Authors: Магомедюсуф Владимирович Гасанов, 
Published: January 2023

В настоящей работе проводится исследование некоторого класса дифференциальных уравнений с подвижными особенностями. Приводится обобщение полученных ранее результатов исследования, а именно, теоремы существования и единственности решения рассматриваемого класса уравнений на комплексную область. Получена структура аналитического приближенного решения и априорные оценки погрешности. Данные оценки были оптимизированы с помощью апостериорных. Теоретические положения были протестированы с помощью численного эксперимента.
In this paper, we study a certain class of differential equations with moving singularities. A generalization of the previously obtained results of the study, namely, the existence and uniqueness theorem for the solution of the considered class of equations, to the complex domain is given. The structure of the analytical approximate solution and a priori error estimates are obtained. These estimates were optimized using post hoc estimates. Theoretical provisions were tested using a numerical experiment.

Abstract
Upcoming James Webb Space Telescope observations will allow us to study exoplanet and brown dwarf atmospheres in great detail. The physical interpretation of these upcoming high signal-to-noise observations requires precise atmospheric models of exoplanets and brown dwarfs. While several 1D and 3D atmospheric models have been developed in the past three decades, these models have often relied on simplified assumptions like chemical equilibrium and are also often not open-source, which limits their usage and development by the wider community. We present a Python-based 1Dl atmospheric radiative-convective equilibrium (RCE) model. This model has heritage from the Fortran-based code, which has been widely used to model the atmospheres of solar system objects, brown dwarfs, and exoplanets. In short, the basic capability of the original model is to compute the atmospheric state of the object under RCE given its effective or internal temperature, gravity, and host-star properties (if relevant). In the new model, which has been included within the well-utilized code-base PICASO, we have added these original features as well as the new capability of self-consistently treating disequilibrium chemistry. This code is widely applicable to hydrogen-dominated atmospheres (e.g., brown dwarfs and giant planets).

Abstract
Stars that interact with supermassive black holes (SMBHs) can be either completely or partially destroyed by tides. In a partial tidal disruption event (TDE), the high-density core of the star remains intact, and the low-density outer envelope of the star is stripped and feeds a luminous accretion episode. The TDE AT 2018fyk, with an inferred black hole mass of 107.7±0.4
M
⊙, experienced an extreme dimming event at X-ray (factor of >6000) and UV (factor of ∼15) wavelengths ∼500–600 days after discovery. Here we report on the reemergence of these emission components roughly 1200 days after discovery. We find that the source properties are similar to those of the predimming accretion state, suggesting that the accretion flow was rejuvenated to a similar state. We propose that a repeated partial TDE, where the partially disrupted star is on an ∼1200 day orbit about the SMBH and periodically stripped of mass during each pericenter passage, powers its unique light curve. This scenario provides a plausible explanation for AT 2018fyk’s overall properties, including the rapid dimming event and the rebrightening at late times. We also provide testable predictions for the behavior of the accretion flow in the future; if the second encounter was also a partial disruption, then we predict another strong dimming event around day 1800 (2023 August) and a subsequent rebrightening around day 2400 (2025 March). This source provides strong evidence of the partial disruption of a star by an SMBH.

Authors: Kamdem Emmanuel , Livian Yves-Frédéric 
Published: January 2023

Cet article analyse un retour d’expérience pratique sur l’enseignement de l’éthique des affaires, dans un cursus académique en management au Cameroun. Le problème est l’adaptation, en contexte camerounais, d’un enseignement emprunté à d’autres contextes (européen et nord-américain). L’objectif est d’explorer les possibilités de contextualisation de cet enseignement. L’article présente successivement le retour d’expérience, la revue de littérature et la méthodologie qualitative longitudinale, les résultats, la discussion. Ces résultats révèlent deux réactions paradoxales de quelques étudiants qui ont suivi cet enseignement : la résistance pendant la formation académique et l’appropriation quelques années plus tard. Les discussions montrent quatre principaux impacts (pédagogique, managérial, sociétal et théorique).
Peri-Operative Predictors of Postoperative Bleeding and Sepsis after Percutaneous Nephrolithotomy
Authors: Rajeevan Ambala Tharakkal , Gopalakrishnan Midhun P 
Published: January 2023

Introduction:
Percutaneous nephrolithotomy (PCNL) is the most common minimal access method used for the management of large renal and pelvic stones. The two most common complications after PCNL are bleeding and sepsis. In this context, we did this study to find out perioperative predictors of postoperative bleeding and sepsis after PCNL.

Materials and Methods:
We conducted this study on 110 patients who came for PCNL at our institute from March 1, 2018 to August 31, 2019. Data were collected using a pro forma, and the same analyzed by appropriate statistical methods using the SPSS software.

Results:
The perioperative factors correlated to postoperative bleeding were stone size, density of stone, Guy's stone score, size of Amplatz sheath used, number of working tracts created, and duration of surgery. On regression analysis factors which were predictive of postoperative bleeding were size of Amplatz sheath and number of working tracts created. Peri-operative factors correlated with postoperative sepsis were body mass index of the patient, preoperative total count, density of stone, preoperative pyuria, preoperative positive urine culture, superior calyceal puncture, postoperative total leukocyte count, and postoperative fever within 24 h. The factors which were predictive of postoperative sepsis were preoperative pyuria, preoperative urine culture, superior calyceal puncture, and postoperative fever on regression analysis.

Conclusion:
This study shows perioperative predictors of postoperative bleeding and sepsis after PCNL. Out of 43.63% total complications, 20% were major and 23.63% minor complications.
Association of salivary cortisol and psychological burden in patients with oral cancer and oral potentially malignant disorders: A prospective study
Authors: Kumar Sumit , Kumar Kapila , Singh Babita , Mehrotra Divya , Mahdi Abbas A. 
Published: January 2023

Abstract

Introduction:
This study aimed to find an association between psychological burden (in terms of depression, anxiety, and stress) and salivary cortisol among oral cancer (OC) and oral potentially malignant disorder (OPMD) patients at various time frames.

Methods:
In total, 50 patients with OC and OPMD were studied after their informed consent along with 30 healthy controls. Depression, anxiety, and stress scale-21 (DASS-21) was administered and saliva was collected (non-invasively) at different stages including the time of diagnosis, one and three months after intervention (medical or surgical). To avoid diurnal variation, saliva was collected twice (morning and evening). To assess the linear relationship between depression, anxiety, and stress with salivary cortisol, a partial correlation was calculated.

Results:
Comparison of salivary cortisol levels among control, OC, and OPMD groups showed a statistically significant difference in both morning and evening values at different point of time intervals. Higher values of salivary cortisol were observed in OC patients (both morning and evening) in comparison to the OPMD or control group. A positive correlation was discerned between stress and salivary cortisol in both OPMD and OC patients, while no association was found for depression and anxiety domains.

Conclusion:
The measurement of salivary cortisol effectively demonstrates raised stress levels in OPMD as well as OC patients. Therefore, it is recommended to institute stress management interventions in the patients as part of the treatment of OPMD and OC.
Does red blood cell distribution width predict prognosis in metastatic renal cell carcinoma patients using first-line vascular endothelial growth factor receptor tyrosine kinase inhibitor therapy?

Published: January 2023

Abstract

Aim:
It is red cell distribution width (RDW) that has been reported to show an inflammatory response which has been studied recently. The aim of this study is to investigate whether the pre-treatment RDW in patients using first-line vascular endothelial growth factor tyrosine kinase inhibitor (VEGFR TKI) with the diagnosis of metastatic renal cell carcinoma (mRCC) predicts treatment response and is a prognostic factor or not.

Methods:
About 92 patients diagnosed with mRCC who were being treated with sunitinib or pazopanib in the first line between January 2015 and June 2021 were included in the study. The patients were divided into 2 groups, as being ≤15.3 and >15.3, according to the RDW cut-off value calculated by ROC analysis.

Results:
The mOS of patients with a RDW of ≤15.3% was 45.0 (30.0–59.9) months, and of 21.3 (10.4–32.2) in those with a RDW of >15.3%. This difference was statistically significant (p < 0.001). In the group of patients with a RDW of ≤15.3, median progression free survival (mPFS) (38.04 [16.3–59.7] months) was found to be significantly higher than those with a RDW of >15.3 (17.1 [11.8–22.5] months) (p = 0.04). In multivariate analysis, RDW level (≤15.3, >15.3), was determined to be prognostic markers (p = 0.022).

Conclusion:
In mRCC patients, the RDW value measured before first-line VEGFR TKI therapy is an independent prognostic marker.
Reading Jane Austen and Emily Dickinson: A Personal essay
Authors: Lewis Desiree 
Published: January 2023

This essay critically responds to recent calls to decolonise the classics. In rejecting claims about the inherent value of certain literary works, I unravel my socially situated reading and responses, and therefore counter assumptions that literary value or acts of reading can be universalised. I reflect on personal encounters with Jane Austen’s novels and Emily Dickinson’s poetry, demonstrating how this generated my cognitive, sensory and imaginative growth. Analysed memories of discovering and first reading particular works are connected to a critique of prescriptive decolonial discourse. The essay illustrates this by focusing on readers’ embodied encounters with certain books, affective responses and heterogeneous subject positions. These can lead to their finding emotionally satisfying, edifying and inspirational meanings – irrespective of the historical, geopolitical or cultural worlds delineated by the works’ authors.

Authors: Rugumisa Bernadether T , Sangeda Raphael Z , Bongcam-Rudloff Erik , Massawe Siriel N , Lyantagaye Sylvester L 
Published: January 2023

Background: Neonatal period is a critical period in a child’s heath because it is associated with higher risk of adverse health outcomes. The objective of this study was to assess common adverse health outcomes and compare the risk of such outcomes between preterm and term neonates, in Tanzania.
Methods: This was a case-control study involving infants admitted at Muhimbili National Hospital between August and October 2020. About 222 pairs of preterm and term infants were followed until discharge. Logistic regression was used to compare risk of health outcomes. Statistical significance was achieved at p–value < 0.05 and 95% confidence interval.
Result: Preterm neonates had increased risk of mortality (OR = 7.2, 95% CI: 3.4-15.1), apnea (OR = 4.7, 95% CI: 3.4 – 15.1), respiratory distress syndrome (OR = 10.9, 95% CI: 6.1 – 19.6), necrotizing enterocolitis (OR = 5.5, 95% CI: 1.2 – 25.3), anemia (OR = 4.3, 95% CI: 2.8 – 6.6), pneumonia (OR = 2.7, 95% CI: 1.6 – 4.6) and sepsis (OR = 2.6, 95% CI: 1.7 – 3.9). No difference in risk of intraventricular hemorrhage, patent ductus arteriosus and jaundice was observed.
Conclusion: For promoting neonates' health, prevention and treatment of the higher risk adverse neonatal outcomes should be prioritized.
Results of the performance of automated GeneXpert in childhood tuberculosis in Addis Ababa, Ethiopia: a retrospective cross-sectional study
Authors: Genetu Yiheyis , Belay Bethelhem , Abebe Workeabeba 
Published: January 2023

Background: Approximately 81% of all childhood tuberculosis cases occur among 22 high-burden countries and Ethiopia ranks eighth among these high burden countries. The GeneXpert Mycobacterium tuberculosis DNA and resistance to rifampicin (MTB/RIF) test can detect pediatric tuberculosis and its multidrug-resistant form with very high sensitivity and specificity, but limited data exists on its use in our country. We aimed to evaluate the effectiveness of the GeneXpert assay in comparison to children with a clinical diagnosis of Tuberculosis.
Methods: A descriptive retrospective study on 144 TB-diagnosed children younger than 15 years was conducted at Tikur-Anbessa specialized hospital and Yekatit 12-referral hospital, pediatrics departments, Addis Ababa, Ethiopia. The performance of the GeneXpert test was evaluated by re-vising the charts of patients who have begun anti-tuberculosis treatment. We extracted information from the chart review of 144 eligible children who were diagnosed with tuberculosis and began anti-TB treatment from February 2014 to July 2016.
Result: In the study, 144 patients with clinical diagnosis of tuberculosis were included, and 23% of them also had concurrent HIV infection. Equal numbers of male and female were present; 48.6% were from Addis Ababa. Thirty-four patients (23.6%) were missing their childhood vaccinations. The GeneXpert assay detected disease in only 24 (16.7%) of clinically diagnosed pediatric tuberculosis patients.
Conclusion: Although the GeneXpert assay is helpful in the diagnosis of pediatric tuberculosis, most patients were still receiving treatment even after a negative GeneXpert test, necessitating the need for a more sensitive test.
Pattern, outcome, and associated factors of renal disease among hospitalized children at public hospitals in Bahir Dar Town, North-Western Ethiopia
Authors: Simeneh Yenework Tafere , Yimer Yalemwork Anteneh , Yadita Zemenu Shiferaw 
Published: January 2023

Background: Renal diseases are major causes of morbidity and mortality in hospitalized pediatric patients. Data on the spectrum of renal disorders and their outcomes are scarce in Ethiopia, in the Amhara region particularly. Hence, this study aimed to assess the pattern, outcome, and associated factors of renal disease among hospitalized pediatric renal patients in the Amhara region, North-west Ethiopia, 2020.
Methods: Institution-based review of medical records of renal disease subjects was conducted from September 1-15, 2020. All (107) pediatric patients who were diagnosed and hospitalized with renal disease from January 1/2019 to August 30/2020 were studied. A checklist was used to review medical records. Analysis was done using the SPSS version 23. Descriptive and summary statistics were carried out. Chi-squared test was used to assess the association between dependent and independent variables.
Result: Glomerulonephritis was the common cause of renal admissions (59.8%) and 40% of them had renal failure. Multi-organ failure and sepsis were causes of death for 12.1% of patients. Acute kidney injury (X2=4.484, p <0.05), chronic kidney disease (X2=6.617, p< 0.05), multi-organ failure (X2=48.57, p< 0.05), Sepsis (X2=45.29, p< 0.05), hospital stay >2 weeks (X2=23.2, p<0.05), electrolyte abnormalities (X2=17.87, p<0.05), and seizure (X2=45.15, p<0.05) had statistical as-sociations with poor outcome of renal disease.
Conclusion: Glomerulonephritis was the common cause of renal admissions. Sepsis and multi-organ failure were common causes of death. The complications, hospital stay >2 weeks, electrolyte abnormality, and seizure had an association with the outcome of renal disease. Hence, this study suggests that early diagnosis and management of renal failures and complications, and shortening hospital stay enhance the outcome of renal disease.
Assessment of knowledge and practice of gynecology/obstetrics residents and midwives towards essential newborn care At Tikur Anbessa Specialized Hospital, Addis Ababa University, Ethiopia
Authors: Debie Degu , Belay Bethlehem , Tesfaye Melat 
Published: January 2023

Background: A time-bound and chronologically ordered series of medical interventions that a baby receives at birth are referred to as the "essential newborn protocol." This period of immediate care is critical for the babies' subsequent well-being and adaptation. However, there are still reports of health workers lacking good knowledge and practice with newborn care, which was not investigated in our hospital.
Methods: A hospital-based cross-sectional study was conducted in TASH with 114 selected gynecology and obstetrics residents and midwives. Using the SPSS version 25 software package, continuous data were described using the mean and standard deviation, while categorical data were de-scribed using frequency and percentage. To identify factors related to knowledge and practice, multivariable binary logistic regression analyses were used.
Result: Eighty-eight residents and 26 midwives were included. Nearly a quarter (24.6%) of participants had good knowledge about essential newborn care. Regarding knowledge level by profession, 31.8% of the residents had good knowledge of essential newborn care, and all the midwives had poor knowledge. The odds of having good knowledge of ENC were 96.3% lower for first-year residents and 90.5% lower for second-year residents as compared to year four. Untrained participants had an 84 percent lower chance of having good knowledge of essential newborn care than trained participants. Regarding practice level by profession, more than two-thirds of 68 (77.3%) residents and 21 (80.8%) midwives had sufficient skill in essential newborn care.
Conclusion: A substantial number of healthcare providers lacked essential newborn care knowledge and practice. The availability of service or on-the-job training, as well as the year of residency, were factors influencing newborn care knowledge. In-service training, encouraging supervision, and provisions should be reinforced to improve newborn care activities.
Household food insecurity and food safety knowledge, attitude, and practice of mothers with outpatient under-five children at Cure Hospital, Addis Ababa
Authors: Disassa Hiwot , Ashenafi Mogessie 
Published: January 2023

Foodborne illnesses result in life-threatening conditions among vulnerable members of households. Proper knowledge, attitude and practices in food safety issues are important to curb the damage caused by these illnesses at household level. This study examined the food insecurity experiences and food safety knowledge, attitude, and practice (kap) of mothers having outpatient children in Cure Hospital, Addis Ababa, Ethiopia. A sample size of 210 randomly selected mothers was considered for this study. A cross-sectional study was carried out using semi-structured questionnaire to collect data on food insecurity experiences and food safety knowledge, attitude and practice of respondents. Data was analyzed using descriptive statistics. Most respondents were married (68%), had primary or secondary level education (62%), had one or two under-five children (71%), and 52% had monthly income between etb 500 and 2500. Between 70% and 80% of the respondents experienced anxiety or uncertainty of not having enough food for household members or reduced quality or quantity of food they ate in the previous thirty days. Around 58% experienced hunger during the same period. The knowledge of mothers in food safety (food handling, personal hygiene and water sanitation) was generally poor (<60%). The level of positive attitudes of mothers towards food safety was also poor (<60%). Appropriate practices, particularly in food handling and personal hygiene were also very poor. As foodborne illnesses can be fatal to vulnerable members of a household, a thorough training to mothers in food safety issues is recommended.
