RESUMO
The ongoing pandemic of COVID-19 has underlined the importance of adopting effective infection prevention and control (IPC) measures in hospital and community settings. Ultraviolet (UV)-based technologies represent promising IPC tools: their effective application for sanitation has been extensively evaluated in the past but scant, heterogeneous and inconclusive evidence is available on their effect on SARS-CoV-2 transmission. With the aim of pooling the available evidence on the efficacy of UV technologies against coronaviruses, we conducted a systematic review following PRISMA guidelines, searching Medline, Embase and the Cochrane Library, and the main clinical trials' registries (WHO ICTRP, ClinicalTrials.gov, Cochrane and EU Clinical Trial Register). Quantitative data on studies' interventions were summarized in tables, pooled by different coronavirus species and strain, UV source, characteristics of UV light exposure and outcomes. Eighteen papers met our inclusion criteria, published between 1972 and 2020. Six focused on SARS-CoV-2, four on SARS-CoV-1, one on MERS-CoV, three on seasonal coronaviruses, and four on animal coronaviruses. All were experimental studies. Overall, despite wide heterogenicity within included studies, complete inactivation of coronaviruses on surfaces or aerosolized, including SARS-CoV-2, was reported to take a maximum exposure time of 15 min and to need a maximum distance from the UV emitter of up to 1 m. Advances in UV-based technologies in the field of sanitation and their proved high virucidal potential against SARS-CoV-2 support their use for IPC in hospital and community settings and their contribution towards ending the COVID-19 pandemic. National and international guidelines are to be updated and parameters and conditions of use need to be identified to ensure both efficacy and safety of UV technology application for effective infection prevention and control in both healthcare and non-healthcare settings.

COVID-19 is a global health threat with a huge number of confirmed cases and deaths all over the world. Human-to-human transmission via respiratory droplets and contact with aerosol-infected surfaces are the major routes of virus spread. Because SARS-CoV-2 can remain in the air and on surfaces from several hours to several days, disinfection of frequently touched surfaces and critical rooms, in addition to observing individual hygiene tips, is required to reduce the virus spreading. Here we report on an investigation into the use of gaseous ozone as a potentially effective sanitizing method against the new coronavirus.

BACKGROUND AND AIMS: Golimumab has an established exposure-response relationship in patients with ulcerative colitis [UC]. However, the association of serum golimumab trough levels [TL] with objective markers of disease activity, such as endoscopic and histological activity scores and concentrations of biomarkers, remains less understood. This report describes the relationship of serum golimumab TL at the end of the induction period [Week 6] with clinical, endoscopic, histological, and biomarker parameters. METHODS: This was an open-label, uncontrolled, prospective and interventional study. Moderate to severely active UC patients naïve to biologic therapy were treated with golimumab. Serum golimumab TL and faecal calprotectin levels were measured at baseline [Week 0 of induction] and Week 6. RESULTS: A total of 34 patients completed the induction phase [Week 6] and were included in this analysis. Overall, 47.1% and 14.7% of patients achieved clinical response and remission with significantly higher serum golimumab TL in patients with early response or remission [3.7 µg/mL vs 1.3 µg/mL, p = 0.0013; and 3.1 µg/mL vs 1.7 µg/mL, p = 0.0164, respectively]. In addition, golimumab TL were significantly higher in patients achieving histological remission [4.2 µg/mL vs 1.7 µg/mL, p = 0.0049]. Week 6 golimumab TL were inversely correlated with the total Mayo score [rs = -0.546; p = 0.0008], the Mayo endoscopic subscore [rs = -0.381; p = 0.0262], the Geboes histological activity score [rs = -0.464; p = 0.0057], and faecal calprotectin levels [rs = -0.497; p = 0.0044]. CONCLUSIONS: A higher early exposure to golimumab is associated with a better objective response in active UC patients and appears to drive the outcome at Week 6.

The aim of this literature review was to develop clinical guidelines for the prevention and control of needlerelated pain in newborn infants. The guidelines were developed by the Italian Society of Neonatology, using the Grading of Recommendations, Assessment, Development and Evaluation approach, based on the assessment of 232 papers published between 1986 and 2015. The quality of the evidence was high or moderate for some behavioural and nonpharmacological interventions.

Antimicrobial prescriptions in neonatal intensive care units (NICUs) represent a point of concern for the emergence of MDROs and for morbidity associated with prolonged antibiotic exposure (e.g., invasive candidiasis, necrotizing enterocolitis, and late-onset sepsis). Antimicrobial stewardship programs (ASPs) have shown to be a valuable tool for the prevention of resistance with the goals of optimizing clinical outcomes while decreasing unnecessary prescribing. The most frequent ASP strategies include the correct collection and interpretation of microbiological specimens, prescription of the narrowest-spectrum antibiotic appropriate for a particular case, and de-escalation or discontinuation of therapy in defined situations. A robust ASP requires everyday multidisciplinary collaboration between ID physicians, neonatologist, clinical pharmacists, clinical microbiologists, infection control professionals, hospital epidemiologists, and information services specialists. Education and clinical pathways (e.g., sepsis or surgical prophylaxis pathways) are an excellent starting point if followed by proactive interventions such as prospective audits and feedback and formulary restriction with prior antimicrobial authorization. The current review outlines the problems faced in NICU antimicrobial prescribing and presents various solutions from the literature.

ETHNOPHARMACOLOGICAL RELEVANCE: The leaves of Syzygium cumini (L.) or Skeels (Myrtaceae) are widely used in Brazilian folk medicine to treat diabetes. AIM OF THE STUDY: The present study evaluated the functional capacity, biochemical parameters, oxidative stress and DNA damage from eight weeks of intervention with a crude hydroalcoholic extract of S. cumini leaves (EBH) and continuous aerobic training (TAC) in diabetic (D) rats. MATERIALS AND METHODS: A hydroalcoholic (50%) extract was prepared by ultrasound and phytochemical parameters (total phenols, total tannins and myricetin content) were analyzed. Thirty-seven male Wistar rats were divided into five groups: normoglycemic controls (CONT), diabetic controls (D-CONT), diabetics treated with extract (D+EBH), trained diabetic (D+TAC) and diabetics treated with extract and trained (D+EBH+TAC). Functional capacity was assessed with a maximum exercise capacity test; biochemical parameters with enzymatic kits; oxidative stress by superoxide dismutase (SOD), catalase (CAT), thiobarbituric acid reactive substances (TBARS) and oxidized dichlorofluorescein (DCF), and the DNA damage by the comet assay. RESULTS: The D+TAC and D+EBH+TAC groups showed better functional capacity at the end of interventions. The D+EBH group showed glucose and triglyceride reduction, lowest DNA damage index in the blood, liver, kidney, heart, lung and gastrocnemius muscle, improved SOD levels in the liver, kidney and lung, improved CAT levels in the kidney and lower lipid peroxidation in all tissues studied, compared to the D-CONT group. The exercise (D+TAC) was effective in reducing triglycerides, improving SOD levels in the lung, reducing lipid peroxidation in all tissues studied and reducing the DCF oxidation in the kidney, in addition to protecting against DNA damage in the blood and heart. However, the additive effect of the intervention protocols when combined (EBH+TAC) was observed only in improving the gastrocnemius SOD levels. The phytochemical analyses showed a high content of phenols and the presence of myricetin glycosides. CONCLUSION: The findings in this study suggest a crude hydroalcoholic extract of S. cumini leaves has potential hypoglycemic, hypolipidemic and protective properties acting against oxidative stress and against DNA damage, probably due to its phenols and myricetin glycoside content and the antioxidant properties of these constituents. Moreover, exercise was suggested to have beneficial effects on diabetes, improving functional capacity, ameliorating blood triglyceride control and decreasing lipid peroxidation, but with no effects on ameliorating blood glucose levels. The association of intervention protocols presented an additive effect on the antioxidant SOD activity in the muscle cells of diabetic rats.

BACKGROUND: Therapeutic drug monitoring is a powerful strategy known to improve the clinical outcomes and to optimise the healthcare resources in the treatment of autoimmune diseases. Currently, most of the methods commercially available for the quantification of infliximab (IFX) are ELISA-based, with a turnaround time of approximately 8 h, and delaying the target dosage adjustment to the following infusion. AIM: To validate the first point-of-care IFX quantification device available in the market - the Quantum Blue Infliximab assay (Buhlmann, Schonenbuch, Switzerland) - by comparing it with two well-established methods. METHODS: The three methods were used to assay the IFX concentration of spiked samples and of the serum of 299 inflammatory bowel diseases (IBD) patients undergoing IFX therapy. RESULTS: The point-of-care assay had an average IFX recovery of 92%, being the most precise among the tested methods. The Intraclass Correlation Coefficients of the point-of-care IFX assay vs. the two ELISA-based established methods were 0.889 and 0.939. Moreover, the accuracy of the point-of-care IFX compared with each of the two reference methods was 77% and 83%, and the kappa statistics revealed a substantial agreement (0.648 and 0.738). CONCLUSIONS: The Quantum Blue IFX assay can successfully replace the commonly used ELISA-based IFX quantification kits. This point-of-care IFX assay is able to deliver the results within 15 min makes it ideal for an immediate target concentration adjusted dosing. Moreover, it is a user-friendly desktop device that does not require specific laboratory facilities or highly specialised personnel.

Electroacupuncture (EA) has been used to treat many diseases, including heart failure (HF). This study aimed to evaluate the effects of chronic stimulation in the ST36 acupuncture point on haemodynamic parameters and baroreflex function in rats with HF. Cardiovascular parameters assessed were heart rate (HR), blood pressure (BP), and the reflex cardiovascular response of HR triggered by stimulation of baroreceptors in animals with HF subsequent to acute myocardial infarction (AMI). Male Wistar rats were divided into three groups: Sham Control - animals without HF and without EA; HF Control group - animals with HF and without EA; and HF EA group - animals with HF that received the EA protocol. Six weeks after surgical induction of AMI, the EA protocol (8 weeks, 5 times a week) was performed. The protocol was applied with EA at the ST36 point, frequency of 2 Hz, pulse of 0.3 ms and intensity of 1-3 mA for 30 min. Haemodynamic parameters and baroreceptor function were assessed. There was no difference between groups in the variables HR, systolic blood pressure (SBP) and diastolic blood pressure (DBP), which were evaluated with awake animals (p>0.05). There was an increase in the mean arterial pressure (MAP) in the HF EA group compared to the HF Control group (p<0.05). The maximum gain of the baroreflex heart rate response (Gain) was higher in the HF EA group than the HF Control and Sham Control groups. Chronic EA in the ST36 point increased the MAP and baroreflex sensitivity in rats with HF.

BACKGROUND: CDH is a major birth defect, characterized by high mortality. How the initial defective mesenchymal substructures affects muscle malformation is unclear. Defects of genes involved in diaphragmatic development, such as friend-of-GATA2 (Fog2), may play an important role in its pathogenesis. We investigated the expression of Fog2 and proteins of myogenesis in a series of CDH and in diaphragms at different fetal ages, in order to clarify the role of muscular components during diaphragmatic development in cases with CDH. MATERIAL AND METHODS: Specimen were obtained from seven diaphragms of CDH cases undergoing surgery, 3 entire diaphragms from non repaired CDH, 5 control diaphragms at different gestational ages (16, 17, 22, 32, and 40g.w.), and 3 biopsy samples of normal voluntary muscle. The thickness of diaphragms at the edge of the defect in CDH and in developing diaphragms was measured. All samples were processed for HE staining and immunohistochemistry. Immunohistochemical expression of MyoD, Myf4, Pax7, Mib1 and Fog2 was evaluated. RESULTS: Mean thickness at the edge of the defect was 4.14mm. Contralateral hemi-diaphragm in 3 autopsies and in controls at 32 and 40weeks measured 2.25mm; histology showed a higher density of desmin-positive muscular cells at the edge of defect. CDH displayed scattered Myf4-positive cells (range 0%-10%, mean 2.4%), numerous Pax7-positive cells (range 0%-24%, mean 12.1%) and less than 1% Mib1-positive cells. Controls showed a reduction of positive cell with the progression of gestational age for Myf4 (30% at 16 weeks, 20% at 17 weeks, 5% at 22 weeks, 1% at 32 and 40 weeks), Pax7 (85% at 16 weeks and 17 weeks, 35% at 22 weeks, 11% at 32 weeks) and Mib1 (20% at 16 weeks, 8% at 17 weeks, 7% at 22weeks, 2% at 32 weeks). Fog-2 was diffusely positive in mesenchymal, mesothelial and muscular cells, in diaphragms from 16 to 22 weeks, decreasing to 20% of positive muscular cells in 32-week diaphragm. In CDH only mesothelial and mesenchymal cells were positive. Stem cell markers were negative in cases and controls. COMMENT: CDH shows a thick muscular border, with high number of mature muscle cells and significant increase of quiescent satellite cells (PAX7+, Mib1-). Abnormal architecture may affect the normal process of myogenesis and thus signaling and cell-cell interactions of myocytes. The expression of Fog2 in mesothelial and mesenchymal cells in CDH demonstrates the absence of a genetic defect involving Fog2 in our cases. Being Fog2 expressed in muscle cells at early stage supports the hypothesis that the altered diaphragmatic genesis may undermine also the muscular component instead of the only mesenchymal one.

The rat posterodorsal medial amygdala (MePD) links emotionally charged sensory stimuli to social behavior, and is part of the supramedullary control of the cardiovascular system. We studied the effects of microinjections of neuroactive peptides markedly found in the MePD, namely oxytocin (OT, 10 ng and 25 pg; n=6/group), somatostatin (SST, 1 and 0.05 μM; n=8 and 5, respectively), and angiotensin II (Ang II, 50 pmol and 50 fmol; n=7/group), on basal cardiovascular activity and on baroreflex- and chemoreflex-mediated responses in awake adult male rats. Power spectral and symbolic analyses were applied to pulse interval and systolic arterial pressure series to identify centrally mediated sympathetic/parasympathetic components in the heart rate variability (HRV) and arterial pressure variability (APV). No microinjected substance affected basal parameters. On the other hand, compared with the control data (saline, 0.3 µL; n=7), OT (10 ng) decreased mean AP (MAP50) after baroreflex stimulation and increased both the mean AP response after chemoreflex activation and the high-frequency component of the HRV. OT (25 pg) increased overall HRV but did not affect any parameter of the symbolic analysis. SST (1 μM) decreased MAP50, and SST (0.05 μM) enhanced the sympathovagal cardiac index. Both doses of SST increased HRV and its low-frequency component. Ang II (50 pmol) increased HRV and reduced the two unlike variations pattern of the symbolic analysis (P<0.05 in all cases). These results demonstrate neuropeptidergic actions in the MePD for both the increase in the range of the cardiovascular reflex responses and the involvement of the central sympathetic and parasympathetic systems on HRV and APV.

OBJECTIVE: To ascertain the extent to which neonatal analgesia for invasive procedures has changed in the last 5 years since the publication of Italian guidelines. METHODS: We compared survey data for the years 2004 and 2010 on analgesia policy and practices for common invasive procedures at Italian Neonatal Intensive Care Units (NICUs); 75 NICUs answered questionnaires for both years and formed the object of this analysis. RESULTS: By 2010 analgesia practices for procedural pain had improved significantly for almost all invasive procedures (p < 0.05), both non-pharmacological and pharmacological methods being adopted by the majority of NICUs (unlike the situation in 2004). The routine use of medication for major invasive procedures was still limited, however (35% of lumbar punctures, 40% of tracheal intubations, 46% during mechanical ventilation). Postoperative pain treatment was still inadequate, and 41% of facilities caring for patients after surgery did not treat pain routinely. Pain monitoring had definitely improved since 2004 (p < 0.05), but not enough: only 21% and 17% of NICUs routinely assess pain during mechanical ventilation and after surgery, respectively. CONCLUSION: There have been improvements in neonatal analgesia practices in Italy since national guidelines were published, but pain is still undertreated and underscored, especially during major invasive procedures. It is mandatory to address the gap between the recommendations in the guidelines and clinical practice must be addressed through with effective quality improvement initiatives.

Interleukin (IL) 10 and interferon-gamma (IFN-) levels in induced sputum supernatants of 21 tuberculosis (TB) patients at diagnosis and during chemotherapy were correlated to recurrence rates. IL-10 decreased until day 60 of treatment (T60), and between T60 and T180 it increased again in 7 cases (Pattern 1) and further decreased in 14 cases (Pattern 2). Follow-up of 69 months was performed in 20/21 cases; 6 had recurrence of TB, of which 5/7 (71%) had Pattern 1 and 1/13 (7.7%) Pattern 2 (OR 30.0, 95%CI 2.19411.3, P 0.0072). This was not observed for IFN-. High IL-10 levels at the end of treatment may function as a risk factor for TB recurrence.

Endotracheal intubation is frequently performed in neonatal intensive care. This procedure is extremely distressing and painful, and it has the potential for causing laryngospasm, hemodynamic changes, a rise in intracranial pressure and a risk of hemorrhage and airway injury. These adverse changes can be attenuated by using premedication with analgesic, sedative and muscle-relaxant drugs. Premedication is standard practice for pediatric and adult Intubation, but in neonates the use of supportive pharmacological measures is still hotly debated, mainly in terms of the risks and benefits of using sedatives in unstable and premature newborn. In a recent UK survey, 90% of tertiary neonatal units reported the routine use of sedation prior to intubation with a combination of atropine plus an opioid (morphine or fentanyl), while 82% of such units routinely use a muscle-relaxant. In Italy, a recent survey (in press) showed that the majority of NICU (Neonatal Intensive Care Units) use the sa me association of drugs for analgesia and sedation before tracheal intubation, but "not always" in more than half of these units. There is clearly a persistent concern about using such drugs in preterm and newborn infants, despite recent evidence showing that premedication for elective neonatal intubation is safer and more effective than when the infant is awake. Here we review the effects of using analgesic and sedative drugs on intubation conditions (good jaw relaxation, open and immobile vocal cord, suppression of pharyngeal and laryngeal reflex), on the time it takes to complete the procedure successfully, on pain control and the potentially adverse effects of using combinations of drugs for sedation.

OBJECTIVE: Endoanal ultrasonography can detect organic causes of anal pain without pathology on physical examination. The aim of this study is to evaluate the importance of endoanal ultrasonography in the diagnosis and therapeutic management of idiopathic and functional anal pain. MATERIAL AND METHODS: Retrospective study, between 15 March 2005 and 15 June 2008, of all patients with proctalgia and normal examination or with alterations not responsible for anal pain at proctologic exam that have undergone an endoanal ultrasonography. RESULTS: A total of 90 patients were analyzed, with a mean age of 50.5 years, 58% were female. Twenty-three patients had functional anal pain clinic criteria. Endoanal ultrasonography revealed alterations in 49% of patients. The primary findings were changes in sphincters in 14 patients, followed by anal sepsis in 12 patients, anal fissure in 10 patients, perirectal lesions in 6 patients and ulcer of the anal canal in 2 patients. Of the patients with sphincter defects, 5 patients had criteria of chronic anal pain. In this group of patients, no differences were found in manometric and defecographic results between the different ultrasound abnormalities. CONCLUSIONS: The endoanal ultrasonography detected occult organic lesions to proctologic examination, in half the patients with anal pain. Ultrasound abnormalities were found in 22% of patients with functional anal pain. However, there was no correlation between ultrasound findings and physiological studies, and therefore could not find etiological or pathogenic factors of functional anal pain.

PURPOSE: To estimate inflammatory bowel disease (IBD) prevalence in Portugal from 2003 to 2007, and to obtain disease, sex and age specific estimates. METHODS: A pharmaco-epidemiological approach based on intestinal anti-inflammatory (IAI) drugs consumption was used. Proportion of patients taking IAI drugs and mean prescribed daily dose (PDD) were estimated from a sample of 513 IBD patients. Assumptions were made about unknown parameters and sensitivity analysis performed: drug compliance (80% in base case; range 70-85%) and proportion of sulphasalazine used in IBD (52%; range 40-80%). Sex and age specific estimates were based on a proposed methodological extension and results from a nationwide (n = 5893) cross-sectional study. RESULTS: IBD prevalence increased from 86 patients per 100 000 in 2003 to 146 in 2007. Regions more affected were Lisboa and Porto (173 and 163 per 100 000 in 2007, respectively). Prevalence increased from 42 and 43 per 100 000 in 2003 to 71 and 73 in 2007, respectively for ulcerative colitis (UC) and Crohn's disease (CD). In 2007, prevalence was higher in the 40-64 age stratum for UC (99 per 100 000) and in the 17-39 stratum for CD (121). Prevalence was consistently higher in females. CONCLUSIONS: Portugal is half way between countries with the highest and lowest IBD prevalence, but is steeply making the road to the highest-level group. Despite limitations of the proposed methods, assumptions were reasonable and estimates seem to be valid. Feasibility and comparability of this methodology makes it an interesting tool for future studies on IBD epidemiology.
