RESUMO

BACKGROUND: Secondary hypertension (SH) is a form of high blood pressure caused by an identifiable underlying condition. Although, it accounts for a small fraction of the overall hypertensive population, detection and management of SH is of utmost importance, because SH phenotypes carry a high cardiovascular risk and can possibly be cured by timely treatment. CONTENT: This review focuses on the endocrine causes of SH, such as primary aldosteronism, Cushing syndrome, thyroid disease, pheochromocytoma and paraganglioma, acromegaly, and rare monogenic forms. It discusses current biomarkers, analytical methods, and diagnostic strategies, highlighting advantages and limitations of each approach. It also explores the emerging -omics technologies that can provide a comprehensive and multidimensional assessment of SH and its underlying mechanisms. SUMMARY: Endocrine SH is a heterogeneous and complex condition that requires proper screening and confirmatory tests to avoid diagnostic delays and improve patient outcomes. Careful biomarker interpretation is essential due to potential interferences, variability, and method-dependent differences. Liquid chromatography-tandem mass spectrometry is a superior method for measuring low-concentration hormones and metabolites involved in SH, but it requires expertise. Omics approaches have great potential to identify novel biomarkers, pathways, and targets for SH diagnosis and treatment, especially considering its multifactorial nature.

RESUMO

In June 2023, the European Society of Hypertension (ESH) presented and published the new 2023 ESH Guidelines for the Management of Arterial Hypertension, a document that was endorsed by the European Renal Association (ERA). Following the evolution of evidence in recent years, several novel recommendations relevant to the management of hypertension in patients with chronic kidney disease (CKD) appeared in these Guidelines. These include recommendations for target office blood pressure (BP) <130/80 mmHg in most and against target office BP <120/70 mmHg in all patients with CKD; recommendations for use of spironolactone or chlorthalidone for patients with resistant hypertension with estimated glomerular filtration rate (eGFR) higher or lower than 30 mL/min/1.73 m2, respectively; use of a sodium-glucose cotransporter 2 inhibitor for patients with CKD and estimated eGFR ≥20 mL/min/1.73 m2; use of finerenone for patients with CKD, type 2 diabetes mellitus, albuminuria, eGFR ≥25 mL/min/1.73 m2 and serum potassium <5.0 mmol/L; and revascularization in patients with atherosclerotic renovascular disease and secondary hypertension or high-risk phenotypes if stenosis ≥70% is present. The present report is a synopsis of sections of the ESH Guidelines that are relevant to the daily clinical practice of nephrologists, prepared by experts from ESH and ERA. The sections summarized are those referring to the role of CKD in hypertension staging and cardiovascular risk stratification, the evaluation of hypertension-mediated kidney damage and the overall management of hypertension in patients with CKD.

RESUMO

BACKGROUND: Healthcare providers are faced with an increasing number of patients with obesity and arterial hypertension. Preventing obesity-associated hypertension and appropriately managing patients with established disease are both important. Hence, the aim of our study was to evaluate the clinical care of patients with obesity and hypertension among ESH Excellence Centres (ECs). METHODS: We conducted a cross-sectional, international 30-item survey through e-mails. RESULTS: In total, 70 representatives of ECs participated (78% men) with 66% of them practicing medicine for more than 30 years and working in well-equipped clinics. Most were internists (41%) and cardiologists (37%) and 73% reported training on the management of obese patients with hypertension. A majority weigh their patients (77%) and evaluate patients for sleep disorders (93%). However, only 47% spend more than 5min to advise for lifestyle modification in general, 59% for weight loss, 56% for salt intake and 64% for exercise. Finally, a minority of participants ask patients if they like their body (6%) or about previous attempts to lose weight (28%), evaluate 24h urinary sodium excretion rate (22%) and provide written (15%) or personalized (10%) dietary advices. If the patient suffers also from type 2 diabetes mellitus, 66% switch treatment to GLP1 receptor agonists and 60% to SGLT2 inhibitors. CONCLUSION: Most clinicians in ESH ECs are well educated regarding obesity-associated hypertension, and clinics are sufficiently equipped to manage these patients, as well. However, several deficits were reported regarding efforts to address and implement obesity specific aspects and interventions to improve care in patients with obesity and hypertension.


Hypertension and obesity still remain two of the main cardiovascular risk factors worldwide.There is a need to lower the incidence of obesity-induced hypertension, and to focus on practical guidelines for the evaluation and management of patients with obesity and hypertension.This is a web-based survey to understand the current clinical practices in assessing/managing patients with obesity and hypertension in ESH Excellence Centres.Most clinicians in ESH ECs are well educated regarding obesity-associated hypertension.Clinics are sufficiently equipped to manage these patients.Several deficits were reported regarding efforts to address and implement obesity specific aspects and interventions to improve care in patients with obesity and hypertension.

RESUMO

The 2017 American College of Cardiology/American Heart Association and 2018 European Society of Cardiology/European Society of Hypertension clinical practice guidelines for management of high blood pressure/hypertension are influential documents. Both guidelines are comprehensive, were developed using rigorous processes, and underwent extensive peer review. The most notable difference between the 2 guidelines is the blood pressure cut points recommended for the diagnosis of hypertension. There are also differences in the timing and intensity of treatment, with the American College of Cardiology/American Heart Association guideline recommending a somewhat more intensive approach. Overall, there is substantial concordance in the recommendations provided by the 2 guideline-writing committees, with greater congruity between them than their predecessors. Additional harmonization of future guidelines would help to underscore the commonality of their core recommendations and could serve to catalyze changes in practice that would lead to improved prevention, awareness, treatment, and control of hypertension, worldwide.

RESUMO

Chronic kidney disease is one of the leading causes of morbidity and mortality especially among the aged population. A decline in kidney function with ageing comparable to ageing-related processes in human kidneys has also been described in Sprague-Dawley (SD) rats. The renin-angiotensin-system (RAS) plays a pivotal role in the pathophysiology of cardiovascular and kidney disease and is a successful therapeutic target. The discovery of angiotensin-(1-7) (Ang(1-7)), mainly produced by angiotensin-converting enzyme 2 (ACE2), and its receptor MAS offered a new view on the RAS. This ACE2/Ang(1-7)/MAS axis counteracts most deleterious actions of the RAS in the kidney. In order to evaluate if activation of this axis has a protective effect in ageing-induced kidney disease we generated a transgenic rat model (TGR(SM22hACE2)) overexpressing human ACE2 in vascular smooth muscle cells. These animals showed a specific transgene expression pattern and increased ACE2 activity in the kidney. Telemetric recording of cardiovascular parameters and evaluation of kidney function by histology and urine analysis revealed no alterations in blood pressure regulation and basal kidney function in young transgenic rats when compared to young SD rats. However, with ageing, SD rats developed a decline in kidney function characterized by severe albuminuria which was significantly less pronounced in TGR(SM22hACE2) rats. Concomitantly, we detected lower mRNA expression levels of kidney damage markers in aged transgenic animals. Thus, our results indicate that vascular ACE2-overexpression protects the kidney against ageing-induced decline in kidney function, supporting the kidney-protective role of the ACE2/Ang(1-7)/MAS axis.

RESUMO

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) associates with a considerable high rate of mortality and represents currently the most important concern in global health. The risk of more severe clinical manifestation of COVID-19 is higher in males and steeply raised with age but also increased by the presence of chronic comorbidities. Among the latter, early reports suggested that arterial hypertension associates with higher susceptibility to SARS-CoV-2 infection, more severe course and increased COVID-19-related deaths. Furthermore, experimental studies suggested that key pathophysiological hypertension mechanisms, such as activation of the renin-angiotensin system (RAS), may play a role in COVID-19. In fact, ACE2 (angiotensin-converting-enzyme 2) is the pivotal receptor for SARS-CoV-2 to enter host cells and provides thus a link between COVID-19 and RAS. It was thus anticipated that drugs modulating the RAS including an upregulation of ACE2 may increase the risk for infection with SARS-CoV-2 and poorer outcomes in COVID-19. Since the use of RAS-blockers, ACE inhibitors or angiotensin receptor blockers, represents the backbone of recommended antihypertensive therapy and intense debate about their use in the COVID-19 pandemic has developed. Currently, a direct role of hypertension, independent of age and other comorbidities, as a risk factor for the SARS-COV-2 infection and COVID-19 outcome, particularly death, has not been established. Similarly, both current experimental and clinical studies do not support an unfavorable effect of RAS-blockers or other classes of first line blood pressure lowering drugs in COVID-19. Here, we review available data on the role of hypertension and its management on COVID-19. Conversely, some aspects as to how the COVID-19 affects hypertension management and impacts on future developments are also briefly discussed. COVID-19 has and continues to proof the critical importance of hypertension research to address questions that are important for global health.

RESUMO

Atherosclerotic renovascular disease (ARVD) is the most common type of renal artery stenosis. It represents a common health problem with clinical presentations relevant to many medical specialties and carries a high risk for future cardiovascular and renal events, as well as overall mortality. The available evidence regarding the management of ARVD is conflicting. Randomized controlled trials failed to demonstrate superiority of percutaneous transluminal renal artery angioplasty (PTRA) with or without stenting in addition to standard medical therapy compared with medical therapy alone in lowering blood pressure levels or preventing adverse renal and cardiovascular outcomes in patients with ARVD, but they carried several limitations and met important criticism. Observational studies showed that PTRA is associated with future cardiorenal benefits in patients presenting with high-risk ARVD phenotypes (i.e. flash pulmonary oedema, resistant hypertension or rapid loss of kidney function). This clinical practice document, prepared by experts from the European Renal Best Practice (ERBP) board of the European Renal Association (ERA) and from the Working Group on Hypertension and the Kidney of the European Society of Hypertension (ESH), summarizes current knowledge in epidemiology, pathophysiology and diagnostic assessment of ARVD and presents, following a systematic literature review, key evidence relevant to treatment, with an aim to support clinicians in decision making and everyday management of patients with this condition.

RESUMO

Diabetic kidney disease (DKD) develops in ∼40% of patients with diabetes and is the most common cause of chronic kidney disease (CKD) worldwide. Patients with CKD, especially those with diabetes mellitus, are at high risk of both developing kidney failure and cardiovascular (CV) death. The use of renin-angiotensin system (RAS) blockers to reduce the incidence of kidney failure in patients with DKD dates back to studies that are now ≥20 years old. During the last few years, sodium-glucose co-transporter-2 inhibitors (SGLT2is) have shown beneficial renal effects in randomized trials. However, even in response to combined treatment with RAS blockers and SGLT2is, the renal residual risk remains high with kidney failure only deferred, but not avoided. The risk of CV death also remains high even with optimal current treatment. Steroidal mineralocorticoid receptor antagonists (MRAs) reduce albuminuria and surrogate markers of CV disease in patients already on optimal therapy. However, their use has been curtailed by the significant risk of hyperkalaemia. In the FInerenone in reducing kiDnEy faiLure and dIsease prOgression in DKD (FIDELIO-DKD) study comparing the actions of the non-steroidal MRA finerenone with placebo, finerenone reduced the progression of DKD and the incidence of CV events, with a relatively safe adverse event profile. This document presents in detail the available evidence on the cardioprotective and nephroprotective effects of MRAs, analyses the potential mechanisms involved and discusses their potential future place in the treatment of patients with diabetic CKD.

RESUMO

Established in vitro assays for regulatory testing of skin sensitisation partly suffer from only moderate sensitivity, specificity, and predictivity when testing specific groups of chemicals. This may be due to limited biomarker response in vitro in cell types that interact as crucial players of in vivo skin sensitisation pathogenesis. Here, we propose a molecular approach to overcome this limitation. In our model, we apply genome editing and blocking of immunoregulatory molecules to increase the range of biomarker modulation by sensitising chemicals. To this end, aryl hydrocarbon receptor (AhR) knockout was done by CRISPR/Cas9 technology in THP-1 cells and combined with Programmed Cell Death-Ligand (PD-L)1 blockade. AhR-knockout THP-1 in coculture with HaCaT keratinocytes showed increased CD54 expression compared to wild type cells after stimulation with 10 µmol/L dinitrochlorobenzene (DNCB) that was further enhanced by anti-PD-L1. After stimulation of AhR-knockout THP-1 with 200 µmol/L mercaptobenzothiazol or 10 µmol/L DNCB, cocultivated Jurkat T cells significantly increased expression of T cell receptor-associated CD3. No such increase was detected after prior treatment of THP-1 with 150 µmol/L of irritant sodium lauryl sulphate. Additionally, higher levels of inflammatory cytokines MIP-3α, MIP-1ß, TNF-α, and IL-8 were found in supernatants of enhanced loose-fit co-culture based sensitisation assay (eLCSA) after substance treatment. Hence, eLCSA allowed to discriminate between sensitisers and non-sensitisers. Thus, inhibition of immunoinhibitory pathway signalling by combining AhR knockout and PD-L1 antibody blockage into an assay involving main acting cell types in skin sensitisation may increase sensitivity and specificity of such assays and allow potency derivation.

RESUMO

PURPOSE: The coronavirus disease 2019 (COVID-19) pandemic and the subsequent lockdown profoundly affected almost all aspects of daily life including health services worldwide. The established risk factors for increased blood pressure (BP) and hypertension may also demonstrate significant changes during the pandemic. This study aims to determine the impact of the COVID-19 pandemic on BP control and BP phenotypes as assessed with 24-hour ambulatory BP monitoring (ABPM). MATERIALS AND METHODS: This is a multi-centre, observational, retrospective and comparative study involving Excellence Centres of the European Society of Hypertension across Europe. Along with clinical data and office BP, ABPM recordings will be collected in adult patients with treated arterial hypertension. There will be two groups in the study: Group 1 will consist of participants who have undergone two ABPM recordings - the second one occurring during the COVID-19 pandemic, i.e. after March 2020, and the first one 9-15 months prior to the second. Participants in Group 2 will have two repeated ABPM recordings - both performed before the pandemic within a similar 9-15 month interval between the recordings. Within each group, we will analyse and compare BP variables and phenotypes (including averaged daytime and night-time BP, BP variability, dipper and non-dipper status, white-coat and masked hypertension) between the two respective ABPM recordings and compare these changes between the two groups. The target sample size will amount to least 590 participants in each of the study groups, which means a total of at least 2360 ABPM recordings overall. EXPECTED OUTCOMES: As a result, we expect to identify the impact of a COVID-19 pandemic on blood pressure control and the quality of medical care in order to develop the strategy to control cardiovascular risk factors during unpredictable global events.


What is the context?A wide range of daily activities, including health care worldwide, were deeply affected by the Coronavirus disease 2019 pandemic and the subsequent lockdown.What is new?Our multicenter study will examine the impact of the COVID-19 pandemic on blood pressure control in hypertensive patients across Europe by analysing results of 24-hour ambulatory blood pressure monitoring.What is the impact?Optimising strategies for dealing with future unpredictable global situations will depend on understanding how the pandemic affected blood pressure control.

RESUMO

PURPOSE: To describe the history of the Excellence Centre (EC) programme of the European Society of Hypertension (ESH) since the beginning in 2006, its achievements, and its future developments. MATERIALS AND METHODS: We list the number of ECs per country, the research projects performed so far, and the organisational steps needed to reshape the EC programme for the future. RESULTS: In August 2023, the ESH EC programme includes 118 registered ECs in 21 European and 7 non-European countries. Updates about the formal steps for application, re-application, transfer of EC and retirement of EC heads are given. CONCLUSIONS: The EC programme of the ESH has been a success from the beginning. Further refinements will make it fit for the next decades.

RESUMO

Perirenal adipose tissue (PRAT) surrounding the kidney is emerging as a player and novel independent risk factor in diabetic kidney disease (DKD); DKD is a complication of diabetes and is a major cause of increased cardiovascular (CV) risk and CV mortality in affected patients. We determined the effect of diabetes induction on (i) kidney and CV damage and (ii) on the expression of proinflammatory and profibrotic factors in both the PRAT and the mesenteric adipose tissue (MAT) of Munich Wistar Frömter (MWF) rats. The 16-week-old male MWF rats (n = 10 rats/group) were fed standard chow (MWF-C) or a high-fat/high-sucrose diet for 6 weeks together with low-dose streptozotocin (15 mg/kg i.p.) at the start of dietary exposure (MWF-D). Phenotyping was performed at the end of treatment through determining water intake, urine excretion, and oral glucose tolerance; use of the homeostatic model assessment-insulin resistance index (HOMA-IR) evidenced the development of overt diabetes manifestation in MWF-D rats. The kidney damage markers Kim-1 and Ngal were significantly higher in MWF-D rats, as were the amounts of PRAT and MAT. A diabetes-induced upregulation in IL-1, IL-6, Tnf-α, and Tgf-ß was observed in both the PRAT and the MAT. Col1A1 was increased in the PRAT but not in the MAT of MWF-D, whereas IL-10 was lower and higher in the PRAT and the MAT, respectively. Urinary albumin excretion and blood pressure were not further increased by diabetes induction, while heart weight was higher in the MWF-D. In conclusion, our results show a proinflammatory and profibrotic in vivo environment in PRAT induced by diabetes which might be associated with kidney damage progression in the MWF strain.

RESUMO

INTRODUCTION: Medication safety is a vital aim in older adults' pharmacotherapy. Increased morbidity and vulnerability require particularly careful prescribing. Beneath avoiding unnecessary polypharmacy and prescribing omissions, physicians have to be aware of potentially inappropriate medications (PIMs) and related outcomes to optimize older adults' drug therapy, and to reduce adverse drug events. OBJECTIVE: The aim of this study was to identify participants characteristics associated with PIM use and associations of PIM use with functional capacity with a focus on sex differences. METHODS: Multivariable logistic regression analyses of cross-sectional Berlin Aging Study II (BASE-II) data (N = 1,382, median age 69 years, interquartile range 67-71, 51.3% women) were performed with PIM classification according to the EU(7)-PIM list. RESULTS: In the overall study population, higher education was associated with lower odds of PIM use (odds ratio [OR] 0.93, confidence interval [CI] 95% 0.87-0.99, p = 0.017). Falls (OR 1.53, CI 95% 1.08-2.17, p = 0.016), frailty/prefrailty (OR 1.68, 1.17-2.41, p = 0.005), and depression (OR 2.12, CI 95% 1.32-3.41, p = 0.002) were associated with increased odds of PIM use. A better nutritional status was associated with lower odds of PIM use (OR 0.88, CI 95% 0.81-0.97, p = 0.008). In the sex-stratified analysis, higher education was associated with lower odds of PIM use in men (OR 0.90, CI 95% 0.82-0.99, p = 0.032). Frailty/prefrailty was associated with increased odds of PIM use in men (OR 2.04, CI 95% 1.18-3.54, p = 0.011) and a better nutritional status was associated with lower odds of PIM use in men (OR 0.83, CI 95% 0.72-0.96, p = 0.011). Falls in the past 12 months were related to an increased prevalence of PIM use in women (OR 1.74, CI 95% 1.10-2.75, p = 0.019). Depression was associated with a higher prevalence of PIM use in both men (OR 2.74, CI 95% 1.20-6.24, p = 0.016) and women (OR 2.06, CI 95% 1.14-3.71, p = 0.017). We did not detect sex differences regarding the overall use of drugs with anticholinergic effects, but more men than women used PIMs referring to the cardiovascular system (p = 0.036), while more women than men used PIMs referring to the genitourinary system and sex hormones (p < 0.001). CONCLUSION: We found similarities, but also differences between men and women as to the associations between PIM use and participants' characteristics and functional capacity assessments. The association of lower education with PIM use may suggest that physicians' prescribing behavior is modified by patient education, a relationship that could evolve from more critical attitudes of educated patients towards medication use. We conclude that sex differences in associations of PIM use with functional capacities might be partly attributable to sex differences in drug classes used, but not with regard to anticholinergics, as these are used to a similar extent in men and women in the cohort studied here.

RESUMO

Beta-blockers have solid documentation in preventing cardiovascular complications in the treatment of hypertension; atenolol, metoprolol, oxprenolol and propranolol demonstrate proven cardiovascular prevention in hypertension mega-trials. Hypertension is characterised by activation of the sympathetic nervous system from early to late phases, which makes beta-blockers an appropriate treatment seen from a pathophysiological viewpoint, especially in patients with an elevated heart rate. Beta-blockers represent a heterogenous class of drugs with regard to both pharmacodynamic and pharmacokinetic properties. This position is manifest by reference to another clinical context, beta-blocker treatment of heart failure, where unequivocally there is no class effect (no similar benefit from all beta-blockers); there are good and less good beta-blockers for heart failure. Analogous differences in beta-blocker efficacy is also likely in hypertension. Beta-blockers are widely used for the treatment of diseases comorbid with hypertension, in approximately 50 different concomitant medical conditions that are frequent in patients with hypertension, leading to many de facto beta-blocker first choices in clinical practice. Thus, beta-blockers should be regarded as relevant first choices for hypertension in clinical practice, particularly if characterised by a long half-life, highly selective beta-1 blocking activity and no intrinsic agonist properties.SUMMARYBeta-blockers have solid documentation in preventing cardiovascular complications in the treatment of hypertension; atenolol, metoprolol, oxprenolol and propranolol demonstrate proven cardiovascular prevention in hypertension mega-trialsHypertension is characterised by activation of the sympathetic nervous system from early to late phases, which makes beta-blockers an appropriate treatment seen from a pathophysiological viewpoint, especially in patients with an elevated heart rateBeta-blockers represent a heterogenous class of drugs with regard to both pharmacodynamic and pharmacokinetic propertiesThis position is manifest by reference to another clinical context, beta-blocker treatment of heart failure, where unequivocally there is no class effect (no similar benefit from all beta-blockers); there are good and less good beta-blockers for heart failureAnalogous differences in beta-blocker efficacy is also likely in hypertensionBeta-blockers are widely used for the treatment of diseases comorbid with hypertension, in approximately 50 different concomitant medical conditions that are frequent in patients with hypertension, leading to many de facto beta-blockers first choices in clinical practiceThese observations, in totality, inform our opinion that beta-blockers are relevant first choices for hypertension in clinical practice and this fact needs highlightingFurther, these arguments suggest European hypertension guideline downgrading of beta-blockers is not justified.

RESUMO

BACKGROUND: The Covid-19 pandemic necessitated a decrease in non-Covid-19 related diagnostic and therapeutic procedures in many countries. We explored the impact on tertiary hypertension care. METHODS: We conducted an electronic survey regarding 6 key procedures in hypertension care within the Excellence Center network of the European Society of Hypertension. RESULTS: Overall, 54 Excellence Centers from 18 European and 3 non-European countries participated. From 2019 to 2020, there were significant decreases in the median number per centre of ambulatory blood pressure monitorings (ABPM: 544/289 for 2019/2020), duplex ultrasound of renal arteries (Duplex RA: 88.5/55), computed tomographic/magnetic resonance imaging angiography of renal arteries (CT/MRI RA: 66/19.5), percutaneous angioplasties of renal arteries (PTA RA: 5/1), laboratory tests for catecholamines (116/67.5) and for renin/aldosterone (146/83.5) (p < 0.001 for all comparisons, respectively). While reductions in all assessed diagnostic and therapeutic procedures were observed in all annual 3-months periods in the comparisons between 2019 and 2020, the most pronounced reduction occurred between April and June 2020, which was the period of the first wave and the first lockdown in most affected countries. In this period, the median reductions in 2020, as compared to 2019, were 50.7% (ABPM), 47.1% (Duplex RA), 50% (CT/MRI RA), 57.1% (PTA RA), 46.9% (catecholamines) and 41.0% (renin/aldosterone), respectively. Overall differences in reduction between 3-month time intervals were statistically highly significant. CONCLUSION: Diagnostic and therapeutic procedures related to hypertension were dramatically reduced during the first year of the Covid-19 pandemic, with the largest reduction during the first lockdown. The long-term consequences regarding blood pressure control and, ultimately, cardiovascular events remain to be investigated.

RESUMO

OBJECTIVES: There is a lack of knowledge on coping with pain and sub-group specific pain-coping profiles among older home care receivers with chronic pain. To describe pain-coping strategies, identify subgroups based on cognitive and behavioral pain-coping strategies and pain-related psychological impairment and to compare these groups with regard to socio-demographic, medical, pharmacological and psychological characteristics. METHOD: Data of 212 care receivers were examined using the German pain-coping questionnaire (FESV) to determine how they cope with pain. Subgroups were identified using hierarchic agglomerative cluster analysis, using Ward's algorithm and squared Euclidean distance, and characterized using socio-demographic, medical, pharmacological and psychological parameters. Multinomial logistic regression was used to identify variables associated with the subgroups. RESULTS: Older care receivers apply cognitive and behavioral strategies to manage pain. Three subgroups were identified: Cluster 1 (25.9%) with good coping competences and little psychological impairment, Cluster 2 (40.1%) with poor coping competences and high psychological impairment, and Cluster 3 (34%) with good coping competences and high psychological impairment. Significant differences between the clusters were observed for age, pain intensity, pain-related interference, daily activities, depression and resilience. Logistic regression demonstrated that belonging to Cluster 2 was associated with the number of pain-reducing medications, depression and resilience. Belonging to Cluster 3 was significantly linked to daily activities, the number of pain medications, depression and the level of care required. CONCLUSION: Differentiating between pain-coping profiles in the group of older care receivers with chronic pain necessitates target group-specific pain-oriented psychotherapeutic interventions, which can result in improved pain management.

RESUMO

Left ventricular hypertrophy (LVH) is a major risk factor for adverse cardiovascular events. Recently, a novel candidate gene encoding the carboxypeptidase X member 2 (CPXM2) was found to be associated with hypertension-induced LVH. CPXM2 belongs to the M14 family of metallocarboxypeptidases, yet it lacks detectable enzyme activity, and its function remains unknown. Here, we investigated the impact of micro (mi)RNA-29b, miRNA-195, and miRNA-497 on the posttranscriptional expression control of CPXM2. Candidate miRNAs for CPXM2 expression control were identified in silico. CPXM2 expression in rat cardiomyocytes (H9C2) was characterized via real-time PCR, Western blotting, and immunofluorescence. Direct miRNA/target mRNA interaction was analysed by dual luciferase assay. CPXM2 was expressed in H9C2 and co-localised with z-disc associated protein PDZ and LIM domain 3 (Pdlim3). Transfection of H9C2 with miRNA-29b, miRNA-195, and miRNA-497 led to decreased levels of CPXM2 mRNA and protein, respectively. Results of dual luciferase assays revealed that miRNA-29b and miRNA-497, but not miRNA-195, directly regulated CPXM2 expression on a posttranscriptional level via binding to the 3'UTR of CPXM2 mRNA. We identified two miRNAs capable of the direct posttranscriptional expression control of CPXM2 expression in rat cardiomyocytes. This novel data may help to shed more light on the-so far-widely unexplored expression control of CPXM2 and its potential role in LVH.

RESUMO

Arterial stiffness is a major vascular complication of chronic kidney disease (CKD). The development of renal damage, hypertension, and increased pulse wave velocity (PWV) in CKD might be associated with an imbalance in bone morphogenetic proteins (BMP)-2 and BMP-7. Plasma BMP-2 and BMP-7 were determined by ELISA in CKD patients (stages I-III; n = 95) and Munich Wistar Frömter (MWF) rats. Age-matched Wistar rats were used as a control. The expression of BMP-2, BMP-7, and profibrotic and calcification factors was determined in kidney and perivascular adipose tissues (PVAT). BMP-2 was higher in stage III CKD patients compared to control subjects. BMP-7 was lower at any CKD stage compared to controls, with a significant further reduction in stage III patients. A similar imbalance was observed in MWF rats together with the increase in systolic (SBP) and diastolic blood pressure (DBP), or pulse wave velocity (PWV). MWF exhibited elevated urinary albumin excretion (UAE) and renal expression of BMP-2 or kidney damage markers, Kim-1 and Ngal, whereas renal BMP-7 was significantly lower than in Wistar rats. SBP, DBP, PWV, UAE, and plasma creatinine positively correlated with the plasma BMP-2/BMP-7 ratio. Periaortic and mesenteric PVAT from MWF rats showed an increased expression of BMP-2 and profibrotic and calcification markers compared to Wistar rats, together with a reduced BMP-7 expression. BMP-2 and BMP-7 imbalance in plasma, kidney, and PVATs is associated with vascular damage, suggesting a profibrotic/pro-calcifying propensity associated with progressive CKD. Thus, their combined analysis stratified by CKD stages might be of clinical interest to provide information about the degree of renal and vascular damage in CKD.

RESUMO

Atrial fibrillation (AF), type 2 diabetes mellitus (DM), and chronic kidney disease (CKD) are three global epidemics with significant effects on morbidity and mortality. Diabetes is a risk factor for AF, and a risk factor for thromboembolism, comorbidity, and mortality when AF is present. The pathophysiology of diabetes-related AF and interrelationships with cardiovascular events and renal events is not fully understood but is in part related to structural, electrical, electromechanical, and autonomic remodelling. The current practice guidelines offer limited recommendations on the management of patients with AF (or risk of AF) and diabetes with its own heterogeneity for the prevention of cardiovascular and renal events. This document discusses possible clinical approaches for these patients. In the last decade, there have been major improvements for the prevention of stroke in AF patients with direct oral anticoagulants, which are preferable to vitamin K antagonists for stroke prevention in DM. Because of the increased risk rate for several cardiovascular adverse events in diabetic patients, a similar relative risk reduction generally translates into greater absolute risk reduction in the diabetic population. Recent trials with non-insulin diabetes drugs using glucagon-like peptide-1 agonists and sodium-glucose cotransporter-2 inhibitors showed a significant reduction for the risk of major adverse cardiovascular events in patients with type 2 DM. Sodium-glucose cotransporter-2 inhibitors also showed a large reduction in hospitalization for heart failure and renal events, which need to be more completely evaluated in patients with AF. Mechanisms, risks, and optimal management of AF patients with DM who have or are under risk of developing heart failure or CKD are also discussed in this document. The benefits of medical therapies for these patients still need to be put into perspective, and gaps in evidence on some of these issues are likely to be addressed in future years.
