Axial length, more than aging, decreases the thickness and superficial vessel density of retinal nerve fiber layer in non-glaucomatous eyes.

PURPOSE: This study seeks to build a normative database for the vessel density of the superficial retina (SVD) and evaluate how changes and trends in the retinal microvasculature may be influenced by age and axial length (AL) in non-glaucomatous eyes, as measured with optical coherence tomography angiography (OCTA). METHODS: We included 500 eyes of 290 healthy subjects visiting a county hospital. Each participant underwent comprehensive ophthalmological examinations and OCTA to measure the SVD and thickness of the macular and peripapillary areas. To analyze correlations between SVD and age or AL, multivariable linear regression models with generalized estimating equations were applied. RESULTS: Age was negatively correlated with the SVD of the superior, central, and inferior macular areas and the superior peripapillary area, with a decrease rate of 1.06%, 1.36%, 0.84%, and 0.66% per decade, respectively. However, inferior peripapillary SVD showed no significant correlation with age. AL was negatively correlated with the SVD of the inferior macular area and the superior and inferior peripapillary areas, with coefficients of -0.522%/mm, -0.733%/mm, and -0.664%/mm, respectively. AL was also negatively correlated with the thickness of the retinal nerve fiber layer and inferior ganglion cell complex (p = 0.004). CONCLUSION: Age and AL were the two main factors affecting changes in SVD. Furthermore, AL, a relative term to represent the degree of myopia, had a greater effect than age and showed a more significant effect on thickness than on SVD. This relationship has important implications because myopia is a significant issue in modern cities.

Upadacitinib for the management of bullous pemphigoid coexisting with psoriasis vulgaris: a case report and literature review.

Both bullous pemphigoid (BP) and psoriasis are common immune-related dermatological conditions in clinical practice, but the co-occurrence of these two diseases is rare. Currently, there is no consensus on the long-term safe and effective treatment for patients with both BP and psoriasis. JAK inhibitors are emerging as targeted therapeutic drugs that act by inhibiting Janus kinase activity, regulating the JAK/STAT pathway, blocking the transduction pathway of key proinflammatory cytokines, and influencing T-cell differentiation. These cytokines upstream of the JAK/STAT pathway play a pivotal role in the pathogenesis of numerous inflammatory and autoimmune disorders. Upadacitinib, a second-generation JAK inhibitor with high selectivity, demonstrates promising potential.This case report aims to provide a description of the successful treatment of bullous pemphigoid (BP) and psoriasis vulgaris by using upadacitinib, highlighting significant clinical outcomes. Additionally, we aim to analyze the underlying mechanism of upadacitinib in treating these two comorbidities by reviewing relevant literature from both domestic and international sources. Based on our clinical observations, upadacitinib appears to be a promising and well-tolerated therapeutic option for patients with concurrent BP and psoriasis, offering valuable insights for developing appropriate treatment strategies in clinical practice.

Efficacy of free gingival grafting to augment keratinized mucosa around dental implants in posterior regions after restorative procedures: A retrospective clinical study.

STATEMENT OF PROBLEM: Data on the shrinkage of free gingival grafts (FGGs) vary. Most studies have analyzed grafts in nonmolar sites because of measurement limitations and have addressed the changes in grafts and keratinized mucosa width (KMW) only in the early healing phase. PURPOSE: The purpose of this retrospective clinical study was to assess the dimensional changes of an FGG in the posterior regions and their influencing factors, with the aim of obtaining sufficient and stable KMW after restoration. MATERIAL AND METHODS: A total of 77 implants in 40 participants who had undergone an FGG surgery were recruited. Graft sizes during surgery and the surface areas of keratinized mucosa at the follow-up visit after restorations were compared by digital analysis and verified by clinical measurements and photographs. The association between shrinkage and the graft sizes, implant location, and sex and age of the participants was evaluated. The influence of the shrinkage of FGG on the KMW after restoration was analyzed by multivariable linear regression with generalized estimating equation (GEE) models. RESULTS: The mean ±standard deviation shrinkage of FGG around implants in the posterior regions was 24.76 ±14.77%, and the mean ±standard deviation KMW was 4.16 ±1.77 mm at the follow-up visit. Larger grafts had a statistically higher shrinkage ratio (P<.001). No statistically significant difference was found regarding the effect of implant location, sex, and age on the shrinkage of FGG and final KMW (P>.05). The mean ±standard deviation follow-up period after restoration was 12.45 ±7.73 months CONCLUSIONS: Free gingival grafting was found to be a predictable treatment approach for augmentation of KMW around implants in the posterior region after the fabrication of prostheses as long as grafts of sufficient size were placed. Stable outcomes were shown in the study participants in the follow-up period of up to 3 years.

Associations of decayed and filled teeth with localized stage II/III periodontitis in young adults: The CHIEF oral health study.

Background/purpose: To investigate the associations between treated and untreated dental caries and periodontitis in young adults. Materials and methods: The study enrolled 1289 participants aged 18-45 years in Taiwan. Localized periodontitis was categorized into healthy and stage II/III (n = 936 and n = 353, respectively) based on the 2017 criteria of the World Workshop. Multivariable logistic regression analysis with adjustments for sex, age, tobacco smoking status, betel nut consumption status, metabolic syndrome, and total white blood cell count was used to determine the associations. Results: Decayed tooth numbers were positively associated with localized stage II/III periodontitis [odds ratio (OR): 1.15 (95% confidence intervals (CI): 1.06-2.25)], while filled tooth numbers were inversely associated with localized stage II/III periodontitis in young adults [OR: 0.96 (95% CI: 0.92-0.99)]. Conclusion: Our study confirms the relationship between dental caries and periodontitis by direct evidence that the more decayed teeth there are, the higher the risk of periodontitis and by indirect evidence that the more treated decayed teeth there are, the lower the risk of periodontitis in young adults.

Association of hepatic and systemic inflammation with localized stage II/III periodontitis in young males: The CHIEF oral health study.

AIM: To clarify the association between systemic and hepatic inflammation and localized periodontitis which has been reported to vary among races. MATERIALS AND METHODS: The study included 1112 military males, aged 18-40 years, in Taiwan. Participants were classified as periodontally healthy/stage I (n = 796) or stage II/III periodontitis (n = 316), according to the 2017 world workshop criteria. Systemic and hepatic inflammation were defined by the highest tertiles of blood leukocyte counts (7.51 × 103 /µl) and alanine aminotransferase (30 U/L), respectively. Multiple logistic regression analysis with adjustments for age, metabolic syndrome, betel nut consumption and smoking was carried out. RESULTS: There was a significant association between high systemic inflammation, irrespective of hepatic inflammation severity, and localized stage II/III periodontitis (odds ratio [OR], 1.62 [1.09-2.42] and 1.47 [1.00-2.15], respectively, in the presence of high or no hepatic inflammation. However, no significant association was found among participants with low systemic inflammation, irrespective of the severity of hepatic inflammation (OR, 1.31 [0.91-1.91]). CONCLUSIONS: An association between hepatic inflammation and localized periodontitis in Taiwanese was observed only if systemic inflammation coexisted, possibly accounting for the reported differences in the association between Japanese and non-Asian populations in prior studies.

Court decisions in criminal proceedings for dental malpractice in Taiwan.

BACKGROUND/PURPOSE: Malpractice claims place heavy economic and emotional burdens on both dentists and patients. Recently, medical malpractice lawsuits are decreasing in prevalence but increasing in severity. The percentage of dental malpractice payments is also growing among the health profession. The present study aimed to explore criminal convictions in dental malpractice litigation and to analyze the factors affecting the judgment in dental disputes in Taiwan. METHODS: The keywords "dentist," "professional negligence," "medical malpractice," and "professional liability" were used to search Taiwan's Law and Regulations Retrieving System for criminal dental malpractice cases in all district courts from January 1, 2000 to June 30, 2021. The eligible judgments were summarized and analyzed. RESULTS: Overall, 425 cases were identified, with 28 dental disputes included in the final analysis. The dentists lost in 10 cases (35.7%). The average claim time was 36.75 ± 16.34 months. Taipei and Taichung dealt with more lawsuit cases (n = 8). Local clinics were the most common institution of the defendants (75%) and had the highest number of convictions (n = 9). Implant dentistry was the most common specialty involved. Expert testimony of the Medical Review Committee (MRC) had a high K coefficient of agreement with court judgments regarding professional negligence (p < 0.001). CONCLUSION: The overall criminal conviction rate was 35.7%. Implant therapy and local clinics had the highest rate of lawsuits and a considerably higher conviction rate. All guilty dentists were fined or given probation. The court judgments were highly consistent with the expert testimony of the MRC.

Vessel Density in the Macular and Peripapillary Areas in Preperimetric Glaucoma to Various Stages of Primary Open-Angle Glaucoma in Taiwan.

Peripapillary and macular vessel density (VD) are reduced in myopic non-glaucomatous eyes, the dynamic range of VD may be decreased by myopia, and whether VD measurement has the potential in differentiating stages of glaucoma severity in patients with myopic glaucoma remains questionable. This observational, cross-sectional study aimed to clarify the changes in peripapillary and macular VDs in preperimetric glaucoma (PPG) and primary open-angle glaucoma in the early, moderate, and late stages. A total of 1228 eyes from 661 participants (540 normal, 67 PPG, and 521 glaucomatous) were included. Participants underwent free blood tests at the internal medicine clinic to retrieve systemic data. Patients with glaucoma were grouped by disease severity, defined by glaucomatous visual field mean defect, including early-(224 eyes), moderate-(103 eyes), and late-stage glaucoma (194 eyes), and further divided into advanced (158 eyes) and terminal glaucoma (36 eyes). Macular VD, peripapillary VD, circumpapillary retinal nerve fiber layer (cpRNFL) thickness, and ganglion cell complex (GCC) thickness were evaluated and divided into superior and inferior parts. One-way analysis of variance was performed, followed by Tukey's post-hoc test. The peripapillary VD was significantly different between the healthy and PPG groups and the early-, moderate-, and late-stage glaucoma subgroups (all p < 0.001). Peripapillary VD measurements are helpful in differentiating the various stages of glaucoma even in patients with myopic glaucoma.

Associations between metabolic biomarkers and localized stage II/III periodontitis in young adults: The CHIEF Oral Health study.

AIM: To investigate the associations between metabolic risk factors and periodontitis in young adults. MATERIALS AND METHODS: The study included 1123 participants, aged 19-40 years, in Taiwan. Metabolic syndrome components were defined by the International Diabetes Federation criteria. Localized periodontitis was graded to healthy (n = 828) and stage II/III (n = 295) according to the 2017 criteria of the World Workshop. Multiple logistic regression analysis with adjustment for sex, age, betel nut consumption, and smoking were used to determine the associations. RESULTS: Greater waist circumference, serum triglycerides, and serum uric acid were associated with higher localized stage II/III periodontitis risk [odds ratio (OR) and 95% confidence interval (CI): 1.04 (1.02-1.05), 1.004 (1.002-1.006), and 1.10 (1.00-1.21), respectively]. There were no associations for total cholesterol, high-density lipoprotein, and blood pressure. There was a non-linear association between fasting glucose and localized stage II/III periodontitis, where the turning point was 105 mg/dl [OR: 0.97 (0.95-0.99) and 1.06 (1.00-1.13) when the levels were <105 and ≥105 mg/dl, respectively]. CONCLUSIONS: The risks of localized stage II/III periodontitis vary with metabolic components, in which waist circumference, serum triglycerides, and serum uric acid are the risk factors, whereas plasma glucose shows a non-linear relationship in young adults.

Body Mass Index and Association of Psychological Stress with Exercise Performance in Military Members: The Cardiorespiratory Fitness and Hospitalization Events in Armed Forces (CHIEF) Study.

AIMS: To investigate the influence of body mass index (BMI) on the association between psychological stress and physical fitness. BACKGROUND: Both obesity and psychological stress reduce exercise performance. OBJECTIVE: It is unknown whether obesity may modify the relationship. METHODS: A population of 4,080 military subjects in Taiwan was divided to three groups according to the BMI ≥27.0 kg/m2 (obesity), 24.0-26.9 kg/m2 (overweight) and 18.5-23.9 kg/m2 (normal weight). Normal, slight, and great psychological stress was evaluated by the Brief Symptoms Rating Scale (BSRS-5) score ≤5, 6-9, and ≥10, respectively. Aerobic and anaerobic fitness were respectively evaluated by time for a 3000-meter run and numbers of 2-minute sit-ups and 2-minute push-ups. Analysis of covariance (ANCOVA) with adjustments for age and sex was used to determine the relationship. RESULTS: The mean time (sec) for a 3000-meter run (standard error) under slight and great stress differed from that under normal stress in the normal weight (881.0 (11.0) and 877.9 (5.8) vs. 862.2 (1.7), p=0.089 and 0.0088, respectively) and in the obesity (928.1 (16.8) and 921.8 (10.7) vs. 895.2 (1.6), p=0.054 and 0.016, respectively), while the differences were not significant in the overweight (877.1 (12.7) and 877.5 (7.1) vs. 867.1 (2.1), both p >0.5). The impacts of the BMI on 2-minute sit-ups had a similar pattern with that on a 3000-meter run whereas the impact of the BMI on 2-minute push-ups was insignificant. CONCLUSIONS: Mental stress may not affect physical fitness in overweight military personnel. The mechanism is not clear and should be further investigated.

Retrospective evaluation of gingival thickness and tissue stability after connective tissue grafting in Asian populations: 1 month to 3.5 years.

BACKGROUND/PURPOSE: The objectives of this retrospective study are to analyze post-surgical gingival thickness after connective tissue grafting in the Asian population and to assess its tissue stability for up to approximately 3.5 years. METHODS: A total of 111 grafted teeth and 57 nearby nongrafted teeth in 28 Asian patients who had undergone connective tissue grafting surgery were selected. Gingival thickness was measured by transgingival probing. The mean gingival thickness of the grafted teeth was compared with adjacent nongrafted teeth in the same individuals. The mean gingival thickness of the grafted teeth in different tooth types and at various time intervals were statistically analyzed. RESULTS: The average gingival thickness following connective tissue grafting is 1.99 ± 0.62 mm compared to 0.96 ± 0.40 mm with nongrafted teeth (P < .0001). The maxillary premolar is the tooth type that underwent connective tissue grafting most frequently in our study. Among different tooth types, mandibular molars showed the thickest gingival tissues whereas mandibular incisors presented the thinnest tissues. No statistically significant difference in the mean tissue thickness at different time intervals was observed. CONCLUSION: Connective tissue grafting is a predictable treatment modality for gingival phenotype conversion, even in Asians, achieving nearly 2 mm of gingival thickness on average, post-operation. Tissue stability after connective tissue grafting has been presented in our study. This quantitative assessment of the gingival thickness in Asians may encourage clinicians to deal with soft tissue architecture ahead of main surgical, restorative and orthodontic treatments in order to achieve pleasing treatment outcomes.

Tobacco Smoking and Association between Betel Nut Chewing and Metabolic Abnormalities Among Military Males: The CHIEF Study.

AIM: To investigate the effect of smoking and alcohol intake on the association between betel nut chewing and each metabolic abnormality. BACKGROUND: Betel nut chewing has been associated with metabolic syndrome. OBJECTIVE: Whether the association is affected by tobacco or alcohol use is not clarified so far. METHODS: The authors conducted a cross-sectional study using 6,657 military males, aged 18-50 years in eastern Taiwan in 2013-2014. Metabolic syndrome was defined according to the International Diabetes Federation's ethnic criteria for Asians. The population was classified as non-betel nut chewers (N =5,749), current chewers with both tobacco and alcohol use (N =615), and current chewers without tobacco and/or alcohol use (N =293). Multiple logistic regression analyses were stepwise adjusted for the confounders including alcohol and tobacco use to determine the association of betel chewing with the metabolic abnormalities. RESULTS: As compared to the non-current chewers, the current chewers with both tobacco/alcohol use and those without had a higher risk of metabolic syndrome (odds ratios (OR) and 95% confidence intervals: 2.46 (2.00-3.02), and 2.04 (1.53-2.73), respectively) after controlling for age, service specialty, total cholesterol levels ≥200 mg/dL and exercise frequency (model 1). The association did not change much in the two chewing groups after additionally adjusting for alcohol consumption (model 2) (OR: 2.49 (1.99-3.12), and 2.04 (1.52-2.73), respectively), whereas the relationship reduced significantly in the chewers with both tobacco/alcohol use rather than those without after further adjusting for smoking (model 3) (OR: 2.18 (1.71-2.78) and 2.02 (1.51-2.71), respectively). This was in parallel with the pattern for the association of betel nut chewing with serum triglycerides >150 mg/dL in the chewers with both tobacco/alcohol use and those without in model 1 (OR: 2.90 (2.40-3.51) and 1.90 (1.45-2.49), respectively, p =0.011), in model 2 (OR: 2.82 (2.30-3.46) and 1.89 (1.44-2.49), respectively, p =0.040), and in model 3 (2.26 (1.81-2.81) and 1.87 (1.42-2.45), respectively, p =0.76). CONCLUSION: Our findings suggest that tobacco smoking but not alcohol intake could increase the relationship of betel nut chewing with metabolic syndrome, which is likely mediated by a synergic effect on increasing serum triglycerides levels.

Comparisons of various anthropometric indexes with localized Stage II/III periodontitis in young adults: The CHIEF oral health study.

BACKGROUND: A J-shaped relationship of body mass index (BMI) with severe periodontitis has been reported. However, it is unknown for other anthropometric indexes in young adults. METHODS: A cross-sectional study examined the relationships in 325 military men and women, aged 20 to 45 years in Taiwan. Anthropometric indexes included BMI, waist circumference (WC), and waist-to-height ratio (WHtR). The severity of localized periodontitis was defined as healthy (n = 42), Stage I (initial) (n = 228), and Stage II/III (moderate/severe) (n = 55) according to the 2017 Periodontal Diseases Classification. Smooth curve fitting and multiple logistic regression analyses adjusting for age, sex, betel nut consumption, and smoking were used to determine the threshold effect between various anthropometric and the risk of localized Stage II/III periodontitis. RESULTS: In the spline smoothing plot, the turning points for BMI, WC, and WHtR were 26.1 kg/m2 , 90.0 cm, and 0.50, respectively, and a J-shaped relationship was found for BMI (the likelihood ratio test, P <0.001). In the multiple logistic regressions, BMI ≥27.0 kg/m2 , WC ≥90.0 cm and WHtR ≥0.50 were associated with higher risk of localized Stage II/III periodontitis than their counterparts (24.0 to 26.9 kg/m2 for BMI) (odds ratios [OR] and 95% confidence intervals: 4.16 [1.39 to 12.49], 2.65 [1.01 to 7.11], and 2.95 [1.20 to 7.24], respectively; all P values <0.05). However, the risk for BMI <24.0 kg/m2 was not significant (OR, 1.47 [0.47 to 4.54]). CONCLUSION: In young adults, obesity defined by various anthropometrics was consistently associated with localized Stage II/III periodontitis and a J-shaped association was suggestive for BMI.

Comparisons of traditional electrocardiographic criteria for left and right ventricular hypertrophy in young Asian women: The CHIEF heart study.

The performance of electrocardiographic (ECG) voltage criteria to identify left and right ventricular hypertrophy (LVH and RVH) in young Asian female adults have not been clarified so far.In a sample of 255 military young female adults, aged 25.2 years on average, echocardiographic LVH was respectively defined as the left ventricular mass (LVM) indexed by body surface area (BSA) (≥88 g/m) and by height (≥41 g/m), and RVH was defined as anterior right ventricular wall thickness >5.2 mm. The performance of ECG voltage criteria for the echocardiographic LVH and RVH were assessed by area under curve (AUC) of receiver operating characteristic (ROC) curve to estimate sensitivity and specificity.For the Sokolow-Lyon (the maximum of SV1 or SV2 + RV5 or RV6) and Cornell (RaVL + SV3) voltage criteria with the LVM/BSA ≥88 g/m, the AUC of ROC curves were 0.66 (95% confidence intervals [CI]: 0.52-0.81, P = .039) and 0.61 (95% CI: 0.44-0.77, P = .18), respectively. For these 2 ECG voltage criteria with the LVM/height ≥41 g/m, the AUC of ROC curves were 0.64 (95% CI: 0.52-0.75, P = 0.11) and 0.73 (95% CI: 0.61-0.85, P = 0.0074), respectively. The best cut-off points selected for the Sokolow-Lyon and Cornell voltage criteria with echocardiographic LVH in young Asian females were 26 mm and 6 mm, respectively. In contrast, all the AUC of ROC curves were less than 0.60 and not significant according to the Sokolow-Lyon (the maximum of RV1 + SV5 or V6) and Myers' voltage criteria (eg, the voltage of R wave in V1 and the ratios of R/S in V1, V5 and V6) with echocardiographic RVH.There was a suggestion that the ECG voltage criteria to screen the presence of LVH should be adjusted for the young Asian female adults, and with regard to RVH, the ECG voltage criteria were found ineffective.

Modified paramedian versus conventional paramedian technique in the residency training: an observational study.

BACKGROUND: Residency training includes positive and negative aspects. Well-trained doctors must be educated, but the process may bring additional risks to patients. Anesthesiologists' performance when conducting neuraxial anesthesia is related to their experience. We hypothesized that a modified neuraxial anesthesia method would improve both residency training and patient safety. METHODS: We recruited 518 patients who were scheduled for a cesarean section and used spinal anesthesia (n = 256), epidural anesthesia (n = 154), and combined spinal-epidural anesthesia (SEA; n = 108). We observed and evaluated the anesthesia performance of five second-year resident anesthesiologists in elective cesarean sections using the conventional and modified methods. The number of attempts, implant error rate, and the incidence of complications were recorded and analyzed. RESULTS: Better success puncture attempts occurred in all three groups when the modified method was applied. For the groups with an implant assessment, the complication rate and implant error rate were lower when using the modified method. We employed generalized estimating equation (GEE) analysis to correct for possible confounding factors. When using the conventional method, the resident anesthesiologists required more attempts, made more implant errors, and caused more complications in patients. CONCLUSIONS: We found that a modified method for neuraxial anesthesia could improve residency performance and patient safety. The modified method may be a suitable training process for resident anesthesiologists when practicing neuraxial anesthesia. TRIAL REGISTRATION: The study was approved by the Research Ethics Committee of National Taiwan University (IRB:200812040R) Clinicaltrials register: NCT03389672 .

Sex-specific association of hyperuricemia with cardiometabolic abnormalities in a military cohort: The CHIEF study.

Hyperuricemia has been associated with metabolic syndrome, and the association with various cardiometabolic risk factors may be affected by sex.We made a cross-sectional examination in a military cohort of 6738 men and 766 women, aged 18 to 50 years of Taiwan in 2013 to 2014. Hyperuricemia were defined as serum uric acid levels ≥7.0 mg/dL for men and ≥5.7 mg/dL for women, respectively. Multivariable logistic regression analyses were used to determine the associations between hyperuricemia and various metabolic abnormalities.In the overall population, hyperuricemia was associated with high blood pressure (odds ratio [OR]: 1.59, and 95% confidence intervals: 1.42-1.77), low high-density lipoprotein (OR: 1.75, 1.56-1.97), high triglycerides (OR: 2.14, 1.90-2.42), high low-density lipoprotein (OR: 1.71, 1.51-1.93), high fasting plasma glucose (OR: 1.29, 1.13-1.48), and central obesity (OR: 2.85, 2.55-3.18) after adjusting for age and serum creatinine concentrations. However, the associations with atherogenic lipid profiles including high triglycerides and high low-density lipoprotein were merely significant in men but not in women. In addition, there was a tendency for a sex difference in the association of hyperuricemia and raised blood pressure ≥130/85 mm Hg, which was greater in women than that in men (OR: 2.92, 1.37-6.25 and 1.54, 1.37-1.72, respectively; P for interaction = .059).Our findings suggest that the association between hyperuricemia and various cardiometabolic abnormalities in young adults may differ by sex, possibly due to a regulation of sex hormones and uneven effects of uric acid at the same levels between sexes on lipid metabolisms and arterial stiffness.

Association of Tobacco Smoking with Physical Fitness of Military Males in Taiwan: The CHIEF Study.

Tobacco smoking has been found associated with lower cardiorespiratory fitness in white and black males; however, few studies have not been conducted to clarify such relationship in Asian males. We performed a cross-sectional study to investigate the association between tobacco smoking status and physical fitness in 3,669 military males, averaged 29.4 years of age, from the cardiorespiratory fitness and hospitalization events in armed forces (CHIEF) study in Taiwan during 2014. There were 1,376 current smokers, and the others were noncurrent smokers. The effective sample size estimated was 1,230 participants, as the margin of error was ±3% at the 99% confidence level. Physical fitness was evaluated by time for a 3000-meter run test (aerobic fitness) and repetitive numbers of 2-minute sit-ups and 2-minute push-ups (anaerobic fitness) where all procedures were standardized by using computerized scoring systems. A multiple linear analysis adjusting for age, service specialty, body mass index, heart rate, alcohol intake, and training frequency was used to determine the relationship. As compared with noncurrent smoking, current smoking was inversely correlated with longer time for a 3000-meter run (ß = 15.66 (95% confidence intervals (CI): 10.62, 20.70)) and fewer repetitive numbers of 2-minute sit-ups and 2-minute push-ups (ß = -1.53 (95% CI: -2.08, -0.97) and -1.31 (95% CI: -2.12, -0.50), respectively). Our finding reconfirms the concept that tobacco smoking might reduce both aerobic and anaerobic fitness among young Asian males.

Quantitative Physical Fitness Measures Inversely Associated With Myopia Severity in Military Males: The CHIEF Study.

Myopia has been linked to body weight and sedentary status, but the association with quantitatively measured physical fitness in adults has not been examined. Cross-sectional analyses were performed to investigate the association between physical fitness and myopia in 3,669 military men (aged 29.4 years) in Taiwan. The severity of myopia obtained from the left eye was classified as mild (-0.5 to -3.0 diopters; n = 544), moderate -3.1 to -6.0 diopters; n = 563), and high (<-6.0 diopters; n =150); others were defined as nonmyopia (n = 2,412). Aerobic fitness was evaluated by time for a 3000-meter run test, and muscular endurance was evaluated by numbers of 2-min sit-ups and 2-min push-ups. A value of p < .0125 was considered significant. A multiple linear regression analysis was used to determine the relationship. Individuals who were less physically fit had higher risk of myopia. The associations were dose-dependently significant with mild, moderate, and high myopia for 3000-meter running time (ß = 9.64; 95% confidence intervals [3.22, 16.05], ß = 12.41; 95% CI [6.05, 18.76], and ß = 20.87; 95% CI [9.22, 32.51], respectively) after controlling for the potential covariates. There tended to be an inverse association with moderate and high myopia for numbers of 2-min push-ups (ß = -1.38; 95% CI [-2.43, -0.34] and ß = -2.10; 95% CI [- 3.97, -0.22], respectively) and 2-min sit-ups (ß = -0.83; 95% CI [-1.54, -0.12] and ß = -1.29; 95% CI [-2.56, -0.02], respectively), respectively. This study suggested that physical fitness, particularly aerobic fitness of the military males who received regular training, is inversely associated with myopia severity, independent of service specialty, body mass index, and educational level.

Evidence-based prophylaxis strategies for postoperative nausea and vomiting when considering ethnicity factor.

In most western countries, postoperative nausea and vomiting (PONV) is an important issue and prophylaxis guideline for PONV will be followed in clinical practice. We tried to conduct a review study and a local study to elucidate the incidence and severity of PONV to see if considering ethnicity factor, should we still need to follow those prophylaxis guidelines from western countries. The PubMed, and MEDLINE were consulted from January 2000 to 2018 and also Cochrane Central Register of Controlled Trials (CENTRAL 2010). The key word for searching is PONV (incidence, severity and prevention strategy), without language limitation and focus on Asian countries. The results showed that the overall incidence and severity of PONV in Asian countries was less significant than in western countries. PONV in western countries could be a serious issue and prophylaxis strategy adjusted by Apfel score could be adopted in routine practice. After this review consultation, the issue of PONV in different ethnic countries (including Taiwan) might be over emphasized and we may suggest not to follow west countries PONV prophylaxis guideline as our routine practice.

Reinforcement of patient education improved physicians' adherence to guideline-recommended medical therapy after acute coronary syndrome.

BACKGROUND: Prescription of guideline-recommended medicines after acute coronary syndrome (ACS) has been suboptimal. Tools for improving the use of medications have been developed, but they mainly targeted physicians. OBJECTIVE: We evaluated the effects of reinforcement of patient and family education on the usage of guideline-recommended secondary prevention medications. METHODS: This was a retrospective analysis of a prospectively collected registry of patients with ACS who were admitted to a regional teaching hospital in Taiwan between February 2015 and April 2017. The control group included 76 patients discharged before implementing the electronic-based patient and family education (PFE) system. The intervention group included 206 patients discharged after implementation. The primary outcome was the prescription rate of all four guideline-recommended drugs. Predictors of adherence were also evaluated. RESULTS: The study cohort included 282 ACS patients (188 men and 94 women) with a mean age of 68.5 years (standard deviation, 14.2). The intervention group patients were younger, had more family history of premature cardiovascular disease, more dyslipidemia, and underwent more reperfusion therapy. The intervention group was prescribed more guideline-recommended drugs than the control group: dual antiplatelet agents, 79.61% vs. 47.37% (p<0.001); statins, 74.76% vs. 34.21% (p<0.001); beta-blockers, 81.07% vs. 46.05% (p<0.001); angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, 62.62% vs. 38.16% (p<0.001); and a combination of all four medications, 39.32% vs. 14.47% (p<0.001). After adjusting baseline variables, the PFE system remained a significant contributor to adherence to these drugs use (P = 0.02). CONCLUSIONS: Reinforcement of patient education was associated with significant improvements in physicians' adherence to guideline-recommended medical therapy after acute coronary syndrome.

Association of electrocardiographic left and right ventricular hypertrophy with physical fitness of military males: The CHIEF study.

AIM: To investigate the association of electrocardiographic (ECG) left and/or right ventricular hypertrophy (LVH and RVH) with physical fitness of military males. METHODS: We used a military cohort of 2587 males, who were on average 29.1 years of age, from the cardiorespiratory fitness and hospitalization events in armed forces (CHIEF) study in Taiwan for the analysis. Isolated ECG-LVH (n = 779) was diagnosed by either the Sokolow-Lyon or Cornell voltage criteria. Isolated ECG-RVH (n = 234) was defined by either the Sokolow-Lyon or Myers et al. voltage criteria. Combined ECG-LVH/RVH (n = 140) was defined as those who met the voltage criteria for both LVH and RVH. The other ECGs were defined as unaffected (n = 1434). Physical fitness was evaluated by the upper and lower 16% exercise performance (beyond 1-standard deviation) in 3000-meter run, 2-minute sit-ups, and 2-minute push-ups. All procedures were standardized and monitored by unified computerized scoring systems. A multiple logistic regression was used to determine the relationship. RESULTS: Compared with unaffected participants, those with an isolated ECG-LVH were tended to have a better 3000-meter run performance (odds ratio (OR) and 95% confidence intervals: 1.22 [0.99-1.50], p-value = 0.064) after adjusting for age, service specialty, body mass index, mean blood pressure, smoking status, alcohol intake, hemoglobin level, and exercise frequency. By contrast, those with an isolated ECG-RVH were tended to have a worse 2-minute sit-up performance (OR: 1.46 [0.99-2.16], p-value = 0.054). CONCLUSION: Military males with ECG-LVH and/or ECG-RVH compared to unaffected participants may have diverse exercise performances. However, these observations narrowly failed to reach statistical significance.
