Transporte aéreo e consumo: o Recurso Extraordinário 636.331 - STF à luz do diálogo de fontes e do princípio da vedação ao retrocesso
Authors: Verbicaro Dennis , Leal Pastora Do Socorro Teixeira , Freire Gabriela Ohana Rocha
Published: August 2019

Sob a ótica do transporte aéreo brasileiro, o presente artigo analisa o Recurso Extraordinário 636.331 STF à luz do diálogo de fontes e do princípio da vedação ao retrocesso na seara consumerista. Utilizou-se o método dedutivo de investigação, a partir de pesquisa bibliográfica nacional e estrangeira, tendo como resultado que a limitação do quantum indenizatório à título de danos materiais e a redução do prazo prescricional para ajuizamento de ação reparatória ferem de morte a ideia de integração das normas (CDC e Convenção de Varsóvia / Montreal), bem como retrocedem socialmente os direitos do consumidor, transferindo à parte mais vulnerável da relação o risco do negócio, ao qual deve ser suportado pelo fornecedor.

Published: August 2019

Trata-se de um estudo sobre a ação clínica de psicólogos voltada para a prevenção em saúde, ressaltando o fenômeno da violência contra a mulher. Para tanto, foi realizada uma revisão bibliográfica com o uso da estratégia PICO. Inicialmente, apresentamos uma compreensão sobre o sentido da clínica na perspectiva fenomenológica existencial. Em seguida, informamos sobre prevenção em saúde no cerne da ação clínica psicológica voltada ao fenômeno da violência contra a mulher. Nessa perspectiva, ressaltamos a importância de repensar a prática psicológica em direção à prevenção de agravos ao sofrimento humano em situações de violência. A intervenção do psicólogo pode viabilizar o atendimento individual ou grupal às mulheres e aos seus familiares, no sentido de compreender e acolher o seu sofrimento e suas repercussões no viver cotidiano; bem como consolidar os laços sociais e comunitários.

Published: August 2019

A saúde mental pode ser definida como um equilíbrio cognitivo-emocional dos sujeitos. O movimento da Reforma Psiquiátrica trouxe a possibilidade de novas formas de intervenções em saúde mental a sujeitos com algum tipo de patologia psíquica. Dessa forma, surgiram os Centros de Atenção Psicossocial (CAPS). Esse artigo refere-se a um relato de experiência desenvolvido em uma prática da psicologia em um CAPS. A presente pesquisa teve como objetivos identificar quais mudanças a reforma psiquiátrica trouxe para a prática psicológica e compreender o papel do psicólogo no CAPS da cidade de Teresina-PI. O método para este relato baseou-se em estudos teóricos, documentos oficiais, observação participante e experiência pessoal para relatar a cronologia do planejamento e desenvolvimento das ações que foram realizadas na unidade. Os resultados possibilitaram compreender a atuação do psicólogo diante das atividades realizadas na instituição, como oficinas terapêuticas, visitas domiciliares, matriciamentos, passeios em grupo e triagens, compreendendo as competências e habilidades teóricas e técnicas necessárias para o desempenho ético e eficaz da profissão, com base nas mudanças ofertadas perante a reforma psiquiátrica. Conclui-se que as novas práticas implantadas na rede de saúde mental ofertam em um maior cuidado e uma autonomia dos usuários, possibilitando o protagonismo diante de suas vivências.

Published: August 2019

Purpose: This study explores the contribution of Shah Wali Allah al-Dehlavi’s work on the Quran to classify it into five categories (themes) using a qualitative methodology known as thematic analysis in today’s world of research, in his book Al-Fawz al-Kabir. This paper is an attempt to show the contributions of Muslim scholars in the world of research by introducing the research methodology which is used even in today’s modern world.

Methodology: A qualitative comparative analysis was employed by reviewing both the approaches such as Thematic Analysis and the approach applied by Shah Wali Allah to find five sciences.

Main Findings: The result showed that both research approaches are similar. This study concludes that [our] classical scholars have formulated and used the research methodologies which may be applicable and relevant to the current research paradigms.

Applications: This article can be used as a gateway by academics to review and analyze the work of Islamic classical scholars specifically their research techniques to derive new research methodologies.

Novelty/Originality: The work of Shah Wali Allah (SWA) on the Quran to find out the relationship between the research methodology employed by SWA and the Thematic Analysis has been studied.

Evaluación de la sensibilidad de la pared abdominal y ubre en vacas lecheras poscesárea por laparotomía en el flanco izquierdo
Authors: Saldivia Paredes Manuel Alexis
Published: August 2019

Este estudio tiene el objetivo de demostrar la pérdida de sensibilidad en la pared abdominal izquierda y primer cuarto craneal, en hembras bovinas productoras de leche sometidas a laparotomía por el flanco izquierdo con histerotomía, mediante pruebas de sensibilidad profunda en la pared abdominal y el pezón. Se incluyeron hembras bovinas sometidas al procedimiento quirúrgico de cesárea, con más de 90 días posintervención. El estudio se realizó en los sectores de la comuna de Ancud, Chiloé. Respecto a los predios, se recopiló información de los productores y médicos veterinarios de la zona para obtener datos vinculados con tipo de cirugía y consecuencias quirúrgicas. Para determinar la sensibilidad en el flanco y en la ubre, se dividieron estas zonas en seis cuadrantes, asignándoles letras (A, B, C, D, E, F); cada una de estas áreas forma parte del recorrido de los nervios espinales torácicos y lumbares evaluados en este estudio. Los resultados mostraron que el 54 % de las hembras sometidas al procedimiento de cesárea presentaron poca o nula sensibilidad en el flanco y en la ubre, condición que se manifiesta mayoritariamente en los cuadrantes C, D, E y F para ambas zonas anatómicas. Al evaluar la presencia de lesiones en la pared abdominal izquierda y en la ubre, las laceraciones fueron las más frecuentes en ambas zonas anatómicas. En el esfínter del pezón también se vio afectado, pues se observó un retado de esta estructura anatómica. Cerca del 50 % de las hembras sometidas a cesárea presentaron mastitis en los cuartos craneales en su mayoría
Electrolitos, frecuencia cardiaca y variabilidad de la frecuencia cardiaca en el periparto de vacas holstein
Authors: Cedeño Quevedo Darío Alejandro , Daza Bolaños Carmen Alicia
Published: August 2019

No existen estudios que correlacionen electrolitos con la frecuencia cardiaca (FC) y la variabilidad de la frecuencia cardiaca (VFC) en el periparto de vacas. En teoría las concentraciones de electrolitos en suero pueden afectar la VFC directamente al influir sobre la excitabilidad del músculo cardiaco. Se estudiaron 23 vacas de la raza holstein. Los índices de VFC se analizaron en seis momentos mediante la electrocardiografía. Se evaluaron los índices en el método del dominio del tiempo y frecuencia, desviación estándar de las diferencias entre latidos consecutivos (SDNN), raíz cuadrada del promedio de las diferencias entre intervalos sucesivos elevadas al cuadrado (RMSSD), baja frecuencia (LF) y alta frecuencia (HF), así como la relación LF/HF. Se midieron las concentraciones de Ca2+, Mg2+ y Pi por medio de espectrofotómetria y Na+ y K+ mediante fotometría. La FC aumentó en el día antes del parto y luego disminuyó después del parto. Los índices parasimpáticos de RMSSD y HF aumentaron. El índice simpatovagal de relación LF/HF disminuyó significativamente. Las concentraciones de los electrolitos Ca2+ y Pi disminuyeron después del parto mientras el Na+ aumentó. El día antes del parto el índice LF aumentó, mientras que la HF disminuyó, lo que indica la modulación de la FC y la ventilación por el nervio vago. El K+ un día antes del parto mostró una fuerte asociación con el índice de HF. El día después del parto la correlación entre el K y la FC, HF y LF mostró una fuerte asociación

Authors: Gheno Ediane Maria , Guaragna Regina Maria , Da Mata Luiz Felipe Sfoggia , Duarte Lucimara Figueira , Souza Diogo Onofre , Calabró Luciana
Published: August 2019

O Sistema de Avaliação da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) exige dos Programas de Pós-Graduação constante reflexão sobre o desempenho recomendado e o alcançado. Diante da importância de informações para subsidiar o planejamento, este artigo objetiva apontar novos indicadores e procedimentos que poderiam contribuir para aprimorar as políticas de avaliação da CAPES nos Quesitos três (Corpo Discente, Teses e Dissertações) e cinco (Inserção Social). É um estudo metodológico, elaborado a partir de um monitoramento e avaliação, 2007-2016, aplicando Análise Documental e indicadores bibliométricos/cientométricos, tendo o Programa de Pós-Graduação em Ciências Biológicas: Bioquímica da Universidade Federal do Rio Grande do Sul como um estudo de caso. Para isso buscou: analisar o desempenho do Programa com base nas diretrizes da Área Ciências Biológicas II; avaliar a nucleação de egressos nas Instituições de Ensino Superior; identificar as medidas corretivas e avaliar, através da produção científica, o impacto das Portarias (Portarias dos 8) que recomendam no máximo oito discentes por docente. Para atingir os objetivos, apresentam-se três procedimentos e um novo indicador científico. Os procedimentos aprimoraram a avaliação sobre as contribuições do Programa para a nucleação e sobre o perfil da formação dos egressos. O outro procedimento está relacionado à gestão, que identifica os efeitos da avaliação da CAPES pelas medidas corretivas. O indicador de coautoria discente/docente aponta a inviabilidade das Portarias dos 8, pois o número de discentes por docente não afeta a produção científica por discente. Os procedimentos e o indicador de coautoria podem ser utilizados como parâmetros adicionais à avaliação da CAPES, contribuindo no aprimoramento da Avaliação Institucional dos Programas.

Authors: De la O Ledesma Santa , López Ocaña Gaspar , Rodríguez Rodríguez Ernesto
Published: August 2019

La población de Villa Unión, en Centro, Tabasco, requiere de agua potable. Estas localidades originan un aporte de 13,633.20 m3/día de agua residual doméstica mezcladas con agua potable, del cual se trata solamente el 53.6 % de dicho caudal en una planta de tratamiento de humedales artificiales. Al respecto dichas aguas residuales se descargan al arroyo Macultepec, la laguna El Calabozo y la laguna Paso Segundo. No obstante, de continuar descargándose el agua residual en forma directa, se agilizará el proceso de eutrofización de las lagunas. Para detener este problema es urgente que se rehabiliten y pongan en operación las plantas de tratamiento de los fraccionamientos Lomas de Ocuiltzapotlán II, ISSET y Lomas de Ocuiltzapotlán, y así aumentar el volumen de agua tratada.

Fluxes of Gaseous Elemental Mercury at a Mediterranean Coastal Grassland
Authors: Polyzou Christiana , Loupa Glykeria , Trepekli Aikaterini , Rapsomanikis Spyridon
Published: August 2019

Coastal rural areas can be a source of elemental mercury, but the potential influence of their topographic and climatic particularities on gaseous elemental mercury (GEM) fluxes have not been investigated extensively. In this study gaseous elemental mercury was measured over Mediterranean coastal grassland located at Northern Greece from 2014 to 2015 and GEM fluxes were evaluated utilizing Monin-Obukhov similarity theory. The GEM fluxes ranged from -50.30 to 109.695 ng m-2 h-1 with a mean value equal to 10.501 ng m-2 h-1 ± 19.14 ng m-2 h-1. Concerning the peak events, with high positive and low negative GEM fluxes, those were recorded from the morning until the evening. Rain events were a strong contributing factor for enhanced GEM fluxes. The enhanced turbulent mixing under daytime unstable conditions led to greater evasion and positive GEM fluxes while during nighttime periods the GEM evasion is lower indicating the effect of atmospheric stability on GEM fluxes. The coastal grassland with its specific characteristics influences the GEM fluxes and this area could be characterized as source of elemental mercury. This study is one of the rare efforts in the research community to estimate GEM fluxes in a coastal natural site based on aerodynamic gradient method.

Authors: Endrawati Eny , Panjono Panjono , Suhartanto Bambang , Baliarti Endang
Published: August 2019

This study aims to estimate the carrying capacity of oil palm plantations with the use of herbicides based on the forage availability for Bali cows. The research was performed in palm oil plantation owned by PTPN V Riau, from March 2016 until March 2017. The parameters observed were 1) Forage production that grows between palm trees at 6 weeks cutting age. The forage sample was taken from 5 point of 1x1m2, then subjected to proximate analysis. Data were analyzed with one-way random design, 2) Forage consumption; obtained by observation of 5 pregnant Bali cow and 7 non-pregnant for seven consecutive days 3). Estimated carrying capacity for Bali cows, obtained from the calculation of forage production (/ha/year) divided by forage consumption. The result of the research showed that 1). The production of dry matter (DM) forage in herbicide-treated areas was 689.55 kg/ha/year, not significantly different compared to untreated areas (622.33 kg/ha/year). Crude protein (CP) forage content of forage obtained from herbicide-treated area was significantly higher (p<0.05) than untreated area, whereas the total content of DM and total digestible nutrients (TDN) was not significantly different. DM consumption of pregnant Bali cow was on average 3.68±0.29 kg/head/day or 1,343.20±105.85 kg/head/year and non-pregnant 4.02±0.36 kg/head/day or 1,467.30±131.4 kg/head/year. The estimated carrying capacity on herbicide-treated (0.51 head of pregnant cow/ha), did not show any significant difference compared to untreated area (0.46 head/ha). For non-pregnant, the carrying capacity of herbicide-treated area (0.47 head/ha) was not different with non-treated area (0.42 head/ha). It was concluded that the use of herbicide on palm oil plantation had no effect on the carrying capacity of the Bali cow.

This study was conducted to evaluate the effect of addition of rumen fluid enzymes of buffaloes from slaughterhouse in diet on feed intake, slaughter weight, daily weight gain, feed conversion ratio, absolute carcass weight, relative carcass weight, and digestive organs of broiler. Materials used was two hundred unsexed 1 day old chicks of broilers. The study used a completely randomized design with five treatments and four replications consisted of 10 birds each replication. Treatment groups were as follows P0 = diet  without addition of rumen fluid enzymes (control); P1 = diet  with addition of rumen fluid enzymes of 0.75%; P2 = diet with addition of rumen fluid enzymes of 1.5%; P3= diet with addition of rumen fluid enzymes of 2.25%; P4=  diet with addition of rumen fluid enzymes of 3%. The variables observed were feed intake, slaughter weight, daily weight gain, feed conversion ratio, absolute carcass weight, relative carcass weight, and digestive organs. Results of the study showed that the treatments gave a non-significant different (P>0.05) on feed intake, slaughter weight, daily weight gain, feed conversion ratio, absolute carcass weight, relative carcass weight, and digestive organs of broiler chicken.  It could be concluded that the use of rumen fluid enzymes of buffaloes in the diets up to 3% level did not increase performance and digestive organs of broiler chicken.
Solution of Contact Problem for Supporting Node of Beam Hinged Plate
Authors: Bosakov S. V. , Skachok P. D.
Published: August 2019

The paper considers a solution of contact problem for hinged supporting node of beam floor slab (coating). The main goal is to determine a stress state of the area where a plate rests on the wall. In this case, a number of problems are solved: construction of reactive pressure diagrams in the area of direct plate and wall contact, clarification of the calculated plate span, influence of contact zone size on a value of maximum bending moment in the middle of the plate, determination of contact area at various indices of flexibility and comparison of the obtained results with the known solution of rigid stamp and elastic quarter-plane interaction. The calculation has been carried out by the Zhemochkin method, its implementation for the given task corresponds to a mixed method of structural mechanics. As an illustration, the calculation has been performed on a concentrated load applied in the middle of the plate span. In the course of the study, it has been established that when a reinforced concrete slab rests on concrete and brick walls, the contact zone reduces itself to two Zhemochkin sections. When a flexibility index is decreased that corresponds to slab support on a less rigid base, the contact area is increased, and that, in its turn, has an influence on an increase of the calculated slab span and the bending moment in the middle of the slab. In the case of an absolutely rigid plate support (flexibility index is equal to zero), the contact stresses reach their maximum value at the point of plate edge contact and elastic quarter-plane. The nature of the diagram is confirmed by an analytical dependence of contact stress distribution obtained by Aleksandrov V. M. when solving a problem of pressing a rigid stamp into an edge of an elastic wedge.
Implementation of an interactive organ donation education program for Dutch lower-educated students: a process evaluation
Authors: Steenaart Esther , Crutzen Rik , de Vries Nanne K
Published: August 2019

Background

As organ donation registration rates remain low, especially among lower-educated people, it is important to support this group in making their registration decision. To prepare lower-educated students in the Netherlands for making a well-informed decision, an interactive educational program was developed. We aim to understand both the (quality of) implementation as well as to contextualize the effect of this program in a lower-educated school setting.

Methods

The process evaluation was part of a Cluster Randomized Controlled Trial, in which 11 schools for Intermediate Vocational Education throughout the Netherlands participated. Teachers who taught a course on Citizenship delivered three intervention elements (i.e. video fragments and discussion, quizzes with tailored feedback and an exercise filling out a registration form) to their students. Implementation was assessed by interviews with teachers, questionnaires from students, logbooks from teachers and user data from Google Analytics.

Results

The program was well received and implemented, but on-the-spot adaptations were made by teachers to fit their students better. Within the lower-educated target group, differences between students are high in terms of active participation, reading abilities, knowledge and attention span. The program fit well within their regular teaching activities, but the topic of organ donation is not always prioritized by teachers.

Conclusions

We see opportunities to disseminate the program on a larger scale and reach a group that has been neglected in organ donation education before. Within the program, there are possibilities to increase the effectiveness of the program, such as alternative delivery methods for the elements with a lot of text, the addition of booster sessions and guidelines for teachers to adapt the program to students of different levels within Intermediate Vocational Education. Moreover, in order to have an impact on a national level, strategies need to be employed to reach high numbers of students and, therefore, support on a higher level is needed (both within schools and at policy level).

Authors: Min Zhigang , Shan Hairong , Xu Long , Yuan Daihai , Sheng Xuexia , Xie Wenchao , Cao Zhi-hong
Published: August 2019

Background
The purpose of this study was to verify the pathological heterogeneity of white matter hyperintensities (WMHs). We compared diffusion tensor imaging (DTI) metrics within different brain regions using identical grading protocols, and subsequently investigated the microstructural changes in these areas as the WMH progressed.
Methods
Seventy-three patients with WMH and 18 healthy controls who received DTI were included in this study. We measured fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (DA), and radial diffusivity (DR) of periventricular and deep WMH in six brain regions and grouped these measures according to the Fazekas scale. We then compared the DTI metrics of different regions with the same Fazekas scale grade.
Results
Significantly lower FA values (all p<0.001), and higher MD (all p<0.001) and DR values (all p<0.001) were associated with WMH observed within the periventricular white matter around the frontal horn (pFH) and the frontal lateral ventricle (pFLV) compared to other regions with the same Fazekas grades. However, in the normal white matter of the pFH and pFLV, FA was not significantly lower than all other regions. Furthermore, in these areas, MD, DA, and DR were not significantly higher than in all other regions.
Conclusion
Distinct pathological processes occurred within frontal periventricular WMH and other regions; these processes may represent the effects of severe demyelination within the frontal periventricular white matter.

Background

Detection of somatic mutations in tumor tissues helps to understand tumor biology and guide treatment selection. Methods such as quantitative PCR can analyze a few mutations with high efficiency, while next generation sequencing (NGS) based methods can analyze hundreds to thousands of mutations. However, there is a lack of cost-effective method for quantitatively analyzing tens to a few hundred mutations of potential biological and clinical significance.

Methods

Through a comprehensive database and literature review we selected 299 mutations associated with colorectal cancer. We then designed a highly multiplexed assay panel (8-wells covering 299 mutations) based on an automated MADLI-TOF mass spectrometry (MS) platform. The multiplex panel was tested with a total of 319 freshly frozen tissues and 92 FFPE samples from 229 colorectal cancer patients, with 13 samples also analyzed by a targeted NGS method covering 532 genes.

Results

Multiplex somatic mutation panel based on MALDI-TOF MS detected and quantified at least one somatic mutation in 142 patients, with KRAS, TP53 and APC being the most frequently mutated genes. Extensive validation by both capillary sequencing and targeted NGS demonstrated high accuracy of the multiplex MS assay. Out of 35 mutations tested with plasmid constructs, sensitivities of 5% and 10% mutant allele frequency were achieved for 19 and 16 mutations, respectively.

Conclusions

Automated MALDI-TOF MS offers an efficient and cost-effective platform for highly multiplexed quantitation of 299 somatic mutations, which may be useful in studying the biological and clinical significance of somatic mutations with large numbers of cancer tissues.

Published: August 2019

Backgroud: Accurate diagnosis of cancer staging and pathological differentiation are critical for the formulation of individualized treatment and prognosis of gastric cancer. It is vital to explore non-invasive preoperative imaging techniques to evaluate the pathological differentiation degree of gastric cancer tissues, and provide better diagnostic basis and decision-making reference for treatment. The purpose of this study was to explore the clinical value of energy spectrum curves of dual-source dual-energy CT in the quantitative evaluation of different pathological grades of gastric adenocarcinoma.
Methods: A total of 62 patients with 1 well, 25 moderately and 36 poorly differentiated gastric adenocarcinomas pathologically confirmed by surgery were collected, and they underwent dual-source dual-energy CT plain scanning and enhanced scanning before operation. Dual-Energy software was used to measure the slope of the energy spectrum curves (λ) in arterial and venous phases after image reconstruction. Patients were divided into two groups according to the pathological results, including well and moderately differentiated gastric adenocarcinoma group and poorly differentiated gastric adenocarcinoma group. Data of each group were analyzed by independent sample t-test. The receiver operating characteristic curve was plotted to evaluate the diagnostic efficiency of the corresponding parameters.
Results: There were significant differences in λ values of 40-50keV, 40-60keV, 40-80keV, 40-90keV, 40-100keV, 40-120keV, 40-130keV, 40-140keV and 40-150keV energy ranges in venous phase between the well and moderately differentiated group and poorly differentiated group (P<0.05), but no significant differences in λ values of different energy ranges in arterial phase between the two groups (P>0.05). And the area under curve in 40-120keV energy range was the largest in venous phase. K40-120keV =2.69 was selected as the diagnostic threshold with the maximum Youden index, the sensitivity and specificity were 61.1% and 76%, respectively.
Conclusion: The energy spectrum curve of dual-energy CT had certain diagnostic value in the quantitative evaluation of pathological grading of gastric adenocarcinoma.

Published: August 2019

AIM

To evaluate epidemiology and demographic data of patients diagnosed with Barrett’s esophagus in University Hospital Centre Zagreb between January 2012 and December 2017.

MATERIALS AND METHODS

In a 6 year period, upper GI endoscopy was performed in 19950 patients. We have analysed endoscopy and hospital database regarding pathohistological confirmation and demographic data of patients diagnosed with Barrett’s esophagus .

RESULTS

Endoscopy suspicion of esophageal metaplasia (ESEM) was made in 592 patients. Pathohistological confirmation of Barrett’s esophagus was established in 163 patients (0.8%). Intestinal metaplasia without dysplasia was diagnosed in 137 patients, low grade dysplasia in 20 patients, high grade dysplasia in three and early cancer in three patients.

In the group of 163 patients with confirmed Barrett’s esophagus 116 (71%) were male and 47 (29%) were female with median age of 58 years. Hiatal hernia was observed during endoscopy in 92 patients (56%).

Patients with high grade dysplasia and early cancer have been treated with bandEMR and then radio frequency ablation (RFA), and all the patients with confirmed low grade dysplasia have been treated with RFA.

CONCLUSION

Barrett’s esophagus still has a low incidence in Croatia, even in a high volume tertiary referral Centre.
HbA1C as a potential Biomarker of Non-Alcoholic Fatty Liver Disease: comparison with BMI, WHR and WC
Authors: Masroor Muhammad , Haque Zeba
Published: August 2019

Background: Nonalcoholic fatty liver disease (NAFLD) is a slow progressing disease common in obese and diabetic individuals. Present study attempts to establish association of glycosylated hemoglobin (HbA1C) with NAFLD and its severity, compared with body mass index (BMI), waist to hip ratio (WHR) and waist circumference (WC).
Methods: This case control study was conducted on a sample of 450 individuals including 150 cases and 300 age and gender matched controls recruited from Dow Radiology Institute through convenient sampling. Severity of the disease among cases was determined upon ultrasonic evidence. Detailed history and physical examination was recorded. HbA1C was determined by TINIA method. The study was part of a project funded by Higher education of Pakistan.
Results: Among the cases 66% whereas 32% of controls had HbA1C levels more than normal value (5.7%). HbA1C, type II DM and BMI were significantly associated with NAFLD (cOR= 4.12, 2.88, 2.25 (overweigh) and 4.32 (obese) respectively)..WC was found significantly associated with NAFLD in both genders (cOR in males= 5.50 and females= 5.79, p<0.01). After adjustment with BMI and Type II DM, HbA1C was found significantly associated with NAFLD (aOR=3.40, p<0.001) along with BMI more than 30Kg/m2 (aOR= 3.30, p< 0.001). After stratification of data on the basis of gender HbA1C and WC remained significant (aOR= 2.08 and 2.91, p<0.05 respectively) while BMI became insignificant (aOR= 1.65 and 1.73, p>0.05 for overweight and obese) in males. In females, HbA1C, WC and BMI (only in obese individuals) were found significantly associated (aOR=5.20 p<0.001, 4.28 p=0.035 and 2.90 p=0.029) respectively. AUC for HbA1C was valid for total population (0.76, CI; 0.715 – 0.809) males (0.706, CI; 0.629 – 0.783) and females (0.80, CI; 0.741 – 0.858).
Conclusion: HbA1C level is significantly associated with presence of NAFLD and possesses a valid predictability value in both diabetic and non-diabetic individuals. It is the single risk factor that is strongly associated with NAFLD after adjustment with BMI, WHR and WC. HbA1C may be presented as a potential biomarker for NAFLD examined with WC in adult population. Evaluation of HbA1C for potential biomarker for NAFLD merits more studies in other settings.

Authors: Govender Romona Devi , Al-Shamsi Saif , Soteriades Elpidoforos S. , Regmi Dybesh
Published: August 2019

Background

Individuals with established cardiovascular disease (CVD) are at a much higher risk of either recurrent cardiovascular events or death. Previous research has shown that the incidence rate for recurrent CVD events varies across countries and populations. The association of traditional CVD risk factors, such as age, smoking, hypertension and diabetes mellitus increases the risk of recurrent CVD events or death particularly in individuals with a history of cardiovascular disease (CVD). The United Arab Emirates (UAE) has one of the highest age-standardized death rate for CVD worldwide. The aim of our study was to estimate the incidence rates and determine the predictors of recurrent CVD events among UAE nationals.

Methods

We investigated an outpatient-based cohort of patients with a history of prior CVD visiting Tawam Hospital between January 1, 2008 and December 31, 2008 and followed-up until the end of study period, July 31, 2018. Univariable and multivariable-adjusted Cox proportional hazard regression models were used to explore the association between different major CVD risk factors and the risk of recurrent CVD.

Results

A total of 216 patients (167 males, 49 females) with a history of CVD were included in our study. They were followed for a median of 8.1 years (interquartile range 5.5 to 9.3 years), with a total of 1184 patient-years of follow-up. The overall incidence rate of recurrent CVD events was 92.1 per 1000 patient-years. The 8-year cumulative incidence was 73.7%. Age, female sex, and diabetes mellitus were significant predictors of recurrent CVD events. Females had an 85% higher probability of recurrent CVD than males.

Conclusion

The overall incidence rate of recurrent CVD events in the UAE is 92.1 per 1000 patient-years and is one of the highest in Middle Eastern region. Primary and tertiary preventive measures are urgently needed in order to improve CVD morbidity and mortality and attempt to reverse the alarming rates of new and recurrent CVD events among UAE nationals. These interventions should comply with international guidelines for CVD management.
Feto-maternal Outcomes of Hypertensive Disorders of Pregnancy in Yekatit-12 Teaching Hospital: a Retrospective Study
Authors: Mengistu Mekoya Dabulo , Kuma Tilahun
Published: August 2019

Background

In resource poor countries, hypertensive disorders of pregnancy are common and form one of the deadly triad, along with hemorrhage and infection, which contribute greatly to maternal and fetal jeopardy.

Methods

The aim of this study was to assess the prevalence of hypertensive disorders of pregnancy, and determine the effects of hypertensive disorders of pregnancy on the feto-maternal outcomes. It was a descriptive, cross-sectional, retrospective study on 615 women who attended delivery at Yekatit-12 Teaching Hospital from July 2017 - Jan 2018. Data was analyzed using SPSS version 20 software. Descriptive statistics were used to calculate rates. Chi-square statistics were used to estimate the associations among selected predictor variables. A p-value < 0.05 was taken as statistically significant.

Results

Out of the 615 study population, the prevalence of hypertensive disorders of pregnancy was found to be 25.4%, of which the majority (54.5%) was severe pre-eclampsia. Eclampsia accounted for 2.6%, and superimposed pre-eclampsia was 2.6%. The rate of severe pre-eclampsia with HELLP syndrome was 7.1% of all mothers with the hypertensive disorders. The majority of mothers with hypertensive disorders (59.6%) had age range of 25-34 years. About 46% of mothers required interventions to terminate the pregnancy either by cesarean section (42.3%) or instrumental deliveries (3.7%). The rate of preterm, low birth weight, and low Apgar at 1st and 5thminutes accounted for 30%, 25%, 24.4% and 16.7% of neonates born to mothers with hypertensive disorders, respectively. Over 19% of neonates required resuscitation and 11.5% NICU referral. The rate of still birth was 2.6%.

Conclusion

The prevalence of hypertensive disorders of pregnancy is high in the study area and complicates maternal and fetal outcomes of the pregnancy. To deter its detrimental effects both on fetal and maternal outcomes of pregnancy, antenatal surveillance should be expanded to enable early detection, stringent follow-up and timely intervention in severely affected pregnancies.
