnosis. Survival >24 months was 9% (4/46) in symptomatic and 29% (5/17) in asymptomatic women. No patient with cirrhotic liver survived more than 12 months. Thirty-eight newborns were alive at 28 days of age (38/63; 61%). CONCLUSIONS: Hepatocellular carcinoma in pregnancy is associated with a high risk of maternal and neonatal mortality. Diagnosis in asymptomatic high-risk women or following abnormal maternal serum AFP screening is associated with better maternal outcomes.

RESUMO

OBJECTIVES: Enhanced recovery after surgery (ERAS) protocols provide well-known benefits in the immediate recovery with a shorter length of stay (LOS) also in gynecological surgery. However, the impact of ERAS has not been clearly showed yet regarding long-term consequences and health-related quality of life (HRQL). The aim of this study is to investigate the impact of ERAS on HRQL after hysterectomy for endometrial cancer. DESIGN: Observational retrospective study with propensity score matching (PSM). Participants We administered the SF-36 validated questionnaire to women underwent hysterectomy and lymph nodal staging before and after introducing ERAS protocol, getting, respectively, a standard practice (SP) and ERAS group Settings Academic hospital Methods We collected demographic, clinical, surgical and postoperative data and performed a PSM of the baseline coufouders. We administered the questionnaire four weeks after the surgery. The SF-36 measures HRQL using eight scales: physical functioning (PF), role physical (RLP), bodily pain (BP), general health (GH), vitality (Vt), social functioning (SF), role emotional (RLE) and mental health (MH). Results After PSM, we enrolled a total of 154 patients, 77 in each group (SP and ERA). The two groups were similar in terms of age, BMI, anaesthesiologic risk, Charlson comorbidity index (CCI) and surgical technique (minimally invasive versus open access). Median LOS was shorter for ERAS group (5 versus 3 days; p = 0.02), while no significant differences were registered in the rates of postoperative complications (16.9% versus 17.4%; p = 0.66). Response rates to SF-36 questionnaire were 89% and 92%, respectively, in SP and ERAS group. At multivariate analyzes, the mean scores of SF-36 questionnaire, registered at 28 days weeks after surgery (range 26-32 days), were significantly higher in ERAS group for PF (73.3 vs 91.6; p < 0.00), RLP (median 58.3 vs 81.2; p = 0.02) and SF (37.5 versus 58.3; p = 0.01) domains, when compared to SP patients. Limitations Further follow-up was not possible due to the anonymized data derived from clinical audit. Conclusions ERAS significantly increases HRQL of women underwent surgery for endometrial cancer. HRQL assessment should be routinary implemented in the ERAS protocol.

RESUMO

PURPOSE: The aim of this narrative review is to offer an overview about the role of progesterone levels on pregnancy outcome in patients undergoing assisted reproductive technologies (ARTs). METHODS: A detailed computerized search of the literature was performed in the main electronic databases (MEDLINE, EMBASE, Web of Science) to determine the importance of elevated progesterone levels at different stages of the cycle for pregnancy rates in the in vitro fertilization (IVF) cycle. Our review also provides information on the differences between elevated progesterone levels and their interpretation in normal and in poorly responding women. RESULTS: After careful evaluation, our search strategy yielded a total of 15 included articles, showing the possible factors that may have had an impact on the increased progesterone level before human chorionic gonadotropin (HCG) injection and the different thresholds above which the pregnancy rate was lower. Furthermore, increased progesterone on cycle day 2 or 3 could serve as a marker for increased progesterone in the late follicular phase, which is associated with a lower pregnancy rate. CONCLUSION: Despite the literature data that support the negative effect of elevated progesterone on fresh cycles, due to lack of randomized controlled trials, the value of measuring progesterone in daily practice is questionable. Available evidence supports the detrimental effect of elevated progesterone in different subgroups of women, although there is still the need for defining different thresholds and durations of high progesterone exposure. The need for various thresholds for different cohorts of women, the inter-assay variability is making this decision harder.

RESUMO

Preeclampsia (PE) is characterised by the new onset of hypertension after the 20th week of pregnancy, with or without proteinuria or hypertension that leads to end-organ dysfunction. Since the only definitive treatment is delivery, PE still represents one of the leading causes of preterm birth and perinatal mobility and mortality. Therefore, any strategies that aim to reduce adverse outcomes are based on early primary prevention, prenatal surveillance and prophylactic interventions. In the last decade, intense research has been focussed on the study of predictive models in order to identify women at higher risk accurately. To date, the most effective screening model is based on the combination of anamnestic, demographic, biophysical and maternal biochemical factors. In this review, we provide a detailed discussion about the current and future perspectives in the field of PE. We will examine pathogenesis, risk factors and clinical features. Moreover, recent developments in screening and prevention strategies, novel therapies and healthcare management strategies will be discussed.

RESUMO

INTRODUCTION: In this study, we reviewed the cases of uterine rupture in our setting, identified which of them had previously undergone hysteroscopic septum resection (HSR), and evaluated the main clinical characteristics for each case. MATERIAL AND METHODS: We retrospectively analyzed (ClinicalTrial ID: NCT04449640) the delivery outcomes from the National Perinatal Information System of the National Institute of Public Health of the Republic of Slovenia of the last 20 years (1 January 1999 - 31 December 2019) and cross-linked the patients with surgical data from our electronic database. We collected baseline characteristics, surgical details and obstetrical outcomes. We excluded women who had undergone previous myomectomy or cesarean section (CS) and described the clinical course of each case since no statistical analysis was performed. RESULTS: We found four patients who had uterine rupture in pregnancy after HSR. Median time to pregnancy was 17 months (range 1-60), all the women underwent CS and fetal-maternal outcomes were acceptable in half of the cases. Symptoms were nonspecific and included pain, fetal distress and vaginal bleeding. CONCLUSION: Uterine rupture in pregnancy after a previous HSR is a very rare, but life-threatening event. Prompt diagnosis can ensure successful management and avoid adverse maternal-fetal outcomes.

RESUMO

OBJECTIVE: To compare the diagnostic power of CT scan to a combination of exploratory laparoscopy (EXL) and CT scan in patients with stage IIIC-IV Ovarian Cancer (OC) by anatomic areas. To investigate if adding EXL to CT can reduce unnecessary laparotomy. METHODS: In the period 2009-2017, 350 consecutive patients with FIGO Stage IIIC-IV OC underwent CT and EXL prior to Visceral-Peritoneal debulking (VPD) and were included in the study. Radiologist and surgeons filled an ad-hoc form to report CT scan and EXL of eleven key anatomic areas. The decision to proceed to EXL was based on the CT scan and the decision to proceed to laparotomy (LPT) on CT and EXL. Setting LPT findings as the gold standard, positive and negative predictive value (PPV/NPV), sensitivity, specificity, and accuracy of CT, EXL and CT + EXL were calculated. We broke down the diagnostic outcomes by anatomic areas and determined the rate of unnecessary laparotomy avoided with the findings of EXL. RESULTS: Median time for the EXL was 14 min (SD +/- 3). No complication related to EXL occurred. At EXL, 325 out of 350 patients (93%) proceeded to LPT and 25 patients (7.1%) did not because of exclusion criteria. In 307 patients out of 325 (94.4%) EXL was followed by VPD. Eighteen patients had exclusion criteria found at LPT and had no VPD. EXL reduced the rate of unnecessary/futile laparotomy from 12.2% to 5.1%. CT + EXL showed a significantly higher sensitivity for all anatomic areas except for the lymph nodes. Specificity was not significantly improved. PPV was significantly improved for small bowel, porta hepatis and stomach. NPV displayed a statistical improvement in all anatomic areas except lymph nodes, stomach, and liver. CONCLUSION: The combination CT + EXL has a higher diagnostic power than CT alone, particularly on diaphragm, small bowel serosa and mesentery. The rate of unnecessary laparotomy decreased by almost 60%.

RESUMO

The disabling effects of traumatic brain injuries (TBI) present a significant healthcare concern to developed countries. In order to achieve a reliable prognosis, validated assessment scales are used to monitor the cognitive outcome, like the Level of Cognitive Functioning Scale, or the overall functional outcome, namely the Functional Independence Measure and Glasgow Outcome Scale. The aim of our study was to evaluate the role of Level of Cognitive Functioning Scale (LCF) as an outcome prognostic index in patients with TBI. MATERIALS AND METHODS: Fifty-four patients with TBI with a mean age of 44.9 years (SD 20.915) were enrolled in this retrospective study. Patients were evaluated at admission and at discharge using the Glasgow Outcome Scale, Functional Independence Measure, and Level of Cognitive Functioning Scale. The Glasgow Outcome Scale was also implemented at 6 months after discharge (OUTCOME.GOS), whereas the LCF was used twice a week throughout hospitalization. For our purpose, we named LCF at admission LCFa, whereas permanence in the same LCF value (number of days), LCFaL. RESULTS: Δ.GOS, Δ.FIM (Δ = difference between value at discharge and at admission), and OUTCOME.GOS were significantly affected by age, length of stay, LCFa, and LCFaL. CONCLUSION: The LCF can give a valuable indication to the prognosis of patients with TBI besides monitoring changes in cognitive function. This allows for individual rehabilitation plan, and long-term management strategies could be developed more quickly upon patient's discharge. Consequently, valuable healthcare and social care resources could be assigned correctly.

RESUMO

PURPOSE: Uterine torsion (UT) in pregnancy is a rare condition in obstetric practice. It is defined as a rotation of the uterus of more than 45° around its long axis. Presentations are varied and, most of the time, this condition is recognized at laparotomy or cesarean section (CS). The aim of this study is to summarize the latest evidence about UT in pregnancy. METHODS: A systematic research of the literature was conducted fetching all papers published from March 2006 to June 2020. We collected data regarding clinical features, treatment, and feto-maternal outcomes. Finally, we reported data of a case of UT associated with intrauterine growth restriction (IUGR) diagnosed and treated at our institution. RESULTS: According to our search strategy, 38 articles were included. In 66% of the cases, acute symptomatology was present at the onset, most frequently abdominal pain was reported. In one-third of the cases, UT was diagnosed during CS without clinical suspicion. Only in two cases, including our case, IUGR was reported. Most (66%) of the cases presented a 180° torsion. In the majority of the cases, a CS was performed also with a deliberate or accidental posterior hysterotomy. One and six cases of maternal and fetal death were, respectively, reported. CONCLUSION: UT is an infrequent obstetric condition but should be considered in case of abdominal pain, vomiting, or shock presentation during pregnancy. It could lead to a reduction in uterine blood flow contributing to poor placental perfusion, even though more evidence is needed to clarify this link.

RESUMO

AIM: The scar of cesarean section (CS) is the most common site of abdominal wall endometriosis (AWE), whose tumor degeneration has been reported in an increasing number of cases; the most frequent histological type is clear cell carcinoma (CCC). METHODS: We conducted a systematic research of the literature, collecting data regarding the evidence on tumor degeneration from AWE after CS. Moreover, we reported a case of clear cell borderline tumor (CCBT) originating from AWE. RESULTS: We included data of 37 patients with diagnosis of CCC. The average time between the last CS and the diagnosis of CCC was around 15 years. Overall, 26.0% and 73.9% patients received exclusive local abdominal resection of the lesion and additional surgery, respectively. Lymph nodes involvement was detected in 26.0 % patients and adjuvant chemotherapy was administered in 52.0 % cases. During follow-up period, 15.2% patients died of disease, 32.6% had no evidence of disease, and 17.4% recurred. We diagnosed a CCBT arose in a patients with AWE and a personal history of several surgical procedures for endometriosis, a CS and a subsequent transverse laparotomy. We performed an open bilateral ovariectomy and a large excision of the endometriotic abdominal lesion. CONCLUSION: Tumor degeneration from AWE seems to be a real occurrence with an increasing number of events. Considering the lack of risk factors and diagnostic instruments for tumor degeneration, the removal of AWE localization could be advisable, even though there was long average time between the trigger surgery and the tumor finding.

RESUMO

The human microbiome plays a crucial role in determining the health status of every human being, and the microbiome of the genital tract can affect the fertility potential before and during assisted reproductive treatments (ARTs). This review aims to identify and appraise studies investigating the correlation of genital microbiome to infertility. Publications up to February 2021 were identified by searching the electronic databases PubMed/MEDLINE, Scopus and Embase and bibliographies. Only full-text original research articles written in English were considered eligible for analysis, whereas reviews, editorials, opinions or letters, case studies, conference papers, and abstracts were excluded. Twenty-six articles were identified. The oldest studies adopted the exclusive culture-based technique, while in recent years PCR and RNA sequencing based on 16S rRNA were the most used technique. Regardless of the anatomical site under investigation, the Lactobacillus-dominated flora seems to play a pivotal role in determining fertility, and in particular Lactobacillus crispatus showed a central role. Nonetheless, the presence of pathogens in the genital tract, such as Chlamydia trachomatis, Gardnerella vaginalis, Ureaplasma species, and Gram-negative stains microorganism, affected fertility also in case of asymptomatic bacterial vaginosis (BV). We failed to identify descriptive or comparative studies regarding tubal microbiome. The microbiome of the genital tract plays a pivotal role in fertility, also in case of ARTs. The standardization of the sampling methods and investigations approaches is warranted to stratify the fertility potential and its subsequent treatment. Prospective tubal microbiome studies are warranted.

RESUMO

The aim of this work was to investigate the effect of meteorological conditions on resveratrol concentration of red wines produced in Piacenza viticultural region (Italy). In this regard, six representative estates producing Colli Piacentini Gutturnio DOC (a blend of V. vinifera L. cvs. Barbera and Croatina) vintage wines were analysed for trans- and cis-resveratrol over an 8-year period (1998-2005). Grapes were taken from the same vineyard in each estate by using the same enological practices over the entire investigated period. The meteorological conditions corresponding to the production areas were recorded, and bioclimatic indices were calculated as well. Overall, cis-resveratrol concentration was negatively correlated to Huglin index and August mean temperature, whilst positive correlation coefficients were found when considering the Selianinov index and the rainfall of September.

RESUMO

Copper complexes have shown great versatility and a wide application range across the natural and life sciences, with a particular promise as organic light-emitting diodes. In this work, four novel heteroleptic Cu(I) complexes were designed in order to allow their integration in advanced materials such as metallopolymers. We herein present the synthesis and the electrochemical and photophysical characterisation of these Cu(I) complexes, in combination with ab initio calculations. The complexes present a bright cyan emission (λem ~ 505 nm) in their solid state, both as powder and as blends in a polymer matrix. The successful synthesis of metallopolymers embedding two of the novel complexes is shown. These copolymers were also found to be luminescent and their photophysical properties were compared to those of their polymer blends. The chemical nature of the polymer backbone contributes significantly to the photoluminescence quantum yield, paving a route for the strategic design of novel luminescent Cu(I)-based polymeric materials.

RESUMO

Background and objectives: Cervical leiomyomas are a rare benign disease. Although they are mainly treated surgically, currently, there is not a standardized treatment for cervical leiomyomas. This study aims to summarize current literature evidence about treatment options for cervical leiomyomas. Materials and methods: A systematic research of the literature was conducted in Scopus, PubMed/MEDLINE, ScienceDirect, and the Cochrane Library, including observational prospective and retrospective studies, case series and case reports. We collected data regarding studies related to treatment options for cervical leiomyomas, evaluating the following aspects: study design, population, treatment type, rate of surgical complications, and fertility outcome. Results: According to literature research, 38 articles were included. Among 214 patients, the weighted average age was 39.4 years-old; 23 patients were pregnant. Most of the leiomyomas (78%) were extracervical; in 22% of cases (29 patients) were intracervical; 188 patients (88%) received surgical treatment, 6 (3%) received exclusive conservative management and 21 (10%) underwent interventional radiology treatment. One hundred twenty-seven patients (67.5%) underwent myomectomy, while 54 (28.7%) and 7 (3.7%) hysterectomy and trachelectomy, respectively. Cervical myomectomy was performed by open surgery in 21 out of 127 cases (16.5%), while in 92 (72.4%) and 6 (4.7%) patients the surgical approach was performed by traditional and robot-assisted laparoscopy, respectively. The total rate of surgical complications was 5.6%. Conclusion: Surgery is the primary therapeutic option for cervical leiomyomas with a low rate of surgical complications. Interventional radiology techniques have reported promising but still limited results.

RESUMO

Endometrial carcinoma (EC) is the most common gynecological malignancy in the world. It is mostly detected in postmenopausal women, but it can also occur in women of fertile age who need fertility-sparing therapy. An early diagnosis is the main objective for the correct management of these patients, making it possible to use a fertility-sparing treatment approach without exposing the patients to the risk of cancer progression. In this review, we discuss the role of sonography and hysteroscopy in the detection of intrauterine neoplasm in women of childbearing age.

RESUMO

Urogenital aging is a common process affecting all women in the post-menopausal period of their life, and it is substantially due to oestrogen deprivation after ovarian function cessation. These changes can lead to a progressive, chronic, and complex association of symptoms identified as the genitourinary syndrome of menopause, which has a significant impact on quality of life. Genitourinary syndrome and urogenital aging do not resolve spontaneously and usually recur when treatment is stopped. Therefore, appropriate long-term management is of paramount importance, and local oestrogen is the most effective treatment to reverse urogenital aging and to improve symptoms of genitourinary syndrome as replacement therapy. In some women, topical oestrogen may be inconvenient, it may not achieve complete response, or it may be contra-indicated. Several non-hormonal therapies have been investigated, but few treatments have been reported as potentially able to reverse the urogenital aging process similarly to exogenous oestrogens. Laser seems the most promising, although further studies to define its safety and efficacy are mandatory. Vitamin D and E, and phytotherapy have returned conflicting results and require further confirmation. Lifestyle modifications, physiotherapy, and electrical stimulation represent inexpensive and applicable treatments that might slow urogenital aging. Among the hormonal non-oestrogenic therapies, the use of vaginal oxytocin and dehydroepiandrosterone have been found to be effective compared to placebo, as well as the use of oral ospemifene, which partially relieves vulvovaginal atrophy.

RESUMO

BACKGROUND: The enhanced recovery after surgery concept, which was introduced 20 years ago, is based on a multimodal approach to improve the functional rehabilitation of patients after surgery. OBJECTIVE: This study aimed to validate an enhanced recovery after surgery protocol in gynecologic surgery for both benign and malignant diseases (endometrial cancer and advanced ovarian cancer) and to measure the adherence to the enhanced recovery after surgery protocol items in a randomized trial setting. STUDY DESIGN: In this trial (NCT03347409), we randomly assigned patients to undergo standard perioperative care or enhanced recovery after surgery protocol. The primary outcome is a shorter length of stay in favor of the enhanced recovery after surgery protocol. Secondary outcomes include measurement of adherence to the enhanced recovery after surgery protocol items: comparison of postoperative pain, vomiting, and nausea; anesthesiologic and surgical complications up to 30 days after surgery; rate of readmissions; the time to event in hours for bowel movements, flatus, drinking, hunger, eating, and walking; and the quality of recovery using a validated questionnaire (QoR-15). Finally, we explored the length of stay in the prespecified subgroups at randomization, based on the type of surgical access and gynecologic disease. RESULTS: A total of 168 women were available for analysis: 85 women (50.6%) were assigned to the standard perioperative care group, and 83 women (49.4%) were assigned to the enhanced recovery after surgery protocol group. The 2 groups were similar for age, body mass index, comorbidities, anesthesiological risk, smoking habits, surgical access, and complexity of surgical procedures. Seventy-two patients (42.9%) underwent surgery for benign disease, 48 (28.6%) for endometrial cancer, and 48 (28.6%) for ovarian cancer. Women in the enhanced recovery after surgery protocol group had a shorter length of stay (median: 2 [interquartile range, 2-3] vs 4 [interquartile range, 4-7] days; P<.001). A decreased rate of postoperative complications was noted for the enhanced recovery after surgery protocol group, as well as an earlier time to occur for all the events. Mean adherence to protocol items was 84.8% (95% confidence interval, 79.7-89.8), and we registered a better satisfaction in the enhanced recovery after surgery protocol group. The shortening of the length of stay was confirmed also in the prespecified subgroup analysis. CONCLUSION: Application of the enhanced recovery after surgery protocol in gynecologic surgery translated to a shorter length of stay regardless of surgical access and type of gynecologic disease. Adherence to the enhanced recovery after surgery protocol items in the setting of a randomized trial was high.
