Diabetes and further risk of cancer: a nationwide population-based study.

BACKGROUND: Individuals with diabetes have a significantly higher risk of developing various forms of cancer, and the potential biological links between these two diseases are not completely understood. METHODS: This was a longitudinal retrospective nationwide cohort study, a study design that allows us to examine the natural course of cancer development over an extended period of time with a large sample size. Initially, 3,111,975 and 22,208,395 eligible patients aged ≥ 20 years with and without diabetes, respectively, were matched by age, sex, and the Charlson comorbidity index. Ultimately, 1,751,457 patients were selected from each group. Stratified populations for diabetic retinopathy (DR) (n = 380,822) and without DR (n = 380,822) as well as proliferative DR (PDR) (n = 141,150) and non-proliferative DR (NPDR) (n = 141,150) were analyzed in this study. The main outcome measure was the first-time diagnosis of cancer during the follow-up period. RESULTS: We observed a 20% higher risk of total cancer incidence [hazard ratios (HR), 1.20; p < 0.001] in the diabetes cohort compared to the non-diabetes cohort. The highest HR was observed for liver and pancreas cancers. Moderately increased risks were observed for oral, colon, gallbladder, reproductive (female), kidney, and brain cancer. Furthermore, there was a borderline significantly increased risk of stomach, skin, soft tissue, female breast, and urinary tract (except kidney) cancers and lymphatic and hematopoietic malignancies. The stratified analysis revealed that the total cancer incidence was significantly higher in the DR cohort compared to the non-DR cohort (HR, 1.31; p < 0.001), and there was a borderline increased risk in the PDR cohort compared to the NPDR cohort (HR, 1.13; p = 0.001). CONCLUSIONS: This study provides large-scale, nationwide, population-based evidence that diabetes is independently associated with an increased risk of subsequent development of total cancer and cancer at specific sites. Notably, this risk may further increase when DR develops.

Effects of Codeine on Esophageal Peristalsis in Patients With Ineffective Esophageal Motility: Studies Using High-resolution Manometry.

Background/Aims: This study aims to evaluate the effects of acute codeine administration on primary and secondary esophageal peristalsis in patients with ineffective esophageal motility (IEM). Methods: Eighteen IEM patients (8 women; mean age 37.8 years, range 23-64 years) were enrolled in the study. The patients underwent high-resolution manometry exams, consisting of 10 single wet swallows, multiple rapid swallows, and ten 20 mL rapid air injections to trigger secondary peristalsis. All participants completed 2 separate sessions, including acute administration of codeine (60 mg) and placebo, in a randomized order. Results: Codeine significantly increased the distal contractile integral (566 ± 81 mmHg∙s∙cm vs 247 ± 36 mmHg∙s∙cm, P = 0.001) and shortened distal latency (5.7 ± 0.2 seconds vs 6.5 ± 0.1 seconds, P < 0.001) for primary peristalsis compared with these parameters after placebo treatment. The mean total break length decreased significantly after codeine treatment compared with the length after placebo (P = 0.003). Codeine significantly increased esophagogastric junction-contractile integral (P = 0.028) but did not change the 4-second integrated relaxation pressure (P = 0.794). Codeine significantly decreased the frequency of weak (P = 0.039) and failed contractions (P = 0.009), resulting in increased frequency of normal primary peristalsis (P < 0.136). No significant differences in the ratio of impaired multiple rapid swallows inhibition and parameters of secondary peristalsis were detected. Conclusions: In IEM patients, acute administration of codeine increases contraction vigor and reduces distal latency of primary esophageal peristalsis, but has no effect on secondary peristalsis. Future studies are required to further elucidate clinical relevance of these findings, especially in the setting of gastroesophageal reflux disease with IEM.

Treatment Outcomes of Intravesical Botulinum Toxin A Injections on Patients with Interstitial Cystitis/Bladder Pain Syndrome.

Botulinum toxin A (BoNT-A) is effective in reducing bladder hypersensitivity and increasing capacity through the effects of anti-inflammation in the bladder urothelium; however, studies on the treatment outcome of interstitial cystitis/bladder pain syndrome (IC/BPS) are lacking. We investigated the treatment outcome in IC/BPS patients receiving intravesical BoNT-A injections. This retrospective study included IC/BPS patients who had 100U BoNT-A intravesical injections in the past 20 years. The treatment outcomes at 6 months following the BoNT-A treatment were evaluated using the global response assessment (GRA) scale. The treatment outcomes according to the GRA scale include clinical symptoms, urodynamic parameters, cystoscopic characteristics, and urinary biomarkers, and it was these predictive factors for achieving satisfactory outcomes which were investigated. Among the 220 enrolled patients (180 women, 40 men) receiving BoNT-A injections, only 87 (40%) had significantly satisfactory treatment outcomes. The satisfactory group showed significantly larger voided volumes, and lower levels of both the urinary inflammatory protein MCP-1 and the oxidative stress biomarker 8-isoprostane in comparison to the unsatisfactory group. The IC severity and detrusor pressure are predictive factors of BoNT-A treatment outcomes. IC/BPS patients with less bladder inflammation showed satisfactory outcomes with intravesical BoNT-A injections. Patients with severe bladder inflammation might require more intravesical BoNT-A injections to achieve a satisfactory outcome.

Pelvic Floor Myofascial Pain Might Influence Treatment Outcome of Interstitial Cystitis/Bladder Pain Syndrome: A Prospective Study.

BACKGROUND: In patients with interstitial cystitis or bladder pain syndrome (IC/BPS), 85% were found to have pelvic floor myofascial pain (PFMP) and hypertonicity (PFH). However, they physicians are not typically trained to consider or assess PFMP as a contributing factor to patients' IC/BPS symptoms. OBJECTIVE: This study aimed to explore the relationship between PFMP and treatment outcomes in women with IC/BPS. STUDY DESIGN: A prospective study. SETTING: Department of Urology, Medical Center, Hualien, Taiwan. METHODS: Patients with IC/BPS who received any type of treatment were prospectively enrolled. They underwent vaginal digital examination at baseline. PFMP severity was quantified on the visual analog scale (VAS). Subject assessment items included O'Leary-Sant symptom score (OSS), Global Response Assessment (GRA), and Beck's anxiety inventory. Object assessment items included bladder computed tomography (CT), urodynamic parameters, maximum bladder capacity, and grade of glomerulation. RESULTS: A total of 65 women with IC/BPS (mean age, 57.1 ± 11.3 years) were enrolled in the study. Patients with more severe PFMP had significantly higher rate of dyspareunia (P = 0.031); more comorbidities (P = 0.010); higher number of PFMP sites (P < 0.001); and higher OSS (P = 0.012). PFMP severity was not significantly correlated with bladder conditions, whether subjective or objective. Moreover, PFMP severity (VAS) was significantly negatively associated with the GRA score. LIMITATIONS: There was a small sample size and short follow-up duration, the patients in this study are all women, and the applicability to other populations is uncertain. CONCLUSION: PFMP might affect the subjective results of IC/BPS treatment but not the bladder condition. Therefore, in the future treatment of patients with IC/BPS, digital vaginal examinations of pelvic floor muscles should be performed and focused more on the PFM-related conditions, and necessary PFM treatments, such as the vaginal pelvic floor muscle message, should be scheduled.

Transient Hiatal Separation During Straight Leg Raise Can Predict Reflux Burden in Gastroesophageal Reflux Disease Patients With Ineffective Esophageal Motility.

Background/Aims: Straight leg raise (SLR) can be utilized to evaluate the integrity of the esophagogastric junction during high-resolution manometry (HRM). We aim to assess the value of transient hiatal separation during SLR in symptomatic reflux patients. Methods: Consecutive reflux patients undergoing esophageal HRM and pH monitoring were included. Transient hiatal separation was defined by a ≥ 1 cm separation between the lower esophageal sphincter and crural diaphragm during SLR. We compared esophageal motor patterns and reflux monitoring parameters between patients with normal, transiently abnormal and consistently abnormal esophagogastric junction morphology during SLR. Results: Of 85 (56.3% female, mean age: 46.7 ± 12.3 years) completed SLR, esophagogastric junction morphology was normal in 31 (36.5%), transient hiatal separation in 19 (22.3%), and consistently hiatal hernia in 35 (41.2%). The values of total acid exposure time (P = 0.016), longest acid reflux episodes (P = 0.024), and DeMeester scores (P = 0.016) were higher in hiatal hernia compared to patients with non-transient hiatal separation, but there were no differences between those with and without transient hiatal separation. Within ineffective esophageal motility, the presence of transient hiatal separation during SLR significantly associated with a higher total acid exposure time (P = 0.014), higher DeMeester scores (P = 0.019), higher total acid reflux events (P = 0.037), and higher longest acid reflux episodes (P = 0.006). Conclusion: Our work suggests that SLR may have value as a provocative test during HRM, and future outcome studies are warranted to elucidate the clinical relevance of motor abnormalities depicted from SLR.

Menopausal hormone therapy with conjugated equine estrogen is associated with a higher risk of hemorrhagic stroke than therapy with estradiol: a retrospective population-based cohort study.

BACKGROUND: Several studies have shown that menopausal hormone therapy (MHT) reduces the risk of hemorrhagic stroke (HS), but there are no studies comparing the effect of different estrogen types (conjugated equine estrogen [CEE] and estradiol [E2]). METHODS: This retrospective cohort study included menopausal women aged 40-65 years diagnosed between 2000 and 2016 who received MHT with oral CEE or E2 and were registered in Taiwan's National Health Insurance Research Database. The primary outcome was HS. Propensity score matching with menopausal age and comorbidities was performed. Cox proportional hazard regression models were used to calculate the incidence and hazard ratios (HRs) of HS. RESULTS: A total of 14,586 pairs of women were included. The mean menopausal ages of the CEE and E2 groups were 50.45 ± 5.31 and 50.31 ± 4.99 years, respectively. After adjusting for age and comorbidities, the incidence of HS was 1.23-fold higher in women treated with CEE than in those treated with E2 (8.04 vs. 6.49/10,000 person-years), with an adjusted HR of 1.50 (95 % confidence interval [CI] 1.04-2.17). MHT with CEE initiated within 5 years of menopause was associated with a higher risk of HS than MHT with E2 (HR = 1.47, 95 % CI: 1.01-2.14). CONCLUSIONS: In postmenopausal Taiwanese women, MHT with CEE was associated with an increased risk of HS compared to MHT with E2, a risk that women using CEE should discuss with their clinicians. Further large-scale investigations of this population are warranted.

Clinical presentation, videourodynamic characteristics, and treatment outcome in men with interstitial cystitis-like lower urinary tract symptoms.

PURPOSE: In men, lower urinary tract symptoms (LUTS) similar to interstitial cystitis/bladder pain syndrome (IC/BPS) are difficult to diagnose, and treatment outcomes are poor. This study investigated clinical characteristics and videourodynamic study (VUDS) parameters, pathophysiology, and treatment outcomes in men with IC-like LUTS. METHODS: Men with frequency, urgency, dysuria, and bladder pain initially diagnosed as IC/BPS by ESSIC criteria were assessed to rule out other lower urinary tract diseases (LUTD) by voiding diary, digitorectal examination, urinalysis, VUDS, and cystoscopic hydrodistention. Subsequent treatments for LUTD and specific treatment for IC/BPS were based on VUDS and cystoscopic findings. Clinical VUDS characteristics and treatment outcomes were compared with those of women with IC/BPS. RESULTS: Seventy consecutive men (median age 54.5 years) were enrolled. The median maximum bladder capacity under cystoscopic hydrodistention was 650 mL (IQR 495-763) and glomerulation grade was 2 (1.0-2.0). The patients had moderate anxiety and depression severity; 49% had improved treatment outcomes. On VUDS, 42 (60%) patients had variable LUTD, including detrusor overactivity (n = 14), bladder neck dysfunction (n = 15), dysfunctional voiding (n = 3), and poor relaxation of the external sphincter (n = 24); also, 22 (31.4%) had a previous bladder outlet procedure. The self-reported treatment outcome was significantly better for patients with vs. without LUTD (p = 0.014). CONCLUSIONS: Men with IC-like LUTS diagnosed as IC/BPS may have bladder outlet dysfunction as well as bladder dysfunction, causing a hypersensitive and painful bladder. The IC-like symptoms in the patients with LUTD might, in part, originated from bladder outlet dysfunction rather than the bladder alone.

Chinese Herbal Medicines Have Potentially Beneficial Effects on the Perinatal Outcomes of Pregnant Women.

Introduction: Tocolytic treatment is beneficial to pregnant women with a risk of premature labor or miscarriage. However, previous reports have shown that progestogen might not be effective and ritodrine may increase the risk of maternal vascular-related diseases. Chinese herbal products (CHP) are used as alternative therapies for pregnant women. The goal was to evaluate the efficacy of combined tocolytic therapy and CHP therapy in pregnancy outcomes for pregnant women in Taiwan. Materials and Methods: We conducted a retrospective cohort study based on the National Health Insurance Research Database. A total of 47,153 pregnant women treated with tocolytics aged 18-50 years from 2001 to 2015 were selected from two million random samples. According to the medical use of tocolytics and CHP, we divided the users into two groups: western medicine (WM) only (n = 40,961) and WM/CHP (n = 6,192) groups. A propensity score (PS)-matched cohort (6,192 pairs) was established based on baseline confounders. All participants were followed up to perinatal outcomes. Conditional logistic regression analysis was used to examine the effects of CHP use on the odds of miscarriage and preterm birth. Results: The adjusted odds ratio (OR) for premature birth in the WM/CHP group (n = 411, 6.64%) was significantly lower than in the WM group (n = 471, 7,61%) (0,86, 95% confidence interval [CI], 0.74-0.99). Further subgroup analysis based on the usage of formulae that activate blood and remove stasis or purgative formulae, the adjusted OR of preterm birth of those using these formulae was significantly lower in the WM/CHP group (n = 215, 6.32%) than that in the WM group (n = 265, 7.77%) (OR: 0.79, 95% CI: 0.65-0.96). Conclusion: We found that the combination of CHP and tocolytics can be beneficial to pregnant women in the prevention of premature birth. Further research is required to investigate causal relationships.

Utilization of hospice and nonhospice care in patients with end-stage renal disease on dialysis.

Objectives: The prevalence of end-stage renal disease (ESRD) and the number of patients undergoing dialysis in Taiwan are high. Since September 2009, the National Health Insurance has started to provide hospice care to patients with renal failure in Taiwan. Therefore, it is necessary to understand the use of hospice and nonhospice care in patients with ESRD on dialysis. We aim to understand trends in patients with ESRD receiving hospice and nonhospice care as well as medical care efforts during the last month of their lives (2009-2013). Materials and Methods: The cohort study was conducted using 1 million randomly selected samples from the Taiwan Health Insurance Research Database for millions of people in Taiwan in 2009-2013. Descriptive statistics were presented to summarize the characteristics of data. To compare differences between cohorts, Chi-square tests and Student's t-tests were used. Mann-Whitney U-tests were performed for nonnormally distributed data. Mantel-Haenszel test was test for trend. Results: We recruited 770 ESRD patients who underwent hemodialysis; among them, 154 patients received hospice care. Patients who received hospice care had a significantly longer survival time after removal of mechanical ventilator (20 vs. 0 days) and after discontinuation of dialysis (2 vs. 0 days) compared with those who did not receive hospice care. Patients who received hospice care had more pain control (61.04% vs. 17.37%, P < 0.0001) and other symptomatic control (55.84% vs. 43.18% with diuretics, P < 0.05; 64.29% and 48.21% with laxatives, P = 0.0004) medications than those who did not. Nevertheless, the overall medical cost in the hospice group was significantly lower (90 USD and 280 USD, P < 0.0001). Conclusion: Our results suggest that the addition of hospice care may permit patients a longer life-support-free survival time. In addition, despite a more frequent symptomatic controlling agent use, hospice care significantly reduced the overall medical expenditure.

Acute surgical site infection after total knee arthroplasty in patients with rheumatoid arthritis versus osteoarthritis.

Osteoarthritis is the main cause for total knee arthroplasty (TKA), followed by rheumatoid arthritis. Previous studies have reported conflicting results concerning the risk of surgical site infection after TKA for rheumatoid arthritis and osteoarthritis patients. Thus, this study aimed to examine whether rheumatoid arthritis patients had a higher risk of acute surgical site infection after TKA compared to osteoarthritis patients. We conducted a retrospective cohort study using Taiwan's National Health Insurance Research Database of the whole population from 2012 to 2015, and collected the medical records of osteoarthritis patients or rheumatoid arthritis patients who underwent TKA. To evaluate the risk of acute surgical site infection in rheumatoid arthritis patients, propensity score matching was implemented for osteoarthritis patients. Acute surgical site infection was observed in 2.58% of TKA cases in rheumatoid arthritis patients and 2.66% of TKA cases in osteoarthritis patients. Rheumatoid arthritis and osteoarthritis patients had comparable risk for 90-day (odds ratio = 0.81, 95% confidence interval: 0.371-1.768) and 1-year (odds ratio = 0.463, 95% confidence interval: 0.121-1.766) surgical site infection. In conclusion, patients with rheumatoid arthritis were not at higher risk of acute surgical site infection after TKA compared to osteoarthritis patients. The current treatment strategy for patients with RA is safe and appropriate if they require TKA.

Conjugated equine estrogen used in postmenopausal women associated with a higher risk of stroke than estradiol.

This study aimed to evaluate the risk of ischemic stroke (IS) in hormone therapy (HT) with oral conjugated equine estrogen (CEE) and estradiol (E2) in postmenopausal women in Taiwan. A retrospective cohort study was conducted using the Taiwan National Health Insurance Research Database, a population-based healthcare claims dataset. Eligible women, aged 40-65 years, who received HT with E2 and CEE orally were enrolled. The primary outcome was IS. Propensity score matching with menopausal age and comorbidities was used. Cox proportional hazard regression models were used to calculate the incidence and hazard ratios (HRs) for IS. The mean menopausal ages of the E2 and CEE groups were 50.31 ± 4.99 and 50.45 ± 5.31 years, respectively. After adjusting for age and comorbidities, the incidence of IS was 1.17-fold higher in the women treated with CEE than in those treated with E2 (4.24 vs. 3.61/1000 person-years), with an adjusted HR (aHR) of 1.23 (95% confidence interval [CI] 1.05-1.44). Moreover, HT with CEE initiated within 5 years of menopause had a higher HR than E2 (aHR = 1.20; 95% CI 1.02-1.42). In conclusion, HT with oral CEE might be associated with a higher risk of IS than E2 in postmenopausal Taiwanese women. The use of HT with CEE should be cautioned with the risk of IS.

Voiding dysfunctions in patients with non-Hunner's ulcer interstitial cystitis/bladder pain syndrome do not affect long-term treatment outcome.

PURPOSE: The role of urodynamic study in the diagnosis and prognostication of interstitial cystitis/bladder pain syndrome (IC/BPS) is still controversial. This study evaluated the correlation of the baseline voiding dysfunctions and long-term treatment outcome in patients with non-Hunner's ulcer IC (NHIC). MATERIALS AND METHODS: A total of 211 NHIC patients were enrolled. All patients underwent videourodynamic (VUDS) examination at baseline to identify their voiding conditions and received subsequent treatments. The primary endpoint was Global Response Assessment (GRA) at the interview. Secondary endpoints included O'Leary-Sant symptom score (OSS), Visual Analogue Scale (VAS) for pain and the rate of IC symptom flare-up. RESULTS: The mean age was 56.8 ± 12.8 years, and mean duration of IC was 16.0 ± 9.9 years. At baseline, 83 (39.3%) patients had a voiding dysfunction and 132 (62.7%) had 1 to 3 co-morbidities. The duration, co-morbidities, treatments, changes in OSS and VAS, maximum bladder capacity (MBC), glomerulations, GRA and flare-up rate showed no significant difference among different subgroups. When we divided patients by their storage and voiding conditions, patients with non-hypersensitivity bladder (HSB) (n = 32) had significantly greater MBC (P = .002) whereas those with HSB with (n = 76) or without (n = 103) voiding dysfunction had higher glomerulation (P = .021). When we analysed voiding dysfunction subgroups by GRA, patients with a GRA of ≥2 had a significantly shorter duration of disease (13.9 ± 8.6 years, P = .021). There were also significant associations between GRA and the changes of OSS (P < .001) and VAS (P < .001). CONCLUSIONS: VUDS can disclose voiding dysfunction in 39.3% of NHIC patients. With adequate therapy, the voiding dysfunctions in NHIC patients do not affect long-term treatment outcome.

Application of a novel straight leg raise test during high-resolution manometry can predict esophageal contractile reserve in patients with gastroesophageal reflux disease.

BACKGROUND/AIM: Increased intra-abdominal pressure from abdominal compression augments esophageal peristalsis during high-resolution manometry (HRM), and straight leg raise (SLR) while supine increases intra-abdominal pressure. We determined if water swallows performed during SLR can mimic contraction reserve seen with multiple rapid swallows (MRS). METHODS: Consecutive patients evaluated for GERD symptoms completed validated GERD questionnaires, esophageal HRM, and upper endoscopy. Distal contractile integral (DCI) was analyzed during single water swallows (10 × 5 mL), MRS (5 × 2 mL), and during SLR (5x5 mL). Peristaltic breaks were measured using software tools with a 20 mm Hg isobaric contour. Univariate correlational analyses were performed to compare esophageal motor patterns and DCI values during single water swallows, MRS, and SLR. RESULTS: Of 103 study patients (mean age: 46.7 ± 12.3 years, 56.3% female), 50 (48.5%) had ineffective esophageal motility (IEM). Contraction reserve was observed on MRS in 62% with IEM, and 35.8% with normal motility (p = 0.008). DCI was significantly higher during SLR compared to mean single swallow DCI in both IEM and normal motility patients (p < 0.001 for each comparison). In IEM patients, SLR significantly reduced swallows with peristaltic breaks (6.1 ± 3.7 vs 3.6 ± 3.6; p < 0.001) and shortened the length of the largest break (4.8 ± 3.4 vs 3.0 ± 3.0 cm; p < 0.001). DCI response following MRS correlated with DCI with swallows during SLR, with a correlational coefficient (Pearson's r) of 0.70 (p < 0.001). CONCLUSIONS: Swallowing against the resistance of increased intra-abdominal pressure from SLR improves esophageal body peristaltic performance and predicts esophageal body contraction reserve.

Prescription patterns and factors influencing the use of Chinese herbal medicine among pregnant women in Taiwan: a population-based retrospective study.

BACKGROUND: The use of Chinese herbal medicine (CHM) has been widely promoted as a natural and safe way to treat illness during pregnancy. However, prescription patterns and factors influencing its use are largely unknown. Therefore, we conducted a population-based study to address these questions. METHODS: Pregnant women aged 18-50 years were selected from Taiwan's National Health Insurance Research Database between 2001 to 2011. CHM prescriptions and diagnostic records were collected. Demographic data and pre-existing diseases were compared between CHM users and non-users. A multivariate logistic regression analysis was performed to identify possible factors influencing the use of CHM during pregnancy. RESULTS: A total of 81,873 eligible prescription records were identified, and 16,553 pregnant women were prescribed CHM during pregnancy, yielding a CHM prescription rate of 20.2%. The three most frequently used herbs were Scutellariae Radix (Huang Qin) (4.4%), Eucommiae cortex (Du Zhong) (2.5%), and Atractylodes Rhizome (Bai Zhu) (2.4%). The most frequently used herbal formulae were Dang-Guei-Shao-Yao-San (4.1%), Jia-Wei-Xiao-Yao-San (3.5%), and Xiang-Sha-Liu-Jun-Zi-Tang (2.6%). Multivariate logistic regression revealed that subjects with an older age, a university education, a pre-pregnancy history of CHM use, asthma, chronic renal disease, and cardiac valvular disease and living in a residential area other than northern Taiwan had an increase in adjusted odds ratio for CHM use during pregnancy. CONCLUSIONS: In this population-based study, we found that demographic factors and pre-existing diseases were associated with the use of CHM among pregnant women. It is worth noting that Leonuri Herba (Yi Mu Cao) and Shao-Fu-Zhu-Yu-Tang should be used with caution in the first trimester. Further research is needed to explore the safety and effectiveness of the use of CHM in pregnant women.

Similarities and differences between IBS-C and FC with regards to symptomatology, sleep quality and psychological attributes.

BACKGROUND: Irritable bowel syndrome (IBS) and functional constipation (FC) are highly prevalent in the general population and have significant symptom overlap, while the clinical associations and psychological links between IBS and FC remains poorly understood. We aimed to compare the clinical, metabolic and psychological factors between patients with FC patients and constipation predominated IBS. METHODS: We consecutively enrolled 360 patients from the outpatient clinics of Hualien Tzu Chi medical center. Constipation-predominant IBS (IBS-C) and FC were diagnosed based on Rome III criteria. All participants completed the Pittsburg Sleep Quality Index (PSQI) score, the State Trait Anxiety Inventory (STAI) score and the Taiwanese Depression Questionnaire (TDQ) score. RESULTS: Fifty-four patients had FC and twenty-three patients had IBS-C. Compared to asymptomatic controls, FC/IBS-C groups had female predominance (p < 0.001), FC as well as more GI discomforts and inferior psychosocial characteristics (p < 0.05). Compared to FC, IBS-C had higher severity scores of abdominal distention (4.52 ± 1.90 vs. 3.07 ± 1.88) and heartburn (2.17 ± 1.50 vs. 1.46 ± 1.14). However, FC was independently associated with poor sleep quality [adjusted OR: 1.19 (1.08-1.31), p < 0.001] and IBS-C with depression [adjusted OR: 1.07 (1.02-1.12), p = 0.005]. CONCLUSION: Patients with FC and IBS-C shared many similar GI complaints and psychosocial characteristics, however IBS-C had more severe bloating, heartburn and depression and FC had worse sleeping quality.

Predicting factors of recurrence in patients with gastroesophageal reflux disease: a prospective follow-up analysis.

BACKGROUND: Recurrence of gastroesophageal reflux disease (GERD) is common among patients who are no longer receiving proton pump inhibitors (PPIs). This study investigated factors associated with GERD recurrence. METHODS: We included 499 consecutive GERD patients who completed validated reflux and psychological questionnaires before undergoing upper endoscopy. All patients were treated with PPIs and followed up. RESULTS: Recurrence was observed in 89 (30.4%) of 293 patients during the 1-year follow up. Patients with recurrence had a higher prevalence of diabetes mellitus (p = 0.037), higher baseline GERD Questionnaire (GERDQ) scores (p = 0.002), and higher Pittsburgh Sleep Quality Index scores (p = 0.045). Log-rank analysis showed that a GERDQ score of ⩾8 was independently associated with an increased recurrence risk (p = 0.002). The scores of all psychological questionnaires and health-related quality of life questionnaire worsened more at the end of follow up in patients with recurrence than in those without recurrence. Multivariate analysis revealed that a higher GERDQ score was the only independent risk factor for GERD recurrence (p = 0.024). GERD patients who have greater initial symptom burden will have a higher recurrence rate after discontinuing PPIs. CONCLUSIONS: GERD patients with greater initial symptom burden are more likely to have recurrence after discontinuing PPIs. This study highlights the importance of developing a new strategy to prevent GERD recurrence in the management of this common disorder.

Holiday Season and Weekend Effects on Stroke Mortality: A Nationwide Cohort Study Controlling for Stroke Severity.

Background The effect of holiday season admission for stroke on mortality has not been investigated. Thus, we aimed to evaluate whether "holiday season" and "weekend" effects exist on mortality risk for stroke admission. Methods and Results A nationwide cohort study was conducted using Taiwan's National Health Insurance Research Database. We identified all patients admitted for stroke between 2011 and 2015 in Taiwan, and categorized them according to the admission date: holiday season (at least 4 days off) (n=3908), weekend (n=13 774), and weekday (n=49 045). We analyzed in-hospital, 7-day, and 30-day mortality using multivariable logistic regression, adjusting for stroke severity and other confounders. Compared with weekday admissions, holiday season admission for stroke was significantly associated with a 20%, 33%, and 21% increase in in-hospital, 7-day, and 30-day mortality, respectively. Compared with weekend admissions, holiday season admissions were associated with a 24%, 30%, and 22% increased risk of in-hospital, 7-day, and 30-day mortality, respectively. However, mortality did not differ significantly between weekend and weekday admissions. Subanalyses after stratification for age, sex, and stroke type also revealed similar trends. Conclusions We report for the first time a "holiday season effect" on stroke mortality. Patients admitted during holiday seasons had higher mortality risks than those admitted on weekends and weekdays. This holiday season effect persisted even after adjusting for stroke severity and other important confounders. These findings highlight the need for healthcare delivery systems with a consistent quality of round-the-clock care for patients admitted for stroke.

Clinical and psychological characteristics in gastroesophageal reflux disease patients overlapping with laryngopharyngeal reflux symptoms.

BACKGROUND AND AIM: Laryngopharyngeal reflux (LPR) defined as reflux of gastric content reaching above the upper esophageal sphincter is frequently found in patients with gastroesophageal reflux disease (GERD). This study aimed to investigate clinical and psychological differences between GERD patients with or without LPR symptoms. METHODS: This study enrolled 303 consecutive patients with proton pump inhibitor treatment-naïve scheduled for upper endoscopy because of troublesome reflux symptoms and recognized as GERD by non-dyspepsia reflux disease questionnaire score. Included GERD patients were further categorized into two study groups: with or without LPR by reflux symptoms index score. All participants were also evaluated with questionnaires for depression, anxiety, and sleep disturbances. RESULTS: There were 132 (43.6%) GERD patients with LPR symptoms and 171 (56.4%) GERD patients without LPR symptoms. GERD patients with LPR symptoms had more depression (P < 0.001), sleep disturbance (P = 0.002), irritable bowel syndrome (P = 0.008), functional dyspepsia (P = 0.005), and reflux symptoms burden (P < 0.001) than those without LPR symptoms. Erosive esophagitis was more in patients without LPR symptoms (P = 0.03). GERD patients with LPR symptoms (28.8%) had more complex psychological distress than those without LPR symptoms (28.8% vs 14%, P < 0.001). Reflux symptoms burden, sleep disturbance, and erosive esophagitis were independently associated with GERD overlapping with LPR symptoms. CONCLUSIONS: Gastroesophageal reflux disease patients with LPR symptoms appear to have more reflux symptoms, psychological distress, and functional gastrointestinal disturbance but less erosive esophagitis. This work suggests that therapeutic strategy with tailored multidimensional approach is promising for GERD patients overlapping with LPR symptoms.

Sleep Disturbance and Its Association with Gastrointestinal Symptoms/Diseases and Psychological Comorbidity.

BACKGROUND/AIMS: We aimed to investigate gastrointestinal symptoms, clinical characteristics, and psychological factors in subjects with and without sleep disturbance (SD) in a health screening cohort. METHODS: We enrolled 2,752 consecutive subjects during their health checkups. All participants underwent an evaluation with questionnaires. Demographic characteristics and biochemical data were recorded. SD was confirmed when Pittsburgh Sleep Quality Index score was greater than 5. RESULTS: Among the study population (n = 2,674), 956 (36%) individuals had SD. SD was associated with female gender, older age, lower level of education, higher systolic blood pressure, higher serum high-density lipoprotein levels and higher prevalence of functional dyspepsia and irritable bowel syndrome (IBS). SD subjects also had more depression, more anxiety, more severe gastrointestinal reflux disease symptoms and higher prevalence of non-erosive reflux disease (NERD; p < 0.001). SD was -independently associated with female gender (OR 1.75, p < 0.001), older age (OR 1.03, p < 0.001), NERD (OR 1.88, p = 0.004), IBS (OR 1.51, p = 0.043), and depression (OR 1.16, p < 0.001) by multivariate analysis. CONCLUSIONS: Future studies will be needed to clarify the interrelationships among SD, psychological stress, and functional gastrointestinal disorders.
