Stress is a powerful modulator of neuroendocrine, behavioral, and immunological functions. After 4.5-d repeated combined acoustic and restraint stress as a murine model of chronic psychological stress, severe metabolic dysregulations became detectable in female BALB/c mice. Stress-induced alterations of metabolic processes that were found in a hepatic mRNA expression profiling were verified by in vivo analyses. Repeatedly stressed mice developed a hypermetabolic syndrome with the severe loss of lean body mass, hyperglycemia, dyslipidemia, increased amino acid turnover, and acidosis. This was associated with hypercortisolism, hyperleptinemia, insulin resistance, and hypothyroidism. In contrast, after a single acute stress exposure, changes in expression of metabolic genes were much less pronounced and predominantly confined to gluconeogenesis, probably indicating that metabolic disturbances might be initiated already early but will only manifest in repeatedly stressed mice. Thus, in our murine model, repeated stress caused severe metabolic dysregulations, leading to a drastic reduction of the individual's energy reserves. Under such circumstances stress may further reduce the ability to cope with new stressors such as infection or cancer.

Noninsulindependent diabetes mellitus is 2-4 times more prevalent in Turner subjects as compared to normal females, and tends to develop at a younger age, but it is usually mild and responsive to weight loss or monotherapy. The primary pathogenic event is beta cell dysfunction, but insulin resistance also plays a central role and is worsened by the presence of hypertension, obesity and dyslipidemia which are common in Turner syndrome. We present the case of a 30 year-old female patient with short stature, 141cm (<-- 2.5 SD), overweight 51kg, waist circumference 79cm, triangular facies, downslanting palpebral fissures, low set ears, short neck, secondary amenorrhea, palpitations, a history of polyuria, polydypsia of three months duration and a fasting morning glucose of 260 mg/dL. Cardiac and renal defects were excluded, hormonologic evaluation was consistent with hypergonadotropic hypogonadism (FSH 65 mUI/mL) and primary hypothyroidism (TSH 5.68 microUI/mL) and karyotype was 45,XO. She also had hypercholesterolemia (247 mg/dL), hypocalcemia (8 mg/dL), mild elevation of hepatic enzymes (ALAT 51 U/L) and osteopenia (Tscore--2.22). Glycaemic control was achieved with diet only; therapy consisted of hormone replacement theraphy, thyroxine and beta blockers.

Systemic fungal infections are increasingly reported in immunocompromised patients with hematological malignancies, recipients of bone marrow and solid organ allografts, and patients with AIDS. Mycoses may infiltrate endocrine organs and adversely affect their function or produce metabolic complications, such as hypopituitarism, hyperthyroidism or hypothyroidism, pancreatitis, hypoadrenalism, hypogonadism, hypernatremia or hyponatremia, and hypercalcemia. Antifungal agents used for prophylaxis and/or treatment of mycoses also have adverse endocrine and metabolic effects, including hypoadrenalism, hypogonadism, hypoglycemia, dyslipidemia, hypernatremia, hypocalcemia, hyperphosphatemia, hyperkalemia or hypokalemia, and hypomagnesemia. Herein, we review how mycoses and conventional systemic antifungal treatment can affect the endocrine system and cause metabolic abnormalities. If clinicians are equipped with better knowledge of the endocrine and metabolic complications of fungal infections and antifungal therapy, they can more readily recognize them and favorably affect outcome.

Multiple studies suggest increased conversion of cholesterol to bile acids by cholesterol 7alpha-hydroxylase (CYP7A1) protects against dyslipidemia and atherosclerosis. CYP7A1 expression is repressed by the sequential activity of two nuclear hormone receptors, farnesoid X receptor (FXR) and small heterodimer partner (SHP). Here we demonstrate 129 strain SHP(-/-) mice are protected against hypercholesterolemia resulting from either a cholesterol/cholic acid (chol/CA) diet or from hypothyroidism. In a mixed 129-C57Bl/6 background, LDLR(-/-) and LDLR(-/-)SHP(-/-) mice had nearly identical elevations in hepatic cholesterol content and repression of cholesterol regulated genes when fed a Western diet. However, the LDLR(-/-)SHP(-/-) mice had greatly reduced elevations in serum VLDL and LDL cholesterol levels and triglyceride (TG) levels as compared with LDLR(-/-) mice. Additionally, the hepatic inflammation produced by the Western diet in the LDLR(-/-) mice was abolished in the LDLR(-/-)SHP(-/-) mice. CYP7A1 expression was induced 10-fold by the Western diet in the LDLR(-/-)SHP(-/-) mice but not in the LDLR(-/-) mice. Finally, hepatocyte-specific deletion of SHP expression was also protective against dyslipidemia induced by either a chol/CA diet or by hypothyroidism. While no antagonist ligands have yet been identified for SHP, these results suggest selective inhibition of hepatic SHP expression may provide protection against dyslipidemia.

Hitherto unknown efficacy of the peel extracts of Mangifera indica (MI), Cucumis melo (CM) and Citrullus vulgaris (CV) fruits in ameliorating the diet-induced alterations in dyslipidemia, thyroid dysfunction and diabetes mellitus have been investigated in rats. In one study, out of 4 different doses (50-300 mg/kg), 200 mg/kg of MI and 100 mg/kg for other two peel extracts could inhibit lipidperoxidation (LPO) maximally in liver. In the second experiment rats were maintained on pre-standardized atherogenic diet CCT (supplemented with 4% cholesterol, 1% cholic acid and 0.5% 2-thiouracil) to induce dyslipidemia, hypothyroidism and diabetes mellitus and the effects of the test peel extracts (200 mg/kg of MI and 100 mg/kg for CM and CV for 10 consecutive days) were studied by examining the changes in tissue LPO (in heart, liver and kidney), concentrations of serum lipids, thyroid hormones, insulin and glucose. Rats, treated simultaneously with either of the peel extracts reversed the CCT-diet induced increase in the levels of tissue LPO, serum lipids, glucose, creatinine kinase-MB and decrease in the levels of thyroid hormones and insulin indicating their potential to ameliorate the diet induced alterations in serum lipids, thyroid dysfunctions and hyperglycemia/diabetes mellitus. A phytochemical analysis indicated the presence of a high amount of polyphenols and ascorbic acid in the test peel extracts suggesting that the beneficial effects could be the result of the rich content of polyphenols and ascorbic acid in the studied peels.

We analyzed the late outcomes of 429 long-term survivors post allogeneic hematopoietic SCT (allo-HSCT) who received transplant in our center between 1981 and 2002, and were free of their primary disease for > or =2 years after allo-HSCT. Late recurrent primary malignancy was found in 58 (13.5%) patients and was the primary cause of late death. A total of 37 (8.6%) patients died of non-relapse causes at a median of 5.5 years (range, 2-15.6 years) post allo-HSCT. The major non-relapse causes of death were chronic GVHD (cGVHD), secondary malignancy and infection. The probabilities of OS and EFS were 85% (95% cumulative incidence (CI) (81-89%)) and 79% (95% CI (74-83%)) at 10 years, respectively. Long-term allo-HSCT survivors were evaluated for late complications (median follow-up, 8.6 years (range, 2.3-22.8 years)). cGVHD was diagnosed in 196 (53.1%) survivors. The endocrine and metabolic complications were hypogonadism in 134 (36.3%) patients, osteopenia/osteoporosis in 90 (24.4%), dyslipidemia in 33 (8.9%), hypothyroidism in 28 (7.6%) and diabetes in 28 (7.6%). Hypertension was diagnosed in 79 (21.4%), renal impairment in 70 (19.0%), depression in 40 (10.8%) and sexual dysfunction in 33 (8.9%) survivors. We conclude that in patients who receive allo-HSCT as treatment for hematological malignancy and who are free of their original disease 2 years post transplant, mortality is low and the probability of durable remission is high. Lifelong surveillance is recommended.

Peripheral arterial disease (PAD) is chronic arterial occlusive disease of the lower extremities caused by atherosclerosis whose prevalence increases with age. Only one-half of women with PAD are symptomatic. Symptomatic and asymptomatic women with PAD are at increased risk for all-cause mortality, cardiovascular mortality, and mortality from coronary artery disease. Modifiable risk factors that predispose women to PAD include active cigarette smoking, passive smoking, diabetes mellitus, hypertension, dyslipidemia, increased plasma homocysteine levels and hypothyroidism. With regard to management, women who smoke should be encouraged to quit and referred to a smoking cessation program. Hypertension, diabetes mellitus, dyslipidemia, and hypothyroidism require treatment. Statins reduce the incidence of intermittent claudication and improve exercise duration until the onset of intermittent claudication in women with PAD and hypercholesterolemia. Anti-platelet drugs such as aspirin or especially clopidogrel, angiotensin-converting enzyme inhibitors and statins should be given to all women with PAD. Beta blockers are recommended if coronary artery disease is present. Exercise rehabilitation programs and cilostazol increase exercise time until intermittent claudication develops. Chelation therapy should be avoided as it is ineffective. Indications for lower extremity percutaneous transluminal angioplasty or bypass surgery in women are (1) incapacitating claudication interfering with work or lifestyle; and (2) limb salvage in women with limb-threatening ischemia as manifested by rest pain, non-healing ulcers, and/or infection or gangrene. Future research includes investigation of mechanisms underlying why women have a higher risk of graft failure and major amputation.

To evaluate the prevalence of dyslipidemia in the population of Hashimoto thyroiditis, we reviewed medical records on the consecutive 1181 cases with adult Hashimoto thyroiditis and 830 cases were adopted for the study. First, the serum TSH level increased and serum free T4 level decreased, slightly but significantly, with increasing age. There were significant positive correlations between serum TSH levels and lipid parameters such as total cholesterol (TC), triglyceride (TG), HDL-cholesterol (HDL-C), LDL-cholesterol (LDL-C), non-HDL-C and LDL-C/HDL-C ratio (L/H). In contrast, there were significant negative correlations between serum free T4 levels and all of these lipid parameters. According to the thyroid function, the cases were classified into 4 groups such as thyrotoxicosis (TT), euthyroidism (EU), subclinical hypothyroidism (SH) and overt hypothyroidism (OH). TC, HDL-C, non-HDL-C and LDL-C of TT were significantly lower than those in EU. In contrast, TC, TG, non-HDL-C, LDL-C, L/H and age of OH were significantly higher than those in EU. Interestingly, LDL-C and L/H of SH were significantly higher compared with EU. Thirty-two of SH patients were treated with small doses of levothyroxine and the effects on the lipid profile were examined. The TC, non-HDL-C, LDL-C and L/H were significantly decreased after treatment. In conclusion, the prevalence of dyslipidemia increases along with hypofunction of the thyroid and T4 replacement therapy may improve lipid profile in the cases of SH with Hashimoto thyroiditis.

Subclinical hypothyroidism (SCH) is frequently encountered in the general population. Since it is generally asymptomatic, these patients are mostly identified through routine screening or evaluation of non-specific symptoms. It has been suggested as a risk factor for cardiovascular disease. On the other hand, mean platelet volume (MPV), which is a determinant of platelet function, is an independent risk factor for cardiovascular disease. The aim of this study was to evaluate MPV values in subclinical hypothyroidic patients when they were subclinical hypothyroidic and became euthyroidic after 12 weeks of levothyroxine replacement therapy. Sixty patients with subclinical hypothyroidism and 78 euthyroid healthy subjects matched for age, gender and body mass index were enrolled in the study. None of the study subject had diabetes, hypertension or dyslipidemia. All the study subjects were evaluated by biochemical and platelet parameters. Subclinical hypothyroidic patients were then reevaluated with the same parameters when they became euthyroid after 12 weeks of levothyroxine treatment. Platelet counts and metabolic parameters, except serum triglyceride and high density lipoprotein cholesterol (HDLC) levels, were similar between the two groups. Serum triglyceride and MPV values were significantly higher (pTG=0.007 and pMPV<0.001) while HDLC levels were lower (pHDLC=0.008) in the subclinical hypothyroidic group. MPV was found to be correlated with only antithyroid peroxidase (anti-TPO) antibody levels (P<0.001). MPV values were decreased after subclinical hypothyroidic patients became eythyroid. However, post-treatment MPV values were still higher (p=0.035) in the patient group than in control group. These results suggest that subjects with SCH are susceptible to increased platelet activation and increased MPV values which contribute to increased risk of cardiovascular complications.

Cancer recurrence is a very real concern for cancer survivors. Surveillance for recurrence and vigilance for development of new cancers are top priorities during follow-up visits after active treatment ends. However, the cancer survivor also is at risk for the development of comorbid conditions. These conditions, including obesity, diabetes, dyslipidemia, menopause, decreased bone mass, hypertension, and hypothyroidism, are discussed with their relevance for general health and their relationships to disease-specific cancers. All of these conditions should be routinely addressed as part of the patient's survivorship care when appropriate. The oncology nurse is in a prime position to educate survivors about the risks for these conditions, both through evidence-based practice guidelines specific to each condition and also through the use of a treatment summary and care plan. This article discusses these selected comorbidities and offers strategies for nurses to address them with survivors during follow-up visits. Clinical practice guidelines for comorbidities are included, along with oncology implications and relevance for survivors. Recommendations for modifiable risk factors and healthy living also are included, along with Web sites for survivorship care plans.
