An extremely preterm male infant at 25.1 weeks gestation developed extreme hyperleukocytosis on Day of life (DOL) 3, with a peak white blood cell (WBC) count of 146.5 ×109/L on DOL 5. The patient was admitted to the NICU due to prematurity, respiratory distress, and suspected sepsis. Laboratory analyses were done to exclude sepsis with a leukemoid-like reaction, Down syndrome by karyotype, leukemia, or other myeloproliferative disorders. After a meticulous investigation and ruling out the most common causes of leukocytosis in preterm neonates, we concluded that the hyperleukocytosis in this extreme premature infant was likely caused by maternal chorioamnionitis and fetal funisitis as reported by placental pathology.
We present this rare case of hyperleukocytosis in an extremely premature infant to highlight the importance of a thorough investigation, including sources of infection in the mother's history and placental pathology report, to determine the cause of hyperleukocytosis in the preterm neonates.

Published: July 2022

El COVID-19 provocó cambios en el estilo de vida de las personas, al ser una enfermedad altamente contagiosa y con elevada mortalidad, los gobiernos optaron por medidas como el aislamiento y distanciamiento social, lo cual ocasionó incrementos en las cifras de personas con trastornos emocionales. De ahí que, el objetivo del presente estudio fue reconocer los síntomas emocionales percibidos por los padres de familia en niños mexicanos derivados por la pandemia de COVID-19. Es una investigación transversal y descriptiva. Participaron 614 padres de familia (edad M=35.3) quienes evaluaron a sus hijos. La muestra de niños fue de 1,273 (edad M=13.1 años). Se empleó la Encuesta Digital Efectos Emocionales Derivados por COVID-19 en Niños. Los resultados mostraron que los padres reconocieron que un 17% de los niños presentó al menos un indicador de trastornos psicosomáticos, 42% con depresión, 48% con ansiedad y 52% con problemas de conducta. Lo anterior, coincide con la evidencia en otros estudios al encontrar efectos negativos de la pandemia en el área emocional de las personas. A partir de lo anterior, se concluye que es imperante la necesidad de crear acciones para favorecer la resiliencia en los niños con el propósito de mejorar su calidad de vida.

Investigaciones han divulgado datos sobre la violencia en las relaciones de noviazgo indicando que como fenómeno social ha incrementado convirtiéndose en problema social. Dentro de la familia, el ambiente de violencia que los padres tengan va a influir en los hijos adolescentes, manifestándose en sus relaciones de noviazgo como ansiedad, frustración, depresión y enojo. Objetivo. Identificar si ha incrementado la violencia en la relación de noviazgo adolescente en los tiempos actuales de la COVID19 considerando como referencia el tipo de relación familiar. Material y método. Con enfoque cualitativo, la investigación fue descriptiva y mediante el método de “bola de nieve” se seleccionó a 8 adolescentes quienes estaban en relación de noviazgo. Se les aplicó una entrevista semiestructurada para conocer y comprender su relación de familia y relación en su noviazgo. Resultados. En cuanto a su relación familiar los adolescentes argumentaron que la relación que ven entre sus padres es mala. Sobre su relación en el noviazgo la mayoría consideró que tenían una relación positiva; sin embargo, sí identificaron tener problemas. Todos negaron vivir violencia en su relación a pesar que todos afirmaron que su pareja los había insultado o humillado. Conclusión. Sí existe una relación entre el antecedente del tipo de relación familiar, el incremento de la violencia en la relación de noviazgo adolescente y el confinamiento de los tiempos actuales de la COVID19.

Translation of the Qur'an between text and ideology
Orientalism starts as a religious and cultural movement searching in the Arab world to know about Islam, culture, history, and tradition. They tried hard to dig deeply into Islam through the Quran, Sunnah, all these efforts were due to the strategic geographical position of the Arab world. Orientalists became very fluent in Arabic,
The Article is investigating translations of the Quran into English with a focus on the intervention of the ideological factor taking into account the influence of Orientalist ideology. The ideology as in the case of manipulation school in translating Islamic texts by orientalists. The research seeks to examine the relation between ideology and translation. It is true that the Orientalist scholars, although not altogether free from biased thinking, have contributed a lot, so far as their intellectual endeavors are concerned. The paper highlights the features of the Orientalist translation, objectives, sources, motives, structure, and methods. The paper concludes that most orientalist translators are consciously or unconsciously influenced by religious, cultural, social ideologies when they translate Quranic text. The study shows that we need to develop more studies in the field of an ideological factors in the translation of the Quran.

Background: Globally, major depression is the primary cause of disability, where a large part of cases is reportedamong the working-class.Methods: We conducted comparative cross-sectional study with 8-week observation includes mindfulnessmeditation, curcumin supplementation and sunlight exposure (MCS program) among mildly depressed officeworkers of both sexes - 34 in observed group (OG) and 34 in control group (CT). At baseline, day 30, andday 60, participants were compared in terms of (a) vitamin D, (b) brain-derived neurotrophic factor (BDNF), (c)interleukin-6 (IL-6), and (d) depression scores using PHQ-9. ELISA were performed for all serum samples.Results: The rates of increase of vitamin D in both day 0, 30 and day 30, 60 intervals were significantly higher inOG (p<0.05). BDNF levels varied extensively between the groups. IL-6 means were significantly lower in OG atday 30 than in CG (p<0.05). Depression scores rate of change demonstrated appreciable fall in day 0, 30 intervaland stayed down to day 60 in OG. Significantly, lower depression scores were observed for OG at both day 30 andday 60 (p<0.05).Conclusion: MCS program resulted in significant decreases in depression scores and some of its related biomarkers,
thus can be a sustainable and cost-effective approach to alleviating psychological depression among the working-class.

Introduction: COVID-19 the deadly virus, was declared a pandemic by WHO in March, 2020 because of itsvirulent nature. It has been a piece of work to understand the mechanism of action and the disease pathology ofthe virus, due to its novel origin. The quality of healthcare is seen to be severely degrading during these times. Thetwo different types of COVID tests that are commonly available in the facility are RTPCR and Rapid Antigen Testor RAT. These help to identify whether the person is infected with the virus or not. With the current managementbeing successful in majority of the cases, we should also consider strengthening the existing modalities.Objective: To find the prevalence of COVID-19 patients and study their clinical course and outcomeMaterial and methods: Data regarding covid-19 patients was collected on basis of demographic profile by usinggoogle foms questionnaire at Dr. D.Y. Patil Hospital, Navi Mumbai.Results: A total of 500 patients were included in the present study with male preponderance with 61.4%. 99%patients were tested COVID positive, 73.2% had a history of exposure to COVID patients, 80% had a positive travelhistory, 99% lab tests were positive. 50.4% duration of the treatment lasted for 7-14 days. 67.6% were treated inthe wards, whereas, the remaining 32.4% were treated in the ICU. 19.6% patients required mechanical ventilatorsupport. 51% patients required oxygen therapy. 80.2% did not require intubation. All the patients were onantibiotics, and majority of the patients, i.e. 99.8% were on immuno-boosters as well. Antivirals were administeredin 80.6%. 82.8% were discharged with a negative swab. Out of the 17.2% patients with positive swab, mortality wasseen in 6.2% patients. 3.4% patients were referred to different centers, while the treatment of the remaining 7.6%patients was continued for a longer period of time.Conclusion: A stepwise perspective of non-pharmaceutical interventions, screening and testing procedures,implementation and compliance to distancing, hygiene measures and use of masks at airports, railway stations,other public places with pragmatic testing and tracing are effective measures that can be implemented. Worldwide
numerous clinical trials are taking place for the treatment and prevention of COVID-19. Although, there is a rapidcomprehensive expansion in regard to COVID-19 and few agents appear to be promising, there are no definitelyproven effective therapies at this time.

Investigating Particle Acceleration by Dynamic Small-scale Flux Ropes behind Interplanetary Shocks in the Inner Heliosphere
Authors: Van Eck Keaton , le Roux Jakobus , Chen Yu , Zhao Ling Ling , Thompson Noah 
Published: July 2022

Abstract
We recently extended our Parker-type transport equation for energetic particle interaction with numerous dynamic small-scale magnetic flux ropes (SMFRs) to include perpendicular diffusion in addition to parallel diffusion. We present a new analytical solution to this equation assuming heliocentric spherical geometry with spherical symmetry for all SMFR acceleration mechanisms present in the transport theory. With the goal of identifying the dominant mechanism(s) through which particles are accelerated by SMFRs, a search was launched to identify events behind interplanetary shocks that could be explained by our new solution and not classical diffusive shock acceleration. Two new SMFR acceleration events were identified in situ for the first time within heliocentric distances of 1 astronomical unit (au) in Helios A data. A Metropolis–Hastings algorithm is employed to fit the new solution to the energetic proton fluxes so that the relative strength of the transport coefficients associated with each SMFR acceleration mechanism can be determined. We conclude that the second-order Fermi mechanism for particle acceleration by SMFRs is more important than first-order Fermi acceleration due to the mean compression of the SMFRs regions during these new events. Furthermore, with the aid of SMFR parameters determined via the Grad–Shafranov reconstruction method, we find that second-order Fermi SMFR acceleration is dominated by the turbulent motional electric field parallel to the guide/background field. Finally, successful reproduction of energetic proton flux data during these SMFR acceleration events also required efficient particle escape from the SMFR acceleration regions.
