RESUMEN

INTRODUCTION: The rapid advance of Coronavirus disease 2019 (Covid-19) has led to the incessant search for therapeutic and prophylactic measures to fight the pandemic. Because it is a viral infection, the safest long-term prophylactic form, in addition to social distance and hygiene, is the vaccine. OBJECTIVE: Thus, this study aimed at conducting a review of the efficacy and landscape of Covid-19 vaccines. METHODS: The following electronic databases were used MEDLINE via PubMed, SCIELO, LILACS, NEJM, and Clinical Trials. Our study includes the 7 vaccines (phase 3) that reported an efficacy rate for Covid-19, including characteristics inherent to each one of them. RESULTS: Preliminary studies have shown that, although an efficacy ≥70% is necessary to eliminate the infection, a prophylactic vaccine with efficacy <70% will still have an important impact and can contribute to the elimination of the virus, provided that appropriate measures of social distancing remain. CONCLUSIONS: The effectiveness of the vaccines obtained in this study varied between 50.38 and 95%, data that may represent a reduction in serious cases, hospitalizations, sequels, and deaths caused by Covid-19, respecting the panorama presented in this article.

RESUMEN

OBJECTIVE: To conduct a review of articles which have evaluated the relationship between vitamin D and cardioprotection in adult. METHODS: A literature search was performed in the Pubmed and Scielo databases. The results were extracted from primary and secondary sources and will be presented in the form of a bibliographic review. RESULTS: Twenty-three articles were identified from the electronic search that reported on physiological mechanisms relating the vitamin D axis and the cardiovascular system through receptors. Of the ten studies that evaluated the therapeutic effect of vitamin D in cardiovascular diseases, none reported significant results. CONCLUSION: The articles assessed in this review did not demonstrate a cardioprotective effect of vitamin D, despite the epidemiological correlation of vitamin D deficiency with a higher prevalence of cardiovascular diseases.

RESUMEN

The etiological agent of COVID-19, which causes severe respiratory diseases such as pneumonia and pulmonary insufficiency, has been confirmed as a new coronavirus, now known as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). There is currently no authorized medication for the treatment of COVID-19. No vaccines have been authorized. Thus, this study aimed at conducting a review of the use of Remdesivir in patients with COVID-19. The following electronic databases were used MEDLINE, SCIELO, LILACS, and PUBMED. On May 1, Remdesivir received emergency use authorization from the Food and Drug Administration. Remdesivir is currently the most promising molecule in the treatment of COVID-19, taking into account its broad antiviral spectrum (considering the genetic sequences of the virus, it is expected to maintain activity against SARS-CoV-2). There is in vitro and in vivo information available for coronaviruses, as well as an extensive clinical safety database (from a clinical trial of the Ebola virus and in the context of the Monitored Emergency Use of Unregistered and Investigational Interventions - MEURI). Further studies are relevant as available data on the efficacy and safety of Remdesivir against SARS-nCoV-2 are limited.

RESUMEN

The present study aimed to review the epidemiology, clinical manifestation, laboratory diagnosis, treatment, and future perspectives related to COVID-19 infections. The following electronic databases were used searched: MEDLINE, SCIELO, and LILACS. It became clear that COVID-19 infections occur through exposure to the virus, and both the immunosuppressed and healthy population appear susceptible. The clinical course of COVID-19 is still not clear, although the SARS-CoV-2 infection seems to develop with mild, influenza-like symptoms in the vast majority of subjects, i.e., 10%-15% of COVID-19 patients. Since rRT-PCR tests serve as the gold standard method to confirm a SARS-CoV-2 infection, false-negative results could hinder the prevention and control of the epidemic, particularly considering the test plays a key role in the decision for continued isolated medical observation or discharge. Our findings also indicate that a radical increase in the identification and isolation of currently undocumented infections would be needed to fully control SARS-CoV2.

RESUMEN

This systematic review aimed to assess the effectiveness of using preservative-free artificial tears versus preserved lubricants for the treatment of dry eyes in Universidade Federal de Alagoas (PROSPERO 2018 CRD42018089933). Online databases were searched (LILACS, EMBASE, MEDLINE, and CENTRAL) from inception to April 2018; references from included papers were also searched. The following keywords were used: lubricants OR artificial tears OR artificial tears, lubricants AND dry eye OR dry eye syndrome OR syndromes, dry eye OR dry eyes. Among the 2028 electronic search results, 29 full papers were retrieved and four were considered relevant. The number of participants from these studies ranged from 15 to 76. Meta-analysis was possible for the following outcomes: score of symptoms according to the Ocular Surface Disease Index - Allergan (OSDI), tear secretion rate using the Schirmer test, tear evaporation rate using the tear film breakup time test, burning, foreign body sensation, and photophobia. No statistically significant difference was observed between the two groups, and no side effects were attributed to the interventions. Evidence proving that preservative-free artificial tears are more effective than preserved artificial tears is lacking.

RESUMEN

BACKGROUND AND OBJECTIVES: Low back pain is a prevalent disease in the adult population, whose quality of life is considerably affected. In order to solve this problem, several therapies have been developed, of which ozone therapy is an example. Our objective in this study was to determine the effectiveness of ozone therapy for lumbar pain relief in adult patients compared to other therapies (steroid and placebo). METHOD: We used randomized clinical trials to compare the effectiveness of ozone and other therapies for lumbar pain relief in adults (Prospero: CRD42018090807). Two independent reviewers searched the Medline (1966-April/2018), Scopus (2011-May/2018), Lilacs (1982-May/2018), and Embase (1974-March/2018) databases. We use the terms ozone and pain as descriptors. The primary variable was pain relief and the secondary ones were complication, degree of satisfaction, quality of life, and recurrence of pain. RESULTS: Of the 779 identified articles, six selected clinical trials show that ozone therapy is more effective for lumbar pain relief; however, they were mostly classified as having a high or uncertain risk of bias (Cochrane Handbook). The meta-analysis regarding the effectiveness of pain relief did not show a significant difference between groups in the three-month period (RR = 1.98, 95% CI: 0.46-8.42, p = 0.36; 366 participants). It also showed greater effectiveness of the ozone therapy at six months compared to other therapies (steroid and placebo) (RR = 2.2, 95% CI: 1.87-2.60, p < 0.00001; 717 participants). CONCLUSIONS: The systematic review has shown that ozone therapy used for six months for lumbar pain relief is more effective than other therapies; however, this result is not definitive as data from studies with moderate to high risk of bias were used.

RESUMEN

BACKGROUND AND OBJECTIVE: The systematic review of randomized clinical trials is crucial to assess the safety and effectiveness of intermediate procedures. The objective of this article is to present a tutorial for the planning and execution of systematic review and meta-analysis of randomized clinical trial studies. CONTENT: The systematic literature review is the type of research that organizes, criticizes, and integrates available evidence published in the health field. Systematization leads to less bias, however, the quality of systematic reviews may not always be perceived due to the way it is described in the articles. The information disclosed in the articles is not always free of bias. The steps for carrying out a systematic review include design, protocol registration, implementation, mathematical analysis of results, and dissemination. PRISMA statement has improved the quality of systematic review reports by providing a list of items to be described, and this article emphasizes the key steps for performing a systematic review of interventions. CONCLUSION: The evidence generated through a systematic review can provide the clinician with greater confidence in decision making at the moment of clinical practice and optimize the benefits to his patients, serving as a tool to assist managers in making decisions regarding the implementation of new strategies in favor of the public health.

RESUMEN

INTRODUCTION: Diabetes mellitus is one of the most common chronic diseases in the world, with high morbidity and mortality rates, resulting in a greatly negative socioeconomic impact. Although there are several classes of oral antidiabetic agents, most of the patients are outside the therapeutic goal range. OBJECTIVE: To review the use of SGLT-2 inhibitors in the treatment of type 2 diabetes mellitus, focusing on their favorable and unfavorable effects, as well as on cardiovascular profile. METHOD: A literature search on Pubmed database was performed using the following keywords: "SGLT-2 inhibitors," "dapagliflozin," "empagliflozin," "canagliflozin." RESULTS: SGLT-2 inhibitors are a class of oral antidiabetic drugs directed to the kidney. Their mechanism of action is to reduce blood glucose by inducing glycosuria. Extra-glycemic benefits have been described, such as weight loss, decline in blood pressure and levels of triglycerides and uric acid, and they can slow the progression of kidney disease. Genitourinary infections are the main side effects. There is a low risk of hypotension and hypoglycemia. Diabetic ketoacidosis is a serious adverse effect, although rare. Empagliflozin has already had its cardiovascular benefit demonstrated and studies with other drugs are currently being performed. CONCLUSION: SGLT-2 inhibitors are a new treatment option for type 2 diabetes mellitus, acting independently of insulin. They have potential benefits other than the reduction of blood glucose, but also carry a risk for adverse effects.

RESUMEN

OBJECTIVE:: Determine whether there is an association between the risk of cardiovascular adverse events and the use of antipsychotic agents. METHOD:: Analysis of original articles retrieved from the following databases: LILACS, PubMed, Cochrane Controlled Trials Clinical Data Bank (CENTRAL) and PsycINFO, without language restriction, dated until November 2015. After screening of 2,812 studies, three cohort original articles were selected for quality analysis. RESULTS:: 403,083 patients with schizophrenia and 119,015 participants in the control group data were analyzed. The occurrence of cardiovascular events observed in the articles was: 63.5% (article 1), 13.1% (article 2) and 24.95% (article 3) in the group of treated schizophrenic patients, and 46.2%, 86.9% and 24.9%, respectively, in the control groups. CONCLUSION:: Clinical heterogeneity among the studies led to a provisional response and made it impossible to perform the meta-analysis, although the articles demonstrate an association between cardiovascular adverse events and the use of antipsychotics. More quality clinical trials are needed to support this evidence.

RESUMEN

OBJECTIVE:: To determine the diagnostic accuracy of ultrasound to detect deep--vein thrombosis in pregnant patients. METHOD:: We searched Pubmed, LILACS, Scopus, Google Scholar and System for Information on Grey Literature from inception to April 2016. The reference lists of the included studies were analyzed. Original articles from accuracy studies that analyzed ultrasonography to diagnose deep-vein thrombosis in pregnant women were included. Reference standard was the follow-up time. The QUADAS-2 score was used for quality assessment. RESULTS:: Titles and summaries from 2,129 articles were identified. Four studies that evaluated deep-vein thrombosis in pregnant women were included. In all, 486 participants were enrolled. High risk of bias was seen in three out of four studies included regarding flow and timing domain of QUADAS-2. Negative predictive value was 99.39%. CONCLUSION:: Accuracy of ultrasonography to diagnose deep-vein thrombosis in pregnant women was not determined due to the absence of data yielding positive results. Further studies of low risk of bias are needed to determine the diagnostic accuracy of ultrasonography in this clinical scenario.

RESUMEN

SUMMARY: The lateral pterygoid muscle (LPM) is intimately related with the temporomandibular joint (TMJ), playing an important role in its physiology. This makes it of interest to researchers who investigate temporomandibular disorders. The literature indicates that anatomical variations exist in the insertion of the superior fascicle of the LPM. Imaging and cadaver studies have revealed that the LPM may present an accessory fascicle. The study object was to carry out macroscopic analysis of the LPM, examining the origin and insertion of its superior and inferior fascicles. The study used 38 half-heads of adult individuals fixed in formaldehyde 10 %. To carry out macroscopic analysis of the LPM, an initial incision was made along the lower margin of the zygomatic arch; the origin of the masseter muscle was then dissected, separating its insertion on the lateral face of the mandibular ramus and retracting the muscle to posteroinferior. Two incisions were made on the zygomatic arch and the insertion of the temporal muscle on the coronoid process was identified with dissection pincers; it was dissected to gain access to the infratemporal fossa and the two fascicles of the LPM. The superior fascicle (SF) originated on the infratemporal face of the greater wing of the sphenoid, and on the superior third of the lateral face of the lateral lamina of the pterygoid process of the sphenoid in 26 samples. In 12 samples, it originated on the greater wing of the sphenoid and the infratemporal crest of the sphenoid. Type I insertion was found in 20 samples, Type II in 6 samples and Type III in 12 samples. In all the samples analysed, the inferior fascicle (IF) originated on the inferior two thirds of the lateral face of the lateral lamina of the pterygoid process and on the lateral face of the pyramidal process of the palatine, with insertion on the pterygoid fovea. The accessory fascicle (AF) of the LPM was present in 6 samples. The AF originated on the greater wing of the sphenoid in 2 cases and inferior to the superior fascicle in 4 cases; its insertion was on the capsular disc complex in all cases. The results obtained in our study contribute anatomical data on the LPM in Brazilian adult individuals, with evaluation of its insertion points.


El músculo pterigoideo lateral (MPL) presenta íntima relación con la articulación temporomandibular (ATM) y desempeña un rol importante en la fisiología de esta articulación, despertando el interés de investigadores que se dedican al estudio de los trastornos temporomandibulares. La literatura señala que existen variaciones anatómicas del MPL, con respecto a la inserción del fascículo superior. Los estudios cadavéricos e imagenológicos han revelado que el MPL puede presentar un fascículo accesorio. El objetivo del estudio fue realizar un análisis macroscópico del MPL, examinando el origen e inserción de sus fascículos superior e inferior. Se utilizaron 38 hemicabezas de individuos adultos fijadas en formaldehído al 10 %. Para realizar el análisis macroscópico del MPL se realizó inicialmente una incisión a lo largo del margen inferior del arco cigomático, luego se seccionó el origen del músculo masétero separando su inserción en la cara lateral de la rama de la mandíbula, retrayendo al músculo en sentido posteroinferior. Se hicieron dos cortes en el arco cigomático y con pinzas de disección se identificó la inserción del músculo temporal en el proceso coronoides, el cual se seccionó para ingresar a la fosa infratemporal y acceder a ambos fascículos del MPL. El fascículo superior (FS) del MPL se originó en la cara infratemporal del ala mayor del esfenoides y en el tercio superior de la cara lateral de la lámina lateral del proceso pterigoides del esfenoides en 26 muestras. En 12 muestras se originó en el ala mayor del esfenoides y cresta infratemporal del esfenoides. Con relación a su inserción, se encontró el Tipo I en 20 muestras; el Tipo II en 6 muestras y el Tipo III en 12 muestras. En todas las muestras analizadas el origen del fascículo inferior (FI) del MPL fue en los dos tercios inferiores de la cara lateral de la lámina lateral del proceso pterigoides y en la cara lateral del proceso piramidal del palatino insertándose en la fóvea pterigoidea. El fascículo accesorio (FA) del MPL estuvo presente en 6 muestras. El FA se originó en el ala mayor del esfenoides en 2 casos e inferior al fascículo superior en 4 casos y su inserción, en el complejo disco capsular en todos los casos. Mediante los resultados obtenidos en nuestro estudio estamos aportando datos anatómicos en relación al MPL en individuos brasileños adultos, evaluándolo con respecto a sus lugares de inserción.

RESUMEN

BACKGROUND AND OBJECTIVE: The current jobs are insufficient to determine the causative agent, as well as to identify characteristic high risk profiles for BS, leaving a clear need for more studies to this end. This study objective was to evaluate the correlation between weekly workload and BS dimensions. METHODS: An observational, descriptive, cross-sectional study performed with 43 anesthesiologists from Maceió-AL, with the application of Maslach Burnout Inventory (MBI) forms. Pearson's correlation coefficient r was used for the three dimensions and a 95% confidence interval for the prevalence of burnout syndrome and high scores in all three dimensions. RESULTS: Among the studied physicians, 51.16% were male and the average age was 49.82±12.05 years. For physicians who have been diagnosed with BS through the MBI, the average weekly working time 69.27±22.39h. The high level of frequency in at least one of the three dimensions was found in 67.44% of physicians, with this percentage being considered diagnostic for burnout syndrome in this population. CONCLUSION: This study showed no correlation between the weekly working time and the BS dimensions in this population.

RESUMEN

SUMMARY: The lateral pterygoid muscle (LPM) is one of the muscles involved in jaw movements, and is therefore of great importance in the physiology of the temporomandibular joint. This muscle has classically been considered to have two heads, superior and inferior, however previous studies have indicated the presence of a third head (TH). The object of this research was therefore to evaluate, through a study in cadavers, the presence of the third head of the LPM and its relation with the joint disc of the TMJ in adult individuals. The study used 30 half-skulls of adult individuals, 11 right side and 19 left side. The number of heads on each LPM was analysed, with the length and thickness of each. The Chi-squared, Mann-Whitney U, Kruskall-Wallis and Spearman's correlation coefficient tests were applied, with a significance threshold of 5 %. The TH of the LPM was present in 20 % of the samples. Statistically significant differences were found in the thickness of the superior head (SH) vs. the inferior head (IH) (p<0.001) and between TH vs. SH and TH vs. IH (p=0.010). No correlation was found between the thickness of the heads or in their lengths. The LPM most frequently presents two heads, superior and inferior. The TH is an anatomical variation that may be present in 20 % of cases. The IH usually presents the greatest thickness. The use of cadavers is a good method for analysing the presence of the TH and the morphometry of the various heads of the LPM.


RESUMEN: El músculo pterigoideo lateral (MPL) es uno de los músculos involucrados en los movimientos mandibulares y por consiguiente tiene una gran importancia en la fisiología de la articulación temporomandibular (ATM). Clásicamente se ha considerado como un músculo que presenta dos cabezas, una superior y otra inferior, sin embargo estudios anteriores han señalado la presencia de una tercera cabeza (TC). El objetivo fue evaluar, mediante estudio en cadáveres, la presencia de la tercera cabeza del MPL y su relación con el disco articular de la ATM de individuos adultos. Se utilizaron 30 hemicabezas de individuos adultos, 11 del lado derecho y 19 en el lado izquierdo. Se analizó el número de cabezas, longitud y grosor de cada cabeza. Se aplicaron las pruebas de chi-cuadrado, U-Mann-Whitney, Kruskall-Walis y coeficiente de correlación de Spearman, con umbral de significación de 5 %. La TC del MPL estuvo presente en 20 % de las muestras. Se encontraron diferencias estadísticas significativas para el grosor del la cabeza superior (CS) vs. cabeza inferior (CI) (p<0,001) y entre TC vs. CS y TC vs. CI (p=0,010). No se encontró correlación entre el grosor de las cabezas o para la longitud de las cabezas. El MPL se presenta más frecuentemente con dos cabezas, una superior y otra inferior. La TC es una variación anatómica que puede estar presente en un 20 % de los casos. La CI suele ser la que presenta mayor grosor. En cuanto a los métodos para análisis de presencia de la TC y morfometría de las distintas cabezas del MPL el uso de cadáveres representa una buena alternativa.

RESUMEN

BACKGROUND AND OBJECTIVES: Recently, administration of sciatic nerve block has been revised due to the potential benefit for postoperative analgesia and patient satisfaction after the advent of ultrasound. The aim of this study was to describe the anatomical relations of the sciatic nerve in the popliteal fossa to determine the optimal distance the needle must be positioned in order to realize the sciatic nerve block anterior to its bifurcation into the tibial and common fibular nerve. METHOD: The study was conducted by dissection of human cadavers' popliteal fossa, fixed in 10% formalin, from the Laboratory of Human Anatomy and Morphology Departments of the Universidade Federal de Alagoas and Universidade de Ciências da Saúde de Alagoas. Access to the sciatic nerve was obtained. RESULTS: 44 popliteal fossa were analyzed. The bifurcation of the sciatic nerve in relation to the apex of the fossa was observed. There was bifurcation in: 67.96% below the apex, 15.90% above the apex, 11.36% near the apex, and 4.78% in the gluteal region. CONCLUSIONS: The sciatic nerve bifurcation to its branches occurs at various levels, and the chance to succeed when the needle is placed between 5 and 7 cm above the popliteal is 95.22%.

RESUMEN

A systematic review was conducted to investigate the relationship between visual impairment and depression in the elderly. We searched electronic databases (LILACS, SciELO, MEDLINE, and Cochrane Central Register of Controlled Trials) from inception to August 2014 and researched the described references. The search strategy used the following terms: (visual impairment or blindness) and (elderly) and (depression). Of the 641 electronics, 42 works were selected in full and another 20 were identified as being possibly relevant. Ten studies were included. The studies ranged in sample size from 31 to 21,995 participants. Depression was associated with visual impairment in all studies; however, without standardization of diagnostic tests, we could not conduct a meta-analysis or establish a relationship between visual impairment and depression in the elderly.

RESUMEN

SUMMARY OBJECTIVE: To conduct a review of articles which have evaluated the relationship between vitamin D and cardioprotection in adult. METHODS: A literature search was performed in the Pubmed and Scielo databases. The results were extracted from primary and secondary sources and will be presented in the form of a bibliographic review. RESULTS: Twenty-three articles were identified from the electronic search that reported on physiological mechanisms relating the vitamin D axis and the cardiovascular system through receptors. Of the ten studies that evaluated the therapeutic effect of vitamin D in cardiovascular diseases, none reported significant results. CONCLUSION: The articles assessed in this review did not demonstrate a cardioprotective effect of vitamin D, despite the epidemiological correlation of vitamin D deficiency with a higher prevalence of cardiovascular diseases.

RESUMEN

SUMMARY The etiological agent of COVID-19, which causes severe respiratory diseases such as pneumonia and pulmonary insufficiency, has been confirmed as a new coronavirus, now known as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). There is currently no authorized medication for the treatment of COVID-19. No vaccines have been authorized. Thus, this study aimed at conducting a review of the use of Remdesivir in patients with COVID-19. The following electronic databases were used MEDLINE, SCIELO, LILACS, and PUBMED. On May 1, Remdesivir received emergency use authorization from the Food and Drug Administration. Remdesivir is currently the most promising molecule in the treatment of COVID-19, taking into account its broad antiviral spectrum (considering the genetic sequences of the virus, it is expected to maintain activity against SARS-CoV-2). There is in vitro and in vivo information available for coronaviruses, as well as an extensive clinical safety database (from a clinical trial of the Ebola virus and in the context of the Monitored Emergency Use of Unregistered and Investigational Interventions - MEURI). Further studies are relevant as available data on the efficacy and safety of Remdesivir against SARS-nCoV-2 are limited.


RESUMO O agente etiológico da COVID-19, que causa doenças respiratórias graves, como pneumonia e insuficiência pulmonar, foi confirmado como um novo coronavírus, agora conhecido como coronavirus de síndrome respiratória aguda grave 2 (SARS-CoV-2). Não existem atualmente medicamentos autorizados para o tratamento de COVID-19, nem estão também autorizadas quaisquer vacinas. Assim, o estudo teve como objetivo realizar uma revisão sobre a utilização de Remdesivir em pacientes com COVID-19. As seguintes bases de dados eletrônicas foram utilizadas MEDLINE, SCIELO, LILACS e PUBMED. Em primeiro de maio, o Redemsivir recebeu autorização de uso de emergência da Food and Drug Administration. Remdesivir é presentemente a molécula promissora no tratamento da COVID-19 tendo em conta o seu largo espetro antiviral (considerando as sequências genéticas do vírus, é expectável que mantenha atividade contra o SARS-CoV-2). A informação in vitro e in vivo está disponível para os coronavírus, assim como a extensiva base de dados de segurança clínica (proveniente de ensaio clínico do vírus Ebola e no contexto do Monitored Emergency Use of Unregistered and Investigational Interventions - MEURI). A realização de novos estudos torna-se relevantes uma vez que os dados disponíveis são limitados sobre eficácia e segurança do Remdesivir contra SARS-nCoV-2.
