UNASSIGNED: The quick sequential [sepsis-related] organ failure assessment (qSOFA) acts as a prompt to consider possible sepsis. The contributions of individual qSOFA elements to assessment of severity and for prediction of mortality remain unknown.
UNASSIGNED: A total of 3974 patients with community-acquired pneumonia were recruited to an observational prospective cohort study. The area under the receiver operating characteristic curve (AUROC), odds ratio, relative risk and Youden\'s index were employed to assess discrimination.
UNASSIGNED: Respiratory rate ≥22/min demonstrated the most superior diagnostic value, indicated by largest odds ratio, relative risk and AUROC, and maximum Youden\'s index for mortality. However, the indices for altered mentation and systolic blood pressure (SBP) ≤100 mm Hg decreased notably in turn. The predictive validities of respiratory rate ≥22/min, altered mentation and SBP ≤100 mm Hg were good, adequate and poor for mortality, indicated by AUROC (0.837, 0.734 and 0.671, respectively). Respiratory rate ≥22/min showed the strongest associations with SOFA scores, pneumonia severity index, hospital length of stay and costs. However, SBP ≤100 mm Hg was most weakly correlated with the indices.
UNASSIGNED: Respiratory rate ≥22/min made the greatest contribution to parsimonious qSOFA to assess severity and predict mortality. However, the contributions of altered mentation and SBP ≤100 mm Hg decreased strikingly in turn. It is the first known prospective evidence of the contributions of individual qSOFA elements to assessment of severity and for prediction of mortality, which might have implications for more accurate clinical triage decisions.
Respiratory rate ≥22/min demonstrated the most superior diagnostic value.Respiratory rate ≥22/min showed the strongest association with severity.Respiratory rate ≥22/min, altered mentation and SBP ≤100 mm Hg predicted mortality well, adequately and poorly, respectively.

BACKGROUND: The term contribution is a key feature of approaches to positive youth development but has yet to be adequately defined. The purposes of this study were to identify properties that underlie contribution and to establish a theoretical definition of the construct.
METHODS: A two-phase scoping review was conducted. The first phase involved the systematic search, selection, and analysis of studies from which six properties of contribution were identified and a preliminary theoretical definition was constructed. In the second phase expert judges rated the degree to that the proposed definition and the six properties of contribution fit with their conceptualization of the construct on a 6-point scale.
RESULTS: Mean ratings for the definition and the six properties ranged from 5.05 to 5.70. Judges\' ratings for the overall definition of contribution and the six properties were evaluated using Aiken\'s content validity coefficient (V). All V coefficients ranged in size from 0.81 to 0.94 and were statistically significant (p\'s < .01) indicating that the definition of contribution and the corresponding six properties fit well with experts\' conceptualizations of the construct.
CONCLUSIONS: This study provides a theoretical definition of contribution that will serve as a foundation upon which future research in the area of positive youth development can build.

The arsenic (As) release from sediments in great lakes is affected by various factors. In this study, the characteristics of As release from sediments was investigated, and the As sources and sinks with the strengths in sediments from different areas (grass-type, algae-type, and grass-algae alternation areas) in great shallow lakes (Taihu Lake, China) were analyzed, and the influence of P competition in the process of As release was also studied. The results showed that changing trend of the values of equilibrium As concentration in sediments were consistent with the regional changes (0 to 28.12 µg/L), and the sediments from algae-type areas had the higher values. The sediments from western lake and northwest lake bay were a strong As and a weak P source, and the north lake bay had the opposite trend of these two regions. Intense P source competition with As from the sediments occurred in algae-type areas. The grass-type areas had strong As and P retention capacities, indicating a sink role of sediment with high As and P sorption capacities. The degree of As and P saturation had similar trend in sediments, and the grass-type areas had the higher values, 18.3%-21.4% and 15.31%-20.34%, respectively. Contribution analysis results showed that most of As release contribution was from the bottom (30-50 cm) sediments, and the surface (0-10 cm) sediments from algae-type areas contributed more to the overlying water than other region.

Due to the combined influences of marine and terrestrial disturbances, the sources of microplastics (MPs) in mangrove ecosystems are complex and diverse. Previous studies have inferred the possible involvement of mariculture activities as a potential source of mangrove MPs based on the characteristics of MPs. However, the direct contributions of mariculture-derived MPs to mangrove MPs remain largely unknown. In this study, we systematically investigated the fate of MPs in the discharge of mariculture wastewater by quantifying the source contributions of mariculture-derived MPs to rivers and mangroves. The majority of detected MPs were transparent fibers, with their composition primarily comprising materials commonly used in mariculture activities such as polyvinylpyrrolidone (PVP), polyethylene terephthalate (PET), and nylon. The partial least squares path model elucidated the relationships among the composition of MPs in ponds, rivers, and mangroves, indicating that ponds exert a substantial direct effect on mangroves, particularly significant in the sediments (63.68%). Water turbidity, sediment carbon content, and sediment particle size are key ecological factors influencing the abundance of mariculture-derived MPs. This study provides compelling evidence regarding the sources of mangrove MPs and novel insights into mitigating the dissemination of MPs.

Self-regulation is essential for maintaining harmonious social connections and sustaining groups, yet little research has examined how individuals regulate their actions for the benefits of groups and which self-regulatory strategies promote effective self-regulation (active engagement and disengagement) in group contexts. In three experiments, focusing on identity groups (family and friends in Study 1) and two distinct functional groups (workplace teams in Study 2; sports teams in Study 3), we investigated whether mental contrasting of a desired future with the obstacle of reality, compared to indulging in the desired future, facilitates expectancy-dependent contributions for the benefits of groups. We assessed participants\' expectancies of successfully contributing to their groups and varied the mode of thought (mental contrasting vs. indulging). Contributions to groups were measured 1 week (Studies 1 and 2) and 3 weeks later (Study 3). Results showed that mental contrasting guided people to align their actions with expectancy levels; the higher their expectancy, the more people contributed to their groups. In contrast, indulging resulted in insensitivity to expectancy levels. Our findings suggest the potential applicability of the mental contrasting strategy for promoting effective self-regulation in various group settings and provide insights into designing interventions to enhance individuals\' engagement in groups.

OBJECTIVE: Chronic diseases contribute significantly to healthy years lost (HYLs). It is critical to investigate which are the most contributing diseases to enable enhancing health programs\' effectiveness in improving health expectancy. This paper investigates disease-specific contributions to years lived with chronic diseases in Algeria and examines their recent evolution.
METHODS: We used morbidity data from the last three waves of the Multiple Indicator Cluster Surveys of 2006, 2012-13, and 2018-19. The studied chronic diseases included hypertension, cardiovascular diseases (CVDs), joint diseases, respiratory diseases, and diabetes. We calculated disease-specific contributions using the cause-deleted health expectancy approach. Then, we analyzed time changes and gender-based differences in contributions.
RESULTS: The leading cause of HYLs in women is hypertension, followed by diabetes, joint diseases, CVDs, and respiratory diseases. The same ranking applies to men, with joint diseases coming last. The time evolution of relative disease-specific contributions shows an increase in CVDs for women and diabetes for both genders, against a decrease for the other diseases.
CONCLUSIONS: To improve chronic disease-free life expectancy in Algeria, effective prevention programs must be implemented, with an emphasis on hypertension and diabetes. Further investigation into the risk factors affecting the prevalence and incidence of these diseases is also required.

Wastewater treatment plants (WWTPs) are considered a significant microplastic discharge source. To evaluate the amount and characteristics of microplastics discharged from WWTPs in South Korea, we selected 22 municipal WWTPs nationally and investigated microplastics at each treatment stage. The mean microplastic removal efficiency by WWTPs was >99%, and most of the microplastics were removed by sedimentation with the second clarifier during wastewater treatment. Consequently, the microplastic removal efficiency of WWTPs did not significantly differ from that of the adopted wastewater treatment technology because a second clarifier was applied in most WWTPs. However, for WWTPs operating a tertiary treatment process, the removal efficiency was enhanced compared with that of WWTPs discharging after a second clarifier. Although the microplastic removal efficiency was high by WWTP, the discharge contribution to the water environment could not be ignored because of the amount of treated wastewater, resulting in an increase of 5.8-270.9 items/m3 of microplastics in the receiving water. The characteristics of microplastics in WWTPs, including their components, shape, and size, were also evaluated. The most detected components included polytetrafluoroethylene and polyester. Most microplastics detected were categorized as fragments and fibers, while other types were hardly detected. The size of more than 70% of the microplastics detected in WWTPs was under 300 μm, implying that the size of microplastics required to control in WWTPs was much smaller than the defined size of microplastics. An evaluation of the correlation between other pollution factors and microplastic abundance did not reveal positive correlations, and microplastic occurrence was not affected by changing seasons, which may need to be evaluated with further studies. Research should also be performed on the effect of influent sources on the level of microplastic abundance and fate of ultrafine plastics in WWTPs.

Marine litter caused by discharge of mismanaged plastic waste is considered to be one of the major environmental challenges by the international society. With the annual increase of plastic production, a growing number of plastic products are being used in people\'s daily lives. A large number of these plastics end up as waste emitted into rivers and subsequently into oceans through the effects of downpours or wind, posing a threat to the marine ecosystem. In this study, we developed a riverine plastic transport model based on catchment topography and social-economic factors. By applying reasonable compromise on the complexity of the model, this compromised simplified process-based model has the innovative capability to estimate plastic emissions effectively under the current conditions of limited data availability for model inputs. Compared to existing models, this novel model can also resolve challenges related to the contributions of various land use types and transport stages to plastic emissions into the oceans. To further explore the applicability of our results on a global scale, certain input parameter such as the proportion of mismanaged waste is crucial for users to acquire. Here, taking the S river catchment as our study area, the tourism-driven seasonal variation of land-based plastic emissions was quantified. According to our estimation, the emission flux in S river catchment in 2020 was 68 to 280 tons. 62.4% of riverine plastics reached the ocean. Although urban areas are the predominant contributors to the total emission flux, the contributions from other land use types such as forests and cultivated areas are also unignorable. For instance, forests and cultivated areas contribute 25.7% and 6.3%, respectively, even surpassing the contributions from high tourist activity (5.8%). Stricter waste collection legislations are imperatively needed particularly in these regions.

Probiotic Bacillus strains can solve the problems of single flavor and long fermentation time of fermented products caused by the lack of certain functional genes and insufficient metabolism ability of fermenter strains (Lactobacillus and Bifidobacterium) at the present stage. There is a lack of systematic evaluation and review of probiotic Bacillus as food fermentation agents. In this paper, it is observed that probiotic Bacillus strains are involved to varying degrees in liquid-state, semi-solid state, and solid-state fermentation and are widely present in solid-state fermented foods. Probiotic Bacillus strains not only produce abundant proteases and lipases, but also effective antifungal lipopeptides and extracellular polymers, thus enhancing the flavor, nutritional value and safety of fermented foods. Bacillus with probiotic qualities is an underutilized group of probiotic food fermentation agents, which give a potential for the development of fermentation technology in the food business and the integration of ancient traditional fermentation techniques.

Increases in mental health problems have been observed during COVID-19 pandemic. Therefore, this topic of research became a priority, especially at the academic level. The objectives of this review were to summarize academic contribution to mental health research during the era of COVID-19. A scoping review of studies conducted at different academic institutions and examining alterations in mental health during the pandemic during the last three years was conducted. Fifty-five studies were included. These focused on different mental health changes that occurred in the era of COVID-19 such as changes in work habits or existing psychological conditions, COVID-19-related fear depression, anxiety and stress. Most of the included studies were observational (76.7%). The majority of the publications were published in Scimago Journal Rank Q1 journals (57.1%). The average number of citations per publication was 15.3 ± 30.13 [0-125]. The number of citations was higher in papers with international collaboration of authors (p = 0.031). Publications with COVID-19 as a main objective were more cited than papers not directly related to this subject (25.9 ± 39.45 vs 4.14 ± 3.2; p = 0.044). Mental health problems are a common response to the COVID-19 pandemic. The contribution of academic universities to different mental health research studies that took place during COVID-19 outbreak have underlined this reality. However, more representative research from other institutional settings will be needed, particularly in vulnerable populations.
