Published: July 2023

Abstract
Coronary ostial atresia is a developmental abnormality that typically causes asymptomatic anomalies in the coronary blood supply. This case report, which presents 2 symptomatic patients with right coronary artery abnormalities, explores difficulties in diagnosing coronary ostial atresia and distinguishing it from single coronary artery and coronary artery disease–related acquired occlusion. Factors underlying management decisions are also discussed.

Authors: Rayhan Amar 
Published: July 2023

Background : Anyone has the potential to get injured, especially burns. Hydrogel membrane and liquid smoke are a combination of antibacterial, anti-inflammatory and antioxidant properties. These properties play an important role in wound healing. In wound healing, the re-epithelialization process is a critical parameter for the success of wound closure.Aim : Analyzed the effect of re-epithelialization length on burns of rats given a liquid smoke combination hydrogel membrane.Methods : Experimental research used post test only with control group design. The number of samples was 15 white wistar rats with burns which were divided into two treatment groups, namely P1 (liquid smoke combination hydrogel membrane), P2 (liquid smoke) and one control group K (hydrogel membrane). Assessment of reepithelialization length has been calculated using a microscope. Statistical test using One Way ANOVA – Post Hoc Bonferroni test.Results : The average length of re-epithelialization (µm) for each group was (P1) 2004.91, (P2) 1534.15 and (K) 1248.16. Based on the results of the One Way ANOVA analysis, we found p value = 0.028 (p <0.05). This shows that there were significant differences in the data between groups.Conclusions : There was a significant difference on the length of re-epithelialization in rats burn wound between hydrogel membrane group with liquid smoke, liquid smoke group and control group.

Peningkatan kasus TBC saat pandemi COVID-19 karena isolasi sosial memicu penularan TBC di rumah akibat kontak erat selama isolasi. Hal ini menyebabkan keterlambatan diagnosis sehingga meningkatkan kejadian tuberkulosis. Sikap memiliki pengaruh besar terhadap terbentuknya perilaku pencarian pelayanan kesehatan orangtua dengan anak TBC. Penelitian ini bertujuan untuk mengetahui gambaran sikap dan perilaku pencarian pelayanan kesehatan orang tua dengan anak TBC di RSUD Al-Ihsan. Penelitian ini merupakan penelitian deskriptif kuantitatif dengan pendekatan retrospektif dan teknik purposive sampling. Kriteria sampel adalah orang tua yang memiliki anak dengan TBC sebanyak 67 sampel. Untuk mengukur sikap dan perilaku menggunakan kuesioner KAP Surveys yang dikembangkan oleh WHO. Analisis data pada penelitian ini menggunakan distribusi deskriptif kuantitatif. Hasil penelitian sikap dengan reaksi orang tua ketika anaknya tertular TBC sebagian responden (50,7%) takut tertular TBC dan seluruh responden (95,5%) ketika anaknya tertular penyakit TB mengajak bicara dokter dan tenaga kesehatan. Adapun perilaku pencarian pelayanan kesehatan orangtua dengan anak tuberkulosis sangat bervariasi, lebih banyak responden yang memilih pusat kesehatan, segera ke pelayanan kesehatan setelah gejala TBC muncul dan faktor penghambat pergi ke layanan kesehatan adalah biaya, jarak, dan ketidaktahuan. Sikap orang tua terhadap TBC sangat serius dan menganggap anaknya berpotensi dapat tertular penyakit TBC. Sikap ini sesuai dengan perilaku pencarian tempat pelayanan kesehatan. Penelitian selanjutnya diharapkan menganalisis determinan sikap dan perilaku orangtua anak dengan TB dalam mengakses pelayanan kesehatan.

Penelitian selanjutnya diperlukan untuk menguji jumlah makanan tinggi kalium yang harus dikonsumsi secara tepat.
The impact of test positivity on surveillance with asymptomatic carriers
Authors: Gaspari Mauro 
Published: July 2023

Abstract

Objectives
Recent studies show that Test Positivity Rate (TPR) gains a better correlation than incidence with the number of hospitalized patients in COVID-19 pandemic. Nevertheless, epidemiologists remain sceptical concerning the widespread use of this metric for surveillance, and indicators based on known cases like incidence rate are still preferred despite the large number of asymptomatic carriers, which remain unknown. Our aim is to compare TPR and incidence rate, to determine which of the two has the best characteristics to predict the trend of hospitalized patients in the COVID-19 pandemic.

Methods
We perform a retrospective study considering 60 outbreak cases, using global and local data from Italy in different waves of the pandemic, in order to detect peaks in TPR time series, and peaks in incidence rate, finding which of the two indicators has the best ability to anticipate peaks in patients admitted in hospitals.

Results
On average, the best TPR-based approach anticipates the incidence rate of about 4.6 days (95 % CI 2.8, 6.4), more precisely the average distance between TPR peaks and hospitalized peaks is 17.6 days (95 % CI 15.0, 20.4) with respect to 13.0 days (95 % CI 10.4, 15.8) obtained for incidence. Moreover, the average difference between TPR and incidence rate increased to more than 6 days in the Delta outbreak during summer 2021, where presumably the percentage of asymptomatic carriers was larger.

Conclusions
We conclude that TPR should be used as the primary indicator to enable early intervention, and for predicting hospital admissions in infectious diseases with asymptomatic carriers.

Abstract
Multimedia and mobile learning are effective teaching tools because of their many useful characteristics. Transmission of educational material to students is facilitated by technology in both multimedia and mobile learning environments. A more interesting and engaging learning experience may be achieved by combining text, graphics, music, video, and animation. Media-rich classrooms are often referred to as “multimedia learning.” In contrast, students who use mobile learning may access their courses from any place with an internet connection and a mobile device such as a smartphone or a tablet. Whenever this involves commonplace technological needs, its cellular gadget and notably its clever telephone take the cake. Smartphone gadgets have a very wide range of potential applications and uses. Some ethical considerations are preventing media from reinforcing stereotypes or prejudice in the communities where they are utilized. Student information are gathered and used in a way that protects their privacy, with materials required for students to engage in mobile learning, and respecting intellectual property and copyright regulations while using multimedia language-learning tools. This importance of learning cannot be overstated but when such results come, mobile devices have increasingly been used in schools. This question of whether mobile devices have an impact on education remains open. Because of such “mobile gaining knowledge,” along with an overall phrase describing researching where different devices could be utilized in combination to enhance schooling, mobile devices had become more popular. Because today’s kids utilize their mobile devices frequently, studies on their effect on word learning are immediately required. This pilot research seeks to understand why school learners think via smartphone-based L2 exercises. In particular, this study collects data about several plenty applications using cell phones in linguistic research. Two hundred and ninety-four college children from one top Turkish institution participated in this research. This project uses some hybrid reporting models and relies on description analysis over its methodology. Their results show that users place one high value on obtaining ready accessibility to materials while studying some foreign language. Respondents not only remarked about their cellphone’s portability but also proposed new applications for enhancing their learning in other countries.

Published: July 2023

Abstract
Biosurfactants are amphiphilic compounds synthesized from plants and microorganisms and are known for their high biodegradability, low toxicity, and eco-friendliness. They have diverse applications in industrial and environmental fields, including oil recovery, bioremediation, and cleaning up hydrocarbons from polluted areas. Surfactin is a potent lipopeptide biosurfactant produced by Bacillus subtilis bacteria. In this study, we produced surfactin by B. subtilis using cassava wastewater as the fermentation medium. This production was monitored by high performance liquid chromatography (HPLC). Approximately 600 mg L−1 of surfactant was produced. The oil displacement test was then performed to evaluate the effectiveness of crude and purified surfactin compared to a synthetic surfactant and a biosurfactant. Three types of surfactants were tested: the synthetic surfactant sodium lauryl sulfate (SDS), the commercial biosurfactant rhamnolipid (Rh), and surfactin in its crude form and purified one – after acid precipitation. The analysis results indicated that surfactin, in both its crude and purified forms, was more effective at dispersing oil than the other surfactants tested, even at lower concentrations. This suggests that biosurfactants have great potential as a more sustainable and effective alternative to petroleum-derived synthetic surfactants. Surfactin can be applied without the need for downstream processes.

Abstract
Loewen, B, Melton, B, Maupin, D, and Ryan, G. Comparing acute responses between single session circuit training and fireground suppression tasks. J Strength Cond Res 37(8): 1667–1678, 2023—The purpose of this study was to compare the cardio-metabolic and perceived demands of task-specific circuit training to fireground suppression tasks (FST). Twenty-three career, structural firefighters performed three separate testing days (i.e., FST, CT, and CTW). FST consisted of performing seven common occupational tasks in full gear (∼22.5kg). The weighted (CTW: 18.9kg vest) and unweighted (CT) circuit utilized seven exercises designed to mimic the FST's. Measurements included relative heart rate (%HRmax), post-training blood lactate (Lapost), change in countermovement jump height (▵CMJ), change in dominant and non-dominant handgrip strength (▵DHG and ▵NDHG), total training time, rating of perceived exertion (RPE), and job-specific rating of relevance. A repeated measure analysis of variance (ANOVA), with Bonferroni post-hoc, was performed for each variable, excluding RPE and rating of relevance. Friedman's ANOVA was used to assess differences in RPE and rating of relevance, with Wilcoxen Signed Rank tests follow-up. Significant mean differences were found in %HRmax between CT and FST (∼8.6%, p < 0.01, d = 1.12) and CTW and FST (∼5.3%, p < 0.01, d = 0.75), ▵CMJ between CT and FST (p < 0.01, d = 1.35) and CTW and FST (p < 0.01, d = 1.09), ▵NDHG between CTW and FST (p = 0.01, d = 0.79), training time between CT and FST (p < 0.01, d = 1.00) and CTW and FST (p < 0.01, d = 1.81), and rating of relevance between CT and FST (PS
dep = 0.67). In conclusion, CT and CTW were able to elicit similar metabolic and perceived demands as FST, while producing a lower cardiovascular response. Therefore, while circuit training may be a beneficial training tool for firefighters, it cannot replicate FST.

Abstract
Hermes, MJ and Fry, AC. Intentionally slow concentric velocity resistance exercise and strength adaptations: a meta-analysis. J Strength Cond Res 37(8): e470–e484, 2023—Intentionally slow-velocity resistance exercise (ISVRE) is suggested by some to be equally or more effective than fast or traditional velocities for increasing muscular strength. The purpose of this meta-analysis was to assess the effect ISVRE has on strength adaptations compared with faster or traditional velocities, with subgroup analyses exploring age, sex, and training status as confounding factors on the influence of velocity on strength adaptation. Eligible studies (n = 24) were required to be chronic (multiple weeks) randomized or nonrandomized comparative studies using dynamic constant external resistance for training and testing, and pre-post strength assessments. All studies examined healthy individuals (n = 625; fast or traditional n = 306, intentionally slow n = 319). A random-effects meta-analysis indicated a significant (p ≤ 0.05) effect in favor of fast training (effect size [ES] = 0.21, 95% confidence interval [CI] = 0.02–0.41, p = 0.03). Publication bias was noted through trim and fill analysis, with an adjusted effect size estimate of 0.32 (p < 0.001). Subgroup analyses indicated no difference between trained and untrained subjects (QM = 0.01, p = 0.93), and no difference between older and younger subgroups (QM = 0.09, p = 0.77), despite younger favoring faster (ES = 0.23, p = 0.049) and older not favoring either velocity (ES = 0.16, p = 0.46). Subgroup analysis also indicated women favored faster training (ES = 0.95, p < 0.001) in comparison to men (ES = 0.08, p = 0.58). Contrary to some previous reviews, these results indicate that chronic fast or traditional velocity resistance exercise increases muscular strength to a greater degree than ISVRE training. Resistance training velocity must be considered if strength is a desired outcome.

Abstract
Lockie, RG, Wakely, AM, Viramontes, E, and Dawes, JJ. A research note on relationships between age, body size, strength, and power with throwing velocity in high school water polo players. J Strength Cond Res 37(8): e466–e469, 2023—A successful high school strength and conditioning program should aim to improve fitness and develop motor skills in athletes. This research note investigated the relationships between throwing velocity with age, height, body mass, strength, and power in male high school water polo athletes. Fifteen (n = 15) water polo athletes (age: 15.67 ± 0.98; height: 177.63 ± 6.53 cm; body mass: 78.07 ± 16.08 kg) from one high school program were recruited. Strength was measured using combined grip strength from both hands and a leg/back dynamometer. Power was measured by a vertical jump and 2-kg seated medicine ball throw (MBT). Subjects also threw a water polo ball with maximum effort to measure throwing velocity. Pearson's correlation and stepwise regression were used to calculate relationships between throwing velocity with age, body size, strength, and power (p < 0.05). Age (r = 0.530), grip strength (r = 0.674), leg/back strength (r = 0.699), and the MBT (r = 0.670) all showed significant positive relationships with throwing velocity. Leg/back strength predicted throwing velocity with 49% explained variance (r

2
= 0.490, p < 0.004). With age, explained variance increased to 66% (r

2
= 0.664, p < 0.001). Throwing velocity related to age, which could be expected with maturation. However, stronger relationships were seen for upper-body (grip) and lower-body (leg/back) strength, and upper-body power (MBT). Strength and conditioning programs for high school athletes who develop upper- and lower-body strength and upper-body power could enhance throwing velocity among water polo (and potentially other overhead throwing) athletes.

Abstract
Cabarkapa, D, Eserhaut, DA, Cabarkapa, DV, Philipp, NM, and Fry, AC. Salivary testosterone and cortisol changes during a game in professional male basketball players. J Strength Cond Res 37(8): 1687–1691, 2023—The purpose of this study was to examine acute changes in salivary testosterone (T), cortisol (C), and testosterone-to-cortisol ratio (T/C) during a simulated 5-on-5 basketball game. Seven professional male basketball players volunteered to participate in this study. Repeated-measures analysis design was used to examine changes in hormonal concentrations across 8 testing time points: immediately upon arrival to the gymnasium-baseline (BS); post–warm-up (PW); post-first (P1Q), second (P2Q), third (P3Q), and fourth quarter (P4Q); and 30 (P30) and 60 minutes (P60) postgame. The findings of this study indicate that a simulated 5-on-5 basketball game provoked significant changes in salivary T, C, and T/C. When compared to the BS levels (x̄ ± SD [nmol·L−1]; 6.72 ± 2.53), salivary C concentration experienced a notable increase P3Q (16.20 ± 7.70) and remained elevated throughout the rest of the sampling periods, with values failing to return to BS levels P60 (11.88 ± 5.58). Conversely, a significant increase in salivary T occurred P1Q (0.76 ± 0.21) when compared to the BS levels (0.58 ± 0.12) and remained elevated up to P30 (0.75 ± 0.20), with values returning to BS levels P60 (0.63 ± 0.14). In addition, despite no significant intragame alterations, T/C exhibited a notable decrease P30 (0.06 ± 0.02) and P60 (0.07 ± 0.04), when compared to BS values (0.10 ± 0.04). Overall, these findings provide additional insight into the physiological stress that basketball players are exposed to during 5-on-5 competitive play and can be used to appropriately adjust and monitor training loads to optimize recovery and on-court basketball performance.
Representation of Motion Direction in Visual Area MT Accounts for High Sensitivity to Centripetal Motion, Aligning with Efficient Coding of Retinal Motion Statistics
Authors: Kumano Hironori , Uka Takanori 
Published: July 2023

The overrepresentation of centrifugal motion in the middle temporal visual area (area MT) has long been thought to provide an efficient coding strategy for optic flow processing. However, this overrepresentation compromises the detection of approaching objects, which is essential for survival. In the present study, we revisited this long-held notion by reanalyzing motion selectivity in area MT of three macaque monkeys (two males, one female) using random-dot stimuli instead of spot stimuli. We found no differences in the number of neurons tuned to centrifugal versus centripetal motion; however, centrifugally tuned neurons showed stronger tuning than centripetally tuned neurons. This was attributed to the heightened suppression of responses in centrifugal neurons to centripetal motion compared with that of centripetal neurons to centrifugal motion. Our modeling implies that this intensified suppression accounts for superior detection performance for weak centripetal motion stimuli. Moreover, through Fisher information analysis, we establish that the population sensitivity to motion direction in peripheral vision corresponds well with retinal motion statistics during forward locomotion. While these results challenge established concepts, considering the interplay of logarithmic Gaussian receptive fields and spot stimuli can shed light on the previously documented overrepresentation of centrifugal motion. Significantly, our findings reconcile a previously found discrepancy between MT activity and human behavior, highlighting the proficiency of peripheral MT neurons in encoding motion direction efficiently.SIGNIFICANCE STATEMENTThe efficient coding hypothesis states that sensory neurons are tuned to specific, frequently experienced stimuli. Whereas previous work has found that neurons in the middle temporal (MT) area favor centrifugal motion, which results from forward locomotion, we show here that there is no such bias. Moreover, we found that the response of centrifugal neurons for centripetal motion was more suppressed than that of centripetal neurons for centrifugal motion. Combined with modeling, this provides a solution to a previously known discrepancy between reported centrifugal bias in MT and better detection of centripetal motion by human observers. Additionally, we show that population sensitivity in peripheral MT neurons conforms to an efficient code of retinal motion statistics during forward locomotion.
