How to Keep Both the Consultant and the Local Veterinarian Involved
Authors: Schwenka Doug
Published: March 2023

Traditionally local veterinarians have been thought of as individual animal health care providers. As times change and as economic efficiency becomes more important the local veterinarian needs to focus on becoming more involved in the overall management of the operation and balancing what is best for the cattle and the owner.
Field Measurement of Milking Vacuum Using Flow Simulation
Authors: Stewart Steven
Published: March 2023

Many dairy veterinarians offer milking equipment evaluation to their clients as part of their routine services. While these services have usually been initiated largely for mastitis control reasons, improving milking performance is becoming a more important (and marketable) justification for these services, especially as dairies grow larger. Milking performance can be improved with proper vacuum settings and proper equipment configurations.

Much progress has been made in the past few years to simplify equipment evaluation and to clarify the analysis of the results. This paper discusses the routine field use of an artificial, portable flow simulator to measure claw outlet vacuum.9,10
Comparison of Two Estrus Synchronization Programs in a Large, Confinement-Housed Dairy Herd
Authors: Britt Jenks Swann , Gaska Jerome
Published: March 2023

Estrus synchronization programs have been used to manage reproduction in dairy cattle for many years. These programs involve various protocols for administration of a single hormone or combinations of hormones, but results have varied among programs and herds. Several synchronization programs use injections of prostaglandin F2a (PGF2a).1-3 A commonly used PGF2a program includes per rectal palpation to identify a corpus luteum (CL). Cattle with a CL are injected with PGF2a, observed for estrus, and inseminated only after estrus is detected. This program depends on the palpator's ability to detect a prostaglandin-receptive CL and may not be the most effective way to evaluate CL activity. Other programs that use PGF2a include the administration of 2 injections of PGF2a at selected intervals (usually 12 to 14 days) and insemination at a predetermined time or after cattle are detected in estrus. Both of these programs have resulted in the highest conception rates when cattle were inseminated after being detected in estrus, rather than inseminating at a predetermined time without detection of estrus.4

A new ovulation synchronization program5-11 does not require estrus detection. This program (Ovsynch) uses gonadotropin-releasing hormone (GnRH) and PGF2a to synchronize ovulation, which may not be accompanied by detectable signs of estrus. In the Ovsynch program, an initial dose of GnRH is used to synchronize waves of follicles and PGF2a is used to lyse the CL in groups of cattle and synchronize estrus. A second injection of GnRH induces ovulation of the dominant follicle in 85 to 95% of the synchronized cattle.5

Pregnancy rates often drop during seasons with high ambient temperature.7 This may be related to heat stress, rather than problems with estrus or ovulation synchronization, because conception rates typically decrease during periods with high ambient temperature.12

Surgical resection of umbilical structures in calves is most frequently done using intravenous or intramuscular administration of xylazine/ketamine with or without inhalation anesthetic agents. We were interested in examining the efficacy of a practical and inexpensive alternative anesthetic protocol for umbilical surgery, specifically intramuscular xylazine sedation combined with lumbosacral epidural administration of lidocaine and xylazine.
Clinical Use of Reproductive Tract Scoring To Predict Pregnancy Outcome
Authors: Pence Mel , BreDahl Russ
Published: March 2023

The relative economic importance of reproductive traits to the beef industry is estimated at twice the importance of beef production traits and four times the importance of product traits.1 The selection and management of replacement heifers influence the reproductive efficiency of the cattle industry.2 Heifers that mature early are capable of being bred earlier in a controlled breeding season and will wean a heavier calf.3 These heifers tend to breed early each breeding season for the rest of their reproductive life and have a lifetime heavier weaned calf weight.4 With this economic value placed on reproduction, ways to measure and predict reproductive efficiency in cattle are needed. One method to estimate reproductive efficiency was developed by researchers at Colorado State University.5 A reproductive tract scoring (RTS) system was developed as an indirect determination of age at puberty.

Authors: Paré J. , Cornaglia E. , Lallier R.
Published: March 2023

Rotavirus is an important cause of diarrhea in newborn cattle. The rotaviruses involved are typically of group A, and cause diarrhea in calves 4 to 14 days old. The isolation of rotaviruses has been reported in 44% of diarrheic calves and in 14% of healthy calves. The prevalence of rotavirus excretion has not been estimated in Quebec dairy calves. The objectives of this study were 1) to estimate prevalence of rotaviruses in feces of neonatal dairy calves, and 2) to compare 3 tests for detection of rotaviruses in fecal samples.
Impact of the board of directors’ characteristics on firm performance: A case of Bahraini listed firms
Authors: Al-Absy Mujeeb , Hasan Mustafa
Published: March 2023

This study aims to examine the impact of the characteristics of the board of directors (BOD), namely board independence, board size, frequency of board meetings, and board gender diversity, on firm performance. This quantitative study uses data from all firms listed in the Bahrain Bourse for 2019 and 2020. Data on BODs were taken from the companies’ governance reports, while data on firm performance, namely return on assets (ROA), return on equity (ROE), and earnings per share (EPS), were taken from annual reports. Based on the ordinary least squares (OLS) approach, the results show insignificant relationships between BOD characteristics and firm performance. Board independence, size, frequency of meetings, and gender diversity insignificantly enhance Bahraini firms’ performance. The results indicate that firms may need to effectively implement BOD mechanisms. Moreover, other factors may moderate the impact of BOD mechanisms on firm performance. Hence, the study suggests a need for more regulations and policies to increase the effectiveness of board members. This study alerts policymakers, firms’ shareholders and stakeholders, and researchers to the need to increase directors’ roles in boosting company performance, especially in developing countries, where it is complicated to force business to follow best governance practices.

Published: March 2023

La investigación tiene como objetivo relacionar las características de la capacidad de gestión y organización de la universidad peruana con el nivel de inclusión educativa de estudiantes con discapacidad auditiva. Se empleó un diseño correlacional-transversal y se efectuó un análisis estadístico descriptivo e inferencial de los resultados del cuestionario Evaluación del Entorno Educativo Inclusivo (3E+I), el cual fue aplicado a una muestra aleatoria de dos grupos de estudiantes (un grupo con discapacidad y otro sin discapacidad). El instrumento se validó mediante una prueba piloto previa cuyo índice de fiabilidad Alfa de Cronbach fue de 0,920. Los resultados mostraron correlación negativa inversa entre las percepciones de los conglomerados. También, los estudiantes con discapacidad auditiva identificaron una menor prevalencia de inclusión educativa en la universidad en relación con los estudiantes no discapacitados. El principal factor causal de dicha situación en la universidad es una débil función organizativa y formativa de estrategias para mejorar el desarrollo de la competencia sociocultural de los estudiantes en general. En este estudio, se concluye que la universidad peruana no realiza una gestión eficaz de inclusión educativa de los estudiantes con discapacidad auditiva, debido a la falta de organización e implementación de procedimientos de intervención dirigidos a personas con discapacidad como la auditiva.
The Effect and Mechanism of Sancao Lichang Decoction on Diarrhea-
Predominant Irritable Bowel Syndrome by Regulating Tlr4/Myd88/Nf-Κb
Pathway
Authors: Zhang Peng , Ma Ying , Wang Zheng , Tang Decai
Published: March 2023

Objective:

To evaluate the effect of Sancao Lichang decoction as traditional Chinese
medicine on diarrhea-predominant irritable bowel syndrome (IBS-D) and TLR4/MyD88/NF-κB
pathway.

Background:

Traditional Chinese medicine has made significant progress in preventing and treating
irritable bowel syndrome, and its efficacy has been validated by clinical practice. Sancao
Lichang decoction is an empirical prescription developed by professor Tang Decai that has been
used for many years to treat chronic diarrhoea with good curative effec. Still, its mechanism of action
on IBS-D is unknown.

Methods:

The study sample of Fifty SD rats was randomly divided into a blank group, model
group, low-dose group, medium-dose group, and high-dose group (n = 10). The IBS-D rat models
were established by restraining stress method and acetic acid enema. After different treatments,
defecation frequency, fecal water content (FWC), serum IL-6 and TNF-α contents, and protein level
of TLR4/MyD88/NF-κB in colon tissues were detected separately.

Results:

The indexes of rats in each group were significantly different. The increase in body
weight in the medium-dose and high-dose groups was significantly higher than that in the model
group (p < 0.05). Compared with the model group, the medium and high dose groups had lower diarrhea
frequency, FWC, interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α) (p < 0.05).
The expression levels of TLR4, MyD88, and NF-κB protein in the colon of the three groups treated
with Sancao-Lichan decoction were significantly lower than those in the model group (p < 0.01).
After different treatments, the colonic mucosa of rats in each group was stained with HE, which
proved that the structural damage of colonic mucosa was improved after treatment with Sancao
Lichang decoction, and the improvement effect was dose-dependent.

Conclusion:

Sancao Lichang decoction may reduce IBS-D by inhibiting TLR4/MyD88/NF-κB
pathway, inhibiting the inflammatory response, and improving intestinal mucosal barrier function.

Von Willebrand Factor and Intima-Media Thickness in Patients With Rheumatoid Arthritis: A Cross-Sectional Study
Authors: Fedorovych Khristina , Yatsyshyn Roman
Published: March 2023

Background. Cardiovascular risk assessment in patients with rheumatoid arthritis (RA) is often a real challenge and requires the search for new indicators to reveal the potential threat of developing atherosclerotic vascular lesions in the early stages.
The study aimed to analyse the association between von Willebrand factor (vWF), disease activity, and intima-media thickness (IMT) score in RA patients.
Materials and Methods. The study involved 60 RA patients divided into three groups based on the Disease Activity Score 28 (DAS-28) activity index and 20 individuals as healthy controls. Clinical and laboratory assessments included determining the number of swollen (SJ) and painful joints (PJ), the visual analogue scale (VAS) score, the erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and fibrinogen. The concentration of vWF in blood plasma was determined by an enzyme-linked immunosorbent assay (ELISA). The IMT was measured at the bifurcation of the external and internal carotid arteries. Asymptomatic vascular damage was identified as the IMT > 0.9 mm; an atherosclerotic plaque was verified when a focal structure encroached ≥ 0.5 mm or 50% of the adjacent IMT value into the carotid lumen or the IMT > 1.5 mm.
Results. Most RA patients (39/60; 65.0%) showed an increase in the IMT (> 0.9 mm); atherosclerotic plaques (IMT > 1.5 mm) were confirmed in 16 (26.7%) individuals, which was significantly more as compared to the control group. VWF was positively associated with the IMT [OR 1.1 (1.06-1.2), p < 0.001]. In addition, elevated levels of vWF were associated with disease activity. The highest values of vWF were found in patients with moderate RA activity (43.3 [21.2-56.9]). There was a positive correlation between vWF and ESR, CRP, DAS-28 (0.564, 0.455, and 0.573, respectively).
Conclusions. There was a positive correlation between vWF, inflammatory markers, and disease activity. VWF appeared to be a reliable predictor of the IMT score in RA patients.

Authors: Yalcin Tuba , Ozturk Elif Esra
Published: March 2023

Background. Chronotype is the attitude of a subject in determining the individual circadian preference in behavioral and biological rhythm associated with eating behaviors and health.

Objective. The aim of this study was to evaluate the associations between chronotype, adherence to the Mediterranean diet, and attitudes to healthy nutrition in Turkish adults.

Methods. A survey was conducted online using online platforms. A total of 1,197 volunteers between 18-65 years of age participated in our study. Participants’ adherence to the Mediterranean diet was assessed using the Mediterranean Diet Adherence Screener (MEDAS); their healthy eating attitude and chronotype were assessed using the Attitude Scale for Healthy Nutrition (ASHN) and the Morning-Evening Questionnaire (MEQ), respectively.

Results. Most of the participants were classified as those with an intermediate chronotype. More than half of evening-type participants and nearly half of intermediate-type participants had poor Mediterranean diet adherence. In addition, the percentages of individuals with morning and evening chronotypes in the very low and moderate classification ranges were similar and lower than the percentages of those with an intermediate chronotype. Linear regression analysis revealed that participants with higher MEQ values had higher ASHN and MEDAS scores and a lower body mass index as compared to those with lower MEQ values.

Conclusions. Chronotype was associated with Mediterranean diet adherence and healthy eating attitude. In particular, morning-type subjects showed higher adherence to the Mediterranean diet than intermediate- and evening-type subjects.

Published: March 2023

Background. After COVID-19 emergence, medical education witnessed a shift from face-to-face education to digital education, which inevitably affected medical students. Globally, due to the closure of schools and universities, medical education was shifted to electronic learning (E-learning).

This paper aimed to assess the effects of the COVID-19 pandemic on medical education and determine medical students’ knowledge, attitude, and practices towards E-learning in the Kurdistan Region of Iraq.

Materials and Methods. An online cross-sectional study was conducted among 500 undergraduate students of seven medical colleges in the Kurdistan Region, Iraq, in November 2021, to assess their state during the COVID-19 pandemic and how this affected their education.

Results. There were 50.6% of males and 49.4% of females. The mean age was 20.6 (± 1.5 SD) years. Approximately 17% of participants mentioned having financial issues, while 19.2% of students experienced health-related problems. As many as 67% of participants reported that the Internet quality was good or very good, whereas 46.8% of students disagreed that E-learning was a possible substitute for traditional learning. About two-thirds of participants agreed or were neutral that downloadable content was better than live content; however, only 19.2% of students agreed that E-learning could be used in the clinical aspect. A total of 52.2% of participants disagreed that E-testing could replace traditional learning methods. Surprisingly, 86.4% of students stated that they regularly used the Internet in their study.

Conclusions. E-learning was the main adjustment made in the educational system, including medical education. The study concluded with insights into how different circumstances could have different consequences on the efficacy of medical education. E-learning showed effective results in continuing learning until the educational system switched to a blended system. Training programs for medical education personnel are vital in effective E-learning opportunities.
Sagliker Syndrome – A Case Report
Authors: Smajić Matea , Smajić Petra , Zibar Lada
Published: March 2023

Aim: To present a case of Sagliker syndrome (SS), a rare syndrome caused by longterm heavy tertiary hyperparathyroidism (HPT) in end-stage renal disease (ESRD). Case report: In the year 2000, the 38-year-old man was diagnosed with ESRD. He is currently of low height, paraplegic, pigeon and barrel chested, with elongated upper extremities, deformed fingers, mandibular and maxillary asymmetric deformities with teeth malformations. Due to extremely high serum parathormone (PTH), resistant to pharmacological treatment, subtotal parathyroidectomy (PTx) was performed in 2007. However, he underwent parathyroid resurgery in 2010 for persistently high PTH of more than 2500 pg/mL (upper normal limit 69). In 2012, imaging found two suspected parathyroid glands and one of them was surgically removed. Postoperatively, the expected decrease in calcium and PTH serum concentrations did not occur. Ten years after the diagnosis of ESRD, the patient began to notice more pronounced skeletal deformities (upper, lower jaw, extremities, deformities of fingers, kyphoscoliosis) along with depressive disorder. Laboratory findings still show extremely high PTH (1994 pg/mL), low calcium, 1.89 mmol/L (normal range 2.14–2.53), and high alkaline phosphatase, 837 U/L (normal range 60–120), despite continuous pharmacological treatment. Conclusion: SS was firstly recognized by Yahya Sagliker in 2004 and it has not been described in Croatia to date. Pervasiveness and knowledge of the syndrome is still poor. The most efficient way of treating/preventing SS is early total PTx in severe secondary HPT related to ESRD. However, it can only stop progress of the disease, but cannot return skeletal deformities.
Determination of the relaxation characteristics for solvents from non-stationary spectra: the role of the gating pulse duration
Authors: Yermolenko I. P.  , Mikhailova V. A.  , Ivanov A. I.
Published: March 2023

The previously developed approach to the analysis of experimental spectra of non-stationary fluorescence has been improved by taking into account the effect of the duration of the gating pulse and a more accurate description of the initial stage of solvent relaxation. The exponential function used to describe the inertial component of relaxation has been replaced by the Gaussian function. This approach explicitly takes into account the reorganization and relaxation of the solvent and intramolecular vibrations. It includes an explicit description of the wave packet formation in the excited state of the fluorophore. The improvement of the approach made it possible to refine the relaxation characteristics of a number of solvents: ethylene glycol, dimethyl sulfoxide, butyronitrile, ethyl acetate, diethyl ether, dipropyl ether. Keywords: nonequilibrium of the nuclear subsystem, Stokes shift, relaxation of intramolecular vibrations, inertial component of solvent relaxation

Photoactive Cu-containing ZnO-ZnAl2O3 nanocomposites were synthesized by the polymer-salt method. To study the structure and properties of materials, the methods of luminescent spectroscopy and X-ray phase analysis were used. It has been shown that the resulting nanocomposites are capable of photogeneration of singlet oxygen under the action of UV and blue light. The synthesized materials consist of nanosized hexagonal ZnO crystals and cubic ZnAl2O4 crystals doped with Cu. The study of luminescent properties showed that nanocomposites can be used as down-converters of light that convert radiation from the UV-C range to UV-A and the visible spectral range. Keywords: singlet oxygen, nanoparticle, luminescence, ZnO, ZnAl2O4.

Published: March 2023

The method of selecting the most informative spectral channels when using an acousto-optic hyperspectrometer in the mode of selective spectral registration is presented. The developed technique makes it possible to select spectral channels in which the maximum contrast of objects is observed against a certain background, provided that their spectral properties are known. The results of experimental studies of the technique confirm an increase in contrast compared with panchromatic and hyperspectral shooting modes in the entire optical range. The choice of spectral channels according to the presented technique can also be used both for the formation of transmission functions in a multi-window acousto-optic hyperspectrometer, and for the rapid formation of their high-contrast color-synthesized images. Keywords: hyperspectral images, spectral contrast, visualization, acousto-optical filter, spectral density of energy brightness.

The results on measuring the impedance of a solid-state thin-film lithium-ion battery of the LiCoO2-LiPON-Si@O@Al electrochemical system in the temperature range from -20°С to 50°С are presented. A structural model is proposed and the parameters of its elements, providing the best fit for the experimental Nyquist diagrams, are calculated. It is shown that the main contribution to the internal resistance is made by the LiPON-LiCoO2 interface. Based on the temperature dependence of the LiPON solid electrolyte conductivity the activation energy of lithium is determined, which is in good agreement with the literature data.
Modeling Water Quality of AMD along the Flow Path
Authors: Schöpke Ralph
Published: March 2023

The water balance is severely disturbed in post-mining landscapes like Lusatia/Germany. Mine waters (amd) enter the environment and spread in groundwater and surface waters. Groundwater containing high amounts of pyrite weathering products flows into receiving waters due to lignite mining for several years. The Chair of Wassertechnik & Siedlungswasserbau at the Brandenburg University of Technology Cottbus-Senftenberg/Germany has developed a subsurface rehabilitation method using microbial sulfate reduction over the past 25 years. A continuation of the research is unlikely. This paper has presented some research results on the behavior of groundwater acidified by mining. The acidity in the surface and groundwater is specified via the negative neutralization potential. The dominant reactions in AMD genesis and migration through the aquifer are evaluated about their acidity formation or their buffering behavior. The behavior of AMD can be summarized in a simplified way in the acidity-sulfate diagram. A flow section model (PhreeqC2) was developed and parameterized based on this. This can describe the migration of quality changes in the groundwater/aquifer system. The aquifer passage is reduced to a filtration process, analogous to water treatment. The processes occurring at compartment transitions (dump-lake-aquifer-...) can be modeled from anoxic to oxic. A first case study produces the infiltration of neutralized opencast mining lake water into an aquifer influenced by mining. Measured absorption effects during a microbiological sulfate reduction are interpreted in the second case study with an extended flow path model. The results presented are recommended for use. A comprehensive summary of the results obtained over 25 years of research is being prepared.

Authors: Gioia Siena , Vlasac Irma M , Babazadeh Demsina , Fryou Noah L , Do Elizabeth , Love Jessica , Robbins Rebecca , Dashti Hassan S , Lane Jacqueline M
Published: March 2023

Background

Over the last decade, health mobile apps have become an increasingly popular tool used by clinicians and researchers to track food consumption and exercise. However, many consumer apps lack the technological features for facilitating the capture of critical food timing details.

Objective

This study aimed to introduce users to 11 apps from US app stores that recorded both dietary intake and food timing to establish which one would be the most appropriate for clinical research.

Methods

To determine a viable app that recorded both dietary intake and food timing for use in a food timing–related clinical study, we evaluated the time stamp data, usability, privacy policies, the accuracy of nutrient estimates, and general features of 11 mobile apps for dietary assessment that were available on US app stores. The following apps were selected using a keyword search of related terms and reviewed: text entry apps—Cronometer, DiaryNutrition, DietDiary, FoodDiary, Macros, and MyPlate; image entry apps—FoodView and MealLogger; and text plus image entry apps—Bitesnap, myCircadianClock, and MyFitnessPal.

Results

Our primary goal was to identify apps that recorded food time stamps, which 8 (73%) of the 11 reviewed apps did. Of the 11 apps, only 4 (36%) allowed users to edit the time stamps. Next, we sought to evaluate the usability of the apps using the System Usability Scale across 2 days, and 82% (9/11) of the apps received favorable scores for usability. To enable use in research and clinical settings, the privacy policies of each app were systematically reviewed using common criteria, with 1 (9%) Health Insurance Portability and Accountability Act–compliant app (Cronometer). Furthermore, protected health information was collected by 9 (82%) of the 11 apps. Finally, to assess the accuracy of the nutrient estimates generated by these apps, we selected 4 sample food items and a 3-day dietary record to input into each app. The caloric and macronutrient estimates of the apps were compared with the nutrient estimates provided by a registered dietitian using the Nutrition Data System for Research database. In terms of the 3-day food record, the apps were found to consistently underestimate daily calories and macronutrients compared with the Nutrition Data System for Research output.

Conclusions

Overall, we found that the Bitesnap app provided flexible dietary and food timing functionality capable of being used in research and clinical settings, whereas most other apps lacked in the necessary food timing functionality or user privacy.
Yearly Energy, Exergy, and Environmental (3E) Analyses of A Photovoltaic Thermal Module and Solar Thermal Collector in Series
Authors: AL-aridhee Sameer Teref Azeez , Moghiman Mohammad
Published: March 2023

The annual performance of a hybrid system of a flat plate photovoltaic thermal system and a solar thermal collector (PVT/ST) is numerically analyzed from the energy, exergy, and environmental (CO2 reduction) viewpoints. This system can produce electricity and thermal power simultaneously, with higher thermal power and exergy compared to conventional photovoltaic thermal systems. For this purpose, a 3D transient numerical model is developed for investigating the system's performance in four main steps: (1) investigating the effects of the mass flow rate of the working fluid (20 to 50 kg/h) on the temperature behavior and thermodynamic performance of the system, (2) studying the impacts of using glass covers on the different parts of the system, (3) evaluating the annual energy and exergy analyses of the system under Mashhad weather conditions, and (4) examining the CO2 reduction by using the proposed system. The results show that for the (glazed) PVT and (glazed) ST systems, increasing the mass flow rate of the working fluid from 20 to 50 kg/h results in 22% and 1.5% improvements in both thermal and electrical power, respectively. However, the thermal exergy of the system decreases by 40.1%. Furthermore, the (glazed) PVT/(glazed) ST systems generate approximately 86% and 264% more thermal power and energy than the PVT/ST systems, respectively. Using a (glazed) PVT/(glazed) ST system with a working fluid’s mass flow rate of 50 kg/h results in maximum thermal and electrical efficiencies of 40.7% and 16.22%, respectively. According to the annual analysis, the highest average thermal and electrical power, equal to approximately 338.3 and 24 W, respectively, is produced in August. The amount of CO2 reduction increases by increasing the mass flow rate and using a glass cover. The PVT/(glazed)ST system has the potential to reduce CO2 emissions by 426.3 kg per year.
Design a radio receiver for solar activity observation in VLF band
Authors: Al Banna Ahmed
Published: March 2023

Solar activity monitoring is important in our life because of its direct or indirect influence on our life, not only on ionospheric communications. To study solar activity, researchers need measuring and monitoring instruments, these instruments are mostly expensive and are not available in all universities. In this paper, a very low frequency radio receiver had been designed and implemented with components available in most markets to support the researchers, college students, and radio astronomy amateurs with a minimum input voltage less than 100µV, an output voltage less than 135 m V with no distortion and an overall gain of 34dB. A comparison had been done between two circuit structures using a workbench software program and experimentally done in the lab. Two antennas were experimentally tested and a loop antenna was chosen. The whole system was connected and tested to receive signals in the Lab and monitored on computer using HDSDR software program. Another experiment done outside the lab (at home), and the result was not good because of many high level interference noises.

Mycoplasma pneumoniae is recognized as the leading cause of community-acquired lower respiratory tract infection in children, accounting for a significant proportion of pediatric mortality. Macrolides are the first-line treatment for M. pneumoniae infections. However, the extensive use of macrolides in clinical practice resulted in the emergence of macrolide-resistant M. pneumoniae (MRMP), which has a negative impact on treatment outcomes. Hence, in the present study, MRMP was determined in hospitalized children with community-acquired pneumonia (CAP). Real-time PCR detected M. pneumoniae in 41 of 348 clinical samples. Sanger sequencing revealed that none of the isolates were associated with the A2063G or A2064G base mutation, which confers macrolide resistance, in domain V of the 23S rRNA gene. Although MRMP was not observed in children with CAP in our study, healthcare practitioners should be vigilant about the potential risk of MRMP infections.

Abstract: This study proposes a method for recognising motions through image processing. In this project, we create a sign detector that can be readily enhanced to recognise a wide range of various signs and hand gestures, such as the alphabets, and that can recognise numbers from 1 to 10.. We used the Python Keras and OpenCV libraries to create this project. Applications for this project are incredibly diverse. Machine learning is usedto build models, extract key features, and construct applications since it has access to enormous databases. Machine learning can be used in our daily lives to make living easier. Deep learningis used to detect signs in sign language, which is a complicated process.

Published: March 2023

Eating patterns that emphasize healthy, plant-predominant foods, as opposed to animal-derived products, are associated with reductions in cardiovascular (CV) risk and should be promoted to patients. We created a hospital initiative to educate the multidisciplinary staff to serve as advocates for healthy eating to our patients. Housestaff engagement may be a promising mechanism to educate patients and encourage food and nutrition changes across a health system.
Dairy Intake and Incidence of Common Cancers in Prospective Studies: A Narrative Review
Authors: Herby Anna , Josh Cullimore  , Jennifer Paul-Quinn  , Lee Crosby
Published: March 2023

Dairy products are commonly consumed and sometimes recommended by governmental authorities; however, significant evidence indicates that dairy consumption modifies cancer risk. Prospective studies examining the relationship between dairy intake and cancer of the prostate, breast, ovary, and colorectum were reviewed. These studies indicate that dairy consumption is associated with prostate cancer risk, possibly as a consequence of dairy-induced increases in circulating IGF-1 concentrations and the calcium and estrogen content of dairy products. Evidence also suggests a positive association between dairy intake and ovarian cancer. Findings on breast cancer have been mixed; however, recent studies of populations with a wide range of dairy intakes have shown clear associations between dairy intake and breast cancer risk. In contrast, there is a negative association between dairy products and colorectal cancer, which is likely driven by the protective effect of calcium. Current evidence suggests that dairy intake is associated with increased risk of prostate, ovarian, and possibly breast cancer, and reduced risk of colorectal cancer.

Representações da violência contra mulheres na narrativa seriada Coisa mais linda (2019)
Authors: Scher Crislaine Alessandra de Lima , Santos Paula Maria Lucietto Dylbas dos , Fiuza Adriana Aparecida de Figueiredo
Published: March 2023

O presente artigo tem por objetivo a análise da representação da violência contra as mulheres e o feminicídio na primeira temporada da série brasileira da Netflix – Coisa Mais Linda, lançada em 2019. O título da produção audiovisual é uma homenagem à canção “Garota de Ipanema'', de Tom Jobim e Vinicius de Moraes, de 1962, que tem, no primeiro verso da letra, a expressão “coisa mais linda”. A narrativa seriada, ambientada no fim da década de 1950, retrata a história de Maria Luiza Carone – Malu, Lígia Soares, Adélia Araújo e Theresa Soares, que vivem na ficção uma sequência de situações que evidenciam a condição da mulher em uma sociedade regida pelo sistema patriarcal. As análises foram elaboradas a partir de estudos bibliográficos, considerando o contexto histórico, as relações entre cinema, crítica feminista, os estudos de gênero e das múltiplas formas das violências a partir de autores e autoras como Eco (1989), Buonnano (2019), Curi (2021), Lerner (2019), Butler (2003), Bourdieu (2002), Saffioti (1987). Constatamos que as violências sofridas pelas personagens femininas da ficção podem ser encontradas nos diversos casos de violência de gênero na sociedade contemporânea, representando discursos racistas, sexistas e misóginos contra as mulheres.
Violência contra as mulheres negras em A vida depois do tombo (2021)
Authors: Paiva Carla Conceição da Silva , Santos Mariane Ribeiro dos
Published: March 2023

Este artigo analisa a representação das mulheres negras no documentário A vida depois do tombo (2021). Por meio do feminismo negro e da análise de conteúdo, foi possível constatar que, há uma dubiedade de narrativas, que ora humaniza, ora demoniza a figura de Karol Conká, reforçando mais a imagem negativa construída no mundo das telas pelo BBB2. O principal equívoco na construção da narrativa foi a tentativa em emular um cenário virtual, em que a personagem se vê enclausurada no erro, na culpa e na solidão.
