RESUMEN
PURPOSE: This study aimed to explore the impact of informal care on the health of older adults, providing data to inform the development of informal care systems and social support policies for long-term care services in developing countries. METHODS: Based on data from the 2018 Chinese Longitudinal Healthy Longevity Survey (CLHLS), this study employed the Propensity Score Matching (PSM) method to empirically analyze the effects of informal care on older adults' self-rated health, depression, and anxiety. RESULTS: A total of 4790 older adults were included in the study sample, with 3194 receiving informal care and 1596 not receiving informal care. The results indicated that older adults who received informal care reported better self-rated health and had lower depression and anxiety scores compared to those who did not receive informal care. Among different groups, the positive effects of informal care on physical and mental health were more significant for very old adults, rural residents, and those without a spouse. Informal care had a greater positive impact on the physical health of women and the mental health of men. CONCLUSION: Government agencies should promote effective coordination between informal and formal care through financial support, awareness campaigns, and policy incentives. This will help to accelerate the improvement of the long-term care system and effectively meet the long-term care needs of older adults.
RESUMEN
PURPOSE: To investigate the potential benefit of combining orthokeratology (OK) lenses with 0.05% atropine ophthalmic solution on the efficacy of myopia control in the fast progressors of OK. METHODS: Average axial length (AL) elongation of both eyes in 70 participants using OK lenses alone or OK lenses combined with 0.05 % atropine ophthalmic solution was retrospectively reviewed. During the observation period (phase 1), all participants exhibited an AL elongation that exceeded 0.15 mm over a 6-month period or 0.3 mm over a 12-month period. Subsequently, the participants were divided into two groups: one group received nightly 0.05 % atropine ophthalmic solution in addition to OK lenses for another 1 year (OKA), while the other group continued using OK lenses alone (phase 2). The changes in AL elongation over time and the differences in AL elongation between the two groups were then compared. RESULTS: The baseline and phase 1 demographics and characteristics of the participants was similar between the two groups (all p > 0.05). when considering a one-year timeframe, the OKA group displayed a significantly less AL elongation compared to the OK group (0.14 ± 0.13 mm vs 0.27 ± 0.12 mm, p < 0.001). Within the OKA group, the AL elongation in the second half of the year was significantly faster than in the first half (0.12 ± 0.11 mm vs 0.02 ± 0.14 mm, p = 0.01). Conversely, there was no significant difference in AL elongation between the OK group in the first and second half of the year (0.12 ± 0.07 mm vs 0.15 ± 0.08 mm, p = 0.71). The combination of 0.05 % atropine ophthalmic solution had a significant effect on 1-year AL elongation (p < 0.001). CONCLUSIONS: This study provided preliminary evidence that the combination of OK lenses and 0.05% atropine ophthalmic solution can significantly enhance the effectiveness of myopia control.
RESUMEN
BACKGROUND: Atropine, specifically 0.05% eyedrops, has proven effective in slowing myopia progression. This study aims to investigate peripheral refraction (PR) characteristics in myopic children treated with 0.05% atropine eyedrops at different frequencies. METHODS: One hundred thirty-eight myopic children completed this one-year prospective study, randomly assigned to once daily (7/7), twice per week (2/7), or once per week (1/7) groups. Spherical equivalent (SE) and axial length (AL) were measured. PR was assessed using a custom-made Hartmann-Shack wavefront peripheral sensor, covering a visual field of horizontal 60° and vertical 36°. Relative peripheral refraction (RPR) was calculated by subtracting central from peripheral measurements. RESULTS: After one year, SE increased more significantly in the 1/7 group compared to the 7/7 group (P < 0.001) and 2/7 group (P = 0.004); AL elongation was also greater in the 1/7 group compared to the 7/7 group (P < 0.001). In comparison with higher frequency groups, 1/7 group exhibited more myopic PR in the fovea and its vertical superior, inferior, and nasal retina; and less myopic RPR in the periphery retina after one-year (P < 0.05). Additionally, RPR in the 7/7 group demonstrated myopic shift across the entire retina, the 2/7 group in temporal and inferior retina, while the 1/7 group showed a hyperopic shift in the superior retina (P < 0.05). Moreover, myopic shift of RPR in the temporal retina is related to less myopia progression, notably in the 7/7 group (P < 0.05). CONCLUSIONS: Atropine inhibits myopia progression in a frequency-dependent manner. The once-daily group showed the slowest myopia progression but exhibited more myopic shifts in RPR. Additionally, RPR in the temporal retina was related to myopia progression in all groups. TRIAL REGISTRATION: Chinese Clinical Trial Registry, ChiCTR2100043506.

RESUMEN
Antimicrobial phototherapy has gained recognition as a promising approach for addressing bacterial biofilms, however, its effectiveness is often impeded by the robust physical and chemical defenses of the biofilms. Traditional antibacterial nanoplatforms face challenges in breaching the extracellular polymeric substances barrier to efficiently deliver photosensitizers deep into biofilms. Moreover, the prevalent hypoxia within biofilms restricts the success of oxygen-reliant phototherapy. In this study, we engineered a soft mesoporous organosilica nanoplatform (SMONs) by incorporating polyethylene glycol (PEG), catalase (CAT), and indocyanine green (ICG), forming SMONs-PEG-CAT-ICG (SPCI). We compared the antimicrobial efficacy of SPCI with more rigid nanoplatforms. Our results demonstrated that unique flexible mechanical properties of SPCI enable it to navigate through biofilm barriers, markedly enhancing ICG penetration in methicillin-resistant Staphylococcus aureus (MRSA) biofilms. Notably, in a murine subcutaneous MRSA biofilm infection model, SPCI showed superior biofilm penetration and pharmacokinetic benefits over its rigid counterparts. The embedded catalase in SPCI effectively converts excess H2O2 present in infected tissues into O2, alleviating hypoxia and significantly boosting the antibacterial performance of phototherapy. Both in vitro and in vivo experiments confirmed that SPCI surpasses traditional rigid nanoplatforms in overcoming biofilm barriers, offering improved treatment outcomes for infections associated with bacterial biofilms. This study presents a viable strategy for managing bacterial biofilm-induced diseases by leveraging the unique attributes of a soft mesoporous organosilica-based nanoplatform. STATEMENT OF SIGNIFICANCE: This research introduces an innovative antimicrobial phototherapy soft nanoplatform that overcomes the inherent limitations posed by the protective barriers of bacterial biofilms. By soft nanoplatform with flexible mechanical properties, we enhance the penetration and delivery of photosensitizers into biofilms. The inclusion of catalase within this soft nanoplatform addresses the hypoxia in biofilms by converting hydrogen peroxide into oxygen in infected tissues, thereby amplifying the antibacterial effectiveness of phototherapy. Compared to traditional rigid nanoplatforms, this flexible nanoplatform not only promotes the delivery of therapeutic agents but also sets a new direction for treating bacterial biofilm infections, offering significant implications for future antimicrobial therapies.

Quantifying terrestrial evapotranspiration (ET) and soil moisture dynamics accurately is crucial for understanding the global water cycle and surface energy balance. We present a novel, long-term dataset of global ET and soil moisture derived from the newly developed Simple Terrestrial Hydrosphere model, version 2 (SiTHv2). This ecohydrological model, driven by multi-source satellite observations and hydrometeorological variables from reanalysis data, provides daily global ET-related estimates (e.g., total ET, plant transpiration, soil evaporation, intercepted evaporation) and three-layer soil moisture dynamics at a 0.1° spatial resolution. Validation with in-situ measurements and comparisons with mainstream global ET and soil moisture products demonstrate robust performance of SiTHv2 in both magnitude and temporal dynamics of ET and soil moisture at multiple scales. The comprehensive water path characterization in the SiTHv2 model makes this seamless dataset particularly valuable for studies requiring synchronized water budget and vegetation response to water constraints. With its long-term coverage and high spatiotemporal resolution, the SiTHv2-derived ET and soil moisture product will be suitable to support analyses related to the hydrologic cycle, drought assessment, and ecosystem health.
RESUMEN
Photocatalysis offers a direct, yet robust, approach to eradicate pathogenic bacteria. However, the practical implementation of photocatalytic disinfection faces a significant challenge due to low-efficiency photogenerated carrier separation and transfer. Here, we present an effective approach to improve photocatalytic disinfection performance by exploiting the pyro-phototronic effect through a synergistic combination of pyroelectric properties and photocatalytic processes. A set of comprehensive studies reveals that the temperature fluctuation-induced pyroelectric field promotes photoexcited carrier separation and transfer and thus facilitates the generation of reactive oxygen species and ultimately enhances photocatalytic disinfection performance. It is worth highlighting that the constructed film demonstrated an exceptional antibacterial efficiency exceeding 95% against pathogenic bacteria under temperature fluctuations and light irradiation. Moreover, the versatile modulation role of the pyro-phototronic effect in boosting photocatalytic disinfection was corroborated. This work paves the way for improving photocatalytic disinfection efficiency by harnessing the synergistic potential of various inherent material properties.
RESUMEN
Background: Sleep disorders such as insomnia can lead to a range of health problems. The high risk of side effects and drug abuse of traditional pharmacotherapy calls for a safer non-pharmacotherapy. Aims: To examine the use and efficacy of weighted blankets in improving sleep and related disorders in different populations and explore the possible mechanisms. Methods: A literature search was conducted using PubMed, Embase, Web of Science, MEDLINE, Cochrane Library and CNKI databases. Eligible studies included an intervention with weighted blankets and outcomes covering sleep and/or related disorders (behavioral disturbance, negative emotions and daytime symptoms). Studies using other deep pressure, compression, or exercise-related interventions were excluded. Conclusions: Most of the included studies showed that weighted blankets could effectively improve sleep quality and alleviate negative emotions and daytime symptoms in patients with sleep disorders, attention deficit hyperactivity disorder, autism spectrum disorder, and other related disorders, with a possible mechanism of deep pressure touch. Recommendations: Weighted blankets might be a promising tool for sleep interventions among individuals with sleep disorders in clinical settings. More high-quality and large-scale randomized controlled trials are needed to further validate the safety and efficacy of weighted blankets and explore precise mechanisms.
RESUMEN
Background: Nanovaccines have emerged as a promising vaccination strategy, exhibiting their capacity to deliver antigens and adjuvants to elicit specific immune responses. Despite this potential, optimizing the design and delivery of nanovaccines remains a challenge. Methods: In this study, we engineered a dendritic mesoporous silica-based nanocarrier enveloped in a metal-phenolic network (MPN) layer containing divalent manganese ions and tannic acid (MSN@MT). This nanocarrier was tailored for antigen loading to serve as a nanovaccine, aiming to activate the cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway in dendritic cells (DCs). Our experimental approach encompassed both cellular assays and mouse immunizations, allowing a comprehensive evaluation of the nanovaccine's impact on DC activation and its influence on the generation of antigen-specific T-cell responses. Results: MSN@MT demonstrated a remarkable enhancement in humoral and cellular immune responses in mice compared to control groups. This highlights the potential of MSN@MT to effectively trigger the cGAS-STING pathway in DCs, resulting in robust immune responses. Conclusion: Our study introduces MSN@MT, a unique nanocarrier incorporating divalent manganese ions and tannic acid, showcasing its exceptional ability to amplify immune responses by activating the cGAS-STING pathway in DCs. This innovation signifies a stride in refining nanovaccine design for potent immune activation.

OBJECTIVE: To evaluate the clinical efficacy and safety of 6 to 24â h endovascular therapy (EVT) in patients with wake-up stroke (WUS) with acute large vessel occlusion (LVO) of the anterior circulation guided by noncontrast computed tomography-Alberta stroke program early CT score (NCCT-ASPECTS). METHODS: Fifty-three patients with WUS with acute LVO of the anterior circulation who were treated at the Sir Run Run Shaw Hospital of Zhejiang Medical College from January 2018 to March 2021 were retrospectively analyzed. The patients were divided into NCCT-ASPECTS or CT perfusion groups. Baseline data, perioperative data, and 90-d prognostic information were compared between the two groups. Multivariable logistic regression analysis was used to determine the independent factors influencing outcomes. RESULTS: There were no significant differences in the good prognosis, symptomatic intracranial hemorrhage, and mortality rates between the two groups (P > 0.05). Multivariate logistic regression analysis showed that the puncture-recanalization time was an independent factor for good prognosis. CONCLUSION: Based on NCCT-ASPECTS guidance, EVT in patients with WUS for acute LVO of the anterior circulation within 6 to 24â h may be safe and effective.
RESUMEN
PURPOSE: To investigate how the mounting location of wearable devices affects the measurement of light intensity. METHODS: Two commercially available wearable devices, HOBO and Clouclip, were used to compare the effects of different mount locations on light intensity measurement. We assessed the consistency of the measurements of the two devices by placing a HOBO and a Clouclip simultaneously in 26 different light environments and measuring the light intensity. To simulate the real-life usage scenarios of the two devices, we had 29 participants wear two HOBOs-one on the wrist and the other on the chest-along with a Clouclip on their spectacles for 1 day; meanwhile, the light intensity was measured and analysed. RESULTS: When under the same light environments, the light intensity measured by the Clouclip was 1.09 times higher than that by the HOBO, with an additional 82.62 units (r2=1.00, p<0.001). When simulating the real-life scenarios, the mean light intensity at the eye-level position was significantly lower than that at the chest position (189.13±665.78 lux vs 490.75±1684.29 lux, p<0.001) and the wrist position (189.13±665.78 lux vs 483.87±1605.50 lux, p<0.001). However, there was no significant difference in light intensity between the wrist and chest positions (483.87±1605.50 lux vs 490.75±1684.29 lux, p=1.00). Using a threshold of 1000 lux for outdoor exposure, the estimated light exposure at the eye-level position was significantly lower than that at the chest position (3.9% vs 7.8%, χ2=266.14, p<0.001) and the wrist position (3.9% vs 7.7%, χ2=254.25, p<0.001). CONCLUSIONS: Our findings revealed significant variations in light exposure among the wrist, chest and eye position. Therefore, caution must be exercised when comparing results obtained from different wearable devices.

Purpose: The purpose of this study was to explore two-dimensional peripheral refraction and higher-order aberrations (HOAs) induced by orthokeratology lens decentration. Methods: Two-dimensional peripheral refraction and HOAs in a rectangular field (horizontally 60 degrees and vertically 36 degrees) were obtained using an open-view Hartmann-Shack wavefront sensor. The peripheral field was divided into 8 regions according to a combination of superior (UZ) or inferior (LZ) and a value, 1 (T25 to T30), 2 (T20 to T25), 3 (N20 to N25), or 4 (N25 to N30). The decentration of the lens was evaluated based on the change of power in the front of the tangential corneal map. All measurements were taken at the baseline and 1 month after lens fitting. Results: In total, 134 myopic children (age = 12.47 ± 1.70 years, SER = -2.44 ± 1.10 diopters [D]) were recruited. In general, horizontally asymmetrical change was observed in relative peripheral refraction (RPR), spherical aberration (SA), and horizontal coma. The root-mean square of higher order aberration (RMSHOA) and vertical coma demonstrated radial symmetrical change and vertically asymmetric change, respectively. Relative peripheral myopia was significantly increased after the treatment, with more myopic refraction in the temporal side. RPR changes in UZ2, UZ3, UZ4, LZ1, and LZ2 were related to the amount of lens decentration (r ≈ 0.4, P < 0.05). All HOAs increased after lens fitting (around 0.03 um, 0.02 um, 0.04 um, and 0.41 um for SA, horizontal COMA, vertical COMA, and RMSHOA in the periphery region). Conclusions: RPR and HOAs are related to lens decentration, which might contribute to the efficacy of orthokeratology. Translational Relevance: The study found a decentration-related optical feature after 1 month of lens wear, which is a suggested protective factor in myopia treatment. The findings might provide new insights for customized contact lens myopia treatment based on optics.

OBJECTIVE: To explore and analyze the clinical effect and potential value of a double-capsule fecal catheter device in patients with fecal incontinence in the intensive care unit (ICU). METHODS: A total of 107 patients with fecal incontinence who were admitted to the ICU of the First Affiliated Hospital of Gannan Medical University from May 2017 to April 2023 were selected and randomly divided into the observation group and the control group, with 68 cases in the observation group and 39 cases in the control group. The observation group was given a double-capsule fecal catheter device, and the control group was given an ordinary fecal catheter device for drainage. The clinical baseline data, adverse events, skin conditions, changes of patients' quality of life (QoL), indicators from laboratory test, working pressure and burden of nursing, average length of stay (ALOS) and prognosis of patients were compared between the two groups. RESULTS: There was no significant difference in age, gender, body mass index (BMI), hypertension history, diabetes mellitus history and smoking history between the observation group and the control group (all P>0.05). The occurrence probability of the number of catheter obstructions, perianal leakage, catheter prolapse and the incidence of discomfort reactions in the observation group were significantly lower than those in the control group, and the difference was statistically significant (P<0.01). After the use of the double-capsule fecal catheter device, the skin condition of the patient's perineum and perianal area was significantly improved and remained dry and comfortable for a long time, and the recovery of the primary disease in patients with fecal incontinence was also more optimistic. After application of the double-capsule fecal catheter device, the scores of QoL significantly increased in patients from the observation group (P<0.05). After using the double-capsule fecal catheter device, the levels of WBC, neutrophils count, PCT and IL-6 in the observation group were significantly lower than those in the control group after nursing (P<0.05). However, there was no significant difference in levels of CRP, TNF-α, albumin and prealbumin between the two groups (P>0.05). The responsible nurses of the patients in the control group expressed significantly higher nursing work burden than the observation group (P<0.05). Patients in the observation group had shorter ALOS and lower mortality than those in the control group (P<0.01). CONCLUSION: The application of the novel double-capsule fecal catheter device can reduce the adverse events and working pressure and burden of nursing, it also improved skin condition and patients' QoL. Correspondingly, it improved relevant prognostic indicators during the patient's hospitalization. It has beneficial clinical practicability and popularity for fecal incontinence in patients, and it is worthy of use and promotion.
RESUMEN
OBJECTIVE: To analyze the effects of mangiferin combined with bortezomib on the proliferation, invasion, apoptosis and autophagy of human Burkitt lymphoma Raji cells, as well as the expression of CXC chemokine receptors (CXCRs) family, and explore the molecular mechanism between them to provide scientific basis for basic research and clinical work of Burkitt lymphoma. METHODS: Raji cells were intervened with different concentrations of mangiferin and bortezomib alone or in combination, then cell proliferation was detected by CCK-8 assay, cell invasion ability was detected by Transwell chamber method, cell apoptosis was detected by Annexin V/PI double-staining flow cytometry, apoptosis, autophagy and Akt/mTOR pathway protein expression were detected by Western blot, and the expression changes of CXCR family was detected by real-time quantitative PCR (RT-qPCR). RESULTS: Different concentrations of mangiferin intervened Raji cells for different time could inhibit cell viability in a concentration- and time-dependent manner (r =-0.682, r =-0.836). When Raji cells were intervened by combination of mangiferin and bortezomib, compared with single drug group, the proliferation and invasion abilities were significantly decreased, while the apoptosis level was significantly increased (P <0.01). Mangiferin combined with bortezomib could significantly up-regulate the expression of pro-apoptotic protein Bax and down-regulate the expression of anti-apoptotic protein Bcl-2 after intervention in Raji cells. Caspase-3 was also hydrolyzed and activated, and then induced the apoptosis of Raji cells. Mangiferin combined with bortezomib could up-regulate the expression of LC3â ¡ protein in Raji cells, and the ratio of LC3â ¡/LC3â in cells was significantly up-regulated compared with single drug or control group (P <0.01). Mangiferin combined with bortezomib could significantly inhibit the phosphorylation levels of Akt and mTOR, inhibit the proliferation and invasion of Raji cells by inhibiting Akt/mTOR pathway, and induce cell autophagy and apoptosis. Mangiferin and bortezomib could down-regulate the expressions of CXCR4 and CXCR7 mRNA after single-agent intervention in Raji cells, and the down-regulations of CXCR4 and CXCR7 mRNA expression were more significant when the two drugs were combined (P <0.01). Mangiferin alone or combined with bortezomib had no significant effect on CXCR5 mRNA expression in Raji cells (P >0.05), while the combination of the two drugs could down-regulate the expression of CXCR3 (P <0.05). CONCLUSION: Mangiferin combined with bortezomib can synergistically inhibit the proliferation and invasion of Raji cells, and induce autophagy and apoptosis. The mechanism may be related to the inhibition of Akt/mTOR signaling pathway, down-regulation of anti-apoptotic protein Bcl-2 and up-regulation of pro-apoptotic protein Bax, and the inhibition of the expression of CXCR family.

Background: Inflammatory bowel disease (IBD) is closely related to higher intracellular oxidative stress. Therefore, developing a novel method to scavenge the harmful reactive oxygen species (ROS) and alleviate colon inflammation to treat IBD is a promising strategy. Methods: CeO2@PDA-PEG (CeO2@PP) were synthesized by modifying ceria (CeO2) nanorods with polydopamine (PDA) and polyethylene glycol (PEG). The ROS scavenging ability of CeO2@PP was detected by using flow cytometry and confocal laser scanning microscope (CLSM). The anti-inflammatory ability of CeO2@PP was determined in vitro by treating lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. The biocompatibility of CeO2@PP was evaluated in vivo and in vitro. Moreover, the therapeutic effects of CeO2@PP in vivo were estimated in a dextran sulfate sodium salt (DSS)-induced colitis mouse model. Results: Physicochemical property results demonstrated that PDA and PEG modification endowed CeO2 nanorods with excellent dispersibility and colloidal stability. CeO2@PP maintained superior enzyme-like activity, including superoxide dismutase (SOD) and catalase (CAT), indicating antioxidant ability. Moreover, in vitro results showed that CeO2@PP with PDA promotes LPS-induced RAW 264.7 macrophages into M2-type polarization. In addition, in vitro and in vivo results showed that CeO2@PP have great biocompatibility and biosafety. Animal experiments have shown that CeO2@PP have excellent anti-inflammatory effects against DSS-induced colitis and effectively alleviated intestinal mucosal injury. Conclusion: The nanoplatform CeO2@PP possessed excellent antioxidant and anti-inflammatory properties for scavenging ROS and modulating macrophage polarization, which is beneficial for efficient colitis therapy.

OBJECTIVE: This study explored the role of obstructive sleep apnea (OSA) in post stroke anxiety (PSA) in noncardiogenic ischemic stroke patients. METHODS: 180 patients with noncardiogenic ischemic stroke were consecutively enrolled from January 2019 to December 2019. All patients underwent polysomnography (PSG) to assess for OSA. OSA severity was identified based on the apnea hypopnea index (AHI), i.e., no OSA (AHI <5), mild OSA (5 = AHI <15), and moderate to severe OSA (AHI ≥15). Neuropsychological assessments were performed at acute phase and 6 months later to evaluate anxiety (Chinese version of the Zung self-rating anxiety scale [SAS], and Beck Anxiety Inventory [BAI]), depression (Patient Health Questionnaire-9, [PHQ-9]), and cognition (Mini-mental state examination, [MMSE], and Montreal Cognitive Assessment, [MOCA]). Clinical diagnoses of PSA were made based on interviews and the anxiety scales. The correlations between PSA and OSA were investigated in Logistic regression analysis. RESULTS: The prevalence of acute-phase and 6-month PSA were 27 (15%) and 52 (28.9%) respectively. Moderate to severe OSA and post-stroke depression (PSD) were the influencing factors of acute-phase PSA. 6-Month PSA was not associated with OSA but was associated with acute-phase anxiety, education status and MOCA. Logistic regression analysis including respiratory and sleeping parameters showed that AHI and micro-arousal index contributed to acute-phase PSA. CONCLUSIONS: Acute-phase PSA was associated with OSA severity, potentially through OSA-caused sleep discontinuity. While 6-month PSA was associated with acute-phase anxiety, highlighting the need for integration of screening for and management of OSA and PSA at acute phase.

With the widespread prevalence of drug-resistant pathogens, traditional antibiotics have limited effectiveness and do not yield the desired outcomes. Recently, alternative antibacterial therapies based on ultrasound (US) have been explored to overcome the crisis of bacterial pathogens. Antimicrobial sonodynamic therapy (aSDT) offers an excellent solution that relies on US irradiation to produce reactive oxygen species (ROS) and achieve antibiotic-free mediated antimicrobial effects. In addition, aSDT possesses the advantage of superior tissue penetrability of US compared to light irradiation, demonstrating great feasibility in treating deep infections. Although existing conventional sonosensitizers can produce ROS for antimicrobial activity, some limitations, such as low penetration rate, nonspecific distribution and poor ROS production under hypoxic conditions, result in suboptimal sterilization in aSDT. Recently, emerging nanosonosensitizers have enormous advantages as high-performance agents in aSDT, which overcome the deficiencies of conventional sonosensitizers as described above. Thus, nanosonosensitizer-mediated aSDT has a bright future for the management of bacterial infections. This review classifies the current available nanosonosensitizers and provides an overview of the mechanisms, biomedical applications, recent advances and perspectives of aSDT.
RESUMEN
Introduction: The health issues that afflict middle-aged people and older individuals are a significant factor that affects their quality of life. It is crucial to investigate the impact of health shocks on the subjective wellbeing of this demographic and the mechanisms that underlie this impact to promote healthy aging. Methods: This study utilized data from the China Family Panel Study in 2018 and 2020 to analyze the effects of HSs and their categories on the subjective wellbeing of middle-aged people and older individuals using the propensity score matching difference-in-differences method. Additionally, the study explored the mediating role of social participation. Results: The findings indicate that health shocks, both chronic and acute, diminish the subjective wellbeing of middle-aged people and older adults. Furthermore, these shocks have a more significant negative effect on the subjective wellbeing of individuals aged 60 and above, women in the middle-aged and older demographic, individuals in rural areas who belong to the middle-aged and older age groups, and individuals possessing activities of daily living. The mechanism analysis revealed that health shocks, both chronic and acute, reduce the subjective wellbeing of middle-aged people and older individuals by disrupting partnerships. Discussion: Lowering the possibility of health shocks, the government should build a strong health management system and improve the health insurance system to enable timely treatment for persons suffering from health shocks. Individuals and families should live healthy lives and engage in social activities to avoid health shocks and improve subjective wellbeing.

RESUMEN
Purpose: This study investigated the associations of peripheral iron status with different manifestations of restless legs syndrome (RLS), including leg movements (LMs) on polysomnography (PSG), disease severity, and impact on patients. Patients and Methods: In this cross-sectional study, 108 patients with RLS were enrolled at Sir Run Run Shaw Hospital's Center for Sleep Medicine. Demographic information, disease characteristics, RLS severity, and impact on patients were assessed through a semi-structured questionnaire. Peripheral iron indicators [serum ferritin, iron, and transferrin concentrations; unsaturated iron-binding capacity (UIBC) and total iron-binding capacity (TIBC); transferrin saturation (TSAT)] were measured following PSG to assess sleep stages, respiratory events, microarousals and LM parameters. Data from patients with and without ferritin concentration < 50 µg/L were compared in crude analyses, and Spearman correlations of other iron indicators with RLS data were examined. An ordinal logistic regression model was used to adjust for age, sex, body mass index, years of education, age at the time of RLS onset, prior treatment (yes/no), C-reactive protein (CRP)/hemoglobin level, total sleep time and apnea-hypopnea index. Results: Multivariate analysis showed that periodic LMs during sleep (PLMS) and other LM parameters were significantly associated with a ferritin concentration < 50 µg/L, UIBC, TIBC, and serum transferrin concentration, but not serum iron or TSAT. By contrast, the severity and impact of RLS were not associated with a ferritin concentration < 50 µg/L or other peripheral iron indicators in the multivariate model. Conclusion: In this study, peripheral iron status was associated mainly with motor components (LMs on PSG) rather than sensory components (severity and impact of RLS) after adequately controlling for potential confounders, such as CRP and hemoglobin levels. Commonly used peripheral iron metabolism indicators may therefore not be ideal biomarkers of RLS severity or impact on patients.
RESUMEN
Tonsillectomy is a common, minimally invasive, and relatively safe surgical operation. Although the surgical technology for such minor operations is mature and widely available in most countries worldwide, postoperative adverse complications occur and may be hazardous and fatal. Our article presents the details of a 4-year-old boy who suddenly developed pneumothorax and systemic extensive subcutaneous emphysema after tonsillectomy. He received professional treatment from a multi-disciplinary team (MDT) and timely rescue in our hospital; however, he died tragically. To this end, there is an urgent need to raise clinicians' awareness of the potentially fatal and rare complications that can occur after tonsillectomy.
