A U-shaped association between serum potassium (s-potassium) and short-term mortality has been reported for patients with hypertension. Less is known about the long-term prognostic implications of s-potassium and whether this relationship is modified by intensive blood pressure (BP) control. SPRINT (Systolic Blood Pressure Intervention Trial) was a randomized, controlled trial of 9361 high-risk patients aged ≥50 years without diabetes, who were allocated to intensive versus standard BP control. We investigated associations between baseline and on-treatment s-potassium and death, using Cox proportional hazards regression (including s-potassium as a time-dependent covariate) and restricted cubic splines. We further explored the effects of intensive BP control across the s-potassium spectrum. Baseline s-potassium was available in 9336 individuals, and 8473 had a measurement at 12 months. Mean baseline s-potassium was similar between the 2 treatment groups (intensive 4.21 mmol/L versus standard 4.20 mmol/L; P =0.74), but on-treatment s-potassium was lower in the intensive group (4.14 mmol/L versus 4.18 mmol/L; P =0.001). Median follow-up was 3.3 years, with 365 all-cause deaths (3.9%) and 102 cardiovascular deaths (1.1%). Baseline s-potassium had a linear association with both types of death events ( P <0.05). On-treatment potassium also had a linear association with all-cause death ( P =0.04) but not with cardiovascular death ( P =0.13). None of the associations remained significant after multivariable adjustment ( P ≥0.05). S-potassium did not modify the effect of intensive BP control ( P ≥0.05). In SPRINT, neither baseline nor on-treatment s-potassium levels were independently associated with death, and the effect of intensive BP control was not modified by s-potassium. Careful monitoring of patients on antihypertensive medications may eliminate the risks associated with abnormal s-potassium.

ObjectiveTo investigate to what extent patients with inflammatory arthritis (IA) follow recommendations given in a secondary care nurse-led cardiovascular (CV) risk screening consultation to consult their general practitioner (GP) to reduce their CV risk and whether their socioeconomic status (SES) affects adherence.MethodsAdults with IA who had participated in a secondary care screening consultation from July 2012 to July 2015, based on the EULAR recommendations, were identified. Patients were considered to have high CV risk if they had risk Systematic COronary Risk Evaluation (SCORE) ≥5%, according to the European SCORE model or systolic blood pressure ≥145 mmHg, total cholesterol ≥8 mmol/L, LDL cholesterol ≥5 mmol/L, HbA1c ≥42 mmol/mol or fasting glucose ≥6 mmol/L. The primary outcome was a consultation with their GP and at least one action focusing on CV risk factors within 6 weeks after the screening consultation.ResultsThe study comprised 1265 patients, aged 18–85 years. Of these, 336/447 (75%) of the high-risk patients and 580/819 (71%) of the low-risk patients had a GP consultation. 127/336 (38%) of high-risk patients and 160/580 (28%) of low-risk patients received relevant actions related to their CV risk, for example, blood pressure home measurement or prescription for statins, antihypertensives or antidiabetics. Education ≥10 years increased the odds for non-adherence (OR 0.58, 95% CI 0.0.37 to 0.92, p=0.02).Conclusions75% of the high-risk patients consulted their GP after the secondary care CV risk screening, and 38% of these received an action relevant for their CV risk. Higher education decreased adherence.

Abstract Background Restrictions on face-to-face contact, due to COVID-19, led to a rapid adoption of technology to remotely deliver cardiac rehabilitation (CR). Some technologies, including Active+me, were used without knowing their benefits. We assessed changes in patient activation measure (PAM) in patients participating in routine CR, using Active+me. We also investigated changes in PAM among low, moderate, and high risk patients, changes in cardiovascular risk factors, and explored patient and healthcare professional experiences of using Active+me. Methods Patients received standard CR education and an exercise prescription. Active+me was used to monitor patient health, progress towards goals, and provide additional lifestyle support. Patients accessed Active+me through a smart-device application which synchronised to telemetry enabled scales, blood pressure monitors, pulse oximeter, and activity trackers. Changes in PAM score following CR were calculated. Sub-group analysis was conducted on patients at high, moderate, and low risk of exercise induced cardiovascular events. Qualitative interviews explored the acceptability of Active+me. Results Forty-six patients were recruited (Age: 60.4 ± 10.9 years; BMI: 27.9 ± 5.0 kg.m2; 78.3% male). PAM scores increased from 65.5 (range: 51.0 to 100.0) to 70.2 (range: 40.7 to 100.0; P = 0.039). PAM scores of high risk patients increased from 61.9 (range: 53.0 to 91.0) to 75.0 (range: 58.1 to 100.0; P = 0.044). The PAM scores of moderate and low risk patients did not change. Resting systolic blood pressure decreased from 125 mmHg (95% CI: 120 to 130 mmHg) to 119 mmHg (95% CI: 115 to 122 mmHg; P = 0.023) and waist circumference measurements decreased from 92.8 cm (95% CI: 82.6 to 102.9 cm) to 85.3 cm (95% CI 79.1 to 96.2 cm; P = 0.026). Self-reported physical activity levels increased from 1557.5 MET-minutes (range: 245.0 to 5355.0 MET-minutes) to 3363.2 MET-minutes (range: 105.0 to 12,360.0 MET-minutes; P < 0.001). Active+me was acceptable to patients and healthcare professionals. Conclusion Participation in standard CR, with Active+me, is associated with increased patient skill, knowledge, and confidence to manage their condition. Active+me may be an appropriate platform to support CR delivery when patients cannot be seen face-to-face. Trial registration As this was not a clinical trial, the study was not registered in a trial registry.

Background and aims: Bleeding after endoscopic submucosal dissection (ESD) is a severe adverse event. Several methods to prevent post-ESD bleeding (PEB) have been introduced; however, they have not been widely used because of technical difficulties. We aimed to investigate whether polysaccharide hemostatic powder (PHP), which is very easy to apply, can prevent early PEB, especially in patients with high risk of PEB. Methods: This was a prospective, multicenter, randomized, open-label, controlled trial. Patients with a high risk for PEB were enrolled. Patients with gastric neoplasms in whom the resected specimen size was expected to be >40 mm and those who were regularly taking antithrombotic agents were defined as high-risk patients. Patients were randomly assigned to the PHP or control group. Results: Between May 2017 and September 2018, 143 patients were enrolled (PHP group: 73, control group: 70). The total PEB rate was 6.3% (PHP group: 5% vs. control group: 7.1%, P=0.742). There was no bleeding within 7 days after ESD in the PHP group. Continued antithrombotic use was an independent risk factor of PEB. In subgroup analysis excluding patients who continued to take antithrombotics (n=129) during ESD, the rate of PEB was tended to be lower in the PHP group than in the control group (0% vs. 6.3%, P=0.058). Conclusion: PHP did not demonstrate a significant effect on the prevention of PEB in this study. Further larger-scale, randomized controlled trials are needed to confirm this.(ClinicalTrials.gov 03169569)
