Hemolytic anemia (HA) renders erythropoietic stress on the bone marrow and has been linked to osteoporosis. In this nationwide retrospective cohort study, we examined this correlation by utilizing the Taiwan National Health Insurance Research Database (NHIRD). We identified two cohorts, matching population with and without HA in a 1:4 ratio. A total of 2242 HA patients and 8968 non-HA patients were enrolled. Patients with HA had a significantly higher cumulative incidence (log-rank test p = 0.0073), higher incidence density (5.11 vs. 3.76 per 1000 persons-years), and a 1.31-fold risk of developing osteoporosis than non-HA patients (aHR = 1.31, 95% C.I. 1.04–1.63, p = 0.01). After adjusting for age, sex, and comorbidities, patients with factors including female (aHR = 2.57, 95% C.I. 2.05–3.22, p < 0.001), age > 65 (aHR = 9.25, 95% C.I. 7.46–11.50, p < 0.001), diagnosis of cholelithiasis (aHR = 1.76, 95% C.I. 1.20–2.58, p = 0.003) and peptic ulcer disease (aHR = 1.87, 95% C.I. 1.52–2.29, p < 0.001) had significantly higher risk of osteoporosis. We propose that this correlation may be related to increased hematopoietic stress, increased consumption of nitric oxide (NO) by hemolysis, and the inhibitory effects of iron supplements on osteogenesis through the receptor activator of nuclear factor κB ligand (RANKL)/Osteoprotegerin pathway and the Runt-related transcription factor 2 (RUNX2) factor. Our findings suggest that patients with hemolytic anemia are at a higher risk of developing osteoporosis, and it would be in the patient’s best interest for physicians to be aware of this potential complication and offer preventative measures.

AbstractThe incidence of herpes zoster in psoriasis patients is higher than in the general population. However, the association between herpes zoster risk and different systemic therapies, especially biologic agents, remains controversial. This study investigated the association between herpes zoster risk and several systemic antipsoriasis therapies. This prospective open cohort study was conducted using retrospectively collected data from the Taiwan National Health Insurance Research Database. We included 92,374 patients with newly diagnosed psoriasis between January 1, 2001, and December 31, 2013. The exposure of interest was the “on-treatment” effect of systemic antipsoriasis therapies documented by each person-quarter. The outcome was the occurrence of newly diagnosed herpes zoster. During a mean follow-up of 6.8 years, 4834 (5.2%) patients were diagnosed with herpes zoster after the index date. Among the systemic antipsoriasis therapies, etanercept (hazard ratio [HR] 4.78, 95% confidence interval [CI] 1.51–15.17), adalimumab (HR 5.52, 95% CI 1.72–17.71), and methotrexate plus azathioprine (HR 4.17, 95% CI 1.78–9.82) were significantly associated with an increased risk of herpes zoster. By contrast, phototherapy (HR 0.76, 95% CI 0.60–0.96) and acitretin (HR 0.39, 95% CI 0.24–0.64) were associated with a reduced risk of herpes zoster. Overall, this study identified an association of both etanercept and adalimumab with an increased risk of herpes zoster among psoriasis patients. Acitretin and phototherapy were associated with a reduced risk.

Studies revealed that there are various determinants of mortality among HIV positives after ART initiation. These determinants are so variable with context and dynamic across time with the advancement of cares and treatments. In this study we tried to identify determinants of mortality among HIV positives after initiating ART. A retrospective cohort study was conducted among 416 ART attendees enrolled between July 2005 to January 2012 in Nekemte Referral Hospital, Western Ethiopia. Actuarial table was used to estimate survival of patients after ART initiation and log rank test was used to compare the survival curves. Cox proportional-hazard regression was applied to determine the independent determinants of time to death. The estimated mortality was 4%, 5%, 6%, 7%, and 7% at 6, 12, 24, 36 and 48 months respectively with mortality incidence density of 1.89 deaths per 100 person years (95% CI 1.74, 3.62). Forty years and above AHR = 3.055 (95% CI 1.292, 7.223), low baseline hemoglobin level (AHR = 0.523 (95% CI .335, 0.816)), and poor ART adherence (AHR 27.848 (95% CI 8.928, 86.8)) were found to be an independent determinants of mortality. These determinants of mortality have to be taken into account to enhance better clinical outcomes of ART attendees.

Study Participants

We investigated the effects of statins on tuberculosis (TB) and pneumonia risks in asthma–chronic pulmonary disease overlap syndrome (ACOS) patients. We extracted data of patients diagnosed as having ACOS during 2000–2010 from the Taiwan National Health Insurance Research Database and divided them into statin users and nonusers. All study participants were followed up from the index date until death, withdrawal from insurance, or TB and pneumonia occurred (31 December 2011). The cumulative TB and pneumonia incidence was analyzed using Cox proportional regression analysis with time-dependent variables. After adjustments for multiple confounding factors including age, sex, comorbidities, and use of medications [statins, inhaled corticosteroids (ICSs), or oral steroids (OSs)], statin use was associated with significantly lower TB [adjusted hazard ratio (aHR) 0.49, 95% confidence interval (CI) 0.34–0.70] and pneumonia (aHR 0.52, 95% CI 0.41–0.65) risks. Moreover, aHRs (95% CIs) for statins combined with ICSs and OSs were respectively 0.60 (0.31–1.16) and 0.58 (0.40–0.85) for TB and 0.61 (0.39–0.95) and 0.57 (0.45–0.74) for pneumonia. Thus, statin users had lower TB and pneumonia risks than did nonusers, regardless of age, sex, comorbidities, and ICS or OS use. Pneumonia risk was lower among users of statins combined with ICSs or Oss and TB risk was lower among the users of statins combined with OSs.

The Impact

Background Cluster headache (CH) is well known to show a seasonal predilection; however, the impact of temperature and other meteorological factors on cluster periods (or bouts) has not been established. Methods This nationwide survey included 758 patients with episodic CH retrieved from the Taiwan National Health Insurance Research Database from 2005 to 2009. Corresponding meteorological recordings were obtained from the Central Weather Bureau. A case-crossover study design was used to investigate the association between cluster periods and meteorological factors. Results A total of 2452 episodes of cluster periods were recorded. The cluster periods were most frequent in the autumn and least frequent in the winter. Seasonal changes from winter to spring and from autumn to winter also increased the frequency of cluster periods. The risk of cluster periods increased when there was a higher mean temperature on event days (odds ratio (OR), 1.014, 95% confidence interval (CI), 1.005–1.023, p = 0.003) or within seven to 56 days. Either an increase or a decrease in temperature (0.05℃/day) following a warm period (mean temperature ≥26℃) was associated with the onset of cluster periods. In contrast, a greater increase in temperature (0.15℃/day) following a cold period (mean temperature < 21℃) was needed to evoke cluster periods. No such associations were found following moderate periods (21℃ ≤mean temperature <26℃). Discussion Our study shows that temperature is associated with precipitating or priming cluster periods. The influence depends on the temperature of the preceding periods.

Background: To investigate the relationship between pleural empyema (PE) and peripheral arterial disease (PAD).Methods: We conducted a retrospective cohort study using data from the National Health Institute Research Database. Univariable and multivariable Cox's proportional hazard regressions were performed to investigate the association between PE and the risk of PAD. Kaplan–Meier method and the differences were assessed using a log-rank test.Results: The overall incidence of PAD was higher in the PE cohort than in the non-PE cohort (2.76 vs. 1.72 per 1,000 person-years) with a crude hazard ratio (HR) of 1.61 [95% confidence interval (CI) = 1.41–1.83]. After adjustment for age, gender, and comorbidities, patients with PE were noted to be associated with an increased risk of PAD compared with those without PE [adjusted HR (aHR) = 1.18, 95% CI = 1.03–1.35]. Regarding the age-specific comparison between the PE and non-PE cohorts, PAD was noted to be significantly high in the ≤ 49 years age group (aHR = 5.34, 95% CI = 2.34–10.1). The incidence of PAD was higher in the first 2 years, with an aHR of 1.35 (95% CI = 1.09–1.68) for patients with PE compared with those without PE.Conclusion: The risk of PAD was higher if patients with PE were younger than 49 years and within the 2-year diagnosis of PE.

Abstract Background: The prohemorrhagic effect of aspirin may cause concern about worse prognoses when treating blunt hepatic or splenic injuries. This study investigated whether preinjury aspirin yields an increasing need for hemostatic interventions.Methods: Admission and outpatient records were extracted from the Taiwan National Health Insurance Research Database (NHIRD) from 2003 to 2015. Patients with splenic or hepatic injuries were identified. Patients with preinjury nonaspirin APAC or with penetrating injuries were excluded. The primary outcome measurement was the necessity of invasive procedures to stop bleeding, including transarterial embolization (TAE) and surgeries. One-to-two propensity score matching (PSM) was used to minimize selection bias. Multilogistic regression (MLR) analysis was used to identify factors associated with hemostatic interventions.Results: 20,470 (60.6%) had blunt hepatic injuries, and 15,235 (45.1%) had blunt splenic injuries, of whom 691 (3.4%) and 667 (4.4%) used preinjury aspirin, respectively. In the blunt hepatic injury cohort, there was no significant difference in the need for hemostatic procedures (TAE (6.1% vs 6.1%, p=1.000), exploratory laparotomy (6.1% vs 6.1%, p=1.000), hepatectomy (3.0% vs 2.7%, p=0.694) or hepatorrhaphy (14.3% vs 15.0%, p=0.681)). MLR analysis showed that preinjury aspirin did not increase the need for hemostatic interventions (OR 0.92, 95% CI 0.73-1.16, p=0.473). Regarding the blunt splenic injury cohort, there was no significant difference in the need for hemostatic procedures (TAE (11.5% vs 10.6%, p=0.547), splenectomy (43.5% vs 41.4%, p=0.407) or splenorrhaphy (3.0% vs 3.3%, p=0.698)). An MLR analysis showed that preinjury aspirin did not increase the need for hemostatic interventions (OR 1.12, 95% CI 0.91-1.38, p=0.290).Conclusions: Preinjury aspirin use is not associated with increased hemostatic procedures in blunt hepatic or splenic injuries.

ObjectivesSpousal clustering of cancer warrants attention. Whether the common environment or high-age vulnerability determines cancer clustering is unclear. The risk of clustering in couples versus non-couples is undetermined. The time to cancer clustering after the first cancer diagnosis is yet to be reported. This study investigated cancer clustering over time among couples by using nationwide data.MethodsA cohort of 5643 married couples in the 2002–2013 Taiwan National Health Insurance Research Database was identified and randomly matched with 5643 non-couple pairs through dual propensity score matching. Factors associated with clustering (both spouses with tumours) were analysed by using the Cox proportional hazard model.ResultsPropensity-matched analysis revealed that the risk of clustering of all tumours among couples (13.70%) was significantly higher than that among non-couples (11.84%) (OR=1.182, 95% CI 1.058 to 1.321, P=0.0031). The median time to clustering of all tumours and of malignant tumours was 2.92 and 2.32 years, respectively. Risk characteristics associated with clustering included high age and comorbidity.ConclusionsShared environmental factors among spouses might be linked to a high incidence of cancer clustering. Cancer incidence in one spouse may signal cancer vulnerability in the other spouse. Promoting family-oriented cancer care in vulnerable families and preventing shared lifestyle risk factors for cancer are suggested.

OBJECTIVETo evaluate the impact of universal contact precautions (UCP) on rates of multidrug-resistant organisms (MDROs) in intensive care units (ICUs) over 9 yearsDESIGNRetrospective, nonrandomized observational studySETTINGAn 800-bed adult academic medical center in New York CityPARTICIPANTSAll patients admitted to 6 ICUs, 3 of which instituted UCP in 2007METHODSUsing a comparative effectiveness approach, we studied the longitudinal impact of UCP on MDRO incidence density rates, including methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, and carbapenem-resistant Klebsiella pneumoniae. Data were extracted from a clinical research database for 2006–2014. Monthly MDRO rates were compared between the baseline period and the UCP period, utilizing time series analyses based on generalized linear models. The same models were also used to compare MDRO rates in the 3 UCP units to 3 ICUs without UCPs.RESULTSOverall, MDRO rates decreased over time, but there was no significant decrease in the trend (slope) during the UCP period compared to the baseline period for any of the 3 intervention units. Furthermore, there was no significant difference between UCP units (6.6% decrease in MDRO rates per year) and non-UCP units (6.0% decrease per year; P=.840).CONCLUSIONThe results of this 9-year study suggest that decreases in MDROs, including multidrug-resistant gram-negative bacilli, were more likely due to hospital-wide improvements in infection prevention during this period and that UCP had no detectable additional impact.Infect Control Hosp Epidemiol 2018;39:534–540

Prevalence Of Dementia

Background. Very few nationwide studies have focused on the variations in the incidence and prevalence of dementia and Alzheimer’s disease (AD) in Asian countries. This study aims to describe the gender and age differences in the incidence and prevalence of dementia and AD in Taiwan. Methods. The data on dementia and AD were acquired from the Taiwan National Health Insurance Research Database from 2004 to 2010. The sex and age-specific rates were standardized, and the differences of gender and age on dementia or AD were assessed using Poisson regression analysis. Results. Over seven years, the prevalence of dementia and AD significantly increased from 4.7 to 7.6 per hundred people (β = 0.0784, p<0.0001) and 2.3 to 3.5 per hundred people (β = 0.0696, p<0.0001), respectively. However, the incidence of both dementia and AD decreased but not significantly from 10.9 to 10.7 and 4.9 to 4.6 per thousand person-years, respectively. Noticeably, both incidence and prevalence increased with age and were higher in women than in men. Conclusions. The standardized incidence rates of dementia and AD are much lower than the data reported in some studies from Europe, the US, and Japan. Further studies are warranted to explore which factors are associated with the differences in the incidence of dementia and AD in Taiwan.
