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.

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.

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.

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.

The PANI film was directly electrodeposited on the platinum wire surface in sulfuric acid solution using cyclic voltammetry (CV) technique. The applicability of this coating was assessed employing a laboratory-made SPME device and gas chromatography with mass spectrometry (GC-MS) for the extraction of some PAHs from the headspace of aqueous samples. Application of wider potential range in CV led to a PANI with more stability against the temperature. The homogeneity and the porous surface structure of the film were examined by the scanning electron microscopy (SEM). The study revealed that this polymer is a suitable SPME fiber coating for extracting the selected PAHs. Important parameters influencing the extraction process were optimized and an extraction time of 40 min at 40 degrees C gave maximum peak area, when the aqueous sample was added with NaCl (20%, w/v). The synthesis of the PANI can be carried out conveniently and in a reproducible manner while it is rather inexpensive and stable against most of organic solvents. The film thickness of PANI can be precisely controlled by the number of CV cycles. The resulting thickness was roughly 20 microm after 20 cycles. At the optimum conditions, the relative standard deviation (RSD) for a double distilled water spiked with selected PAHs at ppb level were 8.80-16.8% (n = 3) and detection limits for the studied compounds were between 0.1-6 pg mL(-1). The performance of PANI was, also, compared with a commercial solid coated-based SPME fiber, carbowax/divinylbenzene (CW/DVB), under similar experimental conditions.

Since soil is a poor thermal conductor, a suitable arrangement of undersoil pipes is required in order to achieve a somewhat uniformly elevated soil temperature. Two dimensional steady temperature profiles in soil resulting from a warm water pipe having a wall temperature of 37.8C were computed for several pipe configurations and surface heat transfer coefficients of 1.36 and 136 cal.sec-1.m-2C-1. Values of heat transfer on the order of 5 cal.sec-1.sec-1.m-1 can be obtained. Calculations indicate that in order to apply this technique for the utilization of significant portions of reject heat, the system must be viewed in terms of an agricultural power plant complex encompassing large quantities of land.

The aim of this study was to evaluate strength of the bond between porcelain laminate veneers and tooth surfaces etched with acid and laser, separately and together. The teeth studied comprised 60 incisors extracted for periodontal reasons. These were divided into four groups according to etching method: group 1, acid etching alone; group 2, acid etching followed by laser etching; group 3, laser etching followed by acid etching; group 4, laser etching alone. The teeth were etched with 37% phosphoric acid and a Er,Cr:YSGG laser system. In addition, 60 IPS Empress II cylindrical blocks 2 mm in height and 5 mm in diameter were also prepared for the etched tooth surface. These blocks were bonded to the teeth with dual cured resin cement and shear tests were then performed. After the shear tests, Scanning electron microscopy images of the tooth surfaces were obtained at a magnification of x3,800. Etching with acid alone yielded the highest mean value of bond shear strength (15.4+/-3.8 MPa), while laser etching followed by acid etching gave the lowest mean value (11.5+/-4.6 MPa). The mean values of the bond shear strength for acid etching followed by laser etching and laser etching alone were 13.8+/-3.9 MPa and 12.8+/-4.6 MPa, respectively. Statistical analysis revealed no significant differences between the groups. The results suggest that laser etching is easy to apply and less time-consuming. They further suggest that the order in which the acid and laser are applied in combined treatments is important.

According to the investigators of these studies, the results indicate a possible link between cancer and exposure to 60-Hz magnetic fields, because residential magnetic fields are correlated with wiring configurations. I propose an alternate hypothesis to explain the epidemiologic observations, namely, that ground return currents in plumbing service lines are associated with electric wiring configuration, and cause the release of corrosion products in tap water, ingestion of which constitutes a risk factor for cancer. To corroborate this hypothesis, three conditions must be satisfied: (1) the magnitude of the ground return currents in water pipes is related to wiring configuration, with higher currents generally found associated with homes classified in the high-exposure categories; (2) corrosion on the internal surface of water pipe is related to alternating currents flowing on the pipe, with higher currents associated with higher rates of corrosion; and (3) ingestion of water from pipes undergoing alternating-current-related corrosive processes increases the probability of developing cancer.

Fast-growing families showed greater plasticity in allocating biomass to shoots at high nitrogen supply and to roots at low nitrogen supply than slow-growing families. Compared with the slow-growing families, short-term net ammonium uptake rate measured with an ion selective electrode was significantly greater in fast-growing families at high ammonium supply, but not at low supply. Net nitrate uptake showed the same trend, but differences among families were not significant. Results indicate that differences in seedling growth rate are partly a result of physiological differences in net nitrogen uptake efficiency and nitrogen productivity.
