Machine Learning Prediction of Response towards Anti-VEGF Injections in Patients with DME: Prediction of Post-Injection CST

Diabetic macular edema (DME) has become one of the most potential complications that results in loss of vision in patients with diabetic retinopathy. Treatment outcomes that have been predicted directly with advent of machine learning (ML) methods after the initial anti-vascular endothelial growth factor (anti-VEGF) injection, has become extremely vital in the management of DME. Purpose: The aim of this study is to analyze the efficiency of the ML regression models which were developed and validated to predict the possible post-injection central subfield thickness (CST) value and distant vision best corrected visual acuity (DV BCVA) in eyes with DME before the anti-VEGF injection is administered at either treatment initiation or during treatment monitoring. Methods: This retrospective study was conducted in Medical Research Foundation, Chennai, India from January 2010 to December 2020. The model development emphasized on an ensemble ML system consisting of four ML models that were developed and trained independently using the clinical parameters to predict the post injection CST value. The dataset consisting of 906 patients with total of 1874 samples [Optical coherence tomography (OCT) images and clinical parameters] were divided into trained and test set, and the model was validated on test dataset. The predicted CST values was then compared against the respective sample’s post injection actual CST value. The comparative results were measured in terms of Correlation Coefficient and Mean Absolute Relative Error (MARE). Results: On evaluation, we found that Support Vector Regression (SVR) with linear kernel performed best among the other models with four different scenarios in term of both CST and DVBCVA prediction with correlation coefficient of 0.65, 0.73, 0.75, 0.85 and 0.83, 0.87, 0.89 and 0.92 respectively.

Leptin Receptor Gene Variant Rs1137101 and Ghrelin Gene Variant Rs696217 are Associated with Body Mass Index in Brazilian Population: A Case-Control Study

Introduction: Obesity is a multifactorial condition influenced by environment and genetic factors. Controlling appetite and satiety involves complex interactions between the hypothalamus, which is responsible for homeostasis regulation energy, and hormones that regulate appetite including leptin and ghrelin. Leptin plays an important role in the regulation of food intake and energy expenditure, generating an increase in energy burning and decreasing food intake. And ghrelin is directly involved in the regulation of short-term energy balance. Objectives: To verify frequency, biochemical profile and Body Mass Index (BMI) variations according to SNPs in LEPR and GHRL gene. Subjects and Methods: 163 both genders subjects were classified into Study Group (SG): 103 subjects with obesity; Control Group (CG): 60 non-obese. Blood samples were collected to perform DNA extraction and biochemical profile analysis. Statistical significance was established at p < 0.05. Results: The genotype and allele frequency were similar between groups for both polymorphisms. The _/A genotype of the GHRL rs696217 polymorphism was associated to increased BMI in SG compared CG (p = 0.003) and increased triglycerides (TG) and very low density lipoprotein (VLDLc) values in CG (p < 0, 05). The _/A genotype was also associated with increased fasting glucose compared to CC genotype only in CG (p = 0.031). Considering the LEPR rs1137101 polymorphism, AA genotype subjects presented higher BMI compared to _/G genotype subjects (p = 0.024). No difference between biochemical profile variables related to LEPR rs1137101 polymorphism was found. Conclusion: AA genotypes of the LEPR rs1137101 polymorphism and _/A of the GHRL rs696217 polymorphism suggest being risk factors for BMI and the latter is associated with fasting glucose, VLDLc and TG variation.

Association of Viruses with Aplastic Anemia: A Case Control Study

Several viruses are often believed to be associated with acquired aplastic anemia. There is paucity of literature proving the association between viruses and aplastic anemia. We aimed to study the association of aplastic anemia with Human Parvovirus B19 (B19V), Epstein Barr virus (EBV), Cytomegalovirus (CMV), Hepatitis viruses, Measles virus (MV), Varicella Zoster virus (VZV) and Adenovirus (AdV). Between January 2020 to December 2020, confirmed cases of aplastic anemia and age and sex matched controls of iron deficiency anemia were enrolled in the study. They were tested for the above- mentioned viruses for antigen and/or IgM antibody by ELISA and/or nucleic acid by Real Time PCR in serum samples. Relevant history was collected. Cases were followed up at 3, 6 and 12 months after enrollment for recording the outcome. Total 68 cases and 34 controls were included in the study of which 61(89.70%) cases and 12(38.23%) controls were positive for markers of at-least one of the 10 viruses studied. B19V, EBV, CMV and Hepatitis B virus were found to be significantly associated with aplastic anemia. Five patients died within 12 months. Mortality was not associated with viral infections. Viral infections may play a role in pathogenesis of acquired aplastic anemia.

Level of Adherence to Antiretroviral Therapy Among People Living with HIV/AIDS in Ekiti State

Introduction: The use of anti-retroviral drugs slows down disease progression in Human Immunodeficiency Virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS) and this has improved the quality of life and life expectancy of Persons Living with HIV/AIDS (PLWHA). However, optimum use of antiretroviral drugs (adherence) by PLWHA is the key to achieving viral load suppression and preventing drug resistance in them. Objective: This study determined the level of adherence to Anti-Retroviral Therapy (ART) among PLWHA in Ekiti State. Methodology: A cross-sectional study was conducted on 320 PLWHA in Ekiti State University Teaching Hospital, Ado-Ekiti and 300 PLWHA in Federal Teaching Hospital, Ido-Ekiti aged 18 years and above using ARV for at least six months prior to the study. Quantitative data were collected from the participants using a structured questionnaire while sixteen in-depth interviews were conducted among purposively selected PLWHA in both study centres to further elicit qualitative information on determinants of adherence. Quantitative data were analyzed with SPSS 22 using descriptive statistics while content analysis was used for qualitative data. Regression analysis was done to identify determinants of adherence at p value < 0.05. Results: About 60% of the PLWHA had high level of ART adherence while 18.9% had low adherence. Most of the respondents were female (66.0%), married (76.1%) and Christians (89.4%) and had post-secondary education (43.4%). Respondents’ age (X2=32.483), educational status (X2=2.473), marital status (X2=40.083), occupation (X2=57.951) and distance from the clinic (X2=13.181) significantly influenced the level of adherence. Patient factors such as forget timing of the medication, pill burden and feeling better, psychosocial factors like stigmatization, non-disclosure of status and depression; and healthcare factors such as long clinic waiting time and absence of support are some of the barriers to optimum ART adherence. Conclusion: Counseling on drug adherence and psycho-social support to PLWHA will further improve their level of adherence to medication.

Isolation of Microorganisms Associated with Palm Oil Contaminated Soil

Aim: Palm oil processing generally generates lots of wastewater (palm oil mill effluent), this is usually discharged into the environment in the untreated form and subsequently causes several environmental issues. There is therefore need to isolate microorganisms that can be used to clean up the palm oil contaminated environment especially the soil. Methods and Results: Palm oil contaminated soil was obtained from Oba Adeyemi palm oil mill in Oyo, Oyo State, Nigeria, other soil samples which were purposely contaminated with palm oil, were obtained from Ajayi Crowther University Oyo, Oyo State. Isolation, characterization and identification of microorganisms were carried out using morphological and biochemical characterization. The isolates were preliminarily screened for lipolytic activities, this was confirmed by growth on the mineral salt medium after 7 days, signifying hydrolysis. One of the prominent isolates was further identified by sequences analysis of 16S rRNA genes. Forty-one bacterial isolates were identified, which included species of Bacillus (80 %), Pseudomonas (20 %) in the oil mill contaminated soil sample and Bacillus spp. (100 %) in the purposely contaminated soils. Twenty-nine fungal isolates including species of Aspergillus, Oidiodendron, Geotrichum, Penicillum, Saccharomyces were isolated with Aspergillus fumigatus having the highest frequency of occurrence (37.5 %) in artificially contaminated soil and Saccharomyces spp. having the highest frequency of occurrence (91 %) in palm oil contaminated soil from the palm oil mill. Sequencing of the 16S rRNA of one of the prominent isolates showed that it was identified as MN607220 Saccharomyces cerevisae. All the bacterial and fungal isolates had lipolytic activities except Bacillus mycoides and Oidiodendron sp. respectively. Nine of the ten Saccharomyces sp. had lipolytic activities. Conclusion: These screened organisms could therefore be employed for the cleanup of palm oil contamination in the environment. Significance and Impact of Study: Thereby ridding the environment of possible toxic effects especially in areas of need like Malaysia

Evaluation of Characterization Results of Ru, Sb And V_Doped Sno2 Coatings Deposited by Using Produced and Commercial Targets

Ruthenium, Antimony and Vanadium doped and undoped tin oxide (SnO2) thin films were prepared by the R.F. Sputtering method. At the beginning of the thin film production studies, pellets were formed by pressing the filled and undoped tin oxide powders in the laboratory environment. The purpose of creating these pellets is to replace commercially purchased target material that acts as the coating material in the sputter coating device. The aim of the study is to use these pellets instead of this commercial target due to its disadvantages such as long lead time and expensiveness, and thus to produce easier, more diverse and high quality thin films. This study includes the synthesis of pure and doped thin films of tin oxide semiconductor material, which has a wide band gap and attracts attention with its wide spread use thanks to this feature, subjecting it to annealing process under different temperatures and times, and structural and morphological characterization studies: XRD, SEM, AFM, XPS, UV-Vis Spectrophotometer and Nano-hardness machine. The study showed that doped and undoped tin oxide films showed similar properties to similar studies seen in the literature, so that the pellets formed in the laboratory environment functioned. No major structural difference was observed in the films produced as a result of the use of pellets and target. As a result of the findings of the study, it has been seen that it is a preliminary study for the investigation of gas sensing properties.

Mattress Coil Spring Fatigue and Support: A Potential Association with Spine Stiffness and Pain

Prolong mattress use compresses the metal coil springs which may ultimately result in a compromised sleeping surface. This coil spring metal fatigue can result in spinal pain and stiffness. The purpose of this study was to compare the amount of metal fatigue of used mattress coil springs from the areas bearing greatest body weight versus areas subjected to little compression to ascertain the. Six weight bearing coil springs (WBS) were extracted from the center the used (range 8-10 yr.) mattresses (N=32) and six non-weight bearing coil springs (NWBS) were extracted from the head/foot are of the same mattresses. To determine spring weakness a special frame and platform was constructed to compare unloaded spring height with compression distance height following placement of a 1,296 g ingot on the platform. Also, a pressure gauge was used to measure the amount of pressure required to compress the coil springs a distance of 2 cm. Comparison between WBS and NWBS data were statistically treated using independent t-tests and a one-way ANOVA. There were no significant group differences in weight or height in unloaded coils. However, there were significant (p<0.05) differences in coil spring compression distance under load (WBS = 2.78 ± 0.34 cm; NWBS = 1.52 ± 0.39 cm) and force gauge compression (WBS = 1090.51 ± 88.42 g; NWBS = 1213.12 ± 71.38 g) between groups. While manufacturers’ recommendations to replace a mattress is ranges between 8 and 10 yrs., these results indicate that coil spring weakness may occur before 8 yrs. of use. Weak springs leads to loss of weight bearing capacity of the mattress thereby resulting in sagging upon use. Such sagging which may compromise sleep posture with accompanying back pain and poor sleep quality and quantity.

Hierarchical Analysis of The Factors Associated with the Consumption of Fruits and Vegetables: Cohort of Universities of Minas Gerais, Brazil (Cume Project)

The objective of this study was to assess which factors, at hierarchical levels, are associated with adequate consumption of fruits and vegetables (FV) in undergraduate and graduate students. This is a cross-sectional analysis of the baseline of the Cohort of Universities of Minas Gerais (CUME Project), with alumni from Universities of Minas Gerais, Brazil, in the years 2016 and 2018. The outcome variable was adequate consumption of FV (≥400 g/day). The exposure variables were divided into: block 1, socioeconomic (marital status, education, professional status, individual and family income); block 2, behavioral (physical activity, alcohol consumption, tobacco use, and consumption of legumes, natural juices, ultra-processed foods, soft drinks and industrialized juices, and fast foods); block 3, individual (gender, age, skin color, self-perception of health and presence of obesity, systemic arterial hypertension, diabetes mellitus, and depression). To verify the associations, hierarchical multiple logistic regression was used. The sample consisted of 4,124 individuals with a median age of 34 years and Interquartile Range (IQ) of 12 years, 68.1% women, with a high frequency (62.2%) of adequate consumption of FV. This adequate consumption of FV was associated with being a woman (OR=1.41; 95%CI 1.21-1.64; p<0.001), advancing in age and being physically active (OR=2.10; 95%CI 1.78-2.47; p<0.001), having regular consumption of natural fruit juice (OR=2.00; 95%CI 1.70-2.34, p<0.001), or consumption of ultra-processed foods (OR=0.96; 95%CI 0.95-0.97; p<0.001). In conclusion, individual and behavioral factors are associated with adequate consumption of FV in highly educated individuals.

Effects of Gabapentin Enacarbil on Cortical Arousals, Heart Rate, Blood Pressure and Anterior Tibialis EMG Responses Associated with PLMs in Restless Legs Syndrome

Objective: This study was conducted to investigate the effects of gabapentin enacarbil (GEn) on sleep EEG, heart rate (HR), blood presssure, anterior tibialis EMG activity (PLMs power) and subjective complaints in subjects with moderate to severe RLS and disturbed sleep. Methods: This was a single site, single-blind, placebo run-in, fixed dose single group polysomnography (PSG) study. Eligible subjects (age 24-66 years) were treated with placebo for one week and GEn (600 mg/day) for 4 weeks. Two in-laboratory PSGs were collected for adaptation and baseline at the end of the placebo run-in period and for re-adaptation and efficacy assessment at the end of the 4-week treatment period. The primary endpoint was the difference in PSG derived cortical arousal intensity (arousal scale, 0-9) associated with PLMs between 4 weeks of treatment with GEn and placebo. Secondary endpoints included changes in HR responses (ΔHR), nocturnal systolic blood pressure (SBP) changes (>10 mmHg) secondary to PLMs and PLMs power. Other PSG and subjective measures were assessed. Results: Of 20 subjects enrolled, 18 completed the study. Subjects treated with GEn did not show significant improvements in cortical arousal intensity and ΔHR. However, subjects showed reduced PLMs power (p= 0.013) and associated reductions in nocturnal SBP per hour of sleep (p= 0.041) GEn showed significant improvement in other PSG parameters and subjective endpoints. Conclusion: The data suggests that GEn reduces the frequency and power of PLMs and the corresponding SBP changes in subjects with RLS. Despite reducing the total number of PLM associated arousals and nocturnal HR, the study did not demonstrate consistent effects of GEn on cortical arousal intensity and corresponding HR changes associated with PLMs. Clinical Trial Registration: identifier: NCT02424695

Benefits and Health Risks Associated with Energy Booster Drinks: A Review Study

There are several energy drinks available in the market such as Red Bull, Sting, Rebound, Power Up! Triple X Energy Drink, and so on. After the Red Bull drink was introduced in the market in1990s, Energy drinks started to gain popularity and afterwards it became a common name especially among teenagers and young adults [1]. Most energy drinks are caffeinated nonindulgent beverages that are professed to give an additional increase in energy for day-by-day work, increase alertness, and improve athletic performance and mood. There are even certain shreds of evidence present to substantiate these claims, but the effects of these drinks on mental and physical health cannot be neglected. There are reports of adverse events such as insomnia, anxiety, cardiovascular events, seizures, tachycardia, type-2 diabetes, and even death are associated with the consumption of these drinks [2]. This review will focus on energy drinks, their ingredients, health risks associated with these drinks, and will also suggest some recommendations such as changes in marketing, providing education to children regarding adverse effects of these drinks, and further research should be carried out in this domain.

Anodizing for Design and Function

Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.
