Trismus in head and neck cancer: translation and validation of the Chinese version of the Gothenburg Trismus Questionnaire-2 (C-GTQ-2).

OBJECTIVES: Trismus, marked by restricted mouth opening, significantly affects patients with temporomandibular disorder (TMD) and head and neck cancer (HNC). Despite its prevalence, specialized questionnaires for trismus assessment are scarce. This study aims to fill this gap by translating and validating the Gothenburg Trismus Questionnaire version 2 (GTQ-2) into Chinese (C-GTQ-2), enhancing the evaluation of trismus in HNC and TMD patients. MATERIALS AND METHODS: The study involved 78 HNC patients, 75 TMD patients, and a control group of 150 individuals without trismus symptoms. Participants were asked to complete the C-GTQ-2 and other health-related quality of life (HRQL) instruments. A subset of 30 individuals retook the questionnaire within two weeks to assess test-retest reliability. RESULTS: The C-GTQ-2 demonstrated remarkable reliability, with Cronbach's alpha values exceeding 0.70 in three of the four domains, indicating high internal consistency. The instrument also showcased high intra-class correlations in the test-retest, affirming its reliability. Furthermore, it exhibited strong convergent validity, aligning well with other HRQL instruments, and effectively discriminated between patients with and without trismus, establishing its discriminant validity. CONCLUSIONS: The C-GTQ-2 emerges as a valid and reliable tool for assessing trismus in HNC and TMD patients, promising to significantly enhance both clinical and research approaches to managing trismus-related complications in the Chinese-speaking demographic. CLINICAL RELEVANCE: C-GTQ-2 proves effective for trismus assessment in head and neck cancer and temporomandibular disorder patients, offering enhanced clinical and research utility.

Effects of Human Leukocyte Antigen DRB1 Genetic Polymorphism on Anti-Cyclic Citrullinated Peptide (ANTI-CCP) and Rheumatoid Factor (RF) Expression in Rheumatoid Arthritis (RA) Patients.

Rheumatoid arthritis (RA) is a systemic disease characterized by non-infectious inflammation of the joints and surrounding tissues, which can cause severe health problems, affect the patient's daily life, and even cause death. RA can be clinically diagnosed by the occurrence of blood serological markers, rheumatoid factor (RF) and anti-cyclic citrullinated peptide antibody (anti-CCP). However, about 20% of RA patients exhibit negative results for both markers, which makes RA diagnosis difficult and, therefore, may delay the effective treatment. Previous studies found some evidence that human leukocyte antigen (HLA)-related genes might be the susceptibility genes for RA and their polymorphisms might contribute to varieties of susceptibility and disease severity. This study aimed for the genetic polymorphisms of the RA patient genome and their effects on the RA patient's serological makers, RF and anti-CCP. A total of 4580 patients' electronic medical records from 1992 to 2020 were retrieved from the China Medical University Hospital database. The most representative single-nucleotide polymorphisms (SNPs) were identified through a genome-wide association study (GWAS) followed by enzyme-linked immunosorbent assay (ELISA) validation using the blood from 30 additional RA patients. The results showed significant changes at the position of chromosome 6 with rs9270481 being the most significant locus, which indicated the location of the HLA-DRB1 gene. Further, patients with the CC genotype at this locus were more likely to exhibit negative results for RF and anti-CCP than those with the TT genotype. The C allele was also more likely to be associated with negative results for RF and anti-CCP. The results demonstrated that a genetic polymorphism at rs9270481 affected the expression of RF and anti-CCP in RA patients, which might indicate the necessity to develop a personalized treatment plan for each individual patient based on the genetic profile.

[Nursing Experience of Using Caring Theory in Caring for an Patient in Isolation Facing Bereavement].

A nursing experience using caring theory to care for the grief experienced by a patient with COVID-19 during their period of isolation from June 4 to June 15, 2021 is described in this article. The patient was assessed using physical, psychological, social, and spiritual framework assessments. Data were collected using care, observation, interviews, and medical records. The healthcare problems were identified as inefficient breathing patterns, anxiety, and grief. The patient transmitted COVID-19 to her father, who subsequently died of related respiratory failure. During the nursing process, we used a mobile application (app) to provide the patient with information about novel coronavirus pneumonia to relieve her anxiety. When the patient was physically unwell, we delivered drugs and oxygen, and provided comfortable prone position and breathing training to resolve her low-efficiency breathing patterns. Also, we cooperated with the psychological and spiritual team to resolve the patient's psychological problems, used hand-painted illustrations and words to provide encouragement, and provided information on the hospital's funeral services provider to help complete her father's funeral arrangements to reduce her sense of grief. It is suggested that, in the clinical care of similar patients, nurses should pay more attention to their psychological problems. In addition, nurses may use the concepts of caring theory to integrate a holistic approach, provide patient-specific resources, and accompanying the patient through the process of grief. This nursing experience may be used as a reference in the future care of similar patients to improve the quality of clinical nursing care.

Genetic and Functional Effects of Adiponectin in Type 2 Diabetes Mellitus Development.

Diabetes mellitus (DM) is a common chronic metabolic disease, and the C57BLKsJ-db/db mice are good animal models for type 2 diabetes mellitus (T2DM). In this study, Western blotting and immunohistochemistry (IHC) were employed to examine the protein expression of adiponectin in the liver tissues of T2DM mice with different disease courses (4, 16, and 32 weeks). Adiponectin expression reduced in the liver tissues of T2DM mice in different disease courses. The genotypic and allelic frequencies of the adiponectin gene rs1063538 and rs2241766 single nucleotide polymorphisms (SNPs) in a Taiwanese population (570 T2DM patients and 1700 controls) were investigated. Based on the genetic distribution of the rs2241766 locus, the distribution frequency of the T allele in the T2DM group (72.8%) was higher than in the control group (68.8%). Individuals carrying the G allele had a 0.82-fold greater risk of developing T2DM than individuals carrying the T allele. Differences were evident in the genotypic and allelic distributions (p < 0.05). Enzyme-linked immunosorbent assay (ELISA) was used to measure changes in serum adiponectin protein concentrations in the healthy population and in patients with T2DM. Serum adiponectin concentration in patients with T2DM was lower than in the control group. In summary, adiponectin was determined to be a T2DM susceptibility gene and may be involved in T2DM progression.

Genome-wide association study of hyperthyroidism based on electronic medical record from Taiwan.

Excess thyroid hormones have complex metabolic effects, particularly hyperthyroidism, and are associated with various cardiovascular risk factors. Previous candidate gene studies have indicated that genetic variants may contribute to this variable response. Electronic medical record (EMR) biobanks containing clinical and genomic data on large numbers of individuals have great potential to inform the disease comorbidity development. In this study, we combined electronic medical record (EMR) -derived phenotypes and genotype information to conduct a genome-wide analysis of hyperthyroidism in a 35,009-patient cohort in Taiwan. Diagnostic codes were used to identify 2,767 patients with hyperthyroidism. Our genome-wide association study (GWAS) identified 44 novel genomic risk markers in 10 loci on chromosomes 2, 6, and 14 (P < 5 × 10-14), including CTLA4, HCP5, HLA-B, POU5F1, CCHCR1, HLA-DRA, HLA-DRB9, TSHR, RPL17P3, and CEP128. We further conducted a comorbidity analysis of our results, and the data revealed a strong correlation between hyperthyroidism patients with thyroid storm and stroke. In this study, we demonstrated application of the PheWAS using large EMR biobanks to inform the comorbidity development in hyperthyroidism patients. Our data suggest significant common genetic risk factors in patients with hyperthyroidism. Additionally, our results show that sex, body mass index (BMI), and thyroid storm are associated with an increased risk of stroke in subjects with hyperthyroidism.

Ameliorative effects of functional chalaza hydrolysates prepared from protease-A digestion on cognitive dysfunction and brain oxidative damages.

Our patented protease A-digested crude chalaza hydrolysates (CCH) show antioxidant abilities in vitro. The prophylactic effects of CCH on cognitive dysfunction and brain oxidative damages were investigated via a D-galactose (DG)-injected mouse model in this study. Fifty-four mice were randomly divided into the following: (1) CON, 0.1 mL 0.9% saline (subcutaneous injection [SC] on the back)+distilled water (oral gavage); (2) DG, 100 mg/kg BW/day D-galactose (Bio-Serv Co., Flemington, NJ, USA) (SC on the back)+distilled water (oral gavage); (3) DG_LCH, 100 mg/kg BW/day D-galactose (SC on the back) + 50 mg CCH/kg BW/day in 0.1 ml distilled water (oral gavage); (4) DG_MCH, 100 mg/kg BW/day D-galactose (SC on the back) + 100 mg CCH/kg BW/day (oral gavage); (5) DG_HCH, 100 mg/kg BW/day D-galactose (SC on the back) + 200 mg CCH/kg BW/day (oral gavage); (6) DG_AG, 100 mg/kg BW/day D-galactose (SC on the back) + 100 mg aminoguanidine hydrochloride/kg BW/day (oral gavage). The experiment lasted for 84 D. CCH, containing antioxidant-free amino acids and anserine, restored (P < 0.05) DG-injected memory injury in the Morris water maze test and attenuated the neuronal degenerations and nucleus shrinkages in the dentate gyrus area. CCH supplementation also reduced amyloid ß-peptide protein levels and accumulation of advanced glycation end products (AGE) in the brain of DG-injected mice, whereas the brain antioxidant capacity was reversed (P < 0.05) by supplementing CCH. Furthermore, AGE receptor (RAGE), NFκb, IL-6, and TNF-α gene expressions were downregulated (P < 0.05) by supplementing CCH. Therefore, CCH show prophylactic effects on the development of oxidative stress-induced cognitive dysfunction.

Long-term outcomes of graves disease in children treated with anti-thyroid drugs.

BACKGROUND: Graves disease (GD) is the most common cause of thyrotoxicosis in children and adolescents, accounting for 15% of all thyroid diseases during childhood. Anti-thyroid drugs (ATD) are recommended as the first-line treatment in children and adolescents. However, the remission rate is lower in children than in adults, and the optimal treatment duration and favorable factors associated with remission remain unknown. We aimed to investigate long-term outcomes of pediatric GD patients receiving ATD. METHODS: We retrospectively reviewed medical charts of 396 GD subjects from 1985 to 2017 at MacKay Children's Hospital. Ninety-six patients were excluded from the analyses, including 71 patients followed for less than one year, 6 patients who received radioactive therapy and 19 patients who received surgery. The remaining 300 patients initially treated with ATD and followed up for more than 1 year constituted our study population. RESULTS: The 300 patients comprised 257 (85.7%) females and 43 (14.3%) males. Their median age at diagnosis was 11.6 (range 2.7-17.8) years with 11 patients (3.7%) younger than 5 years. Their median follow-up period was 4.7 (range 1.1-23.9) years. Overall, 122 patients achieved the criteria for discontinuing ATD treatment, and seventy-nine (39.9%) patients achieved remission, with a median follow-up period of 5.3 (range 1.5-20.1) years. Patients in the remission group were more likely to be aged <5 years (remission vs. relapse vs. ongoing ATD; 11.4 vs. 0 vs. 2.6%, P = 0.02), less likely to have a family history of thyroid disease (24.1 vs. 42.1 vs. 52.6%, P = 0.001), and had lower TSH receptor antibody (TRAb) levels (42.8 vs. 53.6 vs. 65.1%, P = 0.02) at the time of diagnosis. CONCLUSION: Long-term ATD remains an effective treatment option for GD in children. Pediatric GD patients aged <5 years, having no family history of thyroid disease and having initial lower TRAb levels were more likely to achieve remission.

Genetic susceptibility to idiopathic membranous nephropathy in high-prevalence Area, Taiwan.

Idiopathic membranous nephropathy (MN) is one common cause of idiopathic nephrotic syndrome in adults; 25% of MN patients proceed to end-stage renal disease. In adults, membranous nephropathy is a lead cause of nephrotic syndrome, with about 75% of the cases idiopathic. Secondary causes include autoimmune disease, infection, drugs and malignancy. Three hypotheses about pathogenesis have surfaced: preformed immune complex, in situ immune complex formation, and auto-antibody against podocyte membrane antigen. Pathogenesis does involve immune complex formation with later deposition in sub-epithelial sites, but definite mechanism is still unknown. Several genes were recently proven associated with primary membranous nephropathy in Taiwan: IL-6, NPHS1, TLR-4, TLR-9, STAT4, and MYH9 . These may provide a useful tool for diagnosis and prognosis. This article reviews epidemiology and lends new information on KIRREL2 (rs443186 and rs447707) polymorphisms as underlying causes of MN; polymorphisms revealed by this study warrant further investigation.

Toll-like receptor 9 SNPs are susceptible to the development and progression of membranous glomerulonephritis: 27 years follow-up in Taiwan.

The purpose of this study was to determine whether toll-like receptors 9 (TLR9) gene polymorphisms (rs352139 and rs352140) were markers of susceptibility to the development and progression of membranous nephropathy (MGN) in Taiwanese patients. The polymorphisms were investigated by polymerase chain reaction in 397 Taiwanese individuals (134 MGN patients and 263 controls). Patients with malignancy, chronic infectious diseases, lupus nephritis, or drug-induced secondary MGN were excluded from the study. Data showed AA genotype at rs352139 SNP or GG genotype at rs352140 SNP may indicate higher risk for MGN (odds ratio [OR] = 1.55; 95% confidence interval [CI] = 1.02-2.35, at rs352139 SNP; OR = 1.57; 95% CI = 1.03-2.39, at rs352140 SNP). However, MGN patients with A-G haplotype were susceptible for decreased creatinine clearance rate and for seriously tubule-interstitial fibrosis. The result suggests for the first time that TLR9 (rs352139 and rs352140) polymorphisms may contribute to the development and progression of MGN.

Inhibitory effects of isoliquiritigenin on the migration and invasion of human breast cancer cells.

INTRODUCTION: Isoliquiritigenin (ISL) is a natural phenolic compound extracted from licorice. Previous studies have shown that ISL is a potent antioxidant with anti-inflammatory and antitumor activities. The anti-invasive activity of ISL was still unclear. The actual causes of death for most breast cancer patients were due to the tumor metastasis. Attenuating the expression of vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMPs) is well known to prevent tumor metastasis. OBJECTIVES: The purpose of this study is to investigate the effects of ISL on VEGF and MMP expression in highly metastatic human breast cancer cell line, MDA-MB-231. RESULTS: ISL reduced the secretions and protein levels of VEGF. The VEGF upstream regulatory protein, hypoxia-inducible factor 1-alpha (HIF-1α), was also reduced after ISL treatment. Moreover, ISL inhibited the expression and gelatinolytic activity of MMP-2 and MMP-9 which were confirmed by western blot and gelatin zymography assay. Additionally, the anti-migratory activity of ISL was further confirmed by chamber migration assay and wound migration assay. Upstream signaling pathways, including the expression of phosphatidylinositol-3 kinase (PI3K), the phosphorylation of p38 and Akt kinase and NF-κB DNA binding activity, were suppressed by ISL. CONCLUSION: These findings suggest that ISL suppresses the migration of MDA-MB-231 cells by inhibiting the upstream signaling pathways.

Association of STAT4 polymorphisms with susceptibility to primary membranous glomerulonephritis and renal failure.

BACKGROUND: Membranous glomerulonephritis (MGN) is one of common causes of idiopathic nephrotic syndrome in adults, and 25% of MGN patients proceed to end-stage renal disease. STAT4 gene polymorphisms have been reported to be associated with many inflammatory diseases. The objective of this study was to clarify the relationship between STAT4 gene polymorphisms and the pathogenesis of MGN. METHODS: We investigated the association of three STAT4 gene polymorphisms (rs3024912, rs3024908, and rs3024877) with the susceptibility to MGN in 403 Taiwanese populations (138 MGN patients and 265 controls). RESULTS: The results indicated that the statistically significant difference in genotype frequency distribution was found at rs3024908 SNP in MGN patients and control groups (p=0.014). In addition, the individuals with the GG genotype at rs3024912 SNP may have a higher risk in kidney failure of MGN patients (adjusted odds ratio [OR]=3.255; 95% confidence interval [CI]=1.155-9.176, p=0.026). CONCLUSIONS: Our data provide a new information that the STAT4 (rs3024912 and rs3024908) polymorphisms may be the underlying cause of MGN, and these polymorphisms revealed by this study warrant further investigation.

Clinical and laboratory characteristics of type 1 diabetes in children and adolescents: experience from a medical center.

BACKGROUND: The incidence of type 1 diabetes (T1D) is increasing rapidly worldwide, predominantly in younger individuals. We developed a checklist of all symptoms of T1D reported in the literature and compared the completeness of the recording of symptoms at initial presentation before and after the checklist was adopted. METHODS: We retrospectively reviewed the records of patients newly diagnosed with T1D from January 1, 1979 through September 30, 2006 to assess the presenting features and test the usefulness of a symptom checklist in evaluating the history on presentation. The checklist was incorporated into the records as of October 1, 1994. RESULTS: Of the 304 patients identified, 130 (43%) had checklists in the charts. There were 146 (48%) boys, 98 (32%) who were diagnosed under the age of 6 years, and 198 (65%) presented with diabetic ketoacidosis (DKA). Records with a checklist noted diabetic symptoms that were subtle and easily ignored more often than records without the checklist. As compared with those diagnosed at an older age, patients diagnosed at < or = 6 years were more likely to be male, have DKA and a shorter symptom duration, and report more episodes of preceding viral infection and dyspnea. Patients with DKA also had a shorter symptom duration. CONCLUSIONS: A diabetic symptom checklist was helpful in identifying clinical diabetic symptoms and signs which were otherwise easily ignored. Younger children were more likely to have a shorter symptom duration and a higher incidence of DKA.

Neonatal meningitis caused by coxsackievirus B5.

Enteroviral infections are more severe in neonates than in older children, and coxsackievirus B is most frequently associated with severe neonatal disease. We summarize the course and clinical data of four neonates with meningitis caused by coxsackievirus B5. Their clinical symptoms and signs were persistent fever, poor appetite, and decreased activity, with vomiting in two. Laboratory analysis of cerebrospinal fluid revealed the following: white blood count, 340-660/mm3; red blood count, 0-250/ mm3; glucose level, 47-59 mg/dl; and total protein level, 70-106 mg/dl. Echocardiography showed normal heart function. Final bacterial cultures of the cerebrospinal fluid showed no growth, whereas viral cultures showed coxsackievirus B5. All patients recovered without intravenous immunoglobulin. No complications occurred at 6-month follow-up.
