RESUMO
INTRODUCTION: Family engagement in care has been advocated to promote recovery for patients with mental health conditions. Attitudes of mental health nurses toward the importance of families influence the way they partner with families in mental healthcare. However, little is known about how mental health nurses engage with families and quality of family-centered care (FCC) perceived by patients and caregivers. The study aimed to examine the mediating effect of family nursing practice on the association between mental health nurses' attitudes toward integrating families into care and quality of FCC perceived by patients with schizophrenia and caregivers. DESIGN: A cross-sectional study was conducted. METHODS: A convenience sample of 143 dyads of patients with schizophrenia and their caregivers and 109 mental health nurses were recruited from inpatient wards at two psychiatric hospitals in Taiwan. Demographic and clinical questionnaires, Families' Importance in Nursing Care-Nurses' Attitudes scale, Family Nursing Practice Scale, and Measure of Process of Care for Adults were used to collect data. Data were analyzed using descriptive statistics, independent-sample t-tests, one-way analysis of variance, Pearson correlation coefficients, paired-sample t-tests, and intraclass correlation coefficient (ICC). Mediation analyses were performed using Hayes' PROCESS macro in SPSS (Model 4) with bootstrapping. RESULTS: Mental health nurses exhibited supportive attitudes toward integrating families into care (Mean = 98.96) and greater perceptions of family nursing practice (Mean = 2.44). The concordances between patients and caregivers on perceived quality of family-centered care were significant (ICC = 0.63-0.77). Attitudes of mental health nurses toward integrating families into care had both the total and direct effects on all domains of quality of FCC perceived by patients and caregivers, respectively. The indirect effects of mental health nurses' attitudes toward integrating families into care on aspects of quality of FCC through family nursing practice were significant for patients (95% bias-corrected bootstrap CI of 0.015-0.053) and caregivers (95% bias-corrected bootstrap CI of 0.004-0.041). The magnitude of the indirect effects was medium to large for patients (ES = 0.209-0.257) and caregivers (ES = 0.148-0.221). CONCLUSION: Family nursing practice partially mediated the association between mental health nurses' attitudes toward integrating families into care and aspects of quality of FCC from perspectives of patients and caregivers. CLINICAL RELEVANCE: Interventions tailoring mental health nurses' practice skills and reciprocity with families have the potential to enhance supportive attitudes of mental health nurses toward working with families and further improve perceived quality of FCC in patient-caregiver dyads in mental healthcare practice.
RESUMO
OBJECTIVES: Multidrug-resistant Pseudomonas aeruginosa (MDR-PA) is a life-threatening infection with limited treatment options. This is the first meta-analysis of recently published data to compare the clinical outcomes of ceftazidime-avibactam (CAZ-AVI) with other antimicrobial agents in treating MDR-PA infections. DESIGN: Systematic review and meta-analysis. DATA SOURCES: PubMed, Embase and the Cochrane Library have been systematically reviewed, for publications in the English language, from database inception to July 2023. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Studies comparing CAZ-AVI outcomes with other antimicrobial agents were included. In-hospital mortality & 30-day mortality were assessed as the main outcomes. DATA EXTRACTION AND SYNTHESIS: Literature screening, data extraction, and the quality evaluation of studies were conducted by two researchers independently, with disagreements resolved by another researcher. The Newcastle-Ottawa Scale was used to assess the bias risk for the included studies. Review Manager V.5.4 was employed for the meta-analysis. RESULTS: The meta-analysis included four retrospective studies, enrolling 1934 patients. The CAZ-AVI group demonstrated significantly lower in-hospital mortality (risk ratio (RR) = 0.60, 95% CI:0.37-0.97, I2 = 74%, p = 0.04) in three studies with 1444 patients and lower 30-day mortality, in 438 patients from three studies (RR = 0.54, 95% CI:0.28-1.05, I2 = 67%, p = 0.07). No significant difference in clinical success, microbiological success, length of hospital, and ICU stay was observed. CONCLUSIONS: This meta-analysis demonstrated that CAZ-AVI treatment significantly lowered in-hospital mortality compared with other antimicrobial agents in MDR-PA infections. However, the analysis only included a few observational studies and high-quality, randomized controlled trials are needed to investigate further the scope of CAZ-AVI in MDR-PA infections.
RESUMO
Due to their exceptional chemical stability in water and high structural tunability, zirconium(IV)-based MOFs (Zr-MOFs) have been considered attractive materials in the broad fields of electrocatalysis. Numerous studies published since 2015 have attempted to utilise Zr-MOFs in electrocatalysis, with the porous framework serving as either the active electrocatalyst or the scaffold or surface coating to further enhance the performance of the actual electrocatalyst. Herein, the roles of Zr-MOFs in electrocatalytic processes are discussed, and some selected examples reporting the applications of Zr-MOFs in various electrocatalytic reactions, including several studies from our group, are overviewed. Challenges, limitations and opportunities in using Zr-MOFs in electrocatalysis in future studies are discussed.
RESUMO
Aims: To explore the efficacy of extracorporeal shockwave therapy (ESWT) in the treatment of osteochondral defect (OCD), and its effects on the levels of transforming growth factor (TGF)-ß, bone morphogenetic protein (BMP)-2, -3, -4, -5, and -7 in terms of cartilage and bone regeneration. Methods: The OCD lesion was created on the trochlear groove of left articular cartilage of femur per rat (40 rats in total). The experimental groups were Sham, OCD, and ESWT (0.25 mJ/mm2, 800 impulses, 4 Hz). The animals were euthanized at 2, 4, 8, and 12 weeks post-treatment, and histopathological analysis, micro-CT scanning, and immunohistochemical staining were performed for the specimens. Results: In the histopathological analysis, the macro-morphological grading scale showed a significant increase, while the histological score and cartilage repair scale of ESWT exhibited a significant decrease compared to OCD at the 8- and 12-week timepoints. At the 12-week follow-up, ESWT exhibited a significant improvement in the volume of damaged bone compared to OCD. Furthermore, immunohistochemistry analysis revealed a significant decrease in type I collagen and a significant increase in type II collagen within the newly formed hyaline cartilage following ESWT, compared to OCD. Finally, SRY-box transcription factor 9 (SOX9), aggrecan, and TGF-ß, BMP-2, -3, -4, -5, and -7 were significantly higher in ESWT than in OCD at 12 weeks. Conclusion: ESWT promoted the effect of TGF-ß/BMPs, thereby modulating the production of extracellular matrix proteins and transcription factor involved in the regeneration of articular cartilage and subchondral bone in an OCD rat model.
RESUMO
BACKGROUND: Urinary concerns increase with age impacting health and quality of life. The aims of this study were to describe: (1) urinary concerns as an age-related change (ARC); (2) the challenges of urinary concerns; (3) adaptation strategies used to manage urinary concerns; and (4) the value of engaging with aging (EWA) as a framework to promote self-management of urinary concerns. METHODS: Data was used from semi-structured interviews with 29 older adults (mean age 77 years). An iterative coding process was used. A codebook was developed based on a-priori themes derived from the EWA framework, our previous publication, and a line-by-line coding of one of the transcripts. As the analysis progressed, additional codes emerged, enriching the codebook. RESULTS: Six themes emerged: (1) the participants' experiences; (2) responses to urinary concerns, (3) adaptation and management strategies; (4) knowledge and understanding of urinary concerns; (5) available capacities and resources; and (6) the impact of the COVID-19 pandemic on urinary concerns. Participants tended to address their urinary concerns by adjusting routines, medication schedules, or diet patterns. They tried to secure restroom locations or use tools or reminders to resolve their urinary concerns. COVID-19 led to increased inconvenience for older adults to engage in outdoor activities due to the closure of public restrooms. CONCLUSIONS: Our in-depth qualitative analysis found that participants developed personalized adjustments to address their needs and abilities to their urinary concerns. These findings offer insights into the individual aging experience, which will further enhance our understanding and advancement of person-centered care.

A two-dimensional zirconium-based metal-organic framework (2D Zr-MOF), ZrBTB (BTB = 1,3,5-tri(4-carboxyphenyl)benzene), is used as a platform to simultaneously immobilize terbium ions and europium ions with tunable ratios on its hexa-zirconium nodes by a post-synthetic modification. The crystallinity, morphology, porosity and photoluminescence (PL) properties of the obtained 2D Zr-MOFs with various europium-to-terbium ratios are investigated. With the energy transfer from the excited BTB linker to the installed terbium ions and the energy transfer from terbium ions to europium ions, a low loading of immobilized europium ions and a high loading of surrounding terbium ions in the 2D Zr-MOF result in the optimal PL emission intensities of europium; this phenomenon is not observable for the physical mixture of both terbium-installed ZrBTB and europium-installed ZrBTB. The role of installed terbium ions as efficient mediators for the energy transfer from the excited BTB linker to the installed europium ion is confirmed by quantifying PL quantum yields. As a demonstration, these materials with modulable PL characteristics are applied for the ratiometric detection of D2O in water, with the use of the stable emission from the BTB linker as the reference. With the strong emission of immobilized europium ions and the good dispersity in aqueous solutions, the optimal bimetal-installed ZrBTB, Eu-Tb-ZrBTB(1 : 10), can achieve the sensing performance outperforming those of the terbium-installed ZrBTB, europium-installed ZrBTB and the physical mixture of both.
RESUMO
BACKGROUND: Nonunion of long bone fractures is a significant complication following surgical fixation, with an incidence ranging from 5% to 10%. Surgical intervention is the standard treatment for nonunions, but it may come with potential complications. Nonoperative approaches, such as Extracorporeal Shockwave Therapy (ESWT), have been advocated as alternatives. METHODS: The retrospective study, conducted between January 2004 and January 2018, 91 patients who underwent ESWT for tibia or femur nonunions were included. Nonunion was defined based on radiographic criteria and clinical symptoms. The nonunion morphology was categorized as hypertrophic, oligotrophic, or atrophic. ESWT was administered using the OssaTron device in a single treatment session. Bony union was defined as the presence of bridging callus over fracture site with more than three-fourths of the circumference in both planes within the 12-month postoperative period. RESULTS: The study included 91 patients, with an overall union rate of 62.6%. Higher healing rate was observed in trophic nonunion(69.9%) than atrophic nonunion(33.3%). Multivariate analysis identified the number of surgeries, maximum fracture gap, and atrophic nonunion as independent factors influencing the risk of fracture nonunion after ESWT. ROC curves were generated for these factors, providing more than one surgical interventions, and fracture gap greater than 3.94 mm as negative predictors of ESWT for long bone nonunions. CONCLUSION: The study's primary findings suggest that ESWT is effective in achieving bony union for nonunions in long bones(62.6%). Despite the overall positive results, the study highlights that atrophic nonunions, larger fracture gaps more than 3.94 mm, and multiple surgeries are associated with poorer outcomes.
RESUMO
Lung squamous cell carcinoma (LUSC) remains a difficult-to-treat disease with a poor prognosis. While prominin-1 (PROM1/CD-133) is largely investigated in a variety of malignancies, the role of prominin-2 (PROM2), the other member of the prominin family, has not been studied in LUSC. Transcriptomic data derived from matched tumor and adjacent non-tumorous lung tissues of LUSC patients were employed to conduct an in-depth analysis of the genetic and epigenetic regulation of prominin genes within LUSC, utilizing bioinformatic approaches. Furthermore, cellular behavior experiments were executed to discern the biological functions of PROM2. It was observed that PROM2, in contrast to PROM1, exhibited significant upregulation and overexpression at both the mRNA and protein levels in LUSC, and this upregulation was correlated with shortened patient survival. Transcriptomic analysis unveiled DNA methylation as an epigenetic regulatory mechanism associated with PROM2 expression. Notably, two transcription factors, CBFB and NRIP1, were identified as potential regulators of PROM2 expression. Subsequent in vitro investigations demonstrated that knocking down PROM2 led to the inhibition of cancer cell migration and the epithelial-to-mesenchymal transition (EMT). In summary, the pronounced upregulation of PROM2 in LUSC patients was linked to an unfavorable prognosis, possibly attributable to its influence on cancer cell migration and EMT. These findings suggest that PROM2 could serve as a promising diagnostic biomarker and therapeutic target in the management of LUSC. Consequently, further research into the mechanistic aspects and potential therapeutic interventions targeting PROM2 is warranted in the clinical context.
RESUMO
PURPOSE: This study was conducted to evaluate the efficacy of bladder outlet surgery in patients with detrusor underactivity (DU) and to identify factors associated with successful outcomes. METHODS: We conducted a retrospective review of men diagnosed with DU in urodynamic studies who underwent bladder outlet surgery for lower urinary tract symptoms between May 2018 and April 2023. The International Prostate Symptom Score (IPSS) questionnaire, uroflowmetry (UFM), and multichannel urodynamic studies were administered. Successful treatment outcomes were defined as either an IPSS improvement of at least 50% or the regaining of spontaneous voiding in patients urethral catheterization prior to surgery. RESULTS: The study included 93 male patients. Men diagnosed with significant or equivocal bladder outlet obstruction (BOO) experienced significant postoperative improvements in IPSS (from 20.6 to 6.0 and from 17.4 to 6.5, respectively), maximum urine flow rate (from 5.0 mL/sec to 14.4 mL/sec and from 8.8 mL/sec to 12.2 mL/sec, respectively) and voiding efficiency (from 48.8% to 86.0% and from 61.2% to 85.1%, respectively). However, in the group without obstruction, the improvements in IPSS and UFM results were not significant. The presence of detrusor overactivity (odds ratio [OR], 3.152; P=0.025) and preoperative urinary catheterization (OR, 2.756; P=0.040) were associated with favorable treatment outcomes. Conversely, an unobstructed bladder outlet was identified as a negative prognostic factor. CONCLUSION: In men with DU accompanied by equivocal or significant BOO, surgical intervention to alleviate the obstruction may enhance the IPSS, quality of life, and UFM results. However, those with DU and an unobstructed bladder outlet face a comparatively high risk of treatment failure. Preoperative detrusor overactivity and urinary catheterization are associated with more favorable surgical outcomes. Consequently, active deobstructive surgery should be considered for patients with DU who are experiencing urinary retention.

RESUMO
The poor outcome of patients with lung adenocarcinoma (LUAD) highlights the importance to identify novel effective prognostic markers and therapeutic targets. Long noncoding RNAs (lncRNAs) have generally been considered to serve important roles in tumorigenesis and the development of various types of cancer, including LUAD. Here, we aimed to investigate the role of ENTPD3-AS1 (ENTPD3 Antisense RNA 1) in LUAD and to explore its potential mechanisms by performing comprehensive bioinformatic analyses. The regulatory effect of ENTPD3-AS1 on the expression of NR3C1 was validated by siRNA-based silencing. The effect of miR-421 on the modulation of NR3C1 was determined by miRNA mimics and inhibitors transfection. ENTPD3-AS1 was expressed at lower levels in tumor parts and negatively correlated with unfavorable prognosis in LUAD patients. It exerted functions as a tumor suppressor gene by competitively binding to oncomir, miR-421, thereby attenuating NR3C1 expression. Transfection of lung cancer A549 cells with miR-421 mimics decreased the expression of NR3C1. Transfection of lung cancer A549 cells with miR-421 inhibitors increased the expression of NR3C1 with lower cellular functions as proliferation and migration via epithelial-mesenchymal transition. In addition, inhibition of ENTPD3-AS1 by siRNA transfection decreased the levels of NR3C1, supporting the ENTPD3-AS1/miR-421/NR3C1 cascade. Moreover, the bioinformatic analysis also showed that ENTPD3-AS1 could interact with the RNA-binding proteins (RBPs), CELF2 and QKI, consequently regulating RNA expression and processing. Taken together, we identified that ENTPD3-AS1 and its indirect target NR3C1 can act as novel biomarkers for determining the prognosis of patients with LUAD, and further study is required.
RESUMO
Combining epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) with an anti- vascular endothelial growth factor (VEGF) agent, bevacizumab or ramucirumab, is indicated for advanced lung adenocarcinoma harboring EGFR mutation. This study aimed to show the real-world data of combination therapy and compare the effectiveness between bevacizumab and ramucirumab in combination with an EGFR-TKI. This retrospective study enrolled 47 patients diagnosed of stage IV lung adenocarcinoma with exon 19 deletion or L858R point mutation, receiving a first-line EGFR-TKI with anti-VEGF agent, including 34 (72%) and 13 (28%) patients receiving bevacizumab and ramucirumab, respectively. The response rate was similar in both groups (p = 0.38). Patients receiving bevacizumab had similar progression free survival (PFS) as those receiving ramucirumab (median PFS: 21.9 vs. 24.2 months, p = 0.4871); similar finding was noted in overall survival (OS) (median OS: 33.5 months vs. not reached, p = 0.4618). Patients receiving ramucirumab experienced a significantly high-grade hypertension compared to those receiving bevacizumab (p = 0.0351). Multivariable Cox regression analysis found independent risk factors for worse PFS included poorer ECOG performance status, multiple (≥3) metastatic sites, brain metastasis, and pleural metastasis/effusion, while the type of anti-VEGF agent was not a risk factor. Pericardial metastasis/effusion was the only one independent risk factor for worse OS. In summary, ramucirumab may have similar effectiveness as bevacizumab in combination with an EGFR-TKI as first line therapy for advanced lung adenocarcinoma harboring susceptible EGFR mutation. Further large-scale registry-based cohort studies may be needed to validate our findings.

Carotid endarterectomy (CEA) involves removal of plaque in the carotid artery to reduce the risk of stroke and improve cerebral perfusion. This study aimed to investigate the utility of assessing pulsatile blood volume and flow during CEA. Using a combined near-infrared spectroscopy/diffuse correlation spectroscopy instrument, pulsatile hemodynamics were assessed in 12 patients undergoing CEA. Alterations to pulsatile amplitude, pulse transit time, and beat morphology were observed in measurements ipsilateral to the surgical side. The additional information provided through analysis of pulsatile hemodynamic signals has the potential to enable the discovery of non-invasive biomarkers related to cortical perfusion.
RESUMO
Sclerosing epithelioid fibrosarcoma (SEF) represents a rare variant of fibrosarcoma primarily arising in the deep soft tissue of the extremities and trunk. The author reported a rare case of SEF emerged primarily in the kidney. Clinically, the patient complained of hematuria. The diagnosis was confirmed by histological examination and immunohistochemical staining of MUC4. Subsequent fluorescence in situ hybridization (FISH) analysis detected the presence of EWSR1 gene rearrangement, further confirming the histological diagnosis. The patient has been alive with 12 months follow-ups after nephrectomy. The disease should be considered in the differential diagnosis for primary renal tumors.
RESUMO
PURPOSE: Benign prostatic obstruction (BPO) is the most common cause of lower urinary tract symptoms among men. GreenLight photoselective vaporization of the prostate (GL-PVP) using a 180-W Xcelerated performance system (XPS) laser is a well-established method for treating BPO-induced voiding symptoms. However, its therapeutic effects on storage symptoms remain unclear. This study aimed to analyze the storage outcomes in patients who underwent 180-W XPS GL-PVP for BPO and to identify outcome predictors. MATERIALS AND METHODS: Patients who underwent 180-W XPS GL-PVP for BPO between May 2018 and May 2021 were retrospectively reviewed. Data on clinical characteristics, prostate volume, preoperative and postoperative International Prostate Symptom Scores (IPSS), and preoperative urodynamic parameters were collected. A favorable storage outcome was defined as ≥50% reduction in the IPSS storage subscore. RESULTS: Ninety-nine male patients were included, with a mean age of 69.4 ± 9.6 years and a baseline prostatic volume of 75.9 ± 33.1 mL. The IPSS total, storage, and voiding subscores significantly decreased after GL-PVP (all p < 0.001). Seventy-two patients achieved favorable storage outcome at 6 months. Multivariate analysis revealed that detrusor underactivity was predictive of unfavorable storage outcomes (p = 0.022), while IPSS voiding-to-storage subscore ratio >1.25 and the presence of detrusor overactivity were predictive of favorable storage outcomes (p = 0.008 and 0.033, respectively). CONCLUSION: 180-W XPS GL-PVP provided excellent outcomes in both voiding and storage lower urinary tract symptoms concomitant with BPO. Preoperative IPSS and multichannel urodynamic parameters including detrusor overactivity and underactivity are valuable predictors of postoperative storage outcomes.

In recent years, green and healthy foods have attracted much attention. Plant-based foods have become an alternative to animal-derived foods. In this study, we used walnut and purple rice as the primary raw materials to produce a fermented plant drink. The process included boiling, mixing, grinding, inoculation, fermentation, and sterilization. We then analyzed the similarities and differences between the resulting walnut and purple rice fermented plant drink and an unfermented walnut and purple rice plant drink, as well as dairy-based yoghurt, in terms of physical chemistry, flavor, and sensory characteristics. We also examined the similarities and differences between the walnut and purple rice fermented plant drink and room-temperature yoghurt. The study results revealed that the walnut and purple rice fermented plant drink exhibited greater viscosity than the walnut and purple rice unfermented plant drink and room-temperature yoghurt. Additionally, the former displayed enhanced stability and recovery ability. Notably, distinguishable differences were observed between the three samples in terms of the presence of unknown volatiles and the umami signal, as indicated by electronic nose/tongue and GC-IMS analyses. The umami flavor of the walnut and purple rice fermented plant drink surpasses that of room-temperature yoghurt, while its taste is less salty than that of the walnut and purple rice plant drink. Despite possessing a weaker aroma than dairy-based yogurt, it is more potent than the walnut and purple rice plant drink. Additionally, its relative abundance of olefins, ketones, and alcohols enhances its unique flavor profile, surpassing both other options. Based on sensory analysis, it can be deduced that walnut and purple rice fermented plant drink has the highest overall acceptance rate.
RESUMO
BACKGROUND: The hypothalamus is a crucial brain region that mediates the effects of insulin and leptin signals on peripheral metabolic functions. Previous research has shown that insulin signals in the hypothalamus act via multiple neuronal circuits and anabolic/catabolic pathways that converge on the vagus nerve and sympathetic fibers to coordinate energy metabolism in peripheral organs. Additionally, neuropeptide FF (NPFF) has been identified as a regulator of feeding behaviors and energy homeostasis in the hypothalamus, but the mechanisms underlying its involvement in metabolic control remain unclear. This study aims to explore the underlying mechanisms of NPFF in modulating metabolic disorders. METHODS: In this study, we investigated the physiological role of NPFF in insulin-related energy homeostasis and metabolic health. First, we evaluated the effects of NPFF and its receptors on central insulin signaling using mouse hypothalamic cell lines and Npffr2-overexpressing mice. To further explore the effects of NPFFR2 on insulin-related metabolic disorders, such as diabetes mellitus, we used Npffr2-deleted mice in combination with the streptozotocin (STZ)-induced type 1 diabetes and high-fat diet/STZ-induced type 2 diabetic mouse models. The impacts of central NPFFR2 were demonstrated specifically through Npffr2 overexpression in the hypothalamic arcuate nucleus, which subsequently induced type 2 diabetes. RESULTS: We found that stimulating NPFFR2 in the hypothalamus blocked hypothalamic insulin activity. Npffr2 deletion improved central and peripheral metabolic symptoms in both mouse models of diabetes mellitus, exerting effects on central and systemic insulin resistance, feeding behaviors, glucose and insulin intolerance, lipid metabolism, liver steatosis, and inflammation of white adipose tissues. The overexpression of ARC Npffr2 augmented the metabolic dysregulation in the mouse model of type 2 diabetes. CONCLUSIONS: Our findings demonstrate that hypothalamic NPFFR2 negatively regulates insulin signaling in the central nervous system and plays an important role in maintaining systemic metabolic health, thereby providing valuable insights for potential clinical interventions targeting these health challenges.
