A Literature Systematic Review with Meta-Analysis of Symptoms Prevalence in Covid-19: the Relevance of Olfactory Symptoms in Infection Not Requiring Hospitalization.

PURPOSE OF REVIEW: To investigate the association between the olfactory dysfunction and the more typical symptoms (fever, cough, dyspnoea) within the Sars-CoV-2 infection (COVID-19) in hospitalized and non-hospitalized patients. RECENT FINDINGS: PubMed, Scopus and Web of Science databases were reviewed from May 5, 2020, to June 1, 2020. Inclusion criteria included English, French, German, Spanish or Italian language studies containing original data related to COVID19, anosmia, fever, cough, and dyspnoea, in both hospital and non-hospital settings. Two investigators independently reviewed all manuscripts and performed quality assessment and quantitative meta-analysis using validated tools. A third author arbitrated full-text disagreements. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), 11 of 135 studies fulfilled eligibility. Anosmia was estimated less prevalent than fever and cough (respectively rate difference = - 0.316, 95% CI: - 0.574 to - 0.058, Z = - 2.404, p < 0.016, k = 11 and rate difference = - 0.249, 95% CI: - 0.402 to - 0.096, Z = - 3.185, p < 0.001, k = 11); the analysis between anosmia and dyspnoea was not significant (rate difference = - 0.008, 95% CI: - 0.166 to 0.150, Z = - 0.099, p < 0.921, k = 8). The typical symptoms were significantly more frequent than anosmia in hospitalized more critical patients than in non-hospitalized ones (respectively [Q(1) = 50.638 p < 0.000, Q(1) = 52.520 p < 0.000, Q(1) = 100.734 p < 0.000). SUMMARY: Patient with new onset olfactory dysfunction should be investigated for COVID-19. Anosmia is more frequent in non-hospitalized COVID-19 patients than in hospitalized ones.

Enhancing adherence to antipsychotic treatment for bipolar disorders. Comparison of mobile app-based psychoeducation, group psychoeducation, and the combination of both: protocol of a three-arm single-blinded parallel-group multi-centre randomised trial.

Group Psychoeducation (PE) is an effective strategy to enhance adherence to antipsychotic treatment in Bipolar Disorders (BD). However, it requires attendance to weekly sessions during a period of about 6 months. This may impede its application for those patients living far from mental health centres, resulting inequality in access to evidence-based care. Therefore, there is an increasing need to find new efficient strategies to deliver and extend PE programs to a wider population of BD patients. Mobile apps are a cost-effective way to deliver PE. In the Italian healthcare context, no evidence about the use of apps is available. The current paper presents the protocol about the development of a smartphone app to deliver PE for BD and the protocol for a trial assessing its effectiveness. In euthymic BD patients, the study will compare the adherence rates to antipsychotics between PE delivered through Bipolar mobile Application (Bip.App), group PE and a combination of both, will investigate demographic, socio-cultural and clinical predictors of lower adherence in the arms, and will investigate whether PE combined with Bip.App is associated with lower risk of recurrence of (hypo)manic and depressive episodes than group PE alone, and assess the feasibility and satisfaction for Bip.App. Participants will be recruited from mental health centres and included if they are 18-65 year-old, have primary BD in the euthymic phase, they have been prescribed a second-generation oral antipsychotic as a maintenance/prophylactic therapy for at least 1 year, they have not undergone a structured protocol of PE for BD, they have access to a smartphone and sufficient competence in using it. Participants will be excluded if they have neurological disease, mental retardation or learning disability, psychosis, limited fluency in Italian. Adherence will be assessed through count pills, blood levels, and self-reported adherence. A single-blinded parallel-group superiority multi-centre randomised controlled trial design will be used.

Clinical risk management in High-Security Forensic Psychiatry Residences. Protecting patients and health professionals: perspectives and critical issues of the Law 81/2014.

The Italian Law n. 9/2012 provided the Italian Regions with a new decisional role by demanding the management/rehabilitation of prisoners judged as partially/fully mentally ill to care and protection delivered by the psychiatric services of the Regional Health Service. Healthcare has to be guaranteed by the so-called High-Security Forensic Psychiatry Residences (Italian: Residenze per l'Esecuzione delle Misure di Sicurezza: REMS) and by community mental health centres. Ensuring patients' and professionals' health and safety is a complex issue which requires effective strategies to cope with several structural, technological, and organisational problems. The present paper summarises the historical evolution of the Italian laws towards the development of the High-Security Forensic Psychiatry Residences in Italy, focusing specifically on the Tuscany Region situation. The paper also presents the key issues emerging after the implementation of the Law 81/2014 which complemented the Law 9/2012. Since these reforms included the need for assessing to what extent the patient may be considered as a danger to society and for ensuring the safety of National Health Service (NHS) professionals, they underscored the importance of a preventive use of specific clinical governance tools aimed to reduce risk of adverse events. The present work has the strength of proposing a new, evidence-based scientific approach to the implementation of assessment and care pathways in High-Security Forensic Psychiatry Residences.

Acquired haemophilia A as a secondary autoimmune disease after alemtuzumab treatment in multiple sclerosis: A case report.

Alemtuzumab is a highly effective monoclonal antibody for the treatment of multiple sclerosis (MS). During the immune reconstitution following the use of this treatment severe secondary autoimmune diseases (SADs) can develop. We present the case of a patient affected by active MS who failed to achieve disease control with several disease-modifying drugs and was thereafter successfully treated with alemtuzumab, obtaining no evidence of disease activity and a high quality of life. Twenty months after the first infusion of alemtuzumab the patient developed acquired haemophilia A (AHA), a treatable but potentially lifethreatening condition that should be considered a possible SADs associated to this drug. In order to allow an early diagnosis and to prevent possible complications of AHA, routine coagulation tests (prothrombin time and activated partial thromboplastin time) should be included in the laboratory serological monitoring of patients treated with alemtuzumab.

Workers safety in public psychiatric services: problems, laws and protections.

The dramatic case of murder of a psychiatrist during her service in her public office (Centro di Salute Mentale of Bari-Libertà) has led the authors to reflect on the safety of workplaces, in detail of public psychiatric services. It is in the light of current legislation, represented by the Legislative Decree of April 9th, 2008 no. 81, which states the implementing rules of Law 123/2007. In particular, the Authors analyzed the criticalities of the application of this Law, with the aim of safeguarding the health and safety of the workers in all psychiatric services (nursing departments, outpatient clinics, community centers, day care centers, etc.). The Authors suggest the need to set up an articulated specific organizational system of risk assessment of psychiatric services, that can prevent and protect the workers from identified risks, and finally to ensure their active participation in prevention and protection activities, in absence of which specific profiles of responsibility would be opened up to the employers.

Borderline ovarian tumors, fertility-sparing surgery and pregnancy outcome.

BACKGROUND: Borderline ovarian tumors (BOTs) represent a type of epithelial tumors having a biologic intermediate behavior between clearly malignant and straight benign tumors. Most of BOTs interest women during fertile age, for which it is necessary to consider a fertility sparing surgery. AIM: To evaluate the clinical aspects and pregnancy rate of women affected by borderline ovarian tumors who have undergone fertility sparing surgery. PATIENTS AND METHODS: A study of 22 patients affected by BOTs who have been treated with a fertility sparing surgery was conducted between January 2005 and October 2011 at Sant'Andrea Hospital, "Sapienza" University of Rome. The patients' characteristics analyzed were: age, histological type, tumor size, adnexal surgery, pre-operative serum CA-125, diagnostic circumstances, number of patients who became pregnant and number of overall pregnancies. RESULTS: Among the 22 patients treated with a fertility sparing surgery, only sixteen wanted to get pregnant. Eleven patents out of 16 accomplished it. The pregnancy rate was 68.7%. CONCLUSIONS: Fertility sparing surgery can be considered a safe procedure for young women affected by borderline ovarian tumors.

[Theoric hints on the quality perception in health care services concept]. / Cenni teorici sul concetto di qualità percepita in sanità.

topic in healthcare services management. In this article we try to summarize the most relevant theoretical approaches, providing a general definition of "quality" and trying a possible generic relationship between the concepts of "perceived quality" and "client satisfaction". Finally, we examine some methodological problems, concerning surveys on quality perception in healthcare services. Through the analysis of some examples, we will compare two methodologies, coming from the University of Siena (Italy) and from the Picker Institute Europe in Oxford (United Kingdom).

Perinatal risk factors and mode of delivery correlated to survival and psychomotor disability in extremely low birth weight infants.

BACKGROUND/AIMS: Extreme preterm birth, <28 weeks of gestation, represents a public health concern with major economic implications, being the leading cause of neonatal mortality and morbidity. METHODS: A single-centre retrospective cohort study was carried out to assess the role of caesarean section and to identify perinatal factors affecting neonatal survival and psychomotor development in these infants. 57 cases with complete maternal, obstetrical and neonatological information were selected for this study and neurological development was assessed for at least 18 months of life. RESULTS: Infant survival and neurological morbidity rates were directly and inversely correlated to birth weights and gestational age at birth, respectively. In multivariate analysis only extreme prematurity (

Smoking during pregnancy: a risk factor for peripheral neuropathy?

Studies dealing with the outcomes of developmental carbon monoxide (CO) exposure on myelination in rat offspring are reviewed. Prenatal CO exposure from gestational day 0 to gestational day 20 impairs myelin deposition around peripheral axons resulting in a significant hypomyelination in juvenile and adult rats. Myelin protein patterns analyzed by SDS-polyacrylamide gel electrophoresis and lipid patterns analyzed by the HPTLC method are not altered in both peripheral and central nervous systems of CO-exposed offspring. Interestingly, when sphingomyelin is extracted and purified, the derivatization by OPA reagent and analysis by reversed-phase HPLC reveal a significant increase in sphingosine levels in peripheral nervous system but not in central nervous system of CO-exposed rats. The above morphological and biochemical alterations are not accompanied by motor disabilities.

Vasculogenic mimicry by bone marrow macrophages in patients with multiple myeloma.

Bone marrow macrophages of patients with active and nonactive multiple myeloma (MM), monoclonal gammopathies of undetermined significance (MGUS) and benign anemia (controls) were stimulated for 7 days with vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF), and analysed for the expression of endothelial cell (EC) markers by reverse transcription (RT)-PCR, real-time RT-PCR, western blot and immunofluorescence. Their vasculogenic ability was investigated in vitro in a Matrigel assay and in vivo on bone marrow biopsies through dual immunofluorescence and confocal laser microscopy. Active MM macrophages exposed to VEGF and bFGF acquired EC markers and formed capillary-like structures mimicking paired bone marrow ECs (multiple myeloma patient-derived endothelial cells, MMECs), with major responsiveness compared to macrophages from nonactive MM, MGUS or controls. Bone marrow biopsies of active MM harbored 'mosaic' vessels, being formed by MMECs, EC-like macrophages and macrophages themselves. These figures were rare in nonactive MM and absent in MGUS or controls. Our data indicate that macrophages contribute to build neovessels in active MM through vasculogenic mimicry, and this ability proceeds parallel to progression of the plasma cell tumors. Macrophages may be a target for the MM antivascular treatment.

Neurofunctional effects of developmental sodium fluoride exposure in rats.

Contrasting studies on the toxic effects of sodium fluoride (NaF) during developmental stages of Wistar rats, lead us to investigate the neurofunctional effects caused by its perinatal exposure, devoid of any overt sign of toxicity and/or gross malformation. NaF solution was administered to pregnant rats by intragastric gavage at a daily dose of 2.5 and 5.0 mg/kg from gestational day 0 to day 9 after parturition. Developmental NaF exposure caused sex and dose specific behavioural deficits which affected males more than females in the majority of the evaluated end-points. In particular, the perinatal exposure to NaF 5.0 mg/kg, significantly affected learning, memory, motor coordination and blood pressure only in male rats. Conversely, a lack of habituation upon the second presentation of the objects and failure in the ability to discriminate between the novel and the familiar object were observed only in NaF 5.0 mg/kg female rats. Finally, a significant impairment of sexual behaviour was observed in male rats at both NaF dose levels. The present data indicate that perinatal rat exposure to NaF results in long lasting functional sex-specific alterations which occur at fluoride levels approaching those experienced by offspring of mothers.

Acute exposure to methylmercury at two developmental windows: focus on neurobehavioral and neurochemical effects in rat offspring.

The neurobehavioral and neurochemical effects produced by prenatal methylmercury exposure (8 mg/kg, gestational-days 8 or 15), were investigated in rats. On postnatal day 40, animals exposed to methylmercury and tested in the open field arena, showed a reduction in the number of rearings, whereas the number of crossings and resting time was not altered with respect to the age-matched control rats. The methylmercury-exposed groups showed a lower level of exploratory behavior as well as an impairment in habituation and working memory when subjected to the novel object exploration task. The neophobia displayed by methylmercury-exposed rats is unlikely to be attributed to a higher degree of anxiety. Prenatal methylmercury exposure did not affect motor coordination or motor learning in 40-day-old rats subjected to the balance task on a rotating rod, and it did not impair the onset of reflexive behavior in pups screened for righting reflex, cliff aversion and negative geotaxis. In cortical cell cultures from pups exposed to methylmercury during gestation, basal extracellular glutamate levels were higher, whereas the KCl-evoked extracellular glutamate levels were lower than that measured in cultures from rats born to control mothers. In addition, a higher responsiveness of glutamate release to N-methyl-D-aspartic acid receptor activation was evident in cortical cell cultures from pups born from methylmercury-treated dams than in cultures obtained from control rats. The present results suggest that acute maternal methylmercury exposure induces, in rat offspring, subtle changes in short-term memory as well as in exploratory behavior. These impairments seem to be associated to alterations of cortical glutamatergic signaling.

[Questionnaire of perceived quality (QQP): a study on the differences of gender]. / Questionario di qualità percepita (QQP): uno studio sulle differenze di genere.

In the present paper we analyze the psychometric properties of an Italian questionnaire measuring the perceived quality of health services (Questionnaire of Perceived Quality; Coluccia, Ferretti, Lorini, Calamai, 2002). Subjects answered 14 questions subdivided into four factors (i.e. Satisfaction regarding Medical Doctors, Nurses, Auxiliary Staff, and Hospital Structure). We administered the questionnaire to 1,600 patients in the "Le Scotte" Hospital of Siena. According to structural equation modeling, we studied the dimensionality of the questionnaire using confirmatory factor analysis and, successively, we studied differences in gender using Multi-sample analysis. Results show significant gender differences for two dimensions (i.e. Satisfaction regarding Nurses and Satisfaction regarding Hospital Structures). Females, compared to males, express more negative evaluations in these two factors.

Glutamic acid decarboxylase and GABA immunoreactivities in the cerebellar cortex of adult rat after prenatal exposure to a low concentration of carbon monoxide.

Glutamic acid decarboxylase and GABA immunoreactivities were qualitatively and quantitatively evaluated in the cerebellar cortex of adult rats prenatally exposed to a low concentration of carbon monoxide (75 parts per million). Carbon monoxide-exposed and control rats were perfused with modified Bouin's fluid and their cerebella were embedded in paraffin. Sections from the vermis of each cerebellum were stained with Toluidine Blue or assayed with anti-glutamic acid decarboxylase 65/67 or with anti-GABA antisera. In the Toluidine Blue-stained sections, no differences were observed in the microscopic structure of the cerebellar cortex between carbon monoxide-exposed rats and controls. The distribution patterns of glutamic acid decarboxylase and GABA immunoreactivities in the cerebellar cortex of the treated animals were qualitatively comparable to those of the controls, and in accordance with previous descriptions of glutamic acid decarboxylase and GABA immunoreactivities in the rat cerebellar cortex. However, quantitative analyses demonstrated a significant reduction of immunoreactivities to both substances in the exposed rats in comparison with the controls. The reduction regarded: in the molecular layer, the number of glutamic acid decarboxylase/GABA-immunoreactive neuronal bodies and of axon terminals and the area they covered; in the Purkinje neuron layer, the number and the area covered by glutamic acid decarboxylase/GABA immunoreactive axon terminals. The differences detected in the prenatally exposed adult rats could be due to carbon monoxide-induced impairment of the differentiation of cerebellar GABA synthesizing neurons. A consequently diminished synthesis of GABA might account for some behavioral disorders detected in adult rats submitted to the same experimental procedure.

Anaplastic lymphoma kinase and its signalling molecules as novel targets in lymphoma therapy.

A crucial issue in the development of molecularly-targeted anticancer therapies is the identification of appropriate molecules whose targeting would result in tumour regression with a minimal level of systemic toxicity. Anaplastic lymphoma kinase (ALK) is a transmembrane receptor tyrosine kinase, normally expressed at low levels in the nervous system. As a consequence of chromosomal translocations involving the alk gene (2p23), ALK is also aberrantly expressed and constitutively activated in approximately 60% of CD30+ anaplastic large cell lymphomas (ALCLs). Due to the selective overexpression of ALK in tumour cells, its direct involvement in the process of malignant transformation and its frequent expression in ALCL patients, the authors recognise ALK as a suitable candidate for the development of molecularly targeted strategies for the therapeutic treatment of ALK-positive lymphomas. Strategies targeting ALK directly or indirectly via the inhibition of the protein networks responsible for ALK oncogenic signalling are discussed.

Transgenic mice expressing F3/contactin from the transient axonal glycoprotein promoter undergo developmentally regulated deficits of the cerebellar function.

We have shown that transgenic transient axonal glycoprotein (TAG)/F3 mice, in which the mouse axonal glycoprotein F3/contactin was misexpressed from a regulatory region of the gene encoding the transient axonal glycoprotein TAG-1, exhibit a transient disruption of cerebellar granule and Purkinje cell development [Development 130 (2003) 29]. In the present study we explore the neurobehavioural consequences of this mutation. We report on assays of reproductive parameters (gestation length, litter size and offspring viability) and on somatic and neurobehavioural end-points (sensorimotor development, homing performance, motor activity, motor coordination and motor learning). Compared with wild-type littermates, TAG/F3 mice display delayed sensorimotor development, reduced exploratory activity and impaired motor activity, motor coordination and motor learning. The latter parameters, in particular, were affected also in adult mice, despite the apparent recovery of cerebellar morphology, suggesting that subtle changes of neuronal circuitry persist in these animals after development is complete. These behavioural deficits indicate that the finely coordinated expression of immunoglobulin-like cell adhesion molecules such as TAG-1 and F3/contactin is of key relevance to the functional, as well as morphological maturation of the cerebellum.

Antinutritional effects of fumonisin B1 and pathophysiological consequences.

Due to its structural similarity with sphingosine, fumonisin B(1) (FB(1)) inhibits ceramide synthase (a key enzyme of sphingolipid biosynthesis) leading to an intracellular accumulation of sphingoid bases with a consequent increase of sphinganine/sphingosine (SA/SO) ratio. In adult male rats, dietary exposure to fumonisin induces a significant increase in both SA concentrations and SA/SO ratio in kidney, but not in liver and brain, as well as a significant reduction of body weight gain. Regarding the brain, the developing rat is more sensitive to FB(1) than the adult rat. FB(1) treatment produces in the forebrain and brainstem: (i) an increase in SA levels and SA/SO ratio, (ii) a reduction in myelin deposition, and (iii) an impairment of 2',3'-cyclic nucleotide 3'-phosphohydrolase (CNP) activity. FB(1) effects on myelin are similar to those produced by starvation (temporary removal of pups from dam during postnatal period), thus suggesting that hypomyelination could be due, at least partly, to a nutritional deficiency. Finally, FB(1) reduces the uptake of folate in different cell lines. The resulting folate deficiency could explain the association of FB(1) exposure with neural tube defects.

Prenatal low-level exposure to CO alters postnatal development of hippocampal nitric oxide synthase and haem-oxygenase activities in rats.

The effects of prenatal CO exposure (150 ppm from days 0 to 20 of pregnancy) on the postnatal development of hippocampal neuronal NO synthase (nNOS) and haem-oxygenase (HO-2) isoform activities in 15-, 30- and 90-d-old rats were investigated. Unlike HO-2, hippocampal nNOS activity increased from postnatal days 15-90 in controls. Prenatal CO produced a long-lasting decrease in either nNOS or HO-2. The results suggest that the altered developmental profile of hippocampal nNOS and HO-2 activities could be involved in cognitive deficits and long-term potentiation dysfunction exhibited by rats prenatally exposed to CO levels resulting in carboxyhaemoglobin (HbCO) levels equivalent to those observed in human cigarette smokers.

Translocation T(4;14)(p16.3;q32) is a recurrent genetic lesion in primary amyloidosis.

Primary amyloidosis is a fatal disorder characterized by low numbers of clonal plasma cells in the bone marrow and the systemic deposition of light chain fragments in the form of amyloid. The molecular pathobiology of amyloidosis is primarily unknown. Recently, a novel karyotypically undetectable t(4;14)(p16.3;q32) translocation has been identified in approximately 20% of multiple myeloma patients. The translocation leads to the apparent deregulation of two genes located on 4p16.3, the fibroblast growth-factor receptor 3 (FGFR3), and the putative transcription factor multiple myeloma SET domain (MMSET), and to the generation of IGH/MMSET hybrid transcripts. In this study, we investigated the presence of the t(4;14) translocation in 42 AL patients using a reverse transcriptase-polymerase chain reaction assay for the detection of IGH/MMSET transcripts. Chimeric transcripts were found in six patients (14%) and were consistent with a 4p16.3 breakpoint involving intron 3 and juxtaposing IGH regions to exon 4. In three of these cases, hybrid transcripts juxtaposing IGH regions to exon 5 were also observed and were probably the result of an alternative splicing skipping exon 4. Because all of the fusion transcripts (six of six) excluded exon 3, the first translated MMSET exon, only putative 5' truncated MMSET proteins could be generated. In conclusion, our results demonstrate that the t(4;14)(p16.3;q32) translocation is a recurrent genetic lesion in primary amyloidosis.

In vivo neurochemical effects of the acetylcholinesterase inhibitor ENA713 in rat hippocampus.

Oral ENA713 (0.5, 1.5 and 4.5 mg/kg), an acetylcholinesterase inhibitor (AChEI), dose-dependently enhanced extracellular acetylcholine concentrations in the hippocampus of freely moving rats. This effect was paralleled by changes in both noradrenergic and dopaminergic transmission. In particular, ENA713 significantly decreased noradrenaline concentrations, whereas it significantly increased homovanillic acid levels, without affecting dopamine concentrations. Neither serotonin nor gamma-aminobutyric acid levels were modified by ENA713. These findings extend the neurochemical profile of ENA713 and suggest that it could be useful for the treatment of Alzheimer-type dementia which is associated with multiple neurotransmitter abnormalities in the brain.
