Published: February 2022

BackgroundThe presence of microstructural white matter (WM) abnormalities in individuals with bipolar disorder (BD) has previously been reported. However, the interpretation of data is challenging because pharmacological treatment has a potential effect on WM integrity. To date, no study has compared the differences in WM structure among drug-naïve BD patients, drug-naïve major depression disorder (MDD) patients, and healthy controls (HC) using the visual evaluation method of diffusion tensor tractography (DTT).MethodsThis retrospective study included 12 drug-naïve patients with BD, 15 drug-naïve patients with MDD, and 27 age- and sex-matched HC individuals. Visual evaluation, fractional anisotropy (FA), and apparent diffusion coefficient (ADC) were analysed in the anterior thalamic radiation (ATR) as a tract of interest using the optimal follow-up truncation threshold. They were also analysed in the cingulate fasciculus, superior longitudinal fasciculus, inferior longitudinal fasciculus, inferior fronto-occipital fasciculus, uncinate fasciculus, and fornix.ResultsNo significant differences were found in the FA or ADC of any tract. However, visual evaluation revealed poorer depiction of ATR in patients with BD than in patients with MDD and HC individuals (p = 0.004). Our post-hoc analysis showed a significant difference between BD and HC patients (p = 0.018).ConclusionsThe visual evaluation method of DTT revealed poor depiction of ATR in patients with BD compared with HC individuals and MDD patients, suggesting microstructural WM abnormalities of ATR in BD.

Late-life depression (LLD) is an important public health problem among the aging population. Recent studies found that mindfulness-based cognitive therapy (MBCT) can effectively alleviate depressive symptoms in major depressive disorder. The present study explored the clinical effect and potential neuroimaging mechanism of MBCT in the treatment of LLD. We enrolled 60 participants with LLD in an 8-week, randomized, controlled trial (ChiCTR1800017725). Patients were randomized to the treatment-as-usual (TAU) group or a MBCT+TAU group. The Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA) were used to evaluate symptoms. Magnetic resonance imaging (MRI) was used to measure changes in resting-state functional connectivity and structural connectivity. We also measured the relationship between changes in brain connectivity and improvements in clinical symptoms. HAMD total scores in the MBCT+TAU group were significantly lower than in the TAU group after 8 weeks of treatment (p &lt; 0.001) and at the end of the 3-month follow-up (p &lt; 0.001). The increase in functional connections between the amygdala and middle frontal gyrus (MFG) correlated with decreases in HAMA and HAMD scores in the MBCT+TAU group. Diffusion tensor imaging analyses showed that fractional anisotropy of the MFG-amygdala significantly increased in the MBCT+TAU group after 8-week treatment compared with the TAU group. Our study suggested that MBCT improves depression and anxiety symptoms that are associated with LLD. MBCT strengthened functional and structural connections between the amygdala and MFG, and this increase in communication correlated with improvements in clinical symptoms.Randomized Controlled Trial; Follow-Up Study; fMRI; Brain Connectivity

BackgroundA needle stick injury is a serious occupational health hazard in health care settings. Health care workers are at risk of bloodborne diseases and the psychological consequences of these injuries. This study aims to estimate the incidence of needle stick injuries among healthcare workers during the previous 12 months and to assess their knowledge, attitude, and practice toward these injuries.MethodsThis cross-sectional study was conducted from 1st August 2019 till 15th February 2020, and included 786 healthcare workers in Abha city, Saudi Arabia. A structured questionnaire was used to collect the data.ResultsThe incidence of needle stick injury among healthcare workers during the previous 12 months was (91/786) 11.57%. Nurses, females, and Saudis reported most needle stick injuries. More than half (52.7%) of the injuries went unreported. About 52.7% of needle stick injuries occurred during using sharp devices, and 42.9% of injuries happened in the patient room. The incidence of needle stick injury was significantly higher among those working at the secondary healthcare level (p= 0.003) and those practicing surgery (p&lt; 0.001). Out of 786 participants, 94.7% knew the definition of needle stick injury, and 81.0% were aware of the procedure and guidelines to follow on sustaining a needle stick injury. Only 61.2% recognized that the recap of the needle is not recommended. Almost half of the participants (47.1%) agreed, and 33.6% strongly agreed that needle stick injury is preventable. A majority of healthcare workers (89.1%) had been vaccinated against Hepatitis B. Nearly 27.5% of healthcare workers incorrectly practiced recapping the needles with two hands and 8.7% bent needles before disposal. Recapping the needles was statistically significantly higher among healthcare workers who had a history of needle stick injury (p= 0. 046).ConclusionNeedle stick injury and its under reporting among healthcare professionals is still a prevalent risk. Raising awareness among healthcare workers and improving the reporting systems for needle stick injuries to ensure more protection and early use of post-exposure prophylaxis is required. Implementation of safety precautions and safe injection practices and providing engineered safety devices may further reduce the risk.

Authors: Zhang Li , Xu Yanwen 
Published: February 2022

BackgroundTo compare incontinence rates and complications in patients receiving artificial urinary sphincter (AUS) with or without radiotherapy (RT).MethodsPubMed, Embase, ScienceDirect, CENTRAL, and Google Scholar databases were searched for studies comparing outcomes of AUS between patients with and without RT. Search limits were from 1st January 2002 to 15th September 2021.ResultsEighteen studies were included. Meta-analysis revealed statistically significant reduced odds of the absence of incontinence in the RT group (OR: 0.35 95% CI: 0.21, 0.59 I2 = 51% p &lt; 0.0001) as compared to the no-RT group. We also noted statistically significant increased risk of revision surgery in the RT group (OR: 1.74 95% CI: 1.16, 2.60 I2 = 73% p = 0.07). There was increased risk of infections (OR: 2.51 95% CI: 1.00, 6.29 I2 = 46% p = 0.05) and erosions (OR: 2.00 95% CI: 1.15, 3.45 I2 = 21% p = 0.01) in the RT group, but the difference was significant only for erosions. Meta-analysis revealed a statistically significant increased risk of explantation in patients with RT (OR: 3.00 95% CI: 1.16, 7.75 I2 = 68% p = 0.02) but there was no difference in the risk of urethral atrophy (OR: 1.18 95% CI: 0.47, 2.94 I2 = 46% p = 0.72) and mechanical failure (OR: 0.90 95% CI: 0.25, 3.27 I2 = 54% p = 0.87) between the two groups.ConclusionsOur meta-analysis of recent studies indicates that RT significantly reduces the odds of achieving complete continence after AUS placement. History of RT does not increase the risk urethral atrophy or mechanical failure in patients with AUS. However, the risk of revision surgery, erosions and explantations is significantly increased in patients with RT with a non-significant but increased tendency of infections.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/, identifier: NCT02612389.
Effect of Flux Rate Variation at Fixed V/III Ratio on Semi-Polar (112¯2) GaN: Crystal Quality and Surface Morphology Study

Published: February 2022

We report on the crystal improvement of semi-polar (112¯2) gallium nitride epitaxy layer on m-plane (101¯0) sapphire substrate by changing the flux rate at a fixed V/III ratio. The high-resolution X-ray diffraction (HR-XRD) analysis showed that lower flux rate enhanced the crystal quality of GaN epitaxy with the lowest FWHM values of 394 and 1173 arc seconds at [11¯23] and [11¯00] planes, respectively. In addition, Raman spectroscopy showed that flux rate did not affect the stress state of the GaN crystal. However, atomic force microscopy (AFM) micrograph depicted an anomalous trend where the lowest flux rate produces roughest surface with RMS roughness of 40.41 nm. Further analysis of AFM results on the undulation period length along [11¯23] and [11¯00] directions is carried out. It shows that as the growth rate decreases, the average undulation period along [11¯23] and [11¯00] directions increases from 2.59 µm and 1.90 µm to 3.52 µm and 3.52 µm, respectively. The mechanism for the surface roughening at the lower flux rate is then explained by using the adatom surface diffusion relation L ~ Dτ.

The impacts of ice-storms on forests have received growing attention in recent years. Although there is a wide agreement that ice-storms significantly affect forest structure and functions, how frequent ice-storms and subsequent salvage logging impact productivity of subtropical coniferous forests in the future still remains poorly understood. In this study, we used the Ecosystem Demography model, Version 2.2 (ED-2.2), to project the impact of salvage logging of ice-storm-damaged trees on the productivity of Cunninghamia lanceolata-dominated coniferous forest and C. lanceolata-dominated mixed coniferous and broadleaved forests. The results show that forest productivity recovery is delayed in coniferous forests when there is no shade-tolerant broadleaved species invasion after ice-storms, and C. lanceolata could continue to dominate the canopy in the mixed coniferous and broadleaved forests under high-frequency ice-storms and subsequent salvage logging. The resistance and resilience of the mixed coniferous and broadleaved forests to high-frequency ice-storms and subsequent salvage logging were stronger compared to coniferous forests. Although conifers could continue to dominate the canopy under shade-tolerant broadleaved species invasion, we could not rule out the possibility of a future forest community dominated by shade-tolerant broadleaf trees because there were few coniferous saplings and shade-tolerant broadleaf species dominated the understory. Our results highlight that post-disaster forest management should be continued after high-frequency ice-storms and subsequent salvage logging in C. lanceolata forests to prevent possible shade-tolerant, late successional broadleaf trees from dominating the canopy in the future.

Приведены результаты расчетов циркуляционной установки для преобразования Q–H-характеристик лопастного насоса с отводом полезного расхода жидкости перед гидроструйным насосом. Получены математические зависимости, адекватно описывающие процесс работы циркуляционной установки для преобразования Q–H-характеристик лопастного насоса. Теоретически обосновано и экспериментально доказано, что замена высоконапорного гидроструйного насоса в циркуляционной установке двумя последовательно работающими средненапорными гидроструйными насосами позволяет при снижении гидравлического КПД циркуляционной установки с 42 до 33% и незначительном уменьшении полезного расхода Qнобеспечить устойчивое эжектирование воздуха из атмосферы и надежную работу напорного флотатора. Предложенная технологическая схема напорной флотации, предусматривающая использование циркуляционной установки для преобразования Q–H-характеристик лопастного насоса с двумя последовательно работающими средненапорными гидроструйными насосами, позволяет отказаться от использования дорогостоящего компрессора и заменить высоконапорный лопастной насос насосом с более низким рабочим давлением и меньшей стоимостью.
The results of calculating a circulation unit for converting the Q–H-characteristics of an impeller pump with the withdrawal of the useful fluid flow upstream the waterjet pump are presented. Mathematical dependencies are obtained that adequately describe the process of the operation of the circulation unit for the conversion of the Q–H-characteristics of an impeller pump. It has been theoretically substantiated and experimentally proved that replacing a high-pressure waterjet pump in the circulation unit with two sequentially operating medium-pressure waterjet pumps ensures the sustainable atmosphere air ejection and reliable operation of the pressure flotation unit, provided the hydraulic efficiency of the circulating unit is reduced from 42 to 33% and the useful flow rate Qн decreases slightly. The proposed process flow scheme of pressure flotation that involves the use of a circulation unit to convert the Q–H-characteristics of an impeller pump with two medium-pressure waterjet pumps operating in series, provides for abandoning the use of an expensive compressor and replacing a high-pressure impeller pump with a cheaper pump with lower operating pressure.

Одним из важнейших аспектов разрабатываемых в настоящее время технологий является то, что они должны быть безотходными либо малоотходными. При производстве синтетического гипса из осадков коагуляции природных вод и отходов серной кислоты образуется кислый фильтрат, который по своему составу содержит соли Mg, Na, Ca и Fe. Предложена и проработана возможность использования фильтрата с высоким содержанием железа для получения магнитных сорбентов при удалении нефтепродуктов из водных сред, а также для получения фотокаталитических материалов при деструкции растворенных органических веществ. Исследование показало, что магнитные сорбенты обладают нефтеемкостью до 2 г/г. Полученные фотокаталитические материалы обладают также высокой эффективностью фотодеструкции красителя (кислотного телона синего) на уровне 80% при времени обработки 60 минут.
One of the most important aspects of the technologies currently being developed is that they must be non-waste or low-waste technologies. In the process of producing synthetic gypsum from natural water coagulation sludge and sulfuric acid waste, acidic filtrate is formed that contains salts of Mg, Na, Ca and Fe. Possible using the filtrate with a high iron concentration in the preparation of magnetic sorbents for removing oil products from aqueous environment, as well as for the preparation of photocatalytic materials in the process of the destruction of dissolved organic substances, has been proposed and developed. The study showed that magnetic sorbents have an oil capacity of up to 2 g/g. The resulting photocatalytic materials also showed a high photodegradation efficiency of the dye (acidic telon blue) at the level of 80% at 60 minutes treatment time.

Abstract
With the construction of the energy internet, the demand for various sensing devices is increasing. Most of sensing devices need power source which limits their application in the wide spread distributed nodes of sensor network. Therefore, there is an urgent need to develop passive sensing devices which is more intelligent and convenient. This paper studies the magnetoelectric effect of layered magnetoelectric composites. Firstly, the physical process is analyzed by using the finite element method. Secondly, magnetoelectric response of the eddy current in the Cu-PZT layered composite material is investigated. Finally, the voltage variations of circular and rectangular samples are compared. It can be seen from the results that under the action of the eddy current, there is a u-shaped curve relationship between the induced voltage and the magnetic field. The energy conversion of metal-piezoelectric composite material without power source provides an effective path for developing passive magnetic sensor.
