Resistant hypertension is associated with an increased cardiovascular risk compared to patients controlled on a similar multi-drug regimen.

The long-term risk associated with resistant hypertension compared to other phenotypes of hypertension is still unclear. We aimed to assess cardiovascular and renal outcomes over 10 years of follow-up of patients with uncontrolled resistant hypertension (uRH) compared to a similarly treated (≥ 3 medication classes including a diuretic) and adherent group whose blood pressure is under control. This retrospective cohort study utilized the computerized database of Maccabi Healthcare Services, a state-mandated health provider covering 25% of the Israeli population.

Design and implementation of a novel interior permanent magnet bearingless slice motor.

In this paper, we present a bearingless motor with a novel segmented dipole interior permanent magnet (IPM) slice rotor. The segmented dipole IPM rotor contains a unique pattern of interior permanent magnets arranged to generate a dipole air gap flux pattern. The magnets are encapsulated within an electrical steel rotor structure.

Teaching medical informatics skills during a clinical clerkship.

Medical students use many forms of medical electronic resources (MER) during clinical clerkships. Such resources may be inaccurate, irrelevant or inappropriate, yet most medical students do not receive guidance on the use of MER. During the earliest clinical clerkship we gave a series of seminars and assignments on the use of MER.

A new approach to developing cross-cultural communication skills.

The need for cross-cultural training (CCT) increases as physicians encounter more culturally diverse patients. However, most medical schools relegate this topic to non-clinical years, hindering skills development. Some residency programs have successfully addressed this deficit by teaching cross-cultural communication skills in a teaching objective structured clinical examination (tOSCE) context.

Prediction of renal impairment in elderly patients with congestive heart failure treated with captopril.

This study assessed the usefulness of the oral captopril test in the prediction of renal impairment among elderly patients with congestive heart failure (CHF). Forty-seven patients aged > or = 65 years with CHF (EF < 40%) participated in a prospective nonrandomized series. Blood samples for plasma renin activity (PRA) were drawn before and 60 minutes after 50 mg of oral captopril.

Intensive home-care surveillance prevents hospitalization and improves morbidity rates among elderly patients with severe congestive heart failure.

The purpose of this study was to examine the impact of intensive home-care surveillance on morbidity rates of elderly patients with severe congestive heart failure. Forty-two patients aged 78 +/- 8 years who had severe congestive heart failure (New York Heart Association functional classes III through IV, mean ejection fraction 27% +/- 6%), were examined at least once a week at home by internists from the district hospital and by a trained paramedical team. The year before entry to the home-care program was compared to the first year of home surveillance.

Assessment of emergency medicine: a comparison of an experimental objective structured clinical examination with a practical examination.

An emergency medicine and trauma programme was implemented at Ben Gurion University Medical School in Israel. Clinical performance assessment of the first-year course in emergency medicine and trauma was done using a practical examination (PE). In the continuous process of critically reviewing the course objectives and assessment methods the objective structured clinical examination (OSCE) was chosen, for the first time in our medical school, as a tool for course development as well as evaluation of the existing PE.

Indium 111 labeled white blood cell scintigraphy for the diagnosis of upper abdominal abscesses in a child with Wiscott-Aldrich syndrome.

We report on a case of multiple hepatic abscesses in an immunodeficient patient where initial radiologic evaluation by ultrasonography and computed tomography confused early management by failing to demonstrate the abscesses and by suggesting other diagnoses. Indium 111 (In-111) white blood cell (WBC) scanning with Tc-99 liver-spleen scan subtraction accurately demonstrated subcapsular hepatic abscesses in four out of four sequential studies, and later confirmed resolution of the abscesses. We suggest that In-111 WBC scanning may be used as a highly specific method of diagnosing suspected upper abdominal abscesses in children.

The ability to sensitize host cells for destruction by autologous complement is a general property of lipoteichoic acid.

Previous studies have demonstrated that lipoteichoic acid (LTA) from Streptococcus pneumoniae binds to erythrocytes and renders them susceptible to lysis by autologous complement. The present study was performed to determine whether LTA from two other gram-positive bacterial species had the ability to render mammalian cells susceptible to lysis by autologous complement. Human erythrocytes were sensitized with LTA from S.
