ObjectivesTo assess differences in blood flow momentum (BFM) and kinetic energy (KE) dissipation in a model of cardiac dyssynchrony induced by electrical right ventricular apical (RVA) stimulation compared with spontaneous sinus rhythm.MethodsWe cross-sectionally enrolled 12 consecutive patients (mean age 74±8 years, 60% male, mean left ventricular ejection fraction 58%±6 %), within 48 hours from pacemaker (PMK) implantation. Inclusion criteria were: age>18 years, no PMK-dependency, sinus rhythm with a spontaneous narrow QRS at the ECG, preserved ejection fraction (>50%) and a low percentage of PMK-stimulation (<20%). All the participants underwent a complete echocardiographic evaluation, including left ventricular strain analysis and particle image velocimetry.ResultsCompared with sinus rhythm, BFM shifted from 27±3.3 to 34±7.6° (p=0.016), while RVA-pacing was characterised by a 35% of increment in KE dissipation, during diastole (p=0.043) and 32% during systole (p=0.016). In the same conditions, left ventricle global longitudinal strain (LV GLS) significantly decreased from 17±3.3 to 11%±2.8% (p=0.004) during RVA-stimulation. At the multivariable analysis, BFM and diastolic KE dissipation were significantly associated with LV GLS deterioration (Beta Coeff.=0.54, 95% CI 0.07 to 1.00, p=0.034 and Beta Coeff.=0.29, 95% CI 0.02 to 0.57, p=0.049, respectively).ConclusionsIn RVA-stimulation, BFM impairment and KE dissipation were found to be significantly associated with LV GLS deterioration, when controlling for potential confounders. Such changes may favour the onset of cardiac remodelling and sustain heart failure.

Patients with acute pulmonary embolism (PE) have a wide spectrum of clinical presentations, from incidental findings to sudden cardiac death. Management and treatment recommendations in currently available guidelines vary according to patient risk and haemodynamic profile. A clot-in-transit (CiT) in the right heart chambers may be occasionally identified and is, therefore, an under-recognised but challenging condition, often preceding an abrupt clinical deterioration, and associated with increased mortality. Data on the detection of a CiT are sparse but consistent in attributing negative prognostic relevance, and therefore the presence of CiT should be systematically investigated and recorded in the setting of PE.In this review, the challenges related to the identification of a CiT are highlighted. Here, we propose an algorithm where the role of the Pulmonary Embolism Response Team (PERT) is reinforced. The PERT should convene once the CiT is suspected, to define the timeline for the diagnostic steps and subsequent management on a case-by-case basis. A patient with PE and CiT requires close bedside monitoring and rapid escalation therapy in case of clinical deterioration. Beyond anticoagulation alone, more aggressive strategies can be considered, including systemic thrombolysis, surgical pulmonary embolectomy and the currently emerging catheter-directed therapies.

The angiographic evidence of normal coronary arteries or moderate coronary artery disease is a relatively common finding in patients with a history of angina, with a higher prevalence in females. This condition is not a single pathological entity, but comprises several different presentations, such as cardiac syndrome X, vasospastic angina, myocardial bridges, as well as coronary alterations with more doubtful clinical implications, such as serial moderate coronary artery lesions or focal coronary dilations. These pathological conditions are different in pathophysiology, management, and prognosis, and for this reason their correct diagnostic definition, beyond the angiographic evidence of normal coronary arteries, appears mandatory. This review aims at providing an update in the conundrum of entities comprising angina with normal coronary arteries, and at explaining different diagnostic and therapeutic approaches.

Il riscontro angiografico di coronarie esenti da lesioni stenosanti o affette da lesioni aterosclerotiche definite non emodinamicamente significative caratterizza una discreta percentuale di pazienti con storia di angina, con prevalenza maggiore nel sesso femminile. A definire tale quadro clinico e strumentale concorrono differenti entità nosologiche, come la sindrome X cardiaca, che pare avere un ruolo patogenetico centrale in alterazioni del distretto microvascolare, l’angina legata a vasospasmo coronarico, la presenza di ponte miocardico, e quadri più sfumati, come la presenza di lesioni aterosclerotiche realizzanti stenosi moderate disposte in serie e le ectasie coronariche. Tali quadri patologici presentano differenze fisiopatologiche e cliniche che giustificano atteggiamenti terapeutici e risvolti prognostici molto diversi tra loro. Un corretto inquadramento diagnostico, che superi la sola documentazione coronarografica di “coronarie normali”, appare fondamentale. In questa rassegna passeremo in esame somiglianze e differenze tra i diversi quadri che convergono nell’ampia definizione di angina con coronarie normali.

The aim of this study was to assess the impact of osteopathic manipulative treatment (OMT) on newborn babies admitted at a neonatal intensive care unit (NICU). This was an observational, longitudinal, retrospective study. All consecutive admitted babies were analyzed by treatment (OMT vs. usual care). Treatment group was randomly assigned. Between-group differences in weekly weight change and length of stay (LOS) were evaluated in the overall and preterm populations. Among 1249 babies (48.9% preterm) recorded, 652 received usual care and 597 received OMT. Weight increase was more marked in the OMT group than in the control group (weekly change: +83 g vs. +35 g; p < 0.001). Similar trends were found in the subgroup of preterm babies. A shorter LOS was found in the OMT group vs. the usual care group both in overall population (average mean difference: −7.9 days, p = 0.15) and in preterm babies (−12.3 days; p = 0.04). In severe preterm babies, mean LOS was more than halved as compared to the control group. OMT was associated with a more marked weekly weight increase and, especially in preterm babies, to a relevant LOS reduction: OMT may represent an efficient support to usual care in newborn babies admitted at a NICU.

Over the years, several authors have discussed the possibility of considering somatic dysfunction (SD) as a “nosological element” detectable on palpation. There are many aspects to consider regarding the etiology and diagnosis of SD, and the literature on osteopathic issues provides details on physiological signs that characterize it, including tissue texture changes. Recent knowledge suggests that how tissue and, in particular, connective tissue, responds to osteopathic treatment may depend on the modulation of the inflammation degree. Low-grade inflammation (LGI) may act on the extracellular matrix (ECM) and on cellular elements; and these mechanisms may be mediated by biological water. With its molecules organized in structures called exclusion zones (EZ), water could explain the functioning of both healthy and injured tissues, and how they can respond to osteopathic treatment with possible EZ normalization as a result. The relationship between inflammation and DS and the mechanisms involved are described by several authors; however, this review suggests a new model relating to the characteristics of DS and to its clinical implications by linking to LGI. Tissue alterations detectable by osteopathic palpation would be mediated by body fluids and in particular by biological water which has well-defined biophysical characteristics. Research in this area is certainly still to be explored, but our suggestion seems plausible to explain many dynamics related to osteopathic treatment. We believe that this could open up a fascinating scenario of therapeutic possibilities and knowledge in the future.

Background Recent evidence proved the necessity to improve health care and pain management in newborns. Osteopathic manipulative treatment (OMT) has been largely used to treat painful syndromes as well as term and preterm newborns. Recent studies have demonstrated positive results of osteopathy in reducing length of stay and costs. However, no trials were carried out on pain in newborns. The aim of the present clinical trial is to explore the effectiveness of osteopathic treatment in reducing pain in a sample of preterms. Methods/design A three-armed single blinded placebo-control randomised controlled trial protocol has been designed to primarily evaluate the extent to which OMT is effective in reducing pain in preterms. One hundred and twenty newborns will be enrolled from one tertiary neonatal intensive care unit in central Italy and randomised in three groups: study, sham and control. The study group will be further prospectively randomised in two subgroups: experienced osteopaths and students. All preterms will receive standard medical care. Osteopathic treatment will be applied to the study group only whilst ‘soft touch’ will be administer to the sham group only. Newborns will undergo manual sessions once a week for the entire period of hospitalisation. Blinding will be assured for neonatal staff and outcome assessor. Primary outcome will be the mean difference in baseline score changes of PIPP questionnaire between discharge and entry among the three groups. Secondary outcomes will be: mean difference in length of stay and costs between groups. Statistical analyses will use per-protocol analysis method. Missing data will be handled using last observation carried forward imputation technique. Discussion The present single blinded randomised controlled trial has been designed to explore potential advantages of OMT in the management of newborns’ pain. Currently, based on a patient-centred need-based approach, this research will be looking at the benefit of osteopathic care rather than the efficacy of a specific technique or a pre-determined protocol. Trial registration The protocol has been registered on ClinicalTrials.gov ( NCT02146677 ) on 20 May 2014.

Burnout syndrome (BOS) associated with stress has been documented in health care professionals in many specialties. The emergency department and the pre-hospital healthcare services are highly stressful environments. Little is known about the BOS in critical care nursing staff. The objective of the study is to compare the incidence of BOS and its three domains, namely, emotional exhaustion, depersonalization and reduced professional accomplishment, in two cohorts of critical care nurses: a pre-hospital and a hospital emergency service. A survey using a questionnaire (the Maslach Burnout Inventory-General Survey, MBI-GS), among nurses of two Italian emergency services has been performed: a hospital emergency service (HES, Emergency Department or \"Pronto Soccorso\") and a pre-hospital emergency service (PHES, territorial healthcare service or \"Centrale Operativa 118\"). All 60 nurses surveyed (82% female) filled the questionnaires. BOS-related symptoms have been identified in at least 50% of the nurses in the HES: 50% suffered a medium-high emotional exhaustion, 75% had a medium-high depersonalization and 92.5% had a medium-high reduced professional accomplishment. Among the PEHS nurses, BOS-related symptoms have been identified in at least 60% of the respondents: 60% had a medium-high emotional exhaustion, 70% had a medium-high depersonalization and 95% had a medium-high reduced professional accomplishment. Moreover, the likelihood that a nurse has a severe BOS, that is at least one degree of high burnout or ≥2 degrees of medium burnout, is significantly higher in the group of the PHES than in the HES (90% vs 60%, p <0.02). At least two-thirds of critical care nursing staff had a severe BOS. The incidence of BOS appeared to be similar among PHES and HES nurses with a higher trend for the former. Further interventional studies are needed to investigate the determinants of BOS among critical care nurses and the potentially preventive strategies.

Introduction. Burnout syndrome (BOS) associated with stress has been documented in health care professionals in many specialties. The emergency department and the pre-hospital healthcare services are highly stressful environments. Little is known about the BOS in critical care nursing staff.

Results. All 60 nurses surveyed (82% female) filled the questionnaires. BOS-related symptoms have been identified in at least 50% of the nurses in the HES: 50% suffered a medium-high emotional exhaustion, 75% had a medium-high depersonalization and 92.5% had a medium–high reduced professional accomplishment. Among the PEHS nurses, BOS-related symptoms have been identified in at least 60% of the respondents: 60% had a medium-high emotional exhaustion, 70% had a medium-high depersonalization and 95% had a medium-high reduced professional accomplishment.

Conclusion. At least two-thirds of critical care nursing staff had a severe BOS. The incidence of BOS appeared to be similar among PHES and HES nurses with a higher trend for the former. Further interventional studies are needed to investigate the determinants of BOS among critical care nurses and the potentially preventive strategies.
