Authors: Alim Fathul , . Winarko , Sari Ernita 
Published: July 2020

Ikan cupang sudah terbukti sebagai pemangsa jentik aedes aegypti atau ikan bersifat karnivora yang memakan hampir semua binatang kecil yang hidup di air. Sedangkan di tempat-tempat budidaya, beberapa pakan alami yang umumnya diberikan yaitu daphnia, moina dan cacing Tubifek. Ikan cupang juga diketahui merupakan salah satu ikan predator jentik nyamuk. Ikan plati pedang termasuk ikan omnivora, tetapi lebih cenderung menyukai makanan dari tumbuh-tumbuhan. Makanan harus tersedia sejak fase larva, oleh karena itu kebanyakan pembudidaya ikan terlebih dahulu telah menyediakan atau melakukan kultur pakan alami sebelum memijahkan ikan. Menurut penelitian terdahulu ikan Xyphophorus Helleri (ikan plati pedang) dengan ukuran kira-kira 2 cm dalam waktu 1 hari dapat memangsa larva atau jentik nyamuk mencapai 116 ekor. Penelitian ini bertujuan untuk mengetahui perbedaan daya predasi ikan cupang (Betta sp.) dan ikan plati pedang (xyphophorus Helleri) terhadap larva nyamuk Aedes aegypti.Jenis penelitian ini adalah eksperimen murni yang dilaksanakan di lab. entomologi dengan desain one shoot chase study. Subyek penelitian adalah larva nyamuk Aedes aegypti instar III, ikan cupang dan plati pedang masing-masing replikasi sebanyak 16 kali. Setiap waktu pengamatan menggunakan larva instar III sebanyak 25 ekor. Pengamatan dilakukan selama 1 jam. Analisis data menggunakan independent samples test. Kriteria uji Independent Samples Test : jika nilai p value 0.000, membuktikan adanya perbedaan yang bermakna antara daya predator ikan cupang (Betta sp.) dengan ikan plati pedang (xyphophorus Helleri) terhadap larva nyamuk Aedes aegypti dan sebaliknya.Hasil penelitian menunjukan bahwa daya predasi ikan cupang dan plati pedang dalam waktu 1 jam sudah habis memangsa semua larva jentik dengan persentase 100%, sehingga dapat disimpulkan bahwa ikan Cupang dan ikan Plati Pedang selama kurun waktu 1 jam mampu memangsa larva Aedes aegypti 100%Disarankan kepada Dinas Kesehatan dan masyarakat menggunakan ikan Plati Pedang sebagai pemberantasan Vektor Aedes aegypti secara biologis melalui larvanya dan bagi penelitian lain perlu dilakukan penelitian lebih lanjut untuk mengetahu kecepatan daya predasi. Kata Kunci: daya predasi ikan cupang (Betta sp.), ikan plati pedang (xyphophorus Helleri), larva nyamuk Aedes aegypti.

Impacts of Environmental Changes on Health in the Gulf Region
Authors: Muhammad Hashim Ghouri  , Natasha Irfan  
Published: July 2020

From the mid-20th century, there has been quite a radical change in environmental and climate patterns regionally as well as globally. The reason behind these changes is primarily linked to deforestation, industrialization, expanded use of fossil fuels, and the extreme production of carbon dioxide (CO2) in the atmosphere. The environment comprises the surrounding conditions such as the complex of biological, physical, and chemical factors that act upon the ecological community and ultimately determine its form and survival. Environmental change encompasses the disturbances caused either by ecological processes or by the human influence which can be in the form of man-made disasters including but not limited to wars, oil spills, pollution, cyclones, etc. Environmental changes are a huge threat to humanity as a whole. These changes can be detrimental to health in a multitude of ways. Most significant ones being exacerbating existing health conditions or causing unforeseen health problems. These environmental changes affect human health by polluting the air we breathe, the water we drink, and the food that we eat. As a result of accelerated progressions in technology, active industrialization, ongoing wars, irrational use of pollutants like petroleum, etc., the whole of our planet is susceptible to environmental changes, but some areas like the Gulf region have been more sensitive to these.
The gulf has shown climate deviations that have transmuted into various environmental extremes such as rising sea levels, melting of the arctic ice caps, droughts, and floods. According to the widely cited, "The Stern Review", a temperature rise of 2 degrees Celsius will see a 20-30% decrease in water availability in one of the regions of the globe, and a 4 Celsius rise will result in up to 50% decrease in water availability1. The latest example of this is Kuwait; where due to the environmental changes world's most scorching day was recorded recently in 20192.The Gulf region is the largest producer of oil and gas in the world fulfilling 1/3rd of the world’s needs. According to world bank statistics, UAE, Saudi Arab, and Qatar produce around 22.9, 19.4 & 43.9 metric tons of CO2 per capita against the global average of 5.0 metric tons of CO2 per capita. These materials when processed to make electricity and other products release greenhouse gasses which are highly susceptible to environmental changes that have a direct or indirect effect on the health in the region. The byproducts include particulate matter (PM2.5) that cause chronic respiratory diseases and also aggravate the asthma condition in many. Furthermore, the overall increase in urban smog also has an impact on the psychological health of a human being by making the environment dark and hazy.
A Pilot Study on Thickened Blood Vessels in Endometrial Curettage in Dysfunctional Uterine Bleeding
Authors: Zunaira Javed  , Gulshan Ayesha  , Samina Badar  
Published: July 2020

Background: Dysfunctional uterine bleeding (DUB) is a common disease. About 10% of patients registered with DUB in Gynecology OPD for treatment in developing countries. There has been a change in the rhythmic cyclic menstruation that causes excessive and irregular bleeding. Lack of ovulation or oligo-ovulation leads to permanent estrogenic effects without opposing the progesterone effects. Other causes of the estrogen domain may have similar effects. The relative estrogen domain causes several changes in the uterine vascular system that causes menstrual bleeding.
Objective: To determine the frequency and significance of thickened blood vessels in curettage of the endometrium in dysfunctional uterine bleeding.
Materials and methods: It was a Retrospective cross-sectional pilot study conducted at Department of Gynecology and Obstetrics, Jinnah Hospital Lahore for one-year duration from January 2017 to December 2017.Hematoxylin and eosin (H&E) stained sections 30 consecutive incident cases of endometrial curettage due to dysfunctional uterine bleeding were examined by an optical microscope, with particular regard to the number of thickened blood vessels. All patients with history of endometrial curettage with dysfunctional uterine bleeding were included while curettage of uterine mucosa in patients with a specific etiology, such as endometritis, atypical hypertrophy, retained products, intrauterine devices (intrauterine device) were excluded.
Results: Over 50% of patients were perimenopausal, i.e. 40-55 years of age. All endometrial procedures included thickened blood vessels. On average, there were about 8 blood vessels thickened by curettage of the endometrium.
Conclusion: Estrogen-induced vascular lesions result in greater permeability, which can lead to the accumulation of various plasma proteins with increased intramural vascular thickening. These thickened veins may not contract properly, causing excessive bleeding and prolongation.
