Iowa Oral Performance Instrument (IOPI) is an instrument used to measure tongue strength. The standard protocol of operating IOPI is three trials separated by 10-15 seconds of rest. The highest pressure of these three trials is recorded as the tongue strength. The purpose of this study was to investigate the difference of three trials. Forty-one healthy adults were taken as research subjects. Repeated-measurements analysis of covariance (RANCOVAs) was used to analyze the anterior and posterior tongue strength under four conditions: maximum isometric pressure, dry swallowing, 5c.c. and 10c.c. of water swallowing. The results showed that there were no statistically significant differences among three trials of anterior and posterior tongue strength. It is suggested that before measuring the tongue strength, the participants should be provided with the opportunity to practice, and one or two trials in formal measurements can be adopted to reduce their fatigue.

<b><i>Background:</i></b> The lips and tongue play a substantial role in efficient clearance of food from the mouth and pharynx into the esophagus. No study has compared oral pressures between healthy individuals and poststoke individuals who report functional swallow abilities. <b><i>Aim:</i></b> The current study aimed to investigate the presence of differences in oral pressures between healthy individuals and poststroke individuals who report functional swallowing abilities. <b><i>Design:</i></b> This is a controlled matched pair study. <b><i>Population:</i></b> Eighteen control participants (CG) and 18 nondysphagic poststroke participants (NDSG) were enrolled into this study. <b><i>Methods:</i></b> The Iowa Oral Performance Instrument (IOPI) was used to measure and compare tongue strength, endurance, and functional lingual and labial pressures between sex and age-matched pairs. <b><i>Results:</i></b> Six paired, two-tailed <i>t</i> tests revealed that tongue and lip pressures were different between the 2 groups. Maximum anterior tongue pressures and posterior tongue pressures were also different, i.e., <i>t</i>(17) = –2.89 (<i>p</i> = 0.010) and <i>t</i>(17) = –2.85 (<i>p</i> = 0.011), with the CG presenting higher pressures. Right lip pressures were significantly lower in the NDSG compared to the CG, i.e., <i>t</i>(17) = 2.45 (<i>p</i> = 0.0001). Left lip pressures were significantly lower in the NDSG compared to the CG, i.e., <i>t</i>(17) = –5.43 (<i>p</i> = 0.0001). Tongue endurance, i.e., <i>t</i>(17) = 0.092 (<i>p</i> = 0.928) and saliva swallow pressures, i.e., <i>t</i>(17) = –0.490 (<i>p</i> = 0.63) were not different. <b><i>Conclusion:</i></b> Although poststroke participants reported functional swallowing abilities, there were differences in tongue and lip pressures but not in endurance or saliva swallow pressures. <b><i>Clinical Rehabilitation Impact:</i></b> Poststroke individuals without complaints of dysphagia who are not assessed may experience subclinical dysphagia that could negatively impact their nutrition and quality of life.

This study collected 11 parameters regarding the labial and lingual strength for maximum isometric and swallowing tasks among 150 healthy Chinese adults in Taiwan. Measurements were performed using the Iowa Oral Performance Instrument (IOPI). All of the labial and lingual strength parameters were measured three times. The maximal value of three trials represents the pressure of every parameter. The overall mean (±standard deviation) and maximum isometric pressures of the lips, anterior tongue, and posterior tongue were 24.81 ± 5.64, 55.95 ± 14.13, and 53.23 ± 12.24 kPa, respectively. The mean value of posterior tongue strength was less than that of the anterior tongue by approximately 5%. The percentages of maximum isometric tongue pressure during the swallowing of saliva and water were 85% and 80% for the anterior tongue and 90% and 81% for the posterior tongue, respectively. The average endurances for the anterior tongue and posterior tongue were 13.86 ± 7.08 and 10.06 ± 5.40 s, respectively. The maximum isometric pressures were greater than both the saliva and water swallowing pressures, and the saliva swallowing pressures were greater than the water swallowing pressures. A value of 33 kPa in maximum isometric pressure could serve as a demarcation of weak tongue strength for healthy Chinese adults. As for the repeated trials of labial and lingual strength, there were no statistically significant differences for any of the pressures obtained from the 11 labial and lingual strength parameters. The normative data can be used for the objective assessment of labial and lingual strength in healthy Chinese adults.

SummaryIn 4 collaborative trials, involving a varying number of hospital laboratories in the Stockholm area, the coagulation activity of different test materials was estimated with the one-stage prothrombin tests routinely used in the laboratories, viz. Normotest, Simplastin-A and Thrombotest. The test materials included different batches of a lyophilized reference plasma, deep-frozen specimens of diluted and undiluted normal plasmas, and fresh and deep-frozen specimens from patients on long-term oral anticoagulant therapy.Although a close relationship was found between different methods, Simplastin-A gave consistently lower values than Normotest, the difference being proportional to the estimated activity. The discrepancy was of about the same magnitude on all the test materials, and was probably due to a divergence between the manufacturers’ procedures used to set “normal percentage activity”, as well as to a varying ratio of measured activity to plasma concentration. The extent of discrepancy may vary with the batch-to-batch variation of thromboplastin reagents.The close agreement between results obtained on different test materials suggests that the investigated reference plasma could be used to calibrate the examined thromboplastin reagents, and to compare the degree of hypocoagulability estimated by the examined PIVKA-insensitive thromboplastin reagents.The assigned coagulation activity of different batches of the reference plasma agreed closely with experimentally obtained values. The stability of supplied batches was satisfactory as judged from the reproducibility of repeated measurements. The variability of test procedures was approximately the same on different test materials.

Though there are exhaustive data about participation, performance trends, and sex differences in performance in different running disciplines and races, no study has analyzed these trends in stair climbing and tower running. The aim of the present study was therefore to investigate these trends in tower running. The data, consisting of 28,203 observations from 24,007 climbers between 2014 and 2019, were analyzed. The effects of sex and age, together with the tower characteristics (i.e., stairs and floors), were examined through a multivariable statistical model with random effects on intercept, at climber’s level, accounting for repeated measurements. Men were faster than women in each age group (p < 0.001 for ages ≤69 years, p = 0.003 for ages > 69 years), and the difference in performance stayed around 0.20 km/h, with a minimum of 0.17 at the oldest age. However, women were able to outperform men in specific situations: (i) in smaller buildings (<600 stairs), for ages between 30 and 59 years and >69 years; (ii) in higher buildings (>2200 stairs), for age groups <20 years and 60–69 years; and (iii) in buildings with 1600–2200 stairs, for ages >69 years. In summary, men were faster than women in this specific running discipline; however, women were able to outperform men in very specific situations (i.e., specific age groups and specific numbers of stairs).

Objective To analyze endocan-1, a biomarker of vascular endothelial related pathologies, and the placental growth factor (PlGF), an angiogenic factor and a placental dysfunction marker in patients with preeclampsia (PE). Methods Case-control study conducted at Hospital São Lucas, in the city of Porto Alegre, Brazil. Endocan-1 and PlGF levels were quantified in the maternal plasma using the MagPlexTH-C microsphere system (MAGPIX System, Luminex, Austin, Texas, US) and evaluated through analysis of covariance (ANCOVA) and adjusted by body mass index (BMI), gestational age and maternal age. To estimate the difference between the groups, the mean ratio (MR) and the 95% confidence interval (95%CI) were calculated. The Pearson correlation test was used to establish any association between endocan-1 and PlGF levels. The null hypothesis was rejected when p < 0.05. Results The group of patients was composed by normotensive (n = 67) patients and patients with PE (n = 50). A negative correlation between endocan-1 and the PlGF was noted in the entire normotensive group (linear correlation coefficient [r] = −0.605; p < 0.001), as well as in the PE group (r = −0.545; p < 0.001). Conclusion Endocan-1 levels are increased in patients with PE, and are inversely correlated with PlGF levels. We suggest that it is important to analyze angiogenic and proinflammatory molecules concomitantly in women with PE to better understand the pathophysiology of the disease. Both molecules are strong candidates for PE biomarkers, and future studies will examine any mechanisms connecting these factors in PE.

Objective: To explore the curative effect of Carisolv, a minimally invasive caries removal technique and traditional mechanical caries removal treatment on children's dental caries. Methods: A total of 97 children with dental caries who were treated in the Department of Stomatology in Affiliated Hospital of Chifeng University, Chifeng from September 2017 to May 2019 were selected and recruited as the research subjects. They were divided into two groups by random number table method. Forty-nine individuals were assigned in the control group while the remaining 48 individuals in the observation group. The control group was treated with traditional mechanical caries removal method, and the observation group was treated with minimally invasive caries removal technique, i.e. Carisolv. Both groups were followed up for six months. The degree of pain, recovery time of dental function and complications after six months of treatment were observed in the two groups of children. Results: During the treatment, compared with the control group, the children in the observation group experienced lower degree of pain and had shorter recovery time of dental function. After six months of treatment, the incidence of complications in the observation group was lower than that in the control group. The difference was statistically significant (P<0.05). Conclusion: Compared with traditional mechanical caries removal method, Carisolv, a minimally invasive caries removal technique could reduce the pain of children during the treatment process, shorten the time to restore dental function, reduce the occurrence of complications, and had a better therapeutic effect in treating children’s dental caries.

The Relationship

The output periods of D flip-flop mixer are variable though the periods of two input frequencies are invariable. To measure the output frequency, the conventional method is to calculate the average value of the output periods and the maximum possible absolute error is a clock period. The variation of the output periods has its own pattern of arrangement and it can provide valuable information. Measuring accuracy can be significantly improved by taking into account all the details of output periods changes. A mathematical model that describes the relationship between the input square waves and the output square waves was developed and the difference of two input frequencies can be estimated by the solution of the model. The new method is quite suitable for measuring small frequency increments of quartz crystal resonators.
