IntroductionCervical intraepithelial neoplasia grade 2 (CIN2) represents a spectrum of lesions with variable progression and regression. Pathological diagnosis of CIN2 is subjective and poorly reproducible. Accurate diagnosis and identification of different patterns of CIN2 related to outcome are essential to reduce the risks of overtreatment or undertreatment. It is important to explore novel methods for risk stratification of CIN2 to enable targeted treatment of women at high risk of progression or persistent disease and follow-up of women at low risk. The combination of the novel biomarker human papillomavirus (HPV) E4 with p16INK4a targets steps in the transition from a productive oncogenic HPV infection (CIN1) to a transformed lesion (CIN3) within CIN2. Previous cross-sectional studies suggest that HPV E4 combined with p16INK4a may be valuable for risk assessment of CIN2. However, data on HPV E4/p16INK4a as a predictor for CIN2 regression is lacking.Methods and analysisWe will conduct a historical cohort study including 500 women aged 23–40 years with a first CIN2 diagnosis in Aarhus, Denmark during 2000–2010. Women will be eligible if they have undergone active surveillance and have no previous record of hysterectomy, cone biopsy, and CIN2 or worse. Women will be randomly selected through the Danish Pathology Databank. Tissue samples from women included will be sectioned for p16INK4a and HPV E4 immunohistochemical staining in addition to conventional hematoxylin and eosin (H&E) staining. A positive result will be defined as HPV E4 positive. Through the Danish Pathology Databank, we will collect results on all subsequent cervical biopsies. Regression will be used as the primary outcome.Ethics and disseminationThe study has been approved by the Ethical Committee in Central Denmark Region (1-10-72-60-20) and registered at the Faculty of Health, Aarhus University. Results will be published in a peer-reviewed journal and presented at scientific meetings.Trial registration numberNCT05049252.

ObjectiveTo assess the impact of iterative changes in preoperative and postoperative biopsy techniques on the outcomes of men undergoing the precision prostatectomy procedure. Precision prostatectomy is a novel surgical treatment for prostate cancer that aims to maximally preserve erectogenic nerves via partial preservation of the prostate capsule.DesignRetrospective.SettingSingle tertiary care center.ParticipantsThis study included 120 patients who consented to undergo prostate cancer treatment with the precision prostatectomy procedure. Patients were originally enrolled in one of two separate prospective protocols studying precision prostatectomy.InterventionsPreoperatively, 60 patients were screened with transrectal (TR) biopsy and 60 were screened by transperineal (TP) biopsy. Ultimately, 117 patients underwent precision prostatectomy. Of the 43 postoperative biopsies, 19 were TR; 17 were TP with ultrasound; and 7 were TP with microultrasound (mUS).Main outcome measuresPreoperatively, we evaluated whether the transition to TP biopsy was associated with differences in postoperative treatment failure defined as a neoplasm-positive postoperative biopsy. Postoperative biopsies were compared with respect to their ability to sample the remnant tissue, specifically percentage of cores positive for prostate tissue.ResultsPreoperatively, 9/60 (15%) positive postoperative biopsies occurred in the TR group and 6/60 (10%) in the TP group; Kaplan-Meier survival estimates did not differ between groups (p=0.69 by log rank). Postoperatively, the numbers of cores positive for prostate tissue were 99/160 (62%), 63/107 (59%), and 36/39 (92%) in the TR biopsy, TP with ultrasound, and TP with mUS groups, respectively; this difference was statistically significant versus the rate in the TR and standard TP groups (p=0.0003 and 0.0002).ConclusionWe found no significant improvement in patient screening, preoperatively—though limited by small sample size and relatively short follow-up. The incorporation of high-frequency mUS for postoperative biopsies improved the ability to sample the remnant tissue with a higher efficiency.

BackgroundPancreatic ductal adenocarcinoma (PDAC) is a highly lethal malignancy in need of effective (immuno)therapeutic treatment strategies. For the optimal application and development of cancer immunotherapies, a comprehensive understanding of local and systemic immune profiles in patients with PDAC is required. Here, our goal was to decipher the interplay between local and systemic immune profiles in treatment-naïve patients with PDAC.MethodsThe immune composition of PDAC, matched non-malignant pancreatic tissue, regional lymph nodes, spleen, portal vein blood, and peripheral blood samples (collected before and after surgery) from 11 patients with PDAC was assessed by measuring 41 immune cell markers by single-cell mass cytometry. Furthermore, the activation potential of tumor-infiltrating lymphocytes as determined by their ability to produce cytokines was investigated by flow cytometry. In addition, the spatial localization of tumor-infiltrating innate lymphocytes in the tumor microenvironment was confirmed by multispectral immunofluorescence.ResultsWe found that CD103+CD8+T cells with cytotoxic potential are infrequent in the PDAC immune microenvironment and lack the expression of activation markers and checkpoint blockade molecule programmed cell death protein-1 (PD-1). In contrast, PDAC tissues showed a remarkable increased relative frequency of B cells and regulatory T cells as compared with non-malignant pancreatic tissues. Besides, a previously unappreciated innate lymphocyte cell (ILC) population (CD127–CD103+CD39+CD45RO+ILC1-like) was discovered in PDAC tissues. Strikingly, the increased relative frequency of B cells and regulatory T cells in pancreatic cancer samples was reflected in matched portal vein blood samples but not in peripheral blood, suggesting a regional enrichment of immune cells that infiltrate the PDAC microenvironment. After surgery, decreased frequencies of myeloid dendritic cells were found in peripheral blood.ConclusionsOur work demonstrates an immunosuppressive landscape in PDAC tissues, generally deprived of cytotoxic T cells and enriched in regulatory T cells and B cells. The antitumor potential of ILC1-like cells in PDAC may be exploited in a therapeutic setting. Importantly, immune profiles detected in blood isolated from the portal vein reflected the immune cell composition of the PDAC microenvironment, suggesting that this anatomical location could be a source of tumor-associated immune cell subsets.
Calibration of a large-size wide-range neutron spectrometer
Authors: Cirillo Andrea , Caresana Marco 
Published: July 2022

AbstractOver the last year, Politecnico di Milano has developed the W-PIE, a cosmic neutron spectrometer employed for environmental measurements. The W-PIE is based on the Artkis M800 thermal neutron detector and works as a 4-channel spectrometer for detecting neutrons in the energy range 0.01eV – 1GeV. In this paper, the calibration of the instrument in monoenergetic neutron fields at the PIAF facility of PTB is discussed. These measurements were intended to calibrate the detector and validate the response functions. Despite obtaining satisfactory results in terms of fluence and dose calculations, the irradiation in the monoenergetic fields suggested that the detector sensitivity to fast neutrons was greater than expected by the calculated response functions. This discrepancy was investigated and a reasonable explanation for it was proposed.
Neuronal Alterations in Secondary Thalamic Degeneration Due to Cerebral Infarction: A
11
C-Flumazenil Positron Emission Tomography Study
Authors: Yamauchi Hiroshi , Kagawa Shinya , Kusano Kuninori , Ito Miki , Okuyama Chio 
Published: July 2022

Background:
Studies using animal experiments have shown secondary neuronal degeneration in the thalamus after cerebral infarction. Neuroimaging studies in humans have revealed changes in imaging parameters in the thalamus, remote to the infarction. However, few studies have directly demonstrated neuronal changes in the thalamus in vivo. The purpose of this study was to determine whether secondary thalamic neuronal damage may manifest as a decrease in central benzodiazepine receptors in patients with cerebral infarction and internal carotid artery or middle cerebral artery disease.

Methods:

We retrospectively analyzed the data of 140 patients with unilateral cerebral infarction ipsilateral to internal carotid artery or middle cerebral artery disease. All patients had quantitative measurements of

C-flumazenil binding potential (FMZ-BP), cerebral blood flow, and cerebral metabolic rate of oxygen using positron emission tomography in the chronic stage. Region of interest analysis was performed using NeuroFlexer—an automated region of interest analysis software using NEUROSTAT.

Results:
In the thalamus ipsilateral to the infarcts, the values of FMZ-BP, cerebral blood flow, and cerebral metabolic rate of oxygen were significantly lower than those in the contralateral thalamus. Significant correlations were found between the ipsilateral-to-contralateral ratio of FMZ-BP and the ipsilateral-to-contralateral ratio of cerebral blood flow or cerebral metabolic rate of oxygen in the thalamus. Patients with corona radiata infarcts and striatocapsular infarcts had significantly decreased ipsilateral-to-contralateral FMZ-BP ratio in the thalamus compared with those without. The ipsilateral-to-contralateral ratio of FMZ-BP in the thalamus was significantly correlated with the ipsilateral-to-contralateral cerebral metabolic rate of oxygen ratio in the frontal cortex and showed a significant negative correlation with the number of perseverative errors on the Wisconsin Card Sorting Test.

Conclusions:
Secondary thalamic neuronal damage may manifest as a decrease in central benzodiazepine receptors in patients with cerebral infarction and internal carotid artery or middle cerebral artery disease, which may be associated with frontal lobe dysfunction.
Are link-based and citation-based journal metrics correlated? An Open Access megapublisher case study
Authors: Orduña-Malea Enrique , Aguillo Isidro F. 
Published: July 2022

Abstract
The current value of link counts as supplementary measures of the formal quality and impact of journals is analyzed, considering an open access megapublisher (MDPI) as a case study. We analyzed 352 journals through 21 citation-based and link-based journal-level indicators, using Scopus (523,935 publications) and Majestic (567,900 links) as data sources. Given the statistically significant strong positive Spearman correlations achieved, it is concluded that link-based indicators mainly reflect the quality (indexed in Scopus), size (publication output), and impact (citations received) of MDPI’s journals. In addition, link data are significantly greater for those MDPI journals covering many subjects (generalist journals). However, nonstatistically significant differences are found between subject categories, which can be partially attributed to the “series title profile” effect of MDPI. Further research is necessary to test whether link-based indicators can be used as informative measures of journals’ current research impact beyond the specific characteristics of MDPI.
Catalog of Hymenoptera described by Giovanni Gribodo (1846–1924) (Insecta)
Authors: PENATI FABIO , MARIOTTI ALBERTO 
Published: July 2022

Giovanni Gribodo (1846–1924) was an Italian civil engineer who described 377 new taxa of Hymenoptera, 199 of which are still valid and in use today, and proposed 6 replacement names. The present catalog provides a brief biography of Gribodo, a bibliography of his 42 publications and a complete list of the taxa proposed by Gribodo. The catalog lists, for all published names, details on the type series, type locality and collector, present status based on literature, all data labels, relevant references and remarks. A gazetteer of type-localities, a systematical list of Genus- and Species-group names, a chronological list of new names proposed by Giovanni Gribodo, with name-bearing types, and a list of Algerian species and varieties are also given. Furthermore, an unpublished manuscript by Gribodo on hymenopterological fauna of Tunisia, still kept at the Civic Museum of Natural History “Giacomo Doria” (Genoa, Italy), is described, and data on the 57 “new” taxa therein listed are reported, discussing their relevance in order to ascertain the original type series of 27 taxa validly published later. Finally, the problem posed by the enigmatic “disappearance” of a large number of Algerian types, already faced by several entomologists in the past, is analyzed, in order to prevent future mistaken designations of lectotypes and neotypes. The following six nomenclatural acts are proposed here by R. Wahis: Hemipepsis sycophanta Gribodo, 1884 = Hemipepsis bellicosa (Smith, 1873) new synonym; Anospilus sulcithorax (Gribodo, 1924) new combination; Auplopus validus (Gribodo, 1884) new combination; Dichragenia quartinae (Gribodo, 1884) new combination; Diplonyx caesar (Gribobo, 1894) new combination; Paracyphononyx melanicrus Gribodo, 1884 status revalidated (resurrected from synonymy with Pompilus ruficrus Klug, 1834). The following four nomenclatural acts are proposed by F. Penati: Parachrysis Gribodo, 1879 [subgenus of Chrysis Linnaeus] = Chrysis Linnaeus, 1760 new synonym; Psammotherma (Mutilla) quartinae Gribodo, 1884 = Psammotherma flabellata (Fabricius, 1804) new synonym; Megascolia (Regiscolia) alecto (Smith, 1858) subspecies vespillo (Gribodo, 1893) new combination; Megachile (Megachile) moutoni Gribodo, 1894 emendated name.

Published: July 2022

Petroleum-based polymers have a wide range of uses in the packaging industry, including films, food packaging, rigid containers, foamed containers, medical products, etc. This study focuses on improving the properties of polyvinyl alcohol (PVA) based material systems, one of the most popular water-soluble biopolymers, to reduce the waste of petroleum-based plastics, which are widely used. Polyvinyl alcohol (PVA) nanocomposite films containing low concentrations (0.05–1%) of graphene oxide (GO) and reduced graphene oxide (rGO) were produced via the solution casting method. When electrical properties of nanocomposite films were evaluated, the addition of 1 wt% GO and rGO resulted in a 36% and 45% decrease in the volumetric resistance of the films as well as a decrease in surface resistance of 24.5% and 34.9%, respectively. The maximum tensile strength of 1% GO and rGO-reinforced PVA nanocomposites was found to be ∼59 MPa and ∼68 MPa with an increase of 20% and 38% compared to neat PVA films, respectively. The average Young’s modulus of 1% GO and rGO-reinforced PVA nanocomposites also increased from 2561 MPa to 3515 MPa and 4219 MPa with an increase of 37% and 65%, respectively. As a result, the electrical conductivity, Young’s modulus, maximum tensile strength, thermal properties, and optical absorption of nanocomposite films increased by adding GO and rGO to PVA. The results show that the produced nanocomposite film may be a promising material for packaging applications.

Published: July 2022

Background For transplant-eligible newly diagnosed multiple myeloma patients, autologous hematopoietic stem cell transplant followed by maintenance lenalidomide is a standard of care practice. Maintenance lenalidomide dosing practices vary amongst physicians and current literature lacks comparisons on intermittent versus continuous dosing. In this retrospective study, we compared the safety, tolerability, and efficacy of continuous versus intermittent lenalidomide dosing. Methods This single-center, retrospective review included 72 patients with multiple myeloma receiving lenalidomide maintenance between 2018 and 2021. The primary objective was to determine the incidence of dose modification, defined as any dosage reduction, delay in treatment, or discontinuation of therapy. The secondary objectives were to determine the incidence of hematological and non-hematological toxicities between the two groups. Results A total of 58 patients in the continuous group and 14 patients in the intermittent group were included. Fifty-four percent of patients in the continuous group required dose modification versus 30% in the intermittent group. Patients who received continuous dosing appeared to have a higher incidence of adverse events when compared to intermittent dosing with the most common adverse events being neutropenia, fatigue, and rash. Twenty-four patients in the continuous group switched to an intermittent schedule after an adverse event. Of these patients, only 8% required further dose modification. Conclusion The higher incidence of lenalidomide dose modifications in the continuous arm suggests that a majority of patients are not able to tolerate continuous lenalidomide maintenance. A more tolerable option for maintenance may be an intermittent schedule, as reflected by the favorable safety outcomes in this group.

Objectives Tumors involving the anterior portion of the maxillary sinus remain technically challenging to access via an endoscopic approach. The modified endoscopic Denker's (MED) procedure was recently introduced to address such lesions. We present a multicenter series of 58 patients with tumors involving the anterior maxillary sinus successfully resected using a MED procedure and present the clinical outcomes and complications. Methods A multi-institution retrospective chart review was performed on patients who underwent the MED approach for the management of tumors involving the anterior maxillary sinus from 2009 to 2020. Demographic data, pathology, surgical outcomes, and complications were reviewed. Results Fifty-eight patients were identified, including 34 (58.6%) male and 24 (41.4%) female patients. The most common pathologies included: inverted papilloma (n = 27; 46.6%), adenoid cystic carcinoma (n = 9; 15.5%), and squamous cell carcinoma (n = 8; 13.8%). Thirty-eight patients (65.5%) underwent MED alone, while 20 (34.5%) had combined expanded endonasal approaches for lesions extending beyond the maxillary sinus. All maxillary sinus lesions were successfully accessed with the MED procedure without the need for an additional approach. After a mean follow-up of 30 months (range, 1–127), 8 of 58 (13.8%) patients developed complications related to the MED, including epiphora requiring an additional procedure (n = 4; 6.9%), prolonged facial/palatal numbness (n = 3; 5.2%), severe epistaxis (n = 1; 1.7%), and vestibular stenosis (n = 1; 1.7%), the latter of which occurred following postoperative radiation. Conclusion The MED procedure is a safe and highly effective approach for benign and malignant tumors involving the anterior maxillary sinus. However, patients should be counseled preoperatively on potential complications including the risk of facial numbness and epiphora.

Published: July 2022

Background: The evidence for safe and effective interventions to treat the negative and cognitive symptoms of schizophrenia is lacking. Objectives: Vortioxetine is a novel antidepressant that has been used as adjunctive therapy for the treatment of psychosis; however, its effectiveness in clinical practice is relatively unknown. In this study, we aimed to determine the potential clinical effectiveness and safety and tolerability of vortioxetine in psychosis. Design: This is a non-interventional, retrospective study on the add-on use of vortioxetine in a group of people with schizophrenia-spectrum disorders in a large UK NHS mental health trust. Methods: Clinical effectiveness of vortioxetine was retrospectively assessed through the Clinical Global Impression – Severity (CGI-S) scale at 3 months. Safety and tolerability were evaluated through treatment discontinuation rates at 3, 6, and 12 months, and clinical reasons were evaluated at the primary endpoint of 3 months. Results: Data were available for 40 subjects with a diagnosis of schizophrenia or schizoaffective disorder–prescribed vortioxetine treatment; 30 (75%) remained on treatment at 3 months. At CGI-S assessment, 15 of the 35 evaluated subjects reported at least a 1-point improvement, from 5 at baseline to 4 after 3 months of treatment. Twenty-six (65%) remained on treatment at 1-year follow-up. The main reasons for those discontinuing treatment were inadequate response (10%) and manic switch (7.5%), while one subject refused treatment. Tolerability to treatment was good, and 36 subjects (90%) reported no adverse events specific to vortioxetine treatment. Conclusion: Schizophrenia is a complex illness, and there is insufficient treatment response in many individuals. A significant proportion of whom may require adjunctive treatments depending on the nature of the residual symptoms. Vortioxetine could be a potentially safe and effective option in such people, but further controlled studies are required.
