Surface and Content Validity of the Mentoring Function Scale for Novice Nurses

This study aimed to examine the surface and content validity of the Mentoring Function Scale for Novice Nurses, used to assess the mentoring of entry-level nurses, and to refine the scale items. In Study 1, six nurse education researchers, selected using convenience sampling, with five or more years of nursing experience and experience teaching novice nurses, were invited to an expert meeting in July 2015. A group interview was conducted that lasted approximately 120 minutes. Study 2 examined the content validity index. Between September and November 2015, we distributed a self-administered questionnaire survey to 11 participants selected by convenience sampling. The participants included five nurse education researchers with a minimum of five years of nursing experience and experience teaching novice nurses, as well as six clinical nurses with a master’s degree or higher. Finally, 81 questionnaire items were retained from the initial 125 items. The 81-item Mentoring Function Scale for Novice Nurses had higher content validity than the original scale. To further increase the scale’s applicability, future studies should assess its reliability, construct validity, and criterion-related validity.

The Effect of TSH Suppression Therapy on the Efficacy and Immune Function of Postoperative Patients with Thyroid Cancer

Objective:To investigate the efficacy and immune function of thyroid stimulating hormone(TSH)suppression therapy in postoperative thyroid cancer patients.Methods:Sixty thyroid cancer patients admitted from July 2020–July 2022 were recruited and randomly divided into two groups.The control group(30 patients)received hormone replacement therapy,while the study group(30 patients)received TSH suppression therapy.The thyroid function,clinical efficacy,immune function,and tumor markers of the two groups were compared.Results:After treatment,the levels of free triiodothyronine(FT3)and thyroxine(FT4)in both groups increased significantly,while TSH levels decreased significantly.Moreover,the magnitude of change in the study group was greater than that in the control group(P<0.05).The total effective rate in the study group was significantly higher as compared to the control group(P<0.05).After treatment,the levels of CD3+and CD4+cells in both groups of patients increased significantly,with the study group showing significantly higher levels than the control group,whereas the level of CD8+cells decreased significantly,with the study group having lower levels than the control group(P<0.05).After treatment,the levels of Tg and CEA in both groups were significantly lowered as compared to before treatment,and the levels of Tg and CEA in the study group were significantly lower than the control group(P<0.05).Conclusion:TSH suppression therapy in postoperative thyroid cancer patients can improve thyroid function,suppress the levels of tumor markers,and enhance immune function,thereby achieving good clinical outcomes.

Analysis of the Energy and Environmental Sustainability of a Built Space System: The Case of Patte d’Oie University Campus in Ouagadougou

The aim of this study was to carry out a dynamic simulation of the energy and environmental performance of a built space system, with a view to assessing its energy and environmental class. The use of a simulation and modeling tool, supported by various methodological references, formed the basis of our approach. Adopting a systemic perspective, we described the structural and functional aspects of the systems making up built spaces, as well as the associated energy flows. Our approach was also based on a typology, taking into account typical days, structural and functional configurations at different scales and angles of observation. The analysis tool we developed in Java was applied to the built space system of the Patte d’Oie university campus in Ouagadougou. Annual electricity consumption was measured at 124387.34 kWh, closely aligned with the average annual electricity bill (125224.31 kWh), with a maximum relative deviation of 1%, followed by a carbon emission balance of 58337.66 kg eq CO2 per year. This validation confirmed the effectiveness of our tool. In addition, following the analysis of electricity consumption using our tool, the university campus was classified in energy class B and environmental class C. These results will be based on the emission factors of the energy mix of the West African Economic and Monetary Union (WAEMU) territory, with particular emphasis on Burkina Faso.

Investigating the Association of Smoking with Thyroid Volume and Function

This study was conducted to explore possible correlation between smoking habit and thyroid volume and function in Jeddah. A total of 226 volunteers i.e. 128 male and 98 female were screened at Radiology Department King Abdul-Aziz University Hospital. They were categorized as smokers and non- smokers;the number of smokers was 99 cases i.e. 48 Cigarette smokers and 51 Shisha smokers, and the non-smokers were 127 cases. The information was gathered via a questionnaire distributed at the radiology department. Ultrasonography of thyroid and thyroid function test were performed for 166 participants;and data were analyzed Using SPSS version 22 and Microsoft excel. The study was carried out based on random selection and findings revealed that most of the cases were in the age group between 20 to 30 years old, high body mass index (BMI) was 33.1 kg/m2 in persons above 60 years old and the highest percentage smokers in the age group from 20 to 30 years (40.02%). Ultrasonography of thyroid showed 96 (58%) normal cases, 46 (28%) abnormal “solid” cases and 24 (14%) abnormal “cyst” cases. A lower proportion of cigarette and shisha smokers (15.4% and 5.6% respectively) had an enlarged thyroid gland compared to no cigarettes or shisha smokers (47.9% and 47.3% respectively). The difference between these frequencies was statistically significant (Chi-square = 9.446 and 11.424, p = 0.002 and p = 0.001 for cigarette and shisha smoking respectively). Consequently, it can be concluded from this research that there are no direct significant values correlating smoking habit to thyroid volume or function. However, it is always recommended not smoke due to other well-known threats.

Objective:To investigate the changing pattern of thyroid and adrenal function in postmenopa-usal women;and the relationship between hormone replacement therapy(HRT)and thyroid andadrenal function.Methods:The levels of tT_3,tT_4,fT_3,fT4,TSH and cortisol were measured in 60 postmeno-pausal women(30 cases in HRT group;30 cases in control group)before and 12 months afterHRT.Results:The serum levels of tT_3,tT_4,fT_3,fT_4,TSH and cortisol had no significant differ-ence before and 12 months after HRT in postmenopausal women.The values of them were all innormal ranges.Conclusion:Changing pattern of thyroid and adrenal function was not as significant as that ofgonads in postmenopausal women and the impact of HRT on it was not so significantly evident.

Study on the relationship of iodine nutritional status with thyroid function and autoantibodies in pregnant women in Baotou

Objective:To investigate the relationship of iodine nutritional status with thyroid function in pregnant women in Baotou,and provide a scientific basis for the guide of reasonable iodine supplementation.Methods:By use of As-Ce catalysis spectrophotometry,the urinary iodine concentration was determined in 90 women during different periods of pregnancy admitted to Baogang Hospital of Inner Mongolia from January 2017 to December 2017.The determination of thyroid function and the autoantibody level was carried out by electro-chemiluminescence immunoassay(ECLIA).Results:In the early trimester of pregnancy,pregnant women with iodine deficiency,iodine sufficiency and iodine excess accounted for 36.67%,40.00%and 23.33%respectively;in the middle trimester of pregnancy,they accounted for 66.67%,26.67%and 6.66%respectively;they made up 40.00%,40.00%and 20.00%respectively in the late trimester of pregnancy.The rate of iodine deficiency in women in the middle trimester of pregnancy was significantly higher than that in women in the early and the late trimesters of pregnancy respectively,and the difference was statistically significant(p<0.05).The rate of iodine deficiency in pregnant women was positively correlated to the positivity of thyroid peroxidase antibody.Moreover,it had no relationship with the positivity of thyroglobulin antibody.No matter in the pregnant women with iodine deficiency or with iodine excess,the abnormality rate of thyroid function and autoantibodies was significantly higher than that in the pregnant women with iodine sufficiency.The difference was statistically significant(p<0.05).Conclusions:The iodine deficiency in the women in the middle trimester of pregnancy is more severe than that in the women in the early and the late trimesters of pregnancy.Iodine deficiency during pregnancy is positively correlated with the positivity of thyroid peroxidase antibody.Pregnant women with iodine deficiency and iodine excess show a higher abnormality rate of thyroid function and autoantibodies.It is recommended to advocate health education on iodine nutrition to pregnant women,and conduct the dynamic monitoring of urinary iodine concentration and the screening of thyroid function and autoantibodies during pregnancy.

Prognostic value of cortisol and thyroid function tests in poisoned patients admitted to toxicology ICU

BACKGROUND: Prognostic value of cortisol and thyroid function tests(TFTs) has previously been evaluated in medical ICUs. We aimed to evaluate prognostic efficacy of cortisol and TFTs in critically ill poisoned patients admitted to toxicology intensive care unit(ICU).METHODS: In a prospective study of consecutively enrolled subjects admitted to the toxicology ICU, lab analyses included TFTs(total T3 and T4 as well as TSH) and cortisol levels drawn between 8 am–10 am during period of the first 24 hours post-ingestion/exposure. Simplified Acute Physiology Score Ⅱ(SAPS Ⅱ) and Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ) were recorded. All scores were compared to detect the best prognostic factor. Type of poisoning was also included.RESULTS: In 200 patients evaluated, 129 were male and mean age was 31 years. In general, SAPS Ⅱ, T4, and cortisol could prognosticate death. After regression analysis, only cortisol had such efficacy(P=0.04; OR=1.06; 95%CI=1.05–1.08; cut-off=42 μg/d L; sensitivity=70%; specificity=82%). Between aluminium phosphide(ALP)-and non ALP-poisoned patients, level of consciousness, mean arterial pressure, and cortisol level could prognosticate death in ALP poisoning(all Ps<0.001 in both uni and multivariate analyses). Median(interquartile range; IQR) GCS was 7(6, 10) and 15(8, 15) in non-ALP and ALP-poisoned patients(P<0.003). SAPS Ⅱ and APACHE Ⅱ could not prognosticate death at all.CONCLUSION: Cortisol best prognosticated outcomes for subjects admitted to the toxicology ICU. Its level is higher in ALP-poisoned patients probably due to the higher stress while they remain conscious till the final stages of toxicity and are aware of deterioration of their clinical condition or may be due to their significantly lower blood pressures.

Effects of High Fluoride and Low Iodine on Thyroid Function in Offspring Rats

Thirty-two Wistar rats were divided randomly into four groups of eight with six females and two males in each group. The rats were exposed to high fluoride drinking water （45 mg F-L^-1 from 100 mg NaF L-1）, low dietary iodine （0.0855 mg kg-1）, or both together in order to assess the effects of these three regimens on the thyroid function of the offspring rats. After the animal model was established, the offspring rats were bred and 10-, 20-, 30-, 60-, and 90-d-old rats were used for the experiment. The treatments for the offspring rats were the same as those of their parents. In comparison with control rats, the relative thyroid glands were changed by three regimens, but the mean values of thyroid weight in the experimental groups saw no marked difference. Serum TT3 levels were increased in all stages in the low iodine （LI） group. In the high fluoride （HiF） group, increase in TT3 levels was observed except in 20-d-old rats. Decrease in TT3 at 20- and 90-d and increase in TT3 at 30- and 60-d were found in HiF＋LI group. Serum TT4 levels first saw an increase, and then dropped in the LI and HiF＋LI group. However, an increase in TT4 was found in the HiF group. The levels of TSH in serum rocketed at d 20, and then dropped in the next stages in experimental groups. The results suggested that thyroid disorder could be induced by high flroride in drinking water, low iodine diet, or both of them. Exposure time to fluoride or low iodine diet was one of the important factors that fluoride can induce the development of thyroid dyfunction.

Relationship between Whole Body Iodine-131 Effective Half-Life and Estimated Glomerular Filtration Rate for Papillary Thyroid Cancer Patients Undergoing Radioactive Iodine Therapy

Background: The aim of this work was to examine the relationship between the estimated glomerular filtration rate (eGFR) as indicator of renal efficiency potentially related to the ability to release radioactive iodine from the patients bodies and the radioactive iodine whole body effective half-life (WBEHL) defined as the time taken for the administered activity to decay to half of its value for papillary thyroid cancer (PTC) patients undergoing radioactive iodine therapy (RAIT) in a tertiary care medical Centre. Methods: This retrospective observational study included seventy nine patients, sixty females and nineteen males. The patients were divided in two subgroups, those who have WBEHL of less than 11 hours (n = 51) and those with more than 11 (n = 28) hrs based on k-means clustering technique. Results: Analysis of variance (ANOVA) was used to find out if there is a statistically significant difference between the two subgroups Conclusion: There was not a statistically significant difference between the short and the longer WBEHL patients’ groups analyzed in this study. .

Impact of Nonlethal Levels of Metacid-50 and Carbaryl on Thyroid Function and Cholinergic System of Channa punctatus

With regard to brain acetylcholinesterase and acetylcholine and serum triiodothyronine(T_3) and thyroxine(T_4)profiles,a biphasic response pattern was elicited in Channa punctatus chroni- cally exposed to nonlethal doses of locally used pesticides,namely,Metacid-50 and Carbaryl. Data revealed that these xenobiotics caused significant inhibition of brain acetylcholinesterase activity and a decrease in thyroxine level accompanied by a concurrent increase in acetylcholine accumulation and T_3 level.It is surmised that Metacid-50 and Carbaryl influence both neural and hormonal functions.1989 Academic Press.Inc.

Molecular Characterization of Thyroid Hormone Receptors (TRs) and their Responsiveness to T3 in Microhylafissipes

To explore and enrich the molecular mechanisms of thyroid hormone receptors （TRs） in the metamorphosis of amphibians, the cDNA sequences of TRa and TRβ in Microhyla fissipes were cloned and characterized. TRa was 1 706 bp in length with an open reading frame （ORF） of 1 257 bp encoding a predicted protein of 418 amino acids and TRβ was 1 422 bp with an ORF of 1 122 bp encoding a predicted protein of 373 amino acids. Their protein sequences contained 4 conserved domains of the nuclear receptor superfamily with two highly conserved cysteine-rich zinc fingers in the DNA-binding domain, whereas TRβ was 42 amino acids shorter in its A/B domain than TRot. Highly-conserved sequences and structures indicated their conserved functions during metamorphosis. TRa expression reached peak at 12 h and then decreased from 12 h to 48 h. While dramatically up-regulated TRβ was observed after exposure of T3 within 24 h, and it was down-regulated from 24 h to 48 h. The expression pattern of TRβ is similar to that in the natural metamorphosis. Furthermore, tadpoles treated 24 h also resembled the climax of metamorphosis tadpoles and TRβ expression had higher responsiveness than TRa to T3 in M. fissipes. These results suggest M. fissipes may serve as the model to assay environmental compounds on TH signaling disruption.

Age- and Gender-Specific Changes in Thyroid Size and Thyroid Function Test Values of Euthyroid Subjects

Background: The thyroid status is evaluated by two clinical diagnostic tests which are thyroid ultrasonography and thyroid function tests. The objective of this research is to critically analyze the age and gender based variations of thyroid volume and thyroid hormone levels in the hospital based euthyroid subjects. Methodology: A total of 221 euthyroid subjects aged 1 - 86 years were selected to observe the normal thyroid size by ultrasonography at Department of Radiology and the thyroid function test values (FT3, FT4 and TSH) of 2413 euthyroid subjects aged (Results: The best fitted equations with significant correlation coefficients and p Conclusion: The thyroid size first increases and then decreases whereas the thyroxin level first decreases and then increases with aging. Left lobe volume is almost same for both genders and right lobe volume is higher in males. The thyroid size in menarche and menopause periods of females is larger than that of males. Such age- and gender-specific changes recommend the new refer-ence ranges for the normal thyroid functions.

Peripheral blood NKT cell number and function in patients with Graves disease and their correlation with hyperthyroidism

Objective:To assess the peripheral blood NKT cell number and function in patients with Graves disease and study their correlation with hyperthyroidism.Methods: The patients who were diagnosed with Graves disease in our hospital between May 2014 and September 2016 were selected as GD group, and 55 healthy volunteers who received physical examination in our hospital during the same period were selected as control group. Peripheral blood was collected to determine the number of CD3+CD56+NKT cells, and serum was collected to detect the contents of cytokines and thyroid function indexes.Results: Peripheral blood CD3+CD56+NKT cell number in Graves disease group was significantly lower than that in control group;serum IL-2, IFN-γ, TNF-α, IL-10 and TGF-β contents in GD group were significantly lower than those in control group and positively correlated with peripheral blood CD3+CD56+NKT cell number while IL-4, IL-5, IL-17, FT3, FT4, TPOAb, TgAb and TRAb contents were significantly higher than those in control group and negatively correlated with peripheral blood CD3+CD56+NKT cell number.Conclusion:The abnormal reduction of peripheral blood NKT cell number in patients with Graves disease can affect the balance of Th1/Th2 and Th17/Treg and increase the TRAb secretion to cause hyperthyroidism.

TSH RECEPTOR GENETIC ALTERATIONS IN THE AUTONOMOUSLY FUNCTIONING THYROID ADENOMAS

Objective To determine the relationship between TSH receptor gene mutations and autonomously functioning thyroid adenomas (AFTAs). Methods The thyroid samples from 14 cases of diagnosed AFTAs were analyzed, with normal thyroid specimens adjacent to the tumors as controls. The 155 base pairs DNA fragments which encompassed the third cytoplasmic loop and the sixth transmembrane segments in the TSH receptor gene exon 10 were amplified by Polymerase chain reaction (PCR) and analyzed by the single-strand conformation polymorphism (SSCP). Direct sequencing of the PCR products was performed with Prism Dye Terminator Cycle Sequencing Core Kit. Results 6 of 14 AFTA specimens displayed abnormal migration in SSCP analysis. In sequence analysis of 3 abnormally migrated samples, one base substitution at nucleotide 1957 (A to C) and two same insertion mutations of one adenosine nucleotide between nucleotide 1972 and 1973 were identified. No mutations were found in controls. Conclusion This study confirmed the presence of TSH receptor gene mutations in AFTAs; both one-point substitution mutation and one-base insertion mutation were found to be responsible for the pathogenesis of AFTAs.

Effect of Occupational Extremely Low-Frequency Electromagnetic Field Exposure on the Thyroid Gland of Workers:A Prospective Study

Objective:The aim of this study was to investigate the biological effects of occupational extremely low-frequency electromagnetic field(ELF-EMF)exposure on the thyroid gland.Methods:We conducted a prospective analysis of 85 workers(exposure group)exposed to an ELF-EMF(100μT,10-100 Hz)produced by the electromagnetic aircraft launch system and followed up on thyroid function indices,immunological indices,and color Doppler images for 3 years.Additionally,116 healthy volunteers were randomly selected as controls(control group),the thyroid function of whom was compared to the exposure group.Results:No significant difference was observed in thyroid function between the exposure and control groups.During the follow-up of the exposure group,the serum free triiodothyronine(FT3)level was found to slowly decrease and free thyroxine(FT4)level slowly increase with increasing exposure time.However,no significant difference was found in thyroid-stimulating hormone(TSH)over the three years,and no significant difference was observed in the FT3,FT4 and TSH levels between different exposure subgroups.Furthermore,no significant changes were observed in thyroid autoantibody levels and ultrasound images between subgroups or over time.Conclusion:Long-term exposure to ELF-EMF may promote thyroid secretion of T4 and inhibit deiodination of T4 to T3.ELF-EMF has no significant effect on thyroid immune function and morphology.

Thyroid function profile, and its association to consumption of cassava and <i>Moringa stenopetala</i>in pregnant women

Background: Pregnancy is associated with the change in thyroid function. Thyroid function is also affected by goitrogenic substances in some plant foods, like cassava. Aim: This study aims to assess thyroid function status and its association to consumption of foods containing goitrogenic substances. Methods: A cross sectional study was done on a total of 65 pregnant women attending Sawla Health Center, South Ethiopia. Serum samples were collected and analyzed for TSH, total T4 and total T3 by using ELISA kit. Data on consumption of foods containing were obtained from food frequency questionnaire. Results: The median TSH of the first, second and third trimesters, respectively are 2.57, 1.86 and 2.42 mIU/L, which are within the reference interval (0.30-6.20 mIU/L) of the test kit. The median total T4 values (9.8, 10.0 and 10.3 μg/dl in the first, second and third trimesters, respectively) were also within the reference interval (4.8-11.6 μg/dl) of the test kits. The median total T3 in the first (2.60 ng/ml) and third (2.35 ng/ml) trimesters were elevated, but it was within the reference interval (0.69-2.02 ng/ml) in the second trimester (1.92 ng/ml). Though statistically non-significant median TSH was increased in women grouped as cassava consumers and M. stenopetala consumers while median total T4 values were decreased in these groups. Conclusion: The study subjects have normal thyroid function as the median values of TSH and total T4 were within the reference interval of the test kit. Frequent consumption of cassava and Moringa stenopetala may affect thyroid function.

Effects of selenium supplementation on thyroid function, immune response and oxidative stress in HT patients

Objective:To explore the effect of selenium supplementation on thyroid function, immune response and oxidative stress in HT patients with normal thyroid function.Methods: A total of 120 Hashimoto's thyroiditis patients with normal thyroid function admitted to our hospital from June 2016 to March 2018 were randomly divided into treatment group and control group with 60 cases in each group. The control group was given oral placebo, while the treatment group was given selenium yeast. The expression levels of thyroid function [including thyroid stimulating hormone (TSH), free triiodothyronine (FT3) and free thyroxine (FT4)], immune response [including thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TGAb), interferon-γ (IFN-γ), interleukin-4 (IL-4)] and oxidative stress [including malondialdehyde (MDA), glutathione peroxidase (GPx) and superoxide dismutase (SOD)] were observed and compared between the two groups.Results: The two groups showed significant changes in auxiliary diagnosis, immune response and oxidative stress. Before treatment, there was no significant difference in the levels between the two groups. After treatment, there was no significant difference in the above indexes between the control group and that before treatment. There was no significant difference in thyroid function related indexes between the treatment group and the control group. The levels of TPOAb, TGAb, IFN-γ and MDA in the treatment group were significantly lower than those before treatment and in the control group, while the levels of IL-4, GPx and SOD were significantly higher than those before treatment and in the control group.Conclusions: Selenium supplementation can stabilize thyroid function, reduce the level of thyroid antibody production, and improve immune response and oxidative stress response in HT patients.
