ABSTRACT

Two quinoxaline dyes utilized in copper-electrolyte-based dye-sensitized solar cells (Cu-DSSCs) are theoretically investigated to analyze the impact of alkyl chains on dye performance. The investigation shows that ZS4, known for its record efficiency of up to 13.2 %, exhibits higher electron coupling and fewer binding sites for dye-[Cu(tmby)2]2+ interaction compared to ZS5. Contrary to common belief, alkyl chains are found to not only provide shielding but also hinder the interaction between dye and [Cu(tmby)2]2+ by influencing the optimal conformation of dyes, thereby impeding the charge recombination process. It is crucial to consider the influence of alkyl chains on dye conformation when discussing the relationship between dye structure and performance, rather than oversimplifying it as often done traditionally. Building on these findings, eight dyes are strategically designed by adjusting the position of the alkyl chain to further decrease charge recombination compared to ZS4. Theoretical evaluation of these dyes reveals that changing the alkyl chain on the nitrogen atom from 2-ethylhexyl (ZS4) to 1-hexylheptyl (D3-2) not only reduces the charge recombination rate but also enhances light harvesting ability. Therefore, D3-2 shows potential as a candidate for experimental synthesis of high-performance Cu-DSSCs with improved efficiency.

ABSTRACT

Polylactic acid (PLA) straws hold eco-friendly potential; however, residual diisocyanates used to enhance the mechanical strength can generate carcinogenic primary aromatic amines (PAAs), posing health risks. Herein, we present a rapid, comprehensive strategy to detecting PAAs in 18 brands of food-grade PLA straws and assessing their migration into diverse food simulants. Surface-enhanced Raman spectroscopy was conducted to rapidly screen straws for PAAs. Subsequently, qualitative determination of migrating PAAs into various food simulants (4 % acetic acid, 10 % ethanol, 50 % ethanol) occurred at 70 °C for 2 h using liquid chromatography-mass spectrometry. Three PAAs including 4,4'-methylenedianiline, 2,4'-methylenedianiline, and 2,4-diaminotoluene were detected in all straws. Specifically, 2,4-diaminotoluene in 50 % ethanol exceeded specific migration limit of 2 µg/kg, raising safety concerns. Notably, PAAs migration to 10 % and 50 % ethanol surpassed that to 4 % acetic acid within a short 2-hour period. Moreover, PLA straws underwent varying degrees of shape changes before and after migration. Straws with poly(butylene succinate) resisted deformation compared to those without, indicating enhanced heat resistance, while poly(butyleneadipate-co-terephthalate) improved hydrolysis resistance. Importantly, swelling study unveiled swelling effect wasn't the primary factor contributing to the increased PAAs migration in ethanol food simulant, as there was no significant disparity in swelling degrees across different food simulants. FT-IR and DSC analysis revealed higher PAAs content in 50 % ethanol were due to highly concentrated polar ethanol disrupting hydrogen bonds and van der Waal forces holding PLA molecules together. Overall, minimizing contact between PLA straws and alcoholic foods is crucial to avoid potential safety risks posed by PAAs.

ABSTRACT

Six luminescent europium organic complexes have been synthesized and studied for their luminescent properties. The synthesized complexes were analyzed through elemental analysis, XRD, SEM, EDAX, FT-IR, NMR and thermogravimetry. The complexes exhibit crystalline behavior and possess decent thermal stability. Photoluminescence study on complexes were conducted in both solid and solution states, the results indicate the characteristic red emission. With the addition of ancillary ligands, water molecules are replaced from inner coordination sphere, leading to enhanced luminescence properties. The colorimetric parameters (CIE, CP%, CCT, u', v') suggest aptness of these complexes in red light illuminating OLEDs. The J-O parameters were calculated experimentally and theoretically with the help of LUMPAC software. Theoretical and experimental results agree well reflecting the efficacy of the outcomes. As a result of red emission, these complexes could have interesting photonics applications. The biological studies indicate the probable use of these complexes in the medical industry.

ABSTRACT

Objectives: For early gastrointestinal lesions, size is an important factor in the selection of treatment. Virtual scale endoscope (VSE) is a newly developed endoscope that can measure size more accurately than visual measurement. This study aimed to investigate whether VSE measurement is accurate for early gastrointestinal lesions of various sizes and morphologies. Methods: This study prospectively enrolled patients with early gastrointestinal lesions ≤20 mm in size visually. Lesion sizes were measured in the gastrointestinal tract visually, on endoscopic resection specimens with VSE, and finally on endoscopic resection specimens using a ruler. The primary endpoint was the normalized difference (ND) of VSE measurement. The secondary endpoints were the ND of visual measurement and the variation between NDs of VSE and visual measurements. ND was calculated as (100 × [measured size - true size] / true size) (%). True size was defined as size measured using a ruler. Results: This study included 60 lesions from April 2022 to December 2022, with 20 each in the esophagus, stomach, and colon. The lesion size was 14.0 ± 6.3 mm (mean ± standard deviation). Morphologies were protruded, slightly elevated, and flat or slightly depressed type in 8, 24, and 28 lesions, respectively. The primary endpoint was 0.3 ± 8.8%. In the secondary endpoints, the ND of visual measurement was -1.7 ± 29.3%, and the variability was significantly smaller in the ND of VSE measurement than in that of visual measurement (p < 0.001, F-test). Conclusions: VSE measurement is accurate for early gastrointestinal lesions of various sizes and morphologies.

ABSTRACT

Growing evidences showed that heavy metals exposure may be associated with metabolic diseases. Nevertheless, the mechanism underlying arsenic (As) exposure and metabolic syndrome (MetS) risk has not been fully elucidated. So we aimed to prospectively investigate the role of serum uric acid (SUA) on the association between blood As exposure and incident MetS. A sample of 1045 older participants in a community in China was analyzed. We determined As at baseline and SUA concentration at follow-up in the Yiwu Elderly Cohort. MetS events were defined according to the criteria of the International Diabetes Federation (IDF). Generalized linear model with log-binominal regression model was applied to estimate the association of As with incident MetS. To investigate the role of SUA in the association between As and MetS, a mediation analysis was conducted. In the fully adjusted log-binominal model, per interquartile range increment of As, the risk of MetS increased 1.25-fold. Compared with the lowest quartile of As, the adjusted relative risk (RR) of MetS in the highest quartile was 1.42 (95% confidence interval, CI: 1.03, 2.00). Additionally, blood As was positively associated with SUA, while SUA had significant association with MetS risk. Further mediation analysis demonstrated that the association of As and MetS risk was mediated by SUA, with the proportion of 15.7%. Our study found higher As was remarkably associated with the elevated risk of MetS in the Chinese older adults population. Mediation analysis indicated that SUA might be a mediator in the association between As exposure and MetS.

ABSTRACT

This chapter summarizes the epidemiological study design of natural immune epidemiology studies based on recent COVID-19-related research. The epidemiological studies on antiviral innate immunity have mainly included randomized controlled trials (RCTs) and observational studies. Importantly, this chapter will discuss how to use these methodologies to answer an epidemiological question of natural immunity in the viral infection process based on previous studies. An observational case- or cohort-based study of antiviral innate immunity may support this theoretical hypothesis but is not appropriate for clinical practice or treatment. RCTs are the gold standard for epidemiological studies and occupy a greater role in the hierarchy of evidence.

ABSTRACT

This work established a quantitative method to access the shear stability of aerobic granular sludge (AGS) and validated its feasibility by using the mature AGS from a pilot-scale (50 tons/day) membrane bioreactor (MBR) for treating real municipal wastewater. The results showed that the changing rate (ΔS) of the peak area (S) of granule size distribution (GSD) exhibited an exponential relationship (R2≥0.76) with the shear time (y=a-b·cx), which was a suitable indicative index to reflect the shear stability of different AGS samples. The limiting granule size (LGS) was defined and proposed to characterize the equilibrium size for AGS after being sheared for a period of time, whose value in terms of Dv50 showed high correlation (R2=0.92) with the parameter a. The free Ca2+ (28.44-34.21 mg/L) in the influent specifically interacted with polysaccharides (PS) in the granule's extracellular polymeric substance (EPS) as a nucleation site, thereby inducing the formation of Ca precipitation to enhance its Young's modulus, while Ca2+ primarily interacted with PS in soluble metabolic product (SMP) during the initial granulation process. Furthermore, the Young's modulus significantly affected the parameter a related to shear stability (R2=0.99). Since the parameter a was more closely related (R2=1.00) to ΔS than that of the parameter b or c, the excellent correlation (R2=0.99) between the parameter a and the wet density further verified the feasibility of this method.

ABSTRACT

ABSTRACT Purpose: This study aimed to compare the safety and effectiveness of intraocular pressure reduction between micropulse transscleral cyclophotocoagulation and "slow cook" transscleral cyclophotocoagulation in patients with refractory primary open-angle glaucoma. Methods: We included patients with primary open angle glaucoma with at least 12 months of follow-up. We collected and analyzed data on the preoperative characteristics and postoperative outcomes. The primary outcomes were a reduction of ≥20% of the baseline value (criterion A) and/or intraocular pressure between 6 and 21 mmHg (criterion B). Results: We included 128 eyes with primary open-angle glaucoma. The preoperative mean intraocular pressure was 25.53 ± 6.40 and 35.02 ± 12.57 mmHg in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups, respectively (p<0.001). The mean intraocular pressure was reduced significantly to 14.33 ± 3.40 and 15.37 ± 5.85 mmHg in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups at the last follow-up, respectively (p=0.110). The mean intraocular pressure reduction at 12 months was 11.20 ± 11.46 and 19.65 ± 13.22 mmHg in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups, respectively (p<0.001). The median preoperative logMAR visual acuity was 0.52 ± 0.69 and 1.75 ± 1.04 in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups, respectively (p<0.001). The mean visual acuity variation was −0.10 ± 0.35 and −0.074 ± 0.16 in the micropulse- and "slow cook" transscleral cyclophotocoagulation, respectively (p=0.510). Preoperatively, the mean eye drops were 3.44 ± 1.38 and 2.89 ± 0.68 drugs in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups, respectively (p=0.017), but those were 2.06 ± 1.42 and 1.02 ± 1.46 at the end of the study in the "slow cook" and micropulse transscleral cyclophotocoagulation groups, respectively (p<0.001). The success of criterion A was not significant between both groups. Compared with 11 eyes (17.74%) in the "slow cook" transscleral cyclophotocoagulation group, 19 eyes (28.78%) in the micropulse transscleral cyclophotocoagulation group showed complete success (p=0.171). For criterion B, 28 (42.42%) and 2 eyes (3.22%) showed complete success after micropulse- and "slow cook" transscleral cyclophotocoagulation, respectively (p<0.001). Conclusion: Both techniques reduced intraocular pressure effectively.

ABSTRACT

Introdução: O desenvolvimento da família é influenciado por diversos fatores de sua organização interna e de ordem ambiental, social, cultural, econômica e política. Em contexto de pobreza os riscos são maiores. Fatores de proteção, como boa organização familiar e rede social de apoio podem diminuir as consequências negativas da pobreza. São escassas as pesquisas longitudinais sobre vulnerabilidade e resiliência nas famílias. Objetivo: Este artigo descreve o desenvolvimento de três famílias ao longo de 15 anos, estudadas por meio de entrevistas em casa, parte de uma coorte populacional de um bairro de Porto Alegre (RS). Buscaram-se associações entre a qualidade das relações nessas famílias e sua saúde física e mental, especialmente a do filho, foco da pesquisa. Métodos: Selecionaram-se no arquivo da pesquisa as três primeiras famílias (do total de 148) das quais se tinham os resultados completos das cinco visitas realizadas aos quatro meses e aos dois, quatro, nove e 15 anos de um filho. Realizou-se análise qualitativa dos registros em busca de categorias para compreender a vida e as relações interpessoais nas famílias. O estudo foi realizado em conjunto por duas pesquisadoras, médicas especialistas em desenvolvimento humano. As categorias identificadas na análise e estudadas nas cinco etapas foram: configuração familiar, situação socioeconômica, situações traumáticas, saúde física, saúde relacional e mental, evolução cognitiva e escolar do filho. Resultados: As três famílias, todas de classe C, com filhos sem problemas de saúde física, tiveram evolução suficientemente boa, apesar de todas enfrentarem múltiplos problemas, inclusive separações e mortes precoces. A relação com o sistema de saúde e escola era boa e similar para as três. A jovem com menos problemas de saúde mental foi aquela que sofreu perdas mais importantes: morte dos pais. Tinha uma estrutura familiar multigeracional sólida desde a primeira infância, com relações interpessoais predominantemente colaborativas e amorosas. Conclusões: O artigo busca avançar na compreensão da resiliência nas famílias em situações de vulnerabilidade. Concluímos que essas três famílias, uma delas mais que as outras, foram suficientemente saudáveis na tarefa de educar seus filhos sem desenvolverem problemas mentais graves. Propomos que o bom desenvolvimento se associa com a adequação e amorosidade dos cuidados com a etapa do ciclo vital, mesmo enfrentando situações problemáticas. Essas qualidades precisam estar associadas à estabilidade socioeconômica básica e a bons serviços de saúde e escola.


Introduction: Family development is influenced by it's internal organization and environmental factors, socioeconomic, cultural and political. In poor contexts there are more risks to development. Protection factors like good family organization and social network may decrease the risks. Longitudinal research about vulnerability and resilience in families is scarse. Objective: This article describes the development of three families over 15 years through interviews at home. The families were part of a populational cohort of a neighborhood in Porto Alegre (RS). We looked for links between the quality of relationships and the physical and mental health of these families, especially of the child focus of the research. Methods: We selected in the research archives the first three families (of a total of 148) for which we had full results of the five interviews at four months and two, four, nine and fifteen years of a child. We did a qualitative analysis of the records looking for parameters to understand the life and interpersonal relationships of these families. This study was done by two researchers, both experts in Human Development. The categories identified in the analysis of the five phases were: family structure, socioeconomic situation, traumatic experiences, physical, mental and relational health and cognitive evolution of the child. Results: All three families belonged to economical class C. The children were in good physical health and had sufficiently good general development, having faced multiple problems, including parental separation and early parental death. The relationship with the health and school systems was good in all of them. The youth with less mental health problems was the one who suffered the heaviest loss: early death of both parents. Her family had strong multigenerational ties since her early days, with predominant collaborative and loving relationships. Conclusions: This article aims to contribute to the comprehension of resilience in families in the context of vulnerability. We can say that these three families were healthy enough in the task of bringing up children without any serious mental health problem. We suggest that healthy development is associated with loving interfamily relationships adequate to each phase of development, notwithstanding dramatic events. This needs to be supported by basic economic stability and adequate school and health systems.

Proponemos que el buen desarrollo se asocia con el amor y adecuación de los cuidados a la etapa del ciclo vital, aun enfrentando situaciones problemáticas. Esas calidades necesitan estar asociadas a la estabilidad socioeconómica básica y buenos servicios de salud y escuela.

ABSTRACT

Resumo Enquadramento: A generatividade tem sido associada à resiliência e à satisfação com a vida na velhice, incluindo entre a população lésbica, gay, bissexual e transgénero (LGBT+) mais velha. Objetivo: Analisar as propriedades psicométricas da Loyola Generativity Scale (LGS) e da Generative Behavior Checklist (GBC) para idosos espanhóis LGBT + (com mais de 50 anos). Metodologia: Foi realizado um estudo psicométrico com 141 idosos espanhóis LGBT+ com o objetivo de examinar a validade de construto (análise fatorial exploratória), a validade convergente e a fiabilidade (consistência interna) da LGS e da GBC. Resultados: Os métodos de análise paralela e a análise fatorial exploratória sugeriram um modelo de dois fatores para ambos os instrumentos com boa adequação da amostra. A LGS explicou 45,1% da variância e apresentou uma consistência interna de 0,78. O GBC explicou 41,76% da variância e apresentou uma consistência interna de 0,879. Foi encontrada uma correlação positiva e estatisticamente significativa entre a satisfação com a vida e as escalas generativas. Foi também observada uma correlação positiva e significativa (rs = 0,310) entre os dois instrumentos. Conclusão: Ambos os instrumentos demonstraram ser válidos e fiáveis para medir a generatividade em idosos espanhóis LGBT+.


Abstract Background: Generativity has been associated with resilience and life satisfaction in older age, including among lesbian, gay, bisexual, and transgender (LGBT+) older adults. Objective: To examine the psychometric properties of the Loyola Generativity Scale (LGS) and Generative Behavior Checklist (GBC) for Spanish LGBT+ older adults (over the age of 50). Methodology: A psychometric study was conducted with 141 Spanish LGBT+ older adults to examine the construct validity (exploratory factor analysis), convergent validity, and reliability (internal consistency) of the LGS and the GBC. Results: Parallel and exploratory factor analyses suggested a two-factor model with good sample adequacy for both scales. The LGS explained 45.1% of the variance and had an internal consistency of 0.78. The GBC explained 41.76 % of the variance and had an internal consistency of 0.879. A positive and statistically significant correlation was found between life satisfaction and the generative scales. A positive and significant correlation (rs = 0.310) was also observed between both instruments. Conclusion: Both instruments proved valid and reliable for measuring generativity in Spanish LGBT+ older adults.

ABSTRACT

Introducción: Las hospitalizaciones por Ambulatory Care Sensitive Conditions es un indicador que mide la utilización de los servicios hospitalarios por problemas de salud que podrían haber sido prevenidos en el primer nivel de atención. El concepto se refiere a los procesos en que la atención ambulatoria efectiva puede ayudar a disminuir los riesgos de hospitalización, en un segundo nivel de atención. El objetivo del estudio fue construir y validar una lista uruguaya de problemas de salud sensibles a cuidados ambulatorios (PSSCA) según CIE-10. Metodología: Para la construcción de la lista inicial de códigos de PSSCA se realizó una revisión de los listados existentes y se propuso un listado inicial que fue validado a través del Método Delphi. Se propone un listado de 99 códigos diagnósticos de PSSCA adaptado a nuestro entono sanitario. Los mismos permiten identificar y cuantificar problemas de salud que pueden producir hospitalizaciones potenciamente evitables mediante cuidados ambulatorios accesibes y oportunos en el primer nivel de atención. Resultados: Se conformó un panel de 12 expertos. A partir de los datos obtenidos, considerando los 99 diagnósticos clasificados por CIE-10, éstos se pueden subclasificar en función de si la patología es infecciosa o no, obteniendo un resultado general de 62 patologías en un total de 99 que pueden ser clasificadas como infecciosas, lo que se corresponde a un 62 %. Discusión: De la comparación de la lista uruguaya de PSSCA a la que hemos arribado y las listas validadas utilizadas para la construcción inicial del listado de patologías propuesto, podemos decir que la primera presenta un mayor porcentaje de coincidencia con la lista de patologías de Bello Horizonte. Podemos mencionar que la mayoría de los problemas de salud identificados con base en el listado de PSSCA, son sensibles de ser resueltos con la atención primaria oportuna y de calidad que podría evitar o disminuir de una manera significativa su hospitalización. Conclusiones: Este trabajo describe el proceso de construcción y validación de una lista de códigos de PSSCA adaptados al contexto uruguayo a través del método Delphi. Hemos arribado a un listado que comprende un total de 99 diagnósticos, agrupadas en un total de diecinueve categorías que considera la especificidad del contexto uruguayo del indicador.


Introduction: Hospitalizations for Ambulatory Care Sensitive Conditions is an indicator that measures the use of hospital services for health problems that could have been prevented at the first level of care. The concept refers to the processes in which effective outpatient care can help reduce the risks of hospitalization, at a second level of care. The objective of the study was to build and validate a Uruguayan list of health problems sensitive to outpatient care (PSS-CA) according to ICD-10. Methodology: To construct the initial list of PSSCA codes, a review of the existing lists was carried out and an initial list was proposed that was validated through the Delphi Method. A list of 99 PSSCA diagnostic codes adapted to our healthcare environment is proposed. They make it possible to identify and quantify health problems that can lead to potentially avoidable hospitalizations through accessible and timely outpatient care at the first level of care. Results: A panel of 12 experts was formed. From the data obtained, considering the 99 diagnoses classified by ICD-10, these can be subclassified depending on whether the pathology is infectious or not, obtaining a general result of 62 pathologies in a total of 99 that can be classified as infectious, which corresponds to 62%. Discussion: From the comparison of the Uruguayan list of PSSCA that we have arrived at and the validated lists used for the initial construction of the proposed list of pathologies, we can say that the first presents a higher percentage of coincidence with the list of pathologies of Bello Horizonte . We can mention that most of the health problems identified based on the PSSCA list are sensitive to being resolved with timely and quality primary care that could prevent or significantly reduce hospitalization. Conclusions: This work describes the process of construction and validation of a list of PSSCA codes adapted to the Uruguayan context through the Delphi method. We have arrived at a list that includes a total of 99 diagnoses, grouped into a total of nineteen categories that consider the specificity of the Uruguayan context of the indicator.

Discussão: A partir da comparação da lista uruguaia de PSSCA a que chegamos e das listas validadas utilizadas para a construção inicial da lista de patologias proposta, podemos dizer que a primeira apresenta um maior percentual de coincidência com a lista de patologias de Belo Horizonte. Podemos mencionar que a maioria dos problemas de saúde identificados com base na lista PSSCA são sensíveis para serem resolvidos com cuidados primários oportunos e de qualidade que possam prevenir ou reduzir significativamente a hospitalização. Conclusões: Este trabalho descreve o processo de construção e validação de uma lista de códigos PSSCA adaptados ao contexto uruguaio através do método Delphi. Chegamos a uma lista que inclui um total de 99 diagnósticos, agrupados em um total de dezenove categorias que consideram a especificidade do contexto uruguaio do indicador.

ABSTRACT

BACKGROUND: With the aging population, the increasing prevalence of chronic non-communicable diseases, and the diversified needs for primary health care (PHC) medicines, it is necessary to rethink the functional role of the supply of PHC medicines. This study aims to evaluate the supply of PHC medicines and the status of meeting PHC medicine needs. METHODS: The mixed-methods study was conducted to evaluate the supply of PHC medicines in Shandong Province. In the quantitative study, survey questionnaires were distributed to county hospitals, township hospitals, and patients, and a prescription review was performed in township hospitals. In the qualitative study, semi-structured interviews were conducted with the pharmacy managers, physicians, and patients in county hospitals, township hospitals, and village clinics. A senior pharmacist from a tertiary hospital who has rich experience on the indications for medicine use, accompanied us on a visit to inspect the PHC pharmacies to survey medicine equipment with a professional perspective. RESULTS: Quantitative analysis revealed that 211 county hospitals and 1,581 township hospitals participated in the survey, revealing the median annual frequency of medicine shortages of 5.0 times for county hospitals and 2.0 times for township hospitals. Of the 6,323 patient medication surveys, after excluding 152 patients not involved in medication use, 945 (15.3%) indicated medicine shortages, with half of these attributable to institutions lacking required medicines (52.8%). On average, the prescription qualified rate of 37 township hospitals was 72.2%. Four final themes emerged during the qualitative data analysis: (1) Supply of PHC medicines; (2) Solutions to the shortage of off-list medicines; (3) Appropriateness of PHC medicines list; (4) Pharmacist workforce development and pharmacy services. CONCLUSIONS: The discrepancy between patients' need for PHC medicine and present medicine supply is noteworthy. It is suggested that governments should optimize the existing lists to adequately meet patient medicine needs and prioritize medicines for chronic diseases, which is also particularly important for developing countries. Integrated health care may be a novel strategy to establish unified medicines list and achieve uniform pharmaceutical services in PHC.

ABSTRACT

BACKGROUND: A dramatic decline in mental health of people worldwide in the early COVID-19 pandemic years has not recovered. In rural and remote Australia, access to appropriate and timely mental health services has been identified as a major barrier to people seeking help for mental ill-health. From 2020 to 2021 a care navigation model, Navicare, was co-designed with rural and remote communities in the Greater Whitsunday Region of Central Queensland in Australia. The Exploration, Preparation, Implementation and Sustainment (EPIS) framework was used to design and guide multiple aspects of a multisite study, The Bridging Study, to evaluate the implementation of Navicare in Australia. METHODS: A community-engaged hybrid effectiveness-implementation study design will focus on the tailored implementation of Navicare at three new sites as well as monitoring implementation at an existing site established since 2021. Study outcomes assessed will include sustained access as the co-primary outcome (measured using access to Navicare mental health referral services) and Proctor's Implementation Outcomes of feasibility, acceptability, appropriateness, adoption, fidelity, implementation cost, and sustainability. Data collection for the implementation evaluation will include service usage data, community consultations, interviews, and workshops; analysed using mixed methods and guided by EPIS and other implementation frameworks. Pre-post effectiveness and cost-consequence study components are embedded in the implementation and sustainment phases, with comparison to pre-implementation data and value assessed for each EPIS phase using hospital, service, and resource allocation data. A scaling up strategy will be co-developed using a national roundtable forum in the final year of the study. Qualitative exploration of other aspects of the study (e.g., mechanisms of action and stakeholder engagement) will be conducted. DISCUSSION: Our study will use tailoring to local sites and a community-engaged approach to drive implementation of a mental health care navigation service in rural and remote Australia, with expected benefits to mental healthcare access. This approach is consistent with policy recommendations nationally and internationally as building blocks for rural health including the World Health Organization Framework for Action on Strengthening Health Systems to Improve Health Outcomes.

ABSTRACT

BACKGROUND: Problematic overstudying is a compulsive and pathological overinvolvement in studying leading to harm and considerable functional impairments. It is conceptualized as "study addiction," a precursor to work addiction. It has been investigated within the addictive behaviours framework in general populations of students for over a decade. A previous study analysed the problem among young musicians as a particularly vulnerable group. It found some important differences in potential personality risk factors among music academy students compared to general populations of students and showed an important role of social anxiety. The current study aimed to validate these findings in a separate larger sample and extend them by investigating the role of music performance anxiety (MPA). PARTICIPANTS AND PROCEDURE: The study was conducted among 213 students of music academies. Valid and reliable measures of study addiction, MPA, Big Five personality and well-being were used. RESULTS: The results showed that MPA played a similar role as social anxiety in terms of being a predictor, mediator, and moderator of the main replicated effects supporting the hypothesised mechanisms regulating study addiction. However, extraversion was not associated with study addiction in multiple hierarchical regression analysis, but conscientiousness and neuroticism were. Study addiction was associated with indicators of decreased well-being, above and beyond MPA, and personality. CONCLUSIONS: These results show that MPA plays an analogous role to social anxiety and that the role of Big Five personality in study addiction among young musicians requires further investigation due to inconsistent findings.

ABSTRACT

Background: Chimeric antigen receptor T-cell (CAR-T) therapy, a rapidly emerging treatment for cancer that has gained momentum since its approval by the FDA in 2017, involves the genetic engineering of patients' T cells to target tumors. Although significant therapeutic benefits have been observed, life-threatening adverse pulmonary events have been reported. Methods: Using SAS 9.4 with MedDRA 26.1, we retrospectively analyzed data from the Food and Drug Administration's Adverse Event Reporting System (FAERS) database, covering the period from 2017 to 2023. The analysis included the Reporting Odds Ratio Proportional Reporting Ratio Information Component and Empirical Bayes Geometric Mean to assess the association between CAR-T cell therapy and adverse pulmonary events (PAEs). Results: The FAERS database recorded 9,400 adverse events (AEs) pertaining to CAR-T therapies, of which 940 (10%) were PAEs. Among these CAR-T cell-related AEs, hypoxia was the most frequently reported (344 cases), followed by respiratory failure (127 cases). Notably, different CAR-T cell treatments demonstrated varying degrees of association with PAEs. Specifically, Tisa-cel was associated with severe events including respiratory failure and hypoxia, whereas Axi-cel was strongly correlated with both hypoxia and tachypnea. Additionally, other CAR-T therapies, namely, Brexu-cel, Liso-cel, Ide-cel, and Cilta-cel, have also been linked to distinct PAEs. Notably, the majority of these PAEs occurred within the first 30 days post-treatment. The fatality rates varied among the different CAR-T therapies, with Tisa-cel exhibiting the highest fatality rate (43.6%), followed by Ide-cel (18.8%). Conclusion: This study comprehensively analyzed the PAEs reported in the FAERS database among recipients of CAR-T cell therapy, revealing conditions such as hypoxia, respiratory failure, pleural effusion, and atelectasis. These CAR-T cell therapy-associated events are clinically significant and merit the attention of clinicians and researchers.

ABSTRACT

Objectives: Olanzapine is used for treating bipolar disorder (BPD); however, the optimal initial dosing regimen is unclear. The present study aimed to investigate the optimal olanzapine initial dosage in patients with BPD via model-informed precision dosing (MIPD) based on a real-world study. Methods: Thirty-nine patients with BPD from the real-world study were collected to construct the MIPD model. Results: Weight, combined used quetiapine influenced olanzapine clearances in patients with BPD, where the clearance rates were 0.152:1 in patients with or without quetiapine under the same weight. We simulated olanzapine doses once a day or twice a day, of which twice a day was optimal. Without quetiapine, for twice-a-day olanzapine doses, 0.80, 0.70, and 0.60 mg/kg/day were suitable for 40- to 56-kg BPD patients, 56- to 74-kg BPD patients, and 74- to 100-kg BPD patients, respectively. With quetiapine, for twice-a-day olanzapine doses, 0.05 mg/kg/day was suitable for 40- to 100-kg BPD patients. Conclusion: This study was the first to investigate the optimal olanzapine initial dosage in patients with BPD via MIPD based on a real-world study, providing clinical reference for the precision medication of olanzapine in BPD patients.

ABSTRACT

Abundance estimation is frequently an objective of conservation and monitoring initiatives for threatened and other managed populations. While abundance estimation via capture-mark-recapture or spatially explicit capture-recapture is now common, such approaches are logistically challenging and expensive for species such as boreal caribou (Rangifer tarandus), which inhabit remote regions, are widely dispersed, and exist at low densities. Fortunately, the recently developed 'close-kin mark-recapture' (CKMR) framework, which uses the number of kin pairs obtained within a sample to generate an abundance estimate, eliminates the need for multiple sampling events. As a result, some caribou managers are interested in using this method to generate an abundance estimate from a single, non-invasive sampling event for caribou populations. We conducted a simulation study using realistic boreal caribou demographic rates and population sizes to assess how population size and the proportion of the population surveyed impact the accuracy and precision of single-survey CKMR-based abundance estimates. Our results indicated that abundance estimates were biased and highly imprecise when very small proportions of the population were sampled, regardless of the population size. However, the larger the population size, the smaller the required proportion of the population surveyed to generate both accurate and reasonably precise estimates. Additionally, we also present a case study in which we used the CKMR framework to generate annual female abundance estimates for a small caribou population in Jasper National Park, Alberta, Canada, from 2006 to 2015 and compared them to existing published capture-mark-recapture-based estimates. Both the accuracy and precision of the annual CKMR-based abundance estimates varied across years and were sensitive to the proportion of pairwise kinship comparisons which yielded a mother-offspring pair. Taken together, our study demonstrates that it is possible to generate CKMR-based abundance estimates from a single sampling event for small caribou populations, so long as a sufficient sampling intensity can be achieved.

ABSTRACT

Objected: To evaluate the association between osteoarthritis (OA) and Parkinson's disease (PD) in adults in the United States. Methods: Using 2011-2020 NHANES data, a cross-sectional study of 11,117 adults over the age of 40 was conducted. Univariate logistic regression and multivariate logistic regression were used to analyze the relationship between arthritis and PD. In addition, stratified analysis was used to examine whether the relationship between arthritis and PD was interactive with age, gender, race, education, BMI. Results: In this study, a total of 11,117 participants were included, and we found that osteoarthritis was positively correlated with the development of PD compared with non-arthritis patients [1.95 (1.44 ~ 2.62)] (p < 0.001). After adjusting the covariates, the results are still stable. Conclusion: PD patients were positively correlated with OA. Among people with OA, there was a 95% increased risk of PD compared to people without arthritis. Therefore, when treating OA, attention should be paid to the increased risk of PD. In the meantime, further studies are needed to explore the link between OA and PD patients.

ABSTRACT

Background and Aims: In the neurobiological theory of attention, the orienting network mainly supports the temperamental regulatory function in infancy, with soothing methods such as visual attention distraction influencing its development. The attention distraction method chosen for soothing is thought to be influenced by maternal sensitivity, which has been found to decrease with poor maternal mental health. We hypothesize that the degree of maternal distress may affect the choice of attention distraction soothing method. Further, individual differences in being soothed by attention distraction will be associated with the temperamental regulation function in infancy/toddlerhood. Method: Structural equation modeling (SEM) was conducted on longitudinal data at 6 and 24 months on a sample (N = 1892) drawn from the sub-cohort of the Japan Environment and Children's Study (JECS). Temperament was examined through the short Infant Behavior Questionnaire-Revised (Japanese version) and the Early Childhood Behavior Questionnaire (Japanese version). Distress in caregivers was measured through the Kessler Psychological Distress Scale (Japanese version) at prenatal and 1-year-postnatal stages. Individual differences in using visual distraction soothing methods were also measured using tailor-made items. Results: Postnatal maternal distress at 12 months was negatively related to the tendency to use visual attention distraction as a soothing method (ß = -0.06, p = 0.006) at 24 months. When we applied the subscale of the temperamental regulatory factor in SEM, the more the mothers chose the distraction method for soothing, i.e., the more the toddlers experienced it, the higher their attention shifting scores (ß = 0.07, p = 0.002). Conclusion: The findings support the view that caregivers' choice of method for distracting offspring's attention from distress may be associated with the development of self-regulation during infancy and toddlerhood.

ABSTRACT

Introduction: University students are a special population group characterized by changes in BMI values over the subsequent years of education, with an upward tendency to BMI. The presented study aims to evaluate the prevalence of overweight and obesity and their determinants in medical students during the 2-year follow-up observation. Materials and methods: We analyzed data collected from the first follow-up of the cohort study named "POLLEK" conducted among medical students at the Medical University of Silesia in Katowice. Students were followed at two points of time: in their inaugural year of studies (the academic year 2021/2022, T1, N = 427), and subsequently in their second year (the academic year 2022/2023, T2, N = 335). Results: In the initial year of evaluation, 371 individuals (86.9%) exhibited normal body weight, 47 (11.0%) were overweight, and 9 (2.1%) were classified as obese. Subsequent assessments during the second year revealed the following distribution: 277 students (84.2%) with normal body weight, 40 (12.2%) classified as overweight, and 12 (3.6%) identified as obese. In summary, regardless of the academic year, an increased risk of being overweight or obese was significantly associated with dissatisfaction with personal health, financial strain, and a diet abundant in animal products. Conclusion: The results of our study confirmed an increase in the prevalence of overweight or obesity among medical students during the 2-year follow-up observation. Significant determinants of overweight or obesity among medical students were: dissatisfaction with individual health status, male sex, financial deficiencies, and a diet abundant in meat consumption.
