Ciprofloxacin for BK viremia prophylaxis in kidney transplant recipients: Results of a prospective,double‐blind,randomized, placebo‐controlled trial

In kidney transplantation, BK virus infection has historically resulted in high rates of graft dysfunction and graft loss. Unlike other opportunistic infections, no therapies have been shown to prevent BK. The purpose of the current study was to evaluate the safety and efficacy of ciprofloxacin for the prevention of BK viremia in kidney transplant recipients. Two hundred kidney transplant recipients were enrolled in a prospective, randomized, double‐blind, placebo‐controlled trial comparing a 3‐month course of ciprofloxacin (n = 133) vs placebo (n = 67) for the prevention of BK viremia. The primary endpoint of BK viremia at month 6 posttransplant occurred in 25 (18.8%) patients in the ciprofloxacin group and 5 (7.5%) in the placebo group (P = .03). Higher rates of BK viremia (23.3% vs 11.9%; P = .06) and BK nephropathy (5.8% vs 1.5%; P = .26) remained at 12 months in the ciprofloxacin group. Ciprofloxacin use was associated with a significantly higher rate of fluoroquinolone‐resistant gram‐negative infections (83.3% vs 50%; P = .04). A 3‐month course of ciprofloxacin was ineffective at preventing BK viremia in kidney transplant recipients and was associated with an increased risk of fluoroquinolone‐resistant infections.

Comparison of facemask and mouthpiece interfaces for multiple breath washout measurements

Background

Different interfaces (mouthpiece/nose clip vs. facemask) are used during multiple breath washout (MBW) tests in young children.

Clinical characteristics and outcomes in polyarticular septic arthritis

Objectives

Septic polyarthritis is rarer than septic monoarthritis, but associated with higher mortality. Septic polyarthritis may be difficult to distinguish clinically from noninfectious inflammatory arthritis. We describe one of the largest samples of septic polyarthritis with the aim of distinguishing septic monoarthritis from polyarthritis.

Haemodynamic profiles of etomidate vs propofol for induction of anaesthesia: a randomised controlled trial in patients undergoing cardiac surgery

Background

Etomidate is frequently selected over propofol for induction of anaesthesia because of a putatively favourable haemodynamic profile, but data confirming this perception are limited.

Interval robotic cytoreduction following neoadjuvant chemotherapy in advanced ovarian cancer

The objective of this study is to review our experience with robotic interval cytoreduction following neoadjuvant chemotherapy for advanced ovarian cancer. We retrospectively reviewed patients with advanced ovarian cancer treated with neoadjuvant chemotherapy (NAC) and interval robotic cytoreduction (IRC) between 2011 and 2016 at the University of Rochester Medical Center. Demographic information, chemotherapy treatment, operative results, and follow-up were extracted from medical records. Twenty-nine patients underwent IRC after a mean of 3.9 cycles of NAC. The mean operative time was 165 min with a mean EBL of 107 cc. The mean length of stay was 2.0 days. One case (3.3%) was converted to an open procedure because of extensive tumor not amenable to robotic cytoreduction. Overall, 19 (66%) patients underwent an R0 cytoreduction, 8 (28%) an optimal (<1 cm) cytoreduction, and 2 (7%) a suboptimal cytoreduction. The median overall survival was 39.7 months and median progression-free survival was 21.2 months. Interval robotic cytoreduction following NAC is feasible and may be preferable to open interval cytoreductive surgery, in specific patients, to minimize morbidity and length of hospital stay.     

Predictors of Initiation and Engagement of Cognitive Processing Therapy Among Veterans With PTSD Enrolled in Collaborative Care

Collaborative care (CC) increases access to evidence‐based pharmacotherapy and psychotherapy. The study aim was to identify the characteristics of rural veterans receiving a telemedicine‐based CC intervention for posttraumatic stress disorder (PTSD) who initiated and engaged in cognitive processing therapy (CPT) delivered via interactive video. Veterans diagnosed with PTSD were recruited from 11 community‐based outpatient clinics (N = 133). Chart abstraction identified all mental health encounters received during the 12‐month study. General linear mixed models were used to identify characteristics that predicted CPT initiation and engagement (attendance at 8 or more sessions). For initiation, higher PTSD severity according to the Clinician Administered PTSD Scale (d = ?0.39, p = .038) and opt‐out recruitment (vs. self‐referral; d = ?0.49, p = .010) were negative predictors. For engagement, major depression (d = ?1.32, p = .006) was a negative predictor whereas a pending claim for military service connected disability (d = 2.02, p = .008) was a positive predictor. In general, veterans enrolled in CC initiated and engaged in CPT at higher rates than usual care. Those with more severe symptoms and comorbidity, however, were at risk of not starting or completing CPT.     

Feasibility and acceptability of mobile phone short message service as a support for patients receiving antiretroviral therapy in rural Uganda: a cross-sectional study

Introduction

Mobile phone technologies have been promoted to improve adherence to antiretroviral therapy (ART). We studied the receptiveness of patients in a rural Ugandan setting to the use of short messaging service (SMS) communication for such purposes.

Methods

We performed a cross-sectional analysis measuring mobile phone ownership and literacy amongst patients of The AIDS Support Organisation (TASO) in Jinja, Uganda. We performed bivariate and multivariate logistic regression analyses to examine associations between explanatory variables and a composite outcome of being literate and having a mobile phone.

Results

From June 2012 to August 2013, we enrolled 895 participants, of whom 684 (76%) were female. The median age was 44 years. A total of 576 (63%) were both literate and mobile phone users. Of these, 91% (527/ 576) responded favourably to the potential use of SMS for health communication, while only 38.9% (124/319) of others were favourable to the idea (p<0.001). A lower proportion of literate mobile phone users reported optimal adherence to ART (86.4% vs. 90.6%; p=0.007). Male participants (AOR=2.81; 95% CI 1.83–4.30), sub-optimal adherence (AOR=1.76; 95% CI 1.12–2.77), those with waged or salaried employment (AOR=2.35; 95% CI 1.23–4.49), crafts/trade work (AOR=2.38; 95% CI 1.11–5.12), or involved in petty trade (AOR=1.85; 95% CI 1.09–3.13) (in comparison to those with no income) were more likely to report mobile phone ownership and literacy.

Conclusions

In a rural Ugandan setting, we found that over 60% of patients could potentially benefit from a mobile phone-based ART adherence support. However, support for such an intervention was lower for other patients.     

Bone microstructure at the distal tibia provides a strength advantage to males in late puberty: An HR‐pQCT study

Bone is a complex structure with many levels of organization. Advanced imaging tools such as high‐resolution (HR) peripheral quantitative computed tomography (pQCT) provide the opportunity to investigate how components of bone microstructure differ between the sexes and across developmental periods. The aim of this study was to quantify the age‐ and sex‐related differences in bone microstructure and bone strength in adolescent males and females. We used HR‐pQCT (XtremeCT, Scanco Medical, Geneva, Switzerland) to assess total bone area (ToA), total bone density (ToD), trabecular bone density (TrD), cortical bone density (CoD), cortical thickness (Cort.Th), trabecular bone volume (BV/TV), trabecular number (Tb.N), trabecular thickness (Tb.Th), trabecular separation (Tb.Sp), trabecular spacing standard deviation (Tb.Sp SD), and bone strength index (BSI, mg²/mm⁴) at the distal tibia in 133 females and 146 males (15 to 20 years of age). We used a general linear model to determine differences by age‐ and sex‐group and age × sex interactions (p < 0.05). Across age categories, ToD, CoD, Cort.Th, and BSI were significantly lower at 15 and 16 years compared with 17 to 18 and 19 to 20 years in males and females. There were no differences in ToA, TrD, and BV/TV across age for either sex. Between sexes, males had significantly greater ToA, TrD, Cort.Th, BV/TV, Tb.N, and BSI compared with females; CoD and Tb.Sp SD were significantly greater for females in every age category. Males' larger and denser bones confer a bone‐strength advantage from a young age compared with females. These structural differences could represent bones that are less able to withstand loads in compression in females. © 2010 American Society for Bone and Mineral Research
