Relación de la enfermedad periodontal inflamatoria crónica con enfermedades sistémicas / Relationship of chronic inflammatory periodontal disease with systemic diseases

Introducción: La enfermedad periodontal es una infección inmunoinflamatoria crónica de origen multifactorial. Puede avanzar a nivel sistémico por el paso de bacterias y sus productos al torrente sanguíneo, lo cual constituye un factor de riesgo para alteraciones sistémicas. La revisión bibliográfica se realizó de julio 2022 hasta febrero 2023. Se utilizaron las bases de datos PubMed, SciELO y Elsevier y el motor de búsqueda Google Académico. Objetivos: Describir la relación de la enfermedad periodontal inflamatoria crónica con enfermedades sistémicas. Desarrollo: La medicina periodontal estudia la relación que existe entre las periodontopatías y enfermedades sistémicas, como las cardiovasculares, cerebrovasculares, pulmonares, la renal crónica, la artritis reumatoide y el Alzheimer. Las bacterias provenientes de las bolsas periodontales pasan hacia la circulación sanguínea, producen infección metastásica y daño metastásico, mediante la producción de endotoxinas, lipopolisacáridos e inflamación metastásica. Conclusiones: La enfermedad periodontal crónica constituye un factor de riesgo para el desarrollo de enfermedades cardiovasculares, pulmonares, renales, trastornos cerebrovasculares, artritis reumatoide y el Alzheimer debido a reacciones inflamatorias producidas por microorganismos patogénicos; se establece una relación bidireccional entre estas enfermedades y las periodontopatías(AU)

Introduction: Periodontal disease is a chronic immunoinflammatory infection of multifactorial origin. It can advance at a systemic level due to the passage of bacteria and their products into the bloodstream, which constitutes a risk factor for systemic alterations. The bibliographic review was carried out from July 2022 to February 2023. The PubMed, SciELO and Elsevier databases and the Google Scholar search engine were used. Objectives: Describe the relationship of chronic inflammatory periodontal disease with systemic diseases. Development: Periodontal medicine studies the relationship between periodontopathies and systemic diseases, such as cardiovascular, cerebrovascular, pulmonary, chronic kidney disease, rheumatoid arthritis and Alzheimer's. Bacteria from periodontal pockets pass into the blood circulation, producing metastatic infection and metastatic damage, through the production of endotoxins, lipopolysaccharides and metastatic inflammation. Conclusions: Chronic periodontal disease constitutes a risk factor for the development of cardiovascular, pulmonary, renal diseases, cerebrovascular disorders, rheumatoid arthritis and Alzheimer's due to inflammatory reactions produced by pathogenic microorganisms; A bidirectional relationship is established between these diseases and periodontopathies. The analysis of this relationship and the mechanisms by which it occurs guarantees the development of a more integrative care practice(AU)

Recently, numerous studies have confirmed the close relationship between cardiovascular and cerebrovascular diseases and the gut microbiota as well as gut metabolites. Fel Ursi contains bile acid components that may have bidirectional regulatory effects on the gut microbiota and gut metabolites. This aspect could represent a potential therapeutic pathway for Fel Ursi in the treatment of cardiovascular and cerebrovascular diseases. This article comprehensively summarized relevant literature in China and abroad, reviewed the research progress on the pharmacological effects of Fel Ursi against cardiovascular and cerebrovascular diseases, and explored the impact of Fel Ursi on gut microbiota and gut metabolites, thereby aiming to provide references for further in-depth research and clinical application of Fel Ursi.

Report on cardiovascular and cerebrovascular health and diseases in Hunan Province, 2020 / 中南大学学报(医学版)

Being the leading cause of death among both urban and rural residents in Hunan Province, China, cardiovascular and cerebrovascular diseases hold a significant position in the region's public health landscape. Their prevalence and impact not only underscore the urgency of effective disease prevention and control but also provide crucial guidance for future initiatives. Consequently, the Hunan Province Cardiovascular and Cerebrovascular Health and Disease Report Summary (2020) hereinafter referred to as the "Annual Report", serves as an extensive and informative document. It meticulously examines the current status of these diseases, highlighting both the existing challenges and opportunities for prevention and control efforts in Hunan Province. The primary objective of this report is to furnish valuable insights and evidence that will empower and enrich future endeavors aimed at combatting cardiovascular and cerebrovascular diseases within the region. In 2017, the year of life expectancy lost due to cardiovascular and cerebrovascular diseases in Hunan Province remained higher than the national average. Additionally, the per capita life expectancy in 2019 (77.1 years) was slightly lower by 0.2 years compared with the national average (77.3 years). Alarmingly, the mortality rates associated with cardiovascular and cerebrovascular diseases were consistently ranking highest, indicating an upward trajectory. Moreover, the prevalence and mortality rates of conditions such as hypertension, coronary heart disease, and stroke, all encompassed within the domain of cardiovascular and cerebrovascular diseases, surpassed the national averages. Consequently, the economic burden attributable to cardiovascular and cerebrovascular diseases is on the rise. And under vertical comparison, in 2019, the life expectancy per capita in Hunan Province increased by 1.26 years compared with 2015. The incidence rate of cardiovascular and cerebrovascular events decreased by 8.34% compared with 2017. A new model of hypertension medical and preventive integration has been established with the efforts of many experts in Hunan Province, and full coverage of standardised outpatient clinics for hypertension at the grassroots level has been realised. The rate of standardised management of patients with hypertension under management in Changsha County, a demonstration area, rose to 65.27%, and the incidence rate of cardiovascular and cerebrovascular events, the incidence rate of stroke, and the mortality rate due to cardiovascular and cerebrovascular events were reduced by 28.08%, 28.62%, and 25.00%, respectively. Hunan Province has made significant strides in the prevention and control of cardiovascular and cerebrovascular diseases in recent years.

Network Meta-analysis of single Hirudo prescriptions in treatment of ischemic cerebrovascular disease / 中国中药杂志

This study intended to evaluate the efficacy and safety of single Hirudo prescriptions in the treatment of ischemic cerebrovascular disease(ICVD) by frequency network Meta-analysis and traditional Meta-analysis. CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, and Cochrane Library databases were searched to collect the randomized controlled trial(RCT) of single Hirudo prescriptions for ICVD from the inception of the databases to May 2022. The quality of the included literature was evaluated by Cochrane risk of bias tool. Finally, 54 RCTs and 3 single Hirudo prescriptions were included. Statistical analysis was conducted by RevMan 5.3 and Stata SE 15. Network Meta-analysis showed that in terms of the clinical effective rate, the surface under the cumulative ranking curve(SUCRA) of intervention measures was as follows: Huoxue Tongmai Capsules+conventional treatment>Maixuekang Capsules+conventional treatment>Naoxuekang Capsules+conventional treatment>conventional treatment. Traditional Meta-analysis revealed that in terms of the safety of ICVD treatment, Maixuekang Capsules+conventional treatment had higher safety than conventional treatment alone. According to the network Meta-analysis and traditional Meta-analysis, it was found that conventional treatment combined with single Hirudo prescriptions improved the clinical efficacy of ICVD patients, and compared with that of conventional treatment alone, the incidence of adverse reactions of combined treatment was low and the safety was high. However, the methodological quality of the articles included in this study was generally low and there were large differences in the number of articles on the three combined medication. Therefore, the conclusion of this study needed to be confirmed by subsequent RCT.

Research and application of model fruit fly in prevention and treatment of neuropsychiatric disorders by traditional Chinese medicine and natural compounds: a review / 中国中药杂志

As an important model animal, fruit fly is characterized by outstanding genetic characteristics, relatively perfect nervous system, rapid reproduction, and low cost. Thus, it has been applied in the research on neuropsychiatric disorders in recent years, showing great potential in life science. The incidence of neuropsychiatric disorders has been on the rise, and the disorders have high disability rate and low case fatality rate. The global drug demand for such diseases is second only to cardiovascular and cerebrovascular diseases. At the moment, the demand of the drugs for the diseases have been rising, and it is an urgent task to develop related drugs. However, the research and development of the drugs are time-intensive and have a high failure rate. A suitable animal model can help shorten the time for drug screening and development, thereby reducing the cost and failure rate. This study reviews the application of fruit flies in several common neuropsychiatric disorders, which is expected to provide new ideas for the research and application of the model animals in traditional Chinese medicine.

Intensive care unit deaths among neurosurgery patients in a tertiary hospital in South Western Nigeria

Neurosurgical patients are the most critical ICU admissions. While advancements in neurosurgical ICUs (NICU) have improved outcomes of care globally, ICU mortality remains a major clinical issue in developing nations. This study evaluates ICU mortalities of neurosurgical patients in a general ICU setting at the UNIOSUN Teaching Hospital, Osogbo, Nigeria. Method: Case records of neurosurgery patients who died in the ICU of UNIOSUN Teaching Hospital, Osogbo, South-Western, Nigeria from June 2012 to May 2022 were reviewed. Simple descriptive statistics of data on demographics, clinical diagnoses, management and outcome were done. Results: Mortality rate was 38.9% (84 of 216 admissions). Males were 67(79.8%) and the mean age was 41.5years (Range: 2-85years). The average duration of ICU stay was 3.5days (Range: 30minutes-20days). Most patients had severe traumatic brain injury (TBI) (62, 73.8%). This was followed by cerebrovascular diseases (12, 14.3%) and brain tumours (6, 7.1%). Two had brain abscess. One patient each had mixed subacute/chronic subdural haematoma and severe cervical spondylotic myelopathy. Of the 69 whose case files were found, 7(10.1%) had a diagnosis of brainstem death before eventual 'final' death after an average of 13.5 additional hours on mechanical life support. The identified secondary causes of death included raised ICP, sepsis, primary surgical haemorrhage, seizures, acute kidney injury, malignant hypertension, poor glycaemic control and aggressive blood pressure lowering. Only 1 patient had autopsy. Conclusion: Most ICU mortalities among neurosurgical patients were from severe TBI. The establishment of NICU is necessary to improve outcome of care of neurosurgical patients

Deterioro cognitivo de origen vascular y demencia vascular esporádica: revisión narrativa de tema basada en la evidencia / Cognitive impairment of vascular origin and sporadic vascular dementia: an evidence-based narrative topic review

RESUMEN INTRODUCCIÓN: La enfermedad cerebrovascular y las demencias están unidas por el deterioro cognitivo y la demencia vascular. Se trata de condiciones de salud potencialmente prevenibles, capaces de generar discapacidad, especialmente en la población adulta mayor. METODOLOGÍA: El propósito de este trabajo es caracterizar el deterioro cognitivo vascular y el espectro de la demencia vascular esporádica, mediante una revisión de tema con énfasis neurocognitivo. RESULTADOS: Entre el 30 % y el 40 % de las personas con enfermedad cerebrovascular experimentan algún grado de compromiso cognitivo. Después de los tres meses de haber presentado una enfermedad cerebro-vascular, alrededor del 20 % al 30 % de los pacientes serán diagnosticados con demencia, y entre un 10 % y un 35 %, con deterioro cognitivo. El deterioro cognitivo vascular y la demencia vascular tienen una serie de factores comunes a la enfermedad cerebrovascular y a la enfermedad de Alzheimer. La demencia vascular presenta subtipos: la demencia multiinfarto, caracterizada por varios infartos cerebrales que se acumulan en el tiempo; la demencia por infarto estratégico, en la que hay infartos localizados en zonas cortico-subcorticales con gran conectividad; y la demencia por enfermedad isquémica de pequeñas arterias, producida por infartos lacunares o lesiones difusas de sustancia blanca, que afecta principalmente la velocidad de procesamiento y las funciones ejecutivas. CONCLUSIONES: El deterioro cognitivo en personas con enfermedad cerebrovascular involucra pérdidas en el rendimiento de una o varias funciones mentales superiores, situación que puede evolucionar hasta la demencia, en la que un déficit permanente en las funciones mentales afecta de manera importante el desempeño y el funcionamiento. Sin embargo, es un tema que permite hablar y promover activamente el control o la modificación de factores de riesgo cardiovascular.

ABSTRACT INTRODUCTION: Cerebrovascular disease and dementias are linked by cognitive impairment and dementia of vascular origin. Potentially preventable health conditions capable of generating disability, especially in the older adult population. METHODOLOGY: The purpose is to characterize the cognitive impairment of vascular origin and the spectrum of sporadic vascular dementia, through a review of the topic with a neurocognitive emphasis. RESULTS: Between 30 % to 40 % of people with cerebrovascular disease acquire some degree of cognitive impairment. After three months of having experienced a cerebrovascular disease, about 20 % to 30 % of patients will be diagnosed with dementia and between 10 % and 35 % with cognitive impairment. Vascular cognitive impairment and vascular dementia have several factors common to cerebrovascular disease and Alzheimer's disease. Vascular dementia has subtypes: multi-infarct dementia characterized by several cerebral infarcts that accumulate over time; dementia due to strategic infarction, where there are infarcts located in cortico-subcortical areas with great connectivity; and dementia due to ischemic disease of the small arteries, produced by lacunar infarcts or diffuse lesions of the white matter, which mainly affect processing speed and executive functions. CONCLUSIONS: Cognitive impairment in people with cerebrovascular disease involves losses in the performance of one or several higher mental functions, a situation that can evolve to dementia, where a permanent deficit in mental functions significantly affects performance and functioning. However, it is a topic that allows to speak and actively promote the control and / or modification of cardiovascular risk factors.

Prediction on the cardio-cerebrovascular death and probability of premature death caused by common risk factors in China in 2030 / 中华预防医学杂志

Objective: Predictive models were used to evaluate the impact of common risk factors on the number of cardio-cerebrovascular deaths and the probability of premature death. Methods: Using the data for China estimated by the Global Burden of Disease study 2015 (GBD 2015), we calculated the population attribution fraction (PAF) of risk factors. The proportional change model was used to estimate the number of unattributable deaths by 2030, and to predict the number of deaths, mortality, standardized mortality and probability of premature death by 2030. Results: According to the natural change trend of risk factors from 1990 to 2015, the number of deaths and mortality would reach 6.12 million and 428.53/100 000 by 2030, with an increase of 59.92% and 52.87%. By 2030, the probability of premature death from cardio-cerebrovascular diseases among Chinese aged 30-70 years old would continue to decline, from 11.43% to 11.28% for men, and from 5.79% to 4.43% for women. If the goals of all included risk factors were reached by 2030, 2 289 200 cardio-cerebrovascular deaths would be avoided. If only the exposure to a single risk factor was achieved by 2030, blood pressure, total cholesterol, and fine particulate matter exposure were the three most important factors affecting cardio-cerebrovascular deaths, which would reduce 1 332 800, 609 100 and 306 800 deaths, respectively. Among the involved risk factors, the control of blood pressure would mostly decrease the number of deaths due to ischemic heart disease and hemorrhagic stroke, about 677 300 and 391 100 deaths, accordingly. Conclusion: The control of risk factors is of great significance in reducing deaths and probability of premature death due to cardio-cerebrovascular diseases. If the control targets of all risk factors could be achieved by 2030, the burden of cardio-cerebrovascular diseases would be reduced greatly.

Analysis on mortality and premature death rates of 4 major chronic diseases in Ji'nan, 2015-2020 / 中华流行病学杂志

Objective: To understand the characteristics and trend of the premature death rate of 4 major chronic diseases in Ji'nan from 2015 to 2020. Methods: The death cause surveillance data and population data during 2015-2020 in Ji'nan were collected, and abbreviated life table, Joinpoint regression analysis and other methods were used to analyze the characteristics and change trends of the premature death rates of 4 major chronic diseases. Results: The crude mortality rate and age standardized mortality rate changes for the 4 major chronic diseases from 2015 to 2020 range from 568.65/100 000 to 604.06/100 000 and 366.77/100 000 to 432.48/100 000, respectively. The annual premature death rate of 4 major chronic diseases declined by 3.33% averagely from 2015 to 2020 (95%CI: -6.25%--0.32%), which might be explained by the declines of the premature death rates of cardiovascular and cerebrovascular diseases [average annual percentage change (AAPC)=-3.23%, 95%CI: -6.32%--0.05%] and cancer (AAPC=-3.58%,95%CI:-6.83%--0.21%). The average decline rate in women (AAPC=-4.19%,95%CI:-7.56%- -0.70%) was higher than that in men (AAPC=-2.92%,95%CI: -5.65%--0.11%). Conclusions: The premature death rate of 4 major chronic diseases showed a downward trend in Ji'nan from 2015 to 2020. Men should be considered as a key population in the prevention and control of 4 major chronic diseases, and attention should also be paid to the non-significant declines in the premature death rates of chronic respiratory diseases and diabetes.

Objective To explore the effect of air temperature on the hospitalization of rural residents with cardiovascular diseases and its lag effect in Dingxi city. Methods The meteorological data and air pollution data of Dingxi city from 2018 to 2019,as well as the daily hospitalization data of rural residents due to cardiovascular diseases,were collected.The distributed lag non-linear models were employed to analyze the relationship between daily mean air temperature and the number of inpatients with cardiovascular diseases.Meanwhile,stratified analysis was carried out according to gender,age,and disease. Results There was a non-linear relationship between air temperature and the number of hospitalized rural residents with cardiovascular diseases in Dingxi city.The exposure-response curve approximated a bell shape.The curves for different cardiovascular diseases appeared similar shapes,with different temperature thresholds.Low temperature(-7 ℃) and moderately low temperature(0 ℃) exhibited a cumulative lag effect on the number of patients hospitalized with cardiovascular diseases.With a cumulative lag of 7 days at -7 ℃ and 14 days at 0 ℃,the RR values peaked,which were 1.121(95% CI=1.002-1.255) and 1.198(95% CI=1.123-1.278),respectively.With a cumulative lag of 14 days at 0 ℃,the RR values were 1.034(95% CI=1.003-1.077) and 1.039(95% CI=1.004-1.066) for the number of hospitalized patients with ischemic heart disease and heart rhythm disorders,respectively.The cumulative lag effects of moderately high temperature(17 ℃) and high temperature(21 ℃) on ischemic heart disease,heart rhythm disorders,and cerebrovascular disease all peaked on that day.Specifically,the RR values at 17 ℃ and 21 ℃ were 1.148(95% CI=1.092-1.206) and 1.176(95% CI=1.096-1.261) for ischemic heart disease,1.071(95% CI=1.001-1.147) and 1.112(95% CI=1.011-1.223) for heart rhythm disorders,and 1.084(95% CI=1.025-1.145) and 1.094(95% CI=1.013-1.182) for cerebrovascular disease,respectively.There was no cumulative lag effect of air temperature on the number of hospitalized patients with heart failure.In addition,stratified analysis showed that low temperature(-7 ℃) and moderately low temperature(0 ℃) affected the number of hospitalized female patients with cardiovascular diseases,and only moderately low temperature(0 ℃) affected males.The cumulative lag effect of high temperature on females was higher than that on males.Air temperature exhibited a stronger impact on female patients than on male patients. Additionally,the population aged<65 years old was more sensitive to low temperature and high temperature than that aged ≥65 years old. Conclusions Air temperature changes increase the hospitalization risk of rural residents with cardiovascular diseases in Dingxi city,which presents a lag effect.The effects of air temperature on patients hospitalized due to cardiovascular diseases varied among different etiologies,genders,and ages.It is necessary to emphasize on the impact of temperature changes on health in residents,especially for key populations such as females,people aged<65 years old,and those with ischemic heart disease.

Cardiovascular and Cerebrovascular Diseases Induced by Air Pollution / 中国医学科学院学报

Air pollution has severe detrimental effects on public health.A substantial number of studies have demonstrated that air pollution exposure is a risk factor for the occurrence of cardiovascular and cerebrovascular diseases and a cause of non-communicable diseases.Both long-term and short-term exposure to air pollution are associated with respiratory diseases,stroke,coronary artery disease,and diabetes.Aiming to better understand the association,we reviewed the latest studies about the association of air pollution with cardiovascular and cerebrovascular diseases,especially stroke,coronary heart disease,arrhythmia,hypertension,and heart failure,and summarized the underlying mechanisms of the health damage caused by long-term and short-term exposure to air pollution.

Expert consensus on clinical application of GBE50 Dispersible Tablets for ischemic cardiovascular and cerebrovascular diseases / 中国中药杂志

Ginkgo biloba Extract( GBE50) Dispersible Tablets is a new standardized prescription,which is widely used in the treatment of ischemic cardiovascular and cerebrovascular diseases. However,there are still many problems in its clinical application.Rational and safe use of GBE50 Dispersible Tablets is pivotal to the medication safety and clinical prognosis of patients. This consensus has been jointly formulated by clinical experts of traditional Chinese medicine and western medicine in cardiovascular and cerebrovascular diseases and followed the Manual for the Clinical Experts Consensus of Chinese Patent Medicine published by the China Association of Chinese Medicine. The present study identified clinical problems based on clinical investigation,searched the research papers according to PICO clinical problems,carried out evidence evaluation,classification,and recommendation by GRADE system,and reached the expert consensus with nominal group technique. The consensus combines evidence with expert experience. Sufficient evidence of clinical problems corresponds to " recommendations",while insufficient evidence to " suggestions". Safety issues of GBE50 Dispersible Tablets,such as indications,usage and dosage,and medication for special populations,are defined to improve clinical efficacy,promote rational medication,and reduce drug risks. This consensus needs to be revised based on emerging clinical issues and evidencebased updates in practical applications in the future.
