Trabecular bone score in patients with chronic kidney disease.

Patients with chronic kidney disease have high risk of osteoporotic fractures. Lower trabecular bone score (TBS) was associated with poorer kidney function and higher fracture risk when kidney function was normal. Addition of TBS to The Fracture Risk Assessment Tool with bone mineral density did not improve fracture risk prediction. INTRODUCTION: We sought to determine whether trabecular bone score (TBS) either independently or adjusted for The Fracture Risk Assessment Tool (FRAX) could predict risk of major osteoporotic fractures (MOFs) in a large population-based sample of patients with all stages of chronic kidney disease (CKD). METHODS: We used population-based administrative databases to identify patients above age 20 years who had dual-energy X-ray absorptiometry (DXA) scan and serum creatinine measured within 1 year, during the years 2005 to 2010. Patients were excluded if they were on dialysis or had a functioning renal transplant. We stratified patients by estimated glomerular filtration rate (eGFR). We collected femoral neck bone mineral density (BMD), lumbar spine TBS, incident major osteoporotic fractures (MOF) and hip fractures, and other clinical characteristics. RESULTS: Among 8289 patients, there were 6224 (75.1%) with eGFR ≥ 60 mL/min/1.73 m2, 1624 (19.6%) with eGFR 30-60 mL/min/1.73 m2, and 441 (5.3%) with eGFR < 30 mL/min/1.73 m2. There were 593 patients (7.2%) with MOFs and 163 (2.0%) with hip fractures. Lower TBS score was associated with increased risk of MOF and hip fractures across all eGFR strata in unadjusted Cox proportional hazards models but after adjusting for FRAX with BMD, lower TBS was only statistically significant for MOF prediction for eGFR ≥ 60 mL/min/1.73 m2. CONCLUSION: Lower TBS scores were associated with lower eGFR and increased fracture risk in patients with eGFR ≥ 60 mL/min/1.73 m2. However, the addition of TBS to the FRAX score with BMD did not significantly improve fracture risk prediction in patients with CKD.

Putting patients at the center of kidney care transitions: PREPARE NOW, a cluster randomized controlled trial.

Care for patients transitioning from chronic kidney disease to kidney failure often falls short of meeting patients' needs. The PREPARE NOW study is a cluster randomized controlled trial studying the effectiveness of a pragmatic health system intervention, 'Patient Centered Kidney Transition Care,' a multi-component health system intervention designed to improve patients' preparation for kidney failure treatment. Patient-Centered Kidney Transition Care provides a suite of new electronic health information tools (including a disease registry and risk prediction tools) to help providers recognize patients in need of Kidney Transitions Care and focus their attention on patients' values and treatment preferences. Patient-Centered Kidney Transition Care also adds a 'Kidney Transitions Specialist' to the nephrology health care team to facilitate patients' self-management empowerment, shared-decision making, psychosocial support, care navigation, and health care team communication. The PREPARE NOW study is conducted among eight [8] outpatient nephrology clinics at Geisinger, a large integrated health system in rural Pennsylvania. Four randomly selected nephrology clinics employ the Patient Centered Kidney Transitions Care intervention while four clinics employ usual nephrology care. To assess intervention effectiveness, patient reported, biomedical, and health system outcomes are collected annually over a period of 36 months via telephone questionnaires and electronic health records. The PREPARE NOW Study may provide needed evidence on the effectiveness of patient-centered health system interventions to improve nephrology patients' experiences, capabilities, and clinical outcomes, and it will guide the implementation of similar interventions elsewhere. TRIAL REGISTRATION: NCT02722382.

Secular trends in antihyperglycaemic medication prescriptions in older adults with diabetes and chronic kidney disease: 2004-2013.

AIM: To examine how antihyperglycaemic medications were prescribed to older adults with diabetes and chronic kidney disease over the last decade. METHODS: We conducted a population-based study of 144 252 older adults with diabetes and chronic kidney disease (estimated glomerular filtration rate <60 ml/min/1.73 m(2) or receiving chronic dialysis) in Ontario, Canada. In each study quarter (3-month intervals from 1 April 2004 until 31 March 2013) we studied the proportion of treated and newly treated patients prescribed insulin, sulphonylureas, α-glucosidase inhibitors, metformin, thiazolidinediones, meglitinides and dipeptidyl peptidase-4 (DPP-4) inhibitors. We further examined prescription trends by stage of chronic kidney disease. RESULTS: The mean age of patients increased slightly (from 76 to 78 years) over the study period and the percentage with comorbidities declined. Metformin was the predominant therapy prescribed (prescribed to a mean of 56.1% of treated patients). Glyburide (glibenclamide) and thiazolidinedione prescriptions decreased (glyburide prescriptions declined from 45.5 to 9.5%, rosiglitazone from 3.6 to 0.2% and pioglitazone from 1.9 to 1.7%), while gliclazide and DPP-4 inhibitor prescriptions increased (gliclazide prescriptions increased from 0.6 to 26.4%, sitagliptin from 0 to 15.3% and saxagliptin from 0 to 2.0%). Up to 48.6% of patients with stage 3a-5 chronic kidney disease or receiving chronic dialysis were prescribed glyburide, and up to 27.6% of patients with stage 4-5 disease or receiving chronic dialysis were prescribed metformin. CONCLUSIONS: In patients with chronic kidney disease, there were trends towards safer antihyperglycaemic medication prescribing. A considerable number of patients, however, continue to receive medications that should be avoided.

Primary multilocular hydatid cyst of neck with unique presentation: a rare case report and literature review.

Hydatid cyst (HC) is a parasitic infection caused by larva form of Echinococcus. It occurs frequently in liver and lungs. Primary HC of neck is extremely rare occurrence and here we report it with unusual presentation. A 35-year-old male presented with slowly growing painless swelling in right side of neck for 6-7 years. The swelling measured 11 × 6 cm and cough impulse elicited on local examination. MRI scan revealed a multiloculated cystic lesion in neck. Fine needle aspiration cytology yielded fluid aspirate and smear showed fragment of laminated membrane, suggestive of HC. The intact cyst was removed surgically and histopathologic examination confirmed the diagnosis of HC. Both clinicians and radiologists should consider HC in differential diagnosis of head and neck swelling for proper management.

Flexible bronchoscopic removal of a three piece foreign body from a child's bronchus.

Foreign body aspiration can be a life-threatening event especially in young children because they have smaller diameters of airway lumen, moreover, the delay in the diagnosis and subsequent therapeutic intervention can further increase the risk of morbidity.(1, 2) A retained foreign body can result in inflammatory response and granulation tissue formation around the object which make the foreign body removal difficult.(3) In such situations surgical intervention is usually needed but with interventional pulmonology modalities we can restrict the need for surgery.(4) Rigid bronchoscopy under general anaesthesia is the gold standard of diagnosis and management of foreign body aspiration.(1) However, nowadays flexible bronchoscopy is more widely available and most pulmonary physicians are trained in its use so it can be used to remove such foreign bodies. We hereby report a case of a neglected foreign body which remained in the bronchus of a child for 11 days, successfully removed by flexible bronchoscopy.

Mycobacterium avium complex-associated peritonitis in a patient on continuous ambulatory peritoneal dialysis.

Continuous ambulatory peritoneal dialysis (CAPD)-associated peritonitis remains a major cause of morbidity in the dialysis population. Typically, infection is caused by gram positive bacteria and treated with empiric antibiotics. A subset of patients, however, develop culture negative peritonitis and may be infected with fungal or mycobacterial organisms. We present a case of Mycobacterium avium complex-associated peritonitis in a HIV negative patient on CAPD. Our patient suffered from technique failure and died from unrelated causes before treatment could be completed.
