Correlation between suicidal ideation and emotional memory in adolescents with depressive disorder
Authors: Hu Shuwen , Mo Daming , Guo Pengfei , Zheng Hongyu , Jiang Xiaolu , Zhong Hui 
Published: March 2022

AbstractThis study explored the differences in emotional memory between adolescents with and without suicidal ideation. Fifty adolescents with depression and suicidal ideation, 36 with depression but no suicidal ideation, and 41 healthy controls rated the emotional valence of positive, neutral, and negative pictures. Then, the recognition of the images was evaluated 72 h later. Adolescents with suicidal ideation reported more negative emotional valence scores for positive and neutral pictures and were significantly less likely to recognize negative pictures than were those without suicidal ideation. The performance of adolescents with suicidal ideation on the negative picture recognition test was closely related to anxiety, depression severity, and intensity of suicidal ideation. The negative bias toward neutral stimuli and cognitive impairment may be important risk factors for adolescents with suicidal ideation. Improving emotional memory via targeted management approaches may help young people with suicidal ideation.
How electrons Coulomb repulsion changes graphene band structure
Authors: Moradian Rostam , Rabibeigi Poorya 
Published: March 2022

AbstractBase on effective medium theory we introduce a multi sites method for calculation of realistic energy bands of strongly correlated systems. We found due to approximated self energy, the density of states that obtained directly by calculated local Green function does not reflects system energy bands truly. By using this method we investigated how electrons repulsion renormalizes graphene bands. Graphene realistic bands calculated in both the dynamical mean field theory (DMFT) and four sites beyond super cell approximation for different repulsions. Our calculated interacting graphene bands illustrate a semi metal to a Mott insulator anti ferromagnetic phase transition at repulsions $$u = 2.2 t$$

u
=
2.2
t

and $$u = 0.6 t$$

u
=
0.6
t

for DMFT and four sites beyond super cell approximation respectively. These values are much less than finite size quantum Monte Carlo calculation prediction. We showed that the graphene bands are very sensitive to electrons repulsions and this phase transition happens at low repulsions in comparison to graphene band width.
Neighborhood‐based distributed robust unknown input observer for fault estimation in nonlinear networked systems
Authors: Rahimi Farshad , Ahmadpour Shirin 
Published: March 2022

AbstractIn this paper, a robust distributed fault estimation is addressed for a class of nonlinear networked systems with actuator faults where influences from process disturbances are minimized. In real‐time monitoring systems, a substantial challenge is to find out the size and the shape of the occurred faults, and consequently, it is significantly more difficult in multi‐agent systems. To consider this concern, in this paper, a distributed fault estimation approach has been proposed for multi‐agent systems such that each agent employs an augmented system owing to a designated communication graph for estimating the fault and states both in this agent and in its neighbors. Meanwhile, each agent is equipped with an unknown input observer (UIO) to decouple the partial disturbances of the process as much as possible and to reduce the disturbances that cannot be decoupled. In the form of linear matrix inequalities (LMIs), sufficient conditions are provided to guarantee stability and to obtain the parameter matrices of the introduced observer. Finally, two numerical examples are provided to verify the performance of the introduced fault estimation scheme.

AbstractWith the increasing development of integrated energy systems and the continuous promotion of integrated demand response (IDR) research, residential users with a large amount of demand response resources are drawing more and more widespread attention. In order to fully exploit the IDR potential of residential users and analyse the influence of user comfort and consumer psychology (UCCP) on IDR, the optimised operation study of load aggregator (LA) based on UCCP‐IDR model is proposed. Firstly, a self‐organising map algorithm for clustering is introduced, from which various types of users with differentiated consumption psychology are obtained. Secondly, user comfort and consumption psychology are taken into account to establish a user curtailable, shiftable and transformable load model. Thirdly, the user IDR optimisation model is established based on the load model considering the user response uncertainty. Finally, based on the optimisation strategy of user IDR, the total energy demand of LA is obtained, and thus the optimal operation model of LA equipment is established. The analysis shows that the proposed strategy can provide a more reliable and targeted integrated demand response strategy for residential users, and achieve a win–win situation for both LA and residential users.
Optimal coordination of unbalanced power distribution systems with integrated photovoltaic systems and semi‐fast electric vehicles charging stations
Authors: Alabri Waleed , Jayaweera Dilan 
Published: March 2022

AbstractIncreased integration of photovoltaics (PVs) systems and charging stations for electric vehicles (EVs) has led to a substantial increase in the level of voltage unbalance beyond the acceptable limit. Ordinary voltage regulation devices such as on‐load tap changers (OLTCs) and distribution static synchronous compensator (DSTATCOM) are sometimes incapable of adequately addressing this issue without proper coordination with PVs and EVs. This paper presents a novel real‐time optimal coordination scheme to determine the tap position of OLTC, the amount of reactive power to be exchanged by DSTATCOM and a PV inverter, and the phase connection of EVs. The proposed scheme aims to maintain the voltage magnitude and voltage unbalance within the statutory limit while minimising the power losses in an active unbalanced power distribution system. Advanced and hybrid particle swarm optimisation (AHPSO) algorithm is also developed to solve the optimisation problem, and its robustness in comparison with other techniques is verified. The impact of uncoordinated voltage control and proposed control on voltage unbalance and power losses are investigated. Time‐series simulations confirm the significance and scalability of the developed coordination control scheme on IEEE 37‐node and IEEE 123‐node test feeders with real data and different PV penetration levels.
A global view of shocked plasma in the supernova remnant Puppis A provided by SRG/eROSITA
Authors: Mayer Martin G. F. , Becker Werner , Predehl Peter , Sasaki Manami , Freyberg Michael 
Published: March 2022

Context. Puppis A is a medium-age supernova remnant (SNR), which is visible as a very bright extended X-ray source. While numerous studies have investigated individual features of the SNR, at this time, no comprehensive study of the entirety of its X-ray emission exists.
Aims. Using field-scan data acquired by the SRG/eROSITA telescope during its calibration and performance verification phase, we aim to investigate the physical conditions of shocked plasma and the distribution of elements throughout Puppis A. In doing so, we take advantage of the uniform target coverage, excellent statistics, and decent spatial and spectral resolution of our data set.
Methods. Using broad- and narrow-band imaging, we investigate the large-scale distribution of absorption and the plasma temperature as well as that of typical emission lines. This approach is complemented by a spatially resolved spectral analysis of the shocked plasma in Puppis A, for which we divided the SNR into around 700 distinct regions, resulting in maps of key physical quantities over its extent.
Results. We find a strong peak of foreground absorption in the southwest quadrant, which in conjunction with high temperatures at the northeast rim creates the well-known strip of hard emission crossing Puppis A. Furthermore, using the observed distribution of ionization ages, we attempt to reconstruct the age of the shock in the individual regions. We find a rather recent shock interaction for the prominent northeast filament and ejecta knot, as well as for the outer edge of the bright eastern knot. Finally, elemental abundance maps reveal only a single clear enhancement of the plasma with ejecta material, consistent with a previously identified region, and no obvious ejecta enrichment in the remainder of the SNR. Within this region, we confirm the spatial separation of silicon-rich ejecta from those dominated by lighter elements. The apparent elemental composition of this ejecta-rich region would imply an unrealistically large silicon-to-oxygen ratio when compared to the integrated yield of a core-collapse supernova. In reality, both the observed ejecta composition and their apparent distribution may be biased by the unknown location and strength of the reverse shock.
Spatially resolved mass–metallicity relation at z  ∼  0.26 from the MUSE-Wide Survey
Authors: Yao Yao , Chen Guangwen , Liu Haiyang , Chen Xinkai , Lin Zesen , Zhang Hong-Xin , Gao Yulong , Kong Xu 
Published: March 2022

Aims. Galaxies in the local universe have a spatially resolved star-forming main sequence (rSFMS) and mass–metallicity relation (rMZR). We know that the global mass–metallicity relation (MZR) results from the integral of the rMZR, and it evolves with redshift. However, the evolution of the rMZR with redshift is still unclear because the spatial resolution and signal-to-noise ratio are low. Currently, too few observations beyond the local universe are available, and only simulations can reproduce the evolution of the rMZR with redshift.
Methods. We selected ten emission-line galaxies with an average redshift of z ∼ 0.26 from the MUSE-Wide DR1. We obtained the spatially resolved star formation rate (SFR) and metallicity from integral field spectroscopy (IFS), as well as the stellar mass surface density from 3D-HST photometry. We derived the rSFMS and rMZR at z ∼ 0.26 and compared them with those of local galaxies.
Results. We find that the rSFMS of galaxies at z ∼ 0.26 has a slope of ∼0.771. The rMZR exists at z ∼ 0.26, showing a similar shape to that of the local universe, but a lower average metallicity that is about ∼0.11 dex lower than the local metallicity. In addition, we also study the spatially resolved fundamental metallicity relation (rFMR) of these galaxies. However, there is no obvious evidence that an rFMR exists at z ∼ 0.26, and it is not an extension of rMZR at a high SFR.
Conclusions. Similar to their global versions, the rSFMS and rMZR of galaxies also evolve with redshift. At fixed stellar mass, galaxies at higher redshift show a higher SFR and lower metallicity. These suggest that the evolution of the global galaxy properties with redshift may result from integrating the evolution of the spatially resolved galaxy properties.
Treatment of Children Trichobezoar a Retrospective Study of 11
Cases
Authors: HanBin Zhao , Chunjiang Yang , Yi Wang 
Published: March 2022

Abstract
Purpose The goal of this study to summarize the clinical features,
treatment and prognosis of children trichobezoar, and to guide the clinical
diagnosis and treatment.
Methods The clinical manifestations, auxiliary examination results,
diagnosis and treatment process and family relationship of 11 cases of children
with trichobezoar in our hospital were analyzed retrospectively.
Results 11 cases were female, 4 cases were divorced single parent family,
and 2 case was left behind child. Six patients were admitted to hospital with
sudden exacerbation of chronic abdominal pain, and four of them had recurrent
vomiting. Five patients were admitted to hospital with acute abdominal pain, and
3 of them had vomiting symptoms; The weight of 1 case was lower than
−2 SD, 4 cases were between −2 SD ~
−1 SD. 6 cases had palpable left upper abdominal mass with mild
tenderness, 1 case only had left upper abdominal tenderness, 4 cases had no
positive abdominal signs; The results of color Doppler ultrasonography in 8
children indicated the strong echo mass in the stomach, and 3 of them showed
that the hyperechoic group extended to duodenum through pylorus. 7 cases had a
tail end extending into the small intestine after removing the gastrolith during
the operation. Four cases were found with jejunal perforation, 2 cases were
treated with intestinal resection and anastomosis, and 2 cases were treated with
intestinal repair. All the children were improved and discharged after
operation.
Conclusion For single parent families or left behind children with a
history of chronic abdominal pain, vomiting and trichophilia, gastric hair
stones should be highly suspected. For large hair stones in the stomach, they
should be removed surgically. During the operation, the small intestine should
be explored routinely to prevent the missed diagnosis of small intestinal
perforation. Psychological guidance should be given to the children and their
parents to prevent recurrence.
Family Structure is Associated with Mental Health and Attention
Deficit (Hyperactivity) Disorders in Adolescents with Type 1
Diabetes
Authors: Baechle Christina , Stahl-Pehe Anna , Castillo Katty , Holl Reinhard W. , Rosenbauer Joachim 
Published: March 2022

Abstract
Objective To analyze the cross-sectional associations of family structure
with mental health and attention deficit (hyperactivity) disorders (AD(H)D) in
11- to 17-year-old adolescents with early-onset type 1 diabetes participating in
one of three baseline surveys as part of an ongoing cohort study.
Methods Parents (n=1,631) completed the Strengths and Difficulties
Questionnaire to screen for their child’s mental health and answered
questions about their child’s diagnosis of AD(H)D. Associations between
mental health or AD(H)D and family structure were analyzed using multivariable
logistic regression analyses adjusted for various personal and diabetes-related
variables.
Results Compared to adolescents living with both parents, adolescents
living with one parent and his/her partner had 2.35 (95%
confidence interval 1.32; 4.21) higher odds of abnormal screening result and
2.08 (1.09; 3.95) higher odds of a borderline screening result while adolescents
living with a single parent had 1.84 (1.07; 3.17)/1.08 (0.53; 2.21)
higher odds of abnormal/borderline screening results. The odds ratios
for diagnosed attention deficit (hyperactivity) disorder were 2.17 (0.98; 4.84)
for adolescents living with one parent and his/her partner and 1.27
(0.54; 3.01) for those living with a single parent vs. both parents.
Conclusions Our results indicate higher odds of mental health problems and
AD(H)D in adolescents with type 1 diabetes who do not live with both parents;
this finding was most pronounced in individuals living with one parent and
his/her partner vs. both parents. Longitudinal studies are needed to
verify our results and elucidate the underlying mechanisms.
Adjustment of Anti-Hyperglycaemic Agents During Bowel Preparation for
Colonoscopy in Patients with Diabetes
Authors: Müssig Karsten , Adamek Henning E. 
Published: March 2022

Abstract
Objective Due to the growing diabetes pandemic, the number of
colonoscopies performed in patients with diabetes is steadily rising. However,
recommendations on adjustments of anti-hyperglycaemic agents (AHG) during bowel
preparation for colonoscopy are limited.
Methods A total of nine articles were revealed on a PubMed search using
the search terms “diabetes” and “colonoscopy”,
“sigmoidoscopy”, “endoscopy”,
“endoscopic intervention”, “endoscopic invasive
diagnostics”, “endoscopic surgery”, or “diabetes
care in the hospital” and manual screening of the references of the
articles reporting on AHG adjustment during bowel preparation.
Results Regular glucose measurements and the opportunity to contact the
diabetes team were commonly advised. Recommendations also agreed that all oral
AHG and short-acting insulin should be omitted when patients are on clear
fluids. Recent studies suggest discontinuation of sodium-glucose cotransporter-2
(SGLT2) inhibitors even three days before the colonoscopy. In contrast,
recommendations differed regarding adjustment of basal insulin depending on
diabetes type and time point in relation to the intervention.
Conclusions While discontinuation of oral AHG and short-acting insulin
during bowel preparation for colonoscopy is generally accepted, recommendations
on the adaptation of basal insulin follow different approaches.

Published: March 2022

AbstractIt’s crucial to comprehend the impact of oxidative stress and pro-inflammatory cytokines in the gentamicin-induced kidney injury mechanism. Celecoxib was administered orally either before or after intraperitoneal therapy with gentamicin in mice. The serum levels of creatinine (SCr), blood urea nitrogen (BUN), IL-6, and TNF-α were measured by ELISA test, as well as the levels of the kidney tissue malondialdehyde (MDA), and glutathione (GSH) were also estimated spectrophotometrically. The renal expression of nuclear factor-κB (NF-κB), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and cyclooxygenase 2 (COX-2) mRNAs were evaluated by qPCR. Histopathological evaluation and Immunohistochemical examination of kidney NF-κB, IL-6, and COX-2 were also, performed. Celecoxib successfully prevented gentamicin-induced kidney damage as indicated by reducing blood BUN, SCr, and tissue MDA levels and increasing renal tissue GSH levels as well as lowering the blood IL-6 and TNF-α in comparison to mice received gentamicin. Furthermore, celecoxib has inhibited COX-2, NF-κB, IL-6, and TNF-α expression in the renal tissue. It is noteworthy that celecoxib therapy after gentamicin administration brought about substantially the same results as celecoxib treatment before gentamicin injection in mice. Our results showed the role of celecoxib as a therapeutic tool for gentamicin-induced nephrotoxicity as well as raised its beneficial prophylactic role in this medical challenge by attenuating oxidative stress and inflammation.
Cigarette Smoking Increases the Risk of Type 2 Diabetes Mellitus in
Patients with Non-Alcoholic Fatty Liver Disease: A Population-Based Cohort
Study
Authors: Liu Chan , Wu Yanqin , Duan Wenjuan , Xu Wenming 
Published: March 2022

Abstract
Objective Cigarette smoke and non-alcoholic fatty liver disease are risk
factors for type 2 diabetes mellitus. However, the impact of smoking on diabetes
risk among patients with non-alcoholic fatty liver disease remains unclear.
Methods This study included 15,464 Japanese individuals. We defined
non-alcoholic fatty liver disease based on abdominal ultrasound findings where
excess alcohol intake and other liver diseases were excluded. We used Cox
proportional regression analysis to identify risk factors for type 2 diabetes
onset.
Results During 16,446 person-years of follow-up, 223 of 2,714
non-alcoholic fatty liver disease patients developed type 2 diabetes; the
cumulative incidence rate of type 2 diabetes was 13.6 per 1,000 person-years.
The proportions of never, former, and current smokers (self-report) were
35.3%, 31.1%, and 33.6%, and 88.5%,
5.1%, and 6.4% in men and women, respectively. In a Cox
regression model adjusted for sex, age, body mass index, waist circumference,
alcohol intake, exercise, and alanine aminotransferase, aspartate
aminotransferase, gamma-glutamyl transferase, lipid profiles, and blood pressure
values, relative to never smokers, current smokers with non-alcoholic fatty
liver disease had an increased risk of type 2 diabetes (hazard
ratio=2.05; 95% confidence interval: 1.43–2.94). In
addition, former smoking affected the risk of type 2 diabetes; however, this
effect was not statistically significant.
Conclusions This longitudinal study showed that current smoking may act as
a “second hit” and increase the risk of type 2 diabetes in
patients with non-alcoholic fatty liver disease.
Bilateral En-Block Horseshoe Kidney Laparoscopic Nephrectomy
Authors: Fernandez Nicolas , Rickard Mandy , Escobar Rebeca , Farhat Walid 
Published: March 2022

AbstractHorseshoe kidney (HSK) has a prevalence of 1 in every 500 individuals. The management of patients with HSK is usually conservative, except in the presence of symptoms such as obstruction, stones, glomerulopathies, and tumors. In the following case report, we describe how a bilateral en-block transmesenteric laparoscopic nephrectomy in supine position was performed.A 5-year-old boy, with proximal hypospadias and early onset of chronic kidney disease due to focal segmental glomerulosclerosis on biopsy, underwent a genetic molecular evaluation that confirmed a pathogenic mutation at the WT-1 gene. Due to the increased risk of developing Wilms tumor, he underwent a bilateral transmesenteric nephrectomy.In a five-minute video, we describe how we performed an en-block transperitoneal and transmesenteric laparoscopic nephrectomy with special attention to patient positioning, including the feasibility of performing the dissection of the left renal hilum and isthmus with the patient in supine with no need for repositioning, and then moving to the dissection of the right renal hilum and completion of the procedure.The case herein reported enables us to describe the technical key-points to perform a bilateral en-block laparoscopic nephrectomy with shorter operative time and reduction of blood loss by preserving the entire specimen, without the need for an isthmus transection.
