Background: Local anesthetics are used in various sites and mechanisms to maximize perioperative analgesia and reduce opioid use and side effects. Pain management in the bariatric setting is challenging and the efficacy of local anesthetics intraoperatively is under current evaluation.

Objectives: To determine the safety and efficacy of a new intra-abdominal anesthetic technique performed during laparoscopic bariatric operations: visceral block.

Methods: During this prospective randomized double-blinded pilot study, 16 patients undergoing bariatric surgery were treated with the injection of ropivacaine to the anterior esophagogastric junction fat, and 15 were injected with saline as control.

Results: The procedure was shown to be safe, and no adverse events nor side effects were encountered. A non-statistically significant trend toward the use of a non-opioid analgesia was documented during the first postoperative hours.

Conclusions: Visceral block is a safe and feasible intraoperative procedure. A trend toward its efficacy warrants future larger scale studies.

Gastric perforation secondary to foreign body ingestion is rare. While obvious signs of acute abdomen usually lead to a prompt diagnosis by emergency department (ED) staff, this can be delayed in non-responsive or mentally disabled patients. An altered pain perception has been described in schizophrenia, as part of a complex phenomenon, which is thought to be unrelated to changes in nociceptive pathways. Cognitive impairment and negative symptoms may strongly influence the patient’s expression of pain [1].

Background: Vitamin D is essential for skeletal health. Because peak bone mass accrual occurs during childhood and adolescence, vitamin D insufficiency during this period of life could cause adverse health outcomes.

Objectives: To explore the potential sex differences in anthropometric indicators and vitamin D status among primary school-age children.

Methods: A modified food-frequency intake questionnaire was completed by 116 pre-pubertal children (52 girls, 64 boys). Body measurements were recorded and blood was drawn to assess vitamin D status. All children were of Arab-Israeli origin and lived in villages or rural areas in the north-east area of Israel.

Results: Prevalence of obesity was higher among girls (34%) compared to boys (21.9%, P = 0.018). All the children were vitamin D insufficient, and 80% were deficient. Plasma vitamin D was significantly higher among boys (12.4 ng/ml) compared to girls (9.1 ng/ml, P < 0.01). A significant negative correlation was found between vitamin D status and weight percentile for girls (r = -0.43, P < 0.05) but not for boys. There was a trend toward a statistically significant inverse correlation between vitamin D status and body fat percent in the girls (r = -0.37, P = 0.07). Sex frameworks are important for the understanding of the determinants of health and the development of effective health promotion programs.

Conclusions: Pre-pubertal girls in Arab villages should be provided with tailor-made nutrition and physical activity programs for promoting health.

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: Endothelial progenitor cells may have a role in ongoing endothelial repair. Impaired mobilization or depletion of these cells may contribute to progression of vascular disease. Our hypothesis was that endothelial progenitor cells would be suppressed in patients with acute cerebrovascular event based on our previous study that found severe endothelial dysfunction in those patients.

Objectives: To study the ability of patients with acute stroke to build colonies of endothelial progenitor cells.

Methods: We studied the number of colony-forming units of endothelial progenitor cells (CFU-EPCs) from the peripheral blood of 22 male patients with a first-time acute stroke (age 58.09 ± 9.8 years) and 13 healthy men (34 ± 6.7 years), 8 female patients with a first-time acute stroke (54.6 ± 10.3 years) and 6 healthy women (38.3 ± 11.6 years). Endothelium-dependent function was assessed by high-resolution ultrasonography of the brachial artery that measured the change in diameter of the artery by flow-mediated diameter percent change (FMD%). All patients had strokes demonstrated by a brain computed tomography (CT) scan done on admission. Peripheral blood was drawn soon after admission and was processed for endothelial progenitor cells in culture.

Results: Thirty patients without known cardiovascular risk factors and who did not take any medications were admitted with a first-time acute stroke. All demonstrated a strong correlation between CFU-EPCs grown in culture and endothelial dysfunction (r = 0.827, P < 0.01). Endothelial dysfunction with an FMD% of -2.2 ± 9.7% was noted in male patients vs. 17.5 ± 6.8% in healthy males (P = 0.0001), and -7.2 ± 10.1% in female patients vs. 25.1 ± 7.1% in healthy females (P = 0.0001). CFU-EPCs were 5.5 ± 6.3 in men with stroke vs. 23.75 ± 5.3 in healthy males (P = 0.0001), and 7.6 ± 4.9 in women with stroke vs. 22.25 ± 6.7 in healthy females (P = 0.0004).

Conclusions: Patients with acute stroke had an impaired ability to grow CFU-EPCs in culture and exhibited endothelial dysfunction. The novelty of this study was the discovery of the phenomenon of depressed numbers of EPCs and the poor ability to grow colonies of EPCs in the first 24 hours of the cerebrovascular event.
