RESUMO
Influenza exposures early in life are believed to shape future susceptibility to influenza infections by imprinting immunological biases that affect cross-reactivity to future influenza viruses. However, direct serological evidence linked to susceptibility is limited. Here we analysed haemagglutination-inhibition titres in 1,451 cross-sectional samples collected between 1992 and 2020, from individuals born between 1917 and 2008, against influenza B virus (IBV) isolates from 1940 to 2021. We included testing of 'future' isolates that circulated after sample collection. We show that immunological biases are conferred by early life IBV infection and result in lineage-specific cross-reactivity of a birth cohort towards future IBV isolates. This translates into differential estimates of susceptibility between birth cohorts towards the B/Yamagata and B/Victoria lineages, predicting lineage-specific birth-cohort distributions of observed medically attended IBV infections. Our data suggest that immunological measurements of imprinting could be important in modelling and predicting virus epidemiology.

Background: Given the growing population of older adults globally, e-Health plays an indispensable role in the chronic disease management of multimorbidity. However, qualitative evidence that synthesizes the experiences of older adults with multimorbidity using e-Health service is currently lacking. The objective was to explore the experiences and perceptions of e-Health care in community-based settings among the older adults with multimorbidity. Methods: Seven electronic databases including PubMed, The Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, Embase, Web of Science, China National Knowledge Infrastructure, and Chinese BioMedical Literature were searched, and the search was limited to studies from inception to September 1, 2023. Screening, data extraction, and quality appraisal were conducted independently by two reviewers. Thomas and Harden's thematic synthesis methodology was applied to synthesize the original themes. The methodological quality of included studies was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research, and the confidence of synthesized themes was evaluated by the Confidence in the Evidence from Reviews of Qualitative Research approaches. Results: Ten studies with moderate methodological quality met eligibility criteria and were included finally. Studies were conducted in four countries with 235 participants who were living with multiple chronic conditions. Among the 10 included studies, 37 credible findings were extracted and interpreted into 3 synthesized themes and 12 subthemes: (1) advantages and benefits perceived during e-Health service, (2) multidimensional challenges and negative experience posed by e-Health service, and (3) preferences, suggestions, and expectations for future e-Health improvement. The confidence in the majority of the three final synthesized themes was rated between "low" and "moderate" scales. Conclusions: The findings of this study provide new insights into implementing tailored e-Health care for older adults with multimorbidity. Further research should emphasize on realizing the potential value of e-Health service based on users' needs and perspectives to promote age-friendliness in geriatric practice.
RESUMO
The presence of burrowing mammals can have extensive effects on plants and soils, creating bare soil patches in alpine meadows and potentially altering plant-soil carbon (C) and nitrogen (N). This study focuses on the plateau pika (Ochotona curzoniae) to examine the responses of plant-soil C and N to a small burrowing mammal from quadrat scale to plot scale. The density of active burrow entrances in disturbed plots was used as an indicator of the disturbance intensity of plateau pikas. The study found that the below-ground biomass (BGB) and its C and N, as well as soil C and N concentrations were significantly lower in bare soil areas than in vegetated areas and undisturbed plots. This shows that the quadrat scale limited the estimation of the C and N sequestration potential. Therefore, further research on the plot scale found that the disturbance by plateau pika significantly reduced plant biomass and BGB carbon stock. However, plateau pika did not affect soil C and N stocks or ecosystem C and N stocks. These findings suggest the bare soil patches formed by plateau pika caused plant and soil heterogeneity but had a trade-off effect on plant-soil C and N stocks at the plot scale. Nevertheless, moderate disturbance intensity increased the C and N sequestration potential in grassland ecosystems. These results provide a possible way to estimate how disturbance by small burrowing mammals affects C and N cycling in grassland ecosystems while accurately assessing the effects of small burrowing mammal densities on C and N in grassland ecosystems.

INTRODUCTION: The knowledge of barriers from the parental perspective is essential for facilitating shared decision-making in the field of pediatric asthma. METHOD: Participants who were parents of children with a diagnosis of asthma were recruited, and in-depth, semistructured interviews were conducted. The interview transcripts were analyzed thematically using framework methods. RESULTS: Seventeen participants undertook interviews. Three themes and nine subthemes emerged: (1) decision-making need level-limited understanding of decision-making knowledge, ambiguity regarding self-empowerment roles, and lack of family member support; (2) decision-making support level-insufficient ability to evaluate information, inefficient communication with health care professionals, and excessive use of professional terminology; and (3) decision-making outcome level-doubts about the final decision-making choices, time constraints on decision-making, and absence of mechanisms to track decisions made. DISCUSSION: The findings would serve as crucial foundations for the development of decision-aid programs within the context of pediatric asthma.
RESUMO
OBJECTIVES: To examine the effectiveness of mindfulness-based interventions (MBIs) on psychological symptoms, motor symptoms, and quality of life in patients with Parkinson's disease (PD). METHODS: Published studies in Chinese and English languages, conducted from inception to March 2023, were identified by searching PubMed, Web of Science, Cochrane Library, CINAHL, PsycINFO, and two Chinese electronic databases. The systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses guidelines. RESULTS: Twelve studies were selected for quantitative syntheses. The impact of MBIs on reducing depression and anxiety, and improving mindfulness and quality of life in PD patients was statistically significant compared to the control group. However, no statistically significant effect on motor symptoms was observed. Subgroup analysis indicated that participants from Asia, those who received face-to-face sessions, and those whose sessions lasted 1.5 hours showed a more positive effect than other subgroups. CONCLUSIONS: Patients with PD may benefit from MBIs to improve psychological symptoms and quality of life. MBIs represent a pivotal non-pharmacological therapeutic approach in clinical practice. CLINICAL IMPLICATIONS: MBIs confer positive improvements in psychological well-being and quality of life in PD patients. However, it remains challenging to conclusively determine their efficacy in addressing motor symptoms.
RESUMO
The development of hydrogel adhesives with high mechanical resilience and toughness remains a challenging task. Hydrogels must exhibit high mechanical resilience to withstand the inevitable movement of the human body while simultaneously demonstrating strong wet tissue adhesion and appropriate toughness to hold and seal damaged tissues; However, tissue adhesion, toughness, and mechanical resilience are typically negatively correlated. Therefore, this paper proposes a highly resilient double-network (DN) hydrogel wound-sealing patch that exhibits a well-balanced combination of tissue adhesion, toughness, and mechanical resilience. The DN structure is formed by introducing covalently and non-covalently crosslinkable dopamine-modified crosslinkers and physically interactable linear poly(vinyl imidazole) (PVI). The resulting hydrogel adhesive exhibits high toughness and mechanical resilience due to the presence of a DN involving reversible physical intermolecular interactions such as hydrogen bonds, hydrophobic associations, cation-π interactions, π-π interactions, and chain entanglements. Moreover, the hydrogel adhesive achieves strong wet tissue adhesion through the polar hydroxyl groups of dopamine and the amine group of PVI. These mechanical attributes allow the proposed adhesive to effectively seal damaged tissues and promote wound healing by maintaining a moist environment.

Traditional fermented milk from the western Sichuan plateau of China has a unique flavor and rich microbial diversity. This study explored the quality formation mechanism in fermented milk inoculated with Lactobacillus brevis NZ4 and Kluyveromyces marxianus SY11 (MFM), the dominant microorganisms isolated from traditional dairy products in western nan. The results indicated that MFM displayed better overall quality than the milk fermented with L. brevis NZ4 (LFM) and K. marxianus SY11 (KFM), respectively. MFM exhibited good sensory quality, more organic acid types, more free amino acids and esters, and moderate acidity and ethanol concentrations. Non-targeted metabolomics showed a total of 885 metabolites annotated in the samples, representing 204 differential metabolites between MFM and LFM and 163 between MFM and KFM. MFM displayed higher levels of N-acetyl-L-glutamic acid, cysteinyl serine, glaucarubin, and other substances. The differential metabolites were mainly enriched in pathways such as glycerophospholipid metabolism, arginine biosynthesis, and beta-alanine metabolism. This study speculated that L. brevis affected K. marxianus growth via its metabolites, while the mixed fermentation of these strains significantly changed the metabolism pathway of flavor-related substances, especially glycerophospholipid metabolism. Furthermore, mixed fermentation modified the flavor and quality of fermented milk by affecting cell growth and metabolic pathways.
RESUMO
PURPOSE: Parenting style plays a pivotal role in children's chronic disease control. However, the relationship and underlying mechanism between parenting style and asthma control remain unclear. This study investigated the effects of parenting style on children's general self-efficacy, medication adherence and asthma control and the mediating effects of general self-efficacy and medication adherence among school-age children with asthma. DESIGN AND METHODS: A cross-sectional study with a convenience sampling approach was conducted. This study followed the STROBE guidelines. School-age children with asthma and their parents (N = 211) from pediatric respiratory clinics in China completed the General Questionnaire, Short-Egna Minnen av. Barndoms Uppfostran-Chinese, General Self-Efficacy Scale, Medication Adherence Questionnaire and Childhood Asthma Control Test. Structural equation modeling was used to examine the mediation models. RESULTS: Positive parenting style was positively correlated with child general self-efficacy, medication adherence and asthma control (r = 0.602, 0.572, 0.613, p < 0.001). Negative parenting style was negatively correlated with child general self-efficacy, medication adherence and asthma control (r = -0.535, -0.598, -0.586, p < 0.001). Structure Equation Modle (SEM) results indicated that the relationships between positive parenting style, negative parenting style and child asthma control were mediated by general self-efficacy (Effect Size [ES]: 0.209, 95%CI [0.075, 0.372]; and ES: -0.229, 95%CI [-0.387, -0.103], respectively) and medication adherence (ES: 0.128, 95%CI [0.032, 0.322]; and ES: -0.190, 95%CI [-0.432, -0.071], respectively) and together in serial (ES: 0.177, 95%CI [0.076, 0.295]; and ES: -0.118, 95%CI [-0.235, -0.020], respectively). CONCLUSIONS: Parenting style may impact child asthma through both child general self-efficacy and medication adherence. The study may provide useful intervention targets for improving asthma control. PRACTICE IMPLICATIONS: Nurses should encourage parents to increase positive parenting style while decreasing negative parenting style. Family interventions focusing on general self-efficacy and medication adherence may be advantageous to improve asthma control.

As part of its role in the World Health Organization's (WHO) Global Influenza Surveillance and Response System (GISRS), the WHO Collaborating Centre for Reference and Research on Influenza in Melbourne received a record total of 12,073 human influenza positive samples during 2022. Viruses were analysed for their antigenic, genetic and antiviral susceptibility properties. Selected viruses were propagated in qualified cells or embryonated hen's eggs for potential use in seasonal influenza virus vaccines. In 2022, influenza A(H3N2) viruses predominated over influenza A(H1N1)pdm09 and B viruses, accounting for 77% of all viruses analysed. The majority of A(H1N1)pdm09, A(H3N2) and influenza B viruses analysed at the Centre were found to be antigenically and genetically similar to the respective WHO recommended vaccine strains for the southern hemisphere in 2022. Of 3,372 samples tested for susceptibility to the neuraminidase inhibitors oseltamivir and zanamivir, two A(H1N1)pdm09 viruses showed highly reduced inhibition against oseltamivir.

Influenza virus-specific tissue-resident memory (Trm) CD8+ T cells located along the respiratory tract provide cross-strain protection against a breadth of influenza viruses. We show that immunization with a single-cycle influenza virus vaccine candidate (S-FLU) results in the deposition of influenza virus nucleoprotein (NP)-specific CD8+ Trm along the respiratory tract that were more cross-reactive against viral variants and less likely to drive the development of cytotoxic T lymphocyte (CTL) escape mutants, as compared to the lung memory NP-specific CD8+ T cell pool established following influenza infection. This immune profile was linked to the limited inflammatory response evoked by S-FLU vaccination, which increased TCR repertoire diversity within the memory CD8+ T cell compartment. Cumulatively, this work shows that S-FLU vaccination evokes a clonally diverse, cross-reactive memory CD8+ T cell pool, which protects against severe disease without driving the virus to rapidly evolve and escape, and thus represents an attractive vaccine for use against rapidly mutating influenza viruses.

BACKGROUND: COVID-19 caused mild to severe infections in humans. The long-term epidemic environment harms people's mental health. To explore the impact of the epidemic on people's mental and psychological conditions, we surveyed in Wenzhou. METHODS: We collected the data of people who visited the First Affiliated Hospital of Wenzhou Medical University for five types of mental and psychological diseases from January 2018 to December 2021. Then, taking December 2019 as the cut-off point, the 48-month data were divided into the pre-epidemic group and the dur-epidemic group. Based on the above data, statistical analysis was done. RESULTS: From 2018 to 2021, the number of initial diagnoses, the number of disease visits, and drug consumption for these five types of mental and psychological diseases were all on the rise. Compared with the number of disease visits for all disorders in both psychiatry and neurology departments, it was found that the growth rate of these five diseases was higher than the growth rate of all disorders. We found that the number of disease visits, drug consumption, and scale scores after the COVID-19 outbreak were significantly different from those before the outbreak (P < 0.05). And the number of disease visits positively correlated with drug consumption (P < 0.0001, r = 0.9503), which verified the stability of the data. CONCLUSION: The epidemic environment has had a long-term and negative impact on people's mental and psychological conditions. Therefore, whether or not the epidemic is receding, we still need to be concerned about the impact of COVID-19 on mental and psychological health.

AIM: In response to the ageing population and shortage of human resources for nursing care, China is piloting internet-based nursing services (nurses who provide this care are called online nurses). Nurses are the providers of this model, so it is important to understand their perceptions. We aim to explore nurses' perceptions of engaging in internet-based nursing services. DESIGN: This study is descriptive qualitative research, so the data were analysed using a descriptive qualitative research method based on the theory of planned behaviour, using thematic analysis. METHODS: With personal semi-structured interviews conducted by two Master of Science in Nursing with 18 online nurses and nine clinical nurses, terminated after information saturation. RESULTS: Nurses' emotional attitudes towards internet-based nursing services were generally positive, but their behavioural intentions were negative. Social support, hospital organisational climate and family responsibilities had a statistically significant impact on nurses' behavioural decisions. Internet-based nursing services place higher demands on nurses' knowledge and skills, and nurses are most concerned with ensuring patient and nurse safety. PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution.

BACKGROUND: Frailty is a well-recognized risk factor for adverse health-related outcomes in aging population. However, little is known about the dynamic changing nature of frailty and the potential for it to be modified within the scope of exercise. Currently, there has not been a systematic review of the impact of Otago exercise program (OEP) implementation specifically for the frail or pre-frail older adults. OBJECTIVE: To determine the effectiveness of Otago exercise program on the degree of frailty, physical balance ability, mobility, grip strength and health-related quality of life in older adults with frailty or pre-frailty. METHODS: We conducted literature searching in seven electronic databases, as well as hand-search of reference of included studies from inception to December 2022. Eligible studies included clinical trials of pre-frail or frail elderly receiving OEP interventions reporting on the relevant outcomes. The effect size was evaluated using standardized mean differences (SMDs) and its 95% confidence interval with random effects models. Risk of bias was appraised independently by two authors. RESULTS: 10 trials containing 8 RCTs and 2 non-RCTs studies were included. Five studies were evaluated with some concerns in the evidence quality. The results showed that the OEP intervention could possibly reduce the level of frailty (SMD=-1.14, 95% CI: -1.68â¼-0.06, P < 0.01) and improve the mobility (SMD=-2.15, 95% CI: -3.35â¼-0.94, P < 0.01) and physical balance ability (SMD=2.59, 95% CI: 1.07-4.11), P = 0.01), and enhance their grip strength (SMD=1.68, 95% CI=0.05â¼3.31, P = 0.04). However, no statistically significant effect of OEP on quality of life (SMD=-1.517, 95% CI=-3.18â¼0.15, P = 0.07) in frail elderly was found based on the current evidence. The subgroup analysis indicated that participant age, different intervention total duration and per min of each session have varying degrees of impact on frail or pre-frail older people. CONCLUSIONS: The OEP intervention targeting older adults with frailty or pre-frailty are effective in reducing frailty, improving physical balance ability, mobility, and grip strength with low to moderate certainty. More rigorous and tailored research are still needed in the future to further enrich the evidence in these fields.

BACKGROUND: Circular RNA (circRNA) is considered an important molecular marker for the early diagnosis of tumors and a potential therapeutic target. Herein, we investigated the role and regulatory mechanism of circKDM1B in hepatocellular carcinoma (HCC). METHODS: The expression of circKDM1B, miR-1322 and Protein regulator of cytokinesis 1 (PRC1) mRNA were determined by quantitative real-time polymerase chain reaction (qRT-PCR). Cell counting kit-8 (CCK8) and 5-ethynyl-2'-deoxyuridine (EdU) staining assays were performed to assess cell proliferation activity. Cell migration and invasion were detected by wound-healing scratch and transwell assay. Flow cytometry was used to analyze cell apoptosis. The protein levels of PCNA, MMP9, C-caspase3 and PRC1 were examined using western blot. The binding of circKDM1B and miR-1322 was verified by dual-luciferase reporter assay, RNA immunoprecipitation (RIP) and RNA pull down assay. RESULTS: CircKDM1B was overexpressed in HCC tissues and cells, and its overexpression was related to tumor stage and poor prognosis of HCC patients. Functionally, knockdown of circKDM1B suppressed proliferation, migration, invasion and promoted apoptosis of HCC cells. Mechanistically, circKDM1B functioned as ceRNA of miR-1322 to upregulate PRC1 in HCC cells. Overexpression of miR-1322 inhibited proliferation, migration, invasion and facilitated apoptosis of HCC cells, which was partly reversed by PRC1 overexpression. CircKDM1B knockdown impeded HCC tumor growth in vivo. CONCLUSION: CircKDM1B played a critical role in HCC progression by regulating cell proliferation, migration, invasion and apoptosis. CircKDM1B/miR-1322/PRC1 axis might be a novel therapeutic target of HCC patients.

BACKGROUND: Human Respiratory Syncytial Virus (RSV) infections pose a significant risk to human health worldwide, especially for young children. Whole genome sequencing (WGS) provides a useful tool for global surveillance to better understand the evolution and epidemiology of RSV and provide essential information that may impact on antibody treatments, antiviral drug sensitivity and vaccine effectiveness. OBJECTIVES: Here we report the development of a rapid and simplified amplicon-based one-step multiplex reverse-transcription polymerase chain reaction (mRT-PCR) for WGS of both human RSV-A and RSV-B viruses. STUDY DESIGN: Two mRT-PCR reactions for each sample were designed to generate amplicons for RSV WGS. This new method was tested and evaluated by sequencing 206 RSV positive clinical samples collected in Australia in 2020 and 2021 with RSV Ct values between 10 and 32. RESULTS: In silico analysis and laboratory testing revealed that the primers used in the new method covered most of the currently circulating RSV-A and RSV-B. Amplicons generated were suitable for both Illumina and Oxford Nanopore Technologies (ONT) NGS platforms. A success rate of 83.5% with a full coverage for the genome of 98 RSV-A and 74 RSV-B was achieved from all clinical samples tested. CONCLUSIONS: This assay is simple to set up, robust, easily scalable in sample preparation and relatively inexpensive, and as such, provides a valuable addition to existing NGS RSV WGS methods.

PURPOSE: Currently, the choice of contralateral prophylactic mastectomy (CPM) for breast cancer patients is variable and controversial. Breast cancer patients must make complex and rapid decisions based on the benefits and risks of CPM. Although there are many qualitative studies on the decision-making experiences of breast cancer patients, there is a lack of synthesis of these qualitative studies. Our study goals were to conduct a meta-synthesis of qualitative studies on the decision-making experiences, real-life experiences, psychological feelings and needs of breast cancer patients in CPM decision-making, with the aim of providing information to support the development of CPM practice decisions. METHODS: Using a meta-ethnographic approach, qualitative research studies were analysed and synthesised using the method of "reciprocal translational analysis", and themes related to the decision-making experiences of breast cancer patients with respect to CPM were identified. RESULTS: Five hundred ninety-three documents were retrieved. This meta-synthesis ultimately collected 8 studies. Four themes were identified: (1) decision motivations for survival and body intention; (2) negative and vacillating decision emotions; (3) diverse but weak decision support; (4) short-term satisfaction but long-term unknown and differentiated decision effects. CONCLUSIONS: We found that although patients had different feelings about the effects of CPM in detail, most patients were satisfied with the short-term effects of CPM, but the long-term effects of CPM were still unknown. The study protocol was registered with PROSPERO (International prospective register of systematic reviews) in May 2022 (Registration number: CRD42022334260).

BACKGROUND: Influenza circulated at historically low levels during 2020/2021 due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic travel restrictions. In Australia, international arrivals were required to undergo a 14-day hotel quarantine to limit new introduction of SARS-CoV-2. METHODS: We usedtesting data for travelers arriving on repatriation flights to Darwin, Australia, from 3 January 2021 to 11 October 2021 to identify importations of influenza virus into Australia. We used this information to estimate the risk of a case exiting quarantine while still infectious. Influenza-positive samples were sequenced, and cases were followed up to identify transmission clusters. Data on the number of cases and total passengers were used to infer the risk of influenza cases exiting quarantine while infectious. RESULTS: Despite very low circulation of influenza globally, 42 cases were identified among 15 026 returned travelers, of which 30 were A(H3N2), 2 were A(H1N1)pdm09, and 10 were B/Victoria. Virus sequencing data identified potential in-flight transmission, as well as independent infections prior to travel. Under the quarantine strategy in place at the time, the probability that these cases could initiate influenza outbreaks in Australia neared 0. However, this probability rose as quarantine requirements relaxed. CONCLUSIONS: Detection of influenza virus infections in repatriated travelers provided a source of influenza viruses otherwise unavailable and enabled development of the A(H3N2) vaccine seed viruses included in the 2022 Southern Hemisphere influenza vaccine. Failure to test quarantined returned travelers for influenza represents a missed opportunity for enhanced surveillance to better inform public health preparedness.

Purpose: This study aims to explore the complicated decision-making dilemma and challenges confronted by parents of children suffering from severe asthma within the Pediatric Intensive Care Unit (PICU) when participating in the development of their children's discharge care plans. Patients and Methods: Employing a phenomenological methodology, a purposive sampling was performed to engage with 17 parents who participated in in-depth and semi-structured interviews between October 2022 and February 2023. The transcripts of these interviews were transcribed into textual data, which was then subjected to Colaizzi's seven-step analysis for meticulous coding and comprehensive thematic elucidation. Results: The comprehensive analysis of the factors involved in the intricate decision-making dilemmas faced by parents of children with severe asthma during the process of crafting discharge care plans in the PICU revealed five themes and eight sub-themes: 1) Complexity of asthma-related information; 2) Insufficient provision of comprehensive decision-making support; 3) Encountering negative emotions and wavering confidence; 4) Navigating realistic constraints impacting both parents and HCPs; 5) Balancing the advantages and disadvantages of various plans. Conclusion: Parents of children with severe asthma in the PICU encounter intricate and multifaceted decision-making dilemmas while engaging in the formulation of discharge care plans. These complexities significantly dampen their decision-making enthusiasm and introduce potential risks to the children's prognosis and recovery. In the future, it is imperative to leverage the guidance provided by healthcare professionals (HCPs) in the decision-making process, develop tailored decision support tools specifically designed for the formulation of discharge care plans for children with severe asthma in the PICU.
