RESUMO

BACKGROUND: Efficient ventilation is important during cardiopulmonary resuscitation (CPR). Nevertheless, there is insufficient knowledge on how the patient's position affects ventilatory parameters during mechanically assisted CPR. We studied ventilatory parameters at different positive end-expiratory pressure (PEEP) levels and when using an inspiratory impedance valve (ITD) during horizontal and head-up CPR (HUP-CPR). METHODS: In this human cadaver experimental study, we measured tidal volume (VT) and pressure during CPR at different randomized PEEP levels (0, 5 or 10 cmH2O) or with an ITD. CPR was performed, in the following order: horizontal (FLAT), at 18° and then at 35° head-thorax elevation. During the inspiratory phase we measured the net tidal volume (VT) adjusted to predicted body weight (VTPBW), reversed airflow (RAF), and maximum and minimum airway pressure (Pmax and Pmin). RESULTS: Using ten thawed fresh-frozen cadavers we analyzed the inspiratory phase of 1843 respiratory cycles, 229 without CPR and 1614 with CPR. In a mixed linear model, thoracic position and PEEP significantly impacted VTPBW (p < 0.001 for each), and the insufflation time, thoracic position and PEEP significantly affected the RAF (p < 0.001 for each) and Pmax (p < 0.001). For Pmin, only PEEP was significant (p < 0.001). In subgroup analysis, at 35° VTPBW and Pmax were significantly reduced compared with the flat or 18° position. CONCLUSION: When using mechanical ventilation during CPR, it seems that the PEEP level and patient position are important determinants of respiratory parameters. Moreover, tidal volume seems to be lower when the thorax is positioned at 35°.

RESUMO

The precise monitoring of the intrapleural pressures, necessitates the development of a specific instrumental approach to select the correct shape, dimensions and material to implement the sensing balloon which will be inserted into the pleural cavity. We demonstrate that a 10 cm diameter disk, printed with filaments of TPU (Thermoplastic polyurethane) with hardness 92A offers the best compromise in terms of static sensitivity (0.28 mV/cmHg) and dynamic frequency response (48 Hz).

RESUMO

Genetic studies of familial forms of interstitial lung disease (ILD) have led to the discovery of telomere-related gene (TRG) mutations (TERT, TERC, RTEL1, PARN, DKC1, TINF2, NAF1, NOP10, NHP2, ACD, ZCCH8) in approximately 30% of familial ILD forms. ILD patients with TRG mutation are also subject to extra-pulmonary (immune-hematological, hepatic and/or mucosal-cutaneous) manifestations. TRG mutations may be associated not only with idiopathic pulmonary fibrosis (IPF), but also with non-IPF ILDs, including idiopathic and secondary ILDs, such as hypersensitivity pneumonitis (HP). The presence of TRG mutation may also be associated with an accelerated decline of forced vital capacity (FVC) or poorer prognosis after lung transplantation, notwithstanding which, usual ILD treatments may be proposed. Lastly, patients and their relatives are called upon to reduce their exposure to environmental lung toxicity, and are likely to derive benefit from specific genetic counseling and pre-symptomatic genetic testing.

RESUMO

Enterococcus faecalis is a natural inhabitant of the human gastrointestinal tract. This bacterial species is subdominant in a healthy physiological state of the gut microbiota (eubiosis) in adults, but can become dominant and cause infections when the intestinal homeostasis is disrupted (dysbiosis). The relatively high concentrations of bile acids deoxycholate (DCA) and taurocholate (TCA) hallmark eubiosis and dysbiosis, respectively. This study aimed to better understand how E. faecalis adapts to DCA and TCA. We showed that DCA impairs E. faecalis growth and possibly imposes a continuous adjustment in the expression of many essential genes, including a majority of ribosomal proteins. This may account for slow growth and low levels of E. faecalis in the gut. In contrast, TCA had no detectable growth effect. The evolving transcriptome upon TCA adaptation showed the early activation of an oligopeptide permease system (opp2) followed by the adjustment of amino acid and nucleotide metabolisms. We provide evidence that TCA favors the exploitation of oligopeptide resources to fuel amino acid needs in limiting oligopeptide conditions. Altogether, our data suggest that the combined effects of decreased DCA and increased TCA concentrations can contribute to the rise of E. faecalis population during dysbiosis.

RESUMO

PURPOSE: The Varian TrueBeam STx linac can be equipped with BrainLAB stereotactic cones and ExacTrac imaging system for SRS treatments. However, these two third-party systems lack integration in a self-performance diagnosis tool dedicated to the SRS platform. The aim of this work was to design and automate essential geometric tests considering the complete set of cones with diameter range from 4 to 15 mm. METHODS: EPID-based tests were focused on the cone alignment, the radiation isocentricity and the isocenters congruence. Images acquired with or without the BrainLAB pointer were analysed using the Hough transform and morphological filtering operations, after assessment of the algorithm accuracy using simulated images. The new Machine QA program was experimented over one year. RESULTS: A subpixel resolution of 0.02 mm was found for the circular-field center detection algorithm. The tests results did not depend on the pointer location. The maximum deviations reported were in accordance with the AAPM SRS guidelines. The accurate localization of the linac radiation isocenter allowed for guidance of the ExacTrac calibration. A misalignment reaching 0.2 mm was measured for all cones but one, highlighting the benefit of systematizing this control before each patient SRS treatment. CONCLUSION: An effective in-house QA program dedicated to SRS cones was developed to supplement the standard machine performance check on our mixed SRS platform. Specific geometric tests even include the smallest 4-mm cone, which could be of great interest for future clinical indications such as the radiosurgery of functional disorders.

RESUMO

OBJECTIVE: To assess the incidence of serious complications and reoperations for recurrence after surgery for pelvic organ prolapse (POP) and compare the three most common types of repair. DESIGN: Prospective cohort study using a registry. SETTING: Nineteen French surgical centres. POPULATION: A total of 2309 women participated between 2017 and 2019. METHODS: A multivariate analysis including an inverse probability of treatment weighting approach was used to obtain three comparable groups. MAIN OUTCOME MEASURES: Serious complications and subsequent reoperations for POP recurrence. RESULTS: The median follow-up time was 17.6 months. Surgeries were native tissue vaginal repairs (n = 504), transvaginal mesh placements (n = 692) and laparoscopic sacropexies with mesh (n = 1113). Serious complications occurred among 52 women (2.3%), and reoperation for POP recurrence was required for 32 women (1.4%). At 1 year the cumulative weighted incidence of serious complications was 1.8% for native tissue vaginal repair, 3.9% for transvaginal mesh and 2.2% for sacropexy, and the rates for reoperation for recurrence of POP were 1.5, 0.7 and 1.1%, respectively. Compared with native tissue vaginal repair, the risk of serious complications was higher in the transvaginal mesh group (weighted hazard ratio, wHR 3.84, 95% CI 2.43-6.08) and the sacropexy group (wHR 2.48, 95% CI 1.45-4.23), whereas the risk of reoperation for prolapse recurrence was lower in both the transvaginal mesh (wHR 0.22, 95% CI 0.13-0.39) and sacropexy (wHR 0.29, 95% CI 0.18-0.47) groups. CONCLUSIONS: Our results suggest that native tissue vaginal repairs have the lowest risk of serious complications but the highest risk of reoperation for recurrence. These results are useful for informing women and for shared decision making. TWEETABLE ABSTRACT: Laparoscopic sacropexy had fewer serious complications than transvaginal mesh and fewer reoperations for recurrence than vaginal repair.

RESUMO

BACKGROUND: Dynamic pulmonary hyperinflation may develop in patients with chronic obstructive pulmonary disease (COPD) due to dynamic airway collapse and/or increased airway resistance, increasing the risk of volutrauma and hemodynamic compromise. The reference standard to quantify dynamic pulmonary hyperinflation is the measurement of the volume at end-inspiration (Vei). As this is cumbersome, the aim of this study was to evaluate if methods that are easier to perform at the bedside can accurately reflect Vei. METHODS: Vei was assessed in COPD patients under controlled protective mechanical ventilation (7 ± mL/kg) on zero end-expiratory pressure, using three techniques in a fixed order: (1) reference standard (Veireference): passive exhalation to atmosphere from end-inspiration in a calibrated glass burette; (2) ventilator maneuver (Veimaneuver): measuring the expired volume during a passive exhalation of 45s using the ventilator flow sensor; (3) formula (Veiformula): (Vt × Pplateau)/(Pplateau - PEEPi), with Vt tidal volume, Pplateau is plateau pressure after an end-inspiratory occlusion, and PEEPi is intrinsic positive end-expiratory pressure after an end-expiratory occlusion. A convenience sample of 17 patients was recruited. RESULTS: Veireference was 1030 ± 380 mL and had no significant correlation with Pplateau (r2 = 0.06; P = 0.3710) or PEEPi (r2 = 0.11; P = 0.2156), and was inversely related with Pdrive (calculated as Pplateau -PEEPi) (r2 = 0.49; P = 0.0024). A low bias but rather wide limits of agreement and fairly good correlations were found when comparing Veimaneuver and Veiformula to Veireference. Vei remained stable during the study period (low bias 15 mL with high agreement (95% limits of agreement from - 100 to 130 mL) and high correlation (r2 = 0.98; P < 0.0001) between both measurements of Veireference). CONCLUSIONS: In patients with COPD, airway pressures are not a valid representation of Vei. The three techniques to quantify Vei show low bias, but wide limits of agreement.

RESUMO

BACKGROUND: The outbreak of chilblain-like lesions (CLL) during the COVID-19 pandemic has been reported extensively, potentially related to SARS-CoV-2 infection, yet its underlying pathophysiology is unclear. OBJECTIVES: To study skin and blood endothelial and immune system activation in CLL in comparison with healthy controls and seasonal chilblains (SC), defined as cold-induced sporadic chilblains occurring during 2015 and 2019 with exclusion of chilblain lupus. METHODS: This observational study was conducted during 9-16 April 2020 at Saint-Louis Hospital, Paris, France. All patients referred with CLL seen during this period of the COVID-19 pandemic were included in this study. We excluded patients with a history of chilblains or chilblain lupus. Fifty patients were included. RESULTS: Histological patterns were similar and transcriptomic signatures overlapped in both the CLL and SC groups, with type I interferon polarization and a cytotoxic-natural killer gene signature. CLL were characterized by higher IgA tissue deposition and more significant transcriptomic activation of complement and angiogenesis factors compared with SC. We observed in CLL a systemic immune response associated with IgA antineutrophil cytoplasmic antibodies in 73% of patients, and elevated type I interferon blood signature in comparison with healthy controls. Finally, using blood biomarkers related to endothelial dysfunction and activation, and to angiogenesis or endothelial progenitor cell mobilization, we confirmed endothelial dysfunction in CLL. CONCLUSIONS: Our findings support an activation loop in the skin in CLL associated with endothelial alteration and immune infiltration of cytotoxic and type I IFN-polarized cells leading to clinical manifestations.

RESUMO

Correlative light and electron microscopy (CLEM) is a method used to investigate the exact same region in both light and electron microscopy (EM) in order to add ultrastructural information to a light microscopic (usually fluorescent) signal. Workflows combining optical or fluorescent data with electron microscopic images are complex, hence there is a need to communicate detailed protocols and share tips & tricks for successful application of these methods. With the development of volume-EM techniques such as serial blockface scanning electron microscopy (SBF-SEM) and Focussed Ion Beam-SEM, correlation in three dimensions has become more efficient. Volume electron microscopy allows automated acquisition of serial section imaging data that can be reconstructed in three dimensions (3D) to provide a detailed, geometrically accurate view of cellular ultrastructure. In addition, combining volume-EM with high-resolution light microscopy (LM) techniques decreases the resolution gap between LM and EM, making retracing of a region of interest and eventual overlays more straightforward. Here, we present a workflow for 3D CLEM on mouse liver, combining high-resolution confocal microscopy with SBF-SEM. In this workflow, we have made use of two types of landmarks: (1) near infrared laser branding marks to find back the region imaged in LM in the electron microscope and (2) landmarks present in the tissue but independent of the cell or structure of interest to make overlay images of LM and EM data. Using this approach, we were able to make accurate 3D-CLEM overlays of liver tissue and correlate the fluorescent signal to the ultrastructural detail provided by the electron microscope. This workflow can be adapted for other dense cellular tissues and thus act as a guide for other three-dimensional correlative studies. LAY DESCRIPTION: As cells and tissues exist in three dimensions, microscopy techniques have been developed to image samples, in 3D, at the highest possible detail. In light microscopy, fluorescent probes are used to identify specific proteins or structures either in live samples, (providing dynamic information), or in fixed slices of tissue. A disadvantage of fluorescence microscopy is that only the labeled proteins/structures are visible, while their cellular context remains hidden. Electron microscopy is able to image biological samples at high resolution and has the advantage that all structures in the tissue are visible at nanometer (10-9 m) resolution. Disadvantages of this technique are that it is more difficult to label a single structure and that the samples must be imaged under high vacuum, so biological samples need to be fixed and embedded in a plastic resin to stay as close to their natural state as possible inside the microscope. Correlative Light and Electron Microscopy aims to combine the advantages of both light and electron microscopy on the same sample. This results in datasets where fluorescent labels can be combined with the high-resolution contextual information provided by the electron microscope. In this study we present a workflow to guide a tissue sample from the light microscope to the electron microscope and image the ultra-structure of a specific cell type in the liver. In particular we focus on the incorporation of fiducial markers during the sample preparation to help navigate through the tissue in 3D in both microscopes. One sample is followed throughout the workflow to visualize the important steps in the process, showing the final result; a dataset combining fluorescent labels with ultra-structural detail.

RESUMO

INTRODUCCIÓN: La pandemia global de COVID-19 ha provocado una rápida implantación de la telemedicina, pero existe escasa información sobre la satisfacción percibida por el paciente como alternativa a la asistencia presencial. OBJETIVO: Se evalúa la satisfacción del paciente urológico con la teleconsulta durante la pandemia COVID-19. MATERIAL Y MÉTODOS: Estudio observacional, prospectivo transversal, no intervencionista, mediante encuesta telefónica durante el periodo considerado pico de pandemia (marzo-abril 2020). Se realiza una encuesta de calidad compuesta por 11 preguntas sobre la atención urológica durante la pandemia COVID-19 por los facultativos, seleccionando una muestra representativa de los pacientes atendidos en el periodo por teleconsulta. RESULTADOS: Doscientos pacientes fueron contactados telefónicamente para responder a una encuesta de calidad sobre teleconsulta. La distribución de pacientes encuestados entre las consultas monográficas fue homogénea entre el número de consultas citadas en el periodo, requiriendo el 18% de ellos ayuda por familiar. El 60% de los pacientes evitaron acudir a un centro médico durante la pandemia. El 42% de los pacientes encuestados tenían cancelada alguna prueba complementaria, el 59% alguna consulta médica, el 3,5% tratamientos y el 1% intervenciones. El 10% apreciaron un empeoramiento de su sintomatología urológica durante el confinamiento. La resolución subjetiva de la consulta por el facultativo fue alcanzada en el 72% de los casos, siendo la teleconsulta por el urólogo habitual en el 81%. El grado de satisfacción global con la teleconsulta fue de 9 (RIQ 8-10), considerando la teleconsulta como una «opción de asistencia sanitaria» pasada la crisis sanitaria por el 61,5% de los encuestados. CONCLUSIÓN: La teleconsulta ha sido valorada con un alto grado de satisfacción durante la pandemia COVID-19, ofreciendo asistencia continuada a los pacientes urológicos durante la crisis sanitaria. La calidad percibida ofrece un campo de asistencia telemática opcional en pacientes seleccionados, que debe reevaluarse fuera de una situación de confinamiento


INTRODUCTION: The global pandemic of COVID-19 has led to rapid implementation of telemedicine, but there is little information on patient satisfaction of this system as an alternative to face-to-face care. OBJECTIVE: To evaluate urological patient satisfaction with teleconsultation during the COVID-19 pandemic. MATERIAL AND METHODS: Observational, prospective, cross-sectional, non-interventional study carried out by telephone survey during the period considered as the peak of the pandemic (March-April 2020). A quality survey composed of 11 questions on urological care provided by physicians during the COVID-19 pandemic was conducted, selecting a representative sample of patients attended by teleconsultation. RESULTS: Two hundred patients were contacted by telephone to answer a survey on the quality of teleconsultation. The distribution of patients surveyed among the specialized consultations was homogeneous with the number of consultations cited in the period; 18% of them required assistance from family members. Sixty percent of patients avoided going to a medical center during the pandemic. Of the surveyed patients, 42% had cancelled diagnostic tests, 59% had cancelled medical consultations, 3.5% had cancelled treatments and 1% had cancelled interventions. Ten percent reported a worsening of urological symptoms during confinement. According to physicians, consultations were effectively delivered in 72% of cases, with teleconsultation being carried out by their usual urologist in 81%. Teleconsultation overall satisfaction level was 9 (IQI8-10), and 61.5% of respondents consider teleconsultation as a «health care option» after the healthcare crisis. CONCLUSION: Teleconsultation has been evaluated with a high level of satisfaction during the COVID-19 pandemic, offering continuous care to urological patients during the healthcare crisis. The perceived quality offers a field of optional telematic assistance in selected patients, which should be re-evaluated in a period without confinement measures

RESUMO

Emotions not only arise in reaction to an event but also while anticipating it, making this context a means of accessing the emotional value of events. Before now, anticipatory studies have rarely considered whether vocalisations carry information about emotional states. We studied both the grunts of piglets and their spatial behaviour as they anticipated two (pseudo)social events known to elicit positive emotions of different intensity: arrival of familiar conspecifics and arrival of a familiar human. Piglets spatially anticipated both pseudo-social contexts, and the spectro temporal features of grunts differed according to the emotional context. Piglets produced low-frequency grunts at a higher rate when anticipating conspecifics compared to anticipating a human. Spectral noise increased when piglets expected conspecifics, whereas the duration and frequency range increased when expecting a human. When the arrival of conspecifics was delayed, the grunt duration increased, whereas when the arrival of the human was delayed, the spectral parameters were comparable to those during isolation. This shows that vocal expressions in piglets during anticipation are specific to the expected reward. Vocal expressions-both their temporal and spectral features- are thus a good way to explore the emotional state of piglets during the anticipation of challenging events.

RESUMO

Patients with moderate to severe acute respiratory distress syndrome (ARDS) benefit from prone positioning. Although the accuracy of esophageal pressure (Pes) to estimate regional pleural pressure (Ppl) has previously been assessed in the supine position, such data are not available in the prone position in ARDS. In six anesthetized, paralyzed, and mechanically ventilated female pigs, we measured Pes and Ppl into dorsal and ventral parts of the right pleural cavity. Airway pressure (Paw) and flow were measured at the airway opening. Severe ARDS [arterial partial pressure of oxygen ([Formula: see text])/fraction of inspired oxygen ([Formula: see text]) < 100 mmHg at positive end-expiratory pressure (PEEP) of 5 cmH2O] was induced by surfactant depletion. In supine and prone positions assigned in a random order, PEEP was set to 20, 15, 10, and 5 cmH2O and static end-expiratory chest wall pressures were measured from Pes (PEEPtot,es) and dorsal (PEEPtot,PplD) and ventral (PEEPtot,PplV) Ppl. The magnitude of the difference between PEEPtot,es and PEEPtot,PplD was similar in each position [-3.6 cmH2O in supine vs. -3.8 cmH2O in prone at PEEP 20 cmH2O (PEEP 20)]. The difference between PEEPtot,es and PEEPtot,PplV became narrower in the prone position (-8.3 cmH2O supine vs. -3.0 cmH2O prone at PEEP 20). PEEPtot,PplV was overestimated by Pes in the prone position at higher pressures. The median (1st-3rd quartiles) dorsal-to-ventral Ppl gradient was 4.4 (2.4-6.8) cmH2O in the supine position and -1.5 (-3.5 to +1.1) cmH2O in the prone position (P < 0.0001) and marginally influenced by PEEP (P = 0.058). Prone position narrowed end-expiratory dorsal-to-ventral Ppl vertical gradient, likely because of a more even distribution of mechanical forces over the chest wall.NEW & NOTEWORTHY In a porcine model of acute respiratory distress syndrome, we found that static end-expiratory esophageal pressure did not change significantly in prone position compared with supine position at any positive end-expiratory pressure (PEEP) tested between 5 and 20 cmH2O. Prone position was associated with an increased ventral pleural pressure and reduced end-expiratory dorsal-to-ventral pleural pressure (Ppl) vertical gradient, likely due to a more even distribution of mechanical forces over the chest wall.

RESUMO

OBJECTIVE: To assess the short-term incidence of serious complications of surgery for urinary incontinence or pelvic organ prolapse. DESIGN: Prospective longitudinal cohort study using a surgical registry. SETTING: Thirteen public hospitals in France. POPULATION: A cohort of 1873 women undergoing surgery between February 2017 and August 2018. METHODS: Preliminary analysis of serious complications after a mean follow-up of 7 months (0-18 months), according to type of surgery. Surgeons reported procedures and complications, which were verified by the hospitals' information systems. MAIN OUTCOME MEASURES: Serious complication requiring discontinuation of the procedure or subsequent surgical intervention, life-threatening complication requiring resuscitation, or death. RESULTS: Fifty-two women (2.8%, 95% CI 2.1-3.6%) experienced a serious complication either during surgery, requiring the discontinuation of the procedure, or during the first months of follow-up, necessitating a subsequent reoperation. One woman also required resuscitation; no women died. Of 811 midurethral slings (MUSs), 11 were removed in part or totally (1.4%, 0.7-2.3%), as were two of 391 transvaginal meshes (0.5%, 0.1-1.6%), and four of 611 laparoscopically placed mesh implants (0.7%, 0.2-1.5%). The incidence of serious complications 6 months after the surgical procedure was estimated to be around 3.5% (2.0-5.0%) after MUS alone, 7.0% (2.8-11.3%) after MUS with prolapse surgery, 1.7% (0.0-3.8%) after vaginal native tissue repair, 2.8% (0.9-4.6%) after transvaginal mesh, and 1.0% (0.1-1.9%) after laparoscopy with mesh. CONCLUSIONS: Early serious complications are relatively rare. Monitoring must be continued and expanded to assess the long-term risk associated with mesh use and to identify its risk factors.

RESUMO

Bilharzia is the world's second parasitic endemic and its genito-urinary lesions are well described. Ectopic pregnancies on tubal obstruction by bilharzia eggs are reported in African populations. Through a case of clinical observation we report an exceptional case of tubal erythema tubal bilharziasis in a French woman of origin but particularly affectionate by the African woman Africa south of the sahara. where she carries out humanitarian activities in countries in conflits (Democratic Republic Of Congo, Ivory Coast, and Mali).

RESUMO

BACKGROUND: Normocalcaemic primary hyperparathyroidism (NcPHPT) is a new clinical entity being diagnosed increasingly among patients with mild primary hyperparathyroidism (PHPT). The aim of this study was to evaluate quality of life and non-specific symptoms before and after parathyroidectomy in patients with NcPHPT compared with those with hypercalcaemic mild PHPT (Hc-m-PHPT). METHODS: This was a prospective multicentre study of patients with mild PHPT from four university hospitals. Patients were evaluated before operation, and 3, 6 and 12 months after surgery for quality of life using the SF-36-v2® questionnaire, as well as for 25 non-specific symptoms. RESULTS: Before operation, the only statistically significant difference between the NcPHPT and Hc-m-PHPT groups was in the mean(s.d.) blood calcium level (2·54 versus 2·73 mmol; P < 0·001). At 1 year after surgery, the blood calcium level had improved significantly in both groups, with no significant difference between them. Quality of life improved significantly in each group compared with its preoperative score, with regard to the physical component summary (P = 0·040 and P = 0·016 respectively), whereas the mental component summary improved significantly in the Hc-m-PHPT group only (P = 0·043). Only two non-specific symptoms improved significantly in the NcPHPT group compared with nine in the Hc-m-PHPT group. CONCLUSION: Parathyroidectomy mildly improves quality of life and some non-specific symptoms in patients with NcPHPT.

RESUMO

INTRODUCTION: While prone positioning (PP) has been shown to improve patient survival in moderate to severe acute respiratory distress syndrome (ARDS) patients, the rate of application of PP in clinical practice still appears low. AIM: This study aimed to determine the prevalence of use of PP in ARDS patients (primary endpoint), the physiological effects of PP, and the reasons for not using it (secondary endpoints). METHODS: The APRONET study was a prospective international 1-day prevalence study performed four times in April, July, and October 2016 and January 2017. On each study day, investigators in each ICU had to screen every patient. For patients with ARDS, use of PP, gas exchange, ventilator settings and plateau pressure (Pplat) were recorded before and at the end of the PP session. Complications of PP and reasons for not using PP were also documented. Values are presented as median (1st-3rd quartiles). RESULTS: Over the study period, 6723 patients were screened in 141 ICUs from 20 countries (77% of the ICUs were European), of whom 735 had ARDS and were analyzed. Overall 101 ARDS patients had at least one session of PP (13.7%), with no differences among the 4 study days. The rate of PP use was 5.9% (11/187), 10.3% (41/399) and 32.9% (49/149) in mild, moderate and severe ARDS, respectively (P = 0.0001). The duration of the first PP session was 18 (16-23) hours. Measured with the patient in the supine position before and at the end of the first PP session, PaO2/FIO2 increased from 101 (76-136) to 171 (118-220) mmHg (P = 0.0001) driving pressure decreased from 14 [11-17] to 13 [10-16] cmH2O (P = 0.001), and Pplat decreased from 26 [23-29] to 25 [23-28] cmH2O (P = 0.04). The most prevalent reason for not using PP (64.3%) was that hypoxemia was not considered sufficiently severe. Complications were reported in 12 patients (11.9%) in whom PP was used (pressure sores in five, hypoxemia in two, endotracheal tube-related in two ocular in two, and a transient increase in intracranial pressure in one). CONCLUSIONS: In conclusion, this prospective international prevalence study found that PP was used in 32.9% of patients with severe ARDS, and was associated with low complication rates, significant increase in oxygenation and a significant decrease in driving pressure.

RESUMO

Objectives: Antifungal resistance is a significant and emerging threat. Stewardship programmes (SPs) have been proposed as an opportunity to optimize antifungal use. While examples of antifungal SP implementation have been recently described, there is yet to be an overview of interventions and their impacts on performance measures. Methods: We systematically reviewed published articles using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses check-list 2009. MEDLINE was searched using the term 'antifungal stewardship' on 15 February 2017. Eligible studies were those that described an antifungal SP and included an intervention and an evaluation of performance measures. Results: A total of 97 studies were identified and 14 were included. Only five studies reported an antifungal stewardship team composed of all the recommended members. The main intervention was the formulation of recommendations to change treatment (12 of 14). The main performance measure collected was antifungal consumption (10 of 14), followed by antifungal expenditure (7 of 14), adherence to therapeutic advice (4 of 14) and impact on mortality (4 of 14). Antifungal consumption was reduced by 11.8% to 71% and antifungal expenditure by as much as 50%. Adherence to therapeutic advice ranged from 40% to 88%, whereas antifungal SPs had no impact on mortality. Conclusions: All antifungal SPs had an impact, in particular on antifungal consumption and antifungal expenditure. Active intervention including a review of prescriptions seems to have more impact than implementation of treatment guidelines only. According to available published studies, antifungal consumption appears to be the most achievable performance measure to evaluate the impact of an antifungal SP.

RESUMO

INTRODUCTION: MicroRNAs (miRNAs) are small noncoding RNA molecules that exert post-transcriptional effects on gene expression by binding with cis-regulatory regions in target messenger RNA (mRNA). Polymorphisms in genes encoding miRNAs or in miRNA-mRNA binding sites confer deleterious epigenetic effects on cancer risk. miR-146a has a role in inflammation and may have a role as a tumour suppressor. The polymorphism rs2910164 in the MIR146A gene encoding pre-miR-146a has been implicated in several inflammatory pathologies, including cancers of the breast and thyroid, although evidence for the associations has been conflicting in different populations. We aimed to further investigate the association of this variant with these two cancers in an Irish cohort. METHODS: The study group comprised patients with breast cancer (BC), patients with differentiated thyroid cancer (DTC) and unaffected controls. Germline DNA was extracted from blood or from saliva collected using the DNA Genotek Oragene 575 collection kit, using crystallisation precipitation, and genotyped using TaqMan-based PCR. Data were analysed using SPSS, v22. RESULTS: The total study group included 1516 participants. This comprised 1386 Irish participants; 724 unaffected individuals (controls), 523 patients with breast cancer (BC), 136 patients with differentiated thyroid cancer (DTC) and three patients with dual primary breast and thyroid cancer. An additional cohort of 130 patients with DTC from the South of France was also genotyped for the variant. The variant was detected with a minor allele frequency (MAF) of 0.19 in controls, 0.22 in BC and 0.27 and 0.26 in DTC cases from Ireland and France, respectively. The variant was not significantly associated with BC (per allele odds ratio = 1.20 (0.98-1.46), P = 0.07), but was associated with DTC in Irish patients (per allele OR = 1.59 (1.18-2.14), P = 0.002). CONCLUSION: The rs2910164 variant in MIR146A is significantly associated with DTC, but is not significantly associated with BC in this cohort.
