Since the Surviving Sepsis Campaign Guideline (SSG) was published in 2004, critical care physicians can readily access the evidence and current recommendations regarding management of patients with severe sepsis and septic shock. However, several issues including a potential conflict of interest in developing the guidelines were disclosed. There have also been dramatic changes in the management of sepsis, supported by high levels of evidence. SSG[1] 2008 was developed to update the evidence using a new grading system. We reviewed select topics, routinely addressed by intensivists in the surgical intensive care unit, that have changed between SSG 2004 and SSG 2008: namely, glucose control, and administration of steroids, recombinant human activated protein C (rhAPC) and total parenteral nutrition.

Background: Enteral nutrition in the critically ill patient is often complicated by gastrointestinal intolerance, manifested by a large gastric residual volume. The frequency of GRV[1] assessment and the intolerant level above which feeding is stopped is controversial.

Objectives: To evaluate a novel approach to EN[2] by allowing high GRV and once-daily assessment that was correlated with the paracetamol absorption test.

Methods: We conducted a pilot prospective study in an 18 bed general intensive care unit. The study group comprised 52 consecutive critically ill mechanically ventilated patients. Enteral nutrition was started at full delivery rate. Once-daily assessment of GRV with three consecutively repeated threshold volumes of 500 ml was performed before stopping EN. The paracetamol absorption test was performed and correlated to GRV. Patients were divided into two groups: low GRV (< 500 ml), and high GRV (at least one measurement of GRV > 500 ml). Clinical outcome included maximal calories delivered, incidence of pneumonia, ICU[3] length of stay, and ICU and hospital mortality.

Results: There were 4 patients (9.5%) with ventilator-associated pneumonia in the low GRV group and 3 (30%) in the high GRV group (P = 0.12). GRV was inversely correlated to paracetamol absorption; however, neither GRV nor paracetamol absorption was associated with the development of pneumonia. Both groups had similar ICU length of stay (11.0 ± 8.2 vs. 13.8 ± 14.4 days, P = 0.41), and similar ICU (21% vs. 40%, P = 0.24) and hospital mortality (35% vs. 40%, P = 1.0).

Conclusions: In critically ill mechanically ventilated patients, allowing larger gastric residual volumes, measured once daily, enables enteral feeding with fewer interruptions which results in high calorie intake without significant complications or side effects.

Background: The rates of anemia in children in southern Israel are high despite the current prevention strategy. A daily dose of Sprinkles (SuppleForteTM, Heinz, Canada), a micronutrient home supplementation, was proven effective for the treatment of anemia worldwide.

Objectives: To assess the efficacy of Sprinkles, a novel supplementation formulation, in the primary prevention of anemia in infants who have free access to health care services. Methods: A two-arm open-labeled cluster randomized controlled clinical trial was performed in 6 month old Bedouin and Jewish infants. The Sprinkles arm received sachets with iron, vitamins A and C, folic acid and zinc, and the control arm received standard treatment (liquid iron and vitamins A and D). The infants were from families attending Maternal and Child Health clinics during 2005–2008. Intervention and follow-up were conducted for babies aged 6–12 months. Health outcomes (hematologic and nutritional indicators, growth parameters, morbidity rates) were evaluated at 12 and 18 months.

Results: The final study population numbered 621 infants (328 Bedouin and 293 Jewish) of the parents approached 88.5% agreed to participate. Hemoglobin above 11 g/dl was found in 55% of Bedouin and 40% of Jewish infants (P < 0.01). Bedouin infants had significantly lower serum concentration of iron, folic acid and zinc. All background, hematologic and micronutrient indicators were similar in the two study arms except for a slightly but not clinically significant difference in hemoglobin and hematocrit levels in Bedouins.

Conclusions: Our findings indicate the need to improve the micronutrient status of infants living in the Negev. A cluster randomized trial in MCH[1] clinics is a feasible option.

Background: A polymeric diet rich in transforming growth factor-beta 2 used as a single nutrient has been shown to induce remission in 79% of children with Crohn's disease.

Objectives: To summarize the experience of several pediatric gastroenterology units in Israel using a TGFβ2[1]-enriched polymeric diet (Modulen IBD) supplementation in children and adolescents with Crohn's disease.

Methods: In a retrospective study we reviewed the charts of 28 children with Crohn's disease (10 girls, 18 boys) who received, in addition to conventional treatment, Modulen IBD™ as a supplement to their regular nutrition. These children were compared with 18 children supplemented with standard polymeric formula (Ensure Plus®) and 18 children without formula supplementation. We recorded clinical manifestations, growth, and the Pediatric Crohn's Disease Activity Index before and after initiation of the polymeric diet.

Results: The Modulen-treated children showed a significant decrease in PCDAI[2] from 34.3 to 15.7 (P < 0.0001). A significant decrease in PCDAI was recorded also in the Ensure Plus group, from 35 to 22 (P = 0.02) but not in the non-supplemented group. Significant improvements in body mass index (P = 0.01) and erythrocyte sedimentation rate (P = 0.03) were recorded at follow-up (median 3.4 months) only in the Modulen IBD group.

Conclusions: In this cohort of children with Crohn's disease, supplementation of the diet with Modulen IBD as well as supplementation with Ensure Plus was associated with a decrease in PCDAI. The children supplemented with Modulen IBD also showed improvement in BMI[3], suggesting an additional advantage of nutritional therapy in children with this disease.

Background: It has been suggested that increased calcium intake plays a role in preventing obesity and promoting weight loss.

Objectives: To assess the association between calcium intake, body mass index and waist circumference in Israel.

Methods: MABAT is a cross-sectional survey based on a random sample of 3246 Israelis aged 25 to 64. Of the 3246 survey participants, height and weight measurements were recorded for 2782 (1371 men and 1411 women). These were divided into three groups according to their BMI[1] (group A ≤ 24.9, group B 25–29.9, and group C ≥ 30) and given a 24 hour food consumption recall questionnaire. Waist circumference was measured in 2601 participants (1760 men and 841 women) and was considered to be excessive if ≥102 cm for men or 88 cm for women.

Results: The mean calcium intake was 511.5 ± 301.8 mg for group A, 499.4 ± 283.7 mg for group B, and 464.7 ± 280.1 mg for group C (group A significantly differed from group C, P < 0.002). The mean daily milk consumption in group A was higher than in groups B and C (103.4 ± 147.5, 85.7 ± 122.25, and 84.5 ± 135.1 g, respectively; P < 0.01). There was no correlation between daily dietary calcium intake and waist circumference for men but women with a waist circumference below 88 cm consumed significantly more dietary calcium than those with a waist circumference ≥ 88 cm (P < 0.03).

Conclusions: The study confirms the inverse relationship between daily dietary calcium intake and obesity. This linkage relates to the intake of milk, but not to other dairy products.

Background: As high dietary n-6 polyunsaturated fatty acids and n-6:n-3 PUFA[1] ratio may contribute to many western ailments, increasing n-3 PUFA in foods could be beneficial. The nutritional significance of n-3 PUFA-fortified egg vs. enzymatically competitive high n-6 PUFA diets is debatable.

Objectives: To evaluate the dietary contribution of 'field fortification' of eggs by adding n-3 PUFA to high n-6 PUFA hen feed and whether it meets consumer preferences.

Methods: Laying hens (n=3500) were fed n-3 PUFA-fortified (5% extruded linseed) feed or standard (control) feed for 5 weeks. Nutritional significance was evaluated for western (American, Israeli) populations.

Results: Compared to regular (control) eggs, fortified eggs yielded a 3.8-fold increase in total n-3 PUFA, 6.4-fold alpha-linolenic acid (18:3), and 2.4-fold docohexaenoic acid 22:6). N-6:n-3 PUFA ratio decreased 3.6-fold, and n-6:n-3 long chain PUFA ratio threefold (P < 0.0003). Sensory evaluations were not significantly different. Egg cost increased by 1.0–1.5%. Fortified egg n-3 PUFA content averaged 14.3% of the current intake of Americans and 15.9% of Israelis – 9.8 and 10.5% of upper Dietary Reference Intakes, respectively. Egg DHA content averaged 32.9 and 41.1% of upper DRI[2]. Current cholesterol intakes average 281 and 263 mg/day (median 214 and 184 mg/day) including 0.7 and 0.5 egg/day; reported hypercholesterolemia rates are 17.7 and 16.5%, respectively.

Conclusions: Effective concentration and transformation of supplemental n-3 PUFA/LCPUFA[3] from feed to egg substantially enhanced egg n-3 PUFA %DRI, particularly of DHA[4], critical for health but often deficient. Such land-based n-3 PUFA/LCPUFA fortification may be applicable to high n-6 PUFA diets, fitting within cholesterol limitations and market criteria. It may contribute to general health and specific requirements (i.e., pregnancy and lactation), with possibilities of wide accessibility and standardization.

Premature very low birth weight (< 1500 g) infants are one of the largest groups receiving parenteral nutrition. PN[1] should be optimized to answer their large nutritional requirements and suit their metabolic status, but should also be validated pharmaceutically. PN can be provided as a standard, usually commercial, formulation, representing the average needs of a large group of patients. Alternatively, an individualized PN compound adapted to the patient's needs can be prescribed and prepared, usually on a daily basis. The main advantage of individually prescribed PN is that it is tailored to suit a specific patient, thereby assuring the best possible nutrition and biochemical control. Batch-produced standardized PN bags can be readily available as ward stocks in neonatal intensive care units, enabling initiation of early PN immediately after the delivery of a premature infant. Moreover, standard PN solutions incorporate expert nutritional knowledge and support. A combination of standardized PN bags, prepared under strict standardization criteria, for most neonates, with a small number of specifically tailored individualized PN formulations for those in need for them, could reduce pharmacy workload and costs, and increase safety, while maintaining the desired clinical flexibility. For those in need of the individualized PN formulations, a computerized ordering system can save time, decrease prescription and compounding errors, and improve quality of nutritional care.

Background: Food allergies in children are often very serious and can lead to anaphylactic reactions. Observations that camel milk ameliorates allergic reactions were noted over the years. The effect of the camel milk is probably related to its special composition.

Objectives: To investigate the effect of camel milk in several children with severe food (mainly milk) allergies.

Methods: We studied eight children with food allergies who did not benefit from conventional treatment. Their parents, or their physicians, decided to try camel milk as a last resort. The parents were advised by the authors – who have considerable experience with the use of camel milk – regarding how much and when the children should drink the milk. The parents reported daily on the progress of their children.

Results: All eight children in this study reacted well to the milk and recovered fully from their allergies.

Conclusions: These encouraging results should be validated by large-scale clinical trials.

Background: The prevalence of obesity has increased considerably in many countries in recent decades.

Objective: To describe the prevalence of overweight and obesity in the Israeli population, based on findings of the first national health and nutrition survey (MABAT).

Methods: This cross-sectional survey was carried out during 1999–2000. MABAT is based on a representative sample (n=3,246) of the general Israeli population aged 25–64 years. The current study population comprised those with complete data on measured weight and height (n=2,781). Participants were interviewed in person and had their weight and height measured by the interviewer.

Results: Over 50% of the study participants were women (n=1,410); 76% were Jews and 24% Arabs. Most participants had an education of at least 12 years (72%). Body mass index ≥30.0 was more prevalent in women compared to men (P < 0.001) in both population groups (Jews and Arabs). Obesity rates increased with age and reached 22.4% for men and 40.4% for women aged 55–64 years. Lower education was associated with higher obesity rates, with lowest rates observed for Jewish women with an academic education (13.6%) and highest rates observed for Arab women with a basic education (57.3%). Multiple logistic regression analyses showed age to be a significant risk factor in men. Age, education and origin (Arab, and the former Soviet Union for Jews) were significant risk factors for obesity in women.

Conclusions: Obesity rates in Israel are high and comparable to those in the United States. Of special concern is the subgroup of older Arab women (55–64 years), whose obesity rates reached 70%.
