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.

Background: Depression is a leading cause of morbidity, disability and health care utilization. It is commonly encountered in primary care settings yet is often missed or suboptimally managed.

Objective: To summarize studies conducted in Israel on the prevalence of depression in primary care settings, its correlates, and predictors of treatment and outcome, and to discuss their implications for clinical practice and public health policy.

Methods: An electronic search was conducted using the MEDLINE and PsychINFO databases. The inclusion criteria were original studies that assessed aspects of depression in a population aged 18 or older, were conducted in primary care settings in Israel, and with sufficient detailed description of depression-related measures, study sample and outcome measures. Twelve articles reporting results from 7 studies met these criteria.

Results: The prevalence of current depression in primary care varied considerably across studies: 1.6–5.9% for major depression, 1.1–5.4% for minor depression, 14.3–24% for depressive symptoms. Depression was consistently related to female gender and few years of education, and was associated with disability, decreased quality of life, and increased health-related expenditure. Many cases of depression were undiagnosed and most patients had persistent depression or achieved only partial remission.

Conclusions: Depression represents a serious challenge for the primary health care system in Israel. Greater efforts should be focused on screening and treating depression in primary care. However, the studies reviewed here used different methodologies and assessed different aspects of depression, and, therefore, should be generalized cautiously. Systematic research on the prevalence, correlates and management of depression in primary care, with emphasis on collaborative care models, is strongly needed to inform research, clinicians and health care policy makers.

Background: Persistent creatine kinase elevation is occasionally encountered in subjects without any clinical manifestation of a neuromuscular disorder or any condition known to be associated with increased serum CK[1] levels. It is still unresolved whether extensive investigations and specifically a muscle biopsy should be performed in clinically normal individuals with elevated CK levels.

Objective: To study the muscle pathology of patients with asymptomatic or minimally symptomatic hyperCKemia.

Methods: The clinical and laboratory data of patients with persistent hyperCKemia and normal neurologic examination were reviewed and their muscle biopsies evaluated.

Results: The study group included 40 patients aged 7–67 years; the male to female ratio was 3:1. Nineteen patients were completely asymptomatic, 20 had mild non-specific myalgia, and 1 had muscle cramps. Electromyography was performed in 27 patients and showed myopathic changes in 7 (26%). Abnormal muscle biopsy findings (e.g., increased variation in fiber size, increased number of central nuclei and occasional degenerating fibers) were detected in 22 of the 40 patients (55%). No fat or glycogen accumulation was detected. Immunohistochemistry demonstrated abnormal dystrophin staining in 3 patients (8%), resembling the pathologic changes of Becker muscular dystrophy. No abnormal findings were detected on immunohistochemical staining for merosin, dysferlin, caveolin 3, or alpha and gamma sarcoglycans. The EMG[2] findings did not correlate with the pathologic findings.

Conclusions: Abnormal muscle biopsies were found in 55% of patients with asymptomatic or minimally symptomatic hyperCKemia. Specific diagnosis of muscular dystrophy, however, was possible in only 8% of the patients.

Objectives: To examine whether hostility, anxiety and autobiographical memory (a correlate of depression) are associated with IIH[1].

Methods: Using a case-control cross sectional design, 20 patients with IIH were compared with 9 healthy controls of similar age, weight and height, and 11 headache controls. Patients were assessed for hostility and anxiety. The Autobiographical Memory Test was used to assess episodic memories.

Results: The IIH group reported significantly more anxiety and more general episodic memories than the healthy controls, but not the headache control group. The headache control patients reported more general memories than did the healthy controls.

Conclusions: Patients with headaches, whether of general origin or related to IIH, have a poor psychosocial profile. While the study design does not permit any conclusions regarding causality, our results support the need to consider psychological factors in evaluating and treating IIH and headache patients.

Background: A major psychological sequel of terrorist attacks is post-traumatic stress disorder. The relation between certain psychological factors specific to terrorist attacks (e.g., perceived control attributed to oneself/to the military, anticipated duration of terrorism) and PTSD[1] symptoms have not been examined.

Objective: To examine the prevalence, correlates and moderators of PTSD-like symptoms following terrorist attacks in Israel.

Methods: Soon after a long wave of terrorist attacks in Israel in 2002, a convenience sample of 149 Israelis from five cities was assessed for terrorist attack exposure, perceived control, control attributed to the government/military, anticipated duration of the terrorism wave (predictability), and frequency of listening to the news. PTSD-like symptoms were assessed with a brief self-report scale.

Results: We found that 15.4% of the sample was directly exposed to a terrorist attack and 36.5% knew someone close who had been exposed to an attack. “Clinically significant” PTSD-like symptoms were reported by 10.1% of the sample. Correlates of PTSD-like symptoms were: perceived control in men, government control, and education in women (all inversely correlated to PTSD symptoms), and news-listening frequency in women (positively correlated to PTSD symptoms). PTSD-like symptoms were attenuated by the ability to predict the duration of the terrorism wave only in citizens exposed to an attack, and by perceived government control only among citizens listening infrequently to the news.

Conclusions: This study revealed that approximately 10% of Israelis in our sample had relatively frequent PTSD-like symptoms. Correlates of PTSD-like symptoms differed between men and women, and moderator effects were found. These findings reveal additional moderators that may have implications for treating PTSD following terrorist attacks.

Background: Previous reports on the behavior of procalcitonin blood levels in diverse clinical conditions suggest that it is part of the activation of cellular immunity and is another acute-phase reactant.

Objective: To compare procalcitonin with C-reactive protein, a well-known acute-phase reactant, in a series of acutely febrile pediatric patients and to review recent literature on procalcitonin.

Methods: Procalcitonin and CRP levels were evaluated in 38 blood samples of pediatric patients who were admitted to the Dana Children’s Hospital for evaluation of unexplained fever or for sepsis work-up.

Results: The parallelism between procalcitonin and CRP was found to be highly significant (P<0.01).

Conclusion: The rise of procalcitonin blood levels in febrile pediatric patients suggests that it is part of the acute-phase reaction, parallel with the CRP reaction.
