The Impact

Combat trauma wounds with invasive fungal infections (IFIs) are often polymicrobial with fungal and bacterial growth, but the impact of the wound microbiology on clinical outcomes is uncertain. Our objectives were to compare the microbiological features between IFI and non-IFI wounds and evaluate whether clinical outcomes differed among IFI wounds based upon mold type. Data from U.S. military personnel injured in Afghanistan with IFI wounds were examined. Controls were matched by the pattern/severity of injury, including blood transfusion requirements. Wound closure timing was compared between IFI and non-IFI control wounds (with/without bacterial infections). IFI wound closure was also assessed according to mold species isolation. Eighty-two IFI wounds and 136 non-IFI wounds (63 with skin and soft tissue infections [SSTIs] and 73 without) were examined. The time to wound closure was longer for the IFI wounds (median, 16 days) than for the non-IFI controls with/without SSTIs (medians, 12 and 9 days, respectively;P< 0.001). The growth of multidrug-resistant Gram-negative rods was reported among 35% and 41% of the IFI and non-IFI wounds with SSTIs, respectively. Among the IFI wounds, times to wound closure were significantly longer for wounds withMucoralesgrowth than for wounds with non-Mucoralesgrowth (median, 17 days versus 13 days;P< 0.01). When wounds withMucoralesandAspergillusspp. growth were compared, there was no significant difference in wound closure timing. Trauma wounds with SSTIs were often polymicrobial, yet the presence of invasive molds (predominant types: orderMucorales,Aspergillusspp., andFusariumspp.) significantly prolonged the time to wound closure. Overall, the times to wound closure were longest for the IFI wounds withMucoralesgrowth.

The Impact

Abstract MDS comprises a spectrum of clonal hematopoietic disorders with very heterogeneous clinical courses. Several classification and scoring systems have been developed in an attempt to define subgroups of patients with similar prognoses. The International Prognostic Scoring System (IPSS) incorporates marrow myeloblast count, karyotype, and peripheral blood cytopenias. The recent addition of transfusion requirements to the IPSS (WPSS) has sharpened this prognostic tool. Isolated neutropenia is not reflected in these classifications, but bacterial and fungal colonization and infection are problems in patients with MDS. Hematopoietic cell transplantation is the only treatment strategy that has been shown to have curative potential, and many patients come to transplantation with neutropenia, particularly when the disease progresses. We wanted to determine the impact of neutropenia before transplantation on transplant success. We reviewed results in 291 patients with MDS (including MDS that had transformed to AML [tAML]), 1 to 66 (median 50) years of age, who from 1994 through 2003 were transplanted from related or unrelated donors following conditioning with myeloablative regimens. There were 178 patients (61%) who had neutropenia, defined as &lt;1,500/microliter; in 16 of these (9%) neutropenia was an isolated finding. Among the 178 patients, 137 (47%) had neutrophil counts below 1,000, and 86 (30%) below 500. Patients with neutropenia following recent chemotherapy were excluded. The risk of clinically relevant bacterial infections after transplantation was significantly increased in patients with neutropenia (p=0.001). Neutropenic patients had an increased risk for infections with gram-positive (relative risk [RR] 1.77, p=0.02), but not gram negative bacteria (RR 1.33, p=0.53). Specific organisms for which the RR was significantly increased included coagulase negative Staphylococcus, Bacillus species and Corynebacterium spp., suggesting that at least part of this risk was associated with intravascular catheters. The RR for invasive fungal infections (Candida and Aspergillus spp.) was 2.56 (p=0.03) for patients with &lt;1,500 neutrophils. The hazard rate (HR) for non-relapse mortality by day 100 (21%) was 1.8 (p=0.03), and by 5 years (42%) was 1.62 (p=0.01). The most frequent causes of death were infections. The HR for 5-year mortality was 1.55 (p=0.007) for neutropenic patients. The pattern for the small group of patients with isolated neutropenia was identical to that for all patients with neutropenia. Pre-transplant neutropenia had no significant impact on engraftment or graft-versus-host disease. The probability of survival did not differ significantly between patients with IPSS scores of 0 and 0.5 with isolated or multiple cytopenias. In summary, only few patients with MDS who undergo transplantation have isolated neutropenia. However, pre-transplant neutropenia in patients with MDS is associated with a significantly increased risk of posttransplant bacterial infections, fungal infections, and non-relapse mortality, and a decreased probability of survival after myeloablative transplantation. A correlation with pre-transplantation colonization remains to be determined. Intensified and possibly extended antibiotic coverage should be considered.

Abstract Few reports have focused on the impact of ABO incompatibility on the clinical outcomes, after unrelated cord blood transplantation (UCBT). Therefore, we retrospectively analyzed the impact of ABO mismatching on the clinical outcomes of 177 patients with hematologic malignancies, which underwent single UCBT in Anhui Provincial Hospital from May 2008 to April 2014. The study patients included 86 ABO-identical, 52 minor, 32 major, and 11 bidirectional ABO-incompatible recipients. All of them received a homogeneous intensified myeloablative pre-transplantation conditioning regimen of total body irradiation (TBI)cyclophosphamide (CY) [TBI (total,12 Gy; four fractions) and CY (60 mg/kg daily for 2 days)] (age≥14 years) or BuCY2 [busulfan (0.8 mg/kg every 6 h for 4 days) and CY]. Medians of 3.85×107/kg (range, 1.03-10.43) total nucleated cell (TNC) and 2.0×105/kg (range, 0.45-6.88) CD34+cells were transfused. Of the 177 patients who underwent UCBT, 169 achieved successful neutrophil engraftment. In patients receiving ABO-identical, minor, major, and bidirectional ABO-incompatible UCBT, the cumulative incidences of neutrophil engraftment were 92.7%, 100%, 96.9% and 90.9%, respectively (P=0.509). The median days to achieve neutrophil engraftment were 17, 18, 17, and 20, respectively (P=0.409). The cumulative incidences of platelet engraftment were 81.7%, 86.5% , 87.5% and 63.6%, respectively(P=0.436) .And the median days to achieve platelet engraftment for the 4 groups were 36, 40, 36, and 38, respectively; (P=0.545). All of the data did not show any significant difference among the 4 groups. Neutrophil engraftment(cumulative incidence, 95.5% versus 95.3% , P=0.861; median day, 17 versus 18, P=0.717) also did not differ significantly between the ABO-identical/minor ABO-incompatible and major/bidirectional ABO-incompatible recipients (HR1.08, P=0.680). And platelet engraftment (83.6% versus 81.4%, P=0.964; median day, 38 versus 37, P=0.699) reached the similar result (HR1.104, P=0.621). We investigated the results from a 169-patient population with neutrophil engraftment, the average units of platelets (Plts) and red blood cells (RBCs) transfused during the hospitalization after the UCBT were 0.204 units/kg(range, 0.03-1.45)and 0.159 units/kg (range, 0-1.56).In patients with ABO-identical, minor, major, and bidirectional ABO-incompatible UCBT, the average units of Plts transfused after UCBT were 0.221, 0.202, 0.169, and 0.195 units/kg(P=0.53), respectively, and the average units of RBCs transfused were 0.151, 0.156, 0.163, and 0.221 units/kg (P=0.847), respectively. No significant differences in the transfusion requirements among the 4 groups were noted, so did the comparison between the ABO-identical/minor ABO-incompatible and major/bidirectional ABO-incompatible recipients. With a median follow-up of 12 months (range, 3-74 months), the disease-free survival (DFS) rates among the ABO-identical, minor, major, and bidirectional ABO-incompatible groups were 67.1%, 57.7%, 62.5 % and 54.5%, respectively (P=0.804), and the overall survival (OS) also did not differ significantly among the four groups (68.3%, 61.5%, 65.6%, and 63.6%, respectively; P=0.929). When it came to the comparison between the ABO identical/minor incompatible group and the ABO major/bidirectional incompatible group, the DFS (63.4% versus 60.5%; P=0.995) and OS estimates (65.7% versus 65.1%; P=0.820) were not significantly different, either. What’s more, none of the patients clinical developed severe immune hemolysis or pure red-cell aplasia after transplantation. In summary, the results above indicated that :1) ABO incompatibility did not seem to have a significant impact on clinical outcomes after UCBT, such as engraftment, transfusion requirements and survival. 2) No patients developed pure red-cell aplasia after UCBT. 3) In addition, we also compared the outcomes between the ABO-identical and bidirectional ABO-incompatible groups, even it did not show any significant difference, the former did better on platelet engraftment (81.7% versus 63.6%) and DFS (67.1 versus 54.5%). The reason led to this result may be the lack of bidirectional ABO-incompatible recipients. Therefore, we’d better avoid selecting bidirectional ABO-incompatible in UCBT to improve the patients’ recovery and survival time. Disclosures No relevant conflicts of interest to declare.

ABSTRACTVancomycin has been a key antibiotic agent for the treatment of methicillin-resistantStaphylococcus aureus(MRSA) infections. However, little is known about the relationship between vancomycin MIC values at the higher end of the susceptibility range and clinical outcomes. The aim of this study was to determine the impact of MRSA bacteremia on clinical outcomes in patients with a vancomycin MIC near the upper limit of the susceptible range. Patients with MRSA bacteremia were divided into a high-vancomycin-MIC group (2 μg/ml) and a low-vancomycin-MIC group (≤1.0 μg/ml). We examined the relationship between MIC, genotype, primary source of bacteremia, and mortality. Ninety-four patients with MRSA bacteremia, including 31 with a high vancomycin MIC and 63 with a low MIC were analyzed. There was no significant difference between the presence ofagrdysfunction and SCCmectype between the two groups. A higher vancomycin MIC was not found to be associated with mortality. In contrast, high-risk bloodstream infection sources (hazard ratio [HR], 4.63; 95% confidence interval [CI] = 1.24 to 17.33) and bacterial eradication after treatment (HR, 0.06; 95% CI = 0.02 to 0.17), irrespective of vancomycin MIC, were predictors of all-cause 30-day mortality. Our study suggests that a high-risk source of bacteremia is likely to be associated with unfavorable clinical outcomes, but a high vancomycin MIC in a susceptible range, as well as genotype characteristics, are not associated with mortality.

Abstract Background As opposed to Staphylococcus. aureus bacteremia, there are no guidelines to recommend repeating blood cultures in Gram-negative bacilli bacteremia (GNB). Several studies have questioned the utility of follow-up blood cultures (FUBCs) in GNB, but the impact of this practice on clinical outcomes is not fully understood. Our aim was to study the practice of obtaining FUBCs in GNB at our institution and to assess it’s impact on clinical outcomes. Methods We conducted a retrospective, single-center study of adult patients, ≥ 18 years of age admitted with GNB between January 2017 and December 2018. We aimed to compare clinical outcomes in those with and without FUBCs. Data collected included demographics, comorbidities, presumed source of bacteremia and need for intensive care unit (ICU) admission. Presence of fever, hypotension /shock and white blood cell (WBC) count on the day of FUBC was recorded. The primary objective was to compare 30-day mortality between the two groups. Secondary objectives were to compare differences in 30-day readmission rate, hospital length of stay (LOS) and duration of antibiotic treatment. Mean and standard deviation were used for continuous variables, frequency and proportion were used for categorical variables. P-value &lt; 0.05 was defined as statistically significant. Results 482 patients were included, and of these, 321 (67%) had FUBCs. 96% of FUBCs were negative and 2.8% had persistent bacteremia. There was no significant difference in 30-day mortality between those with and without FUBCs (2.9% and 2.7% respectively), or in 30-day readmission rate (21.4% and 23.4% respectively). In patients with FUBCs compared to those without FUBCs, hospital LOS was longer (7 days vs 5 days, P &lt; 0.001), and mean duration of antibiotic treatment was longer (14 days vs 11 days, P &lt; 0.001). A higher number of patients with FUBCs needed ICU care compared to those without FUBCs (41.4% and 25.5% respectively, P &lt; 0.001) Microbiology of index blood culture in those with and without FUBCs Outcomes in those with and without FUBCs FUBCs characteristics Conclusion Obtaining FUBCs in GNB had no impact on 30-day mortality or 30-day readmission rate. It was associated with longer LOS and antibiotic duration. Our findings suggest that FUBCs in GNB are low yield and may not be recommended in all patients. Prospective studies are needed to further examine the utility of this practice in GNB. Disclosures All Authors: No reported disclosures

Purpose: Evaluate the impact of hybrid operating room (HOR) guidance on the long-term clinical outcomes following fenestrated and branched endovascular repair (F-BEVAR) for complex aortic aneurysms. Materials and Methods: Prospectively collected registry data were retrospectively analyzed to compare the procedural, short- and long-term outcomes of consecutive F-BEVAR performed from January 2010 to December 2014 under standard mobile C-arm versus hybrid room guidance in a high-volume aortic center. Results: A total of 262 consecutive patients, including 133 patients treated with a mobile C-arm equipped operating room and 129 with a HOR guidance, were enrolled in this study. Patient radiation exposure and contrast media volume were significantly reduced in the HOR group. Short-term clinical outcomes were improved despite higher case complexity in the HOR group, with no statistical significance. At a median follow-up of 63.3 months (Q1 33.4, Q3 75.9) in the C-arm group, and 44.9 months (Q1 25.1, Q3 53.5, p=0.53) in the HOR group, there was no statistically significant difference in terms of target vessel occlusion and limb occlusion. When the endograft involved 3 or more fenestrations and/or branches (complex F-BEVAR), graft instability (36% vs 25%, p=0.035), reintervention on target vessels (20% vs 11%, p=0.019) and total reintervention rates (24% vs 15%, p=0.032) were significantly reduced in the HOR group. The multivariable Cox regression analysis did not show statistically significant differences for long-term death and aortic-related death between the 2 groups. Conclusion: Our study suggests that better long-term clinical outcomes could be observed when performing complex F-BEVAR in the latest generation HOR.

There may be conflict between the requirements of surgical training and those of the clinical service if training has an impact on clinical outcomes. One area of potential impact is perioperative blood loss. We compared total and 12-hour blood loss after 2,079 consecutive cardiac operations performed over 2 years by trainees and consultants. One- and two-way analyses of variance with EuroSCORE and surgeon status as factors were carried out to evaluate the impact of surgeon status on blood loss. There was no difference in blood loss between consultants and trainees. We also compared the rates between consultants and trainees of patients returning to the operating room due to bleeding. This showed a significant difference, with trainees having a higher rate of investigation for bleeding. Cardiac surgical training can be achieved without an adverse effect on blood loss, but it may be associated with a higher rate of re-intervention for bleeding.

Background/aims Stroke early supported discharge services were introduced to provide a comprehensive stroke specialist therapy input, while reducing cost of acute care. Early supported discharge services resulted in better health-related outcomes. A consensus has not yet been established regarding specific early supported discharge patient characteristics and clinical profile. The main aim of this study was to establish evidence to support the development of an early supported discharge patient profile (demographics and clinical) and eligibility criteria to enable early supported discharge services achieve their purposes of reducing post-stroke disability and institutionalisation rates. This article outlines the relationship between early supported discharge patients' clinical profiles and clinical outcomes, in terms of disability, goal attainment and institutionalisation rates. Methods A retrospective review of data was implemented to determine whether specific early supported discharge patients' clinical profiles and characteristics correlate with clinical outcomes. Data were collected for patients admitted to the Suffolk Stroke Early Supported Discharge Service between August and October 2016, comprising patients' demographics and clinical profiles, including stroke type, Barthel Index and Modified Rankin Scale. Performance data were collected at the end of the early supported discharge service including therapy frequency and intensity, as well as clinical outcomes including the Goal Attainment Scale. Results Data were collected for 53 patients. Data were analysed for all patients in three groups: goals not achieved; goals achieved; and goals achieved to a higher level), according to the Goal Attainment Scale. A Chi-square test showed no significant difference with regard to sex and stroke side (P=0.27). Analysis of variance revealed no significant difference in age. Conversely, results showed a significant association between goal attainment and the stroke subtype, severity and length of hospital stay. Conclusions Specific clinical characteristics and disease profiles correlate with functional outcomes and could influence goal attainment and functional status. A specific patient cohort seems to benefit the most from early supported discharge services in terms of optimised functional outcomes and recovery.

Purpose The authors assumed PSM would be higher in the public sector, but they set up a trial to find out if this was the case. Design/methodology/approach To test their theories, the authors conducted two independent surveys. The first consisted of 220 usable responses from public sector employees in Changsha, China. The second survey involved 260 usable responses from private sector employees taking an MBA course at a university in the Changsha district. A questionnaire was used to assess attitudes. Findings The results found no significant difference between the impact of public sector motivation (PSM) on employee performance across the public and private sectors. The data showed that PSM had a significant impact on self-reported employee performance, but the relationship did not differ much between sectors. Meanwhile, it was in the private sector that PSM had the greatest impact on intention to leave. Originality/value The authors said the research project was one of the first to test if the concept of PSM operated in the same way across sectors. It also contributed, they said, to the ongoing debate about PSM in China.

PurposeWhile operational factors reduce construction workers' productivity in Zimbabwe, the impact of the people-centred management aspects has not been empirically interrogated as a remedy. This article reports on a study that sought to determine significant people-centred management aspects that lead to improved labour productivity and assesses the existence of statistically significant differences due to the demographic variables of respondents. Demographic-specific strategies that enhance construction “workers” productivity were revealed.Design/methodology/approachThe survey research design using a self-administered questionnaire was deployed to collect the primary data. The design followed a positivist paradigm to evaluate objectively how people-centred management affects construction workers' productivity. The statistical data were descriptively and inferentially analysed.FindingsPeople-centred management was determined to be significant in improving construction workers' productivity, with the most significant aspect being the building of employee confidence in related approaches. Designations and educational levels mostly indicated a statistically significant difference in several aspects that included the adoption of a functional reward culture for workers and training on people-centred principles. Training on-site management and construction workers in people-centred management and its application are crucial to improving construction workers' productivity.Research limitations/implicationsConstruction companies should drastically improve their concern for people while they sustain a high concern for production within their construction sites. Although several factors affect construction workers' productivity, this study determined that management-related factors and people-centred management were significant towards influencing low productivity in Zimbabwe.Originality/valueThe study determined people-centred management and demographic-specific interventions as being able to improve construction workers' productivity in Zimbabwe.

Background: Based on 2011 ACCF/AHA/SCAI PCI guideline, it is recommended that PCI should be performed at hospital with onsite cardiac surgery. But, recent data suggests that there is no significant difference in clinical outcomes following primary or elective PCI between hospitals with and without onsite cardiac surgery. The proportion of PCI centers without onsite cardiac surgery comprises approximately more than half of all PCI centers in Japan. We examined the impact of with or without onsite cardiac surgery on clinical outcomes following PCI to ACS. Methods: From Aug 2008 to March 2011, subjects (n=2288) were enrolled from the Kumamoto Intervention Conference Study (KICS), which is a multicenter registry, and enrolling consecutive patients undergoing PCI in 15 centers in Japan. Patients were assigned to two groups treated in hospitals with (n=1954) or without (n=334) onsite cardiac surgery. Clinical events were followed up for 12 months. Primary endpoint was in-hospital death, cardiovascular death, myocardial infarction, and stroke. And we monitored other events those were non-cardiovascular deaths, bleeding complications, revascularizations, and emergent CABG. Results: There was no overall significant difference in primary endpoint between hospitals with and without onsite cardiac surgery (9.6%vs9.5%; P=0.737). There was also no significant difference when events in primary endpoint were considered separately. In other events, only revascularization was more frequently seen in hospitals with onsite cardiac surgery (22.1%vs12.9%; P<0.001). Kaplan-Meier analysis for primary endpoint showed that there was no significant difference between two groups (Log Rank P=0.943). By cox proportional hazards model analysis for primary endpoint, without onsite cardiac surgery was not a predictive factor for primary endpoint (HR 0.969, 95%CI 0.704-1.333; P=0.845). We performed propensity score matching analysis to correct for the disparate patient numbers between two groups, and there was also no significant difference for primary endpoint (6.9% vs 8.0%; P=0.544). Conclusions: There is no significant difference in clinical outcomes following PCI for ACS between hospitals with and without onsite cardiac surgery backup in Japan.
