Psychometric properties and cross-cultural adaptation of the Indonesian version of the Brief COPE in a sample of advanced cancer patients.

The Brief COPE Inventory has been proven as acceptable psychometric properties to examine coping strategies among cancer patients. However, most psychometric testing studies have been carried out in Western countries, raising concerns about the properties' relevance and applicability in other cultural contexts. This study aimed to present psychometric properties of the Brief COPE in a sample of patients with advanced cancer in Indonesia. Specifically, we intended to examine the factorial structure and the measure's validity and reliability. This study included 440 patients from the original study who completed the Indonesian version of Brief COPE. We used exploratory factor analysis and confirmatory factor analysis to assess factor structure and evaluate the structural model fit, respectively. Reliability was demonstrated by internal consistency represented by Cronbach's alpha coefficient. The factor analysis identified a 21-items scale with 5-factors (avoidance, religion and acceptance, social support coping, problem solving and distraction). Confirmatory factor analysis demonstrated a good model fit. For the whole scale and its subscales Cronbach's alpha coefficients were acceptable signifying good reliability. Convergent, divergent validity and contrast group comparison were evidenced by significant correlations among subscales and the other instruments used. This study shows that the Indonesian version of Brief COPE is a reliable and valid instrument to measure coping in advanced cancer patients and is ready for use amongst this population in the Indonesian cultural context.

Phosphate transporter PHT1;1 is a key determinant of phosphorus acquisition in Arabidopsis natural accessions.

Phosphorus (P) is a mineral nutrient essential for plant growth and development, but most P in the soil is unavailable for plants. To understand the genetic basis of P acquisition regulation, we performed genome-wide association studies (GWASs) on a diversity panel of Arabidopsis (Arabidopsis thaliana). Two primary determinants of P acquisition were considered, namely, phosphate (Pi)-uptake activity and PHOSPHATE TRANSPORTER 1 (PHT1) protein abundance. Association mapping revealed a shared significant peak on chromosome 5 (Chr5) where the PHT1;1/2/3 genes reside, suggesting a connection between the regulation of Pi-uptake activity and PHT1 protein abundance. Genes encoding transcription factors, kinases, and a metalloprotease associated with both traits were also identified. Conditional GWAS followed by statistical analysis of genotype-dependent PHT1;1 expression and transcriptional activity assays revealed an epistatic interaction between PHT1;1 and MYB DOMAIN PROTEIN 52 (MYB52) on Chr1. Further, analyses of F1 hybrids generated by crossing two subgroups of natural accessions carrying specific PHT1;1- and MYB52-associated single nucleotide polymorphisms (SNPs) revealed strong effects of these variants on PHT1;1 expression and Pi uptake activity. Notably, the soil P contents in Arabidopsis habitats coincided with PHT1;1 haplotype, emphasizing how fine-tuned P acquisition activity through natural variants allows environmental adaptation. This study sheds light on the complex regulation of P acquisition and offers a framework to systematically assess the effectiveness of GWAS approaches in the study of quantitative traits.

Urethral large B-cell urethral lymphoma: A case report and literature review.

OBJECTIVE: We report a case of diffuse large B-cell urethral lymphoma initial presenting with non-healing urethra ulcer. CASE REPORT: A 68-year-old woman presented with a non-healing urethral ulcer accompanied with vulvar pruritus, which failed to medical treatment. Her medical history was unremarkable, lacking fever, weight loss or unexplained fatigue. There were no enlarged lymph nodes or palpable liver or spleen upon physical examination. Pelvic examination revealed an ulcerative lesion arising from the posterior wall of the urethral meatus. Cystourethroscopy showed no bladder involvement. Surgical excision of the urethral ulcer was done and immunohistochemical report showed a diffuse large B-cell lymphoma. Bone marrow needle biopsy and computed tomography were done and the diagnosis of primary diffuse large B-cell urethral lymphoma stage IEA was made. She underwent six cycles of cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab and was free of disease for 51 months. CONCLUSION: This report of urethral lymphoma was presented as a non-healing ulcer initially, which was totally different previous reports, presenting with bleeding, either vaginal or urinary, urinary frequency, dysuria, urine retention and self-perceived mass, suggesting that unhealed ulcer on the perineal area should be promptly evaluated and avoidance of unnecessary delayed therapy for possible curable disease.

Focusing on long-term complications of mid-urethral slings among women with stress urinary incontinence as a patient safety improvement measure: A protocol for systematic review and meta-analysis.

BACKGROUND: There are 3 different types of mid-urethral sling, retropubic, transobturator and single incision performed for women with stress urinary incontinence. Prior studies comparing these three surgeries merely focused on the successful rate or efficacy. But nevertheless, what is more clinically important dwells upon investigating postoperative complications as a safety improvement measure. METHODS: A systematic review via PubMed, Ovid, and the Cochrane Database of Systematic Review and studies were applied based on the contents with clearly identified complications. Selected articles were reviewed in scrutiny by 2 individuals to ascertain whether they fulfilled the inclusion criteria: complications measures were clearly defined; data were extracted on study design, perioperative complications, postoperative lower urinary tract symptoms, postoperative pain, dyspareunia, and other specified late complications. RESULTS: A total of 55 studies were included in the systemic review. Perioperative complications encompassed bladder perforation, vaginal injury, hemorrhage, hematoma, urinary tract infection. There were postoperative lower urinary tract symptoms including urine retention and de novo urgency. Furthermore, postoperative pain, tape erosion/ extrusion, further stress urinary incontinence surgery, and rarely, deep vein thrombosis and injury of inferior epigastric vessels were also reported. CONCLUSIONS: Complications of mid-urethral sling are higher than previously thought and it is important to follow up on their long-term outcomes; future research should not neglect to address this issue as a means to improve patient safety.

Arabidopsis inositol phosphate kinases IPK1 and ITPK1 constitute a metabolic pathway in maintaining phosphate homeostasis.

Emerging studies have suggested that there is a close link between inositol phosphate (InsP) metabolism and cellular phosphate (Pi ) homeostasis in eukaryotes; however, whether a common InsP species is deployed as an evolutionarily conserved metabolic messenger to mediate Pi signaling remains unknown. Here, using genetics and InsP profiling combined with Pi -starvation response (PSR) analysis in Arabidopsis thaliana, we showed that the kinase activity of inositol pentakisphosphate 2-kinase (IPK1), an enzyme required for phytate (inositol hexakisphosphate; InsP6 ) synthesis, is indispensable for maintaining Pi homeostasis under Pi -replete conditions, and inositol 1,3,4-trisphosphate 5/6-kinase 1 (ITPK1) plays an equivalent role. Although both ipk1-1 and itpk1 mutants exhibited decreased levels of InsP6 and diphosphoinositol pentakisphosphate (PP-InsP5 ; InsP7 ), disruption of another ITPK family enzyme, ITPK4, which correspondingly caused depletion of InsP6 and InsP7 , did not display similar Pi -related phenotypes, which precludes these InsP species from being effectors. Notably, the level of d/l-Ins(3,4,5,6)P4 was concurrently elevated in both ipk1-1 and itpk1 mutants, which showed a specific correlation with the misregulated Pi phenotypes. However, the level of d/l-Ins(3,4,5,6)P4 is not responsive to Pi starvation that instead manifests a shoot-specific increase in the InsP7 level. This study demonstrates a more nuanced picture of the intersection of InsP metabolism and Pi homeostasis and PSRs than has previously been elaborated, and additionally establishes intermediate steps to phytate biosynthesis in plant vegetative tissues.

[A preliminary study of the work values of male nurses in Taiwan and related factors].

BACKGROUND: Male nurses account for 1.08% of Taiwan's total professional nursing workforce. While work values are known to impact the practice of female nurses, the work values of male nurses have never been fully evaluated. PURPOSE: The aim of this study was to explore the work values of male nurses in Taiwan and related factors. METHODS: We applied a cross-sectional design that targeted all male nurses nationwide and used a structured questionnaire distributed by mail to collect data. RESULTS: Data were collected from 1,087 Taiwan-based male nurses with 745 valid responses. Mean score for overall work value was 2.78 (on a maximum scale of 4). Socio-demographic differences contributed to work value variance among respondents. Major factors of influence on work value included education, work unit, work position, work rank, salary, hospital classification, and reason for choosing a nursing career. CONCLUSION: This study found personal characteristics, occupational roles, job performance, and reason for choosing a career in nursing to all correlate strongly with work value.

A sesquiterpenol extract potently suppresses inflammation in macrophages and mice skin and prevents chronic liver damage in mice through JNK-dependent HO-1 expression.

This study aimed to elucidate the anti-inflammatory and hepatoprotective bioactivities of a sesquiterpenol, (1S,6R)-2,7(14),10-bisabolatrien-1-ol-4-one (BSL), isolated from Cryptomeria japonica (Taxodiaceae) wood extract. BSL markedly suppressed TNF-α and IL-6 secretion, PGE(2) production, and mRNA expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), in lipopolysaccharide (LPS)-stimulated mouse macrophages. BSL also potently inhibited the 12-O-tetradecanoylphorbol-13-acetate (TPA) induced protein levels of nitrotyrosine and COX-2 in mouse skin with dermatitis. Conversely, the stress protein heme oxygenase-1 (HO-1) was found upregulated in the same BSL-treated macrophages, probably through activation of the JNK-dependent pathway. LPS-induced activation of NF-κB and mitogen-activated protein kinase signaling pathways, however, was not responsive to BSL treatment. A BSL-enriched extract (BSL-E; 10mg/kg) significantly prevented CCl(4)-induced chronic liver injury, lipid accumulation, and cell necrosis and inhibited aminotransferase activities and iNOS and COX-2 overexpression in mice liver tissues, an effect comparable with that of silymarin, a hepatoprotective drug.
