Inicialmente envío un especial y cálido saludo a todos los miembros de la Asociación Colombiana de Neumología y Cirugía de Tórax. Siento que mi vínculo con la Asociación Colombiana de Neumología y Cirugía de Tórax data desde cuando elegí la neumología como mi especialidad. El sentido de pertenencia al gremio germinó por voces de mi entonces mentor, el doctor Oswaldo Escobar Chamorro, miembro de número de nuestro gremio. Emergió una empatía por la Asociación mientras progresaba en mis estudios y conocimientos en el área médica, lo que luego, ya en el ejercicio profesional, se me transformó en espíritu de compromiso con la entidad. Y así, me fui involucrando con la asociación: inicialmente como miembro del Capítulo Costa Norte y posteriormente, como integrante de la Junta Directiva Regional, hasta llegar a ser su Presidenta en dos ocasiones.
Vistas la gran labor y los avances de la Asociación como comunidad científica, brotó en mí la ilusión de postularme para la Presidencia Nacional. El sueño se pudo consolidar gracias al apoyo inquebrantable de los miembros y, ahora, como Presidenta para el periodo 2021-2023, pretendo solidificar mis propuestas y mi visión a través de una labor que intento erigir en principios y metas comunes.

Published: June 2022

The data of the technological assessment for the suitability of new VNIISPK apple cultivars for jam are given: Aleksandr Boyko, Blagodat, Prazdnichnoye, Ivanovskoye and Patriot of winter maturation and Osipovskoye of summer maturation. Antonovka was taken as a standard cultivar. It is shown that according to organoleptic indicators, jam from all cultivars corresponded to GOST 31712-2012 and was at the standard level (4.4 points). However, according to the general tasting assessment, taking into account the appearance and taste, the jam from Patriot surpassed the jam from the standard cultivar; the jam from Blagodat was rated lower than the jam from Antonovka. A low variation of tasting ratings was noted (V = 2.8%), which indicates the stability of the technological properties of the cultivars on which the consumer quality of the finished jam depends. In accordance with the requirements of GOST 31712-2012 for the content of soluble solids in jam, the studied cultivars are recommended for the production of various types of jam: sterilized, "homemade", unsterilized using a preservative and without. The high content of soluble solids in the jam of Alexandr Boyko and Osipovskoye makes these cultivars very promising for this type of processing, since it allows packing jam into various types of containers, including large ones without preservative. In terms of the content of titrated acids in jam, almost all cultivars were inferior to Antonovka. Only Osipovskoye and Prasdnichnoe met the requirements of the standard for this indicator (at least 0.3%). According to the content of catechins in jam, none of the cultivars exceeded Antonovka (37.9 mg / 100g). Blagodat and Prasdnichnoe contained the lowest amount of catechins in jam (8.4 mg/100 g). As a result of technological study, it was found that the greatest suitability for jam was characterized by Aleksandr Boyko, Osipovskoye, Blagodat and Prasdnichnoe. Jam made from the fruits of these cultivars can be packed in containers of various capacities, including large ones and without the use of preservative.

Authors: Turki Waleed 
Published: June 2022

This research investigates manganese (Mn) extraction from Electric Arc Furnace Steel Slag (EAFS) by using the Liquid-liquid extraction (LLE) method. The chemical analysis was done on the slag using X-ray fluorescence, X-ray diffraction, and atomic absorption spectroscopy. This work consisted of two parts: the first was an extensive study of the effect of variables that can affect the leaching process rate for Mn element from slag (reaction time, nitric acid concentration, solid to liquid ratio, and stirring speed), and the second part evaluates the extraction of Mn element from leached solution. The results showed the possibility of leaching 83.5 % of Mn element from the slag at a temperature of 25°C, nitric acid concentration 2 M, time 90 min, S / L ratio 1/100, and stirring speed 700 rpm. 94.7% extraction of Mn was accomplished from nitric acid solutions by using Octyl Pyro Phosphoric Acid (OPPA) in kerosene at contact time for 12 min, 50%OPPA -kerosene, stirring speed 900 rpm, and organic to the aqueous phase (O/A) of 4/1. Kerosene was the most important diluting agent in extracting Mn, compared to benzene and toluene.

Published: June 2022

The proportional-integral-derivative (PID) is still the most common controller and stabilizer used in industry due to its simplicity and ease of implementation. However, in most of the real applications, the controlled system has parameters that slowly vary or are uncertain. Thus, PID gains must be adapted to cope with such changes.
In this research, an Adaptive Proportional-Integral-derivative controller (APID) is proposed to control the 2-DOF lower limb rehabilitation robot system. The parameters gains of the proposed controller are optimized using the Particle Swarm Optimization algorithm (PSO). The simulation results show no overshoot and zero steady-state error, but large settling time (ts=3.654 sec. for link1 and ts=2.844 sec. for link2) for linear path, and the actual path tracks the desired path with a large error for the nonlinear path. The results illustrate that the robot's performance is inefficient for linear and nonlinear paths when using the APID controller to control the lower limb rehabilitation robot. Therefore, the controller needs to modify for controlling the robot efficiently.
DIFFERENTIATED APPROACH TO PREVENTION AND TREATMENT OF ACUTE LEFT VENTRICULAR FAILURE IN PATIENTS WHO UNDERWENT CORONARY ARTERY BYPASS GRAFT SURGERY WITH CARDIOPULMONARY BYPASS
Authors: Cherniy V. I. , Kurylenko Y. V. 
Published: June 2022

Introduction. Coronary heart disease (CHD) is the accumulation of atherosclerotic plaques in the blood vessels that supply the heart with oxygen and nutrients. Coronary artery bypass grafting (CABG) is a strategy for myocardial revascularization that is indicated for patients with three or more coronary artery demage, high SYNTAX, diabetes, and left ventricular systolic dysfunction. Despite the tremendous development of equipment, surgical and anesthesia techniques, in the perioperative period, there are still complications. The most formidable complication after such an operation of CABG with cardiopulmonary bypass (CPB) is the development of acute left ventricular failure (ALVF).
The aim. To study the effectiveness of the principles of a differentiated approach to the prevention and correction of ALVF in patients who underwent surgery - CABG with CPB.
Materials and methods. 500 cardiac surgery patients with coronary heart disease were operated on at SIS “Research and Practical Center of Preventive and Clinical Medicine” SAD. In all the cases, coronary artery bypass grafting was performed using cardiopulmonary bypass. In order to verify the principles of a differentiated approach to the correction and prevention of ALVF, the study was divided into three stages. At the first stage, the problem of the metabolic component of ALVF correction was studied (60 patients). On the second - the problem of diagnosis and correction of hypophosphatemia (60 patients with preoperative hypophosphatemia). On the third - diagnostic properties of the innovative method "Phasagraphy" (80 patients).
Results. The introduction of a combination of levocarnitine and arginine, fructose-1,6-diphosphate - in case of hypophosphatemia, in the treatment of ALVF can reduce the recovery time of hemodynamics and reduce the total dose of inotropic drug (dobutamine) needed to achieve stabilization. The LF/HF indicator reliably reflects the ratio of sympathetic and parasympathetic parts of the autonomic nervous system, responds to disturbances and restoration of hemodynamics. The βT index of the phasagraphy method is related to clinical data on myocardial status.
Conclusions. To prevent the development of ALVF in patients with coronary heart disease requires a differentiated approach: perioperative diagnosis of hypophosphatemia and its correction. In the case of ALVF after CABG surgery in patients with coronary heart disease to stabilize hemodynamics, the use of inotropic support with dobutamine and metabolic support with a combination of levocarnitine and arginine. As monitoring of myocardial condition it is advisable to use LF/HF indicator of variation pulsometry and βT method of phasagraphy.

Published: June 2022

Summary. In the context of the reform of the medical industry in Ukraine, the issue of ensuring effective quality control of the provision of medical care and its proper organization in healthcare institutions, and primarily primary care providers (PCP), has become topical. Today in Ukraine, the control of the work of general practitioners-family doctors (audit) is a continuous process, the purpose of which is to improve the quality of medical care. The audit is characterized by a systematic approach, which makes it possible to identify problems, assess the achieved level of quality, plan, and implement changes aimed at improving the quality of medical care.
The audit of the work of doctors is divided into professional and administrative, as well as internal and external. The audit of the work of general practitioners - family doctors, as a rule, is a combination of all these types.
Internal quality control is carried out by the general/medical director of the PCP provider and the medical boards of the institution, and is divided into audit of the structure, process and result. In addition, there are forms of internal audit of the work of family doctors: self-control and self-assessment of quality, mutual assessment between colleagues, and assessment of the head of the PCP provider.
The external audit of the PCP supplier is represented by non-departmental, public and departmental control. The subjects of control are the authorized bodies outside the medical institution. External quality control of the provision of medical care is carried out by state authorities, clinical expert commissions of the Ministry of Health of Ukraine, public organizations. The financial audit is carried out by the National Health Service of Ukraine and the Department of Audit and Analytics of the Ministry of Health of Ukraine. Administrative audit is carried out by the Department of Audit and Analytics of the Ministry of Health of Ukraine.
Conclusions. In general, control over the activities of general practitioners - family doctors is an ongoing process and involves a systematic approach. Internal audits are conducted by members of the same profession, providing a unique opportunity to identify non-compliance with standards and change tactics before it leads to adverse consequences. External audit is carried out by state institutions. The balanced application of these two forms of audit allows to achieve a high quality of work of doctors. General practitioners - family doctors should strive for quality and regular internal audit as the main corrective factor in the implementation of quality care in family medicine.

Status gizi adalah keadaan tubuh sebagai akibat konsumsi makanan dan penggunaan zat-zat gizi. Makanan yang dikonsumsi dapat mempengaruhi timbulnya karies khususnya jenis makanan yang mengandung gula (glukosa, sukrosa, fruktosa) karena menyebabkan rendahnya asupan fluorida yang berperan penting untuk pencegahan karies gigi..Karies merupakan suatu penyakit pada jaringan keras gigi yaitu email, dentin dan sementum. Faktor utama penyebab karies adalah faktor host/ tuan rumah, agen/ mikroorganisme, substrak/ diet, dan waktu.
Tujun penelitian untuk mengetahui hubungan status gizi terhadap terjadinya karies gigi pada anak sekolah dasar.Metode penelitian ini merupakan penelitian systematicreview yangbertujuan menelaa hubungan status gizi terhadap terjadinya karies pada anak sekolah dasar ditinjau dari 10 jurnal penelitian. Artikel yang diteliti adalah mayoritas tahun 2020 (40%), desain penelitian dengan Analitik dengan design cross sectional (80%),sampling penelitian dengan Purposive Sampling (50%),Intrumen penelitian dengan observasi menggunakan format pemeriksaan Karies dan formulir penilaian antropometri status gizi sebanyak (80%).Analisis Statistik penelitian dengan menggunakan uji chi square dan uji korelasi person masing-masing (20%).
Hasil riview penelitian ini dapat di simpulkan bahwa kategori status gizi pada anak sekolah dasar mayoritas normal (70%) sedangkan karies gigi pada anak Sekolah mayoritas tinggi (80%). Hal ini di sebabkan karena kurangnya pemahaman anak-anak untuk menjaga kebersihan gigi dan mulut.
Hasil analisis yang di lakukan secara systematicreview terdapat hubungan yang signifikan antara status gizi terhadap terjadinya karies gigi. Hal tersebut dikarenakan semakin rendah indeks karies gigi pada responden, maka status gizinya akan semakin baik.

Microscopic examination of sputum using the Ziehl-Neelsen stain is the gold standard for TuberculosisÂ (TB), but it must be performed by experts with special skills. The purpose of this study is to accelerateÂ the determination of the microscopic results using the Ziehl-Neelsen stain. This research is an experimental method in which the test sample is treated and the sputum sample is controlled with up to 25 samples. The method development is very important to increase the sensitivity and specificity of the results of TB examination using microscopes. This observation shows that the indirect cytospin method has a narrower reading range on a circle with a diameter of only 7 mm, making it easier for a bacterial count compared to the traditional direct method with a size of 2 x 3 cm oval shape.Â The results of the microscopic examination were 21 positive specimens and 4 negative specimens. Mycobacterium tuberculosis with Ziehl-Neelsen staining gave the same results with a sensitivity and specificity of 100%.

Objects. Due to the polymer waste accumulation, the search for new directions for their utilization is urgent. Chemical recycling methods are of considerable interest, which allow one to obtain the original monomers or change the compositions of the copolymers. From the point of view of building a circular economy, a promising material is polyethylene terephthalate (PET), on the basis of which amorphous copolyesters can be obtained. The study aimed to analyze the simultaneous glycolysis and interchain exchange reactions of PET in the presence of the oligoethylene phthalate modifier with hydroxyl end groups and the study of isothermal crystallization of poly(ethylene phthalate-co-terephthalates) with different phthalate contents obtained in this way.Methods. Oligoethylene phthalate is synthesized by polycondensation. Poly(ethylene phthalateco-terephthalates) were obtained by the interaction of post-consumer PET with oligoethylene phthalate. The composition of the oligomer and copolymers was confirmed using Fourier-transform infrared spectroscopy, thermal characteristics and crystallization half-times were determined by differential scanning calorimetry.Results. In this work, the use of the post-consumer PET chemical recycling process, aimed at obtaining copolyesters under the influence of small modifier amounts was proposed. The process consisted in carrying out the combined interchain exchange and degradation with a complex oligoester different from PET. Poly(ethylene phthalate-co-terephthalate) copolymers were obtained via reaction of post-consumer poly(ethylene terephthalate) flakes and synthesized oligoethylene phthalate resin in the melt phase in the absence of catalyst. The effect of phthalate concentration in polymer on the isothermal crystallization of phthalate substituted poly(ethylene terephthalate) was estimated.Conclusions. The hypothesis about the possibility of using an oligoester modifier to obtain the PET-based copolymer at the high rate and without reducing the molecular weight to values characteristic of a monomer or oligomer has been confirmed. The process can be used to obtain random copolyesters based on post-consumer PET. The phthalate unit concentration increase is followed by decrease in the glass transition temperature, temperature and heat of fusion, and increase in crystallization half-times. Phthalate has a better ability to retard PET crystallization than 2-methyl-1,3-propanediol or furandicarboxylic acid, but is inferior to some of the other modifiers known.

Published: June 2022

O suicídio pode ser estudado sob muitos pontos de vista, uma vez que a decisão voluntária pela morte é algo complexo e de difícil explicação, por ser evidentemente multifatorial. A partir de um olhar interdisciplinar, dialogamos com autores/as da psicologia, psicanálise, psiquiatria, sociologia e filosofia a fim de compreender os resultados de uma pesquisa sobre a opinião de 316 estudantes universitários/as a respeito de uma série produzida pela Netflix, chamada “Os 13 porquês”. Os/as estudantes responderam a um questionário com questões abertas e fechadas sobre a série. As perguntas visavam colher informações sobre quais temporadas vistas, motivações para assistir a série, leitura do livro homônimo, conhecimento do pós-episódio, quais pessoas próximas assistiram à série e se houve diálogo sobre ela. E também investigar as opiniões dos sujeitos sobre: Você acha que a série ajuda a prevenir o suicídio? Você aprendeu algo com a série? O que achou da série? Cite aspectos positivos e negativos. A maioria dos/as participantes (59,8%) disseram que a série previne o suicídio parcialmente e 65,8% dos/as respondentes afirmaram terem aprendido algo com a série. Enfim, é possível concluir que a série abriu o debate sobre o suicídio e outros temas próximos como bullying, depressão e empatia. Porém, a forma como a série foi estruturada também foi considerada pelos/as pesquisados/as como um gatilho para o suicídio.
