Abstract
Objective: This study aimed to describe Israeli maternity departments’ policies regarding cesarean delivery on maternal request, and factors associated with obstetricians’ support for cesarean delivery on maternal request in specific scenarios. Methods: This multicenter cross-sectional study included 22 maternity department directors and 222 obstetricians from the majority of Israeli hospitals. Directors were interviewed and completed a questionnaire about their department’s cesarean delivery on maternal request policy, and obstetricians responded to a survey presenting case scenarios in which women requested cesarean delivery on maternal request. The scenarios represented profiles referring to the following factors: maternal age, poor obstetric history, pregnancy complications, and psychological problems. The survey also included the obstetricians’ socio-demographic information and questions about other issues associated with cesarean delivery on maternal request. The main outcome measures were department policies regarding cesarean delivery on maternal request and obstetricians’ support for cesarean delivery on maternal request in specific cases. Results: Policies were divided between allowing and prohibiting cesarean delivery on maternal request (n = 10 and 12, respectively), and varied regarding issues such as informed consent and pre-surgery consultation. Most of the obstetricians (96.5%) did not support cesarean delivery on maternal request in the “reference scenario” describing a young woman with no obstetric complications. Additional factors increased the rate of support. Support was greater among obstetricians aged > 45 (odds ratio = 2.11; 95% confidence intervals 1.33–3.36) and lower among females (odds ratio = 0.58; 95% confidence intervals 0.39–0.86). Obstetricians whose department policy was less likely to allow cesarean delivery on maternal request reported lower rates of support for cesarean delivery on maternal request in most cases. Conclusion: Policies and obstetricians’ support for cesarean delivery on maternal request vary broadly depending on clinical profiles and physician characteristics. Department policy has an impact on obstetricians’ support for cesarean delivery on maternal request. Health policy will benefit from a framework in which the organizations, physicians, and patients are consulted.

Abstract
BACKGROUND Preterm infants are at high risk for long-term morbidities and an increased rate of re-hospitalization. OBJECTIVE The aim of this study was to evaluate the type of re-hospitalization of very low birth weight (VLBW) infants, from infancy through adolescence, and to assess the association of neonatal morbidities with specific types of re-hospitalization. STUDY DESIGN The study cohort comprised 6,385 VLBW infants who were registered with the Maccabi Healthcare Services (MHS) from their birth hospitalization. Data were collected for up to 18 years (median 10.7 years) following neonatal intensive care unit discharge. Hospitalization types were determined from the MHS coding. Neonatal morbidities included necrotizing enterocolitis (NEC), grades 3-4 intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL), bronchopulmonary dysplasia (BPD), and retinopathy of prematurity (ROP). Adjusted hazard ratios (aHR) and 95% confidence intervals (CI) were calculated using the Cox proportional hazards model. RESULTS Overall, 3,956 infants were re-hospitalized at least once and a total of 11,595 hospitalization types were identified. NEC, IVH, PVL, and BPD were associated with significantly higher aHRs for general pediatric (aHR 1.28-1.55), general surgical (aHR 1.18-1.46), and pediatric intensive care unit (aHR 1.57-2.04) hospitalizations. IVH and PVL were associated with significantly higher aHRs for orthopedic (aHR 2.12 and 4.88, respectively) and ophthalmology (1.76 and 4.02, respectively) hospitalizations. IVH was associated with a 14.2-fold higher aHR for neurosurgical admissions, and ROP with a 1.62-fold higher aHR for ophthalmology hospitalizations. CONCLUSION Among VLBW infants, specific patterns of re-hospitalization types associated with major neonatal morbidities were identified as particularly high risks for orthopedic and ophthalmology hospitalizations in infants with IVH and PVL, and for intensive care admissions in infants with NEC and BPD.

Abstract
One of the ways to reduce the pesticidal burden in mature ampelocenoses is the use of foliar bio-preparations of multifunctional action. We studied the influence of growth bioregulators “Albit” and “Mival-Agro” at reduced by 25–50% fungicidal load on productivity and phenolic complex composition (using the HPLC method) of Vitis vinifera “Asma” (Crimean autochthonous table cultivar), “Cabernet Sauvignon” and table grapes of complex genetic structure “Moldova”, grown in the mountain-valley seaside region of Crimea. It was established that bio-regulators increase the harvest of grapes, especially in the first and third years of treatment, depending on the preparation and grape cultivar, by 27–64% and 24–29%, respectively, as compared to control; the bunch weight increased by 134 ± 41%. The first two years of treatment enhance sugar accumulation in berries by 0.7–2.6 Brix. “Albit” preparation proved to be more effective as compared to “Mival-Agro”. The use of “Albit” on “Moldova” and “Cabernet Sauvignon” grapes increased components content in the berries by 19%–88% relative to control, depending on the cultivar and year of treatment, of which: anthocyanins – by 23–83%, stilbenes – by 24–138%. Regardless of treatment, the anthocyanin complex consisted by 75–87% of malvidin monoglucosides in “Cabernet Sauvignon” and “Asma”; 22–56% of malvidin monoglucosides and 21–62% of malvidin diglucoside in “Moldova”. The studied preparations had no significant impact on the quality of wines from “Cabernet Sauvignon”, however, they improved the quality of table grapes and their preservation capacity during storage.

Abstract
UNLABELLED Wide disparities in knowledge of risk factors and prevention of osteoporosis were demonstrated among midlife Israeli minority women (Arabs and immigrants from the former USSR) compared to Jewish long-time residents. Women who believed osteoporosis to be a serious disease and those who felt susceptible to it reported better knowledge. PURPOSE The main goals of this study were to assess knowledge of risk factors and preventive measures for osteoporosis in middle-aged women and to evaluate the relationship of knowledge to personal risk factors and personal perceptions about osteoporosis. METHODS Face-to-face interviews with women aged 45-64 years were conducted during 2004-2006 within three population groups: long-term Jewish residents (LTJRs), immigrants from the former Soviet Union, and Arab women. The survey instrument included five knowledge statements related to the risk after menopause, the risk of smoking, family history of fractures, decreased risk by physical activity, and by use of medications. RESULTS The findings indicated wide disparities in knowledge about risk factors and preventive behavior of osteoporosis between the two minority groups (immigrants from the former Soviet Union and Arab women) and the majority group of midlife Israeli women. Knowledge of osteoporosis was related to perceived severity of the disease and partly to perceived susceptibility to osteoporosis. Past diagnosis of osteoporosis, current or past smoking status, and BMI were unrelated to knowledge in multivariate analyses. CONCLUSIONS There is a need to improve knowledge of osteoporosis especially among less educated and minority women. Subjective perception of risk was more strongly related to knowledge than actual risk factors and should be targeted in public campaigns. The efforts should be aimed at strengthening women's perception of their own susceptibility to osteoporosis and of the severity of this disease.

Abstract
The research is based on the results of the examination and treatment of 156 patients who received treatment for extended benign esophageal strictures after corrosive injuries in the department of diseases of the esophagus and the gastrointestinal tract of the State Institution "V. T. Zaitsev Institute of General and Urgent Surgery of NAMS of Ukraine" for the period from 2000 to 2016. Surgical treatment by the developed in our hospital technique performed in the patients of the main group and the classical methods of surgery were used in the patients of comparison group. The developed in our clinic method of one-step transhital esophagogastroplasty with formation of a single anastomosis on the neck in patients with extended benign esophageal strictures after corrosive injuries in the state of compensation and subcompensation can be considered as a method of choice. Adequate preoperative verification of the type of extended damage by the cicatricial process of the upper part of digestive tract and the impossibility of eating in a natural way in the acute postburn period, as well as significant nutritive disorders in patients, provide the basis for two-step surgical treatment. This approach involves formation of gastrostomy at the first step for the restoration of trophological status of the patient and esophagoplasty at the second step. The two-step surgical treatment of patients with extended benign esophageal strictures after corrosive injuries with the formation of contact gastrostomy at first step and the implementation of esophagogastroplasty on the second step promotes improvement of treatment outcomes and life quality of the operated patients.

Abstract
The objective of the study was the structural analysis of the 70TeO2-5XO-10P2O5-10ZnO-5PbF2 (X = Mg, Bi2, Ti) tellurite glasses doped with ions of the rare-earth elements Er3+, based on the PALS (positron annihilation lifetime spectroscopy) method of measuring positron lifetimes. Values of positron lifetimes and the corresponding intensities may be connected with the sizes and number of structural defects, the sizes of which range from a few angstroms to a few dozen nanometers. Experimental positron lifetime spectrum revealed existence of two positron lifetime components τ 1 andτ 2. Their interpretation was based on two-state positron trapping model where the physical parameters are the positron annihilation rate and positron trapping rate.

Abstract
OBJECTIVE To evaluate the impact of major neonatal morbidities on the risks for rehospitalization in children and adolescents born of very low birth weight. STUDY DESIGN An observational study was performed on data of the Israel Neonatal Network linked together with the Maccabi Healthcare Services medical records. After discharge from the neonatal intensive care unit, 6385 infants of very low birth weight born from 1995 to 2012 were registered with Maccabi Healthcare Services and formed the study cohort. Multivariable negative binomial regression models were calculated to estimate the adjusted relative risk (aRR) and 95% CI for hospitalization. RESULTS Up to 18 years following discharge, 3956 infants were hospitalized at least once. The median age of follow-up was 10.7 years with total of follow-up of 67 454 patient years and 10 895 hospitalizations. The risks for rehospitalization were increased significantly for each of the neonatal morbidities: surgical necrotizing enterocolitis (NEC), aRR 2.71 (95% CI 2.08-3.53), intraventricular hemorrhage grades 3-4, 2.13 (1.85-2.46), periventricular leukomalacia (PVL), 1.83 (1.58-2.13), bronchopulmonary dysplasia, 1.94 (1.72-2.17), and retinopathy of prematurity stages 3-4, 1.59 (1.36-1.85). During the first 4 years, children with surgically treated NEC, intraventricular hemorrhage, PVL, or bronchopulmonary dysplasia had 1.5- to 2.5-fold greater risks for hospitalization compared with those without the specific morbidity. In the 11th-14th and 15th-18th years, respectively, surgically treated NEC was associated with a 3.05 (1.32-7.04) and 3.26 (0.99-10.7) aRR for hospitalization, and PVL was associated with a 2.67 (1.79-3.97) and 3.47 (2.03-5.92) aRR for hospitalization. CONCLUSIONS Specific major neonatal morbidities as well as the number of morbidities were associated with excess risks of rehospitalization through childhood and adolescence.

Abstract
The early stages of silica polymerization in aqueous solution proceed according to a mechanism based on three steps: nucleation, particle growth, and agglomeration of the particles. Application of time-resolved static and dynamic light scattering as a powerful in situ technique in combination with spectrophotometric analysis of the monomer consumption based on the molybdenum blue method was carried out to further investigate this 3-step process. Experiments were carried out at four different initial silicic acid contents covering a range between 350 and 750 ppm in the presence of either 10 mM NaCl or 5 mM of a mixture of CaCl2 and MgCl2. The process in all cases was initiated with a drop of pH to 7. Addition of the salts made possible an analysis of the impact of an electrolyte on the process. Independent of the presence or absence of salt, particle growth in step two proceeded as a monomer-addition process without being interfered significantly by Ostwald-ripening. The growing particles were compact with a homogeneous density. The size of the particles approached final values between 5 and 20 nm with the actual value increasing with decreasing initial silicic acid content. Above a certain concentration of initial silica content, which depends on the level of added salt, particle-particle interactions caused agglomeration. The presence of electrolyte shifted this level from ∼2000 ppm to a range between 500 and 750 ppm. The resulting agglomerates had a fractal dimension of 2. Independent of the conditions, particle growth could be described with a simple nucleation and growth model.

Abstract
BACKGROUND Among children conceived by assisted reproductive technology (ART), increased risk of adverse birth outcomes has been observed, including multiple births, preterm births, and congenital malformations. Regarding cancer among ART-conceived children, findings are discrepant. METHODS This is a historical cohort of 9,042 ART-conceived children and 211,763 spontaneously conceived (SC) children born from 1997 through 2004. The median duration of follow-up was 10.6 years (interquartile range 9.0-12.3) in the ART group and 9.3 years (interquartile range 8.0-10.6) in the SC group. The cohort database was linked with the Israel National Cancer Registry updated until December 31, 2011 using each child's personal identification number. RESULTS Twenty-one cases of cancer were identified in the ART group (2.2 per 10,000 person-years), as compared to 361 cancer cases in the SC group (1.8 per 10,000 person-years). The relative risk (RR) for overall cancer in the ART group compared to the SC group adjusted for maternal characteristics was 1.18 (95% confidence interval [CI] 0.80-1.75). ART children had a significantly increased risk for specific cancers, although based on small number of cases, including two cases of retinoblastoma (RR 6.18, 95% CI 1.22-31.2), as well as four cases of renal tumors (RR 3.25, 95% CI 1.67-6.32). CONCLUSION A statistically significant increased risk for two pediatric cancers was found. However, for overall types of cancer the risk estimate was elevated but not statistically significant. Further studies with larger sample size and longer follow-up time are warranted in order to either confirm or refute these findings.

Abstract
BACKGROUND Sexual lifestyles including sexual activity, problems, satisfaction, and the formation and maintenance of relationships are greatly affected by physical health. Data are limited regarding the sexual lifestyle of adolescents and young adults with type 1 diabetes mellitus (T1DM). Fear of hypoglycemic episodes during sexual intercourse and intimacy issues can impact individuals with T1DM. The aim of this study was to assess sexual lifestyles of individuals with T1DM. METHODS Fifty-three patients with T1DM, 27 (51%) males, mean ± SD age 27.9 ± 8.3 years completed the Hypoglycemia Fear Survey-II and the Sex Practices and Concerns questionnaire. RESULTS Thirty-seven (70%) reported they never or almost never had concerns in their sexual lifestyles that were related to their diabetes. None experienced severe hypoglycemia during sex, but 21 (40%) reported occasional mild hypoglycemic events. More than two-thirds do not take any measures to prevent hypoglycemia before sex (decreasing insulin dose, snacks, and measuring blood glucose levels). Fear of hypoglycemia during sex was reported by 18 (35%); those who reported increased fear experienced mild hypoglycemic events during sex (61.1% vs 26.5%, P = .01), were singles (94.4% vs 64.7%, P = .02), and had higher scores on the Worries subscale of the Hypoglycemia Fear Survey-II (42.8 ± 12.8 vs 34.9 ± 10.5, P = .04) compared with those who did not. CONCLUSIONS Among young people with T1DM, most do not have concerns regarding sex that are related to their diabetes, and most do not take specific measures before or after sex. One-third, however, fear of hypoglycemia during sex, mostly singles and those who experienced hypoglycemia in the past. Caregivers should be aware and address these concerns.

Abstract
AIM To evaluate the possible association between major neonatal morbidities and poor head growth from birth to discharge home in very-low-birthweight (VLBW) infants born preterm. METHOD Population-based observational study comprising 12 992 infants (6340 male, 6652 female) of 24 to 32 weeks' gestation, and birthweight ≤1500g. Severe head growth failure (HGF) was defined as a decrease in head circumference z-score >2 z-scores, and moderate HGF as a decrease of 1 to 2 z-scores. Multinomial logistic regression analysis was applied to determine morbidities associated with HGF. RESULTS Severe HGF occurred in 4.5% and moderate HGF in 20.9% of infants. Each unit increase in head circumference z-score at birth was associated with increased odds for severe and moderate HGF (odds ratios [OR] 5.29, 95% confidence intervals [CI] 4.67-6.00, and OR 2.38, 95% CI 2.23-2.54 respectively). Both severe and moderate HGF were associated with respiratory distress syndrome (OR 2.03, 95% CI 1.58-2.62, and OR 1.66, 95% CI 1.48-1.85 respectively); bronchopulmonary dysplasia (OR 3.38, 95% CI 2.33-4.91, and OR 1.87, 95% CI 1.52-2.30 respectively); necrotizing enterocolitis (OR 2.89, 95% CI 2.04-4.09, and OR 1.72, 95% CI 1.38-2.16 respectively), and sepsis (OR 2.06, 95% CI 1.69-2.50, and OR 1.38, 95% CI 1.24-1.53 respectively). INTERPRETATION Major neonatal morbidities were associated with HGF in VLBW infants born preterm. Identification of whether this is a direct effect of these morbidities or mediated through nutritional or growth factors may enable interventions to improve postnatal head growth of infants born preterm.

Abstract
BACKGROUND No information is available regarding the association between low plasma glucose levels and cause-specific and all-cause mortality in patients with coronary artery disease (CAD). We aimed to investigate the relationship between hypoglycaemia and all-cause, cardiovascular and cancer mortality in a large population of patients with CAD. DESIGN Patients were recruited from the BIP (Bezafibrate Infarction Prevention) registry, a secondary prevention prospective multicentre randomized, placebo-controlled, double-blind trial aimed to assess the efficacy of bezafibrate in reduction of coronary events. METHODS The study included 14,670 CAD patients aged 45-74, divided into six groups: (1) hypoglycaemic (up to 69 mg/dl); (2) low normal (70-79 mg/dl); (3) euglycaemic (80-109 mg/dl); (4) impaired fasting glucose (IFG) (110-125 mg/dl); (5) borderline diabetics (126-139 mg/dl); (6) diabetics (> or 140 mg/dl). RESULTS Patients comprised 131 with hypoglycaemia (0.9%), 731 with low normal glucose (5%), 9308 euglycaemic (63.4%), 1577 with IFG (10.7%), 617 borderline diabetics (4.2%) and 2306 diabetics (15.7%). Over a mean 8-year follow-up, crude all-cause mortality was higher in both diabetic (31.8%) and hypoglycaemic groups (25.2%) as compared with euglycaemics (14.9%; P<0.0001); CAD mortality was higher in diabetic and borderline groups (17.8 and 13.3%, respectively, versus 7.9% in euglycaemics; P<0.0001). The highest prevalence of cancer mortality was documented in the hypoglycaemic group (6.1 versus 2.9% in euglycaemics; P<0.02). Actuarial survival curves showed the lowest mortality in euglycaemic and low normal groups; the highest was seen in diabetic and hypoglycaemic patients. Intermediate values were found in borderline and IFG patients. After adjustment for variables, a significantly higher mortality rate was seen in hypoglycaemics when compared with euglycaemics (P<0.0001). Hypoglycaemia was identified as a predictor of increased all-cause and cancer mortality with a hazard ratio (HR) of 1.84 [95% confidence interval (CI) 1.29-2.61] and 2.26 (95% CI 1.12-4.57), respectively, but not of increased CAD mortality, with HR 1.30 (95% CI 0.73-2.29). CONCLUSIONS Over a mean 8-year follow-up, hypoglycaemia emerges as a marker for substantially increased all-cause and cancer mortality among patients with CAD presenting with low fasting glucose levels.

Abstract
The study aimed to examine differences in medication use among midlife women from different cultural origins and to identify socio-demographic, health, and lifestyle characteristics associated with prescribed and non-prescribed medication use. Face-to-face interviews with women aged 45-64 years were conducted during 2004-2006 within three population groups: long-term Jewish residents (LTJR), immigrants from the former Soviet Union after 1989, and Arab women. The survey instrument included current use of medications and way of purchasing (with/without prescription). The level of prescribed and non-prescribed medication use was categorized as taking none, taking 1-2, and taking 3 or more medications. The rates of medication use were 59.5% for prescribed medication and 47% for non-prescribed medications. Differences between the minority groups and LTJR were observed mainly for cardiovascular, vitamins, supplements, and hormonal medications. The analyses showed significantly lower use of prescribed medications among immigrants and of non-prescribed medications among Arab women after taking into account health and socioeconomic indicators. Increased use of prescribed and non-prescribed medications was associated with worse health status and older age. Education was associated with increased use of non-prescribed medications. The disparities in pharmaceutical care may be linked to barriers in access to health care and to cultural preferences among minorities.

Abstract
OBJECTIVE In obese children, bone age (BA) tends to significantly exceed chronological age (CA). In vitro studies in mice suggest that insulin may directly modulate skeletal growth. We investigated whether there is an association between fasting insulin and BA maturation in obese children. METHODS The study cohort comprised 74 overweight and obese children ages 4 to 13 years. BA divided by CA was used as an index for bone advancement. Participants were classified into tertiles based on their BA:CA ratio. Advanced BA maturation was defined as the third tertile, with BA:CA > 1.21. Components of the metabolic syndrome, including fasting insulin, fasting glucose, triglycerides, and high-density lipoprotein (HDL) levels, were measured. RESULTS Children with advanced BA were significantly younger, had a higher body mass index (BMI)-Z score (BMI-Z), and were taller than children with bone advancement in the lower tertiles. Females had a 4.7-fold increased risk for advanced BA compared with males (95% confidence interval [CI], 1.29-17.1; P = .02). Children with a BMI-Z ≥ 1.96 and fasting insulin ≤ 30 μU/L had a 3.6-fold increased risk of advanced BA (95% CI, 1.00-12.8; P = 0.05). Moreover, hyperinsulinemia (fasting insulin > 30 μU/L) was associated with a 6.8-fold increased risk for advanced BA, independent of the degree of obesity (95% CI, 1.45-32.1; P = .01). CONCLUSION Marked hyperinsulinemia is associated with advanced BA in obese children. Insulin appears to modulate skeletal growth in humans.

Abstract
Congenital general anosmia (CGA) is a neurological disorder entailing a complete innate inability to sense odors. While the mechanisms underlying vertebrate olfaction have been studied in detail, there are still gaps in our understanding of the molecular genetic basis of innate olfactory disorders. Applying whole-exome sequencing to a family multiply affected with CGA, we identified three members with a rare X-linked missense mutation in the TENM1 (teneurin 1) gene (ENST00000422452:c.C4829T). In Drosophila melanogaster, TENM1 functions in synaptic-partner-matching between axons of olfactory sensory neurons and target projection neurons and is involved in synapse organization in the olfactory system. We used CRISPR-Cas9 system to generate a Tenm1 disrupted mouse model. Tenm1(-/-) and point-mutated Tenm1(A) (/A) adult mice were shown to have an altered ability to locate a buried food pellet. Tenm1(A) (/A) mice also displayed an altered ability to sense aversive odors. Results of our study, that describes a new Tenm1 mouse, agree with the hypothesis that TENM1 has a role in olfaction. However, additional studies should be done in larger CGA cohorts, to provide statistical evidence that loss-of-function mutations in TENM1 can solely cause the disease in our and other CGA cases.

Abstract
BACKGROUND Emerging adulthood is a challenging period for diabetes management. Our aim was to determine whether a dedicated transition clinic for emerging adults with type 1 diabetes can improve glycemic control and visit attendance. METHODS An observational study of 53 emerging adults (30 males) treated during 2010-2014 in a newly established transition clinic. The clinic was operated jointly by pediatric and adult endocrinologists and included a transition coordinator. Data collected included the source of referral, HbA1c levels, frequency of visit attendance, and acute complications. For 27 patients who had attended the pediatric clinic at the same medical center, data from up to 2 years preceding the transition were also collected. Patients filled the Diabetes Quality of Life-Youth questionnaire at the transition and 1 year later. RESULTS Mean ± SD age at the transfer to the transition clinic was 22.1 ± 2.7 years; mean disease duration was 8.4 ± 5.0 years. Follow-up duration at the transition clinic was 1.2 ± 1.1 years. Mean HbA1c levels decreased from 67 mmol/mol (95 % CI 63-72) [8.3 % (95 % CI 7.9-8.7)] at transfer to 57 mmol/mol (95 % CI 52-63) [7.4 % (95 % CI 6.9-7.9)] after 1 year (p < 0.001). Thirty-six patients (68 %) attended three or more visits during their first year in the transition clinic. The impact of diabetes on quality of life, disease-related worries, and life satisfaction did not change significantly during 1-year attendance in the transition clinic. CONCLUSIONS A dedicated transition clinic for emerging adults, with tailored support according to the developmental needs of emerging adulthood, showed improved glycemic control and visit attendance.

Abstract
OBJECTIVE The current study aimed to evaluate the profile of women who are most likely to undergo caesarean delivery on maternal request (CDMR) and clarify their reasons for this decision. METHODS For this multicentre case-control study, data were collected from 429 women who underwent CDMR and 429 matched controls who delivered vaginally from June, 2008 through February, 2009. Participants were interviewed by telephone regarding sociodemographic variables, health and lifestyle. RESULTS CDMR predictors were as follows: increasing age (OR = 1.09/year; 95%CI: 1.05-1.14), family status (unmarried without a steady partner versus married - OR = 3.60; 95%CI: 1.08-11.97), decreasing level of religiosity (secular versus ultra-orthodox - OR = 11.82; 95%CI: 3.75-37.21), and never having engaged, or ceasing sports activity during pregnancy (OR = 1.79; 95%CI: 1.09-2.91 and 2.38; 95%CI: 1.28-4.43, respectively). Above average income reduced the probability of CDMR (OR = 0.56; 95%CI: 0.33-0.94). The most frequent reasons for choosing CDMR were concern for pain (21.9%), concern for their own or baby's health (20.4% and 16.5%, respectively) and emotional aspects (10.0%). CONCLUSIONS Older, unmarried and/or secular women had increased probability of CDMR. Addressing specific concerns regarding vaginal delivery may provide the basis for a patient-oriented intervention for preventing unnecessary surgery.

Abstract
OBJECTIVES To examine cultural differences in Weight status misperception (WSMP) and identify associations between weight perception and weight control efforts among overweight/obese midlife women in Israel. METHODS Data from the nationally representative Women's-Health-in-Midlife-National-Study were used. Participants included overweight (25 ≤ BMI < 30) and obese (BMI ≥ 30) midlife women (45-64 years) from three cultural groups: Long-Term Jewish Residents (LTJR), Immigrants from the former USSR, and Arabs. Interviews included measures of BMI, weight perception, lifestyle, and socio-demographics. RESULTS Most overweight/obese women (88 %) perceived their weight status correctly. No significant differences were found in overall WSMP rates across cultural groups. Overweight women of Arab origin were significantly more likely (p < 0.001) to perceive their weight as "about right" relative to LTJR and Immigrants. WSMP was associated with several unhealthy eating patterns [eating red meat (OR = 2.1, 95 % CI = 1.13-3.97), white bread (OR = 2.4, 95 % CI = 1.26-4.58)] and with more perceived barriers to exercising (OR = 1.8, 95 % CI = 1.00-3.42). CONCLUSIONS Health care providers are encouraged to pay attention to overweight/obese women who misperceive their weight status. These women are more likely to consume unhealthy foods and to be at higher risks of suffering from medical complications associated with obesity.

Abstract
The current investigation aimed to assess levels of knowledge about risk factors for heart disease among midlife Israeli women, and to evaluate the relationship of knowledge to personal risk factors and vulnerability to heart disease. Face-to-face interviews with women aged 45-64 years were conducted during 2004-2006 within three population groups: long-term Jewish residents (LTR), immigrants from the former Soviet Union, and Arab women. The survey instrument included six knowledge statements relating to: the risk after menopause, family history, elevated cholesterol level, diabetes, obesity, and warning signs of a heart attack. The findings showed wide disparities in knowledge by educational level and between immigrants and LTR, after taking into account personal risk factors and education. Personal risk factors were not significantly related to the knowledge items, except for personal history of cardiovascular disease, which was associated with knowledge about "warning signs of a heart attack" and "family history." Women who perceived themselves as more vulnerable to heart disease were more likely to identify several risk factors correctly. These findings stress the need to increase knowledge about heart disease, especially among less educated and minority women, and to emphasize the risk of patients' personal status by health providers.

Abstract
BACKGROUND We aimed to determine the prevalence of overweight and obesity among children, adolescents and young adults with type 1 diabetes mellitus (T1DM), and to assess the prevalence of the metabolic syndrome and its components. METHODS The study cohort comprised 326 (168 women) consecutive patients aged 5 to 30 years diagnosed with T1DM and followed up in the Juvenile Diabetes Clinic, Maccabi Health Care Services. Anthropometric measurements, blood pressure, presence of additional diseases, other medications, HbA1c , triglycerides and high density lipoprotein cholesterol levels were obtained. RESULTS The mean age in the study group was 18.5 ± 6.0 years, and the mean diabetes duration was 8.7 ± 5.0 years. Mean HbA1c level was 8.1 ± 1.3%. Nineteen per cent of the study population was overweight (85th > body mass index < 95th percentile) and 5.2% was obese (body mass index ≥ 95th percentile). Female patients aged 15 ≤ 18 and 18 ≤ 25 years were significantly overweight compared with healthy Israeli women in the same age groups, 33.3% versus 12.7% and 26.3% versus 7.8%, respectively, p < 0001. There were no obese female patients in the 15 ≤ 18 age group. Among the men in all age groups, there was no difference in the prevalence of overweight and obesity compared with healthy men in the general population. There was no difference in the age of onset, disease duration, HbA1c levels, treatment with anti-depressants and associated morbidities between the normal weight, overweight and obese groups. Obese patients had lower levels of HDL and increased prevalence of hypertension and metabolic syndrome. CONCLUSIONS Overweight but not obesity was more prevalent in women with T1DM. Metabolic syndrome and its components were more prevalent among overweight and obese individuals with T1DM than among normal weight individuals.

Abstract
BACKGROUND Over the last decade, there is growing evidence that exposure to air pollution may be associated with increased risk for congenital malformations. OBJECTIVES To evaluate the possible association between exposures to air pollution during pregnancy and congenital malformations among infants born following spontaneously conceived (SC) pregnancies and assisted reproductive technology (ART) pregnancies. METHODS This is an historical cohort study comprising 216,730 infants: 207,825 SC infants and 8905 ART conceived infants, during the periods 1997-2004. Air pollution data including sulfur dioxide (SO2), particulate matter <10 µm (PM10), nitrogen oxides (NOx) and ozone (O3) were obtained from air monitoring stations database for the study period. Using a geographic information system (GIS) and the Kriging procedure, exposure to air pollution during the first trimester and the entire pregnancy was assessed for each woman according to her residential location. Logistic regression models with generalized estimating equation (GEE) approach were used to evaluate the adjusted risk for congenital malformations. RESULTS In the study cohort increased concentrations of PM10 and NOx pollutants in the entire pregnancy were associated with slightly increased risk for congenital malformations: OR 1.06(95% CI, 1.01-1.11) for 10 µg/m(3) increase in PM10 and OR 1.03(95% CI, 1.01-1.04) for 10 ppb increase in NOx. Specific malformations were evident in the circulatory system (for PM10 and NOx exposure) and genital organs (for NOx exposure). SO2 and O3 pollutants were not significantly associated with increased risk for congenital malformations. In the ART group higher concentrations of SO2 and O3 in entire pregnancy were associated (although not significantly) with an increased risk for congenital malformations: OR 1.06(95% CI, 0.96-1.17) for 1 ppb increase in SO2 and OR 1.15(95% CI, 0.69-1.91) for 10 ppb increase in O3. CONCLUSIONS Exposure to higher levels of PM10 and NOx during pregnancy was associated with an increased risk for congenital malformations. Specific malformations were evident in the circulatory system and genital organs. Among ART pregnancies possible adverse association of SO2 and O3 exposure was also observed. Further studies are warranted, including more accurate exposure assessment and a larger sample size for ART pregnancies, in order to confirm these findings.

Abstract
Silica polymerization in a supersaturated aqueous solution of sodium silicate is a fundamental mineralization process with broad relevance for technical applications as well as for biological processes. To contribute to a better understanding of the mechanism underlying the polymerization of sodium silicate under ambient conditions, a combined multiangle static and dynamic light scattering study on the evolution of particle mass and size is applied for the first time in a time-resolving manner. The light scattering experiments are complemented by a time-resolved analysis of the decay of the concentration of monomeric silicate by means of the silicomolybdate method. Particle formation was investigated at a variable concentration of silicate at pH 7 and 8. The joint experiments revealed a loss of monomers, which is parallel to the formation of compact, spherical particles growing by a monomer-addition process. An increase in the silicate content of up to 750 ppm increased the extent of nucleation and at the same time decreased the lag time observed between the start of the reaction and the actual onset of the growth of particles. Once the silica content is considerably larger than 1000 ppm, the formation of particles is succeeded by particle-particle agglomeration leading to larger fractal-like particles. By the time agglomeration becomes noticeable with light scattering, the monomer concentration has already reached its equilibrium value. An increase in the pH to 8 again revealed particle formation via a monomer-addition process. However, the extent of nucleation was increased and particle-particle agglomeration was inhibited even at an initial silica content of 2000 ppm.

Abstract
Purpose To illustrate the distribution of Hemoglobin A1c (HbA1c) levels according to age and gender among children, adolescents and youth with type 1 diabetes (T1DM). Methods Consecutive HbA1c measurements of 349 patients, aged 2 to 30 years with T1DM were obtained from 1995 through 2010. Measurement from patients diagnosed with celiac disease (n = 20), eating disorders (n = 41) and hemoglobinopathy (n = 1) were excluded. The study sample comprised 4815 measurements of HbA1c from 287 patients. Regression percentiles of HbA1c were calculated as a function of age and gender by the quantile regression method using the SAS procedure QUANTREG. Results Crude percentiles of HbA1c as a function of age and gender, and the modeled curves produced using quantile regression showed good concordance. The curves show a decline in HbA1c levels from age 2 to 4 years at each percentile. Thereafter, there is a gradual increase during the prepubertal years with a peak at ages 12 to 14 years. HbA1c levels subsequently decline to the lowest values in the third decade. Curves of females and males followed closely, with females having HbA1c levels about 0.1% (1.1 mmol/mol) higher in the 25th 50th and 75th percentiles. Conclusion We constructed age-specific distribution curves for HbA1c levels for patients with T1DM. These percentiles may be used to demonstrate the individual patient's measurements longitudinally compared with age-matched patients.

Abstract
BACKGROUND Overt neonatal Graves' disease is rare, but may be severe, even life threatening, with deleterious effects on neural development. The main objective of this study was to describe the course of thyrotropin (TSH) and free thyroxin (fT4) levels, as well as postnatal weight gain in relation to fT4 levels, in neonates born to women with Graves' disease without overt neonatal thyrotoxicosis. Such information is important to deduce the optimal schedule for evaluation. METHODS We conducted a retrospective chart review of neonates born to mothers with Graves' disease between January 2007 and December 2012. The records were reviewed for sex, gestational age, birth weight, maternal treatment during pregnancy, and maternal thyroid stimulating immunoglobulin (TSI) level. For each visit in the clinic, the data included growth parameters, presence of symptoms suspected for hyperthyroidism, blood test results (levels of TSH, fT4, and TSI), and treatment. RESULTS Ninety-six neonates were included in the study (49 males), with a total of 320 measurements of thyroid function tests (TSH and fT4). Four neonates (4%) had overt neonatal Graves' disease; one of them along with nine others were born preterm. In 77 (92.9%) of the remaining 83 neonates (the subclinical group), fT4 levels were above the 95th percentile on day 5. All had normal fT4 on day 15. A negative association was found between fT4 and weight gain during the first two weeks. CONCLUSIONS In this cohort, most neonates born to mothers with Graves' disease had a subclinical course with abnormal fT4 levels that peaked at day 5. After day 14, all measurements of fT4 returned to the normal range, although measurements of TSH remained suppressed for up to three months. Elevated fT4 was associated with poor weight gain.

Abstract
AIM To assess whether the postnatal growth of preterm very-low-birthweight (VLBW) infants, as determined by measures of postnatal growth failure (PNGF), improved during the period 1995-2010 and to evaluate postnatal growth by gestational age (GA) and intrauterine growth groups. METHODS The study was based on the Israel national VLBW infant database and comprised 13 531 VLBW infants of 24-32 weeks' GA, discharged at a postmenstrual age of ≤40 weeks. Z-scores were determined for weight at birth and discharge. Severe and mild PNGF was defined as a decrease >2 and 1-2 z-scores, respectively. Three time periods were considered: 1995-2000, 2001-2005 and 2006-2010. Multinomial logistic regression was used to assess the independent effect of time period on PNGF. RESULTS Severe PNGF decreased from 11.7% in 1995-2000 to 7.2% in 2001-2005 and 5.2% in 2006-2010. Infants born in 2006-2010 had sixfold lower odds for severe PNGF than babies born in 1995-2000 (adjusted odds ratio 0.17, 95% confidence interval 0.14-0.21) and <twofold lower odds for mild PNGF (adjusted odds ratio 0.42, 95% confidence interval 0.39-0.48). CONCLUSION We demonstrated a marked decline in PNGF among preterm VLBW infants from 1995-2000 to 2006-2010. This decline was even present in extremely premature infants.

Abstract
OBJECTIVE Intentional insulin omission is a unique inappropriate compensatory behavior that occurs in patients with type 1 diabetes mellitus, mostly in females, who omit or restrict their required insulin doses in order to lose weight. Diagnosis of this underlying disorder is difficult. We aimed to use clinical and laboratory criteria to create an algorithm to assist in the detection of intentional insulin omission. METHOD The distribution of HbA1c levels from 287 (181 females) patients with type 1 diabetes were used as reference. Data from 26 patients with type 1 diabetes and intentional insulin omission were analysed. The Weka (Waikato Environment for Knowledge Analysis) machine learning software, decision tree classifier with 10-fold cross validation was used to developed prediction models. Model performance was assessed by cross-validation in a further 43 patients. RESULTS Adolescents with intentional insulin omission were discriminated by: female sex, HbA1c>9.2%, more than 20% of HbA1c measurements above the 90th percentile, the mean of 3 highest delta HbA1c z-scores>1.28, current age and age at diagnosis. The models developed showed good discrimination (sensitivity and specificity 0.88 and 0.74, respectively). The external test dataset revealed good performance of the model with a sensitivity and specificity of 1.00 and 0.97, respectively. DISCUSSION Using data mining methods we developed a clinical prediction model to determine an individual's probability of intentionally omitting insulin. This model provides a decision support system for the detection of intentional insulin omission for weight loss in adolescent females with type 1 diabetes mellitus.

Abstract
Background During several months in 2009–2010, the Israeli population was asked to take part in two preparedness programs: Acquisition of gas masks against a potential chemical-warfare attack, and vaccination against the A/H1N1 influenza pandemics. Compliance with the first request was moderate and did not attract much attention, whereas compliance with the second request was very low and was accompanied by significant controversy. The aims of this study are to compare the public’s attitudes towards these two preparedness campaigns, and to explore the roles of trust, reasoned assessment, and reflexive reactions in the public’s response to governmental preparedness policies. Methods The comparative analysis was based on a telephone survey of 2,018 respondents representing a cross-section of the adult Israeli population. Univariate analysis to describe associations of public response and attitude was performed by Chi-square tests. Findings A set of queries related to actual compliance, trust in credibility of authorities, personal opinions, reasons for non-compliance, and attitudes towards uncertainties was used to characterize the response to mask-acquisition and vaccination. In the case of mask-acquisition, the dominant response profile was of trusting compliance based on non-conditional belief in the need to adhere to the recommendation (35.6% of respondents). In the case of vaccination, the dominant response profile was of trusting non-compliance based on a reflective belief in the need for adherence (34.8% of respondents). Among the variables examined in the study, passivity was found to be the major reason for non-compliance with mask-acquisition, whereas reasoned assessment of risk played a major role in non-compliance with vaccination. Realization of the complexity in dealing with uncertainty related to developing epidemics and to newly-developed vaccines was identified in the public’s response to the H1N1 vaccination campaign. Conclusions The newly identified profile of “trusting-reflective-non-complier” individuals should be of concern to policy makers. The public is not accepting governmental recommendations in an unconditional manner. This is not driven by lack of trust in authorities, but rather by the perception of the responsibility of individuals in confronting forthcoming risks. Nevertheless, under certain conditions the public may respond in a non-reflective way and delegate this responsibly to authorities in an uncontested manner. This leaves the policy makers with the complex challenge of interacting with a passive non-involved public or alternatively with an opinionated, reflexive public.

Abstract
AIMS To identify clinical characteristics and co-morbidity rates of children diagnosed with Type 1 diabetes mellitus at younger than 6 years of age. METHODS Data were obtained from a retrospective chart review of 103 patients diagnosed with Type 1 diabetes at younger than 6 years (study group) and 220 patients at older than 6 years (comparison group). Measures of glycaemic control and occurrence of co-morbidities (coeliac disease, autoimmune thyroid disease, hypertension, nephropathy and retinopathy) were compared. RESULTS The mean follow-up period was more than 8 years. For the study group, mean HbA(1c) levels ranged from 64 mmol/mol to 66 mmol/mol (8.0-8.2%) until age 10 years, and then rose to 73 mmol/mol (8.8%). The HbA(1c) levels were higher in the study than in the comparison group for comparable ages (P = 0.003). After adjustment for duration of diabetes this difference was not significant. The overall rate of severe hypoglycaemic events was greater in the study group than in the comparison group (P = 0.03). Kaplan-Meier diagnosis rates of celiac disease, 10 years after Type 1 diabetes diagnosis, were 14.4% and 4.2% in the study and comparison groups, respectively (P log-rank = 0.03). There were no differences in rates of autoimmune thyroid disease, hypertension, nephropathy or retinopathy. CONCLUSIONS Children diagnosed with Type 1 diabetes before the age of 6 years were in greater risk of developing celiac disease, compared with children diagnosed after the age of 6 years. For children diagnosed with Type 1 diabetes aged under 6 years, good metabolic control was achievable until age 10 years, after which it deteriorated. Higher HbA(1c) levels observed in children diagnosed before the age of 6 years were associated with longer duration of disease.

Abstract
The attitude of the general public to vaccination was evaluated through a survey conducted on a representative sample of the Israeli population (n = 2,018), in which interviewees were requested to express their standpoints regarding five different vaccination programs. These included: pandemic influenza vaccination, seasonal influenza vaccination, travel vaccines, Human Papilloma Virus vaccine and childhood vaccinations. Analysis of the responses reveal three major attitude traits: a) acceptance, characterized by the opinion that targets should be vaccinated; b) individualism, characterized by the opinion that vaccination should be left to personal choice; and c) differentiation, characterized by the tendency to express different attitudes when addressing different vaccination programs. Interestingly, direct opposition to vaccination was found to be a minor attitude trait in this survey. Groups within the population could be defined according to their tendency to assume these different attitudes as Acceptors, Judicious-acceptors, Differentiators, Soft-individualists, and Hard-individualists. These groups expressed different standpoints on all five vaccination programs as well as on other health recommendations, such as screening for early detection of cancer. Attitude traits could be also correlated, to a certain extent, with actual compliance with vaccination programs. Interestingly, attitudes to vaccination were not correlated with social profiles related to income or education, although younger individuals exhibited higher degrees of individualism and differentiation. Taken together, all this is in accordance with the current social settings, underlining the individual's tendency for critical evaluation and self-stirring. This should be taken into consideration by health authorities involved in vaccination programs.

Abstract
AIMS This study aimed to examine differences in symptom clusters among women in midlife from different cultural origins and to identify sociodemographic, lifestyle, and health characteristics that could account for the differences between the cultural groups in symptom reporting. METHODS Israeli women aged 45-64 were randomly selected according to age and population strata of three groups: long-term Jewish residents (LTR), Jewish immigrants from the former Soviet Union, and Arab women (mostly Israeli-born). Interviews were conducted with 540 LTR, 151 immigrants, and 123 Arab women. The survey instrument included the occurrence and rating of how bothersome to everyday function were 16 symptoms. Three outcome variables included hot flashes and two scales for mental and somatic symptoms extracted from exploratory factor analysis. RESULTS Multivariate logistic regressions showed that immigrants and Arab women (compared to LTR) had a significantly lower risk of reporting hot flashes and mental and somatic symptoms. Menopausal status was related only to hot flashes. Low education and depression were associated with the three symptom scales, whereas nonhealthy lifestyle was related only to somatic symptoms. CONCLUSIONS Our main finding is that cultural group is an independent predictor of each of the three menopausal symptom scales. A possible explanation for the lower reporting of symptoms among Arab and immigrant groups is that they differ from the LTR in level of acculturation and attitudes toward menopause. These findings support the proposition of a cultural factor in menopausal symptomatology that needs to be addressed by clinicians caring for women at midlife.

Abstract
A detailed in situ scattering study has been carried out on the formation of amorphous calcium carbonate (ACC) particles modulated by the presence of small amounts of sodium polyacrylate chains. The work is aiming at an insight into the modulation of ACC formation by means of two polyacrylate samples differing in their molecular weight by a factor of 50. The ACC formation process was initiated by an in situ generation of CO(3)(2-) ions via hydrolysis of 10 mM dimethylcarbonate in the presence of 10 mM CaCl(2). Analysis of the formation process by means of time-resolved small-angle X-ray and light scattering in the absence of any additives provided evidence for a monomer addition mechanism for the growth of ACC particles. ACC formation under these conditions sets in after a lag-period of some 350 s. In the presence of sodium polyacrylate chains, calcium polyacrylate aggregates are formed during the lag-period, succeeded by a modulated ACC growth in a second step. The presence of anionic polyacrylate chains changed the shape of the growing particles toward loose and less homogeneous entities. In the case of low amounts (1.5-7.5 mg/L) of the long chain additive with 97 kDa, the size of the aggregates is comparable to the size of the successively formed hybrid particles. No variation of the lag-period has been observed in this case. Use of the short chain additive with 2 kDa enabled increase of the additive concentration up to 100 mg/L and resulted in a significant increase of the lag-period. This fact, together with the finding that the resulting hybrid particles remained stable in the latter case, identified short chain sodium polyacrylates as more efficient modulators than long chain polyacrylates.

Abstract
OBJECTIVE We hypothesized that maternal diabetes mellitus (DM) increases the risk for mortality, respiratory distress syndrome (RDS), and major complications of prematurity. METHODS Analysis of prospectively collected (1995-2007) Israel National Very Low Birth Weight Infant Database. Maternal DM was recorded as pregestational or gestational. Multivariable logistic regression analysis was used to assess the independent effect of maternal DM status on infant mortality, RDS, and other complications of prematurity. RESULTS Infants of mothers with pregestational (n = 120) and gestational (n = 825) DM were similar, and their data were pooled for analyses. Mothers with DM were more likely to have received a complete course of prenatal steroids than control mothers. Infants of diabetic mothers (IDM) had a slightly higher gestational age and birthweight than non-IDM's. Distribution of birthweight percentiles and the mean birthweight z scores were similar. Apgar scores were statistically higher in the IDM group. There were no significant differences between the 2 groups in terms of delivery room mortality, RDS, and other major complications of prematurity. Total mortality and bronchopulmonary dysplasia rates were significantly higher in the nondiabetic group. The adjusted odds ratios for mortality, RDS, bronchopulmonary dysplasia, intraventricular hemorrhage, periventricular leukomalacia, retinopathy of prematurity, necrotizing enterocolitis, and patent ductus arteriosus were not significantly increased in the IDM group. CONCLUSIONS With modern management and adequate prenatal care, IDM born very low birthweight do not seem to be at an excess risk of developing RDS or other major complications of prematurity compared with non-IDM.
