PurposeUnderstanding health utilization trends in the elderly population is pivotal for Medicare and policymakers. This study evaluates the association between hearing status and health utilization outcomes in a representative sample of elderly Medicare beneficiaries.Materials and methodsWe employed the 2017 Medicare Current Beneficiary Survey (MCBS), which includes self-reported hearing loss data and weighted health utilization information. Analyses were limited to Medicare beneficiaries aged 65 and older without hearing aids. Multivariable logistic regression was performed to assess association between self-reported hearing loss and health utilization outcomes.ResultsOf 7160 respondents, 55.1%, 39.9% and 4.9% reported no trouble hearing, little trouble hearing, and a lot of trouble hearing, respectively. On multivariable logistic regression, both a little and a lot of trouble hearing were associated with trouble accessing care (little trouble hearing: odds ratio [OR] = 1.79, 95% confidence interval [CI]: 1.33–2.40, p < 0.001; lot of trouble hearing: OR = 2.89, 95% CI: 1.81–4.60, p < 0.001) and emergency room (ER) visits (little trouble hearing: OR = 1.24, 95% CI: 1.08–1.42, p = 0.002; lot of trouble hearing: OR = 1.44, 95% CI: 1.10–1.89, p = 0.01). A lot of trouble hearing was associated with avoiding doctor visits (OR = 1.63 95% CI: 1.21–2.21, p = 0.002). Self-reported hearing status was not associated with inpatient or skilled nursing facility (SNF) admission on adjusted analyses.ConclusionsIncreasing reported hearing loss severity is associated with decreased access to and avoidance of routine medical visits, and increased utilization of ER visits. These findings have important implications for Medicare, clinicians and policymakers. Further studies should evaluate if hearing aids can mitigate these outcomes. 相似文献

Potential impact of the sewer system on the applicability of alcohol and tobacco biomarkers in wastewater‐based epidemiology 下载免费PDF全文
Jochen F. Mueller Guangming Jiang Steve Carter Phong K. Thai 《Drug testing and analysis》2018,10(3):530-538
Understanding the actual consumption of alcohol and tobacco in the population is important for forming public health policy. For this purpose, wastewater‐based epidemiology has been applied as a complementary method to estimate the overall alcohol and tobacco consumption in different communities. However, the stability of their consumption biomarkers – ethyl sulfate, ethyl glucuronide, cotinine, and trans‐3′‐hydroxycotinine – in the sewer system has not yet been assessed. This study aimed to conduct such assessment using sewer reactors mimicking conditions of rising main, gravity sewer, and wastewater alone, over a 12‐hour period. The results show that cotinine and trans‐3′‐hydroxycotinine are relatively stable under all sewer conditions while ethyl sulfate was only stable in wastewater alone and gradually degraded in rising main and gravity sewer conditions. Ethyl glucuronide quickly degraded in all reactors. These findings suggest that cotinine and trans‐3′‐hydroxycotinine are good biomarkers to estimate tobacco consumption; ethyl sulfate may be used as a biomarker to estimate alcohol consumption, but its in‐sewer loss should be accounted for in the calculation of consumption estimates. Ethyl glucuronide, and probably most of glucuronide compounds, are not suitable biomarkers to be used in wastewater‐based epidemiology due to their in‐sewer instability. 相似文献

In Cambodia, nearly half of pregnant women attend antenatal care (ANC), which is an entry point of services for prevention
of mother-to-child transmission of HIV (PMTCT). However, most of ANC services are provided in health centres or fields, where
laboratory services by technicians are not available. In this study, those voluntary confidential counselling and testing
(VCCT) counsellors involved in PMTCT were trained by experienced laboratory technicians in our centre on HIV testing using
Determine (Abbot Laboratories) HIV1/2 test kits through a half-day training course, which consisted of use of a pipette, how
to process whole blood samples, and how to read test result. The trained counsellors were midwives working for ANC and delivery
ward in our centre without any experience on laboratory works. The objective of this study was to assess the feasibility of
the training by evaluating the proficiency of the trained non-laboratory staffs. The trained counsellors withdrew blood sample
after pre-test counselling following ANC, and performed the rapid test. Laboratory technicians routinely did the same test
and returned reports of the test results to counsellors. Reports by the counsellors and the laboratory technicians were compared,
and discordant reports in two groups were re-tested with the same rapid test kit using the same blood sample. Cause of discordance
was detected in discussion with both groups. Of 563 blood samples tested by six trained VCCT counsellors and three laboratory
technicians, 11 samples (2.0%) were reported positive in each group, however four discordant reports (0.7%) between the groups
were observed, in which two positive reports and two negative reports by the counsellors were negative and positive by the
laboratory technicians, respectively. Further investigation confirmed that all the reports by the counsellors were correct,
and that human error in writing reports in the laboratory was a cause of these discordant reports. These findings lead us
the conclusion that the half-day training using the rapid and simple test was feasible for non-laboratory staffs to attain
enough proficiency to implement VCCT services for PMTCT in resource-limited settings, and that human error was more likely
to occur in laboratory before giving reports to counsellors. 相似文献

Control of severe hemorrhage using C-clamp and arterial embolization in hemodynamically unstable patients with pelvic ring disruption 总被引:1,自引:0,他引:1

Introduction
Hemorrhage is the leading cause of death in patients with a pelvic fracture. The majority of blood loss derives from injured retroperitoneal veins and broad cancellous bone surfaces. The emergency management of multiply injured patients with pelvic ring disruption and severe hemorrhage remains controversial. Although it is well accepted that the displaced pelvic ring injury must be rapidly reduced and stabilized, the methods by which control of hemorrhagic shock is achieved remain under discussion. It has been proposed to exclusively use external pelvic ring stabilization for control of hemorrhage by producing a ‘tamponade effect’ of the pelvis. However, the frequency of clinically important arterial bleeding after external fixation of the pelvic ring remains unclear. We therefore undertook this retrospective review to attempt to answer this one important question: How frequently is arterial embolization necessary to control hemorrhage and restore hemodynamic stability after external pelvic ring fixation?Materials and methods
We performed a retrospective review of 55 consecutive patients who presented with unstable types B and C pelvic ring fractures. Those patients designated as being in hemorrhagic shock (defined as a systolic blood pressure less than 90 mmHg after receiving 2 L of intravenous crystalloid) were treated by application of the pelvic C-clamp. Patients who remained in hemorrhagic shock, or were determined to be in severe shock (defined as mandatory catecholamines or more than 12 blood transfusions over 2 h), underwent therapeutic angiography within 24 h in order to control bleeding.Results
Fourteen patients were identified as being hemodynamically unstable (ISS 30.1±11.3 points) and were treated with a C-clamp. In those patients with persistent hemodynamic instability, arterial embolization was performed. After C-clamp application, 5 of 14 patients required therapeutic angiography to control bleeding. Two patients died, one from multiple sources of bleeding and the other from an open pelvic fracture (total mortality 2/14, 14%).Conclusions
Although the C-clamp is effective in controlling hemorrhage, one must be aware of the need for arterial embolization to restore hemodynamic stability in a select subgroup of patients.99.

In the dentate gyrus, the synthesis of the opioid peptide, dynorphin, is modulated by a variety of stimuli. In order to elucidate the cellular and molecular mechanisms regulating the synthesis of dynorphin in the hippocampus, we have established a routine primary cell culture of dentate granule neurons and identified granule-like neurons by a characteristic marker, dynorphin, in these cultures. Cultures were prepared from 7-day-old rat pups and maintained in medium with 2% fetal bovine serum. These cultures contained approximately 20% neurons and survived for over 4 weeks. After 2 weeks in culture, neurons expressing dynorphin-A and its messenger RNA were detected using immunocytochemistry and in situ hybridization, respectively. In dentate cultures, enkephalin-, cholecystokinin-, neuropeptide Y- and substance P-positive cells were observed in addition to dynorphin-positive cells with immunocytochemistry. The results suggest that dentate gyrus cell cultures provide a valid in vitro model for studying molecular mechanisms regulating prodynorphin gene expression. 相似文献
