Published: April 2021

Background

Many solutions have been proposed in treating of forearm supination. Comparing with other supination function reconstructions, pronator teres rerouting is believed to be less effective. The aim of this study is to introduce a modified procedure, which avoids the shortness from previous attempts, and obtains good result.
Patients and Methods:

From 2015 to 2020, 11 patients have restored forearm supination by rerouting of the pronator teres weave sutured with allogeneic tendons. The average follow-up period was 17.5 months (12 to 24). The range of active supination at the final follow-up was recorded.
Results

Almost all patients acquired good supination range. The average active post-operative supination was 72.7° (60° to 80°) at the final follow-up. No complication was observed. All patients retained full range of pronation.
Conclusions

This study provides a modified supination function reconstruction with simple operating, fine results, low risks, and no affecting of pronation function. The use of allogeneic tendon makes up for the muscles with insufficient length, making it valuable to reconsider those rebuilding operations that were once considered unpromising by many.
An update on the H blood group system
Authors: Scharberg E.A. , Olsen C. , Bugert P.
Published: April 2021

This update of the H blood group system (Scharberg EA, Olsen C, Bugert P. The H blood group system. Immunohematology 2016;32:112–8) reports 11 new FUT1 null alleles: 8 causative for the H– phenotype (Bombay phenotype, Oh), 3 in para-Bombay cases, and 5 new FUT1 alleles causative for a weak H phenotype (para-Bombay, H+w). The H blood group system (International Society of Blood Transfusion system 18) consists of a single antigen (H) defined by a terminal fucose residue found on red blood cells (RBCs) and in secretions. The H antigen is synthesized on the RBC surface by the FUT1 gene product fucosyltransferase 1. On epithelial cells and in body fluids, the H antigen is synthesized by the FUT2 gene product fucosyltransferase 2.
Dilution is not the solution: acute hemolytic transfusion reaction after ABO-incompatible pooled platelet transfusion
Authors: Guarente J. , Harach M. , Gould J. , Karp J.K. , Peedin A.R.
Published: April 2021

The short shelf life of platelets makes providing ABO-compatible platelets a challenge, and many institutions issue ABO-incompatible platelets when compatible units are not available. It is presumed that ABO antibodies that exist in donor plasma are diluted when platelets from multiple donors are combined to make a pooled product for transfusion. We present a case of a hemolytic transfusion reaction in a 73-year-old man with myelodysplastic syndrome who received an ABO-incompatible pooled platelet unit. This case report demonstrates that the dilution theory is not always true for pooled platelet units, and any patient receiving ABO-incompatible platelet transfusions must be closely monitored for potential hemolytic transfusion reactions.
Addition of fresh serum to plasma to aid in enhancement of complement-dependent antibodies
Authors: Grey C.
Published: April 2021

EDTA anticoagulated plasma is the preferred testing specimen for the majority of blood bank testing today. EDTA in specimen collection tubes prevents the in vitro fixation of complement by chelating calcium. Antibodies in several blood group systems, such as Kidd, Kell, and Lewis, can bind complement and rarely may only be detectable when complement is present. Adding fresh ABO-compatible serum as a source of complement when one of these antibodies is suspected is a means to enhance their reactivity and identify and confirm their specificity.
An update on the Cartwright (Yt) blood group system
Authors: George M.R.
Published: April 2021

This update of the Cartwright blood group system (George MR. Cartwright blood group system review. Immunohematology 2012;28:49–54) reports the addition of three new antigens. From 1956 until 2017, the Cartwright (Yt) blood group system consisted of two antigens, Yta and Ytb. Yta is a high-prevalence antigen, and its antithetical antigen, Ytb, shows much lower prevalence. In 2017, YTEG was identified, and, in 2018, the International Society of Blood Transfusion added high-prevalence antigens YTLI and YTOT. Cartwright antigens result from point mutations in the acetylcholinesterase gene on chromosome 7q. Little is known about antibodies against YTEG, YTLI, and YTOT. Discovery of these new antigens required plasma inhibition studies and molecular analysis for further characterization. Based on experience with Yta and Ytb, Cartwright antibodies have rarely demonstrated clinical significance; nevertheless, cases of in vivo hemolysis have been reported, suggesting that clinical significance should be interpreted on a case-by-case basis.
The Xg blood group system: no longer forgotten

Published: April 2021

This update of the Xg blood group system (Johnson NC. XG: The forgotten blood group system. Immunohematology 2011;27:68–71) notes the identification of a cis-regulatory element of both XG and CD99 expression, remarkably by two independent groups during 2018, and confirmed by another in 2019. A single nucleotide change at the XG locus (rs311103) abolishes GATA1 binding and suppresses both XG and CD99. The last blood group system to resist elucidation of its genetic basis was thereby resolved. Soon afterwards, it was discovered that the rare anti-Xga response, mainly seen in men, is produced by individuals primarily carrying a large deletion in the X chromosome that truncates XG and leads to the Xgnull phenotype.
A prospective, observational study for optimization of antibody screening in pretransfusion compatibility testing
Authors: Pandey P. , Setya D. , Srivastava R. , Singh M.K.
Published: April 2021

Despite known use of antibody screening (AS), it has not been adopted uniformly across blood centers in India. Many centers in India are currently using a type and hold policy with subsequent antihuman globulin (AHG) crossmatch when blood units are requested. The main aim of this study was to assess the benefits of a type and screen (TS) policy in which blood grouping and AS are performed simultaneously during the first hospital visit. If the AS is negative, subsequent requests for blood units would require an immediate spin test (IST) crossmatch with release of blood units, followed by an AHG crossmatch. This prospective, observational study was conducted at a tertiary health care center between July 2014 and December 2018 and included only Indian patients. Blood grouping and AS were performed during the first hospital visit on a total of 22,888 patients; the majority of patients were from hemato-oncology and blood marrow transplant, hepatology and liver transplant, cardiothoracic vascular surgery, and medical intensive care units. Demographic parameters were evaluated for risk of alloimmunization, and a record of the same was maintained. Depending on the AS results, a further course of action was chosen. Clinically significant alloantibodies were detected in 145 patients, and autoantibodies were detected in 53 patients. Alloantibodies were mainly against Rh and Kell blood group antigens. A significantly higher proportion of patients in the AS+ group required blood transfusion when compared with the AS– group. In cases wherein the IST crossmatch was compatible but AHG crossmatch was not, follow-up did not demonstrate any clinical or laboratory evidence of hemolysis. AS is a safe, efficient, and beneficial tool for pretransfusion compatibility testing in both AS+ and AS– patients. With a TS policy, AHG crossmatch can be omitted in AS–e patients without compromising safety.
K antigens on neonatal red blood cells blocked by anti-K with titer of 32
Authors: Novoselac J. , Raos M. , Tomac G. , Lukić M. , Golubić Ćepulić B.
Published: April 2021

The blocking of red blood cell (RBC) antigens occurs when potent maternal antibodies bind to antigens on fetal or neonatal RBCs, causing them to be negative when typed with human IgM antisera. This phenomenon is rare; when it does occur, the antibody is usually of a high titer. This reported finding is typically due to anti-D, with rare reports describing false-negative K phenotyping due to blocking by maternal anti-K. We report a case of a potent anti-K with a titer of 32 that blocked K antigens on neonatal RBCs, causing them to phenotype as K–. The neonate also had clinically significant anemia (i.e., hemolytic disease of the newborn) due to the anti-K.
An update on the RAPH blood group system
Authors: Keller M.A.
Published: April 2021

This update of the RAPH blood group system (Hayes M. RAPH blood group system. Immunohematology 2014;30:6–10) reports no new alleles. The RAPH blood group system (International Society of Blood Transfusion system 25) consists of a single antigen (MER2) expressed on CD151, a member of the tetraspanin family of proteins. CD151 regulates interactions with laminin-binding integrins α3β1, α6β1, α6β4, and α7β1 and is expressed on red blood cells as well as many other tissues and cancer types. Lack of the RAPH protein is associated with nephropathy with pretibial epidermolysis bullosa and deafness.
Anti-Ata in a renal transplant candidate: a case report
Authors: Gao J. , Wise S. , Tinsley S.H. , Shikle J.F.
Published: April 2021

A patient with end-stage renal disease on chronic dialysis was admitted to the hospital for renal transplantation evaluation. Blood type and antibody detection tests were performed. The antibody detection test results were positive. Initial antibody identification studies indicated the presence of a panagglutinin. The patient’s autocontrol was negative. The antibody was subsequently identified by a reference laboratory as anti-Ata (Augustine), which is an extremely rare antibody due to the high prevalence of Ata in the general population. A monocyte monolayer assay (MMA) was performed to assess the clinical significance of the antibody in the event that blood was needed for transfusion, and At(a–) RBCs were not available. The MMA results predicted the antibody to be capable of causing hemolysis in vivo. A brief historical review of the incidence and clinical significance of this antibody is included in this case report.
Prevalence of DEL phenotype in D– blood donors in India
Authors: Chaudhary R. , Verma S. , Verma A.
Published: April 2021

Unlike weak D and partial D, DEL represents a weakened form of D that cannot be detected by conventional serology and requires use of an adsorption-elution method for its detection; therefore, DEL+ samples might be mistyped as D–. The study was undertaken to determine the prevalence of the DEL phenotype among D– blood donors from northern India. A total of 1003 D– blood donors were tested for weak D and DEL by the indirect antiglobulin test and an adsorption-elution method, respectively. Of the total 21,135 blood donors typed for D, 20,132 (95.3%) were D+ and 1003 (4.7%) gave a negative reaction for D. Of the total 1003 D– samples, 8 (0.8%) were weak D and only 2 (0.2%) were DEL+ by adsorption-elution testing. For samples that typed as D–, the majority of individuals (91.1%) were cde/cde (rr) followed by dCe/dce (r´r) in 4.8 percent, and dCe/dCe (r´r´) in 2.2 percent. Both DEL+ samples were also C+. We conclude that the prevalence of the DEL phenotype as detected by serology in D– north Indian blood donors is 0.2 percent, although it is as high as 2.8 percent in D–C+ individuals. There is an association of DEL with C, which can be used as a cost-effective marker for screening large numbers of D– blood donors for DEL.
Clinical impacts of DNA-based typing and provision of antigen-matched red blood cell units for chronically transfused patients with thalassemia
Authors: Watanaboonyongcharoen P. , Onspun S. , Rojnuckarin P.
Published: April 2021

Blood transfusion, the main therapy for patients with severe thalassemia, is challenged by alloantibodies that can lead to hemolytic transfusion reactions. The use of prophylactic antigen-matched units is recommended, but serologic typing, before the first transfusion, is rarely performed and is not reliable after chronic transfusion. Patient DNA-based typing is a promising strategy, but clinical outcome data are lacking. The aim of this study was to determine the benefits of antigen-matched transfusion guided by DNA-based typing in terms of new alloantibody formation and increases in mean pretransfusion hemoglobin (Hb) levels. We performed DNA-based typing on samples from 24 transfusion-dependent patients with thalassemia who had no serologic phenotyping performed before the first transfusion. These patients were then transfused with antigen-matched donor RBC units that were typed serologically. New alloantibody formation and mean pre-transfusion Hb levels were evaluated after implementing this extended common antigen-matching transfusion protocol. Sixty-three percent of the patients in this study were diagnosed as having beta-thalassemia Hb E. Alloantibodies were already present in 87.5 percent (21/24) of these patients, and most of these antibodies were multiple and/or unidentified. After the enrollment, there were 717 transfusion episodes comprising 1209 RBC units. The number of RBC units transfused to each patient ranged from 22 to 119 units. At the median duration of 25.5 months (range 10–34 months), no new alloantibodies were detected since the beginning of the protocol. Seventy-four transfusion episodes in six patients were cross-match-positive due to autoantibodies (patients 2, 4, 8, 9, and 14) or anti-Chido (patient 18) that had been identified before the study. There were no hemolytic transfusion reactions in this study. Five patients (patients 1, 2, 12, 15, and 20) showed increased mean pre-transfusion Hb levels (≥1 g/dL) and one patient (patient 16) had longer intervals between transfusions (compared with those before the protocol), suggesting longer RBC survival, although there was no statistical difference in the whole group. Our study highlights the benefits of DNA-based typing in chronically transfused patients with thalassemia who had no phenotyping data before the first transfusion. Patient DNA-based typing for antigen-matched transfusion is safe in thalassemia and allows us to obtain better-matched blood units for complicated patients.

The prevalence of blood group antigens and phenotypes varies significantly in Brazil. To ensure a proper rare blood supply, it is essential to establish a local and regional database of rare donors connected to the national registry. The objective of this study was to create a database of rare blood donors in the northern region of southern Brazil. From November 2011 to December 2018, red blood cell (RBC) phenotyping and genotyping were performed on common and high-prevalence antigens in donors and patients in southern Brazil. During this study period, 17 patients and 33 blood donors with rare phenotypes were identified. Six patients had already been alloimmunized to clinically significant antigens. Patients with the following phenotypes (i.e., negative for high-prevalence antigens) were found: Yt(a–), Jk(a–b–), Lu(a–b–), Oh (Bombay), Tc(a–), k–, and Fy(a–b–). Among the donors, Kp(a+b–), Fy(a–b–), Lu(a–b–), and k– phenotypes were identified. We also found four donors with the weak D type 18 phenotype. In conclusion, we observed that the prevalence of rare blood phenotypes in our region corresponds more to the prevalence found in the Caucasian population when compared with other regions in Brazil. Our results show the importance of continuous screening for rare donors in different regions of the country and the creation of a local database to support RBC transfusions in patients who need rare blood.

Published: April 2021

Purpose: Obstetric brachial plexus palsy (OBPP) causes various disorders in the musculoskeletal system. Studies investigating activity and participation in different types of injury are limited. This study aimed to determine the activity and participation levels of preschool children with different injury types of OBPP.Methods: The 112 children with OBPP, aged between 44 and 77 months, were included. The children were grouped according to the Narakas Classification System: Type 1 (n=7), Type 2 (n=91), Type 3 (n=2), and Type 4 (n=12). Both Type 3 and Type 4 represented a total brachial plexus injury. The Pediatric Outcome Data Collection Instrument (PODCI) was used to evaluate activity and participation.Results: Narakas Type 1 and Type 2 had similarly high scores in PODCI Global (p<0.001), and PODCI Upper Extremity (p<0.001), Pain/Comfort (p<0.001), and Sport (p<0.001) subscales as compared with Narakas Type 3/4. In the PODCI Happiness subscale, Narakas Type 1 had the highest score, followed by lower scores of Narakas Type 2 and Type 3/4 (p<0.001).Conclusion: Preschool children with total OBPP had lower levels of activity and participation, less use of their arm in daily living activities, and express a lower level of sport participation compared to those with upper plexus injuries (Narakas Type 1 and Type 2). As activity and participation problems persist or even got worse as the children grow, it is essential to evaluate both activity and participation, particularly in those with total plexus injuries, in preschool age and preferably earlier.

Snacking cessation: It’s time to challenge this eating behaviour
Authors: Krejany Catherine , Kanjo Epi , Jiwa Moyez
Published: April 2021

Our habits have changed over the generations. In particular, our eating behaviours continue to adapt and are intrinsically linked with changing social norms and myriad other influences leading us to consume more. In light of the obesity epidemic that threatens to be our greatest health challenge, the race is on to find new ways to modify or alter our food choices to those considered more “healthful”. Somewhere along the way snacking has become an acceptable eating pattern. We are uncomfortable foregoing these readily available and hedonistic food rewards. It may be time to change more than our food choice and question the need to snack at all.
Doctors have a limited role in managing obesity

Published: April 2021

Obesity management is one of the greatest challenges in medicine. While the obesity epidemic continues to grow, there is increasing pressure on doctors to do more to curb these trends. National bodies offer guidelines and action plans; however, these miss the mark within the constraints of modern practice. While urgent change is needed to combat the health challenges that global obesity raises, medical practice is generally ill-equipped to make an effective change for patients. Significant innovation is needed to be able to deliver strategies that will work in a healthcare context.

Redistribution of population and ionization of atomic Rydberg states due to multistep cascade transitions between states under the influence of radiation with continuous spectrum is considered. Consideration is carried up both by simulation of kinetic equations for state populations and with the use of a diffusion approximation based on the Fokker-Planck equation. On the example of sodium atom under the influence of radiation with rectangular spectrum a good agreement between the diffusion approximation and the kinetic equation simulation is shown. In the frame of the diffusion approximation some estimations are derived for the state populations, ionization rates and minimal spectral density of radiation necessary for significant ionization.

Методами теории функционала плотности проведены квантово-химические расчеты возбужденных состояний моно- и димезонитропроизводных октаэтилпорфирина (OEP) и их Zn-комплексов. Полученные данные свидетельствуют о том, что состояния с переносом заряда расположены существенно выше локально возбужденных состояний и не играют заметной роли в тушении флуоресценции данных соединений, как это предполагалось ранее. Показано, что для всех исследованных соединений в триплетном состоянии имеет место конформационная динамика, способствующая образованию структур с общей сопряженной системой связей между порфириновым макроциклом и нитрогруппой. Ее особенностью является малый активационный барьер (<200 сm-1) структурной перестройки и заметное уменьшение энергетического интервала Delta(T1-S0) между основным и нижним триплетным состояниями. Полученные данные указывают на то, что для H2-alpha-NO2-OEP, H2-alpha,γ-(NO2)2-OEP и Zn-alpha,γ-(NO2)2-OEP в триплетном состоянии в растворе толуола присутствуют конформации, для которых энергетический зазор Delta(T1-S0) заметно меньше 7800 сm-1. Это позволяет объяснить уменьшение квантового выхода интерконверсии для данных соединений в случае его оценки методом измерения интенсивности свечения синглетного кислорода. Неравенство единице суммы квантовых выходов интерконверсии и флуореценции для исследуемых соединений связано с конформационными превращениями в возбужденных состояниях, которые могут оказывать влияние на вероятность внутренней конверсии в синглетном состоянии и точность определения квантового выхода интерконверсии различными методами. Ключевые слова: квантово-химические расчеты, октаэтилпорфирин, возбужденные состояния, интерконверсия, флуореценция, квантовый выход.

For the 3Δ1 electronic state of the 179Hf 19F+ ion the energy shifts of the hyperfine structure sublevels of the ground rotational state due to the interaction of the electron electric dipole moment (eEDM) and magnetic quadrupole moment (MQM) of the 179Hf nucleus with internal electromagnetic field of the cation were calculated. A feature of eEDM and MKM search experiments on 179Hf 19F+ is the use of rotating external fields, which complicates the calculations and makes them more relevant. Experiments need to know energy levels structure in order to populate them, and knowledge of the g-factors of the levels will allow suppressing a number of systematic errors, related with incomplete control of the magnitude of the used magnetic field. Therefore, the corresponding calculations are also were held. Our calculations can be used to plan an experiment with a cation 179HfF+and interpretation of the obtained data.

The optical properties of unoxidized surfaces of polycrystalline Pr and Nd films in the spectral range 0.4 - 2.6 μm are studied. Optical constants were measured by Beattie ellipsometric method. Dispersion dependences of the optical conductivity σ, the reflectivity R, imaginary and real parts of the dielectric constant ε1 and ε2, and the function of characteristic electron energy losses Im (ε) -1 were calculated using the obtained optical constants. The paper presents the optical properties of both films and liquid metals studied earlier. The electronic characteristics of praseodymium and neodymium in solid thin-film and liquid states are calculated using the results of measurements in the infrared region of the spectrum using the two-band conductivity model.

Inhomogeneous Fredholm’s integral equations of the second kind are formulated, which describe the fields of TE and TM polarized waves in metallic films with allowance for the anomalous skin effect. The equations are solved numerically by the quadrature method. The electric fields in gold and aluminum films located on a silicon substrate and the angular dependences of the polarization angles of light reflected from the films are investigated. It is found that the solution of the inverse problem of multi-angle ellipsometry for metallic films using the standard model of the normal skin effect is characterized by instability of the reconstructed complex refractive index of the metal with a change in the thickness of the metallic film.
Электромагнитные волны в волноводе с периодически модулированным магнитодиэлектрическим заполнением

The propagation of electromagnetic waves in an ideal regular waveguide, filling of which is periodically modulated in space and time, is considered. It is assumed that the modulation depths are small and the modulation of the waveguide filling does not lead to the interaction between different waveguide modes. Wave equations are obtained for transverse-electric (TE) and transverse-magnetic (TM) fields in the waveguide with respect to the longitudinal components of the magnetic and electric vectors, respectively, are obtained. They represent second order partial differential equations with periodic coefficients. By changing the variables these equations are reduced to ordinary differential equations with periodic coefficients of the Mathieu-Hill type. Solutions of these equations are found in the first approximation with respect to small modulation depths in the region of “weak” interaction between the signal wave and the modulation wave (the Wulff-Bragg condition is not satisfied). The obtained results show that TE and TM fields in the waveguide in the above approximation are represented as the sum of three space-time harmonics (zero and plus and minus first) with complicated amplitudes and frequencies.

We study the process of vacuum birefringence in a strong electromagnetic field: a probe photon changes its polarization while traversing a counterpropagating laser beam. To describe this phenomenon, we calculate the polarization tensor in the field of a plane monochromatic wave to leading order with respect to its amplitude. The main goal of the study is to compare the results with the data obtained within the locally constant field approximation (LCFA). Here we identify the domain of the LCFA applicability in the case of a plane-wave external background. It is shown that the frequency of the probe photon and that of the external field are symmetrically involved in the relative uncertainty. The exact treatment of the spatiotemporal dependence beyond the LCFA becomes necessary at the energy scale 0.1-1 MeV.

Polycrystalline zinc films with the thickness of about 20, 40, 60, and 80 nm and mainly granular morphology comprising nearly spherical particles involving hexagonal crystals are obtained by magnetron sputtering on cover glass supports. Subsequently, the prepared layers were subjected to thermal oxidation in the air to obtain transparent zinc oxide layers. The synthesized films are studied by SEM and UV-vis spectroscopy. Based on the obtained spectra, optical properties of the layers are studied as a function of their thickness. The optical band gap Eg for the films with the thickness from 40 to 80 nm is estimated on the level about 3.28 eV similar to the reference value 3.3 eV for bulk zinc oxide, while for the thickness of 20 nm Eg slightly drops to about 3.24 eV. Keywords: zinc; zinc oxide; nanolayers; magnetron; oxidation; surface morphology; transparency; optical bandgap.

On the example of esters of carboxylic and dicarboxylic acids (ethyl acetate, diethyl oxalate, diethyl malonate, diethyl phthalate and dibutyl phthalate), as well as ketones, lactams and diketones (acetone, cyclohexanone, 4-ethylpropiophenone, acetylacetone and methylpyrrolidone) studies were carried out to generate electroluminescence (EL) in them of pure aluminum (Al) and preoxidized (Al2O3) in distilled water. The absence of EL in pure Al in ethers was revealed, and the regularities of luminescence generation in them for the oxidized metal were established. It was shown that in ketones and related compounds - lactams and diketones, the appearance of EL is possible for both states of the Al anode. In this case, the EL spectra have broad bands in the range 400 - 700 nm with maxima characteristic of the carboxyl and carbonyl groups of the electrolytes used, as well as the nanoporous structure of the formed Al2O3 and carbon-containing impurities captured by it during the growth. In some ethers and ketones, the effect of transformation of the initial structure of the oxide, as well as an increase in its thickness, was found. The absence of any changes in the chemical composition of electrolytes after anodic oxidation of Al in them or transformation of Al2O3 was established by UV, IR and NMR spectroscopy.

The results of processing the luminescence attenuation kinetics of an InP/InAsP/InP hybrid semiconductor nanostructure with deposited colloidal layers of CdSe/ZnS quantum dots (QD) under excitation at wavelengths of 532 and 633 nm and temperatures of 80 and 300 K. Such a nanostructure is characterized by a significant increase in the duration and intensity of the luminescence of the INASP nanostructure. The mechanism of increasing the luminescence duration is presumably associated with the interaction of the QD CdSe/ZnS-TORO colloid with the InP surface, which leads to the formation of new hybrid states in the band gap that are energetically close to the radiating state and are able to capture electrons, which in turn is compensated by the increasing role of the electron reverse transfer process, which leads to an increase in the duration of radiative recombination.

Актуальность. Согласно международным стандартам и подходами, адекватное кадровое обеспечение является обязательным условием и составляющей создания и успешного развития системы паллиативной и хосписной помощи (ПХП) в любой стране. Одной из основных задач современной профессиональной подготовки медицинских работников (М/Р), которые привлекаются к оказанию ПХП населению, является формирование у них осознания пациент-семья-ориентированной парадигмы, навыков мультидисциплинарной (МД)/командной, межведомственной и межсекторальной координации и сотрудничества. Также важно обеспечить тщательный отбор и соответствующую мотивацию кадров. Поскольку в основе современной системы ПХП лежит МД, межведомственный и межсекторальный подход к оказанию ПХП после соответствующей профессиональной подготовки могут привлекаться врачи любой специальности, младшие медицинские специалисты, а также психологи, социальные работники, юристы и священнослужители, волонтеры, представители местных общин и частных структур, а также сами паллиативные пациенты (ПП) и члены их семей или опекуны. Цель: научное обоснование профессиональной последипломной подготовки специалистов), которые привлекаются к оказанию ПХП населению. Материалы и методы.
