BackgroundSuicide is one of the main causes of mortality in the world, accounting for more fatalities than homicide, war, human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), breast cancer, and malaria. Significantly, the biggest risk factors for suicide in the general population are having already attempted suicide and suicidal ideation. Despite the availability of studies on suicidal ideation among people living with HIV/AIDS (PLWHA) in Ethiopia, the results are inconsistent. Thus, a systematic review and meta-analysis was conducted to estimate the pooled prevalence of suicidal ideation among people living with HIV/AIDS.MethodsA systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. To find papers published in the English language before 20 May 2023, the electronic databases of Medline, Science Direct, Excerpta Medica Database, Cochrane Library, African Journals Online (AJOL), and Google Scholar were searched. The DerSimonian and Laird method for random effects models was used to estimate the pooled prevalence of suicidal ideation with a 95% confidence interval in STATA V.14.0 statistical software. To test for heterogeneity between studies and publication bias, respectively, forest plots and funnel plots were used. Additionally, leave-one-out sensitivity was conducted.ResultsA total of nine studies with 3,411 study participants were included in this systematic review and meta-analysis. The pooled prevalence of suicidal ideation among PLWHA was 20.55% (95% CI 14.76, 26.33). Being female (Odds ratio (OR) = 4.27, 95% CI = 2.29, 7.97), living alone (OR = 5.02, 95% CI = 2.15, 11.64), poor social support (OR = 3.80, 95% CI = 2.56, 5.65), perceived stigma (OR = 3.50, 95% CI = 1.55, 7.87), depression (OR = 5.08, 95% CI = 2.55, 11.48), undisclosed HIV status (OR = 4.8, 95% CI = 2.10, 10.93), and World Health Organization HIV clinical stages of III or IV (OR = 4.40, 95% CI = 2.95, 6.58) were significantly associated with suicidal ideation.ConclusionSuicidal ideation among PLWHA is high in Ethiopia. Therefore, emphasis should be given to psychiatric assessment and interventions with a special focus on individuals having the associated factors.Systematic Review RegistrationPROSPERO (CRD42023429613).
Effects of Aging in Wood Casks on Anthocyanins Compositions, Volatile Compounds, Colorimetric Properties, and Sensory Profile of Jerez Vinegars
Authors: Uysal Reyhan Selin 
Published: September 2024

The Jerez (Sherry) vinegars, including Vinagre de Jerez, Reserva, and Gran Reserva, are crafted from Sherry wines and are protected under the Denomination of Origin in Spain. The aim of this study was to (i) characterize the physicochemical properties and composition; (ii) investigate the impact of the aging process on color properties, phenolics, volatile compounds, and sensorial profiles; and (iii) find a marker for tracing the authenticity of non-aged (Apto) and aged Jerez vinegars. The phenolic components were identified through LC-MS/MS, whereas the volatile compounds were examined using the GC-MS/MS technique. As the aging progressed, a decrease was observed in the levels of flavonol and phenolic acids, with anthocyanin components being undetectable in non-aged and aged samples. In the Gran Reserva variety, 2-methylbutyl acetate, acetic acid, and ethanol emerged as the predominant volatile substances. The presence of oaklactone and ethyl butanoate components served as marker substances to authenticate the Gran Reserva. Additionally, alterations in color properties were noted, marked by a decrease in yellow content and an increase in the red component depending on aging. Furthermore, novel sensory descriptors, such as vanilla, clove, woody, and nutty notes, and winy character emerged in the samples with prolonged aging.

Relevance. Periodontitis and metabolic syndrome are interrelated conditions that often aggravate each other through shared pathogenic mechanisms, highlighting the need for integrated immunomodulatory therapeutic approaches. Despite this, existing literature presents inconsistent data regarding the interplay between periodontitis and metabolic syndrome, as well as limited insights into the potential benefits of omega-3 polyunsaturated fatty acids (ω-3 PUFAs) as an adjuvant therapy. Specifically, the role of ω-3 PUFAs in modulating the inflammatory response and mitigating bone resorption remains inadequately explored. Therefore, this study aims to evaluate the inflammatory response and osteoresorption in periodontal tissues under the combined conditions of periodontitis and metabolic syndrome, while also assessing the therapeutic effects of ω-3 PUFAs.Materials and methods. This experimental study was conducted using 30 male Wistar rats, which were randomly assigned to one of five groups: a control group, a periodontitis group, a combined periodontitis and metabolic syndrome group, a periodontitis group treated with omega-3 fatty acids, and a combined periodontitis and metabolic syndrome group treated with omega-3 fatty acids. The study employed several research methodologies. Biochemical analyses were performed to confirm the presence of metabolic syndrome. Histopathological and morphometric assessments were conducted to evaluate the inflammatory response, the extent of osteoresorption, and the number of osteoclasts in the periodontal tissues. Additionally, molecular genetic analysis was used to measure the relative mRNA expression levels of key inflammatory and osteoclastogenic markers, including TNFα, IL-1β, RANK, and OPG.Results. The data demonstrated that metabolic syndrome in laboratory animals significantly exacerbates both the pro-inflammatory response and the extent of lacunar osteoclastic bone resorption. Administration of ω-3 PUFAs at a dose of 40 mg/kg over 30 days led to a statistically significant reduction in inflammatory infiltration within the periodontal tissues (3.17 ± 0.21 in the control group vs. 1.83 ± 0.21 in the treated group, р = 0.001) and a decrease in the number of osteoclasts (3,75 ± 0,45 in the control group vs. 1,75 ± 0,35 in the treated group, р = 0.003). Additionally, there was a notable reduction in the expression levels of TNFα, IL-1β, and RANK mRNA. Similar but less pronounced effects were observed in the group with combined metabolic syndrome following ω-3 PUFA administration.Conclusion. These findings enhance the current understanding of the interplay between periodontitis and metabolic syndrome, highlighting the potential of ω-3 PUFAs as a preventive or therapeutic intervention. ω-3 PUFAs may be effective in mitigating inflammatory responses and bone resorption, both in cases of isolated periodontitis and when accompanied by metabolic syndrome.

Melting and solidification of lunar regolith are pivotal for comprehending the evolutionary dynamics of lunar volcanism, geology, and impact history. Additionally, insights gained from these processes can contribute to the advancement of in situ resource utilization technologies, for instance additive manufacturing and resource extraction systems. Herein, we conduct the direct observation of the melting and rapid solidification of lunar particles returned by the Chang’E 5 mission. The melting temperature and melting sequence were obtained. Bubble generation, growth, and release were clearly observed, with a maximum bubble diameter of 5 µm, which is supposed to be according to the release of volatiles that embedded in the particles. During the solidification process, evident crystallization occurred with incremental crystal growth rate approximately of 27 nm/s. Scanning electron microscopy and energy-dispersive x-ray spectroscopy results verified that the Fe-rich mineral crystalizes first. These results would improve the understanding of the evolution of lunar volcanism, geology, and impact history.

Published: September 2024

Abstract
A novel plasmonic sensor, which is composed of a metal-insulator-metal (MIM) waveguide and a coupled split-square-ring resonator, is proposed and investigated by utilizing the two-dimensional (2D) finite-difference time-domain (FDTD) method. The optimized results demonstrate that the proposed sensor is highly sensitive to variations of refractive index (RI) and temperature, i.e. the RI and temperature sensitivities are up to 2040 nm RIU−1 and −1.2 nm/°C, respectively. Numerical simulations reveal that the sensing performance can still be further improved via optimization of the structure. This research may open up new schemes in realizing high-sensitive biosensors with compact configurations.

Published: September 2024

Abstract
Tungsten samples with fuzz nanostructures on the surface were generated using helium plasma with different incident ion energies, and then fuzz tungsten oxide electrodes were prepared by calcination. The photoelectrochemical (PEC) properties and stability of the samples were measured, and the dependence on the incident ion energy was discussed. The mechanism of the fuzz structure to enhance the PEC performance of tungsten oxide was analyzed by scanning electron microscope, X-ray diffraction, and electrochemical impedance spectroscopy. The results show that the fuzzy sample fabricated with higher ion energy has greater PEC performance, which is mainly caused by the increase in active surface area.

Resumo
O presente estudo traz reflexões sobre a importância das práticas alimentares tradicionais no âmbito da saúde coletiva e os impactos do racismo no processo de invisibilização desses saberes. O arcabouço teórico foi coletado na base de dados lilacs, Sciello, Pubmed, Google scholar, as expressões utilizadas foram: “saúde nas comunidades quilombolas” com 87 achados, “hábitos alimentares das comunidades quilombolas” 4 achados ,“Segurança Alimentar e Nutricional (SAN) em comunidades quilombolas” com 10 artigos e Práticas Alimentares em comunidades quilombolas com 5 artigos, sendo que esta última busca foram encontrados artigos em comum com os dois títulos anteriores não havendo dissociação entre “hábitos e práticas”. Os poucos artigos encontrados no que se diz respeito às práticas alimentares nas comunidades quilombolas corroboram com o modelo biomédico de formação dos profissionais de saúde, que estimula a produção do conhecimento etnocêntrico e invisibiliza os saberes tradicionais. Os alimentos de origem agrícola é a principal fonte de renda dos moradores da comunidade quilombola, dentre os alimentos cultivados temos: Feijão, Mangalô, Andu, Aipim, Milho, jenipapo, batata, amendoim, hortaliças entre outros, sendo que os seus derivados são produzidos tanto para consumo interno quanto para comercialização. Concluímos que o racismo se apresenta de diversas formas e as novas gerações de profissionais e estudantes, além de combater o racismo, devem também contracolonizar o mito da democracia racial através de estudos científicos que comprovem a relevância dos saberes tradicionais no âmbito da saúde, com a finalidade de valorizar e resgatar esses saberes provenientes dos povos tradi
Dynamic Programming, Neuro-Dynamic Programming, Rollout Method and Model Predictive Control to Optimal Control of a Fermentation Process
Authors: Ilkova Tatiana , Petrov Mitko 
Published: September 2024

This work presents the use of dynamic programming (DP), neuro-dynamic programming (NDP), rollout algorithm (RA) and model predictive control (MPC) for optimal control of batch cultivation of the yeast Kluyveromyces marxianus var. lactis MC5. DP is a widespread method for solving problems related to optimization and optimal process control. To reduce the “curse of dimensionality”, NDP has been implemented as an alternative. In NDP, a neural network is used to solve the dimensionality problem. A simpler NDP method, called RA, is used to approximate the optimal cost through the cost of a relatively good suboptimal policy, called the baseline policy. RA is a suboptimal method for deterministic and stochastic problems that can be solved by DP. In this paper we also present off-line MPC technique for tracking of constrained fermentation systems and it overcomes the problem by off-line optimizations prior to implementation. MPC is used to provide perturbation feedback and it is developed theoretical on base a controller as an illustration how we can avoid disturbances in the process optimisation. The developed control algorithm-combined NDP and MPC ensures maximum biomass production at the end of the process and feedback during disturbances and process stability and shows that robust stability can be ensured.

Published: September 2024

A SVEIR epidemic model with a delay in diagnosis is studied in a constant and variable environment. The mathematical analysis shows that the dynamics of the model in the constant environment are completely determined by the magnitude of the delay-induced reproduction number . We established that if < 1, the disease-free equilibrium is globally asymptotically stable, and when > 1 the endemic equilibrium is globally asymptotically stable. In the variable environment, the model undergoes a transcritical bifurcation for = 1 leading to changes in the stability of the equilibrium points. The analytical effect of the delays in epidemic diagnosis is investigated. A minimum diagnosis rate αmin has been determined to face or control the disease effectively. Finally, numerical illustrations were presented to support the theoretical results.

A meta-analysis on the relationship between subjective cognitive failures as measured by the cognitive failures questionnaire (CFQ) and objective performance on executive function tasks
Authors: Goodhew Stephanie C. , Edwards Mark 
Published: September 2024

AbstractThe Cognitive Failures Questionnaire (CFQ) has been widely used as a measure of subjective cognitive function in everyday life for decades. However, the evidence on how it relates to objective performance on executive function tasks is mixed. One possible reason for these mixed results is that the CFQ has selective relationships with some aspects of executive function and not others. Here, therefore, we classified tasks according to an influential framework of executive functions—switching, updating, inhibition, and we also considered the Sustained Attention to Response Task (SART) as a category because it was custom designed to gauge cognitive failures. We synthesized a large body of available evidence and performed four Bayesian meta-analyses on the relationship between CFQ scores and objective performance on executive function tasks in these four categories. Results suggested that CFQ scores were associated with objective performance on SART (18 effect sizes, μ = −.19, BF10 = 18.03, i.e., 18.03 times more evidence of a relationship versus no relationship), updating working memory (49 effect sizes, μ = −.06, BF10 = 17.80), and inhibition tasks (41 effect sizes, μ = −.07, BF10 = 15.40), whereas there was not definitive evidence regarding switching (34 effect sizes, μ = −.06, BF10 = .50, i.e., two times greater evidence for no relationship). This suggests that subjective cognitive function can predict objective performance on at least some executive function tasks. We discuss methodological and theoretical factors that constrain the maximum observable correlation and consider the relative insights that subjective measures versus task performance provide.

PT XYZ is a company engaged in ship repair and maintenance services and port management services. The problems faced by PT XYZ in carrying out its business lines are related to the effective and efficient operational managerial activities of raw material warehousing. Problem solving steps are carried out by testing data processing and analysis using the shared storage method as a solution step related to the problem of warehousing layout and optimization. Problem solving with the shared storage method is a method of reconditioning the warehousing layout with the principle of First in First out or fast moving where the layout of goods is classified based on the order of the flow of goods movement according to the operational needs of PT XYZ activities. Based on the calculation results, if the company applies the proposed layout, there is an average distance savings of 4 m2. The layout of the placement of raw materials based on the proposed improvements has a more organized condition and facilitates the flow of goods movement as well as inputting the flow of goods in and out which can be more efficient if the goods are organized and inputted administratively, this also affects the quality of goods.
