Objective Risk factor modification is key to preventing subsequent cardiac events after a heart attack. This study was designed to investigate the disparity between preventive guidelines and clinical practice among smoking patients. Methods The study was carried out in smokers admitted with myocardial infarction (MI). Atotal of 275 patients who had been regularly followed for over one year after MI were randomly selected and enrolled in this *** investigated changes in smoking behavior and the adherence rate to ACC/AHA Guidelines for secondary prevention in patients with coronary artery disease at the time of, and one year after, the index event. Results The study population consisted of 275 patients (97.1% males) with a mean age of 57.0 ±11.2 years. Achievement of target goals at one year was as follows: smoking cessation, 52.3%; blood pressure, 83.9%; HbA1c, 32.7%; lipid profile, 65.5%; and body mass index (BMI), 50.6%. Over one year, 80% of the patients attempted to quit smoking; 27% of them re-started smoking within one month after discharge while 65% succeeded in cessation of smoking. At one year, only 52% of the patients overall had stopped smoking. From the multivariate logistic analysis including smoking patterns and clinical characteristics, the severity of coronary artery disease was the only independent predictor for smoking cessation (Relative risk (RR): 1.230; P = 0.022). Conclusions Only a small percentage of MI patients adhere to guidelines for secondary prevention and a sizable proportion fail to stop smoking. These findings underscore the need for an effective patient education system.

To the Editor: Hailey-Hailey disease (HHD), first discovered by the brothers Howard and Hugh Hailey,[1]is a genodermatosis at intertriginous sites. Mutation of ATP2C1 on chromosome 3q21-2 coding a calciumdependent ATPase gives rise to calcium dysfunction within keratinocytes, resulting in acantholysis due to a signal transduction disorder.[2] It has been suggested that this gene mutation combined with irritation such as frequent friction, cold, and ultraviolet exposure leads to the development of HHD.[3]

Background In real practice, two or more antihypertensive drugs are needed to achieve target blood pressure. We investigated the comparative beneficial actions of combination therapy of renin-angiotensin system inhibitors (RASI), with calcium channel blockers (CCB) over CCB monotherapy on the development of new-onset diabetes mellitus (NODM) in Korean patients during four-year follow-up periods. Methods A total of 3208 consecutive hypertensive patients without a history of diabetes mellitus who had been prescribed CCB were retrospectively enrolled from January 2004 to December 2012. These patients were divided into the two groups according to the additional use of RASI (the RASI group, n = 1221 and the no RASI group, n = 1987). Primary endpoint was NODM, defined as a fasting blood glucose ≥ 126 mg/dL or hemoglobin A1c ≥ 6.5%. Secondary endpoint was major adverse cardiac events (MACE) defined as total death, myocardial infarction (MI) and percutaneous coronary intervention (PCI). Results After propensity score-matched (PSM) analysis, two propensity- matched groups (939 pairs, n = 1878, C-statistic = 0.743) were generated. The incidences of NODM (HR = 1.009, 95% CI: 0.700–1.452, P = 0.962), MACE (HR = 0.877, 95% CI: 0.544–1.413, P = 0.589), total death, MI, PCI were similar between the two groups after PSM during four years. Conclusions The use of RASI in addition to CCB showed comparable incidences of NODM and MACE compared to CCB monotherapy in non-diabetic hypertensive Korean patients during four-year follow-up period. However, large-scaled randomized controlled clinical trials will be required for a more definitive conclusion.

The effects of fixation drying conditions on fixation rates and chemical leachab ility were investigated with CCA-C treated red pine (Pinus koraiensis Sieb. )and southern pine specimens at a retention of 6 4 kg·m -3 , and under 11 post-treatment schedules ra ng ing from 50～70℃ and 5 different relative humidity conditions. These samples w e re monitored by expressing residual liquid and analyzing it for hexavatent chrom ium content. Samples were subjected to AWPA E11-97 (AWPA 1997) standard leachi n g tests after fixation. Generally, red pine fixed slightly faster than southern pine for most fixation conditions. High temperature, high humidity, fixation co nditions during the fixation/drying schedules resulted in faster fixation and lo wer leaching of chromium and arsenic elements compared to low humidity condition s. Copper leaching showed no significant difference under 11 fixation /drying co nditions for both species. All of the CCA components were leached significantly more in red pine than southern pine. Further work is needed to examine the effec ts of different fixation/drying conditions on leaching from full\|size samples a n d to optimize dry/wet bulb depression for fixation/drying of CCA treated lumber.
