Abstract BackgroundThe incidence of thyroid nodules increased significantly, but the mortality rate of thyroid cancer remained stable or even decreased. However, surgical treatment of thyroid nodules is more aggressive, including the number and scope of surgery. the purpose of our study was to evaluate whether unilateral thyroid nodules affect the malignancy risk of contralateral thyroid nodules. Methods We conducted a retrospective study on all patients with thyroid nodules in a tertiary hospital within one year. Unilateral and bilateral thyroid nodules were the control group and the experimental group, respectively. Based on the TI-RADS grades, the experimental group and the control group were divided into two subgroups. We used chi-square test or Fisher's exact test to evaluate whether there were statistical differences in the incidence and pathological types of thyroid cancer between the experimental group and the control group. Results Our study showed that there was no significant difference in malignant risk between the experimental group 1 and the control group 1, and the experimental group 2 and the control group 2 (20%vs35%, p=0.724, 63.16%vs76.32%, p=0.297, respectively). Both the a-side thyroid of the experimental group and the control group were papillary thyroid carcinoma, including micropapillary thyroid carcinoma, and there was no difference in the proportion of micropapillary thyroid carcinoma (p = 0.200, 0.620, respectively). Conclusions There is no evidence that bilateral thyroid nodules affect each other in terms of malignant risk, that is, in bilateral thyroid nodules, unilateral thyroid cancer does not change the malignant risk of contralateral thyroid nodules.This study has been registered with the Chinese Clinical Trial Registry, clinical trial registration number: ChiCTR2000038611, registration time: 2020-09-26.

Excessive hair loss will cause baldness. It can will influence someone’s confidence. that is why, hair loss treatment is needed to be done. One of them is by using avocados and VCO. They have good function to stimulate hair growth and make them healthier. This study aims to analyze the effect of avocados and VCO toward hair loss treatment. The research was done by observing the mount of hair loss everyday. this study was conducted with a quasi-experimental method with a quasi exsperiment to explain the influence of using avocados and VCO on the treatment of hair loss. The research subjects were a collection of women who lived in the Parak Laweh area of ​​Lubuk Begalung subdistrict which improved hair loss at the level of 40-100 strands per day. The sample in this study amounted to 12 people used by the technique of taking documentation and interviews. This study consisted of 4 different groups, namely the control group (X0), experimental group 1 (X1), experimental group 2 (X2), and experimental group 3 (X3).The data gathered is primary data. It is directly taken from samples that fill in the research format provided. Data analysis using analysis of variance (anava) and continued with Duncan test, the results of this study show a significant difference in the indicator of the amount of hair detached from the scalp with the number of strands of hair falling after treatment in the control group (X0) (80.50), experimental group 1 (X1) (60.50), experimental group 2 (X2) (58.83) and experimental group 3 (X3) (58.67). So it can be said that for the indicator of the amount of hair loss in the experimental group did not show a statistically significant difference, but there was a significant difference in the treatment of hair loss in the control group.

Background. Thin soles and resulting lameness in cows are often due to abrasive walking surfaces that cause increased wear. The aim of this project was to compare horn growth and wear and sole thickness in cows kept on rubber mats versus concrete in a free-stall barn. Methods. To examine horn growth and wear and sole thickness, we examined two groups (Group 1 kept on concrete [control] and Group 2 on rubber mats) of 12 cows each at 2-week intervals over a 12-week period. The 12 cows in each group were selected to achieve equal parity in each group, as follows: four cows, parity 1; four cows, parity 2; two cows, parity 3; and two cows, parity 4. The four cows from the parity 1 group had the most days in milk in the herd irrespective of milk production. The remaining eight cows had the fewest days in milk (most recently calved) irrespective of milk production. Results. Cows in the control group had a significant increase in claw horn growth over the study period, compared to the control group. Most of this difference in horn growth occurred during the first 2 weeks of the study. There was no significant difference in claw horn wear and sole thickness at 2 weeks or at the end of the study. There was, however, a non-significant difference in wear between cows in the 2 groups at the end of the study, with cows in the control group showing most wear. Cows in the experimental group exhibited significant increases in all parameters (claw length, wear, and growth; sole thickness) when measured at the beginning and end of the trial, whereas cows in the control group showed a significant increase in claw length and sole thickness.Discussion. These findings suggest that there was a compensatory increase in horn production in response to accelerated claw horn wear in the control group. Statistical significance in wear might have been attained between groups at the end of the study if the study had continued over a longer period.

Background. The incidence of thyroid nodules increases in the general population. Similarly, we have also seen a dramatic increase in the number of thyroid surgeries. However, the mortality rate of thyroid cancer remained stable or even decreased. The purpose of our study was to investigate whether thyroid cancer affects the malignant risk of the contralateral TI-RADS 3 and 4 nodules. Methods. We conducted a retrospective cohort study in our institution for all thyroid procedures due to nodules from December 2018 to December 2019. All eligible patients were divided into the experimental group (bilateral nodules) and the control group (unilateral nodules) to assess whether the proportion of malignant nodules was different between the two groups. Multivariate logistic regression analysis was used to control potential confounding factors to investigate whether their differences were statistically significant. Results. A total of 330 patients underwent thyroid surgery, of whom 137 were eligible, including 84 in the experimental group and 53 in the control group. The proportion of malignant nodules was significantly different between the experimental group and the control group (29.8% versus 58.5%, unadjusted OR 0.30, 95% CI: 0.17–0.82, p = 0.001 ). However, after controlling for potential confounding factors, including age ( p = 0.004 ), gender ( p = 0.775 ), and TI-RADS classification ( p ≤ 0.001 ), we found that the difference was not significant (adjusted OR 1.08, 95% CI: 0.39–3.01, p = 0.886 ). Conclusion. There is no evidence that thyroid cancer affects the malignant risk of the contralateral TI-RADS 3 and 4 nodules. This study has been registered with the Chinese Clinical Trial Registry (clinical trial registration number: ChiCTR2000038611, registration time: September 26, 2020).

Aim: The aim of this study is to use storytelling as a technique to develop entrepreneurial intention in Islamic boarding school graduates. Background: Most of the pesantren graduates in Indonesia do not proceed on to university studies after completing their schooling due to financial problems and so lack the skills to work on jobs that could support their livelihood. Therefore, pesantren wanted to develop a strategy to help its alumni find employment after completing their education. Increasing the entrepreneurial intention of graduates in various sectors is one way in which pesantren expect to support graduates in finding their livelihood. Objective: The objective of this study is to test the effectiveness of storytelling in increasing entrepreneurial intentions in students. Methods: Sixty Islamic boarding school students participated in this study. The Solomon three-group design was used to test the effectiveness of storytelling in increasing the entrepreneurial intentions of students. Participants were divided into three groups: the experimental group, control group 1, and control group 2, each consisting of 20 students. The entrepreneurial-intention scale was used to measure the level of entrepreneurial intention among each group of students. Results First, there was a significant difference between the post-test score of entrepreneurial intention in the experimental group (with treatment) and the post-test score of entrepreneurial intention in control group 1 (without treatment). Second, the post-test score of entrepreneurial intention in the experimental group (with treatment) was not different from the post-test score of entrepreneurial intention in control group 2 (with treatment). Thus, the results were consistent in the sense that the group that received treatment had an increased level of entrepreneurial intention when compared with the group that did not receive any treatment. Conclusion: The results showed that storytelling was effective in increasing the entrepreneurial intention of students. In this study, the treatment of storytelling was integrated with a focus group discussion. Developing treatment with other techniques can have a greater effect on increasing the entrepreneurial intention of students.

Hypnosis is the fastest and most effective way to get into the subconscious mind. Each suggestion was nine times stronger than the usual situation. This experimental research aims to provide a description of the effect of learning accompanied by self-hypnosis on increasing mathematics scores. The test is done by comparing the post-test scores of the control group and the experimental group through the t test for the independent sample. This experimental study concluded that the method of learning mathematics with self-hypnosis was able to improve students' mathematical abilities. This conclusion is evidenced by the significant difference between the mean of group 1 as the control variable and group 2 as the experimental variable after being given treatment or stimulus for a period of 1 semester

ObjectivesThe aim of this study was to establish quantitative values for asymptomatic and symptomatic Achilles tendons.DesignCohort study with a single (cross-sectional) time point of patients diagnosed with unilateral Achilles tendinopathy and an asymptomatic group with comparative homogeneity.MethodsA sample of 50 participants: 25 diagnosed with symptomatic unilateral Achilles tendinopathy (AT group) and 25 with asymptomatic Achilles tendons (control group 2). The asymptomatic side of the AT group was used as a control (control group 1). Measurements at 2 cm intervals on the tendon from its insertion at the calcaneum up to the musculotendinous junction were taken non-weight bearing (NWB) and weight bearing (WB) using the MyotonPRO.ResultsThere was a significant (p<0.005) decrease in natural oscillation frequency (F) at points 2, 3 and 4 of the AT group (NWB condition) and points 2 and 3 for the WB condition. There was a significant (p<0.005) increase in logarithmic decrement (D) at points 2 and 3 signifying a decrease in elasticity. Dynamic stiffness (S) was significantly (p<0.005) reduced in the AT group at points 2 and 3 WB and point 3 WB. There was no significant difference in creep (C) observed between the symptomatic and asymptomatic tendons. There was a significant (p<0.005) increase in mechanical stress relaxation time (R) at point 2 NWB.There was a correlation between body weight and gender on tendon mechanics, with the symptomatic tendons. No significant differences were observed between the control group 1 and control group 2.ConclusionsThe MyotonPRO measured decreased stiffness over a section of the tendon corresponding clinically with Achilles tendinopathy. This may have potential in identifying risk of injury and informing rehabilitation, however further extensive research is required to generate baseline data for specific population groups monitoring variables over time. Age, gender and body mass index appear to have some bearing on the mechanical properties of the tendon but mainly in the tendinopathy group.

The aim of this study was to investigate the frequency of nocturnal sperm emissions (NSE) in varicocele patients after varicocele surgery. A total of 127 patients, 96 varicocele (Group 1) and 31 patients with inguinal hernia (Group 2) were included in this study. Mean age, laterality of surgical procedures, spermiogram results, marital status, and postoperative serum hormone levels were noted for all patients. Two groups were compared in terms of Beck depression score (BDS) and anxiety scores (AS). The frequency of NSE and libido changes in the patients during 10 days postoperatively was evaluated. The number of the patients who had NSE and increased libido were significantly higher in the varicocelectomy group when compared with the control group. No significant difference was noted between the groups in terms of BDS, AS, and serum hormone levels. No association was reported between BDS, AS, and serum hormone levels and the presence of NSE in Group 1. The incidence of NSE was higher in younger men. Increased libido was significantly associated with NSE in Group 1. Cord dissection during surgery may be a factor on increased frequency of NSEs in varicocele patients.
