Impact of COVID-19 on the mental health of primary schoolchildren during the later phase of the pandemic: A case report of an 18-month longitudinal survey in a Japanese primary school. PUBLIC HEALTH IN PRACTICE 2024; 7:100471. [PMID: 38328526 PMCID: PMC10847696 DOI: 10.1016/j.puhip.2024.100471] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Revised: 01/17/2024] [Accepted: 01/19/2024] [Indexed: 02/09/2024] Open
Abstract
Background Drastic changes such as school closures and stay-at-home measures due to the global COVID-19 pandemic, may have long-term negative effects on children's mental health; however, longitudinal studies after 2021 are limited. This study aimed to observe the long-term effects of the COVID-19 pandemic on children's mental health by exploring changes in their mental health over a period of 18 months. Study design We conducted a longitudinal study at Chiba Prefecture in Japan, focusing on schoolchildren's mental health changes. Methods Data were obtained from the Strengths and Difficulties Questionnaire (SDQ) questionnaire conducted at single primary school three times from October 2021 to March 2023 which and included 183 participants. This study adopted a linear-mixed model to evaluate changes in children's SDQ scores, with sex and grade as the independent variables, and participants as a random effect. Results Regarding changes in SDQ scores, there were no significant changes in the total difficulty scores or in each subscale; Emotional Symptoms, Conduct Problems, Hyperactivity/Inattention, Peer Problems, and Prosocial Behavior. There was no statistically significant interaction between changes in SDQ scores and sex. Conclusions This report indicates that the impact of the COVID-19 pandemic on the mental health of Japanese primary schoolchildren was negligible in the later phase of the pandemic. However, the impact may differ from country to country owing to factors such as social restrictions during the COVID-19 pandemic.

Abstract
Agranulocytosis is a serious adverse effect of methimazole (MMI) and propylthiouracil (PTU), and although there have been reports suggesting a dose-dependent incidence in relation to both drugs, the evidence has not been conclusive. The objective of our study was to determine whether the incidences of agranulocytosis induced by MMI and PTU exhibit dose-dependency. The subjects were 27,784 patients with untreated Graves' disease, 22,993 of whom were on an antithyroid drug treatment regimen for more than 90 days. Within this subset, 18,259 patients had been treated with MMI, and 4,734 had been treated with PTU. The incidence of agranulocytosis according to dose in the MMI group was 0.13% at 10 mg/day, 0.20% at 15 mg/day, 0.32% at 20 mg/day, and 0.47% at 30 mg/day, revealing a significant dose-dependent increase. In the PTU group, there were 0 cases of agranulocytosis at doses of 125 mg/day and below, 0.33% at 150 mg/day, 0.31% at 200 mg/day, and 0.81% at 300 mg/day, also revealing a significant dose-dependent increase. The incidence of agranulocytosis at MMI 15 mg and PTU 300 mg, i.e., at the same potency in terms of hormone synthesis inhibition, was 0.20% and 0.81%, respectively, and significantly higher in the PTU group. Our findings confirm a dose-dependent increase in the incidence of agranulocytosis with both drugs, but that at comparable thyroid hormone synthesis inhibitory doses PTU has a considerably higher propensity to induce agranulocytosis than MMI does.

Abstract
Proper regulation of N-methyl-D-aspartate-type glutamate receptor (NMDA receptor) expression is responsible for excitatory synaptic functions in the mammalian brain. NMDA receptor dysfunction can cause various neuropsychiatric disorders and neurodegenerative diseases. Posttranslational protein S-palmitoylation, the covalent attachment of palmitic acid to intracellular cysteine residues via thioester bonds, occurs in the carboxyl terminus of GluN2B, which is the major regulatory NMDA receptor subunit. Mutations of three palmitoylatable cysteine residues in the membrane-proximal cluster of GluN2B to non-palmitoylatable serine (3CS) lead to the dephosphorylation of GluN2B Tyr1472 in the hippocampus and cerebral cortex, inducing a reduction in the surface expression of GluN2B-containig NMDA receptors. Furthermore, adult GluN2B 3CS homozygous mice demonstrated a definite clasping response without abnormalities in the gross brain structure, other neurological reflexes, or expression levels of synaptic proteins in the cerebrum. This behavioral disorder, observed in the GluN2B 3CS knock-in mice, indicated that complex higher brain functions are coordinated through the palmitoylation-dependent regulation of NMDA receptors in excitatory synapses.

Abstract
Background The remote performance of thyroid function blood tests is complicated because it requires blood collection. Objective To compare TSH and free thyroxine (FT4) levels between capillary and venous blood and assess the adequacy of measuring each value in capillary blood. Methods This prospective intervention study was conducted at Ito Hospital and was based on the clinical research method. The participants were 5 healthy female volunteers and 50 patients (41 females and 9 males) between the ages of 23 and 81 years. To measure TSH and FT4 levels in capillary and venous blood, a digital immunoassay (d-IA) method capable of measuring trace samples was used. Chemiluminescence measurements were used as controls. Values obtained for each assay system were compared using Spearman's correlation analysis. Capillary blood was collected using an autologous device (TAP II; not approved in Japan). Results Capillary plasma volume obtained using TAP II was 125 µL or more in 26 cases, 25 µL to 124 µL in 24 cases, and less than 25 µL in 5 cases. Strong correlations were noted in the TSH and FT4 levels between capillary and venous blood, with correlation coefficients of rs = 0.99 and rs = 0.97, respectively. Conclusion Capillary TSH and FT4 levels strongly correlate with venous blood values. Trace samples can be used in high-precision d-IA methods. These results may promote telemedicine in assessing thyroid function.

Abstract
Objective This study assessed the efficacy of machine learning in predicting thyrotoxicosis and hypothyroidism [thyroid-stimulating hormone (TSH) >10.0 mIU/L] by leveraging age and sex as variables and integrating biochemical test parameters used by the Japan Society of Health Evaluation and Promotion (JHEP) and the Japan Society of Ningen Dock (JND). Subjects and Methods Our study included 20,653 untreated patients with Graves' disease, 3,435 untreated patients with painless thyroiditis, 4,266 healthy individuals, and 18,937 untreated patients with Hashimoto's thyroiditis. Machine learning was conducted using Prediction One on three distinct datasets: the Ito dataset (age, sex, and 30 blood tests and biochemical test data), the JHEP dataset (age, sex, and TP, T-Bil, AST, ALT, γGTP, ALP, CRE, UA, and T-Cho test data), and the JND dataset (age, sex, and AST, ALT, γGTP, CRE, and UA test data). Results The results for distinguishing thyrotoxicosis patients from the healthy control group showed that the JHEP dataset yielded substantial discriminative capacity with an area under the curve (AUC) of 0.966, sensitivity of 92.2%, specificity of 89.1%, and accuracy of 91.7%. The JND dataset displayed similar robustness, with an AUC of 0.948, sensitivity of 92.0%, specificity of 81.3%, and accuracy of 90.4%. Differentiating hypothyroid patients from the healthy control group yielded similarly robust performances, with the JHEP dataset yielding AUC, sensitivity, specificity, and accuracy values of 0.864, 84.2%, 72.1%, and 77.4%, respectively, and the JND dataset yielding values of 0.840, 83.2%, 67.2%, and 74.3%, respectively. Conclusions Machine learning is a potent screening tool for thyrotoxicosis and hypothyroidism.

Abstract
Appropriate administration of anti-inflammatory and immunosuppressive treatment (AIIST) is important for patients with Graves' orbitopathy (GO). This study aimed to clarify the incidence and risk factors for GO treated with AIIST and propose a predictive score, among newly diagnosed Graves' disease (GD) patients in Japan. A total of 1,553 GD patients who were newly diagnosed during the year 2011 were investigated. AIIST included local and/or systemic glucocorticoid administration and retrobulbar irradiation. A multivariable Cox proportional hazards model was used to investigate the risk factors for GO underwent AIIST during medical treatment, including at diagnosis, of GD. Then, a GO score was created by summing each point assigned to risk factors based on their coefficient obtained in the Cox model. AIIST was administered to 107 patients (6.9%). The risk factors and hazard ratios for GO underwent AIIST were: age (per 10 years), 1.32 (95% confidence interval: 1.16-1.50), p < 0.0001; TSH binding inhibitory immunoglobulin (TBII) (per 10 IU/L), 1.33 (1.15-1.54), p = 0.0001; and thyroglobulin antibody (TgAb) negativity, 2.98 (1.96-4.59), p < 0.0001. The GO score, ranging from 0 to 8 points, showed moderate performance (area under the curve: 0.71, cut-off value: 5 points, sensitivity: 0.76, specificity: 0.59, positive predictive value: 0.12, negative predictive value: 0.97). AIIST was performed for patients with active manifestations of GO in 6.9% of newly diagnosed GD patients. The risk factors for GO underwent AIIST were higher age, higher TBII, and TgAb negativity. The GO score based on these factors may be useful in managing GO.

Abstract
BACKGROUND AND AIM Apolipoprotein A2 (apoA2) isoforms have been reported to undergo the aberrant processing in pancreatic cancer and pancreatic risk populations compared with that in healthy subjects. This study aimed to clarify whether apoA2 isoforms were as useful as N-benzoyl-p-aminobenzoic acid (BT-PABA) test for exocrine pancreatic dysfunction markers in patients with early chronic pancreatitis (ECP). METHODS Fifty consecutive patients with functional dyspepsia with pancreatic enzyme abnormalities (FD-P) (n = 18), with ECP (n = 20), and asymptomatic patients with pancreatic enzyme abnormalities (AP-P) (n = 12) based on the Rome IV classification and the Japan Pancreatic Association were enrolled in this study. The enrolled patients were evaluated using endoscopic ultrasonography and endoscopic ultrasonography elastography. Five pancreatic enzymes were estimated. Pancreatic exocrine function was analyzed using the BT-PABA test. Lighter and heavier apoA2 isoforms, AT and ATQ levels were measured by enzyme-linked immunosorbent assay methods. RESULTS There were no significant differences in clinical characteristics such as age, gender, body mass index, alcohol consumption and smoking among patients with AP-P, FD-P, and ECP. The BT-PABA test and lighter apoA2 isoform, AT level in the enrolled patients had a significant correlation (P < 0.01). The BT-PABA test in patients with ECP was significantly lower (P = 0.04) than that in AP-P. ApoA2-AT level in patients with ECP was lower than that in AP-P, albeit, insignificantly. Interestingly, apo A2-AT level was significantly (P = 0.041) associated with exocrine pancreatic insufficiency by multiple logistic regression analysis. CONCLUSIONS ApoA2-AT level is a useful tool to evaluate exocrine pancreatic insufficiency in the early stage of chronic pancreatitis.

Abstract
The present study aimed to establish new reference intervals (RIs) for serum free triiodothyronine (fT3), free thyroxine (fT4), and thyroid stimulating hormone (TSH) levels in Japanese children and adolescents aged 4 to 19 years. A total of 2,036 (1,611 girls, 425 boys) participants were included over a 17-year period; they all tested negative for antithyroid antibodies (TgAb, TPOAb) and were found to have no abnormalities on ultrasonography. RIs were determined by nonparametric methods. The results showed that serum fT3 was significantly higher in the 4-15-year-olds than in the 19-year-olds. The serum fT4 was significantly higher in the 4-10-year-olds than in the 19-year-olds. The serum TSH was significantly higher in the 4-12-year-olds than in the 19-year-olds. All of them gradually decreased with age to approximate the adult levels. The upper limit of TSH was lower in those aged 13 to 19 years than in adults. The differences were examined by sex. The serum fT3 was significantly higher in boys than in girls between the ages of 11 and 19 years. The serum fT4 was significantly higher in boys than in girls between the ages of 16 and 19 years. There did not seem to be any sex difference in those under 10 years of age. In conclusion, serum fT3, fT4, and TSH levels in children and adolescents differ from those in adults. It is important to evaluate thyroid function using the new RIs that are appropriate for chronological age.

Abstract
This study aimed to investigate adverse reactions to medications administered during palliative care and compare the responses of Board-Certified Pharmacists in Palliative Pharmacy (BCPPP) and non-BCPPP professionals. Methods: This multicentre prospective survey included hospital and community pharmacists who are members of the Japanese Society for Pharmaceutical Palliative Care and Sciences. Study participants included patients who experienced new drug reactions during the study period and responded to the requested survey items. The follow-up period for each eligible patient began on the day the pharmacists initiated the intervention and ended at discharge, death, or after one month of intervention. The primary endpoint was the impact of pharmacist intervention on adverse drug reactions. The pharmacists included in the study evaluated the severity of adverse drug reactions to assess the effect of their intervention using an integrated palliative care outcome scale before and after the intervention. Key findings: During the survey period, 79 adverse drug reaction intervention reports from 69 patients were obtained from 54 pharmacists (28 certified and 26 non-certified). The response rate was 1.62% (54/3,343). The management of palliative pharmacotherapy side effects by BCPPP and non-BCPPP significantly improved the patients' activities of daily living (P < 0.001). The BCPPP group intervened for significantly more patients with adverse drug reactions and overall adverse drug reactions than the non-BCPPP group (P < 0.023 and P < 0.013, respectively). Conclusion: BCPPP interventions can improve symptom management.

Abstract
Background: The incidence of neonatal hypothyroidism among newborns born to mothers with Graves' disease (GD) who continued antithyroid drug (ATD) treatment until delivery has never been reported. Objective: Our primary objective was to investigate the incidence of neonatal hypothyroidism among newborns born to mothers with GD who were treated with ATD until delivery. Our secondary objective was to identify the cutoff ATD daily doses for neonatal hypothyroidism risk, based on maternal thyrotropin (TSH) receptor antibody (TRAb) levels. Methods: We conducted a retrospective cohort study. We included 305 pregnant women with GD who were treated with an ATD until delivery (63 treated with methimazole [MMI] and 242 treated with propylthiouracil [PTU]). Umbilical cord TSH, free thyroxine (fT4), and TRAb levels were measured at delivery, and we investigated the respective relationships between neonatal hypothyroidism at delivery and maternal fT4 levels, TRAb levels, and daily ATD doses during pregnancy. Neonatal hypothyroidism was diagnosed when the umbilical cord fT4 level was below the lower limit of the reference range. Results: The incidence of neonatal hypothyroidism at delivery was 19.0% ([confidence interval, CI, 11.2-30.4]; 12/63) in the MMI group and 12.8% ([CI, 9.2-17.6]; 31/242) in the PTU group. Neonatal goiter was observed in one neonate in the PTU group, and two infants in the PTU group required levothyroxine treatment. The daily ATD dose in the third trimester was the strongest predictor of neonatal hypothyroidism at delivery; the cutoff MMI dose was 10 mg/day, and the cutoff PTU dose was 150 mg/day. When the maternal TRAb level in the third trimester was above three times the upper limit of the normal range, the cutoff MMI dose was 20 mg/day, and the cutoff PTU dose was 150 mg/day. Conclusions: Maternal fT4 and TRAb levels were higher in the neonatal hypothyroid group, which suggested prolonged GD activity. Careful follow-up is necessary when maternal GD remains active and the ATD dose to control maternal thyrotoxicosis cannot be reduced.

Abstract
Graves' disease has been reported to affect the clinical features of moyamoya disease (MMD), an occlusion of the circle of Willis. This study aimed to clarify the characteristics of MMD in patients with Graves' disease. This was a single-center, retrospective study. The prevalence and clinical features of MMD patients among all patients with thyroid disease who visited Ito Hospital from January 2005 to December 2019 were evaluated. The relationship between MMD and hyperthyroidism was analyzed in new-onset Graves' disease patients during the same period. Of all 394,422 patients with thyroid disease, 88,180 had Graves' disease, and 40 had MMD with Graves' disease, i.e., the prevalence was 45.36 per 100,000 patients with Graves' disease (0.0454%). The median age at onset of MMD was 39 years (interquartile range, 31-54 years), with a male to female ratio of 1:12. The most common time that MMD was diagnosed was within 1 year after the onset of Graves' disease, in 9 of 40 patients (22.5%), and 19 of 40 patients (47.5%) underwent bypass surgery for MMD. In MMD with Graves' disease, headache was the most frequent symptom, and ischemic types of stroke and bilateral lesions were common. Of 23,347 patients with new-onset Graves' disease, 7 were diagnosed with MMD and the incidence of MMD was 5.94 patients per 100,000 person-years. Most patients developed MMD symptoms during hyperthyroidism. Although MMD is a rare condition, it should be noted that it can occur with Graves' disease.

Abstract
The effect of potassium iodide (KI) on radioiodine uptake (RAIU) before radioisotope therapy in Graves' disease (GD) patients was investigated. A total of 82 patients who had been treated with KI monotherapy before 24-hour RAIU (24 h RAIU) were evaluated and 354 of those who had been treated with thiamazole (MMI) monotherapy were extracted from the 1,130 GD patients who were identified as having had appropriate iodine restriction based on urinary iodine excretion. Urinary iodine excretion (UIE) <200 μg/day was confirmed in all subjects. Propensity score-matching was performed to identify the difference in 24 h RAIU between the KI group and the MMI group. In addition, multiple regression analysis was performed to evaluate related to 24 h RAIU. Propensity score-matching resulted in 57 matched patients in each group. After matching, 24 h RAIU was still significantly lower in the KI group than in the MMI group (median 53% (interquartile range 47-61%) vs. 63% (56-66%); p = 0.001). In addition, KI monotherapy was weakly negatively correlated with 24 h RAIU, whereas the female sex and FT3 were very weakly positively correlated on multiple regression analysis. The results suggest that KI monotherapy likely suppressed 24 h RAIU more than MMI monotherapy in GD patients with appropriate iodine restriction, given the difference in the mechanism of hormone suppression.

Abstract
PURPOSES To establish the appropriate staging system and assess the role of curative thyroidectomy alone (Surgery) vs. involved-site radiation therapy after open biopsy (OB-ISRT) in stage IE mucosa-associated lymphoid tissue (MALT) lymphoma. METHODS We examined the Tokyo Classification as a modified classification. This retrospective cohort study included 256 patients with thyroid MALT lymphoma; 137 underwent standard therapy (i.e., OB-ISRT) and were enrolled for the Tokyo classification. Sixty stage IE patients with the same diagnosis were examined to compare Surgery with OB-ISRT. RESULTS Overall survival (p = 0.0092) and relapse-free survival (0.00113) were significantly better in stage IE vs. stage IIE under the Tokyo classification. No OB-ISRT and Surgery patients died, but three OB-ISRT patients relapsed. The incidence of permanent complications was 28% in OB-ISRT (mainly dry mouth) and 0% in Surgery (p = 0.027). The number of painkiller prescription days was significantly greater in OB-ISRT (p < 0.001). During follow-up, the rate of the new appearance/change of the low-density area in the thyroid gland was significantly higher in OB-ISRT (p = 0.031). CONCLUSIONS The Tokyo classification allows an appropriate discrimination between stages IE and IIE MALT lymphoma. Surgery can provide a good prognosis in stage IE cases; it also avoids complications, shortens painful periods during treatment, and simplifies ultrasound follow-up.

Abstract
BACKGROUND More than 40 years have passed since the introduction of newborn screening for congenital hypothyroidism (CH), and many early diagnosed patients have reached adulthood. Their thyroid morphology and function have been little studied. This cross-sectional, observational study was conducted to characterize the thyroid morphology and function of adult CH patients diagnosed in the framework of newborn screening for CH. METHODS A total of 103 adult CH patients born after 1979 were enrolled at Ito Hospital, Tokyo, Japan, and were classified into Goiter, Normal gland, and Dysgenesis groups based on ultrasonographic findings. For 60 patients, genetic analysis was performed. Thyroid function test results and the proportion of patients with thyroid nodules were compared among the three groups and between 56 female CH patients and 168 non-CH women matched for TSH levels. RESULTS A significantly low serum free T3/free T4 ratio (0.22) was observed in the Dysgenesis group. Thyroid nodules were detected in 14.3% (8/56) of female CH patients, more frequently than in non-CH women. Thyroid nodules were detected the most frequently in the Goiter group (71%, 10/14). Genetic defects were identified in 89% (8/9) of patients belonging to the Goiter group, including thyroglobulin defect (33%, 3/9), thyroid peroxidase defect (33%, 3/9), and dual oxidase 2 defect (22%, 2/9). CONCLUSIONS Our results suggest that adults with thyroid dysgenesis on levothyroxine replacement therapy have relative T3 deficiency. Most adults with goitrous CH have genetic dyshormonogenesis. They are at high risk of developing thyroid nodules. Our findings support the current guideline recommendation that CH patients with dyshormonogenesis should undergo periodic thyroid ultrasonography.

Abstract
1. This study assessed 1) the effects of Paracoccus carotinifaciens supplementation containing high astaxanthin levels on egg production performance and quality, 2) dynamics of carotenoids levels in the egg yolk and 3) taste of astaxanthin-rich egg yolk.2. Laying hens were fed diets containing different levels of P. carotinifaciens-derived astaxanthin (ASX; 0, 2, 4, 8, or 16 ppm) for 28 d (experiment 1) or a diet containing 16 ppm astaxanthin for 28 d followed by a 0 ppm astaxanthin diet for 28 days (experiment 2).3. Production performance, egg quality and egg yolk carotenoid levels were examined in experiment 1 (Ex1) and the dynamics of egg yolk carotenoid levels and egg yolk taste in experiment 2 (Ex2).4. ASX supplementation did not affect production performance or egg quality. ASX levels in the egg yolk became saturated after seven days of 16 ppm supplementation and decreased to less than one-tenth of the saturated levels seven days after supplementation cessation. Supplementation with 16 ppm ASX for 28 d did not affect egg yolk taste.5. Supplementation resulted in the production of ASX-rich eggs for a brief period without affecting production performance, egg quality or taste. Understanding the time taken for the incorporation of ASX into egg yolks is beneficial for value-added egg production and may help in minimising supplementation costs.

Abstract
Background: The severity of hyperthyroidism in Graves' disease (GD) has been reported to be worse in younger patients and to gradually improve with advancing age, accompanied by declining thyrotropin (TSH) receptor antibody (TRAb) values. This study was conducted to explore the extent to which the declining TRAb production may contribute to a decrease in severe hyperthyroidism with advancing age in patients with GD. Methods: This study was a cross-sectional analysis of retrospectively reviewed data. The medical records of patients newly diagnosed with GD at Ito Hospital, between January 2005 and June 2019, were examined. Patients were divided into age-stratified groups for evaluation. Multivariable logistic regression was performed to estimate the odds ratio (OR) of severe hyperthyroidism by increasing age. Mediation analyses were also conducted to quantify the association between age and declining severity of hyperthyroidism mediated through decreased TRAb productivity. Results: A total of 21,018 patients with newly diagnosed GD (3848 male and 17,170 female) were included. A correlation was observed between TRAb value and thyroid hormone values in each age-stratified group, which became weaker with an increase in age. Patients aged <40 years had a higher risk of severe hyperthyroidism (free thyroxine [fT4] level >7.0 ng/dL [n = 5616], OR [confidence interval, CI] = 1.80 [1.68-1.92]; free triiodothyronine [fT3] level >25 pg/mL [n = 4501], OR [CI] = 2.06 [1.92-2.23]) than those aged ≧40 years. In examining the relationship between age and severe hyperthyroidism, the proportion mediated through TRAb productivity was 8.5% and 8.4% using fT4 and fT3 as an outcome index, respectively. Conclusions: Declining TRAb value mediated only 8.5% of the negative association between age and severity of hyperthyroidism. The presence of other underlying mechanisms, such as the decline in the reactivity of thyrocytes to TSH stimulation, requires further investigation.

Abstract
Although untreated Graves' disease (GD) is associated with a higher risk of cardiac complications and mortality, there is no well-established way to predict the onset of thyrotoxicosis in clinical practice. The aim of this study was to identify important variables that will make it possible to predict GD and thyrotoxicosis (GD + painless thyroiditis (PT)) by using a machine-learning-based model based on complete blood count and standard biochemistry profile data. We identified 19,335 newly diagnosed GD patients, 3,267 PT patients, and 4,159 subjects without any thyroid disease. We built a GD prediction model based on information obtained from subjects regarding sex, age, a complete blood count, and a standard biochemistry profile. We built the model in the training set and evaluated the performance of the model in the test set by using the artificial intelligence software Prediction One. Our machine learning-based model showed high discriminative ability to predict GD in the test set (area under the curve [AUC] 0.99). The main contributing factors to predict GD included age and serum creatinine, total cholesterol, alkaline phosphatase, and total protein levels. We still found high discriminative ability even when we restricted the variables to these five most contributory factors in our prediction model (AUC 0.97) built by using artificial intelligence software showed high GD prediction ability based on information regarding only five factors.

Abstract
BackgroundElevated serum IgG4 levels are one of the characteristic findings in immunoglobulin G4 (IgG4)-related disease (IgG4-RD). Serum IgG4 levels have an impact to a certain extent on the diagnosis of IgG4-RD although there are some issues in their sensitivity and specificity. In the reports from Japan, China, USA, and Europe, elevated serum IgG4 levels were reported to be observed in 83-97% of patients with IgG4-RD [1-5]. In the past investigations of hospital patients, some studies reported that 10-15% of hospital patients with elevated serum IgG4 levels had IgG4-RD [6,7]. However, in general adults with no symptom, investigations of prevalence of elevated serum IgG4 levels and/or IgG4-RD have rarely been conducted.ObjectivesThis study aimed to investigate the frequency of serum IgG4 elevation in the general Japanese population and its associated factors using data from resident examinations.MethodsWe measured the serum IgG4 levels in 1,204 residents who underwent a general medical examination in Ishikawa prefecture, Japan. Logistic regression analysis was used to search for factors related to elevated serum IgG4 levels. Secondary examinations were conducted for participants in whom elevation was identified.ResultsThe mean serum IgG4 level was 44 mg/dL, and elevated serum IgG4 levels were observed in 42 patients (3.5%). Univariate logistic regression analyses showed that male sex, older age, lower estimated glomerular filtration rates based on cystatin C (eGFR-CysC), serum high-density lipoprotein cholesterol levels, and higher hemoglobin A1c (HbA1c) levels were associated with elevated serum IgG4 levels. Subgroup analyses in men showed that older age, lower eGFR-CysC levels, and higher serum HbA1c levels were associated with elevated serum IgG4 levels. In contrast, the analyses in women found no significant factors. One of the 10 residents who underwent secondary examinations was diagnosed with possible IgG4-related retroperitoneal fibrosis.ConclusionIn the general population, elevated serum IgG4 levels are more common in elderly men, which is similar to the epidemiological features of IgG4-RD.References[1]Inoue D, et al.

Abstract
Background: Primary thyroid lymphoma (PTL) is known to develop mostly in patients with Hashimoto's thyroiditis (HT), and it is rare for it to develop in patients with Graves' disease (GD). The objective of this study was to investigate the clinical features, pathological findings, and long-term outcomes of PTL patients, grouped according to the presence of GD, HT, or no autoimmune thyroid disease (AITDs). The GD group was of major interest due to limited knowledge of the relationship with PTL. Methods: In this single-center retrospective cohort study, we reviewed the medical records of all patients diagnosed with PTL between August 1979 and October 2021, and we characterized the patients according to the presence of HT, GD, or no AITDs. Pathological specimens were classified according to the World Health Organization classification. Staging was performed in accordance with the Ann Arbor classification. Results: During the 42-year period, 498 participants were diagnosed with PTL. The median age was 68 (interquartile range 61-76) years, and 221 patients were stage IE, whereas the remaining 277 patients were stage IIE. Of the PTL patients, 431 (86.6%) were diagnosed with HT, 9 (1.8%) were diagnosed with GD, and 58 (11.6%) did not have AITDs. All nine patients with GD were positive for anti-thyroglobulin antibody and/or anti-thyroid peroxidase antibody. All patients with GD were treated with anti-thyroid medication. There were no significant differences in the proportions of each subtype of PTL between the PTL patients with GD and all subjects with PTL (p = 0.51), PTL patients with HT (p = 0.51), or PTL patients without AITDs (p = 0.48). The median follow-up time was 6.2 (interquartile range 3.0-10.7) years after the diagnosis of PTL. The Kaplan-Meier curve analyses showed no significant differences in overall survival and event-free survival between PTL patients with GD and those with HT (p = 0.37), or between PTL patients with GD and those without AITDs (p = 0.43). Conclusions: The PTL was observed with HT in a majority of cases, and rarely with GD (1.8%). The proportions of each pathological subtype of PTL and the prognosis of PTL were not different between the patients with GD and those with HT or those without AITDs.

Abstract
Context The indirect effects of the COVID-19 pandemic on clinical practice have received great attention, but evidence regarding thyroid disease management is lacking. Objective We aimed to investigate the association between delayed follow-up visits during the pandemic and their serum thyrotropin (TSH) levels among patients being treated with levothyroxine. Methods This study included 25 361 patients who made a follow-up visit as scheduled (n = 9063) or a delayed follow-up visit (< 30 d, n = 10 909; ≥ 30 d, n = 5389) during the pandemic (after April 2020) in Japan. We employed modified Poisson models to estimate the adjusted risk ratio (aRR) of TSH greater than 4.5 mIU/L and greater than 10 mIU/L during the pandemic according to the 3 types of follow-up visit group (ie, as scheduled, delayed < 30 d, and delayed ≥ 30 d). The models included age, sex, city of residence, TSH levels, underlying thyroid disease, dose of levothyroxine, and duration of levothyroxine prescriptions. Results The mean age was 52.8 years and women were 88%. Patients who were older and had a higher dose or longer duration of levothyroxine prescriptions were more likely to make a delayed follow-up visit during the pandemic. Changes in TSH were larger among the delayed-visit groups than the scheduled-visit group. We found increased risks of elevated TSH levels during the pandemic among the delayed visit groups, particularly those with delayed visit of 30 or more days (TSH > 4.5 mIU/L, aRR [95% CI] = 1.72 [1.60-1.85]; and TSH > 10 mIU/L, aRR [95% CI] = 2.38 [2.16-2.62]). Conclusion A delayed follow-up visit during the COVID-19 pandemic was associated with less well-controlled TSH among patients with levothyroxine.

Abstract
INTRODUCTION High-sensitive cardiac troponin reflects micro-myocardial injury in the absence of overt myocardial infarction. OBJECTIVE This study aimed to clarify how thyrotoxicosis affects cardiac troponin. METHODS This was a prospective observational study in Japan. Untreated patients with thyrotoxicosis who visited Ito Hospital were enrolled, and medical treatment was initiated for hyperthyroidism. Thyroid function, high-sensitive troponin I (hsTnI), and brain natriuretic peptide (BNP) were measured at baseline and then every 3 months for 1 year. RESULTS Data from a total of 143 patients (median age, 42 years; 32 men and 111 women) were investigated. At baseline, median hsTnI was 1.9 pg/mL and ranged from 0 to 69.6 pg/mL. Five patients (3.5%) had a high hsTnI value that exceeded 26.2 pg/mL, which is used as the cutoff for diagnosis of myocardial infarction, and 22 patients (15.4%) had an intermediate value between 5.0 and 26.2 pg/mL. Multivariable regression analysis showed that significant predictors of the hsTnI value were age (β = 0.20, p = 0.01) and BNP (β = 0.43, p < 0.0001) (R2 = 0.27, F = 26.0, p < 0.0001), and significant predictors of the BNP value were age (β = 0.23, p = 0.001), hemoglobin (β = -0.43, p < 0.0001), free T4 (FT4) (β = 0.23, p = 0.001), and hsTnI (β = 0.27, p < 0.0001) (R2 = 0.49, F = 33.8, p < 0.0001). Correlations were found between a decrease in hsTnI and BNP in the first 3 months (ρ = 0.49, p < 0.0001). A decrease in FT4 in the first 3 months was weakly correlated with decreases in hsTnI (ρ = 0.32, p = 0.0004) and BNP (ρ = 0.32; p = 0.0003). Of the 27 patients with elevated hsTnI (≥5.0 pg/mL), the hsTnI level was normalized in 20 patients within a year. CONCLUSIONS In thyrotoxicosis, the myocardial biomarker hsTnI is elevated in about 20% of patients; hsTnI levels decrease as thyroid function improves and BNP decreases.

Abstract
An asymptomatic, 68-year-old Japanese man visited our hospital for further examination of subclinical hypothyroidism. At the first visit, the serum TSH level was markedly elevated (36.6 μIU/mL), but the serum level of free T4 was within the reference interval. Thyroid dysfunction due to dietary iodine excess was initially suspected. However, even after iodine restriction, his thyroid function tests were the same as at the first visit, which suggested false elevation of the TSH level. The TSH levels were compared among three different measurement systems, which showed a similar tendency of TSH elevation above the reference interval, but the different TSH elevation levels among the measurement methods suggested the existence of some interfering substance. Neither serial dilution of the patient's serum nor polyethylene glycol and protein G precipitation tests showed any significant changes in the recovery rate. IgG-bound macro-TSH was ruled out. The TSH peak on gel filtration chromatography was located at a molecular size greater than IgA, which suggested the presence of IgA-bound TSH. After precipitation with Jacalin, which binds specifically to IgA, the TSH level decreased from 30.7 μIU/mL to 2.01 μIU/mL, within the reference interval. Thus, IgA-bound macro-TSH was identified. Macro-TSH is a rare condition in which an immunoglobulin-bound, high-molecular-weight form of TSH results in a false elevation of the serum TSH level. When there is a discrepancy between the results of thyroid function tests and clinical symptoms, and macro-TSH is suspected, it is necessary to know that not only IgG-bound TSH but also IgA-bound TSH could be the cause.

Abstract
Background: The prognosis of Graves' disease (GD) is reportedly related to sex, age, and genetic factors, although there is no consensus. The objective of this study was to investigate the relationship between severity and prognosis of GD and sex or age. Methods: Subjects were patients newly diagnosed with GD between January 2005 and June 2019, and medical records were retrospectively reviewed. Patients diagnosed between January 2009 and December 2010 and followed up for at least 12 months were enrolled. Patients were divided into nine age-stratified groups. Remission was defined as maintenance of a euthyroid state for more than one year after withdrawal of antithyroid drugs (ATDs). Results: Participants comprised 21,633 patients (3954 males, 17,679 females). Initial free triiodothyronine (fT3) and free thyroxine (fT4) levels significantly decreased with increasing age, including after sex stratification. fT4 was significantly higher in males than females aged 20-39 years. In 2191 patients treated with ATDs alone, median durations until remission were 37.7 and 30.6 months in males and females, respectively. Remission and recurrence were observed in 1391 patients (204 males, 1187 females) and 262 patients (37 males, 225 females), respectively. By Kaplan-Meier analyses, males required a significantly longer time to achieve remission than females (p < 0.0001), although there were no significant age-related differences (p = 0.08). Cox proportional hazard modeling showed a 41% higher hazard ratio (HR) for remission in females than males (adjusted HRs [aHR] confidence interval [CI] = 1.41 [1.21-1.64]), and each additional 10 years of age had a 14% lower rate of recurrence (age [per 10-year increase], aHR [CI] = 0.86 [0.78-0.94]); no significant relationship between recurrence rate and sex was identified. Conclusions: Severity of hyperthyroidism in GD was significantly higher in males in their 20s and 30s, declining with advancing age in both sexes. Females were more likely to achieve remission than males, and younger patients had a higher risk of recurrence, although recurrence was unrelated to sex.

Abstract
Background: The indirect influence of the coronavirus disease 2019 (COVID-19) pandemic on clinical practice has received great attention. However, the evidence about how the pandemic has affected clinical management of hypothyroidism and hyperthyroidism, two common diseases worldwide, is lacking. We therefore aimed to examine the trends in the number of outpatients with thyroid disorders and their thyrotropin (TSH) levels before and during the pandemic in Japan. Methods: This cohort study included all patients aged ≥20 years who visited Ito Hospital, one of the largest hospitals that specialize in thyroid disorders in Japan, during 2019/1-2020/6. Our outcomes of interest were 1) trends in the aggregated number of visits at the clinic and 2) trends in average TSH levels from January 2019 to June 2020. The trends in TSH according to the clinic visit in early 2020 were assessed utilizing difference-in-difference models controlling for age, sex, and city of residence, stratified by each medication use (i.e., levothyroxine [LT4], antithyroid drug [ATD], potassium iodine [KI], or no medication). Results: During 2019/1-2020/6, we observed 517,412 visits at Ito Hospital for thyroid disorders, and the average number of visits per month was significantly decreased for both the first visits (1,995 in 2019 vs. 1,268 in 2020; reduction rate, 36%; p<0.001) and the follow-up visits (29,509 in 2019 vs. 21,959 in 2020; reduction rate, 26%; p<0.001). Among 15,455 patients who had been followed in 2019, we found a higher TSH at the follow-up visits during 2020/4-2020/6 among patients with LT4 who did not visit the clinic during 2020/1-2020/3 than those who did (difference-in-difference [95%CI]=+1.77 [1.25-2.29], p<0.001). We also found decreased trends in TSH among patients with ATD or KI who visited the clinic during 2020/1-2020/3 (p<0.001 for both categories), but not among patients with no medications (p=0.29). Conclusions: In this large cohort in Japan, we found the decreased number of outpatients with thyroid disorders since 2020/1 with a nadir in 2020/4. Using individual-level data, we also found the association between visiting the clinic in early 2020 and TSH control at the following visit among patients with medications. These findings highlight the importance of careful monitoring of patients with medications for thyroid disorders during the COVID-19 pandemic.

This study aims to investigate the prevalence of euthyroid individuals showing positive results for TRAb and to clarify the clinical course of thyroid function and TRAb levels in these subjects. Objective Subjects were female patients who newly visited our hospital for a screening test prior to fertility treatment and showed normal thyroid function and volume without nodules between 2014 and 2017. After excluding subjects with a history of thyroid disease, 5,622 subjects were analyzed. Results Forty-seven of the 5,622 subjects showed positive results for TRAb (reference range, <2.0 IU/L) at the initial visit. Median initial TRAb was 2.9 IU/L (range, 2.0-14.7 IU/L) and median follow-up was 18.3 months (range, 0-66.5 months). Six of the 47 subjects (12.8%) developed GD and median duration until development was 6.6 months (range, 1.2-13.2 months). Median TRAb values initially and at diagnosis of GD for those 6 patients were 3.7 IU/L (range, 2.7-5.1 IU/L) and 7.2 IU/L (range 3.6-21.4 IU/L), respectively. TRAb results turned negative for 20 of the 47 subjects but remained positive despite normal thyroid function in 13 of the 47 subjects. Conclusion GD developed over time in 12.8% of euthyroid young female patients showing positive TRAb within a median of 6.6 months. A positive result for TRAb itself did not mean development of GD, so other factors must be essential for the pathogenesis of GD.

Abstract
Context Medical treatment of Graves disease during the first trimester has been the subject of controversy ever since treatment with an antithyroid drug during the first trimester was reported to possibly be associated with an increased risk of birth defects in newborns. Objective We investigated whether the incidence of birth defects among newborns born to mothers with Graves disease (GD) treated with propylthiouracil (PTU) during the first trimester of pregnancy was higher than in a control group that was not exposed to any medication. Methods We reviewed the cases of 1913 women with GD who gave birth between January 1, 2015, and May 31, 2019. Detailed information concerning the outcome of pregnancy and the presence of birth defects was collected at the first visit after the delivery and again 1 year after delivery. We classified the mothers and infants into 3 groups according to the treatment the mother had received for GD in the first trimester of pregnancy: a group in which the mothers had been treated with PTU alone (PTU group), a group in which the mothers had not been treated with any medication (control group), and a group in which the mothers had received some other medical treatment, such as thiamazole, potassium iodide, or 2 or more drugs (other treatment group). Results The incidence of malformed infant births was 5.5% (30/541 infants) in the PTU group and 5.7% (27/ 475 infants) in the control group. There were no specific birth defects in the PTU group, and there were no significant differences between PTU dosages or maternal thyroid function according to whether mothers had delivered a child with a birth defect. Conclusion The results of our retrospective study showed that treatment with PTU during the first trimester of pregnancy did not increase the incidence of birth defects among newborns.

Abstract
Activity of Graves' disease (GD) is known to improve during gestation, as values of thyrotropin (TSH) receptor antibody (TRAb) also improve. However, the risk of neonatal hyperthyroidism increases when maternal TRAb values are high in the second to third trimester. A 29-year-old woman who had undergone radioactive iodine (RAI) therapy for GD 10 years earlier visited our hospital at 17 weeks of gestation, showing subclinical hypothyroidism and a positive TRAb value of 2.6 IU/L (reference range, <2.0 IU/L). Thyroid hormone replacement therapy was commenced and thyroid function normalized within 4 weeks, although TRAb was elevated at the time (3.8 IU/L). Prenatal check-up showed normal growth development and no irregularities. At 29 weeks of gestation, serum TRAb was extremely elevated, up to 16.8 IU/L. Since the risk of neonatal hyperthyroidism was of great concern, delivery was planned at an advanced-care medical center. At 38 weeks 5 days of gestation, she delivered a female neonate without any complications, although blood testing of the neonate showed subclinical hyperthyroidism with positive TRAb and TSH receptor stimulating antibody (TSAb). According to the American Thyroid Association guidelines, the TRAb value should be checked in the third trimester if mothers show a TRAb elevation between the initial visit after pregnancy and 18-22 weeks of gestation. However, if the mother has a history of RAI therapy for GD, regardless of thyroid function during gestation, the possibility of TRAb values elevating over time even years after the definitive therapy must be considered.

Abstract
Abstract
Background
Elder abuse is a serious public health concern that increases the risks of negative health outcomes globally. It is well known that abuse in older adults is associated with depression; however, longitudinal studies investigating the causal relationship between these events are scarce. Because the cause precedes the result over time, the temporal relationships between abuse and depression should be verified from each direction. This longitudinal study therefore investigated and clarified whether depression causes or results from elder abuse among older Japanese adults.
Methods
Two longitudinal analyses were conducted using data derived from the Japan Gerontological Evaluation Study. The data were collected in 2010 and 2013 through a mail survey of 1737 people (983 females, 754 males) across Japan.
Results
Of those who did not experience abuse in 2010, 38 (5.0%) males and 53 (5.4%) females newly experienced abuse in 2013. Among respondents who did not have depressive symptoms in 2010, 60 (8.0%) males and 61 (6.2%) females newly reported depressive symptoms in 2013. After adjusting for demographic factors in analysis 1, people who experienced abuse were 2.28-fold (95% confidence interval [CI] = 1.68-3.09) more likely to have depressive symptoms 3 years later than those who were not abused. In analysis 2, respondents who had mild or severe depression in 2010 were 2.23-fold (95% CI = 1.61-3.10) more likely to have experienced abuse after 3 years than those who did not have depression.
Conclusions
After adjusting for several demographic factors, the results showed that abuse can lead to depression and that depression can be a cause of abuse. Therefore, preventing abuse should be considered from both directions.
Key messages
Elder abuse could be a cause for depressive symptoms. Depressive symptoms could be a cause of elder abuse.

Abstract
The first description of well-preserved fur of one male and one female cubs of the fossil cave lion Panthera spelaea (finds of 2017-2018, Semyuelyakh River, Yakutia, Russia) is presented in comparison with the fur of two cubs (a male and a female) of the extant African lion P. leo and adult lions of both species: the color, differentiation, configuration, microstructure, and internal design of hair of different categories are considered. The coat of the cave lion is similar but not identical to that of the African lion, because it contains a high thick undercoat of spiral-shaped thick and airy down hair. This difference is most pronounced in the cave lion cubs, in which, however, the fur is not differentiated to the same extent as in the adult. The microstructure of hair is species-specific and subject to intraspecific age-related variability. Adaptive features of the hair structure in the cave lion are noted.

Abstract
The efficacy of potassium iodide (KI) for Graves' disease (GD) has been reported, although few clinical reports have examined the long-term efficacy of treatment. The objective of this study was to investigate the efficacy and limitations of KI treatment for GD. This study enrolled patients newly diagnosed with mild GD, defined as free thyroxine (FT4) <5.0 ng/dL, between July 2014 and June 2016. KI was started at a dose of 50 mg/day, and if FT4 values did not decrease after initiation of treatment, doses were increased to 100 mg/day. Patients for whom thyroid hormone levels could not be controlled with KI at 100 mg/day were regarded as non-responders. Of the 122 patients (13 males, 109 females) included in this study, 71 (58.2%) responded to KI therapy. The remaining 51 patients (41.8%) were non-responders. The median duration required to judge non-responsiveness was 5.9 months. Multiple logistic regression analysis performed on parameters measured at the initial visit indicated FT4 (odds ratio (OR) 2.19, 95% confidence interval (CI) 1.28-3.75; p = 0.0007) and male sex (OR 3.58, 95%CI 1.04-12.3; p = 0.04) were significantly associated with KI responsiveness. Receiver operating characteristic (ROC) curve analysis of the relationship between FT4 and KI responsiveness indicated an FT4 cut-off of 2.76 ng/dL was optimal for differentiating between responders and non-responders. KI therapy was effective and safe for about 60% of patients with mild GD.

Abstract
Background: The clinical course of Graves' disease (GD) in women who switched from methimazole (MMI) to potassium iodide (KI) during the first trimester of pregnancy has never been reported in detail. Objective: To investigate the characteristics of GD patients whose thyroid hormone levels increase after substituting KI for MMI. Patients: Two hundred forty women with GD who had been treated with MMI and switched from MMI to inorganic iodide to control hyperthyroidism during the first trimester between January 1, 2005, and March 31, 2018. Results: In 133 (55.4%) of the GD patients, medication was completely tapered during pregnancy, and the other 107 (44.6%) GD patients were taking medication at delivery: 57 were taking KI alone and 50 were taking an antithyroid drug with or without KI. It was difficult to control the maternal thyrotoxicosis of 22 of the 107 patients with KI alone, and a higher dose of MMI compared with the dose at the time of conception was required (worsened group). Multivariate analysis revealed that the TRAb value at the time of switch from MMI to KI was the only factor that predicted continuation of the thyroid suppression medication, but none of the parameters was a predictor of the worsened group. Conclusions: It must be kept in mind that a certain proportion of GD patients escape from the antithyroid effect of iodide and that careful follow-up is necessary after switching a pregnant patient's medication to KI.

Abstract
Abstract
Background
It has been thought BNP is induced by undetermined stretch-activated receptors, however, which receptor is associated remains unknown. The stretch-activated receptors include mechanically gated channels, which can be activated by a mechanical stimulus alone, and mechanically modulated channels, which require nonmechanical stimuli such as agonists. It has been recently shown that 1.1kb segment of mouse NPPB promoter dose not reproduce the pattern of reactivation of BNP in adult heart, although it could monitor the expression of BNP in neonatal cardiomyocytes.
Purpose
Our aim is to develop a true BNP reporter mouse and examine whether this mouse is useful or not for the investigation of BNP reactivation mechanism in adult heart and for the measurement of serum-induced BNP expression in patients with heart failure.
Methods
We generated the BNP reporter mice by knocking luciferase cDNA in the initiation site of NPPB. In vivo imaging of luciferase was performed in the BNP reporter mice after the intraperitoneal injection of luciferin. The luciferase activity was examined in neonatal cardiomyocyte, isolated adult cardiomyocytes, adult cardiac dissected tissue with or without 120–150% stretch or angiotensin II stimulation. Left anterior descending (LAD) coronary artery was ligated to study myocardial infarction. Cardiac dissected tissue segments from the BNP reporter mouse were incubated for 8 hours with 20% serum from patients with or without heart failure and the luciferase activity was measured after homogenization.
Results
The in vivo imaging system showed the activity of BNP was high in 1 day-old neonates and the reactivation of BNP in the adult heart after LAD ligation could be monitored by the luciferase activity (figure). The treatment of Ang II could increase the activity of pBNP more than ten folds in heart tissue from adult mice. On the other hand, the 120–150% stretch did not show any effect on the activity of pBNP in this system. We could not observe any activation of pBNP in cultured neonatal or adult cardiomyocytes demonstrated by immunostain with antibodies against luciferase after 120–150% stretch. Interestingly, the luciferase activity was extensively higher in cultured heart tissue segments from the BNP reporter mice after the treatment of serum from patients with heart failure than without heart failure.
In vivo imaging of BNP reporter mice
Conclusion
These results indicate the BNP reporter mouse by knock-in technology is useful for the analysis of mechanism in reactivation of BNP in adult heart and the elevation of BNP in patients of heart failure partly due to the serum-derived induction of BNP from heart.

Abstract
Background: The prevalence of antithyroid drug (ATD)-related drug-induced liver injury (DILI) has been reported to vary among patients in several countries. The purpose of this study was to summarize the prevalence of liver injury induced by ATD and to determine the actual prevalence of severe liver injury. Methods: The medical records of 18,558 patients who were newly diagnosed with Graves' disease between January 2005 and December 2016 were retrospectively reviewed. Severe DILI was defined as alanine aminotransferase (ALT) 8 times higher than the upper limit of normal (ULN) or total bilirubin (T-bil) 3 times higher than the ULN. The most severe DILI was defined as ALT higher than 20 times the ULN or T-bil higher than 10 times the ULN. Results: A total of 461 subjects (470 cases) were analyzed, and they consisted of 10 males and 451 females, with a median age of 37 years (range 10-82 years). Nine of 461 patients had severe DILI with both drugs. The total prevalence of severe DILI in this study was 2.5%, and the prevalence of DILI by drug was 1.4% with metimazole (MMI) (n = 198) and 6.3% with propylthiouracil (PTU) (n = 272) (p < 0.001). The prevalence of the most severe ATD-related DILI was 0.22% (n = 40), and the prevalence for each drug was 0.08% with MMI (n = 11) and 0.68% with PTU (n = 29). The median time to DILI development was 30 days (range 7-314 days), and all patients recovered from DILI, with no fatalities. The prevalence of MMI-related DILI was significantly age dependent (p < 0.001). Conclusions: Though there were no fatalities in this study, the prevalence of PTU-related severe DILI was significantly higher than that of MMI-related severe DILI.

Evaluation of an early-stage innovation for full-thickness excision of benign colonic polyps using the IDEAL framework. Colorectal Dis 2019; 21:1004-1016.

Abstract
AIMS Colectomy is the current approach for patients with endoscopically unresectable benign polyps but risks considerable morbidity. Full-thickness laparoendoscopic excision (FLEX) is a novel procedure, specifically developed to treat endoscopically unresectable benign colonic polyps, which could reduce the treatment burden of the current approach and improve outcomes. However, traditional evaluations of surgical innovations lack methodological rigour. This study reports the development and feasibility of the FLEX procedure in selected patients. METHOD A prospective development study using the Idea, Development, Evaluation, Assessment, Long-term study (IDEAL) framework was undertaken, by one surgeon, of the FLEX procedure in selected patients with endoscopically unresectable benign colonic polyps. Three-dimensional (3D)-CT colonography reconstructions were used preoperatively to rehearse patient-specific, critical manoeuvres. Targetted, full-thickness excision was performed: after marking the margin of the caecal polyp using circumferential endoscopic argon plasma coagulation, transmural endoscopic sutures were used to evert the bowel and resection was undertaken by laparoscopic linear stapling. Feasibility outcomes (establishing 'local success') included evidence of complete polyp resection without adverse events (especially safe closure of the excision site). RESULTS Ten patients [median (interquartile range) age: 74 (59-78) years] with polyp median diameters of 35 (30-41) mm, were referred for and consented to receive the FLEX procedure. During the same time frame, no patient underwent colectomy for benign polyps. One further patient received FLEX for local excision of a presumed malignant polyp because severe comorbidity prohibited standard procedures. The FLEX procedure was successfully performed locally, with complete resection of the polyp and safe closure of the excision site, in eight patients. Three noncompleted procedures were converted to laparoscopic segmental colectomy under the same anaesthetic because of endoscopic inaccessibility (two patients) and transcolonic suture failure (one patient). CONCLUSIONS The FLEX procedure is still under development. Early data demonstrate that it is safe for excision of selected benign polyps. Modifications to transcolonic suture delivery are now required and there is a need for wider adoption before more definitive evaluation can be performed.

Abstract
BACKGROUND AND PURPOSE Tapering immunosuppressants is desirable in patients with well-controlled myasthenia gravis (MG). However, the association between tapering of calcineurin inhibitor dosage and reduction-associated exacerbation is not known. The aim of this study was to clarify the frequency of reduction-associated exacerbation when tacrolimus is tapered in stable patients with anti-acetylcholine receptor antibody-positive MG, and to determine the factors that predict exacerbations. METHODS We retrospectively analyzed 115 patients in whom tacrolimus dosage was tapered. The reduction-associated exacerbation was defined as the appearance or worsening of one or more MG symptoms <3 months after the reduction. RESULTS Tacrolimus dosage was successfully tapered in 110 patients (96%) without any exacerbation. Five patients (4%) experienced an exacerbation, but symptoms were reversed in all patients when the tacrolimus dose was increased to the previous maintenance level. No patient developed an MG crisis. The age at onset was significantly earlier (30 vs. 56 years, P = 0.025) and the reduction in dosage was significantly larger (2.0 vs. 1.0 mg/day, P = 0.002) in patients with reduction-associated exacerbation than in those without exacerbation. The cut-off values determined in a receiver-operating characteristic curve analysis were 52 years (sensitivity, 57%; specificity, 100%) for the age at onset and 1.5 mg (sensitivity, 80%; specificity, 100%) for the dose reduction. CONCLUSION Tapering of tacrolimus was possible in most patients with well-controlled anti-acetylcholine receptor antibody-positive MG. Early age at onset and a large reduction from maintenance dosage were associated with exacerbation. Reductions ≤1.5 mg/day from the maintenance dosage should be considered for patients with late-onset disease.

Abstract
BACKGROUND The serum thyrotropin receptor antibody (TRAb) titers of Graves' disease (GD) patients are known to increase after radioiodine (RAI) therapy, and they can remain high for years. The incidence of neonatal hyperthyroidism (NH) among newborns of mothers with GD who conceived after RAI therapy has not been previously reported. The aims of this study were to investigate the incidence of NH among newborns of mothers who conceived within two years after RAI therapy, and to identify predictors of NH. METHODS GD patients (n = 145) who conceived within two years after RAI therapy were retrospectively reviewed, and information regarding their newborns was collected. RESULTS Of the 145 pregnant women, 54 (37%) were treated with antithyroid drugs or potassium iodide for maternal hyperthyroidism during the first trimester. There were eight newborns with NH, resulting in an incidence of 5.5%. Seven of the eight mothers whose newborns had NH were treated with antithyroid drugs or potassium iodide during their pregnancy. The incidence of NH among the newborns of mothers who conceived within 6-12 months after RAI therapy was 8.8%, within 12-18 months was 5.5%, and within 18-24 months was 3.6%. Multivariate analysis revealed that the TRAb values in the third trimester were the only risk factor for NH. The cutoff TRAb value in the third trimester for predicting NH was 9.7 IU/L (reference value <2.0 IU/L). CONCLUSIONS The incidence of NH among newborns of mothers who conceived within two years after RAI therapy was 5.5%. The fetuses of pregnant GD patients whose TRAb value is high in the third trimester should be carefully followed by an obstetrician during pregnancy, and the newborns should be carefully followed by a pediatrician after birth.
