The role of the Sapienza GLObal Bedside Evaluation of Swallowing after Stroke (GLOBE-3S) in the prevention of stroke-associated pneumonia (SAP).

BACKGROUND AND PURPOSE: Stroke-associated pneumonia (SAP) affects 10 to 38% of patients in the acute phase of stroke. Stroke patients diagnosed with dysphagia have an 11-fold higher risk of developing SAP. Thus, identifying dysphagic patients through a highly accurate screening tool might be crucial in reducing the incidence of SAP. We present a case-control study designed to evaluate efficacy in reducing the risk of SAP between two swallowing screening tools, the classic water swallow test (WST) and a recently validated tool such as the GLOBE-3S (the Sapienza GLObal Bedside Evaluation of Swallowing after Stroke), which is a highly sensitive swallowing screening tool particularly accurate in detecting silent aspiration as well. METHODS: We analyzed the occurrence of dysphagia in 100 acute stroke patients distributed in two groups: half were screened with WST and the other half with GLOBE-3S. RESULTS: Dysphagia was diagnosed in 28 patients. The main result is that, among patients who passed the dysphagia screenings, none of those screened with the GLOBE-3S method developed pneumonia compared to 31.82% in the WST group. Discriminant function analysis (DFA) showed that NIH Stroke Scale (NIHSS) score and the dysphagia screening method (i.e., GLOBE-3S vs. WST) were the two main factors in the SAP's predicting model and the only significant ones per se. CONCLUSIONS: The new GLOBE-3S screening test can reduce the risk of SAP compared to WST.

Full robotic Hartmann's reversal: technical aspects and preliminary experience.

AIM: Laparoscopic Hartmann's reversal (HR) is a major abdominal operation that is associated with considerable morbidity and mortality. The robotic approach, with its intrinsic advantages, could potentially overcome the technical complexity of laparoscopy. The aim of this study was to evaluate the short-term results of a series of 24 robotic HR cases. METHOD: The data from 24 patients who underwent robotic HR between September 2016 and July 2019 at two different institutions were prospectively collected and retrospectively analysed. A full robotic single-docking reversal procedure with intracorporeal anastomosis was performed in all patients. RESULTS: The mean age and body mass index of the patients were 69 years and 26 kg/m2 , respectively. Of the patients, 58% were ≥ 70 years old and 42% had comorbidities (mean Charlson Comorbidity Index 3). The mean operating time was 240 min. There were no cases of conversion to the open or laparoscopic approach. No diverting loop ileostomies were constructed. The mean length of hospital stay was 6 days. Minor complications were recorded in three patients. Neither major complications nor 30-day readmissions were registered. CONCLUSIONS: Robotic HR is a feasible and safe procedure. The robotic approach has low rates of major complications and conversion and could potentially increase the number of patients undergoing HR.

Sapienza Global Bedside Evaluation of Swallowing after Stroke: the GLOBE-3S study.

BACKGROUND AND PURPOSE: Dysphagia occurs in up to 50% of all patients with acute stroke. There is debate regarding which is the most effective screening tool in identifying aspiration in patients with acute stroke. We assessed the accuracy of the Sapienza Global Bedside Evaluation of Swallowing after Stroke (GLOBE-3S), which combines the Toronto Bedside Swallowing Screening Test (TOR-BSST©) with oxygen desaturation and laryngeal elevation measurement during swallowing. METHODS: We prospectively enrolled consecutive patients with stroke within 72 h of symptom onset. All patients with stroke firstly underwent a standard neurological examination, then the GLOBE-3S evaluation and finally the fiberoptic endoscopic evaluation of swallowing (FEES). Two different assessors, a neurologist and a speech pathologist, blind to both the clinical data and each other's evaluation, administered the GLOBE-3S and FEES examination. We assessed the accuracy of the GLOBE-3S in detecting post-stroke swallow impairment with aspiration using the FEES as the standard. RESULTS: We enrolled 50 patients with acute stroke, 28 of whom (56%) had swallowing impairment with aspiration at FEES evaluation. A total of 33 patients (66%) failed the GLOBE-3S evaluation. The GLOBE-3S reached a sensitivity of 100% and a specificity of 77.3% (negative predictive value, 100%; positive likelihood ratio, 4.34). The median time required for the GLOBE-3S to be performed was 297 s. CONCLUSIONS: GLOBE-3S is quick to perform at the bedside and can accurately identify aspiration in patients with acute stroke. By including the measurement of laryngeal elevation and monitoring of oxygen desaturation, it could represent a highly sensitive instrument to avoid the misdiagnosis of silent aspirators.

Essential strategies in HAI prevention and control: performance assessment through the implementation of the HAI-CoSIP tool of the GISIO-SItI group. A pilot study in a sample of Italian Organizations.

BACKGROUND: Healthcare-Associated Infections are a great concern for worldwide healthcare systems and represent a considerable threat to patient safety, leading to adverse clinical outcomes. A defined panel of indicators represents a key element to guide Healthcare Organizations towards identification of main gaps, implementation of effective actions and continuous improvements on Healthcare-Associated Infections prevention and control activities. A review on accreditation systems conducted by the Italian Study Group of Hospital Hygiene of the Italian Society of Hygiene Preventive Medicine and Public Health revealed a substantial heterogeneity of implemented standards and led to the development of a core set of indicators and requirements for Healthcare-Associated Infections' prevention and control within the hospital setting. The main aim of the study was to test the feasibility of the Healthcare-Associated Infections' prevention and control within the hospital setting tool to calculate performance scores on a sample of Italian Healthcare Organizations and to identify major critical issues. The potential benefits of the possibility of future implementation of the tool within Institutional Accreditation Programs is discussed. STUDY DESIGN: Cross sectional pilot survey. METHODS: The Healthcare-Associated Infections' prevention and control within the hospital setting included 96 criteria and 20 key areas including an area for outcomes indicators. For applicable criteria, standards fulfilment was evaluated according to a 4 point Likert scale. A composite score was calculated for each Healthcare Organization and five performance levels were identified. Data were further analysed by computing performance scores at the level of each area and requirement. RESULTS: 20 Healthcare Organizations agreed to take part in this pilot study including two rehabilitative Healthcare Organizations. Among the whole sample a mean of 12.20% of requirements resulted not fulfilled, leaving space for further improvements. Critical areas were easily identified and the instrument was able to capture substantial differences between Healthcare Organizations. Only a few number of standards resulted "Not Applicable" (Mean = 4.71%) and most of them regarded Rehabilitative Healthcare Organizations. Mean composite performance index resulted 74.06% (SD = 16.96, range 36.30 - 94.27%); area of outcome indicators obtained a mean score of 56.17. CONCLUSION: The Healthcare-Associated Infections' prevention and control within the hospital setting resulted an useful tool to assess Healthcare Organizations' performance in the field of Healthcare-Associated Infections prevention and control and to identify necessary actions for further improvements. The distribution of total scores by Healthcare Organizations showed a high heterogeneity. Implementation of the Healthcare-Associated Infections' prevention and control within the hospital setting tool as an institutional accreditation tool may help to drive the required harmonization at a national level of Healthcare-Associated Infections management and control strategies and overcome current substantial regional differences.

Randomized clinical trial of percutaneous tibial nerve stimulation versus sham electrical stimulation in patients with faecal incontinence.

BACKGROUND: The aim was to assess the effects of percutaneous tibial nerve stimulation (PTNS) in the treatment of faecal incontinence (FI) by means of an RCT. METHODS: Patients aged over 18 years with FI were included in a multicentre, single-blinded RCT. The primary endpoint was reduction in the median or mean number of FI episodes per week. Secondary endpoints were changes in measures of FI severity, and disease-specific and generic quality of life. Outcomes were compared between PTNS and sham stimulation after 9 weeks of treatment. RESULTS: A higher proportion of patients in the PTNS (13 of 29) than in the sham (6 of 30) group showed a reduction of at least 50 per cent in the median number of FI episodes/week (incidence rate ratio (IRR) 2·40, 95 per cent c.i. 1·10 to 5·24; P = 0·028), but not in the mean number of episodes/week (10 of 29 versus 8 of 30; IRR 1·42, 0·69 to 2·92; P = 0·347). The absolute median number of FI episodes per week decreased in the PTNS but not in the sham group (IRR 0·66, 0·44 to 0·98; P = 0·041), as did the mean number (IRR 0·65 (0·45 to 0·97); P = 0·034). Scores on the Cleveland Clinic Florida faecal incontinence scale decreased significantly in both groups, but more steeply in the PTNS group (mean difference -1·3, 95 per cent c.i. -2·6 to 0·0; P = 0·049). The aggregated mental component score of Short Form 36 improved in the PTNS but not in the sham group (mean difference 5·1, 0·5 to 9·6; P = 0·028). CONCLUSION: PTNS may offer a small advantage in the clinical management of FI that is insufficiently responsive to conservative treatment. The key challenge will be to identify patients who may benefit most from this minimally invasive surgical procedure. Registration number: NCT00974909 (http://www.clinicaltrials.gov).

Definition of criteria and indicators for the prevention of Healthcare-Associated Infections (HAIs) in hospitals for the purposes of Italian institutional accreditation and performance monitoring.

BACKGROUND: Healthcare-associated infections (HAIs) are an important issue in terms of quality of care. HAIs impact patient safety by contributing to higher rates of preventable mortality and prolonged hospitalizations. In Italy, analysis of the currently available accreditation systems shows a substantial heterogeneity of approaches for the prevention and surveillance of HAIs in hospitals. The aim of the present study is to develop and propose the use of a synthetic assessment tool that could be implemented homogenously throughout the nation. METHODS: An analysis of nine international and of the 21 Italian regional accreditation systems was conducted in order to identify requirements and indicators implemented for HAI prevention and control. Two relevant reviews on this topic were further analyzed to identify additional evidence-based criteria. The project team evaluated all the requirements and indicators with consensus meeting methodology, then those applicable to the Italian context were grouped into a set of "focus areas". RESULTS: The analysis of international systems and Italian regional accreditation manuals led to the identification respectively of 19 and 14 main requirements, with relevant heterogeneity in their application. Additional evidence-based criteria were included from the reviews analysis. From the consensus among the project team members all the standards were compared and 20 different thematic areas were identified, with a total of 96 requirements and indicators for preventing and monitoring HAIs. CONCLUSIONS: The study reveals a great heterogeneity in the definition of accreditation criteria between the Italian regions. The introduction of a uniform, synthetic assessment instrument, based on the review of national and international standards, may serve as a self-assessment tool to evaluate the achievement of a minimum standards set for HAIs prevention and control in healthcare facilities. This may be used as an assessment tool by the Italian institutional accreditation system, also useful to reduce regional disparities.

Repair of transperineal recto-urethral fistula using a fibrin sealant haemostatic patch.

AIM: Recto-urethral fistula (RUF) is a rare complication of radical prostatectomy. We report a transperineal approach using a fibrin sealant haemostatic patch. METHOD: Five consecutive patients who developed RUF following radical prostatectomy had a direct transperineal repair with a haemostatic patch (TachoSil®) and were assessed at a median follow-up of 35.5 (21-45) months. RESULTS: There were no early postoperative complications. The average length of hospital stay was 5 (4-7) days. One patient developed recurrence 4 weeks after removal of the urethral catheter. Following healing in four patients the stoma was reversed at a median interval of 3 months, and 9.5 (7-10) months following the prostatic surgery. In the four patients with successful closure there was no case of recurrence or anorectal or urinary dysfunction at a median follow-up of 35.5 (21-45) months. CONCLUSION: Direct transperineal repair of RUF reinforced with a fibrin haemostatic patch of TachoSil is safe and effective.

Two-dimensional tomographic terahertz imaging by homodyne self-mixing.

We realize a compact two-dimensional tomographic terahertz imaging experiment involving only one photoconductive antenna (PCA) simultaneously serving as a transmitter and receiver of the terahertz radiation. A hollow-core Teflon cylinder filled with α-Lactose monohydrate powder is studied at two terahertz frequencies, far away and at a specific absorption line of the powder. This sample is placed between the antenna and a chopper wheel, which serves as back reflector of the terahertz radiation into the PCA. Amplitude and phase information of the continuous-wave (CW) terahertz radiation are extracted from the measured homodyne self-mixing (HSM) signal after interaction with the cylinder. The influence of refraction is studied by modeling the set-up utilizing ZEMAX and is discussed by means of the measured 1D projections. The tomographic reconstruction by using the Simultaneous Algebraic Reconstruction Technique (SART) allows to identify both object geometry and α-Lactose filling.

Long-term evaluation of bulking agents for the treatment of fecal incontinence: clinical outcomes and ultrasound evidence.

BACKGROUND: The injection of bulking agents into the anal canal has been reported to help patients with fecal incontinence. Although it has been advocated as a safe and effective option, substantial data concerning long-term efficacy are still lacking, and the resorption process of the implants has not yet been carefully studied. The aim of our study was to investigate the long-term outcomes of bulking agents for the treatment of fecal incontinence and the behavior of implanted materials in the anorectum. METHODS: At a median follow-up of 7 years, 19 patients with idiopathic fecal incontinence who had received bulking agent implants were evaluated. Clinical, manometric and ultrasound assessments were carried out. RESULTS: The clinical improvements that were achieved in the short term were not maintained over time. For each patient, the number of implants that could no longer be identified on ultrasound was significantly correlated with poorer clinical long-term outcomes. On average, only 14% of the originally injected volume was still detectable. CONCLUSIONS: In the long term, perianally injected bulking agents seem to lose effectiveness. The ultrasound assessment suggests that the process of resorption is almost complete, and the implants are no longer effective in treating incontinence.

Renal tuberculosis: a case report.

Tuberculosis or TB (tubercle bacillus) remains a major public health problem in developing countries. Over the last decades extrapulmonary locations of the disease have become more frequent due to the increased prevalence of acquired immune deficiency syndrome and the increase number of organ transplants. The urogenital localization represents about 27% of all extra-pulmonary localizations of TB and may be due either to a disseminated infection or to a primitive genitourinary localization. The majority of patients, has pyuria, sometimes with hematuria. The diagnosis of urinary tuberculosis is based on the finding of pyuria in the absence of infection by common bacteria. The initial medical treatment includes isoniazide, rifampicin, pyrazinamide, ethambutol and streptomycin. This disease should be suspected in patients with unexplained urinary tract infections, especially if immunocompromised and/or coming from endemic areas.

Natalizumab treatment in multiple sclerosis patients: a multicenter experience in clinical practice in Italy.

We evaluated efficacy of natalizumab in relapsing-remitting multiple sclerosis patients in a clinical practice setting. We report data on the first consecutive 343 patients receiving natalizumab in 12 multiple sclerosis (MS) Italian centers enrolled between April 2007 and November 2010. The main efficacy endpoints were the proportion of patients free from relapses, disease progression, combined clinical activity, defined as presence of relapse or disease progression, from MRI activity, and from any disease activity defined as the absence of any single or combined activity. At the end of follow-up, the cumulative proportion of patients free from relapses was 68%; the proportion of patients free from Expanded Disability Status Scale (EDSS) progression was 93%; the proportion of patients free from combined clinical activity was 65%; the proportion of patients free from MRI activity was 77%; and the proportion of patients free from any disease activity was 53%. Natalizumab was effective in reducing clinical and neuroradiological disease activity. Its effectiveness in clinical practice is higher than that reported in pivotal trials and was maintained over time.

Control of post-hemorrhoidectomy symptoms and wound healing by Triclosan: a randomized, double-blind, controlled trial.

AIM: Milligan-Morgan hemorrhoidectomy (MM) is still the most common treatment for grades III and IV hemorrhoids despite prolonged post-operative anal pain and wound healing. This multicenter, double blind, randomized, controlled trial was designed to assess the safety and the efficacy of anal wound cleansing with Triclosan (Proctocid®) in the control of symptoms and healing time after MM. METHODS: A total of 113 patients with grades III and IV hemorrhoids, undergoing open hemorroidectomy by diathermy or Ligasure vessel sealing device, were randomly assigned to Triclosan or sodium hypochlorite solution. All patients received analgesics and a fiber-rich diet after hemorrhoidectomy. Postoperative anal pain, bleeding and/or secretion and itch were assessed 7, 14 and 21 days after hemorrhoidectomy by a Visual Analogue Scale (VAS) and the day of complete re-epithelialization of anal wounds was recorded. RESULTS: Fifty-five patients were randomized for Triclosan treatment and 58 for the control drug. The two groups were comparable for demographics, severity of hemorrhoids and technique used for the hemorrhoidectomy. The comparison of days to get complete anal wound healing shows a trend of significance (P=0.05) for the Triclosan group. Bleeding and/or secretion, anal pain and itch were significantly better (P=0.003; P<0.0001 and P=0.01, respectively). CONCLUSION: Triclosan solution for the treatment of post-hemorrhoidectomy wounds is safe and improves the control of post-operative symptoms and wound healing time compared to sodium hypochlorite.

Non-palpable breast lesions localization techniques - A new priority: Results of a Senonetwork survey among breast centers in Italy.

INTRODUCTION: Non palpable breast tumors are increasingly diagnosed because of screening programs, and their localization during surgery is essential to ensure an adequate resection. Little is known regarding which techniques are used in "real world". MATERIALS AND METHODS: A national web-based survey, with a 21-items questionnaire, was conducted among Breast Centers (BCs) in Italy in 2023. RESULTS: Among 153 BCs, 110 (72 %) participated. Wire-guided localization was reported to be the most used technique, regardless of the volume of malignant tumors treated by each Center (N = 36, 33 %). However, newer techniques such as Radioactive occult lesion localization and magnetic seeds, were reported to be employed in 34 (31 %) BCs, and more often among high-volume BCs (>300 cases/year) (N = 32, 29 % vs. N = 13, 12 %; p = 0.02). Logistic problems of localization were reported to cause delays to the scheduled surgery at least once or in multiple occasions in 26 (24 %) and in 4 (3.5 %) BCs, respectively. Although the majority of BCs declared they were satisfied (N = 48, 44 %) or somewhat satisfied (N = 41, 37 %) with the procedure used in their center, responders stated that they would change their technique, or that they were strongly considering this possibility in 24 (22 %) and in 38 (35 %) cases, respectively. The main barrier to introducing a new technique was associated with procedure costs (90 BCs, 82 %). CONCLUSIONS: There are several critical issues regarding localization techniques at a national level. This should be recognized as a priority because of its impact on both patients and clinical practices.

Measurement of the plasma astrophysical S factor for the 3He(d,p)4He reaction in exploding molecular clusters.

The plasma astrophysical S factor for the 3He(d,p)4He fusion reaction was measured for the first time at temperatures of few keV, using the interaction of intense ultrafast laser pulses with molecular deuterium clusters mixed with 3He atoms. Different proportions of D2 and 3He or CD4 and 3He were mixed in the gas target in order to allow the measurement of the cross section for the 3He(d,p)4He reaction. The yield of 14.7 MeV protons from the 3He(d,p)4He reaction was measured in order to extract the astrophysical S factor at low energies. Our result is in agreement with other S factor parametrizations found in the literature.

Fluctuations of MS births and UV-light exposure.

BACKGROUND: Patients with multiple sclerosis (MS) are more frequently born in spring when compared to autumn. Fluctuation of UV-light has been hypothesized to drive this phenomenon. AIM: To assess the correlation between fluctuation of sunlight and birth season in persons with MS. METHODS: For this record-linkage study, we collected from the international MSBase and the Italian MS iMed-web databases the dates of birth of 11,415 patients with MS from 36 centres from 15 countries worldwide and compared these to dates of live-births from national registries. From all participating sites, we collected data on UV-light fluctuation and assessed its correlation with seasonal fluctuation in MS births. RESULTS: Compared with the reference cohort, an increased proportion of persons with MS were born in spring and a decreased proportion in autumn (odds ratio (OR) to be born in spring versus autumn = 1.158, χ² = 36.347, P < 0.001). There was no significantly increased fluctuation of MS births with increased quartile of ambient UV-light fluctuation (Ptrend = 0.086). CONCLUSION: Seasonal fluctuation of MS births as found in this worldwide cohort of patients with MS did not correlate with variation in seasonal fluctuation of UV-light. Most likely, it results from a complex interplay between fluctuation of sunlight, behavioural factors, other environmental factors and (epi)genetic factors.

Pesticide residue free fruits: the aim of Trentino apple production system.

Chemical analyses performed in 2011 on the 575 samples of apples in Trentino (Italy), there are in average 3.24 active ingredient per sample. Moreover, in 98% of the samples with detectable residues, the level did not exceed 30% of the official MRL This result is achieved thanks to the implementation of the guide lines for integrated production by the 8000 fruit growers, to an extension service which justifies the need of the treatment and gives advice on which pesticide fit better for the time-pest combination, to the systematic check up of the sprayers, to the correct sizing of mix volumes to spray according to the size of the canopy, to the selection of active ingredients based on their residual activity in field tests, and to the systematic monitoring of the level of residues found on representative samples of the product at harvest. With these assumptions, the next goal is to eliminate all traces of insecticides and acaricides now present only in 30% of the samples. This aim could be achieved by extending the use of pheromone mating disruption to control fruit feeding Lepidoptera, as well as by promoting the use of short persistent residue products during the final part of the season. Results of some of the experimental field trials are presented and discussed.

The frequency of CSF oligoclonal banding in multiple sclerosis increases with latitude.

BACKGROUND: With the advent of MRI scanning, the value of lumbar puncture to assess oligoclonal band (OCB) status-for the diagnosis of multiple sclerosis (MS) is increasingly uncertain. One major issue is that the reported frequency of cerebrospinal fluid (CSF)-restricted oligoclonal banding for the diagnosis of MS varies considerably in different studies. In addition, the relationship between OCB positivity and disease outcome remains uncertain, as reported studies are generally too small to assess comparative disability outcomes with sufficient power. METHODS: In order to further investigate variation of OCB positivity in patients with MS, we utilized MSBase, a longitudinal, Web-based collaborative MS outcomes registry following clinical cohorts in several continents and latitudes. We also assessed whether OCB positivity affects long-term disability outcome. RESULTS: A total of 13,242 patient records were obtained from 37 MS specialist centres in 19 different countries. OCB status was documented in 4481 (34%) patients and 80% of these were OCB positive. The presence of OCB was associated with degree of latitude (p = 0.02). Furthermore, the outcome of patients negative for CSF-specific OCB was significantly better in comparison to the OCB positive patients, as assessed by Expanded Disability Status Scale change (p < 0.001). CONCLUSIONS: The results of this study indicate that latitude could explain some of the inconsistencies in OCB status reported in different populations. The study confirms that OCB positivity in MS is associated with a worse long-term prognosis.

Promptness of diagnosis is the main prognostic factor after colonoscopic perforation.

AIM: The authors present their experience of colonoscopic perforation and its management, with an analysis of factors affecting outcome. METHOD: During the last 10 years, 22 cases of colonoscopic perforation (CP) were identified in two different institutions. Multiple logistic regression analysis was used to identify significant predictors of morbidity and mortality. RESULTS: Morbidity and mortality rates were 31% and 13.6%, respectively. Prompt diagnosis was the most powerful predictor of outcome of CP. Multiple logistic regression analysis showed that morbidity and mortality were significantly related to a delay in diagnosis of more than 24 h (P = 0.03 and P = 0.04). CONCLUSION: The results emphasize the importance of prompt assessment of a patient who develops symptoms after colonoscopy.
