1.  Auricular Acupuncture as a Treatment for Pregnant Women Suffering from Low Back and Posterior Pelvic Pain: A Pilot Study 
Objective
The primary aim of this study was to examine whether one week of continuous auricular acupuncture could reduce low back and posterior pelvic pain associated with pregnancy.
Study Design
A randomized controlled trial was conducted on pregnant women suffering from lower back and posterior pelvic pain. These women were randomized into an acupuncture group, a sham acupuncture group, or a waiting list control group. All participants were followed for 2 weeks.
Results
Baseline and Day 7 showed significant group differences in pain [F= 15, P<0.0001] and in the disability rating index score [F=7, p<0.0001]. The participants in the acupuncture group reported a significant reduction of pain and improvement of functional status as compared to those in the sham acupuncture and control groups.
Conclusion
One week of continuous auricular acupuncture decreases the pain and disability experienced by women with pregnancy related low back and posterior pelvic pain.

2.  Is Commercially Available Point Finder Accurate and Reliable in Detecting Active Auricular Acupuncture Points? 
Abstract
Objectives
This study was done to determine the specificity and sensitivity of a commercial Pointer Plus (Point finder) in detecting a region of low skin resistance on the ear.
Design
This was a prospective blinded study.
Setting/location
The study was done at the Yale New Haven Hospital, New Haven, CT.
Subjects
The subjects were men and women who work at Yale New Haven Hospital.
Interventions
There were no interventions.
Outcome measures
Correlations were made between self-reported musculoskeletal pain and the detection of low skin resistance on the ear.
Results
The positive predictive value for Pointer Plus detecting low skin resistance correlating to the neck region of French auricular map is 0.76 (76%). The positive predictive value for Pointer Plus to detect low skin resistance area correlating to the low back region of French auricular map is 0.25. The positive predictive value for Pointer Plus in detecting any low in skin resistance on the external auricles in patients who complained of more than two musculoskeletal pains is 0.29.
Conclusions
The specificity and sensitivity of a commercial Pointer Plus (point finder) in detecting a region of low skin resistance on the ear being unreliable, depending on the correlating area based on a published auricular map. Additional assessments are needed to support the clinical practice.

3.  Association of response to hepatitis B vaccination and survival in dialysis patients 
BMC Nephrology  2012;13:97.
Background
The status of immunocompromised patients is well recognized in end stage renal disease (ESRD). As described recently, this acquired immune dysfunction in the uremic milieu may be one of the main pathogenic factors for mortality in ESRD. The aim of this study was to determine the relationship between the immune response following a hepatitis B vaccination (HBV vaccination) and the survival of maintenance dialysis patients.
Methods
A total of 156 patients (103 on hemodialysis and 53 on continuous ambulatory peritoneal dialysis) were recruited. After receiving a full dose of the HBV vaccination, all patients were followed up for to 5 years to evaluate the association of patient survival, cause of mortality, and immune response.
Results
The response rate to the hepatitis B vaccination was 70.5%. There was no significant association between the immune response and the 5-year survival rate (p =0.600) or between the post-vaccination anti-HBs titers and the 5-year survival rate (p = 0.201). The logistic prediction model with the coefficient as non-response following HBV vaccination, diabetes mellitus, old age, and low albumin level could significantly predict infection-cause mortality (sensitivity = 0.842, specificity = 0.937).
Conclusion
There was no significant association between the immune response to HBV vaccination and the 5-year survival rate. However, non-response following HBV vaccination might be associated with infection-cause mortality in dialysis patients.
