Background: Evidence has shown that pregnancy failure (PF) in women with systemic sclerosis (SSc) consists mainly of preterm delivery (PD) and intrauterine growth restriction (IUGR). Thyroid dysfunction (TD) and Hashimoto's thyroiditis (HT) represent a common feature of SSc. Since TD has been associated with PF, its presence in SSc women may potentially affect pregnancy outcome. 

Objectives: To analyze the interplay between TD and PF in a cohort of SSc women. 

Methods: SSc women (n=77) and age-matched controls from the general obstetric population (n=50) were included. Clinical/biochemical/instrumental data exploring TD and the visceral involvement were collected in the context of a clinical practice setting. Pregnancy outcome was assessed by registering the history of primary infertility, recurrent spontaneous abortion, PD (≤ 37 gestational week), IUGR, and intrauterine fetal death. 

Results: A higher prevalence of PD/IUGR was recorded in the SSc cohort than the controls (P = 0.04). SSc women with PF showed a higher prevalence of diffuse SSc than women without PF (P = 0.03). Scl-70 positive SSc women had a higher prevalence of PF than women with anti-centromere positivity (P = 0.01). A higher prevalence of HT was recorded in SSc women with PF than in patients without (P = 0.04). 

Conclusions: Our findings support the evidence that women with SSc can have successful pregnancies despite a higher prevalence of PD/IUGR. Diffuse SSc and Scl-70 positivity may predispose SSc women to PF. Routine thyroid workup may be included in the multi-specialist monitoring of SSc women for the early detection of thyroid dysfunctions.

 

Background: Non-infectious uveitis (NIU) leads to severe visual impairment, potentially impacting on health-related quality of life (QoL). 

Objectives: To investigate the impact of NIU on QoL.

Methods: Eighty NIU patients and 23 healthy controls completed the 36-item Short-Form Health Survey (SF)-36. The SF-36 values were statistically analyzed to evaluate differences between patients and healthy controls and to identify correlations between SF-36 subscores and clinical/demographic data. 

Results: NIU patients showed a decrease in the physical component summary score (P < 0.0001) compared to healthy controls, while no difference was highlighted in the mental component summary score (P = 0.97). NIU patients showed a decrease in physical functioning (P = 0.008), role-physical (P = 0.003), bodily pain (P = 0.0001), general health (P < 0.0001), and social functioning (P = 0.01). Physical functioning was lower in patients with acute anterior uveitis (AAU) than in those with panuveitis (P = 0.003). No differences were found between patients with bilateral or unilateral NIU, isolated NIU, or NIU associated with systemic diseases and with or without ocular activity. No correlations were identified between best-corrected visual acuity and SF-36 subscores. Physical functioning (P = 0.02), bodily pain (P = 0.004), and social functioning (P = 0.02) were reduced in males versus females. 

Conclusions: QoL is impaired in individuals with NIU, particularly in the physical domains, general health, and social functioning. AAU affects physical functioning more than panuveitis. NIU seems to affect per se QoL disregarding inflammatory activity, visual impairment, and presence of associated systemic diseases.

 

Background: Pulmonary arterial hypertension (PAH) is a significant consequence of congenital heart disease (CHD). Its presence and severity is associated with increased morbidity and mortality. 

Objectives: To evaluate the clinical and demographic characteristics of adults with congenital heart diseases (ADCHD) and PAH at a single center. 

Methods: A prospective registry of all patients with PAH was conducted between 2009 and 2015. 

Results: Thirty-two patients were identified. The mean age at the last visit was 44 years (range 19–77 years). The prevalence of PAH among all ADCHD patients was 6% (95% confidence interval 4.3%–8.4%). A much higher prevalence (53%) was found in patients with Down syndrome. Most patients with PAH had moderate or severe disease. Fifteen patients (47%) were treated with pulmonary vasodilators and 6 (19%) with combination therapy. The average World Health Organization functional class was 2.6. Morbidity included cerebral vascular accident or transient ischemic attack in 22% (mostly in patients with right-to-left shunt) and arrhythmia in 37% of the patients. During a median follow-up of 3.5 years, 5 patients (15.6%) died. Of 13 women with no mental retardation, 11 were or had been married and all had children (between 1 and 13, mean 3.3). 

Conclusions: Patients with congenital heart disease and PAH have significant morbidity and mortality. PAH is more prevalent in patients with Down syndrome. While pulmonary pressure during the reproductive years was not always known, 27% of women with PAH at the time of the study were multiparous.

 

Background: The prevalence of major malformations in the general population is estimated at 5% of all live births. Prenatal diagnosis is an important scientific tool that allows reliable consultation and improves pregnancy outcome. In 2008, congenital malformations were the leading cause of death in Muslim infants and the second cause of death in Jewish infants in Israel. It is known that folic acid consumption prior to pregnancy decreases the rate of several fetal malformations.

Objectives: To assess the folic acid consumption rate and to characterize variables associated with its use among pregnant women attending a rural medical center. 

Methods: A cross-sectional observational study was conducted at our institution. Pregnant women in the second or third trimester of pregnancy or within 3 days postpartum were interviewed. The main variable measured was the use of folic acid. Demographic variables and the rate of prenatal testing were assessed. A secondary analysis of the population that reported no consumption of folic acid was carried out. 

Results: Out of 382 women who participated in the study, 270 (71%) reported consumption of folic acid. Using a multivariate analysis model, we found that maternal education, planning of pregnancy, and low parity were independent predictors of folic acid consumption. Women who were not consuming folic acid tended to perform fewer prenatal tests during pregnancy.

Conclusions: High maternal educational level, planning of pregnancy, and low parity are related to high consumption rates of folic acid. Women who were not taking folic acid performed fewer prenatal tests during pregnancy. 

Biomarkers are important for guiding the clinical and therapeutic management of all phases of rheumatoid arthritis because they can help to predict disease development in subjects at risk, improve diagnosis by closing the serological gap, provide prognostic information that is useful for making therapeutic choices and assessing treatment responses and outcomes, and allow disease activity and progression to be monitored. Various biomarkers can be used to identify subjects susceptible to the disease and those with pre-clinical rheumatoid arthritis before the onset of symptoms such as rheumatoid factor and anti-citrullinated protein antibodies. They can be correlated with a risk of developing rheumatoid arthritis and can predict more bone erosions and severe disease progression. Biomarkers such as the erythrocyte sedimentation rate and C-reactive protein levels provide information about disease activity, while predictive biomarkers allow clinicians to assess the probability of a treatment response before starting a particular therapy particularly in the era of biological drugs. This move from traditional approaches to patient stratification and targeted treatment should greatly improve patient care and reduce medical costs.

Background: Patients with giant cell arteritis (GCA) suffer from inflammatory diseases often treated by large amounts of corticosteroids. Whether this inflammatory burden also carries an increased risk for cardiovascular morbidity, and especially ischemic heart disease, is not clearly established.

Objectives: To clarify the linkage between GCA and ischemic heart disease. 

Methods: In a cross-sectional study, we assessed the association between GCA and ischemic heart disease, adjusting for cardiovascular risk factors, among GCA patients and matched controls using the database of the largest healthcare provider in Israel.

Results: The study group was comprised of 5659 GCA patients and 28,261 age and gender matched controls. The proportion of ischemic heart disease was higher in the GCA group (27.5% vs. 12.5% among controls, odds ratio 2.65). Diabetes mellitus, hypertension, hyperlipidemia and smoking were also found to have higher concurrency in GCA. After stratifying for those cardiovascular co-morbidities using logistic regression, GCA remained independently associated with ischemic heart disease with an odds ratio of 1.247 (1.146–1.357 P < 0.001).

Conclusions: GCA is associated with both cardiovascular risk factors and ischemic heart disease. Healthcare professionals should not overlook this aspect of the disease when managing GCA patients. 

 

Background: Anti-glomerular basement membrane (GBM) antibody disease, or Goodpasture’s disease, is the clinical manifestation of the production of anti-GBM antibodies, which causes rapidly progressive glomerulonephritis with or without pulmonary hemorrhage. Anti-GBM antibody detection is mandatory for the diagnosis of Goodpasture’s disease either from the serum or kidney biopsy. Renal biopsy is necessary for disease confirmation; however, in cases in which renal biopsy is not possible or is delayed, serum detection of anti-GBM antibody is the only way for diagnosis.

Objectives: To assess the predictive value of positive anti-GBM antibodies in a clinical setting. 

Methods: Data from anti-GBM antibody tests performed at one medical center between 2006 and 2016 were systematically and retrospectively retrieved. We recruited 1914 patients for the study. Continuous variables were computed as mean ± standard deviation, while categorical variables were recorded as percentages where appropriate. Sensitivity and specificity of anti-GBM titers were calculated. Kaplan–Meyer analysis was performed, stratifying survival according to the anti-GBM antibody titers.

Results: Of the 1914 anti-GBM test results detected, 42 were positive, 23 were borderline, 142 were excluded, and 1707 results were negative. Male-to-female ratio was 1:1.2. Sensitivity of anti-GBM test was 41.2% while specificity was 85.4%. Concerning the Kaplan–Meyer analysis, overall survival was 1163.36 ± 180.32 days (median 1058 days). 

Conclusions: Our study highlights the lack of sensitivity of serological testing of anti-GBM titers. Comparing survival curves, the survival correlated with anti-GBM titer only in a borderline way. Because highly sensitive bioassays are not routinely used in clinics, renal biopsy is still pivotal for Goodpasture’s disease diagnosis.

 

Fevers recurring at a nearly predictable rate every 3–8 weeks are the signature symptom of periodic fever, aphthous stomatitis, pharyngitis, cervical adenitis (PFAPA) syndrome, an acquired autoinflammatory disorder which recurs in association with at least one sign among aphthous stomatitis, pharyngitis, and/or cervical lymph node enlargement without clinical signs related to upper respiratory airways or other localized infections. The disease usually has a rather benign course, although it might relapse during adulthood after a spontaneous or treatment-induced resolution in childhood. The number of treatment choices currently available for PFAPA syndrome has grown in recent years, but data from clinical trials dedicated to this disorder are limited to small cohorts of patients or single case reports. The response of PFAPA patients to a single dose of corticosteroids is usually striking, while little data exist for treatment with cimetidine and colchicine. Preliminary interesting results have been published with regard to vitamin D supplementation in PFAPA syndrome, while inhibition of interleukin-1 might represent an intriguing treatment for PFAPA patients who have not responded to standard therapies. Tonsillectomy has been proven curative in many studies related to PFAPA syndrome, although the evidence of its efficacy is not widely shared by different specialists, including pediatricians, rheumatologists and otorhynolaryngologists.

Background: Israel is a country with a sunny climate; however, vitamin D deficiency and insufficiency are common findings in certain populations whose exposure to sunlight is limited. Medical residency is known for long indoor working hours, thus theoretically limiting the opportunities for sun exposure.

Objectives: To evaluate whether the vitamin D status among residents in a single medical center in Tel Aviv is below the normal range.

Methods: Forty-six residents (28 females, 18 males, average age 33.9 ± 2.8 years) in three residency programs (internal medicine, general surgery/obstetrics and gynecology, pediatrics) were recruited. Demographic data, personal lifestyle, physical activity details and sun exposure duration were obtained by a questionnaire. Serum levels for 25(OH)D were analyzed by a radioimmunoassay.

Results: The mean serum 25(OH)D concentration was 29.8 ± 5.8 ng/ml. According to Institute of Medicine definitions, none of the residents were vitamin D deficient and only two residents (4%) were vitamin D insufficient (15 ng/ml each). The level of 25(OH)D was similar among the various medical specialties. The 25(OH)D levels correlated with the duration of sun exposure and the number of offspring (regression analysis: R2 = 9.2%, P < 0.04 and R2 = 8.9%, P < 0.04, respectively), but not with nutritional data, blood chemistry, or extent of physical activity. 

Conclusions: Most of the residents maintained normal or near normal 25(OH)D levels, indicating that the residency program itself did not pose a significant risk for vitamin D deficiency. 

 

Background: Trials have shown superiority of primary percutaneous intervention (PPCI) over in-hospital thrombolysis in ST-elevation myocardial infarction (STEMI) patients treated within 6-12 hours from symptom onset. These studies also included high-risk patients not all of whom underwent a therapeutic intervention. 

Objectives: To compare the outcome of early-arriving stable STEMI patients treated by thrombolysis with or without coronary angiography to the outcome of PPCI-treated STEMI patients.

Methods: Based on six biannual Acute Coronary Syndrome Israeli Surveys comprising 5474 STEMI patients, we analyzed the outcome of 1464 hemodynamically stable STEMI patients treated within 3 hours of onset. Of these, 899 patients underwent PPCI, 383 received in-hospital thrombolysis followed by angiography (TFA), and 182 were treated by thrombolysis only.

Results: Median time intervals from symptom onset to admission were similar while door-to-reperfusion intervals were 63, 45 and 52.5 minutes for PPCI, TFA and thrombolysis only, respectively (P < 0.001). The 30-day composite endpoint of death, post-infarction angina and myocardial infarction occurred in 77 patients of the PPCI group (8.6%), 64 patients treated by TFA (16.7%), and 36 patients of the thrombolysis only group (19.8%, P < 0.001), with differences mostly due to post-infarction angina. One-year mortality rate was 27 (3%), 13 (3.4%) and 11 (6.1%) for PPCI, TFA and thrombolysis only, respectively (P = 0.12).

Conclusions: PPCI was superior to thrombolysis in early-arriving stable STEMI patients with regard to 30-day composite endpoint driven by a decreased incidence of post-infarction angina. No 1 year survival benefit for PPCI over thrombolysis was observed in early-arriving stable STEMI patients.

 

Background: Standardization of the dietetic care process allows for early identification of malnutrition and metabolic disorders, interdisciplinary collaboration among the medical team, and improved quality of patient care. Globally, dietitians are adopting a nutrition care model that integrates national regulations with professional scope of practice. Currently, Israel lacks a standardized dietetic care process and documentation terminology.

Objectives: To assess the utilization of a novel sectoral documentation system for nutrition care in Israel.

Methods: Seventy dietitians working in 63 geriatric facilities completed an online training program presenting the proposed patient-sectoral-model. Training was followed by submission of sample case studies from clinical practice or completion of a case simulation. Application of the proposed model was assessed by measuring the frequency participants implemented different sections of the model and responses to an approval questionnaire.

Results: Fifty-four participants (77%) provided completed cases. Over 80% of participants reported each step of the proposed dietary care process with 100% reporting the “nutrition diagnosis”. Fifty-one dietitians (72.8%) completed the approval survey with the section on nutrition diagnosis receiving a highly favorable response (95%), indicating that the new documentation system was beneficial. Over 80% of participants rated the model useful in clinical practice.

Conclusions: A sectoral approach for documenting dietetic care may be the ideal model for dietitians working in specific patient populations with the potential for improving interdisciplinary collaboration in patient care.
