BackgroundThe COVID-19 pandemic has had a significant impact on pediatric patients, increasing their vulnerability to psychological fragility. The aim of this study was to investigate the epidemiology and clinical spectrum of pediatric psychological fragility and suicide attempts in the emergency department (ED) before and after the onset of the COVID-19 outbreak.MethodsA total of 340 pediatric patients admitted to the ED for psychological fragility between 2019 and 2022 were retrospectively collated and categorized according to three periods: pre pandemic, pandemic, and post pandemic. Epidemiological and clinical information were analyzed and compared among the three groups. Moreover, patients with suicidal ideation or suicidal attempts and types of substance use disorders in children with suicidal attempts sent to the ED were analyzed.ResultsThe proportion of psychological fragility increased during the pandemic period (0.4%) and the post-pandemic period (0.8%) compared to that in the pre-pandemic period (0.28%). Suicide ideation was the highest before the pandemic period (0.04%), while suicidal attempts were the highest in the post pandemic period (0.42%). Significantly elevated trends in suicide attempts involving overdose and injury were observed among the three groups (p &lt; 0.05). Intensive care unit (ICU) admission rates increased significantly after the COVID-19 outbreak (p &lt; 0.05), and major depressive disorder was the most common psychological fragility in the ED in all three groups.ConclusionAn increase in the proportion of pediatric psychological fragility in the ED was noted in the post pandemic period than before or during the pandemic. With higher rates of ICU admissions and an increase in suicide attempts among children and adolescents during the pandemic compared to before or after the pandemic, it is of utmost importance to provide mental health support to this vulnerable population in order to prevent suicide attempts in the event of a new global outbreak of infectious diseases.

Published: October 2023

Objectives: To investigate changes in multimorbidity patterns among Spanish older adults.Methods: Data come from the Spanish National Health Survey (ENSE) for individuals aged 60–89 years (2006: n = 9,758; 2017: n = 8,535). Prevalence rates and relative risks of 20 chronic conditions are estimated for the multimorbidity (3+ chronic conditions) sample, along with observed-to-expected prevalence of three-way disease combinations. Principal component and cluster analyses identify multimorbidity patterns and track temporal changes.Results: Overall, multimorbidity remained stable [2006: 59.6% (95% CI: 58.7%–60.6%); 2017: 60.3% (CI: 59.3%–61.3%)], except at older ages. Women exhibited higher multimorbidity prevalence, but sex differences declined by five percentage points. Low-high education differences widened by three percentage points. In 2017 most individuals living with multimorbidity experienced hypertension (63.4%), osteoarthrosis (62.4%) and chronic back pain (55.9%). These chronic conditions also dominate the most common triadic combinations. Multimorbid men also saw increases in cholesterol and diabetes.Conclusion: Multimorbidity trends and the most common combination of diseases can help plan healthcare for an ageing population. Sex and socioeconomic differences pose additional public health challenges as women and deprived populations tend to have more health complexities.

Let R be a commutative ring with identity, and Z(R) be the set of zero-divisors of R. The weakly zero-divisor graph of R denoted by WΓ(R) is an undirected (simple) graph with vertex set Z(R)*, and two distinct vertices x and y are adjacent, if and only if there exist r∈ann(x) and s∈ann(y), such that rs=0. Importantly, it is worth noting that WΓ(R) contains the zero-divisor graph Γ(R) as a subgraph. It is known that graph theory applications play crucial roles in different areas one of which is chemical graph theory that deals with the applications of graph theory to solve molecular problems. Analyzing Zagreb indices in chemical graph theory provides numerical descriptors for molecular structures, aiding in property prediction and drug design. These indices find applications in QSAR modeling and chemical informatics, contributing to efficient compound screening and optimization. They are essential tools for advancing pharmaceutical and material science research. This research article focuses on the basic properties of the weakly zero-divisor graph of the ring Zp×Zt×Zs, denoted by WΓ(Zp×Zt×Zs), where p, t, and s are prime numbers that may not necessarily be distinct and greater than 2. Moreover, this study includes the examination of various indices and coindices such as the first and second Zagreb indices and coindices, as well as the first and second multiplicative Zagreb indices and coindices of WΓ(Zp×Zt×Zs).

β-Ga2O3 Schottky barrier diodes (SBDs) suffer from the electric field crowding and barrier height lowering effect, resulting in a low breakdown voltage (BV) and high reverse leakage current. Here, we developed β-Ga2O3 trench MOS-type Schottky barrier diodes (TMSBDs) on β-Ga2O3 single-crystal substrates with halide vapor phase epitaxial layers based on ultraviolet lithography and dry etching. The 1/C2−V plots are deflected at 2.24 V, which is caused by the complete depletion in the mesa region of the TMSBDs. A close-to-unity ideality factor of 1.02 and a low turn-on voltage of 0.72 V are obtained. This is due to the low interface trap density in the metal/semiconductor interface of TMSBDs, as confirmed by the current–voltage (I–V) hysteresis measurements. The specific on-resistance calculated with the actual Schottky contact area increases as the area ratio (AR) increases because of the current spreading phenomenon. Furthermore, the reverse leakage current of the TMSBDs is smaller and the BV is increased by 120 V compared with the regular SBD. This work paves the way for further improving the overall performance of β-Ga2O3 TMSBDs.

Three novel lipopeptides, PM130391 (1), PM130392 (2), and PM140293 (3) were obtained from cultures of Streptomyces tuirus PHM034 isolated from a marine sediment. Structural elucidation of the three compounds showed they belong to the nonribosomal peptides family, and they all contain an acylated alanine, three piperazic acids, a methylated glycine, and an N-hydroxylated alanine. The difference between the three compounds resides in the acyl chain bound to the alanine residue. All three compounds showed cytotoxic activity against human cancer cell lines. Genome sequence and bioinformatics analysis allowed the identification of the gene cluster responsible for the biosynthesis. Inactivation of a nonribosomal peptide synthase of this cluster abolished the biosynthesis of the three compounds, thus demonstrating the involvement of this cluster in the biosynthesis of these lipopeptides.

<p>Magnetic particle imaging (MPI) is a tracer imaging modality that detects superparamagnetic iron oxide nanoparticles (SPIOs), enabling sensitive, radiation-free imaging of cells and disease pathologies. The arbitrary waveform relaxometer (AWR) is an indispensable platform for developing magnetic nanoparticle tracers and evaluating tracer performance for magnetic particle imaging applications. One of the biggest challenges in arbitrary waveform excitation is direct feedthrough interference, which is usually six orders of magnitude larger than the signal from magnetic nanoparticles. This work will showcase hardware that suppresses this interference by an order of magnitude, increasing the dynamic range of the instrument and enabling mass-limited detection at full scale range. </p>

Published: October 2023

<p><code>Learning graph topology online with dynamic dependencies is a challenging problem. Most existing techniques usually assume the generative model to be a diffusion process instigated by a graph shift operator (</code><code><u>GSO</u></code><code>) and that a first-order method, such as </code><code><u>proximal</u></code><code> gradient or least-mean-square (</code><code><u>LMS</u></code><code>), are used to track the graph topology. However, they are often susceptible to noisy observations and does not perform well against second-order methods. This work proposed two forward-backward splitting algorithms called the </code><code><u>proximal</u></code><code> Newton-iterated extended </code><code><u>Kalman</u></code><code> filter (</code><code><u>PN</u></code><code>-</code><code><u>IEKF</u></code><code>) and </code><code><u>PN</u></code><code>-</code><code><u>IEKF</u></code><code>-vector </code><code><u>autoregressive</u></code><code> (</code><code><u>PN</u></code><code>-</code><code><u>IEKF</u></code><code>-VAR) algorithms to track non-causal and causal graph topology with dynamic dependencies, respectively. The proposed methods directly maximize the posterior probability distribution of the observable graph signal and graph matrix, which make our </code><code><u>PN</u></code><code>-</code><code><u>IEKF</u></code><code> framework to be more robust toward additive white Gaussian noise. The two methods can directly handle streaming data which process them as they become available. Effectiveness of the proposed methods can be further improved by including a $T$-squared detector in the tracking procedure, which helps to inject proper perturbation to the latent dynamic model such that the time-varying </code><code><u>nonstationary</u></code><code> graph can be reacquired faster amid abrupt changes in the underlying system. Results on relative error and normalized mean square error using synthetic data on </code><code><u>Erd</u></code><code>\fH{o}s-R\'enyi graph establish the efficacy of the proposed approach. Simulation results using data from the </code><code><u>Dataset</u></code><code> for Emotion Analysis Using EEG, Physiological and Video Signals (</code><code><u>DEAP</u></code><code>) and National Oceanic and Atmospheric Administration (</code><code><u>NOAA</u></code><code>) are encouraging. Computational and time complexity analysis of the proposed algorithm are given and compared with other algorithms.</code></p>

Land Surface Temperature (LST) adalah fenomena peningkatan suhu permukaan tanah yang lebih tinggi dibandingkan dengan suhu rata-rata di sekitarnya. Salah satu penyebab peningkatan LST adalah perubahan pola tutupan lahan. Penelitian ini dilakukan untuk mengetahui korelasi Normalized Difference Vegetation Index (NDVI) terhadap LST di Kabupaten Pasuruan. Penelitian ini dilakukan dengan cara mengunduh data dari citra satelit landsat pada website climate change tahun 2001 dan 2020, kemudian diolah menggunakan QGIS, dan dilakukan uji korelasi menggunakan microsoft excel. Kabupaten Pasuruan dipilih menjadi wilayah studi dalam penelitian ini, karena Kabupaten Pasuruan mengalami peningkatan suhu sebesar 2,050 Celcius dari tahun 2001 ke tahun 2022. Hasil yang diperoleh dari uji korelasi NDVI dan LST adalah -0,56 pada tahun 2001, yang berarti LST dan NDVI memiliki korelasi yang cukup kuat, namun korelasinya berhubungan terbalik. Hubungan terbalik menunjukkan jika kerapatan vegetasi yang rendah, maka suhu permukaan tanah akan naik dan berlaku sebaliknya. Korelasi pada tahun 2022 adalah -0,62 yang menunjukkan adanya peningkatan korelasi.

O edentulismo é um importante problema de saúde pública que acarreta inúmeras sequelas e reduz de modo significativo a qualidade de vida do paciente, tanto em termos funcionais quanto estéticos. Perdas dentárias do arco superior podem ser acompanhadas de atrofia da maxila, o que dificulta o processo de reabilitação, uma vez que impede a realização de procedimentos que.boa quantidade de massa óssea local. O presente estudo é uma revisão de literatura narrativa que visa descrever o uso da técnica all-on-4 na reabilitação de maxila atrófica em pacientes edêntulos. Assim, uma das abordagens para melhor reabilitação da maxila atrófica desdentada é a técnica all-on-4, procedimento cirúrgico que utiliza quatro implantes para ancoragem de prótese total do arco superior ou inferior. A angulação adequada dos implantes durante a técnica resulta em maior superfície para ancoragem da prótese fixa, que apresenta grande estabilidade e ótimo padrão estético. Trata-se de um procedimento minimamente invasivo e de custo relativamente reduzido que traz resultados satisfatórios na maioria dos casos de edentulismo com atrofia maxilar, com vantagens que incluem previsibilidade, menor tempo de execução do procedimento, redução do cantiléver posterior e elevada estabilidade biomecânica, além do custo reduzido e menor tempo de recuperação. Porém, trata-se de um método de difícil execução que requer bom planejamento e elaboração pré-cirúrgica, além de ser contraindicado em casos de discrasias hematológicas, diabetes, imunossupressão e doenças crônicas. Sua realização é feita em etapas que envolvem seleção do caso; análise da viabilidade de aplicação do protocolo; planejamento do caso; escolha dos locais dos implantes; colocação dos implantes e, por fim, a fase protética. Na grande maioria dos casos os sinais inflamatórios pós-procedimento são reduzidos e a sobrevida dos implantes é longa. Dessa forma, pode-se concluir que a reabilitação de edentulismo com maxila atrófica pela técnica all-on 4 é uma abordagem efetiva que permite que o paciente edêntulo possa recuperar tanto as funções de mastigação, deglutição e fala, como também melhorar o aspecto estético da face.

Бурая ржавчина, вызываемая паразитическим базидиальным грибом Puccinia recondita f.sp. tritici, одно из наиболее вредоносных заболеваний яровой мягкой пшеницы как в Казахстане, так и в мире. Развитие ржавчиных болезней может приводить к значительному снижению урожайности восприимчивых сортов пшеницы. Основной проблемой селекции пшеницы является потеря эффективности генов устойчивости, что обусловлено появлением новых вирулентных рас патогенов. В данной статье представлены результаты оценки устойчивости сортов яровой мягкой пшеницы на стадии проростков и взрослого растения, а также результаты скрининга Lr генов устойчивости с помощью молекулярных маркеров. В результате проведенных опытов было отобрано 9 образцов, демонстрирующих высокий уровень устойчивости к обоим расам P. recondita – MKT/Q и TJT/R на стадии проростков. В полевых условиях за два года испытаний было отобрано 6 сортов, проявивших высокий уровень устойчивости к возбудителю. Использование молекулярных маркеров позволило идентифицировать носителей эффективных Lr генов устойчивости. По результатам молекулярного скрининга определено 4 носителя гена устойчивости Lr9; 5 носителей гена Lr10; 7 носителей Lr26; 7 носителей Lr34 и 2 носителя гена Lr46. Полученные результаты могут быть использованы в селекционных программах Казахстана.
