Purpose: The aim of this study was to assess quality of life (QoL) and obturator functioning in patients having undergone a maxillectomy as a tumor ablative resection and rehabilitation with a prosthetic obturator.Materials and Methods: The University of Washington Quality of Life scale version 4 (UW-QoLv4) and the Obturator Functioning Scale (OFS) were used to evaluate the self-reported QoL and obturator functioning. The effects of demographic and treatment variables on QoL were assessed using age, defect size, postoperative radiotherapy (RT), neck dissection, and dentition.Results: The study included 16 men and 13 women with a mean age of 48.8 years. Of the 29 patients, 16 had a Brown Class 2a or smaller defect and 13 had a Brown Class 2b or larger defect. The mean OFS score (P = .004) and the physical (P = .001) and social-emotional function scores (P = .001) of the patients who received postoperative RT were significantly lower than those who did not receive postoperative RT. The subscales for swallowing (P = .008), saliva (P = .001), pain (P = .001), and shoulder function (P = .002) correlated strongly with postoperative RT on the UW-QoL. The subscales for pronunciation (P = .007) and saliva (P = .002) correlated significantly with RT on the OFS. The mean OFS scores were significantly lower for the patients with a Brown Class 2a or smaller defect than for Brown Class 2b or larger (P = .005).Conclusion: Postoperative RT was the strongest variable affecting QoL in patients with maxillectomy and prosthetic obturator reconstruction. The size of the defect slightly influenced the obturator function; however, it did not influence the overall QoL. [ABSTRACT FROM AUTHOR]

Background: Polycystic kidney disease (PKD) is a common renal disorder affecting approximately 1 in 1000 live births. Tuberculosis (TB) is an infectious disease worldwide. This study investigated the risk of TB infection in patients with PKD.Methods: A nationwide population-based cohort study was performed using Taiwan's National Health Insurance Research Database. We used patients' hospitalization files for the entire analysis during 2000-2012. As per diagnosis, we divided patients into PKD and non-PKD cohorts and the major outcome was TB infection.Results: A total of 13,540 participants with 6770 patients in each cohort were enrolled. The PKD cohort had a higher risk of TB infection than did the non-PKD cohort after adjusting for age, sex, and comorbidities (adjusted hazard ratio (aHR) = 1.91, 95% confidence interval [CI] = 1.51-2.43). When classifying by sites of pulmonary TB (PTB) and extrapulmonary TB (EPTB), the PKD cohort demonstrated a significantly higher risk of EPTB (aHR = 2.44, 95% CI = 1.46-4.08) as well as a risk of PTB (aHR = 1.69, 95% CI = 1.29-2.22). When stratified by the presence or absence of a comorbidity, high TB infection risk was noted in the PKD patients without any comorbidity (HR = 2.69, 95% CI = 1.69-4.30).Conclusions: Taken together, our findings suggest that PKD is associated with a 1.91-fold increased risk of TB infection. Medical professionls should maintain a high index of suspicion in daily practice for patients with PKD, particularly those with EPTB infection. [ABSTRACT FROM AUTHOR]

Objective: To explore whether newly diagnosed iron deficiency anemia (IDA) is associated with subsequent systemic autoimmune disease onset.Methods: The study identified 22,440 patients who received a diagnosis of IDA between 2000 and 2012 from a random sample of 1 million people from Taiwan's National Health Insurance Research Database. The patients with IDA were randomly matched with 89,528 patients with no IDA by age, gender, and index year. We followed the 2 groups until systemic autoimmune disease onset. Cox proportional hazards analysis was used to determine autoimmune disease risk by age, gender, and comorbidities, in terms of hazard ratios (HRs) and 95% confidence intervals (CIs).Results: Adjusted HR (95% CI) of autoimmune disease in the IDA group was 2.37 (1.92-2.92) compared with the non-IDA group. The subgroup analysis indicated that a patient with IDA had a significantly greater risk of autoimmune disease if they were female or had the comorbidities of hypertension, hyperlipidemia, cancer, allergic rhinitis, urticaria, chronic obstructive pulmonary disease, or chronic liver disease. The autoimmune disease was significantly more likely to occur within 2 years after a new diagnosis of IDA.Conclusions: IDA significantly increases autoimmune disease risk, particularly in female patients and patients with certain comorbidities. Clinicians should conduct further clinical evaluations and laboratory tests of autoimmune disease in patients with IDA. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to explore the possible range of change of a single-session music intervention (SMI) on symptom clusters and neurological reactivity for women with breast cancer undergoing chemotherapy.Methods: A parallel and randomized, controlled study with repeated measures design was used. A total of 100 women with breast cancer were randomly assigned to the SMI or a control group. The outcome measurements of symptom cluster were collected using the Multidimensional Fatigue Symptom Inventory, Pittsburgh Sleep Quality Index, the Hospital Anxiety and Depression Scale, and the neurological reactivity with heart rate variability at four time points: before commencement of the intervention (T0), immediately afterward (T1), 1 week later (T2), and 3 weeks after the intervention (T3).Results: Of the 50 women in each group, 46 in the SMI and 48 in the control group completed the post-test at T3. Multivariate analysis of variance indicated that the SMI group had a medium effect in change of symptom clusters compared to the control group at T2. Moreover, after adjusting for baseline between normal and higher levels of sympathetic tone activity, significant differences existed in fatigue and depression at T2 and sleep disturbance at T3.Conclusions: A single-session music intervention can be effectively used to reduce symptom clusters for women with breast cancer. Targeting those who have a higher level of sympathetic tone activity is recommended. [ABSTRACT FROM AUTHOR]

Objectives: To compare estimated prevalence of past-year dental visit (PPYDV) among US adults aged ≥18 years from the Behavioral Risk Factor Surveillance System (BRFSS) to estimates from the Medical Expenditure Panel Survey (MEPS), National Health Interview Survey (NHIS), and National Health and Nutrition Examination Survey (NHANES).Methods: We estimated PPYDV adjusted for covariates (age, race/ethnicity, education level, poverty status, edentulism) using BRFSS, MEPS, and NHIS 1999-2010, and NHANES 1999-2004. We tested trend in overall PPYDV for BRFSS, MEPS, and NHIS from 1999-2010. For 2002 and 2010, we calculated absolute differences (AD) and 95% confidence intervals (CI) in PPYDV between BRFSS and each of the other surveys overall and among subpopulations defined by covariates. We pooled NHANES 1999-2004 data for comparison with BRFSS 2002.Results: From 1999 to 2010, BRFSS (68.5% vs. 67.5%), MEPS (43.5% vs. 39.7%), and NHIS (63.3% vs. 59.7%) showed small but significant decreases in overall PPYDV. In 2002, estimates for overall PPYDV were highest for BRFSS (70.0%) and lowest for MEPS (43.9%) with estimates for NHIS (61.5%) and NHANES (1999-2004: 58.1%) in between; the largest AD (26.2%, 95% CI: 25.0%-27.3%) was between BRFSS and MEPS. ADs were consistent in 2002 and 2010, overall and by covariates, except among edentate persons, where PPYDV estimates from BRFSS and NHIS were similar.Conclusions: Estimates of PPYDV from BRFSS were notably higher than estimates from MEPS, NHIS, or NHANES except among the edentate. Trends in PPYDV over time, however, were consistent across all surveys. [ABSTRACT FROM AUTHOR]

This study was designed to explore Taiwanese school students’ attitudes toward sexual relationships and premarital sex. This was an exploratory descriptive, qualitative study. Focus groups (N = 8) were conducted with 47 adolescents from three high schools in Taiwan. Transcripts were transcribed and thematically analyzed using Atlas V 5.0. Adolescent attitudes toward sexual relationships and premarital sexual behavior comprise the following three dimensions: (1) external incentives, (2) the developmental process, and (3) internal control. External incentives include the normalization of sexual behavior between peers, the desire to feel included in a group, parental influence, and media influence. The developmental process includes imagining the sexual experience and onset of sexual activity. Internal control includes the fear of pregnancy, the fear of parental rejection, and the fear of being judged. These findings can provide a reference for designing future sex education curricula and counseling programs for adolescents. [ABSTRACT FROM PUBLISHER]

Aims and objectives. This study aimed to explore patient perception of the meaning of family involvement in elective surgery decision making in Taiwan. Background. Informed consent is based on respecting patient autonomy. However in cultures where family plays a key role in medical decision making, a patient's perspective of family involvement has not been fully investigated. Design and methods. Based on a phenomenological approach, this study conducted semistructured interviews to elicit the experiences of 10 elective surgery patients in southern Taiwan who had family present during their surgery decision making. An adapted version of Colaizzi's (1978) method was used to analyse narratives. Results. Three themes emerged from the elective surgery patients' perception of the meaning of family involvement in their surgery decision-making process: (1) Primacy of family well-being, (2) family as information broker, and (3) family as patient advocate. Patients articulated reciprocal relationships amongst family members, and they expressed overall family well-being as their ultimate concern when making their treatment decision. The essence of the elective surgery patients' perception of the meaning of family involvement in decision making was 'family as a whole'. Conclusions. Patients' concern for overall family well-being and their perspective that family plays a supportive role in transmitting information and acting as patient advocate during the decision-making process may both enhance and restrict individual patient autonomy. In cultures where family is central in decision making, appropriately involving the family in medical decisions should not be overlooked. Relevance to clinical practice. Understanding and acknowledging the important roles of family in medical decision making from the patients' perspective can enable health professionals to more effectively communicate with patients and their family. Then, health professionals can empower the individual who is making the medical decision based on his or her own needs. [ABSTRACT FROM AUTHOR]

Background/purpose: Despite general recommendation of short-course antibiotic prophylaxis, prolonged antibiotic use is still commonly reported in clinical settings. This study compared the efficacy of 1-day versus 3-day antibiotic prophylaxis in preventing surgical site infection (SSI) in patients undergoing coronary artery bypass graft (CABG).Methods: This prospective, randomized control study was performed in a tertiary-care medical center from June 2002 to April 2004. Patients underwent non-emergency CABG and were randomized into two groups receiving either 1 day or 3 days cefazolin prophylaxis. The SSI rates were compared between the two groups.Results: During the study period, 231 patients were enrolled, 120 in the 1-day group and 111 in the 3-day group. Twenty-two episodes of SSI were observed within 1 month after operation: 13 (10.8%) in the 1-day group and nine (8.1%) in the 3-day group (odds ratio: 1.37; 95% confidence interval: 0.56-3.33; p = 0.48). By logistic regression analysis, 1-day prophylaxis with cefazolin was not associated with higher risk of SSI (adjusted odds ratio: 0.91; 95% confidence interval: 0.32-2.56; p = 0.85).Conclusion: Antibiotic prophylaxis for 1 day in CABG surgery was associated with similar rates of postoperative infection compared with antibiotic prophylaxis of 3 days.

Background/purpose: Betel quid extract (BQE) has been demonstrated to induce matrix metalloproteinase (MMP)-2 expression. This study aimed to establish the possible mechanism involved in this event.Methods: Western blotting, reverse-transcription polymerase chain reaction, and gelatin zymography were used to study the expression level of MMP-2. LY294002, PD98059, U0126, N-acetyl-L-cysteine, SB203580, SP600125, and Bay 11-7082 were used to pretreat OECM-1 cells before BQE treatment and MMP-2 detection.Results: OECM-1 cells were subjected to short-term (10 minutes) or long-term (24 hours) BQE treatment (designated as SBT and LBT, respectively), and we found that both treatments increased MMP-2 protein and extracellular signal-regulated kinase (ERK) phosphorylation levels in a concentration- and time-dependent manner. LBT also increased MMP-2 mRNA level. LBT-induced MMP-2 secretion was not inhibited by PD98059 (up to 50 μM) when ERK was effectively blocked, but was attenuated by LY294002 (0-10 μM) in a concentration-dependent manner. This LBT effect was inhibited strongly by SB203580 (10 μM), SP600125 (10 μM), and Bay 11-7082 (10 μM) and mildly by N-acetyl-L-cysteine (5 mM), but not by U0126 (10 μM).Conclusion: Both SBT and LBT upregulate MMP-2 expression, and LBT-induced MMP-2 expression might be mediated by phosphoinositide 3-kinase, p38 mitogen-activated protein kinase, c-Jun N-terminal kinase, and nuclear factor-κB, and to a lesser extent, by reactive oxygen species, rather than by ERK.

Background: Alternative forms of cigarettes, such as electronic cigarettes (e-cigarettes), are becoming increasingly common among adolescents. Many high schools now provide smoking-prevention education in an attempt to minimize the potential negative health effects and illness burdens e-cigarettes may induce in adolescents. However, it is often difficult to motivate young students to engage with traditional education regarding the harmful effects of tobacco; thus, the development of alternative approaches may be required.Objective: In this study, we aimed to conduct an acceptability evaluation of educational virtual reality games designed to support smoking-prevention measures. We based the acceptability evaluation on the following two experience types: game-playing and content-learning experiences. The paths by which these experience types affect the intention to abstain from smoking were also examined.Methods: We applied a prospective observational study design. We developed educational games based on three-dimensional virtual reality technology, in which participants operated joysticks to complete challenge tasks. To increase the possibility of the games fostering motivation to abstain from smoking, the ARCS motivational model (comprising attention, relevance, confidence, and satisfaction) was used as a framework during the games' design. We measured the participants' game-playing experiences by inquiring about the strength of the ARCS elements; content-learning experiences were measured using overall knowledge improvement and the perceived persuasiveness of the content. A total of 130 students participated in the program. Study hypotheses for this evaluation were derived from a literature review. We used partial least squares structural equation modeling to examine the proposed hypotheses.Results: Based on the responses of the students to questionnaire items concerning attention, relevance, confidence, and satisfaction in the context of the games, most students agreed or strongly agreed that the educational games were motivational, and that their game-playing experiences were positive. Regarding content-learning experiences, there was a significant improvement in knowledge (t129=25.67, P<.001), and most students perceived themselves as being persuaded to abstain from smoking. Attention, relevance, and satisfaction significantly influenced perceived persuasiveness (t=3.19, P<.001; t=4.28, P<.001; and t=3.49, P<.001, respectively); however, confidence did not (t=0.42, P=.67). Perceived persuasiveness, relevance, and satisfaction significantly influenced the intention to abstain from smoking (t=3.57, P<.001). In addition to directly affecting the intention to abstain from smoking, indirect effects were observed from both relevance and satisfaction to intention via perceived persuasiveness (t=2.87, P=.004 and t=2.11, P=.04, respectively). However, intention was not significantly influenced by knowledge improvement.Conclusions: Our findings revealed that the educational games were positively accepted by the participating students. This indicates that the integration of the ARCS framework and persuasive strategies is applicable for smoking-prevention education. We recommend that the games be included as teaching materials for smoking-prevention education. [ABSTRACT FROM AUTHOR]

Abstract: The stability of ketamine hydrochloride injection and dexamethasone sodium phosphate injection, when mixed and stored in polypropylene syringes, was studied. Formulations containing ketamine hydrochloride (50 mg or 600 mg) and dexamethasone sodium phosphate (1 mg) in 0.9% sodium chloride injection (to 14 ml) were prepared and stored at 4°C, 23°C, and 37°C, under normal fluorescent light conditions, for 192 hours. The concentrations of the drugs were determined at 0, 2, 4, 8, 24, 48, 96, and 192 hours using a validated high-pressure liquid chromatography method. The pH, color, and visible particles of each solution were also assessed at each time point. All formulations tested maintained more than 98% of the initial concentrations of both drugs, and no degradation products were detected. The solutions remained clear and colorless and the pH varied within 0.05 units throughout 192 hours. The results indicate that, at the concentrations studied, combinations of ketamine hydrochloride and dexamethasone sodium phosphate in 0.9% sodium chloride injection were physically and chemically stable for at least 192 hours (8 days) when stored in polypropylene syringes.

Objective: To assess the rate of immediate postpartum long-acting reversible contraceptive (LARC) use in a multihospital health care system 2 years before and after the policy was implemented, and to assess factors associated with LARC use and repeat pregnancy rates within 12 months after delivery.Methods: We conducted a retrospective chart review of all patients giving birth at three Cleveland Clinic Ohio hospitals from July 1, 2015, to June 30, 2019. We reviewed the inpatient medication reconciliation to identify the LARC initiation rate. We compared all patients who received inpatient postpartum LARC to a 1:3 matched sample of patients who did not receive LARC, matched by delivery date and location, to identify patient characteristics associated with LARC use. The electronic medical record (Epic) was reviewed to identify new pregnancies occurring within 12 months postdelivery.Results: We identified 17,848 deliveries prepolicy and 18,555 deliveries postpolicy. Immediate postpartum LARC was used by 0.5% (monthly range 0-2.1%) of patients prepolicy and 11.6% (monthly range 8.3-15.4%) of patients postpolicy. Levonorgestrel intrauterine devices (IUDs) were used by 56.5%, implants by 29.1%, and copper IUDs by 14.5% of LARC users. Characteristics associated with LARC use included younger age, public insurance, non-White race, Hispanic or Latina ethnicity, higher body mass index, sexually transmitted infection in pregnancy, and tobacco use. Long-acting reversible contraceptive users had a lower rate of repeat pregnancy at 12 months postpartum compared with the non-LARC group (1.9% vs 3.6%, P<.001).Conclusion: Immediate postpartum LARC use increased after a state policy change mandated universal access and was associated with decreased pregnancy rates in the first year postdelivery.

Background: Our previous trial confirmed that induction chemotherapy (IC) improved long-term survival outcomes in patients with locoregionally advanced nasopharyngeal carcinoma (NPC). In this study, we investigated the impact of IC on long-term quality of life (QoL) in this cohort.Methods: Our trial was a randomised, open-label phase 3 trial comparing IC followed by concurrent chemoradiotherapy (CCRT) versus CCRT alone in patients with stage III-IVB (except T3N0-1) NPC. All participants completed two self-administered questionnaires, the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire C30 (QLQ-C30) and the EORTC QLQ Head and Neck Cancer-Specific Module (H&N35). As per protocol, the questionnaires had to be completed before knowledge of treatment allocation by the patient (baseline). Patients were then approached to enroll at the time of the present study period.Results: Ultimately, QoL data from 228 patients were included in the analysis. Most scales were both statistically and clinically decreased in both groups between baseline and the latest follow-up. The IC followed by CCRT group had significantly better outcome in role functioning, cognitive functioning, social functioning, fatigue, pain, and constipation in QLQ-C30 scales at the last follow-up. Similarly, in H&N35 scales, a significantly better result was observed in pain, sexuality, sticky saliva, pain killers use, nutritional supplements, and weight loss, but a poorer result in senses problems, for those treated by IC followed by CCRT.Conclusion: IC followed by CCRT seemed to have better long-term QoL outcomes compared with CCRT alone in patients with locoregionally advanced NPC.

The excitability of interneurons requires Nav1.1, the α subunit of the voltage-gated sodium channel. Nav1.1 deficiency and mutations reduce interneuron excitability, a major pathological mechanism for epilepsy syndromes. However, the regulatory mechanisms of Nav1.1 expression remain unclear. Here, we provide evidence that neddylation is critical to Nav1.1 stability. Mutant mice lacking Nae1, an obligatory component of the E1 ligase for neddylation, in parvalbumin-positive interneurons (PVINs) exhibited spontaneous epileptic seizures and premature death. Electrophysiological studies indicate that Nae1 deletion reduced PVIN excitability and GABA release and consequently increased the network excitability of pyramidal neurons (PyNs). Further analysis revealed a reduction in sodium-current density, not a change in channel property, in mutant PVINs and decreased Nav1.1 protein levels. These results suggest that insufficient neddylation in PVINs reduces Nav1.1 stability and thus the excitability of PVINs; the ensuing increased PyN activity causes seizures in mice. Consistently, Nav1.1 was found reduced by proteomic analysis that revealed abnormality in synapses and metabolic pathways. Our findings describe a role of neddylation in maintaining Nav1.1 stability for PVIN excitability and reveal what we believe is a new mechanism in the pathogenesis of epilepsy.

Objectives: The invasion into cervical esophagus (ICE) sometimes could be encountered in patients with hypopharyngeal squamous cell carcinoma (HypoSCC). However, the incidence, predictive factors, and prognostic impact of ICE on the patients with HypoSCC remain unclear.Materials and Methods: Patient diagnosis with HypoSCC at the National Taiwan University Hospital between January 2007 and December 2018 were reviewed. All patients were classified into two groups: with and without ICE. The curative treatment included upfront laryngectomy or pharyngo-laryngo-esophagectomy (PLE) with adjuvant chemoradiation, or definite organ-sparing chemoradiation.Results: We analyzed 527 HypoSCC patients, 71 (13.47%) with and 456 (86.53%) without ICE. ICE presented more frequently in females (odds ratio (OR) = 3.01, p = 0.03) and posterior pharyngeal wall (OR = 2.34, p = 0.04). The 5-year disease-free survival of patients with and without ICE were 21.7% and 54.1%, respectively (p < 0.0001) and the 5-year overall survival were 13.1% and 53.8%, respectively (p < 0.0001). Among patients with ICE, the disease-free and overall survival of patients with upfront PLE were worse than the patients without upfront PLE (p = 0.21 and p = 0.27, respectively). After multivariant cox analysis, ICE was an independent risk factor for disease-free survival (p < 0.001) and overall survival (p < 0.001).Conclusion: ICE was occasionally present (13.47%) in HypoSCC patients. Unfortunately, the presence of ICE had a significant impact on disease-free and overall survival. For the HypoSCC patients with ICE, organ-sparing chemoradiation should be considered first as upfront PLE had no additional benefit. [ABSTRACT FROM AUTHOR]
