Genomic Epidemiology of SARS-CoV-2 in Large University Hospital Cohort: The UnCoVER-Brazil Project

This work aimed to study the role of different SARS-CoV-2 lineages in the epidemiology of multiple waves of the COVID-19 pandemic in Ribeirão Preto (São Paulo state), with comparison within Brazil and globally. Viral genomic sequencing was combined with clinical and sociodemographic information of 2,379 subjects at a large Brazilian hospital. On the whole 2,395 complete SARS-CoV-2 genomes were obtained from April 2020 to January 2022. We report variants of concern (VOC) and interest (VOI) dynamics and the role of Brazilian lineages. We identified three World Health Organization VOCs (Gamma, Delta, Omicron) and one VOI (Zeta), which caused distinct waves in this cohort. We also identified 47 distinct Pango lineages. Consistent with the high prevalence of Gamma in Brazil, Pango lineage P.1 dominated infections in this cohort for half of 2021. Each wave of infection largely consisted of a single variant group, with each new group quickly and completely rising to dominance. Despite increasing vaccination in Brazil starting in 2021, this pattern was observed throughout the study and is consistent with the hypothesis that herd immunity tends to be SARS-CoV-2 variant-specific and does not broadly protect against COVID-19.

Immunomodulatory effects of metronomic vinorelbine (mVRL), with or without metronomic capecitabine (mCAPE), in hormone receptor positive (HR+)/HER2-negative metastatic breast cancer (MBC) patients: final results of the exploratory phase 2 Victor-5 study

Tregs are able of suppressing tumor-specific effector cells, such as lymphocytes CD8+, CD4+ and Natural Killer cells. Different drugs, especially different schedules of administration, like metronomic chemotherapy (mCHT), seem to be able to increase anticancer immunity, by acting on downregulation of Tregs. Most of the data available regarding the immunomodulating effect of mCHT have been obtained with Cyclophosphamide (CTX). Aim of the present study was to explore the effects of mVRL and mCAPE administration, alone or in combination, on T cells. Observation of 13 metastatic breast cancer patients lasted controlling for 56 days, where Treg frequencies and function, spontaneous anti-tumor T-cell responses were monitored, as well as the clinical outcome. No depletion in Treg absolute numbers, or percentage of T lymphocytes, was observed. Only in 5 patients, a modest and transient depletion of Tregs was observed during the first 14 days of treatment. To better describe the effect on Tregs, we subsequently looked at the variations in Memory, Naïve and Activated Treg subpopulations: we observed a trend in reduction for memory Treg (Treg MEM) and an increase for Treg Naïve (Treg NAIVE) and Treg Activated (Treg ACT) components. We finally analyzed the average trend of Treg in the Treg depleted patients and non-depleted ones, without fiding any significant differences. The trend of the Treg MEM appeared different, showing a reduction during the first 14 days, followed by an increase at the levels before treatment at Day 56 in the group of depleted patients and a progressive substantial reduction in the group of non-depleted patients along the entire course of treatment. Opposed to the data known, treatment with mVRL w/o mCAPE did not show any effect on Tregs.

Atypical Prolonged Viral Shedding With Intra-Host SARS-CoV-2 Evolution in a Mildly Affected Symptomatic Patient

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is caused by a respiratory virus with a wide range of manifestations, varying from asymptomatic to fatal cases, with a generally short outcome. However, some individuals present long-term viral shedding. We monitored 38 individuals who were mildly affected by the SARS-CoV-2 infection. Out of the total studied population, three (7.9%) showed atypical events regarding the duration of positivity for viral RNA detection. In one of these atypical cases, a previously HIV-positive male patient presented a SARS-CoV-2 RNA shedding and subgenomic RNA (sgRNA) detected from the upper respiratory tract, respectively, for 232 and 224 days after the onset of the symptoms. The SARS-CoV-2 B.1.1.28 lineage, one of the most prevalent in Brazil in 2020, was identified in this patient in three serial samples. Interestingly, the genomic analyses performed throughout the infectious process showed an increase in the genetic diversity of the B.1.1.28 lineage within the host itself, with viral clearance occurring naturally, without any intervention measures to control the infection. Contrasting widely spread current knowledge, our results indicate that potentially infectious SARS-CoV-2 virus might be shed by much longer periods by some infected patients. This data call attention to better adapted non-pharmacological measures and clinical discharge of patients aiming at preventing the spread of SARS-CoV-2 to the population.

Paraphyly and evolutionary independent lineages in Gymnotus pantherinus (Gymnotiformes: Gymnotidae) in the Brazilian Atlantic Forest Coastal Streams

In the Brazilian Atlantic Forest (AF), many terrestrial species with broad geographical distributions show high diversity and endemism of intraspecific lineages, as revealed by molecular genetic data. This pattern, however, is less explored in freshwater fishes. Gymnotus pantherinus is an electric fish endemic to the Brazilian coastal drainages that shows a wide distribution, ranging from the states of Bahia to Santa Catarina, an unusual pattern for AF fishes. It has been hypothesized that G. pantherinus is a species complex because distinct morphotypes were described for the species based on morphometric and meristic features. We used mitochondrial and nuclear data to test this hypothesis. Based on phylogenetic inference and multi-locus, multispecies coalescent methods, we identified six independent lineages, flagging them as candidate species. One such lineage is the recently described species G. refugio that is nested within G. pantherinus and renders it paraphyletic, showing it is a species complex. We named G. pantherinus stricto sensu the lineage that includes samples from the type locality (Santos, SP). Our results show that genetic lineages correspond only partially and far exceed the number of previously reported morphotypes. Genetic breaks in the group correspond to landscape features associated with the Serra do Mar mountain range and with riverine dynamics caused by sea level changes during the last glacial maximum. Moreover, we found evidence of river capture events affecting phylogeographic structure in the group. We uncovered an important dimension of diversity in the group and encourage further integration of genetic and phenotypic data. Such integration is a fruitful approach not only to reduce the gap between taxonomy and evolutionary history in Gymnotidae, but also to uncover the real AF biodiversity.

Species diversity and biogeography of an ancient frog clade from the Guiana Shield (Anura: Microhylidae: Adelastes, Otophryne, Synapturanus) exhibiting spectacular phenotypic diversification

The outstanding biodiversity of the Guiana Shield has raised many questions about its origins and evolution. Frogs of the genera Adelastes, Otophryne and Synapturanus form an ancient lineage distributed mostly across this region. These genera display strikingly disparate morphologies and life-history traits. Notably, Synapturanus is conspicuously adapted to fossoriality and is the only genus within this group to have dispersed further into Amazonia. Moreover, morphological differences among Synapturanus species suggest different degrees of fossoriality that might be linked to their biogeographical history. Through integrative analysis of genetic, morphometric and acoustic data, we delimited 25 species in this clade, representing a fourfold increase. We found that the entire clade started to diversify ~55 Mya and Synapturanus ~30 Mya. Members of this genus probably dispersed three times out of the Guiana Shield both before and after the Pebas system, a wetland ecosystem occupying most of Western Amazonia during the Miocene. Using a three-dimensional osteological dataset, we characterized a high morphological disparity across the three genera. Within Synapturanus, we further characterized distinct phenotypes that emerged concomitantly with dispersals during the Miocene and possibly represent adaptations to different habitats, such as soils with different physical properties.

Procalcitonin is useful in driving the choice of early antibiotic treatment in patients with bloodstream infections

OBJECTIVE

To evaluate whether PCT levels could be used to distinguish among different bacterial and fungal etiologies in patients with documented bloodstream infection (BSI).

PATIENTS AND METHODS

Monocentric retrospective cohort study on patients admitted to the Fondazione Policlinico Gemelli Hospital between December 2012 and November 2015 with BSI. Those who had undergone PCT determination within 48 hours of when the first positive blood culture was sampled were included in the study.

RESULTS

Four hundred and one patients were included in the study. Both the 24h and 48h PCT values were significantly higher in patients with Gram-negative (GN) BSI than in those with Gram-positive (GP) or candida BSI (p at ANOVA = 0.003). A PCT value of > 1 ng/ml was found in 31.5% of patients with GN BSI. Less than 7% of people with candida BSI had PCT level of > 1 ng/ml. At multivariable regression analysis, GN BSI, septic shock, and plasma creatinine were significantly correlated with PCT values.

CONCLUSIONS

PCT may be of value in distinguishing GN BSI from GP, and fungal BSI and PCT values of > 1 ng/ml could be used to prevent unnecessary antifungal treatment.

A false positive case of high-sensitivity cardiac troponin in a patient with acute chest pain: Analytical study of the interference

We report a case of a heterophile antibodies interference in a new high-sensitivity troponin commercial immunoassay (cTNIH Siemens), observed in a patient with possible acute coronary syndrome (ACS). The analytical interference was investigated with standard laboratories procedures. The false positive result was found with different troponin methods and kits. We also investigated the protein sequence of cTnl and no sequence variants were detected. The discordance between clinical pictures and high concentration of cTnl, together with the collaboration between clinicians and laboratory staff avoided possible erroneous diagnosis and further invasive investigations to the patient.

Advanced capabilities for materials modelling with Quantum ESPRESSO

Quantum EXPRESSO is an integrated suite of open-source computer codes for quantum simulations of materials using state-of-the-art electronic-structure techniques, based on density-functional theory, density-functional perturbation theory, and many-body perturbation theory, within the plane-wave pseudopotential and projector-augmented-wave approaches. Quantum EXPRESSO owes its popularity to the wide variety of properties and processes it allows to simulate, to its performance on an increasingly broad array of hardware architectures, and to a community of researchers that rely on its capabilities as a core open-source development platform to implement their ideas. In this paper we describe recent extensions and improvements, covering new methodologies and property calculators, improved parallelization, code modularization, and extended interoperability both within the distribution and with external software.

Unconventional side effects of antidepressants: Focus on emotional blunting

Objectives

The aim of this study was to investigate the unconventional side-effects of selective serotonin reuptake inhibitors (SSRIs) and tricyclics (TCAs) antidepressants during long-term treatment of depression, with a special focus on emotional blunting and, in particular, on the possible changes of some features of loving relationships.

Methods

Two hundred outpatients (130 women and 70 men, mean age ± SD: 43.4 ± 11.1 years) were enrolled. They were suffering from mild or moderate depression, according to DSM–5 criteria, treated with one antidepressant for at least six months and involved in a long-term loving relationship. A specifically designed test, the so-called “sex, attachment, love” (SALT) questionnaire was built to assess the possible changes of the loving relationship.

Results

The results showed differences between the two genders, in particular women taking TCAs reported more sexual side effects than men, whereas men taking SSRIs complained a reduction of the feelings of love and attachment towards the partner.

Conclusions

Antidepressants seem to have a dimorphic effect on some elements of loving relationships, however these results need to be further explored.

Impulsivity and pathological gambling: An Italian study

Introduction

Pathological gambling (PG) is a behavioral addictive disorder characterized by persistent and problematic gambling behaviors, in presence of impairment of self-regulation and impulsivity. Impulsivity is widely supported by literature in developing and maintaining addictive behaviors and PG.

Aim(s)

The aim of this study is to compare PG to impulsivity in a group of Italian outpatients, in order to further explore their appealing relation and to sensitize local public institutions about this problem that is of growing concern amongst our population.

Methods

Fifty outpatients were recruited at the psychiatric outpatient ward of the University of Pisa. All of them had a diagnosis of PG, assessed throughout the structured clinical interview for DSM-5 (SCID-5). The sample was compared with a similar group of healthy control subjects. South Oaks Gambling Screen (SOGS) scale and Barrat Impulsivity Scale (BIS-11) questionnaires were used to assess respectively the severity of PG and impulsivity traits of personality.

Results

PG patients reported significantly higher total score in BIS-11 than control subjects. In particular, the “motor impulsivity” and “cognitive complexity” scores were significantly higher in PG patients, as well as “motor” and “non-planning” impulsivity subscale scores. A positive and significant correlation was found between BIS-11 and SOGS total scores.

Conclusions

These results corroborate the existence of the widely described association between impulsivity and PG. Also they support the notion that impulsivity may represent a core element of PG and, perhaps, to a typical personality trait, that may be particularly related to the development of addictive and impulsive behaviors.

Abstract P2-04-05: Immunomodulation effects of metronomic oral Vinorelbine (mVRL), with or without capecitabine (CAPE), on Treg levels in advanced breast cancer (ABC) patients (pts). Preliminary results of the VICTOR-5 study

BACKGROUND

In cancer patients, the accumulation of Tregs is associated with tumor progression and the suppression of anti-tumor immune response. Metronomic cyclophosphamide (mCTX) induces a profound and selective reduction of circulating Tregs, whereas no data are available regarding a possible effect on immune system. In the present analysis, we report preliminary data of Treg frequencies and function during a period of treatment of 2 months and correlations with anti-tumour T-cell response, in a group of HR+/HER2ve ABC pts.

PATIENTS AND METHODS

Following approval by the Ethical Committee, a sample of 3 ml of peripheral blood was drawn from 12 ABC pts for which mVRL 40- 50 mg thrice a week (N=10), ± mCAPE 1500 mg/day (N=2), was indicated. Median age was 66,5 years (45-86); 2/ 12 received the mCHT as 1st-line therapy, 10/12 as 2nd-line or further. Blood samples were collected at baseline (T0) and after 14 (T1), 28 (T2), 42 (T3) and 56 days (T4) of treatment. Total lymphocytes (TL) and lymphocyte subgroups were determined according to NaacK et Al guide lines. The Treg subpopulations have been identified by monoclonal antibodies CD45 V500, CD3 V450, CD4 PerCP-Cy5.5, CD25 PE, CCR4 PE-Cy7, CD 27 Alexa 647, CD45RO APC-H7, CD28 FITC, (BD Biosciences, San Jose, CA) and analyzed with BD FACS CantoTM II (Becton Dickinson, San Jose, CA), technic Lyse/Wash and software FACSDivaTM.

RESULTS

Data for the purpose of this analysis are available for 10 out of 12 enrolled pts. mVRL ± mCAPE induced a significant reduction of circulating Treg in 6/10 pts (60%) – Group A - at day 14. Median percentages of Treg among CD4+ cells were 9.4% ±1.5% SE at baseline vs 6.8% ± 4.5% SE and 7.6% ± 1.2% SE after 14 and 28 days of treatment in Group A. In patients without Treg depletion – Group B – median percentages of Treg were 8.4% ± 0.9% SE, 9.6% ± 1.3%SE and 8.2% ± 1.5%SE as measured at the same time points. The depletion of Treg is associated with a slight expansion of CD8+ cells in Group A at all times of evaluation. No increase in CD8+ population has been observed in Group B. Median percentages of Treg and CD8+ cells in the two Groups are reported in Tables 1 & 2.

CONCLUSION

Our results suggest that mVRL induces different immunomodulation effects in an unselected population of ABC pts. Treg depletion seems to increase the adaptive immune response. Data obtained from a longer follow up will be presented. These findings are hypothesis-generating for future evaluation of mVRL as a priming agent to increase response to anti PDL-1 agents.

Ionizing radiation: brain effects and related neuropsychiatric manifestations

Recently, an increasing interest has been directed towards the investigation of brain effects of ionizing radiation (IR), as it is now evident that, depending on the doses, the damages character and severity, as well as clinical man ifestations are different. They are generally considered to be the result of a blending of atherosclerotic, cardiovas cular, cerebrovascular and neurodegenerative processes. Further, an ongoing debate has been opened on the pos sible brain abnormalities following medical radiation from X ray in interventional radiology and nuclear medicine procedures that would involve both patients and medical workers. The aim of the present paper is to summarize literature data on brain effects of IR exposure, with a special focus on those gathered by some of the authors after the Chornobyl nuclear plant disaster, and how they can be related to the pathophysiology of different neuropsy chiatric disorders.

Role of inflammation in non-allergic rhinitis

OBJECTIVE

To investigate the role of inflammation in non-allergic rhinitis (NAR) patients in a large series to establish the prevalence of different NAR-subtypes, clinical features and the role of nasal cytology in the diagnostic algorithm.

METHODOLOGY

Patients were selected out of 3650 individuals who spontaneously presented at our institution. We consecutively enrolled 519 NAR-patients in an analytical cross-sectional study between November 2007 and June 2013 (level of evidence: 3b). All patients underwent rhinological evaluation including symptoms questionnaire, endoscopy, CT scan, allergy tests and nasal cytology.

RESULTS

The inflammatory cell infiltrate affects the severity of symptoms differently, allowing for identification of different phenotypes of NAR. We distinguished two groups: “NAR without inflammation”(NAR-) and “NAR with inflammation”(NAR+), in addition to different NAR-subtypes with inflammation. A significant difference was observed in terms of clinical symptoms and association with comorbidities (previously diagnosed asthma and aspirin intolerance) between NAR–, NAR+ and between different NAR+ subtypes.

CONCLUSION

Our data suggest that NAR- and NAR with neutrophils behave similarly, showing lower symptom score values and a lower risk of association with comorbidities compared to NAR with eosinophils and mast cells (singularly or mixed). In our belief it is very important to establish the presence and type of inflammation in non-allergic rhinitis patients and nasal cytology is a very useful test in correct differential diagnosis.

The relationship between epilepsy and depression: an update

Several population-based studies and clinical data suggest the presence of strict relationships between epilepsy and depression. The incidence of depressive symptoms in patients with epilepsy is significantly higher than in the general population or in patients with other neurological disorders or chronic diseases, as shown by the majority, albeit not all, findings. Even the rate of suicide is higher in epileptic patients than in the general population. Such observations suggest the existence of common neurobiological substrates involving hyperactivity of the hypothalamus-pituitary-adrenal axis, as well as disturbances of different neurotransmitter systems, particularly serotonin and norepinephrine. The aim of this paper is to review the current literature on the prevalence, clinical manifestations and etiology of depression in epilepsy, with a particular focus on the possible pathophysiological mechanisms shared by the two conditions. In spite of the large amount of data, several questions remain open and further studies are necessary to explore more thoroughly the complex and bidirectional relationships between epilepsy and depression.

Latest advancements in the pharmacological treatment of binge eating disorder

BACKGROUND

Binge-eating disorder (BED) is a relatively new disorder characterized by binge eating without purging.

AIM

The purpose of this article is to review the potential use of the recently proposed compounds for the treatment of BED.

MATERIALS AND METHODS

A medline of published articles from 1980 to December 2012 was carried out using the following keywords: BED and treatment, topiramate, zonisamide, ghrelin.

RESULTS

The pharmacological treatment of BED is still heterogenous and poorly established, mainly for the lack of controlled studies in large samples of patients.

CONCLUSIONS

The data on serotonin and norepinephrine reuptake inhibitors and on novel anticonvulsants seem quite promising in terms of efficacy and tolerability. In addition, the preliminary findings on the possibility of modulating appetite through the interference with the ghrelin system suggest new and intriguing ways of intervention in BED.

Cognitive, psychological and psychiatric effects of ionizing radiation exposure

Radiation exposure leads to an increased risk for cancer and, possibly, additional ill-defined non-cancer risk, including atherosclerotic, cardiovascular, cerebro-vascular and neurodegenerative effects. Studies of brain irradiation in animals and humans provide evidence of apoptosis, neuro-inflammation, loss of oligo-dendrocytes precursors and myelin sheaths, and irreversible damage to the neural stem compartment with long-term impairment of adult neurogenesis. With the present paper we aim to present a comprehensive review on brain effects of radiation exposure, with a special focus on its impact on cognitive processes and psychological functions, as well as on their possible role in the pathophysiology of different psychiatric disorders.

Relaxometric investigations and MRI evaluation of a liposome-loaded pH-responsive gadolinium(III) complex

Accurate measurement of the tissue pH in vivo by MRI may be of clinical value for both diagnosis and selection/monitoring of therapy. To act as pH reporters, MRI contrast agents have to provide responsiveness to pH that does not require prior knowledge of the actual concentration of the contrast agent. This work deals with the use of a paramagnetic gadolinium(III) complex, loaded into liposomes, whose relaxometric properties are affected by the pH of the medium. In this system, the amphiphilic metal complex, which contains a moiety whose protonation changes the coordination properties of the metal chelate, experiences a different intraliposomial distribution depending on the pH conditions. The pH of the solution can be unambiguously identified by exploiting the peculiar characteristics of the resulting NMRD profiles, and a ratiometric pH-responsive method has been set up by comparing the relaxation enhancement at different magnetic field strengths.

Modulation of the platelet serotonin transporter by thermal balneotherapy: a study in healthy subjects

BACKGROUND

Although the beneficial effects of balneotherapy have been recognized since a long time, a few information is available on the biological mechanisms underlying them and the subjective feelings of increased well-being and mood.

AIM

The links between the serotonin (5-HT) system and mood prompted us to investigate the 5-HT platelet transporter (SERT), which is considered a reliable, peripheral marker of the same structure present in presynaptic neurons, in 30 healthy volunteers before (t0) and 30 minutes after (t1) thermal balneotherapy with ozonized water, as compared with a similar group who underwent a bath in non-mineral water. MATERIALS AN METHODS: The SERT was evaluated by means of the specific binding of 3H-paroxetine (3H-Par) to platelet membranes. Equilibrium-saturation binding data, the maximal binding capacity (Bmax) and the dissociation constant (Kd), were obtained by means of the Scatchard analysis.

RESULTS

The results showed that, while Bmax values did not change in both groups, the Kd values decreased significantly at t1 only in those subjects who bathed in ozonized water.

CONCLUSIONS

The results of this study, while showing a decrease of the dissociation constant (Kd) which is the inverse of affinity constant, of 3H-Par binding to SERT in all subjects after balneotherapy and not in those bathing in normal water, suggest that SERT modifications may be related to a specific effect of ozonized water and, perhaps, also to the increased sense of well-being.

Novel treatment options of binge eating disorder

Obesity is a major problem of modern societies that sometimes, but not necessarily, is associated with binge-eating disorder (BED), a relatively new disorder characterized by binge eating without purging. The purpose of this article is to review the rationale for the potential use of pharmacological treatments in BED, and the potential use of the recently proposed compounds. Therefore, a careful medline of published articles from 1980 to December 2010 was carried out using the following keywords: BED and treatment, topiramate, zonisamide, sibutramine, venlafaxine, duloxetine, ghrelin, opiate blockers. Single case reports, observational studies, opinion articles, and studies concerning adults with syndromes resulting in BED (i.e., night eating syndrome) were also reviewed. All examined papers would indicate that the pharmacological treatment of BED is still heterogenous and poorly established, mainly for the lack of controlled studies in large samples of patients. In any case, the data on serotonin and norepinephrine reuptake inhibitors and on novel anticonvulsants seem quite promising in terms of efficacy and tolerability. In addition, the preliminary findings on the possibility of modulating appetite through the interference with the ghrelin system suggest new and intriguing ways of intervention in BED.

Psychiatric disorders and mitochondrial dysfunctions

BACKGROUND

Mitochondria play a key role in the production of the cell energy. The final product of this process is adenosine triphosphate (ATP), used as a source of chemical energy. Besides this major role, mithocondria have been shown to be involved in other functions, such as signaling, cellular differentiation, cell death, as well as the control of the cell cycle and cell growth. The aim of this paper is to highlight the relationships between psychiatric disorders, especially schizophrenia, bipolar disorder (BD), autism, attention deficit-hyperactivity disorder (ADHD) and Alzheimer's dementia.

RESULTS

The review of the available literature indicate that different mitochondrial dysfunctions may accompany and/or be part of the clinical picture of some neuropsychiatric disorders.

CONCLUSIONS

Different data would indicate that mitochondrial dysfunctions may be involved in the pathophysiology of different neuropsychiatric disorders, given their key role in the cell energy metabolism. Moreover, they would greatly contribute to the process of neural apoptosis that should be at the basis of neurodegenerative disorders, such as schizophrenia, Alzheimer's dementia and the most severe forms of BD. In addition, data are available that mithocondrial abnormalities are present also in developmental disorders, such as autism and ADHD, although the studies aiming at elucidating the role of mithocondria in the onset and pathophysiology of all these conditions should be considered preliminary. In any case, taken together, these scattered findings would suggest novel drugs targeting protecting mitochondria from oxidative stress.
