On maximal Kn domains for certain families of rational functions
Authors: Kiriyatzkii Jevgenij , Kiriyatzkii Eduard 
Published: June 2020

Let Kn(D) be a class of analytic in domain D functions such that [F(z); z0,...,zn] for any z0,...,zn ∈ D. The domain D is called by maximal Kn-domain of the family T of functions which are analytic in D, if for any neighborhood ε(ψ) of any boundary point ψ of D there exists a function from T which does not belong to Kn(D \smile ε(ψ)). The maximal domain of univalence, i.e., maximal K1 domain was investigated by Bulgarian mathematician L. Chakalov. In this paper as maximal Kn-domains the angular domains are examined. Kn-domains for two special classes of rational functions are established.
An empirical study of the structure of the shortest path tree
Authors: Bloznelis Mindaugas , Radavičius Irmantas 
Published: June 2020

We consider a complete graph on n vertices. Edges of the graph are prescribed random positive weights X1, X2, . . ., Xm. Here m = (n/2). We assume that these random variables are independent and have the common probability distribution with density function f (x), x \geq 0. Given a vertex v let T denote the shortest path tree with root v. Let T1, T2, . . . ⊂ T denote the trees that are obtained from T after removal of the root v. Let N1 \geq N2 \geq N3 \geq . . . denote (ordered) sequence of sizes of these trees. We study statistical properties of this sequence for various densities f and large n.

Authors: O’Callahan Cliff , Te Silena , Husain Aaftab , Rosener Stephanie E. , Hussain Naveed 
Published: June 2020

BACKGROUND AND OBJECTIVES:Little is known about the effect of circumcision on breastfeeding in the hours and days after the procedure. Factors with the potential to negatively impact breastfeeding success in the newborn period may result in higher rates of jaundice requiring phototherapy and formula supplementation, both of which can potentially extend the length of initial hospitalization. Our objective was to determine the impact of circumcision on rates of exclusive breastfeeding, neonatal jaundice requiring phototherapy, and length of stay at hospital discharge immediately after birth.METHODS:Term male newborn infants whose mothers intended to exclusively breastfeed were included in this retrospective cohort. Bivariate analysis and multivariate logistic regression modeling were used to evaluate target behaviors, comparing infant boys who were circumcised with those who were uncircumcised.RESULTS:Of the 1109 breastfed male newborns included, 846 (76.6%) were circumcised. There was no significant effect of circumcision status or circumcision timing on the rate of in-hospital formula supplementation. There were no differences in peak bilirubin levels, phototherapy requirement, or length of hospital stay for male newborns based on circumcision status.CONCLUSIONS:Circumcision did not affect the rate of exclusive breastfeeding, neonatal jaundice, phototherapy requirement, or length of hospital stay in this retrospective analysis of breastfed male newborns.

Published: June 2020

BACKGROUND AND OBJECTIVES:
Rehabilitation after a child’s traumatic brain injury (TBI) occurs in hospital, community, and school settings, requiring coordination of care and advocacy by parents. Our objective was to explore Hispanic parents’ experiences during child’s transitions of care after TBI.

METHODS:
We conducted this qualitative study using semistructured interviews. We used a convenient sample of Hispanic parents of children hospitalized for a TBI in a single level I trauma center. Thematic content analysis using iterative deductive coding and triangulation with clinical data was conducted to identify barriers and facilitators for transitions of care.

RESULTS:
Fifteen mothers, mostly from rural areas and with limited English proficiency, participated in the study. Obtaining outpatient rehabilitation was difficult. Barriers included lack of therapists and clinical providers close to home, worsened by insufficient transportation and other support resources; poor understanding of child’s illness and treatments; and suboptimal communication with clinicians and school administrators. Facilitators included interpreter use, availability of Spanish written information, and receipt of inpatient rehabilitation. Parents of patients discharged to inpatient rehabilitation reported that observing therapies, receiving school discharge plans by hospital-teachers, and coordination of care were facilitators to access outpatient treatments and to support school return. Parents of children discharged from the hospital from acute care reported need of legal services to obtain school services.

CONCLUSIONS:
Hispanic parents, especially those with limited English proficiency, can face significant challenges accessing TBI outpatient rehabilitation and school resources for their children. Although barriers are multifactorial, efforts to improve communication, parent’s TBI education, and care coordination during transitions of care may facilitate a child’s reintegration to the community and school.
Potential Use of Cellular Stromal Vascular Fraction In Post-COVID-19 Pulmonary Injury and Adult Respiratory Distress Syndrome
Authors: Alexander Robert W. 
Published: June 2020

A coronavirus (nCoV-2) has caused a worldwide pandemic, beginning in Wuhan, China. Patient’s acquiring viral infection (COVID-19) which is often featured by elevation of temperature (>100.3 F°), cough, severe fatigue, and a variety of symptoms mimicking the flu and pneumonias. This gradually may extend to a progressive and serious respiratory failure with associated ARDS-like status and severe pneumonias with residual scarring of the interstitial areas of the lung alveoli, resulting in acute life-threatening, and permanent compromised gas exchange. Those that survive with controlled ventilation (low tidal volumes), medical induced coma, and prone positioning, are often left with reduction in pulmonary function abilities. This paper reviews some pertinent knowledge and advances in understanding of the pulmonary injuries and long-term damage of the COVID-19 patients, and reports a study to ameliorate such damage with use of cSVF for those who successfully recover.
There now exists technology to perform sophisticated analytics (Functional Respiratory Imaging, FRI) developed by Fluidda (Belgium, EU) which provides great detail and information, including the ability to help triage the infected patients early to help assist in prediction of ventilation and ICU needs. In addition, author’s experience with use in Chronic Obstructive Pulmonary Disease (COPD) and Fibrotic Lung Diseases, the ability to evaluate effectiveness of use of cellular Stromal Vascular Fraction (cSVF) following intravascular deployment of isolated and concentrated cSVF. The hypothesis is that reduction of the widespread pulmonary inflammatory and immune responses which destroy much of the gas exchange abilities in the acute and residual damage which appears to create a long-term problem in the surviving patient population. Fluidda imaging analytics, coupled with standard pulmonary function studies, are effective at predictive studies which may prove of great help in anticipating which patient group is at most risk in the earlier infections to require ICU and potential ventilation needs.
Use of Stromal Vascular Fraction Cells (cSVF) are known to help mitigate damage from severe inflammatory disorders, provide immunomodulation, and promote repair and regenerative effects. The ease of access, simple ability to obtain significant numbers of viable cell elements, and the deployment via intravascular route has proven safe and efficacious in other forms of lung disease, including fibrotic lung disorders.
This paper reviews many of the current issues facing the severely infected Post-COVID-19 patient’s lung compromise, and a therapeutic option which clearly shows promise to reverse some residual damage of the lung and gas exchange functions.

Published: June 2020

La política televisada se ha convertido en un eje imprescindible en la planificación de las campañas electorales de cualquier partido político. La televisión es la principal fuente de información durante los procesos electorales y los espacios de politainment se han erigido en citas decisivas para los candidatos. Este artículo realiza un análisis diacrónico de la evolución de las audiencias de los debates televisados en España para comprobar si el paso del tiempo ha erosionado este formato. La muestra está formada por los diez debates electorales entre los aspirantes a presidir el Gobierno de España celebrados hasta abril de 2019. Asimismo, presta atención a la integración de otras pantallas en la difusión y visionado del debate electoral como Twitter. Los resultados de dicha investigación demuestran el interés de la audiencia española por este formato desde su primera emisión en 1993 hasta la actualidad, convirtiéndolos en verdaderos hitos televisivos. Además, los candidatos también han incrementado su presencia en la televisión a través de otros formatos de entretenimiento con el fin de mostrar otras facetas más humanas y emocionales al electorado. Esta reciente exposición mediática de los líderes políticos también ha sido seguida por la ciudadanía española.
Neurobiological and Relational Bases for Understanding Aggressiveness
Authors: Poljak Lukek Saša , Valenta Tanja 
Published: June 2020

Aggression is a deliberate, proactive or impulsive, defensive or active act, expressed through the use of physical power or psychological pressure. As such, it is a significant element of violent behaviour. According to developmental stages, aggression is expressed in various forms and is associated with the specific ways of regulating the feelings of shame and anger. We assume that excessive exposure and interrupted contact in development can lead to a specific regulation of the affects of shame and anger in a person who, because he feels threatened, can transform these feelings into aggressive behaviour. In addition, the dysregulated affects can lead to the dissociation of emotional experience, and thus to the inability to feel empathy, which allows for deliberate or proactive aggressiveness. Furthermore, the text presents the basic conclusions of research in the neurobiological understanding of aggression. The aggressive action is characterized by the specific functioning of the prefrontal cortex, the amygdala, and the sympathetic and parasympathetic nervous system. Abuse in childhood and relational trauma are presented as a starting point for the specific functioning of the brain and specific affect regulation, which can also be associated with aggressive behaviour in adulthood.
When the Family becomes the Most Dangerous Place: Relations, Roles and Dynamics within Incestuous Families
Authors: Repič Slavič Tanja 
Published: June 2020

The family is supposed to give the child a sense of security, belonging, acceptance and love.1 If, however, instead of these pleasant experiences, the most prevalent atmosphere is that of, abuse, trauma, violence, horror and fear, the child will not feel safe, accepted and loved. Even worse, later in life, he will unconsciously search for situations that will awaken in him, and re-create that primary atmosphere and underlying affects, because in his intrapsychic world, they equal belonging and familiarity. Clinical experience and research show that incest is one of the severest traumas caused to the human psyche and body. In the paper, we will first present the definition, prevalence and discuss factors such as the duration of the incest and the age of victims and perpetrators. Then, we will describe the relations, roles and dynamics within incestuous families, where the child finds himself with his own pain among people who should be trustworthy, who should give safety and a sense of being loved, but instead they abuse the child, violating all the boundaries, taking away one’s dignity and killing the soul.
