Advances of pathogenesis and drug development in amyotrophic lateral sclerosis / 中国药理学通报

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease affecting both upper and lower motor neurons. ALS patients develop progressive muscle atrophy, muscle weak and paralysis, finally died of respiratory failure. ALS is characterized by fast aggression and high mortality. What' s more, the disease is highly heterogeneous with unclear pathogenesis and lacks effective drugs for therapy. In this review, we summarize the main pathological mechanisms and the current drugs under development for ALS, which may provide a reference for the drug discovery in the future.

Complicaciones tromboembólicas y hemorrágicas en pacientes portadores de prótesis valvulares del corazón en un centro de tercer nivel. ¿Qué hemos aprendido? / Thromboembolic and hemorrhagic complications in patients with prosthetic heart valves at third level care center. What have we learned?

Resumen Antecedentes: El reemplazo valvular por prótesis mecánicas o biológicas implica riesgo de tromboembolismo y complicaciones hemorrágicas. Objetivo: Determinar las complicaciones relacionadas con la terapia de anticoagulación complementaria y la probabilidad de riesgo en pacientes portadores de prótesis valvulares del corazón. Métodos: Se estudiaron 163 pacientes entre 2002 y 2016, portadores de prótesis mecánicas y biológicas, quienes recibieron antagonistas de la vitamina K posterior al egreso hospitalario. La terapia de anticoagulación se categorizó en óptima y no óptima conforme a los valores de INR previos a las complicaciones. Fueron excluidos los pacientes con comorbilidades y otros factores de riesgo de trombosis y/o sangrado. Resultados: a 68.7 % de los pacientes se les colocó prótesis mecánica y a 31.3 %, biológica (p ≤ 0.001); 25.2 % presentó las complicaciones motivo de estudio (p ≤ 0.001), hemorrágicas en 48.8 %, tromboembólicas en 26.8 % y de ambos tipos en 24.4 % (riesgo relativo = 4.229); a 95.1 % de los pacientes con complicaciones se les colocó prótesis mecánica y a 4.9 %, biológica (p = 0.005); 49.7 % presentó INR no óptimo (p ≤ 0.001). Conclusiones: Ante riesgo alto de complicaciones tromboembólicas y hemorrágicas, la elección de las prótesis valvulares, la prevención y el seguimiento son prioridades, principalmente en quienes requieren terapia de anticoagulación.

Abstract Background: Heart valve replacement surgery with mechanical or biological prostheses entails a risk of thromboembolism and bleeding complications. Objective: To determine the complications related to complementary anticoagulation therapy and the probability of risk. Methods: One-hundred and sixty-three patients who underwent heart valve replacement between 2002 and 2016 with either mechanical or biological prostheses, and who received vitamin K antagonists after hospital discharge, were studied. Anticoagulation therapy was categorized into optimal and non-optimal according to INR values prior to the development of complications. Patients with comorbidities and other risk factors for thrombosis and/or bleeding were excluded. Results: In total, 68.7 % of patients received mechanical prostheses, and 31.3 %, biological prostheses (p ≤ 0.001); 25.2 % experienced the complications that motivated the study (p ≤ 0.001), which were hemorrhagic in 48.8 %, thromboembolic in 26.8 %, and of both types in 24.4 % (relative risk = 4.229). Among the patients with complications, 95.1 % received mechanical prostheses, and 4.9 %, biological (p = 0.005); non-optimal INR was identified in 49.7 % (p ≤ 0.001). Conclusions: Given the high risk of thromboembolic and hemorrhagic complications, valve prostheses must be carefully chosen, and care priorities should include prevention and follow-up, especially in those patients who require anticoagulation therapy.

Clinical value of Hospital Admission Risk Profile (HARP) and the Identification of Seniors at Risk (ISAR) scales to predict hospital-associated functional decline in an acute geriatric unit in Colombia

Background: Older adults admitted to a hospital for acute illness are at higher risk of hospital-associated functional decline during stays and after discharge. Objective: This study aimed to assess the calibration and discriminative abilities of the Hospital Admission Risk Profile (HARP) and the Identification of Seniors at Risk (ISAR) scales as predictors of hospital-associated functional decline at discharge in a cohort of patients older than age 65 receiving management in an acute geriatric care unit in Colombia. Methods: This study is an external validation of ISAR and HARP prediction models in a cohort of patients over 65 years managed in an acute geriatric care unit. The study included patients with Barthel index measured at admission and discharge. The evaluation discriminate ability and calibration, two fundamental aspects of the scales. Results: Of 833 patients evaluated, 363 (43.6%) presented hospital-associated functional decline at discharge. The HARP underestimated the risk of hospital-associated functional decline for patients in low- and intermediate-risk categories (relation between observed/expected events (ROE) 1.82 and 1.51, respectively). The HARP overestimated the risk of hospital-associated functional decline for patients in the high-risk category (ROE 0.91). The ISAR underestimated the risk of hospital-associated functional decline for patients in low- and high-risk categories (ROE 1.59 and 1.11). Both scales showed poor discriminative ability, with an area under the curve (AUC) between 0.55 and 0.60. Conclusions: This study found that HARP and ISAR scales have limited discriminative ability to predict HAFD at discharge. The HARP and ISAR scales should be used cautiously in the Colombian population since they underestimate the risk of hospital-associated functional decline and have low discriminative ability.

Antecedentes: los adultos mayores ingresados en un hospital por una enfermedad aguda tienen un mayor riesgo de deterioro functional hospitalario durante su estancia y después del alta. Objetivo: este estudio tuvo como objetivo evaluar las capacidades de calibración y discriminación de las escalas Hospital Admission Risk Profile (HARP) e Identification of Seniors at Risk (ISAR) como predictores de deterioro funcional hospitalario al alta en una cohorte de pacientes mayores de 65 años que recibieron manejo en una unidad geriátrica de agudos en Colombia. Métodos: este estudio es una validación externa de los modelos de predicción ISAR y HARP en una cohorte de pacientes mayores de 65 años atendidos en una unidad geriátrica de agudos. El estudio incluyó pacientes con índice de Barthel medido al ingreso y al alta y la evaluación de la capacidad de discriminación y calibración, dos aspectos fundamentales para esta medición. Resultados: de 833 pacientes evaluados, 363 (43.6%) presentaron deterioro funcional hospitalario al momento del alta. La escala HARP subestimó el riesgo de deterioro funcional hospitalario para los pacientes en las categorías de riesgo bajo e intermedio (relación entre eventos observados /esperados (ROE) 1.82 y 1.51, respectivamente). El HARP sobrestimó el riesgo de deterioro funcional hospitalario para pacientes en la categoría de alto riesgo (ROE 0.91). El ISAR subestimó el riesgo de deterioro hospitalario para pacientes en categorías de bajo y alto riesgo (ROE 1.59 y 1.11). Ambas escalas mostraron una pobre capacidad de discriminación, con un área bajo la curva (AUC) entre 0.55 y 0.60. Conclusiones: este estudio encontró que las escalas HARP e ISAR tienen una capacidad de discriminación limitada para predecir deterioro funcional hospitalario al alta. Las escalas HARP e ISAR deben usarse con cautela en la población colombiana ya que subestiman el riesgo de deterioro funcional hospitalario y tienen baja capacidad de discriminación.

Impaired Cognition – A Menace to Aging

Cognition is defined as mental process of acquiring knowledge and understanding through thought, experi-ence and senses. It is an age-related degenerative condition, as the age advances, individuals experience dete-riorative changes in their cognitive abilities. It is estimated that nearly four fifth of the elderly above 60 years of age will be living in developing countries like Africa, Asia by 2050, thereby placing the developing countries to face threat of cognitive impairment among elderly when compared to developed countries. The result of striking increase in aging population of India, it is expected to have a substantial increase in elderly suffering from cognitive impairment. This review involves discussing the various causes, pathophysiology, modifiable and non-modifiable risk factors associated with this increasing cognitive deterioration in elderly people, di-agnostic criteria, and preventive methods. This review will help in better understanding of the cognitive im-pairment in elderly people. Better understanding of the disease helps in better treatment modalities.

Correlation study between early neurological deterioration and cerebral microbleeds in patients with acute small artery occlusion / 中国医师进修杂志

Objective:To investigate the relationship between the degree and location of cerebral microbleeds (CMBs) and the early neurological deterioration (END) within 72 h after admissionin in patients with acute small artery occlusive stroke (SAO).Methods:Patients with first-onset SAO hospitalized in Changzhou Second People′s Hospital from July 2020 to January 2021 were retrospectively enrolled. All patients completed the head magnetic resonance imaging including susceptibility weighted imaging. Collected baseline data, and evaluated the National Institutes of Health Stroke Scale (NHISS) scores before admission and within 72 h after onset. Patients were divided into END group and no END group according to whether NIHSS scores increased by ≥3 within 72 h after admission. The baseline characteristics were compared between these two groups. Moreover, the correlation between the degree and location of CMBs and END were analyzed by multivariate Logistic regression.Results:A total of 163 first-episode SAO patients were enrolled. There were 47 patients (28.83%) with END. In END group, there were 35 patients (74.47%) with CMBs which was higher than those in non-END group [42 patients (36.21%)]. In END group, there were 21 patients (44.68%) with severe CMBs, 11 patients (23.41%) with basal ganglia CMBs, 16 patients (34.04%) with mixed CMBs, which were all higher than those in non-END group [5 patients (4.31%) with severe CMBs, 9 patients (7.76%) with basal ganglia CMBs, and 13 patients (11.21%) with mixed CMBs]. The difference was statistically significant ( P<0.05). After adjusting for triglyceride, location of infarcated lesions, and the degree of WMHs, further Logistic regression analysis revealed that severe CMBs ( OR = 6.139, 95% CI 1.377 - 27.375, P = 0.017), basal ganglia CMBs ( OR = 5.253, 95% CI 1.105 - 24.975, P = 0.037) and mixed CMBS ( OR = 5.098, 95% CI 1.197 - 21.704, P = 0.028) were independent risk factors of END in SAO patients. Conclusions:The location and degree of CMBs are closely related to the occurrence of END in patients with SAO. Severe CMBs, basal ganglia CMBs and mixed CMBs may be the effective predictors of END in patients with SAO.

Implications of five-year outcomes of PERIGON trial for bioprosthetic aortic valve replacement / 中国胸心血管外科临床杂志

@#For patients with aortic valve disease who require replacement of their native valve, surgical aortic valve replacement (SAVR) has been the standard of care. Due to the hemorrhage and thromboembolic risks of long-term anticoagulation therapy for mechanical prosthesis, bioprosthetic aortic valve replacement (AVR) has a trend to be used in younger patients, which raising the concern for the durability of bioprosthetic valves. The newly published 5-year outcomes of PERIGON trial, with no structural valve deterioration, again demonstrated the favorable durability of the new generation bioprosthetic valves, further providing the evidence of using bioprosthetic AVR in younger patients. At the meantime, the rapid progress of transcatheter aortic valve implantation (TAVI) has brought a new treatment option. For younger patients with low risks, choosing SAVR or TAVI becomes a critical decision. This paper reviews the outcomes of PERIGON trial and its implications to the clinical practice and research of bioprosthetic AVR.

Dementia: Trauma and loss of personhood vs Family as recuperative space

The paper looks at the exploration in three Indian novels in English, of the hitherto glorified Indian family through the paradigm of dementia, examines the strained space called “home” in the shadow of dementia, and its transformation into a recuperative space with the help of support systems other than immediate family members. These three recent texts in Indian writing in English have discussed this crippling condition; which earlier authors shied away from. Anuradha Roy’s The Folded Earth (2012), Ranjit Lal’s Our Nana was a Nutcase (2015), and Pankaj Varma’s Silver Haze (2014), focus on the life-changing effects of the deadly disease dementia. These literary texts opt for a non-medical approach through which the person suffering dementia is depicted, rather than dementia itself. The family becomes a narrative prism through which to view the changing equations in relationships, the erosion of the family structure, instead of the specific medical condition. In conclusion, one could say that families become the recuperative space for patients rather than medical facilities for long term care. These Indian writers in English do not focus much on the medicalisation of dementia or geriatric health issues. They do mention medical treatments, but the spotlight is on the family, not on clinical viewpoints or medical approaches. Key words: Dementia, disorientation, trauma, deterioration, family space, caregivers.

Does gender influence P300 latency and mini mental state examination score in type 2 diabetes mellitus patients?

Background: P300 event-related potentials (ERPs) is an electrophysiologic marker of cognitive ability which closely reflects cognitive functions. Type 2 Diabetes mellitus (T2DM) causes many complications. Diabetes mellitus-induced damage to the central nervous system is a key focus of research. Latest magnetic resonance imaging evidence suggested that the changes in anatomy of brain is more rapidly seen in males than in females. This study was carried out to study the gender variations in P300 latency and Mini Mental State Examination (MMSE). Aim and Objective: To study the influence of gender on MMSE score as well as P300 ERP. Materials and Methods: 30 diagnosed Type 2 Diabetics aged above 40 years, with more than 2 years duration of diabetes were included in this study. MMSE questionnaire was administered to each diabetic and P300 was recorded using RMS EMG EP MARK 2 machine in all the diabetics. Results: The P300 ERP of male diabetics was prolonged significantly with mean ± standard deviation (SD) of (347.01 ± 31.55) whereas female diabetics had a mean ± SD of (318.26 ± 28.22; P = 0.014) and no significant difference was found between the mean MMSE scores of male diabetics (26.06 ± 1.38) and female diabetics (26.13 ± 1.30). Conclusion: The change in P300 ERP is swifter in males when compared with females in the middle to old age. Compared to MMSE, P300 Latency is a sensitive electrophysiological tool for diagnosing early cognitive deterioration in T2DM.

Enfermedades desmielinizantes: leucodistrofia metacromática y esclerosis múltiple, a propósito de un caso / Demyelinating diseases: metachromatic leukodystrophy and multiple sclerosis, a case study

RESUMEN Las enfermedades desmielinizantes son entidades poco frecuentes en la edad pediátrica; tal es el caso de la esclerosis múltiple y la leucodistrofia metacromática, en las cuales intervienen factores genéticos y ambientales, y ambas afectan diferentes estructuras del sistema nervioso central, los nervios, los músculos, otros órganos y el comportamiento del individuo. Son afecciones que tiene una evolución progresiva al deterioro neuromuscular: en poco tiempo el paciente entra en un estado neurovegetativo con pérdida de la conciencia, por lo que requieren de atención médica y de enfermería especializada. El propósito de este estudio es presentar un caso de leucodistrofia metacromática, haciendo referencia a su complejo diagnóstico diferencial con la esclerosis múltiple y la aplicación del proceso de enfermería. Paciente masculino de 6 años de edad con antecedentes con antecedentes de diversos episodios de infecciones respiratorias y atelectasias, así como estadía prolongada en unidades de cuidados intensivos. Otros síntomas fueron hipotonía muscular, ausencia de reflejos tendinosos y trastornos audiovisuales. A la edad de 6 años el paciente había perdido todo contacto con el medio, sufrió tetraparesia y frecuentes episodios de convulsiones tónicas. A pesar de los intensos tratamientos y seguimientos en diferentes consultas, falleció a los 6 años de edad por complicaciones respiratorias.

ABSTRACT Demyelinating diseases are infrequent entities in pediatric age; such is the case of metachromatic leukodystrophy and multiple sclerosis, in which genetic and environmental factors take action. both of them affect different structures of the central nervous system, nerves, muscles, organs and individual behavior. These affections have a progressive evolution of the neuromuscular deterioration: soon the patient enters a neurovegetative state with loss of consciousness. Therefore, medical attention and specialized nursing is required. The purpose of this study is to present a case of metachromatic leukodystrophy referring to its complex differential diagnosis with multiple sclerosis and nursing process application. A 6-year-old male patient with record of several respiratory infections and atelectasis, such as extended stay at the intensive care unit. Some other symptoms were muscle hypotonia, lack of tendinous reflexes, and audiovisual disorder. At the age of 6 the patient had lost all contact with the environment, suffered from tetra paresis and frequent tonic seizure episodes. Despite the intense treatments and the follow-ups in several medical consultations, the patient passed away at the age of 6 due to respiratory complications.

A Case of Mechanical Hemolytic Anemia due to Aortic Regurgitation Jet Collision with the Mitral Valve Stent-Post / 日本心臓血管外科学会雑誌

The 76-year-old woman underwent double bioprosthetic valve replacement for aortic and mitral valve regurgitation without any postoperative complication. About 33 months later, the patient complained of sudden dyspnea and was diagnosed with mechanical hemolytic anemia, severe aortic regurgitant jet collision with stent post (SP) at mitral position and acute heart failure. The cause of mechanical hemolysis was suspected to be a collision of the regurgitant jet due to structural valve deterioration (SVD) with the SP because of the absence of any paravalvular leak (PVL). The externally-mounted bioprosthetic aortic valve was replaced and the inadequate projection of the SP in left ventricular outflow tract was recognized simultaneously. The patient fully recovered from heart failure and hemolytic anemia after surgery. Early SVD of externally-mounted bioprosthetic valves has often been reported, and the eccentric regurgitant jet due to SVD may collide with any sub-valvular structures. We report a rare case of hemolytic anemia due to SVD.

Physician awareness and attitudes regarding early warning score systems in mainland China: a cross-sectional study

INTRODUCTION@#The purpose of this study was to assess the application of the early warning score system (EWS-S) and gauge physician awareness, perceptions of necessity and attitudes regarding these tools based on previously experienced unnoticed clinical deterioration (CDET).@*METHODS@#A cross-sectional survey was carried out via an online questionnaire at a large 3,500-bed Class 3A general hospital in China. A total of 299 physicians of adult general wards were asked to answer a translated questionnaire that was localised from the original version. Demographic profiles of patients were included as well as three other sections assessing awareness of CDET/EWS-S and gauging attitudes towards and perceptions of the necessity of EWS-S at our hospital.@*RESULTS@#A high level of physician awareness of the CDET problem was observed. Most physicians knew about the existence of a systematic assessment tool for clinical application. Physicians with previous experience in reanimation, unplanned transfer to intensive care unit (UTICU) and/or death tended to consider EWS-S necessary in attentive and well-trained staff (p < 0.05). Physicians who had previous experience with UTICU were more likely to recommend implementing EWS-S in their wards compared with those without such experience (p < 0.05).@*CONCLUSION@#Most physicians have positive attitudes towards EWS-S. However, their awareness should be further heightened. Physicians who had previous experience with CDET/UTICU were more likely to employ EWS-S in their clinical practices. To better facilitate the implementation of EWS-S in Chinese hospitals, existing facilities, policy supports, standardised managements and the development of information systems should be strengthened.

Effect of the national early warning score on monitoring the vital signs of patients in the emergency room / Efecto del national early warning score en el monitoreo de los signos vitales de los pacientes en urgencias / Efeito do national early warning score no monitoramento dos sinais vitais de pacientes no pronto-socorro

ABSTRACT Objective: To verify the effect of using the National Early Warning Score (NEWS) system on the compliance of the vital signs monitoring interval with those recommended for patients in the emergency room. Methods: This is a quasi-experimental, before-and-after study, performed in an emergency room with 280 adult patients selected by convenience. The effect of NEWS on the compliance of the vital signs monitoring interval with those recommended by the system was analyzed by linear regression. Results: In the Pre-NEWS phase, 143 patients were analyzed (mean age ± standard deviation: 54.4 ± 20.5; male: 56.6%) and, in the Post-NEWS phase, 137 patients (mean age ± standard deviation: 55.5 ± 20.8; male: 50.4%). There was compliance of the vital signs monitoring interval with what is recommended by NEWS in 92.6% of vital signs records after adopting this instrument. This compliance was 9% (p < 0.001) higher in the Post-NEWS phase. Conclusion: The use of the NEWS system increased the compliance of the vital signs monitoring intervals with the ones recommended, but this compliance decreased when the NEWS score pointed to a shorter interval in the monitoring of vital signs.
