Remote Patient Monitoring of Blood Pressure Is Feasible Poststroke and Can Facilitate Triage of Care

Background and Purpose:Strict blood pressure (BP) control is a universally accepted therapeutic intervention in the prevention of secondary stroke, yet this remains difficult when patients return home postinjury. This study aimed to investigate the application of the remote patient monitoring (RPM) of BP in patients after stroke, or who were at immediate risk of stroke, and the subsequent outcomes relating to triage and escalation of care.Methods:This was a single-center proof-of-concept study. Participants were patients aged 18 years and older with a diagnosis of stroke or who were at immediate risk of stroke. Patients were enrolled into the precision recovery program (PRP) and asked to assess their BP and heart rate daily and enter values into a MyCap application for the RPM program. These data were reviewed daily by an assigned PRP clinician, and weekly Zoom meetings were held with the patient. Care was triaged and escalated to a physician as indicated.Results:Twelve patients (5 [42%] female, aged mean [range] 63 [43–84] years) met the inclusion criteria and continued in the program for median (range) 136 (8–227) days. The median (range) number of excursions of BP above limits per participant was 19 (0–79) for systolic and 36 (0–104) for diastolic. A total of 16 triage events (median [range] 1 [0–3]) were initiated for escalation of care.Conclusions:This study demonstrated that RPM is feasible in patients poststroke or at immediate risk of stroke, and facilitates the triage of care when BP is elevated above recommended limits.

Determinants of Aerobic Capacity After Tricuspid Valve Replacement in Congenitally Corrected Transposition of Great Arteries

BackgroundSystemic tricuspid regurgitation and impaired aerobic capacity are common in adults with congenitally corrected transposition of great arteries (cc-TGA), but it is unknown whether systemic tricuspid valve replacement (sTVR) is associated with improvement in aerobic capacity. ObjectivesThe purpose of this study was to determine whether sTVR was associated with postoperative improvement in aerobic capacity as measured by peak oxygen consumption (VO2). MethodsThis is a retrospective cohort study of adults with cc-TGA and ≥moderate tricuspid regurgitation that underwent sTVR and exercise test pre- and post-sTVR (2003-2019). We selected a propensity-matched control group of patients with cc-TGA and ≥moderate tricuspid regurgitation that did not undergo sTVR between exercise tests. Improvement in aerobic capacity was calculated as the difference between baseline and follow-up exercise tests. ResultsThe study comprised 48 patients in each group, and both groups had similar peak VO2 at baseline. Compared to the baseline exercise test, the sTVR group had more improvement in peak VO2 (6 ± 4% vs −8 ± 3%-predicted, P = 0.001), and the factors associated with postoperative improvement in peak VO2 were baseline systolic blood pressure (<120 mm Hg), systemic right ventricular global longitudinal strain (<−16%), and preoperative peak VO2 (>60%-predicted). ConclusionsThere was an improvement in aerobic capacity after sTVR in patients with cc-TGA and severe tricuspid regurgitation. The determinants of improvement in aerobic capacity were baseline systolic blood pressure, systemic right ventricular global longitudinal strain, and preoperative peak VO2. Further studies are required to determine whether strict blood pressure control and optimal timing of sTVR based on these indices would result in improved clinical outcomes in this population.

Electroconvulsive Therapy in a Patient With Depression on Hemodialysis: A Review of the Literature.

Evidence on electroconvulsive therapy (ECT) for people receiving chronic hemodialysis has been rather scarce in the literature. We report the case of a 74-year-old male patient with major depressive disorder on chronic hemodialysis for 14 years with numerous physical complications including abdominal aortic aneurysm, ossification of the posterior longitudinal ligament, and cerebral stroke. Several antidepressant drugs failed to improve the patient, but judicious implementation of a total of 6 ECT sessions under a close liaison with medical experts brought him into remission without any notable adverse effects. In particular, flumazenil, as well as rocuronium and sugammadex, was used together with a strict control of blood pressure. We thoroughly discuss the case and provide a literature review on such topics as assessment of physical complications, medications used for anesthesia, electrode placement, and timing of hemodialysis during ECT sessions, which identified a clear need for more research on this medically challenging issue.

Non-occlusive mesenteric ischemia during acute stroke management: three case reports

BackgroundThere are many reports of non-occlusive mesenteric ischemia in patients on maintenance hemodialysis and following cardiac surgery. However, there are few reports of non-occlusive mesenteric ischemia in patients with acute stroke.Case presentationWe report three cases of non-occlusive mesenteric ischemia with onset during treatment for acute stroke. All of the patients were undergoing strict blood-pressure control, and two patients developed NOMI soon after tracheostomy when enteral nutrition had been resumed.ConclusionMany stroke patients are older adults with risk factors such as arteriosclerosis. Thus, during acute stroke management, there is a possibility that patients may develop non-occlusive mesenteric ischemia due to decreased intestinal blood flow secondary to strict blood-pressure control. This case report implicates early enteral nutrition as a potential etiopathogenic factor of non-occlusive mesenteric ischemia in patients with acute stroke.

Risk factors for nephropathy in persons with type 1 diabetes: a population-based study

AimsAlbuminuria is strongly associated with risk of renal dysfunction, cardiovascular disease and mortality. However, clinical guidelines diverge, and evidence is sparse on what risk factor levels regarding blood pressure, blood lipids and BMI are needed to prevent albuminuria in adolescents and young adults with type 1 diabetes.MethodsA total of 9347 children and adults with type 1 diabetes [mean age 15.3 years and mean diabetes duration 1.4 years at start of follow-up] from The Swedish National Diabetes Registry were followed from first registration until end of 2017. Levels for risk factors for a risk increase in nephropathy were evaluated, and the gradient of risk per 1 SD (standard deviation) was estimated to compare the impact of each risk factor.ResultsDuring the follow-up period, 8610 (92.1%) remained normoalbuminuric, 737 (7.9%) individuals developed micro- or macroalbuminuria at any time period of whom 132 (17.9% of 737) individuals developed macroalbuminuria. Blood pressure ≥ 140/80 mmHg was associated with increased risk of albuminuria (p ≤ 0.0001), as were triglycerides ≥ 1.0 mmol/L (p = 0.039), total cholesterol ≥ 5.0 mmol/L (p = 0.0003), HDL < 1.0 mmol/L (p = 0.013), LDL 3.5– < 4.0 mmol/L (p = 0.020), and BMI ≥ 30 kg/m2 (p = 0.033). HbA1c was the strongest risk factor for any albuminuria estimated by the measure gradient of risk per 1 SD, followed by diastolic blood pressure, triglycerides, systolic blood pressure, cholesterol and LDL. In patients with HbA1c > 65 mmol/mol (> 8.1%), blood pressure > 140/70 mmHg was associated with increased risk of albuminuria.ConclusionsPreventing renal complications in adolescents and young adults with type 1 diabetes need avoidance at relatively high levels of blood pressure, blood lipids and BMI, whereas very tight control is not associated with further risk reduction. For patients with long-term poor glycaemic control, stricter blood pressure control is advocated.

Importance of Vascular Function in Patients with Heart Failure with Preserved Ejection Fraction

There had been no effective cardioprotective medications for heart failure with preserved ejection fraction (HFpEF). Therefore, treatment intervention at the hypertension (HT) stage (stage A), which is a major factor in HFpEF, is necessary. In fact, the SPRINT and STEP trials reported that strict and intensive blood pressure (BP) control was useful, reducing approximately 25% of the primary endpoints, including cardiovascular events. The effectiveness of BP reduction for HFpEF after the onset of HF (stage C or D) has been reported and shown to generally follow the J-curve phenomenon. Both left ventricular systolic/diastolic dysfunction and vascular failure are related with the pathophysiology of HF. In the case of coexisting vascular failure, BP lowering treatment is effective, because it decreases the afterload. However, BP lowering treatment has been reported to increase the incidence of renal dysfunction; therefore, paying attention to the degree of association with vascular failure, and multiple organs when determining the target BP are important to consider. The decision on the target BP and the optimal choice of cardioprotective/antihypertensive medications for HF should be based on the pathologic condition.

Transient Global Cerebral Hypoperfusion as a Characteristic Cerebral Hemodynamic Pattern in the Acute Stage after Combined Revascularization Surgery for Pediatric Moyamoya Disease: N-Isopropyl-P-[123I] Iodoamphetamine Single-Photon Emission Computed Tomography Study

Introduction: Surgical revascularization prevents cerebral ischemic attack by improving cerebral blood flow (CBF) in both adult and pediatric patients with moyamoya disease (MMD). Uneven hemodynamic changes, including local cerebral hyperperfusion and remote ischemia, can cause delayed intracerebral hemorrhage and perioperative infarctions in adult MMD patients, but the characteristic hemodynamic pattern among pediatric MMD patients after revascularization surgery is poorly understood. Methods: This study included 16 consecutive pediatric MMD patients (age, 6–16 years; mean age, 11.3) undergoing superficial temporal artery-middle cerebral artery anastomosis combined with encephalo-duro-myo-synangiosis on 21 affected hemispheres. Perioperative management was conducted by aspirin administration and strict blood pressure control (110–130 mm Hg). We prospectively performed N-isopropyl-p-[¹²³I] iodoamphetamine single-photon emission computed tomography on postoperative days (POD) 1 and 7 and analyzed the temporal changes in perioperative hemodynamics. Results: Four patients (19.0%, 4/21) exhibited immediate CBF improvement from POD 1, which was classified as “immediate redistribution pattern.” In contrast, 9 (42.9%, 9/21) demonstrated transient hemispheric global hypoperfusion at POD 1 and subsequent CBF improvement at POD 7, which was defined as “transient hypoperfusion pattern.” Although 8 patients, including 4 with “transient hypoperfusion pattern” (44.4, 4/9), developed mild transient neurological deterioration in the acute stage, it resolved in all 21 patients, and there were no permanent neurological deficits. Discussion/Conclusions: This study revealed that the “transient hypoperfusion pattern” after revascularization surgery is relatively common among pediatric MMD patients, and its outcome is favorable under strict perioperative management.

Factors Associated with Nonachievement of Target Blood Pressure in Patients on Antithrombotic Therapy: A Real-World Study.

Introduction: The current guidelines for managing hypertension recommend strict blood pressure (BP) control to prevent bleeding complications in patients with hypertension on antithrombotic therapy. However, the target BP value of <130/80 mmHg is achieved in a small proportion of these patients. This study aimed to examine the factors associated with nonachievement of target BP value (≥130/80 mmHg) in patients on antithrombotic therapy. Methods: This retrospective study was conducted at an outpatient clinic in 2018. Clinical parameters were obtained from the center’s electronic medical database. Office BP was measured once in the sitting position. A target BP value of <130/80 mmHg was defined according to the Japanese Society of Hypertension Guidelines for the Management of Hypertension 2019. Results: Of the 26,803 outpatients who had scheduled visits during this time, 2,427 received antithrombotic therapy. Patients with chronic kidney disease stage 5 or on hemodialysis and those with missing data on body mass index were excluded from the study; eventually, 2,201 outpatients met the inclusion criteria. BP values of <140/90 mmHg were observed in 59.2% of these outpatients; however, only 30.6% displayed the target BP value of <130/80 mmHg. Univariate and multivariate logistic regression analyses indicated that male gender and obesity significantly correlated with nonachievement of the target BP (≥130/80 mmHg). However, heart failure and ischemic heart disease were negatively but significantly related to nonachievement of the target BP. Conclusions: The target BP value was achieved in only a small proportion of the patients treated with antithrombotic drugs. In patients on antithrombotic therapy, obesity appeared to be a modifiable risk factor, whereas cardiovascular comorbidities, such as heart failure, were negative factors contributing to nonachievement of the target BP.

Is the KDIGO Systolic Blood Pressure Target

Meticulous management of hypertension is important in chronic kidney disease (CKD) to reduce the risk of cardiovascular disease, mortality, and progression of CKD. The recently published Kidney Disease Improving Global Outcomes (KDIGO) guideline on blood pressure (BP) management in CKD stresses the importance of standardized BP measurement and strict control of BP. This is a useful document that will help to improve the management of hypertension in CKD globally. However, the recommendation of systolic BP target of <120 mm Hg by KDIGO is controversial. It is based on weak evidence derived mainly from a single randomized controlled trial and its CKD subgroup analysis. Here, we review the current evidence surrounding BP target in CKD. We argue that the target recommended by KDIGO is not generalizable to the majority of people with CKD. Standardized BP measurements are challenging to implement outside specialist hypertension and research clinics, and the target of <120 mm Hg BP systolic cannot be extrapolated to routine clinic BP measurements. If applied to routine BP measurement, this target will expose the multimorbid and frail CKD patients to the risk of adverse events including falls and fractures. Furthermore, it will not be achievable in the majority of CKD patients. The target recommended by KDIGO is an outlier among contemporary major international hypertension guidelines and is likely to perplex clinicians. We believe the KDIGO-recommended target systolic BP <120 mm Hg for CKD is inappropriate in the majority of CKD patients and it may even be harmful for patients managed in routine clinical practice.

Prognostic Implications of Progressive Systemic Ventricular Dysfunction in Congenitally Corrected Transposition of Great Arteries

ObjectivesThe purpose of this study was to determine the risk factors for and prognostic implications of progressive right ventricular systolic dysfunction (RVD) in adults with congenitally corrected transposition of great arteries. BackgroundThere are no effective therapies for RVD; hence the need to identify and modify risk factors for progressive RVD. MethodsRV systolic function was assessed by using RV longitudinal strain (RV-LS). The first echocardiogram (baseline echocardiogram) and all subsequent annual echocardiograms performed within 5 years from the baseline echocardiogram were analyzed. Progressive RVD (temporal decline in RV-LS) was assessed as the average annual change in RV-LS within 5 years of imaging follow-up. ResultsOf 186 patients (mean age 40 ± 12 years), the RV-LS at baseline was –17% ± 4%, and the annual decline in RV-LS was –4% (95% CI: –6 to –2). The risk factors for progressive RVD were left ventricular (LV) systolic dysfunction, LV pacing, and systemic hypertension. Cardiovascular events (heart failure hospitalization, heart transplant, and death) occurred in 57 (27%) patients. Progressive RVD was associated with cardiovascular events, independent of RV systolic function at baseline. In subgroup analyses assessing impact of therapies (medical therapy, cardiac resynchronization therapy, and tricuspid valve replacement), only tricuspid valve replacement was associated with improvement in RV systolic function when performed before onset of RVD. ConclusionsPatients with congenitally corrected transposition of great arteries were at risk for progressive RVD, and the risk factors for progressive RVD were LV pacing, systemic hypertension, and concomitant LV dysfunction. Further studies are required to determine whether strict blood pressure control and early tricuspid valve replacement will prevent progressive RVD.

Abstract 13849: Association of Optimal Blood Pressure and Risk of Atrial Fibrillation in Aged Type 2 Diabetes Mellitus Patients: From the JPAD Cohort Study

Introduction: Even, both type 2 diabetes (T2DM) and hypertension are important risk factors for nonvalvular atrial fibrillation (NVAF), the efficacy of strict blood pressure control for prevention of NVAF have not been established. Hypothesis: We assessed the hypothesis that optimal blood pressure is associated with lower risk of NVAF among T2DM patients in long term cohort of aged Japanese T2DM patients, JPAD cohort study. Methods: The JPAD cohort study was a follow-up cohort study of the JPAD trial, which was a randomized, standard-care controlled trial examining whether low-dose aspirin prevented cardiovascular disease (CVD) events in 2535 Japanese patients with T2DM from 2002. After that trial ended in 2008, we followed up the patients until 2019. Optimal blood pressured was defined as systolic blood pressure &lt; 120 mm Hg at baseline regardless of use of antihypertensive drugs. The association of optimal blood pressure and risk of NVAF was evaluated by Cox proportional hazard model adjusted for conventional risk factors for CVD. We also performed subgroup analysis by use of antihypertensive drugs. Results: Mean age of participants was 65 ± 10 years. During the median follow up of 10.9 years, 132 patients developed NVAF. The adjusted hazard ratio (HR) and its 95% confidence interval (CI) of NVAF of T2DM patients with optimal blood pressure comparing to those with higher blood pressure was 0.89 (0.45-1.75). In subgroup analysis by use of antihypertensive drugs, the results were not altered. The risk of NVAF among patients with optimal blood pressure comparing to those with higher blood pressure among patients using antihypertensive drugs and those not using antihypertensive drugs were 1.08 (0.34-3.45) and 0.78 (0.34-1.79), respectively. Conclusions: Optimal blood pressure was not associated with lower risk of NVAF among aged T2DM patients. However, due to high risk profile of NVAF among aged T2DM patents, careful follow up may be still necessary for prevention of CVD.

Proposal of a new classification: "sealed type" postinfarction left ventricular free wall rupture.

Postinfarction leftventricular free wall rupture (FWR) has been classified into blow-out type and oozing type. However, considering past papers, oozing type included the cases in which the bleeding had spontaneously stopped or sealed, and the distinction between blow-out type and oozing type was not always clear. We classified FWR into the BO type (combination of blow-out type and oozing type) with continuous bleeding and sealed type and clarified the pathophysiology of the sealed type. Thirty-five patients who underwent surgical treatment for FWR during the past 21years were retrospectively evaluated. Twenty-one patients (60%) were sealed. Comparing the sealed type with the BO type, the incidence of sudden collapse with acute onset was significantly lower (sealed type; 62%, BO type; 100%, P = 0.0118), and there were more cases of transport from outside the hospital (76%, 43%, P = 0.0453). Significantly few cases had electro-mechanical dissociation immediately before surgery (10%, 71%, P = 0.0001). In the sealed type, median sternotomy was performed in 9 patients (43%), and subxiphoid drainage was performed in 12 (57%). Fifteen patients (71%) were supported by IABP postoperatively, and re-rupture occurred in 3 patients without IABP. Long-term outcomes were significantly better in the sealed type than in the BO type. Sixty percent of postinfarction ventricular free wall rupture was the sealed type. Median sternotomy and sutureless repair with postoperative IABP support were reliable treatments. Subxiphoid drainage and strict blood pressure control with IABP may be acceptable surgical strategies in elderly, frail patients.

Severity of diabetic retinopathy and its relationship with age at onset of diabetes mellitus in India: A multicentric study.

Purpose:To present clinical profile and risk factors of sight-threatening diabetic retinopathy (STDR) among people with age of onset of diabetes (AOD) <25 versus ≥25 years.Methods:A retrospective chart analysis of consecutive patients with diabetic retinopathy (DR) n = 654) treated at 14 eye care centers across India between 2018 and 2019 was performed. Patients were divided into two groups, Group 1: AOD <25 years and Group 2: AOD ≥25 years. DR and diabetic macular edema (DME) were classified using the International Clinical Classification of DR severity scale. STDR included severe nonproliferative DR (NPDR), proliferative DR (PDR), and moderate to severe DME. A multilevel mixed-effects model was used for comparison between two groups: 1) Patients with DR and AOD <25 years and 2) Patients with DR and AOD ≥25 years. Bivariate and multivariate regression analyses were used to evaluate risk factors between the two groups.Results:A total of 654 patients were included, 161 (307 eyes) in AOD <25 and 493 (927 eyes) in AOD >25 group. There was a higher prevalence of PDR with high-risk characteristics in AOD <25 group (24% vs. 12%) at baseline and 12-month follow-up (25% vs. 6%); P < 0.001. Systolic hypertension and poor glycemic control were risk factors in both groups, with no difference in these modifiable risk factors between groups.Conclusion:People with youth-onset DM are likely to present with severer form of STDR despite similar modifiable risk factors. Therefore, strict control of systolic blood pressure, glycemic status, and regular screening for DR are recommended to reduce the risk of STDR irrespective of the age of onset of diabetes.

The Impact of Secondary Hypertension in Pregnancy on Maternal and Fetal Outcomes: A 42-Month Observational Study from South India.

To examine the prevalence, etiology, and clinical outcomes of secondary hypertension in pregnancy in a high-risk tertiary care hospital. This retrospective study used data from patient records between January 2015 and July 2018. Of 52,293 pregnant women admitted during this period, those with hypertension were included. Patient demographics, diagnosis of secondary hypertension, investigations, suspected etiologies of secondary hypertension, maternal and neonatal outcomes and discharge conditions were included. The prevalence of secondary hypertension and causes were measured. Univariate followed by multivariate analyses were done to look for associated maternal and neonatal outcomes. Among patients with chronic hypertension in pregnancy, 13.7% had secondary causes, of which renal and cardiac causes were the commonest. The incidence of severe pre-eclampsia (40.5%) among patients with secondary hypertension was higher in patients with systolic blood pressures more than 140mm of Hg than in those with systolic blood pressures lower than 140mm of Hg (odds ratio [OR]: 4.92, confidence interval [CI]: 1.7-14.16, p: 0.002) irrespective of etiology. Pre-eclampsia predisposed to maternal acute kidney injury (OR: 1.23, CI: 1.04-1.45, p: 0.003), low birthweight (OR: 4.69, CI: 1.44-11.9, p: 0.006), preterm delivery (OR: 4.69, CI: 1.78-12.34, p: 0.001), and neonatal death (OR: 5.19, CI: 0.97-27.6, p: 0.04). The prevalence of hypertension in pregnancy was 10.3%; among them, the prevalence of secondary hypertension was 1.46%. Uncontrolled secondary hypertension was associated with poor maternal and neonatal outcomes. Strict control of blood pressure in secondary hypertension in pregnancy ensured better outcomes.

The ClearSight System for Postoperative Arterial Blood Pressure Monitoring After Carotid Endarterectomy: A Validation Study.

BACKGROUNDThe majority of postoperative events in patients undergoing carotid endarterectomy (CEA) are of hemodynamic origin, requiring preventive strict postoperative arterial blood pressure (BP) control. This study aimed to assess whether BP monitoring with noninvasive beat-to-beat ClearSight finger BP (BPCS) can replace invasive beat-to-beat radial artery BP (BPRAD) in the postoperative phase.METHODSThis study was a single-center clinical validation study using a prespecified study protocol. In 48 patients with symptomatic carotid artery stenosis, BPCS and BPRAD were monitored ipsilateral in a simultaneous manner during a 6-hour period on the recovery unit following CEA. Primary endpoints were accuracy and precision of BP derived by ClearSight (Edward Lifesciences, Irvine, CA) vs. the reference standard (Arbocath 20 G, Hospira, Lake Forest, IL) to investigate if BPCS is a reliable noninvasive alternative for BP monitoring postoperatively in CEA patients. Validation was guided by the standard set by the Association for Advancement of Medical Instrumentation (AAMI), considering a BP-monitor adequate when bias (precision) is <5 (8) mm Hg. Secondary endpoint was percentage under- and overtreatment, defined as exceedance of individual postoperative systolic BP threshold by BPRAD or BPCS in contrast to BPCS or BPRAD, respectively.RESULTSThe bias (precision) of BPCS compared to BPRAD was −10 (13.6), 8 (7.2) and 4 (7.8) mm Hg for systolic, diastolic and mean arterial pressure (MAP), respectively. Based on BPCS, undertreatment was 5.6% and overtreatment was 2.4%; however, percentages of undertreatment quadrupled for lower systolic BP thresholds.CONCLUSIONSNoninvasive MAP, but not systolic and diastolic BP, was similar to invasive BPRAD during postoperative observation following CEA, based on AAMI criteria. However, as systolic BP is currently leading in postoperative monitoring to adjust BP therapy on, BPCS is not a reliable alternative for BPRAD.

Особенности поражения почек при системных заболеваниях соединительной ткани

Системные заболевания соединительной ткани (СЗСТ) — достаточно большая гетерогенная группа заболеваний, имеющих определенные характерные клинические проявления и нарушения иммунорегуляции, приводящие к образованию аутоантител. Субклинические или явные признаки вовлечения почек имеют значительное усугубляющее влияние на клиническое течение СЗСТ. Нарушение функции почек характерно для таких СЗСТ, как системная красная волчанка (СКВ), ревматоидный артрит (РА), системная склеродермия, синдром Шегрена, аутоиммунные миопатии (дерматомиозит и полимиозит). На современном этапе, учитывая доступность многих диагностических манипуляций и возможности этиопатогенетического лечения, терапевтам, ревматологам и нефрологам необходимо своевременно заподозрить наличие заболевания почек у пациентов с СЗСТ и принять необходимые меры по диагностике и лечению. Современные стратегии классификации и лечения СКВ скорректированы с учетом результатов биопсии почек, что значительно улучшило прогноз поражения почек при этом заболевании. Одно из наиболее тяжелых поражений почек у пациентов с СЗСТ — это почечный склеродермический криз (ПСК), характеризующийся тяжелой гипертонией, прогрессирующим снижением функции почек и тромботической микроангиопатией, своевременное назначение ингибиторов ангиотензинпревращающего фермента таким пациентам показывает значительный эффект в борьбе с ПСК. Контроль активности основного заболевания улучшает функцию почек у большинства пациентов с синдромом Шегрена, аутоиммунными миопатиями и РA. С другой стороны, хроническое использование иммунодепрессантов и нестероидных противовоспалительных препаратов, а также сопутствующие заболевания, такие как диабет, гипертония и сердечно-сосудистые осложнения, могут являться основными причинами поражения почек у пациентов с ревматическими заболеваниями. Кроме того, первичные заболевания почек с длительным анамнезом могут привести к проявлениям, имитирующим первичные ревматологические расстройства. В этом обзоре мы фокусируемся на диагностике нарушений функции почек вследствие основного заболевания, побочных эффектах препаратов и принятии решений о своевременном соответствующем лечении.

Intraoperative blood pressure lability carries a higher risk of headache after carotid endarterectomy

ObjectiveCerebral hyperperfusion syndrome (CHS) is a rare but potentially devastating complication after carotid endarterectomies (CEA). Its symptoms range from new-onset unilateral headache (HA) to intracranial hemorrhage (ICH). Risk factors for CHS in the literature to date have not yet yielded a consensus. This study examines intraoperative and postoperative blood pressure variations as potential risk factors for HA. MethodsA single-center retrospective review at a tertiary care center from January 2010 to November 2019 was performed. Inclusion criteria were all patients undergoing CEA for symptomatic or asymptomatic carotid disease. Patients with incomplete charts were excluded. Primary endpoints were new-onset unilateral HA or postoperative ICH. Data on intraoperative and postoperative mean arterial pressure (MAP), systolic blood pressure (SBP), the mode of endarterectomy, shunt placement, and contralateral carotid status were collected. ResultsThere were 735 patients who met the inclusion criteria: 430 patients underwent modified eversion CEA (59%) and 305 patients for patch angioplasty (42%). The incidence of HA was 19% (n = 142) in our total cohort. Of the 19% with HA, 1.5% (n = 11) demonstrated no relief with analgesics and strict blood pressure control; noncontrast head computed tomography scans were performed subsequently. One patient (0.1%) had an ipsilateral ICH. Univariate analysis demonstrated that greater intraoperative MAP peak had the highest risk for HA (odds ratio [OR], 1.014; 95% confidence interval [CI], 1.007-1.022; P = .0002), followed by intraoperative MAP variability (OR, 1.011; 95% CI,1.005-1.018; P ≤ .0008), and peak intraoperative SBP (OR, 1.01; 95% CI, 1.004-1.015; P = .0011). An unpaired Student t test identified change in intraoperative MAP (P < .005), change in the SBP (P < .005), and peak SBP (P < .001) were significantly associated with HA. Interestingly, there was no significant difference between postoperative MAP variability and HA (P = .1). The mode of endarterectomy showed no statistically significant difference in risk for developing HA (OR, 1.165; 95%; 95% CI, 0.801-1.694; P = .42). ConclusionsGreater intraoperative variability in blood pressures are significantly associated with a higher risk of HA. Adhering to stricter intraoperative blood pressure parameters and limiting blood pressure variability may be beneficial at decreasing the incidence of CHS and its complications.

Medication adherence and blood pressure control among hypertensive patients in Salyan Hospital

Introduction: Hypertension is a chronic medical condition with severe consequences and it remains inadequately managed everywhere. Medication adherence is a critical parameter for achieving strict blood pressure control in patients undergoing antihypertensive therapy. Good medication adherence is also a key factor determining the success of preventive measures for cardiovascular risk reduction. So, we aimed to study the medication adherence and blood pressure control among hypertensive patients of Salyan Hospital.&#x0D; Method: A cross-sectional observational study was conducted in Salyan Hospital. Total of 110 adult hypertensive patients were enrolled in the study. A structured questionnaire i.e. Morisky medication adherence questionnaire (MMAS-8) in Nepali version was used to measure adherence. In addition, WHO validated method of measuring BP, drug type used and type of therapy were also included. Data were entered and analyzed using IBM SPSS.&#x0D; Result: Out of 110 respondents enrolled, less than half of the respondents 45.45% had controlled BP. More than 4/5thwere on monotherapy. BP control in monotherapy was 47.87% and in combination therapy was 45.45%. Patient with high, medium and low adherence were 40.9%, (44.54%) and 14.54% respectively. Level of adherence to antihypertensive drugs was related to BP control (p=0.0004). Most commonly used anti hypertensives were CCBs.&#x0D; Conclusion: There was high prevalence of uncontrolled BP among hypertensive patients in Salyan Hospital. Similarly higher number of patients were on monotherapy. But BP control in monotherapy and combination therapy was similar. Higher number of patients were non-adherent. The relation between BP control and medication adherence was statistically significant. So the causes of poor BP control and poor adherence should be explored and addressed in each doctor-patient encounter.&#x0D; Keywords: Blood Pressure, Medication adherence, Morisky medication adherence questionnaire (MMAS-8)

Prolonged/delayed cerebral hyperperfusion in adult patients with moyamoya disease with RNF213 gene polymorphism c.14576G>A (rs112735431) after superficial temporal artery-middle cerebral artery anastomosis.

Superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis is the standard surgical management for moyamoya disease (MMD), whereas cerebral hyperperfusion (CHP) is one of the potential complications of this procedure that can result in delayed intracerebral hemorrhage and/or neurological deterioration. Recent advances in perioperative management in the early postoperative period have significantly reduced the risk of CHP syndrome, but delayed intracerebral hemorrhage and prolonged/delayed CHP are still major clinical issues. The clinical implication of RNF213 gene polymorphism c.14576G>A (rs112735431), a susceptibility variant for MMD, includes early disease onset and a more severe form of MMD, but its significance in perioperative pathology is unknown. Thus, the authors investigated the role of RNF213 polymorphism in perioperative hemodynamics after STA-MCA anastomosis for MMD. Among 96 consecutive adult patients with MMD comprising 105 hemispheres who underwent serial quantitative cerebral blood flow (CBF) analysis by N-isopropyl-p-[123I]iodoamphetamine SPECT after STA-MCA anastomosis, 66 patients consented to genetic analysis of RNF213. Patients were routinely maintained under strict blood pressure control during and after surgery. The local CBF values were quantified at the vascular territory supplied by the bypass on postoperative days (PODs) 1 and 7. The authors defined the radiological CHP phenomenon as a local CBF increase of more than 150% compared with the preoperative values, and then they investigated the correlation between RNF213 polymorphism and the development of CHP. CHP at POD 1 was observed in 23 hemispheres (23/73 hemispheres [31.5%]), and its incidence was not statistically different between groups (15/41 [36.6%] in RNF213-mutant group vs 8/32 [25.0%] in RNF213-wild type (WT) group; p = 0.321). CHP on POD 7, which is a relatively late period of the CHP phenomenon in MMD, was evident in 9 patients (9/73 hemispheres [12.3%]) after STA-MCA anastomosis. This prolonged/delayed CHP was exclusively observed in the RNF213-mutant group (9/41 [22.0%] in the RNF213-mutant group vs 0/32 [0.0%] in the RNF213-WT group; p = 0.004). Multivariate analysis revealed that RNF213 polymorphism was significantly associated with CBF increase on POD 7 (OR 5.47, 95% CI 1.06-28.35; p = 0.043). Prolonged/delayed CHP after revascularization surgery was exclusively found in the RNF213-mutant group. Although the exact mechanism underlying the contribution of RNF213 polymorphism to the prolonged/delayed CBF increase in patients with MMD is unclear, the current study suggests that genetic analysis of RNF213 is useful for predicting the perioperative pathology of patients with MMD.
