Automated office blood pressure measurements in primary care are misleading in more than one third of treated hypertensives: The VALENTINE-Greece Home Blood Pressure Monitoring study

Abstract Background This study assessed the diagnostic reliability of automated office blood pressure (OBP) measurements in treated hypertensive patients in primary care by evaluating the prevalence of white coat hypertension (WCH) and masked uncontrolled hypertension (MUCH) phenomena. Methods Primary care physicians, nationwide in Greece, assessed consecutive hypertensive patients on stable treatment using OBP (1 visit, triplicate measurements) and home blood pressure (HBP) measurements (7 days, duplicate morning and evening measurements). All measurements were performed using validated automated devices with bluetooth capacity (Omron M7 Intelli-IT). Uncontrolled OBP was defined as ≥140/90 mmHg, and uncontrolled HBP was defined as ≥135/85 mmHg. Results A total of 790 patients recruited by 135 doctors were analyzed (age: 64.5 ± 14.4 years, diabetics: 21.4%, smokers: 20.6%, and average number of antihypertensive drugs: 1.6 ± 0.8). OBP (137.5 ± 9.4/84.3 ± 7.7 mmHg, systolic/diastolic) was higher than HBP (130.6 ± 11.2/79.9 ± 8 mmHg; difference 6.9 ± 11.6/4.4 ± 7.6 mmHg, p Conclusions In primary care, automated OBP measurements are misleading in approximately 40% of treated hypertensive patients. HBP monitoring is mandatory to avoid overtreatment of subjects with WCH phenomenon and prevent undertreatment and subsequent excess cardiovascular disease in MUCH

Towards a unified vision on animal navigation

The study of animal navigation is a complex and fertile field of research: Several questions regarding how animals relate to external stimuli, integrating them to perform their everyday movement routine, have been or are being addressed in different organisms and taxa, both from the behavioural and the neuronal activity point of view. Several invertebrate model organisms are the object of studies aimed at unravelling how they navigate and their ability to precisely return to a starting point and also how navigational information is communicated to conspecifics when precise social structures are present. Also, vertebrates are studied because of the interest in their orientation abilities while migrating, homing over impressive distances and studying exploration, orientation and space recognition. Last, research on the navigation capabilities of humans pursues a better understanding of the neural architecture involved in these processes in the remarkable effort to find answers and possible solutions to impairments, lesions and diseases. However, an 'all-inclusive' vision of navigation still appears to be in its embryonic state: A better perspective could (and should) shift from a paradigm where single research teams are centred on studying navigation in a single genus or species towards a more comprehensive evolutionary-centred view, searching systematically for behavioural analogies, and possibly for homologies in neural architecture between different taxa. In this review, we introduce examples of relevant topics in animal navigation from distinct animal groups, highlighting the similar approaches of those studies, and why, in our opinion, this research field could profit from a 'new' perspective

Prevalence, awareness, treatment and control of hypertension in Greece: EMENO national epidemiological study

Objective:The evidence on the epidemiology of hypertension in Greece is limited. The prevalence and control of hypertension was assessed in randomly selected adults of the general population in Greece within the nationwide epidemiological study EMENO.Method:On the basis of 2011 census, EMENO applied a multistage stratified random sampling method involving 577 areas throughout Greece (2013-2016). Participants were assessed at home visits with standardized questionnaires, blood tests and triplicate seated blood pressure (BP) measurements (validated upper-arm automated oscillometric device Microlife BPA100 Plus). Hypertension was defined as BP at least 140/90 mmHg (average of second - third measurement) and/or use of antihypertensive drugs. Sampling weights were applied for study design and post-stratification weights to match the age/sex distribution to the general population in Greece. Nonresponse was adjusted by inverse probability weighting.Results:A total of 6006 individuals were recruited and 4699 with valid data were analysed [mean (SD) age 49.2 (18.6) years, men 48.6%, BMI 28.2 (5.7) kg/m2]. The prevalence of hypertension was 39.6% and was higher in men than women (42.7 vs. 36.5%, P < 0.001). Among patients with hypertension, 31.8% were unaware (men/women 39.2/23.6%, P < 0.001), 2.7% aware but untreated (men/women 2.9/2.5%, P = NS), 35.1% treated uncontrolled (32.1/38.3%, P < 0.01) and 30.5% treated controlled (25.8/35.6%, P < 0.001).Conclusion:The prevalence of hypertension in Greece seems to be rising and affects 40% of the adults. One-third of them are undiagnosed and only 30% are controlled with treatment. Nationwide programmes are needed to prevent hypertension and improve its awareness and control aiming at reducing the rate cardiovascular diseases. © 2021 Lippincott Williams and Wilkins.

Prevalence, awareness, treatment and control of hypertension in Greece: national epidemiological study emeno

OBJECTIVE Investigation of the prevalence, awareness, treatment and control of hypertension in Greece through the nationwide epidemiological study EMENO (2013–2016). METHOD The multi-stage stratified random sampling method was applied to select a representative sample of the adult (≥18 years) general population involving 577 areas throughout Greece. Hypertension was defined as blood pressure (BP) ≥140/90 mmHg (average of 2nd–3rd mea-surement) and or use of antihypertensive drugs. Three BP measurements were obtained using validated electronic upper-arm device. RESULTS A total of 6,006 individuals were recruited and 4,699 with complete data were analyzed with mean age 49.2±18.6 years, 48.6% men, and mean body mass index (BMI) 28.2±5.7 kg/m². The prevalence of hypertension was 39.6% (men/women 42.7/36.5%; p<0.001). Among hypertensive subjects, 31.8% were unaware, 2.7% were aware but untreated, 35.1% were treated but uncontrolled, and 30.5% treated and controlled. CONCLUSIONS The ΕΜΕΝΟ epidemiologic study in a general population sample of adults in Greece showed that the prevalence of hypertension is rising and affects 40% of the adults. Among patients with hypertension, about 1/3 are undiagnosed and less than 1/3 are controlled with treatment. Nationwide programs for the prevention, detection and control of hypertension in Greece are needed, aimed at improving BP control and preventing a rise in the incidence of cardiovascular diseases the next decades. © Athens Medical Society

Lifespan and ROS levels in different Drosophila melanogaster strains after 24 h hypoxia exposure

During recent decades, model organisms such as Drosophila melanogaster have made it possible to study the effects of different environmental oxygen conditions on lifespan and oxidative stress. However, many studies have often yielded controversial results usually assigned to variations in Drosophila genetic background and differences in study design. In this study, we compared longevity and ROS levels in young, unmated males of three laboratory wildtype lines (Canton-S, Oregon-R and Berlin-K) and one mutant line (Sod1(n1)) as a positive control of redox imbalance, under both normoxic and hypoxic (2% oxygen for 24 h) conditions. Lifespan was used to detect the effects of hypoxic treatment and differences were analysed by means of Kaplan-Meier survival curves and log-rank tests. Electron paramagnetic resonance spectroscopy was used to measure ROS levels and analysis of variance was used to estimate the effects of hypoxic treatment and to assess ROS differences between strains. We observed that the genetic background is a relevant factor involved in D. melanogaster longevity and ROS levels. Indeed, as expected, in normoxia Sod1(n1) are the shortest-lived, while the wild-type strains, despite a longer lifespan, show some differences, with the Canton-S line displaying the lowest mortality rate. After hypoxic stress these variances are amplified, with Berlin-K flies showing the highest mortality rate and most evident reduction of lifespan. Moreover, our analysis highlighted differential effects of hypoxia on redox balance/unbalance. Canton-S flies had the lowest increase of ROS level compared to all the other strains, confirming it to be the less sensitive to hypoxic stress. Sod1(n1) flies displayed the highest ROS levels in normoxia and after hypoxia. These results should be used to further standardize future Drosophila research models designed to investigate genes and pathways that may be involved in lifespan and/or ROS, as well as comparative studies on specific mutant strains
