Gender Identification and Classification of Drosophila melanogaster Flies Using Machine Learning Techniques

Drosophila melanogaster is an important genetic model organism used extensively in medical and biological studies. About 61% of known human genes have a recognizable match with the genetic code of Drosophila flies, and 50% of fly protein sequences have mammalian analogues. Recently, several investigations have been conducted in Drosophila to study the functions of specific genes exist in the central nervous system, heart, liver, and kidney. The outcomes of the research in Drosophila are also used as a unique tool to study human-related diseases. This article presents a novel automated system to classify the gender of Drosophila flies obtained through microscopic images (ventral view). The proposed system takes an image as input and converts it into grayscale illustration to extract the texture features from the image. Then, machine learning (ML) classifiers such as support vector machines (SVM), Naive Bayes (NB), and K-nearest neighbour (KNN) are used to classify the Drosophila as male or female. The proposed model is evaluated using the real microscopic image dataset, and the results show that the accuracy of the KNN is 90%, which is higher than the accuracy of the SVM classifier.

The end-of-life care in the emergency department setting with respect to the Middle East countries and comparison with the Western countries

Patients who are affected with severe chronic illness or in need for end-of-life care ((EOLC), they are mainly treated in the emergency departments (EDs) to provide the utmost amount of care for their condition. The major aspects which impact the accessibility of care in the ED include the clinical, social, and economic factors in different regions of countries. In recent years as the EOLC has been provided, it has been observed that patients experiencing EOL and dealing with a dying process do not always achieve the experience what resonates with a good death. The main cause of concern for these patients is the problem that in the ED they do not have access to palliative care options, mainly the ones who are suffering from noncancer ailments. These patients are provided palliative care at a very later stage in the ED when they could have been provided with palliative management at home in an earlier manner. EOLC plays a very critical role in ensuring that terminally ill patients are given a proper and adequate amount of care. The present article aims to highlight the EOLC in the ED in the Middle-Eastern regions. We aim to present a broader view that has impacted the current situation of EOLC in the Middle East regions and demonstrate a description of the EOLC in an ED setting between the Middle Eastern regions and western culture focusing on the following five important factors: Situation acceptance in the ED, cultural compatibility of bioethics, treatment perspective, skills among clinical providers and physician's attitude. In this literature review, we present the evidence associated with the EOLC in the ED setting with respect to the Middle East countries and bring out their differences in the religious, clinical, social, ethical, and economic aspects in comparison with the Western countries. We also tried to determine the differences between the two regions in terms of the principle of explaining the fatal diagnosis or poor prognosis, family relations, and do-not-resuscitate decision. This comparative analysis will help to bring out the gaps in the quality of care in the ED in the Middle East countries and promote the development of well-assessed policies and strategies to improve EOLC. The findings of this study and the future interventions that can be implemented to improve the structure and design of the EOLC that will act as a guiding force to execute evidence-based quality improvement program.

Evaluating Acute Testicular Pain Using Point-of-Care Hand-Held Doppler in the Emergency Department: A Prospective Pilot Study

Introduction Testicular pain is one of the common conditions in patients visiting the emergency department. The causes of acute testicular pain vary from non-urgent inflammatory conditions like epididymo-orchitis to testicular torsion which is a surgical emergency. Early diagnosis of testicular torsion with early initiation of appropriate surgical intervention helps in salvaging the testes. There is a need for a simple, rapid bedside diagnostic tool for the evaluation and triaging of subjects with acute testicular pain in the emergency department. The aim of this study is to determine whether hand-held Doppler (HHD) examination by the emergency department (ED) physician can safely rule out testicular torsion in a case of acute testicular pain. Materials and Methods A prospective pilot study was conducted in the emergency department of Alkhor Hospital, Hamad Medical Corporation, Qatar. The subjects between 18 to 50 years of age who presented to the ED with testicular pain were included. Subjects with recent trauma to the scrotum, or recent genitourinary surgery and those who had pain for more than 48 hours were excluded. Point-of-care HHD was done by a single ED physician who was blinded for the Doppler study results done by the radiologist. The results of the HHD performed by the ED physician and Doppler study performed by the radiologist were compared and analyzed. Results  Forty-five patients were included in the study. The mean age was 28 years and the mean duration of pain was 20 hours. HHD ruled out testicular torsion in 44 subjects with a specificity of 97.8%. In one subject, HHD was reported as torsion testis which was ruled out by the radiologist. The radiologist Doppler ruled out torsion in all 45 subjects. Conclusion The diagnostic performance of HHD by the ED physicians was almost equal to that of radiologists in ruling out testicular torsion. HHD can be used as a first-line triaging tool by the ED physician to rule out torsion of testis in patients presenting with acute testicular pain. We conclude that patients with testicular pain with a negative HHD for torsion testis can be safely discharged from the emergency department.
