INTRODUCTION: Computed tomography pulmonary angiography (CTPA) has not only become the method of choice for diagnosing acute pulmonary embolism (PE), it also allows for risk stratification of patients with PE. To date, no study has specifically examined the predictive value of CTPA findings to assess short-term prognosis in elderly patients with acute PE who are particularly vulnerable to adverse outcomes. METHODS: We studied 291 patients aged ≥65 years with acute symptomatic PE in a prospective multicenter cohort...

It is well known that a strong metabolic interrelationship exists between ureagenesis and gluconeogenesis. In this paper, we present a detailed, overall equation, describing a possible metabolic link between ureagenesis and gluconeogenesis. We adopted a guided approach in which we strongly suggest that students, when faced with the problem of obtaining the overall equation of a metabolic pathway, carefully account for all atoms and charges of the single reactions, as well as the cellular localizations of the substrates, and the related transport systems...

Despite clear potential benefits of outpatient care, most patients suffering from pulmonary embolism (PE) are currently hospitalized due to the fear of possible adverse events. Nevertheless, some teams have increased or envisage to increase outpatient treatment or early discharge. We performed a narrative systematic review of studies published on this topic. We identified three meta-analyses and 23 studies, which involved 3671 patients managed at home (n=3036) or discharged early (n=535). Two main different approaches were applied to select patients eligible for outpatient in recent prospective studies, one based on a list of pragmatic criteria as the HESTIA rule, the other adding severity criteria (i...

We sequenced the genomes of ten Salmonella enterica serovar Infantis containing blaCTX-M-65 isolated from chicken, cattle, and human sources collected between 2012 and 2015 in the United States through routine NARMS surveillance and product sampling programs. We also completely assembled the plasmids from four of the isolates. All isolates had a D87Y mutation in the gyrA gene and harbored between 7 and 10 resistance genes (aph (4)-Ia, aac (3)-IVa, aph(3' )-Ic, blaCTX-M-65, fosA3, floR, dfrA14, sul1, tetA, aadA1) located in two distinct sites of a megaplasmid (∼316-323kb) similar to that described in a blaCTX-M-65-positive S...

OBJECTIVES: Acute massive pulmonary embolism (AMPE) is a life-threatening condition that often induces rapid haemodynamic deterioration. The mortality of surgical embolectomy is still poor in patients with preoperative cardiopulmonary arrest (CPA). We analysed the outcome of surgical pulmonary embolectomy for haemodynamically unstable patients. METHODS: Thirty-one patients underwent surgical embolectomy for haemodynamically unstable AMPE. The indications for surgical embolectomy were (i) <7 days from onset, (ii) haemodynamically unstable, (iii) massive clots in bilateral pulmonary arteries or unilateral pulmonary artery occlusion with a floating clot in the main pulmonary artery or right atrium and (iv) right ventricular dilatation in transthoracic echocardiography...

In mass spectrometry, analytes must be released in the gas phase. There are two representative methods for the gasification of the condensed samples, i.e., ablation and desorption. While ablation is based on the explosion induced by the energy accumulated in the condensed matrix, desorption is a single molecular process taking place on the surface. In this paper, desorption methods for mass spectrometry developed in our laboratory: flash heating/rapid cooling, Leidenfrost phenomenon-assisted thermal desorption (LPTD), solid/solid friction, liquid/solid friction, electrospray droplet impact (EDI) ionization/desorption, and probe electrospray ionization (PESI), will be described...

BACKGROUND: Robotic surgery for rectal resection presents some advantages compared with the traditional technique; however, it also presents some limitations, especially due to the multiple changes of surgical fields. We describe a new technique to perform low-anterior resection using single docking with the rotation of the third arm and our perioperative results. MATERIALS AND METHODS: A total of 31 patients who underwent low-anterior rectal robotic resection with single-docking technique using robotic daVinci SI (Surgical Intuitive System) were included in the study...

We discuss a phenomenon that has received little attention to date in research on dissociative phenomena, namely that self-reports of these phenomena overlap with the tendency to overendorse eccentric items. We review the literature documenting the dissociation-overreporting link and then briefly discuss various interpretations of this link: (1) overreporting is an artifact of measuring dissociative symptoms; (2) dissociative psychopathology engenders overreporting of eccentric symptoms through fantasy proneness or impairments in internal monitoring; (3) an overreporting response style as is evident in malingerers, for example, promotes reports of dissociative symptoms...

Tissue samples from renal cell carcinoma patients were analyzed by electrospray droplet ion beam-induced secondary ion mass spectrometry (EDI/SIMS). Positively- and negatively-charged secondary ions were measured for the cancerous and noncancerous regions of the tissue samples. Although specific cancerous species could not be found in both the positive and negative secondary ion spectra, the spectra of the cancerous and noncancerous tissues presented different trends. For instance, in the m/z range of 500-800 of the positive secondary ion spectra for the cancerous tissues, the intensities for several m/z values were lower than those of the m/z+2 peaks (indicating one double bond loss for the species), whereas, for the noncancerous tissues, the inverse trend was obtained...

Essentials Clinical benefit of hospitalization vs. outpatient treatment in pulmonary embolism (PE) is unknown. We performed a propensity matched cohort study of hemodynamically stable PE patients. Regardless of the risk assessment, hospitalized patients had the highest rate of adverse event. If confirmed, ambulatory care of normotensive PE patients may be preferred whenever possible. SUMMARY: Background The decision to hospitalize or not patients with acute pulmonary embolism (PE) is controversial...

BACKGROUND AND AIM: Chemoradiotherapy (CRT) is the gold standard treatment for anal cancer, which permits the maintenance of the anal function. However, about 30-40% of patients develop local disease progression, for which surgery represents a good salvage therapy. The aim of this study is to evaluate survival and morbidity rate in patients who undergo salvage surgery in our single institution, with an overview of the literature. METHODS: A retrospective study was carried out on patients who underwent surgical treatment of anal canal cancer after failure of CRT...

BACKGROUNDS: Pulmonary embolism (PE) is frequent in subjects with chronic obstructive pulmonary disease (COPD) and associated with high mortality. This multi-center retrospective study was performed to investigate if secondary polycythemia is associated with in-hospital mortality in COPD patients with low-risk PE. METHODS: We identified COPD patients with proven PE between October, 2005 and October, 2015. Patients in risk classes III-V on the basis of the PESI score were excluded...

BACKGROUND: In the event of a postoperative pulmonary embolism (PE), it is generally believed that patients with centrally located emboli will have worse clinical symptoms than those with segmental or subsegmental ones. We studied if a relationship exists between the clinical severity at the time of PE diagnosis and the location of the emboli within the pulmonary vasculature. METHODS: All 269 patients who developed an in-hospital, computed tomography pulmonary angiography-proved, PE following elective total hip arthroplasty or total knee arthroplasty in our institution were studied...

BACKGROUND: Pulmonary embolism (PE) is a common condition managed in the emergency department (ED), with a wide range of morbidity and mortality. Patients are classically admitted for treatment and monitoring of anticoagulation. OBJECTIVE: We sought to evaluate the controversy concerning outpatient therapy for patients with acute PE and investigate the feasibility, safety, and efficacy of outpatient management. DISCUSSION: Patients with venous thromboembolism have historically been admitted for treatment and monitoring for concern of worsening disease or side effects of anticoagulation (bleeding)...

INTRODUCTION: The pulmonary embolism severity index (PESI) or simplified version (sPESI) are widely validated risk scores for the identification of eligible patients for outpatient treatment. Saturation is one of these criteria. For this metric, saturation of 90% or greater is assigned zero points. However, 90% saturation does not always exclude hypoxemic respiratory failure. OBJECTIVE: The aims of this study were first was to define corresponding partial arterial oxygen pressure (PaO2 ) values according to saturation in pulmonary embolism (PE) patients, and the second was to define a target saturation that can exclude hypoxemic respiratory failure and enable secure discharge of PE patients from emergency departments...

OBJECTIVE: The perceptual strain index (PeSI) has been shown to overcome the limitations associated with the assessment of the physiological strain index (PSI), primarily the need to obtain a core body temperature measurement. The PeSI uses the subjective scales of thermal sensation and perceived exertion (RPE) to provide surrogate measures of core temperature and heart rate, respectively. Unfortunately, thermal sensation has shown large variability in providing an estimation of core body temperature...
