Abstract Background Prior studies have developed a chronic kidney disease–mineral and bone disorder (CKD-MBD) composite score based on combinations of calcium (Ca), phosphorus (P) and parathyroid hormone (PTH) that have been shown to be associated with an increased risk of clinical outcomes in the USA. We examined this association in a contemporary, international cohort of hemodialysis patients. Methods We studied 19 313 patients surviving ≥12 months in the Dialysis Outcomes and Practice Patterns Study Phases 3–5 (2005–15) from Europe, Canada and the USA. The CKD-MBD composite score was defined as the number of markers above target levels (P, 3.5–5.5 mg/dL; Ca, 8.4–10.2 mg/dL; PTH, 150–600 pg/mL). Using Cox models, we estimated hazard ratios (HRs) for death and a composite event (death or hospitalization), contrasting MBD 2/3 (2–3 parameters above target) with MBD 0 (all in target), adjusted for a disease risk score (DRS). Results MBD 2/3 above target was observed in 10–14% of patients across regions and was associated with greater DRS-adjusted mortality {HR 1.41 [95% confidence interval (CI) 1.10–1.82]} and composite events [HR 1.23 (95% CI 1.10–1.38)] in the USA compared with MBD 0; the mortality association was stronger for patients ≥ 65 years of age [HR 1.82 (95% CI 1.28–2.58)] compared with patients <65 years of age [HR 1.11 (95% CI 0.80–1.55)]. HRs observed in Canada and Europe were generally consistent but weaker. Estimates for MBD 2/3 outside target (above or below) were slightly lower in all regions. Conclusions Simultaneous consideration of Ca, P and PTH may help in identifying patients on dialysis with a higher risk of major clinical outcomes related to CKD-MBD.

Abstract Background and Aims Chronic kidney disease mineral and bone disorder (CKD-MBD) is characterized by abnormalities in serum calcium, phosphorus, and parathyroid hormone (PTH) and associated with morbidity and mortality. Previous publications from the Dialysis Outcomes and Practice Patterns Study (DOPPS) have demonstrated country differences in the prevalence and treatment of CKD-MBD among hemodialysis patients in participating European countries. We aim to compare the distribution of CKD-MBD related labs and treatments across countries in a contemporary population of European hemodialysis patients. Method DOPPS is an international prospective cohort study of hemodialysis patients ≥18 years of age. Patients are enrolled randomly from a representative sample of dialysis facilities within each nation at the start of each study phase. The current analysis includes n=1,701 patients from 91 facilities in the initial prevalent cross section of Europe DOPPS phase 7 (2019-present; Belgium, Germany, Italy, Spain, Sweden, UK). Results from Belgium should be considered preliminary as initial questionnaire completion is ongoing. Results The % of patients with a high PTH (>600 pg/mL) ranged from 6% in Italy to 24% in the UK, with 12-17% having high PTH in all other countries. Mean serum total calcium ranged from 8.7 in Germany to 9.1 mg/dL in the UK (Table). Mean serum phosphorus varied from 4.5 in Belgium to 5.3 mg/dL in Germany. Dialysate calcium of 2.5 mEq/L was predominant in Germany, Sweden, and the UK while 3.0 mEq/L was the most common prescription in Belgium, Italy, and Spain. Calcimimetic prescription ranged from 13% in the UK to 32% in Spain. Etelcalcetide prescription ranged from 1% in the UK to 12% in Spain and 14% in Italy. Active vitamin D prescription ranged from 27% in Belgium to 75% in Sweden. Nearly all vitamin D prescriptions were administered intravenously in Spain versus about half in Italy; in all other countries, the route of active vitamin D administration was primarily oral. Patient age and dialysis vintage varied by country, potentially contributing to some of the observed country differences in MBD marker levels and treatment practices. Conclusion CKD-MBD related abnormalities in PTH, serum phosphorus and calcium remain common in European dialysis patients, with prevalence varying considerably by country. Substantial international variation in CKD-MBD treatments was also observed in prescription of vitamin D and calcimimetics. Uptake of the relatively new calcimimetic, etelcalcetide, varied considerably by country. A detailed understanding of the effect of treatment variation on CKD-MBD marker levels and patient outcomes is needed to provide important insights for the European HD community in optimizing management of secondary hyperparathyroidism.

We investigated the clinical epidemiology of mineral bone disorder markers in prevalent hemodialysis (HD) patients in Xinjiang, the largest province in China. Data were obtained from 59 hospitals. A total of 3725 patients tracked from January 1 to December 31, 2014, were enrolled. Serum calcium (Ca) levels, phosphorus (P) levels, and intact parathyroid hormone (iPTH) levels were analyzed. Serum Ca levels were lower compared to the International Dialysis Outcomes and Practice Patterns Study (DOPPS4) and the Chinese DOPPS. The hypercalcemia rate was similar to DOPPS4 and lower than in the Chinese DOPPS. Serum P levels were higher than in DOPPS4 and lower than those in the Chinese DOPPS. Hyperphosphatemia rates were higher than DOPPS4 and lower than Chinese DOPPS. Serum iPTH levels were higher than in DOPPS4 and the Chinese DOPPS. We demonstrated higher serum P and iPTH levels in Xinjiang HD patients than in the DOPPS4 and Chinese DOPPS. In contrast, serum Ca levels were lower than the other two studies. High hypocalcemia and hyperphosphatemia rates may suggest that HD services in Xinjiang are inadequate. A multidiscipline chronic kidney disease (CKD) care program needs to be established to improve chronic kidney disease-mineral and bone disorder (CKD-MBD) target achievement in Xinjiang.

ObjectiveThe aim of this paper is to describe evolution, epidemiology and clinical outcomes of COVID-19 in subjects tested at or admitted to hospitals in North West London.DesignObservational cohort study.SettingLondon North West Healthcare NHS Trust (LNWH).ParticipantsPatients tested and/or admitted for COVID-19 at LNWH during March and April 2020Main outcome measuresDescriptive and analytical epidemiology of demographic and clinical outcomes (intensive care unit (ICU) admission, mechanical ventilation and mortality) of those who tested positive for COVID-19.ResultsThe outbreak began in the first week of March 2020 and reached a peak by the end of March and first week of April. In the study period, 6183 tests were performed in on 4981 people. Of the 2086 laboratory confirmed COVID-19 cases, 1901 were admitted to hospital. Older age group, men and those of black or Asian minority ethnic (BAME) group were predominantly affected (p<0.05). These groups also had more severe infection resulting in ICU admission and need for mechanical ventilation (p<0.05). However, in a multivariate analysis, only increasing age was independently associated with increased risk of death (p<0.05). Mortality rate was 26.9% in hospitalised patients.ConclusionThe findings confirm that men, BAME and older population were most commonly and severely affected groups. Only older age was independently associated with mortality.

Purpose The phosphoinositide-3-kinase (PI3K), phosphatase and tensin homolog (PTEN), v-akt murine thymoma viral oncogene homolog (AKT), and mammalian target of rapamycin (mTOR) signaling pathway has been implicated in resistance to several chemotherapeutic agents. In this retrospective study, we determined whether common genetic variations in this pathway are associated with clinical outcomes in esophageal cancer patients with adenocarcinoma or squamous cell carcinoma who have undergone chemoradiotherapy and surgery. Patients and Methods Sixteen tagging single nucleotide polymorphisms (SNPs) in PIK3CA, PTEN, AKT1, AKT2, and FRAP1 (encoding mTOR) were genotyped in these patients and analyzed for associations with response to therapy, survival, and recurrence. Results We observed an increased recurrence risk with genetic variations in AKT1 and AKT2 (hazard ratio [HR], 2.21; 95% CI, 1.06 to 4.60; and HR, 3.30; 95% CI, 1.64 to 6.66, respectively). This effect was magnified with an increasing number of AKT adverse genotypes. In contrast, a predictable protective effect by PTEN genetic variants on recurrence was evident. Survival tree analysis identified higher-order interactions that resulted in variation in recurrence-free survival from 12 to 42 months, depending on the combination of SNPs. Genetic variations in AKT1, AKT2, and FRAP1 were associated with survival. Patients homozygous for either of the FRAP1 SNPs assayed had a more than three-fold increased risk of death. Two genes—AKT2 and FRAP1—were associated with a poor treatment response, while a better response was associated with heterozygosity for AKT1:rs3803304 (odds ratio, 0.50; 95% CI, 0.25 to 0.99). Conclusion These results suggest that common genetic variations in this pathway modulate clinical outcomes in patients who undergo chemoradiotherapy. With further validation, these results may be used to build a model of individualized therapy for the selection of the optimal chemotherapeutic regimen.

Background: The Canadian Stroke Best Practice recommends admission of patients to a specialised stroke unit within three hours. We aimed at assessing delays in our emergency department (ED) and correlating these with medical complications and clinical outcomes. Methods: Predictors and outcomes This is a retrospective review of patients (n=353) admitted with ischemic strokes (January 2011-March 2014). We assessed the length of stay in ED, medical complications in ED and in the stroke unit, functional status (modified Rankin Scale) at discharge and survival. Results: The median delay in ED was 13.8 hours. The rate of medical complications in the ED was 14% (most common being delirium), compared to the stroke unit with 46.7% (most common being pneumonia). Worse functional outcome was correlated with diagnosis of pneumonia (standardised β coefficient=0.2, p=0.001) and presence of brain oedema in the stroke unit (standardised β coefficient=0.2, p<0.01). Increased risk of death was correlated with brain oedema (OR=649.2, 95%CI=19-2184, p<0.01) and sepsis in the stroke unit (OR=26.8, 95%CI=2.1-339, p<0.01). Conclusions: We found a significant delay in the admission of our patients from the ED to the stroke unit, which is not in keeping with the present guidelines. Medical complications were correlated with worse outcomes. Future analyses will correlate ED delays with clinical outcomes.
