    Abstract Objective: The aim of this review was to summarize the most common extrapulmonary manifestations in pediatric patients with COVID-19, as well as to discuss clinical, epidemiological, and pathophysiological aspects of these clinical presentations in children.
    Source of data: An extensive search of literature was performed in order to identify pediatric cases with extrapulmonary manifestations between January 1, 2020 and June 21, 2020. Generic keywords, such as "Novel coronavirus" or "Novel coronavirus 2019" or "2019 nCoV" or "COVID-19" or "SARS-CoV-2" were searched on PubMed database, associated either with age filters or generic pediatric terms.
    Summary of findings: A total of 28 articles, including 199 patients, were considered suitable to review and data extraction. The main findings were summarized in tables. The main non-pulmonary manifestations in pediatric patients, in decreasing order of frequency, were gastrointestinal, renal, cardiovascular, neurological, hematological and lymphatic, cutaneous, hepatic, ocular, olfactory, and gustatory. Multisystem impairment and Kawasaki-like disease were also described.
    Conclusions: Differences in immune response of children and variations of tissue expression of angiotensin converting enzyme 2, the virus receptor, are likely to influence clinical, epidemiological, and pathophysiological patterns of the disease.

    Abstract Telomeres are aging biomarkers, as they shorten while cells undergo mitosis. The aim of this study was to evaluate whether psychiatric disorders marked by psychological distress lead to alterations to telomere length (TL), corroborating the hypothesis that mental disorders might have a deeper impact on our physiology and aging than it was previously thought. A systematic search of the literature using MeSH descriptors of psychological distress ("Traumatic Stress Disorder" or "Anxiety Disorder" or "depression") and telomere length ("cellular senescence", "oxidative stress" and "telomere") was conducted on PubMed, Cochrane Library and ScienceDirect databases. A total of 56 studies (113,699 patients) measured the TL from individuals diagnosed with anxiety, depression and posttraumatic disorders and compared them with those from healthy subjects. Overall, TL negatively associates with distress-related mental disorders. The possible underlying molecular mechanisms that underly psychiatric diseases to telomere shortening include oxidative stress, inflammation and mitochondrial dysfunction linking. It is still unclear whether psychological distress is either a cause or a consequence of telomere shortening.

    Abstract The participating doctors of the Hygia Chronotherapy Trial (HCT) are aware of the criticisms of its published findings, which have been unjustifiably misrepresented in letters to the editors and commentaries, perhaps because of lack of understanding of the foundations of the Hygia Project, in which the HCT is nested. Thus, our purpose through this communication is to highlight the unique features of the Hygia Project and HCT in terms of: (i) organization, management, and quality control, (ii) physician training/continuing medical education, and (iii) impact on every-day primary-care clinical practice specifically improved patient care through 48 h ambulatory blood pressure monitoring to diagnose and optimally manage by bedtime hypertension chronotherapy

    Abstract Background: Congenital Anomalies of the Kidney and the Urinary Tract (CAKUT) are defined as a heterogeneous group of anomalies that resulted from defects in kidney and urinary tract embryogenesis. CAKUT have a complex etiology. Genetic, epigenetic and environmental factors have been investigated in this context. Angiotensin II is a potent vasoconstrictor and exerts an important role in kidney embryogenesis. The angiotensin-converting enzyme (ACE) converts Angiotensin I into Angiotensin II (Ang II) and ACE gene has insertion/deletion (I/D) polymorphisms that have been evaluated in several nephropathies. This study aimed to evaluate whether the I/D polymorphisms of ACE gene and the circulating levels of Ang II are associated with any CAKUT phenotype or CAKUT in general.
    Methods and results: Our study was performed with 225 pediatric patients diagnosed with CAKUT and 210 age-and-sex matched healthy controls. ACE I/D alleles were analysed by real-time polymerase chain reaction (RT-PCR). The distribution of ACE I/D polymorphisms were compared between CAKUT patients and healthy controls, as well between ureteropelvic junction obstruction (UPJO), vesicoureteral reflux (VUR), multicystic dysplastic kidney (MCDK) phenotypes and control group. No statistical association was detected between ACE I/D polymorphism and CAKUT and UPJO, VUR, and MCDK phenotypes. In a subset of 80 CAKUT patients and 80 controls, plasma levels of Ang II were measured. No significant differences were found between CAKUT patients and controls, even in regard to comparisons of UPJO, VUR and MCDK with control group.
    Conclusion: Although CAKUT is a complex disease and the ACE gene may exert a role in kidney embryogenesis, CAKUT was not associated with any ACE I/D polymorphisms nor with differences in plasma levels of Ang II in this Brazilian pediatric population.

    Abstract Reinhold Kreutz and colleagues in a recent editorial claim the Hygia Chronotherapy Trial lacks credibility because of deficient methods, thereby dismissing both the plausibility and clinical significance of its reported findings. They misstate and misrepresent crucial information, findings and conclusions unambiguously detailed in the published report of the Hygia Chronotherapy Trial. The purpose of this communication is to provide a complete rebuttal to each and every one of the misleading and scientifically unsupported claims by Kreutz et al. that calls into question their expertise to decry the merits, advantages, limitations and validity of correctly designed and conducted ambulatory blood pressure monitoring-based chronotherapy trials.

    Abstract Introduction and objectives: Ambulatory blood pressure (BP) better predicts cardiovascular disease (CVD) outcomes than office BP measurements (OBPM). Nonetheless, current CVD risk stratification models continue to rely on exclusively daytime OBPM along with traditional factors, eg, age, sex, smoking, dyslipidemia, and/or diabetes.
    Methods: Data from 19 949 participants of the primary care-based Hygia Project assessed by 48-hour ambulatory BP monitoring (ABPM) and without prior CVD events were used to compare the diagnostic accuracy, discrimination, and performance of the original Framingham risk score (RS
    Results: During the follow-up, lasting up to 12.7 years, 1854 participants experienced a primary CVD outcome of CVD death, myocardial infarction, coronary revascularization, heart failure, stroke, transient ischemic attack, angina pectoris, or peripheral artery disease. Asleep systolic BP (SBP) mean and sleep-time relative SBP decline were the only joint significant ABPM-derived predictive factors of CVD risk and were therefore used to substitute for in-clinic SBP in the RS
    Conclusions: These collective findings reveal important limitations of CVD risk stratification when based upon OBPM, as in the Framingham score, and corroborate the clinical value of around-the-clock ABPM to properly diagnose true hypertension and reliably stratify CVD vulnerability.
