BackgroundPreliminary findings suggest that web-based interventions may be effective in achieving significant weight loss and weight loss maintenance. To date only few findings within primary care patients and especially the involvement of general practitioners are available. The aim of this trial was to examine the short-term effectiveness of a web-based coaching program in combination with an accompanied telephone counselling regarding weight reduction in a primary care setting.MethodsThe study was a cluster-randomized trial with an observation period of 12 weeks. Individuals recruited by general practitioners randomized to the intervention group participated in a web-based coaching program based on education, motivation, exercise guidance, daily SMS reminding, weekly feedback through internet and active monitoring by general practitioners. Participants in the control group received usual care and advice from their practitioner without the web-based coaching program. The main outcome was weight change between admission and after 12 weeks.Results186 participants (109 intervention group, 77 control group) were recruited into study. For 76 participants from the intervention group and 72 participants from the control group weight measurements were available both at baseline and 12 weeks. Weight decreased on average by 4.2 kg in the intervention group and 1.7 kg in the control group (mean group difference 2.5 kg; 95%CI 1,1; 3,8; p < 0.001). Reductions for waist circumference and BMI were also significantly larger within intervention.ConclusionFindings of the present trial suggest that the tested web-based coaching program for weight loss is effective in short-term. Further RCT’s are desirable in order to confirm present findings in larger populations and to investigate long-term outcomes.Trial registrationGerman Register for Clinical Trials: DRKS00003067
Background The individual course of CKD may vary, and improved methods for identifying which patients will experience short-term eGFR loss are needed. Assessing urinary Dickkopf-3 (DKK3), a stress-induced tubular epithelia-derived profibrotic glycoprotein, may provide information about ongoing tubulointerstitial fibrosis and short-term eGFR loss.Methods To investigate urinary DKK3's potential as a biomarker of short-term eGFR loss (over 12 months), we prospectively assessed eGFR and urinary DKK3 levels in patients with CKD of various etiologies at baseline and annual follow-ups. We also measured urinary DKK3 in a general population sample and patients with diagnostic kidney biopsies or IgA nephropathy under treatment.Results Median urinary DKK3-to-creatinine concentration at baseline was significantly higher in patients with CKD than the general population sample (431 versus 33 pg/mg). In the CKD cohort, having a urinary DKK3-to-creatinine level .4000 pg/mg was independently and significantly associated after multiple adjustments with mean annual decline in eGFR of 7.6% over 12 months. Urinary DKK3 significantly improved prediction of kidney function decline compared with eGFR or albuminuria alone. Urinary DKK3-tocreatinine levels were related to the extent of tubulointerstitial fibrosis in kidney biopsies. In patients with IgA nephropathy, a rise in urinary DKK3 was associated with significant eGFR decline within 6 months, whereas stable or decreasing urinary DKK3 indicated a more favorable course.Conclusions Urinary DKK3 levels identify patients at high risk for eGFR decline over the next 12 months regardless of the cause of kidney injury and beyond established biomarkers, potentially providing a tool to monitor CKD progression and assess effects of interventions.
Although dysphagia is the leading symptom of EoE, HRM is able to identify esophageal motility disorders in only some EoE patients. Observed motility disorders resolve after successful treatment in almost all of these patients. Intrabolus pressure does not seem an optimal parameter for the monitoring of successful treatment response in EoE patients.
Head and neck squamous cell carcinoma (HNSCC) is a malignancy with an increasing incidence. To aid with the selection of the most appropriate therapy, biomarkers have become a specific research focus. Sec62 is involved in endoplasmic reticulum stress tolerance and cell migration, and has been identified as a novel prognostic marker for non-small cell lung cancer. In addition, Sec62 may be a promising candidate in HNSCC. Pretreatment biopsies of 35 patients with locally advanced HNSCC, who were treated with definitive chemoradiation therapy without prior surgery, were examined for the expression of Sec62 protein, as well as the expression of epidermal growth factor receptor (EGFR), p16 and survivin proteins. Immunohistological results were correlated with patient overall survival (OS) and progression-free survival (PFS) times. In the present patient cohort, 12/35 cases (34%) demonstrated strong and 8/35 cases (23%) moderate Sec62 staining intensity. Additionally, in 11/35 cases (31%), weak staining was observed, and only 4/35 cases (11%) were Sec62-negative. Notably, a high Sec62 protein level was associated with a significantly poorer OS and PFS (P=0.020 and P=0.028, respectively). Furthermore, higher nuclear survivin expression showed a weak trend for poorer OS rate (P=0.079), whilst neither cytoplasmic survivin, EGFR nor p16 influenced OS or PFS significantly. The present study indicated that Sec62 is a promising prognostic marker for HNSCC. Increased Sec62 protein expression may indicate a poorer prognosis in advanced HNSCC. As the present study was focused on patients treated by chemoradiation therapy, further studies with larger patient cohorts and alternative treatment approaches are required in order to define the prognostic value of Sec62 in HNSCC.
Our results underline a potential pathophysiological role of SDMA in CKD progression and atherosclerotic cardiovascular disease among non-dialysis CKD patients. SDMA predicts CKD progression and future atherosclerotic cardiovascular events more consistently than other methylarginines. Future experimental and clinical studies should therefore focus upon SDMA rather than upon ADMA.
