Prevalence and Trends in Obesity Among Hospitalized Children
Authors: Kyler Kathryn E. , Bettenhausen Jessica L. , Hall Matthew , Hampl Sarah
Published: November 2019

OBJECTIVES:

As obesity rates rise in children, it is likely that the number of hospitalized children with obesity is also increasing. However, characterization of the inpatient population with obesity as a whole has not been reported. We aimed to examine trends in the annual prevalence of obesity in hospitalized children and to identify demographic and clinical characteristics associated with higher obesity prevalence in children who are hospitalized.

METHODS:

We completed a retrospective cohort analysis of children aged 2 to 19 years admitted to a single tertiary children’s hospital system for any reason in 2009–2016. Body mass index was calculated from documented height and weight. Children with obesity were defined by using age- and sex-specific body mass index percentile guidelines established by the Centers for Disease Control and Prevention. Annual obesity prevalence was calculated on the encounter level for service line and All Patients Refined Diagnosis-Related Groups (diagnosis groups). χ2 tests were used to determine statistical differences between groups, and the Cochran-Armitage test of trend was used to describe changes in obesity over time.

RESULTS:

Of 83 329 children who were hospitalized, 17.0% had obesity, increasing from 16.5% of hospitalizations in 2009–2010 to 17.3% in 2015–2016 (P = .002). Service lines with the highest obesity prevalence included orthopedics (22.1%), infectious disease (20.6%), and neuroscience (18.7%). Diagnosis groups with the highest obesity prevalence included cellulitis (22.5%), tonsil/adenoid procedures (22.0%), and some orthopedic procedures (28.7%).

CONCLUSIONS:

Some groups of children who were hospitalized experience higher obesity prevalence, including children hospitalized with orthopedic, infectious disease, and neurologic problems. In future research, investigators should target disproportionately affected groups by examining health outcomes, patient safety, and satisfaction issues.

BACKGROUND AND OBJECTIVES:

Workflow inefficiencies by medical teams caring for hospitalized patients may affect patient care and team experience. At our institution, complexity and clinical volume of the pediatric hospital medicine (HM) service have increased over time; however, efficient workflow expectations were lacking. We aimed to increase the percentage of HM teams meeting 3 efficiency criteria (70% nurses present for rounds, rounds completed by 11:30 am, and HM attending notes completed by 5 pm) from 28% to 80% within 1 year.

METHODS:

Improvement efforts targeted 5 HM teams at a large academic hospital. Our multidisciplinary team, including HM attending physicians, pediatric residents, and nurses, focused on several key drivers: shared expectations, enhanced physician and nursing buy-in and communication, streamlined rounding process, and data transparency. Interventions included (1) daily rounding expectations with prerounds huddle, (2) visible reminders, (3) complex care team scheduled rounds, (4) real-time nurse notification of rounds via electronic platform, (5) workflow redesign, (6) attending feedback and data transparency, and (7) resource attending implementation. Attending physicians entered efficiency data each day through a Research Electronic Data Capture survey. Annotated control charts were used to assess the impact of interventions over time.

RESULTS:

Through sequential interventions, the percentage of HM teams meeting all 3 efficiency criteria increased from 28% to 61%. Nursing presence on rounds improved, and rounds end time compliance remained high, whereas attending note completion time remained variable.

CONCLUSIONS:

Inpatient workflow for pediatric providers was improved by setting clear expectations and enhancing team communication; competing demands while on service contributed to difficulty in improving timely attending note completion.
Intraventricular Hemorrhage and White Matter Injury in Preclinical and Clinical Studies
Authors: Romantsik Olga , Bruschettini Matteo , Ley David
Published: November 2019

Germinal matrix–intraventricular hemorrhage (IVH) occurs in nearly half of infants born at less than 26 weeks’ gestation. Up to 50% of survivors with IVH develop cerebral palsy, cognitive deficits, behavioral disorders, posthemorrhagic ventricular dilatation, or a combination of these sequelae. After the initial bleeding and the primary brain injury, inflammation and secondary brain injury might lead to periventricular leukomalacia or diffuse white matter injury. Potential factors that are involved include microglia and astrocyte activation, degradation of blood components with release of “toxic” products, infiltration of the brain by systemic immune cells, death of neuronal and glial cells, and arrest of preoligodendrocyte maturation. In addition, impairment of the blood-brain barrier may play a major role in the pathophysiology. A wide range of animal models has been used to explore causes and mechanisms leading to IVH-induced brain injury. Preclinical studies have identified potential targets for enhancing brain repair. However, little has been elucidated about the effectiveness of potential interventions in clinical studies. A systematic review of available preclinical and clinical studies might help identify research gaps and which types of interventions may be prioritized. Future trials should report clinically robust and long-term outcomes after IVH.

Published: November 2019

Today, the European vector of our country’s development and the strategy of economic partnership with the EU pose certain challenges for our state. Signing the EU Association Agreement made an important impact on the changes in Ukrainian legislation concerning harmonization of laws and rules in economics. Providing the proper quality of agricultural products remains an important task. It requires improving the organizational and legal support in changing accents in legal regulation: giving manufacturers more freedom in economic issues instead of administering directly. The above-mentioned Agreement gave a good boost to create the State Service of Ukraine for Food Safety and Consumer Protection, which, in turn allowed merging three state organizations to start monitoring food safety and quality “from field to fork.” Especially important are the Requirements to the Development, Introduction, and Usage of Standing Procedures based on the HACCP system principles. Today, HACCP-based certification of standing procedures is not obligatory, unlike the presence of Prerequisite Programmes of HACCP, which is obligatory. A Prerequisite Programme must cover 13 processes: from planning the manufacturing, auxiliary, and staff facilities in order to avoid cross-contamination to marking finished products. A number of requirements must be met by each of these processes in particular. The authors of this article have analysed the legislation changes and the latest publications about a number of Ukrainian food enterprises that have introduced the HACCP principles. This analysis has allowed concluding that in these enterprises, this process has caused some changes in their manufacturing technologies and management systems. Groups of factors influencing the products’ quality have been outlined. The importance of the human element at various stages of quality formation and control has been emphasized. The existing systems of quality and safety management in food industries have been analysed in detail.

Published: November 2019

Aim.To study the associations of the frequency and values of parameters of the main risk factors (RF) of cardiovascular diseases (CVD) and the degree of transnosological polymorbidity (PM) in patients with nonalcoholic fatty liver disease (NAFLD).

Material and methods. The analysis of 3667 medical records (men, women) treated in the clinic of Research Institute of Experimental and Clinical Medicine (Novosibirsk) was carried out. Index of polymorbidity was evaluated by the number of nosological forms in accordance with the International Classification of Diseases, 10th revision (ICD-10). The following risk factors were assessed according to clinical and laboratory tests: arterial hypertension, dyslipidemia, hyperglycemia, obesity.

Results.Both among men and women with increasing index of PM there was identified growth of the parameters that determine the main RF: systolic BP, diastolic BP, obesity (both in men and women), atherogenicity index (in women), glucose concentration in the blood serum (in women). Frequency of AH occurrence in persons with a high degree of PM among men was 49%, and among women — 69% higher, compared with persons with a low degree of PM. Among men, there was an increase in the incidence of AH (by 9%) and obesity (by 9%) in individuals with a high degree of PM, compared with individuals with an average degree of PM. Among women, there was an increase in the incidence of AH (by 15%), obesity (by 9%), hyperglycemia (by 11%) in persons with a high degree of PM, compared with individuals with an average degree of PM.

Conclusion.There was established the role of risk factors for cardiovascular diseases, arterial hypertension mainly, in the development of polymorbidity in patients with NAFLD. The findings indicate the need for personified prevention and treatment of such patients with mandatory identification and correction of modifiable CVD RF.
Queer as a Bell: Music and the Psychotherapeutic Relationship
Authors: Harris Brian
Published: November 2019

Musical co-creation between the client and the therapist can be used as a means of skewing the dominant paradigms of the historically hierarchal psychotherapeutic relationship.  This process, known as queering, opens the possibility for new ways of being in therapy space that may support empowerment of both the client and the therapist. Music engagement contributes to an intersubjective dynamic where the therapist's material may enter the session space more vulnerably and authentically than through a purely verbal process.  When viewed critically through a queered perspective,  this intersubjectivity may allow for a decrease in the power differential traditionally associated with the client–therapist dyad. In this article, a queer theoretical perspective is used to examine the unique role music and creativity play in this therapeutic relationship. Current queer, linguistic, and creative arts therapy theory are examined to support the hypothesis.
Queering the Curriculum: Why Music Therapy and Other Creative Arts Therapy Trainings Need Queer Theory
Authors: Baines Sue , Pereira Jude , Edwards Jane , Hatch Jennyfer
Published: November 2019

Music therapy academic faculty responsible for teaching the next generation of healthcare practitioners have a responsibility to ensure that the learning environment is one in which the principles of equity and inclusion are upheld and practiced. Without queer perspectives included in the curriculum, promotion and continuation of heteronormative and cisnormative attitudes and beliefs increase. As media, culture, and society reflect increasing awareness of and open-mindedness toward queerness, so does the opportunity for reflection and questioning regarding binary identities and exploration of the need to shift to fluid, spectrum identity categories. This questioning begins with perceiving that contemporary social identities are formed from a limited conception of a normative binary that recognizes only heteronormative and cisnormative sexual orientation and gender identities, which can be extended to other inadequate and unhelpful binaries, for example dis/abled and racial binaries that entrench prejudice. Reviewing current teaching environments and methods allows for consideration of how social constructions limit the capacity of educators to fully include attention to, and critique of, all thoughtless binaries – whether gay/straight, female/male, old/young etc. In this paper we reflect on and reveal predominant heteronormative and cisnormative values in music therapy education, advancing ways to make classroom and practicum settings a safe and exploring space, with the potential to positively impact all students and their current and future clients.

Calculation of heat transfer in nanoscale heterostructures
Authors: Abgarian K. K. , Kolbin I. S.
Published: November 2019

Abstract. The article discusses the calculation of the temperature regime in nanoscale AlAs/GaAs binary heterostructures. When modeling heat transfer in nanocomposites, it is important to take into account that heat dissipation in multilayer structures with layer sizes of the order of the mean free path of energy carriers (phonons and electrons) occurs not at the lattice, but at the layer boundaries (interfaces). In this regard, the use of classical numerical models based on the Fourier law is limited, because it gives significant errors. To obtain more accurate results, we used a model in which the heat distribution was assumed to be constant inside the layer, while the temperature was stepwise changed at the interfaces of the layers. A hybrid approach was used for the calculation: a finite−difference method with an implicit scheme for time approximation and a mesh−free model based on a set of radial basis functions for spatial approximation. The calculation of the parameters of the bases was carried out through the solution of the systems of linear algebraic equations. In this case, only weights of neuroelements were selected, and the centers and «widths» were fixed. As an approximator, a set of frequently used basic functions was considered. To increase the speed of calculations, the algorithm was parallelized. Calculation times were measured to estimate the performance gains using the parallel implementation of the method.
Influence of technological factors on the characteristics of ohmic contacts of powerful AlGaN/GaN/SiC HEMT

Published: November 2019

Abstract. In this paper are considers the effect of the microrelief, dislocation structure and other defects of the epitaxial layers of the source and drain regions of the nitride HEMT transistors on the parameters of the formed ohmic contacts. The studies were carried out directly on high−power microwave transistors made of GaN/AlGaN/GaN/SiC heterostructures. Ohmic burning contacts were formed using the compositions Ti—Al—Mo—Au and Ti—Al—Ni—Au. To estimation the structural features of the contact areas, the surface microrelief at the interface of the burned contact/AlGaN and the defects formed on its surface was studied. It is shown that the resistance of the source and drain regions is largely determined by the surface microstructure at the boundary. Experimentally shown is the formation of a conducting layer in AlGaN under the ohmic contacts. The possibility of the formation of a new type of structural defects with a high aspect ratio in the contact and active areas of the devices during the formation of ohmic burned contacts is demonstrated. It is shown that the appearance of high densities of such defects leads to an increase of the device leakage currents.

Authors: Zaitseva Yulia N. , Novikova Svetlana A. , Parfenov Vladimir A.
Published: November 2019

Mesostructured carbon material CMK-3 for electrodes of electrochemical capacitors was obtained by the method of template synthesis. In order to increase the capacitance characteristics, impregnation of metal ions (Co, Ni, and Cu) into the structure of mesoporous carbon CMK-3 was carried out. The structure of the obtained materials was studied by X-ray diffraction and gas adsorption. The study by TEM showed that highly dispersed, nanosized particles are metal oxides Co, Ni and Cu with the size of 30-50 nm. The particles are uniformly distributed inside the carbon material. Electrochemical characteristics were studied in aqueous electrolytes (1M KCl and 1M KOH). It has been established that the impregnation of metal ions increases in the specific capacity of the mesoporous carbon material by about 30 % (from 110 to 156 F/g) in KOH

It was first synthesized by 1-isopropyl-3-α-naphthyl- 5-methoxymethyl-4-aminopyrazole which was then sulfonylated by p-acetamidobenzenesulfonyl chloride and p-toluenesulfonic chloride. As a result previously unknown sulfonylated derivatives of N-alkylated aminopyrazoles were obtained. The composition and structure are confirmed by modern methods of analysis such as IR, 1H NMR spectroscopy and mass spectrometry
Ángel Cuervo: curiosidades de la vida americana en París o de la defensa de la identidad latinoamericana
Authors: Ramírez Jaramillo John Fredy
Published: November 2019

Este artículo estudia la forma en que Ángel Cuervo, intelectual colombiano del siglo xix, argumenta en su libro Curiosidades de la vida americana en París la defensa de la identidad latinoamericana. Se comprobará que dicha tutela, además de corresponderse con una crítica a los europeos que subvaloran a las naciones y habitantes de la América Meridional sin establecer matizaciones de ningún tipo, incorpora un llamado de atención a los ricos inmigrantes latinoamericanos que, renegando de su propia cultura e idiosincrasia, buscan imitar el estilo de vida de la aristocracia europea.
El “Ciudadano” amazónico en el discurso político oficial
Authors: Lovón Cueva Marco Antonio
Published: November 2019

La explotación de la Amazonía se sostiene bajo los discursos de la civilización y colonización. Para ello, el aparato ideológico racista construye una imagen negativa de los aborígenes amazónicos. En este artículo, se estudia el discurso del expresidente Alan García como ejemplo de los discursos políticos antiamazónicos. Se demuestra que su discurso está basado en dos creencias discriminatorias: 1) Entre dos clases de ciudadanos, los amazónicos son ciudadanos de segunda clase y 2) El crecimiento económico es obstaculizado por grupos primitivos como los amazónicos. Para ello, desde el análisis crítico del discurso, se examinan las estrategias léxicas y discursivas presentes en un texto del citado mandatario. Finalmente, se concluye que el discurso de Alan García es una manifestación de una práctica social que reproduce discriminación en el país.

Mediante un estudio de caso se indagó por el lugar de la autoridad en la formación ciudadana de un grupo de estudiantes del municipio de El Carmen del Darién, en el Departamento del Chocó. Este se encuentra asociado, por un lado, a las formalidades del Gobierno Escolar en el marco de las competencias ciudadanas dentro de la institución educativa y, por el otro, fuera de ella, a la violencia ejercida por grupos armados al margen de la ley que se disputan el control del territorio desde hace varios años, dando lugar a la violencia como expresión de la autoridad.
Asimetrías y diversidad en las relaciones naturaleza-cultura: una reflexión en torno a la modernidad occidental
Authors: Piñeiro Aguiar Eleder
Published: November 2019

En este texto de carácter exploratorio desarrollamos una genealogía acerca de la visión que diferentes autores y teorías occidentales han desarrollado en torno a la idea de naturaleza y su relación con el progreso, desde la fiolosofía clásica hasta la modernidad eurocéntrica. A continuación, contraponemos lo que consideramos  un imaginario universal en torno a las relaciones naturaleza-cultura con otras investigaciones procedentes del Sur global y en particular de diversas teorizaciones indigenistas, latinoamericanas y decoloniales. Para todo ello se ha desarrollado una revisión documental en torno a textos “clásicos” y actuales, concluyendo que el individualismo y desarrollismo emanados de la tradición occidental encuentran fracturas, resistencias y puntos de fuga planteados desde perspectivas académicas y activistas que articulan un discurso contrario al extractivismo epistémico y materialista eurocéntricos.

The study objectiveis to assess the capabilities of ultrasonography in the diagnosis of oropharyngeal squamous cell carcinomas and in the evaluation of treatment efficacy (changes in tumor volume).

Materials and methods.This study included 98 patients (27 (27.5 %) females and 71 (72.5 %) males aged between 20 and 78 years with oropharyngeal tumors; of them, 12 (12.2 %) patients had recurrent tumors. Sixty-seven (68.4 %) participants had their tumors located in the tonsils; 31 (31.6 %) patients had tumors of the root of the tongue; 47 (48.0 %) patients presented with tumors invading adjacent tissues; 57 (58.2 %) patients had their lymph nodes involved. Thirty-two patients were operated at the first stage of treatment, whereas 66 (67.3 %) individuals received induction chemotherapy followed by sequential chemoradiotherapy. Treatment efficacy was evaluated 2 weeks following the completion of the second course of induction chemotherapy. We assessed tumor volume, its structure, type and intensity of vascularization, and the number and size of lymph nodes affected by metastasis. Ultrasonography findings were compared with the results of fibroscopy, X-ray computed tomography (CT) and magnetic resonance imaging (MRI) performed 2 weeks following the completion of the second course of induction chemotherapy (no later than 7–10 days).

Results.The disagreement between histology and ultrasonography findings reflecting tumor volume (of either newly diagnosed or recurrent tumor) was statistically insignificant. The results of X-ray CT were more likely to be in agreement with histology than the ultrasonography results (85.0 % vs 70.0 %); however, this difference was not statistically significant. Data of X-ray CT and ultrasonography on the tumor volume demonstrated no significant difference between them. MRI and ultrasonography findings on the tumor volume were consistent in 50 % of cases. We identified the most common changes in the structure of the oropharyngeal tumors typical of positive and negative dynamics after 2 courses of induction chemotherapy. Patients with positive dynamics demonstrated a significant decrease in tumor volume detected by all diagnostic methods used (ultrasonography, X-ray CT, and MRI). There was a significant negative correlation between the efficacy of treatment assessed by ultrasonography and the grade of therapeutic pathomorphosis assessed by histology (r = –0.69; р = 0.0014).

Conclusion.The accuracy of ultrasonography for the estimation of oropharyngeal tumor volume and its spread is comparable with that of X-ray CT and MRI. The disagreement between these methods was statistically insignificant. Ultrasonography is a more sensitive method for the evaluation of patient response to treatment than clinical data.

Medullary thyroid cancer (MTC) is a rare disorder that accounts for approximately 1.7 % of all thyroid malignancies. MTC is usually detected at early stages; however, approximately 10–15 % of patients are diagnosed with locally advanced MTC and distant metastases. Treatment of such patients is challenging due to biological characteristics of the disease and very few effective treatment approaches available. The investigation of mechanisms of carcinogenesis, as well as advances in pharmacology, allowed the development of a new group of targeted drugs, namely tyrosine kinases, which efficacy against progressive unresectable locally advanced or metastatic MTC has been demonstrated in multiple clinical trials. Vandetanib has been registered for MTC treatment in the Russian Federation. MTC is very rare, thus, each case of vandetanib use for its treatment is particularly interesting. Moreover, since the approval of this drug in 2011 by the U. S. Food and Drug Administration (FDA), new data on the clinical use of vandetanib have been accumulated. Importantly, clinical trials are usually well designed and conducted in near-ideal conditions, whereas the real conditions can be different and patients may have individual characteristics. Therefore, the aim of this study was to update the information on the efficacy and safety of vandetanib by retrospective analysis of available publications and to report a case of MTC treated with vandetanib.

The objective of the work is to demonstrate the signs of mucoepidermoid carcinoma of the minor salivary glands in pediatric patients on a clinical example.

Clinical case. In August 2017, a girl of 9 years old appeared in the area of the right half of the hard palate. The dentist at the place of residence diagnosed an abscess in the area of the hard palate, performed the lancing and drainage of the “abscess”, prescribed antibiotic therapy. After 3.5 months (in December 2017), hyperemia and an increase in the volume of the mucous membrane reappeared in the same zone. Reapplied to the dentist. The girl was sent to the Oral and Maxillofacial Surgery Department, where the hard palate formation was removed on 23.01.2018; according to histological examination a highly differentiated tumor of the hard palate was diagnosed. The girl was sent for a consultation to the N. N. Blokhin National Medical Research Center of Oncology, where histological preparations were reviewed: a fragment of the mucous membrane of the hard palate covered with squamous epithelium, with the growth of low-grade mucoepidermoid cancer (from the minor salivary glands of the hard palate). A biopsy of the postoperative scar 3 mm long and of the formation of a hard palate 1 mm in diameter was performed; during histological examination of the biopsy material tumor cells were not detected (the material was represented by fibrous tissue). Despite the biopsy results, taking into account the medical history, the results of a review of histological preparations, the rarity and high aggressiveness of the tumor, poor prognosis for relapse, lack of data for regional and distant metastases, at the concilium it was accepted the decision to conduct repeated surgery. In the Surgical Department No. 1 of the Research Institute of Pediatric Oncology and Hematology, N. N. Blokhin National Medical Research Center of Oncology on 13.03.2018 a resection of the hard palate was performed with plastic surgery of the defect with a mixed skin-muscle flap on the vascular pedicle.

Conclusion. Mucoepidermoid cancer of the minor salivary glands of the hard palate in children and adolescents can be manifested by the presence of a slowly growing, painless, pale blue tumor. For a correct clinical and morphological diagnosis, a biopsy of the tumor is necessary, further the removal of the tumor is recommended with resection of the hard palate, in view of the high risk of tumor spreading in the thickness of the bone.

The objective is to demonstrate possibilities of a harpoon biopsy under ultrasound guidance for malignant neoplasms early detection using a clinical example.

Clinical case. A 65-year-old patient with morphologically verified laryngeal cancer (stage II, T2N0M0) underwent radiation therapy, which resulted in a complete tumor resorption. Subsequent ultrasound detected a neoplasm in the projection of the folding section. Percutaneous harpoon biopsy was performed under ultrasound guidance because standard clinical and instrumental studies were unable to confirm the diagnosis. Histological study of the biopsy material confirmed the “relapse of larynx squamous cell carcinoma”.

Conclusion. A transdermal harpoon biopsy under ultrasound guidance followed by morphological biopsy study makes it possible to diagnose the disease and determine therapeutic approach as soon as possible.
ACADEMICIAN ARKADIY ZHUKOVSKY: SCIENTIFIC CONTRIBUTION TO POLITICAL GEOGRAPHY
Authors: VINTONIAK Alla
Published: November 2019

Arkadiy Zhukovsky made a weighty contribution to the theory, methodology and practice of political geography. Study of the territorial organization and geographical patterns of formation and development of the political sphere of public life, reflecting the essence of political geography as a science, underlie many of his researches. The purpose of this article is to reveal and clarify the main works of the scientist, which characterize important political and geographical events. The work “All-Russian Constituent Assembly” by A. Zhukovsky is an interesting exploration related to political geography. It is valuable because it highlights the role of the highest electoral institution of the former Russian Empire through the prism of all-Ukrainian interests. World political map, its stages of formation and existing state constitute another key area of political-geographical research, constantly staying in the focus of A. Zhukovsky. This is evidenced by his “World Wars” exploration. Doubtless, Ukraine was in the center of his research. The next, equally important direction of political geography, contributed by A. Zhukovsky, are peculiarities of national territory formation, the place and significance of national capitals, and the issues of administrative-territorial division of the countries. Finally, the territorial organization of political activity, being an instrument of individuals or communities to implement their political interests, was an aspect that A. Zhukovsky also made a lot of effort to investigate.

Published: November 2019

This research was
conducted at experimental site (41°10.668′ N latitude, 40°54.018′E longitude),
with 65 m elevetion in Turkey. In the study, 8 different genotypes of Digitalis ferrruginea subsp. ferruginea, selected in the previous
years with high performance, were used. These genotypes, grown in 2016-2017, were
compared in terms of plant height, panicle length, number of capsules per
panicle, capsule length, seeds yield per plant and 1000 seeds weight, and a
modeling was developed to estimate seed yield per plant. The mean values
obtained for the investigated traits were 95.21–130.43 cm for plant height,
46.29–72.57 cm for panicle length (PL), 9.63–11.14 mm for capsule length,
99.29–146.57 units for the number of capsules per panicle, 2.00–5.26 g/plant
for seed yield per plant (SYP) and 0.34–0.49 g for 1000 seeds weight (TSW).
However, in terms of the traits examined, each genotype showed a wide variation
within itself. Multiple regression analysis was performed for the
yield-prediction model relation to the seed yield per plant using the values
obtained under the present conditions. As a result of the regression analysis,
an equation of SYP=(-2.54)+ (0.11xPL)-(2.18xTSW) was obtained.
