Chronic atrazine exposure increases the expression of genes associated with GABAergic and glutamatergic systems in the brain of male albino rat. FRONTIERS IN TOXICOLOGY 2022; 4:933300. [PMID: 36071823 PMCID: PMC9441881 DOI: 10.3389/ftox.2022.933300] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2022] [Accepted: 07/19/2022] [Indexed: 11/24/2022] Open
Abstract
The herbicide atrazine (ATR; 2-chloro-4-ethylamino-6-isopropylamino-s-triazine) is widely used to destroy grasses and broadleaf weeds in crops and some fruits. Studies in rodents have shown that acute, repeated or chronic exposure to ATR is associated with alterations in the nigrostriatal dopaminergic pathway, whereas its effects on GABAergic and glutamatergic pathways have only recently been reported. Sprague-Dawley male rats were exposed daily to 1 or 10 mg ATR/kg of BW for 13 months to evaluate the ATR effects on GABAergic and glutamatergic systems. At the end of the ATR treatment, the levels of mRNA of several genes involved in the production, vesiculation, reuptake, and receptors of GABA and Glu in the striatum (STR), nucleus accumbens (NAcc), prefrontal cortex (PFC), ventral midbrain (vMID) and hippocampus (HIPP) were evaluated by absolute qPCR. For the GABAergic genes, increased expression of GAD67 and Slc32a1 in STR and/or vMID in rats exposed to 1 and/or 10 mg ATR were detected. With regard to the expression of genes involved in the glutamatergic system, Slc17a6 and Grin1 in HIPP of rats exposed to 1 and/or 10 mg ATR, increased as was Gria1 in STR and PFC in the group exposed to 1 mg ATR. In the same fashion, Slc1a3 expression and MGLUR1 increased in STR of rats exposed to 1 and 10 mg ATR groups. The expression of the glutaminases gls (variants 1 and 2) was greater in STR, NAcc, HIPP, and PFC of rats exposed to 1 and/or 10 mg ATR. These findings show that the GABAergic and, especially glutamatergic systems are targets of ATR exposure.

Encorafenib plus cetuximab with or without binimetinib in patients with BRAF V600E-mutated metastatic colorectal cancer: real-life data from an Italian multicenter experience. ESMO Open 2022; 7:100506. [PMID: 35696748 PMCID: PMC9271503 DOI: 10.1016/j.esmoop.2022.100506] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2022] [Revised: 04/03/2022] [Accepted: 04/06/2022] [Indexed: 11/15/2022] Open
Abstract
Background Encorafenib plus cetuximab with or without binimetinib showed increased objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) compared with chemotherapy plus anti-EGFR in previously treated patients with BRAF V600E-mutated (mut) metastatic colorectal cancer (mCRC). Although no formal comparison was planned, addition of binimetinib to encorafenib plus cetuximab did not provide significant efficacy advantage. Patients and methods This real-life study was aimed at evaluating safety, activity, and efficacy of encorafenib plus cetuximab with or without binimetinib in patients with BRAF V600E-mut mCRC treated at 21 Italian centers within a nominal use program launched in May 2019. Results Out of 133 patients included, 97 (73%) received encorafenib plus cetuximab (targeted doublet) and 36 (27%) the same therapy plus binimetinib (targeted triplet). Most patients had Eastern Cooperative Group Performance Status (ECOG-PS) of 0 or 1 (86%), right-sided primary tumor (69%), and synchronous disease (66%). Twenty (15%) tumors were DNA mismatch repair deficiency (dMMR)/microsatellite instability (MSI)-high. As many as 44 (34%) patients had received two or more prior lines of therapy, 122 (92%) were previously exposed to oxaliplatin, and 109 (82%) to anti-vascular endothelial growth factor (anti-VEGF). Most frequent adverse events were asthenia (62%) and anti-EGFR-related skin rash (52%). Any grade nausea (P = 0.03), vomiting (P = 0.04), and diarrhea (P = 0.07) were more frequent with the triplet therapy, while melanocytic nevi were less common (P = 0.06). Overall, ORR and disease control rate (DCR) were 23% and 69%, respectively, with numerically higher rates in the triplet group (ORR 31% versus 17%, P = 0.12; DCR 78% versus 65%, P = 0.23). Median PFS and OS were 4.5 and 7.2 months, respectively. Worse ECOG-PS, peritoneal metastases, and more than one prior treatment were independent poor prognostic factors for PFS and OS. Clonality of BRAF mutation measured as adjusted mutant allele fraction in tumor tissue was not associated with clinical outcome. Conclusions Our real-life data are consistent with those from the BEACON trial in terms of safety, activity, and efficacy. Patients in good general condition and not heavily pretreated are those more likely to derive benefit from the targeted treatment. Encorafenib plus cetuximab ± binimetinib is safe and effective for BRAF V600E mut mCRC even in the real-world setting. Median OS is slightly shorter than in the BEACON trial, probably due to less selected patients in real life. Patients deriving more benefit from targeted therapy are likely those in good general conditions and not heavily pretreated. BRAF adjusted MAF is worth further investigation to better characterize the genomic heterogeneity of BRAF V600E mut mCRC.

Abstract
Abstract
Background
Ostium secundum ASD (ASDII) is the most common type of congenital heart disease in adults. Percutaneous closure has emerged as the first–line treatment for the majority of ASDII. However, the occurrence of Pulmonary Hypertension (PH) with combined pre– and post–capillary component may render ASD management challenging in elderly patients.
Methods
We report the hemodynamic data and clinical findings of elderly patients (> 60 years old) undergoing transcatheter closure of an ASDII at our department.
Results
From 2000 to 2021, 82 elderly patients were scheduled (mean age 65,4+ 4,4) of which 60 (73%) were female. Systemic arterial hypertension and supraventricular arrhythmias were the most common comorbidities accounting respectively 51% and 38% of cases. The right ventricular overload supported the ASD closure in 76 cases (93%) and paradoxical embolism in the remaining 6 (7%). 17 patients (21%) were in NYHA class III– IV. At right heart catheterization, 33 patients had normal pulmonary arterial pressure and 49 patients showed a mean pulmonary artery pressure > 20 mmhg. In the latter cohort, 33 showed a pulmonary artery wedge pressure (PAWP) < 15 mmHg (Group I) and 16 > 15 mmHg (Group II). The device implantation was completed in all patients except one with elevated pulmonary vascular resistance (PVR) of the Group I. For 14 patients of Group II, balloon occlusion test was required during the catheterization. ASD closure was achieved promptly in 10 patients. However, to reduce the risk of acute pulmonary oedema, in one case we created a small fenestration in the occluder device and in other case we retained the patency of additional defect (both patients exhibiting slightly PAWP increase during balloon occlusion test). In one patient showing significantly PAWP increase during balloon test, delayed ASD closure was performed ensuring the improvement of hemodynamic parameters at 3 months initiation of medical therapy with angiotensin–converting enzyme inhibitor and loop diuretic diuretics. For the remaining 4 patients, the percutaneous closure was not been done because of prohibitive hemodynamic parameters. Overall, ASD closure was performed successfully in 94% of cases.
Conclusions
Age and comorbidities are not absolute contraindications to ASDII percutaneous closure. In the complex cases, both medical therapies and balloon occlusion test may be use to support the decision–making process.

Abstract
Abstract
Background
Multifenestrate aneurysms of interatrial septum (ISA) are a challenge in paediatric age, not only for the complex anathomy, but also for small body surface and small dimensions of cardiac chambers of the patients, that may limit the use of large and multiple devices. Aim of the study: to evaluate the efficacy of percutaneous closure of multifenestrate aneurysms during mid–term and long–term follow–up; to evaluate if the morphological characteristics of interatrial septum may influence the success of the procedure.
Materials and Methods
We retrospectively analyzed 63 patients (mean–age 9,12±3,12 years) undergone to cardiac catheterism from 2000 to 2021, for percutaneous closure of interatrial aneurysm in our division of Cardiology, subdivided into 3 groups on the basis of side and morphological characteristics of the interatrial aneurysm: Group I (2 o more defects DIA>5 mm); Group II (one defect >5 mm and more than one further fenestrations); Group III (multiple fenestrations).
Results
Percutaneous closure was efficacy in 60 patients (95%), while in 3 patients (5%) surgery closure was necessary. In half of the treated patients (30) we used 2 devices. Complications occurred in 4 patients (6%). Only in 2 patients occurred major complications (Atrio–Ventricular Block that needed PMK implantation and partial displacement of device, treated by removal and percutaneous replanting). Residual shunts, not emodynamically significant appear in the immediate post–operative period in 26% and during the follow–up in 18%. The group I was associated with greater risk of failure of the procedure (P < 0.01) and need of implantations of more than one devices (P < 0.01).
Conclusions
Percutaneous closure of multifenestrate aneurysm of interatrial septum in paediatric age are effective and shows low incidence of failure and complications. If is present residual shunt is not significant. The anathomy of interatrial septum influences procedural outcome.

Abstract
Background Limited real-world data exist on the effectiveness and safety of abiraterone acetate plus prednisone (abiraterone hereafter) in the treatment of patients with metastatic castration-resistant prostate cancer (mCRPC) naive to chemotherapy. Most of the few available studies had a retrospective design and included a small number of patients. In the interim analysis of the ABItude study, abiraterone showed good clinical effectiveness and safety profile in the chemotherapy-naive setting over a median follow-up of 18 months. Patients and methods We evaluated clinical and patient-reported outcomes (PROs) of chemotherapy-naive mCRPC patients treated with abiraterone as for clinical practice in the Italian, observational, prospective, multicentric ABItude study. mCRPC patients were enrolled at abiraterone start (February 2016-June 2017) and followed up for 3 years; clinical endpoints and PROs, including quality of life (QoL) and pain, were prospectively collected. Kaplan–Meier curves were estimated. Results Of the 481 patients enrolled, 454 were assessable for final study analyses. At abiraterone start, the median age was 77 years, with 58.6% elderly patients and 69% having at least one comorbidity (57.5% cardiovascular diseases). Visceral metastases were present in 8.4% of patients. Over a median follow-up of 24.8 months, median progression-free survival (any progression reported by the investigators), time to abiraterone discontinuation, and overall survival were, respectively, 17.3 months [95% confidence interval (CI) 14.1-19.4 months], 16.0 months (95% CI 13.1-18.2 months), and 37.3 months (95% CI 36.5 months-not estimable); 64.2% of patients achieved ≥50% reduction in prostate-specific antigen. QoL assessed by Functional Assessment of Cancer Therapy—Prostate, the European Quality of Life 5 Dimensions 3 Level, and European Quality of Life Visual Analog Scale remained stable during treatment. Median time to pain progression according to Brief Pain Inventory data was 31.1 months (95% CI 24.8 months-not estimable). Sixty-two patients (13.1%) had at least one adverse drug reaction (ADR) and 8 (1.7%) one serious ADR. Conclusion With longer follow-up, abiraterone therapy remains safe, well tolerated, and active in a large unselected population. A prospective real-life study of abiraterone acetate in mCRPC patients. In 481 chemotherapy-naive mCRPC patients (median follow-up: 25 months), abiraterone plus prednisone was effective and safe. QoL, measured with various tools, remained stable during treatment with abiraterone plus prednisone. The median time to pain progression was 31.1 months.

Abstract
The Giant Cell tumor (GCT) is a benign, locally aggressive lesion that cause bone destruction and shows a malignant potential. It is a relatively common skeletal tumor that is therefore typically seen in young adults. Few cases are described in literature of GCT in the immature skeleton, and the metatarsal is an unusual location for a primary bone GCT, especially in pediatric age. Therefore, there are very few data reported regarding the management protocol of GCT in metatarsal bones. We report a case about the use of no vascularized fibular graft for an original Y-shaped reconstruction of the metatarsal bone after Giant Cell Tumor resection in a 9 years-old patient, and performed a literature review about metatarsal bone reconstruction in skeletally immature patient.

Abstract
Abstract
Background
Careful, step-wise assessment is required in all patients with an atrial septal defect (ASD) to exclude pre-existing pulmonary vascular disease or left ventricular disease. Fluid challenge test (FCT) and balloon occlusion testing (BOT) may unmask left ventricular disease and challenge the pulmonary circulation, but their complementary role in the evaluation of patients with “operable” ASD is not well established.
Aim
To evaluate the haemodynamic changes of the pulmonary circulation by FCT and BOT in ASD patients undergoing percutaneous closure according to the current guidelines.
Methods
Consecutive patients selected for percutaneous ASD closure underwent invasive hemodynamic assessment at baseline and after BOT, FCT and both.
Results
Fifty patients (mean age 47.3±11.7 years, 72% female) were included. All patients had a pulmonary-to-systemic flow ratio (QP/QS) ≥1.5, pulmonary vascular resistance (PVR) <5 WU and pulmonary arterial wedge pressure (PAWP) <15 mmHg. Individuals with a PVR ≥2 WU at baseline were older, more symptomatic, with a higher baseline systemic vascular resistance compared to the lower PVR group (PVR <2 WU; p<0.0001). The response of Qp/Qs to FCT was different between groups (p<0.0001, Figure 1). Patients with a lower baseline PVR experienced an increase in Qp/Qs, which remained above 1.5 in all patients, whereas in almost all (90%) patients with a higher baseline PVR, the Qp/Qs fell to below 1.5.
FCT caused a marked increase in pulmonary blood flow of almost 2 liters (p<0.0001) accompanied by increases in PAWP (p<0.0001). BOT led to a modest increase in PAWP (Δ1.5 [−1.0–7.0] mmHg, p<0.0001). FCT added to BOT caused a further increase in PAWP and Qs (both p<0.0001), while PVR was unchanged (p>0.1).
No difference was observed in the PAWP response to FCT, BOT or both between groups; no patients reached a PAWP ≥18 mmHg following FCT or BOT alone, but 4 (8%) patients did following the addition of FCT to BOT. No acute clinical adverse events were experienced by any patients.
Conclusions
None of the reported ASD patients presented with FCT criteria of post-capillary PH (that is a PAWP >18 mmHg). Even small rises in PVR may have significant implications on cardiovascular haemodynamics. In fact, patients with PVR <2 WU showed an increase in Qp/Qs, which remained above 1.5 in all patients, suggesting that they still had a distensible pulmonary circulation, whereas in almost all patients with a PVR ≥2 WU, the Qp/Qs fell to below 1.5.

Abstract
Pragmatic competence demands linguistic, but also communicative, social and cognitive competence. Successful use of language in social interaction requires mutual understanding of the speaker's intentions; without it, a conversation cannot proceed. The term speech act refers to what a speaker intends to accomplish when saying something. The purpose of this study was to contribute to the identification of the neural substrate of speech act recognition and to the characterization of the cognitive processes that may be involved. The recognition of speech acts resulted in greater activation of frontal regions, precuneus and posterior cingulate gyrus. From all cognitive and behavioral measures obtained, only the scores in mental flexibility predicted the change in blood oxygen level dependent (BOLD) signal in the precuneus. These results, support the idea that speech act recognition requires the inference of intention, executive functions, including memory and entails the activation of areas of social cognition that participate in several brain networks i.e., the Intention Processing, the Default Mode and Theory of Mind networks, and areas involved in planning and guiding behavior.

Abstract
The coronavirus disease (COVID‐19), during its course, may involve several organs, including the skin with a petechial skin rash, urticaria and erythematous rash, or varicella‐like eruption, representing an additional effect of the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection, as commonly observed in other viral diseases. Considering that symptomatic patients with COVID‐19 generally undergo multidrug treatments, the occurrence of a possible adverse drug reaction presenting with cutaneous manifestations should be contemplated. Pleomorphic skin eruptions occurred in a 59‐year‐old Caucasian woman, affected by a stable form of chronic lymphocytic leukemia, and symptomatic SARS‐CoV‐2 infection, treated with a combination of hydroxychloroquine sulfate, darunavir, ritonavir, sarilumb, omeprazole, ceftriaxone, high‐flow oxygen therapy devices, filgrastim (Zarzio®) as a single injection, and enoxaparin. The patient stopped all treatment but oxygen and enoxaparin were continued and the patient received a high‐dose Desametasone with complete remission of dermatological impairment in 10 days. It is very important to differentially diagnose COVID‐19 disease‐related cutaneous manifestations, where is justified to continue the multidrug antiviral treatment, from those caused by an adverse drug reaction, where it would be necessary to identify the possible culprit drug and to start appropriate antiallergic treatment.

Abstract
INTRODUCTION Recent years have been characterized by a great technological and clinical development in spine surgery. In particular, enhanced recovery after surgery (ERAS) programs, started to gain interest also in this surgical field. Here we tried to analyse the current state of art of ERAS technique in spine surgery. MATERIAL AND METHOD A systematic review of the literature has been performed in order to find all the possible inclusions. Using the PRISMA guidelines, a search of the PubMed/Medline, Web of Science, Cochrane Reviews, Embase, Medline databases was conducted to identify all full-text articles in the English-language literature describing the use of ERAS programs or techniques for spine surgery in adult patients. RESULTS Out of the 827 studies found, only 21 met the inclusion criteria has been retained to be included in the present study. The most frequently benefits of ERAS protocols were shorter hospitalisations (n=15), and decreased complication rates (n=8) lower postoperative pain scores (n=4). These benefits were seen in the 3 main categories considered: lumbar spine surgeries, surgeries for correction of scoliosis or deformity, and surgeries of the cervical spine. CONCLUSION There are an arising amount of data showing that the use of ERAS programs could be helpful in reducing the days of hospitalizations and the number of complications for certain spinal procedures and in a highly selected group of patients. Despite the large interest on the topic; there is an important lack of high level of scientific evidences. Because of that, there is the need to encourage the design and creation of new randomized clinical trials that will validate the present findings.

Abstract
Abstract
Background
A fluid challenge test (FCT) with a rapid infusion of saline allows for discrimination between pre- and post-capillary pulmonary hypertension (PH) and may unmask hidden post-capillary PH. Patients with atrial septal defect (ASD) may develop pre- or post-capillary PH after shunt closure respectively in case of pulmonary vascular disease or left ventricular disease.
Aim
To evaluate the haemodynamic changes of the pulmonary circulation in ASD patients undergoing percutaneous closure with indicated according to the current ESC guidelines.
Methods
Twenty-three patients (mean age 42.9±12.4 years; 15 female) underwent right heart catheterization in basal conditions and after FCT (volume loading with rapid saline infusion of 7 ml/kg in 10 min) before percutaneous closure of the ASD.
Right atrial pressure (RAP), systolic, mean and diastolic pulmonary arterial pressure (sPAP, mPAP and dPAP), pulmonary arterial wedge pressure (PAWP), cardiac output (CO), pulmonary vascular resistance (PVR), systemic vascular resistance (SVR) and the ratio between pulmonary and systemic flow (QP/QS) were calculated four times: before and after inflating the sizing balloon both at baseline and immediately after FCT (Fig. 1).
Results
The patients had an increase in pressures and flows after FCT with open ASD: mPAP (18.7±4.4 vs 16.7±4.6 mmHg, p<0.001), PAWP (11.3±3.1 vs 9.2±3.0 mmHg, p<0.001), QP (12.5±2.3 vs 10.3±2.0 l/min, p<0.001), and QS (6.6±1.4 vs 5.9±1.2 l/min, p<0.001) but RAP remained unchanged (8.7±3.0 vs 8.3±2.4 mmHg, p=0.35). PVR (0.2±0.4 vs 0.8±0.3 Wood Units, p<0.001) and SVR (11.2±3.2 vs 12.5±3.2 Wood Units, p=0.02) decreased, and PVR/SVR (0.06±0.02 vs 0.06±0.3, p=0.25) remained unchanged. QP/QS increased in all patients after FCT (mean±SD: 2.0±0.4 vs 1.8±0.4, p<0.001).
During a temporary ASD closure by sizing balloon, the patients had increases of RAP (9.0±2.6 vs 7.6±2.6 mmHg, p<0.001) mPAP (19.5±4.0 vs 17.4±3.7 mmHg, p<0.001), PAWP (13.2±2.1 vs 11.2±2.9 mmHg, p<0.001), and CO (7.7±2.7 vs 6.8±2.3 l/min, p<0.001) after FCT. PVR remained unchanged (0.9±0.4 vs 1.1±0.6, p=0.12) and SVR reduced (9.8±2.7 vs 11.3±2.9, p<0.001) after FCT.
Conclusions
None of the reported ASD patients presented with FCT criteria of post-capillary PH (that is a PAWP >18 mmHg). The FCT was associated with an increase in QP/QS suggesting that the patients still had a distensible pulmonary circulation. Further studies are needed to explore the relevance of a FCT in ASD patients, particularly those with higher PVR values.

Abstract
Atrazine (ATR; 2-chloro-4-ethylamino-6-isopropylamino-s-triazine) is an herbicide widely used to kill annual grasses and broadleaf weeds in crops such as corn, sorghum, and sugarcane. Studies in rodents have shown that chronic ATR exposure is associated with alterations in the nigrostriatal dopaminergic pathway such as hyperactivity, decreased striatal dopamine levels, and diminished numbers of tyrosine hydroxylase positive cells in substantia nigra pars compacta. However, the effects of ATR on neurotransmitters such as GABA and glutamate have been scarcely studied. To evaluate the impact of ATR on motor and anxiety tasks, tissue levels of GABA, glutamate, glutamine, and extracellular and potassium-evoked release of glutamate in the striatum, we daily exposed Sprague-Dawley male rats to 1 or 10 mg ATR/kg of body weight for 12-14 months. As previously reported, chronic ATR exposure causes hyperactivity in the group exposed to 10 mg ATR/kg and increased anxiety in both groups exposed to ATR. GABA, glutamate, and glutamine levels were differentially altered in brain regions related to nigrostriatal and mesolimbic systems, the amygdala, and the prefrontal cortex. The groups exposed to 10 mg ATR/kg showed increased extracellular levels and release of glutamate in the striatum. These neurochemical alterations could underlie the behavioral changes observed in rats. These results indicate that chronic exposure to the herbicide ATR disrupts the neurochemistry of several brain structures and could be a risk factor for the development of neurodegenerative diseases.

Abstract
INTRODUCTION Venous thromboembolism (VTE) is common in glioma patients. Also, spontaneous intracerebral hemorrhage (ICH) is frequently observed in subjects with primary brain tumors. Thus, the management of anticoagulant therapy for VTE is challenging and controversial in these patients. We performed a meta-analysis to clarify the risk of ICH in glioma patients treated with anticoagulant therapy for VTE compared to glioma patients without VTE. MATERIALS AND METHODS A systematic search of the literature was conducted using PubMed, Scopus, and EMBASE databases between January 1980 and January 2019 without language restrictions. Summary statistics for ICH were obtained by calculating the odds ratio (OR) using a random effects model, and heterogeneity across studies was estimated by the I2 statistic. The Newcastle-Ottawa Scale was used to evaluate the quality of studies. RESULTS A total of 368 studies were initially identified. Of these, 346 were excluded after title review. The remaining 22 studies were reviewed in detail. According to the PICO criteria, 15 studies were excluded. Finally, 7 studies were included in the meta-analysis. The OR for ICH in glioma patients receiving therapeutic anticoagulation for VTE versus those who did not receive anticoagulation was 3.66 (95% confidence interval [CI], 1.84-7.29; I2 = 31%). CONCLUSIONS This meta-analysis demonstrates that anticoagulation for VTE increases the risk of ICH in subjects with malignant brain tumors. Future studies are warranted to fully understand the best medical treatment of VTE in glioma patients.

Abstract
Unusual site deep vein thrombosis (USDVT) is an uncommon form of venous thromboembolism
with heterogeneous signs and symptoms, unknown rate of pulmonary embolism (PE), and poorly
defined risk factors. We conducted a retrospective analysis of 107 consecutive cases of
USDVTs, discharged from our University Hospital over a period of 2 years. Patients were
classified based on the site of thrombosis and distinguished between patients with
cerebral vein thrombosis, jugular vein thrombosis, thrombosis of the deep veins of the
upper extremities, and abdominal vein thrombosis. We found statistically significant
differences between groups in terms of age (P < .0001) and gender
distribution (P < .05). We also found that the rate of symptomatic
patients was significantly different between groups (P < .0001).
Another interesting finding was the significant difference between groups in terms of rate
of PE (P < .01). Finally, we found statistically significant
differences between groups in terms of risk factors for thrombosis, in particular cancer
(P < .01). Unprovoked cases were differently distributed among
groups (P < .0001). This study highlights differences between patients
with USDVT, which depend on the site of thrombosis, and provides data which might be
useful in clinical practice.

Abstract
A discovery that neutrinos are Majorana fermions would have profound implications for particle physics and cosmology. The Majorana character of neutrinos would make possible the neutrinoless double-β (0νββ) decay, a matter-creating process without the balancing emission of antimatter. The GERDA Collaboration searches for the 0νββ decay of 76Ge by operating bare germanium detectors in an active liquid argon shield. With a total exposure of 82.4 kg⋅year, we observe no signal and derive a lower half-life limit of T 1/2 > 0.9 × 1026 years (90% C.L.). Our T 1/2 sensitivity, assuming no signal, is 1.1 × 1026 years. Combining the latter with those from other 0νββ decay searches yields a sensitivity to the effective Majorana neutrino mass of 0.07 to 0.16 electron volts.

Abstract
Irvingia gabonensis, also known as 'bush mango', is a multipurpose fruit tree, native to tropical Africa. It is a priority indigenous fruit tree in western and central Africa since its wood is used for making utensils and fruits are mostly used as food and medicine. The objective of this work is to provide an updated review of the available knowledge about physicochemical characteristics of I. gabonensis fruit in order to evaluate its potential use in the food industry. The fruit mesocarp contains various phytochemicals and ascorbic acid concentration higher than some vitamin C rich fruits, then it is consumed fresh or dried, used to produce juice and wine, or as a flavourant. I. gabonensis fruit kernel is rich in oil (63%-69% crude fat), mainly composed of myristic and lauric acids. Its triacylglycerol composition and, resultantly, melting curve and polymorphism indicate an aptitude for diverse applications, as it is solid at room temperature. Forty-one phenolic compounds were identified in the seeds and derived extracts and supplements, being ellagic acid and its derivates the most present. This review enhances our knowledge about nutritional content and health benefits of I. gabonensis whole fruit, especially its pulp and seed, evidencing the need for safer and more efficient production of value-added products.

Abstract
OBJECTIVE Epidemiological features of musculoskeletal infections are in continuous evolution. The incidence of emerging causative pathogen is arising. Nevertheless, up to 50% of osteoarticular infections shows negative cultures. Septic arthritis, with or without concurrent osteomyelitis, are most common in newborn while osteomyelitis frequently affects older patients. We retrospectively analyzed all the children affected by musculoskeletal infections treated at the Children's Hospital Bambino Gesù in ten years, focusing on the results of an early diagnostic and therapeutic management. MATERIALS AND METHODS The study population consists of 150 children with acute septic arthritis, osteomyelitis and discitis, treated from 2006 to 2016, excluding patients with less than 12 months of follow-up and previous treatment sustained in others hospitals. A wide spectrum of data has been extracted from clinical charts, laboratory studies and imaging. Patients were categorized into 3 groups on the base of their age. The diagnostic and therapeutic protocol consisted of intravenous empirical treatment while diagnosis was ongoing then switched to oral treatment, according to the pathogen and the systemic symptoms. RESULTS Only 31% of pathogens were identified. The most common was Staphylococcus aureus methicillin-sensible (MSSA) but an increase of cases caused by Kingella Kingae and Staphylococcus aureus methicillin-resistant (MRSA) was observed. The mean antibiotic treatment was 6.8 weeks. It's important to underline a significant correlation between age and C-reactive protein serum levels. CONCLUSIONS Among others frequent pathogens, MRSA shows a high rate of physis involvement. Musculoskeletal infections represent a challenge in skeletally immature patients because of their potential severe complications. Timing of diagnosis and consequent targeted treatment is fundamental to avoid complications and functional sequelae.

Abstract
In order to understand of the processes controlling phytoplankton successions in the NE Black Sea, long-term data series are needed. We compiled 15 years (2002-2017) of measurements from which the existence emerges of a tight link between phytoplankton species dominance and nutrients concentrations. The latter is strongly influenced by wind direction. The link between algal dominance and nutrients is mediated by the growth strategy adopted by algal species. In spring, when nutrients are abundant, small diatoms such as Pseudo-nitzschia pseudodelicatissima, with a "rapid growth strategy", prevail. In late spring and early summer, when N is low and P and Si are high, coccolithophorids such as Emiliania huxhleyi dominate, thanks to an "affinity growth strategy". Large diatoms, especially Pseudosolenia calcar-avis, dominate in summer and autumn, when their "storage growth strategy" allows the exploitation of discontinuous upwelling of nutrients. These seasonal changes of dominant species influence the structure of the food web.

Abstract
Whether antithrombotic treatment is safe and/or affects the risk of intracranial bleeding in subjects with sporadic brain arteriovenous malformations (AVMs) is unknown. We conducted a retrospective analysis on the use of antithrombotics among patients affected by brain AVMs in follow-up at our institution. Attention was paid to the type of antithrombotic drug (either antiplatelets or anticoagulants), current or past use, dosage, and duration of treatment. Several clinical and angioarchitectural features of brain AVMs were also taken into consideration. The association between the use of antithrombotics and haemorrhagic onset was analyzed. A total of 77 patients were included in this study. Among them, ten patients were taking antithrombotic drugs at the time of AVM diagnosis. The rate of haemorrhagic onset was not significantly different between subjects who were and were not taking antithrombotic drugs (40 vs 55.2%, p = ns). Among the many clinical and angioarchitectural features analyzed, the only parameter that showed a statistically significant association with haemorrhagic onset was the size of the nidus. Patients who took antithrombotic treatments after being diagnosed with a brain AVM did not show an increased rate of intracranial haemorrhage over time considering a mean follow-up 4 years. In our study, antithrombotic treatment was not associated with increased intracranial bleeding among subjects with brain AVMs. In the presence of a strong clinical indication, antiplatelet and anticoagulant medications should not be denied a priori to patients with brain AVMs. Studies on larger populations are necessary to confirm these data.

Abstract
Objective This paper reports on a rare case of pregnancy after uterine artery embolization (UAE) for uterine arteriovenous malformation (AVM). Debate exists about persistence of fertility in women after UAE. Adverse effects of this technique can modify both uterine echostructure, inducing necrosis and infarction, endometrial atrophy and uterine artery rupture, and ovarian reserve, causing persistent amenorrhea. Ovarian reserve appears to be affected by UAE in pre-menopausal women. However, younger ovaries (according to biological ovarian age) exhibit a greater capacity for recovery after ovarian damage. Therefore, larger studies are needed for more conclusive results. Case report A 28-year-old woman was admitted to our department due to life-threatening uterine bleeding, resulting in tachycardia, pallor, and sweating. The patient came with a history of two spontaneous miscarriages. After sonography and computed tomography, AVMs were identified at uterine fundus and anterior wall. Conclusion The pathogenesis of infertility after UAE is not yet known. The peculiarity of this case was that, only few months later, the patient became pregnant and gave birth to a live fetus at 37 weeks with cesarean delivery.

Abstract
To analyze putative biomarkers for prostate cancer (PCA) characterization, the second leading cause of cancer-associated mortality in men. Quantification of the expression level of c-myc and HIF-1α was performed in 72 prostate cancer specimens. A cohort of 497 prostate cancer patients from The Cancer Genome Atlas (TCGA) database was further analyzed, in order to test our hypothesis. We found that high c-myc level was significantly associated with HIF-1α elevated expression (p = 0.008) in our 72 samples. Statistical analysis of 497 TCGA prostate cancer specimens confirmed the strong association (p = 0.0005) of c-myc and HIF-1α expression levels, as we found in our series. Moreover, we found high c-myc levels significantly associated with low Glutatione S-transferase P1 (GSTP1) expression (p = 0.01), with high Transketolase (TKT) expression (p < 0.0001). High TKT levels were found in TCGA samples with low GSTP1 mRNA (p < 0.0001), as shown for c-myc, and with ERG increased expression (p = 0.02). Finally, samples with low GSTP1 expression displayed higher ERG mRNA levels than samples with high GSTP1 score (p < 0.0001), as above shown for c-myc. Our study emphasizes the notion of a potential value of HIF-1α and c-myc as putative biomarkers in prostate cancer; moreover TCGA data analysis showed a putative crosstalk between c-myc, HIF-1α, ERG, TKT, and GSTP1, suggesting a potential use of this axis in prostate cancer.

Abstract
Ischemic stroke is amongst the leading causes of death and disabilities. The available treatments are suitable for only a fraction of patients and thus novel therapies are urgently needed. Blockage of one of the cerebral arteries leads to massive and persisting inflammatory reaction contributing to the nearby neuronal damage. Targeting the detrimental pathways of neuroinflammation has been suggested to be beneficial in conditions of ischemic stroke. Nuclear receptor 4A-family (NR4A) member Nurr1 has been shown to be a potent modulator of harmful inflammatory reactions, yet the role of Nurr1 in cerebral stroke remains unknown. Here we show for the first time that an agonist for the dimeric transcription factor Nurr1/retinoid X receptor (RXR), HX600, reduces microglia expressed proinflammatory mediators and prevents inflammation induced neuronal death in in vitro co-culture model of neurons and microglia. Importantly, HX600 was protective in a mouse model of permanent middle cerebral artery occlusion and alleviated the stroke induced motor deficits. Along with the anti-inflammatory capacity of HX600 in vitro, treatment of ischemic mice with HX600 reduced ischemia induced Iba-1, p38 and TREM2 immunoreactivities, protected endogenous microglia from ischemia induced death and prevented leukocyte infiltration. These anti-inflammatory functions were associated with reduced levels of brain lysophosphatidylcholines (lysoPCs) and acylcarnitines, metabolites related to proinflammatory events. These data demonstrate that HX600 driven Nurr1 activation is beneficial in ischemic stroke and propose that targeting Nurr1 is a novel candidate for conditions involving neuroinflammatory component.

Abstract
BACKGROUND AND AIMS The diagnosis of heart failure (HF) in elderly patients is often difficult, due to overlap of typical signs and symptoms with those of comorbidities. B-type Natriuretic Peptide (BNP) predicts diagnosis and prognosis of HF, but little is known on its predictive role of short-term prognosis when admission diagnosis is other than HF. METHODS AND RESULTS We prospectively recruited 404 consecutive patients (aged≥65 years) hospitalized in the Unit of Internal Medicine, University of Catania, Catania, Italy, with an admission diagnosis other than HF. Clinical examination, laboratory data and BNP were evaluated at the admission. The predictive value of BNP and other variables for in-hospital mortality, thirty-day mortality and three month re-hospitalization was assessed. During hospitalization 48 (12%) patients died; by logistic regression analysis, in-hospital mortality was not predicted by BNP>600 pg/ml (OR = 1.36; CI 95% = 0.60-2.80; p = 0.4), while it was by chronic kidney disease (CKD, p < 0.001), WBC count (p < 0.001), immobilization syndrome (p < 0.008) and age (p = 0.012). After discharge, 54 patients (15%) died within 30 days; in these patients thirty-day mortality was significantly predicted by BNP>600 pg/ml (OR = 2.70; CI 95% = 1.40-5.00; p = 0.001), CKD (p < 0.001), malnutrition (p = 0.029) and age (p = 0.033). Re-hospitalized patients were 97 (32%); three month re-hospitalization was predicted by BNP>600 pg/ml (OR = 12.28; CI 95% = 6.00-24.90; p < 0.001) and anamnestic HF (p = 0.002). CONCLUSIONS Our study shows that BNP>600 pg/ml, CKD, malnutrition and age predict thirty-day mortality after discharge in elderly patients with an admission diagnosis other than HF, while CKD, WBC count, immobilization syndrome and age predict in-hospital mortality. Three-month re-hospitalization was predicted by BNP>600 pg/ml and anamnestic HF.

Abstract
The use of apheretic procedures in pediatric patients has always been restricted by technical difficulties and the low incidence of diseases requiring this kind of treatment. The aim of the present study was to describe the solutions adopted to solve technical difficulties related to priming, vascular access and monitoring and then to evaluate clinical results. Between 1982 and 2000, 51 consecutive children (28 male, 23 female) with a mean age of 4.9 ± 4.8 years (3 months – 14.8 years) and a mean weight of 19.7 ± 12.8 kg (5 – 52 kg), with renal and/or extra-renal diseases requiring apheretic procedures were selected for the study. The overall number of procedures performed were: 226 plasma-exchange (PE), 6 LDL-apheresis (LDL-A) and 8 protein A immunoadsorption (IAPA) sessions. Our therapeutic protocol involves hematic flux of 20 – 100 ml/min and ultrafiltration of 5–20 ml/min. In each 70–95 minute session we exchanged plasmatic volume with fresh frozen plasma or with a solution of 6% albumin in lactated Ringer's, using heparin (10–20 UI/kg/h). We used Paired Filtration Dialysis Monitor in PE and LDL-A; Citem 10 in IAPA. As plasma separator, we used a filter made of polypropylene, 0.2 m2 surface, 30 ml priming (Hemaplex BT 900). Hemolytic uremic syndrome was the most commonly treated disease (18/51 cases) with good results in 10/18 cases. We recorded, good results in vasculitis as well, in one girl with focal glomerulosclerosis in transplanted kidney and rapid improvement in all children with Guillaine-Barré Syndrome. PE treatment was effective in metabolic disorders such as tirosynemia and familiar hypercolesterolemia. Only 4/12 patients with acute liver failure due to viral hepatitis recovered. We had poor results in the remaining eight cases. Complications were rare and no viral infection was found in any patient. Our data show that it is possible to use these procedures in pediatric patients even though clinical indications and real effectiveness still need to be cleared up.

Growth hormone treatment improves final height and nutritional status of children with chronic kidney disease and growth deceleration. J Endocrinol Invest 2018; 41:325-331. [PMID: 28819753 DOI: 10.1007/s40618-017-0745-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2017] [Accepted: 08/08/2017] [Indexed: 12/19/2022]
Abstract
PURPOSE Growth retardation is a common complication of chronic kidney disease (CKD) in children. Treatment with recombinant human growth hormone (rhGH) has been used to help short children with CKD to attain a height more in keeping with their age group, but the scientific evidence regarding the effect of rhGH on final height is scarce. METHODS Final heights of children with CKD receiving rhGH treatment (cases) were compared with final heights of a matched cohort of children with CKD that did not receive rhGH therapy (controls). RESULTS Sixty-eight rhGH-treated cases (44 boys) were compared with 92 untreated controls (60 boys). Mean duration of rhGH therapy was 4.2 ± 0.9 years; rhGH dose was 0.3 ± 0.07 mg/kg/week. Height SDS at baseline was lower in rhGH-treated patients than in controls (-2.00 ± 1.02 versus -0.96 ± 1.11, p < 0.001). Baseline height SDS was significantly lower than target height SDS in both groups. Height SDS significantly improved from baseline to final height attainment in rhGH-treated patients, while it slightly decreased in controls (mean SDS variation 0.69 ± 1.05 in rhGH-treated cases versus -0.15 ± 1.2 in controls). Final height SDS was -1.25 ± 1.06 in rhGH-treated cases and -1.06 ± 1.17 in controls (p = 0.29). Target adjusted final height SDS was -0.91 ± 1.03 in rhGH-treated cases and -0.61 ± 1.17 in controls (p = 0.1). CONCLUSIONS Long-term rhGH therapy is able to reduce the linear growth deceleration of children with CKD, and ultimately to improve their final height, reducing the difference with target height.

Abstract
BACKGROUND Array-comparative genomic hybridization (array-CGH) is a widely used technique to detect copy number variants (CNVs) associated with developmental delay/intellectual disability (DD/ID). AIMS Identification of genomic disorders in DD/ID. MATERIALS AND METHODS We performed a comprehensive array-CGH investigation of 1,015 consecutive cases with DD/ID and combined literature mining, genetic evidence, evolutionary constraint scores, and functional information in order to assess the pathogenicity of the CNVs. RESULTS We identified non-benign CNVs in 29% of patients. Amongst the pathogenic variants (11%), detected with a yield consistent with the literature, we found rare genomic disorders and CNVs spanning known disease genes. We further identified and discussed 51 cases with likely pathogenic CNVs spanning novel candidate genes, including genes encoding synaptic components and/or proteins involved in corticogenesis. Additionally, we identified two deletions spanning potential Topological Associated Domain (TAD) boundaries probably affecting the regulatory landscape. DISCUSSION AND CONCLUSION We show how phenotypic and genetic analyses of array-CGH data allow unraveling complex cases, identifying rare disease genes, and revealing unexpected position effects.

Abstract
Rodent striatal cells were immortalized using the A58 temperature-sensitive allele of the SV40 large T antigen. Seventy-eight clones and 10 mixed cultures were characterized at the nonpermissive and permissive temperatures. Based on morphology and expression of proteins, cells were classified into three primary types, with types b and c expressing some neuronal characteristics. Type a cells have an epithelial-like morphology with coarse cytoplasmic extensions and occasional fine processes. These cells express vimentin, do not grow well under serum-free conditions and, when confluent, form a uniform monolayer. Type b cells have a polygonal shape and usually extend multiple thin processes. These cells possess large nuclei with multiple nucleoli and do not express vimentin. Type c cells have a fibroblast-like appearance, are unipolar or multipolar, and their soma is smaller than that of type b cells. Type c cells do not express vimentin, and when confluent form a uniform monolayer. Some type b and c clones express NCAM and MAP-2. Several type b and c cell lines were found to consistently express glutamic acid decarboxylase (GAD) immunoreactivity under several tissue culture conditions. Selected cell lines were transplanted into the intact adult rat brain in several locations. Cells survived well for 15 wk and did not form tumors. The proteins expressed in vivo were similar to those expressed in vitro.
