Published: August 2022

BACKGROUND: Even though literature indicates presence of weak hip abductors and lateral rotators’ in Patellofemoral Pain (PFP), studies evaluating the effect of hip abductors and lateral rotators strengthening to improve knee function and quality of life in PFP are limited. OBJECTIVE: This study systematically reviews and meta-analyzes the best evidence on the therapeutic value of strengthening hip abductors and lateral rotators muscles for treating PFP with a presumptive hypothesis that strengthening hip muscles stabilizes the patellofemoral joint, relieves pain, and enhances knee functions. METHOD: Medline, EMBASE, CINAHL, PEDro and PubMed Central databases were searched between January 1994 and September 2019 using the PICOS tool. The methodological quality of the selected studies were appraised individually using the 20-item McMaster Critical Review Form for Quantitative Studies. Supplemental quality appraisal of randomized controlled clinical trials performed using the Cochrane Collaboration’s ‘Risk of bias’ quality criteria. Data on patient population demographics, interventions, duration of intervention, and outcome measures were extracted and summarized in evidence tables and descriptive analysis. Meta-analyses under both fixed and random-effects models determined pooled effects size from appropriate RCTs. RESULTS: All fourteen studies demonstrated that hip muscle strengthening improved pain and knee function. All RCTs, except one, demonstrated that hip muscle strengthening is superior to quadriceps strengthening. Of the five RCTs assessing the additional effect of hip-quad versus quadriceps strengthening, four suggested that hip-quad strengthening is superior to standard quadriceps strengthening alone to improve PFP and knee function. CONCLUSION: In adult patients with PFP, strengthening hip abductors and lateral rotators’ have beneficial therapeutic effects than the conventional quadriceps exercises in improving knee pain and function both in the short- and long term. However, the present review data can be used to develop a standardized hip-quad protocol in the future.

Published: August 2022

BACKGROUND: Andersson lesion (AL) is a rare complication of ankylosing spondylitis (AS). Its clinical outcome of surgical treatment needs further exploration. OBJECTIVE: To evaluate the clinical and radiological outcomes of transforaminal thoracolumbar intervertebral fusion (TTIF) in the treatment of AS patients with thoracolumbar AL. METHODS: Fourteen patients with thoracolumbar AL who suffered from back pain, spinal instability or kyphotic deformity were retrospectively recruited. The clinical outcomes were evaluated with Visual Analog Scale (VAS) and Oswestry Disability Index (ODI). Radiological outcomes were measured with local kyphotic (LK) angle and general kyphotic (GK) angle. RESULTS: Before surgical treatment for the AL patients, their VAS score and ODI score was 8.0 ± 0.2 and 64.0 ± 6.9, respectively. After TTIF surgery, VAS score of the patients was improved to 2.4 ± 0.5 (p< 0.01) and ODI score was decreased to 17.0 ± 3.7 (p< 0.01). One patient with neurological deficit showed an improvement in the Frankel grade from C to D and all others were grated E-level before and after surgery. For radiological outcomes, patients’ LK angle was reduced from 18.5 ± 7.2 to 11.0 ± 6.4 (p< 0.01) and GK angle was reduced to 38.6 ± 8.8 from 42.8 ± 10.4 (p< 0.01) at the 1-year follow-up. CONCLUSION: For AS patients with thoracolumbar AL, we propose that TTIF is an effective and safe operative treatment, which can achieve good fusion, satisfactory radiological and clinical outcomes.

Published: August 2022

BACKGROUND: Navigation portable applications have largely grown during the last years. However, the majority of them works just for outdoor positioning and routing, due to their architecture based upon Global Positioning System signals. Real-Time Positioning System intended to provide position estimation inside buildings is known as Indoor Positioning System (IPS). OBJECTIVE: This paper presents an IPS implemented as a mobile application that can guide patients and visitors throughout a healthcare premise. METHODS: The proposed system exploits the geolocation capabilities offered by existing navigation frameworks for determining and displaying the user’s position. A hybrid mobile application architecture has been adopted because it allows to deploy the code to multiple platforms, simplifying maintenance and upgrading. RESULTS: The developed application features two different working modes for on-site and off-site navigation, which offer both the possibility of actual navigation within the hospital, or planning a route from a list of available starting points to the desired target, without being within the navigable area. Tests have been conducted to evaluate the performance and the accuracy of the system. CONCLUSION: The proposed application aims to overcome the limitations of Global Navigation Satellite System by using magnetic fingerprinting in combination with sensor fusion simultaneously. This prevents to rely on a single technology, reducing possible system failures and increasing the scalability.

Published: August 2022

BACKGROUND: Due to the COVID-19 pandemic, from April 2020 data collection for the Smoking and Alcohol Toolkit Study (STS/ATS) shifted from a face-to-face to a telephone survey. In March 2022 a parallel face-to-face survey was conducted alongside the telephone survey to explore whether the change in data collection to telephone affected key sociodemographic, smoking alcohol use indicators.

METHODS: Cross-sectional representative surveys (one telephone and one face-to-face) of adults aged 16+ in Great Britain. We estimated unweighted statistics and 95% confidence intervals for sociodemographic date. We estimated weighted prevalence statistics and 95% confidence intervals for selected smoking and alcohol use measures for Great Britain, England, Scotland and Wales separately, except nicotine product use, which was assessed for the overall Great Britain sample only.

RESULTS: In March 2022, 2,607 and 2,064 adults aged 16+ participated in respective telephone and face-to-face surveys for the STS/ATS. The unweighted age profile of the face-to-face wave was younger than the telephone wave but similar according to other sociodemographic variables. Weighted estimates in the telephone and face-to-face surveys differed by around one percentage point or less for response categories of daily smoker, non-daily smoker, pipe/cigar smoker, and stopped last year. There were differences in the estimates for never smoking and stopped more than a year ago between the surveys but the combined estimate for never or long-term ex-smoking was similar. Data on use of nicotine products by past-year smokers were similar between survey modalities. The estimates for people reporting an AUDIT score of 8 or higher, or an AUDIT-C score of 5 or higher, and attempting to cut down on drinking were similar between modalities. A higher proportion of respondents reported never drinking during the past year in the face-to-face survey compared with the telephone survey.

CONCLUSION: A parallel telephone and face-to-face survey wave of the STS/ATS yielded similar estimates for key sociodemographic, smoking and alcohol use measures. Differences between estimates are generally within expected limits given the uncertainty of month-to-month surveys.

Purpose: Due to the paucity of information regarding the lower limb biomechanics in running at slow speed, as well as the concentration of most previous studies on a single movement plane, this study aimed to investigate lower limb joint kinetics with increasing running speed. Methods: Twenty-eight runners were asked to stay on the treadmill at a bent velocity which was incrementally increased to 2.5 m/s, 3.5 m/s, and 4.5 m/s speeds. The three-dimensional joint moment and sagittal mechanical muscle power of the lower limb were calculated during the stance phase of running. Repeated measures analysis of variance (ANOVA) with Bonferroni post hoc test was used to examine the variables during running at various speeds. Results: The results showed that at the hip joint in the frontal plane, an adduction moment developed in the middle of the stance phase, and the highest peak adduction moment was obvious at the highest speed condition (4.5 m/s). Also, the time elapsed to peak in the highest speed condition was less than the others. In the transverse plane, although the 3.5 m/s-speed condition experienced the maximum external rotation peak moment, the 4.5 m/s-condition speed reached the internal status earlier than the two other speeds. In the sagittal plane, the highest speed condition showed the highest extension and flexion moments. Conclusion: Increasing running speed in runners leads to more kinetic output and mechanical power gradient.

Purpose: Osteoarthritis is a degenerative joint disease affecting synovial joints and damages joints due to stresses caused by an abnormality in any of the synovial joint tissues, including articular cartilage and subchondral bone, ligaments, menisci, periarticular muscles, peripheral nerves, and synovium. To compare the effect of sensory-motor training versus impairment-based training on pain and physical function in subjects with knee osteoarthritis. Methods: Simple random sampling was used to divide 30 subjects aged 50 and 70 years who met the inclusion and exclusion criteria into two groups (n=15). Group A received sensory-motor training, while Group B received impairment-based training. Before the treatment, the subjects walked for 10 minutes to warm up. For three weeks, each group was treated three times per week. Pre-test; post-test outcomes are noted, the visual analog scale (VAS) was used to assess pain, and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) was used to assess physical function. Results: Comparing the post-test pain (VAS) scores between groups showed that the mean±SD of posttest pain (VAS) score in the sensory-motor training group was 2.707±1.01. The mean±SD in the impairment-based training group was almost the same, at 2.29±1.13. It was statistically significant at the 5% level. Similarly, the mean±SD of the posttest function (WOMAC) score in the sensory-motor training group was 16.55±6.92. Conclusion: Sensory-motor training is superior to impairment-based training on pain and physical function in subjects with knee osteoarthritis.

DISSENTING OPINION OF A JUDGE AS A MANIFESTATION OF THE DISINTEGRATION OF THE JUDICIARY BOARD
Authors: Лыков Дмитрий Андреевич , Дикарев Илья Степанович
Published: August 2022

The criminal procedural legislation provides for the right of a judge who becomes the minority while decision-making to express a dissenting opinion in writing. This right is considered by the theory of criminal proceedings as a guarantee of the principle of freedom to evaluate evidence. It is widely believed that a dissenting opinion is a condition for a judge to sign a verdict with which he disagrees. These established positions are controversial and in need of rethinking. Purpose: to assess the appropriateness of maintaining the institution of dissenting opinion in the context of legal relations between the court and other participants in criminal proceedings, on the one hand, and within the judicial board, on the other. Methods: the methodological basis of the study is the dialectical method; in addition, general scientific methods of analysis, synthesis and a systematic approach are used, as well as special legal methods: historical-legal, legal interpretation and logical-legal. Results: the study concludes that a dissenting opinion does not have any legal effect; its sole appointment is to separate the judge’s position from that of the entire court. Such an individualization of the judge's position separates the judge from the composition of the court to which he is a member, thereby destroying the unity of the judiciary, undermines the trust of the participants in criminal proceedings and society in justice. Moreover, the existence of a dissenting opinion in the case raises groundless doubts about the legality, reasonableness and fairness of the judicial act. In this connection, it is concluded that it is expedient to eliminate the institution of judge’s dissenting opinion.

Published: August 2022

The legislation of the Russian Empire, which regulated the right of judicial representation for all subjects, including women, developed at the turn of the XIX–XX centuries in accordance with the principles that were characteristic of that time. The issue of the right of women’s judicial representation came to the fore in the context of women’s access to higher legal education. However, due to the outbreak of the First World War and rapidly developing revolutionary events, it was possible to solve it only after the February bourgeois-democratic revolution. Purpose: to study the reaction of the scientific community and legal practitioners in Russia to changes in the legislation in this matter, in their opinion, which were detrimental to the rights of women and were «lessons of legality», and to analyze the specifics of solving the problem of women’s advocacy at the turn of the XIX-XX centuries. Methods: historical, description, dialectical logic, formal-legal, interpretation of legal norms, system-functional methods are applied. Results: the study concludes that all the efforts of the scientific community and legal practitioners were not in vain: as a result of the events that were associated with the beginning of the February bourgeois-democratic revolution in Russia, Article 4061 of the Establishment of court orders, which infringed on the right of women to litigate in courts was finally abolished.

The management of the Golkar Party in Aceh Besar Regency is committed to carrying out its role since recruitment is carried out in a closed manner as a means of regeneration and openly by providing the widest opportunity for the people to participate in political activities in order to improve the performance of legislative members which are currently considered inadequate. This is due to the low quality of human resources as a result of the weak mechanism for recruiting legislative candidates. The formulation of the problem in this researchwhat is the role of the Golkar Party administrators in Aceh Besar Regency in the 2019 legislative elections andWhat are the factors that hinder and encourage? for the Golkar Party administrators in carrying out their roles. This study uses a qualitative approach to get an overview of the role of the board of directorsGolkar Party in the 2019 legislative elections. The conclusion of the study shows thatthe board plays a role in recruitment through a closed screening of cadres and also openly to the community, then party administrators have a role in determining them to be legislative candidates. Furthermore, there is socialization that is from the party and there is also socialization by the legislative candidates. Constraintfor the Golkar Party administrators in carrying out their rolesconsists of internal constraints including funding and competition between candidates. Meanwhile, external constraints consist of competition between political parties and figures in the eyes of the community. The competition between political parties is common to Golkar, considering that it is a fighting party and even a winning party, but in the context of Aceh, it is a little different because there are local parties that are still the desire of the community. Then to face the competition, the motivating factor for the Golkar Party is to sacrifice some of its cadres and choose other figures who are considered better in the eyes of the community. It was all done to increase the party's electability.

Entre los residuos de la construcción que se producen en el país de Panamá se encuentra el hormigón, este material de la construcción que se utiliza en cualquier obra civil y el máximo responsable de la generación de datos en las construcciones y demoliciones de infraestructuras. Una de las posibles soluciones para bajar la cantidad de residuos de construcción y demolición en el país es el reciclado de concreto, para el uso en la construcción de elementos que no son responsabilidad de la carga o para producir nuevos productos. Se puede reutilizar el hormigón por medio de la trituración de un concreto existente y así incorporarlo para hacer mezclas nuevas de hormigón. El estudio busca demostrar, mediante la aplicación de las normas ASTM (Asociación Americana de Ensayo de Materiales) y los resultados de las pruebas de resistencia, que es posible hacer que se pueda utilizar en la construcción para las estructuras como las aceras y para adicionarlo a mezclas de concreto.

Los lodos orgánicos son el desecho sólido de las plantas de tratamiento de aguas residuales (PTAR). Actualmente, la PTAR de la ciudad de Panamá vierte al relleno sanitario Cerro Patacón 70 Tm/día de este. La carbonización de estos residuos en un gasificador de flujo ascendente se presenta como una alternativa para el aprovechamiento de estos en aplicaciones agrícolas. El biocarbón obtenido podría mejorar las características fisicoquímicas del suelo, ya que en el país 27 % de estos se encuentran degradados. Este estudio tiene como objetivo evaluar la carbonización de lodos orgánicos para su utilización en los suelos. Se pudo identificar que los lodos orgánicos solos no se lograron carbonizar, debido al poco material volátil que poseen. Se observó que al agregar 25 % de cascarilla de arroz, se aportó materia volátil para que las reacciones exotérmicas liberaran suficiente energía para la carbonización de los residuos orgánicos. El proceso de carbonización presentó una productividad promedio de 46.83 wt%. La caracterización mostró el aumento de nutrientes esenciales en el carbón, como calcio, fósforo y potasio. Sin embargo, el nitrógeno, carbono y materia orgánica disminuyeron. Los resultados de este estudio demostraron que una mezcla carbonizada de lodos orgánicos y cascarilla de arroz podría contribuir a mejorar las propiedades del suelo.

Panamá es productor de cacao de gran fineza y calidad. En la región de Bocas del Toro se produce aproximadamente el 98% del cacao del país, y este con características de cultivos orgánico certificado. Actualmente en el país escasean los jabones a base de cacao orgánico, dato que permite hacer un análisis muestral, específicamente en el distrito de David. De este análisis, se conoció que el 93 % de los encuestados están dispuestos a usar un jabón a base de cacao orgánico con cascarilla. Se establece como objetivo de investigación, elaborar un jabón de cacao orgánico. Se desarrollaron dos prototipos, uno a base de glicerina y el otro a base de hidróxido de sodio. Entre las cualidades que deben tener los jabones para el cuidado personal, estos deben poseer un pH neutro de 7 y según el Codex Alimentario, la cantidad de materia insoluble en etanol no debe ser mayor a 0,2 g. Se realizaron pruebas de pH a cinco jabones, se obtuvieron medidas de pH por encima de 10 en todos los jabones. También se analizaron pruebas de sólidos insolubles en ETOH. Uno de los prototipos desarrollados en esta investigación obtuvo medidas por debajo de 0.2 g, siendo este un punto positivo a la investigación. En cuanto a precio, se manejan presupuestos altos, lo cual indica que hay que estructurar los procesos de obtención de la materia prima, que permitan disminuir el costo de producción y ofrecer un precio de venta competitivo en el mercado.

Se investigó la efectividad del método mamá canguro para el manejo del dolor no quirúrgico en un grupo de recién nacidos del servicio de neonatología de un hospital de la localidad. Se utilizó un enfoque cuantitativo, experimental. La muestra de 16 neonatos (8 del grupo experimental a quienes se le aplicó el método mamá canguro para manejar el dolor no quirúrgico y, 8 neonatos del grupo control a quienes se le realizaron los procedimientos terapéuticos de rutina sin estrategias de control del dolor, tal como lo establece el protocolo de atención del servicio); fue captada de forma intencional. Se aplicó el instrumento validado de Susan Givens, que mide 6 parámetros conductuales y 5 de las constantes vitales asociadas con manifestaciones del dolor, éste se aplicó antes y después del procedimiento terapéutico doloroso para comparar estos dos momentos en cada neonato de la muestra y entre ambos grupos; es decir medir el dolor del grupo control y el experimental. La prueba de chi cuadrado se utilizó para probar la relación entre el control del dolor y la aplicación del método mamá canguro. Los procedimientos médicos cuya intensidad del dolor fue medida, fueron punciones de talón y administración de vacunas. Resultados: en todas las valoraciones conductuales, el grupo intervenido evidenció tolerar mejor el dolor con respecto al grupo control, resaltando que ambos grupos partieron con puntajes equivalentes a un estado “sin dolor” según la escala aplicada (1.12 y 1.63 para el grupo intervenido y el grupo control respectivamente). Posterior al procedimiento médico doloroso, el grupo intervenido alcanza puntaje global de 7.12 que equivale a “dolor moderado”; en tanto el grupo control promedia su puntaje en 10.5 que equivale a “dolor intenso”. Todas las valoraciones conductuales y de las constantes vitales, demuestran una alta efectividad del método madre canguro para controlar el dolor no quirúrgico en el recién nacido. La prueba de chi-cuadrado con significación asintótica bilateral de 0.01, acepta que existe una relación significativa entre la intensidad del dolor y el uso del método madre canguro para controlarlo.

La salud estructural de los puentes juega un papel fundamental en el desarrollo urbano de cualquier ciudad. Para asegurar su buen mantenimiento y vida útil, es necesario realizar monitoreo de estos, sin embargo, este trabajo tiende a volverse tedioso, ya que se debe pasar largas jornadas bajo las condiciones ambientales presentes en el puente, además de recurrir a la utilización de una fuente de alimentación ro renovable para hacer uso del sistema. A lo largo de este documento, se presenta un estudio sobre la factibilidad de un sistema generador de energía por las vibraciones naturales del puente, a través del uso de materiales piezoeléctricos, que funcionaría como una opción viable para la alimentación del sistema de monitoreo, volviéndolo autosuficiente, permitiendo así que este permanezca en el puente de forma semi permanente, sin ningún problema, reduciendo de esta manera el uso de personal de trabajo para el monitoreo y anulando el uso de energías no renovables para la alimentación del sistema, de forma permanente.

Published: August 2022

The metal polymers based on mono- and heteroligand β-diketonate complexes of Yb(III) with 2,7-dimethyl-octen-1-dione-3,5, 2,6-dimethyl-heptene-1-dione-3, 5 and with phenanthroline was synthesized. It has been defined that the coordination environment of the central ion remains unchanged during radical polymerization. The shape and position of the bands in the electronic absorption spectra are similar to the corresponding monomeric β-diketonate metal complexes, and slight shifts indicate deformation of the elementary unit of the metal polymer during the formation of the polymer chain. It is shown that the polymerization process lead to an increasing in the thermal stability of polymer complexes in comparison with monomeric analogues. An increase in the emission of metal polymers in comparison with monomeric complexes was established by the method of luminescent spectroscopy, which is due to energy, steric, and structural-mechanical factors.

The pathogen transmittingAedes albopictusmosquito is spreading rapidly in Europe, putting millions of humans and animals at risk. This species is well-established in Albania since its first detection in 1979. The sterile insect technique (SIT) is increasingly gaining momentum worldwide as a component of area-wide-integrated pest management. However, estimating how the sterile males will perform in the field and the size of target populations is crucial for better decision-making, designing and elaborating appropriate SIT pilot trials, and subsequent large-scale release strategies. A mark-release-recapture (MRR) experiment was carried out in Albania within a highly urbanized area in the city of Tirana. The radio-sterilized adults ofAe. albopictusAlbania strain males were transported by plane from Centro Agricoltura Ambiente (CAA) mass-production facility (Bologna, Italy), where they were reared. In Albania, sterile males were sugar-fed, marked with fluorescent powder, and released. The aim of this study was to estimate, under field conditions, their dispersal capacity, probability of daily survival and competitiveness, and the size of the target population. In addition, two adult mosquito collection methods were also evaluated: BG-Sentinel traps baited with BG-Lure and CO2,(BGS) versus human landing catch (HLC). The overall recapture rates did not differ significantly between the two methods (2.36% and 1.57% of the total male released were recaptured respectively by BGS and HLC), suggesting a similar trapping efficiency under these conditions.Sterile males traveled a mean distance of 93.85 ± 42.58 m and dispersed up to 258 m. Moreover, they were observed living in the field up to 15 days after release with an average life expectancy of 4.26 ± 0.80 days. Whether mosquitoes were marked with green, blue, yellow, or pink, released at 3.00 p.m. or 6.00 p.m., there was no significant difference in the recapture, dispersal, and survival rates in the field. The Fried competitiveness index was estimated at 0.28. This mark-release-recapture study provided important data for better decision-making and planning before moving to pilot SIT trials in Albania. Moreover, it also showed that both BG-traps and HLC were successful in monitoring adult mosquitoes and provided similar estimations of the main entomological parameters needed.

Purpose: To detect previously undetectable changes in vessel density and structural thickness, the two biomechanics-related parameters reflecting hemodynamics and tensile strength, respectively, in the peripheral and central fundi of nonpathological myopic eyes with an advanced ultrawide-field optical coherence tomography angiography (OCTA) system.

Methods: A cross-sectional observational clinical study was carried out by recruiting 155 eyes from 79 college students aged 18–28 years. The eyes were stratified into normal, low-myopia, medium-myopia, and high-myopia groups according to diopter. A newly developed OCTA system with scanning dimensions of 24 mm × 20 mm, acquisition speed of 400 kHz, and imaging range of 6 mm was used to examine the vessel densities of superficial vascular complex (SVC), deep vascular complex (DVC), choriocapillary (ChC), and choroidal vessel (ChV) layers, as well as the thicknesses of the inner retina, outer retina, and choroid in the nonpathological myopic eyes.

Results: The vessel densities in ChV at the temporal, inferotemporal, inferior, and inferonasal regions in the fundus periphery were significantly reduced in myopic subjects as compared to normal controls (all p < 0.05). The thicknesses of the inner retinal segments in most peripheral regions of the fundus became attenuated along with myopia severity (all p < 0.05). The thicknesses of the outer retinal segments were diminished at the superior and supranasal regions of the peripheral fundi of myopic subjects as compared to normal controls (all p < 0.05). At the central macular region, the decreased vessel densities of SVC and DVC were correlated with the attenuated thicknesses of inner retinal segments, respectively (all p < 0.05).

Conclusion: As revealed for the first time by the advanced ultrawide-field OCTA system, the two biomechanics-related parameters that include the densities of the choroidal vessels and thicknesses of the inner retina segments were significantly reduced in the periphery of nonpathological myopic fundi and the reductions were associated with myopia severity. At the central macular region, the newly developed device provides consistent results with the previous findings. Therefore, it is important to use the noninvasive, ultrawide-field OCTA with high resolution for early detection of fundus changes in subjects with nonpathological high myopia.

Temporal procedures of mutual alignment and synchronization in collaborative meaning-making activities in a dance rehearsal
Authors: Krug Maximilian
Published: August 2022

Synchrony is a members' interactional solution for dealing with multiple relevant interactional tasks simultaneously when working on two or more separate, perceptual, and equally relevant projects, e. g., when dancing while pointing out a feature of the ongoing dance. This paper focuses on moments in which participants engage in joint meaning-making to identify, negotiate, and implement displayed multimodal gestalts of the choreography. Three temporal procedures of mutual alignment and synchronization were identified through a conversation analytical approach in combination with marker-less motion tracking movement analysis of a dance rehearsal: delays, accelerations, and accentuations. The analyses revealed that synchrony requires constant coordination in order to establish, maintain, and dissolve alignment between participants and their multimodal resources.
Evolution of drainage patterns in active fold-thrust belts: A case study in the Qilian Mountains

Published: August 2022

The Qilian Mountains are a typical active fold-thrust belt. A series of large and elongated drainage basins are oriented almost parallel to the Mountain Chain. Conversely, on North flank of the Qilian Mountains, transverse rivers dominate the drainage network. However, the evolution of these drainage patterns is still poorly understood. Here, we first review the evolutionary history of the drainage pattern of major rivers in the Qilian Mountains. We find that early transverse-dominated river networks are progressively replaced by longitudinal-dominated rivers during mountain building. Because the incision rate of transverse rivers is defeated by the uplift rate of mountains, the transverse rivers would be diverted toward the fold tips and gradually lengthened. Then, we analyze the evolutionary trends of drainage networks using topographic metrics. We suggest that longitudinal rivers, especially the upper reach of longitudinal rivers, will be captured by transverse rivers. Our study shows that the evolution of drainage patterns in active fold-thrust belts has two stages: in the early stage, transverse rivers would be replaced by longitudinal rivers; in the later stage, the upper longitudinal rivers would be captured by transverse tributaries. Moreover, the evolution model of drainage patterns in active fold-thrust belts is validated by using the TopoToolbox Landscape Evolution Model (TTLEM). Tectonics and deformation impart a lasting impression on the planform pattern of drainage networks. However, the drainage network will show different patterns in various evolution stages, even with consistent tectonic conditions. The results of this study may help investigate the drainage network evolution process in other active fold-thrust belts.
Pressure prediction in deep-water pipeline considering formation of natural gas hydrate

Published: August 2022

Pressure in the deep-water pipeline is an important parameter that should be carefully predicted to control the natural gas transport in petroleum industry. However the present methods to predict pressure along the deep-water pipeline are complex and time-consuming. Some methods even ignore the formation of natural gas hydrate leading to the inaccurate pressure prediction. In this work, we proposed a model to predict the pressure along the deep-water pipeline considering the reduction of pipeline radius induced by the formation of natural gas hydrate. The model was validated by experimental data and was applied to the real deep-water pipeline in China. Results indicate that the decline of pressure in the pipeline is mainly caused by the reduction of pipeline radius due to the formation of natural gas hydrate compared with the flow resistance caused by viscous flow. The decline of pressure becomes faster against time with the 40% pressure loss at the fifth year of natural gas transport. This model enables to obtain the pressure values in the deep-water pipeline with high accuracy and good convenience.

Published: August 2022

Background

Medullary thyroid cancer (MTC) can only be cured by surgery, but the management of lateral lymph nodes is controversial, especially for patients with cN0+cN1a. To address this challenge, we developed a multivariate logistic regression model to predict lateral lymph node metastases (LNM).

Methods

We retrospectively collected clinical data from 124 consecutive MTC patients who underwent initial surgery at our institution. The data of 82 patients (from 2010 to 2018) and 42 patients (from January 2019 to November 2019) were used as the training set for building the model and as the test set for validating the model, respectively.

Results

In the training group, the multivariate analyses indicated that male and MTC patients with higher preoperative basal calcitonin levels were more likely to have lateral LNM (P = 0.007 and 0.005, respectively). Multifocal lesions and suspected lateral LNM in preoperative ultrasound (US) were independent risk factors (P = 0.032 and 0.002, respectively). The identified risk factors were incorporated into a multivariate logistic regression model to generate the nomogram, which showed good discrimination (C-index = 0.963, 95% confidence interval [CI]: 0.9286–0.9972). Our model was validated with an excellent result in the test set and even superior to the training set (C-index = 0.964, 95% CI: 0.9121–1.000).

Conclusion

Higher preoperative basal calcitonin level, male sex, multifocal lesions, and lateral lymph node involvement suspicion on US are risk factors for lateral LNM. Our model and nomogram will objectively and accurately predict lateral LNM in patients with MTC.

Published: August 2022

Aldosterone-producing adenoma is a rare cause of hypertension in children. Only a limited number of cases of aldosterone-producing adenomas with somatic KCNJ5 gene mutations have been described in children. Blacks are particularly more susceptible to developing long-standing cardiovascular effects of aldosterone-induced severe hypertension. Somatic CACNA1D gene mutations are particularly more prevalent in black males whereas KCNJ5 gene mutations are most frequently present in black females. We present here a novel somatic KCNJ5 p.I157S mutation in an aldosterone-producing adenoma from a 16-year-old black female whose severe drug-resistant hypertension significantly improved following unilateral adrenalectomy. Prompt diagnosis of aldosterone-producing adenoma and early identification of gene mutation would enable appropriate therapy and significantly reduce cardiovascular sequelae.
Scores of peripheral neuropathic pain predicting long-term mortality in patients with type 2 diabetes: A retrospective cohort study
Authors: Liau Yi-Ju , Lin Shu-Fan , Lee I-Te
Published: August 2022

Objectives

Diabetic peripheral neuropathic pain (DPNP) is a prevalent chronic complication in patients with diabetes. Using a questionnaire is helpful for DPNP screening in outpatients. In this retrospective cohort, we aimed to examine whether DPNP diagnosed based on scoring questionnaires could predict long-term mortality in outpatients with type 2 diabetes.

Methods

We enrolled 2318 patients who had joined the diabetes pay-for-performance program and completed the annual assessments, including both the identification pain questionnaire (ID pain) and Douleur Neuropathique en 4 questionnaire (DN4), between January 2013 and October 2013. Information on registered deaths was collected up to August 2019.

Results

There was high consistency in the scores between the ID pain and DN4 (r = 0.935, P < 0.001). During the median follow-up of 6.2 years (interquartile range: 5.9−6.4 years), 312 patients deceased. Patients with an ID pain score of ≥ 2 had a higher mortality risk than those with a score of < 2 (hazard ratio [HR] = 1.394, 95%CI: 1.090−1.782), and patients with a DN4 score of ≥ 4 had a higher mortality risk than those with a score of < 4 (HR = 1.668, 95% confidence interval [CI]: 1.211−2.297). Patients consistently diagnosed with DPNP by the ID pain and DN4 had a significantly higher mortality risk (HR = 1.713, 95% CI: 1.223−2.398, P = 0.002), but not those discrepantly diagnosed with DPNP (P = 0.107), as compared with those without DPNP.

Conclusions

Both the ID pain and DN4 for DPNP screening were predictive of long-term mortality in patients with type 2 diabetes. However, a discrepancy in the diagnosis of DPNP weakened the power of mortality prediction.
