Our study demonstrates that NASD patients are at a higher risk of developing female infertility.
IMPORTANCE Obstructive sleep apnea (OSA) has been proposed as a risk factor in infertility.However, to date, the association between OSA and male infertility has not been examined in a populationbased study.OBJECTIVE To investigate the risk factor of OSA in male infertility and the outcome of OSA treatment for the risk of male infertility.
Objectives To determine the risk of having OSA in a cohort of female subjects who are infertile and the odds of being infertile in women with OSA. Patients and methods A nationwide, case-control study of female patients 20 years or older diagnosed with female infertility living in Taiwan, from January 1, 2000, through December 31, 2013 (N = 4,078). We identified women who were infertile and created a 2:1 matched control group with women who were not infertile. We used multivariable logistic regression analysis to further estimate the effects of OSA on female infertility. Results In this 14- year retrospective study, we included 4,078 patients having an initial diagnosis of female infertility. Of those women with infertility, 1.38% had a history of OSA compared with 0.63% of fertile controls (p = 0.002). The mean ages in the study groups were 32.19 ± 6.20 years, whereas the mean ages in the control groups were 32.24 ± 6.37years. Women with OSA had 2.101- times the risk of female infertility compared to women without OSA (p<0.001). Conclusion Our study showed that OSA is more commonly seen in infertile women and increases the odds that a woman will be infertile. More studies need to be done on the whether or not diagnosing and treating OSA can decrease the rate of infertility.
Obstructive sleep apnea (OSA) has been reported to increase the risk of motor vehicle accidents. However, only few studies have investigated the effects of OSA on overall risk injury. The aim of study is to investigate whether OSA increases the risk of overall injury. The data were collected during 2000–2015 from Taiwan’s National Health Insurance Research Database. A total of 8901 individuals diagnosed with OSA were inpatients, or outpatients at least three times were enrolled. Finally, 6915 participants with OSA were included as the study cohort. We matched the study cohort with a comparison cohort, at a ratio of 1:4. Cox proportional hazards regression was used to analyse the association between OSA and overall injury. Patients with OSA had 83.1% increased risk of overall injury, compared to non-OSA individuals [adjusted hazards ratio (HR) = 1.831, confidence interval (CI) = 1.674–2.020, p < 0.001]. In the stratified age group, patients aged ≧65 years had the highest risk of injury (adjusted HR= 2.014; CI = 1.842–2.222, p < 0.001). Patients with OSA were at a higher risk of falls, traffic injury, poisoning, suffocation, suicide, and abuse or homicide than non-OSA individuals, with falls and traffic injury as the leading causes of injuries. The data demonstrated that patients with OSA have a higher risk of overall injury. The study results can be a reference for developing injury prevention strategies in the future. The general population and clinicians should have more awareness regarding OSA and its negative effects on injury development.
Zhou and colleagues 1 show that China and its provinces have made some efforts in reducing the burden of many diseases. We regret to see that Taiwan and its health-care system are not considered independent from China.Taiwan launched its national healthcare system in 1995. This insurancebased system is administered by its own government and characterised by good accessibility, comprehensive population coverage (99% of the 23•74 million residents in Taiwan 2 ), short waiting times, relatively low costs and a national health insurance databank for planning, monitoring, and providing health-care services. 3 Moreover, it is of high efficiency and was ranked ninth in last year's Bloomberg Health Care Efficiency Index, which included 56 global economies.Although we appreciate that Maigeng Zhou and colleagues 1 engaged in improving health conditions in China and its provinces, we would like to point out that Taiwan's health-care system is independent from China. Furthermore, Taiwan and its health-care practitioners are also making an effort to make the world a better place to live.We declare no competing interests.
Background Pelvic fracture with hypovolemic shock is a known crucial injury in trauma patients. Pelvic fracture with vessel injury often leads to hemodynamic complications; in a trauma scenario, evidence of other systems being affected is often absent. Bleeding cessation and resuscitation are important for these types of trauma patients. For this purpose, pelvic angiographic embolization is frequently used. Multiple studies have reported that angiographic embolization may cause erectile dysfunction (ED) in hemodynamically stable patients with pelvic fracture. However, no study has evaluated a large patient cohort with a long‐term follow‐up. We hypothesized that angiographic embolization to control bleeding may compromise blood supply to the genitourinary organs or cause secondary neurogenic injury that increases the risk of ED. Our goal was to evaluate the risk of ED following pelvic fractures in male patients treated with pelvic angiographic embolization. Methods We used data from the National Health Insurance Research Database (NHIRD) from 1997 to 2010 provided by the Bureau of National Health Insurance of the Department of Health in Taiwan. We collected disease histories from inpatient files. The disease diagnoses were based on the International Classification of Diseases (ICD), Ninth Revision, Clinical Modification. These data were all deidentified, and we did not contact the patients. As such, informed consent was not needed. Results Eighty‐five and 82,802 patients were included in the case and control cohorts, respectively. All patients were aged 15–45, and the proportion of pelvic fracture locations was equal between the groups. After investigating the causes of ED among male patients aged 15–45 with pelvic fractures using logistic regression analysis in a generalized estimating equations model and after adjusting for the influence of confounders, we found that these patients had high risks (odds ratio (OR): 32.637; 95% confidence interval: 14.137–75.346; P < 0.001) of developing ED post‐angiographic embolization. Conclusions Male patients in Taiwan with pelvic fractures who undergo angiographic embolization to control bleeding have a higher risk of ED than those who do not undergo the procedure. Physicians should practice caution and inform patients of this connection before the procedure.
PurposeNon-apnea sleep disorder (NASD) increases the risk of cardiovascular events, such as hypertension and ischemic heart disease (IHD). Patients with heart failure (HF) are at higher risk for sleep disorder; however, there is no documentation on NASD’s association with HF to date. Therefore, our study aimed to determine whether NASD increases the risk of incident HF.Materials and methodsUsing the outpatient and inpatient data from Taiwan’s Longitudinal Health Insurance Database, we conducted a nationwide cohort study of patients with a first-time diagnosis of NASD in the year 2000 and followed up the risk of incident heart failure until December 31, 2013. We calculated risks and incidence ratios of HF for patients with NASD compared with the general population. The cumulative incidence of NASD and the subsequent risk of HF are assessed by the Kaplan-Meier method and Cox regression using a matched comparison cohort of HF patients without NASD.ResultsThe NASD cohort had an adjusted hazard ratio (HR) of incident HF 19.7% higher than that of the cohort without NASD (95% CI = 1.130–1.270; p<0.001). In the NASD population, the mean interval to HF in males and females were 5.00±3.69 years and 5.00±3.66 years, respectively. The Kaplan-Meier analysis indicated that after the seventh year, the incidence of HF was higher in the NASD cohort than in the control cohort till the end of the follow up.ConclusionsOur study demonstrates that NASD patients are associated with a higher risk of incident HF.
Non-apnea sleep disorder (NASD) increases the risk of motor vehicle accidents. However, systemic review of NASD and its risk for all causes of injury is lacking. The aim of the present study was to provide a detailed demographic data on NASD and all causes of injury in a 14-year follow up. Our study utilized outpatient and inpatient data from the Longitudinal Health Insurance Database between 2000 and 2013 in Taiwan. We enrolled 989,753 individuals aged ≥20 years who were diagnosed with NASD as outpatients ≥3 times or inpatients ≥1 time. We matched the study cohort with a comparison cohort by age, index date and comorbidities at a ratio of 1:4. We used Cox proportional hazards regression to analyze the association of NASD and the cause of injury. In this 14-year follow up study, patients with NASD had 12.96% increased risk of injury compared to that of the control cohort. Fall was the first place of the cause of injury with 670.26 per 105 PYs. In the stratified age group, patients aged ≧65 years had the highest risk of injury (adjusted HR= 1.381; P < .001). Kaplan–Meier analysis showed that the incidence of injury between the with- and without-NASD cohorts started from the first year and persisted until the end of the follow-up. Our study demonstrates that NASD patients were associated with higher risk of all causes of injuries, with falling being the most prevalent diagnosis. The general public should be more aware of this neglected issue of NASD.
