Online Learning Resources Enhanced Teaching and Learning of Medical Mycology among Medical Students in Gulu University, Uganda

Background. The burden of serious fungal diseases has significantly increased in the past few decades; however, the number of health-care workers with expertise in the management of fungal diseases remains low, especially in low- and middle-income countries (LMICs). This study aimed to evaluate the use of freely available online teaching material to enhance teaching and learning of medical mycology among medical students in Gulu University Medical School, Uganda. Methods. We conducted a cross-sectional study among second year medical students undertaking Medical Mycology course on antifungal agents in the department of Medical Microbiology and Immunology in the academic year 2017-2018. The materials were synthesized and peer-reviewed by experts in fungal diseases and were made freely available on the Leading International Fungal Education website ( http://www.LIFE-Worldwide.org ). A local faculty in the department delivered the lectures, and pre- and posttest scores were evaluated statistically. Results. Sixty medical students participated in the study of which 78% were male. The average score was 41% for the pretest and 52% for the posttest ( ). There was no significant difference in the scores of males and females. Majority of the students gave an above-average rating for the course material; however, 54% preferred prerecorded videos. Conclusion. Using freely available online materials on medical mycology can enhance teaching and learning of medical mycology. Because of this, there is need to incorporate up-to-date information about the subject into the curriculums of medical schools especially in LMICs.
Obstructive Sleep Apnoea in Pakistan: A Single Tertiary Care Center Experience

Introduction: Considerable interest has been shown in the field of sleep medicine in recent decades. Obstructive sleep apnoea (OSA) is a common condition that remains neglected in most parts of the world. Data are scarce, if any, when it comes to developing countries. We sought to describe the patient population in a single private tertiary care center from such a country. Materials and Methods: A cross-sectional study that included a total of 203 patients over a five-year period was conducted. Polysomnographic studies were conducted in a dedicated sleep laboratory, under the supervision of sleep physicians. Data were described and analyzed based on clinical and self-reported outcomes, as well as polysomnographic characteristics, and compared them between genders and severity. Results: With the participants having an average age of 50.84 years and a BMI of 34.7 kg/m2, the study found that the increase in age and BMI was significantly correlated with an increase in the severity of obstructive sleep apnea in the Pakistani population. There was a significant difference in sleep latency (20.6 min in women vs. 10.8 min in men; p-value = 0.001) and efficiency (63.7% in women vs. 69.8 in men; p-value = 0.02) between the two genders. Decreases in nadir saturation, total sleep time, and sleep latency were also associated with an increase in the level of severity. Conclusion: There is a dire need for Pakistani, and in extension Asian, medical professionals to ramp up their pace to meet the needs of their population with regard to sleep medicine.
Reduction of surface roughness by modification of step-bunched aluminum nitride layers towards step-flow morphology

Conventional aluminum nitride (AlN) template fabrication techniques, like hydride vapour phase epitaxy or AlN growth on patterned sapphire substrates, usually lead to step-bunched template surfaces. The resulting macrosteps cause emission broadening or even multiple-peak characteristics of ultraviolet light-emitting diodes (UV LEDs) fabricated on such AlN templates. In order to reduce these macrosteps and to provide a smoother surface, even without the need of a thick AlN deposition, a two-layer growth procedure is reported here. A three-dimensional (3D) – twodimensional (2D) sequential growth initiates a significant modification of the previous AlN surface morphology and simultaneously limits the evolving tensile strain. A primarily step-bunched surface with a surface roughness root mean square of 1.8 nm is successfully reduced by the two-layer growth procedure down to 0.8 nm, without any film cracking. This distinct roughness reduction of more than 50% is achieved within an AlN thickness of only 1.3 μm. With a smoother surface, the electroluminescence characteristic of a UV LED structure is substantially improved. Instead of a double-peak emission, typical for LEDs grown on step-bunched templates, a single-peak emission and lower spectral width were achieved, indicating the high potential of the suggested two-layer technique for improving performance.

Classification : M 210 A Try to combine more than approaches and competitive strategies to achieve a sustainable competitive advantage

The objective of this research paper is two-fold. The first is a precise reading of the theoretical underpinnings of each of the strategic approaches: "Market approach" for (M. Porter), and the alternative resource-based approach (R B V), advocates for the idea that the two approaches are complementary. Secondly, we will discuss the possibility of combining the two competitive strategies: cost leadership and differentiation. Finally, we propose a consensual approach that we call "dual domination".
The Dark Side of CEO Networks: Evidence from Real Activities Management

We examine the relation between CEO network size and the level of real activities management (RAM). Using the number of social connections to outside executives, directors, and others in similar positions to measure network size, we find that well-connected CEOs associate with higher levels of RAM. Social science theory suggests that this occurs because well-connected CEOs can acquire more information from their social networks to implement RAM effectively. The power and influence and labor market insurance from a large network also reduces the private cost of RAM. Supporting these two channels, we find a stronger positive relation between RAM and CEO network size when the CEO connects with more informed and influential persons and has more reputation to protect in the labor market. In addition, the positive relation concentrates in firms with low CEO share ownership, where a more severe misalignment of interests can occur. We also show that higher but not extreme levels of RAM from a large CEO network degrades the firm’s long-term operating performance, suggesting that large CEO networks have a darker side for firm value.
An Empirical Study on the Role of Educational Human Capital in Improving Economic Efficiency

Under the background of different regional variables, there are differences in the economic effects of human capital. From the perspective of educational human capital, the new normal of economy is taken as the background. Based on 2008 to 2015 provincial panel data in China, this paper first measures the educational human capital and different economic efficiency, and then discusses the effects of educational human capital on technology efficiency, scale efficiency, X efficiency and allocation efficiency, and finally summarizes the difference of the influence of educational human capital on different types of regional economic efficiency. The study found that in the eastern region, the influence of educational human capital on allocation efficiency is most significant; in the central region, the influence of educational human capital on technical efficiency and allocation efficiency is more significant; in the western region, the influence of educational human capital on technical efficiency and allocation efficiency is more significant. And although educational human capital has a positive influence on the improvement of economic efficiency, the significance of the impact is not high, and there are differences with developed countries.

Cellulitis Caused by a Novel Cupriavidus Species Strain J1218 Identified by Whole Genome Sequencing

We report a case of cellulitis caused by a novel Cupriavidus species identified using whole-genome sequence analysis. Subcutaneous tissue biopsies from the left lower leg of a 67-year-old man who suffered from cellulitis were cultured. Round, convex, gray and non-hemolytic colonies were recovered after 72-h incubation. 16S rRNA sequence analysis showed 98.6% similarity with Cupriavidus basilensis DSM 11853(T) in the NCBI database and 99.9% similarity with C. basilensis KF708 in the EzBioCloud database. Genomic analysis using the MiSeq platform (Illumina, USA) and the TrueBac ID database (ChunLab, Korea) revealed that the average nucleotide identity (ANI) of this strain with C. basilensis DSM 11853(T) was 87.6%. The patient was treated with oral cefditoren pivoxil for 9 weeks. This study is the first to report cellulitis caused by Cupriavidus species strain J1218. (Ann Clin Microbiol 2019;22:105 -109)
Structural Modal Analysis and Optimization of SUV Door Based on Response Surface Method

Sensitivity analysis and response surface methods were employed to optimize the structural modal of SUV doors. A finite element numerical simulation model was established and was calibrated by restraint modal tests. To screen out highly sensitive panels, a sensitivity analysis for the thickness of door panels was proposed based on the fifth-order modal frequency of the door. Data points were obtained by a faced central composite design with the design variables from the thickness of the highly sensitive panels, and a second-order explicit response surface function of the fifth-order modal frequency of the vehicle door was established. An optimization model was established according to the response surface method. The final results demonstrate that the modal-frequency matching of the door and body in white was optimized after changing the thicknesses, with a 5.74% material reduction.
Clinical Significance Alberta Stroke Program Early Computed Tomography Score (ASPECTS) And National Institute Of Health Stroke Score (NIHSS) On First Ever Acute Ischemic Stroke Patients

Background The Alberta Stroke Program Early CT Score (ASPECTS) is used to quantify the extent of ischemic lesion in acute ischemic stroke on middle cerebral artery territory. Stroke severity is determined by the extent of ischemic lesion among other factors, which can be quantified using National Institute of Health Stroke Score (NIHSS). NIHSS is a subjective tool with many biases. Knowing the correlation between ASPECTS and NIHSS, clinician could use ASPECTS as secondary method for measuring the severity of acute ischemic stroke. Objectives To find correlation between ASPECTS and NIHSS on acute ischemic stroke patients. Method This was an analytic-descriptive cross-sectional study on first-onset ischemic stroke patient in Neurology Ward of Hasan Sadikin General Hospital admitted from October 2017 – February 2018. Ischemic stroke patients classified using the Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria. ASPECTS is calculated from CT-scan of patients with ischemic stroke involving middle cerebral artery and compared to NIHSS. Statistical significances were calculated with Spearman rank and Kruskal Wallis test with significance if p value < 0.001. Results The total of the 46 subjects, consisting of 10 cases of stroke atherosclerosis of the large arteries (LAA), 22 cases of lacunar stroke, 13 cases of cardioembolic stroke and 1 another cause of stroke were included in this study. ASPECTS in this study (mean ± SD) was 7.54±2.11 and NIHSS in this study (mean ± SD) was 10.47±6.04. We found that cardioembolic stroke subtype had ASPECT score lower than another type of stroke (LAA, lacunar, and undetermined causes) and statistically significant (p<0.001) and had higher NIHSS than another type of stroke (p<0.001) Spearman’s correlation test between ASPECTS and NIHSS show a strong correlation between ASPECTS and NIHSS (r=0.821,p < 0.001) Conclusion There is a strong inverse correlation between ASPECTS and NIHSS score on acute ischemic stroke. The higher the value ASPECTS, it will be the lower value of the NIHSS and ASPECT score had correlation with stroke severity.
The Integrated Quality Analysis of Sediment on BanjirKanal Barat River as the Basis of River Environment Management

There have been many studies on the pollution status of Banjir Kanal Barat (BKB) River; however, many of them are limited to the concentration of metals in the river water and their biodiversity of water biota, and partial analysis. The study aims to analyse the metal concentration in BKB river sediment, its toxic to water biota and the effect on the abundance and diversity of macrozoobenthos. The evaluation of pollution status is conducted with three components integrated approach. The sediments were collected from three sampling stations with three replications. While the community observation included abundance, diversity, evenness and dominance of macrozoobenthos. Toxicity testing had been carried out to observe the inhibition of the growth of Chlorella sp algae in pore water sediments and failure reburial of blood clams into the substrate/sediment. While the evaluation of pollution status was conducted in an integrated three components approach. The results showed that the concentrations of various metals in the sediment were varied. The concentration of metals in sediments were still within natural limits and identical to the reference station that was not polluted. The types of macrozoobenthos were found about nine genera with varying in abundance, diversity index, evenness index, and dominance index. The abundance, diversity index, evenness index, dominance index of macrozoobenthos at all stations were still identical with reference stations, which known was not polluted. Although pore water sediments and sediments from various stations caused inhibition of the growth of Chlorella sp and the failure reburial of blood clams, statistically analysis was not significantly different from the reference station. Overall it can be stated that the sediment quality in those three stations was still excellent, however, they need to be maintained.

Left ventricular fibrosis by extracellular volume fraction and the risk of atrial fibrillation recurrence after catheter ablation.

Background Left ventricular (LV) extracellular volume fraction (ECV) provides prognostic information in patients with variety of cardiomyopathies. However, data on the clinical significance of LV ECV in patients with atrial fibrillation (AF), especially in patients without replacement fibrosis are sparse. This study sought to investigate whether the presence of LV fibrosis identified by cardiac magnetic resonance (CMR) ECV quantification would independently predict the recurrence of AF after first catheter ablation (CA) in patients with AF. Methods A total of 130 consecutive patients who were referred for CA of AF underwent CMR examination prior to ablation. LV function, T1 mapping derived LV ECV, LV late gadolinium enhancement (LGE) were assessed. Patients were followed for arrhythmia recurrence after the CA procedure. Results Of 130 AF patients, 65 patients had paroxysmal AF, and 65 patients had persistent AF. There were 50 AF recurrences over a median follow-up period of 13 months. LV ECV were significantly higher in patients with recurrent AF compared to those with no recurrence (30.4%±3.3% vs. 27.4%±2.9%, P<0.001). In multivariable model, gender (HR: 0.348, 95% CI: 0.174-0.697, P=0.003), body mass index (BMI) (HR: 1.159, 95% CI: 1.050-1.279, P=0.003), AF duration (HR: 1.006, 95% CI: 1.001-1.011, P=0.017), and LV ECV (HR: 1.158, 95% CI: 1.071-1.251, P=0.000) were significantly associated with AF recurrence. In subgroup of patients without LGE, gender, BMI, AF duration and LV ECV were still the independent predictors of AF recurrence. Conclusions LV ECV expansion is associated with AF recurrence after CA and is a strong independent predictor of AF recurrence.
Correlation of metabolic syndrome clinical signs and genetic determinants at children with obese

UNLABELLED: The aim of the work was to study the clinical and genetic factors at children with obese that predispose to the development of MS, and the development of algorithm for generating risk of MS. MATERIALS AND METHODS: Two comparable age and sex groups of children--148 children with obesity and 46--with normal body weight. We assessed anthropometric indices, blood pressure (BP), lipid profile, carbohydrate metabolism, the level of uric acid. 83 children with obesity were genotyped for polymorphisms: I/D gene ACE, G-75A ApoA1, S19W ApoA5, Sstl ApoC3, E2/E3/E4 ApoE and W/R ADRB3. RESULTS: 98,0% of children had abdominal obesity. In 35,8% was identified high blood pressure. In 47,4% was diagnosed hypo-alpha cholesterolemia and/or hypertriglyceridemia (HTG). In 21,0% of children was identified hyperglycemia. 25,7%were suffered from hyperuricemia. Among the genotyped children 57,0% of homo-and heterozygous carriers of D allele ACE gene had high blood pressure. More than half of the holders of 19W-allele ApoA5 (68,5%),--75A-allele of ApoA1 (56,0%), 52-allele of the gene ApoC3 (53,0%), E4-ApoE gene (85,7%), in the heterozygous state had metabolic TG and/or HDL. In 60,3% of the carriers W/W genotype of ADRB3 gene revealed a combination of hyperglycemia with hyperinsulinemia and/or TG. CONCLUSION: As a result of, aiming aimed at early detection of the major manifestations of MS clinical and genetic study was revealed stable combination of constitutional, metabolic and molecular-genetic factors. Based on these data was developed algorithm for forming groups at risk of MS and individual tactics to prevent and/or therapy.
Analytical Study Based Optimal Placement of Energy Storage Devices in Power Systems to Support Voltage and Angle Stability

Larger penetration of Distributed Generations ( DG ) in the power system brings new flexibility and opportunity as well as new challenges due to the generally intermittent nature of DG . When these DG are installed in the medium voltage distribution systems as components of the smart grid, further support is required to ensure a smooth and controllable operation. To complement the uncontrollable output power of these resources, energy storage devices need to be incorporated to absorb excessive power and provide power shortage in time of need. They also can provide reactive power to dynamically help the voltage profile. Energy Storage Systems ( ESS ) can be expensive and limited number of them can practically be installed in distribution systems. In addition to frequency regulation and energy time shifting, ESS can support voltage and angle stability in the power network. This paper applies a Jacobian matrix-based sensitivity analysis to determine the most appropriate node in a grid to collectively improve the voltage magnitude and angle of all the nodes by active/reactive power injection. IEEE 14, 24, and 123-bus distribution system are selected to demonstrate the performance of the proposed method. As opposed to most previous studies, this method does not require an iteration loop with a convergence problem nor a network-related complicated objective function.
Correlation between methylenetetrahydrofolate reductase gene polymorphism and oligoasthenospermia and the effects of folic acid supplementation on semen quality.

Background The present study investigated the correlation between 5,10-methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and oligoasthenospermia, as well as the effects of folic acid supplementation on semen quality. Methods The present study was a case control study. The PCR-chip assay was applied to analyze the distribution characteristics of the frequencies and genotypes of the MTHFR C677T allele in 167 Han Chinese patients with idiopathic male infertility (including 86 patients with oligospermia and 81 patients with asthenospermia) and in 78 males with normal semen parameters. Moreover, homocysteine (Hcy) levels were assessed for the different groups. Semen quality was measured following three months of folic acid supplementation for the oligospermia and asthenospermia groups. Results The cytosine-thymine (CT) genotype (50% vs. 39.5%) and the thymine-thymine (TT) genotype (51.2% vs. 7.7%) carriers in the oligospermia group exhibited significantly higher percentages compared with those of the control group. The percentage of the CT genotype carriers in the asthenospermia group was significantly higher compared with that of the control group (59.3% vs. 50%), while the frequency of the TT genotype was significantly increased (22.2% vs. 7.7%). Furthermore, serum Hcy levels in the oligospermia and asthenospermia groups were significantly higher compared with those of the control group. The data also demonstrated that sperm density increased significantly following three months of folic acid supplementation to patients with oligospermia or asthenospermia. In these patients, the highest increase was noted for the subjects carrying the TT genotype. Conclusions The MTHFR C677T mutation and the elevated Hcy levels are important risk factors for the development of oligoasthenospermia. Folic acid supplementation can significantly improve sperm density.
