Article Synopsis
  • * It compared two groups of patients with treated hypertension: one group monitored during the pandemic and another monitored before it, looking at changes in hypertension phenotypes like sustained uncontrolled hypertension (SUCH) and sustained controlled hypertension (SCH).
  • * Results showed no significant changes in the pandemic group’s hypertension phenotypes, while the pre-pandemic group saw an increase in SCH and a decrease in SUCH, suggesting the pandemic negatively impacted blood pressure management.

Article Synopsis
  • The study investigated how the COVID-19 pandemic affected blood pressure control in patients with hypertension using ambulatory blood pressure monitoring (ABPM).
  • Data were compared between two groups: patients measured before the pandemic and those measured during it, with a total of 704 pandemic patients and 916 prepandemic patients included in the analysis.
  • Results showed that during the pandemic, patients had higher blood pressure readings and a greater prevalence of uncontrolled hypertension, highlighting the need for strategies to manage blood pressure during such crises.

Objective Real-life management of patients with hypertension and chronic kidney disease (CKD) among European Society of Hypertension Excellence Centres (ESH-ECs) is unclear : we aimed to investigate it. Methods A survey was conducted in 2023. The questionnaire contained 64 questions asking ESH-ECs representatives to estimate how patients with CKD are managed.

Article Synopsis
  • - A 2023 survey by the European Society of Hypertension assessed the management of chronic kidney disease (CKD) patients with hypertension across 88 centers in 27 countries, finding that only 28% had preexisting CKD, and 30% exhibited resistant hypertension.
  • - The survey indicated inconsistent rates of recent kidney function tests and varying usage of important medications, showing higher rates of certain drugs when nephrologists were involved in the care team.
  • - Overall, the study highlighted significant gaps in CKD screening and treatment prior to referral for specialized care, suggesting that tailored initiatives could enhance management for patients with hypertension and CKD.

Background: The prognostic relevance of short-term blood pressure (BP) variability in hypertension is not clearly established. We aimed to evaluate the association of short-term BP variability, with all-cause and cardiovascular mortality in a large cohort of patients with hypertension.

Methods: We selected 59 124 patients from the Spanish Ambulatory Blood Pressure Monitoring Registry from 2004 to 2014 (median follow-up: 9.

Objective: Acknowledging the rates of endophthalmitis after cataract surgery is very important to understand the seriousness of the disease. Until now, there is no data of this situation in Argentina. The aim of this study was to estimate the incidence of postoperative endophthalmitis after cataract surgery at a tertiary hospital, a medical facility which provides a high degree of subspecialty expertise, in Buenos Aires, Argentina.

Antihypertensive drug therapy is one of the most efficient medical interventions for preventing disability and death globally. Most of the evidence supporting its benefits has been derived from outcome trials with morning dosing of medications. Accumulating evidence suggests an adverse prognosis associated with night-time hypertension, nondipping blood pressure (BP) profile and morning BP surge, with increased incidence of cardiovascular events during the first few morning hours.

Background: The role of pulse pressure (PP) 'widening' at older and younger age as a cardiovascular risk factor is still controversial. Mean PP, as determined from repeated blood pressure (BP) readings, can be expressed as a sum of two components: 'elastic PP' (elPP) and 'stiffening PP' (stPP) associated, respectively, with stiffness at the diastole and its relative change during the systole. We investigated the association of 24-h ambulatory PP, elPP, and stPP ('PP variables') with mortality and composite cardiovascular events in different age classes.

Background: Pulse pressure (PP) reflects the age-related stiffening of the central arteries, but no study addressed the management of the PP-related risk over the human lifespan.

Methods: In 4,663 young (18-49 years) and 7,185 older adults (≥50 years), brachial PP was recorded over 24 hours. Total mortality and all major cardiovascular events (MACEs) combined were coprimary endpoints.

Background & Aims: Abnormal liver tests are common in patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, but a possible direct role of the virus in liver injury and its association with short-term outcomes are controversial. Therefore, we aimed to compare the pattern of abnormal liver tests in patients with SARS-CoV-2 with those of patients infected with influenza, a non-hepatotropic respiratory virus, and their association with worse outcomes during hospitalisation.

Methods: We performed a retrospective cohort study of 1,737 hospitalised patients (865 with influenza and 872 with SARS-CoV-2) in a tertiary medical centre.

Primary central nervous system lymphoma is one of the most infrequent brain tumours, accounting for 3% of primary central nervous system neoplasms. In addition to its low prevalence, clinical presentation is usually nonspecific, leading to diagnostic delay. Intraocular involvement occurs in 15% of cases, and disease onset in this location is even rarer.

Objectives: To investigate the effect of birth weight (BW) and maternal pre-pregnancy BMI (mBMI) on blood pressure (BP) in adolescence.

Methods: A Population-based cohort of 11,729 births in Jerusalem during 1974-1976, with archival data on maternal and birth characteristics was performed. Measurements at age 17 were assessed and linear regression models were used to evaluate the associations of birth characteristics with BP outcomes.

Introduction: Tamoxifen is a non-steroidal anti-oestrogen that acts as an antagonist in breast tissue, neurosensory retina, and retinal pigment epithelium (RPE). The reported incidence of its ocular effects varies between 0.9% and 11%.

For years, physicians and scientists were enthralled by the enigmatic phenomenon of fasting-associated diuresis and natriuresis and their reversal by feeding. This abrupt response is most prominent in obese and hypertensive individuals, and if repeated once and again may lead to the attenuation of blood pressure and improve insulin sensitivity. The mechanisms involved in early natriuresis and diuresis remain speculative as the renin-angiotensin-aldosterone axis and natriuretic peptides are initially suppressed.

Objectives: Corin is a protease that converts pro-atrial natriuretic peptide (pro-ANP) to ANP. While the involvement of ANP in the cardiovascular regulation is well established, there is increasing evidence that the pregnant uterus produces ANP, which promotes spiral artery remodeling. The present study examines the alterations in corin and PCSK6, a key enzyme in the conversion of pro-corin to corin, in the placenta of hyperinsulinemic dams (HD) featuring pregnancy-induced hypertension (PIH).

Objective: Sympathoadrenal activity is decreased during overnight rest. This study assessed whether urinary-free normetanephrine, metanephrine and methoxytyramine in overnight/first-morning urine collections might offer an alternative to measurements in 24-h collections or plasma for diagnosis of pheochromocytoma and paraganglioma (PPGL).

Design And Methods: Prospective multicenter cross-sectional diagnostic study involving 706 patients tested for PPGL, in whom tumors were confirmed in 79 and excluded in 627 after follow-up.

Objective: Twenty-four-hour ambulatory pulse pressure (PP) is a powerful predictor of outcome. We attempted to apply the recently described PP components, an elastic (elPP), and systolic stiffening (stPP) components from 24-h ambulatory blood pressure (BP) monitoring (AMBP), and examine their influence on outcome in the Ohasama study population.

Design And Methods: Included were participants of the Ohasama study without history of cardiovascular disease (CVD), who were followed-up for total and CVD mortality, and for stroke morbidity.
