Manifestações atípicas em pacientes com Dengue: revisão de literatura

A dengue é um grande problema de saúde pública, o qual afeta principalmente a população das regiões tropicais e subtropicais no mundo, além dos milhares de viajantes que visitam essas áreas. A transmissão ocorre através da picada dos vetores fêmeas do Aedes aegypti, Aedes albopictus, Aedes scutellari ou Aedes polynesiensis, infectados pelo vírus, podendo levar a manifestações desde assintomática a febre hemorrágica. Dessa maneira, o estudo realizado é uma revisão integrativa da literatura, descrita como um método de pesquisa que permite a busca, a avaliação crítica e a síntese das evidências disponíveis do tema investigado, sendo utilizado vinte artigos para realização dele. Assim, a dengue pode ter sua manifestação por diversas maneiras, desde infecção assintomática a febre indiferenciada, dengue hemorrágica ou dengue por síndrome de choque. Logo, ressalta-se a importância do conhecimento detalhado de todas as manifestações que pode acometer o paciente com dengue, além de executar um exame clínico bem detalhado, fazendo uso de meios complementares para diagnóstico, tais como exames específicos. O tempo é fundamental nessa hora, visto que pode favorecer o prognóstico do paciente, evitando futuras complicações.

Performance of MALDI-TOF Mass Spectrometry to Determine the Sex of Mosquitoes and Identify Specific Colonies from French Polynesia

Mosquitoes are the main arthropod vectors of infectious diseases in humans. The current methods for mosquito identification include morphological and molecular methods. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), now routinely used for bacterial identification, has recently emerged in the field of entomology. The aim of this study was to use MALDI-TOF MS to identify mosquito colonies from French Polynesia. Five hundred specimens from French Polynesia belonging to three species, Aedes aegypti, Aedes polynesiensis, and Culex quinquefasciatus, were included in the study. Testing the legs of these mosquitoes by MALDI-TOF MS revealed a 100% correct identification of all specimens at the species level. The MALDI-TOF MS profiles obtained allowed differentiation of male from female mosquitoes and the specific identification of female mosquito colonies of the same species but different geographic origin.

Pedamuk Menciptakan Lingkungan Sekolah Berkualitas Menuju Revolusi Industri 4.0

<p><em>Sampah menjadi permasalahan yang dapat menimbulkan dampak buruk bagi masyarakat, Permasalahan sampah dimulai sejak meningkatnya jumlah manusia dan hewan penghasil sampah (Suyono dan Budiman, 2010). Sampah menyebabkan berkembangnya beragam penyakit, terutama penyakit yang dibawa oleh vektor, yakni organisme penyebar agen pathogen dari inang ke inang, seperti nyamuk yang banyak menularkan penyakit. Demam Berdarah Dengue (DBD) atau Dengue Haemorrhagic Fever (DHF) merupakan salah satu penyakit yang disebabkan oleh nyamuk spesies Aedes Aegypti dan aedes albopictus (DBD, 1999) sebagai vector primer, serta Aedes polynesiensis, Aedes scutellaris serta Ae (Finlaya) niveus sebagai vektor sekunder. Dengan permasalahan tersebut, maka penelitian ini membahas tentang solusi yang efektif untuk mendeteksi nyamuk sebagai solusi pencegahan nyamuk di lingkungan sekolah. Penelitian ini membahas tentang bagaimana kesadaran masyarakat di lingkungan sekolah terhadap sampah yang dapat menyebabkan nyamuk berkeliaran dan meningkatkan korban penderita DBD (Demam Berdarah Dengue) pada anak-anak. Pendeteksi ini menggunakan Arduino Uno sebagai kontroller, Sensor Ultrasonik sebagai pendeteksi nyamuk, Serial Monitor sebagai alat pantau nyamuk. Dengan demikian, kesadaran dan kepedulian para siswa terkhususnya anak sekolah terhadap penanggulangan sampah akan meningkat dari sebelumnya. Inovasi ini juga dapat menjadi inovasi yang dapat menuju revolusi industri 4.0, karena lebih mengenalkan teknologi berbasis digital kepada anak sekolah.</em></p><p><em>Kata Kunci: Sampah, nyamuk, pendeteksi nyamuk, kesadaran anak sekolah, penanggulangan, revolusi industri 4.0</em></p><p align="center"><strong>Pedamuk Create A Quality School of Environment towards Industrial Revolution 4.0</strong></p><p><strong>ABSTRACT</strong></p><p><em>Waste becomes a problem that can cause adverse effects to the community, the problem of waste </em><em>is </em><em>started from the increasing number of people and waste-producing animals (Suyono and Budiman, 2010). Garbage will develop a variety of diseases, especially those carried by vectors, namely pathogenic agents that spread from host to host, such as mosquitoes which transmit diseases. Dengue Haemorrhagic Fever (DHF) is one of the diseases caused by mosquitoes Aedes Aegypti and Aedes albopictus species (DHF, 1999) as primary vectors, and Aedes polynesiensis, Aedes scutellaris and Ae (Finlaya) niveus as vectors secondary. With these problems, this study discusses an effective solution to detect mosquitoes as a mosquito prevention solution in the school environment. This study discusses how public awareness in the school environment is about waste that can cause mosquitoes to roam and increase victims of dengue fever (Dengue Hemorrhagic Fever) in children. This detector uses Arduino Uno as a controller, Ultrasonic Sensor as a mosquito detector, Serial Monitor as a tool to monitor mosquitoes. Thus, the awareness and concern of the students especially the school children towards waste management will increase from before. This innovation can also be an innovation that can lead to a 4.0 industrial revolution because it introduces more digital-based technology to school children.</em></p><p><em>Keywords: Waste, mosquito, mosquito detection, awareness of school children, countermeasures, industrial revolution 4.0</em></p>

Identify and Predict Environmental Change Effects On Tiger Mosquitos, Aedes Polynesiensis

SummaryTo control mosquito populations for managing vector-borne diseases, a critical need is to identify and predict their response to causal environmental variables. However, most existing attempts rely on linear approaches based on correlation, which cannot apply in complex, nonlinear natural systems, because correlation is neither a necessary nor sufficient condition for causation. Appling empirical dynamic modelling that acknowledges nonlinear dynamics on nine subpopulations of tiger mosquitos from three neighbouring reef islets of the Raiatea atoll, we identified temperature, precipitation, dew point, air pressure, and mean tide level as causal environmental variables. Interestingly, responses of subpopulations in close proximity (100-500 m) differed with respect to their causal environmental variables and the time delay of effect, highlighting complexity in mosquito-environment causality network. Moreover, we demonstrated how to explore the effects of changing environmental variables on number and strength of mosquito outbreaks, providing a new framework for pest control and disease vector ecology.
