Background: Needle-free connectors (NFCs) are recommended as closure systems for peripheral and central vascular catheters to reduce needlestick injuries and infections, while potentially reducing blood reflux. However, their performance in short-term dialysis catheters has never been evaluated. The aim of this study was to evaluate the backflow associated with two NFCs (Neutron™ and Tego™) compared to the standard closure., Methods: In this bench study, the physiological blood pressure of the superior vena cava was simulated. Expert operators performed three sealing sequences for each combination of connector and lumens of the catheter, with and without closing the clamp. After that, the backflow was measured in millimeters using a high-precision digital caliper., Results: No combination of caps, lumens, or clamping sequences eliminated the backflow. No differences were observed between standard caps and NFCs in both lumens, apart from the Tego™/ No clamp combination in the proximal lumen that showed higher backflow (standard cap 15 [11; 17] mm vs Tego™ 23 [19; 25] mm, p  < 0.001). Clamping reduced backflow in both the proximal (13 [11; 17] mm vs 20 [13; 25] mm) and distal lumens (12 [11; 16] mm vs 14 [12; 17] mm). No differences were found between standard caps and NFCs in the distal lumen, regardless of clamping. Proximal lumen consistently exhibited larger backflow (14 [12; 22] mm) compared to distal lumens (13 [11; 17] mm, p  = 0.005)., Conclusion: NFCs do not seem to introduce any advantage on backflow reduction as compared to a standard cap combined with lumen and clamping. Our data suggest that clamping should become standard practice when NFCs are used in the management of short-term dialysis catheters., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: In patients complaining common symptoms such as chest/abdominal/back pain or syncope, acute aortic syndromes (AAS) are rare underlying causes. AAS diagnosis requires urgent advanced aortic imaging (AAI), mostly computed tomography angiography. However, patient selection for AAI poses conflicting risks of misdiagnosis and overtesting., Objectives: We assessed the safety and efficiency of a diagnostic protocol integrating clinical data with point-of-care ultrasound (POCUS) and d-dimer (single/age-adjusted cutoff), to select patients for AAI., Methods: This prospective study involved 12 Emergency Departments from 5 countries. POCUS findings were integrated with a guideline-compliant clinical score, to define the integrated pre-test probability (iPTP) of AAS. If iPTP was high, urgent AAI was requested. If iPTP was low and d-dimer was negative, AAS was ruled out. Patients were followed for 30 days, to adjudicate outcomes., Results: Within 1979 enrolled patients, 176 (9 %) had an AAS. POCUS led to net reclassification improvement of 20 % (24 %/-4 % for events/non-events, P < 0.001) over clinical score alone. Median time to AAS diagnosis was 60 min if POCUS was positive vs 118 if negative (P = 0.042). Within 941 patients satisfying rule-out criteria, the 30-day incidence of AAS was 0 % (95 % CI, 0-0.41 %); without POCUS, 2 AAS were potentially missed. Protocol rule-out efficiency was 48 % (95 % CI, 46-50 %) and AAI was averted in 41 % of patients. Using age-adjusted d-dimer, rule-out efficiency was 54 % (difference 6 %, 95 % CI, 4-9 %, vs standard cutoff)., Conclusions: The integrated algorithm allowed rapid triage of high-probability patients, while providing safe and efficient rule-out of AAS. Age-adjusted d-dimer maximized efficiency., Clinical Trial Registration: Clinicaltrials.gov, NCT04430400., (Copyright © 2024 The Authors. Published by Elsevier B.V. All rights reserved.)

Patients with acute stroke often require venous access to facilitate diagnostic investigations or intravenous therapy. The primary aim of this study was to describe the rate and type of complications associated with the placement of a short peripheral catheter (SPC) in patients with acute ischemic or hemorrhagic stroke. A prospective, observational, single-cohort study was conducted at Niguarda Hospital, Italy, with enrolment in the Emergency Department. Adult patients with an ischemic or hemorrhagic stroke requiring an SPC were enrolled. Complications, such as infiltration, occlusion, phlebitis and dislodgment, were recorded daily. Descriptive statistics were used, and the incidence rate ratio (IRR) was estimated to assess the difference in complications, considering catheter calibre, dominant side, exit site, limb, and limb mobility, ictus type (ischemic/haemorrhagic), impairment deficit (language, motor, visual) and EA-DIVA score. A total of 269 participants and 755 SPC were analysed. Removal of SPC due to at least one local complication occurred in 451 (60%). Dislodgment was the major cause of SPC removal (31%), followed by infiltration (18%), occlusion (6%), and phlebitis (5%). The SPC calibre (22G), exit-site other than antecubital and forearm, visual deficit and EA-DIVA ≥ 8 were associated with a higher rate of SPC complications: IRR, 1.71 [1.31; 2.31]; 1.27 [1.01; 1.60], 1.38 [1.06; 1.80], 1.30 [1.04; 1.64], respectively. No other differences in complication rates were observed according to the insertion site, i.e. dominant side, left side, plegic/hyposthenic limb, or exit site. This study provides novel insights into the frequency and types of complications associated with SPC in patients with acute stroke. Compared to the literature, a higher dislodgment rate was observed, being the first cause of SPC removal, whereas no differences in the number of infiltrations, occlusions, and phlebitis were recorded., (© 2024.

Multidrug-resistant organisms (MDROs) are prevalent in patients admitted to the Emergency Department (ED) and increase the risk of inappropriate empirical antibiotic therapy. Risk stratification for MDRO infection is essential to early identify patients requiring empirical broad-spectrum antibiotic therapy, but it remains challenging for emergency physicians. This study aimed to evaluate prevalence, risk factors, and outcomes of patients admitted to the ED with a bloodstream infection (BSI) caused by MDROs. A retrospective observational study enrolling all consecutive adult patients admitted with a BSI to the ED of Niguarda Hospital, Italy, from January 2019 to December 2021 was performed. 757 patients were enrolled, 14.1% with septic shock. 156 (20%) patients had a BSI caused by MDRO: extended-spectrum beta-lactamase (ESBL) producing Enterobacterales were the most prevalent followed by methicillin-resistant Staphylococcus aureus (MRSA). Risk factors for BSI due to MDRO and specifically for ESBL were chronic renal failure (OR 2.2; 95%CI 1.4-3.6), nursing home residency (OR 4.4; 95%CI 1.9-10.2) and antibiotic therapy in the last 90-days (OR 2.6; 95%CI 1.7-4), whereas for MRSA were dialysis (OR 12.3; 95%CI 1.8-83), antibiotic therapy and/or hospital admission in the past 90-days (OR 3.6; 95%CI 1.2-10.6) and ureteral stent or nephrostomy (OR 7.8; 95%CI 1.5-40.9). Patients with BSI due to MDRO had a higher rate of inappropriate empirical antibiotic therapy (50%) and longer length of stay, but no higher in-hospital mortality. Among patients admitted to the ED with a BSI, MDROs are frequent and often associated with inappropriate empirical antibiotic therapy. Specific updated risk factors for MDRO may help clinicians to better identify patients requiring a broader antibiotic therapy in the ED, while awaiting microbiological results., (© 2024.

Background: Few certainties exist regarding optimal management of Blood Pressure (BP) in the very first hours after an ischemic stroke and many questions remain still unanswered. Our work aimed to evaluate the role of BP and its trend as possible determinants of in-hospital mortality (primary outcome), discharge disabilities and hospitalization length (secondary outcomes) in ischemic stroke patients presented with Hypertensive Emergencies (HE)., Methods: We retrospectively evaluated patients presented to Niguarda Hospital, Emergency Department (ED), from 2015 to 2017 with a neurological ischemic HE. BP at ED presentation (T0), its management in ED (T1) and its values at the stroke unit admission (T2) were evaluated., Results: 267 patients were included (0.13 % of all ED accesses and 17.9 % of all ischemic strokes). In the whole population, BP values were not associated with in-hospital mortality while T0 and T2 SBP result were associated to discharge disability and hospitalization length. In pre-specified subgroup analysis these associations were confirmed only in untreated subjects (not anti-hypertensive nor thrombolysis). In fact, no significant relationship can be found between BP values and any secondary outcome in thrombolysis and anti-hypertensive treated patients., Conclusions: BP values and its management can not be related to in-hospital mortality in stroke patients, presented with HE, while they are associated to discharge disability and hospitalization length. In subgroup analysis, results were confirmed only in untreated (not anti-hypertensive therapies nor thrombolytic)., Competing Interests: Declaration of competing interest The authors declare they have no conflict of interest., (Copyright © 2024 European Federation of Internal Medicine.

Catheter-based revascularization procedures were developed as an alternative to systemic thrombolysis for patients with intermediate-high- and high-risk pulmonary embolisms. USAT IH-PE is a retrospective and prospective multicenter registry of such patients treated with ultrasound-facilitated, catheter-directed thrombolysis, whose preliminary results are presented in this study. The primary endpoint was the incidence of pulmonary hypertension (PH) at follow-up. Secondary endpoints were short- and mid-term changes in the echocardiographic parameters of right ventricle (RV) function, in-hospital and all-cause mortality, and procedure-related bleeding events. Between March 2018 and July 2023, 102 patients were included. The majority were at intermediate-high-risk PE (86%), were mostly female (57%), and had a mean age of 63.7 ± 14.5 years, and 28.4% had active cancer. Echocardiographic follow-up was available for 70 patients, and in only one, the diagnosis of PH was confirmed by right heart catheterization, resulting in an incidence of 1.43% (CI 95%, 0.036-7.7). RV echocardiographic parameters improved both at 24 h and at follow-up. In-hospital mortality was 3.9% (CI 95%, 1.08-9.74), while all-cause mortality was 11% (CI 95%, 5.4-19.2). Only 12% had bleeding complications, of whom 4.9% were BARC ≥ 3. Preliminary results from the USAT IH-PE registry showed a low incidence of PH, improvement in RV function, and a safe profile.

The placement of a short peripheral intravenous catheter (sPIVC) is the most common invasive clinical procedure for patients requiring fluid infusion and multiple blood draws. Phlebitis and infiltration represent the most common catheter-related complications. Occlusions, dislocations, and infections are less frequent. Insufficient knowledge and skills may increase the risk of these complications. This review aims to evaluate the effectiveness of training programmes to reduce sPIVC failure amongst hospitalised patients. We will search PubMed, Embase, CINAHL, Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Vascular Specialized Register through the Cochrane Register of Studies, and Google Scholar. We defined the search query using the PICO framework (Participants: health professionals; Intervention: training programme; Comparison: No training programme; Outcomes: all-cause catheter failure). We will include experimental studies evaluating an educational programme to reduce early sPIVC failure amongst hospitalised patients. Two reviewers will independently screen studies for inclusion, extract data, and perform the risk of bias assessment using the Cochrane Effective Practice and Organisation of Care Risk of Bias tool for randomised controlled trials. This review will highlight important perspectives for future studies on the effectiveness of educational programmes focused on reducing the rate of sPIVC complications., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Author(s).)

Background: Acute aortic dissection (AAD) is a rare condition but represents a time-sensitive disease for which a wrong and untimely identification in the triage phase could compromise the subsequent diagnostic, therapeutic path and patient's prognosis. The emergency nurse plays a crucial role in identifying and managing patients with possible AAD. The aim of this paper is to describe the emergency department nursing approach to critical patients with suspected hyperacute/acute AAD., Purpose: It is crucial to examine the emergency departments nursing approach to patients with suspected AAD. It is fundamental to have a rapid and standardized approach related to life-saving procedures, practices, and management of critical patients during the triage phase, with the assessment of the most common presentation of clinical signs and symptoms and patient management during each step in the emergency department., Conclusion: Early identification and diagnosis in ED allow prompt treatment that improves prognosis. The emergency nurse plays a crucial role in correctly identifying and managing patients with acute aortic dissection. High clinical suspicion from the triage stages, early diagnosis, monitoring, and initial clinical stabilization in the emergency department plays a key role while awaiting definitive treatment., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

Background: When helmet CPAP is performed using a Venturi system, filters are frequently interposed in the respiratory circuit to reduce noise within the helmet. The effect of the interposition of these filters on delivered fresh gas flow and the resulting F IO 2 is currently unknown., Methods: In a bench study, 2 different Venturi systems (WhisperFlow and Harol) were used to generate 3 different gas flow/F IO 2 combinations (80 L/min-F IO 2 0.6, 100 L/min-F IO 2 0.5, 120 L/min-F IO 2 0.4). Different combinations of filters were applied at the flow generator input line and/or at the helmet inlet port. Two types of filters were used for this purpose: a heat and moisture exchanger filter and an electrostatic filter. The setup without filters was used as baseline. Gas flow and F IO 2 were measured for each setup., Results: Compared to baseline, the interposition of filters reduced the gas flow between 1-13% ( P < .001). The application of a filter at the Venturi system or at the helmet generated a comparable flow reduction (-3 ± 2% vs -4 ± 2%, P = .12), whereas a greater flow reduction (-7 ± 4%) was observed when filters were applied at both sites ( P < .001). An increase in F IO 2 up to 5% was observed with filters applied. A strong inverse linear relationship ( P < .001) was observed between the resulting gas flow and F IO 2 ., Conclusions: The use of filters during helmet CPAP reduced the flow delivered to the helmet and, consequently, modified F IO 2 . If filters are applied, an adequate gas flow should be administered to guarantee a constant CPAP during the entire respiratory cycle and avoid rebreathing. Moreover, it might be important to measure the effective F IO 2 delivered to the patient to guarantee a precise assessment of oxygenation., Competing Interests: The authors have disclosed no conflicts of interest., (Copyright © 2022 by Daedalus Enterprises.)

Purpose: The aim of this study was to evaluate the rate of successful peripheral cannulation between short-axis and long-axis ultrasound guided techniques., Methods: A single-center, two-arm randomized controlled, intention-to-treat, open-label study was conducted at the Emergency Department, between August and November 2020. Patients requiring a peripheral intravenous catheter insertion and identified as having a difficult intravascular access, were enrolled and followed for up to 96 h.The primary endpoint was the correct placement of the peripheral intravenous catheter. The secondary endpoints were number of venipunctures, intra-procedural pain, local complications, and positive blood return during the follow up., Results: A total of 283 patients were enrolled: 141 subjects were randomized to the short-axis and 142 to the long-axis group. Success rate was 96.45% (135/141; 95% CI, 91.92%-98.84%) in the short-axis group compared with 92.25% (132/142; 95% CI, 86.56%-96.07%) in the long-axis group ( p  = 0.126). No significant differences were found in terms of intraprocedural pain and local complications. Higher rate of positive blood return at 72 h [3/17 long-axis, 14/17 short-axis ( p  = 0.005)] and 96 h [1/10 long-axis, 9/10 short-axis 96 h, ( p  = 0.022)] was found for the short-axis group., Conclusions: No differences were found between short-axis and long-axis techniques in terms of success rate, intraprocedural pain, and local complications. Despite this, a slightly higher success rate, a lower number of venipunctures, and a higher rate of positive blood return at 72 and 96 h together with an easier ultrasound technique could suggest a short-axis approach.

The aim of this article is to describe the importance of a multidisciplinary team dedicated to noninvasive ventilation training of the emergency department's staff. In our experience, the presence of a medical and nursing "noninvasive ventilation group" made it possible to quickly teach expertise on the management of noninvasive ventilation of COVID-19 patients among emergency department doctors and nurses. This allowed improving a standardized approach regarding the identification and ventilatory assistance of patients with SARS-CoV-2 pneumonia needing ventilatory support, the correct use of the devices, and quick identification and reduction of the complications associated with noninvasive ventilation. In this article, we would like to encourage the formation of similar working groups in all situations where this is not yet present., (Copyright © 2022 Wolters Kluwer Health, Inc.

LUS patterns of COVID-19 pneumonia have been described and shown to be characteristic. The aim of the study was to predict the prognosis of patients with COVID-19 pneumonia, using a score based on LUS findings., Materials and Methods:  An observational, retrospective study was conducted on patients admitted to Niguarda hospital with a diagnosis of COVID-19 pneumonia during the period of a month, from March 2 nd to April 3 rd 2020. Demographics, clinical, laboratory, and radiological findings were collected. LUS was performed in all patients. The chest was divided into 12 areas. The LUS report was drafted using a score from 0 to 3 with 0 corresponding to A pattern, 1 corresponding to well separated vertical artifacts (B lines), 2 corresponding to white lung and small consolidations, 3 corresponding to wide consolidations. The total score results from the sum of the scores for each area. The primary outcome was endotracheal intubation, no active further management, or death. The secondary outcome was discharge from the emergency room (ER)., Results:  255 patients were enrolled. 93.7 % had a positive LUS. ETI was performed in 43 patients, and 24 received a DNI order. The general mortality rate was 15.7 %. Male sex (OR 3.04, p = 0.014), cardiovascular disease and hypertension (OR 2.75, p = 0.006), P/F (OR 0.99, p < 0.001) and an LUS score > 20 (OR 2.52, p = 0.046) were independent risk factors associated with the primary outcome. Receiver operating characteristic (ROC) curve analysis for an LUS score > 20 was performed with an AUC of 0.837. Independent risk factors associated with the secondary outcome were age (OR 0.96, p = 0.073), BMI (OR 0.87, p = 0,13), P/F (OR 1.03, p < 0.001), and LUS score < 10 (OR 20.9, p = 0.006). ROC curve analysis was performed using an LUS score < 10 with an AUC 0.967., Conclusion:  The extent of lung abnormalities evaluated by LUS score is a predictor of a worse outcome, ETI, or death. Moreover, the LUS score could be an additional tool for the safe discharge of patient from the ER., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Background: During COVID-19 outbreak, with the increasing number of patients presenting with acute respiratory failure, a large use of non invasive positive pressure ventilation was done in the emergency departments and medical wards despite the lack of recommendations., Objectives: This study describes the clinical characteristics of patients presenting to the hospital with acute respiratory failure due to COVID-19 related pneumonia undergoing treatment with helmet continuous positive airway pressure (CPAP) with a strict nursing evaluation and monitoring., Methods: A case series study enrolling adult patients admitted to an emergency department of an Italian hospital with acute respiratory failure due to COVID-19 pneumonia from March 18th to April 18th, 2020, was conducted. Only patients who strictly followed a local CPAP protocol were enrolled., Results: A total of 52 patients were included in this study. Thirty-eight patients (73%) were judged eligible for endotracheal intubation (ETI). Eighteen (34.6%) were intubated. Sixteen (30.8%) patients died: seven (38.9%) and nine (26.5%) in the eligible-for-ETI and non eligible-for-ETI group, respectively. The median hospital length of stay was different in the ETI and non-ETI group: 26 days (interquartile range [IQR]: 16-37) vs 15 days [IQR 9-17] (p = 0.005). The median invasive mechanical ventilation time was 11 days [IQR 7-21] with an ICU length of stay of 14.5 days [IQR 10-28]. During the CPAP trial, among patients eligible for ETI variations over time for positive end-expiratory pressure (p = 0.003) and respiratory rate (p = 0.059) were found between intubated and non-intubated patients., Conclusions: A short closed monitored CPAP trial could be considered for acute respiratory failure due to COVID-19 pneumonia before considering ETI. A progressive positive end-expiratory pressure titration should target reduction in a patient's respiratory rate. More studies are needed to evaluate the efficacy and predictors of failure of CPAP and non-invasive positive pressure ventilation in patients with acute respiratory failure due to COVID-19 pneumonia., (Copyright © 2021 Australian College of Critical Care Nurses Ltd.

An ongoing outbreak of pneumonia associated with severe acute respiratory coronavirus 2 (SARS-CoV-2) occurred at the end of February 2020 in Lombardy, Italy. We analyzed data from a retrospective, single-center case series of 310 consecutive patients, with confirmed SARS-CoV-2 infection, admitted to the emergency room. We aimed to describe the clinical course, treatment and outcome of a cohort of patients with COVID-19 pneumonia, with special attention to oxygen delivery and ventilator support. Throughout the study period, 310 consecutive patients, with confirmed SARS-CoV-2 infection, attended the Emergency Room (ER), of these, 34 were discharged home directly from the ER. Of the remaining 276 patients, the overall mortality was 30.4%: 7 patients died in the ER and 77 during hospitalization. With respect to oxygen delivery: 22 patients did not need any oxygen support (8.0%), 151 patients were treated with oxygen only (54.7%), and 49 (17.8%) were intubated. 90 patients (32.6%) were treated with CPAP (Continuous Positive Airway Pressure) or NIV (Non Invasive Ventilation); in this group, 27 patients had a Do Not Intubate (DNI) order and were treated with CPAP/NIV as an upper threshold therapy, showing high mortality rate (88.9%). Among the 63 patients treated with CPAP/NIV without DNI, NIV failure occurred in 36 patients (57.1%), with mortality rate of 47.2%. Twenty-seven (27) patients were treated with CPAP/NIV without needing mechanical ventilation and 26 were discharged alive (96.3%). The study documents the poor prognosis of patients with severe respiratory failure, although a considerable minority of patients treated with CPAP/NIV had a positive outcome.

Background: During the COVID-19 pandemic, the number of individuals needing hospital admission has sometimes exceeded the availability of hospital beds. Since hospitalization can have detrimental effects on older individuals, preference has been given to younger patients. The aim of this study was to assess the utility of hospitalization for elderly affected by COVID-19. We hypothesized that their mortality decreases when there is greater access to hospitals., Methods: This study examined 1902 COVID-19 patients consecutively admitted to three large hospitals in Milan, Italy. Overall mortality data for Milan from the same period was retrieved. Based on emergency department (ED) data, both peak and off-peak phases were identified. The percentage of elderly patients admitted to EDs during these two phases were compared by calculating the standardized mortality ratio (SMR) of the individuals younger than, versus older than, 80 years., Results: The median age of the patients hospitalized during the peak phase was lower than the median age during the off-peak phase (64 vs. 75 years, respectively; p <0.001). However, while the SMR for the younger patients was lower during the off-peak phase (1.98, 95% CI: 1.72-2.29 versus 1.40, 95% CI: 1.25-1.58, respectively), the SMR was similar between both phases for the elderly patients (2.28, 95% CI: 2.07-2.52 versus 2.48, 95% CI: 2.32-2.65, respectively)., Conclusions: Greater access to hospitals during an off-peak phase did not affect the mortality rate of COVID-19-positive elderly patients in Milan. This finding, if confirmed in other settings, should influence future decisions regarding resource management of health care organizations., Competing Interests: The authors have declared that no competing interests exist.

With the rapid pandemic spread of the novel coronavirus (SARS-CoV2), Emergency Departments of affected countries are facing an increasing number of patients presenting with hypoxemic respiratory failure due to coronavirus disease 2019 (COVID-19). Providing mechanical support and endotracheal intubation can be challenging due to a number of patients larger than usual, often exceeding available resources. Considering the lack of recommendations available, we developed a flowchart to standardize the first approach to patients presenting to the Emergency Department with hypoxemic respiratory failure due to COVID-19.

Background: Although previous studies showed an increasing prevalence of infections due to multi-drug resistant (MDR) bacteria in the community, specific data on sepsis are lacking. We aimed to assess prevalence, risk factors and outcomes of patients with sepsis due to MDR bacteria., Methods: An observational, retrospective study was conducted on consecutive adult patients coming from the community and admitted to the Policlinico Hospital, Milan, Italy, with a diagnosis of sepsis between January 2011 and December 2015. Primary study outcome was in-hospital mortality., Results: Among 518 patients, at least one MDR bacteria was isolated in 88 (17%). ESBL+ Enterobacteriaceae were the most prevalent MDR bacteria (9.7%) followed by MRSA (3.9%). Independent risk factors for sepsis due to MDR bacteria were septic shock (OR: 2.2; p  = 0.002) and hospitalization in the previous 90 days (OR: 2.3; p  = 0.003). Independent risk factors for sepsis due to ESBL+ bacteria were hospitalization in the previous 90 days (OR: 2.1; p  = 0.02) and stroke (OR: 2.1; p  = 0.04). A significantly higher mortality was detected among patients with vs. without MDR bacteria (40.2% vs. 23.1% respectively, p  = 0.001). Independent risk factors for mortality among patients with sepsis were coagulation dysfunction (OR: 3.2; p  = 0.03), septic shock (OR: 3.2; p  = 0.003), and isolation of a MDR bacteria (OR: 4.6; p  < 0.001)., Conclusion: In light of the prevalence and impact of MDR bacteria causing sepsis in patients coming from the community, physicians should consider ESBL coverage when starting an empiric antibiotic therapy in patients with specific risk factors, especially in the presence of septic shock., Competing Interests: Competing interestsThe authors declare that they have no competing interests.

Hypertensive urgencies-emergencies are important and common events. They are defined as a severe elevation in BP, higher than 180/120 mmHg, associated or not with the evidence of new or worsening organ damage for emergencies and urgencies respectively. Anamnestic information, physical examination and instrumental evaluation determine the following management that could need oral (for urgencies) or intravenous (for emergencies) anti-hypertensives drugs. The choice of the specific drugs depend on the underlying causes of the crisis, patient's demographics, cardiovascular risk and comorbidities. For emergencies a maximum BP reduction of 20-25% within the first hour and then to 160/110-100 over next 2-6 h, is considered appropriate with a further gradual decrease over the next 24-48 h to reach normal BP levels. In the case of hypertensive urgencies, a gradual lowering of BP over 24-48 h with an oral medication is the best approach and an aggressive BP lowering should be avoided. Subsequent management with particular attention on chronic BP values control is important as the right treatment of the acute phase.
