Background: Hookah smoking is a common activity around the world and has recently become a trend among youth. Studies have indicated a relationship between hookah smoking and a high prevalence of chronic diseases, cancer, cardiovascular, and infectious diseases. In Israel, there has been a sharp increase in hookah smoking among the Arabs. Most studies have focused mainly on hookah smoking among young people.

Objectives: To examine the association between hookah smoking and socioeconomic characteristics, health status and behaviors, and knowledge in the adult Arab population and to build a prediction model using machine learning methods.

Methods: This quantitative study based is on data from the Health and Environment Survey conducted by the Galilee Society in 2015–2016. The data were collected through face-to-face interviews with 2046 adults aged 18 years and older.

Results: Using machine learning, a prediction model was built based on eight features. Of the total study population, 13.0% smoked hookah. In the 18–34 age group, 19.5% smoked. Men, people with lower level of health knowledge, heavy consumers of energy drinks and alcohol, and unemployed people were more likely to smoke hookah. Younger and more educated people were more likely to smoke hookah.

Conclusions: Hookah smoking is a widespread behavior among adult Arabs in Israel. The model generated by our study is intended to help health organizations reach people at risk for smoking hookah and to suggest different approaches to eliminate this phenomenon.

We present an overview of the current sexual behavior of adolescents in Israel, including the related social and moral issues, and compare it to that in Western countries. An important factor is the existence of liberal versus conservative views regarding the use of contraception and termination of pregnancy in these young subjects. We describe the current situation where in most cases the medical providers do not provide adequate contraceptive advice to adolescent girls, resulting ultimately in a high rate of unintended pregnancy. In our opinion, it is essential to make effective contraception more accessible to this vulnerable group.

Background: Genetic factors have been shown to play a major role in the development of peak bone mass, with hereditability accounting for about 50-85% of the variance in bone mass. Numerous candidate genes were proposed to be involved in osteoporosis, but the precise genes and their relative contribution remain unknown.

Objectives: To gain insight into the genetic basis of idiopathic low bone mineral density in Israeli patients by analyzing the impact of two candidate genes: polymorphism of the vitamin D receptor gene and polymorphism A986s in the calcium-sensing receptor gene.

Methods: We analyzed 86 Jewish Israeli patients with LBMD[1]: 38 premenopausal women and 48 men, and compared the allelic pattern distribution with that of the general population (126 men and 112 women). Genotyping of the VDR[2] gene was performed in three polymorphic sites using restriction enzymes, and allelic analysis of A986s polymorphism in the CaSR[3] gene was performed using the denaturing gradient gel electrophoresis technique.  

Reaults: In LBMD women the distributions of VDR alleres in Apal polymorphism were AA=7/28, Aa=16/28 and aa=5/28; in TaqI polymorphism TT=10/31, Tt=16/31 and tt=5/31; and in BsmI polymorphism BB=7/32, Bb=14/32 and 11/32. In LBMD men the distributions were AA=17/39, Aa=21/39 and aa=1/39; in TaqI polymorphism TT=12/42, Tt=23/42 and tt=7/42; and in BsmI polymorphism BB=12/41 Bb=18/41 and bb=11/41. The distributions of all these polymorphisms in the control groups were not significantly different. Adjusting for the independent age and gender parameters confirmed that these three polymorphisms of the VDR gene did not have a significant effect on bone mineral density. Thirty percent (24/79) of LBMD patients of either sex displayed heterozygosity of the CaSR A986s polymorphism, compared with 40 of 203 controls (19.7%) (P=0.059). Adjusting for age and gender in these patients revealed a significant difference in the femoral neck BMD[4] between homozygotes and heterozygotes (P=0.002). The age at menarche of the LBMD women was found to predict 61% of the variance of femoral neck BMD.

Conclusions: In Israeli Jewish men and premenopausal women VDR gene alleles do not seem to be associated with lower lumbar spine or femoral neck BMD. A trend towards heterozygosity for a CaSR polymorphism missense mutation was noted in the LBMD patients. Age at menarche in the LBMD women was found to be an important predictor of BMD. A significant difference was found between LBMD women and healthy control women towards heterozygosity for a CaSR polymorphism, as well between homozygotes and heterozygotes for a CaSR polymorphism in BMD. The significance of these findings and their applicability to a larger population awaits further studies.

Background: Pregnant diabetic women are often subjected to frequent and prolonged hospitalizations to assure tight glycemic control, but in recent years attempts have been made at ambulatory control. The financial and social advantages of ambulatory management are obvious, but no report to date has prospectively compared its efficacy with that of hospitalization.

Objectives: To evaluate the efficacy and cost of ambulatory care as compared to repeated hospitalizations for management of diabetes in pregnancy.

Methods: We conducted an 8 year prospective controlled study that included 681 diabetic women, experiencing 801 singleton pregnancies, with commencement of therapy prior to 34 gestational weeks. During 1986–1989, 394 pregnancies (60 pre-gestational diabetes mellitus and 334 gestational diabetes mellitus) were managed by hospitalization, and for the period 1990–1993, 407 pregnancies (61 PGDM and 346 GDM) were managed ambulatorily. Glycemic control, maternal complications, perinatal mortality, neonatal morbidity and hospital cost were analyzed.

Results: There was no difference in metabolic control and pregnancy outcome in women with PGDM between the hospitalized and the ambulatory groups. Patients with GDM who were managed ambulatorily had significantly lower mean capillary glucose levels, later delivery and higher gestational age at induction of labor as compared to their hospitalized counterparts. In this group there were also lower rates of neonatal hyperbilirubinemia, phototherapy and intensive care unit admissions and stay. The saved hospital cost (in Israeli prices) in the ambulatory group was $6,000 and $15,000 per GDM and PGDM pregnancy, respectively.

Conclusions: Ambulatory care is as effective as hospitalization among PGDM patients and more effective among GDM patients with regard to glycemic control and neonatal morbidity. This is not only more convenient for the pregnant diabetic patient, but significantly reduces treatment costs.
