Abstract
BACKGROUND: Other forms of tobacco use are increasing in prevalence, yet most tobacco control efforts are aimed at cigarettes. In light of this, it is important to identify individuals who are using both cigarettes and alternative tobacco products (ATPs). Most previous studies have used regression models. We conducted a traditional logistic regression model and a classification and regression tree (CART) model to illustrate and discuss the added advantages of using CART in the setting of identifying high-risk subgroups of ATP users among cigarettes smokers. METHODS: The data were collected from an online cross-sectional survey administered by Survey Sampling International between July 5, 2012 and August 15, 2012. Eligible participants self-identified as current smokers, African American, White, or Latino (of any race), were English-speaking, and were at least 25 years old. The study sample included 2,376 participants and was divided into independent training and validation samples for a hold out validation. Logistic regression and CART models were used to examine the important predictors of cigarettes + ATP users. RESULTS: The logistic regression model identified nine important factors: gender, age, race, nicotine dependence, buying cigarettes or borrowing, whether the price of cigarettes influences the brand purchased, whether the participants set limits on cigarettes per day, alcohol use scores, and discrimination frequencies. The C-index of the logistic regression model was 0.74, indicating good discriminatory capability. The model performed well in the validation cohort also with good discrimination (c-index = 0.73) and excellent calibration (R-square = 0.96 in the calibration regression). The parsimonious CART model identified gender, age, alcohol use score, race, and discrimination frequencies to be the most important factors. It also revealed interesting partial interactions. The c-index is 0.70 for the training sample and 0.69 for the validation sample. The misclassification rate was 0.342 for the training sample and 0.346 for the validation sample. The CART model was easier to interpret and discovered target populations that possess clinical significance. CONCLUSION: This study suggests that the non-parametric CART model is parsimonious, potentially easier to interpret, and provides additional information in identifying the subgroups at high risk of ATP use among cigarette smokers.

Abstract
Studies have reported that between 28 and 62% of pregnant teenagers smoke (Cornelius, Taylor, Geva, & Day, 1995; Trollestrup, Frost, & Starzyk, 1992). Because smoking is prevalent among pregnant teenagers, the purpose of this research is to assess nicotine dependence in this high-risk group. This study analyzed baseline data from a sample of pregnant teen smokers who had volunteered to participate in a smoking cessation study (N = 94). Nicotine dependence was measured by adapting the Fagerstrom Tolerance Questionnaire (FTQ; Prokhorov, Pallonen, Fava, Ding, & Niaura, 1996), and by a 6-item withdrawal symptom scale. The overall FTQ score found among pregnant adolescents was 3.10 (SD = 2.3) compared to the mean overall FTQ score among vocational-technical students of 4.27 (SD = 2.2) (Prokhorov et al., 1996). Duration of smoking in years was significantly correlated with the overall FTQ score (r = 0.43, p < .01). Quantity of smoking, as measured by average number of cigarettes smoked, significantly correlated with overall FTQ scores (r = 0.67, p < .01). Lighter smokers were more likely to have previously attempted to quit, however, among the quit attempters, those who smoked 10+ cigarettes per day reported greater severity of withdrawal symptoms than those who smoked less per day. Prenatal education and smoking cessation programs for pregnant teenagers, and pregnant women in general, need to consider that nicotine dependence is an important issue. Early pregnancy may be an opportune time to intervene among pregnant smokers; incentives may be necessary to attract those women who are the heaviest smokers, and possibly the most dependent on nicotine.; PIP: This study assessed nicotine dependence among pregnant adolescent smokers in order to enhance the efficacy of smoking-cessation programs. This study analyzed baseline data from a sample of 94 pregnant teen smokers who had volunteered to participate in a smoking cessation study. Nicotine dependence was measured by adapting Fagerstrom Tolerance Questionnaire (FTQ), and by a 6-item withdrawal symptom scale. The overall FTQ score found among pregnant adolescents was 3.10 (SD = 2.3) compared to the mean overall FTQ score among vocational-technical students of 4.27 (SD = 2.2).

However, among the attempters to quit, those who smoked 10+ cigarettes per day reported greater severity of withdrawal symptoms than those who smoked fewer per day. Prenatal education and smoking cessation programs for pregnant teenagers, and pregnant women in general, need to consider that nicotine dependence is an important issue. Early pregnancy may be an opportune time to intervene among pregnant smokers; incentives may be necessary to attract those women who are heaviest smokers, and possibly the most dependent on nicotine.

Abstract
BACKGROUND AND OBJECTIVE: Severe periodontal disease is prevalent among patients with schizophrenia and is caused by the side effect of their medication, poor dental hygiene and smoking. The objective of this study was to evaluate whether the rate of periodontal disease could be modulated by changing the salivary flow rate (SFR) because of the use of antipsychotic medications in patients with schizophrenia. METHODS: Group A (n=33) included patients who used medications that may cause xerostomia, or dry mouth and Group B (n=20) included patients who used medications that may cause sialorrhea, an excessive secretion of saliva. The participants' periodontal status was assessed using the plaque index (PI), assessing bleeding on probing (BoP), probing pocket depth (PPD) and clinical attachment levels (CAL). RESULTS: The mean of PI and BoP was significantly higher in Group A than in Group B (P0.05). CONCLUSIONS: The researcher concluded that there is a high risk of periodontal disease among patients with schizophrenia, and there is an even higher risk of periodontal disease induced by medication that increased SFR. Preventive dental protocol should be increased during the dental health care of this disadvantaged patient group.

Abstract
It has already been reported that wet ash turns into a strong alkali agent, which can cause full-thickness skin burns. A case is presented which has the particularity of sustained, self-inflicted contact with wet ash. The coal used was the self-igniting type normally used for burning scented weed or for smoking the hubbly bubbly or shisha pipe.

Abstract
INTRODUCTION: Right-to-left shunt across a persistent foramen ovale (PFO) has been associated with cutaneous, neurological and vestibular decompression illness (DCI). Percutaneous closure of a PFO has been used to reduce the risk of DCI. There are no randomised controlled trial data to support PFO closure for the prevention of decompression illness (DCI), so the need for audit data on the safety and ef fi cacy of this technique has been recognised by the National Institute of Health and Clinical Excellence in the UK. METHOD: Retrospective audit of all transcatheter PFO closures to reduce the risk of DCI performed by a single cardiologist with an interest in diving medicine. RESULTS: A total of 105 eligible divers undergoing 107 procedures was identi fi ed. There was a low rate of procedural complications; a rate lower than a recent randomised trial of PFO closure for stroke. Atrial fi brillation required treatment in two patients. One patient with a previously repaired mitral valve had a stroke that was thought to be unrelated to the PFO closure. Sixteen divers had minor post-procedure symptoms not requiring any treatment. Two divers required a second procedure because of residual shunt; both subsequently returned to unrestricted diving. Eighty-one of 95 divers in whom follow-up bubble contrast echocardiography was available returned to unrestricted diving. CONCLUSIONS: The PFO closure procedure appeared to be safe and was associated with the majority of divers being able to successfully return to unrestricted diving.

Abstract
AIM: Identification of the predominant lactic acid bacteria (LAB) involved in spontaneous fermentations of Almagro eggplants, and evaluation of the biodiversity by molecular typing. METHODS AND RESULTS: Almagro eggplant fermentations in three factories (A, B and C) enjoying Protected Designation of Origin (PDO) status were monitored by chemical and microbiological analysis of brines. LAB isolates from brines were identified by phenotypic analysis and by species-specific PCR reactions and typed by randomly amplified polymorphic DNA (RAPD)-PCR. All isolates from factories A and C belonged to the genus Lactobacillus (Lact.), whereas isolates from factory B belonged to Lactobacillus (50%), Leuconostoc (Ln.) (25%) and Lactococcus (Lc.) (25%); 1.9% of this microbiota was considered cosmopolitan. The genera Leuconostoc and Lactococcus and the species Lact. acidophilus and Lact. paracasei had never previously been reported in Almagro eggplant fermentations. CONCLUSION: Considerable differences in the composition of the lactic acid microbiota participating in the Almagro eggplant fermentations exist. Brine NaCl concentration has a notable influence both in number and in the species participating. SIGNIFICANCE AND IMPACT OF THE STUDY: The original aspect of this work consists of an ecological study of the LAB taking part in spontaneous Almagro eggplant fermentations from different factories. Participation of Leuconostoc and Lactococcus species and of Lact. acidophilus and Lact. paracasei, which had never before been described for this pickle, and the evidence that a lactic fermentation does not always take place, were the most relevant results.

Abstract
BACKGROUND: Low back pain is one of the most common conditions for which patients seek medical care. AIM: The aim of the study was to study the epidemiology of low back pain in primary care setting with emphasis on frequency, sociodemographic factors, and impact of low back pain on lifestyle habits. SUBJECTS AND METHODS: This is a cross-sectional study. A representative sample of 2742 patients was approached and 2180 subjects agreed to participate in this study (79.5%). The survey was conducted among primary health care visitors during the period from March to October 2012. The questionnaire collected the sociodemographic characteristics, lifestyle habits, and type of treatment taken for relief from recruited subjects. RESULTS: Of the subjects studied, 52.9% were males and 47.1% were females. The prevalence of low back pain in the study sample was 59.2%. Low back pain was more prevalent among women (67.7%) than among men (51.6%). The proportion of low back pain was highest in the age-group 45 to 55 years in both the genders (37.6% and 36.4%, respectively). Nearly half of the men (45.7%) and women (45.2%) with low back pain were overweight with a significant difference (P

Abstract
This study assessed differences in the indoor air quality and occupancy levels in seventeen bars due to a city-wide smoking ban that took effect on September 1, 2005 in Austin, Texas, USA. We measured the following in each venue before and after the smoking ban: mean number of occupants, mean number of lit cigarettes, temperature, relative humidity, room volume, and PM(2.5), CO, and CO(2) concentrations. Additionally, VOC measurements were conducted at three of the venues. There was not a statistically significant change in occupancy, but the best estimate PM(2.5) concentrations in the venues decreased 71-99%, a significant reduction in all venues, relative to the pre-ban levels; CO concentrations decreased significantly in all but one venue; and concentrations of VOCs known to be emitted from cigarettes decreased to below the detection limit for all but two common compounds. These results suggest that the smoking ban has effectively improved indoor air quality in Austin bars without an associated decrease in occupancy.
