Digital mental health interventions for people with epilepsy: a systematic review. Seizure 2023; 107:91-103. [PMID: 37001253 DOI: 10.1016/j.seizure.2023.03.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 03/06/2023] [Accepted: 03/22/2023] [Indexed: 03/30/2023] Open
Abstract
OBJECTIVE Although mental health difficulties are common in people with epilepsy, their assessment and treatment are rarely incorporated into routine medical care, with detrimental effects on quality of life. Several barriers to access traditional face to face interventions have been identified, including travel restriction and shortage of appropriately trained mental health clinicians. Digital mental health interventions offer the potential to improve access to mental health treatment. The main aim of the present study is to systematically review the empirical literature to identify what digital mental health interventions for adults, children and young people with epilepsy are currently available, as well as exploring if these interventions are effective in improving mental health and wellbeing. METHODS Searches were conducted using the MEDLINE, PsycINFO, Web of Science and Embase. The reference lists of papers collected were examined in order to identify any further relevant articles cited in peer-reviewed journals. A total of 1490 papers were identified; of these 11 were included in this review. The protocol was registered in the PROSPERO database (CRD42022318658) and the PRISMA 2020 statement was followed. RESULTS Seven digital interventions were identified. All interventions were based predominantly on CBT and mindfulness techniques and showed promising results in reducing symptoms of depression, with some studies also reporting encouraging results in reducing anxiety and improving satisfaction with life and the quality of life of adults and children and young people with epilepsy. CONCLUSIONS In summary, digital mental health interventions for people with epilepsy seem to be effective and have the potential to improve access to psychological interventions and reach underserved clinical populations. However, further well-powered and methodological rigorous studies are needed to confirm the effect of such interventions for people with epilepsy.

Microplastics distribution and possible ingestion by fish in lacustrine waters (Lake Bracciano, Italy). ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2022; 29:68179-68190. [PMID: 35538341 DOI: 10.1007/s11356-022-20403-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Accepted: 04/19/2022] [Indexed: 06/14/2023]
Abstract
Understanding the spatial distribution patterns of microplastics (plastics < 5 mm) contributes to the assessment of sources and sinks of pollution thus providing information for the management of biota safety and overall ecosystem functionality. We chose a semi-closed study area, Lake Bracciano (Italy), to assess the environmental variability of contamination, focusing on the water compartment and the exposure of biota, specifically fish, by analysing the ingestion of microplastics. The focus of this study is to evaluate the concentration of microplastics in water (surface and column) across the lake and the ingestion of microplastics by two fish species of economic interest: Atherina boyeri and Coregonus lavaretus, inhabiting demersal and pelagic habitats respectively. Results show a surface contamination of 392,000 ± 417,000 items km-2 and a column one of 0.76 ± 1.00 items m-3. Fragments were the most abundant in surface while fibres in the column. Microplastics were found in C. lavaretus specimens, corresponding to contamination frequency of 5% and concentration of 0.15 items/fish. The main polymer found in water was polyethylene (81%); of minor percentages, there were various other polymers, including polystyrene and acrylic, which were also found in fish. As scientific literature provides few research where water and fish are simultaneously sampled, this investigation wants to contribute filling this knowledge gap by investigating for the first time a volcanic lake.

The Role of 2D/3D Ultrasound to Assess the Response to Neoadjuvant Chemotherapy in Locally Advanced Cervical Cancer. Oncology 2020; 98:807-813. [PMID: 32892198 DOI: 10.1159/000505426] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Accepted: 11/22/2019] [Indexed: 12/24/2022]
Abstract
INTRODUCTION Different imaging techniques were introduced to improve preoperative clinical staging of locally advanced cervical cancer (LACC) with transvaginal ultrasound (TV-US) or transrectal ultrasound (TR-US) representing a promising staging technique in the evaluation of the local extension of the disease for invasive tumors. The aim of this study was to evaluate the response to neoadjuvant chemotherapy (NACT) in LACC by 2D/3D ultrasound examination. MATERIALS AND METHODS We prospectively enrolled patients affected by histologically and clinically confirmed LACC. All patients were scheduled for 3 cycles of platinum-based NACT followed by radical surgery. The ultrasound examination was performed at every cycle and within 10 days before surgery. The parameters evaluated were: the volume (automatically computed by the VOCAL software) and the mass vascularization. RESULTS From March 2010 to March 2019, 157 women were recruited. Among these patients, 12 of them were excluded: 6 for the presence of distant metastases, 4 for rare histology, and 2 for severe comorbidities not allowing the protocol treatment. Seventeen patients after NACT were excluded because they were not amenable to radical surgery. Thus, 128 were considered for the final analysis of whom 106 (83%) were considered responders to NACT by histology. The sensibility and specificity of ultrasound with regard to the response to chemotherapy compared to histological specimen were 94 and 82%, respectively, with an accuracy of 92%. The positive predictive value and negative predictive value were 96 and 75%, respectively. Finally, we found that nonetheless there was a trend towards a continuous response to chemotherapy among patients who were considered responders to NACT at pathological examination; the major volume and vascularization index (VI) reduction were observed during the first 2 cycles (74, 71% and 47, 63%, respectively). On the contrary, non-responders showed an initial reduction of the VI (4.86 consisting of 33%, 95% CI 0.79-8.92, p = 0.013), but no significant modification in tumour volume along NACT. CONCLUSION 2D/3D ultrasound is useful in assessing early response to NACT in patients with LACC.

Hepatobiliary Disease Resection in Patients with Advanced Epithelial Ovarian Cancer: Prognostic Role and Optimal Cytoreduction. Ann Surg Oncol 2020; 28:222-230. [PMID: 32779050 PMCID: PMC7752869 DOI: 10.1245/s10434-020-08989-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2019] [Accepted: 05/31/2020] [Indexed: 12/26/2022]
Abstract
Objective The purpose of this study was to evaluate the feasibility and safety in terms of prognostic significance and perioperative morbidity and mortality of cytoreduction in patients affected by advance ovarian cancer and hepato-biliary metastasis. Methods Patients with a least one hepatobiliary metastasis who have undergone surgical treatment with curative intent of were considered for the study. Perioperative complications were evaluated and graded with Accordion severity Classification. Five-year PFS and OS were estimated using the Kaplan–Meier curve. Results Sixty-seven (20.9%) patients had at least one metastasis to the liver, biliary tract, or porta hepatis. Forty-four (65.7%) and 23 (34.3%) patients underwent respectively high and intermediate complexity surgery according. Complete cytoreduction was achieved in 48 (71.6%) patients with hepato-biliary disease. In two patients (2.9%) severe complications related to hepatobiliary surgery were reported. The median PFS for the patients with hepato-biliary involvement (RT = 0 vs. RT > 0) was 19 months [95% confidence interval (CI) 16.2–21.8] and 8 months (95% CI 6.1–9.9). The median OS for the patients with hepato-biliary involvement (RT = 0 vs. RT > 0) 45 months (95% CI 21.2–68.8 months) and 23 months (95% CI 13.9–32.03). Conclusions Hepatobiliary involvement is often associated with high tumor load and could require high complex multivisceral surgery. In selected patients complete cytoreduction could offer survival benefits. Morbidity related to hepatobiliary procedures is acceptable. Careful evaluation of patients and multidisciplinary approach in referral centers is mandatory.

Evaluation of Parametrial Status in Locally Advanced Cervical Cancer Patients after Neoadjuvant Chemotherapy: A Prospective Study on Diagnostic Accuracy of Three-Dimensional Transvaginal Ultrasound. Oncology 2020; 98:603-611. [PMID: 32492692 DOI: 10.1159/000506642] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2020] [Accepted: 02/10/2020] [Indexed: 11/19/2022]
Abstract
OBJECTIVES To analyze the diagnostic accuracy of two-dimensional (2D) and three-dimensional transvaginal ultrasound (3D TV-US) for evaluation of parametrial status in locally advanced cervical cancer patients after neoadjuvant chemotherapy (NACT), using histology as the gold standard. METHODS Consecutive patients with histologically confirmed cervical cancer were staged according to FIGO (International Federation of Gynaecology and Obstetrics) criteria. All IB2-IIIB FIGO stage patients were examined by 2D and 3D TV-US and magnetic resonance imaging (MRI) at the diagnosis time (T0) and after NACT. At T0, the US evaluation of parametrial involvement was compared to MRI before treatment. The results of US and MRI examinations of parametrial status after NACT were compared with the histological specimen. RESULTS We enroled 51 consecutive patients in the study. Before chemotherapy, clinical examination under anaesthesia identified parametrial involvement in 48 patients, ultrasonography in 46 patients, and MRI in 49 patients. The agreement between US and MRI was 94%. The sensitivity of US for parametrial status was 93.8%, with a positive predictive value of 97.8%, using MRI as the standard. The correlation between US and MRI was statistically significant (p = 0). After chemotherapy, histological examination of surgical specimens identified parametrial involvement in 3 patients. Ultrasonography correctly identified those cases with parametrial infiltration, recording a sensitivity of 100%, specificity of 90.9%, positive predictive value of 50%, and negative predictive value of 100%. The MRI had a sensitivity of 100%, specificity of 45.5%, positive predictive value of 14.3%, and negative predictive value of 100%, respectively. The concordance in the identification of the presence/absence of infiltration between US and MRI with histology was 90% (p = 0.001) and 61%, respectively, after chemotherapy treatment. Particularly, in defining the degree of infiltration, the agreement between US and MRI with histology was 90 and 58%, respectively. CONCLUSION In locally advanced cervical cancer patients, 2D/3D TV-US can be considered accurate in the evaluation of parametrial infiltration to assess the response to NACT. It could be included as a diagnostic method in the preoperative work-up of cervical cancer.

Plastic abundance and seasonal variation on the shorelines of three volcanic lakes in Central Italy: can amphipods help detect contamination? ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2020; 27:14711-14722. [PMID: 32052329 DOI: 10.1007/s11356-020-07954-7] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/19/2019] [Accepted: 01/30/2020] [Indexed: 06/10/2023]
Abstract
Despite the exponential increase of studies on plastic debris in recent years, there are still few works focusing on the problem as it relates to inland waters: little is known about the accumulation and dispersion dynamics on lake shores, and there are no standardized sampling methods for monitoring purposes. The accumulation of plastic litter in natural habitats also threatens the resident organisms. In this paper, we investigated the abundance and accumulation of plastic particles, ranging in size from 1 to 50 mm, from the beach sediment of three volcanic lakes in Central Italy: Albano, Bracciano, and Vico. The collection was designed to define the most important variables that one must consider in order to obtain a representative sample of plastic litter in a lake environment. In view of the high heterogeneity of sampling protocols used, comparison among the obtained results is limited and sometimes impossible. By using one of the proposed sampling methodologies, and critically analyzing the results, we aimed to highlight a possible monitoring criterion and to identify specific elements that can be meaningful and representative. The samples were collected in May and September 2017. For each lake, we sampled plastic items and sediments from two beaches. Albano contained the largest amount of plastic (in weight), while Bracciano had the largest number of particles. Our observations lead us to infer that the number of particles is the parameter most sensitive to environmental variations, as well as the more suitable for monitoring with greater definition the differences between sites. Moreover, sampling should be taken in different seasons, following a sampling pattern that includes at least two beaches placed in strategic positions with respect to wind and waves.In order to identify new indicators to evaluate the entry points of plastic into the food web, we collected, from the same sites analyzed, some specimens of the Talitrid Amphipod Cryptorchestia garbinii, a detritivorous species having a critical role in debris turnover of these environments. To investigate the microplastic (MP) ingestion in natural conditions, we analyzed their digestive tracts with both Nile red staining method and micro-FTIR spectroscopy. The analyses confirmed that C. garbinii was able to ingest plastics in natural conditions. Therefore, it can signify one of the entry points for microplastics (MPs) in the trophic chain. This observation constitutes the first evidence of MP ingestion in this species.

Abstract
OBJECTIVES To evaluate the safety of and patient satisfaction with fractional CO2 laser for the treatment of vulvo-vaginal atrophy (VVA) in postmenopausal patients. STUDY DESIGN Patients affected by VVA were considered for the study. All women were treated using a Lumenis AcuPulse DUO (Lumenis, Yokneam, Israel) in fractionated mode with a 28 mm probe, FemTouch™. Pain during different steps of the procedure (introduction, rotation and extraction of probe and laser impulse transmission) was evaluated on a 7-point Likert scale. The occurrence of side-effects was evaluated at the end of the procedure, and in the three-month follow-up (after the last treatment) complications were classified as 'early' (occurring within 30 days) or late (after 30 days). Participant satisfaction was measured on a 7-point Likert scale (1= strongly disagree, 7= strongly agree). The institutional review board approved the study protocol. RESULTS Fifty-three women were enrolled in the study. No severe complications occurred after a median follow-up of six months. One patient (1.9 %) reported dizziness immediately after treatment, which completely resolved within 15 min. A minor bleeding occurred related to tip introduction and rotation. One patient (1.9 %) aborted the procedure because of discomfort on probe introduction but decided to repeat the procedure after two weeks. Two patients (3.7 %) reported symptoms of dysuria within 7 days of the procedure. The mean overall pain score at first treatment, evaluated on the 7-point Likert scale, was 3.57 ± 1.50. The mean pain scores related to probe introduction and rotation were 3.13 ± 1.37 and 2.32 ± 1.08, whereas pain scores for extraction and laser impulse transmission were 1.23 ± 0.27 and 1.13 ± 0.37 respectively. Mean overall pain score (1.27; CI 95 % 0.83-1.71, p < 0.001) and pain scores related to probe introduction (0.54; CI 95 % 0.18-0.90, p = 0.001) and probe rotation (0.46; CI 95 % 0.12-0.90, p = 0.003) all statistically significantly decreased between the first and third treatment (Fig. 1). Mean pain scores related to laser activation (0.01; CI 95 % -0.06 - 0.20, p = 0.07) and extraction (0.08; CI 95 % -0.04-0.19, p = 0.31) did not change over the course of treatment. Overall, patient satisfaction with the procedure was high: 89.7 % of patients would highly (value 5-7) recommend the procedure and 94.9 % would be ready to repeat the procedure to maintain results. Discomfort related to treatment was lower than expected for 41 % of patients (value 5-7) and as expected for 48.7 % (value 3-4). CONCLUSION Fractional CO2 laser for treatment of VVA seems a safe therapeutic option. No severe complications occurred. A minority of patients reported mild complications, but these resolved without the need for treatment. Most discomfort was related to probe introduction and rotation. Overall, patients were highly satisfied, and they would repeat laser treatment.

Abstract
OBJECTIVE Describe the course and outcomes in a UK national cohort of neonates with vein of Galen malformation identified before 28 days of life. METHODS Neonates with angiographically confirmed vein of Galen malformation presenting to 1 of 2 UK treatment centers (2006-2016) were included; those surviving were invited to participate in neurocognitive assessment. Results in each domain were dichotomized into "good" and "poor" categories. Cross-sectional and angiographic brain imaging studies were systematically interrogated. Logistic regression was used to explore potential outcome predictors. RESULTS Of 85 children with neonatal vein of Galen malformation, 51 had survived. Thirty-four participated in neurocognitive assessment. Outcomes were approximately evenly split between "good" and "poor" categories across all domains, namely, neurological status, general cognition, neuromotor skills, adaptive behavior, and emotional and behavioral development. Important predictors of poor cognitive outcome were initial Bicêtre score ≤ 12 and presence of brain injury, specifically white matter injury, on initial imaging; in multivariate analysis, only Bicêtre score ≤ 12 remained significant. INTERPRETATION Despite modern supportive and endovascular treatment, more than one-third of unselected newborns with vein of Galen malformation did not survive. Outcome was good in around half of survivors. The importance of white matter injury suggests that abnormalities of venous as well as arterial circulation are important in the pathophysiology of brain injury. Ann Neurol 2018;84:547-555.

Abstract
Using Fourier transform infrared spectroscopy (FT-IR) measurements and comparing the spectrum peaks (range 4000-600 cm-1) with reference spectra database and instrument libraries, we observed new evidence of the ingestion of microplastic particles analyzing the digestive tracts of Talitrus saltator. Specimens, sampled in central Italy, probably ingested the particles with natural detritus. Since worldwide many species of invertebrates and vertebrates (e.g., birds) feed on Amphipoda along coastal ecosystems, we hypothesized that microplastic in these crustaceans can be accumulated along the food chain.

Abstract
Objectives Anogenital distance (AGD) represents the space between labia posterior commissure and anus. This was pilot study to investigate how menopause and so lack of oestrogens affects AGD. Methods A total of 109 patients were enrolled. AGD was measured in lithotomy position using sterile paper ruler. Anogenital index (AGI) was used to control 2 variables of height and weight (body mass index, kg/m2). Vaginal health index (VHI) was used to evaluate vaginal wellness. Female sexual function index (FSFI) questionnaire was administered to all women to evaluate the impact of menopause on their sexual function. Results AGD (30.87 ± 2.98 vs. 17.57 ± 2.18; P = 0.0001) and AGI (1.40 ± 0.21 vs. 0.70 ± 0.15; P = 0.0001) were both significantly lower in the postmenopausal group. Postmenopausal women were affected by vulvovaginal atrophy (VVA) significantly. Thus, VHI scores were dramatically worse in postmenopausal group (23.95 ± 1.28 vs. 10.75 ± 3.41; P = 0.0001) as well as FSFI results (32.68 ± 2.25 vs. 19.78 ± 5.46; P = 0.0001). Conclusions This study confirms that AGD in post-menopausal women was significantly shorter than AGD in premenopausal women, correlating with an increase of VVA and sexual impairment. Changes of AGD and AGI demonstrated to predict hormonal changes that may occur after menopause.

Abstract
Plastic debris incidence in marine environment was already highlighted in the early 1970s. Over the last decade, microplastic pollution in the environment has received increasing attention and is now an emerging research area. Many studies have focused on quantifying microplastic abundance in the marine environment, while there are relatively few data on microplastic occurrence in freshwater environment. Recent studies have reported high concentrations of microplastics in lakes and rivers, although the understanding of several factors influencing source, transport and fate is still limited. This study compares different lakes and the common factors, which could influence the occurrence and distribution of microplastics. The three subalpine lakes monitored include Lake Maggiore, Iseo and Garda. The selected sampling transects reflect the hydrologic conditions, the morphometric characteristics of these lakes, and other factors influencing the release of plastics debris in lakes. Particles of microplastics (<5 mm) were found in all sampled surfaces. The particles collected were classified depending on their number, shape and composition. The shape distribution showed the dominating occurrence of fragments (73.7%). The chemical composition of all examined samples clearly shows dominating presence of polyethylene (45%), polystyrene (18%) and polypropylene (15%). The results provide significant relations among the different contribution of direct and diffuse sources to the quantity of microplastics, highlighting the importance of understanding the spatial distribution dynamics of microplastics within a lake system that acts as a sink and source of plastic particles.

Abstract
The ability of Posidonia oceanica spheroids (egagropiles, EG) to incorporate plastics was investigated along the central Italy coast. Plastics were found in the 52.84% of the egagropiles collected (n = 685). The more represented size of plastics has range within 1-1.5 cm, comparable to the size of natural fibres. Comparing plastics occurring both in EG and in surrounding sand, Polyethylene, Polyester and Nylon were the most abundant polymers in EG, while PSE, PE, PP and PET were the most represented in sand. In particular PE and PP were significantly more represented in sand, while PE, Nylon, Polyester and microfibers (as pills) were more represented in EG. Within plastics found in EG, 26.9% were microfibers as small pills (<1 cm), mainly composed of polyamide, polyester, cotton and PET mixing. These microfibers might be produced by discharges from washing machines and currently represents an emerging pollutant with widespread distribution in marine and freshwater ecosystems.

Abstract
OBJECTIVE Isthmocele represents a reservoir on the anterior wall of the uterine isthmus or of the cervical canal at the site of a previous cesarean delivery scar. Recently, it has been clarified that it might be the cause of several gynecologic symptoms, as most common abnormal uterine bleeding. Hysteroscopy and trans-vaginal ultrasound are considered the gold standard for the diagnosis of this defect. Resectoscopic treatment can be considered effective in small size defects, but no randomized clinical trials are available. This is a prospective controlled study to assess feasibility and efficacy of surgical hysteroscopic treatment of cesarean-induced isthmocele on symptom relief. PATIENTS AND METHODS Diagnostic hysteroscopy was performed as an office procedure in all 47 patients included in the study to confirm and identify the size of the defect. Surgical hysteroscopic treatment was performed in a selected group of patients (n = 23) having no more desire to conceive. Outcomes were measured three months later and compared in the operative hysteroscopy versus diagnostic hysteroscopy group. RESULTS The duration of periods shortened significantly (p = 0.0003) compared with the duration of menses before operative hysteroscopy in the treated group. Moreover, symptom relief was significantly better in treated patients compared with controls (p < 0.0001). CONCLUSIONS Resectoscopic treatment of isthmocele offers the possibility of an effective, safe and well-tolerated resolution of associated bleeding symptoms, having an excellent impact on the length of menses. To our knowledge, this is the first prospective controlled trial demonstrating better outcomes of resectoscopic treatment of isthmocele in solving symptoms compared with expectant management.

Abstract
Vulvodynia is a women's health problem that may affect as many as 15% of women who seek gynecological care, and yet little attention is given to this condition and it is frequently dismissed as psychosomatic. Thus, vulvodynia still remains a major health problem in Western countries, leading to significant morbidity and a reduced quality of life for many women. This condition carries large costs incurred as a result of both medical treatment and lost productivity. Vulvodynia is becoming a universal priority in the prevention, care, education, and research areas of pain and its consequences and it remains one of the poorly understood complex chronic pain syndromes, representing a multifactorial clinical syndrome of unexplained vulvar pain and sexual dysfunction.

Abstract
OBJECTIVE To investigate the impact of hematologic toxicity and leukopenia in locally advanced cervical cancer patients undergoing neoadjuvant chemotherapy (NACT). STUDY DESIGN Data of consecutive patients undergoing platinum-based NACT followed by surgery were retrospectively searched in order to evaluate the impact of chemotherapy-related toxicity on survival outcomes. Toxicity was graded per the Common Terminology Criteria for Adverse Events (CTCAEv.4.03). Survival outcomes were evaluated using Kaplan-Meir and Cox hazard models. RESULTS Overall, 126 patients were included. Among those, 94 (74.6%) patients experienced grade2+ hematologic toxicity; while, grade2+ non-hematologic toxicity occurred in 11 (8.7%) patients. After a median follow-up of 37.1 (inter-quartile range, 12-57.5) months, 21 (16.6%) patients experienced recurrence. Via multivariate analysis, no factor was independently associated with disease-free survival; while a trend toward worse prognosis was observed for patients experiencing grade2+ leukopenia at cycle-3 (HR:3.13 (95%CI: 0.94, 10.3); p=0.06). Similarly, grade2+ leukopenia (HR:9.98 (95%CI: 1.14, 86.6); p=0.03), lymph-node positivity (HR:14.6 (95%CI:1.0, 214.4); p=0.05) and vaginal involvement (HR:5.81 (95%CI:1.43, 23.6); p=0.01) impacted on overall survival, at multivariate analysis. Magnitude of leukopenia correlated with survival (p<0.001). CONCLUSIONS Although, our data have to be confirmed by prospective investigations, the present study shows an association between the occurrence of leukopenia and survival outcomes. NACT-related immunosuppression might reduce the response against the tumor, thus promoting cancer progression.

Efficacy of adjuvant chemotherapy in early stage uterine leiomyosarcoma: A systematic review and meta-analysis. Gynecol Oncol 2016; 143:443-447. [PMID: 27481579 DOI: 10.1016/j.ygyno.2016.07.110] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2016] [Revised: 07/14/2016] [Accepted: 07/21/2016] [Indexed: 02/08/2023]
Abstract
OBJECTIVE We sought to review the current evidence in order to test the efficacy of adjuvant chemotherapy in improving disease-free survival in patients affected by early stage uterine leiomyosarcoma. METHODS On July 2016, literature was searched in order to identify trials comparing different postoperative adjuvant strategies for patients diagnosed with early stage uterine leiomyosarcoma. RESULTS Our analysis included 360 patients: 145 (40%), 53 (15%), and 155 (43%) had chemotherapy (with or without radiotherapy), radiotherapy, and observation, respectively. Seven (2%) patients who had radiotherapy with or without chemotherapy were excluded from further analysis in order to reduce risk of biases. Administration of chemotherapy (with or without radiotherapy) did not improve outcomes in comparison to observation (OR: 0.79 (95%CI: 0.48, 1.29)), or radiotherapy (OR: 0.90 (95%CI: 0.42, 1.94)). Loco-regional recurrence rate was similar comparing patients undergoing chemotherapy (with or without radiotherapy) with having observation alone (OR: 0.84 (95%CI: 0.44, 1.60)). Similarly, pooled results suggested that chemotherapy administration did not affect distant recurrence rate in comparison to no chemotherapy (OR: 0.80 (95%CI: 0.50, 1.28)), and observation alone (OR: 0.99 (95%CI: 0.60, 1.64)). However, patients undergoing chemotherapy (with or without radiotherapy) experienced a trend towards lower risk of developing distant recurrences (OR: 0.49 (95%CI: 0.24, 1.03)) and a higher risk of developing loco-regional recurrences (OR: 3.45 (95%CI: 1.02, 11.73)) than patients undergoing radiotherapy. CONCLUSIONS In early stage uterine leiomyosarcoma, the role of adjuvant chemotherapy remains unclear. Owing to the high recurrence rate, even in the early stage of disease, further innovative therapeutic strategies have to be tested.

Abstract
With the growing demand of fresh-cut vegetables, a variety of packaging films are produced specifically to improve safety and quality of the fresh vegetables over the storage period. The aim of our work was to evaluate the influence of different packaging films on the quality of fresh-cut lettuce analyzing changes in bacterial community composition and modifications at the proteome level, by means of culture-dependent/culture-independent methods and differential gel electrophoresis combined with mass spectrometry analysis. Total viable counts indicated the presence of a highly variable and complex microbial flora, around a mean value of 6.26 log10 CFU g(-1). Analysis of terminal-restriction fragment length polymorphism data indicated that bacterial communities changed with packaging films and time, showing differences in community composition and diversity indices between the commercially available package (F) and the new packages (A and C), in the first days after packaging. Also proteomic analysis revealed significant changes, involving proteins related to energy metabolism, photosynthesis, plant defense and oxidative stress processes, between F and A/C packages. In conclusion, microbiological and proteomic analysis have proved to be powerful tools to provide new insights into both the composition of leaf-associated bacterial communities and protein content of fresh-cut lettuce during the shelf-life storage process.

The "serendipitous brain": Low expectancy and timing uncertainty of conscious events improve awareness of unconscious ones (evidence from the Attentional Blink). Cortex 2015; 71:15-33.

Abstract
To anticipate upcoming sensory events, the brain picks-up and exploits statistical regularities in the sensory environment. However, it is untested whether cumulated predictive knowledge about consciously seen stimuli improves the access to awareness of stimuli that usually go unseen. To explore this issue, we exploited the Attentional Blink (AB) effect, where conscious processing of a first visual target (T1) hinders detection of early following targets (T2). We report that timing uncertainty and low expectancy about the occurrence of consciously seen T2s presented outside the AB period, improve detection of early and otherwise often unseen T2s presented inside the AB. Recording of high-resolution Event Related Potentials (ERPs) and the study of their intracranial sources showed that the brain achieves this improvement by initially amplifying and extending the pre-conscious storage of T2s' traces signalled by the N2 wave originating in the extra-striate cortex. This enhancement in the N2 wave is followed by specific changes in the latency and amplitude of later components in the P3 wave (P3a and P3b), signalling access of the sensory trace to the network of parietal and frontal areas modulating conscious processing. These findings show that the interaction between conscious and unconscious processing changes adaptively as a function of the probabilistic properties of the sensory environment and that the combination of an active attentional state with loose probabilistic and temporal expectancies on forthcoming conscious events favors the emergence to awareness of otherwise unnoticed visual events. This likely provides an insight on the attentional conditions that predispose an active observer to unexpected "serendipitous" findings.

Abstract
Neuropsychological group study methodology is considered one of the primary methods to further understanding of the organisation of frontal 'executive' functions. Typically, patients with frontal lesions caused by stroke or tumours have been grouped together to obtain sufficient power. However, it has been debated whether it is methodologically appropriate to group together patients with neurological lesions of different aetiologies. Despite this debate, very few studies have directly compared the performance of patients with different neurological aetiologies on neuropsychological measures. The few that did included patients with both anterior and posterior lesions. We present the first comprehensive retrospective comparison of the impact of lesions of different aetiologies on neuropsychological performance in a large number of patients whose lesion solely affects the frontal cortex. We investigated patients who had a cerebrovascular accident (CVA), high (HGT) or low grade (LGT) tumour, or meningioma, all at the post-operative stage. The same frontal 'executive' (Raven's Advanced Progressive Matrices, Stroop Colour-Word Test, Letter Fluency-S; Trail Making Test Part B) and nominal (Graded Naming Test) tasks were compared. Patients' performance was compared across aetiologies controlling for age and NART IQ scores. Assessments of focal frontal lesion location, lesion volume, global brain atrophy and non-specific white matter (WM) changes were undertaken and compared across the four aetiology. We found no significant difference in performance between the four aetiology subgroups on the 'frontal' executive and nominal tasks. However, we found strong effects of premorbid IQ on all cognitive tasks and robust effects of age only on the frontal tasks. We also compared specific aetiology subgroups directly, as previously reported in the literature. Overall we found no significant differences in the performance of CVA and tumour patients, or LGT and HGT patients or LGT, HGT and meningioma's on our four frontal tests. No difference was found with respect to the location of frontal lesions, lesion volume, global brain atrophy and non-specific WM changes between the subgroups. Our results suggest that the grouping of frontal patients caused by different aetiologies is a pragmatic, justified methodological approach that can help to further understanding of the organisation of frontal executive functions.

Abstract
Myomectomy is rarely performed during an ongoing pregnancy because of fear of miscarriage and the risk of an uncontrolled haemorrhage necessitating a hysterectomy. In cases where myomectomy is undertaken, most are performed at the time of cesarean section or with a laparoscopic approach. We report a case of a successful laparotomic myomectomy in the 16th week of pregnancy. A 35-year-old primigravida was admitted to our department with acute abdominal pain and hydronephrosis (serum creatinine 1.6 mg/dL). Imaging revealed a large implant myoma compressing the bladder, ureters, rectus, and gestational chamber and causing hydronephrosis. Laparotomic myomectomy was successfully performed and pregnancy continued uneventfully until the 38th week when a cesarean section was performed. Surgical management of myomas during pregnancy is worth evaluating in well-selected and highly symptomatic cases.

Abstract
The exact anatomical localization of right hemisphere lesions that lead to left spatial neglect is still debated. The effect of confounding factors such as acute diaschisis and hypoperfusion, visual field defects, and lesion size may account for conflicting results that have been reported in the literature. Here, we present a comprehensive anatomical investigation of the gray- and white matter lesion correlates of left spatial neglect, which was run in a sample 58 patients with subacute or chronic vascular strokes in the territory of the right middle cerebral artery. Standard voxel-based correlates confirmed the role played by lesions in the posterior parietal cortex (supramarginal gyrus, angular gyrus, and temporal-parietal junction), in the frontal cortex (frontal eye field, middle and inferior frontal gyrus), and in the underlying parietal-frontal white matter. Using a new diffusion tensor imaging-based atlas of the human brain, we were able to run, for the first time, a detailed analysis of the lesion involvement of subcortical white matter pathways. The results of this analysis revealed that, among the different pathways linking parietal with frontal areas, damage to the second branch of the superior longitudinal fasciculus (SLF II) was the best predictor of left spatial neglect. The group study also revealed a subsample of patients with neglect due to focal lesion in the lateral-dorsal portion of the thalamus, which connects the premotor cortex with the inferior parietal lobule. The relevance of fronto-parietal disconnection was further supported by complete in vivo tractography dissection of white matter pathways in 2 patients, one with and the other without signs of neglect. These 2 patients were studied both in the acute phase and 1 year after stroke and were perfectly matched for age, handedness, stroke onset, lesion size, and for cortical lesion involvement. Taken together, the results of the present study support the hypothesis that anatomical disconnections leading to a functional breakdown of parietal-frontal networks are an important pathophysiological factor leading to chronic left spatial neglect. Here, we propose that different loci of SLF disconnection on the rostro-caudal axis can also be associated with disconnection of short-range white matter pathways within the frontal or parietal areas. Such different local disconnection patterns can play a role in the important clinical variability of the neglect syndrome.

Abstract
Several studies show that visual stimuli traveling at higher velocities are overestimated with respect to slower, or stationary, stimuli of equivalent physical duration. This effect-time dilation-relates more in general to several accounts highlighting a quantitative relationship between the amount of changes a stimulus is subject to and the perceived duration: faster stimuli, subject to a greater number of changes in space, lead to overestimated durations of displacement. In the present paper we provide evidence of a new illusory effect, in which the apparent duration of a sensory event is affected by the way a constant number of changes are delivered in time, or in time and space. Participants judged accelerating and decelerating sequences of stationary flickering stimuli (Experiments 1 and 3) and accelerating and decelerating horizontally drifting visual stimuli (Experiment 2) on the fronto-parallel plane. Acceleration and deceleration were achieved by irregular sequencing of events in time (anisochronous flicker rate) or irregular sequencing of events in time and space (anisochronous and/or anisometric drift). Despite being characterized by the same amounts of visual changes, accelerating and decelerating sequences lead to opposite duration biases (underestimation and overestimation errors, respectively). We refer to this effect in terms of ATI: Aniso-Time-Illusion. This bias was observed in both subsecond (760 ms) and suprasecond ranges (1900 ms). These data highlight how the spatio-temporal evolution of dynamic visual events, asides the overall quantity of changes they are subject to, affect the perceived amount of time they require to unfold.

Abstract
Epidemiology for diverticular disease of the colon is rather difficult to assess because of the almost regularly selection of the patients submitted to analysis and described in literature. Therefore data extracted from different experiences are useful only for orientative epidemiologic implications. In the meanwhile these studies have been very useful to understand the possible reasons of its insurgence and evolution. Actually for etiopathogenesis the more diffuse opinion is to give importance to low fibre diet and to intrinsic motor derangement of the colon.

Abstract
From 1987 to 1992, 91 rectal neoplasms were operated in the Istituto di Patologia Speciale Chirurgica of the University of Bologna: 50 anterior resections and 41 abdomino-perineal amputations. The local recurrence rate shows no significant difference between the two groups. The mortality rate is 7.6% in anterior resections and 14.2% in abdomino-perineal amputations. Our results and literature review show that local recurrence and mortality rates depend more from the tumor stage than from the surgical procedure.
