Background: Depending on the definition used, malnutrition is prevalent among 20¨C50% of hospitalized patients. Routine nutritional screening is necessary to identify patients with or at increased risk for malnutrition. The Nutrition Risk Screening (NRS 2002) has been recommended as an efficient tool to identify the risk of malnutrition in adult inpatients.
Objectives: To utilize the NRS 2002 to estimate the prevalence of malnutrition among newly hospitalized adult patients, and to identify risk factors for malnutrition.
Methods: During a 5 week period, all adult patients newly admitted to all inpatient departments (except Maternity and Emergency) at Wolfson Medical Center, Holon, were screened using the NRS 2002. An answer of yes recorded for any of the Step 1 questions triggered the Step 2 screen on which an age-adjusted total score ¡Ý 3 indicated high malnutrition risk.
Results: Data were obtained from 504 newly hospitalized adult patients, of whom 159 (31.5%) were identified as high risk for malnutrition. Malnutrition was more prevalent in internal medicine than surgical departments: 38.6% vs. 19.1% (P < 0.001). Body mass index was within the normal range among subjects at high risk for malnutrition: 23.9 ¡À 5.6 kg/m2 but significantly lower than in subjects at low malnutrition risk: 27.9 ¡À 5.3 kg/m2 (P < 0.001). Malnutrition risk did not differ by gender or smoking status, but subjects at high malnutrition risk were significantly older (73.3 ¡À 16.2 vs. 63.4 ¡À 18.4 years, P < 0.001). Total protein, albumin, total cholesterol, low density lipoprotein-cholesterol, hemoglobin and %lymphocytes were all significantly lower, whereas urea, creatinine and %neutrophils were significantly higher in patients at high malnutrition risk.
Conclusions: Use of the NRS 2002 identified a large proportion of newly hospitalized adults as being at high risk for malnutrition. These findings indicate the need to intervene on a system-wide level during hospitalization.

Background: The incidence of invasive disease due to Haemophilus influenzae has decreased since the implementation of vaccination against serotype B.
Objectives: To describe the epidemiology, clinical and microbiological characteristics of patients with H. influenzae meningitis or bacteremia in the vaccine era in Israel.
Methods: We reviewed the medical records of all patients admitted to Shaare Zedek Medical Center between 1997 and 2010 who had blood or cerebrospinal fluid culture positive for H. influenzae.
Results: The study group comprised 104 patients – 57 children and 47 adults. Overall, 21 (20%) of the infections were due to serotype b. The children had shorter hospitalizations (6 vs. 12 days, P = 0.005) and lower mortality rate (5% vs. 28%, P = 0.003) as compared to the adults. Bacteremic pneumonia was the most common diagnosis in adults (45% vs. 28% in children, P = 0.08) while meningitis was more common in children (17% vs. 3.5%, P = 0.09). There was a seasonal pattern, with infections being more common during the winter and spring.
Conclusions: Invasive H. influenzae disease is uncommon but still exists in both children and adults. The disease course tends to be more severe in adults. Even in the global vaccination era, serotype b constitutes a significant portion of invasive disease.

Background: Overuse and abuse of antibiotics is a major cause of microbial resistance. Within the hospital setting such overuse necessitates real-time supervision by infectious diseases (ID) specialists.
Objectives: To evaluate the impact of a recently introduced computerized antibiotic authorization system on the pharmacy budget.
Methods: The study was performed in a 400 bed university hospital. With the new system, antibiotic requests are entered electronically by the ward physician and reviewed within minutes to hours by ID specialists. The feedbacks are seen in the wards and pharmacy. Successive years, one before and the other after introduction of the system, were compared.
Results: During the first year with the new system 7167 antibiotic requests were entered 20% of them were rejected, mainly for improper indication (43% of the rejections). During that year the antibiotic expenditure was reduced by 17%, compared to the previous year (~equal to 200,000 US$), and was against the trend of the last 5 years. Of the 35 antibiotics under the control of the ID team, the use of 7 was probably curtailed by the supervision. Pareto analysis revealed that four drugs constituted > 50% of the pharmacy’s expenses. The mortality rate (per 1000 hospitalization days) during those 2 years fell from 4.0 to 3.8.
Conclusions: Computerized antibiotic control by ID specialists is a feasible cost-saving new modality that may help reduce unnecessary antibiotic prescriptions.

The “Israeli Paradox“ (1996) of low national health rankings despite adequate diet – attributed to high dietary n-6 polyunsaturated fatty acids (PUFA) – coincided with long-observed dichotomies between women’s worse international status vs. men’s advantage. This raised the assumption of a gender link to high n-6 risk as an explanation for both national phenomena. Israeli women’s disadvantage was shown by worse international rankings, i.e., life expectancy (LE), 11th vs. men’s 3rd-best/22 countries (2000), and 14th vs. 6th/34 (2010) all-cause and all-cancer mortality both 15th vs. 2nd-best/22 (2000), and 15th vs. 6th/22 and 12th vs. 2nd-best/22 (2010). Breast cancer mortality rates were +21.8%, vs. prostate -30.4%, compared to Eur-A (27 country) averages (2005). Gender gaps/ratios were smaller than European Union-15, i.e., LE at birth by 34.4–26.4% (2000–2010), respectively, and at 65 years 45.9–35.3% all-cause mortality by 43.3–33.4%, and all-cancer 65.2–58.7%. The Israeli diet was mostly close to guidelines, but n-6 intake (10–12% kcal) was much higher than both recommended and traditional “Mediterranean diet“ levels. Research showing females’ greater potential for conversion of PUFA to long-chain PUFA (LCPUFA) may suggest their potentially increased production of n-6 eicosanoids with known pro-inflammatory/oxidative/carcinogenic potential. An “N-6 Gender Nutrition Paradox“ hypothesis is suggested here, for the first time, associating women’s higher risk and lead in the national “paradox“ with greater potential for n-6 conversion to pro-inflammatory/oxidative/carcinogenic eicosanoids compared to men. This may also exacerbate women’s risk associated with genetic predisposition (i.e., BRCA) and/or sociopolitical stress. Global abandonment of traditional diets/foods together with increasing n-6 consumption and western disease rates emphasize the importance of considering gender in nutritional epidemiology and preventive strategies.
