Introduction: Acute myocardial infarction (AMI) is rare in “very young” patients and studies among Filipinos are scarce. The objective of this study is to determine the prevalence, clinical, echocardiographic and angiographic features, and outcome of this population. Methods: A retrospective study of patients aged 19 to 30 years old who were diagnosed with AMI at the Philippine Heart Center from 2012 to 2016 was done. Results: The prevalence of AMI in very young Filipino adults at our institution was 0.93% (11/1182). The mean age was 26.5±3.4 years with a male predominance (82%). Chest pain was the most common symptom (91%). More than half of the patients did not have heredofamilial diseases. Eight patients were smokers (72%). There was one case of illegal drug use (methamphetamine) (9%). There were only two cases of non-ST elevation myocardial infarction (NSTEMI) (18%). ST elevation myocardial infarction (STEMI) of the anterior wall was seen in four cases (36%), inferior wall in three cases (27%) and anterolateral wall in two cases (18%). Six patients (45%) had left anterior descending artery (LAD) involvement. Two patients (18%) had right coronary artery (RCA) involvement. Two patients (18%) had both LAD and RCA involvement. The youngest patient, a 19-year-old female with Takayasu arteritis, had three-vessel involvement. Five patients (45%) underwent percutaneous coronary involvement (PCI) of the LAD while two had PCI of the RCA (18%). All patients were discharged improved. Discussion: Acute myocardial infarction (AMI) in the young has not been extensively studied among Asians. Chest pain is the most common clinical presentation with STEMI being more frequent than NSTEMI in this age group. Male gender and smoking were the most common risk factors. Conclusion Early recognition and prompt management of AMI, particularly revascularization (if indicated), are of paramount importance to optimize outcomes.

Objective. This study determined the relationship between plasma adiponectin level and corrected QT interval (QTc) in smokers and non-smokers. Methodology.This cross-sectional analytical study was undertaken in 30 smokers and 30 non-smokers. Plasma adiponectin level was determined by enzyme-linked immunosorbent assay (ELISA). The QT interval was measured by routine 12-lead ECG with Lead II rhythm and QTc was calculated. Results. Mean plasma adiponectin level was significantly lower in smokers (27.89±15 μg/ml) than that of non-smokers (52.13±21.57μg/ml) (p<0.001). Mean QTc interval was significantly longer in smokers than that of non-smokers (415.37±29.9 versus 395.63±26.13 ms, p<0.01). Higher risk of low adiponectin level (odds ratio [OR],8.1; 95% confidence interval [CI],1.61-40.77) and QTc interval prolongation (OR,6; 95%CI,1.17-30.73) were observed in smokers. There was weak significant negative correlation between plasma adiponectin level and QTc interval in the study population (n=60, r=-0.407, p=0.001). Moreover, low plasma adiponectin level was significantly associated with prolonged QTc interval in the study population (n=60, Fisher's exact p value<0.05). Risk of QTc interval prolongation was 4.3 times higher in subjects with low plasma adiponectin level (OR,4.27; 95% CI,1.05-17.46). Conclusion. Smokers have greater risk for low plasma adiponectin level and prolonged QTc interval. There is a relationship between plasma adiponectin level and QTc interval.

OBJECTIVE: This study aimed to investigate the expression patterns and relationship of microtubule-associated protein 1 light chain 3 (LC3B) and mammalian target of rapamycin (mTOR) in oral leukoplakia (OLK) in smokers and never-smokers. This work also analyzed the relationship between smoking and the carcinogenic potential of OLK. METHODS: Immunohistochemistry was used to detect the expression of LC3B and mTOR in 120 patients with OLK. Clinical data from 120 smokers and never-smokers with OLK were analyzed. Subsequently, the relationships among LC3B and mTOR expression, clinical factors, and smoking were analyzed. RESULTS: Smoking and nonsmoking patients with OLK differed in terms of gender, age, lesion location, pathological typing, and carcinogenic situation. The positive rate of LC3B in never-smokers was higher than that in smokers. Whereas the positive rate of mTOR in smokers was higher than that in the corresponding never-smokers, and the differences were statistically significant (P<0.05). Smoking was positively correlated with the positive rate of mTOR (P<0.05), and had no significant correlation with LC3B expression. The positive rates of LC3B and mTOR were negatively correlated with the intensity of smoking (P<0.05). CONCLUSIONS The effect of smoking habits on OLK may be linked to the expression of proteins that are directly associated with autophagy.

OBJECTIVE: No consensus exists on the relative risk ( RR) of lung cancer (LC) attributable to active smoking in China. This study aimed to evaluate the unified RR of LC attributable to active smoking among the Chinese population. METHODS: A systematic literature search of seven databases was conducted to identify studies reporting active smoking among smokers versus nonsmokers in China. Primary articles on LC providing risk estimates with their 95% confidence intervals ( CIs) for "ever" "former" or "current" smokers from China were selected. Meta-analysis was used to estimate the pooled RR of active smoking. RESULTS: Forty-four unique studies were included. Compared with that of nonsmokers, the pooled RR (95% CI) for "ever" "former" and "current" smokers were 3.26 (2.79-3.82), 2.95 (1.71-5.08), and 5.16 (2.58-10.34) among men, 3.18 (2.78-3.63), 2.70 (2.08-3.51), and 4.27 (3.61-5.06) among women, and 2.71 (2.12-3.46), 2.66 (2.45-2.88), and 4.21 (3.25-5.45) in both sexes combined, respectively. CONCLUSION The RR of LC has remained relatively stable (range, 2-6) over the past four decades in China. Early quitting of smoking could reduce the RR to some extent; however, completely refraining from smoking is the best way to avoid its adverse effects.

ObjectiveTo investigate the clinical effects of the combined therapy of Compound Xuanju Capsules (CXJC) and traditional Chinese medicinal formula on infertility in male smokers.

METHODSA total of 176 male infertility patients were divided into a smoking and a non-smoking group and the former further divided into mild, moderate and heavy smokers according to the daily consumption of cigarettes and the length of smoking history. The patients were treated with CXJC combined with traditional Chinese medicinal formula for 3 four-week courses and the therapeutic results were evaluated by comparing the indicators of the traditional Chinese medicine (TCM) syndrome, routine semen parameters, sperm morphology, and sperm DNA fragmentation index (DFI) among different groups before and after treatment.

RESULTSThe baseline TCM syndrome scores were remarkably higher in the heavy smokers than in the non-smoking group (P < 0.05) but showed no statistically significant differences between the mild and moderate smokers (P > 0.05). The baseline percentage of sperm head defects and DFI were also markedly higher in the heavy and moderate smokers than in the non-smoking group (P < 0.05). Compared with the baseline, significant improvement was achieved after treatment in the TCM syndrome, routine semen parameters, sperm morphology and sperm DFI, especially in the heavy smokers in the percentages of grade a+b sperm (［17.12 ± 2.54］ vs ［30.15 ± 3.10］%, P < 0.05), morphologically normal sperm (［15.54 ± 1.98］ vs ［26.82 ± 3.52］%, P < 0.05), and head-defective sperm (［27.02 ± 2.14］ vs ［22.07 ± 1.52］%, P < 0.05).

CONCLUSIONSSperm quality is significantly decreased while the risk of infertility remarkably increased in moderate and heavy smokers. The combined therapy of CXJC and traditional Chinese medicinal formula can effectively improve semen quality, sperm morphology and sperm DFI in male smokers with infertility, though more evidence is to be collected from further studies.

Objective: To describe the relapse status of smokers aged ≥15 years in China, and investigate the main factors influencing their relapse behavior. Methods: The data of this study cames from the 2018 China Adult Tobacco Survey, covering 400 committees or villages in 200 districts or counties in 31 provinces (autonomous regions and municipalities) of China. The relevant data of smoking and relapsing in residents aged ≥15 years were collected by face-to-face interview. Software SAS 9.4 was used to clean and analyze the data, and logistic regression model was used to analyze the influencing factors for relapse rate. Results: A total of 19 376 questionnaires were completed, with a response rate of 91.50%. In 2018, 66.05% of smokers aged ≥15 years in China had smoking relapse, in whom 66.59% were males and 55.79% were females. In all age groups, the age group 15-24 years had the highest smoking relapse rate (82.63%). Multivariate analysis showed that the younger age 15-24 years (OR=4.618,95%CI:1.981-10.763), e-cigarette use (OR=9.782,95%CI:3.139-30.490), and tobacco advertising, promotion and sponsorship in the past 30 days (OR=1.710,95%CI:1.291-2.265) were associated with higher smoking relapse rate. Compared with people who were allowed smoking at home or those without smoking limit, the smoking relapse rate in people who were not allowed to smoke at home (OR=0.562, 95%CI: 0.439-0.719) or those with smoking limit (OR=0.487, 95%CI: 0.366-0.647) was lower. Conclusion: The smoking relapse rate in Chinese smokers is high, especially in young people. It is suggested to conduct targeted intervention based on the results of this study to reduce the smoking relapse rate and help achieve the smoking control goal in Healthy China 2030.

Objective: To understand the prevalence and influencing factors of tobacco dependence among the population aged 15-69 in Tianjin to provide the basis for formulating targeted smoking control intervention policies and carrying out scientific smoking cessation intervention services. Methods: The data of this study comes from the 2018 Tianjin residents' health literacy monitoring survey. Probability-proportional-to-size sampling is adopted for sampling. SPSS 26.0 software was used for data cleaning and statistical analysis, and χ² test and binary logistic regression were used to analyze the influencing factors. Results: A total of 14 641 subjects aged 15-69 were included in this study. After standardized, with a smoking rate of 25.5%, including 45.5% for men and 5.2% for women. Among the population aged 15-69, the prevalence of tobacco dependence was 10.7%; among current smokers, the prevalence rate of tobacco dependence is 40.1%, of which the prevalence rate of male tobacco dependence is 40.0%, and the prevalence rate of female tobacco dependence is 40.6%. According to multivariate logistic regression analysis, people who live in rural areas, have an education level of primary school or below, smoke every day, smoke the first cigarette ≤15 years old, smoke ≥21 cigarettes per day, and smoke for more than 20 packet years, people who report poor physical health are more likely to suffer from tobacco dependence (all P<0.05); age and smoking age did not affect the possibility of tobacco dependence (all P>0.05). Among current smokers, there was no significant difference in their willingness to quit smoking whether they had tobacco dependence (P>0.05). The proportion of people with tobacco dependence who have tried to quit smoking and failed is higher (P<0.001). Conclusions: The prevalence of tobacco dependence among smokers aged 15-69 in Tianjin is high, and the demand for quitting smoking is great. Therefore, smoking cessation publicity should be carried out for key groups, and smoking cessation intervention work in Tianjin should be continuously promoted.

BACKGROUND: Coronary Artery Disease (CAD) is closely associated with several major risk factors including many that can be modified or eliminated. Hypertension, diabetes mellitus, dyslipidemia, smoking and obesity are among these. Early identification of these risk factors gives the physician opportunities for primary and secondary prevention of CAD.
OBJECTIVE: To assess the practice of physicians with regards identification and management of risk factors of patients with CAD at the Makati Medical Center.
METHODOLOGY: Two hundred and one (201) patients admitted at the Makati Medical Center from July 2001 up to December 2001 with symptomatic or objective evidence of myocardial ischemia during treadmill exercise and angiographic findings of CAD were assessed. Identification and management of the different risk factors by the physicians were reviewed.
RESULTS: Of the 201 patients 167 (83 percent) were male, 65 (32 percent) were over 65 years old and 7 (3 percent) had strong family history of CAD. One hundred twenty seven (63 percent) had hypertension, 77 (38 percent) had diabetes mellitus, 96 (47 percent) had dyslipidemia, 113 (63 percent) were obese and 103 (51 percent) were smokers. Active management was done for the hypertension, diabetes and dyslipidemia. Only 39 percent of the smokers were off the habit for more than a year and only 19 percent of the obese received counseling for weight loss and exercise.
CONCLUSION: All patients identified with hypertension, dyslipidemia and diabetes mellitus were placed on appropriate diet and medications, patients with smoking problems and obesity were less consistently managed with smoking cessation approaches and weight losing manipulation through diet and exercise.

INTRODUCTION: In the Philippines, lung, breast, colon-rectum, and oral cavity cancers are among the top 10 most common cancers. This study evaluates the risk factors for these cancers among Filipinos.

METHODS: This age-matched case-control study included incident primary cancers (histologically-diagnosed) of the lung, breast (also matched for sex), colon-rectum and oral cavity. Controls (clinically free and no history of cancer) were obtained from the same tertiary hospitals as the cases. Target sample size was 283 cases and 283 controls per cancer type. Conditional logistic regression was done.

RESULTS: Exposure to cigarette/tobacco was a significant risk factor for lung (OR of current smoker compared to non-smoker [95% Confidence Interval]: 3.6 [1.6-7.9]) and oral cavity cancers (2.0 [1.2-3.3]); family history (1st degree) for lung (4.3 [1.314.2]) and breast cancers (3.0 [1.2-7.5]); every year increase in age at first pregnancy for breast cancer (1.06 [1.02-1.11]). Other risk factors for oral cavity were passive smoking (2.8 [1.6-5.1]), chewing tobacco (5.2[1.4-19.5]) and inverted cigarette smoking (3.2[1.3-8.1]). Fish sauce (patis) was found to be a protective factor for breast cancer (0.34 [0.22-0.51]) and oral cavity (0.44 [0.25-0.78]) and use of shrimp paste (bagoong) (0.48 [0.27-0.84]) for oral cavity.

CONCLUSION AND RECOMMENDATIONS: Except for family history of cancer, the identified risk factors for lung, colon-rectum, and oral cavity cancers are preventable. Proper diet and lifestyle, avoidance of cigarettes and tobacco, and environmental safety in the workplace are key cancer prevention measures. Public awareness campaign and continuing healthcare provider education must always be part of a cancer prevention program.
