    Traditional Chinese medicine (TCM) syndrome, also known as TCM ZHENG or TCM pattern, is an integral and essential part of TCM theory that helps to guide the design of individualized treatments. A TCM syndrome, in essence, is a characteristic profile of all clinical manifestations in one patient that can be readily identified by a TCM practitioner. In this article, the authors reviewed the presentations of TCM syndromes in seven common malignancies (liver, lung, gastric, breast, colorectal, pancreatic and esophageal cancers), the objectivity and the standardization of TCM syndrome differentiation, the evaluation of TCM syndrome modeling in cancer research, and syndrome differentiation-guided TCM treatment of cancers. A better understanding of TCM syndrome theory, as well as its potential biological basis, may contribute greatly to the clinical TCM diagnosis and the treatment of cancer.

    Refractory nephrotic syndrome (RNS) is an immune-related kidney disease with poor clinical outcomes. Standard treatments include corticosteroids as the initial therapy and other immunosuppressants as second-line options. A substantial proportion of patients with RNS are resistant to or dependent on immunosuppressive drugs and often experience unremitting edema and proteinuria, cycles of remission and relapse, and/or serious adverse events due to long-term immunosuppression. Traditional Chinese medicine has a long history of treating complicated kidney diseases and holds great potential for providing effective treatments for RNS. This review describes the Chinese medical theories relating to the pathogenesis of RNS and discusses the strategies and treatment options using Chinese herbal medicine. Available preclinical and clinical evidence strongly supports the integration of traditional Chinese medicine and Western medicine for improving the outcome of RNS. Herbal medicine such as Astragalus membranaceus, Stephania tetrandra S. Moore, and Tripterygium wilfordii Hook F can serve as the alternative therapy when patients fail to respond to immunosuppression or as the complementary therapy to improve therapeutic efficacy and reduce side effects of immunosuppressive agents. Wuzhi capsules (Schisandra sphenanthera extract) with tacrolimus and tetrandrine with corticosteroids are two herb-drug combinations that have shown great promise and warrant further studies.

    Full Text Available Extravasation of contrast agents is a possible complication of imaging studies. Although extravasations typically cause minimal swelling or erythema, they can lead to compartment syndrome when the volume of extravasation is high. In this article, we will present an exceptional case where an insignificant amount of contrast agent extravasation led to a forearm compartment syndrome in a newborn, who was treated with an extended fasciotomy. We would like to emphasize the preventive techniques and treatment options of this iatrogenic complication in newborns. Close followup of the patient by the nurses, awareness of the parents and the personnel in the radiology department are the most important preventive measures in this extremity-threatening complication. Forearm compartment syndrome due to contrast agent extravasation may progress more rapidly in newborns even with smaller amounts of extravasation and prompt recognition of the pathology and immediate intervention are unevitable.

    Researches on the mechanisms underlying the therapeutic effects of the disease-syndrome combination approach in integrated traditional Chinese and Western medicine are becoming a hot spot in andrology, but many recent studies of this kind have failed to explain the connotation of integrated traditional Chinese and Western medicine in andrology. Related existing problems include repeated researches into the same indexes of action mechanisms of different therapeutic principles of traditional Chinese medicine (TCM), Chinese herbal compound and special prescriptions, studies focusing on individual diseases but ignoring symptoms, immature syndrome models for studies of mechanisms, and too much attention to uncertain or immature target mechanisms. The stress should be placed on the action mechanisms of Chinese herbal compound and special prescriptions on male diseases and, what is more important, on the clarification of the essential principles of differentiation and treatment of TCM syndromes. In the recent years, proteomics, genomics, transcriptomics and metabolomics have shed some light upon researches into the mechanisms underlying the therapeutic effects of the disease-syndrome combination approach in integrated traditional Chinese and Western medicine in andrology. An insight into the TCM syndrome, a macroscopic inductive analysis, and a comprehension of such microcosmic aspects as the gene, protein, metabolism and metagenome may contribute to some breakthroughs and new ideas in the studies of disease-syndrome combination in integrated traditional Chinese and Western medicine in andrology.

    Full Text Available Traditional Chinese medicine (TCM; 中醫 zhōng yī syndrome groups are based on the symptoms of human diseases and guide the use of Chinese herbs. The aim of this study was to examine the effects of TCM syndrome groups on biochemical characteristics and quality of life (QOL in women with metabolic syndrome (MS. Among the 1080 registered female patients screened at our outpatient clinic, a total of 322 women aged between 18 and 65 years and meeting the requirements of MS were enrolled. All the patients were asked to fill out a questionnaire on metabolic TCM syndrome groups and a questionnaire on the QOL, the Medical Outcomes Study (MOS Short Form-12 (SF-12. Data of biochemical characteristics were collected at the same time. The present study showed MS women in TCM syndrome groups had significantly lower physical and mental component scores in SF-12 compared with those not in TCM syndrome groups. We also found MS patients in TCM syndrome groups, except Kidney Deficiency syndrome, showed higher body mass indexes, waist circumference, and hip circumference. However, there was almost no difference in most biochemical characteristics between TCM syndrome groups. The MS patients diagnosed as belonging to TCM syndrome groups had poor QOL.

    Full Text Available Background. To simplify traditional Chinese medicine syndrome differentiation and allow researchers to master syndrome differentiation for hypertension, this paper retrospectively studied the literature and analyzed syndrome elements corresponding to hypertension syndromes. Methods. Six databases including PubMed, EMBASE, Chinese Bio-Medical Literature Database, Chinese National Knowledge Infrastructure, Chinese Scientific Journal Database, and Wan-fang Data were searched from 1/January/2003 to 30/October/2013. We included all clinical literature testing hypertension syndromes and retrospectively studied the hypertension literature published from 2003 to 2013. Descriptive statistics calculated frequencies and percentages. Results. 13,272 patients with essential hypertension were included. Clinical features of hypertension could be attributed to 11 kinds of syndrome factors. Among them, seven syndrome factors were excess, while four syndrome factors were deficient. Syndrome targets were mainly in the liver and related to the kidney and spleen. There were 33 combination syndromes. Frequency of single-factor syndromes was 31.77% and frequency of two-factor syndromes was 62.26%. Conclusions. Excess syndrome factors of hypertension patients include yang hyperactivity, blood stasis, phlegm turbidity, internal dampness, and internal fire. Deficient syndrome factors of hypertension patients are yin deficiency and yang deficiency. Yin deficiency with yang hyperactivity, phlegm-dampness retention, and deficiency of both yin and yang were the three most common syndromes in clinical combination.

    To explore the composition characteristics of traditional Chinese medicine (TCM) syndromes in patients with acute ischemic stroke of yin or yang syndrome by investigating the characteristics of TCM syndromes at different periods after onset. One thousand two hundred and forty-six patients with acute ischemic stroke were admitted in twenty hospitals. According to the "diagnostic criteria of syndrome differentiation of stroke", the characteristics of syndromes in the patients were investigated at the periods of 1-3 days, 4-10 days and 11-30 days after they had ischemic stroke. General distribution of six basic syndromes was compared between the patients with yin syndrome and the patients with yang syndrome at the three periods. The six basic syndromes were wind syndrome, pathogenic fire syndrome, phlegm syndrome, blood stasis syndrome, qi deficiency syndrome, and syndrome of yin deficiency and yang hyperactivity. The percentages of wind, pathogenic fire, and phlegm syndromes in the patients were decreased at the period of 11-30 days as compared with the period of 1-3 days (87.1% vs 79.3%, 52.1% vs 38.7% and 67.1% vs 57.4% respectively, P0.05). There were no differences in the distribution of yin and yang syndromes among the three periods (P>0.05). The percentages of syndromes of wind, pathogenic fire, phlegm, and yin deficiency and yang hyperactivity were higher (Pfour or five syndromes were higher, and the percentages of single-syndromes and complex syndromes of two syndromes were lower in patients with yang syndrome than in patients with yin syndrome (P<0.05, P<0.01). The most frequent complex syndromes in patients with yin syndrome were complex syndrome of wind, phlegm, blood stasis and qi deficiency, and complex syndrome of wind, phlegm and qi deficiency; while the most frequent complex syndromes in patients with yang syndrome were complex syndrome of wind, pathogenic fire, phlegm and qi deficiency, and complex syndrome of wind, pathogenic fire and phlegm.

    Chronic pain is more prevalent in indigenous populations who often prefer traditional remedies over allopathic drugs. Our objective was to investigate the traditional uses of medicinal plants from the Canadian boreal forest for the management of chronic pain syndromes. We reviewed the most extensive database on medicinal plants used by aboriginal people of the Canadian boreal forest to investigate the plants used in the management of 3 of the most common chronic pain syndromes: arthritis/rheumatism; back pain; and headache/migraine. We also reviewed the pharmacology and phytochemistry literature to investigate concordance with indigenous knowledge. A total of 114 medicinal plant species were reported, of which 27 (23.5%) were used to treat more than 1 chronic pain syndrome. Pharmacological or phytochemical evidence to explain plant function as chronic pain remedy was available in the literature for only 38 species (33%), with several species reported to have anti-inflammatory and analgesic properties effective in treating chronic pain syndromes. Our study showed the potential of boreal plants as alternative and complementary medicines for the treatment of chronic pain syndromes that could be enhanced by further research on efficacy and safety issues. © 2015 World Institute of Pain.

    Full Text Available The etiology of chronic fatigue syndrome (CFS is unknown and no conventional medicine therapies are available. This report presents a clinical case of a patient suffering from CFS who was cured by traditional Korean medicine. A 33-year-old female patient had to take time off work because of terrible fatigue symptoms that did not respond to conventional treatments. Her disorder was significantly reduced by herbal medicine, acupuncture, and moxibustion. Changes in fatigue severity were evaluated using a visual analog scale (VAS and a numerical rating scale (NRS. NRS and VAS scores decreased from 70 and 8.1 to 37 and 3.7, respectively, during 3 months. This case reveals the therapeutic potential of traditional Korean medicine for CFS and fatigue-associated disorders.

    Given the challenges in exploring lifelong therapy with little side effect for human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) cases, there is increasing interest in developing traditional Chinese medicine (TCM) treatments based on specific TCM syndrome. However, there are few objective and biological evidences for classification and diagnosis of HIV/AIDS TCM syndromes to date. In this study, iTRAQ-2DLC-MS/MS coupled with bioinformatics were firstly employed for comparative proteomic profiling of top popular TCM syndromes of HIV/AIDS: accumulation of heat-toxicity (AHT) and Yang deficiency of spleen and kidney (YDSK). It was found that for the two TCM syndromes, the identified differential expressed proteins (DEPs) as well as their biological function distributions and participation in signaling pathways were significantly different, providing biological evidence for the classification of HIV/AIDS TCM syndromes. Furthermore, the TCM syndrome-specific DEPs were confirmed as biomarkers based on western blot analyses, including FN1, GPX3, KRT10 for AHT and RBP4, ApoE, KNG1 for YDSK. These biomarkers also biologically linked with the specific TCM syndrome closely. Thus the clinical and biological basis for differentiation and diagnosis of HIV/AIDs TCM syndromes were provided for the first time, providing more opportunities for stable exertion and better application of TCM efficacy and superiority in HIV/AIDS treatment.

    This study aims to investigate whether integration of traditional Chinese medicine and modern medicine has advantage in achieving the improved diagnosis and treatment of knee osteoarthritis. 90 patients with knee osteoarthritis were selected from The Department of Minimal Invasive Joint of The Third Affiliated Hospital of Beijing University of Chinese Medicine from June 2013 to June 2015. They were divided into 3 groups with 30 cases per group in accordance to the syndrome differentiation of traditional Chinese medicine. The patients underwent arthroscopic surgery, and we categorized the patients having the same characterization in each group, and those having distinct difference into the three groups. Based on the arthroscopic analysis, we performed analysis of statistical data in order to analyze the relation between knee osteoarthritis under arthroscope and traditional Chinese medicine syndromes. There are three syndromes according to traditional Chinese medicine that can be categorized into various different groups. The synovial proliferation can be seen mostly in the syndrome of stagnation of blood stasis. The slight damage of knee joint cartilage can be seen in the syndrome of yang deficiency and cold stagnation, the severe one in the syndrome of kidney-marrow deficiency. We found that there are different pathological expressions with the various degree of the tissues damage at the knee and we categorized the knee according to their syndrome. For knee osteoarthritis, different syndromes of traditional Chinese medicine presents different tissues pathological changes at the knee joint under arthroscopy, which will provide objective basis for the diagnosis of this medical condition.

    To study the characteristics of traditional Chinese medicine (TCM) syndrome factors of patients from different areas of China with human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome (AIDS). A cross-sectional investigation study was conducted in Henan, Guangdong and Yunnan Provinces and Xinjiang Uygur Autonomous Region of China from October 2008 to August 2010. Based on literature review and expert opinion, a clinical questionnaire of TCM syndromes was drawn up. This survey was carried out after the investigators were professionally trained. Wenfeng III Auxiliary Diagnosis and Treat System of TCM was used to analyze the frequencies of AIDS patients' signs and symptoms with scores above 70 of syndrome factors respectively. Based on this work, syndrome factors of AIDS were analyzed in different areas. There were 608 HIV/AIDS cases investigated from October 2008 to August 2010 in total; among them, 276 cases were from Henan, 126 cases from Guangdong, 120 cases from Xinjiang and 86 cases from Yunnan. The results of syndrome factor analysis indicated that the syndromes of four provinces were similar. HIV/AIDS patients in the four areas exhibited qi deficiency, blood deficiency, yin deficiency, yang deficiency, dampness, phlegm, qi stagnation and essence deficiency syndromes. Patients in each area also had their own characteristics, such as that the scores of dampness of Guangdong and yin deficiency of Xinjiang were higher than the other syndromes, whereas the scores of Henan Province were higher than the other areas. AIDS patients had higher scores of syndromes than HIV-infected patients. HIV/AIDS patients from different areas had similar syndrome elements. The theory of "AIDS toxin injuring primordial qi" can sum up the TCM etiology and pathogenesis of HIV/AIDS.

    Branding refers to a traditional practice of creating 'therapeutic' burns with hot iron rods over the skin in order to treat various diseases. Although branding is a harmful practice for the body, it has been used for various illnesses including physiologic jaundice in newborns, pneumonia, and convulsions. It causes serious morbidity and delays seeking proper medical care in neonates. Innovations of modern medicine and the use of evidence-based medicine should be preferred instead of these traditional practices. We present a branded mature newborn baby who was diagnosed as having adrenocorticotropic hormone resistance syndrome. This problem is very rare in Turkey; however, it is a very important health issue and has social aspects. Therefore, this case is presented to increase awareness.

    We investigated the effectiveness of cupping, a traditional method of treating musculoskeletal pain, in patients with carpal tunnel syndrome (CTS) in an open randomized trial. n = 52 outpatients (58.5 +/- 8.0 years) with neurologically confirmed CTS were randomly assigned to either a verum (n = 26) or a control group (n = 26). Verum patients were treated with a single application of wet cupping, and control patients with a single local application of heat within the region overlying the trapezius muscle. Patients were followed up on day 7 after treatment. The primary outcome, severity of CTS symptoms (VAS), was reduced from 61.5 +/- 20.5 to 24.6 +/- 22.7 mm at day 7 in the cupping group and from 67.1 +/- 20.2 to 51.7 +/- 23.9 mm in the control group [group difference -24.5mm (95%CI -36.1; -2.9, P cupping therapy may be effective in relieving the pain and other symptoms related to CTS. The efficacy of cupping in the long-term management of CTS and related mechanisms remains to be clarified. The results of a randomized trial on the clinical effects of traditional cupping therapy in patients with carpal tunnel syndrome are presented. Cupping of segmentally related shoulder zones appears to alleviate the symptoms of carpal tunnel syndrome.

    Polycystic ovary syndrome (PCOS) is a common and complex endocrinopathy with reproductive, metabolic, and psychological features and significantly increased cardiometabolic risks. PCOS is underpinned by inherent insulin resistance and hyperandrogenism. Obesity, more common in PCOS, plays an important role in the pathophysiology, exacerbating hyperinsulinaemia and hyperandrogenism, leading to recommended first-line lifestyle intervention. Significant traditional and non-traditional risk factors are implicated in PCOS in addition to obesity-exacerbated cardiometabolic risks and are explored in this review to promote the understanding of this common metabolic and reproductive condition. © 2016 S.

    2004-01-01

    Full Text Available The so-called functional somatic syndromes comprise a group of disorders that are primarily symptom-based, multisystemic in presentation and probably involve alterations in mind-brain-body interactions. The emerging neurobiological models of allostasis/allostatic load and of the emotional motor system show striking similarities with concepts used by Traditional Chinese Medicine (TCM to understand the functional somatic disorders and their underlying pathogenesis. These models incorporate a macroscopic perspective, accounting for the toll of acute and chronic traumas, physical and emotional stressors and the complex interactions between the mind, brain and body. The convergence of these biomedical models with the ancient paradigm of TCM may provide a new insight into scientifically verifiable diagnostic and therapeutic approaches for these common disorders.

    Full Text Available Constipation is a common problem in advanced cancer patients; however, specific clinical guidelines on traditional Chinese medicine (TCM syndrome (Zhang are not yet available. In this cross-sectional study, the TCM syndromes distribution and their common symptoms and signs among 225 constipated advanced cancer patients were determined. Results showed that 127 patients (56.4% and 7 patients (3.1% were in deficient and excessive patterns, respectively, while 91 patients (40.4% were in deficiency-excess complex. The distributions of the five syndromes were: Qi deficiency (93.3%, Qi stagnation (40.0%, blood (Yin deficiency (28.9%, Yang deficiency (22.2%, and excess heat (5.8%. Furthermore, age, functional status, and level of blood haemoglobin were factors related to the type of TCM syndrome. A TCM prescription with the functions on replenishing the Deficiency, redirecting the flow of Qi stagnation and moistening the dryness caused by the blood (Yin deficiency can be made for the treatment of advance cancer patients with constipation. Robust trials are urgently needed for further justifying its efficacy and safety in evidence-based approaches.

    To investigate the distribution of traditional Chinese medicine (TCM) Syndromes of diabetic retinopathy and explore the correlation between various symptoms. Based on the literature in databases of China Journal Full-text Database (CNKI), Wanfang database, VIP network, China biomedical literature database (CBM) and PubMed, SPSS 20.0 and IBM SPSS Modeler 14.1 software were used to analyze the location of disease, symptoms, tongue and pulse, and syndrome type distribution through frequency statistics. In addition, association rule algorithm was used to explore the basic rules for underlying symptoms combinations of diabetic retinopathy. A total of 560 articles were retrieved, and a total of 240 articles met the inclusion and exclusion criteria. In these documents, 62 types of TCM syndromes were found, involving 9 820 cases, 201 symptoms, 29 tongue conditions, and 36 pulses conditions; the first two locations for the disease were liver and kidney. Then the association rule analysis of high frequency symptoms was used to dig out 15 groups of latent syndrome, and 3 underlying symptom combinations among high frequency symptoms, tongue conditions and pulse conditions. The results of the study showed that Qi and yin deficiency was most common for the diabetic retinopathy, and the location of the disease was closely related to liver and kidney. In addition, these high-frequency symptoms and tongue conditions, pulse conditions, and underlying symptom combinations can occur as main symptoms at diagnosis, providing reference for us to study the epidemiology of PRO scale of the disease. They can also increase the weight of these symptoms directly as the main symptoms, which can be also used as an alternative entry pool for TCM syndrome diagnostic scale, laying foundation for the construction and optimization of TCM symptom database of diabetic retinopathy.

    BACKGROUND & AIMS: Patients with bi-allelic germline mutations in mismatch repair (MMR) genes (MLH1, MSH2, MSH6, or PMS2) develop a rare but severe variant of Lynch syndrome called constitutional MMR deficiency (CMMRD). This syndrome is characterized by early-onset colorectal cancers, lymphomas...... or leukemias, and brain tumors. There is no satisfactory method for diagnosis of CMMRD because screens for mutations in MMR genes are noninformative for 30% of patients. MMR-deficient cancer cells are resistant to genotoxic agents and have microsatellite instability (MSI), due to accumulation of errors...

    Full Text Available Impaired cardiac function leads to activation of the neurohumoral axis, sodium and water retention, congestion and ultimately impaired kidney function. This sequence of events has been termed the Cardiorenal Syndrome. This is different from the increase in cardiovascular complications which occur with primary kidney disease, that is, the so-called Renocardiac Syndrome. The present review discusses the pathogenesis of the Cardiorenal Syndrome followed by the benefits and potential deleterious effects of pharmacological agents that have been used in this setting. The agents discussed are diuretics, aquaretics, natriuretic peptides, vasodilators, inotropes and adenosine α1 receptor antagonists. The potential role of ultrafiltration is also briefly discussed.

    A new emerging disease in shrimp, first reported in 2009, was initially named early mortality syndrome (EMS). In 2011, a more descriptive name for the acute phase of the disease was proposed as acute hepatopancreatic necrosis syndrome (AHPNS). Affecting both Pacific white shrimp Penaeus vannamei and black tiger shrimp P. monodon, the disease has caused significant losses in Southeast Asian shrimp farms. AHPNS was first classified as idiopathic because no specific causative agent had been identified. However, in early 2013, the Aquaculture Pathology Laboratory at the University of Arizona was able to isolate the causative agent of AHPNS in pure culture. Immersion challenge tests were employed for infectivity studies, which induced 100% mortality with typical AHPNS pathology to experimental shrimp exposed to the pathogenic agent. Subsequent histological analyses showed that AHPNS lesions were experimentally induced in the laboratory and were identical to those found in AHPNS-infected shrimp samples collected from the endemic areas. Bacterial isolation from the experimentally infected shrimp enabled recovery of the same bacterial colony type found in field samples. In 3 separate immersion tests, using the recovered isolate from the AHPNS-positive shrimp, the same AHPNS pathology was reproduced in experimental shrimp with consistent results. Hence, AHPNS has a bacterial etiology and Koch's Postulates have been satisfied in laboratory challenge studies with the isolate, which has been identified as a member of the Vibrio harveyi clade, most closely related to V. parahemolyticus.

    2011-01-01

    Popliteal vascular entrapment syndrome is caused by aberrations or hypertrophy of the gastrocnemius muscles, which compress the neurovascular structures of the popliteal fossa, leading to symptoms of vascular and degeneration as well as aneurysm formation. Imaging of popliteal vascular entrapment may be performed with ultrasound, magnetic resonance imaging (MRI), computed tomography angiography, and conventional angiography. The use of blood-pool contrast agents in MRI when popliteal vascular entrapment is suspected offers the possibility to perform vascular imaging with first-pass magnetic resonance angiographic, high-resolution, steady-state imaging and allows functional tests all within one examination with a single dose of contrast agent. We present imaging findings in a case of symptomatic popliteal vein entrapment diagnosed by the use of blood pool contrast-enhanced MRI.

    Full Text Available The circumstance of winter disease phenomenon in intensively reared sea bream (Sparus aurata L. has been described. It’s occurence in Mediterranean has been registered and reported by several authors. The aim of this paper is to contribute to the comprehension on the aethiology of this syndrome which is causing significant losses in one year old cultured fish. Different types of commercial diets were introduced during 1994/95 rearing season to the sea bream reared in floating cages. The feeds were displaying differences in energetic compound level and vitamin A, D3 and E content. Health difficulties and mortality in the observed fish groups at the beginning of the problem, did not indicate any biotic agent as being responsible for such condition. Clinical features and mortality in the groups affected by winter disease syndrome were increasing by low sea temperature and correlating with feeding period by food containing low levels of protein, lipids and vitamins. Pathological findings were in particularly related to the organs involved in digestion. Growth rate was characteristic for the group that were suffering winter disease, where increasing in length was not followed by body weight. Clinical signs, simptomathology related to the organs involved in digestion, liver histology analyses, weight losses and pattern of weight and length relation, correlation between used feeds and occurrence of winter disease, implicated nutrition as one of most possible ethiological agent of this condition. Nutritional interventions applied contributed in comprehension of the winter disease syndrome. The relationship between nutritional requirements, particularly regerding autumn-winter period, has been researched and analyzed. The results approved our basic hypothesis.

  14. The traditional Korean dietary pattern is associated with decreased risk of metabolic syndrome: findings from the Korean National Health and Nutrition Examination Survey, 1998-2009.

    The traditional Korean diet has several healthy components, including abundant vegetables, fermented foods, a variety of foodstuffs, and a balance of animal and vegetable food intake. Although the traditional Korean diet has many healthy components, few studies have been conducted on the health advantages of the Korean dietary pattern. This study is intended to clarify the relationship between Korean dietary patterns and chronic diseases using the Integrated Korean Dietary Pattern Score (I-KDPS). I-KDPS is an index for measuring Korean dietary patterns based on traditional Korean meals and reflects the complex and multifaceted characteristics of Korean food culture. I-KDPS is composed of seven items to measure the level of balance and adequacy of Korean food consumption, with a maximum score of 60. When I-KDPS was applied to the Korean National Health and Nutrition Examination Survey (1998-2009), a nationwide survey, I-KDPS was closely related to the risk of metabolic syndrome. Even though there were a few differences among the years surveyed, the risk of metabolic syndrome, obesity, hypertension, and hypertriglyceridemia significantly decreased as I-KDPS increased. These results indicate that risk of diseases, including metabolic syndrome, decreases in individuals adhering to traditional Korean dietary patterns in adequate levels and those who eat a balanced diet. The result of this study shows that the traditional Korean table setting, which comprises side dishes, including seasoned vegetables, grilled dishes, and fermented products with cooked rice (bap), soup (guk), and kimchi, contains traits that help prevent metabolic syndrome. I-KDPS coupled with the basic study of the healthfulness of the Korean dietary lifestyle is expected to help establish a foundation for continuous development of health promoting Korean foods and dietary culture.

    Four wild berry species, Amelanchier alnifolia, Viburnum trilobum, Prunus virginiana, and Shepherdia argentea, all integral to the traditional subsistence diet of Native American tribal communities, were evaluated to elucidate phytochemical composition and bioactive properties related to performance and human health. Biological activity was screened using a range of bioassays that assessed the potential for these little-known dietary berries to affect diabetic microvascular complications, hyperglycemia, pro-inflammatory gene expression, and metabolic syndrome symptoms. Nonpolar constituents from berries, including carotenoids, were potent inhibitors of aldose reductase (an enzyme involved in the etiology of diabetic microvascular complications), whereas the polar constituents, mainly phenolic acids, anthocyanins, and proanthocyanidins, were hypoglycemic agents and strong inhibitors of IL-1beta and COX-2 gene expression. Berry samples also showed the ability to modulate lipid metabolism and energy expenditure in a manner consistent with improving metabolic syndrome. The results demonstrate that these berries traditionally consumed by tribal cultures contain a rich array of phytochemicals that have the capacity to promote health and protect against chronic diseases, such as diabetes.

    2018-03-01

    In recent years, there has been an increasing interest in alternative (complementary) treatments of interstitial cystitis/bladder pain syndrome (IC/BPS). This is due both to the high incidence of IC/BPS and to a lack of effectiveness of conventional treatments. One of the directions of alternative therapies is a traditional Chinese medicine using a special diet, various animal and plant-derived medicines, breathing exercises and acupuncture. This review analyzes the accumulated experience in using traditional Chinese medicine in the treatment of patients with IC/BPS. The presented data indicate that these methods appear to be promising, since they are effective in a significant number of patients, lead to an improvement in their quality of life, are non-invasive and well tolerated. However, due to the lack of clinical studies, the efficacy of this treatment modalities needs to be confirmed.

    Full Text Available Abstract Many people with Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS in Namibia have access to antiretroviral drugs but some still use traditional medicines to treat opportunistic infections and offset side-effects from antiretroviral medication. Namibia has a rich biodiversity of indigenous plants that could contain novel anti-HIV agents. However, such medicinal plants have not been identified and properly documented. Various ethnomedicines used to treat HIV/AIDS opportunistic infections have not been scientifically validated for safety and efficacy. These limitations are mostly attributable to the lack of collaboration between biomedical scientists and traditional healers. This paper presents a five-step contextual model for initiating collaboration with Namibian traditional healers in order that candidate plants that may contain novel anti-HIV agents are identified, and traditional medicines used to treat HIV/AIDS opportunistic infections are subjected to scientific validation. The model includes key structures and processes used to initiate collaboration with traditional healers in Namibia; namely, the National Biosciences Forum, a steering committee with the University of Namibia (UNAM as the focal point, a study tour to Zambia and South Africa where other collaborative frameworks were examined, commemorations of the African Traditional Medicine Day (ATMD, and consultations with stakeholders in north-eastern Namibia. Experiences from these structures and processes are discussed. All traditional healers in north-eastern Namibia were willing to collaborate with UNAM in order that their traditional medicines could be subjected to scientific validation. The current study provides a framework for future collaboration with traditional healers and the selection of candidate anti-HIV medicinal plants and ethnomedicines for scientific testing in Namibia.

    Metastatic neuroendocrine tumors (NETs) are associated with carcinoid syndrome that is typically characterized by diarrhea, cutaneous flushing and bronchospasm. Treatment with somatostatin analogues (SSA) improves the symptom burden but a significant proportion of patients stop responding to SSA therapy eventually. Novel agents with the potential to effectively control the symptoms are urgently needed. This article reviews an in-depth analysis of the phase I-III clinical trials determining the clinical rationale for the use of tryptophan hydroxylase inhibitor, telotristat ethyl in patients with well-differentiated metastatic NETs and uncontrolled carcinoid syndrome. Telotristat ethyl has already been approved for the treatment of inadequately controlled carcinoid syndrome symptoms in metastatic NET patients on SSA therapy. Results from multiple phase I-III clinical studies of telotristat ethyl therapy have reported a significant decrease in the daily bowel movement frequency, increase in quality of life and the subsequent decrease in annual health costs related to carcinoid syndrome symptoms in NET patients. The associated decrease in urinary 5-hydroxyindoleacetic acid (u5-HIAA) provides evidence that telotristat ethyl effectively decreases serotonin production, and therefore, offers a rationale to investigate this agent to mitigate serotonin-mediated complications in this patient population, especially cardiac valvular disease or mesenteric fibrosis.

  1. Mechanisms of Anorexia Cancer Cachexia Syndrome and Potential Benefits of Traditional Medicine and Natural Herbs.

    Ming-Hua, Cong; Bao-Hua, Zou; Lei, Yu

    Anorexia cancer cachexia syndrome is prevalent in advanced cancer patients, which is featured by anorexia, decreased dietary intake, body weight loss (skeletal muscle mass loss), and is unable to be reversed by routine nutritional support therapy. Up to now, the main mechanisms involved in cancer cachexia include excessive systemic inflammation, which is represented by increased plasma levels of IL-1, IL-6, TNF-alpha, tumor-induced factors, such as PIF and LMF. These factors eventually act on orexigenic and anorexigenicneurons located in the hypothalamus or protein and lipid metabolism of peripheral tissues, which lead to anorexia, decreased dietary intake, enhanced basic metabolism rate and hypercatabolism. The treatment modality includes early nutritional intervention, physical activity and drug treatment. However, studies about drugs used to treat cachexia are always controversial or merely effective in stimulating appetite and increasing body weight, though not lean body mass. The main target of pharmaceutical treatment is to improve appetite, decrease systemic inflammation and promote anabolic metabolism. Nevertheless, the treatment effectiveness of chemical drugs are not reaching consensus by existing cachexia guidelines. Complementary and alternative medicine (CAM) is recently known as a promising treatment to improve cachaxia status and quality of life of cancer patients. Traditional Chinese medicine (TCM) and natural herbal medicines have been used in the treatment of cancer for thousands of years worldwide, particularly in China. More and more research show that traditional Hanfang (Chinese medicines) and some natural herbs with less side reactions, have the effects of antagonizing pro-inflammatory cytokines, enhancing immune system, inhibiting protein catabolism, boosting the appetite and body weight, which maybe a promising treatment strategy and development tendency for anorexia cancer cachexia syndrome.

    Full Text Available Food poisoning is the one of the main health hazards even today. More than 200 known diseases are transmitted through food. The causes of foodborne illness include viruses, bacteria, parasites, toxins, metals, and prions and the symptoms of foodborne illness range from mild gastroenteritis to life-threatening neurological, hepatic and renal syndromes.The prevention of food poisonings represents very serious task for food manufacturers. Beside food control according to the concept "from the farm to the table" there is increased need for the development of new technology for longer shelf lifes of food. Food fermented by lactic acid bacteria (LAB and traditionally considered to be safe. There are many substances produced by LAB that affect the shelf life of fermented food, by active suppression of poisoning microorganisms growth. Because of that, the LAB is recently considered as bioprotective agents that have important role in food safety.

    Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) has been widely described in many studies conducted thus far. The syndrome incorporates five immune-mediated conditions, all associated with previous exposure to various agents such as vaccines, silicone implants and several others. The emergence of ASIA syndrome is associated with individual genetic predisposition, for instance those carrying HLA-DRB1*01 or HLA-DRB4 and results from exposure to external or endogenous factors triggering autoimmunity. Such factors have been demonstrated as able to induce autoimmunity in both animal models and humans via a variety of proposed mechanisms. In recent years, physicians have become more aware of the existence of ASIA syndrome and the relationship between adjuvants exposure and autoimmunity and more cases are being reported. Accordingly, we have created a registry that includes at present more than 300 ASIA syndrome cases that have been reported by different physicians worldwide, describing various autoimmune conditions induced by diverse adjuvants. In this review, we have summarized the updated literature on ASIA syndrome and the knowledge accumulated since 2013 in order to elucidate the association between the exposure to various adjuvant agents and its possible clinical manifestations. Furthermore, we especially referred to the relationship between ASIA syndrome and systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS).

    Full Text Available Coronary artery disease (CAD is the leading causes of deaths in the world. The differentiation of syndrome (ZHENG is the criterion of diagnosis and therapeutic in TCM. Therefore, syndrome prediction in silico can be improving the performance of treatment. In this paper, we present a Bayesian network framework to construct a high-confidence syndrome predictor based on the optimum subset, that is, collected by Support Vector Machine (SVM feature selection. Syndrome of CAD can be divided into asthenia and sthenia syndromes. According to the hierarchical characteristics of syndrome, we firstly label every case three types of syndrome (asthenia, sthenia, or both to solve several syndromes with some patients. On basis of the three syndromes’ classes, we design SVM feature selection to achieve the optimum symptom subset and compare this subset with Markov blanket feature select using ROC. Using this subset, the six predictors of CAD’s syndrome are constructed by the Bayesian network technique. We also design Naïve Bayes, C4.5 Logistic, Radial basis function (RBF network compared with Bayesian network. In a conclusion, the Bayesian network method based on the optimum symptoms shows a practical method to predict six syndromes of CAD in TCM.

    Chronic atrophic gastritis (CAG) is the precancerous stage of gastric carcinoma. Traditional Chinese Medicine (TCM) has been widely used in treating CAG. This study aimed to reveal core pathogenesis of CAG by validating the TCM syndrome patterns and provide evidence for optimization of treatment strategies. This is a cross-sectional study conducted in 4 hospitals in China. Hierarchical clustering analysis (HCA) and complex system entropy clustering analysis (CSECA) were performed, respectively, to achieve syndrome pattern validation. Based on HCA, 15 common factors were assigned to 6 syndrome patterns: liver depression and spleen deficiency and blood stasis in the stomach collateral, internal harassment of phlegm-heat and blood stasis in the stomach collateral, phlegm-turbidity internal obstruction, spleen yang deficiency, internal harassment of phlegm-heat and spleen deficiency, and spleen qi deficiency. By CSECA, 22 common factors were assigned to 7 syndrome patterns: qi deficiency, qi stagnation, blood stasis, phlegm turbidity, heat, yang deficiency, and yin deficiency. Combination of qi deficiency, qi stagnation, blood stasis, phlegm turbidity, heat, yang deficiency, and yin deficiency may play a crucial role in CAG pathogenesis. In accord with this, treatment strategies by TCM herbal prescriptions should be targeted to regulating qi, activating blood, resolving turbidity, clearing heat, removing toxin, nourishing yin, and warming yang. Further explorations are needed to verify and expand the current conclusions.

    White-nose Syndrome (WNS) is an emerging infectious mycosis that has impacted multiple species of North American bats since its initial discovery in 2006, yet the physiology of the causal agent, the psychrophilic fungus Pseudogymnoascus destructans ( = Geomyces destructans), is not well understood. We investigated the ability of P. destructans to secrete enzymes that could permit environmental growth or affect pathogenesis and compared enzyme activity across several Pseudogymnoascus species isolated from both hibernating bats and cave sediments. We found that P. destructans produced enzymes that could be beneficial in either a pathogenic or saprotrophic context, such as lipases, hemolysins, and urease, as well as chitinase and cellulases, which could aid in saprotrophic growth. The WNS pathogen showed significantly lower activity for urease and endoglucanase compared to con-generic species (Pseudogymnoascus), which may indicate a shift in selective pressure to the detriment of P. destructans' saprotrophic ability. Based on the positive function of multiple saprotrophic enzymes, the causal agent of White-nose Syndrome shows potential for environmental growth on a variety of substrates found in caves, albeit at a reduced level compared to environmental strains. Our data suggest that if P. destructans emerged as an opportunistic infection from an environmental source, co-evolution with its host may have led to a reduced capacity for saprotrophic growth.

    Metabolic syndrome is a disorder based on insulin resistance. Metabolic syndrome is diagnosed by a co-occurrence of three out of five of the following medical conditions: abdominal obesity, elevated blood pressures, elevated glucose, high triglycerides, and low high-density lipoprotein-cholesterol (HDL-C) levels. Clinical implication of metabolic syndrome is that it increases the risk of developing type 2 diabetes and cardiovascular diseases. Prevalence of the metabolic syndrome has increased globally, particularly in the last decade, to the point of being regarded as an epidemic. The prevalence of metabolic syndrome in the USA is estimated to be 34% of adult population. Moreover, increasing rate of metabolic syndrome in developing countries is dramatic. One can speculate that metabolic syndrome is going to induce huge impact on our lives. The metabolic syndrome cannot be treated with a single agent, since it is a multifaceted health problem. A healthy lifestyle including weight reduction is likely most effective in controlling metabolic syndrome. However, it is difficult to initiate and maintain healthy lifestyles, and in particular, with the recidivism of obesity in most patients who lose weight. Next, pharmacological agents that deal with obesity, diabetes, hypertension, and dyslipidemia can be used singly or in combination: anti-obesity drugs, thiazolidinediones, metformin, statins, fibrates, renin-angiotensin system blockers, glucagon like peptide-1 agonists, sodium glucose transporter-2 inhibitors, and some antiplatelet agents such as cilostazol. These drugs have not only their own pharmacologic targets on individual components of metabolic syndrome but some other properties may prove beneficial, i.e. anti-inflammatory and anti-oxidative. This review will describe pathophysiologic features of metabolic syndrome and pharmacologic agents for the treatment of metabolic syndrome, which are currently available.

    Full Text Available Pinky Agarwal1, Alida Griffith1, Henry R Costantino2, Narendra Vaish31Booth Gardner Parkinson’s Center, Kirkland, WA, USA; 2Costantino Consulting, Woodinville, WA, USA; 3Kirkland, WA, USAAbstract: Restless legs syndrome (RLS is a sleep-related movement disorder commonly involving an unpleasant urge to move the limbs, typically the legs. Dopaminergic agents represent the first-line therapy for RLS; however, long-term use of such drugs results in worsening symptoms due to “augmentation” or other adverse events. Gabapentin, an analog of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA, is an anticonvulsant/analgesic agent. Gabapentin is only mildly effective in relieving RLS symptoms, perhaps a result of its poor absorption from the gastrointestinal (GI tract. Gabapentin enacarbil is a prodrug of gabapentin specifically designed to enhance absorption via the GI tract, and hence provide improved circulating levels of gabapentin on metabolism. Clinical trials to date have demonstrated favorable safety and (compared to traditional gabapentin improved pharmacokinetics and efficacy in treating RLS symptoms. Thus, gabapentin enacarbil may prove to be a useful drug in treating RLS. An application of gabapentin enacarbil for treatment of RLS is currently pending with FDA for approval.Keywords: restless legs syndrome, gabapentin enacarbil, movement disorder

    Full Text Available The present study aims at examining the effects of argan oil on the three main cardiovascular risk factors associated with metabolic syndrome (hypertension, insulin resistance and obesity and on one of its main complications, neuropathic pain. Male Sprague-Dawley rats had free access to a drinking solution containing 10% d-glucose or tap water for 12 weeks. The effect of argan oil was compared to that of corn oil given daily by gavage during 12 weeks in glucose-fed rats. Glucose-fed rats showed increases in systolic blood pressure, epididymal fat, plasma levels of triglycerides, leptin, glucose and insulin, insulin resistance, tactile and cold allodynia in association with a rise in superoxide anion production and NADPH oxidase activity in the thoracic aorta, epididymal fat and gastrocnemius muscle. Glucose-fed rats also showed rises in B1 receptor protein expression in aorta and gastrocnemius muscle. Argan oil prevented or significantly reduced all those anomalies with an induction in plasma adiponectin levels. In contrast, the same treatment with corn oil had a positive impact only on triglycerides, leptin, adiponectin and insulin resistance. These data are the first to suggest that argan oil is an effective nutri-therapeutic agent to prevent the cardiovascular risk factors and complications associated with metabolic syndrome.

    Full Text Available Mars500 study was a psychological and physiological isolation experiment conducted by Russia, the European Space Agency, and China, in preparation for an unspecified future manned spaceflight to the planet Mars. Its intention was to yield valuable psychological and medical data on the effects of the planned long-term deep space mission. In this paper, we present data mining methods to mine medical data collected from the crew consisting of six spaceman volunteers. The synthesis of the four diagnostic methods of TCM, inspection, listening, inquiry, and palpation, is used in our syndrome differentiation. We adopt statistics method to describe the syndrome factor regular pattern of spaceman volunteers. Hybrid optimization based multilabel (HOML is used as feature selection method and multilabel k-nearest neighbors (ML-KNN is applied. According to the syndrome factor statistical result, we find that qi deficiency is a base syndrome pattern throughout the entire experiment process and, at the same time, there are different associated syndromes such as liver depression, spleen deficiency, dampness stagnancy, and yin deficiency, due to differences of individual situation. With feature selection, we screen out ten key factors which are essential to syndrome differentiation in TCM. The average precision of multilabel classification model reaches 80%.

    Cancer-related anorexia syndrome (CACS) is one of the main causes for death at present as well as a syndrome seriously harming patients' quality of life, treatment effect and survival time. In current clinical researches, there are fewer reports about empirical traditional Chinese medicine(TCM) prescriptions and patent prescriptions treating CACS, and prescription rules are rarely analyzed in a systematic manner. As the hidden rules are not excavated, it is hard to have an innovative discovery and knowledge of clinical medication. In this paper, the grey screening method combined with the multivariate statistical method was used to build the ″CACS prescriptions database″. Based on the database, totally 359 prescriptions were selected, the frequency of herbs in prescription was determined, and commonly combined drugs were evolved into 4 new prescriptions for different syndromes. Prescriptions of TCM in treatment of CACS gave priority to benefiting qi for strengthening spleen, also laid emphasis on replenishing kidney essence, dispersing stagnated liver-qi and dispersing lung-qi. Moreover, interdependence and mutual promotion of yin and yang should be taken into account to reflect TCM's holism and theory for treatment based on syndrome differentiation. The grey screening method, as a valuable traditional Chinese medicine research-supporting method, can be used to subjectively and objectively analyze prescription rules; and the new prescriptions can provide reference for the clinical use of TCM for treating CACS and the drug development.

    To observe clinical manifestations, behavioral characteristics, and effects of rehabilitation on a patient with pusher syndrome and unilateral spatial neglect caused by right thalamic hemorrhage. Assessment of pusher syndrome was made by the Scale for Contraversive pushing (SCP), and unilateral spatial neglect syndrome was diagnosed using line cancellation, letter and star cancellation, line bisection tests and copy and continuation of graphic sequence test. Behavioral therapy, occupational therapy, reading training and traditional Chinese medicine methods were adopted for treatment of pusher syndrome and unilateral spatial neglect. The patient showed typical pusher syndrome and unilateral spatial neglect symptoms. The pusher syndrome and unilateral spatial neglect symptoms were significantly improved following rehabilitation treatments. Pusher syndrome and unilateral spatial neglect syndrome occurred simultaneously after right thalamic hemorrhage. Early rehabilitation therapy can reduce the symptoms of pusher syndrome and unilateral spatial neglect syndrome and improve motor function.

    Myasthenia gravis (MG) is a kind of autoimmune disease induced by transferring dysfunction of neuromuscular junction. In the present study, we developed an integrated therapy combined with traditional Chinese medicine and immuno suppressive agents to seek for an effective treatment of MG. 220 MG patients were randomly divided into two groups with different therapies. Plasma levels of acetylcholine receptors antibodies (AchRAb) and CD4+CD25+ regulatory T cells (CD4+CD25+Treg) were conducted through ELISA and flow cytometry. The amount of AchRAb (8.52±0.96 vs. 5.22±0.46) and CD4+CD25+Treg (1.94±1.21 vs. 3.21±0.96) in Group A receiving integrated therapy were significantly improved compared with Group B; the clinical performance of group treated with the integrated therapy was also much better. The integrated therapy in the present study could significantly improve the condition of MG with high recovery rate and low recurrence rate, which can be employed in future clinical treatment of MG.

    Some studies have proven the antioxidant and antimicrobial potency of chestnut flowers both in the raw matrix and after extraction, and the consumption of their decoctions has been related to beneficial effects towards health. In recent years, due to controversy and ambiguous legislation of chemical conservatives, plant extracts have been successfully used as functionalizing agents in different matrixes by displaying their various beneficial effects towards the foodstuff and/or the consumer. In this paper, decoctions of chestnut flowers as well as the dried flower were added to Portuguese traditional cakes that were then stored for 15 and 30 days, after which they were analysed for their antioxidant potential. The results were analysed by means of a 2 way ANOVA and a linear discriminant analysis, concluding that storage time had a slightly higher influence on alteration of the antioxidant activity. DPPH and TBARS were the most improved parameters, regardless of the concentration added.

    2016-06-01

    Nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome (Gorlin syndrome), is a rare autosomal dominantly inherited disorder that is characterized by development of basal cell carcinomas from a young age. Other distinguishing clinical features are seen in a majority of patients, and include keratocystic odontogenic tumors (formerly odontogenic keratocysts) as well as dyskeratotic palmar and plantar pitting. A range of skeletal and other developmental abnormalities are also often seen. The disorder is caused by defects in hedgehog signaling which result in constitutive pathway activity and tumor cell proliferation. As sporadic basal cell carcinomas also commonly harbor hedgehog pathway aberrations, therapeutic agents targeting key signaling constituents have been developed and tested against advanced sporadically occurring tumors or syndromic disease, leading in 2013 to FDA approval of the first hedgehog pathway-targeted small molecule, vismodegib. The elucidation of the molecular pathogenesis of nevoid basal cell carcinoma syndrome has resulted in further understanding of the most common human malignancy.

    Full Text Available Keishibukuryogan (KBG; Guizhi-Fuling-Wan in Chinese is one of the Kampo (Japanese traditional medicines used to treat patients with climacteric syndrome. KBG can be used by patients who cannot undergo hormone replacement therapy due to a history of breast cancer. We evaluated whether cytosine-adenine (CA repeat polymorphism of the estrogen receptor β gene can be a predictor of the beneficial effect of KBG on climacteric syndrome. We also investigated the relationship between CA repeat polymorphism, the patients’ profiles, and the therapeutic effect. We found that CA was an SS, SL, or LL genotype according to the number of repeats. We studied 39 consecutive patients with climacteric disorders who took KBG for 12 weeks. The diagnosis of climacteric disorders was made on the basis of the Kupperman index. KBG significantly improved the patients’ climacteric symptoms (i.e., vasomotor symptoms in the patients with the LL genotype and melancholia in the patients with the SL genotype. No relationship between the patients’ profiles and CA repeat polymorphism was recognized. CA repeat polymorphism could thus be a potential biomarker to predict the efficacy of KBG in climacteric syndrome, and its use will help to reduce the cost of treating this syndrome by focusing the administration of KBG on those most likely to benefit from it.

    Full Text Available The objective of this case study was to investigate the effectiveness of Chinese medicine in treating Tourette's syndrome. Tourette's syndrome is a childhood- onset disorder that is characterized by sudden, involuntary movements or tics. The participant in this study was a 33-year-old male who had been diagnosed with Tourette's syndrome at the age of 9 years. His major complaints included facial tics, shoulder shrugging, and clearing the throat. Using a combination of acupuncture, herbs, Gua-Sha, and lifestyle changes once a week for 35 treatments, all the symptoms were reduced by 70%, as reported by the patient. In this case, the results indicated that Chinese medicine was able to minimize the symptoms of Tourette's syndrome. Further investigation is needed to support this argument. Tourette's syndrome, which was first described in 1885 by a French physician named Gilles de la Tourette, is characterized by facial tics, involuntary body movements from the head to the extremities, or vocal tics, and it usually has its onset in childhood. It is a neuropsychiatric disorder. The treatment for Tourette's syndrome is based on pharmacological treatment, behavior treatment, and deep brain stimulation. Unfortunately, none of these could completely control the symptoms; furthermore, antipsychiatric drugs might cause additional side effects, such as Parkinson symptoms, tardive dyskinesia, and metabolic disturbances. Finding acupuncture and oriental medicine literature on treatment of Tourette's syndrome was difficult, especially that written in English. Some research papers that have been translated into English indicated that Chinese herbs and acupuncture could reduce the tics significantly. For example, a study by Dr Pao-Hua Lin reported the significant effects of using acupuncture and oriental medicine in treating 1000 Tourette's syndrome cases. This case was treated to further investigate the principles of Dr Lin's study.

    The smart navigation system that refers to real-time traffic data is believed to be superior to traditional navigation systems. To verify this belief, we created an agent-based traffic model and examined the effect of changing market share of the traditional shortest-travel-time algorithm based navigation and the smart navigation system. We tested our model on the grid and actual metropolitan road network structures. The result reveals that the traditional navigation system have better performance than the smart one as the market share of the smart navigation system exceeds a critical value, which is contrary to conventional expectation. We suggest that the superiority inversion between agent groups is strongly related to the traffic weight function form, and is general. We also found that the relationship of market share, traffic flow density and travel time is determined by the combination of congestion avoidance behavior of the smartly navigated agents and the inefficiency of shortest-travel-time based navigated agents. Our results can be interpreted with the minority game and extended to the diverse topics of opinion dynamics.

    It is not common for a patient who survives cardiac arrest to experience significant neurologic impairment such as acute and chronic post-hypoxic myoclonus, known as Lance-Adams syndrome. This syndrome is predominantly characterized by myoclonus that starts days to weeks after cardiopulmonary resuscitation in patients who regained consciousness. Although several cases of LAS were reported, the decisive treatment method has not been established. We report a 43 year old man with Lance-Adams syndrome who showed long-term improvement through treatment with anti-myoclonic agents and participation in a rehabilitation program.

    Background: Mucilage compounds are pharmaceutically important polysaccharides that have an extensive range of applications, including binding agents, thickeners, water retention agents, emulsion stabilizers, suspending agents, disintegrates, film formers, and gelling agents. A historical approach to medical science written by Iranian scholars could help in identifying excellent ideas and provide valuable information in this field for proper application. The aim of the current study was to introduce some mucilage uses derived from traditional Persian medicine (TPM). Methods: In this literature review, we assessed a few main traditional manuscripts of Iranian medicine, including the books Al Havi, Canon of Medicine, Qarabadine-kabir, Zakhireh-ye Khwarazm shahi, Tuhfat ul-Momineen and Makhzan-ul-Adwiah. The word “loab” in the aforementioned books were searched and all data about mucilage compounds were collected. Results: The use of medicinal plants containing mucilage in Iran dates back to ancient times. In traditional Persian manuscripts, mucilage is one of the most cited applications of medicinal plants for therapeutic objectives. There are various mucilage-producing plants in TPM such as Malva silvestris, Linum usitissimum, Althaea officinalis, Plantago psyllium, Descureania sophia and Ziziphus vulgaris. They have been used traditionally via oral or topical routes for respiratory, gastrointestinal, urinary, musculoskeletal, and genital systems as well as skin disorders. Certain applications are unique and promising for today’s chronic ailments. Conclusion: A scientific assessment of these valuable manuscripts would provide a better insight into the thoughts of the past sages and applicable for clinical use of the mucilage compounds. This may lead to research opportunities in the future. PMID:27840507

  9. Reliable multi-label learning via conformal predictor and random forest for syndrome differentiation of chronic fatigue in traditional Chinese medicine.

    Huazhen Wang

    Full Text Available OBJECTIVE: Chronic Fatigue (CF still remains unclear about its etiology, pathophysiology, nomenclature and diagnostic criteria in the medical community. Traditional Chinese medicine (TCM adopts a unique diagnostic method, namely 'bian zheng lun zhi' or syndrome differentiation, to diagnose the CF with a set of syndrome factors, which can be regarded as the Multi-Label Learning (MLL problem in the machine learning literature. To obtain an effective and reliable diagnostic tool, we use Conformal Predictor (CP, Random Forest (RF and Problem Transformation method (PT for the syndrome differentiation of CF. METHODS AND MATERIALS: In this work, using PT method, CP-RF is extended to handle MLL problem. CP-RF applies RF to measure the confidence level (p-value of each label being the true label, and then selects multiple labels whose p-values are larger than the pre-defined significance level as the region prediction. In this paper, we compare the proposed CP-RF with typical CP-NBC(Naïve Bayes Classifier, CP-KNN(K-Nearest Neighbors and ML-KNN on CF dataset, which consists of 736 cases. Specifically, 95 symptoms are used to identify CF, and four syndrome factors are employed in the syndrome differentiation, including 'spleen deficiency', 'heart deficiency', 'liver stagnation' and 'qi deficiency'. THE RESULTS: CP-RF demonstrates an outstanding performance beyond CP-NBC, CP-KNN and ML-KNN under the general metrics of subset accuracy, hamming loss, one-error, coverage, ranking loss and average precision. Furthermore, the performance of CP-RF remains steady at the large scale of confidence levels from 80% to 100%, which indicates its robustness to the threshold determination. In addition, the confidence evaluation provided by CP is valid and well-calibrated. CONCLUSION: CP-RF not only offers outstanding performance but also provides valid confidence evaluation for the CF syndrome differentiation. It would be well applicable to TCM practitioners and

    Patients with bi-allelic germline mutations in mismatch repair (MMR) genes (MLH1, MSH2, MSH6, or PMS2) develop a rare but severe variant of Lynch syndrome called constitutional MMR deficiency (CMMRD). This syndrome is characterized by early-onset colorectal cancers, lymphomas or leukemias, and brain tumors. There is no satisfactory method for diagnosis of CMMRD because screens for mutations in MMR genes are noninformative for 30% of patients. MMR-deficient cancer cells are resistant to genotoxic agents and have microsatellite instability (MSI), due to accumulation of errors in repetitive DNA sequences. We investigated whether these features could be used to identify patients with CMMRD. We examined MSI by PCR analysis and tolerance to methylating or thiopurine agents (functional characteristics of MMR-deficient tumor cells) in lymphoblastoid cells (LCs) from 3 patients with CMMRD and 5 individuals with MMR-proficient LCs (controls). Using these assays, we defined experimental parameters that allowed discrimination of a series of 14 patients with CMMRD from 52 controls (training set). We then used the same parameters to assess 23 patients with clinical but not genetic features of CMMRD. In the training set, we identified parameters, based on MSI and LC tolerance to methylation, that detected patients with CMMRD vs controls with 100% sensitivity and 100% specificity. Among 23 patients suspected of having CMMRD, 6 had MSI and LC tolerance to methylation (CMMRD highly probable), 15 had neither MSI nor LC tolerance to methylation (unlikely to have CMMRD), and 2 were considered doubtful for CMMRD based on having only 1 of the 2 features. The presence of MSI and tolerance to methylation in LCs identified patients with CMMRD with 100% sensitivity and specificity. These features could be used in diagnosis of patients.

    Diehl, K B

    1996-10-01

    So many topical antifungal agents have been introduced that it has become very difficult to select the proper agent for a given infection. Nonspecific agents have been available for many years, and they are still effective in many situations. These agents include Whitfield's ointment, Castellani paint, gentian violet, potassium permanganate, undecylenic acid and selenium sulfide. Specific antifungal agents include, among others, the polyenes (nystatin, amphotericin B), the imidazoles (metronidazole, clotrimazole) and the allylamines (terbinafine, naftifine). Although the choice of an antifungal agent should be based on an accurate diagnosis, many clinicians believe that topical miconazole is a relatively effective agent for the treatment of most mycotic infections. Terbinafine and other newer drugs have primary fungicidal effects. Compared with older antifungal agents, these newer drugs can be used in lower concentrations and shorter therapeutic courses. Studies are needed to evaluate the clinical efficacies and cost advantages of both newer and traditional agents.

    Kenney, R A

    1986-04-01

    The Chinese Restaurant Syndrome arose from an anecdote of discomfort experienced after eating Chinese cuisine. Monosodium glutamate has been implicated as the causative agent. Work over the past 17 years has consistently failed to reveal any objective sign accompanying the transient sensations that some individuals experience after the experimental ingestion of monosodium glutamate and it is questionable whether the term 'Chinese Restaurant Syndrome' has any validity. When some common food materials are used in the same experimental setting, similar symptoms can be produced in a limited number of people. Double-blind testing of individuals who identify themselves as suffering the 'syndrome' has failed to confirm the role of monosodium glutamate as the provocative agent.

    To evaluate the clinical effect of Traditional Chinese Spinal Orthopedic Manipulation (TCSOM) in treating Irritable Bowel Syndrome (IBS) in comparison with Pinaverium Bromide Dicetel (PBD), and to assess a possible cause for IBS. 60 cases of IBS patients were randomly divided into two groups: TCSOM and PBD. All patients in the TCSOM group were treated with a 5-time spinal manipulations. The symptoms of pre-treatment and post-treatment were evaluated based on bowel symptom scale (BSS) scores. A symptom improvement rating (SIR) and patient subjective assessment (PSA) were implemented in order to evaluate the effects of the treatments, and to statistically compare the two groups. The symptoms of 23 patients of the TCSOM group disappeared soon after spinal manipulation and 6 cases were significantly improved. The BSS scores in the TCSOM group were significantly lower than those in the PBD group post-treatment. According to the SIR which was based on the BSS, the TCSOM research group included 14 cases with excellent results, 13 cases with good, and 3 cases with poor. Adverse side effects to the treatment were not reported. Based on the BSS, the PBD research group reported 7 cases with excellent results, 8 cases with good and 15 cases with poor. All cases were statistically analyzed, revealing a significant difference (Pinter-vertebral disks and/or vertebra in the thoracic or lumbar region seems to be a contributing factor in the symptoms of irritable bowel syndrome.

    2009-02-01

    Full Text Available This article examines transformations in the roles and treatment practices of traditional Palestinian women healers in Israel. Comparing narratives of women healers residing in Jewish-Arab mixed cities in central Israel with those of their counterparts in the Bedouin community of the Negev reveals that traditional healing has not disappeared as a result of modernization but rather has transformed. Urban women healers are abandoning treatment of physical problems in favor of addressing life hardships; they distance themselves from problems whose cause and treatment are considered natural and prefer those perceived as derived from supernatural causes and treated through supernatural, magical and religious means. Despite these transformations, traditional Palestinian women healers appear as agents of preservation and conservatism, a role that imbues them with a central position in their community. Hence, their place is currently secured and expected to remain so as processes of modernization and acculturation increase in intensity. URN: urn:nbn:de:0114-fqs0902119

    Tianjin, as the earliest city to open up, the exchange of Chinese and Western cultures also started earlier. Therefore, today's emergency medicine system with integrated features of Chinese and Western medicine is formed. Professor Wang Jinda, who works in Tianjin First Center Hospital, makes the theory of "treating bronchitis and treating diseases" and "three methods of three syndromes" for the treatment of severe diseases such as sepsis. The surgical aspect is the treatment of acute abdomen with the combination of Chinese and Western medicine which is proposed by Academician Wu Xianzhong who worked in Tianjin Nankai Hospital. In the aspect of acupuncture and moxibustion, Professor Guo Yi, who works in Tianjin University of Traditional Chinese Medicine, provides the twelve Jing points blood-letting therapy for cerebral diseases such as stroke. Professor Liu Xinqiao from the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine also conducts in-depth studies on brain protection after cardiopulmonary resuscitation (CPR). He proposes the importance of traditional Chinese medicine in addition to mild hypothermia and neuroprotective agents. The author summarized these achievements, in light of which looked forward to the future and proposed the concept of establishing a multi-specialist collaboration and an emergency center with obvious characteristics of integrated Chinese and Western medicine, which would pave the way for the development of integrated Chinese and Western medicine first aid.

    2012-02-01

    Lemierre\\'s syndrome is a rare disease that results in an oropharyngeal infection, which precipitates an internal jugular vein thrombosis and metastatic infection. Fusobacterium necrophorum is an anaerobic Gram-negative bacillus and has been identified as the causative agent. We describe the case of a young girl whose presentation and diagnosis were confounded by a history of valvular heart disease. Infection of heart valves can produce many of the signs and symptoms associated with Lemierre\\'s syndrome. We describe the diagnosis, investigation and optimal management of this rare disorder.

    Full Text Available Cotrimoxazole is a commonly used antimicrobial agent which is traditionally indicated in the management of pneumocystis infection of which HIV and immunosuppressed individuals are at high risk. Furthermore, it can be used on the long term for prophylactic indications. Hypoglycaemia following commencement of cotrimaoxazole is a rare adverse effect which was first described in 1988. We describe a case of hypoglycaemia shortly following initiation of cotrimoxazole indicated as long-term prophylaxis on a background of Churg-Strauss syndrome. The patient was symptomatic for hypoglycaemia despite simultaneous use of high-dose prednisolone; however, the hypoglycaemia did not require a hospital admission. We will explore the risk factors, monitoring requirements, and the mechanism by which co-trimoxazole induces hypoglycaemia.

    To investigate the effectiveness of traditional manual acupuncture combined with rehabilitation therapy versus rehabilitation therapy alone for shoulder hand syndrome after stroke. PubMed, EMBASE, the Cochrane Library, Chinese Biomedicine Database, China National Knowledge Infrastructure, VIP Information Database, Wan Fang Database and reference lists of the eligible studies were searched up to July 2017 for relevant studies. Randomized controlled trials that compared the combined effects of traditional manual acupuncture and rehabilitation therapy to rehabilitation therapy alone for shoulder hand syndrome after stroke were included. Two reviewers independently screened the searched records, extracted the data and assessed risk of bias of the included studies. The treatment effect sizes were pooled in a meta-analysis using RevMan 5.3 software. A total of 20 studies involving 1918 participants were included in this study. Compared to rehabilitation therapy alone, the combined therapy significantly reduced pain on the visual analogue scale and improved limb movement on the Fugl-Meyer Assessment scale and the performance of activities of daily living (ADL) on the Barthel Index scale or Modified Barthel Index scale. Of these, the visual analogue scale score changes were significantly higher (mean difference = 1.49, 95% confidence interval = 1.15-1.82, P < 0.00001) favoring the combined therapy after treatment, with severe heterogeneity ( I 2  = 71%, P = 0.0005). Current evidence suggests that traditional manual acupuncture integrated with rehabilitation therapy is more effective in alleviating pain, improving limb movement and ADL. However, considering the relatively low quality of available evidence, further rigorously designed and large-scale randomized controlled trials are needed to confirm the results.

    Full Text Available Nonparaneoplastic opsoclonus–myoclonus ataxia syndrome is a rare neuroinflammatory condition featured by opsoclonus, myoclonus, ataxia, and cognitive behavioral disturbance. The authors report an observation of enterovirus 71-associated opsoclonus–myoclonus ataxia syndrome evolving toward full recovery on intravenous intravenous immunoglobulin (IG treatment. Based on this case report, enterovirus 71 should be added to the list of infectious agents likely involved in opsoclonus–myoclonus ataxia syndrome, including the emerging subgroup of opsoclonus–myoclonus ataxia syndrome recovering without aggressive or prolonged immunosuppressive intervention. Further studies are mandatory to define the precise role, incidence, treatment, and outcome of enterovirus 71 and other infectious agents in benign forms of opsoclonus–myoclonus ataxia syndrome.

    Miller Fisher syndrome, a variant of Guillain-Barré syndrome, is an acute inflammatory demyelinating polyradiculoneuropathy that may occur weeks after a bacterial or viral infection. Campylobacter jejuni and Haemophilus influenzae are frequently reported etiological agents. We describe a boy with Miller Fisher syndrome following Epstein-002DBarr virus primary infectious mononucleosis. He presented with bilateral dysfunction of several cranial nerves and hyporeflexia of the limbs but without ataxia. Miller Fisher syndrome was confirmed by the presence of anti-GQ1b antibodies in a blood sample. Epstein-Barr virus was identified by polymerase chain reaction and serology. Epstein-Barr virus should be considered as a Miller Fisher syndrome's causative agent. The physiopathology of this condition may involve cross-reactive T-cells against Epstein-Barr virus antigens and gangliosides. Copyright © 2016 Elsevier Inc. All rights reserved.

    2017-04-01

    Metabolic syndrome is a disorder which encompasses obesity, high blood glucose, high cholesterol levels and high blood pressure. Moreover, metabolic syndrome is considered as the most important risk factor for cardiovascular disease (CVD). CVD is the leading cause of mortality in the world for both men and women. Several chemical drugs are available to treat metabolic risk factors, but because of the safety, efficacy, cultural acceptability and lesser side effects, nowadays herbal therapy has a critical role in the treatment of these CVD risk factors. Crocus sativus L. (saffron) is a perennial herb that belongs to the Iridaceae family. Saffron is an extensively used food additive for its colour and taste and has been widely used in traditional as well as modern medicine to treat several illnesses including cardiovascular diseases. Most of the unique properties of this plant are attributed to the presence of three major components, including crocin, safranal and crocetin. It has been proved that saffron has an important role in the management of metabolic syndrome because of its marvelous activities including anti-diabetic, anti-obesity, hypotensive and hypolipidaemic properties. In this review article, we discuss the beneficial properties of saffron and its active components to treat different components of metabolic syndrome and most relevant animal and human studies regarding the use of this plant in cardiovascular disease, with focus on the metabolic risk factors. This review also suggests that after randomised clinical trials, saffron may be implicated as a preventive or therapeutic agent against metabolic syndrome. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    2005-05-01

    Selective serotonin reuptake inhibitors (SSRI\\'s) are increasingly being used as the first line therapeutic agent for the depression. It is therefore not unusual to see a case of overdose with these agents. More commonly an adverse drug reaction may be seen among the older patients who are particularly vulnerable to the serotonin syndrome due to multiple co-morbidity and polypharmacy. The clinical picture of serotonin syndrome (SS) is non-specific and there is no confirmatory test. SS may go unrecognized because it is often mistaken for a viral illness, anxiety, neurological disorder or worsening psychiatric condition.

  9. Psoriatic arthritis: treatment strategies using biologic agents

    2012-06-01

    Full Text Available The traditional management of psoriatic arthritis (PsA includes NSAIDs, corticosteroids and DMARDs. Advancement in the knowledge of the immunopathogenesis of PsA has been associated with the development of biologic agents which have revolutionized the management of the disease. Among biologics drugs, there are the 4 currently availablee anti-TNFα blocking agents (etanercept, infliximab, adalimumab and golimumab which are more effective than traditional DMARDs on symptoms/signs of inflammation, quality of life, function, and in inhibiting the progression of the structural joint damage. Despite of the high cost, TNF inhibitors are costeffective on both the musculoskeletal and skin manifestations of psoriatic disease.

    Epigenetic changes resulting from aberrant methylation patterns are a recurrent observation in hematologic malignancies. Hypomethylating agents have a well-established role in the management of patients with high-risk myelodysplastic syndrome or acute myeloid leukemia. In addition to the direct effects of hypomethylating agents on cancer cells, there are several lines of evidence indicating a role for immune-mediated anti-tumor benefits from hypomethylating therapy. Areas covered: We reviewed the clinical and basic science literature for the effects of hypomethylating agents, including the most commonly utilized therapeutics azacitidine and decitabine, on immune cell subsets. We summarized the effects of hypomethylating agents on the frequency and function of natural killer cells, T cells, and dendritic cells. In particular, we highlight the effects of hypomethylating agents on expression of immune checkpoint inhibitors, leukemia-associated antigens, and endogenous retroviral elements. Expert commentary: In vitro and ex vivo studies indicate mixed effects on the function of natural killer, dendritic cells and T cells following treatment with hypomethylating agents. Clinical correlates of immune function have suggested that hypomethylating agents have immunomodulatory functions with the potential to synergize with immune checkpoint therapy for the treatment of hematologic malignancy, and has become an active area of clinical research.

    Traditional seed coating agents often contain toxic ingredients, which contaminate the environment and threaten human health. This paper expounds a method of preparing a novel environment-friendly seed coating agent for maize and researches its mechanism of action. The natural polysaccharide polymer, which is the main active ingredient of this environment-friendly seed coating agent, has the characteristics of innocuity and harmlessness, and it can replace the toxic ingredients used in traditional seed coating agents. This environment-friendly seed coating agent for maize was mainly made up of the natural polysaccharide polymer and other additives. The field trials results showed that the control efficacy of Helminthosporium maydis came to 93.72%, the anti-feeding rate of cutworms came to 81.29%, and the maize yield was increased by 17.75%. Besides, the LD 50 value (half the lethal dose in rats) of this seed coating agent was 10 times higher than that of the traditional seed coating agents. This seed coating agent could improve the activity of plant protective enzymes (peroxidase, catalase and superoxidase dismutase) and increase the chlorophyll content. This seed coating agent has four characteristics of disease prevention, desinsectization, increasing yield and safety. Results of mechanism analyses showed that this seed coating agent could enhance disease control effectiveness by improving plant protective enzymes activity and increase maize yield by improving chlorophyll content. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Full Text Available Among hantaviruses (HTNV, 22 are known as pathogenic for humans. HTNV can cause two clinical entities: hemorrhagic fever with renal syndrome (HFRS and hantavirus pulmonary syndrome or hantavirus cardiopulmonary syndrome (HCPS. In most countries of Eastern Europe as well as in Kosovo, HTNV infection is presented mainly as HFRS. Here, we report a 20-year-old man with HFRS and HCPS caused by Dobrava hantavirus strain, successfully treated in Intensive Care Unit of Infectious Diseases Clinic, University Clinical Center of Kosovo. In HFRS endemic areas, patients with acute respiratory distress syndrome need to be evaluated for Dobrava hantavirus strain as a possible causative agent.

    2011-01-01

    Tourette syndrome (TS) is a chronic neurodevelopmental disorder characterized by tics: repetitive, involuntary movements and vocalizations. These symptoms can have a significant impact on patients’ daily functioning across many domains. Tics tend to be most severe in child and adolescent sufferers, so their presence has the potential to impact a period of life that is both critical for learning and is often associated with the experience of greater social tension and self-consciousness than adulthood. Furthermore, control over tics that lead to physical impairment or self-injurious behaviour is of vital importance in maintaining health and quality of life. There are numerous complicating factors in the prescription of treatment for tics, due to both the side effects associated with alleviating agents and patient characteristics, such as age and comorbid conditions. This review summarizes literature pertaining to the efficacy and safety of both traditionally prescribed and more modern medications. We also discuss the merits of behavioural and surgical techniques and highlight newer emerging treatments. Although treatment response is to some extent variable, there are a number of agents that are clearly useful as first-line treatments for TS. Other interventions may be of most benefit to patients exhibiting refractory tics or more specific symptom profiles. PMID:21339906

  14. Reclassification of clinical sleep disorders using traditional models of syndromic, neuroanatomic, pathophysiological and etiological diagnosis.

    2014-09-01

    Existing classifications of central nervous system sleep disorders do not often provide tools to diagnose the majority of patients complaining of sleep-related symptoms, nor always guide effective treatment. I present a novel classification system that completely separates clinical syndromes from anatomical localization, pathophysiology, and etiology. The clinical syndrome I present can describe the majority of patients, but can be fractionated into individual subgroups for further study. By then separating the anatomy and physiology from the symptoms, an avenue of research becomes available to study the different possible structures that regulate sleep, that may be damaged and cause syndromes of sleep dysfunction. Some of these may produce symptoms that overlap with narcolepsy and some may be distinct. Because the clinical syndrome should be distinguished from anatomy or physiology, I have proposed the term narcoleptiform syndrome for the clinical syndrome. The model also clearly separates etiology from anatomy in a classical neurological manner. This allows etiology, localization and symptoms to be studied separately. It is likely that different etiologies may produce damage in areas that produce similar syndromes. For example, in this model, different causes of damage to the orexin nucleus would result in the same clinical syndrome. This reinforces the concept of studying anatomy, symptoms and etiology separately. By studying the relationship of syndromes or symptoms to anatomic localization and pathophysiology, it should be possible to test novel approaches to treatment based on different underlying structure or function. For example, patients with lesions in the ventrolateral preoptic nucleus or the thalamic intralaminar nuclei may both present with insomnia symptoms but need different treatment; or they might present with symptoms overlapping narcolepsy (a narcoleptiform syndrome) yet need different treatment. In some cases, a single treatment may cross over

    2018-01-01

    Full Text Available Polycystic ovary syndrome (PCOS is a common endocrine disorder in women of reproductive age. Its cause is unknown and it remains the most enigmatic of reproductive disorders. The extant written documents of Traditional Persian Medicine (TPM – with holistic approaches towards human health – contain remedies used for centuries. Before further experimental research on any of these treatments, it is appropriate to study current related scientific evidence on their possible pharmacological actions. This work aims to study PCOS and its treatments in TPM. To collect data from medieval medicinal texts, six of the most famous manuscripts of Persian medicine were studied. Medicinal treatments for a problem similar to PCOS were searched for in these books. The plants were listed and their authentications were confirmed in accordance with botanical books. PubMed and ScienceDirect databases were searched for related mechanisms of action or pharmacological activities of the medicinal plants reported. From numerous articles, the current work tried to cite the latest publications with regard to each reported plant and PCOS-related mechanisms of action. We studied herbal treatments recommended by ancient Persians to treat a condition called Habs-e-tams, which had the same symptoms of PCOS. It could be concluded that ancient physicians not only wanted to treat the irregular menstrual cycle—which is the most obvious symptom of PCOS—but also their treatment options were aimed at ameliorating the related underlying metabolic dysfunctions. The recommended herbs, which have the most scientific proof for their related actions, can be studied further in experimental analyses.

    2011-05-01

    With the increasing use of antiplatelet agents (APA), their management during the periendoscopic period has become a more common and more difficult problem. The increase in use is due to the availability of new drugs and the widespread use of drug-eluting coronary stents. Acute coronary syndromes can occur when APA therapy is withheld for noncardiovascular interventions. Guidelines about APA management during the periendoscopic period are traditionally based on assessments of the procedure-related risk of bleeding and the risk of thrombosis if APA are stopped. New data allow better assessment of these risks, of the necessary duration of APA discontinuation before endoscopy, of the use of alternative procedures (mostly for endoscopic retrograde cholangiopancreatography [ERCP]), and of endoscopic methods that can be used to prevent bleeding (following colonic polypectomy). This guideline makes graded, evidence-based, recommendations for the management of APA for all currently performed endoscopic procedures.

    Aoyama, Hideaki; Chakrabarti, Bikas; Chakraborti, Anirban; Ghosh, Asim

    2014-01-01

    The primary goal of this book is to present the research findings and conclusions of physicists, economists, mathematicians and financial engineers working in the field of "Econophysics" who have undertaken agent-based modelling, comparison with empirical studies and related investigations. Most standard economic models assume the existence of the representative agent, who is “perfectly rational” and applies the utility maximization principle when taking action. One reason for this is the desire to keep models mathematically tractable: no tools are available to economists for solving non-linear models of heterogeneous adaptive agents without explicit optimization. In contrast, multi-agent models, which originated from statistical physics considerations, allow us to go beyond the prototype theories of traditional economics involving the representative agent. This book is based on the Econophys-Kolkata VII Workshop, at which many such modelling efforts were presented. In the book, leading researchers in the...

  20. Increasing the effectiveness of hematopoiesis in myelodysplastic syndromes: erythropoiesis-stimulating agents and transforming growth factor-β superfamily inhibitors.

    Science.gov (United States)

    Mies, Anna; Platzbecker, Uwe

    2017-07-01

    Patients with lower-risk myelodysplastic syndromes (MDS) are mainly affected by chronic anemia and fatigue. Treatment strategies aim to improve anemia and quality of life, as well as iron overload due to red blood cell transfusion support. To promote proliferation and differentiation of erythropoiesis, erythropoiesis-stimulating agents (ESAs) such as erythropoietin (EPO) and mimetics are applied as first-line therapy in a large fraction of lower-risk MDS patients. In general, ESAs yield favorable responses in about half of the patients, although responses are often short-lived. In fact, many ESA-refractory patients harbor defects in late-stage erythropoiesis downstream of EPO action. Novel transforming growth factor (TGF)-β superfamily inhibitors sotatercept and luspatercept represent a promising approach to alleviate anemia by stimulating erythroid differentiation.

    Rastgoftar, Hossein

    2016-01-01

    This monograph presents new algorithms for formation control of multi-agent systems (MAS) based on principles of continuum mechanics. Beginning with an overview of traditional methods, the author then introduces an innovative new approach whereby agents of an MAS are considered as particles in a continuum evolving in ℝn whose desired configuration is required to satisfy an admissible deformation function. The necessary theory and its validation on a mobile-agent-based swarm test bed are considered for two primary tasks: homogeneous transformation of the MAS and deployment of a random distribution of agents on a desired configuration. The framework for this model is based on homogeneous transformations for the evolution of an MAS under no inter-agent communication, local inter-agent communication, and intelligent perception by agents. Different communication protocols for MAS evolution, the robustness of tracking of a desired motion by an MAS evolving in ℝn, and the effect of communication delays in an MAS...

    2012-01-01

    Full Text Available This study was designed to evaluate the in vitro antifungal activities of four traditional Chinese medicine (TCM extracts. The inhibitory effects of pseudolaric acid B, gentiopicrin, rhein, and alion were assessed using standard disk diffusion and broth microdilution assays. They were tested against six oral Candida species, Candida albicans, Candida glabrata, Candida tropicalis, Candida krusei, Candida dubliniensis, and Candida guilliermondii, including clinical isolates from HIV-negative, HIV-positive, and Sjögren's syndrome patients. It was found that pseudolaric acid B had the most potent antifungal effect and showed similar antifungal activity to all six Candida spp, and to isolates from HIV-negative, HIV-positive, and Sjögren's syndrome patients. The MIC values ranged from 16 to 128 μg/mL. More interestingly, a synergistic effect of pseudolaric acid B in combination with fluconazole was observed. We suggest that pseudolaric acid B might be a potential therapeutic fungicidal agent in treating oral candidiasis.

    2007-01-01

    Dry eye syndrome is a common chronic disease; agents and strategies for its effective management are still lacking. The syndrome tends to be accompanied by ocular surface inflammation; therefore, the use of anti-inflammatory agents might prove beneficial. The authors present up-to-date guidelines, strategies, and efficacy of dry eye syndrome management, including anti-inflammatory treatment. As no diagnostic tests are now available to assess ocular surface inflammation severity, the right timing to launch an anti-inflammatory agent is difficult to determine. Patients with mild intermittent bouts of symptoms which can be alleviated with ophthalmic lubricants do not typically require anti-inflammatory therapy. The latter should be considered in those who do not respond to lubricating drops, obtain poor results on clinical tests, and show symptoms of ocular surface irritation (eg. conjunctivae redness). Anti-inflammatory treatment of dry eye syndrome may include short-term corticosteroids, cyclosporine A emulsion, oral tetracycline therapy, oral omega-3 fatty acid supplements, and autologous serum eye drops. Anti-inflammatory treatment should be safe and effective; potential benefits should be evaluated for each individual patient. The authors have reviewed the advantages of anti-inflammatory treatment in dry eye syndrome, presented in literature.

  5. Double agents and secret agents: the emerging fields of exogenous chemical exchange saturation transfer and T2-exchange magnetic resonance imaging contrast agents for molecular imaging.

    Science.gov (United States)

    Daryaei, Iman; Pagel, Mark D

    2015-01-01

    Two relatively new types of exogenous magnetic resonance imaging contrast agents may provide greater impact for molecular imaging by providing greater specificity for detecting molecular imaging biomarkers. Exogenous chemical exchange saturation transfer (CEST) agents rely on the selective saturation of the magnetization of a proton on an agent, followed by chemical exchange of a proton from the agent to water. The selective detection of a biomarker-responsive CEST signal and an unresponsive CEST signal, followed by the ratiometric comparison of these signals, can improve biomarker specificity. We refer to this improvement as a "double-agent" approach to molecular imaging. Exogenous T 2 -exchange agents also rely on chemical exchange of protons between the agent and water, especially with an intermediate rate that lies between the slow exchange rates of CEST agents and the fast exchange rates of traditional T 1 and T 2 agents. Because of this intermediate exchange rate, these agents have been relatively unknown and have acted as "secret agents" in the contrast agent research field. This review exposes these secret agents and describes the merits of double agents through examples of exogenous agents that detect enzyme activity, nucleic acids and gene expression, metabolites, ions, redox state, temperature, and pH. Future directions are also provided for improving both types of contrast agents for improved molecular imaging and clinical translation. Therefore, this review provides an overview of two new types of exogenous contrast agents that are becoming useful tools within the armamentarium of molecular imaging.

    Pseudogymnoascus destructans is the causative agent of white-nose syndrome, a disease that has caused the deaths of millions of bats in North America. This psychrophilic fungus proliferates at low temperatures and targets hibernating bats, resulting in their premature arousal from stupor with catastrophic consequences. Despite the impact of white-nose syndrome, little is known about the fungus itself or how it infects its mammalian host. P. destructans is not amenable to genetic manipulation, and therefore understanding the proteins involved in infection requires alternative approaches. Here, we identify hydrolytic enzymes secreted by P. destructans, and use a novel and unbiased substrate profiling technique to define active peptidases. These experiments revealed that endopeptidases are the major proteolytic activities secreted by P. destructans, and that collagen, the major structural protein in mammals, is actively degraded by the secretome. A serine endopeptidase, hereby-named Destructin-1, was subsequently identified, and a recombinant form overexpressed and purified. Biochemical analysis of Destructin-1 showed that it mediated collagen degradation, and a potent inhibitor of peptidase activity was identified. Treatment of P. destructans-conditioned media with this antagonist blocked collagen degradation and facilitated the detection of additional secreted proteolytic activities, including aminopeptidases and carboxypeptidases. These results provide molecular insights into the secretome of P. destructans, and identify serine endopeptidases that have the clear potential to facilitate tissue invasion and pathogenesis in the mammalian host.

    Full Text Available The phytochemical constituents which comprise many edible berry fruits have increasingly been linked to modulation of biomarkers associated with conditions of diabetes, overweight/obesity, and cardiovascular disease (CVD, all components of metabolic syndrome. While many wild berries have long been valued in traditional medicine as health protective, it is only recently that the ability of berry bioactives to affect particular clinical targets has been demonstrated. In addition to the widely recognized antioxidant power of berry extracts, both commercial berry varieties and wild species have been linked to hypoglycemic activity, inhibition of adipogenesis, amelioration of CVD risk factors, anti-inflammatory capacity, and ability to induce satiety/counteract overweight. In some cases, proanthocyanidin constituents or anthocyanin pigments have been shown to be the active agents, but in many other cases, interactions between co-occuring phytochemical constituents potentiate bioactivity of berry extracts.

    A Jaundice Syndrome occurs sporadically among sea-pen-farmed Chinook Salmon in British Columbia, the westernmost province of Canada. Affected salmon are easily identified by a distinctive yellow discolouration of the abdominal and periorbital regions. Through traditional diagnostics, no bacterial or viral agents were cultured from tissues of jaundiced Chinook Salmon; however, piscine reovirus (PRV) was identified via RT-rPCR in all 10 affected fish sampled. By histopathology, Jaundice Syndrome is an acute to peracute systemic disease, and the time from first clinical signs to death is likely jaundiced Chinook Salmon, developed no gross or microscopic evidence of jaundice despite persistence of PRV for the 5-month holding period. The results from this study demonstrate that the Jaundice Syndrome was not transmissible by injection of material from infected fish and that PRV was not the sole aetiological factor for the condition. Additionally, these findings showed the Pacific coast strain of PRV, while transmissible, was of low pathogenicity for Atlantic Salmon, Chinook Salmon and Sockeye Salmon.

  9. Serotonin Syndrome in the Setting of Lamotrigine, Aripiprazole, and Cocaine Use

    2015-01-01

    Full Text Available Serotonin syndrome is a potentially life-threatening condition associated with increased serotonergic activity in the central nervous system. It is classically associated with the simultaneous administration of two serotonergic agents, but it can occur after initiation of a single serotonergic drug or increasing the dose of a serotonergic drug in individuals who are particularly sensitive to serotonin. We describe a case of serotonin syndrome that occurred after ingestion of higher than prescribed doses of lamotrigine and aripiprazole, in addition to cocaine abuse. The diagnosis was established based on Hunter toxicity criteria and severity was classified as mild. The features of this syndrome resolved shortly after discontinuation of the offending agents. Serotonin syndrome is characterized by mental status changes, autonomic hyperactivity, and neuromuscular abnormalities along a spectrum ranging from mild to severe. Serotonin syndrome in our patient was most likely caused by the pharmacokinetic and pharmacodynamic interactions between lamotrigine, aripiprazole, and cocaine leading to increased CNS serotonergic activity.

    Both metformin and thiazolidinedione derivatives(TZDs) improve insulin resistance, a major pathogenesis of type 2 diabetes, and decrease blood glucose levels without stimulating insulin secretion. Metformin inhibits glucose output from the liver, while TZDs increase glucose utilization in the peripheral tissues. In addition, there has been indicated that these agents ameliorate metabolic syndrome beyond glucose-level lowering. Molecular targets of these agents have recently been revealed; AMP-activated protein kinase (AMPK) for metformin and adiponectin, while PPAR gamma for TZDs which induce gene expression of adipocyte glycerol kinase and adiponectin. Insulin-sensitizing agents are clinically useful for obese diabetic patients with insulin resistance. However, periodical examinations are necessary to avoid serious adverse effects such as lactic acidosis, although rare, by metformin and liver injury by TZDs.

  12. Optimal Wonderful Life Utility Functions in Multi-Agent Systems

    Wolpert, David H.; Tumer, Kagan; Swanson, Keith (Technical Monitor)

    2000-01-01

    The mathematics of Collective Intelligence (COINs) is concerned with the design of multi-agent systems so as to optimize an overall global utility function when those systems lack centralized communication and control. Typically in COINs each agent runs a distinct Reinforcement Learning (RL) algorithm, so that much of the design problem reduces to how best to initialize/update each agent's private utility function, as far as the ensuing value of the global utility is concerned. Traditional team game solutions to this problem assign to each agent the global utility as its private utility function. In previous work we used the COIN framework to derive the alternative Wonderful Life Utility (WLU), and experimentally established that having the agents use it induces global utility performance up to orders of magnitude superior to that induced by use of the team game utility. The WLU has a free parameter (the clamping parameter) which we simply set to zero in that previous work. Here we derive the optimal value of the clamping parameter, and demonstrate experimentally that using that optimal value can result in significantly improved performance over that of clamping to zero, over and above the improvement beyond traditional approaches.

    Substantial progress has been made in China in using traditional Chinese medicine (TCM) to treat acquired immune deficiency syndrome (AIDS). Our objective was to review the latest developments in TCM treatment of AIDS in China between 2004 and 2014. We reviewed the content of original articles investigating the efficacy and safety of TCM for treating AIDS published in Chinese and English language journals. Relevant references from 2004 to 2014 were found using PubMed and the China National Knowledge Infrastructure Database. We found that TCM has been widely used for treating AIDS and its complications in China. The number of TCM studies has increased, which indicates efficacy and safety. Measures of efficacy in the reviewed articles included the alleviation of human immunodeficiency virus (HIV)-related signs and symptoms, improvements in quality of life, improvements in long-term survival, counteraction of the adverse side effects of antiviral drugs, promotion of immune reconstitution, and improvement of laboratory results. In sum, the literature indicates that TCM is safe. TCM plays an important role in the treatment of AIDS. Some studies have attempted to measure the efficacy and safety of TCM for treating AIDS, but more evidence is needed. Therefore, more research on this topic is required in the future.

  14. Clustering recommendations to compute agent reputation

    2005-03-01

    Traditional centralized approaches to security are difficult to apply to multi-agent systems which are used nowadays in e-commerce applications. Developing a notion of trust that is based on the reputation of an agent can provide a softer notion of security that is sufficient for many multi-agent applications. Our paper proposes a mechanism for computing reputation of the trustee agent for use by the trustier agent. The trustier agent computes the reputation based on its own experience as well as the experience the peer agents have with the trustee agents. The trustier agents intentionally interact with the peer agents to get their experience information in the form of recommendations. We have also considered the case of unintentional encounters between the referee agents and the trustee agent, which can be directly between them or indirectly through a set of interacting agents. The clustering is done to filter off the noise in the recommendations in the form of outliers. The trustier agent clusters the recommendations received from referee agents on the basis of the distances between recommendations using the hierarchical agglomerative method. The dendogram hence obtained is cut at the required similarity level which restricts the maximum distance between any two recommendations within a cluster. The cluster with maximum number of elements denotes the views of the majority of recommenders. The center of this cluster represents the reputation of the trustee agent which can be computed using c-means algorithm.

  16. A distributed agent architecture for real-time knowledge-based systems: Real-time expert systems project, phase 1

    Science.gov (United States)

    Lee, S. Daniel

    1990-01-01

    We propose a distributed agent architecture (DAA) that can support a variety of paradigms based on both traditional real-time computing and artificial intelligence. DAA consists of distributed agents that are classified into two categories: reactive and cognitive. Reactive agents can be implemented directly in Ada to meet hard real-time requirements and be deployed on on-board embedded processors. A traditional real-time computing methodology under consideration is the rate monotonic theory that can guarantee schedulability based on analytical methods. AI techniques under consideration for reactive agents are approximate or anytime reasoning that can be implemented using Bayesian belief networks as in Guardian. Cognitive agents are traditional expert systems that can be implemented in ART-Ada to meet soft real-time requirements. During the initial design of cognitive agents, it is critical to consider the migration path that would allow initial deployment on ground-based workstations with eventual deployment on on-board processors. ART-Ada technology enables this migration while Lisp-based technologies make it difficult if not impossible. In addition to reactive and cognitive agents, a meta-level agent would be needed to coordinate multiple agents and to provide meta-level control.

    Conservative therapies for complex regional pain syndrome (CRPS) have traditionally focused on exercise and desensitization techniques targeted at the involved extremity. The primary purpose of this case series is to report on the potential benefit of utilizing manual therapy to the lumbar spine in conjunction with traditional conservative care when treating patients with lower extremity CRPS. Two patients with the diagnosis of lower extremity CRPS were treated with manual therapy to the lumbar spine in conjunction with education, exercise, desensitization, and soft tissue techniques for the extremity. Patient 1 received 13 sessions over 6 weeks resulting in a 34-point improvement in oswestry disability index (ODI) and 35-point improvement in lower extremity functional scale (LEFS). Patient 2 received 21 sessions over 12 weeks resulting in a 28-point improvement in ODI and a 41-point improvement in LEFS. Both patients exhibited reductions in pain and clinically meaningful improvements in function. Manual therapies when applied to the lumbar spine in these patients as part of a comprehensive treatment plan resulted in improved spinal mobility, decreased pain, and reduction is distal referred symptoms. Although one cannot infer a cause and effect relationship from a case series, this report identifies meaningful clinical outcomes potentially associated with manual physical therapy to the lumbar spine for two patients with complex regional pain syndrome type 1.

    To investigate if patients with Primary Antiphospholipid Syndrome (PAPS) with venous and/or arterial thrombosis without traditional coronary artery disease (CAD) risk factors develop early atherosclerotic vascular damage. 27 female patients with PAPS (Sidney criteria) and 27 age, body mass index (BMI), and sex matched controls were consecutively selected. Exclusion criteria were: black race, age ≥55 years, traditional cardiovascular risk factors, other thrombophilias or connective tissue diseases, corticosteroids use and pregnancy. All subjects underwent Pulse Wave Velocity (PWV) and Echo-Tracking (ET), both in carotidal bed, to analyse vascular functional properties. Age (p = 0.92) and BMI (p = 0.91) were comparable in both groups. PAPS patients and controls had similar PWV (9.07 ± 1.08 m/s vs 9.42 ± 1.47 m/s, p = 0.34) as well as echo tracking parameters such as intima-media thickness (683 ± 171 µm vs 636 ± 140 µm, p = 0.52), carotideal diameter (p = 0.26), distensibility (p = 0.92), compliance coefficients (p = 0.36) and elastic modulus (p = 0.78). Patients with exclusively venous thrombosis showed lower PWV than patients with arterial thrombosis (8.55 ± 0.70 m/s vs 9.56 ± 0.94 m/s, p = 0.01), but no difference regarding intima-media thickness (683 ± 171 µm vs 636 ± 140 µm, p = 0.52) was observed. Patients with PAPS do not seem to be at higher risk of developing premature atherosclerosis. Patients who suffered exclusively venous thrombosis seem to be at lower risk than those with exclusively arterial events. Other studies need to confirm our findings. © The Author(s) 2015.

    Idiopathic nephrotic syndrome is the most common chronic glomerular disease in children. At least 20 % of children with this syndrome show frequent relapses and/or steroid dependence during or after immunosuppressive therapies, a condition defined as complicated frequently relapsing/steroid-dependent nephrotic syndrome (FRNS/SDNS). Approximately 1-3 % of children with idiopathic nephrotic syndrome are resistant to steroids and all immunosuppressive agents, a condition defined as refractory steroid-resistant nephrotic syndrome (SRNS); these SRNS children have a high risk of end-stage renal failure. Rituximab, a chimeric anti-CD20 monoclonal antibody, has been shown to be effective for patients with complicated FRNS/SDNS and refractory SRNS. This review describes the recent results of rituximab treatment applied to pediatric nephrotic syndrome, as well as those of our recent study, a multicenter, double-blind, randomized, placebo-controlled trial of rituximab for childhood-onset complicated FRNS/SDNS (RCRNS01). The overall efficacy and safety of rituximab for this disease are discussed.

    Pharmacologically active constituents from traditional medicinal plants have received great attention as sources of novel agents, pharmaceutical intermediates, and chemical entities for synthetic or semisynthetic drugs due to their potent pharmacological activities, low toxicity, and economic viability. Numerous components have been isolated from traditional medicinal plants, including alkaloids, flavonoids, and terpenoids, and clinical and experimental studies suggested that these components have useful pharmacological properties such as antiinfectious, antioxidative, and antiinflammatory effects. In this review, modern ethnobotanical approaches to explore folk medicinal plants as candidates for drug discovery with the greatest possibility of success are discussed. Determining the bioactive mechanisms and tracing structure-activity relationships will promote the discovery of new drugs and pharmacological agents.

    Yang, Juno; Lee, Beom-Joon; Lee, Jun-Hwan

    The objective of our study is to present two cases showing the effects of traditional Korean herbal medicines based on traditional Korean medicine (TKM) for the treatment of immune thrombocytopenic purpura (ITP). One patient showed no response to treatment with steroids and an immunosuppressive agent. Moreover, liver toxicity and side effects of steroids were evident. However, after he ceased conventional treatment and started to take an herbal medicine, his liver function normalized and the steroid side effects resolved. Ultimately, he achieved complete remission. Another patient with ITP had sustained remission after steroid therapy in childhood, but extensive uterine bleeding and thrombocytopenia recurred when she was 16 years old. She was managed with steroids again for 2 years, but severe side effects occurred, and eventually she ceased taking steroids. She refused a splenectomy, and was then treated with a herbal medicine for 7 months, ultimately leading to sustained remission again. Many patients with resistance to first-line treatments tend to be reluctant to undergo a splenectomy, considered a standard second-line treatment. In conclusion, herbal medicines, based on TKM, may offer alternative treatments for persistent or chronic ITP that is resistant to existing first-line treatments. Copyright © 2017 The Authors.

    Full Text Available Excellent technologies have been developed to identify the specific microbial agents of chlamydia, gonorrhea, syphilis, herpes, chancroid, trichomoniasis, human papillomavirus and HIV infection. However, it is also crucial to recognize syndromes that may be caused by one or more sexually transmitted pathogens. When laboratory services are lacking or are inadequate to provide timely results to enable appropriate treatment, some patients must be managed and treated syndromically. Most Canadian laboratories should be able to provide diagnostic services to determine the etiology of syndromes such as cervicitis, urethritis, pelvic inflammatory disease, prostatitis, genital ulcers, sexually transmitted infection (STI-related enteric infections, epididymitis, hepatitis, ophthalmia neonatorum, vulvovaginitis and vaginosis.

  7. Cardiovascular Risk Factors in the Antiphospholipid Syndrome

    Felipe Freire da Silva

    2014-01-01

    Full Text Available A major cause of morbidity and mortality in the context of the antiphospholipid syndrome (APS is the occurrence of thrombotic events. Besides the pathogenic roles of antiphospholipid antibodies (aPL, other risk factors and medical conditions, which are conditions for traditional risk of an individual without the APS, can coexist in this patient, raising their risk of developing thrombosis. Therefore, the clinical and laboratory investigation of comorbidities known to increase cardiovascular risk in patients with antiphospholipid antibody syndrome is crucial for the adoption of a more complete and effective treatment. Experimental models and clinical studies show evidence of association between APS and premature formation of atherosclerotic plaques. Atherosclerosis has major traditional risk factors: hypertension, diabetes mellitus, obesity, dyslipidemia, smoking, and sedentary lifestyle that may be implicated in vascular involvement in patients with APS. The influence of nontraditional risk factors as hyperhomocysteinemia, increased lipoprotein a, and anti-oxLDL in the development of thromboembolic events in APS patients has been studied in scientific literature. Metabolic syndrome with all its components also has been recently studied in antiphospholipid syndrome and is associated with arterial events.

    2013-01-01

    Polycystic ovary syndrome (PCOS) is a heterogeneous syndrome of reproductive and metabolic derangements. The combination of anovulation and hyperandrogenism signifies the classic form of PCOS which displays the adverse metabolic phenotype of the syndrome. This phenotype includes visceral obesity and insulin resistance as well as a constellation of other traditional cardiovascular risk factors, mainly low grade inflammation, disturbances of glucose metabolism and dyslipidemia. The resultant increased risk for cardiovascular disease may affect not only obese but also lean women with classic PCOS. The mechanisms underlying the increased cardiovascular risk in the context of PCOS may include not only metabolic aberrations, but also hormonal factors, in particular hyperandrogenemia. However, the consequences in terms of CV morbidity remain questionable due to the difficulties in conducting long-term, prospective studies aimed at identifying potential late-arriving clinical outcomes.

    Joyce, Dan W.; Lewis, Paul H.; Tansley, Robert H.; Dobie, Mark R.; Hall, Wendy

    1999-12-01

    The purpose of this paper is two-fold. We begin by exploring the emerging trend to view multimedia information in terms of low-level and high-level components; the former being feature-based and the latter the 'semantics' intrinsic to what is portrayed by the media object. Traditionally, this has been viewed by employing analogies with generative linguistics. Recently, a new perceptive based on the semiotic tradition has been alluded to in several papers. We believe this to be a more appropriate approach. From this, we propose an approach for tackling this problem which uses an associative data structure expressing authored information together with intelligent agents acting autonomously over this structure. We then show how neural networks can be used to implement such agents. The agents act as 'vehicles' for bridging the gap between multimedia semantics and concrete expressions of high-level knowledge, but we suggest that traditional neural network techniques for classification are not architecturally adequate.

    To respond to the human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) epidemic in China, the integration of antiretroviral therapy (ART) and traditional Chinese medicine (TCM) has important implications in health outcomes, especially in China where the use of TCM is widespread. The National Free TCM Pilot Program for HIV Infected People began in 5 provinces (Henan, Hebei, Anhui, Hubei, and Guangdong) in 2004, and quickly scaled up to 19 provinces, autonomous regions, and municipalities in China including some places with high prevalence, 26,276 adults have been treated thus far. Usually, people with HIV infection seek TCM for four main reasons: to enhance immune function, to treat symptoms, to improve quality of life, and to reduce side effects related to medications. Evidences from randomized controlled clinical trials suggested some beneficial effects of use of traditional Chinese herbal medicine for HIV infections and AIDS. More proofs from large, well-designed, rigorous trials is needed to give firm support. Challenges include interaction between herbs and antiretroviral drugs, stigma and discrimination. The Free TCM Program has made considerable progress in providing the necessary alternative care and treatment for HIV-infected people in China, and has strong government support for continued improvement and expansion, establishing and improving a work mechanism integrating Chinese and Western medicines.

    2011-01-01

    The Jerusalem syndrome is an acute psychotic state observed in tourists and pilgrims who visit Jerusalem. The main symptom of this disorder is identification with a character from the Bible and exhibiting behaviours which seems to be typical for this character. The article presents an overview of cultural and demographic factors associated with the appearance of the Jerusalem syndrome. Three main categories of the syndrome were identified with special focus on the category unconjoined to previous psychopathology which can be described as the 'pure' form of the Jerusalem syndrome. The main diagnostic criteria for the 'pure' type and the sequence of seven clinical stages of the Jerusalem syndrome were described. The article contains a review of the hypothesis about the causes of Jerusalem syndrome with special attention given to the role of places of particular meaning for religious tradition.

  14. Metabolic syndrome induced by anticancer treatment in childhood cancer survivors.

    2017-06-01

    The number of childhood cancer survivors is increasing as survival rates improve. However, complications after treatment have not received much attention, particularly metabolic syndrome. Metabolic syndrome comprises central obesity, dyslipidemia, hypertension, and insulin resistance, and cancer survivors have higher risks of cardiovascular events compared with the general population. The mechanism by which cancer treatment induces metabolic syndrome is unclear. However, its pathophysiology can be categorized based on the cancer treatment type administered. Brain surgery or radiotherapy may induce metabolic syndrome by damaging the hypothalamic-pituitary axis, which may induce pituitary hormone deficiencies. Local therapy administered to particular endocrine organs directly damages the organs and causes hormone deficiencies, which induce obesity and dyslipidemia leading to metabolic syndrome. Chemotherapeutic agents interfere with cell generation and growth, damage the vascular endothelial cells, and increase the cardiovascular risk. Moreover, chemotherapeutic agents induce oxidative stress, which also induces metabolic syndrome. Physical inactivity caused by cancer treatment or the cancer itself, dietary restrictions, and the frequent use of antibiotics may also be risk factors for metabolic syndrome. Since childhood cancer survivors with metabolic syndrome have higher risks of cardiovascular events at an earlier age, early interventions should be considered. The optimal timing of interventions and drug use has not been established, but lifestyle modifications and exercise interventions that begin during cancer treatment might be beneficial and tailored education and interventions that account for individual patients' circumstances are needed. This review evaluates the recent literature that describes metabolic syndrome in cancer survivors, with a focus on its pathophysiology.

From 1st January 2003 to 31st May 2009 in the PED, all patients admitted for tourniquet syndrome were included in the study. The data collected were day and time of admission, age, sex, length of stay, medical coverage, type and location of the constrictive agent, therapeutic management, progression, and complications. PED social workers in relation with child protective services (CPS) recovered information on the family's social situation. During the study period, 57 children were registered. The mean number of admissions per year was 8 (range: 2-15). The mean age was 5.5+/-4 months. The toe was the most frequent location (95%). The penis was injured in 2 cases and labia majora in 1 case. The constrictive agent was often a hair (95%). One case of abuse was detected. The analysis of family social situations showed that 53% had no or incomplete medical coverage, 67% were already followed by CPS with extreme poverty or lived in dilapidated housing. Insufficient hygiene or neglect was found in 67% of the families with incomplete or no social coverage. The analysis of 2003-2007 period for later admissions identified that 15 accidents in the home occurred in 12 children. Among these families, 58% were already known by CPS for neglect behavior. Although most tourniquet syndromes seem accidental, this entity is often associated with a lack of hygiene. Several and distant locations (e.g., toes and genitals), multiple and/or separated knots, constrictive agents inconsistent with a safe environment for the child, and penile location in an infant require meticulous investigation because of a higher incidence of child neglect.

    Full Text Available The aim of this study is to explore the correlation of laboratory data, hormone peptides, and quality of life with different traditional Chinese medicine (TCM syndrome groups in type 2 diabetes patients. Of 513 registered patients, 179 subjects aged between 20 and 65 years and having type 2 diabetes mellitus (T2DM for more than 1 year were enrolled in the study. All the participants were asked to fill out a questionnaire on diabetic TCM syndrome groups, which was designed by professional TCM doctors, and two questionnaires on the quality of life (QOL, WHOQOL-BREF Taiwan version and Medical Outcomes Study (MOS Short Form-12 (SF-12. The biochemical characteristics and hormone peptide levels were collected at the same time. The patients in any one of the six TCM syndrome groups had the trend to have worse QOL. Especially, patients with qi deficiency had worse life quality on every aspect compared to those without qi deficiency and were fatter than others. We also found that the subjects who had qi deficiency, qi stagnation, and yin deficiency at the same time had worsened condition. We consider that patients with qi deficiency may also be at a higher risk of developing other complications. They need more advanced health care than others. This self-reported questionnaire will be a reference for health care workers screening those T2DM patients who have a higher possibility of developing other complications. Especially in remote areas, where there is a lack of medical resources, an easy-to-use tool such as the one in the present study for detecting and evaluating disease conditions is needed.

    Polycystic ovary syndrome is the most common endocrine disorder among women of reproductive age. Although traditionally viewed as a reproductive disorder, there is increasing appreciation that it is associated with significantly increased risk of cardiometabolic disorders. Women with polycystic ovary syndrome may present to clinicians via a variety of different routes and symptoms. Although the impact on reproduction predominates during the reproductive years, the increased cardiometabolic problems are likely to become more important at later stages of the life course. Women with polycystic ovary syndrome have an approximately 2- to 5-fold increased risk of dysglycaemia or type 2 diabetes, and hence regular screening with oral glucose tolerance test is warranted. Although the diagnostic criteria for polycystic ovary syndrome are still evolving and are undergoing revision, the diagnosis is increasingly focused on the presence of hyperandrogenism, with the significance of polycystic ovarian morphology in the absence of associated hyperandrogenism or anovulation remaining uncertain. The management of women with polycystic ovary syndrome should focus on the specific needs of the individual, and may change according to different stages of the life course. In view of the clinical manifestations of the condition, there is recent debate about whether the current name is misleading, and whether the condition should be renamed as metabolic reproductive syndrome.

    White-nose syndrome (WNS), an emerging disease of hibernating bats, has rapidly spread across eastern North America killing millions of bats. Pseudogymnoascus destructans (Pd), the sole etiologic agent of WNS, is widespread and persistent in bat hibernacula. Control of Pd in the affected sites is urgently needed to break the transmission cycle while minimizing any adverse impact on the native organisms. We isolated a novel strain of Trichoderma polysporum (Tp) from one of the caves at the epicenter of WNS zoonotic. Detailed experimental studies revealed: (1) Tp WPM 39143 was highly adapted to grow at temperatures simulating the cave environment (6°C-15°C), (2) Tp WPM 39143 restricted Pd colony growth in dual culture challenges, (3) Tp WPM 39143 caused four logs reduction of Pd colony forming units and genome copies in autoclaved soil samples from one of the WNS affected caves, (4) Tp WPM 39143 extract showed specific fungicidal activity against Pd in disk diffusion assay, but not against closely related fungus P. pannorum (Pp), (5) Tp WPM 39143 extract retained inhibitory activity after exposure to high temperatures, light and proteinase K, and (6) Inhibitory metabolites in Tp WPM 39143 extract comprised of water-soluble, high polarity compounds. These results suggest that Tp WPM 39143 is a promising candidate for further evaluation as a biocontrol agent of Pd in WNS affected sites.

    Cushing's syndrome (CS) is a rare but severe clinical condition represented by an excessive endogenous cortisol secretion and hence excess circulating free cortisol, characterized by loss of the normal feedback regulation and circadian rhythm of the hypothalamic-pituitary axis due to inappropriate secretion of ACTH from a pituitary tumor (Cushing's disease, CD) or an ectopic source (ectopic ACTH secretion, EAS). The remaining causes (20%) are ACTH independent. As soon as the diagnosis is established, the therapeutic goal is the removal of the tumor. Whenever surgery is not curative, management of patients with CS requires a major effort to control hypercortisolemia and associated symptoms. A multidisciplinary approach that includes endocrinologists, neurosurgeons, oncologists, and radiotherapists should be adopted. This paper will focus on traditional and novel medical therapy for aggressive ACTH-dependent CS. Several drugs are able to reduce cortisol levels. Their mechanism of action involves blocking adrenal steroidogenesis (ketoconazole, metyrapone, aminoglutethimide, mitotane, etomidate) or inhibiting the peripheral action of cortisol through blocking its receptors (mifepristone “RU-486”). Other drugs include centrally acting agents (dopamine agonists, somatostatin receptor agonists, retinoic acid, peroxisome proliferator-activated receptor γ “PPAR-γ” ligands) and novel chemotherapeutic agents (temozolomide and tyrosine kinase inhibitors) which have a significant activity against aggressive pituitary or ectopic tumors.

    We herein report the case of a 38-year-old Japanese woman with antithyroid arthritis syndrome who experienced severe migratory polyarthritis after the initiation of thiamazole therapy. The patient's symptoms promptly disappeared without any sequelae after the withdrawal of the drug. Antithyroid arthritis syndrome is poorly characterized, and the findings from our literature review indicate that this syndrome exhibits serological features that are distinct from those of antithyroid agent-induced vasculitis syndrome. The absence of autoantibodies, especially anti-neutrophil cytoplasmic antibodies, may help characterize and diagnose antithyroid arthritis syndrome. Furthermore, physicians' awareness of this syndrome is essential for its diagnosis in clinical practice. PMID:27980264

    Despite descriptions of runting-stunting syndrome (RSS) in broiler chickens dating back over 40 years, the aetiology has not yet been described. A novel chicken astrovirus (CkAstV) was isolated in an LMH liver cell line from the intestines of chickens affected with RSS. Clinical RSS is characterized by retarded growth and cystic crypt lesions in the small intestine. In 1-day-old broiler chickens infected with the CkAstV isolate, virus was only detected in the intestinal epithelial cells during the first few days after infection. Notably, the preferred host cells are the crypt epithelial cells following initial replication in the villous epithelial cells, thus implying viral preference for immature intestinal cells. Nevertheless, the CkAstV isolate did not induce remarkable pathological changes, despite the presence of the virus in situ. Serial chicken-to-chicken passages of the virus induced increased virulence, as displayed by decreased weight gain and the presence of cystic lesions in the small intestine reproducing clinical RSS in chickens. The analysis of the full-length genome sequences from the isolated CkAstV and the CkAstV from the bird-to-bird passages showed >99 % similarity. The data obtained in this study suggest that the CkAstV isolate is capable of inducing RSS following serial bird-to-bird passages in broilers and is as an aetiological agent of the disease.

  4. Lynch Syndrome: An Updated Review

    Full Text Available Lynch syndrome is one of the most common cancer susceptibility syndromes. Individuals with Lynch syndrome have a 50%–70% lifetime risk of colorectal cancer, 40%–60% risk of endometrial cancer, and increased risks of several other malignancies. It is caused by germline mutations in the DNA mismatch repair genes MLH1, MSH2, MSH6 or PMS2. In a subset of patients, Lynch syndrome is caused by 3' end deletions of the EPCAM gene, which can lead to epigenetic silencing of the closely linked MSH2. Relying solely on age and family history based criteria inaccurately identifies eligibility for Lynch syndrome screening or testing in 25%–70% of cases. There has been a steady increase in Lynch syndrome tumor screening programs since 2000 and institutions are rapidly adopting a universal screening approach to identify the patients that would benefit from genetic counseling and germline testing. These include microsatellite instability testing and/or immunohistochemical testing to identify tumor mismatch repair deficiencies. However, universal screening is not standard across institutions. Furthermore, variation exists regarding the optimum method for tracking and disclosing results. In this review, we summarize traditional screening criteria for Lynch syndrome, and discuss universal screening methods. International guidelines are necessary to standardize Lynch syndrome high-risk clinics.

    With the completion of the human genome project, people have gradually recognized that the functions of the biological system are fulfilled through network-type interaction between genes, proteins and small molecules, while complex diseases are caused by the imbalance of biological processes due to a number of gene expression disorders. These have contributed to the rise of the concept of the "multi-target" drug discovery. Treatment and diagnosis of traditional Chinese medicine are based on holism and syndrome differentiation. At the molecular level, traditional Chinese medicine is characterized by multi-component and multi-target prescriptions, which is expected to provide a reference for the development of multi-target drugs. This paper reviews the application of network biology in traditional Chinese medicine in six aspects, in expectation to provide a reference to the modernized study of traditional Chinese medicine.

    In this paper, the consensus problem for leader-following linear multi-agent systems with external disturbances is investigated. Brownian motions are used to describe exogenous disturbances. A distributed tracking controller based on Riccati inequalities with an adaptive law for adjusting coupling weights between neighbouring agents is designed for leader-following multi-agent systems under fixed and switching topologies. In traditional distributed static controllers, the coupling weights depend on the communication graph. However, coupling weights associated with the feedback gain matrix in our method are updated by state errors between neighbouring agents. We further present the stability analysis of leader-following multi-agent systems with stochastic disturbances under switching topology. Most traditional literature requires the graph to be connected all the time, while the communication graph is only assumed to be jointly connected in this paper. The design technique is based on Riccati inequalities and algebraic graph theory. Finally, simulations are given to show the validity of our method.

    Full Text Available Objective: To determine the efficacy of the stair-step protocol (SSP using clomiphene citrate (CC in patients with polycystic ovary syndrome (PCOS and compare it with traditional regimen. Design: This was randomized control trial. Setting: Infertility Clinic. Patient(s: Sixty infertile PCOS women. Intervention(s: Patients were randomized into the study (SSP – 30 patients and control group (traditional protocol – 30 patients. In the SSP, patients were treated with CC 50 mg/day for 5 days and in nonresponsive patients, the dosage was increased to 100 mg/day for 5 days in the same cycle. Maximum dose of 150 mg was given until the dominant follicle was generated. In control group, the dose increment in nonovulatory cases was done in subsequent cycle. Ultrasonography follow-up was done to detect ovulation. Main Outcome Measure(s: Ovulation rate and duration of treatment. Results: Ovulation (66.7% vs. 50% respectively and pregnancy rates (26.7% vs. 15.7% were similar between the stair step and the control group. The duration of treatment was significantly shorter in stair step compared to traditional protocol (17.23 vs. 53 days. CC 100 mg was the most effective dose for ovulation in either group. There were no significant differences in the systemic side effect. Conclusions: By using SSP, effective treatment is provided in significantly shorter time period without any detrimental effect on the ovulation and pregnancy rates.

    The use of resin-based luting agents is ever expanding with the development of adhesive dentistry. A multitude of different adhesive systems are used with resin-based luting agents, and new products are introduced to the market frequently. Traditional adhesives generally required a multiple step bonding procedure prior to cementing with active resin-based luting materials; however, combined agents offer a simple application procedure. Self-etching 'all-in-one' systems claim that there is no need for the use of a separate adhesive process. The following review addresses the advantages and disadvantages of the available adhesive systems used with resin-based luting agents.

    The Stewart model for analyzing acid-base disturbances emphasizes serum albumin levels, which are ignored in the traditional Boston model. We compared data derived using the Stewart model to those using the Boston model in patients with nephrotic syndrome. Twenty-nine patients with nephrotic syndrome and six patients without urinary protein or acid-base disturbances provided blood and urine samples for analysis that included routine biochemical and arterial blood gas tests, plasma renin activity, and aldosterone. The total concentration of non-volatile weak acids (A TOT ), apparent strong ion difference (SIDa), effective strong ion difference (SIDe), and strong ion gap (SIG) were calculated according to the formulas of Agrafiotis in the Stewart model. According to the Boston model, 25 of 29 patients (90%) had alkalemia. Eighteen patients had respiratory alkalosis, 11 had metabolic alkalosis, and 4 had both conditions. Only three patients had hyperreninemic hyperaldosteronism. The Stewart model demonstrated respiratory alkalosis based on decreased PaCO 2 , metabolic alkalosis based on decreased A TOT , and metabolic acidosis based on decreased SIDa. We could diagnose metabolic alkalosis or acidosis with a normal anion gap after comparing delta A TOT [(14.09 - measured A TOT ) or (11.77 - 2.64 × Alb (g/dL))] and delta SIDa [(42.7 - measured SIDa) or (42.7 - (Na + K - Cl)]). We could also identify metabolic acidosis with an increased anion gap using SIG > 7.0 (SIG = 0.9463 × corrected anion gap-8.1956). Patients with nephrotic syndrome had primary respiratory alkalosis, decreased A TOT due to hypoalbuminemia (power to metabolic alkalosis), and decreased levels of SIDa (power to metabolic acidosis). We could detect metabolic acidosis with an increased anion gap by calculating SIG. The Stewart model in combination with the Boston model facilitates the analysis of complex acid-base disturbances in nephrotic syndrome.

    Dry eye syndrome can be difficult to manage in severe or refractory cases. In patients in whom traditional treatments have limited efficacy, alternative treatments may be considered for dry eye syndrome, including scleral lenses. The present review summarizes the evidence regarding scleral lens use in dry eye syndrome. Scleral lenses have become a viable option for severe dry eye syndrome, and have been shown to be efficacious and well tolerated, with most reports citing improved visual acuity and relief of symptoms. Currently, there are 18 manufacturers of scleral lenses, although published reports on scleral lenses primarily focus on the BostonSight PROSE and the Jupiter Lens. Scleral lenses are efficacious and well tolerated for use in severe dry eye syndrome. Further research is needed to compare different sizes and types of lenses, and to standardize outcome measures.

    A patient with Weill-Marchesani syndrome and angle-closure glaucoma had persistent appositional closure after laser iridotomy that was unrelieved by topical application of either miotic or cycloplegic agents. Argon laser peripheral iridoplasty successfully opened the angle. The patient's sister also had Weill-Marchesani syndrome and angle closure unrelieved by laser iridotomy. Angle closure in Weill-Marchesani syndrome and the response to laser iridotomy and treatment with either miotic or cycloplegic agents may be complex and depends on the relative proportion of pupillary block as a mechanism underlying the angle closure, the functional status of the zonular apparatus, and the degree of angle crowding by the peripheral iris in the presence or absence of peripheral anterior synechiae.

    The prevalence of metabolic syndrome has reached epidemic levels in the Samoan Islands. In this cross-sectional study conducted in 2002-2003, dietary patterns were described among American Samoan (n = 723) and Samoan (n = 785) adults (> or =18 y) to identify neo-traditional and modern eating patterns and to relate these patterns to the presence of metabolic syndrome using Adult Treatment Panel III criteria. The neo-traditional dietary pattern, similar across both polities, was characterized by high intake of local foods, including crab/lobster, coconut products, and taro, and low intake of processed foods, including potato chips and soda. The modern pattern, also similar across both polities, was characterized by high intake of processed foods such as rice, potato chips, cake, and pancakes and low intake of local foods. The neo-traditional dietary pattern was associated with significantly higher serum HDL-cholesterol in American Samoa (P-trend = 0.05) and a decrease in abdominal circumference in American Samoa and Samoa (P-trend = 0.004 and 0.01, respectively). An inverse association was found with metabolic syndrome, although it did not reach significance (P = 0.23 in American Samoa; P = 0.13 in Samoa). The modern pattern was significantly positively associated with metabolic syndrome in Samoa (prevalence ratio = 1.21 for the fifth compared with first quintile; 95% CI: 0.93.1.57; P-trend = 0.05) and with increased serum triglyceride levels in both polities (P fiber, seafood, and coconut products may help to prevent growth in the prevalence of metabolic syndrome in the Samoan islands.

    To evaluate the prevalence of traditional risk factors in patients with primary antiphospholipid syndrome (APS) in comparison to those with systemic lupus erythematosus-secondary APS. Transversal study of 96 APS patients (Sapporo's criteria). Demographic and clinical data, cardiovascular risk factors and drug use were investigated. Thirty-nine Primary APS and 57 secondary APS were included. The groups did not differ regarding age (38.5 +/- 9.9 vs. 39.4 +/- 10.5 years, p=0.84) and female gender (84.6 vs. 96.5%, p=0.06), respectively. Arterial events were more observed in primary than secondary APS (59 vs. 36.8%, p=0.04) patients. No difference was seen concerning venous and obstetric events. In regard to traditional risk factors for cardiovascular disease, both groups were comparable related to current or previous smoking, sedentarism, family history for coronary disease, systemic hypertension, diabetes mellitus, overweight and obesity. The frequencies of altered lipid profiles were alike in the two groups, except for a higher prevalence of low HDL-c levels in primary APS group (84.6 vs. 45.5%, p=0.0001). Concerning drug use, no significant differences were observed related to chloroquine and statin use, however the secondary APS patients had a higher rate of prednisone use (10.2 vs. 57.9%, pAPS, except for a high frequency of low HDL-c in primary APS patients.

    The susceptibilities to antimicrobial agents of and distributions of antiseptic resistance genes in methicillin-resistant Staphylococcus aureus (MRSA) strains isolated between 1999 and 2004 in Japan were examined. The data of MRSA strains that are causative agents of impetigo and staphylococcal scalded skin syndrome (SSSS) were compared with those of MRSA strains isolated from patients with other diseases. The susceptibilities to antiseptic agents in MRSA isolates from patients with impetigo and SSSS were higher than those in MRSA isolates from patients with other diseases. The distribution of the qacA/B genes in MRSA strains isolated from patients with impetigo and SSSS (1.3%, 1/76) was remarkably lower than that in MRSA strains isolated from patients with other diseases (45.9%, 95/207). Epidemiologic typings of staphylococcal cassette chromosome mec (SCCmec) and pulsed-field gel electrophoresis (PFGE) showed that MRSA strains isolated from patients with impetigo and SSSS had type IV SCCmec (75/76), except for one strain, and 64.5% (49/76) of the strains had different PFGE types. In addition, the patterns of restriction digestion of all tested qacA/B plasmid in MRSA isolates having different PFGE types were identical. The results showed that a specific MRSA clone carrying qacA/B was not prevalent, but qacA/B was spread among health care-associated MRSA strains. Therefore, it was concluded that the lower distribution rate of qacA/B resulted in higher susceptibilities to cationic antiseptic agents in MRSA isolated from patients with impetigo and SSSS.

Methods: Fifty women diagnosed with chronic pelvic pain (CPP secondary to AMPS were evaluated by using a questionnaire based on the theories of “yin-yang,” “zang-fu”, and “five elements”. We assessed the following aspects of the illness: symptomatology; specific location of myofascial trigger points (MTrPs; onset, cause, duration and frequency of symptoms; and patient and family history. The patients tongues, lips, skin colors, and tones of speech were examined. Patients were questioned on various aspects related to breathing, sweating, sleep quality, emotions, and preferences related to color, food, flavors, and weather or seasons. Thirst, gastrointestinal dysfunction, excreta (feces and urine, menstrual cycle, the five senses, and characteristic pain symptoms related to headache, musculoskeletal pain, abdomen, and chest were also investigated. Results: Patients were between 22 and 56 years old, and most were married (78%, possessed a elementary school (66%, and had one or two children (76%. The mean body mass index and body fat were 26.86 kg/ cm2 (range: 17.7 — 39.0 and 32.4% (range: 10.7 — 45.7, respectively. A large majority of women (96% exhibited alterations in the kidney meridian, and 98% had an altered gallbladder meridian. We observed major changes in the kidney and the gallbladder Qi meridians in 76% and 62% of patients, respectively. Five of the twelve meridians analyzed exhibited Qi patterns similar to pelvic innervation Qi and meridians, indicating that the paths of some of these meridians were directly related to innervation of the pelvic floor and abdominal region. Conclusion: The women in this study showed changes in the behavior of the energy meridians, and the paths of some of the meridians were directly related to innervation of the

    Sasang constitutional medicine (SCM), traditional Chinese medicine (TCM) and Ayurveda are three different forms of Asian traditional medicine. Although these traditions share a lot in common as holistic medicines, the different philosophical foundations found in each confer distinguishing attributes and unique qualities. SCM is based on a constitution-based approach, and is in this way relatively more similar to the Ayurvedic tradition than to the TCM, although many of the basic SCM theories were originally derived from TCM, a syndrome-based medicine. SCM and TCM use the same botanical materials that are distributed mainly in the East Asian region, but the basic principles of usage and the underlying rationale are completely different from each other. Meanwhile, the principles of the Ayurvedic use of botanical resources are very similar to those seen in SCM, but the medicinal herbs used in Ayurveda generally originate from the West Asian region which displays a different spectrum of flora.

    Adrenal imaging in the past has been limited in its clinical application by the long interval between administration of dose and visualization of adrenal glands. We review our experience with the use of a newer labeling agent, NP-59, in 29 patients with various adrenal disorders and in 4 normal subjects. With this agent, identification of adrenal lesions is possible with a high degree of accuracy, and diagnostic information is usually available within 48 hrs. NP-59 is particularly useful in evaluating primary aldosteronism and selected cases of Cushing's syndrome

  5. Diagnostic Overlap between Fanconi Anemia and the Cohesinopathies: Roberts Syndrome and Warsaw Breakage Syndrome

    2010-01-01

    Full Text Available Fanconi anemia (FA is a recessively inherited disease characterized by multiple symptoms including growth retardation, skeletal abnormalities, and bone marrow failure. The FA diagnosis is complicated due to the fact that the clinical manifestations are both diverse and variable. A chromosomal breakage test using a DNA cross-linking agent, in which cells from an FA patient typically exhibit an extraordinarily sensitive response, has been considered the gold standard for the ultimate diagnosis of FA. In the majority of FA patients the test results are unambiguous, although in some cases the presence of hematopoietic mosaicism may complicate interpretation of the data. However, some diagnostic overlap with other syndromes has previously been noted in cases with Nijmegen breakage syndrome. Here we present results showing that misdiagnosis may also occur with patients suffering from two of the three currently known cohesinopathies, that is, Roberts syndrome (RBS and Warsaw breakage syndrome (WABS. This complication may be avoided by scoring metaphase chromosomes—in addition to chromosomal breakage—for spontaneously occurring premature centromere division, which is characteristic for RBS and WABS, but not for FA.

    Traditional Chinese medicine (TCM) is a unique and complex medical system that has developed over thousands of years. This article studies the problem of automatically extracting meaningful relations of entities from TCM literature, for the purposes of assisting clinical treatment or poly-pharmacology research and promoting the understanding of TCM in Western countries. Instead of separately extracting each relation from a single sentence or document, we propose to collectively and globally extract multiple types of relations (eg, herb-syndrome, herb-disease, formula-syndrome, formula-disease, and syndrome-disease relations) from the entire corpus of TCM literature, from the perspective of network mining. In our analysis, we first constructed heterogeneous entity networks from the TCM literature, in which each edge is a candidate relation, then used a heterogeneous factor graph model (HFGM) to simultaneously infer the existence of all the edges. We also employed a semi-supervised learning algorithm estimate the model's parameters. We performed our method to extract relations from a large dataset consisting of more than 100,000 TCM article abstracts. Our results show that the performance of the HFGM at extracting all types of relations from TCM literature was significantly better than a traditional support vector machine (SVM) classifier (increasing the average precision by 11.09%, the recall by 13.83%, and the F1-measure by 12.47% for different types of relations, compared with a traditional SVM classifier). This study exploits the power of collective inference and proposes an HFGM based on heterogeneous entity networks, which significantly improved our ability to extract relations from TCM literature. © The Author 2015.

    Full Text Available The last ten years of the XX century has been the witnesses of the apparition of a new scientific field, which is usually defined as the study of “Complex adaptive systems”. This field, generic named Complexity Sciences, shares its subject, the general proprieties of complex systems across traditional disciplinary boundaries, with cybernetics and general systems theory. But the development of Complexity Sciences approaches is determined by the extensive use of Agent-Based-Models (ABM as a research tool and an emphasis on systems, such as markets, populations or ecologies, which are less integrated or “organized” than the ones, such as companies and economies, intensively studied by the traditional disciplines. For ABM, a complex system is a system of individual agents who have the freedom to act in ways that are not always totally predictable, and whose actions are interconnected such that one agent’s actions changes the context (environment for other agents. These are many examples of such complex systems: the stock market, the human body immune system, a business organization, an institution, a work-team, a family etc.

    Mixed cryoglobulinemia syndrome (MC) is a systemic vasculitis involving kidneys, joints, skin, and peripheral nerves. While many autoimmune, lymphoproliferative, and neoplastic disorders have been associated with this disorder, hepatitis C virus (HCV) is known to be the etiologic agent in the majority of patients. Therefore, clinical research has focused on anti-viral drugs and, more recently, on the new, highly potent Direct-acting Antiviral Agents (DAAs). These drugs assure sustained virologic response (SVR) rates >90%. Nevertheless, data on their efficacy in patients with HCV-associated cryoglobulinemic vasculitis are disappointing, possibly due to the inability of the drugs to suppress the immune-mediated process once it has been triggered.Despite the potential risk of exacerbation of the infection, immunosuppression has traditionally been regarded as the first-line intervention in cryoglobulinemic vasculitis, especially if renal involvement is severe. Biologic agents have raised hopes for more manageable therapeutic approaches, and Rituximab (RTX), an anti CD20 monoclonal antibody, is the most widely used biologic drug. It has proved to be safer than conventional immunosuppressants, thus substantially changing the natural history of HCV-associated cryoglobulinemic vasculitis by providing long-term remission, especially with intensive regimens.The present review focuses on the new therapeutic opportunities offered by the combination of biological drugs, mainly Rituximab, with DAAs.

    Children with Down syndrome (DS) and acute leukemias acute have unique biological, cytogenetic, and intrinsic factors that affect their treatment and outcome. Myeloid leukemia of Down syndrome (ML-DS) is associated with high event-free survival (EFS) rates and frequently preceded by a preleukemia condition, the transient abnormal hematopoiesis (TAM) present at birth. For acute lymphoblastic leukemia (ALL), their EFS and overall survival are poorer than non-DS ALL, it is important to enroll them on therapeutic trials, including relapse trials; investigate new agents that could potentially improve their leukemia-free survival; and strive to maximize the supportive care these patients need.

    2012-12-01

    Polycystic ovarian syndrome (PCOS) is a disorder of androgen excess and ovarian dysfunction. Hirsutism and elevated free testosterone levels are the most consistent signs of the androgen excess. Irregular, infrequent, or absent menses and infertility are symptoms of ovulatory dysfunction. Obesity is also a feature of this syndrome and contributes to associated metabolic abnormalities. Lifestyle modification should be the first treatment and is effective in reducing the signs and symptoms. The ovulatory infertility associated with PCOS can be overcome in most cases with oral (clomiphene citrate or letrozole) or injectable (gonadotropins) agents. Surgical intervention is reserved for cases resistant to medical management. Copyright © 2012 Elsevier Inc. All rights reserved.

  12. Excision repair in ataxia telangiectasia, Fanconi's anemia, Cockayne syndrome, and Bloom's syndrome after treatment with ultraviolet radiation and N-acetoxy-2-acetylaminofluorene

    Ahmed, F.E.; Setlow, R.B.

    1978-01-01

    Excision repair of damage due to ultraviolet radiation, N-acetoxy-2-acetylaminofluorene and a combination of both agents was studied in normal human fibroblasts and various cells from cancer prone patients (ataxia telangiectasia, Fanconi's anemia, Cockayne syndrome and Bloom's syndrome). Three methods giving similar results were used: unscheduled DNA synthesis by radioautography, photolysis of bromodeoxyuridine incorporated into parental DNA during repair, and loss of sites sensitive to an ultraviolet endonuclease. All cell lines were proficient in repair of ultraviolet and acetoxy acetylaminofluorene damage and at saturation doses of both agents repair was additive. We interpret these data as indicating that the rate limiting step in excision repair of ultraviolet and acetoxy acetylaminofluorene is different and that there are different enzyme(s) working on incision of both types of damages.

    Serotonin syndrome (SS) can occur when linezolid is combined with other serotonergic agents. We report a case of possible SS in an elderly patient receiving linezolid in combination with carbidopa-levodopa (CL). Although certain classes of agents are commonly reported as causing SS among patients receiving linezolid, there are no specific case reports detailing this reaction with CL. Linezolid combined with CL should generally be avoided; however, if linezolid must be used, discontinuation of other agents with serotonergic activity is recommended with careful monitoring for signs and symptoms of SS. © 2016 John Wiley & Sons Ltd.

    2010-01-01

    Synopsis Cushing’s syndrome is caused by prolonged exposure to excess glucocorticoids. Diagnosis of Cushing’s syndrome involves a step-wise approach and establishing the cause can be challenging in some cases. Hypertension is present in about 80% of patients with Cushing’s syndrome and can lead to significant morbidity and mortality. Several pathogenic mechanisms have been proposed for glucocorticoid-induced hypertension including a functional mineralocorticoid excess state, up-regulation of the renin angiotensin system and deleterious effects of cortisol on the vasculature. Surgical excision of the cause of excess glucocorticoids remains the optimal treatment for Cushing’s syndrome. Anti-glucocorticoid and antihypertensive agents and steroidogenesis inhibitors can be used as adjunctive treatment modalities in preparation for surgery, and in cases where surgery is contraindicated or has not led to cure.

    Constipation is common, and its treatment is unsatisfactory. Although many agents have been tried, there are limited data to support their use. Our aim was to undertake a systematic review of the efficacy and safety of traditional medical therapies for chronic constipation and to make evidence-based recommendations. We searched the English literature for drug trials evaluating treatment of constipation by using MEDLINE and PUBMED databases from 1966 to 2003. Only studies that were randomized, conducted on adult subjects, and published as full manuscripts were included. Studies were assigned a quality score based on published methodology. Standard forms were used to abstract data regarding study design, duration, outcome measures, and adverse events. By using the cumulative evidence of published data for each agent, recommendations were made regarding their use following the United States Preventive Services Task Force guidelines. Good evidence (Grade A) was found to support the use of polyethylene glycol (PEG) and tegaserod. Moderate evidence (Grade B) was found to support the use of psyllium, and lactulose. There was a paucity of quality data regarding many commonly used agents including milk of magnesia, senna, bisacodyl, and stool softeners. There is good evidence to support the use of PEG, tegaserod, lactulose, and psyllium. Surprisingly, there is a paucity of trials for many commonly used agents. These aspects should be considered when designing trials comparing new agents with traditional therapies because their use may not be well validated.

  19. Management Strategies for Aggressive Cushing's Syndrome: From Macroadenomas to Ectopics

    Directory of Open Access Journals (Sweden)

    Carlotta Pozza

    2012-01-01

    Full Text Available Cushing’s syndrome (CS is a rare but severe clinical condition represented by an excessive endogenous cortisol secretion and hence excess circulating free cortisol, characterized by loss of the normal feedback regulation and circadian rhythm of the hypothalamic-pituitary axis due to inappropriate secretion of ACTH from a pituitary tumor (Cushing’s disease, CD or an ectopic source (ectopic ACTH secretion, EAS. The remaining causes (20% are ACTH independent. As soon as the diagnosis is established, the therapeutic goal is the removal of the tumor. Whenever surgery is not curative, management of patients with CS requires a major effort to control hypercortisolemia and associated symptoms. A multidisciplinary approach that includes endocrinologists, neurosurgeons, oncologists, and radiotherapists should be adopted. This paper will focus on traditional and novel medical therapy for aggressive ACTH-dependent CS. Several drugs are able to reduce cortisol levels. Their mechanism of action involves blocking adrenal steroidogenesis (ketoconazole, metyrapone, aminoglutethimide, mitotane, etomidate or inhibiting the peripheral action of cortisol through blocking its receptors (mifepristone “RU-486”. Other drugs include centrally acting agents (dopamine agonists, somatostatin receptor agonists, retinoic acid, peroxisome proliferator-activated receptor γ “PPAR-γ” ligands and novel chemotherapeutic agents (temozolomide and tyrosine kinase inhibitors which have a significant activity against aggressive pituitary or ectopic tumors.

    Full Text Available Refractoriness to growth factor therapy is commonly associated with inferior outcome in patients with low-risk myelodysplastic syndrome (LR-MDS who require treatment for cytopenias. However, the mechanisms leading to refractoriness are unknown. Here we describe a clinically depressed 74-year-old male with refractory cytopenia with multilineage dysplasia (RCMD and documented growth factor refractory anemia after erythropoeisis stimulating agent (ESA therapy, who attained transfusion and growth factor independence after the addition of sertraline to his medication regimen. Our case demonstrates hematological improvement-erythroid (HI-E in growth factor refractory, low risk MDS and highlights a potential mechanistic link between common inflammatory diseases and LR-MDS.

    Wolff-Parkinson-White (WPW) syndrome is a rare pre-excitation syndrome which develops when atrioventricular conduction occurs through a pathologic accessory pathway known as the bundle of Kent instead of atrioventricular node, hence resulting in tachycardia. Patients with WPW syndrome may experience various symptoms arising from mild-to-moderate chest disease, palpitations, hypotension, and severe cardiopulmonary dysfunction. These patients are most often symptomatic because of cardiac arrhythmias. In this case report, we present an uneventful anesthetic management of a pregnant patient with WPW syndrome undergoing cesarean delivery. A 23-year-old American Society of Anesthesiologists class 2 pregnant patient was diagnosed with WPW syndrome. Her preoperative 12-lead electrocardiogram showed a sinus rhythm at 82 beats per minute, a delta wave, and a short PR interval. After an uneventful surgery, sugammadex 2mg/kg was administered as a reversal agent instead of neostigmine. Then she was discharged to her obstetrics service. Serious hemodynamic disorders may occur in patients with WPW syndrome due to development of fatal arrhythmias. Neostigmine used as a reversal agent in general anesthesia can trigger such fatal arrhythmias by leading changes in cardiac conduction. We believe that sugammadex, which is safely used in many areas in the scope of clinical practice, can be also used for patients diagnosed with WPW syndrome. Copyright © 2016 Elsevier Inc.

  5. Hypersensitivity to DNA-damaging agents in primary degenerations of excitable tissue

    International Nuclear Information System (INIS)

    Robbins, J.H.

    1983-01-01

    Defects in DNA-repair mechanisms render xeroderma pigmentosum cells hypersensitive to killing by the uv-type of DNA-damaging agent. Some xeroderma pigmentosum patients develop a primary neuronal degeneration, and cell lines from patients with the earliest onset of neurodegeneration are the most sensitive to killing by uv radiation. These findings led to the neuronal DNA integrity theory which holds that when the integrity of neuronal DNA is destroyed by the accumulation of unrepaired DNA damaged spontaneously or by endogenous metabolites, the neurons will undergo a primary degeneration. Cells from patients with Cockayne syndrome, a demyelinating disorder with a primary retinal degeneration, are also hypersensitive to the uv-type of DNA-damaging agent. Cells from patients with the primary neuronal degeneration of ataxia telangiectasia are hypersensitive to the x-ray-type of DNA-damaging agent. Cells from other patients with primary degeneration of excitable tissue also have hypersensitivity to the x-ray-type of DNA-damaging agent. These disorders include (1) primary neuronal degenerations which are either genetic (e.g., Huntington disease, familial dysautonomia, Friedreich ataxia) or sporadic (e.g., Alzheimer disease, Parkinson disease), (2) primary muscle degenerations (e.g., Duchenne muscular dystrophy), and (3) a primary retinal degeneration (Usher syndrome). Death of excitable tissue in vivo in these radiosensitive diseases may result from unrepaired DNA. This hypersensitivity provides the basis for developing suitable presymptomatic and prenatal tests for these diseases, for elucidating their pathogenesis, and for developing future therapies. 119 references, 3 figures, 3 tables

    1982-01-01

    Fibroblast cell strains derived from different patients all afflicted with genetic predisposing to the development of intestinal polyposis and cancer were tested for their sensitivity to the lethal effects of the DNA alkylating agents methylmethanesulfonate (MMS), ethyl methanesulfonate, N-methyl-N'-nitro-N-nitrosoguanidine, and 4-nitroquinoline 1-oxide. The genetic syndromes studied were: (a) adenomatosis of the colon and rectum only, an autosomal dominant trait; (b) Turcot's syndrome, a rare autosomal recessive polyposis syndrome also characterized by central nervous system tumors; and (c) Gardner's syndrome, an autosomal dominant syndrome which, in addition to intestinal polyposis, is also clinically characterized by osteomas and soft tissue tumors. Fibroblasts from a patient with Turcot's syndrome were hypersensitive to MMS, having a D0 value of 0.24 mM (p less than 0.01) versus the normal average D0 of 0.36 mM and a D10 value of 0.95 mM (p less than 0.01) compared with the normal average value of 1.3 mM. Fibroblasts from the Gardner's syndrome proband were moderately sensitive to MMS, ethyl methanesulfonate, and N-methyl-N'-nitro-N-nitrosoguanidine due to significant differences of D10 values of 0.60 mM (p less than 0.01), 15 mM (p less than 0.01), and 4.8 microM (p less than 0.025), respectively, versus the normal average values of 1.3 mM, 28 mM, and 9.4 microM. Fibroblasts from the clinically affected Gardner's syndrome daughter of the proband were significantly more sensitive to MMS treatment, D0 of 0.22 mM (p less than 0.01) versus the normal average D0 of 0.36 mM and a D10 of 0.97 mM (p less than 0.01) versus the normal average.

    Agent-based modeling and simulation (ABMS) is a new approach to modeling systems comprised of autonomous, interacting agents. ABMS promises to have far-reaching effects on the way that businesses use computers to support decision-making and researchers use electronic laboratories to support their research. Some have gone so far as to contend that ABMS 'is a third way of doing science,' in addition to traditional deductive and inductive reasoning (Axelrod 1997b). Computational advances have made possible a growing number of agent-based models across a variety of application domains. Applications range from modeling agent behavior in the stock market, supply chains, and consumer markets, to predicting the spread of epidemics, the threat of bio-warfare, and the factors responsible for the fall of ancient civilizations. This tutorial describes the theoretical and practical foundations of ABMS, identifies toolkits and methods for developing agent models, and illustrates the development of a simple agent-based model of shopper behavior using spreadsheets.

    Neuroleptic malignant syndrome (NMS) and serotonin syndrome (SS) are serious medical conditions associated with commonly prescribed psychiatric medications. Although the mechanisms differ, they can be clinically difficult to distinguish. We report a case of a pediatric patient with complicated psychiatric history that developed features of both syndromes in the setting of polypharmacy. A 12-year-old boy with a history of developmental delay, attention-deficit hyperactivity disorder, and posttraumatic stress disorder presented to the emergency department with behavior changes consisting of delayed reactions, gait instability, drooling, and slowed movements. Ten days before presentation, his outpatient psychiatrist had made multiple medication changes including discontinuation of cyproheptadine (an appetite stimulant) and initiation of aripiprazole. On arrival, the patient was noted to be tachycardia and hypertensive for age. He was disoriented, intermittently agitated, and tremulous with increased tonicity, clonus in the lower extremities, and mydriasis. He was supportively treated with lorazepam and intravenous fluids while discontinuing potential offending agents. His course was complicated by hypertension and agitation managed with dexmedetomidine infusion and benzodiazepines. His mental status, tremors, and laboratory values began to improve over the next 2 days, and eventually transitioned to the inpatient psychiatric unit on hospital day 7. Diagnosis of NMS or SS can be difficult when there is overlap between syndromes, particularly in the setting of multiple potential offending agents or underlying developmental delay. In addition, pediatric patients may present atypically as compared with adult patients with the same condition. The use of antipsychotic medications for young children with behavioral problems has risen dramatically in the last decade, increasing their risk for developing SS or NMS.

    Etanercept and other anti-TNF-alpha agents have been indicated as a therapeutic option in severe drug reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis. Etanercept has been shown to quickly reduce the detachment of the epidermis and shorten healing time. Cases of etanercept-induced severe adverse drug reactions were also described. A 27-year-old woman with a 4-year history of etanercept and sulfasalazine treatment for rheumatoid arthritis was admitted with Stevens-Johnson syndrome. The patient received one dose of an OTC drug containing acetaminophen, phenylephrine and pheniramine two days prior to developing fist mucocutaneous symptoms. The most probable causative agent was paracetamol. Throughout the successful routine therapy of Stevens-Johnson syndrome etanercept therapy was continued. Sulfosalazin administration was stopped and administered again after recovery with no recurrence of the skin and mucosal symptoms. This case indicates that there is no justification for discontinuation of long-term anti-TNF-alpha treatment in patients who develop Stevens- Johnson syndrome / toxic epidermal necrolysis.

    Wernicke encephalopathy is a disease that constitutes a medical emergency, but one that can be reversed with thiamine repletion if it is recognized early. Patients with cancer have a high risk of Wernicke encephalopathy because of malnutrition, the use of chemotherapeutic agents, and disease progression. Korsakoff syndrome can follow or accompany Wernicke encephalopathy. Although patients can recover from Wernicke encephalopathy via rapid repletion of thiamine, few patients recover from Korsakoff syndrome. Here, the case of a 76-year-old female patient who had primary peritoneal cancer and developed Wernicke-Korsakoff syndrome as a result of prolonged nutritional imbalance and fast-growing tumor cells is reported. The patient's neurologic symptoms improved, but she did not recover from the psychiatric effects of the disease.

    To systematically review the efficacy and safety of Traditional Chinese Medicine (TCM) interventions, compared with control interventions (placebo or conventional Western medical therapy), in the treatment of acquired immunodeficiency syndrome (AIDS). Electronic databases including PubMed, the Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wanfang Data were searched to identify relevant randomized controlled trials (RCTs) published as of May 2012. Studies were selected according to the specified inclusion and exclusion criteria and then subjected to methodological quality assessment, data extraction, and meta-analysis according to the Cochrane Handbook for Systematic Reviews of Interventions. Twelve RCTs involving 881 patients with AIDS were included. Methodological quality assessment showed that two were high-quality, two were moderate-quality, and eight were low-quality. Meta-analysis showed that TCM interventions were associated with significantly reduced plasma viral load compared with placebo [odds ratio OR = 2.46, 95% confidence interval CI (1.02, 5.94); P = 0.04]. However, the reductions in plasma viral load significantly favored conventional Western medical therapy alone over integrated traditional Chinese and Western medical therapy [OR = 0.16, 95% CI (0.05, 0.55); P = 0.004]. Patients receiving TCM interventions had significantly higher CD4+ T lymphocyte counts compared with those on placebo [OR = 2.54, 95% CI (1.40, 4.60); P = 0.002]. In addition, TCM interventions were significantly more likely to have improved clinical symptoms [OR = 2.82, 95% CI (1.85, 4.31); P risk of adverse events (AEs) compared with control interventions [OR = 1.87, 95% CI (0.58, 6.01); P = 0.29]. Current evidence suggests that TCM interventions are significantly more effective than placebo in reducing plasma viral load and increasing CD4+ T lymphocyte count in patients with AIDS. When compared with conventional Western medical therapy, TCM interventions

    Background Over one hundred different pharmaceutical dosage forms have been recorded in literatures of Traditional Persian Medicine among which nasal forms are considerable. Objectives This study designed to derive the most often applied nasal dosage forms together with those brief clinical administrations. Materials and Methods In the current study remaining pharmaceutical manuscripts of Persia during 9th to 18th century AD have been studied and different dosage forms related to nasal application of herbal medicines and their therapeutic effects were derived. Results By searching through pharmaceutical manuscripts of medieval Persia, different nasal dosage forms involving eleven types related to three main groups are found. These types could be derived from powder, solution or liquid and gaseous forms. Gaseous form were classified into fumigation (Bakhoor), vapor bath (Enkebab), inhalation (Lakhlakheh), aroma agents (Ghalieh) and olfaction or smell (Shomoom). Nasal solutions were as drops (Ghatoor), nasal snuffing drops (Saoot) and liquid snuff formulations (Noshoogh). Powders were as nasal insufflation or snorting agents (Nofookh) and errhine or sternutator medicine (Otoos). Nasal forms were not applied only for local purposes. Rather systemic disorders and specially CNS complications were said to be a target for these dosage forms. Discussion While this novel type of drug delivery is known as a suitable substitute for oral and parenteral administration, it was well accepted and extensively mentioned in Persian medical and pharmaceutical manuscripts and other traditional systems of medicine as well. Accordingly, medieval pharmaceutical standpoints on nasal dosage forms could still be an interesting subject of study. Therefore, the current work can briefly show the pharmaceutical knowledge on nasal formulations in medieval Persia and clarify a part of history of traditional Persian pharmacy. PMID:24624204

    Pseudogymnoascus destructans, the fungus that causes white-nose syndrome in hibernating bats, has spread across eastern North America over the past decade and decimated bat populations. The saprotrophic growth of P. destructans may help to perpetuate the white-nose syndrome epidemic, and recent model predictions suggest that sufficiently reducing the environmental growth of P. destructans could help mitigate or prevent white-nose syndrome-associated bat colony collapse. In this study, we scre...

    Full Text Available In this paper, we propose a traffic management system with agents acting on behalf autonomous vehicle at the crossroads. Alternatively to existing solutions based on usage of semiautonomous control systems with the control unit, proposed in this paper algorithm apply the principles of decentralized multi-agent control. Agents during their collaboration generate intersection plan and determinate the optimal order of road intersection for a given criterion based on the exchange of information about them and their environment. The paper contains optimization criteria for possible routes selection and experiments that perform in order to estimate the proposed model. Experiment results show that this model can significantly reduce traffic density compared to the traditional traffic management systems. Moreover, the proposed algorithm efficiency increases with road traffic density. Furthermore, the availability of control unit in the system significantly reduces the negative impact of possible failures and hacker attacks.

    Metabolic syndrome (MS) is a very common medical problem worldwide. It includes obesity, hypertension, hyperglycemia, and abnormal levels of triglycerides and high-density lipoprotein cholesterol. It is closely associated with insulin resistance and may lead to diabetes mellitus, liver diseases, or cardiovascular diseases. Corn silk (CS), a traditional Chinese medicine, has been reported to have multiple beneficial effects, including hypotensive, anti-diabetic, and hypolipidemic properties. This suggests that corn silk could be used to treat or prevent metabolic syndrome. In this review, we will discuss the potential role of corn silk in different components of metabolic syndrome.

    2018-04-01

    Full Text Available Agent-Based Models (ABMs assist with studying emergent collective behavior of individual entities in social, biological, economic, network, and physical systems. Data provenance can support ABM by explaining individual agent behavior. However, there is no provenance support for ABMs in a distributed setting. The Multi-Agent Spatial Simulation (MASS library provides a framework for simulating ABMs at fine granularity, where agents and spatial data are shared application resources in a distributed memory. We introduce a novel approach to capture ABM provenance in a distributed memory, called ProvMASS. We evaluate our technique with traditional data provenance queries and performance measures. Our results indicate that a configurable approach can capture provenance that explains coordination of distributed shared resources, simulation logic, and agent behavior while limiting performance overhead. We also show the ability to support practical analyses (e.g., agent tracking and storage requirements for different capture configurations.

    Lack of personalized learning is the key shortcoming of traditional e-Learning system. This paper analyzes the personal characters in e-Learning activity. In order to meet the personalized e-learning, a personalized e-learning system based on intelligent agent was proposed and realized in the paper. The structure of system, work process, the design of intelligent agent and the realization of intelligent agent were introduced in the paper. After the test use of the system by certain network school, we found that the system could improve the learner's initiative participation, which can provide learners with personalized knowledge service. Thus, we thought it might be a practical solution to realize self- learning and self-promotion in the lifelong education age.

  2. Tourette Syndrome: Update.

    2015-08-01

    Tourette Syndrome is a disorder characterized by tics. It typically begins in childhood and often improves in adult life. Tics are best described as voluntary movements made automatically so that volition is not ordinarily appreciated. There is frequently an urge, sometimes in the form of a specific sensory feeling (sensory tic), that precedes the tic. Patients say that they make the tic in order to reduce the urge, although shortly after the tic, the urge recurs. The sensory feeling may arise due to defective sensory habituation. Since tics relieve the urge, this can be considered rewarding, and repetition of this behavior may perpetuate the tic as a habit. Tourette Syndrome affects boys more than girls and is associated with attention deficit hyperactivity disorder and obsessive compulsive disorder. Although Tourette Syndrome often appears to be autosomal recessive in inheritance, it has been difficult to find any abnormal genes. There is a loss of inhibition in these patients and recent studies show abnormalities in brain GABA. Certainly there is also an abnormality in dopamine function and dopamine blocking agents are effective therapy. In severe drug-refractory patients, deep brain stimulation can be effective.

    Shifting current drug discovery tide from 'finding new drugs' to 'screening natural products' may be helpful for overcoming the 'more investment, fewer drugs' challenge. Traditional Chinese medicine (TCM), relying on natural products, has been playing a very important role in health protection and disease control for thousands of years in Asia, whose therapeutic efficacy is based on the 'synergism', that is, the combinational effects to be greater than that of the individual drug. Based on syndromes and patient characteristics and guided by the theories of TCM, formulae are designed to contain a combination of various kinds of crude drugs that, when combined, generally assume that a synergism of all ingredients will bring about the maximum of therapeutic efficacy. The increasing evidence has shown that multiple active component combinations of TCM could amplify the therapeutic efficacy of each agent, representing a new trend for modern medicine. However, the precise mechanism of synergistic action remains poorly understood. The present review highlights the concept of synergy and gives some examples of synergistic effects of TCM, and provides an overview of the recent and potential developments of advancing drug discovery towards more agile development of targeted combination therapies from TCM.

    Numerous studies have investigated a probable association between androgenetic alopecia (AGA) and cardiovascular disease (CVD) by researching limited and dispersed parameters. We aimed to evaluate both traditional and non-traditional cardiovascular risk factors in male patients with early-onset AGA. This case-control study included 68 participants: 51 male patients with early-onset AGA and 17 healthy male controls. Patients with AGA were classified into three groups according to the Hamilton-Norwood scale and the presence of vertex hair loss. Traditional and non-traditional cardiovascular risk factors were examined in all study subjects. Metabolic syndrome was diagnosed in 25 patients with AGA and in two control subjects (p baldness and controls (p < 0.05). The pulse-wave velocity values were also found to be significantly higher in patients (p < 0.001). A limitation of this study was the small study population. In conclusion, vertex pattern AGA appears to be a marker for early atherosclerosis. This finding supports the hypothesis that early-onset AGA alone could be an independent risk factor for CVD and metabolic syndrome.

    Human fibroblast cells from two different progeroid syndromes, Werner syndrome (WS) and progeria, were established as immortalized cell lines by transfection with plasmid DNA containing the SV40 early region. The lineage of each immortalized cell line was confirmed by VNTR analysis. Each of the immortalized cell lines maintained its original phenotype of slow growth. DNA repair ability of these cells was also studied by measuring sensitivity to killing by uv or the DNA-damaging drugs methyl methansulfonate, bleomycin, and cis-dichlorodiamine platinum. The results showed that both WS and progeria cells have normal sensitivity to these agents

    1980-01-01

    Renal failure without apparent cause (the hepatorenal syndrome) may develop in the course of cirrhosis of the liver. While the development of renal failure bears a poor prognosis, spontaneous recovery can occur. The data suggest that for the most part patients die in rather than of renal failure. The latter seems to be only part of a broader more fundamental disturbance. The pathogenesis of HRS is unknown, but the evidence supports an impairment of effective renal perfusion. The two major hypotheses concerning the nature of the impaired perfusion are that it is a physiologic response to alterations in the extrarenal circulation, and that there is an unidentified humoral agent(s) produced by or inadequately inactivated by or bypassing the diseased liver and causing circulatory changes in the kidney as well as in other organs. It is possible that both mechanisms are operative. Treatment is unsatisfactory and emphasis is presently best placed upon searching for more treatable causes of renal functional impairment in individual patients.

  8. Measuring SPIO and Gd contrast agent magnetization using 3 T MRI

    2011-01-01

    Traditional methods of measuring magnetization in magnetic fluid samples, such as vibrating sample magnetometry (VSM), are typically limited to maximum field strengths of about 1 T. This work demonstrates the ability of MRI to measure the magnetization associated with two commercial MRI contrast agents at 3 T by comparing analytical solutions to experimental imaging results for the field pattern associated with agents in cylindrical vials. The results of the VSM and fitted MRI data match closely. The method represents an improvement over VSM measurements since results are attainable at imaging field strengths. The agents investigated are Feridex, a superparamagnetic iron oxide suspension used primarily for liver imaging, and Magnevist, a paramagnetic, gadolinium-based compound used for tumors, inflammation and vascular lesions. MR imaging of the agents took place in sealed cylindrical vials in the presence of a surrounding volume of deionized water where the effects of the contrast agents had a measurable effect on the water's magnetization in the vicinity of the compartment of contrast agent. A pair of phase images were used to reconstruct a B0 fieldmap. The resultant B0 maps in the water region, corrected for shimming and container edge effects, were used to predict the agent's magnetization at 3 T. The results were compared with the results from VSM measurements up to 1.2 T and close correlation was observed. The technique should be of interest to those seeking quantification of the magnetization associated with magnetic suspensions beyond the traditional scope of VSM. The magnetization needs to be sufficiently strong (Ms≳50 Am2/kg Fe for Feridex and χm≳5 × 10−5 m3/kg Gd for Magnevist) for a measurable dipole field in the surrounding water. For this reason, the technique is mostly suitable for undiluted agents. PMID:19588450

    Full Text Available Background: The aim of this study was to compare the effectiveness of methadone detoxification with traditional method of gradual decrement in the abused amount of the refined opium dross (Shireh to control withdrawal syndrome in Shireh-addicted patients. Methods: In this study, two groups of Shireh addicts were compared. The first group was treated by methadone and the second group by gradual decrement in the amount of consumed Shireh. Those experiencing the adverse effects of the treatment were excluded from the study. Methadone dose was calculated based on the amount of the Shireh consumed and detoxification was performed during a 21-day period. In the second group, the amount of the consumed Shireh was gradually decreased within 21 days and some of the withdrawal symptoms were selected as indicators for patient evaluation. Results: A total of 35 patients (16 versus 19 patients in the first and second groups were evaluated. Their mean age was 43 ± 4 years and all were male. A statistically significant difference was found between these two groups in terms of severity and duration of withdrawal symptoms within the first five days and their duration after the 21st day of the onset of detoxification (P< 0.05. Conclusion: In comparison with methadone detoxification, traditional method of gradually decreasing the consumed amount of Shireh controls the severity and duration of withdrawal symptoms better in the course of detoxification.

    Cushing's syndrome is a rare disorder resulting from prolonged exposure to excess glucocorticoids. Early diagnosis and treatment of Cushing's syndrome is associated with a decrease in morbidity and mortality. Clinical presentation can be highly variable, and establishing the diagnosis can often be difficult. Surgery (resection of the pituitary or ectopic source of adrenocorticotropic hormone, or unilateral or bilateral adrenalectomy) remains the optimal treatment in all forms of Cushing's syndrome, but may not always lead to remission. Medical therapy (steroidogenesis inhibitors, agents that decrease adrenocorticotropic hormone levels or glucocorticoid receptor antagonists) and pituitary radiotherapy may be needed as an adjunct. A multidisciplinary approach, long-term follow-up, and treatment modalities customized to each individual are essential for optimal control of hypercortisolemia and management of comorbidities.

The differences in the Doppler indexes from twin-twin transfusion syndrome cases significantly exceeded those without this syndrome. This difference seemed to predict the risk of twin-twin transfusion syndrome, but the number of cases is too small for general conclusions. Treatment regimens for twin-twin transfusion syndrome have included bed rest, tocolytic agents and serial amniocenthesis for decompression in some cases.Neither serial amniocenthesis nor tocolytic agents use were associated with an improved survival rate in our study. Twin-twin transfusion syndrome can be diagnosed early in second trimester of pregnancy,but the survival rate remains low with the current methods of treatment. Survival was related to gestational age at delivery and birth weight. Twin-twin transfusion syndrome diagnosed before 28th weeks of gestation represents one of the most lethal conditions in perinatal medicine today.

    Full Text Available The influence of limited proteolysis of soy protein concentrate on proteinextractability, the composition of the extractable proteins, their emulsifying properties andsome nutritional properties were investigated. Traditional concentrate (alcohol leachedconcentrate was hydrolyzed using trypsin and pepsin as hydrolytic agents. Significantdifferences in extractable protein composition between traditional concentrate and theirhydrolysates were observed by polyacrylamide gel electrophoresis (PAGE and by SDSPAGE.All hydrolysates showed better extractability than the original protein concentrate,whereas significantly better emulsifying properties were noticed at modified concentratesobtained by trypsin induced hydrolysis. These improved properties are the result of twosimultaneous processes, dissociation and degradation of insoluble alcohol-induced proteinaggregates. Enzyme induced hydrolysis had no influence on trypsin-inibitor activity, andsignificantly reduced phytic acid content.

    2013-02-01

    Opioid withdrawal syndrome is a debilitating manifestation of opioid dependence and responds poorly to the available clinical therapies. Studies from various in vivo and in vitro animal models of opioid withdrawal syndrome have led to understanding of its pathobiology which includes complex interrelated pathways leading to adenylyl cyclase superactivation based central excitation. Advancements in the elucidation of opioid withdrawal syndrome mechanisms have revealed a number of key targets that have been hypothesized to modulate clinical status. The present review discusses the neurobiology of opioid withdrawal syndrome and its therapeutic target recptors like calcitonin gene related peptide receptors (CGRP), N-methyl-D-aspartate (NMDA) receptors, gamma aminobutyric acid receptors (GABA), G-proteingated inwardly rectifying potassium (GIRK) channels and calcium channels. The present review further details the potential role of second messengers like calcium (Ca2+) / calmodulin-dependent protein kinase (CaMKII), nitric oxide synthase, cytokines, arachidonic acid metabolites, corticotropin releasing factor, fos and src kinases in causing opioid withdrawal syndrome. The exploitation of these targets may provide effective therapeutic agents for the management of opioid dependence-induced abstinence syndrome.

METHODS One-hundred-eight records from a single center were retrospectively analyzed for Sturge-Weber syndrome brain involvement, epilepsy, Sturge-Weber syndrome neuroscores, and currently used anticonvulsants. RESULTS Of the fourteen anticonvulsants that had been employed, the most often used agents were oxcarbazepine or carbamazepine, and levetiracetam. Individuals whose seizures at the most recent visit were fully controlled (seizure-free) for 6 months or longer were more likely to have ever tried, or currently used, oxcarbazepine or carbamazepine than those with uncontrolled seizures. Thirty-nine of 69 individuals (56.5%) were seizure-free with oxcarbazepine or carbamazepine history versus 11 of 35 individuals (31.4%) who had not taken these agents (P anticonvulsants versus 12 of 42 (28.6%) not taking them (P < 0.01). Patients with seizure control for 6 months or longer were less likely to have ever tried, or to currently be taking, levetiracetam than those without control. Sixteen of 56 individuals (28.6%) were seizure-free with levetiracetam history versus 34 of 48 (70.8%) without it (P < 0.001); 14 of 43 individuals (32.6%) were seizure-free and currently taking levetiracetam versus 36 of 61 (59.0%) not taking it (P < 0.01). When topiramate was added as second-line medication, five of nine patients (55.6%) experienced decreased seizure severity, and worsening of glaucoma was not reported. CONCLUSIONS Carbamazepine and oxcarbazepine were associated with better seizure control than levetiracetam in this Sturge-Weber syndrome cohort and so may be preferred as the initial therapy. When used as adjunctive therapy, topiramate was effective in this limited analysis without a clear increased incidence of glaucoma. PMID:26997037

    The purpose of this study is to report two new cases of Usher syndrome associated with Fuchs' heterochromic uveitis (FHU), to confirm our previous observation of the association between FHU and retinitis pigmentosa (RP), and to evaluate if FHU is particularly associated with Usher syndrome. Retrospective medical record review of all new RP cases at Hadassah Medical Center between the years 2000 and 2007, review of our previously published data, and a meta-analysis of published relevant articles in peer reviewed journals. During the time frame of the study we diagnosed 58 new cases of RP, of whom one male and one female had the typical findings of FHU, and both had Usher syndrome type II. The difference in the occurrence of FHU between the 616 controls and the patients with RP was significant (p = 0.0073, Fisher's exact test). In our combined data, FHU occurred only in two types of RP; RP simplex with an incidence of 0.57%, and Usher syndrome with an incidence of 13.5%. This difference between the incidence of FHU in patients with Usher syndrome and other types of RP was significant (p Usher syndrome type II. Although infectious agents seem to play a role, the cause for this significant correlation is still unclear.

    To explore the role of traditional Chinese medicine (TCM) syndrome scores in effectiveness evaluation of clinical studies. Randomized controlled trials (RCTs) of TCM published in five journals in 2013 were retrieved, including Journal of Traditional Chinese Medicine (JTCM), Chinese Journal of Integrated Traditional and Western Medicine (CJITWM), Chinese Journal of Integrative Medicine (CJIM), Evidence-Based Complementary and Alternative Medicine (ECAM), and American Journal of Chinese Medicine (AJCM). The details of TCM syndrome scores and other relevant factors reported in articles were extracted and analyzed. Descriptive statistics and Chi-square test were used to describe general features of inclusive studies, ratios of reports on CM syndrome scores in each journal, formulated evidence, adopted evaluation rules, important degrees. The difference in the application rate of CM syndrome scores were compared in various diseases, diseases with or without CM syndrome typing, places where clinical studies were implemented, and different journals. A total of 240 RCTs were included, involving 178 published in Chinese version and 62 in English version. CM syndrome scores were used for effectiveness evaluation in 27.1% (65/240) of RCTs, of which, the highest application percentage was 35.3% (18/51) in RCTs published in CJITWM, and the lowest was 0 (0/7) in RCTs published in AJCM. There were 17 methods for grading TCM syndrome scores, of which Guideline for Clinical Research of New Chinese Herbal Medicine was most commonly used. Detailed grading standards for CM syndrome scores were reported in 46 RCTs, and CM syndrome scores were taken as primary or secondary outcomes in 6 RCTs. When describing the percentages of RCTs adopting TCM syndrome score by diseases classification, the lowest was 9.5% (2/21) in mental and behavioral disorders, and the highest was 39.1% (9/23) in endocrine, nutritional, and metabolic diseases. RCTs with TCM syndrome differentiation had a higher

    A long-standing problem of conventional chemotherapy is the lack of tumor-specific treatments. Traditional chemotherapy relies on the premise that rapidly proliferating cancer cells are more likely to be killed by a cytotoxic agent. In reality, however, cytotoxic agents have very little or no specificity, which leads to systemic toxicity, causing undesirable severe side effects. Consequently, various “molecularly targeted cancer therapies” have been developed for use in specific cancers, incl...

  20. RECENT ADVANCES IN THE 5Q- SYNDROME

    Full Text Available The 5q- syndrome is the most distinct of the myelodysplastic syndromes (MDS and patients with this disorder have a deletion of chromosome 5q [del(5q] as the sole karyotypic abnormality. Several genes mapping to the commonly deleted region of the 5q- syndrome have been implicated in disease pathogenesis in recent years. Haploinsufficiency of the ribosomal gene RPS14 has been shown to cause the erythroid defect in the 5q- syndrome. Loss of the microRNA genes miR-145 and miR-146a has been associated with the thrombocytosis observed in 5q- syndrome patients. Haploinsufficiency of CSNK1A1 leads to hematopoietic stem cell expansion in mice and may play a role in the initial clonal expansion in patients with 5q- syndrome. Moreover, a subset of patients harbor mutation of the remaining CSNK1A1 allele. Mouse models of the 5q- syndrome, which recapitulate the key features of the human disease, indicate that a p53-dependent mechanism underlies the pathophysiology of this disorder. Importantly, activation of p53 has been demonstrated in the human 5q- syndrome. Recurrent TP53 mutations have been associated with an increased risk of disease evolution and with decreased response to the drug lenalidomide in del(5q MDS patients. Potential new therapeutic agents for del(5q MDS include the translation enhancer L-leucine.

    To provide an update on recent developments on Noonan syndrome with a special focus on endocrinology, bone, and metabolism aspects. The key issues still to be resolved and the future therapeutic perspectives will be discussed. The discovery of the molecular genetic causes of Noonan syndrome and Noonan-syndrome-related disorders has permitted us to better understand the mechanisms underlying the different symptoms of these diseases and to establish genotype-phenotype correlations (in growth patterns for example). In addition to the classical clinical hallmarks of Noonan syndrome, new important aspects include decreased fertility in men, lean phenotype with increased energy expenditure and possible impact on carbohydrate metabolism/insulin sensitivity, and impaired bone health. Further clinical studies are needed to investigate the long-term impact of these findings and their possible interconnections. Finally, the understanding of the crucial role of RAS/mitogen-activated protein kinases dysregulation in the pathophysiology of Noonan syndrome allows us to devise new therapeutic approaches. Some agents are currently undergoing clinical trials in Noonan syndrome patients. On the last 10 years, our knowledge of the molecular basis and the pathophysiology of Noonan syndrome has greatly advanced allowing us to gain insight in all the aspects of this disease and to devise new specific therapeutic strategies.

    We investigated bacterial assemblages associated with corals displaying symptoms of the 'White Syndrome' (WS), a general term used for indicating the appearance of bands, spots or patches of tissue loss, which is devastating wide areas of tropical ecosystems worldwide. We collected WS-diseased (n = 15) and healthy (n = 15) corals from the natural reef (Indonesia, Indian Ocean) and from four large public aquaria. By using culture-dependent and culture-independent techniques, we found that a large fraction (73%) of the investigated WS events was associated with the presence of a high bacterial abundance and, specifically, of Vibrio spp. Vibrio harveyi, a pathogen of many marine organisms and recently involved in coral Yellow Band disease, was the most represented species, being recovered from five out of 15 diseased corals. In experimental infection assays, two V. harveyi strains, isolated from diseased corals, were inoculated on a total of 62 healthy colonies of Pocillopora damicornis. WS signs appeared in 57 corals, confirming the ability of V. harveyi strains to induce the disease. We conclude that V. harveyi is one of the coral pathogens involved in the appearance of WS. However, not all of the investigated WSs were associated to V. harveyi detection, nor to other Vibrio species (such as V. coralliilyticus), which supports the hypothesis that WS is not caused exclusively by Vibrio spp., but rather can have a multifactorial aetiology, or can represent a group of diseases caused by a variety of agents. Further investigations to identify specific virulence traits will contribute to the understanding of the role of V. harveyi in WS pathogenesis. © 2009 Society for Applied Microbiology and Blackwell Publishing Ltd.

    A good proportion of pregnant women patronize traditional birth homes in Nigeria for ante-natal care. This study aimed at determining the prevalence, risk factors, and susceptibility profile of etiologic agents of urinary tract infection among ante-natal attendees in a traditional birth home in Benin City, Nigeria. Clean-catch urine was collected from 220 pregnant women attending a traditional birth home in Benin City, Nigeria. Urine samples were processed, and microbial isolates identified using standard bacteriological procedures. A cross-sectional study design was used. The prevalence of urinary tract infection among pregnant women was 55.0%, significantly affected by parity and gestational age (Pinfection was recorded among 13(10.7%) pregnant women, and was unaffected by maternal age, parity, gravidity, gestational age, and educational status. Irrespective of trimester Escherichia coli was the most prevalent etiologic agent of urinary tract infection, followed by Staphylococcus aureus. The flouroquinolones were the most effective antibacterial agents, while Sulphamethoxazole-trimetoprim, Amoxicillin, Nalidixic acid, and Nitrofurantoin had poor activity against uropathogens isolated. The prevalence of urinary tract infection among pregnant women was 55.0% and significantly affected by gestational age and parity. The most prevalent etiologic agent observed was Escherichia coli. With the exception of the flouroquinolones, aminoglycoside, and Amoxicillin-cluvanate, the activity of other antibiotics used on uropathogens were poor. Health education of the traditional birth attendant and her clients by relevant intervention agencies is strongly advocated.

    2008-03-01

    To determine the relationship between urinary albumin excretion and features of the metabolic syndrome in women with polycystic ovary syndrome (PCOS). We retrospectively analyzed the medical records of 189 premenopausal women (mean age +/- SD, 28.9 +/- 7.7 years) with PCOS and 81 control patients (mean age +/- SD, 37.9 +/- 8.6 years) from a single endocrinology practice. Exclusion criteria were diabetes, heart disease, kidney disease, use of lipid-lowering agents, and use of antihypertensive agents (except spironolactone). The urine albumin-to-creatinine ratio (ACR) was measured in a random single-voided urine sample. Premicroalbuminuria was defined as an ACR >7 mg/g. The prevalence of ACR >7 mg/g was 31.2% in the PCOS group (N = 189) and 35.8% in the control group (N = 81). The metabolic syndrome was noted in 16.3% (27 of 166) of patients with PCOS and in 2.9% (2 of 69) of control subjects. Nine percent of patients with PCOS who had an ACR 7 mg/g had the metabolic syndrome. Patients with PCOS who had an ACR >7 mg/g had significantly higher blood pressure and alanine aminotransferase levels than did those with an ACR PCOS who had an ACR 7 mg/g, no significant difference was found in frequency of use of metformin, spironolactone, or oral contraceptives. In women with PCOS, an ACR >7 mg/g was strongly associated with the metabolic syndrome, high blood pressure, and elevated alanine aminotransferase levels. It may be useful to consider ACR >7 mg/g as an associated sign of the presence of metabolic syndrome in women with PCOS.

    Antiplatelet agents are widely prescribed for the primary and secondary prevention of cardiovascular events. A common clinical problem facing orthopaedic and trauma surgeons is how to manage patients receiving these agents who require surgery, either electively or following trauma. The dilemma is to balance the risk of increased blood loss if the antiplatelet agents are continued peri-operatively against the risk of coronary artery\\/stent thrombosis and\\/or other vascular event if the drugs are stopped. The traditional approach of stopping these medications up to two weeks before surgery appears to pose significant danger to patients and may require review. This paper covers the important aspects regarding the two most commonly prescribed antiplatelet agents, aspirin and clopidogrel.

    In this short communication, we examine how agent-based modeling has become common in land change science and is increasingly used to develop case studies for particular times and places. There is a danger that the research community is missing a prime opportunity to learn broader lessons from the use of agent-based modeling (ABM), or at the very least not sharing these lessons more widely. How do we find an appropriate balance between empirically rich, realistic models and simpler theoretically grounded models? What are appropriate and effective approaches to model evaluation in light of uncertainties not only in model parameters but also in model structure? How can we best explore hybrid model structures that enable us to better understand the dynamics of the systems under study, recognizing that no single approach is best suited to this task? Under what circumstances - in terms of model complexity, model evaluation, and model structure - can ABMs be used most effectively to lead to new insight for stakeholders? We explore these questions in the hope of helping the growing community of land change scientists using models in their research to move from 'yet another model' to doing better science with models.

    To evaluate the clinical effect of Traditional Chinese Spinal Orthopedic Manipulation (TCSOM) in treating Functional Abdominal Pain Syndrome (FAPS) in comparison with Pinaverium Bromide (Dicetel, PBD), and to assess a possible cause for FAPS. 60 cases of FAPS patients were randomly assigned to the TCSOM group and PBD group according to the random number table method. The TCSOM group was treated with thumb pressing manipulation, every other day in the first week, and once every three days in the second week, for 5 times treatments. Patients in the PBD group were instructed to take 50mg 3 times a day, consistently for 2 weeks. The symptoms of pre-treatment and post-treatment were assessed on a visual analog scale (VAS) pain score. A symptom improvement rating (SIR) was implemented in order to evaluate the effects of the treatments, and to statistically compare the two groups. The symptoms of 21 patients of the TCSOM group were resolved soon after the first spinal manipulation treatment and 4 cases were significantly improved. The VAS pain scores in the TCSOM group were significantly lower than those in the PBD group after 2 weeks treatment. According to the SIR based on VAS, the TCSOM research group included 20 cases with excellent results, 8 cases with good, and 2 cases with poor. There were no side effects in the TCSOM group after treatment. Based on VAS, the PBD research group reported 6 cases with excellent results, 8 cases with good and 16 cases with poor. All cases were statistically analyzed, revealing a significant difference (Pabdominal pain indicating that it is an effective treatment for FAPS. Copyright © 2017 The Author(s).

    2012-10-01

    Dual antiplatelet therapy is well recognized in the prevention of thrombotic complications of acute coronary syndrome and percutaneous coronary interventions. Despite clinical benefits of aspirin and clopidogrel therapy, a number of limitations curtail their efficacy: slow onset of action, variability in platelet inhibitory response and potential drug-drug interactions. Furthermore, the single platelet-activation pathway targeted by these agents allows continued platelet activation via other pathways, ensuring incomplete protection against ischemic events, thus, underscoring the need for alternate antiplatelet treatment strategies. A number of novel antiplatelet agents are currently in advance development and many have established superior effects on platelet inhibition, clinical outcomes and safety profile than clopidogrel in high-risk patients. The aim of this review is to provide an overview of the current status of P2Y12 receptor inhibition and PAR-1 antagonists in determining a future strategy for individualized antiplatelet therapy.

    Reversible posterior leucoencephalopathy syndrome (RPLS) has previously been described in patients who have renal insufficiency, eclampsia, hypertensive encephalopathy and patients receiving immunosuppressive therapy. The mechanism by which immunosuppressive agents can cause this syndrome is not clear, but it is probably related with cytotoxic effects of these agents on the vascular endothelium. We report eight patients who received cyclosporine A (CSA) after allogeneic bone marrow transplantation or as treatment for severe aplastic anemia (SSA) who developed posterior leucoencephalopathy. The most common signs and symptoms were seizures and headache. Neurological dysfunction occurred preceded by or concomitant with high blood pressure and some degree of acute renal failure in six patients. Computerized tomography studies showed low-density white matter lesions involving the posterior areas of cerebral hemispheres. Symptoms and neuroimaging abnormalities were reversible and improvement occurred in all patients when given lower doses of CSA or when the drug was withdrawn. RPLS may be considered an expression of CSA neurotoxicity.

  16. Syndromic classification of rickettsioses: an approach for clinical practice

    Directory of Open Access Journals (Sweden)

    Álvaro A. Faccini-Martínez

    2014-11-01

    Full Text Available Rickettsioses share common clinical manifestations, such as fever, malaise, exanthema, the presence or absence of an inoculation eschar, and lymphadenopathy. Some of these manifestations can be suggestive of certain species of Rickettsia infection. Nevertheless none of these manifestations are pathognomonic, and direct diagnostic methods to confirm the involved species are always required. A syndrome is a set of signs and symptoms that characterizes a disease with many etiologies or causes. This situation is applicable to rickettsioses, where different species can cause similar clinical presentations. We propose a syndromic classification for these diseases: exanthematic rickettsiosis syndrome with a low probability of inoculation eschar and rickettsiosis syndrome with a probability of inoculation eschar and their variants. In doing so, we take into account the clinical manifestations, the geographic origin, and the possible vector involved, in order to provide a guide for physicians of the most probable etiological agent.

    We report a 4-month-old female infant who developed West syndrome eleven days after administration of a histamine H1 antagonist, oxatomide, for atopic dermatitis. It has been reported that some histamine H1 antagonists induce seizures in epileptic patients. The age, the interval between oxatomide administration, and the onset of West syndrome and its clinical course were similar to two previously reported 3-month-old infants with West syndrome associated with ketotifen administration. We should be cautious in using the histamine H1 antagonists, oxatomide and ketotifen, in young infants because such agents could potentially disturb the anticonvulsive central histaminergic system.

    Full Text Available There are several infectious agents in the environment that can cause persistent infections in the host. They usually cause their symptoms shortly after first infection and later persist as silent viruses and bacteria within the body. However, these chronic infections may play an important role in the pathogenesis of schizophrenia and Tourette’s syndrome (TS. We investigated the distribution of different neurotrophic infectious agents in TS, schizophrenia and controls. A total of 93 individuals were included (schizophrenic patients, Tourette patients and controls. We evaluated antibodies against cytomegalovirus (CMV, herpes-simplex virus (HSV, Epstein-Barr virus, Toxoplasma, Mycoplasma and Chlamydia trachomatis/pneumoniae. By comparing schizophrenia and TS, we found a higher prevalence of HSV (P=0.017 and CMV (P=0.017 antibodies in schizophrenic patients. Considering the relationship between schizophrenia, TS and healthy controls, we showed that there are associations for Chlamydia trachomatis (P=0.007, HSV (P=0.027 and CMV (P=0.029. When all measured viruses, bacteria and protozoa were combined, schizophrenic patients had a higher rate of antibodies to infectious agents than TS patients (P=0.049. Tourette and schizophrenic patients show a different vulnerability to infectious agents. Schizophrenic patients were found to have a higher susceptibility to viral infections than individuals with TS. This finding might point to a modification in special immune parameters in these diseases.

  19. Agent-Centered Decision Making in Normal and Abnormal Cognition

    Directory of Open Access Journals (Sweden)

    Goldberg, Elkhonon

    2012-08-01

    Full Text Available Much of human cognition is “agent-centered,” subjective, and in that sense relative, directed at deciding, “What is best for me”. This is very different from “veridical” cognition, directed at finding an objectively correct solution inherent in the task and independent of the agent. The frontal lobes in particular are central to agent-centered decision making. Yet very little is available in the arsenal of cognitive paradigms used in the cognitive neuroscience research and in clinical neuropsychology test design to examine “agent-centered” decision making. Current paradigms and tests used to measure decision making clinically and experimentally are veridical in nature and as such miss the essence of “agent-centered” cognition. The dearth of “agent-centered” cognitive paradigms severely limits our ability to understand fully the function and dysfunction of the frontal lobes. The Cognitive Bias Task (CBT is an agent-centered paradigm designed to fill this gap. CBT has been used as a cognitive activation task in fMRI, SPECT, and EEG, as well as in studies of normal development, addiction, dementia, focal lesions, and schizophrenia. This resulted in a range of findings that eluded more traditional “veridical” paradigms and are reviewed here.

    2018-04-01

    Fructose is a natural monosaccharide broadly used in modern society. Over the past few decades, epidemiological studies have demonstrated that high fructose intake is an etiological factor of metabolic syndrome (MetS). This review highlights research advances on fructose-induced MetS, especially the underlying pathophysiological mechanism as well as pharmacotherapy by traditional Chinese medicine (TCM), using the PubMed, Web of science, China National Knowledge Infrastructure, China Science and Technology Journal and Wanfang Data. This review focuses on de novo lipogenesis (DNL) and uric acid (UA) production, two unique features of fructolysis different from glucose glycolysis. High level of DNL and UA production can result in insulin resistance, the key pathological event in developing MetS, mostly through oxidative stress and inflammation. Some other pathologies like the disturbance in brain and gut microbiota in the development of fructose-induced MetS in the past years, are also discussed. In management of MetS, TCM is an excellent representative in alternative and complementary medicine with a complete theory system and substantial herbal remedies. TCMs against MetS or MetS components, including Chinese patent medicines, TCM compound formulas, single TCM herbs and active compounds of TCM herbs, are reviewed on their effects and molecular mechanisms. TCMs with hypouricemic activity, which specially target fructose-induced MetS, are highlighted. And new technologies and strategies (such as high-throughput assay and systems biology) in this field are further discussed. In summary, fructose-induced MetS is a multifactorial disorder with the underlying complex mechanisms. Current clinical and pre-clinical evidence supports the potential of TCMs in management of MetS. Additionally, TCMs may show some advantages against complex MetS as their holistic feature through multiple target actions. However, further work is needed to confirm the effectivity and safety of TCMs

    Full Text Available Traditional Chinese medicine (TCM was formed two thousand years ago, and developed in the following centuries. TCM has a unique way of looking at health and illness. Zheng (syndrome is the basic unit and key term in TCM theory. Zheng is the pathological generalization of a certain stage in the development of disease. Treatment based on syndrome differentiation and disease differentiation of TCM is the basic principle to know and treat diseases,and a kind of special method to study diseases in TCM. In Han Dynasty (200 AD, doctor Zhang Zhongjing proposed Liujing Bianzheng (the differential diagnosis in accordance with the theory of six channels to diagnose and treat diseases in Treatise on Febrile and Miscellaneous Diseases. In other words, he divided diseases into six channels diseases based on patient’s Zhengs. Six channels diseases almost include all of the disease according to his classification standards. In addition, there are development rules in the progress of six channels diseases.Therefore, we hypothesized that combination of six channels disease and Zheng on the basic of differentiation of six channels is a new pattern of diagnosis and treatment diseases in TCM, which is beneficial to the understanding of a certain disease and makes disease treatment more convenient, fast and effective.

    with systemic corticosteroids, there is a prompt response consisting of dramatic improvement of both the dermatosis-related symptoms and skin lesions. Topical application of high potency corticosteroids or intralesional corticosteroids may be efficacious for treating localized lesions. Other first-line oral systemic agents are potassium iodide and colchicine. Second-line oral systemic agents include indomethacin, clofazimine, cyclosporine, and dapsone. The symptoms and lesions of Sweet's syndrome may resolved spontaneously, without any therapeutic intervention; however, recurrence may follow either spontaneous remission or therapy-induced clinical resolution.

    In the last decade, the treatment of higher-risk myelodysplastic syndromes (MDS) has revolved around the azanucleosides, azacitidine and decitabine, which at lower doses are postulated to work predominantly via their effects on inhibition of DNA methyltransferases and consequent DNA hypomethylation. For patients who relapse after, or do not respond to, hypomethylating agent therapy, the outcome is dismal, and new agents and approaches that have the potential to alter the natural history of these diseases are desperately needed. Allogeneic stem cell transplant is the only known potentially curative approach in MDS, but its applicability has been limited by the advanced age of patients and attendant comorbidities. There is now an increasing array of new agents under clinical investigation in MDS that aim to exploit our expanding understanding of molecular pathways that are important in the pathogenesis of MDS. This review focuses on a critical appraisal of novel agents being evaluated in higher-risk MDS that go beyond the conventional hypomethylating agent therapies approved by the US Food and Drug Administration. © 2016 by The American Society of Hematology.

    An increased risk of coronary heart disease (CHD) morbidity and mortality is associated with the metabolic syndrome, a condition characterized by the concomitant presence of several abnormalities, including abdominal obesity, dyslipidemia, hypertension, insulin resistance (with or without glucose intolerance or diabetes), microalbuminuria, prothrombotic, and proinflammatory states. Estimates of the prevalence of the metabolic syndrome indicate that this condition is now common and likely to increase dramatically over the coming decades, in parallel with greater rates of obesity and Type 2 diabetes. Risk factors for the metabolic syndrome are already present in obese children and adolescents. Thus, identifying and treating all affected individuals promptly and optimally are critical to ensure that this potentially challenging healthcare burden is minimized. Here, we review the prevalence of the metabolic syndrome, dyslipidemias, and CHD risk. Although changes in lifestyle are fundamental to reducing many of the CHD risk factors associated with the metabolic syndrome, pharmacologic interventions also play an important role. Retrospective subanalyses of the effects of statins on coronary event rates and lipid levels in patients with the metabolic syndrome included in clinical trials indicate that these agents are beneficial in correcting the extensive lipid abnormalities that are frequently present in these individuals. However, the optimal management of metabolic syndrome dyslipidemia will depend on the outcomes of future prospective clinical trials. This review examines the underlying causes and prevalence of the metabolic syndrome and its impact on CHD morbidity and mortality and discusses the role of statins in optimizing its management.

    Objective: To assess the ability of US contrast-enhanced time-intensity curves to depict the changes connected with sicca syndrome, a fairly common condition that is often associated with autoimmune disorders such as Sjogren's syndrome or other diseases. Diagnostic criteria are complex and controversial and although no single test can be considered the gold standard, salivary gland scintigraphy and biopsy are reliable diagnostic methods. Materials and methods: Sixty consecutive patients with sicca syndrome, 40 of whom had primary (n = 23) or secondary (n = 17) Sjogren's syndrome and 20 had non-Sjogren's sicca syndrome, selected according to European Community Study Group diagnostic criteria for Sjogren's syndrome and subjected to contrast-enhanced US imaging of the parotids using a second-generation contrast agent with analysis of time-intensity curves at rest and during salivary stimulation, Tc99m salivary gland scintigraphy and labial gland biopsy. Results: In the 40 Sjogren's patients, US enhancement values were significantly lower (P < 0.0001 and P < 0.00003, respectively) than in the 20 non-Sjogren's patients both at rest and during stimulation. In the 23 subjects with the primary syndrome, values during stimulation were significantly lower than in the 17 subjects with the secondary syndrome (P < 0.0006), whereas at rest differences were not significant. Contrast-enhanced US imaging allowed to discriminate Sjogren's from non-Sjogren's sicca patients with 87.5% sensitivity, 85% specificity and 86.7% accuracy and the primary from the secondary syndrome with 78.2% sensitivity, 70.5% specificity and 75% accuracy. Interestingly, in eight patients with the primary syndrome, i.e. those with the more severe gland involvement, enhancement values were lower during stimulation than at rest. Conclusion: Preliminary results indicate that contrast-enhanced US imaging can provide useful information on sicca characterisation and severity

    Traditional medical systems in low income countries remain the first line service of choice, particularly for rural communities. Although the role of traditional birth attendants (TBAs) is recognised in many primary health care systems in low income countries, other types of traditional practitioners have had less traction. We explored the role played by traditional healers in northern Ghana in managing pregnancy-related complications and examined their relevance to current initiatives to reduce maternal morbidity and mortality. A grounded theory qualitative approach was employed. Twenty focus group discussions were conducted with TBAs and 19 in-depth interviews with traditional healers with expertise in managing obstetric complications. Traditional healers are extensively consulted to manage obstetric complications within their communities. Their clientele includes families who for either reasons of access or traditional beliefs, will not use modern health care providers, or those who shop across multiple health systems. The traditional practitioners claim expertise in a range of complications that are related to witchcraft and other culturally defined syndromes; conditions for which modern health care providers are believed to lack expertise. Most healers expressed a willingness to work with the formal health services because they had unique knowledge, skills and the trust of the community. However this would require a stronger acknowledgement and integration within safe motherhood programs. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2012-02-03

    A case is described of a child with stiff baby syndrome who underwent open reduction and femoral shortening of congenital dislocated hip under general anaesthesia. Neuromuscular function was measured electromyographically and demonstrated a great degree of train of four fade (57%) after sevoflurane inhalational induction of anaesthesia. The response to suxamethonium (2 mg x kg(-1)) was normal. The neuromuscular response to volatile anaesthetic agents and suxamethonium may be abnormal in these children with stiff baby syndrome and intraoperative neuromuscular monitoring is recommended.

  12. Levetiracetam as an alternative therapy for Tourette syndrome

    2010-05-01

    Full Text Available MA Martínez-Granero, A García-Pérez, F MontañesDepartment of Pediatrics and Psychiatry, Hospital Universitario Fundación Alcorcón, Madrid, SpainAbstract: Tourette syndrome is a common childhood-onset neuropsychiatric disorder characterized by chronic tics and frequent comorbid conditions such as attention deficit disorder. Most currently used tic-suppressing drugs are frequently associated with serious adverse events. Thus, alternative therapeutic agents with more favorable side-effect profiles are being evaluated. New hypotheses and recent studies involving GABAergic system in the pathophysiology of Tourette syndrome suppose a reason for the evaluation of GABAergic drugs. Levetiracetam is a drug with an atypical GABAergic mechanism of action that might be expected to improve tics. Although trials performed to evaluate the efficacy of levetiracetam in the treatment of Tourette syndrome have provided conflicting results, it may be useful in some patients. The established safe profile of levetiracetam makes this drug an alternative for treatment if intolerance to currently used drugs appears, but additional evaluation with larger and longer duration controlled studies are necessary to assess the real efficacy in patients with Tourette syndrome.Keywords: Tourette syndrome, levetiracetam, tics, children, adolescents, GABA

    Job's syndrome (hyper IgE syndrome) is a very rare primary immunodeficiency disease that has an annual approximate incidence of less than 1/1,000,000. This manuscript aims to provide education regarding diagnosis and management strategies of this syndrome worldwide. A 6-year-old boy was seen at the clinic secondary to persistent pruritus interfering with sleep. At the age of 2 months, the patient developed diffuse eczematous and desquamating skin lesions. He was subsequently diagnosed with atopic dermatitis and managed conservatively. From 2 months to 7 years of age, intermittent exacerbations of dermatitis persisted despite an aggressive treatment regimen. The serum IgE level increased exponentially over a period of 7 years, with a peak value of 57,400 IU/ml. Molecular genetic testing revealed a dominant negative mutation within the SH2 domain of the Signal Transducer and Activator of Transcription (STAT3) gene. The patient was subsequently diagnosed with Job's syndrome. Management included proper skin care, prophylactic antibiotics, immunomodulating agents, and psychotherapy. Job's syndrome can often go unrecognized and masquerade as atopic dermatitis. Therefore, genetic testing for this condition should be obtained in all patients with treatment-refractory AD. Additionally, psychotherapy can be a successful management strategy for the grating psychological impact that can be imposed on children with excessive pruritus.

    The iridocorneal endothelial (ICE) syndrome is a rare ocular disorder that includes a group of conditions characterized by structural and proliferative abnormalities of the corneal endothelium, the anterior chamber angle, and the iris. Common clinical features include corneal edema, secondary glaucoma, iris atrophy, and pupillary anomalies, ranging from distortion to polycoria. The main subtypes of this syndrome are the progressive iris atrophy, the Cogan-Reese syndrome, and the Chandler syndrome. ICE syndrome is usually diagnosed in women in the adult age. Clinical history and complete eye examination including tonometry and gonioscopy are necessary to reach a diagnosis. Imaging techniques, such as in vivo confocal microscopy and ultrasound biomicroscopy, are used to confirm the diagnosis by revealing the presence of “ICE-cells” on the corneal endothelium and the structural changes of the anterior chamber angle. An early diagnosis is helpful to better manage the most challenging complications such as secondary glaucoma and corneal edema. Treatment of ICE-related glaucoma often requires glaucoma filtering surgery with antifibrotic agents and the use of glaucoma drainage implants should be considered early in the management of these patients. Visual impairment and pain associated with corneal edema can be successfully managed with endothelial keratoplasty. PMID:26451377

  15. Phytochemicals and the breakthrough of traditional herbs in the management of sexual dysfunctions.

    Traditional herbs have been a revolutionary breakthrough in the management of erectile dysfunction and have become known world-wide as an 'instant' treatment. The modern view of the management of erectile dysfunction subscribes to a single etiology, i.e. the mechanism of erection. A large number of pharmacological agents are orally consumed and vasoactive agents inserted intraurethrally or injected intrapenially to regain good erection. Modern phytochemicals have developed from traditional herbs. Phytochemicals focus their mechanism of healing action to the root cause, i.e. the inability to control the proper function of the whole body system. Hence phytochemicals manage erectile dysfunction in the frame of sexual dysfunction as a whole entity. Protodioscin is a phytochemical agent derived from Tribulus terrestris L plant, which has been clinically proven to improve sexual desire and enhance erection via the conversion of protodioscine to DHEA (De-Hydro-Epi-Androsterone). Preliminary observations suggest that Tribulus terrestris L grown on different soils does not consistently produce the active component Protodioscin. Further photochemical studies of many other herbal plants are needed to explain the inconsistent results found with other herbal plants, such as in diversities of Ginseng, Eurycoma longifolia, Pimpinella pruacen, Muara puama, Ginkgo biloba, Yohimbe etc.

    Gardeniae Fructus, which is widely used in health foods and clinical medicines, is a type of edible food and medicine. Dictionary of traditional Chinese medicine prescriptions provides good materials for prescription analysis and the R&D of traditional Chinese medicines. The composition regularity of formulae containing Gardeniae Fructus in dictionary of traditional Chinese medicine prescriptions was analyzed on the basis of the traditional Chinese medicine inheritance support system(TCMISS), in order to provide reference for clinical application and the R&D of new drugs. TCMISS was applied to establish a database of prescriptions containing Gardeniae Fructus. The software's frequency statistics and association rules and other date mining technologies were adopted to analyze commonly used drugs, combination rules and core combined formulae containing Gardeniae Fructus. Totally 3 523 prescriptions were included in this study and involved 1 725 Chinese herbs. With a support degree of 352(10%) and confidence coefficient of 90%, 57 most commonly used drug combinations were screened. Drugs adopted in core combinations were relatively concentrated and selected according to definite composition methods. They were used to mainly treat 18 diseases. Gardeniae Fructus have often been combined with herbs for heat-clearing and detoxification, expelling pathogenic wind, relieving exterior syndrome, invigorating the circulation of blood and gas and promoting blood circulation for removing blood stasis to mainly treat jaundice, typhoid, headache and other syndromes.

    Cushing’s syndrome is a rare disorder resulting from prolonged exposure to excess glucocorticoids. Early diagnosis and treatment of Cushing’s syndrome is associated with a decrease in morbidity and mortality. Clinical presentation can be highly variable, and establishing the diagnosis can often be difficult. Surgery (resection of the pituitary or ectopic source of adrenocorticotropic hormone, or unilateral or bilateral adrenalectomy) remains the optimal treatment in all forms of Cushing’s syndrome, but may not always lead to remission. Medical therapy (steroidogenesis inhibitors, agents that decrease adrenocorticotropic hormone levels or glucocorticoid receptor antagonists) and pituitary radiotherapy may be needed as an adjunct. A multidisciplinary approach, long-term follow-up, and treatment modalities customized to each individual are essential for optimal control of hypercortisolemia and management of comorbidities.

    Matrixmetalloproteinase inhibitors have been developed as anti-cancer agents. Their usage in pancreatic cancer and other such malignancies is under trial at present. An interesting undesired-effect of one of these agents is contracture of the hand. Ehler-Danlos syndrome is an inherited group of diseases with varying types. At present there is no known treatment or prevention for the complications associated with this inherited condition. Sometimes it is the adverse events of a drug, which provides an insight into its efficacy for another indication. It is hereby being hypothesized that the matrixmetalloproteinase inhibitors especially marimastat may be an effective drug for treatment of Ehler-Danlos syndrome and/or prevention of its major complications.

    Lynch syndrome is the most common hereditary cancer syndrome, the most common cause of heritable colorectal cancer, and the only known heritable cause of endometrial cancer. Other cancers associated with Lynch syndrome include cancers of the ovary, stomach, urothelial tract, and small bowel, and less frequently, cancers of the brain, biliary tract, pancreas, and prostate. The oncogenic tendency of Lynch syndrome stems from a set of genomic alterations of mismatch repair proteins. Defunct mismatch repair proteins cause unusually high instability of regions of the genome called microsatellites. Over time, the accumulation of mutations in microsatellites and elsewhere in the genome can affect the production of important cellular proteins, spurring tumorigenesis. Universal testing of colorectal tumors for microsatellite instability (MSI) is now recommended to (a) prevent cases of Lynch syndrome being missed owing to the use of clinical criteria alone, (b) reduce morbidity and mortality among the relatives of affected individuals, and (c) guide management decisions. Organ-specific cancer risks and associated screening paradigms vary according to the sex of the affected individual and the type of germline DNA alteration causing the MSI. Furthermore, Lynch syndrome-associated cancers have different pathologic, radiologic, and clinical features compared with their sporadic counterparts. Most notably, Lynch syndrome-associated tumors tend to be more indolent than non-Lynch syndrome-associated neoplasms and thus may respond differently to traditional chemotherapy regimens. The high MSI in cases of colorectal cancer reflects a difference in the biologic features of the tumor, possibly with a unique susceptibility to immunotherapy. © RSNA, 2018.

    Full Text Available Chinese medicine syndrome (CMS, “ZHENG” in Chinese is an understanding of the regularity of disease occurrence and development as well as a certain stage of a comprehensive response of patients with body condition. However, because of the complexity of CMS and the limitation of present investigation method, the research for deciphering the scientific basis and systematic features of CMS is difficult to go further. Metabolomics enables mapping of early biochemical changes in disease and hence provides an opportunity to develop predictive biomarkers. Moreover, its method and design resemble those of traditional Chinese medicine (TCM which focuses on human disease via the integrity of close relationship between body and syndromes. In the systemic context, metabolomics has a convergence with TCM syndrome; therefore it could provide useful tools for exploring essence of CMS disease, facilitating personalized TCM, and will help to in-depth understand CMS. The integration of the metabolomics and CMS aspects will give promise to bridge the gap between Chinese and Western medicine and help catch the traditional features of CMS. In this paper, particular attention will be paid to the past successes in applications of robust metabolomic approaches to contribute to low-molecular-weight metabolites (biomarkers discovery in CMS research and development.

    In the clinical practice, Professor Jiang Liangduo, a national senior Chinese medicine doctor, has created the theory of "sanjiao meridian stasis" from the theory of meridian dialectics and from the overall state. In this paper, the traditional Chinese medicine and Western medicine clinical characteristics of sanjiao meridian stasis theory which is often used by Professor Jiang Liangduo in the treatment of out-patient syndrome differentiation, were first studied and summarized to investigate its inherent regularity. First, the source of data and research methods were introduced, and then the Traditional Chinese Medicine Inheritance Support System was used with the method of data mining to retrospectively analyze the disease characteristics of Chinese and Western medicine in 279 patients with sanjiao meridian stasis diagnosed by Professor Jiang in 2014. Then the following main conclusions were made after research: sanjiao meridian stasis was more common in women as well as young and middle-aged population. Often manifested by prolonged treatment course, red tongue with yellowishfur, with good correlation between modern Western medicine diagnosis and TCM differentiation syndrome. The symptoms of sanjiao meridian stasis syndrome are mostly of heat syndromes, and middle-aged patients are the most common patients with stasis and stasis of sanjiao. Related information of Western medicine diagnosis can help to diagnose the "sanjiao meridian stasis". Copyright© by the Chinese Pharmaceutical Association.

    Syndromic surveillance complements traditional public health surveillance by collecting and analysing health indicators in near real time. The rationale of syndromic surveillance is that it may detect health threats faster than traditional surveillance systems permitting more timely, and hence potentially more effective public health action. The effectiveness of syndromic surveillance largely relies on the methods used to detect aberrations. Very few studies have evaluated the performance of syndromic surveillance systems and consequently little is known about the types of events that such systems can and cannot detect. We introduce a framework for the evaluation of syndromic surveillance systems that can be used in any setting based upon the use of simulated scenarios. For a range of scenarios this allows the time and probability of detection to be determined and uncertainty is fully incorporated. In addition, we demonstrate how such a framework can model the benefits of increases in the number of centres reporting syndromic data and also determine the minimum size of outbreaks that can or cannot be detected. Here, we demonstrate its utility using simulations of national influenza outbreaks and localised outbreaks of cryptosporidiosis. Influenza outbreaks are consistently detected with larger outbreaks being detected in a more timely manner. Small cryptosporidiosis outbreaks (framework constitutes a useful tool for public health emergency preparedness in multiple settings. The proposed framework allows the exhaustive evaluation of any syndromic surveillance system and constitutes a useful tool for emergency preparedness and response.

    The reliability and validity of traditional taxonomies are limited by arbitrary boundaries between psychopathology and normality, often unclear boundaries between disorders, frequent disorder co-occurrence, heterogeneity within disorders, and diagnostic instability. These taxonomies went beyond evidence available on the structure of psychopathology and were shaped by a variety of other considerations, which may explain the aforementioned shortcomings. The Hierarchical Taxonomy Of Psychopathology (HiTOP) model has emerged as a research effort to address these problems. It constructs psychopathological syndromes and their components/subtypes based on the observed covariation of symptoms, grouping related symptoms together and thus reducing heterogeneity. It also combines co-occurring syndromes into spectra, thereby mapping out comorbidity. Moreover, it characterizes these phenomena dimensionally, which addresses boundary problems and diagnostic instability. Here, we review the development of the HiTOP and the relevant evidence. The new classification already covers most forms of psychopathology. Dimensional measures have been developed to assess many of the identified components, syndromes, and spectra. Several domains of this model are ready for clinical and research applications. The HiTOP promises to improve research and clinical practice by addressing the aforementioned shortcomings of traditional nosologies. It also provides an effective way to summarize and convey information on risk factors, etiology, pathophysiology, phenomenology, illness course, and treatment response. This can greatly improve the utility of the diagnosis of mental disorders. The new classification remains a work in progress. However, it is developing rapidly and is poised to advance mental health research and care significantly as the relevant science matures.

    Trichloroethylene is commonly used as an industrial solvent and degreasing agent. The clinical features of acute and chronic intoxication with trichloroethylene are well-known and have been described in many reports, but hypersensitivity syndrome caused by trichloroethylene is rarely encountered. For managing patients with trichloroethylene hypersensitivity syndrome, avoiding trichloroethylene and initiating glucocorticoid have been generally accepted. Generally, glucocorticoid had been tapered as trichloroethylene hypersensitivity syndrome had ameliorated. However, we encountered a typical case of trichloroethylene hypersensitivity syndrome refractory to high dose glucocorticoid treatment. A 54-year-old Korean man developed jaundice, fever, red sore eyes, and generalized erythematous maculopapular rashes. A detailed history revealed occupational exposure to trichloroethylene. After starting intravenous methylprednisolone, his clinical condition improved remarkably, but we could not reduce prednisolone because his liver enzyme and total bilirubin began to rise within 2 days after reducing prednisolone under 60 mg/day. We recommended an extended admission for complete recovery, but the patient decided to leave the hospital against medical advice. The patient visited the emergency department due to pneumonia and developed asystole, which did not respond to resuscitation.

    Full Text Available Russell P Saneto1, Gail D Anderson21Division of Pediatric Neurology, Seattle Children’s Hospital/University of Washington, Seattle, Washington, USA; 2Department of Pharmacy, University of Washington, Seattle, Washington, USAAbstract: Lennox-Gaustaut syndrome is an electroclinical epilepsy syndrome characterized by the triad of electroencephalogram showing diffuse slow spike-and-wave discharges and paroxysmal fast activity, multiple intractable seizure types, and cognitive impairment. The intractability to seizure medications and cognitive impairment gives rise to eventual institutionalized patient care. Only a small subset of seizure medications has been shown to be helpful in seizure control. Most patients take up to 3 medications at high therapeutic dosing and are susceptible to medication-induced side effects. The lack of medication efficacy in seizure control has led one meta-analysis to conclude that there is no single medication that is highly efficacious in controlling seizures in this syndrome. On this background, a new and structurally novel seizure medication, rufinamide, has been found to be beneficial in the treatment of seizures in this syndrome. In a multicenter, double-blinded, randomized, placebo-controlled study, rufinamide was found to reduce seizures by over 30%. More importantly, it reduced the frequency of the seizure type that induces most of the morbidity of this syndrome, the drop seizure, by over 40%. There were few side effects, the medication was well tolerated, and in the open labeled extension study, tolerance was not found. In this review, we describe the main electroclinical features of Lennox-Gaustaut syndrome and summarize the few controlled studies that have contributed to its rational treatment. Currently, there is no single agent or combination of agents that effectively treat the multiple seizure types and co-morbidities in this syndrome. Our focus will be on the role of the new medication rufinamide in

  10. Secure Mobile Agent from Leakage-Resilient Proxy Signatures

    Full Text Available A mobile agent can sign a message in a remote server on behalf of a customer without exposing its secret key; it can be used not only to search for special products or services, but also to make a contract with a remote server. Hence a mobile agent system can be used for electronic commerce as an important key technology. In order to realize such a system, Lee et al. showed that a secure mobile agent can be constructed using proxy signatures. Intuitively, a proxy signature permits an entity (delegator to delegate its signing right to another entity (proxy to sign some specified messages on behalf of the delegator. However, the proxy signatures are often used in scenarios where the signing is done in an insecure environment, for example, the remote server of a mobile agent system. In such setting, an adversary could launch side-channel attacks to exploit some leakage information about the proxy key or even other secret states. The proxy signatures which are secure in the traditional security models obviously cannot provide such security. Based on this consideration, in this paper, we design a leakage-resilient proxy signature scheme for the secure mobile agent systems.

  11. Improved Diagnoses and Quantification of Fusarium virguliforme, Causal Agent of Soybean Sudden Death Syndrome.

    2015-03-01

    Fusarium virguliforme (syn. F. solani f. sp. glycines) is the primary causal pathogen responsible for soybean sudden death syndrome (SDS) in North America. Diagnosis of SDS is difficult because symptoms can be inconsistent or similar to several soybean diseases and disorders. Additionally, quantification and identification of F. virguliforme by traditional dilution plating of soil or ground plant tissue is problematic due to the slow growth rate and plastic morphology of F. virguliforme. Although several real-time quantitative polymerase chain reaction (qPCR)-based assays have been developed for F. virguliforme, the performance of those assays does not allow for accurate quantification of F. virguliforme due to the reclassification of the F. solani species complex. In this study, we developed a TaqMan qPCR assay based on the ribosomal DNA (rDNA) intergenic spacer (IGS) region of F. virguliforme. Specificity of the assay was demonstrated by challenging it with genomic DNA of closely related Fusarium spp. and commonly encountered soilborne fungal pathogens. The detection limit of this assay was determined to be 100 fg of pure F. virguliforme genomic DNA or 100 macroconidia in 0.5 g of soil. An exogenous control was multiplexed with the assay to evaluate for PCR inhibition. Target locus copy number variation had minimal impact, with a range of rDNA copy number from 138 to 233 copies per haploid genome, resulting in a minor variation of up to 0.76 cycle threshold values between strains. The qPCR assay is transferable across platforms, as validated on the primary real-time PCR platform used in the Northcentral region of the National Plant Diagnostic Network. A conventional PCR assay for F. virguliforme detection was also developed and validated for use in situations where qPCR is not possible.

    Full Text Available Based on the basic concepts of agent and fuzzy T-S model, an agent based fuzzy T-S multi-model (ABFT-SMM system is proposed in this paper. Different from the traditional method, the parameters and the membership value of the agent can be adjusted along with the process. In this system, each agent can be described as a dynamic equation, which can be seen as the local part of the multi-model, and it can execute the task alone or collaborate with other agents to accomplish a fixed goal. It is proved in this paper that the agent based fuzzy T-S multi-model system can approximate any linear or nonlinear system at arbitrary accuracy. The applications to the benchmark problem of chaotic time series prediction, water heater system and waste heat utilizing process illustrate the viability and the efficiency of the mentioned approach. At the same time, the method can be easily used to a number of engineering fields, including identification, nonlinear control, fault diagnostics and performance analysis.

    Chinese medicine prescriptions are a type of medical documents written by doctors after they understand the patients' conditions for syndrome differentiation. Chinese medicine prescriptions are also the basis for pharmacy personnel to dispense medicines and guide patients to use drugs. It has the legal, technical and economic significances. Chinese medicine prescriptions contain such information of names, quantity and usage. Whether the names of drugs in Chinese medicine prescriptions are standardized or not is directly related to the safety and efficacy of the drugs. At present, nonstandard clinical prescriptions are frequently seen. With "Chinese medicine prescription", "names of drug in Chinese medicine prescription" and "standards of Chinese medicine prescription" as key words, the author searched CNKI, Wanfang and other databases, and consulted nearly 100 literatures, so as to summarize current names of drugs in traditional Chinese medicine prescription, analyze the reasons, and give suggestions, in the expectation of standardizing the names of drugs used in traditional Chinese medicine prescriptions.

  14. Rediscovering the Economics of Keynes in an Agent-Based Computational Setting

    DEFF Research Database (Denmark)

    Bruun, Charlotte

    The aim of this paper is to use agent-based computational economics to explore the economic thinking of Keynes. Taking his starting point at the macroeconomic level, Keynes argued that economic systems are characterized by fundamental uncertainty - an uncertainty that makes rule-based behaviour...... and reliance on monetary magnitudes more optimal to the economic agent than profit- and utility optimazation in the traditional sense. Unfortunately more systematic studies of the properties of such a system was not possible at the time of Keynes. The system envisioned by Keynes holds a lot of properties...... in commen with what we today call complex dynamic systems, and today we may aply the method of agent-based computational economics to the ideas of Keynes. The presented agent-based Keynesian model demonstrate, as argued by Keynes, that the economy can selforganize without relying on price movement...

    Traditional Chinese medicines have been widely investigated for the treatment of Alzheimer's disease (AD) because none of the current therapies-either the cholinesterase inhibitors or antagonist of N-methyl-d-aspartate receptors-has profound effects on halting the progression of AD. In recent years, scientists have isolated many active compounds from herbs, which can alleviate dementia and neurodegenerative syndrome with fewer side effects than conventional drugs and, thus, are regarded as promising drug candidates for AD therapy. In this review, we summarize the latest research progress on six herbs for AD therapy-Huperzia serrata, Amaryllidaceae family, Ginkgo biloba, Uncaria rhynchophylla, Polygala tenuifolia, and Salvia officinalis-and focus on the analysis of their active components and possible mechanisms of pharmacological actions on AD.

    2016-01-01

    Traditional magnetic resonance imaging (MRI) contrast agents mainly include superparamagnetic (SPM) iron oxide nanoparticle as T 2 contrast agent for liver and paramagnetic Gd (III)-chelate as T 1 contrast agent for all organs. In this work, weak ferromagnetic kale-like and SPM cabbage-like Ni 3 S 2 @Ni hybrid architectures were synthesized and evaluated as potential T 1 MRI contrast agents. Their relatively small r 2 /r 1 ratios of 2.59 and 2.38, and high r 1 values of 11.27 and 4.89 mmol −1 L s −1 (for the kale-like and cabbage-like Ni 3 S 2 @Ni, respectively) will shed some light on the development of new-type MRI contrast agents.

    Full Text Available AIM: A potential link between infectious agents and atherosclerosis has been suggested. Data obtained from several seroepidemiological studies have suggested that infection with Chlamydophila pneumoniae, Helicobacter pylori, and Cytomegalovirus can initiate or maintain the atherosclerotic process. Aim of this study is to evaluate the probable relationship between serum titers of some various infectious agents and the development of acute coronary syndrome and to investigate the relationship between these infectious agents and other risk factors of acute coronary syndrome (smoking, hypertension, dyslipidemia, diabetes, and family history of CVD. METHOD: This is a hospital based case- control study was conducted on two groups: patients group included 86 patients, cases were collected from patients admitted to Cardiac Care Unit (CCU of Cleopatra hospital, and Ain Shams University hospital with acute myocardial infarction between January 2010 and June 2010 and control group included 86 apparently healthy individuals. A questionnaire was designed to determine conventional coronary artery risk factors. The sero-prevalence of Chlamydia pneumoniae (C. pneumoniae, Cytomegalovirus and Helicobacter pylori (H. pylori IgG antibodies were evaluated using quantitative enzyme-linked immunosorbent assay (ELISA. RESULTS: The results showed that there was an increased level of serum IgG antibodies of C. pneumoniae, Cytomegalovirus and Helicobacter pylori among patients with acute coronary syndrome compared to control subjects CONCLUSION: C. pneumoniae, Cytomegalovirus and Helicobacter pylori were expected to be predictors for the development of coronary artery disease, as there was significant elevation of the serum level of IgG antibodies against them.

    Whole cell extracts from human lymphoid cell lines can perform in vitro DNA repair synthesis in plasmids damaged by agents including UV or cis-diamminedichloroplatinum(II) (cis-DDP). Extracts from xeroderma pigmentosum (XP) cells are defective in repair synthesis. We have now studied in vitro DNA repair synthesis using extracts from lymphoblastoid cell lines representing four human hereditary syndromes with increased sensitivity to DNA-damaging agents. Extracts of cell lines from individuals with the sunlight-sensitive disorders dysplastic nevus syndrome or Cockayne's syndrome (complementation groups A and B) showed normal DNA repair synthesis in plasmids with UV photoproducts. This is consistent with in vivo measurements of the overall DNA repair capacity in such cell lines. A number of extracts were prepared from two cell lines representing the variant form of XP (XP-V). Half of the extracts prepared showed normal levels of in vitro DNA repair synthesis in plasmids containing UV lesions, but the remainder of the extracts from the same cell lines showed deficient repair synthesis, suggesting the possibility of an unusually labile excision repair protein in XP-V. Fanconi's anemia (FA) cells show cellular hypersensitivity to cross-linking agents including cis-DDP. Extracts from cell lines belonging to two different complementation groups of FA showed normal DNA repair synthesis in plasmids containing cis-DDP or UV adducts. Thus, there does not appear to be an overall excision repair defect in FA, but the data do not exclude a defect in the repair of interstrand DNA cross-links

    Kearns-Sayre syndrome (KSS) is a rare mitochondrial DNA deletion syndrome defined as the presence of ophthalmoplegia, pigmentary retinopathy, onset less than age 20 years, and one of the following: cardiac conduction defects, cerebellar syndrome, or cerebrospinal fluid protein above 100 mg/dl. KSS may affect many organ systems causing endocrinopathies, encephalomyopathy, sensorineural hearing loss, and renal tubulopathy. Clinical presentation at diagnosis is quite heterogeneous and, usually, few organs are affected with progression to generalized disease early in adulthood. We present the case of a boy with KSS presenting at the age of 5 years with myopathy, Addison's disease, primary hypoparathyroidism, and Fanconi syndrome. The proper replacement treatment along with the administration of mitochondrial metabolism-improving agents had a brief ameliorating effect, but gradual severe multisystemic deterioration was inevitable over the next 5 years. This report highlights the fact that in case of simultaneous presentation of polyendocrinopathies and renal disease early in childhood, KSS should be considered.

    Despite the considerable advancements in the development of antimicrobial agents, incidents of epidemics due to multi drug resistance in microorganisms have created a massive hazard to mankind. Due to increased resistance against conventional antibiotics, researchers and pharmaceutical industries are more concerned about novel therapeutic agents for the prevention of bacterial infections. Enormous wealth of traditional system of medicine gains importance in health therapies over again. With ancient credentials of potent medicinal plants, various herbal remedies came forward for the management of bacterial infections. The Ayurvedic approach facilitates the development of new therapeutic agents due to structural and functional diversity among phytochemicals. The abundance and diversity is responsible for the characterization of new lead structures from medicinal plants. Industrial interest has increased due to recent research advancements viz. synergistic and high-throughput screening approach for the evaluation of vast variety of phytochemicals. The review certainly emphasizes on the traditional medicines as alternatives to conventional chemotherapeutic drugs. The review briefly describes mode of action of various antibiotics and resistance mechanisms. This review focuses on the chemical diversity and various mechanisms of action of phytochemicals against bacterial pathogens.

    Wolfram syndrome 1 is a very rare monogenic disease resulting in a complex of disorders including diabetes mellitus. Up to now, insulin has been used to treat these patients. Some of the monogenic forms of diabetes respond preferentially to sulphonylurea preparations. The aim of the current study was to elucidate whether exenatide, a GLP-1 receptor agonist, and glipizide, a sulphonylurea, are effective in a mouse model of Wolfram syndrome 1. Wolframin-deficient mice were used to test the effect of insulin secretagogues. Wolframin-deficient mice had nearly normal fasting glucose levels but developed hyperglycaemia after glucose challenge. Exenatide in a dose of 10 μg/kg lowered the blood glucose level in both wild-type and wolframin-deficient mice when administered during a nonfasted state and during the intraperitoneal glucose tolerance test. Glipizide (0.6 or 2 mg/kg) was not able to reduce the glucose level in wolframin-deficient animals. In contrast to other groups, wolframin-deficient mice had a lower insulin-to-glucose ratio during the intraperitoneal glucose tolerance test, indicating impaired insulin secretion. Exenatide increased the insulin-to-glucose ratio irrespective of genotype, demonstrating the ability to correct the impaired insulin secretion caused by wolframin deficiency. We conclude that GLP-1 agonists may have potential in the treatment of Wolfram syndrome-related diabetes.

    Objective: Because of the limited of 99 Tc m -diethyl iminodiacetic acid ( 99 Tc m -EHIDA) hepatobiliary scintigraphy in the diagnosis of severe cholestatic infant hepatitis syndrome, trial use 99 Tc m -methoxy isobutyl isonitrile ( 99 Tc m -MIBI) as a new hepatobiliary scintigraphy imaging agent to understand its applied basis and primary evaluate value in diagnosis of severe cholestatic infant hepatitis syndrome. Methods: constructed choledochal atresia animal model and investigated the application basis of 99 Tc m -MIBI hepatobiliary scintigraphy. Twenty-seven children patients of severe cholestatic who finally confirmed infant hepatitis syndrome were underwent firstly 99 Tc m -EHIDIA hepatobiliary scintigraphy. After 24 h delay imaging next day, 99 Tc m -MIBI hepatobiliary scintigraphy was underwent after 1 h. Two imaging agents of value in the diagnosis of severe cholestatic infant hepatitis syndrome were compared. Results: It was proved that 99 Tc m -MIBI was surely excreted by hepatobiliary and had no intestinal autocrine phenomenon in animal test. So 99 Tc m -MIBI can be used to undergo hepatobiliary scintigraphy. The sensitivity of 99 Tc m -MIBI hepatobiliary scintigraphy in the diagnosis of severe cholestatic infant hepatitis syndrome was 100% in our primary clinical study. Its sensitivity was higher than which of 99 Tc m -EHIDA hepatobiliary scintigraphy (66.67%) by far. Conclusion: With regard to those children patients who suspected highly severe cholestatic infant hepatitis syndrome in clinical, the sensitivity of 99 Tc m -MIBI hepatobiliary scintigraphy is obviously superior to conventional 99 Tc m -EHIDA hepatobiliary scintigraphy.

    Full Text Available Two types of neglect are described: hemispatial and motivational neglect syndromes. Neglect syndrome is a neurophysiologic condition characterized by a malfunction in one hemisphere of the brain, resulting in contralateral hemispatial neglect in the absence of sensory loss and the right parietal lobe lesion being the most common anatomical site leading to it. In motivational neglect, the less emotional input is considered from the neglected side where anterior cingulate cortex harbors the most frequent lesions. Nevertheless, there are reports of injuries in the corpus callosum (CC causing hemispatial neglect syndrome, particularly located in the splenium. It is essential for a neurosurgeon to recognize this clinical syndrome as it can be either a primary manifestation of neurosurgical pathology (tumor, vascular lesion or as a postoperative iatrogenic clinical finding. The authors report a postoperative hemispatial neglect syndrome after a falcotentorial meningioma removal that recovered 10 months after surgery and performs a clinical, anatomical, and histological review centered in CC as key agent in neglect syndrome.

    2015-03-01

    Metabolic syndrome and its complications continue to rise in prevalence and show no signs of abating in the immediate future. Therefore, the search for effective treatments is a high priority in biomedical research. Products derived from botanicals have a time-honored history of use in the treatment of metabolic diseases including type 2 diabetes. Trigonella foenum-graecum, commonly known as fenugreek, is an annual herbaceous plant that has been a staple of traditional herbal medicine in many cultures. Although fenugreek has been studied in both clinical and basic research settings, questions remain about its efficacy and biologic mechanisms of action. Diosgenin, 4-hydroxyisoleucine, and the fiber component of the plant are the most intensively studied bioactive constituents present in fenugreek. These compounds have been demonstrated to exert beneficial effects on several physiologic markers including glucose tolerance, inflammation, insulin action, liver function, blood lipids, and cardiovascular health. Although insights into the molecular mechanisms underlying the favorable effects of fenugreek have been gained, we still do not have definitive evidence establishing its role as a therapeutic agent in metabolic disease. This review aims to summarize the currently available evidence on the physiologic effects of the 3 best-characterized bioactive compounds of fenugreek, with particular emphasis on biologic mechanisms of action relevant in the context of metabolic syndrome. © 2015 American Society for Nutrition.

    This review covers recent discoveries of phytoconstituents, herbal extracts and some semi-synthetic compounds for treating metabolic syndrome with AMPK activation as one of their mechanisms of action. Recent researches have demonstrated AMPK activation to ameliorate multiple components of metabolic syndrome by regulating a balance between anabolic and catabolic cellular reactions. The review attempts to delineate the AMPK activation by natural agents from the perspective of its functional consequences on enzymes, transcription factors and signaling molecules and also on other potential factors contributing in the amelioration of metabolic syndrome.

    Full Text Available Purpose Chronic pelvic pain syndrome (CPPS is treated by use of various protocols. We compared tamsulosin monotherapy with tamsulosin in combination with antibiotics or anti-inflammatory agents and evaluated the efficacy of these treatments in patients with CPPS. Methods Patients (n=107 who were younger than 55 years and diagnosed with CPPS were randomly assigned to treatment with tamsulosin at 0.2 mg (group A, tamsulosin at 0.2 mg plus anti-inflammatory drugs (group B or tamsulosin at 0.2 mg plus antibiotics (group C daily. We applied the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI and the International Prostate Symptom Score (IPSS to evaluate 100 patients who were treated for 12 weeks (7 withdrew. Scores of the three groups were compared by analysis of variance and we also evaluated subscores, which included pain, voiding and quality of life (QoL. Results All three groups showed statistically significant decreases in NIH-CPSI score, IPSS and subscore scores (P<0.05. There were no statistically significant differences between the groups except for the QoL domain of the IPSS (group A vs. C; P<0.01. Conclusions Tamsulosin monotherapy for 12 weeks was effective for treating patients with CPPS, compared with combination therapy with antibiotics or anti-inflammatory drugs.

    Full Text Available Abstract Dual antiplatelet therapy is a well-established treatment in patients with non-ST elevation acute coronary syndrome (NSTE-ACS, with class I of recommendation (level of evidence A in current national and international guidelines. Nonetheless, these guidelines are not precise or consensual regarding the best time to start the second antiplatelet agent. The evidences are conflicting, and after more than a decade using clopidogrel in this scenario, benefits from the routine pretreatment, i.e. without knowing the coronary anatomy, with dual antiplatelet therapy remain uncertain. The recommendation for the upfront treatment with clopidogrel in NSTE-ACS is based on the reduction of non-fatal events in studies that used the conservative strategy with eventual invasive stratification, after many days of the acute event. This approach is different from the current management of these patients, considering the established benefits from the early invasive strategy, especially in moderate to high-risk patients. The only randomized study to date that specifically tested the pretreatment in NSTE-ACS in the context of early invasive strategy, used prasugrel, and it did not show any benefit in reducing ischemic events with pretreatment. On the contrary, its administration increased the risk of bleeding events. This study has brought the pretreatment again into discussion, and led to changes in recent guidelines of the American and European cardiology societies. In this paper, the authors review the main evidence of the pretreatment with dual antiplatelet therapy in NSTE-ACS.

    Inositol acts as a second messenger in insulin signaling pathway Literature data suggest inositol deficiency in insulin-resistant women with the polycystic ovary syndrome. Supplementation of myo-inisitol decreases insulin resistance as it works as an insulin sensitizing agent. The positive role of myo-inositol in the treatment of polycystic ovary syndrome has been of increased evidence recently The present review presents the effects of myo-inositol on the ovarian, hormonal and metabolic parameters in women with PCOS.

  14. A non-traditional model of the metabolic syndrome: the adaptive significance of insulin resistance in fasting-adapted seals

    Full Text Available Insulin resistance in modern society is perceived as a pathological consequence of excess energy consumption and reduced physical activity. Its presence in relation to the development of cardiovascular risk factors has been termed the metabolic syndrome, which produces increased mortality and morbidity and which is rapidly increasing in human populations. Ironically, insulin resistance likely evolved to assist animals during food shortages by increasing the availability of endogenous lipid for catabolism while protecting protein from use in gluconeogenesis and eventual oxidation. Some species that incorporate fasting as a predictable component of their life history demonstrate physiological traits similar to the metabolic syndrome during prolonged fasts. One such species is the northern elephant seal (Mirounga angustirostris, which fasts from food and water for periods of up to three months. During this time, ~90% of the seals metabolic demands are met through fat oxidation and circulating non-esterified fatty acids are high (0.7-3.2 mM. All life history stages of elephant seal studied to date demonstrate insulin resistance and fasting hyperglycemia as well as variations in hormones and adipocytokines that reflect the metabolic syndrome to some degree. Elephant seals demonstrate some intriguing adaptations with the potential for medical advancement; for example, ketosis is negligible despite significant and prolonged fatty acid oxidation and investigation of this feature might provide insight into the treatment of diabetic ketoacidosis. The parallels to the metabolic syndrome are likely reflected to varying degrees in other marine mammals, most of which evolved on diets high in lipid and protein content but essentially devoid of carbohydrate. Utilization of these natural models of insulin resistance may further our understanding of the pathophysiology of the metabolic syndrome in humans and better assist the development of preventative measures

    Full Text Available Traditional Chinese medicines have been widely investigated for the treatment of Alzheimer’s disease (AD because none of the current therapies—either the cholinesterase inhibitors or antagonist of N-methyl-d-aspartate receptors—has profound effects on halting the progression of AD. In recent years, scientists have isolated many active compounds from herbs, which can alleviate dementia and neurodegenerative syndrome with fewer side effects than conventional drugs and, thus, are regarded as promising drug candidates for AD therapy. In this review, we summarize the latest research progress on six herbs for AD therapy—Huperzia serrata, Amaryllidaceae family, Ginkgo biloba, Uncaria rhynchophylla, Polygala tenuifolia, and Salvia officinalis—and focus on the analysis of their active components and possible mechanisms of pharmacological actions on AD.

    Full Text Available A decrease in the egg quality, production, fertility and hatchability without serious clinical signs of illness was recorded in turkey fl ocks in Croatia at the beginning of 2002. It was assumed that the egg drop syndrome virus might be one of the etiological agents responsible for the abnormalities in the egg production. The systematic serological monitoring, using a haemagglutination inhibition test, showed that the antibodies to the egg drop syndrome virus existed in 94.4 and 55.1% of the sera analysed in 2002 and 2003, respectively. The haemagglutination inhibition titres ranged from 16 to 128. The sera samples were randomly collected from 11 - to 46-week-old hens from the affected fl ocks. The serological evidence of the egg drop syndrome virus infection was confirmed by detection of the presence of the virus genome in the turkey sera by the polymerase chain reaction. Vaccination of the 18- and 25-week-old turkey hens against the egg drop syndrome virus started in March 2003. After this period, the presence of antibodies to the egg drop syndrome virus (the haemagglutination inhibition titres between 16 and 256 was found in 96.7% of the analysed sera, while the egg production reached normal or higher values for the Nicholas hybrid line of turkeys.

    Polycystic ovary syndrome (PCOS) is a heterogeneous syndrome characterized by oligo- or anovulation, clinical and/or biochemical signs of hyperandrogenemia and polycystic ovaries. Clinical expression is determined by both genetic and environmental factors. Dyslipidemia is very common in lean as well as in obese women with PCOS and should be considered in the therapeutic management of the syndrome. Additionally to dyslipidemia, other risk factors for cardiovascular disease strongly associated with PCOS include insulin resistance, impaired glucose tolerance and metabolic syndrome. Therefore, the ideal therapeutic approach for PCOS would be multi targeted treatment ameliorating not only ovarian dysfunction but also cardiometabolic aspects, including dyslipidemia. Recently, a new era of hypolipidemic agents like statins has been initiated with regard to PCOS. The spectrum of statins' targets has been expanded and in vitro and in vivo studies have explored the specific effect of statins on androgen production, insulin resistance and inflammatory markers in PCOS. Statins are potentially promising therapeutic agents targeting hormonal and metabolic disturbances in PCOS, though conclusive results are still pending. Since several hormonal and metabolic aberrations characterizing this multifaceted syndrome cluster and interact with each other, their effects on the lipid profile are interweaving and the therapeutic modalities targeting dyslipidemia appear to have a more broad beneficial effect.

    Pseudogymnoascus destructans, the fungus that causes white-nose syndrome in hibernating bats, has spread across eastern North America over the past decade and decimated bat populations. The saprotrophic growth of P. destructans may help to perpetuate the white-nose syndrome epidemic, and recent model predictions suggest that sufficiently reducing the environmental growth of P. destructans could help mitigate or prevent white-nose syndrome-associated bat colony collapse. In this study, we screened 301 microbes from diverse environmental samples for their ability to inhibit the growth of P. destructans. We identified 145 antagonistic isolates, 53 of which completely or nearly completely inhibited the growth of P. destructans in co-culture. Further analysis of our best antagonists indicated that these microbes have different modes of action and may have some specificity in inhibiting P. destructans. The results suggest that naturally-occurring microbes and/or their metabolites may be considered further as candidates to ameliorate bat colony collapse due to P. destructans.

  1. Genetic counseling and cascade genetic testing in Lynch syndrome.

    Hampel, Heather

    2016-07-01

    Lynch syndrome is the most common cause of inherited colorectal and endometrial cancers. Individuals with Lynch syndrome have a 10-80 % lifetime risk for colorectal cancer and a 15-60 % lifetime risk for endometrial cancer. Both cancers are preventable through chemoprevention, intensive cancer surveillance, and risk-reducing surgery options. Efforts to identify as many individuals with Lynch syndrome as possible will prevent cancers and save lives. This includes the traditional cancer genetic counseling model whereby individuals with and without cancer are evaluated for a possible Lynch syndrome diagnosis based on their personal and family history of colon polyps and cancers. It also includes universal tumor screening for Lynch syndrome whereby all individuals with colorectal or endometrial cancer are screened for tumor features of Lynch syndrome at the time of diagnosis. Those with tumors suspicious for Lynch syndrome are referred for cancer genetic counseling regardless of their family history of cancer. This two approaches must be maximized to attain high patient reach. Finally, and perhaps most importantly, cascade testing among the at-risk relatives of those diagnosed with Lynch syndrome is critically important to maximize the diagnosis of individuals with Lynch syndrome. In fact, the cost-effectiveness of universal tumor screening for Lynch syndrome relies entirely on counseling and testing as many at-risk individuals as possible since young unaffected individuals stand to benefit the most from an early diagnosis of Lynch syndrome. This approach must be optimized to achieve high family reach. It will take a concerted effort from patients, clinicians and public health officials to improve current approaches to the diagnosis of Lynch syndrome and the prevention and treatment of Lynch syndrome-associated cancer but these lessons can be applied to other conditions as the ultimate example of personalized medicine.

    In July 2010, at the Muscle Fatigue Meeting, I presented an overview of Chronic Fatigue Syndrome and Cancer Related Fatigue, emphasizing a critical interpretation of the potential association between Chronic Fatigue Syndrome and Cancer Related Fatigue and a newly discovered retrovirus: Xenotropic Murine Related Virus. Since this association was hotly debated at that time, I suggested at the Meeting that it was wrong and most likely due to the identification of the wrong virus culprit. Today, 20 months after the Meeting, the first part of our prediction has turned out to be correct, as Xenotropic Murine Related Virus was shown to be a laboratory-created artefact. Still, the potential association of fatigue-syndromes with an infection (most likely viral) is sustained by a plethora of evidence and this overview will initially summarize data suggesting prior viral infection(s). The principal hypothesized mechanisms for both peripheral and central Chronic Fatigue Syndrome/Cancer Related Fatigue will be then summarized, also indicating plausible associations and triggering factors. All evidence accrued so far suggests that further research work should be performed in this interesting area and in order to identify an infectious agent for Chronic Fatigue Syndrome/Cancer Related Fatigue. One candidate RNA virus, Micro-Foci inducing Virus, will be described in this overview. Copyright © 2012 Elsevier B.V. All rights reserved.

    The primary goal of radiotherapy in oncology is to enhance the efficacy of tumor cell death while decreasing damage to surrounding normal cells. Positive therapeutic outcomes may be accomplished by improved targeting, precisely targeting tumor cells or protecting normal cells against radiation-induced damage. The potential for antioxidants to decrease normal tissue damage induced by radiation has been investigated in animal models for a number of decades. In attempts for radioprotection, certain synthetic chemicals are suggested as antioxidants and normal tissue protectors against radiation-induced damage, but they have exhibited limitations in pharmacological application due to undesirable effects and high toxicities at clinical doses. The present review focuses on the radioprotective efficacy of traditional oriental medicines with the advantage of low toxicity at pharmacological doses and how such treatments may influence various harmful effects induced by radiation in vitro and in vivo . In addition, medicinal plants and their active constituents with biological activities that may be associated with alleviation of radiation-induced damage through antioxidant, anti-inflammatory, wound healing and immunostimulatory properties are discussed.

    The metabolic syndrome affects 30% of the US population with increasing prevalence. In this paper, we explore the relationship between the metabolic syndrome and the incidence and severity of cardiovascular disease in general and coronary artery disease (CAD) in particular. Furthermore, we look at the impact of metabolic syndrome on outcomes of coronary revascularization therapies including CABG, PTCA, and coronary collateral development. We also examine the association between the metabolic syndrome and its individual component pathologies and oxidative stress. Related, we explore the interaction between the main external sources of oxidative stress, cigarette smoke and air pollution, and metabolic syndrome and the effect of this interaction on CAD. We discuss the apparent lack of positive effect of antioxidants on cardiovascular outcomes in large clinical trials with emphasis on some of the limitations of these trials. Finally, we present evidence for successful use of antioxidant properties of pharmacological agents, including metformin, statins, angiotensin II type I receptor blockers (ARBs), and angiotensin II converting enzyme (ACE) inhibitors, for prevention and treatment of the cardiovascular complications of the metabolic syndrome.

    Full Text Available Kidney dysfunction and other related abnormalities are extremely common in all HF syndromes, both because of the similarity of risk factors and the similarity of demography of the two types of patients but also because of the common renal effects of agents used for the treatment of HF. Important renal syndromes for the HF patient include including chronic kidney disease, acute kidney injury, cardio-renal syndrome, and prostatic obstruction. In HF (all types including HFrEF, HFmrEF and especially HFpEF chronic kidney disease (CKD frequently co-exists and almost as frequently complicates the HF management. The two groups of syndromes share many risk factors (diabetes, hypertension, hyperlipidaemia and often interact to worsen the prognosis of each other in a way that makes the patient with combined HF and renal disease at extremely high risk. This article reviews this common co-morbidity and how to manage it.

    The prevalence of metabolic syndrome has been increasing in Korea and has been associated with dietary habits. The aim of our study was to identify the relationship between dietary patterns and the prevalence of metabolic syndrome. Using a validated food frequency questionnaire, we employed a cross-sectional design to assess the dietary intake of 1257 Korean adults aged 31 to 70 years. To determine the participants' dietary patterns, we considered 37 predefined food groups in principal components analysis. Metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III. The abdominal obesity criterion was modified using Asian guidelines. Prevalence ratios and 95% confidence intervals for the metabolic syndrome were calculated across the quartiles of dietary pattern scores using log binomial regression models. The covariates used in the model were age, sex, total energy intake, tobacco intake, alcohol consumption, and physical activity. The prevalence of metabolic syndrome was 19.8% in men and 14.1% in women. The PCA identified three distinct dietary patterns: the 'traditional' pattern, the 'meat' pattern, and the 'snack' pattern. There was an association of increasing waist circumference and body mass index with increasing score in the meat dietary pattern. The multivariate-adjusted prevalence ratio of metabolic syndrome for the highest quartile of the meat pattern in comparison with the lowest quartile was 1.47 (95% CI: 1.00-2.15, p for trend = 0.016). A positive association between the prevalence of metabolic syndrome and the dietary pattern score was found only for men with the meat dietary pattern (2.15, 95% CI: 1.10-4.21, p for trend = 0.005). The traditional pattern and the snack pattern were not associated with an increased prevalence of metabolic syndrome. The meat dietary pattern was associated with a higher prevalence of metabolic syndrome in Korean male adults.

    Traditional Chinese medicine (TCM) has played a positive role in the management of hepatocarcinoma. Hepatocarcinoma patients may present Qi-stagnation, damp-heat, blood stasis, Qi-deficiency, Yin-deficiency and other TCM syndromes (Zheng). Modern treatments such as surgery, transarterial chemoembolization (TACE) and high intensity focus ultrasound treatment would influence the manifestation of TCM syndromes. Herbs with traditional efficacy of tonifying Qi, blood and Yin, soothing liver-Qi stagnation, clearing heat and detoxifying and dissolving stasis, have been demonstrated to be potent to prevent hepatocarcinogenesis. TCM has been widely used in all aspects of integrative therapy in hepatocarcinoma, including surgical resection, liver transplantation, TACE, local ablative therapies and even as monotherapy for middle-advanced stage hepatocarcinoma. Clinical practices have confirmed that TCM is effective to alleviate clinical symptoms, improve quality of life and immune function, prevent recurrence and metastasis, delay tumor progression, and prolong survival time in hepatocarcinoma patients. The effective mechanism of TCM against hepatocarcinoma is related to inducing apoptosis, autophagy, anoikis and cell senescence, arresting cell cycle, regulating immune function, inhibiting metastasis and angiogenesis, reversing drug resistance and enhancing effects of chemotherapy. Along with the progress of research in this field, TCM will contribute more to the prevention and treatment of hepatocarcinoma. PMID:26019736

    To evaluate the clinical effect of traditional Chinese spinal orthopedic manipulation (TCSOM) in treating patients with functional abdominal pain syndrome (FAPS) in comparison with Pinaverium Bromide (Dicetel, PBD), and to assess a possible cause for FAPS. Eighty patients with FAPS were randomly and equally assigned to the TCSOM group and PBD group according to the random number table. All patients in the TCSOM group were treated with a maximum of 5 times of spinal manipulations. Patients in the PBD group were instructed to take 50 mg 3 times a day, consistently for 2 weeks. The symptoms of pre- and post-treatment were assessed on a visual analog scale (VAS) pain score. A symptom improvement rating (SIR) was implemented to evaluate the effects of the treatments. The symptoms of 27 cases of the TCSOM group were relieved soon after the first TCSOM treatment and 9 cases were significantly improved. The VAS pain scores in the TCSOM group were significantly lower than those in the PBD group after 2 weeks treatment. According to the SIR based on VAS, the TCSOM group included 30 cases with excellent results, 7 cases with good, and 3 cases with poor. Adverse events to the treatment were not reported. Based on VAS, the PBD group reported 8 cases with excellent results, 10 cases with good and 22 cases with poor. There was a significant difference between the two groups (P<0.01). The displacement of intervertebral discs and/or vertebra in the thoracic or lumbar region seems to be a contributing factor in the symptoms of FAPS. TCSOM is an effective treatment for FAPS.

Were analyzed mainly work on the association of certain types of dietary intake of the population to the risk of metabolic syndrome in several Western and Asian countries. The purpose of these studies was to determine deemed "good" type and the "bad" type of food, risk assessment and exchange of metabolic disorders to determine the optimal dietary recommendations.  Application of factor and cluster analysis allowed in a number of studies to identify groups of products associated with a decrease in the prevalence of metabolic syndrome and to estimate the odds ratios of metabolic syndrome when compared with the "bad" diet.  A number of papers were obtained confirm the effectiveness of the Mediterranean diet in the prevention of metabolic disorders. Commitment to the traditional Western diet is associated with deterioration in health, compared with the recommended "healthy" diet.  Data from epidemiological studies nutrition and metabolic disorders associated with a number of diseases, may be useful in determining how the recommendations on the best type of feeding the population, so to identify ways to further research.

    This review summarizes evidence of dysregulated reward circuitry function in a range of neurodevelopmental and psychiatric disorders and genetic syndromes. First, the contribution of identifying a core mechanistic process across disparate disorders to disease classification is discussed, followed by a review of the neurobiology of reward circuitry. We next consider preclinical animal models and clinical evidence of reward-pathway dysfunction in a range of disorders, including psychiatric disorders (i.e., substance-use disorders, affective disorders, eating disorders, and obsessive compulsive disorders), neurodevelopmental disorders (i.e., schizophrenia, attention-deficit/hyperactivity disorder, autism spectrum disorders, Tourette's syndrome, conduct disorder/oppositional defiant disorder), and genetic syndromes (i.e., Fragile X syndrome, Prader-Willi syndrome, Williams syndrome, Angelman syndrome, and Rett syndrome). We also provide brief overviews of effective psychopharmacologic agents that have an effect on the dopamine system in these disorders. This review concludes with methodological considerations for future research designed to more clearly probe reward-circuitry dysfunction, with the ultimate goal of improved intervention strategies.

    Nodding syndrome has increasingly become an issue of public health concern internationally. The etiology of the disorder is still unknown and there are yet no curative treatments. We explored perceptions about treatment practices and barriers to health seeking for nodding syndrome in Pader and Kitgum districts in northern Uganda in order to provide data necessary for informing policy on treatment adherence and rehabilitations. We used focus group discussions and individual interviews to gain deep insights into help-seeking and treatment practices for nodding syndrome. Purposive sampling was used to identify information-rich participants that included village health teams, community members not directly affected with nodding syndrome, district leaders, healthcare professionals, and caregivers of children affected with nodding syndrome. We used qualitative content analysis to analyze data and presented findings under distinct categories and themes. Caregivers and communities sought care from multiple sources including biomedical facilities, traditional healers, traditional rituals from shrines, and spiritual healing. Nodding syndrome affected children reportedly have showed no enduring improvement with traditional medicines, traditional rituals, and prayers. A substantial minority of participants reported minimal improvements in symptoms of convulsions with use of western medicines. Challenges involved in health seeking included; (1) health system factors e.g. long distances to facilities, frequent unavailability of medicines, few healthcare providers, and long waiting times; (2) contextual and societal challenges e.g. lack of money for transport and medical bills, overburdening nature of the illness that does not allow time for other activities, and practical difficulties involved in transporting the physically deformed and mentally retarded children to the health facilities. Help-seeking for nodding syndrome is pluralistic and include use of traditional and

    The Journal of Research in Crime and Delinquency ( JRCD ) has published important contributions to both criminological theory and associated empirical tests. In this article, we consider some of the challenges associated with traditional approaches to social science research, and discuss a complementary approach that is gaining popularity-agent-based computational modeling-that may offer new opportunities to strengthen theories of crime and develop insights into phenomena of interest. Two literature reviews are completed. The aim of the first is to identify those articles published in JRCD that have been the most influential and to classify the theoretical perspectives taken. The second is intended to identify those studies that have used an agent-based model (ABM) to examine criminological theories and to identify which theories have been explored. Ecological theories of crime pattern formation have received the most attention from researchers using ABMs, but many other criminological theories are amenable to testing using such methods. Traditional methods of theory development and testing suffer from a number of potential issues that a more systematic use of ABMs-not without its own issues-may help to overcome. ABMs should become another method in the criminologists toolbox to aid theory testing and falsification.

    Himsworth in 1939 postulated that Diabetes Mellitus type 2 (DM2) was not only an insulin deficiency state but also a cellular insulin insensitivity disease. Thirty years later, DeFronzo and Reaven demonstrated that insulin resistance (IR) preceded and predisposed for DM2 and atherosclerotic-cardiovascular-disease (ACVD). Reaven was the first to point out the relationship between IR and with hyperglycemia, dyslipidosis, and hypertension as mediators for ACVD, creating the concept of Syndrome X (SX) in 1988. WHO and, thereafter, other medical societies and medical groups, mainly ATP-III, in 2002, based on the difficulty of diagnosing IR in a simple, reliable, and inexpensive way, proposed and published the Metabolic Syndrome (MS) concept, as a group of five variables, i.e., obesity, hyperglycemia, hypertriglyceridemia, low HDL, and hypertension, as an easy clinical approximation to suspect and treat an increased cardiometabolic risk. Nowadays, there are deep and extensive controversies on this issue; however, these controversies do not really exist since all discordant points of view are rather quantitative and not qualitative in nature. This article is aimed at differentiating and harmonizing the complementary concepts of SX and MS, at analyzing why MS is a good "clinical window" to look for IR and its underlying manifestations, and finally to accept that the MS concept complements, but does not substitute or antagonize, traditional scales used to asses cardiovascular risk, such as the Framingham scale.

    2018-04-01

    Full Text Available Agency theory studies have had almost no attention to antecedents of the causes leading agent-principal problem. As there is yet no consensus over what constitutes a perfectly working corporate governance mechanism, this discursive analysis tries to draw attention to the hidden reason of agent-principal problem in order to help the constitution of healthy corporate governance with corporate social responsibility. The purpose is to put forward that Founder’s Syndrome could be one of the reasons behind agency problem and a threat to corporate governance and corporate social responsibility. This paper is the first to extend Agency Theory by associating it with a syndrome analysing the psychological and behavioural instigations of it, which fills the void in literature. A theoretical lens to enhance organizations’ ability to be the corporate social responsibility-focused by overcoming Founder’s Syndrome is provided bearing implications especially for organisational behaviour researchers.

    2017-06-01

    Patients with psoriasis often use botanical therapies as part of their treatment. It is important for clinicians to be aware of the current evidence regarding these agents as they treat patients. A systematic literature search was conducted using the PubMed, MEDLINE, and EMBASE database for randomized clinical trials assessing the use of botanical therapeutics for psoriasis. The search included the following keywords: "psoriasis" and "plant" or "herbal" or "botanical." Citations within articles were also reviewed to identify relevant sources. The results were then further refined by route of administration, and the oral (systemic) botanical agents are reviewed herein. A total of 12 controlled and uncontrolled clinical trials addressing the use of oral, systemic botanical agents for psoriasis were assessed in this review. While overall evidence is limited in quantity and quality, HESA-A, curcumin, neem extract, and, to a lesser degree, Traditional Chinese Medicine seem to be the most efficacious agents. The literature addresses a large amount of studies in regards to botanicals for the treatment of psoriasis. While most agents appear to be safe, further research is necessary for evidence-based recommendation of oral botanical agents to psoriasis patients.

    2017-08-26

    The complexity of gout continues to unravel with each new investigation. Gout sits at the intersection of multiple intrinsically complex processes, and its prevalence, impact on healthcare costs, and association with important co-morbidities make it increasingly relevant. The association between gout and type 2 diabetes, hypertension, hyperlipidemia, cardiovascular disease, renal disease, and obesity suggest that either gout, or its necessary precursor hyperuricemia, may play an important role in the manifestations of the metabolic syndrome. In this review, we analyze the complex interconnections between gout and metabolic syndrome, by reviewing gout's physiologic and epidemiologic relationships with its major co-morbidities. Increasing evidence supports gout's association with metabolic syndrome. More specifically, both human studies and animal models suggest that hyperuricemia may play a role in promoting inflammation, hypertension and cardiovascular disease, adipogenesis and lipogenesis, insulin and glucose dysregulation, and liver disease. Fructose ingestion is associated with increased rates of hypertension, weight gain, impaired glucose tolerance, and dyslipidemia and is a key driver of urate biosynthesis. AMP kinase (AMPK) is a central regulator of processes that tend to mitigate against the metabolic syndrome. Within hepatocytes, leukocytes, and other cells, a fructose/urate metabolic loop drives key inhibitors of AMPK, including AMP deaminase and fructokinase, that may tilt the balance toward metabolic syndrome progression. Preliminary evidence suggests that agents that block the intracellular synthesis of urate may restore AMPK activity and help maintain metabolic homeostasis. Gout is both an inflammatory and a metabolic disease. With further investigation of urate's role, the possibility of proper gout management additionally mitigating metabolic syndrome is an evolving and important question.

  1. Application of blood-pool agents in visualization of peripheral vessels

    2007-01-01

    Effective arterial imaging is essential in patients with peripheral arterial disease (PAD) in whom a revascularization procedure is planned. Digital subtraction angiography (DSA) has traditionally been regarded as the gold standard for imaging in peripheral arterial disease, but this technique is subject to certain limitations, such as the risks of adverse reactions associated with arterial catheterization and iodinated contrast agents. Contrast-enhanced magnetic resonance angiography is now recommended as an effective and useful imaging technique in peripheral arterial disease, since it offers high enhanced contrast between blood and stationary tissue and fast acquisition times. However, extracellular gadolinium contrast agents rapidly diffuse into the interstitial spaces, and thus are suitable only for first-pass imaging. This limitation can be overcome by the use of blood-pool (intravascular) contrast agents, such as gadofosveset trisodium (Vasovist, Bayer Schering Pharma AG, Berlin, Germany), which are retained within the blood vessels and hence facilitate both first-pass and steady-state imaging with high spatial resolution. Blood-pool agents, therefore, offer improved imaging, particularly of distal vessels, compared with extracellular contrast agents. Examples of first-pass and steady-state imaging with gadofosveset are presented. (orig.)

Early diagnosis and treatment of Cushing’s syndrome is associated with a decrease in morbidity and mortality. Clinical presentation can be highly variable, and establishing the diagnosis can often be difficult. Surgery (resection of the pituitary or ectopic source of adrenocorticotropic hormone, or unilateral or bilateral adrenalectomy remains the optimal treatment in all forms of Cushing’s syndrome, but may not always lead to remission. Medical therapy (steroidogenesis inhibitors, agents that decrease adrenocorticotropic hormone levels or glucocorticoid receptor antagonists and pituitary radiotherapy may be needed as an adjunct. A multidisciplinary approach, long-term follow-up, and treatment modalities customized to each individual are essential for optimal control of hypercortisolemia and management of comorbidities.

    Allergic rhinitis (AR) is a common allergic disorder in children, some of whom seek complementary treatments, including acupuncture and Chinese herbs. Little, however, is known about the treatment of pediatric AR with traditional Chinese medicine (TCM). To characterize TCM use in pediatric AR, we conducted a nationwide population-based study. We screened one million randomly sampled beneficiaries of the National Health Insurance Program in Taiwan from 2002 to 2010 to identify children herb was Chan-Tui (Periostracum cicadae; 13.78%). Regarding syndrome differentiation (ZHENG) according to TCM theory, prescriptions for the Cold Syndrome exceeded those for the Hot Syndrome throughout the year in Taiwan. We found that approximately two-thirds of pediatric AR patients were prescribed TCM treatments in Taiwan. Further research is warranted to examine the efficacy and safety of TCM for pediatric AR patients. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    2017-05-18

    The digital transformation of hospitals in Australia is occurring rapidly in order to facilitate innovation and improve efficiency. Rapid transformation can cause temporary disruption of hospital workflows and staff as processes are adapted to the new digital workflows. The aim of this paper is to outline various types of digital disruption and some strategies for effective management. A large tertiary university hospital recently underwent a rapid, successful roll-out of an integrated electronic medical record (EMR). We observed this transformation and propose several digital disruption "syndromes" to assist with understanding and management during digital transformation: digital deceleration, digital transparency, digital hypervigilance, data discordance, digital churn and post-digital 'depression'. These 'syndromes' are defined and discussed in detail. Successful management of this temporary digital disruption is important to ensure a successful transition to a digital platform. What is known about this topic? Digital disruption is defined as the changes facilitated by digital technologies that occur at a pace and magnitude that disrupt established ways of value creation, social interactions, doing business and more generally our thinking. Increasing numbers of Australian hospitals are implementing digital solutions to replace traditional paper-based systems for patient care in order to create opportunities for improved care and efficiencies. Such large scale change has the potential to create transient disruption to workflows and staff. Managing this temporary disruption effectively is an important factor in the successful implementation of an EMR. What does this paper add? A large tertiary university hospital recently underwent a successful rapid roll-out of an integrated electronic medical record (EMR) to become Australia's largest digital hospital over a 3-week period. We observed and assisted with the management of several cultural, behavioural and

    A new wireless sensing network paradigm is presented for structural monitoring applications. In this approach, both power and data interrogation commands are conveyed via a mobile agent that is sent to sensor nodes to perform intended interrogations, which can alleviate several limitations of the traditional sensing networks. Furthermore, the mobile agent provides computational power to make near real-time assessments on the structural conditions. This paper will discuss such prototype systems, which are used to interrogate impedance-based sensors for structural health monitoring applications. Our wireless sensor node is specifically designed to accept various energy sources, including wireless energy transmission, and to be wirelessly triggered on an as-needed basis by the mobile agent or other sensor nodes. The capabilities of this proposed sensing network paradigm are demonstrated in the laboratory and the field

    Traditional Chinese Medicine (tcm) is used in China as part of the treatment for non-small-cell lung cancer (nsclc) and often includes prescription of herbal therapy based on syndrome differentiation. Studies of various Astragalus-based Chinese medicines combined with platinum-based chemotherapy in the treatment of lung cancer are popular in East Asia, particularly in China. The aim of the present study was to perform a systematic review and meta-analysis comparing platinum-based chemotherapy alone with platinum-based chemotherapy plus Astragalus-based Chinese botanicals, with and without prescription based on syndrome differentiation, as first-line treatment for advanced nsclc. We searched the Chinese Biomedical Literature database, the China National Knowledge Internet, the VIP Chinese Science and Technology Periodicals Database, PubMed, embase, the Cochrane databases, and abstracts presented at meetings of the American Society of Clinical Oncology, the World Conference on Lung Cancer, the European Society for Medical Oncology, and the Chinese Society of Clinical Oncology for all eligible studies. Endpoints were overall survival; 1-year, 2-year, and 3-year survival rates; performance status; overall response rate; and grade 3 or 4 adverse events. Subgroup analyses based on herbal formulae individualized using syndrome differentiation or on oral or injection patent medicines were performed using the Stata software application (version 11.0: StataCorp LP, College Station, TX, U.S.A.) and a fixed-effects or random-effects model in case of heterogeneity. Results are expressed as a hazard ratio (hr) or relative risk (rr), with corresponding 95% confidence intervals (cis). Seventeen randomized studies with scores on the Jadad quality scale of 2 or more, representing 1552 patients, met the inclusion criteria. Compared with platinum-based chemotherapy alone, the addition of Astragalus-based tcm to chemotherapy was associated with significantly increased overall survival

    A girl with Down's syndrome, moyamoya disease and sagittal sinus thrombosis is described. She was diagnosed after acute neurological deterioration by MRI and angiography. Recombinant tissue plasminogen activator (r-TPA) was injected locally to recanalise the thrombus. The patient's condition significantly improved and she was discharged. After 2 years of follow-up the child remains asymptomatic. Moyamoya syndrome and cerebral venous thrombosis should not be overlooked as a cause of acute neurological deterioration in a child with Down's syndrome. MRA appears to be a safe and accurate alternative to traditional angiography for the diagnosis of moyamoya disease. Local fibrinolysis with r-TPA is the treatment of choice for cerebral venous thrombosis due to its safety and efficacy. (orig.)

    In the past few decades, advances in imaging equipment and protocols have expanded the role of imaging in in vivo diagnosis and disease management, especially in cancer. Traditional imaging agents have rapid clearance and low specificity for disease detection. To improve accuracy in disease identification, localization and assessment, novel nanomaterials are frequently explored as imaging agents to achieve high detection specificity and sensitivity. A promising material for this purpose are hydrogel nanoparticles, whose high hydrophilicity, biocompatibility, and tunable size in the nanometer range make them ideal for imaging. These nanogels (10 to 200 nm) can circumvent uptake by the reticuloendothelial system, allowing longer circulation times than small molecules. In addition, their size/surface properties can be further tailored to optimize their pharmacokinetics for imaging of a particular disease. Herein, we provide a comprehensive review of nanogels as imaging agents in various modalities with sources of signal spanning the electromagnetic spectrum, including MRI, NIR, UV-vis, and PET. Many materials and formulation methods will be reviewed to highlight the versatility of nanogels as imaging agents.

    Polycystic ovary syndrome (PCOS) is an endocrine disease that affects gynecological health. Treatment of PCOS remains a big challenge for clinicians. This meta-analysis was developed to compare the efficacy of co-treatment with traditional Chinese medicine (TCM) and letrozole against letrozole monotherapy in the treatment of PCOS. Randomized controlled trials (RCTs) were electronically retrieved from PubMed, Cochrane Library, China Biomedical Literature Database, China National Knowledge Infrastructure and Wanfang Data; related papers that were not available electronically were manually checked. All papers were assessed according to the Cochrane Handbook for Systematic Reviews of Interventions and the valid data were analyzed using Revman software (The Cochrane Collaboration, Copenhagen, Denmark). We included RCTs that compared co-treatment with TCM and letrozole against letrozole monotherapy in women with PCOS, which was defined by anovulation, biochemical or clinical hyperandrogenemia and polycystic ovaries. We included trials from all sources. Two independent reviewers extracted data, and evaluated study quality according to the Cochrane Handbook for Systematic Reviews of Interventions criteria for RCT, including issues of patient randomization, blinding and bias. Eight RCTs, involving a total of 537 patients, were included in the present study. The meta-analysis showed that the cycle ovulation rate, the pregnancy rate and the total effective rate of symptom treatment were higher in treatments combining TCM with letrozole, compared with letrozole monotherapy. Although the rate of luteinizing hormone (LH)/follicle-stimulating hormone (FSH) and the body mass index of the group receiving combined therapy were lower than in letrozole monotherapy, no statistical difference was found in the LH and FSH level between the two groups. Available evidence showed that co-treatment with TCM and letrozole was more effective than letrozole monotherapy in the treatment of PCOS.

    Full Text Available Paliperidone, an active metabolite of risperidone, is a new atypical antipsychotic agent. Syndrome of inappropriate antidiuretic hormone (SIADH, neuroleptic malignant syndrome (NMS, and rhabdomyolysis are the uncommon side effects of psychotropic drugs. We report a case of 35-year-old male with schizoaffective disorder who was admitted for acute-on-chronic exacerbation of his psychotic disorder for which intramuscular paliperidone 234 mg injection was given. Two days later, the patient developed hyponatremic seizures secondary to SIADH which was treated with hypertonic saline. On the third day, he developed high grade fever and severe muscle rigidity with raised creatine phosphokinase (CPK and liver enzymes levels. He was treated with dantrolene 100 mg, bromocriptine 2.5 mg, and lorazepam 2 mg. Our patient required management of the three rare conditions following treatment with paliperidone. This case highlights the need for health care providers to be aware of the rare, potentially life threatening but preventable hyponatremia, NMS, and rhabdomyolysis as a possible adverse effect of paliperidone.

    Full Text Available Abstract This review summarizes evidence of dysregulated reward circuitry function in a range of neurodevelopmental and psychiatric disorders and genetic syndromes. First, the contribution of identifying a core mechanistic process across disparate disorders to disease classification is discussed, followed by a review of the neurobiology of reward circuitry. We next consider preclinical animal models and clinical evidence of reward-pathway dysfunction in a range of disorders, including psychiatric disorders (i.e., substance-use disorders, affective disorders, eating disorders, and obsessive compulsive disorders, neurodevelopmental disorders (i.e., schizophrenia, attention-deficit/hyperactivity disorder, autism spectrum disorders, Tourette’s syndrome, conduct disorder/oppositional defiant disorder, and genetic syndromes (i.e., Fragile X syndrome, Prader–Willi syndrome, Williams syndrome, Angelman syndrome, and Rett syndrome. We also provide brief overviews of effective psychopharmacologic agents that have an effect on the dopamine system in these disorders. This review concludes with methodological considerations for future research designed to more clearly probe reward-circuitry dysfunction, with the ultimate goal of improved intervention strategies.

    Full Text Available The recognition, evaluation, and early treatment of nephrotic syndrome in infants and children originates from physicians dating back to Hippocrates. It took nearly another thousand years before the condition was described for its massive edema requiring treatment with herbs and other remedies. A rich history of observations and interpretations followed over the course of centuries until the recognition of the combination of clinical findings of foamy urine, swelling of the body, and measurements of urinary protein and blood analyses showed the phenotypic characteristics of the syndrome that were eventually linked to the early anatomic descriptions from first kidney autopsies and then renal biopsy analyses. Coincident with these findings were a series of treatment modalities involving the use of natural compounds to a host of immunosuppressive agents that are applied today. With the advent of molecular and precision medicine, the field is poised to make major advances in our understanding and effective treatment of nephrotic syndrome and prevent its long-term sequelae.

    Full Text Available Cardiovascular disease is the leading cause of death in patients with chronic kidney disease.  Heart failure may lead to acute kidney injury and vice versa. Chronic kidney disease may affect the clinical outcomes in patients with cardiovascular disorders. Renal impairment with any degree of albuminuria has been increasingly recognized as an independent risk factor for cardiovascular events and heart failure hospitalizations, while chronic heart failure may cause chronic kidney disease. The bidirectional nature of these disorders contributes to the complexity and the composite definitions of cardiorenal syndromes. However, the most important clinical trials in heart failure tend to exclude patients with significant renal dysfunction. The mechanisms whereby renal insufficiency worsens the outcome in heart failure are not known, and several pathways could contribute to the ‘‘vicious heart/kidney circle.’’ Traditionally, renal impairment has been attributed to the renal hypoperfusion due to reduced cardiac output and decreased systemic pressure. The hypovolemia leads to sympathetic activity, increased renin-angiotensin aldosterone pathway, and arginine-vasopressin release. These mechanisms cause fluid and sodium retention, peripheral vasoconstriction, and volume overload. Therapy to improve renal dysfunction, reduce neurohormonal activation and ameliorate renal blood flow could lead to a reduction in mortality and hospitalization in patients with cardiorenal syndrome.

  7. ‘Gas Syndrome’ - A Culture Bound Syndrome

    2014-02-01

    Full Text Available Culture refers to the shared patterns of feelings, beliefs and behaviour that reflect in the way of living in a society. Culture uniquely influence the role functioning or psychosoical wellbeing of people living in a given society by exerting influence on their mind by their traditional health beliefs. Cultural factors influence understanding, presentation, diagnosis, management, course and outcome of many diseases, especially psychiatric disorders. Culture-bound syndromes seem to be episodic, dramatic and discrete patterns of behavioral reactions specific to a particular community that articulate both personal predicament and public concerns. Every culture provides explanations and causal attributions for somatic symptoms. One of the common complaints of persons coming to medical attention is ‘Gas’ or similar terminologies like ‘vayu’ etc. People attribute varied symptoms from abdominal discomfort, chest pain, headache, joint pains, back pain, somatic complaints to ‘Gas’. ‘Gas’ is reported to be the cause for the distress and the primary duty of the treating clinician is to relieve them of the gas. The problem of troubling Gas or vayu has been influencing Indian culture/tradition since ancient days. We do see a significant proportion of patients visiting varied specialists attributing all their problems to Gas. 'Gas Syndrome’ is proposed as a culture bound syndrome.

    The amount of biomedical data in different disciplines is growing at an exponential rate. Integrating these significant knowledge sources to generate novel hypotheses for systems biology research is difficult. Traditional Chinese medicine (TCM) is a completely different discipline, and is a complementary knowledge system to modern biomedical science. This paper uses a significant TCM bibliographic literature database in China, together with MEDLINE, to help discover novel gene functional knowledge. We present an integrative mining approach to uncover the functional gene relationships from MEDLINE and TCM bibliographic literature. This paper introduces TCM literature (about 50,000 records) as one knowledge source for constructing literature-based gene networks. We use the TCM diagnosis, TCM syndrome, to automatically congregate the related genes. The syndrome-gene relationships are discovered based on the syndrome-disease relationships extracted from TCM literature and the disease-gene relationships in MEDLINE. Based on the bubble-bootstrapping and relation weight computing methods, we have developed a prototype system called MeDisco/3S, which has name entity and relation extraction, and online analytical processing (OLAP) capabilities, to perform the integrative mining process. We have got about 200,000 syndrome-gene relations, which could help generate syndrome-based gene networks, and help analyze the functional knowledge of genes from syndrome perspective. We take the gene network of Kidney-Yang Deficiency syndrome (KYD syndrome) and the functional analysis of some genes, such as CRH (corticotropin releasing hormone), PTH (parathyroid hormone), PRL (prolactin), BRCA1 (breast cancer 1, early onset) and BRCA2 (breast cancer 2, early onset), to demonstrate the preliminary results. The underlying hypothesis is that the related genes of the same syndrome will have some biological functional relationships, and will constitute a functional network. This paper presents

    The intestinal tract is inhabited by a large and diverse community of microbes collectively referred to as the gut microbiota. While the gut microbiota provides important benefits to its host, especially in metabolism and immune development, disturbance of the microbiota-host relationship is associated with numerous chronic inflammatory diseases, including inflammatory bowel disease and the group of obesity-associated diseases collectively referred to as metabolic syndrome. A primary means by which the intestine is protected from its microbiota is via multi-layered mucus structures that cover the intestinal surface, thereby allowing the vast majority of gut bacteria to be kept at a safe distance from epithelial cells that line the intestine. Thus, agents that disrupt mucus-bacterial interactions might have the potential to promote diseases associated with gut inflammation. Consequently, it has been hypothesized that emulsifiers, detergent-like molecules that are a ubiquitous component of processed foods and that can increase bacterial translocation across epithelia in vitro, might be promoting the increase in inflammatory bowel disease observed since the mid-twentieth century. Here we report that, in mice, relatively low concentrations of two commonly used emulsifiers, namely carboxymethylcellulose and polysorbate-80, induced low-grade inflammation and obesity/metabolic syndrome in wild-type hosts and promoted robust colitis in mice predisposed to this disorder. Emulsifier-induced metabolic syndrome was associated with microbiota encroachment, altered species composition and increased pro-inflammatory potential. Use of germ-free mice and faecal transplants indicated that such changes in microbiota were necessary and sufficient for both low-grade inflammation and metabolic syndrome. These results support the emerging concept that perturbed host-microbiota interactions resulting in low-grade inflammation can promote adiposity and its associated metabolic effects

    Recent success of immunotherapy and other targeted therapies in cancer treatment has led to an unprecedented surge in the number of novel therapeutic agents that need to be evaluated in clinical trials. Traditional phase II clinical trial designs were developed for evaluating one candidate treatment at a time and thus not efficient for this task. We propose a Bayesian phase II platform design, the multi-candidate iterative design with adaptive selection (MIDAS), which allows investigators to continuously screen a large number of candidate agents in an efficient and seamless fashion. MIDAS consists of one control arm, which contains a standard therapy as the control, and several experimental arms, which contain the experimental agents. Patients are adaptively randomized to the control and experimental agents based on their estimated efficacy. During the trial, we adaptively drop inefficacious or overly toxic agents and 'graduate' the promising agents from the trial to the next stage of development. Whenever an experimental agent graduates or is dropped, the corresponding arm opens immediately for testing the next available new agent. Simulation studies show that MIDAS substantially outperforms the conventional approach. The proposed design yields a significantly higher probability for identifying the promising agents and dropping the futile agents. In addition, MIDAS requires only one master protocol, which streamlines trial conduct and substantially decreases the overhead burden. Copyright © 2016 John Wiley & Sons, Ltd.

  11. A physical data model for fields and agents

    2016-04-01

    Two approaches exist in simulation modeling: agent-based and field-based modeling. In agent-based (or individual-based) simulation modeling, the entities representing the system's state are represented by objects, which are bounded in space and time. Individual objects, like an animal, a house, or a more abstract entity like a country's economy, have properties representing their state. In an agent-based model this state is manipulated. In field-based modeling, the entities representing the system's state are represented by fields. Fields capture the state of a continuous property within a spatial extent, examples of which are elevation, atmospheric pressure, and water flow velocity. With respect to the technology used to create these models, the domains of agent-based and field-based modeling have often been separate worlds. In environmental modeling, widely used logical data models include feature data models for point, line and polygon objects, and the raster data model for fields. Simulation models are often either agent-based or field-based, even though the modeled system might contain both entities that are better represented by individuals and entities that are better represented by fields. We think that the reason for this dichotomy in kinds of models might be that the traditional object and field data models underlying those models are relatively low level. We have developed a higher level conceptual data model for representing both non-spatial and spatial objects, and spatial fields (De Bakker et al. 2016). Based on this conceptual data model we designed a logical and physical data model for representing many kinds of data, including the kinds used in earth system modeling (e.g. hydrological and ecological models). The goal of this work is to be able to create high level code and tools for the creation of models in which entities are representable by both objects and fields. Our conceptual data model is capable of representing the traditional feature data

    Wolff-Parkinson-White (WPW) syndrome is a disease associated with episodes of supraventricular tachycardia and ventricular pre-excitation or atrial fibrillation. WPW is characterized by an aberrant electrical conduction pathway between atria and ventricles. The major anesthetic problem connected with WPW syndrome is the risk of tachyarrhythmias due to accessory pathway. Therefore, it has been proposed that the aim of anesthetic management should be the avoidance of tachyarrhythmia and sympathetic stimulation. Sugammadex was administered as a neuromuscular reversal agent in this case. To our knowledge, this is the first case report of sugammadex use in a patient with WPW. This report presents a case of general anesthesia management in a patient with WPW syndrome. We think that it is appropriate to use sugammadex to reverse rocuronium for the prevention of sudden hemodynamic changes in patients with WPW who underwent general anesthesia.

    Centropontine myelinolysis (CPM) is a rare neurologic disorder defined by symmetric demyelination in the central pons, mostly due to alcoholism, malnutrition, or water-electrolyte abnormalities. We report an unusual case of CPM likely due to hypophosphatemia, related to a refeeding syndrome in the context of mental anorexia. A 15-year-old girl with mental anorexia presented with hypophosphatemia in the following days of enteral refeeding, and then suffered from confusion, neurological signs, and typical MRI lesions of CPM. Hypophosphoremia may be considered as a causative agent in CPM related to refeeding syndrome. This clinical observation also highlights the importance of recognizing patients at high risk of refeeding syndrome to initiate a balanced nutrition with careful monitoring.

    Calcium channel blockers (CCBs) are prescribed to patients with Marfan syndrome for prophylaxis against aortic aneurysm progression, despite limited evidence for their efficacy and safety in the disorder. Unexpectedly, Marfan mice treated with CCBs show accelerated aneurysm expansion, rupture, and premature lethality. This effect is both extracellular signal-regulated kinase (ERK1/2) dependent and angiotensin-II type 1 receptor (AT1R) dependent. We have identified protein kinase C beta (PKCβ) as a critical mediator of this pathway and demonstrate that the PKCβ inhibitor enzastaurin, and the clinically available anti-hypertensive agent hydralazine, both normalize aortic growth in Marfan mice, in association with reduced PKCβ and ERK1/2 activation. Furthermore, patients with Marfan syndrome and other forms of inherited thoracic aortic aneurysm taking CCBs display increased risk of aortic dissection and need for aortic surgery, compared to patients on other antihypertensive agents.

    Tartrate-resistant phosphatase isoform 5a is expressed in tumor-associated macrophages and is a biomarker of chronic inflammation. Herein, we correlated serum tartrate-resistant phosphatase isoform 5a levels with metabolic syndrome status and made comparisons with traditional markers of inflammation, including c-reactive protein and interleukin-6. One hundred healthy volunteers were randomly selected, and cut-off points for metabolic syndrome related inflammatory biomarkers were determined using receiver operating characteristic curves. Linear and logistic regression models were subsequently used to correlate inflammatory markers with the risk of metabolic syndrome. Twenty-two participants met the criteria for metabolic syndrome, and serum tartrate-resistant phosphatase isoform 5a levels of >5.8 μg/L were associated with metabolic syndrome (c-statistics, 0.730; p = 0.001; 95% confidence interval, 0.618-0.842). In addition, 1 μg/L increases in tartrate-resistant phosphatase isoform 5a levels were indicative of a 1.860 fold increase in the risk of metabolic syndrome (p = 0.012). Elevated serum tartrate-resistant phosphatase isoform 5a levels are associated with the risk of metabolic syndrome, with a cut-off level of 5.8 μg/L.

    Two oral antiplatelet agents have been recently introduced for acute coronary syndromes indication providing alternatives for dual therapy with aspirin and clopidogrel. In fact, worldwide prasugrel has been on the market for four years, and ticagrelor for over two years. Despite declared benefits over clopidogrel, including hypothetical cost saving advantages, in real life, the clinical utilisation of both agents is small. Generic clopidogrel, and price differences are claimed as major obstacles to prevent broader prasugrel and ticagrelor use. However, these economic difficulties are barely supported by available evidence, and served mostly to protect questionable management spending, as an exuse to explain why in reality cardiologists are so sceptical about both novel agents, and to convince the sharehoders that their money is not wasted, misleading the owners with regard to future success. Importantly, brand Plavix® is used worldwide 5-10 times more often than new agents, despite heavy generic competition. The future of prasugrel outside Japan, where much lower reasonable dose will be used is not impressive due to lack of further outcome studies, negative results of the latest trials, and less than four years left before patent expiration. The fate of ticagrelor will depend on verification of deaths numbers in the ongoing United States Department of Justice PLATO investigation, and confirmation of the mortality benefit in the PEGASUS TIMI-54 trial.

    To compare changes in enamel microhardness adjacent to orthodontic brackets after using bonding agents containing various compositions of bioactive glass compared to a traditional resin adhesive following a simulated caries challenge. Extracted human third molars (n  =  10 per group) had orthodontic brackets bonded using one of four novel bioactive glass (BAG)-containing orthodontic bonding agents (BAG-Bonds) or commercially available Transbond-XT. The four new adhesives contained BAG in varying percentages incorporated into a traditional resin monomer mixture. Teeth were cycled through low-pH demineralizing and physiologic-pH remineralizing solutions once each day over 14 days. Microhardness was measured on longitudinal sections of the teeth 100, 200, and 300 µm from the bracket edge and beneath the brackets, at depths of 25 to 200 µm from the enamel surface. Normalized hardness values were compared using three-way analysis of variance. Significantly less reduction in enamel microhardness was found with the experimental adhesives at depths of 25 and 50 µm at all distances from the bracket edge. In all groups, there were no significant changes in enamel microhardness past 125-µm depth. Results varied with the different BAG-Bonds, with 81BAG-Bond showing the smallest decrease in enamel microhardness. The BAG-Bonds tested in this study showed a reduction in the amount of superficial enamel softening surrounding orthodontic brackets compared to a traditional bonding agent. The results indicate that clinically, BAG-Bonds may aid in maintaining enamel surface hardness, therefore helping prevent white spot lesions adjacent to orthodontic brackets.

    Full Text Available Background and Design: Psoriasis is a chronic inflammatory immun mediated skin disorder with unknown etiology. The chronic inflammation in psoriasis have role in the development of metabolic and vascular disorders related with associating comorbidities. Recent studies have suggested a strong association exists between metabolic syndrome, obesity and complexity of the association between psoriasis, body mass index (BMI and psoriasis tratment. In this study, our aim was to investigate the effect of psoriasis treatment with methotrexate, cyclosporine and biological agents on body composition, comorbidities and associated laboratory findings. Materials and Methods: Seventy-nine patients treated with methotrexate, cyclosporin and biological agents were included in our study. Demographic characteristics, body composition analysis, psoriasis related comorbidities and laboratory examinations were evaluated before and after 12 weeks of systemic treatment. Results: Comorbidities and metabolic syndrome tended to be more frequent in the anti tumor necrosis factor alpha (anti-TNF-α treated group.

    TAFRO syndrome is a systemic inflammatory disorder characterized by thrombocytopenia, anasarca, fever, reticulin fibrosis, renal dysfunction, and organomegaly. In contrast to that in multicentric Castleman disease, interleukin-6 targeting strategies seem ineffective in some TAFRO syndrome cases; however, the optimal treatment remains unclear. Here, we report 2 cases of TAFRO syndrome, where 1 with cardiomyopathy, successfully treated with tacrolimus. This is the first case report of successful treatment with tacrolimus in TAFRO syndrome. Both patients (cases 1 and 2) developed fever, anasarca, thrombocytopenia, renal dysfunction, and mild hepatosplenomegaly. In both patients, lymph node pathology revealed mixed type Castleman disease-like features, and bone marrow showed reticulin myelofibrosis. TAFRO syndrome was diagnosed based on the patients' laboratory, clinical, and pathologic findings. In case 2, we observed a rare complication of cardiomyopathy with no evidence of takotsubo cardiomyopathy or viral myocarditis. In case 1, tocilizumab combined with glucocorticoids was ineffective and caused septic shock; additionally, cyclosporine A was discontinued because of hepatotoxicity. However, tacrolimus was effective in resolving TAFRO syndrome without any adverse events. In case 2, tacrolimus completely reversed TAFRO syndrome and was also effective in cardiomyopathy. This report suggests that tacrolimus is potentially effective and safe as an initial treatment and a glucocorticoid-sparing agent. Our literature review shows that calcineurin inhibitors, including tacrolimus, may be effective in TAFRO syndrome. Since previous studies indicate a role of Th1 inflammation in TAFRO syndrome pathogenesis, tacrolimus may, therefore, be effective in treating TAFRO syndrome.

    To report the indications and safety of biologic agents in childhood rheumatic diseases at a tertiary hospital. Children with rheumatic diseases treated with biologic agents at King Faisal Specialist Hospital and Research Center, Riyadh, Saudi Arabia, from January 2001 to December 2011 were included. All patients were reviewed for: demographic characteristics, diagnosis, concomitant treatment and indications of using biologic agents, age at start of therapy and side effects during the treatment period. In all, 134 children (89 female) with various rheumatic diseases were treated with biologic agents. Mean age at starting biologic treatment was 9.3 (4.25-14) years and mean therapy duration was 14.7 (3-88) months. Juvenile idiopathic arthritis (JIA) was the most frequent diagnosis (70.1%) followed by systemic lupus erythematosus (12.7%) and vasculitis (4.5%). All patients received concomitant therapy (corticosteroids and disease-modifying antirheumatic drugs). In total, 273 treatments with biologic agents were used, (95 etanercept, 52 rituximab, 47 adalimumab, 37 infliximab, 23 anakinra, 10 tocilizumab and nine abatacept). Therapy was switched to another agent in 57 (42.5%) patients, mainly because of inefficacy (89.4%) or adverse event (10.6%). A total of 95 (34.8%) adverse events were notified; of these, the most frequent were infusion-related reactions (33.7%) followed by infections (24.2%) and autoantibody positivity (10.6%). One patient developed macrophage activation syndrome. Biologic agents were used in children with a range of rheumatic diseases. Of these, the most frequent was JIA. Off-label use of biologic agents in our cohort is common. These agents seem safe. However, they may associated with various adverse events. Sequential therapy seems well tolerated. However, this should be carefully balanced and considered on an individual basis. © 2014 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

    White-nose syndrome (WNS) has claimed the lives of millions of hibernating insectivorous bats in North America. Its etiologic agent, the psychrophilic fungus Geomyces destructans, causes skin lesions that are the hallmark of the disease. The fungal infection is characterized by a white powdery growth on muzzle, ears and wing membranes. While WNS may threaten some species of North American bats with regional extinction, infection in hibernating bats in Europe seems not to be associated with significant mortality. We performed histopathological investigations on biopsy samples of 11 hibernating European bats, originating from 4 different countries, colonized by G. destructans. One additional bat was euthanized to allow thorough examination of multiple strips of its wing membranes. Molecular analyses of touch imprints, swabs and skin samples confirmed that fungal structures were G. destructans. Additionally, archived field notes on hibernacula monitoring data in the Harz Mountains, Germany, over an 11-year period (2000-2011) revealed multiple capture-recapture events of 8 banded bats repeatedly displaying characteristic fungal colonization. Skin lesions of G. destructans-affected hibernating European bats are intriguingly similar to the epidermal lesions described in North American bats. Nevertheless, deep invasion of fungal hyphae into the dermal connective tissue with resulting ulceration like in North American bats was not observed in the biopsy samples of European bats; all lesions found were restricted to the layers of the epidermis and its adnexae. Two bats had mild epidermal cupping erosions as described for North American bats. The possible mechanisms for any difference in outcomes of G. destructans infection in European and North American bats still need to be elucidated.

    Near-death experiences (NDEs), transcendental experiences on the threshold of death with profound implications for both patient care and religious belief, have been hypothesized to be related to the awakening of a biological process known in Eastern traditions as kundalini. In a test of this proposed association between kundalini and NDEs, a sample of near-death experiencers acknowledged significantly more symptoms of a physio-kundalini syndrome than did control subjects.

    Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common condition that causes severe symptoms, bother, and quality-of-life impact in the 8.2% of men who are believed to be affected. Research suggests a complex pathophysiology underlying this syndrome that is mirrored by its heterogeneous clinical presentation. Management of patients diagnosed with CP/CPPS has always been a formidable task in clinical practice. Due to its enigmatic etiology, a plethora of clinical trials failed to identify an efficient monotherapy. A comprehensive review of published randomized controlled trials (RCTs) on the treatment of CP/CPPS and practical best evidence recommendations for management. Medline and the Cochrane database were screened for RCTs on the treatment of CP/CPPS from 1998 to December 2014, using the National Institutes of Health Chronic Prostatitis Symptom Index as an objective outcome measure. Published data in concert with expert opinion were used to formulate a practical best evidence statement for the management of CP/CPPS. Twenty-eight RCTs identified were eligible for this review and presented. Trials evaluating antibiotics, α-blockers, anti-inflammatory and immune-modulating substances, hormonal agents, phytotherapeutics, neuromodulatory drugs, agents that modify bladder function, and physical treatment options failed to reveal a clear therapeutic benefit. With its multifactorial pathophysiology and its various clinical presentations, the management of CP/CPPS demands a phenotypic-directed approach addressing the individual clinical profile of each patient. Different categorization algorithms have been proposed. First studies applying the UPOINTs classification system provided promising results. Introducing three index patients with CP/CPPS, we present practical best evidence recommendations for management. Our current understanding of the pathophysiology underlying CP/CPPS resulting in this highly variable syndrome does not speak in favor of a

    This paper systematically studies relevant literatures at home and abroad in recent years. China National Knowledge Internet (CNKI) was used to collect the literatures for acute pharyngitis treated with traditional Chinese medicine from January 1, 2006, to December 31, 2016, and the bibliometric method was employed for statistical analysis. A total of 493 papers were preliminarily selected. According to the inclusion criteria and exclusion criteria, 182 eligible articles were selected. According to the evaluation and analysis of the literatures, the Guidelines for Clinical Research of New Drugs is currently used as the common standards for the diagnosis and treatment of acute pharyngitis; Chinese patent medicines are the main traditional Chinese medicine for treating this disease; Decoctions for treatment of this disease include Lonicerae Japonicae Flos, Scutellariae Radix, Platycodonis Radix, Forsythiae Fructus, Glycyrrhizae Radix et Rhizoma, Scrophdlariae Radix, Isatidis Radix, and Ophiopogonis Radix; The bloodletting puncture is the common external therapy. Traditional Chinese medicine and Western medicine have their own characteristics in the treatment of this disease. Western medicine for the treatment of acute pharyngitis are mainly antiviral, antibiotic and glucocorticoid drugs, whose disadvantages are toxicity, side effects, drug resistance and double infections. Traditional Chinese medicine doctors have rich experiences in the treatment of the disease, which is characterized by treatment determination based on syndrome differentiation, safe and reliable medication, significant curative effect, low drug resistance, and wide varieties of traditional Chinese medicine forms, convenient portability and taking, low price, and low toxic and side effects. It is an arduous and significant task to explore traditional Chinese medicine, and study and develop new-type effective drugs. Copyright© by the Chinese Pharmaceutical Association.

  15. Agent Based Modeling Applications for Geosciences

    Science.gov (United States)

    Stein, J. S.

    2004-12-01

    Agent-based modeling techniques have successfully been applied to systems in which complex behaviors or outcomes arise from varied interactions between individuals in the system. Each individual interacts with its environment, as well as with other individuals, by following a set of relatively simple rules. Traditionally this "bottom-up" modeling approach has been applied to problems in the fields of economics and sociology, but more recently has been introduced to various disciplines in the geosciences. This technique can help explain the origin of complex processes from a relatively simple set of rules, incorporate large and detailed datasets when they exist, and simulate the effects of extreme events on system-wide behavior. Some of the challenges associated with this modeling method include: significant computational requirements in order to keep track of thousands to millions of agents, methods and strategies of model validation are lacking, as is a formal methodology for evaluating model uncertainty. Challenges specific to the geosciences, include how to define agents that control water, contaminant fluxes, climate forcing and other physical processes and how to link these "geo-agents" into larger agent-based simulations that include social systems such as demographics economics and regulations. Effective management of limited natural resources (such as water, hydrocarbons, or land) requires an understanding of what factors influence the demand for these resources on a regional and temporal scale. Agent-based models can be used to simulate this demand across a variety of sectors under a range of conditions and determine effective and robust management policies and monitoring strategies. The recent focus on the role of biological processes in the geosciences is another example of an area that could benefit from agent-based applications. A typical approach to modeling the effect of biological processes in geologic media has been to represent these processes in

    The Siamese fighting fish (Betta splendens) is one of the popular aquarium ornamental fish in the global trade. Large numbers of ornamental fish farmed in central Thailand suffered from two common syndromes; preliminarily named skin nodule syndrome (SNS) and big belly syndrome (BBS): they showed noticeable clinical signs of abnormal appearances resulting in depressed saleability. Since very few specifics are known about causative agents of these syndromes, this study aimed at investigating histopathological features and culturable bacteria associated with these fish infected in the process of farming. Histopathologically, SNS fish consistently exhibited necrosis and severe melanization in the muscles and multiple internal organs. Whereas BBS fish exhibited either typical granulomas or tissue damage associated with acid-fast stained bacteria and Gram negative bacteria, respectively. Six different Gram negative bacterial species were recovered from BBS fish while 23 bacterial species belonging to 14 genera were recovered from fish suffering from SNS. Most of the culturable bacteria are new to betta fish and some of them are known to be marine bacteria, suggesting possible entry route via a contaminated live feed, commercial Artemia shrimp. The true causative agents of these syndromes remain unclear. However, histopathological changes and existence of a wide range of bacteria associated with the naturally diseased fish suggest involvement of multiple bacterial infections.

    The reversible posterior leukoencephalopathy syndrome is a clinical/radiological syndrome characterized by headache, seizures, impaired vision, acute hypertension, and typical magnetic resonance imaging findings. There are several reports in the literature that depict its occurrence in cancer patients. The list of common anticancer and supportive care drugs that predispose to reversible posterior leukoencephalopathy syndrome is expanding and includes not only a large number of chemotherapeutic agents but also an increased number of new targeted drugs, particularly angiogenesis inhibitors such as bevacizumab,sorefenib and sunitinib. Pazopanib is an oral tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor, platelet-derived growth factor receptor, and c-Kit which after a positive phase III randomized clinical trial in patients with advanced renal cell cancer received FDA approval for the treatment of advanced renal cell carcinoma. Until now no cases of reversible posterior leukoencephalopathy syndrome induced by pazopanib have been reported. We present the case of a 40 years old female patient with heavily pre-treated metastatic renal cell carcinoma who received pazopanib as salvage treatment. After 21 days of pazopanib therapy the patient referred to the emergency department with epileptic seizure, impaired vision at both eyes and headache. MRI of the brain revealed subcortical oedema at the occipital and parietal lobes bilaterally. She was treated with anticonvulsants, i.v. administration of mannitol and antihypertensives and she recovered completely from her symptoms and was discharged on the tenth hospital day. A brain MRI performed 3 weeks after showed that the subcortical oedema had been subsided. In conclusion this is the first case of pazopanib induced reversible posterior leukoencephalopathy syndrome. Although usually reversible, this syndrome is a serious and potentially life threatening adverse effect, if untreated, that should

    Autoimmune Syndrome Induced by Adjuvant (ASIA) is a definition aimed to describe the common etiological process at the root of five clinical entities sharing similar symptomatology: macrophagic myofasciitis syndrome (MMF), Gulf War Syndrome (GWS), sick building syndrome (SBS), siliconosis, and post vaccination autoimmune phenomena. ASIA illustrates the role of environmental immune stimulating agents, or adjuvants, in the instigation of complex autoimmune reactions among individuals bearing a genetic preponderance for autoimmunity. The value of ASIA lies first in the acknowledgment it provides for patients suffering from these as yet ill-defined medical conditions. Equally important is the spotlight it sheds for further research of these poorly understood conditions sharing a common pathogenesis. In this article we elaborate on the significance of ASIA, review the current evidence in support of the syndrome, and address recent reservations raised regarding its validity.

  20. Improving energy efficiency and smart grid program analysis with agent-based end-use forecasting models

    Jackson, Jerry

    2010-01-01

    Electric utilities and regulators face difficult challenges evaluating new energy efficiency and smart grid programs prompted, in large part, by recent state and federal mandates and financial incentives. It is increasingly difficult to separate electricity use impacts of individual utility programs from the impacts of increasingly stringent appliance and building efficiency standards, increasing electricity prices, appliance manufacturer efficiency improvements, energy program interactions and other factors. This study reviews traditional approaches used to evaluate electric utility energy efficiency and smart-grid programs and presents an agent-based end-use modeling approach that resolves many of the shortcomings of traditional approaches. Data for a representative sample of utility customers in a Midwestern US utility are used to evaluate energy efficiency and smart grid program targets over a fifteen-year horizon. Model analysis indicates that a combination of the two least stringent efficiency and smart grid program scenarios provides peak hour reductions one-third greater than the most stringent smart grid program suggesting that reductions in peak demand requirements are more feasible when both efficiency and smart grid programs are considered together. Suggestions on transitioning from traditional end-use models to agent-based end-use models are provided.

    with promising results. Although these products are in general less expensive than the modern treatments, they can be sensitive to the geographic location and season, and exhibit batch-to-batch variation, which can lead to unexpected allergic reactions, side effects, and contradictory clinical results. Future Directions: The scientific evidence for the use of traditional therapies in wound healing indicates beneficial effects in the treatment of different lesions. However, specific challenges remain unsolved. To extend the efficacy and the usage of natural substances in wound care, multidisciplinary efforts are necessary to prove the safety of these products, investigate their side effects, and develop standard controlled trials. The development of good manufacturing practices and regulatory legislation also assume a pivotal role in order to improve the use of traditional therapies by the clinicians and to promote their integration into the national health system. Current trends move to the development of innovative wound care treatments, combining the use of traditional healing agents and modern products/practices, such as nanofibers containing silver nanoparticles, Aloe vera loaded into alginate hydrogels, propolis into dressing films, and hydrogel sheets containing honey.

    2012-02-01

    We aim to review the clinical features of two renal tubular disorders characterized by sodium and potassium wasting: Bartter syndrome and Gitelman syndrome. Selected key references concerning these syndromes were analyzed, together with a PubMed search of the literature from 2000 to 2011. The clinical features common to both conditions and those which are distinct to each syndrome were presented. The new findings on the genetics of the five types of Bartter syndrome and the discrete mutations in Gitelman syndrome were reviewed, together with the diagnostic workup and treatment for each condition. Patients with Bartter syndrome types 1, 2 and 4 present at a younger age than classic Bartter syndrome type 3. They present with symptoms, often quite severe in the neonatal period. Patients with classic Bartter syndrome type 3 present later in life and may be sporadically asymptomatic or mildly symptomatic. The severe, steady-state hypokalemia in Bartter syndrome and Gitelman syndrome may abruptly become life-threatening under certain aggravating conditions. Clinicians need to be cognizant of such renal tubular disorders, and promptly treat at-risk patients.

Case report. Pediatric intensive care unit of a children's hospital. Ten-month-old with Noonan syndrome and massive gastrointestinal bleeding resulting in severe hypovolemic shock. Recombinant factor VIIa was used in this patient's severe bleeding associated with Noonan syndrome after no other supportive measures were successful. Recombinant Factor VIIa significantly decreased the patient's bleeding and allowed his hypovolemic shock to improve. Ultimately, the patient made a complete recovery. Noonan syndrome has a constellation of both cardiac and noncardiac malformations including an increased risk of bleeding, and recombinant factor VIIa is an important agent in the treatment of significant bleeding.

    Pseudogymnoascus destructans, the causal agent of white-nose syndrome (WNS), is responsible for widespread mortality of hibernating bats across eastern North America. To document P. destructans exposure and infections on bats active during winter in the southeastern US, we collected epidermal swabs from bats captured during winters 2012-13 and 2013-14 in mist nets set outside of hibernacula in Tennessee. Epidermal swab samples were collected from eight Rafinesque's big-eared bats (Corynorhinus rafinesquii), six eastern red bats (Lasiurus borealis), and three silver-hair bats (Lasionycteris noctivagans). Using real-time PCR methods, we identified DNA sequences of P. destructans from skin swabs of two Rafinesque's big-eared bats, two eastern red bats, and one silver-haired bat. This is the first detection of the WNS fungus on Rafinesque's big-eared bats and eastern red bats and the second record of the presence of the fungus on silver-haired bats.

    Full Text Available Background: Wolff-Parkinson-White (WPW syndrome is a disease associated with episodes of supraventricular tachycardia and ventricular pre-excitation or atrial fibrillation. WPW is characterized by an aberrant electrical conduction pathway between atria and ventricles. Case Report: The major anesthetic problem connected with WPW syndrome is the risk of tachyarrhythmias due to accessory pathway. Therefore, it has been proposed that the aim of anesthetic management should be the avoidance of tachyarrhythmia and sympathetic stimulation. Sugammadex was administered as a neuromuscular reversal agent in this case. To our knowledge, this is the first case report of sugammadex use in a patient with WPW. This report presents a case of general anesthesia management in a patient with WPW syndrome. Conclusion: We think that it is appropriate to use sugammadex to reverse rocuronium for the prevention of sudden hemodynamic changes in patients with WPW who underwent general anesthesia.

    In the burning mouth syndrome (BMS), patients experience a burning sensation in the oral cavity with no associated injury or clinical manifestation. The etiology of this condition is still poorly understood, and therefore, treatment is challenging. The aim of this study is to perform a systematic review of treatment possibilities described in the literature for BMS. PubMed, Embase, and SciELO databases were searched for randomized clinical trials published between 1996 and 2016. Following application of inclusion and exclusion criteria, 29 papers were analyzed and divided into five subcategories according to the type of treatment described: antidepressants, alpha-lipoic acid, phytotherapeutic agents, analgesic and anti-inflammatory agents, and non-pharmacological therapies. In each category, the results found were compared with regard to the methodology employed, sample size, assessment method, presence or absence of adverse effects, and treatment outcomes. The analysis revealed that the use of antidepressants and alpha-lipoic acid has been showing promising results; however, more studies are necessary before we can have a first-line treatment strategy for patients with BMS. To review systematically the literature about Burning Mouth Syndrome treatment may aid the clinicians to choose the treatment modality to improve patients symptoms based on the best evidence.

    Classic Bartter syndrome is a salt-wasting tubulopathy caused by mutations in the CLCNKB (chloride channel Kb) gene. Although growth hormone deficiency has been suggested as a cause for persistent growth failure in patients with classic Bartter syndrome, in our opinion the diagnoses of growth hormone deficiency has been unconvincing in some reports. Moreover, Gitelman syndrome seems to have been confused with Bartter syndrome in some cases in the literature. In the present work, we describe a new case with CLCNKB gene mutations and review the reported cases of classic Bartter syndrome associated with growth hormone deficiency. Our patient was a Japanese boy diagnosed as having classic Bartter syndrome at eight months of age. The diagnosis of Bartter syndrome was confirmed by CLCNKB gene analysis, which revealed compound heterozygous mutations with deletion of exons 1 to 3 (derived from his mother) and ΔL130 (derived from his father). His medical therapy consisted of potassium (K), sodium chloride, spironolactone, and anti-inflammatory agents; this regime was started at eight months of age. Our patient was very short (131.1cm, -4.9 standard deviation) at 14.3 years and showed profoundly impaired growth hormone responses to pharmacological stimulants: 0.15μg/L to insulin-induced hypoglycemia and 0.39μg/L to arginine. His growth response to growth hormone therapy was excellent. The present case strengthens the association between classic Bartter syndrome and growth hormone deficiency. We propose that growth hormone status should be considered while treating children with classic Bartter syndrome.

    The metabolic syndrome or cardiovascular dysmetabolic syndrome is characterized by obesity, central obesity, insulin resistance, atherogenic dyslipidemia, and hypertension. The major risk factors leading to this syndrome are physical inactivity and an atherogenic diet and cornerstone clinical feature is abdominal obesity or adiposity. In addition, patients usually have elevated triglycerides, low HDL cholesterol, elevated LDL cholesterol, other abnormal lipid parameters, hypertension, and elevated fasting blood glucose. Impaired fibrinolysis, increased susceptibility to thrombotic events, and raised inflammatory markers are also observed. Given that India has the largest number of subjects with type-2 diabetes in the world it can be extrapolated that this country also has the largest number of patients with the metabolic syndrome. Epidemiological studies confirm a high prevalence. Therapeutic approach involves intervention at a macro-level and control of multiple risk factors using therapeutic lifestyle approaches (diet control and increased physical activity, pharmacotherapy - anti-obesity agents) for control of obesity and visceral obesity, and targeted approach for control of individual risk factors. Pharmacological therapy is a critical step in the management of patients with metabolic syndrome when lifestyle modifications fail to achieve the therapeutic goals. Anti-obesity drugs such as sibutramine and orlistat can be tried to reduce weight and central obesity and jointly control the metabolic syndrome components. Other than weight loss, there is no single best therapy and treatment should consist of treatment of individual components of the metabolic syndrome. Newer drugs such as the endocannabinoid receptor blocker,rimonabant, appear promising in this regard. Atherogenic dyslipidemia should be controlled initially with statins if there is an increase in LDL cholesterol. If there are other lipid abnormalities then combination therapy of statin with fibrates

    Full Text Available In several populations the associations between diet and the risk of metabolic syndrome have not been fully examined yet. The aim of the study is to identify the main dietary patterns among Polish adults and the evaluation of the relationships of these patterns with metabolic syndrome and its components. The study was conducted on a group of 7997 participants, aged between 37 and 66 years old. Dietary patterns were identified by factor analysis. Metabolic syndrome was defined according to the International Diabetes Federation. Three dietary patterns were identified and designated as: “Healthy”, “Westernized” and “Traditional-carbohydrate”. In the adjusted model, a higher score in the “Westernized” pattern aligns with a higher risk of abnormal glucose concentration (ptrend = 0.000, but with a lower risk of abnormal High-Density Lipoprotein Cholesterol HDL-cholesterol concentration (ptrend = 0.024. Higher scores in the “Traditional-carbohydrate” pattern were connected with the risk of abdominal obesity (ptrend = 0.001 and increased triglycerides concentration (ptrend = 0.050. Our results suggest that adherence to the “Traditional-carbohydrate” dietary pattern, characterized by higher intakes of refined grains, potatoes, sugar and sweets is associated with a higher risk of abdominal obesity and triglyceridemia. A “Westernized” dietary pattern on the other hand, is related to hyperglycemia. The study results can be used for community-based health promotion and intervention programs to prevent or better manage chronic diseases.

    Sedative-hypnotic drugs include gamma-Aminobutyric acid (GABA)ergic agents such as benzodiazepines, barbiturates, gamma-Hydroxybutyric acid [GHB], gamma-Butyrolactone [GBL], baclofen, and ethanol. Chronic use of these substances can cause tolerance, and abrupt cessation or a reduction in the quantity of the drug can precipitate a life-threatening withdrawal syndrome. Benzodiazepines, phenobarbital, propofol, and other GABA agonists or analogues can effectively control symptoms of withdrawal from GABAergic agents. Managing withdrawal symptoms requires a patient-specific approach that takes into account the physiologic pathways of the particular drugs used as well as the patient's age and comorbidities. Adjunctive therapies include alpha agonists, beta blockers, anticonvulsants, and antipsychotics. Newer pharmacological therapies offer promise in managing withdrawal symptoms.

    Cerebral hyperperfusion syndrome is a preventable cause of stroke after carotid endarterectomy (CEA). It manifests as headache, seizures, hemiparesis or coma due to raised intracranial pressure or intracerebral haemorrhage (ICH). There is currently no consensus on whether to control blood pressure, blood pressure thresholds associated with cerebral hyperperfusion syndrome, choice of anti-hypertensive agent(s) or duration of treatment. A systematic review of the PubMed database (1963-2010) was performed using appropriate search terms according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 36 studies were identified as fitting a priori inclusion criteria. Following CEA, the incidence of severe hypertension was 19%, that of cerebral hyperperfusion 1% and ICH 0.5%. The postoperative mean systolic blood pressure of patients, who went on to develop cerebral hyperperfusion syndrome, was 164 mmHg (95% confidence interval (CI) 150-178 mmHg) and the cumulative incidence of cases rose appreciably above a postoperative systolic blood pressure of 150 mmHg. The mean systolic blood pressure of cerebral hyperperfusion cases was 189 mmHg (95% CI 183-196 mmHg) at presentation. The incidence of cerebral hyperperfusion in the first week was 92% with a median time to presentation of 5 days (interquartile range (IQR) 3-6 days). 36% of patients presented with seizures 31% with hemiparesis and 33% with both. The proportion of patients with severe hypertension was significantly higher in cases than in post-CEA controls (p hypertension as a risk factor for ICH. There is currently level-3 evidence for the prevention of ICH through control of postoperative blood pressure. From the available data, we suggest a definition for cerebral hyperperfusion syndrome, blood pressure thresholds, duration of monitoring and a postoperative blood pressure control strategy for validation in a prospective study. The implications of this are that one in

    Highlights: • A coordinated multi-agent system is proposed for reactive power management. • A linear quadratic regulator with a proportional integral controller is designed. • Proposed multi-agent scheme provides accurate estimation and control of the system. • Voltage stability is improved with proper power management for different scenarios. • Results obtained from the proposed scheme is compared to the traditional approach. - Abstract: In this paper, a new agent-based distributed reactive power management scheme is proposed to improve the voltage stability of energy distribution systems with distributed generation units. Three types of agents – distribution system agent, estimator agent, and control agent are developed within the multi-agent framework. The agents simultaneously coordinated their activities through the online information and energy flow. The overall achievement of the proposed scheme depends on the coordination between two tasks – (i) estimation of reactive power using voltage variation formula and (ii) necessary control actions to provide the estimated reactive power to the distribution networks through the distributed static synchronous compensators. A linear quadratic regulator with a proportional integrator is designed for the control agent in order to control the reactive component of the current and the DC voltage of the compensators. The performance of the proposed scheme is tested on a 10-bus power distribution network under various scenarios. The effectiveness is validated by comparing the proposed approach to the conventional proportional integral control approach. It is found that, the agent-based scheme provides excellent robust performance under various operating conditions of the power distribution network.

    Full Text Available This paper describes the botanical features of Ficus carica L. (Moraceae, its wide variety of chemical constituents, its use in traditional medicine as remedies for many health problems, and its biological activities. The plant has been used traditionally to treat various ailments such as gastric problems, inflammation, and cancer. Phytochemical studies on the leaves and fruits of the plant have shown that they are rich in phenolics, organic acids, and volatile compounds. However, there is little information on the phytochemicals present in the stem and root. Reports on the biological activities of the plant are mainly on its crude extracts which have been proven to possess many biological activities. Some of the most interesting therapeutic effects include anticancer, hepatoprotective, hypoglycemic, hypolipidemic, and antimicrobial activities. Thus, studies related to identification of the bioactive compounds and correlating them to their biological activities are very useful for further research to explore the potential of F. carica as a source of therapeutic agents.

  1. Alcohols as alkylating agents in heteroarene C–H functionalization

    Jin, Jian; MacMillan, David W. C.

    2015-01-01

    Redox processes and radical intermediates are found in many biochemical processes, including deoxyribonucleotide synthesis and oxidative DNA damage1. One of the core principles that underlies DNA biosynthesis is the radical-mediated elimnation of H2O to deoxygenate ribonucleotides, an example of ‘spin-center shift’ (SCS)2, during which an alcohol C–O bond is cleaved, resulting in a carbon-centered radical intermediate. While SCS is a well-understood biochemical process, it is underutilized by the synthetic organic chemistry community. We wondered whether it would be possible to take advantage of this naturally occurring process to accomplish mild, non-traditional alkylations using alcohols as radical precursors. Considering traditional radical-based alkylation methods require the use of stoichiometric oxidants, elevated temperatures, or peroxides3–7, the development of a mild protocol using simple and abundant alkylating agents would have significant utility in the synthesis of diversely functionalized pharmacophores. In this manuscript, we describe the successful execution of this idea via the development of a dual catalytic alkylation of heteroarenes using alcohols as mild alkylating reagents. This method represents the first broadly applicable use of unactivated alcohols as latent alkylating reagents, achieved via the successful merger of photoredox and hydrogen atom transfer (HAT) catalysis. The utility of this multi-catalytic protocol has been demonstrated through the late-stage functionalization of the medicinal agents, fasudil and milrinone. PMID:26308895

    Full Text Available It is well recognised that the metabolic syndrome, a constellation of risk factors including obesity, hypertension, insulin resistance and dyslipidaemia, is associated with an increased risk of cardiovascular complications and the development of Type 2 diabetes. Consequently, timely identification and management of all components of the metabolic syndrome is warranted. In particular, guidelines have emphasised the importance of targeting elevated blood pressure (BP and dyslipidaemia as a method of reducing global cardiovascular risk.Findings from the Valsartan Antihypertensive Long-term Use Evaluation (VALUE trial show that the angiotensin receptor blocker, valsartan, reduces cardiovascular events and the development of Type 2 diabetes in high-risk individuals. This profile is being further explored in the ongoing Nateglinide And Valsartan in Impaired Glucose Tolerance Outcomes Research (NAVIGATOR trial.Given the potential advantages to patients and physicians of tackling more than one of the components of the metabolic syndrome, antihypertensive agents such as valsartan would appear to be an important addition to the management of vulnerable patients at high risk of cardiovascular events.

    Full Text Available Introduction Guillain-Barre syndrome (GBS is an immune-mediated acute inflammatory disorder of the peripheral nervous system. Infectious agents were usually accused of playing a role in the etiology of GBS. Guillain-Barre syndrome has rarely been reported following subdural and subarachnoid hemorrhage after head trauma. Case Presentation We report on a 63-year-old male patient presenting GBS following Traumatic Brain Injury (TBI. Only five other similar cases are described in the literature. Conclusions Sudden onset of GBS symptoms following trauma may erroneously be assessed as secondary complications of the TBI and can lead to unnecessary procedures such as computerized tomography (CT scan and magnetic resonance imaging (MRI for a definitive diagnosis and may be a waste of time.

    The aim of this study was to determine the metabolic biomarkers for abnormal Savda syndrome in patients with chronic obstructive pulmonary disease (COPD). Based on Traditional Uyghur Medicine (TUM) theory, a total of 103 patients with COPD were classified into abnormal Savda and non-abnormal Savda syndrome groups and 52 healthy volunteers acted as the control group. Blood samples from the three groups were analyzed using nuclear magnetic resonance (NMR) spectroscopy combined with orthogonal projection to latent structure-discriminant analysis. NMR tests showed that the regional distributions of the patients with COPD with abnormal Savda syndrome, those with non-abnormal Savda syndrome and the control group were completely separate (P>0.05). The patients with COPD with abnormal Savda syndrome exhibited relatively low levels of amino acids, glycoproteins and unsaturated lipids (PAbnormal Savda syndrome was one of the main types of syndrome among the patients with COPD; increased age, a longer duration of illness and a higher disease severity were characteristic of this type of syndrome. In addition, the present study provided biochemical evidence for the TUM theory-based classification of patients with COPD; these biomarkers can be used in the clinic for the diagnosis of COPD with abnormal Savda syndrome. The study also demonstrated that the plasma metabolic disorder in patients with COPD with abnormal Savda syndrome was more serious than that in the control and COPD with non-abnormal Savda syndrome groups. The plasma metabolic disorder was also associated with a low immune function of the body and endocrine and energy metabolism disorders.

    Common genetic variation spans schizophrenia, schizoaffective and bipolar disorders, but historically, these syndromes have been distinguished categorically. A symptom dimension shared across these syndromes, if such a general factor exists, might provide a clearer target for understanding and treating mental illnesses that share core biological bases. We tested the hypothesis that a bifactor model of the Positive and Negative Syndrome Scale (PANSS), containing 1 general factor and 5 specific factors (positive, negative, disorganized, excited, anxiety), explains the cross-diagnostic structure of symptoms better than the traditional 5-factor model, and examined the extent to which a general factor reflects the overall severity of symptoms spanning diagnoses in 5094 total patients with a diagnosis of schizophrenia, schizoaffective, and bipolar disorder. The bifactor model provided superior fit across diagnoses, and was closer to the "true" model, compared to the traditional 5-factor model (Vuong test; P schizoaffective, and bipolar disorder. © The Author(s) 2018.

    2011-01-01

    Full Text Available Eugen DhimoleaTufts University School of Medicine, Boston, MA, USAAbstract: Cryopyrin-associated periodic syndrome (CAPS comprises a group of rare, but severe, inherited autoinflammatory disorders associated with aberrant secretion of interleukin (IL-1. These distinct conditions of autoinflammatory origin include Muckle–Wells syndrome, familial cold autoinflammatory syndrome, and neonatal-onset multisystem inflammatory disease (NOMID, which is also referred to as chronic infantile neurologic cutaneous and articular syndrome. Recently, this group of diseases has been associated with mutations in the NLRP3 gene that encodes for the protein cryopyrin, a component of the inflammasome complex that regulates the maturation and secretion of inflammatory cytokine IL-1β. Immune cells from patients with NOMID secrete higher levels of active IL-1β compared with monocytes from healthy subjects. Overproduction of IL-1 is believed to promote aberrant inflammatory response in CAPS patients. Evidence supporting the clinical value of IL-1β in CAPS has been provided from the complete response of patients after treatment with IL-1 blocking agents.Keywords: CAPS, IL-1β, NLRP3, canakinumab, anakinra

    2017-01-01

    Polycystic ovary syndrome (PCOS) is a complex heterogeneous disorder characterized by androgen excess and ovulatory dysfunction; it is now known to be closely linked to metabolic syndrome. Recent research suggests that insulin resistance plays an important role in the pathogenesis of PCOS which may lead to the excessive production of androgens by ovarian theca cells. Currently there is no single drug that can treat both the reproductive and metabolic complications of the disorder. Existing pharmaceutical agents such as hormonal therapies have been associated with side effects and are not appropriate for PCOS women with infertility. Additionally, insulin sensitizing agents useful for treating the metabolic abnormalities in PCOS have limited efficacy for treating reproductive aspects of the disorder. Chinese herbal medicines have a long history of treating gynaecological problems and infertility and therefore may be a novel approach to the treatment of PCOS. Current research demonstrates that the compounds isolated from herbs have shown beneficial effects for PCOS and when combined in an herbal formula can target both reproductive and metabolic defects simultaneously. Therefore, further investigation into Chinese herbal medicine in the treatment of PCOS is warranted.

    Pseudogymnoascus destructans, the causal agent of bat white-nose syndrome, has caused nearly six million deaths in North American bats since its introduction into the United States in 2006. Current research has shown that caves can harbor P. destructans even after the infected bats are removed and bats no longer visit or inhabit previously infected caves. Our research focuses on elucidating reservoir requirements by investigating the nutritional capabilities of and substrate suitability requirements for six different P. destructans isolates from various localities including Illinois, Indiana, New York (Type specimen), and Pennsylvania. Enzyme assays implicate that both urease and b-glucosidase appear to be constitutive, lipase and esterase activity were more rapid than proteinase activity on 6% gelatin, gelatin degradation was accompanied by medium alkalinization, the reduction of thiosulfate generated hydrogen sulfide gas, chitinase and manganese dependent peroxidase activity were not visually demonstrated within eight weeks, and keratinase activity was not evident at pH 8 within eight weeks. We demonstrate that all P. destructans isolates are capable of growth and sporulation on dead fish, insect, and mushroom tissues. Sole nitrogen source assays demonstrated that all P. destructans isolates exhibit Class 2 nitrogen utilization and that growth-dependent interactions occur among different pH and nitrogen sources. Substrate suitability assays demonstrated that all isolates could grow and sporulate on media ranging from pH 5-11 and tolerated media supplemented with 2000 mg/L of calcium and 700 mg/L of three separated sulfur compounds: thiosulfate L-cysteine, and sulfite. All isolates were intolerant to PEG-induced matric potential with delayed germination and growth at -2.5 MPa with no visible germination at -5 MPa. Interestingly, decreasing the surface tension with Tween 80 permitted germination and growth of P. destructans in -5 MPa PEG medium within 14 days

    Equine gastric ulcer syndrome (EGUS) is an umbrella term used to describe ulcers in the nonglandular squamous and glandular mucosa, terminal esophagus, and proximal duodenum. Gastric ulcers in the squamous and glandular regions occur more often than esophageal or duodenal ulcers and likely have a different pathogenesis. At present, omeprazole is accepted globally as the best pharmacologic therapy for both regions of the stomach; however, the addition of coating agents and synthetic prostaglandins could add to its effectiveness in treatment of EGUS. Dietary and environmental management are necessary for prevention of recurrence. Copyright © 2016 Elsevier Inc. All rights reserved.

    Cardiovascular disease is both highly prevalent and exceedingly costly to treat. Several novel antiplatelet agents have been found to be effective in reducing the morbidity and mortality associated with cardiovascular disease. Understanding both the economic and the clinical implications of these novel therapies is particularly important. In this article, the results of published evaluations of the cost-effectiveness of oral antiplatelet strategies for use across a range of clinical conditions and treatment settings are reviewed. The results of these studies support the use of aspirin for primary prevention in high-risk patients and for secondary prevention in all patients with previous cardiovascular events. Although the optimal duration of dual antiplatelet therapy after an event remains uncertain, favorable cost-effectiveness estimates have been demonstrated for aspirin plus clopidogrel versus aspirin alone after a myocardial infarction or percutaneous coronary intervention. Moreover, prasugrel has been shown to be more cost-effective than clopidogrel for patients with an acute coronary syndrome and planned percutaneous coronary intervention. As novel antiplatelet agents emerge and existing agents are tested in different patient populations, the evaluation of the relative economic efficiency of these oral antiplatelet treatment strategies will continue to be instrumental to optimally inform clinical and health-policy decision-making.

  19. Marine Algae as a Potential Source for Anti-Obesity Agents

    Full Text Available Obesity is a major epidemic that poses a worldwide threat to human health, as it is also associated with metabolic syndrome, type 2 diabetes and cardiovascular disease. Therapeutic intervention through weight loss drugs, accompanied by diet and exercise, is one of the options for the treatment and management of obesity. However, the only approved anti-obesity drug currently available in the market is orlistat, a synthetic inhibitor of pancreatic lipase. Other anti-obesity drugs are still being evaluated at different stages of clinical trials, while some have been withdrawn due to their severe adverse effects. Thus, there is a need to look for new anti-obesity agents, especially from biological sources. Marine algae, especially seaweeds are a promising source of anti-obesity agents. Four major bioactive compounds from seaweeds which have the potential as anti-obesity agents are fucoxanthin, alginates, fucoidans and phlorotannins. The anti-obesity effects of such compounds are due to several mechanisms, which include the inhibition of lipid absorption and metabolism (e.g., fucoxanthin and fucoidans, effect on satiety feeling (e.g., alginates, and inhibition of adipocyte differentiation (e.g., fucoxanthin. Further studies, especially testing bioactive compounds in long-term human trials are required before any new anti-obesity drugs based on algal products can be developed.

    Full Text Available The phenomenon that the same syndrome turns up in different diseases appears in the sight of people around the world, which raises the thought for possibility of “Same Treatment for Different Diseases.” Actually, treatment based on ZHENG classification in Traditional Chinese Medicine could bring revelation for the former finding. The dampness-heat syndrome in chronic hepatitis B and nonalcoholic fatty liver is regarded as the breakthrough point. We discussed the molecular mechanism of similar connotation that exists in chronic hepatitis B and nonalcoholic fatty liver by metabonomics to give the modern understanding of dampness-heat syndrome. Both urine and serum metabolic profiling revealed that obvious differences existed between dampness-heat syndrome and non-dampness-heat syndrome but the commonality was proved to appear in chronic hepatitis B and nonalcoholic fatty liver patients with dampness-heat syndrome. Furthermore, disorder of body fluid metabolism, decline in digestive capacity, and imbalance of intestinal flora were found to be the new guiding for treatment, with the hope to provide the basis for Chinese personalized medicine.

  1. Metabolic syndrome: definitions and controversies

    2011-05-01

    Full Text Available Abstract Metabolic syndrome (MetS is a complex disorder defined by a cluster of interconnected factors that increase the risk of cardiovascular atherosclerotic diseases and diabetes mellitus type 2. Currently, several different definitions of MetS exist, causing substantial confusion as to whether they identify the same individuals or represent a surrogate of risk factors. Recently, a number of other factors besides those traditionally used to define MetS that are also linked to the syndrome have been identified. In this review, we critically consider existing definitions and evolving information, and conclude that there is still a need to develop uniform criteria to define MetS, so as to enable comparisons between different studies and to better identify patients at risk. As the application of the MetS model has not been fully validated in children and adolescents as yet, and because of its alarmingly increasing prevalence in this population, we suggest that diagnosis, prevention and treatment in this age group should better focus on established risk factors rather than the diagnosis of MetS.

    Metformin is an oral antidiabetic agent frequently used to manage type II diabetes. This drug produces nonspecific gastrointestinal symptoms in 5-20% of patients and, more rarely, has also been associated with severe adverse effects such as lactic acidosis. Only a few isolated cases of hepatotoxicity due to this drug have been documented. We report the case of an 83-year-old man with constitutional syndrome and hepatic biochemical alterations, which were attributed to metformin after ruling out an oncologic etiology and observing complete clinical and biochemical resolution after withdrawal of the drug.

    We describe a patient with hypothyroidism displaying "dropped head" syndrome. A 50-year-old man visited our clinic because he was unable to hold his head in the natural position. He had weakness and hypertrophy of the neck extensor muscles. Tendon reflexes were diminished or absent in all limbs. Mounding phenomena were observed in the bilateral upper extremities. Blood biochemical analysis revealed hypothyroidism, hyperlipidemia, and elevated levels of muscle-derived enzymes. Magnetic resonance imaging (MRI) of the neck demonstrated swelling and hyperintensity of the neck extensor muscles on T2-weighted images. The result of biopsy of the right biceps brachii muscle suggested mild atrophy of type 2 fibers. The diameters of the muscle fibers exhibited mild variation. No inflammatory changes were observed. We diagnosed hin as having "dropped head" syndrome due to hypothyroidism. Administration of thyroid hormone agent gradually improved his condition, and he became able to hold his head in the natural position. Levels of muscle-derived enzymes normalized and his hyperlipidemia remitted. Neck MRI also revealed improvement. Our findings suggest that hypothyroidism should be considered in the differential diagnosis of "dropped head" syndrome, although only a few cases like ours have been reported.

    Non-prescription slimming products are popular and can be easily purchased from the Internet. However, adulteration of these products with undeclared substances including prescription drugs is not uncommon. We report a case of serotonin syndrome after an overdose of a non-prescription product containing sibutramine. A 21-year-old woman presented with somnolence, sinus tachycardia, generalised increase in tone, hyper-reflexia and clonus more prominent in the lower limbs after an intentional overdose of a non-prescription slimming product obtained from the Internet. The product was later found to contain sibutramine and other substances such as animal thyroid tissues, caffeine and phenolphthalein. Quantitative analysis of patient's serum on presentation revealed a sibutramine concentration of 112 ng/mL, which far exceeded the reported peak serum concentration after a single oral dose of 15 mg (the maximum daily recommended dose). No other culpable agent was identified. The overall clinical presentation was compatible with serotonin syndrome associated with sibutramine overdose. The patient made a full recovery after supportive management. This case highlighted the health threat posed by non-prescription slimming products sold over the Internet. Sibutramine overdose can result in serotonin syndrome, as in overdose of other serotonergic agents. Early recognition and timely supportive treatment are essential to ensure a good clinical outcome.

    To evaluate the current nonpharmacologic and pharmacologic treatment options for symptoms of premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD). Literature was obtained through searches of MEDLINE Ovid (1950-March week 3, 2008) and EMBASE Drugs and Pharmacology (all years), as well as a bibliographic review of articles identified by the searches. Key terms included premenstrual syndrome, premenstrual dysphoric disorder, PMS, PMDD, and treatment. All pertinent clinical trials, retrospective studies, and case reports in human subjects published in the English language were identified and evaluated for the safety and efficacy of pharmacologic and nonpharmacologic treatments of PMS/PMDD. Data from these studies and information from review articles were included in this review. Selective serotonin-reuptake inhibitors (SSRIs) have been proven safe and effective for the treatment of PMDD and are recommended as first-line agents when pharmacotherapy is warranted. Currently fluoxetine, controlled-release paroxetine, and sertraline are the only Food and Drug Administration-approved agents for this indication. Suppression of ovulation using hormonal therapies is an alternative approach to treating PMDD when SSRIs or second-line psychotropic agents are ineffective; however, adverse effects limit their use. Anxiolytics, spironolactone, and nonsteroidal antiinflammatory drugs can be used as supportive care to relieve symptoms. Despite lack of specific evidence, lifestyle modifications and exercise are first-line recommendations for all women with PMS/PMDD and may be all that is needed to treat mild-to-moderate symptoms. Herbal and vitamin supplementation and complementary and alternative medicine have been evaluated for use in PMS/PMDD and have produced unclear or conflicting results. More controlled clinical trials are needed to determine their safety and efficacy and potential for drug interactions. Healthcare providers need to be aware of the symptoms of

    Full Text Available Traditional Chinese medicine (TCM syndrome is an important basis for TCM diagnosis and treatment. As Child-Pugh classification as well as compensation and decompensation phase in liver cirrhosis, it is also an underlying clinical classification. In this paper, we investigated the correlation between single nucleotide polymorphisms (SNPs of Interleukin-10 (IL-10 and TCM syndromes in patients with hepatitis B cirrhosis (HBC. Samples were obtained from 343 HBC patients in China. Three SNPs of IL-10 (−592A/C, −819C/T, and −1082A/G were detected with polymerase chain-reaction-ligase detection reaction (PCR-LDR. The result showed the SNP-819C/T was significantly correlated with Deficiency syndrome (P=0.031, but none of the 3 loci showed correlation either with Child-Pugh classification and phase in HBC patients. The logistic regression analysis showed that the Excess syndrome was associated with dizzy and spider nevus, and the Deficiency syndrome was associated with dry eyes, aversion to cold, IL-10-819C/T loci, and IL-10-1082A/G loci. The odds ratio (OR value at IL-10-819C/T was 4.022. The research results suggested that IL-10-819C/T locus (TC plus CC genotype is probably a risk factor in the occurrence of Deficiency syndrome in HBC patients.

    Full Text Available Elaeagnus angustifolia L., which is commonly known as oleaster or Russian olive, is a deciduous plant from Elaeagnacea family. This plant can tolerate and survive a wide variety of environmental conditions. Different parts of E. angustifolia plant, especially the fruits and flowers, have been used traditionally in treating a variety of common illnesses such as nausea, cough, asthma, fever, jaundice, and diarrhea. The use of fruit powder and extract of E. angustifolia L. have shown to be effective in alleviating pain in patients with rheumatoid arthritis and also in reducing the healing time of wounds in injured person. In addition, some recent reports have indicated the anti-oxidant, anti-inflammatory, antimicrobial, anticancer and some other properties of oleaster plant. The other important property of this plant would be its role in bio-monitoring the environment for some toxic elements and also its action as a bio-fertilizer agent in distressed lands. It seems that with more advanced studies on E. angustifolia L. and its bioactive components, this plant might be potentially effective and can be used as a natural alternative resource in pharmaceutical industries for treating chronic and serious problems, Fig. 1.

  11. A clinical perspective of obesity, metabolic syndrome and cardiovascular disease

    2016-02-01

    Full Text Available The metabolic syndrome is a condition characterized by a special constellation of reversible major risk factors for cardiovascular disease and type 2 diabetes. The main, diagnostic, components are reduced HDL-cholesterol, raised triglycerides, blood pressure and fasting plasma glucose, all of which are related to weight gain, specifically intra-abdominal/ectopic fat accumulation and a large waist circumference. Using internationally adopted arbitrary cut-off values for waist circumference, having metabolic syndrome doubles the risk of cardiovascular disease, but offers an effective treatment approach through weight management. Metabolic syndrome now affects 30–40% of people by age 65, driven mainly by adult weight gain, and by a genetic or epigenetic predisposition to intra-abdominal/ectopic fat accumulation related to poor intra-uterine growth. Metabolic syndrome is also promoted by a lack of subcutaneous adipose tissue, low skeletal muscle mass and anti-retroviral drugs. Reducing weight by 5–10%, by diet and exercise, with or without, anti-obesity drugs, substantially lowers all metabolic syndrome components, and risk of type 2 diabetes and cardiovascular disease. Other cardiovascular disease risk factors such as smoking should be corrected as a priority. Anti-diabetic agents which improve insulin resistance and reduce blood pressure, lipids and weight should be preferred for diabetic patients with metabolic syndrome. Bariatric surgery offers an alternative treatment for those with BMI ≥ 40 or 35–40 kg/m 2 with other significant co-morbidity. The prevalence of the metabolic syndrome and cardiovascular disease is expected to rise along with the global obesity epidemic: greater emphasis should be given to effective early weight-management to reduce risk in pre-symptomatic individuals with large waists.

    Full Text Available Abstract Anti-platelet therapy plays an important role in the treatment of patients with thrombotic diseases. The most commonly used anti-platelet drugs, namely, aspirin, ticlopidine, and clopidogrel, are effective in the prevention and treatment of cardio-cerebrovascular diseases. Glycoprotein IIb/IIIa antagonists (e.g., abciximab, eptifibatide and tirofiban have demonstrated good clinical benefits and safety profiles in decreasing ischemic events in acute coronary syndrome. However, adverse events related to thrombosis or bleeding have been reported in cases of therapy with glycoprotein IIb/IIIa antagonists. Cilostazol is an anti-platelet agent used in the treatment of patients with peripheral ischemia, such as intermittent claudication. Presently, platelet adenosine diphosphate P2Y(12 receptor antagonists (e.g., clopidogrel, prasugrel, cangrelor, and ticagrelor are being used in clinical settings for their pronounced protective effects. The new protease-activated receptor antagonists, vorapaxar and atopaxar, potentially decrease the risk of ischemic events without significantly increasing the rate of bleeding. Some other new anti-platelet drugs undergoing clinical trials have also been introduced. Indeed, the number of new anti-platelet drugs is increasing. Consequently, the efficacy of these anti-platelet agents in actual patients warrants scrutiny, especially in terms of the hemorrhagic risks. Hopefully, new selective platelet inhibitors with high anti-thrombotic efficiencies and low hemorrhagic side effects can be developed.

    Several cases of toxic shock syndrome (T.S.S) have been recently reported from the U.S.A. Clinical features of this new syndrome include fever, desquamative scarlatiniform rash, hypotension and involvement of central nervous system, liver, kidney and muscles. More than 90% of cases are women with staphylococcic vaginitis using tampons during menstruations. A toxin produced by staphylococcus aureus is thought to be the causative agent, because the germ has been isolated in local (vaginal, pharyngeal, subcutaneous or other sites) but not systemic (blood, cerebrospinal fluid) cultures. The mortality rate is 3-10%, and relapse can occur. We report the first three french cases of T.S.S.: a 17 year old girl with typical tampon-associated vaginitis, a 36 year old woman with a postoperative peritonitis and a 20 year old man with a popliteal abscess. Staphylococcus aureus of type I or IV was identified at the site of infection in all cases, but never in blood cultures. These three patients recovered with antistaphylococcic antibiotics and supportive therapy, but local treatment of infections seems to have been of utmost importance. These cases suggest that T.S.S. can occur with several staphylococcus serotypes and confirm that this syndrome is not always associated with tampons and vaginitis.

    Marriage is a container for framing the inner-to-heart relationship, the bond of love and affection between a man and woman to nurture a joy of happiness. This study aims to find out how the process and stages in traditional merariq traditions in the Sasak people, conflicts arising from merariq traditions, and reduce conflict through the tradition of selabar. The method used in this research is qualitative analysis method. In the process, merariq tradition is done by kidnapping the bride without the knowledge of the parents or the family of the women. There are several stages that must be passed by the bride and groom in the tradition merariq, namely: besejati, nyelabar, bait wali, sorong serah dan nyongkolang. Conflict that often arises, for internal family, merariq often become a place of coercion against the female family. For society, merariq impact on disruption of harmony of social life. In order to reduce the conflicts done selabar tradition, the tragedy is regarded as an alternative problem solving in the form of negotiations between the bride and groom’s family and the bride-to-be relating to ajikrame and pisuke transactions.

    2009-01-01

    The design of the control systems for sensor networks presents important challenges. Besides the traditional problems about how to process the sensor data to obtain the target information, engineers need to consider additional aspects such as the heterogeneity and high number of sensors, and the flexibility of these networks regarding topologies and the sensors in them. Although there are partial approaches for resolving these issues, their integration relies on ad hoc solutions requiring important development efforts. In order to provide an effective approach for this integration, this paper proposes an architecture based on the multi-agent system paradigm with a clear separation of concerns. The architecture considers sensors as devices used by an upper layer of manager agents. These agents are able to communicate and negotiate services to achieve the required functionality. Activities are organized according to roles related with the different aspects to integrate, mainly sensor management, data processing, communication and adaptation to changes in the available devices and their capabilities. This organization largely isolates and decouples the data management from the changing network, while encouraging reuse of solutions. The use of the architecture is facilitated by a specific modelling language developed through metamodelling. A case study concerning a generic distributed system for fire fighting illustrates the approach and the comparison with related work.

    2010-06-01

    Hyponatraemia is the commonest electrolyte abnormality, and syndrome of inappropriate antidiuretic hormone (SIADH) is the most frequent underlying pathophysiology. Hyponatraemia is associated with significant morbidity and mortality, and as such appropriate treatment is essential. Treatment options for SIADH include fluid restriction, demeclocycline, urea, frusemide and saline infusion, all of which have their limitations. The introduction of the vasopressin-2 receptor antagonists has allowed clinicians to specifically target the underlying pathophysiology of SIADH. Initial studies have shown good efficacy and safety profiles in the treatment of mild to moderate hyponatraemia. However, studies assessing the efficacy and safety of these agents in acute severe symptomatic hyponatraemia are awaited. Furthermore, the cost of these agents at present may limit their use.

    Full Text Available Antiphospholipid syndrome (APS is an autoimmune disease characterised by arterial and/or venous thrombosis, recurrent pregnancy loss, and persistently positive antiphospholipid antibodies (aPLs. It could be life-threatening as in the case of catastrophic APS where multi-organ failure is observed. APS morbidities are thought to be the result of a combination of thrombotic and inflammatory processes. Over the past decades, the mainstay of therapy of APS has been anticoagulation. As new mechanisms of pathogenesis are being unravelled with time, novel targeted immunomodulatory therapies are being proposed as promising agents in the treatment of APS. In this article, we present an overview of new pathogenetic mechanisms in APS as well as novel antithrombotic and immunomodulatory therapies.

    Sensorial materials consisting of high-density, miniaturized, and embedded sensor networks require new robust and reliable data processing and communication approaches. Structural health monitoring is one major field of application for sensorial materials. Each sensor node provides some kind of sensor, electronics, data processing, and communication with a strong focus on microchip-level implementation to meet the goals of miniaturization and low-power energy environments, a prerequisite for autonomous behaviour and operation. Reliability requires robustness of the entire system in the presence of node, link, data processing, and communication failures. Interaction between nodes is required to manage and distribute information. One common interaction model is the mobile agent. An agent approach provides stronger autonomy than a traditional object or remote-procedure-call based approach. Agents can decide for themselves, which actions are performed, and they are capable of flexible behaviour, reacting on the environment and other agents, providing some degree of robustness. Traditionally multi-agent systems are abstract programming models which are implemented in software and executed on program controlled computer architectures. This approach does not well scale to micro-chip level and requires full equipped computers and communication structures, and the hardware architecture does not consider and reflect the requirements for agent processing and interaction. We propose and demonstrate a novel design paradigm for reliable distributed data processing systems and a synthesis methodology and framework for multi-agent systems implementable entirely on microchip-level with resource and power constrained digital logic supporting Agent-On-Chip architectures (AoC). The agent behaviour and mobility is fully integrated on the micro-chip using pipelined communicating processes implemented with finite-state machines and register-transfer logic. The agent behaviour

    Full Text Available Currently, the goal of treatment for those with irritable bowel syndrome (IBS is to improve the quality of life through a reduction in symptoms. While the majority of treatment approaches involve the use of traditional medicine, more and more patients seek out a non-drug approach to managing their symptoms. Current forms of non-drug psychologic or mind/body treatment for IBS include hypnotherapy, cognitive behavioral therapy and brief psychodynamic psychotherapy, all of which have been proven efficacious in clinical trials. We propose that incorporating the constructs of mindfulness and acceptance into a mind/body psychologic treatment of IBS may be of added benefit due to the focus on changing awareness and acceptance of one's own state which is a strong component of traditional and Eastern healing philosophies.

    Full Text Available This study assessed the risk of developing acute coronary syndrome requiring hospitalization in association with the use of certain antipsychotic medications in schizophrenia patients.A nationwide cohort of 31,177 inpatients with schizophrenia between the ages of 18 and 65 years whose records were enrolled in the National Health Insurance Research Database in Taiwan from 2000 to 2008 and were studied after encrypting the identifications. Cases (n = 147 were patients with subsequent acute coronary syndrome requiring hospitalization after their first psychiatric admission. Based on a nested case-control design, each case was matched with 20 controls for age, sex and the year of first psychiatric admission using risk-set sampling. The effects of antipsychotic agents on the development of acute coronary syndrome were assessed using multiple conditional logistic regression and sensitivity analyses to confirm any association.We found that current use of aripiprazole (adjusted risk ratio [RR] = 3.68, 95% CI: 1.27-10.64, p<0.05 and chlorpromazine (adjusted RR = 2.96, 95% CI: 1.40-6.24, p<0.001 were associated with a dose-dependent increase in the risk of developing acute coronary syndrome. Although haloperidol was associated with an increased risk (adjusted RR = 2.03, 95% CI: 1.20-3.44, p<0.01, there was no clear dose-dependent relationship. These three antipsychotic agents were also associated with an increased risk in the first 30 days of use, and the risk decreased as the duration of therapy increased. Sensitivity analyses using propensity score-adjusted modeling showed that the results were similar to those of multiple regression analysis.Patients with schizophrenia who received aripiprazole, chlorpromazine, or haloperidol could have a potentially elevated risk of developing acute coronary syndrome, particularly at the start of therapy.

    The aim of this study was to investigate the developmental trajectories of verbal aggression, physical aggression, and temper tantrums in four genetic syndrome groups. Participants were part of the Australian Child to Adult Development Study (ACAD), which collected information from a cohort of individuals with an intellectual disability at five time points over 18 years. Data were examined from a total of 248 people with one of the four following syndromes: Down syndrome, Fragile X syndrome, Prader-Willi syndrome, or Williams syndrome. Changes in behaviors were measured using validated items from the Developmental Behavior Checklist (DBC). The results indicate that, while verbal aggression shows no evidence of diminishing with age, physical aggression, and temper tantrums decline with age before 19 years for people with Down syndrome, Fragile X syndrome, and William syndrome; and after 19 years for people with Prader-Willi syndrome. These findings offer a somewhat more optimistic outlook for people with an intellectual disability than has previously been suggested. Research is needed to investigate the mechanisms predisposing people with PWS to persistence of temper tantrums and physical aggression into adulthood. © 2015 Wiley Periodicals, Inc.

    Increasing environmental awareness and emerging trends such as water trading, energy market, deregulation and democratization of water-related services are challenging integrated water resources planning and management worldwide. The traditional approach to water management design based on sector-by-sector optimization has to be reshaped to account for multiple interrelated decision-makers and many stakeholders with increasing decision power. Centralized management, though interesting from a conceptual point of view, is unfeasible in most of the modern social and institutional contexts, and often economically inefficient. Coordinated management, where different actors interact within a full open trust exchange paradigm under some institutional supervision is a promising alternative to the ideal centralized solution and the actual uncoordinated practices. This is a significant issue in most of the Southern Alps regulated lakes, where upstream hydropower reservoirs maximize their benefit independently form downstream users; it becomes even more relevant in the case of transboundary systems, where water management upstream affects water availability downstream (e.g. the River Zambesi flowing through Zambia, Zimbabwe and Mozambique or the Red River flowing from South-Western China through Northern Vietnam. In this study we apply Multi-Agent Systems (MAS) theory to design an optimal management in a decentralized way, considering a set of multiple autonomous agents acting in the same environment and taking into account the pay-off of individual water users, which are inherently distributed along the river and need to coordinate to jointly reach their objectives. In this way each real-world actor, representing the decision-making entity (e.g. the operator of a reservoir or a diversion dam) can be represented one-to-one by a computer agent, defined as a computer system that is situated in some environment and that is capable of autonomous action in this environment in

    Full Text Available Maintenance of gestation implicates complex function of multiple endocrine mechanisms, and disruptions of the global metabolic environment prompt profound consequences on fetomaternal well-being during pregnancy and postpartum. Polycystic Ovary Syndrome (PCOS and gestational diabetes mellitus (GDM are very frequent conditions which increase risk for pregnancy complications, including early pregnancy loss, pregnancy-induced hypertensive disorders, and preterm labor, among many others. Insulin resistance (IR plays a pivotal role in the pathogenesis of both PCOS and GDM, representing an important therapeutic target, with metformin being the most widely prescribed insulin-sensitizing antidiabetic drug. Although traditional views neglect use of oral antidiabetic agents during pregnancy, increasing evidence of safety during gestation has led to metformin now being recognized as a valuable tool in prevention of IR-related pregnancy complications and management of GDM. Metformin has been demonstrated to reduce rates of early pregnancy loss and onset of GDM in women with PCOS, and it appears to offer better metabolic control than insulin and other oral antidiabetic drugs during pregnancy. This review aims to summarize key aspects of current evidence concerning molecular and epidemiological knowledge on metformin use during pregnancy in the setting of PCOS and GDM.

    The WHO held an Expert Committee Meeting in Botswana to identify ways by which traditional health practitioners might contribute to AIDS prevention and treatment. Medium Term Plans for AIDS control in Botswana, Kenya, Zimbabwe, Tanzania and Uganda have already defined areas of community-based care, counseling and symptomatic treatment appropriate for traditional healers. Traditional healers and midwives often play central roles in maintenance of social stability, provide valuable information on sexual behavior, teach young people about sexual roles, and act as informal networks for women, especially in Islamic communities. Many indigenous concepts on the cause and transmission of HIV/AIDS are compatible with modern scientific concepts, although expressed in different terms and conceptual frameworks. AIDS is often considered an indigenous disease, caused by contact of blood and semen, therefore treatable by indigenous methods. In their role as informal community leaders and guardians of social norms, healers and midwives can channel educational messages and act as change agents. Healers can convey technically appropriate home care, dispense symptomatic care, treat opportunistic infections and counsel young people about control of HIV.

    2003-11-01

    Full Text Available Abstract Polycystic ovary syndrome [PCOS] is the commonest cause of anovulatory infertility. Treatment modes available are numerous mainly relying on ovarian stimulation with FSH, a reduction in insulin concentrations and a decrease in LH levels as the basis of the therapeutic principles. Clomiphene citrate is still the first line treatment and if unsuccessful is usually followed by direct FSH stimulation. This should be given in a low dose protocol, essential to avoid the otherwise prevalent complications of ovarian hyperstimulation syndrome and multiple pregnancies. The addition of a GnRH agonists, while very useful during IVF/ET, adds little to ovulation induction success whereas the position of GnRH antagonists is not yet clear. Hyperinsulinemia is the commonest contributor to the state of anovulation and its reduction, by weight loss or insulin sensitizing agents such as metformin, will alone often restore ovulation or will improve results when used in combination with other agents. Laparoscopic ovarian drilling is proving equally as successful as FSH for the induction of ovulation, particularly in thin patients with high LH concentrations. Aromatase inhibitors are presently being examined and may replace clomiphene in the future. When all else has failed, IVF/ET produces excellent results. In conclusion, there are very few women suffering from anovulatory infertility associated with PCOS who cannot be successfully treated today.

    Full Text Available Kipo is a traditional food from Kotagede Region – Yogyakarta, which is produced from glutinous rice. It was processed through some steps such as weighing, mixing, melting, roasting and packing. This traditional food is not popular like other traditional foods such as gudeg or yangko. Problems concerning this situation were, the information of kipo was not well delivered to the consumers and people who were doing business with kipo were very limited and only in Kotagede.This research was aimed to disclosure the potency of kipo, if it was developed as industrial foods. The aspects of market, technical and financial were conducted and analyzed. These aspects were used for giving considerations, if this product could be developed in the future. The results depicted, that from the market aspect, value kipoconsumer’s attitude index was good (3.8845 from 5. The technical aspect showed, that this industry was quite small scale with processing capacity only 19 kg product per day, used 5 menpower and 60 m2 area.Based on the financial aspect at actual capacity, the results showed Net Present Value was Rp. 70,180,679; Payback Period 1.21 years; Profitability Index 5.51;Internal Rate of Return 98.5% and Break Even Point was Rp. 505,414 or 212,693 kipo. This industry was very sensitive to the increase of interest level, total cost and decrease of price product. Some challenged aspects of kipo were, it was produced from naural sources such as glutinous rice, coconut, brown sugar and also natural food colouring agent. The traditional process was still kept and the people could enjoy how it was produced. This is the challenge to develop the traditional food as part of culinary or historical tour.

    In most economics--driven approaches to optimizing water use at the river basin scale, the system is modelled deterministically with the goal of maximizing overall benefits. However, actual operation and allocation decisions must be made under hydrologic and economic uncertainty. In addition, river basins often cross political boundaries, and different states may not be motivated to cooperate so as to maximize basin- scale benefits. Even within states, competing agents such as irrigation districts, municipal water agencies, and large industrial users may not have incentives to cooperate to realize efficiency gains identified in basin- level studies. More traditional simulation--optimization approaches assume pre-commitment by individual agents and stakeholders and unconditional compliance on each side. While this can help determine attainable gains and tradeoffs from efficient management, such hardwired policies do not account for dynamic feedback between agents themselves or between agents and their environments (e.g. due to climate change etc.). In reality however, we are dealing with an out-of-equilibrium multi-agent system, where there is neither global knowledge nor global control, but rather continuous strategic interaction between decision making agents. Based on the theory of stochastic games, we present a computational framework that allows for studying the dynamic feedback between decision--making agents themselves and an inherently uncertain environment in a spatially and temporally distributed manner. Agents with decision-making control over water allocation such as countries, irrigation districts, and municipalities are represented by reinforcement learning agents and coupled to a detailed hydrologic--economic model. This approach emphasizes learning by agents from their continuous interaction with other agents and the environment. It provides a convenient framework for the solution of the problem of dynamic decision-making in a mixed cooperative / non

    2017-03-01

    The present research examines the influence of intuitive cognitive domain and religion on the God concepts of children growing up in religious traditions that present God in ways varying from abstract to concrete. In Study 1, we compared children from a Latter-Day Saints (LDS) background with those from mainstream Christian (MC) backgrounds in the United States. In contrast to MC theology that holds that God is all-knowing, all-powerful, and disembodied, LDS theology depicts God as embodied. In Study 1, 3- to 7-year-olds from LDS and MC backgrounds were asked about supernatural mental and immaterial attributes of God, a ghost, a dad, and a bug. In Study 2, children ages 3-7 from Muslim and Catholic backgrounds in Indonesia were presented with a variant of Study 1. Taken together, the two studies examine the God concepts of children raised in three different religious traditions with God concepts that range from highly abstract to concrete. Overall, we find that the youngest children, regardless of religion, distinguish God from humans and hold similar ideas of God, attributing more supernatural psychological than physical properties. Older children's conceptions of God are more in line with the theological notions of their traditions. The results suggest that children are not simply anthropomorphic in their God concepts, but early on understand supernatural agents as having special mental properties and they continue to learn about differences between agents, influenced by their religious traditions. Statement of contribution What is already known on this subject Research on children's God concepts has established that children begin to distinguish the mind of God from that of humans by around age 4-5. The main debate in the field is whether children start out thinking about God in anthropomorphic terms or whether they start out with an undifferentiated idea of agents' minds as all having access to knowledge. Research on children's understanding of immortality has

    With the approval of mechlorethamine by the FDA in 1949 for the treatment of hematologic malignancies, alkylating agents are the oldest class of anticancer agents. Even though their clinical use is far beyond the use of new targeted therapies, they still occupy a major place in specific indications and sometimes represent the unique option for the treatment of refractory diseases. Here, we are reviewing the major classes of alkylating agents and their mechanism of action, with a particular emphasis for the new generations of alkylating agents. As for most of the chemotherapeutic agents used in the clinic, these compounds are derived from natural sources. With a complex but original mechanism of action, they represent new interesting alternatives for the clinicians, especially for tumors that are resistant to conventional DNA damaging agents. We also briefly describe the different strategies that have been or are currently developed to potentiate the use of classical alkylating agents, especially the inhibition of pathways that are involved in the repair of DNA lesions induced by these agents. In this line, the development of PARP inhibitors is a striking example of the recent regain of interest towards the "old" alkylating agents.

    2010-05-01

    Full Text Available Abstract Introduction Traditional management of Gradenigo's syndrome requires aggressive and radical surgery without any attempt to preserve hearing. Recent reports, however, describe a successful outcome after conservative surgical intervention without labyrinthectomy. A similar outcome has also been reported in patients who were only prescribed with antibiotics and did not undergo myringotomy. Case presentation We report the case of a 24-year-old Caucasian Greek woman with Gradenigo's syndrome who was treated by draining her petrous apex via an infralabyrithine approach between her posterior semicircular canal and the jugular bulb. Her inner ear was not sacrificed during the procedure. She presented pre-operatively with ipsilateral conductive hearing loss, which recovered completely four weeks after the surgery. Conclusions Patients with Gradenigo's syndrome may be successfully treated with a combination of long-term permanent drainage and ventilation of the apical cells with corresponding hearing preservation. This can be achieved via a combination of transmastoid, infralabyrinthine and suprajugular approaches, if such would be allowed by the anatomy of the region or if there is enough space between the posterior semicircular canal and the jugular bulb.

    If there were a stigma scale for chemotherapy, alkylating agents would be ranked at the top of the list. The chemical term alkylation is associated with nonselective toxicity, an association that dates back to the use of nitrogen mustards during World War I as chemical warfare agents. That this stigma persists and extends to compounds that, through selectivity, attempt to “tame” the indiscriminate destructive potential of alkylation is the subject of this review. Selective alkylation, as it is referred to herein, constitutes an extremely nascent and dynamic field in oncology. The pharmacodynamic response to this selective strategy depends on a delicate kinetic balance between specificity and the rate and extent of binding. Three representative compounds are presented: RRx-001, 3-bromopyruvate, and TH-302. The main impetus for the development of these compounds has been the avoidance of the serious complications of traditional alkylating agents; therefore, it is the thesis of this review that they should not experience stigma by association.

    Full Text Available A multi-agent based fleet maintenance personnel configuration method is proposed to solve the mission oriented aircraft fleet maintenance personnel configuration problem. The maintenance process of an aircraft fleet is analyzed first. In the process each aircraft contains multiple parts, and different parts are repaired by personnel with different majors and levels. The factors and their relationship involved in the process of maintenance are analyzed and discussed. Then the whole maintenance process is described as a 3-layer multi-agent system (MAS model. A communication and reasoning strategy among the agents is put forward. A fleet maintenance personnel configuration algorithm is proposed based on contract net protocol (CNP. Finally, a fleet of 10 aircraft is studied for verification purposes. A mission type with 3 waves of continuous dispatch is imaged. Compared with the traditional methods that can just provide configuration results, the proposed method can provide optimal maintenance strategies as well.

    MINI: Fourteen hundred consecutive patients were investigated for evaluating the utility of waterless hand rub before orthopaedic surgery. The risk in the surgical site infection incidence was the same, but costs of liquids used for hand hygiene were cheaper and the hand hygiene time was shorter for waterless protocol, compared with traditional hand scrub. A retrospective cohort study with prospectively collected data. The aim of this study was to compare SSI incidences, the cost of hand hygiene agents, and hand hygiene time between the traditional hand scrub and the waterless hand rub protocols before orthopedic surgery. Surgical site infections (SSI) prolong hospitalization and are a leading nosocomial cause of morbidity and a source of excess cost. Recently, a waterless hand rub protocol comprising alcohol based chlorhexidine gluconate for use before surgery was developed, but no studies have yet examined its utility in orthopedic surgery. Fourteen hundred consecutive patients who underwent orthopedic surgery (spine, joint replacement, hand, and trauma surgeries) in our hospital since April 1, 2012 were included. A total of 712 cases underwent following traditional hand scrub between April 1, 2012 and April 30, 2013 and 688 cases underwent following waterless hand rub between June 1, 2013 and April 30, 2014. We compared SSI incidences within all and each subcategory between two hand hygiene protocols. All patients were screened for SSI within 1 year after surgery. We compared the cost of hand hygiene agents and hand hygiene time between two groups. The SSI incidences were 1.3% (9 of 712) following the traditional protocol (2 deep and 7 superficial infections) and 1.1% (8 of 688) following the waterless protocol (all superficial infections). There were no significant differences between the two groups. The costs of liquids used for one hand hygiene were about $2 for traditional hand scrub and less than $1 for waterless hand rub. The mean hand hygiene time was 264

    Hungarian physicist Dennis Gabor won the Pulitzer Prize for his 1947 introduction of basic holographic principles, but it was not until the invention of the laser in 1960 that research scientists, physicians, technologists and the general public began to seriously consider the interdisciplinary potentiality of holography. Questions around whether and when Three-Dimensional (3-D) images and systems would impact American entertainment and the arts would be answered before educators, instructional designers and students would discover how much Three-Dimensional Hologram Technology (3DHT) would affect teaching practices and learning environments. In the following International Symposium on Display Holograms (ISDH) poster presentation, the author features a traditional board game as well as a reflection hologram to illustrate conventional and evolving Three-Dimensional representations and technology for education. Using elements from the American children's toy Operation® (Hasbro, 2005) as well as a reflection hologram of a human brain (Ko, 1998), this poster design highlights the pedagogical effects of 3-D images, games and systems on learning science. As teaching agents, holograms can be considered substitutes for real objects, (human beings, organs, and animated characters) as well as agents (pedagogical, avatars, reflective) in various learning environments using many systems (direct, emergent, augmented reality) and electronic tools (cellphones, computers, tablets, television). In order to understand the particular importance of utilizing holography in school, clinical and public settings, the author identifies advantages and benefits of using 3-D images and technology as instructional tools.

    Full Text Available In traditional Chinese medicine (TCM, correct syndrome differentiation is the most important principle guiding the prescription of Chinese herbal formulae for the treatment of gastric cancer (GC. We aimed to reveal the genetic mechanisms underlying GC syndrome differentiation (ZHENG in a population of 387 GC patients. Twenty-nine single nucleotide polymorphisms (SNPs in EGF, TGFA, and EGFR were investigated. Two SNPs, rs11466285 in TGFA and rs884225 in EGFR, were significantly associated with the distribution of ZHENG (P<0.05. The rs11466285 TT genotype increased the risk of damp heat with toxin (DHT and deficiency of both Qi and yin (DQY compared with obstruction of blood stasis (OBS. The rs884225 AA genotype could increase the risk of DQY and deficiency of both Qi and blood (DQB compared with yin deficiency due to stomach heat (YDSH. Parallel comparison among the SNPs and syndrome types revealed that DQB was distinct from YDSH, disharmony between the liver and stomach, stagnation of phlegm muddiness (SPM, OBS, and other syndromes at several SNP loci (P<0.05. The rs11466285 TT and rs884225 AA genotypes exhibit increased risk of DQB compared with OBS and SPM (P<0.05, respectively. In conclusion, the formation of GC ZHENG was related to EGF, TGFA, and EGFR gene polymorphisms.

    Gorlin-Goltz syndrome is an uncommon hereditary condition caused by mutations in the PTCH1 gene causing a wide range of developmental abnormalities. Multiple basal cell carcinomas, palmoplantar pits and jaw cysts are cardinal features. Many clinicians are unfamiliar with the different manifestations and the fact that patients are especially sensitive to ionizing radiation. This was a retrospective analysis of patients with Gorlin-Goltz syndrome seen at the Department of Dermatology and Allergy Centre or at Department of Plastic Surgery, Odense University Hospital, Denmark, in the period from 1994 to 2013. A total of 17 patients from eight families fulfilled the diagnostic criteria. In all, 14 patients had basal cell carcinomas, 12 patients had jaw cysts and ten patients had calcification of the falx cerebri. Other clinical features were frontal bossing, kyphoscoliosis, rib anomalies, coalitio, cleft lip/palate, eye anomalies, milia and syndactyly. In one family, medulloblastoma and astrocytoma occurred. Traditional treatment principles of basal cell carcinomas were used including radiotherapy performed in six patients. PTCH1 mutations were identified in five families and none of these mutations had previously been described. The patient cohort illustrates classic and rare disease manifestations. It is necessary to remind clinicians that radiation therapy in Gorlin-Goltz syndrome is relatively contraindicated. Today, mutation analysis can be used for confirmation of the diagnosis and for predictive genetic testing. Patients should be offered genetic counselling and life-long surveillance. not relevant. not relevant.

    Topical medicinal patches have been popular for the treatment of minor injuries like sprains and avulsions. Other inflammatory conditions like chronic musculo-tendinous pain and or fasciitis are also taken care of by local ointments or rubs. In the oriental communities, medicinal herbs frequently form the major components of the patches. In spite of the lack of scientific evidence of efficacy, the popularity of such traditional application persists for centuries. In this era of evidence-based...

    Abstract Background: Chronic kidney disease (CKD) and metabolic syndrome are characterized by overlapping disorders, including glucose intolerance, hypertension, dyslipidemia, and, in some cases, obesity. However, there are no specific criteria for the diagnosis of metabolic syndrome in CKD. Metabolic syndrome can also be associated with increased risk of mortality. Some traditional risk factors may protect dialysis patients from mortality, known as "reverse epidemiology." Metabolic syndrome might undergo reverse epidemiology. The objectives were to detect differences in frequency and metabolic characteristics associated with three sets of diagnostic criteria for metabolic syndrome, to evaluate the accuracy of insulin resistance (IR) and inflammation to identify patients with metabolic syndrome, and to investigate the effects of metabolic syndrome by three sets of diagnostic criteria on mortality in chronic hemodialysis patients. An observational study was conducted. Diagnostic criteria for metabolic syndrome proposed by National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III), International Diabetes Federation (IDF), and Harmonizing the Metabolic Syndrome (HMetS) statement were applied to 98 hemodialysis patients. The prevalence of metabolic syndrome was 51%, 66.3%, and 75.3% according to NCEP ATP III, IDF, and HMetS criteria, respectively. Diagnosis of metabolic syndrome by HMetS was simultaneously capable of revealing both inflammation and IR, whereas NCEP ATP III and IDF criteria were only able to identify IR. Mortality risk increased in the presence of metabolic syndrome regardless of the criteria used. The prevalence of metabolic syndrome in hemodialysis varies according to the diagnostic criteria used. IR and inflammation predict metabolic syndrome only when diagnosed by HMetS criteria. HMetS was the diagnostic criteria that can predict the highest risk of mortality.

    Abstract Background The neuroleptic malignant syndrome is an uncommon but dangerous complication characterized by hyperthermia, autonomic dysfunction, altered mental state, hemodynamic dysregulation, elevated serum creatine kinase, and rigor. It is most often caused by an adverse reaction to anti-psychotic drugs or abrupt discontinuation of neuroleptic or anti-parkinsonian agents. To the best of our knowledge, it has never been reported following the common practice of discontinuation of anti...

    Male reproductive tract abnormalities such as hypospadias and cryptorchidism, and testicular cancer have been proposed to comprise a common syndrome together with impaired spermatogenesis with a common etiology resulting from the disruption of gonadal development during fetal life, the testicular dysgenesis syndrome (TDS). The hypothesis that in utero exposure to estrogenic agents could induce these disorders was first proposed in 1993. The only quantitative summary estimate of the association between prenatal exposure to estrogenic agents and testicular cancer was published over 10 years ago, and other systematic reviews of the association between estrogenic compounds, other than the potent pharmaceutical estrogen diethylstilbestrol (DES), and TDS end points have remained inconclusive. We conducted a quantitative meta-analysis of the association between the end points related to TDS and prenatal exposure to estrogenic agents. Inclusion in this analysis was based on mechanistic criteria, and the plausibility of an estrogen receptor (ER)-alpha-mediated mode of action was specifically explored. We included in this meta-analysis eight studies investigating the etiology of hypospadias and/or cryptorchidism that had not been identified in previous systematic reviews. Four additional studies of pharmaceutical estrogens yielded a statistically significant updated summary estimate for testicular cancer. The doubling of the risk ratios for all three end points investigated after DES exposure is consistent with a shared etiology and the TDS hypothesis but does not constitute evidence of an estrogenic mode of action. Results of the subset analyses point to the existence of unidentified sources of heterogeneity between studies or within the study population.

    Epigenetic mechanisms are emerging as mediators linking early environmental exposures during pregnancy with programmed changes in gene expression that alter offspring growth and development. There is irrefutable evidence from human and animal studies that nutrient and environmental agent exposures (for example, endocrine disruptors) during pregnancy may affect fetal/newborn development resulting in offspring obesity and obesity-associated metabolic abnormalities (metabolic syndrome). This concept of 'gestational programming' is associated with alterations to the epigenome (nongenomic) rather than changes in the DNA sequence (genomic). Epigenetic alterations induced by suboptimal maternal nutrition/endocrine factors include DNA methylation, histone modifications, chromatin remodeling and/or regulatory feedback by microRNAs, all of which have the ability to modulate gene expression and promote the metabolic syndrome phenotype. Recent studies have shown tissue-specific transcriptome patterns and phenotypes not only in the exposed individual, but also in subsequent progeny. Notably, the transmission of gestational programming effects to subsequent generations occurs in the absence of continued adverse environmental exposures, thus propagating the cycle of obesity and metabolic syndrome. This phenomenon may be attributed to an extrinsic process resulting from the maternal phenotype and the associated nutrient alterations occurring within each pregnancy. In addition, epigenetic inheritance may occur through somatic cells or through the germ line involving both maternal and paternal lineages. Since epigenetic gene modifications may be reversible, understanding how epigenetic mechanisms contribute to transgenerational transmission of obesity and metabolic dysfunction is crucial for the development of novel early detection and prevention strategies for programmed metabolic syndrome. In this review we discuss the evidence in human and animal studies for the role of

    Early myoclonus after cardiac arrest (CA) is traditionally viewed as a poor prognostic sign (status myoclonus). However, some patients may present early Lance-Adams syndrome (LAS): under appropriate treatment, they can reach a satisfactory functional outcome. Our aim was to describe their profile, focusing on pharmacologic management in the ICU, time to return of awareness, and long-term prognosis. Adults with early LAS (defined as generalized myoclonus within 96h, with epileptiform EEG within 48h after CA) were retrospectively identified in our CA registry between 2006 and 2016. Functional outcome was assessed through cerebral performance categories (CPC) at 3 months, CPC 1-2 defined good outcome. Among 458 consecutive patients, 7 (1.5%) developed early LAS (4 women, median age 59 years). Within 72h after CA, in normothemia and off sedation, all showed preserved brainstem reflexes and localized pain. All patients were initially treated with valproate, levetiracetam and clonazepam; additional agents, including propofol and midazolam, were prescribed in the majority. First signs of awareness occurred after 3-23 days (median 11.8); 3/7 reached a good outcome at 3 months. Early after CA, myoclonus together with a reactive, epileptiform EEG, preserved evoked potentials and brainstem reflexes suggests LAS. This condition was managed with a combination of highly dosed, large spectrum antiepileptic agents including propofol and midazolam. Even if awakening was at times delayed, good outcome occurred in a substantial proportion of patients. Copyright © 2017 Elsevier B.V. All rights reserved.

    The many motivations for employing agent-based computation in the social sciences are reviewed. It is argued that there exist three distinct uses of agent modeling techniques. One such use-the simplest-is conceptually quite close to traditional simulation in operations research. This use arises when equations can be formulated that completely describe a social process, and these equations are explicitly soluble, either analytically or numerically. In the former case, the agent model is merely a tool for presenting results, while in the latter it is a novel kind of Monte Carlo analysis. A second, more commonplace usage of computational agent models arises when mathematical models can be written down but not completely solved. In this case the agent-based model can shed significant light on the solution structure, illustrate dynamical properties of the model, serve to test the dependence of results on parameters and assumptions, and be a source of counter-examples. Finally, there are important classes of problems for which writing down equations is not a useful activity. In such circumstances, resort to agent-based computational models may be the only way available to explore such processes systematically, and constitute a third distinct usage of such models

    Full Text Available Patients with obstructed defecation syndrome (ODS form an important subset of patients with chronic constipation. Evaluation and treatment of these patients has traditionally been difficult. Magnetic resonance defecography (MRD is a very useful tool for the evaluation of these patients. We evaluated the scans and records of 192 consecutive patients who underwent MRD at our center between January 2011 and January 2012. Abnormal descent, rectoceles, rectorectal intussusceptions, enteroceles, and spastic perineum were observed in a large number of these patients, usually in various combinations. We discuss the technique, its advantages and limitations, and the normal findings and various pathologies.

    2014-11-01

    Full Text Available [english] Nail-patella syndrome (NPS is a pleiotropic autosomal-dominant disorder due to mutations in the gene LMX1B. It has traditionally been characterized by a tetrad of dermatologic and musculoskeletal abnormalities. However, one of the most serious manifestations of NPS is kidney disease, which may be present in up to 40% of affected individuals. Although diagnosis can be made at birth, it is often missed, presumably due to the rarity of the condition. A 35-year-old female presented to our clinic with history of small joint pain of 6 months duration. In addition she complained of pedal edema off and on for the last 12 years. Prior to her current presentation she had been managed by a local doctor symptomatically. On evaluation, a nephrotic syndrome was obvious, but no secondary cause could be found. However, her physical examination was characteristic of NPS and keeping in view the autosomal dominant nature of the disorder all her three siblings were screened who too showed classical features of NPS. This rare syndrome as a cause of nephrotic range proteinuria is discussed in this report. The report underlines the importance of a good physical examination in a given clinical setting.

  20. FTO is a relevant factor for the development of the metabolic syndrome in mice.

    Kathrin Ikels

    Full Text Available The metabolic syndrome is a worldwide problem mainly caused by obesity. FTO was found to be a obesity-risk gene in humans and FTO deficiency in mice led to reduction in adipose tissue. Thus, FTO is an important factor for the development of obesity. Leptin-deficient mice are a well characterized model for analysing the metabolic syndrome. To determine the relevance of FTO for the development of the metabolic syndrome we analysed different parameters in combined homozygous deficient mice (Lep(ob/ob;Fto(-/-. Lep(ob/ob;Fto(-/- mice showed an improvement in analysed hallmarks of the metabolic syndrome in comparison to leptin-deficient mice wild type or heterozygous for Fto. Lep(ob/ob;Fto(-/- mice did not develop hyperglycaemia and showed an improved glucose tolerance. Furthermore, extension of beta-cell mass was prevented in Lep(ob/ob;Fto(-/-mice and accumulation of ectopic fat in the liver was reduced. In conclusion this study demonstrates that FTO deficiency has a protective effect not only on the development of obesity but also on the metabolic syndrome. Thus, FTO plays an important role in the development of metabolic disorders and is an interesting target for therapeutic agents.

Given the pandemic spread of HCV infection and metabolic syndrome, the burden of their interaction is a major public health issue. The presence of metabolic syndrome accelerates the progression of liver disease in patients with HCV infection. New drug development in HCV has seen an unprecedented rise in the last year, which resulted in better efficacy, better tolerance, and a shorter treatment duration. This review describes the underlying mechanisms and clinical effects of metabolic syndrome in HCV infection, as well as their importance in the era of new directly acting antiviral therapy.

    2015-12-01

    Full Text Available Rett syndrome is an extremely disabling X-linked nervous system disorder that mainly affects girls in early childhood and causes autism-like behavior, severe intellectual disability, seizures, sleep disturbances, autonomic instability, and other disorders due to mutations in the MeCP2 (methyl CpG-binding protein 2 transcription factor. The disorder targets synapses and synaptic plasticity and has been shown to disrupt the balance between glutamate excitatory synapses and GABAergic inhibitory synapses. In fact, it can be argued that Rett syndrome is primarily a disorder of synaptic plasticity and that agents that can correct this imbalance may have beneficial effects on brain development. This review briefly summarizes the link between disrupted synaptic plasticity mechanisms and Rett syndrome and early clinical trials that aim to target these abnormalities to improve the outcome for these severely disabled children.

    Full Text Available This article concisely summarizes data on the action of one of the principal and best known growth factors, the granulocyte colony-stimulating factor (G-CSF, in a mammalian organism exposed to radiation doses inducing acute radiation syndrome. Highlighted are the topics of its real or anticipated use in radiation accident victims, the timing of its administration, the possibilities of combining G-CSF with other drugs, the ability of other agents to stimulate endogenous G-CSF production, as well as of the capability of this growth factor to ameliorate not only the bone marrow radiation syndrome but also the gastrointestinal radiation syndrome. G-CSF is one of the pivotal drugs in the treatment of radiation accident victims and its employment in this indication can be expected to remain or even grow in the future.

    Usher syndrome is both genetically and phenotypically heterogeneous. Traditionally, the condition has been classified into three clinical types, differentiated by the severity and progression of the hearing impairment and by the presence or absence of vestibular symptoms. Recent advances in molecular genetics have enabled researchers to study the phenotypic expression in confirmed molecular groups of Usher. In response to the expansion of clinical and genetic information on Usher, we report an up to date review of the different clinical forms of Usher in known molecular groups and use the emerging evidence to appraise the diagnostic utility of the traditional classification of Usher. Our findings undermine the traditional view that the clinical types of Usher have distinct genetic causes. The pleiotropic effects of some of the major causes of Usher lead to considerable overlap between the different clinical types, with very little evidence for phenotypic-genotypic correlations. The novel synthesis emerging from this review suggests more productive approaches to the diagnosis of Usher in hearing-impaired children which would provide more accurate prognostic information to families.

    2014-09-01

    Traditional African healing has been in existence for many centuries yet many people still seem not to understand how it relates to God and religion/spirituality. Some people seem to believe that traditional healers worship the ancestors and not God. It is therefore the aim of this paper to clarify this relationship by discussing a chain of communication between the worshipers and the Almighty God. Other aspects of traditional healing namely types of traditional healers, training of traditional healers as well as the role of traditional healers in their communities are discussed. In conclusion, the services of traditional healers go far beyond the uses of herbs for physical illnesses. Traditional healers serve many roles which include but not limited to custodians of the traditional African religion and customs, educators about culture, counselors, social workers and psychologists.

    Ramsay Hunt syndrome is a rare complication of the varicella zoster virus, defined as a peripheral facial palsy that typically results from involvement of the facial and auditory nerves. Ramsay Hunt syndrome can be associated with cranial nerves V, VI, IX, and X but rarely with XII. We describe an atypical case of Ramsay Hunt syndrome with multiple cranial nerve involvement of nerves V, VII, VIII, and XII. Antiviral drugs, antibiotics, insulin, and traditional Chinese drugs were administered immediately after admission. After 3 months of combination therapy, the patient had recovered satisfactorily. Herpes zoster can cause severe infections in diabetic patients and should be treated as soon after detection as possible. Ramsay Hunt syndrome should be recognized as a polycranial neuritis characterized by damage to sensory and motor nerves. In addition to facial and vestibular nerve paralysis, Ramsay Hunt syndrome may also involve cranial nerves V and XII.

  8. Incorporating BDI Agents into Human-Agent Decision Making Research

    Kamphorst, Bart; van Wissen, Arlette; Dignum, Virginia

    Artificial agents, people, institutes and societies all have the ability to make decisions. Decision making as a research area therefore involves a broad spectrum of sciences, ranging from Artificial Intelligence to economics to psychology. The Colored Trails (CT) framework is designed to aid researchers in all fields in examining decision making processes. It is developed both to study interaction between multiple actors (humans or software agents) in a dynamic environment, and to study and model the decision making of these actors. However, agents in the current implementation of CT lack the explanatory power to help understand the reasoning processes involved in decision making. The BDI paradigm that has been proposed in the agent research area to describe rational agents, enables the specification of agents that reason in abstract concepts such as beliefs, goals, plans and events. In this paper, we present CTAPL: an extension to CT that allows BDI software agents that are written in the practical agent programming language 2APL to reason about and interact with a CT environment.

    2010-01-01

    Chemical warfare agents are compounds of different chemical structures. Simple molecules such as chlorine as well as complex structures such as ricin belong to this group. Nerve agents, vesicants, incapacitating agents, blood agents, lung-damaging agents, riot-control agents and several toxins are among chemical warfare agents. Although the use of these compounds is strictly prohibited, the possible misuse by terrorist groups is a reality nowadays. Owing to this fact, knowledge of the basic properties of these substances is of a high importance. This chapter briefly introduces the separate groups of chemical warfare agents together with their members and the potential therapy that should be applied in case someone is intoxicated by these agents.

    In 1880, Jules Cotard reported a clinical state he believed was a new type of agitated melancholia. A statistical analysis has been carried out of 100 cases of Cotard's syndrome to determine how this clinical concept has fared since its inception. In terms of clinical profile, no difference was found between men and women or between underlying diagnostic categories; age seemed to increase the likelihood of developing délire des négations. Depression was reported in 89% of subjects; the most common nihilistic delusions concerned the body (86%) and existence (69%). Anxiety (65%) and guilt (63%) were also common, followed by hypochondriacal delusions (58%) and delusions of immortality (55). An exploratory factor analysis extracted 3 factors: psychotic depression, Cotard type I and Cotard type II. The psychotic depression factor included patients with melancholia and few nihilistic delusions. Cotard type 1 patients, on the other hand, showed no loadings for depression or other disease and are likely to constitute a pure Cotard syndrome whose nosology may be closer to the delusional than the affective disorders. Type II patients showed anxiety, depression and auditory hallucinations and constitute a mixed group. This new grouping cuts across the more traditional view and may have therapeutic implications. Authors, in general, have considered délire des négations as a syndrome rather than a new disease and do not seem to support the view that the completeness of the syndrome is a function of presence or severity of depression. The view that délire des négations refers only to the delusion of being dead has also carried little favour as its likely to waste information.

    Full Text Available Cyclic vomiting syndrome (CVS shares many features with migraine headache, including auras, photophobia, and antimigrainous treatment response being traditionally viewed as a migraine variant. Aims. To determine whether CVS is associated with the same disorders as migraine headache, and compare these associations to those in healthy control subjects. Methods. Cross-sectional study of patients utilizing the ODYSA instrument, evaluating the probability of 12 functional/autonomic diagnoses, CVS, migraine, orthostatic intolerance (OI, reflex syncope, interstitial cystitis, Raynaud's syndrome, complex regional pain syndrome (CRPS, irritable bowel syndrome, functional dyspepsia, functional abdominal pain, fibromyalgia, and chronic fatigue syndrome. Control subjects were age-matched gender-matched friends. Patients had to fulfill criteria for CVS or migraine, while control subjects could not. Results. 103 subjects were studied, 21 with CVS, 46 with migraine and 36 healthy controls. CVS and migraine did not differ in the relative frequencies of fibromyalgia, OI, syncope, and functional dyspepsia. However, CVS patients did demonstrate a significantly elevated frequency of CRPS. Conclusions. Although CVS and migraine clearly share many of the same comorbidities, they do differ in one important association, suggesting that they may not be identical in pathophysiology. Since OI is common in CVS, treatment strategies could also target this abnormality.

    It is not always possible to correlate the "emic" terms to the "etic" ones during ethnopharmacological surveys, especially regarding those related to Culture-Bound Syndromes (CBS). Nevertheless, it is the role of ethnopharmacology to address these correlations, since they are the basis for the understanding of potential bioactives. This study reports the clinical manifestations and therapeutic resources used for the treatment of CBS among some riverine inhabitants of Brazilian Amazonia. An effort was made to establish a correspondence between the local "emic" terms of traditional medicine and the symptoms or diseases known by conventional medicine ("etic" terms). The ultimate goal was to gain insights to suggest further pharmacological studies with the local resources. Fieldwork was guided by methods of anthropology, botany and zoology-with the assistance of a doctor-among the traditional healing experts in Jaú National Park (during 199 days in 1995) and Unini River Extractive Reserve (210 days from 2008 to 2012). Fifty-nine healers of different kinds were interviewed: a prayer-maker, medium, natural resource expert, massage therapist, midwife and snakebite healer. The clinical manifestations and healing resources of the following CBS were collected: "mau olhado" (evil eye), "quebrante" (chipping); "espante" (fright or susto); "doença do ar" (air diseases); "vento caído" (fallen wind); "derrame" (leakage); "mãe do corpo" (mother of the body) and "panema" (unlucky). The first three seem to be local variations of other CBSs already described in Latin America. "doença do ar", "vento caído", "derrame" and "mãe do corpo" seem to be folk terms for known conventional medical disorders, while "panema" is a yet undescribed Brazilian CBS that is possibly related to dysthymic disorder or depression and deserves further investigation. Treatments included prayer rituals, fumigation, baths and oral remedies using 25 plants and 10 animals. It was possible to establish

    Traditional Chinese medicine is one of the popular alternative treatments for cancer, mainly enhancing host immune response and reducing adverse effect of chemotherapy. This study first explored traditional Chinese medicine treatment effect on long-term survival of lung cancer patients. This study evaluated whether traditional Chinese medicine combined with conventional cancer treatment improved overall survival of lung cancer patients. We had conducted a retrospective cohort study on 111,564 newly diagnosed lung cancer patients in 2000-2009 from National Health Insurance Program database. A total of 23,803 (21.31%) patients used traditional Chinese medicine for lung cancer care. Eligible participants were followed up until 2011 with a mean follow-up period of 1.96 years (standard deviation 2.55) for non-TCM users and 3.04 years (2.85) for traditional Chinese medicine users. Patients with traditional Chinese medicine utilization were significantly more likely to have a 32% decreased risk of death [hazard ratio = 0.62; 95% confidence interval = 0.61-0.63], compared with patients without traditional Chinese medicine utilization after multivariate adjustment. We also observed a similar significant reduction risk across various subgroups of chronic lung diseases. Qing Zao Jiu Fei Tang was the most effective traditional Chinese medicine agent for mortality reduction both in the entire lung cancer (0.81; 0.72-0.91) and matched populations (0.86; 0.78-0.95). This study demonstrated adjunctive therapy with traditional Chinese medicine may improve overall survival of lung cancer patients. This study also suggested traditional Chinese medicine may be used as an adjunctive therapy for cancer treatment. These observational findings need being validated by future randomized controlled trials to rule out the possibility of effect due to holistic care.

We searched Medline, EMBASE, Web of Science, PubMed ePubs, and The Cochrane Library - CENTRAL through March 2015 without restrictions. Studies reporting cases of antiphospholipid syndrome or antiphospholipid syndrome-related features following an infection were included. Two hundred and fifty-nine publications met inclusion criteria, reporting on 293 cases. Three different groups of patients were identified; group 1 included patients who fulfilled the criteria for definitive antiphospholipid syndrome (24.6%), group 2 included patients who developed transient antiphospholipid antibodies with thromboembolic phenomena (43.7%), and group 3 included patients who developed transient antiphospholipid antibodies without thromboembolic events (31.7%). The most common preceding infection was viral (55.6%). In cases that developed thromboembolic events Human immunodeficiency and Hepatitis C viruses were the most frequently reported. Parvovirus B19 was the most common in cases that developed antibodies without thromboembolic events. Hematological manifestations and peripheral thrombosis were the most common clinical manifestations. Positive anticardiolipin antibodies were the most frequent antibodies reported, primarily coexisting IgG and IgM isotypes. Few patients in groups 1 and 2 had persistent antiphospholipid antibodies for more than 6 months. Outcome was variable with some cases reporting persistent antiphospholipid syndrome features and others achieving complete resolution of clinical events. Development of antiphospholipid antibodies with all traditional manifestations of antiphospholipid syndrome were observed after variety of infections, most frequently after chronic viral infections with Human immunodeficiency and Hepatitis C. The causal relationship between infection

    Approximately half of all patients with chronic obstructive pulmonary disease (COPD) attending pulmonary rehabilitation (PR) programmes are overweight or obese which negatively impacts upon dyspnoea and exercise tolerance particularly when walking. Within the obese population (without COPD), the observed heterogeneity in prognosis is in part explained by the variability in the risk of developing cardiovascular disease or diabetes (cardiometabolic risk) leading to the description of metabolic syndrome. In obesity alone, high-intensity aerobic training can support healthy weight loss and improve the constituent components of metabolic syndrome. Those with COPD, obesity and/or metabolic syndrome undergoing PR appear to do as well in traditional outcomes as their normal-weight metabolically healthy peers in terms of improvement of symptoms, health-related quality of life and exercise performance, and should therefore not be excluded. To broaden the benefit of PR, for this complex population, we should learn from the extensive literature examining the effects of exercise in obesity and metabolic syndrome discussed in this review and optimize the exercise strategy to improve these co-morbid conditions. Standard PR outcomes could be expanded to include cardiometabolic risk reduction to lower future morbidity and mortality; to this end exercise may well be the answer.

    We described three cases of superior mesenteric artery (SMA) syndrome, also known as Wilkie's syndrome, chronic duodenal ileus, or cast syndrome. This syndrome occurs when the third portion of the duodenum is compressed between the SMA and the aorta. The major risk factors for development of SMA syndrome are rapid weight loss and surgical correction of spinal deformities. The clinical presentation of SMA syndrome is variable and nonspecific, including nausea, vomiting, abdominal pain, and weight loss. The diagnosis is based on endoscopic, radiographic and tomographic findings of duodenal compression by the SMA. The treatment of SMA syndrome is aimed at the precipitating factor, which usually is related to weight loss. Therefore, conservative therapy with nutritional supplementation is the initial approach, and surgery is reserved for those who do not respond to nutritional therapy.

    Infertility is frequently caused by anovulation. The affected women present with irregular menstrual cycles and the most common diagnosis is polycystic ovary syndrome. Ovulation induction is commonly used to treat these women. Clomiphene citrate (a selective estrogen receptor modulator or SERM) remains the most used medication for treating this condition. Alternatives that have been used include other SERMs such as tamoxifen, aromatase inhibitors, insulin sensitizing agents, and ovarian drilling. Evidence for and against the effectiveness of these agents has fluctuated over the last decade. Controversies surrounding the use of ovulation induction such as development of functional cysts, high-order multiple births, and development of ovarian cancer have been further studied and some controversies have almost been laid to rest in the last decade.

  20. A Multi-Agent System Architecture for Sensor Networks

    Full Text Available The design of the control systems for sensor networks presents important challenges. Besides the traditional problems about how to process the sensor data to obtain the target information, engineers need to consider additional aspects such as the heterogeneity and high number of sensors, and the flexibility of these networks regarding topologies and the sensors in them. Although there are partial approaches for resolving these issues, their integration relies on ad hoc solutions requiring important development efforts. In order to provide an effective approach for this integration, this paper proposes an architecture based on the multi-agent system paradigm with a clear separation of concerns. The architecture considers sensors as devices used by an upper layer of manager agents. These agents are able to communicate and negotiate services to achieve the required functionality. Activities are organized according to roles related with the different aspects to integrate, mainly sensor management, data processing, communication and adaptation to changes in the available devices and their capabilities. This organization largely isolates and decouples the data management from the changing network, while encouraging reuse of solutions. The use of the architecture is facilitated by a specific modelling language developed through metamodelling. A case study concerning a generic distributed system for fire fighting illustrates the approach and the comparison with related work.
