IntroductionThe COVID-19 pandemic demonstrated the need for skilled medical practitioners in public health, and outbreak investigations. The College of Medicine and Health Sciences at the United Arab Emirates University (UAEU) introduced a clerkship in public health constituting theoretical and practical sessions to 5th year medical students in 2015. The aim of this study is to explore the satisfaction of the students with the public health clerkship which is crucial for the assessment and reformation of the taught curriculum.MethodsA cross-sectional, post-evaluation analysis was conducted from the period 2015–2022. The evaluation questionnaire was conducted via an online university system. The survey contained 5 themes: pre-course instructions, structure of the clerkship, academic staff, activities, and learning outcomes. Ethics approval was secured from the Social-IRB of the UAEU. We used SPSS version 26 to analyze the data using independent t-test and ANOVA.ResultsOne hundred and seventy four students (27.4% response rate) participated in the study. Overall, the students had an average satisfaction score of 2.86 out of 4. The majority of the students reported having a good understanding of public health (93.7%), improving their oral presentation skills (91.2%), and developing new skills (87.2%). Furthermore, more than 9 in 10 students (96.1%) reported that the program expanded their knowledge, skills, and confidence. The mass (90.2%) of students agreed that the clerkship content was covered in sufficient depth, majority of the students agreed that they had received enough information about the clerkship before it started (74.6%), majority of the students agreed that the faculty were interested in their personal development (86.1%) The students who completed the clerkship prior to the COVID-19 pandemic had a statistically significant (P = 0.02) higher average rating (72.8%) than students who completed the clerkship during the pandemic (71.1%).DiscussionMedical students at the UAEU were satisfied with the activities and delivery of the public health clerkship and found it rewarding. Conducting needs assessment and proposal writing provided them with the knowledge, skills, and confidence to conduct research in their career. These findings may be useful in helping and support other institutes to plan and develop a clerkship in the public health.
High-altitude vertical wind profile estimation using multirotor vehicles
Authors: McConville Alexander , Richardson Thomas 
Published: March 2023

Capturing vertical profiles of the atmosphere and measuring wind conditions can be of significant value for weather forecasting and pollution monitoring however, collecting such data can be limited by current approaches using balloon-based radiosondes and expensive ground-based sensors. Multirotor vehicles can be significantly affected by the local wind conditions, and due to their under-actuated nature, the response to the flow is visible in the changes in the orientation. From these changes in orientation, wind speed and direction estimates can be determined, allowing accurate estimation with no additional sensors. In this work, we expand on and improve this method of wind speed and direction estimation and incorporate corrections for climbing flight to improve estimation during vertical profiling. These corrections were validated against sonic anemometer data before being used to gather vertical profiles of the wind conditions around Volcan De Fuego in Guatemala up to altitudes of 3000 m Above Ground Level (AGL). From the results of this work, we show we can improve the accuracy of multirotor wind estimation in vertical profiling through our improved model and some of the practical limitations of radiosondes that can be overcome through the use of UAS in this application.

Published: March 2023

IntroductionCopoazú seed butter [Theobroma grandiflorum (Wild ex Spreng) K. Schum] is a rich source of fatty acids and polyphenols, active substances with high antioxidant and moisturizing activities with potential applications in the cosmetic industry. Some studies have demonstrated that sun-induced skin damage is partially mediated by oxidative pathways; in fact, there is evidence for the photoprotective roles of antioxidants.MethodsWe have developed a stable emulgel-type cosmetic formulation using Copoazú seed butter at different concentrations of 5, 10, and 20% and examined the antioxidant activity and the effect of Copoazú seed butter emulgels against UV-induced epidermal damage in mice to verify its use for topical photoprotective products.Results and discussionThe antioxidant activity expressed as EC50 values varied from 8.47 ± 0.013 mg/ml to 4.53 ± 0.046 mg/ml for Copoazú seed butter emulgels. In vitro sun protection factor (SPF) assessment showed that Copoazú seed butter emulgel at 20% has the highest SPF of 11.67 ± 0.001, which is acceptable for the sunscreen products development, and these results were corroborated by the in vivo results since the mice were irradiated with UV light and treated with Copoazú seed emulgels and showed minor damage or significantly reduced the severity of the damage and were comparable with the standard photo-protector. The results showed that Copoazú seed butter is a promising compound for photoprotective formulations.

BackgroundEquine coronavirus (ECoV) leads to outbreaks with variable morbidity and mortality. Few previous reports of risk factors for infection are available in the literature.ObjectivesTo describe unique clinical findings and risk factors for infection and development of clinical disease.Animals135 horses on a farm affected by ECoV outbreak.MethodsRetrospective cohort study. Data obtained included age, breed, gender, activity level, housing, and feed at the onset of the outbreak. Factors were evaluated for assessment of risk of infection using simple logistic regression or Fisher's exact test. Significance was set atp≤ 0.05.Results and findingsForty-three of 54 (79.6%) horses tested on the farm were positive on fecal PCR for ECoV, and 17 horses (12.6%) developed clinical signs consistent with ECoV. Out of 17 horses in which the presence or absence of signs of colic was noted, 6 of 17 (35.3%) showed signs of colic. Three of these horses had small colon impactions, 2 of which required surgical intervention. Significant risk factors for having positive PCR results included being primarily stalled (OR 167.1, 95% CI 26.4–1719), housing next to a positive horse (OR 7.5, 95% CI 3.1–19.0), being in work (OR 26.9, 95% CI 4.6–281.9), being fed rationed hay vs.ad libitum(OR 1,558, 95% CI 130.8–15,593), and being fed alfalfa hay (OR 1,558, 95% CI 130.8–15,593).Conclusions and clinical importanceThis report describes risk factors for ECoV infection many of which were associated with intensive management of show horses. Clinicians should be aware that clinical signs vary and can include severe colic.

Published: March 2023

BackgroundParoxysmal gluten-sensitive dyskinesia is a subtype of movement disorder classified as canine paroxysmal dyskinesia (cPD), which until now has only been described in Border Terriers (BT).ObjectivesOur aim was to report cPD with positive gluten serology in dog breeds other than BT.AnimalsThirty-one client-owned dogs with suspected cPD were examined in this study.MethodsThe hospital records of the dogs where the serum was tested for modified gliadin peptide immunoglobulin G (gliadin IgG) and tissue transglutaminase-2 immunoglobulin A (transglutaminase-2 IgA) were studied. A total of 31 dogs were presented to the clinic with cPD. A work-up consistent with Tier 1 or Tier 2 confidence levels for canine epilepsy was undertaken in all dogs. The dogs' diets and episode descriptions or videos in 16/31 cases were additionally studied. A follow-up was held to inquire about the dogs' wellbeing and response to the diet changes.ResultsFourteen of the 31 dogs tested positive for gluten sensitivity with either gliadin IgG or transglutaminase-2 IgA or both ratios elevated. In seven dogs, serology was classified as questionable with gliadin IgG or transglutaminase ratios mildly elevated. Ten dogs tested negative. According to the owners' reports, five of the dogs that tested positive had no more episodes after changing to a strictly gluten-free diet, with one of the dogs relapsing twice after being fed treats containing gluten. Three dogs had a reduction in episode frequency of &gt;50%, and two dogs had shorter and less intense episodes.ConclusionA considerable subset of dog breeds presented for presumed cPD showed laboratory signs of gluten sensitivity and responded to a gluten-free diet.
A High Throughput BFV-Encryption-Based Secure Comparison Protocol
Authors: Kuo Tzu-Hsiang , Wu Ja-Ling 
Published: March 2023

Secure comparison is a fundamental problem in multiparty computation. There are two different parties, each holding an l-bit integer, denoted by a and b, respectively. The goal of secure comparison is to compute the order relationship between a and b, say (a>b)∈{0,1}, without revealing their inputs to any others. Since previous solutions based on homomorphic encryption need at least Ω(l) encryptions for each l-bit comparison, the total encryption time leads to a computational bottleneck for these protocols. This work presents a fast, semi-honest, secure comparison protocol based on the BFV encryption scheme. With its vector-like plaintext space, the number of required encryptions can be significantly reduced; actually, only six encryptions are needed for each comparison in our protocol. In other words, the proposed protocol can achieve the time complexity O˜(λ+l) for a given security parameter λ. As a result, 4096-bit integers can be securely compared within 12.08 ms, which is 280 times faster than the state-of-the-art homomorphic encryption-based secure comparison protocol. Furthermore, we can compare k pairs of l⋅k−1-bit integers with almost the same execution time as comparing l-bit integers and achieve higher throughput regardless of the compared integer size.

Authors: Hara Kaisei , Mori Shohei , Arakawa Mototaka , Kanai Hiroshi 
Published: March 2023

Abstract
Improving the accuracy of heart wall motion measurement is essential to realise better cardiac function evaluation. This paper proposed a two-dimensional (2D) displacement estimation method with a high temporal resolution using the 2D complex cross-correlation of element RF signals of an ultrasonic probe between frames returned from the target scatterers. The application of the proposed method to the phantom displacement confirmed its principle. The estimated 2D displacement of the phantom was consistent with the set displacement. Subsequently, the method was applied to two healthy subjects to measure the 2D displacement of the interventricular septum during one cardiac cycle. Consequently, during systole and diastole, the movement of the myocardium was measured, and the results were validated.

BALANCE DEL MODELO DE COMBATE A LA CORRUPCIÓN EN MÉXICO
Authors: Altamirano Castro José Guadalupe , López Gaytán Martha Patricia 
Published: March 2023

El artículo busca mostrar un acercamiento al estado que guarda el problema de la corrupción en México, así como la comprensión del modelo actual de combate a la corrupción y la incidencia que ha tenido este a partir de la reforma constitucional de 2015 donde justamente se agrega como sello principal, el involucramiento ciudadano. Si bien, hasta ahora, se han realizado múltiples esfuerzos desde el gobierno y la sociedad civil para tratar de frenar y revertir este problema que le ha causado a México un gran costo social, económico e institucional, tal parece que la semilla sembrada no ha dado los frutos esperados. Desgraciadamente, podemos concluir que muchos de esos esfuerzos, sobre todo los que corresponden al poder político, se han instrumentado solo como formas de justificar el poder y han carecido de dos ingredientes fundamentales: la participación ciudadana y la voluntad política. En lo que, sí se ha avanzado, es en el trabajo que, desde las organizaciones sociales, académicas y de comunicación, se ha llevado a cabo para analizar, proponer y visibilizar el problema, lo que, sin duda, obliga a la autoridad a actuar y rendir cuentas.

Comparison of Accuracy Scores between CLOC and RSCLO Scoring Systems in Predicting the Risk of Preoperative Laparoscopic Cholecystectomy Conversion at Dr. Hasan Sadikin General Hospital, Bandung, Indonesia
Authors: Nurhayat Usman  , Bambang Am Am Sulthana  , Adiguna Reza Syahrial 
Published: March 2023

Background: Cholecystectomy is a surgical therapy for cholelithiasis which can be performed by open cholecystectomy or laparoscopic cholecystectomy. Not all laparoscopic cholecystectomy procedures work properly. Sometimes it requires conversion from laparoscopic cholecystectomy to open cholecystectomy. A risk factor scoring system has been developed and validated using a large prospective cholecystectomy database and can accurately predict the likelihood of conversion with the conversion from laparoscopic to open cholecystectomy (CLOC) score and risk score for conversion from laparoscopic to open cholecystectomy (RSCLO). This study aimed to compare the accuracy value between CLOC and RSCLO in predicting the risk of preoperative laparoscopic cholecystectomy conversion at Dr. Hasan Sadikin General Hospital, Bandung, Indonesia.
Methods: This study was an observational study with a cross-sectional approach. A total of 183 research subjects participated in this study. Observation of CLOC and RSCLO scores was carried out in this study. Univariate and bivariate data analysis was carried out using SPSS. The analysis of the value of sensitivity, specificity, positive predictive value, and negative predictive value were carried out using Medcalc software.
Results: A CLOC score > 5.5 has a greater conversion risk than a CLOC score ≤ 5.5. Meanwhile, an RSCLO score >-2 has a greater conversion risk than an RSCLO score ≤ -2. Sensitivity value CLOC for the prediction of preoperative conversion from laparoscopic cholecystectomy to open cholecystectomy obtained 75% and a specificity of 74.85%, with value negative predictive value, which is higher than a positive predictive value and 74.86% accuracy. The sensitivity value RSCLO for the prediction of preoperative conversion from laparoscopic cholecystectomy to open cholecystectomy was obtained at 75% and a specificity of 77.78%. With value negative predictive value, which is higher than the positive predictive value and 74.86% accuracy.
Conclusion: The CLOC and RSCLO scores were equally accurate in predicting preoperative conversion from laparoscopic cholecystectomy to open cholecystectomy.
