Background: Bisphosphonates are effective in the prevention and treatment of osteoporosis, yet their use is suboptimal.

Objectives: To measure bisphosphonate compliance among first-time users and identify factors associated with compliance.

Methods: We conducted a prospective follow-up of all women aged 45+ in the second largest health management organization in Israel who were prescribed bisphosphonates for the first time. The 4448 women were classified by drug dosage. Persistence and adherence measures of compliance were calculated for each woman over a 1 year period.

Results: Mean bisphosphonate persistence over a year was 216 days, with a mean medication possession ratio of 66%. Women whose medication was changed, whether from weekly to daily or daily to weekly, always had better persistence rates than those who consistently took the original dose. Persistence rates were as follows: 264 days for women who switched back and forth between daily and weekly doses, 229 days for those who switched from daily to weekly, 222 days for those who took the dosage weekly only, 191 days for those who switched to daily dosage, and 167 days for those who took the dosage daily only (P < 0.001). Switchers were also more likely to have adequate adherence rates (MPR[1] ≥ 80%): 81.3%, 76.6%, 67.5%, 61.3% and 52.2% respectively (P < 0.001). More than 20% of women stopped taking their medication within the first month. Women with higher supplemental insurance (offering significant discounts for weekly dose medications) had better persistence rates: 221 vs. 208 days (P = 0.03). Younger women and women on national pension insurance had the lowest persistence rates: 204 and 209 days respectively.

Conclusions: While weekly bisphosphonate takers had better compliance rates, persistence and adherence rates were inadequate for all groups. Changing medication to meet the needs of the patient, discounting weekly medications, and providing follow-up within the first months of prescription may promote compliance. 

Background: Acupuncture and public interest in this modality have increased over recent years in Israel and throughout the western world.

Objectives: To compare the knowledge and attitudes of physicians to medical students with regard to acupuncture.

Methods: An anonymous questionnaire was completed by internists and medical students at the Soroka Medical Center.

Results: There were 122 respondents in all, 57 of them women (46.7%). The study sample included 40 physicians (33%), 39 fifth year medical students (32%) and 43 second year medical students (35%). The majority of participants (93.4%) had never received training in acupuncture and 84.4% had never undergone acupuncture therapy themselves. In these variables there were no significant differences between the physicians and the students. The participants’ level of knowledge of acupuncture was very low, with 40% unable to answer even one question (of eight) correctly. Despite the poor level of knowledge and the lack of personal exposure to acupuncture, 90 participants (74%) believed that acupuncture has more than a placebo effect, and 57 (42%) believed it was important to include acupuncture in medical education. There were no statistically significant differences in the attitudes of physicians and medical students to acupuncture.

Conclusions: The level of knowledge and exposure of physicians and medical students to acupuncture is low. However, both groups have relatively positive attitudes to this modality as an acceptable treatment for health problems and were open to its inclusion in the medical school curriculum.

Background: Carotid artery stenting is used as an alternative to surgical endarterectomy.

Objectives: To determine the outcome of CAS[1] in a retrospective cohort of patients.

Methods: Between July 1999 and March 2003, 56 consecutive patients with carotid artery stenosis who were considered ineligible for surgery were treated (45 male, 11 female, mean age 69). All cases were performed prior to the introduction of distal protective devices in Israel.

Results: Intraprocedural complications included transient neurological findings in 5 patients (8%), cerebrovascular accident in 2 (3%), hemodynamic changes in 11 (18%), and 4 procedural failures. Post-procedural complications included transient ischemic attack in 3 patients and cardiovascular accident in 6 (10%). At 30 days follow-up, three patients (5%) remained with signs of CVA[2]. Two patients (3%) died during the post-procedural period and 16 (28%) during the 5 year follow-up, one due to recurrent CVA and the remainder to non-neurological causes. Five-year carotid Doppler follow-up was performed in 25 patients (45%), which revealed normal stent flow in 21 (84%), 50–60% restenosis in 3 patients (12%) and > 70% restenosis in one patient (4%).

Conclusions: This study confirms that stent procedures are beneficial for symptomatic carotid stenosis in patients not eligible for surgery.

There has been a paradigm shift in the treatment of rheumatoid arthritis in recent years. Early and aggressive treatment with good control of disease activity has improved the prognosis of the disease, however, there is significant variability in the response of patients to different therapeutic agents. Hence it is essential to find the predictors of response to a drug at baseline so that we can avoid the delay in achieving remission and improve the outcome. Here we review the literature on available predictors for treatment response in general and specifically for methotrexate and biological agents. We also look at specific scores or indices that can help predict the response in individual patients.
