Marked efficacy of Rituximab in multifocal motor neuropathy associated with chronic lymphocytic leukemia

The authors describe a patient who presented a multifocal motor neuropathy (MMN) associated with a high anti-ganglioside antibody (anti-GM1 and anti-GD1) titer at the clinical onset of a B-cell chronic lymphocytic leukemia (B-CLL). Immunomodulation (IVIg plus cyclosporine) resulted in a neurological improvement and reduced anti-ganglioside antibody titers, both of which remained stable for at least six years. After this period, the patient had a severe relapse of the neuropathy, which was independent of the clinical course of the B-CLL. Both IVIg and cyclophosphamide were ineffective, and the patient became tetraplegic within six months; in the meantime, the patient displayed an increased antiganglioside antibody titer. Treatment with rituximab (RTX), which is designed to selectively inhibit B cell function, resulted in a dramatic, prompt and long-lasting neurological improvement as well as a reduced anti-ganglioside antibody titer. Although there are no previous reports of MMN in patients with B-CLL, the efficacy of RTX in the treatment of MMN in this patient may be considered remarkable. The expansion of B-cell clones may be a prerequisite for RTX effectiveness in MMN, and in dysimmune neuropathies in general

Il contributo allo sviluppo della professione infermieristica delle congregazioni religiose del XIX secolo

RIASSUNTO Lo scopo del presente lavoro di ricerca storica è di esaminare il contributo allo sviluppo della professione infermieristica delle congregazioni religiose del XIX secolo prendendo come esempio le Suore di Maria Bambina conosciute anche come Suore della Carití  delle Sante Bartolomea Capitanio e Vincenza Gerosa. Sono state analizzate 63 fonti bibliografiche reperite nell'archivio storico Casa Madre delle Suore di Maria Bambina a Milano in via S. Sofia n.13, ad esclusione di una fonte reperita presso la Biblioteca Nazionale Braidense di Milano. Il lavoro di ricerca ha posto una lente d'ingrandimento sul contributo che le Suore di Maria Bambina hanno fornito, rispetto alle aree professionali e allo sviluppo degli attributi distintivi della professione infermieristica nell'ottica sociologica (Greenwood, 1980). Per l'analisi delle fonti documentarie è stato applicato il metodo di ricerca storica secondo Chabod (2006). Per l'esegesi delle fonti si è creata una griglia di analisi della fonte documentaria. Dall'aggregazione dei dati sono emersi due filoni d'indagine: il primo riguarda il ruolo di Suor Emilia Vinante come esperta per la professione infermieristica e il secondo per quanto attiene alla politica professionale promossa dalla Federazione Italiana Religiose Ospedaliere ( FIRO). Alla luce dei risultati della ricerca si può affermare che le congregazioni religiose hanno operato nell'ambito della professione infermieristica diventando una forza sociale in grado di incidere in modo determinante sullo sviluppo culturale e professionale degli infermieri. Parole Chiave: formazione, storia dell'assistenza infermieristica, infermiere religioseContribution of 19th-century religious congregations in the development of the nursing professionABSTRACT The purpose of this historical research project is to examine the contribution of 19th-century religious congregations in the development of the nursing profession, based on the historical example of the Sisters of Charity of Sts. Bartolomea Capitanio and Vincenza Gerosa (or the Sisters of the Holy Child Mary). To this end, sixty three volumes were analysed, all taken from the historical archive of the Generalate of the Sisters of the Holy Child Mary in Milan, in via S. Sofia n.13, with the exception of just one, taken from the Braidense National Library, also in Milan. This research project has highlighted the sociological contribution provided by the Sisters of the Holy Child Mary to the professional nature of nursing, and to the development of the distinctive features of the nursing profession (Greenwood, 1980). All documentary sources were analysed in line with the Chabod historical research method (2006), and for their critical interpretation, a scheme of analysis was created. Two lines of investigation emerged from the data collected: the role of Sister Emilia Vinante as an expert with regard to the nursing profession, and the professional strategies promoted by FIRO (Federation of Italian Religious Nurses). Based on the conclusions of the research project, it may be stated that religious congregations contributed greatly to the nursing profession, leaving a decisive mark on the cultural and professional development of nurses. Key words: nursing education, historical research, religiuos nurs

Optical behaviors, surface treatment, adhesion, and clinical indications of zirconia-reinforced lithium silicate (ZLS): A narrative review

Objectives: The present narrative review was focused on the optical properties, surface treatment, adhesion, and clinical indications of zirconia-reinforced lithium silicate ceramics (ZLS) for Computer-aided design / Computer-aided manufacturing (CAD/CAM) technologies. Data/sources: A literature search was performed by 3 calibrated independent researchers on PubMed, Scopus, Embase, Google Scholar, Dynamed, and Open Grey. The criteria for inclusion were: 1) papers addressing at least one of the following variables about ZLS: optical properties, surface treatment, adhesion, and clinical indications; 2) in vitro, in silico, or in vivo studies; 3) case reports; 4) systematic reviews. The exclusion criteria were: 1) animal studies; 2) non-dental studies; 3) studies only focusing on ZLS used in the heat-pressed process. Study selection: 98 records among in vitro studies and case reports were included. Conclusions: Despite the promising microstructure characteristics of ZLS, increased translucency compared to lithium disilicate ceramics (LS2) was not proven, but acceptable color changes and stability were reported. Mechanical polishing was the most effective method to reduce surface roughness. Moreover, machinability and handling of ZLS resulted harder than LS2. Conventional acid etching procedures seemed effective in conditioning ZLS surface, but no protocol has been established yet. Besides, silane-coupling and dual-curing resin cements were recommended. Clinical significance: ZLSs can be used for anterior and posterior fixed single-unit CAD/CAM restorations onto both natural teeth and implants, but do not seem to represent a viable treatment option for endocrowns onto posterior teeth or fixed dental prostheses

Brexpiprazole as a new approach of treatment in somatization disorder

© 2022 Published by Elsevier Ltd on behalf of International Society for the Study of Emerging Drugs. This is an open access article under the CC-BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4.0/)Introduction: Somatic symptom disorder (SSD) is a mental disorder that involves one or more physical symptoms (e.g. palpitations, dizziness, diarrhoea, limb weakness, pain, and pseudo neurological symptoms) accompanied by one or more thoughts, feelings, and/or behaviours related to the somatic symptom(s) resulting in significant distress and/or dysfunction lasting for more than 6 months. At now the SSD can be refractory to psychiatric intervention including antidepressants, antiepileptics, and antipsychotics as well as the effectiveness of many of these treatments is limited. The objective of this study was to report the effectiveness of a third-generation antipsychotic drug brexpiprazole for treatment of a case of SSD together with the serotonin selective reuptake inhibitor (SSRI) fluvoxamine. Methods: A single case study of a 59-year-old female with SSD was here performed. Findings: After 4 weeks of treatment brexpiprazole, together with lamotrigine and fluvoxamine, was here effective in decreasing both depressive and anxiety symptoms, normalising previous unusual thought contents and of related behaviours. The patient reported an overall good response and started to function again in important domains of life. No adverse events occurred. Conclusion: To our knowledge, this is the first case showing Brexpiprazole effective for the treatment of a case of SSD as add-on to other drugs.Peer reviewedFinal Published versio

Update on monitoring of magnetic and electromagnetic tectonic signals in Central Italy

A network of three absolute magnetometer stations and the geomagnetic observatory of LAquila (42°23N, 13°19E) monitors possible seismo- or tectonomagnetic effects in Central Italy, using LAquila Observatory as a reference for differentiation. A system of two VLF search coil wide-band antennas, working in two different frequency bands, at the LAquila Observatory, monitors possible electromagnetic effects related to seismic events occurring in Central Italy. Absolute magnetic field observations and VLF signals have been collected for several years. In particular the tectono-magnetic network started its operations in 1989. In this paper we report on the time variation of above mentioned data for the most recent years 2002 and 2003, also in connection with older measurements time series; we also report on seismic activity recorded in this area by the national seismic network. In the above mentioned time interval, no strong earthquake activity was recorded, and at the same time no clear evidence for magnetic or electromagnetic signals related to seismic events was found

Clinical and Socio-Demographic Determinants of Self-Care Behaviours in Patients with Heart Failure and Diabetes Mellitus: A Multicentre Cross-Sectional Study

Background Self-care is vital for patients with heart failure to maintain health and quality of life, and it is even more vital for those who are also affected by diabetes mellitus, since they are at higher risk of worse outcomes. The literature is unclear on the influence of diabetes on heart failure self-care as well as on the influence of socio-demographic and clinical factors on self-care. Objectives (1) To compare self-care maintenance, self-care management and self-care confidence of patients with heart failure and diabetes versus those heart failure patients without diabetes; (2) to estimate if the presence of diabetes influences self-care maintenance, self-care management and self-care confidence of heart failure patients; (3) to identify socio-demographic and clinical determinants of self-care maintenance, self-care management and self-care confidence in patients with heart failure and diabetes. Design Secondary analysis of data from a multicentre cross-sectional study. Setting Outpatient clinics from 29 Italian provinces. Participants 1192 adults with confirmed diagnosis of heart failure. Methods Socio-demographic and clinical data were abstracted from patients’ medical records. Self-care maintenance, self-care management and self-care confidence were measured with the Self-Care of Heart Failure Index Version 6.2; each scale has a standardized score from 0 to 100, where a score \u3c70 indicates inadequate self-care. Multiple linear regression analyses were performed. Results Of 1192 heart failure patients, 379 (31.8%) had diabetes. In these 379, heart failure self-care behaviours were suboptimal (means range from 53.2 to 55.6). No statistically significant differences were found in any of the three self-care measures in heart failure patients with and without diabetes. The presence of diabetes did not influence self-care maintenance (p = 0.12), self-care management (p = 0.21) or self-care confidence (p = 0.51). Age (p = 0.04), number of medications (p = 0.01), presence of a caregiver (p = 0.04), family income (p = 0.009) and self-care confidence (p \u3c 0.001) were determinants of self-care maintenance. Gender (p = 0.01), number of medications (p = 0.004) and self-care confidence (p \u3c 0.001) were significant determinants of self-care management. Number of medications (p = 0.002) and cognitive function (p \u3c 0.001) were determinants of self-care confidence. Conclusions Self-care was poor in heart failure patients with diabetes mellitus. This population needs more intensive interventions to improve self-care. Determinants of self-care in heart failure patients with diabetes mellitus should be systematically assessed by clinicians to identify patients at risk of inadequate self-care

Therapeutic Potentials of Ketamine and Esketamine in Obsessive–Compulsive Disorder (OCD), Substance Use Disorders (SUD) and Eating Disorders (ED): A Review of the Current Literature

The obsessive–compulsive spectrum refers to disorders drawn from several diagnostic categories that share core features related to obsessive–compulsive disorder (OCD), such as obsessive thoughts, compulsive behaviors and anxiety. Disorders that include these features can be grouped according to the focus of the symptoms, e.g., bodily preoccupation (i.e., eating disorders, ED) or impulse control (i.e., substance use disorders, SUD), and they exhibit intriguing similarities in phenomenology, etiology, pathophysiology, patient characteristics and clinical outcomes. The non-competitive N-methyl-D-aspartate receptor (NMDAr) antagonist ketamine has been indicated to produce remarkable results in patients with treatment-resistant depression, post-traumatic stress disorder and OCD in dozens of small studies accrued over the past decade, and it appears to be promising in the treatment of SUD and ED. However, despite many small studies, solid evidence for the benefits of its use in the treatment of OCD spectrum and addiction is still lacking. Thus, the aim of this perspective article is to examine the potential for ketamine and esketamine in treating OCD, ED and SUD, which all involve recurring and intrusive thoughts and generate associated compulsive behavior. A comprehensive and updated overview of the literature regarding the pharmacological mechanisms of action of both ketamine and esketamine, as well as their therapeutic advantages over current treatments, are provided in this paper. An electronic search was performed, including all papers published up to April 2021, using the following keywords (“ketamine” or “esketamine”) AND (“obsessive” OR “compulsive” OR “OCD” OR “SUD” OR “substance use disorder” OR “addiction” OR “craving” OR “eating” OR “anorexia”) NOT review NOT animal NOT “in vitro”, on the PubMed, Cochrane Library and Web of Science online databases. The review was conducted in accordance with preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. The use and efficacy of ketamine in SUD, ED and OCD is supported by glutamatergic neurotransmission dysregulation, which plays an important role in these conditions. Ketamine’s use is increasing, and preliminary data are optimistic. Further studies are needed in order to better clarify the many unknowns related to the use of both ketamine and esketamine in SUD, ED and OCD, and to understand their long-term effectiveness.Peer reviewedFinal Published versio

Tectonomagnetic and VLF electromagnetic signals in Central Italy

Tectonomagnetic field observations from absolute magnetic field level measurements were undertaken in Central Italy in an area extending between latitude 41°N and 43°N and between longitude 13°E and 15°E. Moreover,natural electromagnetic signals from a system of two VLF search coil wide-band antennas were collected at the geomagnetic observatory of L Aquila (42º23'N, 13º19'E). The analysis of these data allowed the investigation of the electromagnetic properties of the study area at different time and spatial lengthscales. Tectonomagnetic field observations were obtained comparing data simultaneously recorded at three magnetometer stations using L'Aquila Observatory as a reference for differentiation. We report on the time evolution of magnetic and electromagnetic indicators related to local and regional seismic activity

Coffee Restores Expression of lncRNAs Involved in Steatosis and Fibrosis in a Mouse Model of NAFLD

Background and aim: Coffee intake exerts protective effects against non-alcoholic fatty liver disease (NAFLD), although without fully cleared mechanisms. In this study we aimed to assess whether coffee consumption may influence the expression of long non-coding RNAs (lncRNAs) in the liver. Methods: C57BL/6J mice were fed a 12-week standard diet (SD), high-fat diet (HFD) or HFD plus decaffeinated coffee solution (HFD + coffee). Expression of specific lncRNAs involved in NAFLD was analyzed by real-time PCR. For the most differentially expressed lncRNAs, the analysis was also extended to their mRNA targets. Results: Decaffeinated coffee intake reduced body weight gain, prevented NAFLD, lowered hyperglycemia and hypercholesterolemia. NAFLD was associated with lower hepatic expression of Gm16551, a lncRNA inhibiting de novo lipogenesis, and higher expression of H19, a lncRNA promoting fibrogenesis. Coffee intake restored Gm16551 to levels observed in lean mice and downregulated gene expression of its targets acetyl coenzyme A carboxylase 1 and stearoyl coenzyme A desaturase 1. Furthermore, coffee consumption markedly decreased hepatic expression of H19 and of its target gene collagen alpha-1(I) chain; consistently, in mice fed HFD + coffee liver expression of αSMA protein returned to levels of mice fed SD. Expression of lncRNA involved in circadian clock such as fatty liver-related lncRNA 1 (FLRL1) and fatty liver-related lncRNA 2 (FLRL2) were upregulated by HFD and were also modulated by coffee intake. Conclusion: Hepatoprotective effects of coffee may be depending on the modulation of lncRNAs involved in key pathways of NAFLD onset and progression
