Preliminary Study on Application of Combined Monitoring of Neuroelectrophysiology-Intracranial Pressure-Cerebral Perfusion Pressure in Craniotomy for Intracranial Aneurysm Clipping: An Anatomical and Clinical Study

SUMMARY: Intracranial aneurysm is a common cerebrovascular disease with high mortality. Neurosurgical clipping for the treatment of intracranial aneurysms can easily lead to serious postoperative complications. Studies have shown that intraoperative monitoring of the degree of cerebral ischemia is extremely important to ensure the safety of operation and improve the prognosis of patients. Aim of this study was to probe the application value of combined monitoring of intraoperative neurophysiological monitoring (IONM)-intracranial pressure (ICP)-cerebral perfusion pressure (CPP) in craniotomy clipping of intracranial aneurysms. From January 2020 to December 2022, 126 patients in our hospital with intracranial aneurysms who underwent neurosurgical clipping were randomly divided into two groups. One group received IONM monitoring during neurosurgical clipping (control group, n=63), and the other group received IONM-ICP-CPP monitoring during neurosurgical clipping (monitoring group, n=63). The aneurysm clipping and new neurological deficits at 1 day after operation were compared between the two groups. Glasgow coma scale (GCS) score and national institutes of health stroke scale (NIHSS) score were compared before operation, at 1 day and 3 months after operation. Glasgow outcome scale (GOS) and modified Rankin scale (mRS) were compared at 3 months after operation. All aneurysms were clipped completely. Rate of new neurological deficit at 1 day after operation in monitoring group was 3.17 % (2/63), which was markedly lower than that in control group of 11.11 % (7/30) (P0.05). Combined monitoring of IONM-ICP-CPP can monitor the cerebral blood flow of patients in real time during neurosurgical clipping, according to the monitoring results, timely intervention measures can improve the consciousness state of patients in early postoperative period and reduce the occurrence of early postoperative neurological deficits.

El aneurisma intracraneal es una enfermedad cerebrovascular común con alta mortalidad. El clipaje neuroquirúrgico para el tratamiento de aneurismas intracraneales puede provocar complicaciones posoperatorias graves. Los estudios han demostrado que la monitorización intraoperatoria del grado de isquemia cerebral es extremadamente importante para garantizar la seguridad de la operación y mejorar el pronóstico de los pacientes. El objetivo de este estudio fue probar el valor de la aplicación de la monitorización combinada de la monitorización neurofisiológica intraoperatoria (IONM), la presión intracraneal (PIC) y la presión de perfusión cerebral (CPP) en el clipaje de craneotomía de aneurismas intracraneales. Desde enero de 2020 hasta diciembre de 2022, 126 pacientes de nuestro hospital con aneurismas intracraneales que se sometieron a clipaje neuroquirúrgico se dividieron aleatoriamente en dos grupos. Un grupo recibió monitorización IONM durante el clipaje neuroquirúrgico (grupo de control, n=63) y el otro grupo recibió monitorización IONM-ICP-CPP durante el clipaje neuroquirúrgico (grupo de monitorización, n=63). Se compararon entre los dos grupos el recorte del aneurisma y los nuevos déficits neurológicos un día después de la operación. La puntuación de la escala de coma de Glasgow (GCS) y la puntuación de la escala de accidentes cerebrovasculares de los institutos nacionales de salud (NIHSS) se compararon antes de la operación, 1 día y 3 meses después de la operación. La escala de resultados de Glasgow (GOS) y la escala de Rankin modificada (mRS) se compararon 3 meses después de la operación. Todos los aneurismas fueron cortados por completo. La tasa de nuevo déficit neurológico 1 día después de la operación en el grupo de seguimiento fue del 3,17 % (2/63), que fue notablemente inferior a la del grupo de control del 11,11 % (7/30) (P 0,05). La monitorización combinada de IONM-ICP-CPP puede controlar el flujo sanguíneo cerebral de los pacientes en tiempo real durante el corte neuroquirúrgico; de acuerdo con los resultados de la monitorización, las medidas de intervención oportunas pueden mejorar el estado de conciencia de los pacientes en el período postoperatorio temprano y reducir la aparición de problemas postoperatorios tempranos y déficits neurológicos.

Greater muscle strength is associated with better hemodynamic parameters, physical, cognitive and kidney function in older nursing-home residents / Maior força muscular está associada a melhores parâmetros hemodinâmicos, função física, cognitiva e renal em idosos residentes em casas de repouso

Objective: To analyze hemodynamic parameters, kidney and cognitive function, and physical performance of institutionalized older adults with high- and low-strength. Method: Cross-sectional study. Twenty-one older adults (11 women, 10 men) participated in this study. Blood samples were collected for analysis of biochemical parameters. Cognitive function was evaluated using the mini-mental state examination (MMSE), clock drawing test (CDT), and verbal fluency test, while physical performance was assessed using the Short Physical Performance Battery (SPPB) and, blood pressure, heart rate, and Framingham Risk Score were evaluated. Result: Based on the median value, participants were divided into low-strength (81.63 ± 3.03 years) and high-strength (82.10 ± 2.11 years). The high-strength group showed significantly lower systolic (138.8 ± 3.6 vs. 116.5 ± 3.1; p<0.05), diastolic (84.9 ± 2.14 vs. 72.9 ± 2.2; p<0.05), mean blood pressure (102.2 ± 2.4 vs. 87.4 ± 2.4; p<0.05), and cardiovascular risk (39.7 ± 4.6 vs. 26.0 ± 3.5; p<0.05) than the low-strength group. In addition, the high-strength group had better HDL-c levels (27.4 ± 1.7 vs. 35.6 ± 3.4; p<0.05), higher estimated glomerular filtration rate (51.5 ± 4.9 vs. 86.2 ± 5.5; p<0.05), and lower creatinine (0.94 ± 0.1 vs 0.57 ± 0.1; p<0.05) than the low-strength group. For cognitive data (MMSE and CDT p<0.05) and physical performance (semi-tandem, tandem and walking speed p<0.05), the high-strength group had better scores compared to the low-strength group. Conclusion: Institutionalized older adults with high-strength has better hemodynamic parameters, physical performance, kidney and cognitive function than those with low-strength levels

Association of stage 1 hypertension defined by the 2017 ACC/AHA guideline with cardiovascular events and mortality in Chinese adults / 中华医学杂志(英文版)

BACKGROUND@#The 2017 American College of Cardiology/American Heart Association (ACC/AHA) blood pressure (BP) guideline lowered the threshold defining hypertension to 130/80 mmHg. However, how stage 1 hypertension defined using this guideline is associated with cardiovascular events in Chinese adults remains unclear. This study assessed the association between stage 1 hypertension defined by the 2017 ACC/AHA guideline and clinical outcomes in the Chinese population.@*METHODS@#Participants with stage 1 hypertension ( n = 69,509) or normal BP ( n = 34,142) were followed in this study from 2006/2007 to 2020. Stage 1 hypertension was defined as a systolic blood pressure of 130-139 mmHg or a diastolic blood pressure of 80-89 mmHg. None were taking antihypertensive medication or had a history of myocardial infarction (MI), stroke, or cancer at baseline. The primary outcome was a composite of MI, stroke, and all-cause mortality. The secondary outcomes were individual components of the primary outcome. Cox proportional hazards models were used for the analysis.@*RESULTS@#During a median follow-up of 11.09 years, we observed 10,479 events (MI, n = 995; stroke, n = 3408; all-cause mortality, n = 7094). After multivariable adjustment, the hazard ratios for stage 1 hypertension vs. normal BP were 1.20 (95% confidence interval [CI], 1.13-1.25) for primary outcome, 1.24 (95% CI, 1.05-1.46) for MI, 1.45 (95% CI, 1.33-1.59) for stroke, and 1.11 (95% CI, 1.04-1.17) for all-cause mortality. The hazard ratios for participants with stage 1 hypertension who were prescribed antihypertensive medications compared with those without antihypertensive treatment during the follow-up was 0.90 (95% CI, 0.85-0.96).@*CONCLUSIONS@#Using the new definition, Chinese adults with untreated stage 1 hypertension are at higher risk for MI, stroke, and all-cause mortality. This finding may help to validate the new BP classification system in China.

Relationship of triglyceride-glucose index and its derivatives with blood pressure abnormalities in adolescents: an analysis based on a restricted cubic spline model / 中国当代儿科杂志

OBJECTIVES@#To explore the relationship of triglyceride-glucose index (TyG), triglyceride-glucose-body mass index (TyG-BMI), and triglyceride-glucose-waist circumference index (TyG-WC) with blood pressure abnormalities in adolescents, providing theoretical basis for the prevention and control of hypertension in adolescents.@*METHODS@#A stratified cluster sampling method was used to select 1 572 adolescents aged 12 to 18 years in Yinchuan City for questionnaire surveys, physical measurements, and laboratory tests. Logistic regression analysis and restricted cubic spline analysis were employed to examine the relationship of TyG, TyG-BMI, and TyG-WC with blood pressure abnormalities in adolescents.@*RESULTS@#Multivariable logistic regression analysis revealed that after adjusting for confounding factors, the groups with the highest quartile of TyG, TyG-BMI, and TyG-WC had 1.48 times (95%CI: 1.07-2.04), 3.71 times (95%CI: 2.67-5.15), and 4.07 times (95%CI: 2.89-5.73) higher risks of blood pressure abnormalities compared to the groups with the lowest quartile, respectively. Moreover, as the levels of TyG, TyG-BMI, and TyG-WC increased, the risk of blood pressure abnormalities gradually increased (P<0.05). A non-linear dose-response relationship was observed between TyG-BMI and the risk of blood pressure abnormalities (P overall trend<0.001, P non-linearity=0.002). Linear dose-response relationships were found between TyG and the risk of blood pressure abnormalities (P overall trend<0.001, P non-linearit =0.232), and between TyG-WC and the risk of blood pressure abnormalities (P overall trend<0.001, P non-linearity=0.224).@*CONCLUSIONS@#Higher levels of TyG and its derivatives are associated with an increased risk of blood pressure abnormalities in adolescents, with linear or non-linear dose-response relationships.

Associations of blood pressure change with change in foods' intake among adults with mild to moderate hypertension / 中华心血管病杂志

Objective: To explore the association between the intake and changes in various types of food and the changes in blood pressure in patients with mild to moderate hypertension. Methods: Mild to moderate hypertension participants with complete baseline and outcome data were included from DECIDE-Diet study, a multicenter, randomized controlled trial. Dietary records and blood pressure measurements at both 7-day run-in (baseline) and 28-day intervention phases were collected for enrolled participants. Blood pressure change was defined as the difference between blood pressure at the end of trial and the baseline blood pressure. Baseline intake of food was the average daily intake during the run-in period, and the intake increment was defined as the difference between the average intake during the trial period and the average intake during the run-in period. After adjusting for age, sex, study center, intervention groups, baseline body mass index (kg/m2), antihypertension medication use, and baseline total calorie intake, a linear regression model was used to analyze the associations of the before-after-intervention change in blood pressure with baseline intake and intake increment of foods. Results: A total of 258 patients with mild to moderate hypertension were included, including 133 males, aged (56.5±9.9) years. (1) After adjusting for confounding factors, there was no significant association between baseline intake of food and baseline blood pressure (all P>0.05). The blood pressure change was negatively associated with baseline intakes of tubers, vegetables, and vegetable oils but positively with baseline intake of meats; and was negatively associated with intake increment of whole grains and fish (all P<0.05). (2) The multiple linear regression analysis showed that baseline intake of vegetables (β=-0.021, P=0.004), vegetable oils (β=-0.260, P=0.002), and increment in intake of fish (β=-0.128, P=0.026) were all significantly associated with changes in systolic blood pressure; baseline intake of vegetables (β=-0.017, P=0.002), vegetable oils (β=-0.182, P=0.001), dairy products (β=0.021, P=0.022), and increment in intake of fish (β=-0.092, P=0.010) were all significantly associated with changes in diastolic blood pressure. Conclusion: Increasing the intake of whole grains, vegetables, vegetable oils, and fish and decreasing the intake of meat may be beneficial for blood pressure control in patients with mild to moderate hypertension.

Clinical presentation and outcomes of COVID-19 patients supplemented with approved herbal preparations in Tanzania: A pohort study

Introduction: During the COVID-19 pandemic, there was no known specific treatment for coronavirus Disease. Because of this, different countries and institutions have used different regimens to manage disease symptoms. In Tanzania, well-known and long-used herbal preparations believed to have antiviral activities were used as supplements to standard care for COVID-19 management. This study assessed the clinical presentation and outcomes of hospitalized COVID-19 patients receiving standard care plus herbal preparations in Tanzania. Methods: An observational cohort study was conducted between February and May 2021 at 12 health facilities. Sociodemographic information, clinical presentation, past medical history, baseline, and follow-up laboratory records were documented. Each study participant was followed up for 14 days from enrolment. Results: 285 participants were enrolled; their mean age was 59.2 ± 16.5 years, and males constituted 56% of the study participants. Nearly 33% were aged 50 years and above. The majority (72%) reported having at least one form of co-morbidities (raised blood pressure, diabetes mellitus, asthma, Chronic Obstructive Pulmonary Diseases (COPD) and other forms of heart problems apart from hypertension). More than 60% of the study participants reported to have used at least one form of locally available herbal preparations. Symptoms and signs reported at enrolment subsided relatively faster among those supplemented with herbal preparations than among their counterparts. PCR results of nearly 66% of the study participants had converted to PCR negative at different rates by day 7 (61 vs 78%) and by day 14 (64.3% vs 36.4%) among herbal and non-herbal users, respectively. Overall, proportionally mortality was higher among those who used standard care alone (23.3% vs 16.9%) compared to those supplemented with herbal preparations. Conclusion: The use of herbal preparations in addition to standard care treatment showed a positive effect in subsiding signs and symptoms and decreasing mortality among COVID-19 patients. The findings from this study call for further research, especially clinical trials, to ascertain these findings.

Cambios metabólicos y de aptitud cardiorrespiratoria en mujeres intervenidas con un programa de ejercicio físico asistido con una aplicación móvil: un estudio controlado no randomizado / Metabolic and cardiorespiratory fitness changes in women undergoing a physical exercise program assisted by a mobile application. A non-randomized controlled study

El síndrome metabólico (SMet) es prevalente en nuestra población. El propósito de este estudio es evaluar el efecto del ejercicio físico, asistido con una aplicación móvil (m-Health), sobre la aptitud-cardiorrespiratoria (ACR) e indicadores de riesgo cardiovascular en mujeres con alteraciones metabólicas propias del SMet, y compararlo con el efecto de ejercicio monitoreado de forma presencial en mujeres de similares características. MATERIALES Y MÉTODOS: Estudio controlado no-randomizado con dos brazos. Se reclutaron 41 mujeres con alteraciones metabólicas, 14 completaron el estudio y conformaron por conveniencia el grupo de intervención con m-Health o el control con el Programa Vida Sana, ejecutados durante 10 semanas. Se evaluó la ACR, composición corporal, antropometría, presión arterial (PA); pre y post-intervención. RESULTADOS: El 95% de las mujeres presentaron baja y muy baja ACR basal. El grupo intervenido con m-Health luego de 10 semanas, aumentó el VO2max (% cambio: + 44,4; p = 0,035) y disminuyó el perímetro de cintura (% cam- bio:-2,6; p = 0,022) y la PAD (% cambio:-14,1; p = 0,036). En tanto, el grupo control disminuyó el perímetro de cintura (% cambio:-6,5; p = 0.015) y la PAD (% cambio:-12,2; p = 0,05), pero no modificó el VO2max. Las comparaciones entre grupos no arrojaron diferencias. CONCLUSIONES: Un programa de ejercicio físico vía m-Health mejoró la ACR y parámetros antropométricos en mujeres con alteraciones cardiometabólicas.

Metabolic syndrome (MetS) is prevalent in our population. The purpose of this study is to evaluate the effect of physical exercise, assisted by a mobile application (m-Health), on cardiorespiratory fitness (ACR) and cardiovascular risk markers in women with metabolic disorders typical of MetS, and to compare it with the effect of exercise monitored face to face in women with similar characteristics. MATERIALS AND METHODS: Controlled experimental study with two arms. Forty-one women with metabolic disorders were recruited; 14 completed the study and, for convenience, formed the intervention group with m-Health or the control group with the Vida Sana Program, both carried out for ten weeks. ACR, body composition, anthropometry, and blood pressure (BP) were evaluated before and after the intervention. RESULTS: 95% of the women presented low and very low basal ACR. The group treated with m-Health after 10 weeks increased VO2max (% change: + 44.4; p = 0.035) and decreased waist circumference (% change: -2.6; p = 0.022) and DBP (% change: -14.1; p = 0.036). Meanwhile, the control group decreased waist circumference (% change: -6.5; p = 0.015) and DBP (% change: -12.2; p = 0.05) but did not change VO2 max. Comparisons between groups did not show differences. Conclusions: A physical exercise program via m-Health improved ACR and anthropometric parameters in women with cardiometabolic disorders.

Association between blood pressure during 12-28 weeks gestation and pre-eclampsia: predictive value of blood pressure trajectories constructed by latent class growth modeling / 中华心血管病杂志

Objective: To explore the associations between blood pressure trajectories during pregnancy and risk of future pre-eclampsia in a large cohort enrolling pregnant women at gestational age of ~12 weeks from community hospitals in Tianjin. Latent class growth modeling (LCGM) was used to model the blood pressure trajectories. Methods: This was a large prospective cohort study. The study enrolled pregnant women of ~12 weeks of gestation in 19 community hospitals in Tianjin from November 1, 2016 to May 30, 2018. We obtained related information during 5 antepartum examinations before gestational week 28, i.e., week 12, week 16, week 20, week 24 and week 28. LCGM was used to model longitudinal systolic (SBP) and diastolic blood pressure (DBP) trajectories. For the association study, the predictors were set as SBP and DBP trajectory membership (built separately), the outcome was defined as the occurrence of preeclampsia after 28 weeks of gestation. Results: A total of 5 809 cases with known pregnant outcomes were documented. After excluding 249 cases per exclusion criteria, 5 560 cases with singleton pregnancy were included for final analysis. There were 128 cases preeclampsia and 106 cases gestational hypertension in this cohort. Univariate logistic regression and multivariate logistic regression showed the higher baseline SBP level and DBP level were related with increased risk of preeclampsia. Four distinctive SBP trajectories and DBP trajectories from 12 weeks to 28 weeks of gestation were identified by LCGM. After controlling for potential confounders (baseline BMI, being primipara or not, white blood cell counts, hemoglobin level, platelet counts and alanine aminotransferase level), the OR for SBP latent classification trajectory_ 4 was 4.023 (95%CI: 2.368 to 6.835, P<0.001), and the OR for SBP latent classification trajectory_3 was 1.854 (95%CI: 1.223 to 2.811, P=0.004). Logistic regression showed that: using the DBP latent classification trajectory_1 as the reference group, the OR for DBP latent classification trajectory_4 was 4.100 (95%CI: 2.571 to 6.538, P<0.001), and 2.632 (95%CI: 1.570 to 4.414, P<0.001) for DBP latent classification trajectory_2. After controlling for potential confounders (baseline BMI, being primipara or not, white blood cell counts, hemoglobin level, platelet counts and alanine aminotransferase level), the OR for DBP_traj_4 was 2.527 (95%CI: 1.534 to 4.162, P<0.001), and the OR for DBP_traj_3 was 1.297 (95%CI: 0.790 to 2.128, P=0.303), and 2.238 (95%CI: 1.328 to 3.772, P=0.002) for DBP_traj_2. Therefore, BP trajectories from 12 weeks to 28 weeks identified by LCGM served as novel risk factors that independently associated with the occurrence of preeclampsia. Receiver operating characteristic (ROC) curve analysis showed incremental diagnostic performance by combing baseline blood pressure levels with blood pressure trajectories. Conclusion: By applying LCGM, we for the first time identified distinctive BP trajectories from gestational week 12 to 28, which can independently predict the development of preeclampsia after 28 weeks of gestation.

Impact of individual and combined assessment of age- and sex-specific brachial-ankle pulse wave velocity and pulse pressure on all-cause mortality / 中华心血管病杂志

Objective: To evaluate the impact of individual and combined assessment of age- and sex-specific brachial-ankle pulse wave velocity (baPWV) and pulse pressure (PP) on all-cause mortality. Methods: This study is a prospective cohort study. Individuals participated in the Kailuan Study and completed baPWV measurements between 2010 and 2016 were included in this study. After stratifying by sex, 75th percentile baPWV and PP values for different age group were calculated at five years interval. BaPWV and PP values below the 75th percentile were defined as normal, and those above or equal to the 75th percentile were defined as increased. The participants were allocated to four groups according to their PP and baPWV status: normal baPWV/PP group, high baPWV/normal PP group, normal baPWV/high PP group and high baPWV/PP group. The primary outcome was all-cause mortality during the follow-up period. Cox proportional hazards models were used to explore the impact of individual and combined assessment of baPWV and PP on all-cause mortality events. Results: A total of 39 339 participants were enrolled in this study, aged (49.3±12.8) years, of which 28 731 (73.03%) were males. There were 23 268, 6 025, 6 210 and 3 836 cases in the normal baPWV/PP group, high baPWV/normal PP group, normal baPWV/high PP group and high baPWV/PP group, respectively. The average follow-up duration was (4.98±2.53) years. During the follow-up period, all-cause mortality occurred in 998 individuals. Multivariate Cox regression analysis showed increased risk of all-cause mortality in the high baPWV/normal PP group (HR=1.27, 95%CI 1.07-1.50), and in the high baPWV/PP group (HR=1.33, 95%CI 1.08-1.65) compared to the normal baPWV/PP group. Increased pulse pressure alone had no impcat on all-cause death (HR=1.06, 95%CI 0.87-1.29). Conclusions: The risk of all-cause mortality significantly increases with increased age-and sex-specific baPWV and PP values. BaPWV may be a better predictor of all-cause mortality than PP in this cohort.

Effect of out-hospital blood pressure management on prognosis of patients with acute aortic syndrome complicated with hypertension after TEVAR / 中华心血管病杂志

Objective: To investigate the influence of blood pressure control after discharge on prognosis of patients with acute aortic syndrome (AAS) complicated with hypertension who underwent thoracic endovascular aortic repair (TEVAR). Methods: This is a retrospective case analysis. Patients diagnosed with AAS complicated with hypertension and undergoing TEVAR in Northern Theater Command General Hospital from June 2002 to December 2021 were consecutively enrolled. Average systolic blood pressure (SBP) and the occurrence of endpoint events were recorded at one month, one year and every 2 years after TEVAR. According to the patients' average SBP, patients with average SBP<140 mmHg (1 mmHg=0.133 kPa) or<150 mmHg were divided into the target blood pressure achievement group, and the others were divided into target blood pressure non-achievement group. Endpoint events included all-cause death, aortic death, stroke, renal insufficiency, aortic related adverse events and a composite of these events (overall clinical adverse events), and re-accepting TEVAR. The incidence of endpoint events was compared between the two groups at each follow-up period. Results: A total of 987 patients were included, aged (55.7±11.7) years, including 779 male (78.9%). When the cutoff value was 140 mmHg, the rate of average target SBP achievement was 71.2% (703/987) at one month, 66.7% (618/927) during 1st to 12th month and 65.1% (542/832) from the first year to the third year after TEVAR. The proportion of patients taking≥2 antihypertensive agents was higher in the group of target blood pressure non-achievement group than the target blood pressure achievement group after TEVAR at 1 month (74.3% (211/284) vs.65.9% (463/703), P=0.010) and during 1st to 12th month (71.5% (221/309) vs. 63.6% (393/618), P=0.016). There were no statistical differences in the all-cause deaths, stroke, aortic related adverse events, and repeat TEVAR between the two groups (All P>0.05) during above follow-up periods. When the cutoff value was 150 mmHg, the rate of target SBP achievement was 89.3% (881/987) at one month, 85.2% (790/927) during 1st to 12th month and 85.6%(712/832) from the first year to the third year after TEVAR. The incidence of clinical total adverse events (8.8% (12/137) vs. 4.2% (33/790), P=0.021) and repeat TEVAR (4.4% (6/137) vs. 1.0% (8/790), P=0.003) in target blood pressure non-achievement group were significantly higher than the target blood pressure achievement group during 1st to 12th month after TEVAR. The incidence of all-cause deaths (5.8% (7/120) vs. 2.4% (17/712), P=0.037) in the target blood pressure non-achievement group was significantly higher than the target blood pressure achievement group from the first year to the third year follow-up period, but there were no statistical differences in the incidence of clinical total adverse events between the two group (P>0.05). Conclusion: Among TEVAR treated AAS patients complicated with hypertension, the average SBP more than 150 mmHg post discharge is associated with increased risk of adverse events. Ideal blood pressure control should be encouraged to improve the outcome of these patients.

Sulfur dioxide in the caudal ventrolateral medulla reduces blood pressure and heart rate in rats via the glutamate receptor and NOS/cGMP signal pathways / 生理学报

This study was designed to investigate the cardiovascular effects of sulfur dioxide (SO2) in the caudal ventrolateral medulla (CVLM) of anesthetized rats and its mechanism. Different doses of SO2 (2, 20, 200 pmol) or artificial cerebrospinal fluid (aCSF) were injected into the CVLM unilaterally or bilaterally, and the effects of SO2 on blood pressure and heart rate of rats were observed. In order to explore the possible mechanisms of SO2 in the CVLM, different signal pathway blockers were injected into the CVLM before the treatment with SO2 (20 pmol). The results showed that unilateral or bilateral microinjection of SO2 reduced blood pressure and heart rate in a dose-dependent manner (P < 0.01). Moreover, compared with unilateral injection of SO2 (2 pmol), bilateral injection of 2 pmol SO2 produced a greater reduction in blood pressure. Local pre-injection of the glutamate receptor blocker kynurenic acid (Kyn, 5 nmol) or soluble guanylate cyclase (sGC) inhibitor 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ, 1 pmol) into the CVLM attenuated the inhibitory effects of SO2 on both blood pressure and heart rate. However, local pre-injection of nitric oxide synthase (NOS) inhibitor NG-Nitro-L-arginine methyl ester (L-NAME, 10 nmol) only attenuated the inhibitory effect of SO2 on heart rate but not blood pressure. In conclusion, SO2 in rat CVLM has cardiovascular inhibitory effects, and its mechanism is related to the glutamate receptor and NOS/cGMP signal pathways.

Ambient Fine Particulate Matter Exposure and Blood Pressure: Evidence from a Large Chinese Multiple Follow-Up Study / 生物医学与环境科学（英文）

OBJECTIVE@#This study aimed to investigate the association of ambient PM2.5 exposure with blood pressure (BP) at the population level in China.@*METHODS@#A total of 14,080 participants who had at least two valid blood pressure records were selected from the China Health and Retirement Longitudinal Survey during 2011-2015. Their long-term PM2.5 exposure was assessed at the geographical level, on the basis of a regular 0.1° × 0.1° grid over China. A mixed-effects regression model was used to assess associations.@*RESULTS@#Each decrease of 10 μg/m3 in the 1 year-mean PM2.5 concentration (FPM1Y) was associated with a decrease of 1.24 [95% confidence interval (CI): 0.84-1.64] mmHg systolic BP (SBP) and 0.50 (95% CI: 0.25-0.75) mmHg diastolic BP (DBP), respectively. A robust association was observed between the long-term decrease in PM2.5 and decreased BP in the middle-aged and older population. Using a generalized additive mixed model, we further found that SBP increased nonlinearly overall with FPM1Y but in an approximately linear range when the FPM1Y concentration was < 70 µg/m3; In contrast, DBP increased approximately linearly without a clear threshold.@*CONCLUSION@#Efficient control of PM2.5 air pollution may promote vascular health in China. Our study provides robust scientific support for making the related air pollution control policies.

Guidelines for hypertension management in patients with chronic kidney disease in China (2023) / 中华肝脏病杂志

The population of chronic kidney disease (CKD) with hypertension in China is characterized by complex etiology, high incidence rate, low awareness and control rate. How to diagnose and treat hypertension in CKD patients properly and improve their prognosis is particularly urgent. Several clinical guidelines or expert consensus on the diagnosis, treatment and management of hypertension have been issued. Some of them involve the diagnosis and treatment of hypertension in CKD patients, but they still can not meet the demand for diagnosis and treatment of hypertension in CKD patients. Based on the situation of hypertension in CKD patients in China, the Chinese Society of Nephrology organized an expert group to formulate this guideline. This guideline systematically introduces the diagnostic criteria, epidemiology, risk factors, poor prognosis of hypertension, the purpose, timing and control goals of antihypertensive therapy in CKD patients, as well as blood pressure control goals for special populations, non drug treatment and drug treatment of hypertension. This guideline aims to further strengthen the management of hypertension in CKD patients, standardize the diagnosis and treatment standards, formulate reasonable treatment plans, effectively control hypertension, reduce complications, so as to delay the progress of kidney diseases and improve the long-term prognosis of hypertension in Chinese CKD patients.

Inducible co-stimulatory molecules participate in mesenteric vascular endothelial-mesenchymal transition and sclerosis of mesenteric vessels in spontaneously hypertensive rats / 南方医科大学学报

OBJECTIVE@#To investigate the correlation of inducible co-stimulatory molecules (ICOS) with mesenteric vascular endothelial- mesenchymal transition (EndMT) and sclerosis in spontaneously hypertensive rats (SHR).@*METHODS@#Twenty 4-week-old WKY rats and 20 SHRs of the same strain were both randomly divided into 4 groups for observation at 4, 6, 10 and 30 weeks of age. ICOS expression frequency in rat spleen CD4+T cells was analyzed using flow cytometry, and the expressions of ICOS, VE-cad, α-SMA and Col3 mRNA in rat mesentery were detected by RT-PCR. The distributions of ICOS, IL-17A and TGF-β in rat mesentery were detected by immunohistochemistry. The levels of IL-17A and TGF-β in rat plasma were measured using ELISA. The morphological changes of rat mesenteric vessels were observed with Masson staining. Spearman or Pearson correlation analyses were used to evaluate the correlation between ICOS expression and the expressions of the markers of vascular EndMT and sclerosis.@*RESULTS@#Compared with the control WKY rats, the SHRs began to show significantly increased systolic blood pressure and ICOS expression frequency on CD4+T cells at 6 weeks of age (P < 0.05). In the SHRs, the mRNA and protein expressions of ICOS, α-SMA, Col3, IL-17A and TGF-β in the mesentery were significantly higher than those in control group (P < 0.05), while the mRNA and protein expressions of VE-cad started to reduce significantly at 10 weeks of age (P < 0.05). The plasma levels of IL-17A and TGF-β were significantly increased in SHRs since 6 weeks of age (P < 0.05) with progressive worsening of mesenteric vascular sclerosis (P < 0.05). ICOS mRNA and protein expression levels in the mesenteric tissues of SHRs began to show positive correlations with α-SMA and Col3 expression levels and the severity of vascular sclerosis at 6 weeks of age (P < 0.05) and a negative correlation with VE-cad expression level at 10 weeks (P < 0.05).@*CONCLUSION@#ICOS play an important pathogenic role in EndMT and sclerosis of mesenteric vessels in essential hypertension by mediating related immune responses.

With big data technology, wearable data can be analyzed to help long-term cardiovascular care. This review summarizes the recent developments of wearable technology related to cardiovascular care, highlighting the most common wearable devices and their accuracy. We also examined the application of these devices in cardiovascular healthcare, such as the early detection of arrhythmias, measuring blood pressure, and detecting prevalent diabetes. We provide an overview of the challenges that hinder the widespread application of wearable devices, such as inadequate device accuracy, data redundancy, concerns associated with data security, and lack of meaningful criteria, and offer potential solutions. Finally, the future research direction for cardiovascular care using wearable devices is discussed.

Low diastolic blood pressure and adverse outcomes in inpatients with acute exacerbation of chronic obstructive pulmonary disease: A multicenter cohort study / 中华医学杂志(英文版)

BACKGROUND@#Although intensively studied in patients with cardiovascular diseases (CVDs), the prognostic value of diastolic blood pressure (DBP) has little been elucidated in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). This study aimed to reveal the prognostic value of DBP in AECOPD patients.@*METHODS@#Inpatients with AECOPD were prospectively enrolled from 10 medical centers in China between September 2017 and July 2021. DBP was measured on admission. The primary outcome was all-cause in-hospital mortality; invasive mechanical ventilation and intensive care unit (ICU) admission were secondary outcomes. Least absolute shrinkage and selection operator (LASSO) and multivariable Cox regressions were used to identify independent prognostic factors and calculate the hazard ratio (HR) and 95% confidence interval (CI) for adverse outcomes.@*RESULTS@#Among 13,633 included patients with AECOPD, 197 (1.45%) died during their hospital stay. Multivariable Cox regression analysis showed that low DBP on admission (<70 mmHg) was associated with increased risk of in-hospital mortality (HR = 2.16, 95% CI: 1.53-3.05, Z = 4.37, P <0.01), invasive mechanical ventilation (HR = 1.65, 95% CI: 1.32-2.05, Z = 19.67, P <0.01), and ICU admission (HR = 1.45, 95% CI: 1.24-1.69, Z = 22.08, P <0.01) in the overall cohort. Similar findings were observed in subgroups with or without CVDs, except for invasive mechanical ventilation in the subgroup with CVDs. When DBP was further categorized in 5-mmHg increments from <50 mmHg to ≥100 mmHg, and 75 to <80 mmHg was taken as reference, HRs for in-hospital mortality increased almost linearly with decreased DBP in the overall cohort and subgroups of patients with CVDs; higher DBP was not associated with the risk of in-hospital mortality.@*CONCLUSION@#Low on-admission DBP, particularly <70 mmHg, was associated with an increased risk of adverse outcomes among inpatients with AECOPD, with or without CVDs, which may serve as a convenient predictor of poor prognosis in these patients.@*CLINICAL TRIAL REGISTRATION@#Chinese Clinical Trail Registry, No. ChiCTR2100044625.

Effect of Home Blood Pressure Telemonitoring Plus Additional Support on Blood Pressure Control: A Randomized Clinical Trial / 生物医学与环境科学（英文）

OBJECTIVE@#Current clinical evidence on the effects of home blood pressure telemonitoring (HBPT) on improving blood pressure control comes entirely from developed countries. Thus, we performed this randomized controlled trial to evaluate whether HBPT plus support (patient education and clinician remote hypertension management) improves blood pressure control more than usual care (UC) in the Chinese population.@*METHODS@#This single-center, randomized controlled study was conducted in Beijing, China. Patients aged 30-75 years were eligible for enrolment if they had blood pressure [systolic (SBP) ≥ 140 mmHg and/or diastolic (DBP) ≥ 90 mmHg; or SBP ≥ 130 mmHg and/or DBP ≥ 80 mmHg with diabetes]. We recruited 190 patients randomized to either the HBPT or the UC groups for 12 weeks. The primary endpoints were blood pressure reduction and the proportion of patients achieving the target blood pressure.@*RESULTS@#Totally, 172 patients completed the study, the HBPT plus support group ( n = 84), and the UC group ( n = 88). Patients in the plus support group showed a greater reduction in mean ambulatory blood pressure than those in the UC group. The plus support group had a significantly higher proportion of patients who achieved the target blood pressure and maintained a dipper blood pressure pattern at the 12th week of follow-up. Additionally, the patients in the plus support group showed lower blood pressure variability and higher drug adherence than those in the UC group.@*CONCLUSION@#HBPT plus additional support results in greater blood pressure reduction, better blood pressure control, a higher proportion of dipper blood pressure patterns, lower blood pressure variability, and higher drug adherence than UC. The development of telemedicine may be the cornerstone of hypertension management in primary care.
