RESUMO

The high infiltration of tumor-associated macrophages (TAMs) in the immunosuppressive tumor microenvironment prominently attenuates the efficacy of immune checkpoint blockade (ICB) therapies, yet the underlying mechanisms are not fully understood. Here, we investigate the metabolic profile of TAMs and identify S-2-hydroxyglutarate (S-2HG) as a potential immunometabolite that shapes macrophages into an antitumoral phenotype. Blockage of L-2-hydroxyglutarate dehydrogenase (L2HGDH)-mediated S-2HG catabolism in macrophages promotes tumor regression. Mechanistically, based on its structural similarity to α-ketoglutarate (α-KG), S-2HG has the potential to block the enzymatic activity of 2-oxoglutarate-dependent dioxygenases (2-OGDDs), consequently reshaping chromatin accessibility. Moreover, S-2HG-treated macrophages enhance CD8+ T cell-mediated antitumor activity and sensitivity to anti-PD-1 therapy. Overall, our study uncovers the role of blockage of L2HGDH-mediated S-2HG catabolism in orchestrating macrophage antitumoral polarization and, further, provides the potential of repolarizing macrophages by S-2HG to overcome resistance to anti-PD-1 therapy.

RESUMO

Dent disease is a rare renal tubular disease with X-linked recessive inheritance characterized by low molecular weight proteinuria (LMWP), hypercalciuria, and nephrocalcinosis. Mutations disrupting the 2Cl-/1H+ exchange activity of chloride voltage-gated channel 5 (CLCN5) have been causally linked to the most common form, Dent disease 1 (DD1), although the pathophysiological mechanisms remain unclear. Here, we conducted the whole exome capture sequencing and bioinformatics analysis within our DD1 cohort to identify two novel causal mutations in CLCN5 (c.749 G > A, p. G250D, c.829 A > C, p. T277P). Molecular dynamics simulations of ClC-5 homology model suggested that these mutations potentially may induce structural changes, destabilizing ClC-5. Overexpression of variants in vitro revealed aberrant subcellular localization in the endoplasmic reticulum (ER), significant accumulation of insoluble aggregates, and disrupted ion transport function in voltage clamp recordings. Moreover, human kidney-2 (HK-2) cells overexpressing either G250D or T277P displayed higher cell-substrate adhesion, migration capability but reduced endocytic function, as well as substantially altered transcriptomic profiles with G250D resulting in stronger deleterious effects. These cumulative findings supported pathogenic role of these ClC-5 mutations in DD1 and suggested a cellular mechanism for disrupted renal function in Dent disease patients, as well as a potential target for diagnostic biomarker or therapeutic strategy development.

RESUMO

The widespread use of nanoparticles in the food industry has raised concerns regarding their potential adverse effects on human health, particularly in vulnerable populations, including pregnant mothers and fetuses. However, studies evaluating the reproductive and developmental toxicity of food-grade nanomaterials are limited. This study investigated the potential risks of prenatal dietary exposure to food-grade silica nanoparticles (E 551) on maternal health and fetal growth using conventional toxicological and epigenetic methods. The results showed that prenatal exposure to a high-dose of E 551 induces fetal resorption. Moreover, E 551 significantly accumulates in maternal and fetal livers, triggering a hepatic inflammatory response. At the epigenetic level, global DNA methylation is markedly altered in the maternal and fetal livers. Genome-wide DNA methylation sequencing revealed affected mCG, mCHG, and mCHH methylation landscapes. Subsequent bioinformatic analysis of the differentially methylated genes suggests that E 551 poses a risk of inducing metabolic disorders in maternal and fetal livers. This is further evidenced by impaired glucose tolerance in pregnant mice and altered expression of key metabolism-related genes and proteins in maternal and fetal livers. Collectively, the results of this study highlighted the importance of epigenetics in characterizing the potential toxicity of maternal exposure to food-grade nanomaterials during pregnancy.

RESUMO

Objective: We aimed to analyze the risk of cardiac rupture (CR) in aged diabetic patients with acute ST-segment elevated myocardial infarction (STEMI) who were followed up for one month, and analyze its independent risk factors. Methods: A total of 3063 aged patients with first onset STEMI admitted to Beijing Anzhen Hospital from January 2001 to December 2020 were retrospectively included. There were 2020 patients without diabetes mellitus (DM) and 1043 patients with DM. We used propensity scores matching (PSM) method to balance baseline exposure factors between patients with or without DM, and all were divided the DM group (1043 cases) and the non-DM group (1043 cases) after the PSM. The primary outcome was CR (the composite rate of papillary muscle rupture, ventricular septum perforation, free wall rupture), which was diagnosed based on clinical manifestations and/or echocardiographic findings. Kaplan-meier survival analyses and log-rank test was used to evaluate the risk of CR between the two groups, and Cox regression analysis was used to evaluate the independent risk factors for CR. Results: After PSM, the baseline clinical data were similar between the DM and non-DM group (all P>0.05). However, level of glycated hemoglobin was significantly higher in the DM group (P<0.05). During 1 month of follow-up, there were 55 (2.64%) cases of CR, most occurred within 48h after admission (40 cases). Among the 55 cases, 11(0.53%) had papillary muscle rupture, 18(0.86%) had ventricular septum perforation, and 26(1.25%) had free wall rupture. Kaplan-meier survival analyses detected that the DM group was associated with significantly increased risk of CR (3.36% vs. 1.92%, HR=1.532, 95% CI: 1.054-2.346, P=0.030), ventricular septum perforation (1.05% vs. 0.67%, HR=1.464, 95% CI: 1.021-2.099, P=0.038) and free wall rupture (1.63% vs. 0.86%, HR=1.861, 95% CI: 1.074-3.225, P=0.027) than those in the non-DM group. Among the 2031 aged STEMI patients without CR, 144 cases (6.90%, 144/2086) died; and among the 55 patients with CR, 37 cases (1.77%, 37/2086) died due to CR. Therefore, twenty percent (20.44%, 37/181) of death was due to CR. Multivariate Cox regression analysis indicated that DM (HR=1.532, 95%CI: 1.054-2.346), age (HR=1.390, 95%CI: 1.079-1.791), female (HR=1.183, 95%CI: 1.049-1.334), troponin I (HR=1.364, 95%CI: 1.108-1.679), brain natriuretic peptide (HR=1.512, 95%CI: 1.069-2.139), revascularization (HR=0.827, 95%CI: 0.731-0.936) and ß-receptor blocker (HR=0.849, 95%CI: 0.760-0.948) were independent risk factors of CR (all P<0.05). Conclusion: DM as well as a few other factors, are independent determinants of CR. CR is not a rare event among the aged STEMI patients and twenty percent of deaths are due to CR. However, large sample-sized studies are warranted to confirm these findings.

RESUMO

Potentially significant drug candidates often face elimination from consideration due to the lack of an effective method for systemic delivery. The poor solubility of these candidates has posed a major obstacle for their development as oral pills or injectables. Niclosamide, a host-directed antiviral, is a good example. In this study, a nanoformulation technology that allows for the non-covalent formulation of niclosamide with cholic acids was developed. This formulation enables efficient systemic delivery through endocytosis and enterohepatic circulation of bile-acid-coated nanoparticles. The oral bioavailability of niclosamide-delivery nanoparticles (NDNs) was significantly enhanced to 38.3%, representing an eight-fold increase compared with pure niclosamide. Consequently, the plasma concentration of niclosamide for the NDN formulation reached 1179.6 ng/mL, which is 11 times higher than the therapeutic plasma level. This substantial increase in plasma level contributed to the complete resolution of clinical symptoms in animals infected with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). This nanoformulation not only provides an orally deliverable antiviral drug for SARS-CoV-2 with improved pharmaceutical bioavailability, but also offers a solution to the systemic delivery challenges faced by potentially significant drug candidates.

RESUMO

INTRODUCTION: In the Chinese healthcare system, where there is overcrowding in hospitals, especially in tertiary care centres, adoption of same-day discharge (SDD) post-percutaneous coronary intervention (PCI) could potentially lead to significant savings of healthcare resources and costs. This study is a non-inferiority trial examining whether post-PCI SDD is feasible in China. The primary hypothesis is that patient outcomes in post-urgent PCI SDD patients are non-inferior to regular discharge patients. METHODS AND ANALYSIS: Post-Urgent PCI Same-DaY is an investigator-initiated multicentre randomised unblinded clinical non-inferiority trial, with 1:1 centralised randomisation to the SDD or usual care (UC) group. Based on sample size calculations, 1296 patients from at least three hospitals, with mild to moderate myocardial infarction, will be included, and acute coronary syndrome patients will be excluded. All patients will receive UC while patients assigned to the SDD group will be discharged on the same day or within 12 hours post-PCI. The primary outcome is major adverse cardiovascular and cerebrovascular events 30 days after discharge. The secondary outcomes are all-cause mortality, bleeding and access site complications. The outcome rates will be compared between groups with the absolute risk difference with a 95% CI. ETHICS AND DISSEMINATION: The study protocol V.2.0 has been approved on 21 January 2022 by the Ethics Committee of Beijing Anzhen Hospital, Capital Medical University (approval number: 2021 KLSD No. 23). The outcomes of this study will be disseminated through a peer-reviewed journal and presented at international conferences. TRIAL REGISTRATION NUMBER: ChiCTR 2200057065; China Clinical Trial Registration.

RESUMO

AIM: The aim of the study was to explore how families' perceptions of dying patients' prognosis awareness influence families' grief. DESIGN: A cross-sectional design was adopted. METHOD: Data were collected from a survey of family caregivers of deceased patients through a tertiary hospital in Mainland China between October 2018 and April 2021. One question asked about families' perceptions of patients' awareness of their prognosis, and the Chinese Grief Reaction Assessment Form was used to measure grief. A multiple linear regression with control variables was run to test the link. Missing data were handled with multiple imputation. RESULTS: A total of 181 participants were involved in the analyses. After whether the patient received professional end-of-life care in the last days, the place of death and several basic information variables were controlled, families' grief was more intense when they were sure that patients were unaware of the terminal prognosis compared to when they believed that patients were aware or not sure about the patient's awareness. The latter two groups did not differ significantly in grief intensity. CONCLUSION: For Chinese family caregivers in the present study, terminal patients' awareness of their prognosis is more beneficial than harmful to their bereavement adaptation. This raises empirical concerns over the assumption that truth is harmful and the nondisclosure pattern on such a basis. IMPACT: The findings extend knowledge on the outcomes of information disclosure from the perspective of bereaved family caregivers. Meanwhile, it informs services for the dying and the bereaved: When making decisions about prognosis disclosure to terminally ill patients, potential impacts on not only patients but also families need to be fully considered. For families who are sure that the patient was never aware of the prognosis, additional support ought to be provided to address their intense grief reactions. PATIENT OR PUBLIC CONTRIBUTION: Several professional caregivers helped revise the questionnaire.

RESUMO

With the modernization and internationalization of traditional Chinese medicine (TCM), the requirement for quality control has increased. The quality marker (Q-marker) is an important standard in this field and has been implemented with remarkable success in recent years. However, the establishment of Q-markers remains fragmented and the process lacks systematicity, resulting in inconsistent quality control and insufficient correlation with clinical efficacy and safety of TCM. This review introduces four multimodal integrated approaches that contribute to the discovery of more comprehensive and accurate Q-markers, thus aiding in the establishment of new quality control patterns based on the characteristics and principles of TCM. These include the whole-process quality control strategy, chemical-activity-based screening method, efficacy, safety, and consistent combination strategy, and TCM theory-guided approach. Furthermore, methodologies and representative examples of these strategies are described, and important future directions and questions in this field are also proposed.

RESUMO

Enolase 2 (ENO2) has increasingly been documented in multiple cancers in recent years. However, the role of ENO2 in clear cell renal carcinoma (ccRCC) has not been fully explored. In the present study, open-access data were downloaded from The Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO), and the Human Protein Atlas (HPA) databases. All statistical analyses were performed in R and GraphPad Prism 8 softwares. Results showed that ENO2 was overexpressed in ccRCC tissues and cell lines and correlated with worse clinical features and prognosis. In vitro experiments indicated that the inhibition of ENO2 could hamper the malignant behaviors of ccRCC cells. Gene Set Enrichment Analysis showed that epithelial-mesenchymal transition, KRAS signaling, inflammatory response, angiogenesis, hypoxia, and WNT/ß-catenin pathways were upregulated in the ENO2 high-expression group; whereas adipogenesis, DNA repair, and androgen response pathways were downregulated. Immune infiltration analysis indicated that patients with high ENO2 levels might have higher M2 macrophages and lower Î³ß T cells in the tumor microenvironment, which may account to some extent for the worse prognosis of ENO2. Moreover, it was found that patients with low and high ENO2 expression might be more sensitive to PD-1 therapy and CTLA-4 therapy, respectively. In addition, patients with high ENO2 expression showed lower sensitivity to common chemotherapy drugs for ccRCC, including axitinib, cisplatin, gemcitabine, pazopanib, sunitinib, and temsirolimus. Overall, these results suggest that ENO2 is a potential prognosis biomarker of ccRCC and could affect the malignant biological behavior of cancer cells, highlighting its value as a potential therapeutic target.

RESUMO

The research and application of immune checkpoint inhibitors (ICIs) have enormously promoted the progression of tumor treatment. Gradual implementation of ICIs in clinical practice is largely limited as they exert uncontrolled collateral effects on the immune system, such as immune-related adverse events (irAEs); this includes rarely reported glomerular diseases. This study aimed to describe the clinical and pathological manifestation of ICIs-induced glomerular diseases and focused on the mechanism and therapeutic strategy for glomerular diseases associated with ICIs. The data of 53 patients with glomerular diseases related to ICIs were retrieved from the PubMed database. The most frequently reported ICIs-related glomerular diseases were pauci-immune glomerulonephritis (28.3%), podocytopathies (26.4%), and immune-complex glomerulonephritis (18.9%). Moreover, anti-PD1 antibodies were the most commonly used ICIs (71.4%). Most patients receiving ICIs discontinued the treatment (89.4%) and were initiated with steroids (87.2%). Rituximab was also useful in the treatment, especially for renal vasculitis. Rechallenging ICIs could be considered for cancer progression or as salvage therapy, where rechallenging ICI therapy with steroids may be beneficial. We believe the treatment should be personalized based on the degree of renal pathology, serum creatinine (Scr), and tumor progression to obtain a good prognosis.

RESUMO

Coronavirus disease 2019 (COVID-19) is associated with increased morbidity and mortality among kidney transplant recipients (KTRs). The administration of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination is the only reliable strategy to prevent COVID-19 and alleviate the severity of COVID-19 in this particular population. The aim of this article was to evaluate the clinical protection by vaccines (breakthrough infections, deaths, and hospitalizations) in KTRs. There were 135 KTRs with COVID-19 breakthrough infections for whom patient-level data were available in PubMed and Web of Science. There was a male predominance (61.4%), 97 were given the standard vaccination regimen, and 38 received three or four doses of the vaccine. The median age was 59.0 (IQR: 49.0−69.0) years. A total of 67 patients were hospitalized, and 10 patients died. In 72.6% of cases, triple-maintenance immunosuppression was employed. The deceased patients were older than the survivors (p < 0.05); an age over 60 years was a risk factor for death (p < 0.05). The KTRs with booster vaccines had a longer time interval from the last vaccine to COVID-19 infection and lower hospitalization rates than the individuals who received the standard vaccination regimen (33.3% vs. 54.8%, p < 0.05). The hospitalized patients were older than the outpatients (p < 0.05). Among 16,820 fully vaccinated or boosted KTRs from 14 centers, there were 633 breakthrough infections (3.58%) and 73 associated deaths (0.41%). The center-level breakthrough infection rates varied from 0.21% to 9.29%. These findings highlight the need for booster doses for KTRs. However, more research is needed to define the long-term effectiveness and immunogenicity of booster doses and to identify methods to boost the protective response to vaccination in these immunocompromised patients.

RESUMO

Objective: Behavioral intentions to care for patients with infectious diseases are crucial for improving quality of care. However, there have been few studies of the behavioral intentions and factors influencing patient care by clinical nurses during the COVID-19 pandemic. This study aims to explore cognition, attitudes, subjective norms, self-efficacy, and behavioral intentions of clinical nurses while caring for COVID-19 patients and to explore any influencing factors. Method: A cross-sectional survey was conducted of nurses through convenience sampling in southeast China from February 2020 to March 2020. The questionnaire was developed based on the theory of planned behavior and self-efficacy. Results: A total of 774 nurses completed the survey. Of these, 69.12% (535/774) reported positive behavioral intentions, 75.58% (585/774) reported a positive attitude, and 63.82% (494/774) reported having the confidence to care for patients. However, the lack of support from family and friends and special allowance affected their self-confidence. Attitude, self-efficacy, subjective norms, and ethical cognition were significantly positively correlated with behavioral intentions (r = 0.719, 0.690, 0.603, and 0.546, respectively, all P < 0.001). Structural equation model showed that self-efficacy, attitude, ethical cognition, and subjective norms had positive effects on behavioral intentions (ß = 0.402, 0.382, 0.091, and 0.066, respectively, P < 0.01). The total effect of behavioral intentions was influenced by attitude, ethical cognition, self-efficacy, and subjective norms (ß = 0.656, 0.630, 0.402, and 0.157, respectively, P < 0.01). In addition, ethical cognition had a positive mediating effect on behavioral intentions (ß = 0.539, P < 0.001). Conclusion: The study results indicated that attitude, ethical cognition, and self-efficacy were the main factors influencing nurses' behavioral intention. Efforts should be made to improve nurses' attitude and self-efficacy through ethical education and training to increase behavioral intentions to care for patients with infectious diseases, which will improve the quality of nursing care.

RESUMO

PURPOSE: To evaluate the clinical utility of surgical reconstruction of finger pulp defects using a plantar flap derived from the toes, with vascular anastomosis of the toe-finger artery and the plantar-palmar vein of the finger. METHODS: Between April 2018 and November 2020, 29 patients with finger pulp defects underwent treatment via the transplantation of pulp tissue from the second toe, with the plantar vein of the toe and the palmar vein of the finger being anastomosed during this procedure. In addition, an anastomosis of the toe and finger artery and nerve was conducted, with a flap size of 1.0 cm * 0.8 cm-2.3 cm * 4.0 cm being used for such repair. Donor tissue sites were closed without introducing deformities or other complications. RESULTS: In all patients in the present study, flap tissues survived and did not exhibit evidence of vascular crisis over a mean 16.8-month follow-up period (range 8-24 months). After successful skin flap grafting, they exhibited good elasticity and a soft texture. At three months post-surgery, some patients reported partial recovery of touch sensation in the transplanted tissue, while pain recovery was evident in some patients at 4-6 months post-surgery. No deformities or other complications were observed at the donor site, and the ability of patients to walk normally was not impaired. CONCLUSION: The anastomosis of toe plantar flaps with the palmar vein can facilitate the repair of finger pulp injuries without the need to dissect the dorsal vein of the toe, allowing for the suturing of donor tissue sites without causing any deformities or other complications. This surgical approach can easily be conducted with satisfactory clinical outcomes.

RESUMO

Surface-enhanced Raman scattering (SERS) technique has enlarged the application of Raman spectroscopy, and the most crucial problem is the exploration of SERS-active materials. In the paper, a SERS substrate made of helical gold nanoparticles by the directed synthesis of L-glutathione (L-GSH) was proposed. Because of the large surface specific area and the uneven conduction electrons distribution for sharp tips resulted from the complex concave surface and the symmetry breaking structure, The nanostructure has shown an impressive average enhancement factor (EF) of 2.95 × 105 under off-resonant condition. This phenomenon was explained by the experimental results and finite difference time domain (FDTD) method. Finally, the SERS substrates were used to detect thiram on pear with a limit of detection (LOD) of 0.62 mg/kg and R2 of 0.9772. The proposed SERS substrates suggest the potential application of chiral molecules such as amino acids, peptides et al. in the SERS-active materials fabrication.

RESUMO

Background and Objective: Chronic kidney disease (CKD) is an important public health concern. With the decline of renal function, CKD patients gradually progress to end-stage kidney disease and need to undergo dialysis or kidney transplantation to maintain life, bringing a heavy economic burden to the family and society. Therefore, it is necessary to effectively prevent and delay the progression of CKD. Essential trace elements play an indispensable role in CKD, and the objective of this study is to systematically review their benefits in the disease and summarize the risks of their excess. Methods: The keywords "trace elements", "chronic kidney disease", "dialysis", "inflammation", and "fibrosis" and their combinations were used to search for relevant literature published in the PubMed database and Web of Science. We then summarized the role of trace element abnormalities in CKD patients in anemia, oxidative stress, inflammation, and chronic fibrosis, and the risk of their excess. Key Content and Findings: Imbalance of essential trace elements is a common complication of CKD and a risk factor for CKD progression, cardiovascular events, and death. This article reviews the effects of essential trace elements (iron, zinc, selenium, copper, iodine, and manganese) on CKD. We analyze literature and discuss the advantages and disadvantages of various essential trace elements. Conclusions: Research shows CKD patients have an imbalance of essential trace elements, and treatment based on these is an important direction for future exploration. A knowledge of the homeostasis of trace elements is important to improving the prognosis of CKD patients and delaying the progression of the disease.

RESUMO

OBJECTIVE: To investigate the efficacy differences between acyclovir and ganciclovir in the treatment of children with Epstein-Barr virus (EBV)- associated infectious mononucleosis (IM). METHODS: A total of 128 children with EBV-IM who were admitted to our hospital from February 2019 to February 2021 were selected and randomly divided into the acyclovir group (n = 64) and the ganciclovir group (n = 64) according to the random number table method. All the children were given symptomatic treatments such as protecting the liver and reducing fever. On this basis, the acyclovir group was given an intravenous drip of acyclovir, while the ganciclovir group was given an intravenous drip of ganciclovir. The treatment was continued for 7 days. After the treatment, the clinical efficacy, disappearance time of symptoms and signs, related blood routine indexes, EBV-DNA negative conversion rate, and the incidence of adverse reactions during the treatment were compared between the two groups. RESULTS: After treatment, the total effective rate of the ganciclovir group (92.19%) was higher than that of the acyclovir group (73.44%) and the difference was statistically significant (P < 0.05). The disappearance time for the symptoms and signs of angina, fever, lymphadenopathy, hepatomegaly, and splenomegaly in the ganciclovir group was lower than that in the acyclovir group, and the difference was statistically significant (P < 0.05). After treatment, the levels of atypical lymphocyte proportion, lymphocyte proportion, and WBC count in the two groups were lower than those before treatment, the levels in the ganciclovir group were lower than those in the acyclovir group, and the difference was statistically significant (P < 0.05). After treatment, the EBV-DNA negative conversion rate (81.25%) in the ganciclovir group was higher than that in the acyclovir group (60.93%) and the difference was statistically significant (P < 0.05). During treatment, the incidence of adverse reactions in the ganciclovir group was significantly lower than that in the acyclovir group and the difference was statistically significant (P < 0.05). CONCLUSION: In the treatment of children with EBV-IM, the therapeutic effect of ganciclovir is obviously superior to that of acyclovir. Ganciclovir can quickly eliminate the symptoms of angina, fever, enlarged lymph nodes, and other signs in children, can improve abnormal blood indicators, and has a higher negative conversion rate of EBV and less adverse reactions.

RESUMO

AIMS AND OBJECTIVES: To understand the influence of family caregivers' perceptions about patients' dying and death quality on their grief intensity. BACKGROUND: Dying patients and their family caregivers face life-limiting illness together, and they work jointly to negotiate shared understandings and mutual adaptation to losses. DESIGN: Cross-sectional data were collected via an online survey. The manuscript followed the STROBE report guideline. METHODS: Family caregivers of patients who had died within 8-365 days prior were recruited. The Quality of Dying and Death Questionnaire (QDDQ) (translated into Mandarin) and the Chinese Grief Reaction Assessment Form (GRAF) were used to measure the two key variables. Multivariate linear regression was performed to explore the links between the two variables while controlling for potential confounders. RESULTS: Data were collected from 170 bereaved Chinese caregivers, and 150 cases were involved in the analysis. The four-factor structure of the QDDQ was appropriate for Chinese participants. After controlling whether end-of-life care was provided and families' satisfaction with physicians' and nurses' services, regressions revealed that more intense grief of the bereaved caregivers was associated with better symptom control for and worse transcendence of the deceased patient. Moreover, those who believed that the deceased had fulfilled his or her family duties before death experienced less intense grief, and the participant's relationship with the deceased also made a difference. CONCLUSION: Two aspects of patients' dying and death quality perceived by family caregivers, namely symptom control and transcendence, have opposite influences on caregivers' grief intensity.

RESUMO

INTRODUCTION: To improve compliance with voiding diaries in children with primary monosymptomatic nocturnal enuresis (PMNE), a new modified 3-day weekend frequency-volume chart (FVC) was designed, and the compliance and validity of this modified FVC was evaluated by comparing with the International Children's Continence Society (ICCS) recommended voiding diary. METHODS: A total of 1200 patients with PMNE were enrolled in the study from 13 centers in China and were randomly assigned to record this modified FVC or the ICCS-recommended voiding diary. The primary outcome measure was the compliance, assessed by comparing the completing index and the quality score of diaries between two groups. The secondary outcome measure was the validity, evaluated by comparing the constituent of subtypes, micturition parameters and response rate to desmopressin. RESULTS: Among the 1200 participants enrolled in the study, 447 patients completed the ICCS-recommended voiding diary and 469 completed the modified diary. The diurnal completing index and the quality score of the modified FVC group were better than those of the ICCS group. In addition, there was no significant difference between these two groups in the subtype classification, or in the response rate to desmopressin. CONCLUSIONS: The modified FVC could be applied to obtain the voiding characteristics of children with PMNE as the ICCS-recommended voiding diary does and offers a reasonable and better choice for children with PMNE from the unselected population in the future.
