Rationale and design of BISTRO: a randomized controlled trial to determine whether bioimpedance spectroscopy guided fluid management maintains residual kidney function in incident haemodialysis patients

Background: Preserved residual kidney function (RKF) and normal fluid status are associated with better patient outcomes in incident haemodialysis patients. The objective of this trial is to determine whether using bioimpedance technology in prescribing the optimal post-dialysis weight can reduce the rate of decline of RKF and potentially improve patient outcomes. Methods/Design: 516 patients commencing haemodialysis, aged >18 with RKF of > 3 ml/min/1.73 m2 or a urine volume >500 ml per day or per the shorter inter-dialytic period will be consented and enrolled into a pragmatic, open label, randomized controlled trial. The intervention is incorporation of bioimpedance spectroscopy (BI) determination of normally hydrated weight to set a post-dialysis target weight that limits volume depletion, compared to current standard practice. Clinicians and participants will be blinded to BI measures in the control group and a standardized record capturing management of fluid status will be used in all participants. Primary outcome is preservation of residual kidney function assessed as time to anuria (≤100 ml/day or ≤200 ml urine volume in the short inter-dialytic period). A sample size of 516 was based upon a cumulative incidence of 30% anuria in the control group and 20% in the treatment group and 11% competing risks (death, transplantation) over 10 months, with up to 2 years follow-up. Secondary outcomes include rate of decline in small solute clearance, significant adverse events, hospitalization, loss of vascular access, cardiovascular events and interventions, dialysis efficacy and safety, dialysis-related symptoms and quality of life. Economic evaluation will be carried out to determine the cost-effectiveness of the intervention. Analyses will be adjusted for patient characteristics and dialysis unit practice patterns relevant to fluid management. Discussion: This trial will establish the added value of undertaking BI measures to support clinical management of fluid status and establish the relationship between fluid status and preservation of residual kidney function in incident haemodialysis patients.

The effect of oral colchicine and vitamin K1 on bone metabolism in patients with diabetes mellitus: A post-hoc analysis of a 2 × 2 factorial randomized controlled trial with \u3csup\u3e18\u3c/sup\u3eF-sodium fluoride positron emission tomography

Purpose: Diabetes mellitus (DM) confers an increased risk of fracture. Fracture risk stratification techniques are imperfect, and preventative therapies are sparse. We aimed to describe features associated with a dysfunctional bone metabolism determined by 18F-Sodium Fluoride Positron Emission Tomography (18F-NaF PET) in patients with DM and test the effects of vitamin K1 and colchicine therapy on vertebral 18F-NaF activity. Methods: This is a post-hoc analysis of a 2 × 2 factorial randomized double-blind placebo-controlled trial. Participants aged 50–80 with DM underwent 18F-NaF PET/CT imaging at baseline, 3 months of therapy with vitamin K1 (10mg/daily) or placebo, and colchicine (0.5 mg/day) or placebo and repeat 18F-NaF PET/CT. The 18F-NaF vertebral mean standardized uptake value (SUVmean) and the CT estimated bone mineral density (BMD) (in Hounsfield units) was evaluated from thoracic vertebra. Results: In total, 149 individuals (66.4 % male, mean age 65.5 ± 6.8 years) were included. Male sex (β −1.421, 95 % CI [−1.826, −1.016], p \u3c 0.001), duration of DM in years (−0.021 [−0.039, −0.002], p = 0.030) and CT estimated vertebral BMD (0.011 [0.006, 0.015], p \u3c 0.001) were independently associated with the SUVmean. The change in the SUVmean was similar between vitamin K1 or placebo groups (−0.07 ± 0.64 v 0.07 ± 0.69, p = 0.20). Participants receiving colchicine therapy had a greater reduction in the SUVmean, compared with placebo (−0.12 ± 0.72 v 0.11 ± 0.60, p = 0.039). Conclusion: 18F-NaF PET may be a useful measure of vertebral bone metabolism in people with DM. Three months of oral colchicine reduced the 18F-NaF vertebral SUVmean, whereas Vitamin K1 had no effect. The findings should be considered hypothesis generating.

Short- and long-term outcomes of intensive care patients with acute kidney disease

Background: Acute kidney disease (AKD) is a proposed definition for acute kidney injury (AKI) lasting 7 days or longer. Little has been reported regarding characteristics of patients with AKD and their short- and long-term outcomes. We describe the epidemiology and risk factors for AKD and outcomes following AKD. Methods: This retrospective observational cohort study identified patients aged 16 or older admitted to the Glasgow Royal Infirmary and Queen Elizabeth University Hospital intensive care units (ICUs) in Scotland between 1st July 2015 and 30th June 2018. Baseline serum creatinine and subsequent values were used to identify patients with de-novo kidney injury (DNKI). Patients with recovery prior to day 7 were classified as AKI; recovery at day 7 or beyond was classified as AKD. Outcomes were in-hospital and long-term mortality, and proportion of major adverse kidney events (MAKEs). Multivariable logistic regression was used to identify risk factors for AKD. A Cox proportional hazards model was used to identify factors associated with long-term outcomes. Findings: Of the 5,334 patients admitted to ICU who were assessed for DNKI, 1,620 (30·4%) suffered DNKI and of these, 403 (24·9%) met AKD criteria; 984 (60·7%) were male and the median age was 60·0 (IQR=48·0–72·0). Male sex, sepsis and lower baseline estimated glomerular filtration rate (eGFR) were associated with development of AKD. In-ICU (16·1%vs6·2%) and in-hospital (26·1%vs11·6%) mortality rates were significantly higher in AKD patients than AKI patients. Long-term survival was not different for AKD patients (HR=1·16; p-value=0·261) but AKD was associated with subsequent MAKEs (OR=1·25). Interpretation: One in four ICU patients with DNKI met AKD criteria. These patients had an increased risk of short-term mortality and long-term MAKEs. Whilst the trend for long-term survival was lower, this was not significantly different from shorter-term AKI patients. Patients with AKD during their ICU stay should be identified to initiate interventions to reduce risk of future MAKEs. Funding: No funding was associated with this study

Cross-ancestry genome-wide association analysis of corneal thickness strengthens link between complex and Mendelian eye diseases

Central corneal thickness (CCT) is a highly heritable trait associated with complex eye diseases such as keratoconus and glaucoma. We perform a genome-wide association meta-analysis of CCT and identify 19 novel regions. In addition to adding support for known connective tissue-related pathways, pathway analyses uncover previously unreported gene sets. Remarkably, >20% of the CCT-loci are near or within Mendelian disorder genes. These included FBN1, ADAMTS2 and TGFB2 which associate with connective tissue disorders (Marfan, Ehlers-Danlos and Loeys-Dietz syndromes), and the LUM-DCN-KERA gene complex involved in myopia, corneal dystrophies and cornea plana. Using index CCT-increasing variants, we find a significant inverse correlation in effect sizes between CCT and keratoconus (r =-0.62, P = 5.30 × 10-5) but not between CCT and primary open-angle glaucoma (r =-0.17, P = 0.2). Our findings provide evidence for shared genetic influences between CCT and keratoconus, and implicate candidate genes acting in collagen and extracellular matrix regulation

Bridging the Gap Between Practice Guidelines and the Therapy Room: Community-Derived Practice Adaptations for Psychological Services with Transgender and Gender Diverse Adults in the Central United States

Individuals who identify as transgender and gender diverse (TGD) are presenting at mental health clinicians’ offices with increasing frequency. Many TGD clients are seeking care related to affirming their gender identity but also may present with anxiety, depression, trauma, substance abuse, or other problems forwhich a clinician may commonly provide services. Some clinicians may hesitate to accept TGD clients into their practice if they have little specialized training to work with this population in an affirming manner, especially in more underserved areas where a generalist practice is the norm. Numerous professional associations and experts have developed guidelines for affirmative behavioral health care for TGDpeople.However, what is needed are community-informed recommendations to bridge from the official guidelines to clinicians’ in-session activities. The Trans Collaborations Practice Adaptations for Psychological Interventions for Transgender and Gender Diverse Adults are derived from iterative interviews with TGD community members and affirming mental health clinicians in the Central United States. The 12 practice adaptations are intended to guide clinicians to adapt their usual treatment approach to be TGD affirming, especially in underserved and rural areas. The practice adaptations cover numerous aspects of practice including the office setting and paperwork, understanding gender identity and incorporating it into the case conceptualization, therapist’s self-awareness, and referrals. The Trans Collaborations Practice Adaptations will help clinicians work confidently and competently with adult TGD clients, regardless of the presenting problem, to ensure TGD communities receive the best interventions for their behavioral health concerns

Short and long-term outcomes in oliguric and non-oliguric acute kidney injury in intensive care: a retrospective, post-hoc, bicentric study

Background: Patients admitted to intensive care units frequently develop acute kidney injury. There is limited research comparing outcomes between oliguric and non-oliguric acute kidney injury in this population. This study aimed to investigate the short- and long-term outcomes in oliguric and non-oliguric acute kidney injury in intensive care patients; the specific outcomes assessed were mortality and major adverse kidney events. We hypothesised that short- and long-term outcomes would be poorer in oliguric compared to non-oliguric acute kidney injury in intensive care patients. Methods: This retrospective observational cohort study utilised prospectively collected data routinely gathered during patients’ admission. All adult patients over 16 admitted to two large Scottish general adult intensive care units were included. Patients with long-term kidney replacement therapy, prior transplantation and ICU readmission were excluded. Oliguria was defined as urine output < 0.3 ml.kg⁻¹.h⁻¹ for 24 hours. Outcomes were assessed using cox-proportional hazards analyses; should its assumptions be violated, odds ratios at prespecified timepoints were undertaken. Results: Of the 2147 patients identified with de-novo acute kidney injury, 1666 had sufficient urine output data for analysis. 528 (31.7%) subjects had oliguric acute kidney injury lasting at least 24 hours. 1-year mortality was higher in oliguric patients (adjusted Hazard Ratio 1.45 [95% confidence intervals 1.02–2.12], E-value 1.93). Our data violated the proportional hazards assumption for major adverse kidney events; 1-year odds ratio for major adverse renal events was non-significant: 1.25 (95% confidence intervals 0.92–1.69). Conclusion: Our study has demonstrated that one third of patients with acute kidney injury in intensive care developed oliguria using a standardised definition of oliguria. Oliguric acute kidney injury was found to be significantly associated with higher rates of mortality from in-critical care through to 1-year post-discharge

Vitamin k-1 intake and incident diabetes in the Danish diet, cancer, and health study

Context: Observational studies have reported lower risks of type 2 diabetes with higher vitamin K1 intake, but these studies overlook effect modification due to known diabetes risk factors. Objective: To identify subgroups that might benefit from vitamin K1 intake, we examined associations between vitamin K1 intake and incident diabetes overall and in subpopulations at risk of diabetes. Methods: Participants from the prospective cohort, the Danish Diet, Cancer, and Health Study, with no history of diabetes were followed up for diabetes incidence. The association between intake of vitamin K1, estimated from a food frequency questionnaire completed at baseline, and incident diabetes was determined using multivariable-adjusted Cox proportional-hazards models. Results: In 54 787 Danish residents with a median (interquartile range) age of 56 (52-60) years at baseline, 6700 individuals were diagnosed with diabetes during 20.8 (17.3-21.6) years of follow-up. Vitamin K1 intake was inversely and linearly associated with incident diabetes (P \u3c .0001). Compared to participants with the lowest vitamin K1 intake (median:57 g/d), participants with the highest intakes (median:191 g/d) had a 31% lower risk of diabetes (HR; 95% CI, 0.69; 0.64-0.74) after multivariable adjustments. The inverse association between vitamin K1 intake and incident diabetes was present in all subgroups (namely, men and women, ever and never smokers, low and high physical activity groups, and in participants who were normal to overweight and obese), with differences in absolute risk between subgroups. Conclusion: Higher intake of foods rich in vitamin K1 was associated with a lower risk of diabetes. If the associations observed are causal, our results indicate that more cases of diabetes would be prevented in subgroups at higher risk (men, smokers, participants with obesity, and those with low physical activity)
