    Abstract: Since the previous (1990) edition of this meeting enormous progress in the field of OB associations has been made. Data from X-ray satellites have greatly advanced the study of the low-mass stellar content of associations, while astrometric data from the Hipparcos satellite allow for a characterization of the higher-mass content of associations with unprecedented accuracy. We review recent work on the OB associations located within 1.5 kpc from the Sun, discuss the Hipparcos results...

    Full Text Available We present here a case of 17-year-old boy from Kolkata presenting with obesity, bilateral gynecomastia, mental retardation, and hypogonadotrophic hypogonadism. The patient weighed 70 kg and was of 153 cm height. Facial asymmetry (unilateral facial palsy, gynecomastia, decreased pubic and axillary hair, small penis, decreased right testicular volume, non-palpable left testis, and right-sided congenital inguinal hernia was present. The patient also had disc coloboma, convergent squint, microcornea, microphthalmia, pseudohypertelorism, low set ears, short neck, and choanalatresia. He had h/o VSD repaired with patch. Laboratory examination revealed haemoglobin 9.9 mg/dl, urea 24 mg/dl, creatinine 0.68 mg/dl. IGF1 77.80 ng/ml (decreased for age, GH <0.05 ng/ml, testosterone 0.25 ng/ml, FSH-0.95 ΅IU/ml, LH 0.60 ΅IU/ml. ACTH, 8:00 A.M cortisol, FT3, FT4, TSH, estradiol, DHEA-S, lipid profile, and LFT was within normal limits. Prolactin was elevated at 38.50 ng/ml. The patient′s karyotype was 46XY. Echocardiography revealed ventricularseptal defect closed with patch, grade 1 aortic regurgitation, and ejection fraction 67%. Ultrasound testis showed small right testis within scrotal sac and undescended left testis within left inguinal canal. CT scan paranasal sinuses revealed choanalatresia and deviation of nasal septum to the right. Sonomammography revealed bilateral proliferation of fibroglandular elements predominantly in subareoalar region of breasts. MRI of brain and pituitary region revealed markedly atrophic pituitary gland parenchyma with preserved infundibulum and hypothalamus and widened suprasellar cistern. The CHARGE association is an increasingly recognized non-random pattern of congenital anomalies comprising of coloboma, heart defect, choanal atresia, retarded growth and development, genital hypoplasia, ear abnormalities, and/or deafness. [1] These anomalies have a higher probability of occurring together. In this report, we have

    Brand managers exhibit considerable effort to define intended brand associations to anchor in consumers' minds. They follow a credo deeply rooted in branding literature: intended brand associations drive consumer response and brand equity. This article investigates the benefits of a strong overlap...... of actual consumer brand associations and management-intended brand associations (brand association match). The article presents results from two large-scale studies (3353 and 1201 respondents) involving one consumer goods and one service brand with multiple operationalizations of consumer response...... (attitudinal and behavioral). The results show that consumers with high brand association match show more positive brand response. However, after accounting for the valence of associations match does not add explanatory power. This outcome challenges a key foundation of brand management. The discussion...

    Full Text Available Frequent patterns (itemsets discovery is an important problem in associative classification rule mining.  Differents approaches have been proposed such as the Apriori-like, Frequent Pattern (FP-growth, and Transaction Data Location (Tid-list Intersection algorithm. This paper focuses on surveying and comparing the state of the art associative classification techniques with regards to the rule generation phase of associative classification algorithms.  This phase includes frequent itemsets discovery and rules mining/extracting methods to generate the set of class association rules (CARs.  There are some techniques proposed to improve the rule generation method.  A technique by utilizing the concepts of discriminative power of itemsets can reduce the size of frequent itemset.  It can prune the useless frequent itemsets. The closed frequent itemset concept can be utilized to compress the rules to be compact rules.  This technique may reduce the size of generated rules.  Other technique is in determining the support threshold value of the itemset. Specifying not single but multiple support threshold values with regard to the class label frequencies can give more appropriate support threshold value.  This technique may generate more accurate rules. Alternative technique to generate rule is utilizing the vertical layout to represent dataset.  This method is very effective because it only needs one scan over dataset, compare with other techniques that need multiple scan over dataset.   However, one problem with these approaches is that the initial set of tid-lists may be too large to fit into main memory. It requires more sophisticated techniques to compress the tid-lists.

    2007-01-01

    Background Although molecular pathway information and the International HapMap Project data can help biomedical researchers to investigate the aetiology of complex diseases more effectively, such information is missing or insufficient in current genetic association databases. In addition, only a few of the environmental risk factors are included as gene-environment interactions, and the risk measures of associations are not indexed in any association databases. Description We have developed a published association database (PADB; ) that includes both the genetic associations and the environmental risk factors available in PubMed database. Each genetic risk factor is linked to a molecular pathway database and the HapMap database through human gene symbols identified in the abstracts. And the risk measures such as odds ratios or hazard ratios are extracted automatically from the abstracts when available. Thus, users can review the association data sorted by the risk measures, and genetic associations can be grouped by human genes or molecular pathways. The search results can also be saved to tab-delimited text files for further sorting or analysis. Currently, PADB indexes more than 1,500,000 PubMed abstracts that include 3442 human genes, 461 molecular pathways and about 190,000 risk measures ranging from 0.00001 to 4878.9. Conclusion PADB is a unique online database of published associations that will serve as a novel and powerful resource for reviewing and interpreting huge association data of complex human diseases.

    Full Text Available In hospital-based series viral hepatitis B has been frequently described in association with schistosomiasis whilst in field-based studies the association has not been confirmed. The association between schistosomiasis and Salmonella bacteraemia has been well documented. More recently, acute schistosomiasis has been shown to be a facilitating factor in the genesis of pyogenic liver abscesses caused by Staphylococcus aureus. New evidences indicate an interaction between the acquired immunodeficiency syndrome (AIDS and schistosomiasis. In this paper, data on the association of schistosomiasis with other infections are updated.

    The clinical case of tattoo-associated uveitis was first described by Lubeck and Epstein in 1952. Uveitis is accompanied by induration and hyperemia of tattoo skin, which can precede, follow or manifest simultaneously with uveitis. The diagnosis is determined on clinical grounds after exclusion of other causes. Uveitis is usually bilateral, chronic and vision impairment is variable. Tattoo-associated uveitis should be remembered in differential diagnosis due to the growing interest in tattoo.Key words: uveitis, tattoo, masquerade syndrome.

    Smith, D.J.; Forrest, S. [New Mexico Univ., Albuquerque, NM (United States). Dept. of Computer Science; Perelson, A.S. [Los Alamos National Lab., NM (United States)

    1996-12-31

    The purpose of this paper is to show that immunological memory is an associative and robust memory that belongs to the class of sparse distributed memories. This class of memories derives its associative and robust nature by sparsely sampling the input space and distributing the data among many independent agents. Other members of this class include a model of the cerebellar cortex and Sparse Distributed Memory (SDM). First we present a simplified account of the immune response and immunological memory. Next we present SDM, and then we show the correlations between immunological memory and SDM. Finally, we show how associative recall in the immune response can be both beneficial and detrimental to the fitness of an individual.

  4. [Problems associated with dyslexia].

    Science.gov (United States)

    Artigas-Pallarés, J

    2002-02-01

    In this article we review the disorders of development which affect learning and may be associated with dyslexia. Although the cognitive basis of dyslexia is a phonological deficit, it is not uncommonly associated with other disorders whose deficit is not necessarily related to the dyslexia from a physiopathological point of view. The problems which usually accompany dyslexia are: attention deficit with hyperactivity, dysgraphia, dyscalculia and disorders of the development of coordination. The starting point for understanding this comorbidity is finding broad, dysfunctional areas of the brains of dyslexic patients beyond those theoretically involved in dyslexia. Each of these disorders may or may not occur together with dyslexia. There are even some subtypes which are defined by being associated with dyslexia, leading to the conclusion that in some cases there are underlying common mechanisms. It is necessary to avoid confusion arising over dyslexia due to comorbidity with other conditions.

  5. Chaparral-associated hepatotoxicity.

    Science.gov (United States)

    Sheikh, N M; Philen, R M; Love, L A

    1997-04-28

    Personal health care practices that may include the use of dietary supplements are common in the United States. Products marketed as dietary supplements are diverse and may include botanicals, vitamins, and/or minerals. Chaparral (Larrea tridentata) is a botanical dietary supplement made from a desert shrub and used for its antioxidant properties. Several reports of chaparral-associated hepatitis have been published since 1990, but a complete picture of the clinical presentation is still unclear. We reviewed the 18 case reports of adverse events associated with the ingestion of chaparral reported to the Food and Drug Administration between 1992 and 1994. These reports were from health care professionals, state health departments, and individual consumers. Of 18 reports of illnesses associated with the ingestion of chaparral, there was evidence of hepatotoxicity in 13 cases. Clinical presentation, characterized as jaundice with a marked increase in serum liver chemistry values, occurred 3 to 52 weeks after the ingestion of chaparral, and it resolved 1 to 17 weeks after most individuals stopped their intake of chaparral. The predominant pattern of liver injury was characterized as toxic or drug-induced cholestatic hepatitis; in 4 individuals, there was progression to cirrhosis; and in 2 individuals, there was acute fulminant liver failure that required liver transplants. These data indicate that the use of chaparral may be associated with acute to chronic irreversible liver damage with fulminant hepatic failure, and they underscore the potential for certain dietary supplement ingredients to cause toxic effects on the liver. Health professionals should be encouraged to inquire routinely about the use of dietary supplements and other products, to be alert to potential adverse effects that may be associated with these products, and, finally, to report any serious adverse events associated with these products through the MEDWatch Program of the Food and Drug

    Crowley, R K

    2009-09-30

    BACKGROUND: Acromegaly secondary to growth hormone-releasing hormone (GHRH) excess is rare. AIMS\\/CASE DESCRIPTION: We report two patients with acromegaly who were diagnosed with sellar gangliocytomas that were immunopositive for GHRH. Tumour tissue persisted after debulking surgery and in the second case this was associated with persistent growth hormone hypersecretion, successfully suppressed by a somatostatin analogue. CONCLUSIONS: The development of functional pituitary adenomas in association with sellar gangliocytomas is poorly understood. We present a brief discussion of the possible aetiology of these unusual pituitary tumours.

    Data are presented for ten women with anovulation, nine of them with amenorrhea, who have associated carotenemia. Classic explanations for carotenemia in amenorrheic patients have been weight loss or anorexia nervosa, yet carotenemia in our patients appeared to be diet induced. All patients consumed a pure or predominantly vegetarian diet; there was no intake of red meats. Clinical and laboratory data of the patients are presented. The amenorrhea of the patient is consistent with hypothalamic hypogonadotropic anovulation (HHA). It appeared that diet modification not only led to reduction in carotene levels, but also improved the menstrual status. The association of carotenemia and menstrual disorders is reviewed. The possibility that carotenemia is related to the development of HHA is discussed.

  20. Ontology in association rules.

    Data mining has emerged to address the problem of transforming data into useful knowledge. Although most data mining techniques, such as the use of association rules, may substantially reduce the search effort over large data sets, often, the consequential outcomes surpass the amount of information humanly manageable. On the other hand, important association rules may be overlooked owing to the setting of the support threshold, which is a very subjective metric, but rooted in most data mining techniques. This paper presents a study on the effects, in terms of precision and recall, of using a data preparation technique, called SemPrune, which is built on domain ontology. SemPrune is intended for pre- and post-processing phases of data mining. Identifying generalization/specialization relations, as well as composition/decomposition relations, is the key to successfully applying SemPrune.

    2012-12-28

    We introduce a bipartite, diluted and frustrated, network as a sparse restricted Boltzmann machine and we show its thermodynamical equivalence to an associative working memory able to retrieve several patterns in parallel without falling into spurious states typical of classical neural networks. We focus on systems processing in parallel a finite (up to logarithmic growth in the volume) amount of patterns, mirroring the low-level storage of standard Amit-Gutfreund-Sompolinsky theory. Results obtained through statistical mechanics, the signal-to-noise technique, and Monte Carlo simulations are overall in perfect agreement and carry interesting biological insights. Indeed, these associative networks pave new perspectives in the understanding of multitasking features expressed by complex systems, e.g., neural and immune networks.

    The sharing of association rules is often beneficial in industry, but requires privacy safeguards. One may decide to disclose only part of the knowledge and conceal strategic patterns which we call restrictive rules. These restrictive rules must be protected before sharing since they are paramount for strategic decisions and need to remain private. To address this challenging problem, we propose a unified framework for protecting sensitive knowledge before sharing. This framework encompasses:...

    Full Text Available Introduction: The differential diagnosis of idiopathic and syringomyelia associated scoliosis is important because corrective surgery for scoliosis associated with syringomyelia prior to management of syringomyelia can be dangerous. There are important imaging indicators for diagnosis of syringomyelia associated with scoliosis. A few of these indicators have been assessed in our study. Methods: A retrospective descriptive study including 38 patients with both scoliosis and syringomyelia was performed at the Shafa Yahyaeian center. Standard scoliosis series radiographs and MRI of all patients were studied. The type of scoliosis, location and magnitude of deformity, kyphosis or lordosis in the sagittal plane, location and size of syrinx were assessed. Results: Thoracic kyphosis was present in 94.7% of patients. 37% of patients had scoliosis with convexity to left. Arnold –chiari malformation was present in 36% and cord tethering in 21% of patients. The locations of syrinx were as follows: 47.4%cervical, 44.6 thoracic, 2.7% lumbar and 5.3% were holocord. Conclusion: Kyphosis, abscence of lordosis in sagittal plane, progressive scoliosis and scoliosis with convexity to left are atypical findings and could be indicators of the presence of syringomyelia. If these indicators are present, a diagnosis of idiopathic scoliosis should be made with caution.

    Background Edema associated with quetiapine has been described in only one case report to date and represents a potentially serious adverse reaction. Methods We present a case series of three patients who developed bilateral leg edema following initiation of quetiapine. Results One of these patients had a recurrence of edema with subsequent rechallenge. Another patient developed quetiapine-induced edema following a prior episode of olanzapine-induced edema. All the cases present a compelling temporal relationship between the drug challenge and the adverse event. Conclusions Prompt recognition and intervention with discontinuation of the offending agent is important for this potentially serious, seemingly idiosyncratic, vascular complication. PMID:19439156

    The fourth case in the literature is presented of a patient with the rare association of hyperparathyroidism and osteosarcoma. A 56-year-old woman presented with hyperparathyroidism and a lesion in the tibia. Initial diagnosis was brown tumor. Histology, however, revealed osteosarcoma, and the patient was treated accordingly. The experimental induction of osteosarcoma by parathormone in rodent studies makes this finding alarming, considering the increasing use of parathormone in the treatment of osteoporosis. The mechanism by which osteosarcoma is induced in humans cannot be explained based on current knowledge of mechanisms of action of parathyroid hormone. (orig.)

    Poppers are a common drug belonging to the alkyl nitrite group and in use for several decades. They can be legally purchased for air freshening, but are illegal to buy for inhalation. Abuse is associated with maculopathy and visual loss as a rare side effect. A case series of 27 male, homosexual patients with poppers abuse presenting to a single eye clinic in Berlin, Germany, is described. Four patients with visual impairment and maculopathy associated with the inhalation of poppers were found. Four patients experienced subacute visual loss over 2-6 months, one patient can no longer read without a magnifying glass. The median age is 40.25 years (28-45 years). Three patients are HIV-positive (known since 10-22 years, HAART), a patient is also hepatitis C-positive. No other ocular and systemic diseases are known. Poppers have been inhaled for about 1.5, 12, 15 and 25 years (3-4 ×/week); all patients have a mixed use with the brands Jungle Juice, Rush and Amsterdam. Three patients noticed a simultaneous change in colour and shade. Clinical signs on fundoscopy ranged from normal foveal appearance to yellowish, dull macula. Optical coherence tomography (HD-OCT) showed varying degrees of disruption of the presumed inner segment/outer segment (IS/OS) junction; 3 cases bilaterally symmetrical. Although poppers have been in use for several decades, in 2007 in England, the popper composition was changed by law from isobutyl nitrite to isopropyl nitrite. It is hard to distinguish whether a specific nitrite group triggers the maculopathy or whether it is the dose level, thus suggesting the existence of a cumulative dose-response relationship. We postulate that a major factor of the manifestation of maculopathy is the individual limit of vulnerability. Despite decades of use, the majority of our series does not present any pathology. Limits of our patient population represents the HIV disease: three maculopathies of our series are HIV-associated and controlled by

    Circumscribed scleroderma or morphea is a rare disease that involves limited areas of skin and usually is not associated with visceral lesions. Its etiology is still debated, but its appearance signifies a particular immunological status. We present a case of a male patient, which developed morphea lesions during the infection with Toxoplasma gondii. Clinical manifestation was characteristic for the classic plaque-type of morphea. Diagnosis was confirmed by the histopathologic examine of the cutaneous lesions. The evolution of lesions was correlated with antibodies titre for Toxoplasma gondii, and local administration of corticosteroids accelerated the evolution to cutaneous lesions stabilization.

    2015-01-01

    This work reviews research on neural mechanisms of two types of associative learning in the marine mollusk Aplysia, classical conditioning of the gill- and siphon-withdrawal reflex and operant conditioning of feeding behavior. Basic classical conditioning is caused in part by activity-dependent facilitation at sensory neuron–motor neuron (SN–MN) synapses and involves a hybrid combination of activity-dependent presynaptic facilitation and Hebbian potentiation, which are coordinated by trans-synaptic signaling. Classical conditioning also shows several higher-order features, which might be explained by the known circuit connections in Aplysia. Operant conditioning is caused in part by a different type of mechanism, an intrinsic increase in excitability of an identified neuron in the central pattern generator (CPG) for feeding. However, for both classical and operant conditioning, adenylyl cyclase is a molecular site of convergence of the two signals that are associated. Learning in other invertebrate preparations also involves many of the same mechanisms, which may contribute to learning in vertebrates as well. PMID:25877219

    Full Text Available Bloody pleural effusion is rarely associated with endometriosis. To effectively treat this condition, it is important to differentiate the malady from other common diseases such as malignancy or tuberculosis. We describe the case of a 40-year-old multiparous female featuring right-sided hemothorax presenting with right shoulder pain and progressive shortness of breath for the preceding 2 months. Thoracoscopy disclosed grossly negative findings apart from multiple small pores in the right hemi-diaphragm with blood clots within them. Examination of the thoracoscopic biopsy specimens showed chronic pleuritis without evidence of malignancy or tuberculosis. Pelvic endometriosis was considered a possible diagnosis according to the results of abdominal computed tomography (CT scan, transvaginal sonography, and the results of dilatation and curettage. Periodic episodes of symptoms concurrent with menstruation led to the suspicion of a relationship between these conditions in our patient. Despite the patient undergoing an abdominal total hysterectomy and adhesiolysis without salpingo-oophorectomy, recurrent right-sided bloody pleural effusion developed 1.5 months subsequent to surgery. As a consequence, danazol (400 mg/day was maintained because of the endometriosis associated with pleural effusion. One year of regular follow-up later, there was no evidence of recurrent pleural effusion. We considered that the bloody pleural fluid arose via seepage from the pelvic endometriosis through the pores of the right hemi-diaphragm during menstruation.

    Chalazion may be associated with some local and systemic conditions. We studied the prevalence of various conditions among patients with chalazion. A retrospective observational case-control study of all the members who were diagnosed with chalazion in the Central District of Clalit Health Services in Israel (years 2000-2008; n = 9119) and 9119 age- and gender-matched controls randomly selected from the district members. We calculated the prevalence of various ocular, systemic, and demographic conditions as risk factors for chalazion. Demographically, a significant (P chalazion was found in the population of lower socioeconomic class, in the population living in urban areas, in young females (10-29 years), in older men (older than 60 years), and in non-Ashkenazi Jews. The following risk factors of chalazion were statistically significant: blepharitis [odds ratio (OR), 6.2], rosacea (OR, 2.9), gastritis (OR, 1.4), anxiety (OR, 1.5), irritable bowel syndrome (OR, 1.7), and smoking (OR, 1.2). Diabetes (OR, 0.8) and hypothyroidism (OR, 0.8) were significantly less prevalent among chalazion patients. Some systemic conditions are significantly more prevalent and some are significantly less prevalent among patients with chalazion. Better understanding of the pathophysiological association between those diseases and chalazion may help in its treatment and prevention.

    1998-01-01

    AIM—Preseptal and orbital cellulitis are rare presenting features of intraocular retinoblastoma. The objectives of this study were to determine the frequency of retinoblastoma associated cellulitis, as well as to review its clinical and histopathological features.
METHODS—The medical records of 292 retinoblastoma patients in the King Khaled Eye Specialist Hospital in Riyadh, Saudi Arabia were reviewed. Those indicating a history of, or presenting with, cellulitis were retrieved and their clinical, radiological, and histopathological variables were assessed. Patients with definite extraocular tumour extension on clinical or radiological examination were excluded.
RESULTS—14 patients were found to have retinoblastoma associated cellulitis (4.8%); nine had bilateral and five had unilateral retinoblastoma. Conjunctival and blood cultures were performed in 10 cases and were negative. 10 children were treated with intravenous steroids, often in conjunction with antibiotics, resulting in a prompt decrease in inflammation. Three other children were treated with antibiotics alone and one received no treatment. Computed tomographic scanning depicted large intraocular tumours occupying between 80% and 100% of the globe in each case. In eight patients, periocular inflammation was radiologically interpreted as possible extraocular extension. In one patient serial computed tomographic scanning showed a reduction in intraocular calcification over time which occurred in the presence of cellulitis. 12 patients underwent enucleation and histopathological examination revealed large necrotic, poorly differentiated tumours associated with uveal involvement and early optic nerve invasion. Focal perilimbal destruction was seen in one patient, and in another peripapillary extrascleral extension was present. 12 patients are alive with a mean follow up of 56.4 months.
CONCLUSIONS—Radiological evaluation of scleral integrity may be hindered by periocular inflammatory

    Full Text Available The intersecting HIV and Tuberculosis epidemics in countries with a high disease burden of both infections pose many challenges and opportunities. For patients infected with HIV in high TB burden countries, the diagnosis of TB, ARV drug choices in treating HIV-TB coinfected patients, when to initiate ARV treatment in relation to TB treatment, managing immune reconstitution, minimising risk of getting infected with TB and/or managing recurrent TB, minimizing airborne transmission, and infection control are key issues. In addition, given the disproportionate burden of HIV in women in these settings, sexual reproductive health issues and particular high mortality rates associated with TB during pregnancy are important. The scaleup and resource allocation to access antiretroviral treatment in these high HIV and TB settings provide a unique opportunity to strengthen both services and impact positively in meeting Millennium Development Goal 6.

    To report several cases of hyperthyroidism in patients presenting with the unusual symptom of sleepwalking and to discuss the possible pathophysiologic basis for this novel association. After encountering and reporting the first case of new-onset somnambulism in a patient presenting with thyrotoxicosis at our institution, we routinely inquired about the sleep history of patients with thyrotoxicosis, questioning both the patients and family members when applicable. Those patients who actually had sleepwalking episodes coinciding with the onset of thyrotoxicosis underwent close follow-up, and the relationship between the sleepwalking and the results of thyroid function tests was analyzed. In addition, we reviewed the literature on psychiatric disorders and sleep problems, and the pathophysiologic rationale for a cause-and-effect relationship is discussed. We collected 8 cases of patients with new-onset sleepwalking episodes that coincided with the start of thyrotoxicosis. The disappearance of the sleepwalking with successful achievement of euthyroidism supports a cause-and-effect relationship. This hypothesis is further supported by the absence of a family history, the adult onset, and the relapse of sleepwalking in 2 of the patients when their thyrotoxicosis became poorly controlled as a result of noncompliance with medications and its subsequent disappearance with reachievement of euthyroidism. Of note, such a presentation was seen only in patients with thyrotoxicosis caused by diffuse toxic goiter or Graves' disease and never in patients with other causes of thyrotoxicosis. New-onset sleepwalking could be caused by thyrotoxicosis or, more specifically, by thyrotoxicosis resulting from diffuse toxic goiter. The mechanism is hypothesized to be related to the combination of prolongation of non-rapid eye movement sleep and the associated fatigue. Specific inquiry about this unusual presentation of thyrotoxicosis is encouraged, and more studies are needed to confirm

  5. Vaccine-associated hypersensitivity.

    McNeil, Michael M; DeStefano, Frank

    2018-02-01

    Vaccine-associated hypersensitivity reactions are not infrequent; however, serious acute-onset, presumably IgE-mediated or IgG and complement-mediated anaphylactic or serious delayed-onset T cell-mediated systemic reactions are considered extremely rare. Hypersensitivity can occur because of either the active vaccine component (antigen) or one of the other components. Postvaccination acute-onset hypersensitivity reactions include self-limited localized adverse events and, rarely, systemic reactions ranging from urticaria/angioedema to full-blown anaphylaxis with multisystem involvement. Risk of anaphylaxis after all vaccines is estimated to be 1.31 (95% CI, 0.90-1.84) per million vaccine doses, respectively. Serious hypersensitivity reactions after influenza vaccines are particularly important because of the large number of persons vaccinated annually. Influenza vaccines are unique in requiring annual changes in the vaccines' antigenic composition to match the predicted circulating influenza strains. Recently, novel influenza vaccine types were introduced in the United States (recombinant vaccines, some with higher antigen content and a new adjuvanted vaccine). Providers should be aware of changing recommendations on the basis of recent published evidence for persons with a history of egg allergy to receive annual influenza vaccination. Further research is needed to elucidate the pathophysiology and risk factors for reported vaccine-associated adverse events. Further research is also needed to determine whether repeated annual inactivated influenza vaccination, the number of vaccine antigens administered at the same time, and the current timing of routine infant vaccinations are optimal for overall population well-being.

  6. Does the standard voluntary association question capture informal associations?

    Science.gov (United States)

    Paxton, Pamela; Rap, Robyn

    2016-11-01

    Sociologists have long been attentive to participation in associational life. Yet, despite being repeatedly cautioned to consider more informal groups, most researchers focus on participation in formal voluntary associations using national surveys with fixed group categories, such as the General Social Survey (GSS). In this paper, we use new GSS data on the names of the voluntary associations listed by respondents to evaluate whether voluntary association prompts capture or miss various types of informal associations. We code the formality of the associations listed by respondents and also compare to a new sample of bottom-up, informal voluntary associations. We demonstrate that some response categories adequately capture both formal and informal associations, e.g., sports groups. However, our results also suggest that the standard voluntary association question both omits entire categories of informal associations and omits some informal variants of associations within categories. In the tradition of Baumgartner and Walker (1988), Wuthnow (1994), and Wellman et al. (2001), we suggest that we may misunderstand citizen associations if we ignore informal associating.

  7. Non-associative versus associative learning by foraging predatory mites.

    Schausberger, Peter; Peneder, Stefan

    2017-01-14

    Learning processes can be broadly categorized into associative and non-associative. Associative learning occurs through the pairing of two previously unrelated stimuli, whereas non-associative learning occurs in response to a single stimulus. How these two principal processes compare in the same learning task and how they contribute to the overall behavioural changes brought about by experience is poorly understood. We tackled this issue by scrutinizing associative and non-associative learning of prey, Western flower thrips Frankliniella occidentalis, by the predatory mite, Neoseiulus californicus. We compared the behaviour of thrips-experienced and -naïve predators, which, early in life, were exposed to either thrips with feeding (associative learning), thrips without feeding (non-associative learning), thrips traces on the surface (non-associative learning), spider mites with feeding (thrips-naïve) or spider mite traces on the surface (thrips-naïve). Thrips experience in early life, no matter whether associative or not, resulted in higher predation rates on thrips by adult females. In the no-choice experiment, associative thrips experience increased the predation rate on the first day, but shortened the longevity of food-stressed predators, a cost of learning. In the choice experiment, thrips experience, no matter whether associative or not, increased egg production, an adaptive benefit of learning. Our study shows that both non-associative and associative learning forms operate in foraging predatory mites, N. californicus. The non-rewarded thrips prey experience produced a slightly weaker, but less costly, learning effect than the rewarded experience. We argue that in foraging predatory mites non-associative learning is an inevitable component of associative learning, rather than a separate process.

  8. Simulated Associating Polymer Networks

    Science.gov (United States)

    Billen, Joris

    Telechelic associating polymer networks consist of polymer chains terminated by endgroups that have a different chemical composition than the polymer backbone. When dissolved in a solution, the endgroups cluster together to form aggregates. At low temperature, a strongly connected reversible network is formed and the system behaves like a gel. Telechelic networks are of interest since they are representative for biopolymer networks (e.g. F-actin) and are widely used in medical applications (e.g. hydrogels for tissue engineering, wound dressings) and consumer products (e.g. contact lenses, paint thickeners). In this thesis such systems are studied by means of a molecular dynamics/Monte Carlo simulation. At first, the system in rest is studied by means of graph theory. The changes in network topology upon cooling to the gel state, are characterized. Hereto an extensive study of the eigenvalue spectrum of the gel network is performed. As a result, an in-depth investigation of the eigenvalue spectra for spatial ER, scale-free, and small-world networks is carried out. Next, the gel under the application of a constant shear is studied, with a focus on shear banding and the changes in topology under shear. Finally, the relation between the gel transition and percolation is discussed.

    Full Text Available Objective: To analyze the characteristics of children with central precocious puberty (CPP, identifying both their clinical and epidemiological characteristics, as well as the determinants for receiving timely specialized health care. Methods: Cross-sectional retrospective study with analytical approach of 342 medical records of children aged 1 to 11 years with CPP, from the Endocrinology Outpatient Clinic of a reference hospital. Biological, socio-economic, family and nutritional data of the 1994 to 2010 period was submitted to univariate and bivariate analysis, using the chi-square test for the statistical evaluation of the associations. Results: The main features of children with CPP were: being adopted, 25 (7.3%; being overweight, 92 (27.1%; being obese, 85 (25.1%; initiating puberty before six years of age, 205 (60.3%. Children with PPC who received late specialized care were the ones who most precociously presented signs of puberty (p<0.001, and belonged to families with lower income (p<0.002. Conclusion: High proportions of children with CPP were adopted and presented overweight/obesity. Children with excessively early onset of puberty signs, and belonging to low income families, suffered significant delay in obtaining specialized care. doi:10.5020/18061230.2014.p153

    2010-04-01

    Pruritus is commonly associated with cholestatic disorders and shows wide interindividual variability. The presence of skin lesions due to scratching and the application of a visual analogue scale are useful for clinical evaluation. Although the pathophysiology of this entity is not well understood, advances have recently been made in understanding of the pruritoceptive neural pathway, which shares certain similarities with the nociceptive pathway, although there are other distinguishing characteristics such as the action of a specific neurotransmitter, GPR, on the first synapsis at the posterior horn of the spinal cord. Amongst the modulator systems of the pruritoceptive pathway is the action of the endogenous opioids. An increase of these opioids in cholestatic situations is the most widely accepted hypothesis for pruritus in these patients. Some treatments have proven efficacy in randomized clinical trials in patients with cholestatic disorders, such as anion exchange resins, rifampicin, opioid antagonists and ursodeoxycholic acid; the latter is especially useful in intrahepatic cholestasis of pregnancy.

  11. Attentive multidirectional associative memory with application to pattern association

    Tai, Heng-Ming

    1992-07-01

    An attentive multidirectional hetero-associative memory network (AMAM) is proposed. The convergence and encoding strategies of AMAM are described. This network enables multiple associations, but with certain associations embedding more attention. This model is inspired by speculation about how associative learning and storage might occur in the nervous system. AMAM has much better error correcting capability and memory capacity than the multidirectional associative memory. Examples are illustrated to show the advantages of this model. In addition, we demonstrate and compare its recall ability for pattern recognition.

    Associative learning plays a variety of roles in the study of animal cognition from a core theoretical component to a null hypothesis against which the contribution of cognitive processes is assessed. Two developments in contemporary associative learning have enhanced its relevance to animal cognition. The first concerns the role of associatively activated representations, whereas the second is the development of hybrid theories in which learning is determined by prediction errors, both directly and indirectly through associability processes. However, it remains unclear whether these developments allow associative theory to capture the psychological rationality of cognition. I argue that embodying associative processes within specific processing architectures provides mechanisms that can mediate psychological rationality and illustrate such embodiment by discussing the relationship between practical reasoning and the associative-cybernetic model of goal-directed action.

    Recent studies have shown altered cortical plasticity in adult patients with Tourette syndrome. However, the clinical significance of this finding remains elusive. Motor cortical plasticity was evaluated in 15 adult patients with severe Tourette syndrome and 16 healthy controls using the paired associative stimulation protocol by transcranial magnetic stimulation. Associations between paired associative stimulation-induced plasticity and relevant clinical variables, including cortical excitability, psychiatric comorbidities, drug treatment and tic severity, were assessed. Motor cortical plasticity was abnormally increased in patients with Tourette syndrome compared with healthy subjects. This abnormal plasticity was independently associated with tic severity. Patients with severe Tourette syndrome display abnormally increased cortical associative plasticity. This aberrant cortical plasticity was associated with tic severity, suggesting an underlying mechanism for tic pathophysiology. © 2015 International Parkinson and Movement Disorder Society.

    2017-03-01

    Interest in the metabolic syndrome-associated osteoarthritis phenotype is increasing. Here, we summarize recently published significant findings. Meta-analyses confirmed an association between type 2 diabetes and osteoarthritis and between cardiovascular diseases and osteoarthritis. Recent advances in the study of metabolic syndrome-associated osteoarthritis have focused on a better understanding of the role of metabolic diseases in inducing or aggravating joint damage. In-vivo models of obesity, diabetes, or dyslipidemia have helped to better decipher this association. They give emerging evidence that, beyond the role of common pathogenic mechanisms for metabolic diseases and osteoarthritis (i.e., low-grade inflammation and oxidative stress), metabolic diseases have a direct systemic effect on joints. In addition to the impact of weight, obesity-associated inflammation is associated with osteoarthritis severity and may modulate osteoarthritis progression in mouse models. As well, osteoarthritis synovium from type 2 diabetic patients shows insulin-resistant features, which may participate in joint catabolism. Finally, exciting data are emerging on the association of gut microbiota and circadian rhythm and metabolic syndrome-associated osteoarthritis. The systemic role of metabolic syndrome in osteoarthritis pathophysiology is now better understood, but new avenues of research are being pursued to better decipher the metabolic syndrome-associated osteoarthritis phenotype.

    Non-commutativity and non-associativity are quite natural in string theory. For open strings it appears due to the presence of non-vanishing background two-form in the world volume of Dirichlet brane, while in closed string theory the flux compactifications with non-vanishing three-form also lead to non-geometric backgrounds. In this paper, working in the framework of deformation quantization, we study the violation of associativity imposing the condition that the associator of three elements should vanish whenever each two of them are equal. The corresponding star products are called alternative and satisfy important for physical applications properties like the Moufang identities, alternative identities, Artin's theorem, etc. The condition of alternativity is invariant under the gauge transformations, just like it happens in the associative case. The price to pay is the restriction on the non-associative algebra which can be represented by the alternative star product, it should satisfy the Malcev identity. The example of nontrivial Malcev algebra is the algebra of imaginary octonions. For this case we construct an explicit expression of the non-associative and alternative star product. We also discuss the quantization of Malcev–Poisson algebras of general form, study its properties and provide the lower order expression for the alternative star product. To conclude we define the integration on the algebra of the alternative star products and show that the integrated associator vanishes.

    Kandinsky proposed a correspondence theory that suggests associations between specific colors and shapes (i.e., circle-blue, square-red, triangle-yellow). Makin and Wuerger tested the theory using the Implicit Association Test (IAT) and did not find clear evidence for Kandinsky's color-shape associations among British participants. In the present study, we first replicated the previous study among Japanese participants and found similar results to those of Makin and Wuerger, showing little support for Kandinsky's theory. In the subsequent experiment, we tested another set of color-shape associations that had been revealed by using an explicit matching method (circle-red, square-blue, triangle-yellow) in Japanese participants. The IAT tests showed that response times were significantly faster when circle-red, square-blue, and triangle-yellow combinations were mapped onto the same response key, rather than different key combinations, indicating that these color-shape combinations were encoded. These results provide the first empirical evidence that color-shape associations can be measured by indirect behavioral methods, and in particular, Japanese people's color-shape associations (circle-red, square-blue, triangle-yellow) can be observed by both direct and indirect experimental methods.

    Faces provide important characteristics of a person"s identification. In security checks, face recognition still remains the method in continuous use despite other approaches (i.e. fingerprints, voice recognition, pupil contraction, DNA scanners). With an associative memory, the output data is recalled directly using the input data. This can be achieved with a Nonlinear Holographic Associative Memory (NHAM). This approach can also distinguish between strongly correlated images and images that are partially or totally enclosed by others. Adaptive wavelet lifting has been used for Content-Based Image Retrieval. In this paper, adaptive wavelet lifting will be applied to face recognition to achieve an associative memory.

  11. Association of prediabetes-associated single nucleotide polymorphisms with microalbuminuria.

    Full Text Available Increased glycemic exposure, even below the diagnostic criteria for diabetes mellitus, is crucial in the pathogenesis of diabetic microvascular complications represented by microalbuminuria. Nonetheless, there is limited evidence regarding which single nucleotide polymorphisms (SNPs are associated with prediabetes and whether genetic predisposition to prediabetes is related to microalbuminuria, especially in the general population. Our objective was to answer these questions. We conducted a genomewide association study (GWAS separately on two population-based cohorts, Ansung and Ansan, in the Korean Genome and Epidemiology Study (KoGES. The initial GWAS was carried out on the Ansung cohort, followed by a replication study on the Ansan cohort. A total of 5682 native Korean participants without a significant medical illness were classified into either control group (n = 3153 or prediabetic group (n = 2529. In the GWAS, we identified two susceptibility loci associated with prediabetes, one at 17p15.3-p15.1 in the GCK gene and another at 7p15.1 in YKT6. When variations in GCK and YKT6 were used as a model of prediabetes, this genetically determined prediabetes increased microalbuminuria. Multiple logistic regression analyses revealed that fasting glucose concentration in plasma and SNP rs2908289 in GCK were associated with microalbuminuria, and adjustment for age, gender, smoking history, systolic blood pressure, waist circumference, and serum triglyceride levels did not attenuate this association. Our results suggest that prediabetes and the associated SNPs may predispose to microalbuminuria before the diagnosis of diabetes mellitus. Further studies are needed to explore the details of the physiological and molecular mechanisms underlying this genetic association.

  14. Partial monoids: associativity and confluence

    Poinsot, Laurent; Tollu, Christophe

    2010-01-01

    A partial monoid $P$ is a set with a partial multiplication $\\times$ (and total identity $1_P$) which satisfies some associativity axiom. The partial monoid $P$ may be embedded in a free monoid $P^*$ and the product $\\star$ is simulated by a string rewriting system on $P^*$ that consists in evaluating the concatenation of two letters as a product in $P$, when it is defined, and a letter $1_P$ as the empty word $\\epsilon$. In this paper we study the profound relations between confluence for such a system and associativity of the multiplication. Moreover we develop a reduction strategy to ensure confluence and which allows us to define a multiplication on normal forms associative up to a given congruence of $P^*$. Finally we show that this operation is associative if, and only if, the rewriting system under consideration is confluent.

    CERN Document Server

    Rauch, Jan

    2013-01-01

    Observational calculi were introduced in the 1960’s as a tool of logic of discovery. Formulas of observational calculi correspond to assertions on analysed data. Truthfulness of suitable assertions can lead to acceptance of new scientific hypotheses. The general goal was to automate the process of discovery of scientific knowledge using mathematical logic and statistics. The GUHA method for producing true formulas of observational calculi relevant to the given problem of scientific discovery was developed. Theoretically interesting and practically important results on observational calculi were achieved. Special attention was paid to formulas - couples of Boolean attributes derived from columns of the analysed data matrix. Association rules introduced in the 1990’s can be seen as a special case of such formulas. New results on logical calculi and association rules were achieved. They can be seen as a logic of association rules. This can contribute to solving contemporary challenging problems of data minin...

    There is growing demand for new bioactive compounds and biologicals for the pharmaceutical, agro- and food industries. Plant-associated microbes present an attractive and promising source to this end, but are nearly unexploited. Therefore, bioprospecting of plant microbiomes is gaining more and more attention. Due to their highly specialized and co-evolved genetic pool, plant microbiomes host a rich secondary metabolism. This article highlights the potential detection and use of secondary metabolites and enzymes derived from plant-associated microorganisms in biotechnology. As an example we summarize the findings from the moss microbiome with special focus on the genus Sphagnum and its biotechnological potential for the discovery of novel microorganisms and bioactive molecules. The selected examples illustrate unique and yet untapped properties of plant-associated microbiomes, which are an immense treasure box for future research. Copyright © 2016 Elsevier B.V.

    Lotrich, Francis E

    2015-08-18

    Inflammatory cytokines can sometimes trigger depression in humans, are often associated with depression, and can elicit some behaviors in animals that are homologous to major depression. Moreover, these cytokines can affect monoaminergic and glutamatergic systems, supporting an overlapping pathoetiology with major depression. This suggests that there could be a specific major depression subtype, inflammatory cytokine-associated depression (ICAD), which may require different therapeutic approaches. However, most people do not develop depression, even when exposed to sustained elevations in inflammatory cytokines. Thus several vulnerabilities and sources of resilience to inflammation-associated depression have been identified. These range from genetic differences in neurotrophic and serotonergic systems to sleep quality and omega-3 fatty acid levels. Replicating these sources of resilience as treatments could be one approach for preventing "ICAD". This article is part of a Special Issue entitled SI: Neuroimmunology in Health And Disease.

    2009-01-01

    Increased technological complexity of medical devices and systems coupled with increased workloads and reduced staffing, have created difficulties and discontinuities in the management of patient information. These issues have directly impacted and contributed to a rise in equipment-related errors, patient dissatisfaction, a potential for patient injury and resulting overall increased concern for patient safety. In response these concerns a variety of new devices, systems and applications have been developed to share information, provide cross checks along with verified delivery of critical information to the point of care. These applications include biomedical information systems, medication administration, sample collection, and electronic medical records. The deployment of these new integrated and networked devices, systems and applications are dependent on an accurate and consistent patient identification and association methodology which dynamically manages the relationship between patients, staff and equipment. Since the association information is common to many applications and utilizes a variety of technologies, (i.e. active and passive radio frequency identification (RFID), barcodes, etc.) an institutional approach is necessary to mange these processes in a consistent manor utilizing a common set of identification hardware. Implementation of a "Patient Centric Identification and Association Platform" represents a significant advance in the management of clinical patient information. The implementation of a Biomedical Device Information Network at Memorial Sloan-Kettering Cancer Center (MSKCC) integrates the identification and association of patients with devices and care providers and provides the methodologies to manage alarms, providing the ability to filter low priority or nuisance alarms. This implementation enables critical information to be distributed directly to care providers utilizing dedicated communications devices. Patient Centric

    Breast cancer is one of the most common malignancies affecting pregnancy. Pregnancy-associated breast cancer refers to breast cancer that is diagnosed during pregnancy or within the first postpartum year. The incidence is increasing as more women delay childbearing. Breast cancer can be safely diagnosed, staged, and treated during pregnancy while protecting the fetus and mother with excellent outcomes for both. Avoiding diagnostic delays is vital to prognosis. This article provides an overview of the diagnosis, staging, management, and prognosis of pregnancy-associated breast cancer. Relevant current literature is reviewed.

    2016-05-24

    Hydroxy-methyl-glutaryl-coenzyme A (HMG-CoA) reductase inhibitors or statins are well tolerated, but associated with various statin-associated symptoms (SAS), including statin-associated muscle symptoms (SAMS), diabetes mellitus (DM), and central nervous system complaints. These are "statin-associated symptoms" because they are rare in clinical trials, making their causative relationship to statins unclear. SAS are, nevertheless, important because they prompt dose reduction or discontinuation of these life-saving mediations. SAMS is the most frequent SAS, and mild myalgia may affect 5% to 10% of statin users. Clinically important muscle symptoms, including rhabdomyolysis and statin-induced necrotizing autoimmune myopathy (SINAM), are rare. Antibodies against HMG-CoA reductase apparently provoke SINAM. Good evidence links statins to DM, but evidence linking statins to other SAS is largely anecdotal. Management of SAS requires making the possible diagnosis, altering or discontinuing the statin treatment, and using alternative lipid-lowering therapy.

  7. Family planning associations support themselves.

    Science.gov (United States)

    Kunii, C

    1988-12-01

    The major sources of funding for family planning associations include: 1) contributions from foundations and private individuals; 2) government subsidies; 3) international assistance; and 4) profits from family planning services, e.g., contraceptive sales, operation of family planning clinics and health check laboratories, and sales of educational materials. In many Asian countries, the operation of health check laboratories appears to be an especially promising source of income. Industrialization and higher education have produced an increased emphasis on good health and a higher quality of life. Family planning associations can thus play a role in providing regular health check-ups and health education for all family members. Family planning counseling can be provided to clients as a part of their medical check-ups. Since such examinations should be conducted on a yearly basis, a fixed amount of income can be assumed. Family planning associations that are considering starting a health examination program should invest in the necessary facilities and equipment, recruit medical doctors and laboratory technicians, and form linkages with specialists, hospitals, universities, and other research institutions. It may take 3-5 years for a family planning association to accumulate the necessary technology and experience in this field and to acquire the confidence of the general public.

  13. Chromosomal Abnormalities Associated With Omphalocele

    Directory of Open Access Journals (Sweden)

    Chih-Ping Chen

    2007-03-01

    Full Text Available Fetuses with omphalocele have an increased risk for chromosomal abnormalities. The risk varies with maternal age, gestational age at diagnosis, association with umbilical cord cysts, complexity of associated anomalies, and the contents of omphalocele. There is considerable evidence that genetics contributes to the etiology of omphalocele. This article provides an overview of chromosomal abnormalities associated with omphalocele and a comprehensive review of associated full aneuploidy such as trisomy 18, trisomy 13, triploidy, trisomy 21, 45,X, 47,XXY, and 47,XXX, partial aneuploidy such as dup(3q, dup(11p, inv(11, dup(1q, del(1q, dup(4q, dup(5p, dup(6q, del(9p, dup(15q, dup(17q, Pallister-Killian syndrome with mosaic tetrasomy 12p and Miller-Dieker lissencephaly syndrome with deletion of 17p13.3, and uniparental disomy (UPD such as UPD 11 and UPD 14. Omphalocele is a prominent marker for chromosomal abnormalities. Perinatal identification of omphalocele should alert chromosomal abnormalities and familial unbalanced translocations, and prompt thorough cytogenetic investigations and genetic counseling.

  16. Hypothyroidism associated with parathyroid disorders.

    Science.gov (United States)

    Mantovani, Giovanna; Elli, Francesca Marta; Corbetta, Sabrina

    2017-03-01

    Hypothyroidism may occur in association with congenital parathyroid disorders determining parathyroid hormone insufficiency, which is characterized by hypocalcemia and concomitant inappropriately low secretion of parathormone (PTH). The association is often due to loss of function of genes common to thyroid and parathyroid glands embryonic development. Hypothyroidism associated with hypoparathyroidism is generally mild and not associated with goiter; moreover, it is usually part of a multisystemic involvement not restricted to endocrine function as occurs in patients with 22q11 microdeletion/DiGeorge syndrome, the most frequent disorders. Hypothyroidism and hypoparathyroidism may also follow endocrine glands' damages due to autoimmunity or chronic iron overload in thalassemic disorders, both genetically determined conditions. Finally, besides PTH deficiency, hypocalcemia can be due to PTH resistance in pseudohypoparathyroidism; when hormone resistance is generalized, patients can suffer from hypothyroidism due to TSH resistance. In evaluating patients with hypothyroidism and hypocalcemia, physical examination and clinical history are essential to drive the diagnostic process, while routine genetic screening is not recommended.

  17. Antibiotic associated diarrhoea: Infectious causes

    Directory of Open Access Journals (Sweden)

    Ayyagari A

    2003-01-01

    Full Text Available Nearly 25% of antibiotic associated diarrhoeas (AAD is caused by Clostridium difficile, making it the commonest identified and treatable pathogen. Other pathogens implicated infrequently include Clostridium perfringens, Staphylococcus aureus, Klebsiella oxytoca, Candida spp. and Salmonella spp. Most mild cases of AAD are due to non-infectious causes which include reduced break down of primary bile acids and decrease metabolism of carbohydrates, allergic or toxic effects of antibiotic on intestinal mucosa and pharmacological effect on gut motility. The antibiotics most frequently associated with C. difficile associated diarrhoea are clindamycin, cephalosporin, ampicillin and amoxicillin. Clinical presentation may vary from mild diarrhoea to severe colitis and pseudomembranous colitis associated with high morbidity and mortality. The most sensitive and specific diagnostic test for C. difficile infection is tissue culture assay for cytotoxicity of toxin B. Commercial ELISA kits are available. Though less sensitive, they are easy to perform and are rapid. Withdrawal of precipitating antibiotic is all that is needed for control of mild to moderate cases. For severe cases of AAD, oral metronidazole is the first line of treatment, and oral vancomycin is the second choice. Probiotics have been used for recurrent cases.

    2007-11-07

    It has been recently suggested that there are likely generic features characterizing the emergence of systems constructed from the self-organization of self-replicating agents acting under one or more selection pressures. Therefore, structures and behaviors at one length scale may be used to infer analogous structures and behaviors at other length scales. Motivated by this suggestion, we seek to characterize various "animate" behaviors in biochemical networks, and the influence that these behaviors have on genomic evolution. Specifically, in this paper, we develop a simple, chemostat-based model illustrating how a process analogous to associative learning can occur in a biochemical network. Associative learning is a form of learning whereby a system "learns" to associate two stimuli with one another. Associative learning, also known as conditioning, is believed to be a powerful learning process at work in the brain (associative learning is essentially "learning by analogy"). In our model, two types of replicating molecules, denoted as A and B, are present in some initial concentration in the chemostat. Molecules A and B are stimulated to replicate by some growth factors, denoted as G(A) and G(B), respectively. It is also assumed that A and B can covalently link, and that the conjugated molecule can be stimulated by either the G(A) or G(B) growth factors (and can be degraded). We show that, if the chemostat is stimulated by both growth factors for a certain time, followed by a time gap during which the chemostat is not stimulated at all, and if the chemostat is then stimulated again by only one of the growth factors, then there will be a transient increase in the number of molecules activated by the other growth factor. Therefore, the chemostat bears the imprint of earlier, simultaneous stimulation with both growth factors, which is indicative of associative learning. It is interesting to note that the dynamics of our model is consistent with certain aspects of

    Is the presence of adenomyosis associated with menorrhagia? There was no significant association between adenomyosis and menorrhagia, but there was a significant positive correlation between the severity of adenomyosis on ultrasound and the amount of menstrual loss estimated using pictorial blood loss assessment charts. There is no consensus in the literature with regards to the association between adenomyosis and menorrhagia. Previous studies have been limited to retrospective studies of highly selected populations which mainly included women who underwent hysterectomy. There are no large prospective studies evaluating the association between adenomyosis and menorrhagia, either in the general population of women or in a general gynaecology clinic setting. This was a prospective observational study set in the general gynaecology clinic of a university teaching hospital between January 2009 and January 2010. There were 714 consecutive premenopausal women who attended the clinic and underwent structured clinical and transvaginal ultrasound examination in accordance with the study protocol. Morphological features of adenomyosis were systematically recorded on ultrasound scan. Menorrhagia was determined subjectively by direct questioning and objectively by completion of pictorial blood loss analysis charts. A diagnosis of adenomyosis was made in 157/714 women [22.0% (95% CI: 19.1-25.2%)]. Multivariable analysis showed significant associations between submucous fibroids [OR 5.60 (95% CI: 2.69-11.6)], any fibroids [OR 1.53 (95% CI: 0.91-2.58)] and endometrial polyps [OR 2.81 (95% CI: 1.15-11.7)] and menorrhagia. There were also significant associations between increasing gravidity and BMI and menorrhagia (P menorrhagia in the study population, when adenomyosis was assessed as a binary outcome. When severity of adenomyosis was assessed by counting the number of morphological features of adenomyosis in each woman, we found a significant 22% increase in menstrual loss for

  8. Learning: from association to cognition.

    Science.gov (United States)

    Shanks, David R

    2010-01-01

    Since the very earliest experimental investigations of learning, tension has existed between association-based and cognitive theories. Associationism accounts for the phenomena of both conditioning and "higher" forms of learning via concepts such as excitation, inhibition, and reinforcement, whereas cognitive theories assume that learning depends on hypothesis testing, cognitive models, and propositional reasoning. Cognitive theories have received considerable impetus in regard to both human and animal learning from recent research suggesting that the key illustration of cue selection in learning, blocking, often arises from inferential reasoning. At the same time, a dichotomous view that separates noncognitive, unconscious (implicit) learning from cognitive, conscious (explicit) learning has gained favor. This review selectively describes key findings from this research, evaluates evidence for and against associative and cognitive explanatory constructs, and critically examines both the dichotomous view of learning as well as the claim that learning can occur unconsciously.

Very few cases of vancomycin-associated leukocytoclastic vasculitis have been published. We report on a patient who developed pruritus and palpable purpura in both lower extremities after receiving six days of intravenous vancomycin. Skin biopsy revealed leukocytoclastic vasculitis.

  10. Ion association in natural brines

    Truesdell, A.H.; Jones, B.F.

    1969-01-01

    Natural brines, both surface and subsurface, are highly associated aqueous solutions. Ion complexes in brines may be ion pairs in which the cation remains fully hydrated and the bond between the ions is essentially electrostatic, or coordination complexes in which one or more of the hydration water molecules are replaced by covalent bonds to the anion. Except for Cl-, the major simple ions in natural brines form ion pairs; trace and minor metals in brines form mainly coordination complexes. Limitations of the Debye-Hu??ckel relations for activity coefficients and lack of data on definition and stability of all associated species in concentrated solutions tend to produce underestimates of the degree of ion association, except where the brines contain a very high proportion of Cl-. Data and calculations on closed basin brines of highly varied composition have been coupled with electrode measurements of single-ion activities in an attempt to quantify the degree of ion association. Such data emphasize the role of magnesium complexes. Trace metal contents of closed basin brines are related to complexes formed with major anions. Alkaline sulfo- or chlorocarbonate brines (western Great Basin) carry significant trace metal contents apparently as hydroxides or hydroxy polyions. Neutral high chloride brines (Bonneville Basin) are generally deficient in trace metals. With a knowledge of the thermodynamic properties of a natural water, many possible reactions with other phases (solids, gases, other liquids) may be predicted. A knowledge of these reactions is particularly important in the study of natural brines which may be saturated with many solid phases (silicates, carbonates, sulfates, etc.), which may have a high pH and bring about dissolution of other phases (silica, amphoteric hydroxides, CO2, etc.), and which because of their high density may form relatively stable interfaces with dilute waters. ?? 1969.

    Josse, Julie; Holmes, Susan

    2017-01-01

    Simple correlation coefficients between two variables have been generalized to measure association between two matrices in many ways. Coefficients such as the RV coefficient, the distance covariance (dCov) coefficient and kernel based coefficients are being used by different research communities. Scientists use these coefficients to test whether two random vectors are linked. Once it has been ascertained that there is such association through testing, then a next step, often ignored, is to explore and uncover the association’s underlying patterns. This article provides a survey of various measures of dependence between random vectors and tests of independence and emphasizes the connections and differences between the various approaches. After providing definitions of the coefficients and associated tests, we present the recent improvements that enhance their statistical properties and ease of interpretation. We summarize multi-table approaches and provide scenarii where the indices can provide useful summaries of heterogeneous multi-block data. We illustrate these different strategies on several examples of real data and suggest directions for future research. PMID:29081877

    Boyatzis, C J; Varghese, R

    1994-03-01

    In this study children's emotional associations with colors were investigated. Sixty children (30 girls, 30 boys), equally divided into groups of 5-year-olds and 6 1/2-year-olds, were asked their favorite color and were then shown nine different colors, one at a time and in a random order. For each color, children were asked, "How does (the color) make you feel?" All children were able to verbally express an emotional response to each color, and 69% of children's emotional responses were positive (e.g., happiness, excitement). Responses also demonstrated distinct color-emotion associations. Children had positive reactions to bright colors (e.g., pink, blue, red) and negative emotions for dark colors (e.g., brown, black, gray). Children's emotional reactions to bright colors became increasingly positive with age, and girls in particular showed a preference for brighter colors and a dislike for darker colors. Boys were more likely than girls were to have positive emotional associations with dark colors. Potential sources for children's color-emotion concepts, such as gender-related and idiosyncratic experiences, are discussed.

    2002-02-01

    Tics are the most frequent abnormal movements in children. This is one reason for their importance. Another reason is their relationship to fascinating disturbances of human behaviour such as compulsion and obsessions. Several 'behavioural disorders', mainly attention-deficit hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD), are more frequent in patients with tics than in the general population. These associated disorders (named 'comorbid') are probably of more consequence than the tics. Relationship between tics and comorbid disorders is not well known. This review considers data, consequences, hypothesis and management of comorbid disorders associated to tics. From the personal series of children with tics, data of comorbid disorders associated to tics was analysed. Of 340 cases of tics, 132 (39%) cases have ADHD, 135 (40%) cases have OCD, obsessive compulsive symptoms (OCS) or obsessive-compulsive behaviour (OCB). 68 (20%) cases have both ADHD and OCD. Considering only Tourette cases (219) the figures are only slight higher: ADHD (42%), OCD (45%) and ADHD plus OCD (24%) suggesting that all the spectrum of tics has a common basis. Familial studies shows that 44 percent of the patients with tics have a positive familial history of tics and 30 percent positive familial history of obsessive compulsive signs. The data of the literature on the tics and comorbid disorders relationship is also revised.

    Full Text Available HIV infection is associated with disturbances in brain function referred to as HIV-associated neurocognitive disorders (HAND. This literature review outlines the recently revised diagnostic criteria for the range of HAND from the earliest to the more advanced stages: (i asymptomatic neurocognitive impairment; (ii mild neurocognitive disorder; and (iii HIV-associated dementia. Relevant literature is also reviewed regarding the differential impact upon component cognitive domains known to be affected in HAND, which in turn should ideally be targeted during clinical and neuropsychological assessments: psychomotor and information processing speed, learning and memory, attention and working memory, speech and language, executive functioning and visuospatial functioning. A discussion outlining the neuropsychological tools used in the diagnostic screening of HAND is also included. The central mechanisms of HAND appear to revolve primarily around psychomotor slowing and cognitive control over mental operations, possibly reflecting the influence of disrupted fronto-striatal circuits on distributed neural networks critical to cognitive functions. The accurate assessment and diagnosis of HAND depends on meeting the need for statistically sound neuropsychological assessment techniques that may be used confidently in assessing South African populations, as well as the development of relevant norms for comparison of test performance data.

  20. A PROPOSAL OF FUZZY MULTIDIMENSIONAL ASSOCIATION RULES

    2006-01-01

    Full Text Available Association rules that involve two or more dimensions or predicates can be referred as multidimensional association rules. Rather than searching for frequent itemsets (as is done in mining single-dimensional association rules, in multidimensional association rules, we search for frequent predicate sets. In general, there are two types of multidimensional association rules, namely interdimension association rules and hybrid-dimension association rules. Interdimension association rules are multidimensional association rules with no repeated predicates. This paper introduces a method for generating interdimension association rules. A more meaningful association rules can be provided by generalizing crisp value of attributes to be fuzzy value. To generate the multidimensional association rules implying fuzzy value, this paper introduces an alternative method for mining the rules by searching for the predicate sets.

    Several major association fiber tracts are known to be part of the language processing system. There is evidence that high angular diffusion-based MRI is able to separate these fascicles in a constant way. In this study, we wanted to proof this thesis using a novel whole brain "global tracking" approach and to test for possible lateralization. Global tracking was performed in six healthy right-handed volunteers for the arcuate fascicle (AF), the medial longitudinal fascicle (MdLF), the inferior fronto-occipital fascicle (IFOF), and the inferior longitudinal fascicle (ILF). These fiber tracts were characterized quantitatively using the number of streamlines (SL) and the mean fractional anisotropy (FA). We were able to characterize the AF, the MdLF, the IFOF, and the ILF consistently in six healthy volunteers using global tracking. A left-sided dominance (LI > 0.2) for the AF was found in all participants. The MdLF showed a left-sided dominance in four participants (one female, three male). Regarding the FA, no lateralization (LI > 0.2) could be shown in any of the fascicles. Using a novel global tracking algorithm we confirmed that the courses of the primary language processing associated fascicles can consistently be differentiated. Additionally we were able to show a streamline-based left-sided lateralization in the AF of all right-handed healthy subjects.

    Schizophrenia is a psychiatric disorder with large personal and social costs, and understanding the genetic etiology is important. Such knowledge can be obtained by testing the association between a disease phenotype and individual genetic markers; however, such single-marker methods have limited...... power to detect genetic markers with small effects. Instead, aggregating genetic markers based on biological information might increase the power to identify sets of genetic markers of etiological significance. Several set test methods have been proposed: Here we propose a new set test derived from...... genomic best linear unbiased prediction (GBLUP), the covariance association test (CVAT). We compared the performance of CVAT to other commonly used set tests. The comparison was conducted using a simulated study population having the same genetic parameters as for schizophrenia.

    Darkening of the tongue and oral mucosa is a reaction pattern that can be related to a number of physiologic, metabolic, and toxic disorders, and medications and exogenous substances. Black discoloration of the tongue should be distinguished from black "hairy" tongue, which is characterized by hypertrophy of the filiform papillae. We report a case of a 42-year-old man presented with a black discoloration of his tongue during treatment with linezolid for spondylodiscitis. So in conclusion, tongue discoloration is a benign and reversible condition and a probable adverse event associated with linezolid. We present this case to increase clinicians' awareness of a new potential adverse effect of linezolid.

    Erythema multiforme is a cutaneous reaction that has only rarely been described in varicella zoster virus infection. We describe a 76-year old immunocompetent male patient with thoracic herpes zoster. While treated with oral brivudin he developed a widespread cutaneous erythema multiforme. The lesions completely cleared with two weeks with systemic corticosteroids. Varicella zoster infections are possible triggers of erythema multiforme and this is the oldest patient reported with such an association. Brivudin itself has not been reported to induce erythema multiforme and is an unlikely cause of disease in our patient.

    We present a next-to-next-to-leading order accurate description of associated HW production consistently matched to a parton shower. The method is based on reweighting events obtained with the HW plus one jet NLO accurate calculation implemented in POWHEG, extended with the MiNLO procedure, to reproduce NNLO accurate Born distributions. Since the Born kinematics is more complex than the cases treated before, we use a parametrization of the Collins-Soper angles to reduce the number of variables required for the reweighting. We present phenomenological results at 13 TeV, with cuts suggested by the Higgs Cross Section Working Group.

Therefore, patients must carefully decide whether their purpose of undergoing orthognathic surgery lies on the aesthetic side or the functional side. There is a wide variety of complications associated with orthognathic surgery. There should be a clear distinction between malpractice and complications. Complications can be resolved without any serious problems if the cause is detected early and adequate treatment provided. Oral and maxillofacial surgeons must have a full understanding of the types, causes, and treatment of complications, and should deliver this information to patients who develop these complications.

    APL provides convenient associative data manipulation functions in a high level language. Six statements were added to PL/1 via a preprocessor: CREATE, INSERT, FIND, FOR EACH, REMOVE, and DELETE. They allow complete control of all data base operations. During execution, data base management programs perform the functions required to support the APL language. VAAM is the data base management system designed to support the APL language. APL/VAAM is used by CADANCE, an interactive graphic computer system. VAAM is designed to support heavily referenced files. Virtual memory files, which utilize the paging mechanism of the operating system, are used. VAAM supports a full network data structure. The two basic blocks in a VAAM file are entities and sets. Entities are the basic information element and correspond to PL/1 based structures defined by the user. Sets contain the relationship information and are implemented as arrays.

    2014-12-01

    Diabetes is the leading cause of neuropathy worldwide and, due to the epidemic progression of the affection, prevalence of diabetic neuropathies will increase in the near future. Beside the typical diabetic neuropathy pattern and the common entrapment neuropathies, several unusual clinical forms have been described with either a symmetrical or an asymmetrical pattern. Treatment-induced neuropathy is an acute sensory affection most commonly related to acute glycemic control. Pain is debilitating and associated with vegetative dysfunction. Prevention is important, as resolution is often incomplete. Several patterns or asymmetrical neuropathies of inflammatory and ischemic origin were described long ago in the lower limb. They are debilitating, most often painful and require steroid treatment. Other patterns affecting the thoracolumbar region or the upper limbs or involving a painless motor deficit must be identified as specific treatments are sometimes needed. An association between diabetes and chronic inflammatory demyelinating polyneuropathy has not been demonstrated but diagnosis may be suggested due to the misleading low conduction velocities seen in classical diabetic neuropathy. Like any other patient, the diabetic patient may present a neuropathy unrelated to diabetes. To facilitate patient care, neurologists should be aware of such clinical entities.

    Yet uncommon, blindness is a potential associated injury of facial fractures. Epidemiology, mechanisms, fracture types, and outcome of facial fractures-associated blindness in a 10-year period are retrospectively reviewed. Out of 907 facial fractures patients, 10 had blindness, giving a frequency of 1.1%. There were 9 men and 1 woman whom age range was 6 to 59 years (mean: 31.2 years). Intentional injury patients were significantly the most at risk of blindness (P = 0.02). In all the patients, the fracture involved at least 1 of the orbit walls. Risk of blindness was significantly higher in naso-fronto-orbito-ethmoidal complex fractures (P = 0.03). The vision loss was recorded in 13 eyes (unilateral in 7 patients and bilateral in 3). Its predominant mechanism was a globe rupture or perforation, recorded in 8 eyes. A treatment with intention to improve the vision was attempted in 1 patient only. None of the patients had vision recovery. The findings of this study commend comprehensive ophthalmologic evaluation in any patient with an orbit wall fracture.

    Hypercalcaemia due to primary hyperparathyroidism is a rare cause of acute pancreatitis, with a reported prevalence of 1.5 to 8%. There is no clear pathophysiological basis, but elevated parathyroid hormone and high serum calcium levels could be responsible for calcium deposit in the pancreatic ducts and activation of pancreatic enzymes, which may be the main risk factor for developing acute pancreatitis. The aim of this report is to describe four cases. Four cases are reported of severe pancreatitis associated with hypercalcaemia secondary to primary hyperparathyroidism; three of them with complications (two pseudocysts and one pancreatic necrosis). Cervical ultrasound, computed tomography, and scintigraphy using 99mTc-Sestambi, studies showed the parathyroid adenoma. Surgical resection was the definitive treatment in all four cases. None of the patients had recurrent acute pancreatitis events during follow-up. Acute pancreatitis secondary to hypercalcaemia of primary hyperparathyroidism is rare; however, when it occurs it is associated with severe pancreatitis. It is suspected in patients with elevated serum calcium and high parathyroid hormone levels. Imaging techniques such as cervical ultrasound, computed tomography, and scintigraphy using 99mTc-Sestambi, should be performed, to confirm clinical suspicion. Surgical resection is the definitive treatment with excellent results. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A. All rights reserved.

    The prevalence of radiation-associated cardiac disease is increasing due to prolonged survival following mediastinal irradiation. Side effects of radiation include pericarditis, accelerated coronary artery disease, myocardial fibrosis and valvular injury. We evaluated the cases of three young patients with evidence of significant valvular disease following mediastinal irradiation. One patient underwent the first reported successful aortic and mitral valve replacement for radiation-associated valvular disease (RAVD) as well as concurrent coronary artery revascularization. A review of the literature revealed 35 reported cases of RAVD, with only one successful case of valve replacement that was limited to the aortic valve. Asymptomatic RAVD is diagnosed 11.5 years after mediastinal irradiation compared with 16.5 years for symptomatic patients, emphasizing that long-term follow-up is important for patients receiving mediastinal irradiation. This study defines a continuum of valvular disease following radiation that begins with mild asymptomatic valvular thickening and progresses to severe valvular fibrosis with hemodynamic compromise requiring surgical intervention. 32 refs.

    Although rosacea is a common disease, the cause of disease is still a mystery -Helicobacter pylori infection, genetic predisposition, climatic factors, and detrimental habits are implicated as triggers of rosacea. The aim of current study is to evaluate several suspected risk factors coincidently. Patients with rosacea from a dermatology clinic and skin-healthy controls from an randomly selected employees' population enrolled the study. Skin status were evaluated by one and same dermatologist. Participants were queried for age, gender, sun-reactive skin type, and detrimental habits using a questionnaire; blood samples for detecting Helicobacter pylori serostatus were collected. Totally 145 skin-healthy controls and 172 subjects either with flushing episodes or established rosacea included the study. In multivariate analysis, rosacea patients had significantly higher chance to have photosensitive skin types (OR 1.75; 95% CI 1.01-3.04; P < 0.05), positive family history to rosacea (OR 4.31; 95% CI 2.34-7.92; P < 0.0001) or previous smoking status (OR 2.01; 95% CI 1.07-3.80; P < 0.05) comparing with skin-healthy controls. There were no statistically significant differences either in gender, Helicobacter pylori serostatus, caffeine intake, alcohol consumption, occupational environment, or education level between rosacea patients and controls. Rosacea is foremost associated with familial predisposition. There is no association between Helicobacter pylori infection and rosacea in current study.

    2009-10-01

    Full Text Available ANCA associated vasculitis (AAV comprises three syndromes with systemic vasculitis (Wegener’s granulomatosis (WG, Churg Strauss syndrome (CSS and icroscopic polyangiitis (MPA, which all involve small and medium sized vessels and are associated with antibodies against cytoplasmatic antibodies in neutrophils (ANCA. Polyarteritis nodosa (PAN is included in this review as it also affects medium sized vessels, and has many clinical findings in common with the AAV.Since the recognition of ANCA, increasing data have become available on the epidemiology of these vasculitidis. WG constitutes half of the AAV and its prevalence has increased from 30/million in the late 1980’s in the USA to 160/million in this century in northern Europe. The prevalence for the whole group of primary systemic vasculitides is now 300/million in Sweden. The annual incidence of WG increased from 6.0/million to 14/million during the 1990’s in Tromsø, but it is unknown if this is a true increase or the result of an increased awareness of the diagnosis. For the whole group of AAV, the annual incidence in most more recent studies is relatively constant over time and by geographical location, ranging from 13 to 21/million. Nonetheless there are interesting differences in the prevalence of specific vasculitis between different geographical areas, as well as for sub specificities of ANCA.There seems to be a South-North gradient for WG and PR3-ANCA with high figures reported from northern Europe and southern New Zealand. In European studies WG is 90% PR3-ANCA positive. MPA which is predominantly MPO-ANCA associated are more frequent in the Mediterranean countries and also has an increasing gradient towards east-Asia, as almost all AAV in China and Japan are diagnosed as MPA, predominantly MPO-ANCA positive.There are also some ethnic and gender differences. WG is most prevalent among Caucasians in the USA and in people with European ancestors in Paris and in New Zealand, less

    To estimate epidemiologic risk factors for cerebral palsy. Data were collected by linkage to state-based perinatal repositories and cerebral palsy registers and using a maternal questionnaire. The cohort included 587 individuals with cerebral palsy and 1,154 non-cerebral palsy controls. The following factors were associated with cerebral palsy: recorded maternal infection during pregnancy (41.4% patients compared with 31.3% controls; odds ratio [OR] 1.55, 95% confidence interval 1.26-1.91), small for gestational age ([birth weight less than third customized centile] 43.9% patients compared with 6.3% controls; OR 11.75, 6.25-22.08), gestational age less than 32 weeks (29.3% patients compared with 0.7% controls; OR 59.20, 28.87-121.38), multiple birth (OR 6.62, 4.00-10.95), a relative with cerebral palsy (OR 1.61, 1.12-2.32), breech position (13.7% patients compared with 6.0% controls; OR 2.48, 1.76-3.49), bleeding at any time in pregnancy (29.3% patients compared with 16.9% controls; OR 2.04, 1.61-2.58), male sex (58.8% patients compared with 45.8% controls; OR 1.68, 1.38-2.06), multiple miscarriage (7.7% patients compared with 3.5% controls; OR 2.30, 1.38-3.82), smoking (14.0% patients compared with 10.6% controls; OR 1.37, 1.02-1.85), and illicit drug use (3.3% patients compared with 1.5% controls; OR 2.22, 1.14-4.30). Factors not associated with cerebral palsy were "disappearing twin," diabetes, maternal body mass index, hypertension, alcohol consumption, anemia, maternal hypothyroidism, forceps or vacuum delivery, and maternal age. Preterm birth, intrauterine growth restriction, perinatal infection, and multiple birth present the largest risks for a cerebral palsy outcome. Reassuringly, upper respiratory tract and gastrointestinal infections during pregnancy were not associated with cerebral palsy. II.

  4. Risks associated with ionizing radiation.

    Little, M P

    2003-01-01

    This paper reviews current knowledge on the deterministic and stochastic risks (the latter including the risk of cancer and of hereditary disease) associated with exposure to ionizing radiation. Particular attention is paid to cancer risks following exposure to man-made low linear energy transfer radiation. Excess cancer risks have been observed in the Japanese atomic bomb survivors and in many medically and occupationally exposed groups. In general, the relative risks among Japanese survivors of atomic-bomb explosions are greater than those among comparable subsets in studies of medically exposed individuals. Cell sterilization largely accounts for the discrepancy in relative risks between these two populations, although other factors may contribute, such as the generally higher underlying cancer risks in the medical series than in the Japanese atomic bomb survivors. Risks among occupationally exposed groups such as nuclear workforces and underground miners are generally consistent with those observed in the Japanese atomic bomb survivors.

  5. Pseudopheochromocytoma Associated with Domestic Assault

    Directory of Open Access Journals (Sweden)

    H. M. Le

    2016-01-01

    Full Text Available Pseudopheochromocytoma has a clinical presentation that is similar to pheochromocytoma. It manifests itself with paroxysmal hypertension crises, associated with various symptoms such as headaches, chest pain, nausea, palpitations, and dizziness. Patients are usually asymptomatic in between the crises. Unlike pheochromocytoma, there is no catecholamines overproduction in this pathology: hypertensive peaks are caused by a hyperactivation of the sympathetic nervous system, which is often triggered by a psychological trauma in the past. Treatment of pseudopheochromocytoma can be challenging due to normal blood pressure values in between the hypertensive peaks; it includes alpha- and beta-blockers for moderate crises and prevention and must be combined with psychopharmacologic agents such as anxiolytics or antidepressant drugs. Psychotherapy and dietetic treatment are also crucial in pseudopheochromocytoma management.

    Sarcoidosis is a systemic granulomatous inflammation of unknown etiology, and seems to involve the liver parenchyma in most cases. However, sarcoidosis-associated hepatocellular carcinoma is rare. We report here a case in which a hepatocellular carcinoma occurred within the liver, which was probably involved as a result of systemic sarcoidosis. A 57-year-old Japanese man had been followed up for 2 years because of diabetic nephropathy and sarcoidosis. On admission for pneumonia, imaging studies revealed an unexpected hepatic tumor. Histology revealed a hepatocellular carcinoma accompanied by T-lymphocytic infiltration and marked granulomatous inflammation, which was surrounding some tumor nodules. The background liver parenchyma exhibited a moderate degree of fibrosis with granulomatous inflammation. The patient had no other apparent liver disease such as viral hepatitis, steatohepatitis, or primary biliary cirrhosis. Therefore, in the present case, sarcoidosis may be considered the probable background etiology for hepatocarcinogenesis.

    2009-04-01

    There is increasing evidence for the use of epidermal growth factor receptor (EGFR) inhibitors in head and neck, non-small-cell lung, and colorectal cancers. We report the case of a 78-year-old man with metastatic colorectal cancer (CRC) involving liver and lung who received cetuximab plus irinotecan as third-line treatment. Two months later, he presented with signs and symptoms consistent with bronchiolotis obliterans organizing pneumonia secondary to cetuximab. Reports of cetuximab-associated pulmonary toxicity are rare, although there have been extensive reports of interstitial fibrosis with the use of other EGFR inhibitors such as gefitinib and erlotinib. There are many causes of pulmonary infiltrates in patients treated for advanced CRC, and this case highlights the importance of considering drug toxicity.

    Pulmonary manifestations are frequently observed in children, pregnant women and travellers with malaria. The pathophysiology of these pulmonary manifestations is poorly understood but would appear to be secondary to an interaction between the parasitized red cells and the pulmonary capillary endothelium. Bronchitis and pneumonia do not directly compromise outcome but, left unrecognized, the delay in diagnosis and treatment may be fatal. Acute respiratory distress in children is the first cause of overmortality, coming before neurological involvement. The acute respiratory distress caused by severe malaria has no specific characteristics. Iatrogenic complications and pulmonary superinfections must be differentiated. The prevention of pulmonary manifestations associated with malaria can easily be accomplished by limiting water intake and carefully monitoring urinary output and weight. Treatment is the same as for acute flare-ups in combination with symptomatic respiratory treatment when required.

  9. Antisperm antibodies and fertility association.

    Restrepo, B; Cardona-Maya, W

    2013-10-01

    To evaluate the relation between antisperm antibodies (ASA) and human fertility by reviewing the scientific literature of the last 45 years. We carried out a review of scientific literature about antisperm antibodies and infertility published in spanish or english in databases as Pubmed, Medline, Scielo, some books and another gray literature include information related to this review and that is published in the last 45 years. Infertile couples suffer infertility by immunological mechanisms mainly by the presence of antisperm antibodies ASA in blood, semen or cervicovaginal secretions; the formation of ASA in men and women may be associated with disturbance in immunomodulatory mechanisms that result in functional impairment of sperm and thus its inability to fertilize the oocyte. Immunological infertility caused by ASA is the result of interference of these antibodies in various stages of fertilization process, inhibiting the ability of interaction between sperm and oocyte.

    Variations in the electromagnetic wavelengths of absorption and reflection of molecules do not only make life colorful but also are often of central importance in solar energy conversion and optoelectronic information processing and transfer. Dithizone and its derivatives and complexes are, to our knowledge, probably the most "colorful" compound, being responsive to no less than seven different external stimuli that effect color change. Apart from a more detailed discussion of the cyclic voltammetry and observed electrochromism in the SCH3-substituted free ligand and mercury complex, concentratochromism, solvatochromism, halochromism, thermochromism, and chronochromism in the ligand, and photochromism in the carboxy-functionalized phenylmercury(II) complex are also presented here. Color changes are either associated with proton transfer or loss, or isomerization.

    2014-11-01

    We report on three children with bilateral, congenital clubfoot. Four of the six clubfeet were associated with preaxial polydactyly. Five of the six clubfeet were treated without extensive surgery. A plantigrade foot was achieved, even in the three clubfeet with polydactyly, using serial casting and percutaneous Achilles tenotomy. Casting was adapted according to the existing polydactyly. One case with tibial hemimelia and a complex clubfoot deformity with preaxial tarsal polydactyly required more comprehensive surgery. A foot with good weight-bearing function was also achieved in this case following resection of the accessory medial ray, including resection of the accessory tarsal bones and posterior release. Remaining limitations in mobility were ascribed to hindfoot pathologies.

    Autism is a heterogeneous neurodevelopmental disorder with a variety of different etiologies, but with a heritability estimate of more than 90%. Although the strong correlation between autism and genetic factors has been long established, the exact genetic background of autism is still unclear. This review refers to all the genetic syndromes that have been described in children with pervasive developmental disorders (tuberous sclerosis, fragile X, Down, neurofibromatosis, Angelman, Prader-Willi, Gilles de la Tourette, Williams, etc.). Issues covered include prevalence and main characteristics of each syndrome, as well as the possible base of its association with autism in terms of contribution to the current knowledge on the etiology and genetic base of pervasive developmental disorders.

    Full Text Available We report a rare case of bilateral keratoconus in association with achondroplasia. A 26-year-old male, with a known case of achondroplasia, complained of bilateral gradual deterioration in vision for the past few years. Slit lamp biomicroscopy showed bilateral central corneal protrusion and stromal thinning at the apex consistent with keratoconus. a trial of hard contact lens fitting failed to improve VA in the left eye (LE. Right eye (RE improved to 20/25. The patient underwent penetrating keratoplasty (PKP in his LE. Twenty-seven months postoperatively, uncorrected visual acuity (UCVA was 20/30. Ophthalmologists should be aware that patients with achondroplasia who complain of poor vision should be suspected of having keratoconus once other more common conditions are ruled out.

  15. Poor reproducibility of allergic rhinitis SNP associations.

    Daniel Nilsson

    Full Text Available Replication of reported associations is crucial to the investigation of complex disease. More than 100 SNPs have previously been reported as associated with allergic rhinitis (AR, but few of these have been replicated successfully. To investigate the general reproducibility of reported AR-associations in candidate gene studies, one Swedish (352 AR-cases, 709 controls and one Singapore Chinese population (948 AR-cases, 580 controls were analyzed using 49 AR-associated SNPs. The overall pattern of P-values indicated that very few of the investigated SNPs were associated with AR. Given published odds ratios (ORs most SNPs showed high power to detect an association, but no correlations were found between the ORs of the two study populations or with published ORs. None of the association signals were in common to the two genome-wide association studies published in AR, indicating that the associations represent false positives or have much lower effect-sizes than reported.

    Anti-mTOR may induce proteinuria when utilized after renal transplantation. Little is known about the pathogenesis and composition of proteinuria. To clarify this unresolved aspect, we analyzed urinary protein composition utilizing an integrated proteomics approach, including quantitative assays, 2-dimensional electrophoresis, MALDI-TOF, and Western blots among 48 renal transplant recipients treated with everolimus (EVL; n = 31) or enteric-coated mycophenolic acid (EC-MPA; n = 17). High (>3 g/d) or intermediate levels of proteinuria (1-3 g) developed in 12 EVL patients (39%) compared with 4 subjects (23%) in the EC-MPA group. Proteinuria, which started during the first 2 days after EVL, tended to reduce during the follow-up. Quantitative proteomics showed an increase in low molecular proteins beta2 microglobulin (P < .001) and alpha1 microglobulin (P < .025). Qualitative proteomics showed a marked increase among all urinary components in EVL and EC-MPA patients. Major changes involved typical components of glomerular damage: albumin, Zn-alpha1 glycoprotein, alpha2HS glycoprotein, and leucine-rich alpha2 glycoprotein. In addition, we observed specific biomarkers for EVL: clusters of alpha1-antitrypsin fragments and monoclonal lambda chains. In conclusion, EVL induced proteinuria of a mixed glomerular and tubular origin that correlated with the start of treatment and reached nephrotic ranges in few cases. The specific urinary markers may reflect renal alterations related to the transplant or specific alterations associated with the drug.

    Microscopic entities, microorganisms that drastically affect human health need to be thoroughly investigated. A biofilm is an architectural colony of microorganisms, within a matrix of extracellular polymeric substance that they produce. Biofilm contains microbial cells adherent to one-another and to a static surface (living or non-living). Bacterial biofilms are usually pathogenic in nature and can cause nosocomial infections. The National Institutes of Health (NIH) revealed that among all microbial and chronic infections, 65% and 80%, respectively, are associated with biofilm formation. The process of biofilm formation consists of many steps, starting with attachment to a living or non-living surface that will lead to formation of micro-colony, giving rise to three-dimensional structures and ending up, after maturation, with detachment. During formation of biofilm several species of bacteria communicate with one another, employing quorum sensing. In general, bacterial biofilms show resistance against human immune system, as well as against antibiotics. Health related concerns speak loud due to the biofilm potential to cause diseases, utilizing both device-related and non-device-related infections. In summary, the understanding of bacterial biofilm is important to manage and/or to eradicate biofilm-related diseases. The current review is, therefore, an effort to encompass the current concepts in biofilm formation and its implications in human health and disease. Copyright © 2017.

    Full Text Available Nelarabine (ara-G; Arranon; compound 506U78 is an antineoplastic purine analog used for the treatment of refractory or relapsed T-cell acute lymphoblastic leukemia (T-ALL and T-cell lymphoblastic lymphoma (T-LBL. The drug was granted accelerated approval in October 2005 by the US Food and Drug Administration (FDA given the efficacy (induction of complete responses noted in 2 single-arm trials (one in pediatric setting and one in adult patient population. The main spectra of toxicities that have been reported in these clinical trials and subsequent studies are hematological and neurological. Nelarabine induced rhabdomyolysis and increased creatinine phosphokinase (CK; CPK levels apparently have been reported and this side effect has been added as an adverse reaction in the product monograph from the drug company during postmarketing surveillance. However, the true extent and incidence of the myotoxicity from the drug are unclear. In this paper we report a grade IV CK elevation and rhabdomyolysis in a patient with T-ALL treated with nelarabine. Given the reported finding, we examined the literature further for myotoxicity, increased CK, and/or rhabdomyolysis associated with the use of the nelarabine and report our findings.

    Full Text Available Although exact statistics are lacking, body modifications for cosmetic purposes are performed in many countries. The commonest forms include tattooing, body piercing, and breast and facial augmentation using implants or injectable fillers. Liposuction and, to a lesser extent, mesotherapy are also practiced in many countries. Infective complications of these procedures include local infections, transmission of bloodborne pathogens (viral hepatitis and human immunodeficiency virus, and distant infections such as infective endocarditis. Presence of foreign bodies, long healing time of piercing wounds, and poor compliance with infection control practices of some practitioners all predispose the recipients to infections. Apart from the endogenous microbial flora of the skin and mucosae, atypical mycobacteria, especially the rapid growers, have emerged as some of the most important pathogens in such settings. Outbreaks of infection are commonly reported. We hereby review the current knowledge of the topic with specific focus on infections associated with tattooing, body piercing, breast augmentation, mesotherapy, liposuction, and tissue filler injections. Greater awareness among consumers and health-care professionals, as well as more stringent regulations by the health authorities, is essential to minimize the health risks arising from these procedures.

    Eumycetoma is a morbid chronic granulomatous subcutaneous fungal disease. Despite high environmental exposure to this fungus in certain regions of the world, only few develop eumycetoma for yet unknown reasons. Animal studies suggest that co-infections skewing the immune system to a Th2-type response enhance eumycetoma susceptibility. Since chronic schistosomiasis results in a strong Th2-type response and since endemic areas for eumycetoma and schistosomiasis do regionally overlap, we performed a serological case-control study to identify an association between eumycetoma and schistosomiasis. Compared to endemic controls, eumycetoma patients were significantly more often sero-positive for schistosomiasis (p = 0.03; odds ratio 3.2, 95% CI 1.18–8.46), but not for toxoplasmosis, an infection inducing a Th1-type response (p = 0.6; odds ratio 1.5, 95% CI 0.58–3.83). Here, we show that schistosomiasis is correlated to susceptibility for a fungal disease for the first time. PMID:23717704

  1. Associations between nutrition and cataract.

    Science.gov (United States)

    Taylor, A

    1989-08-01

    Blindness due to opacification of the lens, or cataract, afflicts 50 million persons worldwide. In the United States over 541,000 cataract extractions are done annually at a cost of over $3.8 billion. Conservative estimates indicate that the prevalences of cataracts in Americans aged 65-75 and 75-85 years are 18% and 46%, respectively. Cataracts are even more prevalent in some other populations. It is estimated that the need for cataract extractions would be diminished by half if onset of cataract could be delayed by only ten years. Hypotheses regarding the etiology of cataract include oxidative perturbations of protein metabolism, diverse pathologic conditions, and perhaps glycation of lens proteins. Epidemiologic data indicate that elevated plasma levels of specific nutrients (i.e., carotenoids, ascorbate, tocopherol, and taurine) are associated with diminished incidence of certain types of cataract. Biochemical evidence suggests that each of these compounds can delay photooxidative damage to lens proteins. Roles in lens metabolism for selenium and tryptophan have been suggested. Elucidation of mechanisms by which caloric restriction delays cataract development is a promising area of current research.

    To analyze the association between paracoccidioidomycosis (Pcm) and cancer in a series of 25 cases and to review the literature on this topic. A retrospective review of 25 cases diagnosed with Pcm and cancer, retrieved from a series of 808 consecutive adult patients diagnosed with Pcm based on tests conducted in the Mycology Laboratory of the Santa Casa Complexo Hospitalar, in the city of Porto Alegre, Brazil, between 1972 and 2007. The diagnosis of Pcm was confirmed by means of direct microscopic examination, histopathological examination or immunodiffusion test. All cancer cases were confirmed by histopathological or cytopathological examination. Respiratory symptoms were the principal complaints of the patients evaluated. Pulmonary involvement predominated, followed by skin and lymph node involvement. The most prevalent tumor was bronchial carcinoma, in 15 patients, followed by other types of carcinoma, and 1 patient had Hodgkin's lymphoma. In 16 patients (64%), the site of the Pcm was the same as that of the tumor. In most cases, Pcm treatment consisted of the isolated administration of sulfanilamide, sulfamethoxazole-trimethoprim, ketoconazole, itraconazole or amphotericin B. The most common treatment for cancer was surgery, followed by radiotherapy and chemotherapy. Of the 25 patients, 12 were cured of Pcm, and 4 died. In 9 patients, the final outcome was unknown. In the general population of the area under study, the prevalence of lung cancer was significantly higher in smokers with Pcm than in smokers without Pcm (p Pcm appears to increase the risk of lung cancer.

    Full Text Available Thyroid hemiagenesis (TH, very rare congenital anomaly, is generally asymptomatic. We report two cases of TH with hyperthyroidism. Case One. The patient presented with signs and symptoms of thyrotoxicosis. Physical examination revealed asymmetric nodular goitre at right lobe. Biochemical analysis revealed the diagnosis of hyperthyroidism. Ultrasound showed multinodular hypertrophy in the right lobe and absence of the left lobe. Nuclear scan, confirming absence of the left lobe, showed hot nodules in the right one. The diagnosis was toxic multinodular goitre. Case Two. The thyroid was not palpable in this patient presented with signs and symptoms of thyrotoxicosis. Biochemical analysis revealed the diagnosis of autoimmune thyrotoxicosis. Ultrasound showed mild diffuse hyperplasia of the right lobe and agenesis of the left lobe. Nuclear scan, confirming absence of the left lobe, showed increasing diffuse uptake of radiotracer in the right one. The diagnosis was Graves’ disease in this patient. After antithyroid medication, the patients were surgically treated with total excision of the thyroid tissue. TH is sometimes associated with disorders of the thyroid. Hyperthyroidism makes TH cases symptomatic. During evaluation of patients, ultrasound and nuclear scan usually report agenesis of one lobe and establish the diagnosis of TH. The surgical treatment is total removal of hyperactive tissue and total excision of the remaining lobe.

    2016-05-01

    Achondroplasia is the most common skeletal dysplasia. This form of dwarfism is caused by a point mutation in the fibroblast growth factor receptor 3 (FGFR3) gene, leading to inhibition of endochondral ossification for these patients. This results in a normal trunk height but shortened limbs. The discoid meniscus may be an important associated finding to better understand the common complaints of leg pain for these patients. Although the incidence for a discoid meniscus is between 3% and 5% for the general population, it is unknown with achondroplasia. This case series includes 4 patients, with ages ranging from adolescence to early adulthood, with symptoms of knee pain that were not attributable to some of the more common findings seen in this patient population. Typically, patients with achondroplasia who experience knee pain are evaluated for more common and well-known etiologies such as genu varum, ligamentous instability, and neurogenic claudication. However, the authors propose that symptomatic discoid lateral meniscus should be added to the differential diagnosis for lower-extremity pain in the achondroplasia population. A thorough history and physical examination, in combination with magnetic resonance imaging, can aid in making the diagnosis. Treatment with arthroscopic debridement, saucerization of the meniscus, and repair for unstable injuries has yielded good outcomes for this patient population. [Orthopedics. 2016; 39(3):e498-e503.].

  20. Sorting waves and associated eigenvalues

    Carbonari, Costanza; Colombini, Marco; Solari, Luca

    2017-04-01

    The presence of mixed sediment always characterizes gravel bed rivers. Sorting processes take place during bed load transport of heterogeneous sediment mixtures. The two main elements necessary to the occurrence of sorting are the heterogeneous character of sediments and the presence of an active sediment transport. When these two key ingredients are simultaneously present, the segregation of bed material is consistently detected both in the field [7] and in laboratory [3] observations. In heterogeneous sediment transport, bed altimetric variations and sorting always coexist and both mechanisms are independently capable of driving the formation of morphological patterns. Indeed, consistent patterns of longitudinal and transverse sorting are identified almost ubiquitously. In some cases, such as bar formation [2] and channel bends [5], sorting acts as a stabilizing effect and therefore the dominant mechanism driving pattern formation is associated with bed altimetric variations. In other cases, such as longitudinal streaks, sorting enhances system instability and can therefore be considered the prevailing mechanism. Bedload sheets, first observed by Khunle and Southard [1], represent another classic example of a morphological pattern essentially triggered by sorting, as theoretical [4] and experimental [3] results suggested. These sorting waves cause strong spatial and temporal fluctuations of bedload transport rate typical observed in gravel bed rivers. The problem of bed load transport of a sediment mixture is formulated in the framework of a 1D linear stability analysis. The base state consists of a uniform flow in an infinitely wide channel with active bed load transport. The behaviour of the eigenvalues associated with fluid motion, bed evolution and sorting processes in the space of the significant flow and sediment parameters is analysed. A comparison is attempted with the results of the theoretical analysis of Seminara Colombini and Parker [4] and Stecca

  1. Fish communities associated with FADs

    S. Deudero

    1999-12-01

    Full Text Available Two groups of six fish aggregating devices (FADs were deployed at two locations off the eastern coast of Majorca (Western Mediterranean. Samples were obtained fortnightly throughout a two-year period by means of hauls performed with an experimental purse seine. Two control areas were established to check the aggregation efficiency of the FADs. A total of 16 families and 26 species of fishes were recorded beneath FADs. Pelagic fishes, largely Trachurus picturatus, T. mediterraneus, T. trachurus, Naucrates ductor, Seriola dumerili and Coryphaena hippurus, dominated the fauna. The total fish abundance, number of species and length range of the species confirmed that the FAD community was significantly related to season (recruitment period, resulting in a sequential fish colonisation of the FADs during the study period. Some of the species were present only during a particular period, such as Trachurus spp. in spring and summer. Other species, although evident for a longer period, were more occasional in catches (Schedophilus ovalis, Balistes carolinensis and Polyprion americanus, and some others were also present in small quantities. Diversity and equitability of the fish community associated with FADs were higher in summer than in winter. Many species were more abundant around FADs than in open water controls. The species that showed the most distinct recruitment phase beneath the FADs were N. ductor, S. ovalis, Trachurus spp., P. americanus, S. dumerili, C. hippurus and B. carolinensis. FADs can be considered nursery structures for many pelagic and demersal species, thus having an effect on the redistribution of juveniles. In the deployment of artificial structures as aggregators for fishing purposes one should consider the patchiness and seasonal characteristics of these communities as well as the redistribution aspect for fishery management.

  2. Orthopaedic injuries associated with skimboarding.

    Skimboarding is a beachside water sport that is enjoying increasing popularity among both dedicated enthusiasts and casual beachgoers. Although many consider this sport to be similar to its "sister" sport, surfing, the technique, the environment in which it is performed, and the skills required differ dramatically from that of surfing. Moreover, the pattern of injuries seen in skimboarders differs substantially from those sustained while surfing. A better understanding of the injuries encountered in this sport will allow improved participant education and facilitate the implementation of preventative measures. Descriptive epidemiology study. A case series was generated by performing a single retrospective chart review of skimboarding injuries referred for orthopaedic evaluation over a 2-year period at 2 medical treatment facilities, one on the East Coast and one on the West Coast of the United States; demographic data, injury type, and treatments rendered were documented. Sixty-one patients were identified and analyzed. Average patient age was 19.1 years. Fractures represented 93.4% of all acute injuries. The most common sites of injury were the ankle (41%) and wrist (36%). Rotation about a planted lower extremity was the most common mechanism of injury (30/61, 49%), followed by falls onto an outstretched hand (26/61, 43%). Fractures of the ankle and wrist comprise a high proportion of skimboarding injuries. Knowledge of potential hazards associated with this sport should be made available to participants. To decrease the risk of orthopaedic injury, the use of protective equipment or instruction in proper techniques of the activity may be warranted.

    2009-03-01

    Full Text Available Objective: In the last few years there has been an increase in case reports of hypernatraemic dehydration in breastfed newborns. Insufficient intake has an important role in the pathophysiology of this condition. The aim of this study was to evaluate exclusively breastfed neonates admitted for hypernatraemic dehydration. Methods: Retrospective study of breastfed neonates diagnosed with hypernatraemic dehydration, between March 2002 and March 2008, in a level 1 maternity. Rresults: Nineteen cases were identified (0.44% of neonatal intermediate care hospitalizations, 53% of them were male. The annual distribution revealed a higher number of cases in 2008: 26.3% in only three months. Median birth weight was 3,000 g and the median gestational age was 38 weeks. Vaginal delivery was the most frequent form of birth (42%, and 79% of mothers were primiparas. Admissions were made through the emergency department in 68.4%. The main reasons for seeking medical attention were: poor oral intake (32%, weight loss (26%, and jaundice (26%. The median age at admission was four days. Percentage of weight loss: 6.7 to 40%, median was 11%. Dehydration signs were absent in 42% of the patients. Median Na+ values were 152 mEq/l. Jaundice was the most frequent comorbidity found (74%. Intravenous fluids were administered in 89% and acute neurological complications were found in 21%, there were no deaths. Cconclusions: Breastfeeding-associated hypernatraemic dehydration seems to be a consequence of breastfeeding difficulties in inexperienced mothers. Since many cases are paucisymptomatic, there should be a high level of suspicion, especially in those patients with jaundice.

  4. OPATs: Omnibus P-value association tests.

    2017-07-10

    Combining statistical significances (P-values) from a set of single-locus association tests in genome-wide association studies is a proof-of-principle method for identifying disease-associated genomic segments, functional genes and biological pathways. We review P-value combinations for genome-wide association studies and introduce an integrated analysis tool, Omnibus P-value Association Tests (OPATs), which provides popular analysis methods of P-value combinations. The software OPATs programmed in R and R graphical user interface features a user-friendly interface. In addition to analysis modules for data quality control and single-locus association tests, OPATs provides three types of set-based association test: window-, gene- and biopathway-based association tests. P-value combinations with or without threshold and rank truncation are provided. The significance of a set-based association test is evaluated by using resampling procedures. Performance of the set-based association tests in OPATs has been evaluated by simulation studies and real data analyses. These set-based association tests help boost the statistical power, alleviate the multiple-testing problem, reduce the impact of genetic heterogeneity, increase the replication efficiency of association tests and facilitate the interpretation of association signals by streamlining the testing procedures and integrating the genetic effects of multiple variants in genomic regions of biological relevance. In summary, P-value combinations facilitate the identification of marker sets associated with disease susceptibility and uncover missing heritability in association studies, thereby establishing a foundation for the genetic dissection of complex diseases and traits. OPATs provides an easy-to-use and statistically powerful analysis tool for P-value combinations. OPATs, examples, and user guide can be downloaded from http://www.stat.sinica.edu.tw/hsinchou/genetics/association/OPATs.htm. © The Author 2017

    The explanation of brain functioning in terms of the association of ideas has been popular since the 17th century. Recently, however, the process of association has been dismissed as computationally inadequate by prominent cognitive scientists. In this book, a sharper definition of the term "association" is used to revive the process by showing that associative learning can indeed be computationally powerful. Within an appropriate organization, associative learning can be embodied in a robot to realize a human-like intelligence, which sets its own goals, exhibits unique unformalizable behaviou

    1991-09-01

    A hetero-association neural network using an interpattern association algorithm is presented. By using simple logical rules, hetero-association memory can be constructed based on the association between the input-output reference patterns. For optical implementation, a compact size liquid crystal television neural network is used. Translations between the English letters and the Chinese characters as well as Arabic and Chinese numerics are demonstrated. The authors have shown that the hetero-association model can perform more effectively in comparison to the Hopfield model in retrieving large numbers of similar patterns.

  12. YAGM: a web tool for mining associated genes in yeast based on diverse biological associations.

    2015-01-01

    Investigating association between genes can be used in understanding the relations of genes in biological processes. STRING and GeneMANIA are two well-known web tools which can provide a list of associated genes of a query gene based on diverse biological associations such as co-expression, co-localization, co-citation and so on. However, the transcriptional regulation association and mutant phenotype association have not been used in these two web tools. Since the comprehensive transcription factor (TF)-gene binding data, TF-gene regulation data and mutant phenotype data are available in yeast, we developed a web tool called YAGM (Yeast Associated Genes Miner) which constructed the transcriptional regulation association, mutant phenotype association and five commonly used biological associations to mine a list of associated genes of a query yeast gene. In YAGM, we collected seven kinds of datasets including TF-gene binding (TFB) data, TF-gene regulation (TFR) data, mutant phenotype (MP) data, functional annotation (FA) data, physical interaction (PI) data, genetic interaction (GI) data, and literature evidence (LE) data. Then by using the hypergeometric test to calculate the association scores of all gene pairs in yeast, we constructed seven biological associations including two transcriptional regulation associations (TFB association and TFR association), MP association, FA association, PI association, GI association, and LE association. Moreover, the expression profile association from SPELL database was also included in YAGM. When using YAGM, users can input a query gene and choose any possible subsets of the eight biological associations, then a list of associated genes of the query gene will be returned based on the chosen biological associations. In this study, we presented the YAGM which provides eight biological associations for mining associated genes of a query gene in yeast. Among the eight biological associations constructed in YAGM, three (TFB

    Understanding the relationship between diseases based on the underlying biological mechanisms is one of the greatest challenges in modern biology and medicine. Exploring disease-disease associations by using system-level biological data is expected to improve our current knowledge of disease relationships, which may lead to further improvements in disease diagnosis, prognosis and treatment. We took advantage of diverse biological data including disease-gene associations and a large-scale molecular network to gain novel insights into disease relationships. We analysed and compared four publicly available disease-gene association datasets, then applied three disease similarity measures, namely annotation-based measure, function-based measure and topology-based measure, to estimate the similarity scores between diseases. We systematically evaluated disease associations obtained by these measures against a statistical measure of comorbidity which was derived from a large number of medical patient records. Our results show that the correlation between our similarity measures and comorbidity scores is substantially higher than expected at random, confirming that our similarity measures are able to recover comorbidity associations. We also demonstrated that our predicted disease associations correlated with disease associations generated from genome-wide association studies significantly higher than expected at random. Furthermore, we evaluated our predicted disease associations via mining the literature on PubMed, and presented case studies to demonstrate how these novel disease associations can be used to enhance our current knowledge of disease relationships. We present three similarity measures for predicting disease associations. The strong correlation between our predictions and known disease associations demonstrates the ability of our measures to provide novel insights into disease relationships.

    A novel framework for mining temporal association rules by discovering itemsets with a genetic algorithm is introduced. Metaheuristics have been applied to association rule mining, we show the efficacy of extending this to another variant - temporal association rule mining. Our framework is an enhancement to existing temporal association rule mining methods as it employs a genetic algorithm to simultaneously search the rule space and temporal space. A methodology for validating the ability of the proposed framework isolates target temporal itemsets in synthetic datasets. The Iterative Rule Learning method successfully discovers these targets in datasets with varying levels of difficulty.

All cases of chronic gastritis with Helicobacter infection were evaluated with the Updated Sydney System, and the grades of all gastritis variables were compared between H. heilmannii-associated gastritis and H. pylori-associated gastritis groups. There were 10 cases of H. heilmannii-associated gastritis (0.17%) and 3,285 cases of H. pylori-associated gastritis (54.9%). The organisms were superficially located within the mucous layer without adhesion to epithelial cells. Interestingly, in one case many intracytoplasmic H. heilmannii organisms were observed in parietal cells with cell damage. A case of low-grade mucosa-associated lymphoid tissue (MALT) lymphoma concomitant with H. heilmannii infection was detected. Compared to H. pylori-associated gastritis, H. heilmannii-associated gastritis showed less severe neutrophilic activity (pgastritis devoid of erosion or ulcer (p=0.0309). In conclusion, we present the detailed clinicopathologic findings of H. heilmannii-associated gastritis compared to H. pylori-associated gastritis. H. heilmannii-associated gastritis is uncommon and milder than H. pylori-associated gastritis, however it may be noteworthy with respect to the development of MALT lymphoma. PMID:17297253

    There is evidence of association between systemic diseases and oral conditions, although it is not clear if these are direct or mediated by underlying factors such as health behaviors. The aim of this work was to evaluate whether self-reported systemic diseases were associated with caries experience. Medical history data and caries experience (DMFT and DMFS; Decayed, Missing due to caries, Filled Teeth/Surface) were obtained from the University of Pittsburgh School of Dental Medicine Dental Registry and DNA Repository. Information on 318 subjects (175 females and 143 males) was evaluated. Regression analysis was used to test for association between caries experience and disease status. The stronger associations were found between caries experience and asthma and epilepsy. With respect to asthma, DMFT above 15 (R(2) = 0.04) and DMFS above 50 (R(2) = 0.02) were associated. After controlling for gender differences in asthma, the associations remained strong (R(2) = 0.05 for both DMFT and DMFS). For epilepsy, DMFT above 15 (R(2) = 0.18) and DMFS above 50 (R(2) = 0.14) were associated. Asthma and epilepsy are associated with higher caries experience.

    Preeclampsia complicates 2-8% of all pregnancies. Studies on the association of preeclampsia with thrombophilia are conflicting. Clinical heterogeneity of the disease may be one of the explanations. The present study addresses the question whether different phenotypes of preeclampsia are associated with thrombophilia factors. Study design We planned a retrospective cohort study. From 1985 until 2010 women with preeclampsia were offered postpartum screening for the following thrombophilia factors: anti-phospholipid antibodies, APC-resistance, protein C deficiency and protein S deficiency, hyperhomocysteineamia, factor V Leiden and Prothrombin gene mutation. Hospital records were used to obtain information on phenotypes of the preeclampsia and placental histology. We identified 844 women with singleton pregnancies who were screened for thrombophilia factors. HELLP complicated 49% of pregnancies; Fetal growth restriction complicated 61% of pregnancies. Early delivery (preeclampsia was associated with protein S deficiency (p=0.01). Fetal growth restriction was associated with anti-phospholipid antibodies (ppreeclampsia was associated with anti-phospholipid antibodies (p=0.01). Extensive placental infarction (>10%) was associated with anti-phospholipid antibodies (ppreeclampsia, especially if complicated by fetal growth restriction, are associated with anti-phospholipid antibodies. Other phenotypes of preeclampsia, especially HELLP syndrome, were not associated with thrombophilia. We advise only to test for anti-phospholipid antibodies after early onset preeclampsia, especially if complicated by fetal growth restriction. We suggest enough evidence is presented to justify no further studies are needed. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Objective The objective of this study was to investigate the association of lupus nephritis on organ damage and mortality in patients with systemic lupus erythematosus (SLE). Methods A total of 1112 patients with SLE were investigated. Lupus nephritis was defined as a proteinuria based on the 1997 American College of Rheumatology criteria. Damage was assessed using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index. The associations of lupus nephritis with overall, non-renal, corticosteroid-associated, and non-associated damage were analyzed using logistic regression. The age-adjusted and sex-adjusted standardized mortality ratio was evaluated in patients with and without lupus nephritis. Results The prevalence of lupus nephritis in patients with SLE was 46.3%. Patients with lupus nephritis had a higher percentage of overall cumulative damage than patients without lupus nephritis (51.5% vs. 35.7%, p lupus nephritis. The standardized mortality ratios of patients with and without lupus nephritis were 5.17 (95% CI 3.49-7.38) and 2.32 (95% CI 1.47-3.48), respectively. Conclusion In patients with SLE, the presence of lupus nephritis is associated with increased corticosteroid-associated damage but less corticosteroid non-associated damage. Also, mortality is significantly higher in patients with lupus nephritis than in those without lupus nephritis.

    Conroy, Melissa J; Dunne, Margaret R; Donohoe, Claire L; Reynolds, John V

    2016-05-01

    Epidemiological studies have established an association between obesity, insulin resistance, type 2 diabetes and a number of cancer types. Research has focused predominantly on altered endocrine factors, growth factors and signalling pathways, with little known in man about the immune involvement in the relevant pathophysiological processes. Moreover, in an era of exciting new breakthroughs in cancer immunotherapy, there is also a need to study the safety and efficacy of immunotherapeutics in the complex setting of inflammatory-driven obesity-associated cancer. This review addresses key immune cell subsets underpinning obesity-associated inflammation and describes how such immune compartments might be targeted to prevent and treat obesity-associated cancer. We propose that the modulation, metabolism, migration and abundance of pro- and anti-inflammatory cells and tumour-specific T cells might be therapeutically altered to both restore immune balance, alleviating pathological inflammation, and to improve anti-tumour immune responses in obesity-associated cancer.

    Summary of “Extension of association models to complex chemicals”. Ph.D. thesis by Ane Søgaard Avlund The subject of this thesis is application of SAFT type equations of state (EoS). Accurate and predictive thermodynamic models are important in many industries including the petroleum industry....... The SAFT EoS was developed 20 years ago, and a large number of papers on the subject has been published since, but many issues still remain unsolved. These issues are both theoretical and practical. The SAFT theory does not account for intramolecular association, it can only treat flexible chains, and does...... functional groups. It is also tested whether increasing the number of sites for DEA (diethanolamine) improves the results. It can be shown from experimental data that intramolecular association is dominating compared to intermolecular association in certain systems, and that the intramolecular association...

The means of the Association to realize its aims are described in Article I.1.3 of the Statutes of the CERN Staff Association. Generally speaking, its aims are “To serve and defend the economic, social, professional and moral interests of its members and all CERN staff“. Usually we deal with professional and social issues (employment conditions, defence of collective or individual rights, promotion of basic research...). But the Association also plays a role of integration (clubs promoting cultural, humanitarian, and sport or offering entertainment, organizing exhibitions and conferences) and it can promote actions to provide its members with material or social advantages (Interfon, commercial offers).

    Previous reports have described several associations of PR, QRS, QT and heart rate with genomic variations by genome-wide association studies (GWASs). In the present study, we examined the association of ∼2.5 million SNPs from 2994 Japanese healthy volunteers obtained from the JPDSC database with electrocardiographic parameters. We confirmed associations of PR interval, QRS duration and QT interval in individuals of Japanese ancestry with 11 of the 45 SNPs (6 of 20 for QT, 5 of 19 for PR and 0 of 6 for QRS) observed among individuals of European, African and Asian (Indian and Korean) ancestries. Those results indicate that many of the electrocardiographic associations with genes are shared by different ethnic groups including Japanese. Possible novel associations found in this study were validated by Korean data. As a result, we identified a novel association of SNP rs4952632[G] (maps near SLC8A1, sodium-calcium exchanger) (P = 7.595 × 10(-6)) with PR interval in Japanese individuals, and replication testing among Koreans confirmed the association of the same SNP with prolonged PR interval. Meta-analysis of the Japanese and Korean datasets demonstrated highly significant associations of SNP rs4952632[G] with a 2.325-ms (95% CI, 1.693-2.957 ms) longer PR interval per minor allele copy (P = 5.598 × 10(-13)). Cell-type-specific SLC8A1 knockout mice have demonstrated a regulatory role of sodium-calcium exchanger in automaticity and conduction in sinoatrial node, atrium and atrioventricular node. Our findings support a functional role of sodium-calcium exchanger in human atrial and atrioventricular nodal conduction as suggested by genetically modified mouse models. © The Author 2014.

  14. The association between oxytocin and social capital.

    Directory of Open Access Journals (Sweden)

    Takeo Fujiwara

    Full Text Available BACKGROUND: Oxytocin is known to be related to social behaviors, including trust. However, few studies have investigated the association between oxytocin levels and social capital. Thus, we tested the hypothesis that endogenous oxytocin levels are positively associated with social capital. We also considered whether the association differed across gender because previous studies have shown differential effects of OT on social behaviors depending on gender. METHODS: We recruited a convenience sample of 50 women and 31 men in Japan via community sampling from whom we obtained urine sample with which to measure oxytocin levels. Individual-level cognitive social capital (social trust and mutual aid and structural social capital (community participation were assessed using a questionnaire. We used multivariate regression, adjusted for covariates (age, number of children, self-rated health, and education, and stratified by gender to consider associations between oxytocin and social capital. RESULTS: Among women, oxytocin was inversely associated with social trust and mutual aid (p<0.05. However, women participating in only 1 organization in the community showed higher oxytocin than women who participated in either no organizations (p<0.05 or 2 or more organization (i.e. inverse-U shape association. Among men, no association was observed between oxytocin and either form of cognitive and structural social capital. CONCLUSION: Women who perceived low cognitive social capital showed higher oxytocin levels, while structural social capital showed inverse-U shape association with oxytocin. No association between oxytocin and social capital was found among men. Further study is needed to elucidate why oxytocin was inversely associated with cognitive social capital only among women.

  15. Prefrontal Dopamine in Associative Learning and Memory

    2014-01-01

    Learning to associate specific objects or actions with rewards and remembering the associations are everyday tasks crucial for our flexible adaptation to the environment. These higher-order cognitive processes depend on the prefrontal cortex (PFC) and frontostriatal circuits that connect areas in the frontal lobe with the striatum in the basal ganglia. Both structures are densely innervated by dopamine (DA) afferents that originate in the midbrain. Although the activity of DA neurons is thought to be important for learning, the exact role of DA transmission in frontostriatal circuits during learning-related tasks is still unresolved. Moreover, the neural substrates of this modulation are poorly understood. Here, we review our recent work in monkeys utilizing local pharmacology of DA agents in the PFC to investigate the cellular mechanisms of DA modulation of associative learning and memory. We show that blocking both D1 and D2 receptors in the lateral PFC impairs learning of new stimulus-response associations and cognitive flexibility, but not the memory of highly familiar associations. In addition, D2 receptors may also contribute to motivation. The learning deficits correlated with reductions of neural information about the associations in PFC neurons, alterations in global excitability and spike synchronization, and exaggerated alpha and beta neural oscillations. Our findings provide new insights into how DA transmission modulate associative learning and memory processes in frontostriatal systems. PMID:25241063

    To identify MRI features associated with appendicitis. Features expected to be associated with appendicitis were recorded in consensus by two expert radiologists on 223 abdominal MRIs in patients with suspected appendicitis. Nine MRI features were studied: appendix diameter >7 mm, appendicolith, peri-appendiceal fat infiltration, peri-appendiceal fluid, absence of gas in the appendix, appendiceal wall destruction, restricted diffusion of the appendiceal wall, lumen or focal fluid collections. Appendicitis was assigned as the final diagnosis in 117/223 patients. Associations between imaging features and appendicitis were evaluated with logistic regression analysis. All investigated features were significantly associated with appendicitis in univariate analysis. Combinations of two and three features were associated with a probability of appendicitis of 88 % and 92 %, respectively. In patients without any of the nine features, appendicitis was present in 2 % of cases. After multivariate analysis, only an appendix diameter >7 mm, peri-appendiceal fat infiltration and restricted diffusion of the appendiceal wall were significantly associated with appendicitis. The probability of appendicitis was 96 % in their presence and 2 % in their absence. An appendix diameter >7 mm, peri-appendiceal fat infiltration and restricted diffusion of the appendiceal wall have the strongest association with appendicitis on MRI. (orig.)

  17. Association of TCTP with Centrosome and Microtubules

    Full Text Available Translationally Controlled Tumour Protein (TCTP associates with microtubules (MT, however, the details of this association are unknown. Here we analyze the relationship of TCTP with MTs and centrosomes in Xenopus laevis and mammalian cells using immunofluorescence, tagged TCTP expression and immunoelectron microscopy. We show that TCTP associates both with MTs and centrosomes at spindle poles when detected by species-specific antibodies and by Myc-XlTCTP expression in Xenopus and mammalian cells. However, when the antibodies against XlTCTP were used in mammalian cells, TCTP was detected exclusively in the centrosomes. These results suggest that a distinct pool of TCTP may be specific for, and associate with, the centrosomes. Double labelling for TCTP and γ-tubulin with immuno-gold electron microscopy in Xenopus laevis oogonia shows localization of TCTP at the periphery of the γ-tubulin-containing pericentriolar material (PCM enveloping the centriole. TCTP localizes in the close vicinity of, but not directly on the MTs in Xenopus ovary suggesting that this association requires unidentified linker proteins. Thus, we show for the first time: (1 the association of TCTP with centrosomes, (2 peripheral localization of TCTP in relation to the centriole and the γ-tubulin-containing PCM within the centrosome, and (3 the indirect association of TCTP with MTs.

    We tackle the problem of finding regularities in microarray data. Various data mining tools, such as clustering, classification, Bayesian networks and association rules, have been applied so far to gain insight into gene-expression data. Association rule mining techniques used so far work on discretizations of the data and cannot account for cumulative effects. In this paper, we investigate the use of quantitative association rules that can operate directly on numeric data and represent cumulative effects of variables. Technically speaking, this type of quantitative association rules based on half-spaces can find non-axis-parallel regularities. We performed a variety of experiments testing the utility of quantitative association rules for microarray data. First of all, the results should be statistically significant and robust against fluctuations in the data. Next, the approach should be scalable in the number of variables, which is important for such high-dimensional data. Finally, the rules should make sense biologically and be sufficiently different from rules found in regular association rule mining working with discretizations. In all of these dimensions, the proposed approach performed satisfactorily. Therefore, quantitative association rules based on half-spaces should be considered as a tool for the analysis of microarray gene-expression data. The code is available from the authors on request.

  19. Exploiting Genome Structure in Association Analysis

    Kim, Seyoung

    2014-01-01

    Abstract A genome-wide association study involves examining a large number of single-nucleotide polymorphisms (SNPs) to identify SNPs that are significantly associated with the given phenotype, while trying to reduce the false positive rate. Although haplotype-based association methods have been proposed to accommodate correlation information across nearby SNPs that are in linkage disequilibrium, none of these methods directly incorporated the structural information such as recombination events along chromosome. In this paper, we propose a new approach called stochastic block lasso for association mapping that exploits prior knowledge on linkage disequilibrium structure in the genome such as recombination rates and distances between adjacent SNPs in order to increase the power of detecting true associations while reducing false positives. Following a typical linear regression framework with the genotypes as inputs and the phenotype as output, our proposed method employs a sparsity-enforcing Laplacian prior for the regression coefficients, augmented by a first-order Markov process along the sequence of SNPs that incorporates the prior information on the linkage disequilibrium structure. The Markov-chain prior models the structural dependencies between a pair of adjacent SNPs, and allows us to look for association SNPs in a coupled manner, combining strength from multiple nearby SNPs. Our results on HapMap-simulated datasets and mouse datasets show that there is a significant advantage in incorporating the prior knowledge on linkage disequilibrium structure for marker identification under whole-genome association.

  1. Associations among homesickness, anger, anxiety, and depression.

    2004-06-01

    The study investigated the association of homesickness with the related concepts of anxiety, depression, and anger. Two conceptualizations of homesickness were used, one considering homesickness as a state, characterized by severe symptoms of a depressive episode, and the other one as a self-reported tendency to experience homesickness in times of separation from the familiar environment. The latter conceptualization can rather be considered as an enduring trait and does not specifically refer to actual feelings of depression. We compared these two conceptualizations of homesickness in a random sample from the Dutch population (n=485) by assessing their uni- and multivariate associations with anger, anxiety, depression, and anxiety-sensitivity. Both conceptualizations of homesickness were associated with anxiety and depression and with the externalization of anger. No association was found between internalization of anger or control over internalized and externalized anger for either conceptualization of homesickness. The pattern of multivariate associations between homesickness and its emotional correlates was similar for both conceptualizations, although homesickness as a state appeared to have a stronger association with depression, whereas the tendency to develop homesickness showed a particularly strong association with anxiety. It is concluded that homesickness can be considered as a mixed emotion of anxiety and depression ("Cothymia"), but that depression is more characteristic of homesickness as a state, whereas anxiety is more important if homesickness is conceptualized as an enduring tendency.

  2. Metagenomic Guilt by Association: An Operonic Perspective

    2013-01-01

    Next-generation sequencing projects continue to drive a vast accumulation of metagenomic sequence data. Given the growth rate of this data, automated approaches to functional annotation are indispensable and a cornerstone heuristic of many computational protocols is the concept of guilt by association. The guilt by association paradigm has been heavily exploited by genomic context methods that offer functional predictions that are complementary to homology-based annotations, thereby offering a means to extend functional annotation. In particular, operon methods that exploit co-directional intergenic distances can provide homology-free functional annotation through the transfer of functions among co-operonic genes, under the assumption that guilt by association is indeed applicable. Although guilt by association is a well-accepted annotative device, its applicability to metagenomic functional annotation has not been definitively demonstrated. Here a large-scale assessment of metagenomic guilt by association is undertaken where functional associations are predicted on the basis of co-directional intergenic distances. Specifically, functional annotations are compared within pairs of adjacent co-directional genes, as well as operons of various lengths (i.e. number of member genes), in order to reveal new information about annotative cohesion versus operon length. The results suggests that co-directional gene pairs offer reduced confidence for metagenomic guilt by association due to difficulty in resolving the existence of functional associations when intergenic distance is the sole predictor of pairwise gene interactions. However, metagenomic operons, particularly those with substantial lengths, appear to be capable of providing a superior basis for metagenomic guilt by association due to increased annotative stability. The need for improved recognition of metagenomic operons is discussed, as well as the limitations of the present work. PMID:23940763

    Biofilms are structured groups of different bacterial species that are responsible for most chronic and recurrent infections. Biofilm-related infections reoccur in approximately 65-80% of cases. Bacteria associated with the biofilm are highly resistant to antibiotics. Knowledge of biofilm formation, its propagation and the resistance associated with it is scant and a multidisciplinary approach is followed to understand the science and develop strategies to address this problem. This article discusses the role of various biochemical factors, molecular mechanisms and altered host environment causes associated with bacterial resistance in biofilm. It also reveals the target sites and different multidisciplinary strategies adapted for destroying or preventing the formation of biofilms.

    2001-01-01

    Kaposi's Sarcoma associated Herpesvirus (KSHV) is the most recently discovered human tumor virus and is associated with the pathogenesis of Kaposi's sarcoma, primary effusion lymphoma, and Multicentric Casttleman's disease. KSHV contains numerous open reading frames with striking homology to cellular genes. These viral gene products play a variety of roles in KSHV-associated pathogenesis by disrupting cellular signal transduction pathways, which include interferon-mediated anti-viral responses, cytokine-regulated cell growth, apoptosis, and cell cycle control. In this review, we will attempt to cover our understanding of how viral proteins deregulate cellular signaling pathways, which ultimately contribute to the conversion of normal cells to cancerous cells.

    2012-02-03

    Autoimmune hepatitis is a rare, chronic inflammatory disorder which has been associated with a number of other auto-immune conditions. However, there are no reports in the medical literature of an association with microscopic (lymphocytic) colitis. We report the case of a 53-year-old woman with several autoimmune conditions, including lymphocytic colitis, who presented with an acute hepatitis. On the basis of the clinical features, serology, and histopathology, we diagnosed autoimmune hepatitis. To our knowledge, this is the first report of autoimmune hepatitis in association with lymphocytic colitis, and lends support to the theory of an autoimmune etiology for lymphocytic colitis.

    The metaphase of 21 severely mentally retarded patients were studies to assess the role of satellite association in the etiology of mental retardation. Peripheral blood culture, chromosome harvesting and study scoring were conducted according to standard methods. Considered as a whole the results indicate that there is a significant increase in the frequency of satellite association among the mentally retarded. The present study concluded that satellite association may play a role in the etiology of mental retardation and may explain to some extent the presence of normal karyotype in some mental retardation patients.

    Castleman disease can occur in association with autoimmune connective tissue disease and confound the clinical picture, resulting in delayed diagnosis and suboptimal treatment. This review focuses on the intersection of Castleman disease and autoimmunity with an emphasis on shared pathology and mutually beneficial treatments. Targeting CD-20, interleukin-6, and the nuclear factor-κB pathway has shown promise in achieving long-term remission in patients with Castleman disease and associated autoimmune features. Advances in understanding of pathogenic cell types and cytokines in Castleman disease have allowed the development of targeted therapies successful in the treatment of both Castleman disease and associated autoimmune disease.

    Cancer patients are commonly affected by cachexia, a wasting process involving muscle and fat. Specifically, loss of the muscle compartment has been associated with poor prognosis and suboptimal response to therapy. Nutritional support has been ineffective in treating this process leading to investigations into the underlying molecular processes governing muscle catabolism. In this commentary, we discuss the molecular mechanisms of cancer-associated muscle metabolism and the epigenetic processes responsible for the muscle wasting phenotype. Ultimately, we highlight how the epigenome may serve as a promising therapeutic target in reversing cancer-associated muscle catabolism.

    2011-01-01

    Heterotopia is a subgroup of migration abnormalities, recognized by arrest of radial migration of neuroblasts. Being a well-known cause for developmental delay, mental retardation, and epilepsy, association of heterotopia with some other conditions has also been proposed. There are several case reports regarding the concurrence of heterotopia and encephalocele; however, no such association has been reported with cervical meningocele. Herein, we present the first case of periventricular nodular heterotopia associated with cervical meningocele. Our case further emphasizes the role of brain MRI in the evaluation of those with neural tube defects. Recognition of possible associated heterotopia is important for planning proper treatment and genetic counseling. Copyright © 2011 Elsevier Inc. All rights reserved.

    2008-07-01

    Segmental neurofibromatosis (SN) is a rare disorder characterized by neurofibromas or neurofibromas with café-au-lait spots limited to one region of the body without crossing the midline. Renal angiomyolipomas (AMLs) are rare benign neoplasms usually found in association with tuberous sclerosis (TS). Similar to neurofibromatosis (NF), TS has a high spontaneous mutation rate and a family history often is absent. Although both are autosomal dominant diseases with neural involvement, there are few reports in the literature demonstrating a link between the 2 disorders. We report a case of SN associated with renal AMLs. To our knowledge, there has been only 1 prior report of renal AML associated with NF type 1 (NF1), and there have been no prior reports of SN associated with AML.

  16. Awake, Offline Processing during Associative Learning.

    Directory of Open Access Journals (Sweden)

    James K Bursley

    Full Text Available Offline processing has been shown to strengthen memory traces and enhance learning in the absence of conscious rehearsal or awareness. Here we evaluate whether a brief, two-minute offline processing period can boost associative learning and test a memory reactivation account for these offline processing effects. After encoding paired associates, subjects either completed a distractor task for two minutes or were immediately tested for memory of the pairs in a counterbalanced, within-subjects functional magnetic resonance imaging study. Results showed that brief, awake, offline processing improves memory for associate pairs. Moreover, multi-voxel pattern analysis of the neuroimaging data suggested reactivation of encoded memory representations in dorsolateral prefrontal cortex during offline processing. These results signify the first demonstration of awake, active, offline enhancement of associative memory and suggest that such enhancement is accompanied by the offline reactivation of encoded memory representations.

    Full Text Available Abstract Background We investigated how temporal context affects the learning of arbitrary visuo-motor associations. Human observers viewed highly distinguishable, fractal objects and learned to choose for each object the one motor response (of four that was rewarded. Some objects were consistently preceded by specific other objects, while other objects lacked this task-irrelevant but predictive context. Results The results of five experiments showed that predictive context consistently and significantly accelerated associative learning. A simple model of reinforcement learning, in which three successive objects informed response selection, reproduced our behavioral results. Conclusions Our results imply that not just the representation of a current event, but also the representations of past events, are reinforced during conditional associative learning. In addition, these findings are broadly consistent with the prediction of attractor network models of associative learning and their prophecy of a persistent representation of past objects.

    The occupational stress is associated with dissatisfaction, excessive demand at work and personal factors. Those factors can reduce work performance and can predispose workers to various diseases. Workers' health may be protected if there is encouragement to face challenges, which may lessen the impact on psychological and somatic stress and thus have greater personal and professional satisfaction. The aim of this study was to evaluate the association between occupational stress and work engagement. Participated in this study 457 male and female workers of a metallurgical industry. Subjects answered personal data, and the Job Stress Scale and Utrecht Work Engagement Scale were applied. Results showed an association between occupational stress and work engagement (P=0,001). The way the individual deals with his frustrations, or rather the work engagement, is associated with the occupational stress.

    Full Text Available Abstract Background Kocuria, previously classified into the genus of Micrococcus, is commonly found on human skin. Two species, K. rosea and K. kristinae, are etiologically associated with catheter-related bacteremia. Case presentation We describe the first case of K. kristinae infection associated with acute cholecystitis. The microorganism was isolated from the bile of a 56-year old Chinese man who underwent laparoscopic cholecystectomy. He developed post-operative fever that resolved readily after levofloxacin treatment. Conclusion Our report of K. kristinae infection associated with acute cholecystitis expands the clinical spectrum of infections caused by this group of bacteria. With increasing number of recent reports describing the association between Kocuria spp. and infectious diseases, the significance of their isolation from clinical specimens cannot be underestimated. A complete picture of infections related to Kocuria spp. will have to await the documentation of more clinical cases.

    Aljenedil, Sumayah; Hegele, Robert A; Genest, Jacques; Awan, Zuhier

    Estrogen, whether therapeutic or physiologic, can cause hypertriglyceridemia. Hypertriglyceridemia-induced pancreatitis is a rare complication. We report 2 women who developed estrogen-associated severe hypertriglyceridemia with pancreatitis. The first patient developed pancreatitis secondary to hypertriglyceridemia associated with in vitro fertilization cycles. Marked reduction in her triglyceride was achieved with dietary restrictions and fibrate. The second patient developed pancreatitis secondary to hypertriglyceridemia during her pregnancies. She was noncompliant with the treatment; therefore, her triglyceride remained high after delivery. In both patients, no hypertriglyceridemia-associated genes mutations were identified, although the second patient had strong polygenic susceptibility to hypertriglyceridemia. Estrogen-induced severe hypertriglyceridemia with pancreatitis can be a life-threatening condition. Screening in high-risk patients is crucial to prevent subsequent complications.

    Full Text Available Turner syndrome (TS is a rare genetic disease due to the absence of one X chromosome. Patients with TS have more subtle neurological/neuropsychiatric problems, while headache is an uncommon clinical presentation which needs attention. We report a 12-year-old child presenting with typical cough headache. Her magnetic resonance imaging revealed Chiari I malformation associated with TS. To the best of our knowledge, Chiari I malformation associated with TS is not described in literature. We report the first case of TS associated with Chiari I malformation. Interestingly, Chiari I malformation is also associated with Noonan's syndrome, which is a close morphological mimicker of TS, raising the possibility of sharing similar pathogenesis in both conditions.

    Trinary associative memory combines merits and overcomes major deficiencies of unipolar and bipolar logics by combining them in three-valued logic that reverts to unipolar or bipolar binary selectively, as needed to perform specific tasks. Advantage of associative memory: one obtains access to all parts of it simultaneously on basis of content, rather than address, of data. Consequently, used to exploit fully parallelism and speed of optical computing.

    2012-12-01

    Cam-type, pincer, and mixed femoroacetabular impingement (FAI) are accepted causes of labral and acetabular rim injury; however, the abnormal contact stresses associated with motion may damage other areas of the hip. Although cartilage damage to the femoral head has been reported previously in athletes, FAI-associated focal parafoveal chondral defects differ from previously reported lesions and represent a rare manifestation of the complex pathomechanics associated with FAI. We describe the clinical, radiographic, and surgical characteristics of a rare focal anterolateral parafoveal femoral chondral defect associated with FAI. We retrospectively reviewed 10 patients with symptomatic FAI diagnosed with this unique focal defect confirmed at the time of surgical dislocation. Patients presented with hip pain, clinical findings of FAI, and, frequently, with an identifiable lesion on MRI arthrography. The minimum clinical followup was 12 months (mean, 29 months; range, 12-72 months). The consistent characteristics of these lesions associated with FAI differ from previously reported femoral chondral damage reported after hip dislocation or lateral impact in that there was no discrete injury such as a fall or dislocation/subluxation, no associated traumatic femoral lesion, and all were localized to the posterosuperior femoral head. Eight of 10 were diagnosed preoperatively using MR arthrography. Despite radiographic similarities to findings of osteoarthritis and osteonecrosis, these FAI-associated femoral chondral defects were amenable to surgical reconstruction using first- or second-generation cartilage repair techniques during surgical treatment of impingement. The etiology of these lesions may be related to complex intraarticular forces generated by FAI-associated transient hip subluxation or forceful nonconcentric motion. Level IV, therapeutic study.

    Urinary incontinence (UI) and sexual dysfunction are common conditions often undiagnosed and untreated in women and are associated with decreased quality of life. To evaluate the relation between UI and female sexual dysfunction (FSD), considering incontinence type and the psychosocial and physiologic aspects of sexual function. PubMed search of terms related to UI and FSD from 1979 to 2016 generated 603 published references, of which 26 were included. Nine additional studies came from bibliographic review. Rates and types of sexual dysfunction. In cross-sectional and case-control studies, UI was associated with increased rates and severity of FSD. Coital UI occurred in 24% to 66% of women with UI. Impaired body image, fear of coital UI, avoidance of sex, and complete abstinence were more common in women with UI. Deficits in desire, lubrication, satisfaction, and increased pain were found across numerous studies. Mixed UI was associated with more FSD than urgency UI and stress UI. Multiple studies suggest urgent UI is more bothersome than stress UI. Coital UI was associated with a urodynamic diagnosis other than genuine stress incontinence in 25% to 50%. Leakage at penetration was associated with stress UI; leakage at orgasm was associated more often with detrusor overactivity. Women's UI is associated with increased rates of sexual dysfunction, suggesting concurrent screening is warranted. Clarifying timing of coital leakage would facilitate targeted treatment. Standardization of FSD measurements could better elucidate the relation between UI and FSD. Duralde ER, Rowen TS. Urinary Incontinence and Associated Female Sexual Dysfunction.

    Full Text Available Retroperitoneal fibrosis is an uncommon disease that often presents in a subtle manner. Only a few cases of the combined association of generalized atherosclerosis and retroperitoneal fibrosis are reported in the recent literature, supporting the view that the condition is probably an autoimmune periaortitis. We describe a typical case of retroperitoneal fibrosis associated with generalized atherosclerosis with clinical presentation of progressive renal insufficiency, and claudication from arterial compromise.

    2010-01-01

    Infective endocarditis caused by Streptococcus bovis is known to be associated with colorectal malignancy. Other less common streptococci, specifically Streptococcus sanguis, can be similarly associated with gastrointestinal carcinoma. We present a case of disseminated colorectal carcinoma occurring after a confirmed S sanguis endocarditis, that required mitral valve surgery. There may be a need for gastrointestinal surveillance in patients presenting with bacteraemia caused by less common streptococci.

    Amyloid-associated cystic lung disease is rare. It can be associated with collagen vascular disease (CVD). We aimed to describe the clinical, radiology, and pathology findings of this entity. We reviewed the records of subjects having biopsy-proven pulmonary amyloidosis with cystic lung disease demonstrated at high-resolution computed tomography (HRCT). Demographic characteristics, association with CVD and lymphoproliferative disorders, pulmonary function, and pathology results were reviewed. HRCT appearance was analyzed for number, size, distribution, and morphology of cysts and nodules. Twenty-one subjects (13 female, eight male; median age, 61 years) with cystic pulmonary amyloidosis were identified. The most common pulmonary function patterns were normal (42%) and obstructive (32%). The most common associated CVD was Sjögren syndrome (10 of 12). Nine subjects had no CVD. Cysts tended to be multiple (≥ 10 in 14 of 21, 67%), round (21 of 21, 100%), or lobulated (20 of 21, 95%); thin-walled (cystic lung disease can occur with or without underlying CVD. Cystic lesions in the lung are commonly numerous, often are peribronchovascular or subpleural, and are frequently associated with nodular lesions that are often calcified. MALToma was a relatively frequent association. Copyright © 2016 American College of Chest Physicians. Published by Elsevier Inc. All rights reserved.

  4. Semantic and associative priming in picture naming.

    Alario, F X; Segui, J; Ferrand, L

    2000-08-01

    We report four picture-naming experiments in which the pictures were preceded by visually presented word primes. The primes could either be semantically related to the picture (e.g., "boat"--TRAIN: co-ordinate pairs) or associatively related (e.g., "nest"--BIRD: associated pairs). Performance under these conditions was always compared to performance under unrelated conditions (e.g., "flower"--CAT). In order to distinguish clearly the first two kinds of prime, we chose our materials so that (a) the words in the co-ordinate pairs were not verbally associated, and (b) the associate pairs were not co-ordinates. Results show that the two related conditions behaved in different ways depending on the stimulus-onset asynchrony (SOA) separating word and picture appearance, but not on how long the primes were presented. When presented with a brief SOA (114 ms, Experiment 1), the co-ordinate primes produced an interference effect, but the associated primes did not differ significantly from the unrelated primes. Conversely, with a longer SOA (234 ms, Experiment 2) the co-ordinate primes produced no effect, whereas a significant facilitation effect was observed for associated primes, independent of the duration of presentation of the primes. This difference is interpreted in the context of current models of speech production as an argument for the existence, at an automatic processing level, of two distinguishable kinds of meaning relatedness.

    2018-03-01

    Preeclampsia is a complex genetic disorder with an incompletely understood pathogenesis. Its phenotype may be better elucidated by integrating symptoms. This study aimed to identify symptoms by gestational age and associations with novel preeclampsia candidate genes. Women with a history of preeclampsia recruited from The Preeclampsia Registry completed clinical/demographic, symptom surveys and provided medical records. DNA extracted from saliva was processed with multiplexed assays for eight single-nucleotide polymorphisms (SNPs) selected to tag candidate genes and/or located in symptom susceptibility regions. Groups with versus without symptoms were compared using χ 2 . Associations between SNPs and symptoms were analyzed as genotype categories and presence/absence of the variant allele. Logistic regression modeling was conducted with exploratory p = .05. In 114 participants, 113 reported at least 1 of the 18 symptoms. Symptoms varied by trimester. Nine symptoms were associated with seven SNPs. Visual disturbances were associated with three SNPs and nausea/vomiting with two SNPs. Modeling adjustment for maternal age and parity resulted in 15 associations between 9 symptoms and 8 SNPs. Medical records demonstrated 100% concordance with self-reported diagnosis and 48% concordance with reported severity. Findings indicated novel symptom-genotype associations in preeclampsia. The small sample was self-selected, but results support future studies including medical records review. When validated, these results may lead to holistic phenotyping of women to characterize subsets of preeclampsia. This approach may optimize health in pregnancy and later life for mothers and offspring through prediction, prevention, and precision nursing care.

  6. PATIENT SAFETY AND HEALTHCARE-ASSOCIATED INFECTIONS

    2011-04-01

    Full Text Available Healthcare-associated infections are infections caused by a wide variety of common and unusual bacteria, fungi, and viruses during the course of receiving medical care. Medical advances have brought lifesaving care to patients in need, yet many of those advances come with a risk of healthcare-associated infection. These infections related to medical care can be devastating and even deadly. As the ability to prevent healthcare-associated infections grows, these infections are increasingly unacceptable.Recent successes in healthcare-associated infections elimination have been very encouraging. Examples include sustained reduction in central line-associated bloodstream infections by 70%, simply by ensuring adherence to available guidelines. Reductions have been demonstrated for other helthcare-associated infections as well, but, much more remains to be done.Wherever patient care is provided, adherence to infection prevention guidelines is needed to ensure that all care is safe care. This includes traditional hospital settings as well as outpatient surgery centers, long-term care facilities, rehabilitation centers, and community clinics.

    This study aimed to investigate the risk factors associated with provoked pulmonary embolism (PE). This retrospective cohort study included 237 patients with PE. Patients that had transient risk factors at diagnosis were classified as having provoked PE, with the remaining patients being classified as having unprovoked PE. The baseline clinical characteristics and factors associated with coagulation were compared. We evaluated the risk factors associated with provoked PE. Of the 237 PE patients, 73 (30.8%) had provoked PE. The rate of respiratory failure and infection, as well as the disseminated intravascular coagulation score and ratio of right ventricular diameter to left ventricular diameter were significantly higher in patients with provoked PE than in those with unprovoked PE. The protein and activity levels associated with coagulation, including protein C antigen, protein S antigen, protein S activity, anti-thrombin III antigen, and factor VIII, were significantly lower in patients with provoked PE than in those with unprovoked PE. Multivariate analysis showed that infection (odds ratio [OR], 3.2; 95% confidence interval [CI], 1.4 to 7.4) and protein S activity (OR, 0.97; 95% CI, 0.95 to 0.99) were significantly associated with provoked PE. Protein S activity and presence of infection were important factors associated with provoked PE. We should pay attention to the presence of infection in patients with provoked PE.

    The study analyzes the existence of naturally biased associations in the general population between a series of musical selections and a series of quatrains. Differently from other studies in the field, the association is tested between complex stimuli involving literary texts, which increases the load of the semantic factors. The stimuli were eight quatrains taken from the same poem and eight musical clips taken from a classical musical version of the poem. The experiment was conducted in two phases. First, the participants were asked to rate 10 couples of opposite adjectives on a continuous bipolar scale when reading a quatrain or when listening to a musical clip; then they were asked to associate a given clip directly with the quatrains in decreasing order. The results showed the existence of significant associations between the semantics of the quatrains and the musical selections. They also confirmed the correspondences experienced by the composer when writing the musical version of the poem. Connotative dimensions such as rough or smooth, distressing or serene, turbid or clear, and gloomy or bright, characterizing both the semantic and the auditory stimuli, may have played a role in the associations. The results also shed light on the accomplishment of the two diverse methodologies adopted in the two different phases of the test. Finally, the role of specific musical components and their combinations is likely to have played an important role in the associations, an aspect that shall be addressed in further studies.

    Copy number variation (CNV) plays a role in pathogenesis of many human diseases, especially cancer. Several whole genome CNV association studies have been performed for the purpose of identifying cancer associated CNVs. Here we undertook a novel approach to whole genome CNV analysis, with the goal being identification of associations between CNV of different genes (CNV-CNV) across 60 human cancer cell lines. We hypothesize that these associations point to the roles of the associated genes in cancer, and can be indicators of their position in gene networks of cancer-driving processes. Recent studies show that gene associations are often non-linear and non-monotone. In order to obtain a more complete picture of all CNV associations, we performed omnibus univariate analysis by utilizing dCov, MIC, and HHG association tests, which are capable of detecting any type of association, including non-monotone relationships. For comparison we used Spearman and Pearson association tests, which detect only linear or monotone relationships. Application of dCov, MIC and HHG tests resulted in identification of twice as many associations compared to those found by Spearman and Pearson alone. Interestingly, most of the new associations were detected by the HHG test. Next, we utilized dCov's and HHG's ability to perform multivariate analysis. We tested for association between genes of unknown function and known cancer-related pathways. Our results indicate that multivariate analysis is much more effective than univariate analysis for the purpose of ascribing biological roles to genes of unknown function. We conclude that a combination of multivariate and univariate omnibus association tests can reveal significant information about gene networks of disease-driving processes. These methods can be applied to any large gene or pathway dataset, allowing more comprehensive analysis of biological processes.

    Full Text Available AbstractBackground: Endometriosis is a common gynecological problem associated with chronic pelvic pain. Objective: To evaluate the effectiveness of current hormonal treatments of endometriosis associated pain.Materials and Methods: Randomized Controlled studies identified from databases of Medline and Cochrane Systemic Review groups were pooled. 7 RCTs were recruited for evaluation in this review. Data from these studies were pooled and meta-analysis was performed in three comparison groups: 1 Progestogen versus GnRHa; 2 Implanon versus Progestogen (injection; 3 Combined oral contraceptive pills versus placebo and progestogen. Response to treatment was measured as a reduction in pain score. Pain improvement was defined as improvement ≥1 at the end of treatment. Results: There was no significant difference between treatment groups of progestogen and GnRHa (RR: 0.036; CI:-0.030-0.102 for relieving endometriosis associated pelvic pain. Long acting progestogen (Implanon and Mirena are not inferior to GnRHa and depot medroxy progesterone acetate (DMPA (RR: 0.006; CI:-0.142-0.162. Combined oral contraceptive pills demonstrated effective treatment of relieving endometriosis associated pelvic pain when compared with placebo groups (RR:0.321CI-0.066-0.707. Progestogen was more effective than combined oral contraceptive pills in controlling dysmenorrhea (RR:-0.160; CI:-0.386-0.066, however, progestogen is associated with more side effects like spotting and bloating than the combined contraceptive pills. Conclusion: Combined oral contraceptive pills (COCP, GnRHa and progestogens are equally effective in relieving endometriosis associated pelvic pain. COCP and progestogens are relatively cheap and more suitable for long-term use as compared to GnRHa. Long-term RCT of medicated contraceptive devices like Mirena and Implanon are required to evaluate their long-term effects on relieving the endometriosis associated pelvic pain

    The objective of this study was to establish the risk factors associated with both lambing difficulty and lamb mortality in the Irish sheep multibreed population. A total of 135 470 lambing events from 42 675 ewes in 839 Irish crossbred and purebred flocks were available. Risk factors associated with producer-scored ewe lambing difficulty score (scale of one (no difficulty) to four (severe difficulty)) were determined using linear mixed models. Risk factors associated with the logit of the probability of lamb mortality at birth (i.e. binary trait) were determined using generalised estimating equations. For each dependent variable, a series of simple regression models were developed as well as a multiple regression model. In the simple regression models, greater lambing difficulty was associated with quadruplet bearing, younger ewes, of terminal breed origin, lambing in February; for example, first parity ewes experienced greater (P7.0 kg) birth weights, quadruplet born lambs and lambs that experienced a more difficult lambing (predicted probability of death for lambs that required severe and veterinary assistance of 0.15 and 0.32, respectively); lambs from dual-purpose breeds and born to younger ewes were also at greater risk of mortality. In the multiple regression model, the association between ewe parity, age at first lambing, year of lambing and lamb mortality no longer persisted. The trend in solutions of the levels of each fixed effect that remained associated with lamb mortality in the multiple regression model, did not differ from the trends observed in the simple regression models although the differential in relative risk between the different lambing difficulty scores was greater in the multiple regression model. Results from this study show that many common flock- and animal-level factors are associated with both lambing difficulty and lamb mortality and management of different risk category groups (e.g. scanned litter sizes, ewe age groups) can be used

    Objectives: Bullying is a serious public health issue. We sought to demonstrate an association between bullying victimization and hospital admissions for acute psychiatric problems. We described the demographics and types of bullying in a sample of hospitalized patients in Staten Island, NY, and compared bullying victimization scores with psychiatric versus medical admissions. Methods: Patients in grades 3–12 were recruited from the Staten Island University Hospital Inpatient Pediatrics unit and emergency department. Patients completed the validated Olweus Bully/Victim Questionnaire (OBQ) was analyzed to formulate a report of bullying in our sample as well as a sub-score measurement of bullying victimization. Pediatric residents simultaneously documented whether the subject was a medical versus an in-patient psychiatry admission. Statistical analysis was performed to look for an association between the victimization sub-score and a psychiatric indication for admission. Results: A total of 185 surveys were analyzed. Peak bullying occurred in 7th and 8th grades. Demographics and types of bullying in our sample were described. A strong association between bullying victimization and hospitalization for in-patient psychiatry was demonstrated. Association between bullying victimization and suicidal ideation, psychiatry, and social work consults was also shown. Concern for an association between hospitalization for psychogenic illness and bullying victimization was also raised. Conclusions: There is a significant association between bullying victimization and psychiatric hospital admissions. This raises the specter of the serious consequences of bullying as it is the first study to prospectively link hospital admissions to bullying. Studies using a valid measure of psychogenic illness to look for an association with bullying victimization are needed. PMID:29326819

    2015-01-01

    The genome association databases provide valuable clues to identify novel targets for cancer diagnosis and therapy. Genes harboring phenotype-associated polymorphisms for neoplasm traits can be identified using diverse bioinformatics tools. The recent availability of various protein expression datasets from normal human tissues, including the body fluids, enables for baseline expression profiling of the cancer secretome. Chemoinformatics approaches can help identify drug-like compounds from the protein 3D structures. The National Center for Biotechnology Information (NCBI) Phenome Genome Integrator (PheGenI) tool was enriched for neoplasm-associated traits. The neoplasm genes were characterized using diverse bioinformatics tools for pathways, gene ontology, genome-wide association, protein expression and functional class. Chemogenomics analysis was performed using the canSAR protein annotation tool. The neoplasm-associated traits segregated into 1,305 genes harboring 2,837 single nucleotide polymorphisms (SNPs). Also identified were 65 open reading frames (ORFs) encompassing 137 SNPs. The neoplasm genes and the associated SNPs were classified into distinct tumor types. Protein expression in the secretome was seen for 913 of the neoplasm-associated genes, including 17 novel uncharacterized ORFs. Druggable proteins, including enzymes, transporters, channel proteins and receptors, were detected. Thirty-four novel druggable lead genes emerged from these studies, including seven cancer lead targets. Chemogenomics analysis using the canSAR protein annotation tool identified 168 active compounds (neoplasm genes in the body fluids. Among these, 7 most active lead compounds with drug-like properties (1-600 nM) were identified for the cancer lead targets, encompassing enzymes and receptors. Over seventy percent of the neoplasm trait-associated genes were detected in the body fluids, such as ascites, blood, tear, milk, semen, urine, etc. Ligand-based druggabililty analysis

    Full Text Available Abstract Background Clinical symptoms of affective disorders, their response to light treatment, and sensitivity to other circadian interventions indicate that the circadian system has a role in mood disorders. Possibly the mechanisms involve circadian seasonal and photoperiodic mechanisms. Since genetic susceptibilities contribute a strong component to affective disorders, we explored whether circadian gene polymorphisms were associated with affective disorders in four complementary studies. Methods Four groups of subjects were recruited from several sources: 1 bipolar proband-parent trios or sib-pair-parent nuclear families, 2 unrelated bipolar participants who had completed the BALM morningness-eveningness questionnaire, 3 sib pairs from the GenRed Project having at least one sib with early-onset recurrent unipolar depression, and 4 a sleep clinic patient group who frequently suffered from depression. Working mainly with the SNPlex assay system, from 2 to 198 polymorphisms in genes related to circadian function were genotyped in the participant groups. Associations with affective disorders were examined with TDT statistics for within-family comparisons. Quantitative trait associations were examined within the unrelated samples. Results In NR1D1, rs2314339 was associated with bipolar disorder (P = 0.0005. Among the unrelated bipolar participants, 3 SNPs in PER3 and CSNK1E were associated with the BALM score. A PPARGC1B coding SNP, rs7732671, was associated with affective disorder with nominal significance in bipolar family groups and independently in unipolar sib pairs. In TEF, rs738499 was associated with unipolar depression; in a replication study, rs738499 was also associated with the QIDS-SR depression scale in the sleep clinic patient sample. Conclusion Along with anti-manic effects of lithium and the antidepressant effects of bright light, these findings suggest that perturbations of the circadian gene network at several levels may

    Full Text Available The literature documents that personality characteristics are associated with healthy lifestyles, including smoking. Among positive traits, Positivity (POS, defined as a general disposition conducive to facing experience under a positive outlook has shown robust associations with psychological health. Thus, the present study investigated the extent to which POS is able to predict (i relapse after quitting smoking and (ii the desire to smoke again. All participants (481 had previously attended a Group Counselling Program (GCP for Smoking Cessation (from 2005 through 2010. They were contacted through telephone interview. Among participants, 244 were ex-smokers (age: years 56.3±10.08, 52% female and 237 were still-smokers (age: years 55.0±9.63; 63.5% female. The association of POS with “craving to smoke” levels was assessed with multivariate linear regression analysis while controlling also for important differences in personality such as conscientiousness and general self-efficacy, as well as for gender and age. Results showed that POS was significantly and negatively associated with smoking status and with craving to smoke. Among covariates (i.e., conscientiousness, generalized self-efficacy, gender was associated with smoking status and with craving to smoke. Altogether these findings corroborate the idea that POS plays a significant role in sustaining individuals' efforts to quit smoking.

    We report on the results of a systematic search for associated asteroid families for all active asteroids known to date. We find that 10 out of 12 main-belt comets (MBCs) and five out of seven disrupted asteroids are linked with known or candidate families, rates that have ∼0.1% and ∼6% probabilities, respectively, of occurring by chance, given the overall family association rate of 37% for asteroids in the main asteroid belt. We find previously unidentified family associations between 238P/Read and the candidate Gorchakov family, 311P/PANSTARRS and the candidate Behrens family, 324P/La Sagra and the Alauda family, 354P/LINEAR and the Baptistina family, P/2013 R3-B (Catalina-PANSTARRS) and the Mandragora family, P/2015 X6 (PANSTARRS) and the Aeolia family, P/2016 G1 (PANSTARRS) and the Adeona family, and P/2016 J1-A/B (PANSTARRS) and the Theobalda family. All MBCs with family associations belong to families that contain asteroids with primitive taxonomic classifications and low average reported albedos (\\overline{{p}V}≲ 0.10), while disrupted asteroids with family associations belong to families that contain asteroids that span wider ranges of taxonomic types and average reported albedos (0.06p}V}young asteroid families could lead to the production of present-day MBCs.

    Migraine is a common and highly disabling condition that is particularly prevalent among women and especially women of reproductive age. The tremendous rise in adiposity in the Western world has led to an epidemic of obesity in women. The particular effects of obesity on women with migraine of various ages are the focus of this review. Conflicting findings from various studies with different approaches and populations have made challenging definitive conclusions about associations between migraine and obesity. While the association between obesity and migraine frequency has been consistently demonstrated and obesity is considered a risk factor for progression from episodic to chronic migraine, the association between obesity and migraine prevalence is still somewhat debated and appears to be dependent on gender and age, with the most consistent effects observed in women younger than 55 years of age. Association between migraine and obesity is most commonly observed in women of reproductive age. The multimodal changes associated with age and hormonal change in women likely play a role in this relationship, as obesity does not appear to be related to migraine in women over 55 years of age. Future studies focusing on the migraine-obesity relationship in women should examine the effects of age, endogenous hormonal state, and exogenous hormones on migraine and obesity.

    Diabetic maculopathy is characterised by increased capillary leakage in the main retinal vessels and by alterations in the microcirculation of the macula. Maculopathy occurs frequently in type 1 and type 2 diabetic patients. Prevalence is higher in type 2 than in type 1 diabetic patients. Factors associated with the development of maculopathy are mostly unknown. As maculopathy is the main cause of vision deprivation in diabetic patients it is essential to know the associations and risk factors of diabetic maculopathy so that appropriate measures can be taken to prevent as well as treat diabetic maculopathy. We started the research work to find out the relation between diabetic maculopathy and various associated factors and risk factors for patients with diabetic retinopathy with maculopathy. This cross-sectional observational study done at the Department of Ophthalmology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka & National Institute of Ophthalmology & Hospital (NIO & H), Sher-e-Bangla Nagar, Dhaka, Bangladesh from January 2006 to June 2006. In this study out of 50 patients, diabetes was controlled in 20(40%) patients and uncontrolled in 30(60%). A significant percentage of patients (40%) had elevated blood pressure. Diabetic autonomic neuropathy was observed in 24% cases and polyneuropathy was observed in 36% cases. It is evident that diabetic maculopathy has association with dyslipidaemia, abnormal renal function due to nephropathy. This study lighted on the association of diabetic maculopathy with diabetic nephropathy, cardiac abnormalities and diabetic neuropathy.

    2017-07-01

    Dapsone is a sulfone drug used to treat infectious conditions and also numerous dermatologic diseases. Fixed drug eruption is a distinctive adverse cutaneous reaction associated with the initial administration and subsequent delivery of a specific agent. Areas covered: The authors preformed a literature search using the following keywords: dapsone, fixed drug eruption, and adverse cutaneous drug reaction. Bibliographies were also reviewed for pertinent articles. The results were combed for relevant papers and reviewed. Articles pertaining to dapsone-associated fixed drug eruption were included. Expert commentary: The majority of cases of dapsone-associated fixed drug eruption in the literature come from Africa or India where there is a high prevalence of patients treated for leprosy. Characteristics of these cases are similar to fixed drug eruption described in the western literature, with differences in frequency of multiple versus solitary lesions. Dapsone-associated fixed drug eruption should be considered when reviewing the drug history of a patient with fixed drug eruption. In the case of darker pigmented individuals, multiple fixed drug eruption lesions may be more common. Multiple lesions may mimic Kaposi's sarcoma in human immunodeficiency virus positive patients. Dapsone-associated fixed drug eruption should be considered in the differential diagnosis of multiple hyperpigmented lesions.

    Colors and odors are associated; for instance, people typically match the smell of strawberries to the color pink or red. These associations are forms of crossmodal correspondences. Recently, there has been discussion about the extent to which these correspondences arise for structural reasons (i.e., an inherent mapping between color and odor), statistical reasons (i.e., covariance in experience), and/or semantically-mediated reasons (i.e., stemming from language). The present study probed this question by testing color-odor correspondences in 6 different cultural groups (Dutch, Netherlands-residing-Chinese, German, Malay, Malaysian-Chinese, and US residents), using the same set of 14 odors and asking participants to make congruent and incongruent color choices for each odor. We found consistent patterns in color choices for each odor within each culture, showing that participants were making non-random color-odor matches. We used representational dissimilarity analysis to probe for variations in the patterns of color-odor associations across cultures; we found that US and German participants had the most similar patterns of associations, followed by German and Malay participants. The largest group differences were between Malay and Netherlands-resident Chinese participants and between Dutch and Malaysian-Chinese participants. We conclude that culture plays a role in color-odor crossmodal associations, which likely arise, at least in part, through experience. PMID:25007343

    2014-01-01

    Recent studies have suggested that incarceration dramatically increases the odds of divorce, but we know little about the mechanisms that explain the association. This study uses prospective longitudinal data from a subset of married young adults in the National Longitudinal Study of Adolescent Health (N = 1,919) to examine whether incarceration is associated with divorce indirectly via low marital love, economic strain, relationship violence, and extramarital sex. The findings confirmed that incarcerations occurring during, but not before, a marriage were associated with an increased hazard of divorce. Incarcerations occurring during marriage also were associated with less marital love, more relationship violence, more economic strain, and greater odds of extramarital sex. Above-average levels of economic strain were visible among respondents observed preincarceration, but only respondents observed postincarceration showed less marital love, more relationship violence, and higher odds of extramarital sex than did respondents who were not incarcerated during marriage. These relationship problems explained approximately 40 percent of the association between incarceration and marital dissolution. These findings are consistent with theoretical predictions that a spouse’s incarceration alters the rewards and costs of the marriage and the relative attractiveness of alternative partners.

    Patients often complain about insufficient sleep or chronic insomnia in the belief that they need 8 hours of sleep. Treatment strategies may be guided by what sleep durations predict optimal survival and whether insomnia might signal mortality risks. In 1982, the Cancer Prevention Study II of the American Cancer Society asked participants about their sleep duration and frequency of insomnia. Cox proportional hazards survival models were computed to determine whether sleep duration or frequency of insomnia was associated with excess mortality up to 1988, controlling simultaneously for demographics, habits, health factors, and use of various medications. Participants were more than 1.1 million men and women from 30 to 102 years of age. The best survival was found among those who slept 7 hours per night. Participants who reported sleeping 8 hours or more experienced significantly increased mortality hazard, as did those who slept 6 hours or less. The increased risk exceeded 15% for those reporting more than 8.5 hours sleep or less than 3.5 or 4.5 hours. In contrast, reports of "insomnia" were not associated with excess mortality hazard. As previously described, prescription sleeping pill use was associated with significantly increased mortality after control for reported sleep durations and insomnia. Patients can be reassured that short sleep and insomnia seem associated with little risk distinct from comorbidities. Slight risks associated with 8 or more hours of sleep and sleeping pill use need further study. Causality is unproven.

  5. Detecting local haplotype sharing and haplotype association.

    A novel haplotype association method is presented, and its power is demonstrated. Relying on a statistical model for linkage disequilibrium (LD), the method first infers ancestral haplotypes and their loadings at each marker for each individual. The loadings are then used to quantify local haplotype sharing between individuals at each marker. A statistical model was developed to link the local haplotype sharing and phenotypes to test for association. We devised a novel method to fit the LD model, reducing the complexity from putatively quadratic to linear (in the number of ancestral haplotypes). Therefore, the LD model can be fitted to all study samples simultaneously, and, consequently, our method is applicable to big data sets. Compared to existing haplotype association methods, our method integrated out phase uncertainty, avoided arbitrariness in specifying haplotypes, and had the same number of tests as the single-SNP analysis. We applied our method to data from the Wellcome Trust Case Control Consortium and discovered eight novel associations between seven gene regions and five disease phenotypes. Among these, GRIK4, which encodes a protein that belongs to the glutamate-gated ionic channel family, is strongly associated with both coronary artery disease and rheumatoid arthritis.

    To examine the association between specific attributes of neighborhood environments and four social environment measures. Data were collected as part of a baseline survey among participants enrolling in a walking intervention. Participants were recruited from a metropolitan area in a Southeastern state. Participants (n = 294) were predominantly African-American (67%) and female (86%), with some college education (79%) and a mean age of 49. The International Physical Activity Questionnaire Environment Module assessed perceptions about neighborhood attributes. The social environment was assessed using three distinct scales: social cohesion, social interactions with neighbors, and social support for physical activity from family and friends. Multiple regression models examined associations between neighborhood attributes and social environment measures, adjusting for demographic variables. Having walkable destinations and having access to amenities and transit stops were associated with increased interactions with neighbors (b = 1.32, 1.04, and 1.68, respectively, p bike lanes, racks) were associated with social support for physical activity from family and friends (b = .43 and .30, respectively, p < .05). The study highlights key attributes of neighborhood environments that may be associated with the social context of such settings. © 2016 by American Journal of Health Promotion, Inc.

    Social media are widely used by the general public and by public health and health care professionals. Emerging evidence suggests engagement with public health information on social media may influence health behavior. However, the volume of data accumulating daily on Twitter and other social media is a challenge for researchers with limited resources to further examine how social media influence health. To address this challenge, we used crowdsourcing to facilitate the examination of topics associated with engagement with diabetes information on Twitter. We took a random sample of 100 tweets that included the hashtag "#diabetes" from each day during a constructed week in May and June 2014. Crowdsourcing through Amazon's Mechanical Turk platform was used to classify tweets into 9 topic categories and their senders into 3 Twitter user categories. Descriptive statistics and Tweedie regression were used to identify tweet and Twitter user characteristics associated with 2 measures of engagement, "favoriting" and "retweeting." Classification was reliable for tweet topics and Twitter user type. The most common tweet topics were medical and nonmedical resources for diabetes. Tweets that included information about diabetes-related health problems were positively and significantly associated with engagement. Tweets about diabetes prevalence, nonmedical resources for diabetes, and jokes or sarcasm about diabetes were significantly negatively associated with engagement. Crowdsourcing is a reliable, quick, and economical option for classifying tweets. Public health practitioners aiming to engage constituents around diabetes may want to focus on topics positively associated with engagement.

    Full Text Available The prevalence and characteristics of small regulatory RNAs (sRNAs have not been well characterized for Bacillus subtilis, an important model system for Gram-positive bacteria. However, B. subtilis was recently found to synthesize many candidate sRNAs during stationary phase. In the current study, we performed deep sequencing on Hfq-associated RNAs and found that a small subset of sRNAs associates with Hfq, an enigmatic RNA-binding protein that stabilizes sRNAs in Gram-negatives, but whose role is largely unknown in Gram-positive bacteria. We also found that Hfq associated with antisense RNAs, antitoxin transcripts, and many mRNA leaders. Several new candidate sRNAs and mRNA leader regions were also discovered by this analysis. Additionally, mRNA fragments overlapping with start or stop codons associated with Hfq, while, in contrast, relatively few full-length mRNAs were recovered. Deletion of hfq reduced the intracellular abundance of several representative sRNAs, suggesting that B. subtilis Hfq-sRNA interactions may be functionally significant in vivo. In general, we anticipate this catalog of Hfq-associated RNAs to serve as a resource in the functional characterization of Hfq in B. subtilis.

    A prospective study was carried out on 48 patients with HTLV I associated myelopathy/tropical spastic paraparesis (HAM/TSP) to assess the association between this entity and Sjögren's syndrome. Fourteen patients (29.1%) had chronic dacryosialadenitis confirmed by a positive Schirmer's test and salivary gland biopsy. None of these patients had evidence of collagen disease and tests for Ro, La, and rheumatoid factor were negative except in one case. Therefore, the dacryosialadenitis could not be classified as either primary or secondary Sjögren's syndrome. Ten of the 14 patients (71.4%) had other systems (haematological, articular, dermatological, or respiratory) involved apart from the neurological and exocrine gland pathology. The findings suggest that the dacryosialadenitis associated with HTLV I is a disease of viral origin distinct from Sjögren's syndrome.

    The principle of information retrieval by association has been suggested as a basis for parallel computing and as the process by which human memory functions.1 Various associative processors have been proposed that use electronic or optical means. Optical schemes,2-7 in particular, those based on holographic principles,8'8' are well suited to associative processing because of their high parallelism and information throughput. Previous workers8 demonstrated that holographically stored images can be recalled by using relatively complicated reference images but did not utilize nonlinear feedback to reduce the large cross talk that results when multiple objects are stored and a partial or distorted input is used for retrieval. These earlier approaches were limited in their ability to reconstruct the output object faithfully from a partial input.

    To review disorders that are associated with renal cystic disease during prenatal life and to highlight the strong association between renal cystic disease and ciliopathies. There are numerous causative genes for ciliopathies that can present with cystic kidney disease. In the group of single gene ciliopathies, autosomal dominant polycystic kidney disease is by far the most prevalent one. Other examples are autosomal recessive polycystic kidney disease, nephronophthisis, Bardet-Biedl syndrome, Meckel-Gruber syndrome, Joubert syndrome and related disorders as well as X-linked orofaciodigital syndrome type 1, respectively. The prevalence of these inherited disorders sums up to about in 1 : 2000 people. These disorders with their hepatorenal fibrocystic character should be classified as multisystem diseases. Understanding of the origin of renal cystic disease and associated disorders is important to make the appropriate prenatal diagnosis and for counseling affected parents. In the future, understanding of the pathophysiology may help to develop new treatment strategies.

    Shannon-Lowe, Claire; Rickinson, Alan B.

    2017-01-01

    Epstein–Barr virus (EBV), originally discovered through its association with Burkitt lymphoma, is now aetiologically linked to a remarkably wide range of lymphoproliferative lesions and malignant lymphomas of B-, T- and NK-cell origin. Some occur as rare accidents of virus persistence in the B lymphoid system, while others arise as a result of viral entry into unnatural target cells. The early finding that EBV is a potent B-cell growth transforming agent hinted at a simple oncogenic mechanism by which this virus could promote lymphomagenesis. In reality, the pathogenesis of EBV-associated lymphomas involves a complex interplay between different patterns of viral gene expression and cellular genetic changes. Here we review recent developments in our understanding of EBV-associated lymphomagenesis in both the immunocompetent and immunocompromised host. This article is part of the themed issue ‘Human oncogenic viruses’. PMID:28893938

Genetic risk for psychiatric conditions encompass rare variants, identified due to major effect, as well as common variants, the latter analyzed by association analyses. We review guidelines for common variant association analyses, undertaking after assessing evidence of heritability. We highlight the importance of: suitably large sample sizes; an experimental design that controls for ancestry; careful data cleaning; correction for multiple testing; small P values for positive findings; assessment of effect size for positive findings; and, inclusion of an independent replication sample. We also note the importance of a critical discussion of any prior findings, biological follow-up where possible, and a means of accessing the raw data.

    Full Text Available Enlargement of the gingiva can be due to various causes. Most prevalent are the inflammatory type and drug-induced type of gingival hyperplasia. However, sever enlargement associated with an aggressive type of periodontitis is an infrequent finding. Reported here is a case of a female patient aged 18 years who presented with severe enlargement of the maxillary and mandibular gingiva. Examination revealed enlargement extending up to the incisal edge of all the teeth and also an associated generalized loss of attachment with radiographic evidence of reduced bone height resembling an aggressive type of periodontitis. There were no associated systemic signs and symptoms or any family history except that there was generalized vitiligo of the skin and oral mucous membrane. The case was treated by gross electrosection of the gingiva.

    Dentigerous cysts are defined as a cyst originated by separation of the follicle of dental crown of a tooth unerupted. Although most dentigerous cysts are considered developmental cysts, some cases seem to have an inflammatory origin. The aim of this study was to show a case of an 8-year-old patient, male, presenting a lesion in maxilla with large proportions. Computed tomography scans showed a hypodense image, well-defined, associated to unerupted teeth. The case was treated by enucleation of the lesion under local anesthesia. Histopathological examination confirmed the diagnostic suspicious of dentigerous cyst. Currently, 3-year follow-up period showed no signs of recurrence, and it was observed eruption of the teeth associated to the lesion. This case highlights the importance of the association between clinical and radiographic analysis together to the surgical findings, aiming the best treatment for the patient.

    Properties of optical and molecular outflows associated with young stellar objects are discussed with emphasis placed on new results concerning outflow energetics, collimating structures, and the relationship between the outflow properties and the magnetic field geometry characterizing the host molecular clouds. Particular consideration is given to the IRAS observations of YSO mass outflows, which reveal extended far-IR emission associated with high-velocity molecular gas and in which a number of disk-like structures associated with YSO outflow sources were resolved. The disk axes appeared to lie along the direction of molecular outflows or stellar jets. The mass outflows showed a remarkable tendency to align along the direction of the magnetic fields which thread their host molecular clouds, suggesting that the cloud magnetic field must play an important role in determining the flattening (and perhaps the rotation) of protostellar structures.

  4. The association between obesity and gynecological cancer

    2015-11-01

    Full Text Available Obesity is a growing problem and has significant implications for a variety of diseases, including human cancers. A positive association between obesity and incidence of many gynecological cancers, including endometrial cancer, ovarian cancer, and breast cancer has been observed. The mechanism proposed to connect obesity and these cancers was sex hormone, insulin resistance, and certain adipokines. Obesity adversely affects survival in most studies. For endometrial cancer, the obesity was associated with increased risk and unfavorable outcome. With regard to ovarian cancer and cervical cancer, the evidence was inconsistent. The positive association between obesity and the risk of postmenopausal breast cancer has been consistently observed but it is not the same story in premenopausal breast cancer. But the prognosis for both pre- and postmenopausal breast cancer was substantially worse among obese than normal-weight individuals. In this article, we review the current evidence linking obesity with risk and outcome of gynecological cancers.

    2010-01-01

    To inform development of tuberculosis (TB) control strategies, we characterized a total of 2,261 Mycobacterium tuberculosis complex isolates by using multiple phenotypic and molecular markers, including polymorphisms in repetitive sequences (spoligotyping and variable-number tandem repeats [VNTRs]) and large sequence and single-nucleotide polymorphisms. The Beijing family was strongly associated with multidrug resistance (p = 0.0001), and VNTR allelic variants showed strong associations with spoligotyping families: >5 copies at exact tandem repeat (ETR) A, >2 at mycobacterial interspersed repetitive unit 24, and >3 at ETR-B associated with the East African–Indian and M. bovis strains. All M. tuberculosis isolates were differentiated into 4 major lineages, and a maximum parsimony tree was constructed suggesting a more complex phylogeny for M. africanum. These findings can be used as a model of pathogen global diversity. PMID:20113558

    2007-02-01

    The aim of the study described here was to determine those variables associated with employment in patients followed at a level 4 epilepsy center. A survey was sent to patients seen at the University of Florida Health Science Center/Jacksonville Comprehensive Epilepsy Program. Two hundred sixty-two eligible subjects constituted the study population. By univariate analysis, variables that distinguished employed patients included: younger age, Caucasian race, higher education and household income, not receiving disability benefits, currently studying, fewer seizure medications, having no other medical conditions that interfere with work, previous work experience, perceived importance of work for personal and financial reasons, and decreased fears of workplace discrimination. By logistic regression, higher annual family income, perceived importance of work for personal reasons, and decreased fears of workplace discrimination were the only variables independently associated with employment. Psychosocial factors such as a high self-perceived importance of work and decreased fears of workplace discrimination are significantly associated with employment in epilepsy patients.

  8. Neurobiology of inflammation-associated anorexia

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Compelling data demonstrate that inflammation-associated anorexia directly results from the action of pro-inflammatory factors, primarily cytokines and prostaglandins E2, on the nervous system. For instance, the aforementioned pro-inflammatory factors can stimulate the activity of peripheral sensory neurons, and induce their own de novo synthesis and release into the brain parenchyma and cerebrospinal fluid. Ultimately, it results in the mobilization of a specific neural circuit that shuts down appetite. The present article describes the different cell groups and neurotransmitters involved in inflammation-associated anorexia and examines how they interact with neural systems regulating feeding such as the melanocortin system. A better understanding of the neurobiological mechanisms underlying inflammation-associated anorexia will help to develop appetite stimulants for cancer and AIDS patients.

    Goldenhar syndrome is well known for its classical triad of epibulbar dermoids or lipodermoids, auricular appendages and pretragal fistulas. Here we report a case of Goldenhar syndrome with an unusual association of a fibroepithelial polyp attached to a limbal dermoid. A case of Goldenhar syndrome in a 5-month-old male infant presented with the features of a fibroepithelial polyp attached to a limbal dermoid, right-sided polydactylia with hypoplastic thumb, and accessory preauricular appendages on the left side. The association of a fibroepithelial polyp attached to a limbal dermoid with Goldenhar syndrome is a rare report in the literature. In these cases, regular follow-up with an ophthalmologist is important to monitor the visual development of the patient. Ideally, a multidisciplinary approach is required to manage the other associated anomalies.

    Unlicensed and off label drug use in children is common and leads to well-recognised problems. This study aimed to determine whether a relationship exists between medication errors and licence status. Reports of errors in a UK children's hospital from 2004 to 2006 were analysed in terms of licence status and degree of harm and compared to the incidence of unlicensed and off label drug use in the hospital. 20 of 158 (13%) errors were considered to have caused moderate harm and 12 of these involved unlicensed/off label drugs. 138 (87%) caused no or low harm. None caused severe harm. Unlicensed drug usage was significantly more likely to be associated with errors than licensed use in both children and neonates. Unlicensed drug use appears to be associated with medication errors in neonates and children. Medication errors causing moderate harm were significantly more likely to be associated with both unlicensed and off label than licensed drugs.

    Arnaoutakis, Konstantinos; Oo, Thein H

    2009-12-01

    : Bronchus-associated Lymphoid Tissue (BALT) lymphomas are a rare type of extranodal marginal zone lymphomas. They comprise 1% of lymphomas and more than two-thirds of all primary non-Hodgkin lymphoma (NHL) of the lung. BALT lymphomas arise from the bronchus-associated lymphoid tissue. This report describes five cases of BALT lymphoma and discusses the pathogenesis, diagnosis, prognosis and treatment of BALT lymphomas. In our cohort of patients, patients were managed with surgery, watchful waiting, chemotherapy, immunotherapy, and chemoimmunotherapy. The outcomes are excellent and projected 5-year survival is 100%. BALT lymphomas are associated with chronic inflammation, and they are often asymptomatic. They have an indolent course and the survival outcome is excellent with different treatment modalities such as surgery, watchful waiting, radiotherapy, chemotherapy, immunotherapy or chemoimmunotherapy.

  12. Associations between Gun Violence Exposure, Gang Associations, and Youth Aggression: Implications for Prevention and Intervention Programs

    2015-01-01

    Full Text Available Using cross-sectional data collected from three middle schools in Southeast Los Angeles, we assessed the association of neighborhood violence exposure, gang associations, and social self-control with past week aggression in a sample of minority youth (n=164. Results from Poisson and logistic regression models showed that direct exposure to gun violence, having friends in gangs, and low social self control were all positively associated with past week aggression. Among girls, having gang affiliated family members was positively associated with aggression, whereas among boys having friends in gangs was associated with past week aggression. Subjective expectations of engagement in future interpersonal violence were associated with being male, having friends in gangs, and fear of neighborhood gun violence. We recommend that youth violence prevention and intervention programs address the impact of family, peers, and gun violence on student coping and identify students with low social self-control who could benefit from social and emotional skills training.

    Factors associated with students' orientations to nursing This paper presents the results of a study focusing on the factors associated with orientations to nursing. Students' orientations to nursing have not as yet been a focus of nursing research. In some other professions, however, professional orientation has been associated with learning motivation and study performance, and has been seen as a predictor of work satisfaction. In this study, students' orientations to nursing were defined in terms of caring, nursing expertise and life orientation. The hypothesis of whether students' pre-educational experiences of nursing, gender, choice of nursing specialty, problems with nursing studies and intention to stay in nursing were associated with different orientations was tested. The extent to which students were orientated to caring, nursing expertise and their own life was also examined. The orientation to nursing measurement tool, which has been developed on the basis of a qualitative study, was used to collect the data. Nurse teachers collected the data from nursing students (n=184) who were studying in three different nursing programmes in Finland. Non-parametric assessments (Mann-Whitney U-test and Kruskal-Wallis test) of the differences between the students' orientations were carried out. A majority of the students were highly life-orientated, and two-thirds had average nursing expertise or caring orientation scores. The results supported the study hypothesis of an association between students' orientations and their gender, choice of nursing speciality, problems with nursing studies and intention to stay in nursing. However, the hypothesis of an association between students' pre-educational nursing experiences and orientation to nursing was not supported. The contradictions between students' orientation to nursing and the philosophy of nursing underlying the study programme may be a source of motivational problems and dissatisfaction with nursing education

    The temporary network, established through the European 5. Framework Programme project ENEN, was given a more permanent character by the foundation of the European Nuclear Education Network Association, a non-profit-making association according to the French law of 1901, pursuing a pedagogic and scientific aim. Its main objective is the preservation and the further development of higher nuclear education and expertise. This objective is realized through the co-operation between the European universities, involved in education and research in the nuclear engineering field, the nuclear research centres and the nuclear industry. The membership of the ENEN Association now consists of 35 universities members and 6 research centres. The paper briefly describes the history and structure of the ENEN Association and elaborates on the objectives and activities of its five committees during its first two years of operation. Supported by the 5. and 6. Framework Programme of the European Community, the ENEN Association established the delivery of the European Master of Science in Nuclear Engineering certificate. In particular, education and training courses have been developed and offered to materialize the core curricula and optional fields of study in a European exchange structure. Pilot editions of those courses and try-outs of training programmes have been successfully organised with a satisfying interest, attendance and performance by the students and the support of nuclear industries and international organisations. The involvement of ENEN in the 6. EC Framework project EUROTRANS will further enlarge its field of activities into a realm of nuclear disciplines. The ENEN Association further contributes to the management of nuclear knowledge within the European Union as well as on a world-wide level, through contacts with its sister Network ANENT in Asia, and by its participation to activities of the World Nuclear University.

  15. Automated detection and association of surface waves

    C. R. D. Woodgold

    1994-06-01

    Full Text Available An algorithm for the automatic detection and association of surface waves has been developed and tested over an 18 month interval on broad band data from the Yellowknife array (YKA. The detection algorithm uses a conventional STA/LTA scheme on data that have been narrow band filtered at 20 s periods and a test is then applied to identify dispersion. An average of 9 surface waves are detected daily using this technique. Beamforming is applied to determine the arrival azimuth; at a nonarray station this could be provided by poIarization analysis. The detected surface waves are associated daily with the events located by the short period array at Yellowknife, and later with the events listed in the USGS NEIC Monthly Summaries. Association requires matching both arrival time and azimuth of the Rayleigh waves. Regional calibration of group velocity and azimuth is required. . Large variations in both group velocity and azimuth corrections were found, as an example, signals from events in Fiji Tonga arrive with apparent group velocities of 2.9 3.5 krn/s and azimuths from 5 to + 40 degrees clockwise from true (great circle azimuth, whereas signals from Kuriles Kamchatka have velocities of 2.4 2.9 km/s and azimuths off by 35 to 0 degrees. After applying the regional corrections, surface waves are considered associated if the arrival time matches to within 0.25 km/s in apparent group velocity and the azimuth is within 30 degrees of the median expected. Over the 18 month period studied, 32% of the automatically detected surface waves were associated with events located by the Yellowknife short period array, and 34% (1591 with NEIC events; there is about 70% overlap between the two sets of events. Had the automatic detections been reported to the USGS, YKA would have ranked second (after LZH in terms of numbers of associated surface waves for the study period of April 1991 to September 1992.

  16. Sequence robust association test for familial data.

    2017-09-01

    Genome-wide association studies (GWAS) and next generation sequencing studies (NGSS) are often performed in family studies to improve power in identifying genetic variants that are associated with clinical phenotypes. Efficient analysis of genome-wide studies with familial data is challenging due to the difficulty in modeling shared but unmeasured genetic and/or environmental factors that cause dependencies among family members. Existing genetic association testing procedures for family studies largely rely on generalized estimating equations (GEE) or linear mixed-effects (LME) models. These procedures may fail to properly control for type I errors when the imposed model assumptions fail. In this article, we propose the Sequence Robust Association Test (SRAT), a fully rank-based, flexible approach that tests for association between a set of genetic variants and an outcome, while accounting for within-family correlation and adjusting for covariates. Comparing to existing methods, SRAT has the advantages of allowing for unknown correlation structures and weaker assumptions about the outcome distribution. We provide theoretical justifications for SRAT and show that SRAT includes the well-known Wilcoxon rank sum test as a special case. Extensive simulation studies suggest that SRAT provides better protection against type I error rate inflation, and could be much more powerful for settings with skewed outcome distribution than existing methods. For illustration, we also apply SRAT to the familial data from the Framingham Heart Study and Offspring Study to examine the association between an inflammatory marker and a few sets of genetic variants. © 2017, The International Biometric Society.

  17. POSITIVE ASSOCIATION BETWEEN TINNITUS AND ARTERIAL HYPERTENSION

    2016-10-01

    Full Text Available Introduction: Tinnitus is the perception of noise in the absence of an external source and is considered by most authors as a multifactorial symptom. A systematic review concerning the association of tinnitus and systemic arterial hypertension retrieved suggestions of a positive association, but the articles included failed to perform a detailed analysis on the theme. Purpose: To analyze the presence of arterial hypertension in tinnitus and non-tinnitus patients. To analyze differences between tinnitus impact and psychoacoustic measurements in hypertensive and normotensive patients and to evaluate the association between the presence of tinnitus and the diverse antihypertensive drugs employed. Material and method: Cross-sectional transversal study, comparing two groups of subjects ( 144 in the study group with tinnitus and 140 in the control group, without tinnitus. Clinical, demographical, audiometrical and psychoacoustics characteristics of the subjects were compared. Results: Hypertension prevalence in tinnitus subjects was 44.4% against 31.4% in subjects without tinnitus (p=0.024. Positive associations with tinnitus were found with hypertension treatment with angiotensin-converting enzyme inhibitors ( p=0.006, tiazidic diuretics (p<0,0001, potassium-sparing diuretics ( p=0.016 and calcium channels blockers (p=0.004. Conclusions: There is an association between tinnitus and arterial hypertension. This association is particularly strong in older patients. Hypertension treatment with diuretics, angiotensin-converting enzyme inhibitors and calcium channels blockers was more prevalent in tinnitus patients, suggesting that an eventual ototoxicity of these drugs may be involved in tinnitus pathophysiology, a hypothesis that should be evaluated in further studies.

    Relapsing polychondritis (RP) is a rare inflammatory disorder of the cartilagenous structures, and it sometimes involves the central nervous system. Encephalitis associated with RP causes a wide variety of symptoms according to the affected sites. We herein report the first case of 72-year-old right-handed man who developed acute meningoencephalitis associated with RP involving the corpus callous. After immunosuppressive therapy, his symptoms dramatically improved, but difficulty in performing bimanual movements with occasional diagonistic dyspraxia in his right hand remained. Because callosal signs are easily missed, especially in acute settings, it would be useful to know that RP can sometimes cause callosal disconnection syndrome.

    BACKGROUND: Saffold virus was described in 2007 as one of the first human viruses within the genus cardioviruses. Cardioviruses may cause severe infections of the myocardium in animals, and several studies have associated saffold virus with human disease. As a result, saffold virus has been...... in the myocardium, lung tissue and blood of one child and was accompanied by histopathological inflammation in the heart and lungs, which was supportive of a viral infection. These findings suggest that cardioviruses may be associated with myocarditis in humans....

    This paper is devoted to the study of approximate algorithms for minimization of partial association rule length. It is shown that under some natural assumptions on the class NP, a greedy algorithm is close to the best polynomial approximate algorithms for solving of this NP-hard problem. The paper contains various bounds on precision of the greedy algorithm, bounds on minimal length of rules based on an information obtained during greedy algorithm work, and results of the study of association rules for the most part of binary information systems. © 2009 Springer Berlin Heidelberg.

    Rubinstein-Taybi syndrome is a constellation of clinical findings characterized by mental and motor retardation, broad thumbs and broad first toes, typical facies. Ocular and adnexal abnormalities are quite common and include antimongoloid slant of the palpebral fissures, epicanthal folds, congenital obstruction of the lacrimal excretory system, ptosis, strabismus, congenital cataract and congenital glaucoma. The authors describe the case of a 1-year-old male with the Rubinstein-Taybi syndrome associated with unilateral congenital glaucoma. The case emphasizes the importance of detailed complete ocular examinations in patients with Rubinstein-Taybi syndrome, and also highlights the occurrence of ocular abnormalities rarely associated with this disease.

    Tracheal anomalies are known in association with congenital cardiac defects. Some of the well-described anomalies include accessory (displaced) tracheal bronchus with variants, tracheal trifurcation and accessory cardiac bronchus. Here we describe a case of tracheal quadrifurcation associated with complex congenital heart disease. Illustration of complex airway anatomy was simplified by the use of multidetector CT using a variety of image display options. Awareness of this complex anomaly will expand our knowledge of tracheal anomalies and equip the anesthesia and surgical team for better airway management. (orig.)

    Marked hyperamylasaemia associated with an amylase-producing multiple myeloma appears to be a fairly unusual phenomenon. The present report describes a fatal case of multiple myeloma associated with paraneoplastic hyperamylasaemia without evidence of pancreatic or salivary gland involvement. Serum and urine amylase levels paralleled the myeloma response to chemotherapy and disease progression. The importance of paraneoplastic hyperamylasaemia as a useful myeloma marker to monitor disease progression and treatment response is emphasized. Conventional chemotherapy at diagnosis and salvage treatment with bortezomib at relapse failed to achieve a long-term response and to decrease the serum amylase to a normal level. 2007 S.

    A 23-year-old man presented with a 2-week history of intracranial hypertension. CT showed a large, nonenhancing cerebellar mass with surrounding calcification and displacement of the fourth ventricle. MRI revealed a septate lesion, with low signal on T1-weighted and high signal on T2-weighted images. The cerebellar tonsils were displaced below the foramen magnum and there was associated syringomyelia. The MRI features were characteristic of Lhermitte-Duclos (LD) disease (dysplastic gangliocytoma) and the diagnosis was confirmed following surgery. In this case, we emphasise the usefulness of MRI in the diagnosis of LD disease and consider the possible pathogenesis of the associated syringomyelia. (orig.)

    Pancreatic heterotopias (HP) are rare. They can occur at any age with a slight male predominance. These lesions are usually asymptomatic and they are often found incidentally during upper or lower GI endoscopy or during the anatomo-pathological examination of an organ which was resected for other reasons; they can be isolated or associated with a digestive pathology. We report, through observation, the association of HP with serous cystadenoma of the pancreas discovered during examinations to identify the etiology of isolated abdominal pain. The aim of this study is to analyse clinical and histological features of this rare pathology.

    2009-04-01

    The European Concerted Action Project \\'Homocysteine and Vascular Disease\\' showed that an elevated homocysteine is associated with a substantially increased risk of cardiovascular disease, and particularly when combined with other factors such as smoking, hypertension and hypercholesterolaemia. The purpose of this study was to examine the potential interactions between homocysteine and individual lipid subfractions. In addition, it was hypothesized that HDL cholesterol may protect against hyperhomocysteinaemia because HDL cholesterol is associated with the enzyme paroxonase, which reduces oxidization of homocysteine to the harmful metabolite, homocysteine thiolactonase.

    2015-01-01

    Placement of percutaneous endoscopic gastrostomy or jejunostomy is a safe procedure with low periprocedural mortality, but overall mortality rates are high because of underlying disease conditions. These procedures are also associated with postprocedure complications. The clinically significant adverse events related to the procedures include infection (at tube site and peritonitis), bleeding, and aspiration. More rare associated events include buried bumpers, injury to adjacent viscera with subsequent fistula formation, and tumor seeding. There is a lack of guidelines about these procedures other than those concerning the use of antibiotics and the management of antithrombotics and anticoagulation before the procedure.

For pure water a four-site scheme is shown to be the most appropriate scheme. In the case of pure alcohols, a three-site scheme is best for methanol; two- or three......-site schemes perform about equally for ethanol; for higher alcohols a two-site scheme is preferred. This is in accordance with steric arguments. Some difficulties in the interpretation of spectroscopic data and their comparison with the predictions of association models are illustrated.

    Full Text Available Robert C Bransfield Department of Psychiatry, Rutgers-RWJ Medical School, Piscataway, NJ, USA Purpose: The aim of this paper is to investigate the association between suicide and Lyme and associated diseases (LAD. No journal article has previously performed a comprehensive assessment of this subject.Introduction: Multiple case reports and other references demonstrate a causal association between suicidal risk and LAD. Suicide risk is greater in outdoor workers and veterans, both with greater LAD exposure. Multiple studies demonstrate many infections and the associated proinflammatory cytokines, inflammatory-mediated metabolic changes, and quinolinic acid and glutamate changes alter neural circuits which increase suicidality. A similar pathophysiology occurs in LAD.Method: A retrospective chart review and epidemiological calculations were performed.Results: LAD contributed to suicidality, and sometimes homicidality, in individuals who were not suicidal before infection. A higher level of risk to self and others is associated with multiple symptoms developing after acquiring LAD, in particular, explosive anger, intrusive images, sudden mood swings, paranoia, dissociative episodes, hallucinations, disinhibition, panic disorder, rapid cycling bipolar, depersonalization, social anxiety disorder, substance abuse, hypervigilance, generalized anxiety disorder, genital–urinary symptoms, chronic pain, anhedonia, depression, low frustration tolerance, and posttraumatic stress disorder. Negative attitudes about LAD from family, friends, doctors, and the health care system may also contribute to suicide risk. By indirect calculations, it is estimated there are possibly over 1,200 LAD suicides in the US per year.Conclusion: Suicidality seen in LAD contributes to causing a significant number of previously unexplained suicides and is associated with immune-mediated and metabolic changes resulting in psychiatric and other symptoms which are possibly

    Envenomation by the brown recluse spider (Loxosceles reclusa) is associated with shock, significant hemolysis, renal insufficiency, and disseminated intravascular coagulation (DIC). Shock has never been associated with envenomation by L arizonica, a related species indigenous to Arizona, southern California, and northwestern Mexico. We report the case of a 13-year-old girl, bitten by a specimen of L arizonica (the spider was identified by an entomologist), in whom shock and a typical cutaneous lesion developed. She did not experience renal insufficiency or disseminated intravascular coagulation. Infectious causes of shock were excluded. She recovered completely with supportive care.

    The Deutsche Gesellschaft für Urologie (German Urological Association), established in 1907, was a German-Austrian medical society in which Jewish physicians held important positions. When the Nazis seized power in 1933, the Austrian Hans Rubritius was president of the society. The non-German presidency and the exclusion of Jewish colleagues from the professional society and medical practice led to a halt of the society's activities. At the same time in the mid 1930s, German urologists founded the Gesellschaft Reichsdeutscher Urologen (Association of Reichs-German Urologists) whose members aligned themselves with Nazi health policies and in turn received professional and personal benefits.

    Full Text Available Pulmonary hypertension (PH is an important cause of morbidity and mortality in connective tissue diseases (CTDs. CTDs may cause PH due to several mechanisms; pulmonary arterial hypertension, associated interstitial lung disease, neuromuscular disease, and/or sleep disordered breathing leading to hypoxia, associated thromboembolic PH, and pulmonary venous hypertension due to left ventricular dysfunction. PH can be measured on echocardiography, but the gold standard for diagnosis is right heart catheterization. PH-specific therapy in addition to immunosuppression is the most common treatment used though data are scant. In this narrative review, we discuss the epidemiologic burden, clinical presentation, evaluation, and management of PH in CTDs.

    Full Text Available Intracranial lipomas represent less than 0.1% of all intracranial tumors. They are usually located in the callus area and often asymptomatic. This paper presents a sudden death case after an episode of convulsions on a 39 years old woman with a history of migraines and seizures since adolescence. The autopsy revealed the presence of an undiagnosed massive brain lipoma (60 × 35 mm associated with atrophy of the corpus callosum. Although very rare and seldom malignant these may be associated with seizures and sudden death.

    Usual sleep duration is a heritable trait correlated with psychiatric morbidity, cardiometabolic disease and mortality, although little is known about the genetic variants influencing this trait. A genome-wide association study of usual sleep duration was conducted using 18 population-based cohorts totaling 47,180 individuals of European ancestry. Genome-wide significant association was identified at two loci. The strongest is located on chromosome 2, in an intergenic region 35–80 kb upstream from the thyroid-specific transcription factor PAX8 (lowest p=1.1 ×10−9). This finding was replicated in an African-American sample of 4771 individuals (lowest p=9.3 × 10−4). The strongest combined association was at rs1823125 (p=1.5 × 10−10, minor allele frequency 0.26 in the discovery sample, 0.12 in the replication sample), with each copy of the minor allele associated with a sleep duration 3.1 minutes longer per night. The alleles associated with longer sleep duration were associated in previous genome-wide association studies with a more favorable metabolic profile and a lower risk of attention deficit hyperactivity disorder. Understanding the mechanisms underlying these associations may help elucidate biological mechanisms influencing sleep duration and its association with psychiatric, metabolic and cardiovascular disease.

    Background and Purpose Ischemic stroke (IS) shares many common risk factors with coronary artery disease (CAD). We hypothesized that genetic variants associated with myocardial infarction (MI) or CAD may be similarly involved in the etiology of IS. To test this hypothesis, we evaluated whether single-nucleotide polymorphisms (SNPs) at 11 different loci recently associated with MI or CAD through genome-wide association studies were associated with IS. Methods Meta-analyses of the associations between the 11 MI-associated SNPs and IS were performed using 6865 cases and 11 395 control subjects recruited from 9 studies. SNPs were either genotyped directly or imputed; in a few cases a surrogate SNP in high linkage disequilibrium was chosen. Logistic regression was performed within each study to obtain study-specific βs and standard errors. Meta-analysis was conducted using an inverse variance weighted approach assuming a random effect model. Results Despite having power to detect odds ratio of 1.09–1.14 for overall IS and 1.20–1.32 for major stroke subtypes, none of the SNPs were significantly associated with overall IS and/or stroke subtypes after adjusting for multiple comparisons. Conclusions Our results suggest that the major common loci associated with MI risk do not have effects of similar magnitude on overall IS but do not preclude moderate associations restricted to specific IS subtypes. Disparate mechanisms may be critical in the development of acute ischemic coronary and cerebrovascular events. PMID:22363065

    Full Text Available Family, friends and acquaintances of people with disabilities may be viewed or treated differently by the public due to their association with a stigmatized person. Previous research finds that the public are more willing to engage in relationships with people with physical disability than with mental illness. In addition, attitudes towards associating with people with disabilities has been found to vary by depth of the chosen relationship. The current study sought to examine the connections between relationship depth (friend/romantic partner/acquaintance, disability type (physical/psychiatric and associative stigma. Adult participants (N=345 were randomly presented with vignettes varying in relationship depth and disability type via an online survey platform. Analyses found no differences in associative stigma between physical and psychiatric disabilities. Participants viewed the vignette actor Rachel as socially warmer when she was a friend or romantic partner of a person with a disability than when she was an acquaintance. Participants rated Rachel as different from themselves when she was romantically involved with the person with disability and were more willing to engage socially with Rachel when she befriended the person with disability rather than when she was a mere acquaintance.

    Growing data show the association of metabolic syndrome (MetS) or its components with cancer development and cancer-related mortality. It is suggested that in MetS and cancer association, insulin resistance and insulin-like growth factor 1 system play a key role, especially adipokines secreted from visceral adipocytes, free fatty acids and aromatase activity contribute to this process. It is also reported that MetS has a link with colorectal, breast, endometrial, pancreas, primary liver and, although controversial, prostate cancer. Although every component of MetS is known to have an association with cancer development, it is still debated whether the effects of these components are additive or synergistic. On the other hand, in the association between MetS and cancer, the role of antidiabetic and antihypertensive treatments including thiazolidinedione, insulin, angiotensin receptor blockers is also suggested. The primary approach in MetS-cancer relation is to prevent risk factors. Life style changes including weight loss and a healthy diet are known to decrease cancer risk in normal population. It is postulated that an insulin-sensitizing agent, metformin, has cancer-preventing effects on diabetic patients. This review discusses the relationship between MetS and cancer from different aspects and examines this relationship in some of the cancers suggested to be linked with MetS. © 2016 S.
