PURPOSE:

Consent processes are critical for clinical care and research and may benefit from incorporating digital strategies. We compared an electronic informed consent (eIC) option to paper consent across four outcomes: (1) technology burden, (2) protocol comprehension, (3) participant agency (ability to self-advocate), and (4) completion of required document fields.

METHODS:

We assessed participant experience with eIC processes compared with traditional paper-based consenting using surveys and compared completeness of required fields, over 3 years (2019-2021). Participants who consented to a clinical trial at a large academic cancer center via paper or eIC were invited to either pre-COVID-19 pandemic survey 1 (technology burden) or intrapandemic survey 2 (comprehension and agency). Consent document completeness was assessed via electronic health records.

RESULTS:

On survey 1, 83% of participants (n = 777) indicated eIC was easy or very easy to use; discomfort with technology overall was not correlated with discomfort using eIC. For survey 2, eIC (n = 262) and paper consenters (n = 193) had similar comprehension scores. All participants responded favorably to at least five of six agency statements; however, eIC generated a higher proportion of positive free-text comments ( P < .05), with themes such as thoroughness of the discussion and consenter professionalism. eIC use yielded no completeness errors across 235 consents versus 6.4% for paper ( P < .001).

CONCLUSION:

Our findings suggest that eIC when compared with paper (1) did not increase technology burden, (2) supported comparable comprehension, (3) upheld key elements of participant agency, and (4) increased completion of mandatory consent fields. The results support a broader call for organizations to offer eIC for clinical research discussions to enhance the overall participant experience and increase the completeness of the consent process.
Postcesarean Analgesia With Epidural Morphine After Epidural 2-Chloroprocaine: A Randomized Noninferiority Trial
Authors: Lee Linden O. , Ramirez-Chapman Ana Lisa , White Danielle L. , Zhang Xu , Lu Monica , Suresh Maya S.
Published: December 2022

BACKGROUND:

Previous studies have suggested that administration of epidural 3% 2-chloroprocaine (CP) before epidural morphine results in decreased analgesic efficacy of epidural morphine. We sought to determine whether these observations were a result of antagonism or a window period between the conclusion of surgical anesthesia for cesarean delivery and the peak onset time of epidural morphine, and whether a method to preserve the analgesic efficacy of epidural morphine exists.

METHODS:

Term parturients scheduled for nonemergent, unscheduled cesarean delivery with preexisting labor epidural catheters were recruited for this exploratory, randomized, single-blinded, noninferiority trial. Subjects were randomized to initial dosing to a T4 dermatome surgical anesthetic level with either 3% CP or 2% lidocaine with 1:200,000 epinephrine and sodium bicarbonate (LEB). Subsequent redosing for both groups was performed with LEB at regular intervals. Epidural morphine 3 mg was administered to both groups after delivery. Assessing the difference between the 2 groups in total opioid use for the first 24 hours after epidural morphine administration was the primary objective. The noninferiority margin of 10 oral milligram morphine equivalents was prespecified based on previous noninferiority studies. Secondary end points included time from epidural morphine administration to first rescue opioid request, numerical pain scores, nausea/vomiting, and pruritus.

RESULTS:

Data were analyzed for 40 parturients, 20 in each group. The median 24-hour opioid consumption for the CP group was 0 (Q1 = 0 and Q3 = 15.6) oral milligram morphine equivalents compared to 15 (6.3–22.5) for the LEB group. The median difference was −7.5, with a 95% confidence interval −15 to 0. Noninferiority was concluded, as the confidence interval was less than the predetermined noninferiority margin of 10 oral milligram morphine equivalents. There was no treatment effect on time to first opioid request and no statistically significant differences in pain scores or nausea, vomiting, or pruritus at all time points (4, 8, 12, and 24 hours after epidural morphine administration).

CONCLUSION:

While designed as an exploratory study, initial epidural dosing with 3% CP and beginning subsequent redosing with LEB within 30 minutes of the initial CP bolus provided noninferior postcesarean analgesia with epidural morphine compared to initial epidural dosing and redosing with LEB. Previous observations of decreased analgesic efficacy of epidural morphine after epidural CP were likely due to a window period that may be mitigated by redosing with lidocaine; however, larger studies are necessary to confirm these findings.

After the first half of the fourth century, the Christian doctrine appeared to be the indisputable, sovereign cult, in the religious conflicts that took place in the vast acreage of Late Roman Empire. Not only it prevailed upon the various pagan cults of the empire, but it also ended up as the imperial cult. Earlier this period, the ethnonym “Hellen” adopted a novice, “religious-based” meaning, designating “pagans”, which would prevail among others in the following centuries.Emperor Julian’s reign (361-363) comprised a brief disruption of the inevitable domination of Christianity. In the present paper, we study the functions of the appellative “Galilean” and the ethnonym “Hellen” in the julianic corpus, in order to contribute to the apprehension of the julianic philosophical and religious thought, as well as to illuminate undiscernible shades in the functions of the terms under study.

The present study examines the evidence for the basilikon sekreton (tribunal)in Thessaloniki. It is concluded that, contrary to what has been assumed,there was no basilikon sekreton in the city during the first half of the 14thcentury, but only the euages sekreton of Yolanda-Irene Montferrat (1304),the second wife of Andronikos II Palaiologos. The basilikon sekreton inThessaloniki appeared only after the establishment of the katholikoi kritaiof Thessaloniki, as in the case of the katholikoi kritai of Rhomaioi whosetribunal was also named basilikon sekreton. The first references to thebasilikon sekreton in Thessaloniki are found in documents dating to 1374 and 1375.

Ο χώρος της εκπαίδευσης στην Ελλάδα διαχρονικά αποτελεί υψηλή προτεραιότητα εφαρμογής κυβερνητικών πολιτικών, συχνά αποσπασματικού χαρακτήρα μεταρρυθμίσεις δίχως ευρύτερες σύστοιχες παρεμβάσεις στο συγκείμενο πλαίσιο. Συχνά, επίσης, η εκπαιδευτική μεταρρύθμιση στοιχειοθετείται σε μια κοινότυπη διαπίστωση εκπαιδευτικής κρίσης, χρονιζόντων παθογενειών και αναχρονιστικών πολιτικών και ιδεοληψιών που αναστέλλουν την προοπτική ανάπτυξης της χώρας, ανάγοντας την κοινωνική και πολιτική συναίνεση εφαρμογής σε «εθνικό καθήκον» για το συμφέρον της κοινωνίας και των πολιτών σ’ ένα νοηματοδοτημένο συμπεριληπτικό πλαίσιο. Στη διατριβή προσεγγίζουμε τον πολιτικό λόγο ως μορφή κοινωνικού νοήματος και πρακτικής για την αναπαράσταση και συγκρότηση μιας νέας εκπαιδευτικής πραγματικότητας που σταδιακά δομείται, συγκρουσιακά κατά τη μεταπολίτευση, και κορυφώνεται με άτυπες συναινέσεις στο Ν.2525/97, ορίζοντας τη μετάβαση σ’ ένα νέο πλαίσιο κατάθεσης εθνικών εκπαιδευτικών πολιτικών υπό την καθοριστική επιρροή των διεθνών εξελίξεων.

Στην παρούσα διατριβή προσδιορίζονται οι ιδιαιτερότητες της ρωμαϊκής τραγωδίας ανά περίοδο και οι σύγχρονες προσεγγίσεις της σενέκειας τραγωδίας. Αναζητείται ο ρόλος της Θείας Πρόνοιας και της Μοίρας συνολικά στον Στωικισμό ώστε να εντοπιστούν τυχόν αντιστοιχίες με το τραγικό έργο του Σενέκα, αλλά και η φύση αυτών των δυνάμεων στα φιλοσοφικά του έργα. Αποφεύγεται να δημιουργηθεί συσχετισμός με τα φιλοσοφικά του έργα, παρά μόνο αναφέρονται τυχόν πιθανές απηχήσεις ή ομοιότητες, καθώς δεν είναι βέβαιη η χρονολόγηση του τραγικού έργου του Ρωμαίου ποιητή και φιλοσόφου. Οι οκτώ γνήσιες τραγωδίες του προσεγγίζονται ξεχωριστά, ανά ενότητα. Στο τέλος της κάθε τραγωδίας απαντούν ξεχωριστά συμπεράσματα για την καθεμία αναφορικά. Στο τέλος της διατριβής απαντούν συνολικά συμπεράσματα για τις τραγωδίες ξεχωριστά που περιλαμβάνουν τα πιο κύρια σημεία για τον προσδιορισμό του ρόλου της Θείας Πρόνοιας και της Μοίρας στην εκάστοτε τραγωδία αλλά και γενικότερες παρατηρήσεις για τη λειτουργία αυτών των δυνάμεων στο τραγικό έργο του Σενέκα. Στις τελευταίες σελίδες επισημαίνονται οι βασικές ερευνητικές θέσεις και τα ουσιαστικά πορίσματα της παρούσας έρευνας συνοπτικά. Διαπιστώθηκε ότι πολύ συχνά οι υπερκόσμιες δυνάμεις της Θείας Πρόνοιας και της Μοίρας στις τραγωδίες του Σενέκα συνυφαίνουν τη δράση τους και με άλλες όπως η Φύση, η κληρονομική κατάρα, η Αναγκαιότητα, το Πεπρωμένο, η Τύχη, συνεπώς μοιραία αποτελεί αντικείμενο της έρευνας η αποσαφήνιση και του δικού τους τρόπου λειτουργίας στις τραγωδίες, αλλά κυρίως του τρόπου αλληλεπίδρασης με τη Μοίρα και τη Θεία Πρόνοια ή ανταγωνισμού που μπορεί να αναπτύσσουν. Η θεωρία της κοσμικής συμπάθειας και το μοτίβο της επανάληψης του μυθολογικού παρελθόντος διαπιστώνεται ότι μπορούν να επηρεάσουν τη λειτουργία των δυνάμεων και αντίστοιχα επηρεάζονται και από αυτές.
Vortex Circular Dichroism: An experimental technique to assess the scalar/vectorial regime of diffraction
Authors: Zambrana-Puyalto Xavier , De Angelis Francesco , D'Ambrosio Vincenzo
Published: December 2022

Background: In classical electrodynamics, light-matter interactions are modelled using Maxwell equations. The solution of Maxwell equations, which is typically given by means of the electric and magnetic field, is vectorial in nature. Yet it is well known that light-matter interactions can be approximately described in a scalar (polarization independent) way for many optical applications. While the accuracy of the scalar approximation can be theoretically computed, to the best of our knowledge, it has never been determined experimentally. Here, we show that the vectoriality of diffraction can be probed with a new technique: Vortex Circular Dichroism(VCD).

Methods: We measure the differential transmission of left and right circularly polarized vortex beams through a set of single circular nano-apertures with diameters ranging from 150 to 1950 nm. We observe that VCD > 0 for smaller diameters, VCD ≲ 0 for intermediate values and VCD ≈ 0 for larger values of the diameter. We also carry out Mie Theory simulations for spheres with the same diameters as the nanoholes and observe that the theoretical and experimental VCD values follow the same trend line.

Results: We relate VCD ≠ 0 to a vectorial diffraction, and VCD ≈ 0 to a scalar one. This is corroborated by the simulations, which show that a diffraction process characterized by a VCD ≈ 0 (VCD ≠ 0) is polarization-independent (polarization-dependent).

Conclusions: Overall, our results give a wealth of evidence that VCD allows for the experimental assessment of the scalar/vectorial regime of diffraction.

Authors: Matczak Andrzej , Szymańska Daniela
Published: December 2022

The purpose of this study is to identify the impact that the COVID-19 pandemic had on the tourism sector in Poland in terms of the tourist mobility of Poles, i.e., on the volume and nature of tourist trips of Polish residents. It is based on a comparison of the numbers and natures of tourist trips made during the pandemic (2020–21) against the preceding period (2018–19). This study is based on data from Statistics Poland collected from several hundred thousand participants (an average of over 136,000 people surveyed annually). The study discusses changes in: Polish residents’ level of participation in tourist trips; the number and breakdown of tourist trips; and the reasons/purposes for tourist trips. In addition, changes in the breakdown of transport used during tourist trips are shown. Changes observed in tourist travel expenses from 2018 to 2021 are also discussed. Another subject of our analysis is changes in tourist travel destinations and the seasonality of these trips.
Current state of knowledge concerning experimental applications for deep brain stimulation in specific neurologic and psychiatric disorders
Authors: Senger Michał , Doruch Patrycja , Kędziora-Kornatowska Kornelia
Published: December 2022

Introduction and objectives. Deep brain stimulation  (DBS) is an invasive treatment method of certain neurologic and psychiatric disorders. It relies on sending external electrical stimulus to specific targets within the brain, causing change in their functioning. DBS is an approved management procedure, for instance in Parkinson’s Disease or Obsessive-compulsive disorder. Currently, studies are being conducted on the possible utilization of DBS in other disorders, especially exhibiting resistance for standard treatment. The objective of this study, is to present the state of knowledge concerning experimental usage of DBS in specific disorders. The following study is based on the review of scientific literature for the years 2000 – 2022.

State of knowledge. Regarding experimental applications, DBS is being used among others in Tourette’s Syndrome, Huntington’s Disease, Depression and Alzheimer’s Disease. The review of the literature allows to gather data concerning initial patients selection, mechanism of action, potential benefits and thus far noted adverse effects. Evaluation of therapy efficacy is mostly limited, due to short observation periods and lack of unified patient qualification criteria for the operation. 

Conclusion. Deep brain stimulation is a management method, in many cases acknowledged as safe and efficient. It is observed to have a beneficial impact on the disorders described in the following article. However, the approval of DBS as a conventional treatment requires improvement of many factors decisive of therapeutic success. Conduction of more randomised clinical trials in the future, may be helpful in achieving this objective.
Nutritional treatment in chronic kidney disease - review article
Authors: Orczykowski Maciej , Oleszczuk Rafał , Mendocha Jakub , Grzebalska Agnieszka
Published: December 2022

INTRODUCTION: Chronic Kidney Disease (CKD) is a condition affecting nearly 16% of the population. It is a disease that cannot be completely cured with modern medical capabilities. However, it is possible to halt the progression of the disease and postpone renal replacement therapy through pharmacotherapy. In order to monitor the progression of the disease, GFR should be determined.        PURPOSE OF THE WORK: This article reviews the potential impact of typical Western diet and eating habits on the occurrence and progression of chronic kidney disease. Reducing the intake of animal protein, foods rich in sodium potassium and phosphorus, and increasing the intake of fruits, vegetables and fiber help prevent or delay end-stage renal disease. The literature on the role of a low-protein plant-based diet in patients with CKD was also reviewed.        DESCRIPTION OF THE STATE OF KNOWLEDGE: In addition to pharmacological methods, whose main goal is to reduce proteinuria and control blood pressure, drug therapy can be supported by non-pharmacological methods. One of them is the use of a low-protein diet and adequate provision of macro- and micronutrients in the diet.         SUMMARY: In order to support pharmacotherapy in the treatment of chronic kidney disease, the use of an appropriate diet plays an important role. According to the literature, the most important is restriction of protein supply, weight reduction in obese patients and supplementation of micronutrient deficiencies that occur.

Malware-infected operating systems may experience system damage, files or loss of important data. Ransomware is a type of malware that works by attacking the internet network and then encrypting the victim's computer. So that the victim can access his computer again, the victim is asked to redeem (ransom) with some money in the form of Bitcoin. One of them is GandCrab. Gandcrab is a very powerful ransomware and only the creators of Gandcrab know the description of the encrypted files.Static analysis is done by importing malware samples into Virustotal, Dependency walker, PEStudio, Exeinfo PE, and PEexplorer tools to get the strings function, which will then be analyzed to find out how the GandCrab Ransomware works.This study analyzes the gandcrab ransomware malware using a static method. In the Virustotal tool, it was found that the malware sample file was detected as malware with a ratio of 60 out of 70 antimalware. Furthermore, it was found that GandCrab is in PE (portable executable) format, compiled using Microsoft Visual C++ and GndCrab accesses some DLL (dynamic link-library) functions.

Published: December 2022

Message is an expression that is formed from a thought and feeling, reality, opinion, experience that has happened or will come, and so on. Currently, the exchange of information carried out by both the sender and the recipient has used several social media applications, such as whatsapp, telegram, line, and many more. Messages sent and received through social media applications must be connected to the internet network for the communication process in which the message can be stolen by irresponsible parties, because these parties are also connected to the same internet network. One way that can be done so that the message sent is maintained and more secure, the process of securing the data and information contained in the message is carried out. The Linear Congruential Generator (LCG) algorithm will generate a random key value and convert it into Morse code form. The results obtained from the modification of the LCG algorithm and Morse code are very helpful in the encryption process which makes the encryption results obtained quite difficult to solve because in the encryption process one plaintext character is replaced with a dot sign (.) and a minus sign (-) on the ciphertext.
Pesan merupakan ungkapan yang terbentuk dari suatu pemikiran dan perasaan, realita, opini, pengalaman yang sudah terjadi atau yang akan datang, dan lain sebagainya. Saat ini pertukaran informasi yang dilakukan baik pengirim dan penerima sudah menggunakan beberapa aplikasi media sosial, seperti whatsapp, telegram, line, dan masih banyak lagi. Pesan yang dikirim dan diterima melalui aplikasi media sosial harus terhubung dengan jaringan internet untuk proses komunikasinya yang di mana pesan tersebut dapat dicuri oleh pihak yang tidak bertanggungjawab, dikarenakan pihak-pihak tersebut juga terhubung pada jaringan internet yang sama. Salah satu cara yang dapat dilakukan agar pesan yang dikirimkan terjaga dan lebih aman, dilakukan proses pengamanan data dan informasi yang ada didalam pesan tersebut. Algoritma Linear Congruential Generator (LCG) akan menghasilkan nilai kunci secara acak dan dikonversi ke dalam bentuk kode morse. Hasil yang didapatkan dari modifikasi algoritma LCG dan konversi kode morse dapat membantu untuk proses kriptografi yang membuat hasil enkripsi pesan cukup susah untuk dibaca karena dalam proses enkripsi pesan tiap-tiap karakter plaintext akan dikonversikan dengan tanda titik (.) dan tanda kurang (-) pada cipherteksnya.
Alat Pengecek Sampah Pendaki Gunung Berbasis Raspberry Pi 3 dan Barcode Scanner
Authors: Maulana Fadli , Widodo Nuryono Satya
Published: December 2022

The problem that is often encountered on many hiking trails is the lack of environmental awareness from the climber, which leads to trash littering. This study aims to design and develop a Raspberry Pi 3 Based Mountaineer Garbage Check Tool and Barcode Scanner that can help mountain managers to overcome the amount of garbage on the mountain. Raspberry Pi 3 is used to run various functions that can execute programs against an application. A Barcode scanner is used to read the code on the barcode. After the barcode scanner reads the code on the barcode, the code will be sent to the Raspberry Pi 3 and displayed on the monitor. This tool requires Java Netbeans, used to create applications in which there are various kinds of menus, including the Data Menu, Data Items, and Reports. The results of the application test in this study indicate that all forms can run well according to their respective duties and functions.

Authors: Zibordi Marcos Antonio
Published: December 2022

O objetivo deste artigo é explicitar as omissões de informações e deslizes éticos do jornalista Joseph Mitchell na feitura dos dois perfis do boêmio Joe Gould. A abordagem utiliza o método comparativo e conceitos de ética jornalística, análise narrativa e da linguística. Com esses procedimentos e aportes, demonstramos que, ao contrário de serem modelares para o gênero, por sua celebrada qualidade, os dois perfis de Joe Gould são exemplos daquilo que deve ser evitado na feitura de textos jornalísticos biográficos.
O NORTE BRASILEIRO NARRADO: passeios dramatúrgicos e identitários por uma região sub-representada pela telenovela
Authors: Santana dos Santos Rodrigues Leonardo , Perencin Tondato Marcia
Published: December 2022

Propomos que as escolhas dos cenários para as telenovelas evidenciam relações de poder e desigualdades inter-regionais no Brasil, pelo fato de que determinadas regiões, detentoras de uma hegemonia sociocultural e midiática, costumam ser mais representadas ficcionalmente que outras. Nesse contexto, chamamos atenção para uma sub-representação do Norte, já que, nas duas primeiras décadas deste século, apenas três novelas da Rede Globo foram ambientadas na região. Frente a essa sub-representação, buscamos entender de que maneira as obras exploram e concebem o Norte em termos identitários.

Published: December 2022

III-nitride nanowire (NW) LEDs have been intensively studied for
several emerging applications. However, the performance of these LEDs
is still limited due to many factors. A leakage current may cause idle
power consumption and affect the reliability and luminescence
efficiency of the devices. Hence, it is one of the most important
limiting factors from an application point of view. In this context,
we have experimentally observed temperature-dependent forward and
reverse leakage current–voltage characteristics of InGaN/AlGaN
NW-based red microLEDs. The characteristic curves are fitted using
different constant parameters such as the space charge term, zero bias
current, and the characteristic energy. They are found to have error
bars of less than 10%. The extra space charge term is believed to be
due to inherent space charges trapped with the NWs and presents at
every instance of the operation of the diode. The characteristic
energy and ideality factors are compared to the reported values. An
Arrhenius plot is used to calculate the thermal activation energy in
the high- and low-temperature regions for both bias conditions. Our
results show that the voltage-dependent activation energy is found to
be about double in the case of the forward bias compared to that of
the reverse bias in all voltage ranges. However, in a high voltage
regime, the magnitudes of these parameters are almost four and six
times greater for the forward and reverse biases, respectively,
compared to those in the lower voltage regions. This study presents
vital insight into the design and fabrication of high-performance
NW-based LEDs.
Performance of bit error rate of laser beams for LIDAR used in marine atmospheric weak turbulence
Authors: Gerçekcioğlu Hamza
Published: December 2022

The performance of laser beams is investigated for light detection and ranging (LIDAR) systems in marine weak atmospheric turbulence by using the Rytov method. Formulation, on-axis, of the scintillation indices of LIDAR systems, which is obtained for plane, collimated Gaussian, and spherical beams, is appraised for average bit error rate (BER) by utilizing the log-normal distributed intensity. Values, obtained for these beams, are checked against source sizes, target sizes, normalized target size parameters, propagation lengths, and the average signal-to-noise ratio (SNR) for specified parameters. It is observed that the target size that minimizes the scintillation index is independent of the source size. The target size minimizing scintillation index is approximately

. Variations in source size and target size values, independently of each other, affect the scintillation index and the performance of marine LIDAR system links. The contribution of the outer scale turbulence to the deterioration is more evident than the inner scale turbulence.
Concept of enhanced frequency chirping for multi-pass cells to improve the pulse contrast
Authors: Benner Maximilian , Karst Maximilian , Amaya Mendez Cristina , Stark Henning , Limpert Jens
Published: December 2022

The technique of enhanced frequency chirping can be implemented in multi-pass cells to significantly improve the temporal contrast without a penalty in efficiency. In contrast to waveguides, multi-pass cells offer the unique opportunity to tailor the nonlinear interaction, as spectral broadening and dispersion can mostly be spatially separated. By including additional dispersion through the multi-pass cell mirrors, the pulse form can be controlled, which leads to a decrease of the spectral modulations. A pulse possessing this smoother spectrum can be compressed to reach higher peak powers and have more energy in the main feature compared to classical multi-pass cells.
Macroscopic laser pulling based on the Knudsen force in rarefied gas
Authors: Wang Lei , Wang Shige , Zhao Qiuling , Wang Xia
Published: December 2022

Optical pulling is an attractive concept due to the counterintuitive feature, the profound mechanism underneath and promising applications. In recent ten years, optical pulling of micro-nano objects have been fully demonstrated. However, optical pulling of a macroscopic object is challenging. Herein, laser pulling of a macroscopic object is presented in rarefied gas. The pulling force is originated from the Kundsen force when a gauss laser beam irradiates a macroscopic structure composed of the absorptive bulk cross-linked graphene material and a SiO2 layer. A torsional pendulum device qualitatively presents the laser pulling phenomenon. A gravity pendulum device was used to further measure the pulling force that is more than three orders of magnitudes larger than the radiation pressure. This work expands the scope of optical pulling from microscale to macroscale and provides an effective technique approach for macroscopic optical manipulations.
Novel THPO variant in hereditary thrombocytopenia: A potential candidate variant for predisposition to myeloid neoplasm

Published: December 2022

Hereditary thrombocytopenia is a heterogeneous group of congenital disorders with a wide range of symptoms depending on the severity of platelet dysfunction or thrombocytopenia. Because of its clinical phenotypes and the bone marrow morphology associated with this condition, hereditary thrombocytopenia can be misdiagnosed as primary immune thrombocytopenia and myelodysplastic syndrome. Therefore, genetic evidence is necessary for the accurate diagnosis of hereditary thrombocytopenia. Refractory cytopenia of childhood is a subgroup of myelodysplastic syndrome that was added to the World Health Organization classification in 2008. To investigate the germline and somatic variants associated with refractory cytopenia of childhood, we performed targeted multigene sequencing in three patients with refractory cytopenia of childhood. Of the three patients, one progressed from megakaryocytic hypoplasia with thrombocytopenia, and targeted multigene sequencing revealed THPO variants in this patient and his sister. We propose that the monoallelic deletion of THPO is a potential candidate for germline predisposition to myeloid malignancy.
