OBJECTIVE: Subacute thyroiditis(SAT) is an acute inflammatory, self-limited, and destructive disease of the thyroid gland. Although it is a temporary disease, it has permanent consequences. We aim to investigate the influences of the treatment choice on permanent hypothyroidism occurring after SAT and whether there are predictive factors for the development of permanent hypothyroidism. METHODS: We retrospectively investigated 57 SAT patients admitted to our tertiary hospital between 2017 and 2019. After excluding 6 patients, demographic, clinical, laboratory, and imaging findings of 36 patients treated with NSAIDs and 15 patients treated with corticosteroids were compared. The median duration of follow-up was 4 (3.5-5.5) years. RESULTS: Permanent hypothyroidism occurred in 16 patients (31.4%) of 51 patients. It developed at a significantly higher rate in NSAID users (p=0.019). There was no significant difference in the occurrence of transient hypothyroidism and recurrence (p=0.472, p=0.082). The early maximum TSH values were strongly associated with permanent hypothyroidism. The Odds Ratio (OR) value was 2.59 (95% CI = 1.26 - 5.33, p=0.009), Nagelkerke R2 = 0.821. The early maximum TSH level had a predictive value, with an AUC of 0.966 for post-SAT permanent hypothyroidism (p<0.001). The cutoff values for the early maximum TSH were 9.07uIU/ml (81.3% sensitivity, 100% specificity), and 7.05 uIU/ml (87.5% sensitivity, 94.3% specificity). CONCLUSION: Corticosteroid therapy is significantly effective in preventing permanent hypothyroidism from developing after SAT. The early maximum TSH values are an indicator for the prediction of the development of permanent hypothyroidism.

BACKGROUND: Digital health technologies are rapidly evolving and transforming the care of diabetes and cardiovascular disease (CVD). PURPOSE OF THE REVIEW: In this review, we discuss emerging approaches incorporating digital health technologies to improve patient outcomes through a more continuous, accessible, proactive, and patient-centered approach. We discuss various mechanisms of potential benefit ranging from early detection to enhanced physiologic monitoring over time to helping shape important management decisions and engaging patients in their care. Furthermore, we discuss the potential for better individualization of management, which is particularly important in diseases with heterogeneous and complex manifestations, such as diabetes and cardiovascular disease. This narrative review explores ways to leverage digital health technology to better extend the reach of clinicians beyond the physical hospital and clinic spaces to address disparities in the diagnosis, treatment, and prevention of diabetes and cardiovascular disease. CONCLUSION: We are at the early stages of the shift to digital medicine, which holds substantial promise not only to improve patient outcomes but also to lower the costs of care. The review concludes by recognizing the challenges and limitations that need to be addressed for optimal implementation and impact. We present recommendations on how to navigate these challenges as well as goals and opportunities in utilizing digital health technology in the management of diabetes and prevention of adverse cardiovascular outcomes.

BACKGROUND: Phytoestrogens have been praised for their beneficial health effects, whereas synthetic xenoestrogens have been connected to ailments. AIMS: To ascertain whether the toxicities of natural and synthetic estrogens differ, we examined the potent phytoestrogen 8-prenylnaringenin (8-PN), the common synthetic xenoestrogen tartrazine, and the physiological estrogen 17β-estradiol (E2). METHODS: These three compounds were tested for cytotoxicity, cell proliferation and genotoxicity in human HepG2 and rat H4IIE hepatoma cells. RESULTS: All three estrogens elicited cytotoxicity at high concentrations in both cell lines. They also inhibited cell proliferation, with E2 being the most effective. They all tended to increase micronuclei formation. CONCLUSION: Natural estrogens were no less toxic than a synthetic one.

UNLABELLED: Purpose:Osteoporosis is characterized by low bone mineral density (BMD) and high risk of osteoporotic fracture (OF). Peripheral blood monocytes (PBM) can differentiate into osteoclasts to resorb bone. This study was to identify PBM-expressed proteins significant for osteoporosis in Chinese Han elderly population (>65 years), and focused on two phenotypes of osteoporosis: low BMD and OF. METHODS: Label-free quantitative proteomics was employed to profile PBM proteome and to identify differentially expressed proteins (DEPs) between OF (N=27) vs. non-fractured (NF, N=24) subjects and between low BMD (N=12) vs. high BMD (N=12) subjects in women. Western blotting (WB) was conducted to validate differential expression, and ELISA to evaluate translational value for secretory protein of interest. RESULTS: We discovered 59 DEPs with fold change (FC)>1.3 (P<1×10-5), and validated the significant up-regulation of pyruvate kinase isozyme 2 (PKM2) with osteoporosis (P<0.001). PKM2 protein upregulation with OF was replicated with PBM in men (P=0.04). Plasma PKM2 protein level was significantly elevated with OF in an independent sample (N=100, FC=1.68, P=0.01). Pursuant functional assays showed that extracellular PKM2 protein supplement not only promoted monocyte trans-endothelial migration, growth, and osteoclast differentiation (marker gene expression), but also inhibited osteoblast growth, differentiation (ALP gene expression), and activity. CONCLUSION: The above findings suggest that PKM2 protein is a novel osteoporosis-associated functional protein in Chinese Han elderly population. It may serve as a risk biomarker and drug target for osteoporosis.

INTRODUCTION: Organoids are three-dimensional cellular aggregates derived from stem cells or primary tissues that can self-organize into organotypic structures and showcase the physiological functions of that organ. Organoids typically comprise multiple organ-specific cell types that are responsible for organ function in vivo. They may also incorporate various cellular and molecular stromal components to recapitulate the in vivo microenvironment of the target organ. METHODS: All articles related to thyroid-like organs were synthesized. Articles published between 1959 and 2023 were assessed, categorized, and analyzed using relevant keywords. RESULTS: As such, organoids provide a model of greater physiological relevance than 2D cell culture for basic and translational research. Murine and human organoids of the thyroid have been established from embryonic stem cells (ESCs), pluripotent stem cells (PSCs) and from various healthy or diseased thyroid tissues. These thyroid organoids have been used in basic and translation research on thyroid-related diseases including hyperthyroidism, Graves' disease, and Hashimoto's thyroiditis. In addition, organoids derived from patients with thyroid cancer retain histopathological features and mutational profile of the original tumor. These patient-derived organoids have been successfully used in in vitro evaluation of drug response of individual patients, demonstrating their potential application in personalized treatment of thyroid cancer. CONCLUSION: In this review article, we have discussed various techniques for establishing thyroid organoids and their applications in thyroid-related diseases as disease models, regenerative medicines, or a tool for drug testing.

Patients undergoing thyroidectomy often develop hypocalcemia. While there is evidence suggesting that the prophylactic administration of dexamethasone in patients undergoing thyroidectomy can reduce the risk of postoperative complications including nausea, vomiting, and pain, it remains uncertain as to whether such treatment has a similar impact on hypocalcemia risk. Here, randomized controlled trials (RCTs) focused on comparing the risk of postoperative hypocalcemia in thyroidectomy patients that either were or were not administered a single preoperative dose of dexamethasone were systematically evaluated. These RCTs were identified by searching the Medline, PubMed, Embase, and Cochrane Library for all relevant publications as of April 2023. Primary study outcomes included biochemical hypocalcemia and symptomatic hypocalcemia incidence within 24 h after thyroidectomy, while the incidence of permanent hypocalcemia was a secondary outcome in this analysis. Random-effects models were used for all comparisons in this meta-analysis. In total, 8 RCTs enrolling 1666 patients were incorporated when conducting this meta-analysis. Relative to placebo control treatment, dexamethasone administration was associated with significant reductions in the rates of postoperative symptomatic hypocalcemia (OR = 0.40; 95%CI 0.16-1.00; = 0.050) and biochemical hypocalcemia (OR = 0.34;95%CI 0.14-0.83; = 0.020 ( < 0.05). No differences were detected between these groups with respect to the incidence of permanent hypocalcemia, and no trials revealed any evidence of glucocorticoid-associated complications. Significant heterogeneity was detected among studies, but the exclusion of any single study did not significantly alter study outcomes. The present pooled analyses suggested that one preoperative dexamethasone dose was sufficient to reduce the odds of thyroidectomy patients developing biochemical or symptomatic hypocalcemia within 24 h after the procedure. The prophylactic administration of steroids was both safe and effective, suggesting that it warrants consideration as a component of routine clinical care. However, additional prospective work will be vital to validate the efficacy of dexamethasone as a means of preventing objective hypocalcemia in this patient population.

Diabetes mellitus is a multifactorial metabolic disease, of which type 2 diabetes (T2D) is one of the most common. The complications of diabetes are far more harmful than diabetes itself. Type 2 diabetes complications include diabetic nephropathy (DN), diabetic heart disease, diabetic foot ulcers (DFU), diabetic peripheral neuropathy (DPN), and diabetic retinopathy (DR) . Many animal models have been developed to study the pathogenesis of T2D and discover an effective strategy to treat its consequences. In this sense, it is crucial to choose the right animal model for the corresponding diabetic complication. This paper summarizes and classifies the animal modeling approaches to T2D complications and provides a comprehensive review of their advantages and disadvantages. It is hopeful that this paper will provide theoretical support for animal trials of diabetic complications.

BACKGROUND: Type 2 diabetes (T2D) is one of the most prevalent diseases that also show sexual dimorphism in many different aspects. OBJECTIVES: This study aimed to distinguish the mRNA expression of genes in peripheral blood mononuclear cells (PBMCs) in men or women with T2D using a multistep analysis. METHODS: A total of 95 patients with T2D were compared based on their sex in terms of clinical variables and mRNA expression in their PBMCs. RESULTS: Men with T2D had lower LDLC, HDLC, and HbA1c values in their blood, but greater creatinine levels. In men with T2D, , and mRNA expression was greater, but and mRNA expression was lesser in PBMCs. There was a link between fasting plasma glucose (FPG), triglycerides, and hs-CRP, as well as mRNA in men with T2D. In women with T2D, FPG was associated with the mRNA expression of and , as well as triglycerides and HDLC levels. We found the exclusive effect of FPG on HDLC, HbA1c, as well as mRNA in PBMCs of women with T2D. Analysis revealed the exclusive effect of FPG on hs-CRP and mRNA in PBMCs of men with T2D. FPG was shown to be associated with body mass index, hs-CRP, triglycerides, and mRNA in men with T2D, and with serum triglycerides, , and mRNA in women with T2D, according to network analysis. HbA1c was linked with mRNA in women with T2D. CONCLUSIONS: Using a multistep analysis, it was shown that network analysis outperformed traditional analytic techniques in identifying sex-specific alterations in mRNA gene expression in PBMCs of T2D patients. The development of sex-specific therapeutic approaches may result from an understanding of these disparities.

BACKGROUND: Polycystic ovarian syndrome (PCOS) is a commonly occurring reproductive disorder among the reproductive-aged women. Its global occurrence varies based on diagnostic guidelines, ethnicities, and locations of concern. Insulin resistance (IR) is commonly observed around 65-70% of women diagnosed with PCOS, representing a prevalent association. Consequently, the study was designed with an objective of illustrating the effect of insulin on mural and cumulus granulosa cells (GCs) of PCOS patients in comparison to normal ovulating women. METHODOLOGY: This study is a case-control design, wherein a total of 80 participants were recruited meeting criterion of inclusion and exclusion, divided into 8 groups with each group consisting of 10 samples. The process involves the isolation and culturing of mural granulosa cells (MGC) and cumulus granulosa cells (CGC) with and without exposure to insulin. The proteins released by untreated GCs and insulin-treated GCs were extracted, and complex protein mixtures were digested with trypsin, followed by tandem mass spectrometry analysis and data processing using bioinformatics. RESULTS: We found 595 proteins in both control and PCOS samples, of which 310 were contributed by MGCs and 285 by CGCs. The PCOS MGCs expressed 20%, both the normal MGCs and CGCs have equal representation of 16% by each, whereas the PCOS CGCs proteins contributed 15% of the total of the proteomic expression. However, the poor expression observed with the Insulin exposure, the Insulin treated PCOS CGCs contributes 13%, PCOS MGCs contributes 8%. The normal MGCs upon the Insulin treatment give 8% then and there only 4% of proteins expressed by normal CGCs after Insulin treatment. The Venn analysis widened on their precise expression topographies. The examination of strings exhibited important protein-protein interaction pathways. CONCLUSION: This is a pioneering investigation aimed to establish the link between hyperinsulinemia in localized follicular GCs and PCOS mechanisms by comparing them to control group. The examination of various attributes, mechanisms, and traits shown by genes and proteins in individuals with PCOS compared to control populations, alongside the investigation of the dynamics of these genes and proteins following exposure to insulin, holds promise for the formulation of novel hypotheses and strategies in the identification of new biomarkers.

BACKGROUND AND AIMS: Patients with obesity and type 2 diabetes (T2D) have shown alterations in the affinity of IgG anti-leptin antibodies which are possibly related to metabolic alterations. In the present exploratory study, we analyzed serum samples from adults with T2D classified by body mass index (BMI) and evaluated the relationship of IgG anti-leptin antibodies with body composition, metabolic and cardiovascular risk parameters. METHODS: Serum IgG anti-leptin antibodies (total, free and immune complexes fractions) were measured by in-house ELISA. Body composition, metabolic biomarkers (glucose, glycated hemoglobin, lipid profile, insulin, leptin) and cardiometabolic risk indexes (AIP, HOMA-IR, HOMA-ß) were evaluated in one hundred T2D patients. RESULTS: Patients with T2D and obesity presented a decrease in the percentage of IgG anti-leptin immune complexes compared to patients with T2D and overweight ( < 0.0053). Negative correlations of IgG anti-leptin immune complexes with triglycerides (TG) (=-0.412, = 0.023) and VLDL-C (=-0.611, = 0.017) were found in normal weight T2D patients. Free IgG anti-leptin antibodies correlated positively with TC ( = 0.390, = 0.032) and LDL-C ( = 0.458, = 0.011) in overweight individuals with T2D. Finally, total IgG anti-leptin antibodies correlated positively with leptin hormone levels ( = 0.409, = 0.024) and negatively with HOMA-IR ( =-0.459, = 0.012) in T2D patients with obesity. CONCLUSIONS: The decrease of IgG anti-leptin immune complexes observed in patients with T2D and obesity suggests a reduction in antibody affinity to the hormone that may impact its transport and signaling, lipid, lipoprotein and insulin metabolism.

OBJECTIVES/INTRODUCTION: The purpose of the current study was to investigate the association between Aspartate Transaminase (AST)/Alanine transaminase(ALT) and type 2 diabetes (T2DM) in nonalcoholic fatty liver disease (NAFLD) patients and to determine whether there were sex differences. METHODS: In the retrospective study, we collected data on NAFLD patients (1, 896 men and 465 women) at Murakami Memorial Hospital from 2004 to 2015. Data were stratified by sex to investigate the association between AST/ALT and T2DM incidence by sex. Multiple regression analysis, smooth curve fitting model and subgroup analysis were used to determine the correlation, non-linear relationship and threshold effect between AST/ALT and T2DM. RESULTS: In our study, 157 men and 40 women developed T2DM at follow-up. After adjusting for risk factors, AST/ALT was significantly associated with T2DM in men with NAFLD but not in women with NAFLD. The risk of T2DM increased as the AST/ALT ratio decreased. Besides, in male NAFLD patients, AST/ALT showed a non-linear relationship with T2DM, with an inflection point value of 0.964. When the AST to ALT ratio was below the threshold (AST/ALT <0.964), AST/ALT was significantly negatively associated with T2DM (HR = 0.177, 95% CI 0.055-0.568; = 0.0036). In contrast, when AST/ALT >0.964, no significant association was found (HR = 3.174, 95% CI 0.345-29.167; = 0.3074). Moreover, subgroup analysis showed that GGT could alter the relationship between AST/ALT and T2DM. In the group with GGT ≤ 40, AST/ALT was strongly associated with T2DM (HR = 0.24, 95% CI 0.09-0.66; = 0.0059). CONCLUSIONS: These results suggested that there were sex differences in the association between AST/ALT and T2DM in NAFLD participants. A non-linear association between AST/ALT and T2DM was observed in males. AST/ALT in the normal GGT group (GGT ≤40) might better facilitate the early screening of T2DM.

OBJECTIVE: Follistatin (FST)/myostatin (MST) myokine-signaling axis is important for muscle metabolism and pathogenesis of obesity. FST, mainly secreted by skeletal muscle and liver, inhibits MST and affects skeletal muscle synthesis. This study aimed to identify the characteristics of myokines and independent predictors of serum FST levels in patients with obesity. METHODS: In this retrospective cross-sectional study, 226 patients (mean age, 46.6 years; men, 35.4%) with obesity who initially visited an outpatient clinic between June 2014 and September 2020, were included and classified into obesity (25.0 ≤ body mass index (BMI) < 35.0 kg/m) and severe obesity (BMI ≥35 kg/m) groups based on the guidelines of the Japan Society for the Study of Obesity. Body composition was measured using bioelectrical impedance analysis and computed tomography. Muscle strength, exercise tolerance, metabolic parameters, and myokines were measured, including serum levels of FST, MST, irisin, and brain-derived neurotrophic factor. RESULTS: Serum FST levels were significantly higher in the severe obesity group than in the obesity group (median: 768.4 vs. 895.1 pg/mL, = 0.020). However, the levels of other myokines showed no significant differences between the groups. In Model 1, which included factors that significantly correlated with FST levels, stepwise multivariate regression analysis revealed peak oxygen uptake (VO) as an independent predictor of FST levels based on the significance of the univariate analysis. Additionally, Model 2 was analyzed by adding myokine level to Model 1, revealing that peak VO MST, and irisin levels were independent predictors of FST levels. CONCLUSION: Serum FST levels were higher in patients in the severe obesity group compared to those in the obesity group. There was an independent association between low exercise tolerance and elevated serum FST levels.

BACKGROUND: The purpose of this study was to investigate the preoperative prediction of large-number central lymph node metastasis (CLNM) in single thyroid papillary carcinoma (PTC) with negative clinical lymph nodes. METHODS: A total of 634 patients with clinically lymph node-negative single PTC who underwent thyroidectomy and central lymph node dissection at the First Affiliated Hospital of Anhui Medical University and the Nanchong Central Hospital between September 2018 and September 2021 were analyzed retrospectively. According to the CLNM status, the patients were divided into two groups: small-number (≤5 metastatic lymph nodes) and large-number (>5 metastatic lymph nodes). Univariate and multivariate analyses were used to determine the independent predictors of large-number CLNM. Simultaneously, a nomogram based on risk factors was established to predict large-number CLNM. RESULTS: The incidence of large-number CLNM was 7.7%. Univariate and multivariate analyses showed that age, tumor size, and calcification were independent risk factors for predicting large-number CLNM. The combination of the three independent predictors achieved an AUC of 0.806. Based on the identified risk factors that can predict large-number CLNM, a nomogram was developed. The analysis of the calibration map showed that the nomogram had good performance and clinical application. CONCLUSION: In patients with single PTC with negative clinical lymph nodes large-number CLNM is related to age, size, and calcification in patients with a single PTC with negative clinical lymph nodes. Surgeons and radiologists should pay more attention to patients with these risk factors. A nomogram can help guide the surgical decision for PTC.

BACKGROUND: Androgens induce vasorelaxation and reduce blood pressure in different mammals, including humans. Most women with polycystic ovary syndrome (PCOS), with hyperandrogenism, are obese and exhibit hypertension; thus, the fact that androgens increase blood pressure (BP) is controversial. Our aim was to determine whether hypertension is produced by androgen excess and/or obesity. METHODS: Experiments were performed in dehydroepiandrosterone; (DHEA, s.c)-induced PCOS model. BP from nonobese and obese rats with PCOS (fed a normal or high-fat diet, respectively) was evaluated weekly for 10 weeks by plethysmography and compared between them. We determined whether androgen receptors are responsible for androgen action on BP in rats with PCOS; a group of DHEA-treated rats was implanted with pellets of an antiandrogen and was compared with nonobese rats with PCOS. Isometric tension from aortas of nonobese and obese rats was recorded and compared to explore the integrity of the vascular endothelium when acetylcholine-induced endothelium-dependent vascular relaxation on phenylephrine contraction. Additionally, BP was obtained from 30 women diagnosed with PCOS: nonobese (BMI ≤25) and obese women (BMI ≥35) and compared with healthy counterparts; 15 obese and 15 nonobese women. RESULTS: Nonobese rats and women with PCOS showed hypotension, while obese rats and women with PCOS displayed hypertension. Healthy obese women were hypertensive and nonobese women remained normotensive. Antiandrogen did not modify the BP values in nonobese rats with PCOS, and obese rats with PCOS revealed marked endothelial dysfunction. CONCLUSIONS: Our findings show that obesity is responsible for hypertension in PCOS and partial endothelial damage was observed, which may contribute to elevated BP. Remarkably, hyperandrogenism is capable of regulating BP to low values that are androgen receptor-independent.

OBJECTIVE: Triglyceride-based indices have gained much attention over the past few years. Relation of triglyceride - glucose (TyG) index with insulin resistance and diabetic macrovascular complications was thoroughly studied; nevertheless its relation to microvascular complications is still unclear. This provoked us to carry out the present study. METHODS: This cross-sectional study included 500 patients with type 2 diabetes (T2DM), who were enrolled from the outpatient clinic of the Diabetes and Metabolism Unit at Alexandria Main University Hospital. The equations utilized to calculate triglycerides-related indices were: TyG ratio = fasting triglycerides (mg/dL)/fasting glucose (mg/dL), and TyG index = logarithm of [fasting triglyceride (mg/dl) x fasting glucose (mg/dl)/2]. The diagnostic criteria set by the American Diabetes Association were followed to diagnose diabetic microvascular complications. RESULTS: In patients with T2DM, TyG index was significantly higher in patients with diabetic retinopathy, diabetic kidney disease, and diabetic peripheral neuropathy compared to those without complications ( < 0.001). TyG index was significantly positively correlated to diabetes duration, as well as triglyceride/high density lipoprotein ratio in the total sample ( < 0.001). CONCLUSION: TyG index is an easy, cheap, and available marker for detection of microvascular complications in patients with T2DM.

CONTEXT: Coronavirus disease 2019 (COVID-19) predominantly involves the lungs, albeit many other organ systems, including the hypothalamic-pituitary-adrenal (HPA) axis, can be affected due to the expression of the angiotensin-converting enzyme 2 (ACE2) binding receptor. Few studies have reported the involvement of adrenal gland and the HPA axis during the acute phase of COVID-19; however, the data on the long-term effect of COVID-19 on the HPA axis after acute infection is scarce. OBJECTIVE: To assess and compare the changes in HPA axis in mild, moderate and severe COVID-19 categories at ≥ 3 months after acute infection. METHODS: A prospective, observational study was conducted to assess the HPA axis status among COVID-19 subjects at least 3 months after recovery from acute infection. The study was conducted from June 2021 to May 2022. Subjects visited the hospital in the fasting state (8.00-9.00am), serum cortisol levels were measured at baseline, 30 and 60 minutes after a 1-μg short Synacthen test (SST). RESULTS: A total of 66 subjects ≥ 18 years of age were included in the study. The mean age (SD) was 49.13 ± 11.9 years, 45(68.18%) were male and 21 (31.81%) were female subjects. The mean BMI in the study was 25.91 ± 4.26 kg/m. Seventeen (25.8%) subjects had mild, twelve (18.2%) had moderate and thirty-seven (56.1%) subjects had severe COVID-19 infection. Out of the sixty-six subjects with COVID-19, nine subjects (9/66, 13.63%) had peak serum cortisol < 496.62 nmol/L suggestive of adrenal insufficiency (AI). SST peak serum cortisol levels did not differ significantly across the disease severity [Mild, (628.50 ± 214.65 nmol/L) vs moderate, [603.39 ± 161.95 nmol/L) vs severe, (597.59 ± 163.05 nmol/L), = 0.617]. Six subjects with AI came for follow-up at 12 months, and all had normal HPA axis. CONCLUSION: HPA axis is affected in 13.63% (9/66) of subjects at least 3 months after recovery from COVID-19 infection. AI in COVID-19 might be transient and would recover spontaneously. These findings have important implications for the clinical care and long-term follow-up of subjects after COVID-19 infection.

This study aimed to examine the impact of hyperuricemia on various thyroid disorders with emphasized focus on differences resulting from different genders. 16094 adults aged ≥18 years were enrolled in this cross-sectional study using a randomized stratified sampling strategy. Clinical data including thyroid function and antibodies, uric acid, and anthropometric measurements were measured. Multivariable logistic regression was used to determine the association between hyperuricemia and thyroid disorders. Women who have hyperuricemia are at a significantly increased risk of developing hyperthyroidism. Women's risk of overt hyperthyroidism and Graves' disease may be markedly increased by hyperuricemia. Men with hyperuricemia did not differ significantly in their chance of acquiring any thyroid disorders.

BACKGROUND: Intravenous glucocorticoid (IVGC) remains the main treatment for moderate-to-severe and active thyroid-associated ophthalmopathy (TAO). However, a substantial number (20-30%) of active moderate-to-severe TAO patients may not respond to IVGC. Some patients may have disease progression despite IVGC treatment or relapse after steroid withdrawal. OBJECTIVES: To analyze risk factors for clinical activity and predictive factors for clinical outcomes of 4.5 g IVGC therapy in patients with moderate-to-severe TAO. DESIGN AND METHODS: Our study was performed in two steps: step 1 involved 110 moderate-to-severe TAO patients and analyzed risk factors for TAO activity; step 2 involved 53 active moderate-to-severe TAO patients from step 1 who were treated with 4.5 g IVGC therapy and analyzed predictive factors for clinical outcomes of IVGC therapy. Multivariate logistic regression analysis was used to identify the independent predictors and establish the predictive model. RESULTS: Abnormal TRAb (OR = 4.717; = 0.019) and the percentage of CD3+CD4+ T cell (OR = 1.092; = 0.028) were independently associated with the activity of moderate-to-severe TAO patients. The pretreatment CAS-max in both eyes (OR = 7.221; = 0.013) and the percentage of pretreatment CD3+T cell (OR = 0.718; = 0.037) were independently associated with therapeutic efficacy. The pretreatment CAS-max in both eyes (OR = 156.53; = 0.028) and the percentage of post-treatment CD3+T cell (OR = 0.554; = 0.043) were independently associated with therapeutic efficacy. Besides, multivariable prediction models were established, which were better in the forecasting aspect than single-variable prediction models. CONCLUSIONS: Based on the findings of this study, we should monitor the peripheral blood T cell subsets for TAO, which could be helpful to timely judge the condition of clinical manifestation and effect of treatment for TAO patients. Multivariable prediction models have been established, which have great significance for clinical work.

Limited data are available regarding the association between pre-admission thyroid-stimulating hormone (TSH) levels and prognosis in hospitalized surgical patients treated for hypothyroidism. We retrospectively evaluated a cohort of 1,451 levothyroxine-treated patients, hospitalized to general surgery wards. The 30-day mortality risk was 2-fold higher for patients with TSH of 5.0-10.0 mIU/L (adjusted OR, 2.3; 95% CI 1.1-5.1), and 3-fold higher for those with TSH > 10.0 mIU/L (3.4; 95% CI 1.3-8.7). Long-term mortality risk was higher in patients with TSH of 5.0-10.0 and above 10.0 mIU/L (adjusted HR, 1.2; 95% CI, 1.0-1.6, and 1.7; 95% CI 1.2-2.4, respectively). We found that in levothyroxine-treated adults hospitalized to surgical wards, increased pre-admission TSH levels are associated with increased short- and long-term mortality.
