    Full Text Available BACKGROUND: Obesity invokes a range of metabolic disturbances, but the transition from a poor to excessive nutritional environment may exacerbate adult metabolic dysfunction. The current study investigated global maternal nutrient restriction during early or late gestation on glucose tolerance and insulin sensitivity in the adult offspring when lean and obese. METHODS/PRINCIPAL FINDINGS: Pregnant sheep received adequate (1.0M; CE, n = 6 or energy restricted (0.7M diet during early (1-65 days; LEE, n = 6 or late (65-128 days; LEL, n = 7 gestation (term approximately 147 days. Subsequent offspring remained on pasture until 1.5 years when all received glucose and insulin tolerance tests (GTT & ITT and body composition determination by dual energy x-ray absorptiometry (DXA. All animals were then exposed to an obesogenic environment for 6-7 months and all protocols repeated. Prenatal dietary treatment had no effect on birth weight or on metabolic endpoints when animals were 'lean' (1.5 years. Obesity revealed generalised metabolic 'inflexibility' and insulin resistance; characterised by blunted excursions of plasma NEFA and increased insulin(AUC (from 133 to 341 [s.e.d. 26] ng.ml(-1.120 mins during a GTT, respectively. For LEL vs. CE, the peak in plasma insulin when obese was greater (7.8 vs. 4.7 [s.e.d. 1.1] ng.ml(-1 and was exacerbated by offspring sex (i.e. 9.8 vs. 4.4 [s.e.d. 1.16] ng.ml(-1; LEL male vs. CE male, respectively. Acquisition of obesity also significantly influenced the plasma lipid and protein profile to suggest, overall, greater net lipogenesis and reduced protein metabolism. CONCLUSIONS: This study indicates generalised metabolic dysfunction with adult-onset obesity which also exacerbates and 'reveals' programming of glucose-insulin sensitivity in male offspring prenatally exposed to maternal undernutrition during late gestation. Taken together, the data suggest that metabolic function appears little compromised in young

    The incidence of adult-onset T1D in low-risk non-HLA type has increased several folds, whereas the contemporaneous incidence in high-risk HLA-type remains stable. Various factors behind this selective increase in T1D in young adults remain unclear. Obesity and its associated abnormalities appear to be an important determinant; however, the underlying mechanism involved is not understood. Recently, we have developed two novel transgenic obese mice models, Mito-Ob and m-Mito-Ob, by expressing a pleiotropic protein prohibitin (PHB) and a phospho mutant form of PHB (Y114F-PHB or m-PHB) from the aP2 gene promoter, respectively. Both mice models develop obesity in a sex-neutral manner, independent of diet; but obesity associated chronic low-grade inflammation and insulin resistance in a male sex-specific manner. Interestingly, on a high fat diet (HFD) only male m-Mito-Ob mice displayed marked mononuclear cell infiltration in pancreas and developed insulitis that mimic adult-onset T1D. Male Mito-Ob mice that share the metabolic phenotype of male m-Mito-Ob mice, and female m-Mito-Ob that harbor m-PHB similar to male m-Mito-Ob mice, did not develop insulitis. Thus, insulitis development in male m-Mito-Ob in response to HFD requires both, obesity-related abnormalities and m-PHB. Collectively, this data provides a proof-of-concept that obesity-associated abnormalities couple environmental triggers with genetic susceptibility in adult-onset T1D and reveals PHB as a potential susceptibility gene for T1D.

  3. Ablation of NG2 proteoglycan leads to deficits in brown fat function and to adult onset obesity.

    Full Text Available Obesity is a major health problem worldwide. We are studying the causes and effects of obesity in C57Bl/6 mice following genetic ablation of NG2, a chondroitin sulfate proteoglycan widely expressed in progenitor cells and also in adipocytes. Although global NG2 ablation delays early postnatal adipogenesis in mouse skin, adult NG2 null mice are paradoxically heavier than wild-type mice, exhibiting larger white fat deposits. This adult onset obesity is not due to NG2-dependent effects on CNS function, since specific ablation of NG2 in oligodendrocyte progenitors yields the opposite phenotype; i.e. abnormally lean mice. Metabolic analysis reveals that, while activity and food intake are unchanged in global NG2 null mice, O(2 consumption and CO(2 production are decreased, suggesting a decrease in energy expenditure. Since brown fat plays important roles in regulating energy expenditure, we have investigated brown fat function via cold challenge and high fat diet feeding, both of which induce the adaptive thermogenesis that normally occurs in brown fat. In both tests, body temperatures in NG2 null mice are reduced compared to wild-type mice, indicating a deficit in brown fat function in the absence of NG2. In addition, adipogenesis in NG2 null brown pre-adipocytes is dramatically impaired compared to wild-type counterparts. Moreover, mRNA levels for PR domain containing 16 (PRDM16 and peroxisome proliferator-activated receptor γ coactivator (PGC1-α, proteins important for brown adipocyte differentiation, are decreased in NG2 null brown fat deposits in vivo and NG2 null brown pre-adipocytes in vitro. Altogether, these results indicate that brown fat dysfunction in NG2 null mice results from deficits in the recruitment and/or development of brown pre-adipocytes. As a consequence, obesity in NG2 null mice may occur due to disruptions in brown fat-dependent energy homeostasis, with resulting effects on lipid storage in white adipocytes.

    Asthma is a heterogeneous disease with many phenotypes, and age at disease onset is an important factor in separating the phenotypes. Genetic factors, atopy, and early respiratory tract infections are well-recognized factors predisposing to childhood-onset asthma. Adult-onset asthma is more often associated with obesity, smoking, depression, or other life-style or environmental factors, even though genetic factors and respiratory tract infections may also play a role in adult-onset disease.

    2014-03-01

    Full Text Available Patients with adult onset non-familial progressive ataxia are classified in sporadic ataxia group. There are several disease categories that may manifest with sporadic ataxia: toxic causes, immune-mediated ataxias, vitamin deficiency, infectious diseases, degenerative disorders and even genetic conditions. Considering heterogeneity in the clinical spectrum of sporadic ataxias, the correct diagnosis remains a clinical challenge. In this review, the different disease categories that lead to sporadic ataxia with adult onset are discussed with special emphasis on their clinical and neuroimaging features, and diagnostic criteria.

    Full Text Available Disabling pansclerotic morphea (DPM is a rare, severe, and mutilating form of morphea, involving the dermis, subcutaneous tissue, fat, muscle, and even bone. It is usually seen before the age of 14 years, with the patient complaining of arthralgia and stiffness at the time of onset. We report a case of unilateral adult-onset DPM with sparing of the face. Within a few months of onset, painful contracture deformities of the hand, elbow, and shoulder joints developed, impairing the patient′s normal daily activities. We are reporting this case because of the unusual presentation: DPM in an adult, with history of trauma in childhood and rapid onset of complications, is rare.

  9. Respiratory infections precede adult-onset asthma.

    Directory of Open Access Journals (Sweden)

    Aino Rantala

    Full Text Available BACKGROUND: Respiratory infections in early life are associated with an increased risk of developing asthma but there is little evidence on the role of infections for onset of asthma in adults. The objective of this study was to assess the relation of the occurrence of respiratory infections in the past 12 months to adult-onset asthma in a population-based incident case-control study of adults 21-63 years of age. METHODS/PRINCIPAL FINDINGS: We recruited all new clinically diagnosed cases of asthma (n = 521 during a 2.5-year study period and randomly selected controls (n = 932 in a geographically defined area in South Finland. Information on respiratory infections was collected by a self-administered questionnaire. The diagnosis of asthma was based on symptoms and reversible airflow obstruction in lung function measurements. The risk of asthma onset was strongly increased in subjects who had experienced in the preceding 12 months lower respiratory tract infections (including acute bronchitis and pneumonia with an adjusted odds ratio (OR 7.18 (95% confidence interval [CI] 5.16-9.99, or upper respiratory tract infections (including common cold, sinusitis, tonsillitis, and otitis media with an adjusted OR 2.26 (95% CI 1.72-2.97. Individuals with personal atopy and/or parental atopy were more susceptible to the effects of respiratory infections on asthma onset than non-atopic persons. CONCLUSIONS/SIGNIFICANCE: This study provides new evidence that recently experienced respiratory infections are a strong determinant for adult-onset asthma. Reducing such infections might prevent onset of asthma in adulthood, especially in individuals with atopy or hereditary propensity to it.

  10. An unusual cause of adult onset cerebellar ataxia with hypogonadism

    2009-01-01

    Full Text Available We report an unusual case of sporadic adult onset cerebellar ataxia with hypogonadism. A 40-year-old unmarried man presented with progressive ataxia and dysarthria along with complaints of non-development of secondary sexual characteristics and erectile dysfunction. There were complaints of intermittent diarrhea. Clinical examination revealed a pan-cerebellar syndrome with features of hypoandrogenism. No eye movement abnormalities were evident. There were signs of malabsorption. Investigations confirmed the presence of auto-antibodies found in celiac disease, and a duodenal biopsy confirmed the same. Hypoandrogenism was postulated to be due to hypergonadotropic hypogonadism which has been mentioned in a few patients of celiac disease. However, the pattern seen in our patient was of a hypogonadotropic hypogonadism. This is probably secondary to an autoimmune hypophysitis seen in some patients in the absence of other clinical manifestations. Autoantibody testing should be a diagnostic necessity in any adult with a sporadic cerebellar ataxia.

    Nemaline myopathy is a rare congenital myopathy that generally presents in childhood. We report a case of a 44-year-old man who presented with severe hypoxic hypercapnic respiratory failure as the initial manifestation of nemaline myopathy. After starting noninvasive ventilation, his pulmonary function test results improved substantially, and over the 4 years since diagnosis his respiratory function remained stable. There are few reported cases of respiratory failure in patients with adult-onset nemaline myopathy, and the insidious onset in this case is even more unusual. This case highlights the varied presenting features of adult-onset nemaline myopathy and that noninvasive ventilation improves respiratory function.

    Acne vulgaris is usually considered as a skin disorder that primarily affects adolescents reaching a peak at the age of 14-17 years in females and 16-19 years in males. However, recent epidemiologic studies have shown that a significant number of female patients aged >25 years experience acne. As it is regarded as a disease of teenagers, adults are more apprehensive and experience social anxiety. Hence, adult onset acne has become a matter of concern. PMID:27512185

  16. Season of Birth and Risk for Adult Onset Glioma

    2010-04-01

    Full Text Available Adult onset glioma is a rare cancer which occurs more frequently in Caucasians than African Americans, and in men than women. The etiology of this disease is largely unknown. Exposure to ionizing radiation is the only well established environmental risk factor, and this factor explains only a small percentage of cases. Several recent studies have reported an association between season of birth and glioma risk. This paper reviews the plausibility of evidence focusing on the seasonal interrelation of farming, allergies, viruses, vitamin D, diet, birth weight, and handedness. To date, a convincing explanation for the occurrence of adult gliomas decades after a seasonal exposure at birth remains elusive.

  17. Usual interstitial pneumonia in adult-onset still's disease

    International Nuclear Information System (INIS)

    Adult-onset still's disease (AOSD) is a multi-system inflammatory disorder of unknown origin, characterized by high spiking fevers, evanescent salmon colored rash, arthralgias or arthritis, hepatospleno-megaly, Iymphadenopathy and sore throat. It is not uncommon for AOSD to involve other organs, such as the liver, the kidney; the bone marrow and less often the lungs. Pulmonary involvement ranges from 30 to 40 % (0 to 53 %), the pulmonary manifestations of AOSD include pleurisy, acute pneumonitis and even the acute respiratory distress syndrome. We present a case of a patient with AOSD who developed an interstitial lung disease and reviewed the literature on it

  18. Clinical and MRI features of supratentorial gliomas with adult-onset epilepsy

    International Nuclear Information System (INIS)

    Although some patients with supratentorial gliomas develop epilepsy in their clinical course, the details of adult-onset epilepsy with gliomas have not been fully evaluated. This paper reports on 15 cases of supratentorial glioma with the sole symptom of adult-onset epilepsy and characterizes their clinical and MRI features. The patients, 5 males and 10 females, developed the first epilepsy at the mean age of 37 years. Generalized seizure was encountered in all cases and focal seizure alone was never seen. Seizure was satisfactorily controlled with anticonvulsants in all except 2 cases. The tumor was located in the frontal lobe (9 cases) or temporal lobe (6 cases). Histologically, there were 12 astrocytomas, 2 glioblastomas, and 1 oligoastrocytoma. Of these, 12 were benign gliomas. Surprisingly, CT scan and MRI revealed tumors larger than predicted. The abnormal intensity region was delineated most prominently on T2-weighted SE image and was broader on T2-weighted spin echo image than on T1-weighted spin echo and inversion recovery image. The authors conclude that gliomas presenting with epilepsy tend to be histologically benign, are predominantly seen in middle-aged women, and are located in the frontal and temporal lobes. Although a tumor may be large enough to be detected on CT scan or MRI, as in the present study, histological examination is needed to establish the diagnosis. Additionally, gliomas with equivocal abnormalities on CT and MRI do evolve despite further neurological deficits, so meticulous evaluation including stereotactic biopsy is the method of choice. Finally, T2-weighted SE image in the coronal plane is advocated for patients with adult-onset epilepsy to achieve accurate diagnosis and to initiate early treatment. (author)

    Full Text Available Adult Still's Disease was first described in 1971 by Bywaters in fourteen adult female patients who presented with symptoms indistinguishable from that of classic childhood Still's Disease (Bywaters, 1971. George Still in 1896 first recognized this triad of quotidian (daily fevers, evanescent rash, and arthritis in children with what later became known as juvenile inflammatory arthritis (Still, 1990. Adult Onset Still's Disease (AOSD is an inflammatory condition of unknown etiology characterized by an evanescent rash, quotidian fevers, and arthralgias. Numerous infectious agents have been associated with its presentation. This case is to our knowledge the first presentation of AOSD in the setting of Rocky Mountain Spotted Fever. Although numerous infectious agents have been suggested, the etiology of this disorder remains elusive. Nevertheless, infection may in fact play a role in triggering the onset of symptoms in those with this disorder.

    Full Text Available Mariam Siddiqui,1 Michael S Putman,2 Anisha B Dua,11Department of Rheumatology, 2Department of Internal Medicine, The University of Chicago Medical Center, Chicago, IL, USA Abstract: Adult-onset Still's disease (AOSD – a multi-systemic inflammatory condition characterized by high fevers, polyarthritis, an evanescent rash, and pharyngitis – has been a challenging condition to diagnose expediently and treat effectively. Questions remain regarding the underlying pathophysiology and etiology of AOSD. Pathognomonic diagnostic tests and reliable biomarkers remain undiscovered. Over the past decade, important progress has been made. Diagnostic criteria employing glycosylated ferritin have improved specificity. More important, novel biologic therapies have offered important clues to AOSD's underlying pathophysiology. Cytokine-specific biologic therapies have been instrumental in providing more effective treatment for disease refractory to conventional treatment. While IL-1 therapy has demonstrated efficacy in refractory disease, novel therapies targeting IL-6 and IL-18 show great promise and are currently under investigation.

    Glycogen storage disease type II (GSDII), also referred to as Pompe disease or acid maltase deficiency, is a rare inherited condition caused by a deficiency in acid alpha-glucosidase (GAA) enzyme activity. The condition is often classified by age of presentation, with infantile and late onset variants (Laforet et al. J Neurology 55:1122-8, 2000). Late onset tends to present with progressive proximal muscle weakness and respiratory insufficiency (Winkel et al. J Neurology 252:875-84, 2005). We report two cases of biopsy confirmed adult onset GSDII, along with key Magnetic Resonance (MR) images. (orig.)

    2006-02-01

    Whereas hyperthyroidism is the most common endocrine disorder in the cat, hypothyroidism is the least common feline endocrine disorder. This is a the result of several factors including low index of suspicion, rarity of the naturally occurring hypothyroidism in cats, and a lack of species specific tests for endogenous TSH and antithyroglobulin antibodies. Nonetheless, hypothyroidism does occur in cats, especially in kittens and after radioactive treatment for hyperthyroidism. The clinician should become familiar with the common presentations of congenital and adult-onset hypothyroidism in cats. In addition, some of the tests specific to dogs (such as endogenous canine TSH) may be utilized to diagnose subclinical hypothyroidism in cats. Fortunately, the treatment of feline hypothyroidism with synthetic levothyroxine is both straightforward and effective. PMID:16584030

    Full Text Available Twenty-four cases of sporadic olivo-ponto-cerebellar atrophy (OPCA of adult onset were studied over a period of two years. Results suggest that this disorder has its usual onset in the 5th and 6th decade of life with a male: female ratio of 2:1. It manifests clinically with gait ataxia in all, dysarthria, other cerebellar signs and autonomic involvement in vast majority. There were features of basal ganglia involvement in some. No known identifiable environmental cause was found and genetically they are quite distinct from the known autosomal dominant spinocerebellar ataxias though sporadic occurrence in recessive inheritance or a de novo mutation could not be ruled out completely, but it is unlikely.

    Erythropoietin regulates erythropoiesis in a hypoxia-inducible manner. Here we generate inherited super-anaemic mice (ISAM) as a mouse model of adult-onset anaemia caused by erythropoietin deficiency. ISAM express erythropoietin in the liver but lack erythropoietin production in the kidney. Around weaning age, when the major erythropoietin-producing organ switches from the liver to the kidney, ISAM develop anaemia due to erythropoietin deficiency, which is curable by administration of recombinant erythropoietin. In ISAM severe chronic anaemia enhances transgenic green fluorescent protein and Cre expression driven by the complete erythropoietin-gene regulatory regions, which facilitates efficient labelling of renal erythropoietin-producing cells. We show that the majority of cortical and outer medullary fibroblasts have the innate potential to produce erythropoietin, and also reveal a new set of erythropoietin target genes. ISAM are a useful tool for the evaluation of erythropoiesis-stimulating agents and to trace the dynamics of erythropoietin-producing cells. PMID:23727690

    2012-02-01

    Adult-onset primary torsion dystonia (AOPTD) has an autosomal dominant pattern of inheritance with markedly reduced penetrance; the genetic causes of most forms of AOPTD remain unknown. Endophenotypes, markers of sub-clinical gene carriage, may be of use detecting non-manifesting gene carriers in relatives of AOPTD patients. The aim of this study was to compare the utility of the spatial discrimination threshold (SDT) and temporal discrimination threshold (TDT) as potential endophenotypes in AOPTD. Data on other published candidate endophenotypes are also considered. Both SDT and TDT testing were performed in 24 AOPTD patients and 34 of their unaffected first degree relatives; results were compared with normal values from a control population. Of the 24 AOPTD patients 5 (21%) had abnormal SDTs and 20 (83%) had abnormal TDTs. Of the 34 first degree relatives 17 (50%) had abnormal SDTs and 14 (41%) had abnormal TDTs. Discordant results on SDT and TDT testing were found in 16 (67%) AOPTD patients and 21 (62%) first degree relatives. TDT testing has superior sensitivity compared to SDT testing in AOPTD patients; although false positive TDTs are recognised, the specificity of TDT testing in unaffected relatives is not determinable. The high level of discordance between the two tests probably relates methodological difficulties with SDT testing. The SDT is an unreliable AOPTD endophenotype; TDT testing fulfils criteria for a reliable endophenotype with a high sensitivity.

    Full Text Available Interleukin 1β (IL-1β is emerging as a master mediator of adult onset Still’s disease (AOSD pathogenesis. This pleiotropic cytokine, whose expression is under the control of the inflammasome pathway, has a wide type of effects. As a key mediator of innate immunity is a potent pyrogen and facilitates neutrophilic proliferation and diapedesis into the inflamed tissues, which are key AOSD manifestations. The study of proinflammatory cytokines profiles in sera and pathological tissues of AOSD patients has shown elevated levels of IL-1β, these levels being highly correlated with disease activity and severity. These experimental evidences and the analogy with other autoinflammatory diseases that share with AOSD clinical and biological characteristics have suggested the blockade of IL-1β as a possible new therapeutic option for the AOSD, especially in conventional therapy resistant cases. Anakinra, the first anti-IL-1 agent put on the market, has demonstrated capable to induce a rapid response sustained over time, especially in systemic forms, where anti-TNFα failed to control symptoms. While a growing number of evidences supports the utilisation of anakinra in AOSD, a new generation of anti-IL1β antagonists is developing. Canakinumab and rilonacept, thanks to their higher affinity and longer half-life, could improve the management of this invalidating disease.

This review presents a comprehensive synopsis of their epidemiology, pathophysiology, and clinical presentations; describes how they can be distinguished; and considers both established and proposed new approaches to their management. Both adult-onset asthma and COPD are complex diseases arising from gene–environment interactions. Early life exposures such as childhood infections, smoke, obesity, and allergy influence adult-onset asthma. While the established environmental risk factors for COPD are adult tobacco and biomass smoke, there is emerging evidence that some childhood exposures such as maternal smoking and infections may cause COPD. Asthma has been characterized predominantly by Type 2 helper T cell (Th2 cytokine-mediated eosinophilic airway inflammation associated with airway hyperresponsiveness. In established COPD, the inflammatory cell infiltrate in small airways comprises predominantly neutrophils and cytotoxic T cells (CD8 positive lymphocytes. Parenchymal destruction (emphysema in COPD is associated with loss of lung tissue elasticity, and small airways collapse during exhalation. The precise definition of chronic airflow limitation is affected by age; a fixed cut-off of forced expiratory volume in 1 second/forced vital capacity leads to overdiagnosis of COPD in the elderly. Traditional approaches to distinguishing between asthma and COPD have highlighted age of onset

    Neuronal intranuclear inclusion disease (NIID) is an uncommon progressive neurodegenerative disorder. Adult-onset NIID can result in prominent dementia. We herein describe the case of a 74-year-old man who presented with dementia, cerebellar ataxia, neuropathy, and autonomic dysfunction. Diffusion-weighted imaging showed hyperintensity of the corticomedullary junction. Fluid-attenuated inversion recovery images showed frontal-dominant white matter hyperintensity. NIID was diagnosed from the presence of intranuclear inclusions in a skin biopsy sample. Neuropsychological testing revealed memory loss and frontal cognitive dysfunction, especially in relation to language and executive functions. We were therefore able to confirm the association of NIID with cognitive dysfunction. PMID:27523009

  13. Sporadic adult onset primary torsion dystonia is a genetic disorder by the temporal discrimination test.

    2012-02-01

    Adult-onset primary torsion dystonia is an autosomal dominant disorder with markedly reduced penetrance; patients with sporadic adult-onset primary torsion dystonia are much more prevalent than familial. The temporal discrimination threshold is the shortest time interval at which two stimuli are detected to be asynchronous and has been shown to be abnormal in adult-onset primary torsion dystonia. The aim was to determine the frequency of abnormal temporal discrimination thresholds in patients with sporadic adult-onset primary torsion dystonia and their first-degree relatives. We hypothesized that abnormal temporal discrimination thresholds in first relatives would be compatible with an autosomal dominant endophenotype. Temporal discrimination thresholds were examined in 61 control subjects (39 subjects <50 years of age; 22 subjects >50 years of age), 32 patients with sporadic adult-onset primary torsion dystonia (cervical dystonia n = 30, spasmodic dysphonia n = 1 and Meige\\'s syndrome n = 1) and 73 unaffected first-degree relatives (36 siblings, 36 offspring and one parent) using visual and tactile stimuli. Z-scores were calculated for all subjects; a Z > 2.5 was considered abnormal. Abnormal temporal discrimination thresholds were found in 1\\/61 (2%) control subjects, 27\\/32 (84%) patients with adult-onset primary torsion dystonia and 32\\/73 (44%) unaffected relatives [siblings (20\\/36; 56%), offspring (11\\/36; 31%) and one parent]. When two or more relatives were tested in any one family, 22 of 24 families had at least one first-degree relative with an abnormal temporal discrimination threshold. The frequency of abnormal temporal discrimination thresholds in first-degree relatives of patients with sporadic adult-onset primary torsion dystonia is compatible with an autosomal dominant disorder and supports the hypothesis that apparently sporadic adult-onset primary torsion dystonia is genetic in origin.

    SLC25A13 (citrin or aspartate-glutamate carrier 2) is located in the mitochondrial membrane in the liver and its genetic deficiency causes adult-onset type II citrullinemia (CTLN2). CTLN2 is one of the urea cycle disorders characterized by sudden-onset hyperammonemia due to reduced argininosuccinate synthase activity. This disorder is frequently accompanied with hepatosteatosis in the absence of obesity and ethanol consumption. However, the precise mechanism of steatogenesis remains unclear. The expression of genes associated with fatty acid (FA) and triglyceride (TG) metabolism was examined using liver samples obtained from 16 CTLN2 patients and compared with 7 healthy individuals. Although expression of hepatic genes associated with lipogenesis and TG hydrolysis was not changed, the mRNAs encoding enzymes/proteins involved in FA oxidation (carnitine palmitoyl-CoA transferase 1α, medium- and very-long-chain acyl-CoA dehydrogenases, and acyl-CoA oxidase 1), very-low-density lipoprotein secretion (microsomal TG transfer protein), and FA transport (CD36 and FA-binding protein 1), were markedly suppressed in CTLN2 patients. Serum concentrations of ketone bodies were also decreased in these patients, suggesting reduced mitochondrial β-oxidation activity. Consistent with these findings, the expression of peroxisome proliferator-activated receptor α (PPARα), a master regulator of hepatic lipid metabolism, was significantly down-regulated. Hepatic PPARα expression was inversely correlated with severity of steatosis and circulating ammonia and citrulline levels. Additionally, phosphorylation of c-Jun-N-terminal kinase was enhanced in CTLN2 livers, which was likely associated with lower hepatic PPARα. Collectively, down-regulation of PPARα is associated with steatogenesis in CTLN2 patients. These findings provide a novel link between urea cycle disorder, lipid metabolism, and PPARα. PMID:25533124

    A 43-year-old male presented with abnormal behavior and consciousness disturbance on the day after traveling abroad and was admitted to our hospital. Laboratory tests showed hyperammonemia and hypercitrullinemia. The electro-encephalogram showed frontal dominant bilateral slow δ burst. He had a peculiar taste for nuts. But he didn't take nuts during the overseas travel for 3 days. The family history revealed that his younger brother died of a status epilepticus of unknown cause at the age of 29. These findings were compatible with hepatic encephalopathy due to adult-onset type II citrullinemia (CTLN2). Gene analysis provided a definite diagnosis of CTLN2. Diet and drug therapy have improved his condition. He is due to have liver transplantation which is the only established radical treatment for CTLN2 if his condition becomes worse. The present case shows that cessation of the habitual intake of nuts only for 3 days could lead to onset of CTLN2. PMID:25283831

    We describe a case of untreated adult-onset Coats' disease with a proliferative epiretinal membrane (ERM) treated successfully with 25-gauge pars plana vitrectomy (25GPPV). A 26-year-old man presented with a 3-week history of decreased vision in his left eye. At the initial examination, the decimal best-corrected visual acuity (BCVA) was 0.7 in the left eye. Ophthalmoscopy revealed the typical appearance of Stage 2A Coats' disease but with a proliferative ERM in the posterior pole. The patient received 2 monthly intravitreal injections of 2.5 mg bevacizumab, 5 laser photocoagulations to the area of telangiectasia, and 1 session of cryoretinopexy. Nine months after the initial visit, a traction by the ERM on the parafoveal area developed causing macular edema which reduced the BCVA to 0.3. He underwent 25GPPV with the removal of the ERM. In addition, the peripheral telangiectasia was treated intraoperatively with both laser photocoagulation and cryoretinopexy. Postoperatively, the traction to the parafoveal area was released and the BCVA improved to 0.6 which remained stable during the follow-up period of 13 months. We conclude that 25GPPV combined with ERM peeling, laser photocoagulation, and cryoretinopexy can be effective for adult-onset Coats' disease associated with an ERM. PMID:25817290

    Adult-onset Still's disease is a rare disorder with potentially severe clinical features, including cardiac involvement. This systemic inflammatory disease of unknown origin should be considered in the differential diagnosis of pericarditis, with or without pericardial effusion. Cardiac tamponade is a very rare sequela that requires an invasive approach, such as percutaneous or surgical pericardial drainage, in addition to the usual conservative therapy. The authors describe a case of adult-onset Still's disease rendered more difficult by pericarditis and cardiac tamponade, and they briefly review the literature on this entity. PMID:26175648

    Full Text Available Abstract Background Alexander disease (ALX is a rare neurological disorder characterized by white matter degeneration and cytoplasmic inclusions in astrocytes called Rosenthal fibers, labeled by antibodies against glial fibrillary acidic protein (GFAP. Three subtypes are distinguished according to age at onset: infantile (under age 2, juvenile (age 2 to 12 and adult (over age 12. Following the identification of heterozygous mutations in GFAP that cause this disease, cases of adult-onset ALX have been increasingly reported. Case Presentation We present a 60-year-old Japanese man with an unremarkable past and no family history of ALX. After head trauma in a traffic accident at the age of 46, his character changed, and dementia and dysarthria developed, but he remained independent. Spastic paresis and dysphagia were observed at age 57 and 59, respectively, and worsened progressively. Neurological examination at the age of 60 revealed dementia, pseudobulbar palsy, left-side predominant spastic tetraparesis, axial rigidity, bradykinesia and gaze-evoked nystagmus. Brain MRI showed tadpole-like atrophy of the brainstem, caused by marked atrophy of the medulla oblongata, cervical spinal cord and midbrain tegmentum, with an intact pontine base. Analysis of the GFAP gene revealed a heterozygous missense mutation, c.827G>T, p.R276L, which was already shown to be pathogenic in a case of pathologically proven hereditary adult-onset ALX. Conclusion The typical tadpole-like appearance of the brainstem is strongly suggestive of adult-onset ALX, and should lead to a genetic investigation of the GFAP gene. The unusual feature of this patient is the symmetrical involvement of the basal ganglia, which is rarely observed in the adult form of the disease. More patients must be examined to confirm, clinically and neuroradiologically, extrapyramidal involvement of the basal ganglia in adult-onset ALX.

    Hartnup disease is an inborn abnormality of renal and intestinal transport involving the neutral amino acids. Intermittent pellagra-like rash, attacks of cerebellar ataxia and psychiatric disturbance are characteristic symptoms of this disease. We described here a patient with adult-onset Hartnup disease who presented unique neuropsychiatric symptoms but no dermatologic symptoms, and reported features of amino acids transport in this patient and his family. The patient, a man aged 37 years, was referred to us because of lasting daytime bruxism. He is the second child of healthy parents who are first cousin; his elder brother who has been mentally retarded became bed-ridden and died at 32 years of age. His younger brother is completely healthy. Although the patient's development in infancy has been slightly retarded, he completed compulsory 9-year education. At 29 years of age, he experienced episodes of diplopia, ataxic gait and insomnia, and at 33 years of age, of transient stupor. There had been no history of photosensitivity or dermatitis. On neurological examination, there were trunkal ataxia, increased muscular tone and decreased mental activity besides bruxism. These symptoms remained unchanged despite of several medications including trihexyphenidyl, diazepam, halloperidol, tiapride and sulpiride. Two months later, the patient became stuporous; bruxism and hypertonicity became exaggerated. Myerson's sign, sucking reflex and grasp reflex in both hand appeared. There was no dermal lesion. A cranial computed tomography revealed a small calcification in the right frontal subcortical region and a single photon emission tomography indicated possible bifrontal hypoperfusion. Electroencephalograms demonstrated non-specific slowing. Somatosensory evoked potentials and nerve conduction velocities were normal. There were constant indicanuria and amino-aciduria.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2582682

  4. Temporal discrimination threshold: VBM evidence for an endophenotype in adult onset primary torsion dystonia.

    Familial adult-onset primary torsion dystonia is an autosomal dominant disorder with markedly reduced penetrance. Most adult-onset primary torsion dystonia patients are sporadic cases. Disordered sensory processing is found in adult-onset primary torsion dystonia patients; if also present in their unaffected relatives this abnormality may indicate non-manifesting gene carriage. Temporal discrimination thresholds (TDTs) are abnormal in adult-onset primary torsion dystonia, but their utility as a possible endophenotype has not been examined. We examined 35 adult-onset primary torsion dystonia patients (17 familial, 18 sporadic), 42 unaffected first-degree relatives of both familial and sporadic adult-onset primary torsion dystonia patients, 32 unaffected second-degree relatives of familial adult-onset primary torsion dystonia (AOPTD) patients and 43 control subjects. TDT was measured using visual and tactile stimuli. In 33 unaffected relatives, voxel-based morphometry was used to compare putaminal volumes between relatives with abnormal and normal TDTs. The mean TDT in 26 control subjects under 50 years of age was 22.85 ms (SD 8.00; 95% CI: 19.62-26.09 ms). The mean TDT in 17 control subjects over 50 years was 30.87 ms (SD 5.48; 95% CI: 28.05-33.69 ms). The upper limit of normal, defined as control mean + 2.5 SD, was 42.86 ms in the under 50 years group and 44.58 ms in the over 50 years group. Thirty out of thirty-five (86%) AOPTD patients had abnormal TDTs with similar frequencies of abnormalities in sporadic and familial patients. Twenty-two out of forty-two (52%) unaffected first-degree relatives had abnormal TDTs with similar frequencies in relatives of sporadic and familial AOPTD patients. Abnormal TDTs were found in 16\\/32 (50%) of second-degree relatives. Voxel-based morphometry analysis comparing 13 unaffected relatives with abnormal TDTs and 20 with normal TDTs demonstrated a bilateral increase in putaminal grey matter in unaffected relatives with abnormal

    2012-10-01

    Full Text Available Abstract Introduction Lymphadenopathy is found in about 65% of patients with adult-onset Still’s disease and is histologically characterized by an intense, paracortical immunoblastic hyperplasia. Adult-onset Still’s disease has not been previously described as an etiology of suppurative necrotizing granulomatous lymphadenitis. Case presentation We describe a 27-year-old Greek man who manifested prolonged fever, abdominal pain, increased inflammatory markers, episodic skin rash and mesenteric lymphadenopathy histologically characterized by necrotizing granulomatous adenitis with central suppuration. Disease flares were characterized by systemic inflammatory response syndrome with immediate clinico-laboratory response to corticosteroids but the patient required prolonged administration of methylprednisolone at a dose of above 12mg/day for disease control. After an extensive diagnostic work-up, which ruled out any infectious, malignant, rheumatic or autoinflammatory disease the patient was diagnosed as having adult-onset Still’s disease. The patient is currently treated with 4mg of methylprednisolone, 100mg of anakinra daily and methotrexate 7.5mg for two consecutive days per week and exerts full disease remission for six months. Conclusion To the best of our knowledge this is the first report of suppurative necrotizing granulomatous lymphadenitis attributed to adult-onset Still’s disease. This case indicates that the finding of a suppurative necrotizing granulomatous lymphadenitis should not deter the consideration of adult-onset Still’s disease as a potential diagnosis in a compatible clinical context; however, the exclusion of other diagnoses is a prerequisite.

    Full Text Available Leukoencephalopathy with brain stem and spinal cord involvement and high lactate (LBSL is a recently described leukoencephalopathy with a genetically proven underlying defect. Clinical features are slowly progressive pyramidal, cerebellar and dorsal column dysfunction with childhood or rarely adult onset. The genetic basis of the disease was recently identified, which concerned mutations in the DARS2 gene encoding mitochondrial aspartly-tRNA synthetase. The disease has distinct magnetic resonance imaging findings including inhomogeneous cerebral white matter abnormalities and selective brain stem and spinal cord tract involvement. Additionally, there are usually increased lactate levels on magnetic resonance spectroscopy (MRS of the abnormal white matter. In this case report, we describe the clinical and radiological features of a patient with genetically proven adult-onset LBSL and normal lactate levels on MRS.

  7. Clinical value of serum ferritin level in the adult onset still disease

    International Nuclear Information System (INIS)

    Objective: To investigate the clinical value of serum ferritin level in the adult onset still disease. Methods: Twenty patients enrolled were all met Yamaguchi criteria for claasification of adult's Still disease,their clinical features and treatment were reviewed, and the levels of serum ferritin, blood sedimentation, C reactive protein were detected. Furthermore, the correlativity between serum ferritin and ESR, CRP was analysed. Results: Comparing with those of previous treatment, the levels of SF, ESR, CRP of post-treatment were notably lower (P<0.001). There is negative correlativity between serum ferritin and ESR, CRP (P<0.05). Conclusion: The serum ferritin will probably indicate the activity of disease. The detection of serum ferritin will be helpful to the treatment of adult onset Still disease. (authors)

    OBJECTIVE Adult-onset hydrocephalus is not commonly discussed in the literature, especially regarding its demographic distribution. In contrast to pediatric hydrocephalus, which is related to a primary CSF pathway defect, its development in adults is often secondary to other pathologies. In this study, the authors investigated the epidemiology of adult-onset hydrocephalus as it pertains to different etiologies and in reference to age, sex, and race distributions. METHODS The authors retrospectively reviewed the clinical notes of 2001 patients with adult-onset hydrocephalus who presented to Louisiana State University Health Sciences Center within a 25-year span. Significant differences between the groups were analyzed by a chi-square test; p < 0.05 was considered significant. RESULTS The overall mean (± SEM) incidence of adult hydrocephalus in this population was 77 ± 30 per year, with a significant increase in incidence in the past decade (55 ± 3 [1990-2003] vs 102 ± 6 [2004-2015]; p < 0.0001). Hydrocephalus in a majority of the patients had a vascular etiology (45.5%) or was a result of a tumor (30.2%). The incidence of hydrocephalus in different age groups varied according to various pathologies. The incidence was significantly higher in males with normal-pressure hydrocephalus (p = 0.03) or head injury (p = 0.01) and higher in females with pseudotumor cerebri (p < 0.0001). In addition, the overall incidence of hydrocephalus was significantly higher in Caucasian patients (p = 0.0002) than in those of any other race. CONCLUSIONS Knowledge of the demographic variations in adult-onset hydrocephalus is helpful in achieving better risk stratification and better managing the disease in patients. For general applicability, these results should be validated in a large-scale meta-analysis based on a national population database. PMID:27581317

    Niemann-Pick disease type C (NP-C) is an inherited sphingolipidosis characterized by progressive neurological deterioration and early mortality. The symptomatology and disease progression of NP-C are markedly affected by the age at onset of neurological manifestations, and categorization into early-infantile, late-infantile, juvenile, adolescent/adult neurological onset forms can aid evaluation of disease course and responses to therapy. Here, we review current information on the detection, diagnosis, monitoring and treatment of NP-C, with a focus on the adolescent/adult-onset form. A recent analysis indicated that the combined incidence of NP-C related to NPC1 gene mutations (NPC1) and NP-C related to NPC2 gene mutations (NPC2) is approximately 1 case in every 89 000 live births. In particular, late-onset phenotypes might well provide a greater contribution to the overall incidence than has previously been reported. Some neuropathological features in NP-C are held in common with other advanced age-onset diseases such as Alzheimer's disease. Visceral symptoms such as splenomegaly are frequently asymptomatic in patients with adolescent/adult-onset NP-C, and are only occasionally detected during routine ultrasound assessments. In contrast, most patients with adolescent/adult-onset exhibit some degree of slowly progressive, non-disease-specific movement disorders (e.g. cerebellar ataxia), and/or more pathognomonic neurological signs such as vertical supranuclear gaze palsy. An increasing number of adolescent/adult-onset cases have been reported following initial recognition of cognitive impairment and/or psychiatric signs. The recent development and implementation of new clinical screening tools (e.g. the NP-C suspicion index) and biomarkers (e.g. plasma oxysterols) should help identify patients who warrant further investigation and possible treatment.

    Full Text Available From 5% to 10% of diabetic patients have type 1 diabetes. Here we describe three cases of adult-onset type 1 diabetes in pregnancy treated at our clinic between 2009 and 2012. Two patients came for specialist examination during pregnancy, the third after pregnancy. These women had no prior overt diabetes and shared certain characteristics, that is, no family diabetes history, age over 35, normal prepregnancy BMI, need for insulin therapy as of the early weeks of pregnancy, and high-titer anti-GAD antibody positivity. The patients had persistent diabetes after delivery, suggesting that they developed adult-onset type 1 diabetes during pregnancy. About 10% of GDM patients become pancreatic autoantibody positive and the risk of developing overt diabetes is higher when two or more autoantibodies are present (particularly GAD and ICA. GAD-Ab shows the highest sensitivity for type 1 diabetes prediction. We need to bear in mind that older patients might conceivably develop an adult-onset type 1 diabetes during or after pregnancy. So we suggest that women with GDM showing the described clinical features shall be preferably tested for autoimmunity. Pregnant patients at risk of type 1 diabetes should be identified to avoid the maternal and fetal complications and the acute onset of diabetes afterwards.

    Full Text Available Adult-onset hemophagocytic lymphohistiocytosis (HLH has features that are distinct from that of HLH in pediatric patients. The clinical records at the Japanese Red Cross Kumamoto Hospital were reviewed. We retrospectively analyzed 34 patients who fulfilled the diagnostic criteria of HLH-2004. The median age of patients was 60.0 (range 15-86. Underlying diseases were diagnosed in 17 patients. They consisted of malignant lymphoma (n=3, other neoplastic disease (n=3, viral infection (n=4, collagen vascular disease (n=3, Kikuchi’s disease (n=3 and drug (n=1. Underlying diseases were not diagnosed in 17 patients despite examination. The treatments were steroids (n=18, dexamethasone + cyclosporine A (CSA + etoposide (n=4, multidrug chemotherapy (n=2, steroids and CSA (n=3. Eleven patients died during observation. In a multivariate analysis, the significant predictor for death was age at onset (hazard ratio, 1.22; 95%CI, 1.02-1.44; P=0.027. Autopsy was performed in 4 cases, but the underlying disease remained unknown in 3 of those cases. Adult-onset HLH has high diversity and various outcomes. The mechanism of adult-onset HLH is not fully understood and further research is required.

    Full Text Available Environmental compounds can promote epigenetic transgenerational inheritance of adult-onset disease in subsequent generations following ancestral exposure during fetal gonadal sex determination. The current study examined the ability of dioxin (2,3,7,8-tetrachlorodibenzo[p]dioxin, TCDD to promote epigenetic transgenerational inheritance of disease and DNA methylation epimutations in sperm. Gestating F0 generation females were exposed to dioxin during fetal day 8 to 14 and adult-onset disease was evaluated in F1 and F3 generation rats. The incidences of total disease and multiple disease increased in F1 and F3 generations. Prostate disease, ovarian primordial follicle loss and polycystic ovary disease were increased in F1 generation dioxin lineage. Kidney disease in males, pubertal abnormalities in females, ovarian primordial follicle loss and polycystic ovary disease were increased in F3 generation dioxin lineage animals. Analysis of the F3 generation sperm epigenome identified 50 differentially DNA methylated regions (DMR in gene promoters. These DMR provide potential epigenetic biomarkers for transgenerational disease and ancestral environmental exposures. Observations demonstrate dioxin exposure of a gestating female promotes epigenetic transgenerational inheritance of adult onset disease and sperm epimutations.

  19. The Need for Improved Detection and Management of Adult-Onset Hearing Loss in Australia

    2013-01-01

    Full Text Available Adult-onset hearing loss is insidious and typically diagnosed and managed several years after onset. Often, this is after the loss having led to multiple negative consequences including effects on employment, depressive symptoms, and increased risk of mortality. In contrast, the use of hearing aids is associated with reduced depression, longer life expectancy, and retention in the workplace. Despite this, several studies indicate high levels of unmet need for hearing health services in older adults and poor use of prescribed hearing aids, often leading to their abandonment. In Australia, the largest component of financial cost of hearing loss (excluding the loss of well-being is due to lost workplace productivity. Nonetheless, the Australian public health system does not have an effective and sustainable hearing screening strategy to tackle the problem of poor detection of adult-onset hearing loss. Given the increasing prevalence and disease burden of hearing impairment in adults, two key areas are not adequately met in the Australian healthcare system: (1 early identification of persons with chronic hearing impairment; (2 appropriate and targeted referral of these patients to hearing health service providers. This paper reviews the current literature, including population-based data from the Blue Mountains Hearing Study, and suggests different models for early detection of adult-onset hearing loss.

    Multiple sclerosis can affect pediatric patients. Our aim was to compare characteristics between pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanic Americans. This was a cross-sectional analysis of 363 Hispanic American multiple scleroses cases; demographic and clinical characteristics were analyzed. A total of 110 Hispanic patients presented with multiple sclerosis before age 18 and 253 as adult multiple sclerosis. The most common presenting symptoms for both was optic neuritis. Polyfocal symptoms, seizures, and cognitive symptoms at presentation were more prevalent in pediatric-onset multiple sclerosis (P ≤ .001). Transverse myelitis was more frequent in adult-onset multiple sclerosis (P ≤ .001). Using multivariable analysis, pediatric-onset multiple sclerosis (adjusted odds ratio, 0.3OR 95% confidence interval 0.16-0.71, P = .004) and being US born (adjusted odds ratio, 0.553, 95% confidence interval 0.3-1.03, P = .006) were less likely to have severe ambulatory disability. Results suggest that pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanics have differences that could be important for treatment and prognosis. PMID:27021143

  2. Radiographic abnormalities of the wrist in adult-onset still disease: Comparison with juvenile chronic arthritis and rheumatoid arthritis

    International Nuclear Information System (INIS)

    Pericapitate involvement of the wrist has been described as characteristic of adult-onset Still disease, a relatively rare disorder that is often diagnosed by exclusion after extensive and frequently invasive tests. To evaluate the diagnostic value of carpal radiography in cases of adult-onset Still disease, a retrospective blinded analysis of 48 patients, 16 each with adult-onset Still disease, juvenile chronic arthritis, and rheumatoid arthritis, was performed. Pericapitate articular alterations without radiocarpal involvement were found to be frequent in the setting of adult-onset Still disease but distinctly unusual among patients with rheumatoid arthritis. In juvenile chronic arthritis, severe pericapitate involvement was frequent, but generally occurred in conjunction with radiocarpal joint abnormalities

    We report a patient with a clinical picture of suggestive for adult-onset Still's Disease (ASOD) due to Bartonella infection. A 42-year-old immunocompetent man was admitted with fever, rash, arthralgia and sore throat. As his clinical picture suggested ASOD except unusual skin manifestation, we treated him on steroid and ibuprofen. His fever and constitutional symptoms responded immediately within 24hrs of commencing therapy, yet rash and leukocytosis remained. Meanwhile, Bartonella infection was proved by culture of bone marrow. Minocyclin treatment started combined with hydroxychloroquine sulfate and the patient discharged with overall improvement.

    Myotonic dystrophy type 1 (DM1) has a wide phenotypic spectrum and potentially may affect central nervous system with mild to severe involvement. Our aim was to investigate grey matter (GM) and white matter (WM) structural alterations in a sample of adult-onset DM1 patients and to evaluate relationship with clinical and cognitive variables. Thirty DM1 patients underwent neuropsychological investigation and 3T-MRI protocol. GM and WM changes were evaluated calculating brain parenchymal fraction (BPF), voxel-based morphometry (VBM), white matter lesion load (LL% and Fazekas scale) and tract based spatial statistical (TBSS). Patients showed main impairment in tests exploring executive and mnesic domains with visuo-spatial involvement, significantly related to BPF. VBM revealed clusters of widespread GM reduction and TBSS revealed areas of decreased fractional anisotropy (FA) and increased radial diffusivity (RD), mean diffusivity (MD) and axial diffusivity (AD) in patients compared to a group of matched healthy controls. Multiple regression analyses showed areas of significant negative relationship between left temporal atrophy and verbal memory, between RD and mnesic and visuo-spatial cognitive domains, and between AD and verbal memory. TBSS results indicate that the involvement of normal appearance WM, beyond the signal changes detected with conventional MR imaging (Fazekas scale and LL%), was associated with neuropsychological deficit. These data suggest that disrupted complex neuronal networks can underlie cognitive-behavioural dysfunctions in DM1. PMID:27437180

    Full Text Available Pica has been considered as the ingestion of inedible substances or atypical food combinations. Pica has been reported widely in pediatric age group and often found to be co existing with obsessive compulsive or major depressive disorder. Reports of pica in elderly age group are relatively uncommon and rarely does it have an adult onset. In this article we present a case of adult onset pica. A young lady with unusual sensation in her abdomen was found to consume iron nails over years and there was history of dyspareunia since her marriage three months back. On query it was known that the lady is having same sex relationship over years. There unique conglomeration of cultural, psychodynamic and physiological determinants which together is responsible for this unusual habit of this lady. Moreover the onset of the disease at a late age and different psychodynamic issues make the case all the more interesting. Whether the pica is an eating disorder or obsessive compulsive disorder is still controversial. Pica has been mentioned in Diagnostic and Statistical Manual IV TR. The present case report warrants the need to look into this entity more closely with regards to its occurrence and etiology.

    Objective: To identify the genetic defect for adult-onset primary lateral sclerosis (PLS) in a family with 5 patients. Methods: Whole-exome sequencing was performed to identify the shared genetic variants in 3 affected members in a PLS family with 5 affected individuals. Sanger sequencing was used for validation of the variants and for cosegregation analysis. Mitochondrial activity for both patients and unaffected siblings was measured using a SeaHorse metabolic analyzer. Results: Whole-exome sequencing and subsequent cosegregation analysis demonstrated that compound heterozygous missense variants L695P and I743T in SPG7 were the only mutations cosegregating with the disease in an autosomal recessive fashion in this family. The parents and siblings are genetically heterozygous and clinically unaffected. Functional studies suggested that the PLS-associated SPG7 mutants affect mitochondrial function when glucose is reduced. Conclusions: Compound heterozygote mutations in SPG7 are associated with adult-onset PLS, extending the spectrum of SPG7-linked neurologic diseases. Patients with the PLS phenotype should have genetic testing for paraplegin, especially when the condition is familial. PMID:27123479

    Many non-communicable diseases (NCDs) are largely preventable via behaviour change and healthy lifestyle, which may be best established during childhood. This study sought insights into Chinese new immigrant mothers' perceptions about adult-onset NCDs prevention during childhood. Twenty-three semi-structured interviews were carried out with new immigrant mothers from mainland China who had at least one child aged 14 years or younger living in Hong Kong. Interviews were audio taped, transcribed and analysed using a Grounded Theory approach. The present study identified three major themes: perceived causes of adult NCDs, beliefs about NCDs prevention and everyday health information practices. Unhealthy lifestyle, contaminated food and environment pollution were perceived as the primary causes of adult NCDs. Less than half of the participants recognized that parents had responsibility for helping children establish healthy behaviours from an early age to prevent diseases in later life. Most participants expressed helplessness about chronic diseases prevention due to lack of knowledge of prevention, being perceived as beyond individual control. Many participants experienced barriers to seeking health information, the most common sources of health information being interpersonal conversation and television. Participants' everyday information practice was passive and generally lacked awareness regarding early prevention of adult-onset NCDs. Updated understanding of this issue has notable implications for future health promotion interventions. PMID:24842077

    Full Text Available A 50-year-old female presented with fever, symmetrical arthralgias, rash, painful oral ulcerations and alopecia since 8 weeks. Examination showed mild hepatospleenomegaly. Investigations revealed leucocytosis, neutrophilia, elevated sedimentation rate and raised ferritin levels (3850 ng/ml. Computerized tomography (CT abdomen showed hepatospleenomegaly, mild ascitis and mild bilateral pleural-effusion. After ruling out occult infections, tuberculosis, malignancies and autoimmune diseases by appropriate investigations, and due to raised ferritin levels, adult onset stills disease (AOSD was diagnosed. Patient responded to oral steroids initially, but after 7 days developed severe abdominal pain. Repeat CT showed multiple enlarged, necrotic and matted retroperitoneal lymph nodes with caseating granuloma on histopathology suggesting tuberculosis. Patient was given four-drug anti-tubercular treatment and she improved. Thus our patient of occult abdominal tuberculosis with reactive arthritis (Poncet′s disease presented with hyperferritinemia mimicking AOSD. We postulate that extreme hyperferritinemia can be seen in tuberculosis and tuberculosis must be conclusively ruled out before diagnosing AOSD in tropics.

    Leigh syndrome is a mitochondrial disease caused by mutations in different genes, including ATP6A for which no known therapy is available. We report a case of adult-onset Leigh syndrome with response to immunotherapy. A twenty year-old woman with baseline learning difficulties was admitted with progressive behavioral changes, diplopia, headaches, bladder incontinence, and incoordination. Brain MRI and PET scan showed T2 hyperintensity and increased uptake in bilateral basal ganglia, respectively. Autoimmune encephalitis was suspected and she received plasmapheresis with clinical improvement. She was readmitted 4 weeks later with dysphagia and aspiration pneumonia. Plasmapheresis was repeated with resolution of her symptoms. Given the multisystem involvement and suggestive MRI changes, genetic testing was done, revealing a homoplasmic T9176C ATPase 6 gene mtDNA mutation. Monthly IVIG provided clinical improvement with worsening when infusions were delayed. Leigh syndrome secondary to mtDNA T9176C mutations could have an autoimmune mechanism that responds to immunotherapy. PMID:27408822

    High body mass index (BMI) (calculated as weight (kg)/height (m)2) is associated with increased asthma risk, but uncertainty persists about the role of physical activity. We estimated the independent and joint associations of hypothetical interventions on BMI and physical activity with the risk of adult-onset asthma in 76,470 asthma-free women from the Nurses’ Health Study who were followed between 1988 and 1998. Information about asthma, BMI, physical activity, and other factors was updated every 2 years. We used the parametric g-formula to estimate the 10-year asthma risk in the following 4 scenarios: no intervention, 5% BMI reduction in a 2-year period for those who were overweight or obese, at least 2.5 hours/week of moderate-to-vigorous physical activity, and both of the previous 2 interventions. At baseline, women had a mean age of 55 (standard deviation, 7) years and a mean BMI of 25.4 (standard deviation, 4.8). Median time spent in physical activity was 0.7 hours/week. During follow-up, 1,146 women developed asthma. The 10-year asthma risk under no intervention was 1.5%. Compared with no intervention, the population risk ratios were 0.96 (95% confidence interval (CI): 0.93, 0.99) under the BMI intervention, 0.96 (95% CI: 0.81, 1.10) under the physical activity intervention, and 0.92 (95% CI: 0.78, 1.06) under the joint intervention. Interventions on BMI and physical activity may have a modest impact on the risk of adult-onset asthma in this population of US women. PMID:24107616

    Obesity has reached epidemic proportions worldwide. Several animal models of obesity exist, but studies are lacking that compare traditional lard-based high fat diets (HFD) to "Cafeteria diets" (CAF) consisting of nutrient poor human junk food. Our previous work demonstrated the rapid and severe obesogenic and inflammatory consequences of CAF compared to HFD including rapid weight gain, markers of Metabolic Syndrome, multi-tissue lipid accumulation, and dramatic inflammation. To identify potential mediators of CAF-induced obesity and Metabolic Syndrome, we used metabolomic analysis to profile serum, muscle, and white adipose from rats fed CAF, HFD, or standard control diets. Principle component analysis identified elevations in clusters of fatty acids and acylcarnitines. These increases in metabolites were associated with systemic mitochondrial dysfunction that paralleled weight gain, physiologic measures of Metabolic Syndrome, and tissue inflammation in CAF-fed rats. Spearman pairwise correlations between metabolites, physiologic, and histologic findings revealed strong correlations between elevated markers of inflammation in CAF-fed animals, measured as crown like structures in adipose, and specifically the pro-inflammatory saturated fatty acids and oxidation intermediates laurate and lauroyl carnitine. Treatment of bone marrow-derived macrophages with lauroyl carnitine polarized macrophages towards the M1 pro-inflammatory phenotype through downregulation of AMPK and secretion of pro-inflammatory cytokines. Results presented herein demonstrate that compared to a traditional HFD model, the CAF diet provides a robust model for diet-induced human obesity, which models Metabolic Syndrome-related mitochondrial dysfunction in serum, muscle, and adipose, along with pro-inflammatory metabolite alterations. These data also suggest that modifying the availability or metabolism of saturated fatty acids may limit the inflammation associated with obesity leading to Metabolic

    Full Text Available Purpose: We report a case of adult-onset foveomacular vitelliform dystrophy (AOFVD complicated with atrophic involution and subsequent choroidal neovascularization (CNV and treated with intravitreal ranibizumab. Design: Case Report Methods: A 71-year-old woman diagnosed with AOFVD experienced a progression of the vitelliform lesion to the atrophic stage in her left eye immediately after cataract surgery. Best corrected visual acuity (BCVA decreased from 0.5 to 0.16. Ten months later, the patient was referred with new worsening of her visual acuity (0.05 and metamorphopsia. The spectral-domain optical coherence tomography (SD-OCT confirmed the presence of type 2 CNV next to the atrophic area. The patient was treated with 2 monthly injections of ranibizumab. Results: SD-OCT images improved significantly and her BCVA increased to 0.20 associated with subjective improvement of metamorphopsia. Conclusion: Ranibizumab may be effective for CNV in patients with AOFVD.

  17. Proteomics analysis of human obesity reveals the epigenetic factor HDAC4 as a potential target for obesity.

    Full Text Available Sedentary lifestyle and excessive energy intake are prominent contributors to obesity; a major risk factors for the development of insulin resistance, type 2 diabetes and cardiovascular diseases. Elucidating the molecular mechanisms underlying these chronic conditions is of relevant importance as it might lead to the identification of novel anti-obesity targets. The purpose of the current study is to investigate differentially expressed proteins between lean and obese subjects through a shot-gun quantitative proteomics approach using peripheral blood mononuclear cells (PBMCs extracts as well as potential modulation of those proteins by physical exercise. Using this approach, a total of 47 proteins showed at least 1.5 fold change between lean and obese subjects. In obese, the proteomic profiling before and after 3 months of physical exercise showed differential expression of 38 proteins. Thrombospondin 1 (TSP1 was among the proteins that were upregulated in obese subjects and then decreased by physical exercise. Conversely, the histone deacetylase 4 (HDAC4 was downregulated in obese subjects and then induced by physical exercise. The proteomic data was further validated by qRT-PCR, Western blot and immunohistochemistry in both PBMCs and adipose tissue. We also showed that HDAC4 levels correlated positively with maximum oxygen consumption (VO2 Max but negatively with body mass index, percent body fat, and the inflammatory chemokine RANTES. In functional assays, our data indicated that ectopic expression of HDAC4 significantly impaired TNF-α-dependent activation of NF-κB, establishing thus a link between HDAC4 and regulation of the immune system. Together, the expression pattern of HDAC4 in obese subjects before and after physical exercise, its correlation with various physical, clinical and metabolic parameters along with its inhibitory effect on NF-κB are suggestive of a protective role of HDAC4 against obesity. HDAC4 could therefore represent

    Full Text Available Abstract Background HMO databases offer an opportunity for community based epidemiologic studies of asthma incidence, etiology and treatment. The incidence of asthma in HMO populations and the utility of HMO data, including use of computerized algorithms and manual review of medical charts for determining etiologic factors has not been fully explored. Methods We identified adult-onset asthma, using computerized record searches in a New England HMO. Monthly, our software applied exclusion and inclusion criteria to identify an "at-risk" population and "potential cases". Electronic and paper medical records from the past year were then reviewed for each potential case. Persons with other respiratory diseases or insignificant treatment for asthma were excluded. Confirmed adult-onset asthma (AOA cases were defined as those potential cases with either new-onset asthma or reactivated mild intermittent asthma that had been quiescent for at least one year. We validated the methods by reviewing charts of selected subjects rejected by the algorithm. Results The algorithm was 93 to 99.3% sensitive and 99.6% specific. Sixty-three percent (n = 469 of potential cases were confirmed as AOA. Two thirds of confirmed cases were women with an average age of 34.8 (SD 11.8, and 45% had no evidence of previous asthma diagnosis. The annualized monthly rate of AOA ranged from 4.1 to 11.4 per 1000 at-risk members. Physicians most commonly attribute asthma to infection (59% and allergy (14%. New-onset cases were more likely attributed to infection, while reactivated cases were more associated with allergies. Medical charts included a discussion of work exposures in relation to asthma in only 32 (7% cases. Twenty-three of these (72% indicated there was an association between asthma and workplace exposures for an overall rate of work-related asthma of 4.9%. Conclusion Computerized HMO records can be successfully used to identify AOA. Manual review of these records is

    Despite progressive disability in sporadic adult-onset ataxia (SAOA), little is known about patients' assessment of their ataxic disorder and its impact on health-related quality of life (Hr-QoL). This study investigated Hr-QoL by means of the following self-administered scales: Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, Beck Depression Inventory (BDI), and the Medical Outcome Study Short Form (SF-36). Twenty-two unselected ataxia patients were included. Sleep-related complaints were found in 9 (41%) of 22 and symptoms of depression in 6 (38%) of 16 patients. Compared to a large german control group, SAOA patients had lower scores in all SF-36 dimensions except for bodily pain. The greatest impairment was found in the domain physical functioning, followed by the domains social functioning and role limitations (emotional problems). There was a significant negative correlation of all nonmotor SF-36 dimensions with the BDI score. Walking aid dependency was significantly correlated with poorer health status perception in several motor and nonmotor domains. In addition, impaired sleep quality was correlated with an impaired general health perception and with bodily pain. The study demonstrates a great impact of SAOA on Hr-QoL. Adequate treatment of depression, motor disability, and impaired sleep quality is essential to improve Hr-QoL in ataxic patients. PMID:17149704

  3. Genes and Pathways Involved in Adult Onset Disorders Featuring Muscle Mitochondrial DNA Instability

    Full Text Available Replication and maintenance of mtDNA entirely relies on a set of proteins encoded by the nuclear genome, which include members of the core replicative machinery, proteins involved in the homeostasis of mitochondrial dNTPs pools or deputed to the control of mitochondrial dynamics and morphology. Mutations in their coding genes have been observed in familial and sporadic forms of pediatric and adult-onset clinical phenotypes featuring mtDNA instability. The list of defects involved in these disorders has recently expanded, including mutations in the exo-/endo-nuclease flap-processing proteins MGME1 and DNA2, supporting the notion that an enzymatic DNA repair system actively takes place in mitochondria. The results obtained in the last few years acknowledge the contribution of next-generation sequencing methods in the identification of new disease loci in small groups of patients and even single probands. Although heterogeneous, these genes can be conveniently classified according to the pathway to which they belong. The definition of the molecular and biochemical features of these pathways might be helpful for fundamental knowledge of these disorders, to accelerate genetic diagnosis of patients and the development of rational therapies. In this review, we discuss the molecular findings disclosed in adult patients with muscle pathology hallmarked by mtDNA instability.

    Full Text Available Adult onset Still’s disease (AOSD is a rare inflammatory disorder of unknown etiology that usually affects young adults. Very few patients older than 70-year-old have been reported. Clinical features include quotidian fevers, arthralgias, arthritis, pharyngitis, lymphadenopathy and an evanescent rash. AOSD should be considered in the differential diagnosis of fever of unknown origin. Early diagnosis is often difficult since it is a diagnosis of exclusion and the presence of infectious, neoplastic and autoimmune conditions needs to be ruled out before the diagnosis is made. No specific laboratory tests are available to aid in the diagnosis of AOSD. As a result, a set of diagnostic criteria that define the clinical features of this condition, termed the Yamaguchi criteria, have been most commonly used to establish the diagnosis. We describe the case of a 72-year-old Caucasian male with past medical history significant for generalized anxiety disorder, depression, BPH, and hypertriglyceridemia, who presented to a tertiary institution complaining of profound generalized weakness and weight loss that started three weeks prior to presentation. Initial laboratory studies showed leukocytosis, elevated ESR, CRP, ferritin and liver dysfunction. Cultures, ANA and rheumatoid factor studies were negative. The patient underwent further extensive workup that excluded the presence of infectious, neoplastic and autoimmune disorders and was subsequently diagnosed with AOSD and new onset diabetes mellitus. For the management of AOSD he was started on prednisone with significant improvement in markers of inflammation, symptoms and level of function.

  5. Effects of Aging and Adult-Onset Hearing Loss on Cortical Auditory Regions

    2016-01-01

    Hearing loss is a common feature in human aging. It has been argued that dysfunctions in central processing are important contributing factors to hearing loss during older age. Aging also has well documented consequences for neural structure and function, but it is not clear how these effects interact with those that arise as a consequence of hearing loss. This paper reviews the effects of aging and adult-onset hearing loss in the structure and function of cortical auditory regions. The evidence reviewed suggests that aging and hearing loss result in atrophy of cortical auditory regions and stronger engagement of networks involved in the detection of salient events, adaptive control and re-allocation of attention. These cortical mechanisms are engaged during listening in effortful conditions in normal hearing individuals. Therefore, as a consequence of aging and hearing loss, all listening becomes effortful and cognitive load is constantly high, reducing the amount of available cognitive resources. This constant effortful listening and reduced cognitive spare capacity could be what accelerates cognitive decline in older adults with hearing loss. PMID:27242405

    The administration of drugs to inhibit metabolic pathways not only reduces the risk of obesity-induced diseases in humans but may also hamper the replication of different viral pathogens. In order to investigate the value of the US Food and Drug Administration-approved anti-obesity drug orlistat in view of its anti-viral activity against different human-pathogenic viruses, several anti-viral studies, electron microscopy analyses as well as fatty acid uptake experiments were performed. The results indicate that administrations of non-cytotoxic concentrations of orlistat reduced the replication of coxsackievirus B3 (CVB3) in different cell types significantly. Moreover, orlistat revealed cell protective effects and modified the formation of multi-layered structures in CVB3-infected cells, which are necessary for viral replication. Lowering fatty acid uptake from the extracellular environment by phloretin administrations had only marginal impact on CVB3 replication. Finally, orlistat reduced also the replication of varicella-zoster virus moderately but had no significant influence on the replication of influenza A viruses. The data support further experiments into the value of orlistat as an inhibitor of the fatty acid synthase to develop new anti-viral compounds, which are based on the modulation of cellular metabolic pathways.

    PurposeTo report the association and prevalence of reticular pseudodrusen (RPD) in eyes with newly presenting adult onset foveomacular vitelliform dystrophy (AFVD). To compare the strength of association with other pathologies resulting from dysfunction of the choroid-Bruch's membrane-retinal pigment epithelium (RPE) complex, including eyes with geographic atrophy (GA) and angioid streaks.MethodsRetrospective single-centre review of all consecutive newly presenting AFVD. Multimodal imaging with spectral domain optical coherence tomography, fundus photographs, red-free/blue light images, and fundus fluorescein angiograms were graded for the presence of RPD. For comparison, all consecutive newly presenting cases of GA and eyes with angioid streaks were studied.ResultsFifteen (15) patients were identified with AFVD (mean age of 77.3 years; 73.3% female). Mean age of patients with AFVD and RPD was 80.5 years (SD 3.7), whereas that of patients with AFVD without RPD was 75.1 years (SD 7.0). This age difference did not reach statistical significance, P=0.1. Six (40%) had identifiable RPD; being a bilateral finding in 100% of patients. No males with AFVD and RPD were identified. A total of 92 eyes presented with GA. Twenty-three (23) of these (25.0%) had RPD. Twelve (12) patients presented with identifiable angioid streaks, with 4 (36.4%) having RPD.ConclusionRPD are a frequent finding in eyes with newly presenting AFVD; not being restricted to AMD, but a finding common among diseases where pathophysiological mechanisms involve damage to Bruch's membrane and the RPE, whether genetic or degenerative. Our study supports the concept that they occur with high but variable frequencies in eyes with various pathologies. PMID:27034200

    Full Text Available Background: Actinic prurigo (AP is a chronic, pruritic skin condition caused by an abnormal reaction to sunlight. Aims: The aim of this study is to determine the clinical characteristics of AP in patients attending the National Skin Centre, Singapore, from 1 st January 1999 to 30 th June 2008. Methods: Cases of AP diagnosed from 1 st January 1999 to 30 th June 2008 were retrieved from the center′s electronic medical records and analyzed. Results: A total of 11 patients were diagnosed with AP. The mean age at diagnosis was 52 years. There were 9 (82% Chinese and 2 (18% Malay patients. Nine (82% were male and 2 (18% were female. The most commonly affected areas were the face, forearms, and hands (72%. Phototesting showed reduced minimal erythema dose (MED to ultraviolet A (UVA in 5 (46% patients, both UVA and ultraviolet B (UVB in 4 (36% patients and UVB in 1 (9% patient. Seven (64% patients reported partial improvement after treatment with a combination of topical corticosteroids and sunscreens. Four (36% patients received systemic therapy with partial response. Conclusion: Adult-onset AP is more common in the Asian population, with a male predominance. The face, forearms, and hands are the most commonly affected areas. The absence of mucosal involvement is also a distinguishing feature between the Asian and Caucasian population. Close to half of the patients have reduced MED to UVA on phototesting. The prognosis for AP is poor as it tends to run a chronic course with suboptimal response to treatment.

    Full Text Available Adult-onset hypothyroidism induces a variety of impairments on hippocampus- dependent neurocognitive functioningin which many synaptic proteins in hippocampus neurons are involved. Here, we observed the effect of adult-onset hypothyroidism on the expression of syntaxin-1 and munc-18 in the dorsal hippocampus and whether the altered proteins could be restored by levothyroxine (T4 treatment. All rats were separated into 4 groups randomly: hypothyroid group, 5μg T4/100 g body weight (BW treated group, 20 μg T4/100g BW treated group and control group. The radioimmunoassay kits were applied to assay the levels of serum T3 and T4, and the levels of syntaxin-1 and munc-18 in hippocampus were assessed by immunohistochemistry and Western blot. Both analysis corroborated that syntaxin-1 in the hypothyroid group was significantly higher. Munc-18 was lower in four layers of CA3 and dentate gyrus by immunohistochemistry. After two weeks of treatment with 5 μg T4/100g BW for hypothyroidism, syntaxin-1 levels were completely restored, whereas the recovery of munc-18 only located in two of the four impaired layers. Twenty μg T4/100g BW treatment normalized munc-18 levels. These data suggested that adult-onset hypothyroidism induced increment of syntaxin-1 and decrement of munc-18 in the dorsal hippocampus, which could be restored by T4 treatment. Larger dosage of T4 caused more effective restorations.

    Objective: This study examined the proteomic profile of the hypothalamus in mice exposed to a high-fat diet (HFD) or with the anorexia of acute illness. This comparison could provide insight on the effects of these two opposite states of energy balance on appetite regulation. Methods: Four to six-week-old male C56BL/6J mice were fed a normal (control 1 group; n=7) or a HFD (HFD group; n=10) for 8 weeks. The control 2 (n=7) and lipopolysaccharide (LPS) groups (n=10) were fed a normal diet for 8 weeks before receiving an injection of saline and LPS, respectively. Hypothalamic regions were analysed using a quantitative proteomics method based on a combination of techniques including iTRAQ stable isotope labeling, orthogonal two-dimensional liquid chromatography hyphenated with nanospray ionization and high-resolution mass spectrometry. Key proteins were validated with quantitative PCR. Results: Quantitative proteomics of the hypothalamous regions profiled a total of 9249 protein groups (q<0.05). Of these, 7718 protein groups were profiled with a minimum of two unique peptides for each. Hierachical clustering of the differentiated proteome revealed distinct proteomic signatures for the hypothalamus under the HFD and LPS nutritional conditions. Literature research with in silico bioinformatics interpretation of the differentiated proteome identified key biological relevant proteins and implicated pathways. Furthermore, the study identified potential pharmacologic targets. In the LPS groups, the anorexigen pro-opiomelanocortin was downregulated. In mice with obesity, nuclear factor-κB, glycine receptor subunit alpha-4 (GlyR) and neuropeptide Y levels were elevated, whereas serotonin receptor 1B levels decreased. Conclusions: High-precision quantitative proteomics revealed that under acute systemic inflammation in the hypothalamus as a response to LPS, homeostatic mechanisms mediating loss of appetite take effect. Conversely, under chronic inflammation in the

    Previously, we found that C57BL/6J (B6) mice are more prone to develop obesity than PWK mice. In addition, we analyzed reciprocal crosses between these mice and found that (PWK × B6) F1 mice, which have B6 fathers, are more likely to develop dietary obesity than (B6 × PWK) F1 mice, which have B6 mothers. These results suggested that diet-induced obesity is paternally transmitted. In this study, we performed transcriptome analysis of adipose tissues of B6, PWK, (PWK × B6) F1, and (B6 × PWK) F1 mice using next-generation sequencing. We found that paternal transmission of diet-induced obesity was correlated with genes involved in adipose tissue inflammation, metal ion transport, and cilia. Furthermore, we analyzed the imprinted genes expressed in white adipose tissue (WAT) and obesity. Expression of paternally expressed imprinted genes (PEGs) was negatively correlated with body weight, whereas expression of maternally expressed imprinted genes (MEGs) was positively correlated. In the obesity-prone B6 mice, expression of PEGs was down-regulated by a high-fat diet, suggesting that abnormally low expression of PEGs contributes to high-fat diet-induced obesity in B6 mice. In addition, using single-nucleotide polymorphisms that differ between B6 and PWK, we identified candidate imprinted genes in WAT. PMID:26868178

    Clinical and animal studies indicate that intrauterine growth restriction (IUGR) following uteroplacental insufficiency (UPI) reduces nephron number and predisposes toward renal insufficiency early in life and increased risk of adult-onset hypertension. In this study, we hypothesized that the inducible enzyme cyclooxygenase-2 (COX-2), a pivotal protein in nephrogenesis, constitutes a mechanism through which UPI and subsequent glucocorticoid overexposure can decrease nephron number. We further hypothesized that UPI downregulates the key enzyme 11beta-hydroxysteroid dehydrogenase type 2 (11beta-HSD2), which converts corticosterone to inert 11-dehydrocorticosterone, thereby protecting both the glucocorticoid receptor (GR) and the mineralocorticoid receptor (MR) from the actions of corticosterone. Following bilateral uterine ligation on the pregnant rat, UPI significantly decreased renal COX-2, 11beta-HSD2, and GR mRNA and protein levels, but upregulated expression of MR at birth. At day 21 of life, 11beta-HSD2, GR, and also MR mRNA and protein levels were downregulated. UPI did not affect blood pressures (BP) at day 21 of life but significantly increased systolic BP in both genders at day 140. We conclude that in our animal model, UPI decreases fetal COX-2 expression during a period of active nephrogenesis in the IUGR rat, which is also characterized by decreased nephron number and adult-onset hypertension.

    ADAM33, a member of the ADAM (a disintegrin and metalloprotease) gene family, is an asthma susceptibility gene originally identified by positional cloning. In the present study, we investigated the possible association of five single-nucleotide polymorphisms (SNPs) in the ADAM33 (rs511898, rs528557, rs44707, rs597980 and rs2787094) with adult-onset asthma in an Indian population. The study included 175 patients with mild intermittent ($n = 44$), mild persistent ($n = 108$) or moderate persistent ($n = 23$) subgroups of asthma, and 253 nonasthmatic control individuals. SNPs were genotyped with the help of restriction fragment length polymorphism polymerase chain reaction (RFLP-PCR) method, and data were analysed using chi-square test and logistic regression model. Bonferroni’s correction for multiple comparisons was applied for each hypothesis. Genotypes and allele frequencies of SNPs rs511898 and rs528557 were significantly associated with adult-onset asthma ($P = 0.010-\\lt 0.001$). A significant association of the homozygous mutant genotype and mutant alleles of SNPs rs2787094, rs44707 and rs597980 with the asthma was also observed ($P = 0.020-\\lt 0.001$). A positive association between asthma and haplotypes AGCCT, GGCCT, AGACT, GCAGT, GGACT, ACCCC and AGACC were also found ($P = 0.036-\\lt 0.001$, OR $= 2.07-8.49$). Haplotypes AGCGT, GCAGC, ACAGC, ACAGT, GGAGC and GGCGT appear to protect against asthma ($P = 0.013-\\lt 0.0001$, OR $= 0.34-0.10$). Our data suggest that ADAM33 gene polymorphisms serve as genetic risk factors for asthma in Indian adult population.

  3. Temporal discrimination thresholds in adult-onset primary torsion dystonia: an analysis by task type and by dystonia phenotype.

    2012-01-01

    Adult-onset primary torsion dystonia (AOPTD) is an autosomal dominant disorder with markedly reduced penetrance. Sensory abnormalities are present in AOPTD and also in unaffected relatives, possibly indicating non-manifesting gene carriage (acting as an endophenotype). The temporal discrimination threshold (TDT) is the shortest time interval at which two stimuli are detected to be asynchronous. We aimed to compare the sensitivity and specificity of three different TDT tasks (visual, tactile and mixed\\/visual-tactile). We also aimed to examine the sensitivity of TDTs in different AOPTD phenotypes. To examine tasks, we tested TDT in 41 patients and 51 controls using visual (2 lights), tactile (non-painful electrical stimulation) and mixed (1 light, 1 electrical) stimuli. To investigate phenotypes, we examined 71 AOPTD patients (37 cervical dystonia, 14 writer\\'s cramp, 9 blepharospasm, 11 spasmodic dysphonia) and 8 musician\\'s dystonia patients. The upper limit of normal was defined as control mean +2.5 SD. In dystonia patients, the visual task detected abnormalities in 35\\/41 (85%), the tactile task in 35\\/41 (85%) and the mixed task in 26\\/41 (63%); the mixed task was less sensitive than the other two (p = 0.04). Specificity was 100% for the visual and tactile tasks. Abnormal TDTs were found in 36 of 37 (97.3%) cervical dystonia, 12 of 14 (85.7%) writer\\'s cramp, 8 of 9 (88.8%) blepharospasm, 10 of 11 (90.1%) spasmodic dysphonia patients and 5 of 8 (62.5%) musicians. The visual and tactile tasks were found to be more sensitive than the mixed task. Temporal discrimination threshold results were comparable across common adult-onset primary torsion dystonia phenotypes, with lower sensitivity in the musicians.

    We sought to determine whether diffusion-tensor imaging (DTI) can detect in vivo axonal damage in the corticopontocerebellar pathway of patients with adult-onset ataxic neurodegenerative disease. Conventional MRI and DTI were performed on 18 patients with adult-onset ataxic neurodegenerative disease and 28 age-matched control subjects. Fractional anisotropy (FA) and the mean diffusivity (MD) were measured in the ventral, central, and dorsal pons, middle cerebellar peduncle (MCP) and internal capsule to evaluate corticopontocerebellar projection. Changes in FA and MD values were compared between patients and controls. Clinical disability was assessed according to the International Cooperative Ataxia Rating Scale (ICARS). The relationship between DTI measurements and ICARS was studied. Follow-up MRI was performed in five patients approximately 1 year later. FA values were significantly lower in the ventral and central portions of the pons, MCP, and internal capsules than in these areas in control subjects (P < 0.05) with the lower FA values correlating with poorer ICARS (r > -0.57, P < 0.05). MD values were elevated in these areas, but the differences were smaller than for the FA values. No relationship was observed between the MD and ICARS. In the five patients who underwent the follow-up study, there were significant decreases between the initial study and the follow-up DTI study for FA in the MCP and internal capsule (P < 0.05). DTI can demonstrate a degenerated corticopontocerebellar pathway in patients, and FA values can be correlated with ataxia severity. DTI may be a clinically useful tool as a quantitative surrogate marker for monitoring disease progression. (orig.)

    Niemann-Pick disease, type C (NP-C), is caused by NPC1 or NPC2 gene mutations. Progressive neurological, psychiatric, and visceral symptoms are characteristic. Here, we present cases of a brother (Case 1) and sister (Case 2) in their mid-20s with gait disturbance and psychosis. For the Case 1, neurological examination revealed dystonia, ataxia, vertical supranuclear-gaze palsy (VSGP), and global cognitive impairment. Case 2 showed milder, but similar symptoms, with cortical atrophy. Abdominal computed tomography showed hepatosplenomegaly in both cases. NPC1 gene sequencing revealed compound heterozygote for exon 9 (c.1552C>T [R518W]) and exon 18 (c.2780C>T [A927V]). Filipin-staining tests were also positive. When a young patient with ataxia or dystonia shows VSGP, NP-C should be considered. PMID:27366019

    β-Catenin (βcat) is a major downstream signaling node in canonical Wingless-related integration site (Wnt) signaling pathway, and its activity is crucial for canonical Wnt signal transduction. Wnt signaling has recently been implicated in the osteo-anabolic response to PTH, a potent calcium-regulating factor. We investigated whether βcat is essential for the anabolic action of intermittent PTH by generating male mice with adult-onset deletion of βcat in a subpopulation of bone cells (osteocytes and late-stage osteoblasts), treating them with an anabolic regimen of PTH, and measuring the skeletal responses. Male (10kb)Dmp1-CreERt2 transgenic mice that also harbored floxed loss-of-function βcat alleles (βcat(f/f)) were induced for Cre activity using tamoxifen, then injected daily with human PTH 1-34 (30 μg/kg) or vehicle for 5 weeks. Mice in which βcat was deleted showed either total lack of bone mineral density (BMD) gain, or BMD loss, and did not respond to PTH treatment. However, bone mass measurements in the trabecular compartment of the femur and spine revealed PTH-induced bone gain whether βcat was deleted or not. PTH-stimulated increases in periosteal and cancellous bone formation rates were not impaired by βcat deletion, but resorption markers and cortical porosity were significantly increased in induced mice, particularly induced mice treated with PTH. These results suggest that βcat is required for net-positive BMD effects of PTH therapy but that the anabolic effects per se of PTH treatment might not require osteocytic/osteoblastic βcat.

    Objective To determine if metabolically healthy obese (MHO) individuals have a different metabolic response to a standardized diet compared to lean healthy (LH) and metabolically unhealthy obese (MUO) individuals. Methods Thirty adults (35–70 yrs) were classified as LH, MHO, and MUO according to anthropometric and clinical measurements. Participants consumed a standardized high calorie meal (~1330 kcal). Blood glucose and insulin were measured at fasting, and 15, 30, 60, 90 and 120 min postprandially. Additional blood samples were collected for the targeted analysis of amino acids (AAs) and derivatives, and fatty acids (FAs). Results The postprandial response (i.e., area under the curve, AUC) for serum glucose and insulin were similar between MHO and LH individuals, and significantly lower than MUO individuals (p < 0.05). Minor differences were found in postprandial responses for AAs between MHO and MUO individuals, while three polyunsaturated FAs (linoleic acid, γ-linolenic acid, arachidonic acid) showed smaller changes in serum after the meal in MHO individuals compared to MUO. Fasting levels for various AAs (notably branched-chain AA) and FAs (e.g., saturated myristic and palmitic acids) were found to correlate with glucose and insulin AUC. Conclusion MHO individuals show preserved insulin sensitivity and a greater ability to adapt to a caloric challenge compared to MUO individuals. PMID:26274804

    INTRODUCTION: Neurocognitive functioning and other aspects of quality of life have become increasingly important in the clinical care of patients with glioma. While regular monitoring of neurocognitive functioning with thorough evaluations would be ideal for patients, this is often impractical due to time, cost, and resource considerations. Instead, a measure of self-reported cognitive symptoms can be administered to identify the patients who perceive themselves to be experiencing cognitive difficulties, allowing for rapid detection of patients in need. Recently, a self-report measure of neurocognitive functioning was developed to target the cognitive domains affected by cancer treatments. However, to our knowledge, studies of this questionnaire in adults have only included adult survivors of childhood cancers. METHODS: In the present study, 299 patients with adult-onset WHO Grade II-IV glioma completed the Childhood Cancer Survivor Study Neurocognitive Questionnaire. This 25-item measure has four subscales representing different cognitive functions: Task Efficiency, Emotional Tolerance, Organization, and Memory. RESULTS: Overall scores, primary areas of concern, and relationships with medical characteristics were identified. Subtest scores were: Task Efficiency T score (M = 42.8, SD = 15.9), Emotional Tolerance T score (M = 51.6, SD = 11.7), Organization T score (M = 48.6, SD = 11.7), and Memory T score (M = 44.0, SD = 15.3), demonstrating task efficiency to be the cognitive function of greatest concern. Individual item responses were then analyzed, with 188 patients (61.6%) endorsing the highest ranked item: "I have difficulty recalling things I had previously learned" (M = 0.81, SD = 0.74). Chi-square tests, t-tests, and regression were also performed, and these analyses identified statistically significant effects of tumor laterality, radiochemotherapy, recurrence, and KPS score (p < .05), but not tumor grade, on each of the four subscale scores.

    Mutations of the huntingtin protein (HTT) gene underlie both adult-onset and juvenile forms of Huntington’s disease (HD). HTT modulates mitotic spindle orientation and cell fate in mouse cortical progenitors from the ventricular zone. Using human embryonic stem cells (hESC) characterized as carrying mutations associated with adult-onset disease during pre-implantation genetic diagnosis, we investigated the influence of human HTT and of an adult-onset HD mutation on mitotic spindle orientation in human neural stem cells (NSCs) derived from hESCs. The RNAi-mediated silencing of both HTT alleles in neural stem cells derived from hESCs disrupted spindle orientation and led to the mislocalization of dynein, the p150Glued subunit of dynactin and the large nuclear mitotic apparatus (NuMA) protein. We also investigated the effect of the adult-onset HD mutation on the role of HTT during spindle orientation in NSCs derived from HD-hESCs. By combining SNP-targeting allele-specific silencing and gain-of-function approaches, we showed that a 46-glutamine expansion in human HTT was sufficient for a dominant-negative effect on spindle orientation and changes in the distribution within the spindle pole and the cell cortex of dynein, p150Glued and NuMA in neural cells. Thus, neural derivatives of disease-specific human pluripotent stem cells constitute a relevant biological resource for exploring the impact of adult-onset HD mutations of the HTT gene on the division of neural progenitors, with potential applications in HD drug discovery targeting HTT-dynein-p150Glued complex interactions.

    Multiple primitive intracranial tumors with different histological characteristics are uncommon. Although coexistence of a medulloblastoma with glial tumors has been reported in children, medulloblastoma is rarely found in adults, especially those older than 40 years of age. We present an extremely rare case of a medulloblastoma developing in a 40-year-old male undergoing maintenance chemotherapy for anaplastic astrocytoma for 21 months after radiotherapy. Initially, he complained of intractable epilepsy characterized by complex partial seizures. Magnetic resonance imaging (MRI) revealed a slightly enhanced mass lesion in the left insula region. He underwent subtotal removal of the tumor and it was histologically diagnosed as anaplastic astrocytoma. After 19 months of treatment with temozolomide (TMZ) and radiotherapy, he presented with vertigo and headache. A homogeneously enhanced mass had developed in the left cerebellar hemisphere. He received gross total resection of the second tumor, pathologically diagnosed as medulloblastoma. In conclusion, this is the first case report of an adult medulloblastoma coexisting with anaplastic astrocytoma. PMID:24101275

  12. Recurrent adult-onset hypophyseal Langerhans cell histiocytosis after radiotherapy: a case report

    Full Text Available Abstract Introduction Langerhans cell histiocytosis is a rare disease within the adult population, with very few cases reported as solitary hypophyseal lesions in adults. Of the reported cases, most have been treated successfully with surgery, radiotherapy, and/or chemotherapy. Radiotherapy has been thought to be curative at the relatively low dose of 20Gy. Here we report a case of recurrent hypophyseal Langerhans cell histiocytosis 9 months after radiotherapy with an interval period of symptomatic and radiographic response to therapy. Case presentation A 50-year-old Caucasian woman who had headaches, memory difficulties, and diabetes insipidus was found to have a 2.5cm suprasellar mass. Langerhans cell histiocytosis was diagnosed following stereotactic brain biopsy. Further workup revealed no other lesions. Initial radiation treatment succeeded in shrinking the tumor and relieving clinical symptoms temporarily; however, growth and recurrence of clinical symptoms was noted at 9 months. Re-irradiation was well tolerated and the patient had no acute side effects. Conclusion Isolated hypophyseal involvement by Langerhans cell histiocytosis in adults is a unique presentation of a rare disease. Although radiotherapy doses as low as 20Gy have been reported to offer control, this case demonstrates that higher doses may be warranted to ensure tumor control. With modern imaging and radiotherapy techniques higher doses should offer little increased more durable risk to surrounding critical structures.

    Background: Chronic stress resulting from experiences of racism may increase the incidence of adult-onset asthma through effects on the immune system and the airways. We conducted prospective analyses of the relation of experiences of racism with asthma incidence in the Black Women’s Health Study, a prospective cohort of black women in the United States followed since 1995 with mailed biennial questionnaires. Methods: Among 38,142 participants followed from 1997 to 2011, 1,068 reported incident asthma. An everyday racism score was created based on five questions asked in 1997 and 2009 about the frequency in daily life of experiences of racism (eg, poor service in stores), and a lifetime racism score was based on questions about racism on the job, in housing, and by police. We used Cox regression models to derive multivariable incidence rate ratios (IRRs) and 95% CIs for categories of each racism score in relation to incident asthma. Results: The IRRs were 1.45 (95% CI, 1.19-1.78) for the highest compared with the lowest quartile of the 1997 everyday racism score (P for trend <.0001) and 1.44 (95% CI, 1.18-1.75) for the highest compared with the lowest category of 1997 lifetime racism. Among women who reported the same levels of racism in 1997 and 2009, the IRRs for the highest categories of everyday and lifetime racism were 2.12 (95% CI, 1.55-2.91) and 1.66 (95% CI, 1.20-2.30), respectively. Conclusions: Given the high prevalence of experiences of racism and asthma in black women in the United States, a positive association between racism and asthma is of public health importance.

    Full Text Available Abeta peptide accumulation is thought to be the primary event in the pathogenesis of Alzheimer's disease (AD, with downstream neurotoxic effects including the hyperphosphorylation of tau protein. Glycogen synthase kinase-3 (GSK-3 is increasingly implicated as playing a pivotal role in this amyloid cascade. We have developed an adult-onset Drosophila model of AD, using an inducible gene expression system to express Arctic mutant Abeta42 specifically in adult neurons, to avoid developmental effects. Abeta42 accumulated with age in these flies and they displayed increased mortality together with progressive neuronal dysfunction, but in the apparent absence of neuronal loss. This fly model can thus be used to examine the role of events during adulthood and early AD aetiology. Expression of Abeta42 in adult neurons increased GSK-3 activity, and inhibition of GSK-3 (either genetically or pharmacologically by lithium treatment rescued Abeta42 toxicity. Abeta42 pathogenesis was also reduced by removal of endogenous fly tau; but, within the limits of detection of available methods, tau phosphorylation did not appear to be altered in flies expressing Abeta42. The GSK-3-mediated effects on Abeta42 toxicity appear to be at least in part mediated by tau-independent mechanisms, because the protective effect of lithium alone was greater than that of the removal of tau alone. Finally, Abeta42 levels were reduced upon GSK-3 inhibition, pointing to a direct role of GSK-3 in the regulation of Abeta42 peptide level, in the absence of APP processing. Our study points to the need both to identify the mechanisms by which GSK-3 modulates Abeta42 levels in the fly and to determine if similar mechanisms are present in mammals, and it supports the potential therapeutic use of GSK-3 inhibitors in AD.

    High body mass index (BMI) (calculated as weight (kg)/height (m)2) is associated with increased asthma risk, but uncertainty persists about the role of physical activity. We estimated the independent and joint associations of hypothetical interventions on BMI and physical activity with the risk of adult-onset asthma in 76,470 asthma-free women from the Nurses’ Health Study who were followed between 1988 and 1998. Information about asthma, BMI, physical activity, and other factors was updated ...

    Serum ferritin rises in the anemia of chronic inflammation reflecting increased iron storage and other changes mediated by inflammation. When iron deficiency coexists, the ferritin may not always decline into the subnormal range. We describe the rare interaction of iron deficiency with the extreme hyperferritinemia characteristic of adult onset Still's disease. The combination has clinical relevance and allows deductions about the presence of serum ferritin at 26,387 μg/L despite obvious iron...

    Growth hormone (GH) and insulin-like growth factor-I (IGF-I) provide trophic support during development and also appear to influence cell structure, function and replacement in the adult brain. Recent studies demonstrated effects of the GH/IGF-I axis on adult neurogenesis, but it is unclear whether the GH/IGF-I axis influences glial turnover in the normal adult brain. In the current study we used a selective model of adult-onset GH and IGF-I deficiency to evaluate the role of GH and IGF-I in ...

    Adult onset Still's disease (AOSD) is an uncommon, multisystemic, auto-inflammatory disorder, while breast augmentation is a very common cosmetic procedure. We describe a case in which these two coalesce, AOSD, manifested with pleuritis and pericarditis, developed after breast mammoplasty. The pathogenetic, missing link, behind the development of AOSD following mammoplasty, is thought to be the autoimmune (auto-inflammatory) syndrome induced by adjuvants (ASIA). We reviewed other cases of AOSD associated with breast mammoplasty published to date and the literature regarding AOSD and ASIA syndrome. The review is followed by a short debate of whether silicone implants should be explanted in similar, future cases. PMID:25604318

    We report the clinical, biochemical, and molecular genetic findings in a family with an unusual mitochondrial disease phenotype harboring a novel mtDNA tRNA glutamic acid mutation at position 14709. The proband and his sister presented with congenital myopathy and mental retardation and subsequently developed cerebellar ataxia. Other family members had either adult-onset diabetes mellitus with muscle weakness or adult-onset diabetes mellitus alone. Ragged-red and cytochrome c oxidase (COX)-negative fibers were present in muscle biopsies. Biochemical studies of muscle mitochondria showed reduced complex I and IV activities. The mtDNA mutation was heteroplasmic in blood and muscle in all matrilineal relatives analyzed. Primary myoblast, but not fibroblast, cultures containing high proportions of mutant mtDNA exhibited impaired mitochondrial translation. These observations indicate that mtDNA tRNA point mutations should be considered in the differential diagnosis of congenital myopathy. In addition they illustrate the diversity of phenotypes associated with this mutation in the same family and further highlight the association between mtDNA mutations and diabetes mellitus. 43 refs., 4 figs., 1 tab.

    Obesity is an emerging health problem in purebred dogs. Due to their crucial role in energy homeostasis control, genes encoding adipokines are considered candidate genes, and their variants may be associated with predisposition to obesity. Searching for polymorphism was carried out in three adipokine genes (TNF, RETN and IL6). The study was performed on 260 dogs, including lean (n = 109), overweight (n = 88) and obese (n = 63) dogs. The largest cohort was represented by Labrador Retrievers (n = 136). Altogether, 24 novel polymorphisms were identified: 12 in TNF (including one missense SNP), eight in RETN (including one missense SNP) and four in IL6. Distributions of five common SNPs (two in TNF, two in RETN and one in IL6) were further analyzed with regard to body condition score. Two SNPs in the non-coding parts of TNF (c.-40A>C and c.233+14G>A) were associated with obesity in Labrador dogs. The obtained results showed that the studied adipokine genes are highly polymorphic and two polymorphisms in the TNF gene may be considered as markers predisposing Labrador dogs to obesity.

    Type-1 diabetes (T1D) is a heterogeneous autoimmune disease, and there are pathogenetic differences between young- and adult-onset T1D patients. We hypothesized that the expressions of genes involved in costimulatory immune system pathways in peripheral blood are differently regulated in young- and adult-onset T1D. Study group I consisted of 80 children, adolescents, and young adults (age range 1.4-21.4 y; 31 controls and 49 T1D patients). Study group II consisted of 48 adults (age range 22.0-78.4 y; 30 controls and 18 T1D patients). The mRNA expression levels of CD86, CD28, CD25, CD226, CD40, BTLA, GITR, PDCD1, FoxP3, TGF-β, ICOS, sCTLA4, flCTLA4, and CD80 were measured in peripheral blood. Genetic polymorphisms (HLA haplotypes; rs231806, rs231775, and rs3087243 in CTLA4; rs763361 in CD226; and rs706778 in CD25) and T1D-associated autoantibodies were analyzed. In group I, there was significantly lower expression of CD226 in T1D patients than in the controls. In group II, there were significantly higher expression levels of CD86 and TGF-β in T1D patients than in the controls. In the T1D patients in group I, the upregulated CD80 expression correlated with the expression of both CTLA4 splice variants (sCTLA4 and flCTLA4). In contrast, in group II, upregulated CD86 correlated with TGF-β and CD25. In group I, the inhibitory CD80-CTLA4 pathway was activated, whereas, in group II, the activation CD86-CD28 pathway and TGF-β production were activated. These results emphasize the differences between young-onset and adult-onset T1D in the regulation of costimulatory pathways. These differences should be considered when developing novel treatments for T1D. PMID:25980680

    Full text of the publication follows: Thyroid cancer is one of the malignancies most strongly associated with ionizing radiation in humans. Epidemiology studies of atomic bomb (A-bomb) survivors have indicated that excess relative risk of papillary thyroid cancer per Gy was remarkably high in the survivors. We therefore aim to clarify mechanisms linking A-bomb radiation exposure and development of papillary thyroid cancer. Toward this end, we intend to clarify characteristics of gene alterations occurring in radiation-associated adult-onset papillary thyroid cancer from the Life Span Study cohort of A-bomb survivors. We have thus far found that with increased radiation dose, papillary thyroid cancer cases with chromosomal rearrangements (mainly RET/PTC rearrangements) significantly increased and papillary thyroid cancer cases with point mutations (mainly BRAF-V600E) significantly decreased. Papillary thyroid cancer cases with non-detected gene alterations that carried no mutations in RET, NTRK1, BRAF or RAS genes tended to increase with increased radiation dose. In addition, we found that relative frequency of these papillary thyroid cancer cases significantly decreased with time elapsed since exposure. Through analysis of papillary thyroid cancer cases with non-detected gene alterations, we recently discovered a new type of rearrangement for the first time in papillary thyroid cancer, i.e., rearranged anaplastic lymphoma kinase (ALK) gene, although identification of any partner gene(s) is needed. Specifically, rearrangement of ALK was found in 10 of 19 exposed papillary thyroid cancer cases with non-detected gene alterations but not in any of the six non-exposed papillary thyroid cancer cases. Furthermore, papillary thyroid cancer with ALK rearrangement was frequently found in the cases with high radiation dose or with short time elapsed since A-bomb exposure. These results suggest that chromosomal rearrangement, typically of RET and ALK, may play an important

Papillary thyroid cancer cases with non-detected gene alterations that carried no mutations in RET, NTRK1, BRAF or RAS genes tended to increase with increased radiation dose. In addition, we found that relative frequency of these papillary thyroid cancer cases significantly decreased with time elapsed since exposure. Through analysis of papillary thyroid cancer cases with non-detected gene alterations, we recently discovered a new type of rearrangement for the first time in papillary thyroid cancer, i.e., rearranged anaplastic lymphoma kinase (ALK) gene, although identification of any partner gene(s) is needed. Specifically, rearrangement of ALK was found in 10 of 19 exposed papillary thyroid cancer cases with non-detected gene alterations but not in any of the six non-exposed papillary thyroid cancer cases. Furthermore, papillary thyroid cancer with ALK rearrangement was frequently found in the cases with high radiation dose or with short time elapsed since A-bomb exposure. These results suggest that chromosomal rearrangement, typically of RET and ALK, may play an important

    Full Text Available Abstract Background Visceral white adipose tissue (WAT hypertrophy, adipokine production, inflammation and fibrosis are strongly associated with obesity, but the time-course of these changes in-vivo are not fully understood. Therefore, the aim of this study was to establish the time-course of changes in adipocyte morphology, adipokines and the global transcriptional landscape in visceral WAT during the development of diet-induced obesity. Results C57BL/6 J mice were fed a high-fat diet (HFD or normal diet (ND and sacrificed at 8 time-points over 24 weeks. Excessive fat accumulation was evident in visceral WAT depots (Epidydimal, Perirenal, Retroperitoneum, Mesentery after 2–4 weeks. Fibrillar collagen accumulation was evident in epidydimal adipocytes at 24 weeks. Plasma adipokines, leptin, resistin and adipsin, increased early and time-dependently, while adiponectin decreased late after 20 weeks. Only plasma leptin and adiponectin levels were associated with their respective mRNA levels in visceral WAT. Time-course microarrays revealed early and sustained activation of the immune transcriptome in epididymal and mesenteric depots. Up-regulated inflammatory genes included pro-inflammatory cytokines, chemokines (Tnf, Il1rn, Saa3, Emr1, Adam8, Itgam, Ccl2, 3, 4, 6, 7 and 9 and their upstream signalling pathway genes (multiple Toll-like receptors, Irf5 and Cd14. Early changes also occurred in fibrosis, extracellular matrix, collagen and cathepsin related-genes, but histological fibrosis was only visible in the later stages. Conclusions In diet-induced obesity, early activation of TLR-mediated inflammatory signalling cascades by CD antigen genes, leads to increased expression of pro-inflammatory cytokines and chemokines, resulting in chronic low-grade inflammation. Early changes in collagen genes may trigger the accumulation of ECM components, promoting fibrosis in the later stages of diet-induced obesity. New therapeutic approaches

    Adult-onset sporadic ataxias are a group of disorders manifested predominantly with ataxia, due to a variety of the potential causes including intoxication, immune-mediation, vitamins deifciencies, infections, neurodegeneration, and even some hereditary conditions. The clinical spectrum of these disorders is diverse, and their diagnosis remains a challenge. Compared with hereditary ataxias, most ataxias in this group respond the treatment well, that means the signiifcance of timely and correct diagnosis. The advanced biochemical, immune and imaging tools will help the perception and management on those ataxias. Different categories of adult-onset sporadic ataxia were elucidated with the highlight on their clinical features, neuro-imagingand diagnostic criteria.%成人发病的散发性共济失调症是由多种原因所致,临床表现以共济失调为主要的多种疾病。致病原因包括中毒、免疫介导性、维生素缺乏、感染性疾病、变性病以及遗传性疾患等。散发性共济失调临床谱具有明显异质性,临床正确诊断极具挑战性。但相比于遗传性共济失调症,此类疾患多数治疗效果较好,及时、正确诊断尤为重要。现代生化、免疫以及影像学技术有助于此类疾患的认识和诊治。文中综述并讨论可致成人发病的散发性共济失调的不同疾病分类,并着重其临床和神经影像学表现及诊断标准。

  8. Iron Deficiency Anemia in Adult Onset Still's Disease with a Serum Ferritin of 26,387 μg/L

    2011-01-01

    Full Text Available Serum ferritin rises in the anemia of chronic inflammation reflecting increased iron storage and other changes mediated by inflammation. When iron deficiency coexists, the ferritin may not always decline into the subnormal range. We describe the rare interaction of iron deficiency with the extreme hyperferritinemia characteristic of adult onset Still's disease. The combination has clinical relevance and allows deductions about the presence of serum ferritin at 26,387 μg/L despite obvious iron depletion. The diagnosis of iron deficiency anemia was delayed and became fully obvious when her Still's disease remitted and serum ferritin decreased to 6.5 μg/L. The coexistence of iron deficiency should be considered when evaluating a patient with anemia of chronic inflammation even when the ferritin level is elevated several hundredfold. Further insights on ferritin metabolism in Still's disease are suggested by the likelihood that the patient's massive hyperferritinemia in the acute phase of Still's disease was almost entirely of the iron-free apoferritin form.

    High-fat diet (HFD) induced obesity and concomitant development of insulin resistance (IR) and type 2 diabetes mellitus have been linked to mitochondrial dysfunction. However, it is not clear whether mitochondrial dysfunction is a direct effect of a HFD or if the mitochondrial function is reduced with increased HFD duration. We hypothesized that the function of mitochondrial oxidative and lipid metabolism functions in skeletal muscle mitochondria for HFD mice are similar or elevated relative to standard diet (SD) mice, thereby IR is neither cause nor consequence of mitochondrial dysfunction. We applied a chemical probe approach to identify functionally reactive ATPases and nucleotide-binding proteins in mitochondria isolated from skeletal muscle of C57Bl/6J mice fed HFD or SD chow for 2-, 8-, or 16-weeks; feeding time points known to induce IR. A total of 293 probe-labeled proteins were identified by mass spectrometry-based proteomics, of which 54 differed in abundance between HFD and SD mice. We found proteins associated with the TCA cycle, oxidative phosphorylation (OXPHOS), and lipid metabolism were altered in function when comparing SD to HFD fed mice at 2-weeks, however by 16-weeks HFD mice had TCA cycle, β-oxidation, and respiratory chain function at levels similar to or higher than SD mice.

    The present paper is focusing on rare diseases manifesting in late childhood or adulthood. A part of these syndromes are not of genetic origin, such as relatively or absolutely rare infections, autoimmune diseases, tumours, or diseases due to rare environmental toxic agents. In addition, even a large proportion of genetic disorders may develop in adulthood or may have adult forms as well, affecting are almost each medical specialization. Examples are storage disorders (e.g. adult form of Tay-Sachs disease, Gaucher-disease), enzyme deficiencies (e.g. ornithin-transcarbamylase deficiency of the urea cycle disorders), rare thrombophilias (e.g. homozygous factor V. Leiden mutation, antithrombin deficiency), or some rare monogenic disorders such as Huntington-chorea and many others. It is now generally accepted that at least half of the 6-8000 "rare diseases" belong either to the scope of adult-care (e.g. internal medicine, neurology), or to "age-neutral" specialities such as ophtalmology, dermatology etc.).

    S100A8/A9 has been suggested as a marker of disease activity in patients with adult-onset Still’s disease (AOSD). We evaluated the clinical significance of S100A8/A9 as a biomarker and its pathogenic role in AOSD. Blood samples were collected prospectively from 20 AOSD patients and 20 healthy controls (HCs). Furthermore, skin and lymph node biopsy specimens of AOSD patients were investigated for S100A8/A9 expression levels via immunohistochemistry. Peripheral blood mononuclear cells (PBMCs) of active AOSD patients and HCs were investigated for S100A8/A9 cell signals. S100A8/A9, interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) levels in active AOSD patients were higher than those of HCs. S100A8/A9 levels correlated positively with IL-1β, TNF-α and C-reactive protein. The inflammatory cells expressing S100A8/A9 were graded from one to three in skin and lymph node biopsies of AOSD patients. The grading for S100A8/A9 was more intense in the skin lesions with karyorrhexis, mucin deposition, and neutrophil infiltration. Like lipopolysaccharide (LPS), S100A8/A9 induced phosphorylation of p38 and c-Jun amino-terminal kinase (JNK) in PBMCs, suggesting that S100A8/A9 activates Toll-like receptor 4 signaling pathways. These findings suggest that S100A8/A9 may be involved in the inflammatory response with induction of proinflammatory cytokines and may serve as a clinicopathological marker for disease activity in AOSD.

    Glaucoma, the leading cause of irreversible blindness, appears in various forms. Mutations in CYP1B1 result in primary congenital glaucoma (PCG) by an autosomal recessive mode of inheritance while it acts as a modifier locus for primary open angle glaucoma (POAG). We investigated the molecular basis of the variable phenotypes resulting from the defects in CYP1B1 by using subclones of 23 CYP1B1 mutants reported in glaucoma patients, in a cell based system by measuring the dual activity of the enzyme to metabolize both retinol and 17β-estradiol. Most variants linked to POAG showed low steroid metabolism while null or very high retinol metabolism was observed in variants identified in PCG. We examined the translational turnover rates of mutant proteins after the addition of cycloheximide and observed that the levels of enzyme activity mostly corroborated the translational turnover rate. We performed extensive normal mode analysis and molecular-dynamics-simulations-based structural analyses and observed significant variation of fluctuation in certain segmental parts of the mutant proteins, especially at the B-C and F-G loops, which were previously shown to affect the dynamic behavior and ligand entry/exit properties of the cytochrome P450 family of proteins. Our molecular study corroborates the structural analysis, and suggests that the pathologic state of the carrier of CYP1B1 mutations is determined by the allelic state of the gene. To our knowledge, this is the first attempt to dissect biological activities of CYP1B1 for correlation with congenital and adult onset glaucomas. PMID:27243976

    Full Text Available Abstract Background To get insight into molecular mechanisms underlying insulin resistance, we compared acute in vivo effects of insulin on adipose tissue transcriptional profiles between obese insulin-resistant and lean insulin-sensitive women. Methods Subcutaneous adipose tissue biopsies were obtained before and after 3 and 6 hours of intravenously maintained euglycemic hyperinsulinemia from 9 insulin-resistant and 11 insulin-sensitive females. Gene expression was measured using Affymetrix HG U133 Plus 2 microarrays and qRT-PCR. Microarray data and pathway analyses were performed with Chipster v1.4.2 and by using in-house developed nonparametric pathway analysis software. Results The most prominent difference in gene expression of the insulin-resistant group during hyperinsulinemia was reduced transcription of nuclear genes involved in mitochondrial respiration (mitochondrial respiratory chain, GO:0001934. Inflammatory pathways with complement components (inflammatory response, GO:0006954 and cytokines (chemotaxis, GO:0042330 were strongly up-regulated in insulin-resistant as compared to insulin-sensitive subjects both before and during hyperinsulinemia. Furthermore, differences were observed in genes contributing to fatty acid, cholesterol and triglyceride metabolism (FATP2, ELOVL6, PNPLA3, SREBF1 and in genes involved in regulating lipolysis (ANGPTL4 between the insulin-resistant and -sensitive subjects especially during hyperinsulinemia. Conclusions The major finding of this study was lower expression of mitochondrial respiratory pathway and defective induction of lipid metabolism pathways by insulin in insulin-resistant subjects. Moreover, the study reveals several novel genes whose aberrant regulation is associated with the obese insulin-resistant phenotype.

    Full Text Available AMP-activated protein kinase (AMPK is suppressed in diabetes and may be due to a high ATP/AMP ratio, however the quantitation of nucleotides in vivo has been extremely difficult. Via matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI to localize renal nucleotides we found that the diabetic kidney had a significant increase in glomerular ATP/AMP ratio. Untargeted MALDI-MSI analysis revealed that a specific sphingomyelin species (SM(d18:1/16:0 accumulated in the glomeruli of diabetic and high-fat diet-fed mice compared with wild-type controls. In vitro studies in mesangial cells revealed that exogenous addition of SM(d18:1/16:0 significantly elevated ATP via increased glucose consumption and lactate production with a consequent reduction of AMPK and PGC1α. Furthermore, inhibition of sphingomyelin synthases reversed these effects. Our findings suggest that AMPK is reduced in the diabetic kidney due to an increase in the ATP/AMP ratio and that SM(d18:1/16:0 could be responsible for the enhanced ATP production via activation of the glycolytic pathway.

    Full Text Available Obesity is a major health problem and an immense economic burden on the health care systems both in the United States and the rest of the world. The prevalence of obesity in children and adults in the United States has increased dramatically over the past decade. Besides environmental factors, genetic factors are known to play an important role in the pathogenesis of obesity. Genome-wide association studies (GWAS have revealed strongly associated genomic variants associated with most common disorders; indeed there is general consensus on these findings from generally positive replication outcomes by independent groups. To date, there have been only a few GWAS-related reports for childhood obesity specifically, with studies primarily uncovering loci in the adult setting instead. It is clear that a number of loci previously reported from GWAS analyses of adult BMI and/or obesity also play a role in childhood obesity.

    Free and conjugated steroids coexist in a dynamic equilibrium due to complex biosynthetic and metabolic processes. This may have clinical significance related to various physiological conditions, including sex development involving the reproductive system. Therefore, we performed quantitative profiling of 16 serum steroids conjugated with glucuronic and sulfuric acids using liquid chromatography-mass spectrometry (LC-MS). All steroid conjugates were purified by solid-phase extraction and then separated through a 3-μm particle size C18 column (150mm×2.1mm) at a flow rate of 0.3 mL/min in the negative ionization mode. The LC-MS-based analysis was found to be linear (r(2)>0.99), and all steroid conjugates had a limit-of-quantification (LOQ) of 10ng/mL, except for cholesterol sulfate and 17β-estradiol-3,17-disulfate (20ng/mL). The extraction recoveries of all steroid conjugates ranged from 97.9% to 110.7%, while the overall precision (% CV) and accuracy (% bias) ranged from 4.8% to 10.9% and from 94.4% to 112.9% at four different concentrations, respectively. Profiling of steroid conjugates corrected by adiposity revealed decreased levels of steroid sulfates (Psteroid conjugates and for understanding the pathophysiology and relative contributions of adiposity in childhood obesity.

    The serum lipid metabolites of lean and obese mice fed normal or high-fat diets were analyzed via direct infusion nanoelectrospray-ion trap mass spectrometry followed by multivariate analysis. In addition, lipidomic biomarkers responsible for the pharmacological effects of compound K-reinforced ginsenosides (CK), thus the CK fraction, were evaluated in mice fed high-fat diets. The obese and lean groups were clearly discriminated upon principal component analysis (PCA) and partial least-squares discriminant analysis (PLS-DA) score plot, and the major metabolites contributing to such discrimination were triglycerides (TGs), cholesteryl esters (CEs), phosphatidylcholines (PCs), and lysophosphatidylcholines (LPCs). TGs with high total carbon number (>50) and low total carbon number (fat diet induced obesity in mice, respectively. When the CK fraction was fed to obese mice that consumed a high-fat diet, the levels of certain lipids including LPCs and CEs became similar to those of mice fed a normal diet. Such metabolic markers can be used to better understand obesity and related diseases induced by a hyperlipidic diet. Furthermore, changes in the levels of such metabolites can be employed to assess the risk of obesity and the therapeutic effects of obesity management. PMID:25744175

  3. IL-2 immunotherapy reveals potential for innate beta cell regeneration in the non-obese diabetic mouse model of autoimmune diabetes.

    Directory of Open Access Journals (Sweden)

    Yaiza Diaz-de-Durana

    Full Text Available Type-1 diabetes (T1D is an autoimmune disease targeting insulin-producing beta cells, resulting in dependence on exogenous insulin. To date, significant efforts have been invested to develop immune-modulatory therapies for T1D treatment. Previously, IL-2 immunotherapy was demonstrated to prevent and reverse T1D at onset in the non-obese diabetic (NOD mouse model, revealing potential as a therapy in early disease stage in humans. In the NOD model, IL-2 deficiency contributes to a loss of regulatory T cell function. This deficiency can be augmented with IL-2 or antibody bound to IL-2 (Ab/IL-2 therapy, resulting in regulatory T cell expansion and potentiation. However, an understanding of the mechanism by which reconstituted regulatory T cell function allows for reversal of diabetes after onset is not clearly understood. Here, we describe that Ab/IL-2 immunotherapy treatment, given at the time of diabetes onset in NOD mice, not only correlated with reversal of diabetes and expansion of Treg cells, but also demonstrated the ability to significantly increase beta cell proliferation. Proliferation appeared specific to Ab/IL-2 immunotherapy, as anti-CD3 therapy did not have a similar effect. Furthermore, to assess the effect of Ab/IL-2 immunotherapy well after the development of diabetes, we tested the effect of delaying treatment for 4 weeks after diabetes onset, when beta cells were virtually absent. At this late stage after diabetes onset, Ab/IL-2 treatment was not sufficient to reverse hyperglycemia. However, it did promote survival in the absence of exogenous insulin. Proliferation of beta cells could not account for this improvement as few beta cells remained. Rather, abnormal insulin and glucagon dual-expressing cells were the only insulin-expressing cells observed in islets from mice with established disease. Thus, these data suggest that in diabetic NOD mice, beta cells have an innate capacity for regeneration both early and late in disease

    Chronic and adult-onset G{sub M2} gangliosidoses are neurological disorders caused by marked deficiency of the A isoenzyme of {beta}-hexosaminidase; they occur in the Ashkenazi Jewish population, though less frequently than classic (infantile) Tay-Sachs disease. Earlier biosynthetic studies had identified a defective {alpha}-subunit that failed to associate with the {beta}-subunit. The authors have now found a guanosine to adenosine transition at the 3{prime} end of exon 7, which causes substitution of serine for glycine at position 269 of the {alpha}-subunit. An RNase protection assay was used to localize the mutation to a segment of mRNA from fibroblasts of a patient with the adult-onset disorder. That segment of mRNA (after reverse transcription) and a corresponding segment of genomic DNA were amplified by the polymerase chain reaction and sequenced by the dideoxy method. The sequence analysis, together with an assay based on the loss of a ScrFI restriction site, showed that the patient was a compound heterozygote who had inherited the 269 (Gly {yields} Ser) mutation from his father and an allelic null mutation from his mother. The 269 (Gly {yields} Ser) mutation, in compound heterozygosity with a presumed null allele, was also found in fetal fibroblasts with an association-defective phenotype and in cells from five patients with chronic G{sub M2} gangliosidosis.

    Full Text Available Environmental compounds are known to promote epigenetic transgenerational inheritance of adult onset disease in subsequent generations (F1-F3 following ancestral exposure during fetal gonadal sex determination. The current study was designed to determine if a mixture of plastic derived endocrine disruptor compounds bisphenol-A (BPA, bis(2-ethylhexylphthalate (DEHP and dibutyl phthalate (DBP at two different doses promoted epigenetic transgenerational inheritance of adult onset disease and associated DNA methylation epimutations in sperm. Gestating F0 generation females were exposed to either the "plastics" or "lower dose plastics" mixture during embryonic days 8 to 14 of gonadal sex determination and the incidence of adult onset disease was evaluated in F1 and F3 generation rats. There were significant increases in the incidence of total disease/abnormalities in F1 and F3 generation male and female animals from plastics lineages. Pubertal abnormalities, testis disease, obesity, and ovarian disease (primary ovarian insufficiency and polycystic ovaries were increased in the F3 generation animals. Kidney and prostate disease were only observed in the direct fetally exposed F1 generation plastic lineage animals. Analysis of the plastics lineage F3 generation sperm epigenome previously identified 197 differential DNA methylation regions (DMR in gene promoters, termed epimutations. A number of these transgenerational DMR form a unique direct connection gene network and have previously been shown to correlate with the pathologies identified. Observations demonstrate that a mixture of plastic derived compounds, BPA and phthalates, can promote epigenetic transgenerational inheritance of adult onset disease. The sperm DMR provide potential epigenetic biomarkers for transgenerational disease and/or ancestral environmental exposures.

    Full Text Available Being overweight or obese is a significant public health problem in the 21st century due to its scale, common existence and its cause-effect association with multiple diseases. Excessive accumulation of adipose tissue in humans is regarded as a major risk factor for development of cardiovascular and skeletal diseases. However, data from recent years have revealed that obesity is also strongly associated with increased risk of the majority of cancers in humans, including those originating from the gastrointestinal tract. During the last few year this association has been thoroughly proven and supported by several epidemiological analyses. The authors present i the current state of knowledge regarding key (pathomechanisms that link metabolism of human adipose tissue to development/progression of neoplasms (especially in the gastrointestinal tract, as well as ii the results of selected clinical studies in which the influence of obesity on risk of gastrointestinal cancer development has been addressed.

    Objective To investigate the association between prepregnancy obesity and birth outcomes using fixed effect models comparing siblings from the same mother. Methods A total of 7496 births to 3990 mothers from the National Longitudinal Survey of Youth 1979 survey are examined. Outcomes include macrosomia, gestational length, incidence of low birthweight, preterm birth, large and small for gestational age (LGA, SGA), c-section, infant doctor visits, mother's and infant's days in hospital post-partum, whether the mother breastfed, and duration of breastfeeding. Association of outcomes with maternal pre-pregnancy obesity was examined using Ordinary Least Squares (OLS) regression to compare across mothers and fixed effects to compare within families. Results In fixed effect models we find no statistically significant association between most outcomes and prepregnancy obesity with the exception of LGA, SGA, low birth weight, and preterm birth. We find that prepregnancy obesity is associated with a with lower risk of low birthweight, SGA, and preterm birth but controlling for prepregnancy obesity, increases in GWG lead to increased risk of LGA. Conclusions Contrary to previous studies, which have found that maternal obesity increases the risk of c-section, macrosomia, and LGA, while decreasing the probability of breastfeeding, our sibling comparison models reveal no such association. In fact, our results suggest a protective effect of obesity in that women who are obese prepregnancy have longer gestation lengths, and are less likely to give birth to a preterm or low birthweight infant.

    Worldwide prevalence of childhood obesity has increased greatly during the past three decades. The increasing occurrence in children of disorders such as type 2 diabetes is believed to be a consequence of this obesity epidemic. Much progress has been made in understanding of the genetics and physiology of appetite control and from these advances, elucidation of the causes of some rare obesity syndromes. However, these rare disorders have so far taught us few lessons about prevention or reversal of obesity in most children. Calorie intake and activity recommendations need reassessment and improved quantification at a population level because of sedentary lifestyles of children nowadays. For individual treatment, currently recommended calorie prescriptions might be too conservative in view of evolving insight into the so-called energy gap. Although quality of research into both prevention and treatment has improved, high-quality multicentre trials with long-term follow-up are needed. Meanwhile, prevention and treatment approaches to increase energy expenditure and decrease intake should continue. Recent data suggest that the spiralling increase in childhood obesity prevalence might be abating; increased efforts should be made on all fronts to continue this potentially exciting trend.

    The primary prevention of adult obesity requires combined efforts by stakeholders at various societal levels, based on the knowledge from multiple disciplines. The goal of the present study was, therefore, to analyze current preventive approaches and delineate implications for future prevention research and practice by integrating knowledge from genetics, law, economics, psychology, and social ethics (Figure 1). Inconclusive evidence on the etiology of obesity, a complex, multifactorial condition, likely complicates prevention, contributing to a lack of specificity regarding target groups, focus, and techniques of prevention. Given the urgency and significance of the "obesity problem" that requires immediate and effective solutions, it is recommended that the various existing and developing prevention programs are evaluated to ensure orientation at current risk factor research. Results from genetic risk factor research can be used as a rationale to increase specificity of preventive measures regarding identification of high-risk groups, timing, and goals of prevention. Further, it is important to evaluate prevention programs for systematic application of behavior modification techniques and consideration of individual risk factors and resources to ensure promotion of long-term behavior change that leads to weight maintenance and a reduction of incidence rates of obesity in adults (Figure 3). Although the primary prevention of childhood obesity may lead to a reduction of incidence rates of obesity in adults, high rates of adult-onset obesity and the related medical and psychosocial sequelae in adulthood underscore the necessity of preventive efforts for adults. Concerning the environmental basis of obesity prevention, in many countries, the institutional and legal framework of preventive approaches requires further examination in order to improve funding, coordination between multiple stakeholders, and implementation of prevention in the health-care system.

    This study examines (1) how the topics of obesity are framed and (2) how obese persons are portrayed on YouTube video clips. The analysis of 417 obesity videos revealed that a newer medium like YouTube, similar to traditional media, appeared to assign responsibility and solutions for obesity mainly to individuals and their behaviors, although there was a tendency that some video categories have started to show other causal claims or solutions. However, due to the prevailing emphasis on personal causes and solutions, numerous YouTube videos had a theme of weight-based teasing, or showed obese persons engaging in stereotypical eating behaviors. We discuss a potential impact of YouTube videos on shaping viewers' perceptions about obesity and further reinforcing stigmatization of obese persons. PMID:21809934

    Full Text Available The most significant impact of obesity on the musculoskeletal system is associated with osteoarthritis (OA, a disabling degenerative joint disorder characterized by pain, decreased mobility and negative impact on quality of life. OA pathogenesis relates to both excessive joint loading and altered biomechanical patterns together with hormonal and cytokine dysregulation. Obesity is associated with the incidence and progression of OA of both weight-bearing and non weight-bearing joints, to rate of joint replacements as well as operative complications. Weight loss in OA can impart clinically significant improvements in pain and delay progression of joint structural damage. Further work is required to determine the relative contributions of mechanical and metabolic factors in the pathogenesis of OA.

    Full Text Available Obesity has become a global issue. Previous studies in Bali reveal an increase in the proportionof obesity in adolescents. Obesity causes hypertension; hence there should also be an increase inthe prevalence of hypertension as well in Bali. Hypertension in obese adolescents could be causedby various factors, hence identification of the risks factors is crucial as a preventive approach.The aim of this study was to prove an association between obesity and hypertension in adolescents,and to look for the risk factors. We used an analitical cross sectional design conducted to 12-14years old samples. We took body weight, height, waist circumference, hip circumference, andblood pressure measurements with appropriate devices and asked for information regarding lifestyle and familial history by a questionnare filled in by the samples. The association of obeseadolescents with hypertension and their risk factors was analyzed by Chi-square and multivariatetests. A total of 225 subjects from Santo Yoseph junior high school students, west Denpasar,Bali, met the inclusion criteria. The proportion of obese subjects in this study was 25.7%. Wefound that proportion in familial history of obesity was greater in obese than non-obese subjects(70.7 % vs 41.3%. Logistic regression test revealed that obese subjects with hypertension had abody mass index (BMI > 30 with odds ratio of 7.3 (CI 95% = 1.8 to 28.8 and P = 0.005. Weconcluded that there was an association between obesity and adolescents with hypertension,and BMI > 30 could be a risk factor for obese adolescents with hypertension.

    This study was undertaken to assess the recent data on Malaysian adult body weights and associations of ethnic differences in overweight and obesity with comorbid risk factors, and to examine measures of energy intake, energy expenditure, basal metabolic rate (BMR) and physical activity changes in urban and rural populations of normal weight. Three studies were included (1) a summary of a national health morbidity survey conducted in 1996 on nearly 29 000 adults > or =20 years of age; (2) a study comparing energy intake, BMR and physical activity levels (PALs) in 409 ethnically diverse, healthy adults drawn from a population of 1165 rural and urban subjects 18-60 years of age; and (3) an examination of the prevalence of obesity and comorbid risk factors that predict coronary heart disease and type 2 diabetes in 609 rural Malaysians aged 30-65 years. Overweight and obesity were calculated using body mass index (BMI) measures and World Health Organization (WHO) criteria. Energy intake was assessed using 3-d food records, BMR and PALs were assessed with Douglas bags and activity diaries, while hypertension, hyperlipidaemia and glucose intolerance were specified using standard criteria. The National Health Morbidity Survey data revealed that in adults, 20.7% were overweight and 5.8% obese (0.3% of whom had BMI values of >40.0 kg m(-2)); the prevalence of obesity was clearly greater in women than in men. In women, obesity rates were higher in Indian and Malay women than in Chinese women, while in men the Chinese recorded the highest obesity prevalences followed by the Malay and Indians. Studies on normal healthy subjects indicated that the energy intake of Indians was significantly lower than that of other ethnic groups. In women, Malays recorded a significantly higher energy intake than the other groups. Urban male subjects consumed significantly more energy than their rural counterparts, but this was not the case in women. In both men and women, fat intakes (%) were

  20. Comprehensive Survey of miRNA-mRNA Interactions Reveals That Ccr7 and Cd247 (CD3 zeta) are Posttranscriptionally Controlled in Pancreas Infiltrating T Lymphocytes of Non-Obese Diabetic (NOD) Mice

    In autoimmune type 1 diabetes mellitus (T1D), auto-reactive clones of CD4+ and CD8+ T lymphocytes in the periphery evolve into pancreas-infiltrating T lymphocytes (PILs), which destroy insulin-producing beta-cells through inflammatory insulitis. Previously, we demonstrated that, during the development of T1D in non-obese diabetic (NOD) mice, a set of immune/inflammatory reactivity genes were differentially expressed in T lymphocytes. However, the posttranscriptional control involving miRNA interactions that occur during the evolution of thymocytes into PILs remains unknown. In this study, we postulated that miRNAs are differentially expressed during this period and that these miRNAs can interact with mRNAs involved in auto-reactivity during the progression of insulitis. To test this hypothesis, we used NOD mice to perform, for the first time, a comprehensive survey of miRNA and mRNA expression as thymocytes mature into peripheral CD3+ T lymphocytes and, subsequently, into PILs. Reconstruction of miRNA-mRNA interaction networks for target prediction revealed the participation of a large set of miRNAs that regulate mRNA targets related to apoptosis, cell adhesion, cellular regulation, cellular component organization, cellular processes, development and the immune system, among others. The interactions between miR-202-3p and the Ccr7 chemokine receptor mRNA or Cd247 (Cd3 zeta chain) mRNA found in PILs are highlighted because these interactions can contribute to a better understanding of how the lack of immune homeostasis and the emergence of autoimmunity (e.g., T1D) can be associated with the decreased activity of Ccr7 or Cd247, as previously observed in NOD mice. We demonstrate that these mRNAs are controlled at the posttranscriptional level in PILs. PMID:26606254

    Numerous classical genetic studies have proved that genes are contributory factors for obesity. Genes are directly responsible for obesity associated disorders such as Bardet-Biedl and Prader-Willi syndromes. However, both genes as well as environment are associated with obesity in the general population. Genetic epidemiological approaches, particularly genome-wide association studies, have unraveled many genes which play important roles in human obesity. Elucidation of their biological functions can be very useful for understanding pathobiology of obesity. In the near future, further exploration of obesity genetics may help to develop useful diagnostic and predictive tests for obesity treatment. PMID:27605733

    Full Text Available The use of modern molecular biology tools in deciphering the perturbed biochemistry and physiology underlying the obese state has proven invaluable. Identifying the hypothalamic leptin/melanocortin pathway as critical in many cases of monogenic obesity has permitted targeted, hypothesis-driven experiments to be performed, and has implicated new candidates as causative for previously uncharacterized clinical cases of obesity. Meanwhile, the effects of mutations in the melanocortin-4 receptor gene, for which the obese phenotype varies in the degree of severity among individuals, are now thought to be influenced by one's environmental surroundings. Molecular approaches have revealed that syndromes (Prader-Willi and Bardet-Biedl previously assumed to be controlled by a single gene are, conversely, regulated by multiple elements. Finally, the application of comprehensive profiling technologies coupled with creative statistical analyses has revealed that interactions between genetic and environmental factors are responsible for the common obesity currently challenging many Westernized societies. As such, an improved understanding of the different "types" of obesity not only permits the development of potential therapies, but also proposes novel and often unexpected directions in deciphering the dysfunctional state of obesity.

    Data on childhood obesity collected by the Centers for Disease Control and Prevention helped reveal the nation's epidemic of overweight and obese children. But more information is needed. Collecting body mass index (BMI)-the widely accepted measurement of childhood weight status-at the state and local levels can be instrumental in identifying and tracking obesity trends, designing interventions to help overweight children, and guiding broader policy solutions. Approximately thirty states have enacted or proposed BMI surveillance laws and regulations. Arkansas stands out as the state with the highest-quality surveillance data. Innovative strategies being pursued in a number of other states should be explored for broader dissemination. PMID:20194988

    Full Text Available Obesity is now recognised as a worldwide epidemic. The recent International Association for the Study of Obesity/International Obesity Taskforce (IASO/IOTF analysis estimates that approximately 1.0 billion adults are currently overweight and a further 475 million are obese. Obesity has huge psychosocial impact with obese children and adolescents facing discrimination and stigmatization in many areas of their lives leading to body dissatisfaction, low self-esteem and depression. Indeed, obesity is recognised as an important risk factor for the development of several chronic diseases such as hypertension, cancer, asthma and metabolic syndrome. Chronic low grade systemic inflammation is considered as a hallmark of obesity and may possibly explain the link between obesity and chronic disease, in particular the increased incidence, prevalence and severity of asthma in obese individuals. There is now strong evidence for infiltration of immune and inflammatory cells into adipose tissue that drives systemic inflammation and subsequent end organ damage. In addition to adipocytes, the key adipose tissue resident immune cells are macrophages and mast cells. Immunometabolism, as an emerging field of investigation, explores the pivotal role of these immune cells in translating immunological changes to metabolic effects in obesity. Abundance of free fatty acids, along with other inflammatory cytokines shift the balance of metabolic homeostasis to pro-inflammatory status by influencing the development of inflammatory cell lineage, which, further exhibits distinct functional phenotypes. There is emerging evidence for macrophage activation and functional polarization of an anti-inflammatory M2 phenotype towards a pro-inflammatory M1 phenotype of macrophages in obese adipose tissue. Similarly, studies in both obese humans and murine models reveal the pathognomic presence of an increased number of mast cells in visceral adipose tissue. These suggest a possible

  13. Obesity: Pathophysiology and Intervention

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available Obesity presents a major health hazard of the 21st century. It promotes co-morbid diseases such as heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Excessive energy intake, physical inactivity, and genetic susceptibility are main causal factors for obesity, while gene mutations, endocrine disorders, medication, or psychiatric illnesses may be underlying causes in some cases. The development and maintenance of obesity may involve central pathophysiological mechanisms such as impaired brain circuit regulation and neuroendocrine hormone dysfunction. Dieting and physical exercise offer the mainstays of obesity treatment, and anti-obesity drugs may be taken in conjunction to reduce appetite or fat absorption. Bariatric surgeries may be performed in overtly obese patients to lessen stomach volume and nutrient absorption, and induce faster satiety. This review provides a summary of literature on the pathophysiological studies of obesity and discusses relevant therapeutic strategies for managing obesity.

However, the effects of obesity on the respiratory system are often underappreciated. In this review, we will discuss the mechanical effects of obesity on lung physiology and the function of adipose tissue as an endocrine organ producing systemic inflammation and effecting central respiratory control. Obesity plays a key role in the development of obstructive sleep apnea and obesity hypoventilation syndrome. Asthma is more common and often harder to treat in the obese population, and in this study, we review the effects of obesity on airway inflammation and respiratory mechanics. We also discuss the compounding effects of obesity on chronic obstructive pulmonary disease (COPD and the paradoxical interaction of body mass index and COPD severity. Many practical challenges exist in caring for obese patients, and we highlight the complications faced by patients undergoing surgical procedures, especially given the increased use of bariatric surgery. Ultimately, a greater understanding of the effects of obesity on the respiratory disease and the provision of adequate health care resources is vital in order to care for this increasingly important patient population.Keywords: obesity, lung function, obstructive sleep apnea, obesity hypoventilation syndrome, anesthesia

  16. Zinc metabolism in genetically obese mice

    International Nuclear Information System (INIS)

    Recent reports indicate that the concentrations and total amounts of several essential trace metals in various tissues of genetically obese rodents differ markedly from lean controls. In the present studies the absorption, retention and tissue distribution of zinc was compared in obese (ob/ob) and lean (+/?) C57BL/6J mice. When administered 0.1 and 1 umole 65Zn by stomach tube and killed after 4 h, fasted 10 week old obese mice had 2.7 and 2.2 times more radioactivity in their carcasses, respectively, than age-matched lean mice. Higher levels of 65Zn were also present in the intestinal mucosa of obese mice. To eliminate possible differences in the effects of fasting and gastric emptying rates between the phenotypes, zinc absorption and retention were determined according to the method of Heth and Hoekstra. Analysis of data revealed that obese and lean mice absorbed 43 and 18% of the oral dose, respectively. Also, the rate of 65Zn excretion between 2 and 6 days post-treatment was similar for obese and lean mice. After 6 days obese mice had significantly lower levels of radioisotope in skin, muscle plus bone, spleen and testes and higher levels of 65Zn in liver, small intestine and adipose tissue compared to tissues from lean mice. These results demonstrate increased absorption, altered tissue distribution and similar excretion of zinc in ob/ob mice

    Obesity is the main nutritional problem and one of the most important health problems in developed societies. Central to the challenge of obesity prevention and management is a thoroughly understanding of its determinants. Multiple socio-cultural, socio-economic, behavioural and biological factors--often interrelated and many of them still unknown or poorly understood--can contribute to the establishment and perpetuation of obese phenotypes. Here, we address current research challenges regarding basic aspects of obesity and emerging science for its control, including brown adipose tissue thermogenesis and browning of white fat as possible therapeutic targets for obesity, the influence of the microbioma, and genetics, epigenetics, nutrigenomics and nutrigenetics of obesity. We also highlight hot topics in relation to food and lifestyle as determinants of obesity, including the brain mechanisms underlying environmental motivation to eat, the biological control of spontaneous physical activity, the possible role of concrete foods and food components, and the importance of early life nutrition and environment. Challenges regarding the connections of obesity with other alterations and pathologies are also briefly addressed, as well as social and economical challenges in relation to healthy food production and lifestyle for the prevention of obesity, and technological challenges in obesity research and management. The objective is to give a panoramic of advances accomplished and still ahead relevant to the different stakeholders engaged in understanding and combating obesity. PMID:24010755

    The prevalence of obesity in the Japanese population has been increasing dramatically in step with the Westernization of lifestyles and food ways. Our study demonstrated significant associations between obesity and a number of gastrointestinal disorders in a large sample population in Japan. We demonstrated that reflux esophagitis and hiatal hernia were strongly related to obesity (BMI > 25) in the Japanese. In particular, obesity with young male was a high risk for these diseases. On the other hand, it has been reported that obesity is also associated with Barrett's esophagus and colorectal adenoma; however, obesity was not a risk factor for these diseases in our study. The difference of ethnicity of our subjects may partly explain why we found no data to implicate obesity as a risk factor for Barrett's esophagus. Arterial sclerosis associated with advanced age and hyperglycemia was accompanied by an increased risk of colorectal adenoma. PMID:23781242

    Obesity is rapidly becoming an emerging disease in developing countries due to the increasing westernization of societies and change in the lifestyle. The etiology of obesity is said to be multifactorial, with a combination of genetic and environmental factors. Literature has been extensively reviewed to provide a broad overview of obesity. Data for this review were obtained from original articles, review articles and textbooks. Internet search engines were also employed. The years searched were from 1993 to 2008. Obesity, classified in terms of the body mass index and the waist-hip ratio, has several associated co-morbidities such as diabetes mellitus, hypertension, degenerative osteoarthritis and infertility. In Nigeria, there is limited information on obesity. A literature review on obesity is necessary to improve the knowledge about obesity in developing countries, its prevention and its management.

    The obesity epidemic, recognized by the World Health Organization in 1997, refers to the rising incidence of obesity worldwide. Lifestyle modification and pharmacotherapy are often ineffective long-term solutions; bariatric surgery remains the gold standard for long-term obesity weight loss. Despite the reported benefits, it has been estimated that only 1% of obese patients will undergo surgery. Endoscopic treatment for obesity represents a potential cost-effective, accessible, minimally invasive procedure that can function as a bridge or alternative intervention to bariatric surgery. We review the current endoscopic bariatric devices including space occupying devices, endoscopic gastroplasty, aspiration technology, post-bariatric surgery endoscopic revision, and obesity-related NOTES procedures. Given the diverse devices already FDA approved and in development, we discuss the future directions of endoscopic therapies for obesity. PMID:27115879

The present study was designed to test the hypothesis that obese LY mice possess differences in expression of ovarian genes relative to age-matched lean mice. Methods 90- and 180-day-old LY and lean black (C57BL/6J a/a mice were suppressed with GnRH antagonist (Antide®, then stimulated with 5 IU eCG. cRNA derived from RNA extracts of whole ovarian homogenates collected 36 h post-eCG were run individually on Codelink Mouse Whole Genome Bioarrays (GE Healthcare Life Sciences. Results Fifty-two genes showed ≥ 2-fold differential (p Cyp51, and steroidogenic acute regulatory protein (Star. Fewer genes showed lower expression in LY mice, e.g. angiotensinogen. In contrast, none of these genes showed differential expression in 90-day-old LY and black mice, which are of similar body weight. Interestingly, 180-day-old LY mice had a 2-fold greater expression of 11beta-hydroxysteroid dehydrogenase type 1 (Hsd11b1 and a 2-fold lesser expression of 11beta-hydroxysteroid dehydrogenase type 2 (Hsd11b2, differences not seen in 90-day-old mice. Consistent with altered Hsd11b gene expression, ovarian concentrations of corticosterone (C were elevated in aging LY mice relative to black mice, but C levels were similar in young LY and black mice. Conclusion The data suggest that reproductive dysfunction in aging obese mice is related to modified intraovarian gene expression that is directly related to acquired obesity.

  6. The sociology of obesity.

    Science.gov (United States)

    Rosengren, Annika; Lissner, Lauren

    2008-01-01

    The current obesity epidemic is largely driven by environmental factors, including nutritional transition towards refined and fatty foods with the growing production of energy-dense food at relatively low cost, increased access to motor vehicles, mechanisation of work and sedentary lifestyles. These influences in modern society are modified by individual characteristics. Ultimately, energy intake in excess of caloric expenditure causes obesity, but why this occurs in some but not all individuals is not known. Obesity is more prevalent in the lower socioeconomic classes but even so, there is a varying relation of socioeconomic status with obesity between countries at different stages of development and, even in the Western world, socioeconomic gradients with respect to obesity are both heterogeneous and in transition. Potential mechanisms for an effect of obesity on subsequent social status have been proposed, the most obvious being related to the stigmatisation experienced by the obese. Obesity seems to be causally related to mood disturbances, whereas there is no conclusive evidence that the reverse is true. When considering psychological aspects of obesity, depressive symptoms are more likely to be consequences, rather than causes of obesity. PMID:18230907

    Obesity is considered the most concerning and blatantly visible--yet most neglected--public health problem by the WHO. The steadily increasing number of overweight and obese people has reached 2.3 billion and 700 million worldwide, respectively. Obesity is a complex condition, one that presents serious health risks with respect to type 2 diabetes, ischemic heart disease, and hypertension, therefore controlling the global obesity epidemic decreases not only health problems, but also expenditure. The underlying cause of obesity is a metabolic disorder of genetic, central nervous system or endocrine etiology that manifests in increased nutritional intake and/or decreased physical activity ultimately leading to excessive lipogenesis. The natural treatment of obesity, that is often advised, is comprised of healthy lifestyle choices, namely low-calorie diet and exercise. However, the pharmaceutic treatment of obesity is just as important; having a better compliance rate, anti-obesity drugs also improve quality of life and patient-care outcome concerning accompanying diseases. In most countries only one drug is currently available against obesity: orlistat, which is a specific and irreversible lipase inhibitor. One of the reasons for the scarce number of anti-obesity drugs is the complex pathomechanism involved in obesity. Interference with the intricate biochemical processes that govern alimentation may lead to widespread adverse effects. The advances of the field however, have prompted novel drug leads. In the past few years FDA has approved new drugs for the treatment of obesity, recently liraglutide in 2014. The approval of drug combinations, such as phentermine/topiramate and bupropion/naltrexone are also noteworthy, the components of which have been previously approved, but not necessarily for obesity as main indication. Furthermore, there are many anti-obesity drug candidates currently in clinical phase trials, with promisingly modest adverse effect profiles; hence

    Obesity is increasing in the population as a whole, and especially in the obstetric population, among whom pregnancy-induced physiological changes impact on those already present due to obesity. In particular, changes in the cardiovascular and respiratory systems during pregnancy further alter the physiological effects and comorbidities of obesity. Obese pregnant women are at increased risk of diabetes, hypertensive disorders of pregnancy, ischaemic heart disease, congenital malformations, operative delivery postpartum infection and thromboembolism. Regional analgesia and anaesthesia is usually preferred but may be challenging. Obese pregnant women appear to have increased morbidity and mortality associated with caesarean delivery and general anaesthesia for caesarean delivery in particular, and more anaesthesia-related complications. This article summarises the physiological and pharmacological implications of obesity and pregnancy and describes the issues surrounding the management of these women for labour and delivery.

    Gastrointestinal (GI) motility has a crucial role in the food consumption, digestion and absorption, and also controls the appetite and satiety. In obese patients, various alterations of GI motility have been investigated. The prevalence of GERD and esophageal motor disorders in obese patients are higher than those of general population. Gastric emptying of solid food is generally accelerated and fasting gastric volume especially in distal stomach is larger in obese patients without change in accommodation. Contractile activity of small intestine in fasting period is more prominent, but orocecal transit is delayed. Autonomic dysfunction is frequently demonstrated in obese patients. These findings correspond with increased appetite and delayed satiety in obese patients, but causes or results have not been confirmed. Therapeutic interventions of these altered GI motility have been developed using botulinum toxin, gastric electrical stimulation in obese patients. Novel agents targeted for GI hormone modulation (such as ghrelin and leptin) need to be developed in the near future. PMID:16929152

    2010-04-01

    Full Text Available Obesity represents one of the most serious global health issues with approximately 310 million people presently affected. Main cause of it’s development is the increase of energy intake in regard to energy expenditure.Aim: The aim of the present study was to review the literature about the causes and treatment of obesity, as well as the anthropometrical measurements used for the assessment of obesity. The method οf this study included bibliography research from both the review and the research literature, mainly in the “pub med data base” which referred to the causes and treatment of obesity, as well as the anthropometrical measurements used for the assessment of obesity. Results: The prevalence of obesity has increased markedly, throughout the world. Although the etiology of obesity has not been fully understood yet, however it seems to be a multifactorial disease for which are responsible a great deal of psychological, environmental, genetic and behavioral factors. The most common anthropometrical measurement that is used for assessment of obesity is Body Mass Index (BMI and is calculated by the following equation: ΒΜΙ=Weight/Height2. A value of ΒΜΙ ≥ 30 kg/m2 equals obesity. Another simple test used to measure obesity is Waist to Hip Ratio, which measures abdominal adiposity. Values greater than 0,95 should be treated seriously as they normally indicate body fatness. The majority of studies show that life-style modification in conjunction with a well-balanced nutrition and regular physical exercise consist the cornerstone for the treatment and prevention of obesity.Conclusions: Obesity is a disease that can be preventable through modification of way of living. The development of proper strategy prevention capable to change attitudes, to promote nutrition and physical activity should be the primary goal of every community and government.

    Obesity, a worldwide epidemic, confers increased risk for multiple serious conditions, including cancer, and is increasingly recognized as a growing cause of preventable cancer risk. Chronic inflammation, a well-known mediator of cancer, is a central characteristic of obesity, leading to many of its complications, and obesity-induced inflammation confers additional cancer risk beyond obesity itself. Multiple mechanisms facilitate this strong association between cancer and obesity. Adipose tissue is an important endocrine organ, secreting several hormones, including leptin and adiponectin, and chemokines that can regulate tumor behavior, inflammation, and the tumor microenvironment. Excessive adipose expansion during obesity causes adipose dysfunction and inflammation to increase systemic levels of proinflammatory factors. Cells from adipose tissue, such as cancer-associated adipocytes and adipose-derived stem cells, enter the cancer microenvironment to enhance protumoral effects. Dysregulated metabolism that stems from obesity, including insulin resistance, hyperglycemia, and dyslipidemia, can further impact tumor growth and development. This review describes how adipose tissue becomes inflamed in obesity, summarizes ways these mechanisms impact cancer development, and discusses their role in four adipose-associated cancers that demonstrate elevated incidence or mortality in obesity.

    Full Text Available The markedly high prevalence of obesity contributes to the increased incidence of chronic diseases, such as diabetes, hypertension, sleep apnea, and heart disease. Because of high prevalence of obesity in almost all countries, it has been the focus of many researches throughout the world during the recent decades. Along with increasing researches, new concepts and controversies have been emerged. The existing controversies on the topic are so deep that some researches argue on absolutely philosophical questions such as “Is obesity a disease?” or “Is it correct to treat obesity?” These questions are based on a few theories and real data that explain obesity as a biological adaptation and also the final results of weight loss programs. Many people attempt to lose weight by diet therapy, physical activity and lifestyle modifications. Importantly, weight loss strategies in the long term are ineffective and may have unintended consequences including decreasing energy expenditure, complicated appetite control, eating disorders, reducing self-esteem, increasing the plasma and tissue levels of persistent organic pollutants that promote metabolic complications, and consequently, higher risk of repeated cycles of weight loss and weight regain. In this review, major paradoxes and controversies on obesity including classic obesity paradox, pre-obesity; fat-but-fit theory, and healthy obesity are explained. In addition, the relevant strategies like “Health at Every Size” that emphasize on promotion of global health behaviors rather than weight loss programs are explained.

    The prevalence of obesity in the United States has reached epidemic proportions. With more than 30 million Americans clinically obese, the younger population has also been affected. Surgical therapy should be offered to the severely obese patient who is refractory to nonsurgical therapy, as established by the 1991 NIH Consensus Conference on Gastrointestinal Surgery for Severe Obesity. Surgery is currently the most effective therapy for weight loss. It is far more effective than any other treatment modality, both in terms of the amount of weight loss and in terms of durability in maintaining weight loss.

    Full Text Available Background Adolescence is a phase of dynamic development in human life, marked by rapid physical growth, in addition to mental, emotional, and social development. Adolescent obesity has been related to metabolic disease, in addition to psychological disorders, which may lead to a negative impact on academic performances. Objective To assess academic performances in adolescents with obesity Methods A cross-sectional study was conducted in Junior High School No. 14 in Bandung from December 2010 to July 2011. Subjects were aged 12 to 14 years, and were divided into two groups: obese or good nutritional status. Statistical analysis using Fisher’s exact test was performed to assess the association of obesity and academic performances. T-test was used to compare subjects’ mean mathematics and Eenglish performances in the two groups. Results There were 240 students who met the inclusion criteria. Since there were 40 obese subjects in the first group, we randomized the remaining students to obtain 40 subjects with good nutritional status for the second group. Bbest academic performances in mathematics and Eenglish was obtained mostly by subjects in the good nutrition group (38/40 and 39/40, respectively. Statistical analysis revealed a significant association of lower performances in mathematics (mean difference -2.8; 95%CI -5 to -0.6; P=0.043 and English (mean difference -1.9; 95%CI -3.5 to -0.2; P=0.001 to obesity. We also found a significant association of better mathematics (P=0.001 and English performances (P=0.004 to the father’s occupation. Additional English lessons were not associated with higher English performances in the obese group (mean difference 0.2; 95%CI -2.9 to 3.2; P=0.885. Conclusion Obese adolescents tend to have poorer academic performances compared to those with good nutritional status. [Paediatr Indones. 2013;53:12-5.

    Social media interactions can inform public health risk perceptions. While research has examined the risk relationships between obesity and cancer, public attitudes about their associations remain largely unknown. We explored how these constructs were discussed together on two social media platforms. Publicly accessible Facebook and Twitter posts from a 2-month period in 2012 containing references to obesity ("obese/obesity," "overweight," and "fat") and cancer-related words were extracted (N = 3702 posts). Data cleaning yielded a final set of 1382 posts (Facebook: N = 291; Twitter: N = 1091). Using a mixed-methods approach, themes were inductively generated, and sentiment valence, structural elements, and epistemic stance were coded. Seven relational themes emerged: obesity is associated with cancer (n = 389), additional factors are associated with both obesity and cancer (n = 335), obesity causes cancer (n = 85), cancer causes obesity (n = 6), obesity is not linked to cancer (n = 13), co-occurrence (n = 492), and obesity is valued differently than cancer (n = 60). Fifty-nine percent of posts focused on an associative or causal link between obesity and cancer. Thirty-one percent of posts contained positive and/or negative sentiment. Facebook was more likely to contain any sentiment, but Twitter contained proportionately more negative sentiment. Concurrent qualitative analysis revealed a dominance of individual blame for overweight/obese persons and more support and empathy for cancer survivors. Our study reflects wide recognition of the evidence linking obesity to increased risk of cancer, a diverse set of factors perceived to be dually associated with both conditions and differing attribution of responsibility. We demonstrate that social media monitoring can provide an important gauge of public health risk perception. PMID:25865399

    The prevalence of obesity has increased worldwide over the past few decades. In 2013, the prevalence of obesity exceeded the 50% of the adult population in some countries from Oceania, North Africa, and Middle East. Lower but still alarmingly high prevalence was observed in North America (≈30%) and in Western Europe (≈20%). These figures are of serious concern because of the strong link between obesity and disease. In the present review, we summarize the current evidence on the relationship of obesity with cardiovascular disease (CVD), discussing how both the degree and the duration of obesity affect CVD. Although in the general population, obesity and, especially, severe obesity are consistently and strongly related with higher risk of CVD incidence and mortality, the one-size-fits-all approach should not be used with obesity. There are relevant factors largely affecting the CVD prognosis of obese individuals. In this context, we thoroughly discuss important concepts such as the fat-but-fit paradigm, the metabolically healthy but obese (MHO) phenotype and the obesity paradox in patients with CVD. About the MHO phenotype and its CVD prognosis, available data have provided mixed findings, what could be partially because of the adjustment or not for key confounders such as cardiorespiratory fitness, and to the lack of consensus on the MHO definition. In the present review, we propose a scientifically based harmonized definition of MHO, which will hopefully contribute to more comparable data in the future and a better understanding on the MHO subgroup and its CVD prognosis.

    2010-08-01

    The worldwide prevalence of obesity and its associated metabolic and cardiovascular disorders has risen dramatically within the past 2 decades. Our objective is to review the mechanisms that link obesity with altered kidney function. Current evidence suggests that excess weight gain may be responsible for 65-75% of the risk for arterial hypertension. Impaired renal pressure natriuresis, initially due to increased renal tubular sodium reabsorption, is a key factor linking obesity with hypertension. Obesity increases renal sodium reabsorption by activating the renin-angiotensin and sympathetic nervous systems, and by altering intrarenal physical forces. Adipose tissue functions as an endocrine organ, secreting hormones/cytokines (e.g., leptin) which may trigger sodium retention and hypertension. Additionally, excess visceral adipose tissue may physically compress the kidneys, increasing intrarenal pressures and tubular reabsorption. Eventually, sustained obesity via hyperinsulinemia, due to resistance to insulin, causes hyperfiltration, resulting in structural changes in the kidneys--glomerular hyperthrophy and occasionally focal segmental glomerulosclerosis. The consequences of kidney injury are continuous loss of glomerular filtration rate, further increase of arterial pressure and escalation of cardiovascular morbidity and mortality. There is a growing awareness of the renal consequences of obesity, and considerable progress is being made in understanding its pathophysiology. Weight reduction results in lowered proteinuria. Aside from low sodium diet and exercises, more widespread use of renoprotective therapy (e.g., ACE inhibitors and statins) in treatment of hypertension in obese subjects should be advocated. Renal protection should result in reducing the cardiovascular complications of obesity. PMID:20671624

    Full Text Available Obesity is a disease with severe health consequences and increased risk of mortality. The most commonly used criteria to assess the presence and the severity of obesity are body mass index, waist circumference, waist-to-height ratio and the presence of the health conditions caused or worsened by obesity. Worldwide obesity has more than doubled in the last 4 decades. Obesity is the second of the leading preventable causes of death worldwide (after smoking. Obesity has a plurifactorial pathogenesis. The central perturbation consists in the imbalance between calories intake and calories consumption (by inappropriate diet and sedentary lifestyle. Identification of all the ethiological factors is important for treatment and prophylaxis. Weight loss benefits are multiple and important: improvement in glicemic control and in plasma lipid levels, blood presure control, obstructiv sleep apneea reduction, improvement in management of daily activities and profesional performances, increase quality of life, reduction in mortality. Overweight or obese patient will complete a diagnostic and a treatment program. Treatment of obesity claims a targeted multidimensional therapy: weight and lifestyle management, diet, sustained physical activity in daily life, exercise, decrease life stressors, smoking cessation, drug therapy, bariatric surgery psichological, familial and social suport. Weight loss program must be carefully planned, adapted to the patient’s abilities and comorbidities and supervised by a nutritionist and a physiotherapist.

    In excess of 50% of adult population and nearly one third of children in Mexico have overweight and obesity. This accounts for slightly >32,671,000 million persons, excluding children; thus, total numbers are even more significant. These figures are alarming for those responsible for the economic future and well-being of Mexico. Overweight and obesity lead to higher risk of mortality as well as development of multiple diseases, mainly coronary heart disease, diabetes type 2, cancer, and stroke, which are at present the principal causes of mortality in Mexico. The World Health Organization (WHO) announced that there are throughout the world more than one billion adults with overweight, of whom 300 million have obesity. In addition to the obesity epidemic in Mexico, there is high prevalence of diabetes type 2. Coexistence of both epidemics has been denominated the twin epidemic. As many as 80% of cases of type 2 diabetes are linked with overweight or obesity, particularly abdominal obesity. The disease was once thought to be limited to adults, but obese children are now developing the illness. In Mexico, we are able to refer to at least three epidemics, because not only are obesity and type 2 diabetes advancing rapidly in the country, but also cardiovascular disease, linked with high prevalence of both hypertension and metabolic syndrome as reported by scientists based on Mexican National Health Survey 2000 data.

    The number of overweight and obese people is increasing at an alarming rate, especially in the developed and developing countries. Obesity is a major risk factor for diabetes, cardiovascular disease, and cancer, and in consequence for premature death. The development of obesity results from the interplay of both genetic and environmental factors, which include sedentary life style and abnormal eating habits. In the past few years a number of events accompanying obesity, affecting expression of genes which are not directly connected with the DNA base sequence (e.g. epigenetic changes), have been described. Epigenetic processes include DNA methylation, histone modifications such as acetylation, methylation, phosphorylation, ubiquitination, and sumoylation, as well as non-coding micro-RNA (miRNA) synthesis. In this review, the known changes in the profile of DNA methylation as a factor affecting obesity and its complications are described. PMID:25531701

This gives cause for concern because prepregnancy obesity is associated with a number of adverse pregnancy outcomes. The newly established Danish National Birth Cohort (DNBC) has a size that permits an...... investigation of the association between maternal obesity and rare, but important outcomes, for which more insight is needed, such as fetal death, subtypes of preterm birth, and neonatal mortality. The low participation rate of 30% to the DNBC may, however, raise new questions related to the validity of the...... findings, so we also carried out a study of the consequences of this selection on the estimates of relative risk.Studies of maternal obesity: Within the DNBC we examined the association between prepregnancy body mass index (BMI) and the risk of fetal death (n=54,505), subtypes of preterm birth (n=62...

  10. Paediatric asthma and obesity.

    None of the explanations proposed for the increase in paediatric asthma have been adequate. It is becoming apparent that the cause of the increase in asthma must be multi-factorial. Increasing attention has been focused on the role of lifestyle in the development of asthma. Lifestyle changes that have occurred in children are those in diet and decreased physical activity, with obesity being the product of these changes. The increase in asthma, obesity and a sedentary lifestyle have occurred together. However, a temporal relationship between asthma, obesity and decreased physical activity has not been determined in the paediatric literature. Limited data suggest that decreased physical activity could be playing a role in the aetiology of asthma independent of obesity. Furthermore, there has been substantial research on the benefits of exercise programmes for paediatric patients with asthma. Longitudinal trials monitoring physical activity, obesity and the development of asthma are needed. PMID:17098637

    The prevalence of obesity is increasing also in the elderly population. The European Euronut-Seneca study described an obesity prevalence of 12-41% in elderly women and of 8-24% in elderly men. Obesity in the elderly is related to the cardiometabolic risk, but also to degenerative joint diseases and impaired physical functions. Some discrepancies are caused by the description of a so-called obesity paradox with a more favourable prognosis for certain diseases in the presence of overweight compared to normal or reduced body weight. The so-called sarcopenic obesity is associated with the worst prognosis.Preventive and therapeutic regimens should consider the increased risk of malnutrition in elderly. The combinations of individually tailored nutritional recommendations and physical exercise is of advantage for the prognosis of comorbidities and the quality of life. PMID:26820990

    Obesity is a consequence of a complex interplay between the host genome and the prevalent obesogenic factors among the modern communities. The role of gut microbiota in the pathogenesis of the disorder was recently discovered; however, 16S-rRNA-based surveys revealed compelling but community-specific data. Considering this, despite unique diets, dietary habits and an uprising trend in obesity, the Indian counterparts are poorly studied. Here, we report a comparative analysis and quantification of dominant gut microbiota of lean, normal, obese and surgically treated obese individuals of Indian origin. Representative gut microbial diversity was assessed by sequencing fecal 16S rRNA libraries for each group (n=5) with a total of over 3000 sequences. We detected no evident trend in the distribution of the predominant bacterial phyla, Bacteroidetes and Firmicutes. At the genus level, the bacteria of genus Bacteroides were prominent among the obese individuals, which was further confirmed by qPCR ( > 0.05). In addition, a remarkably high archaeal density with elevated fecal SCFA levels was also noted in the obese group. On the contrary, the treated-obese individuals exhibited comparatively reduced Bacteroides and archaeal counts along with reduced fecal SCFAs. In conclusion, the study successfully identified a representative microbial diversity in the Indian subjects and demonstrated the prominence of certain bacterial groups in obese individuals; nevertheless, further studies are essential to understand their role in obesity.

    Full Text Available Obesity is a major risk factor for non-communicable diseases (NCDs, such as diabetes, cardiovascular diseases, and cancers. The worldwide prevalence of obesity has almost doubled between 1980 and 2008. In some regions, such as Europe, the Eastern Mediterranean and the Americas, more than 50% of women are overweight. Tonga, Nauru and the Cook Islands show the highest prevalence of obesity worldwide, above 60% in men and in women. China and the United States are the countries that experienced the largest absolute increase in the number of overweight and obese people between 1980 and 2008, followed by Brazil and Mexico. The regions with the largest increase in the prevalence of female obesity were Central Latin America, Oceania and Southern Latin America. Updated data provide evidence that the progression of the epidemic has effectively slowed for the past ten years in several countries. In low-income countries obesity is generally more prevalent among the better-off, while disadvantaged groups are increasingly affected as countries grow. Many studies have shown an overall socio-economic gradient in obesity in modern industrialized societies. Rates tend to decrease progressively with increasing socio-economic status. Children obesity rates in Spain are amongst the highest in the OECD. One in 3 children aged 13 to 14 are overweight. Overweight in infants and young children is observed in the upper middle-income countries. However, the fastest growth occurs in the group of lower middle-income countries. There is a growing body of evidence for an inverse association between SES and child obesity in developed countries. The prevalence of overweight and obesity is high in all age groups in many countries, but especially worrying in children and adolescents in developed countries and economies in transition.

  14. Framing obesity: the framing contest between industry and public health at the New Zealand inquiry into obesity.

    2011-12-01

    Drawing on submissions to the 2006-2007 New Zealand Inquiry into Obesity and Type 2 Diabetes, this article outlines how the food and marketing industries (industry) and the public health sector framed the issue of obesity. The analysis revealed that industry framed obesity as a consequence of poor lifestyle choices attributed largely to knowledge, cultural or other character deficits. Industry argued that lack of physical activity rather than increased food consumption was the dominant cause of obesity. In contrast, public health groups positioned obesity as a normal response to an obesogenic environment, characterized by the ubiquitous marketing and availability of low-cost, energy-dense/nutrient-poor foods. For public health groups, increased consumption of energy-dense/nutrient-poor foods was positioned as the dominant cause of obesity. Many public health submitters also suggested that social inequalities contributed to obesity. Industry emphasized education as the key solution to obesity, while public health groups argued for regulation of the activities of the food and marketing industries, and policies to address wider determinants of health and social inequalities. Identifying and documenting these frames, by making transparent the interests of the frame's sponsors, contributes to greater understanding of the wider policy context around obesity and provides useful information for public health advocacy.

    Obesity is an epidemic plaguing American society. The current study adds to a growing body of framing research as it examines the portrayal of obesity on television network news in two 5-year time periods, 1995-1999 and 2005-2009. Through content analysis of TV news transcripts from three networks (ABC, NBC, and CBS), this study analyzed episodic-thematic frames, issues, and sources. Results revealed the amount of obesity-related news coverage increased along with thematically framed stories. The use of politicians, affected others, supporters, and others as sources increased, but experts and those struggling with obesity remained primary sources. Changes in the proportion of issues discussed revealed significant decreases in the discussion of genetic causes and personal stories. Results reflect the societal impact of obesity and indicate the ways in which obesity is perceived by the public through network news. Findings provide insight for media advocacy opportunities and contribute to research on framing and obesity. PMID:22236324

    Asthma and obesity have a considerable impact on public health and their prevalence has increased in recent years. Numerous studies have linked both disorders. Most prospective studies show that obesity is a risk factor for asthma and have found a positive correlation between baseline body mass index (BMI) and the subsequent development of asthma, although these results are not conclusive when studying the association between airway hyperresponsiveness with BMI. Furthermore, several studies suggest that whereas weight gain increases the risk of asthma, weight loss improves the course of the illness. Different factors could explain this association. Obesity is capable of reducing pulmonary compliance, lung volumes and the diameter of peripheral respiratory airways as well as affecting the volume of blood in the lungs and the ventilation-perfusion relationship. Furthermore, the increase in the normal functioning of adipose tissue in obese subjects leads to a systemic proinflammatory state, which produces a rise in the serum concentrations of several cytokines, the soluble fractions of their receptors and chemokines. Many of these mediators are synthesized and secreted by cells from adipose tissue and receive the generic name of adipokines, including IL-6, IL-10, eotaxin, TNF-α, TGF- 1, PCR, leptin y adiponectin. Finally, specific regions of the human genome which are related to both asthma and obesity have been identified. Most studies point out that obesity is capable of increasing the prevalence and incidence of asthma, although this effect appears to be modest. The treatment of obese asthmatics must include a weight control program. PMID:22566313

    Full Text Available Obesity; a state of being 20% over one’s normal weight due to excessive fat; that is, it is defined as the accumulation of too much fat in the body. The rate of obesity in the world has elevated. In the last two decades, it is considered that there have been increases in the rates of the obesity with changes in the socio-economic state and nutritional habits in Turkey as well as in modern western countries. The increase of the obesity is a matter of concern but the aspect which is much more matter of concern is in the increase of obesity in women at the reproductive age or gradually increasing rate of being overweight. If the pregnant woman is obese, most of the physiological changes occurring during pregnancy may be various. During their childbearing years, obese women are at an increased risk for pregnancy-induced hypertension, gestational diabetes, labour induction, caesareans births, and failed vaginal birth following to caesarean. Nurses should have the knowledge to adapt the care they provide according to this knowledge and encourage the pregnant women to acquire behaviours which will improve their health.

  19. Obesity and economic environments.

    Sturm, Roland; An, Ruopeng

    2014-01-01

    This review summarizes current understanding of economic factors during the obesity epidemic and dispels some widely held, but incorrect, beliefs. Rising obesity rates coincided with increases in leisure time (rather than increased work hours), increased fruit and vegetable availability (rather than a decline in healthier foods), and increased exercise uptake. As a share of disposable income, Americans now have the cheapest food available in history, which fueled the obesity epidemic. Weight gain was surprisingly similar across sociodemographic groups or geographic areas, rather than specific to some groups (at every point in time; however, there are clear disparities). It suggests that if one wants to understand the role of the environment in the obesity epidemic, one needs to understand changes over time affecting all groups, not differences between subgroups at a given time. Although economic and technological changes in the environment drove the obesity epidemic, the evidence for effective economic policies to prevent obesity remains limited. Taxes on foods with low nutritional value could nudge behavior toward healthier diets, as could subsidies/discounts for healthier foods. However, even a large price change for healthy foods could close only part of the gap between dietary guidelines and actual food consumption. Political support has been lacking for even moderate price interventions in the United States and this may continue until the role of environmental factors is accepted more widely. As opinion leaders, clinicians play an important role in shaping the understanding of the causes of obesity. PMID:24853237

    Successful treatment of obesity requires a multidisciplinary approach including diet, exercise and behavioral modification. As lifestyle changes are not sufficient for some patients, pharmacologic therapies should be considered as adjuncts to lifestyle interventions. In this article, we review clinical indications, mechanisms of action, dosing/administration, side effects, drug interactions and contraindications for the six most widely prescribed obesity medications. We also summarize the efficacy data from phase 3 trials which led to drug approval. As multiple agents are sometimes required for clinically significant weight loss, the future of obesity medicine will likely involve combinations of agents in addition to behavioral counseling.

    Endocrine diseases (hypothyroidism, growth hormone deficiency, hypercortisolism) are exceptional in obese children and are searched only in case of short stature. It is not necessary to test systematically glucose tolerance (fasting glucose; oral glucose tolerance test) and lipids in order to look for obesity related comorbidities. Decreased caloric intake is the main goal for the treatment. Ways to succeed need to be adapted to each child with pragmatism and without dogmatism. Goals for treatment are reasonable (stabilization of weight excess). Weight loss surgery in obese children may be discussed in some cases with multidisciplinary expert team (doctors, surgeons, psychologist...) and close collaboration between adults teams and paediatricians.

    Nowadays, childhood obesity is one of the biggest health emergencies in the developed countries. Obesity leads to multiple metabolic alterations which increase the risk of developing diabetes and cardiovascular diseases. Thyroid function has been often described as altered in obese children, however, it is not clear whether the altered thyroid function is the cause or the consequence of fat excess. On the other hand, thyroid structure seems also to be affected. Nevertheless, both functional and structural alterations seem to improve after weight loss and therefore no treatment is needed.

    Full Text Available Type 2 diabetes mellitus is characterized by hyperglycemia, insulin resistance, and relative impairment in insulin secretion and its possible long term complications. Its pathogenesis is poorly understood, but both genetic and environmental factors, such as obesity and aging, play a key role. "Diabesity" is a new term which refers to diabetes occurring in the context of obesity. In this article, we will discuss the epidemiology and impact of diabetes and obesity and will also outline the components of the metabolic syndrome and the studies that demonstrate that screening and prevention are possible in an attempt to control this epidemic.

    2012-05-01

    Despite the availability of national evidenced-based guidelines related to pediatric obesity screening and prevention, multiple studies have shown that primary care physicians find it difficult to adhere to them or are unfamiliar with them altogether. This article presents physicians' perspectives on the use of electronic decision support tools, an alert and Smart Set, to accelerate the adoption of obesity-related recommendations into their practice. The authors interviewed providers using a test encounter walk-through technique that revealed a number of barriers to using electronic decision supports for obesity care in primary care settings. Providers' suggestions for improving their use of obesity-related decision supports are presented. Careful consideration must be given to both the development of electronic decision support tools and a multilayered educational outreach strategy if providers are going to be persuaded to use such supports to help them implement pediatric obesity prevention and management best practices.

    Full Text Available The increasing prevalence of paediatric obesity and related metabolic complications has been mainly associated with lower aerobic fitness while less is known regarding potential musculoskeletal impairments. The purpose of the present systematic review was to report the evidence regarding muscular fitness in children and adolescents with obesity. A systematic article search was conducted between November 2014 and June 2015 using MEDLINE, EMBASE, CINAHL psycINFO, SPORTDiscus and SocINDEX. Articles published in English and reporting results on muscle strength and muscular fitness in children and adolescents aged 6 to 18 years were eligible. Of 548 identified titles, 36 studies were included for analyses. While laboratory-based studies described higher absolute muscular fitness in youth with obesity compared with their lean peers, these differences are negated when corrected for body weight and lean mass, then supporting field-based investigations. All interventional studies reviewed led to improved muscular fitness in youth with obesity. Children and adolescents with obesity display impaired muscular fitness compared to healthy-weight peers, which seems mainly due to factors such as excessive body weight and increased inertia of the body. Our analysis also points out the lack of information regarding the role of age, maturation or sex in the current literature and reveals that routinely used field tests analysing overall daily muscular fitness in children with obesity provide satisfactory results when compared to laboratory-based data.

    The prevalence of overweight and obesity varies significantly across ethnic groups and among aboriginal people in Canada and appears to be increasing overall in children and youth, which will have significant health consequences in the future. Individual health behaviours, genetic predisposition, and community-level factors all contribute to the high burden of overweight and obesity across communities in Canada. Preliminary studies indicate that individuals who live in neighbourhoods in Canada with increased walkability, fewer fast food outlets, and higher socioeconomic status have lower rates of overweight/obesity when compared with other neighbourhoods. However, more research is required to understand the impact of community level factors on overweight/obesity trends in Canadian ethnic groups, including children and youth, and aboriginal people.

    We adopted a transcriptome-wide microarray analysis approach to determine the extent to which vascular gene expression is altered as a result of juvenile obesity and identify obesity-responsive mRNAs. We examined transcriptional profiles in the left anterior descending coronary artery (LAD), perivascular fat adjacent to the LAD, and descending thoracic aorta between obese (n = 5) and lean (n = 6) juvenile Ossabaw pigs (age = 22 wk). Obesity was experimentally induced by feeding the animals a high-fat/high-fructose corn syrup/high-cholesterol diet for 16 wk. We found that expression of 189 vascular cell genes in the LAD and expression of 165 genes in the thoracic aorta were altered with juvenile obesity (false discovery rate ≤ 10%) with an overlap of only 28 genes between both arteries. Notably, a number of genes found to be markedly upregulated in the LAD of obese pigs are implicated in atherosclerosis, including ACP5, LYZ, CXCL14, APOE, PLA2G7, LGALS3, SPP1, ITGB2, CYBB, and P2RY12. Furthermore, pathway analysis revealed the induction of proinflammatory and pro-oxidant pathways with obesity primarily in the LAD. Gene expression in the LAD perivascular fat was minimally altered with juvenile obesity. Together, we provide new evidence that obesity produces artery-specific changes in pretranslational regulation with a clear upregulation of proatherogenic genes in the LAD. Our data may offer potential viable drug targets and mechanistic insights regarding the molecular precursors involved in the origins of overnutrition and obesity-associated vascular disease. In particular, our results suggest that the oxidized LDL/LOX-1/NF-κB signaling axis may be involved in the early initiation of a juvenile obesity-induced proatherogenic coronary artery phenotype.

    2016-07-01

    This paper provides an up-to-date review of obesity and lower limb osteoarthritis (OA). OA is a major global cause of disability, with the knee being the most frequently affected joint. There is a proven association between obesity and knee OA, and obesity is suggested to be the main modifiable risk factor. Obese patients (Body Mass Index, BMI, over 30kg/m(2)) are more likely to require total knee arthroplasty (TKA). The global prevalence of obesity has doubled since 1980; by 2025, 47% of UK men and 36% of women are forecast to be obese. This rising global burden is a key factor in the growing rise in the use of TKA. It is therefore important to appreciate the outcomes of surgery in patients with end-stage OA and a high BMI. This review found that while OA is felt to contribute to weight gain, it is unclear whether TKA facilitates weight reduction. Surgery in obese patients is more technically challenging. This is reflected in the evidence, which suggests higher rates of short- to medium-term complications following TKA, including wound infection and medical complications, resulting in longer hospital stay, and potentially higher rates of malalignment, dislocation, and early revision. However, despite slower initial recovery and possibly lower functional scores and implant survival in the longer term, obese patients can still benefit from TKA in terms of improved function, quality of life and satisfaction. In conclusion, despite higher risks and more uncertain outcomes of surgery, higher BMI in itself should not be a contraindication to TKA; instead, each patient's individual circumstances should be considered.

    2014-06-01

    Obesity was probably rare in ancient times, with the current increase starting in the Industrial Revolution of the eighteenth century, and becoming much more widespread from about 1950, so concurrent with the increased consumption of carbohydrates from cereals in the Green Revolution. However, dietary components such as oligosaccharides from plants including cereals may improve health following fermentation to short-chain carboxylic acids in the intestine by bacteria which constitute of the microbiome. Such non-digestible and fermentable components of diet, called prebiotics, have been part of the human diet since at least Palaeolithic times, and include components of the cereals domesticated in the Neolithic Revolution. If consumption of these cereals has now increased, why is obesity increasing? One reason could be lowered prebiotic intake combined with increased intake of simple sugars, thus changing the bacteria in the microbiome. Processing of food has played an important role in this change of diet composition. Since obesity is a low-grade inflammation, changing the microbiome by increased consumption of simple carbohydrates and saturated fats may lead to obesity via increased systemic inflammation. Conversely, there is now reasonable evidence that increased dietary prebiotic intake decreases inflammation, improves glucose metabolism and decreases obesity. Would widespread increases in prebiotics in the modern diet, so mimicking Palaeolithic or Neolithic nutrition, decrease the incidence and morbidity of obesity in our communities? PMID:24844456

While several diet and exercise programs are available for weight loss and prevention of weight regain, progress is often slow and disappointing. Recently, natural bioactive phytochemicals present in foods have been discovered for their potential health benefit effects on the prevention of chronic disorders such as cancer, cardiovascular disease, inflammatory and metabolic diseases including obesity.Polyphenols are a class of naturally-occurring phytochemicals, of which some such as catechins, anthocynines, resveratrol and curcumin have been shown to modulate physiological and molecular pathways that are involved in energy metabolism, adiposity, and obesity. The potential in vivo, beneficial effects of these polyphenols on adiposity and obesity as complementary agents in the up-regulation of energy expenditure have emerged by investigating these compounds in cell cultures, animal models of obesity and in some human clinical and epidemiological studies. In this brief review, the efficacy of the above-named polyphenols and their potential efficacy to modulate obesity and some associated disorders are discussed.

    Obesity is an important disease with a growing incidence. Because obesity is related to several other diseases, and decreases life span, it is important to identify the population at risk. Several risk factors for obesity have been described in the literature. A higher incidence of obesity in certain breeds is often suggested. The aim of this study was to determine whether obesity occurs more often in certain breeds. The second aim was to relate the increased prevalence of obesity in certain breeds to the official standards of that breed. To this end, we investigated 1379 dogs of 128 different breeds by determining their body condition score (BCS). Overall, 18.6% of the show dogs had a BCS >5, and 1.1% of the show dogs had a BCS>7. There were significant differences between breeds, which could be correlated to the breed standards. It warrants firm discussions with breeders and judges in order to come to different interpretations of the standards to prevent overweight conditions from being the standard of beauty. PMID:22882163

  5. Psoriasis and Obesity

    2012-03-01

    Full Text Available In recent years, it has been thought that a strong association exists between metabolic syndrome, specifically obesity, and psoriasis. Obesity is a multifactorial disease affected by both genetic and environmental factors. Adipokines (e.g. leptin secreted by the adipose tissue are believed to play a role in the pathogenesis of psoriasis. The main role of leptin is to adjust metabolism by controlling appetite. Serum leptin levels in patients with severe and moderate psoriasis were found to be higher than in normal control groups. In many similar studies, leptin secretion has been found to stimulate keratinocyte proliferation, which is one of the characteristics of psoriasis. Although many studies showed increased prevalence of obesity in psoriasis patients, few others reported development of obesity in psoriasis patients. Additionally, obesity was found to affect treatment responses not only in classical systemic/topical treatment approaches in psoriasis, but also in newer biological treatments. Overall, increasing epidemiological evidence suggests strong association between obesity and psoriasis, increase in serum leptin levels is thought to have a major role, and weight loss may have significant impact on response to treatment.

    Obesity used to be among the more neglected public health problems, but has unfolded as a growing medical and socioeconomic burden of epidemic proportions. Morbid obesity is linked to traditional cardiovascular risk factors like, hypertension, hyperlipidemia and diabetes, and suspected to incur increased morbidity and mortality in the Western and even third world populations. This patient cohort is also at greater risk to develop coronary artery disease. Recent population-based registries revealed that 43% and 24% of all cases of coronary revascularization were carried out in overweight and obese patients, respectively. However, despite evidence of a positive correlation between obesity and increased cardiovascular morbidity, some authors have described a better clinical outcome in overweight and obese patients, a phenomenon they coined "obesity paradoxon". Thus, there is an ongoing debate in light of conflicting data and the possibility of confounding bias causing misconception and challenging the "obesity paradox". In this review article we present the current evidence and throughly discuss the validity of the "obesity paradoxon" in a variety of clinical settings.

    Previous literature reports that obese persons are discriminated in the workplace. Evidence suggests that obese people are perceived as having less leadership potential, and in comparison to normal weight peers, are expected to be less successful. This study examined whether obese people are discriminated against when applying for employment. Three hypotheses were offered in line with previous research: (1) obese people are less likely to be assessed positively on personnel suitability than normal weight people; (2) obese people in active employment are more likely to be discriminated against than people in non-active employment; and (3) obese women are more likely to be discriminated against than obese men. 181 Participants were sampled from sedentary, standing, manual and heavy manual occupations. Participants rated hypothetical candidates on their suitability for employment. Employees also completed measures of implicit and explicit attitudes toward obesity. MANOVA was conducted to examine if obese candidates were discriminated against during the recruitment procedure. Results demonstrated that participants rated obese candidates as less suitable compared with normal weight candidates and when the weight status of the candidate was not revealed for work across the four workplace groups. Participant gender and weight status also impacted perceptions of candidates’ suitability for work and discrimination toward obese candidates was higher in participants from more physically demanding occupations. The study findings contribute to evidence that obese people are discriminated against in the hiring process and support calls for policy development. PMID:27199869

    2001-10-01

    Although obesity is an easy diagnosis to make, its etiologies, pathophysiology, and symptomatology are extraordinarily complex. Progress in surgical technique and anesthesiological management has substantially improved the safety of performing operations on the severely obese in the last 20 years. These improvements have occurred more or less empirically, without a full understanding of etiology or pathophysiology, although this has advanced concomitantly with improvements in practice. This review has attempted to provide a framework to facilitate progress in the neglected areas of patient selection and choice of operation, in an effort to improve long-term outcome. Despite the disparate etiologies of obesity and its diverse comorbidities and complications, there are unifying interdependent pathogenetic mechanisms of great relevance to the practice of antiobesity surgery. The rate of eating, whether driven by HPA dysfunction, ambient stress, or related hereditary susceptibility factors including the increased energy demands of an expanded body fat mass, participates in a cycle that results in disordered satiety (see Fig. 3). This leads to substrate overload, causing extensive metabolic abnormalities such as atherogenesis, insulin resistance, thrombogenesis, and carcinogenesis. This interpretation of the pathophysiology of obesity ironically accords with the original meaning of the word obesity: "to overeat." The ultimate solution to the problem of obesity--preventing it--will not be forthcoming until the food industry is forced to lower production and change its marketing strategies, as the liquor and tobacco industries in the United States were compelled to do. This cannot occur until the large and fast-growing populations of industrialized nations become educated in the personal implications of the energy principle. Regardless of whether school curricula are modified to prioritize health education, the larger problems of cultural and economic change remain for

    Obesity has been described by the WHO as a global epidemic. Obesity is defined as a body mass index (BMI) > or = 30 kg/m2 and it is estimated that almost a quarter of the population of England are obese. Lighten Up was a randomised controlled trial that studied 740 obese or overweight men and women identified from GP records in a primary care trust in Birmingham. The study compared a range of commercial or primary care led weight reduction programmes with minimal intervention control for weight loss in obesity. The commercial weight management programmes were more effective and cheaper than the primary care based services studied. The authors calculated that patients lost an average of 1.3 kg/m2 with the most effective intervention which if maintained gives a crude cost per life year saved of 77 pound sterling. This would indicate that providing commercial weight loss programmes as an NHS funded service is a potentially cost-effective intervention. PMID:22272525

  20. Mood, food, and obesity.

    Science.gov (United States)

    Singh, Minati

    2014-01-01

    Food is a potent natural reward and food intake is a complex process. Reward and gratification associated with food consumption leads to dopamine (DA) production, which in turn activates reward and pleasure centers in the brain. An individual will repeatedly eat a particular food to experience this positive feeling of gratification. This type of repetitive behavior of food intake leads to the activation of brain reward pathways that eventually overrides other signals of satiety and hunger. Thus, a gratification habit through a favorable food leads to overeating and morbid obesity. Overeating and obesity stems from many biological factors engaging both central and peripheral systems in a bi-directional manner involving mood and emotions. Emotional eating and altered mood can also lead to altered food choice and intake leading to overeating and obesity. Research findings from human and animal studies support a two-way link between three concepts, mood, food, and obesity. The focus of this article is to provide an overview of complex nature of food intake where various biological factors link mood, food intake, and brain signaling that engages both peripheral and central nervous system signaling pathways in a bi-directional manner in obesity.

    Débora Bicudo Faria-Schützer

    Full Text Available As a result of the growth of the obese population, the number of obese women of fertile age has increased in the last few years. Obesity in pregnancy is related to greater levels of anxiety, depression and physical harm. However, pregnancy is an opportune moment for the intervention of health care professionals to address obesity. The objective of this study was to describe how obese pregnant women emotionally experience success in adequate weight control.Using a qualitative design that seeks to understand content in the field of health, the sample of subjects was deliberated, with thirteen obese pregnant women selected to participate in an individual interview. Data was analysed by inductive content analysis and includes complete transcription of the interviews, re-readings using suspended attention, categorization in discussion topics and the qualitative and inductive analysis of the content. The analysis revealed four categories, three of which show the trajectory of body care that obese women experience during pregnancy: 1 The obese pregnant woman starts to think about her body;2 The challenge of the diet for the obese pregnant woman; 3 The relation of the obese pregnant woman with the team of antenatal professionals. The fourth category reveals the origin of the motivation for the change: 4 The potentializing factors for change: the motivation of the obese woman while pregnant.During pregnancy, obese women are more in touch with themselves and with their emotional conflicts. Through the transformations of their bodies, women can start a more refined self-care process and experience of the body-mind unit. The fear for their own and their baby's life, due to the risks posed by obesity, appears to be a great potentializing factor for change. The relationship with the professionals of the health care team plays an important role in the motivational support of the obese pregnant woman.

    Full Text Available Obesity is becoming a major medical concern in several parts of the world, with huge economic impacts on health- care systems, resulting mainly from increased cardiovascular risks. At the same time, obesity leads to a number of sleep-disordered breathing patterns like obstructive sleep apnea and obesity hypoventilation syndrome (OHS, leading to increased morbidity and mortality with reduced quality of life. OHS is distinct from other sleep- related breathing disorders although overlap may exist. OHS patients may have obstructive sleep apnea/hypopnea with hypercapnia and sleep hypoventilation, or an isolated sleep hypoventilation. Despite its major impact on health, this disorder is under-recognized and under-diagnosed. Available management options include aggressive weight reduction, oxygen therapy and using positive airway pressure techniques. In this review, we will go over the epidemiology, pathophysiology, presentation and diagnosis and management of OHS.

    Obesity represents nowadays a significant health problem, leading to multiple efforts in order to identify its causal factors and the prophylactic and therapeutic approaches for its attention. Dairy intake is among the dietary factors that have been studied, and they frequently, but not consistently nor conclusively, have shown to be protective factors for the development of overweight, obesity and their comorbidities. Current literature addresses the reason underlying the association between dairy intake and obesity from two explanatory lines: the contribution of these products to total energy intake and the influence of some of their nutritional components -mainly calcium, protein and fat- on the underlying processes for the development of this condition. The objective of this article is to review the current knowledge on these topics. PMID:27603887

    Full Text Available Background: The obesity epidemic, which is among the most common nutritional disorders, is rising rapidly worldwide. It leads to several health problems such as metabolic disorders, stroke, and even cancer. Efforts to control obesity with exercise and diet have a limited value in obese patients and different approaches to do this have been tried. In this paper, we share our experience with bioenteric intragastric balloon (BIB in treating obesity: Its safety, tolerability, and its efficacy in weight reduction. Materials and Methods: From January 2009 to September 2012, a total of 190 gastric balloons was inserted on patients at the endoscopy unit in King Fahd Hospital of the University, Al-Khobar. This is an evaluation of the first 100 patients. All the patients had a body mass index of over 30 kg/m 2 and were within the age range of 17-55 with a mean age of 32 years. After consent, preballoon investigation tests and anesthesia evaluation, BIB was inserted under monitored anesthesia care sedation in the endoscopy suite. The balloon was filled with 500-700 mls of stained saline. All patients′ were given an analgesic and antiemetic for a week and antisecretory proton pump inhibitor′s for 6 months. Diet and the importance of the exercise were part of the preballoon insertion phase and protocol. The balloon was removed after 6-12 months. Results: The weight loss response to BIB in the 100 patients are classified into four groups: In the uncooperative, noncompliant patients - the maximum weight loss was 7 kg, while in the most compliant patients the weight loss reached up to 39 kg. In addition, there was significant improvement into diabetes mellitus, hypertension, dyslipidemia, and fatty liveras. Its safety and tolerability were extremely acceptable. Conclusion: Our data indicates that in well-selected patients, BIB is an effective device, which with minimum complications helps to achieve body weight loss and resolve many obesity related

    Obesity is a multifactorial disorder involving an abnormal or excessive amount of body fat. Obese people have a very high probability of developing metabolic syndrome, a condition in which cholesterol, lipid, and glucose levels rise, causing diabetes and heart disease. From the point of view of energy balance, the main contributors to obesity are excessive energy intake, inadequate energy expenditure and metabolic malfunctions. For this reason, health organisations are working to implement policies and plans to promote healthy eating and active living. However, these measures have not yet proven sufficient to combat this worldwide epidemic; therefore, drugs and bioactive compounds are being investigated to complement the existing strategies. In the present review, we discuss the available data regarding the modulation of obesity by proanthocyanidin rich extracts. Because studies with human subjects are very scarce, we focus on studies using laboratory animals. The results of in vitro studies are included because, although they cannot be directly extrapolated to the biological effects of proanthocyanidin, they can reveal some mechanisms of action.

    Full Text Available Pediatric obesity is a major health problem and has reached epidemiological proportions today. The present paper reviews major psychological issues in pediatric obesity from a developmental perspective. Research and literature has shown that a number of developmental, family, maternal and child factors are responsible in the genesis of pediatric obesity. Family food habits, early developmental lifestyle of the child, parenting, early family relationships and harmony all contribute towards the growth and development of a child. The present review focuses on the role of developmental psychological factors in the pathogenesis of pediatric obesity and highlights the developmental factors that must be kept in mind when evaluating a case of pediatric obesity.

    The pharmacological treatment of obesity should be considered when cannot be achieved a 10% weight loss with diet therapy and physical activity. The drugs effective in obesity treatment may act by different mechanisms such as reduction in food intake, inhibition of fat absorption, increase of thermogenesis and stimulation of adipocyte apoptosis. At present, we only have two marketed drugs for obesity treatment. Sibutramine is an inhibitor of norepinephrine, dopamine and serotonina reuptake which inhibits food intake and increases thermogenesis. Sibutramine administration for a year can induce a weight loss of 4-7%. Its main side effects are hypertension, headache, insomnia and constipation. Orlistat is an inhibitor of pancreatic lipase which is able to block the absorption of 30% of ingested fat. Its administration induces weight loss and reduction of ulterior weight regain. Also, this drug improves hypertension dyslipdaemia and helps to prevent diabetes in 52% of cases when administered over four years. The increase in frequency of stools and interference with vitamin absorption are its main side effects. Glucagon-like peptide 1, which increases insulin sensitivity and satiety, adiponectin and PPAR-gamma agonists which reduce insulin resistance and modulates adipocyte generation are the basis for future therapeutic approaches of obesity. Phosphatase inhibitors induce PPAR-gamma phosphorylation and UCP-1 expression leading to an increase in thermogenesis and reduction in appetite. PMID:15382615

The main reasons of obesity are excessive and unbalanced diet and lack of physical activity. Obesity and santral obesity leads to many diseases. Body mass index (weight (kg/lenght (m2 has been used extensively to define categories of body weight. All healthy adults aged 18-65 yr need moderate-intensity aerobic physical activity for a minimum of 30 min on five days each week or vigorous-intensity aerobic activitiy for a minimum of 20 min on three days each week. Also combination of these activities can be performed. It is recommended that muscle strengthening and stretching activities are performed for a minimum of two days each week. Activities of daily living that tend to be light intensity should be added. There are many benefits of regular physical activity and aerobic exercise tranning that are associated with a decrease in cardiovascular mortality. Some risks of the exercises may also be taken into account.

    2016-01-01

    Based on a public health model of obesity, this study set out to examine whether a news article reporting the obesity issue in a societal versus individual frame would increase perceptions of societal responsibilities for the obesity problem and motivate responsibility-taking behaviors. Responsibility-taking behaviors were examined at 3 levels: personal, interpersonal, and societal. Data from a Web-based experiment revealed significant framing effects on behaviors via causal and treatment responsibility attributions. The societal frame increased societal causal and treatment attribution, which led to greater likelihoods of interpersonal and social responsibility-taking behaviors as well as personal behaviors. Our findings suggest that news framing can be an effective venue for raising awareness of obesity as a societal issue and mobilizing collective efforts. PMID:26375052

    The onset of psychiatric symptoms and disorders is relatively common in childhood, occurring among youths across the weight spectrum. However, available research suggests that certain psychiatric comorbidities are more prevalent in obese children and adolescents than in healthy weight youths. First, we review research on disordered eating, including evidence to suggest that loss of control eating is associated with weight gain and obesity in youths, as well as poor outcome in family-based treatment of paediatric obesity. Second, we highlight evidence on the relationship between depression and obesity, especially in girls. Third, we present data on attention deficit hyperactivity disorder (ADHD), particularly the symptoms of impulsivity and inattention, and childhood obesity. We also consider that some medical conditions and psychotropic medications contribute to weight gain and obesity in children and adolescents. Throughout the review, we emphasize that psychiatric comorbidity may be a cause or consequence of childhood obesity, or they may share common aetiological factors. PMID:22724645

    Full Text Available Introduction: Obesity is strongly associated with coronary heart disease and it is known as an independent risk factor. So, the aim of this study was to investigate the effects of phase II comprehensive cardiac rehabilitation program on obesity indexes, functional capacity, lipid profiles, and fasting blood sugar in obese and non-obese female patients with coronary heart disease and to compare changes in these groups. Materials and Methods: Two hundred and five women with coronary heart disease participated in our study. At the beginning of study, body mass index, functional capacity, and lipid profiles and fasting blood sugar were evaluated; then, these patients were divided into two groups, patients who had BMI≥30 were known as obese and who had BMI<30 were known as non-obese patients. All of them completed the period of cardiac rehabilitation program, and 2 months later, all risk factors were examined for the second time in each group. Data were analyzed with SPSS software version 15. For comparing the mean of outcomes, independent t-tests and paired t-tests were used. Results: Data revealed that unless in weight (P=0.00 and functional capacity (P=0.001, there were no significant differences in obese and non-obese female patients, at baseline. As a result of the cardiac rehabilitation program, both groups had significant improvement in functional capacity (P=0.00, weight reduction (P=0.00, triglyceride (P=0.01 and P=0.02, respectively, low-density lipoprotein cholesterol (P=0.01, and low-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio (P=0.00 and P=0.003, respectively. As well, significant improvement was observed in high-density lipoprotein (P=0.01 only in obese female, and non-obese female had significant differences in total cholesterol (P=0.003.

    Since synthetic vitamins were used to fortify food and as supplements in the late 1930 s, vitamin intake has significantly increased. This has been accompanied by an increased prevalence of obesity, a condition associated with diabetes, hypertension, cardiovascular disease, asthma and cancer. Paradoxically, obesity is often associated with low levels of fasting serum vitamins, such as folate and vitamin D. Recent studies on folic acid fortification have revealed another paradoxical phenomenon: obesity exhibits low fasting serum but high erythrocyte folate concentrations, with high levels of serum folate oxidation products. High erythrocyte folate status is known to reflect long-term excess folic acid intake, while increased folate oxidation products suggest an increased folate degradation because obesity shows an increased activity of cytochrome P450 2E1, a monooxygenase enzyme that can use folic acid as a substrate. There is also evidence that obesity increases niacin degradation, manifested by increased activity/expression of niacin-degrading enzymes and high levels of niacin metabolites. Moreover, obesity most commonly occurs in those with a low excretory reserve capacity(e.g., due to low birth weight/preterm birth) and/or a low sweat gland activity(black race and physical inactivity). These lines of evidence raise the possibility that low fasting serum vitamin status in obesity may be a compensatory response to chronic excess vitamin intake, rather than vitamin deficiency, and that obesity could be one of the manifestations of chronic vitamin poisoning. In this article, we discuss vitamin paradox in obesity from the perspective of vitamin homeostasis.

However, understanding that a close relation exists between obesity prevalence and childhood obesity, which increased in recent years both across the world and in our country, and many diseases such as hypertension, diabetes, cardiovascular diseases changed the opinion of both of health care professionals and the society about childhood obesity in Turkey, like it changed the opinion in all around the world. Although there are no studies in our country, which have been conducted to investigate obesity prevalence and affecting factors in children nationwide, it is reported in studies carried out in various cities that rate of overweight children in preschool children is between 4-13%, whereas rate of obese children is between 9-27%. In the literature, a positive correlation was found between the frequency of taking the children to fast-food restaurants, compelling children to eat foods on their dishes, one or two of the parents being obese and obesity of children in Turkey. In this review will focus on the risk factors of childhood obesity in Turkey. (Journal of Current Pediatrics 2013; 11: 27-30

    Childhood obesity has reached epidemic levels in developed as well as in developing countries. Overweight and obesity in childhood are known to have significant impact on both physical and psychological health. Overweight and obese children are likely to stay obese into adulthood and more likely to develop non-communicable diseases like diabetes and cardiovascular diseases at a younger age. The mechanism of obesity development is not fully understood and it is believed to be a disorder with multiple causes. Environmental factors, lifestyle preferences, and cultural environment play pivotal roles in the rising prevalence of obesity worldwide. In general, overweight and obesity are assumed to be the results of an increase in caloric and fat intake. On the other hand, there are supporting evidence that excessive sugar intake by soft drink, increased portion size, and steady decline in physical activity have been playing major roles in the rising rates of obesity all around the world. Childhood obesity can profoundly affect children's physical health, social, and emotional well-being, and self esteem. It is also associated with poor academic performance and a lower quality of life experienced by the child. Many co-morbid conditions like metabolic, cardiovascular, orthopedic, neurological, hepatic, pulmonary, and renal disorders are also seen in association with childhood obesity. PMID:25949965

    Full Text Available Prevalence of pediatric obesity continues to rise worldwide. Increasing the number of health care practitioners as well as pediatricians with expertise in obesity treatment is necessary. Because many obese patients suffer obesity-associated cardiovascular, metabolic and other health complications that could increase the severity of obesity, it is fundamental not only to identify the child prone to obesity as early as possible, but to recognize, treat and monitor obesity-related diseases during adolescence. This short review outlines the treatment of pediatric obesity that may have applications in the primary care setting. It examines current information on eating behavior, sedentary behavior, and details studies of multidisciplinary, behavior-based, obesity treatment programs. We also report the less common and more aggressive forms of treatment, such as medication and bariatric surgery. We emphasize that health care providers have the potential to improve outcomes by performing early identification, helping families create the best possible home environment, and by providing structured guidance to obese children and their families.

    Full Text Available Background: Surgical intervention has been recently advocated in the treatment of morbid obesity. The objective of this study was to review surgery as an alternative in the treatment of morbidly obese adolescents. Materials and Methods: This research was conducted by searching English websites such as PubMed, Up to Date, and Google Scholar, as well as some Persian websites including SID, Iranmedex, and Magiran. Articles published from 2000 to 2010 on interventional and clinical trials were reviewed for treatment of morbid obesity in adolescents. Keywords used in internet searches include obesity; adolescence; and surgery.Results: The results obtained from the studies indicated that 4% of American adolescents suffer from morbid obesity. So far, pharmacological treatment and other approaches toward this type of obesity have been inefficient. Hence, surgery was employed as one of the new approaches to the treatment of this disorder. According to the National Health Institute criteria, in the treatment of adolescent candidates for surgery, anthropometric measurements are performed together with the measurement of other co-morbidities of obesity. Adolescents whose percentiles are ≥99 are considered as morbidly obese patients. Conclusion: The results of the studies suggested that for the extremely obese adolescents, who do not respond to other types of medical interventions within 6 months, surgery can be performed. Adolescents with BMI of ≥40 kg/m2 and skeletal maturity, or those with co morbidities of obesity, or 13-year-old girls and boys ≥15 years of age can be candidates for surgery. However, the side effects of obesity should not be neglected. Therefore, before the adolescent obesity become morbid obesity, preventive measures should be taken through changes in lifestyle.

    Full Text Available Obesity is an increasing public health concern worldwide. According to the latest Organization for Economic Co-operation and Development (OECD report (2014, the incidence of child obesity in Korea has exceeded the OECD average. To better understand and control this condition, the present study examined the composition of the gut microbial community in normal and obese adolescents. Fecal samples were collected from 67 obese (body mass index [BMI] ≥ 30 kg/m2, or ≥ 99th BMI percentile and 67 normal (BMI < 25 kg/m2 or < 85th BMI percentile Korean adolescents aged 13-16 years and subjected to 16S rRNA gene sequencing. Analysis of bacterial composition according to taxonomic rank (genus, family, and phylum revealed marked differences in the Bacteroides and Prevotella populations in normal and obese samples (p < 0.005 at the genus and family levels; however, there was no difference in the Firmicutes-to-Bacteroidetes (F/B ratio between normal and obese adolescents samples at the phylum level (F/B normal = 0.50 ± 0.53; F/B obese = 0.56 ± 0.86; p = 0.384. Statistical analysis revealed a significant association between the compositions of several bacterial taxa and child obesity. Among these, Bacteroides and Prevotella showed the most significant association with BMI (p < 0.0001 and 0.0001, respectively. We also found that the composition of Bacteroides was negatively associated with triglycerides (TG, total cholesterol, and high-sensitive C-reactive protein (hs-crp (p = 0.0049, 0.0023, and 0.0038, respectively levels, whereas that of Prevotella was positively associated with TG and hs-crp levels (p = 0.0394 and 0.0150, respectively. We then applied the association rule mining algorithm to generate "rules" to identify the association between the populations of multiple bacterial taxa and obesity; these rules were able to discriminate obese from normal states. Therefore, the present study describes a systemic approach to identify the association

    Malaysia is ranked as a country with the most obese population in the Southeast Asia region, and placed sixth in the Asia Pacific. Obesity does not only influence the persons' mobility and quality of health, but could also link to medical leaves and absenteeism affecting the overall workforce productivity and efficiency. Routine physical activity is essential for good health and it is particularly important for those who are trying to lose weight or to maintain a healthy weight. However, it is disheartening to note that only 32.6 percent Malaysians above the age of 15 are involved in physical exercise or vigorous sports. There is an emergence of many types of hydrotherapy system, which are either active or passive and these can be at hospital settings, public places or in individual homes. Such hydrotherapy, if properly programmed can promote the physical activity amongst the obese in Malaysia. Current research on the use of active and passive hydrotherapy for obesity treatment was carried out. Subjects of both sexes and diverse age ranges, immersed themselves in a heated pool within hospital setting and in a bath tubs with high energy turbulent movement of medium temperature water. These hydrotherapy sessions provide a form of physical exercise in water as compared to on the land exercise. The findings of the hydrotherapy sessions have shown encouraging results. Quantitative data was analysed, with the help of descriptive statistics and paired sample t-test. Qualitative data was analysed manually with help of thematic analysis and specialised qualitative assessment software. This study reveals that hydrotherapy has improved patient's mobility, flexibility and exercise capability. Results reveal the reduction in the weight of subjects, with both quantitative and qualitative data results show that Hydrotherapy improved the quality of life in term of body pain reduction and general health improvement. Therefore, it can be concluded that the hydrotherapy can be seen

In addition, the percentage of depressive obese patients was significantly higher (55.1%, χ2 (267.1=22.64, p<0.001. There was significant correlation of BMI and BDI scores (r=0.246, p<0.001. The number of women with depression was significantly higher in comparison to men (χ2 (267.1=4.261, p=0.039.Women also had higher average BDI score (p = 0.003. MANOVA showed that BDI score was influenced by gender (F(267.1=8.936, p=0.030 and nutritional status ( F(267.1=6.115, p=0.014, but combined effect of the abovementioned moderators was not significant. Conclusion Depression is ten times more frequent in obese patients undergoing the obesity treatment vs. general population and, therefore, screening for depression is needed. Special attention should be paid to women and more obese patients due to higher incidence of depression in these groups.

    This study investigated cardiovascular functioning, mood, and eating-related psychological factors at rest and in response to mental stress in three groups of women: 1) Obese women with binge eating disorder (BED; n=9); 2) obese non-BED women (n=15); and 3) normal weight (NW) non-BED women (n=15). Compared to both obese and NW non-BED women, obese women with BED showed heightened overall blood pressure and reported greater depression symptoms, perceived stress, and eating-related psychopathology. Additionally, obese women with BED reported greater overall negative affect and state anxiety compared to obese non-BED women. The heart rate response to stress was blunted in the obese BED group compared to the other groups, but this effect was no longer significant after controlling for baseline differences in depression. Correlational analyses revealed a positive association between stress-induced changes in hunger and cardiovascular measures only in obese women with BED. Longitudinal studies are needed to determine if stress dysregulation and stress-induced increases in hunger contribute to the onset and/or maintenance of BED. In particular, studies utilizing an additional NW BED control group are warranted in order to further examine the impact of BED above and beyond the impact of obesity on psychophysiological functioning and to inform the growing literature regarding stress-related factors that distinguish the BED and obesity phenotypes.

    Obesity is a problem of public health, seen as a "moral panic," which disables the obese person from social acceptance. For obese nutritionists the paradox between the premises of their jobs and their state of morbidity makes the debate complex by the conflict with the professional identity. This study sought to bring to discussion the meanings of health care adopted by obese nutritionists in Salvador and to understand their experiences with their obesity in everyday life. The study was based on a qualitative approach, through semi-structured interviews with eight narratives on being an obese nutritionist, analysed under hermeneutics basis. The research revealed that being obese generates a stigma which is worse to the nutritionist, now seen simultaneously as unable to care for oneself and on being obese. Some of the stories of suffering seen on job routine are: strangeness of the body, social exclusion, strategies for defence on the relation professional-patient, desperate rely on miraculous diet plans which are far away from the scientific discourse, and the obese body seen as imprisonment. It is concluded that institutions of public health must have knowledge of this problem and must establish strategies to the condition of obese nutritionists, considering that this contradiction may happen on different occupations.

    Overweight and obesity is associated with a broad variety of stigmatization and discrimination in every day live. Obese people have more difficulties in finding a job, have a lower income, and are less often seen in leadership positions. In society, responsibility for the weight situation in seen as lying by the individuals affected altogether, leading to chronic stress, problems with self esteem and perception of loss of control. As a consequence, there is an increased risk for developing serious psychological problems such as affective and anxiety disorders. As a reaction, coping strategies to deal with the psychological pressure such as dysfunctional eating behavior, binge eating and physical inactivity are used. Females, people belonging to another ethnic or social minority, adolescents and people with eating disorders are considered at increased risk of psychological distress. Psychological vulnerabilities and the consequences of stigmatization need to be considered. Moreover, perceived behavioral control and self esteem are key aspects of to be addressed on the treatment.

    Full Text Available Abstract Obesity is a chronic disease characterized by persistent low-grade inflammation with alterations in gut motility. Motor abnormalities suggest that obesity has effects on the enteric nervous system (ENS, which controls virtually all gut functions. Recent studies have revealed that the gut microbiota can affect obesity and increase inflammatory tone by modulating mucosal barrier function. Furthermore, the observation that inflammatory conditions influence the excitability of enteric neurons may add to the gut dysfunction in obesity. In this article, we discuss recent advances in understanding the role of gut microbiota and inflammation in the pathogenesis of obesity and obesity-related gastrointestinal dysfunction. The potential contribution of sirtuins in protecting or regulating the circuitry of the ENS under inflamed states is also considered.

    Obesity, induced by unhealthy lifestyle choices, could be involved in the development of chronic diseases like type 2 diabete. Obesity is largely due to the imbalance of energy intake and expenditure, therefore we have put more emphasis on the amount of macronutrients including carbohydrates, fats and proteins as dietary therapy for obesity and related-conditions. On the other hand, several studies revealed obese or diabetic patients were more likely to have micronutrient deficiencies such as vitamins and minerals. Besides the effects on bone metabolism, vitamin D and calcium might contribute to metabolic disorder accompanied by obesity. However, it has not been concluded supplementation of these two nutrients has a benefit in obese or diabetic individuals. Further studies are needed. PMID:26923970

    2013-09-01

    Full Text Available Chronobiology is a word derived from three Greek stems: kronos for time, bios for life and logos for study. From microarrays studies, now it is accepted that 10-30% of the human genome is under the control of circadian molecular clocks. This implies that most behavioral, physiological and biochemical variables display circadian rhythms in their expression. In its simplest form, circadian clocks are composed of a set of proteins that generate self-sustained circadian oscillations. The molecular clock comprises two transcription factors, CLOCK and BMAL1, whereas PERs and CRYs are responsible for the negative limb. One of the most important questions related to the circadian system and obesity, was to elucidate if adipose tissue displayed circadian rhythmicity or whether it had an internal peripheral clock. Our group of research has provided an overall view of the internal temporal order of circadian rhythms in human adipose tissue. A new concept related to illness is Chronodisruption (CD. It is defined as a relevant disturbance of the internal temporal order of physiological and behavioral circadian rhythms. In our modern society, CD may be common in several conditions such as jet lag, shift work, light at night, or social jet lag. In addition clock gene polymorphisms and aging may have also chronodisruptive effects. Our group has also demonstrated that Obesity and CD are also highly interconnected. With the help of chronobiology we can reach a new view of obesity considering not only "what" are the factors involved in obesity, but also "when" these factors are produced.

    Full Text Available Glucocorticoids, prolactin and growth hormone play an important role in the regulation of metabolic homeostasis. Hypercortisolism, hyperprolactinemia and growth hormone deficiency lead to an increase in body weight due to visceral fat accumulation. Mechanisms of development of obesity in various endocrine diseases are different. Adequate correction of hormonal disorders usually is accompanied by a decrease in body weight and the improvement of metabolic parameters.

    Despite all modern advances in medicine, an effective drug treatment of obesity has not been found yet. Discovery of leptin two decades ago created hopes for treatment of obesity. However, development of leptin resistance has been a big obstacle, mitigating a leptin-centric treatment of obesity. Here, by using in silico drug-screening methods, we discovered that Celastrol, a pentacyclic triterpene extracted from the roots of Tripterygium Wilfordi (thunder god vine) plant, is a powerful anti-obesity agent. Celastrol suppresses food intake, blocks reduction of energy expenditure, and leads to up to 45% weight loss in hyperleptinemic diet-induced obese (DIO) mice by increasing leptin sensitivity, but it is ineffective in leptin-deficient (ob/ob) and leptin receptor-deficient (db/db) mouse models. These results indicate that Celastrol is a leptin sensitizer and a promising agent for the pharmacological treatment of obesity. PMID:26000480

    Obesity develops from an imbalance of energy homeostasis and is associated with chronic low-grade inflammation in white adipose tissues (WAT). Inflammation is involved in the pathophysiology of many obesity-induced disorders including insulin resistance and diabetes. Increasing evidence has shown that dietary leucine supplementation positively affects the parameters associated with obesity and obesity-related metabolic disorders. The beneficial effects include increased loss of body weight, reduced WAT inflammation, improved lipid and glucose metabolism, enhanced mitochondrial function, and preserved lean body mass. Although these beneficial effects have not been clearly established, dietary leucine supplementation, either alone or as part of a therapeutic regimen, may be a good nutritional tool in the prevention and management of obesity and obesity-induced metabolic disorders.

    Obesity prevalence is increasing in many countries at alarming levels. A difficulty in the conception of policies to reverse these trends is the identification of the drivers behind the obesity epidemics. Here, we implement a spatial spreading analysis to investigate whether obesity shows spatial correlations, revealing the effect of collective and global factors acting above individual choices. We find a regularity in the spatial fluctuations of their prevalence revealed by a pattern of scale-free long-range correlations. The fluctuations are anomalous, deviating in a fundamental way from the weaker correlations found in the underlying population distribution indicating the presence of collective behavior, i.e., individual habits may have negligible influence in shaping the patterns of spreading. Interestingly, we find the same scale-free correlations in economic activities associated with food production. These results motivate future interventions to investigate the causality of this relation providing guidance for the implementation of preventive health policies.

  20. Bacteria, viruses, and hypothalamic inflammation: Potential new players in obesity

    Directory of Open Access Journals (Sweden)

    Magdalena Wierucka-Rybak

    2014-03-01

    Full Text Available Being overweight and obese has become an increasingly serious clinical and socioeconomic problem worldwide. The rapidly rising prevalence of obesity has prompted studies on modifiable, causative factors and novel treatment options for this disorder. Recent evidence indicates that excessive weight gain that leads to being overweight and obese may result from alterations in gut microflora. Studies in humans and animals demonstrated that the composition of gut microbiota may differ in lean and obese subjects, suggesting that these differences result in the increased efficiency of caloric extraction from food, enhanced lipogenesis, and impaired central and peripheral regulation of energy balance. Other studies revealed an excessive increase in body weight in a significant percentage of people infected with human adenoviruses SMAM-1 and Ad-36. Dysregulation of adipocyte function by viruses appears to be the most likely cause of excessive fat accumulation in these individuals. Studies on the pathomechanisms related to the pathogenesis of obesity indicated that a high-fat diet triggers the inflammatory response in the hypothalamus, an event that promotes weight gain and further defends elevated body weight through the initiation of central leptin and insulin resistance and impairment of regenerative capacity of hypothalamic neurons. Exposure to a high-calorie diet appears to predispose individuals to obesity not only because of excessive caloric intake but also because of the induction of microbiota- and central inflammatory response-dependent changes that lead to a dysregulation of energy balance.

  1. Midkine, a potential link between obesity and insulin resistance.

    Directory of Open Access Journals (Sweden)

    Nengguang Fan

    Full Text Available Obesity is associated with increased production of inflammatory mediators in adipose tissue, which contributes to chronic inflammation and insulin resistance. Midkine (MK is a heparin-binding growth factor with potent proinflammatory activities. We aimed to test whether MK is associated with obesity and has a role in insulin resistance. It was found that MK was expressed in adipocytes and regulated by inflammatory modulators (TNF-α and rosiglitazone. In addition, a significant increase in MK levels was observed in adipose tissue of obese ob/ob mice as well as in serum of overweight/obese subjects when compared with their respective controls. In vitro studies further revealed that MK impaired insulin signaling in 3T3-L1 adipocytes, as indicated by reduced phosphorylation of Akt and IRS-1 and decreased translocation of glucose transporter 4 (GLUT4 to the plasma membrane in response to insulin stimulation. Moreover, MK activated the STAT3-suppressor of cytokine signaling 3 (SOCS3 pathway in adipocytes. Thus, MK is a novel adipocyte-secreted factor associated with obesity and inhibition of insulin signaling in adipocytes. It may provide a potential link between obesity and insulin resistance.

  2. Chronodisruption and Obesity

    Anna Meiliana

    2015-12-01

    Full Text Available BACKGROUND: Attempts to understand the causes of obesity and develop new therapeutic strategies have mostly focused on caloric intake and energy expenditure. Recent studies have shown that the circadian clock controls energy homeostasis by regulating circadian expression and/or activity of enzymes, hormones, and transport systems involved in metabolism. Moreover, disruption of circadian rhythms leads to obesity and metabolic disorders. CONTENT:Regularly alternating periods of light and darkness, such as normally occur with the rising and the setting of the sun, are essential for the maintenance of undisturbed circadian rhythms in all organisms including humans. The light-dark environment, as detected by specialized photoreceptors in the retinas, impacts the endogenous circadian clock in the anterior hypothalamus, the suprachiasmatic nuclei. These nuclei, via both neural and humoral signals, communicate with cells throughout the organism to establish regular circadian rhythms. The introduction of artificial sources of light roughly 150 years ago has significantly undermined the naturally occurring light-dark environment and, likewise, has disturbed circadian rhythms since light is now available at unusual times, i.e., at night. Light at night is known to cause circadian disruption and melatonin suppression. Many potentially pathophysiological consequences of these artificial light-mediated changes, include cancer, cardiovascular diseases, insomnia, metabolic syndrome, diabetes, and cognitive disorders may be aggravated by the increased exposure to light at night, which is inevitable in well-developed societies that have undergone extensive electrification. SUMMARY: Therefore, it is plausible that resetting of the circadian clock can be used as a new approach to attenuate obesity. Feeding regimens, such as restricted feeding, calorie restriction and intermittent fasting, provide a time cue and reset the circadian clock and

  4. Altered Respiratory Physiology in Obesity

    Krishnan Parameswaran

    2006-01-01

    Full Text Available The major respiratory complications of obesity include a heightened demand for ventilation, elevated work of breathing, respiratory muscle inefficiency and diminished respiratory compliance. The decreased functional residual capacity and expiratory reserve volume, with a high closing volume to functional residual capacity ratio of obesity, are associated with the closure of peripheral lung units, ventilation to perfusion ratio abnormalities and hypoxemia, especially in the supine position. Conventional respiratory function tests are only mildly affected by obesity except in extreme cases. The major circulatory complications are increased total and pulmonary blood volume, high cardiac output and elevated left ventricular end-diastolic pressure. Patients with obesity commonly develop hypoventilation and sleep apnea syndromes with attenuated hypoxic and hypercapnic ventilatory responsiveness. The final result is hypoxemia, pulmonary hypertension and progressively worsening disability. Obese patients have increased dyspnea and decreased exercise capacity, which are vital to quality of life. Decreased muscle, increased joint pain and skin friction are important determinants of decreased exercise capacity, in addition to the cardiopulmonary effects of obesity. The effects of obesity on mortality in heart failure and chronic obstructive pulmonary disease have not been definitively resolved. Whether obesity contributes to asthma and airway hyper-responsiveness is uncertain. Weight reduction and physical activity are effective means of reversing the respiratory complications of obesity.

    Obese patients have complex needs that complicate their care during hospitalization. These patients often have comorbid conditions, including hypertension, heart failure, obstructive sleep apnea, pressure ulcers, and difficulty with mobility. Obese patients may be well served in the progressive care setting because they may require more intensive nursing care than can be delivered in a general care unit. Progressive care nurses have core competencies that enable them to safely and effectively care for obese patients. A plan of care with interdisciplinary collaboration illustrates the integrative care for obese progressive care patients. (Critical Care Nurse 2016; 36[4]:58-63). PMID:27481802

Approximately 43 million individuals are obese, 21–24% children and adolescents are overweight, and 16–18% of individuals have abdominal obesity. The prevalence of obesity is highest among specific ethnic groups. Obesity increases the risk of heart diseases in children and adults. Childhood obesity predisposes the individual to insulin resistance and type 2 diabetes, hypertensio...

  17. Functional MRI and neurophysiological aspects of obesity

    International Nuclear Information System (INIS)

    Functional magnetic resonance imaging studies have revealed that metabolic signals and food stimuli activate the mesocorticolimbic neural network involved in processing the reward system. Activation is influenced by obesity and hunger and many recent brain imaging studies have detected that food and drug stimuli activate many of the same reward circuits. These findings have implications for obesity prevention and therapy. Educational efforts need to be directed towards those at increased risk of becoming obese and the food industry has to be involved in providing and promoting healthier food options. Given that visual food stimuli are potent triggers of desire, seductive advertising of high calorie foods directed towards children should be curtailed. The application of non-invasive brain imaging methodologies to the study of hedonic and homeostatic eating behavior represents a novel and important experimental approach. Further advances in imaging technology and improved experimental designs will provide new and important insights into human ingestive behavior that may lead to new developments in behavioral and pharmacological therapies.

  18. Perceived weight discrimination and obesity.

    Directory of Open Access Journals (Sweden)

    Angelina R Sutin

    Full Text Available Weight discrimination is prevalent in American society. Although associated consistently with psychological and economic outcomes, less is known about whether weight discrimination is associated with longitudinal changes in obesity. The objectives of this research are (1 to test whether weight discrimination is associated with risk of becoming obese (Body Mass Index≥30; BMI by follow-up among those not obese at baseline, and (2 to test whether weight discrimination is associated with risk of remaining obese at follow-up among those already obese at baseline. Participants were drawn from the Health and Retirement Study, a nationally representative longitudinal survey of community-dwelling US residents. A total of 6,157 participants (58.6% female completed the discrimination measure and had weight and height available from the 2006 and 2010 assessments. Participants who experienced weight discrimination were approximately 2.5 times more likely to become obese by follow-up (OR = 2.54, 95% CI = 1.58-4.08 and participants who were obese at baseline were three times more likely to remain obese at follow up (OR = 3.20, 95% CI = 2.06-4.97 than those who had not experienced such discrimination. These effects held when controlling for demographic factors (age, sex, ethnicity, education and when baseline BMI was included as a covariate. These effects were also specific to weight discrimination; other forms of discrimination (e.g., sex, race were unrelated to risk of obesity at follow-up. The present research demonstrates that, in addition to poorer mental health outcomes, weight discrimination has implications for obesity. Rather than motivating individuals to lose weight, weight discrimination increases risk for obesity.

    We investigate the relationship between GP supply and body mass index (BMI) in England. Individual level BMI is regressed against area whole time equivalent GPs per 1,000 population plus individual and area level covariates. Using IV models we find that a 10% increase in GP supply is associated with a mean reduction in BMI of around 1 kg/m2 (around 4% of mean BMI). Our study suggests that better primary care in the form of reduced list sizes per GP can improve the management of obesity.

    Weight management interventions during adolescence are challenging. Migration adds complexity to this problem, making migrant families more vulnerable. Teenagers confront families to new values transmitted by the host society: opulence, junk food, video games. Obesity should not be seen as a single issue of calories-excess, but must be considered as being part of a larger problem, which takes into account the context of the familial and societal life of the migrants. The caregivers must have an overall view of the situation to provide appropriate approaches to weight management. PMID:22787729

    Full Text Available Abstract Childhood obesity has reached epidemic levels in developed countries. Twenty five percent of children in the US are overweight and 11% are obese. Overweight and obesity in childhood are known to have significant impact on both physical and psychological health. The mechanism of obesity development is not fully understood and it is believed to be a disorder with multiple causes. Environmental factors, lifestyle preferences, and cultural environment play pivotal roles in the rising prevalence of obesity worldwide. In general, overweight and obesity are assumed to be the results of an increase in caloric and fat intake. On the other hand, there are supporting evidence that excessive sugar intake by soft drink, increased portion size, and steady decline in physical activity have been playing major roles in the rising rates of obesity all around the world. Consequently, both over-consumption of calories and reduced physical activity are involved in childhood obesity. Almost all researchers agree that prevention could be the key strategy for controlling the current epidemic of obesity. Prevention may include primary prevention of overweight or obesity, secondary prevention or prevention of weight regains following weight loss, and avoidance of more weight increase in obese persons unable to lose weight. Until now, most approaches have focused on changing the behaviour of individuals in diet and exercise. It seems, however, that these strategies have had little impact on the growing increase of the obesity epidemic. While about 50% of the adults are overweight and obese in many countries, it is difficult to reduce excessive weight once it becomes established. Children should therefore be considered the priority population for intervention strategies. Prevention may be achieved through a variety of interventions targeting built environment, physical activity, and diet. Some of these potential strategies for intervention in children can be

    Phthalates are commonly used as plasticizers and vehicles for cosmetic ingredients. Phthalate metabolites have documented biochemical activity including activating peroxisome proliferator-activated receptor and antiandrogenic effects, which may contribute to the development of obesity. In vitro and in vivo studies suggest that phthalates have significant effects on the development of obesity, especially after prenatal exposure at low doses. Although few studies have examined the effects of phthalate on obesity development in humans, some work has shown that phthalates affect humans and animals similarly. In this paper, we review the possible mechanisms of phthalate-induced obesity, and discuss evidence supporting the role of phthalates in the development of obesity in humans. PMID:25077088

    Full Text Available Increasing evidence suggests that alteration of gut microbiota ('dysbiosis' can lead to a number of diseases, including obesity, which affects a large population in the world and is now a global health issue. The mechanisms of gut microbiota-mediated obesity are just being explored and characterized in recent years. It has been suggested that dysbiosis of gut microbiota contributes to obesity development mainly in three ways: affecting energy harvest, altering host gene expression, and triggering chronic inflammation. Among the factors that determine and influence gut microbiota composition, diet is one of the best characterized in human and animal studies, and has been long linked with weight gain or loss. In this review, we will discuss recent advances of mechanisms through which gut microbiota dysbiosis leads to obesity. We will further discuss the underlying causes of obesity-related gut microbiota, highlighting dietary effects.

    2016-03-01

    Obesity is a heterogeneous condition with multifactorial genesis (genetic predisposition, life-style, psychosocial situation), but there is a relatively homogeneous negative stereotype of obese individuals, because overweight and obesity are seen as self-inflicted disorders caused by physical inactivity and disorderd eating behavior. Obese individuals are confronted with far-reaching stigmatization and discrimination. Typical stereotypes are laziness, unattractiveness, work refusal. This negative image by the environment contributes to negative self-awareness and self-stigmatization, accompanied by a poor self-esteem and feelings of poor self-control and reduced self-efficacy, resulting in poor constructive coping strategies for overweight reduction. In addition, a disturbed body image combined with deep dissatisfaction with their own body is often found in many obese individuals. There is not always a close connection between body weight and body dissatisfaction. Young women and individuals with a binge eating disorder often show an increased body dissatisfaction as well.

    Stanton, Rosemary A

    2015-03-01

    We live in an 'obesogenic environment' where we are constantly bombarded with choices that encourage us to move less and eat more. Many factors influence our dietary choices, including the expert marketers who advise manufacturers on ways to encourage the population to buy more, especially profitable, palatable 'ultra-processed' foods. Supermarkets themselves have become skilled in manipulating buying behaviour, using their layout and specific product placement as well as advertising to maximise purchases of particular foods. Increasingly, supermarkets push their own 'house' brands. Those marketing fast foods also use persuasive tactics to attract customers, especially children who they entice with non-food items such as promotional or collectable toys. There is no mystery to the increase in obesity: our energy intake from foods and drinks has increased over the same period that energy output has decreased. Obesity has a range of relevant factors, but there is little doubt that marketing from supermarkets and fast food retailers has played a role. PMID:26627090

  9. Starches, Sugars and Obesity

    Directory of Open Access Journals (Sweden)

    Erik E. J. G. Aller

    2011-03-01

    Full Text Available The rising prevalence of obesity, not only in adults but also in children and adolescents, is one of the most important public health problems in developed and developing countries. As one possible way to tackle obesity, a great interest has been stimulated in understanding the relationship between different types of dietary carbohydrate and appetite regulation, body weight and body composition. The present article reviews the conclusions from recent reviews and meta-analyses on the effects of different starches and sugars on body weight management and metabolic disturbances, and provides an update of the most recent studies on this topic. From the literature reviewed in this paper, potential beneficial effects of intake of starchy foods, especially those containing slowly-digestible and resistant starches, and potential detrimental effects of high intakes of fructose become apparent. This supports the intake of whole grains, legumes and vegetables, which contain more appropriate sources of carbohydrates associated with reduced risk of cardiovascular and other chronic diseases, rather than foods rich in sugars, especially in the form of sugar-sweetened beverages.

    2009-01-01

    Full Text Available High fat meals induce oxidative stress, which is associated with the pathogenesis of disease. Obese individuals have elevated resting biomarkers of oxidative stress compared to non-obese. We compared blood oxidative stress biomarkers in obese (n = 14; 30 ± 2 years; BMI 35 ± 1 kg•m−2 and non-obese (n = 16; 24 ± 2 years; BMI 23 ± 1 kg•m−2 women, in response to a high fat meal. Blood samples were collected pre-meal (fasted, and at 1, 2, 4 and 6 hours post meal, and assayed for trolox equivalent antioxidant capacity (TEAC, xanthine oxidase activity (XO, hydrogen peroxide (H2O2, malondialdehyde (MDA, triglycerides (TAG, and glucose. An obesity status effect was noted for all variables (p 0.05, contrasts revealed greater values in obese compared to non-obese women for XO, H2O2, MDA, TAG and glucose, and lower values for TEAC at times from 1–6 hours post feeding (p ≤ 0.03. We conclude that young, obese women experience a similar pattern of increase in blood oxidative stress biomarkers in response to a high fat meal, as compared to non-obese women. However, the overall oxidative stress is greater in obese women, and values appear to remain elevated for longer periods of time post feeding. These data provide insight into another potential mechanism related to obesity-mediated morbidity.

    Abstract Obesity prevalence remains high in the United States (US), and is rising in most other countries. This is a repeated cross-sectional study using a nationally representative sample of the National Health and Nutrition Examination Survey 1999 to 2012. Multivariate logistic regression analyses were separately performed for adults (n = 37,639) and children/adolescents (n = 28,282) to assess the associations between the length of time in the US, and the prevalences of obesity and diabetes. In foreign-born adults, the prevalences of both obesity and diabetes increased with the length of time in the US, and ≥20 years in the US was associated with significantly higher rates of obesity (adjusted odds ratio [aOR] 2.32, 95% confidence interval [CI] 1.22–4.40, P = 0.01) and diabetes (aOR 4.22, 95% CI 1.04–17.08, P = 0.04) compared with year in the US. In children/adolescents, obesity prevalence was significantly higher in those born in the US than those who had been in the US for year (aOR 3.15, 95% CI 1.51–6.56, P = 0.002). When analyzed by year, obesity prevalence was significantly higher in US-born than in foreign-born adults from 1999 to 2012. On the other hand, the gap in obesity prevalence between US-born and foreign-born children/adolescents decreased from 1999 to 2011 due to a rapid increase in obesity prevalence among the foreign-born population, until there was no significant difference in 2011 to 2012. This study revealed that the risks of obesity and diabetes have increased in foreign-born US residents with time living in the US. However, the obesity gap between US-born and foreign-born populations is closing. PMID:27583867

    landlord. The percentage of obese people is highest in people who rented from councils or housing associations. The Chi-square test does not show any association between BMI and deprivation in this survey. The number of non-white people in the survey is very small and does not allow for further analysis. Conclusion and recommendations: This study revealed all age groups should be considered as a population target for prevention of obesity. Social factors such as level of education and housing tenure are associated with obesity as reported by other studies. Permanently ill or disabled people are more likely to be overweight and obese. The percentages of obesity are highest in people who rented homes from councils or housing associations which may be associated with ageing or medical conditions leading to less activity and a sedentary lifestyle. Prevention of obesity should be a priority of health policy. The increasing rate of overweight and obesity in all groups suggest that the whole community should be the focus including all age groups. Health promotion interventions should focus on both healthy eating interventions and increase physical activity.

    Obesity is a major worldwide health issue, with increasing prevalence in adults and children from developed and developing countries. Obesity causes several chronic diseases, including cardiovascular and respiratory diseases, osteoarthritis, hypertension, stroke, type II diabetes, obstructive sleep apnea, and several types of cancer. Previous genome-wide association studies have identified several genes associated with obesity, including LEP, LEPR, POMC, PCSK1, FTO, MC3R, MC4R, GNPDA2, TMEM18, QPCTL/GIPR, BDNF, ETV5, MAP2K5/SKOR1, SEC16B, SIM1, and TNKS/MSRA. However, most of these variants are found in the intronic or intergenic regions, making it difficult to elucidate the underlying mechanisms. Therefore, in this study, we performed a whole exome sequencing of the protein-coding regions in the total genome (exome) of two obese and one normal subject belonging to the same Thai family to identify the genes responsible for obesity. We identified 709 functional variants that were differentially expressed between obese and normal subjects; of these, 65 were predicted to be deleterious to protein structure or function. The minor allele frequency of 14 of these genes (ALOX5AP, COL9A2, DEFB126, GDPD4, HCRTR1, MLL3, OPLAH, OR4C45, PRIM2, RXFP2, TIGD6, TRPM8, USP49, and ZNF596) was low, indicating causal variants that could be associated with complex traits or diseases. Genotyping revealed HCRTR1, COL9A2, and TRPM8 to be associated with the regulation of feeding behavior and energy expenditure. These genes constituted a network of pathways, including lipid metabolism, signaling transduction, immune, membrane transport, and gene regulation pathways, and seemed to play important roles in obesity.

    With an increased prevalence of obesity in developed countries, associated chronic diseases rise in a parallel way. Morbidity secondary to overweight and obesity include type 2 diabetes, dislipemia, hypertension, heart disease, cerebrovascular disease, cholelithiasis, osteoarthritis, heart insufficiency, sleep apnoea, menstrual changes, sterility and psychological alterations. There is also a greater susceptibility to suffer some types of cancer, infections, greater risk of bacteremia and a prolonged time of wound healing after surgical operations. All these factors indicate that obesity exerts negative effects upon the immune system. Immune changes found in obesity and their possible interrelations are described in this article. Changes produced during obesity affect both humoral and cellular immunity. It is known that adipose tissue, together with its role as energy reserve in form of triglycerides, has important endocrine functions, producing several hormones and other signal molecules. Immune response can be deeply affected by obesity, playing leptin an important role. Properties of leptin, alterations of leptin levels in different situations and its changes with different medical and surgical therapies for obesity are described in this article. PMID:15672646

    The aim of this study was to investigate the prevalence of moderate and extreme obesity among an Irish obstetric population over a 10-year period, and to evaluate the obstetric features of such pregnancies. Of 31,869 women delivered during the years 2000-2009, there were 306 women in the study group, including 173 in the moderate or Class 2 obese category (BMI 35-39.9) and 133 in the extreme or Class 3 obese category (BMI > or = 40).The prevalence of obese women with BMI > or = 35 was 9.6 per 1000 (0.96%), with an upward trend observed from 2.1 per 1000 in the year 2000, to 11.8 per 1000 in the year 2009 (P = 0.001). There was an increase in emergency caesarean section (EMCS) risk for primigravida versus multigravid women, within both obese categories (P < 0.001). However, there was no significant difference in EMCS rates observed between Class 2 and Class 3 obese women, when matched for parity. The prevalence of moderate and extreme obesity reported in this population is high, and appears to be increasing. The increased rates of abdominal delivery, and the levels of associated morbidity observed, have serious implications for such women embarking on pregnancy.

    With the epidemic of childhood obesity, it is not uncommon for prescribers to puzzle over an appropriate drug dose for an obese child. Defining the optimum therapeutic dose of a drug relies on an understanding of pharmacokinetics and pharmacodynamics. Both these processes can be affected by body composition and the physiological changes that occur in obese children. As a rule of thumb, 75% of excess weight in obese subjects is fat mass, and the remainder lean mass. Although it is reasonable to assume that increases in fat mass alter the distribution of lipophilic drugs and increases in lean mass alter drug clearance, good quality and consistent clinical data supporting these assumptions are lacking for the majority of drugs. The relatively few clinical studies that have evaluated the impact of obesity have often been limited by poor design and insufficient sample size. Moreover, clinical studies conducted during drug development rarely include (or are required to include) obese subjects. Guidance on dosing obese children ought to be provided by drug manufacturers. This could be achieved by including obese patients in studies where possible, enabling the effect of body size on pharmacotherapy to be evaluated. This approach could be further augmented by the use of physiologically based-pharmacokinetic models during early (preclinical) development to predict the impact of obesity on drug disposition, and subsequent clinical studies later in development to provide confirmatory proof. In the meantime, for the majority of drugs already prescribed in children, particularly those where the therapeutic range is narrow or there is significant toxicity, the lack of a validated body size descriptor to use at the bedside means the choice of dose will rely on empirical experience and application of the precautionary principle.

    Obesity has become a serious public health problem worldwide, and dietary composition can play a role in its prevention and treatment. However, available literature on the impacts of different dietary factors on weight change is inconsistent, or even conflicting. In this review, we briefly summarized the mechanisms and influences of several major dietary determinants of weight change, with a focus on their potential in the prevention of weight gain or regain. We discussed the intake of fat, protein, total carbohydrates, fruits and vegetables, fibre, free sugars, fructose and sugar sweetened beverages, dietary energy density, portion size, eating outside home, glycaemic index and glycaemic load. Popular weight loss diets, including the Atkins diet, Weight Watchers, Ornish diet and Zone diet, are also briefly discussed for their safety and efficacy in the maintenance of weight loss.

    Full Text Available The power and significance of artwork in shaping human cognition is self-evident. The starting point for our empirical investigations is the view that the task of neuroscience is to integrate itself with other forms of knowledge, rather than to seek to supplant them. In our recent work, we examined a particular aspect of the appreciation of artwork using present-day functional magnetic resonance imaging (fMRI. Our results emphasised the continuity between viewing artwork and other human cognitive activities. We also showed that appreciation of a particular aspect of artwork, namely authenticity, depends upon the co-ordinated activity between the brain regions involved in multiple decision making and those responsible for processing visual information. The findings about brain function probably have no specific consequences for understanding how people respond to the art of Rembrandt in comparison with their response to other artworks. However, the use of images of Rembrandt’s portraits, his most intimate and personal works, clearly had a significant impact upon our viewers, even though they have been spatially confined to the interior of an MRI scanner at the time of viewing. Neuroscientific studies of humans viewing artwork have the capacity to reveal the diversity of human cognitive responses that may be induced by external advice or context as people view artwork in a variety of frameworks and settings.

    Full Text Available Background: Obesity is a fast growing problem in the developing countries like India and is now known to be associated with increased health risk. Realizing the fact that the obesity in adolescent age group does not receive the deserved attention in the prevention and control programme, the present study was undertaken on 585 adolescent subjects studying in one college and three schools. Aims and Objectives: 1. To study the prevalence of overweight and obesity in adolescent population. 2. To find the association of body mass index (BMI with important parameters like skin fold thickness, waist circumference and waist to hip ratio. Methods: It was a cross sectional observational study. The study population was school and college going adolescents in the age group of 11-19 years. The estimated sample size for present study is 585 students. The subjects were screened by body mass index, skin fold thickness, waist circumference and waist to hip ratio. Results: The prevalence of overweight and obesity was 19.14% and 4.44% respectively. It was found that there was strong association between the waist circumference with overweight and obesity. Similarly a strong association between waist to hip ratio with overweight and obesity has been found. Also it was found that there was a strong association between skin fold thickness with overweight and obesity. Skin-fold thickness has more sensitivity as compared to waist circumference and waist to hip ratio. Waist to hip ratio has got maximum specificity amongst all but when both sensitivity and specificity criteria are considered together waist circumference stands out. Conclusion: It was found that the prevalence of overweight and obesity was 19.14% and 4.44% respectively. Skin-fold thickness has more sensitivity as compared waist circumference and waist to hip ratio. Waist to hip ratio has got maximum specificity.

  15. Fetal Programming of Obesity: Maternal Obesity and Excessive Weight Gain

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available The prevalence of obesity is an increasing health problem throughout the world. Maternal pre-pregnancy weight, maternal nutrition and maternal weight gain are among the factors that can cause childhood obesity. Both maternal obesity and excessive weight gain increase the risks of excessive fetal weight gain and high birth weight. Rapid weight gain during fetal period leads to changes in the newborn body composition. Specifically, the increase in body fat ratio in the early periods is associated with an increased risk of obesity in the later periods. It was reported that over-nutrition during fetal period could cause excessive food intake during postpartum period as a result of metabolic programming. By influencing the fetal metabolism and tissue development, maternal obesity and excessive weight gain change the amounts of nutrients and metabolites that pass to the fetus, thus causing excessive fetal weight gain which in turn increases the risk of obesity. Fetal over-nutrition and excessive weight gain cause permanent metabolic and physiologic changes in developing organs. While mechanisms that affect these organs are not fully understood, it is thought that the changes may occur as a result of the changes in fetal energy metabolism, appetite control, neuroendocrine functions, adipose tissue mass, epigenetic mechanisms and gene expression. In this review article, the effects of maternal body weight and weight gain on fetal development, newborn birth weight and risk of obesity were evaluated, and additionally potential mechanisms that can explain the effects of fetal over-nutrition on the risk of obesity were investigated [TAF Prev Med Bull 2014; 13(5.000: 427-434

    2015-03-01

    Overweight and obesity are estimated at high prevalence and progression in adults; they are major contributors to chronic diseases and a major public health challenge. An obese habitus changes body-surface electrocardiograms (ECGs). Obesity is responsible for geometric changes to the heart and torso, as well as for deleterious electrophysiological changes of the heart. Common ECG changes, reduced voltages in the precordial leads, and axis deviation have made the search for left ventricular hypertrophy (LVH) even more problematic. Identification of LVH by ECG is difficult and time consuming but ECG is fundamental to reveal abnormalities of clinical relevance associated with obesity. The QTc dispersion assessment and the comparison with magnetic resonance imaging are the frontiers to clarify the connection between ECG LVH signs and overweight and obesity. PMID:25091550

    Full Text Available Obesity, along with its related complications, is a serious health problem worldwide. Many studies reported the anti-diabetic effect of phlorizin, while little is known about its anti-obesity effect. We investigated the beneficial effects of phlorizin on obesity and its complications, including diabetes and inflammation in obese animal. Male C57BL/6J mice were divided into three groups and fed their respective experimental diets for 16 weeks: a normal diet (ND, 5% fat, w/w, high-fat diet (HFD, 20% fat, w/w, or HFD supplemented with phlorizin (PH, 0.02%, w/w. The findings revealed that the PH group had significantly decreased visceral and total white adipose tissue (WAT weights, and adipocyte size compared to the HFD. Plasma and hepatic lipids profiles also improved in the PH group. The decreased levels of hepatic lipids in PH were associated with decreased activities of enzymes involved in hepatic lipogenesis, cholesterol synthesis and esterification. The PH also suppressed plasma pro-inflammatory adipokines levels such as leptin, adipsin, tumor necrosis factor-α, monocyte chemoattractant protein-1, interferon-γ, and interleukin-6, and prevented HFD-induced collagen accumulation in the liver and WAT. Furthermore, the PH supplementation also decreased plasma glucose, insulin, glucagon, and homeostasis model assessment of insulin resistance levels. In conclusion, phlorizin is beneficial for preventing diet-induced obesity, hepatic steatosis, inflammation, and fibrosis, as well as insulin resistance.

    The gut microbiome consists of trillions of bacteria which play an important role in human metabolism. Animal and human studies have implicated distortion of the normal microbial balance in obesity and metabolic syndrome. Bacteria causing weight gain are thought to induce the expression of genes related to lipid and carbohydrate metabolism thereby leading to greater energy harvest from the diet. There is a large body of evidence demonstrating that alteration in the proportion of Bacteroidetes and Firmicutes leads to the development of obesity, but this has been recently challenged. It is likely that the influence of gut microbiome on obesity is much more complex than simply an imbalance in the proportion of these phyla of bacteria. Modulation of the gut microbiome through diet, pre- and probiotics, antibiotics, surgery, and fecal transplantation has the potential to majorly impact the obesity epidemic. PMID:27255389

    Full Text Available Today, obesity is a public health problem with significant negative effects on mortality and morbidity rates in developing countries, and impact on all levels of the society. In recent years cognitive behavioral therapy approach has been considered as an important part of the obesity treatment. Behavioral therapy for obesity includes sections like self-monitoring, stimulus control, food control, consolidation and reinforcement, cognitive restructuring, proper nutrition education, increase in physical activity, and behavior contracts. As part of the obesity treatment, combining cognitive-behavioral treatments with lifestyle changes such as increase in physical activity increases effectiveness of the treatment and ensures durability of the achieved weight loss.

    People who are overweight are at increased risk of certain chronic diseases and premature death. However, the physiological consequences are not limited to health symptoms and signs but transcend the social field. In fact, the stigma and discrimination faced by obese people has been proven in multiple areas (work, family, education, etc...). This can contribute to reduce the quality of patients life. From a gender perspective, in the literature there seems to be evidence that the undesirable social effects of obesity affect women more than men. To minimize the obesity impact people adopt proactive methods to lose weight. However the solution to this problem is not on medication but changes in lifestyle and in the proposal of inclusive aesthetic models. Also it is necessary to clear that the complex etiology of obesity can help to reduce the weight stigma and the negative consequences of this condition. PMID:25329415

    The number of older adults living in the USA, 65 years of age and older, has been steadily increasing. Data from the National Health and Nutrition Examination Survey (NHANES), 2007-2010, indicate that more than one-third of older adults, 65 years of age and older, were obese. With the increased rate of obesity in older adults, the purpose of this paper is to present research on different methods to prevent or manage obesity in older adults, namely dietary interventions, physical activity interventions, and a combination of dietary and physical activity interventions. In addition, research on community assistance programs in the prevention of obesity with aging will be discussed. Finally, data on federal programs for older adults will also be presented.

  8. Obesity and colorectal cancer risk

    International Nuclear Information System (INIS)

    Obesity is a chronic and multifactor disease characterized by presence of excess body fat harmful for health. Several studies have been conducted to assess the possible risk character of different factors for colorectal cancer including the following modifying factors: a diet rich in saturated fats, a diet low in vegetables, physical inactivity, alcohol consumption and obesity. A case-control study was conducted to include 276 adult patients (93 cases and 184 controls) consecutively seen from May, 2008 to May, 2009 in the Institute of Gastroenterology determining a possible association between obesity as risk factor and colorectal cancer. Variables measures included: sex, age, skin color, body mass index, hip-waist circumference and endoscopic location of cancer. We conclude that the colorectal cancer with predominance in female sex and in white people in both groups. Obesity according to a great relation hip-waist had an strong relation with colorectal cancer, which had predominance towards distal colon in both sexes

  10. Leptin and Hypertension in Obesity

    OpenAIRE

    Bravo, Paco E; Morse, Stephen; Borne, David M; Aguilar, Erwin A; Reisin, Efrain

    2006-01-01

    Leptin, a peptide discovered more than 10 years ago, decreases food intake and increases sympathetic nerve activity to both thermogenic and nonthermogenic tissue. Leptin was initially believed to be an anti-obesity hormone, owing to its metabolic effects. However, obese individuals, for unknown reasons, become resistant to the satiety and weight-reducing effect of the hormone, but preserve leptin-mediated sympathetic activation to nonthermogenic tissue such as kidney, heart, and adrenal gland...

    Phthalates are commonly used as plasticizers and vehicles for cosmetic ingredients. Phthalate metabolites have documented biochemical activity including activating peroxisome proliferator-activated receptor and antiandrogenic effects, which may contribute to the development of obesity. In vitro and in vivo studies suggest that phthalates have significant effects on the development of obesity, especially after prenatal exposure at low doses. Although few studies have examined the effects of ph...

    2008-01-01

    There is an accumulating amount of evidence indicating that lipid oxidation is depressed in the skeletal muscle of obese individuals. Decrements in fatty acid oxidation (FAO) have been reported with obesity in models ranging from whole body measurements to isolated skeletal muscle preparations as well as in myotubes raised in culture. This reduction appears to be associated with a depression in the activities of enzymes involved in various steps of lipid oxidation, which subsequently partitio...

However, such expenditure needs to be justified in terms of effective...

  17. Obesity and Asthma: Physiological Perspective

    Directory of Open Access Journals (Sweden)

    Bill Brashier

    2013-01-01

    Full Text Available Obesity induces some pertinent physiological changes which are conducive to either development of asthma or cause of poorly controlled asthma state. Obesity related mechanical stress forces induced by abdominal and thoracic fat generate stiffening of the lungs and diaphragmatic movements to result in reduction of resting lung volumes such as functional residual capacity (FRC. Reduced FRC is primarily an outcome of decreased expiratory reserve volume, which pushes the tidal breathing more towards smaller high resistance airways, and consequentially results in expiratory flow limitation during normal breathing in obesity. Reduced FRC also induces plastic alteration in the small collapsible airways, which may generate smooth muscle contraction resulting in increased small airway resistance, which, however, is not picked up by spirometric lung volumes. There is also a possibility that chronically reduced FRC may generate permanent adaptation in the very small airways; therefore, the airway calibres may not change despite weight reduction. Obesity may also induce bronchodilator reversibility and diurnal lung functional variability. Obesity is also associated with airway hyperresponsiveness; however, the mechanism of this is not clear. Thus, obesity has effects on lung function that can generate respiratory distress similar to asthma and may also exaggerate the effects of preexisting asthma.

    The relationship between obesity and other metabolic diseases have been deeply studied. However, there are clinical inconsistencies, exceptions to the paradigm of “more fat means more metabolic disease”, and the subjects in this condition are referred to as metabolically healthy obese (MHO).They have long-standing obesity and morbid obesity but can be considered healthy despite their high degree of obesity. We describe the variable definitions of MHO, the underlying mechanisms that can explain the existence of this phenotype caused by greater adipose tissue inflammation or the different capacity for adipose tissue expansion and functionality apart from other unknown mechanisms. We analyze whether these subjects improve after an intervention (traditional lifestyle recommendations or bariatric surgery) or if they stay healthy as the years pass. MHO is common among the obese population and constitutes a unique subset of characteristics that reduce metabolic and cardiovascular risk factors despite the presence of excessive fat mass. The protective factors that grant a healthier profile to individuals with MHO are being elucidated. PMID:27258304

    The purpose of this article was to compile all existing data regarding the prevalence of obesity in Austria in all age groups, and to perform additional analyses. Prevalence of obesity in the adult Austrian population varies between 8.3 and 19.9% in men, and 9.0 and 19.8% in women with increasing trends over time. Prevalence of obesity in children and adolescents in Austria varies between 3.1 and 9.0% in boys and between 2.2 and 7.3% in girls. Factors associated with obesity include higher age, lower educational level, profession, migration background, living in eastern parts of Austria, lack of social support, and psycho-social pressure. In women, socio-economic parameters are stronger associated with obesity compared to men. Obesity is associated with hypertension, diabetes mellitus, osteoarthritis, and low back pain, and deteriorated quality of live, in both sexes, and in men additionally with a history of heart attack, and in women additionally with anxiety/depression.

    [Purpose] The aim of this study was to identify the effects of obesity on falls as a practical verification of the importance of obesity-targeting interventions as part of future fall prevention programs. [Subjects and Methods] The study involved 351 elderly people (172 men, 179 women) living in rural areas. The dependent variable, fall efficacy, was measured using the Falls Efficacy Scale, while the independent variables, body mass index (BMI) and visceral fat, were measured using the InBody 720. The Faces Pain Scale was used to measure pain. Mobility was measured using the Timed Up and Go Test, and balance ability was measured according to the duration subjects could stand on one foot with their eyes closed. Hierarchical multiple regression analysis was performed for the final data analysis. [Results] Investigation of the correlations between the variables revealed a negative correlation between fall efficacy and the other variables. Ultimatley, investigation of the causality of fall efficacy revealed that the BMI, pain, and mobility were influential factors. In other words, fall efficacy tends to be lower when there are higher degrees of obesity, increased pain, and decreased mobility. [Conclusion] To improve the fall efficacy of elderly people living in rural areas, pain management and the maintenance of physical functionality are required. The present study confirms that the elderly need continuous obesity management to lead healthy lives. PMID:24396217
