We are well aware of the many problems that our current generations are facing. From all these new enhancements in the real world, it has been quite hard for them to keep up with everything evolving around them. Keeping all this in mind, they work day in and out to make sure that their knowledge of their surroundings up to date. However, we believe that they fail to take care of themselves in the process correctly. No matter how much a particular individual may withstand in terms of workload, stress, or other mental & emotional barriers, our physical body will always be the critical aspect to overcoming them. Most people believe that working out and maintaining physical fitness are the significant aspects to sustain an excellent physical form, but they simply overlook the most crucial element which is their eating habits [1]. Although our body may be physically fit, the nourishment of our body depends on the eating styles that we follow on a day to day basis. Food is what nourishes our body with most of the proteins & minerals that we require; without it, we wouldn't be able to accomplish much. On conducting worldwide research on people's lifestyles, we were able to conclude that over the past 33 years, the obesity rate among human beings has increased by a mere 27.5%. What seems to be the most thoughtful yet intriguing fact is that although many people are overweight as well as obese, they still believe that their eating habits are healthy [2]. Most people are living in the dilemma of the fact that they maintain a healthy lifestyle. We aim to study the views on a healthy lifestyle as per the norms of our current generation. We want to analyze their daily eating habits as well as their thoughts on their lifestyle. So the question that remains is “What exactly is a Healthy Eating Lifestyle?”[3]To know the accuracy of our data set we use the machine learning algorithms like Support Vector Machine (svm), Naïve-Bayes Classifier which are used for both classification and regression [4].

The number of major road accidents that occur per day is on a rise and most of them are attributed to being the driver’s fault. According to the survey done in 2015, drivers are held responsible for approximately 78% of the accidents. To minimize the occurrence of these incidents a monitoring system that alerts the driver when he succumbs to sleep is proposed. This algorithm processes live video feed focused on the driver’s face and tracks his eye and mouth movements to detect eye closure and yawning rates. An alarm sounds if the driver is drowsy or already asleep. Haar-cascade classifiers run parallelly on the extracted facial features to detect eye closure and yawning.

A Síndrome de Stevens-Johnson é uma reação idiossincrática grave e rara que atinge em torno de 1,2 a 6 pessoas por milhão de pessoas por ano. É causada na maioria das vezes, 50% a 80%, por uma reação de hiperssensibilidade tardia à fármacos, porém, outras etiologias, como infecções bacterianas e virais também podem desencadear a síndrome. É caracterizada por lesões mucocutâneas com padrão eritematoso ou purpúrico, que confluem em tronco e face que aparecem após 4 a 28 dias do início  do uso da medicação. A maior complicação da Síndrome de Stevens-Johnson é a sepse, e a mortalidade geralmente não ultrapassa 5%. O tratamento inicial é feito com a retirada das medicações, que possivelmente estão causando a síndrome, e por medidas de suporte. Neste trabalho foi relatado o caso de uma paciente do sexo feminino de 56 que apresentou lesões de pele, compatíveis com a Síndrome de Stevens-Johnson, após fazer o uso de fenitoína concomitante com sulfametoxazol-trimetroprima, para profilaxia de crises convulsivas após realização de neurocirurgia para drenagem de hematoma intraparenquimatoso por complicação de ressecção de tumor cerebral e para tratamento de infecção do trato urinário, respectivamente. A paciente teve boa evolução clínica das lesões após a retirada da medicação.

Introdução: a meningite consiste em uma doença endêmica no Brasil que apresenta surtos e epidemias ocasionais. Objetivo: avaliar o perfil epidemiológico da meningite em um município da Região Sul do Brasil. Métodos: estudo descritivo que analisou a situação epidemiológica da meningite em um município da Região Sul do Brasil com foco na etiologia mais comum. O estudo utilizou dados secundários obtidos a partir do Sistema de Informação de Agravos de Notificação do município de Cascavel-PR no período de 2008 a 2018. Resultados: os casos de meningite acometeram, em sua maioria, a raça branca e o sexo masculino. Houve maior frequência de etiologia asséptica e presença de quadro clínico com cefaleia, febre e vômitos. A complementação diagnóstica foi realizada por meio de exame quimiocitológico de líquor. A maioria dos pacientes evoluíram para alta hospitalar. Conclusão: apesar da escassez de estudos sobre a temática para a construção de um comparativo, os resultados em relação aos aspectos epidemiológicos foram consistentes com a literatura. A meningite acomete, de maneira geral, pessoas do sexo masculino e apresenta etiologia asséptica majoritariamente. É necessário, portanto, o enfoque aos grupos populacionais mais comumente acometidos pela meningite.

Esse é um estudo retrospectivo realizado na cidade de Capitão Leônidas Marques, Paraná, Brasil, com objetivo de delinear o perfil municipal de dispensação de antidepressivos no período de Janeiro de 2015 à Dezembro de 2017. Os dados foram obtidos a partir dos Relatórios Trimestrais (RT) de medicamentos psicotrópicos submetidos a controle especial pela Portaria 344/98 do MS, da rede privada (farmácias) e pública (SUS e Hospital), fornecidos pela vigilância sanitária. Os Antidepressivos correspondem a 55,3% do total de psicotrópicos dispensados nesse período e o mais consumido foi Amitriptilina 25mg, sua Dose Diária Definida (DDD)/mil habitantes/dia entre 2015 e 2017 se manteve entre 4,19 – 5,16. A quantidade dispensada sugere um consumo exagerado de antidepressivos nesse Município, sendo assim, é de suma importância ter uma regulação apropriada e uma prescrição racional dessas substâncias.

Introdução: a Degeneração Hepatolenticular, conhecida como Doença de Wilson (DW), trata-se de um distúrbio autossômico recessivo raro do metabolismo de cobre, com prevalência de 1:30.000 nascidos-vivos, acomete principalmente jovens adultos. Os pacientes podem apresentar distúrbios psicomotores, oftalmológicos, doenças psiquiátricas atípicas, hemólise inexplicada, doença hepática sem outra causa aparente. Relato e discussão do caso: Paciente de 27 anos, masculino, diagnosticado com DW aos 22 anos de idade. Iniciou o quadro com queixa de elevação de pressão arterial, dislalia e ansiedade. Exames de imagens constataram depósitos de material ferromagnético nos globos pálidos, putâmens e cabeça dos núcleos caudados associadas a alteração simétrica do sinal das margens dos núcleos basais, da face posterior das cápsulas internas, mesencéfalo, ponte, bulbo e pedúnculos cerebelares superior e médio. Paciente em uso de trientina há 4 anos, encontra-se estável, porém com déficits motores. Conclusões: a DW é uma enfermidade rara e seu diagnóstico precoce implica um elevado nível de suspeita clínica em todos os pacientes, principalmente em jovens que apresentem anormalidades hepáticas e sintomas neuropsiquiátricos atípicos. O diagnóstico precoce é difícil, porém imprescindível para o tratamento específico, melhorando o prognóstico dos pacientes e evitando a progressão da doença para formas graves de doença hepática e neurológicas.

A primary requirement of a modern electric power system is reasonable ability to satisfy the customer load requirements. Electric utilities involve generation, transmission, and distribution facilities each one of which contributes its own inherent difficulties to the problem of satisfying customer requirement. A power system should be designed and expanded the facilities in order to perform its intended function with a reasonable risk. With increasing the electrical energy demand and the potential of disruption that may occur in the system, the distribution system must have high reliability and continues supply to customer. In this case, the reliability of the distribution system needs to be evaluated by monitoring and analyzing the level of distribution system failure in a certain period of time.  A study on a practical distribution system with application of automatic circuit reclosers (ACRs) which plays an important role in enhancing the reliability index of system is presented. The reliability index assessment analyze the reliability index of the existing system before and after application of ACRs. From the simulation point of view, the system average interruption frequency index (SAIFI) is about 19.43% or decreased the failure frequent event from 11.4 failure/ customer.year to 9.25 failure/customer.year); while the momentary average interruption frequency index (MAIFI) has decreased from 6.72 failure/customer.year to 5.05 failure/ customer.year, or increase the reliability index of about 24.85%.
