In case of failed angioplasty, coronary stenting has gradually emerged as a non-surgical method to restore vessel patency and optimize coronary blood flow. There is still little clinical and angiographic information on the use of radiopaque single loose interdigitating wire stents in angioplasty complicated by threatened or acute closure. Seventy-one patients received Wiktor stents after threatened vessel closure in 53 cases and acute closure in 18 cases. Stent delivery was successful in 98%. In-hospital death occurred in 1 case (1.4%). Stents occlusion were faced in 10 cases (14%), of which 6 presented early and 4 late after the procedure. Urgent bypass surgery was needed in 9 cases (12%) and 7 patients (10%) developed acute myocardial infarction. Serious bleeding complications occurred in 7 cases (10%) and vascular repair was performed in 4 patients (5%). During a follow-up of 20 +/- 10 months, 2 patients died, no myocardial infarction was observed and recurrence of angina was noted in 17 patients (24%). Angiographic analysis showed an acute gain in minimal lumen diameter of 1.71 +/- 0.22 mm and a late loss of 0.63 +/- 0.17 mm. Angiographic restenosis (diameter stenosis > 50%) presented in 20% of patients. Therefore, Wiktor stenting yields similar results than currently used stents in acute closure and strictly defined threatened vessel closure following angioplasty. [less ▲]

Introduction Improving patient flow from emergency department (ED) to in-hospital bed admission has become an everyday challenge. Implementation of an ED bed manager (BM) who monitors hospital beds availability daily has been advocated to reduce boarding time for admitted patient. However, little is known on the actual burden and pitfalls of ED bed coordination. Indeed, overcrowded hospitals often lead to inappropriate transfer from ED to less adapted hospital unit or unit with lower level of care. We design the present study to evaluate the occurrence of such step-down units transfer. Methods This prospective study was conducted in a tertiary care academic hospital accounting for 622 licensed beds and an ED census of 45000/year. In 2014, a BM was implemented as a result of a quality improvement program. Focus was made solely on facilitating and improving patient movements form ED to the hospital wards. The investigators extracted data from a 20-days random observation period in February and March 2015, or a total of 231 patients administered by the BM. Results During this period, mean ED census was 131 (±12) patients /day, of which mean hospital admission rate was 20,6 %. BM administered 12 (±3) of these patients daily. Most of these patients were transferred to an appropriate unit (47.6 %) or a short stay unit (32.1%), while 17.7 % were referred to under adapted units and 2.6 % to step down units. Patients’ average length of stay (LOS) was 32 hours. LOS for patients immediately admitted in the ED short stay unit (n=74) was 26.5 (±22) hours, while it took 35.8 (±26) hours to reach an appropriate unit (n=110) and 35.6 (±27.4) to reach a less-appropriate unit (n=41). Interestingly, patients transferred to a non-appropriate unit (n=6) stayed 29.5 (±15.7) hours in the ED. Communications means used by the BM was face-to-face talk almost half of the cases (n=93) and phone calls for the other half (n=115). Discussion and conclusion These results emphasize the complexity of ED flow coordination. Whether or not such coordination is effective on ED overcrowding or patients’ LOS, this preliminary study identifies the frequent use of short stay and under-adapted units instead of optimal bed location. Besides, further research should clarify the impact of these hospitalisations’ pathways on the quality of care. Finally, these observations indicate the urgent need for early determination of patients who could actually be safely transferred to such units. [less ▲]

After reviewing the basic voltage instability mechanisms, this chapter de-scribes emergency measures that can be used in order to contain voltage insta-bility and prevent a voltage collapse leading to a blackout. A real case of such a voltage collapse in the Hellenic system is presented and analyzed. Emer-gency measures presented include existing or projected controls acting on bulk power delivery transformer load tap changers, as well as direct load shedding. An actual design and application of a load shedding controller in the Hydro-Québec system is presented. [less ▲]

In health care organizations, the need for 24-hour care increases the number of patient’s transfer. Handover and shift changes are now recognized as particularly critical moments for the reliability of care. However, few studies focused specifically on how physicians share relevant information during these moments. Moreover, emergency departments are known to be extremely vulnerable to error, because of high time pressure, frequent interruptions, high variability and number of patients, etc. Our study aimed to estimate how emergency physicians share information about a patient during handover, and to evaluate the impact of a procedure of medical handover standardization. To do this, we conducted a pre-post test on completeness of transmissions. We first performed observations of 50 physicians’ shift changes in an emergency department. All of these were video-recorded and then analyzed. We classified communications into seven categories (identifying information, current pathology, patient’s current status, significant patient’s tests results, priority medical interventions, diagnose and recommendations, and dispositions). After these observations, we elaborated and implemented a standardization procedure, according to literature, analyses of our observations and physicians’ recommendations. We finally assessed this procedure by observing and analyzing 40 handovers, using the same method as previously described. We also evaluated the physician’s opinion about the quality of the transmission with a 7-point Likert scale. Our results showed three significant differences before and after the standardization of communications. Physicians share more information about patient’s tests results, priority interventions and dispositions. Moreover, we found a significant difference of the perceived quality of the standardized handover. [less ▲]

How are identities of alternative forms of organization constructed and how does this process differ relative to normative forms socially expected? In this research we consider identity formation in co-operatives, a population of organizations allied globally through values and practices such as democratic participation, voluntary and open membership, and limited return to capital investment. As an extension of current thinking on identity formation in entrepreneurship and organizational theory, we use co-operatives to explore social expectations and institutional arrangements around form at the societal, population, and organizational levels using a population ecology framework. We develop a research agenda based on propositions that address specific features of identity formation in less typical forms of organization, including tensions with normative business expectations, engagement with identity audiences, embeddedness in networks and alliances, structural factors influencing identity, and identity ambiguity.

Introduction: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the treatment of choice for many patients suffering from hematological malignancies, severe hemoglobinopathies, bone marrow failures or severe primary immunodeficiencies. Graft rejection/failure (GF) is a life-threatening complication following allo-HSCT that is most commonly caused by the reactivity of recipient T cells, natural killer (NK) cells or antibodies against donor grafted hematopoietic cells. The increasing use of allo-HSCT following reduced-intensity conditioning (RIC) and the increasing use of alternative donors (unrelated cord blood and human leukocyte antigen (HLA)-mismatched donor) have resulted in higher frequency of GF. Areas covered: This review describes the pathogenesis and current prevention and treatment of GF as well as agents in development for GF prevention or treatment. Expert opinion: The risk of GF may be reduced in the future by optimizing the conditioning regimens and post-grafting immunosuppression, increasing the number of hematopoietic stem cells (HSCs) and/or immune cells transplanted, optimizing HSC homing and better detecting patients at high risk of GF by searching for pre-transplant donor-specific anti-HLA antibodies in patients given grafts from HLA-mismatched donors, or by closely monitoring donor T- and/or NK-cell chimerism after allo-HSCT following RIC.

Science and Technology Studies (STS) are paying greater attention to the interactions between new technologies and politico-economic orders. Dynamics of promises and expectations with regard to technological developments, and their uptake, play a major role in shaping political-economic policies, institutional practices and wider societal mutations. Informed by the theoretical perspective of co-production (Jasanoff 2004), this paper addresses the political economy of GM soy agriculture in Argentina as both epistemic and social orders. We engage ‘micro’ perspectives looking at situated social experiments with farmers and their interrelations with ‘macro’ phenomena such as capital-labour relations and forms of ‘neoliberalism’. We find that the emerging hybridities in present time’s Argentina are caught between the promissory futures of agroindustrial innovation and the historical, political and material conditions of agricultural production that give rise to these presents in the first place. Looking at three of such hybridities (the blurring of boundaries between modern/national, agriculture/industry and leasing/ownership), we highlight the ways in which elements of political-economic structures and human agency got bound up with technoscientific advances (Jasanoff 2015). Our contribution reveals the importance of the concept of ‘network’ to make sense of the dominant logic of agribusiness and it amounts to ‘rugged’ approach to networks with due attention to the complex topographies of circulating power and morality.
