Dietary triglycerides influence the serum concentrations of fatty acids (FA) and their weight percentages (wt%), which might be associated with the age of onset of intracerebral hemorrhage (ICH). We investigated the correlation between serum FA levels and proportions at admission, and the age at onset of ICH. We included patients admitted between 2016 and 2019 within 24 h of the onset of ICH, and calculated the correlation coefficients between their age, serum FA concentration, and FA wt%. We performed multiple linear regression analysis to identify individual FAs related to the age at onset of ICH. Furthermore, we estimated the threshold values of FAs that were independently associated with the age at onset of ICH <65 years, using receiver operating characteristic curves by logistic regression. Our inclusion criteria were met by 141 patients (mean age, 67 years). The concentration of dihomo-gamma-linolenic acid (DGLA) and the wt% of eicosapentaenoic acid (EPA) were significant independent variables for the age at onset of ICH. The ROC curves for the age of onset <65 years were ≥108.6 µmol/L for DGLA and ≤1.7% for EPA. Increased DGLA concentration and decreased EPA wt% were significantly associated with young-onset ICH.

Dietary triglycerides influence fatty acid (FA) serum concentrations and weight percentages (wt %), which may be associated with the age of onset of acute ischemic stroke (AIS). We investigated the correlations between serum FA levels and proportions at admission and the age of onset of AIS. We evaluated patients with AIS admitted between 2016 and 2019 within 24 h of AIS onset and calculated the correlation coefficients between their ages, serum FA concentrations, and FA wt % values. Multiple linear regression analysis was performed to identify independent FAs indicating AIS age of onset. Furthermore, we estimated the threshold values of independent FAs for age of onset <60 years using receiver operating characteristic curves by logistic regression. A total of 525 patients (median age: 75 years) met the inclusion criteria. The concentration of dihomo-gamma-linolenic acid (DGLA) and wt % of docosahexaenoic acid (DHA) were significant independent variables for age of onset of AIS, and receiver operating characteristic curves for age of onset <60 years showed thresholds of ≥117.7 µmol/L for DGLA and ≤3.7% for DHA. An increased DGLA concentration and decreased DHA wt % were significantly associated with onset of AIS at a younger age.

Abstract Background: To evaluate the reliability and diagnostic efficacy of the ultrasound grayscale ratio (UGSR) for differentiating papillary thyroid microcarcinomas (PTMC) from micronodular goiters (diameter ≤ 1.0cm).Methods: The ultrasound data of 241 pathologically-confirmed cases of patients with 265 PTMC and 141 patients with 168 micronodular goiters were retrospectively reviewed. All patients underwent outpatient ultrasonic examination and preoperative ultrasonic positioning. The RADinfo radiograph reading system (Zhejiang RAD Information Technology Co., Ltd., China) was used to measure and calculated the UGSR of PTMC, micronodular goiters. Patients were divided into the outpatient examination, preoperative positioning, and mean value groups, and the receiver operating characteristic curves (ROC) were calculated to obtain the optimal UGSR threshold for distinguishing PTMC from micronodular goiters.Results: The UGSR values of the PTMC and micronodular goiters were 0.56±0.14 and 0.80±0.19 (t=5.84, P<0.01) in the outpatient examination group, 0.55±0.14 and 0.80±0.19 (t=18.74, P<0.01) in the preoperative positioning group, and 0.56±0.12 and 0.80±0.18 (t=16.49, P<0.01) in the mean value group. The areas under the ROC curves in the outpatient examination, preoperative positioning, and mean value groups were 0.860, 0.856, and 0.875, respectively. When the cut-off UGSR values for the outpatient examination, preoperative positioning, and mean value groups were 0.649, 0.646, and 0.657, the sensitivity and specificity for predicting PTMC were 78.9% and 86.9%, 79.2% and 83.9%, 82.6%, and 85.7%, respectively. A reliable UGSR value was obtained between the outpatient examination and preoperative positioning groups (ICC=0.79, P=0.68).Conclusion: The UGSR is an accurate and feasible tool for differentiating PTMC from micronodular goiters with better diagnostic efficacy.

Affective Temperament

Affective temperaments represent a biologically stable core of emotional reactivity and have previously been associated with hypertension and arterial stiffening. The age, when hypertension is initiated, is influenced by different factors, but the role of personality traits in this regard is not clarified yet. Our aim was to study the association between affective temperaments and the age at onset of hypertension. In this cross-sectional study, 353 patients were included. After the evaluation of history, patients completed the Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire. We used linear regression analysis to identify predictors of the age of onset of hypertension in the whole cohort and in male and female subpopulations. The independent predictors of the age at onset of hypertension were male sex (B = −4.57 (95% CI = −1.40 to −7.74)), smoking (B = −4.31 (−7.41 to −1.22)), and positive family history (B = −6.84 (−10.22 to −3.45)). In women, cyclothymic temperament score was an independent predictor of the initiation of hypertension (B = −0.83 (−1.54 to −0.12)), while this association was absent in men. Besides traditional factors, cyclothymic affective temperament might contribute to the earlier initiation of hypertension in women.

El trastorno de compulsión alimentar periódico (TCAP) está vinculado a varios trastornos psiquiátricos, como los de ansiedad. Aproximadamente el 50-60% de los pacientes con TCAP son resistentes a los tratamientos tradicionales disponibles y, por lo tanto, se necesitan estrategias que apoyen el tratamiento de TCAP, como la actividad física (AF). La práctica de AF parece ser una estrategia interesante para reducir TCAP y síntomas de ansiedad. Por lo tanto, dado que la AF tiene un papel en la reducción de los episodios de TCAP y en la mejora de los síntomas de ansiedad, entonces se necesita más investigación para aclarar el rol moderador de la AF en la TCAP, ya que se establecen correlaciones entre ansiedad-TCAP y ansiedad-AF. Por lo tanto, el objetivo de este estudio fue examinar la asociación entre AF y ansiedad en pacientes con TCAP. Treinta y dos pacientes fueron sometidos a cuestionarios psicológicos y de AF. Se realizaron un coeficiente de correlación de Pearson y un análisis de regresión lineal múltiple para relacionar el comportamiento del TCAP, la ansiedad y la AF. Los coeficientes de correlación entre las dimensiones del TCAP y ansiedad fueron casi todos significativos (excepto restricción), positivos y moderados (p <0.001). Por lo tanto, cuanto más altos sean los valores del TCAP, mayores serán los niveles de ansiedad (p <0.01). En conclusión, nuestros hallazgos respaldan que la PA se correlaciona con la ansiedad en pacientes con BED, lo que sugiere que la PA puede disminuir los síntomas, como las preocupaciones sobre el apetito, el peso y la forma del cuerpo. Binge-eating disorder (BED) is linked to several psychiatric disorders, such as anxiety disorders. Approximately 50-60% of BED patients are resistant to the traditional treatments available, and thus, strategies supporting the treatment of BED are needed, such as physical activity (PA). It seems to be an interesting strategy to reduce BED and anxiety symptoms. Thus, since PA has a role in reducing BED episodes and improving anxiety symptoms, then more research is needed to clarify the role of PA on BED, as correlations between anxiety-BED and anxiety-PA are established. Therefore, our aim is to examine the relationship between PA and anxiety in patients with BED. Thirty two patients we submitted to psychological and PA questionnaires. A Pearson's correlation coefficient and a multiple linear regression analysis were performed to relate eating disorder behaviour, anxiety and PA. The correlation coefficients between the dimensions of BED and anxiety were almost all significant (except restriction), positive and moderate (p<0.001). Thus, the higher the eating disorder values, the higher the anxiety levels (p<0.01). In conclusion, our findings support that PA correlates with anxiety in patients with BED, suggesting that PA may decrease symptoms, such as the appetite, weight and body shape concerns.

Aproximadamente 50-60% dos pacientes com TCAP são resistentes aos tratamentos tradicionais disponíveis e, portanto, são necessárias estratégias de apoio ao tratamento, como a atividade física (AF). Parece ser uma estratégia interessante para reduzir os sintomas da TCAP e da ansiedade. Assim, como a AF tem um papel na redução de episódios de TCAP e melhora dos sintomas de ansiedade, são necessárias mais pesquisas para esclarecer o papel da AF na TCAP, à medida que são estabelecidas correlações entre ansiedade-TCLE e ansiedade-PA. Portanto, nosso objetivo é examinar a relação entre AF e ansiedade em pacientes com TCAP. Trinta e dois pacientes foram submetidos a questionários psicológicos e de AF. Um coeficiente de correlação de Pearson e uma análise de regressão linear múltipla foram realizadas para relacionar comportamento de transtorno alimentar, ansiedade e AF. Os coeficientes de correlação entre as dimensões do TCAP e ansiedade foram quase todos significativos (exceto restrição), positivos e moderados (p <0,001). Assim, quanto maiores os valores do transtorno alimentar, maiores os níveis de ansiedade (p <0,01). Em conclusão, nossos achados sustentam que a AF se correlaciona com a ansiedade em pacientes com TCAP, sugerindo que a AF pode diminuir os sintomas, como preocupações com apetite, peso e forma corporal.

Purpose: This retrospective study measured correlation of student performance between 2 objective structured clinical examinations (OSCEs) and an introductory integrated clinical skills course that preceded the OSCEs. The hypothesis was that there would be a strong, positive correlation between the earlier level examinations and the upper level OSCE, high enough that earlier examinations could be viewed as predictors of upper level OSCE performance. Methods: Using student scores for 5 academic terms of upper level OSCEs for 2008–2009 (n = 208) and respective earlier scores, correlation coefficients were calculated for the upper level OSCE and Clinical Skills course, and upper and lower level OSCEs. Multiple linear regression analysis was used to evaluate how well the lower level OSCE and clinical skills scores, both as lone and combined independent variables, predicted the upper level OSCE scores. Results: There was at least a moderate correlation between both sets of scores: r = .51 (p &lt; .001) between upper level OSCE and clinical skills course, r = .54 (p &lt; .001) between the upper and lower level OSCEs. A combination of clinical skills and lower level OSCE scores suggested a moderate prediction of upper level OSCE scores (R2 = .38.) Conclusions: Correlations were found to be of at least a moderate level. According to linear regression analysis, a combination of the earlier scores was moderately predictive for the upper level OSCE. More research could be done to determine additional components of student performance.

The Relationship

Background. Metabolic syndrome (MetS) is associated with the risk of developing chronic kidney disease. Although the negative effects of high thyroid-stimulating hormone (TSH) values on glomerular filtration rate (GFR) levels have been known for years, the negative effects of increased TSH on GFR in euthyroid cases have been reported in recent years. This study was aimed at investigating the association between the effect of increased TSH values and estimated-GFR (eGFR) levels in euthyroid cases with MetS. Methods. For this hospital-based descriptive study, 191 MetS cases (123 females, 68 males) were evaluated. Those whose TSH was not within 0.5–4.5 uIU/mL, eGFR was <40 mL/min/1.73 m2, and/or reported any thyroid/kidney disease were excluded. Partial correlation coefficients were calculated to investigate the relationship between the eGFR values and several other numerical variables while controlling for age and BMI in addition to the adjusted gender effect. Thereafter, the multiple linear regression analysis with a stepwise variable selection approach was used to reveal the independent factors that could affect the logarithmically transformed eGFR. Results. The median age was 52 (19–65) years, the median eGFR was 94.3 (41.3–194) mL/min/1.73 m2, and the median TSH was 1.58 (0.50–4.50) uIU/mL in the whole group. Increased TSH even in the normal range was associated with eGFR after adjusting for age and body mass index (BMI), especially in females. The high age (b = −0.160, p = 0.005 ), high BMI (b = −0.134, p = 0.020 ), high TSH (b = −0.380, p < 0.01 ), and high uric acid (b = −0.348, p < 0.01 ) were found as significant predictors of the eGFR in MetS patients. Conclusion. Independent of age and BMI, elevated TSH even in the euthyroid range showed an association with the eGFR in female MetS cases who had normal kidney functions. This correlation was stronger than the correlations between the eGFR and the MetS diagnostic parameters. These findings need further studies on the issue..

The Stability

Since we intended to use the respiratory inductance plethysmograph (RIP) to study breathing patterns in a single body position, we developed a method to calibrate the RIP in one position (seated) and verified the stability of this calibration procedure during a 60-min period. The subject breathed spontaneously through a pneumotachograph for 1 min during all calibration and verification runs. All inspiratory data from the abdomen and rib cage RIP transducers was analyzed using multiple linear regression analysis to calculate calibration factors for the transducers. Eight normal subjects were studied, and the stability of calibration at 20, 40, and 60 min was determined. The correlation coefficients were all greater than 0.94. The mean slope and mean intercept describing the relationship of the RIP volume to the pneumotachograph volume for all calibration and verification runs were 0.995 +/- 0.074 and 0.012 +/- 0.018 liter, respectively. This calibration method allows a spirogram to be generated from the RIP signals. Therefore, this technique may be valuable in further investigating resting breathing patterns in humans.

Abstract Serum (1→3)-β-D-glucan (BDG), is an adjunct test in the diagnosis of invasive fungal disease (IFD). Fungitell STAT™, a facile, rapid, single patient option, executable for one or more patient specimens in approximately an hour, has been developed to address a need for rapid in-house testing. This method presents qualitative information concerning serum BDG levels, using an index value that allows the rapid categorization of patients as positive, negative, or indeterminate relative to serum BDG titer. The categorical and analytical performance of Fungitell STAT was evaluated. The categorical agreement between methods was established by testing patient samples which had been previously categorized with Fungitell. Receiver Operating Characteristic curves were used to identify cut-offs using 93 de-identified patient specimens. Subsequently, using these cutoffs, an independent group of 488 patient specimens was analyzed. Positive percent agreement (PPA) with, and without, indeterminate results was 74% and 99%, respectively. Negative percent agreement (NPA) was 91% and 98% with, and without, indeterminate results, respectively. Additionally, commercially available normal off-the-clot sera were spiked with Saccharomyces cerevisiae-derived (1→3)-β-D-glucan to produce analytical samples. Analytical reproducibility using spiked samples was excellent with 94% of the CV (coefficient of variation) values ≤10% among three independent laboratories. Good correlation with the predicate method was demonstrated with correlation coefficients of 0.90 or better with patient samples and 0.99 with spiked samples. The Fungitell STAT index assay provides a rapid and suitable method for serum BDG testing.
