Normal 2-Dimensional Strain Values of the Left Ventricle: A Substudy of the Normal Echocardiographic Measurements in Korean Population Study

BACKGROUND: It is important to understand the distribution of 2-dimensional strain values in normal population. We performed a multicenter trial to measure normal echocardiographic values in the Korean population. METHODS: This was a substudy of the Normal echOcardiogRaphic Measurements in KoreAn popuLation (NORMAL) study. Echocardiographic specialists measured frequently used echocardiographic indices in healthy people according to a standardized method at 23 different university hospitals. The strain values were analyzed from digitally stored images. RESULTS: Of a total of 1003 healthy participants in NORMAL study, 2-dimensional strain values were measured in 501 subjects (265 females, mean age 47 ± 15 years old) with echocardiographic images only by GE echocardiographic machines. Interventricular septal thickness, left ventricular (LV) posterior wall thickness, systolic and diastolic LV dimensions, and LV ejection fraction were 7.5 ± 1.0 mm, 7.4 ± 1.0 mm, 29.9 ± 2.8 mm, 48.9 ± 3.6 mm, and 62 ± 4%, respectively. LV longitudinal systolic strain (LS) values of apical 4-chamber (A4C) view, apical 3-chamber (A3C) view, apical 2-chamber (A2C) view, and LV global LS (LVGLS) were −20.1 ± 2.3, −19.9 ± 2.7, −21.2 ± 2.6, and −20.4 ± 2.2%, respectively. LV longitudinal systolic strain rate (LVLSR) values of the A4C view, A3C view, A2C view, and LV global LSR (LVGLSR) were −1.18 ± 0.18, −1.20 ± 0.21, −1.25 ± 0.21, and −1.21 ± 0.21(−s), respectively. Females had lower LVGLS (−21.2 ± 2.2% vs. −19.5 ± 1.9%, p < 0.001) and LVGLSR (−1.25 ± 0.18(−s) vs. −1.17 ± 0.15(−s), p < 0.001) values than males. CONCLUSION: We measured LV longitudinal strain and strain rate values in the normal Korean population. Since considerable gender differences were observed, normal echocardiographic cutoff values should be differentially applied based on sex.

Normal Echocardiographic Measurements in a Korean Population Study: Part II. Doppler and Tissue Doppler Imaging

BACKGROUND: Hemodynamic and functional evaluation with Doppler and tissue Doppler study as a part of comprehensive echocardiography is essential but normal reference values have never been reported from Korean normal population especially according to age and sex. METHODS: Using Normal echOcaRdiographic Measurements in a KoreAn popuLation study subjects, we obtained normal reference values for Doppler and tissue Doppler echocardiography including tricuspid annular velocities according to current guidelines and compared values according to gender and age groups. RESULTS: Mitral early diastolic (E) and late diastolic (A) velocity as well as E/A ratio were significantly higher in women compared to those in men. Conversely, mitral peak systolic and late diastolic annular velocity in both septal and lateral mitral annulus were significantly lower in women compared to those in men. However, there were no significant differences in both septal and lateral mitral early diastolic annular (e') velocity between men and women. In both men and women, mitral E velocity and its deceleration time as well as both E/A and E/e' ratio considerably increased with age. There were no significant differences in tricuspid inflow velocities and tricuspid lateral annular velocities between men and women except e' velocity, which was significantly higher in women compared to that in men. However, changes in both tricuspid inflow and lateral annular velocities according to age were similar to those in mitral velocities. CONCLUSION: Since there were significant differences in Doppler and tissue Doppler echocardiographic variables between men and women and changes according to age were even more considerable in both gender groups, normal Doppler echocardiographic values should be differentially applied based on age and sex.

Morphological Characteristics of Normal and Gynandromorphic Hyalomma asiaticum Schulze and Schlottke, 1930

Gynandromorphic ticks are extremely rare, and often attract parasitologists' attention. During our examination of tick specimens, an engorged gynandromorph of Hyalomma asiaticum was noticed. This is the first record of gynandromorphic ticks from China. In this study, several important morphological structures of normal and gynandromorphic H. asiaticum were analyzed. Comparing to the normal H. asiaticum, the gynandromorphic specimen was a typical bipartite protogynander. Its right side showed normal female characteristics, whereas the left side had normal male traits. Different from other gynandromorphic ticks containing 1 anus, this tick reported here had 2 complete anuses, and the anus of the male part had a single adanal plate.

Normal Echocardiographic Measurements in a Korean Population Study: Part I. Cardiac Chamber and Great Artery Evaluation

BACKGROUND: Measurement of the cardiac chamber is essential, and current guidelines recommend measuring and reporting values for both sides of the cardiac chamber during echocardiographic evaluation. Normal echocardiographic reference values have been suggested previously, but detailed information about right-sided chambers and values according to gender was not included. METHODS: This is a prospective multicenter (23 centers) study evaluating normal Korean adult subjects using comprehensive echocardiography. We included normal adult subjects (age; 20-79 years old) who had no significant cardiac disorders or illnesses, such as hypertension or diabetes, which could affect cardiac structure and function. We measured the cardiac chamber including both right and left ventricles as well as atria according to current echocardiography guidelines and compared values according to gender and age groups. RESULTS: A total of 1003 subjects were evaluated and the mean age was 48 +/- 16 years. Left ventricular (LV) dimensions increased, but LV volume decreased in older subjects. Right ventricular (RV) area decreased in women and older subjects, and the RV long-axis dimension showed a similar trend. Left atrial (LA) volume increased in men but there were no differences in LA volume index between men and women. The dimension of great arteries increased in men and older subjects. CONCLUSION: Since there were considerable differences between men and women and in the different age groups, and the trends differed significantly between different echo variables, normal echocardiographic cutoff values should be differentially applied based on age and gender.

Personality assessment of offenders and mentally ill offenders

Background: Crime is a complex psychological, sociological and situational behaviour. Personality theories provide possible insights into the psychological aspects of crime. The primary assumption behind the personality theories is that crime and delinquency are related to the presence of some personality traits. Aims: To assess the personality dimensions of offenders, mentally ill offenders and to compare them with normal control population. Methods: A semi-structured interview consisting of Socio-demographic details, Eysenck Personality Questionnaire (EPQ) and Barratt Impulsiveness Scale (BIS-11) were used to assess the personality of offenders, mentally ill offenders and normal population. Results: Offenders with and without mental illness did not differ in their personality, but both the groups differed significantly with the personality of general population. The offenders were more impulsive compared to normal population in general and offenders with mental illness were scoring high on total BIS-11 score and on non-planning impulsivity score compared to normal offenders. Conclusion: Personality traits can predict the person’s vulnerability to commit an offence.

Distribution of bacterial flora in sigmoid colon tissues and stools in normal population / 中华临床营养杂志

Objective To study the distribution patterns of bacterial flora in sigmoid colon tissues and stools in normal population.Method Bacterial flora were identified and analyzed by using 16sDNA sequencing technology in fresh stool samples (n =13) and colon mucosa samples (n =10).Results The diversity and abundance of bacterial flora were significantly larger in the stool samples than in the sigmoid colon samples (P ＜ 0.001,P ＜ 0.001,P =0.042,P =0.006).The consititution of phylum flora between the two groups were same,including flrmicutes,bacteroides,proteobacteria,and actinomycetes.However,the proportions of firmicutes and bacteroides in stool samples were significantly higher than in the sigmoid colon samples,whereas the proportion of proteobacteria was significantly lower (P ＜ 0.001,P =0.025,P ＜ 0.001).At the genus level,faecalibacterium and bacteroides were the dominant flora in feces,whereas pseudomonas,lactococcus,acinetobacter,and flavobacterium were the most common flora in sigmoid colon mucosa.The amounts of bifidobacterium and lactobacillus were low in both two groups.Conclusion The distribution of bacterial flora remarkably differ in stools and sigmoid colon mucosa.

Corneal sensitivity in normal Thai population.

ObjectiveTo measure corneal sensitivity in normal Thai people of different ages using the Cochet – Bonnet aesthesiometer. Methods: This prospective, cross-sectional study was conducted with three hundred normal Thai subjects (600 eyes) who were divided into six groups according to their age. Corneal sensitivity was measured by using a Cochet – Bonnet aesthesiometer at the central cornea. The mean filament length of three measurements was considered to be the corneal sensitivity threshold. Results: There were statistically significant differences in the mean corneal sensitivity of the central cornea among age groups (p < 0.0001). The mean corneal sensitivity decreased with advancing age, and was significantly reduced after the age of sixty. Conclusion: The normal value of corneal sensitivity of the central cornea in the Thai population is the same as those of previous reports from other countries. Normal corneal sensitivity significantly decreased after the age of sixty.

Frequência de anticorpos anti-Cysticercus cellulosae em população de risco para cisticercose e em segmento de população considerado supostamente normal, em regiões do Estado de São Paulo, Brasil / Frequency of anti-cysticercus cellulosae antibodies in high risk population for cysticercosis and in a segment considered as normal population, in areas of Säo Paulo state, Brazil

Examinaram-se, através de reação de fixação de complemento, os soros de 234 pacientes internados em hospital psiquiátrico localizado no município de Presidente Prudente, considerados de risco para infecção cisticercótica, além de 454 soros de gestantes procedentes da Região Administrativa de Santos e 397 soros de indivíduos considerados supostamente normais, procedentes da Região Administrativa de Presidente Prudente. O antígeno utilizado na reação de fixação de complemento foi obtido através de extração metílica, à temperatura ambiente, dos císticercos tratados com acetona. Consideraram-se positivas as reações em que ocorreu fixação de complemento a partir da diluição 1 :2. Dos 1.085 soros testados, 27 apresentaram atividade anticomplementar e 17 (1,6%) mostraram-se reagentes. Todavia, quando se consideraram, separadamente, os grupos procedentes de Santos, Presidente Prudente e os doentes mentais, percebe-se diferença significativa nos resultados: assim, os índices de freqüência foram, respectivamente, 0,88% e 1,00% para os indivíduos procedentes de Santos e Presidente Prudente e considerados supostamente normais e 3,8% para os doentes mentais. Os resultados indicam que não é desprezível a ocorrência de anticorpos anti-Cysticercus cellulosae em nosso meio, especialmente entre pacientes de hospitais psiquiátricos (AU).
