Urinary proteomics combined with home blood pressure telemonitoring for health care reform trial-First progress report.

High blood pressure (BP) and type-2 diabetes (T2DM) are forerunners of chronic kidney disease and left ventricular dysfunction. Home BP telemonitoring (HTM) and urinary peptidomic profiling (UPP) are technologies enabling risk stratification and personalized prevention. UPRIGHT-HTM (NCT04299529) is an investigator-initiated, multicenter, open-label, randomized trial with blinded endpoint evaluation designed to assess the efficacy of HTM plus UPP (experimental group) over HTM alone (control group) in guiding treatment in asymptomatic patients, aged 55-75 years, with ≥5 cardiovascular risk factors. From screening onwards, HTM data can be freely accessed by all patients and their caregivers; UPP results are communicated early during follow-up to patients and caregivers in the intervention group, but at trial closure in the control group. From May 2021 until January 2023, 235 patients were screened, of whom 53 were still progressing through the run-in period and 144 were randomized. Both groups had similar characteristics, including average age (62.0 years) and the proportions of African Blacks (81.9%), White Europeans (16.7%), women 56.2%, home (31.2%), and office (50.0%) hypertension, T2DM (36.4%), micro-albuminuria (29.4%), and ECG (9.7%) and echocardiographic (11.5%) left ventricular hypertrophy. Home and office BP were 128.8/79.2 mm Hg and 137.1/82.7 mm Hg, respectively, resulting in a prevalence of white-coat, masked and sustained hypertension of 40.3%, 11.1%, and 25.7%. HTM persisted after randomization (48 681 readings up to 15 January 2023). In conclusion, results predominantly from low-resource sub-Saharan centers proved the feasibility of this multi-ethnic trial. The COVID-19 pandemic caused delays and differential recruitment rates across centers.

The clinical efficacy of melatonin in the treatment of patients with COVID-19: a systematic review and meta-analysis of randomized controlled trials.

Background: The COVID-19 pandemic has resulted in significant morbidity and mortality worldwide, with cytokine storm leading to exaggerating immune response, multi-organ dysfunction and death. Melatonin has been shown to have anti-inflammatory and immunomodulatory effects and its effect on COVID-19 clinical outcomes is controversial. This study aimed to conduct a meta-analysis to evaluate the impact of melatonin on COVID-19 patients. Methods: PubMed, Embase, and Cochrane Central Register of Controlled Trials were searched without any language or publication year limitations from inception to 15 Nov 2022. Randomized controlled trials (RCTs) using melatonin as therapy in COVID-19 patients were included. The primary outcome was mortality, and the secondary outcomes included were the recovery rate of clinical symptoms, changes in the inflammatory markers like C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and neutrophil to lymphocyte ratio (NLR). A random-effects model was applied for meta-analyses, and further subgroup and sensitivity analyses were also conducted. Results: A total of nine RCTs with 718 subjects were included. Five studies using melatonin with the primary outcome were analyzed, and the pooled results showed no significant difference in mortality between melatonin and control groups with high heterogeneity across studies identified (risk ratio [RR] 0.72, 95% confidence interval [CI] 0.47-1.11, p = 0.14, I2 = 82%). However, subgroup analyses revealed statistically significant effects in patients aged under 55 years (RR 0.71, 95% CI 0.62-0.82, p < 0.01) and in patients treated for more than 10 days (RR 0.07, 95% CI 0.01-0.53, p = 0.01). The recovery rate of clinical symptoms and changes in CRP, ESR, and NLR were not statistically significant. No serious adverse effects were reported from melatonin use. Conclusion: In conclusion, based on low certainty of evidence, the study concluded that melatonin therapy does not significantly reduce mortality in COVID-19 patients, but there are possible benefits in patients under 55 years or treated for more than 10 days. With a very low certainty of evidence, we found no significant difference in the recovery rate of COVID-19 related symptoms or inflammatory markers in current studies. Further studies with larger sample sizes are warranted to determine the possible efficacy of melatonin on COVID-19 patients.

The Impact of COVID-19 on Elective Cardiovascular Procedures in Taiwan - A Single-Center Experience.

COVID-19 has reached a pandemic level and affected both individual's health and global healthcare systems. Although Taiwan has encountered a less severe COVID-19 pandemic than many other countries, it has impacted the workflow of all cardiovascular examinations and procedures. Compared to before January 21st, 2020 (the date of the first confirmed COVID-19 in Taiwan), the number of patients who have received echocardiography and cardiac catheterization has since fallen. However, the number of percutaneous coronary interventions being performed has remained at the usual level. Based on our experience, we suggest that healthcare providers in Taiwan should carefully evaluate the urgency of cardiovascular procedures and deferred non-emergent procedures. Given that the pandemic has not yet plateaued, we should remain prepared for future challenges to maintain our medical service.

Cardiovascular Complications of COVID-19 and Associated Concerns: A Review.

SARS-CoV-2 is the virus that has caused the current coronavirus disease 2019 (COVID-19) pandemic. SARS-CoV-2 is characterized by significantly affecting the cardiovascular system of infected patients. In addition to the direct injuries caused by the virus, the subsequent cytokine storm - an overproduction of immune cells and their activating compounds - also causes damage to the heart. The development of anti-SARS-CoV-2 treatments is necessary to control the epidemic. Despite an explosive growth in research, a comprehensive review of up-to-date information is lacking. Herein, we summarize pivotal findings regarding the epidemiology, complications, and mechanisms of, and recent therapies for, COVID-19, with special focus on its cardiovascular impacts.

Management of acute cardiovascular events in patients with COVID-19.

The pandemic of coronavirus disease 2019 (COVID-19) caused by the newly discovered virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), had been noticed to have high morbidity and mortality. Apart from pneumonia, COVID-19 can also cause damage to the cardiovascular system, and co-occurring with cardiovascular injury leads to a poorer prognosis. Besides, amid the pandemic of COVID-19, the management of critical cardiovascular events needs to further account for the highly infectious coronavirus, prompt and optimal treatments, clinician's safety, and healthcare provider's capacity. This review article aims to provide more comprehensive and appropriate guidance for the management of critical cardiovascular disease, including ST-segment elevation myocardial infarction (STEMI), non-STEMI acute coronary syndrome, cardiogenic shock, acute heart failure, cardiopulmonary resuscitation, and advanced care planning, during the COVID-19 epidemic.

A Double-Edged Sword-Cardiovascular Concerns of Potential Anti-COVID-19 Drugs.

Coronavirus disease 2019 (COVID-19) is a pandemic infection caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). COVID-19 significantly affects multiple systems including the cardiovascular system. Most importantly, in addition to the direct injury from the virus per se, the subsequent cytokine storm, an overproduction of immune cells and their activating compounds, causes devastating damage. To date, emerging anti-SARS-CoV-2 treatments are warranted to control epidemics. Several candidate drugs have been screened and are currently under investigation. These primarily include antiviral regimens and immunomodulatory regimens. However, beyond the anti-SARS-CoV-2 effects, these drugs may also have risks to the cardiovascular system, especially altering cardiac conduction. Herein, we review the cardiovascular risks of potential anti-COVID-19 drugs.
