Elderly Neurogenic Orthostatic Hypotension Treated Mainly with Fire Needling on Governor Vessel （督 脉）：A Case Report / 中医杂志

Neurogenic orthostatic hypotension （nOH） is a common neurodegenerative disease， and is usually differentiated as kidney-yang depletion syndrome in traditional Chinese medicine （TCM）. Fire needling on governor vessel （督脉） acupoints as well as Shenshu （BL 23） and Zhishi （BL 52） can dredge the qi and blood of governor vessel， so as to warm yang and unblock the channels， supplement essence and boost marrow. A case of elderly nOH treated by fire needling mainly at governor vessel points， Shenshu （BL 23） and Zhishi （BL 52） was reported. After nearly two months of treatment， the patient's orthostatic blood pressure difference and yang deficiency-related symptoms were significantly improved， and the results of blood pressure monitoring， TCM syndrome scale evaluation and Shenshu （BL 23） area infrared imager detection all showed definite clinical effect.

A community-based cross-sectional survey of orthostatic hypotension among elderly from south India

Background: Orthostatic hypotension (OH) increases the risk of falls and associated morbidity and mortality in elderly. Hence, determining the prevalence of OH and its associated factors is important, especially in understudied LMIC settings. Methods: A community-based cross-sectional study was conducted among randomly selected 240 community-dwelling elderly from Thiruvananthapuram, Kerala. The OH symptoms were assessed by standard clinical measurements and frailty was assessed by modified Fried frailty phenotype. Logistic regression analysis was conducted to assess the factors associated with OH. Results: The prevalence of OH and frailty among participants was 9.6 and 29.2 percent respectively. In the first minute, OH was associated with increased odds of falls (OR ¼ 1.97 [95%CI ¼ 1.05, 3.72]). Increase in number of co-morbidities (ORadj ¼ 1.82 [95%CI ¼ 1.36, 2.48]), number of medicines used (ORadj ¼ 1.73 [95%CI ¼ 1.28, 2.34]), and orthostatic intolerance (ORadj ¼ 3.67 [95%CI ¼ 1.13, 11.94]) increased the odds of having OH. Elderly with diabetes (ORadj ¼ 4.81 [95%CI ¼ 1.57, 14.77]), hypertension (ORadj ¼ 4.97 [95% CI ¼ 1.01, 24.46]) and cognitive impairment (ORadj ¼ 5.01 [95%CI ¼ 1.40, 18.51]) were at a higher odds of having OH. Conclusions: OH and frailty are prevalent in community dwelling elderly in Thiruvananthapuram district. Frailty may be a risk factor for OH in the first minute. The number of co-morbidities may be an independent risk factor for OH. Hence, elderly people with comorbidities and cognitive impairment may be actively assessed for OH to prevent falls and associated injuries.

Fenotipo motor y disautonomía cardiovascular de pacientes con enfermedad de Parkinson en la consulta de neurología de un hospital en Táchira (Venezuela) / Motor phenotype and cardiovascular dysautonomia in patients with Parkinson's disease from a neurology outpatient clinic in Táchira (Venezuela)

RESUMEN INTRODUCCIÓN: La enfermedad de Parkinson es un trastorno neurodegenerativo frecuente que se caracteriza por manifestaciones de tipo motor y no motor, tales como disautonomía, trastornos del sueño, disfunción sexual, alteraciones psiquiátricas y cognitivas, entre otros. Según su fenotipo motor, se puede clasificada en tremórica dominante (TD), dificultad para la marcha/inestabilidad postural (DMI) y un fenotipo indeterminado. En el estudio se determina la influencia del fenotipo motor en la disautonomía cardiovascular del paciente con Parkinson en los pacientes de la consulta de neurología del hospital del IVSS "Dr. Patrocinio Peñuela Ruiz" entre mayo del 2015 y abril del 2016. METODOS: Estudio observacional, descriptivo, transversal en pacientes mayores de 40 años con EP idiopática. Se evaluó el MDS-UPDRS, Hoehn y Yahr, Scopa-AUT , Hipotensión Ortostática y Rines-Valcardi. RESULTADOS: Se obtuvo una muestra de 57 pacientes; luego de la aplicación de los criterios de inclusión y exclusión se estudiaron 37 sujetos. Todos los pacientes tuvieron algún grado de disautonomía (medida con la escala Scopa-AUT). El Scopa-AUT fue mayor en los pacientes con hipotensión ortostática (p = ,003), observándose igual diferencia para la subescala cardiovascular (p = ,026). Se observó que la neuropatía autonómica (medida con Rines-Valcardi) fue más frecuente en aquellos pacientes con fenotipo DMI (p = < ,001), y que la hipotensión ortostática fue también más frecuente en aquellos pacientes con dicho fenotipo (DMI) (p = ,016). CONCLUSIÓN: La presencia de disautonomía es frecuente en los pacientes con EP; hubo diferencias en la puntuación total y la subescala cardiovascular del Scopa-AUT, de acuerdo CON la presencia de hipotensión ortostática; aquellos sujetos que cursan con fenotipo motor DMI tienen mayor riesgo de presentar hipotensión ortostática y neuropatía autonómica cardíaca.

ABSTRACT INTRODUCTION: Parkinson's disease is a frequent neurodegenerative disorder characterized by motor and non-motor manifestations, such as dysautonomia, sleep disorders, sexual dysfunction, and psychiatric and cognitive disorders. It can be classified according to their motor phenotype in tremor-dominant (TD), postural instability/gait difficulty (DMI), and indeterminate subtypes. This study established the influence of motor phenotype on the cardiovascular dysautonomia of patients with Parkinson's disease from the neurology outpatient clinic at the IVSS hospital "Dr. Patrocinio Peñuela Ruiz," from May 2015 to April 2016. METHODS: Observational, descriptive, cross-sectional study in patients older than 40 years with idiopathic PD. The MDS-UPDRS scale, Hoehn and Yahr scale, Scopa-AUT scale, Orthostatic Hypotension, and RINES-VALCARDI were evaluated. RESULTS: A sample of 57 was obtained, and after applying inclusion and exclusion criteria, 37 subjects were studied. All the patients had some degree of dysautonomia (measured with SCOPA- AUT scale). The SCOPA-AUT was higher in patients with orthostatic hypotension (p= .003), finding this same difference for the cardiovascular subscale (p = .026). Both autonomic neuropathy (measured with RINES-VALCARDI) and orthostatic hypotension were found more frequently on the DMI phenotype (p= <.001 and p=.016). CONCLUSION: Dysautonomia is frequent in PD patients; there was a difference between SCOPA-AUT total score and cardiovascular subscale according to orthostatic hypotension; those with DMI phenotype have a greater risk of orthostatic hypotension and cardiac autonomic neuropathy.

Orthostatic Hypotension and its Relationship with HbA1c Levels in Patients with Diabetes Mellitus

Introduction: For the diagnosis of diabetes mellitus, various tests are available such as FBS (Fasting blood sugar), PPBS ( Post Prandial Blood Sugar), Oral Glucose Tolerance Test, Random Plasma Glucose Test, HBA1c, etc, of which HBA1c is considered to be the most standard test.1,2 As diabetes mellitus can be asymptomatic initially, it can lead to important complications such as neuropathy, nephropathy, retinopathy, cardiovascular diseases, etc if not detected early.3 Postural blood pressure measurement which diagnoses orthostatic hypotension is a cheap, easy and useful tool to predict HBA1c level even in asymptomatic diabetic patients. Methods: This is a randomized cross-sectional study of 100 diabetic patients attending Medicine OPD or admitted in our tertiary care hospital of South Gujarat. Pretested proforma was used to collect data after taking informed consent. Investigations including blood pressure measured with a standard Sphygmomanometer at the end of 3 min after standing and HBA1c as mentioned in the proforma was carried out. Final analysis has been done with Open EPI and SPSS software. Results: 33% of patients of our study population were found with abnormal orthostatic hypotension. Our data shows orthostatic hypotension is directly associated with high HbA1c, longer duration of DM, and higher value of BMI. No correlation was found between age and gender. Conclusion: Among diabetic patients, high HbA1c, prolong duration of DM and high BMI were associated with abnormal orthostatic hypotension, which can be alarming sign of complications of diabetes mellitus.

Orthostatic hypotension: An overlooked but clinically decisive entity

Orthostatic hypotension (OH) is defined as a drop of >20 mm Hg of systolic or >10 mm Hg of diastolic blood pressure (BP) within 3 min of standing from lying position. It is a common geriatric syndrome caused by impaired orthostatic response of BP. Its clinical manifestation can range from dizziness to syncope. It is a common cause of recurrent falls and fracture in older adults. Its etiology ranges from neurological causes such as Parkinson and diabetes to hypovolemia. Drugs, especially cardiovascular drugs are also frequently identified as the cause of OH. The management of OH is primarily nonpharmacological including medication review, dietary, and lifestyle modifications. However, in partially responsive or resistant cases, medications such as fludrocortisone, midodrine, droxidopa, etc., are also used.

Orthostatic changes in blood pressure and survival in elderly cardiopaths

SUMMARY OBJECTIVE: The objective of this study was to analyze the association between orthostatic changes in blood pressure and mortality in elderly cardiopath patients. METHODS: A cohort of 455 elderly cardiopath patients, monitored at a referral outpatient cardiology clinic in Pernambuco, Brazil, from October 2015 to July 2018. The exposure groups were formed according to their orthostatic changes in blood pressure following the requirements of the Brazilian Guidelines for Hypertension. RESULTS: Orthostatic hypotension was present in 46 patients (10.1%), 91 had orthostatic hypertension (20%), and 318 had no orthostatic alterations (69.9%). There were 52 deaths during follow-up. The results demonstrated that there was no statistically significant association between orthostatic hypotension and overall mortality (HR 1.30; 95%CI 0.53-3.14; p=0.567) nor between orthostatic hypertension and overall mortality (HR 0.95; 95%CI 0.65-1.39; p=0.34). Survival in relation to the exposure groups presented no statistically significant difference (p=0.504). CONCLUSION: There was a low frequency of orthostatic hypotension and a mild high frequency of orthostatic hypertension when compared with previous studies, and no association was observed with overall mortality or with the survival time of elderly patients with heart disease.

Relationship between frailty and orthostatic hypotension in the elderly in nursing homes / 中国实用护理杂志

Objective:To understand the predictive effect of orthostatic hypotension on frailty in nursing homes, and the effect of frailty on heart rate and blood pressure in supine positionand orthostatic position.Methods:A total of 214 elderly cases in three nursing homes (the Golden Years of Jinjialing Retirement Life Center, Hangzhou Boyang Pension Service Co., Ltd, Hangzhou Langhe International Medical Care Center) were interviewed by the general information questionnaire, the Frail Scale and Barthel Index. Systolic blood pressure, diastolic blood pressure, and heart rate were measured by electronic sphygmomanometer in supine position and orthostatic position of 1 and 3 minutes.Results:The incidence of frailty combined with orthostatic hypotension was 26.64%(57/214) in the elderly in nursing homes. The incidence of orthostatic hypotension in the robust elderly, pre-frailty and frailty gradually increased, 14.29%(5/35), 20.00%(12/60), 47.90%(57/119). The differences of heart rate and systolic blood pressure in supine position between the elderly with and without frailty were significant ( t=2.16, 3.25, P<0.05), the differences of systolic pressure difference in orthostatic position of 1 and 3 minutes between the elderly with and without frailty were significant ( H=3.16, 4.08, P<0.01). There was significant difference in systolic pressure between the prefrail elderly and the elderly without frailty in lying position ( t=2.02, P<0.05). The differences of systolic and diastolic pressure differences in orthostatic position of 3 minutes between the frail elderly and pre-frail elderly were significant ( H=3.13,2.44, P<0.05). Ordered Logistic regression analysis showed that orthostatic hypotension was a risk factor for frailty ( OR=2.425, 95% CI were 1.133-4.988, P<0.05). Conclusions:Elderly adults with orthostatic hypotension in nursing homes have a higher prevalence of frailty. Frailty also impairs blood pressure regulation during postural changes. Nurses should attach importance to the assessment, education and intervention of frailty and orthostatic hypotension.

Manifestaciones cardiovasculares de la enfermedad de Parkinson: revisión de la literatura / Cardiovascular manifestations of Parkinson's disease: literature review

RESUMEN La enfermedad de Parkinson es la segunda enfermedad neurodegenerativa más prevalente en el mundo, y sus manifestaciones cardinales son la bradicinesia, el temblor y la rigidez. Aunque ha sido considerado un trastorno motor, actualmente se considera como un trastorno neurológico complejo que afecta diferentes sistemas, por lo que genera manifestaciones motoras y no motoras variadas, además de manifestaciones autonómicas sistémicas. Las manifestaciones cardiovasculares en pacientes con enfermedad de Parkinson son frecuentes y, además, provocan un gran impacto sobre la calidad de vida. A continuación, se realiza una revisión narrativa de las principales manifestaciones cardiovasculares de la enfermedad de Parkinson, y de sus mecanismos fisiopatológicos.

SUMMARY Parkinson's disease is the second most prevalent neurodegenerative disease in the world and is characterized by bradykinesia, tremor, rigidity, and postural instability. Although it has been considered as a motor system disease, it is currently considered as a complex neurological disease with different motor, non-motor, and autonomic manifestations. Cardiovascular manifestations in patients with Parkinson's disease are frequent and they have a great impact on quality of life. This article seeks to carry out a narrative review of the pathophysiological mechanisms and the main cardiovascular clinical manifestations in patients with Parkinson's disease.

Pure autonomic failure: a case report / 中华神经科杂志

Pure autonomic failure (PAF) is an α-synucleinopathy featured by slowly progressive autonomic failure. A patient who presented with orthostatic hypotension associated dizziness and syncope, postprandial hypotension, supine hypertension and anhidrosis, was hospitalized. The patient did not show incontinence, urinary retention, constipation, ataxia, and extrapyramidal symptoms. In combination of the description of the patient′s symptoms with PAF related references, the pathogenesis, clinical manifestations, diagnosis and differential diagnosis of PAF and its relationship with other α-synucleinopathies were demonstrated in this report.

Efficacy of Midodrine on Hemodynamics

Objectives: To assess the use of Midodrine among patients with orthostatic hypotension and withdrawal vasopressin in King Abdulaziz Medical City (KAMC), demonstrate the effectiveness and safety of Midodrine and detect side effects to provide clear evidence of the efficacy and safety of the drug. Methods: A retrospective cohort study was done in King Abdulaziz Medical City in Riyadh (Saudi Arabia). The study targeted adult patients who suffered from hypotension between January 2015 and January 2018. The data was extracted using the BESTCare system. Result: A total of 173 patients were included (55.5% male and 44.5% female). The mean age of the study participants was 67.34 ± 16.0 years. The differences in patients’ parameters before and after midodrine administration were detected and analyzed. The mean difference in hemoglobin (g/l) level was significantly changed before (94.97 ± 21.9) and after (90.84 ± 20.4) the use of Midodrine (p=0.031). However, there were no significant changes in the level of the other parameters before and after the use of Midodrine. The mean dose of Midodrine was 5.3 mg, with mean treatment duration of 41.5 days, and mean hospitalization of 28.7 days. For the medication history, 8% of patients were on betablockers (n=97), 5%were on diuretics (n=64), and 2% were on calcium channel blockers (n=19). Conclusion: Our data suggest that the administration of Midodrine does not affect patients’ hemodynamics significantly; however, it has a notable effect on decreasing hemoglobin levels.

Hipotensión ortostática y deterioro cognitivo/demencia en adultos / Orthostatic hypotension and cognitive impairment/dementia in adults

A narrative review was made on orthostatic hypotension and cognitive impairment / dementia. The PubMed and PsycInfo databases were used and the original studies published in English between 2013 and 2018 were identified. The keywords used during the search were the following: "orthostatic hypotension", "adults" and "cognitive" / "cognitive impairment" / "dementia". We found 20 original studies that explore the relationship between orthostatic hypotension and cognitive / dementia. Most of the studies reviewed provide evidence in favor of the existence of an association between orthostatic hypotension and cognitive impairment / dementia in adults: 8 out of 11 papers provide evidence in favor of the existence of an association between orthostatic hypotension and cognitive impairment, 6 out of 7 papers provide evidence in favor of the existence of an association between orthostatic hypotension and dementia, and 2 out of 2 papers provide evidence in favor of the existence of an association between orthostatic hypotension and mild cognitive impairment. The authors suggest that both brain hypoperfusion and cellular damage could partially explain the link between orthostatic hypotension and the cognitive disorders described in the literature. Future studies may identify mechanisms that explain the association between orthostatic hypotension and cognitive impairment / orthostatic hypotension and dementia in adults to reduce the risk of cognitive impairment / dementia or at least slow down its progression

Se realizó una revisión narrativa sobre la hipotensión ortostática (HTO) y el deterioro cognitivo/la demencia. Se utilizaron las bases de datos PubMed y PsycInfo. Se identificaron los estudios originales publicados en idioma inglés entre 2013 y 2018, inclusive. Las palabras clave utilizadas durante la búsqueda fueron las siguientes: "orthostatic hypotension", "adults" and "cognitive"/ "cognitive impairment"/ "dementia". Se encontraron 20 estudios originales que exploran la relación entre la HTO y el/la deterioro cognitivo/demencia. La mayoría de los trabajos revisados aportan datos a favor de la existencia de una asociación entre HTO y deterioro cognitivo/demencia en adultos: 8 de 11 trabajos suministran información a favor de la existencia de una asociación entre HTO y deterioro cognitivo, 6 de 7 estudios brindan datos a favor de la existencia de una asociación entre HTO y demencia, y 2 trabajos aportan datos a favor de la asociación entre HTO y deterioro cognitivo leve. Los autores sugieren que tanto la hipoperfusión cerebral como el daño celular podrían explicar, al menos parcialmente, la vinculación entre la HTO y las alteraciones cognitivas descriptas en la bibliografía. Estudios realizados en el futuro podrán identificar los mecanismos que expliquen la asociación entre HTO y deterioro cognitivo, así como entre HTO y demencia en adultos, con el fin de reducir el riesgo de deterioro cognitivo/demencia o, al menos, enlentecer su progresión.

Neuropatia autonômica cardiovascular em pacientes com diabetes mellitus: perspectivas atuais / Cardiovascular autonomic neuropathy in patients with diabetes mellitus: current outlook

A neuropatia autonômica cardíaca (NAC) é uma complicação comum do diabetes mellitus (DM) e frequentemente, subdiagnosticada. A NAC está associada ao aumento da mortalidade, cardiovascular e renal, doença renal crônica e maior morbidade em pacientes com DM. Apesar dessas consequências, muitas vezes, a NAC permanece sem diagnóstico por um período prolongado. Isso geralmente porque a doença é assintomática até a fase avançada, bem como pela falta de informações e de estratégias de triagem. Clinicamente NAC se manifesta por distúrbios funcionais ou condições clínicas que envolvem desajuste das atividades reflexas cardiovasculares, tais como taquicardia em repouso, intolerância ao exercício, hipotensão ortostática, instabilidade cardiovascular intraoperatória, disfunção elétrica do coração traduzida por arritmias e isquemia miocárdica silenciosa. Essas alterações comprometem a qualidade de vida e a sobrevida dos pacientes. A NAC, segundo sua evolução, pode ser subdividida em subclínica (fase em que predominam alterações funcionais reversíveis) e clínica (quando as alterações neuronais estruturais estão plenamente estabelecidas). A avaliação da integridade do sistema nervoso autonômico é realizada por meio de exploração da atividade parassimpática, analisando o comportamento da frequência cardíaca (FC) em resposta à respiração profunda, ortostatismo ou manobra de Valsalva. A atividade simpática é explorada por meio de aferição da pressão arterial em resposta a mudança de postura (ortostatismo) e esforço isométrico. A análise da variabilidade da frequência cardíaca (VFC), no domínio do tempo, no domínio da frequência e por métodos gráficos complementam essa avaliação. Neste artigo de revisão, analisamos recentes informações sobre a epidemiologia, manifestações clínicas, diagnóstico, e tratamentos da NAC

Cardiac autonomic neuropathy (CAN) is a common and often-underdiagnosed complication of diabetes mellitus (DM). CAN is associated with increased mortality, cardiovascular disease, chronic kidney disease, and morbidity in patients with DM, but despite these significant consequences CAN often remains undiagnosed for a prolonged period. This is commonly due to the disease being asymptomatic until the later stages, as well as a lack of easily available screening strategies. Clinically, CAN is manifested by functional disorders or clinical conditions that involve maladjustment of cardiovascular reflex activities, such as tachycardia at rest, exercise intolerance, orthostatic hypotension, intraoperative cardiovascular instability, electrical dysfunction of the heart translated by arrhythmias and silent myocardial ischemia. These changes compromise patients' quality of life and survival. CAN, according to its evolution, can be subdivided into subclinical (phase in which reversible functional changes predominate) and clinical (when structural neuronal changes are fully established). The assessment of the integrity of the autonomic nervous system is performed by exploring parasympathetic activity, analyzing the heart rate in response to deep breathing, orthostatism or Valsalva maneuver. Sympathetic activity is explored by measuring blood pressure in response to a change in posture (orthostatism) and isometric effort. The analysis of heart rate variability (HRV), in the time domain, in the frequency domain and by graphic methods, complement this assessment. In this article, we review the latest developments in the epidemiology, pathogenesis, diagnosis, consequences, and treatments of CAN in patients with DM.

SUMMARY Symptoms due to autonomic dysfunction are common in Parkinson's Disease, being present in all phases of the disease. It covers a wide variety of symptoms including gastrointestinal, urinary, erectile dysfunction, and orthostatic hypotension among others, generating disability and deterioration in quality of life. Fortunately, with non-pharmacological and pharmacological interventions, these symptoms can improve substantially, making the evaluation of these symptoms vital for the patient's well-being.

Orthostatic hypotension is associated with new-onset atrial fibrillation: Systemic review and meta-analysis

Introduction Orthostatic hypotension (OH) is common among elderly patients. Its presence may herald severe underlying comorbidities and be associated with a higher risk of mortality. Interestingly, recent studies suggest that OH is associated with new-onset atrial fibrillation (AF). However, a systematic review and meta-analysis of the literature has not been performed. We assessed the association between AF and OH through a systematic review of the literature and a meta-analysis. Methods We comprehensively searched the databases of MEDLINE and EMBASE from inception to November 2018. Published prospective or retrospective cohort studies that compared new-onset AF between male patients with and without OH were included. Data from each study were combined using the random-effects, generic inverse-variance method of DerSimonian and Laird to calculate risk ratios and 95% confidence intervals. Results Four studies from October 2010 to March 2018 were included in the meta-analysis involving 76,963 subjects (of which 3318 were diagnosed with OH). The presence of OH was associated with new-onset AF (pooled risk ratio 1.48; 95% confidence interval [1.21, 1.81], p?< 0.001; I2 = 69.4%). In hypertensive patients, analysis revealed an association between OH and the occurrence of new-onset AF (OR 1.46; 95% CI [1.27, 1.68], p < 0.001 with I2 = 0). Conclusions OH was associated with new-onset AF up to 1.5-fold compared with those subjects without OH. The interplay between OH and AF is likely bidirectional.

Alteration of cardiovascular autonomic activity in type 2 diabetes mellitus

Background: Diabetes mellitus (DM) is a clinical syndrome characterized by hyperglycaemia due to absolute or relative insulin deficiency. Cardiovascular autonomic neuropathy (CAN) invokes potentially life-threatening outcomes especially in poorly controlled diabetic patients. This study was to evaluate the prevalence of CAN in diabetic patients and its relationship with QTc interval.Methods: This observational study of two year duration was included total 123 patients of more than 30 (thirty) years and up to 60 (sixty) years of age who were presented with diabetic mellitus (DM) those were evaluated for CAN using four distinct clinical tests-Resting heart rate (RHR), test for orthostatic hypotension (OH), hand gripping test (HGT) and QTc interval on ECG. Data were analyzed with statistical package for social sciences (SPSS), version 23.Results: The mean age of all 103 studied patients was 48.94±8.69 years; Mostly patients belong to 50-60 years of age and the majority was males (69.0%). Out of 103 72.8% patients were reported with CAN (51 males and 24 females) and without CAN were 27.2.0% (20 males and 8 females), 36% of patients of Definite Parasympathetic neuropathy, 25% Normal and 20% of Sympathetic neuropathic patients. HbA1c level increases the danger of CAN also. QTc interval is a reliable indicator for the presence of CAN.Conclusions: Duration of diabetes is directly proportional to the prevalence of CAN. Various cardiac autonomic function tests detect CAN.

Research progress on blood pressure regulation disorder in Parkinson′s disease / 中华神经科杂志

Parkinson′s disease (PD) is the second most common neurodegenerative disease following Alzheimer′s disease, including motor and non-motor symptoms. Non-motor symptoms are mainly autonomic nervous dysfunction, which occur about 5-20 years earlier than motor symptoms. Abnormal blood pressure regulation is a common manifestation of autonomic nervous dysfunction. Long-term abnormal blood pressure can seriously hamper the quality of life and trigger deterioration of motor symptoms. Thus, it is necessary to obtain correct understanding of the etiology, mechanism, clinical features, diagnosis and treatment of PD with blood pressure regulation disorders in order to reduce the mortality rate and the burden of medical health. This article reviews the influencing factors, characteristics, mechanisms and management of PD with blood pressure regulation disorder.

Autonomic dysfuction and its correlation research in patients with Parkinson’s disease combined with orthostatic hypotension / 临床神经病学杂志

To investigate the autonomic dysfunction in patients with Parkinson’s disease ( PD) combined with orthostatic hypotension (OH). Methods Seventy-six PD patients were selected and divided into PD-OH group (n=40) and non-OH group (n=36) after the measurement of blood pressure in the supine to standing position. The scales for outcomes in PD-autonomic test (SCOPA-AUT) was used to evaluate the patients in the two groups. Results There were significant differences in age, duration and Hoehn-Yahr stage between the two groups (all P<0.05). The total value of SCOPA-AUT in the PD-OH group was significantly higher than that in the non-OH group ( P< 0.05 ). The scores of digestive system, urinary system, cardiovascular system, sympathetic/parasympathetic system and sexual function of SCOPA-AUT in the PD-OH group were all significantly higher than those in the non-OH group (all P<0.05). Conclusion The autonomic dysfunction of PD patients with OH is more serious than that of PD patients without OH, and clinical diagnosis and management of PD patients with OH should be strengthened.

Fatores associados à hipotensão ortostática em adultos: estudo ELSA-Brasil / Factors associated with orthostatic hypotension in adults: the ELSA-Brasil study / Factores asociados a la hipotensión ortostática en adultos: estudio ELSA-Brasil

Resumo: O objetivo foi investigar os fatores associados à presença de hipotensão ortostática em 14.833 indivíduos de 35-74 anos. Estudo transversal realizado com os dados da linha de base (2008-2010) do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). O teste postural foi realizado após repouso de 20 minutos na posição supina e adoção ativa da postura ortostática. A pressão arterial foi medida em supino e aos três minutos de ortostase com aparelho oscilométrico (HEM 705 CP, Omron, São Paulo, Brasil). A hipotensão ortostática foi definida por queda ≥ 20mmHg na pressão arterial sistólica e/ou queda ≥ 10mmHg na pressão arterial diastólica. As covariáveis analisadas foram sexo, faixa etária, raça/cor, escolaridade, estado nutricional, circunferência da cintura, alteração no índice tornozelo braquial, velocidade de onda de pulso, pressão arterial sistólica e diastólica, hipertensão, diabetes, uso de anti-hipertensivos, colesterol, triglicérides, sorologia para a doença de Chagas, ocorrência de sintomas e variação de frequência cardíaca no teste postural, relato de doença cardíaca, infarto agudo do miocárdio (IAM)/revascularização e acidente vascular cerebral. A hipotensão ortostática foi significativamente associada à maior faixa etária, OR = 1,83 (IC95%: 1,14-2,95); alteração no índice tornozelo braquial, OR = 2,8 (IC95%: 1,13-6,88), IAM/revascularização, OR = 1,70 (IC95%: 1,01-2,87); relato de doença cardíaca, OR = 3,03 (IC95%: 1,71-5,36); pressão arterial sistólica aumentada, OR = 1,012 (IC95%: 1,006-1,019); sorologia positiva para a doença de Chagas, OR = 2,29 (IC95%: 1,23-4,27) e ocorrência de sintomas na mudança postural, OR = 20,81 (IC95%: 14,81-29,24). A presença de hipotensão ortostática pode ser alerta de potencial comprometimento cardiovascular, e, portanto, uma ferramenta de rastreamento e prevenção.

Abstract: This study aimed to investigate factors associated with orthostatic hypotension in 14,833 individuals 35-74 years of age. This was a cross-sectional study of baseline data (2008-2010) from the Longitudinal Study of Adult Health (ELSA-Brasil). Postural testing was performed after 20 minutes resting in supine position and active adoption of orthostatic posture. Blood pressure was measured in supine position and at 3 minutes in orthostatic position with an oscillometer (HEM 705 CP, Omron, São Paulo, Brazil). Orthostatic hypotension was defined as a drop of ≥ 20mmHg in systolic blood pressure and/or a drop of ≥ 10mmHg in diastolic blood pressure. The target covariates were sex, age bracket, race/color, schooling, nutritional status, waist circumference, alteration in the ankle-brachial index, pulse wave velocity, systolic and diastolic blood pressure, hypertension, diabetes, use of antihypertensives, cholesterol, triglycerides, Chagas disease serology, symptoms, and heart rate variation in the postural test, self-reported heart disease, acute myocardial infarction (AMI)/revascularization, and stroke. Orthostatic hypotension was significantly associated with higher age bracket, OR = 1.83 (95%CI: 1.14-2.95); alteration in the ankle-brachial index, OR = 2.8 (95%CI: 1.13-6.88); AMI/revascularization, OR = 1.70 (95%CI: 1.01-2.87); report of heart disease, OR = 3.03 (95%CI: 1.71-5.36); increased systolic blood pressure, OR = 1.012 (95%CI: 1.006-1.019); positive Chagas disease serology, OR = 2.29 (95%CI: 1.23-4.27); and occurrence of symptoms with postural change, OR = 20.81 (95%CI: 14.81-29.24). Presence of orthostatic hypotension can be a warning sign for cardiovascular disorders and thus a useful tool for screening and prevention.

Resumen: El objetivo fue investigar los factores asociados a la presencia de hipotensión ortostática en 14.833 individuos de 35-74 años. Se realizó un estudio transversal con los datos de la línea de base (2008-2010) del Estudio Longitudinal de Salud del Adulto (ELSA-Brasil). El examen postural se realizó tras un reposo de 20 minutos en posición supina y la adopción activa de la postura ortostática. Se midió la presión arterial en supino y a los 3 minutos de ortostasis con aparato oscilométrico (HEM 705 CP, Omron, São Paulo, Brasil). La hipotensión ortostática se definió por la caída ≥ 20mmHg en la presión arterial sistólica y/o caída ≥ 10mmHg en la presión arterial diastólica. Las covariables analizadas fueron sexo, franja de edad, raza/color, escolaridad, estado nutricional, circunferencia de la cintura, alteración en el índice tobillo-brazo, velocidad de onda de pulso, presión arterial sistólica y diastólica, hipertensión, diabetes, uso de antihipertensivos, colesterol, triglicéridos, serología para a enfermedad de Chagas, ocurrencia de síntomas y variación de frecuencia cardíaca en el examen postural, informe de enfermedad cardíaca, infarto agudo de miocardio (IAM)/revascularización y accidente vascular cerebral. La hipotensión ortostática estuvo significativamente asociada a la mayor franja de edad, OR = 1,83 (IC95%: 1,14-2,95); alteración en el índice tobillo-brazo, OR = 2,8 (IC95%: 1,13-6,88), IAM/revascularización, OR = 1,70 (IC95%: 1,01-2,87); relato de enfermedad cardíaca, OR = 3,03 (IC95%: 1,71-5,36); presión arterial sistólica aumentada, OR = 1,012 (IC95%: 1,006-1,019); serología positiva para a enfermedad de Chagas, OR = 2,29 (IC95%: 1,23-4,27) y ocurrencia de síntomas en el cambio postural, OR = 20,81 (IC95%: 14,81-29,24). La presencia de hipotensión ortostática puede ser una alerta de potencial comprometimiento cardiovascular, y, por tanto una herramienta de seguimiento y prevención.

Segurança do paciente: alterações da hemoglobina e ferro sérico após lipoaspiração e/ou abdominoplastia / Patient safety: changes in hemoglobin and serum iron after liposuction and/or abdominoplasty

Introdução: A lipoaspiração é o sendo segundo procedimento mais realizado no Brasil. Com os avanços da técnica, melhores equipamentos e aumento da segurança no ambiente cirúrgico, passaram-se a ser lipoaspiradas grandes áreas. Contudo, existe uma preocupação com a segurança do paciente. Comitês de segurança têm feito recomendações sobre a infiltração, anestesia, seleção do paciente, volume aspirado, entre outros. A Sociedade Brasileira de Cirurgia Plástica e o Conselho Federal de Medicina também determinaram parâmetros de volumes de segurança do aspirado e superfície corporal aspirada. Ainda assim, a literatura de apoio para as recomendações é escassa. O objetivo é avaliar as alterações dos níveis de hemoglobina, ferro sérico e proteínas totais no pré e pós-operatório mediato (7-10 dias), assim como seus reflexos nos pacientes. Métodos: Realizamos um estudo prospectivo, com pacientes submetidos à lipoaspiração isolada e associada à dermolipectomia abdominal, por indicações estéticas. Avaliamos 30 pacientes, sendo coletados dados demográficos, peso, Índice de Massa Corporal, níveis de hemoglobina, ferro sérico e proteínas totais, no pré-operatório, e entre 7 a 10 dias de pós-operatório. Resultados: A queda da hemoglobina foi entre 2-6g/dl, com média de 3,1g/dl aos 7-10 dia de PO. Tivemos como valor mínimo de hemoglobina 7,8g/dl no pós-operatório com 7-10 dias, enquanto o ferro sérico apresentou redução média de 44,87g/dl. Conclusão: A redução no nível da hemoblogina foi responsável pela sintomatolgia clinica apresentada. A reposição de ferro se mostrou necessária no pós-operatório imediato.

Introduction: Liposuction is the second commonest procedure performed in Brazil. The scope for liposuction has broadened with advances in the technique, with better equipment, and increased safety in the surgical environment. However, there are concerns about patient safety. Safety committees have made recommendations on various aspects of the procedure including infiltration, anesthesia, patient selection, and aspirated volume. The Brazilian Society of Plastic Surgery and the Federal Council of Medicine have also determined the parameters for aspiration safety volumes, and for the aspiration of body surface. However, supporting literature for the recommendations is scarce. The objective is to evaluate changes in hemoglobin, serum iron, and total protein levels in the peri-operative days (between 7 and 10 days), in addition to its impact in patients. Methods: We performed a prospective study, with patients submitted to either liposuction alone, or in conjunction with abdominal dermolipectomy for esthetic indications. We evaluated 30 patients, collecting their demographic data, weight, body mass index, hemoglobin, serum iron, and total protein levels in both, the pre-operative period, and between 7 and 10 post-operative days. Results: The fall in hemoglobin levels were between 2 and 6 g /dL, with an average of 3.1 g /dL between 7 and 10 post-operative days . A minimum hemoglobin value of 7.8 g/dL was noted between 7 and 10 days after surgery, while the mean reduction of serum iron was found to be 44.87 g/dL. Conclusion: The reduction in hemoglobin levels was responsible for the clinical symptoms. Iron supplementation was required in the immediate post-operative period.
