Background: Heart failure centers with specialized nurse-supervised management programs have been proposed to improve prognosis. The Heart Failure Center in Beit Shemesh, Israel, is located within a large primary care facility. The specialist team supervised the managememt of patients both within the frame of the center and while they were hospitalized.

Objectives: To evaluate the health services utilization by heart failure patients treated at a heart failure center and their clinical outcome.

Methods: In this retrospective study, we compared the clinical outcome of patients treated at a heart failure center to patients who received the standard care in 2013–2014. The clinical outcome included primary care visits, emergency room visits, hospitalizations, and death.

Results: The study comprised 430 heart failure patients; 82 were treated at the heart failure center and 348 under standard care. At baseline, no significant differences were seen in clinical parameters between the groups. Healthcare utilization was higher among the study group. No significant changes in healthcare utilization were found. During follow-up, patients treated in a heart failure center were more likely to get recommended heart failure medications. Mortality was significantly lower in patients treated in the heart failure center compared with those receiving standard care 3.6% vs. 24%, respectively (P = 0.001), hazard ratio 0.19, 95% confidence interval 0.06–0.62, P = 0.005.

Conclusions: Joint management of heart failure by primary clinics and a specialized community heart failure center reduced mortality. There was no decrease in healthcare utilizations among heart failure center patients, despite the reduction in mortality.

Background: Crohn’s disease and ulcerative colitis are the two major classic presentations of inflammatory bowel diseases (IBD). Studies have shown a wide variation in the incidence and prevalence attributed to different geographic and ethnic populations.

Objectives: To assess the clinical characteristics of IBD among Arabs in Israel and to compare them to characteristics of IBD among Ashkenazi Jews.

Methods: This retrospective, comparative study compared the clinical characteristics of IBD among 150 Arabs from the Holy Family Hospital and the Nazareth Hospital EMMS, both located in Nazareth, Israel, to those of 97 age- and sex-matched Ashkenazi Jewish patients from Shaare Zedek Medical Center, Jerusalem, Israel.

Results: The Arab cohort, which included 106 patients (70%) with Crohn's disease and 44 (29%) with ulcerative colitis, was compared to 97 Ashkenazi patients (81% with Crohn's disease and 17% with ulcerative colitis) (P < 0.05). Alcohol consumption was found in both groups, but Arabs smoked more (46% vs. 12%, respectively, P < 0.05). Obstructive phenotype was lower in Arabs (10% vs. 32%, P < 0.05). 5-aminosalicylic acid and anti-tumor necrosis factor alpha were prescribed for the Arab and Ashkenazi groups (89% and 21%, respectively). The need for surgical intervention due to disease severity and/or complications was not significant (22% vs. 24%).

Conclusions: Despite similar reports of NOD2/CARD15 mutations, Crohn's disease is more common than ulcerative colitis within the Arab-Israeli population. Increased smoking rates may explain milder disease severities in Arabs, as reflected by lower obstructive pattern and frequent use of milder therapeutic modalities.

Background: Fibromyalgia is a syndrome of unknown etiology that is characterized by widespread pain, which severely impairs quality of life. Several forms of occupational and alternative therapy have demonstrated beneficial effects in fibromyalgia patients.

Objective: To assess the effects of participation in a floral design course on physical and psychiatric symptoms in a cohort of fibromyalgia patients.

Methods: This study was conducted as an observational study. Women diagnosed with fibromyalgia over the age of 18 were recruited to participate in one of two 12-week flower design (floristry) courses. Demographic details, disease activity indices, and anxiety and depression scores were calculated for all participants at baseline, week 12, and study completion. Physical and mental health of the two groups were compared throughout the study time-points.

Results: The study was completed by 61 female fibromyalgia patients who were included in the final analyses; 31 patients participated in the first floristry course and 30 in the second. Significant improvements in the 36-Item Short Form Survey physical and mental health components, visual analog scale, Fibromyalgia Impact Questionnaire, Hamilton Anxiety Rating Scale, and Hamilton Depression Rating Scale scores for the entire study population and for each group separately could be seen following participation in each floristry course.

Conclusions: Participation in a floristry course may lead to a significant improvement in pain and psychiatric symptoms in fibromyalgia patients. These findings highlight the potential benefit of utilizing occupational therapy programs, such as a floristry course, for improving quality of life in fibromyalgia.

Background: Recently, studies have found that non-alcholic fatty liver disease (NAFLD) is associated with bacterial infections. Attempts to identify risk factors for recurrent urinary tract infections (rUTIs) are still underway.

Objectives: To examine a possible association between NAFLD and rUTIs among premenopausal women.

Methods: In a case-control study, 1009 hospitalized premenopausal women with a UTI during a period of 3 years were retrospectively studied. A total of 186 subjects with rUTIs and 186 controls without a history of rUTIs were included in this study. Each participant had an abdominal ultrasonogram as part of the inclusion criteria. The two groups were compared in terms of risk factors for rUTIs, such as maternal history of rUTIs, use of contraceptives, frequency of sexual intercourse, metabolic syndrome, obesity, use of probiotics, serum levels of vitamin D, and NAFLD. An rUTI was defined as three or more episodes of UTI over a period of 1 year. NAFLD was diagnosed based on abdominal ultrasonography examination.

Results: Mean age of the 372 participants was 39.7 ± 5 years. NAFLD was diagnosed in 81/186 subjects (43.5%) with rUTIs vs. 40/186 controls (21.5%), P = 0.05. Women with rUTIs were more often obese and presented with lower serum levels of vitamin D than controls. Multivariate analysis showed that NAFLD (odds ratio = 1.6, 95% confidence interval 1.3–2.0, P = 0.04) were associated with rUTIs in premenopausal women.

Conclusions: NAFLD was associated with rUTI in premenopausal women, independent of metabolic syndrome. Further studies are needed to confirm this association.

Background: Adverse drug events (ADEs) are a major cause of morbidity and mortality worldwide. Hence, identifying and monitoring ADEs is of utmost importance. The Trigger Tool introduced by the Institute of Healthcare Improvement in the United States has been used in various countries worldwide, but has yet to be validated in Israel.

Objective: To validate the international Trigger Tool in Israel and to compare the results with those generated in various countries.

Methods: A retrospective descriptive correlative analysis surveying four general hospitals in Israel from different geographical regions was conducted. Patient medical charts (n=960) were screened for 17 established triggers and confirmed for the presence of an ADE. Trigger incidence was compared to the actual ADE rate. Further comparison among countries was conducted using published literature describing Trigger Tool validation in various countries.

Results: A total of 421 triggers in 279 hospitalizations were identified, of which 75 ADEs in 72 hospitalizations (7.5%) were confirmed. In addition, two ADEs were identified by chart review only. Mean positive predictive value was 17.81% and overall sensitivity was 97%. We found 1.54 ADEs for every 100 hospitalization days, 7.8 ADEs per 100 admissions, and 1.81 ADEs for every 1000 doses of medication. Of the 77 ADEs identified, 22.7% were defined as preventable.

Conclusions: Our results support the Trigger Tool validity in Israel as a standardized method. Further studies should evaluate between hospital and region differences in ADE rate, in particular for the preventable events.

Background: Inflammatory bowel disease (IBD) prevalence is increasing among Bedouin Arabs in Israel. This population is known to have a high rate of consanguinity. NOD2/CARD15 mutations are well-studied in IBD.

Objectives: To investigate the frequency of NOD2/CARD15 mutations in IBD Bedouin patients and their relevance to disease phenotype.

Methods: The IBD-Arab cohort in southern Israel included 68 patients, of which 25 Crohn's disease (CD) patients and 25 ulcerative colitis (UC) patients consented to participate (72%). Blood samples were obtained from all participants who were genotyped for NOD2/CARD15 variants Arg702Trp, Gly908Arg, and Leu1007fsinsC.

Results: The NOD2/CARD15 mutation frequency was higher in Crohn's disease than in ulcerative colitis patients. Carrier frequency for the Gly908Arg mutation in CD and UC patients was 8/25 (32%) and 3/25 (12%), respectively (P = 0.08). Neither the Arg702Trp nor Leu1007fsinsC mutation was found in our cohort. No homozygous/compound heterozygote mutations were found. Genotype-phenotype analysis revealed that CD patients carrying the Gly908Arg mutation were younger at diagnosis, 22.8 ± 4.5 vs. 28.82 ± 9.1 years (P = 0.04). All carriers were males, compared with 41.2% in non-carriers (P = 0.005). NOD2/CARD15 mutation carriers with UC were older, 67.0 ± 24.5 years compared with 41.2 ± 12.3 years (P = 0.006). No other associations regarding disease localization or other clinical parameter were found.

Conclusions: The frequency of NOD2/CARD15 gene mutations is high in CD and UC among Bedouin Arab IBD patients and is associated with younger age at onset in CD and male gender.

Background: Door-to-balloon time (DTBT) ≤ 90 minutes has become an important quality indicator in the management of ST-elevation myocardial infarction (STEMI). We identified three specific problems in the course from arrival of STEMI patients at our emergency department to initiation of balloon inflation and determined an intervention comprised of specific administrative and professional steps. The focus of the intervention was on triage within the emergency department (ED) and on increasing the efficiency and accuracy of electrocardiography interpretation.

Objectives: To examine whether our intervention reduced the proportion of patients with DTBT > 90 minutes.

Methods: We compared DTBT of patients admitted to the ED with STEMI during the year preceding and the year following implementation of the intervention.

Results: Demographic and clinical characteristics at presentation to the ED were similar for patients admitted to the ED in the year preceding and the year following intervention. The year preceding intervention, DTBT was > 90 minutes for 19/78 patients (24%). The year after intervention, DTBT was > 90 minutes for 17/102 patients (17%). For both years, the median DTBT was 1 hour. Patients with DTBT > 90 minutes tended to be older and more often female. Diagnoses in the ED were similar between those with DTBT ≤ 90 minutes and > 90 minutes. In-hospital mortality was 17% (13/78) and 14% (14/102) for the respective time periods.

Conclusions: An intervention specifically designed to address problems identified at one medical center was shown to decrease the proportion of patients with DTBT > 90 minutes.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as a challenging nosocomial pathogen in the last 50 years.

Objectives: To describe an investigation and containment of an MRSA outbreak in a neonatal intensive care unit (NICU).

Methods: Our NICU is a 25-bed level III unit. Almost 540 neonates are admitted yearly. The index case was an 8 day old term baby. MRSA was isolated from his conjunctiva. Immediate infection control measures were instituted, including separation of MRSA+ carriers, strict isolation, separate nursing teams, and screening of all infants for MRSA. Healthcare workers and parents of positive cases were screened and re-educated in infection control measures. New admissions were accepted to a clean room and visiting was restricted. MRSA isolates were collected for molecular testing.

Results: MRSA was isolated from five infants by nasal and rectal swabs, including the index case. Screening of healthcare workers and families was negative. Two MRSA+ patients already known in the pediatric intensive care unit (PICU) located near the NICU were suspected of being the source. All NICU isolates were identical by pulsed-field gel electrophoresis but were different from the two PICU isolates. The NICU and one of the PICU isolates were defined as ST-5 strain by multilocus sequence typing. One PICU isolate was ST-627. All NICU isolates were Panton–Valentine leukocidin negative and SCCmec type IV. No further cases were detected, and no active infections occurred.

Conclusions: A strict infection control policy and active screening are essential in aborting outbreaks of MRSA in the NICU.

Background: Acute musculoskeletal pain is one of the most commonly reported symptoms among patients visiting the emergency department (ED). Treatment with over-the-counter pain medications, given by nurses, results in improved pain management and reduces the waiting time to drug administration without significant side effects. Opioid analgesics are extensively used for acute pain in the ED. Compared to morphine, oxycodone has a much more specific pharmacological activity, higher analgesic potential, and more tolerable side effects.

Objectives: To assess the degree of pain reduction using different protocols, including dypirone and oxycodone given by nurses, in treating acute musculoskeletal pain in the emergency department (primary outcome) and to evaluate the need for rescue medications (secondary outcome).

Methods: This observational prospective clinical trial compared two groups of 50 patients, each one visiting the ED due to musculoskeletal pain. One group was treated with dipyrone syrup and the other was treated with oxycodone syrup. The primary outcome was pain reduction measured by the Numeric Rating Scale (NRS). The secondary outcome was the difference in need for rescue medications.

Results: The reduction in the NRS was greater in the patients treated with oxycodone. This finding was statistically and clinically significant (P < 0.001). The need for rescue medications was also significantly reduced in this group of patients (P = 0.007).

Conclusions: This study showed that the administration of over-the-counter oxycodone syrup by nurses decreases the post-treatment pain reported by patients, reduces the need for rescue medications, and increases the satisfaction of the medical staff.

Aging has been associated with perceived lowering of health, especially in post-traumatic individuals. The effects may be more complex or even different for Holocaust survivors as they age due to their inherited resilience and life perspective. A cross-sectional study was conducted of Holocaust survivors and a matched comparison group recruited from the general Israeli population. All participants underwent a personal interview and completed the Cumulative Illness Rating Scale and a survey of subjective Likert-scale questions about perceived health. The study comprised 214 older adults: 107 Holocaust survivors and 107 comparison participants; 101 women and 113 men. The mean age for the participants was 80.7 ± 4.7 years (range 68–93). Holocaust survivors did not differ from comparison subjects in general health measures (mean 51.50 ± 3.06 vs. 52.27 ± 3.24, respectively). However, the Holocaust survivors' subjective health was significantly lower, F (2,211) = 4.18, P < 0.05, and associated with decreased quality of life. The present study demonstrates the complex interplay between general and subjective health and suggests that future interventions need to focus on improving the psychological and social well-being of Holocaust survivors to achieve successful aging.

Background: Direct aspiration from suspected pathological tissue and rapid parathyroid hormone analysis may offer a reliable, cost effective alternative to currently used “gold standard” tests.

Objectives: To validate the accuracy of intraoperative measurements of parathyroid hormone levels in parathyroid adenomas.

Methods: A prospective study included 22 patients diagnosed with primary hyperparathyroidism who underwent parathyroidectomy due to an adenoma or hyperplasia. Aspirations of tissues extracted from three adjacent areas (the pathological parathyroid, thyroid, and muscle tissues) were sent for rapid parathyroid hormone analysis. The assay values of these tissue aspirates were compared to the results of the pathology report based on frozen section analysis and the final pathology report.

Results: All assay results were significantly higher for parathyroid tissue 16,800 to 1,097,986 pmol/L (median 26,600), than for either thyroid 1.7 to 415 pmol/L (median 6.5), P < 0.001, or muscle tissue 1.1 to 1230 pmol/L, (median 11.3), P < 0.001. All tissues showing high parathyroid assay values were also verified by pathology examinations: 7 had adenomas and 15 had a differential diagnosis of adenoma or hyperplasia. The frozen section identified all but one (false negative). Rapid intraoperative parathyroid levels > 1500 predicted parathyroid tissue with a 99% level of confidence, while levels between 1000 and 1500 predicted it with 95% confidence. The intraoperative parathyroid hormone assay showed > 70% decrease in 15/21 cases.

Conclusions: Rapid intraoperative parathyroid hormone analysis is a reliable and precise technique, equally accurate for frozen section analysis in predicting with high certainty intraoperative parathyroid tissue.
