Accretion Disk Luminosity for Black Holes Surrounded by Dark Matter with Tangential Pressure
Authors: Boshkayev K. , Konysbayev T. , Kurmanov Ye. , Luongo O. , Malafarina D. 
Published: September 2022

Abstract
We study the motion of test particles in the gravitational field of a Schwarzschild black hole surrounded by a spherical dark matter cloud with nonzero tangential pressure, and compute the luminosity of the accretion disk. The presence of nonvanishing tangential pressure allows us to mimic the dark matter’s angular momentum, while still considering a static model, which simplifies the mathematical framework. We compare the numerical results of the influence of dark matter on the luminosity of the accretion disks around static supermassive black holes with the previously studied cases of isotropic and anisotropic pressures. We show that the flux and luminosity of the accretion disk in the presence of dark matter are different from the case of a Schwarzschild black hole in a vacuum, and highlight the impact of the presence of tangential pressures.
Increasing the Prediction Power of Preterm Labor using Interleukin 6 and Fetal Fibronectin as Alarming Signals in Symptomatic Patients
Authors: Hussain Amal Abdul Muhsen , Sharif Yasamin Hamza 
Published: September 2022

Background: Giving birth at preterm is considered as a bothering problem to both healthcare systems and pregnant women around the world, causing alarming levels of mortality. To avoid this issue, certain biological markers can be employed for early detection to predict the occurrence of the PTD (PTD) ahead of time for giving better medical care to the pregnant women who at risk of PTD.
Objective: The current study was performed to evaluate the power of using interleukin-6 (IL-6) and fetal fibronectin (fFN) present in the cervicovaginal fluid (CVF) as predictors of the symptomatic PTD patients.
Patients & Methods: In this study, 91 pregnant hospital attendees (24-34 weeks; 18-45 years old) with suggested PTD symptoms, such as abdominal pain and uterine contraction and with cervical length of less than 25mm, were participated. To detect IL-6 and fFN, vaginal swabs were collected for performing an ELISA test to later follow up with the patients within 48hrs, seven days, and 14 days from the first day of admission to the hospital.
Results: No significant association between PTD with patients age, parity, BMI, and gestational age, but significant association with previous history of PTD. There was significant association between PTD and increase the level of CVF fFN and IL-6 with best cut-off value for CVF fFN is(>45ng/ml) with (95%CI of 0.763-0.918) and accuracy of 85.2% with a sensitivity of 73.1% and specificity of 95.6% which is of high significant value (P≤0.01).While CVF of IL-6 (>231pg/ml) with (95% CI of 0.630- 0.820), with accuracy of 73.3%, sensitivity of 50% and specificity of 96.9% which was statistically significant finding (P≤0.01).The predictive value of combined fFN and IL-6 in women at risk of preterm labor was 84.6% with sensitivity 84.6%,specificity 92.3%, positive predictive value (PPV) 81.5%, negative predictive value (PPV) 93.8% and accuracy of 90.1%.
Conclusion: Each of fFN or IL-6 located in the CVF may provide a strong predictor of PTD; however, this prediction capability may provide an even stronger signal of detecting PTD ahead of time if both biomarkers requested at the same time.

Published: September 2022

Background
Health care professionals (HCPs) performing tracheostomies in patients with COVID-19 may be at increased risk of infection.

Objective
To evaluate factors underlying HCPs’ COVID-19 infection and determine whether tracheostomy providers report increased rates of infection.

Methods
An anonymous international survey examining factors associated with COVID-19 infection was made available November 2020 through July 2021 to HCPs at a convenience sample of hospitals, universities, and professional organizations. Infections reported were compared between HCPs involved in tracheostomy on patients with COVID-19 and HCPs who were not involved.

Results
Of the 361 respondents (from 33 countries), 50% (n = 179) had performed tracheostomies on patients with COVID-19. Performing tracheostomies on patients with COVID-19 was not associated with increased infection in either univariable (P = .06) or multivariable analysis (odds ratio, 1.48; 95% CI, 0.90–2.46; P = .13). Working in a low- or middle-income country (LMIC) was associated with increased infection in both univariable (P &lt; .001) and multivariable analysis (odds ratio, 2.88; CI, 1.50–5.53; P = .001).

Conclusions
Performing tracheostomy was not associated with COVID-19 infection, suggesting that tracheostomies can be safely performed in infected patients with appropriate precautions. However, HCPs in LMICs may face increased infection risk.

En la presente investigación, el objetivo consistió en identificar características que se relacionan con el manejo de la cultura financiera y aspectos en los cuales existen diferencias a partir del género. El método empleado es cuantitativo de corte transversal con alcance descriptivo y correlacional, las personas encuestadas fueron 322. Entre los resultados relevantes que se encontraron están: las mujeres perciben el éxito en razón de factores no relacionados con el dinero, a diferencia de los hombres. Se concluye que las mujeres tienden a experimentar mayor aversión al riesgo, por ello, les es más complejo tener un adecuado desempeño en sus finanzas, caso contrario a los hombres, que tienden a presentar una mayor disposición al riesgo. A la vez, se identificó que las mujeres cuentan con poca habilitación para contar con servicios bancarios debido a su papel social, pues como cuidadoras tienden a priorizar la parte personal.
Abstract
The objective of this research consisted of identifying characteristics relating to financial cultural management and aspects in which differences based on gender existed. A quantitative cross-sectional method was used with a descriptive and correlational scope, 322 people were surveyed. Among the most outstanding results found are: women perceive success as factors which are not related to money, as opposed to men. We conclude that women tend to experience greater reluctance towards risk, consequently it is more complex for them to have adequate performance in their finances, on the contrary, men tend to present greater disposition towards risk. We also identified that women have little availability to banking services due to their role in society, since as caregivers, they tend to prioritize personal aspects.

Published: September 2022

<p align="justify">The phenomenon of population growth is not in line with housing growth in Indonesia, which is the problem in this research. Besides, the current concept of homeownership still tends to use a conventional pattern based on <em>ribawi</em>, which is an obstacle for a Muslim to own a house. The purpose of this study is to determine the strategy of developing the Islamic property business from internal and external factors. The research method used is a quantitative method with data analysis techniques using the SWOT matrix analysis of IFAS (Internal Strategic Factors Analysis Summary) and EFAS (External Strategic Factors Analysis Summary). The population in this study were developers in the Greater Bandung area and the sampling used the convenience sampling method with a total sample of six expert respondents who were ready and willing to become respondents who represented academics, practitioners, and regulators. Based on the SWOT analysis with the IFAS and EFAS matrices, the results show that the position of the Islamic property business is in quadrant 1A, which is experiencing rapid growth. This quadrant shows that the right choice of strategy is rapid growth. The alternative strategy that is used as input is the S-O (Strength-Opportunities) business strategy so that the development strategy formulated is to use all strengths to seize and take advantage of the greatest possible opportunities. This research implies that the existence of business development efforts through SWOT analysis can strengthen the strategy to increase Islamic property and overcome the buying and selling of homeownership that is not yet following Islamic values.</p>
