Authors: Freitas Yuri Borges Bitu de , Lellis Caio de Almeida , Brito Jhenefr Ribeiro , Ramos Rodrigo Souza , Oliveira Maria Luiza Gonzaga de
Published: December 2021

Introduction: Fibromyalgia is a painful syndrome of little known etiology, characterized by generalized pain with difficult management. Thus, cannabis therapy, a therapeutic option for other painful conditions, becomes an alternative. Objective: To review the literature on cannabis therapy in the treatment of fibromyalgia. Design and Setting: A systematic review conducted at the Pontifical Catholic University of Goiás. Methods: Systematic review. Randomized studies and clinical trials published between 01/2011 and 01/2021 were selected. Incomplete studies and those that did not fit the objectives were excluded. Results: When analyzing the combination of inhaled CBD and THC, it was concluded that, regardless of the dosage, neither showed significantly greater response than placebo. Studies pointed out that THC-rich cannabis oil, at starting dose of one drop a day, reduced pain, fatigue, and depression scores; moreover, the therapy proved tolerated and without serious adverse effects. Third-level evidence indicated better effects of nabilone on sleep than amitriptyline, without significant differences for pain, mood, and life quality. Conclusion: Different approaches to cannabis therapy for patients with fibromyalgia lead to diverse effects, with some not proving effective and others promoting pain reduction, sleep and life qualities improvements and satisfactory effects on depression and fatigue scores. Hence, scientifically relevant studies should be done on this subject.

Published: December 2021

Introduction: Cerebrovascular accident (CVA) is the second cause of death in the world, and arterial hypertension (AH) is the main risk factor. Objetives: To evaluate the prevalence of AH and the epidemiological profile of patients who suffered CVA, first and recurrent events, registered at JOINVASC, between 2013 and 2019. Methodology: An observational, descriptive, retrospective study, analyzing demographic data and risk factors, in patients that suffered CVA, first or recurrent event, was done. Results: In the study period, 6057 CVA events were registered, 4402(72.6%) patients were classified as hypertensive, (122 were excluded due to incomplete data), 4387 registers were analyzed. In this group, 2149 (51.2%) were male, mean age was 68.4±14.7(18 a 102 years), BMI was 27.5±5.1(14 a 59), 4330(39.9%) with Diabetes, 2559(58.8%) were smokers or ex-smokers, 3174(7.42%) were sedentary, and 504(11.5%) had controlled AH. In the group with recurrent event (1392-31.7%) (52.3%, p<0.001) were females, mean age was (69.4± 11.5) (p<0.002); BMI was lower (p=0.02). There was more cardiopathy (47.6%) (p<0,001) ,smokers or ex-smokers (66.2)(p<.005), diabetes (46.7%) (p<0.001) and deaths (32.3%)(p<0.001), less physical activity (22.0%)(p<0.001), use of antihypertensive drugs was greater (1.52±0,93)(p<0.001),. Logistic regression showed that female sex, BMI, DM, cardiopathy, physical activity, and more anti- hypertension drugs, were significant predictors for recurrence of neurologic event. Discussion: Despite advances in primary health care and prevention campaigns, the prevalence of AH in patients with CVA is high, and still has low levels of control, even in patients with recurrent CVA.

Authors: Vieira Marcella Beghini Mendes , Lin Jaime
Published: December 2021

Introduction: Renal failure is characterized by functional loss of the kidney and hemodialysis is the therapeutic option. The renal patient may have sleep disorders, including restless legs syndrome (RLS), which occurs in 30% of renal patients and in 10% of the general population. It is a motor neurological disorder, whose etiopathogenesis is not understood. Clinical diagnosis is the gold standard. RLS has been associated with cardiovascular morbities and increased mortality, however, it is underdiagnosed. The present study aimed to assess the prevalence and factors associated with RLS symptoms in patients with dialysis renal failure in a private clinic for chronic renal patients. Methods: Cross-sectional study, including 140 patients seen at the Tubarão Renal Diseases Clinic, from August to November 2016. Results: The average age of the interviewed population was 60.82 years, the majority being men (63.6%). Most respondents reported having restful sleep (78.6%). Despite this, snoring / sleep apnea prevalence was found in more than half of the patients (57.1%) and SPI in 19.3% (the most severe form being found in 8.6% of the patients). Other comorbidities found were: SAH, insomnia, diabetes mellitus and cardiac disorders. Statistically, dialysis time was longer among patients with RLS (P = 0.03). The female gender was shown to be a risk factor (P = 0.006) and cardiac alterations also had a significant association (P = 0.044-Fisher), as well as insomnia (p = 0.00011). Conclusions: Sleep disorders are prevalent and should be part of the assessment of all dialysis patients.

Published: December 2021

Background: In Amyotrophic Lateral Sclerosis (ALS), falls can have negative impacts on activity, participation and quality of life, which include injuries, dependence and mortality. Objectives: To investigate falls in individuals with ALS and and identify potential predictors. Methods: Observational study, in which were included individuals over 18 years old with ALS followed up at the Neuromuscular Diseases Clinic of UFMG. Individuals who were bedridden or had any other neurological disorders were excluded. Capacity/ independence, strength, mobility/performance and ability to walk were evaluated through ALSFRS-R, MRC, TUG and SBBP, respectively. If the participants were able to walk with or without assistance, they were classified as walkers. Falls were investigated considering the last 6 months and ≥ 2 episodes was classified as recurrent. In the logistic regression model, variables with p <0.20 were included in the univariate analysis with a significance level of 0.05. Results: The study included 68 individuals. Of these, 73.5% reported at least one fall in the last 6 months. Among the fallers, 66% were able to walk. Fall recurrence was frequent in walkers (69.7%). When investigating falls in the walking group, only sit and stand test was related to falls. Each worsening of the time in the test, increased the chance of falling by 1.3 times. Conclusions: Sit and stand test was a predictor of falls in walkers with ALS. Knowledge of the characteristics and associated factors is important to identify individuals at risk of falls and to develop protocols.

Authors: Carvalho Isabella Delfim de , Baracat Felipe Iankelevich , Lima Lucas Farina
Published: December 2021

Introduction: Myasthenia Gravis (MG) is an autoimmune and neuromuscular disease. The treatment of immunomodulation consists of intravenous immunoglobulin (IVIg), immunoadsorption (IA), plasmapheresis (PLEX) or double filtration plasmapheresis (DFPP). This systematic review aims to compare therapy modalities in MG crisis. Methods: The studies were identified through research in electronic databases and analyzed individually to clarify their methodological quality (through the Jadad and Newcastle Ottawa scale). Clinical trials randomized or not, and retrospective studies were included. The review included 1,983 patients in nine studies, the result analysis groups were divided into: IVIg x PLEX in the crises; IVIg x PLEX in the pre-thymectomy treatment phase and IVIg x DFPP in the myasthenic crisis. The evaluated outcomes were clinical improvement, adverse effects and length of hospital stay. Results: Immunomodulatory therapy when applied prior to thymectomy was shown to be effective in reducing symptoms and post-thymectomy hospitalization, with IVIg slightly higher, while PLEX showed more side effects. Therapy during crises in both interventions proved to be effective after the 14th start of treatment, in addition to IVIg being slightly superior. Treatment with IVIg was also economically favorable, due to the lower need for hospitalizations. IVIg proved to be inferior to therapy with DFPP and IA, mainly in reducing the need for hospitalization. Conclusion: It is concluded that IVIg therapy is a good therapeutic option in cases of crisis and when available, therapies with DFPP and IA should be the choices, aiming at less complications.

Published: December 2021

Context: Downbeat nystagmus are characterized by the rapid phase in the down direction in primary position of the eyes, in the most cases represents a cerebellar dysfunction, typically with injuries involving vestibulocerebellum (flocculus, paraflocculus, nodule and uvula), although most cases are due to primary lesions in the brain stem, usually involving paramedian tracts. This type of nystagmus is characteristic of craniocervical abnormalities, such as Chiari 1 malformation, also being seen in a wide variety of cerebellar diseases, including degenerative etiologies, toxic-metabolic and ischemic injury. Case report: A 45-year-old woman, who presented with dizziness started 6 years ago, related to rapid head movement, with progressive worsening, leading to difficulty in walking and a tendency to fall to the right, associated with mild to moderate intensity occipitonuchal headache, with improvement at rest and horizontal decubitus. Neurological examination showed downbeat nystagmus, intent tremor in the finger-to-nose-test, worse on the right arm, Romberg test presentes with anteroposterior and lateral instability, in addition to Tanden with bilateral lateropulsion, without other relevant changes. The magnetic resonance imaging showed platybasia and vertebrobasilar invagination, Chiari type 1 malformation with tonsillar herniation, without signs of cervical hydrosyringomyelia, signs of atrophy of both cerebellar hemispheres, a nonspecific nodule in the subcortical region of the left precuncle. Conclusion: The case described above is relevant to demonstrate that even in cases of acute changes in adulthood, screening for anatomical malformations in the posterior fossa should be considered.

Published: December 2021

Background: Hypertension is a medical condition that often occurs parallel to diabetes and obesity. Previously, the role of fat mass and obesity associated (FTO) gene rs9939609 polymorphism (c.46-23525T>A) with obesity has been reported while prevalence and etiological differences exist among different regions and ethnic groups. Aim: To investigate the association of FTO rs9939609 SNP with hypertension in Pakistani population. Study design: Cross-sectional study. Place and duration of study: Institute of Biomedical and Genetic Engineering (IBGE), Islamabad, Pakistan from 1st January 2019 to 31st December 2020. Methodology: One hundred and ten diagnosed hypertension patients along with 128 healthy volunteers were selected randomly. The single nucleotide polymorphism was analyzed using Amplified Refractory Mutation System-Polymerase Chain Reaction. Results: In hypertension patients, females were found to be relatively more affected and average blood pressure lies in stage 1. However, we found no significant difference in genotypic frequencies of FTO rs9939609; TT (22.6%), AA (39.6%) and AT (37.8%) and TT (17.18%), AA (39.06%), and AT (43.75%) among HT and controls, respectively. The p and OR values for risk type genotype (AA) are 0.4697 and 0.7700 (95% CI=0.3788-1.565), respectively. Subsequently, the high percentage (60.0 %) of risk genotype (AA) was found in obese-body mass index in hypertension patients. Conclusion: FTO rs9939609 single nucleotide polymorphism may not be a genetic risk factor associated with onset of hypertension directly and is linked with obesity in Pakistani patients. Keywords: FTO, Hypertension, Obesity, Pakistani patients, rs9939609

Reflexiones en torno al Chile pospinochet: la memoria, el miedo y la didáctica de la historia
Authors: Aceituno Silva David
Published: December 2021

La Transición chilena ha sido valorada internacionalmente por ser un modelo de cambio pacífico y consensuado desde la Dictadura a la Democracia. Esto ha sido reafirmado especialmente por la bibliografía politológica. Sin embargo, el énfasis puesto en los cambios positivos vividos durante la Transición oculta acontecimientos que muestran un Chile con permanencias menos alegres.

En este sentido, la Memoria conformada durante los años 90 fue “cautivada” por los discursos políticos que, con el fin de reconstruir un consenso social, terminó por elegir el olvido por sobre el recuerdo y el acuerdo intra-elitario, por sobre el re-encuentro de la sociedad. Intentaremos en este artículo de-construir y re-construir los discursos acerca de la Transición y dar una mirada diferente al tan “exitoso” periodo. En las siguientes líneas hacemos una pequeña reflexión histórica y didáctica útil para seguir pensando en una ciudadanía sana, activa y consciente del pasado, sin opresiones o falsedades.
Reflexiones acerca de la conformación de la identidad y la memoria desde el patrimonio
Authors: González Yesica Mariana
Published: December 2021

Las luchas por la apropiación y la resignificación del pasado se dan a través de los procesos de patrimonialización. Éstos suele ser llevados cabo por distintos grupos dentro de la sociedad, pero finalmente la “activación” queda en manos de aquellos que cuentan con el poder suficiente para hacerlo. Desde esta perspectiva, la construcción de la memoria, y su anclaje a través de referentes tangibles e intangibles, se constituye en un campo de lucha y de poder. El propósito de este artículo es, entonces, repensar los procesos y factores que inciden en la patrimonialización y su anclaje en la memoria.
¿Cómo interpretan las estudiantes de maestra de educación infantil el término socialización? La Socialización y la Enseñanza de las Ciencias Sociales en la Formación Profesional Inicial
Authors: Hernández Cervantes Lorenia
Published: December 2021

El siguiente artículo analiza las representaciones sociales de un grupo de 12 estudiantes de maestra de educación infantil sobre el término socialización y su relación con la enseñanza de las ciencias sociales. El término socialización es analizado a partir de tres paradigmas: funcionalista, interpretativo y crítico (Zeichner & Gore, 1990) y a partir de la Didáctica de las Ciencias Sociales (Pagès, 1997, Pagès & Santisteban, 2011). Los resultados muestran que el termino socialización es interpretado por las estudiantes a partir del paradigma funcionalista. Su relación con la enseñanza de las ciencias sociales en la educación infantil está vinculada con la enseñanza de reglas, normas de convivencia y los festejos patrios.

Crop growth simulation models, properly validated against experimental data have the potential for facilitating strategic decision making in agriculture. Such validated models can also make use of the information generated for site specific experiments and trials to other sites and for different time durations. For proper calibration and evaluation of crop simulation models, there is a need for collection of a comprehensive minimum set of data on soil, weather and crop management in all agronomic experiments. Keeping this in view, data from seven field experiments conducted at Jorhat (26° 47' N, 94°12' E; 87 m amsl) during 1998-2005 for long duration rice cultivar Ranjit grown under rainfed conditions were collected. Genetic coefficients required for running the CERES-Rice v4.5 model were derived and the performance of the model under the climate of upper Brahmaputra valley was evaluated. These results indicate that the CERES Rice v4.5 model is capable of estimating growth stages and grain yield of rice cultivar Ranjit in the climatic conditions of upper Brahmaputra valley with reasonable accuracy. Hence, the model have the potential for its use as a tool in making various strategic and tactical decisions related to agricultural planning in the state.

Accurate precipitation in mountain area is very important for evaluating the hydrological process and ecological problem. With the satellite data having been widely used in the past few decades, adaptability evaluation becomes the principle problem. The adaptability of TRMM 3B43 in mountain area of Central Asia was analyzed in this study. The TRMM product was compared with the observed data for the period of 2000-2006. Four statistic parameters were introduced based on the statistical analysis theory. The results show that the bias reached -13.93% over the entire regions, and the correlation coefficients over 70% of stations were greater than 0.70. According to the accuracy analysis of TRMM, we found the errors have significant differences in time and space. On the whole, the precision in the warm seasons is much higher than that in the cold seasons. The precision of the southern and eastern areas is higher than the other areas in space. Additionally, the accuracy of TRMM with elevation was acceptable at very significant level. This study indicates that the precipitation from TRMM 3B43 could be applied in the Tianshan Mountains in Central Asia. It could provide reference for the use of new data source in the mountain area.

Amongst all the climatic elements, temperature plays a major role in detecting and analyzing climatic change and its impact. The variability in resident time of the surface temperature is studied to investigate whether any change in temperature has taken place. Analysis of the results is presented for Mumbai, a mega city with large change in land-use pattern, Thiruvananthapuram, a semi-urban city with moderate changes in land-use pattern and Minicoy, an Island city without much change in land-use pattern. These three places representing varying geographical locations and climatic conditions are unique in nature, however having uniform maritime influence. It is revealed that the change is large in Mumbai in comparison with others as expected. The study proposes a new methodology based on the resident time of temperatures and its trend and could be used as a tool for relative ranking of cities and to gauge the source and sink regions of climate change forcing. The resident time of temperatures shows increasing trend above the mean temperature and decreasing trend below the mean temperature of the initial decade. Decadal linear increasing trends in mean temperatures are 0.256 °C, 0.159 °C and 0.146 °C per decade for Mumbai, Thiruvananthapuram and Minicoy respectively. This confirms the effect of global warming unequivocally irrespective of urban effect. Decadal linear increasing trends in mean temperature during non-monsoon season for Mumbai, Thiruvananthapuram and Minicoy are 0.315 °C, 0.155 °C and 0.181 °C per decade respectively. The rate of increase of mean temperature for Mumbai and Minicoy during monsoon season is 0.143 °C and 0.081 °C per decade respectively, are significantly less than the decadal trend in annual mean, which suggests that rainfall activity seems to be the correction factor for the increasing trend in the annual mean temperature which otherwise would have been a higher value. However, the rate of increase of mean temperature for Thiruvananthapuram during monsoon season for the study period is 0.172 °C per decade, which is slightly higher than the decadal trend in annual mean. Noticeable changes in resident time during monsoon season are in conformity with change in rainfall patterns.

Published: December 2021

The method of eigen function expansion has been used in the present study to compute synthetic or theoretical seismogram in layered elastic half-space of real earth model. Simple dislocation source model has been considered. The transverse (SH) or radial and vertical (P-SV) components of displacement field have been computed as summed modes and compared by using both exact and numerical techniques. The methods used in the study, include exact evaluation by propagator matrix approach using Reflection-Transmission coefficients as well as numerical computations using Runge-Kutta method of order 4. The specialty of the present study is to evaluate approximate displacement field for the earth models with homogeneous and / or inhomogeneous layers. The normalization technique has been used in the study to control the overflow errors. The study has an advantage to get an idea of earth structure or source model by an inverse iterative technique.
Clustering technique for interpretation of cloudburst over Uttarakhand

Published: December 2021

Data Mining has been used extensively in various business and scientific applications for last few years. Data mining has been found to be providing a deep insight into understanding the hidden facts in huge databases. Data mining is an interdisciplinary subfield of computer science that discovers patterns in large data sets by using methods at the intersection of artificial intelligence, machine learning, statistics, and database systems. In this paper, data mining technique for Interpretation of Weather Forecasts for one of the most disastrous weather phenomenon viz. cloudburst has been applied. Every year, cloudburst over hilly areas and coastal regions causes loss of lives and property. The forecasting and warning of these events is very difficult. There is no satisfactory technique for anticipating the occurrence of cloudbursts because of their small scale. A very fine network of radars is required to be able to detect the likelihood of a cloudburst and this would be prohibitively expensive. The warning of cloudburst could only be provided at a small lead time say a few hours in advance based on the interpretation of latest satellite imagery data, powerful radar (Doppler category), if available, or by using Model Output Statistics (MOS) models. Another dimension to forecasting this weather event has been identified by applying clustering technique on primary data forecasted by global and regional models of weather forecasting. A recent case of Cloudburst over Uttarakhand that caused a huge loss has been analyzed using k-means clustering technique of data mining. It has been observed that with the mining of Numerical Weather Prediction model forecast data, the signals of formation of cloudburst can be found3-4 days in advance.

Published: December 2021

Summer monsoon onset progress from the oceanic region of Southeast Bay of Bengal / Andaman Sea (Oceanr) up to extreme southwestern part of India (Kerala) for the years 2009 to 2014 is investigated. Synoptic weather information, INSAT/KALPANA-1 as well as cloud imageries archived from Dundee Satellite Receiving Station for May and early June for these years are used in the analysis. Upper-air reanalyzed winds from NCEP/NCAR and OLR data archived through NOAA satellites are also used. During the study period, the dates of monsoon onset as well as the time required for the advancement of onset from Oceanr to Kerala have shown a large variation. An attempt is made to investigate the causes for such variations. The results indicate that intense disturbances which formed over north Indian Ocean in 2009, 2010, 2013 and 2014 and over west-north Pacific Oceanic region in 2011 and 2012 have contributed for the same. Analysis is carried out, limiting its focus to bring out the role of these convective events in the observed variation of onset timing and its progress by taking case to case review of these events and bringing out their influence through synoptic analysis. Utility of this information in prediction of the progress of Indian summer monsoon onset is also brought out.

IMD started issuing quantitative district level weather forecast upto 5 days on operational basis from 1st June, 2008. The products comprise of quantitative forecasts for seven weather parameters, viz., rainfall, maximum and minimum temperatures, wind speed and direction, relative humidity and cloudiness. The rainfall forecast is generated  based on multi model-ensemble techniques (MME). For other parameters, ECMWF forecasts (presently IMDGFS) are used. These forecast products are further value added, by the respective MCs/RMCs and forwarded to 130 Agrometeorological Field Units (AMFUs) for preparation of weather based District Agromet Advisory Service bulletin.  This Meteorological Monograph describes the performance skill of the operational district level weather forecasts over different parts of India rainfall during monsoon and temperature during winter and summer from 2012-14.  The Monograph also highlights limitations and future scope for further improvement of the MME models. The   verification results show weather forecasts are reasonably accurate and value addition has improved the accuracy of model forecast. Though the MME model could predict the weather in hill regions in the North but in other regions having some hilly areas, the same could not come true in respect of temperature.  North East region of the country shows very less accuracy due to its predominantly humid sub-tropical climate with hot, humid summers, severe monsoons and mild winter.

An attempt has been made to detect the pattern of rainfall and examine the trends and variations of extreme events of rainfall over Varanasi (Uttar Pradesh, India) through seasonal, monthly and decadal analysis during southwest monsoon season (June-September) using the daily rainfall data of 40 years period from 1971-2010. The results show that cumulative rainfall during 1971-2010 is overall decreasing in monsoon season as well as in all the months June, July, August and September. In general, the observed rainfall events in all categories (Non rainy day, 0-2.4 mm; Category I, 2.5-64.4; Category II, 64.5 to 124.4; Category III, 124.5 mm or more) have a decreasing trend in all the months and monsoon season over the entire period of study. However, decadal analysis reveals that in general frequency of rainfall events in almost every category is decreasing in recent decade. Different results are seen in August, as cumulative rainfall is decreasing in this month, whereas very heavy and exceptionally heavy rainfall events and their contribution have increased in recent decade as well as over total period.
