RESUMO

Underreporting is a problem in dietary surveys, and data on Japanese individuals with obesity are lacking. In addition, in dietary surveys of individuals with obesity, underreporting and extreme energy restrictive practices for short periods of time have been reported, and blood total ketone levels (ketone bodies) may be able to distinguish between these factors. The present study aimed to examine the relationship between underreporting [energy intake (EI)/basal metabolic rate estimate (BMR)] and ketone bodies in obese Japanese women. The participants included 91 women with obesity aged 47±9 years with a body mass index (BMI) of 29.8±3.9 kg/m² who met the exclusion criteria out of 164 individuals who participated in an institutional cohort study baseline survey between September 2006 and September 2015. The current study defined the relationship between EI/BMR, BMI and the participants' ketone body levels. EI/BMR <1.35 and ketone body level <1.0 mmol/l was defined as underreporters, while EI/BMR <1.35 and ketone body level ≥1.0 mmol/l was defined as energy-restricted reporters based on previous research. The EI/BMR of the participants was 1.44±0.32, and 25.3% had an abnormally high level of ketone bodies. Multiple regression analysis indicated that ketone bodies were explanatory variables for EI/BMR. Analysis using EI/BMR and ketone bodies estimated that 26.4% were underreporters and 12.1% were energy-restricted reporters. There were no significant differences in reported energy intake, carbohydrate intake (g/day), and percentage carbohydrate (%) between the underreporters and energy-restricted reporters. In conclusion, low EI/BMR was associated with high ketone body levels in Japanese women with obesity. The combination of EI/BMR and ketone bodies may distinguish between or screen for underreporters and energy-restricted reporters during a dietary survey.

RESUMO

BACKGROUND: Vitamin D deficiency (VDD) is associated with an increased risk for lifestyle-related diseases. In Japan, VDD is quite prevalent in all age groups, with its high risk in young women. Furthermore, its association during pregnancy with gestational hypertension and low birth weight has also been reported. VDD can be diagnosed by serum 25-hydroxyvitamin D [25(OH)D] levels, which, however, is not suited for screening. Therefore, we will create a predictive model for serum 25(OH)D concentration and prevalence of VDD based on such data as region, sun exposure habit, and vitamin D intake in young women. METHODS: From 2020 to 2022, we conduct a cross-sectional study of 600 young women in four regions of Japan, identify the indices associated with serum 25(OH)D concentrations such as sun exposure habits, habitual vitamin D intake, ultraviolet-B irradiation, seasons (summer and winter) and latitude, and construct prediction models for serum 25(OH)D concentrations and VDD risk. This study has been registered with UMIN-CTR (ID: UMIN000041527). RESULTS: One hundred and fifteen subjects have been collected from 6 institutions in winter as of May 2021. When data from more than 200 subjects have become available, we will conduct the interim analysis, summarize the data by region and facility, review the inclusion criteria for analysis, and check for missing values and outliers. Prediction models for serum 25(OH)D concentration and VDD will be determined in the final analysis when all cases have been collected. CONCLUSIONS: A screening tool for VDD risk to be developed in our study based on the predictive model would help the public and medical professionals prevent lifestyle-related diseases through improving VDD. Additionally, the results may serve as the scientific basis for determining the appropriate vitamin D intake and sun exposure standards.

RESUMO

BACKGROUND: No study has previously investigated insulin resistance in collegiate baseball players. The purposes of this study were to examine: 1) the insulin resistance; and 2) the usefulness of the adiponectin/leptin (A/L) ratio compared with the homeostasis model assessment of insulin resistance (HOMA-IR) for assessing insulin resistance in collegiate baseball players. METHODS: Twenty collegiate baseball players with abdominal obesity (AO group) defined by a waist circumference (WC) ≥85 cm, 65 lean baseball players with a WC<85 cm (L group), and 20 controls who were sedentary for at least 1 year (C group) were compared. The Body Mass Index, WC, systolic and diastolic blood pressures, fasting plasma glucose, total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, apolipoprotein B, insulin, leptin, adiponectin, and high-sensitivity C-reactive protein (hs-CRP) were measured. RESULTS: The AO group had a significantly higher insulin level, HOMA-IR, and leptin level, and lower A/L ratio than the L and C groups. The AO group had a significantly higher prevalence of insulin resistance (50%) than the L (14%) group. The A/L ratio was significantly negatively correlated with body weight, Body Mass Index, WC, triglycerides, triglycerides/HDL-C ratio, apolipoprotein B, hs-CRP, insulin, HOMA-IR, and leptin, and positively correlated with HDL-C, whereas HOMA-IR was significantly positively correlated with body weight, Body Mass Index, WC, systolic and diastolic blood pressures, fasting plasma glucose, and insulin, and negatively correlated with adiponectin and the A/L ratio. In the forward stepwise multiple regression analysis, WC, triglycerides, and hs-CRP were the significant determinants for the A/L ratio, whereas diastolic blood pressure and WC were the significant determinants for HOMA-IR. This model explained 53.7% of the variance in the A/L ratio and 13.6% of the variance in HOMA-IR. CONCLUSIONS: The present study suggested that the baseball players with abdominal obesity had a significantly higher prevalence of insulin resistance than the lean baseball group. The A/L ratio may be more useful than HOMA-IR to accurately assess insulin resistance in male collegiate baseball players.

RESUMO

CONTEXT: Pheochromocytoma (PHEO) and paraganglioma (PGL) (PHEO and PGL: PPGLs), catecholamine-producing tumors, represent an emerging cause of secondary osteoporosis. However, despite decreased bone mineral density (BMD), vertebral fracture (VF) is not associated with BMD in PPGLs. OBJECTIVE: To evaluate whether deteriorated bone quality is involved in the development of osteoporosis in PPGLs. PARTICIPANTS: Trabecular bone score (TBS), used to assess trabecular bone quality, was examined in 56 patients with PPGLs and 52 with non-functional adrenal tumors (AT). Radiograph of the spine was carried out in 35 patients with PPGLs, and TBS was analyzed in 18 patients with PPGLs at follow-up. MAIN OUTCOME MEASURE: TBS and BMD at the lumbar spine in patients with PPGLs with and without VF. RESULTS: PPGLs had a lower TBS (n = 56, 1.338 [1.294-1.420]) than non-functional AT (n = 52, 1.394 [1.342-1.444]; p = 0.033). Among those with PPGLs, patients with VF (n = 14, 1.314 [1.289-1.346]) had a lower TBS than those without VF (n = 21, 1.383 [1.324-1.426]; p = 0.046), despite no significant difference in BMD at the lumbar spine between the two groups (p = 0.501). An optimal cut-off level of TBS for diagnosing VF in PPGLs was 1.323, and its area under the curve was 0.702. The severity of catecholamine excess and maximal size of tumor were associated with decreased TBS in PPGLs patients (p = 0.016 and p = 0.020, respectively). Surgical resection of PPGLs improved TBS at follow-up, with 2.5% increase (p = 0.007). CONCLUSIONS: This study provides evidence for the importance of deteriorated bone quality rather than decreased bone mass in the development of VF in PPGLs.

RESUMO

We aimed to clarify food intake and dietary patterns that affect urinary sodium excretion (urinary salt excretion) among young women. We used 2012 to 2018 data from the health and nutrition testing on admission, which is a part of ongoing epidemiological studies, for students enrolling in the Faculty of Nutrition Science, Nakamura Gakuen University. Fasting urine samples were collected from the participants, and their estimated daily salt excretion was calculated using the Tanaka equation. The dietary assessment used was the semi-quantitative food frequency questionnaire, and we confirmed its validity. The participants included 2218 women aged 18 to 20 years who were classified into four groups according to urinary salt excretion (g/d) from their spot urine: Q1 , <5.56; Q2 , 5.56≤, <6.79; Q3 , 6.79≤, <8.12; and Q4 , 8.12<. The high urinary salt group had a significantly higher consumption of oil and fat, fish, meat, eggs, soybean, green and yellow vegetables, white vegetables, seaweeds, and pickled vegetables compared with the low urinary salt groups. When we compared the differences of the quartiles for urinary sodium excretion and the factor loadings for three dietary patterns by factor analysis with varimax rotation, the high urinary salt group showed a higher tendency for Japanese dietary patterns of factor 1 compared with the low urinary salt group. In conclusion, the various foods, including foods containing proteins and vegetables and Japanese dietary pattern centering on fish, vegetables, soybeans, and seaweed, affected the urinary sodium excretion in young women.

RESUMO

CONTEXT: Pheochromocytoma (PHEO) and paraganglioma (PGL) (PHEO and PGL: PPGLs) are catecholamine-producing neuroendocrine tumors, which are known to be associated with low bone mineral density (BMD). However, it remains unknown whether PPGLs are associated with high prevalence of osteoporotic fracture and if so, whether their surgical resection improves BMD has been addressed. OBJECTIVE: To evaluate the risk of vertebral fracture (VF) in PPGLs and the improvement of BMD after surgery. DESIGN AND SETTINGS: A retrospective cross-sectional study in a single referral center. PARTICIPANTS: This study included the following patients: 1) 49 patients with PPGLs and 61 patients with non-functional AT who were examined radiograph of the spine, 2) 23 patients with PPGLs who were examined BMD at follow-up. INTERVENTION: 1) The prevalence of VF was evaluated between PPGLs and non-functional AT. 2) In PPGLs, BMD was evaluated at baseline and after surgery. RESULTS: PPGLs had a higher prevalence of VF (43% [21/49]) than non-functional AT (16% [10/61]; p = 0.002). PPGLs were associated with VF after adjusting for age and sex (odds ratio, 4.47; 95% confidence interval, 1.76-11.3; p = 0.001). In PPGLs, BMD at the lumber spine was improved (before: 0.855 ± 0.198 g/cm2, after: 0.888 ± 0.169 g/cm2, mean of the difference: 0.032 g/cm2, p = 0.026), with 3.8% increase. CONCLUSION: This study demonstrates that PPGLs was associated with VF and that their surgical resection contributes to the improvement of BMD in the trabecular bone. These observations support the notion that PPGLs are an emerging cause of secondary osteoporosis.

RESUMO

New diagnostic criteria and the treatment policy for adrenal subclinical Cushing's syndrome (SCS) are proposed on behalf of the Japan Endocrine Society. The Japanese version has been published, and the essential contents are presented in this English-language version. The current diagnostic criteria for SCS have elicited two main problems: (i) the relatively low reliability of a low range of serum cortisol essential for the diagnosis by an overnight 1-mg dexamethasone suppression test (DST); (ii) different cutoff values for serum cortisol after a 1-mg DST compared with those of other countries. Thus, new criteria are needed. In the new criteria, three hierarchical cortisol cutoff values, 5.0, 3.0 and 1.8 µg/dL, after a 1-mg DST are presented. Serum cortisol ≥5 µg/dL after a 1-mg DST alone is considered sufficient to judge autonomous cortisol secretion for the diagnosis of SCS, and the current criterion based on serum cortisol ≥3 µg/dL after a 1-mg DST can continue to be used. Clinical evidence suggests that serum cortisol ≥1.8-2.9 µg/dL after a 1-mg DST is not always normal, so cases who meet the cutoff value as well as a basal adrenocorticotropic hormone (ACTH) level <10 pg/mL (or poor ACTH response to corticotropin-releasing hormone (CRH)) and nocturnal serum cortisol ≥5 µg/dL are proposed to have SCS. We suggest surgery if cases show serum cortisol ≥5 µg/dL after a 1-mg DST (or are disheartened by treatment-resistant problems) or suspicious cases of adrenal cancer according to tumor imaging.

RESUMO

The authors investigated interannual differences in the sodium excretion levels of young healthy Japanese women as estimated from spot urine analysis at Nakamura Gakuen University from 1995 to 2015. Participants included 4931 women aged 18 to 20 years who were classified into three time periods according to year of health check: first (1995-2001), second (2002-2007), and third (2008-2015). Estimated daily urinary sodium and potassium excretion levels and the sodium to potassium ratio were 120.6±31.9 mmol, 35.2±8.1 mmol, and 3.5±0.9, respectively. Adjusted for body weight, sodium excretion, and potassium excretion significantly decreased in the second and third period compared with the first period (P<.001). Systolic blood pressure also decreased in the same way between time periods (P<.001). Estimated urinary excretion levels of sodium and potassium in young Japanese women have decreased over the past 20 years independently of body weight.

RESUMO

Primary aldosteronism (PA) is associated with a higher rate of cardiovascular events than essential hypertension. Although adrenalectomy has been reported to reduce carotid intima-media thickness (IMT) in patients with PA, the effects of the selective aldosterone blocker, eplerenone, on vascular damage in these patients remains unclear. To evaluate the effects of eplerenone on vascular status in PA patients, we sequentially measured carotid IMT (using computer software to calculate an average IMT for accurate and reproducible evaluation) in 22 patients including 8 patients treated by unilateral adrenalectomy and 14 patients treated with eplerenone for 12 months. Patients who underwent adrenalectomy showed significant reductions in aldosterone concentration (from 345 ± 176 pg/mL to 67 ± 34 pg/mL; P<0.01) and IMT (from 0.67 ± 0.07 mm to 0.63 ± 0.09 mm; P<0.05) 6 months after surgery. Patients treated with eplerenone showed significant reductions in IMT from baseline (0.75 ± 0.10 mm) to 6 (0.71 ± 0.11 mm; P<0.05) and 12 (0.65 ± 0.09 mm; P<0.01) months, although plasma aldosterone level increased significantly, from 141 ± 105 pg/mL to 207 ± 98 pg/mL (P<0.05). Eplerenone treatment of patients with PA reduces blood pressure, increases serum potassium level, and improves vascular status. Carotid IMT may be a useful marker for evaluating the effectiveness of eplerenone in patients with PA.

RESUMO

Anaplastic thyroid carcinoma (ATC) although rare is the most lethal form of thyroid cancer. The mortality rate for ATC is very high, with a median survival time of only 5 months; the survival rate at 1 year after diagnosis is <20%. Management of ATC is extremely difficult and rife with uncertainties. Herein, we describe a 75-year-old woman who presented with ATC and was successfully treated using concomitant treatment with docetaxel and high-dose radiotherapy. This case appears to be the first to have been reported in the literature involving complete remission of ATC confirmed by autopsy, suggesting the therapeutic potential of this combination.

RESUMO

Subclinical Cushing's syndrome (SCS) is characterized by subtle autonomous cortisol secretion from adrenal tumors without specific signs and symptoms of hypercortisolism. Patients with SCS have a high prevalence of "lifestyle-related diseases," such as hypertension, diabetes mellitus, dyslipidemia, and osteoporosis. Long-term follow-up of SCS patients is reportedly indispensable for establishing indications for surgical treatment of SCS. We performed a follow-up survey of 27 patients with SCS (median: 5.3 years) and compared those who had undergone surgical treatment (n=15) with those who had not (n=12). The mean diameter of tumors was 31 mm; 16 (59%) patients had unilateral lesions and 11 (41%) carried bilateral ones. In 67% and 60% of the treatment group, respectively, hypertension and diabetes mellitus improved. We also noticed that eight of 11 (73%) SCS patients with bilateral adrenal tumors had extra-adrenal malignancies in various tissues. Interestingly, among nine SCS patients who had malignancies, eight showed bilateral adrenal uptake in ¹³¹I-aldosterol scintigraphy. The results imply that surgical treatment can reduce cardiovascular risks in SCS patients. Screening for malignancy may be necessary in patients with bilateral adrenal tumors suspected of autonomous hypersecretion of cortisol from both sides.

RESUMO

Surgical treatment of pheochromocytoma is associated with a high risk of hemodynamic instability. To reduce the risk of perioperative complications, adequate medical treatment to normalize blood pressure and restore blood volume is required. Accurate evaluation of the circulating blood volume (CBV) in perioperative patients with pheochromocytoma is clinically important. In the present study, we adopted whole-body bioimpedance monitoring technique using the Non-Invasive Cardiac System (NICaS), which can non-invasively measure cardiac output (CO) values. NICaS-derived CO values were evaluated in eight preoperative patients with pheochromocytoma and were compared with simultaneous CBV values measured by a conventional indicator dilution method using (131)I-labeled human serum albumin. In these patients with pheochromocytoma, the NICaS-derived CO values were significantly correlated with the CBV values measured by (131)I-labeled human serum albumin (4.86 ± 1.05 L/min vs 4.79 ± 1.02 L; r = 0.906; P = 0.002). Sequential NICaS-derived CO values confirmed that CBV increased after preoperative treatment with an α-blocker, with or without volume loading. The results of this study indicate that NICaS can be used to accurately and non-invasively evaluate the hemodynamic status. By sequential monitoring of NICaS-derived CO values, we are able to confirm whether adequate CBV in a patient with pheochromocytoma is obtained by preoperative medical treatment with α-blockers or volume loading, to avoid perioperative complications.

RESUMO

Eldecalcitol (1α, 25-dihydroxy-2ß-[3-hydroxypropyloxy] vitamin D3; ED-71) is a new analog of the active form of vitamin D. Eldecalcitol has recently been approved for the treatment of osteoporosis in Japan. In addition to regulation of calcium metabolism carried out by conventional vitamin D analogs, eldecalcitol possesses a strong inhibitory effect on bone resorption and causes a significant increase in bone mineral density. A Phase III clinical trial on osteoporosis showed that eldecalcitol reduced the incidence of new vertebral fractures over 3 years by 26% compared with alfacalcidol. Although the overall risk of nonvertebral fractures was not reduced by eldecalcitol, the risk of wrist fracture was decreased significantly in the eldecalcitol group (71%) compared with the alfacalcidol group. The serum level of 25-hydroxyvitamin D (25[OH]D) was normalized by supplementation of native vitamin D in this trial, so the desirable effects on bone by eldecalcitol were considered to be derived from its distinctive pharmacological action. Increased blood calcium was observed in 21% of patients treated with eldecalcitol, and hypercalcemia (>11.5 mg/dL) occurred in 0.4% of eldecalcitol recipients, so serum calcium concentration should be monitored after starting eldecalcitol treatment. Eldecalcitol has dual effects on the metabolism of bone and calcium and is useful for the treatment of osteoporosis, especially for elderly patients (who frequently suffer from vitamin D deficiency). This article reviews the clinical efficacy and safety of eldecalcitol in the treatment of osteoporosis.

RESUMO

BACKGROUND: A considerable interest has been drawn to potential protective effects of bilirubin against oxidative stress-related diseases. Smoking is known to be associated with lower concentrations of serum bilirubin, but other behavioral correlates of serum bilirubin have not been well studied. In this cross-sectional study, we examined the associations of behavioral and clinical factors with serum total bilirubin in Japanese men and women. METHOD: The study subjects comprised of 4802 men and 6414 women aged 49-76 years who participated in the baseline survey of an ongoing cohort study on lifestyle-related diseases in Fukuoka, Japan. With consideration to time of the day of blood sampling and fasting hours, the associations with smoking, alcohol intake, body mass index, physical activity, coffee, tea, blood pressure, glycated hemoglobin (HbA1c), HDL cholesterol and non-HDL cholesterol with serum bilirubin were evaluated by analysis of covariance and multiple linear regression analysis. RESULTS: While smoking was negatively associated with serum bilirubin, alcohol consumption was positively associated with serum bilirubin in both men and women. Coffee consumption was associated with lower bilirubin concentrations in both sexes. In the multiple linear regression analysis, HDL cholesterol was positively and HbA1c was negatively associated with bilirubin in both men and women, and the associations were more evident in women. CONCLUSION: Smoking, alcohol use and coffee consumption were important behavioral correlates of serum bilirubin in Japanese men and women. Serum HDL cholesterol was a measurable clinical correlate of bilirubin in women.

RESUMO

Subclinical Cushing's syndrome (SCS) associated with adrenal incidentaloma is usually characterized by autonomous cortisol secretion without overt symptoms of Cushing's syndrome (CS). Although the diagnostic criteria for SCS differ among countries, the 1 mg dexamethasone suppression test (DST) is essential to confirm the presence and the extent of cortisol overproduction. Since 1995, SCS has been diagnosed in Japan based on serum cortisol levels ≥3 µg/dL (measured by radioimmunoassay [RIA]) after a 1 mg DST. However, the increasing use of enzyme immunoassays (EIA) instead of RIA has hindered the diagnosis of SCS because of the differing sensitivities of commercially available assays, particularly for serum cortisol levels of around 3 µg/dL. One way to overcome this problem is to lower the cortisol threshold level after a 1 mg DST. In the present study, we examined the clinical applicability of lowering the cortisol threshold to 1.8 µg/dL, similar to the American Endocrine Society's guidelines for CS, by reanalyzing 119 patients with adrenal incidentaloma. Our findings indicate that serum cortisol levels ≥1.8 µg/dL after 1 mg DST are useful to confirm the diagnosis of SCS if both of the following criteria are met: (1) basal ACTH level <10 pg/mL (or poor plasma ACTH response to corticotrophin-releasing hormone) and (2) serum cortisol ≥5 µg/dL at 21:00 to 23:00 h. If only one of (1) and (2) are met, we recommend that other clinical features are considered in the diagnosis of SCS, including serum dehydroepiandrosterone sulfate levels, urine free cortisol levels, adrenal scintigraphy, and clinical manifestation.

RESUMO

In patients with acromegaly, cardiovascular diseases are the most common cause of death. Arterial stiffness is increasingly recognized as a valuable surrogate marker for predicting cardiovascular events. To evaluate the vascular status of acromegalic patients, we used the cardio-ankle vascular index (CAVI) to reflect the arterial stiffness from the heart to the ankles. We analyzed 21 acromegalic patients, comprising five patients with untreated active acromegaly, one patient treated with medication and 15 patients who underwent transsphenoidal surgery. Among the 15 patients with surgery, 10 received additional therapies with dopamine agonists and/or somatostatin analogs. All patients with acromegaly unexpectedly showed significant reductions in the CAVI, indicating reduced arterial stiffness, compared with age- and sex-matched controls, regardless of whether they underwent surgery. There was a significant negative correlation between the CAVI and the serum insulin-like growth factor (IGF)-I level in these patients. Active acromegalic patients were associated with lower CAVI than controlled patients. Sequential measurements of the CAVI and serum IGF-I before and after treatment with octreotide and transsphenoidal surgery revealed that a reduced IGF-I level after treatment was accompanied by CAVI elevation. The present findings indicate that the CAVI is negatively correlated with the serum IGF-I level in acromegaly. These findings are consistent with previous reports indicating that the GH/IGF-I axis reduces peripheral vascular resistance. This non-invasive assessment can reflect the present vascular status and would be a useful marker for evaluation of therapeutic effects in patients with acromegaly.

RESUMO

BACKGROUND: Inflammation has been implicated in the pathogenesis of cardiovascular disease, type 2 diabetes mellitus and cancer. Serum concentration of high-sensitivity C-reactive protein is a good biomarker of chronic low-grade inflammation. Few studies have evaluated relative importance of behavioral and clinical covariates of high-sensitivity C-reactive protein in Japanese population. METHODS: The study subjects were men and women aged 49-76 years from the cohort study of lifestyle-related diseases between February 2004 and July 2006. Analysis of covariance and multiple linear regression analysis were used to estimate geometric means of high-sensitivity C-reactive protein and trends of association. RESULTS: Smoking, body mass index, hypertension, type 2 diabetes mellitus, elevated non-high density lipoprotein cholesterol, prudent dietary pattern were independently associated with serum high-sensitivity C-reactive protein in both men and women. High-sensitivity C-reactive protein concentrations were lowest in men with a moderate intake of alcohol (<30 mL/day). In men, smoking and body mass index accounted for 28% and 26% of the variation in high-sensitivity C-reactive protein, respectively, while body mass index accounted for 60% of the variation of high-sensitivity C-reactive protein in women. CONCLUSIONS: Smoking and body mass index in men, and body mass index in women, were major correlates of serum high-sensitivity C-reactive protein in Japanese people.

RESUMO

Pheochromocytoma crisis is a life-threatening endocrine emergency associated with symptoms of excess release of catecholamines. It might present spontaneously or be unmasked by triggers including trauma, surgery and certain medications that provoke catecholamine release by tumors. Here we report a case of pheochromocytoma crisis associated with abscess formation in the tumor and bacteremia of Campylobacter fetus, which was successfully treated with antibiotics and a surgical resection. This case appears to be the first reported case in the literature of abscess formation by C. fetus in pheochromocytoma, leading to catecholamine crisis.
