Published: February 2022

El Accidente Cerebrovascular (ACV), representa uno de los principales problemas en la salud pública en todo el mundo. Una nueva herramienta empleada en rehabilitación es la estimulación transcraneal por corriente directa (tDCS) no invasiva. Se trata de técnica segura, ya que no se realiza ningún tipo de punción o perforación sobre el paciente. Esta técnica modula la excitabilidad o inhibición neuronal en áreas corticales específicas. En este estudio han participado 2 pacientes con ACV y sintomatología espástica e hipotónica (1:1) que recibieron un total de 10 sesiones de estimulación tDCS y terapia con dispositivo robótico. Se emplearon evaluaciones funcionales al inicio y final del tratamiento tales como, valoración del Índice Motor, escala STREAM y valoración Frenchay, además se registraron datos electromiográficos durante todas las sesiones. Tras la realización del tratamiento se analizaron todos los datos obtenidos tanto en las valoraciones funcionales como en las señales registradas obteniendo resultados positivos en referencia al control motor voluntario, disminuyendo o aumentando el tono muscular con el que partían de inicio los pacientes. Concluyendo este estudio en que la estimulación tDCS puede emplearse como una herramienta más al alcance del personal rehabilitador, la cual, puede combinarse con terapias alternativas como las generadas por un dispositivo robótico.

Interseccionalidad de derecha e ideología de género en América Latina
Authors: Ravecca Paulo , Schenck Marcela , Forteza Diego , Fonseca Bruno
Published: February 2022

Este artículo explora lo que denominamos interseccionalidad de derecha (ID). Al igual que la perspectiva académica y activista de la interseccionalidad, la ID atiende a la interrelación entre distintos ejes de posicionamiento social y desigualdad. Sin embargo, el contraste entre ellas no podría ser mayor, ya que la ID no moviliza intersecciones para cuestionar el poder, sino para legitimar el statu quo y naturalizar mecanismos de opresión. El artículo muestra la centralidad del tema de la “ideología de género” en la ID. Para ello, analiza el discurso de los politólogos Agustín Laje y Christian Rosas. El estudio utiliza métodos mixtos: análisis estadístico de tuits (correlaciones y análisis de sentimientos) e interpretación de libros, videos, arengas y conferencias. Para consolidar los hallazgos, la exploración se extendió a otros/as 18 activistas y políticos/as. Concluimos que la potencia narrativa de la extrema derecha hoy radica en su carácter interseccional, en la apelación a las emociones, en el uso de la simplificación y en la reproducción obstinada y efectiva de los aspectos más conservadores del sentido común y del liberalismo.
Opracowanie metodyki oznaczania WWA w próbkach gleb z wykorzystaniem chromatografii cieczowej HPLC
Authors:   Instytut Nafty i Gazu – Państwowy Instytut Badawczy, Wojtowicz Katarzyna
Published: February 2022

W artykule przedstawione zostały zagadnienia związane z opracowaniem metodyki chromatograficznego oznaczania wielopierścieniowych węglowodorów aromatycznych w próbkach gleb. Do tego celu stosowano chromatograf cieczowy serii Vanquish Core firmy Thermo Scientific wyposażony w detektor fluorescencyjny (FLD) i detektor UV-ViS. W ramach prowadzonych badań określono optymalne parametry pracy chromatografu, takie jak: objętość próbki, rodzaj eluentów, szybkość przepływu eluentów, gradient eluentów w trakcie analizy chromatograficznej i czas analizy, oraz dobrano kolumnę chromatograficzną umożliwiającą selektywny rozdział analitów. Następnie wykonano kalibrację układu chromatograficznego i walidację metody analitycznej oznaczania WWA, stosując roztwory kalibracyjne opracowane na podstawie roztworu wzorcowego PAH-Mix nr ref. 722393 firmy Macherey-Nagel. Walidacja metody analitycznej obejmowała wyznaczenie liniowości, odchylenia standardowego, względnego odchylenia standardowego, granicy wykrywalności (LOD) i granicy oznaczalności (LOQ) badanych WWA. Chromatograficzna metoda identyfikacji WWA w próbkach gleb wymaga przeprowadzenia analitów z matrycy stałej do matrycy ciekłej (etap izolacji), oczyszczenia próbki z substancji przeszkadzających oraz zagęszczenia ekstraktu (etap wzbogacania). W celu opracowania metody oznaczania WWA w próbkach gleb sprawdzono 3 metody przygotowania próbek do analizy chromatograficznej HPLC: metodę A (metoda QuEChERS), metodę B (ekstrakcja rozpuszczalnikiem w aparacie Soxhleta) i metodę C (ekstrakcja rozpuszczalnikiem wspomagana wytrząsaniem). Otrzymane ekstrakty były następnie oczyszczane na wybranym materiale sorpcyjnym: MgSO4 i PSA (metoda A), CN/SiOH (metoda B) i Al2O3 (metoda C). Do przetestowania wybranych metod przygotowania próbek gleby do analizy chromatograficznej HPLC wykorzystano glebę wzorcową PAHs by HPLC40g (SQC017-40G) firmy Sigma Aldrich, o znanych stężeniach analitów. Oczyszczone ekstrakty poddano analizie chromatograficznej HPLC, obejmującej identyfikację oraz ilościowe oznaczenie poszczególnych WWA, oraz obliczono stopnie odzysku analitów. Na podstawie analiz chromatograficznych i stopni odzysku wytypowano optymalną metodykę przygotowania próbek gleb do analizy chromatograficznej pod kątem oznaczania wielopierścieniowych węglowodorów aromatycznych. Opracowaną metodykę oznaczania WWA w próbkach gleb przetestowano na rzeczywistych próbkach gruntu pobranych z 2 otworów badawczych zlokalizowanych na terenie kopalni ropy naftowej usytuowanej w południowo-wschodniej Polsce.

Przed wyjazdem do Stambułu. Kilka uwag na temat przygotowania misji Stanisława Chomentowskiego, wojewody mazowieckiego, do Porty Ottomańskiej w 1712 roku
Authors: Perłakowski Adam
Published: February 2022

The purpose of Stanisław Chomentowski’s mission as the Grand Ambassador to the Sublime Porte in 1712–1714 was to confirm the terms of the Treaty of Karlowitz, signed in 1699, and to reduce the political tension between the Polish-Lithuanian Commonwealth and Turkey, which in late 1712 and throughout almost entire 1713 even threatened to erupt in an armed conflict between the two states. Considering the course of the mission, the difficulties in completing it, and even the temporary restriction of the Polish diplomat’s freedom on the territory of the Ottoman state, its results should be regarded as definitely positive. Chomentowski’s visit to Turkey, where he was supported by Augustus II’s other diplomats, Franciszek Goltz (starosta of Śrem) and Jan Spiegel, resulted in averting the Turkish threat and renewing the terms of the Treaty of Karlowitz. The three missions, conducted by Chomentowski, Spiegel and Goltz, should be studied in the context of Augustus II’s one large-scale diplomatic action, which ended successfully. It also proves that the work of the Polish diplomatic service in the times of the kings from the House of Wettin, about which historians, paradoxically, do not have a very high opinion to this day, was actually quite effective.

Economic Analysis of Tractor Powered Manure Pulverizer cum Applicator over Traditional Manure Application Practices
Authors: Mohan S. Sai , Babu P. , Jayan P.R.
Published: February 2022

Background: A well-managed manure is a valuable resource in providing nutrients for crop production. Farmers usually follow manual manure application practices which involves lot of drudgery and physical stress to pulverize as well as to apply in field. Also traditional practices results in a reduced field capacity along with higher cost of application. So there is a need to create a medium between the farmers and manure application practices by introducing manure pulverizers and applicators. Hence a study was undertaken to analyze the economic impact of a tractor powered manure pulverizer cum applicator over traditional practices. Methods: A manure pulverizer cum applicator helps in managing the manure by simultaneous pulverization and application in the field as basal application. On the other hand traditional practices involve manual dumping, clearing of lumps and spreading them in the field which require more than 3 labours to cover an acre in a day. Cost incurred with both manual and mechanical practices were calculated in terms of rupees per hour and rupees per hectare of operation. Result: The actual field capacity and efficiency of manure pulverizer cum applicator was observed to be 0.311 ha h-1 and 86.5% at a forward speed of 2.0 km/h-1. The cost of manure pulverizer cum applicator alone was Rs. 64,000. Cost of operation of manure pulverizer cum applicator as an attachment to tractor was found to be 1943.5 Rs ha-1. Cost of manual manure application followed by manure pulverization was noted as 4662.2 Rs ha-1. Saving in cost of operation was more than Rs. 2700 with tractor operated manure pulverizer cum applicator over manual application practices. The benefit-cost ratio of the developed machine was 1.4:1.

Published: February 2022

Background: Capsicum (Sweet pepper or Bell pepper), Capsicum annuum L. also popularly called as Simla mirch in India is one of the leading vegetables grown in open conditions as well as under protected conditions. It is attacked by various insect and mite pests from seedling to fruiting stage. The damage caused by Spodoptera litura (Fabricius) during flowering and fruit formation is the most concern and farmers everywhere feel the need to protect such high value crops from any type of damage caused by insect pests. Methods: The trial was conducted under poly house condition during kharif 2019 at horticulture garden, College of Agriculture, Rajendranagar, Hyderabad. The experiment was laid out in randomized block design (RBD) with eight treatments replicated thrice in a 7.5 m × 1 m plot size with a spacing of 45 cm × 40 cm. The capsicum hybrid WS 234 was raised as per the recommended package of practices except plant protection measures. The observations on pest incidence were recorded one day before treatment imposition as pre-treatment count. Post treatment counts were recorded at one, three, five and seven days after each chemigation/spray. Result: The present study indicated that treatment of cyantraniliprole 10.26% OD @ 90 g a.i. ha-1 applied through drip chemigation was effective by recording minimum larval population with lowest fruit damage over all the other treatments. The next best treatment was cyantraniliprole 10.26% OD @ 60 g a.i. ha-1 applied as foliar spray. The order of moderate effective treatments were drip applications of cyantraniliprole 10.26% OD @ 60 g a.i. ha-1 greater than cyantraniliprole + thiamethoxam 19.8+19.8 w/w @ 64 g a.i. ha-1 greater than cyantraniliprole + thiamethoxam 19.8+19.8 w/w @ 32 g a.i. ha-1 greater than imidacloprid 70 WG @ 50 g a.i. ha-1 greater than imidacloprid 70 WG @ 25 g a.i. ha-1.
Effect of Tillage on Weed Shift and its Managements: A Review
Authors: Selvakumar S. , Ariraman R.
Published: February 2022

Tillage is the most important age old practice, which is usefull to create favourable seed bed for sowing of seeds. It also plays a significant role in weed species persistence and its distribution in agriculture fields. Summer plough kills the weed seeds by exposing it to the sun light. Deep tillage helps for the development of enforced dormancy by burring the newly shredded seeds in the deeper layer of soil. Till now no herbicide is available to kill the weed seeds, tillage improves nitrogen mineralization thus in turn enhance the germination of weed seeds. After weed seed’s germination, controlling can be done easily with either spraying of herbicides, mechanical and manual means. Now a day’s conservation tillage or zero tillage concept is getting picking up. So it is highly important to study the effect of reduced tillage on weeds. Most of the research evidences found that under reduced tillage condition, weed seed accumulation is higher in upper layer of the soil. Annual weed population is predominant in reduced or no tilled soil. In no tillage system before planting soil was applied with non-persistent non selective herbicides to control weeds effectively.

Published: February 2022

El sistema Bus Rapid Transit (BRT) es uno de los modos de transporte más demandados en los últimos años. Este sistema de transporte cuenta con estaciones para los usuarios y múltiples líneas de buses en una determinada ciudad. Sin embargo, el desorden en el recorrido de los usuarios a lo largo de la estación y la alta densidad e interacción peatonal generan largos tiempos de espera para los usuarios desde que entran a la estación hasta su embarco al bus. La presente investigación propone una gestión de la movilidad peatonal, la cual mediante la canalización de flujos peatonales y adaptación de entradas y salidas de la estación tiene por objetivo principal reducir los tiempos de espera de los usuarios dentro de la estación. Se realizó visitas a una estación de BRT en la ciudad de Lima para medir los tiempos de espera de los usuarios dentro de esta. La recolección de información nos permitió establecer el horario de más concurrencia peatonal y demostrar que los usuarios pueden demorar más tiempo dentro de la estación que en el bus. La propuesta fue simulada en el software Vissim para poder determinar su eficiencia. Los resultados muestran que se redujo los tiempos de espera de los usuarios dentro de la estación en un 25%. Por otro lado, el valor de la densidad peatonal y los puntos de conflicto entre peatones disminuyeron en un 44% y 73% respectivamente. Finalmente se obtuvo un aumento en la velocidad peatonal de los corredores en un 37%.

Civil Society and Educational Development: the Latin American Experience
Authors: D’yakova L.
Published: February 2022

Civil society organizations, whose activity increased in the first decade of the 21th century, play a significant role in improving and correcting public policies at the local level. The article examines the ideological principles and practical activities of NGOs in the field of education, represented by both regional and local organizations, as well as interaction between the state, society and business in promoting joint projects, increasing the inclusiveness and quality of educational systems, and developing new approaches. Special attention is paid to non-state educational institutions that offer a possibility of additional training, as well as alternative universities created by Indian organizations to implement the principles of intercultural dialogue and genuine equality. Activities of Latin American civil society have a significant impact on the social life of the region. It is a complex social phenomenon of particular interest. The author acknowledges that NGOs are not able to solve most urgent problems of education as they remain a subject to a targeted strategy of the state, which consists in attempts to radically improve the entire system, ensuring equal chances for children from poor backgrounds. Nonetheless, by exerting a significant impact on public life in the region, minimizing the costs and failures of state policies, these NGOs play an important stabilizing function as they develop an alternative and additional education and provide opportunities to vulnerable social groups. At the new stage of development, in the conditions of disillusionment with the state’s capabilities, the social role of civil society will inevitably increase, expanding the social space of creative activity, complementing, correcting and improving public policies.
The Russian Economic Barometer: Experience of Studying Market Reforms in Russia
Authors: Egorov A. , Bashirova I. , BELYANOVA E.
Published: February 2022

The article is dedicated to the 30th anniversary of “The Russian Economic Barometer” – an independent research program being implemented under the auspices of the Institute of World Economy and International Relations. The program was launched in the end of 1991 with the purpose to conduct regular business surveys in order to compensate for the shortage of statistical data revealing changes in the behavior of the Russian industrial enterprises during economic transition. The article describes the distinctive features of REB data base which at present contains over 200 monthly indicators of enterprise performance and changes in the business environment. The main advantages of REB time series consist in the continuity of information gathering throughout a period of 30 years and immutability of the methodology for calculating indicators. The other advantages of REB data base are a short time span from conducting a survey to the data release and availability of indicators that are difficult or impossible to measure by conventional methods such as factors limiting output and investment, capacity and labor utilization rate, managers’ assessments of the current situation of their enterprises and expectations for the nearest future, their views on the overall economic situation and the economic policy of the government. Furthermore the authors outline the stages of the development of the research program, key studies and major achievements as well as current problems and challenges for the future. Special attention is paid to the evolution of the main end users of REB statistical information: from directors of enterprises – survey participants, to whom REB helped to cope with new realities at the early stage of the transition period, and foreign researchers, who experienced shortage of statistical information on developments in the Russian industrial sector – to the public authorities and scientific community of Russia which use REB statistics as a reliable source of independent data supplementing the official statistics. The regularly updated time series of REB indicators and analytical articles are published in the quarterly bulletin “The Russian Economic Barometer” available on the IMEMO website both in Russian https://www.imemo.ru/publications/periodical/reb-quarterly and in English https://www.imemo.ru/publications/periodical/reb-quarterly-eng.
Turkey and Azerbaijan: One Nation – One State?
Authors: Avatkov V.
Published: February 2022

The article scrutinizes Turkish-Azerbaijani key areas of cooperation – political, economic, military-technical, cultural and humanitarian. For instance, in addition to intensive interaction at the level of high-ranking political elites, Azerbaijani-Turkish unity in the political context is largely built on the basis of classifying foreign policy partners into common friends and common enemies (the “friend-foe” principle). Thus, both Ankara and Baku are building friendly relations with the Turkic states of Central Asia. At the same time, Armenia acts as a common “enemy”. In the military sphere, both states seek to form Turkey-oriented militarized structures and, moreover, to create a unified Turkic army in the long term. The nature of economic relations between Azerbaijan and Turkey is largely based on a competitive basis. Energy acts as a unifying and at the same time a divisive factor since both states strive for leadership in this area, seeking to occupy a special place in the regional energy market. In the cultural and humanitarian sphere, the unfolding Turkey-centric integration is of particular importance. The author comes to the conclusion that nowadays the bilateral relations between Turkey and Azerbaijan are characterized by the “merging” of the two countries into a single Turkey-centric space, which manifests in almost all fields of interaction. The Republic of Turkey seeks to influence Baku in order to make it a reference point of the “Turkic world” under its auspices. This trend is most likely to strengthen in the future.
Relationships of Paid and Unpaid Internships, and Source for Obtaining, to Early COVID-19 Stage Anticipated Employment Outcomes
Authors: Blau Gary
Published: February 2022

This study investigated the relationships of paid and unpaid internships to anticipated employment outcomes for graduating college business students. It also investigated the self-reported source(s) by which these students had obtained their internship(s). In May of 2020, 445 graduating business undergraduates filled out an online survey, for which there was complete data for 405 students. Although most of the internships were pre-pandemic, the anticipated employment outcomes by graduation were in the early stage of the COVID-19 pandemic. Three dichotomous response anticipated employment outcomes were measured: securing a full-time job; securing a full-time job that consistent with one’s major; and being self- employed. Results were that students with at least one paid internship were more likely to anticipate securing a full-time job and securing a full-time job consistent with their major versus students without a paid internship. In addition, students with at least one paid internship were less likely to see themselves being self-employed versus students without a paid internship. However, there were no relationships for students having at least one unpaid internship, versus no unpaid internship, to these anticipated full-time employment outcomes. Students with at least one unpaid internship were more likely to see themselves being self-employed by graduation versus students without an unpaid internship. Surprisingly, the general source of “on my own” was the dominant method reported by students for obtaining both paid and unpaid internships.

MicroRNAs (miRNAs) are a class of small non-coding RNAs, which function as regulators of gene expression and contribute in numerous physiological processes. However, little is known referring to miRNAs function in insect chemosensation. In the current study, nine small RNA libraries were constructed and sequenced from the antennae of nymphs, adult males and females of Apolygus lucorum. In total, 399 miRNAs were identified including 275 known and 124 novel miRNAs. Known miRNAs were classified into 71 families, amongst which, 23 families were insect-specific. Expression profile analysis showed that miR-7-5p_1 was the most abundant miRNAs in the antennae of A. lucorum. Altogether, 69708 target genes related to biogenesis, membrane and binding activities were predicted for 399 miRNAs. Particularly, 15 miRNAs were found to target 16 olfactory genes. These miRNAs could be involved in regulation of olfactory-associated genes ex-pression. Comparing the antennae of nymphs, adult males and females, 94 miRNAs were found to be differentially expressed. The expression levels of some differentially expressed miRNAs measured by qPCR were consistent with sequencing results. This study provides a global miRNAs transcriptome in the antennae of A. lucorum and valuable information for further investigation on miRNA-mRNA interactions, especially the functions of miRNAs in regulating chemosensation.

Colorectal cancer (CRC) is the third most common type of cancer and the second leading cause of cancer deaths worldwide. Surgery or surgery plus radiotherapy and/or chemotherapy for patients with metastatic CRC (mCRC) were accepted as the main therapeutic strategies until the early 2000s, when targeted drugs, like cetuximab and bevacizumab were developed. The use of targeted drugs in clinical practice has significantly increased patients’ overall survival. To date, the emergence of several types of targeted drugs has opened new possibilities and revealed new prospects for mCRC treatment. Therapeutic strategies are continually being updated to select the most suitable targeted drugs based on the results of clinical trials that are currently underway. This review discusses the up-to date molecular evidence of targeted therapy for mCRC and summarizes the Food and Drug Administration-approved targeted drugs including the results of clinical trials. We also explain their mechanisms of action and how these affect the choice of a suitable targeted therapy.

Published: February 2022

Burning woody biomass for energy is gaining attention due to environmental issues associated with fossil fuels and carbon emission. The carbon released from burning wood is absorbed by plants and is carbon neutral. The purpose of this study was to investigate the combustion characteristics (heat calorific values and ash contents) of three timbers: Araucaria cunninghamii, Instia bijuga and Pometia pinnata and recommend for fuelwood. The test samples were sawdust particles (treatment) and solid woods (control) extracted from the heartwoods. The sawdust particles were oven-dried, sieved and pelletized into pellets using a hand-held pelletizing device, thus, forming cylindrical dimension (volume 1178.57 mm3, oven dry density 0.0008 g/mm3). While the solid woods were cubed and oven-dried (volume 1000.00 mm3, oven dry density 0.001 g/mm3). Prior to combustion in a semi-automatic bomb calorimeter, 90 test specimens (15 replicates per treatment and control per species) were conditioned to 14 % moisture content (at temperature 105 ºC) and weighed to a constant (unit) mass (1.0 g). The heat energy outputs and ash residues (of treatments) were analyzed statistically. The results indicated variability in heat energy outputs and ash residues between test specimens of the three species. Comparatively, the treatment specimens of A. cunninghamii produced higher calorific value (18.546 kJ/g) than the control (18.376 kJ/g) whilst the treatment specimens of I. bijuga and P. pinnata generated lower heat calorific values (17.124 kJ/g and 18.822 kJ/g) than the control (18.415 kJ/g and 20.659 kJ/g), respectively. According to ash content analysis, A. cunninghamii generated higher residues (6.3%) followed by P. pinnata (4.5%) and I. bijuga (2.8%). The treatment specimens of the three species could not meet the standard heat energy requirement (20.0 kJ/g) and thus, were unsuitable for fuelwood. However, the control specimens of P. pinnata generated equivalent heat energy (20.659 kJ/g) and could be a potential fuelwood.

Background:

The Accolade TMZF is a tapered-wedge cementless metaphyseal-coated femoral stem that was widely utilized from 2002 to 2012. In recent years, there have been reports of early catastrophic failure of this implant. The purposes of the present study were to establish the long-term survival of this stem and to analyze patients who underwent aseptic revision to understand the causes and risk factors for failure.

Methods:

We retrospectively reviewed the records of all patients who had undergone primary total hip arthroplasty with use of an Accolade TMZF stem at a high-volume arthroplasty center. The causes and timing of revision surgery were documented. Survivorship analysis was performed with use of Kaplan-Meier curves to determine the overall and aseptic survival rates at the time of the latest follow-up. Patient and implant factors commonly associated with aseptic failure were extracted, and a Cox proportional hazards model was used.

Results:

A consecutive series of 2,609 patients who had undergone unilateral primary total hip arthroplasty with use of an Accolade TMZF femoral stem were included. The mean time from the primary procedure was 11.3 years (range, 0 days to 19.4 years). The cumulative survival rate was 95.5% ± 0.1% at the time of the latest follow-up. One hundred and seven patients underwent revision surgery, with aseptic loosening of the femoral component being the most common cause of aseptic failure in this cohort (33 of 2,609; 1.3%). Smaller femoral size and larger femoral head offset were independent risk factors for aseptic failure.

Conclusions:

To our knowledge, this is the largest series representing the longest follow-up of this tapered-wedge cementless femoral implant. Despite early concerns, the Accolade TMZF stem had excellent survivorship in this cohort. Trunnionosis as the cause for revision surgery was rare.

Authors: MacNeill Justin J , Linnes Jacqueline C , Rodriguez Natalia M
Published: February 2022

Background: The COVID-19 pandemic thrust people living with HIV (PLWH) and HIV/AIDS service organizations into an environment ripe with uncertainty. This study examined Indiana AIDS services provider perceptions of how COVID-19 affected the overall health and access to care of their clients, and how the organizations prepared for, adapted, and responded to the needs of PLWH during the pandemic. Methods: Guided by the socioecological model, fifteen semi-structured interviews were conducted with ten different HIV/AIDS service organizations across the state of Indiana. Results: Despite the profound disruptions experienced by HIV programs, HIV/AIDS service organizations responded quickly to the challenges posed by the COVID-19 pandemic through myriad innovative strategies, largely informed by prior experiences with the HIV epidemic. Conclusions: The lessons provided by HIV/AIDS service organizations are invaluable to informing future pandemic response for PLWH. Service delivery innovations in response to the COVID-19 crisis may provide insights to improve HIV care continuity strategies for vulnerable populations far beyond the pandemic.

Purpose: To evaluate the indications and postoperative complications of our new modified Duckett urethroplasty.Methods: A total of 133 patients with proximal hypospadias who underwent repair of the modified Duckett urethroplasty from February 2016 to February 2021 were reviewed. The median age of patients was 3 years (range 1-16). All patients had severe chordee. One senior experienced pediatric urologist performed all the surgeries. Catheter was removed 14 days after the surgery.Results: The location of the urethral meatus was proximal penile in 26 patients (19.5%), penoscrotal in 60 (45.1%), scrotal in 31 (23.3%), and perineal in 16 (12.0%). The mean length of the urethral defect was 4.5 cm (range 2.5-10). The median duration of follow-up was 46 months (range 8-67). Complications occurred in 31 patients (23.3%), including urethra-cutaneous fistula in 22 (16.5%), urethral stenosis in 7 (5.3%), and urethral diverticulum in 2 (1.5%). No recurrent chordee were found in all cases. All patients who developed complications were treated successfully at our hospital. Conclusion: Our modified Duckett urethroplasty showed functionally and cosmetically favorable outcomes, with a lower incidence of postoperative complications. To the best of our knowledge, the novel Duckett technique is a feasible and suitable option for patients who suffer from proximal hypospadias with severe chordee and dysplasia of the urethral plate.

Background: The number of Parkinson's patients (PD) undergoing total knee arthroplasty (TKA) is increasing. The purpose of the study was to characterize quality of life (QOL) outcomes for patients with coexisting PD and knee osteoarthritis (KOA) following TKA.Methods: Patients with coexisting PD and KOA undergoing TKA between June 2014 and June 2020 were included. These patients were matched to controls with KOA alone by age, gender, basic social background information and Knee society score（KSS）. The primary measure was to assess the QOL by the absolute changes in the EuroQOL5-Dimensions (EQ-5D), Pain and Disability Questionnaire (PDQ), and Patient Health Questionnaire-9(PHQ-9) at the last follow-up (LFU). Secondary measures were changes in QOL that exceeded the minimum clinically important difference value (MCID). Data on the health status and QOL of all patients were collected. Simple and multivariate regression analysis was used to evaluate the impact of PD on their QOL.Results: Twelve KOA patients with PD were compared with 48 controls. Control patients experienced QOL improvement across all three measures：EQ-5D index (0.545-0.717, P <0.01), PDQ (81.1-52.3, P < 0.01) and PHQ-9(8.22-5.91, P < 0.01) were significantly improved at the LFU; while in patients with PD, only PDQ (91.0-81.4, P =0.03) slightly improved. There were significant differences in the improvement of QOL between PD patients and the control group through EQ-5D (0.531 vs.0.717, P< 0.01) and PDQ (81.4vs.52.3, P <0.01) at the LFU.Conclusion: TKA has no benefit of QOL beyond a slight improvement in pain-related disability in the KOA patients with PD.
