RESUMEN

Cardiovascular disease (CVD) is a chronic disease characterized by the accumulation of lipids and fibrous tissue within the arterial walls, potentially leading to vascular obstruction and an increased risk of heart disease and stroke. Hydroxyl radicals play a significant role in the formation and progression of CVD as they can instigate lipid peroxidation, resulting in cellular damage and inflammatory responses. However, precisely detecting hydroxyl radicals in CVD lesions presents significant challenges due to their high reactivity and short lifespan. Herein, we present the development and application of a novel activatable optical probe, Cy-OH-LP, designed to detect hydroxyl radicals in lipid-rich environments specifically. Built on the Cy7 molecular skeleton, Cy-OH-LP exhibits near-infrared absorption and fluorescence characteristics, and its specific response to hydroxyl radicals enables a turn-on signal in both photoacoustic and fluorescence spectra. The probe demonstrated excellent selectivity and stability in various tests. Furthermore, Cy-OH-LP was successfully applied in an in vivo model to detect hydroxyl radicals in mouse models, providing a potential tool for diagnosing and monitoring AS. The biosafety of Cy-OH-LP was also verified, showing low cytotoxicity and no significant organ damage in mice. The findings suggest that Cy-OH-LP is a promising tool for the specific detection of hydroxyl radicals in lipid-rich environments, providing new possibilities for research and clinical applications in the field of oxidative stress-related diseases.

RESUMEN

AIMS: The study investigated the influence of quality of discharge teaching (QDT) on readiness for hospital discharge (RHD) and pathways involved in patients with first-episode stroke, aiming to provide a theoretical framework for enhancing RHD levels and reducing readmission rates. DESIGN: Cross-sectional study. METHODS: A total of 372 inpatients completed the Quality of Discharge Teaching Scale, Readiness for Hospital Discharge Scale, Chronic Disease Self-efficacy Scale and Southampton Stroke Self-Management Questionnaire. Structural equation modelling and Pearson's correlation analysis were utilised to elucidate relationships and action pathways among these variables. RESULTS: The correlation analysis demonstrated significant positive pairwise correlations between QDT, RHD, self-efficacy and self-management (r = 0.376-0.678, p < 0.01). The final model exhibited a good fit with the following indices: χ2/df = 3.286, RMSEA = 0.078, SRMR = 0.0303, GFI = 0.984, AGFI = 0.926, CFI = 0.991 and TLI = 0.970. The impact of QDT on RHD in patients with first-episode stroke was observed through one direct and three indirect pathways: (1) QDT exerted a direct influence on RHD (p < 0.001); (2) QDT indirectly influenced RHD via self-efficacy (p < 0.001); (3) QDT indirectly affected RHD through self-management (p < 0.001); and (4) QDT had an indirect effect on RHD via both self-efficacy and self-management (p < 0.05). CONCLUSION: QDT was found to directly influence RHD in patients with first-episode stroke and also exerted indirect effects through self-efficacy and self-management, either independently or in combination. Early screening of RHD levels in patients before discharge is recommended, along with the enhancement of QDT through the development of tailored guidance plans according to different disease stages, ultimately improving RHD levels and facilitating a safer transition from hospital to home or community. RELEVANCE TO CLINICAL PRACTICE: Healthcare professionals should assess both QDT and RHD levels to provide targeted interventions. The establishment of transitional care teams and implementation of long-term poststroke management are essential for reducing stroke recurrence and mortality rates.

RESUMEN

The control and prevention of ticks and tick-borne diseases rely on chemical insecticides and repellents. Plant-derived compounds potentially represent new and safer repellents. Cinnamaldehyde, a component of cinnamon oil, exhibits antibacterial, anti-inflammatory, acaricidal, and repellent activity against ticks. Here we studied the molecular mechanism of the repellent effect of cinnamaldehyde on Haemaphysalis longicornis. A 2 % cinnamaldehyde treatment resulted in >90 % nymph repellency within 6 h. Nymphs were exposed to cinnamaldehyde for 30 min, and subsequent transcriptome and metabolome analyses revealed the involvement of H. longicornis Acetylcholinesterases (HL-AchEs) in the response process. HL-AchEs was transcribed in all tick developmental stages and tissues. Following cinnamaldehyde treatment, the transcript and specific activity of the enzyme of AchE were significantly altered. Following RNAi, electroantennography (EAG) tests demonstrated a significant decrease in response to various repellents as well as a significant decrease in repellency. Our findings have revealed that HL-AchEs mediates cinnamaldehyde-induced tick repellency, and the results provide insights into the mechanism of plant-derived tick repellents.

RESUMEN

Single-pixel imaging (SPI) using a single-pixel detector is an unconventional imaging method that has great application prospects in many fields to realize high-performance imaging. In particular, the recently proposed catadioptric panoramic ghost imaging (CPGI) extends the application potential of SPI to high-performance imaging at a wide field of view (FOV) with recent growing demands. However, the resolution of CPGI is limited by the hardware parameters of the digital micromirror device (DMD), which cannot meet ultrahigh-resolution panoramic imaging needs that require detailed information. Therefore, to overcome the resolution limitation of CPGI, we propose a panoramic SPI based on rotational subdivision (RSPSI). The key of RSPSI is to obtain the entire panoramic scene by the rotation-scanning of a rotating mirror tilted 45°, so that one single pattern that only covers one sub-FOV with a small FOV can complete an uninterrupted modulation on the entire panoramic FOV during a once-through pattern projection. Then, based on temporal resolution subdivision, the image sequence of sub-FOVs subdivided from the entire panoramic FOV can be reconstructed with pixel-level or even subpixel-level horizontal shifting adjacently. Experimental results using a proof-of-concept setup show that the panoramic image can be obtained with 10428 × 543 of 5,662,404 pixels, which is more than 9.6 times higher than the resolution limit of the CPGI using the same DMD. To the best of our knowledge, the proposed RSPSI is the first to achieve a megapixel resolution via SPI, which can provide potential applications in fields requiring imaging with ultrahigh-resolution and wide FOV.

RESUMEN

Retrons are a class of multigene antiphage defense systems typically consisting of a retron reverse transcriptase, a non-coding RNA, and a cognate effector. Although triggers for several retron systems have been discovered recently, the complete mechanism by which these systems detect invading phages and mediate defense remains unclear. Here, we focus on the retron Ec86 defense system, elucidating its modes of activation and mechanisms of action. We identified a phage-encoded DNA cytosine methyltransferase (Dcm) as a trigger of the Ec86 system and demonstrated that Ec86 is activated upon multicopy single-stranded DNA (msDNA) methylation. We further elucidated the structure of a tripartite retron Ec86-effector filament assembly that is primed for activation by Dcm and capable of hydrolyzing nicotinamide adenine dinucleotide (NAD+). These findings provide insights into the retron Ec86 defense mechanism and underscore an emerging theme of antiphage defense through supramolecular complex assemblies.

RESUMEN

Deep vein thrombosis (DVT) affects vascular health and can even threaten life; however, its pathogenesis remains unclear. Cardiovascular disease (CVD) and DVT share common risk factors, such as dyslipidemia, aging, etc. We aimed to investigate the loci of published CVD susceptibility genes and their association with environmental factors that might be related to DVT. Genotyping by Kompetitive Allele Specific PCR (KASP), collection of lifestyle information, and determination of blood biochemical markers were performed in 165 DVT cases and 164 controls. The impact of six single nucleotide polymorphisms (SNPs) and additional potential variables on DVT morbidity was evaluated using unconditional logistic regression (ULR). To explore the high-order interactions related to genetics and the body's internal environment exposure that affect DVT, ULR, crossover analysis, and multifactor dimensionality reduction/generalized multifactor dimensionality reduction (MDR/GMDR) were employed. Sensitivity analyses were performed using the EpiR package. The polymorphisms of FGB rs1800790 and PLAT rs2020918 were significantly associated with DVT. The optimum GMDR interaction model for gene-gene (G × G) consisted of THBD rs1042579, PLAT rs2020918, and PON1 rs662. The PLAT rs2020918 and MTHFR rs1801133 polymorphisms together eliminated the maximum entropy by the MDR method. The optimum GMDR interaction model for gene-environment (G × E) consisted of MTHFR rs1801133, FGB rs1800790, PLAT rs2020918, PON1 rs662, and total homocysteine (tHcy). Those with high tHcy levels and three risk genotypes significantly increased the DVT risk. In conclusion, certain CVD-related SNPs and their interactions with tHcy may contribute to DVT. These have implications for investigating DVT etiology and developing preventive treatment plans.

RESUMEN

With the rapid development of immunotherapy, therapeutic tumor vaccines, which aim to enhance the immunogenicity of tumor cells and activate the patient's immune system to kill tumor cells, as well as eliminate or inhibit tumor growth, have drawn increasing attention in the field of tumor therapy. However, due to the lack of immune cell infiltration, low immunogenicity, immune escape and other problems, the efficacy of tumor vaccine is often limited. Researchers have developed a variety of strategies to enhance tumor immune recognition, such as improving the immunogenicity of tumor antigens, selecting a suitable vaccine platform, or combining tumor vaccines with other anticancer treatments. In this review, we will deliberate on how to overcome the problem of therapeutic tumor vaccines, and discuss the up-to-date progress and achievements in the tumor vaccine development, as well as their future in cancer treatment.

RESUMEN

Indole is a microbial metabolite produced by the gut microbiota through the degradation of dietary tryptophan, known for its well-established anti-inflammatory and antioxidant properties. In this study, we collected fecal samples from mice fed a high-fat diet (HFD) and those on a standard diet (SD), then conducted 16S rRNA sequencing to analyze their gut microbiota. The analysis revealed distinct differences in the dominant bacterial species between the two groups, with a significant decrease in indole-producing probiotics in the HFD mice compared to the SD group. Then we administered oral indole treatment to male C57BL/6J mice with HFD-induced NAFLD and observed a significant improvement in hepatic steatosis and inflammation. Notably, indole alleviated the HFD-induced decline in serum Angiotensin-(1-7) [Ang-(1-7)] levels and Angiotensin-Converting Enzyme 2 (ACE2) expression. To further investigate the role of indole and ACE2 in NAFLD, we conducted experiments using ACE2 knockout (ACE2KO) mice that were also induced with HFD-induced NAFLD and treated with indole. Interestingly, the protective effects of indole were compromised in the absence of ACE2. In HepG2 cells, indole similarly stimulated ACE2 expression and, in an ACE2-dependent manner, reduced ROS generation, maintained mitochondrial membrane potential stability, and increased SIRT3 expression. In summary, our results highlight the formation of a biologically active gut-liver axis between the gut microbiota and the liver through the tryptophan metabolite indole, which mitigates NAFLD in an ACE2-dependent manner. Elevating dietary tryptophan and increasing indole levels may represent an effective approach for preventing and treating NAFLD.

RESUMEN

Evidence for the treatment of patients with mild-to-moderate chronic obstructive pulmonary disease (COPD) is limited. The efficacy of N-acetylcysteine (an antioxidant and mucolytic agent) for patients with mild-to-moderate COPD is uncertain. In this multicentre, randomised, double-blind, placebo-controlled trial, we randomly assigned 968 patients with mild-to-moderate COPD to treatment with N-acetylcysteine (600 mg, twice daily) or matched placebo for two years. Eligible participants were 40-80 years of age and had mild-to-moderate COPD (forced expiratory volume in 1 second [FEV1] to forced vital capacity ratio <0.70 and an FEV1 ≥ 50% predicted value after bronchodilator use). The coprimary outcomes were the annual rate of total exacerbations and the between-group difference in the change from baseline to 24 months in FEV1 before bronchodilator use. COPD exacerbation was defined as the appearance or worsening of at least two major symptoms (cough, expectoration, purulent sputum, wheezing, or dyspnoea) persisting for at least 48 hours. Assessment of exacerbations was conducted every three months, and lung function was performed annually after enrolment. The difference between the N-acetylcysteine group and the placebo group in the annual rate of total exacerbation were not significant (0.65 vs. 0.72 per patient-year; relative risk [RR], 0.90; 95% confidence interval [CI], 0.80-1.02; P = 0.10). There was no significant difference in FEV1 before bronchodilator use at 24 months. Long-term treatment with high-dose N-acetylcysteine neither significantly reduced the annual rate of total exacerbations nor improved lung function in patients with mild-to-moderate COPD. Chinese Clinical Trial Registration: ChiCTR-IIR-17012604.

RESUMEN

Background: The ryanodine receptor 3 (RYR3) is involved in skeletal muscle contraction by releasing calcium from the sarcoplasmic reticulum and subsequent T-tubule depolarization. It is also expressed in the brain, and variants in the RYR3 gene can lead to congenital myopathy type 20 (MIM: #620310). Methods: We retrospectively analyzed the clinical characteristics and prognosis of a case of West syndrome, developmental and epileptic encephalopathy (DEE) caused by a missense variant in the RYR3 gene. We also reviewed and summarized the literature on epilepsy cases caused by RYR3 gene variants. Results: A 10-month-old female child with delayed psychomotor development and recurrent spasm-like seizures was diagnosed with infantile spasm syndrome and DEE. Treatment with various antiepileptic drugs resulted in initial improvement but ultimately failed to control the seizures. Whole-exome sequencing revealed a novel heterozygous variant c.10943C > T/p.T3648M in the RYR3 gene, and genome-wide sequencing ruled out other potentially pathogenic variants. Three previous reports have described RYR3 variants causing DEE, two of which were attributed to de novo heterozygous variants, and one was a compound heterozygote. Conclusion: The present case of DEE caused by a RYR3 heterozygous variant is consistent with previous rare cases of epilepsy caused by RYR3 gene variants in terms of pathogenesis and clinical features, but significantly different from congenital myopathy type 20. Our findings provide important evidence for the diagnosis of RYR3-related DEE, and we hypothesize that RYR3 gain-of-function variants resulting in "leaky" Ca2+ release channels may be a molecular genetic feature leading to DEE rather than myopathy.

RESUMEN

The development of an affordable, portable, and instrument-free colorimetric biosensor holds significant importance for routine monitoring and clinical diagnosis. To overcome the limitations that traditional monochromatic colorimetric kits struggle to distinguish subtle color changes with the naked eye, we designed and constructed a portable hydrogel kit for polychromatic semi-quantitative and quantitative sensing analysis. When the actual samples and I- were introduced into a gelatin hydrogel encapsulated with MIL-88A(Fe), Au NRs and oxidase (Au@GM88A/I), a noticeable color change occurred. Additionally, a mathematic model between Hue and multicolor signal was set up for the first time by mobile phone photo technology, successfully applied to the glucose detection in serum. The visual detection had a wide concentration range of 0.02-0.80 mM with a limit of detection down to 0.02 mM. Above all, hydrogel kit prepared with gelatin as a carrier addressed the issues of uneven color and slow response rate commonly seen in gels like sodium alginate and agarose. This improvement would be beneficial for enhancing the accuracy of color captured by mobile phone assisted hydrogel kits, making it a valuable tool for biomarker analysis.

RESUMEN

This study systematically evaluated and ranked the efficacy of first- and second-line antibiotics antibiotic options for the clinical management of cellulitis and erysipelas through a network meta-analysis approach. From inception to July 04, 2024, a search for relevant randomized clinical trials (RCTs) was carried out using several databases. Antibiotics including azithromycin, cefaclor, cephalexin, cloxacillin, erythromycin, cephalexin plus trimethoprim-sulfamethoxazole, cephalexin plus placebo, flucloxacillin, clindamycin, ceftriaxone, penicillin, roxithromycin, and pristinamycin were assessed regarding cure rate, the eradication of baseline pathogens, diarrhea or vomiting, and rash. In total, 10 RCTs with 1,936 cellulitis or erysipelas patients were eligible for inclusion. There were no significant differences in the cure rates for cellulitis among the antibiotics analysed, with cefaclor demonstrating the most favorable profile for curative outcomes. In terms of side effects, ceftriaxone was identified as the least likely to induce diarrhea or vomiting. For erysipelas, pristinamycin showed the most promising results in achieving cure rates. Although a comparison of the three antibiotics revealed no significant differences in rash as a side effect in erysipelas, pristinamycin was observed to carry the highest risk for rash. Our findings indicate no significant differences in cure rates among antibiotics for cellulitis. However, ceftriaxone had the fewest gastrointestinal side effects. Pristinamycin showed the highest cure rates for erysipelas but with a higher risk of rash. Future research should focus on optimizing antibiotic selection for cellulitis and erysipelas.

RESUMEN

INTRODUCTION: This study aimed to explore the impact of COVID-19 on strength performance in highly trained athletes. METHOD: A force plate was employed to measure squat jump height (SJH), counter-movement jump height (CMJH), and drop jump reactive strength index (DJRSI) in 27 highly trained athletes before infection, and at one week, two weeks, and four weeks post-recovery. Additionally, an Isometric Mid-thigh Pull (IMTP) test was conducted to record maximum isometric strength (MIS) and the rate of force development of the initial phase (RFD 0-50; RFD 0-100). Repeated measures analysis of variance was utilized to compare variations in these indicators across different time points. RESULTS: One week post-recovery, SJH (-7.71%, P = 0.005), CMJH (-9.08%, P < 0.001), DJRSI (-28.88%, P < 0.001), MIS (-18.95%, P < 0.001), RFD 0-50 (-64.98%, P < 0.001), and RFD 0-100 (-53.65%, P < 0.001) were significantly lower than pre-infection levels. Four weeks post-recovery, SJH (-2.08%, P = 0.236), CMJH (-3.28%, P = 0.277), and MIS (-3.32%, P = 0.174) did not differ significantly from pre-infection levels. However, DJRSI (-11.24%, P = 0.013), RFD 0-50 (-31.37%, P = 0.002), and RFD 0-100 (-18.99%, P = 0.001) remained significantly lower than pre-infection levels. CONCLUSION: After COVID-19, highly trained athletes exhibited a significant reduction in maximum strength, explosive strength, reactive strength, and initial phase force generation capability. By four weeks post-recovery, their maximum and explosive strength had returned to near pre-infection levels, yet their reactive strength and initial phase force generation capability remained significantly impaired.

RESUMEN

Tribovoltaic nanogenerator (TVNG) is an emerging energy device with the advantages of direct current and high power density. At present, many TVNGs are based on single-crystal materials, which are expensive and fragile during structural processing. Here, a polysilicon-based TVNG for bearing in situ rotational speed sensing is developed, which has the same level of performance and lower cost compared to monocrystalline silicon. The defects in polysilicon can provide additional carriers, but the grain boundaries can suppress the transport process of carriers, resulting in almost the same electrical output as single crystals. The oiled sliding mode TVNG has an impressive durability of up to 1 million cycles. The friction coefficient of rolling mode TVNG is as low as 0.14. Based on rolling mode polysilicon TVNG, the tapered roller bearing, thrust ball bearing, and deep groove ball bearing are manufactured by cutting and engraving processes. Moreover, their short-circuit current and open-circuit voltage are linear with speed, and the fitting coefficient is as high as 0.99, providing favorable conditions for in situ rotational speed sensing. This work presents a structure-function integrated bearing design methodology, demonstrating the considerable potential of in situ sensing for intelligent components in the industrial Internet of Things.

RESUMEN

With the advancement of autonomous driving, the industrial demand for 3D object detection has continuously increased, leading to the development of anchor-based LiDAR object detectors reliant on convolutional neural networks (CNN). However, on the one hand, the poor receptive field of CNN limits the understanding of the scene. On the other hand, anchor-based methods cannot accurately predict the posture of objects in the steering. Therefore, in this paper, we propose the voxel self-attention and center-point (VSAC). Firstly, a voxel self-attention network is designed into VSAC to capture extensive voxel relationship. Secondly, considering the impact of feature weight on prediction results, the pseudo spatiotemporal feature pyramid net (PST-FPN) is proposed. Finally, we employ a center-point detection head to make the prediction direction closer to the real object during steering. The experimental results of VSAC on the widely used KITTI dataset, Waymo Open Dataset, and nuScenes dataset demonstrate its positive performance.

RESUMEN

Copper ions, implicated in processes such as oxidative stress and inflammation, are believed to play a crucial role in cardiovascular disease, a prevalent and deadly disease. Despite this, current diagnostic methods fail to detect early stage cardiovascular disease or track copper ion accumulation, limiting our understanding of the disease's progression. Therefore, the development of noninvasive techniques to image copper ions in cardiovascular disease is urgently needed to enhance diagnostic precision and therapeutic strategies. In this study, we report the successful synthesis and application of a copper ion-activated photoacoustic probe, CS-Cu, which exhibits high sensitivity and selectivity toward copper ions both in vitro and in vivo. CS-Cu was able to noninvasively monitor the changes in copper ion levels and differentiate between different mice based on copper ions in urine. Furthermore, the probe demonstrated good photoacoustic stability and exhibited no significant toxicity in the mice. These findings suggest that CS-Cu could be a promising tool for early detection and monitoring of Cu2+ levels in vivo and urine, providing a new perspective on the role of copper ions in cardiovascular disease.

RESUMEN

Background: While sarcopenia has been found to be associated with increased risks of cardiovascular diseases (CVDs), evidence exploring sex-related differences remains insufficient. This study aimed to investigate the differences in how often sarcopenia occurs in each sex, as determined by skeletal muscle area (SMA) in chest CT images, and its association with CVD common risk factors. Methods: This cross-sectional study involved 1,340 inpatients from the Department of Geriatrics of Renji Hospital, affiliated to Shanghai Jiaotong University School of Medicine. Data on age, sex, body mass index (BMI), smoking status, disease history, and clinical parameters were collected. Sarcopenia was defined using chest CT images with a cut-off value of T12-SMA/height2 <25.75 cm2/m2 in male patients and <20.16 cm2/m2 in female patients. Cardiovascular risk was assessed using the Framingham risk score (FRS). The association between T12-SMA/height2-defined sarcopenia and CVD risk factors by sex was evaluated using a multivariate logistic regression analysis. Results: The overall prevalence of T12-SMA/height2-defined sarcopenia (<25.75 cm2/m2 for male patients, <20.16 cm2/m2 for female patients) was 54.03%, with 48.09% in male patients and 63.19% in female patients. The proportion of male patients with high CVD risk was greater than that of female patients. The multivariate analysis revealed that T12-SMA/height2-defined sarcopenia was independently associated with age (in male patients only), systolic blood pressure (SBP), cholesterol, and high-density lipoprotein cholesterol (HDL-C) among the six FRS cardiovascular risk indices. Conclusion: Our results suggest that T12-SMA/height2-defined sarcopenia was more prevalent in male patients than in female patients. Sarcopenia was associated with higher levels of SBP and HDL-C and lower levels of cholesterol. Increasing age had a more significant effect on CVD risk in male patients.

RESUMEN

Computational ghost imaging (CGI) allows two-dimensional (2D) imaging by using spatial light modulators and bucket detectors. However, most CGI methods attempt to obtain 2D images through measurements with a single sampling ratio. Here, we propose a CGI method enhanced by degradation models for under-sampling, which can be reflected by results from measurements with different sampling ratios. We utilize results from low-sampling-ratio measurements and normal-sampling-ratio measurements to train the neural network for the degradation model, which is fitted through self-supervised learning. We obtain final results by importing normal-sampling-ratio results into the neural network with optimal parameters. We experimentally demonstrate improved results from the CGI method using degradation models for under-sampling. Our proposed method would promote the development of CGI in many applications.

RESUMEN

BACKGROUND: Augmentation mentoplasty with implants is an extremely rewarding procedure. Bone resorption is almost unavoidable. The high-risk factors for chin bone resorption have not been explored in the past. This study aimed to analyze and evaluate the factors influencing bone resorption after augmentation mentoplasty with implants using three-dimensional imaging. METHODS: We retrospectively analyzed preoperative craniofacial Computed Tomography scan data from 105 patients who underwent mandibular implantation surgery and 108 patients who did not. We also examined the extent to which different factors influenced the occurrence of bone resorption in the chin area. RESULTS: Patients with silicone gel implants are more prone to bone resorption than those with Medpor implants. Patients who experienced bone resorption had thicker mentalis muscles than those who did not experience bone resorption (6.35 ± 1. mm vs. 5.73 ± 1.25 mm, P < 0.05), and thinner cortical bone (3.25 ± 1.65 mm vs. 5.22 ± 2.04 mm, P < 0.05). Additionally, implants placed above the mandibular bone were more likely to induce bone resorption than those placed below it. CONCLUSIONS: This study is the first to systematically reveal the impact of implant type, placement position, mentalis muscle thickness, and cortical bone thickness on bone resorption after chin augmentation surgery. For patients with thicker mentalis muscles and thinner cortical bones, greater attention should be paid to the occurrence of bone resorption. Choosing silicone implants or placing the implants higher on the mandible can help reduce the occurrence of bone resorption. This study can assist clinicians in selecting appropriate treatment methods, thereby reducing post-implantation bone resorption.

RESUMEN

OBJECTIVE: To evaluate the application of a rehabilitation management protocol for urinary incontinence after robot-assisted laparoscopic prostatectomy (RALP). METHODS: We conducted a retrospective cohort study of 114 patients who underwent RALP between August 2021 and November 2021 as the control group and a prospective analysis of 114 patients who underwent RALP between May 2022 and August 2022 as the experimental group. The rehabilitation management protocol focused on preoperative stage, postoperative care, day of catheter removal, 1 month postoperative, 3 months postoperative, 6 months postoperative, and 12 months or more postoperative. RESULTS: The 24-h pad test was significantly lower in the experimental group compared with the control group at 2 and 6 months after RALP (both P < 0.01). The scores of the international consultation on incontinence questionnaire-short form (ICIQ-SF) in the experimental group were significantly lower than those in the control group at 1 month after RALP (P < 0.01).The scores of quality of life in the experimental group were significantly higher than those of the control group at 1, 2, and 6 months after RALP (all P < 0.01).The scores of Broome Pelvic Muscle Self-efficacy Scale (BPMSES) were lower than those of the control group at 1, 2, 3, and 6 months after RALP (all P < 0.01). CONCLUSION: The application of the rehabilitation management protocol had significant beneficial effects on urinary functions and quality of life in patients with prostate cancer after RALP.
