The Difference

To compare the fetal cerebellum and cisterna magna length measurements by means of two- (2DUS) and three-dimensional (3DUS) ultrasonography using the three-dimensional extended imaging (3D XI), a cross-sectional study with 69 healthy pregnant women between 18 and 24 weeks was performed. For the measurements by 2DUS, the axial planes were used and for the 3DUS a sequence of adjacent axial slices (multislice view). To evaluate the difference between the two techniques, we used the Wilcoxon test. To evaluate the correlation between the cerebellum and cisterna magna length measurements and the gestational age, we used the Spearman correlation coefficient (r). For the calculation of reproducibility, we used the intraclass correlation coefficient (ICC). The mean of the transverse and anterior-posterior diameter of cerebellum and cisterna magna by 3DUS was 9.23 and 6.62 mm, respectively. It was observed that the average of the measurements obtained by 3DUS was significantly higher, 0.76 and 1.02 mm for the length of the cerebellum and cisterna magna, respectively (P<0.001). There was a high correlation between the length measurement of the cerebellum 3D (r=0.940, P<0.001), but low correlation of cisterna magna 3D (r=0.462, P=0.080) with the gestational age. There was good intra- and interobserver reproducibility for the cerebellum and cisterna magna 3D with ICC=0.792 , 0.668, 0.691, and 0.287, respectively. The measurements of the fetal cerebellum and cisterna magna length by 3DUS using the software 3D XI were significantly higher than those obtained by 2DUS.

Purpose: Purpose of this study is to evaluate the measuring consistency of central refraction between multispectral refraction topography (MRT) and autorefractometry.Methods: This was a descriptive cross-sectional study including subjects in Sun Yat-sen Memorial Hospital from September 1, 2020, to December 31, 2020, ages 20 to 35 years with a best corrected visual acuity of 20/20 or better. All patients underwent cycloplegia, and the refractive status was estimated with autorefractometer, experienced optometrist and MRT. We analyzed the central refraction of the autorefractometer and MRT. The repeatability and reproducibility of values measured using both devices were evaluated using intraclass correlation coefficients (ICCs).Results: A total of 145 subjects ages 20 to 35 (290 eyes) were enrolled. The mean central refraction of the autorefractometer was −4.69 ± 2.64 diopters (D) (range −9.50 to +4.75 D), while the mean central refraction of MRT was −4.49 ± 2.61 diopters (D) (range −8.79 to +5.02 D). Pearson correlation analysis revealed a high correlation between the two devices. The intraclass correlation coefficient (ICC) also showed high agreement. The intrarater and interrater ICC values of central refraction were more than 0.90 in both devices and conditions. At the same time, the mean central refraction of experienced optometrist was −4.74 ± 2.66 diopters (D) (range −9.50 to +4.75D). The intra-class correlation coefficient of central refraction measured by MRT and subjective refraction was 0.939.Conclusions: Results revealed that autorefractometry, experienced optometrist and MRT show high agreement in measuring central refraction. MRT could provide a potential objective method to assess peripheral refraction.

Category: Trauma; Ankle Introduction/Purpose: Fibular nailing (FN) is a method of fixation that has proven to be useful for the treatment of distal fibular fractures (DF). FN minimizes soft tissue complications, provides similar stability compared to plating with less hardware related symptoms. Nevertheless, FN has been associated with syndesmotic malreduction and incapacity of restoring length and rotation of the fibula. We aimed to evaluate the fibular and syndesmotic reduction after fixation with FN compared to the uninjured ankle. Methods: Prospective cohort, cross-sectional study with a paired control group. Patients with DF fractures treated with FN between January 2017 and July 2019 were included. Immediate postoperative bilateral Ankle CT was obtained in all cases. Two independent radiologists performed all the measurements on both ankles (fibular rotation, length, translation, and syndesmotic diastasis. Statistical analysis was made using the Wilcoxon Test and Intraclass correlation coefficient (ICC). Considering a medium size sample effect, 95% confidence with .05 alpha error, a total sample of 26 subjects were needed to achieve a .80 of statistical power (G-Power 3.1). All analyses were performed using SPSS V20. Results: Twenty-six patients were included (14 Women). The mean age was 47 years (18-91). No statistically significant differences were identified considering fibular rotation (p:0,694), fibular length (p:0,585) and syndesmotic diastasis (p:0,078) between the injured and uninjured ankle. Fibular translation has statistical differences (p:0,043). The ICC shows an excellent concordance between radiologists except for Fibular translation (ICC 0,47) Conclusion: In this cohort, fixation of DF fractures with FN allows restoration of anatomical parameters of the ankle in terms of fibular rotation, length, and syndesmotic diastasis. However, Fibular translation had significant differences compared with the uninjured ankle.

ABSTRACT Objective: to analyze the consistency of responses of evaluators and to verify the usability of the perception and analysis of SOLAR (Science of Language and Reading) Methods: a non-experimental descriptive cross-sectional study. Elementary school teachers and undergraduate students of speech therapy and pedagogy participated as the judges. The judges used the SOLAR Scale as an instrument to analyze the reading fluency of twenty audios recorded by elementary school students. Usability comparisons were performed using the Kruskal Wallis test and two-by-two comparisons using the Mann Whitney test. To analyze the consistency of the responses between the judges, the calculation of the interclass correlation coefficient was used. Results: the analysis of the reliability of the answers showed an excellent intraclass correlation coefficient for all the skills of the Scale. As for the usability of the Scale, more than 80% of the participants positively evaluated the assessment. This was verified through the usability questionnaires which confirmed that it was easy to use, with clear guidelines and that users felt comfortable and confident using it. Conclusion: SOLAR obtained good results in reliability and consistency with excellent agreement between the evaluators. These results indicated satisfactory reliability of the SOLAR items and favorable qualitative ratings from users.

Helminths infection is one of the diseases that still occur insociety. The helminth infection caused by theSoil-Transmitted Helminths (STHs) group, which is Ascaris lumbricoides, Trichuris trichiura, and hookworm in human cancause chronic bleeding resulting in decreasir on storage in the body and increased level of hepcidin. Hepcidin is a liverhormone which regulates iron metabolism and can function as marker of inflammation and iron deficiency. This study aimedto compare the hepcidin levels in STH-infected and non-infected children. A cross-sectional study was conducted betweenMay and October 2018 on 28 STH infected and 140 non-infected subjects. The collected stool samples were analyzed usingthe Kato-Katz method to determine the presence of STH infection and the degree of infection. Urine samples wereprocessed, and their hepcidin levels were measured using a Sandwich-ELISA method. Measurement was made using aSpectrophotometer. The difference of numeric variables was analyzed using Wilcoxon test. The prevalence of STH infectionwas 16.66%. The prevalence of Trichuris trichiura 10.71%, Ascaris lumbricoides 4.76% and hookworm 2.97%. The prevalenceof a single infection was 14.88% and mixed infection 1.78%. Based on the intensity of infection, 15.48% of subjects were mildinfection, 0.59% moderate infection, and 0.59% severe infection. Hepcidin levels in the infected and uninfected group didnot differ significantly (p=0.978). There were no different hepcidin levels in children with and without soil-transmittedhelminths infection.

Objective To externally validate the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) formula developed from the National Fetal Growth Studies-Singletons and compare with 1984 Hadlock regression in a general obstetrical population. Study Design Cross-sectional study of nonanomalous singletons with a crown-rump length (CRL) and ≥1 additional ultrasound (US) with complete fetal biometrics. CRL established the referent estimated due date to calculate the error at every examination from both formulas. Error was the difference between the CRL-derived gestational age (GA) and each method's predicted GA. Comparisons were also made in three GA intervals: 1 (140/7–206/7), 2 (210/7–286/7), and 3 (≥290/7). Odds ratios evaluated the likelihood of errors outside the prespecified (±) day ranges. Repeated measures analysis of variance and generalized estimating equations controlled multiple US in the same patient. Results A total of 6,043 patients produced 16,904 USs for evaluation. The NICHD formula yielded significantly smaller mean errors in all GA ranges compared with the Hadlock formula (p < 0.01). In interval 3, the NICHD formula had significantly lower odds of discerning examinations outside the prespecified error range (odds ratio: 1.27). Conclusion The NICHD formula is a valid estimate of estimating GA in a general obstetrical population and was superior to the Hadlock formula, most notably in the third trimester.

Background: Disinfection procedures are an essential aspect of preventing cross contamination, especially in situations where the risk of infection is higher, such as in operating rooms (ORs). Disinfection procedures in ORs at the end of each surgery session are not the same as final cleaning procedures. We assessed the difference in microbial contamination between different levels of disinfection, before T(0) and after T(1) the use of an ultraviolet C device (UVC-D). Methods: A cross-sectional study was conducted between December 2019 and August 2020 in a private clinic. Three sanitation levels (SL1–SL3) were compared for the reduction in colony-forming units (CFU) between T(0) and T(1): (1) no disinfection after surgery (SL1);, (2) after in-between cleaning (SL2), and (3) after terminal cleaning (SL3). UVC-D was used for 6 minutes, 3 minutes per bed side. Overall, 260 Petri dishes were used in 3 ORs, incubated at 36°C, and CFU were counted after 48 hours. Descriptive statistics, Wilcoxon test, and MANOVA for repeated measures were performed to verify the 95% statistical difference between T(0) and T(1), both on the whole sample and combined with the different SLs. Results: The unstratified analysis showed statistically significant differences (Wilcoxon test, p < 0.05) between T(0) and T(1), with means and standard deviations of 11.42 ± SD 41.19 CFU/PD and 5.91 ± SD 30.89, respectively. The Manova test for repeated measures, applied to 54 pairs of measurements, showed no significant difference between SLs in T(0)-T(1) CFU reduction. Overall, the mean percent reduction in CFU was 93.48% (CI95% = 86.97-99.99%). Conclusions: The results showed significant improvements in disinfection under any condition tested with UVC-D. Using the device immediately after surgery (SL1), before standard cleaning procedures, reduced CFUs by 97.3%. In some situations, UVC light was sufficient to reduce CFU to zero, even without chemical and mechanical cleaning. However, we do not recommend this approach; UVC light disinfection should be applied only after sanitization procedures because it does not remove dirt.Funding: UltraViolet Device, IncDisclosures: None

Objective: To determine the difference of glutathione peroxidase (GPx) in threatened miscarriages and normal pregnancy. Method: This is an analytic cross sectional study with 42 samples divided into two groups. Group 1 consists of 21 cases of threatened miscarriages with < 20 gestational age and group 2 is divided into 21 normal pregnancies of < 20 weeks gestational age. We took 3 cc of blood samples from the cubiti veins and mixed it with EDTA. Its GPx quantities were than examined at the Pathology Lab at Sanglah General Hospital. Data was then analyzed using the Shapiro Wilk Test and the independent t-test with p < 0.05. Result: From this research, we obtained the mean GPx levels on the threatened miscarriages was 49.92 ± 14.17 U/g Hb lower than the mean of normal pregnancy levels, which was 88.94 ± 30.11 U/g Hb. Conclusion: The quantities of GPx between threatened miscarriages and normal pregnancies are statistically different, in which the quantity of GPx in threatened miscarriages is lower compared to normal pregnancy.

Nurse Prescribing

Low self-efficacy is a barrier to effective nurse prescribing. Therefore, nurses’ self-efficacy should be assessed using validated tools. We aimed to develop and psychometrically test the Nurse Prescribing Self-Efficacy Scale (NP-SES). We conducted an observational cross-sectional study with 290 nurses between January and June 2019. We studied the NP-SES’ reliability (i.e., internal consistency and temporal stability), validity (i.e., content, criterion, and construct) and legibility. The NP-SES showed good internal consistency (Cronbach’s alpha=0.958) and temporal stability (intraclass correlation coefficient=0.783). The NP-SES also showed good content validity (scale’s content validity index=0.98) and criterion validity ( r=0.75; p<0.001). Construct validity analysis revealed the NP-SES’ three-dimensional structure and showed its ability to detect significant differences between nurses with different levels of experience. Our psychometric analysis suggests that the NP-SES is a reliable and valid instrument that could be used to assess nurses’ self-efficacy in nurse prescribing.

Purpose: Anatomical sacral slope (a-SS), a pelvic anatomical parameter that does not require the center of the femoral head, strongly correlates with pelvic incidence (PI) during three-dimensional measurements in normal subjects. Sagittal alignment of spinal and pelvic parameters is typically evaluated using two-dimensional radiographs; however, the relationship between a-SS and PI has not been evaluated using radiographs. This study aimed to evaluate the correlation between a-SS and other spinal and pelvic parameters using radiographs. Methods: We evaluated 144 healthy women. Using sagittal radiographs, we measured lumbar lordosis (LL), thoracic kyphosis, PI, SS, pelvic tilt, and a-SS, which were defined as the angle between the superior end plate of S1 and a line perpendicular to the anterior pelvic plane. Pearson coefficients were used to determine correlations, and intraobserver and interobserver intraclass correlation coefficients (ICCs) were used for validation. Results: There was a strong correlation between PI and a-SS ( r = 0.756). Moreover, correlations between a-SS and LL and between PI and LL were similar ( r = 0.661 and r = 0.554, respectively). The intraobserver ICCs were 0.884 for a-SS and 0.840 for PI. The interobserver ICCs were 0.856 for a-SS and 0.653 for PI. Conclusion: a-SS was strongly correlated with PI. The correlation between a-SS and LL was equivalent to the correlation between PI and LL. Moreover, the ICC for a-SS was larger than that of PI. This study suggests that a-SS is a useful new pelvic anatomical parameter that can be used instead of PI.

Thickness Measurements

Purpose. To compare the measurements of fetal nuchal fold (NF) thickness by two-dimensional (2D) and three-dimensional (3D) ultrasonography using the three-dimensional extended imaging (3DXI).Methods. A cross-sectional study was performed with 60 healthy pregnant women with a gestational age between 16 and 20 weeks and 6 days. The 2D-NF measurements were made as the distance from the outer skull bone to the outer skin surface in the transverse axial image in the suboccipital-bregmatic plane of the head. For the 3D we employed the 3DXI multislice view software, in which3×2tomographic planes was displayed on the screen and the distance between the tomographic slices was 0.5 mm. Maximum, minimum, mean, and standard deviation were calculated for 2D and 3D ultrasonography, as well the maximum and minimum, mean, and standard deviation for the difference between both methods. The Wilcoxon signed-rank test was used to compare the two different techniques.Results. 2D-NF showed a mean of thickness of3.52±0.95 mm (1.69–7.14). The mean of 3D-NF was3.90±1.02 mm (2.13–7.72). The mean difference between the methods was 0.38 mm, with a maximum difference of 3.12 mm.Conclusion. The NF thickness measurements obtained by 3D ultrasonography were significantly larger than those detected with 2D ultrasonography.
