Background: Pregestational diabetes mellitus (PGDM) carries a significantly elevated risk of adverse maternal and fetal outcomes. There is evidence that certain interventions reduce the risk for adverse outcomes. Studies have shown that a multi-disciplinary approach improves pregnancy outcomes in women with PGDM.

Objectives: To determine pregnancy outcomes in women with PGDM using a multi-disciplinary approach.

Methods: We retrospectively reviewed consecutive women with pregestational type 1 and type 2 diabetes who were monitored at a high-risk pregnancy clinic at the Sheba Medical Center. Clinical data were obtained from the medical records. All data related to maternal glucose control and insulin pump function were prospectively recorded on Medtronic CareLink® pro software (Medtronic MiniMed, Northridge, CA).

Results: This study comprised 121 neonates from 116 pregnancies of 94 women. In 83% of the pregnancies continuous glucose monitoring (CGM) sensors were applied during a part or all of the pregnancy. Pregnancy outcomes among women who were followed by a multi-disciplinary team before and during pregnancy, and during labor and puerperium resulted in better glucose control (hemoglobin A1c 6.4% vs. 7.8%), lower risk for pregnancy induced hypertension/preeclampsia (7.7% vs. 15.6%), lower birth weight (3212 g vs. 3684 g), and lower rate of large size for gestational age and macrosomia (23.1% vs. 54.2% and 3.3% vs. 28.4%, respectively), compared to data from European cohorts.

Conclusions: The multi-disciplinary approach for treating women with PGDM practiced in the high-risk pregnancy clinic at the Sheba Medical Center resulted in lower rates of macrosomia, LGA, and pregnancy induced hypertension compared to rates reported in the literature.

Background: Admission to an intensive care unit (ICU) is an objective marker of severe maternal morbidity (SMM).

Objectives: To determine the prevalence of obstetric ICU admissions in one medical center in Israel and to characterize this population.

Methods: In this retrospective study the files of women coded for pregnancy, birth, or the perinatal period and admission to the ICU were pulled for data extraction (2005–2013).

Results: During the study period, 111 women were admitted to the ICU among 120,279 women who delivered babies (0.09%). Their average age was 30 ± 6 years, most were multigravida, a few had undergone fertility treatments, and only 27% had complicated previous pregnancies. Most pregnancies (71.2%) were uneventful prior to admission. ICU admissions were divided equally between direct (usually hemorrhage) and indirect (usually cardiac disease) obstetric causes.

Conclusions: The indications for obstetrics ICU admission correlated with the proximate causes of maternal arrest observed worldwide. While obstetric hemorrhage is often unpredictable, deterioration of heart disease is foreseeable. Attention should be directed specifically toward improving the diagnosis and treatment of maternal heart disease during pregnancy in Israel.

Background: Opposition to neonatal Hepatitis B vaccination is a growing trend in Israel.

Objectives: To assess the sociodemographic factors and attitudes associated with non-vaccination of term singleton newborns.

Methods: This prospective, pair-matched, controlled trial was conducted in a tertiary university-affiliated hospital. Data on maternal sociodemographic parameters, delivery, and infant care practices were gathered. Knowledge and references of Hepatitis B virus (HBV) vaccination, vaccination schedule, and health government policies were assessed. A follow-up telephone survey was completed at the age of 7 weeks postpartum regarding vaccine catch-up rate.

Results: Mothers in the study group were mostly Jewish white middle class married multiparous women with some higher education. Hepatitis B serology was not tested in most. Higher rates of rooming-in and exclusive breastfeeding were observed. Knowledge about HBV was stated, multiple sources of information were significantly associated with newborn non-vaccination. Many objected to the timing of the vaccine and its necessity. Multiple medical encounters are viewed as missed opportunities.

Conclusions: Multiple sources of vaccine information are associated with non-vaccination. Medical encounters prior and post-delivery should be used for vaccination education and may improve vaccination coverage.

Background: Guidelines recommend initiation of parenteral biologic or oral target-specific disease-modifying anti-rheumatic drugs (bDMARDs/tsDMARDs) in rheumatoid arthritis (RA) patients who do not adequately respond to conventional DMARDs.

Objectives: To compare the preferred route of administration of bDMARDs or tsDMARDs in RA patients who were previously treated with at least one type.

Methods: A cross-sectional survey was conducted of consecutive RA patients previously prescribed bDMARDs or tsDMARDs. We analyzed the factors associated with patients' preferred route of administration.

Results: The cohort included 95 patients, mostly female (72.6%), seropositive (81.05%), mean age 63.4 ± 11.9 years. The oral route was preferred by 39 patients (41%) and 56 (59%) preferred the parenteral route. Most patients (65.9%) preferred to continue with their current route (P < 0.001). Switching from a current route was less common with patients who were currently using the oral route (13.3% vs. 38.2%, P = 0.04). Many patients (53.8%) who preferred the oral route had never experienced it before, while this was rare (3.6%) regarding the parenteral route (P = 0.0001). Employment status was associated with preference of the subcutaneous route over the intravenous route of bDMARDs (P = 0.01). Of the 21 patients who had previously experienced both parenteral and oral treatment, 16 (76.2%) preferred the oral route.

Conclusions: RA patients preferred to continue treatment with an administration route they have already experienced. However, when choosing an unexperienced route, significantly more patients preferred the oral route. Our results strengthen the understanding of patient preferences, which could improve drug adherence, compliance, and disease outcome.

Background: Male breast cancer (MBC) is a rare disease that is poorly understood. Treatment protocols are widely extrapolated from breast cancer in women.

Objectives: To review the experience with MBC of a single center in Israel over a period of 22 years.

Methods: This single center retrospective study evaluated all patients diagnosed with MBC over a period of 22 years (1993–2015). Data were extracted from patient medical charts and included demographics, clinical, surgical, and oncological outcomes.

Results: The study comprised 49 patients. Mean age at diagnosis was 64.1 ± 13.5 years. The majority were diagnosed at early stages (1A–2A) (54.4%), 30.6% were stage 3B mostly due to direct skin and nipple involvement, and 59.2% of the patients had node negative disease. All of the patients were diagnosed with invasive ductal carcinoma and 30.6% had concomitant ductal carcinoma in situ. Estrogen receptor (ER) status was predominantly positive and luminal B (HER2-) was the most common subtype. Of the patients, 18.4% were BRCA carriers. The majority of patients underwent mastectomy. Radiotherapy was delivered to 46.9% and hormonal therapy to 89.8%. Chemotherapy was administered to 42.9%. Overall survival was 79.6% with a median survival of 60.1 (2–178) months; 5- and 10-year survival was 93.9% and 79.6%, respectively. Progesterone receptor (PR)-negative patients had a significantly improved overall survival.

Conclusions: MBC has increasing incidence. PR-negative status was associated with better overall survival and disease-free interval. Indications to radiotherapy and hormonal therapy need standardization and will benefit from prospective randomized control trials.

Background: The number of investigative esophagogastroduodenoscopies (EGD) in children has increased over several decades, despite their unclear diagnostic yields.

Objectives: To evaluate the indications for performing EGD, their diagnostic yields, and consequences on pediatric patient management.

Methods: A retrospective chart review was performed of consecutive pediatric patients aged 0–18 years, who underwent EGD between January and August 2014.

Results: During the study period, 547 EGD were performed on 478 children. The most frequent indications were suspected celiac disease, chronic non-specific abdominal pain, persistent Helicobacter pylori infection, and gastrointestinal hemorrhage. The yield of the diagnostic EGD was 59.2%, and the most common new diagnoses were celiac disease (28%), Helicobacter pylori-positive gastritis (16.5%), and Crohn’s disease (5.4%). Of the patients with documented follow-up, 74.1% reported improved symptoms. Procedures performed for chronic unexplained abdominal pain had significantly lower yields (26.2%) and only 39.3% improved at follow-up.

Conclusions: Our findings suggest a general high diagnostic yield for EGD in pediatric patients, stemming mainly from patients in whom a specific condition was suspected a priori. However, the role of the procedure in the diagnosis and management of non-specific gastrointestinal complaints was minor suggesting that EGD may be superfluous for some of these patients.

Background: The impact of revascularization of coronary chronic total occlusion (CTO) on survival is unknown. Several studies, which included subjects with varied coronary anatomy, suggested that CTO revascularization improved survival. However, the contribution of CTO revascularization to improved outcome is unclear since it was more commonly achieved in subjects with fewer co-morbidities and less extensive coronary disease.

Objectives: To study the association between CTO revascularization and survival in patients with uniform coronary anatomy consisting of isolated CTO of the right coronary artery (RCA).

Methods: A registry of 16,832 coronary angiograms was analyzed. We identified 278 patients (1.7%) with isolated CTO of the RCA who did not have lesions within the left coronary artery for which revascularization was indicated. Survival of 52 patients (19%) who underwent successful percutaneous coronary intervention was compared to those who did not receive revascularization.

Results: Revascularized patients were younger (60.2 vs. 66.3 years, P = 0.001), had higher creatinine clearance (106 vs. 83 ml/min, P < 0.0001), and had fewer co-morbidities than those who did not receive revascularization. Lack of CTO revascularization was a univariable predictor of mortality (hazard ratio [HR] = 2.65, 95% confidence interval [95%CI] 1.06–6.4) over 4.3 ± 2.5 years of follow-up. On multivariable analysis, the only predictors of mortality were increased age (HR 1.04, 95%CI 1.01–1.07), reduced creatinine clearance (HR 1.02, 95%CI 1.01–1.03), and ejection fraction below 55% (HR 2.24, 95%CI 1.22–4.11).

Conclusions: Among patients with isolated RCA CTO who underwent extended follow-up, revascularization was not an independent predictor of increased survival.

Background: The use of a high flow nasal cannula (HFNC) was examined for different clinical indications in the critically ill.

Objectives: To describe a single center experience with HFNC in post-extubation critical care patients by using clinical indices.

Methods: In this single center study, the authors retrospectively evaluated the outcome of patients who were connected to the HFNC after their extubation in the intensive care unit (ICU). At 48 hours after the extubation, the patients were divided into three groups: the group weaned from HFNC, the ongoing HFNC group, and the already intubated group.

Results: Of the 80 patients who were included, 42 patients were without HFNC support at 48 hours after extubation, 22 and 16 patients were with ongoing HFNC support and already intubated by this time frame, respectively. The mean ROX index (the ratio of SpO2 divided by fraction of inspired oxygen to respiratory rate) at 6 hours of the weaned group was 12.3 versus 9.3 in the ongoing HFNC group, and 8.5 in the reintubated group (P = 0.02). The groups were significantly different by the ICU length of stay, tracheostomy rate, and mortality.

Conclusions: Among patients treated with HFNC post-extubation of those who had a higher ROX index were less likely to undergo reintubation.

The authors reviewed the two most common current uses of brain 18F-labeled fluoro-2-deoxyglucose positron emission tomography (FDG-PET) at a large academic medical center. For epilepsy patients considering surgical management, FDG-PET can help localize epileptogenic lesions, discriminate between multiple or discordant EEG or MRI findings, and predict prognosis for post-surgical seizure control. In elderly patients with cognitive impairment, FDG-PET often demonstrates lobar-specific patterns of hypometabolism that suggest particular underlying neurodegenerative pathologies, such as Alzheimer’s disease. FDG-PET of the brain can be a key diagnostic modality and contribute to improved patient care.

We describe the features of nocebo, and its impact in studies of transition from the originator to the respective biosimilar in inflammatory rheumatic diseases. Investigations in healthy volunteers as well as in the neurology and anesthesiology fields demonstrated the involved cerebral areas and the neurotransmitter pathways responsible for the nocebo response. Whether these findings are applicable to patients with inflammatory rheumatic diseases remains to be demonstrated. Nocebo may account for part of the after-switching biosimilar failures. However, in the absence of validated classification or diagnostic criteria, specific neurochemical and neuroimaging studies, the lack of data on serum tumor necrosis factor and drug levels, and the disease improvement after the switching back to the originator biologic observed in some patients, the nocebo diagnosis remains the role of the individual clinician. Investigations on nocebo pathophysiology and diagnosis are required to address its impact in after-transition biosimilar studies in rheumatology.
