Abstract Background Bloodstream infections (BSI) with methicillin-susceptible Staphylococcus aureus (MSSA) are associated with significant morbidity and mortality. The objective of our study was to determine the efficacy of synergistic treatment of daptomycin when given with either cefazolin or cloxacillin for the treatment of MSSA BSI. Methods A randomized, double blind, placebo-controlled trial was performed at two academic hospitals in Montreal, Canada. Patients ≥ 18 years of age with MSSA BSI receiving either cefazolin or cloxacillin monotherapy were considered for inclusion. In addition to the standard of care treatment, participants received a 5-day course of adjunctive daptomycin or placebo. The primary outcome was the duration of MSSA BSI in days. Results Of 318 participants screened, 115 were enrolled and 104 were included in the intention to treat analysis (median age 67 years; 34.5% female). The median duration of bacteremia was 2.04 days among patients who received daptomycin versus 1.65 days in those who received placebo (absolute difference 0.39 days, p=0.40). A modified intention to treat analysis involving participants who remained bacteremic at the time of enrollment found a median duration of bacteremia of 3.06 days among patients who received daptomycin versus 3.0 days in those who received placebo (absolute difference 0.06 days, p=0.77). Ninety-day mortality in the daptomycin arm was 18.9% vs. 17.7% in the placebo arm (p=1.0). Conclusion Among patients with MSSA bloodstream infections, the administration of adjunctive daptomycin therapy to standard of care treatment did not shorten the duration of bacteremia and should not be routinely considered.

Abstract Background Bloodstream infections (BSI) caused by methicillin-susceptible Staphylococcus aureus (MSSA) are associated with significant morbidity and mortality. The objective of our study was to determine whether daptomycin given in combination with an anti-staphylococcal beta-lactam improved outcomes in MSSA BSI. Methods A randomized, double blind, placebo-controlled trial was performed at two academic hospitals in Montreal, Canada. Patients ≥ 18 years of age with MSSA BSI receiving either cefazolin or cloxacillin monotherapy were considered for inclusion. In addition to the standard of care treatment, participants received a 5-day course of adjunctive daptomycin or placebo. The primary outcome was the duration of MSSA BSI in days.

Ninety-day mortality in the daptomycin arm was 18.9% vs. 17.7% in the placebo arm (p=1.0). There were no significant differences in the proportion of patients who developed renal failure, hepatotoxicity, or rhabdomyolysis between groups. Conclusion Among patients with MSSA BSI, the administration of adjunctive daptomycin therapy to standard of care treatment did not shorten the duration of bacteremia.

Standard Of Care Treatment

Older women with ovarian cancer have disproportionately poorer survival outcomes than their younger counterparts and receive less treatment. In order to understand where the gaps lie in the treatment of older patients, studies incorporating more detailed assessment of baseline characteristics and treatment delivery beyond the scope of most cancer registries are required. We aimed to assess the proportion of women over the age of 65 who are offered and receive standard of care for first-line ovarian cancer at two UK NHS Cancer Centres over a 5-year period (December 2009 to August 2015). Standard of care treatment was defined as a combination of cytoreductive surgery and if indicated platinum-based chemotherapy (combination or single-agent). Sixty-five percent of patients aged 65 and above received standard of care treatment. Increasing age was associated with lower rates of receiving standard of care (35% > 80 years old versus 78% of 65–69-year-olds, p = 0.000). Older women were less likely to complete the planned chemotherapy course (p = 0.034). The oldest women continue to receive lower rates of standard care compared to younger women. Once adjusted for Federation of Gynaecology and Obstetrics (FIGO) stage, Eastern Cooperative Oncology Group (ECOG) performance status and first-line treatment received, age was no longer an independent risk factor for poorer overall survival. Optimisation of vulnerable patients utilising a comprehensive geriatric assessment and directed interventions to facilitate the delivery of standard of care treatment could help narrow the survival discrepancy between the oldest patients and their younger counterparts.

Background.Despite a paucity of evidence, decolonization measures are prescribed for outpatients with recurrent Staphylococcus aureus skin and soft-tissue infection (SSTI).Objective.Compare the effectiveness of 4 regimens for eradicating S. aureus carriage.Design.Open-label, randomized controlled trial. Colonization status and recurrent SSTI were ascertained at 1 and 4 months.Setting.Barnes-Jewish and St. Louis Children's Hospitals, St. Louis, Missouri, 2007–2009.Participants.Three hundred patients with community-onset SSTI and S. aureus colonization in the nares, axilla, or inguinal folds.Interventions.Participants were randomized to receive no therapeutic intervention (control subjects) or one of three 5-day regimens: 2% mupirocin ointment applied to the nares twice daily, intranasal mupirocin plus daily 4% chlorhexidine body washes, or intranasal mupirocin plus daily dilute bleach water baths.Results.Among 244 participants with 1-month colonization data, modified intention-to-treat analysis revealed S. aureus eradication in 38% of participants in the education only (control) group, 56% of those in the mupirocin group (P = .03 vs controls), 55% of those in the mupirocin and chlorhexidine group (P = .05), and 63% off those in the mupirocin and bleach group (P = .006). Of 229 participants with 4-month colonization data, eradication rates were 48% in the control group, 56% in the mupirocin only group (P = .40 vs controls), 54% in the mupirocin and chlorhexidine group (P = .51), and 71% in the mupirocin and bleach group (P = .02). At 1 and 4 months, recurrent SSTIs were reported by 20% and 36% of participants, respectively.Conclusions.An inexpensive regimen of dilute bleach baths, intranasal mupirocin, and hygiene education effectively eradicated S. aureus over a 4-month period. High rates of recurrent SSTI suggest that factors other than endogenous colonization are important determinants of infection.Trial Registration.ClinicalTrials.gov identifier: NCT00513799.

The Impact

Abstract INTRODUCTION Release of exosomes and extracellular vesicles (EV) by glioblastomas plays key roles in modulating the tumor microenvironment and therapeutic response. Studies to date have largely focused on the impact of EV and exosomes on the recipient cell. Here, we demonstrate that EV-mediated export of a master-regulatory miRNA has fate-determining impacts on the cell releasing the EVs. METHODS microRNA (miRNA) profiling was performed using clinical glioblastoma specimens from the same patients derived pre- and post-standard of care treatment. Mechanism mediating altered miRNA homeostasis were assessed. RESULTS While the levels of nearly all miRNAs remained unchanged after standard-of-care treatment, decreased levels of few, select miRNAs were observed, including miR-603. In response to ionizing radiation (IR), but not temozolomide (TMZ), glioblastoma cell lines exhibited a time-dependent decrease in miR-603 levels. While miR-603 biogenesis and degradation remained unchanged after IR, IR induced an increase in EV-mediated export of miR-603. Profiling of miR-603 targets revealed that miR-603 repressed the insulin-like growth factor 1 (IGF1) and IGF1 receptor (IGF1R), genes required to maintain the cancer stem cell (CSC) state, as well as MGMT, the gene encoding a DNA repair protein that detoxifies temozolomide (TMZ) induced DNA damages. IR induced export of miR-603 de-repress IGF1/IGF1R to promote radiation resistance and de-repress MGMT to promote cross-resistance to TMZ and CCNU. Ectopic miR-603 expression overwhelmed cellular capacity for miR-603 export and synergized with the tumoricidal effects of IR and temozolomide (TMZ). CONCLUSIONS Radiation stimulated EV-mediated export of miR-603 to facilitate acquired resistance to IR and cross-resistance to DNA alkylating agents.

Background/AimsTo determine if selective laser trabeculoplasty (SLT) is superior to topical medication as a first-line treatment for glaucoma on quality of life (QoL) and clinical outcomes.MethodsIn this international, longitudinal, multisite randomised controlled trial, treatment naïve mild-to-moderate primary open angle or exfoliation glaucoma patients were randomised 1:1 to SLT or topical medication. Glaucoma-specific QoL (primary outcome) was measured using the Glaucoma Outcomes Assessment Tool (GOAT; 342 items, 12 domains). Secondary outcomes included rate of successful intraocular pressure (IOP) reduction (>25% reduction from baseline) and presence of ocular surface disease including conjunctival hyperaemia and eyelid erythema. Our intention-to-treat analysis was performed at months 12 and 24.ResultsOf 167 enrolled patients, 83 and 84 were randomised to SLT and topical medication, respectively; and 145 (n=75 SLT, n=70 medication) completed 24-month follow-up. While both treatment arms achieved significant within-group gains in GOAT outcomes at both endpoints, SLT patients reported a greater between-group improvement in ‘social well-being’ compared with medication patients (mean±SE=0.28±0.13; p=0.034) at 24 months. At month 24, the rate of successful IOP reduction was 18.6% (95% CI 3.0% to 34.3%, p=0.022) higher (absolute difference) in the medication compared with SLT group. More individuals in the medication group had conjunctival hyperaemia and eyelid erythema compared with SLT at 24 months.ConclusionOverall, we did not find evidence that SLT was superior to medication in improving glaucoma-specific QoL. While we found superior IOP reduction in the medication arm, eyelid erythema and conjunctival hyperaemia were more prevalent in these patients compared with the SLT group.Trial registrationACTRN12611000720910.

Objective: The aim of this study was to evaluate the effects of a manual therapy using fascial therapy on joint bleeding, joint pain and joint function in patients with hemophilic ankle arthropathy. Setting: Hemophilia patient associations. Design: Randomized, controlled trial, multicenter and intention-to-treat analysis. Participants: A total of 65 patients with hemophilic ankle arthropathy. Intervention: The experimental group ( n = 33) received one fascial therapy session per week for three weeks. The control group ( n = 32) received no treatment. Outcome measure: The primary outcome was frequency of joint bleeding measured using self-reporting. Secondary outcomes were joint pain (under load-bearing and non-load-bearing conditions) measured using the visual analog scale; joint condition was measured using the Hemophilia Joint Health Score. Outcomes were measured at baseline, posttreatment and after five months of follow-up. Results: Improvements in the frequency joint bleeding at T0, T1 and T2 were significantly higher in the experimental group (T0: mean (SD) = 1.56 (1.30); T1: mean (SD) = 0.00 (0.00); T2: mean (SD) = 0.27 (0.57)) compared to the control group (T0: mean (SD) = 1.70 (1.78); T1: mean (SD) = 0.05 (0.21); T2: mean (SD) = 0.58 (0.85)). Mean improvement of joint state after the study period was 1.74 points (±1.66) for patients in the experimental group, while the control group exhibited a joint deterioration with 0.43 points (±0.85). Ankle joint pain under load-bearing and non-load-bearing conditions improved in the experimental group with −1.72 (±1.86) and −0.50 (±1.39) points, respectively. Conclusion: The study showed that fascial therapy is favorable for patients with hemophilic ankle arthropathy.
