A Molecular Study of Toxic Shock Syndrome Toxin gene (tsst-1) in β-lactam Resistant Staphylococcus aureus Clinical Isolates
Authors: Nariman Nidhal Omar  , Rana Kadhim Mohammed  
Published: April 2021

Three hundred and sixty different samples were collected from different sources, including wound, burn, nasal, and oral swabs from several hospitals in Baghdad. A number of 150 (53%) Staphylococcus aureus samples were isolated and identified among a total of 283 samples. Then, the spread of the Toxic Shock Syndrome Toxin-1 gene (tsst-1) was investigated in β-lactamase resistant S. aureus. According to the source of samples, the distribution of S. aureus isolates was found to be significantly higher (p < 0.01) in wound samples as compared to other sources. According to the age, a highly significant distribution (p < 0.01) was recorded in the age group of 15-30 years, whereas gender comparison showed no statistically significant differences. All the isolates were subjected to susceptibility test against eight β-Lactam antibiotics by using the disc diffusion method. The antimicrobial susceptibility test showed that S. aureus had maximum resistance percentage to Carbenicillin (97.3%), while the lowest resistance rate was against Meropenem, with a sensitivity rate of up to 82%. In addition, 144 (96%) out of the 150 S. aureus isolates have multiple drug resistance (MDR). All the isolates were subjected to polymerase chain reaction to amplify tsst-1 toxin gene. A number of 70 isolates (46.7%) were found to be positive for tsst-1 gene. The results showed no significant correlation between tsst-1 gene with the individual antibiotic resistance and the multi-drug resistance patterns of the isolates (p = 0.226).
Performance Analysis of a SWIPT Enabled UAV-Assisted Relaying
Authors: Chowdhury Imtiaz Akber 
Published: April 2021

In the recent era, unmanned aerial vehicle (UAV) plays an important role in numerous application fields related to the wireless communication system. Due to its precise control, efficient deployment, and affordable cost, UAV-assisted communication attracts significant attention to all the sectors including the defense sector, agriculture sector, and security purpose, and so on. Though UAVassisted relaying has enormous advantages but there are potential challenges while UAV deploys as a relay. For example, deploying UAV in the wireless communication field, its battery life is the main concern due to its limited battery size and storage capacity. To get significant benefits from UAV while deployed in the cooperative communication network, the battery status of the UAV is an unavoidable issue. To minimize the aforementioned problem, energy harvesting (EH) techniques can be an efficient solution. The UAV can harvest energy from the transmitted power by the source and with the help of this harvested energy UAV can retransmit the signal to the destination. However, there are several parameters that also significantly influence the UAV-based cooperative system performance such as UAV’s position, time allocation factor and power allocation factor, and UAV’s height. Considering the importance of the aforementioned parameters, in this paper, we have considered simultaneous wireless information and power transfer (SWIPT) enabled UAV-assisted relaying network and evaluate the system outage performance with different parameters aspects. We have provided some insight about the parameters such as the UAV’s position, the power allocation factor and the time allocation factor and the UAV’s height by providing simulation results such as the outage probability versus transmit power in the different urban scenario, the outage probability versus time allocation factor and power allocation factor and the outage probability versus UAV’s height. These simulation results clearly show the significance of the abovementioned parameters in wireless-powered UAVassisted cooperative communication.

Hydrocarbon Prospectivity in the undrilled area of AIMA Field in the Niger Delta Basin, Nigeria.
Authors: Ogbamikhumi Alexander , Ighodalo John Elvis 
Published: April 2021

Field development is a very costly endeavor that requires drilling several wells in an attempt to understanding potential prospects. To help reduce the associated cost, this study integrates well and seismic based rock physics analysis with artificial neural network to evaluation identified prospects in the field.
Results of structural and amplitude maps of three major reservoir levels revealed structural highs typical of roll over anticlines with amplitude expression that conforms to structure at the exploited zone where production is currently ongoing. Across the bounding fault to the prospective zones, only the D_2 reservoir possessed the desired amplitude expression, typical of hydrocarbon presence. To validate the observed amplitude expression at the prospective zone, well and seismic based rock physics analyses were performed. Results from the analysis presented Poisson ratio, Lambda-Rho and Lambda/Mu-Rho ratio as good fluid indicator while Mu-Rho was the preferred lithology indicator.
These rock physics attributes were employed to validate the observed prospective direct hydrocarbon indicator expressions on seismic. Reservoir properties maps generated for porosity and water saturation prediction using Probability Neural Network gave values of 20-30% and 25-35% for water saturation and porosity respectively, indicating the presence of good quality hydrocarbon bearing reservoir at the prospective zone.

Authors: Suresh Megha , Jain Swati , Kaul Neena Bhatia 
Published: April 2021

The present study was conducted to assess the usefulness of MUAC as a screening tool to assess nutritional status during pregnancy (>20 weeks). Pregnant women (>20 weeks of gestation, n=100) were enrolled from tertiary care ANC clinics in urban areas of Delhi. Data on socio-demographic profile was collected using pre-tested questionnaires. The blood pressure and anthropometric parameters (weight, height and MUAC) were recorded. The mean height, weight and MUAC of pregnant women were 152.15 ± 4.93cm, 56.7 ± 6.7Kgs and 25.5 ± 2.60cm respectively. Weight gain between trimesters and overall weight gain showed no correlation with blood pressure. Maternal weight was positively correlated with MUAC (p=0.00), SBP (p=0.006) and DBP (p=0.02). Maternal height was negatively correlated with MUAC (p=0.012). BMI and MUAC showed a significantly positive correlation (p=0.00), which indicates the versatility of this tool. However, no association was observed between MUAC and blood pressure during pregnancy in the present study.

Published: April 2021

Beyond having a good degree, graduates are expected to have relevant skills and attributes required to compete and collaborate in a rapidly changing work environment. In recent times, the employability of Nutrition and Dietetics graduates in Nigeria has been of considerable concern. This study was designed to assess the readiness of trainees in the field of Nutrition and Dietetics from Nigerian Universities for career and work engagements.
This descriptive cross-sectional study was carried out among 109 final-year undergraduate and postgraduate students from twelve universities offering Nutrition and Dietetics programme across Nigeria. Data was collected using a semi-structured online questionnaire. Data obtained were background information on the students, their experiences and challenges in their academic pursuits, willingness and readiness to pursue and engage in Nutrition and Dietetics related jobs, as well as their perception of skills and competences for future career and work engagements. The data were analysed using the IBM SPSS version 20.0.
About 73% of the respondents were females, mainly between ages 21 and 25 years (62.4%) and undergraduates (70%). Among the undergraduate students, 83.4% had chosen to study Nutrition and Dietetics as a result of personal interest and choice while the postgraduate trainees indicated acquisition of in-depth knowledge of nutrition (60.6%) and quest to enhance career profile for competitive advantage in job pursuits (39.4%) as the core reasons for their choice for the programme. Nearly all the respondents (96.3%) reported having enjoyed their training programs. Only half (50.5%) perceived themselves to be “very ready” and well-prepared for work and career engagement. The top three areas of interest by trainees in Nutrition and Dietetics were Clinical Nutrition and Diet Therapy (60.6%), Community and Public Health Nutrition (43.1%), and Sports Nutrition (11.0%). Three out of every ten trainees had no specific desired skills and competences. While less than half declared that they had no knowledge of the skills and competences desired by employers of nutrition graduates, two-thirds of the trainees perceived themselves as eligible for their choice of work and career.
This study shows that most Nutrition and Dietetics trainees in Nigerian universities are ready and willing to start a career in the field. However, many lack the knowledge of expected skills and competences needed for career engagement.

Authors: Triplett Craig R , Dorrel Bryan S , Symonds Matthew L , Selland Corey A , Jensen Daniel D , Poole Christopher N 
Published: April 2021

Background The Functional Movement Screen (FMS™) is a popular test used by sports medicine professionals to identify dysfunctional movement patterns by analyzing mobility and stability during prescribed movements. Although the FMS™ has been a popular topic of research in recent years, normative data and asymmetries in college-aged students have not been established through research. Purpose The objective was to determine normative FMS™ scores, report frequency counts for FMS™ asymmetries, and determine if the number of sports seasons and number of different sports an individual participated in during high school varied between university students that showed FMS™ identified asymmetries. Study Design Cross-sectional Study Methods One hundred university students completed the FMS™ and an associated survey to determine which sport(s) and for how many seasons they participated in each sport(s) during high school. Total FMS™ scores were assessed as well as identifying the presence of an asymmetry during a FMS™ screen. An asymmetry within the FMS™ was defined as achieving an unequal score on any of the screens that assessed right versus left movements of the body. Data Analysis Data analysis included descriptive statistics, Pearson correlation was utilized to investigate the relationship between number of sports played and number of sport seasons. Shapiro Wilk test for normality, and Mann Whitney U test was employed to investigate group differences in number of sports played. All analyses were conducted using SPSS software. Results Statistically significant correlations (r = .286, r2 = .08, p < 0.01) were found for both number of sport seasons and number of sports with FMS™ total score. In addition, participants without FMS™-detected asymmetries played significantly more seasons and more sports than their peers that presented asymmetries (U = 946.5, z = -1.98, p = 0.047). Finish with the actual p-value in parenthesis. Conclusion Participating in multiple sports and multiple sport seasons during high school was associated with higher FMS™ total scores. Results suggest that participating in multiple sports and multiple sport seasons was associated with fewer asymmetries, which may decrease subsequent injury risk. Level of Evidence 3b

Published: April 2021

Background Training programs that include the Nordic hamstring exercise (NHE) have been shown to increase eccentric knee flexor strength and biceps femoris fascicle length in male athletes. However, the effect of NHE on female athletes remains unknown. Purpose To investigate the collective and individual responses of professional female soccer players engaged in a preseason training program with the NHE regarding eccentric knee flexor strength and biceps femoris long head fascicle length. Study Design Quasi-experimental study. Methods Sixteen amateur female soccer players (without a NHE training routine) were evaluated 8-weeks apart to: (1) assess reliability of eccentric knee flexor strength and biceps femoris fascicle length measures; and (2) determine the typical error of measures that would be used to discriminate training responders and non-responders. The NHE training group had 17 professional female soccer players who performed an 8-week training program with the NHE during preseason. Within-group analysis was performed with paired sample t-tests (pre- vs. post-training), and individual responses were determined using the typical error criteria. Results The non-trained group’s data demonstrated that measures of strength (ICC=0.82-0.87, typical error = 12-13 N) and fascicle length (ICC=0.92-0.97; typical error = 0.19-0.38 cm) were reliable. In the NHE training group, both limbs increased the eccentric knee flexor strength (~13%; ES=0.74-0.82) and the biceps femoris fascicle length (~6%; ES=0.44-0.65). Twelve players (~71%) were considered responders to the NHE training program for the eccentric knee flexor strength, while eight athletes (~47%) were responders for the biceps femoris fascicle length. Conclusion The 8-week preseason training program with the NHE increased both eccentric knee flexor strength and biceps femoris fascicle length in professional female soccer players. More than two-thirds of players demonstrated a meaningful increase in eccentric strength, while nearly half achieved consistent fascicle length increases with the NHE training.

Authors: Long Katherine L , Milidonis Mary K , Wildermuth Veronica L , Kruse Adam N , Parham Uniqua T 
Published: April 2021

Background Professional ballet dancers suffer high injury rates and are less likely than other athletes to specifically train to improve muscular strength, coordination, agility, speed and motor control because of heavy training demands, aesthetic appearances and financial barriers. Hypothesis/Purpose The purpose of this study was to examine the effects of a supplemental conditioning program on professional and pre-professional contemporary ballet dancers. The authors hypothesized that those participating in a training program would reduce injury rate by improving their motor control, stability, balance and physical function. The authors aimed to observe the feasibility and qualitative phenomena related to a conditioning program from the dancer’s perspective. Study Design A mixed-methods study; within subject quasi-experimental design and qualitative interviews. Methods Six professional classical and contemporary ballet dancers completed the five-week conditioning and injury prevention training program. Non-parametric analysis of baseline, posttest and four-month follow-up physical performance measures, subjective outcomes, and qualitative follow-up interviews, were reported. Results Significant post-test improvements included: The Dance Functional Outcome Survey (Z= -2.2, p= 0.04), composite Modified Star Excursion Balance Test (Z= -2.2, p= 0.03 bilaterally), Single Leg Hop for Distance (Z= -2.02, p= 0.04), and Upper Extremity Closed Kinetic Chain Test (Z=-2.03, p= 0.04). Significant changes from baseline to the four-month follow up remained for: (1) Dance Functional Outcome Survey (Z= -2.2, p= 0.03), (2) Single Leg Hop for Distance (Z= -2.2, p= 0.03), and (3) Modified Star Excursion Balance Test composite maximum reach for the left lower extremity (Z= -2.2, p= 0.03). Conclusion Completing a conditioning and prevention program for professional ballet dancers was related to improved function, balance, hop distance/stability and upper extremity stability. Dancers found the program beneficial, identified barriers to participation, and elucidated factors making the program feasible and successful. More research is necessary to determine the effect of such programs on injury incidence. Level of evidence 3b

Authors: Khoo Kevin J , Gellert Joshua M , Hagen Mia S 
Published: April 2021

Background Ultimate Frisbee is a rapidly growing sport played in all levels of competition in men’s, women’s, and coed divisions. Despite widespread popularity, there remains a lack of research on injury risk and prevalence during a season. Purpose To determine the prevalence of injuries among elite club-level men and women Ultimate Frisbee players and to identify elements associated with injury during a single season. Study Design Descriptive epidemiological study. Methods Voluntary preseason and postseason online surveys were distributed to local elite club-level Ultimate teams in 2019. Surveys assessed players’ lifetime Ultimate-associated injury history, injury status, training regimen, and other related elements. Results Fifty-seven and 84 players were eligible to complete the preseason and postseason surveys, respectively. Prior to the 2019 season, 97% of female respondents and 100% of male respondents reported a previous Ultimate-related injury in their career, with all reporting a prior lower extremity injury. During the 2019 season, 56% of respondents reported being injured, and 12% missed one month or more of the season, with 88% of injured players reporting a lower extremity injury. Men reported more ankle and calf injuries than women, and there was a strong negative correlation between time missed due to injury during the 2018 season and the number of days per week spent weight-training and accumulated training. Conclusion There is a high prevalence of lower extremity injury among elite club-level Ultimate players during a single season and pervasive lower extremity injury history may contribute to high injury prevalence. Observed injury patterns suggest targeted interventions including Nordic Hamstring Exercises and balance and proprioceptive training may decrease injury risk. Further research into this topic is needed to help reduce injury in these athletes. Levels of Evidence Level 3.
