Correlation between coronary heart disease severity and subsequent chronic rhinosinusitis severity: A retrospective cohort study.

Coronary heart disease (CHD) is associated with the development of several diseases. This retrospective population-based cohort study investigated the association between CHD severity and subsequent chronic rhinosinusitis (CRS) of varying severity. We used data from Taiwan's National Health Insurance Research Database. CHD was categorized as severe if treated using a coronary artery bypass graft (CABG) and as mild if treated with percutaneous coronary intervention (PCI). The primary outcome of this study was the development of CRS or severe CRS treated using functional endoscopic sinus surgery. Cox proportional hazards regression was used to calculate adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) for CRS and severe CRS in different patient groups. We included 31,784 patients who received PCI surgery (the CHD-PCI group) and 15,892 patients who received CABG surgery (the CHD-CABG group). A total of 813 and 482 episodes of CRS occurred in the CHD-PCI and CHD-CABG groups, respectively, and 45 and 16 severe CRS events occurred in the CHD-PCI and CHD-CABG groups, respectively. Our multivariable analysis demonstrated that the incidence of CRS in the CHD-CABG group was significantly higher than that in the CHD-PCI group (aHR: 1.196, 95% CI: 1.064-1.280, P = 0.0402), but the two groups had similar incidence rates of severe CRS (aHR: 0.795, 95% CI: 0.456-1.388, P = 0.5534). Subgroup analyses revealed that the association between CHD severity and CRS development was more significant among men (P = 0.0016). In conclusion, we determined that severe CHD treated with CABG was associated with a higher incidence of subsequent CRS, and this association was more prominent among men.

Changes in family functioning among primary family caregivers of patients with schizophrenia.

INTRODUCTION: Family functioning, particularly among primary family caregivers for patients with schizophrenia, is a global concern that poses unprecedented challenges. The family unit is a pivotal agent for the preservation of the integrity of individual members. Little attention has been paid to the changes in family functioning and their predictors in primary family caregivers. This study aimed to examine the changes in and the correlates of family functioning in primary family caregivers of individuals with schizophrenia over a 6-month post-discharge period. DESIGN: A prospective, longitudinal study was conducted. METHODS: A total of 58 primary family caregivers of patients with schizophrenia were recruited from two psychiatric hospitals in Taiwan. Data were collected four times, including 1 week before hospital discharge and at 1-, 3-, and 6-month intervals post-discharge. Demographic and clinical questionnaires, the Affiliate Stigma Scale, the Family Empowerment Scale, and the General Functioning subscale were used to collect data. Generalized Estimating Equations were applied for data analysis. RESULTS: Approximately 59.6%-77.6% of primary family caregivers presented unhealthy family functioning during the 6-month post-discharge period. Significant reductions in family functioning of primary family caregivers were noted in the group with unhealthy family functioning; however, family functioning of primary family caregivers remained unchanged in the group with healthy family functioning over 6 months. Affiliate stigma and family empowerment significantly accounted for the changes in family functioning of primary family caregivers in the groups with unhealthy and healthy family functioning, respectively. CONCLUSION: This study highlights affiliate stigma and family empowerment as long-term predictors of changes in family functioning for primary family caregivers and as pivotal targets of mental health care. CLINICAL RELEVANCE: Family-centered interventions with a focus on ameliorating affiliate stigma and enhancing family empowerment are recommended to improve family functioning for primary family caregivers of patients with schizophrenia at different periods after hospital discharge.

Visfatin Polymorphisms, Lifestyle Risk Factors and Risk of Oral Squamous Cell Carcinoma in a Cohort of Taiwanese Males.

Oral cancer is the eighth greatest generally diagnosed cancer amongst males worldwide and the fourth most generally malignancy amongst Taiwanese males. The pro-inflammatory adipocytokine visfatin promotes tumor growth. Elevated plasma visfatin levels have been identified in patients with oral squamous cell carcinoma (OSCC), although the biological mechanisms underlying the involvement of visfatin in the pathogenesis of OSCC are not well understood. Moreover, no information is available regarding associations between visfatin polymorphisms and carcinogenic lifestyle factors with OSCC. This study, therefore, investigated the effects of four visfatin gene polymorphisms (rs11977021, rs61330082, rs2110385, and rs4730153) and carcinogenic lifestyle factors (betel nut chewing, alcohol consumption and cigarette smoking) on the risk of developing OSCC in 1,275 Taiwanese males with OSCC, and 1,195 healthy males (controls). We also examined the associations between these visfatin genotypes and OSCC histopathological prognostic factors (pathological stage, tumor status, lymph node status, and metastasis). We found that compared with subjects with the CC genotype of SNP rs11977021, those with the CT+TT genotype were less likely to progress OSCC. In addition, an association was found between the rs4730153 variant and lymph node metastasis in the OSCC cohort.

Effectiveness of a brief family strengths-oriented therapeutic conversation intervention for patients with schizophrenia and their caregivers.

PURPOSE: To examine the effects of a brief family strengths-oriented therapeutic conversation (FAM-SOTC) intervention on symptom severity of patients with schizophrenia and family coping and caregiver burden for family caregivers. DESIGN: A quasi-experimental research design with repeated measures. METHODS: A convenience sample of 72 dyads of patient-family caregivers was recruited from randomized inpatient psychiatric rehabilitation units in a psychiatric hospital in Taiwan. Sixty-one patient-family caregiver dyads that comprised the intervention group (n = 29) and control group (n = 32) completed questionnaires at four time points (baseline, immediate, one- and three-months post-intervention). Demographic questionnaires and clinical information, Brief Psychiatric Rating Scale, Family Crisis-Orientation Personal Evaluation Scales, and Zarit Burden Interview were used to collect data. Generalized estimating equations were used to assess the differences in symptom severity, family coping, and caregiver burden between the two groups. FINDINGS: As compared to the control group, the intervention group showed statistically significant improvements over three months in symptom severity as well as family coping, especially acquiring social support, reframing, and mobilizing social support for family caregivers. Caregiver burden in the intervention group was ameliorated immediately and one month after the intervention rather than a three-month post-intervention. CONCLUSIONS: A brief FAM-SOTC intervention proved to be favorable for alleviating psychiatric symptoms of patients coupled with an improvement in family coping and burden in family caregivers encountering schizophrenia. CLINICAL RELEVANCE: Integration of a brief family therapeutic conversation intervention into the routine psychiatric rehabilitation services delivery is recommended to help patients and their family caregivers effectively manage schizophrenia.

The impact of Aurora kinase A genetic polymorphisms on cervical cancer progression and clinicopathologic characteristics.

The aims of this study were to explore the involvement of Aurora kinase A (AURKA) gene single nucleotide polymorphisms (SNPs) in uterine cervical cancer that has not yet been investigated. One hundred and six patients with cervical invasive cancer and 94 patients with precancerous lesions, and 302 Taiwanese female individuals were included. AURKA SNPs rs2273535, rs6024836, rs2064863 and rs1047972 were analyzed for genotypic distributions using real-time polymerase chain reaction. There were no statistically significant differences in the genetic frequencies of AURKA SNPs among patients with invasive cancer and those with precancerous lesions of uterine cervix and control women. There were no associations among AURKA SNPs and clinicopathologcal variables and recurrence and survival events. However, in a multivariate analysis, cervical cancer patients with adenocarcinoma (HR: 3.18, 95% CI: 1.23-8.23; p=0.017) and larger tumor (HR: 5.61, 95% CI: 2.10-14.95; p=0.001) had poorer recurrence-free survival. In conclusion, tumor size and pelvic lymph node status rather than AURKA SNPs were the most obvious independent parameter that could significantly predict 5 years survival rate in Taiwanese women with cervical cancer.

Investigation of time-dependent risk of mental disorders after infertility diagnosis, through survival analysis and data mining: a nationwide cohort study.

OBJECTIVES: Infertile patients are vulnerable to mental disorders. However, a time-dependent model predicting the onset of mental disorders specific to infertile patients is lacking. This study examined the risk factors for the development of mental disorders in infertile patients and measured the duration until the occurrence of mental disorders after a diagnosis of infertility. METHODS: A total of 13,317 infertile patients in the 2002-2013 Taiwan National Health Insurance Research Database were observed. The 11 independent variables included in the hypothesised model, together with the dates of infertility and mental disorder diagnoses, were analysed using Cox proportional hazards. Data-mining methods using C5.0 and Apriori supplemented the statistical analyses. RESULTS: The total prevalence rate of mental disorders among infertile patients in Taiwan was 12.41%, including anxiety (4.66%), depression (1.81%) and other mental disorders (5.94%). The average time interval for onset of mental illness identified using survival analysis was 1.67 years. Income, occupation, treatment method, co-morbidity, region and hospital level and ownership were significant predictors of development of mental illness (all p < .05). CONCLUSIONS: The four categories of factors associated with time-dependent onset were demographics, health, health care provider and geographical characteristics. Certain patient characteristics may predict a higher likelihood of onset of a specific mental disorder. Clinical practitioners may use the findings to identify high-risk patients and make timely health interventions.

A Cross Cultural Comparison of Attitude of Mental Healthcare Professionals Towards Involuntary Treatment Orders.

The purpose of this study was to investigate East-West cultural attitudes of mental healthcare professionals (MHPs) towards Involuntary Treatment Orders (ITOs) among Taiwan, England, Wales, and New Zealand. Data on Taiwanese MHPs' views of ITO regime were collected from the National Psychiatric Disease Mandatory Assessment and Community Care Review Committee (N = 176). A national survey instrument was designed to assess the level of support for ITOs among senior clinicians and to determine their views on the importance of various factors in decision-making, the mechanisms through which coercion may work, impediments to its use, and its perceived impact on patients and therapeutic relationships. A descriptive analysis was carried out with data presented as appropriate for the distribution and a t-test was used to detect any differences by respondents. Risk reduction was ranked the most important factor in use of ITOs and reasons for discharging an order. Female respondents had higher approval ratings, with 85 % of agreeing that ITOs were of benefit to the therapeutic relationship, assured long-term stability, and increased medication compliance. The results suggest that clinicians decide the use of ITOs largely based on the risk management, both in terms of starting and ending an order. However, the use of ITOs vary which reflected in the practice. Given this variation in the use of enabling legislation, multidisciplinary input in decision-making is an essential safety mechanism.

[Protecting Safety During Dust Fires and Dust Explosions - The Example of the Formosa Fun Coast Water Park Accident].

This paper will explore the fire and explosion characteristics of cornstarch powder as well as strategies for protecting the safety of people who are involved a dust fire or dust explosion. We discuss the 5 elements of dust explosions and conduct tests to analyze the fire and explosion characteristics of differently colored powders (yellow, golden yellow, pink, purple, orange and green). The results show that, while all of the tested powders were difficult to ignite, low moisture content was associated with significantly greater risks of ignition and flame spread. We found the auto-ignition temperature (AIT) of air-borne cornstarch powder to be between 385°C and 405°C, with yellow-colored cornstarch powder showing the highest AIT and pink-colored cornstarch powder showing the lowest AIT. The volume resistivity of all powder samples was approximately 108 Ω.m, indicating that they were nonconductive. Lighters and cigarettes are effective ignition sources, as their lit temperatures are higher than the AIT of cornstarch powder. In order to better protect the safety of individuals at venues where cornstarch powder is released, explosion control measures such as explosion containment facilities, vents, and explosion suppression and isolation devices should be installed. Furthermore, employees that work at these venues should be better trained in explosion prevention and control measures. We hope this article is a reminder to the public to recognize the fire and explosion characteristics of flammable powders as well as the preventive and control measures for dust explosions.

Impact of tissue inhibitor of metalloproteinases-3 genetic variants on clinicopathological characteristics of urothelial cell carcinoma.

To investigate the distribution of single nucleotide polymorphism (SNP) of tissue inhibitor of metalloproteinases-3 (TIMP-3) in patients with/without urothelial cell carcinoma (UCC), three loci of TIMP-3 SNPs (rs9862 C/T, rs9619311 T/C, rs11547635 C/T) were genotyped via TaqMan allelic discrimination for 424 UCC patients and 848 non-UCC participants. Furthermore, the TIMP-3 mRNA expression and its correlation with clinical characters of urothelial bladder carcinoma was analyzed using The Cancer Genome Atlas database (TCGA). The distribution of all 3 studied SNPs of TIMP-3 was insignificantly different between the UCC and non-UCC groups. However, significantly lower tumor T status was found in TIMP-3 SNP rs9862 CT + TT variant than the wild type (OR: 0.515, 95% CI: 0.289-0.917, P = 0.023). Moreover, the muscle invasive tumor type was significantly correlated to the TIMP-3 SNP rs9619311 TC + CC variant in the non-smoker subgroup (OR: 2.149, 95% CI: 1.143-4.039, P = 0.016). With the TIMP-3 expression data provided in TCGA, significantly higher TIMP-3 mRNA expression was observed in UCC with high tumor stage (P < 0.0001), high tumor T status (P < 0.0001) and high lymph node status (P = 0.0005). In conclusions, TIMP-3 SNP rs9862 variant is associated with lower tumor T status of UCC while TIMP-3 SNP rs9619311 variant is correlated to muscle invasive UCC development in non-smoker.

Behavioral and IL-2 responses to diosgenin in ovariectomized rats.

Neuroimmune system is involved in communication between the endocrine and nervous systems, which may take part in the effects of dioscorea, reversing changes of anxiety-like behavior and interleukin (IL)-2 levels in the brains of ovariectomized (OVX) rats. This study was aimed at evaluating administration of diosgenin, an ingredient of dioscorea, on neuroimmune and behavioral functions in OVX animals. One month after ovariectomy, female Wistar rats were fed daily with diosgenin (0, 10, 50 or 100 mg/kg/day) and the elevated plus-maze and learned helplessness tests were used to measure anxiety-like and depressive behaviors after 23 and 24 days of diosgenin treatment, respectively. In the learned helplessness test, the rats needed to cross from one compartment of the shuttle box to the opposite compartment to avoid or escape the shock. If the rat failed to escape the shock in 10 sec, a "failure" was recorded. Two days after the behavioral tests, the brain was removed to measure levels of IL-2 which was used as an indicator of neuroimmune function. Anxiety-like behavior in the OVX rats was not affected by diosgenin treatment. However, avoidance behavior in the learned helplessness test in the OVX rats with high anxiety (HA) levels was improved by treatment with diosgenin at the dosage of 10mg/kg/day. Interestingly, the number of failures in the same test was increased when the dosage of diosgenin was increased to 50 mg/kg/day, and this was accompanied by an increase in IL-2 levels in the pituitary gland. In addition, treatment with 100 mg/kg/day of diosgenin resulted in decreased IL-2 levels in the amygdala and prefrontal cortex of the OVX rats with low anxiety levels, and in increased IL-2 levels in the amygdala of OVX HA rats. These results show that chronic diosgenin treatment influences IL-2 levels in the brain of OVX rats and affects depressive behavior in OVX HA rats, but not OVX low anxiety rats.

Quality of life of individuals with schizophrenia living in the community: relationship to socio-demographic, clinical and psychosocial characteristics.

AIMS AND OBJECTIVES: To examine the level of quality of life in individuals with schizophrenia and to test its association with socio-demographic, clinical and psychosocial characteristics. BACKGROUND: Quality of life has been a focus of concern in mental health care, yet the level of quality of life and its determinants for individuals with schizophrenia are not well known. DESIGN: Cross-sectional, descriptive design. METHODS: A total of 148 individuals with schizophrenia participated in the study. A demographic information sheet, the 18-item Brief Psychiatric Rating Scale, the Chinese Health Questionnaires, the Mutuality Scale and the World Health Organization Quality of Life Scale, brief version, were used to collect data. Data were analysed with descriptive statistics, Pearson product-moment correlation and stepwise multiple linear regression. RESULTS: Most of participants were single, unemployed, had a low education level and were supported financially by family. Quality of life was positively correlated with age of mental illness onset, mutuality, employment status and monthly household income, whereas it was negatively associated with the length of mental illness, symptom severity and health status. Health status, mutuality, symptom severity, monthly household income and employment status were found to be key significant predictors with mutuality having the greatest effect on quality of life. CONCLUSIONS: The findings increase our understanding of socio-demographic, clinical and psychosocial characteristics influencing the degree of quality of life in individuals with schizophrenia. Incorporation of families and communities into the treatment programmes would enhance patients' capabilities of social integration and satisfaction with their lives. RELEVANCE TO CLINICAL PRACTICE: Health care providers should make use of community-oriented intervention programmes that aim to strengthen psychosocial functioning. Particularly, programmes that enhance health status and mutuality should be identified and developed for both individuals with schizophrenia and their families.

Spousal Concordance and Cross-Disorder Concordance of Mental Disorders: A Nationwide Cohort Study.

OBJECTIVE: Although both partners of a married couple can have mental disorders, the concordant and cross-concordant categories of disorders in couples remain unclear. Using national psychiatric population-based data only from patients with mental disorders, we examined married couples with mental disorders to examine spousal concordance and cross-disorder concordance across the full spectrum of mental disorders. METHODS: Data from the 1997 to 2012 Taiwan Psychiatric Inpatient Medical Claims data set were used and a total of 662 married couples were obtained. Concordance of mental disorders was determined if both spouses were diagnosed with mental disorder of an identical category in the International Classification of Diseases, Ninth Revision, Clinical Modification; otherwise, cross-concordance was reported. RESULTS: According to Cohen's kappa coefficient, the most concordant mental disorder in couples was substance use disorder, followed by bipolar disorder. Depressive and anxiety disorders were the most common cross-concordant mental disorders, followed by bipolar disorder. The prevalence of the spousal concordance of mental disorders differed by monthly income and the couple's age disparity. CONCLUSION: Evidence of spousal concordance and cross-concordance for mental disorders may highlight the necessity of understanding the social context of marriage in the etiology of mental illness. Identifying the risk factors from a common environment attributable to mental disorders may enhance public health strategies to prevent and improve chronic mental illness of married couples.

Association Between MTHFR rs17367504 Polymorphism and Major Depressive Disorder in Taiwan: Evidence for Effect Modification by Exercise Habits.

Background/Aim: Recent studies reported that folate supplementation has beneficial effects on major depression. The Methylenetetrahydrofolate reductase (MTHFR) enzyme is crucial in folate metabolism. This population-based study examined the association between MTHFR rs17367504 polymorphism and major depressive disorder based on exercise habits. Methods: Taiwan Biobank (TWB) provided demographic and genotype data between 2008 and 2015. The biobank participants were Taiwanese aged 30 to 70. Data on major depressive disorder (MDD) were obtained from the National Health Insurance Research Database (NHIRD). Results: A total of 636 individuals were identified with MDD, whereas 17,298 individuals were considered controls. The associations of MTHFR rs17367504 and exercise with MDD risk were estimated using logistic regression models. The distribution of MTHFR rs17367504 genotype frequencies differed significantly between the MDD and control groups. We found that, compared with the AA genotype, the GG genotype was associated with a significantly increased risk of MDD [adjusted odds ratio (aOR), 1.76; 95% confidence interval (CI), 1.05-2.94; p = 0.033]. We found an interaction (p = 0.04) between rs17367504 and exercise, a well-known protective factor for MDD. A substantial increase in the risk of MDD was found among those with GG genotypes who did not exercise (aOR, 2.93; 95% CI, 1.66-5.17; p < 0.001). Conclusions: Our findings indicate that MDD is related to MTHFR rs17367504 and exercise, though the mechanisms remain to be determined.

Impact of LncRNA GAS5 Genetic Variants and the Epidermal Growth Factor Receptor Phenotypes on the Clinicopathological Characteristics of Lung Adenocarcinoma Patients.

The aim of the current study was to evaluate the combined effect of the single nucleotide polymorphism (SNP) in long non-coding RNA growth arrest-specific 5 (GAS5) and the phenotypes of epidermal growth factor receptor (EGFR) on the clinicopathological characteristics of lung adenocarcinoma. The present study examined the relationship between the GAS5 single-nucleotide polymorphisms (SNPs; rs145204276 Ins/Del, rs55829688 T/C) and the clinicopathological factors in 539 lung adenocarcinoma patients with or without EGFR mutations. We found that the genotype distributions of the two GAS5 SNPs between different EGFR genotypes were similar after adjusting for age, gender and smoking history. The GAS5 SNP rs145204276 Ins/Del + Del/Del illustrated a higher distribution with an advanced tumor stage (p = 0.030), larger tumor T status (p = 0.019), positive lymph node status (p = 0.014) and distal metastases (p = 0.011) in the EGFR wild type group. In the subgroup analysis of the EGFR wild type population, the presence of GAS5 SNP rs145204276 Ins/Del + Del/Del was correlated to an advanced tumor stage (p = 0.014) and distal metastases (p = 0.020) in non-smokers. In conclusion, these data indicate that the GAS5 SNP rs145204276 variant may help predict tumor stage, lymph node metastasis and distal metastases in patients with EGFR wild type lung adenocarcinoma.

Multiple Factors Associated With Child Abuse Perpetration: A Nationwide Population-Based Retrospective Study.

Differences in child abuse perpetration between individuals with and without mental disorders remain obscure. This study compared the risk difference and further investigated the association between the category of mental disorders and child abuse perpetration. A total of 681,970 adults from the 2002 to 2013 Taiwan National Health Insurance Research Database were analyzed, including 340,985 patients with psychiatric disorders (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] codes 290.x-319.x) and 340,985 sex- and age-matched individuals without psychiatric disorders. Child abuse perpetration (ICD-9-CM N-codes 995.5x and E-code E967) was the outcome variable. Matched analyses indicated that the risk of child abuse among patients with psychiatric disorders (0.25%) was significantly higher than that among those without psychiatric disorders (0.16%; odds ratio [OR] = 1.464, p < .0001). Among the six categories of mental disorders, the prevalence rates of committing child abuse were significantly higher for personality disorders, substance use, and affective disorders (0.56%, 0.45%, and 0.40%, respectively; p < .0001). Compared with anxiety disorders, substance use disorders were significantly associated with higher odds of child abuse perpetration (OR = 2.032, p < .05), especially physical abuse (OR = 2.018, p < .0001). Psychiatric morbidity was associated with higher odds of child abuse, with substance use determined as the major risk category. Screening high-risk families by using the associated factors is crucial.

Impact of FGFR4 Gene Polymorphism on the Progression of Colorectal Cancer.

Colorectal cancer (CRC) is a multifactorial malignancy, and its high incidence and mortality rate remain a global public health burden. Fibroblast growth factor receptor 4 (FGFR4) is a receptor tyrosine kinase that has been shown to play a key role in cancer development and prognosis via the activation of its downstream oncogenic signaling pathways. The present study aimed to explore the impact of FGFR4 gene polymorphisms on the risk and progression of CRC. Three FGFR4 single-nucleotide polymorphisms (SNPs), including rs1966265, rs351855, and rs7708357, were evaluated in 413 CRC cases and 413 gender- and age-matched cancer-free controls. We did not observe any significant association of three individual SNPs with the risk of CRC between the case and control group. However, while assessing the clinicopathological parameters, patients of rectal cancer possessing at least one minor allele of rs1966265 (AG and GG; AOR, 0.236; p = 0.046) or rs351855 (GA and AA; AOR, 0.191; p = 0.022) were found to develop less metastasis as compared to those who are homozygous for the major allele. Further analyses using the datasets from the Genotype-Tissue Expression (GTEx) Portal and The Cancer Genome Atlas (TCGA) revealed that rs351855 regulated FGFR4 expression in many human tissues, and increased FGFR4 levels were associated with the occurrence, advanced stage, and distal metastasis of colon adenocarcinoma. These data suggest that the amino acid change in combination with altered expression levels of FGFR4 due to genetic polymorphisms may affect CRC progression.

Risk of Mortality and Readmission among Patients with Pelvic Fracture and Urinary Tract Infection: A Population-Based Cohort Study.

Patients with pelvic fractures could encounter various complications during or after treatments. This cohort study investigated the risk of mortality and readmissions in patients with pelvic fractures, with or without urinary tract infections (UTIs), within 30 days following the pelvic fractures. This retrospective cohort study examined claim records from the Longitudinal Health Insurance Database 2000 (LHID2000). We selected patients hospitalized with pelvic fractures between 1997 and 2013 for study. Patients who had index data before 2000 or after 2010 (n = 963), who died before the index date (n = 64), who were aged <18 years (n = 94), or who had a pelvic injury (n = 31) were excluded. In total, the study cohort comprised 1623 adult patients; 115 had UTIs, and 1508 patients without UTIs were used as a comparison cohort. Multivariate analysis with a multiple Cox regression model and Kaplan-Meier survival analysis were performed to analyze the data. Our results showed that the 1-year mortality rate (adjusted hazard ratio [HR]: 2.32; 95% CI: 1.25-4.29) and readmission rate (adjusted HR: 1.72; 95% CI: 1.26-3.34) of the UTI group were significantly higher than those of the non-UTI group. Moreover, the Kaplan-Meier curve for the 1-year follow-up indicated that the UTI group had a higher cumulative risk of both mortality and hospital readmission compared with the non-UTI group. In conclusion, among patients with pelvic fracture, patients with UTI were associated with increased risks of mortality and readmission. Physicians must pay more attention to such patients to prevent UTIs among patients with pelvic fractures during hospitalization and conduct a follow-up after discharge within at least 1 year.

Effect of WW Domain-Containing Oxidoreductase Gene Polymorphism on Clinicopathological Characteristics of Patients with EGFR Mutant Lung Adenocarcinoma in Taiwan.

Lung adenocarcinoma is the most common histological type of non-small cell lung cancer, which accounts for the majority of lung cancers. Previous studies have showed that dysregulation of WW domain-containing oxidoreductase (WWOX) participates in the generation of several cancer types, including lung cancer. However, whether these WWOX polymorphisms are related to the clinical risk of epidermal growth factor receptor (EGFR)-mutated lung adenocarcinoma is worthy of investigation. The present study examined the relationship between the WWOX single-nucleotide polymorphisms (SNPs; rs11545028, rs12918952, rs3764340, rs73569323, and rs383362) and the clinicopathological factors in lung adenocarcinoma patients with or without EGFR mutations. We found that there was no significant difference in the genotype distribution of WWOX polymorphism between EGFR wild-type and EGFR mutant in patients with lung adenocarcinoma. Our results demonstrated that the presence of at least one G genotype (CG and GG) allele on WWOX rs3764340 was associated with a significantly higher risk of nearby lymph node involvement in those patients harboring EGFR mutations (odds ratio (OR) = 3.881, p = 0.010) compared with the CC genotype. Furthermore, in the subgroup of lung adenocarcinoma patients with the EGFR-L858R mutation, both WWOX rs3764340 C/G (OR = 5.209, p = 0.023) and rs73569323 C/T polymorphisms (OR = 3.886, p = 0.039) exhibited significant associations with the size of primary tumors and the invasion of adjacent tissues. In conclusion, these data indicate that WWOX SNPs may help predict tumor growth and invasion in patients with EGFR mutant lung adenocarcinoma, especially those with the EGFR-L858R mutant in Taiwan.

Genetic Variants of lncRNA GAS5 Are Associated with the Clinicopathologic Development of Oral Cancer.

The long noncoding RNA, Growth arrest-specific 5 (GAS5) plays a crucial role in the development of oral cancer. However, potential genetic variants in GAS5 that affect the susceptibility and progression of oral cancer have rarely been explored. In this study, two loci of GAS5 single nucleotide polymorphisms (SNPs) (rs145204276 and rs55829688) were genotyped by using the TaqMan allelic discrimination in 1125 oral cancer patients and 1195 non-oral-cancer individuals. After statistical analyses, the distribution of both the GAS5 SNP rs145204276 and GAS5 SNP rs55829688 frequencies were similar between the study and control groups. However, the patients with GAS5 SNP rs145204276 variants (Ins/Del or Del/Del) showed a higher tendency of moderate to poor cell differentiation of oral cancer (OR: 1.454, 95% CI: 1.041-2.031, p = 0.028). Moreover, the GAS5 SNP rs145204276 variants (Ins/Del or Del/Del) in the non-alcohol-drinking population were associated with significantly advanced tumor stage (OR: 1.500, 95% CI: 1.081-2.081, p = 0.015) and larger tumor size (OR: 1.494, 95% CI: 1.076-2.074, p = 0.016). Furthermore, individuals with the GAS5 SNP rs145204276 variant were associated with a higher expression of GAS5 in the GTEx database (p = 0.002), and the higher GAS5 level was associated with poor cell differentiation, advanced tumor stage and larger tumor size in head and neck squamous cell carcinoma from the TCGA database (all p < 0.05). In conclusion, the GAS5 SNP rs145204276 variant is related to poor-differentiation cell status in oral cancer. Besides, the presence of the GAS5 SNP rs145204276 variant is associated with a worse tumor stage and tumor size in oral cancer patients without alcohol drinking.
