Hyperinsulinemia and thyroid peroxidase antibody in Chinese patients with papillary thyroid cancer.

This study aimed to investigate if hyperinsulinemia and/or insulin resistance was correlated with the occurrence of papillary thyroid cancer (PTC) in a group of Chinese patients. 258 inpatients were included in the study. According to the postoperative pathology results, all subjects were divided into PTC (n = 153) and control groups (with benign thyroid nodules, n = 105). Body mass index (BMI), fasting glucose, fasting insulin, homeostasis model assessment of insulin resistance (HOMA-IR), thyroid-stimulating hormone (TSH), FT4, FT3, thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TGAb), serum uric acid (UA), and lipid levels. Fasting insulin levels, HOMA-IR values, TPOAb levels, serum TSH levels, and serum uric acid levels in the PTC group were higher than those in the control group (p 0.05). After the multiple logistic regression analysis, the occurrence of PTC was positively associated with fasting insulin (odds ratio [OR] = 1.048, 95% confidence interval [CI]: 1.003-1.096, p = 0.037) and TPOAb levels (OR = 1.001, 95% CI: 1.000-1.002, p = 0.032). Moreover, TPOAb level was positively correlated with vague margin (r = 0.126, p = 0.045) and negatively correlated with homogeneous echo (r = -0.179, p = 0.004). However, fasting insulin levels were not correlated with pathological characteristics of PTC. Hyperinsulinemia and higher TPOAb levels might be the risk factors of PTC, but not disease severity in Chinese patients. PMID: 31118347 [PubMed - as supplied by ...

Millennials are often credited with driving the $4.2 trillion global wellness market, with their love of pursuits like yoga, meditation and boutique fitness. But despite their reputation for valuing health and wellness, millennials are in worse health than their elders in Generation X used to be, according to a new report from the Blue Cross Blue Shield Association. Millennials — who in 2017 were ages 21 to 36 — were overall in good health that year, according to Blue Cross’s data analysis of 55 million commercially insured millennials. But around age 27, millennials’ health began to decline —...

This study is a post-hoc analysis of steroid hormones before and after administration of pharmacological doses of soy isoflavones in a large cohort of men and women from two independent studies. Isoflavones are reported to inhibit mineralo- and glucocorticoid hormone production as well as reproductive steroids in vivo and in vitro. We focused on cytochrome P450 17α-hydroxylase (CYP17A1) which catalyses the production of dehydroepiandrosterone (DHEA), in the androgen biosynthesis pathway to elucidate effects on sex steroids in vitro. Design and Setting: Effects of soy isoflavones on steroid levels in two studies comp...

Abstract Background: Cancer survivors suffer from many comorbid conditions even after the cure of their cancers beyond 5 years. We explored the differences in the association of comorbid conditions between the cancer survivors and patients without cancer. Methods: Electronic medical records of 280 adult cancer survivors and 280 age-matched patients without cancer in our suburban internal medicine office were reviewed. Results: Mean age of the cancer survivors was 72.5 ± 13.1 years, and the age of the patients without cancer was 72.5 ± 12.8 years. The number of male cancer survivors was sign...

Abstract Background: The aim of this study was to investigate the relationship between vitamin D deficiency and thyroid diseases among type 2 diabetes mellitus (T2DM) patients. Methods: This was a cohort case and control study, 546 T2DM patients and 546 control study participants were enrolled, aged between 25 and 65 years. The subjects were also investigated for fasting blood glucose levels (FBG), post prandial glucose (PPG,) glycosylated hemoglobin (HbA1c), thyroid stimulating hormone (TSH), T3, T4, and presence of other comorbid conditions. Thyroid fine needle aspiration biopsy was suggested to patients wh...

By ANDY ORAM Clayton Christensen, the famous economist who popularized ideas of innovation and disruption, showed up at the recent Connected Health conference in Boston. Although billed as a panelist, he turned up without warning as a guest in a keynote and posed the same question I asked in an article back in July: “The overarching question: whither technology?” Like my article, Christensen distinguished between incremental improvements that don’t challenge current power structures or sources of revenue, and disruptive change that offers new solutions to old, intractable problems. Disruptive change, as s...

Headlines today announce that the new President of the American Heart Association (AHA), cardiologist Dr. John Warner, has suffered a heart attack, aborted by an emergency stent placement. Typical of the ridiculous attitudes that prevail at the industry-friendly AHA, they Tweeted: “Sending all our love and support to @American_Heart president Dr. Warner as he recovers from a mild heart attack. Heart disease can strike anyone, at any time. That’s why we keep fighting.” If you ignore the nonsense that AHA policy dictates, you can absolutely gain control over cardiovascular risk. But you will NOT find the an...

Credit For many women, turning 30 marks the real beginning of adulthood. You're established in a career, and maybe in a relationship. You might be thinking about starting a family. You feel pretty good about yourself, and all the health indiscretions of your 20s (remember those all-night parties and how you still managed to make it into work the next day?) haven't taken much of a health toll. But let's face it, ages 30 to 39 are prime time. All in all, the 30s are a very positive time for health, but it's also the time you have to start developing excellent habits as an investment in the future, says Dr. Debra DeJoseph,...

Abstract It is now recognized that FMR1 premutation carriers (PC) are at risk to develop a range of neurological, psychiatric, and immune-mediated disorders during adulthood. There are conflicting findings regarding the incidence of hypertension, hypothyroidism, diabetes, and cancer in these patients that warrant further study. A retrospective controlled study was performed in a convenience sample of 248 controls (130 men, 118 women) and 397 FMR1 PC with and without fragile X-associated tremor ataxia syndrome (FXTAS) (176 men, 221 women); all participants were at least 45 years old (men: mean 62.4, SD 9.5; wo...
