PURPOSE
In Japan, two types of tests for diagnosing olfactory disorders, T and T (T&T) olfactometry and intravenous olfactory tests, are covered by insurance and performed on patients with olfactory disorders. This study examined the validity of these olfactory tests and whether psychophysical or morphological tests are more helpful in evaluating olfactory disorders.
METHODS
We evaluated patients who visited our department and underwent two types of olfaction tests and sinus computed tomography (CT). Data regarding the age, sex, peripheral blood eosinophil percentage, presence of bronchial asthma, diagnoses, olfactory symptom score, results of the two olfactory tests, and CT findings in eligible patients were extracted from medical records and retrospectively reviewed.
RESULTS
One hundred and sixty-three patients underwent all tests during the study period. The results of the T&T olfactometry and intravenous olfactory tests were significantly correlated. However, only the results of T&T olfactometry and olfactory cleft opacification on CT were statistically significant predictors of the olfactory symptom scores.
CONCLUSION
T&T olfactometry and CT evaluations of olfactory cleft opacification helped evaluate olfactory dysfunction. It is important to note that intravenous olfactory tests are best performed with careful control and not blindly to assess olfactory disorders.

UNLABELLED
The number of children eligible for Paediatric Palliative Care has dramatically increased over the years, with few tools that can help with early identification. The Paediatric Palliative Screening Scale is a dedicated German, English, and Portuguese screening tool. We aimed to translate and perform a cultural adaptation to the Italian setting of the Paediatric Palliative Screening Scale. This paper was a descriptive observational cross-sectional study. We carried it out in two consecutive steps: (1) translation and back translation and (2) cultural adaptation through a Delphi process. Twenty Paediatric Palliative Care national experts were invited to judge the content and structure of the translated scale and to assess the appropriateness and clarity of each question. Consensus was defined as 70% or more of experts agreeing with each item's appropriateness and clarity. The Italian version of the Paediatric Palliative Screening Scale was obtained after two rounds of Delphi. After the second round of consultation, a substantial increase in experts' consensus was found, especially for questions 1.1, 3.2 and 3.3 (from 56.3 to 93.8%), and reaching more than 83% for all the revised items.
CONCLUSIONS
The Paediatric Palliative Screening Scale is a reliable tool that can assist in timely evaluating children who qualify for Paediatric Palliative Care. The tool can be used in Italian healthcare settings with its cultural adaptation.
WHAT IS KNOWN
• Despite the lack of early diagnosis techniques, there is a significant increase in the number of children entitled to Paediatric Palliative Care. • A specific screening tool called the Paediatric Palliative Screening Scale determines a child's suitability for paediatric palliative treatment.
WHAT IS NEW
• The Paediatric Palliative Screening Scale is necessary to assess the psychosocial needs of patients eligible for Paediatric Palliative Care. The Italian scale has good content and face validity ensuring equivalence between the original and target populations.

Postoperative complications of radical gastrectomy seriously affect postoperative recovery and require accurate risk prediction. Therefore, this study aimed to develop a prediction model specifically tailored to guide perioperative clinical decision-making for postoperative complications in patients with gastric cancer. A retrospective analysis was conducted on patients who underwent radical gastrectomy at the First Affiliated Hospital of Nanjing Medical University between April 2022 and June 2023. A total of 166 patients were enrolled. Patient demographic characteristics, laboratory examination results, and surgical pathological features were recorded. Preoperative abdominal CT scans were used to segment the visceral fat region of the patients through 3Dslicer, a 3D Convolutional Neural Network (3D-CNN) to extract image features and the LASSO regression model was employed for feature selection. Moreover, an ensemble learning strategy was adopted to train the features and predict postoperative complications of gastric cancer. The prediction performance of the LGBM (Light Gradient Boosting Machine), XGB (XGBoost), RF (Random Forest), and GBDT (Gradient Boosting Decision Tree) models was evaluated through fivefold cross-validation. This study successfully constructed a model for predicting early complications following radical gastrectomy based on the optimal algorithm, LGBM. The LGBM model yielded an AUC value of 0.9232 and an accuracy of 87.28% (95% CI, 75.61-98.95%), surpassing the performance of other models. Through ensemble learning and integration of perioperative clinical data and visceral fat radiomics, a predictive LGBM model was established. This model has the potential to facilitate individualized clinical decision-making and the early recovery of patients with gastric cancer post-surgery.

In recent years, instrumental improvements have enabled the spread of mass spectrometry-based lipidomics platforms in biomedical research. In mass spectrometry, the reliability of generated data varies for each compound, contingent on, among other factors, the availability of labeled internal standards. It is challenging to evaluate the data for lipids without specific labeled internal standards, especially when dozens to hundreds of lipids are measured simultaneously. Thus, evaluation of the performance of these platforms at the individual lipid level in interlaboratory studies is generally not feasible in a time-effective manner. Herein, using a focused subset of sphingolipids, we present an in-house validation methodology for individual lipid reliability assessment, tailored to the statistical analysis to be applied. Moreover, this approach enables the evaluation of various methodological aspects, including discerning coelutions sharing identical selected reaction monitoring transitions, pinpointing optimal labeled internal standards and their concentrations, and evaluating different extraction techniques. While the full validation according to analytical guidelines for all lipids included in a lipidomics method is currently not possible, this process shows areas to focus on for subsequent method development iterations as well as the robustness of data generated across diverse methodologies.

The Nile Tilapia (Oreochromis niloticus), a gonochoristic teleost fish with a XX/XY sex-determination system, is an ideal model for investigating gonadal sex differentiation. During gonadal differentiation, the expression of cyp19a1a in XX gonads and dmrt1 in XY gonads are required for undifferentiated tissues to develop into ovary or testis. In this study, quantitative real-time RT-PCR assessed the expression of cyp19a1a and dmrt1 genes in gonads and tail fin tissues. Differences in gene expression mean among sexually differentiated fish were analyzed using two-way analysis of variance (ANOVA) and validation of mixed model using discriminant analysis (DA) for morphometric traits and the gene expression in gonads and tail fin tissues used to validate and utilize them in discriminating sexes in sex-differentiated Nile Tilapia fish. The results revealed that, cyp19a1a gene expression in female ovaries was more significant than dmrt1 in male testis. In the other hand, the dmrt1 gene expression in the tail fin was higher in males than females. Both, cyp19a1a and dmrt1 genes, can discriminate fish sexes by 100% by using their expression in tail fin tissues. In conclusion, the cyp19a1a and dmrt1 genes could be used as a genetic marker to discriminate between the Nile Tilapia sexes, whereas used as an indicator for ovarian or testis differentiation in sexually differentiated Nile Tilapia using tail fin tissues. It is worth mentioning that this is the first investigation for using cyp19a1a and dmrt1 genes from Nile Tilapia tail fin tissues in sex determination.

Review
In health research, there is a need for comprehensive survey instruments capable of assessing the multidimensionality and variability of sex/gender. The research project DIVERGesTOOL was conducted in response to this need, which has become increasingly evident in recent years. The aim was to develop an application-oriented toolbox for the assessment of sex/gender diversity in quantitative health-related research in Germany.The development process followed a participatory design, as representatives of large epidemiological studies in Germany were directly involved. During four collaborative workshops, a toolbox was developed that contains several different elements. The basic items are a generally usable set of three different questionnaire items based on the two-step approach. They are recommended as a replacement for the binary sex or gender item that are currently routinely used in health-related research. In addition, the toolbox contains further exemplary questionnaire items for specific research questions or study populations. The developed items were supplemented with detailed instructions for their application and additional information. The toolbox is an open online resource accessible to any user ( https://www.uni-bremen.de/divergestool-projekt/divergestool-toolbox ).In the long term, the DIVERGesTOOL is intended to support researchers in integrating sex/gender diversity into their own research and thus to contribute to more sex/gender sensitivity in health-related research and valid findings.

Here we present a task developed to probe implicit learning of a complex motor skill. This task addresses limitations related to task complexity noted in the literature for methods investigating implicit motor learning, namely the serial reaction time task and continuous tracking task. Specifically, the serial reaction time task is limited by the kinematic simplicity of the required movement and the continuous tracing task faces time-on-task confounds and limitations in the control of task difficulty. The task presented herein addresses these issues by employing a kinematically complex multi-articular movement that controls factors that contribute to task difficulty: stimulus animation velocity and trajectory complexity. Accordingly, our objective was to validate the use of this task in probing implicit motor learning, hypothesizing that participants would learn one of the repeating stimuli implicitly. Participants engaged in six blocks of training whereby they first observed and then reproduced a seemingly random complex trajectory. Repeated trajectories were embedded amongst random trajectories. In line with the hypothesis, error for the repeated trajectories was decreased in comparison to that observed for the random trajectories and 73% of participants were unable to identify one of the repeated trajectories, demonstrating the occurrence of implicit learning. While the task requires minor alteration to optimize learning, ultimately the findings underline the task's potential to investigate implicit learning of a complex motor skill.

Review
BACKGROUND
Although there is increasing awareness of the health risks of air pollution as a global issue, few studies have focused on the methods for assessing individuals' perceptions of these risks. This scoping review aimed to identify previous research evaluating individuals' perceptions of air pollution and its health effects, and to explore the measurement of perceptions, as a key resource for health behaviour.
METHODS
The review followed the methodological framework proposed by Arksey and O'Malley. PubMed and Web of Science were searched. After initial and full-text screening, we further selected studies with standardised scales that had previously been tested for reliability and validity in assessing awareness and perceptions.
RESULTS
After full-text screening, 95 studies were identified. 'Perception/awareness of air quality' was often measured, as well as 'Perception of health risk.' Only nine studies (9.5%) used validated scaled questionnaires. There was considerable variation in the scales used to measure the multiple dimensions of risk perception for air pollution.
CONCLUSION
Few studies used structured scales to quantify individuals' perceptions, limiting comparisons among studies. Standardised methods for measuring health risk perception are needed.

OBJECTIVE
The objective of this study was to evaluate the efficacy of the combined treatment of Ying-Huang Decoction and San-ao Decoction compared to conventional treatment alone in patients with sepsis-associated acute lung injury (S-ALI) and to assess its potential mechanisms for improving clinical symptoms, reducing inflammatory response, and promoting respiratory function recovery.
METHODS
We included 84 S-ALI patients admitted to our hospital between January 2021 and January 2023. The patients were divided into a control group and an observation group, with 42 patients in each group. The control group received conventional treatment, while the observation group received the combined treatment of Ying-Huang Decoction and San-ao Decoction in addition to conventional treatment. The study was conducted in accordance with the principles of the Helsinki Declaration and received ethical approval. The main outcome measures assessed included symptom scores, levels of inflammatory factors, lung injury scores (such as LIS scores), respiratory function parameters (such as PVPI and EVLWL levels), and the incidence of adverse reactions.
RESULTS
The observation group receiving the combined treatment of Ying-Huang Decoction and San-ao Decoction demonstrated favorable outcomes compared to the control group. Significant improvements were observed in the observation group's symptom scores compared to the control group (P < .05). Patients in the observation group experienced a notable alleviation of clinical symptoms associated with S-ALI. In terms of inflammatory response, the observation group showed significantly lower levels of inflammatory factors, including IL-6, CRP, and IL-17, compared to the control group (P < .01). This suggests that the combined decoction treatment effectively reduced the systemic inflammatory response in S-ALI patients. Lung injury scores, as assessed by the LIS, were significantly reduced in the observation group compared to the control group (P < .05). This indicates that the combined treatment contributed to the mitigation of lung tissue damage in S-ALI patients. Respiratory function parameters, such as PVPI and EVLWL levels, showed significant improvement in the observation group compared to the control group (P < .01), indicating enhanced respiratory function.
CONCLUSION
The combined treatment of Ying-Huang Decoction and San-ao Decoction, in addition to conventional treatment, demonstrated beneficial effects in the management of S-ALI, leading to improved clinical symptoms, reduced inflammatory response, and enhanced respiratory function. These findings suggest the potential integration of traditional Chinese medicine approaches, such as Ying-Huang Decoction and San-ao Decoction, in the treatment of S-ALI, providing additional options for clinicians and potentially improving patient outcomes. It is important to acknowledge the limitations of this study, such as its retrospective design and the need for further research with larger sample sizes to validate the results and minimize potential biases.
